Description

  TECHNICAL FIELD The present invention generally relates to a cooking device that cooks food to be cooked, and more particularly to a cooking device that cooks food using steam and / or superheated steam having a temperature exceeding 100 ° C. .

  2. Description of the Related Art Conventionally, as a cooking device, there is a cooking device that cooks food to be cooked such as food by steam or superheated steam of 100 ° C. or higher obtained by further heating steam. In such a cooking device, water supplied from a water supply tank or the like to the steam generator is heated to generate 100 ° C. steam. Moreover, superheated steam is produced | generated by heating the produced | generated water vapor to 100 degreeC or more. This steam or superheated steam is supplied into the heating chamber containing the food to be cooked, and when the heating time suitable for the food to be cooked has elapsed, Complete.

  For example, in the steam cooker described in JP-A-2005-48987 (Patent Document 1), water is put into a water tank that can be removed from the steam cooker, and the water tank is placed in the water tank chamber of the steam cooker. set. When the steam cooker is turned on, the water in the water tank is supplied to the water pot of the steam generator. When the steam generating heater of the steam generating device is energized, the water in the water pot is heated to become steam, and this steam is supplied to the heating chamber.

  In such a heating cooker, tap water is supplied to a water tank, tap water is supplied to a water pot of a steam generator, and heated to generate steam. Tap water contains impurities such as calcium ions and magnesium ions, and the use of the heating cooker may cause scale to deposit in the water tank, water pot, and piping. In the steam cooker described in JP-A-2005-48987 (Patent Document 1), the water tank can be removed from the steam cooker, so that the water tank can be washed.

In such an apparatus that generates water vapor using tap water, for example, in a humidifier described in JP 2000-346409 A (Patent Document 2), a heating tank that generates water vapor by heating water By making the heating element disposed inside the heating tank detachable from the heating tank, it is possible to clean the heating element to which the scale easily adheres and to remove the scale attached to the heating element.
JP 2005-48987 A JP 2000-346409 A

  However, in the steam cooker described in Japanese Patent Laid-Open No. 2005-48987 (Patent Document 1), the water pot in the steam generator and the pipe connecting the water tank and the water pot can be removed from the steam cooker. Because it is not possible, parts that are easily attached to the scale, such as a water pot where the water is heated, a pipe through which the heated water circulates, a pump for water supply, and a solenoid valve for drainage, are difficult to wash and prevent the scale from attaching. There is a problem that it is difficult to remove the scale. Further, in the humidifier described in Japanese Patent Application Laid-Open No. 2000-346409 (Patent Document 2), the scale is attached to the heating tank because the heating tank to which water is heated and the scale tends to adhere cannot be removed from the humidifier. It is difficult to prevent or remove the attached scale. Therefore, for these steam cookers and humidifiers, it is necessary to discard water after regular use of the steam cooker or humidifier or to periodically wash with citric acid so that the scale does not easily adhere.

  In addition, a container for heating water and generating water vapor, such as a water pot or a heating tank, cannot be removed from the steam cooker or humidifier. It is necessary to separately provide a container for generating water vapor. Piping and pumps that connect these containers, piping bands and sealing materials to prevent water leakage at the connecting parts of the containers and piping, solenoid valves to dispose of water from water pots and heating tanks, grounding, etc. are required. The parts which comprise a cooking appliance and a humidifier increase.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a cooking device for cooking a food to be cooked with steam, with a small number of components and a simple scale measure.

  The cooking device according to the present invention can be attached to and detached from the main body, the main body, a container for containing water, and disposed in the container to heat the water in the container to generate water vapor. A heating element for supplying water vapor from the container to the main body, and an induction heating coil arranged on the main body for induction heating of the heating element.

  In the heating element disposed in the container, an induction current is generated by driving the induction heating coil, and the heating element generates heat by the resistance heat of the induction current. Therefore, the heating element can generate heat without being electrically connected to the heating element and the induction heating coil. A heating element for heating water is disposed in the container, and an induction heating coil for inductively heating the heating element is disposed in the main body of the heating cooker, whereby the container for generating water vapor is electrically connected to the main body. Without being connected to the water, the water in the container can be heated to generate water vapor. In this way, a container for generating water vapor can be attached to and detached from the main body of the heating cooker.

  The water is heated in a container that can be attached to and detached from the main body of the heating cooker to become water vapor, and this water vapor is supplied to the main body through the water vapor supply means. Therefore, since the container in which water is easily heated and the scale easily adheres can be removed from the main body and easily washed, the scale becomes difficult to adhere to the container, and even if the scale adheres, the removal is easy.

  Moreover, unlike the conventional cooking device, there is no need to separately provide a water tank, a water pot, a pipe connecting these, a pump, a seal for preventing water leakage, and the like. Can be reduced. Since the number of components is small, it is possible to prevent water leakage and water vapor leakage at the connection portion between the components.

  By doing in this way, in the cooking-by-heating machine which cooks to-be-cooked material with water vapor | steam, there can be provided a heating cooking device with few components and a simple scale countermeasure.

  The cooking device according to the present invention can be attached to and detached from the main body, the main body, a container for containing water, and disposed in the container to heat the water in the container to generate water vapor. A heating element, a partition member for dividing the inside of the container into a first area where the heating element is disposed and a second area where the heating element is not disposed, and the heating element disposed in the main body An induction heating coil for induction heating.

  The water is heated into water vapor in a container that can be attached to and detached from the main body of the heating cooker. Therefore, since the container can be removed from the main body and easily cleaned, the scale does not easily adhere to the container, and even if the scale adheres, the removal is easy. Moreover, unlike the conventional cooking device, there is no need to separately provide a water tank, a water pot, a pipe connecting these, a pump, a seal for preventing water leakage, and the like. Can be reduced. Since the number of components is small, it is possible to prevent water leakage and water vapor leakage at the connection portion between the components.

  By doing in this way, in the cooking-by-heating machine which cooks to-be-cooked material with water vapor | steam, there can be provided a heating cooking device with few components and a simple scale countermeasure.

  In addition, by dividing the interior of the container with a partition member, water is generated if the water in the first region where the heating element is disposed is heated, so that all the water in the container is heated to generate water vapor. Water vapor can be generated more quickly and efficiently than in the case.

  In the heating cooker according to the present invention, the partition member includes a plurality of partition plates formed of a resin material, and water flows into the first region from the second region to the plurality of partition plates. Are preferably formed, and the plurality of partition plates are preferably arranged substantially parallel to each other.

  The resin material has a lower thermal conductivity than water. By using a plurality of partition plates formed of a resin material, the first region is divided into a first region where the heating element is disposed and the water is heated, and a second region where the heating element is not disposed. The heat of the heated water in the region is less likely to be taken away by the relatively cool water in the second region.

  Moreover, the heat insulation by a partition plate can be improved by arrange | positioning a several partition plate substantially parallel.

  Furthermore, since water flows into the first region from the second region through the opening, it becomes difficult for water having a relatively low temperature to flow into the first region. Can be generated.

  In the heating cooker according to this invention, it is preferable that the two openings formed in the two adjacent partition plates are formed at a position where the distance between the openings is maximized.

  By doing in this way, it becomes difficult for water with comparatively low temperature of the 2nd field to flow into the 1st field. For example, only an amount of water approximately equal to the amount of water heated and evaporated in the first region can flow from the second region into the first region, so that water is efficiently heated to generate water vapor. Can be made.

  In the cooking device according to the present invention, the main body preferably includes a heating chamber for supplying superheated steam generated by heating the steam in the container to 100 ° C. or more outside the container.

  By doing in this way, cooking can be performed using superheated steam in a heating cooker with few components and simple scale measures.

  In the cooking device according to the present invention, it is preferable that the heating element and the induction heating coil are arranged so that the heating element faces the induction heating coil when the container is attached to the main body.

  By doing in this way, the water in a container can be heated efficiently.

  In the cooking device according to the present invention, it is preferable that the heating element is disposed in the container so as to be detachable from the container.

  In this way, the heating element that easily adheres to the scale can be easily washed, so it is possible to more effectively prevent the scale from adhering to the heating element or remove the scale adhering to the heating element. Can be.

  In the heating cooker according to the present invention, the heating element has a facing surface facing the induction heating coil when the container is attached to the main body, and the heating element has a hole penetrating the facing surface of the heating element. Preferably it is formed.

  In order to increase the heating efficiency of the water in the container, it is necessary to reduce the distance between the heating element and the induction heating coil. Since the heating element is disposed in the container and the induction heating coil is disposed in the main body, when the distance between the heating element and the induction heating coil is reduced, the heating element approaches the wall surface and bottom surface of the container. When the heating element and the container come close to each other, bubbles generated by heating water between the heating element and the wall surface and bottom surface of the container are difficult to escape while remaining between the heating element and the wall surface and bottom surface of the container. Since liquid water is heated only up to 100 ° C., if the space between the heating element and the container is filled with liquid water, the heat of the heating element remains as it is even if the heating element is heated to 100 ° C. or higher. It is not transmitted to. On the other hand, if bubbles remain between the heating element and the wall or bottom of the container and the space between the heating element and the container is filled with water vapor, the water vapor is easily heated to 100 ° C. Body heat may be transferred to the container, causing the container to thermally deteriorate.

  Therefore, by forming a hole penetrating the heating element on the surface facing the induction heating coil, which is most easily heated by the heating element, bubbles generated between the heating element and the wall surface or bottom surface of the container pass through the hole. It is possible to prevent the heat deterioration of the container by diffusing into water and preventing the heating element and the container from coming into contact with each other through bubbles.

  In the cooking device according to the present invention, the heating element includes a heating element fixing portion for fixing the heating element, and the heating element is fixed by locking the heating element fixing portion on the upper portion of the container. It is preferable.

  When the heating element is induction-heated, the heating element may not move and move due to bubbles generated by the temperature rise of water and resonance with the induction heating coil. If the heating element moves, a stable input cannot be obtained.

  Therefore, by fixing the heating element fixing portion of the heating element to the container and fixing the heating element, the heating element can be stationary during induction heating, and by fixing the heating element at the upper part of the container, the heating element It becomes easy to put on and take off.

  In the cooking device according to the present invention, it is preferable that the heating element fixing portion is disposed above the surface of the water stored in the container.

  By doing in this way, even if the heated water is accommodated in the container, the heating element can be safely attached and detached.

  In the cooking device according to the present invention, the container preferably has an outer peripheral surface, and the outer peripheral surface of the container preferably includes an uneven surface.

  By doing in this way, even if a user touches a container, the heat of a container becomes difficult to be transmitted to a user.

  In the cooking device according to the present invention, when the container is removed from the main body, it is provided with a covering member for covering at least a part of the outer peripheral surface of the container, and the covering member is preferably formed of a resin material. .

  By doing in this way, it becomes difficult for a user to touch a container directly. Moreover, it becomes difficult for the heat of a container to be transmitted to a user.

  In the heating cooker according to the present invention, the heating element is formed of a temperature-sensitive magnetic material, and the Curie temperature of the temperature-sensitive magnetic material is in the range of 100 ° C. or more and the heat deformation temperature of the material forming the container. Preferably it is temperature.

  The temperature-sensitive magnetic material is induction-heated if the temperature is lower than the Curie temperature, and is not induction-heated if the temperature is higher than the Curie temperature. Therefore, by forming the heating element with a temperature-sensitive magnetic material having a Curie temperature of 100 ° C. or more and not more than the thermal deformation temperature of the material forming the container, the heating element heats the material forming the container. It is no longer heated to a temperature higher than the deformation temperature. By doing so, thermal deformation of the container can be prevented. Moreover, a temperature detection means and a temperature control means become unnecessary, and a safe cooking device with a simple configuration can be provided.

  In the heating cooker according to the present invention, the heating element has a facing portion that faces the induction heating coil when the container is attached to the main body, and the facing portion of the heating element is relative to the other portions. The thickness is preferably large.

  The heating element is most likely to generate heat at the facing portion facing the induction heating coil. On the other hand, the heating element is difficult to be heated in a portion where the thickness is large. Therefore, by making the opposed portion of the heating element relatively thicker than the other parts, the entire heating element can be heated uniformly, and bumping of water contained in the container can be prevented.

  The cooking device according to the present invention includes a container fixing member for fixing the container to the main body, and a drive unit for moving the container fixing member, and the drive unit has a temperature of the container equal to or higher than a predetermined temperature. In some cases, the container fixing member is preferably moved to a position where the container is fixed to the main body.

  By doing in this way, when a container is more than predetermined temperature, it can prevent that a user removes a container from a main part.

  As described above, according to the present invention, it is possible to provide a heating cooker that has a small number of components and that is easy to deal with scale, in a cooking device that cooks an object to be cooked with steam.

The body 230 faces the induction heating coil 171 arranged in the cabinet of the main body 100. When the control unit controls the IH circuit 172 to drive the induction heating coil 171, an induction current flows through the heating element 230 due to electromagnetic induction of the induction heating coil 171, and the heating element 230 generates heat due to resistance heat of the induction current. Thus, when the heat generating body 230 generates heat, the water 400 accommodated in the cup portion 210 is heated, and water vapor is generated in the evaporation cup 200.

  Water vapor generated in the evaporating cup 200 flows into the air supply pipe 136 of the main body 100 through the water vapor supply pipe 221 of the evaporating cup 200, passes through the circulation duct 135, and superheated water vapor installed in the ceiling portion of the heating chamber 120.

When the evaporating cup 201 is attached to the main body of the heating cooker 1, the induction heating coil 171 disposed in the main body 100 faces the heating element 230. When the lid part 220 is attached to the cup part 210, the water vapor supply pipe 221 is disposed above the heating part 211. The other configuration of the evaporating cup 201 and the configuration of the heating cooker including the evaporating cup 201 are the same as those in the first embodiment.

  The partition plate 240 has a plate shape and is arranged substantially vertically in the cup portion 210. An opening 241 that allows the water storage unit 212 and the heating unit 211 to communicate with each other is formed in the lower portion of the partition plate 240. The water in the cup part 210 can pass through the opening 241.

  When water 400 is stored in the evaporation cup 201 and the induction heating coil 171 is driven, the heating element 230 generates heat by electromagnetic induction, and water in the heating unit 211 in which the heating element 230 is disposed is heated to generate water vapor. To do. The generated water vapor passes through the water vapor supply pipe 221 and is guided from the discharge port 223 to the air supply pipe 136 (FIG. 1) of the main body.

  When the water 400 is heated in the heating unit 211 and water vapor is generated, the amount of the water 400 in the heating unit 211 decreases by an amount corresponding to the generated water vapor. When the amount of water 400 in the heating unit 211 decreases, water flows from the water storage unit 212 to the heating unit 211 through the opening 241.

  In the first embodiment, since the evaporating cup 200 does not have the partition plate 240, all the water 400 stored in the cup part 210 is heated by the heating element 230 at a time. On the other hand, in 2nd Embodiment, since the heat generating body 230 heats the water 400 in the heating part 211 instead of all the water accommodated in the cup part 210, in order to heat water efficiently, in a short time. Water vapor can be generated.

  In addition, the volume of the heating unit 211 is smaller than the entire volume of the cup unit 210, but when water vapor is generated and the amount of water stored in the cup unit 210 decreases, the water in the water storage unit 212 passes through the opening 241. The amount of water vapor that can be generated with a single supply of water using the evaporation cup 201 of the second embodiment is the same as that of the entire cup unit 210 using the evaporation cup 200 of the first embodiment. This is equivalent to the amount of water vapor that is generated when the is heated.

  Thus, the heating cooker 1 can be attached to and detached from the main body 100 and the main body 100, and is disposed in the evaporating cup 201 for accommodating the water 400 and the evaporating cup 201. In order to divide the heating element 230 for heating the water 400 to generate water vapor, the inside of the evaporation cup 201 into a heating part 211 where the heating element 230 is arranged, and a water storage part 212 where the heating element 230 is not arranged. Partition plate 240 and an induction heating coil 171 disposed on the main body 100 for induction heating of the heating element 230.

  The water 400 is heated in an evaporating cup 201 that can be attached to and detached from the main body 100 of the heating cooker 1 to become water vapor. Therefore, since the evaporation cup 201 can be removed from the main body 100 and easily cleaned, the scale does not easily adhere to the evaporation cup 201, and even if the scale adheres, the removal is easy. Moreover, it is not necessary to provide separately a water tank, a water pot, the piping which connects these, a pump, the seal for preventing a water leak, etc. like the conventional heating cooker, and the components which comprise the heating cooker 1 Can be reduced. Since the number of components is small, it is possible to prevent water leakage and water vapor leakage at the connection portion between the components.

  By doing in this way, in the cooking-by-heating machine which cooks food 300 with water vapor | steam, there can be provided the cooking-by-cooker 1 with few components and a simple scale countermeasure.

  In addition, by dividing the inside of the evaporation cup 201 by the partition plate 240, water is generated if the water in the heating unit 211 where the heating element 230 is arranged is heated, so that all the water in the evaporation cup 201 is heated. Water vapor can be generated more quickly and efficiently than when water vapor is generated.

  Other configurations and effects of the heating cooker 1 including the evaporation cup 201 of the second embodiment are the same as those of the heating cooker 1 of the first embodiment.

(Third embodiment)
The cooking device according to the third embodiment is different from the cooking device according to the first embodiment inside the evaporation cup.

  FIG. 5 is a diagram (A) schematically showing a side cross-section of an evaporation cup, and a diagram showing a cross section seen from the direction of line BB shown in FIG. 5 (A) as a third embodiment of the present invention. B).

  As shown in FIG. 5, the difference between the evaporating cup 202 and the evaporating cup 200 provided in the cooking device of the first embodiment is that the inside of the cup portion 210 is divided into two partition plates 240a and 240b as partition members. The first area is divided into a heating section 211 and the second area is divided into a water storage section 212. The partition plate 240a and the partition plate 240b are set up substantially vertically inside the cup part 210, and are arranged in parallel.

  The cup part 210, the partition plate 240a, and the partition plate 240b are formed of a resin material. As the resin material, polycarbonate resin (PC), polyphenylene sulfide resin (PPS), polybutylene terephthalate resin (PBT), or the like is used. These resin materials are excellent in heat resistance. The partition plate 240a and the partition plate 240b are plate-shaped, and the thickness is 1 mm in this embodiment. Moreover, the partition plate 240a and the partition plate 240b are arrange | positioned at intervals of 1-5 mm.

  An opening 241a and an opening 241b for communicating the water storage unit 212 and the heating unit 211 are formed in the lower portions of the partition plate 240a and the partition plate 240b, respectively. As shown in FIG. 5B, the opening 241a and the opening 241b are formed across the entire width of the cup portion 210, that is, the entire width of the partition plate 240a and the partition plate 240b, below the partition plate 240a and the partition plate 240b. Has been. The water in the cup part 210 can pass through the opening 241a and the opening 241b. If water does not pass through the opening 241a and the opening 241b, water cannot flow between the water storage unit 212 and the heating unit 211.

  The heating element 230 is disposed in the lower part in the heating unit 211. The heating element 230 is placed so as to be substantially horizontal on the fixing rib 252 protruding upward from the bottom surface inside the cup part 210, and is fixed by a fixing screw 251 that penetrates from the upper surface to the lower surface of the heating element 230. Screwed to the fixing rib 252. By removing the fixing screw 251, the heating element 230 can be removed from the cup part 210 and cleaned. The fixing screw 251 may be formed of resin. When the fixing screw 251 is made of resin, the fixing screw 251 is not induction-heated and does not generate heat. Therefore, by forming the fixing screw 251 with resin, even if the evaporation cup 202 is blown, the influence of heat on the evaporation cup 210 and the fixing rib 252 can be suppressed. When the evaporating cup 202 is attached to the main body 100 of the heating cooker 1, the induction heating coil 171 disposed in the main body 100 faces the heating element 230. When the lid part 220 is attached to the cup part 210, the water vapor supply pipe 221 is disposed above the heating part 211. Other configurations of the evaporating cup 202 and the configuration of the heating cooker including the evaporating cup 202 are the same as those in the first embodiment.

  When the water 400 is stored in the evaporation cup 202 and the induction heating coil 171 is driven, the heating element 230 generates heat by electromagnetic induction, and the water in the heating unit 211 in which the heating element 230 is disposed is heated to generate water vapor. To do. The generated water vapor passes through the water vapor supply pipe 221 and is guided from the discharge port 223 to the air supply pipe 136 (FIG. 1) of the main body 100.

  When the water 400 is heated in the heating unit 211 and water vapor is generated, the amount of the water 400 in the heating unit 211 decreases by an amount corresponding to the generated water vapor. When the amount of water 400 in the heating unit 211 decreases, water flows from the water storage unit 212 to the heating unit 211 through the opening 241a and the opening 241b.

  In the first embodiment, since the evaporating cup 200 does not have the partition plate 240a and the partition plate 240b, all the water 400 stored in the cup portion 210 is heated by the heating element 230 at a time. On the other hand, in 3rd Embodiment, since the heat generating body 230 heats the water 400 in the heating part 211 instead of all the water 400 accommodated in the cup part 210, in order to heat the water 400 efficiently, it is short. Water vapor can be generated over time.

  Moreover, although the volume of the heating part 211 is smaller than the whole volume of the cup part 210, if water vapor | steam generate | occur | produces and the quantity of the water accommodated in the cup part 210 reduces, the water of the water storage part 212 will be the opening part 241a. Therefore, the amount of water vapor that can be generated with a single water supply using the evaporation cup 202 of the third embodiment uses the evaporation cup 200 of the first embodiment. This is equivalent to the amount of water vapor generated when the entire cup part 210 is heated.

  In the second embodiment, one partition plate 240 is arranged in the cup part 210 to separate the heating unit 211 and the water storage unit 212. However, the two partition plates 240a and 240b , The heat of the heating unit 211 is less likely to be taken away by the water storage unit 212.

  In the third embodiment, the two partition plates 240a and the partition plates 240b are arranged in parallel in the horizontal direction, but may be arranged in the vertical direction.

  As described above, in the heating cooker according to the third embodiment, the partition member includes the plurality of partition plates 240a and the partition plates 240b formed of a resin material, and the plurality of partition plates 240a and the partition plates 240b include An opening 241a and an opening 241b for the water 400 to flow from the water storage unit 212 into the heating unit 211 are formed, and the plurality of partition plates 240a and the partition plates 240b are arranged substantially parallel to each other.

  The resin material has a lower thermal conductivity than water. Using a plurality of partition plates 240a and 240b formed of a resin material, a heating unit 211 in which the heating element 230 is disposed and the water is heated is divided into a water storage unit 212 in which the heating element 230 is not disposed. Thus, the heat of the heated water in the heating unit 211 is less likely to be taken away by water having a relatively low temperature in the water storage unit 212.

  Moreover, the heat insulation by the partition plate 240a and the partition plate 240b can be enhanced by arranging the plurality of partition plates 240a and the partition plate 240b substantially in parallel.

  Furthermore, since water flows into the heating part 211 from the water storage part 212 through the opening part 241a and the opening part 241b, it becomes difficult for water having a relatively low temperature to flow into the heating part 211, so that the water is efficiently heated. Water vapor can be generated.

  Other configurations and effects of the cooking device provided with the evaporation cup 202 of the third embodiment are the same as those of the cooking device of the first embodiment.

(Fourth embodiment)
The cooking device of the fourth embodiment differs from the cooking device of the third embodiment in the shape of the partition plate inside the evaporation cup.

  FIG. 6 is a diagram (A) schematically showing a side cross section of an evaporation cup, and a diagram showing a cross section seen from the direction of the line BB shown in FIG. 6 (A), as a fourth embodiment of the present invention. B).

  FIG. 7 is a top view of the evaporation cup of the fourth embodiment.

  As shown in FIG. 6, the two partition plates 240 c and the partition plate 240 d of the partition member divide the inside of the cup part 210 into a heating part 211 and a water storage part 212. The two partition plates 240c of the partition member and the opening 241c and the opening 241d of the partition plate 240d are formed below the partition plate 240c and the partition plate 240d. As shown in FIG. 6B and FIG. 7, the partition plate 240 c and the partition plate 240 d are arranged substantially vertically in the cup portion 210 and arranged in parallel. As shown in FIG. 6B, the opening 241c is formed in the lower right portion of the partition plate 240c, and the opening 241d is formed in the lower left portion of the partition plate 240d. The opening 241c and the opening 241d are formed by cutting off the corners of the partition plate 240c and the partition plate 240d. Is formed. The opening 241c and the opening 241d have a triangular shape with a side of about 5 mm. The opening 241c is formed so as to be in contact with one inner wall surface of the cup portion 210, and the opening 241d is formed so as to be in contact with the other inner wall surface facing one inner wall surface with which the opening 241c is in contact. The distance between the opening 241 c and the opening 241 d is substantially equal to the width of the cup part 210.

  The cup part 210, the partition plate 240c, and the partition plate 240d are formed of a resin material. As the resin material, polycarbonate resin (PC), polyphenylene sulfide resin (PPS), polybutylene terephthalate resin (PBT), or the like is used. These resin materials are excellent in heat resistance. The partition plate 240c and the partition plate 240d are plate-like, and the thickness is 1 mm in this embodiment.

  In the fourth embodiment, the distance D between the partition plate 240c and the partition plate 240d is 1 to 5 mm. The thermal conductivity of water is 0.57 W / mK, and the thermal conductivity of resin is about 0.2 W / mK. Therefore, the shorter the distance between the partition plate 240c and the partition plate 240d, the less the heat flows between the water storage unit 212 and the heating unit 211. However, when the interval between the partition plate 240c and the partition plate 240d is smaller than 1 mm, it becomes difficult for water to flow between the opening 241d and the opening 241c, and the amount of water stored is larger than the amount of water evaporated in the heating unit 211. The amount of water flowing from the section 212 into the heating section 211 is smaller. When the amount of water flowing from the water storage unit 212 into the heating unit 211 is smaller than the amount of water evaporated in the heating unit 211, the evaporation cup 203 is blown away. Therefore, the distance D between the partition plate 240c and the partition plate 240d is set to 1 to 5 mm in consideration of heat insulation and water flow.

  When the water 400 is heated in the heating unit 211 and water vapor is generated, the amount of the water 400 in the heating unit 211 decreases by an amount corresponding to the generated water vapor. When the amount of the water 400 in the heating unit 211 decreases, the water in the water storage unit 212 passes through the opening 241d of the partition plate 240d and the partition plate 240d and the partition plate as shown by a two-dot chain line arrow in FIG. 240c, moves in the horizontal direction by the width of the cup part 210, reaches the opening 241c, flows into the heating part 211 through the opening 241c.

  As described above, in the heating cooker according to the fourth embodiment, the two openings 241c and 241d formed in the two adjacent partition plates 240c and 240d have a distance between the openings. It is formed at the maximum position.

  By doing in this way, it becomes difficult for water with comparatively low temperature of the water storage part 212 to flow into the heating part 211. For example, since only an amount of water approximately equal to the amount of water heated and evaporated in the heating unit 211 can flow into the heating unit 211 from the water storage unit 212, water can be efficiently heated to generate water vapor. it can.

  The two openings formed in the partition plate 240c and the partition plate 240d may be formed in the partition plate 240c and the partition plate 240d, respectively, at positions separated from each other by a predetermined distance in the direction along the partition plate.

  Other configurations and effects of the cooking device of the fourth embodiment are the same as those of the cooking device of the third embodiment.

(Fifth embodiment)
The cooking device of the fifth embodiment differs from the cooking device of the third embodiment in the shape of the heating element.

  FIG. 8 is a view schematically showing a side cross section of a cup portion of an evaporation cup as a fifth embodiment of the present invention. FIG. 9 is a top view of the cup portion of the evaporation cup as the fifth embodiment of the present invention. FIG. 10 is a perspective view showing the entire heating element.

  As shown in FIGS. 8 to 10, the heating element 230 a includes a rectangular facing surface 231 that faces the bottom surface of the cup portion 210, and a rising portion 234 that extends upward around the facing surface 231. Two edge portions 235 are provided. The two rising portions 234 face each other. Further, the two edge portions 235 face each other. The edge portion 235 extends upward from the facing surface 231 in order to prevent deformation of the heating element 230. The height of the edge portion 235 is lower than the height of the rising portion 234. The rising portion 234 is bent at the upper portion so as to be parallel to the upper end surface of the wall of the cup portion 210 and the upper end surface of the partition plate 240 to form a heating element fixing portion 233a.

  A fixing hole 236 through which a fixing screw 253 for locking the heating element fixing portion 233a to the upper end surface of the cup portion 210 and the upper end surface of the partition plate 240 is formed in the heating element fixing portion 233a. It is assumed that the water level of the water stored in the cup part 210 is lower than the upper end face of the cup part 210 and the upper end face of the partition plate 240. The heating element 230a is fixed to the cup part 210 through the fixing screw 253 in the fixing hole 236 of the heating element fixing part 233a. The heating element 230a can be removed from the cup portion 210 by removing the fixing screw 253.

  The heating element 230a fixed by the fixing screw 253 can be easily produced and processed.

  When the heat generating body 230 is locked to the cup part 210 and the partition plate 240 and the cup part 210 is attached to the heating cooker 1 (FIG. 1), the facing surface 231 of the heat generating body 230a is formed on the heating cooker 1 (FIG. 1). It faces the induction heating coil 171 arranged in the main body 100 (FIG. 1). A plurality of holes 232 are formed in the facing surface 231 of the heating element 230a.

  FIG. 11 is a plan view showing one shape of the facing surface of the heating element. FIG. 12 is a plan view showing another shape of the facing surface of the heating element.

  As shown in FIGS. 11 and 12, a hole 232 that penetrates the facing surface 231 is formed in the facing surface 231 of the heating element 230a. A plurality of holes 232 are formed along the shape of the induction heating coil 171 that faces the facing surface 231 when the evaporating cup in which the heating element 230a is disposed is attached to the heating cooker. Since the induction heating coil 171 has a donut shape when viewed from above, the holes 232 are arranged in a circle. The diameter of each hole 232 is preferably 3 mm or more. If the diameter of the hole 232 is 5 mm, the holes 232 need only be formed at four locations as shown in FIG. The diameter of the hole 232 may be increased to such an extent that adjacent holes 232 are not connected to each other.

  As described above, in the heating cooker according to the fifth embodiment, the heating element 230a has the facing surface 231 that faces the induction heating coil 171 when the cup unit 210 is attached to the main body. A hole 232 that penetrates the facing surface 231 of the heating element 230a is formed.

  In order to increase the heating efficiency of the water in the cup part 210, it is necessary to reduce the distance between the heating element 230a and the induction heating coil 171. Since the heating element 230a is disposed in the cup part 210 and the induction heating coil 171 is disposed in the main body, when the distance between the heating element 230a and the induction heating coil 171 is reduced, the heating element 230a is brought into contact with the bottom surface of the cup part 210. Get closer. When the heating element 230a and the cup part 210 approach each other, bubbles generated by heating water between the heating element 230a and the bottom surface of the cup part 210 remain between the heating element 230a and the bottom surface of the cup part 210. It becomes difficult to come off. Since liquid water is heated only up to 100 ° C., if the space between the heating element 230a and the cup part 210 is filled with liquid water, the heating element 230a is heated even if the heating element 230a is heated to 100 ° C. or higher. The heat is not transmitted to the cup part 210 as it is. On the other hand, when air bubbles remain between the heating element 230a and the bottom surface of the cup part 210 and the space between the heating element 230a and the cup part 210 is filled with water vapor, the water vapor is easily heated to 100 ° C. or more. Therefore, the heat of the heating element 230a is transmitted to the cup part 210, and the cup part 210 may be thermally deteriorated.

  Therefore, a hole 232 that penetrates the heating element 230a is formed in the facing surface 231 that faces the induction heating coil 171 and is most easily heated in the heating element 230a, and is generated between the heating element 230a and the bottom surface of the cup portion 210. The air bubbles diffused into the water through the holes 232 and the heating element 230a and the cup part 210 are prevented from coming into contact with each other through the air bubbles, so that the heat deterioration of the cup part 210 can be prevented.

  Further, as described above, in the cooking device, the heating element 230a includes the heating element fixing part 233a for fixing the heating element 230a, and the heating element 230a is located above the cup part 210 at the heating element fixing part 233a. Is fixed by being locked.

  When the heating element 230a is induction-heated, the heating element 230a may not move and move due to bubbles generated by the temperature rise of water and resonance with the induction heating coil 171. When the heating element 230a moves, a stable input cannot be obtained.

  Accordingly, the heating element fixing portion 233a of the heating element 230a is locked to the cup portion 210 to fix the heating element 230a, so that the heating element 230a can be stationary during induction heating, and the upper portion of the cup portion 210 can be fixed. By fixing at, the heating element 230a can be easily attached and detached.

  Further, as described above, in the cooking device, the heating element fixing portion 233a is disposed above the surface of the water stored in the cup portion 210.

  By doing in this way, even if the heated water is accommodated in the cup part 210, the heat generating body 230a can be safely attached or detached.

  Other configurations and effects of the cooking device of the fifth embodiment are the same as those of the cooking device of the second embodiment.

(Sixth embodiment)
The cooking device of the sixth embodiment differs from the cooking device of the fifth embodiment in the shape of the heating element and the method of locking the heating element fixing portion.

  FIG. 13: is a figure which shows schematically the side cross section of the cup part of an evaporation cup as 6th Embodiment of this invention. FIG. 14 is a perspective view showing a part of the wall of the heating element and the cup portion.

  As shown in FIGS. 13 and 14, the overall shape of the heating element 230b is the same as that of the heating element 230a of the fifth embodiment. The heating element 230b is different from the heating element 230a of the fifth embodiment in that no fixing hole is formed in the heating element fixing portion 233b. Further, a claw 254 for locking the heating element fixing portion 233b is formed on the upper end surface of the wall of the cup portion 210 and the upper end surface of the partition plate 240. The heating element fixing portion 233 b is fixed to the cup portion 210 by being sandwiched between the lower surface of the claw 254 and the upper end surface of the wall of the cup portion 210 and between the claw 254 and the upper end surface of the partition plate 240.

  Since the heating element fixing part 233b of the heating element 230b is fixed by being sandwiched between the cup part 210 or the claws 254 of the partition plate 240, the heating element 230b is easily attached and detached as compared with the case of fixing with screws as in the fifth embodiment. be able to.

  As described above, in the heating cooker according to the sixth embodiment, the heating element 230b includes the heating element fixing portion 233b for fixing the heating element 230b, and the heating element 230b is disposed above the cup portion 210. The fixing portion 233b is fixed by being locked.

  When the heating element 230b is induction-heated, the heating element 230b may not move and move due to bubbles generated by the temperature rise of water and resonance with the induction heating coil 171. If the heating element 230b moves, a stable input cannot be obtained.

  Therefore, by fixing the heating element fixing portion 233b of the heating element 230b to the cup part 210 and fixing the heating element 230b, the heating element 230b can be stationary during induction heating, and the upper part of the cup part 210 can be fixed. By fixing at, the heating element 230b can be easily attached and detached.

  Further, as described above, in the heating cooker, the heating element fixing portion 233b is disposed above the surface of the water stored in the cup portion 210.

  By doing in this way, even if the heated water is accommodated in the cup part 210, the heating element 230b can be safely attached and detached.

  Other configurations and effects of the cooking device of the sixth embodiment are the same as those of the cooking device of the fifth embodiment.

(Seventh embodiment)
The cooking device of the seventh embodiment differs from the cooking device of the fifth embodiment in the shape of the heating element and the method of locking the heating element fixing portion.

  FIG. 15 is a view schematically showing a side cross section of a cup portion of an evaporation cup as a seventh embodiment of the present invention. FIG. 16 is a perspective view showing the entire heating element. FIG. 17 is a cross-sectional view (A) showing a part of the wall of the heating element and the cup part, and a view (B) when the cup part shown in (A) is viewed from the right direction.

  As shown in FIGS. 15-17, the heat generating body 230c differs from the heat generating body 230a of 5th Embodiment in the shape of the heat generating body fixing | fixed part 233c. The heating element fixing portion 233c is bent such that the rising portion 234 of the heating element 230c is parallel to the upper end surface of the wall of the cup portion 210 and the upper end surface of the partition plate 240 at the upper portion, and further bent downward. Thus, a U-shaped heating element fixing portion 233c is formed. The cup 210 is connected to a fixing lid 255 for locking the heating element fixing part 233c of the heating element 230c. The fixing lid 255 is made of a nonmetallic material.

  Concave portions 255 c and cut portions 255 d are formed on the upper end surface of the wall of the cup portion 210 and the upper end surface of the partition plate 240. The bent tip portion of the heating element fixing portion 233c of the heating element 230c is inserted into the cut portion 255d. The leg portion 255b of the fixing lid 255 is inserted into the concave portion 255c. The fixing lid 255 covers the upper surface of the heating element fixing portion 233c. Thus, since the upper surface of the heating element fixing portion 233c is covered with the nonmetallic material, safety is improved. Moreover, since the fixing lid 255 is fitted from above, the heating element 230c can be easily attached and detached.

  As described above, in the heating cooker, the heating element 230c includes the heating element fixing part 233c for fixing the heating element 230c, and the heating element 230c is associated with the heating element fixing part 233c above the cup part 210. It is fixed by being stopped.

  When the heating element 230c is induction-heated, the heating element 230c may move without being stationary due to bubbles generated by the temperature rise of water or resonance with the induction heating coil 171. When the heating element 230c moves, a stable input cannot be obtained.

  Therefore, by fixing the heating element fixing portion 233c of the heating element 230c to the cup part 210 and fixing the heating element 230c, the heating element 230c can be made stationary during induction heating, and the upper part of the cup part 210 can be fixed. By fixing at, the heating element 230c can be easily attached and detached.

  Further, as described above, in the heating cooker, the heating element fixing portion 233c is disposed above the surface of the water stored in the cup portion 210.

  By doing in this way, even if the heated water is accommodated in the cup part 210, the heating element 230c can be safely attached and detached.

  Other configurations and effects of the cooking device of the seventh embodiment are the same as those of the cooking device of the fifth embodiment.

(Eighth embodiment)
The cooking device of the eighth embodiment differs from the cooking device of the first embodiment in the shape of the evaporation cup.

  FIG. 18 is a front view (A) and a side view (B) schematically showing the entire evaporation cup as an eighth embodiment of the present invention.

  As shown in FIG. 18, the evaporating cup 204 of the eighth embodiment is different from the evaporating cup 200 of the first embodiment in that the outer peripheral surface of the evaporating cup 204 is below the water vapor supply pipe 221, that is, the evaporating cup. When the evaporating cup 204 is attached to the heating cooker 1 (FIG. 1) close to the heating element disposed inside 204, an uneven surface 213 is formed in a portion disposed above the induction heating coil 171. ing. The uneven surface 213 is formed by arranging a large number of ribs on the outer peripheral surface of the cup portion 210 of the evaporating cup 204.

  The evaporation cup 204 is made of a synthetic resin, ceramic, or a material obtained by combining these metal materials. As the resin material, polycarbonate resin (PC), polyphenylene sulfide resin (PPS), polybutylene terephthalate resin (PBT), or the like is used. Thus, when the user removes the evaporating cup 204 from the main body 100 (FIG. 1) of the heating cooker, even if the evaporating cup 204 is hot, the heat of the evaporating cup 204 is not easily transmitted to the user. . Further, since the uneven surface 213 is formed on the outer peripheral surface, the heat of the evaporating cup 204 is further hardly transmitted to the user.

  As described above, in the cooking device of the eighth embodiment, the evaporation cup 204 has an outer peripheral surface, and the outer peripheral surface of the evaporation cup 204 includes the uneven surface 213.

  By doing in this way, even if a user touches the evaporation cup 204, the heat of the evaporation cup 204 becomes difficult to be transmitted to a user.

  Other configurations and effects of the cooking device of the eighth embodiment are the same as those of the cooking device of the first embodiment.

(Ninth embodiment)
FIG. 19: is a side view (A) which shows the whole evaporating cup with which a heating cooker is provided, and a side view (B) which shows the whole outer container of an evaporating cup as 9th Embodiment of this invention.

  As shown in FIG. 19A, a heating element 230 is disposed inside the evaporation cup 205 below the water vapor supply pipe 221. A slide cover 261 is disposed on the evaporating cup 205 as a covering member that covers the evaporating cup 205 from the outside around the heating element 230. The slide cover 261 is formed in a U-shape in which an upper surface and two side surfaces facing each other adjacent to the upper surface are opened. The cup part 210 is inserted from above the slide cover 261. A handle 214 for holding by the user is formed on the top of the evaporation cup 205.

  A front cover 263 is attached to the front surface of the cup portion 210 of the evaporation cup 205, that is, the side where the water vapor supply pipe 221 is disposed. The slide cover 261 is not slid toward the front of the cup part 210 beyond the front cover 263.

  A semispherical hemispherical protrusion 262 that protrudes outward from the bottom surface of the cup part 210 is formed in the center of the bottom surface of the cup part 210 of the evaporation cup 205. Since the edge of the slide cover 261 is caught by the hemispherical protrusion 262, the slide cover 261 is not slid beyond the hemispherical protrusion 262 unless a force is applied. The slide cover 261 has a rectangular parallelepiped rear protrusion 264 that protrudes outward from the bottom surface behind the hemispherical protrusion 262.

  As shown in FIG. 19B, the outer container 180 has an opening for inserting the evaporating cup 205 on the rear side, that is, on the left side of the figure, and on the front side, that is, on the right side of the figure. A steam port 183 for discharging steam is formed. When the evaporating cup 205 is housed inside the outer container 180, the water vapor supply pipe 221 of the evaporating cup 205 is inserted into the steam port 183 from the inside of the outer container 180. A thermistor 182 is disposed on the front surface of the outer container 180, that is, on the side surface where the steam port 183 is formed. When the evaporating cup 205 is housed inside the outer container 180, the thermistor 182 comes into contact with the wall surface of the cup portion 210 of the evaporating cup 205 and the temperature of the cup portion 210 can be detected. A hemispherical projection 181 is formed on the inner bottom surface of the outer container 180 so as to project inward from the bottom surface. The outer container 180 is a container disposed on the main body 100 (FIG. 1) of the heating cooker 1. The induction heating coil 171 and the IH circuit 172 are disposed below the outer container 180.

  The slide cover 261 is made of a resin material. As the resin material, polycarbonate resin (PC), polyphenylene sulfide resin (PPS), polybutylene terephthalate resin (PBT), or the like is used.

  FIG. 20 is a side view (A) and a bottom view (B) showing the state of the first stage when the evaporation cup is accommodated in the outer container.

  As shown in FIG. 20, the evaporation cup 205 is inserted into the outer container 180 from the rear side of the outer container 180 while the user holds the handle 214. The front edge of the slide cover 261 catches on the protrusion 181 on the bottom surface of the outer container 180, and the slide cover 261 does not move forward than the protrusion 181. On the other hand, the evaporating cup 205 is inserted further forward in the outer container 180 with the hemispherical protrusion 262 on the bottom surface of the cup portion 210 getting over the edge of the slide cover 261.

  FIG. 21 is a side view (A) and a bottom view (B) showing the state of the second stage when the evaporation cup is accommodated in the outer container.

  As shown in FIG. 21, when the evaporating cup 205 moves forward in the outer container 180, the rear protrusion 264 contacts the slide cover 261, and when the evaporating cup 205 is pushed forward, the slide cover 261 moves rearward. It catches on the protrusion 264 and is pushed by the rear protrusion 264 to move over the protrusion 181 and move forward.

  FIG. 22 is a side view (A) and a bottom view (B) showing a state in which the evaporation cup is housed inside the outer container.

  As shown in FIG. 22, when the evaporation cup 205 is further pushed into the outer container 180 from the state shown in FIG. 21, the slide cover 261 is pushed by the rear protrusion 264 and advances forward in the outer container 180. When the evaporating cup 205 is inserted until the front cover 263 of the evaporating cup 205 contacts the inner wall on the front side of the outer container 180, the evaporating cup 205 is housed in the outer container 180. At this time, the heating element 230 is disposed so as to face the induction heating coil 171. Further, the rear edge of the slide cover 261 is in front of the protrusion 181.

  In a state where the evaporation cup 205 is accommodated in the outer container 180 in this manner, the heating element 230 is induction-heated, and water vapor is generated in the evaporation cup 205. The generated water vapor is supplied to the air supply pipe 136 (FIG. 1) of the heating cooker 1 (FIG. 1) through the water vapor supply pipe 221 of the evaporation cup 205 and the steam port 183 of the outer container 180.

  FIG. 23 is a side view (A) and a bottom view (B) showing the state of the first stage when pulling out the evaporating cup from the outer container.

  As shown in FIG. 23, when the evaporating cup 205 is pulled out from the outer container 180 to the rear side, the slide cover 261 does not move because the rear edge is caught on the protrusion 181. Only the portion of the evaporation cup 205 excluding the slide cover 261 moves backward.

  FIG. 24 is a side view (A) and a bottom view (B) showing the state of the second stage when pulling out the evaporation cup from the outer container.

  As shown in FIG. 24, when the evaporation cup 205 is further pulled out, the front cover 263 of the evaporation cup 205 comes into contact with the front side of the slide cover 261.

  FIG. 25 is a side view (A) and a bottom view (B) showing the state of the third stage when pulling out the evaporating cup from the outer container.

  As shown in FIG. 25, when the evaporation cup 205 is further pulled out rearward, the front cover 263 of the evaporation cup 205 pushes the slide cover 261 rearward, and the slide cover 261 moves over the protrusion 181 and moves rearward.

  When the evaporating cup 205 is pulled out as it is, the evaporating cup 205 is completely removed from the outer container 180 and removed together with the slide cover 261 pushed by the front cover 263.

  In the evaporation cup 205 removed from the outer container 180 in this manner, the peripheral portion of the heating element 230 is covered with the slide cover 261 as shown in FIG. Since the slide cover 261 is formed of a resin material, heat is hardly transmitted. In addition, as shown in FIG. 22, when the evaporation cup 205 is attached to the heating cooker and heated, the slide cover 261 is separated from the heating element 230, so that the slide cover 261 is guided by the heating element 230. Difficult to be heated during heating. In this way, even if the user touches the slide cover 261 of the evaporation cup 205 removed from the cooking device, the user can be prevented from being burned.

  As described above, the heating cooker according to the ninth embodiment includes the slide cover 261 for covering at least a part of the outer peripheral surface of the evaporation cup 205 when the evaporation cup 205 is removed from the main body 100. 261 is made of a resin material.

  By doing in this way, it becomes difficult for a user to touch the evaporation cup 205 directly, and it becomes difficult for the heat of the evaporation cup 205 to be transmitted to a user.

  Other configurations and effects of the cooking device of the ninth embodiment are the same as those of the cooking device of the first embodiment.

(10th Embodiment)
FIG. 26 is a perspective view showing the entire heating element as the tenth embodiment.

  As shown in FIG. 26, the heating element 230d is formed in a shallow rectangular parallelepiped box shape having an upper surface opened. Four edge portions 235 are formed around the rectangular opposing surface 231. The edge portion 235 is formed to prevent the heat generating body 230d from being deformed.

  A donut-shaped facing portion 237 is formed on the facing surface 231 of the heating element 230d. The facing portion 237 is a portion facing the induction heating coil 171 (FIG. 1) when the heating element 230d is attached to the evaporation cup and the evaporation cup is attached to the heating cooker, and from the facing surface 231 of the heating element 230d. It is formed with a thickness so as to protrude. Since the induction heating coil 171 is a coil concentrically wound, the plurality of facing portions 237 are formed concentrically so as to face the induction heating coil 171.

  The heating element 230d is made of stainless steel and is subjected to electrolytic polishing treatment. By doing so, a smooth polished surface is formed on the surface of the heating element 230d, and the heating element 230d can be easily cleaned, and the corrosion resistance of the heating element 230d can be improved.

  The heating element 230d is made of an Fe—Ni-based temperature sensitive magnetic material.

  FIG. 27 is a diagram showing a change in Curie temperature when the ratio of nickel (Ni) is changed in the Fe—Ni-based temperature-sensitive magnetic material.

  Table 1 shows the Curie temperature of the Fe-Ni thermosensitive magnetic material when the proportion of nickel is 30%, 35%, and 40%.

  As shown in FIG. 27 and Table 1, for example, the heating element 230d having a Curie temperature in the range of 100 ° C. to 200 ° C. can be formed by setting the ratio of nickel to 30 to 40%.

  The evaporation cup in which the heating element 230d is disposed is formed of a resin material such as polycarbonate resin (PC), polyphenylene sulfide resin (PPS), or polybutylene terephthalate resin (PBT), or a non-metallic material such as ceramic. The thermal deformation temperatures of these materials are 130 ° C. to 140 ° C. for polycarbonate resin (PC), 260 ° C. for polyphenylene sulfide resin (PPS), and 220 ° C. for polybutylene terephthalate resin (PBT) (glass reinforced product).

  When the evaporation cup is made of polyphenylene sulfide resin (PPS), the heating element 230d is made of an Fe—Ni thermosensitive magnetic material having a nickel content of 35%. At this time, the Curie temperature of the temperature-sensitive magnetic material forming the heating element 230d is 220 ° C. When the heating element 230d is formed of an Fe-Ni thermosensitive magnetic material having a nickel ratio of 35%, the evaporating cup has a polybutylene terephthalate resin (PBT) (glass) having a thermal deformation temperature of 220 ° C. It is desirable that it is not formed by a reinforced product. Since the Curie temperature of the heating element 230d formed of the Fe-Ni thermosensitive magnetic material having a nickel ratio of 35% is 220 ° C, the heating element 230d is heated up to 220 ° C. When the evaporating cup is formed of polybutylene terephthalate resin (PBT) having a heat distortion temperature of 220 ° C., if the heating element 230d is heated to 220 ° C., the evaporating cup may vary depending on the material variation and the evaporating cup thickness. May be deformed, so there is no design margin.

  FIG. 28 is a diagram schematically illustrating the lines of magnetic force around the heating element when the temperature is a temperature equal to or lower than the Curie temperature (A) and when the temperature is equal to or higher than the Curie temperature (B).

  As shown in FIG. 28A, when the temperature of the heating element 230d disposed in the cup portion 210 of the evaporation cup is lower than the Curie temperature, the magnetic lines of force 173 pass through the heating element 230d. Therefore, the heating element 230d is induction heated.

  On the other hand, as shown in FIG. 28B, when the temperature of the heating element 230d is higher than the Curie temperature, the magnetic lines of force 173 do not pass through the heating element 230d. Therefore, the heating element 230d is not induction-heated, so that the temperature does not rise further.

  As described above, in the cooking device of the tenth embodiment, the heating element 230d is formed of a temperature-sensitive magnetic material, and the Curie temperature of the temperature-sensitive magnetic material is 100 ° C. or higher, and the heat of the material forming the evaporation cup. The temperature is within the range below the deformation temperature.

  The temperature-sensitive magnetic material is induction-heated if the temperature is lower than the Curie temperature, and is not induction-heated if the temperature is higher than the Curie temperature. Therefore, the heating element 230d forms the evaporation cup by forming the heating element 230d with a temperature-sensitive magnetic material having a Curie temperature of 100 ° C. or more and a temperature within the range of the heat deformation temperature of the material forming the evaporation cup. The material is not heated to a temperature higher than the heat deformation temperature of the material to be processed. By doing in this way, the heat deformation of an evaporation cup can be prevented. Moreover, a temperature detection means and a temperature control means become unnecessary, and a safe cooking device with a simple configuration can be provided.

  Further, in the cooking device of the tenth embodiment, the heating element 230d has a facing part 237 that faces the induction heating coil 171 when the evaporation cup is attached to the main body, and the facing part 237 of the heating element 230d is It is preferable that the thickness is relatively larger than other portions.

  The heating element 230d is most likely to generate heat at the facing portion 237 facing the induction heating coil 171. On the other hand, the heating element 230d is not easily heated in a portion where the thickness is large. Therefore, by making the facing portion 237 of the heating element 230d relatively thick compared to other parts, the entire heating element 230d can be uniformly heated to prevent bumping of water contained in the evaporation cup.

  Other configurations and effects of the cooking device of the tenth embodiment are the same as those of the cooking device of the first embodiment.

(Eleventh embodiment)
FIG. 29 is a diagram showing an entire evaporating cup and evaporating cup locking mechanism included in the cooking device as an eleventh embodiment of the present invention.

  As shown in FIG. 29, the evaporating cup 206 provided in the cooking device of the eleventh embodiment is different from the evaporating cup 200 of the first embodiment in that a recess 224 is formed on the upper surface of the lid 220b.

  An outer container 180 for accommodating the evaporating cup 206 is disposed in the main body of the cooking device of the eleventh embodiment. The configuration of the outer container 180 is substantially the same as that of the ninth embodiment, and is different in that a hole is formed on the upper surface.

  The evaporation cup 206 is accommodated in the outer container 180 when attached to the main body 100 (FIG. 1) of the heating cooker 1. The thermistor 182 is disposed in the outer container 180 as temperature detecting means for detecting the temperature of the evaporation cup 206. The thermistor 182 is in contact with the outer wall surface of the cup part 210 of the evaporation cup 206 accommodated in the outer container 180 and detects the temperature of the cup part 210.

  A lock rod 273 is inserted into the recess 224 of the lid portion 220b of the evaporation cup 206 from the outside as a container fixing member through a hole formed in the upper surface of the outer container 180. Since the lock rod 273 is inserted into the hole of the outer container 180, it can be moved only in the vertical direction. A motor 271 is disposed outside the outer container 180 as a drive unit for moving the lock rod 273. The motor 271 is disposed such that the shaft extends in the horizontal direction. The lock rod 273 is attached to a cam 272 connected to the motor 271 by a support member 274 at a position off the center of the cam 272. When the motor 271 is driven, the cam 272 rotates and the support member 274 rotates in a circle within a circle so that the lock rod 273 moves up and down.

  FIG. 30 is a block diagram showing a control-related configuration according to the cooking device of the eleventh embodiment of the present invention.

  As shown in FIG. 30, the cooking device of the eleventh embodiment includes a control unit 190. The thermistor 182 detects the temperature and transmits a signal to the control unit 190. In this embodiment, the thermistor 182 transmits a signal to the control unit 190 when detecting that the temperature of the evaporation cup 206 is 60 ° C. or higher. The control unit 190 transmits a control signal to the motor 271.

  FIG. 31 is a diagram (A) showing a state where the evaporation cup is locked and a state (B) where the evaporation cup is not locked, with respect to the evaporation cup locking mechanism.

  As shown in FIG. 31A, when the temperature of the evaporation cup 206 is 60 ° C. or higher, the control unit 190 locks the lock rod 273 so that it fits into the recess 224 of the lid 220b of the evaporation cup 206. The motor 271 is controlled so as to move the rod 273 downward.

  When the lock rod 273 is fitted in the recess 224 of the lid portion 220b of the evaporation cup 206, the lock rod 273 comes into contact with the peripheral wall of the recess 224 even if the evaporation cup 206 is pulled out from the outer container 180. I can't.

  As shown in FIG. 31B, when the thermistor 182 does not detect that the temperature of the evaporation cup 206 is 60 ° C. or higher, the lock rod 273 does not fit into the recess 224 of the lid portion 220b of the evaporation cup 206. As described above, the control unit 190 controls the motor 271 so that the lock rod 273 is pulled upward.

  When the lower end of the lock bar 273 is pulled up above the lid 220 b of the evaporation cup 206, the evaporation cup 206 can be pulled out of the outer container 180.

The locking mechanism is not limited to the one using the motor 271, and for example, the evaporative cup 206 may be locked at a predetermined temperature or higher by using the recovery force of the shape memory alloy.

  As described above, the cooking device of the eleventh embodiment includes the lock rod 273 for fixing the evaporation cup 206 to the outer container 180 and the motor 271 for moving the lock rod 273. When the temperature of the evaporating cup 206 is equal to or higher than a predetermined temperature, the lock bar 273 is moved to a position where the evaporating cup 206 is fixed to the main body.

  By doing so, it is possible to prevent the user from removing the evaporation cup 206 from the outer container 180 when the evaporation cup 206 is at a predetermined temperature or higher.

  Other configurations and effects of the cooking device of the eleventh embodiment are the same as those of the cooking device of the first embodiment.

  The embodiment disclosed above should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above embodiments but by the scope of claims, and includes all modifications and variations within the meaning and scope equivalent to the scope of claims.
