  A control chamber 1000 is mounted on the protruding portion 1320, and a plurality of pins for fixing the control chamber 1000 are provided so as to stand upward. The heat shield plate 1300 is for suppressing heat from the heating chamber 300 from being transmitted to the control chamber 1000.

  The heat insulating plate 1200 is fixed by mounting the mounting portion 1210 on the fixing portion 1310 of the heat shield plate 1300, for example, by bolts / nuts or screws. The heat insulating plate 1200 is configured using, for example, aluminum, a galvanized steel plate, an aluminized steel plate, a galvalume steel plate, or the like.

  As shown in FIG. 13, a motor chamber 200 is provided in the upper part of the housing 100. A duct 210 is provided in the motor chamber 200. The duct 210 is made of, for example, a resin material having high heat resistance. A motor 220 for rotating the cooling fan 230 and the circulation fan 660 is provided on the duct 210. As the motor 220, a scraping motor is used. However, the motor 220 is not limited to a scraping motor, and a motor other than the scraping motor, for example, a DC (Direct Current) fan motor may be used.

  As shown in FIG. 13, a first opening 211 for communicating the inside and the outside of the duct 210 is provided at the approximate center of the duct 210.

  An air supply port 140 is provided above the back surface of the housing 100 so as to communicate with the motor chamber 200. The air supply port 140 is made up of a large number of small-diameter holes and supplies the outside air into the motor chamber 200.

  An exhaust port 150 is provided below the air supply port 140 on the back surface of the housing 100 so as to communicate with the motor chamber 200. The exhaust port 150 is composed of a large number of small-diameter holes, and is used to exhaust the air in the motor chamber 200 to the outside.

  The motor 220 is provided so that the motor coil 221 is positioned on the air inlet 140 side. As a result, the air supplied from the air supply port 140 into the motor chamber 200 is surely in contact with the motor coil 221, so that the cooling efficiency of the motor coil 221 can be increased.

  Below the duct 210, a cooling fan 230 that is rotated by the power of the motor 220 is provided. The cooling fan 230 is attached to the rotating shaft of the motor 220. The cooling fan 230 takes in the outside air from the air supply port 140 into the motor chamber 200 and causes the air in the motor chamber 200 to flow so that the air in the motor chamber 200 is discharged from the exhaust port 150. The motor 220 is cooled by the flow of air by the cooling fan 230, and overheating of the motor 220 can be prevented. The overheating of the motor 220 may be due to the heat generated in the motor 220 itself, or the heat in the heating chamber 300 may be transmitted to the motor 220 through the shaft of the motor 220.

  The duct 210 is connected to the exhaust port 150. Air that flows into the motor chamber 200 from the air supply port 140 is sucked by the cooling fan 230 and flows into the duct 210 through the first opening 211. The air is then discharged from the exhaust port 150 through the duct 210.

  A substantially rectangular second opening 213 is formed on the exhaust port 150 side of the duct 210. The second opening 213 communicates with the exhaust port 150, and the air in the motor chamber 200 is exhausted from the exhaust port 150 through the second opening 213 of the duct 210. The diameter of the cooling fan 230 and the width of the second opening 213 may be substantially equal, or the width of the second opening 213 may be greater than the diameter of the cooling fan 230. Thereby, the air blown out toward the exhaust port 150 by the cooling fan 230 can be smoothly discharged from the exhaust port 150 through the second opening 213.

  The cooling fan 230 is provided at a position substantially the same height as the exhaust port 150. Thereby, since the air discharged by the rotation of the cooling fan 230 is discharged from the exhaust port 150 at the shortest distance without being obstructed by anything, the flow efficiency of air in the motor chamber 200 can be improved.

  Furthermore, the housing 100 is also cooled by causing the air in the motor chamber 200 to flow. Thereby, it can prevent that a user touches the housing | casing 100 and is burned during cooking. In addition, it is possible to prevent a situation in which an article cannot be placed on the housing 100.

  Inside the rectangular box-shaped casing 100 of the heating cooker 10, a heating chamber 300 configured in a hollow box shape with the front surface being an opening 310 is provided. The opening 310 is opened and closed by the door 130. The heating chamber 300 is a space defined by a ceiling wall 301, a bottom wall 302, a left side wall 303, a right side wall 304 and a back wall 305. The bottom wall 302 is made of a metal having excellent light reflectivity, such as an aluminum-plated steel plate or stainless steel, and functions as a reflecting plate that reflects the heat of the oven heater. However, the metal which comprises the bottom wall 302 is not restricted to them, What kind of thing may be used if it is a metal material with good light reflectivity.

  As shown in FIGS. 13 and 14, a placement net 320 is provided below the heating chamber 300. In FIG. 14, for convenience of explanation, the ceiling wall 301, the left side wall 303, the right side wall 304, the back wall 305, the upper hood 610 and the lower hood 620 of the heating chamber 300 are omitted. The placement net 320 is a net made of a metal wire. A square dish 400 can be placed on the placing net 320.

  In addition, it is not restricted to the mounting net | network 320, By providing the left-right paired rail extended from the front of the heating chamber 300 to the back, and supporting the both ends of the square plate 400 with a rail, the square plate 400 floated from the bottom wall 302. You may make it hold | maintain in a state. The placement net 320 may be configured to move back and forth in conjunction with opening and closing of the door 130.

  The square dish 400 is configured in a bottomed rectangular box shape having an open top from a flat bottom surface portion 401 and a side surface portion 402 rising in a curved shape from the outer periphery of the bottom surface portion 401. Although described in detail later, the shape of the side surface portion 402 is to make it easier for hot air descending in the heating chamber 300 to be directed toward the center of the square dish 400. In addition, a flange 403 extending in the horizontal direction is formed on the entire peripheral edge of the square plate 400, and has a size for blocking the flow path of hot air below the flange 403 in the heating chamber 300. Yes. A breathable top plate member 410 is detachably provided on the opening side of the square plate 400.

  The top plate member 410 is configured as a net-like member having a size that fits the inner peripheral edge of the flange 403. The material to be cooked may be placed directly on the top surface of the top plate member 410. Since the top plate member 410 is configured in a net shape having a ventilation gap, the hot air blown down can pass through the top plate member 410 and enter the square plate 400. Thereby, it becomes possible to heat the to-be-cooked material mounted on the top plate member 410 from below with hot air. It is also possible to place the material to be cooked directly on the square plate 400.

  The square plate 400 may be integrally formed of a high heat-resistant resin such as glass reinforced PPS resin, glass reinforced PBT resin, polyimide resin, or the like, or may be formed of sheet metal to have a fluorine coat finish or enamel finish. Furthermore, you may manufacture with heat-resistant tempered glass, ceramics, etc.

  When hot-air circulating cooking is performed by the heating cooker 10, the square dish 400 provided with the top plate member 410 is placed on the placement net 320, and the material to be cooked is placed on the top plate member 410. Moreover, when performing oven cooking, a to-be-cooked material is directly mounted on the square plate 400 except for the top plate member 410. Further, when the cooking device 10 is used as an oven toaster, the material to be cooked is placed directly on the placing net 320. When the cooking device 10 is used as an oven toaster, an oven toaster dish different from the square dish 400 may be placed on the placement net 320.

  The space below the square plate 400 of the heating chamber 300 is closed by placing the square plate 400 on the placement net 320 during the hot-air circulating cooking that is the first cooking mode. The inside can be narrowed. As a result, hot air does not circulate in the entire area of the heating chamber 300, but hot air circulates in a space above the square plate 400, so that heating efficiency is increased and the temperature in the heating chamber 300 is likely to rise. Become. Thereby, shortening of heating time, reduction of power consumption, etc. can be aimed at.

  Two upper oven heaters are provided above the heating chamber 300 so as to extend between the left side wall 303 and the right side wall 304. Further, two lower oven heaters are provided below the heating chamber 300 so as to extend between the left side wall 303 and the right side wall 304. The configurations of the upper oven heater and the lower oven heater will be described later.

  Above the upper oven heater in the heating chamber 300, a fly heater 500 is provided. The frying heater 500 is a heater that operates in hot air circulation cooking, which is the first cooking mode. In the first cooking mode, the heating cooker 10 circulates the air heated by the frying heater 500 in the heating chamber 300 at high speed, thereby cooking fried food such as French fries and fried chicken without using oil. Mode. For example, the fly heater 500 can circulate hot air of about 80 to about 200 degrees in the heating chamber 300.

  The fly heater 500 is connected to the operation board 1040 and the power supply board 1050. When performing hot air circulation cooking that is the first cooking mode, the user presses the cooking mode switching button of the operation unit 110 and sets the cooking mode to hot air circulation cooking. Furthermore, the user designates the temperature necessary for cooking with the temperature setting button, and designates the time necessary for cooking with the heating time setting button. The microcomputer of the power supply board 1050 energizes the fly heater 500 to turn it on according to the input content from the user to the operation unit 110, and controls the temperature and heating time of the fly heater 500.

  As shown in FIG. 14, the fly heater 500 is configured as a spiral sheathed heater distributed in a plane and having a ventilation gap. The spiral sheathed heater has an advantage that a high heat capacity can be obtained because it has a ventilation gap and does not block the flow of hot air and has a large surface area. In addition, the sheathed heater has an advantage that it emits much far infrared rays, although its rise as a heat source is inferior to that of a quartz tube heater.

  A circular dish-shaped upper hood 610 and a lower hood 620 are provided above the fly heater 500 and below the duct 210. The upper hood 610 and the lower hood 620 have curved side surfaces and are provided so as to open downward. The upper hood 610 and the lower hood 620 are made of metal such as an aluminized steel plate.

  A space between the upper hood 610 and the lower hood 620 functions as an air flow path 630 that is a flow path for hot air. A suction port 640 for sucking hot air in the heating chamber 300 into the air flow path 630 is provided in the approximate center of the lower hood 620. Further, the outer edge portion of the air flow path 630 functions as a blowout port 650 that blows hot air into the heating chamber 300. The outlet 650 is configured in an annular shape. Further, a circulation fan 660 is provided in the air flow path 630 substantially in parallel with the fly heater 500. Circulation fan 660 is attached to the rotating shaft of motor 220.

  Due to the rotation of the circulation fan 660 by the power of the motor 220, the air in the heating chamber 300 is sucked up to the circulation fan 660 side. At that time, the air is heated by the fly heater 500 by passing through the ventilation gap of the fly heater 500. The air heated by the fly heater 500 is sucked into the air flow path 630 from the suction port 640 of the lower hood 620 (arrow A in FIG. 13). Then, the air sucked into the air flow path 630 is blown into the heating chamber 300 as hot air from the outlet 650 at the outer edge of the air flow path 630 in the centrifugal direction by the rotation of the circulation fan 660 (FIG. 13). Arrow B).

  The hot air blown out from the outlet 650 by the circulation fan 660 descends in the heating chamber 300 (arrow C in FIG. 13), and along the side surface portion 402 of the curved square plate 400, the bottom surface of the square plate 400 In the space between the portion 401 and the top plate member 410, it flows toward the center of the square plate 400. When hot air enters the square plate 400, the cooking material placed on the top plate member 410 can be heated from below.

  The hot air is sucked upward in the square plate 400 by the circulation fan 660 (arrow D in FIG. 13), heated again by the fly heater 500, and sucked into the air channel 630 from the suction port 640 (arrow A). ). When the heating cooker 10 operates in the first cooking mode, this circulation of hot air (arrows A to D in FIG. 13) is continuously repeated.

  Since the circulation fan 660 rotates, the hot air can be circulated efficiently by configuring the fly heater 500 in a circular shape and the blowout port 650 in an annular shape.

  Further, since the hot air is blown out almost directly from the blowout port 650, the hot air can be circulated efficiently by positioning the side surface portion 402 of the square plate 400 at a position almost directly below the blowout port 650.

  A hood cover 670 is provided on the upper hood 610 with a slight gap. The hood cover 670 is formed in a shape substantially the same as the upper hood 610. The hood cover 670 is made of a heat insulating material such as a stainless steel plate. The hood cover 670 functions as a partition member for preventing heat from the heating chamber 300 from being transmitted to the motor chamber 200. By providing a hood cover 670 with a gap between it and the upper hood 610, the heat insulation effect is further enhanced.

  Two upper oven heaters are provided above the heating chamber 300 so as to extend between the left side wall 303 and the right side wall 304. The upper oven heater located on the opening 310 side of the heating chamber 300 is referred to as a first upper oven heater 711, and the upper oven heater located on the back wall 305 side is referred to as a second upper oven heater 712.

  Further, two lower oven heaters are provided between the left side wall 303 and the right side wall 304 so as to be positioned below the heating chamber 300 and below the square plate 400. The lower oven heater located on the opening 310 side of the heating chamber 300 is referred to as a first lower oven heater 721, and the lower oven heater located on the back wall 305 side of the housing 100 is referred to as a second lower oven heater 722.

  The oven heater is a heater that operates in the second cooking mode and generates radiant heat when energized. In the second cooking mode, the cooking device 10 functions as a so-called oven that heats the material to be cooked by the heat of the heater.

  The oven heater is connected to the operation board 1040 and the power supply board 1050. When performing cooking in the second cooking mode, the user operates the cooking mode switching button of the operation unit 110 to set the cooking mode to oven cooking. Further, the user designates the temperature necessary for cooking with the temperature setting button 112 and designates the time necessary for cooking with the heating time setting button 113. The microcomputer on the power supply board 1050 energizes the oven heater to turn it on according to the input content from the user to the operation unit 110, and controls the temperature and heating time of the oven heater.

  The heater for the upper oven and the heater for the lower oven are composed of, for example, a quartz tube heater. The quartz tube heater emits far infrared rays, but the amount generated is inferior to that of the sheathed heater. However, since it quickly rises as a heat source, it is suitable as a heat source for an oven. In addition, the number of the heaters for upper ovens and the heaters for lower ovens is an illustration to the last, and the number is not limited to two each.

  A reflector 800 is provided on each of the first upper oven heater 711 and the second upper oven heater 712.

As a result, the interior lamp 1500 is turned off when the door 130 is opened. In the state where the door 130 is opened, the state of the material to be cooked can be confirmed by the illumination in the heating chamber 300. Therefore, power can be saved by turning off the interior lamp 1500.

  Since the bottom surface of the housing 100 is configured to open, the bottom surface of the heating chamber 300 is open. As shown in FIGS. 3, 4, 13, and the like, a thin box-shaped tray support 1600 that opens forward is provided on the bottom surface side of the housing. The tray 1700 is provided below the bottom surface of the housing by being placed on the tray support portion 1600. The tray 1700 is configured using, for example, an aluminum galvanized steel plate. The tray 1700 can be pulled out in the forward direction (side on which the door is provided) by sliding on the tray support portion 1600.

  The tray 1700 is configured to have a first recess 1710 that is recessed downward, and two second recesses 1720 that are provided in the rear of the first recess 1710. The second depression 1720 is formed so as to be recessed deeper than the first depression 1710. Further, the front end of the tray 1700 is configured as a drawer handle 1730 by being bent downward.

  As described above, the bottom of the heating chamber 300 is opened because the bottom surface of the housing 100 is opened. Therefore, a piece of cooking material, oil, moisture, etc. that is placed on the placement net 320 and cooked in the heating chamber 300 is accumulated in the tray 1700 when it falls from the placement net. Then, by pulling the drawer handle 1730 and periodically pulling the tray 1700 forward and removing it from the heating cooker 10, pieces of cooking material, oil, moisture, etc. on the tray 1700 can be easily removed by washing. it can.

  In addition, when pulling out tray 1700, there exists a possibility that the piece of to-be-cooked material on the tray 1700 may be caught in the edge of the bottom face of the heating cooker 10, etc. Since the tray 1700 is being pulled out, a piece of the material to be caught that has been caught moves to the rear of the tray 1700. A piece of the cooking material that has moved rearward falls to a second depression 1720 that is deeper than the first depression 1710. Thereby, it can prevent that the piece of to-be-cooked material falls from the tray 1700. For this reason, the second recess 1720 is formed on the rear side in the depth direction of the tray 1700.
