JP 2001-137121 A

The steamer insole disclosed in Patent Document 1 can heat food placed on the insole with steam, but it only heats the food with steam and is not capable of heating the food while stirring it.

The present invention was conceived in light of the above problems, and provides a cooking device (hereafter referred to as a "steam-heated rotating machine") that can process food by breaking, crushing, stirring, etc. using blades while heating it with steam.

Specifically, the steam heating rotary machine of the present invention has the following features:
A container into which the raw materials are introduced;
A blade rotating within the vessel;
A motor for rotating the blade;
A water tank capable of storing water;
a water supply pipe connected from the water tank to the inside of the container;
a pump for pumping water from the water tank through the water supply pipe;
a heater capable of simultaneously heating the water supply pipe and the container;
The pump is characterized by having a controller that controls the motor, the pump, and the heater.

The steam heating rotary machine of the present invention heats water in a water tank and supplies it as warm water, boiling water or high-temperature steam to the ingredients (food) in a container, and can process the ingredients by breaking, crushing, pulverizing, stirring and kneading them with blades. In other words, the ingredients can be made into a paste without burning them. For example, soybeans can be boiled and processed while being steam heated, making it ideal for processing grains. It can be particularly well suited for use in making soy meat using soybeans as the raw material.

The production of soy meat requires the process of making dried soybeans absorb water using hot water and then steaming the soybeans in the container using steam, but the steam heating rotary machine of the present invention uses a heater that is used both to heat the container and to generate steam. This allows for effective steaming while maintaining the temperature of the bottom of the container, and also allows for the moisture content of the soy meat to be regulated. In addition, because the container is heated and the steam is generated using a single heater, the steam heating rotary machine can be constructed in a compact configuration.

In the steam heating rotary machine, the water tank is equipped with a water level gauge in the above configuration. This allows the amount of water required for processing the raw materials to be accurately measured, preventing water shortages and excesses. This steam heating rotary machine therefore does not require a drainage system, which contributes to a more compact configuration of the entire device.

In addition, in the above configuration, this steam heating rotary machine can change the amount of water fed by the pump. This configuration eliminates the need to adjust the heater temperature for the generation of hot water, boiling water, and steam. Specifically, to increase the temperature of the water supplied to the container, the amount of water fed is reduced, and to decrease the temperature of the water supplied to the container, the amount of water fed is increased. This configuration eliminates the need to control the heater temperature using PID, makes it easier to adjust the temperature of the water supplied to the container, and reduces the amount of water wasted.

In addition, in the above configuration, this steam heating rotary machine rotates the blades intermittently while steam is being supplied into the container. When heating with steam, a temperature difference occurs between the parts that are directly hit by the steam and those that are not, but by rotating the blades intermittently, the steam can be applied evenly to the entire raw material, achieving uniform heating. In addition, since the container is also heated while steam is being released, the intermittent operation of the blades also helps prevent the raw materials from burning.

In addition, in the above configuration, the steam heating rotary machine can energize the heater without supplying water. By energizing the heater without supplying water in this way, the amount of heat that can be used to heat the container increases, and a higher amount of heat can be supplied to the container. Therefore, it can also be used as a regular heating cooker for cooking soup dishes, etc.

In addition, in the above configuration, the steam heating rotary machine has a kneading blade that removes the crushed material that has been attached to the inner wall of the container. This kneading blade removes the crushed raw material that has been attached to the inner wall of the container and drops it, allowing for more uniform mixing.

Below, an embodiment of the present invention will be described with reference to the drawings. In the following description, "up" refers to the direction upward in the direction of gravity, and "down" refers to the opposite direction.

Figure 1 shows the configuration of a steam heating rotary machine 1 according to the present invention. Figure 2 shows a partial cross section of one embodiment of the steam heating rotary machine 1. Figure 3 shows a perspective view from below of Figure 2, and Figure 4 shows a perspective view of only the heater and water pipes at the bottom of the container in Figure 3. Some parts of the configuration shown in Figure 1 are omitted in Figures 2 to 4. Conversely, some parts in Figures 2 to 4 are not disclosed in Figure 1. Below, the configuration of the steam heating rotary machine 1 will be explained mainly with reference to Figure 1, but also with reference to Figures 2 to 4. The steam heating rotary machine 1 has a power supply unit not shown in Figures 1 to 4, and power is supplied to the necessary locations as appropriate.

The steam heating rotary machine 1 is composed of a container 10, a lid 12, a water tank 14, and a mechanism 16. The mechanism 16 includes a heater 20, a heat conductor 22, a motor 24, a pump 26, and a controller 28. Note that part of the mechanism 16 is omitted in FIG. 2. A water supply pipe 30 extends from the water tank 14 to the lid 12. Note that the water supply pipe 30 may be configured to be disconnected midway when the lid 12 is removed or attached.

A rotating shaft 32 is installed inside the container 10. A blade 34 and a mixing blade 36 are attached to the rotating shaft 32. The rotating shaft 32 also extends into the lid 12, and a stirring blade 38 arranged in the lid 12 is also connected to the rotating shaft 32. Each element is described in detail below.

The container 10 is a vessel having a bottom surface 10b and a side wall 10s, into which ingredients (food to be cooked) are poured and processed. It is open at the top. The shape of the container 10 is not particularly limited, but a circular cross section is preferable since there is a rotor (kneading blade 36) that rotates along the side wall 10s. The cross section of the upper and lower parts of the container 10 may be different in size. The bottom surface 10b can be heated. For ease of cleaning, it is preferable that the container 10 is configured so that the mechanism 16 and the lid 12 can be detached.

A rotating shaft 32 is provided in the center of the container 10, and a blade 34 is fixed to the rotating shaft 32. The blade 34 is preferably shaped like a sword with a blade side and a ridge side, but both may be blades. The rotating shaft 32 has through holes 40d and through holes 40u (hereinafter, when both through holes are referred to collectively, they will be called "through holes 40") formed at the bottom and top, and steam or hot water is discharged from these through holes 40. In FIG. 2, there are four through holes 40d, two at the top and two at the bottom, below the rotating shaft 32, and the blades 34 are arranged above and below the through holes 40d. In addition, a through hole 40u is provided above the rotating shaft 32. In this way, there may be multiple through holes 40 and blades 34.

Referring to FIG. 1, a kneading blade 36 is connected to the rotating shaft 32 at the top of the container 10. The kneading blade 36 comes into contact with the side wall 10s of the container 10 to scrape off (strip off) crushed material adhering to the side wall 10s, thereby processing the input raw materials as uniformly as possible.

The bottom surface 10b of the container 10 is formed from a material with high thermal conductivity (mainly a metal material). The inner bottom surface 10ba of the bottom surface 10b of the container 10 is formed flat, while the outer bottom surface 10bb is formed in a shape that slopes from the center toward the side wall 10s. The bottom surface 10b of the container 10 is heated by the heat from the heater 20 arranged under the container 10, and the temperature of the bottom surface 10b increases. The slope of the outer bottom surface 10bb of the container 10 is to ensure contact with the heater 20.

A lid 12 is placed on top of the container 10. The lid 12 is hollow and has a certain thickness in the vertical direction, and ingredients can be placed inside. The ingredients are additives added when the raw materials are processed, and may be not only seasonings such as salt, pepper, soy sauce, and oil, but also aromatic vegetables, fruits, grains, and even meat and fish.

The lid 12 is also provided with an agitating blade 38 for mixing the ingredients. The agitating blade 38 comes close to (or touches) the bottom surface of the lid 12, agitates the ingredients set in the lid 12, and also pours them into the container 10. The agitating blade 38 is fixed to a rotating shaft 32L inside the lid 12. The bottom surface of the lid 12 is also provided with an ingredient inlet 12h for pouring ingredients into the container 10. The ingredient inlet 12h is closed by an ingredient inlet lid 12hL, and when the ingredients are poured in, the ingredient inlet lid 12hL moves and opens the ingredient inlet 12h. The ingredient inlet lid 12hL is opened and closed by a method using a motor and a magnet. This opening and closing can be performed by an instruction signal Cc from the controller 28 described later.

The rotating shaft 32L inside the lid 12 is fitted with the rotating shaft 32 to which the connecting blade 36 is fixed, and as the rotating shaft 32 rotates, the connecting blade 36 and the stirring blade 38 rotate in sync. On the other hand, the part where the blade 34, the connecting blade 36, and the stirring blade 38 are connected is connected by a one-way clutch 42 (see Figure 2). In other words, when the rotating shaft 32 rotates in one direction, only the blade 34 rotates, and no rotational force is transmitted to the connecting blade 36 and the stirring blade 38. When the rotating shaft 32 rotates in the opposite direction, the blade 34, the connecting blade 36, and the stirring blade 38 can rotate. With this configuration, three types of rotating bodies (effectively two types), the blade 34, the connecting blade 36, and the stirring blade 38, can be rotated separately by one motor 24.

A mechanical unit 16 is provided below the container 10. The mechanical unit 16 includes a motor 24, a heater 20, a pump 26, and a controller 28. The motor 24 has a drive shaft 24D that fits with a rotating shaft 32. In other words, the drive shaft 24D of the motor 24 can rotate the rotating shaft 32. The motor 24 can rotate the drive shaft 24D in separate rotation directions to the left and right. The motor 24 can also change the rotation speed. The circuit for controlling the rotation direction and rotation speed of the motor 24 can be treated as the motor 24. The movement of the motor 24 is controlled by an instruction signal Cm from the controller 28.

The heater 20 is disposed below the container 10. It is desirable to form the heater 20 in a horseshoe shape so that the drive shaft 24D of the motor 24 passes through the center of the bottom surface 10b of the container 10 and heat can be applied as uniformly as possible. A thermal conductor 22 is disposed on the upper part of the heater 20. The thermal conductor 22 is made of a material with high thermal conductivity, and contacts the bottom surface 10b of the container 10 to transfer heat to the bottom surface 10b of the container 10. The thermal conductor 22 is provided with a temperature sensor 48, which notifies the controller 28 of the temperature of the thermal conductor 22 by a notification signal St. The temperature of the thermal conductor 22 can be regarded as the temperature of the outer bottom surface 10bb of the container 10.

In Figure 3, it can be seen that the horseshoe-shaped heater 20 and the water supply pipe 30 underneath are arranged around the opening 16H through which the drive shaft 24D of the motor 24 is inserted. Figure 4 shows only the heater 20 section.

Referring to FIG. 4, a thermal conductor 22 is shown surrounding the heater 20. The upper surface 22u of the thermal conductor 22 in FIG. 4 is inclined from the center toward the periphery, making it easier to come into contact with the inclination of the outer bottom surface 10bb of the container 10. The ON/OFF of the heater 20 is controlled by an instruction signal Ch from the controller 28.

Referring again to FIG. 1, a water tank 14 is provided next to the container 10. A water level gauge 46 is provided in the water tank 14, and notifies the controller 28 of the water level in the water tank 14 by a notification signal SL. With this configuration, the controller 28 can know how much water has been pumped into the container 10.

A water supply pipe 30 is arranged from the water tank 14 to the center of the lid 12. The water supply pipe 30 passes from below the water tank 14 through the pump 26 while making contact with the underside of the heater 20, then rises up the side wall 10s of the container 10 to reach the lid 12. Water from the water tank 14 passes through the center of the lid 12, through the rotating shaft 32, and is supplied into the container 10 through the through hole 40. In other words, the water supply pipe 30 receives heat from the heater 20 at its underside and is heated. The pump 26 is configured so that the water supply rate can be adjusted by an instruction signal Cp from the controller 28.

In Figure 3, the water supply pipe 30 from the water tank 14 is arranged along the heater 20 below the container 10 via the pump 26, and the portion that reaches the top of the container 10 can be seen. In Figure 2, the water supply pipe 30 is shown arranged in the center of the lid 12 from the back side of the page of the lid 12. Also, in Figure 4, the water supply pipe 30 is arranged along the underside of the heater 20.

On the underside of the heater 20, a cylindrical body formed to cover the periphery of the water supply pipe 30 is integrally formed with the thermal conductor 22, and the water supply pipe 30 portion can be considered a pipe heater. In other words, the thermal conductor 22 that transfers heat to the outer bottom surface 10bb of the container 10 and the pipe heater that heats the water supply pipe 30 are formed by the same heater 20. By configuring it in this way, it is possible to heat the inside of the container 10 and generate different water states such as hot water, boiling water, and steam with a single heater 20.

More specifically, if the water supply rate is reduced, a unit volume of water can receive heat from the heater 20 for a longer period of time, resulting in a higher temperature. By supplying water slowly, the water boils and evaporates in the heater 20, and the water turns into steam and is supplied to the container 10. By increasing the water supply rate, the state of the water produced can be changed between hot water and boiling water. If the heater 20 is turned OFF, the water supplied to the container 10 can be room temperature water.

It is assumed that the steam heating rotary machine 1 will often supply steam after supplying cold or hot water. Therefore, rather than a configuration that allows the temperature of the heater 20 to be set precisely, it is more efficient and simpler to simply switch the heater 20 on and off and adjust the temperature of the water supplied by the water supply rate.

The controller 28 is composed of an MPU (Micro Processor Unit), memory, and input/output devices. The input/output devices include an input section that transmits user operations to the controller 28, and a display section that shows the current state of the steam heating rotary machine 1. The controller 28 controls the operation of at least the motor 24, the pump 26, the ingredient insertion port 12hL, and the heater 20 using command signals Cm, Cp, Cc, and Ch, and can detect the water level in the water tank 14 and the temperature of the heater 20 using notification signals SL and St from the water level gauge 46 and the temperature sensor 48. The controller 28 includes a timer inside.

<Explanation of operation>
Next, the operation of the steam heating rotary machine 1 will be described. The steam heating rotary machine 1 has three basic controls: heater control, pump control, and motor control. These controls are executed by the above-mentioned elements and the controller 28. Here, the explanation will be given on the assumption that these basic controls are supplied as subroutines.

FIG. 5 shows the process flow of heater control. A set of processes (subroutines) for heater control is represented as "Heater (COMT, T _H )." For heater control, a parameter COMT indicating ON/OFF and T _H indicating the time for turning the heater ON are specified. The parameter COMT is specified with three values: "ON,""OFF," or "CONT.""ON" indicates that electricity is supplied to the heater 20 for the time specified by the following parameter T _H , and "OFF" indicates that electricity is cut off. "CONT" means that electricity is continued to be supplied to the heater 20 until a signal equivalent to "OFF" is received.

When heater control is initiated (step S300), power is applied to the heater 20 (step S302). In this step, the temperature of the heater 20 increases.

Next, it is determined whether the power supply time is "cont". The parameter _TH is specified as either the power supply time Ht (specific power supply time) or the parameter "cont". "cont" maintains power supply to the heater 20 until a signal equivalent to an "OFF" signal is received. It is determined whether the power supply time is "cont" (step S304).

If it is not "cont" (N branch of step S304), the state is maintained until the energization time _TH reaches the designated energization time Ht (step S306). If the energization time is "cont" in step S304 (Y branch of step S304), the state is maintained until the parameter COMT becomes "OFF" (step S308).

If the conditions of steps S306 and S308 are met (Y branch of each step), the heater 20 is turned off (step S310), and the heater control process ends (step S312). For example, the process returns to the main routine from which the subroutine is called.

FIG. 6 shows the process flow of the pump control. The pump control process (subroutine) is represented as "pump (Q, T _P )". The pump control has two parameters, the water supply rate "Q" and the water supply time "T _P ". When the pump control starts (step S350), water supply is started at the water supply rate Qs (step S352). The temperature of the water flowing through the water supply pipe 30 and supplied to the container 10 is determined by the water supply rate. Next, water is supplied at the same water supply rate until the water supply time T _P reaches a specified specific value Pt (step S354).

When the water supply time T _P reaches the time Pt, the water supply is stopped (step S356), and the pump control process is terminated (step S358).

FIG. 7 shows the process flow of motor control. A complete process (subroutine) of motor control is represented as "Motor (ω, R _T )". Motor control has two parameters, the rotation speed "ω" and the rotation time "R _T ". When motor control starts (step S400), the motor 24 is rotated at the rotation speed ωa (step S402). At this time, the rotation speed "ω" can take positive or negative values. A positive value of the rotation speed is forward rotation, in which only the blade 34 rotates. A negative value of the rotation speed is reverse rotation, in which the blade 34, the connecting blade 36, and the stirring blade 38 rotate together.

Next, rotation is maintained until the rotation time reaches a specifically specified value (time) Mt (step S404), and when the rotation time reaches Mt (Y branch of step S404), rotation of the motor 24 is stopped (step S406), and the motor control process is terminated (step S408).

As described above, the steam heating rotary machine 1 can prepare a cooking course program according to a recipe by combining three types of control: heater control, pump control, and motor control.

Below is an example of a cooking process for soy meat using soybeans as the raw material. Soy meat can be made by steaming soybeans and then finely grinding them.

Figure 8 shows an example of the soy meat manufacturing process. Before starting the steam heating rotary machine 1, a specified amount of soybeans is placed in the container 10, the lid 12 is closed, and ingredients such as salt, sugar, olives, etc. are placed in the lid 12. When the soy meat manufacturing course starts (step S100), a specified amount of hot water is supplied into the container 10. The hot water causes the soybeans, the raw material, to absorb the water (step S102).

In this process, the heater 20 is turned ON by the heater (ON, CONT), and the pump 26 is operated by the pump (Q1, T _P 1) to send water at a water sending rate Q1 for T _P 1 second. The water sending rate Q1 at this time is a water sending rate at which hot water of about 60°C is supplied to the container 10 by the heater 20. The amount of hot water supplied to the container 10 is accurately calculated by multiplying the water sending rate Q1 by the supply time T _P 1 second. Then, when the supply of a predetermined amount of hot water has been completed, the supply of electricity to the heater 20 is stopped by the heater (OFF, CONT).

The steam heating rotary machine 1 according to the present invention does not have a drainage system mechanism, so the amount of hot water initially supplied must be measured accurately, and it is therefore useful to be able to accurately calculate the amount of hot water supplied as described above. Also, instead of supplying water to the container 10 and then heating the entire container 10, hot water at a predetermined temperature can be supplied from the start.

Next, the steaming process is performed. In the steaming process, the heater 20 (ON, T _H 2) is turned ON for T _H 2 seconds. Then, the pump (Q2, T _P 2) supplies water at a water supply rate Q2 for T _P 2 seconds. Here, the water supply rate Q2 is a water supply rate at which the water supplied to the container 10 turns into steam. The heating time T _H 2 seconds of the heater 20 and the water supply time T _P 2 of the pump 26 may be the same. By these two subroutines, steam is supplied into the container 10 for T _P 2 seconds, and the steaming process by steam heating is performed. During this time, the container 10 itself is also heated by the heater 20 (step S104).

By repeating this state maintenance for Tint seconds and motor (ω1, R _T 1) during this steam supply, the blade 34 rotates at the rotation speed ω1 for R _T 1 seconds every Tint seconds. In other words, the blade 34 operates intermittently during steam heating. This operation allows the ingredients to be steamed uniformly. Here, N times represents an integer number equal to 1 or greater. Furthermore, if Tint seconds and R _T 1 second are repeated N times, this is equal to T _H 2 seconds (or T _P 2 seconds).

Next, in the pulverization process, the heater 20 is energized for T _H 3 seconds by the heater (ON, T _H 3). During this time, the motor (ω2, R _T 2) and the motor (-ω3, R _T 3) rotate the motor forward at a rotation speed of ω2 for R _T 2 seconds and reverse at a rotation speed of ω3 for R _T 3 seconds, and this process is repeated M times. In other words, only the blade 34 is rotated at high speed in the forward direction, and the blade 34, the connecting blade 36, and the stirring blade 38 are rotated slowly in the reverse direction. The raw material is pulverized by the high-speed rotation of only the blade 34, and the connecting blade 36 and the stirring blade 38 are also rotated slowly together, thereby scraping off the pulverized powder adhering to the side wall 10s of the container 10 (step S106).

In addition, an instruction is given to open the ingredient insertion lid 12hL during the repeated operation of the motor 24. This can be done by an instruction signal Cc. In this way, the ingredients can be added to the raw materials while scraping off the crushed powder adhering to the side wall 10s of the container 10, and the raw materials can be crushed and the crushed raw materials and ingredients can be mixed.

The timing of adding the ingredients is not particularly limited, but it is preferable to add them when the grinding has progressed to a certain extent. Also, the values of ω2 and -ω3 (forward and reverse rotation speeds) may be changed as the grinding progresses.

As described above, the soy meat production recipe can be implemented by combining the control of three elements: the heater 20, the pump 26, and the motor 24.

Next, an example of the process flow for a cooking mode that can heat and stir liquids such as soup is shown in Figure 9. When this flow starts (step S200), the system waits for input (step S202). When there is an input from the user (Y branch in step S202), it is determined whether the input is an instruction for "end," "heater ON," "heater OFF," "motor ON," or "motor OFF." If the input is "end" (Y branch in step S204), the process ends (step S206).

If the input is "Heater ON" (step S208), the heater (ON, CONT) is executed (step S210). The heater (ON, CONT) is a process that simply energizes the heater 20 without determining the power supply time.

If the input is "Heater OFF" (step S212), HEATER (OFF, CONT) is executed (step S214). HEATER (OFF, CONT) is a process that cuts off the power supply to the heater 20.

If the input is "MOTOR ON" (step S216), MOTOR (ω4, R _T 4) is executed (step S218). MOTOR (ω4, R _T 4) is a process for rotating the motor 24 at the rotation speed ω4 for R _T 4 seconds to rotate the blade 34. In this case, the rotation speed ω4 is preferably a rotation speed sufficient for slowly stirring soup or the like.

If the input is "Motor OFF" (step S220), motor (0,0) is executed (step S222). Motor (0,0) is a process that sets the rotation speed to zero and stops the motor 24.

As described above, in this cooking mode, the heating (heater 20) for the container 10 can be turned on/off, and the rotation speed of the motor 24 can be controlled independently to zero or ω4.

The steam heating rotary machine of the present invention can be suitably used as a cooking device for steam heating at home. It is particularly effective in producing soy meat as a meat substitute.
