Abstract

PURPOSE:To obtain the cooker having both functions of a general gas range and a rice cooking range by a method wherein a magnet is permitted to be attracted to a ferrite only when a thermoswitch is sunk by a given scale and a gas circuit, communicating the cock of the instrument and a rice cooking valve, is opened by the magnet. CONSTITUTION:When a lever 16 is pushed down, a magnet rod 20 and the magnet 22 are pushed up by a part 19 of the lever through a magnet rod spring 21. At this time, the thermoswitch 5 is being pushed down by a scale (a) at the recess 28 of the central part of the bottom of an exclusive pot 27 for rice cooking and the magnet 22 arrives at the ferrite 23, therefore, the magnet is attracted to the ferrite 23 and the rice cooking valve 15 is opened. When heating for cooking the rice is finished, the temprature of the ferrite 23 arrives at the Curie point of the ferrite 23, the attraction of the magnet 22 to the ferrite 23 is released by the repulsive force of the valve spring 28 for the rice cooking valve 15 and the gravity of the lever 16 and the magnet 22 is separated from the ferrite 23. At the same time, the rice cooking valve 15 is closed and the rice cooking is finished.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cooker equipped with a gas stove that has a thermoswitch made of ferrite and a magnet, and that has the functions of both a general gas stove and rice cooking. be.

Conventional configurations and their problems In the past, there was a stove-top rice cooker, but that appliance did not have a temperature sensor on the stove side, but instead had a temperature sensor on the pot side. Also, in the case of automatic rice cookers with a thermoswitch that is a combination of ferrite and magnets, there is a thermoswitch as a temperature sensor on the stove side, but there is no temperature sensor on the pot side.

The latter had a temperature sensor on the stove side, so the adsorption between the ferrite and the magnet forced the gas valve to open, opening the gas circuit and causing combustion, making it impossible to cook above the Curie point of the ferrite. Also, if you forcefully open the gas circuit and burn it, the temperature may rise above the Curie point of the magnet, and the magnet will lose its magnetism and will no longer be attracted to the ferrite, so it will no longer function as a thermoswitch. , the gas circuit cannot be opened and the equipment will lose its capacity.

On the other hand, with a thermoswitch made of ferrite and a magnet, the operating temperature is determined by the Curie point of the ferrite, and temperature control is easy by simply controlling the temperature of the ferrite during manufacturing.
Since the gas valve is opened using the force of the magnet adhering to the ferrite, it has the advantage of a simple structure and fewer failures.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a cooking device that is equipped with both a general gas stove and an automatic rice cooking function.

Structure of the Invention In order to achieve the above object, the present invention utilizes the advantages of a thermoswitch made of ferrite and a magnet.On the other hand, when used as a general stove, regardless of the Curie point of the ferrite, the nozzle can be connected to the nozzle from the appliance cock like conventional gas stoves. The gas is then sent to the burner for combustion. Moreover, the thermo switch is lower than the highest part of the stove burner, which is lower than the stovetop.
That's how it is. Therefore, even if the magnet burns dry, it will not reach the temperature of the Curie point (for example, 350'C) and will not lose its magnetic force.

Also, in a normal state, even if you operate the rice cooking gas valve to open it, the ferrite is constructed so that there is a distance that the magnet will not reach. Unfortunately, regular kettles and pots have a safe structure that prevents the rice cooking gas circuit from opening. Therefore, a special rice cooker is provided for rice cooking, and only when this rice cooker is used, the thermoswitch is pressed down by the α dimension, and at this time, when the rice cooking button is pressed and F is lifted, the ferrite and magnet attract each other and open the gas circuit. .

Description of examples Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an external perspective view of an embodiment of the present invention.

FIG. 2 is a functional block diagram of the embodiment of the present invention when the stove is used, and FIG. 3 is a functional block diagram of the same when cooking rice. Figure 4 is a detailed view of the vicinity including the thermoswitch.

1 in Figure 1 is BJ! 4. 3° burner like E stove 2 with 4. Thermo switch5. It is equipped with an appliance cook knob 6, a rice cooking button 7, and a display board 8 indicating the stove, rice cooking and stop, and the operating direction of the rice cooking button 7. The right stove 9 is a general stove.

The appliance cock 1o in FIG. 2 shows the gas circuit of the stove, and gas is ejected from the stove opening 11 of the appliance cock 1o through the nozzle block 12, from the nozzle 13 to the burner 4, and from the pan 1.
4 is being heated. 15 is a rice cooking valve, and a lever 16 connected to the rice cooking button 7 and a valve rod 17 are spaced apart from each other. Reference numeral 18 denotes a lever rotating shaft, which is movably connected to the magnet 20 of the thermoswitch 6 at a lever A section 19. 21 is a magnet front spring, 22 is a magnetol-1-, 23 is a ferrite, and 24 is a case spring that always pushes the thermoswitch 5 upward. 2
5 is attached to the burner 4 lower than the top surface of 3 like a heat shield cylinder.

FIG. 3 shows the state during rice cooking, in which the rice cooking opening 26 of the appliance cock 10 is opened and gas enters the rice cooking valve 16. Therefore, the instrument cock 10 is connected to the display board 8 by the instrument cock knob 6.
I was intimidated by the rice cooking display, and next I turned on the rice cooking pot 27.3
When rice cooking button 7 is pressed down while rice is placed on rice cooker valve 1,
The valve rod 17 of No. 5 is pushed down by the lever 16, and the gas is ejected from the nozzle block 12 through the nozzle 13 to the burner 4. When lever 16 is pushed down, lever A
Magnet rod 20 and magnet 22 by part 19
is pushed up via the magnet front spring 21. At this time, the thermo switch 5 is pressed down by the dimension a by the convex part 28 at the center of the bottom of the rice cooking pot 27, so the magnet 22 reaches the ferrite 23, so the magnet 22 is attracted to the ferrite 23, and the rice cooking valve 16 is opened. state. Naturally, when the rice cooking is finished, the temperature of the ferrite 23 reaches the Curie point of the ferrite 23, and due to the repulsive force of the valve spring 28 of the rice cooking valve 16 and the weight of the lever 16, the magnet 22 is released from adsorption with the ferrite 23 and separated. At the same time, the rice cooking valve 16 is closed and the rice cooking ends.

In FIG. 4, when the stove is on, the thermo switch 6 is pushed up by the case spring 24 to the highest position, so even if the rice cooking button 7 is pushed down, the ferrite 2
In order to maintain the space λ where the magnet 22 cannot be attracted,
The lever 16 is configured so that the stopper 30 provided on the thermoswitch mounting base 29 comes into contact with the lever 16. The space λ is such a distance that the magnet 22 can be attracted to the ferrite 23 when the α dimension thermoswitch 6 is pressed down in the rice cooking pot 27. That is, the relationship is λ-a-(1 to 3″1).

In addition, the magnet rod spring 21 has a receiver 31, and the receiver allows the magnet 22 to move up and down by a retaining ring 32 that fixes the magnet rod 20 under the lever A portion 19.

Effects of the Invention As described above, the present invention takes advantage of the simple structure of the thermoswitch made of ferrite and magnets, and provides a heat shield tube to prevent the thermoswitch from overheating so that it can be used freely as a general stove. The sword is lowered at the bottom. Therefore, the magnet never loses its magnetic force. Also, when cooking rice, unless you use a special pot for rice cooking, the ferrite and magnet will not be close enough to attract each other, so even if you set one cooker to the rice cooking mode and press the rice cooking button, it is not safe to use with a regular cooking container. It is taken. The gas opening of the appliance cock is divided into the stove and rice cooking by the appliance cock knob, which together with the thermo switch ensures double safety when cooking rice and prevents mistakes. Therefore, the present invention provides a cooker that is compatible with the rice cooking function of the thermoswitch made of ferrite and magnets, which is the most commonly used rice cooker on the market today, without impairing the function of the stove. This eliminates the need for a dedicated gas valve or gas hose, which is advantageous from a safety standpoint. Also, there is no space left to put a gas rice cooker or electric rice cooker, and the small kitchen can be used more effectively.
