Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cooking appliance, and more particularly to a cooking appliance that is equipped with a temperature sensor and automatically extinguishes the fire when a set temperature is reached.

(Prior Art) Conventionally, as shown in Fig. 8, a gas burner A,
A gas safety valve C interposed in the gas passage B of the gas burner A, a thermoelectric generating element D such as a thermocouple that holds the gas safety valve C heated by the flame of the gas burner A open, and a thermoelectric generating element D such as a thermocouple that holds the gas safety valve C heated by the gas burner A open. A cooking device in which a gas burner A is extinguished by a switch E which is opened when the temperature reaches a set temperature when it comes in contact with a pot or other cooking utensil is known, for example, from Japanese Utility Model Publication No. 37-26498. According to this, when the set temperature is reached, the switch E opens and the gas burner is extinguished, so that there is no need for ignition of frying oil during cooking of fried chicken, for example.

However, the gas burner has the inconvenience of extinguishing even when it is desired to cook at a temperature higher than the set temperature of the temperature sensor, for example, to cook fried noodles at a high temperature. Therefore, in preparation for such double-sided cooking, the temperature sensor can be freely moved between an active position where it touches the pot and an inactive position where it does not touch the pot. It is better to be in the operating position.

(Problem to be solved by the invention) If the temperature sensor can be freely moved between the operating position and the non-operating position as described above, it is possible to cook at a temperature higher than the set temperature. If you forget to return the sensor to the operating position, the gas burner will not extinguish even when the set temperature is reached, causing the inconvenience of ignition due to ignition of the cooking oil.

(Means for Solving the Problems) Therefore, in order to solve this problem, the present invention includes a heat source, a sensor that detects the temperature in contact with a cooking pot heated by the heat source, and a sensor that detects the set temperature. A displacement device that allows the temperature-sensitive sensor to be freely displaced between an operating position in contact with the cooking pot and an inoperative position in which it does not contact the cooking pot, in a cooking device comprising a control device that controls extinguishing of the heat source when detected. and a drive device that brings the temperature sensor, which has been placed into an inactive position by the displacement device, into an active position by igniting or extinguishing the heat source.

(effect) The above technical means of the present invention operates as follows.

First, let's assume that the temperature sensor is set to, for example, 210 degrees Celsius. Cook tempura in the operating position where the temperature sensor touches the pot. The temperature of the pot reaches 210℃,
When the temperature sensor detects this, the control device extinguishes the heat source. Next, when performing high-temperature cooking such as yakiniku, the temperature sensor is moved to a non-operating position by the displacement position. As a result, even if the frying pan or the like reaches the set temperature, the temperature sensor does not detect it, so the heat source continues to ignite and cooking can be performed. When the heat source is extinguished at the end of the high-temperature heating, or when the heat source is ignited at the start of the next cooking, the temperature sensor is set to the operating position by the drive device and is ready for the next tempura dish. If high-temperature cooking is to be performed next time, the temperature sensor is set to the inactive position.

(Effects of the Invention) Since the present invention has the above configuration, it has the following effects. Equipped with a temperature sensor, when the set temperature is reached, the Etsugen automatically turns off and does not heat up any further, making it safe. Also, if you want to heat the food to a temperature higher than the set temperature, you can heat the food at a high temperature by setting the temperature sensor to the inactive position. Even if the temperature sensor is in the inactive position, it will be activated by igniting or extinguishing the heat source.When using the cooker, the temperature sensor will always be in the activated position, and the temperature sensor will be activated. This eliminates the inconvenience of forgetting to set the position.

(Embodiment) In the embodiment shown in FIGS. 1 to 3, 1 is a gas burner as a heat source, which heats a cooking pot 2 placed thereon. 3 is a temperature sensor (for example, a bimetal switch) that senses the temperature in contact with the cooking pot 2;
When the set temperature (for example, 210° C. for cooking tempura) is detected, the control device 4 extinguishes the heat source 1. In this example, the control device 4 is an electromagnetic safety valve that is opened by suction by a thermocouple 5 that generates an electromotive force by a flame, and the bimetal switch that is the temperature sensor 3 is connected to the thermocouple 5.
and the circuit 6 of the electromagnetic safety valve, which is the control device 4.

The temperature sensor 3 is movable up and down by a displacement device 7, and can be freely displaced between an operating position in contact with the cooking pot 2 and an inoperative position in which it does not contact the cooking pot 2.

The displacement device 7 includes a displacement guide 71 and a displacement lever 7.
2. It consists of a support 73 and a holding means 74 (for example, a magnet). When the tip of the displacement lever 72 is lowered, the temperature sensor 3 is guided by the displacement guide 71 and rises to the operating position where it contacts the cooking pot 2. Become.

On the other hand, when the tip of the displacement lever 72 is raised, the temperature sensor 3 is guided by the displacement guide 71 and descends.
It becomes an inoperative position away from the cooking pot 2.

FIG. 1 shows a state in which the temperature sensor 3 is in the operating position by the displacement device 7 for cooking tempura. Specifically, the tip of the displacement lever 72 is pushed down and held by the holding means 74. The temperature sensor 3 is in an operating position in contact with the pot 2.

When the operating knob 9 is turned to the igniter, the heat source 1 is ignited by the igniter (not shown) and the pot 2 is heated. When the temperature sensor 3 detects the set temperature, the circuit 6 is opened, so that the electromagnetic safety valve, which is the control device 4, is no longer attracted and held, and the electromagnetic safety valve closes to stop the flow of gas. This extinguishes the heat source 1, so there is no inconvenience such as overheating the pot and igniting the frying pan oil.

8 is a drive device which will be explained in detail later.

FIG. 2 shows a state in which the temperature sensor 3 is in the inoperative position due to the high temperature cooking of fried soba noodles, etc., and specifically, the displacement lever 7
The tip end side of the sensor 2 is lifted to place the temperature sensor 3 in a non-operating position where it does not come into contact with the pot 2.

At this time, since the temperature sensor 3 is away from the pot 2, the temperature sensor 3 does not operate even if the set temperature is reached, and therefore the heat source 1 continues to be lit.

As described above, since the temperature sensor 3 can be displaced between the operating position and the non-operating position by the displacement device 7, cooking controlled by the set temperature of the temperature sensor 3 and cooking at a higher temperature can be performed. . However, if you forget to set the temperature sensor 3 to the inactive position for high-temperature cooking and cook tempura, the temperature sensor 3 will not work and the tempura oil may be heated too much, causing the inconvenience.

Therefore, a drive device 8 is provided which brings the temperature sensor 3, which has been placed in the inoperative position by the displacement device 7, into the activated position by extinguishing the temperature using the operating knob 9. To explain this in detail, the drive device 8 is operated by the operation knob 9.
When the operating knob 9 is in the ``ignition'' rotation position, the cam body is positioned upward (see Figures 1 and 2), and when the operating knob 9 is in the ``extinguishing'' position, the cam body is positioned upward (see Figures 1 and 2).
In the rotational position of , the cam body is located downward (Fig. 3).

Therefore, when the operating knob 9 is in the "ignition" position, the first
As shown in FIG. 2, the distal end side of the displacement lever 72 can be raised, and the temperature sensor 3 can be displaced to a non-operating position.

Also, in the "extinguishing" position of the operation knob 9 in Fig. 3,
The drive device 8 presses the distal end side of the displacement lever 72, and the temperature sensor 3 is in the operating position.

Also, as shown in Fig. 2, a displacement device 7 is used for high-temperature cooking.
Considering the usage condition in which the temperature sensor 3 is set to the inactive position after the ignition operation, when the operation knob 9 is turned off after cooking, the tip side of the displacement lever 72 is lowered by the cam body serving as the drive device 8. The temperature sensor 3 is placed in the operating position (FIG. 3).

Accordingly, the temperature sensor 3 is in an operating position in contact with the pot 2 in preparation for the next cooking. If you are going to perform high-temperature cooking next time, turn off the "extinguish" button on control knob 9.
In the rotation position, the cam body becomes an obstacle and the displacement lever 7
Since the distal end side of the displacement lever 72 cannot be lifted, the temperature sensor 3 can be placed in the inoperative position by lifting the distal end side of the displacement lever 72 after the ignition operation.

4 and 5 show an example in which, if the temperature sensor 3 is in the inactive position, the temperature sensor 3 is brought into the active position by igniting the heat source 1 using the operating knob 9. In this embodiment, the drive device 10 includes a pinion 11 coaxial with the operating knob 9,
It consists of 12 racks. In FIG. 4, when the operating knob 9 is in the ignition position, the rack 12 is lowered and the distal end of the displacement lever 72 is pushed down. This brings the temperature sensor 3 into the operating position.

To explain this in more detail, considering the "extinguishing" state of the operation knob 9 (when the ▲ of the knob 9 is in the OFF position), if you turn the ignition in the direction of the solid line arrow from this state, the pinion 11 will also move in the direction of the solid line arrow. Rotate and lower the rack 12 as shown by the solid arrow.

As a result, the distal end side of the displacement lever 72 is pushed down and the temperature sensor 3 is moved to the operating position shown in FIG. 4 in a raised position.

If you are cooking tempura, you will cook it in this state.

However, depending on the cooking, the cooking temperature may be higher than the temperature set by the temperature sensor 3. At this time, the tip end 721 of the displacement lever 72 is pulled against the spring 75. The notch 722 of the tip 721 is easily
When located at the lower end of the lever 72, the distal end side of the displacement lever 72 is lifted by the spring 76, as shown in FIG. At this time, the temperature sensor 3 is in the inactive position. This allows high-temperature cooking at a temperature higher than the set temperature of the temperature sensor 3.

At the end of this high-temperature cooking with the temperature sensor 3 in the inoperative position, the rack 12 is raised via the pinion 11 when the operation knob 9 is turned in the direction of the dotted line arrow to extinguish the fire. Then, the lower end of the rack 12 comes off the notch 722, so the tip 721 is pulled by the spring 75 and the notch 722 comes off the lower end of the rack.

Next, when you perform the ignition operation, it will be easy 12 as mentioned above.
The lower end of the displacement lever 72 pushes down the tip side of the displacement lever 72 to bring the temperature sensor 3 into the operating position.

In addition, when the temperature sensor 3 is in the operating position in the ignition state shown in Fig. 4 and the fire is extinguished after cooking the tempura, the rack 12 is raised and the displacement device positions the temperature sensor 3 in the inoperative position. .

FIGS. 6 and 7 show another example in which, if the temperature sensor 3 is in the inoperative position, it is brought into the operating position by igniting the heat source 1 using the operating knob 9.

The drive device 13 consists of a pinion 11 and a rack 12. The rack 12 is pivotally supported on a displacement lever 72 by a shaft 14, and is pressed against the pinion 11 by a spring 15. 16 is a release lever.

FIG. 6 shows a state in which the operating knob 9 has been rotated to the ignition position. The rack 12 has been lowered and the distal end side of the displacement lever 72 has been pushed down so that the temperature sensor 3 is in the operating position.

If you are cooking tempura, you will cook it in this state.

However, when you want to set the temperature sensor 3 to the inactive position for high-temperature cooking, release lever 1
Turn 6 in the direction of the arrow. As a result, the rack 12 is disengaged from the pinion, and the distal end of the displacement lever 72 becomes free, and the temperature sensor 3 is lowered to the inoperative position by the spring 77 (FIG. 7).

When high-temperature cooking is finished, that is, when the temperature sensor 3 is in the inactive position and the operation knob 9 is turned in the direction of the dotted arrow to perform the fire extinguishing operation, the pinion 11 rotates away from the rack 12.

Therefore, the operating knob 9 is rotated to the "extinguish" position, but the rack 12 does not rise and the temperature sensor 3 remains in the inoperative position.

When the ignition is operated with the control knob 9 during the next cooking, the pinion 11 rotates, and the rack 12 is thereby lowered, so the tip side of the displacement gear 72 is pushed down and the temperature sensor 3 is moved against the spring 76 to the operating position. (See Figure 6).

At this time, if the temperature is controlled by the temperature sensor 3, cooking will continue as is, but if high temperature cooking is to be performed, as explained earlier, press the release lever 1.
If you turn 6 in the direction of the arrow, the rack 12 will be the pinion 11.
The distal end of the displacement lever 72 is raised by the spring 76, so that the temperature sensor 3 is lowered to the inoperative position (see FIG. 7).
