The present invention relates to a structure used for mounting a cooking temperature detecting device for ensuring safety by shutting off.

[0002]

2. Description of the Related Art In recent years, it has become widespread to attach a cooking temperature detecting device for detecting the temperature of the bottom of a cooking appliance such as a pan to a gas stove. The following structure is generally adopted. A mounting plate a for mounting a spark plug or a thermocouple is disposed horizontally, and the mounting plate a is fixed to the casing side of the gas stove. At the end of the mounting plate a, as shown in FIG. To form a bent piece b in the vertical plane, and the cooking temperature detecting device A is arranged in the vertical direction so as to pass through the center of the burner main body, and the lower part of the cooking temperature detecting device A is aligned with the bent piece b. And was fixed with the fixing bracket c.

[0003]

In the above conventional example, the lower part of the cooking temperature detecting device A is attached to a bent piece b bent at an angle of 90 ° with respect to the mounting plate a, thereby enabling the cooking temperature detecting device A to be mounted. Although it can be attached in the vertical direction, it is difficult to accurately bend the bent piece b at an angle of 90 ° with respect to the mounting plate a, and the bent piece b can be correctly oriented in the vertical direction. I ca n’t,
In addition, the bent piece b cannot be positioned on the burner main body side, and the verticality of the cooking temperature detecting device A is poor, so that the temperature can be easily hit against the bottom surface of a cooking appliance such as a pan, and an accurate temperature is detected. There is a problem that you can not. Also, there is a problem that the centering accuracy of the sensor unit f of the cooking temperature detecting device A with respect to the burner unit e is poor.

SUMMARY OF THE INVENTION The present invention has been made in view of the above description, and has a cooking temperature detecting device capable of accurately detecting a temperature of a bottom surface of a cooking appliance such as a pot by accurately attaching a cooking temperature detecting device. An object of the present invention is to provide a structure for mounting a detection device.

2, a cooking temperature detecting device A is attached to the end piece 2a of the burner fixing plate 2. By attaching the cooking temperature detecting device A in this manner, the end piece 2 of the burner fixing plate 2 is provided.
The temperature detecting device A for cooking can be installed upright so as to be orthogonal to a. On the lower surface side of the burner main body 1, a pair of bosses 55 are integrally erected downward.
The boss 55 has a female screw hole 55a drilled upward from the lower surface. The lower surface of the boss 55 is a horizontal plane. Then, the cooking temperature detecting device A is oriented vertically so as to be inserted into the center of the burner main body 1, the end piece 2a of the burner fixing plate 2 is aligned with the lower surface of the boss 55, and the mounting hole 53 is provided.
The fixing screw 56 is screwed into the female screw hole 55a of the boss 55 from above to fix the end piece 2a of the burner fixing plate 2 to the boss 55. By attaching the burner fixing plate 2 along the horizontal burner main body 1 in this manner, the end piece 2a of the burner fixing plate 2
Are mounted horizontally, and the cooking temperature detecting device A is mounted vertically on the horizontal end piece 2a, so that the cooking temperature detecting device A can be accurately mounted so as to face the vertical direction. Cooking temperature detection device A with the cooking temperature detection device A attached to face vertically
Is inserted through a through hole 59 at the center of the tray 4d, and protrudes upward from the through hole 59. The end piece 2c of the burner fixing plate 2 is fixed to the burner base 58 with fixing screws 57.

As described above, the end piece 2a of the burner fixing plate 2
Is a horizontal surface, and the mounting hole 53 for fixing to the burner main body 1 and the insertion hole 51 for mounting the cooking temperature detecting device A are located on the same horizontal surface, so that the cooking temperature detecting device A is accurately mounted. And the cooking temperature detecting device A can be accurately erected vertically with respect to the burner main body 1. That is, the burner fixing plate 2 is formed as in the comparative example as shown in FIG. 9, and the planes α and γ having the mounting holes 53 for mounting to the burner main body 1 and the through holes for mounting the cooking temperature detecting device A are provided. When the plane β having the holes 51 and the fixing holes 52 is not located on the same horizontal plane, the plane β is unlikely to be a parallel plane with respect to the planes α and γ due to processing accuracy, and the plane α and the plane γ itself are also parallel planes. It is hard to become. This is because L ₁ and L ₂ in FIG.
This is also because each bending angle (90 °) varies.
Therefore, in the case of the burner fixing plate 2 as shown in FIG. 9, it is likely that the cooking temperature detecting device A cannot be accurately attached. However, when the portion having the mounting hole 53 and the portion having the insertion hole 51 are on the same horizontal plane as in the present invention, the cooking temperature detecting device A can be accurately mounted without the above-described variation. .

When a cooking appliance such as a pot is placed on the kitchenware 4, the heat collector 30 of the cooking temperature detecting device A elastically contacts the bottom surface of the cooking appliance. When the cooker is heated by the burner and cooking is performed, the temperature of the bottom surface of the cooker is detected by the thermistor element 32. However, when cooking such as oil cooking, the thermistor element 32 is used. When it is detected that the temperature at the bottom of the cooking appliance has become equal to or higher than a predetermined value, the supply of gas is shut off. In the case of the present invention,
As described above, the cooking temperature detecting device A is attached to the burner fixing plate 2 attached to the lower surface of the burner main body 1 and the cooking temperature detecting device A is mounted so as to be oriented vertically. The heat collector 30 can stably and accurately hit the bottom surface of the cooking appliance without the heat collector 30 at the upper end colliding with the bottom surface of the cooking appliance, and the temperature can be accurately detected by the thermistor element 32. At this time, since the virtue 4 is attached to the burner main body 1 via the top plate 3, the virtue 4 and the cooking temperature detecting device A are relatively positioned via the burner main body 1, and are positioned on the gotoku 4. The heat collector 30 of the cooking temperature detecting device stably comes into contact with the bottom surface of the placed cooking utensil.
