DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a cooker provided with a control master such as a hot plate.

[0002]

2. Description of the Related Art Conventionally, for example, a cooking device such as a hot plate is generally provided with a control master CM (see FIG. 18) for detecting a temperature of a plate portion and controlling a power supply state to a heater portion. .

As shown in FIG. 18, for example, the control master CM has connection jacks HG for connecting to the heater 4 at both ends of a main body thereof, and has a thermoplug TP of a predetermined length of a bimetal structure at a central portion thereof. The temperature of the plate portion 5 is detected by inserting the tip of the thermo plug TP into a thermo plug fitting groove 30 having a concave cross section provided on the lower surface of the plate portion 5.

[0004]

By the way, recently, in a cooking device such as the above-mentioned hot plate, versatility which enables use of a cooking plate having a particularly shallow bottom such as a grilled meat plate has been demanded. However, in a conventional cooking device such as a hot plate, as shown in the figure, the side wall 1A of the saucer-shaped main body case 1 is designed and manufactured on the basis of a normal hot plate 5 having a somewhat deep bottom. The shape is U-shaped in cross section, and the height is naturally high.

Therefore, a cooking container having a very shallow bottom such as a grilled meat plate cannot be used as it is.

Therefore, in response to the requirement of the versatility, for example, the upper end portion of the side wall portion 1A having the U-shaped cross section is formed thin in a flat plate shape and lowered to the upper surface position of the receiving cover 7 of the control master CM. It is considered that the entire main body case 1 is formed thin.

[0007] On the other hand, cookers such as grilled meat plates may be required to be similarly thinned from the standpoint of, for example, design.

However, with such a thin configuration, the upper surface of the receiving cover 7 is relatively susceptible to the heat radiated from the heater 4 and the cooking plate, so that it tends to be thermally deformed. This causes a problem that the control master CM cannot be fitted.

On the other hand, the control master C
The M thermo plug TP part is to the cooking plate part,
Since it is necessary to take a sufficient insertion length (contact length), the control master body is also fitted to the receiving cover 7 as close to the cooking plate as possible, but the body case is made thin. In such a case, the edge of the cooking plate portion whose overall height is low and its peripheral edge position is naturally too low is too close to the main body portion of the control master CM, and the main body portion made of phenol material or the like of the control master CM is a heater. It is not preferable because it is easily affected by heat. Therefore, the control master CM cannot be moved too close to the cooking plate.

However, in this case, it is difficult to obtain a sufficient insertion length of the thermoplug TP, and a new problem that the temperature detection performance is deteriorated occurs.

According to the present invention, thermal deformation and the like are prevented by covering the upper end of the flattened main body case side wall with a part of a receiving cover to reinforce heat insulation, and a thermo plug insertion groove of a cooking plate portion. By making the outer end project outward, the control master body is kept away from the cooking plate, and at the same time, a sufficient length of the thermoplug is inserted so that the above-mentioned conventional problems can be solved. It is intended to provide a vessel.

[0012]

Means for Solving the Problems In order to achieve the above object, the present invention is provided with the following means for solving the problems.

That is, the cooking device of the present invention comprises a main body case, a heater provided on the bottom of the main body case, a cooking plate mounted on the upper portion of the heater, and a thermo plug fitting groove of the cooking plate. A cooker comprising: a control master having a thermoplug that is inserted into the cooking plate to detect the temperature of the cooking plate; and a control master receiving cover provided on a side wall of the main body case. The upper edge located below the outer periphery of the cooking plate on the side wall of the case is formed in a flat plate shape, and the upper edge of the flat plate is fitted with the opening edge of the cooking plate side of the receiving cover. .

In the cooking device according to the present invention, a groove is formed at an opening edge of the cooking plate side of the receiving cover so as to be fitted to a flat upper edge of a side wall of the main body case of the receiving cover. It is configured.

Further, the cooking device of the present invention is configured such that the thermo-plug insertion groove portion of the cooking plate protrudes toward the receiving cover side for a predetermined length.

Therefore, the upper edge portion of the side wall portion of the receiving cover side below the outer peripheral edge portion of the cooking plate is thinly formed in a flat plate shape, and its height is set to the upper surface position of the receiving cover for fitting the control master. Even if it is configured to be lowered, the flat plate-shaped upper edge portion is sufficiently reinforced at the same time as the cooking plate side opening edge portion of the receiving cover is fitted and heat shielded, so that thermal deformation is less likely to occur and Durability also increases.

In this case, in particular, a groove is formed in the opening edge of the cooking plate side of the receiving cover, and the groove is fitted to a flat upper edge of the side wall of the main body case on the receiving cover side. When configured in combination, the above-mentioned heat shielding and reinforcing action becomes more sufficient.

Further, in each of these configurations, when the thermo plug of the control master is formed by projecting a predetermined length of the thermo plug fitting groove of the cooking plate into which the thermo plug of the control master is fitted, the corresponding amount of the thermo plug is formed. The control master main body can be fitted radially outwardly from the outer peripheral edge of the cooking plate and fitted to the receiving cover, so that the influence of heat can be reduced as much as possible. Moreover, it is possible to realize a sufficient length of the thermo plug inserted into the cooking plate.
Temperature control performance is also guaranteed.

[0021]

According to the structure of the cooker of the present invention, a cooker such as a hot plate can be used also as a grill plate, and the grill plate itself can be made thinner. . In addition, as described above, there is no need to cause problems such as thermal effects on the control master and thermal deformation of the side wall of the main body case.
It does not hinder the temperature sensing performance of the control master.
