Description

TECHNICAL FIELD The present invention relates to a hot plate in which a plate is separated from a heater and only the plate can be attached and detached.

2. Description of the Related Art Heretofore, a cooker of this type has been disclosed, for example, in Japanese Utility Model Laid-Open No. 57-121.
The structure was as shown in Japanese Patent No. 228.

That is, as shown in FIGS. 6 and 7, a plate 2 as a cooker body is supported by a heater body 1, and a heat shield plate 3 is attached to the inside of the heater body 1. A heating element 4 is fixed on the upper surface of the heat shielding plate 3, and the heat shielding plate 3 is formed in a convex shape at the center of the heating element 4 to provide a convex portion 3a. A hole 5 is provided at the center of the convex portion 3a.
The thermosensitive portion 8 of the thermostat 7 that abuts the lower heating surface 6 of the plate 2 through this hole 5 projects upward.

The thermostat 7 is provided on a concave mounting plate 9 having a spring property, which is fixed below the convex portion 3 a of the heat shield plate 3. In the thermostat 7, the fixed contact 11 provided on the fixed plate 10 and the movable contact 13 provided on the movable plate 12 are opposed to each other, and the pusher 15 provided on the bimetal plate 14 is opposed to the tip of the movable plate 12. , Each of the above plates 10, 12,
The insulating members 16 hold the members 14 in parallel and are integrated with each other, and these members 14 are integrally provided on the heat-sensitive portion 8.

However, in such a structure, the slidability of the heat-sensitive part 8 is determined only by the spring property of the mounting plate 9, and the heat-sensitive part 8 can be slid up and down sufficiently. In addition, since there is no stability, there is a problem that the heating surface 6 of the plate 2 pushes the heat-sensitive portion 8 too much due to dimensional variation, or conversely, it becomes bulged and the sensitivity is not well received. Further, when such a bimetal type thermostat 7 is used, a large space is required for the mounting portion of the bimetal 14 so that the bimetal 14 and the pressing element 15 do not come into contact with other parts, and the product becomes unnecessarily large. There was

Therefore, the present invention solves such a problem, and the sliding of the heat receiving plate that receives the plate temperature is sufficient, the plate surface and the heat receiving plate are in close contact, and the sliding when the plate is placed is stable. Therefore, even if a bimetal type thermostat is used, it is possible to provide a cooker whose size is reduced.

Means for Solving the Problems In order to solve the above problems, the present invention comprises a main body having a heater, a plate detachable from the main body, and a heat receiving plate which is in contact with the plate and receives the temperature of the plate. It consists of a vertically slidable cap and an automatic temperature controller that controls the plate temperature via the heat receiving plate, and a protrusion protruding to approximately the same height as the upper surface of the heat receiving plate is provided near the outer periphery of the upper surface of the cap. It has a different structure.

With this configuration, the cap having the heat receiving plate that receives the plate temperature can slide up and down, and since the projection is provided near the outer periphery of the upper surface of the cap, even if the plate is obliquely placed. Since the plate surface, the heat receiving plate and the projection are in immediate contact with each other, the plate surface can slide up and down with a slight inclination of the cap, and the sliding can be stabilized, and the plate surface and the heat receiving plate can be in close contact with each other. In addition, the above protrusion serves as a relief for the bimetal insulator attached to the tip of the bimetal of the bimetal type thermostat, and the space for the mounting part of the bimetal type thermostat can be reduced. You can get excellent results.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1 to FIG. 4, 17 is a cooker main body, 18
Is a plate that can be attached to and detached from the cooker main body 17, and a cap 19 is attached to the main body 17 via a spring 25 so as to be slidable up and down. The cap 19 has a plate 18
A heat receiving plate 20 that contacts the plate 18 and receives the temperature of the plate 18 is caulked and attached. An automatic temperature controller 21 is attached to the heat receiving plate 20 with a nut 22, and the automatic temperature controller 21 controls the temperature of the plate 18. A bimetal 23 is attached to the automatic temperature controller 21, and the bimetal 23 has an insulator 24 at its end. A protrusion 29 is provided in the vicinity of the outer periphery of the cap 19 so as to protrude to substantially the same height as the upper surface of the heat receiving plate 20. The protrusion 29 is located above the bimetal insulator 24. The heater 26 is fixed to a heat shield plate 28 inside the cooker main body 17 via a heater support fitting 27.

With such a configuration, the cap 19 can easily slide up and down, sufficiently absorb the variation in the component dimensions of the plate 18, etc., and obtain a better close contact state between the plate 18 and the heat receiving plate 20. You can Also cap 1
Since the projections 29 are provided on the upper surface of the plate 9 at substantially the same height as the heat receiving plate 20, even if the plates are placed diagonally as shown in FIGS. Since the projections 29 and the projections 29 come into immediate contact with each other, a slight inclination of the cap 19 is required, and the correction is immediately corrected. Therefore, the cap 19 comes into contact with the surrounding wall 30 during the vertical sliding operation to hinder the sliding. Better sliding and plate 1 without
It is possible to obtain a close contact state between 8 and the heat receiving plate 20. Further, the protrusion 29 is the bimetal insulator 2 provided on the automatic temperature controller 21.
The cap 19 of the bimetal insulator 24 is provided on
As a result, the space between the upper surface of the cap 19 and the bimetal 23 can be reduced, and the product as a whole can be miniaturized, which has a great effect.

EFFECTS OF THE INVENTION As is apparent from the above embodiments, the cooking device of the present invention includes a main body having a heater, a plate detachable from the main body, and a heat receiving plate that is in contact with the plate and receives the plate temperature. It consists of a vertically slidable cap and an automatic temperature controller that controls the plate temperature via the heat receiving plate, and a protrusion protruding to approximately the same height as the upper surface of the heat receiving plate is provided near the outer periphery of the upper surface of the cap. As a result, the cap provided with the heat receiving plate that receives the plate temperature can slide up and down, and since the projection is provided near the outer periphery of the upper surface of the cap, even if the plate is placed diagonally, Since the plate surface, the heat receiving plate and the protrusion come into immediate contact, they can slide up and down with a slight inclination of the cap, and the sliding is stable and the plate surface and heat receiving plate are in close contact. Can be well. In addition, the above-mentioned projection becomes the escape of the bimetal insulator attached to the tip of the bimetal of the bimetal type thermostat, the space of the mounting part of the bimetal type thermostat can be made small, the product as a whole can be made small, and it is not necessary to use unnecessary members. A product that is excellent in terms of cost can be obtained and has a great effect.
