Description

[Detailed description of the invention] The present invention is an electric cooker in which a cooking plate is freely placed on a heat source such as a sheathed heater. This invention relates to a connection device with a temperature regulator for setting and maintaining a predetermined value, and will be explained below with reference to an embodiment shown in the drawings.

In FIG. 1, reference numeral 1 denotes a cooking device main body, and a heat source 3 such as a sheathed heater is attached to a reflecting plate 2 provided in a recessed portion of the top surface of the cooking device by appropriate means.

Reference numeral 4 denotes a cooking plate placed on the heat source 3 during cooking, and in the embodiment, a plate for grilling meat is shown having a raised portion 4a in the center and a recessed portion 4b on the outer periphery.

Reference numeral 5 denotes a heat-sensitive tube provided on one side of the cooking device body 1 so as not to be directly exposed to the radiant heat of the heat source 3, and biased so as to penetrate through a through hole 1a formed in the body 1 and protrude upward. The heat-sensitive tube has a large-diameter heat-receiving portion 5a at its upper end that contacts the outer bottom surface of the recessed portion 4b of the cooking plate 4, and a stopper plate 5b on its lower periphery.
A spring 6 is provided inside.

The lower end of the spring 6 is attached to the cooking device main body 1, and the support frame ₇ has a substantially rectangular cross section and has a through hole 7a1 in the upper wall 7a through which the heat sensitive tube 5 passes. The heat-sensitive tube 5 is placed on the lower wall 7b, and therefore is always urged upward as described above.

Reference numeral 8 denotes a normal bimetal type thermostat attached to one side wall 7c of the support frame 7, which is composed of a pair of contact plates 8a, 8b, a bimetal 8c, a rotating shaft 8d for adjusting the set temperature, etc., and a detailed explanation thereof is provided below. and illustrations are omitted.

Reference numeral 9 is attached to the thermostat 8, and the heat-sensitive tube 5 is fitted as a heat transfer body so as to be slidable up and down (see Fig. 2).When the cooking plate 4 is not placed, the heat-sensitive tube 5 is The spring 6 causes the stopper plate 5b to protrude outward from the cooking device main body 1 while being in contact with the lower end of the heat transfer body 9.

Reference numeral 10 designates an adjustment knob, which is rotatably attached to the side wall of the cooking device main body 1 and is detachably connected to the rotation shaft 8d of the thermostat 8.

Therefore, when the cooking plate 4 is placed on the heat source 3 during cooking, the heat receiving part 5a of the thermosensitive tube 5 is pushed down against the spring 6 by the outer bottom surface of the recessed part 4b of the cooking plate 4, The outer bottom surface and the heat-receiving part 5a come into contact with each other elastically, and the heat-sensitive tube 5 is removed from the cooking plate 4.
The thermostat 8
The temperature of the cooking plate 4 is maintained at a predetermined value by sensing the temperature of the bimetal 8c.

As described above, in the present invention, the heat-sensitive cylinder, which moves up and down when the cooking plate is attached and detached, and which comes into elastic contact with the outer bottom surface of the cooking plate, is placed on one side of the cooker body so that it does not directly receive radiant heat from the heating source. Because of this, the heat-sensitive cylinder can accurately measure the temperature of the cooking plate, and the vertically moving heat-sensitive cylinder is slidably fitted into the heat transfer body attached to the fixed thermostat, so the adjustment knob can be adjusted easily. This electric cooking appliance is extremely easy to use, as it can be connected to the rotary shaft for adjusting the set temperature of the thermostat by a simple connection means such as fitting.
