Description

[Detailed Description of the Invention] The present invention relates to an electric cooking device that includes a hot plate such as a pot or a hot plate, and a first heater and a second heater.

As shown in the perspective view of FIG. 1, a conventional electric cooking appliance has a heating plate 2, which has a heater 1 mounted on an aluminum or other metal plate by casting or crimping, such as a sheathed heater, and the heating plate 2.
A plug cover 4 is provided on one side, a terminal 3 connected to a heater 1 is led out into the plug cover 4, and a plug-in thermostat 5 is detachably attached to the plug cover 4.

The plug-in thermostat 5 senses the temperature of the hot plate 2 and is electrically connected to the terminal 3.

The hot plate 2 is equipped with one heater 1, but with only one heater 1, the entire surface of the hot plate 2 is always heated, and the baked food cannot be kept warm during cooking. However, even when cooking a small amount, the entire heating plate 2 must be heated, which consumes a large amount of power.

Furthermore, in an electric cooker equipped with two heaters 1 of different capacities as a well-known hot plate 2, the two heaters 1 are controlled simultaneously, and the heater circuit is changed to series or parallel. Therefore, the plug-in thermostat has a complicated heater switching mechanism.

The present invention solves the above-mentioned problems, and also provides a guard rod that also serves as a handle on the plug cover 4, making it portable and serving as a guard rod to prevent burns from the hot plate 2.

The present invention will be explained with reference to the embodiment shown in Fig. 2.
The figure is a perspective view of an electric cooker, in which a first heater 6 and a second heater 7 are placed on one side of a hot plate 8 facing each other. A plug bar 10 having a connected terminal 9 is provided, and a plug cover 10 having a terminal 9 connected to the second heater 7 is provided on the other side of the hot plate 8.
A plug-in thermostat 11 for temperature sensing and electrical connection of the hot plate 8 is made detachable, and a guard rod 12 which also serves as a handle is provided between the plaque cover 10 and separated from the surroundings of the hot plate so as to be rotatable. To explain in more detail from the plan view of FIG. 3, for example, the first heater 6 has a power of 1 kW,
The second heater 7 has a power of 600 W, and the plug-in thermostat 11 can be used as either the first heater 6 or the second heater 7.

In other words, if you want to use about half of the hot plate 8, use the second heater 7, and if you want to heat the entire hot plate 8, put a plug in the plug cover 10 that has the terminal 9 connected to the first heater 6. The heater 6 is heated by inserting the in-thermostat 11.

4 is a side view, and FIG. 5 is a side sectional view. The plug cover 10 is made of resin and is fixed to the bottom of one side of the hot plate 8 with screws 13 in the embodiment.

The heater 6 is provided with a terminal 9 at its end, and the plug cover 1
0, and the plug-in thermostat 11 is inserted.

14 is a through hole into which a heat-sensitive rod of the plug-in thermostat 11 is inserted, and this through hole 14 is provided integrally with the heat plate 8.

Furthermore, this plug cover 10 is provided with a hole into which the end of a guard rod 12 which also serves as a handle is inserted and fitted, so that when the guard rod 12 rotates and is located near the height of the end surface of the hot plate 8, it becomes a stopper. A base portion 15 is provided on the plug cover 10.

Moreover, by rotating the guard rod 12 upward, it becomes a handle of the electric cooking device and can be carried.

Reference numeral 16 indicates legs that are appropriately selected and provided on the bottom surface of the hot plate 8.

Plug-in thermostala)・5 shown in the conventional example above,
The present invention can be used as is, and since the guard rod 12 which also serves as a handle can be attached to a part of the plug cover 10, the number of parts can be reduced and an extremely effective electric cooking appliance can be provided.
