CONSTITUTION:The cooker is constituted of a thermoassembly 22 in which a thermostat 7 is housed in a case 12, and also, a temperature adjusting control 9 is provided in the outside of the case 12, and moreover, a power source input part 13, a power source output part 13 and a temperature sensing part 15 are provided, a heating plate assembly 1 having a heating element 4 and a heater terminal 8 of its heating element 4, and a guard plate 16 for protecting at least the side face of the heating plate assembly 1, and also, covering the case 12 part of the thermoassembly 22.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker which is mainly used on a table and has a thermo assembly for turning on / off an electric heater incorporated therein.

[0002]

2. Description of the Related Art A heating cooker having a built-in electric heater generally has a thermo assembly connected or incorporated therein.
By making the temperature control knob provided on the thermo assembly variable, desired heating and cooking can be performed. On the other hand, the structure of a thermo assembly of a heating cooker of this type conventionally has a system shown in FIGS. 5 and 6, but FIG. 5 shows a device relating to the heating cooker of Japanese Utility Model Publication No. 3-16584. In the figure, reference numeral 22 is a thermo assembly, 8 is a heater terminal, and a receiver of a temperature controller (not shown) is connected to the heater terminal 8 and the power plug of the thermo assembly 22 is turned on. The sheathed heater 2 provided in the hot plate assembly 1 generates heat, and the hot plate assembly 1 is held at the temperature set by the temperature control dial 6.

FIG. 6 is an invention relating to an electric cooker disclosed in Japanese Patent Laid-Open No. 3-103209, in which 7 is a thermostat, 4 is a heating element, and the heating element 4 is energized when a power plug (not shown) is turned on. Then, the hot plate assembly 1 is heated. However, in each of the conventional examples described above, in which the thermo assembly 22 shown in FIG. 5 is inserted into and removed from the heater terminal 8, the heater terminal 8 by insertion and removal, and the thermo assembly 22 (not shown) is built in. There was a risk of electric shock and fire due to electrical deformation and mechanical failure of the heater terminal 8 and the metal receiver due to shape deformation and incomplete connection due to wear of the metal receiver, that is, half-contact.

Further, as shown in FIG. 6, in the case where the thermo 7 is assembled in the heating cooker 11 together with other parts of the thermo assembly 22, for example, the parts relating to the temperature control knob 9, in the assembling work, Before assembling the thermo 7 into the heating cooker 11, in a bare state, after making the thermo 7,
It takes extra care to move between the steps until it is assembled into the heating cooker 11 as the thermo assembly 22, or the parts relating to the temperature control knob 9 which is a part other than the thermo 7 are installed in the heating cooker 11. In order to function as the thermo assembly 22, when assembling the thermo 7 and the other parts, it is necessary to carry and move a relatively large heating cooker, and the heat of the hot plate assembly 1 is applied to the thermo assembly 22. Easy to reach the whole,
Since this time also increases, an extra heat-resistant member, for example, an insulating member for assembling the thermo 7 has to be used, and there is a problem that the cost increases.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the prior art, and can prevent the occurrence of electrical troubles due to wear of the thermo-assembly receiver.
Moreover, it is an object of the present invention to provide a relatively low-cost heating cooker which does not cause an electric shock fire and which does not increase the cost due to the use of a heat-resistant member for the thermo-inner member.

[0006]

In order to achieve the above object, the present invention has a thermostat housed in a case, a temperature control knob provided outside the case, a power input section, a power output section and a temperature sensing section. And a heating plate assembly having a heating element and a heater terminal for the heating element, and protecting at least the side surface of the heating plate assembly, and the case portion of the heating assembly with a card plate. It consists of a covered cooker.

[0007]

In the electric heating cooker having the above-mentioned structure, after the thermo assembly is assembled to the heater terminals of the heating element of the hot plate assembly,
It is assembled so that at least a part of the thermo assembly is covered with a guard plate, and a part of the thermo assembly, specifically other than the temperature control knob, is hidden by the guard plate to fix the thermo assembly. Is. That is, at the time of use, the heating element of the heating plate is heated at the temperature set by the temperature control knob by inputting the commercial power supply to the power cord extended to the input portion of the power supply.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side sectional view of a main part of a heating cooker 11 according to the first embodiment of the present invention, and FIG. FIG. First, in FIG. 1, the thermo 7 is housed in the case 12, the temperature control knob 9 is provided outside the case 12, and the thermo assembly 22 having the power input section 13, the power output section 14 and the temperature sensing section 15 is provided. The power supply output unit 14 of the thermo assembly 22 is connected to the hot plate assembly 1 that is provided and has the heat generating plate 4 and the heater terminals 8 of the heat generating member 4.

Further, the case 12 portion of the thermo assembly 22 is covered with the guard plate 16, and as a result, the guard plate 1
The temperature control knob 9 of the thermo-assembly 22 is exposed from a part of 6. Next, FIG. 3 is a side sectional view of a main part of a heating cooker 11 according to a second embodiment of the present invention, and FIG. 4 is a perspective view showing the appearance of FIG. 1 shows the case where the temperature control knob 9 of the first embodiment of FIG. 1 is changed from a dial type to a slide type, and the same parts in other examples 1 and 2 are shown with the same part numbers.

That is, the power supply output section 14 of the thermo assembly 22 is inserted into the heater terminal 8 of the heating element 4, the lower surface and the upper surface of the thermo assembly 22 are covered with the guard plate 16, and the thermo plate is partially covered with the thermo plate. Exposing the temperature control knob 9 of 7 upward is the same as in the first embodiment.

[0011]

As described above, according to the structure of the heating cooker of the present invention, the thermo assembly having the conventional structure is used, and the case of the thermo assembly is covered with the guard plate. , It prevents the user from removing the thermo-assembly, and as a result, the thermo-assembly's heater terminal can be connected / disconnected so that the shape change due to wear of the heater terminal and the thermo-assembly received. In addition, it is possible to prevent the occurrence of electrical troubles such as half-contact and the occurrence of electric shock fire.

On the other hand, although the thermo assembly is of a built-in type, it has a structure in which the conventional thermo assembly is simply covered with a guard plate, so that the cooker is assembled while the other parts are attached to the thermo. There is no processing, and mechanical and electrical instability can be eliminated. Furthermore, although the thermo assembly is built-in, the heat from the hot plate assembly is prevented by the thermo case, so it is not necessary to make the heat resistance of the members inside the thermostat more than necessary, and the cost can be reduced accordingly. Be peeled off.
