Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking appliance such as a hot plate or pan that uses a connection plug.

Conventionally, in the case of a cooking device such as a hot plate, the end of the sheathed heater was led out to the back end of the container, a power supply horn was connected to the tip, and a heat-sensitive rod of a connection plug was installed in the middle of the power supply horn. An insertion section is provided, the insertion section and the end of the sheathed heater are held at a constant distance by a pedestal, and the power source angle is protected by a protective member that covers the pedestal. This protective member was attached to the base with two fixing screws. However, in recent years, with the simplification of the assembly process, the protective member has come to be attached using a single screw. This has the drawback of making it difficult to insert the connection plug.

The present invention was made to eliminate the above-mentioned drawbacks, and by providing a cut-and-raise piece that engages with the side surface of the pedestal on the contact surface of the protection member that contacts the pedestal, the protection member is fixed with a single screw. To provide a cooking appliance whose positioning is reliable without tilting to the left or right even in the case of an accident, and which does not hinder the insertion of a connection plug.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, details of the present invention will be explained with reference to the drawings for one embodiment. Reference numeral 1 denotes a round hot plate device body, and a power connection plug (not shown), such as a thermomaster, is attached to one end of the back surface 1' of the device.
Ends 3a, 3a of a sheathed heater 3 disposed on the heat-sensitive rod insertion portion 2 and the back surface 1' are positioned on both sides of the insertion portion 2 by welding or soldering. Reference numeral 4 designates a pedestal, with a clamping portion 4a in the center that conforms to the shape of the insertion portion 2, and semicircular support portions 4 that are appropriately spaced on both sides and also conforming to the shape of the heater end portion 3a.
b, 4b, the insertion part 2 and the heater end part 3
a, 3a are integrally supported and their attachment positions relative to the back surface 1' of the container are restricted. Reference numeral 5 designates a protective member, which is formed into a rectangular tube shape, with a part of its side surface cut out so that its leg pieces 5a, 5a abut against the back surface 1' of the body, and a cylindrical portion 5b is provided protruding from the side surface of the body. hand,
As shown in FIG. 3, the power horns 7, 7 attached to the heater ends 3a, 3a via insulating rings 6, 6 are protected. The side surface left by the notch becomes a contact surface 5c that comes into contact with the pedestal 4, and this contact surface 5c is provided with cut and raised pieces 8, 8 that engage with both side surfaces of the pedestal 4. There is. Reference numeral 9 denotes a fixing element, which is inserted through a hole 10 provided approximately in the center of the abutment surface 5c and is inserted into a screw hole 11 of the base 4.
The protection member 5 is fixed to the pedestal 4 by screws. 1
2 is a mounting seat, and 13 is a cover.

Next, the assembly procedure will be described. First, insertion section 2
and the end portions 3a, 3a of the sheathed heater are respectively fitted or abutted on the clamping portion 4a and the supporting portion 4b of the base 4 to regulate their mounting position, and then the back surface 1 of the sheathed heater is welded or brazed. ’ to be attached. And the heater end 3 whose position is regulated
Power supply angles 7, 7 may be connected to a, 3a via an insulating ring 6. Next, the contact surface 5c of the protection member 5 is brought into contact with the back surface of the pedestal 4, and the cut and raised pieces 8, 8
is engaged with the side surface of the pedestal 4, and the supporting portion 4b
is fixed to the back surface 1' of the vessel by brazing.
Finally, when the fastener 9 is screwed into the screw hole 11 of the pedestal 4 through the hole 10 of the protection member, the protection member 5 has one fastener 9 for the pedestal 4 and the cut-and-raised pieces 8, 8. It can be securely fixed by engagement.

As described in detail above, the present invention includes a device main body in which a heat-sensitive rod insertion part and the ends of a sheathed heater are positioned on both sides thereof, and the insertion part and heater ends are integrally supported to regulate their mounting position. a pedestal, a protection member having a contact surface to the pedestal, and a cut-and-raised piece provided on the former contact surface that engages with the side surface of the pedestal; Since this cooker is equipped with a fixing element that is fixed to the protective member, only one fixing element is required, making it possible to save materials and improve workability.Moreover, even if an external force is applied to the protective member, it will not break off like a cut-and-raised piece. It has the excellent advantage that it does not tilt due to engagement with the pedestal, is securely fixed, and does not hinder insertion of the connection plug.
