Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cooking appliance such as a rice cooker used in general households.

BACKGROUND ART Conventional cooking appliances, such as rice cookers, have a structure as shown in Figure 2.

That is, a temperature sensor 1 such as a thermal reed switch is fastened to the tip of a fixture 2 with a screw 3, and is in contact with the outer surface of the outer pot 4. Mounting tool 2
is fastened to the outer bottom surface of the outer pot 4 with screws 6 together with a terminal base 5 which serves as a relay for wiring. 7 is a heat-retaining heating element attached to the outer surface of the upper part of the outer pot 4; the temperature detector 1 detects the heat generated by the heat-retaining heating element 7 via the outer pot 4, and detects the heat generated by the heat-retaining heating element 7; 7 is controlled to keep the temperature of the contents of the inner pot 8 constant.

Problems to be Solved by the Invention However, in such a conventional configuration, the fixture 2
If the shape of the temperature sensor 1 is deformed when attached to the outer pot 4 or during transportation, the temperature sensor 1 itself separates from the outer surface of the outer pot 4, causing the problem that the temperature on the side surface of the outer pot 4 cannot be accurately detected. It was hot.

The present invention solves these problems,
Even if the attachment of the temperature sensor is deformed, the temperature sensor does not separate from the outer pot, and the temperature on the side surface of the outer pot can be accurately detected.

Means for Solving the Problems In order to solve the above conventional problems, the present invention has the following features:
A protrusion is provided on the upper frame provided at the upper opening of the outer pot,
The fitting is pushed inward.

Effect: According to this configuration, even if the fitting is deformed, the temperature sensor acts so as to come into pressure contact with the side surface of the outer pot, so that it will not come off from the outer pot.

Therefore, the temperature on the side surface of the outer pot can be precisely detected and controlled accurately.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIG. In the figure, 11 is the cooking device main body, 12
13 is an upper frame provided at the upper opening of the main body 11;
14 is a heating element provided at the bottom of the outer pot 13; 15 is a heating element 1;
This inner pot is removably placed on top of 4.
5 is installed in the outer pot 13 so as to be freely inserted and removed. 1
6 is a lid covering the upper opening of the inner pot 15; 17 is a moisturizing heating element attached to the entire circumference of the upper side of the outer pot 13;
8 is a heat insulating material interposed between the main body 11 and the outer pot 13, and 19 is a cooking sensor that comes into contact with the bottom of the inner pot 15 to detect the temperature.

A temperature sensor 20 such as a thermal reed switch is fastened to a fixture 21 with a screw 22 and is in contact with the outer surface of the outer pot 13.

The fixture 21 is fastened to the outer bottom surface of the outer pot 13 with screws 24 together with a terminal base 23 that serves as a relay for wiring.

25 is a projection of the upper frame 12, and the tip 26 of the fixture 21 is pressed against the inside of the projection 25.

As is clear from the above structure, in this embodiment, the tip 26 of the fitting 21 is pressed against the inside of the protrusion 25 of the upper frame 12 that is fixed to the outer pot 13, so that the fitting 21 is The temperature sensor 20 is connected to the outer pot 15 using the pressure contact part (A part) with the upper frame 12 as a fulcrum.
The contact part (B part) with the outer surface of the part receives a pressing action. Further, since the part B is close to the part A, even if the shape of the fixture 21 is deformed, the temperature sensor 20 will not come off from the outer surface of the outer pot 15.

Effects of the Invention As described above, according to the present invention, the temperature sensor can reliably come into contact with the outer surface of the outer pot even if its attachment is deformed, so that the temperature state of the outer pot can be accurately detected. This makes it possible to maintain good temperature control characteristics.
