Description

[Detailed Description of the Invention] The present invention relates to a heating cooker having a structure in which an operating section of a switch device protrudes from an opening of a switch cover provided in a heating cooker main body.

Traditionally, in cooking appliances such as rice cookers, the operating part of the switch lever, which is movable up and down, is connected to the heating cooking appliance body, which has a switch device inside to control the energization and disconnection of the heater, etc. A switch cover is provided on the side of the heating cooker body having an opening through which the operating section is passed, and the operating section is made to protrude from the opening. is moved up and down within the opening of the switch cover to control the switch device. However, in this type of heating cooker, when the switch cover is attached to the main body of the heating cooker, it may be installed with the switch cover tilted or shifted from the normal installation position, and as a result, the operating part may be attached to the opening edge of the switch cover. There have been problems such as contact with each other and making it impossible to operate, and a large gap between the knob and the edge of the opening, which spoils the appearance. Furthermore, if this is to be prevented, the gap between the opening edge and the knob must be delicately adjusted when attaching the switch cover, which is troublesome.

The present invention was developed in view of the above circumstances, and its purpose is to reliably mount the switch cover in the correct mounting position, thereby reliably preventing the switch lever from becoming inoperable. Furthermore, it is an object of the present invention to provide a heating cooker which can have a good appearance and can also facilitate the installation work of a switch cover.

An embodiment in which the present invention is applied to a rice cooker will be described below with reference to the drawings. 1 is the main body of the rice cooker, which is a heating cooker; 2 is a substantially cylindrical outer case that forms the outer shell; 3 is a bottom frame fitted to the lower part of the outer case 1; 4 is arranged inside the outer case 1. Inner case, 5
6 is a heat insulating material placed between the outer case 2 and the inner case 4; 6 is a pot removably attached to the inner case 4; 7 is an electric heater for cooking rice provided at the inner bottom of the inner case 4. , 8 is a lid rotatably provided on the outer case 2 via a hinge part 9, 10 is a handle attached to the lid 9, 11 is a clamp provided on the handle 10, and 12 is a lid of the inner case 4. A support 13 is attached to the bottom of the support, and a temperature sensor 13 is attached to the support 12. The temperature sensor 13 is pressed against the lower surface of the bottom of the pot 6 to sense the bottom temperature of the pot 6. This is a well-known structure in which it automatically separates from the bottom of the pot 6 when the temperature reaches a predetermined temperature or higher. 14 is a switch device, which includes a normally closed micro switch 15 and a switch base 1 made of a steel plate that fixes the micro switch 15.
It consists of 6. The switch base 16 has a hook-shaped positioning protrusion 1 on the upper right edge.
7, 17, and a screw seat 18 on the upper left edge. The protrusion 17 is fitted into support holes 19, 19 formed in the outer case 2 so as to protrude from inside the outer case 2, and the screw seat 18 is fixed to the support 12 on the lower surface of the inner case 4 with a screw 20. Thus, the switch base 16 is disposed within the rice cooker main body 1. On the other hand, the micro switch 15 is screwed to a mounting portion 21 formed on the switch base 16. Reference numeral 22 denotes a switch lever rotatably mounted on the switch base 16, and a knob 23 serving as an operating portion is attached to one end of the switch lever.
3 protrudes from the bottom frame 3 of the rice cooker main body 1. The other end of the switch lever 22 is a temperature sensor 13.
The actuator 13a is connected to the actuator 13a. As a result, the switch lever 22 presses the temperature sensor 13 against the bottom of the pot 6 by moving the knob 23 downward, and also closes the micro switch 15, so that the temperature sensor 13 operates based on the temperature sensing operation. When separated from the pot 6, the micro switch 15 is opened to stop the predetermined heating operation. Reference numeral 24 denotes a plastic switch cover, which is sized to cover the knob 23 of the switch lever 22 and the entire area above it. A rectangular opening 25 is formed in a portion corresponding to the knob 23, and this opening 25 is formed in a portion corresponding to the knob 23.
5 is above the protrusion 1 of the switch base 16.
Protrusions 26 and 2 serving as positioning portions corresponding to 7 and 17
6 is formed. The distance L between the opposing protrusions 26, 26 is set to be approximately equal to the distance l between the protrusions 17, 17. In addition, 27, 27 is a protrusion formed at the lower end of the switch cover 24, 28 is a lamp accommodating part formed approximately at the center of the switch cover 24, 29 is a switch holding piece formed at the upper part thereof, and 30 is a switch cover 24. This is a screw insertion hole formed at the upper end of 24. Then switch cover 24
is attached to the rice cooker main body 1 with the protrusion 27 fitted into the hole 3a formed in the bottom frame 3 and the upper end portion screwed to the upper end portion of the outer case 2.
In this installation, the knob 23 is passed through the opening 25, and the ends of the protrusions 26, 26 are attached to the side surfaces of the protrusions 17, 17 protruding from the hole 19 of the outer case 2.
After positioning the switch cover 24 by bringing them into contact as shown in the figure, the above-mentioned fitting and screwing are performed. Therefore, when the switch cover 24 is installed, there is no possibility that the switch cover 24 will be installed in a tilted or deviated state.

As described above, according to this embodiment, the switch cover 2
4 is provided with a protrusion 26 that positions the switch cover 24 by coming into contact with the protrusion 17 of the switch base 16 that is a part of the switch device 14, so that the switch cover 24 can be reliably installed in the normal installation state. Therefore, the knob 2 passed through the opening 25
It is possible to prevent problems such as vertical movement of the knob 3 being obstructed by the edge of the opening 25, and the installation work can be carried out without the need for delicate adjustment of the gap between the edge of the opening 25 and the knob 23. It is easy to perform and looks good, and the gap between the both side edges of the opening 25 and the knob 23 can be made much smaller than that of the conventional one, which also improves the look.
Further, according to this embodiment, the positioning protrusion 17
Since it is also used as a mounting member for attaching the switch base 16, the structure can be simplified.Moreover, in the case of this embodiment, since the protrusion 17 is made to protrude from the outer case 2, the protrusion 17 can also be used as a mounting member. However, engagement with the projecting piece 26 can be performed easily.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with various modifications within the scope of the invention, for example, it can be widely applied not only to rice cookers but to heating cookers in general.

As explained above, the present invention allows the switch cover to be reliably installed in the correct mounting position, thereby reliably preventing the switch lever from becoming inoperable, and also improving the appearance of the switch. It is possible to provide a heating cooker in which the work of attaching a cover is made easy.
