Description

[Detailed description of the invention] Industrial applications The present invention relates to a rice cooker.

Conventional technology Generally speaking, this type of rice cooker is
As shown in Publication No. 37053, it had a configuration as shown in FIG.

In FIG. 3, 1 is a rice cooker main body (hereinafter referred to as main body), and inside this main body 1, a bottomed cylindrical protective frame 2 was provided. A heater section 3 was attached to the inner bottom of the protective frame 2, and a hole 5 was provided in the center of the heater section 3 through which the thermal response device 4 was exposed. A bottomed cylindrical pot 6 whose bottom portion is removably placed on the heater portion 3 was provided in the protective frame 2 . The thermal response device 4 is disposed at the bottom of the protective frame 2 so as to be movable up and down, and comes into contact with the center of the bottom back surface of the pot 6 through a hole 5 provided in the center of the heater section 3 to adjust the temperature of the pot 6. is detected, and the energization of the heater section 3 is controlled. A lever support member 7 is provided at the inner bottom of the main body 1, and a lever 8 is attached to the lever support member 7 so as to perform a seesaw action. was configured to do so. The lever 8
One end was connected to the thermally responsive device 4, and the other end was connected to a switch button 10 disposed on the lower outer surface of the main body 1.

In the above configuration, when the switch button 10 is pushed downward, the thermally responsive device 4 provided at the other end of the lever 8 is pushed upward, and this thermally responsive device 4 comes into contact with the bottom of the pot 6. The heater section 3
is energized in conjunction with the operation of this switch button 10. The pot 6 is heated by energizing the heater section 3.
As the heating progresses and the bottom temperature of the pot 6 reaches a predetermined temperature or higher, the heat-responsive device 4 detects this bottom surface temperature, operates, and moves downward. This results in
One end of the lever 8 is pushed down and a switch button 10 provided at the other end of the lever 8 is pushed up to turn it off.

Further, the supply of electricity to the heater section 3 is also interrupted in conjunction with this switch button 10.

Problems to be Solved by the Invention However, in the conventional configuration described above, the switch button 10 is disposed on the lower outer surface of the main body 1, so if an article is placed near the switch button 10, the switch button When the switch button 10 is turned off, the object prevents the switch button 10 from turning off, and as a result, the heater section 3 continues to be energized, causing an abnormality. However, in order to prevent this, conventionally the switch button 10 is arranged so that it does not protrude from the outer surface of the main body 1.
0 is stored in the main body 1, and as a result, it is difficult to tell from the outside whether the switch button 10 is in the on or off state, and furthermore, when the rice cooker is placed on the floor or table. Another problem was that the switch button 10 was located far from the user's hand, making it inconvenient to use.

The present invention solves the above conventional problems,
The purpose is to provide a rice cooker with excellent operability.

Means for Solving the Problems In order to achieve the above object, the rice cooker of the present invention has the following features:
A rice cooker main body, a bottomed cylindrical protective frame installed inside the rice cooker main body, a heater section arranged at the inner bottom of the protective frame, and a heater section that can be detachably attached to the heater section inside the protective frame. A cylindrical pot with a bottom is placed thereon, and a cylindrical pot is arranged at the bottom of the protective frame so as to be movable up and down, and faces a hole provided in the center of the heater section and comes into contact with the bottom of the pot. a heat-responsive device that detects the temperature of the pot and controls the energization of the heater section; a lever that is interlocked with the heat-responsive device is pivotally supported at the bottom of the protective frame in a seesaw motion; A switch button is slidably disposed on the upper part of the device body, and the switch button and the lever are connected via a connecting plate, and the connecting part between the lever and the connecting plate is connected to either the lever or the connecting plate. A groove is provided at one end, and a notch is provided at the tip corresponding to the groove through a rotation shaft that is a center of rotation between the lever and the connecting plate, and either the lever or the connecting plate The other end includes a fitting claw that is slidably fitted into the groove, a rotating claw that faces the fitting claw and comes into contact with the rotating shaft, and the rotating claw and the above-mentioned rotating claw. An arc-shaped gap portion is provided between the fitting claw and the notch portion.

Function According to the above configuration, even if the switch button is almost housed inside the rice cooker main body, it is located at the top of the rice cooker main body, so it is easy to visually see the operating state of the switch button. It can be easily confirmed. Furthermore, when operating the switch button, it is easy to operate because it is close to the hand.
Furthermore, the lever and the connecting plate are connected by fitting the fitting claw into the groove, bringing the rotating claw into contact with the rotating shaft, and bringing the notch into contact with the gap. , making the connection work very easy.
