Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cooker that heats a rice pan that is detachably housed in a rice cooker body to cook rice.

[0002]

2. Description of the Related Art Conventionally, this type of rice cooker has been constructed as shown in FIG. The configuration will be described below.

As shown in FIG. 4, the rice cooker main body 31 has a pan 32 with a flange detachably accommodated therein, and a lid body in which an upper end is openable and the other end is pivotally supported by a hinge shaft 33. 34 is rotatably provided. A pot packing 35 is provided on the lower surface of the lid 34 so as to face the flange. Further, the lid 34 is provided with a steam discharge flow path 36 that communicates the space inside the pan 32 with the outside, and steam generated during rice cooking is discharged to the outside of the rice cooker main body 31 through the steam discharge flow path 36. It is composed.

A heating coil 37 for inductively heating the pan 32 is provided in the rice cooker main body 31.
A display operation unit 38 that displays the operation and operating state of the device is provided in front of. The display operation unit 38 is fixed to the substrate base 40 together with the heating control unit 39 that is electrically connected, and is fixed to the rice cooker body 31 from the inside of the rice cooker body 31 via the substrate base 40.

Further, each tact switch 41 on the display / operation unit 38 is provided with a synthetic resin key top 42, and the outer surface thereof is covered with an operation panel 43. By pressing the switch portion of the operation panel 43 during operation, the tact switch 41 of the display operation portion 38 is pushed down via the key top 42, an electric signal is sent to the heating control portion 39, and the energization state of the heating coil 37 is controlled. It is composed.

[0006]

However, in the rice cooker as described above, since the display operation portion 38 is in communication with the inside of the rice cooker body 31 through the opening provided in the rice cooker body 31, this occurs during rice cooking. The heat stays inside the rice cooker main body 31 and is directly affected by the temperature rise inside the rice cooker main body 31 and the temperature of the display operation unit 38 rises. Cockroaches and the like that have entered the inside directly enter the display unit 38, so that there is a problem that they can be seen from the outside.

Therefore, in order to prevent the temperature of the display / operation unit 38 from rising, it is necessary to use electronic parts having high heat resistance, and cockroaches or the like that have entered the inside can be seen from the outside. By arranging the display operation unit 38 vertically, it is possible to prevent cockroaches from staying in the display operation unit 38, and to use a substrate coated with a cockroach repellent. The closer the part 38 is to the vertical direction, the worse the operability becomes, and when applying a drug, there is a problem of persistence of effect and a problem of cost, which is an essential solution. There was a problem that it could not be a solution.

The positional relationship among the operation panel 43, the key tops 42, and the display operation unit 38 is important as a factor that determines the operating force of the switches of the display operation unit 38. Then, since the display operation unit 38 is fixed to the rice cooker main body 31 via the substrate base 40,
There is a problem that the positional relationship with the operation panel 43 directly attached to the rice cooker main body 31 is not stable, and therefore the operation force of the switch is not stable.

The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to prevent invasion of cockroaches or the like into the display operation section and to stabilize the key operation force to improve the operation feeling.

[0010]

In order to achieve the above object, the present invention is configured such that a pan detachably housed in a rice cooker body is heated by a heating means and the top surface of the rice cooker body is covered with a lid. The rice cooker main body has a concave portion for holding the display operation unit, and the display operation unit is arranged in a space separated from the inside of the rice cooker main body.

This makes it possible to prevent cockroaches and the like from entering the display operation section and stabilize the key operation force to improve the operation feeling.

[0012]
