Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rice cooker equipped with a control board.

[Conventional technology]

FIG. 3 is a sectional view of the main parts of a conventional rice cooker.
In the figure, 1 is a control board to which electronic parts etc. are attached, 2 is a board box attached to the outer case 4 of the rice cooker body via a gasket 3, and the control board 1 is attached to the board box 2 by screws (not shown). ) etc. Note that the outer case 4 is a resin molded product.

5 is the inner pot, 6 is the rice that goes into the inner pot 5, 7 is the water droplet that adhered to the rice 6 and when it is boiled, 8 is the heater installed at the bottom of the inner pot 5, 9 is the heater 8 This is a stream of steam that is generated by being heated. 10 is an outer pot provided between the inner pot 5 and the outer case 4, 11 is an outer lid, 12 is a partition plate, 13 is a shaft provided on the partition plate 12, and 14 is supported by the shaft 13. Inner lid 15 is inner lid 14 and shaft 1
A lid seal 16 seals between the outer case 4 and the outer case 4, and 16 is a support ring provided on the outer periphery of the upper part of the outer case 4. 17 is a lower case forming the lower part of the outer case 4; 18 is a heat sensitive body; 19 is a spring that supports the heat sensitive body 18; and 20 is a spring support plate provided on the bottom surface of the spring 19.

In such a conventional rice cooker, after washing rice 6 in an inner pot 5 and adding an appropriate amount of water, the rice is stored in an outer pot 10, and an outer lid 11 with an inner lid 14 attached thereto.
Seal from above. Then, when the heater 8 is energized to cook rice, the water droplets 7 that adhere to the outer surface of the inner pot 5 during rice washing are heated by the heater 8, and turn into water vapor inside the main body, that is, the space inside the outer case 4. G
It fills the air, moves from the gap to the upper part of the body, and tries to escape to the outside air. At this time, since the board box 2 is sealed by the packing 3,
Measures are taken to prevent steam from flowing into the control board 1.

[Problem that the invention seeks to solve]

In the conventional rice cooker as described above, water vapor generated in the space G inside the outer case 4 rises and rises to the top.
Since the packing 3 was used to prevent the control board 1 from entering the board box 2 through the gaps and adhering to the control board 1 and deteriorating the electrical characteristics, the number of parts increased and the assembly became complicated.

Further, when the packing 3 is used for a long period of time, the packing 3 is constantly exposed to water vapor, so that it deteriorates and its sealing function is reduced, and there is also a fear that the vapor may enter the inside of the substrate box 2.

This invention was made to solve the above-mentioned problems, and provides a rice cooker that can prevent steam from adhering to the control board and eliminate parts such as a board mounting box and packing. The purpose is to

[Means to solve the problem]

The rice cooker according to the present invention has a wall surface consisting of an upper wall and a side wall integrally molded with the upper wall on the side surface of the outer case of the main body, and a control panel section consisting of a recess with an open front surface, and It is equipped with a control panel that covers the opening of the panel part in the same plane as the outer case, and a control board that is placed in a recess of the control panel part and has electronic components attached thereto, and a space is provided inside the main body from the recess. The upper wall of the recess and the outer case are integrally molded.

[Effect]

The rice cooker according to the present invention has the upper wall of the concave part of the control panel section in which the control board is disposed inside and the outer case integrally molded.
To prevent steam generated inside a main body from entering into a control panel part from above a recess, to protect a control board from steam, and to prevent an adverse effect on the control board.

[Embodiments of the invention]

FIG. 1 is a cross-sectional view of the main parts of an embodiment of the present invention.
FIG. 2 is an exploded perspective view of the main parts. Note that the same or equivalent parts as in the conventional example shown in FIG. 3 are given the same reference numerals, and the explanation thereof will be omitted.

In the figure, 21 indicates the upper wall 21b and the upper wall 2
1b and a side wall 21c integrally molded, the control panel section has a recess 21a with an open front surface, and the wall surface 21d including the upper wall 21b of the recess 21a is integrally molded with the side surface of the outer case 4. has been done. Reference numeral 22 denotes a control panel that covers the opening of the control panel section 21 in the same plane as the outer case 4. The control board 1 is disposed within the recess 21a of the control panel section 21, and the control board 1 is mounted on the wall surface 2 of the recess 21a.
1d In particular, the upper wall 21b prevents water vapor generated inside the rice cooker main body, that is, in the space G inside the outer case 4, from entering the recess 21a from above the recess 21a.

In the rice cooker configured as described above, an inner pot 5 containing rice and water is housed in an outer pot 10, and the outer pot 10 is sealed from above with an outer lid 11. When the heater 8 is energized to cook rice, the water droplets 7 that adhere to the outer surface of the inner pot 5 during rice washing are heated by the heater 8 and turn into steam, which fills the space G inside the outer case 4. It escapes to the outside air through the upper gap.

At this time, the recess 21 of the control panel section 21
Since the upper wall 21b of a is integrally molded with the side surface of the outer case 4, the control panel section 21 is almost completely sealed with the space G in which steam is generated by the recessed section 21a, preventing steam from entering the control panel section 21. In addition, it is possible to protect the control board 1 from steam.

〔Effect of the invention〕

As described above, according to the present invention, the upper wall of the concave part of the control panel part and the side surface of the outer case are integrally molded, thereby preventing steam generated inside the main body from adhering to the control board, thereby preventing short circuits, etc. Electrical disturbances can be prevented, and there is no need to use conventional gaskets, etc., making it possible to obtain a rice cooker that is easy to assemble and is inexpensive.
