Abstract

PURPOSE:To prevent the flotation of an operation panel even if the operation panel is pushed when an outer lid is closed, by a method wherein a securing recess is provided at the end of an operation part-mounting recess which is formed on the surface of a lid body, and a catch part on one side of the operation paned is fitted with the securing recess, and the other side thereof is stuck on the operation part-mounting recess and they are sealed and fixed each other. CONSTITUTION:A recess 22 is formed at the end of an operation part-mounting recess 30 at the outside of a lid body 21, and a catch part 24 is formed on one side of an operation panel 23, and is fitted to the recess 22. The other side of the operation panel 23 is stuck and fixed on the operation part-mounting recess 30 on the lid body 21 with an adhesive member 28 such as a double coated tape. In such a way, the operation panel 23 is stuck on the operation- mounting recess 30, and hence it can be surely fixed, and does not fall by the expansion-and-contraction because of heat. Even if the operation panel is pushed when an outer lid is closed, the operation-mounting recess 30 receives the force in the direction of pushing, and hence the operation panel is not lifted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking appliance equipped with a switch on an operation panel.

BACKGROUND OF THE INVENTION In recent years, there has been a demand for cooking appliances equipped with microcomputers that are easy to use, do not malfunction, and are easy to operate.

Conventionally, this type of cooking device generally has a configuration as shown in FIG. 2, and the configuration will be explained below.

As shown in the figure, there is an upper frame 3 on the top of the main body 2 which has a built-in heating device (not shown), and is rotatably attached to the outer lid cover 5 or the main body 2 by a hinge shaft (not shown). Furthermore, it is biased in the opening direction by a hinge spring (not shown). A heat radiating plate 8 is fixed to the outer lid cover 5 through a pot gasket 7, and an outer lid 9 constituting an outer cover is provided on the upper part. A sole cover 10 is placed inside the outer lid 9.
This seal cover 10 is provided with
The board cover 12 is sealed and fixed through the seal cover 10. A control circuit board 15 on which a switch 13 and a display section 14 such as an LED are mounted is disposed inside the board cover 12, and a control circuit board 15 is mounted on the surface of the seal cover 10. A transparent sheet 16 that allows the display of the display section 14 to pass through is adhered to completely enclose the interior. The seal cover 10 has a transparent operation panel 17 sandwiched between it and the outer lid 9, and at the same time has a switch button 19 biased upwardly by a spring 18 movably attached thereto.
It is fixed to the outer cover 9 with screws.

Problems to be Solved by the Invention In such conventional cookers, the operation panel 17 has characters printed on the back of a transparent material such as acrylic resin.
A seal cover 10 and a large-area transparent sheet 16 are required to protect the control circuit board 15 by preventing steam heated by the heating device from entering and water from entering from the outer cover 9, resulting in high cost. The structure was as follows.

In addition, if you touch the operation panel 17 when closing the outer cover 9 by hand, it will rattle because there is no firm support in the direction of the presser foot, making it uncomfortable to use, and when closing the outer cover 9, stress is constantly applied. Moreover, there was a problem in that the thermal expansion and contraction of the resin material due to changes over time added to the tendency to cause rattling.

The present invention solves the above problem, and has a seal structure that protects the control circuit board from the ingress of water and steam, but does not rattle even when the operation panel is pressed when closing the outer cover, giving it a good usability. The outer lid does not float even if the stress of closing it is constantly applied, the sealing performance is ensured, a large-area operation panel is possible, and the number of parts is small, making it easy to assemble, which significantly reduces costs. The purpose is to provide equipment.

Means for Solving the Problems In order to achieve the above objects, the present invention provides an operating part mounting recess on the outer surface of the lid, a locking recess on one side of the operating part mounting recess, and a locking recess at one end of the operating panel. The claw portion of is fitted into the locking recess, and the other end side of the operation panel is attached with an adhesive,
It is glued and fixed to the operation part mounting recess of the lid.

Function The present invention has the above-mentioned configuration, in which one end of the operation panel is glued and fixed to the operation section mounting concave surface of the lid body.
Water and steam will not enter through the gap between the lid and the operation panel. In addition, the other end of the operation panel is fitted into a recess with a claw, so even if you press the operation panel when closing the outer cover, the pushing direction will be affected by the stress from the operation part mounting concave surface and will not lift up. Become.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG. In this embodiment, the same components as those shown in the above-mentioned conventional example are given the same reference numerals, and the explanation thereof will be omitted. The characteristic structure of this embodiment lies in the mounting structure of the operation panel section of the switch described in the conventional example. In other words, a recess 2 is provided at one end of the operation unit mounting recess 30 on the outside of the lid body 21.
2, a claw part 24 is provided at one end of the operation panel 23, and the claw part 24 is fitted into the recess 22, and the other end of the operation panel 23 is attached to the cover body 21 using an adhesive 28 such as double-sided tape. It is attached by adhering it to the mounting concave surface 30. The switch operating body 25 is a switch button 26.
It consists of a flange surface 27 connected to the flange surface 27, and is integrally molded from an elastic material such as synthetic resin or rubber. body 21 and operation panel 2
A flange surface 27 is sandwiched in the gap between the switch 3 and the switch 13 via an adhesive 28, and when the switch button 26 is pressed, the operating lip 31 or the switch 13 is pressed to operate.

According to the above configuration, the claw portion 24 at one end of the operation panel 23 is fitted into the recess 22, and the other end is attached to the operation portion mounting concave surface 30 with the adhesive 28, so that the operation panel 23 can be securely fixed.
It has the effect of not falling off due to expansion and contraction due to heat.

Effects of the Invention As is clear from the above description of the embodiments, the present invention provides a claw portion at one end of the operation panel, and engages the claw portion with a recess provided at one end of the operation portion mounting concave surface of the upper surface of the lid. By attaching the other end of the operation panel to the operation unit mounting concave surface with an adhesive, the operation panel can be securely fixed to the top of the lid and will not fall off due to expansion and contraction due to heat. , improves sealing performance and prevents water vapor and water from penetrating.
Furthermore, the practical value is remarkable as it can reduce the number of parts.
