An operation unit 11 is provided inside the lid body 3. This operation unit 11
Among them, 12 is a waterproof wall, and this waterproof wall 12 is erected on the inner plate 5, and is formed by partitioning the electrical component chamber 13 in the lid cover 6 by this waterproof wall 12. Reference numeral 14 denotes a switch 15 for operation, a display 16 for display, and the electronic component 1
7 is a circuit board, and this circuit board 14 is an electrical equipment room 1
The bosses 3 are housed in the housing 3 and are fixed to a plurality of bosses projecting downward on the outer lid 4 with screws 18 or the like.

Further, the switch 15 and the indicator 16 are exposed in the openings 19 and 20 formed in the outer wall 4, respectively. Two
1 is a display sheet, and this display sheet 21 is the opening 1
It is attached to the outer lid 4 by a double-sided adhesive tape or the like so as to cover 9 and 20.

SUMMARY OF THE INVENTION However, in such a conventional configuration, the electronic component 1
Around the electrical component room 13 that houses the circuit board 14 in which the circuit board 14 in which the circuit board 7 is housed
It must be sealed with, for example, EP rubber which is impermeable to moisture. In this case, when the control lead wire tangential to the circuit board 14 passes through the rubber, there is a slight gap between the lead wire and the lead wire. May occur, and moisture in the air or infiltration of heated steam during cooking may occur from this gap, which may damage the electronic component.

Further, when the EP rubber is replaced with a water-impermeable and soft material such as butyl rubber, the lead wire portion can be sealed, but on the other hand, once assembled, it is difficult to remove and the component can be reused. Butyl rubber adheres to the
It was difficult to reuse.

The present invention solves such conventional problems, and an object thereof is to provide a cooking utensil having excellent moisture resistance, serviceability, and reusability.

Means for Solving the Problems In order to solve the above problems, the present invention provides an outer shell member of an adjusting instrument body, a cover member fitted to the outer shell member, and an electronic component housed inside the cover member. A circuit board having components and a heating element housed inside the cover member, and pressure-bonded between the groove provided on the outer shell member and the rib provided on the cover member with, for example, EP rubber interposed. The lead wire connected to the circuit board is passed through a through hole provided in the cover member, and the through hole is sealed to hermetically seal the inside of the cover member.

With such a configuration, the entire circumference of the cover member accommodating the rotary substrate is sealed with, for example, EP rubber, and the lead wire passage portion is sealed with, for example, butyl rubber, so that the inside of the cover member is sealed. Since the inside of the cover member is located in the still air, as a result, it is less likely to be adversely affected by the surrounding moisture and hot air, and the quality can be improved. Further, even if dew condensation inside the cover member occurs due to a change in room temperature or the like, moisture can be eliminated by transmitting the heat to the heat generating element, and the clouding of the display portion can be prevented.

Further, since butyl rubber is used only locally, the range of butyl rubber attached to parts can be minimized, and therefore reusability and serviceability after assembly and disassembly can be improved.

Example Hereinafter, a first example of the present invention will be described with reference to FIG.

In FIG. 1, reference numeral 31 is a main body of an adjusting instrument, and a pan 32 is detachably installed in the main body 31 of the adjusting instrument. 33
Is a lid body that is rotatably supported by one side of the upper surface opening of the adjusting device main body 31 and covers the upper surface opening. This lid 33 has a resin outer lid 34 forming the upper surface and a lower surface similarly. It is configured with a lid cover 35 that constitutes it. Reference numeral 36 denotes a handle portion provided on the outer lid 34, and the handle portion 36 is provided with a handle cover 37 that covers the upper surface. Three
8 is a switch 39 for operation inside, and a display 4 for display.
0 and a display board cover accommodating a circuit board 42 having an electronic component 41. EP rubber is interposed as a display plate packing 46 between the groove portion 43 provided in the display plate cover 38 and the rib 45 provided upright on the inner top surface of the display plate portion 44 of the outer lid 34, and is tightened by the screw A47. It is fixed.
A heating element 48 is fixed to the outer lid 34 by a support fitting 49.

Reference numeral 50 is a passage hole for passing the lead wire 51 connected to the circuit board 42 of the display plate cover 38, and the lower surface opening thereof is covered with the cap 52. The cap 52 is provided with a groove portion 53, and the display plate cover 38 is provided with the groove portion 5.
The ribs 54 corresponding to No. 3 are arranged in parallel, butyl rubber is interposed as a cap seal 55, and the ribs are fixed by tightening with screws. Reference numeral 56 is a film-shaped display sheet, and the display sheet 56 is attached by a double-sided adhesive tape or the like so as to cover the opening 57 provided at a position corresponding to the display 40 section and the switch 39 section of the display plate section 44. Has been done.

The operation of the configuration shown in FIG. 1 will be described below.
The display plate portion 44 and the display plate cover 38 of the outer lid 34 are sealed at their entire peripheries by a display plate packing 46, and the lead wires 51 connected to the circuit board 42 are through holes provided in the display plate cover 38. It is passed through from 50 and is sealed by a cap 52 and a cap seal 55. Since the cap seal 55 is made of soft butyl rubber, the butyl rubber also enters the gaps between the lead wires 51, and as a result, sufficient sealing performance can be obtained.

Further, the display sheet 56 covers the opening 57 of the display plate portion 44. Therefore, the inside of the display plate cover 38 accommodating the circuit board 42 can be secured in a hermetically sealed state having a static air layer, so that the thermal conductivity is low and the heat insulating property is high. Further, since the rubber impermeable to moisture is used, it is possible to prevent the heated steam or the like that has entered the outer lid 34 from entering the display plate cover 38.

In addition, by energizing the heating element 48 against dew condensation in the display plate cover 38 caused by a change in room temperature or the like, moisture can be removed and the display sheet 56 can be prevented from fogging.

Effects of the Invention According to the present invention, as is clear from the description of the above embodiments,
It is possible to secure sufficient sealing properties against moisture such as heated steam, and also to obtain a heat insulating effect, so it is possible to minimize the effect on the circuit board and improve quality. It is possible to prevent dew condensation caused by a change in room temperature.

Also, since butyl rubber is only used locally, it can be relatively easily re-used after assembly and disassembly,
The serviceability can be improved.
