Description

  The present invention relates to a heating device including an electronic component such as a liquid crystal panel.

  In a heating device such as a rice cooker, an operation panel portion is formed on the device main body or the lid. The operation panel unit includes a plurality of switches as input means, and a liquid crystal panel that displays an operation state and an operation state of the device. Electronic components such as a switch and a liquid crystal panel are mounted on a display substrate, and the display substrate is disposed in an electronic component housing portion formed in the exterior body of the device main body or the lid.

  It cannot be denied that air containing moisture (humidity) in the factory enters the electronic component housing portion during assembly. In addition, some moisture may ooze from the display substrate on which the electrical components are mounted. When the moisture in the electronic component housing part is vaporized by the temperature rise, the display surface of the liquid crystal panel may be clouded. Therefore, a desiccant for adsorbing moisture is disposed in the electronic component housing portion. However, a heat-generating component that is heated by energization is mounted in the exterior body. When the desiccant is heated by this heat-generating component, the adsorbed moisture is released and eventually the liquid crystal panel is fogged.

  Patent Document 1 describes a rice cooker in which an electronic component housing portion is disposed on a lid and a lid heater is disposed so that heat is conducted to the electronic component housing portion. In addition, a communication path member that communicates the inside and the outside is disposed in the electronic component housing portion. In this rice cooker, the desiccant is heated by the heat of the lid heater, and the adsorbed moisture is released into the electronic component housing portion. And the adsorption | suction performance of a desiccant is reproduced | regenerated by discharge | releasing a water | moisture content outside the electronic component accommodating part through a communicating path member.

  However, the rice cooker of patent document 1 may cloud a liquid crystal panel with the water | moisture content discharge | released from the desiccant by heating. Further, when the inside of the electronic component housing is naturally cooled after heating, external air flows in. Since the air is air around the rice cooker and contains a large amount of moisture (steam) by rice cooking, there is a possibility that the total amount of moisture in the electronic component housing portion increases. It should be noted that the influence of moisture in the electronic component housing portion extends not only to the liquid crystal panel but also to all electronic components (elements) mounted on the display substrate.

A convex portion 50 disposed in the seal member disposition groove 46 is provided on the inner peripheral side of the operation panel portion 47. By assembling the decorative panel 32 to the cover body 31, the convex portion 50 is pressed against the seal member 45 in the seal member disposition portion, and the inside of the panel housing portion 42 is sealed.

  The panel housing part 42 is provided with a wiring port 51 at one corner on the back side. A locking part 52 and a screwing part 53 are provided around the wiring port 51. A flat cable 54 for electrically connecting the operation board 41 is inserted into the arrangement port and is airtightly closed by a shielding member 55. The shielding member 55 includes a locking step portion 56 that is locked to the locking portion 52 and a screw insertion portion 57 that corresponds to the screwing portion 53. By arranging the shielding member 55 and screwing it, the flat cable 54 is pressed and the gas flow into the panel housing portion 42 is prevented. In addition, when the clearance gap between the wiring port 51, the flat cable 54, and the shielding member 55 is large and gas can distribute | circulate, it seals by arrange | positioning a sealing member.

  A pressure release tube 58 is introduced into the panel housing portion 42 from the wiring port 51 together with the flat cable 54. The pressure release tube 58 releases the pressure (air) when the sealed panel housing portion 42 is heated and the air in the panel housing portion 42 is thermally expanded. The depressurizing tube 58 is set to an inner diameter that does not cause convection of gas between the inside and outside of the panel housing portion 42. Further, when the gas in the panel housing portion 42 (hereinafter referred to as “existing gas”) is allowed to escape to the outside due to thermal expansion, the entire length is set such that the existing gas does not flow out from the tip of the depressurizing tube 58. Therefore, the panel accommodating part 42 of this embodiment is obstruct | occluded in the substantially sealed state which a fluid does not penetrate | invade from the outside.

  Inside the panel housing portion 42 thus sealed, air in the factory containing moisture (humidity) enters during assembly. Also, some moisture may ooze out from the operation board 41 on which the switch 40 and the element are mounted inside the panel housing portion 42. In order to adsorb these existing moisture, the panel accommodating portion 42 has a desiccant placement portion 60 that places a desiccant 59 on the side opposite to the wiring port 51 as shown in FIGS. Is provided.

  The desiccant 59 is disposed in the desiccant disposing unit 60 and adsorbs water floating in the air in the panel housing unit 42 and condensed water. The desiccant 59 is a tablet desiccant (for example, a siblet) in which a porous and amorphous substance is formed, and is formed in a disk shape having a predetermined thickness. The desiccant 59 can physically adsorb moisture, and has a characteristic of releasing the adsorbed moisture when the temperature is increased. Not only the desiccant 59 formed into a disk shape, but also a powder (grain) desiccant and a liquid desiccant packed in a bag may be used. In short, it is sufficient that the desiccant 59 has a capacity that can be adsorbed on the assumption that the moisture content in the air mixed during manufacture and the moisture content exuded from the operation substrate 41 are assumed.

  The desiccant disposing unit 60 includes a pair of recesses that are recessed downward from the bottom 42a of the panel housing unit 42 so as to form a circular shape in plan view. Between the bottom wall 61 of this desiccant arrangement part 60 and the desiccant 59, the heat insulation space (heat insulation part) 64 is provided. Specifically, the desiccant placement portion 60 has a step-like holding portion 63 that protrudes from the bottom wall 61 to the side wall 62 toward the panel housing portion 42 and places the desiccant 59 at a predetermined interval from the bottom wall 61. Is provided. By disposing the desiccant 59 on the holding part 63, a heat insulating space 64 including a gap of a predetermined interval is formed between the bottom wall 61 of the desiccant disposing part 60 and the desiccant 59.

  The bottom 42a of the panel housing portion 42 of the present embodiment is inclined downward from the back side toward the front side. In addition, the bottom wall 61 of the desiccant placement portion 60 is formed to extend horizontally with the lid 17 closed. Moreover, as for the panel accommodating part 42, it is easy to heat up the back side in which valve accommodating part 29A, 29B is located by the flow of high temperature steam, and it is hard to heat up the front side. Therefore, the holding | maintenance part 63 is provided so that the space | interval of the heat insulation space 64 formed may incline toward the front side from the back side so that the back side may be wide and a front side may become narrow.

  In the rice cooker 10 thus configured, the existing moisture that has entered the panel housing portion 42 at the time of manufacture can be adsorbed by the desiccant 59 disposed in the desiccant placement portion 60. Moreover, since the panel accommodating part 42 is sealed and formed so that the convection of the gas to the inside and outside does not arise, it can prevent that the air containing a water | moisture content penetrate | invades from the exterior. Therefore, it can suppress that the desiccant 59 will be in a saturated state and will be in the state which cannot adsorb | suck a water | moisture content. In addition, since the heat insulating space 64 is provided between the bottom wall 61 of the desiccant placement unit 60 and the desiccant 59, the heat of the heat-generating component is transferred to the bottom wall 61 of the desiccant placement unit 60 during operation. It can suppress that the agent 59 is heated up. Therefore, it is possible to suppress the moisture adsorbed by the desiccant 59 from being released again into the panel housing portion 42.

  As a result, it is possible to suppress the liquid crystal panel 39 disposed in the window portion 48 and the panel housing portion 42 from being fogged or adversely affecting all electronic components (elements) mounted on the display substrate. Moreover, since the heat insulating space 64 is formed between the bottom wall 61 of the desiccant arrangement part 60 and the desiccant 59 by providing the holding part 63 protruding from the walls 61 and 62 of the desiccant arrangement part 60, It is possible to suppress the release of moisture from the desiccant 59 while minimizing an increase in manufacturing cost or product cost.
