Description

  The present invention relates to a cooking device, and more particularly to a cooking device that cools an electrical component that generates heat during operation.

  In the past, “a heating cooker that sucks air into the housing from the front of the housing to cool electric components that generate heat” has been proposed (for example, see JP-A-2006-176619).

Japanese Patent Laid-Open No. 2006-176619

  However, if an air inlet is provided in the front of the housing, not only the design may be impaired, but also the user may be uncomfortable due to the generation of an air flow.

  The subject of this invention is providing the cooking device which can reduce a possibility of giving a user discomfort without impairing the designability.

  The cooker according to the present invention includes a casing, an operation panel, an electrical component, and a blower. The housing has an opening / closing door on the upper front side and a first side wall including an opening. An opening is formed in the opening. The operation panel is disposed below the opening / closing door. The electrical component is disposed on the back side of the operation panel. Note that the “electric part” mentioned here includes an electronic part. This electrical component is housed inside the housing. The blower is disposed between the opening and the electrical component. The blower sucks air outside the housing (hereinafter referred to as “outside air”) from the opening formed in the opening and blows it to the electrical component.

  As described above, in this cooker, an opening, that is, a suction port is provided on the side wall. For this reason, this cooker increases the degree of freedom of design creation. Moreover, it is rare that the user of a cooking appliance stands on the side wall side when using the cooking appliance. Therefore, this cooker can reduce a possibility of giving a person discomfort without impairing the design.

  In addition, it is preferable that this cooking device is further provided with a liquid container. The liquid container is disposed between the second side wall and the electrical component. Here, the second side wall is a side wall opposite to the first side wall. The blower blows air from the electrical component toward the liquid container.

  In this cooker, the blower blows air not only to the electrical components but also to the liquid container. For this reason, in this cooker, not only an electrical component but a liquid container can be cooled with one blower.

  Moreover, it is preferable that this cooking device further includes a heating unit. The heating unit is disposed on the bottom side of the space on the back side of the electrical component so as to be substantially parallel to the electrical component.

  For this reason, in this cooking device, it is easy to dispose the heating unit away from the electrical component. Therefore, in this cooker, it is possible to reduce the influence of heat generated from the heating unit on the electrical components.

And the cylindrical hole of this protrusion part 173B is connected to the 2nd through-hole of 2nd base | substrate part 173A. And this protrusion part 173B penetrates into the baking chamber RB of the oven toaster 100 through the left side wall 111b of the main body wall 111 as shown in FIG. That is, the cylindrical hole and the second through hole function as a supply port SP that supplies water vapor generated in the small boiler 170 to the firing chamber RB. Note that, as shown in FIG. 6, a roof plate RF is provided directly below the protrusion 173 </ b> B on the firing chamber side. The roof plate RF is for preventing water droplets formed by condensing water vapor supplied from the small boiler 170 from entering the guide groove GD. As shown in FIG. It extends obliquely downward from the inner surface of the wall 111b. Further, as shown in FIG. 6, a baffle plate JP is disposed in front of the protrusion 173B on the firing chamber side. This is provided for the purpose of distributing water vapor uniformly to the firing chamber RB.

  As shown in FIG. 5, the one wing portion 173C extends from the lower portion of the left edge of the second base portion 173A toward the left side. The one wing portion 173C has a function of attaching the small boiler 170 to the left side wall 111b of the main body wall 111 and holding the safety device SA.

  The second fastening portion 173D is similar to the first fastening portion 171D in the upper left corner, upper right corner, lower right corner, lower left corner, upper edge center, right edge center, lower edge center, and left edge center of the second base portion 173A. It is provided outside the eight locations and faces each first fastening portion 171D. An opening is formed in the second fastening portion 173D. When the second block body 173 is fastened to the first block body 171, the position of the opening coincides with the position of the opening of the first fastening portion 171D of the first block body 171. In this state, the bolt BT is passed through the opening, and the nut is screwed into the leg portion of the bolt BT from the back side of the second block body 173, whereby the first block body 171 and the second block body 173 are connected. It will be concluded. At this time, since the first block body 171 and the second block body 173 are fastened through the packing PK, there is no water leakage to the outside.

  As shown in FIGS. 5 and 6, the head portion 173E is formed on the upper right side of the second base portion 173A, and fixes the thermistor 177.

(8-3) Packing The packing PK is a rounded rectangular frame-shaped object, and is formed from an elastomer or a rubber material. The packing PK is used to form an airtight structure between the first block body 171 and the second block body 173, as shown in FIG.
