Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a rice cooker in which electrical components such as control components are housed in the inner bottom of the exterior body.

(Prior art) Generally, in a rice cooker, when a storage case is provided at the inner bottom of the exterior body and control parts etc. are stored in this storage case, the inside of the storage case is heated by the rice cooking heater located at the inner bottom of the outer pot. As a result, the temperature rises to extremely high temperatures and there is a risk of failure of control parts, etc. Conventionally, various heat shielding structures have been adopted between the rice cooker and the storage case, but none of them are structurally efficient. It is complicated and is not very desirable from the viewpoint of ease of assembly.

(Purpose) This proposal was made in view of the above points, and aims to provide a structure that is structurally simple and can exhibit sufficient heat shielding effects.

(Example) An example of the present invention shown in the drawings will be described in detail below.

1 is an exterior body consisting of a cylindrical outer body 2 and a bottom cover 3 connected to the lower end thereof; 4 is a rectangular opening provided on the side surface of the outer body 2; and 5 is a body that fits into the opening 4 from the outside. This is a display panel that mainly houses display elements, switches, and other electrical components. Reference numeral 6 denotes a storage case disposed at the inner bottom of the exterior body 1, in which a printed circuit board 7 including electronic control parts, a transformer 8, etc. is housed. Reference numeral 9 denotes a heat shielding cover attached to the outer surface of the storage case 6 with a small gap, and reference numeral 10 denotes an outer pot housed inside the exterior body 1, in which an inner pot 11 is housed so as to be freely accessible. A heating plate 12 is attached to the inner bottom of the outer pot 10 with a plurality of screws 13, and a rice cooking heater 14 is embedded therein.

Reference numeral 15 denotes a heat shield plate having a substantially semicircular shape, and has a plurality of cut and raised pieces 16 formed on its outer periphery, and a mounting piece is attached to the tip of one cut and raised piece 16 that is particularly inward. 17 is bent and formed. This mounting piece 17 is attached to the outer pot 10 together with the switch mounting bracket 18 using one of the screws 13 for attaching the hot plate 12, and the heat shield plate 15 is attached to the tip of each cut and raised piece 16. outside pot 1
Contact with the outer bottom surface of 0. 19 is the exterior body 1 and the outer pot 1
By inserting a part of the heat insulating material between the heat insulating cover 9 of the storage case 6 and the heat insulating plate 15, the heat insulating plate 15 is pushed up, and the cut and raised piece 16 is placed outside the outer pot 10. Hold it in contact with the bottom. Therefore, although the heat shield plate 15 is attached with one screw 13,
By using the heat insulating material 19, it can be installed in a stable state, and workability during assembly is also significantly improved. Reference numeral 20 denotes a thermo cover that is disposed at the center of the inner bottom of the outer pot 10 and attached to the outer pot 10 by claw pieces 21, and one of the claw pieces 21 is inserted into the through hole 2 of the heat shield plate 15.
By inserting and bending the heat shield plate 15 through the screws 13, rotation of the heat shield plate 15 about the screws 13 is prevented.

In the above configuration, the heat shield plate 15 is connected to the rice cooking heater 1
The heat shield plate 15 has the effect of blocking radiant heat from the bottom of the outer pot 10 heated by 4, and since the heat shield plate 15 is in surface contact with the outer pot 10 only at the mounting piece 17, and the other parts are in line contact, The conductive heat from the pot 10 is also suppressed to a small level, and since the heat insulating material 19 and the heat shield cover 9 are present between the heat shield plate 15 and the storage case 6, the temperature rise inside the storage case 6 is suppressed to a low level. Therefore, there will be no failure of control parts etc. due to heat.

In the above embodiment, if the dimensions of the cut and raised pieces 16 are made different and the heat shield plate 15 is tilted inward and slightly downward, the water falling from the hole in the outer pot 10 onto the heat shield plate 15 can be prevented. can be guided to a location away from the storage case 6 for treatment, and favorable results can be obtained in terms of waterproofing measures.

(Effects) As described above, according to the configuration of the present invention, by using the heat insulating material, the number of fixing points using screws etc. of the heat shield plate can be reduced, the structure can be simplified, and assembly workability can be improved. The plate and heat insulating material suppress the temperature rise inside the storage case and reliably protect electrical components from heat, making this an extremely useful idea in practical terms.
