Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a switch mounting device for a cooker that is provided with a switch for controlling energization to the heating element below a support plate that supports the heating element, and the present invention relates to a switch mounting device for a cooker that is provided with a switch for controlling energization to the heating element under a support plate that supports the heating element. This prevents the switch from being damaged and prevents the switch from malfunctioning.

Conventionally, cooking appliances such as rice cookers have a switch 3 on the back side of a support plate 2 that supports a heating element 1, as shown in FIG.
The switch 3 is opened and closed by a lever 6 that penetrates the heating element 1 and the support plate 2 and is linked to the vertical movement of a heat-sensitive device 5 that senses the temperature of the pot 4 placed on the heating element 1 and moves up and down. It was a composition. In this conventional cooking device, when the broth boils over from the pot 4, the broth passes through the through hole of the support plate 2 or is transmitted through the heat-sensitive device 5, and is applied to the lever 6.
The problem was that the contact point of the switch 3 would have a poor contact.

The present invention prevents boiling liquid from splashing on the switch by providing a cover part that covers the switch on the fixing plate that fixes the switch, and forming an upwardly convex bent part on the lever located below the cover part. Embodiments of the present invention will be described below with reference to FIG.

In FIG. 2, 11 is a support plate on which a heating element 12 is mounted and fixed. Reference numeral 13 denotes a heat-sensitive case that is provided through the support plate 11 and the heating element 12. 14 is a heat-sensitive device provided in the heat-sensitive case 13, which is urged upward by a spring 15;
It comes into contact with the pot 16 placed on the heating element 12 and senses the temperature. A negative characteristic thermistor or the like is enclosed in the heat sensitive device 14 to sense temperature. Also, pot 16
However, in some cases, the interlocking fitting 17 is lowered, the lever 23 is pushed down, and the switch 19 is turned on. When the pot 16 is removed, the heat sensitive device 14 moves upwards because it is biased by the spring 15. Therefore, the lever 23 is pulled up using the interlocking metal fitting 17, and the switch 19 is turned off. In this way, this switch mechanism constitutes a pot detection switch that detects the presence or absence of a pot. Reference numeral 18 denotes a switch fixing plate attached to the back surface of the support plate 11, on which the switch 19 is fixed, and a cover part 20 covering the switch 19 is integrally formed. This cover part 20 is inclined toward the heat-sensitive device 14 side, and a through hole 21 is formed in the switch fixing plate near the lower end of this cover part 20. 22 is a through hole formed in the switch fixing plate 18 and located between the support plate 11 and the switch 19. Note that the inner end of the switch fixing plate 18 is in contact with the heat-sensitive case 13,
Positioned. Reference numeral 23 denotes a lever that rotates in conjunction with the vertical movement of the interlocking fitting 17 to open and close the switch 19, and has a bent portion 24 projecting upward in a portion located below the cover portion 20. Reference numeral 25 denotes a draining rib formed on the support plate 11.

In the above configuration, the boiling liquid boiling over from the pot 16 drips through the through hole in the center of the support plate 11, but is caught by the cover 20 and the switch 1
It doesn't take 9. Further, the broth adhering to the cover part 20 is transmitted from the lower end thereof using the through hole 21 as a guide and does not reach the switch 19. Further, even if the broth passes through the heat sensitive device 14 and the interlocking metal fitting 17 and reaches the lever 23, it does not reach the switch 19 due to the bent portion 24.

Note that the switch fixing plate 1 is fixed by the through holes 21 and 22.
The heat transferred to switch 8 is less likely to be transferred to switch 19, and the temperature of switch 19 does not rise much.

As is clear from the above description, according to the cooker switch mounting device of the present invention, a cover portion provided on the switch fixing plate and a bent portion located below the cover portion and projecting upward on the lever are formed. Therefore, even if the broth spills from the pot, it will not reach the switch, preventing the switch from malfunctioning.
