Description

[Detailed description of the invention] This invention relates to a switch mounting device that is installed in response to the opening and closing of the outer lid of a rice cooker, and its purpose is to provide a rice cooker that has a simple structure and is easy to assemble. The present invention aims to provide a switch mounting device for a device.

An embodiment of the present invention will be described below with reference to the drawings. 1 is a substantially cylindrical outer case, 2 is an inner case disposed within the outer case 1 via a heat insulating wall 3, 4 is a pot detachably disposed within the inner case 2, and 5 is an outer case. An outer lid that opens and closes the top of 1.
One end of a handle 6 fixed to the upper surface of the outer lid 5 is rotatably supported by the outer case 1 via a hinge 7, and the other end of the handle 6 has a claw portion 8 at its lower end.
A clamp 8 with a is rotatably supported. Reference numeral 9 denotes a switch cover made of synthetic resin that is fixed to the outer case 1 with screws in correspondence with the clamp 8, and has an engaging portion 10 at its upper end that is engaged with a claw portion 8a; A rectangular hole 11 is provided in the lower part of the engaging part 10. 12 is an actuator inserted into the rectangular hole 11 so as to be horizontally movable; 13
is an operating lever whose lower end is rotatably supported by a pivot support 14 that is integrally formed and protrudes from the back side of the switch cover 9, and whose upper end is in contact with the back side of the actuator 12. Reference numerals 15 and 15 designate a pair of holding claws that are integrally molded and protrude from the back side of the switch cover 9, and are located on both left and right sides of the approximate center of the operating lever 13.
Claw portions 15b, 15b are formed at the tips of each of a, 15a. And side surfaces 15c, 15c on the opposite side of side surfaces 15a, 15a of each holding claw 15, 15.
are provided with reinforcing protrusions 15d, 15d.
Reference numerals 16, 16 and 17, 17 are positioning ribs located at the upper and lower parts of the holding claw 15 and protruding from the switch cover 9, and these ribs are located on the left and right sides of the operating lever 13, respectively. 18 is the holding claw 15, 15
This is a micro switch attached to the back side of the switch cover 9 while being held by one side 18a of the switch cover 9.
are brought into contact with the positioning ribs 16, 16 and 17, 17, respectively, and the claw portion 15 of the holding claw 15 is brought into contact with the other side surface 18b.
b and 15b are engaged with each other, and an actuating protrusion 19 protruding from one side 18a is brought into contact with an intermediate portion of the actuating lever 13. And the holding claws 15, 15
The spacing is set to be approximately equal to the horizontal width of this micro switch 18, and therefore the side surface 15
a, 15a are in contact with the left and right side surfaces of the micro switch 18. Reference numeral 20 denotes a positioning rib protruding from the switch cover 9 so as to receive the lower surface of the micro switch 18. Reference numeral 21 denotes a rectangular opening provided in the outer case 1 so as to correspond to the micro switch 18. A part of the micro switch 18 and the tip of the holding claw 15 enter the heat insulating wall 3 through this opening 21. are doing. And each holding claw 15
The reinforcing ridges 15d, 15d are in contact with the left and right inner edges of the opening 21. Reference numeral 22 denotes a rice cooking switch knob that protrudes outward from an opening provided in the lower part of the switch cover 9, and is used to heat the pot 4 via the rice cooking switch and micro switch 18 operated by this knob 22 in series. A heater (not shown) is energized.

Now, in the above embodiment, when the outer lid 5 is closed, the claw part 8a of the clamp 8 engages with the engaging part 10, and when the actuator 12 is pushed inward by the claw part 8a, the actuating lever 13 is moved. The micro switch 18 is turned on by rotating in the direction of arrow A and pushing in the operating protrusion 19. Therefore, if the rice cooking switch is turned on by pressing down the knob 22 in this state, the heater for heating the pot 4 is energized. However, when the outer lid 5 is not completely closed, the actuator 12 protrudes outward and the micro switch 18 is turned off. Electricity is not applied to the heater that heats the rice 4, thus preventing cooking failure such as rice being incompletely cooked due to rice being cooked without the outer lid 5 being completely closed.

According to this embodiment configured in this way, when attaching the micro switch 18 to the switch cover 9, the micro switch 18 is attached to the holding claws 15, 15.
When pushed between them, the holding claws 15, 15 expand to the left and right due to their own elastic force, and pushing the micro switch 18 until it abuts one side 18a against the positioning ribs 16, 17 holds it. Due to the elastic force of the claws 15, 15, the claw parts 15b, 15b
is engaged with the micro switch 18 to be in a predetermined installed state, and this micro switch 1
8, there is no need for screws or mounting hardware, etc., and the retaining claw 15, positioning rib 1
6, 17, and 20 are all integrally molded from synthetic resin on the back side of the switch cover 9, and there is no need for adjustment work for positioning the micro switch 18. Overall, the number of parts is small and the configuration is simple. It is simple and can be assembled extremely easily. Further, the reinforcing protrusion 15d of the holding claw 15 is connected to the opening 2 of the outer case 1.
1, so even if the temperature of the holding claws 15, 15 increases due to the heat transmitted from the pot 4 through the heat insulating wall 3 during rice cooking and the holding force decreases, the holding claws 15, 15 This ensures that the micro switch 18 is prevented from expanding laterally, and therefore no problem such as the micro switch 18 falling off from the switch cover 9 occurs.

As is clear from the embodiments described above, the present invention can provide a rice cooker switch mounting device that has a simple structure and can be easily assembled.
