  A spring receiving portion 43c is provided on the lower surface of the lever 43, and the lever 43 and the operation key 42 are pushed upward in response to the repulsion of the spring 45 provided in the operation case 39.

  In order to prevent the lever 43 from being released upward, the operation case 39 is provided with a stopper 39c provided with a claw that is restrained from the upper left and right sides behind the wall 39a.

Next, the structure of the operation key 42 and the lever 43 will be described with reference to FIGS. 7, 8, and 9.
7A is a top perspective view of the operation key 42 in the direction of arrow E in FIG. 5, and FIG. 7B is a bottom perspective view of the same. The front and rear side surfaces of the operation key 42 are provided with a recess 42 c that is cut out to prevent contact with the lever 43. A flat surface 42a is provided on the lower side of the operation key 42, and a circular arc-shaped key arc portion 42b extending in the depth direction is provided at a substantially central portion of the flat surface 42a. Further, a claw portion 42d is provided for preventing the operation key 42 from falling off, and the claw portion 42d is provided at a distance that does not hinder the movable amount of the lever 43 described later, and is inserted into a hole (not shown) of the operation case 39. .

  8A is a top perspective view of the lever 43 in the direction of arrow E in FIG. 5, and FIG. 8B is a bottom perspective view thereof. On the upper side of the lever 43, there are provided narrow and narrow flat surfaces 43d on the left and right sides, and arc-shaped and disk-shaped lever arc portions 43e extending in the depth direction are provided at substantially both ends in the short direction of the plane 43d. The lever arcuate portions 43e are arranged in pairs on the left and right sides at intervals.

  In the state where the operation key 42 is assembled on the upper side of the lever 43 as shown in FIG. 9, the key arc portion 42 b provided on the operation key 42 abuts on the plane 43 d provided on the upper side of the lever 43.

  Further, the lever arcuate portion 43 e provided in the lever 43 abuts on a flat surface 42 a provided on the lower side of the operation key 42.

  The key arc portion 42b is positioned between the pair of lever arc portions 43e, and guides the key arc portion 42b of the operation key 42 from dropping off from the flat surface 43d of the lever 43.

The present embodiment has the above configuration, and the operation will be described next.
When turning on / off the power of the main body 2 that is dropped from the upper surface of the kitchen cabinet 1, it is arranged at the right end of the upper surface operation unit 9 on the front side in the operation unit 35 provided on the front side of the plate 3, An operation button 19 provided on the operation sheet 36 is pressed. When the operation button 19 is pressed, the waterproof sheet 37 covering the operation unit set 38 is pressed through an operation hole provided in the sheet sticking surface 34a of the operation unit plate 34. The waterproof sheet 37 depresses the upper side of the operation key 42 against the force pushing the operation key 42 upward by the spring 45.

  The range in which the operation key 42 can be moved in the front-rear and left-right directions is restricted by walls 39 a that surround the left and right and front-rear corners of the operation case 39.

  Then, the key arc portion 42b provided on the lower plane 42a of the operation key 42 comes into contact with the upper plane 43d of the lever 43.

  At the same time, the lever arcuate portion 43e provided on the upper plane 42a of the lever 43 abuts on the lower plane 42a of the operation key 42. Further, the left and right sides of the key arc portion 42b are sandwiched between the pair of lever arc portions 43e, and the movement in the left-right direction is particularly restricted, and the movement is mainly possible only in the front-rear direction.

  FIG. 9A shows a state before the operation button 19 is pressed, and FIG. 9B shows a state after the operation button 19 is pressed. In FIG. 9A, the spring 45 is not substantially compressed before the operation button 19 is pressed. The plane 42a of the operation key 42 and the plane 43d of the lever 43 are substantially horizontal and substantially parallel.

  Next, as shown in FIG. 9B, the spring 45 is compressed after the operation button 19 is pressed. When the lever 43 is pressed by the operation key 42, the switch pressing portion 43 b side is lowered downward with the fulcrum portion 43 a of the lever 43 as a fulcrum. As a result, the flat surface 43d of the lever 43 is inclined with the fulcrum 43a side being high and the switch pushing portion 43b side being low.

  Then, the switch pressing portion 43b of the lever 43 presses the operating point 44a of the switch 44, and the commercial power source is energized to the main body 2.

  When the operation button 19 is pressed, the plane 42a of the operation key 42 is substantially horizontal and does not become parallel to the plane 43d of the lever 43. At this time, the recess 42 c of the operation key 42 functions to avoid the inclination of the flat surface 43 d of the lever 43.

  In FIG. 9A, the outer periphery of the key arc portion 42b of the operation key 42 and the flat surface 43d of the lever 43 abut each other at a point, and at the same time, the outer periphery of the lever arc portion 43e of the lever 43 and the flat surface 42a of the operation key 42 Are in contact by dots.

  When the operation button 19 is pressed, the outer periphery of the key arc portion 42b of the operation key 42 contacts and slides on the flat surface 43d of the lever 43 as shown in FIG. 9B. The outer periphery of the lever arc 43e of the lever 43 also slides in contact with the flat surface 42a of the operation key 42 at a point.

  Then, the lever 43 pivots downward to the switch pushing portion 43b with the fulcrum portion 43a as a fulcrum, and turns on and off the operating point 44a of the switch 44.

  As described above, when the operation button 19 moves up and down, the outer periphery of the key arc portion 42b of the operation key 42 and the flat surface 43d of the lever 43 are always brought into contact with each other at a point, and the outer periphery of the lever arc portion 43e of the lever 43 is By always abutting and sliding on the flat surface 42a of the operation key 42 at a point, the operation key 42 always operates with a low contact resistance. Therefore, when the operation button 19 is pressed with a finger, there is no variation in the strength of the operation force even at the center or corner of the operation button 19.

  As described above, according to the present embodiment, it is possible to provide a good power switch without being limited to the size of the provided switch and without impairing the operability.
