本考案は家庭用冷蔵庫等に取付けられている庫
内灯及び冷気強制対流用フアンモータ等のドア開
閉に連動して開閉するいわゆるドアスイツチに関
する。[Detailed Description of the Invention] Industrial Application Field The present invention relates to a so-called door switch that opens and closes in conjunction with the opening and closing of the door of an interior light, a cold air forced convection fan motor, etc. installed in a household refrigerator or the like.
従来の技術

る。Conventional technology Generally, this type of switch is buried in the insulating wall inside the refrigerator in order to prevent an explosion caused by an arc at the switch when the door is opened or closed in the event of a gas leak in the kitchen, etc. It is. On the other hand, in order to save energy, the heat insulating material for refrigerators is generally made of polyurethane foam, which has a high heat insulating property, and is filled in the inner and outer casings and the doors thereof by integral foaming.

側に取付けている。 That is, as shown in FIG. 1, in a conventional general refrigerator, a foam insulation material 2 is filled between an outer box 1a and an inner box 1b of a refrigerator main body 1, and a door 3 filled with the foam insulation material 2 is opened in the direction of the arrow. When the refrigerator body 1 is opened and closed, a push button 4a of a door switch 4 provided in the foamed heat insulating material 2 of the refrigerator body 1 is pressed to open and close the door switch. The door switch 4 is attached to the heat insulating material side of the inner box 1b.

ける場合、適正寸法の確保が困難になる。 Therefore, when integrally foaming the foamed heat insulating material 2, if the door switch 4 is attached to the inner box 1b first, the foaming jig outer frame 23 and the foaming jig core 24 will be separated as shown in FIG. In order to store the box combined with the outer box 1a and the inner box 1b, the door switch 4 is
In order to release the protrusion of the push button 4a, a foam jig core 23 is used.
In this case, when the foamed heat insulating material 2 is filled between the outer box 1a and the inner box 1b, the foaming pressure will cause the recess 25 to escape from this part.
Since the inner box 1b facing the inner box 1b cannot be directly received by the foaming jig core 24, it may deform and the finish may deteriorate, or when attaching a shelf member (not shown), etc. to the inner box 1b, ensure proper dimensions. becomes difficult.

Therefore, in order to secure the mounting recess 5, it is necessary to provide a switch cover 5a that can withstand the foaming pressure of the insulation material in the inner box 1b, and to introduce the switch connection lead wire l into the inner box 1b. There is. Further, when inserting the door switch 4, it is necessary to scrape out the lead wire l from inside the switch cover 5a and connect it, and then insert the door switch 4 while re-inserting the lead wire l inside the switch cover 5a.

b. The foam insulation material 2 is attached from the inner box 1b side of the outer box 1a. And door switch 6 is 2
A push button 8 is housed in one of the divided main body cases 7. This push button 8 is moved up and down by the elastic force of a spring 10 along a sliding guide rib 9 provided inside the main body case. Further, inside the main body case 7, a spring plate 11 having first and second inclined surfaces 11a and 11b is fitted into a mounting rib 12 provided inside the main body case 7, and near the tip of the spring plate 11. A locking portion 13 such as a small protrusion projecting from the main body case 7 is provided on the main body case 7.

様のアクシヨンとなる。 On the other hand, the push button 8 is provided with a small protrusion 14 on the surface facing the spring plate 11 and a large protrusion 15 above this. When the push button 8 is pushed in against the spring 10, the spring plate 11,
The first and second inclined surfaces 11a and 11b are successively bent outward by a small protrusion 14 and a large protrusion 15. That is, FIGS. 3 to 6 sequentially schematically illustrate the operation relationship between the push button 8 and the spring plate 11. FIG. 3 shows a state in which the push button 8 has begun to be pushed in the direction of the arrow from the position shown in FIG. Next, FIG. 4 shows a state in which the small protrusion 14 of the push button 8 is further pushed in while sliding on the first inclined surface 11a of the spring plate 11. Next, FIG. 6 shows the state when the push button 8 is pushed in until the head of the push button 8 is flush with the outer surface of the main body case 7, and at this time, the small protrusion 14 of the push button 8 touches the tip of the spring plate 11. On the other hand, the spring plate 11 attempts to return to the state shown in FIG.
At this time, the small protrusion 14 of the push button 8, which is trying to return upward by the spring 10, is locked to the tip of the spring plate 11, and is maintained in the state shown in FIG. 5. Furthermore, the large protrusion 15 at this time is the second part of the spring plate 11.
It is only in contact with the inclined surface 11b. When the push button 8 is pushed in further from the state shown in FIG. As shown in FIG. 6, the spring plate 11 rides over the small protrusion 13 provided on the main body case 7 while slightly deforming it, thereby releasing the lock of the small protrusion 14 of the push button 8 by the spring plate 11. On the contrary, the spring plate 11 then hits the locking part 13 from the main body case 7 and is locked so that it does not return as shown in FIG. becomes the action of

兼ねる固定接片板19と20間を開閉せしめる。 In addition, a normal contact opening/closing mechanism as a door switch will be explained. The push button 8 is provided with a pressing portion 8a that rotationally drives a cam 17 inserted into a pin 16 protruding from the case body, and as the push button 8 moves up and down, the cam 17 is rotated clockwise and counterclockwise. The holding position of the sliding piece of the cam 17 cut and raised from the plate 18 is moved to open and close the space between the fixed contact pieces plates 19 and 20, which also serve as the fulcrum member of the contact plate 18.

せる。 The switch formed as described above is brought into a locked state by pushing the push button 8 almost flush with the outer surface of the main body case 7, that is, the state shown in FIG. 5, and then connecting the lead wire l to the fixed contact plates 19 and 20. Inner box 1
The inner box 1b and the outer box 1a are assembled by inserting the inner box 1b into the mounting hole 22 of the inner box 1b and covering it with a flexible sheet 21 such as soft urethane foam to prevent the foamed heat insulating material 2 from leaking.

る。 Then, the box body assembled with the inner box 1b and the outer box 1b is stored between the foaming jig outer frame 23 and the foaming jig core 26 shown in FIG. 8, and a foamed heat insulating material is filled between the inner and outer boxes. In this case, since the push button 8 of the door switch 6 is housed in the switch body as shown in FIG. There is no need for the recess 25 which serves as an escape, and therefore the foamed heat insulating material 2 can be filled without deformation of the inner box 1b due to the foaming pressure. After filling the insulation material, the refrigerator body 1 is removed from the foaming jig, and the door switch 6 is unlocked by simply pushing the push button 8 further into the switch body surface as shown in FIG. The normal functioning state is restored as shown in FIG.

Moreover, in this case, there is no need to provide a recess in the core jig for the push button, and deformation of the inner box due to foaming pressure is prevented. And since the door switch can be attached to the inner box in advance, the lead wires can be connected in advance, simplifying the process.

る。 In addition, the switch cover to prevent insulation material leakage as shown in the conventional example is no longer necessary, and instead only a flexible material such as soft urethane foam needs to be pasted. can be reduced and insulation properties can be improved. Furthermore, as in the conventional case, after foaming the insulation material, pull out the lead wires from inside the switch cover, connect them, and then insert the switch into the switch cover while placing the lead wires in the switch cover again, which greatly reduces the difficult work of wiring. be done.
