  Note that the pressing margin L5 size of the surface portion 302 of the operation unit shown in FIG. 4 and the moving pressing margin L4 size of the button 203 of the switch device may be set differently depending on a method not shown.

That is, the sealing packing 62 that closes the door and the box is usually formed of flexible, for example, a soft synthetic resin. Therefore, the height L6 has a certain amount of manufacturing variation. It is well known to those skilled in the art that there is variation in the deflection size due to impact when the door is closed depending on the mass of the door itself and the mass of food stored. Therefore, in order to prevent the door automatic opening device from malfunctioning due to the variation size,
The L2 dimension shown in FIG. 3B needs to be set in advance to a predetermined dimension larger than zero. On the other hand, it is well known to those skilled in the art that, from the viewpoint of usability, the smaller the push allowance L5 dimension of the surface portion 302 of the operation unit shown in FIG. Therefore, for example, it may be configured such that [moving push allowance L4 size of button 203 of switch device]> [push allowance L5 size of surface portion 302 of operation unit].

  Next, a description will be given with reference to FIG.

  5A and 5B are explanatory views for explaining the relative positional relationship between the switch device 200 and the operation unit 300 in the first embodiment of the present invention, where FIG. 5A is a perspective view, and FIG. 5B is a cross-sectional view of the main part of FIG. FIG. The same components as those in FIGS. 1 to 4 described above are denoted by the same reference numerals and detailed description thereof is omitted.

  In the figure, the switch device 200 is configured as a button that slides back and forth in the sliding hole 202c of the case member 202. That is, the switch device 200 can be turned on and off by sliding the button 203 of the switch device back and forth in the sliding hole 202c.

  The waterproof rib 202b has a shape obtained by extending the sliding hole 202c, and the waterproof rib tip 202bb is configured to be flush with the surface portion 203a of the button 203 of the switch device.

  The waterproof rib 202b is configured such that the upper edge portion is thinner than the side edge portion, and the lower end is provided below the lower surface of the sliding hole 202c.

  The concave groove 202d is configured to cover the entire width of the case member 202 on the back side of the waterproof rib 202b.

  Further, the lower portion 203d of the button 203 of the switch device secures a pressing dimension δx that allows the pressing portion 301 of the operating portion to be pressed between the sliding hole opening surface, that is, the flange portion 202a of the case member. It is comprised so that it may do.

  That is, even if the waste of stored food stored in the refrigerator falls or the liquid food spills and adheres to the button surface 203a of the switch device, the food waste or liquid food remains in the δx dimension. It is configured to be easier to fall than the part.

  Further, even if the door position is lowered due to a door load or the like during long-term use, and the pushing portion 301 of the operation portion on the door side is lowered as shown in the dotted line diagram D shown in FIG. Since the push-in dimension δx can be ensured between 202a and 202a, the automatic door opening operation unit 100 is less likely to malfunction.

  Here, a relational dimension between the button 203 of the switch device and the push portion 301 of the operation unit on the door side will be described.

  As shown in FIG. 5A, the height dimension of the button 203 of the switch device is H3, the height dimension of the push portion 301 of the operation part on the door side is H5, and the button 203 and the push portion 301 of the switch device are set. If the relational dimension to H4, H6 is the upper and lower marginal dimension, then “H3 = H4 + H5 + H6”.

  On the other hand, it is well known to those skilled in the art that the door-to-door dimension, for example, the H1 dimension shown in FIG.

  Therefore, it is desirable that the H3 dimension be as small as possible. That is, it is desirable that the H4 and H6 dimensions be as small as possible.

  However, the door position of the refrigerator may be lowered due to the door load during long-term use.

  Therefore, as described above, if it is set in advance so that the pushing dimension δx can be ensured with the flange portion 202a, the automatic door opening device 100 is less likely to malfunction.

  Moreover, as shown in FIG. 4, in the refrigerator, it is necessary to form a packing blocking surface 54a in order to prevent the outflow of cold air.

  However, as described above, when the door position is lowered due to a long-term door load, the packing 62 may hit the waterproof rib 202b, and there is a possibility that a packing gap may occur.

  Therefore, as described above, if the thickness of the upper edge portion of the waterproof rib 202b is made thinner than the side edge portion and the distance between the packing 62 and the waterproof rib 202b is sufficiently secured, the lower position is lowered. In addition, the packing blocking surface 54a is formed, and the risk of cold air flowing out is reduced.

  Further, as shown in FIG. 5A, since the lower end of the waterproof rib 202b is positioned below the lower surface of the sliding hole 202c, water droplets repelled by the waterproof rib 202b travel along the side edge of the waterproof rib 202b. The structure is less likely to enter the sliding hole 202c.

  Further, as shown in FIG. 5B, by providing a concave groove 202d on the back side of the upper edge of the opening of the waterproof rib 202b, water droplets adhering to the partition plate 54 are packed with the packing blocking surface 54a (iron plate) and the case member 202. Even if it enters the case member 202 side from the joint E, the water droplet is guided to the concave groove 202d and is discharged outside from the joint F at the lower end of the case without entering the case. Therefore, even when a water droplet flows into the back side of the prevention rib 202b instead of the waterproof rib 202b side, it is waterproofed by the concave groove 202d and is immersed in the back of the switch device 200 (on the right side in FIG. 5 (b)). The possibility of contact with the contact mechanism 201 is reduced.

  Since it is configured as described above, in the first embodiment of the present invention, the switch device 200 is a button type that slides back and forth in the sliding hole 202c of the case member provided on the side partition side. Since the waterproof ribs 202b are provided at the upper and side edges of the opening 202c of the sliding hole, the stored food residue may drop or the liquid food may spill and adhere to the front surface of the horizontal partition. Even if the button part of the switch device is intruded, the button part of the switch device is guarded by a waterproof rib, so there is little risk of malfunction of the button part of the switch device. A refrigerator with a small amount can be provided.

  Further, the waterproof rib 202b is formed by extending the sliding hole 202c of the case member, the waterproof rib tip 202bb is flush with the button surface 203a of the switch device, and the lower part of the button is the sliding Since the push-in dimension is ensured between the hole opening surface 202a, even if the door position is lowered due to the door load during long-term use, etc., the push part 301 of the operation part on the door side is lowered, Since the push-in dimension δx can be secured between the sliding hole opening surface and the flange portion 202a, it is possible to provide a refrigerator in which the door automatic opening operation unit 100 is less likely to malfunction. Also, even if the waste of stored food stored in the refrigerator drops or liquid food spills and adheres to the button surface 203a of the switch device, the button 203 of the switch device is pressed. In this case, since the food waste or liquid food easily falls from the δx dimension portion, it is possible to provide a refrigerator that is less likely to cause a malfunction of the sliding portion between the button 203 and the case member 202.

  Further, since the waterproof rib 202b has a shape in which the sliding hole 202c of the case member 202 is extended, the waterproof rib 202b and the case member 202 can be integrally manufactured by, for example, injection molding or compression molding using a synthetic resin. Therefore, since a separate part such as the waterproof cap 10 of FIG. 9 described above in the conventional example is not required, a refrigerator that is advantageous in terms of manufacturing cost can be provided.

  In addition, when the door is closed, a gap is provided between the push portion tip 301a of the operation portion and the button 203 of the switch device. Even if the door is pushed with an excessive force when it is closed, the operation of the automatic door opening device is not turned on, so that a refrigerator with few malfunctions can be provided.

  In addition, an operation unit 300 for pushing the button 203 of the switch device for turning on / off the automatic door opening device is provided in the vicinity of the handle handle 61a for opening and closing the door provided on the door side. Since the operation unit can be selectively pushed with at least one finger out of the hands hung, according to the intention of the user of the refrigerator, there is no automatic operation of the automatic door opening device. , A refrigerator can be provided.
