Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a refrigerator having a cover that shields the outlet of the evaporating dish and the front legs.

[0002]

[Prior Art]

 4 and 5 are views showing a conventional refrigerator disclosed in, for example, Japanese Utility Model Laid-Open No. 63-175791, in which 1 is an outer case of a refrigerator made of steel plate, 2 is an opening edge of the outer case 1. Flanges formed by folding back inside 3, front girders whose both ends are fixed to the flange 2 of the outer box 1, and numerals 4 and 5 are formed inside by folding the edge of the opening of the front girder 3 forming the outlet 7 of the evaporating dish 6. They are the upper flange and the lower flange. Reference numeral 8 denotes a bottom plate fixed on the upper surface of the upper flange 4, and the evaporation dish 6 is housed under the bottom plate 8. Reference numeral 9 is an evaporating dish heat radiation pipe attached to the lower surface of the evaporating dish 6, 10 is a front leg fixed to the lowermost part of the outer box 1, 11 is a door for covering the front of the refrigerator, 12 is fixed to the door 11, and the outer box is magnetized by magnetic force. A gasket that closely adheres to the flange 2 and the front girder 3 of 1 and a cover 13 that shields the outlet 7 of the evaporating dish 6 and the front leg 10 are detachably attached to the front girder 3. Reference numeral 14 denotes a heat radiation pipe that extends from the side surface of the outer box 1 to the front part of the bottom plate 8 and is in close contact with the outer box 1. Reference numeral 15 is a heat conductive tape such as an aluminum tape having good heat conductivity, and the heat radiating pipe 14 is fixed to the bottom plate 8.

Next, the operation will be described. Since the outlet 7 of the evaporation tray 6 is covered by the cover 13, the convection of air under the bottom plate 8 is bad. The defrosting water collected in the evaporating dish 6 becomes steam by the heat of the evaporating dish radiating pipe 9. When this water vapor comes into contact with the comparatively cooled bottom plate 8 due to heat conduction from the inside of the refrigerator, especially when the convection of air is bad, a dew condensation phenomenon occurs on the lower surface of the bottom plate 8 and the bottom plate 8 or the front girder 3 Rust is generated on the edge of the bottom plate or dew attached to the bottom plate 8 drops onto the floor surface, but the heat of the heat radiating pipe 14 crawling on the bottom plate 8 is transferred to the bottom plate 8 and the front by the heat conductive tape 15. Since it is effectively transmitted to the third digit, etc., it is difficult to get dew on it. A cover 13 was attached to the front girder 3 and the flange 2 of the outer case 1 so as to close the sound generated from a compressor (not shown) installed in the lower rear part of the bottom plate 8.

[0004]

[Problems to be solved by the device]

 Since the conventional refrigerator is configured as described above, it is necessary to extend the heat radiating pipe 14 that extends along the side surface of the outer box to the front portion of the bottom plate so that the bottom surface of the bottom plate or the like does not condense. As the bending process of the heat radiating pipe increases, the work of attaching the heat conductive tape 15 is performed, so the workability is poor, and the heat of the heat radiating pipe may be changed depending on how the heat conductive tape is attached. However, there was a problem that the dew drops on the bottom surface of the bottom plate and rust occurs on the bottom plate and the edge part of the front girder, and the dew drops on the floor surface.

The present invention has been made to solve the above problems, and can reduce the bending process of the heat radiating pipe and the attaching work of the heat conductive tape, and the bottom surface of the bottom plate due to the work variation. The purpose of the present invention is to obtain a refrigerator that can prevent rust from forming on the bottom plate and the edge of the front girder due to dew condensation on the floor, and dew drop on the floor surface.

[0006]

[Means for Solving the Problems]

 In the refrigerator according to the present invention, a ventilation wall is provided on the shielding wall that shields the outlet of the evaporating dish and the outlet of the cover that shields the front legs, and the door that covers the front of the refrigerator is at least lowered to a position that shields this ventilation opening. It is a postponement.

[0007]

[Action]

 In the refrigerator according to this invention, the ventilation holes in the cover's shielding wall improve the convection of air in the lower part of the refrigerator's bottom plate, which is the upper part of the evaporation dish. As a result, the vent hole is hidden and does not spoil the appearance.

[0008]

【Example】

 Example 1. An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numerals 1 to 13 in the drawings correspond to those of the conventional example described with reference to FIGS. 4 and 5, and detailed description thereof will be omitted. Reference numeral 16 is a shield wall provided on the upper edge of the cover 13, and shields the outlet 7 of the evaporation dish 6. Reference numeral 17 denotes a plurality of vents provided in the shield wall 16 which communicate with the outlet 7. The lower end of the door 11 is shielded from the front of the shield wall 16 from the front of the shield wall 16 at least from the front. It extends down to the position. Reference numeral 18 is a claw portion that is appropriately provided on the left and right inside the shielding wall 16 and is locked to the upper flange 4 and the lower flange 5 of the front girder 3.

Next, the operation of the above embodiment will be described. Since the outlet 7 of the evaporation dish 6 is covered with the shielding wall 16 having the ventilation hole 17, the convection of air at the lower part of the bottom plate 8 which is the upper part of the evaporation dish 6 is improved. Therefore, the defrosting water collected in the evaporation dish 6 becomes steam due to the heat of the evaporation dish heat radiation pipe 9. Even if the water vapor comes into contact with the bottom plate 8 that is relatively cooled by heat conduction from the inside of the refrigerator, the convection of air is good, and therefore it is difficult for the water vapor to be condensed on the lower surface of the bottom plate 8. For this reason, there is no need to transfer the heat of the heat radiating pipe 14 to the bottom plate 8 as in the conventional case, and the conventional heat radiating pipe 14 crawling on the bottom plate 8 and the heat conductive tape 15 to which it is attached are unnecessary. . Further, the ventilation port 17 is hidden by the door 11 so as not to be seen. Since the cover 13 is in close contact with the front girder 3 and the flange 2 of the outer case 1 by the claw portion 18 and the like, the sound of the compressor (not shown) is less likely to leak from the gap and is pushed up from below. It does not come off. In this case, the cover 13 and the evaporation tray 6 are attached and detached while the door 11 is fully pulled out.

According to this embodiment, since the lower end of the door 11 is extended downward so as to shield the front of the outlet 7 of the evaporation tray 6 which is shielded by the cover 13, it can be seen from the front of the refrigerator or the like. As a result, the door 11 is wide, so that the inside of the refrigerator feels large, and the cover 13 looks small, which has the effect of improving the design of the refrigerator.

Example 2. In the first embodiment described above, the claw portion 18 of the shielding wall 16 is locked to the upper flange 4 and the lower flange 5 of the front girder 3, but as shown in FIG. The rung 5 may be provided with a convex portion 19 having an approximately V-shaped cross section formed toward the inside, and the convex portion 19 may be fitted into a hole portion 21 provided in a fitting piece 20 formed in the shielding wall 16. The same effect as that of the above embodiment is obtained.

In the first and second embodiments, the cover 13 is provided with the ventilation hole 17 to improve the air flow in the lower portion of the bottom plate 8 and the heat radiation pipe 14 need not be crawled. The pipe 14 is made to crawl on the bottom plate 8 in the same manner as in the conventional case, and the cover 13 is provided with the same shape as that of the above-mentioned first and second embodiments except that the vent hole 17 is eliminated, and the door 11 is provided with the above-mentioned first and second embodiments. Similarly to the above, it may be configured to extend downward so as to shield the front of the outlet 7. In this case, although there is a problem that dew may adhere to the bottom plate 8 etc. as in the conventional case, As in the first and second embodiments, the door 11 is widened, the cover 13 looks small, and the refrigerator design can be improved.

[0013]

[Effect of the device]

 As described above, according to the present invention, the ventilation wall is provided in the shielding wall that shields the outlet of the evaporating dish and the outlet of the cover that shields the front legs, and the door is lowered at least to a position that shields this ventilation opening. Since it was extended to the structure, the convection of the air under the bottom plate of the refrigerator was improved, and there was no need to transfer the heat of the heat dissipation pipe to the bottom plate. This eliminates the need for the heat dissipation pipe that was crawling on the bottom plate and the heat conductive tape that was affixed to it, as well as the bending process for the heat dissipation pipe that was crawling on the bottom plate and the work of attaching the heat conductive tape. In addition, since the ventilation port is hidden by the door, it is possible to obtain an inexpensive one without deteriorating the design and to reliably prevent the generation of dew, so that the dew falls on the bottom surface appropriately. In addition, there is an effect that a bottom plate and a front girder without rusting can be obtained.
