[0015]

Operation of the Embodiment Next, the operation of the installation structure of the evaporation dish in the refrigerator or the like according to the embodiment constructed as described above will be described.

When the evaporating dish 20 is set on the installation member 30, as shown in FIGS. 1 and 2, the evaporating dish 20 is set.
With the rear end part aligned with the setting port 46 of the installation member 30, and the bottom plate 22 placed on the heads 36 of the plurality of screws 35 for fixing the side plates 31, 31 to the base plate 18,
The rear wall 25 is slid rearward until it comes into contact with the rear support plate 43. At this time, since the bottom surface 22a of the bottom plate 22 of the evaporation tray 20 slides only in point contact with the head portion 36 of the screw 35, friction is suppressed and it can be moved backward with an extremely small force. . Also evaporating dish 2
Since the lower surface 22a of 0 is not in close contact with or in contact with the upper surface 18a of the base plate 18 or the upper surface 33a of the mounting portion 33, when the evaporation tray 20 is set, these surfaces 22a,
The inconvenience that scratches and the like are formed on 19a and 33a can be preferably prevented.

Then, as shown by the solid line in FIG. 2, when the rear wall 25 comes into contact with the rear support plate 43, the evaporation tray 20 is pushed up further diagonally while being held in a horizontal posture. Therefore, the rear end of the evaporating dish 20 is pushed above the rear support plate 43, and the locking pin 27 erected on the upper portion of the grip portion 26 is formed at the front end of the horizontal portion 39 of the front support plate 38. Since it is aligned with the notch 41, the rear end is placed on the upper surface of the rear support plate 43, and the front end is set on the installation member 30 while being locked to the front support plate 38 (FIGS. 2 and 5). 3 to 2
(Indicated by the dashed line).

At this time, the high-pressure pipe 19 causes the evaporation tray 2 to
0, and the tip of the drain pipe 17 is located above the rear part of the evaporation tray 20. Therefore, the water generated in the refrigerating chamber 11 is discharged to the inside of the evaporating dish 20 set in the installation member 30 at any time, and the water received in the evaporating dish 20 has a high temperature at the high pressure pipe 19.
Evaporate appropriately by the heat of.

When a large amount of water generated by cleaning the inside of the refrigerating chamber 11 is discharged into the evaporating tray 20 at once, the heat of the high-pressure pipe 19 can be used to efficiently evaporate the water. Since it is impossible, it is necessary to remove the evaporation dish 20 from the installation member 30 and discard the water accumulated inside. Then, when removing the evaporation dish 20 from the installation member 30, first, the evaporation dish 20 is pulled out forward to release the locking between the locking pin 27 and the notch 41 and to be mounted on the rear support plate 43. Cancel the state. Then, the evaporation dish 20
While being kept horizontal, the evaporation tray 20 is placed on the head portion 36 of the screw 35 (shown by the solid line in FIGS. 2 and 3).

The evaporating dish 20 is held while holding the holding portion 26.
By pulling the evaporating dish 20 forward from the setting port 46,
While being slid, it is pulled out of the installation member 30 through the setting port 46. At this time, the evaporating dish 20 has its bottom plate 2
Since the lower surface 22a of No. 2 slides only in a point contact with the head 36 of the screw 35, friction is kept small, and even if a large amount of drainage is received inside and the evaporation tray 20 itself becomes heavy, It can be moved forward with extremely slight force. Further, since the lower surface 22a of the evaporation tray 20 is not in close contact with or in contact with the upper surface 18a of the base plate 18 or the upper surface 33a of the mounting portion 33, when the evaporation tray 20 is taken out, these surfaces 22a, 19a and 33a are scratched. It is possible to preferably prevent the inconvenience of the formation of the like.

[0021]

[Modification] FIG. 5 is a front view schematically showing a modification of the installation structure of the evaporation dish in the refrigerator or the like according to the present invention. In this modified example, a plurality of protrusions 50 protruding above the head 36 of the screw 35 are provided on the upper surface 33a of the mounting portion 33 of each side plate 31, and the protrusion 50 and the evaporation tray 2 are provided.
It is configured so that the bottom surface 22a of the bottom plate 22 at 0 contacts. Also in this configuration, the lower surface 22a of the evaporation dish 20, the upper surface 18a of the base plate 18 and the mounting portion 33 are provided.
Since the upper surface 33a of the evaporation tray 20 is always held in a non-contact state, even if the evaporation tray 20 is slid during the setting work and the removing work, the respective surfaces 22a, 18a and 33a are slid.
It is possible to preferably prevent the inconvenience of scratches and the like being formed. Further, since the lower surface 22a of the evaporating dish 20 is in contact with only the protrusion 50, friction can be suppressed to be small and the evaporating dish 20 can be slid with a very slight force. The protrusion 50 may be formed in an elongated rail shape.

[0022]

As described above, according to the installation structure of the evaporating dish in the refrigerator or the like according to the present invention, the projecting portion is provided on the upper surface of the mounting portion of the side plate of the installing member, and the evaporating dish is set to the installing member. At the time of removal and at the time of removal, the lower surface of the evaporating dish was configured to slide in a state of being in point contact with only the protrusion. Therefore, since the lower surface of the evaporation dish and the upper surface of the mounting portion of the installation member do not come into close contact with each other,
It is preferable to prevent scratches and the like from being formed on the lower surface of the evaporation dish and the upper surface of the mounting portion. Also, since the bottom surface of the evaporating dish does not come into close contact or contact with the upper surface of the mounting part, the friction due to the contact between them can be suppressed to a small level, and even if the evaporating dish becomes heavy due to drainage, it is extremely small. Since it can be slid with various forces, there is an advantage that the work of setting and removing the evaporating dish can be performed easily and smoothly. Further, by using the screw for fixing the side plate to the base plate, it is possible to manufacture at low cost without increasing the number of parts and requiring complicated processing.
