Abstract

PURPOSE:To preclude the upward warpage of the bottom surface of a member for evaporating water produced by defrosting by a method wherein the evaporating member is provided with an auxiliary elastic supporting member at the central part of the upper surface of the same. CONSTITUTION:Eaves type fixing units for fixing both sides of an member 14 for evaporating water produced by defrosting, which is made of a resin, in the direction of the height of the member 14 are provided at both sides of a heating member 11, including a square flat heat transfer plate 12 having a heat source of a high- temperature refrigerant pipe 13. An auxiliary elastic supporting member 16, having a height substantially equal to a gap between the lower surface of a projection 23 fir a refrigerator main body 15 in the fore-and-aft direction, is formed at the central part of the upper surface of member 14 for evaporating water produced by defrosting. Accordingly, when the member 14 for evaporating water produced by defrosting is put on the heating member 11, the auxiliary supporting member 16 is abutted against the projection 23 of the refrigerator main body 15 whereby the warpage of the evaporating member 14, which is readily produced upon heating the evaporating member 14 by the heating member 11 and upon forming the evaporating member 14, can be precluded and the heat transfer plate 11 can be contacted closely with the evaporating member 14.

[0010]

Since the refrigerator according to the present invention is constructed as described above, it has the following effects. According to the first aspect, when the defrosting water evaporating member is placed on the heating member, the auxiliary support portion abuts on the protrusion of the refrigerator body. It is possible to prevent warping of the defrosting water evaporating member that tends to occur during molding of the frosting water evaporating member, and to bring the heat transfer plate and the defrosting water evaporating member into close contact with each other. In addition, due to the close contact, chattering noise is less likely to be generated from the defrosting water evaporation member and the heat transfer plate due to the influence of the vibration of the compressor. According to the second aspect, since the locking claw portion is locked in the locking hole, the defrosted water is likely to be generated when the defrosted water evaporation member is heated by the heating member and when the defrosted water evaporation member is molded. It is possible to prevent the evaporation member from warping and to bring the heat transfer plate and the defrost water evaporation member into close contact with each other. In addition, due to the close contact, chattering noise is less likely to be generated from the defrosting water evaporation member and the heat transfer plate due to the influence of the vibration of the compressor.
