Incidentally, the conventional mounting structure for the kick plate 9 has the following problems. That is,
(1) When the kick plate 9 is attached to the base 7 of the main body case, the engagement hole 9b opened at the lower edge of the kick plate 9 is hidden behind the plate and cannot be seen from the front. Since it is a long and heavy object, there is a difficulty in operability that it is difficult to fit the engagement hole 9b into the engagement claw 10a of the support washer 10.
[0006]
(2) When the kick plate 9 is removed in the direction of arrow I in FIG. 5A when the kick plate 9 is removed, the edge of the engagement hole 9b of the kick plate 9 that is caught by the engagement claw 10a of the support washer 10 A large twisting load is applied. In this case, the support washer 10 is thick and strong, whereas the kick plate 9 is made of a thin steel plate and has low strength. Therefore, the peripheral portion of the engagement hole 9a of the kick plate 9 is weak. Is easily deformed, and this causes a problem that the entire kick plate is warped. In particular, if the kick plate 9 is tilted forward without being removed from the support washer 10 and placed on the floor surface, the kick plate 10 is greatly deformed around the engaging hole.
[0007]
The present invention has been made in view of the above points, and its purpose is to fix the kick plate so that the above-mentioned problems can be solved, the kick plate can be inserted and removed easily, and high reliability can be secured in terms of strength. An object is to provide a refrigerator-incorporated showcase having an improved structure.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, an air cooling type condensing unit of a refrigerator is accommodated in a machine room defined inside the base of the case body, and the cooling air is passed through the opening end surface of the cooling unit. In the showcase with built-in cold air, in which a sheet metal kick plate with a mouth is detachably attached,
A latch that bends in the shape of a "<" from the lower edge of the kick plate and protrudes downward is provided in a distributed manner on the left and right sides, and a support washer that supports the kick plate is provided on the base side, and the support washer opens. The latch is inserted into the engaged hole to support the kick plate (Claim 1). Specifically, the latch is configured in the following manner.
[0009]
(1) The latch is welded to the kick plate (Claim 2).
(2) The latch is integrally formed with the kick plate (Claim 3).
[0010]
According to the above configuration, the latch of the kick plate protrudes downward so that it can be seen from the front of the plate. Therefore, when the kick plate is mounted on the base, the position of the latch is visually checked while the kick plate is attached to the support washer on the other side. It can be easily inserted by aligning the position with the open engagement hole. Moreover, when the kick plate is attached and detached, even if the kick plate is tilted forward while the latch is engaged with the engagement hole of the support washer, the latch itself is bent into a “<” shape, so that the support washer It is possible to avoid deformation and warping of the kick plate without applying an unreasonable twisting load between the engagement holes. Thereby, it is also possible to place the latch on the floor surface as it is hooked in the engagement hole of the support washer without dropping the kick plate and moving it forward of the base.
[0011]
In addition, the effect of ensuring high strength can be obtained by welding and joining the latch to the kick plate as a separate part, and the number of parts can be reduced by forming the latch integrally with the kick plate.
