Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator built-in type showcase, and more particularly, to a refrigerator condensing unit which is incorporated in a base of a case body so as to be able to be pulled out forward and an evaporator arranged inside a refrigerator. The present invention relates to a pipe support structure of a refrigerant pipe connecting between the pipes.

[0002]

2. Description of the Related Art An evaporator in which a condensing unit of a refrigerator is mounted inside a base of a case body so as to be able to be pulled out to the front, and the condensing unit is arranged inside the refrigerator as a showcase with a built-in refrigerator. A configuration is known in which a refrigerant pipe connecting between the pipe and the pipe is drawn in a meandering or coiled shape inside the base so as to follow the front drawer of the unit.

FIG. 3 is a front view of such a refrigerator-incorporated showcase (however, a kick plate of a base is removed).
4 to 7 show a configuration of a condensing unit of a refrigerator incorporated in a base of a case and a conventional structure for supporting a refrigerant pipe. In each of the figures, reference numeral 1 denotes a case body of a showcase, 2 denotes a condensing unit of a refrigerator mounted inside a base 1a of the case body 1, and the condensing unit 2 includes a compressor 2a, a condenser 2b, a fan 2c, and the like. The components are assembled on a base plate 2d, and as shown in FIG. 7, are incorporated so as to be drawn out to the front of the case along a guide rail 1b laid on a base 1a.

[0004] A refrigerant pipe 3 connecting between the condensing unit 2 and an evaporator (not shown) disposed inside the refrigerator is routed in a meandering shape on the inner side of the base as shown in FIG. Piping is performed so that the condensing unit 2 expands and contracts in accordance with the forward movement of the condensing unit 2. In addition, the refrigerant pipe 3 is connected to a refrigerant pipe drawn out from an evaporator inside the refrigerator through a pipe joint at a terminal portion 3a rising upward.

Here, in the conventional pipe support structure, the rear end portion (extending in the left-right direction) of the refrigerant pipe 3 is supported while the condensing unit 2 is stored in the base 1a. A support bracket 4 is attached to the rear end of 1a. The supporting bracket 4 has an L-shaped protruding tip portion bent in an inverted V-shape. When the condensing unit 2 is pulled forward from the base 1a, the refrigerant pipe 3 is bent so as to follow the condensing unit 2, and the rear end portion of the condensing unit 2 is detached from the support fitting 4 (see FIG. 7A). When the locking unit 2 is pushed back into the base, the rear end of the pipe is supported over the inverted V-shaped tip of the support fitting 4.

[0006]

However, in the above-described conventional pipe support structure, when the condensing unit is pulled forward from the inside of the base, the following problems are likely to occur in the refrigerant pipe. That is, as shown in FIG. 7, when the condensing unit 2 is pulled forward, the refrigerant pipe 3 drawn and laid in a meandering shape falls down under its own weight when it comes off the support fitting 4, and in particular, the tip portion of a corner bent into a hairpin shape When the condensing unit 2 is pushed into the base or when the condensing unit 2 is pushed into the base, the rear end portion of the refrigerant pipe 3 is caught on the support fitting 4 properly (part P in the figure). There may not be.

[0007] Therefore, in the state as described above,
When the condensing unit 2 is taken in and out of the base,
Each time, the P portion of the refrigerant pipe 3 is rubbed against the floor surface, and furthermore, is sandwiched between the base plate 2d of the condensing unit 2 and the pipe is damaged. An accident such as leakage of the refrigerant may occur.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and is intended for a refrigerator-incorporated type showcase, in which a refrigerant pipe following a refrigerator condensing unit incorporated in a case base is smoothly moved in and out. It is an object of the present invention to provide a piping support structure capable of stably supporting a refrigerant pipe by preventing movement of a refrigerant pipe and damage to the pipe while ensuring movement.

[0009]

According to the present invention, a pipe support member for supporting a refrigerant pipe at a plurality of positions along a pipe path is provided on a base side. The support member is specifically configured in the following form. 1) As a pipe support member, a hook-shaped support for hooking a rear end portion of the refrigerant pipe and locking and supporting the rear end portion is provided.

2) As a pipe support member, a gutter-like support for supporting a pipe portion extending in the front-rear direction of the refrigerant pipe is provided. 3) As a pipe support member, a rail-shaped support member that carries a hairpin-shaped tip portion of the refrigerant pipe and extends in the front-back direction is provided. As described above, along the piping route of the refrigerant pipe routed and piped into the base, by supporting the midway point with a pipe support member, the refrigerant pipe hangs down and is rubbed against the floor surface, It is possible to reliably prevent the pipe from being damaged by being caught between the plates.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In the drawings of the embodiment, the same members in FIGS. 3 to 7 are denoted by the same reference numerals. That is, in the illustrated embodiment, the condensing unit 2 of the refrigerator, which is incorporated in the base 1a of the showcase so as to be able to be pulled out to the front, and the evaporator (not shown) inside the refrigerator are connected to each other. The refrigerant pipe 3 is routed in a meandering manner, and the refrigerant pipe 3
Hook-shaped support members 5 as pipe support members for supporting
A gutter-like support 6 and a rail-like support 7 are installed on the base 1a side.

Here, the hook-shaped support member 5 is fixed to the rear wall of the base 1a, hooks the center of the rear end portion (extending in the left-right direction) of the refrigerant pipe 3, and is suspended and supported at that position. ing. In addition, the gutter-shaped support 6 receives and supports a part of the portion that extends back and forth from the rear end of the refrigerant pipe 3 toward the pipe end 3a. Further, the rail-shaped support 7
Is a convex channel body laid in the front-rear direction on the bottom wall of the base 1a, on which a tip (P portion in the figure) of a bent portion in a hairpin shape of the refrigerant pipe 3 is carried.

[0013]

As described above, according to the structure of the present invention,
When pulling out and pushing in the condensing unit of the refrigerator from the base of the showcase and pushing in it, while ensuring the smooth movement of the refrigerant pipe that expands and contracts following the condensing unit, the refrigerant pipe droops due to its own weight.
In addition, it is possible to prevent damage to the piping pipe due to this, and to improve reliability.
