Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is directed to a cooling case machine room that prevents so-called exhaust heat air from returning to the air inlet side of the condenser. It is about structure.

(Prior Art) Generally, in a machine room of a freezing / refrigerating showcase, a condenser of a cooling unit and a blower for exhaust heat are installed in front of and behind the machine room casing, and the periphery of the condenser is surrounded. Peripheral equipment such as electrical box and receiving box for drainage tank is installed in.

In such a showcase, when driving the blower, air for heat exchange is sucked from the front of the machine room, the intake air is heated through the condenser, and becomes exhaust heat air to the rear of the machine room. Exhausted from.

However, since this type of showcase is installed with its rear surface close to the wall surface in the store, the distance between the rear surface of the machine room and the wall surface is narrow, and this exhausted hot air cannot be discharged smoothly. There is. In such a case, the exhaust heat air circulates to the front side of the condenser from the gap between the peripheral side surface of the condenser and peripheral equipment or the gap between the peripheral side surface of the condenser and the machine room casing, and passes through the condenser again. Therefore, there is a problem that the heat exchange efficiency of the condenser is significantly reduced.

In order to avoid such a situation, conventionally, there is known one provided with a metal closing plate that closes a gap between the peripheral side surface of the condenser and the machine room housing and peripheral equipment.

(Problems to be Solved by the Invention) Although this closing plate is formed in conformity with the above-mentioned gap, the outer surface of the peripheral device often has a complicated shape. Has a complicated shape, and a dimensional error easily occurs between the gap and the closing plate.

However, since this closing plate is made of a metal member and does not have elasticity, this closing plate cannot absorb this error, which causes a problem. In addition, since the closing plate is fixed by screws, the number of parts increases, and when installing the closing plate in the machine room where the condenser etc. is already installed, screw holes are provided in the condenser etc. Therefore, the work of attaching the closing plate was troublesome.

In view of the above-mentioned conventional problems, an object of the present invention is to provide a cooling case machine room which is easy to mount and can reliably close a gap.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention installs a condenser of a cooling unit and a blower for exhaust heat in a machine room casing, and surrounds the peripheral side surface of the condenser. In a machine room for a cooling case in which peripheral equipment such as an electrical equipment box and a receiving box for a drainage tank is installed, an elastic closing member is press-fitted in a gap between the peripheral side surface of the condenser and the machine room housing and the peripheral equipment. It is characterized by

(Operation) According to the present invention, since the elastic closing member is press-fitted in the gap between the peripheral side surface of the condenser and the machine room housing and peripheral equipment, the closing member is fixed by the elastic force of the closing member. . Also,
Even if there is some dimensional error between the closing member and the gap, this error is absorbed by the elasticity of the closing member, and
Even if the shape of this gap is complicated, it can be dealt with by this elastic action, and no gap is formed between the closing member and the condenser or the like.

(Embodiment) FIGS. 1 to 3 show an embodiment of the present invention, and FIG. 1 is a perspective view of a cooling case, for example, a refrigerating showcase.

This refrigerating showcase 1 comprises a case body 2 and a machine room casing (hereinafter referred to as a casing) 3 installed vertically, and the inside of the case body 2 is configured as a refrigerating chamber 4, and the inside of the casing 3 is a machine room. It is configured as 5. Further, the side surface of the housing 3 is opened and closed by a machine room cover 7 having an air intake port 6.

FIG. 2 is a front view of the machine room 5 with the machine room cover 7 removed. Inside the housing 3 of the machine room 5, a fin coil type condenser 8 forming a cooling unit and a fan 9 for exhaust heat are installed on the bottom plate 3a. Further, on the upper plate 3b immediately above the condenser 8 in the housing 3, a drainage tank receiving box 10 is hung on the right side, and an electrical equipment box 11 on which electronic components and the like are mounted is hung on the left side. There is. Further, the condenser 8 has a rectangular shape extending in the left-right direction, and has its peripheral side surface, the upper plate 3b of the housing 3 and each side plate 3c, 3d, the peripheral side surface and the receiving box 1.
Member having elasticity between 0 and the electrical equipment box 11,
For example, the first to fourth closing members 1 made of foamed polyethylene
2, 13, 14, and 15 are interposed to prevent air from flowing from the rear side of the condenser 8 to the front side. Each of the closing members 12 to 15 has heat resistance so as not to be thermally deformed at a contact portion of the condenser 8 or the like.

FIG. 3 is a perspective view showing an assembling direction of each of the closing members 12 to 15. The first closing member 12 is interposed in a vertically extending gap A formed between the inner surface of the housing 3 and the right side surfaces of the condenser 8 and the receiving box 10. This first
The closing member 12 is configured to be slightly larger than the gap A, and a part of the closing member 12 is sandwiched between the U vents 8 a before and after the condenser 8 and press-fitted into the gap A. Second closing member 13
Is interposed in a vertically extending gap B formed between the inner surface of the housing 3 and the left side surface of the condenser 8. This second
The closing member 13 is configured to be slightly larger than the gap B, and similar to the first closing member 12, the front and rear U vents 18b.
It is sandwiched between and pressed into the gap B. Further, the third closing member 14 is interposed on the upper surface of the condenser 8 in a vertically extending gap C between the boxes 10 and 11. The third closing member 14 is configured to be slightly larger than the gap C, and is press-fitted into the gap C. Further, the fourth closing member 15 is disposed on the upper surface of the condenser 8 in a gap D formed in a substantially L shape between the housing 3 and the electrical equipment box 11. The fourth closing member 15 is slightly larger than the gap D, and is press-fitted into the gap D. As a result, the inside of the machine chamber 5 is partitioned by the closing members A to D before and after the condenser 8.

According to the present embodiment, the gaps A, B, C, D formed around the peripheral side surface of the condenser 8 are closed by the respective closing members 12 to 15, so that the blower 9 drives the condenser 8 to move. The heat exchange air that has passed from the front to the rear does not flow back to the front side of the condenser 8 through the gaps A to D again.

Further, since each of the closing members 12 to 15 is formed of a foamed polyethylene material having elasticity, its shape,
Even when the size is slightly different from the shape and size of each of the gaps A to D, the error is absorbed by the elastic action, and each of the gaps A to D can be surely closed.

Further, the elastic action of each closing member 12 to 15 causes each gap A.
~ D can be press-fitted, and needless to say, a fastening member such as a screw is not required as in the conventional case, and each device 8, 10, 1
It can be easily installed in the machine room 5 after installation of 1.

(Effects of the Invention) As described above, according to the present invention, the elastic closing member is press-fitted into the gap between the peripheral side surface of the condenser and the machine room housing and peripheral devices. Even if there is some error in the shape and size, this error is absorbed by the elasticity of the closing member, and even if the gap is complicated, the elastic action surely closes this gap. It has the advantage that Further, the elastic action of the closing member has the advantages that it can be securely fixed in this gap, screws and the like are no longer required as in the conventional case, and the work of attaching the closing member is simplified.
