DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly, to a refrigeration cycle unit provided with an air conditioner body, a compressor, a heat exchanger and a refrigerant pipe, and an upper and lower part of the heat exchanger. The present invention relates to an air conditioner provided with upper and lower fixing members fixed to a main body of the conditioner.

2. Description of the Related Art In a heat exchanger, for example, an evaporator as a refrigeration cycle unit of a dehumidifier, an aluminum tube and a large number of aluminum fins (sheets) are used in combination. Many. Therefore, this evaporator is liable to cause fatigue failure due to vibration.

On the other hand, it is difficult for the compressor of the refrigeration cycle unit to avoid the generation of vibration. Therefore, the refrigerant pipe that connects the compressor and the heat exchanger is usually connected to a part of the heat exchanger located nearby and the upper and lower fixing members by binding, etc., so that the vibration generated by the compressor is I was trying to prevent it from being transmitted. However, those using such a binding or the like are not necessarily satisfactory in the anti-vibration effect,
Mounting and mounting operations were also complicated.

SUMMARY OF THE INVENTION The present invention relates to an air conditioner main body, a refrigeration cycle unit having a compressor, a heat exchanger, and a refrigerant pipe, and an upper part and a lower part of the heat exchanger provided in the air conditioner main body. The upper and lower fixing members are fixed to the heat exchanger, and the upper part of the refrigerant pipe is opened between the upper part of the heat exchanger and the refrigerant pipe to interpose an elastic body for vibration isolation. It is elastically pressed and fixed to a member.

That is, according to the present invention, the upper part of the refrigerant pipe is opened between the upper part of the heat exchanger and the refrigerant pipe, and an elastic body for vibration isolation is interposed therebetween. Secure, thereby simplifying fit and preventing vibrations from the compressor from being transmitted to the heat exchanger.

In the present invention, it is preferable that the vibration isolating elastic body has elasticity and permanent low distortion. Specifically, for example, neoprene foamed rubber and silicone rubber are preferable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on an embodiment shown in the drawings. Note that the present invention is not limited to this.

First, in FIGS. 6 and 7, a dehumidifier (1) as an air conditioner has a dehumidifier main body (2), a refrigeration cycle unit (3), and an upper fixing for fixing this unit to the main body (2). Parts (Electrical parts storage parts case) (8)
And a lower fixing member (not shown).

The refrigeration cycle unit (3) includes a compressor (4), a condenser (5) as a heat exchanger, an aluminum evaporator (6), and a heat exchanger and a compressor (4). It mainly comprises a copper refrigerant pipe (7) to be connected.

In FIGS. 1 to 3 together with FIGS. 6 and 7, reference numeral (11) denotes an anti-vibration rubber made of neoprene foam rubber interposed between the upper part of the evaporator (6) and the refrigerant pipe (7). The refrigerant pipe (7) is provided by the elastic force of the elastic body (11).
Is elastically pressed and fixed to the substantially downwardly-facing U-shaped piece (9) of the upper fixing member (8).

Thus, the vibration from the compressor (4) transmitted through the refrigerant pipe (7) is prevented from being transmitted to the evaporator (6), and the fatigue of the evaporator (6) due to the long-term vibration is destroyed. Can be prevented.

Incidentally, a normal heat exchanger is composed of an aluminum fin and a copper tube extending therefrom. On the other hand, heat exchangers made of both aluminum are particularly weaker in fatigue strength of aluminum tubes than copper, and from that point it is necessary to minimize the propagation of vibration to the heat exchanger made entirely of aluminum. The above configuration is preferable.

Next, in FIGS. 4 and 5, the elastic body for vibration isolation (1
1) is first interposed between the refrigerant pipe (7) and the upper part (fin) of the evaporator (6). Then, the upper fixing member (8) is covered from above, and the upper solid member (8) is fixed to the main body (2) with screws (not shown) (screw holes 12). Thus, the refrigerant pipe (7) is elastically pressed by the U-shaped piece (9) of the upper fixing member (8).

[0014]

According to the present invention, the mounting operation can be simplified by opening the upper part of the refrigerant pipe between the upper part of the heat exchanger and the refrigerant pipe and interposing the elastic body for vibration isolation.
With this elastic body, the refrigerant pipe is elastically pressed and fixed to the upper fixing member, and transmission of vibration from the compressor to the heat exchanger can be prevented.
