Description

Vibration-block apparatus for air conditioner

The present invention relates to an air conditioner, and more particularly, to an anti-vibration device for preventing vibration and noise of the components constituting the heat exchange cycle.

Generally, an air conditioner is a device for maintaining indoor air in a state most suitable for use and purpose. For example, in summer it is controlled to cool air condition, in winter the room is controlled to warm heating condition. In addition, the air conditioner controls the humidity in the room, and controls the air in the room to a comfortable clean state.

1 is a cycle diagram illustrating a heat exchange cycle of a general air conditioner. According to this, firstly, a compressor 1 for compressing a working fluid flowing between the components constituting the heat exchange cycle is provided. The compressor 1 receives a low pressure gas working fluid from another element constituting the heat exchange cycle, compresses the working fluid and introduces a high temperature high pressure gas working fluid into the outdoor heat exchanger 3 to be described below. Let's do it.

In the outdoor heat exchanger (3) which has received the working fluid in the high temperature and high pressure gas state from the compressor (1), the working fluid and the air passing through the outdoor heat exchanger (3) are heat-exchanged to exchange the working fluid in the gas state at low temperature and high pressure. To a working fluid in liquid form. In general, the heat removed in the outdoor heat exchanger (3) is equal to the sum of the heat absorbed by the indoor heat exchanger (7) and heat generated in the compression process to be described below.

The working fluid of the low temperature and high pressure liquid state discharged from the outdoor heat exchanger (3) passes through an expansion valve (5) consisting of capillary tubes, and the expansion valve (5) is a low temperature and high pressure liquid state discharged from the outdoor heat exchanger (3). The working fluid of the pressure is reduced to adjust to a state that is easy to evaporate in the indoor heat exchanger (7), and the working fluid flows at a constant rate. The working fluid in the liquid state passing through the expansion valve 5 is ejected in a spray form and turns into gas at the moment when it reaches the indoor heat exchanger 7.

Next, in the indoor heat exchanger (7), a low temperature low pressure gas working fluid flowing through the expansion valve (5) flows in, and heat exchanges with the air passing through the working fluid and the indoor heat exchanger (7). Cool.

2 shows a compressor which is a component of a heat exchange cycle of an air conditioner. As shown therein, the compressor 1 is fastened with a pipe 10 for connecting between the other components constituting the heat exchange cycle of the air conditioner. In general, the pipe 10 is formed of a hollow cylinder-shaped tube, and the working fluid circulating in the inside of the components constituting the heat exchange cycle flows inside the pipe 10.

In the compressor 1, vibration and noise are generated in the process of compressing the working fluid at high pressure. The vibration is transmitted to a pipe 10 connected to the compressor 1, causing the pipe 10 to vibrate and to other components along the pipe 10. In addition, the noise transmitted to the pipe 10 is introduced into the room, which is a space for air conditioning, to be a factor that inhibits the pleasant environment.

As such, in order to prevent vibration generated in the compressor 1, as shown in FIG. 2, the shape of the pipe 10 connected to the front and rear of the compressor 1 may be 'a' or 'b'. 'It is formed as a curved line like a part to prevent vibration by acting as a kind of spring. In addition, the shape of the pipe 10 may be formed in a circular shape around the exterior of the compressor 1 at the upper end or the lower end of the compressor 1 to prevent the transmission of vibration.

In addition, the shape of the pipe 10 of the circular or curved line as described above is damaged when the pipe 10 connected to the compressor 1 or the surrounding parts due to the shaking of the compressor 1 when handling the air conditioner. It also serves to prevent.

In addition, in order to prevent the vibration of the compressor 1 and the vibration of the pipe 10 from resonating and increasing in magnitude, the pipe 10 is equipped with a dustproof hole 12. That is, the vibration isolator 12 is mounted to the pipe 10 to avoid the resonance band of the vibration generated in the pipe 10 and the compressor (1).

However, the dustproof apparatus of the air conditioner according to the prior art as described above has the following problems.

In general, in order to solve the vibration generated in the compressor (1) of the air conditioner, in the prior art, the vibration isolator 12 is mounted on the pipe 10, or some shape of the pipe 10 of a circular or curved line Formed in shape to prevent vibration.

However, as described above, in order to reduce the vibration, a separate part such as the dustproof hole 12 needs to be mounted on the pipe 10, thereby increasing the number of parts and the work process.

In addition, the shape of the pipe 10 formed in a circular shape or a curved line is complicated and difficult to manufacture, and also inconvenient to work, and thus there is a problem in that productivity is low.

In addition, only the overall shape of the pipe 10 may cause vibration of the pipe 10 and the shaking of the compressor 1 when handling the air conditioner. There is a disadvantage in that it is not possible to effectively prevent the surrounding parts from being broken.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to provide a dustproof apparatus for an air conditioner that effectively prevents vibration and noise.

Another object of the present invention is to provide a dustproof apparatus for an air conditioner, which is easy to manufacture and has improved productivity.

It is a further object of the present invention to provide a dustproof device of an air conditioner which prevents breakage of pipes and components during handling.

When the air conditioner is driven, the components constituting the heat exchange cycle operate and heat exchange with the outside air while the working fluid flows through the inside. In this process, the compressor 40 compresses the low pressure working fluid flowing into the compressor 40 from other components to high pressure, and delivers the same to other components. At this time, in the compressor 40, vibration and noise are generated in the process of compressing the low pressure working fluid to high pressure, and the vibration and noise are transferred to the pipe p connected to the compressor 40 to move. .

Vibration and noise transmitted to the pipe (p) is moved to the corrugated pipe 50 along the pipe (p), the dustproof body 52 formed in the corrugated pipe (50) repeats compression and tension in the longitudinal direction To attenuate the noise and vibration, and to prevent the noise and vibration generated by the compressor 40 from being transmitted to other components.

In addition, the shaking of the compressor 40 generated during the handling of the air conditioner is absorbed by the dustproof body 52 whose length of the corrugated shape formed in the corrugated pipe 50 is variable, so that the pipe p and the surrounding parts Since it is not transmitted to the field, it prevents the pipe p or the parts from being damaged.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.

As described in detail above, the present invention has an advantage of effectively preventing vibration and noise by fastening a corrugated pipe having a corrugated shape and varying in length to a component constituting a heat exchange cycle or a pipe connecting the components.

In addition, the overall shape of the pipe can be easily formed by the anti-vibration action of the corrugated pipe, thereby facilitating manufacturing and assembly work, and also improving the productivity.

In addition, since the corrugated pipe absorbs the shaking of the compressor when handling the air conditioner, there is an effect of preventing damage to the pipe or the surrounding components.
