Description

Multiple muffler and air-conditioning apparatus including the same {Multiple muffler and air-conditioning apparatus including it}

As the standard of living improves, many people use refrigeration and air conditioning products such as refrigerators, air conditioners and kimchi refrigerators. These refrigeration and air conditioning products basically maintain the temperature using a refrigeration cycle. 1 is a schematic view for explaining a refrigeration cycle.

As shown in FIG. 1, refrigeration and air conditioning products include a compressor 1, a condenser 2, a capillary tube 3, and an evaporator 4, which are connected by a pipe 5 through which refrigerant flows. It is.

When a current is applied to the compressor 1 to operate the compressor 1, the compressor 1 compresses the refrigerant introduced at a low temperature and low pressure to a high temperature and high pressure and discharges it to the condenser 2, and the condenser 2 is a compressor 1. The heat of the high temperature and high pressure refrigerant introduced from the heat is discharged to the surroundings so as to be the medium temperature and high pressure state.

The refrigerant passing through the condenser 2 expands into a cold refrigerant having a low temperature and low pressure saturated state while passing through the capillary tube 3.

The coolant thus absorbs heat from the surroundings while passing through the evaporator (4). At this time, the air around the evaporator (4) from which the heat is taken out is discharged to the room to cool the room and at the same time to take heat away from the surrounding air. The refrigerant generated is vaporized and introduced to the compressor 1 in a gaseous state to be recycled.

Refrigeration and air-conditioning products that operate according to these operating principles are generally used indoors, and therefore, consumers are quite sensitive to the energy efficiency of the product as well as the level of noise generated from the refrigeration and air-conditioning products.

In the refrigeration and air-conditioning products, the most noise generated is the suction and discharge pipes of the compressor related to the compression of the refrigerant. In the related art, a noise blocker (also called a muffler or silencer) is considered in consideration of the noise band generated from the suction and discharge pipes of the compressor. Designed and equipped to reduce noise.

Recently, however, a number of products equipped with inverters and linear compressors for high efficiency have been released. Since the products equipped with such compressors use a variable speed rather than the existing constant speed type, the compressors of such refrigeration and air conditioning products have a plurality of products. The operation is performed in the operation mode, and thus the noise generated in the suction and discharge pipes also has a plurality of frequencies.

Conventionally, since a compressor of a refrigeration air conditioner is operated at a constant speed, only a noise in a single frequency range is generated, and a noise suppressor is used to reduce the noise. Recently, however, a number of products equipped with inverters and linear compressors have been released. Since the products equipped with such compressors use a variable operating speed rather than the existing constant speed type, the compressors of these refrigeration and air conditioning products are operated in a plurality of operation modes. Therefore, since a plurality of noises having different frequencies are generated, it is difficult to effectively reduce noises having such a plurality of frequencies only with the conventional noise blocker.

The present invention has been invented to solve the above-described problems, the present invention includes a multiple noise blocker combined with a plurality of noise suppressors having different diameters and sizes in order to effectively reduce a plurality of noises having different frequencies and the same. The purpose is to provide a refrigeration and air conditioning products.

According to another preferred feature of the invention, a plurality of noise suppressors are provided continuously.

According to another preferred feature of the present invention, a pipe is installed between the plurality of noise suppressors so that the plurality of noise suppressors are discontinuously installed.

According to another preferred feature of the invention, the plurality of noise suppressors are sequentially installed in order of diameter from one side.

According to another preferred feature of the present invention, the above-described multiple noise suppressor is installed in at least one of the suction pipe and the discharge pipe of the compressor.

Multiple noise suppressors according to the present invention can effectively reduce noise having different frequencies. In particular, there is an effect that can significantly reduce the noise of refrigeration and air-conditioning products such as refrigerators, air conditioners, kimchi refrigerators used in homes equipped with inverters and linear compressors.

Hereinafter, the configuration and operation of an embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the following examples are provided to enable those skilled in the art to fully understand the present invention, but the scope of the present invention is not limited by the embodiments described below.

2 is a schematic diagram of a multiple noise suppressor as an embodiment according to the present invention. As shown in FIG. 2, the multiple noise suppressor according to the present invention has a form in which a plurality of noise suppressors are coupled to each other. Here, the plurality of noise suppressors are designed to have different lengths and diameters to reduce noises having different frequencies. Since the length and diameter of the individual noise suppressors are designed by a known method according to the frequency of the noise to be reduced, the description of the determination of the length and diameter of the noise suppressors is omitted here.

For example, in the present embodiment, the multi-noise silencer 10 is formed by combining three noise-breakers 12, 13, and 14. The first noise suppressor 12 has a diameter of D11 and a length of L11, the second noise suppressor 13 has a diameter of D12 and a length of L12, and the third noise suppressor 14 has a diameter of D13 and a length of L13. Therefore, the multiple noise canceller 10 in the present embodiment can effectively reduce noises having three different frequencies. Reference numeral 11 is a pipe connected to the multiple noise suppressor.

The number of noise suppressors installed here is determined by the number of frequencies of noise to be reduced.

In addition, in the multiple noise suppressor 10, individual noise suppressors may be installed in sequence from one side in diameter order. Arranged in order of diameter means that the diameter may be arranged in order of increasing diameter, or may be arranged in order of decreasing diameter.

3 is a schematic diagram of a multiple noise suppressor as another embodiment of the present invention. As shown in FIG. 3, the two silencers 22 and 23 having different diameters and lengths are not continuously arranged as shown in FIG. 2, but the pipe 21 is disposed between the two silencers 22 and 23. It has a structure connected by.

Such a multiple noise suppressor may be used in a portion where a plurality of noises having different frequencies occur. There is no particular limitation on the use of the multiple noise suppressor according to the present invention, but may be used in the case of using a refrigeration air conditioner such as a refrigerator, an air conditioner, a kimchi refrigerator, especially an inverter or a linear compressor used in a home.

Figure 4 is a schematic diagram for explaining the refrigeration cycle used in the refrigeration air-conditioning product including a pipe equipped with a multiple noise suppressor according to the present invention.

As shown in FIG. 4, the multiple noise suppressor 10 may be used in the suction pipe and the discharge pipe of the compressor 1 which generates the most noise in the refrigeration air conditioning product. It is also possible to install only one of the suction pipes and the discharge pipes of the compressor 1.
