The present invention relates to a clothes treating apparatus, and more particularly, to a hot air supply device and a clothes treating apparatus which can reduce operating noise of a clothes treating apparatus.

Recently, various types of clothes processing apparatuses have been used together with washing machines for washing clothes.

 For example, drum-type dryers for drying clothes after washing, cabinet-type dryers for hanging clothes and drying, and refreshers for supplying hot air to clothes and refreshing clothes have been developed. In this case, the term refresh refers to a process of removing wrinkles or removing odors from clothes by applying heat and steam to used clothes.

On the other hand, among the clothes treating apparatus, a refresher or a dryer supplies hot air to clothes by heating air mainly using a heater. Such heaters include a gas heater that burns gas to heat air, and an electric heater that heats air by electric resistance. In recent years, electric heaters, which are easy to install and have a simple structure, have been used.

By the way, when the air is heated by the electric heater as described above, the high temperature heat of the heater can be directly transmitted to the clothes, there is a problem that the clothes may be damaged, or even a fire inside the clothes processing apparatus.

In addition, since the electric heater heats the air by using electricity, in order to heat the air to a desired temperature, a large amount of electricity is consumed, and thus a lot of maintenance costs are involved.

Recently, a heat pump using an evaporator, a compressor, a condenser, and an expansion valve in which a refrigerant circulates, and a clothes treating apparatus for generating hot air through a blower have been developed, and the range of use thereof is gradually increasing.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the hot air supply apparatus and clothes processing apparatus according to an embodiment of the present invention.

In describing the present embodiment, the names and signs of the elements that are defined are defined in consideration of the functions in the present embodiment, it should not be understood as a meaning limiting the technical components of the present embodiment.

Hereinafter, in order to explain the hot air supply device and the clothes processing apparatus according to the present invention, a cabinet dryer having a drying space of the cabinet for convenience, will be described as an embodiment. However, the present invention is not limited thereto, and of course, the present invention may be applied to various home appliances and industrial devices using a hot air supply device.

First, the garment treatment apparatus according to the present invention will be described with reference to FIGS.

Although the present invention describes a refresher for supplying hot air to clothes as a clothes treating apparatus to refresh clothes, the present invention is not limited thereto, and other clothes processing that may be equipped with a hot air supply device using a hip pump described below. The idea of the present invention can also be applied to an apparatus.

Referring to FIG. 2, the clothing processing apparatus 100 according to the present invention includes a cabinet 110 in which an accommodation space 112 for accommodating clothes 10 is formed, and air for supplying hot air to the accommodation space 112. It is provided with a hot air supply (150, see FIG. 3) for heating and dehumidifying, a steam generator (130, see FIG. 3) for selectively spraying steam to the receiving space (112).

The cabinet 110 is provided with various components described below, and an accommodation space 112 is formed therein to receive clothing. The accommodation space 112 is selectively isolated from the outside by the door 116. In addition, the receiving space 112 is provided with a variety of support 114, etc. to hang the clothing 10, the configuration for supporting such clothing 10 is well known in the field to which the present invention belongs, detailed description thereof will be omitted. do.

On the other hand, inside the cabinet 110 is formed a machine room 120 is accommodated in the hot air supply unit 150 and the steam generator 130 for selectively supplying hot air and steam to the receiving space (112). Machine room 120 is preferably located below the receiving space 112, the above-described hot air supply device 150 and the steam generator 130 is located therein. As such, the reason why the machine room 120 is located at the lower part is that the hot air and steam supplied to the accommodation space 112 have a property to rise, and thus, the machine room 120 is located at the bottom to direct hot air and steam toward the upper part. It is because supplying is preferable.

Hereinafter, the steam generator 130 and the hot air supply device 150 will be described with reference to FIG. 3.

 In FIG. 3, only components of the steam generator 130 and the hot air supply device 150 are illustrated for convenience of description, and it is not shown that the piping lines connecting the components are not shown.

The steam generator 130 may supply steam to the accommodation space 112 (see FIG. 1) in which the clothes 10 are accommodated to remove wrinkles and the like that may occur on the clothes, and further, the effect of sterilization by high temperature steam. In addition, it is for exerting a refreshing effect due to swelling of clothing cloth.

The steam generator 130 is provided with a heater (not shown) for heating the water therein, thereby generating steam by heating the water and supplying the steam to the receiving space 112. An external faucet or the like may be used as the water supply source for supplying water to the steam generator 130, or a container type water supply source provided on one side of the machine room 120 may be used.

 This container type water supply is preferably detachably installed, so that the user can separate the water supply from the machine room 120 to fill the water and reinstall it.

In addition, the steam generated by the steam generator 130 is supplied to the accommodation space 112 through the steam hose 132 and the steam nozzle 134. In this case, the shorter the length of the steam hose 132 is preferable in order to prevent the temperature of the steam is lowered or the steam is condensed while the steam moves along the steam hose 132. Therefore, when the machine room 120 is located below the accommodating space 112, the steam nozzle 134 preferably supplies steam through the upper part of the machine room 120, that is, the lower part of the accommodating space 112. .

In addition, the back of the machine room 120 may be provided with a circulation fan 140. The circulation fan 140 supplies the air outside the machine room 120 into the machine room 120, so that the hot air supply device 150 and the steam generator 130 are driven to increase the temperature inside the machine room 120 excessively. To prevent it.

As such, the timing of spraying steam by the steam generator 130 may be appropriately modified. Preferably, steam is sprayed before the hot wind is supplied by the hot wind supply device 150. This is because it is preferable to supply hot air and then to dry the clothes after injecting high temperature steam.

Meanwhile, as illustrated in FIGS. 3 to 4, the hot air supply device 150 is positioned inside the machine room 120 to heat and dehumidify air to supply hot air to the accommodation space 112. The hot air supply device 150 is located on one side of the steam generator 130 for supplying steam.

Hot air supply device 150 of the present invention is provided with a heat pump using the evaporator 154, the compressor 151, the condenser 152 and the expansion valve 153 through which the refrigerant is circulated, thereby dehumidifying the air and heating Done. That is, the evaporator 154 absorbs latent heat of ambient air while the refrigerant evaporates, thereby cooling the air to condense moisture in the air and dehumidifying the air. In this case, although not shown in the drawings, it is preferable to have a storage source for collecting the condensed water condensed. That is, the condensed water condensed in the evaporator 154 is collected in the storage unit under the evaporator 154, and the condensed water collected in the storage unit is supplied to the storage source by a pump or the like and stored.

 In addition, when the refrigerant is condensed in the condenser 152 via the compressor 151, the latent heat is released toward the surrounding air to heat the surrounding air. Accordingly, the evaporator 154 and the condenser 152 function as a heat exchanger, and the air introduced into the machine room 120 is dehumidified and heated through the evaporator 154 and the condenser 152 to the receiving space 112. Supplied.

As such, the air heated by the hot air supply device 150 using the heat pump may have a somewhat lower temperature than the air heated using a conventional heater, but may dehumidify the air without using a separate dehumidifier. do.

Therefore, the air supplied back to the receiving space 112 by the hot air supply device 150 corresponds to a relatively 'low temperature dry air' (here, 'low temperature' does not mean that the temperature is absolutely low, but heating But it is used in the sense that the temperature is relatively low compared to conventional heating air).

That is, the air supplied by the hot air supply device 150 of the present invention has a lower temperature than the hot air of the conventional clothing treatment apparatus, but supplies the dehumidified air without a separate dehumidification device, thereby easily drying the clothes. It becomes possible to refresh.

Specifically, the air inlet 122 through which the air in the receiving space 112 is introduced into the inside of the machine room 120 is communicated to the upper end of the machine room 120, the air inlet 122 and the evaporator 154, A duct 156 connecting the condenser 152 and the fan 155 forms a flow path through which air flows. Air introduced into the machine room 120 through the air inlet 122 by the duct 156 is dehumidified and heated while passing through the evaporator 154 and the condenser 152 and is again received by the fan 155 by the receiving space 112. Supplied by.

Here, although not shown in the figure, the air inlet 122 may be preferably provided with a filter. By providing a filter at the air inlet 122, it is possible to filter various foreign substances that may be included in the air flowing into the machine room 120 from the receiving space 112 and to supply only fresh air to the receiving space 112.

On the other hand, the pressure pulsation noise caused by the operation of the compressor 151 and the movement of the fluid is generated during the operation of the hot air supply device 150 as described above. In order to reduce the pressure pulsation noise, a pulsation noise unit 160 is further provided between the compressor 151 and the condenser.

As shown in FIG. 5, the pulsation silencer 160 includes a first silencer 162 that attenuates a specific frequency band and a second silencer 164 that attenuates a frequency band different from that of the first silencer 162. . Here, the first silencer 162 and the second silencer 164 have the same structure as the same conventional expandable silencer. However, the shape of the first and second silencers 162 and 164 is not limited, and a reflective or suction silencer may be used.

On the other hand, the first silencer 162 (or the second silencer 164) is formed in an expanded state than the second silencer 164 (or the first silencer 162). This is because the noise attenuation efficiency and the attenuated frequency band change according to the effective volume when the effective volume of the silencer is changed.

Meanwhile, in the present invention, in order to change the effective volumes of the first silencer 162 and the second silencer 164, the cross-sectional areas of the silencers 162 and 164 are maintained and the length is changed. This is because the length of the silencer has a large influence on the frequency band in which it is attenuated.

That is, the diameter D1 of the first silencer 162 and the diameter D2 of the second silencer 164 are formed the same, and the first silencer 162 has the second silencer 164 rather than the length L1. The length L2 of is formed relatively long. Accordingly, the frequency band of the noise attenuated by the first silencer 162 and the second silencer 164 is formed differently.

 On the other hand, the noise attenuation characteristics in the pulsation noise control unit 160 represents a graph characteristic as shown in FIG. That is, the pressure pulsation noise generated in the compressor 151 is attenuated while passing through the first silencer 162 and exhibits the same attenuation characteristics as M1, and the noise passing through the first silencer 162 passes through the second silencer 164. It is attenuated while exhibiting the same attenuation characteristics as M2.

Accordingly, the pressure pulsation noise passing through the pulsation silencer 160 including the first and second silencers 162 and 164 is the same as T1 due to the attenuation characteristics and interference of the first and second silencers 162 and 164. It has attenuation characteristics and is attenuated.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, The present invention may be modified in various ways. Therefore, modifications of the embodiments of the present invention will not depart from the scope of the present invention.

For example, the hot air supply apparatus and the clothes processing apparatus according to the present invention may be implemented by adding and replacing components and processes having other additional functions. However, all other modified embodiments include the essential elements of the present invention should be considered to be included in the technical scope of the present invention.
