TECHNICAL FIELD

The present invention relates to a compressor noise suppressing structure for suppressing noise generated during compressor operation and a dehumidifier having the same, and more particularly, to a compressor noise suppressing structure in which a compressor is simultaneously covered by a housing and a component, the component being formed to extend from a different component so as to be integrated therewith, and a dehumidifier having the same.

BACKGROUND ART

A mechanism or device using a refrigerating cycle such as a refrigerator, a dehumidifier, or the like, uses a compressor as an internal component. The refrigerating cycle includes a compressor compressing a heat exchange refrigerant to have high temperature and high pressure, a condenser releasing heat from the refrigerant compressed to have high temperature and high pressure in the compressor, a capillary tube lowering pressure of the refrigerant having pressure increased by the condenser, and an evaporator evaporating the refrigerant which has passed through the capillary tube to lower a temperature thereof. Here, when the compressor compresses a refrigerant as a heat exchange material to have a high temperature high pressure state, a large amount of noise and heat are generated.

In the related art, a circumference of the compressor is covered by a sound absorbing material component to reduce noise generated when the compressor operates, but in this case, there is a difficulty in dissipating heat generated by the compressor.

In particular, when heat dissipation is hindered, a temperature of the compressor increases which increases a load of the compressor, resulting in an increase in vibrations of the compressor. Thus, simply covering the circumference of the compressor with the sound absorbing material component causes a large amount of noise due to poor heat dissipation, and thus, the effect of reducing noise by installing an acoustic absorbent may be insufficient.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the shapes and dimensions of elements may be exaggerated for clarity.

First, a compressor described according to an embodiment of the present invention may be used in a refrigerator, a dehumidifier, or the like, using a refrigerating cycle, and in the present disclosure, a compressor noise suppressing structure100provided in a dehumidifier200will be described as an example. However, the compressor noise suppressing structure100is not limited to the dehumidifier200and may be employed in any device as long as the device is required to suppress noise generated by a compressor.

As illustrated inFIG. 1, the compressor noise suppressing structure100according to an embodiment of the present invention may include an installation member120and a noise-proof member110.

The installation member120may support and accommodate components installed within the housing230and fixed to a base frame130. The base frame130may coupled to the bottom of the housing230to accommodate the compressor noise suppressing structure100together with the housing230to form an outer appearance of the apparatus. The installation member120may be fixed to an upper portion of the base frame130.

Also, the installation member120may have a mounting surface121formed on an upper surface thereof to allow components to be installed or supported thereon within the housing230. As illustrated inFIG. 9, the dehumidifier200according to an embodiment of the present invention may include a condenser214, a capillary tube213, and an evaporator212, besides a compressor211constituting a refrigerating cycle within the housing230. Also, in order to expel dehumidified air, the dehumidifier200may include a component such as a blowing unit220having a scroll casing, a fan, a motor, or the like. Thus, the installation member120may be configured to have the mounting surface121provided on upper surface thereof to accommodate or support at least some of the foregoing components.

Also, the installation member120may have installation space125formed therein to accommodate a component. In the case of the dehumidifier200according to an embodiment of the present invention, a water storage tank240accommodating water condensed by the condenser214may be provided in the installation space125. The water storage tank240may be installed to be positioned on the underneath of the condenser214, and to this end, the water storage tank240may be accommodated in the space125formed within the installation member120.

The noise-proof member110may extend from the installation member120to cover at least one side of the compressor211. The compressor211may have a structure installed on the base frame130, so the noise-proof member110is not required to cover a lower side of the compressor211. Thus, in the present disclosure, it is assumed that covering at least one side of the compressor211by the noise-proof member110means that the noise-proof member110is installed to cover at least a portion of five sides (a front side, a rear side, left and right sides, and an upper side), excluding the lower side among the six sides of the compressor211.

The noise-proof member110may be integrally formed with the installation member120supporting or accommodating components installed within the housing230, thus providing a soundproof effect and simplifying the assembly process.

Meanwhile, as illustrated inFIG. 2(b), the upper region of the base frame130is divided into a region Z1in where the compressor211is installed and a region Z2positioned opposite to the compressor211. The installation member120may have a partition122installed between the region Z1with compressor and the region Z2opposite to the compressor211in order to block noise generated by the compressor211from being transmitted to the other region Z2.

Namely, in order to block noise from the compressor211, the partition122may be installed in a portion from which the noise-proof member110starts to extend.

In this manner, the partition122installed on the installation member120has a structure covering one side (the right side) of the circumference of the compressor211, and the noise-proof member110covers at least a portion of the other remaining four sides (the front side, the rear side, the left side, and the upper side) excluding the lower side and the right side of the circumference of the compressor211.

Meanwhile, the configuration in which the noise-proof member110covers the entire sides (i.e., the six sides including the lower side covered by the base frame130and the right side covered by the partition122) of the compressor211together with the frame130and/or the partition122may be desirable in terms of noise blocking at an initial stage of driving the compressor211.

Namely, covering the entire sides of the compressor211with the noise-proof member110may be advantageous in terms of noise blocking at the initial stage of driving the compressor211, but in this case, after the compressor211is driven for a predetermined period of time, heat generated by the compressor211cannot be effectively emitted, increasing a temperature of the compressor211. The increased temperature of the compressor211increases a load of the compressor to increase vibrations of the compressor211. Namely, the defective heat dissipation causes additional noise, which is disadvantageous in terms of noise blocking.

Thus, in an embodiment of the present invention, preferably, the noise-proof member110extends from the installation member120to cover the compressor211such that at least one side of the compressor211is opened.

Also, since the compressor211has a connection pipe250connected to the condenser214, the evaporator212, and the capillary tube213constituting a refrigerating cycle, if the circumference of the compressor211is entirely covered, it will be difficult to install the connection pipe250, or the like. Thus, preferably, the noise-proof member110may be configured to cover the compressor211such that at least one of the sides of the compressor211is opened.

For example, as illustrated inFIGS. 2 and 3, the noise-proof member110may include a first extending member111extending from a first surface123as one side of a wall portion of the installation member120toward the compressor211to cover one side of the compressor211and an upper extending member112extending from an upper surface of the installation member120, i.e., from the mounting surface121, toward the compressor211to cover at least one portion of the upper surface of the compressor211. In this case, the bottom of the compressor211is coupled to the base frame130and the right side thereof is surrounded by the partition122, the noise-proof member110is configured to allow the two sides (the left side and the front side) of the compressor211to be opened. As illustrated inFIGS. 2 and 3, the partition122of the installation member120serves as one side (the right side) of the noise-proof member110covering the compressor211.

Also, as illustrated inFIG. 4, the noise-proof member110may further include a bent member113bent from an end portion of the first extending member111to cover the compressor211, in addition to the first extending member111and the upper extending member112. The bent member113may cover the entirety of one side of the compressor211, or as shown inFIG. 4, the bent member113may be formed to be bent forwardly from the first extending member111to cover a portion of one side of the compressor211.

Meanwhile, in the configuration ofFIG. 4, the partition122of the installation member120serves as one side (the right side) of the noise-proof member110covering the compressor211. In this case, the compressor211is configured such that one side (the front side) thereof among the entire sides thereof is open, having a more effective structure than the structure having two opened sides (the left side and the front side inFIG. 3) in terms of noise-proofing effect, and heat of the compressor211can be smoothly dissipated through the opened first side.

As illustrated inFIG. 5, in another embodiment of the present invention, the noise-proof member110may include the first extending member111extending from one side of the first surface123, a second extending member114extending from the other side (Please see124inFIG. 2(b)) of the first surface123, and the foregoing upper extending member112. Here, the second extending member114extends toward the compressor211from the installation member120on the side opposing the first extending member111to cover one side (the front side) of the compressor211. In the case of the configuration ofFIG. 5, the partition122of the installation member120serves as one side (the right side) of the noise-proof member110covering the compressor211. Also, in this case, similar to the configuration ofFIG. 4, the compressor211is configured such that one side (the left side), among the entire six sides surrounding the compressor211, is opened, which is more effective, in terms of noise suppressing effect, than the structure in which two sides (i.e., the left side and the front side in the configuration ofFIG. 3) are opened.

Here, like the first extending member111and the upper extending member112, the second extending member extends from the installation member120so as to be integrally formed with the installation member120. Since the noise-proof member110is integrally formed with the installation member120, the noise-proof member110is not required to be separately assembled, improving assembly characteristics.

Meanwhile, as illustrated inFIGS. 6 and 7, the compressor noise suppressing structure100according to an embodiment of the present invention may further include a detachable soundproof member170attached to the noise-proof member to cover the compressor211, in association with the noise-proof member110.

In detail, it is not easy to fabricate the noise-proof member110covering several sides of the compressor211such that it extends from the installation member120so as to be integrally formed with the installation member120, in terms of a mold structure. Also, it is difficult to assemble a plurality of connection pipes250and wirings connected to the compressor. Thus, the detachable soundproof member170may be configured as a separate component, the compressor211and the connection pipes250and wirings connected to the compressor211are installed, and the detachable soundproof member170may be subsequently attached to the noise-proof member110and/or the installation member120.

Here, as illustrated inFIGS. 6 and 7, the detachable soundproof member170includes a front covering portion171extending to the compressor211from the installation member120on the opposite side of the first extending member111to cover one side (the front side) of the compressor211and an upper covering portion172covering an upper side of the compressor211together with the upper extending member122.

However, as described hereinafter, when heat dissipation efficiency is weighed relative to a noise-proof effect through the detachable soundproof member170, the detachable soundproof member170may not be installed, the upper covering portion172of the detachable soundproof member170may not be provided, or an opening may be formed in the upper covering portion172to reduce a reduction in the heat dissipation effect due to the detachable soundproof member170. Whether to employ the detachable soundproof member170, a size and a shape of the surface covering the compressor211, and the like, may be regulated based on capacity (e.g., capacity of the evaporator) of the refrigerating system including the compressor211.

Meanwhile, the compressor may only be covered with one of the upper extending member112, the first extending member111, the second extending member114, and the bent member114of the noise-proof member110.

In this manner, when the noise-proof member110is covered with the noise-proof member110with at least one side thereof opened, noise of the compressor211can be suppressed and heat generated by the compressor211can be effectively dissipated.

Meanwhile, the compressor noise suppressing structure100may be included in the dehumidifier200according to an embodiment of the present invention. The dehumidifier200using a refrigerating cycle employs the compressor211.

As illustrated inFIGS. 8 and 9, a dehumidification unit210removing moisture from air introduced to the dehumidifier200may include the compressor211compressing a heat exchange refrigerant into a high temperature high pressure refrigerant, a condenser214emitting heat of the refrigerant compressed by the compressor211to have a high temperature and high pressure, a capillary tube213lowering pressure of the refrigerant having pressure increased by the condenser214, and an evaporator212evaporating the refrigerant passing through the capillary tube213to decrease a temperature thereof to thus change vapor in the air into water to remove moisture. Also, besides the dehumidification unit210, the dehumidifier200may include the blowing unit220discharging dehumidified air to the outside.

Here, when the dehumidifier200operates, noise generated by the compressor211may be suppressed by the noise-proof member110and/or the soundproof members140,151,152,160, and170, or the like, as described hereinafter.

Also, the dehumidifier200according to an embodiment of the present invention may allow a component, e.g., the condenser214, used in the dehumidification unit210, to be installed and supported in the installation member120of the compressor noise suppressing structure100. Also, the compressor noise suppressing structure100accommodating the water storage tank240storing condensed water generated by the condenser214during a dehumidification process may be included in the dehumidifier200.

Meanwhile, as illustrated inFIGS. 10 to 12, the compressor noise suppressing structure100according to another embodiment of the present invention may further include a blowing unit side soundproof member140extending from one side of the blowing unit220provided above the installation member120to an upper portion of the compressor211or the installation member120.

In order to suppress noise generated by the compressor211from being transmitted to an upper end of the compressor211, the blowing unit side soundproof member140may be provided in an upper portion of the compressor211to simultaneously block noise together with the noise-proof member110.

Namely, noise generated by the compressor211is primarily blocked by the noise-proof member110, and when a sound absorbing member is attached to the blowing unit side soundproof member140, the noise may be secondarily absorbed by the sound absorbing member, providing a noise blocking effect. In this case, the sound absorbing member attached to the blowing unit side soundproof member140is installed at a certain distance from the compressor211, so it does not directly affect heat dissipation of the compressor211.

Also, when a sound absorbing member is not attached to the blowing unit side soundproof member140, the blowing unit side soundproof member140may be configured to reflect noise, rather than absorbing it, to thus suppress noise from being transmitted to an upper side of the compressor211.

In this case, in order to reflect noise generated by the compressor211, the blowing unit side soundproof member140may have a surface having a curved shape covering an upper portion of the compressor.

Also, the compressor noise suppressing structure100according to another embodiment of the present invention may thither include a downwardly extending soundproof member151extending from one side of the blowing unit220to an upper end of the installation member120.

The downwardly extending soundproof member151may extend from one side of the blowing unit220toward the installation member120to suppress noise generated by the compressor212from being transmitted to the upper end of the humidifier200.

Also, a plurality of downwardly extending soundproof members may be provided to obtain a noise suppressing effect, and when a plurality of downwardly extending soundproof members are provided, noise can be more effectively blocked.

Meanwhile, the compressor noise suppressing structure100according to another embodiment of the present invention may further include an upwardly extending soundproof member152extending from an upper portion of the installation member120. In this case, the upwardly extending soundproof member152may extend from an upper portion of the installation member120toward the blowing unit220.

A plurality of upwardly extending soundproof members may be provided to obtain a noise suppressing effect, and when a plurality of upwardly extending soundproof members are provided, noise can be more effectively blocked.

Preferably, in order to improve assembly characteristics, the upwardly extending soundproof member152is integrally formed with the installation member120, like the noise-proof member110, but the present invention is not limited thereto.

Meanwhile, as illustrated inFIG. 10, referring to an enlarged view of the downwardly extending soundproof member151and the upwardly extending soundproof member152, the downwardly extending soundproof member151may extend from the blowing unit220toward the installation member120, and the upwardly extending soundproof member152may extend from the installation member120toward the blowing unit220. The downwardly extending soundproof member151and the upwardly extending soundproof member152may be adjacent and parallel to each other.

In such a case, the downwardly extending soundproof member151is not directly in contact with the installation member120, and the upwardly extending soundproof member152is not directly in contact with the blowing unit220, whereby the downwardly extending soundproof member151or the upwardly extending soundproof member152is prevented from being brought into contact with the blowing unit220or the installation member120due to vibrations when the compressor211is operated to damage the blowing unit220or the installation member120or generate noise.

Also, since the downwardly extending soundproof member151and the upwardly extending soundproof member152are positioned to be adjacent and parallel to each other, noise can be simultaneously blocked.

Meanwhile, referring toFIGS. 10 through 12, in order to suppress noise generated by the compressor211from being transmitted to a lateral surface of the installation member120, a laterally extending soundproof member160may be disposed on a lateral surface of the installation member120such that it extends from the lateral surface of the installation member120toward the housing230.

As illustrated inFIG. 12, the laterally extending soundproof member160may be installed to be spaced apart from the housing230so that it cannot be in contact with the housing230due to vibrations of the compressor211, or the like.

Meanwhile, inFIGS. 10 through 12, it is illustrated that the laterally extending soundproof member160is only disposed on one surface of the installation member120, but the present invention is not limited thereto and the laterally extending soundproof member160may be provided on a left portion, a right portion, or both of the left and right portions of the installation member120.

In order to improve assembly characteristics, the laterally extending soundproof member160may be integrally formed with the installation member120, like the noise-proof member110, but the present invention is not limited thereto.

Hereinafter, an operation and effect of the compressor noise suppressing structure100and the dehumidifier200according to embodiments of the present invention will be described in detail.

When a refrigerator or the dehumidifier200employing the compressor211operates, noise is generated by the compressor. The compressor noise suppressing structure100according to an embodiment of the present invention is configured to surround the compressor211to block noise generated when the compressor211is operated.

A desirable structure for blocking noise of the compressor211is a configuration of a noise-proof member110covering the entire surfaces of the compressor211. In this case, however, it is difficult to install the connection pipes150connecting the compressor211to other components such as the condenser214, so the structure may be configured to have a configuration in which one side of the surfaces covering the compressor211is opened. In addition, when the entire surfaces of the compressor211are covered with the noise-proof member110, heat generated by the compressor211cannot be effectively dissipated to increase a temperature of the compressor211and a load to increase vibrations of the compressor211. When vibrations generated by the compressor211are increased, they serve as an additional noise generation source as being disadvantageous in terms of noise blocking.

Thus, as illustrated inFIGS. 3 through 5, the compressor noise suppressing structure100according to an embodiment of the present invention may have a structure in which two sides or one side thereof are opened. In this case, the structure with two open side may have a less noise suppressing effect relative to the structure with one open side, but can effectively dissipate heat generated when the compressor211is operated, obtaining an effect of reducing noise generation due to an increased temperature.

Also, the noise blocking effect may be further increased when the partition122is disposed in a portion, of the installation member120, from which the noise-proof member110extends, because noise is blocked by the partition122.

Namely, noise generated by the compressor211is primarily blocked by the compressor noise suppressing structure100according to an embodiment of the present invention and secondarily blocked by the housing230, whereby noise can be blocked simultaneously.

Also, in the case of the dehumidifier200, the condenser214, the capillary tube213, the evaporator212, the blowing unit220, and the like, may be coupled to the upper surface of the mounting surface121, whereby space within the dehumidifier200can be more effectively utilized.

In the compressor noise suppressing structure100according to an embodiment of the present invention, since the installation member120and the noise-proof member110extending from the installation member120are formed as a single component, assembly costs can be reduced and fabrication process is simplified relative to the case in which the installation member120and the noise-proof member110are separately configured as different components.

The noise suppressing effect of the compressor noise suppressing structure100having the foregoing configuration according to an embodiment of the present invention is as shown in Table 1 below.

In Table 1, Embodiment 1 shows noise measurement experiment results of the compressor noise suppressing structure100in which a front side of the compressor is exposed and a portion of a left side and a portion of an upper side are exposed as illustrated inFIG. 4. It can be seen that average noise of the three cases were measured as approximately 35.7 dB.

Embodiment 2 shows noise measurement experiment results of the compressor noise suppressing structure100further including the detachable soundproof member170. It can be seen that average noise of the three cases was measured as approximately 36.7 dB.

In the comparative example, a sound absorbing unit was installed on a circumference of the compressor211, without the noise-proof member110according to an embodiment of the present invention. It can be seen that average noise was measured as approximately 37.6 dB.

According to the results, in the case of Embodiment 1 and Embodiment 2 in which the noise-proof member110according to an embodiment of the present invention is installed, it can be seen that noise of about 2 dB was reduced in comparison to comparative example without the noise-proof member.

Also, Embodiment 1 and Embodiment 2 have lower noise levels than that of comparative example, and it can be seen that the structure in which at least one side of the compressor is opened to easily dissipate heat generated by the compressor211has a high noise reduction effect. However, as illustrated inFIGS. 6 and 7, the present invention does not exclude an embodiment in which the detachable soundproof member170is installed, and a heat dissipation structure of the compressor211may be achieved according to a shape of the detachable soundproof member170.

Meanwhile, the compressor noise suppressing structure100according to another embodiment of the present invention may include a blowing unit side soundproof member104, the downwardly extending soundproof member151, the upwardly extending soundproof member152, and the laterally extending soundproof member160.

Noise generated by the compressor211is primarily blocked by the noise-proof member110. However, leaked noise is transmitted to an upper portion of the dehumidifier200through the blowing unit220provided on an upper surface of the noise-proof member110or transmitted along a left side or a right side of the installation member120.

First, the blowing unit side soundproof member140is provided on an upper end of the compressor211. The blowing unit side soundproof member140blocks or reflects noise transmitted to the upper end of the compressor211, rather than having been primarily blocked by the noise-proof member110to suppress noise from moving to an upper end of the dehumidifier200along the blowing unit220.

Also, the downwardly extending soundproof member151and the upwardly extending soundproof member152suppress noise not blocked by the noise-proof member from being transmitted to an upper side of the dehumidifier200through space formed between the blowing unit220and the installation member120.

The downwardly extending soundproof member151extends from one side of the blowing unit220and the upwardly extending soundproof member152extends from an upper end of the installation member120such that space is formed between the blowing unit220and the installation member120, effectively blocking noise.

In particular, when the downwardly extending soundproof member151and the upwardly extending soundproof member152are disposed to be adjacent and parallel to each other, noise can be simultaneously blocked, and when a plurality of downwardly extending soundproof members151and a plurality of upwardly extending soundproof member151are provided, noise can be more effectively blocked.

Also, noise not blocked by the noise-proof member110is transmitted along the left or right side of the installation member120. The laterally extending soundproof member160has an effect of blocking noise transmitted along the lateral surface of the installation member120.
