본 발명은 냉장고에 관한 것으로, 보다 상세하게는 냉장고용 방열장치의 소음 및 진동을 저감시키기 위한 기계실에 관한 것이다.The present invention relates to a refrigerator, and more particularly to a machine room for reducing the noise and vibration of the heat radiation device for a refrigerator.

일반적으로, 냉장고는 냉매를 고온고압으로 압축시키는 압축기(compressor)와, 상기 압축기로부터 보내진 냉매를 방열하여 고온고압 상태의 액상냉매로 변환시키는 응축기(condenser)와, 상기 응축기를 통과한 고온고압 상태의 냉매가 통과되면서 저온저압의 액상냉매로 변환시키는 모세관과, 상기 모세관을 통해 저온저압 상태로 된 냉매를 기화시키면서 공기와 열교환시키는 증발기(evaporator)를 포함한다.In general, a refrigerator includes a compressor for compressing a refrigerant at a high temperature and high pressure, a condenser for dissipating the refrigerant sent from the compressor and converting the refrigerant into a liquid refrigerant at a high temperature and high pressure, and a high temperature and high pressure passing through the condenser. Capillary tube for converting into a low-temperature low-pressure liquid refrigerant while passing through the refrigerant, and an evaporator (exvaporator) for heat exchange with the air while vaporizing the refrigerant at a low-temperature low-pressure state through the capillary.

여기서, 증발기는 외기와 차단되어 저온상태를 유지해야 하고 내부의 공기와 접촉이 용이해야 하지만, 이 과정에서 공기 중에 있는 습기가 낮은 온도의 증발기와 접촉하게 되면 그 습기는 응축하여 성에로 변화하고 증발기에 착상하게 된다.Here, the evaporator should be kept at a low temperature by being blocked from the outside air and easy to contact with the air inside. However, when the moisture in the air comes into contact with the evaporator of low temperature, the moisture condenses to frost and the evaporator Is conceived.

이러한 성에는 증발기의 열교환 효율을 저하시키기 때문에 냉장고의 제어부에 의해 제어되는 제상히터를 작동시켜 제거시키게 된다.In this case, since the heat exchange efficiency of the evaporator is lowered, the defrost heater controlled by the control unit of the refrigerator is removed.

이와 같은 과정으로 성에가 제거되면서 생성된 제상수는 기계실로 제공된다.The defrost water generated by the defrosting process is provided to the machine room.

한편, 도 1 내지 도 3에 도시된 바와 같이 기계실(8)에는 방열장치가 구비된다.On the other hand, as shown in Figures 1 to 3 the machine room 8 is provided with a heat radiating device.

이러한 방열장치는, 압축기(1)로부터 제공받은 냉매를 방열하여 고온고압 상태의 액상냉매로 변환시키도록 코일형태의 방열파이프(3)로 이루어진 응축기(2)와, 상기 응축기(2)의 일측에 구비되어 상기 압축기(1) 및 응축기(2)에서 발생되는 열을 방출시키도록 회전하는 블로워유닛(4)과, 상기 응축기(2)의 하부에 구비되고 증발기(미도시)로부터 발생된 제상수를 배수호스(6)로부터 제공받아 집수하는 증발명(evaporation vessel; 5)으로 이루어진다.The heat dissipation device includes a condenser (2) made of a coil-type heat dissipation pipe (3) to dissipate the refrigerant provided from the compressor (1) and convert it into a liquid refrigerant in a high temperature and high pressure state, and on one side of the condenser (2). And a blower unit 4 which rotates to discharge heat generated by the compressor 1 and the condenser 2, and a defrost water which is provided under the condenser 2 and is generated from an evaporator (not shown). It consists of an evaporation vessel (5), which is received from the drain hose 6 and collected.

상기 압축기(1), 응축기(2), 블로워유닛(4), 및 증발명(5)은 지지판(8a)의 상부에 구비된다.The compressor 1, the condenser 2, the blower unit 4, and the evaporation name 5 are provided on the support plate 8a.

그리고 블로워유닛(4)은 송풍팬(4a) 및 모터(4b)로 이루어지고, 이 중 모터(4b)는 고정구(7)에 의해 고정된다.The blower unit 4 is composed of a blowing fan 4a and a motor 4b, among which the motor 4b is fixed by the fixture 7.

상기 블로워유닛(4)의 가동으로 기계실(8)의 흡입구(9)로 유입된 바람에 의해 증발명(5)에 집수된 제상수를 증발시킴과 동시에 응축기(2)의 방열파이프(3)를 흐르는 고온의 냉매 및 압축기(1)에서 발생된 열을 냉각시키게 된다.By operating the blower unit 4, the defrost water collected in the evaporation name 5 is evaporated by the wind flowing into the suction port 9 of the machine room 8, and at the same time, the heat dissipation pipe 3 of the condenser 2 is removed. It cools the flowing high temperature refrigerant and the heat generated by the compressor (1).

하지만, 종래기술에 따른 냉장고용 기계실(8)은 방열장치를 구성하는 압축기(1)와 블로워유닛(4)에서 발생된 소음 및 진동이 기계실(8)의 내부에서 저감되지 못하고, 오히려 소음 및 진동이 기계실(8)의 흡입구(9)를 통해서 사용자들에게 직접 전달되도록 설계되므로, 사용자들이 정신적으로 불안감과 불쾌함을 가질 소지가 다분할 뿐만 아니라, 제품에 대한 신뢰감을 떨어뜨리는 문제점이 있었다.However, in the refrigerator machine room 8 according to the related art, the noise and vibration generated in the compressor 1 and the blower unit 4 constituting the heat dissipation device are not reduced within the machine room 8, but rather the noise and vibration. Since it is designed to be delivered directly to the user through the suction port 9 of the machine room 8, there is a problem that the users are not only mentally anxious and unpleasant, but also lower the confidence in the product.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 방열장치를 구성하는 압축기와 블로워유닛에서 발생된 소음 및 진동이 내부에서 저감되도록 하는 냉장고용 방열장치의 소음 및 진동을 저감시키기 위한 기계실을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, a machine room for reducing the noise and vibration of the radiator for the refrigerator to reduce the noise and vibration generated in the compressor and blower unit constituting the radiator therein.

상기 내부 벽은, 일측에 공기가 흡입되는 흡입유로와 타측에 공기가 토출되는 토출유로를 형성하되, 상기 흡입유로와 토출유로는 적어도 한번 이상 굴곡 형성된 것이 바람직하다.The inner wall may form a suction passage through which air is sucked on one side and a discharge passage through which air is discharged to the other side, and the suction passage and the discharge passage may be bent at least once.

상기 내부 벽 전체 또는 상기 흡입유로 및 토출유로는 공기와 접촉하는 부위가 흡음재로 이루어진다.The entire inner wall or the suction passage and the discharge passage are made of sound absorbing material in contact with air.

이하, 첨부된 도면을 참조하여 본 발명에 따른 냉장고용 방열장치의 소음 및 진동을 저감시키기 위한 기계실에 관한 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the machine room for reducing the noise and vibration of the heat radiation device for a refrigerator according to the present invention.

도 4는 본 발명에 따른 냉장고용 방열장치의 소음 및 진동을 저감시키기 위한 기계실을 개략적으로 도시한 구성도이다.Figure 4 is a schematic diagram showing a machine room for reducing the noise and vibration of the heat radiation device for a refrigerator according to the present invention.

도 4에 도시된 바와 같이, 본 발명에 따른 냉장고용 방열장치(20)의 소음 및 진동을 저감시키기 위한 기계실(10)은, 도 3에 도시된 종래기술과 달리 방열장치(20)를 구성하는 압축기(21)와 블로워유닛(22)으로부터 발생되는 소음 및 진동을 저감시키도록 케이스(11)의 내부 벽(12)이 다수회 굴곡진 형태를 가진다.As shown in FIG. 4, the machine room 10 for reducing the noise and vibration of the heat dissipation device 20 for a refrigerator according to the present invention, unlike the prior art shown in FIG. 3, constitutes the heat dissipation device 20. In order to reduce noise and vibration generated from the compressor 21 and the blower unit 22, the inner wall 12 of the case 11 has a curved shape a plurality of times.

여기서, 방열장치(20)의 구성 및 그에 따른 작용은 발명이 속하는 기술분야 및 그 분야의 종래기술에서 이미 설명되어 있으므로, 하기에는 본 발명과 밀접한 관련이 있는 압축기(21)와 블로워유닛(22)을 위주로 설명될 것이다. 참고로, 미설명된 도면부호 '23'은 응축기이다.Here, since the configuration of the heat dissipation device 20 and its operation are already described in the technical field to which the invention pertains and the prior art in the field, the compressor 21 and the blower unit 22 which are closely related to the present invention will be described below. It will be explained mainly. For reference, reference numeral '23', which is not described, is a condenser.

실시예에서, 케이스(11)의 내부 벽(12)은 일측에 공기가 흡입되는 흡입유로(24)와 타측에 공기가 토출되는 토출유로(25)를 형성한다.In an embodiment, the inner wall 12 of the case 11 forms a suction passage 24 through which air is sucked on one side and a discharge passage 25 through which air is discharged to the other side.

이 흡입유로(24)와 토출유로(25)는 적어도 한번 이상 굴곡 형성되는 것이 바람직하다(A구간과 E구간).It is preferable that the suction flow passage 24 and the discharge flow passage 25 are formed at least one bend (section A and section E).

이와 같이, 흡입유로와(24) 토출유로(25)가 적어도 한번 이상 굴곡 형성되므로서, 공기 유동에 따른 소음의 발생을 어느 정도 저감시킬 수 있고, 압축기(21)와 블로워유닛(22)에서 발생하는 소음 및 진동이 외부로 누출되는 것을 억제할 수 있 는 장점이 있다.In this way, since the suction passage 24 and the discharge passage 25 are bent at least once, the generation of noise due to the air flow can be reduced to some extent, and the compressor 21 and the blower unit 22 are generated. There is an advantage that can suppress the leakage of noise and vibration to the outside.

그리고 케이스(11)의 내부 벽(12) 전체 또는 상기 흡입유로(24) 및 토출유로(25)는 공기와 접촉하는 부위가 흡음재로 이루어진다.The entire inner wall 12 of the case 11 or the suction passage 24 and the discharge passage 25 are made of sound absorbing material in contact with air.

여기서, 흡음재는 건축과 산업현장에서 널리 이용되고 있으며, 이러한 흡음재는 이미 공지된 기술이므로, 그에 대한 상세한 설명은 생략한다.Here, the sound absorbing material is widely used in construction and industrial sites, and since such sound absorbing material is already known, a detailed description thereof will be omitted.

이와 같이, 내부 벽(12) 전체 또는 상기 흡입유로(24) 및 토출유로(25)는 공기와 접촉하는 부위가 흡음재로 이루어지므로, 공기 유동에 따른 소음뿐만 아니라, 압축기(21)와 블로워유닛(22)에서 발생하는 소음 및 진동을 최대한 감소시킬 수 있다.As such, the entire inner wall 12 or the suction flow passage 24 and the discharge flow passage 25 are made of sound absorbing material in contact with air, so that not only the noise caused by the air flow, but also the compressor 21 and the blower unit ( The noise and vibration generated in 22) can be reduced as much as possible.

이 케이스(11)의 내부 벽(12)은 상기 블로워유닛(22)이 설치된 구간에서 폭(h)이 가장 협소해지는 것이 바람직하다(C구간).The inner wall 12 of the case 11 preferably has the narrowest width h in the section in which the blower unit 22 is installed (section C).

구체적으로, 케이스(11)의 내부 벽(12)은 120Hz 내지 315Hz 대역의 주파수를 상쇄시키도록 좌우 길이방향의 단면 형상이 120Hz 내지 315Hz 대역의 주파수를 리사이클(Recycle)하여 굴곡 형성된다(A구간 내지 E구간).Specifically, the inner wall 12 of the case 11 is bent by recycling the frequency of the 120Hz to 315Hz band in the cross-sectional shape in the left and right directions so as to cancel the frequency of the 120Hz to 315Hz band (A section to Section E).

즉, 방열장치(20)에서 주 소음원 및 진동원인 압축기(21)는 주로 60~500Hz 대역의 주파수를 가지고, 블로워유닛(22)은 주로 120~315Hz 대역의 주파수를 가진다.That is, in the radiator 20, the compressor 21, which is the main noise source and the vibration source, mainly has a frequency in a 60 to 500 Hz band, and the blower unit 22 mainly has a frequency in a 120 to 315 Hz band.

이에 따라, 케이스(11)의 내부 벽(12) 좌우 길이방향의 단면 형상이 120Hz 내지 315Hz 대역의 주파수를 리사이클하여 굴곡 형성한다면, 상기와 같은 압축기(21)와 블로워유닛(22)의 주파수를 어느 정도 상쇄시킬 수 있고, 이로 인해 압축기 (21)와 블로워유닛(22)에서 발생하는 소음을 일부(대략, 소음 중 5~6dB 정도)를 저감시킬 수 있는 효과가 있다.Accordingly, if the cross-sectional shape in the left and right longitudinal directions of the inner wall 12 of the case 11 is formed by recycling the frequencies in the 120 Hz to 315 Hz band, the frequencies of the compressor 21 and the blower unit 22 as described above may be changed. It is possible to offset the accuracy, thereby reducing the noise generated in the compressor 21 and the blower unit 22 (approximately, about 5 to 6 dB of the noise) can be reduced.

상기와 같이 내부 벽(12)의 좌우 길이방향의 단면 형상이 120Hz 내지 315Hz 대역의 주파수를 리사이클하여 굴곡 형성하기 때문에, 결국 블로워유닛(22)이 설치된 구간(C구간)에서 폭이 가장 협소해지도록 설계되게 된다.Since the cross-sectional shape in the left and right longitudinal directions of the inner wall 12 is formed to bend by recycling the frequency of the 120 Hz to 315 Hz band, the width becomes narrowest in the section (section C) where the blower unit 22 is installed. Will be designed.

한편, 케이스(11)는 복수의 방진구(30)에 의해 지지되는 것이 바람직하다.On the other hand, the case 11 is preferably supported by a plurality of dustproof openings (30).

여기서, 방진구(30)는 고무, 우레탄, 실리콘, 코일스프링, 판스프링 중 어느 하나인 것이 바람직하다. 이 방진구(30)는 지지판(31)으로 지지되는 것이 바람직하다.Here, the vibration isolator 30 is preferably any one of rubber, urethane, silicone, coil spring, leaf spring. This vibration isolator 30 is preferably supported by a support plate 31.

상기한 방진구(30)에 의해 본 발명에 따른 기계실(10) 전체에서 발생하는 진동과 이 진동에 의해 발생되는 소음을 효과적으로 저감시킬 수 있다.By the above-mentioned dustproof port 30, the vibration generated in the entire machine room 10 and the noise generated by the vibration can be effectively reduced.

본 발명은 냉장고용 방열장치의 소음 및 진동을 저감시키기 위한 기계실에 관한 것으로, 케이스의 내부 벽이 다수회 굴곡진 형태를 가지고 복수의 방진구에 의해 지지되므로서, 방열장치에서 압축기와 블로워유닛으로부터 발생되는 소음 및 진동을 효울적으로 저감시킬 수 있는 우수한 효과가 있다.The present invention relates to a machine room for reducing the noise and vibration of the heat dissipation device for a refrigerator, wherein the inner wall of the case has a curved shape a plurality of times and is supported by a plurality of dustproof openings. There is an excellent effect that can effectively reduce the noise and vibration generated.
