Description

  The present invention relates to a sound insulation member and a cooling device.

  Conventionally, a prefabricated refrigerator manufactured by combining constituent members such as a heat insulating panel in the field is known (for example, see Patent Document 1). In this prefabricated refrigerator, a refrigerator main body that accommodates an object to be refrigerated is formed by combining a heat insulating panel, and a cooling unit for cooling the inside of the refrigerator main body is attached to the refrigerator main body.

FIG. 8 shows an example of the structure of the prefabricated refrigerator. In this prefabricated refrigerator, the cooling unit 104 is attached to the top wall portion 102a of the refrigerator main body 102, and the outside 104a of the cooling unit 104 is installed on the top wall portion 102a. The refrigerator exterior 104a of the cooling unit 104 has a configuration in which a condenser, a compressor, an evaporator, a blower fan, electrical components, and the like (not shown) are housed in a housing 105. One side wall 105 a of the housing 105 is provided with an air inlet 105 b for taking air into the housing 105. And the said condenser is installed in the position close | similar to the said inlet 105b in the housing | casing 105, A refrigerant gas is condensed with the said condenser using the air taken in through the inlet 105b. ing.
JP-A-5-18653

  In the prefabricated refrigerator described above, there is a risk that noises such as the compressor in the housing 105 and the motor of the blower fan leak out from the intake port 105b in the outside 104a of the cooling unit 104. The noise leaked from the air inlet 105b has a disadvantage that it is directly transmitted to the people around the prefabricated refrigerator due to the air inlet 105b being provided on the side wall 105a of the casing 105 of the exterior 104a.

  Incidentally, in Japanese Patent Laid-Open No. 2001-108262, for the purpose of reducing the noise generated from the outdoor unit of the air conditioner, a sound insulating member such as a silent hood is provided so as to cover the air outlet of the outdoor unit. It is disclosed. Therefore, it is also conceivable to reduce noise by providing such a sound insulating member at the intake port 105b of the outside 104a of the cooling unit 104.

  However, since the cooling unit 104 is installed on the ceiling wall portion 102a of the refrigerator main body 102, when an operator attaches the sound insulation member to the cooling unit 104 later, a complicated mounting operation is performed on the ceiling wall portion 102a. It is desirable that the sound insulating member can be attached to the cooling unit 104 as easily as possible.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to enable a sound insulation member to be easily retrofitted to a cooling unit installed on a top wall portion of a refrigerator body. .

  In order to achieve the above object, the sound insulation member according to the present invention is provided with an outside of a cooling unit for cooling the inside of the refrigerator body on the top wall portion of the refrigerator body that houses the object to be refrigerated. A sound insulation member attached to a prefabricated refrigerator provided with an air inlet on a side wall of a housing outside the cabinet, provided with a sound insulation wall disposed outside the air inlet, and provided on the sound insulation wall, And an attachment portion configured to be attachable by magnetic force.

  The sound insulation member is configured such that the attachment portion provided on the sound insulation wall can be attached to the housing outside the storage of the cooling unit by a magnetic force, so that the attachment portion contacts the housing outside the storage of the cooling unit. The sound insulation member can be attached to the outside of the cooling unit alone. For this reason, even when the cooling unit is installed on the top wall of the refrigerator main body, the sound insulating member can be easily placed outside the cooling unit without an operator performing complicated work on the top wall of the refrigerator main body. Can be attached. Therefore, with this sound insulating member, it can be easily retrofitted to the cooling unit installed on the top wall of the refrigerator body.

  Further, the sound insulation member according to the present invention is provided with an outside of a cooling unit for cooling the inside of the refrigerator main body on the top wall portion of the refrigerator main body that houses the object to be refrigerated. A sound insulating member attached to a prefabricated refrigerator having an air inlet on the side wall, and is provided on the sound insulating wall disposed outside the air inlet and on the sound insulating wall, and can be hooked at a predetermined position of the casing outside the warehouse. And a latching portion configured as described above.

  The sound insulation member is configured such that the latching portion provided on the sound insulation wall can be latched at a predetermined location on the housing outside the refrigerator unit, so that the latching portion is provided at a predetermined location on the cabinet outside the cabinet. The sound insulation member can be attached to the outside of the cooling unit simply by being hooked on the cooling unit. For this reason, even when the cooling unit is installed on the top wall of the refrigerator main body, the sound insulating member can be easily placed outside the cooling unit without an operator performing complicated work on the top wall of the refrigerator main body. Can be attached. Therefore, with this sound insulating member, it can be easily retrofitted to the cooling unit installed on the top wall of the refrigerator body.

  In the sound insulation member, it is preferable that the sound insulation wall is installed outside the intake port so as to open upward. If comprised in this way, the intake of the air from the said inlet into the store | casing exterior of a cooling unit can be made easy through opening of a sound insulation wall. Further, in this configuration, since the sound insulation wall is installed outside the intake port so as to open upward, even if noise leaks to the outside through the opening of the sound insulation wall, the noise passes upward, and the prefabricated refrigerator It is difficult to convey to the side, that is, people around the prefabricated refrigerator. Therefore, with this configuration, it is possible to reduce noise transmitted to people around the prefabricated refrigerator while facilitating the intake of air into the outside of the cooling unit. Further, when the sound insulation wall is installed outside the intake port so as to open on the side surface, the flow of air flowing through the opening to the intake port is a horizontal flow from the side of the sound insulation wall. The sound generated by the air flow is easily transmitted to people on the side of the prefabricated refrigerator. On the other hand, in the above configuration, since the upper surface of the sound insulation wall is open, the flow of air flowing through the opening to the intake port is a flow from the upper side to the lower side. For this reason, compared with the case where the side surface of the sound insulation wall is opened, it is possible to make it difficult for a person at the side of the prefabricated refrigerator to hear noise caused by the flow of air from the opening of the sound insulation wall to the intake port.

  In the sound insulating member, it is preferable that a sound insulating material is provided on the sound insulating wall. If comprised in this way, it can suppress more that the noise leaked from the said inlet port is transmitted to the person around the prefabricated refrigerator by a soundproof material.

  The sound insulating member of the cooling unit preferably includes a sealing material for closing a gap between the sound insulating wall and the outer surface of the external housing. If comprised in this way, since the clearance gap between the sound-insulating wall and the outer surface of the housing | casing outside the cooling unit housing | casing can be obstruct | occluded with a sealing material, it can suppress that noise leaks through this clearance gap. . For this reason, it can suppress more that the noise which leaks from the said inlet port is transmitted to the person around the prefabricated refrigerator.

  The cooling device according to the present invention is a cooling device including a cooling unit for cooling the inside of the refrigerator main body and a sound insulating member having the attachment portion, and a housing outside the storage of the cooling unit includes the A recess for fitting the attachment portion of the sound insulation member is formed.

  In this cooling device, since the recess for fitting the mounting portion of the sound insulation member is formed in the housing outside the cooling unit, the sound insulation member is attached to the housing outside the cooling unit after mounting the sound insulation member. It is possible to prevent the member from being displaced relative to the outside of the cooling unit.

  As described above, according to the present invention, the sound insulation member can be easily retrofitted to the cooling unit installed on the top wall of the refrigerator body.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The cooling unit 6 generates cool air and cools the inside of the refrigerator body 2 by supplying the cool air into the refrigerator body. This cooling unit 6 is comprised by the warehouse exterior 10 and the ventilation duct not shown.

  The warehouse exterior 10 is installed on the top wall 2 a of the refrigerator body 2. As shown in FIG. 2, the exterior 10 includes a housing 12, a heat insulating portion 13, a condenser 14, a condenser fan 16, an evaporator 18, an evaporator fan 20, a compressor 22, An expansion mechanism 24 and an electrical component 26 are included.

  The housing 12 is a hollow box formed by bending a sheet metal. Inside the housing 12, a heat insulating portion 13, a condenser 14, a condenser fan 16, an evaporator 18, and an evaporator are used. The fan 20, the compressor 22, the expansion mechanism 24, and the electrical component 26 are accommodated. That is, the cooling unit 6 according to the present embodiment is an integrated cooling unit in which both the condenser 14 and the evaporator 18 are housed in the housing 12 of the exterior 10.

  And the space in the housing | casing 12 is divided into 1st chamber S1 and 2nd chamber S2 by the heat insulation part 13. FIG. The heat insulating portion 13 is configured in a box shape, and is installed in the housing 12 at a position in the vicinity of the side wall 12 a on the back side that constitutes the housing 12. The first chamber S <b> 1 is a space surrounded by the heat insulating portion 13, and the second chamber S <b> 2 is a space other than the space surrounded by the heat insulating portion 13 in the housing 12. And between the said 1st chamber S1 and the said 2nd chamber S2 is thermally insulated by the heat insulation part 13, The inside of the said 1st chamber S1 can be hold | maintained to low temperature.

  An unillustrated opening is formed in a portion of the top wall 2a of the refrigerator body 2 corresponding to the first chamber S1, and an unillustrated air duct extending into the refrigerator body 2 is connected to the opening. ing. That is, the first chamber S1 and the refrigerator body 2 communicate with each other through the air duct not shown.

  In addition, an air inlet 12 c for taking air into the housing 12 is provided on the side wall 12 b on the front side constituting the housing 12. Further, an exhaust port 12 e for exhausting air from the inside of the housing 12 is provided in the ceiling wall 12 d (see FIG. 1) of the housing 12.

  The condenser 14 condenses the refrigerant gas by heat exchange with external air taken into the housing 12 through the intake port 12c. The condenser 14 is installed in the second chamber S2 in the housing 12 at a position close to the intake port 12c.

  The condenser fan 16 is driven by a motor and sucks air to be used for heat exchange in the condenser 14 from the intake port 12c. The condenser fan 16 is disposed in the second chamber S2 in the housing 12 on the side opposite to the intake port 12c with respect to the condenser 14. The air sucked by the condenser fan 16 is used for heat exchange in the condenser 14 and then discharged to the outside through the exhaust port 12 e of the housing 12.

  The evaporator 18 is installed in the first chamber S1 in the heat insulating portion 13. The evaporator 18 generates cold air using a low-temperature refrigerant liquid that flows from the condenser 14 via the expansion mechanism 24. Specifically, in the evaporator 18, cold air is generated by heat exchange between the low-temperature refrigerant liquid and air introduced from the refrigerator main body 2. The refrigerant liquid used for heat exchange evaporates into refrigerant gas and is sucked into the compressor 22.

  The evaporator fan 20 is driven by a motor and blows the cool air generated by the evaporator 18 into the refrigerator body 2 through the air duct not shown. Thus, when the cool air is blown into the refrigerator main body 2, the inside of the refrigerator main body 2 is cooled. The evaporator fan 20 is disposed on the opposite side of the side wall 12 a on the back side of the housing 12 with respect to the evaporator 18 in the first chamber S <b> 1 in the heat insulating portion 13.

  The compressor 22 compresses the refrigerant gas flowing from the evaporator 18 and discharges it to the condenser 14. The compressor 22 is disposed between the condenser fan 16 and the heat insulating portion 13 in the second chamber S <b> 2 in the housing 12.

  The expansion mechanism 24 converts the high-temperature and high-pressure refrigerant liquid produced by the condenser 14 into a low-temperature and low-pressure refrigerant liquid that can be easily evaporated. As the expansion mechanism 24, various expansion valves, capillary tubes, and the like are used.

  The electrical component 26 is for performing electrical control of each of the devices installed in the housing 12, and in the housing 12, the condenser 14, the condenser fan 16, and the compressor 22 side. It is arranged in the direction.

  The sound insulation member 8 according to the present embodiment is attached to the outer surface of the front side wall 12b of the exterior 10 of the cooling unit 6, and is located around the prefabricated refrigerator while blocking noise leaking from the intake port 12c. This is to reduce noise transmitted to people.

  Specifically, various kinds of noise are generated from the compressor 22 and the motor of the condenser fan 16 housed in the housing 12 of the external compartment 10. This noise leaks to the outside through the intake port 12c. At this time, if the sound insulation member 8 is not provided, the noise is directly transmitted to a person around the prefabricated refrigerator due to the intake port 12c opening in the side wall 12b on the front side of the housing 12. It is transmitted. Therefore, in the present embodiment, the sound insulating member 8 is attached so as to surround the outside of the intake port 12c, and noise leaking from the intake port 12c is blocked. The sound insulation member 8 includes a sound insulation wall 32, an attachment portion 34, and a sound insulation material 36.

  The sound insulation wall 32 blocks transmission of noise leaking from the air inlet 12c. The sound insulation wall 32 is placed on the top wall 2a of the refrigerator body 2 and is disposed outside the intake port 12c so as to surround the intake port 12c. The sound insulation wall 32 is installed so as to open upward outside the intake port 12c.

  Specifically, the sound insulation wall 32 is made of a bent sheet metal, and includes a linearly extending front wall portion 32a, and side wall portions 32b raised vertically from both longitudinal ends of the front wall portion 32a. 32b.

  The front wall portion 32a is a portion disposed so as to cover the front side of the intake port 12c. The front wall portion 32a is arranged parallel to and spaced from the side wall 12b of the housing 12. And the front wall part 32a has a dimension substantially equal to the side wall 12b of the housing | casing 12 in an up-down direction and a longitudinal direction.

  Each of the side wall portions 32b extends from the corresponding end portion of the front wall portion 32a toward the side wall 12b of the housing 12. The left and right sides of the space between the front wall 32a and the side wall 12b of the housing 12 are shielded by the side walls 32b and 32b. And each side wall part 32b has a dimension substantially equal to the side wall 12b of the housing | casing 12 and the said front wall part 32a in an up-down direction.

  And in the state in which the sound insulation wall 32 was mounted on the top wall part 2a of the refrigerator main body 2, the lower end of the said front wall part 32a and the said both-side wall parts 32b and 32b, and the upper surface of the top wall part 2a of the refrigerator main body 2 are There is no space between the front wall portion 32a and the lower side walls 32b, 32b and the top surface of the top wall portion 2a. In addition, when it is difficult to closely contact the lower end of the front wall portion 32a and the both side wall portions 32b and 32b and the upper surface of the top wall portion 2a of the refrigerator body 2, the front wall portion 32a and the both side walls A bottom portion that shields the opening on the lower end side of the portions 32b and 32b may be provided to prevent noise from leaking from the opening on the lower end side.

  In the state where the sound insulating member 8 is attached to the side wall 12b of the housing 12, the space surrounded by the front wall portion 32a and both side wall portions 32b and 32b of the sound insulating wall 32 and the side wall 12b of the housing 12 opens upward. is doing. Air is taken into the housing 12 from the air inlet 12c through this opening. At this time, the flow of air taken into the intake port 12c is a flow from the upper side to the lower side through the opening. On the other hand, the noise leaking from the air inlet 12c is blocked by the sound insulation wall 32 and the ceiling wall 2a of the refrigerator body 2, and is not directly transmitted to the side of the prefabricated refrigerator, that is, a person around the prefabricated refrigerator. Pass through and go up.

  The attachment portion 34 is provided at an end portion of each side wall portion 32b of the sound insulating wall 32 opposite to the front wall portion 32a. This attachment part 34 is a part attached to the outer surface of the side wall 12b of the housing 12 of the outside of the cabinet 10. The attachment portion 34 is configured to be attachable to the side wall 12b of the housing 12 by a magnetic force.

  Specifically, the attachment part 34 includes a fixing part 34a and a magnet 34b.

  The fixing portion 34a is a portion to which the magnet 34b is fixed, and extends from an end portion of each side wall portion 32b of the sound insulating wall 32 opposite to the front wall portion 32a. The fixing portion 34a is vertically raised inward from an end portion of the side wall portion 32b opposite to the front wall portion 32a.

  The magnet 34b is formed in a thin plate shape, and is attached to the entire outer surface of the fixed portion 34a, that is, the entire surface facing the side wall 12b of the fixed portion 34a. Due to the magnetic force of the magnet 34b, the attachment portion 34 (magnet 34b) can be attached to the outer surface of the side wall 12b simply by contacting the outer surface of the side wall 12b of the housing 12. That is, unlike the case where the sound insulating member 8 is fastened to the housing 12 with bolts and nuts, it is not necessary to open a bolt hole in the housing 12 or perform fastening work. 12 can be easily retrofitted.

  The soundproof material 36 is attached to the entire inner surface of the sound insulation wall 32. As the soundproof material 36, it is possible to use urethane foam, sponge, or other various materials generally applied to soundproof materials. By this soundproof material 36, the noise leaked from the inlet 12c is further insulated or absorbed. As a result, the noise is more difficult to be transmitted to people around the prefabricated refrigerator.

  Next, an experiment conducted for examining the effect of the sound insulating member 8 of the above embodiment will be described.

  In this experiment, in the prefabricated refrigerator configured as described above, a measurement microphone was installed in front of the air inlet 12c, and the volume of noise leaking from the air inlet 12c was measured. At this time, the measurement microphone was installed at a position 1 m away from the condenser 14. Moreover, the outside temperature at the time of this measurement was 32 degreeC. The noise source is mainly the motor of the compressor 22 and the condenser fan 16. The compressor 22 uses a horizontal scroll compressor having an output of 750 W, and the motor of the condenser fan 16 has an output of 350 W. A single-phase AC fan motor was used.

  Under these conditions, noise was measured for both the case where the sound insulating member 8 was attached to the casing 12 outside the refrigerator 10 of the cooling unit 6 and the case where the sound insulating member 8 was not attached. As a result, it was found that the noise can be reduced by about 3 dB by attaching the sound insulating member 8 to the housing 12 of the outside of the cabinet 10 as compared with the case where the sound insulating member 8 is not attached. From this result, it was found that the noise transmitted to the people around the prefabricated refrigerator can be reduced by attaching the sound insulation member 8 according to the above embodiment to the casing 12 of the outside of the cabinet 10 so as to cover the intake port 12c.

  As described above, in the present embodiment, the attachment portion 34 provided on the sound insulation wall 32 is configured to be attachable to the casing 12 of the external storage 10 of the cooling unit 6 by magnetic force. The sound insulation member 8 can be attached to the exterior 10 of the cooling unit 6 simply by contacting the outer surface of the housing 12 of the exterior 10. For this reason, even when the cooling unit 6 is installed on the top wall 2a of the refrigerator main body 2, the operator performs complicated work on the top wall 2a of the refrigerator main body 2, for example, the housing of the outside 10 of the cooling unit 6 Bolt holes are formed in the body 12, and the sound insulation member 8 is simply cooled without inserting bolts into the bolt holes and fastening the housing 12 of the sound insulation member 8 and the external housing 10 with bolts and nuts. It can be attached to the outside 10 of the unit 6. Therefore, in this embodiment, the sound insulation member 8 can be easily retrofitted to the exterior 10 of the cooling unit 6 installed on the top wall 2a of the refrigerator body 2.

  Further, in this embodiment, the sound insulating wall 32 of the sound insulating member 8 is disposed outside the air inlet 12c so as to open upward, so that the cooling unit 6 can be connected to the outside of the cooling unit 6 through the opening on the upper surface of the sound insulating wall 32. The air can be easily taken into the interior 10. Furthermore, even if noise leaks outside through the opening on the top surface of the sound insulation wall 32 due to the sound insulation wall 32 being disposed outside the intake port 12c so as to open upward, the noise passes upward, It is difficult to convey to the side of the prefabricated refrigerator, that is, the people around the prefabricated refrigerator. Therefore, in this embodiment, it is possible to reduce noise transmitted to people around the prefabricated refrigerator while facilitating the intake of air into the outside 10 of the cooling unit 6.

  Further, when the sound insulation wall is disposed outside the intake port 12c so as to open on the side surface, the flow of air flowing through the opening to the intake port 12c becomes a horizontal flow from the side of the sound insulation wall. Therefore, the sound generated by this air flow is easily transmitted to the person on the side of the prefabricated refrigerator. On the other hand, in this embodiment, since the upper surface of the sound insulation wall 32 is opened, the flow of the air flowing through the opening to the intake port 12c is a flow from the upper side to the lower side. For this reason, compared with the case where the side surface of the sound insulation wall is opened, it is possible to make it difficult for a person at the side of the prefabricated refrigerator to hear noise caused by the air flow from the opening of the sound insulation wall 32 to the intake port 12c.

  Moreover, in this embodiment, since the soundproofing material 36 is affixed to the whole inner surface of the sound insulation wall 32, the soundproofing material 36 transmits noise leaking from the air inlet 12c to people around the prefabricated refrigerator. It can be suppressed more.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes meanings equivalent to the scope of claims for patent and all modifications within the scope.

  In the said embodiment, although the example which affixed the magnet 34b of the attachment part 34 of the sound-insulation member 8 over the whole outer surface of the fixing | fixed part 34a was shown, this invention is not restricted to this structure, and an attachment part is the structure other than the above. You may provide a magnet in.

  For example, the magnet 44b may be attached to a part of the outer surface of the fixing portion 44a of the attachment portion 44 as in the first modification of the embodiment shown in FIG. In this modification, a pair of magnets 44b and 44b are attached to the fixed portion 44a with a space therebetween in the vertical direction. And it is preferable that the recessed parts 12f and 12f for fitting the magnets 44b and 44b of the said attachment part 44 in the outer surface of the side wall 12b of the housing | casing 12 of the said exterior 10 are formed. Each recess 12f is arranged at a position corresponding to each magnet 44b fitted therein, and has a depth and a shape corresponding to each magnet 44b. And when the magnets 44b and 44b are fitted into the recesses 12f and 12f, the positional displacement of the sound insulating member 8 with respect to the housing 12 of the exterior 10 is suppressed.

  Further, in the configuration of the first modified example, as shown in FIG. 4, the sealing material 50 is applied along the vertical direction at the joint portion between the end portion of the side wall portion 32 b of the sound insulating wall 32 and the outer surface of the housing 12. Has been. As this sealing material 50, a caulking material, various sealing materials, or various sealing materials other than these can be used. And the clearance gap between the edge part of the side wall part 32b of the sound insulation wall 32 and the outer surface of the housing | casing 12 of the said exterior 10 is obstruct | occluded by the sealing material 50. FIG.

  In the configuration of the first modified example, since the recesses 12f and 12f for fitting the magnets 44b and 44b of the attachment portion 44 of the sound insulating member 8 are formed on the side wall 12b of the casing 12 of the outside of the cabinet 10, After the sound insulating member 8 is attached to the side wall 12b of the housing 12 of the outside of the cabinet 10, it is possible to prevent the sound insulating member 8 from being displaced relative to the outside of the cabinet 10.

  Further, in the configuration of the first modified example, the gap between the end of the side wall portion 32b of the sound insulating wall 32 of the sound insulating member 8 and the outer surface of the housing 12 of the outside of the cabinet 10 is closed by the sealing material 50. It is possible to prevent noise from leaking outside the sound insulation member 8 through the gap. For this reason, it can suppress more that the noise which leaks from the said inlet 12c is transmitted to the person around the prefabricated refrigerator.

  Moreover, like the 2nd modification of the said embodiment shown in FIG.5 and FIG.6, it can be hooked on the protrusion part 12h of the housing | casing 12 of the exterior 10 of the cooling unit 6 instead of the magnet 34b of the said embodiment. The configured latching portion 54 may be provided on the sound insulation member 8.

  Specifically, the cooling unit 6 is connected to the left and right ends of the side wall 12b provided with the air inlet 12c of the casing 12 of the external housing 10, and is arranged perpendicular to the side wall 12b provided with the air inlet 12c. A pair of protrusions 12h and 12h are provided on the side walls 12g and 12g, respectively. The pair of projecting portions 12h and 12h project vertically from the outer surface of the side wall 12g and are arranged at intervals in the vertical direction.

  A pair of latching portions 54 and 54 are provided on the side wall portions 32b and 32b of the sound insulating wall 32 of the sound insulating member 8, respectively. Each of the latching portions 54 is latched on the corresponding projection 12h. And each latching part 54 is the outer surface of the side wall part 32b of the sound insulation wall 32 so that it may protrude in the housing | casing 12 side of the said exterior 10 from the edge part on the opposite side to the said front wall part 32a of the side wall part 32b of the sound insulation wall 32. Is attached.

A notch 54a is formed. The notch 54 a extends upward from the lower end of the portion protruding from the end of the side wall 32 b of the hook 54.

  When the hooking portion 54 is hooked on the protrusion 12h, the sound insulating member 8 is disposed above the protrusion 12h so that the notch 54a is aligned with the position of the protrusion 12h. By moving the member 8 downward, the protrusion 12h is fitted into the notch 54a of the hook 54.

  In the second modified example, the latching portion 54 provided on the sound insulation wall 32 is configured to be latchable on the protruding portion 12h of the housing 12 of the exterior 10 of the cooling unit 6, so that the latching portion 54 is The sound insulation member 8 can be attached to the exterior 10 of the cooling unit 6 simply by being hooked on the protrusion 12 h of the housing 12 of the exterior 10. For this reason, even when the cooling unit 6 is installed on the top wall 2a of the refrigerator main body 2, the operator performs complicated work on the top wall 2a of the refrigerator main body 2, for example, the housing of the outside 10 of the cooling unit 6 Bolt holes are formed in the body 12, and the sound insulation member 8 is simply cooled without inserting bolts into the bolt holes and fastening the housing 12 of the sound insulation member 8 and the external housing 10 with bolts and nuts. It can be attached to the outside 10 of the unit 6. Therefore, also in this 2nd modification, the sound insulation member 8 can be easily retrofitted with respect to the cooling unit 6 installed in the top wall part 2a of the refrigerator main body 2 similarly to the said embodiment.

  In addition, in this 2nd modification, although the structure which latches the latching | locking part 54 of the sound-insulation member 8 to the projection part 12h of the housing | casing 12 of the housing | casing exterior 10 of the cooling unit 6 was shown, the housing | casing of the said housing | casing exterior 10 is shown. Any configuration other than the above may be used as long as the latching portion of the sound insulating member 8 can be latched at the 12 predetermined locations. That is, the structure, position or number of the latching portions, the structure of the portion where the latching portion is latched in the outside of the cooling unit are not limited to those described above, and various configurations can be applied. is there. As an example, for example, the hook 54 is changed to be pivotally supported on the side wall 32b of the sound insulation wall 32, and the sound insulation member 8 is placed at an appropriate position on the top wall 2a of the refrigerator body 2. You may make it latch the said latching | protrusion part 12h by rotating the latching | locking part 54 around an axis | shaft.

  Moreover, in the said embodiment, although it was set as the structure installed so that the sound-insulation wall 32 may open above the said inlet 12c upwards, this invention is not limited to this structure. For example, a configuration in which the upper surface of the sound insulating wall 32 is closed by a sheet metal and a part of the side wall portion 32b is opened may be employed.
