[0008] (Findings that formed the basis of this disclosure) At the time when the inventors arrived at the idea of ​​the present disclosure, there was a technique for installing a compressor on the bottom plate of a housing in an outdoor unit using a refrigeration cycle. Generally, the noise generated when the compressor is operated is a problem, so the noise of the compressor is reduced by wrapping a soundproof sheet around the outer periphery of the compressor. However, with conventional technology, when cooled refrigerant flows through refrigerant piping located above the compressor, condensation occurs in the refrigerant piping, and this condensed water can drip onto the top of the compressor or onto the bottom plate supporting the compressor. In this case, it was discovered that if condensation water dripping onto the compressor penetrates the soundproofing sheet, or if condensation water dripping onto the bottom plate is sucked up from below the soundproofing sheet, this could lead to deterioration of the soundproofing sheet and could even result in damage to the soundproofing sheet.In order to solve this problem, the subject matter of the present disclosure has been formed. The present disclosure provides a cover member for a compressor that can suppress the penetration of condensation water into a soundproof sheet of a compressor and suppress deterioration of the soundproof sheet.

[0009] Hereinafter, embodiments will be described in detail with reference to the drawings. However, unnecessary detailed description may be omitted. For example, detailed description of well-known matters or redundant description of substantially the same configuration may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0010] (Embodiment 1) Hereinafter, the first embodiment will be described with reference to the drawings. [1-1.Configuration] [1-1-1. Configuration of the heat medium circulator] FIG. 1 is a refrigeration circuit diagram showing a heat medium circulating device 1 according to the first embodiment. In this embodiment, the heat medium circulating device 1 is an outdoor unit of a heat pump type hot water heater. The hot water heater is a device that heats a room by circulating a heat medium (for example, water) heated by a refrigeration cycle of the heat medium circulating device 1 through a heat exchanger of an indoor unit. The hot water heater of this embodiment can also perform cooling operation by circulating a heat medium cooled by a refrigeration cycle through the indoor unit. In FIG. 1, the flow of the refrigerant and heat medium during cooling operation of the hot water heater is indicated by arrows.

[0011] The heat medium circulating device 1 is provided with a compressor 2. The compressor 2 is a device that draws in, compresses, and discharges a refrigerant. In the heat medium circulating device 1, a flow path switching mechanism 3 is connected to the discharge side and the suction side of the compressor 2. The flow path switching mechanism 3 switches the destination of the refrigerant discharged to the compressor 2 between an air heat exchanger 4 serving as a heat source side heat exchanger and a water heat exchanger 10 serving as a user side heat exchanger, and causes the destination heat exchangers 4, 10 to function as condensers. The flow path switching mechanism 3 also draws the refrigerant that has passed through the evaporator of one of the heat exchangers 4, 10 into the compressor 2. The flow path switching mechanism 3 is, for example, a four-way valve.

[0012] The air heat exchanger 4 is a heat exchanger that exchanges heat between the refrigerant inside and the outside air. The air heat exchanger 4 is, for example, a fin-tube type heat exchanger. The heat medium circulating device 1 is provided with a blower 5 that flows the outside air through the air heat exchanger 4. In this embodiment, the blower 5 is an axial flow fan.

[0013] The water heat exchanger 10 is a plate-type heat exchanger that exchanges heat between a refrigerant flowing inside and a heat medium. The heat medium heated or cooled by the water heat exchanger 10 circulates between the heat medium circulator 1 and the indoor unit to air-condition the room.

[0014] The air heat exchanger 4 and the water heat exchanger 10 are connected via an expansion valve 6. A receiver tank 15 that stores low-temperature, high-pressure liquid-phase refrigerant cooled by the condenser is provided between the water heat exchanger 10 and the expansion valve 6 (see FIG. 2). The expansion valve 6 is a valve that reduces the pressure of the refrigerant that flows from the condenser of each heat exchanger 4, 10 via the receiver tank 15 to make it a two-phase gas-liquid refrigerant, and allows it to flow into the evaporator of each heat exchanger 4, 10. In this embodiment, the opening of the expansion valve 6 can be adjusted by electronic control, and the flow rate of the refrigerant is adjusted by changing the opening.

[0015] On the inlet side of the water heat exchanger 10, a circulation pump 16 and a valve 16a that can be connected to an external water pipe are provided. A gas-liquid separator 17 that removes refrigerant or air from the heat medium is provided downstream of the water heat exchanger 10. A valve 18a that can be connected to a water pipe external to the heat medium circulating device 1 via an outlet-side water pipe 18 is provided on the outlet-side water pipe 18. In addition, a flow rate sensor 19 that measures the flow rate of the heat medium is provided on the outlet-side water pipe 18.

[0016] [1-1-2. Configuration of the heat medium circulator] 2 is a perspective view showing the inside of the heat medium circulating device according to Embodiment 1. In the drawing, the symbol X indicates the left side of the heat medium circulating device 1, the symbol Y indicates the front side of the heat medium circulating device 1, and the symbol Z indicates the upper side. Fig. 3 is a perspective view showing a part of the heat medium circulating device according to Embodiment 1. Fig. 4 is a plan view showing a compressor portion of the heat medium circulating device according to Embodiment 1. 2, the heat medium circulator 1 is provided with a blower chamber 7, which is a space partitioned off to the left by a partition plate 9, and a machine chamber 8, which is a space partitioned off to the right by the partition plate 9. The partition plate 9 is made of sheet metal and is disposed in an orientation that is approximately perpendicular to the left-right direction.

[0017] The blower chamber 7 is provided with an air heat exchanger 4 and a blower 5. The air heat exchanger 4 is provided on the right side and rear side of the blower chamber 7. The blower 5 blows air inside the heat medium circulating device 1 forward, thereby drawing in outside air through the air heat exchanger 4 and exchanging heat between the outside air and the refrigerant inside the air heat exchanger 4. In this embodiment, a heat medium circulating device 1 in which two blowers 5 are provided vertically in the blower chamber 7 will be described as an example, but the number of blowers 5 of the heat medium circulating device 1 is not particularly limited.

[0018] The machine room 8 is provided with the compressor 2, the flow path switching mechanism 3, the expansion valve 6, the receiver tank 15, the water heat exchanger 10, and the gas-liquid separator 17. The compressor 2 is placed on the bottom plate 1a of the heat medium circulator 1 via rubber legs. The flow path switching mechanism 3 is disposed above the compressor 2. The water heat exchanger 10 is provided at a position spaced above the bottom plate 1a via a support member 8a made of sheet metal.

[0019] 3 and 4, a refrigerant return pipe 2a and an injection pipe 2b are connected to the top surface of the compressor 2. A refrigerant discharge pipe 2c is provided on the side surface of the compressor 2, and is connected to the side surface of the compressor 2 and routed along the outer circumferential surface of the compressor 2. A terminal portion (not shown) protruding in a substantially rectangular shape is provided on the side surface of the compressor 2. Inside the terminal portion, connection terminals (not shown) for connecting, for example, power supply wiring, signal wiring, etc. to the compressor 2 are provided.

[0020] A soundproof sheet 30 is wrapped around the outer circumferential surface of the compressor 2. The soundproof sheet 30 is made of, for example, a material in which fibers are bonded to one side of a rubber sheet. The length of the soundproof sheet 30 is longer than the outer periphery of the compressor 2. Square cutouts 31 are formed on both ends of the soundproof sheet 30. The soundproof sheet 30 is wrapped around the outer peripheral surface of the compressor 2 and overlapped with the notch 31 positioned at the terminal portion. In this state, the soundproof sheet 30 is fixed to the outer peripheral surface of the compressor 2 by holding down both ends of the soundproof sheet 30 with holding members 32 such as tape.

[0021] In addition, the terminal portion is provided with a soundproofing member 33 that covers the terminal portion. As shown in FIGS. 3 and 4, the soundproofing member 33 is formed in a box shape so as to cover the terminal portion.

[0022] [1-1-3. Configuration of cover member] A cover member 40 is provided on the top of the compressor 2. FIG. 5 is a development view showing the cover member according to the first embodiment. As shown in FIG. 5, the cover member 40 includes a main body 41 in the form of a flat plate having a substantially rectangular shape. The main body 41 is formed with a notch 42 extending from the outer edge toward the center of the main body 41. The notch 42 is formed in a tapered shape with a width that decreases toward the center.

[0023] A substantially circular hole 43a is formed at the inner end of the notch 42. A refrigerant return pipe 2a connected to the compressor 2 is inserted into this hole 43a. In addition, the main body 41 is formed with a hole 43b through which the injection pipe 2b connected to the compressor 2 is inserted, a hole 43c through which the refrigerant discharge pipe 2c is inserted, and a hole 43d through which the sensor wiring (not shown) is inserted.

[0024] A slit 44 is formed between the hole 43a through which the refrigerant return pipe 2a is inserted and the hole 43b through which the injection pipe 2b is inserted. In addition, slits 44 are formed between the outer edge of the main body 41 and the hole 43c through which the refrigerant discharge pipe 2c is inserted, and between the outer edge of the main body 41 and the hole 43d through which the sensor wiring is inserted.

[0025] The main body 41 has a hook-and-loop fastener 45 attached to one side edge of the notch 42, extending from the outer edge toward the center of the main body 41. In addition, two hook-and-loop fasteners 46, 46 are attached to the other side edge of the notch 42 so as to protrude from the other side edge. Then, by overlapping both side edges of the notch 42 and adhering the hook-and-loop fasteners 45 and 46 together in this state, the main body 41 can be held in a substantially umbrella shape. In this embodiment, the outer shape of the main body 41 is formed to be larger than the outer shape of the soundproof sheet 30 when the main body 41 is attached to the compressor 2 .

[0026] [1-2. Effect] Next, the operation of the first embodiment will be described. First, the cover member 40 is placed over the compressor 2, and the notch 42 is inserted into the refrigerant return pipe 2a from the rear of the compressor 2, so that the refrigerant return pipe 2a is positioned in the hole 43a. Subsequently, the injection pipe 2b, the refrigerant discharge pipe 2c, and the sensor wiring are positioned in the holes 43b, 43c, and 43d via the slit 44, respectively. Then, both side edges of the notch 42 are overlapped, and in this state, the hook-and-loop fasteners 45, 46 are attached to each other, thereby fixing the main body 41 to the top of the compressor 2 while maintaining the approximate umbrella shape.

[0027] By configuring in this manner, even if condensation occurs on the refrigerant piping located above the compressor 2 and the condensed water drips above the compressor 2, the cover member 40 can prevent the condensed water from dripping directly onto the compressor 2. Furthermore, since the cover member 40 is formed in an umbrella shape, condensed water that drips onto the cover member 40 falls downward from the outer edge of the main body 41. Furthermore, because the outer shape of the main body 41 constituting the cover member 40 is formed larger than the outer shape of the soundproof sheet 30, condensation water that falls from the outer edge of the cover member 40 falls onto the bottom plate without dripping onto the soundproof sheet 30. Therefore, since the condensation water falls outside the periphery of the compressor 2, it is possible to prevent the condensation water from being sucked up from below the soundproof sheet 30.

[0028] During cooling operation, the heat medium circulator drives the compressor 2, and as shown in Fig. 1, the flow path switching mechanism 3 causes the refrigerant discharged from the compressor 2 to flow through the air heat exchanger 4 to dissipate heat. The refrigerant that has dissipated heat in the air heat exchanger 4 is liquefied, passes through the expansion valve 6, and becomes a gas-liquid two-phase refrigerant before flowing into the water heat exchanger 10. The refrigerant in a gas-liquid two-phase state that has flowed into the water heat exchanger 10 absorbs heat from the heat medium flowing through the water heat exchanger 10 and evaporates, becoming a gas refrigerant and returning to the compressor 2. On the other hand, the heat medium that has undergone heat exchange in the water heat exchanger 10 is circulated between the indoor unit and the water heat exchanger 10 while cooling the water by driving the circulation pump 16, thereby cooling the room.

[0029] In this case, the compressor 2 is covered with the soundproof sheet 30 and the soundproof member 33, so that the noise generated by the compressor 2 is absorbed by the fibers that make up the soundproof member 33, thereby suppressing the noise of the compressor 2.

[0030] [1-3. Effects, etc.] As described above, the cover member 40 of this embodiment has a substantially planar main body 41, and the main body 41 has hole portions 43a, 43b, 43c through which the pipes 2a, 2b, 2c connected to the compressor 2 are inserted. Thus, by providing the cover member 40 on the upper surface of the compressor 2, the cover member 40 can prevent condensation water dripping from the refrigerant piping located above the compressor 2 from directly hitting the compressor 2. This can prevent condensation water from penetrating the soundproof sheet 30 arranged around the compressor 2, and can prevent deterioration of the soundproof sheet 30. Furthermore, by providing holes 43a, 43b, and 43c in the main body 41, through which the pipes 2a, 2b, and 2c connected to the compressor 2 are inserted, the cover member 40 can be supported by the pipes 2a, 2b, and 2c. This makes it possible to prevent the cover member 40 from shifting position, and to hold the cover member 40 in a predetermined position.

[0031] In addition, in the cover member 40 of this embodiment, a notch 42 is formed in the main body 41, extending from the outer edge of the main body 41 toward the center, and the main body 41 is maintained in an approximately umbrella shape by overlapping and fixing both side edges of the notch 42. This allows the cover member 40 to be maintained in a generally umbrella shape, so that when condensation water from the refrigerant piping located above the compressor 2 drips onto the cover member 40, the condensation water can be quickly dripped from the outer edge of the main body 41. This prevents the condensation water from penetrating the soundproof sheet 30 arranged around the compressor 2, and prevents deterioration of the soundproof sheet 30.

[0032] In addition, in the cover member 40 of this embodiment, slits 44 are formed in the main body 41, which continue from the outer edge or notch 42 of the main body 41 to the hole portions 43a, 43b, 43c, and 43d, and the hole portions 43a, 43b, 43c, and 43d allow the pipes 2a, 2b, and 2c to be inserted through the slits 44. Thus, by providing the slits 44, the pipes 2a, 2b, and 2c can be easily inserted into the holes 43a, 43b, 43c, and 43d of the main body 41.

[0033] Furthermore, in the cover member 40 of this embodiment, the main body 41 has an outer shape larger than the outer shape of the soundproofing member attached to the outer peripheral surface of the compressor 2 . As a result, by forming the outer shape of the main body 41 larger than the outer shape of the soundproof sheet 30, condensation water that falls from the outer edge of the cover member 40 can fall onto the bottom plate without dripping onto the soundproof sheet 30. Therefore, since the condensation water falls outside the periphery of the compressor 2, it is possible to prevent the condensation water from being sucked up from below the soundproof sheet 30.

[0034] (Other embodiments) As described above, the first embodiment has been described as an example of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. Furthermore, it is also possible to combine the components described in the first embodiment above to create new embodiments.

[0035] (Addendum) The above description of the embodiments discloses the following techniques. (Technology 1) A cover member for a compressor, which is a waterproof member that covers the top surface of a compressor and has a substantially planar main body, the main body having a hole portion through which a pipe connected to the compressor can be inserted. According to this configuration, by providing a cover member on the top surface of the compressor, the cover member can prevent condensation water dripping from the refrigerant pipe located above the compressor from directly hitting the compressor, thereby preventing condensation water from penetrating into the soundproofing sheet arranged around the compressor and suppressing deterioration of the soundproofing sheet. Furthermore, by providing a hole in the main body through which the piping connected to the compressor can be inserted, the cover member can be supported by the piping, which prevents the cover member from shifting out of position and allows the cover member to be held in a predetermined position.

[0036] (Technology 2) A cover member for a compressor according to Technology 1, in which a notch is formed in the main body from the outer edge of the main body toward the center, and the main body is maintained in a roughly umbrella shape by overlapping and fixing both side edges of the notch. With this configuration, the cover member can be maintained in a generally umbrella shape, so that when condensation water from the refrigerant pipe located above the compressor drips onto the cover member, the condensation water can be quickly drained from the outer edge of the main body, preventing the condensation water from penetrating the soundproof sheet disposed around the compressor and preventing deterioration of the soundproof sheet.

[0037] (Technology 3) A cover member for a compressor according to Technology 1 or Technology 2, wherein a slit is formed in the main body, the slit continuing from the outer edge of the main body or the notch to the hole portion, and the hole portion allows the piping to be inserted through the slit. According to this configuration, the provision of the slit allows the piping to be easily inserted into the hole in the main body.

[0038] (Technology 4) The cover member for a compressor according to any one of Technology 1 to Technology 3, wherein the main body has an outer shape larger than an outer shape of a soundproofing member attached to the outer peripheral surface of the compressor. With this configuration, by making the outer shape of the main body larger than that of the soundproof sheet, condensation water that falls from the outer edge of the cover member can fall onto the bottom plate without dripping onto the soundproof sheet. Therefore, since the condensation water falls outside the periphery of the compressor, it is possible to prevent the condensation water from being sucked up from below the soundproof sheet. [Industrial Applicability]

[0039] The present disclosure can be suitably used as a cover member for a compressor that can suppress the penetration of condensation water into the soundproof sheet of the compressor and suppress deterioration of the soundproof sheet. [Explanation of symbols]
