Description

  The present invention relates to an outdoor unit applied to a refrigeration apparatus such as an air conditioner.

  DESCRIPTION OF RELATED ART Conventionally, the refrigerating apparatus provided with the refrigerant circuit, such as an air conditioner, a refrigerator, a refrigerator, and a heat pump water heater, is known. The outdoor unit of the refrigeration apparatus includes a compressor, a soundproof material that covers the compressor in order to reduce noise generated during operation of the compressor, and a case that houses these. The soundproofing material has a sheet-like structure in which a soundproofing material made of a material with excellent sound insulation properties, such as rubber, and a sound absorbing material made of a material with excellent sound absorption properties are laminated. It is fixed to the said compressor in the state wound around the machine (for example, refer patent document 1).

  As the material of the sound absorbing material, a material in which a continuous void is formed, for example, felt is used. When sound waves are incident on the sound absorbing material, the air present in the gap vibrates, and the vibration of the air is converted into thermal energy by the friction of the fibers, resulting in a sound absorbing phenomenon.

JP 2009-8363 A

  The soundproofing material is wound around the compressor so that both ends thereof are appropriately overlapped, and the both ends are fixed to each other in this state, and the soundproofing material is attached to the compressor. As the fixing means, since workability is good, a fixing means such as a culture hook or a hook-and-loop fastener capable of fixing both ends while having a degree of freedom in winding amount is provided. For this reason, the actual winding amount varies depending on the operator, and the soundproofing material may be strongly wound around the compressor more than necessary. In such a case, the sound-absorbing material may be compressed and the internal gaps may be crushed, resulting in a case where the sound-absorbing performance planned in design cannot be enjoyed.

  This invention is made in view of such a situation, and in the outdoor unit provided with the soundproofing material which covers the side surface of a compressor, preventing the fall of the sound absorption performance by the individual difference of the winding work of a soundproofing material is prevented. It aims at suppressing.

  In order to solve the above-described problems, an outdoor unit of the present invention includes a compressor that compresses a refrigerant in a refrigerant circuit, and a soundproofing material that covers a side surface of the compressor, and the soundproofing material is sound-absorbing laminated on each other. A soundproof material main body that is wound around the compressor with the sound absorbing material inside, and a winding terminal end that is one end of the soundproofing material main body is beyond the winding start end that is the other end The soundproofing material main body is wound around the compressor so that the soundproofing material main body is wound around the compressor, and a fixing means for maintaining the wound state of the soundproofing material main body, and the soundproofing material main body wound around the compressor by the fixing means And positioning means for determining a relative position of the winding end portion with respect to the winding start end portion in the winding direction of the soundproof material main body when fixing.

  In this configuration, the soundproofing material is attached to the compressor by holding the wound state by the fixing means in a state where the soundproofing material main body is wound around the compressor. Since the soundproofing material is provided with positioning means for determining the position of the winding end portion with respect to the winding start end portion, when attaching the soundproofing material to the compressor, the soundproofing material is not affected by the operator and is fixed. It is possible to wind the soundproof material around the compressor by the amount of winding, and as a result, the soundproof material is prevented from being strongly wound around the compressor due to individual differences.

  Such a configuration is particularly useful when the sound absorbing material is a glass fiber sound absorbing material. That is, while the sound absorbing material made of glass fiber has high sound absorbing performance, the compression rate is large and the internal voids are easily crushed compared to other sound absorbing materials. For this reason, it is conceivable that when strongly pressed, the state in which the internal gap is crushed is maintained, and the sound absorption performance is significantly reduced. Therefore, if the above configuration is applied to a compressor in which a soundproofing material including such a sound absorbing material made of glass fiber is attached to the compressor, it is possible to effectively suppress a decrease in sound absorbing performance.

  It is preferable that the positioning means can position both upper and lower ends of the winding end portion.

  According to this configuration, it is possible to prevent a difference in winding amount of the soundproof material between the top and bottom of the compressor, and to prevent the soundproof material from being wound obliquely around the compressor. Therefore, it is possible to prevent a decrease in soundproofing effect due to these winding defects.

  The soundproof material body has a shape that can be wound around a plurality of types of compressors having different diameters as the compressor, and the soundproofing material includes a plurality of the soundproofing materials corresponding to each type of the compressor. It may be provided with positioning means.

  In this configuration, the soundproofing material is made common to a plurality of types of compressors. In particular, since the positioning means corresponding to each type of compressor is provided, it is possible to appropriately wind the soundproof material with a predetermined predetermined winding amount to any compressor.

  The positioning means only needs to be able to determine the relative position of the winding end portion with respect to the winding start end portion of the soundproof material body. For example, the positioning means includes a mark formed on the sound insulating material. can do.

  According to this configuration, the positioning means is realized with a simple configuration. In other words, by aligning the position of the winding end of the soundproofing material main body with the mark and holding the winding state of the soundproofing material main body with the fixing means in this state, the soundproofing material (soundproofing material main body) is appropriately wound with a certain amount of winding. It becomes possible. In this case, as a mark, a character, a line, a notch, a hole, etc. can be illustrated.

  Further, the positioning means may be a convex portion that protrudes from the surface of the sound insulating material and has a shape capable of abutting the winding end portion of the soundproofing material main body.

  According to this configuration, the winding end portion of the soundproof material main body is abutted against the convex portion for positioning, so positioning accuracy is high, and the winding end portion can be intuitively positioned by the abutment. It will be good.

  Further, the positioning means comprises a step portion formed on the sound insulating material by cutting out the sound insulating material in the thickness direction in a certain region including the winding start end portion of the sound insulating material main body. The portion may have a shape capable of abutting the winding end portion.

  According to this configuration, the thickness of the overlapping portion of the winding start end portion and the termination portion is expanded in the overlapping direction while enabling the winding end portion of the soundproof material main body to be positioned against the sound insulating material. It is possible to suppress this.

  Further, the positioning means is such that the soundproof material body is formed such that the end of the sound insulating material on the winding end portion side protrudes in the winding direction from the end of the sound absorbing material, Of these, the winding end portion may be positioned by abutting the end portion on the winding end portion side against the winding start end portion.

  Also in this configuration, positioning can be performed while suppressing an increase in the thickness of the overlapping portion between the winding start end portion and the terminal end portion in the overlapping direction.

  As described above, according to the present invention, it is possible to make the winding amount of the soundproofing material attached to the compressor constant without being influenced by the operator. It is prevented that the wire is strongly wound around. Therefore, it is possible to suppress a decrease in sound absorption performance due to individual differences in the work of winding the soundproof material.

  Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a piping diagram showing an air conditioner to which the present invention is applied. The air conditioner 1 shown in this figure includes an outdoor unit 10 installed outdoors and an indoor unit 12 set indoors, and performs cooling operation and heating operation while circulating a refrigerant between them. Do.

  The outdoor unit 10 includes a compressor 22, an accumulator 24, a four-way switching valve 26, an outdoor heat exchanger 28, an expansion valve 30, and a casing 11 in which the compressor 22 and the like are accommodated. On the other hand, the indoor unit 12 includes an indoor heat exchanger 32 and a casing 13 in which the indoor heat exchanger 32 is accommodated.

  The compressor 22, the accumulator 24, the four-way switching valve 26, the outdoor heat exchanger 28, the expansion valve 30 and the indoor heat exchanger 32 are connected by piping, thereby enabling the refrigeration cycle to be performed while circulating the refrigerant. A refrigerant circuit 20 is configured.

  More specifically, the compressor 22 includes a refrigerant suction port and a discharge port. The discharge port is connected to the first port 27a of the four-way switching valve 26 via the discharge pipe 2a, and the suction port is connected to the third port 27c of the four-way switching valve 26 via the suction pipe 2b. Thus, the compressor 22 sucks and compresses the refrigerant through the suction pipe 2b and discharges the compressed refrigerant to the discharge pipe 2a. As this compressor 22, for example, a hermetic high-pressure dome type scroll compressor or a swing compressor is applied.

  The accumulator 24 is interposed in the middle of the suction pipe 2b, and separates the liquid component from the refrigerant sucked into the compressor 22. The accumulator 24 is integrally assembled to the compressor 22 by being fixed to an attachment portion formed on the compressor 22 (see FIG. 3). The compressor 22 is provided with a soundproofing member 3 as a soundproofing measure. The soundproof member 3 will be described in detail later.

  The outdoor heat exchanger 28 includes two input / output ports. The input / output port on one side is connected to the second port 27b of the four-way switching valve 26 via the gas pipe 2c, and the input / output port on the other side is connected to the expansion valve 30 via the liquid pipe 2d. An outdoor fan 29 is attached to the outdoor heat exchanger 28, and the outdoor heat exchanger 28 exchanges heat between the refrigerant introduced from the input / output port and the outdoor air taken in by the outdoor fan 29. Similar to the outdoor heat exchanger 28, the indoor heat exchanger 32 also includes two input / output ports. The input / output port on one side is connected to the fourth port 27d of the four-way switching valve 26 via the gas pipe 2e, and the input / output port on the other side is connected to the expansion valve 30 via the liquid pipe 2f. The indoor heat exchanger 32 is provided with an indoor fan 33, and the indoor heat exchanger 32 exchanges heat between the refrigerant introduced from the input / output port and the indoor air taken in by the indoor fan 33. As the outdoor heat exchanger 28 and the indoor heat exchanger 32, for example, a cross fin type fin-and-tube heat exchanger is applied.

  The expansion valve 30 expands the refrigerant flowing from the outdoor heat exchanger 28 through the liquid pipe 2d or from the indoor heat exchanger 32 through the liquid pipe 2f, thereby reducing the refrigerant to a predetermined pressure. As the expansion valve 30, for example, an electronic expansion valve with a variable opening is applied.

  The four-way switching valve 26 includes a first state (state indicated by a solid line in FIG. 1) in which the first port 27a and the second port 27b communicate with each other and the third port 27c and the fourth port 27d communicate with each other. 27a and the fourth port 27d communicate with each other and the second port 27b and the third port 27c communicate with each other (a state indicated by a broken line in FIG. 1). Switching control is performed.

  By configuring the refrigerant circuit 20 as described above, during the cooling operation, the four-way switching valve 26 is controlled to the first state, whereby the refrigerant circulates in the direction indicated by the solid line arrow in FIG. The outdoor heat exchanger 28 functions as a condenser (heat radiator), and the indoor heat exchanger 32 functions as an evaporator. That is, in the cooling operation, the high-temperature and high-pressure refrigerant discharged from the compressor 22 flows to the outdoor heat exchanger 28 and condenses by releasing heat to the outdoor air. The condensed refrigerant is depressurized by the expansion valve 30 and then flows to the indoor heat exchanger 32 where it absorbs heat from the indoor air and evaporates. Then, the evaporated refrigerant is sucked into the compressor 22 through the accumulator 24.

  On the other hand, during the heating operation, the four-way switching valve 26 is controlled to the second state, whereby the refrigerant circulates in the direction indicated by the broken line arrow in FIG. 1, and as a result, the outdoor heat exchanger 28 serves as the evaporator and the indoor heat The exchanger 32 functions as a condenser (heat radiator). That is, in the heating operation, the high-temperature and high-pressure refrigerant discharged from the compressor 22 flows into the indoor heat exchanger 32 and condenses by releasing heat to the indoor air. The condensed refrigerant is decompressed by the expansion valve 30, and then flows to the outdoor heat exchanger 28, absorbs heat from the outdoor air, and evaporates. Then, the evaporated refrigerant is sucked into the compressor 22 through the accumulator 24.

  Next, the compressor 22 and the soundproof member 3 attached thereto will be described with reference to FIGS.

  The compressor 22 includes a substantially columnar vertically long main body portion 22 a and a plurality of leg portions 22 b connected to the lower end portion thereof, and is placed on the bottom plate 16 of the casing 11 and the outdoor unit 10. Is housed inside. The accumulator 24 has a substantially cylindrical shape with a smaller diameter and a shorter dimension than the main body portion 22a of the compressor 22, and is fixed to a side surface portion of the main body portion 22a.

  As described above, the soundproofing member 3 is attached to the compressor 22 as a soundproofing measure. The soundproofing member 3 includes a first soundproofing material 3A (corresponding to the soundproofing material according to the present invention) that integrally covers the side surfaces of the compressor 22 and the accumulator 24, and a second soundproofing material that covers the top surfaces of the compressor 22 and the accumulator 24. 3B.

  The first soundproofing material 3A keeps the soundproofing material main body 40 in the form of a rectangular sheet and the soundproofing material main body 40 wound around the compressor 22 and the accumulator 24 (hereinafter abbreviated as the compressor 22 etc.) in the wound state. Positioning device 45 (corresponding to the fixing means of the present invention) and positioning for determining the relative position of the winding end portion E with respect to the winding start end portion S, which will be described later, when the soundproof material body 40 is wound around the compressor 22 Means.

  The soundproof material body 40 has one end in the winding direction as a winding start end S and the other end as a winding end E, and is wound around the compressor 22 in a state where the winding end E is overlapped with the winding start end S. Therefore, the length dimension in the winding direction is set. Moreover, about the up-down direction (direction orthogonal to a winding direction), it has the length dimension which can cover the said compressor 22 whole. Specifically, the length that can cover from the lower end of the leg portion 22b of the compressor 22 to the upper end of the main body portion 22a in a state where the lower end portion of the soundproof material main body 40 is in contact with the upper surface of the bottom plate 16. It has a size.

  The soundproof material body 40 has a structure in which a sound absorbing material 41 and a sound insulating material 42 are laminated and bonded in the thickness direction, and as shown in FIGS. 2 and 3, the sound absorbing material 41 is provided on the side surface of the compressor 22 and the like. Are wound around the compressor 22 or the like with the sound absorbing material 41 facing inward so that the lower end portion contacts the upper surface of the bottom plate 16. Specifically, the soundproof material main body 40 is wound around the compressor 22 or the like so that the winding end portion E overlaps the winding start end portion S and overlaps from the outside. And in the state in which the soundproofing material main body 40 is wound around the compressor 22 or the like in this way, both ends of the soundproofing material main body 40 are fastened by the fixture 45, so that the first soundproofing material 3A is attached to the compressor 22 or the like. It is attached.

  The first soundproofing material 3 </ b> A includes a culture kite as the fixture 45. The culture bag is composed of a disk-like locking button 45a that is fixed to the sound insulating material 42 in the vicinity of the winding start end S of the soundproof material body 40, and a locking string 45b that is provided in the vicinity of the winding terminal end E. As shown in FIG. 5, the both ends of the soundproofing material main body 40 are connected to each other by the locking string 45b being wound around the locking button 45a. In the present embodiment, the locking button 45 a and the locking string 45 b are provided at positions near the upper and lower ends of the soundproof material body 40, respectively.

  The sound absorbing material 41 of the soundproofing material main body 40 is made of a fibrous sound absorbing material having a large number of continuous voids therein, and in this embodiment is made of glass fiber in which glass fibers of approximately 0.4 to 3.5 μm are intertwined. The sheet-like sound absorbing material is applied. On the other hand, as the sound insulating material 42, a material having a sound insulating property, in this embodiment, a sheet-like sound insulating material formed of rubber is applied.

  Here, a mark 46 as the positioning means is provided on the outer surface of the soundproof material main body 40, that is, the outer surface of the sound insulating material 42 in a state of being wound around the compressor 22. This mark 46 is for determining the relative position of the winding end portion E with respect to the winding start end S when the soundproof material main body 40 is wound around the compressor 22 or the like, in other words, the amount of winding of the soundproof material main body 40 around the compressor 22. It is for deciding. In the present embodiment, as shown in FIG. 4, a plurality of marks 46 corresponding to the types of the compressors 22 are provided in the vicinity of the winding start end S of the soundproof material main body 40 and at the upper and lower ends of the soundproof material main body 40, respectively. Marks 46a to 46c are provided. That is, the size of the soundproofing material body 40 is set so that the soundproofing material body 40 can be wound around a plurality of types of compressors 22 having different diameters (the diameter of the accumulator 24 is constant). A plurality of marks 46 a to 46 c indicating the position of the winding terminal end E determined for each type (diameter) of the compressor 22 are provided on the outer surface of 40.

  Each of the marks 46a to 46c includes a diameter dimension display (φ90, φ100, φ120) of the compressor 22 and a line for aligning the winding end E. As shown in FIG. 5, the first soundproofing material 3 </ b> A includes a compressor such that the winding end portion E is positioned at marks 46 a to 46 c (lines) corresponding to the type (diameter) of the compressor 22 among the marks 46 a to 46 c. In this state, both ends of the soundproofing material main body 40 are fastened by the fixture 45, so that the sounding material body 40 is wound around the compressor 22 with an appropriate winding amount according to the type (diameter) of the compressor 22. ing. In the present embodiment, the compressor 22 is φ100 (mm), and therefore the first soundproofing material 3A is positioned at the mark 46b including the diameter dimension indication of φ100 as shown in FIG. It is wound around the compressor 22 in a state.

  In addition, since the soundproof material main body 40 includes the sound absorbing material 41 made of glass fiber, the sound absorbing material 41 is compressed between the sound insulating material 42 and the compressor 22 when it is wound around the compressor 22 more strongly than necessary. In some cases, the internal voids collapse. Accordingly, the mark 46 (46a to 46c) is, for example, so that the soundproof material main body 40 contacts the side surface of the compressor 22 (main body portion 22a) in a state where the thickness of the sound absorbing material 41 before being wound is substantially maintained. Their positions are defined.

  On the other hand, the second soundproof material 3B has a shape that can integrally cover the upper surface of the compressor 22 or the like, for example, an egg-shaped sheet. As shown in FIG. 2, the second sound insulating material 3B also has a structure in which a sound absorbing material 43 and a sound insulating material 44 are laminated and bonded together in the thickness direction. The sound absorbing material 43 and the sound insulating material 44 are each made of the same material as that of the first sound insulating material 3A. Specifically, the sound absorbing material 43 is made of a sheet-like sound absorbing material made of glass fiber, and the sound insulating material 44 is rubber. It is made of a sheet-like sound insulating material formed from

  The second soundproofing material 3B is placed on the upper surface of the compressor 22 and the like so that the sound absorbing material 43 is positioned on the lower side (the side of the compressor 22 and the like). As shown in FIG. 3 and FIG. 3, the second soundproof material 3B includes a pair of through holes 50 and 52 penetrating in the thickness direction, and the through holes 50 and 52 and the periphery of the second soundproof material 3B. Slit-like cut portions 51 and 53 are provided, and the discharge pipe 2a and the suction pipe 2b are inserted into the through holes 50 and 52 through the cut portions 51 and 53, respectively, on the upper surface of the compressor 22 and the like. It is covered.

  Thus, in the outdoor unit 10 of the air conditioning apparatus 1, the soundproof member 3 is attached to the compressor 22 or the like, so that the side surface of the compressor 22 or the like is covered with the first soundproof material 3A, and the compressor 22 or the like. Is covered with the second soundproofing material 3B, and the soundproofing effect of the compressor 22 is exhibited by the sound insulation and sound absorption functions of the soundproofing materials 3A and 3B.

  In this case, the first soundproofing material 3A is attached to the compressor 22 and the like while being wound around the compressor 22 and the like. According to the first soundproofing material 3A, the mark 46 is provided on the soundproofing material main body 40. Then, the winding end portion E of the soundproof material main body 40 is positioned at the mark 46, so that it is wound around the compressor 22 with a constant winding amount. That is, it is difficult to involve individual differences in the winding work of the first soundproof material 3A. Therefore, the first soundproofing material 3A is more strongly wound around the compressor 22 and the like than necessary, and the internal gap is crushed. As a result, it is effectively suppressed that the sound absorption performance is lowered. That is, in the first soundproofing material 3A, the sound absorbing material 41 is made of a glass fiber sound absorbing material as described above, and such a glass fiber sound absorbing material has many continuous ultrafine voids inside. While exhibiting a high sound absorption effect, the compression ratio is about 1/8 to 1/10, and the compression ratio is large compared to other soundproofing materials, and the internal voids are easily crushed. Therefore, if it is strongly wound around the compressor 22 or the like, the internal space is crushed and the state is maintained, and the sound absorption performance may be significantly reduced. However, according to the first soundproofing material 3 </ b> A, the mark 46 is provided so that the soundproofing material main body 40 contacts the side surface of the compressor 22 while maintaining the thickness of the sound absorbing material 41 before being wound. Therefore, the internal space is prevented from being crushed by winding the first soundproofing material 3A around the compressor 22 with the position of the winding start end S aligned with the mark 46. Therefore, it is possible to effectively suppress the sound absorption performance from being lowered due to individual differences in winding work, and to enjoy the high sound absorption effect of the sound absorbing material 41 made of glass fiber.

  In addition, since the marks 46 are provided at the upper and lower ends of the soundproof material main body 40, the upper and lower ends of the winding start end S are respectively positioned at the marks 46, so that there is a difference in the amount of winding between the upper and lower sides of the compressor 22. The first soundproofing material 3A is prevented from coming out or being wound around the compressor 22 or the like at an angle. Therefore, the inconvenience that the soundproofing effect is lowered by winding the first soundproofing material 3A around the compressor 22 or the like in an inappropriate state is prevented.

  In addition, the first soundproofing material 3A is formed as a mark 46 after the soundproofing material body 40 is formed so as to be wound around a plurality of types of compressors 22 having different diameters (the diameter of the accumulator 24 is constant). A plurality of marks 46a to 46c corresponding to the types (diameters) of the compressors 22 are provided. Accordingly, there is an advantage that the above-described effects can be enjoyed for any type of compressor 22 while using the common first soundproof material 3A for the plurality of types of compressors 22.

  The first soundproofing material 3A is provided with marks 46 at both upper and lower ends of the soundproofing material main body 40. However, the number and positions of the marks 46 are not limited to this, and the soundproofing material main body 40 is arranged in the vertical direction. What is necessary is just to select suitably according to a dimension. In addition, the first soundproofing material 3A includes, as the mark 46, a diameter dimension display (φ90, φ100, φ120) of the compressor 22 and an alignment line, but the specific form of the mark 46 is also limited to this. It is not a thing. The mark 46 may be a character, a line, a notch, a hole, or the like and can determine the position of the winding end portion E. Further, the first soundproofing material 3 </ b> A does not necessarily need to include the marks 46 a to 46 c corresponding to the plurality of types of compressors 22, and may include the marks 46 corresponding to at least one type of compressor 22.

  By the way, the outdoor unit 10 mentioned above is an illustration of embodiment of the outdoor unit which concerns on this invention, Comprising: The specific structure of the outdoor unit 10 and the specific structure of the soundproof member 3 attached to the compressor 22 are as follows. Modifications can be made as appropriate without departing from the scope of the present invention.

  For example, the first soundproofing material 3A may have a configuration as described in the following (1) to (3).

  (1) FIG. 6 shows one modified example of the first soundproofing material 3A. (A) is a plan view of the unfolded state, and (b) is a side view of the unfolded state. Each of the materials 3A is shown.

  The first soundproofing material 3A has a plurality of protrusions 47 (in place of the mark 46 as positioning means for determining the position of the winding end E in the first soundproofing material 3A shown in FIGS. (Corresponding to the convex portion of the present invention). In the illustrated example, three protrusions 47 are provided that are intermittently arranged in the vertical direction. These ridges 47 have a shape capable of abutting the winding end portion E of the soundproof material main body 40, specifically, a rectangular parallelepiped shape having a rectangular shape in the vertical direction, and protrude from the surface of the sound insulating material 42. In this way, the sound insulating material 42 is integrally formed.

  In the first soundproofing material 3A, the soundproofing material main body 40 is wound around the compressor 22, and the winding terminal portion E is positioned by abutting the winding terminal portion E against the protrusion 47 as shown in FIG. According to such a first soundproofing material 3A, since both ends of the soundproofing material main body 40 can be secured by the fixing tool 45 in a state where the winding end E is abutted against the protrusion 47, the positioning accuracy is improved. To do. Further, since the winding end E is abutted against the protrusion 47, the winding end E can be positioned intuitively and reliably. Therefore, there is an advantage that the workability of the winding work of the first soundproofing material 3A is improved.

  The number, position, and shape of the protrusions 47 are not limited to those shown in the figure, and may be appropriately selected so that the winding end portion E of the soundproof material body 40 can be abutted and positioned. However, in order to prevent a difference in winding amount between the upper and lower sides of the compressor 22 and the first sound insulating material 3A from being obliquely wound around the compressor 22 and the like, the protrusion 47 is at least a sound insulating material main body. It is preferable to be provided at both upper and lower ends of 40.

  (2) FIG. 8 shows another modification of the first soundproofing material 3A. (A) is a plan view of the unfolded state, and (b) is a side view of the unfolded state. 3A is shown respectively.

  This first soundproofing material 3A has a step on the soundproofing material main body 40 in place of the mark 46 as positioning means for determining the position of the winding end E in the first soundproofing material 3A shown in FIGS. A portion 49 is provided. The step 49 is formed in the sound insulating material 42 by cutting the sound insulating material 42 in the thickness direction over the entire vertical direction in a certain region including the winding start end S of the sound insulating material main body 40. is there.

  In the first soundproofing material 3A, the soundproofing material main body 40 is wound around the compressor 22, and the winding terminal portion E is positioned by abutting the winding terminal portion E against the wall surface of the stepped portion 49 as shown in FIG. . Even with such a first soundproofing material 3A, the same effects as those of the first soundproofing material 3A described in (1) above can be achieved. In addition, according to the first soundproofing material 3A shown in FIG. 8, the thickness of the overlapping portion of the soundproofing material main body 40 increases in the overlapping direction because the sound insulating material 42 is cut out in the thickness direction. The winding end portion E can be positioned while suppressing this.

  (3) FIG. 10 shows another modification of the first soundproofing material 3A. (A) is a plan view of the unfolded state, and (b) is a side view of the unfolded state. 3A is shown respectively.

  The first soundproofing material 3A is the same as the first soundproofing material 3A shown in FIGS. 2, 3 and the like, and the end of the sound insulating material 42 on the winding end E side is used as positioning means for determining the position of the winding end E. The soundproof material main body 40 is formed so as to protrude in the winding direction from the end of the sound absorbing material 41. The mark 46 is not provided.

  In the first soundproofing material 3A, the soundproofing material main body 40 is wound around the compressor 22, and the winding end part E is brought into contact with the winding start end S by abutting the sound absorbing material 41 on the winding terminal end E side as shown in FIG. Positioning. Even with such a first soundproofing material 3A, it is possible to achieve the same effects as the first soundproofing material 3A described in (1) above.

  (4) In the above embodiment, since the accumulator 24 is fixed to the side surface of the compressor 22 (main body portion 22a), the first soundproofing material 3A is integrally wound around the compressor 22 and the accumulator 24. Yes. However, when the compressor 22 and the accumulator 24 are separated from each other, the first soundproofing material 3A only needs to be wound around the compressor 22 only.

  (5) In the above-described embodiment, the first soundproofing material 3A includes a culture urn as the fixture 45, but a hook-and-loop fastener may be applied instead of the culture urn. In short, what is necessary is just to be able to fix both ends of the soundproof material main body 40 while providing a degree of freedom in the amount of winding.

  (6) In the above embodiment, the sound absorbing material 41 of the soundproofing material main body 40 is made of a glass fiber sound absorbing material, but the sound absorbing material 41 may be a sound absorbing material made of a material other than glass fiber, such as felt. . If the sound absorbing material such as a felt is compressed and the internal gap is crushed, there may occur a case where the sound absorbing performance planned in the design cannot be enjoyed. Therefore, the configuration of the first sound insulating material 3A is useful.

  (7) In the above embodiment, an example in which the present invention is applied to an air conditioner has been described. However, the present invention is also applied to a refrigeration apparatus other than an air conditioner such as a refrigerator, a refrigerator, and a heat pump water heater. Is possible.
