Description

Technical Field

[0001] The utility model relates to the technical field of silencing and noise reduction, and in particular to a sound-absorbing cotton, a compressor and a heat pump. Background Art

[0002] Sound-absorbing cotton, also known as silencing cotton, is a rolled or sheet material made from a single or multiple fibers through various processing techniques. It offers excellent sound absorption and insulation, and is heat and corrosion resistant. Existing compressors typically use silencing cotton in a single piece, wrapping the compressor and its piping to achieve sound insulation and noise reduction.

[0003] However, the shape of the silencer cotton after wrapping the compressor and its piping has large rounded corners, and its tightness is difficult to control. This can easily cause the silencer cotton to interfere with the sheet metal or piping after assembly, causing the compressor resonance noise to be transmitted to other components of the unit, making the unit noisier. Moreover, the silencer cotton that matches the compressor usually needs to be made with large rounded corners or directly into a circular structure according to the shape of the sheet metal shell to be assembled, which is not easy to process using conventional cutting dies.

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0027] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0028] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0029] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0030] Silencing cotton, also known as sound-absorbing cotton, is a roll / sheet material made of a single or multiple different fibers through a variety of processes. It has good sound absorption performance, strong sound insulation ability, high temperature resistance, and corrosion resistance. The existing compressors use silencer cotton, which is mostly formed in one piece, to wrap the compressor and its pipelines to achieve sound insulation and noise reduction effects. However, the shape of the silencer cotton after wrapping the compressor and its pipelines has large rounded corners, and its tightness is difficult to control, which can easily cause the silencer cotton to interfere with the sheet metal or pipeline after assembly, thereby causing the compressor resonance noise to be transmitted to other parts of the unit, making the unit noise louder. Moreover, the silencer cotton that matches the compressor usually also needs to be made into a structure with large rounded corners or directly made into a circular shape according to the shape of the sheet metal shell that needs to be assembled. It is not easy to process using conventional cutting dies.

[0031] Based on this, see Figure 1 , the sound-absorbing cotton 100 provided in the embodiment of the present invention can effectively improve the technical problems mentioned above. The sound-absorbing cotton 100 can avoid the transmission of resonant noise caused by the interference between the sound-absorbing cotton 100 and the pipes, sheet metal and other assembly parts due to assembly errors. At the same time, the sound-absorbing cotton 100 is also convenient for assembly and molding, and has a beautiful appearance after assembly. In addition, the sound-absorbing cotton 100 is also easy to process. The sound-absorbing cotton 100 can be applied to the surface of devices that require sound insulation and noise reduction, such as compressors, and compressors are used in heat pumps or other refrigeration equipment. Devices such as compressors and heat pumps with sound insulation and noise reduction that have the sound-absorbing cotton 100 all have the same functions as mentioned above, which will not be repeated here.

[0032] The heat pump provided in this embodiment (not shown) includes a compressor, an evaporator, a condenser, and an expansion valve. These devices work together to transfer heat from the environment to the heating object through a thermodynamic cycle of evaporation (absorbing energy from the environment), compression, condensation (releasing energy), throttling, and re-evaporation of the working fluid. The evaporator is a key component in a heat pump system, responsible for absorbing heat from the environment. The condenser releases the absorbed heat to the medium to be heated. The compressor compresses the working fluid, increasing its pressure and temperature so that it can release heat in the evaporator. The expansion valve controls the flow of the working fluid through the evaporator, thereby regulating the output of the heat pump. Different types of heat pump devices differ in their specific applications. For example, a water-source heat pump uses water as its heat source and transfers heat through a refrigerant; an air-source heat pump uses air as its heat source and also transfers heat through a refrigerant. These heat pump devices are widely used in heating, hot water supply, and other fields, effectively utilizing low-grade thermal energy to achieve energy savings. Of course, heat pumps can also include other structures to achieve various functions, which are not limited here.

[0033] The compressor mentioned above, specifically, the compressor in this embodiment includes an outer shell and sound-absorbing cotton 100. The outer shell is provided with sound-absorbing cotton 100, and the first dividing line 110 is located at the turning position of the outer shell. The outer shell includes a top cover and a shell. The surface of the top cover is provided with a piece of sound-absorbing cotton 100, the side wall of the top cover is provided with a piece of sound-absorbing cotton 100, and the outer surface of the shell is also provided with a piece of sound-absorbing cotton 100. Each piece of sound-absorbing cotton 100 is provided with a first dividing line 110 at the turning position according to the shape of each part of the outer shell, and is bent and assembled to the outer shell. Of course, one or more pieces of sound-absorbing cotton can be used in various parts according to the shape of the outer shell, as long as the outer shell can be completely covered to insulate and reduce noise. The number and shape of the sound-absorbing cotton 100 pasted on the outside of the outer shell are determined according to the use requirements and are not limited here.

[0034] Figure 1 This is a schematic diagram of a sound-absorbing cotton 100 with Velcro provided in an embodiment of the present invention, as shown in FIG. Figure 1 As shown, the silencer 100 in this embodiment is provided with a first dividing line 110, allowing it to bend at the location of the first dividing line 110 during assembly. This first dividing line 110 makes it easier to assemble the silencer 100 into designed corners when it is assembled on the surface of a compressor casing or other device, ensuring that the silencer 100 fits perfectly with the component to be assembled. This prevents interference between the silencer 100 and piping, sheet metal, and other components due to assembly errors, which can lead to resonant noise transmission. This also ensures an aesthetically pleasing appearance after assembly. Furthermore, this design facilitates processing of the silencer 100.

[0035] See also Figure 1 To facilitate the assembly of the silencer cotton 100 onto the accessory and simplify the installation process, the silencer cotton 100 in this embodiment is provided with first hook-and-loop strips 200 at both ends of the lengthwise direction parallel to the first dividing line 110. Specifically, the first hook-and-loop strips 200 at one end of the silencer cotton 100 in this embodiment have a fleece surface, while the first hook-and-loop strips 200 at the other end have a hook surface. The fleece and hook surfaces can cooperate and bond to each other to achieve the connection and fixation of the silencer cotton 100. This means that the same silencer cotton 100 can be connected end to end, and two adjacent silencer cottons 100 can also be overlapped using the first hook-and-loop strips 200. In addition to hook-and-loop strips, the silencer cotton 100 can also be connected using glue, double-sided tape, or snaps, etc., without limitation here.

[0036] In order to make the installation of the silencer cotton 100 easier and the Velcro more tightly attached, please continue to refer to Figure 1In this embodiment, the sound-absorbing cotton 100 is provided with a second hook-and-loop fastener 300 at at least one end perpendicular to the length of the first dividing line 110. Because the fleece surface of the hook-and-loop fastener is relatively rigid and difficult to bend and shape, a second dividing line 310 is provided on the second hook-and-loop fastener 300 in this embodiment. The length of the second dividing line 310 is the same as the width of the second hook-and-loop fastener 300. At the location of the second dividing line 310, the second hook-and-loop fastener 300 can also be bent to conform to the shape of the accessory to be assembled. The same length of the second dividing line 310 as the width of the second hook-and-loop fastener 300 makes bending the second hook-and-loop fastener 300 easier and more convenient.

[0037] In order to facilitate the shaping of the silencer cotton 100 during assembly, the length L of each first cutting line 110 in this embodiment is greater than or equal to the distance D between two adjacent first cutting lines 110. Of course, the length L of the first cutting line 110 can also be less than the distance D between two adjacent first cutting lines 110, which is not limited here. The dimensional relationship between the length L of the first cutting line 110 and the distance D between two adjacent first cutting lines 110 needs to be determined according to the different thicknesses and different material combinations of the silencer cotton 100. For example, if the silencer cotton 100 is composed of a single layer of cotton and a single layer of leather and the silencer cotton 100 is composed of a double layer of cotton and a layer of rubber in the middle, the size combination of the first cutting line 110 that needs to be designed is different. The length L of the first cutting line 110 and the distance D between two adjacent first cutting lines 110 need to be adjusted according to actual conditions.

[0038] Specifically, see Figure 2 , Figure 2 This is a schematic diagram of the first type of sound-absorbing cotton 100 provided in an embodiment of the present invention. In this embodiment, the sound-absorbing cotton 100 may be provided with only a single first dividing line 110. Specifically, a slit may be made at one location on a complete piece of sound-absorbing cotton 100 to form the first dividing line 110. During assembly, the sound-absorbing cotton 100 with the single first dividing line 110 can be folded into an "L" shape. Of course, the sound-absorbing cotton 100 may also be folded into a "V" shape or other shapes depending on the shape of the part to be assembled, and this is not limited here.

[0039] In order to adapt to the various shapes of the parts to be assembled with the sound-absorbing cotton 100, the number of the first cutting lines 110 in this embodiment is multiple, and the multiple first cutting lines 110 are arranged at intervals. Specifically, Figure 3 This is a schematic diagram of the second type of sound-absorbing cotton 100 provided in the embodiment of the present invention, please refer to Figure 3In this embodiment, there are two first cutting lines 110, and the sound-absorbing cotton 100 can be bent into a U-shape or a triangle. Specifically, the sound-absorbing cotton 100 is slit at any two locations to form two first cutting lines 110. During assembly, the sound-absorbing cotton 100 in this embodiment can be bent into a "U" shape, a triangle, or other irregular shapes, depending on the shape of the assembly part, and is not limited here.

[0040] Figure 4 This is a schematic diagram of the third type of sound-absorbing cotton 100 provided in the embodiment of the present invention, please refer to Figure 4 The sound-absorbing cotton 100 in this embodiment is cut at any three positions to form three first cutting lines 110. During assembly, the sound-absorbing cotton 100 in this embodiment can be bent into a quadrilateral. Of course, it can also be bent into other regular or irregular shapes, depending on the shape of the parts to be assembled, and is not limited here.

[0041] In addition, based on the conventional design of a whole piece of silencer cotton 100, a slit is made at the position where the silencer cotton 100 needs to turn during assembly to form a first cutting line 110. The position and number of the slits required can be determined according to the number of corners required for the assembly of the silencer cotton 100, and are not limited here.

[0042] According to the sound-absorbing cotton 100 provided in this embodiment, its working principle is as follows:

[0043] When processing the silencer cotton 100, a first cutting line 110 is set at the corresponding position of the silencer cotton 100 according to the turning position of the part to be assembled. During assembly, the first cutting line 110 of the silencer cotton 100 is located at the corner of the part to be assembled, such as the shell of the compressor. At the position of the first cutting line 110, the silencer cotton 100 is easy to bend, and the silencer cotton 100 can be bent into a shape that fits the shell, thereby avoiding noise caused by assembly errors.

[0044] In summary, the silencer 100 is provided with a first dividing line 110, allowing it to bend at the location of the first dividing line 110 during assembly. This first dividing line 110 makes it easier to assemble the silencer 100 into the designed corners when it is assembled on the surface of a compressor casing or other device, ensuring that the silencer 100 fits perfectly with the component to be assembled. This prevents interference between the silencer 100 and the pipes, sheet metal components, and other components to be assembled due to assembly errors, which can cause resonant noise transmission. This also ensures an aesthetically pleasing appearance after assembly. Furthermore, this design facilitates processing of the silencer 100.

[0045] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
