[0039] When the compressor operates, it will generate mechanical vibrations and sounds. If the sounds generated by the compressor are directly transmitted to the indoor space without proper sound insulation measures, it will cause noise pollution. In addition, at the same time, the pipelines of the compressor are prone to misalignment interference during assembly and operation, such as during welding, and are prone to pipeline deformation and fracture during operation, affecting the assembly efficiency and quality.

[0040] Therefore, the present utility model proposes a sound insulation pad and an air conditioner. By arranging between the chassis and the compressor, the sound insulation pad is made of an elastic damping material, which can isolate and reduce the sound wave energy generated by the compressor vibration, thereby reducing the outward transmission of compressor noise. A pipe seat is further designed on the sound insulation pad to limit the connecting pipes of components such as the compressor through the pipe seat, solving the problems that the connecting pipes are prone to misalignment interference during assembly and operation, such as during welding, and are prone to pipeline deformation and fracture during operation, affecting the assembly efficiency and quality.

[0041] Please refer to Figures 1 to 6 , in an embodiment of the present utility model, referring to Figure 1 and Figure 2 , the sound insulation pad 100 includes a pad body 110 and a mounting portion 130. Referring to Figure 6 , the pad body 110 is used to be connected to the chassis 210, such as by screwing, gluing, snap-limiting, etc.; the mounting portion 130 is provided on the pad body 110, and the mounting portion 130 is used for the compressor 220 to be installed. The sound insulation pad 100 is made of an elastic damping material.

[0042] The air conditioner includes an indoor unit 200 of the air conditioner and an outdoor unit of the air conditioner. The indoor unit 200 of the air conditioner is connected to the outdoor unit through a flexible refrigerant pipe; and the compressor 220 of the air conditioner can be further arranged in the indoor unit 200 of the air conditioner.

[0043] Normally, the compressor 220 is arranged in the outdoor unit of the air conditioner. However, for the convenience of installing the outdoor unit of the air conditioner, the compressor 220 is arranged in the indoor unit 200 of the air conditioner. After arranging the compressor 220 in the indoor unit of the air conditioner, the weight of the outdoor unit of the air conditioner can be reduced, so that it is more convenient for users to move the outdoor unit of the air conditioner by themselves to find a suitable installation position, reducing the installation difficulty and the installation labor cost, especially in areas where the labor cost is expensive. Accordingly, it is necessary to reduce the noise during the operation of the compressor 220 arranged in the indoor unit 200 of the air conditioner to improve the user experience.

[0044] In this way, the air conditioner is a split-type air conditioner that is convenient for users to install personally. It uses flexible refrigerant pipes to connect the indoor-side heat exchanger of the indoor unit of the air conditioner and the outdoor-side heat exchanger of the outdoor unit of the air conditioner, and injects refrigerant into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by himself, he only needs to fix the indoor unit of the air conditioner and the outdoor unit of the air conditioner respectively, without the need to assemble the refrigerant pipes and fill the refrigerant, thus reducing the installation difficulty and realizing personal installation by the user.

[0045] In order to reduce the noise, it is necessary to perform noise reduction treatment on the compressor 220 arranged in the indoor unit, and effectively isolate and reduce the noise generated during the operation of the compressor 220 to a certain extent to ensure that when the indoor unit 200 of the air conditioner is installed indoors, the noise is within the acceptable range of the user, so that the user can enjoy the light and easy-to-install outdoor unit of the air conditioner without being disturbed by the compressor 220 of the indoor unit 200 during rest or work. After arranging the compressor 220 in the indoor unit of the air conditioner, the weight of the outdoor unit of the air conditioner can be reduced, so that it is more convenient for users to move the outdoor unit of the air conditioner by themselves to find a suitable installation position, reducing the installation difficulty and the installation labor cost, especially in areas where the labor cost is expensive. Accordingly, for the noise reduction of the compressor 220, by arranging the sound insulation pad 100 between the chassis 210 and the compressor 220, the sound insulation pad 100 includes a pad body 110 and an installation part 130, the installation part 130 is for the compressor 220 to be installed, the pad body 110 is arranged on the chassis 210 and can be clamped by a buckle 111, and the sound insulation pad 100 is made of an elastic damping material, which can isolate and reduce the sound wave energy generated by the vibration of the compressor 220, thereby reducing the transmission of the compressor 220 noise outward, without increasing the space of the indoor unit 200 of the air conditioner, being beneficial to the structural compactness of the indoor unit 200 of the air conditioner and being beneficial to miniaturization.

[0046] Refer to Figure 1 、 Figure 2 and Figure 5 and Figure 6, in order to more effectively isolate vibration, in this embodiment, the installation part 130 is an installation hole 131 penetrating through the pad body 110. One of the main functions of the sound insulation pad 100 is to isolate vibration and reduce the transmission of vibration generated during the operation of the compressor 220 to the surrounding environment. By providing a relief round hole, the mounting feet do not directly contact the sound insulation pad 100, but are indirectly connected through other flexible or elastic elements (such as rubber washers), which can more effectively isolate vibration. The design of the installation hole 131 as a round hole also provides greater flexibility, facilitating the installation, disassembly, and adjustment of the compressor 220. If the mounting feet are directly fixed to the sound insulation pad 100, the operation will become more complicated once the sound insulation pad 100 needs to be adjusted or replaced. In other embodiments, the installation part 130 is an installation point formed of a rigid material.

[0047] Combined with Figure 3 and Figure 4 , in order to fix the connecting pipe of the compressor 220, the sound insulation pad 100 further includes a pipe placement seat 140. The pipe placement seat 140 is provided with an upwardly open mounting notch 141. The mounting notch 141 is in snap-fit with the connecting pipe 221, and the mounting notch 141 is used to place and limit the connecting pipe 221 of the compressor 220. After the pipeline of the compressor 220 exits, there is no obvious positioning device, so it is easy to be misaligned during welding, which affects the assembly efficiency of production. A plurality of pipe placement seats 140 are also designed on the sound insulation pad 100. The pipe placement seat 140 is provided with a U-shaped limiting slot. The connecting pipe 221 coming out of the compressor 220 needs to be snapped into the middle of the limiting slot. In order to improve the welding efficiency, the number of pipe placement seats 140 corresponds to the number of connecting pipes 221 of the compressor 220. One pipe placement seat 140 is used to accommodate one connecting pipe 221. In this way, all pipeline outlets pass through the limiting slots, which can not only effectively ensure the welding correctness of the pipeline, but also improve the welding efficiency of the pipeline. There is no need to find the pipeline position during welding.

[0048] After arranging the compressor 220 inside the indoor unit 200 of the air conditioner, the technical solution of the present utility model can reduce the weight of the outdoor unit of the air conditioner, making it more convenient for users to move the outdoor unit by themselves to find a suitable installation position, reducing the installation difficulty and the installation labor cost, especially in areas where the labor cost is high. Correspondingly, in order to reduce the noise of the compressor 220, by arranging the sound insulation pad 100 between the chassis 210 and the compressor 220, the sound insulation pad 100 includes a pad body 110 and an installation part 130. The installation part 130 is for the compressor 220 to be installed. The pad body 110 is arranged on the chassis 210. The sound insulation pad 100 is made of an elastic damping material, which can isolate and reduce the sound wave energy generated by the vibration of the compressor 220, thereby reducing the outward propagation of the noise of the compressor 220. The sound insulation pad 100 is designed with a pipe support seat 140 to support the connecting pipe 221, avoiding the connecting pipe 221 from hanging in the air without support, which may cause the connecting pipe 221 to displace during the assembly process, or be easily misaligned during welding, and the pipeline is easily deformed or broken during operation, affecting the assembly efficiency and quality.

[0049] In order to prevent the disconnection of the connecting pipe 221, the pipe support seat 140 is provided with a limiting structure, and the limiting structure is used to limit the disconnection of the connecting pipe 221 from the installation notch 141. The installation notch 141 and the connecting pipe 221 are in a snap-fit. Since the sound insulation pad 100 is made of a flexible material, there will be no pipe grinding problem even if the pipe support seat 140 contacts the pipeline. In one embodiment, clamping protrusions can be provided on both sides of the installation notch 141 to limit the disconnection of the connecting pipe 221. In other embodiments, the installation notch 141 is tapered towards the opening.

[0050] Refer to Figure 4 , specifically, two pipe support seats 140 are arranged at intervals along the pipe outlet direction of the connecting pipe 221 of the compressor 220. The pipe support seat 140 close to the compressor 220 has two installation notches 141 with different horizontal and vertical directions and different heights from the pad body 110. One installation notch 141 is for one connecting pipe 221 to be placed. The connecting pipe 221 of the compressor 220 extends downward from the top, bends and extends out of the opening of the casing. The two pipe support seats 140 are arranged at intervals to "support" the connecting pipe 221, ensuring the stability of the connecting pipe 221. The thin pipe extending from the electronic expansion valve extends in different directions from the connecting pipe 221 to be connected to the heat exchanger.

[0051] Refer to Figure 3, to solve the problem that when the compressor 220 is refrigerating, due to the low temperature of the pipeline, condensation water will be generated on the pipeline and drip onto the chassis 210. If the condensed water is not discharged in time, there is a risk of corroding the compressor 220 on the chassis 210 for a long time. The surface of the pad body 110 faces the water receiving tray 230 with an inclined drainage slope 150. Through the inclined setting of the drainage slope 150, the condensed water flows into the water receiving tray 230 under the action of gravity, avoiding accumulation at the compressor 220, thereby avoiding the risk of condensed water existing on the chassis 210 for a long time and corroding the compressor 220, enabling the effective discharge of the condensed water in the water collecting trough, avoiding accumulation near the compressor 220, corroding the compressor 220, and shortening the service life of the equipment.

[0052] To facilitate the discharge of condensed water, the pad body 110 can also be provided with a water guiding structure to facilitate the rapid flow of condensed water into the water receiving tray 230 of the chassis 210, avoiding the dispersion and overflow of condensed water. Specifically, the water guiding structure can be a convex rib, convex point, groove in a graphic shape or a structure with a specific shape, and its size and shape need to be designed according to the actual situation to ensure that it can effectively produce a guiding effect without having an adverse impact on the overall structure and function of the sound insulation pad 100.

[0053] In this embodiment, the sound insulation pad 100 is integrally formed. After arranging the sound insulation pad 100 on the chassis 210, the compressor 220 is fixed to the chassis 210 through the mounting hole 131, the connecting pipe 221 of the compressor 220 is clamped on the pipe seat 140, and the pipeline is welded; the dripping condensed water is guided to the water receiving tray through the drainage slope 150 and the water guiding structure.

[0054] In a further solution, a water collecting trough is provided below the pipeline formed by the connecting pipe 221. The condensed water generated during the refrigeration process of the compressor 220 will fall into the water collecting trough. The bottom of the water collecting trough is set as a drainage slope 150 with an inclined angle, so that the condensed water is collected at the drainage port and flows into the water receiving tray 230 of the chassis 210 from the drainage port; a water breaking port is provided at the bottom of the drainage port, which can avoid the accumulation and overflow of condensed water at the drainage port and discharge it into the water receiving tray 230 more quickly.

[0055] In summary, when the compressor 220 operates, it generates mechanical vibrations and sounds. Usually, the compressor 220 is arranged in the outdoor unit of the air conditioner. However, for the convenience of installing the outdoor unit of the air conditioner, the compressor 220 is arranged in the indoor unit 200 of the air conditioner. If there are no appropriate sound insulation measures, the sound generated by the compressor 220 will be directly transmitted to the indoor space, causing noise pollution. After using the sound insulation pad 100, for the indoor unit 200 of the air conditioner equipped with the compressor 220, the noise generated during its operation can be properly handled. It can effectively block and reduce the outward transmission of the noise of the compressor 220, improving the user's comfort level. Moreover, at the same time, through the design of the sound insulation pad 100, the positioning problem of the pipeline of the compressor 220 is solved, and the problem of condensate water accumulating at the compressor 220 and corroding the compressor 220 is solved.

[0056] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
