[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0036] 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. Since the temperature of the pipeline is low, condensation water droplets will be generated on the pipeline and drip onto the chassis. If the condensed water is not discharged in time, there will be a problem of the risk of corrosion to the compressor on the chassis for a long time.

[0037] Please refer to Figure 1 and Figure 2 , in an embodiment of the present utility model, the sound insulation pad 100 includes a pad body 110 and a mounting portion 130. The pad body 110 is used to connect with the chassis 210; 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 sound-absorbing material.

[0038] In order to more effectively isolate vibrations, in combination with Figures 3 to 5 , in this embodiment, the mounting portion 130 is a mounting hole 131 penetrating through the pad body 110. One of the main functions of the sound insulation pad 100 is to isolate vibrations and reduce the transmission of vibrations generated during the operation of the compressor 220 to the surrounding environment. Directly fixing the mounting feet of the compressor 220 on the sound insulation pad 100 will actually form a rigid connection point, which will weaken the vibration isolation effect of the sound insulation pad 100. By opening an avoidance round hole, the mounting feet do not directly contact the sound insulation pad 100, but through other flexible or elastic elements (such as rubber gaskets, see Figures 3 to 5) Indirect connection can more effectively absorb and isolate vibrations. The design of the installation holes 131 as round holes 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 complex once the sound insulation pad 100 needs to be adjusted or replaced. In other embodiments, the mounting portion 130 is a mounting point formed of a rigid material.

[0039] Referring to Figures 3 to 5 , to solve the problem that when the compressor 220 refrigerates, 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 drained in time, there is a risk of corroding the compressor 220 on the chassis 210 for a long time. A water collecting groove 121 for collecting condensed water is designed on the sound insulation pad 100 below the pipeline of the connecting pipe 221. The sound insulation pad 100 further includes a water retaining edge 120 provided on the pad body 110. The water retaining edge 120 encloses to form a water collecting groove 121 and is provided with a drain port 122 communicating with the water collecting groove 121. The water collecting groove 121 is used to receive the condensed water generated by the connecting pipe 221 of the compressor 220. Referring to Figure 5 , Figure 5 , the direction indicated by the arrow in

[0040] In addition, referring to Figures 1 to 5 , the mounting portion 130 is located outside the water collecting groove 121, isolating the condensed water from the mounting portion 130 and further solving the problem of corrosion of the compressor 220 due to condensed water.

[0041] In this embodiment, the compressor 220 is arranged inside the air conditioner indoor unit 200. After arranging the compressor 220 inside the air conditioner indoor unit 200, the weight of the air conditioner outdoor unit can be reduced, making it more convenient for users to move the air conditioner 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 expensive. Correspondingly, it is necessary to reduce the noise generated during the operation of the compressor 220 after being arranged inside the air conditioner indoor unit 200 to improve the user experience.

[0042] To reduce noise, noise reduction treatment needs to be carried out on the compressor 220 arranged in the indoor unit. It is necessary to effectively isolate and reduce the noise generated during the operation of the compressor 220 to a certain extent, so as to ensure that when the indoor unit 200 of the air conditioner is installed indoors, the noise is within the acceptable range of users, so that users can enjoy the lightweight 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.

[0043] After the technical solution of the present utility model arranges the compressor 220 in the indoor unit 200 of the air conditioner, the weight of the outdoor unit of the air conditioner can be reduced, which is more convenient for users to move the outdoor unit of the air conditioner by themselves to find a suitable installation position, reduce the installation difficulty, and reduce the installation labor cost, especially in areas where labor costs are expensive. 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 a mounting portion 130. The mounting portion 130 is available 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 sound-absorbing material, which can absorb and reduce the sound wave energy generated by the vibration of the compressor 220, thereby reducing the outward transmission of the noise of the compressor 220. The sound insulation pad 100 is reused as a water collecting tank 121 for receiving condensed water in front of the water receiving tray 230. This design not only ensures the tightness of the water collecting tank 121, but also makes full use of the space of the sound insulation pad 100, avoiding additional space occupation. The water collecting tank 121 is communicated with the water receiving tray 230, without adding a new structure and increasing the cost; it does not increase the space of the indoor unit, which is beneficial to the compact structure of the indoor unit and is beneficial to miniaturization.

[0044] The air conditioner includes an indoor unit 200 of the air conditioner and an outdoor unit of the air conditioner (not shown in the figure). The indoor unit 200 of the air conditioner is connected to the outdoor unit of the air conditioner through a flexible refrigerant pipe; the indoor unit 200 of the air conditioner and the outdoor unit of the air conditioner can be integrally arranged. At this time, the air conditioner is a mobile air conditioner, which does not require an external exhaust pipe or an outdoor unit. All components are integrated in one unit, and the compressor 220 of the air conditioner can be further arranged in the indoor unit 200.

[0045] In this way, the air conditioner is a split-type air conditioner that is convenient for users to install personally. It uses a flexible refrigerant pipe to connect the indoor-side heat exchanger of the indoor unit 200 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, only the indoor unit 200 of the air conditioner and the outdoor unit of the air conditioner need to be fixed respectively, without the need to assemble the refrigerant pipe and add refrigerant, thereby reducing the installation difficulty and realizing personal installation by the user.

[0046] Refer to Figure 6, To facilitate the drainage of condensed water into the water receiving tray 230 and then out of the indoor unit 200 of the air conditioner through the water receiving tray 230, inside the water collecting trough 121, the bottom of the water collecting trough 121 is inclined from near the installation part 130 towards the direction away from the installation part 130 to form a first drainage slope 151. Refer to Figure 7 , a second drainage slope 152 is formed by the bottom of the water collecting trough 121 inclining towards the drainage port 122, and the bottom of the water collecting trough 121 inclines towards the drainage port 122. Drainage slopes with slopes are designed in both the horizontal and vertical directions of the water receiving tray 230. A drainage port 122 communicating with the water collecting trough 121 is provided on the water collecting trough 121. This design enables the condensed water in the water collecting trough 121 to be drained smoothly. When the condensed water accumulates to a certain extent, it will flow into the water receiving tray 230 of the chassis 210 through the drainage port 122, thus avoiding the risk of condensed water staying on the chassis 210 for a long time and corroding the compressor 220, effectively draining the condensed water in the water collecting trough 121, preventing it from gathering near the compressor 220 and corroding the compressor 220, and shortening the service life of the equipment.

[0047] In other solutions, a water guide trough structure formed by convex points or a water guide trough structure formed by grooves can also be provided at the confluence of the first drainage slope 151 and the second drainage slope 152.

[0048] Refer to Figure 8 , To prevent the condensed water from being blocked at the drainage port 122 due to surface tension, in this embodiment, a water breaking port 123 is designed at the position of the condensed water drainage port 122, which is used to break the surface tension of the water itself, facilitate the rapid flow of the condensed water to the water receiving tray 230 of the chassis 210, and prevent the condensed water from gathering and overflowing at the drainage port 122.

[0049] The design principle of the water breaking port 123 is that when the condensed water accumulates at the drainage port 122 and is affected by the surface tension, these water droplets may form a relatively stable liquid surface and are not likely to flow into the water receiving tray 230 of the chassis 210 by themselves. The function of the water breaking port 123 is to provide a breakthrough point or reduce the surface tension effect, enabling the condensed water to more easily overcome the surface tension and thus accelerate the flow into the water receiving tray 230. Specifically, the water breaking port 123 can be a small opening, groove or a structure with a specific shape. Its size and shape need to be designed according to the actual situation to ensure that it can effectively break the water tension without having an adverse impact on the overall structure and function of the sound insulation pad 100. In addition, the design of the water breaking port 123 also needs to consider the drainage efficiency and the prevention of debris entry. For example, it can be designed as a downward inclined slope so that the condensed water can smoothly flow along the slope into the water receiving tray 230. In this embodiment, the water breaking port 123 is arranged in the middle of the bottom of the drainage port 122, closer to the water outlet direction side of the drainage trough.

[0050] Refer to Figures 1 to 7, 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 upward open mounting notch 141 for placing and limiting the connecting pipe 221 of the compressor 220. After the pipeline of the compressor 220 exits the pipe, due to the lack of an obvious positioning device, misalignment is likely to occur during welding, affecting 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 card slot. The connecting pipe 221 coming out of the compressor 220 needs to be inserted into the middle of the limiting card 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 for placing one connecting pipe 221. In this way, all pipeline outlets pass through the limiting card slot, solving problems such as easy breakage and misalignment interference of the connecting pipe 221 during the assembly process, such as during welding, which affect the assembly efficiency and quality.

[0051] To prevent the disengagement of the connecting pipe 221, the mounting notch 141 and the connecting pipe 221 are in a snap-fit. Since the sound insulation pad 100 is made of a flexible material, no pipe abrasion problem will occur when the pipe placement seat 140 comes into contact with the pipeline. In one embodiment, snap protrusions can be provided on both sides of the mounting notch 141 to limit the disengagement of the connecting pipe 221. In other embodiments, the mounting notch 141 is tapered near the opening.

[0052] In this embodiment, the sound insulation pad 100 is integrally formed. After the sound insulation pad 100 is arranged on the chassis 210, the compressor 220 is fixed to the chassis 210 through the mounting holes 131. The connecting pipe 221 of the compressor 220 is snap-fitted on the pipe placement seat 140, and the pipeline is welded. A water collecting trough 121 is provided below the pipeline formed by the connecting pipes 221. The condensed water generated during the refrigeration process of the compressor 220 will fall into the water collecting trough 121. The bottom of the water collecting trough 121 is provided with a first drainage slope 151 and a second drainage slope 152 with an inclined angle, so that the condensed water is collected at the drainage port 122 and flows into the water receiving tray 230 of the chassis 210 from the drainage port 122. The bottom of the drainage port 122 is provided with a water breaking port 123, which can prevent the condensed water from accumulating and overflowing at the drainage port 122 and drain into the water receiving tray 230 more quickly.

[0053] In summary, when the compressor 220 operates, it will generate 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 propagation 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 and the problem of condensate water accumulating at the compressor 220 and corroding the compressor 220 are solved.

[0054] 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 in other related technical fields, is included in the patent protection scope of the present invention.
