[0043] The water pump is a crucial component of an air conditioner, primarily used to drain condensate outdoors and prevent it from accumulating inside the unit, thus avoiding leaks and bacterial growth. However, existing air conditioner water pumps tend to generate significant noise during operation, negatively impacting the user experience and the air conditioner's performance.

[0044] Air conditioners typically use a compressor to circulate refrigerant between indoor and outdoor heat exchangers to achieve cooling or heating. During operation, condensation inevitably occurs on the indoor heat exchangers. For example, during cooling, water vapor in the indoor air condenses into water upon contact with the low-temperature indoor heat exchanger; during heating, water vapor in the outdoor air condenses into water upon contact with the low-temperature outdoor heat exchanger, or it frosts off the outdoor heat exchanger and turns back into water after defrosting. When a large amount of condensation accumulates in the air conditioner's chassis, a water pump is typically used to drain it outdoors. During this process, the water pump generates electromagnetic noise. Furthermore, if there is insufficient condensation at the pump's inlet, the pump may run dry, resulting in additional noise.

[0045] To solve this technical problem, this utility model proposes an air conditioner.

[0046] Please see Figures 1 to 7 In one embodiment of this utility model, the air conditioner includes a chassis 10, a water pump 20, and a soundproof cover 30. A water tank 11 is provided on the chassis 10, and an indoor heat exchanger is also provided on the chassis 10. The water tank 11 is used to collect condensate generated by the indoor heat exchanger. The water pump 20 is installed on the water tank 11. The soundproof cover 30 is provided over the water pump 20 to reduce the noise when the water pump 20 is working.

[0047] In the technical solution of this utility model, the water pump 20 is installed on the water tank 11 to make reasonable use of the space inside the water tank 11, and at the same time, the water pump 20 can directly draw the condensate collected in the water tank 11. A soundproof cover 30 is also provided outside the water pump 20, which can effectively eliminate the electromagnetic noise and dry-running noise generated when the water pump 20 is working, thereby improving the performance of the air conditioner and enhancing the user experience.

[0048] Please see Figure 1 and Figure 3In an embodiment of this utility model, the water tank 11 includes a water storage area 111 and a water extraction area 112. A partition plate 12 is provided on the chassis 10 to separate the water storage area 111 and the water extraction area 112. The soundproof cover 30 covers the water extraction area 112 and is connected to the partition plate 12 to form a receiving cavity 32 for the water pump 20 to be housed. Specifically, the water storage area 111 of the chassis 10 is used to collect condensate generated on the indoor heat exchanger during air conditioner operation. The water storage area 111 is connected to the water extraction area 112 and is equipped with a water pump 20 so that the water pump 20 directly extracts water entering the water extraction area 112, thereby discharging the condensate from the water tank 11 into the air conditioner. The partition plate 111... 2. As the dividing structure between the water storage area 111 and the pumping area 112, it can be formed by an upward-facing recess of the bottom wall of the chassis 10, or it can be fixed to the bottom wall of the chassis 10 by means of bonding, welding, etc. Furthermore, the partition plate 12 can be equipped with a filter structure to filter the water entering the pumping area 112, reducing the possibility of blockage of the water pump 20. A soundproof cover 30 is installed over the pumping area 112. Specifically, the fixed connection between the soundproof cover 30 and the partition plate 12 constructs a sound-insulating cavity 32 at the location of the pumping area 112. When the water pump 20 is installed in the cavity 32, the electromagnetic noise and dry-running noise generated by the water pump 20 during operation can be blocked and eliminated within the cavity 32, thereby improving the sound quality and performance of the air conditioner. However, this design is not limited to this. In other embodiments, the soundproof cover 30 is located within the pumping area 112 and covers the water pump 20.

[0049] Specifically, in this embodiment of the invention, the soundproof cover 30 is installed above the partition plate 12. Thus, the partition plate 12 supports and limits the soundproof cover 30, forming a relatively independent and sound-insulating cavity 32. This also increases the volume of the cavity 32 to facilitate the housing of the water pump 20 and to accommodate a sufficient amount of condensate. However, this design is not limited to this. In other embodiments, the soundproof cover 30 is arranged around the outer periphery of the partition plate 12, which also forms a cavity 32 for the water pump 20.

[0050] Please see Figure 2 In this embodiment of the invention, a slot 125 is provided above the partition plate 12, and the opening edge of the soundproof cover 30 is inserted into the slot 125. This facilitates the quick installation of the soundproof cover 30 onto the partition plate 12, improving the assembly efficiency of the soundproof cover 30. However, this design is not limited to this. In other embodiments, the slot 125 is located on the inner or outer side of the partition plate 12.

[0051] Specifically, in an embodiment of this utility model, a first surrounding rib 13 and a second surrounding rib 14 are connected above the partition plate 12. The first surrounding rib 13 and the second surrounding rib 14 are arranged at intervals in the direction from the water pumping area 112 to the water storage area 111, so as to form the slot 125 with the upper surface of the partition plate 12, thereby realizing the installation of the soundproof cover 30 above the partition plate 12 through the slot 125. At least one of the first surrounding rib 13 and the second surrounding rib 14 is spaced apart from the wall of the soundproof cover 30 to ensure smooth insertion of the soundproof cover 30. The first surrounding rib 13 is located inside the second surrounding rib 14, and the height of the first surrounding rib 13 can be less than the height of the second surrounding rib 14. This can not only restrain the lateral movement of the soundproof cover 30 on the partition plate 12, but also reduce the amount of material used, save costs, and reduce the overall weight of the chassis 10.

[0052] In this design, the second rib 14 is configured as a mounting buckle, and the soundproof cover 30 has a buckle hole 31 that mates with the mounting buckle. Thus, by configuring the second rib 14 as a mounting buckle, during the insertion of the soundproof cover 30 into the slot 125, the buckle's buckle protrusion 141 engages with the buckle hole 31, achieving assembly of the soundproof cover 30 onto the partition plate 12. Compared to screw connections, this method is simpler and requires no tools for assembly and disassembly of the soundproof cover 30, improving assembly and disassembly efficiency. Furthermore, a reinforcing rib is provided on the side of the second rib 14 facing away from the first rib 13. This reinforcing rib can also connect to the upper surface of the partition plate 12, increasing the connection strength between the second rib 14 and the partition plate 12, thereby ensuring a secure connection between the soundproof cover 30 and the partition plate 12. However, this design is not limited to this. In other embodiments, the first rib 13 is configured as a mounting buckle; or the soundproof cover 30 is directly snapped together with the partition plate 12 or the chassis 10 without the slot 125.

[0053] Optionally, in an embodiment of the present invention, the first rib 13 includes a plurality of spaced ribs, and the second rib 14 is at least partially located between two adjacent ribs. Thus, each rib extends along the extension direction of the partition plate 12 and is spaced apart, which can reduce the amount of material used while playing a limiting role. The second rib 14 is located between two adjacent ribs, which facilitates the processing of the second rib 14 without affecting the insertion effect of the soundproof cover 30.

[0054] Optionally, in an embodiment of this invention, the soundproof cover 30 is made of a sound-damping material. This material can convert mechanical vibration into heat energy and dissipate it, thereby reducing sound propagation and vibration. Using a sound-damping material for the soundproof cover 30 creates a sound-insulating cavity 32 between the cover 30 and the chassis 10. When the water pump 20 is housed within the cavity 32 and is running, the noise generated by the water pump 20 is confined within the cavity 32, preventing noise from propagating to the outside. Of course, other materials that can reduce sound propagation and vibration are also suitable for this invention, such as composite structural materials and rubber / plastics.

[0055] Please see Figures 3 to 5 In this embodiment of the present invention, the water pump 20 is connected to a drain pipe 22, and the partition plate 12 is also provided with a water pipe groove 121 for installing the drain pipe 22. This helps to regulate the direction of the drain pipe 22 in the receiving cavity 32 and ensures the rapid discharge of condensate. The first rib 13 can be disconnected at the water pipe groove 121 to facilitate the guidance and disassembly of the drain pipe 22. A limit buckle can also be provided on the outside of the chassis 10 to further limit the direction of the drain pipe 22, thereby ensuring the correct installation of the drain pipe 22 on the chassis 10 and its extension out of the chassis 10. Of course, the limit buckle can also be provided at the groove opening of the water pipe groove 121.

[0056] Please see Figures 3 to 4 In an embodiment of this utility model, the partition plate 12 is further provided with a wiring groove 122 for mounting the wire harness 24. The wire harness 24 is electrically connected to the water pump 20. This helps to organize the wire harness 24 in the receiving cavity 32 and ensure the normal driving of the water pump 20. The first surrounding rib 13 can be disconnected at the wiring groove 122 to facilitate the guidance and disassembly of the wire harness 24.

[0057] Please see Figures 3 to 4 In an embodiment of this utility model, the air conditioner further includes a filter structure 40 installed on the partition plate 12. The filter structure 40 is provided with filter holes 41 that connect the water storage area 111 and the water pumping area 112. In this way, the filter holes 41 of the filter structure 40 can filter the condensate in the water storage area 111, improve the cleanliness of the condensate entering the water pumping area 112 and the water pump 20, and reduce the possibility of impurities clogging the water pump 20 and affecting the normal operation of the water pump 20.

[0058] Specifically, in the embodiments of this utility model, the partition plate 12 is provided with a filter channel 124 communicating with the receiving cavity 32, and the filter structure 40 is limited and installed in the filter channel 124, which can not only facilitate the disassembly and assembly of the filter structure 40, but also ensure that the filter structure 40 plays a filtering role.

[0059] Specifically, the filter structure 40 includes a mounting frame and a filter screen. The mounting frame has mounting holes for assembling the filter screen, and the filter screen has filter holes 41. A vertically extending mounting groove 123 is provided on the channel wall of the filter channel 124. The filter structure 40 is inserted into the mounting groove 123 through its mounting frame, and the filter screen is exposed in the filter channel 124, realizing the detachable assembly and disassembly of the filter structure 40 and the connection between the water storage area 111 and the water pumping area 112. To further improve the assembly and disassembly efficiency of the filter structure 40 and to facilitate cleaning and replacement of the filter structure 40, such as... Figure 5 As shown, without obstructing the filter holes 41, the inner wall of the filter channel 124 is provided with a mounting limiting rib 15. The mounting limiting rib 15 abuts against the surface of the filter structure 40 facing the receiving cavity 32, and the mounting limiting rib 15 is also connected to the chassis 10. Thus, by setting the mounting limiting rib 15, the structural stability of the filter channel 124 can be enhanced, and the installation stability of the filter structure 40 can be improved by increasing the effective contact area between the filter structure 40 and the chassis 10. And / or, the chassis 10 is also provided with a guide limiting rib 16. The guide limiting rib 16 abuts against the surface of the filter structure 40 away from the receiving cavity 32. Therefore, after the filter structure 40 is inserted into the mounting groove 123, the mounting limiting rib 15 and the guide limiting rib 16 are respectively located on opposite sides of the filter structure 40, further improving the installation stability of the filter structure 40, thereby ensuring the filtration effect of the filter structure 40. However, this design is not limited to this. In other embodiments, the filter structure 40 is installed only with the assistance of the mounting groove 123, and / or the filter structure 40 is assembled to the partition plate 12 by a snap-fit ​​structure.

[0060] Optionally, in an embodiment of this utility model, the filter structure 40 is located inside the soundproof cover 30. It can be understood that the filter structure 40 is installed in the filter channel 124 and forms part of the partition plate 12. By moving the filter structure 40 inward away from the water storage area 111, the filtration effect of the filter structure 40 is not affected, and the installation of the soundproof cover 30 on the partition plate 12 is also convenient. The highest position of the filter hole 41 on the filter structure 40 needs to be lower than or equal to the height of the upper surface of the partition plate 12 (which is also the lower surface of the soundproof cover 30) to ensure that all filter holes 41 participate in the filtration of condensate entering the pumping area 112, thereby improving the cleanliness of the condensate entering the pumping area 112 and the water pump 20.

[0061] Please see Figures 6 to 7In an embodiment of this utility model, the air conditioner further includes a vibration damping seat 50, which is installed in the water tank 11 and supported below the water pump 20. In this way, compared to the water pump 20 directly abutting the bottom of the water tank 11 to form a hard connection, the vibration and noise generated by the water pump 20 when it is working are reduced by adding a vibration damping seat 50 below the water pump 20. Combined with the setting of the sound insulation cover 30, this helps to further improve environmental comfort and enhance the user experience.

[0062] Specifically, in an embodiment of this utility model, the water pump 20 includes a pump body 21 and a suction pipe disposed at the bottom of the pump body 21. The vibration damping seat 50 is provided with a mounting cavity 51 and a first clearance hole 52 communicating with the mounting cavity 51. At least part of the bottom of the pump body 21 is disposed within the mounting cavity 51. The suction pipe passes through the first clearance hole 52 and communicates with the water tank 11. It can be understood that the bottom contour of the pump body 21 is adapted to the shape of the mounting cavity 51, so that the vibration damping seat 50 can reliably enclose the pump body. The bottom of the pump body 21 provides stable support for the water pump 20 and facilitates the installation of the water pump 20 and the vibration damping seat 50, which are fixed as a whole, into the pumping area 112, thereby improving installation efficiency. The connection between the pump body 21 and the vibration damping seat 50 can be made of various methods, including but not limited to interference fit, snap fit, and adhesive bonding. The vibration damping seat 50 has good vibration absorption and noise reduction performance and can be made of vibration damping materials such as rubber and silicone, or contain vibration damping structures such as springs to absorb and disperse the vibration and abnormal noise generated by the water pump 20.

[0063] During the installation of the pump body 21 into the mounting cavity 51, the vibration damping seat 50 is provided with a first clearance hole 52 that connects to the mounting cavity 51. The suction pipe at the bottom of the pump body 21 passes through the first clearance hole 52, so that the suction pipe is connected to the water pumping area 112 of the water tank 11. This facilitates the water pump 20 to draw water from the water pumping area 112 through the suction pipe, thereby realizing the discharge of condensate on the chassis 10.

[0064] Furthermore, in order to discharge the water pumped by the pump body 21, a drain pipe 22 is also connected to the side of the pump body 21. The vibration damping seat 50 is also provided with a second clearance hole 53 that connects to the mounting cavity 51. The drain pipe 22 passes through the second clearance hole 53 and extends along the water pipe groove 121 to extend out of the pumping area 112. In order to facilitate the installation and removal of the drain pipe 22, the vibration damping seat 50 is also provided with an installation notch 54 that extends from the edge of the cavity opening of the mounting cavity 51 toward the bottom of the mounting cavity 51. The installation notch 54 connects to the second clearance hole 53, so that the drain pipe 22 can pass through the installation notch 54 and be installed in the second clearance hole 53, or the second clearance hole 53 is formed at the edge of the cavity opening of the mounting cavity 51, or the second clearance hole 53 and the first clearance hole 52 are the same hole structure.

[0065] In addition, the outer periphery of the pump body 21 is provided with mounting feet 23, which are connected to the chassis 10. Specifically, the chassis 10 is provided with mounting posts, which can be set on the partition plate 12. The mounting feet 23 are placed on the mounting posts and are relatively fixed by means of screw connection, pin fixing, snap-fit ​​connection, etc. With the support of the vibration damping seat 50 at the bottom of the pump body 21, the water pump 20 is stably assembled on the chassis 10.

[0066] Please see Figure 7 In an embodiment of this utility model, the vibration damping seat 50 is installed on the water tank 11 by the support foot 55 at its bottom to raise the bottom of the vibration damping seat 50. In this way, the bottom of the water tank 11 can be contacted with a smaller contact surface, so that the chassis 10 can support the water pump 20 through the vibration damping seat 50, while reducing the transmission of vibration to the chassis 10.

[0067] Multiple support feet 55 may be provided, extending from the bottom center of the vibration damping seat 50 to its outer edge. Three support feet 55 are evenly arranged along the circumference of the vibration damping seat 50 to form a stable triangular support structure, effectively resisting lateral thrust and torque. Alternatively, in other embodiments, the support feet 55 may be columnar, or the chassis 10 may have support ribs that abut against the bottom of the vibration damping seat 50.

[0068] Optionally, in an embodiment of this utility model, the air conditioner includes an indoor unit and an outdoor unit, with the chassis 10, the water pump 20, and the soundproof enclosure 30 all located within the indoor unit. The indoor unit and the outdoor unit are connected via a refrigerant hose assembly, which is pre-filled with refrigerant. Specifically, the air conditioner of this utility model can be a split-type air conditioner that facilitates individual installation by the user. It uses a refrigerant hose assembly to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. Thus, when the user installs the equipment themselves, they only need to fix the indoor and outdoor units separately, without needing to assemble refrigerant pipes or add refrigerant, thereby reducing installation difficulty and enabling individual installation. However, this design is not limited to this. In other embodiments, the air conditioner of this utility model can also be a common split-type air conditioner or a portable air conditioner.

[0069] Optionally, in an embodiment of this utility model, the compressor of the air conditioner is located in the indoor unit, which can reduce the weight of the outdoor unit and facilitate its installation. For example, users can move the outdoor unit themselves to find a suitable installation location, reducing installation difficulty and labor costs, especially in areas where labor costs are high. Correspondingly, the compressor is also equipped with a noise reduction structure to ensure low-noise operation of the indoor unit, and a buffer structure is also provided to reduce compressor vibration transmission.

[0070] Optionally, in an embodiment of this utility model, the bottom of the indoor unit is provided with casters to facilitate the movement and transport of the indoor unit; correspondingly, the indoor unit is provided with a locking structure to constrain the rotation of the casters, ensuring stable operation of the indoor unit.

[0071] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
