Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] Currently, most mobile air conditioners use water-pumping motors and water wheels to remove condensed water from the indoor unit. Split units discharge condensed water from the indoor unit by hanging it higher. Some use water pumps to pump the condensed water to a high position on the outside, which has high requirements for the water pump head. Therefore, the water pump power is relatively large, and it is necessary to focus on the vibration and noise during the operation of the water pump.

[0034] An existing water pump fixing structure has a relatively simple fixing method. The bottom of the pump body contacts the ribs at the bottom of the water pan (hard connection), and the upper middle part of the pump body is fixed to the water pan with a screw. According to the existing solution, the water pump and the water pan are hard-connected, which is not very stable. The water pump vibrates greatly when working, and collides with the chassis to produce a large noise problem. When using the air conditioner, users will clearly feel the abnormal noise coming from inside the air conditioner, especially when the water pump starts working. Due to the large vibration, the hard contact with the chassis will produce an impact sound. This noise not only affects the user's comfort, but may also interfere with the rest or work of people around them. Users may feel a significant vibration in the air conditioner as a whole or at least in its bottom area. This not only reduces the product experience, but the continuous noise and vibration will significantly reduce user satisfaction with the air conditioner product, affecting the brand image and user loyalty. Long-term vibration may cause the internal components of the air conditioner to loosen and wear faster, thereby increasing the frequency of repairs and replacement parts, and increasing the user's maintenance costs.

[0035] To this end, the utility model proposes a water pump assembly and an air conditioner, which add a vibration damping seat without changing the existing water pump to eliminate the abnormal noise generated when the water pump is working; the vibration damping pad can be delivered together with the water pump assembly, and the materials are received as one, which improves the assembly efficiency of the production line, and the vibration damping seat does not affect the water pumping of the water pump.

[0036] The water pump assembly is used in an air conditioner in which a compressor is arranged in an indoor unit of the air conditioner. The air conditioner includes an indoor unit and an outdoor unit. The refrigerant hose assembly passes through the casing of the air conditioner to connect the indoor unit and the outdoor unit.

[0037] The indoor and outdoor air conditioner units can be integrated into a single unit, making the air conditioner a portable unit that does not require an external exhaust duct or outdoor unit. All components are integrated into a single unit. However, in this embodiment, the indoor and outdoor air conditioner units are connected via a flexible refrigerant pipe. Furthermore, the air conditioner compressor can be located within the indoor unit. This allows for user-installable split-type air conditioners, which utilize flexible refrigerant pipes to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit. Refrigerant is injected into the refrigerant circuit before the unit leaves the factory. This allows users to install the unit themselves by simply securing the indoor and outdoor units separately, eliminating the need to assemble refrigerant pipes or inject refrigerant. This reduces installation complexity and facilitates user-installation.

[0038] Placing the compressor in the indoor air conditioner reduces the weight of the outdoor unit, making it easier for users to move the outdoor unit to a suitable installation location. This reduces installation effort and labor costs, especially in areas with high labor costs. To reduce noise, the indoor unit's compressor is also treated with noise-reducing materials, such as filling it with noise-reducing materials or installing a buffer structure to reduce the transmission of compressor vibration.

[0039] See also Figure 1 , Figure 1 A schematic structural diagram of an embodiment of a water pump assembly 100 provided by the present invention; In an embodiment of the present invention, the water pump assembly 100 includes a water pump 200 and a vibration damping seat 300, referring to Figure 2 The water pump 200 includes a pump body 210 and a water suction pipe 220 provided at the bottom of the pump body 210; Figure 3 and Figure 4 The vibration damping seat 300 is provided with an installation cavity 301 and a first avoidance hole 302 communicating with the installation cavity 301 . The bottom of the pump body 210 is at least partially disposed in the installation cavity 301 , and the water suction pipe 220 passes through the first avoidance hole 302 .

[0040] The technical solution of the present invention effectively reduces the vibration and abnormal noise generated by the operation of the water pump 200 by adding a vibration damping seat 300 without changing the structure of the existing water pump 200. The water suction pipe 220 is provided with a first avoidance hole 302, and the bottom of the pump body 210 is at least partially located in the installation cavity 301. The shape of the installation cavity 301 matches the bottom contour of the pump body 210 to provide stable support and reduce unnecessary shaking. The passage of the water suction pipe 220 through the avoidance hole does not affect the pumping of the water pump 200. The vibration damping seat 300 is made of a material with good shock absorption and sound insulation properties, such as rubber, elastomer, or a specially designed shock-absorbing pad. The water pump 200 and the vibration damping seat 300 are packaged and delivered as a whole component, which can simplify the installation process and improve installation efficiency. The vibration damping seat 300 effectively reduces the vibration and mechanical noise of the water pump 200 during operation, improves environmental comfort, and enhances the user experience.

[0041] The vibration-damping material (such as rubber, springs, etc.) in the vibration-damping seat 300 effectively absorbs and disperses the vibration energy generated by the water pump 200. To ensure that the vibration-damping pad can be delivered as a component with the water pump 200, improving production line assembly efficiency, simplifying the installation process, and improving installation efficiency, in this embodiment, the outer wall of the pump body 210 and the wall of the mounting cavity 301 form an interference fit. This interference fit ensures that the water pump 200 is firmly fixed within the mounting cavity 301, allowing for integrated assembly and improving production line assembly efficiency. In other embodiments, the vibration-damping seat 300 can be secured to the water pump 200 by snapping, gluing, or other methods.

[0042] Further, refer to Figure 1 and Figure 2 The side of the pump body 210 is also provided with a drain pipe 230, and the outer side of the vibration damping seat 300 is also provided with a second avoidance hole 303 communicating with the installation cavity 301. The drain pipe 230 passes through the second avoidance hole 303. The installation cavity 301 on the vibration damping seat 300 covers the bottom of the pump body 210 of the water pump 200. The first avoidance hole 302 and the second avoidance hole 303 of the vibration damping seat 300 are convenient for installing the water pump 200. There is a tight interference fit between the water pump 200 cavity and the pump body 210. In order to facilitate installation, the vibration damping seat 3 00 also has a mounting notch 304 extending downward from the edge of the mounting cavity 301 to connect to the second avoidance hole 303. The drain outlet is installed within the second avoidance hole 303 through the mounting notch 304. To further prevent detachment, the diameter of the mounting notch 304 is smaller than the outer diameter of the drain pipe 230. Together with the surrounding structure of the second avoidance hole 303, the drain pipe 230 forms a relatively stable fixation. The mounting notch 304 can limit the detachment of the drain pipe 230, further preventing it from falling off during transportation and assembly. In other embodiments, the drain pipe 230 can be located above the vibration damping seat 300, that is, the vibration damping seat 300 is installed behind the water pump 200 and below the drain pipe 230, or it can be installed in a manner that avoids the drain pipe 230.

[0043] To ensure smooth assembly, in this embodiment, the inner diameter of the first avoidance hole 302 is larger than the outer diameter of the suction pipe 220, and the inner diameter of the second avoidance hole 303 is larger than the outer diameter of the drainage pipe 230. This allows the suction pipe 220 and drainage pipe 230 to pass smoothly through. Furthermore, the edges of the avoidance holes should be smooth or have a curved transition. For example, the diameter of the installation notch 304 should gradually decrease from top to bottom, providing a guide and reducing friction with the suction pipe 220 and drainage pipe 230, facilitating assembly.

[0044] To ensure that the mounting cavity 301 is sufficiently deep to provide stable support and prevent the water pump 200 from shaking or shifting during operation, the depth of the mounting cavity 301 is 0.25-0.45 times the height of the water pump 200. A deeper mounting cavity 301 increases the contact area between the water pump 200 and the vibration damping base 300, thereby improving stability. An appropriate depth allows the vibration damping material (such as rubber, springs, etc.) in the vibration damping base 300 to effectively absorb and disperse the vibration energy generated by the water pump 200. However, an excessively deep mounting cavity 301 may limit the deformation capacity of the vibration damping material, thereby reducing the vibration damping effect. The depth of the mounting cavity 301 should also take into account the ease of maintenance and repair of the water pump 200. A shallower mounting cavity 301 facilitates the removal and replacement of the water pump 200 while also providing sufficient operating space for technicians to perform inspections and repairs. A depth of 0.25 to 0.45 times the height of the water pump 200 is a well-considered design parameter range. The goal is to achieve stable installation, effective vibration reduction, convenient maintenance and repair, and standardized component design for the water pump 200. In actual application, fine-tuning can be performed to meet specific needs based on factors such as the specific water pump 200 model, specifications, and operating environment.

[0045] Reference Figure 3 and Figure 4To prevent direct contact between the pump body 210 and the water pan, and thus prevent noise during operation, the vibration damping base 300 is provided with support feet 310. These feet 310 contact the outside, leaving the bottom of the vibration damping base 300 suspended relative to the contact surface. The addition of support feet 310 is a clever and practical improvement. These support feet 310 not only directly contact the external contact surface, allowing the bottom of the vibration damping base 300 to remain suspended, but also extend from the outer edge toward the center of the vibration damping base 300, providing a stable foundation for the entire device. Because the support feet 310 suspend the bottom of the vibration damping base 300, they provide a certain degree of vibration isolation. When vibrations generated by the operation of the water pump 200 are transmitted through the vibration damping base 300 to the support feet 310, the relatively small contact area between the support feet 310 and the contact surface and the presence of a certain degree of elasticity (if the material of the support feet 310 allows) absorb and dissipate the vibration energy to a certain extent, thereby reducing the transmission of vibration to the surrounding environment.

[0046] There are multiple supporting legs 310. In this embodiment, refer to Figure 3 and Figure 4 , the support legs 310 extend from the outer edge of the vibration damping seat 300 toward the center; there are three support legs 310, and the three support legs 310 are evenly arranged along the circumference. Selecting three support legs 310 is an economical and effective solution. Three support points are sufficient to form a stable triangular support structure that can effectively resist thrust and torque in the horizontal direction. The three support legs 310 are evenly arranged along the circumference to ensure that the vibration damping seat 300 is subjected to balanced force in all directions. This layout helps to reduce local stress concentration and deformation problems caused by uneven force. Through reasonable quantity selection and layout, it can be ensured that the vibration damping seat 300 and the water pump 200 can maintain a stable operating state under various working conditions. In other embodiments, there are two or more support legs 310, or the support legs 310 at the bottom of the vibration damping seat 300 can also be made in other forms such as columns, or directly supported by reinforcements or columns from the bottom surface of the water pan.

[0047] Reference Figure 3 To prevent the pump body 210 from rotating out of its original position and to avoid direct contact between the water pump 200 and the water pan, the vibration damping base 300 is provided with a stopper 320 on the outer circumference of the mounting cavity 301. The stopper 320 cooperates with the positioning portion of the water pan 400 to limit the vibration damping base 300. The existing water pump 200 is limited in rotation by the ribs on the water pan. Introducing the stopper 320 and its corresponding positioning portion (such as the stopper groove 321 and the stopper rib 410) in the design of the vibration damping base 300 is a practical and innovative solution. This design not only enhances the connection stability between the vibration damping base 300 and the water pan 400, but also further improves the vibration reduction performance and noise elimination of the entire system.

[0048] Reference Figure 3 In this embodiment, the limiting portion 320 is a limiting groove 321 extending axially along the vibration damping base 300. The limiting groove 321 extends axially along the vibration damping base 300 and tightly engages with the limiting rib 410 on the water receiving pan 400. This ensures that the vibration damping base 300 is precisely aligned and secured in the desired position during installation, effectively preventing the pump body 210 of the water pump 200 from rotating or deviating from its original position due to vibration or external forces during operation. The cooperation between the limiting portion 320 and the positioning portion eliminates direct contact between the pump body 210 of the water pump 200 and the water receiving pan 400, creating a gap or flexible connection. This design helps reduce the direct transmission of vibration from the water pump 200 to the water receiving pan 400, thereby lowering the vibration level of the entire system. Furthermore, by reducing rigid contact and collision, it effectively eliminates abnormal noise caused by vibration, improving the smooth operation and noise control of the equipment. This design also simplifies the installation process, reducing installation difficulty and cost.

[0049] In other embodiments, the limiting portion 320 is a convex rib, and the periphery of the vibration damping seat 300 may also be in the form of a convex rib and contact the convex rib, or the groove and the convex rib may be inserted and limited.

[0050] In addition, refer to Figure 1 In order to make the vibration damping seat 300 have a certain height and adapt to different models of water pumps 200, a corresponding shape of avoidance gap 305 can be set according to the different models of water pumps 200 corresponding to the outer convex structure 240 of the water pump 200, such as the plug-in port, heat dissipation cavity, etc. In order to facilitate the bottom of the water pump 200 to be inserted into the vibration damping seat 300, the opening of the avoidance gap 305 faces the cavity opening of the installation cavity 301. After installation, the outer convex structure 240 is set in the avoidance gap 305. Figure 5 The pump body 210 is further provided with a mounting skirt 250 having fixing holes 251. The pump body 210 is locked to the water pump 200 by screws passing through the fixing holes 251. The lower end of the pump body 210 is limited by the vibration damping seat 300 and the water receiving tray 400. In other embodiments, the mounting skirt 250 can also be fixed by providing a buckle or the like.

[0051] In summary, without changing the structure of the existing water pump 200, the vibration and abnormal sound generated by the water pump 200 during operation are effectively reduced by adding the vibration damping seat 300. The water pump 200 and the vibration damping seat 300 are tightly assembled so that the water pump 200 and the vibration damping seat 300 are packaged and delivered as a whole component. For the case where the interference is large, it may be necessary to heat the installation cavity 301 before assembly to expand the aperture for easy installation; after cooling, the aperture shrinks to achieve a tight fit, which can simplify the installation process and improve Installation efficiency; in addition, a support foot 310 is added to the bottom to directly contact the external contact surface, so that the bottom of the vibration damping seat 300 is relatively suspended, providing a stable basic support for the entire device; the vibration damping seat 300 is provided with a limiting portion 320 (such as a limiting groove 321) on the outer peripheral surface of the installation cavity 301, and cooperates with the positioning portion (such as the limiting rib 410) on the water receiving tray 400, which not only enhances the connection stability between the vibration damping seat 300 and the water receiving tray 400, but also further improves the vibration reduction performance and abnormal sound elimination effect of the entire system.
