Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a water pump assembly and an air conditioner. BACKGROUND

[0002] In the daily operation of an air conditioner system, a large amount of condensate water is generated due to the cold-heat exchange process of a heat exchanger. If the condensate water cannot be discharged in time and effectively, it will not only cause adverse conditions such as excessive humidity, mold growth and odor, but also cause damage to indoor decoration materials and furniture. If the condensate water is allowed to accumulate, it may penetrate into the interior of the air conditioner or flow along the connecting pipeline, eventually causing corrosion, electrical failure and even overall performance degradation of the air conditioner.

[0003] In related technologies, a water pan is usually used to collect the condensate water generated by the heat exchanger, and then the condensate water in the water pan is discharged to the outdoor through the suction of the water pump. However, due to the water suction structure of the water pump, the water suction efficiency of the water pump is poor, which easily causes the condensate water and dust in the water pan to deposit, resulting in pipeline blockage, which needs to be further improved. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the purpose of the present application is to provide a water pump assembly and an air conditioner.

[0005] The technical scheme adopted by the present application to solve the above technical problems is as follows:

[0034] In the present application, the word "exemplary" is used to mean "serving as an example, instance, or illustration". Any embodiment described as exemplary in the present application is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is presented to enable any person skilled in the art to make and use the present application. In the following description, for the purposes of explanation, numerous details are set forth in order to provide a thorough understanding. It should be apparent to those skilled in the art that the present application can be practiced without the use of these specific details. In other instances, well known structures and processes are not elaborated in order not to obscure the description of the present application with unnecessary detail. Thus, the present application is not intended to be limited by the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0035] In order to facilitate the understanding of the scheme of the present application, the spline curves and arrows used in the reference signs in the drawings are described as follows: the components indicated by the spline curves without arrows are solid components, i.e. components with solid structures; the components indicated by the spline curves with arrows are virtual components, i.e. components without solid structures.

[0036] Ducted air conditioners are usually installed in the ceiling, and are favored by consumers due to their concealed installation and uniform air outlet. For the condensate water discharge problem of ducted air conditioners, the current common water pump installation schemes mainly include two types: one is to place the water pump inside the ducted air conditioner at the branch side, specifically above the water pan; the other is to use an external method, that is, to install the water pump outside the whole machine, and connect the water pump with the water pan through a pipe.

[0037] For the built-in installation scheme, due to the limited space inside the ducted air conditioner, the installation of the water pump needs to maintain a certain safety distance with other key components such as branch pipes, which increases the design complexity. Under the premise of fixed length of the ducted air conditioner, the addition of the water pump further compresses the layout space of the heat exchanger, which may lead to a decrease in the heat exchanger area, and further affect the refrigeration effect and air outlet of the air conditioning system. In addition, since the water pump is located inside the whole machine, once it needs to be repaired or replaced, a relatively complex disassembly and assembly process will be involved, which increases the difficulty and cost of maintenance.

[0038] For the external installation scheme, since there is no clear specification for the relative height position of the water pump component and the whole machine, some problems may occur in actual application. For example, when the water pump position is relatively high, it may cause the water in the water pan to not be discharged in time, thereby increasing the risk of water flooding. On the contrary, if the water pump position is too low, the long or excessively curved drain pipe may increase the risk of water leakage. In addition, the liquid level switch of the external water pump may be lower than that of the water pan, which may cause false alarm problems in some cases, further affecting the drainage effect and stability of the whole machine.

[0039] In the first aspect, referring to Figure 1 , Figure 2 and Figure 3 , the embodiment of the present application provides a water pump assembly 10. The water pump assembly 10 comprises a water pump bracket 11, which has a sealed cavity 111 and a groove 112, and a connecting hole 113 is arranged between the sealed cavity 111 and the groove 112. The sealed cavity 111 is provided with a water inlet portion 114 on the side away from the connecting hole 113, which is used to communicate with the water pan 20. The groove 112 is provided with a water outlet portion 115 on the side away from the connecting hole 113. The water pump assembly 10 further comprises a water pump body 12 located in the groove 112. The water pump body 12 has a communicating water suction port 121 and a water outlet port 122. The water suction port 121 is located in the connecting hole 113 to isolate the groove 112 and the sealed cavity 111. The water outlet port 122 communicates with the water outlet portion 115.

[0040] The water pump assembly 10 provided by the embodiment of the present application forms a drainage channel through the sequentially connected water receiving tray 20, water inlet portion 114, sealing cavity 111, water suction port 121, water pump body 12, water outlet port 122 and drainage portion 115, and the water pump body 12 and the sealing cavity 111 are communicated through the connecting hole 113, the groove 112 and the sealing cavity 111 are isolated, and the sealing cavity 111 is in a relatively sealed state. When the heat exchanger generates condensate water and the condensate water is accumulated in the water receiving tray 20, the water pump assembly 10 starts to work, and after the water pump body 12 starts to operate, a negative pressure state is formed in the sealing cavity 111 compared to the area of the water receiving tray 20 through the suction effect of the water pump body 12. The generation of the negative pressure state ensures that the condensate water in the water receiving tray 20 can be smoothly and efficiently sucked into the sealing cavity 111, and then the condensate water enters the water pump body 12 through the water suction port 121, is pressurized under the action of the water pump body 12, and is discharged to the drainage portion 115 through the water outlet port 122, and finally is discharged out of the system. The water pump assembly 10 provided by the present application reduces the deposition of condensate water, dust and other impurities in the water receiving tray 20 and the drainage channel, keeps the water receiving tray 20 and the drainage channel clean, ensures the smoothness of the drainage channel, and effectively avoids the blockage of the drainage channel. The water pump assembly 10 provided by the present application has simple structure, is easy to maintain, is convenient to manufacture, and is economical and efficient.

[0041] It can be understood that the sealing cavity 111 provides a certain water holding space, so that the condensate water in the water receiving tray 20 can flow to the sealing cavity 111 first, and then be discharged through the water pump body 12, thereby avoiding the accumulation of a large amount of condensate water in the water receiving tray 20 when the water pump body 12 is not working, and preventing the condensate water from overflowing, wetting and damaging other components in the air conditioner 100, and soaking the heat exchanger to reduce the heat exchange performance of the heat exchanger.

[0042] In some embodiments of the present application, the groove 112 is adapted to the shape of the water pump body 12, so that the groove 112 can effectively support and fix the water pump body 12.

[0043] It should be noted that the sealing cavity 111 has a cylindrical structure, the top of the sealing cavity 111 is recessed to form the groove 112, in other words, the outer side wall of the sealing cavity 111 is the inner side wall of the groove 112, so that the volume of the water pump assembly 10 can be effectively reduced, the occupied space of the water pump assembly 10 is reduced, and the water pump body 12 is located in the middle and upper part of the water pump support 11, which is conducive to the suction of the condensate water in the sealing cavity 111 to the outside of the drainage portion 115.

[0044] In some embodiments of the present application, the water pump bracket 11 further comprises a first sealing ring 13, two sides of the first sealing ring 13 abutting against the inner wall of the connecting hole 113 and the outer wall of the water suction port 121 respectively. It can be understood that the first sealing ring 13 is located between the connecting hole 113 and the water suction port 121, and the arrangement of the first sealing ring 13 isolates the sealing cavity 111 and the groove 112, improves the sealing performance of the sealing cavity 111, avoids the condensed water in the sealing cavity 111 from overflowing through the connecting hole 113 to the groove 112 and then from the groove 112 to the outdoor to affect the user experience, and the first sealing ring 13 can ensure that the condensed water is smoothly discharged along the channel of the water suction port 121, the water pump body 12 and the water outlet 122.

[0045] Further, the material of the first sealing ring 13 can be silica gel. Silica gel has good elasticity and adhesion, and can fully fill the gap between the water suction port 121 of the water pump body 12 and the connecting hole 113 through thermal expansion and cold contraction, thereby improving the water pumping efficiency of the water pump body 12.

[0046] In some embodiments of the present application, please refer to Figure 2 and Figure 3 , the drainage part 115 is provided with a water leakage hole 1153, and the water leakage hole 1153 communicates the drainage part 115 and the sealing cavity 111.

[0047] Further, the drainage part 115 comprises a drainage groove 1151 and a drainage pipe 1152 located in the drainage groove 1151, the drainage pipe 1152 and the water outlet 122 are communicated, and the water leakage hole 1153 is arranged on the drainage groove 1151. It should be noted that during the operation of the water pump assembly 10, the drainage part 115 extends in a vertically upward direction, wherein the water outlet 122 of the water pump body 12 is communicated with the drainage pipe 1152, so that the condensed water is discharged along the water outlet 122 and the drainage pipe 1152, and the water outlet 122 and the drainage pipe 1152 are sealingly connected to avoid water leakage. By arranging the water leakage hole 1153, when the drainage pipe 1152 leaks, the leaked condensed water flows downward into the drainage groove 1151 under the action of gravity, and then flows into the sealing cavity 111 through the water leakage hole 1153, thereby avoiding the leaked condensed water from dripping into the indoor to affect the user experience.

[0048] Further, the diameter of the water leakage hole 1153 can be set to be relatively small, so that when there is no water leakage, the sealing cavity 111 presents an approximately closed area as much as possible, which is conducive to forming a negative pressure state to make the water pump body 12 suck the condensed water.

[0049] In a second aspect, the embodiments of the present application also provide an air conditioner 100, which comprises a water collecting tray 20 and the above-mentioned water pump assembly 10, and the water inlet part 114 communicates with the water collecting tray 20.

[0050] In some embodiments of the present application, the air conditioner 100 further comprises a heat exchanger located above the water pan 20. The heat exchanger adjusts the indoor temperature through heat exchange, and the condensed water generated during the operation of the heat exchanger can drip into the water pan 20.

[0051] In some embodiments of the present application, referring to Figure 4 and Figure 5 , the horizontal height of the sealed cavity 111 is lower than the horizontal height of the water pan 20. It should be noted that the horizontal height refers to the altitude of the sealed cavity 111 and the water pan 20 during use of the air conditioner 100.

[0052] Specifically, the highest point of the sealed cavity 111 can be 1.5 mm lower than the highest point of the water pan 20, and the lowest point of the sealed cavity 111 can be 7.5 mm lower than the lowest point of the water pan 20. In this way, the water in the water pan 20 will automatically flow into the sealed cavity 111 under the action of gravity, and then be pumped to the outside. When the water pump body 12 fails, the water in the water pan 20 will still flow to the sealed cavity 111, and the water level in the sealed cavity 111 will gradually rise to overflow from the water pump bracket 11, thereby avoiding the accumulation of condensed water in the water pan 20, the rise of the water level, and the soaking of the heat exchanger, which affects the operation of the heat exchanger.

[0053] In some embodiments of the present application, the water pan 20 is provided with an external pipe 21, and the water inlet portion 114 comprises a water inlet pipe in communication with the external pipe 21. Specifically, the side wall of the water pan 20 extends outward to lead out the external pipe 21, which is used to drain the condensed water in the water pan 20 to the water inlet pipe.

[0054] Further, the external pipe 21 is provided with a second sealing ring 211 on the circumferential side, and the water inlet pipe is sleeved on the outside of the external pipe 21, and the second sealing ring 211 connects the external pipe 21 and the water inlet pipe. The water inlet pipe can be a hard water pipe to ensure a certain strength. The second sealing ring 211 can be an O-shaped sealing ring, and the water inlet pipe is axially sleeved on the outside of the external pipe 21 and is pushed in until the external pipe 21 engages with the O-shaped sealing ring. The O-shaped sealing ring can fill the gap between the water inlet pipe and the external pipe 21, thereby improving the sealing performance between the water pan 20 and the water pump bracket 11.

[0055] In some embodiments of the present application, multiple second sealing rings 211 can be provided to further improve the sealing performance and prevent the condensed water from leaking from the water pan 20 to the water pump bracket 11. The provision of the second sealing ring 211 can eliminate the need for pipe clamps or wire ties, thereby achieving reliable installation of the water inlet pipe and the external pipe 21 and facilitating maintenance by after-sales personnel. In addition, the second sealing ring 211 can also provide radial positioning for the connection of the water inlet pipe.

[0056] In some embodiments of the present application, referring to Figure 6The air conditioner 100 further comprises a shell 30 defining a containing cavity 31, and the shell 30 is provided with an air return port 32, and the water pump assembly 10 is located in the containing cavity 31 and is arranged close to the air return port 32.

[0057] In some embodiments of the present application, the air conditioner 100 can be a ducted type air conditioner, and the air return port 32 is arranged at the bottom of the ducted type air conditioner. In other words, the bottom of the water pump assembly 10 is located at the air return port 32. It should be noted that at this time, the external connecting pipe 21 on the water collecting tray 20 can pass through the partition plate in the containing cavity 31 to enter the containing cavity 31 on the side close to the air return port 32, so as to be connected to the water inlet portion 114 on the water pump support 11.

[0058] In this way, when the water pump assembly 10 is installed, it can be directly installed after the air return grille at the air return port 32 is removed, and the water pump assembly 10 can be installed and maintained using the air return port 32, without the need to open a special maintenance opening in the ceiling below the side of the ducted type air conditioner; at the same time, the water pump assembly 10 does not occupy the horizontal space of the ducted type air conditioner, and under the same width of the ducted type air conditioner, the size of the heat exchanger can be larger, effectively increasing the air volume and capacity efficiency of the heat exchanger; in addition, the water pump assembly 10 is installed above the air return port 32, and in the case of damage or water leakage of the water pump assembly 10, the condensate water will leak into the air return port 32 or drip from the air return port 32 to remind the user, effectively preventing the condensate water from flowing back to the ceiling to cause the ceiling to be flooded.

[0059] In some embodiments of the present application, referring to Figure 7 The water pump support 11 is provided with a first connecting portion, and the bottom wall of the air conditioner 100 is provided with a second connecting portion 33, and the first connecting portion and the second connecting portion 33 are fixedly connected. Specifically, the first connecting portion and the second connecting portion 33 can both be screw through holes, and the screw through holes on the water pump support 11 and the bottom wall of the air conditioner 100 are connected by screws, so as to fix the water pump assembly 10 in the air conditioner 100, and the bottom wall of the air conditioner 100 can support and fix the water pump assembly 10.

[0060] In some embodiments of the present application, the side wall of the air conditioner 100 is provided with a drainage connector 34, and the drainage portion 115 is communicated with the drainage connector 34. It should be noted that the drainage connector 34 penetrates through the side wall of the air conditioner 100, and the water pump assembly 10 is located close to the side wall of the shell 30 in the containing cavity 31, so as to facilitate the condensate water to be discharged out of the containing cavity 31 of the air conditioner 100 through the drainage portion 115 and the drainage connector 34.

[0061] The water pump assembly 10 provided by the application, when installed on the air conditioner 100, first installs the water pump body 12 in the groove 112 of the water pump support 11, and isolates the groove 112 and the sealing cavity 111 through the first sealing ring 13, so as to improve the sealing performance of the sealing cavity 111; remove the return air grille at the bottom of the air conditioner 100, insert the water pump assembly 10 into the containing cavity 31 of the air conditioner 100 from the return air port 32, align the water inlet pipe interface of the water pump support 11 with the external connecting pipe 21 on the water receiving disc 20, and then insert along the axial direction, and then position and engage through the second sealing ring 211; then adjust the screw through hole at the bottom of the water pump support 11 to be aligned with the screw through hole of the bottom wall of the air conditioner 100, and screw in a screw to fix the water pump assembly 10 in the containing cavity 31; then connect the drain pipe 1152 on the water pump assembly 10 to the drain connector 34 pre-installed on the side wall of the air conditioner 100, and the installation is completed. The condensate water generated by the operation of the heat exchanger can be sequentially discharged through the water receiving disc 20, the external connecting pipe 21, the water inlet pipe, the sealing cavity 111, the water suction port 121, the water pump body 12, the water outlet port 122, the drain pipe 1152 and the drain connector 34, so as to avoid the deposition of the condensate water to affect the operation of the air conditioner 100, improve the reliability of the air conditioner 100, and improve the disassembly and assembly efficiency of the water pump assembly 10.
