[0036] In order to make the purpose, technical solutions and advantages of this application clearer, the following part will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0037] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0038] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, in the description of this application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0040] The present application proposes a HVAC equipment. In the embodiment of the present application, the HVAC equipment includes but is not limited to air conditioners, multi-split units, heat pumps and other equipment, and can be used in large-scale places such as shopping malls and office buildings. Among them, the HVAC equipment may include an indoor unit, an outdoor unit (not shown in the figure) and a connecting pipe (not shown in the figure). The indoor unit is connected to the outdoor unit through a connecting pipe so that the indoor unit and the outdoor unit form a circulation flow path. In some actual use scenarios, the indoor unit of the present application can be installed indoors, the outdoor unit is responsible for cooling or heating, and transports refrigerant through the connecting pipe. The refrigerant exchanges heat with the indoor air and the outdoor air respectively, and the indoor unit is responsible for transporting cold air or hot air to the room to achieve the effect of cooling or heating.

[0041] Among them, the indoor unit can include a ceiling unit, a duct unit or a wall-mounted air-conditioning indoor unit, etc. Among them, the ceiling unit is usually embedded in the ceiling in the form of a suspended ceiling, so that the ceiling unit can be hidden through the ceiling. In this way, the ceiling unit has a better hiding effect and is more beautiful than other indoor units.

[0042] During cooling operation, the indoor unit generates a large amount of condensed water. To prevent the slow condensed water discharge efficiency from causing excessive condensed water accumulation inside the indoor unit, a water pump is typically installed in the indoor unit to improve the condensed water discharge efficiency. The water pump is typically connected to a mounting bracket, which is then fixed to the indoor unit via the mounting bracket. In related art, multiple screws are typically used to align and secure the various support legs of the water pump to the mounting bracket. However, this installation process is time-consuming and inefficient. Therefore, further improvements are necessary.

[0043] 1 to 3 , the indoor unit 1000 of the present application includes a body 200 and a water pump assembly 100 , which is disposed in the body 200 . The water pump assembly 100 includes a mounting bracket 10 , a water pump 20 , and a fixing member 30 .

[0044] The mounting bracket 10 can be detachably secured to the inner wall of the housing 200 by screws or snap-fit ​​connections. As the main support for the water pump assembly 100, the mounting bracket 10 can be made of metal, which offers advantages such as high strength and corrosion resistance, ensuring stability. Alternatively, the mounting bracket 10 can be made of plastic, which offers advantages such as light weight and an aesthetically pleasing appearance, thereby reducing the overall weight of the indoor unit 1000.

[0045] The water pump 20 includes a pump body 22 and a plurality of support legs 21. The plurality of support legs 21 can be directly connected to the bottom of the pump body 22, or the plurality of support legs 21 can be connected to the same base, which is then connected to the pump body 22. The number of support legs 21 can be two, three, four, etc., and they are spaced apart along the bottom of the pump body 22. Increasing the number of support legs 21 improves the stability of the pump body 22. The pump body 22 is provided with a water inlet interface 221 and a water outlet interface 222. The water inlet interface 221 is connected to the water receiving tray of the indoor unit 1000, while the water outlet interface 222 is connected to the outside of the indoor unit 1000 via a pipeline, thereby achieving the goal of pumping the condensed water in the water receiving tray to the outside of the indoor unit 1000.

[0046] The fixing member 30 is detachably connected to the mounting bracket 10. It is understood that during the initial assembly process, the fixing member 30 is connected to the mounting bracket 10, thereby clamping and fixing the multiple support legs 21. Specifically, the fixing member 30 and the mounting bracket 10 apply pressure to the upper and lower surfaces of the support legs 21, respectively, to secure the fixing member 30, the mounting bracket 10, and the water pump 20 relative to each other. When the water pump 20 is subsequently repaired or replaced, and the water pump 20 needs to be separated from the mounting bracket 10, the fixing member 30 and the mounting bracket 10 can be disassembled to remove the support legs 21 of the water pump 20. The fixing member 30 is provided with an interface identifier 34, which can be positioned relative to the water outlet interface 222 to further improve assembly efficiency.

[0047] The above-mentioned setting can avoid the use of the traditional screw alignment connection method between the multiple support legs 21 of the water pump 20 and the mounting bracket 10, and there is no need to open screw holes on the support legs 21. It not only improves the structural strength of the support legs 21, but also eliminates the screw hole alignment process between the support legs 21 and the mounting bracket 10, reduces the number of screws used, reduces material costs, solves the problem of assembly difficulty between the water pump 20 and the mounting bracket 10, shortens the assembly time, and improves the assembly efficiency of the water pump 20 and the mounting bracket 10, thereby further improving the overall performance of the indoor unit 1000.

[0048] 4 and 5 , in some structural forms, the mounting bracket 10 and the fixing member 30 cooperate to define a fixing groove 30a, and the support leg 21 is at least partially fixed in the fixing groove 30a. By forming the fixing groove 30a to limit the support leg 21, the support leg 21 is limited by the groove wall, which increases the force contact area between the mounting bracket 10, the fixing member 30, and the support leg 21, thereby improving the limiting effect of the multiple support legs 21, and further enhancing the limiting effect on the water pump 20. It should be noted that the fixing groove 30a can be defined only by a recessed groove on the surface of the mounting bracket 10 facing the fixing member 30, thereby avoiding the need for a groove in the fixing member 30, thereby improving the structural strength of the fixing member 30. Alternatively, the fixing groove 30a can be defined only by a recessed groove on the surface of the fixing member 30 facing the mounting bracket 10, thereby avoiding the need for a groove in the mounting bracket 10, thereby improving the structural strength of the mounting bracket 10. Alternatively, grooves may be formed on the relative surfaces of the mounting bracket 10 and the fixing member 30 to cooperate in defining the fixing groove 30a, so as to simultaneously increase the force contact area between the mounting bracket 10 and the fixing member 30 and the support foot 21, so as to reduce the excessive difference in force between the mounting bracket 10 and the fixing member 30 clamping the support foot 21, and balance the service life of the two.

[0049] Furthermore, a plurality of fixing grooves 30a are provided, and a supporting foot 21 is fixed to a fixing groove 30a. The sidewall of each fixing groove 30a can be provided in an arc shape to improve the safety during installation. By forming a plurality of independently provided fixing grooves 30a to respectively correspond to and fix a plurality of supporting feet 21, the force contact area of ​​each supporting foot 21 when being clamped is further increased, and each supporting foot 21 is not easy to move after being clamped, so as to further improve the limiting stability of the plurality of supporting feet 21. In other embodiments, the fixing groove 30a can also be an annular through groove, so that the annular through groove is provided in an annular shape along the outer peripheral extension direction of the fixing member 30. When the fixing member 30 and the mounting bracket 10 are connected, the annular through groove can cover a plurality of supporting feet 21 at the same time, which not only facilitates processing, but also eliminates the independent alignment process of the plurality of supporting feet 21, so as to further improve the assembly efficiency.

[0050] Referring to Figures 4 and 5 , in some structural configurations, the water pump assembly 100 further includes a buffer member 40 disposed between the support leg 21 and the wall of the fixing groove 30a. The buffer member 40 is preferably made of a soft material, such as a foam material or sponge material. The buffer member 40 may also be made of a soft, elastic material, although this embodiment is not limited thereto. By disposing the buffer member 40 between the support leg 21 and the wall of the fixing groove 30a, the buffer member 40 isolates the support leg 21 from the fixing member 30 and the mounting bracket 10, thereby preventing rigid contact between the support leg 21, the fixing member 30, and the mounting bracket 10, thereby ensuring the service life of the fixing member 30, the mounting bracket 10, and the support leg 21. Furthermore, the buffer member 40 can also act as a buffer against vibrations generated during operation of the water pump 20, helping to reduce vibration and impact of the support leg 21 on the mounting bracket 10 and the fixing member 30, further improving the structural stability of the water pump assembly 100.

[0051] Furthermore, the buffer member 40 is mounted on the portion of the support leg 21 located within the fixing groove 30a. Thus, the buffer member 40 is mounted around the circumference of the support leg 21 to increase the contact area with the support leg 21, thereby improving the stability of the connection between the buffer member 40 and the support leg 21, making it difficult for the buffer member 40 to separate from the support leg 21, thereby ensuring the buffer member 40's cushioning effect on the support leg 21.

[0052] 4 , in some structural forms, the fixing member 30 is provided with one of a snap-fit ​​protrusion 33 and a snap-fit ​​recess 14, and the mounting bracket 10 is provided with the other of the snap-fit ​​protrusion 33 and the snap-fit ​​recess 14. The snap-fit ​​protrusion 33 and the snap-fit ​​recess 14 are correspondingly snap-fitted to relatively fix the fixing member 30 and the mounting bracket 10. Compared with other fixing forms such as threaded connection, the snap-fit ​​fixing form does not require the provision of additional fixing connectors, making the connection between the fixing member 30 and the mounting bracket 10 easier for staff to operate and improving the assembly efficiency of both. Specifically, the snap-fit ​​protrusion 33 can be a bump, and the snap-fit ​​recess 14 can be a through hole or a groove. In this way, by bringing the fixing member 30 and the mounting bracket 10 relatively close together and allowing the bump to be inserted into the through hole or groove, the bump is limited in directions other than the insertion direction, thereby achieving relative fixation of the fixing member 30 and the mounting bracket 10. The number of the engaging protrusion 33 and the engaging recess 14 can both be set to a single one to simplify the structure of the fixing member 30 and the mounting bracket 10. Of course, the number of the engaging protrusion 33 and the engaging recess 14 can also be set to multiple, with multiple engaging protrusions 33 corresponding to multiple engaging recesses 14. In this way, by providing multiple engaging protrusions 33 and multiple engaging recesses 14, the stability of the relative fixation between the fixing member 30 and the mounting bracket 10 is improved.

[0053] Furthermore, the mounting bracket 10 includes a connected support portion 11 and a connecting portion 12, which are arranged at an angle. The connecting portion 12 is connected to a snap-on recess 14. The support portion 11 and connecting portion 12 can be arranged in an L-shape and are both connected to the inner wall of the indoor unit 1000's body 200. This improves the stability of the mounting bracket 10, preventing the water pump 20 and fixing member 30 from wobbling relative to the body 200 during use, further enhancing the reliability of the indoor unit 1000. The joint between the support portion 11 and connecting portion 12 is smoothly transitioned. This creates a more aesthetically pleasing joint and prevents scratches from being caused by the installer or user. The support portion 11 and connecting portion 12 are integrally formed. That is, the support portion 11 and the connecting portion 12 can be made into an integral structure by stamping a plate. In this way, the number of parts in the mounting bracket 10 can be reduced, making the overall structure of the mounting bracket 10 simpler and the overall structure of the mounting bracket 10 stronger.

[0054] In conjunction with Figures 2 to 4, the water pump assembly 100 further includes a water level switch 80. The main function of the water level switch 80 is to monitor and control the degree of accumulation of condensed water. That is, when the condensed water reaches a certain water level, the water level switch 80 will be triggered, and a signal will be sent to notify the start of the water pump 20 to suck the condensed water to prevent the condensed water from overflowing, avoid water leakage accidents indoors, and improve the safety of the indoor unit 1000. The mounting bracket 10 also includes an extension 13, which is connected to the top of the support part 11 and extends toward the outside of the support part 11. The extension 13 can be an integral structure with the support part 11, so as to improve the structural strength of the extension 13. At the same time, the extension 13 extends toward the outside of the support part 11 to avoid the extension 13 interfering with the water pump 20 located on the support part 11. The water level switch 80 is detachably connected to the extension 13 , so that the water pump 20 and the water level switch 80 can be integrated into the supporting member at the same time, so as to facilitate electrical connection between the water pump 20 and the water level switch 80 .

[0055] The fixing member 30 includes a main body 31 and a stopper 32 connected to each other, with a snap-fitting protrusion 33 connected to the stopper 32. The main body 31 and the stopper 32 can also be arranged at an angle. During installation, the stopper 32 and the support portion 11 are relatively close to each other for abutment and positioning, so that the main body 31 and the support portion 11 are arranged opposite each other. The main body 31 has an escape opening 312, which allows the pump body 22 to pass through the escape opening 312. The escape opening 312 is then connected to the snap-fitting recess 14 via the snap-fitting protrusion 33, so that the main body 31 and the support portion 11 clamp and fix the multiple support legs 21. This abutment and positioning of the stopper 32 and the alignment of the escape opening 312 improve the connection efficiency between the fixing member 30 and the mounting bracket 10 and enhance the accuracy of installation.

[0056] 6 , further, the main body 31 is provided with a first connection hole 311, and the support portion 11 is provided with a second connection hole 111. The water pump assembly 100 further includes a fastener 50, which passes through the first connection hole 311 and the second connection hole 111 in sequence to fix the main body 31 and the support portion 11 relative to each other. The first connection hole 311 and the second connection hole 111 can be threaded holes, and the fastener 50 can be a screw. The main body 31 and the support portion 11 are fixed together using screws. This fixing method is relatively simple to install and easy to disassemble, facilitating subsequent maintenance and can further improve the stability of the main body 31 and the support portion 11 clamping and fixing the support leg 21. Of course, in other embodiments, the main body 31 and the support portion 11 can also be fixed together using commonly used connection methods in the field, such as pin connection and rivet connection.

[0057] 7 and 8 , to enhance the versatility of the water pump assembly 100, the water pump assembly 100 further includes a first wire-fixing member 60 and a second wire-fixing member 70. Both the first wire-fixing member 60 and the second wire-fixing member 70 are connected to the fixing member 30. The first wire-fixing member 60 is used to secure the power harness, while the second wire-fixing member 70 is used to secure the weak-wire harness. The provision of the first wire-fixing member 60 and the second wire-fixing member 70 allows the power harness and the weak-wire harness to be routed separately, preventing electromagnetic interference from the power harness on the weak-wire harness. This improves the reliability of signal transmission within the weak-wire harness and ensures a more orderly routing of the power harness and weak-wire harness. Among them, the strong wire harness is a wire harness with a transmission voltage higher than 110V (such as the power line of the water pump 20 of the indoor unit 1000), and the weak wire harness is a wire harness with a transmission voltage lower than 110V (such as the power line of the display screen of the indoor unit 1000), and the first wire fixing member 60 and the second wire fixing member 70 can be an integrated structure with the fixing member 30. In this way, not only can the fixing effect of the first wire fixing member 60 and the second wire fixing member 70 on the strong wire harness and the weak wire harness be improved, but also the number of assembly parts in the water pump assembly 100 can be reduced, so that the overall structure of the fixing member 30 is simpler and the strength of the overall structure is higher. At the same time, the first wire fixing member 60 and the second wire fixing member 70 can be integrated on the fixing member 30 to increase the function of the water pump assembly 100.

[0058] Optionally, the first and second wire-fixing members 60 and 70 are located on opposite sides of the fixed member 30. This not only facilitates the processing and manufacturing of the first and second wire-fixing members 60 and 70, preventing interference, but also increases the spacing between the power and power harnesses after they are secured. Of course, the present invention is not limited to this arrangement; the first and second wire-fixing members 60 and 70 may not be positioned opposite each other, as long as the minimum distance between them is greater than the safety clearance.

[0059] Optionally, the first wire fixing member 60 includes a first support plate 61 and a first claw 62, both of which are connected to the fixing member 30. The first claw 62 and the first support plate 61 can be spaced apart along the thickness direction of the fixing member 30, and the first claw 62 is located above the first support plate 61. In this way, the first support plate 61 and the first claw 62 are arranged relative to each other to form a first wire fixing space 60a having a first notch 60b. The power harness passes through the first notch 60b and is confined within the first wire fixing space 60a. The first claw 62 can limit the upper side of the power harness, while the first support plate 61 can limit the lower side of the power harness, thereby limiting the power harness to be placed centrally and avoiding dispersion. At the same time, the power harness can also be allowed to pass through the first notch 60b and out of the first wire fixing space 60a to facilitate subsequent maintenance and replacement. It should be noted that the end of the first claw 62 facing away from the fixed member 30 and the end of the first support plate 61 facing away from the fixed member 30 can be bent, thereby increasing the contact area of ​​the power harness to enhance the restraining effect on the power harness. In addition, the end of the first support plate 61 forming the first notch 60b can form a guide surface, thereby facilitating the power harness to enter the first fixed wire space 60a more easily through the guidance of the guide surface. The first claw 62 and the first support plate 61 forming the first notch 60b can be arranged away from the fixed member 30, thereby facilitating the installation and removal of the power harness and improving assembly efficiency.

[0060] Optionally, the second wire fixing member 70 includes a second support plate 71 and a plurality of second claws 72, the second support plate 71 and the plurality of second claws 72 are all connected to the fixing member 30, and the plurality of second claws 72 are arranged at intervals, the second support plate 71 is arranged opposite to one of the second claws 72 to form a second wire fixing space 70a having a second notch 70b, and the low-voltage wire harness passes through the second notch 70b and is confined in the second wire fixing space 70a.

[0061] It should be noted that, since the cross-sectional dimensions of the strong electric wire harness are larger than the cross-sectional dimensions of the weak electric wire harness, the second support plate 71 and the plurality of second claws 72 can form a second notch 70b with a dimension smaller than the dimension of the first notch 60b, so that the installer can clearly identify the installation positions of the strong electric wire harness and the weak electric wire harness, thereby improving the installation efficiency. The second claw 72 and the second support plate 71 can be spaced apart along the thickness direction of the fixing member 30, and the second claw 72 is located above the second support plate 71, so that the second claw 72 limits the upper side of the weak electric wire harness, while the second support plate 71 limits the lower side of the weak electric wire harness, thereby limiting the weak electric wire harness to be placed centrally and avoid dispersion. At the same time, the weak electric wire harness can also be passed through the second notch 70b to pass through the second fixed wire space 70a for subsequent maintenance and replacement. It should be noted that the shape of the second clamp can be the same as that of the first clamp to improve production efficiency. The second support plate 71 can be set at an angle, and the position of the end of the second support plate 71 away from the fixed component 30 is higher than the position of the end of the second support plate 71 close to the fixed component 30, so that the weak-wire harness placed on the second support plate 71 can be more concentrated on the end of the second support plate 71 close to the fixed component 30 under the action of gravity, thereby further improving the stability of the weak-wire harness in the second fixed wire space 70a.
