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

[0037] When the following description refers to the 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 only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0038] In the description of the present 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 the present application can be understood according to the specific circumstances. In addition, in the description of the present 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 objects associated before and after are in an "or" relationship.

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

[0040] The present application proposes a HVAC device. In the embodiment of the present application, the HVAC device 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 device 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 a 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] The indoor unit will produce a large amount of condensed water during cooling operation. In order to prevent the slow condensed water discharge efficiency from causing excessive condensed water accumulation in the indoor unit, a water pump is usually installed in the indoor unit to improve the condensed water discharge efficiency. The water pump is generally connected to a mounting bracket and then fixed in the indoor unit through the mounting bracket. In the related art, multiple screws are usually used to align and fix each support leg of the water pump to the mounting bracket, but the installation process is time-consuming and inefficient. Therefore, it is necessary to make further improvements.

[0043] To solve the above problems, refer to Figures 1 to 3 The indoor unit 1000 of the present application includes a body 200 and a water pump assembly 100, and the water pump assembly 100 is arranged 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 fixed to the inner wall surface of the body 200 by a detachable method such as screw connection or snap connection. The mounting bracket 10 serves as the supporting body of the water pump assembly 100, so the mounting bracket 10 can be made of metal to have advantages such as high strength and good corrosion resistance to ensure the stability of the mounting bracket 10. Of course, the mounting bracket 10 can also be made of plastic to make the mounting bracket 10 have advantages such as light weight and beautiful appearance to reduce the overall weight of the indoor unit 1000.

[0045] The water pump 20 includes a pump body 22 and a plurality of supporting legs 21. The plurality of supporting legs 21 can be directly connected to the bottom of the pump body 22, or the plurality of supporting legs 21 can be connected to the same base, and then connected to the pump body 22 by the base. The number of the supporting legs 21 can be two, three, four, etc., and they are arranged at intervals along the bottom of the pump body 22. The stability of supporting the pump body 22 is improved by increasing the number of supporting legs 21. 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 pan of the indoor unit 1000, and the water outlet interface 222 is connected to the outside of the indoor unit 1000 through a pipeline, so as to realize the suction of the condensed water at the water receiving pan to the outside of the indoor unit 1000.

[0046] The fixing member 30 is detachably connected to the mounting bracket 10. It is understandable that in the early assembly process, by connecting the fixing member 30 to the mounting bracket 10, the fixing member 30 and the mounting bracket 10 clamp and fix multiple supporting feet 21, that is, the fixing member 30 and the mounting bracket 10 apply pressure to the upper surface and the lower surface of the supporting feet 21 respectively, so that the fixing member 30, the mounting bracket 10 and the water pump 20 are relatively fixed. When the subsequent maintenance and replacement process is carried out, that is, when the water pump 20 needs to be separated from the mounting bracket 10, it is only necessary to disassemble the fixing member 30 and the mounting bracket 10 so that the supporting feet 21 of the water pump 20 are no longer clamped and fixed, and then the water pump 20 can be separated from the mounting bracket 10. The fixing member 30 is provided with an interface mark 34, and the interface mark 34 can be arranged relative to the water outlet interface 222, so as to further improve the assembly efficiency.

[0047] The above-mentioned setting can avoid the use of the traditional screw alignment connection method between the multiple supporting feet 21 of the water pump 20 and the mounting bracket 10, and there is no need to open screw holes on the supporting feet 21. Not only the structural strength of the supporting feet 21 is improved, but also the screw hole alignment process of the supporting feet 21 and the mounting bracket 10 is omitted, the number of screws used is reduced, the material cost is reduced, the problem of assembly difficulty between the water pump 20 and the mounting bracket 10 is solved, the assembly time is shortened, and the assembly efficiency of the water pump 20 and the mounting bracket 10 is improved, thereby further improving the overall performance of the indoor unit 1000.

[0048] Reference Figure 4 and Figure 5 In some structural forms, the mounting bracket 10 and the fixing member 30 cooperate to define a fixing groove 30a, and the support foot 21 is at least partially fixed in the fixing groove 30a. In this way, by forming the fixing groove 30a to limit the support foot 21, the support foot 21 is limited by the groove wall, that is, the force contact area between the mounting bracket 10 and the fixing member 30 and the support foot 21 is increased, thereby improving the limiting effect of multiple support feet 21, so as to further improve the limiting effect on the water pump 20. It should be noted that the fixing groove 30a can be defined only by forming a groove body on the surface of the mounting bracket 10 facing the fixing member 30, so as to avoid the groove setting of the fixing member 30, thereby improving the structural strength of the fixing member 30. Alternatively, the fixing groove 30a can be defined only by forming a groove body on the surface of the fixing member 30 facing the mounting bracket 10, so as to avoid the groove setting of the mounting bracket 10, thereby improving the structural strength of the mounting bracket 10. Alternatively, the relative surfaces of the mounting bracket 10 and the fixing member 30 may both form a groove body to cooperate to define the fixing groove 30a, so as to simultaneously increase the force contact area of ​​the mounting bracket 10 and the fixing member 30 with the supporting foot 21, so as to reduce the excessive difference in force between the mounting bracket 10 and the fixing member 30 clamping the supporting foot 21, so as to 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 groove side wall of each fixing groove 30a can be provided in an arc surface 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, so that 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 is not only convenient for processing, but also saves the independent alignment process of a plurality of supporting feet 21, so as to further improve the assembly efficiency.

[0050] Reference Figure 4 and Figure 5 In some structural forms, the water pump assembly 100 further includes a buffer 40, which is arranged between the support foot 21 and the groove wall in the fixing groove 30a. The buffer 40 can be preferably made of a soft material, such as a foam material, a sponge material, etc. The buffer 40 can also be made of a soft and elastic material, but the present embodiment is not limited thereto. By arranging the buffer 40 between the support foot 21 and the groove wall in the fixing groove 30a, the buffer 40 can isolate the support foot 21 from the fixing member 30 and the mounting bracket 10, thereby avoiding the rigid abutment between the support foot 21 and the fixing member 30 and the mounting bracket 10, so as to ensure the service life of the fixing member 30, the mounting bracket 10 and the support foot 21. At the same time, vibration will be generated during the operation of the water pump 20, and the buffer 40 can also play a buffering role, which helps to reduce the vibration and impact of the support foot 21 on the mounting bracket 10 and the fixing member 30, so as to further improve the structural stability of the water pump assembly 100.

[0051] Furthermore, the buffer 40 is sleeved on the portion of the support leg 21 located in the fixing groove 30a. In this way, the buffer 40 is sleeved on the peripheral side 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 40 and the support leg 21, so that the buffer 40 is not easy to be separated from the support leg 21, so as to ensure the buffering effect of the buffer 40 on the support leg 21.

[0052] Reference Figure 4In some structural forms, the fixing member 30 is provided with one of the snap-fitting protrusion 33 and the snap-fitting recess 14, and the mounting bracket 10 is provided with the other of the snap-fitting protrusion 33 and the snap-fitting recess 14, and the snap-fitting protrusion 33 and the snap-fitting recess 14 are correspondingly snap-fitted, so that the fixing member 30 and the mounting bracket 10 are relatively fixed. Among them, compared with other fixing forms such as threaded connection, the snap-fitting fixing form does not require the provision of additional fixing connectors, so that the connection between the fixing member 30 and the mounting bracket 10 is convenient for the staff to operate, thereby improving the assembly efficiency of the two. Specifically, the snap-fitting protrusion 33 can be a convex block, and the snap-fitting recess 14 can be a through hole or a groove. In this way, the fixing member 30 and the mounting bracket 10 are relatively close, and the convex block can be inserted into the through hole or the groove to limit the position of the convex block in other directions except the insertion direction, thereby achieving relative fixation of the fixing member 30 and the mounting bracket 10. The number of the clamping protrusion 33 and the clamping recess 14 can be set to be single, so as to simplify the structure of the fixing member 30 and the mounting bracket 10. Of course, the number of the clamping protrusion 33 and the clamping recess 14 can also be set to be multiple, and the multiple clamping protrusions 33 correspond to the multiple clamping recesses 14 one by one. In this way, by setting the form of multiple clamping protrusions 33 and multiple clamping recesses 14, the stability of the fixing member 30 and the mounting bracket 10 when they are relatively fixed can be improved.

[0053] Further, the mounting bracket 10 includes a supporting portion 11 and a connecting portion 12 connected to each other, the supporting portion 11 and the connecting portion 12 are arranged at an angle, and the connecting portion 12 is connected to a snap-on recess 14. Among them, the supporting portion 11 and the connecting portion 12 can be arranged in an "L" shape, and the supporting portion 11 and the connecting portion 12 are both connected to the inner wall of the body 200 of the indoor unit 1000 to improve the stability of the mounting bracket 10, so as to prevent the water pump 20 and the fixing member 30 from shaking relative to the body 200 during use, and further improve the reliability of the indoor unit 1000. The joint of the supporting portion 11 and the connecting portion 12 is connected in a smooth transition. In this way, the joint of the supporting portion 11 and the connecting portion 12 is more beautiful, and it is not easy to be scratched when the installer or the user touches the joint. The supporting portion 11 and the connecting portion 12 are arranged in one piece. That is, the support portion 11 and the connection portion 12 can be formed into an integral structure by stamping a plate, so that 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] Combination Figures 2 to 4Furthermore, the water pump assembly 100 also includes a water level switch 80. The main function of the water level switch 80 is to monitor and control the degree of water 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-up 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 from interfering with the water pump 20 located on the support part 11. The water level switch 80 is detachably connected to the extension portion 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 limiting portion 32 connected to each other, and the limiting portion 32 is connected to a clamping protrusion 33. The main body 31 and the limiting portion 32 can also be arranged at an angle. During installation, the limiting portion 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 to each other, and the main body 31 is provided with an avoidance opening 312, and the avoidance opening 312 is used for the pump body 22 to pass through, and then connected to the clamping recess 14 through the clamping protrusion 33, so that the main body 31 and the support portion 11 clamp and fix the plurality of supporting legs 21. In this way, the abutment positioning of the limiting portion 32 and the alignment of the avoidance opening 312 are simultaneously performed to improve the connection efficiency of the fixing member 30 and the mounting bracket 10, and improve the accuracy of the installation.

[0056] Reference Figure 6 Furthermore, the main body 31 is provided with a first connection hole 311, the support portion 11 is provided with a second connection hole 111, and 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 relatively fix the main body 31 and the support portion 11. Among them, the first connection hole 311 and the second connection hole 111 can be threaded holes, and the fastener 50 can be a screw, and the main body 31 and the support portion 11 are fixed by screws. This fixing method is relatively simple to install and easy to disassemble, which is convenient for 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 by a connection method commonly used in the field, such as a pin connection and a rivet connection.

[0057] Reference Figure 7 and Figure 8In order to improve the multifunctionality 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. The first wire fixing member 60 and the second wire fixing member 70 are both connected to the fixing member 30. The first wire fixing member 60 is used to fix the strong wire harness, and the second wire fixing member 70 is used to fix the weak wire harness. In this way, by providing the first wire fixing member 60 and the second wire fixing member 70, the strong wire harness and the weak wire harness are routed separately, which prevents the strong wire harness from generating electromagnetic interference to the weak wire harness, which is beneficial to improving the reliability of signal transmission in the weak wire harness, and makes the wiring of the strong wire harness and the weak wire harness regular. Among them, the high-voltage harness is a harness with a transmission voltage higher than 110V (for example, the power line of the water pump 20 of the indoor unit 1000), and the low-voltage harness is a harness with a transmission voltage lower than 110V (for example, the power line of the display screen of the indoor unit 1000). The first wire fixing component 60 and the second wire fixing component 70 can be an integrated structure with the fixing component 30. In this way, not only can the fixing effect of the first wire fixing component 60 and the second wire fixing component 70 on the high-voltage harness and the low-voltage harness be improved, but also the number of assembled parts in the water pump assembly 100 can be reduced, so that the overall structure of the fixing component 30 is simpler and the strength of the overall structure is higher. At the same time, the first wire fixing component 60 and the second wire fixing component 70 can be integrated on the fixing component 30 to increase the function of the water pump assembly 100.

[0058] Optionally, the first wire fixing member 60 and the second wire fixing member 70 are located on opposite sides of the fixing member 30. As a result, it is not only easy to realize the processing and manufacturing of the first wire fixing member 60 and the second wire fixing member 70, and it is not easy to cause interference, but also the spacing distance between the strong wire harness and the weak wire harness after being fixed is increased. Of course, the utility model is not limited to this, and the first wire fixing member 60 and the second wire fixing member 70 may not be arranged opposite to each other, as long as the shortest distance between the first wire fixing member 60 and the second wire fixing member 70 is greater than the safety spacing.

[0059] Optionally, the first wire fixing member 60 includes a first support plate 61 and a first claw 62, and the first support plate 61 and the first claw 62 are both connected to the fixed member 30. The first claw 62 and the first support plate 61 can be arranged at intervals along the thickness direction of the fixed member 30, and the first claw 62 is located above the first support plate 61, so that the first support plate 61 and the first claw 62 are arranged relative to each other to form a first wire fixing space 60a with a first notch 60b. Thus, the strong wire harness passes through the first notch 60b and is limited in the first wire fixing space 60a, so that the first claw 62 can limit the upper side of the strong wire harness, and the first support plate 61 can limit the lower side of the strong wire harness, so as to achieve the limitation of the strong wire harness to be placed in a centralized manner to avoid dispersion. At the same time, the strong wire harness can also be allowed to pass through the first notch 60b and pass 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 away from the fixed member 30 and the end of the first support plate 61 away from the fixed member 30 can be bent, so that the contact area of ​​the limited power harness can be increased to improve the limiting 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, so that the power harness can enter the first fixed wire space 60a more easily through the guidance of the guide surface. The first notch 60b formed by the first claw 62 and the first support plate 61 can be set away from the direction of the fixed member 30, so as to facilitate the installation and disassembly of the power harness and improve the 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 both 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 weak-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 size of the cross section of the strong wire harness is larger than the size of the cross section of the weak wire harness, the size of the second support plate 71 and the plurality of second claws 72 formed with the second notch 70b can be smaller than the size of the first notch 60b, so that the installer can clearly identify the installation position of the strong wire harness and the weak wire harness, thereby improving the installation efficiency. The second claw 72 and the second support plate 71 can be arranged at intervals 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 wire harness, and the second support plate 71 limits the lower side of the weak wire harness, thereby realizing the limiting of the weak wire harness to be placed in a centralized manner to avoid dispersion. At the same time, the weak wire harness can also be passed through the second notch 70b to pass through the second fixed wire space 70a, so as to facilitate subsequent maintenance and replacement. It should be noted that the shape of the second clamping jaw can be the same as the shape of the first clamping jaw to improve production efficiency. The second support plate 71 can be arranged in an inclined manner, and the position of the end of the second support plate 71 away from the fixing member 30 is higher than the position of the end of the second support plate 71 close to the fixing member 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 fixing member 30 under the action of gravity, so as to further improve the stability of the weak wire harness in the second fixed wire space 70a.
