[0056] In the present application, an up-down direction ZZ, a front-back direction YY, and a left-right direction XX are defined, and the up-down direction ZZ, the front-back direction YY, and the left-right direction XX are arranged at an angle to each other.

[0057] The embodiment of the present application provides a HVAC system, which includes an indoor unit 100 and an outdoor unit (not shown in the figure), and the indoor unit 100 is connected to the outdoor unit through cables, pipes, etc., so as to work together to adjust the indoor environment. It can be understood that the indoor unit 100 is set indoors and is usually installed in the form of a suspended ceiling to adjust the indoor temperature.

[0058] Please refer to Figures 1 to 3 The indoor unit 100 includes a housing 10 , a fan 50 , a heat exchanger 60 and a water pump assembly 70 .

[0059] The housing 10 defines a heat exchange air duct suitable for the indoor unit 100 for gas flow. The heat exchange air duct includes an air inlet chamber 11, a pressure diffusion chamber 12, and a heat exchange chamber 13 which are connected in sequence. The housing 10 also forms an air suction port 14 connected to the air inlet chamber 11 and an air outlet 15 connected to the heat exchange chamber 13, so that the gas can enter the heat exchange air duct from the air suction port 14, and can pass through the air inlet chamber 11, the pressure diffusion chamber 12, and the heat exchange chamber 13 in sequence, and finally flow out from the air outlet 15.

[0060] To facilitate the assembly of the indoor unit 100, the housing 10 includes a first housing 20 and a second housing 30. The first housing 20 and the second housing 30 can be made of metal materials such as aluminum alloy or stainless steel to meet the requirements of high strength and corrosion resistance, or the first housing 20 and the second housing 30 can also be made of plastic materials to achieve lightweight housing 10. They can be connected individually or in combination by means of clamping, riveting, welding and bolting, etc., and the present application does not limit this.

[0061] Specifically, please combine Figures 1 to 3 The first housing 20 includes an upper cover 20a and two side panels 40. The two side panels 40 are spaced apart in the left-right direction XX. The upper cover 20a is generally disposed above the two side panels 40 and extends along the front-rear direction YY. The upper cover 20a is connected to the two side panels 40 on both sides along the left-right direction XX. In this way, the upper cover 20a and the two side panels 40 are spliced ​​to form the first housing 20. The second housing 30 is spaced apart from the upper cover 20a in the up-down direction ZZ. The second housing 30 is connected to the two side panels 40 on both sides along the left-right direction XX. The first housing 20, the second housing 30 and the two side panels 40 are spliced ​​to form the housing 10.

[0062] like Figure 2 and Figure 3 As shown, along the front-to-back direction YY from back to front, the upper cover 20a includes an air inlet chamber rear shell 24, an air inlet chamber upper shell 21, a pressure diffuser chamber upper shell 22 and a heat exchange chamber upper shell 23 connected in sequence, and the second shell 30 includes an air inlet chamber front shell, a shell body and a water receiving tray 32 connected in sequence. The air inlet chamber rear shell 24 and the air inlet chamber front shell are spaced apart in the front-to-back direction YY, and the air inlet chamber rear shell 24, the air inlet chamber upper shell 21, the air inlet chamber front shell and the side panels 40 define the air inlet chamber 11. The pressure diffuser chamber upper shell 22 and the pressure diffuser chamber lower shell 31 are spaced apart in the upper line direction ZZ, and the pressure diffuser chamber upper shell 22, the pressure diffuser chamber lower shell 31 and the side panels 40 define the pressure diffuser chamber 12, and the heat exchange chamber upper shell 23, the water receiving tray 32 and the side panels 40 define the heat exchange chamber 13.

[0063] The fan 50 is disposed in the air inlet chamber 11, and can be a cross-flow fan 50, a centrifugal fan 50, an axial flow fan 50, etc. Taking the cross-flow fan 50 as an example, the fan 50 includes a wind wheel 51 and a motor assembly 53, and the wind wheel 51 is arranged in a long cylindrical shape and is arranged in the air inlet chamber 11 of the heat exchange air duct.

[0064] The motor assembly 53 includes a motor bracket 531 and a drive motor 533. The drive motor 533 is arranged at one end of the wind wheel 51 and mounted on the motor bracket 531. The drive motor 533 is connected to the wind wheel 51 in a transmission manner, that is, the output shaft of the drive motor 533 is connected to the wind wheel 51. The wind wheel 51 has a plurality of blades distributed along its circumference. When the drive motor 533 drives the wind wheel 51 to rotate, the rotating blades can cause the gas to flow from the air inlet chamber 11 to the pressure diffuser chamber 12. The crossflow fan 50 has the advantages of energy saving, large air volume, low noise, and simple installation.

[0065] Combination Figure 2 and Figure 3 The heat exchanger 60 is accommodated in the heat exchange cavity 13, and is used to exchange heat with the airflow flowing through the heat exchange cavity 13 and passing through the heat exchanger 60. For example, a plurality of refrigerant pipes are provided in the heat exchanger 60, and the gas exchanges heat with the refrigerant in the pipe when passing through the heat exchanger 60, thereby changing the temperature of the gas. During cooling, the gas exchanges heat with the refrigerant in the heat exchanger 60 to form low-temperature air; during heating, the gas exchanges heat with the refrigerant in the heat exchanger 60 to form heated air. The shape of the heat exchanger 60 of the present application can be a variety of shapes such as straight line, V-shaped, arc-shaped or wavy, which are not limited here.

[0066] In the embodiment of the present application, the heat exchanger 60 is arranged on the water receiving pan 32, and a water receiving tank 321 is arranged in the water receiving pan 32. During the operation of the indoor unit 100, condensed water may be formed in the heat exchanger 60, and the condensed water enters the water receiving tank 321 under the action of gravity. As time goes by, the condensed water accumulates in the water receiving tank 321 and the water level gradually rises. In order to facilitate the discharge of the condensed water, the indoor unit 100 is further provided with a water pump assembly 70, which can be arranged beside the water receiving pan 32 to discharge the condensed water through the water pump assembly 70.

[0067] In order to improve the stability of the water pump assembly 70 installed in the housing 10, please refer to Figures 4 to 6 In some embodiments, the water pump assembly 70 includes a water pump 73 and a water pump box 71. The water pump 73 is connected to the water receiving tank 321 to extract water from the water receiving tank 321. In this way, the water pump 73 can extract water from the water receiving tank 321 in a timely manner and then discharge the water to the outside to avoid condensed water from accumulating in the water receiving tank 321.

[0068] The water pump box 71, as the fixed body of the water pump assembly 70, can be roughly columnar and can be made of plastic materials such as PP (Polypropylene) and XPS (extruded polystyrene) so that the water pump box 71 has the advantages of light weight and beautiful appearance. Among them, the water pump 73 is installed in the water pump box 71. Among them, the water pump box 71 defines a water pumping chamber 71a, the water pumping chamber 71a is connected to the water receiving tank 321, and the water pump 73 is accommodated in the water pumping chamber 71a to extract water flowing from the water receiving tank 321 to the water pumping chamber 71a. In this way, by accommodating the water pump 73 in the water pumping chamber 71a, the water pump box 71 can play a certain protective role on the water pump 73.

[0069] The water pump box 71 is provided with a first connection portion 78 and a second connection portion 79. It is understandable that the first connection portion 78 and the second connection portion 79 can be provided on adjacent sides of the water pump box 71. The first connection portion 78 is fixedly connected to the motor bracket 531, wherein the connection between the two can be a detachable connection form such as a snap connection or a threaded connection, or a non-detachable connection form such as welding or bonding, which is not limited in this embodiment.

[0070] The second connection portion 79 is fixedly connected to the housing 10 , wherein the connection between the two may be a detachable connection such as a snap connection or a threaded connection, or may be a non-detachable connection such as welding or bonding, which is not limited in this embodiment.

[0071] To sum up, the water pump box 71 of the embodiment of the present application is provided with a first connecting portion 78 and a second connecting portion 79, and is fixedly connected to the motor bracket 531 and the housing 10 respectively through the first connecting portion 78 and the second connecting portion 79, so that when the staff inspects the water pump 73, there is no need to disassemble the water receiving tray 32, but can directly operate the water pump 73, thereby reducing steps, simplifying operations, reducing maintenance difficulty, and improving work efficiency. At the same time, the ceiling does not need to be provided with an inspection port corresponding to the position of the water receiving tray 32, thereby simplifying the construction of the ceiling.

[0072] Moreover, the arrangement of the first connection portion 78 and the second connection portion 79 can also ensure that there are at least two connections between the water pump box 71 and other components of the indoor unit 100, so that the water pump box 71 is more stable on the housing 10, thereby facilitating the improvement of the stability of the water pump 73 installed on the water pump box 71.

[0073] Please refer to Figures 4 to 6In some embodiments, the first connection portion 78 is detachably fixedly connected to the motor bracket 531, for example, the two can be detachably connected in a form of snap connection, screw connection, etc., which is convenient for disassembly and firmly connected. The second connection portion 79 is detachably fixedly connected to the housing 10, for example, the two can be detachably connected in a form of snap connection, screw connection, etc., which is convenient for disassembly and firmly connected.

[0074] In this way, the present embodiment is arranged in a detachable form, which helps to improve the convenience of maintenance by the staff. When the water pump 73 needs to be repaired, the first connection part 78 can be disconnected from the motor bracket 531, and then the second connection part 79 can be disconnected from the shell 10, so that the water pump assembly 70 can be disassembled for subsequent maintenance or replacement of the water pump 73.

[0075] Moreover, in some indoor unit 100 models that do not have a water pump 73 when leaving the factory, if the user needs to install a water pump assembly 70 later, the water pump assembly 70 can be quickly installed on the indoor unit 100 through the detachable cooperation of the first connecting part 78 and the motor bracket 531, and the detachable cooperation of the second connecting part 79 and the shell 10, which is very convenient to operate.

[0076] See also Figure 6 , Figure 8 as well as Fig.10 Further, the water pump box 71 includes a first box body 711 and a second box body 712. The first box body 711 and the second box body 712 together define the outline of the entire water pump box 71, and in terms of the materials used by the first box body 711 and the second box body 712, the materials of the two can be the same, such as both are made of plastic materials. Of course, the materials of the two can also be different, such as one of the two is made of plastic material and the other is made of metal material, so as to reduce the overall weight of the water pump box 71 while ensuring that the water pump box 71 has a certain strength, and the embodiment of the present application is not limited to this.

[0077] The first box body 711 and the second box body 712 can be arranged along the vertical direction ZZ, and the two are connected and cooperate to define the pumping chamber 71a. It can be understood that the first box body 711 and the second box body 712 arranged separately are more conducive to production and disassembly, and are convenient for repairing the water pump 73, which can improve work efficiency.

[0078] Among them, the first box body 711 and the second box body 712 cooperate with each other to form the first connecting part 78 and the second connecting part 79. In this way, after the first box body 711 and the second box body 712 are connected and assembled, the first connecting part 78 and the second connecting part 79 are formed, and the two separate components of the first box body 711 and the second box body 712 can be used to ensure the structural strength of the first connecting part 78 and the second connecting part 79, thereby ensuring the connection strength between the first connecting part 78 and the motor bracket 531, and the connection strength between the second connecting part 79 and the shell 10.

[0079] Please refer to Figure 5 to Figure 6 Further, the motor bracket 531 may be a cover structure, specifically, the motor bracket 531 includes a first cover 5311 and a second cover 5313, and the first cover 5311 and the second cover 5313 are covered to enclose a fixed cavity for accommodating the driving motor 533. At least one of the first cover 5311 and the second cover 5313 is connected to the housing 10.

[0080] The first cover 5311 and the second cover 5313 cooperate to clamp and fix the first connection part 78. It can be understood that the clamping and fixing of the first connection part 78 by two covers is more conducive to improving the clamping stability of the motor bracket 531 on the first connection part 78, making the connection of the water pump box 71 more stable.

[0081] In order to further improve the efficiency of the connection between the first connecting portion 78 and the motor bracket 531, please refer to Figure 5 to Figure 6 In some embodiments, the first connection portion 78 includes a first sub-connection portion 781 and a second sub-connection portion 782 .

[0082] The first sub-connecting portion 781 is disposed on the first box body 711, and the second sub-connecting portion 782 is disposed on the second box body 712, and cooperates with the first sub-connecting portion 781 to form a positioning opening 7813, wherein a positioning column 5311b is provided on the surface of the first cover body 5311 facing the second cover body 5313, and the positioning column 5311b is passed through the positioning opening 7813.

[0083] A positioning column 5311b is provided on the surface of the first cover body 5311 facing the second cover body 5313, and the positioning column 5311b is passed through the positioning port 7813. In this way, in actual operation, the first cover body 5311 and the first connecting portion 78 can be positioned by the positioning cooperation between the positioning column 5311b and the positioning port 7813, and then the second cover body 5313 is covered on the first cover body 5311 to clamp and fix the connecting plate 781. In this way, it will be more convenient during the assembly process, and the connection position will be more accurate, thereby improving the clamping effect of the first cover body 5311 and the second cover body 5313 on the first connecting portion 78.

[0084] Please refer to Figures 6 to 8 In some embodiments, the first connecting portion 78 includes a first connecting plate 7811 and a first surrounding frame 7812 connected to the outer side of the first connecting plate.

[0085] The second sub-connection part 782 includes a second connection plate 7821 and a second enclosure 7822 connected to the outer side of the second connection plate 7821. The second connection plate 7821 is arranged in affixed with the first connection plate 7811 and together forms a positioning opening 7813. The second enclosure 7822 is arranged in affixed with the first enclosure 7811. In this way, the present embodiment can improve the structural strength of the first sub-connection part 7811 by setting the first enclosure 7812 and connecting the first enclosure 7812 to the outer side of the first connection plate 7811, thereby improving the stability of the connection between the first connection part 78 and the motor bracket 531. Similarly, the present embodiment can improve the structural strength of the second sub-connection part 782 by setting the second enclosure 7822 and connecting the second enclosure 7822 to the outer side of the second connection plate 7821, thereby improving the stability of the connection between the first connection part 78 and the motor bracket 531.

[0086] Please refer to Figures 6 to 8 Furthermore, the first enclosure 7812 cooperates with the first connecting plate 7811 to form a positioning groove 7814, and the surface of the first cover 5311 facing the second cover 5313 is also provided with a positioning boss 5311c, and the positioning column 5311b is penetrated through the positioning boss 5311c. Among them, the positioning boss 5311c is used to be embedded in the positioning groove 7814. In this way, in the actual operation process, the positioning boss 5311c and the positioning groove 7814 can be positioned and matched first, and then the positioning column 5311b and the positioning port 7813 can be positioned and matched, so that the first cover 5311 and the second cover 5313 can clamp and fix the first connecting portion 78. In this way, it will be more convenient in the assembly process, and the connection position will be more accurate, which improves the clamping effect of the first cover 5311 and the second cover 5313 on the first connecting portion 78.

[0087] Please refer to Figures 6 to 8 In some embodiments, the first cover 5311 is fixedly connected to the housing 10, and the second cover 5313 is detachably connected to the first cover 5311 to clamp or release the first connection portion 78. In this way, by setting the connection between the first cover 5311 and the second cover 5313 as a detachable connection, in the actual disassembly process, when the first connection portion 78 and the motor bracket 531 need to be disassembled, it is only necessary to separate the first cover 5311 from the second cover 5313, that is, to disassemble and remove the first cover 5311, and then the first connection portion 78 can be disassembled from the motor bracket 531, and then the water pump assembly 70 can be taken out, which is very convenient to operate.

[0088] Please refer to Figure 5 to Figure 6 Further, the first cover body 5311 is provided with a connection groove 5311a, and the indoor unit 100 further includes a locking structure 90, and the locking structure 90 includes a sliding body 91 and a locking body 92. The sliding body 91 is slidably connected to the second cover body 5313. It can be understood that a slide groove can be formed on the second cover body 5313, and the sliding body 91 is slidably arranged in the slide groove, and an operating part is provided on the side of the sliding body 91 away from the locking body 92. In this way, during the actual operation, the staff can operate the operating part to make the sliding body 91 slide in the slide groove.

[0089] The locking body 92 may be cylindrical, and the shape of the connecting groove 5311a may be adapted to be circular, so that the two can cooperate more smoothly. The locking body 92 is connected to the sliding body 91, and driven by the sliding body 91, it can be inserted into or separated from the connecting groove 5311a along the sliding direction of the sliding body 91, so that the second cover 5313 can be connected or disconnected from the first cover 5311.

[0090] Of course, the present application is not limited thereto, and in other embodiments, the first cover body 5311 and the second cover body 5313 may also be in other detachable forms such as screw connection or snap connection.

[0091] Please refer to Figures 4 to 5 Further, the housing 10 includes a casing 16 and the above-mentioned water collecting pan 32, and the motor bracket 531 is connected to the casing 16. It can be understood that the casing 16 can include the above-mentioned first casing 20, the front shell of the air inlet chamber and the casing body, wherein the water collecting pan 32 is connected to the casing 16, and the casing 16 and the water collecting pan 32 cooperate to define at least a portion of the heat exchange air duct.

[0092] The housing 16 has a side wall 161 along the left-right direction XX of the indoor unit 100, that is, the side wall 161 is the wall of the side panel 40 of the first housing 20. A through hole is provided on the side wall 161, and the second connection part 79 includes a first pin 7911 and a second pin 7912, the first pin 7911 is provided on the first box body 711, and the second pin 7912 is provided on the second box body 712. Among them, the first pin 7911 and the second pin 7912 are passed through the through hole to be plugged into the side wall 161 of the housing 16. It can be understood that the first pin 7911 and the second pin 7912 can be semi-cylindrical in shape, and the two can be combined into a cylindrical shape, so that the second connection part 79 is cylindrical.

[0093] In this way, this embodiment facilitates the connection operation between the second connecting part 79 and the housing 16 by plugging the connecting bracket into the side wall 161 of the housing 16. In actual operation, the second connecting part 79 can be aligned with the through hole first, and then the first pin 7911 and the second pin 7912 can be inserted into the through hole. Then, the operation of plugging the second connecting part 79 into the housing 16 can be completed, which is stable and fast.

[0094] It can be understood that, with the first cover body 5311 and the second cover body 5313 of the motor bracket 531 clamping the first connecting part 78, the motor bracket 531 can basically fix the water pump box 71. Furthermore, the second connecting part 79 is inserted into the side wall 161 of the casing 16. In this way, the water pump box 71 is fixed at two positions, which can effectively improve the fixing effect of the water pump box 71. In addition, the second connecting part 79, based on being passed through the through hole, can further prevent the water pump box 71 from flipping over, which is beneficial to improving the stability of the installation of the water pump box 71. During the actual disassembly and assembly process, taking the disassembly of the water pump assembly 70 as an example, the second cover body 5313 can be disassembled and removed. At this time, the second cover body 5313 and the first cover body 5311 release the clamping of the first connecting part 78. Then, the second connecting part 79 is pulled out of the through hole to realize the disassembly of the water pump assembly 70. At the same time, during disassembly, there is no need to rely on external disassembly tools, for example, there is no need to use disassembly tools such as screwdrivers for disassembly on the basis of non-threaded connections, and the operation is very convenient.

[0095] In order to facilitate the insertion of the first pin 7911 and the second pin 7912 into the via hole, please refer to Figure 5 , Figure 6 as well as Figure 8 In some structural forms, a deformation gap 7913 is formed between the first pin 7911 and the second pin 7912, so that at least one of the first pin 7911 and the second pin 7912 can be elastically deformed when the side wall of the through hole squeezes the outer wall surface of the insertion end, so that the second connection part 79 can be easily inserted into the through hole, which is convenient for operation. In addition, based on the existence of the deformation gap 7913, even if there is an error in the manufacturing of the second connection part 79, and the error causes the outer diameter of the second connection part 79 to be larger than the inner diameter of the through hole, the deformation gap 7913 can be used to allow the second connection part 79 to be inserted into the through hole, thereby reducing the difficulty of manufacturing.

[0096] In order to improve the smoothness of the second connecting portion 79 when passing through the via hole, please refer to Figure 5 , Figure 6 as well as Figure 8 In some structural forms, at least a portion of the outer circumference of the first pin 7911 and at least a portion of the outer circumference of the second pin 7912 are formed with a guide surface 7914.

[0097] The guide surface 7914 is used to guide and cooperate with the side wall of the via hole when the first pin 7911 and the second pin 7912 pass through the via hole. In this way, the second connection part 79 is smoother when passing through the via hole through the guide surface 7914 and the side wall of the via hole, which is convenient for operation.

[0098] Please refer to the figure Figure 5 , Figure 6 as well as Figure 8 In some embodiments, the vias include multiple holes, and the multiple vias are spaced apart on the side wall 161. The second connecting portion 79 includes multiple holes, and the multiple second connecting portions 79 correspond to the multiple vias one by one. In this embodiment, the provision of multiple second connecting portions 79 is conducive to improving the stability of the connection between the second connecting portion 79 and the housing 16. For example, the second connecting portion 79 may include two holes, and the number of vias is two, and one second connecting portion 79 corresponds to one via. Of course, in other embodiments, the number of the second connecting portion 79 and the via can be one, and this embodiment does not limit this.

[0099] Please refer to Figures 4 to 5 Further, the housing 10 includes a casing 16 and the above-mentioned water receiving tray 32. It can be understood that the casing 16 can include the above-mentioned first casing 20, the front shell of the air inlet chamber and the casing body, wherein the water receiving tray 32 is connected to the casing 15, and the casing 16 cooperates with the water receiving tray 32 to define at least a portion of the heat exchange air duct.

[0100] The indoor unit 100 further includes a connecting pipe 80, which can be made of materials such as plastic or resin for easy processing. This embodiment does not specifically limit the form of the connecting pipe 80, and its shape can be cylindrical.

[0101] One end of the connecting pipe 80 is connected to the water receiving pan 32, and the other end is connected to the water pump box 71, so as to connect the water receiving tank 321 and the water pumping chamber. In this way, the water receiving tank 321 and the water pumping chamber are formed into a communicating vessel structure through the connecting pipe 80, and the condensed water in the water receiving tank 321 can flow into the water pumping chamber through the connecting pipe 80, and then be discharged from the water pumping chamber under the suction action of the water pump 73, so as to realize the operation of discharging the condensed water in the water receiving tank 321. On the basis that the two ends of the connecting pipe 80 are respectively connected to the water receiving pan 32 and the water pump box 71, the water pump box 71 can be connected to the water receiving pan 32 through the connecting pipe 80, so as to further improve the stability of the water pump assembly 70 disposed in the housing 10.

[0102] Moreover, the setting of the connecting pipe 80 is also highly flexible, thereby making the setting of the water pump assembly 70 more flexible and convenient for structural arrangement; on the other hand, the setting of the connecting pipe 80 can avoid the high processing precision and operating difficulty required for the direct connection between the water pump box 71 and the water receiving tray 32, thereby reducing production costs, improving production efficiency, and making the disassembly and assembly of the water pump assembly 70 more convenient, further improving work efficiency.

[0103] See also Fig.10 In some embodiments, the water pump assembly further includes a vibration damper 77. The water pump 73 includes a pump body 731 and a connecting leg 732. The pump body 731 is used to extract water from the water pumping cavity 71a. The connecting leg 732 is connected to the outer side of the pump body 731. The vibration damper 77 is sleeved on the connecting leg 732.

[0104] The vibration damping member 77 can be a rubber member so that it has excellent elasticity and vibration absorption performance. Of course, the vibration damping member 77 can also be other plastic members with vibration reduction function, which is not limited in the embodiment of the present application. It can be understood that during the actual operation of the pump body 731 of the water pump 73, the pump body 731 generates a certain degree of vibration, which will cause the connecting foot 732 to collide with the water pump box 71. Based on this, the vibration damping member 77 is sleeved on the connecting foot 732, which helps to reduce the vibration and impact of the connecting foot 732 on the water pump box 71 and reduce the generation of noise. At the same time, it can avoid the hard contact between the connecting foot 732 and the water pump box 71 to extend the service life of the connecting foot 732 and the water pump box 71.

[0105] The first box body 711 is provided with a first fixing portion 7112 , and the second box body 712 is provided with a second fixing portion 7124 . The first fixing portion 7112 can cooperate with the second fixing portion 7124 to fix the vibration damping member 77 , so as to fix the pump body 731 in the water pumping chamber 71 a .

[0106] In this way, based on the setting of the vibration damping member 77, the vibration energy transmitted from the connecting foot 732 to the water pump box 71 can be absorbed to reduce the generation of noise, and thus the vibration energy transmitted to the side panel 40 of the first housing 20 of the indoor unit 100 can also be reduced. At the same time, the vibration damping member 77 can also avoid the hard contact between the connecting foot 732 and the water pump box 71, so as to extend the service life of the connecting foot 732 and the water pump box 71. Secondly, in the actual installation process, while connecting the first box body 711 and the second box body 712, the first fixing part 7112 and the second fixing part 7124 can cooperate to fix the vibration damping member 77, so as to fix the pump body 731 in the water pumping chamber 71a. In this way, there is no need to set up other fixing steps for connecting the connecting foot 732 and the water pump box 71, so that the installation convenience is improved while ensuring a better fixing effect.

[0107] See also Figure 8 and Fig.10 In some structural forms, one of the first box body 711 and the second box body 712 is provided with a first clamping portion 7111 , and the other is provided with a second clamping portion 7121 .

[0108] The first clamping portion 7111 and the second clamping portion 7121 are adapted to be clamped together, so that the first box body 711 is clamped with the second box body 712. In this way, the assembly steps of the first box body 711 and the second box body 712 can be simplified, and no additional disassembly tools are required for disassembly, which improves the convenience of disassembly between the first box body 711 and the second box body 712, and at the same time can ensure the connection stability between the two.

[0109] It can be understood that during the installation of the water pump 73 by the water pump box 71, since there is no threaded connection between the water pump 73 and the water pump box 71, the water pump assembly 70 can be assembled without the need for additional disassembly tools throughout the process. Then, during the assembly of the water pump assembly 70 in the body, the first connecting portion 78 and the second connecting portion 79 respectively have no threaded connection with the motor bracket 531 and the housing 10. Therefore, there is no need for additional disassembly tools throughout the process, and the operation is very convenient and quick.

[0110] See also Figure 8 and Fig.10 Further, the first clamping portion 7111 includes a root segment 7111a and a hook segment 7111b, one end of the root segment 7111a is connected to the first box body 711 or the second box body 712, and the other end is connected to the hook segment 7111b.

[0111] The second clamping portion 7121 is provided with a clamping groove 7121a, the root section 7111a is inserted into the clamping groove 7121a, and the hook section 7111b abuts against the back of the second clamping portion 7121. In this way, the root section 7111a is inserted into the clamping groove 7121a, which is very convenient to operate, and the hook section 7111b abuts against the back of the second clamping portion 7121, which can ensure the connection stability between the first clamping portion 7111 and the second clamping portion 7121.
