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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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 .

[0076] 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.

[0077] 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.

[0078] Specifically, please combine Figure 1 , Figure 2 as well as Figure 4 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.

[0079] like Figure 3 and Figure 4 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.

[0080] The fan 50 is arranged in the air inlet chamber 11, and it can be a cross-flow fan 50, a centrifugal fan 50 or 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 53. The wind wheel 51 is arranged in a long cylindrical shape. The motor 53 is arranged at one end of the wind wheel 51 and connected to the housing 10, and the output shaft of the motor 53 is connected to the wind wheel 51. A plurality of blades are distributed along the circumference of the wind wheel 51. When the motor 53 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 diffusion chamber 12. The cross-flow fan 50 has the advantages of energy saving, large air volume, low noise and simple installation.

[0081] Combination Figure 3 and Figure 4 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.

[0082] In the embodiment of the present application, the heat exchanger 60 is arranged on the water receiving pan 32, and a water receiving groove 321 is formed at the bottom of the water receiving pan 32. During the operation of the indoor unit 100, condensed water may be formed on the heat exchanger 60, and the condensed water enters the water receiving groove 321 under the action of gravity. As time goes by, the condensed water accumulates in the water receiving groove 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 is arranged beside the water receiving pan 32 to discharge the condensed water through the water pump assembly 70.

[0083] In order to facilitate the maintenance of the water pump assembly 70, the water pump assembly 70 will be placed outside the water receiving tray 32 to facilitate maintenance operations on the water pump assembly 70. However, on the basis of realizing the external placement of the water pump assembly 70, the water pump assembly 70 usually needs to include a water pump box 71 and a water pump 73. The water pump box 71 defines a water pumping chamber 71a, and the water pumping chamber 71a is connected to the water receiving tank 321 to collect the condensed water discharged from the water receiving tank 321. In addition, the water pump 73 will be arranged in the water pumping chamber 71a to extract the condensed water through the water pump 73 and then discharge it outward. However, the water pump 73 will vibrate during operation, and the vibration is further transmitted to the side panel 40 of the first housing 20 through the water pump box 71. In this vibration transmission process, noise is easily caused.

[0084] To solve the above technical problems, please refer to Figures 5 and 6 In some embodiments, the water pump assembly 70 includes a water pump box 71, a water pump 73 and a vibration damping member 77. A water pumping chamber 71a is formed in the water pump box 71. The water pump 73 is fixed in the water pumping chamber 71a to extract water from the water pumping chamber 71a.

[0085] The water pump box 71 is roughly columnar and can be made of plastic materials such as PP (Polypropylene) and XPS (extruded polystyrene) so as to have the advantages of light weight and beautiful appearance. Of course, the water pump box 71 can also be made of other materials such as metal, which is not limited in the embodiment of the present application.

[0086] The water pump box 71 includes a first box body 711 and a second box body 712, wherein 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, for example, both are made of plastic material. Of course, the materials of the two can also be different, for example, 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. The embodiment of the present application is not limited to this.

[0087] 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.

[0088] The water pump 73 includes a pump body 731 and a connecting pin 732. The pump body 731 is the main part of the water pump 73, and is used to extract water from the water pumping cavity 71a, and then discharge the water to the outside. The connecting pin 732 is the connecting pin 732 of the water pump 73, and is used to connect with the water pump box 71, and the connecting pin 732 is connected to the outside of the pump body 731, so that the pump body 731 can be fixed in the water pumping cavity 71a by connecting the connecting pin 732 with the water pump box 71.

[0089] In some structural forms, the pump body 731 may include a shell, and the connecting foot 732 is connected to the outer side of the shell and is an integral component with the shell, so that the connection stability between the two is improved and manufacturing is facilitated. For example, the shell and the connecting foot 732 can be an integral component by injection molding. Of course, this embodiment is not limited to this, and the shell and the connecting foot 732 can also be separate components, and the two can be connected by means of snap connection, threaded connection or bonding.

[0090] 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.

[0091] Furthermore, in order to simplify the installation steps between the water pump box 71 and the water pump 73, the first box body 711 of this embodiment is provided with a first fixing portion 7112, and the second box body 712 is provided with a second fixing portion 7124, and 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 cavity 71a. In this way, when the first box body 711 and the second box body 712 are connected, the vibration damping member 77 can be fixed, thereby realizing that the pump body 731 is fixed in the water pumping cavity 71a.

[0092] In summary, the present application provides a vibration damping member 77 sleeved on the connecting leg 732, and uses the cooperation between the first fixing portion 7112 and the second fixing portion 7124 to fix the vibration damping member 77, so that the water pump assembly 70 of this embodiment has at least the following technical effects:

[0093] Firstly, 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. This can also reduce the vibration energy transmitted to the side panel 40 of the first shell 20 of the indoor unit 100. 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 to extend the service life of the connecting foot 732 and the water pump box 71. Secondly, during the actual installation process, while connecting the first box body 711 and the second box body 712, the first fixing portion 7112 and the second fixing portion 7124 can cooperate to fix the shock absorber 77 to fix the pump body 731 in the water pumping chamber 71a. In this way, there is no need to provide other fixing steps for connecting the connecting foot 732 to the water pump box 71. This ensures that the fixing effect is better and the installation convenience is improved. At the same time, this also realizes the non-threaded or less-threaded connection between the pump body 731 and the water pump box 71, so that when realizing the connection between the pump body 731 and the water pump box 71, there is no need to use or use as little as possible additional disassembly and assembly tools, and the connection convenience is greatly improved.

[0094] In actual use, it is also found that due to the low temperature of the condensed water, when the condensed water flows in the water pumping chamber 71a, moisture in the external air may condense, causing condensation.

[0095] Based on this, please refer to Figures 5 and 6In some embodiments, the water pump assembly 70 further includes a heat preservation structure 90, and the heat preservation structure 90 may be heat preservation cotton, which is low in cost and convenient to assemble. The heat preservation structure 90 wraps at least part of the outer wall surface of the water pump box 71, for example, it may wrap at least one of the outer peripheral side surface and the bottom surface of the water pump box 71, and the embodiment of the present application is not limited to this. In this way, the wrapping setting of the heat preservation structure 90 helps to reduce the heat exchange between the external air and the condensed water located in the pumping chamber 71a, thereby reducing the condensation phenomenon or avoiding the condensation phenomenon, thereby preventing the condensation phenomenon from causing water droplets to drip into the installation environment of the indoor unit 100 and causing the installation environment to become moldy.

[0096] Please refer to Figures 5 and 6 Furthermore, the second box body 712 is located below the first box body 711, and the pump body 731 has a water pumping port 7311 connected to the water pumping cavity 71a, and the water pumping port 7311 is arranged toward the second box body 712. It can be understood that the second box body 712 constructs the side wall and the bottom wall of the water pumping cavity 71a, and the first box body 711 constructs the top wall of the water pumping cavity 71a, that is, the second box body 712 will serve as the main structural part of the water pump box 71 for storing condensed water. At the same time, the arrangement of the water pumping port 7311 toward the second box body 712 will help the pump body 731 to perform water pumping operations.

[0097] Since the second box body 712 is the main structural part of the water pump box 71 for storing condensed water, condensation is easy to occur in the second box body 712. Therefore, in this embodiment, the heat preservation structure 90 wraps at least part of the outer wall surface of the second box body 712, for example, it can wrap at least one of the outer peripheral side surface and the bottom surface of the second box body 712. This embodiment of the present application does not limit this. In this way, it can effectively reduce the heat exchange, reduce the condensation phenomenon or avoid the condensation phenomenon.

[0098] Please refer to Figures 5 and 6 In some embodiments, the thermal insulation structure 90 includes a plurality of first thermal insulation members 91, wherein the plurality of first thermal insulation members 91 are separately arranged and may all be thermal insulation cotton. The plurality of first thermal insulation members 91 are sequentially spliced ​​and arranged along the circumference of the second box body 712 to cooperate with wrapping the outer peripheral side of the second box body 712. In this way, even if the outer peripheral side profile of the second box body 712 is relatively complex, a plurality of first thermal insulation members 91 with relatively simple shapes can be manufactured separately, and then the outer peripheral side of the second box body 712 can be wrapped in the form of splicing, so as to facilitate manufacturing and production while facilitating wrapping. In addition, in the splicing form of two adjacent first thermal insulation members 91, it can be ensured that the two members press against each other, thereby reducing the possibility that any one of them expands and fails to wrap the outer peripheral side of the second box body 712 well.

[0099] Please refer to Figure 6 and Figure 8 In some embodiments, the bottom surface of the second box body 712 is provided with a water storage portion 7122 protruding in a direction away from the first box body 711, and the water storage portion 7122 is formed with a water storage groove 7122a connected to the water pumping chamber 71a, and the projection of the water pumping port 7311 on the bottom wall of the water pumping chamber 71a is located in the water storage groove 7122a. The embodiment of the present application does not limit the shape of the water storage groove 7122a, which can be circular, square, etc. The bottom wall of the water storage groove 7122a is lower than the bottom wall of the water pumping chamber 71a, so that the condensed water flowing into the water pumping chamber 71a will be gathered in the water storage groove 7122a, further increasing the volume of the water pumping chamber 71a. The projection of the water pumping port 7311 on the bottom wall of the water pumping chamber 71a is located in the water storage groove 7122a, or in other words, the water pumping port 7311 is arranged opposite to the notch of the water storage groove 7122a, so as to facilitate the water pumping operation of the water pump 73.

[0100] The heat preservation structure 90 includes a second heat preservation member 92, which wraps the bottom surface of the second box body 712 and is provided with an avoidance groove 92a for the water storage part 7122 to penetrate. In this way, the second heat preservation member 92 can reduce the heat exchange between the condensed water flowing through the bottom wall of the pumping cavity 71a and the water storage tank 7122a and the external space, effectively reducing the condensation phenomenon or avoiding the condensation phenomenon.

[0101] Furthermore, the second heat-insulating member 92 may include a first heat-insulating portion and a second heat-insulating portion, wherein the first heat-insulating portion wraps the bottom surface of the second box body 712 and is provided with a through hole for the water storage portion 7122 to pass through, and the second heat-insulating portion is connected to the side of the first heat-insulating portion away from the second box body 712 to cooperate with the side wall of the through hole to enclose an avoidance groove 92a. In this way, the separate arrangement of the first heat-insulating member 91 and the second heat-insulating member 92 facilitates separate manufacturing and production.

[0102] In some embodiments, the insulation structure 90 includes the above-mentioned multiple first insulation parts 91 and the second insulation parts 92, so as to facilitate the manufacturing and production of the multiple first insulation parts 91 while facilitating the wrapping of the multiple first insulation parts 91. At the same time, the second insulation part 92 can reduce the heat exchange between the bottom wall of the pumping chamber 71a and the condensed water flowing through the water storage tank 7122a and the external space, effectively reducing condensation or avoiding the occurrence of condensation.

[0103] See also Figure 6In some embodiments, 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. The first clamping portion 7111 and the second clamping portion 7121 are adapted to be clamped, so that the first box body 711 is clamped to 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 and assembly 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.

[0104] Please continue reading Figure 6 In some structural forms, 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.

[0105] 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.

[0106] Please refer to Figure 6 to Figure 7 In some embodiments, a pressing portion 7111c is provided on the outer surface of the hook section 7111b, and the pressing portion 7111c is used to be pressed by an external force to disengage the hook section 7111b from the back of the second clamping portion 7121. Thus, by pressing the groove wall of the pressing portion 7111c, the hook section 7111b and the second clamping portion 7121 can be disengaged from the abutment, which is very convenient to operate. It can be understood that the contour of the pressing portion is in an arc shape to match the outer contour of the finger, making pressing more convenient.

[0107] Please refer to Figure 6 to Figure 7 In some embodiments, a guide slope 7111d is formed on the outer surface of the hook section 7111b, and the guide slope 7111d is used to guide and cooperate with the groove wall surface of the clamping groove 7121a, so that the hook section 7111b can contact the groove wall surface of the clamping groove 7121a more smoothly, thereby improving the smoothness of the cooperation between the first clamping portion 7111 and the second clamping portion 7121.

[0108] Please refer to Figure 6 to Figure 7In some embodiments, a pressing portion 7111c is provided on the outer surface of the hook segment 7111b, and the pressing portion 7111c is used for applying external force to make the hook segment 7111b disengage from the back side of the second clamping portion 7121, and a guide slope 7111d is formed on the outer surface of the hook segment 7111b, and the guide slope 7111d is used to guide and cooperate with the groove wall surface of the clamping groove 7121a. In this way, when the user disengages the first clamping portion 7111 from the second clamping portion 7121, the user can first press the groove wall surface of the pressing portion 7111c to achieve the disengagement of the hook segment 7111b from the second clamping portion 7121, and then under the guiding action of the guide slope 7111d, the hook segment 7111b can quickly disengage from the groove wall surface of the clamping groove 7121a, and the operation is very convenient and quick.

[0109] Optionally, the pressing portion 7111c may be a groove sunken in the outer surface of the hook segment 7111b, or may be a protrusion convexly provided on the outer surface of the hook segment 7111b, and this embodiment is not limited to this.

[0110] See also Figure 6 In some embodiments, the second box body 712 has an opening, and the second box body 712 has a flange portion 7123 extending in a direction away from the second box body 712 formed at the opening, and a plurality of limiting ribs 7125 are arranged at intervals on the inner side surface of the flange portion 7123, and each limiting rib 7125 extends along the extension direction of the flange portion 7123.

[0111] Among them, the first box body 711 is covered at the opening, and is spaced apart from the inner side surface of the flange portion 7123, and a plurality of limiting ribs 7125 abut against the first box body 711. In this way, when the first box body 711 is covered at the opening, firstly, the flange portion 7123 can block and limit the first box body 711 in a direction perpendicular to its own extension direction, so as to prevent the first box body 711 from loosening from the second box body 712. Secondly, based on the cooperation of the plurality of limiting ribs 7125, the first box body 711 can be limited in the circumferential direction of the second box body 712, so as to prevent the first box body 711 from reversing. In addition, there is a gap between the flange portion 7123 and the first box body 711. Based on the existence of the gap, if the condensed water discharged outward by the pump body 731 leaks, it can also flow back from the gap into the pumping cavity 71a, so that the pump body 731 can extract it again.

[0112] See also Figure 6In some embodiments, the water pump assembly 70 further includes a water level switch 74, which is disposed in the pumping chamber 71a to sense water level changes and send a signal to the controller of the indoor unit 100, so that the controller controls the operation of the pump body 731. For example, the water level switch 74 is disposed in the pumping chamber 71a to sensitively reflect water level changes in the pumping chamber 71a, so that the controller can control the start and stop of the pump body 731.

[0113] Optionally, the water level switch 74 includes a float 741 disposed in the pumping chamber 71a and capable of floating and changing with the water level. The water level switch 74 is used to generate a signal for the pump body 731 to operate when the water level reaches a preset water level, triggered by the float 741. Exemplarily, when the water level is low, the float 741 is at a low position, and the water level switch 74 continuously feeds back a low level to the controller, and when the water level reaches a set height, the float 741 is at a high position, and the water level switch 74 feeds back a high level to the controller, and at this time the controller controls the pump body 731 to operate.

[0114] Of course, the water level switch 74 may also adopt other optional structural forms, under the premise of being able to reflect the water level changes in the pumping chamber 71a, and the embodiment of the present application does not limit this.

[0115] Please refer to Figure 6 to Figure 7 In some embodiments, the water level switch 74 further includes a connecting column 742 , and the float 741 is sleeved on the connecting column 742 and can float along the extending direction of the connecting column 742 .

[0116] Among them, a connecting groove 7115 is formed on the first box body 711, and the bottom wall of the connecting groove 7115 is provided with an assembly groove 7116, and the connecting column 742 is slidably inserted into the assembly groove 7116, so that part of the connecting column 742 is located in the water pumping chamber 71a, and the remaining part is located in the connecting groove 7115, that is, the part located in the water pumping chamber 71a will be provided with a float 741, so that the float 741 can be located in the water pumping chamber 71a and float according to the extension direction of the connecting column 742.

[0117] It can be understood that the connection between the connecting column 742 and the assembly groove 7116 is an interference fit, and the bottom wall of the connecting groove 7115 is also provided with a deformation groove arranged at an interval with the assembly groove 7116. On the basis of the interference fit, when the connecting column 742 slides into the assembly groove 7116, the setting of the deformation groove makes the groove side of the assembly groove 7116 have a tendency to expand outward, so that the connecting column 742 can be slid into, and when the connecting column 742 slides into the preset installation position in the assembly groove 7116, the groove side of the assembly groove 7116 has a tendency to contract inward, so as to clamp the connecting column 742, realize the pre-fixation of the connecting column 742, and then the connecting column 742 and the connecting groove 7115 are fixedly connected, so that the operation is very convenient.

[0118] Furthermore, a limit stopper is provided on the side wall of the connecting groove 7115, and the limit stopper is located above the water level switch 74 to block and limit the water level switch 74 to prevent the water level switch 74 from detaching.

[0119] Please refer to Figures 6 to 8 In some embodiments, the first box body 711 is provided with a drain pipe 714, the drain pipe 714 defines a drainage channel, and the pump body 731 has a water outlet 7313. It is understandable that when the pump body 731 is running, the water drawn by the pump body 731 to the water pumping chamber 71a will be discharged to the water outlet channel through the water outlet 7313, and if the pump body 731 stops running and there is more water in the external pipeline, it is easy to cause water to flow back into the water pumping chamber 71a through the drainage channel, thereby causing water leakage in the indoor unit 100.

[0120] Based on this, the water pump assembly 70 of this embodiment further includes a water pipe 76 and a check valve 75. The water pipe 76 may be made of a rubber water pipe, which has the advantages of light weight and good heat preservation performance, and the check valve 75 may be a duckbill valve, which has good non-return performance and good flow regulation performance. This embodiment does not specifically limit the specific types of the water pipe 76 and the check valve 75.

[0121] The opposite ends of the water pipe 76 are respectively connected to the water outlet 7313 and the drainage channel, and the check valve 75 is arranged inside the water pipe 76 to allow the water outlet 7313 to be unidirectionally connected to the drainage channel. In this way, the water flowing back from the drainage channel to the water outlet 7313 can be controlled, and the backflow rate can be reduced or prevented, thereby reducing the possibility of the pumping chamber 71a being backflowed by condensed water, thereby avoiding water leakage or operation failure of the indoor unit 100 and improving safety.

[0122] Please refer to Figures 8 to 9 Furthermore, the water pipe 76 includes a first pipe section 761 and a second pipe section 762, one end of the first pipe section 761 is connected to the water outlet 7313, one end of the second pipe section 762 is connected to the end of the first pipe section 761 away from the water outlet 7313, and the other end is connected to the drainage channel.

[0123] The inner diameter of the second pipe section 762 is larger than the inner diameter of the first pipe section 761, so that a step portion 763 is formed at the joint with the first pipe section 761, and the step portion 763 can be arranged to extend along the circumferential direction of the water pipe 76. The check valve 75 is arranged in the second pipe section 762, wherein a through-port is formed in the second pipe section 762, and the check valve 75 is interference-fitted with the through-port, and the check valve 75 is limited by the step portion 763, so that the check valve 75 is stably installed in the water pipe 76.

[0124] Of course, the present application is not limited thereto. In other embodiments, the check valve 75 may be securely installed in the water pipe 76 only by interference fit with the second pipe section 762 .

[0125] Furthermore, a plurality of ribs are formed on the mouth wall of the second pipe section 762, and the plurality of ribs are arranged at intervals along the extension direction of the second pipe section 762, and each rib extends along the circumference of the second pipe section 762 to limit the abutment against the outer wall of the check valve 75, so as to further enhance the stability of the installation of the water pipe 76 on the water stop valve.

[0126] During the use of the water pump assembly 70, the water pipe 76 may be easily aged and the connection with the drain pipe 714 may become loose. Figures 8 to 9 In some embodiments, a plurality of supporting ribs 71a2 are arranged at intervals on the side walls of the pumping chamber 71a, and the plurality of supporting ribs 71a2 cooperate to abut against the outer wall surface of the step portion 763. In this way, the step portion 763 can be supported by the plurality of supporting ribs 71a2 to prevent the water pipe 76 from aging and becoming loosened from the connection with the drain pipe 714.

[0127] Please refer to Figure 6 to Figure 7 In some embodiments, a water storage tank 7113 is formed on the outer wall of the first box body 711. The drain pipe 714 is provided in the water storage tank 7113. A reflux port 7114 is provided on the outer wall of the first box body 711, and the reflux port 7114 is used to connect the water storage tank 7113 to the water pumping chamber 71a. In this way, even if the drain pipe 714 leaks, the water storage tank 7113 of this embodiment can intercept and store the leaked water, and return the water to the water pumping chamber 71a through the reflux port 7114, and the pump body 731 can extract the water again.

[0128] Furthermore, the outer surface of the water storage tank 7113 is inclined so that the water leaked from the drain pipe 714 is guided to the reflux port 7114 through the inclined setting, so that the water flows into the water pumping chamber 71a through the reflux port 7114 and is re-extracted by the pump body 731, thereby preventing the water from accumulating in the water storage tank 7113.

[0129] Please refer to Figure 8 and Fig.10 In some embodiments, the first fixing portion 7112 cooperates with the second fixing portion 7124 to form a fixing groove 71c with one side open, wherein at least a portion of the vibration damping member 77 extends into the fixing groove 71c, and the groove wall surface of the fixing groove 71c is used to abut and fix the vibration damping member 77.

[0130] It can be understood that the fixing groove 71c includes a groove top wall and a groove bottom wall that are arranged opposite to each other, and a groove side wall connected between the groove top wall and the groove bottom wall, wherein the groove top wall and the groove bottom wall can abut against two opposite surfaces of the fixed vibration damping member 77 along the thickness direction thereof, and the groove side wall can abut against the side surface of the fixed vibration damping member 77. In this way, the abutting and fixing area of ​​the first fixing portion 7112, the second fixing portion 7124 and the vibration damping member 77 can be increased, so as to enhance the fixing effect of the vibration damping member 77 and reduce the possibility of the vibration damping member 77 being disconnected from the first fixing portion 7112 and the second fixing portion 7124.

[0131] Of course, the present application is not limited thereto. In other embodiments, the first fixing portion 7112 and the second fixing portion 7124 can respectively abut against two opposite surfaces of the fixed vibration damper 77 along the thickness direction thereof, thereby cooperating to fix the vibration damper 77 .

[0132] See also Fig.10 Further, a first half groove 7112a is formed on the surface of the first fixing portion 7112 facing the second fixing portion 7124, and a second half groove 7124a is formed on the surface of the second fixing portion 7124 facing the first fixing portion 7112. When the first box body 711 and the second box body 712 are connected, the first half groove 7112a is connected to the second half groove 7124a to form a fixing groove 71c.

[0133] It can be understood that the first half groove 7112a and the second half groove 7124a each occupy half the volume of the fixed groove 71c. On the basis of the form of fixing the shock absorber 77 together through the two half grooves, it is possible to avoid the abutment force generated by either the first fixing part 7112 or the second fixing part 7124, thereby preventing either of them from being damaged by excessive rebound force of the shock absorber 77, thereby achieving uniform distribution of the rebound force on the first fixing part 7112 and the second fixing part 7124, and also facilitating the docking of the first fixing part 7112 and the second fixing part 7124, thereby improving installation convenience.

[0134] Of course, in other embodiments, the first fixing portion 7112 may be used to form the top wall of the fixing groove 71c, and the second fixing portion 7124 may be used to form the side walls and bottom wall of the fixing groove 71c, and the embodiment of the present application is not limited to this.

[0135] Please refer to Figure 6 , Fig.10 and Fig.11In some embodiments, the connecting legs 732 and the vibration damping member 77 each include multiple and are arranged one by one, the multiple connecting legs 732 are arranged at intervals along the circumference of the pump body 731, the first fixing portion 7112 and the second fixing portion 7124 each include multiple, wherein one first fixing portion 7112 cooperates with one second fixing portion 7124 to form a fixing groove 71c to fix one vibration damping member 77. In this way, the stability of the pump body 731 fixed in the water pumping chamber 71a can be further improved by setting the multiple first fixing portions 7112 and the second fixing portions 7124.

[0136] Exemplarily, the number of connecting feet 732, vibration damping members 77, first fixing portions 7112 and second fixing portions 7124 are all three. The three connecting feet 732 are arranged at intervals along the circumference of the pump body 731 and are arranged one by one corresponding to the three vibration damping members 77. At the same time, a first fixing portion 7112 and a second fixing portion 7124 cooperate to fix a vibration damping member 77.

[0137] See also Figure 6 Further, the second box body 712 is also provided with a connection portion 78 for fixing the water pump box 71 to the indoor unit 100, and one of the plurality of second half grooves 7124a is provided adjacent to the connection portion 78. For example, the indoor unit 100 further includes a motor bracket, the motor bracket is used to install the motor 53 of the fan 50, and the motor bracket is fixedly connected to the connection portion 78 to fix the water pump box 71 to the indoor unit 100.

[0138] On this basis, in order to improve the connection strength between the connecting part 78 and the motor bracket, it is necessary to improve the strength of the part of the water pump box 71 where the connecting part 78 is provided. Based on this, the side wall of the water pumping chamber 71a is provided with a supporting rib 71a1, and the supporting rib 71a1 is located below the second half groove 7124a where the adjacent connecting part 78 is provided, and extends downward to support the part of the shock absorbing member 77 located outside the second half groove 7124a.

[0139] In this way, on the one hand, the support rib 71a1 can be provided to enhance the structural strength of the portion of the water pump box 71 where the connecting portion 78 is provided, thereby facilitating enhancing the stability of the connection between the connecting portion 78 and the motor bracket; on the other hand, the support rib 71a1 can also assist the second half groove 7124a to support the shock absorber 77, thereby enhancing the fixing effect of the shock absorber 77 and preventing the shock absorber 77 from falling off from the fixing groove 71c.

[0140] Further, it can be understood that the water pumping chamber 71a may include a first cavity and a second cavity, wherein the first cavity is used to accommodate the pump body 731, and the second cavity is used to accommodate the water pipe 76. The volume of the water pipe 76 is usually smaller than the volume of the pump body 731, so the volume of the corresponding second cavity will also be designed to be smaller than the volume of the first cavity. The second half groove 7124a disposed adjacent to the connecting portion 78 described above is located at the connection between the first cavity and the second cavity, or is located in the second cavity.

[0141] Firstly, because the water pump 73 is connected and fixed by a plurality of connecting feet 732 of the same structure, and the position of the pump body of the water pump 73 is fixed in the first cavity, the positions of the plurality of second half grooves 7124a are also relatively fixed. If the bottom area of ​​the second half groove 7124a arranged near the connecting portion 78 is enlarged by filling material in the pumping cavity 71a, demolding cannot be performed well due to the limited space in the second cavity. It may even be necessary to add a slanted top structure in the mold to eject the structure formed by the part of the filling material. This will make the mold structure complicated and increase the cost of the mold. In this embodiment, a support rib 71a1 is provided below the second half groove 7124a provided adjacent to the connecting portion 78, and the support rib 71a1 includes a plurality of sub-support ribs provided at intervals. The support of the plurality of sub-support ribs can fix the vibration damping member 77, and the gaps between the plurality of sub-support ribs can facilitate demolding of the mold. In this way, the mold is not restricted by the space of the second cavity, and there is no need to design structures such as inclined tops in the mold. This makes the mold design simple, saves materials, and helps reduce costs.

[0142] See also Figure 7 In some embodiments, the first fixing portion 7112 is provided with an observation port 7112b. The shape of the observation port 7112b may be circular, square, etc., which is not limited in the embodiment of the present application.

[0143] The observation port 7112b penetrates the first fixing portion 7112 to communicate with the first half groove 7112a. Thus, the connection between the vibration damper 77 and the connecting leg 732 can be observed through the observation port 7112b, such as whether the two are properly connected or not, and whether the connecting leg 732 is sleeved with the vibration damper 77 to prevent the vibration damper 77 from being missed during the water pump assembly 70.

[0144] Optionally, the second fixing portion 7124 is provided with an observation port 7112b, wherein the shape of the observation port 7112b may be circular, square, etc., which is not limited in the embodiment of the present application.

[0145] The observation port 7112b penetrates the second connecting leg 7124 to communicate with the second half groove 7124a. Thus, the connection between the vibration damper 77 and the connecting leg 732 can be observed through the observation port 7112b, such as whether the two are properly connected, and whether the two are not properly connected. Another example is to observe whether the connecting leg 732 is sleeved with the vibration damper 77 to prevent the vibration damper 77 from being missed during the water pump assembly 70.

[0146] Optionally, the first fixing portion 7112 is provided with an observation port 7112b, and the second fixing portion 7124 is provided with an observation port 7112b. Thus, by providing a plurality of observation ports 7112b, the connection between the vibration damping member 77 and the connecting foot 732 can be observed from different angles, which is more convenient.

[0147] Please refer to Figure 10 to Figure 11 In some embodiments, the vibration damper 77 includes a vibration damper body 771 and a plurality of first abutting ribs 772. The vibration damper body 771 is the main part of the vibration damper 77, and is used to sleeve the connecting foot 732, that is, the vibration damper body 771 is formed with a sleeve groove 771a, the connecting foot 732 is arranged in the sleeve groove 771a, and the vibration damper body 771 plays a major vibration damping effect. The plurality of first abutting ribs 772 are all roughly U-shaped, and the plurality of first abutting ribs 772 are connected to the outer surface of the vibration damper body 771 at intervals, and are used to abut against the groove wall surface of the first half groove 7112a and the groove wall surface of the second half groove 7124a. In this way, the contact form between the first abutting rib 772 and the groove wall surface of the first half groove 7112a and the groove wall surface of the second half groove 7124a can be transformed from surface contact to line contact, so that the deformation degree of the vibration damper 77 is improved to achieve a better vibration damping effect.

[0148] See also Fig.11 Furthermore, the vibration damping member 77 further includes a plurality of second abutting ribs 773, and the plurality of first abutting ribs 772 are all roughly U-shaped. The plurality of second abutting ribs 773 are connected to the groove wall surface of the sleeve groove 771a at intervals to abut against the connecting leg 732. In this way, the contact form between the second abutting ribs 773 and the connecting leg 732 can be transformed from surface contact to line contact, so that the deformation degree of the vibration damping member 77 is improved to achieve a better vibration reduction effect.

[0149] See also Fig.11In some embodiments, the vibration damper 77 is provided with a first alignment hole 771b, and the connecting leg 732 is provided with a second alignment hole 7321 for being arranged opposite to the first alignment hole 771b. It is understandable that when the vibration damper 77 is sleeved to the preset installation position of the connecting leg 732, the first alignment hole 771b will be arranged opposite to the second alignment hole 7321. In this way, whether the vibration damper 77 is arranged to the preset installation position of the connecting leg 732 can be judged by whether the first alignment hole 771b is opposite to the second alignment hole 7321.

[0150] See also Fig.12 In some embodiments, the indoor unit 100 further includes a water outlet pipe 103, one end of which is connected to the drain pipe 714, and the other end can be used to connect to a water collecting device or the outside world to discharge the condensed water. It is worth noting that the water outlet pipe 103 is extended from one end connected to the drain pipe 714 to the other end away from the drain pipe 714 from top to bottom. For example, in order to facilitate the structural arrangement and reduce the material stress, the water outlet pipe 103 can extend in an arc shape and pass through the housing 10 to be connected to the external pipeline. As a result, the part of the water outlet pipe 103 close to the drain pipe 714 is lower than the drain pipe 714. It can be understood that when the condensed water in the water receiving tray 32 is completely discharged or the water level of the condensed water in the water receiving tray 32 is reduced to a certain height, the water pump assembly 70 will stop working. Due to the height difference between the drain pipe 714 and the main part of the water outlet pipe 103, the condensed water in the water outlet pipe 103 can be effectively reduced or avoided to flow back, reducing the risk of leakage.
