Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a cleaning device and a clothing processing equipment. Background Art

[0002] Heat pump dryers, for example, are laundry processing equipment. Heat exchange components are installed within the dryer's circulation duct. These components convert the damp, cold airflow from the laundry processing chamber into a dry, hot airflow. The dry, hot airflow then flows back into the chamber, exchanging heat with the wet laundry inside to form a damp, cold airflow. The damp, cold airflow then flows out of the chamber, repeating this cycle to dry the laundry. Because the airflow carries lint, the heat exchange components are prone to lint accumulation after prolonged use. Failure to promptly remove the lint from the components can severely impact heat exchange performance and create odors. Summary of the Invention

[0003] In view of this, embodiments of the present application hope to provide a cleaning device and a clothes processing device, wherein the cleaning device can be used to clean the heat exchange component.

[0004] To achieve the above objectives, the present invention provides a cleaning device comprising:

[0006] A water retaining member movably accommodated in the accommodating cavity can switch between blocking the first flow opening and the second flow opening under the action of the water flow from the water inlet and the water flow from the flow opening.

[0008] In some embodiments, a portion of the bottom surface of the accommodating cavity close to the first flow opening is lower than a portion of the bottom surface of the accommodating cavity far from the first flow opening.

[0009] In some embodiments, the cleaning device includes a guide plate located in the accommodating cavity, and the guide plate extends from the water inlet to the second flow outlet to guide the water flow from the water inlet to the second flow outlet.

[0010] In some embodiments, the cleaning device includes a limiting plate disposed on a side of the flow-through port away from the first flow-through port. The limiting plate and the surrounding portion of the first flow-through port jointly define a movement channel, and the water blocking member is capable of moving along the movement channel.

[0011] In some embodiments, the water blocking member is spherical.

[0012] In some embodiments, the cleaning device includes a push rod slidably passing through the flow-through port and capable of pushing the water blocking member to move.

[0013] In some embodiments, the cleaning device includes a water storage box communicated with the flow-through port;

[0014] In a state where water enters from the water inlet, the water blocking member blocks the first flow-through port, and the water flow at the water inlet flows into the second flow-through port; in a state where the water inlet stops water inlet, the water blocking member blocks the second flow-through port under the impact of the water flow in the water storage box, and the water flow in the water storage box flows into the first flow-through port.

[0015] In some embodiments, the water storage box is formed with an overflow port. When the water level in the water storage box is higher than a preset height, the water flow in the water storage box is discharged through the overflow port.

[0016] In some embodiments, an overflow plate with the preset height is arranged in the water storage box. There is a spaced space between the overflow plate and the top plate of the water storage box. The overflow plate divides the space in the water storage box into a water storage cavity and an overflow cavity. The flow-through port is communicated with the water storage cavity, and the overflow port is formed at the bottom of the water storage box and communicated with the overflow cavity.

[0017] In some embodiments, the cleaning device includes a water inlet waterway and a reversing valve. Both the water inlet and the flow-through port are communicated with the water inlet waterway, and the reversing valve is arranged in the water inlet waterway to selectively conduct the water inlet or the flow-through port.

[0035] It should be noted that, without conflict, the embodiments in the present application and the technical features in the embodiments can be combined with each other. The detailed description in the specific implementation manners should be understood as an explanatory description of the purpose of the present application and should not be regarded as an improper limitation of the present application.

[0036] The orientation or positional relationship described in the description of the embodiments of the present application is the orientation or positional relationship when the clothing treatment device is in normal use. For example, Figure 1 、 Figure 2 and Figure 6 The orientation or positional relationship shown. It should be understood that these orientation terms are only for convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0037] Please refer to Figure 1 and Figure 2 , the embodiments of the present application provide a cleaning device. The cleaning device includes a sprinkler 100 and a water blocking member 200. The sprinkler 100 is formed with a water inlet 100a, a receiving cavity 100b, a flow port 100c, a first water spray channel 100d and a second water spray channel 100e. The first water spray channel 100d has a first flow port 100d' and a first water spray port 100d". The second water spray channel 100e has a second flow port 100e' and a second water spray port 100e". The water inlet 100a, the flow port 100c, the first flow port 100d' and the second flow port 100e' are all communicated with the receiving cavity 100b.

[0038] The water blocking member 200 is movably disposed in the accommodation cavity 100b. Under the action of the water flow at the water inlet 100a and the water flow at the communication port 100c, the water blocking member 200 can switch between blocking the first flow port 100d' and the second flow port 100e'. That is to say, the water flow at the water inlet 100a and the water flow at the communication port 100c impact the water blocking member 200 to move. One of the first flow port 100d' and the second flow port 100e' is blocked by the water blocking member 200, and the other of the first flow port 100d' and the second flow port 100e' is opened. The water flow can enter the opened one of the first flow port 100d' and the second flow port 100e'. In this way, the first water spray port 100d'' and the second water spray port 100e'' spray water alternatively. For example, if the water blocking member 200 blocks the first flow port 100d', the second flow port 100e' is in an open state, and the water flow can spray out from the second water spray port 100e'' (please refer to Figure 1 ). Another example, if the water blocking member 200 blocks the second flow port 100e', the first flow port 100d' is in an open state, and the water flow can spray out from the first water spray port 100d'' (please refer to Figure 2 ).

[0039] For the cleaning device provided by the embodiment of the present application, on the one hand, the first water spray port 100d'' and the second water spray port 100e'' spray water alternatively. The water output of the first water spray port 100d'' or the second water spray port 100e'' is relatively larger, the water flow velocity is relatively faster, the flushing strength is greater, and the flushing effect is better. On the other hand, the water flow at the water inlet 100a and the water flow at the communication port 100c drive the water blocking member 200 to move. The water blocking member 200 alternatively blocks the first flow port 100d' and the second flow port 100e' to realize the alternative water spraying of the first water spray port 100d'' and the second water spray port 100e''. The structure is simple, and it is not necessary to use valve components such as solenoid valves to control the on-off of the first water spray channel 100d and the second water spray channel 100e, reducing the number of valve components, being safe and reliable, saving energy, and having low cost.

[0040] Taking the cleaning device for a laundry treatment device as an example, the type of the laundry treatment device is not limited. For example, the laundry treatment device can be a dryer or a washing and drying integrated machine, etc. Please refer to Figure 1 and Figure 2 , the laundry treatment device provided by the embodiment of the present application includes a cylinder assembly, a drying circulation air duct 1, a heat exchange component, and the cleaning device according to any one of the embodiments of the present application. The cylinder assembly has a laundry treatment cavity. The drying circulation air duct 1 is communicated with the laundry treatment cavity. The heat exchange component is located in the drying circulation air duct 1. Both the first water spray port 100d'' and the second water spray port 100e'' are used to clean the heat exchange component. The laundry treatment cavity is used to place the laundry to be treated, such as wet laundry to be dried.

[0041] Since wet clothes to be dried are usually prone to produce fluff, paper scraps and / or hair and other debris, the debris carried in the wet and cold airflow is easy to adhere to the heat exchange component. In the clothing processing device provided by the embodiment of the present application, the heat exchange component is used to convert the wet and cold airflow from the clothing processing chamber into a dry and hot airflow, and the dry and hot airflow then flows back into the clothing processing chamber. The first water spray port 100d" and the second water spray port 100e" can be aimed at different parts of the heat exchange component, and the first water spray port 100d" and the second water spray port 100e" selectively spray water to respectively flush different parts of the heat exchange component, thereby achieving zoned flushing of the heat exchange component. In this way, the heat exchange component is flushed in zones through the first water spray port 100d" and the second water spray port 100e", and the debris adhering to the heat exchange component is washed off to ensure the heat exchange effect of the heat exchange component.

[0042] For example, in some embodiments, the drum assembly includes an outer drum and an inner drum rotatably disposed within the outer drum, the inner drum defining a laundry processing chamber. For example, the inner drum's rotational axis may be horizontal, and the inner drum may have a loading port on its front side that communicates with the laundry processing chamber, through which a user may place laundry into the laundry processing chamber. Thus, as the inner drum rotates, it drives the laundry within the laundry processing chamber, causing the laundry to continuously change position during movement, allowing for full contact with the dry, hot air flow and improving drying efficiency.

[0043] In some embodiments, the drum assembly includes only a single barrel, which has a laundry processing chamber. For example, the barrel's rotation axis can be horizontal, and the front of the barrel has a loading port connected to the laundry processing chamber, through which the user can load laundry into the laundry processing chamber. In this way, as the single barrel rotates, it drives the laundry in the laundry processing chamber, and the laundry constantly changes its position during movement, allowing it to fully contact the dry and hot air flow, thereby improving drying efficiency.

[0044] It should be noted that, in the embodiment of the present application, the front side refers to the side facing the user, and the rear side, which is opposite to the front side, refers to the side facing away from the user.

[0045] In some implementations, see Figures 1 to 3, the drying cycle air duct 1 includes a heat exchange shell 11 located at the bottom side of the cylinder assembly. The heat exchange assembly includes an evaporator and a condenser. Both the evaporator and the condenser are located inside the heat exchange shell 11. Along the flow direction of the air flow, the evaporator is located upstream of the condenser. An opening is formed on the cover plate 111 of the heat exchange shell 11. The spray head 100 is located on the top side of the heat exchange shell 11. Both the first water spray opening 100d” and the second water spray opening 100e” are aligned with the opening of the cover plate 111. The heat exchange shell 11 includes a bottom frame and a cover plate 111. The bottom frame forms a heat exchange groove with an opening on the top side. The evaporator and the condenser are located inside the heat exchange groove. The cover plate 111 is used to cover the opening on the top side of the heat exchange groove. For example, the evaporator and the condenser can be fin-tube heat exchangers. The refrigerant flows inside the evaporator and the condenser to exchange heat with the air flow inside the drying cycle air duct 1. That is to say, on the air flow path, the air flow first flows through the evaporator and then through the condenser. For example, the evaporator is located in front of the condenser. The wet and cold air flow from the laundry treatment chamber enters the heat exchange shell 11 from the front side, first flows through the evaporator and then through the condenser. The wet and cold air flow from the laundry treatment chamber exchanges heat with the evaporator to dehumidify and form a dry and cold air flow. The dry and cold air flow is heated by the condenser to form a dry and hot air flow. The dry and hot air flow returns to the laundry treatment chamber, and the dry and hot air flow exchanges heat with the wet clothes in the laundry treatment chamber again to form a wet and cold air flow. The first water spray opening 100d” and the second water spray opening 100e” spray water downward alternatively. The water flow sprays the evaporator and / or the condenser through the opening of the cover plate 111.

[0046] It should be noted that the top side refers to the direction towards the ceiling, and the bottom side refers to the direction towards the ground.

[0047] In some embodiments, please refer to Figure 2 , the opening of the cover plate 111 is aligned with the front side surface of the evaporator. Since the wet and cold air flow from the laundry treatment chamber first contacts the front side surface of the evaporator, in this way, almost all the lint carried by the air flow adheres to the front side surface of the evaporator. By aligning the first water spray opening 100d” and the second water spray opening 100e” with the opening of the cover plate 111 to wash the front side surface of the evaporator for centralized cleaning, in this way, the opening of the heat exchange shell 11 can be smaller, and the airtightness inside the heat exchange shell 11 is better.

[0048] In some embodiments, the laundry treatment device includes a condensate pan and a water pump. The condensate pan is located at the bottom side of the heat exchange assembly and is used to receive the condensate from the heat exchange assembly. The water pump pumps the condensate in the condensate pan into the water inlet 100a. That is to say, the condensate is used as the water source for flushing the heat exchange assembly, realizing the secondary utilization of the condensate, saving energy and protecting the environment.

[0049] In some embodiments, the laundry treatment device includes a controller. The controller controls the start and stop of the water pump to automatically flush the heat exchanger, with a high degree of automation.

[0050] Exemplarily, in some embodiments, please refer to Figure 2and Figure 6 In this case, the width of the first water spray channel 100d gradually increases along the longitudinal direction of the nozzle 100, and the width of the second water spray channel 100e gradually increases along the longitudinal direction of the nozzle 100. For example, the projection profile of the nozzle 100 in the top-bottom direction is generally trumpet-shaped. The water inlet 100a, the accommodation cavity 100b, and the circulation port 100c are formed at the small-head end of the nozzle 100, and the first water spray port 100d” and the second water spray port 100e” are formed at the large-head end of the nozzle 100. In this way, both the first water spray port 100d” and the second water spray port 100e” are substantially flat and elongated, and both the first water spray port 100d” and the second water spray port 100e” can cover the part of the heat exchange assembly in the transverse direction of the nozzle 100, so that the heat exchange assembly can be efficiently and powerfully flushed.

[0051] In some embodiments, please refer to Figure 2 and Figure 4 In this case, the water inlet 100a is located on one side wall in the longitudinal direction of the nozzle 100, both the first water spray port 100d” and the second water spray port 100e” are located on the other side wall in the longitudinal direction of the nozzle 100, both the first flow-through port 100d’ and the second flow-through port 100e’ are formed inside the nozzle 100 and are arranged at intervals in the transverse direction of the nozzle 100, and the circulation port 100c is formed on the side wall of the nozzle 100 in the transverse direction close to the first flow-through port 100d’. Specifically, both the first flow-through port 100d’ and the second flow-through port 100e’ are arranged opposite to the water inlet 100a.

[0052] Here, the water flow at the water inlet 100a enters the accommodation cavity 100b along the longitudinal direction of the nozzle 100, the water flow at the circulation port 100c enters the accommodation cavity 100b along the transverse direction of the nozzle 100, and the water flow direction of the water inlet 100a and the water flow direction of the circulation port 100c are perpendicular. For example, the water blocking member 200 can move along the transverse direction of the nozzle 100 under the impact of the water flow at the circulation port 100c. In this way, through the action of the water flow at the water inlet 100a and the water flow at the circulation port 100c, the water blocking member 200 can switch between blocking the first flow-through port 100d’ and the second flow-through port 100e’.

[0053] It should be noted that in the embodiments of the present application, the top-bottom direction, the longitudinal direction, and the transverse direction of the nozzle 100 are perpendicular to each other and jointly form a three-dimensional perpendicular coordinate system. The longitudinal direction is consistent with the front-back direction of the clothing treatment device.

[0054] In some embodiments, please refer to Figure 4, the part of the bottom surface of the accommodation cavity 100b near the first water passing port 100d' is lower than the part of the bottom surface of the accommodation cavity 100b far from the first water passing port 100d'. In the initial state where both the water inlet 100a and the flow port 100c are not passing water, the water blocking member 200 can be located at the position where the first water passing port 100d' is located under the action of gravity to block the first water passing port 100d'. In this way, when water enters the accommodation cavity 100a from the water inlet 100a, since the first water passing port 100d' is blocked, the water flow from the water inlet 100a can enter the second water passing port 100e'. When water enters the accommodation cavity 100a from the flow port 100c, the water flow at the flow port 100c will impact the water blocking member 200 to open the first water passing port 100d', and the water blocking member 200 moves to the position where the second water passing port 100e' is located to block the second water passing port 100e'. In this way, the water flow from the flow port 100c can enter the first water passing port 100d'. With such a design, the water inlet 100a and the flow port 100c respectively introduce water to impact the water blocking member 200 so that it can switch between blocking the first water passing port 100d' and the second water passing port 100e'.

[0055] In some embodiments, please refer to Figure 4 , the cleaning device includes a guide plate 300 located in the accommodation cavity 100b. The guide plate 300 extends from the water inlet 100a towards the second water passing port 100e' to direct the water flow from the water inlet 100a towards the second water passing port 100e'. In this way, the water flow from the water inlet 100a can flow more concentratedly towards the second water passing port 100e'.

[0056] In some embodiments, please refer to Figure 4 , the cleaning device includes a restricting plate 400. The restricting plate 400 is arranged on the side of the flow port 100c far from the first water passing port 100d'. The restricting plate 400 and the surrounding part of the first water passing port 100d' jointly define a movement channel 400a, and the water blocking member 200 can move along the movement channel 400a. That is to say, the restricting plate 400 is located on the side of the flow hole along the longitudinal direction of the nozzle 100 far from the first water passing port 100d'. In this way, on the one hand, the movement channel 400a can restrict the movement direction of the water blocking member 200, and the water blocking member 200 switches between the first water passing port 100d' and the second water passing port 100e' along the movement channel 400a, to a certain extent avoiding the disorderly movement of the water blocking member 200 in the accommodation cavity 100b. On the other hand, the movement channel 400a can also play a role in guiding the water flow so that the water flow flows more concentratedly in the same direction.

[0057] In some embodiments, please refer to Figure 4 , the restricting plate 400 is connected to the surrounding part of the flow port 100c and the guide plate 300. In this way, the water flowing through the gap between the restricting plate 400 and the guide plate 300 is avoided.

[0058] In some embodiments, refer to Figure 4 , the water blocking member 200 is spherical. The maximum cross-section of the water blocking member 200 is larger than the first water passing port 100d' and the second water passing port 100e', so that the first water passing port 100d' and the second water passing port 100e' can be blocked. On the one hand, under the action of the water flow at the water inlet 100a and the water flow at the circulation port 100c, the water blocking member 200 can roll in the accommodation cavity 100b, and the frictional resistance received by the water blocking member 200 is small, so that the water blocking member 200 can quickly switch between the first water passing port 100d' and the second water passing port 100e'. On the other hand, when neither the water inlet 100a nor the water blocking member 200 is passing water, the water blocking member 200 can maintain the initial state of blocking the first water inlet 100a under the action of gravity.

[0059] In some embodiments, refer to Figure 4 , the cleaning device includes a push rod 500, and the push rod 500 is slidably disposed in the circulation port 100c and can push the water blocking member 200 to move. The push rod 500 can perform a linear reciprocating motion under the action of the water flow. On the one hand, the water flow at the circulation port 100c can push the push rod 500 close to the water blocking member 200. Under the action of the impact force of the water flow at the circulation port 100c, the water flow at the circulation port 100c and the push rod 500 jointly push the water blocking member 200 to move. In this way, it can more effectively ensure the quick switching of the water blocking member 200. On the other hand, the size of the circulation port 100c can be larger than the size of the water blocking member 200. Due to the blocking of the push rod 500, the water blocking member 200 can be prevented from blocking the circulation port 100c. In this way, the amount of water at the circulation port 100c can be larger, so as to more powerfully impact the water blocking member 200.

[0060] In some embodiments, refer to Figures 1 to 3 , the cleaning device includes a water storage box 600 communicated with the circulation port 100c. In the state where water enters from the water inlet 100a, the water blocking member 200 blocks the first water passing port 100d', and the water flow at the water inlet 100a flows into the second water passing port 100e'. In the state where the water inlet 100a stops supplying water, the water blocking member 200 blocks the second water passing port 100e' under the impact of the water flow in the water storage box 600, and the water flow in the water storage box 600 flows into the first water passing port 100d'. In this way, the water storage box 600 can store water liquid. When it is necessary to supply water to the accommodation cavity 100b through the circulation port 100c, the water liquid stored in the water storage box 600 is used to supply water to the accommodation cavity 100b through the circulation port 100c.

[0061] The water flow of the water storage box 600 can come from the water inlet 100a. Specifically, when the water inlet 100a is in the state of admitting water, the water blocking member 200 blocks the first water passing port 100d'. Part of the water flow at the water inlet 100a flows into the second water passing port 100e', and another part of the water flow at the water inlet 100a flows into the water storage box 600 through the communication port 100c. When the water inlet 100a stops admitting water briefly, the water blocking member 200 blocks the second water passing port 100e' under the impact of the water flow in the water storage box 600, and the water flow in the water storage box 600 flows into the first water passing port 100d'. That is to say, the water inlet 100a is periodically turned on or off to repeatedly supply water or cut off water to the accommodation cavity 100b.

[0062] Here, the water storage box 600 temporarily stores a part of the water flow from the water inlet 100a. For example, the water pump pumps the condensed water to the water inlet 100a. Part of the condensed water flows into the second water passing port 100e', and the corresponding part of the heat exchange component is flushed through the second water spraying port 100e". Another part of the condensed water flows into the water storage box 600 through the communication port 100c for temporary retention. When the water pump stops working and the water inlet 100a stops admitting water, the condensed water in the water storage box 600 flows back to the communication port 100c under the action of gravity, pushing the water blocking member 200 to move to the second water passing port 100e' and blocking the second water passing port 100e'. The condensed water in the water storage box 600 flows into the first water passing port 100d', and the other part of the corresponding heat exchange component is flushed through the first water spraying port 100d". With such a design, water can be supplied only through the water inlet 100a, without the need to additionally add a water pump and valve components to supply water to the communication port 100c. The water pump and / or valve components can be reduced, and the start or stop of the water pump can be controlled by a controller to realize water spraying from the first water spraying port 100d" or the second water spraying port 100e". The structure is simple and the operation is convenient.

[0063] In some embodiments, please refer to Figure 3 , the water storage box 600 is formed with an overflow port 600a. When the water level in the water storage box 600 is higher than the preset height, the water flow in the water storage box 600 is discharged through the overflow port 600a. In this way, the water level in the water storage box 600 is maintained at the preset height through the overflow port 600a, so as to temporarily store a preset amount of water liquid in the water storage box 600.

[0064] In some embodiments, please refer to Figure 3, an overflow plate 610 with a preset height is configured inside the water storage box 600. There is a spaced space 610a between the overflow plate 610 and the top plate of the water storage box 600. The overflow plate 610 divides the space inside the water storage box 600 into a water storage chamber 600b and an overflow chamber 600c. The circulation port 100c is communicated with the water storage chamber 600b. The overflow port 600a is formed at the bottom of the water storage box 600 and is communicated with the overflow chamber 600c. With such a design, the water flow at the circulation port 100c flows into the water storage chamber 600b. When the water level in the water storage chamber 600b is higher than the overflow plate 610, it enters the overflow space through the spaced space 610a and is quickly discharged through the overflow port 600a. The overflow port 600a is located at the bottom of the water storage box 600 so as to quickly and fully drain the water flow in the overflow chamber 600c.

[0065] In some embodiments, the overflow port 600a can be communicated with the drainage pipeline of the laundry treatment device. In this way, the water flow flowing out of the overflow port 600a can be discharged from the laundry treatment device through the drainage pipeline.

[0066] In other embodiments, the overflow port 600a can also be communicated with the condensate pan. For example, if the water storage box 600 is arranged on the cover plate 111 of the heat exchange housing 11, an opening can be made on the cover plate 111 of the heat exchange housing 11, and a pipe fitting passes through the opening of the cover plate 111 to communicate the overflow port 600a and the condensate pan. In this way, the water flow flowing out of the overflow port 600a can flow back into the condensate pan again.

[0067] In some embodiments, the water storage box 600 can be fixed on the replacement cover plate 111 by means of snap connection, screw connection, etc. In other embodiments, the water storage box 600 can also be integrally formed with the cover plate 111.

[0068] In some embodiments, the difference between this embodiment and the foregoing embodiments is that in the foregoing embodiments, the water in the water storage box 600 is used to provide power for the water blocking member 200, while in this embodiment, the flow direction of the water flow in the water inlet waterway is changed by the reversing valve 800 so that the water flow in the water inlet waterway can flow to the circulation port 100c, thereby pushing the water blocking member 200, and then moving the water blocking member 200 to the second water passing port 100e'. The water blocking member 200 blocks the water flow from passing through the second water passing port 100e' and allows the water flow to enter the first water passing port 100d' and flow out from the first water spraying port 100d", so as to wash the heat exchange assembly below.

[0069] Specifically, please refer to Figure 5 and Figure 6, the cleaning device includes a water inlet waterway 700 and a reversing valve 800. The water inlet 100a and the circulation port 100c are both communicated with the water inlet waterway 700. The reversing valve 800 is arranged in the water inlet waterway 700 to selectively conduct the water inlet 100a or the circulation port 100c. That is to say, when the reversing valve 800 conducts the water inlet waterway 700 and the water inlet 100a, the circulation port 100c is cut off. In this way, the water flow in the water inlet waterway 700 only enters the water inlet 100a. When the reversing valve 800 diverts the water inlet waterway 700 and the circulation port 100c, the water inlet 100a is cut off. In this way, the water flow in the water inlet waterway 700 only enters the circulation port 100c. With such a design, only one water inlet circuit can be set, and the reversing valve 800 is used to control the water inlet of one of the water inlet 100a and the circulation port 100c, so as to provide water flow impacts in different directions for the water blocking member 200, so that the water blocking member 200 can switch between blocking the first flow port 100d' and the second flow port 100e', with a simple structure and convenient operation.

[0070] In some embodiments, the water inlet waterway 700 can be communicated with the condensate pan, the water pump is arranged on the water inlet waterway 700, and the drain pipe can be connected to the reversing valve 800. In this way, when it is necessary to directly discharge the condensate in the condensate pan, the reversing valve 800 can be controlled to cut off the water inlet 100a and the circulation port 100c, conduct the water inlet waterway 700 and the drain pipe, and the water pump drives the condensate in the condensate pan to enter the drain pipe through the water inlet waterway 700 and be discharged.

[0071] Exemplarily, in some embodiments, please refer to Figure 5 and Figure 6 , the water inlet waterway 700 includes a main waterway 710, a first branch 720 and a second branch 730. The main waterway 710 is communicated with the first port of the reversing valve 800. The first branch 720 is communicated with the second port of the reversing valve 800 and the water inlet 100a. The second branch 730 is communicated with the third port of the reversing valve 800 and the circulation port 100c. The on-off of the first port, the second port and the third port of the reversing valve is controlled to control the on-off between the main waterway 710, the first branch 720 and the second branch 730.

[0072] In some embodiments, when the total water path 710 is in communication with the first port of the reversing valve 800 and the first branch 720 is in communication with the second port of the reversing valve 800, the water flow passing through the second port of the reversing valve 800 enters the water inlet 100a. Since the communication port 100c is not in communication, the water blocking member 200 in the accommodating cavity 100b always blocks the first flow port 100d'. In this case, the water flow enters the second flow port 100e' and is ejected from the second water spraying port 100e" to wash the heat exchange component below; when the total water path 710 is in communication with the first port of the reversing valve 800 and the second branch 730 is in communication with the third port of the reversing valve 800, the water flow passing through the third port of the reversing valve 800 enters the communication port 100c and then enters the accommodating cavity 100b. At this time, the water blocking member 200 at the low position is pushed to the second flow port 100e' under the impact of the water flow to block the second flow port 100e'. Since the water blocking member 200 blocks the second flow port 100e', the water flow enters the nozzle 100 from the first flow port 100d' and is ejected from the first water spraying port 100d" to clean the heat exchange component below.

For those skilled in the art, this application can have various changes and modifications.
