[0011] One object of the present application is to provide a spray system for a clothing processing device that can reduce the occurrence of clogging of a nozzle assembly.

[0012] The embodiment of the present application provides a spray system for a clothes treating device, which includes a nozzle assembly, an air pump, a control valve and a liquid storage container.

[0013] The nozzle assembly has an air inlet and a liquid inlet. The air inlet of the nozzle assembly is connected to the air outlet of the air pump through an air pipe, and the liquid inlet of the nozzle assembly is connected to the control valve outlet of the control valve through a liquid flow channel.

[0014] When the control valve is in the working state, the liquid flow path is open; when the control valve is in the non-working state, the liquid flow path is closed, or the liquid can only flow from the control valve outlet of the control valve along the liquid flow path to the nozzle assembly in one direction.

[0015] The air pump is used to input positive pressure airflow into the air inlet of the nozzle assembly. The liquid in the liquid flow channel is sucked into the liquid inlet of the nozzle assembly under the action of the positive pressure airflow. The airflow and liquid are mixed in the nozzle assembly to form a liquid spray, which is used to be sprayed into the clothing processing barrel of the clothing processing equipment.

[0016] In the above embodiment, liquid is drawn into the nozzle assembly by airflow, where it mixes with the liquid to form a liquid spray. When the control valve (i.e., the spray system) is not operating, the water passage is sealed or flows in one direction, preventing foreign matter from entering the nozzle assembly or control valve from within the clothing treatment device. This reduces the risk of nozzle assembly or control valve blockage and ensures long-term stable and reliable operation of the spray system.

[0017] In at least one embodiment, the control valve includes a piston valve for opening or closing a communication channel between a control valve inlet and a control valve outlet of the control valve. When the control valve is in a working state, the piston valve opens the communication channel, thereby allowing the liquid flow channel to be connected; when the control valve is in a non-working state, the piston valve closes the communication channel, thereby closing the liquid flow channel.

[0018] In the above embodiment, by integrating the piston valve into the control valve, the spray system can have fewer components, high integration, and convenient spatial layout. The piston valve has a simple structure, small size, reliable performance, and is easy to integrate into the control valve.

[0019] In at least one embodiment, the control valve further includes a one-way valve mechanism installed to a control valve inlet or a control valve outlet of the control valve.

[0020] In the above embodiment, the one-way valve mechanism can make the liquid flow only in one direction from the control valve outlet of the control valve along the liquid flow channel to the nozzle assembly, thereby preventing foreign matter from entering the nozzle assembly or the control valve from inside the clothing processing device, reducing the occurrence of blockage of the nozzle assembly or the control valve, and ensuring that the spray system operates stably and reliably for a long time.

[0021] In at least one embodiment, the control valve is a multi-channel switching valve, which includes multiple liquid inlets and one air inlet. In the working state of the multi-channel switching valve, the multi-channel switching valve can switch its different liquid inlets or connect the air inlet to its control valve outlet.

[0022] In the above embodiment, the multi-channel switching valve enables liquid from different liquid inlets to be supplied to the nozzle assembly, which is then sprayed into the laundry tub, enriching the functionality of the laundry treatment device. Furthermore, the multi-channel switching valve also allows gas from the air inlet to be supplied to the nozzle assembly, allowing for gas flushing of the pipeline. The use of a multi-channel switching valve reduces the number of components, achieves high integration, and facilitates space layout.

[0023] In at least one embodiment, the spray system for the clothing processing device also includes an installation box, which includes multiple connectors. Multiple liquid storage containers can be freely installed on the installation box and are respectively connected to the multiple connectors. The multiple liquid inlets of the multi-channel switching valve are respectively connected to the multiple connectors.

[0024] In the above embodiment, the spray system can switch between using liquids in different liquid storage containers and spraying them into the laundry treatment tub through the nozzle assembly. Multiple liquid storage containers can be freely installed in the installation box, allowing for replacement or refilling of liquids by replacing the liquid storage containers. This facilitates operation and allows for the use of a wider variety of laundry treatment liquids within a limited space, providing a richer functionality. The multiple liquid storage containers are connected to the multiple connectors of the installation box, and the multiple liquid inlets of the multi-channel switching valve are connected to the multiple connectors of the installation box. When replacing the liquid storage containers, the connection between the multiple liquid inlets of the multi-channel switching valve and the multiple connectors of the installation box remains unaffected, resulting in convenient operation, stable connections, and a low risk of leakage.

[0025] In at least one embodiment, the nozzle assembly includes a detachably mounted nozzle housing, a spray head, and a nozzle cover.

[0026] The nozzle shell has a shell air channel and a shell water channel,

[0027] The nozzle has a nozzle air channel and a nozzle water channel. The downstream end of the nozzle water channel is bent and connected to the nozzle air channel, thereby forming a Venturi tube structure at the downstream end of the nozzle. The nozzle air channel is connected to the shell air channel, and the nozzle water channel is connected to the shell water channel.

[0028] The nozzle cover is detachably connected to the nozzle housing, and the spray head is positioned between the nozzle cover and the nozzle housing.

[0029] In the above embodiment, the venturi tube structure is formed in the nozzle assembly, which can work stably for a long time and is not prone to leakage. The nozzle assembly is a detachable structure, which is easy to process, clean and maintain.

[0030] In at least one embodiment, the nozzle assembly further includes a fluid connection joint and a nozzle filter. The fluid connection joint is detachably snap-connected to the nozzle housing, and the nozzle filter is disposed between the fluid connection joint and the nozzle housing.

[0031] In the above embodiment, a filter is provided in the liquid passage of the nozzle assembly, which can effectively reduce the entry of foreign matter during the use of the nozzle assembly, prevent the nozzle from being blocked, and increase the service life of the nozzle.

[0032] In at least one embodiment, the spray system for a laundry treatment device further comprises:

[0033] a tray, the air pump and the control valve are mounted to the tray,

[0034] An air pump filter and a filter cover, wherein the air pump filter is sealed and fixed in the filter cover, the filter cover is installed on the tray, and the air inlet of the air pump is connected to the filter cover through an air suction pipe, so that the air filtered by the air pump filter enters the air pump through the air inlet of the air pump.

[0035] In the above embodiment, an air pump filter is installed at the air inlet of the air pump, and a filter cover is installed above the air pump filter. This not only filters the air but also effectively prevents the accumulation of foreign matter and impurities on the filter, thereby improving the cleanliness of clothes processed by the clothing processing device. The air pump, control valve, and air pump filter are installed on a tray, which can achieve modular assembly and convenient installation.

[0036] In at least one embodiment, the tray is installed horizontally, and the tray includes a downwardly arranged ventilation hole, and the air pump filter covers the ventilation hole. When the air pump is working, the air flow passes through the ventilation hole of the tray and the air pump filter into the air inlet of the air pump.

[0037] In the above embodiment, the installation method of the tray is simple, the layout is reasonable, and the gas flow path is simple and reasonable.

[0038] In at least one embodiment, the liquid storage container includes a liquid filling port, and a container filter is disposed in the liquid filling port.

[0039] In the above embodiment, foreign matter can be prevented from entering the liquid storage container, so that the spray system is not easily blocked, thereby increasing the reliability and service life of the spray system.

[0057] The following describes exemplary embodiments of the present application with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible embodiments of the present application, nor to limit the scope of the present application.

[0058] See also Figures 1A to 2A , an embodiment of the present application provides a clothes treating device. The clothes treating device may include a clothes treating device spray system 10. As an example, the clothes treating device may be a clothes dryer, a washing machine, etc.

[0059] First refer to Figures 2A to 6 The spray system 10 for a laundry treatment apparatus according to an embodiment of the present application (hereinafter sometimes referred to as the spray system 10 ) is introduced. The spray system 10 may include a nozzle assembly 100 , an air pump 200 , a control valve 300 , and liquid storage containers 410 , 420 .

[0060] See especially Figure 2A and Figure 5C The nozzle assembly 100 has an air inlet 110 and a liquid inlet 120. The air inlet 110 of the nozzle assembly 100 is connected to the air outlet 220 of the air pump 200 through the air pipe 130 (see Figure 6 ) is connected, the liquid inlet 120 of the nozzle assembly 100 is connected to the control valve outlet 310 of the control valve 300 (see Figure 3A ) are connected.

[0061] When the control valve 300 is in the working state, the liquid flow channel 140 is open; when the control valve 300 is in the non-working state, the liquid flow channel 140 is closed, or the liquid can only flow in one direction from the control valve outlet 310 of the control valve 300 along the liquid flow channel 140 to the nozzle assembly 100.

[0062] The air pump 200 is used to input positive pressure airflow to the air inlet 110 of the nozzle assembly 100. The liquid in the liquid flow channel 140 is sucked into the liquid inlet 120 of the nozzle assembly 100 under the action of the positive pressure airflow. The airflow and the liquid are mixed in the nozzle assembly 100 to form a liquid spray, which is sprayed into the clothing treatment drum 20 of the clothing treatment device (see Figure 1A 、 Figure 1B )Inside.

[0063] In the above embodiment, liquid is drawn into nozzle assembly 100 by airflow, where it mixes with the liquid to form a liquid spray. When control valve 300 (i.e., spray system 10) is not operating, the water passage is sealed or flows in one direction, preventing foreign matter from entering nozzle assembly 100 or control valve 300 from within the laundry treatment device. This reduces the risk of blockage of nozzle assembly 100 or control valve 300, ensuring long-term stable and reliable operation of spray system 10.

[0064] Optionally, in particular with reference to Figure 3B 、 Figure 3C The control valve 300 may include a piston valve 330 for opening or closing a communication passage between the control valve inlet 320 and the control valve outlet 310 of the control valve 300. In the working state of the control valve 300, the piston valve 330 opens the communication passage (see Figure 3C ), thereby making the liquid flow channel 140 conductive. In the non-operating state of the control valve 300, the piston valve 330 closes the communication channel (see Figure 3B ), thereby closing the liquid flow channel 140.

[0065] In the above embodiment, by integrating the piston valve 330 within the control valve 300, the spray system 10 can have fewer components, a high degree of integration, and facilitate spatial layout. The piston valve 330 has a simple structure, small size, reliable performance, and is easy to integrate within the control valve 300.

[0066] The piston valve 330 may include a valve core 331 and a valve seat 332. The valve seat 332 is provided with a passage communicating with the control valve inlet 320. For example, the piston valve 330 may be a solenoid valve.

[0067] Optionally, the control valve 300 may further include a one-way valve mechanism, which may be installed at the control valve inlet 320 or the control valve outlet 310 of the control valve 300 .

[0068] In the above embodiment, the one-way valve mechanism can make the liquid flow only in one direction from the control valve outlet 310 of the control valve 300 along the liquid flow channel 140 to the nozzle assembly 100, thereby preventing foreign matter from entering the nozzle assembly 100 or the control valve 300 from inside the clothing processing device, and reducing the occurrence of clogging of the nozzle assembly 100 or the control valve 300, thereby ensuring that the spray system 10 operates stably and reliably for a long time.

[0069] Alternatively, the control valve 300 may be a multi-channel switching valve, comprising multiple liquid inlets and one air inlet 321, 322, 323. In a specific example, the valve may comprise two liquid inlets and one air inlet. In an operating state, the multi-channel switching valve can switch between connecting its various liquid inlets or air inlets 321, 322, 323 to its control valve outlet 310.

[0070] In the above embodiment, the multi-channel switching valve allows liquid from different liquid inlets to be supplied to the nozzle assembly 100 and then sprayed into the laundry tub 20, enriching the functionality of the laundry treatment apparatus. Furthermore, the multi-channel switching valve can also supply gas from the air inlet to the nozzle assembly 100, allowing gas to flush the pipeline. The use of a multi-channel switching valve reduces the number of components, achieves high integration, and facilitates spatial layout.

[0071] Optionally, refer to Figure 2A The spray system 10 may further include an installation box 400, which includes a plurality of connectors. A plurality of liquid storage containers 410, 420 can be freely installed in the installation box 400 and connected to the plurality of connectors respectively. The plurality of liquid inlets of the multi-channel switching valve are respectively connected to the plurality of connectors.

[0072] In the above embodiment, the spray system 10 can switch between using the liquids in different liquid storage containers 410, 420, and form a spray through the nozzle assembly 100 to spray into the clothing treatment tub 20. The multiple liquid storage containers 410, 420 can be freely installed in the installation box 400, and the liquid can be replaced or added by replacing the liquid storage containers 410, 420. This is convenient to operate, and a wider variety of clothing treatment liquids can be used in a limited space, which is more functional. The multiple liquid storage containers 410, 420 are respectively connected to the multiple connectors of the installation box 400, and the multiple liquid inlets of the multi-channel switching valve are respectively connected to the multiple connectors of the installation box 400. When the liquid storage containers 410, 420 are replaced, the connection status of the multiple liquid inlets of the multi-channel switching valve and the multiple connectors of the installation box 400 is not affected, which makes the operation convenient, the connection at the connector is stable, and leakage is not likely to occur.

[0073] Here, the two liquid storage containers 410 and 420 can have the same or similar structure. The liquid storage containers can be used to store laundry detergent, softener, disinfectant, care agent, water, etc., and can be used or replaced according to actual needs.

[0074] Optionally, refer to Figure 5C and Figure 5DThe nozzle assembly 100 may include a detachably mounted nozzle housing 101, a nozzle head 102, and a nozzle cover 103. The nozzle housing 101 has a housing air channel 1011 and a housing water channel 1012, particularly a straight housing air channel 1011 and a straight housing water channel 1012 arranged in parallel. The nozzle head 102 has a nozzle air channel 1021 and a nozzle water channel 1022, particularly a straight nozzle air channel 1021 and a straight nozzle water channel 1022 arranged in parallel.

[0075] The downstream end of the nozzle water channel 1022 is bent and connected to the nozzle air channel 1021, thereby forming a Venturi tube structure at the downstream end of the nozzle. The nozzle air channel 1021 is connected to the shell air channel 1011, and the nozzle water channel 1022 is connected to the shell water channel 1012.

[0076] The nozzle cover 103 is detachably connected to the nozzle housing 101, and the spray head 102 is positioned between the nozzle cover 103 and the nozzle housing 101. As a preferred example, the nozzle cover 103 can be detachably connected to the nozzle housing 101 by snapping.

[0077] In the above embodiment, the venturi tube structure is formed in the nozzle assembly 100, which can work stably for a long time and is not prone to leakage. The nozzle assembly 100 is a detachable structure, which is easy to process, clean and maintain.

[0078] Alternatively, see 5A to 5D The downstream end face 1023 of the nozzle 102 is a plane, and the nozzle cover 103 includes a protective rib 1031 arranged around the downstream end face 1023. The protective rib 1031 protrudes downstream than the downstream end face 1023, and the protective rib 1031 includes a notch 1032 formed on the lower side thereof.

[0079] A nozzle hole 1024 for spraying a liquid spray may be formed on the downstream end surface 1023. The nozzle hole 1024 may be located at an upper portion of the downstream end surface 1023.

[0080] In the above embodiment, the downstream end face 1023 of the nozzle (the end face from which the liquid spray is ejected) is a plane, and is not prone to accumulation and blockage of lint. The nozzle cover 103 includes a protective rib 1031 arranged around the downstream end face, and the protective rib 1031 protrudes downstream than the downstream end face 1023. The protective rib 1031 can block lint from reaching the downstream end face 1023 (the nozzle hole 1024), further preventing lint accumulation and blockage. The protective rib 1031 includes a notch 1032 formed on its lower side, and even if lint reaches the downstream end face 1023, it is easy to leave the downstream end face 1023 from the notch 1032.

[0081] Optionally, the nozzle assembly 100 may further include a fluid connector 104 and a nozzle filter 150 . The fluid connector 104 may be detachably snap-connected to the nozzle housing 101 , and the nozzle filter 150 is disposed between the fluid connector 104 and the nozzle housing 101 .

[0082] In the above embodiment, the nozzle assembly 100 is provided with a filter in the liquid passage, which can effectively reduce the entry of foreign matter during the use of the nozzle assembly 100, prevent the nozzle from being blocked, and increase the service life of the nozzle.

The air inlet 210 of the air pump 200 is connected to the filter cover 620 through an air intake pipe, so that the air filtered by the air pump filter 610 passes through the air inlet 210 of the air pump 200 (see Figure 6 ) enters the air pump 200.

[0085] In the above embodiment, an air pump filter 610 is installed at the air inlet of the air pump, and a filter cover 620 is installed above the air pump filter 610. This not only filters the air but also effectively prevents the accumulation of foreign matter and impurities on the filter, thereby improving the cleanliness of the clothes processed by the clothing processing device. The air pump 200, control valve 300, and air pump filter 620 are installed on the tray 500, which can achieve modular assembly and convenient installation.

[0086] Optionally, the air pump filter unit 600 may further include a filter holder 630 , which may securely hold the air pump filter 610 within the filter cover 620 .

[0087] Optionally, the tray 500 is installed horizontally, and the tray 500 includes a downwardly arranged air vent, and the air pump filter 610 covers the air vent. When the air pump 200 is working, the air flows through the air vent of the tray 500 and the air pump filter 610 into the air inlet 210 of the air pump 200.

[0088] In the above embodiment, the installation method of the tray 500 is simple, the layout is reasonable, and the gas flow path is simple and reasonable.
