[0076] Background

[0077] Detergent foam can play a good role in cleaning and softening clothes during the washing process. Currently, existing washing machines usually do not have an active foam generating device, and foam can only be generated after washing for a period of time. The detergent takes a long time to take effect, and some detergents cannot be completely dissolved in water, affecting the cleaning effect.

[0078] Example 1

[0079] Based on this, Figure 1-Figure 9 As shown, in a first aspect, embodiment 1 of the present application provides a detergent dispensing assembly for a fabric processing device, and the detergent dispensing assembly 1 comprises:

[0080] The infusion pipeline 100 is used to convey a mixed liquid containing detergent and washing water;

[0081] The jet foaming module 200 includes an ejector 201 connected to the infusion pipeline 100, and an air flow channel 202 connected to the ejector 201. When the mixed liquid in the infusion pipeline 100 flows through the ejector 201, negative pressure can be generated. The gas in the air flow channel 202 can be sucked into the ejector 201 under the action of the negative pressure and mixed with the mixed liquid in the ejector 201 to generate foam.

[0082] The detergent dispensing assembly 1 includes a plurality of jet foaming modules 200, which are connected in parallel to the infusion pipeline 100, and at least one of the plurality of jet foaming modules 200 is also correspondingly provided with a pressure relief valve assembly 300;

[0083] The pressure relief valve assembly 300 is used to be opened when the pressure at the liquid inlet end of the corresponding jet foaming module 200 reaches a preset pressure value, so as to reduce the liquid inlet pressure of the jet foaming module 200 by discharging part of the mixed liquid.

[0084] In the embodiment of the present application, by setting multiple groups of jet foaming modules 200 in parallel on the infusion pipeline 100, the total flow rate of the mixed liquid when flowing through the ejector 201 can be increased, thereby increasing the output of foam. More foam means that the detergent can better cover the clothes and improve the cleaning effect. By using the jet water according to the pressure step, the utilization efficiency of the jet water is improved, and the foaming amount is further increased, making the use of water resources and detergents more efficient. Since the negative pressure generated by the ejector can inhale gas and mix with the mixed liquid to generate foam, this helps to further disperse and dissolve the detergent in the water, thereby improving the efficiency of the use of the detergent. At the same time, the setting of the pressure relief valve assembly can be opened when the pressure at the liquid inlet end of the jet foaming module reaches a preset pressure value, and the liquid inlet pressure is reduced by discharging part of the mixed liquid. This can prevent the equipment from being damaged due to excessive pressure, while also maintaining the stability of foam generation.

[0085] Furthermore, in some possible implementations, the detergent dispensing component 1 further includes:

[0086] The pressure relief pipeline 400, the liquid inlet end of the pressure relief pipeline 400 is connected to the liquid discharge end of the pressure relief valve assembly 300, and the liquid outlet end is connected to the manual delivery device 501 of the fabric processing equipment and / or the manual delivery pipeline 500 of the fabric processing equipment and / or the foam delivery pipeline 600 of the fabric processing equipment and / or the fabric processing cylinder 700 of the fabric processing equipment.

[0087] In the embodiment of the present application, by providing a pressure relief pipeline 400, the mixed liquid discharged from the pressure relief valve assembly 300 can be guided to different parts, such as the manual delivery device 501, the manual delivery pipeline 500, the foam delivery pipeline 600 or the fabric treatment cylinder 700. This design provides flexibility and the flow direction of the pressure relief liquid can be adjusted according to actual needs. By guiding the excess pressure liquid out through the pressure relief pipeline 400, the fabric treatment equipment can be prevented from being damaged due to excessive pressure, thereby extending the service life of the equipment.

[0088] Further, in some possible implementations, each jet foaming module 200 includes at least one ejector 201;

[0089] When the jet foaming module 200 includes a plurality of ejectors 201 , the plurality of ejectors 201 are connected in parallel to the infusion pipeline 100 .

[0090] In the embodiment of the present application, each jet foaming module 200 includes at least one ejector 201. When the jet foaming module 200 includes multiple ejectors 201, these ejectors are connected in parallel on the infusion pipeline 100. This design can increase the total flow rate of the mixed liquid when it flows through the ejector, thereby improving the efficiency of foam generation. The parallel ejectors can distribute the pressure in the infusion pipeline 100 more evenly, reduce the pressure on a single ejector, thereby reducing equipment wear and extending equipment life. At the same time, the parallel ejector design provides redundancy. Even if an ejector fails, other ejectors can still continue to work, ensuring that foam generation will not stop completely, thereby improving the reliability of the system.

[0091] Further, in some possible implementations, such as Figure 1-Figure 3 As shown, the detergent dispensing assembly 1 includes two sets of jet foaming modules 200 connected in parallel on the infusion pipeline 100;

[0092] The two groups of jet foaming modules 200 include a first jet foaming module 200 a close to the upstream of the infusion path of the infusion pipeline 100 , and a second jet foaming module 200 b close to the downstream of the infusion path of the infusion pipeline 100 .

[0093] In the embodiment of the present application, by setting the first jet foaming module 200a upstream and the second jet foaming module 200b downstream, the flow rate and pressure of the mixed liquid in the infusion pipeline 100 can be controlled in steps. This design helps to adjust the generation of foam according to different washing stages and optimize the washing effect. The first jet foaming module 200a can quickly generate foam at the beginning of washing, while the second jet foaming module 200b can further increase the amount of foam or refine the foam structure as needed. This design helps to improve the cleanliness of clothes and the quality of foam. If one group of jet foaming modules fails, the other group can still continue to work, thereby ensuring that foam generation will not stop completely, thereby improving the reliability of the system.

[0094] Further, in some possible implementations, the total flow rate of the first jet foaming module 200a is greater than the total flow rate of the second jet foaming module 200b;

[0095] and / or

[0096] The equivalent nozzle diameter of the first jet foaming module 200a is greater than the equivalent nozzle diameter of the second jet foaming module 200b;

[0097] and / or

[0098] The number of ejectors in the first jet foaming module 200a is greater than the number of ejectors, the equivalent nozzle diameter, and the number of ejectors in the second jet foaming module;

[0099] The equivalent nozzle diameter of the jet foaming module is the total area of ​​the nozzle diameters of all ejectors in the jet foaming module.

[0100] That is, in the embodiment of the present application, water is mainly introduced into and foamed through the first jet foaming module 200a, and the flow rate is relatively large. The second jet foaming module 200b performs auxiliary foaming during pressure relief and drainage to avoid water waste. It is worth noting that the equivalent nozzle diameter refers to the diameter calculated as a circular hole with the total area of ​​all parallel ejector nozzle diameters of the group of jet foaming modules.

[0101] Further, in some possible implementations, such as Figure 1 As shown, the pressure relief valve assembly 300 is a double pressure relief valve assembly with double pressure relief valves, and the double pressure relief valve assembly includes a first pressure relief valve 301 corresponding to the first jet foaming module 200a and a second pressure relief valve 302 corresponding to the second jet foaming module 200b, the first pressure relief valve 301 is arranged at an upstream position of the infusion path between the first jet foaming module 200a and the second jet foaming module 200b, and the second pressure relief valve 302 is arranged at a downstream position of the infusion path close to the second jet foaming module 200b;

[0102] The first pressure relief valve 301 is used to be opened when the pressure at the liquid inlet end of the first jet foaming module 200a reaches a first preset pressure value, so that part of the mixed liquid discharged through the first pressure relief valve 301 enters the second jet foaming module 200b, and the second pressure relief valve 302 is used to be opened when the pressure at the liquid inlet end of the second jet foaming module 200b reaches a second preset pressure value, so that part of the mixed liquid is discharged through the second pressure relief valve 302;

[0103] The first preset pressure value is smaller than the second preset pressure value, and the opening pressure of the first pressure relief valve 301 is smaller than the opening pressure of the second pressure relief valve 302 .

[0104] In the embodiment of the present application, by setting a double pressure relief valve assembly, including a first pressure relief valve 301 and a second pressure relief valve 302, a more precise control of the pressure of the two groups of jet foaming modules can be achieved. This design helps to adjust the pressure according to different washing stages and needs and optimize the washing effect. The different setting positions and preset pressure values ​​of the first pressure relief valve 301 and the second pressure relief valve 302 allow the system to work under different pressure gradients, ensuring that appropriate pressures can be maintained at different washing stages to avoid damage to the equipment caused by excessive pressure. When the pressure at the liquid inlet end of the first jet foaming module 200a reaches the first preset pressure value, the first pressure relief valve 301 opens to prevent the upstream pressure from being too high. Similarly, the second pressure relief valve 302 opens when the pressure at the liquid inlet end of the second jet foaming module 200b reaches the second preset pressure value to prevent the downstream pressure from being too high. Part of the mixed liquid discharged by the first pressure relief valve 301 enters the second jet foaming module 200b, which helps to balance the pressure and flow between the two groups of modules. The second pressure relief valve 302 directly discharges part of the mixed liquid to further adjust the downstream pressure and flow. The design of double pressure relief valves improves the reliability of the system. Even if one module has a problem, the other module can still work. At the same time, the pressure relief valve can prevent the system from being damaged due to excessive pressure.

[0105] Further, in some possible implementations, such as Figure 1 As shown, the ejector 201 in the first jet foaming module 200a includes a first ejector A201a and a first ejector B201b connected in parallel on the infusion pipeline;

[0106] The specifications of the ejector 201 in the first jet foaming module 200a are the same as those in the second jet foaming module 200b.

[0107] In the embodiment of the present application, the ejector in the first jet foaming module 200a and the ejector in the second jet foaming module 200b adopt the same specifications, which facilitates standardization on the one hand, and on the other hand, the first jet foaming module 200a is connected in parallel through the ejectors to form an equivalent nozzle aperture larger than the second jet foaming module 200b, a larger jet flow rate and a larger foaming amount.

[0108] Specifically, Figure 1 As shown, when the pressure of the foaming water containing detergent delivered by the infusion pipeline 100 is less than the opening pressure of the first pressure relief valve 301, the first pressure relief valve 301 is closed, and all the foaming water is foamed by the first jet foaming module 200a, and then passes through the foam delivery pipeline 600 and the foam nozzle located at the top of the door seal, and is sprayed into the fabric treatment cylinder 700.

[0109] More specifically, Figure 1As shown, when the foaming water pressure of the infusion pipeline 100 is greater than the opening pressure of the first pressure relief valve 301, the first pressure relief valve 301 opens, and a part of the foaming water is foamed through the second jet foaming module 200b, merges with the foam generated by the first jet foaming module 200a, and then is sprayed into the fabric treatment cylinder 700 through the foam delivery pipeline 600 and the foam nozzle.

[0110] More specifically, Figure 1 As shown, when the inlet pressure of the second jet foaming module 200b is greater than the second pressure relief valve 302, a portion of the washing water is diverted to the pressure relief pipeline 400, and finally flows into the fabric treatment drum 700 through the manual delivery device 501 connected to the pressure relief pipeline 400 and / or the manual delivery pipeline 500 and / or the foam delivery pipeline 600 and / or the fabric treatment drum 700.

[0111] Preferably, the pressure relief pipeline 400 is connected to the manual delivery device 501 of the manual delivery pipeline 500 .

[0112] Further, in some possible implementations, such as Figure 4 and Figure 5 As shown, the ejector 201 includes an ejector inlet 2011, an ejector outlet 2012, and an ejector tube section 2013 formed between the ejector inlet 2011 and the ejector outlet 2012;

[0113] The jet pipe section 2013 includes a contraction section 20131, a throat section 20132 and a diffusion section 20133 connected between the ejector inlet 2011 and the ejector outlet 2012;

[0114] The air flow channel 202 is connected to the throat section 20132 of the jet pipe section 2013.

[0115] The ejector 201 in the embodiment of the present application is provided with an ejector inlet 2011, a contraction section 2012131, a throat 20132, a diffusion section 20133 and an ejector outlet 2012 in sequence from the water inlet end. In this way, when the mixed liquid of washing water and detergent is ejected through the nozzle of the ejector 201, a local negative pressure can be generated, and gas can be sucked from the air flow channel 202 to generate foam.

[0116] Preferably, the pressure relief valve is integrated and installed on the side wall partition of the ejector, and the direction of the pressure relief water flow is perpendicular to the partition wall. The shape of the ejector nozzle can be determined by the protruding structures of the top surface, bottom surface, and side wall surrounding and cooperating with each other in the direction of the jet center, preferably a circular hole. Preferably, the infusion pipeline 100 and the integrated jet foaming module 200 are formed by docking and splicing the upper cover 10a and the lower cover 10b constituting the top cover 10 of the detergent box, and the two can be formed into a whole by welding or other fixing methods. The integration method of the ejector 201, the pressure relief valve assembly 300 and the infusion pipeline 100 is as follows: Figure 6-Figure 9 shown.

[0117] Further, in some possible implementations, such as Figure 6-Figure 9 As shown, the detergent dispensing component 1 includes:

[0118] A detergent box, wherein an opening is formed at the top of the detergent box;

[0119] A detergent box top cover 10, which is disposed at the opening of the detergent box and is used to seal the detergent box;

[0120] A liquid infusion pipeline 100 and a jet foaming module 200 are formed inside the top cover of the detergent box.

[0121] Further, in some possible implementations, such as Figure 6-Figure 9 As shown, the detergent box cover 10 includes a flat upper cover 10 a and a lower cover 10 b , which are pressed together to define a liquid infusion pipeline 100 and a jet foaming module 200 .

[0122] It is worth mentioning that in the embodiment of the present application, the infusion pipeline 100 and the jet foaming module 200 are defined by pressing the flat upper cover 10a and the lower cover 10b together, so that the detergent dispensing component 10 can have a good foaming effect while avoiding the detergent dispensing component from being larger in size. At the same time, the pressure relief valve assembly 300 arranged in the detergent top cover 10 can also effectively release the large pressure in the detergent top cover 10, thereby avoiding the problem of excessive pressure due to the small space inside the detergent box top cover 10, thereby avoiding the risk of the detergent box top cover 10 bursting due to excessive pressure in the detergent box top cover 10.

[0123] Further, in some possible implementations, such as Figure 1-Figure 3 As shown, the detergent dispensing component 10 also includes:

[0124] The ozone generating module 800 is connected to the air flow channel 200 so that the ozone gas in the air flow channel 200 can be sucked into the ejector 201 under the action of negative pressure and mixed with the mixed liquid in the ejector 201 to generate foam containing ozone gas.

[0125] In the embodiment of the present application, by providing an ozone generating module 800, ozone gas can be introduced into the detergent dispensing component 10 while foaming, so that it adheres to the surface of the foam film and is wrapped inside the foam, forming a high-concentration ozone foam, which has good sterilization, enhanced cleaning, soft protection, and anti-coloring effects. At the same time, in the embodiment of the present application, by integrating the ozone generating module 800 into the detergent dispensing component, the overall design of the device can be simplified and the need for additional equipment can be reduced.

[0126] Specifically, Figure 1-Figure 3 As shown, the ozone generating module 800 includes an ozone generator 801 and an air pipe 802, and the ozone generator 801 is connected with the air flow channel 200 through the air pipe 802;

[0127] An air intake check valve 803 is provided on the air pipe 802 , and the air intake check valve 803 is designed to allow the fluid to flow out of the ozone generator 801 and restrict the fluid from flowing back to the ozone generator 801 .

[0128] In the embodiment of the present application, the design of the air pipe 802 and the air intake check valve 803 can accurately control the ozone flow rate flowing out of the ozone generator 801, ensuring a stable supply of ozone gas in the air flow channel 200. The design of the air intake check valve 803 allows the fluid to flow out of the ozone generator 801 while limiting the fluid from flowing back to the ozone generator 801, which prevents backflow and ensures the safety and reliability of the system.

[0129] Further, in some possible implementations, the detergent delivery component further includes:

[0130] A foam delivery pipeline 600 and a manual delivery pipeline 500, wherein the foam delivery pipeline 600 is used to deliver foam to a fabric treatment drum 700 of the fabric treatment device, and the manual delivery pipeline 500 is used to manually deliver detergent and washing water to the fabric treatment drum 700 of the fabric treatment device through a manual delivery device 501;

[0131] The liquid inlet end of the foam delivery pipeline 600 is connected to the liquid outlet end of the jet foaming module 200, and the liquid discharge end is connected to the fabric treatment drum 700 of the fabric treatment device. The manual delivery pipeline 500 is connected to the pressure relief pipeline 400 of the detergent delivery component.

[0132] Furthermore, the second aspect of the embodiment of the present application also provides a fabric processing device, which includes a fabric processing drum 700 and the detergent dispensing assembly 1 provided in the first aspect of the embodiment of the present application.

[0133] Specifically, when the detergent is automatically dispensed, the automatic dispensing water inlet valve is opened, and the washing water enters the automatic detergent dispensing device. At the same time, the detergent dispensing pump is turned on to pump out the detergent in the detergent storage chamber according to the set dispensing amount. Under the impact of the washing water, the detergent enters the detergent mixing chamber for mixing and dissolving, and then is supplied to the jet foaming module 200 through the infusion pipeline 100. The manual detergent dispensing device includes a manual dispensing water inlet valve, a manual detergent dispensing device, and a manual dispensing washing water delivery pipeline. When the detergent is manually dispensed, the manual dispensing water inlet valve is opened, and the washing water enters the manual detergent dispensing device to rinse the manually dispensed detergent therein, and after mixing and dissolving, it is dispensed into the fabric treatment drum 700 through the manual dispensing washing water delivery pipeline.

[0134] Example 2

[0135] The difference between this embodiment and embodiment 1 is that Figure 2 and Figure 3 As shown, the pressure relief valve assembly 300 in the embodiment of the present application includes a single pressure relief valve assembly having a single pressure relief valve;

[0136] The single pressure relief valve assembly includes a first pressure relief valve 301 corresponding to the first jet foaming module 200a. The first pressure relief valve 301 is arranged at an upstream position of the infusion path between the first jet foaming module 200a and the second jet foaming module 200b, and is used to be opened when the pressure at the liquid inlet end of the first jet foaming module 200a reaches a first preset pressure value, so as to discharge part of the mixed liquid into the second jet foaming module 200b for foaming.

[0137] or

[0138] The single pressure relief valve assembly includes a second pressure relief valve 302 arranged corresponding to the second jet foaming module 200b, and the second pressure relief valve 302 is arranged at a downstream position of the infusion path close to the second jet foaming module 200b, and is used to be opened when the pressure at the liquid inlet end of the second jet foaming module 200b reaches a second preset pressure value, so as to discharge part of the mixed liquid into the pressure relief pipeline 400 through the second pressure relief valve 302;

[0139] The first preset pressure value is smaller than the second preset pressure value, and the opening pressure of the first pressure relief valve 301 is smaller than the opening pressure of the second pressure relief valve 302 .

[0140] Specifically, when all parallel ejectors work at the same time, if the water pressure at the front end of the ejector is less than the set value P3, the second pressure relief valve 302 can be cancelled. The set value P3 is preferably in the range of 0.10Mpa-0.2Mpa. Figure 2 shown.

[0141] Of course, the first pressure relief valve 301 between the two groups of jet foaming modules can also be removed. In this case, the ejectors in the two groups of jet foaming modules use the same specifications and quantity. This can achieve a more delicate foaming effect and a larger foam output than a single group of ejectors. Figure 3 shown.

[0142] It should be noted that the ejector 201 in this embodiment and embodiment 1 preferably has a rectangular internal channel cross-section, the structure of the top and bottom surfaces borrows the top and bottom surfaces of the detergent mixing chamber, and the side walls of the ejector are formed by setting partitions perpendicular to the top and bottom surfaces.
