[0076] Background Introduction

[0077] Detergent foam plays a good role in cleaning and softening clothes during the washing process. Currently, most washing machines do not have an active foam generator, so foam is only produced after a period of washing. This results in a slower detergent effect, and some detergent may not completely dissolve in the water, affecting the cleaning effect.

[0078] Example 1

[0079] Based on this, such as Figures 1-9 As shown, in the first aspect of this application, a detergent dispensing assembly is provided for a fabric treatment device. The detergent dispensing assembly 1 includes:

[0080] Infusion line 100, used to deliver a mixture of detergent and washing water;

[0081] The jet foaming module 200 includes a jet injector 201 connected to the infusion line 100 and an airflow channel 202 connected to the jet injector 201. When the mixed liquid in the infusion line 100 flows through the jet injector 201, it can generate negative pressure. The gas in the airflow channel 202 can be drawn into the jet injector 201 under the action of negative pressure and mix with the mixed liquid in the jet injector 201 to generate foam.

[0082] The detergent dispensing assembly 1 includes multiple sets of jet foaming modules 200, which are connected in parallel on the infusion line 100, and at least one of the multiple sets of jet foaming modules 200 is also equipped with a pressure relief valve assembly 300.

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

[0084] In the embodiments of the present application, by arranging multiple sets of jet foaming modules 200 in parallel on the liquid conveying pipeline 100, the total flow rate of the mixed liquid flowing through the jet 201 can be increased, thereby improving the production of foam. More foam means that the detergent can better cover the laundry, improving the cleaning effect. By using jet water according to pressure steps, the utilization efficiency of jet water is improved, further increasing the foaming amount, making the use of water resources and detergents more efficient. Since the negative pressure generated by the jet can suck in gas and mix with the mixed liquid to generate foam, this helps to further disperse and dissolve the detergent in water, improving the efficiency of the detergent. At the same time, the arrangement of the pressure relief valve assembly can open when the pressure at the liquid inlet end of the jet foaming module reaches the preset pressure value, thereby reducing the liquid inlet pressure by discharging part of the mixed liquid. In this way, the equipment can be prevented from being damaged due to excessive pressure, and the stability of foam generation can also be maintained.

[0085] Further, in some possible implementations, the detergent dispensing assembly 1 further comprises:

[0086] A pressure relief pipeline 400, the liquid inlet end of the pressure relief pipeline 400 is communicated with the liquid outlet end of the pressure relief valve assembly 300, the liquid outlet end is communicated with the manual dispensing device 501 of the fabric treatment equipment and / or communicated with the manual dispensing pipeline 500 of the fabric treatment equipment and / or communicated with the foam conveying pipeline 600 of the fabric treatment equipment and / or communicated with the fabric treatment drum 700 of the fabric treatment equipment.

[0087] In the embodiments of the present application, by arranging the pressure relief pipeline 400, the mixed liquid discharged by the pressure relief valve assembly 300 can be guided to different parts, such as the manual dispensing device 501, the manual dispensing pipeline 500, the foam conveying pipeline 600 or the fabric treatment drum 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 prolonging the service life of the equipment.

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

[0089] When the jet foaming module 200 comprises multiple jets 201, the multiple jets 201 are connected in parallel on the liquid conveying pipeline 100.

[0090] The jet flow foaming module 200 in the embodiments of the present application comprises at least one jet flow device 201. When the jet flow foaming module 200 comprises a plurality of jet flow devices 201, the jet flow devices are connected in parallel on the liquid conveying pipeline 100. This design can increase the total flow of the mixed liquid flowing through the jet flow device, thereby improving the generation efficiency of the foam. The parallel jet flow devices can more evenly distribute the pressure in the liquid conveying pipeline 100, thereby reducing the pressure borne by a single jet flow device, reducing equipment wear and tear, and prolonging the service life of the equipment. At the same time, the parallel jet flow device design provides redundancy, so that even if a jet flow device fails, other jet flow devices can still continue to work, ensuring that foam generation does not completely stop, thereby improving the reliability of the system.

[0091] Further, in some possible embodiments, as shown in FIG. 1, the detergent dispensing assembly 1 comprises two groups of jet flow foaming modules 200 connected in parallel on the liquid conveying pipeline 100. Figures 1-3

[0092] The two groups of jet flow foaming modules 200 comprise a first jet flow foaming module 200a close to the upstream of the liquid conveying path of the liquid conveying pipeline 100 and a second jet flow foaming module 200b close to the downstream of the liquid conveying path of the liquid conveying pipeline 100.

[0093] In the embodiments of the present application, by arranging the first jet flow foaming module 200a upstream and the second jet flow foaming module 200b downstream, the flow and pressure of the mixed liquid in the liquid conveying pipeline 100 can be controlled in stages. This design helps to adjust the generation of foam according to different washing stages, thereby optimizing the washing effect. The first jet flow foaming module 200a can quickly generate foam at the initial stage of washing, and the second jet flow foaming module 200b can further increase the amount of foam or refine the foam structure as needed. This design helps to improve the cleaning degree of the laundry and the quality of the foam. If one group of jet flow foaming modules fails, the other group can still continue to work, thereby ensuring that foam generation does not completely stop, thereby improving the reliability of the system.

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

[0095] And / or

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

[0097] And / or

[0098] The number of jet flow devices of the first jet flow foaming module 200a is greater than the number of jet flow devices of the second jet flow foaming module, the equivalent nozzle diameter, and the number of jet flow devices.

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

[0100] That is, in the embodiment, the first jet foaming module 200a is mainly used for water foaming, and has a large flow rate. The second jet foaming module 200b is used for auxiliary foaming when pressure relief and drainage, so as to avoid water waste. It is worth noting that the equivalent nozzle diameter refers to the diameter of a circular hole calculated by the total area of the nozzle diameters of all the jets in parallel in the jet foaming module.

[0101] Further, in some possible embodiments, as shown in Figure 1 The pressure relief valve assembly 300 is a double pressure relief valve assembly with double pressure relief valves. The double pressure relief valve assembly includes a first pressure relief valve 301 arranged corresponding to the first jet foaming module 200a and a second pressure relief valve 302 arranged corresponding to the second jet foaming module 200b. The first pressure relief valve 301 is arranged at a position upstream of the infusion path between the first jet foaming module 200a and the second jet foaming module 200b. The second pressure relief valve 302 is arranged at a position downstream 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 liquid inlet end pressure 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. The second pressure relief valve 302 is used to be opened when the liquid inlet end pressure 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 less than the second preset pressure value, and the opening pressure of the first pressure relief valve 301 is less than the opening pressure of the second pressure relief valve 302.

[0104] In this embodiment, a dual pressure relief valve assembly, including a first pressure relief valve 301 and a second pressure relief valve 302, allows for more precise control of the pressure in the two sets of jet foaming modules. This design helps adjust the pressure according to different washing stages and needs, optimizing the washing effect. The different positions and preset pressure values ​​of the first and second pressure relief valves 301 and 302 allow the system to operate under different pressure gradients, ensuring that appropriate pressure is maintained in different washing stages and preventing damage to the equipment from excessive pressure. When the pressure at the inlet of the first jet foaming module 200a reaches the first preset pressure value, the first pressure relief valve 301 opens to prevent excessive upstream pressure. Similarly, the second pressure relief valve 302 opens when the pressure at the inlet of the second jet foaming module 200b reaches the second preset pressure value to prevent excessive downstream pressure. Part of the mixed liquid discharged by the first pressure relief valve 301 enters the second jet foaming module 200b, helping to balance the pressure and flow between the two modules. The second pressure relief valve 302 directly discharges part of the mixed liquid, further regulating the downstream pressure and flow. The dual pressure relief valve design improves system reliability, ensuring that even if one module malfunctions, the other can still function, while the pressure relief valves prevent system damage due to excessive pressure.

[0105] Furthermore, 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 line;

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

[0107] In this embodiment, by using the same specifications for the jet injector in the first jet foaming module 200a and the jet injector in the second jet foaming module 200b, it is convenient to achieve generalization. On the other hand, the first jet foaming module 200a forms a larger equivalent nozzle diameter, a larger jet flow rate, and a larger foaming amount than the second jet foaming module 200b through the parallel connection of the jet injectors.

[0108] Specifically, such as 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 sprayed into the fabric treatment cylinder 700 through the foam delivery pipeline 600 and the foam nozzle located on the top of the door seal.

[0109] More specifically, such as 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 is opened, and a part of the foaming water is shunted to the second jet foaming module 200b to be foamed, and the foam generated by the first jet foaming module 200a is merged, and then sprayed into the fabric treatment cylinder 700 through the foam delivery pipeline 600 and the foam spray head.

[0110] More specifically, as shown in 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 part of the washing water is shunted to the pressure relief pipeline 400, and finally flows into the fabric treatment cylinder 700 through the manual dispensing device 501 and / or the manual dispensing pipeline 500 and / or the foam delivery pipeline 600 and / or the fabric treatment cylinder 700.

[0111] Preferably, the pressure relief pipeline 400 is in communication with the manual dispensing device 501 of the manual dispensing pipeline 500.

[0112] Further, in some possible embodiments, as shown in Figure 4 and Figure 5 The jet device 201 includes a jet device inlet 2011, a jet device outlet 2012, and a jet pipe section 2013 formed between the jet device inlet 2011 and the jet device outlet 2012.

[0113] The jet pipe section 2013 includes a contraction section 20131, a throat section 20132, and a diffusion section 20133 in communication between the jet device inlet 2011 and the jet device outlet 2012.

[0114] The airflow channel 202 is in communication with the throat section 20132 of the jet pipe section 2013.

[0115] The jet device 201 in the embodiment of the present application is sequentially provided with the jet device inlet 2011, the contraction section 20131, the throat 20132, the diffusion section 20133, and the jet device outlet 2012 from the water inlet end. In this way, when the mixed solution of washing water and detergent is jetted through the nozzle of the jet device 201, local negative pressure can be generated, and air can be sucked from the airflow channel 202 to generate foam.

[0116] Preferably, the pressure relief valve is integrated on the side wall partition of the fluidic device, and the direction of the pressure relief water flow is perpendicular to the partition wall. The shape of the nozzle of the fluidic device can be determined by the convex structure of the top surface, the bottom surface and the side wall towards the center of the jet, and is preferably a circular orifice. Preferably, the infusion pipeline 100 and the integrated fluidic foaming module 200 are formed by the upper cover 10a and the lower cover 10b of the detergent box top cover 10, and the two can be formed into a whole by welding or other fixing methods. The integrated mode of the fluidic device 201, the pressure relief valve assembly 300 and the infusion pipeline 100 is as shown in Figures 6-9 .

[0117] Further, in some possible embodiments, as shown in Figures 6-9 , the detergent dispensing assembly 1 comprises:

[0118] a detergent box, and an opening is formed at the top of the detergent box;

[0119] a detergent box top cover 10 arranged at the opening of the detergent box for sealing the detergent box;

[0122] It is worth noting that in the embodiments of the present application, the flat upper cover 10a and the lower cover 10b are pressed together to define the infusion pipeline 100 and the fluidic foaming module 200, which can achieve good foaming effect of the detergent dispensing assembly 1 while avoiding large size of the detergent dispensing assembly, and the pressure relief valve assembly 300 arranged in the detergent top cover 10 can also effectively relieve the large pressure in the detergent top cover 10, thereby avoiding the problem of excessive pressure caused by the small space inside the detergent top cover 10, and avoiding the risk of explosion of the detergent top cover 10 caused by excessive pressure in the detergent top cover 10.

[0123] Further, in some possible embodiments, as shown in Figures 1-3 , the detergent dispensing assembly 1 further comprises:

[0124] an ozone generation module 800, which communicates with the airflow channel 202, so that the ozone gas in the airflow channel 202 can be sucked into the fluidic device 201 under the action of negative pressure, and mixed with the mixed liquid in the fluidic device 201 to generate foam containing ozone gas.

[0125] In the embodiment of the present application, the ozone generation module 800 is arranged, so that ozone gas can be introduced while the detergent dispensing assembly 1 is foaming, and the ozone gas can be attached to the surface of the foam film and wrapped inside the foam, forming high-concentration ozone foam, which has good sterilization, enhanced cleaning, soft protection, and anti-color bleeding effects. In the embodiment of the present application, the ozone generation module 800 is integrated into the detergent dispensing assembly, which can simplify the overall design of the equipment and reduce the need for additional equipment.

[0127] The gas pipe 802 is provided with an air inlet one-way valve 803, which is designed to allow fluid to flow out of the ozone generator 801 and limit fluid flow back to the ozone generator 801.

[0128] In the embodiment of the present application, the ozone flow from the ozone generator 801 can be accurately controlled through the design of the gas pipe 802 and the air inlet one-way valve 803, and the stable supply of ozone gas in the gas flow channel 202 is ensured. The design of the air inlet one-way valve 803 allows fluid to flow out of the ozone generator 801 while limiting fluid flow 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 dispensing assembly further comprises:

[0130] a foam delivery pipeline 600 for delivering foam to the fabric treatment drum 700 of the fabric treatment equipment, and a manual dispensing pipeline 500 for manually dispensing detergent and washing water into the fabric treatment drum 700 of the fabric treatment equipment through a manual dispensing device 501;

The manual dispensing device comprises a manual dispensing water inlet valve, a manual dispensing device, and a manual dispensing water delivery pipeline. When the detergent is manually dispensed, the manual dispensing water inlet valve is opened, the washing water enters the manual dispensing device, and the manually dispensed detergent is washed and mixed and dissolved, and then supplied to the fabric treatment drum 700 through the manual dispensing water delivery pipeline.

[0134] Embodiment 2

[0135] The difference between this embodiment and embodiment 1 is that, as shown in Figure 2 and Figure 3 The pressure relief valve assembly 300 in the embodiment of the application comprises a single pressure relief valve assembly with a single pressure relief valve.

[0136] The single pressure relief valve assembly comprises a first pressure relief valve 301 arranged corresponding to the first jet foaming module 200a, which is arranged at a position upstream of the liquid delivery 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] Alternatively

[0138] The single pressure relief valve assembly comprises a second pressure relief valve 302 arranged corresponding to the second jet foaming module 200b, which is arranged at a position downstream of the liquid delivery 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 through the second pressure relief valve 302 into the pressure relief pipeline 400.

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

[0140] Specifically, when all the parallel jet foaming modules work at the same time, the water pressure at the front end of the jet foaming module is less than the set value P3, and the second pressure relief valve 302 can be cancelled. The set value P3 is preferably in the range of 0.10-0.2 MPa, as shown in Figure 2 .

[0141] Of course, the first pressure relief valve 301 between the two groups of jet foaming modules can also be cancelled, at which time the jets in the two groups of jet foaming modules adopt the same specifications and quantities. A more delicate foaming effect and greater foam yield than a single group of jets can be achieved, such as Figure 3

[0142] It should be noted that the jet 201 in the present embodiment and the embodiment 1 preferably has a rectangular internal passage cross section, and the top surface and the bottom surface are borrowed from the top surface and the bottom surface of the detergent mixing cavity, and the side wall of the jet is formed by setting a partition plate perpendicular to the top surface and the bottom surface.
