[0056] Background

[0057] The prior art has a micro foam generator arranged at the water inlet and outlet of the detergent box, but the mixed washing water containing detergent flows into the washing tub faster, and less water is used for foaming, resulting in a small amount of foaming, and part of the detergent is flushed into the tub. The detergent concentration in the foamed detergent water is low, and the foam density is small.

[0058] Based on this, Figure 1-Figure 9 As shown, an embodiment of the present application provides a fabric processing device, comprising:

[0059] Fabric treatment drum 100;

[0060] The detergent box 200 and the liquid mixing box 300, the liquid mixing box 300 includes a liquid mixing chamber 301 with a built-in foaming device 302, the liquid mixing chamber 301 is connected between the detergent box 200 and the fabric treatment drum 100 through a connecting pipe 400, and the connecting pipe 400 includes a liquid inlet pipe 401 connected between the liquid mixing chamber 301 and the detergent box 200, and a bubble discharge pipe 402 connected between the liquid mixing chamber 301 and the fabric treatment drum 100;

[0061] A flow channel connecting the detergent storage chamber and the main water pipeline 600 is provided inside the detergent box 200. The detergent storage chamber and the flow channel are connected by a delivery pump 700, so that a fixed amount of detergent is pumped into the flow channel by the delivery pump 700. The main water pipeline 600 is used to inject a fixed amount of washing water into the flow channel. The liquid inlet pipe 401 is connected to the flow channel in the detergent box 200.

[0062] The washing water injected into the flow channel can flush the detergent pumped into the flow channel toward the liquid inlet pipe 401, and flow into the mixing chamber 301 through the liquid inlet pipe 401 for mixing, so that the washing liquid and the washing water are mixed into a mixed liquid in the mixing chamber 301, the foaming device 302 in the mixing chamber 301 is used to foam the mixed liquid, and the bubble discharge pipe 402 is used to discharge the foam generated in the mixing chamber 301 into the fabric treatment drum 100.

[0063] In the embodiment of the present application, a mixing chamber 301 having a foamer 302 is provided between the detergent box 200 and the fabric treatment drum 100, so that the detergent and the washing water can be fully mixed in the mixing chamber 301 and then foamed, so as to improve the foam effect entering the fabric treatment drum 100.

[0064] It should be noted that, in some alternative embodiments, a water storage chamber may be provided between the detergent box 200 and the liquid mixing chamber 301 for initial mixing of detergent and washing water before the detergent and washing water enter the liquid mixing chamber 301 .

[0065] It should also be noted that in the embodiment of the present application, a flow channel is provided in the detergent box, and a fixed amount of detergent in the detergent storage chamber is pumped into the flow channel through the delivery pump 700, so that a quantitative delivery effect of the detergent can be achieved. At the same time, a fixed amount of washing water is injected into the flow channel in the detergent box 200 through the main water pipeline 600. On the one hand, a precise ratio of detergent and washing water can be achieved. On the other hand, by injecting washing water into the flow channel, the detergent pumped into the flow channel can be flushed into the mixing liquid chamber 301 through the liquid inlet pipe 401 for full mixing, thereby preventing sticky detergent from adhering to the flow channel in the detergent box 200, thereby achieving full mixing of the detergent and washing water in the mixing liquid chamber 301 with a precise ratio, thereby improving the foaming effect of the two after mixing.

[0066] Furthermore, in some possible implementations, a liquid inlet valve is provided on the liquid inlet pipe 401, and the detergent box 200 and the liquid mixing chamber 301 can be connected and disconnected by controlling the opening and closing of the liquid inlet valve.

[0067] In the embodiment of the present application, a liquid inlet valve is provided on the liquid inlet pipe 401 , so that the washing liquid and the washing water can be fully mixed in the liquid mixing chamber 301 .

[0068] Specifically, when the foam washing program is required, the dosing pump 700 first puts detergent into the mixing chamber 301, then controls the opening time of the main wash water inlet valve of the main water pipeline 600 or the liquid level detection device to control the inlet of a small amount of water to mix into high-concentration washing water, closes the inlet valve on the inlet pipe 401 after the water is inlet, and then introduces air or ozone gas into the foaming device 302 in the mixing chamber 301 through the external air pump 901 and / or the ozone generator 902, and foams in the mixing chamber 301, and the foam enters the fabric treatment drum 100 from the door seal through the bubble discharge pipe 402 to perform foam washing on the clothes; when the foam washing program is not required, water is normally inlet, and due to the large amount of water, the water flow fills the mixing chamber 301 and overflows from the overflow pipe 800 and the bubble discharge pipe 402 into the fabric treatment drum 100 to perform normal washing on the clothes. In this way, the mixing chamber 301 is set and controlled to achieve the water inlet switching between foam washing and normal washing, and the dual-action function. Ensure the foaming amount and speed without affecting the normal water inlet.

[0069] It is worth noting that, in some alternative implementations, the design of the overflow pipe 800 may also be eliminated.

[0070] It should be noted that, after the overflow pipe 800 is removed, the mixed liquid chamber 301 only enters water and foam into the door seal through the bubble discharge pipe 402. At this time, the diameter of the bubble discharge pipe 402 can be appropriately increased. For example, the original outer diameter of the bubble discharge pipe 402 can be selected to be 12mm-15mm, and the diameter of the bubble discharge pipe 402 after the diameter is increased can be selected to be 25mm-40mm, preferably 30mm-35mm, to ensure the water inlet speed.

[0071] Further, in some possible implementations, the foamer 302 is disposed at the bottom of the liquid mixing chamber 301;

[0072] The connecting positions of the liquid inlet pipe 401 and the bubble discharge pipe 402 with the liquid mixing chamber 301 are all higher than the setting position of the bubbler 302 .

[0073] In the embodiment of the present application, the foamer 302 is arranged at the bottom of the liquid mixing chamber 301, which can ensure that the detergent and water first contact the foamer 302 after entering the liquid mixing chamber 301, so that the mixing and foaming process starts immediately. This layout helps to improve the uniformity and foaming efficiency of the mixed liquid. Since the position of the liquid inlet pipe 401 and the bubble discharge pipe 402 is higher than the foamer 302, the mixed liquid will naturally flow to the foamer 302 after flowing into the liquid mixing chamber 301. Such a design can use gravity to assist the contact between the mixed liquid and the foamer 302, reduce the energy required to pump the mixed liquid, and improve energy efficiency.

[0074] Furthermore, in some possible embodiments, a plurality of bubblers 302 are provided, and the plurality of bubblers 302 are all arranged at the bottom of the mixing liquid chamber 301 , and the connecting positions of the liquid inlet pipe 401 and the bubble discharge pipe 402 and the mixing liquid chamber 301 are all arranged at the top of the mixing liquid chamber 301 .

[0075] In the embodiment of the present application, multiple foamers 302 are arranged at the bottom of the mixed liquid chamber 301 to increase the foaming area, thereby improving the foaming efficiency and the uniformity of foam generation. This layout helps to form more uniform foam in the entire mixed liquid chamber 301. Multiple foamers 302 can work simultaneously, so that the detergent and water are mixed more quickly and evenly in the mixed liquid chamber 301, thereby improving the washing efficiency. The liquid inlet pipe 401 and the bubble discharge pipe 402 are arranged at the top of the mixed liquid chamber 301, which can ensure that the mixed liquid is injected from the top, while the foam is generated from the bottom and fills the entire mixed liquid chamber 301 upward, and finally discharged from the top. This design helps to achieve continuous generation and discharge of foam, reduce the residence time of foam in the mixed liquid chamber 301, and improve the continuity and efficiency of the washing process. Since the foam is generated from the bottom and discharged upward, this layout can reduce the contact between the foam and the wall of the mixed liquid chamber 301 during the rising process, thereby reducing the rupture and loss of the foam and maintaining the stability of the foam.

[0076] Preferably, the foamer 301 is a hollow component with dense pores on the peripheral wall. Further preferably, there are two or three foamers 302, which can increase the foaming area and accelerate the foaming effect. A liquid level detection probe (not shown in the figure) can also be set in the mixing chamber 301 to control the water level of the foam washing water inlet.

[0077] Further, in some possible implementations, the outlet of the bubble drain pipe 402 is connected to the top of the door seal of the fabric treatment cylinder 100, and a flow guide structure is provided at the outlet of the bubble drain pipe 402;

[0078] The foam discharged from the outlet of the bubble discharge pipe 402 can be guided to the interior of the fabric treatment cylinder 100 through the guide structure.

[0079] In the embodiment of the present application, the outlet of the bubble discharge pipe 402 is arranged at the top of the door seal of the fabric treatment drum 100, and a flow guide structure is provided, so that the position and direction of the foam entering the fabric treatment drum 100 can be accurately controlled, ensuring that the foam is evenly distributed on the clothes, thereby improving the washing effect. Through the design of the flow guide structure, the loss and waste of foam in the discharge process can be reduced, the utilization rate of the foam can be improved, and more foam can reach the surface of the clothes, thereby enhancing the washing effect.

[0080] Further, in some possible implementations, the flow guiding structure includes a flow guiding nozzle 500 disposed at the outlet of the bubble discharge pipe 402:

[0081] The diversion nozzle 500 is designed such that the foam diverted by the diversion nozzle 500 can be sprayed into the fabric processing drum 100 in a waterfall shape.

[0082] In the embodiment of the present application, the design of the guide nozzle 500 allows the foam to be sprayed in a waterfall shape, which can increase the coverage area of ​​the foam on the clothes and improve the uniformity and effect of washing. The foam sprayed in a waterfall shape can penetrate deeper into the fibers of the clothes, which helps to remove stains and bacteria more effectively. The waterfall-shaped spray formed by the guide nozzle 500 can make the washing liquid more evenly distributed in the fabric treatment drum 100, reduce the local accumulation of the washing liquid, and improve the washing efficiency. At the same time, the foam sprayed in a waterfall shape is less likely to splash than the foam discharged directly, which reduces the loss of foam during the discharge process and improves the utilization rate of the foam.

[0083] Specifically, in some possible implementations, the flow guide nozzle 500 includes a mounting section 501, a pressure changing section 502, and a diffusion section 503 which are connected in sequence;

[0084] The mounting section 501 is arranged on the mounting hole of the door seal, the pressure-changing section 502 is a first variable-diameter pipe section whose diameter gradually becomes smaller along the foam flow direction and bends toward the inner side of the fabric treatment drum 100 to increase the spraying pressure of the water flow and / or foam; the diffusion section 503 is a second variable-diameter pipe section whose diameter gradually becomes larger along the foam flow direction and bends toward the inner side of the fabric treatment drum 100, so that the pressure of the water flow and / or foam is released after being sprayed out, forming a waterfall-like spraying effect, expanding the spraying range, and the water flow or foam acts on the clothes in the drum more evenly, thereby increasing the uniformity and effect.

[0085] Specifically, the mounting section 501 is arranged on the mounting hole of the door seal, which can ensure that the guide nozzle 500 is accurately installed and fixed on the door seal of the fabric treatment drum 100, and ensure the stability and durability of the nozzle. The diameter of the transformer section 502 gradually decreases along the direction of foam flow. This design can increase the pressure of the foam when it passes through the transformer section 502, so that the foam is sprayed into the fabric treatment drum 100 at a higher speed and energy, thereby improving the washing effect. The design of the transformer section 502 bending toward the inside of the fabric treatment drum 100 helps to control the flow direction of the foam, ensure that the foam directly enters the drum, and reduce the loss and splashing of the foam. The diameter of the diffusion section 503 gradually increases along the direction of foam flow. This design can release the pressure of the foam in the diffusion section 503, expand the spraying range of the foam, and make the foam cover the clothes in the drum more evenly. The design of the diffusion section 503 facing the inside of the fabric treatment drum 100 helps to spray the foam evenly on the clothes, and enhance the washing effect of the foam, especially for clothes in different areas of the drum.

[0086] That is, in the embodiment of the present application, through the synergistic effect of the voltage transformation section 502 and the diffusion section 503, the foam can be evenly distributed in the entire fabric treatment drum 100, thereby improving the uniformity of washing, reducing the energy loss of the foam during the flow process, and improving the energy utilization efficiency.

[0087] Further, in some possible embodiments, the detergent box includes a box body and a box cover, a detergent storage cavity is formed in the box body, and a flow channel is formed inside the box cover;

[0088] The box cover is a flat cover structure with an upper cover and a lower cover.

[0089] In the embodiment of the present application, the box cover is set to a flat structure and a flow channel for conveying detergent and / or washing water is set inside the box cover. On the one hand, such a setting will not lead to a substantial increase in the detergent box. On the other hand, by setting the flow channel inside the flat box cover, the washing water injected into the flow channel and the detergent pumped into the flow channel can have a sufficiently large pressure to flow to the side of the liquid inlet pipe 401, thereby facilitating the detergent and washing water in the flow channel to flow out, avoiding the retention of detergent and washing water in the flow channel inside the box cover, so that the washing water and washing water flowing into the mixing chamber 301 can be mixed and foamed according to a precise ratio, thereby improving the foaming effect.

[0090] Further, in some possible embodiments, the fabric treatment device has a foam washing program in which foam is introduced during washing and a normal washing program in which foam is not introduced during washing;

[0091] in

[0092] In the foam washing program of the fabric treatment device, detergent and washing water are injected into the mixed liquid chamber 301 and foamed through the foaming device 302, and the foam generated in the mixed liquid chamber 301 can enter the fabric treatment cylinder 100 through the bubble discharge pipe 402;

[0093] In a normal washing program of the fabric treatment device, washing water is separately injected into the mixing chamber 301 , and the washing water can also enter the fabric treatment drum 100 through the bubble discharge pipe 402 .

[0094] That is, in the foam washing program of the fabric treatment device in the embodiment of the present application, detergent and washing water are injected into the mixed liquid chamber 301 and foamed through the foamer 302. The generated foam can penetrate the clothing fibers more deeply and improve the washing effect, especially for stains that are difficult to clean. In the normal washing program, only washing water is injected without foaming, which reduces the use of water and detergent, helps save water and energy, and reduces the user's cost of use. At the same time, in the normal washing program, the bubble discharge pipe 402 also serves as a water inlet pipe to feed water into the fabric treatment cylinder, so there is no need to set up a separate pipeline to ensure the water inlet of the normal washing program, thereby optimizing the pipeline design.

[0095] Specifically, when the foam washing program is required, the dosing pump 700 first doses detergent into the mixing chamber 301, and then controls the opening time of the main wash water inlet valve of the main water pipeline 600 or the liquid level detection device to control the intake of a small amount of water to mix into high-concentration washing water. After the water is taken in, the inlet valve on the inlet pipe 401 and the overflow valve on the overflow pipe 800 are closed, and then air or ozone gas is introduced into the foamer 302 in the mixing chamber 301 through the external air pump 901 and / or the ozone generator 902 to foam in the mixing chamber 301. The foam enters the fabric treatment drum 100 from the door seal through the bubble discharge pipe 402 to perform foam washing on the clothes. When the foam washing program is not required, water is taken in normally. Due to the large amount of water, the water fills the mixing chamber 301 and overflows from the overflow pipe 800 and the bubble discharge pipe 402 into the fabric treatment drum 100 to wash the clothes normally. By setting the mixing chamber 301 in this way and controlling it, the water inlet switching between foam washing and normal washing can be realized, which has a dual function, and ensures the foaming amount and foaming speed without affecting the normal water inlet.

[0096] Further, in some possible embodiments, the fabric processing device further includes an overflow pipe 800 connected between the liquid mixing chamber 301 and the fabric processing cylinder 100, and an overflow valve is provided on the overflow pipe 800, and the opening and closing of the overflow pipe 800 and the fabric processing cylinder 100 can be controlled by controlling the opening and closing of the overflow valve;

[0097] In a normal washing procedure, the washing water introduced into the liquid mixing chamber 301 can enter the fabric treatment drum 100 through the bubble discharge pipe 402 and the overflow pipe 800 .

[0098] As can be seen from the above, when the fabric treatment device has an overflow pipe 800 and the device needs to use a foam washing program, the dosing pump 700 first puts detergent into the mixing chamber 301, and then controls the opening time of the main wash water inlet valve of the main water pipeline 600 or the liquid level detection device to control the inlet of a small amount of water to mix into high-concentration washing water, and after the water is in, close the inlet valve on the inlet pipe 401 and the overflow valve on the overflow pipe 800. In this way, the detergent and washing water in the mixing chamber 301 can be fully mixed and foamed.

[0099] Further, in some possible embodiments, the fabric processing device further includes an ozone generating device 900 disposed outside the mixed liquid chamber 301, the ozone generating device 900 includes an air pump 901 and an ozone generator 902 that are connected to each other, and an air inlet pipe 903 connected between the ozone generator 902 and the foaming device 302, and the air inlet pipe 903 can be used to inject ozone gas into the mixed liquid chamber 301 when the foaming device 302 foams the mixed liquid in the mixed liquid chamber 301;

[0100] A check valve 904 is also provided on the air inlet pipe 903 . The check valve 904 is designed to allow the fluid to flow from the ozone generator 902 to the liquid mixing chamber 301 and to restrict the fluid from flowing from the liquid mixing chamber 301 to the ozone generator 902 .

[0101] In the embodiment of the present application, by injecting ozone gas into the mixing chamber 301, the sterilization and deodorization effects during the washing process can be improved, because ozone is a strong oxidant that can effectively kill bacteria and decompose odors. Specifically, ozone can decompose organic stains that are difficult to remove with detergents, improve the washing quality, and make clothes cleaner. The injection of ozone gas can enhance the cleaning ability of the foam, so that the detergent in the foam can more effectively remove stains. A check valve 904 is provided on the air inlet pipe 903 to prevent ozone gas from flowing back from the mixing chamber 301 to the ozone generator 902, thereby ensuring the safe operation of the equipment and the safety of the operator. By controlling the operation of the air pump 901 and the ozone generator 902, the concentration of ozone injected into the mixing chamber 301 can be accurately controlled to achieve the best washing effect.

[0102] Further, in some possible implementations, the above-mentioned fabric processing equipment is a drum-type fabric processing equipment.
