[0046] Combination Figure 1 and Figure 2 As shown, the embodiment of the present application also provides a detergent delivery system 100, including:

[0047] A detergent box 110, for storing detergent;

[0048] a peristaltic pump 120, the peristaltic pump 120 being connected to the detergent box 110 and being used for extracting the detergent;

[0049] A first pipeline 130, wherein the first pipeline 130 is connected to the peristaltic pump 120 and is used to transport the detergent;

[0050] A pipe joint 140, wherein a first inlet end of the pipe joint 140 is connected to the first pipeline 130;

[0051] A second pipe 150, the second pipe 150 is connected to a water source and is used to transport washing water; the second pipe 150 is connected to a second inlet end of the pipe joint 140; and

[0052] The third pipeline 160 is connected to the outlet end of the pipe joint 140 and is used for conveying the mixture of the detergent and the washing water.

[0053] In the technical solution of the embodiment of the present application, when detergent needs to be added, the water flow of the washing water flows through the second pipe 150 and flows into the pipe joint 140 through the second inlet end of the pipe joint 140, and merges with the detergent extracted from the detergent box 110 by the peristaltic pump 120, and then flows into the third pipe 160 together to complete the detergent addition. Since the water does not enter the detergent box 110, there is no mixture of water and detergent remaining in the detergent box 110, which prevents bacteria from growing in the detergent box 110, which is beneficial to the health of users.

[0054] In addition, the water circuit and detergent supply circuit of the embodiment of the present application are relatively independent pipelines, which are simpler in route and lower in manufacturing cost than the double-layer detergent box 110 in the prior art. Moreover, the detergent box 110 with a drawer in the prior art often leaks because the drawer is not closed properly. In the detergent box 110 of the present application, water does not flow in the detergent box 110 and the drawer does not need to be closed, so there is no problem of detergent box 110 leaking. In addition, by adding detergent through the peristaltic pump 120, the amount of detergent can be set intelligently, thereby improving the intelligence of the washing device 10.

[0055] In the technical solution of the embodiment of the present application, the user can pre-store detergent in the detergent box 110. During the washing process, the washing control method in the washing device 10 can be:

[0056] Get the laundry job type;

[0057] Determining the amount of detergent to be used according to the type of laundry work;

[0059] Furthermore, a water inlet valve is provided on the first pipe 130; the washing control method in the washing device 10 can also be:

[0060] Determining the amount of washing water according to the type of laundry work;

[0061] The peristaltic pump 120 is controlled to pump the detergent in the amount of detergent into the pipe joint 140 , and the water inlet valve is controlled to deliver the washing water into the second pipe 150 according to the amount of washing water.

[0062] Furthermore, in the embodiment, the washing control method in the washing device 10 may also be:

[0063] Determining the time for pumping the amount of detergent according to the type of laundry operation;

[0064] According to the time, the opening degree of the water inlet valve and the rotation speed of the peristaltic pump 120 are determined.

[0065] According to the above control method, the amount of water and the amount of detergent can be accurately determined according to the type of laundry, avoiding excessive or insufficient water and / or detergent, reducing resource waste and avoiding uncleanly washed clothes. Furthermore, in the prior art, it is necessary to increase the rotation time of the washing inner drum to dissolve the washing solvent through water; while the utility model determines the opening of the water inlet valve and the rotation speed of the peristaltic pump 120 according to the time to match the water inlet speed and the detergent delivery speed, so as to facilitate the detergent to be dissolved in the water during the flow of water and detergent, and reduce the washing inner drum rotation time required to dissolve the detergent in the washing drum, which is beneficial to energy saving.

[0066] As an optional implementation of the above embodiment, Figure 2 , Figure 3 and Figure 4 As shown, the detergent box 110 has a first accommodating chamber S1 and a second accommodating chamber S2; the first accommodating chamber S1 is used to accommodate the first type of detergent, and the second accommodating chamber S2 is used for the second type of detergent. The peristaltic pump 120 includes a first peristaltic channel 121 and a second peristaltic channel 122, and the first peristaltic channel 121 connects the first accommodating chamber S1 and the first pipe 130. The detergent delivery system 100 also includes a fourth pipe 170, and the second peristaltic channel 122 connects the second accommodating chamber S2 and the fourth pipe 170; the fourth pipe 170 connects the pipe joint 140 and one of the first pipes 130. In practice, when the peristaltic pump 120 is started, the first type of detergent is pumped into the pipe joint 140 through the first peristaltic channel 121 and the first pipe 130 in sequence; the second type of detergent is pumped into the pipe joint 140 through the second peristaltic channel 122 and the fourth pipe 170 in sequence, or is transported to the pipe joint 140 after merging with the first type of detergent in the first pipe 130.

[0067] In an embodiment, the first accommodating chamber S1 and the second accommodating chamber S2 store different types of detergents respectively; for example, the first accommodating chamber S1 and the second accommodating chamber S2 store laundry detergent and softener respectively; the first accommodating chamber S1 and the second accommodating chamber S2 store laundry detergent and disinfectant respectively; the first accommodating chamber S1 and the second accommodating chamber S2 store softener and disinfectant respectively. In some embodiments, the detergent box 110 may also be provided with a fourth accommodating chamber, and the peristaltic pump 120 is configured to pump different detergents in the first accommodating chamber S1, the second accommodating chamber S2, and the fourth accommodating chamber into the pipe joint 140 for mixing, for example, the first accommodating chamber S1, the second accommodating chamber S2, and the fourth accommodating chamber store laundry detergent, softener, and disinfectant respectively.

[0068] In an embodiment, the laundry control method further includes:

[0069] Determine the dosage of the first type of detergent and the dosage of the second type of detergent according to the type of laundry;

[0070] The peristaltic pump 120 is controlled to pump the first type of detergent into the pipe joint 140 through the first peristaltic channel 121 and the second peristaltic channel 122 is controlled to pump the second type of detergent into the pipe joint 140. Therefore, in the embodiment of the present application, the ratio between different detergents can be accurately determined according to the type of laundry, thereby improving the cleanliness of the clothes and effectively protecting the clothes.

[0071] Reference Figure 3 As shown, the detergent box 110 is provided with a liquid outlet interface. An outlet groove is provided in the accommodating chamber, and the outlet groove is arranged lower than the cavity wall of the accommodating chamber. A liquid outlet hole is provided in the accommodating chamber, and the liquid outlet hole extends from the liquid outlet interface to the outlet groove and is connected with the outlet groove. The extraction column of the peristaltic pump 120 extends into the liquid outlet hole through the liquid outlet interface (sealed with it). Since the outlet groove is arranged lower than the cavity wall of the accommodating chamber, the detergent is collected near the outlet groove; under the action of the peristaltic pump 120, the detergent is sucked into the peristaltic channel of the peristaltic pump 120. With such a configuration, the extraction resistance of the peristaltic pump 120 can be reduced and the efficiency of pumping detergent can be improved.

[0072] As an optional implementation of the above embodiment, Figure 1 As shown, the detergent delivery system further includes a foamer 180, and the foamer 180 is connected to the third pipe 160. Figure 5 He Ru Figure 6 As shown, a foaming body 182 is provided in the foaming device 180, and a plurality of foaming fins 1821 are provided on the foaming body 182. In the embodiment, the mixture of water and detergent flows into the foaming device 180 through the third pipe 160; the mixture of water and detergent dissolves the detergent in advance and forms foam under the action of the foaming fins 1821, which can improve the dissolution efficiency and uniformity of the detergent, reduce the rotation time of the washing inner drum, and improve the washing efficiency and the cleanliness of the laundry.

[0073] The foam body 182 may be a closed loop structure, such as Figure 6 It can also be a non-closed ring structure, such as a C-shaped structure, a V-shaped structure, etc. When the water flow carries the detergent through the foaming body 182, it interacts with the foaming fins 1821 on the foaming body 182, thereby generating bubbles.

[0074] like Figure 5 As shown, the foamer 180 includes a housing 181, one end of which is connected to the third pipe 160. A foaming body 182 is provided in the housing 181; the foaming fins 1821 on the foaming body 182 abut against the housing 181. In some embodiments, the other end of the foamer 180 is connected to the nozzle 190, or is directly introduced into the washing housing 181 through a pipe.

[0075] In some embodiments, the foamer 180 may also be an ultrasonic foamer 180 or a plurality of foaming columns may be disposed in the foamer 180 .

[0076] As an optional implementation of the above embodiment, the foam body 182 has an extension direction; the foam body 182 has a plurality of sections 1822, the normal direction of the section 1822 is the extension direction; the normal direction of the section 1822 is set at an angle with the water flow direction; each section 1822 is provided with a plurality of foam fins 1821 arranged at intervals along the circumference of the section 1822. Figure 8 As shown, the extension direction of the foam body 182 is the tangent direction of a certain circle, and the cross section 1822 of the foam body 182 is circular; the space occupied by the cross section 1822 moving along the circumferential direction is the space occupied by the foam body 182. The normal direction of the cross section 1822 is the extension direction, which can be understood as: the normal direction of the cross section 1822 is perpendicular to the tangent direction of the circle in which the foam body 182 moves. Figure 7 and Figure 8 As shown, a plurality of foaming fins 1821 are provided at a cross section 1822 of the foaming body 182 at circumferential intervals along the cross section 1822. When water carries detergent, the foaming fins 1821 can fully disturb the water flow, causing a small relative movement between the water and the detergent to generate bubbles.

[0077] In some embodiments, the normal direction of the cross section 1822 is set at an angle to the water flow direction, thereby enhancing the disturbance intensity of the foaming fins 1821 on water and detergent and improving the solubility of the detergent. Figure 5 and Fig. 9 shown.

[0078] As an optional implementation of the above embodiment, there are multiple foaming bodies 182, and the multiple foaming bodies 182 are arranged in sequence along the water flow direction. Fig. 9 As shown, three foaming bodies 182 are provided in the foamer 180, and each foaming body 182 is provided with a plurality of foaming fins 1821; by providing a plurality of foaming bodies 182 spaced apart along the water flow direction, the detergent can be effectively dissolved and foamed.

[0079] In an embodiment, two or more foaming bodies 182 may be provided.

[0080] In the embodiment, the spacing between the foaming bodies 182 can be equidistant. The spacing between the foamers 180 can also be non-equidistant. For example, the spacing between the foaming bodies 182 gradually decreases along the water flow direction, and the foaming bodies 182 that the water flow encounters first play a role in dissolving the detergent in the water, while the foaming bodies 182 that follow mainly play a role in foaming.

[0081] As an optional implementation of the above embodiment, the liquid inlet direction of the first pipe 130 is set at an acute angle to the water flow direction. Figure 2 As shown, the angle between the liquid inlet direction of the first pipe 130 and the water flow direction is α, so that when the detergent flows out through the first pipe 130, the flow direction of the detergent has a speed in the direction of the water flow, and the water carries the detergent to flow to the third pipe 160, which can avoid the detergent staying at the pipe joint 140.

[0082] Similarly, if Figure 2 As shown, the liquid inlet direction of the fourth pipe 170 is set at an acute angle to the water flow direction. The angle between the liquid inlet direction of the fourth pipe 170 and the water flow direction is β. α and β are preferably acute angle values ​​of 75° or less, such as 20-75°.

[0083] As an optional implementation of the above embodiment, Figure 1 As shown, the detergent delivery system 100 further includes a fifth pipe and a nozzle 190. The nozzle 190 is connected to the foamer 180 through the fifth pipe; the nozzle 190 is configured to spray the mixture of the detergent and the washing water into the washing drum of the laundry device in a preset direction. The water and detergent mixture after passing through the foamer 180 is in a foamy state; the foamy water and detergent mixture is sprayed into the washing drum of the laundry device in a preset direction by the nozzle 190, so that it can evenly cover the clothes inside the inner drum, and the fully foamed washing solvent water flow can fully contact and infiltrate the clothes in the drum, so that the washing cleanliness is better.

[0084] In an embodiment, the preset direction of the nozzle 190 spray is as follows: Fig.11 , Fig.12 As shown, it is arranged to be arranged at an acute angle to the direction of gravity, approximately between 30-60°, such as 30°, 40°, 45°, 50°, 55° or 60°.

[0085] As an optional implementation of the above embodiment, Fig.10As shown, the end of the nozzle 190 away from the fifth pipe is an arc structure 191, and a plurality of spray holes 192 are arranged on the arc structure 191. The end of the nozzle 190 away from the fifth pipe is designed to be spherical, and the spray holes 192 are designed on the spherical shape, and the mixed water flow can be sprayed into the machine through the spray holes 192. Based on the spherical opening design of the nozzle 190, the sprayed mixed solvent can be sprayed to different areas of the clothes, roughly in a fan-shaped structure similar to a shower spray, and can evenly cover the clothes inside the inner drum; the fully foamed washing solvent water flow can fully contact and infiltrate the clothes in the drum, and the washing cleanliness is better.

[0086] As an alternative implementation of the above embodiment, Figure 3 As shown, the detergent box 110 is provided with a floating ring 111 and a detection structure; the detection structure is configured to generate a prompt signal when the floating ring 111 enters the detection range of the detection structure, so as to prompt the user to put detergent into the detergent box 110. In some embodiments, a first floating ring positioning column is designed inside the first accommodating chamber S1, and a first floating ring is installed on the first floating ring positioning column. The first floating ring will float as the detergent in the detergent accommodating chamber increases or decreases. The first magnetic detection mechanism is installed below the first floating ring. When the laundry detergent in the first accommodating chamber S1 decreases and falls into the detection range of the first magnetic detection mechanism as the user uses it, the first magnetic detection mechanism detects the magnetic signal and transmits it to the washing machine control system to feedback a prompt signal for adding laundry detergent. A second floating ring positioning column is designed inside the second accommodating chamber S2, and a second floating ring is installed on the second floating ring positioning column. The floating ring will float as the detergent in the detergent accommodating chamber increases or decreases. The second magnetic detection mechanism is installed below the second floating ring. When the second accommodating chamber S2 decreases and falls within the detection range of the second magnetic detection mechanism as the user uses it, the second magnetic detection mechanism detects the magnetic signal and transmits it to the washing machine control system to feedback a prompt signal for adding softener.
