[0052] In the prior art, different detergents are added into a drawer box, and the drawer box is flushed by water flow, and the different detergents are flushed into the washing tub along with the water flow; however, in this way, the water flow simply serves the purpose of carrying the different detergents into the washing tub. The mixing of the detergents requires the washing tub to be fully rotated before the different detergents can be flushed and mixed, and the mixing efficiency of different detergents is low.

[0053] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the embodiment of the present application provides a detergent mixing and dispensing device 100, comprising:

[0054] The detergent box 110 has a first receiving chamber S1 and a second receiving chamber S2 separated from each other; the first receiving chamber S1 is used to receive a first type of detergent; the second receiving chamber S2 is used to receive a second type of detergent;

[0055] a first venturi tube 120, wherein the first venturi tube 120 is connected to the detergent box 110 and communicates with the first accommodating chamber S1;

[0056] a second venturi tube 130, wherein the second venturi tube 130 is connected to the detergent box 110 and communicates with the second accommodating chamber S2;

[0057] A first water inlet pipe 141, wherein the first water inlet pipe 141 is used to connect to an external water source, and the first venturi tube 120 is connected to the first water inlet pipe 141;

[0058] a second water inlet pipe 142, wherein the second water inlet pipe 142 is used to connect to an external water source, and the second venturi tube 130 is connected to the second water inlet pipe 142;

[0059] The first drain pipe 151, the second water inlet pipe 142 is used to connect the first venturi tube 120, and is used to transport water and the first type of detergent;

[0060] A second drain pipe 152, the second drain pipe 152 is used to connect the second venturi tube 130, and is used to transport water and a second type of detergent; and

[0061] The foamer 160, the first drain pipe 151 and the second drain pipe 152 are connected to the foamer 160, and are used to mix water, the first type of detergent and the second type of detergent.

[0062] In the technical solution of the embodiment of the present application, when the washing water enters the first water inlet pipe 141, the washing water absorbs the first type of detergent in the first accommodating chamber S1 into the first venturi tube 120 when passing through the first venturi tube 120, and then the washing water and the first type of detergent are transported to the foamer 160 through the first drain pipe 151; similarly, when the washing water enters the second water inlet pipe 142, the washing water absorbs the second type of detergent in the second accommodating chamber S2 into the second venturi tube 130 when passing through the second venturi tube 130, and then the washing water and the second type of detergent are transported to the foamer 160 through the second drain pipe 152; the washing water, the first type of detergent and the second type of detergent are mixed in the foamer 160 to complete the mixed delivery of the first type of detergent and the second type of detergent. Compared with the prior art, in the technical solution of the present application, after different detergents are mixed with water flow by using the Venturi principle, the different detergents are foamed and mixed in the foamer 160 before delivery, thereby improving the mixing efficiency of different detergents.

[0063] In addition, the water circuit and detergent liquid supply circuit of the embodiment of the present application are relatively independent pipelines. Compared with the drawer box setting in the prior art, the route is simple and the manufacturing cost is low. Moreover, in the prior art, there is also the problem that the detergent box 110 with a drawer often leaks because the drawer is not closed properly. In the present application, water does not flow in the detergent box 110 and there is no need to close the drawer, so there is no problem of water leakage in the detergent box 110.

[0064] In the 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 can also be provided with a third accommodating chamber, in which the third water inlet pipe, the third venturi tube and the third drain pipe are configured, and the structure thereof refers to the first accommodating chamber S1, the first water inlet pipe 141, the first venturi tube 120 and the first drain pipe 151. For example, the first accommodating chamber S1, the second accommodating chamber S2 and the fourth accommodating chamber store laundry detergent, softener and disinfectant respectively.

[0065] In the embodiment, the foamer 160 may be an ultrasonic foamer 160 or a foamer 160 with fins or a plurality of foaming columns. For example, dense vertical columns are designed inside the foamer 160, and when the mixed water flows through the dense vertical columns, vortices or microbubbles are generated to achieve a good dissolving and foaming effect, so that the washing solvent is dissolved more fully and mixed.

[0066] In the following embodiments, the first accommodating chamber S1 stores laundry detergent, and the second accommodating chamber S2 stores softener.

[0067] As an optional implementation of the above embodiment, Figure 4 , Figure 5 As shown, the first venturi tube 120 includes a first liquid receiving pipe section 121, which is connected to the detergent box 110; the first liquid receiving pipe section 121 includes a first throat 1212 and a first throat pipe 1211 connected to each other; the first throat 1212 is connected to the first water inlet pipe 141 and the first drain pipe 151; the first throat pipe 1211 is connected to the first accommodating chamber S1 and the first throat 1212. Figure 5 and Figure 6As shown, the second venturi tube 130 includes a second liquid receiving pipe section (its structure refers to the first venturi tube), and the second liquid receiving pipe section is connected to the detergent box 110; the second venturi tube 130 includes a second throat and a second throat pipe connected to each other; the second throat is connected to the second water inlet pipe 142 and the second drain pipe 152; the second throat pipe connects the second accommodating chamber S2 and the second throat.

[0068] In an embodiment, Figure 2 As shown, the outer periphery of the (first and second) liquid receiving pipe sections is provided with a protrusion, and the protrusion is provided with a first fixing hole. The detergent box 110 is correspondingly provided with a second fixing hole, and the (first and second) first liquid receiving pipe sections 121 are fixed to the washing box by screws. When the water flows into the first throat 1212, the first type of detergent in the first accommodating chamber S1 is sucked into the first throat 1212 through the first throat pipe 1211 based on the negative pressure, mixed with the water flow, and then flows into the first drain pipe 151. When the water flows into the second throat, the second type of detergent in the second accommodating chamber S2 is sucked into the second throat through the second throat pipe based on the negative pressure, mixed with the water flow, and then flows into the second drain pipe 152.

[0069] As an optional implementation of the above embodiment, Figure 5 As shown, the diameter of the first throat pipe 1211 gradually decreases in the direction away from the detergent box 110; the diameter of the second throat pipe gradually decreases in the direction away from the detergent box 110. In the embodiment, the first throat pipe 1211 and the second throat pipe are trumpet-shaped structures, so that when water flows through the first throat 1212 and the second throat, strong suction is generated to suck the first type of detergent and the second type of detergent into the corresponding first throat 1212 and the second throat.

[0070] As an optional implementation of the above embodiment, Figure 5 As shown, the first venturi tube 120 also includes a first inlet pipe section 122 and a first inlet pipe section 122; the first inlet pipe section 122 is connected to the first water inlet pipe 141, and the first outlet pipe section 123 is connected to the first drain pipe 151; the two ends of the first throat 1212 are respectively connected to the first inlet pipe section 122 and the first inlet pipe section 122; wherein the pipe diameter of the first throat 1212 is smaller than the pipe diameters of the first inlet pipe section 122 and the first outlet pipe section 123; the second venturi tube also includes a second inlet pipe section and a second outlet pipe section; the second inlet pipe section is connected to the second water inlet pipe 142, and the second outlet pipe section is connected to the second drain pipe 152; the two ends of the second throat are respectively connected to the second inlet pipe section and the second outlet pipe section; wherein the pipe diameter of the second throat is smaller than the pipe diameter of the second inlet pipe section and the second outlet pipe section.

[0071] In an embodiment, when water flows through the first throat 1212 (or the second throat), a negative pressure area is formed at the first throat 1211 (or the second throat) due to the reduction in the cross-sectional area, thereby generating suction to suck the first and second types of detergents into the corresponding first throats 1212 and second throats.

[0072] In the embodiment, the first inlet pipe section 122, the first liquid receiving pipe section 121 and the first outlet pipe section 123 are made as one piece. The first inlet pipe section 122 and the first water inlet pipe 141 can be connected by a flange or by a threaded connection (with a sealing ring); the first outlet pipe section 123 and the first drain pipe 151 can be connected by a flange or by a threaded connection (with a sealing ring). The second inlet pipe section, the second liquid receiving pipe section and the second outlet pipe section are made as one piece. The second inlet pipe section and the second water inlet pipe 142 can be connected by a flange or by a threaded connection (with a sealing ring); the second outlet pipe section and the second drain pipe 152 can be connected by a flange or by a threaded connection (with a sealing ring).

[0073] As an optional implementation of the above embodiment, Figure 5 As shown, the detergent box 110 includes a first liquid outlet interface S11 and a second liquid outlet interface (not shown in the example, its structure refers to the first liquid outlet interface S11); the first liquid outlet interface S11 is connected to the first accommodating chamber S1, and the second liquid outlet interface is connected to the second accommodating chamber S2; the first venturi tube 120 is connected to the first liquid outlet interface S11, and the second venturi tube 130 is connected to the second liquid outlet interface; wherein, the first liquid outlet interface S11 and the second liquid outlet interface are arranged at the bottom of the detergent box 110.

[0074] As an optional implementation of the above embodiment, Figure 5 As shown, the (first and second) liquid receiving pipe sections are provided with a first fixing hole, and the detergent box 110 is provided with a second fixing hole; the first fixing hole and the second fixing hole are connected by a connecting piece. In an embodiment, a protrusion is provided on the outer periphery of the (first and second) liquid receiving pipe sections, and a first fixing hole is provided on the protrusion. The detergent box 110 is provided with a first liquid outlet interface S11 and a second liquid outlet interface. A second fixing hole is provided near the first liquid outlet interface S11 and the second liquid outlet interface. The first fixing hole and the second fixing hole are connected by a connecting piece, and the (first and second) liquid receiving pipe sections are respectively connected to the (first and second) liquid outlet interfaces (a sealing ring is provided between the two). In an embodiment, the first fixing hole and the connecting piece, and the second fixing hole and the connecting piece are threadedly matched.

[0075] As an optional implementation of the above embodiment, Figure 7As shown, the foamer 160 includes a shell 161, and the shell 161 is provided with a first liquid inlet interface 1611 and a second liquid inlet interface 1612. The first liquid inlet interface 1611 is communicated with the first drain pipe 151; the second liquid inlet interface 1612 is communicated with the second drain pipe 152. The shell 161 is rotatably provided with a first countercurrent flap 162 and a second countercurrent flap 163; the first countercurrent flap 162 is configured to open the first liquid inlet interface 1611 based on the water pressure of the water flow when there is water flow, and to close the first liquid inlet interface 1611 based on gravity when there is no water flow; the second countercurrent flap 163 is configured to open the second liquid inlet interface 1612 based on the water pressure of the water flow when there is water flow, and to close the second liquid inlet interface 1612 based on gravity when there is no water flow. In the embodiment, the first countercurrent flap 162 is flipped open under the impact of the mixed water flow, and the mixed water flow can pass smoothly. When the mixed water flow stops, the first backflow flap 162 is closed under gravity to seal and prevent the mixed mixture from flowing back. Similarly, the second backflow flap 163 is flipped open under the impact of the mixed water flow, and the mixed water flow can pass smoothly. When the mixed water flow stops, the second backflow flap 163 is closed under gravity to seal and prevent the mixed mixture from flowing back.

[0076] In order to prevent the problem that the counterflow flap is turned up to a high place and cannot fall down, a limiting rib is set on the shell 161. The limiting rib can effectively prevent the upward opening and closing angle of the counterflow flap from exceeding a preset angle, so as to ensure that the counterflow flap can fall smoothly in the absence of mixed water flow. Specifically, the preset angle can be 90°, or a value lower than 90°. For example, the limiting rib is extended horizontally, and at this time, the counterflow flap can be limited to rotate to a horizontal position at most, that is, the counterflow flap rotates between a vertical position and a horizontal position.

[0077] Specifically, if Figure 8 As shown, the housing 161 is provided with a first limiting rib 164 and a second limiting rib 165. When the first countercurrent flap 162 opens the first liquid inlet interface 1611, the first limiting rib 164 is used to abut against the first countercurrent flap 162 after the first countercurrent flap 162 rotates a preset angle. When the second countercurrent flap 163 opens the second liquid inlet interface 1612, the second limiting rib 165 is used to abut against the second countercurrent flap 163 after the second countercurrent flap 163 rotates a preset angle.

[0078] As an optional implementation of the above embodiment, Figure 1 and Fig. 9As shown, the detergent mixing and dispensing device 100 further includes a nozzle 180 and a drain pipe 170, and the foamer 160 is connected to the nozzle 180 through the drain pipe 170. The nozzle 180 is configured to dispense the mixed detergent into the washing drum in a preset direction. The foamy water and detergent mixture is sprayed into the washing drum of the laundry device in a preset direction through the nozzle 180, so that it can evenly cover the clothes inside the inner drum, and the fully foamed washing solvent water flow can fully contact and soak the clothes in the drum, so that the washing cleanliness is better.

[0079] In an embodiment, the preset direction of the nozzle 180 is as follows: Fig. 9 As shown, it is arranged to be arranged at an acute angle α to the direction of gravity, approximately between 30-60°, such as 30°, 40°, 45°, 50°, 55° or 60°.

[0080] As an optional implementation of the above embodiment, Fig. 9 As shown, the nozzle 180 has an injection channel 181 and a spray hole 182, and the spray hole 182 is connected to the injection channel 181. A foaming net 183 is arranged in the injection channel 181. The foaming net 183 is a porous plate structure, and the porous foaming net 183 can further promote the full dissolution and foaming of the washing solvent, and improve the mixing degree of the detergent. The aperture of the spray hole 182 gradually increases along the direction of the water flow; that is, the opening area of ​​the outlet end of the nozzle 180 is larger than the area inside it, and the area is gradually increasing. When the water flows through the spray hole 182, a trumpet-shaped spraying effect will be formed. The spraying area can effectively cover the clothes in the drum, and it can ensure that the washing solvent mixture is evenly and effectively sprayed on all the clothes, so as to achieve full mixing and infiltration of the detergent and the clothes, which not only improves the cleanliness of the clothes washing, but also indirectly saves electric energy.
