For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0041] The existing detergent delivery method of washing machines is to put detergent into a detergent delivery box, use tap water to flush the detergent stored in the detergent delivery box directly to the bottom of the washing drum, and then rely on the rotation and stirring of the inner drum to dissolve the detergent and slowly generate foam. However, this detergent delivery method has the following defects: it takes time for the detergent to dissolve at the bottom of the drum and it also takes time to form foam, which will prolong the washing time; in addition, due to the limitation of the bottom structure of the washing machine drum, part of the high-concentration washing solution remains in the drainage pipe of the drainage outlet at the bottom of the drum and cannot fully contact with the clothes, which wastes part of the detergent to a certain extent and greatly affects the detergent from playing its due role.

[0042] Therefore, in order to solve the above technical problems, the present application proposes a washing machine 100.

[0043] For ease of description and understanding, the direction of the washing machine 100 facing the user is referred to as the front direction, and the direction facing away from the user is referred to as the rear direction.

[0044] See also Figure 1 As shown, Figure 1A structural schematic diagram of a washing machine 100 of the present application is shown, wherein the washing machine 100 includes a housing 110 , a tub 120 , a drum, a door 130 and a detergent delivery system 140 .

[0045] It should be understood that the washing machine 100 shown in the present embodiment is a drum washing machine 100 , and in other embodiments, the washing machine 100 may also be other types of washing machines 100 , such as a pulsator washing machine 100 .

[0046] The housing 110 may be the overall external structure of the washing machine 100. The housing 110 is a hollow structure in which other component structures of the washing machine 100 may be arranged, such as a circuit structure, an air duct structure, a drive structure, and a drainage structure. The housing 110 may be in the shape of a hollow rectangular parallelepiped or a hollow cylindrical shape, and is not limited to the above shapes. The housing 110 has an input hole formed on the front surface of the housing 110.

[0047] The tub 120 is disposed in the housing 110, and the tub 120 may be disposed in a hollow cylindrical shape or in other shapes. The tub 120 has an inlet hole formed in the front surface of the tub 120. The drum is disposed in the tub 120 and rotatably disposed in the tub 120 for washing clothes. The drum has a washing cavity, and an inlet is disposed at the front side of the drum. Clothes are put into the washing cavity through the input hole, the inlet hole and the inlet for washing.

[0048] See also Figure 1 As shown, the door body 130 is arranged on the front side of the shell 110 to close the input hole. The door body 130 can be hinged to the front side of the shell 110, and the input hole can be opened or closed by rotating around the hinge point. Opening the door body 130 makes it convenient to put clothes from the input hole and take clothes out of the washing chamber. After closing the door body 130, the shell 110 is a sealed structure, and the washing machine 100 will start. In order to facilitate observation of the operation status, a transparent window can be set on the door body 130 corresponding to the input hole. In addition, in order to prevent the liquid in the washing chamber from overflowing, the door body 130 is also provided with a door sealing ring 131 to seal the above-mentioned input hole and inlet hole to ensure that the washing chamber is in a closed environment during the washing process.

[0049] It can be understood that the door sealing ring 131 is an annular structure, and a pleated structure is formed inside the door sealing ring 131 to form a sealing structure with the inner side of the door body 130 .

[0050] The detergent dispensing system 140 is disposed in the housing 110 and located at the top of the housing 110 . The detergent dispensing system 140 includes a distribution box 141 , a detergent dispensing module and a water inlet module 143 .

[0051] See also Figure 1 and Figure 2As shown, the detergent dispensing module includes a detergent storage portion 1420 and a detergent delivery device 1421 .

[0052] The detergent storage part 1420 is a hollow structure to form a receiving cavity, and an opening may be provided at the upper part thereof, through which detergent can be added into the receiving cavity to replenish the detergent in the receiving cavity. A placement cavity may be provided at the front side of the housing 110, and the detergent storage part 1420 may be detachably arranged in the placement cavity, so that the detergent storage part 1420 can be removed to replenish the detergent; wherein, the detergent storage part 1420 may be removed from the placement cavity by sliding or pulling.

[0053] The detergent delivery device 1421 is connected to the detergent storage portion 1420. The detergent delivery device 1421 can discharge the detergent stored in the accommodating cavity into the distribution box 141, so that the detergent and the tap water in the water inlet module 143 are mixed in the distribution box 141; the detergent delivery device 1421 can adopt a pumping device, such as a pump, a fan and other structures.

[0054] See also Figure 2 and Figure 3 As shown, Figure 2 It shows a schematic diagram of the connection structure between the water inlet module 143 and the distribution box 141 provided by the present application, Figure 3 The schematic diagram of the structure of the first water inlet pipe 1430 provided by the present application connected to the distribution box 141 is shown. The water inlet module 143 includes a first water inlet pipe 1430, a second water inlet pipe 1431, a first water inlet valve 1432 and a second water inlet valve 1433. The first water inlet pipe 1430 and the second water inlet pipe 1431 are both connected to the distribution box 141 to introduce tap water into the distribution box 141. In addition, the first water inlet valve 1432 is arranged on the first water inlet pipe 1430, and the second water inlet valve 1433 is arranged on the second water inlet pipe 1431, so as to adjust the water flow in the first water inlet pipe 1430 and the second water inlet pipe 1431 by adjusting the opening of the first water inlet valve 1432 / the second water inlet valve 1433.

[0055] It is understandable that one end of the first water inlet pipe 1430 and the second water inlet pipe 1431 are connected to the distribution box 141 , and the other end is connected to the water supply pipe, so as to input tap water into the distribution box 141 .

[0056] In addition, the first water inlet pipe 1430 and the second water inlet pipe 1431 can adopt an independent main pipe, that is, the first water inlet pipe 1430 and the second water inlet pipe 1431 do not affect each other. The first water inlet pipe 1430 and the second water inlet pipe 1431 can also adopt an independent main pipe, that is, the first water inlet pipe 1430 and the second water inlet pipe 1431 are both branches, and the opening of the first water inlet valve 1432 and the second water inlet valve 1433 is used to adjust whether the tap water in the main pipe enters the first water inlet pipe 1430, the second water inlet pipe 1431, or enters the first water inlet pipe 1430 and the second water inlet pipe 1431 at the same time.

[0057] In some embodiments, when the first water inlet pipe 1430 and the second water inlet pipe 1431 share the same water inlet main pipe, the first water inlet valve 1432 and the second water inlet valve 1433 may also share the same water inlet valve, that is, the water inlet valve is arranged on the water inlet main pipe, and the water flow rate flowing from the water inlet main pipe into the first water inlet pipe 1430 and the second water inlet pipe 1431 is adjusted by adjusting the opening of the water inlet valve.

[0058] For further information, see Figure 4 and Figure 5 As shown, Figure 4 A schematic diagram of the top view of the interior of the distribution box 141 provided in the present application is shown; Figure 5 The schematic diagram of the three-dimensional structure of the interior of the distribution box 141 provided by the present application is shown. The distribution box 141 is provided with an air inlet 1410, a water inlet 1411, a detergent inlet 1412, a mixing channel 1413 and a mixed liquid outlet 1414. The distribution box 141 can be a square structure or a rectangular structure, but is not limited thereto, and can also be a circular, diamond, elliptical or other structure.

[0059] See also Figure 3 and Figure 4 As shown, the water inlet 1411 of the distribution box 141 is connected to the first water inlet pipe 1430 to receive the tap water in the first water inlet pipe 1430; the detergent inlet 1412 is connected to the detergent delivery device 1421 to receive the detergent in the accommodating chamber. The mixing channel 1413 includes a mixing main pipe, a water inlet branch pipe and a detergent branch pipe. The water inlet branch pipe is connected to the mixing main pipe after merging with the detergent branch pipe. The water inlet branch pipe is connected to the water inlet 1411, and the detergent branch pipe is connected to the detergent inlet 1412. That is, the tap water entering the water inlet 1411 and the detergent entering the detergent inlet 1412 are mixed and dissolved in the mixing main pipe to form a mixed solution.

[0060] In order to facilitate the production of rich and large amounts of soft foam in the distribution box 141, an air intake portion is provided in the mixing channel 1413. The air intake portion is arranged at the mixing main pipe, and the air intake portion is connected to the air intake hole 1410. The air intake hole 1410 is connected to the external environment of the distribution box 141, so that the air intake portion can be connected to the external environment through the air intake hole 1410. Air can enter the air intake portion through the air intake hole 1410, so that the air is mixed with the mixed solution inside the mixing main pipe, so that the mixed solution produces a large amount of soft foam, and the mixed solution carrying the foam is sprayed into the washing chamber of the drum through the mixed liquid outlet 1414, so as to realize the input of detergent.

[0061] By generating abundant and large amounts of soft foam in the distribution box 141, the time for the detergent to dissolve in the washing chamber can be reduced, and the washing efficiency can be improved. In addition, the problem of detergent waste caused by the inability to completely dissolve the detergent can be avoided, and the cleaning efficiency and washing efficiency can be greatly improved.

[0062] For further information, see Figure 4 and Figure 5 As shown, the air inlet includes a contraction section 1415 and a diffusion section 1416 arranged in sequence in the flow direction of the mixed solution, and the contraction section 1415 and the diffusion section 1416 are connected to each other. In the flow direction of the mixed solution, the aperture of the contraction section 1415 gradually decreases, and the aperture of the diffusion section 1416 gradually increases, that is, the aperture at the connection between the contraction section 1415 and the diffusion section 1416 is the smallest, and the air inlet is a "waisted" structure as a whole. When the mixed solution flows through the contraction section 1415, according to the Venturi effect, the mixed solution will accelerate at the air inlet, and the pressure will decrease at the diffusion section 1416 to form a vacuum zone. When the outside air flows into the air inlet through the air inlet hole 1410, the inhaled air and the detergent components in the mixed solution work together to generate a large amount of soft foam in the washing solution, and the washing solution carrying the foam is sprayed into the washing cavity in the drum through the mixed solution outlet 1414, so as to complete the delivery of the washing solution.

[0063] Understandably, see Figure 5 As shown, an air inlet 1417 is provided at the diffusion section 1416, and the distribution box 141 includes an air inlet channel 1418. The air inlet channel 1418 is connected to the outer wall of the mixing channel 1413, and the above-mentioned air inlet hole 1410 is provided on the inner bottom wall of the air inlet channel 1418. The air inlet channel 1418 is connected to the outside through the air inlet hole 1410, and the air inlet channel 1418 is connected to the air inlet part through the air inlet 1417.

[0064] In addition, when the mixed solution flows into the diffusion section 1416, the pressure of the mixed solution decreases in the diffusion section 1416 to form a vacuum area. The diffusion section 1416 can suck the air in the air intake channel 1418 into the mixed solution, thereby allowing the air to enter the air intake part more conveniently and quickly, thereby generating a large amount of rich foam in the mixing channel 1413.

[0065] In order to meet the amount of air entering, this air intake channel 1418 includes an expansion section, which is interconnected with the outer wall of the mixing channel 1413, and in the air intake direction, the aperture of this expansion section gradually increases, so that a huge amount of air enters the diffusion section 1416, reacting with the detergent components in the mixed solution to produce a large amount of soft foam.

[0066] The detergent dispensing system 140 further includes a housing, and the dispensing box 141 is disposed in the housing. Figure 4 and Figure 5 As shown, in order to prevent the mixed solution from overflowing and the mixed solution from remaining in the shell, the distribution box 141 also includes a flushing module, which includes a flushing inlet 1419, a flushing channel 14110 and a flushing outlet 14111. The flushing inlet 1419 and the flushing outlet 14111 are respectively provided at opposite ends of the flushing channel 14110, and the flushing channel 14110 is connected to the second water inlet pipe 1431 through the flushing inlet 1419, and the flushing outlet 14111 is connected to the shell.

[0067] It should be understood that the second water inlet pipe 1431 transports tap water to the flushing inlet 1419, then enters the flushing channel 14110, and finally flows into the shell through the flushing outlet 14111 to clean and discharge the residual mixed solution in the shell. The residual mixed solution flows into the washing chamber of the drum after flushing and discharge, so as to avoid waste of detergent and improve the utilization rate of detergent.

[0068] In addition, the end of the flushing channel 14110 close to the flushing outlet 14111 is connected to the outer wall of the air inlet channel 1418 to reduce the space occupied by the distribution box 141 and improve the space utilization of the outer shell 110 of the washing machine 100.

[0069] The distribution box 141 is provided with at least one flushing outlet 14111 .

[0070] For example, see Figure 4 and Figure 5 As shown, six flushing outlets 14111 are provided at the end of the flushing channel 14110, and the six flushing outlets 14111 are arranged in two rows and three columns, and the spacing between adjacent flushing outlets 14111 in the same row is equal. The multiple flushing outlets 14111 can ensure that the residual mixed solution in the housing is flushed away, avoiding the waste of detergent and improving the utilization rate of the detergent.

[0071] In the embodiment of the present application, the air inlet hole 1410 is arranged on the side of the air inlet channel 1418 close to the flushing channel 14110 to prevent the mixed solution in the mixing channel 1413 from being blocked and unable to inhale air normally. The mixed solution can overflow from the air inlet port 1417, and then flow out of the shell through the air inlet hole 1410 along the air inlet channel 1418, and the mixed solution is flushed by the tap water flowing out of the flushing outlet 14111 to prevent the mixed solution from remaining in the shell.

[0072] See also Figure 1 As shown, in order to realize that the detergent foam generated in the mixing channel 1413 can be sprayed into the washing chamber of the drum, the washing machine 100 also includes a nozzle 150, which can be arranged at the door sealing ring 131, or at the barrel 120 opening of the barrel 120, or at other positions, which are not specifically limited here. The nozzle 150 can be oriented obliquely toward the inside of the washing chamber, and the nozzle 150 is connected to the mixed liquid outlet 1414 through the spray pipe, so that the detergent with a large amount of foam generated in the mixing channel can be sprayed into the washing chamber through the spray pipe and the nozzle 150, so as to clean the clothes in the washing chamber, increase the dissolution time of the detergent, and improve the washing efficiency.

[0073] The method of adding detergent in the washing machine 100 is:

[0074] The detergent delivery device 1421 draws detergent from the detergent storage part 1420, and delivers the detergent to the mixing channel 1413 through the detergent inlet 1412. The first water inlet valve 1432 is opened, and the tap water in the first water inlet pipe 1430 enters the mixing channel 1413 through the water inlet 1411. In the mixing channel 1413, the detergent and the tap water are mixed and dissolved to form a washing mixed solution. The mixed solution moves along the mixing channel 1413. When the mixed solution flows through the contraction section 1415, according to the Venturi effect, the mixed solution in the contraction section The flow rate at 1415 is accelerated, and the pressure at the diffusion section 1416 is reduced to form a vacuum area. The outside air enters the diffusion section 1416 through the air inlet hole 1410, the air inlet channel 1418 and the air inlet port 1417. The inhaled air is mixed with the mixed solution in the diffusion section 1416. The inhaled air and the detergent components in the mixed solution act together to produce a large amount of soft foam in the mixing channel 1413. The mixed solution carrying the foam enters the spray pipe through the mixed solution outlet 1414, and is finally sprayed into the washing chamber of the drum through the nozzle 150.

[0075] Through this method of adding detergent, the detergent can be quickly dissolved and a large amount of washing solution with rich and soft foam can be produced. The washing solution can be directly added to the clothes, ensuring the utilization rate of the detergent and improving the washing efficiency.

[0076] In addition, in order to prevent the mixed solution from remaining in the shell, the second water inlet valve 1433 is opened, and the tap water in the second water inlet pipe 1431 enters the flushing channel 14110 through the flushing inlet 1419, flows into the shell through the flushing outlet 14111, flushes the inside of the shell, and then returns the flushing solution to the washing chamber of the drum, thereby improving the utilization rate of the detergent.
