Figure 3 It is a structural schematic diagram of an embodiment of a single water inlet pipe of a washing machine of the utility model. Figure 4 yes Figure 2 Schematic diagram of the structure of the first mixing device shown in .

[0038] See also Figures 1 to 4 The present application provides a washing machine, which may include: a housing 10, a detergent storage box 200, a first mixing device 300 and a second mixing device 400. A washing tub 120 is arranged in the housing 10. The detergent storage box 200 is arranged in the housing 10, and detergent is placed in the detergent storage box 200. The first mixing device 300 is arranged in the housing 10, and the first mixing device 300 includes a mixing channel 310 and a flushing channel 320. The input end of the mixing channel 310 is connected to the detergent storage box 200, and the detergent in the detergent storage box 200 can enter the mixing channel 310. The output end of the mixing channel 310 is connected to the washing tub 120. The input end of the flushing channel 320 is used to connect to an external water source, and the output end of the flushing channel 320 is connected to the mixing channel 310. The flushing channel 320 can flush water into the mixing channel 310 to form a mixed liquid after mixing with the detergent. The second mixing device 400 is disposed in the housing and is connected to the output end of the mixing channel 310 and the washing tub 120 , so that gas can be introduced into the second mixing device 400 , so that the gas and the mixed liquid are mixed and then output into the washing tub 120 .

[0039] When the washing machine is in use, the articles are placed into the rolling drum through the opening and the loading port, and the door body is closed on the housing 10 so that the door body and the door sealing ring 130 are sealed against each other. The detergent in the detergent storage box 200 is input into the mixing channel 310, and the external water is flushed into the mixing channel 310 through the flushing channel 320 so that the water and the detergent are mixed to form a mixed liquid. The mixed liquid enters the second mixing device 400 through the output end of the mixing channel 310.

[0040] After the mixed liquid enters the second mixing device 400, the second mixing device 400 introduces gas into the mixed liquid to mix the gas with the mixed liquid, thereby forming washing water and generating foam. After that, the washing water and foam are input into the washing tub 120. The detergent in the washing machine passes through the first mixing device 300 and the second mixing device 400 in sequence to be fully mixed and dissolved, thereby effectively improving the efficiency of foam formation, and preventing part of the detergent from remaining at the bottom water outlet of the washing tub 120, thereby improving the utilization efficiency of the detergent and preventing the waste of the detergent.

[0041] See also Figures 1 to 3 The housing 10 is used to protect the components therein. The housing 10 may include a main water inlet pipe 500, one end of which is used to communicate with an external water source, and the other end of which is connected to the washing tub 120, so that external water can be input into the washing tub 120. The washing machine can input water into the washing tub 120 through the main water inlet pipe 500, and can also input water into the washing tub 120 through the first mixing device 300 and the second mixing device 400.

[0042] In the present embodiment, the detergent storage box 200 is accommodated in the housing 10 , and the detergent storage box 200 is located at the upper side of the washing tub 120 , so as to facilitate the input of detergent into the washing tub 120 .

[0043] Figure 5 yes Figure 4 A schematic structural diagram of the structure shown from another perspective. Figure 6 yes Figure 3 A schematic structural diagram of the first mixing device of the structure described in FIG.

[0044] See also Figures 1 to 6 In this embodiment, the first mixing device 300 is accommodated in the housing 10. The first mixing device 300 is disposed on the peripheral side of the detergent storage box 200 so that the detergent enters the first mixing device 300 from the detergent storage box 200. In some embodiments, the first mixing device 300 is located on the upper side of the detergent storage box 200.

[0045] See also Figure 2 and Figure 3 In this embodiment, a delivery device 210 is provided between the first mixing device 300 and the detergent storage box 200 to input detergent from the detergent storage box 200 into the mixing channel 310. In some embodiments, the delivery device 210 can be a delivery pump or a delivery valve.

[0046] See also Figures 4 to 6In this embodiment, the first mixing device 300 may include a mixing channel 310 and a flushing channel 320. The input end of the mixing channel 310 is connected to the detergent storage box 200 through the conveying device 210, so that the detergent in the detergent storage box 200 can be input into the mixing channel 310 through the conveying device 210.

[0047] The mixing channel 310 is used to mix water and detergent into a mixed liquid to improve the efficiency of subsequent detergent dissolution and foam generation. The output end of the mixing channel 310 is connected to the second mixing device 400 so that the mixed liquid can be input into the second mixing device 400 for further dissolution of the detergent.

[0048] The input end of the flushing channel 320 is used to connect to external water, and the output end of the flushing channel 320 is connected to the mixing channel 310, so that external water can rush into the mixing channel 310 through the flushing channel 320. After the water rushes into the mixing channel 310, the kinetic energy of the water can hit the inner wall of the mixing channel 310 to mix the water and the detergent.

[0049] In some embodiments, a detergent inlet 311 is provided at the input end of the mixing channel 310 , and the detergent inlet 311 is connected to the conveying device 210 , so that the detergent in the detergent storage box 200 can enter the input end of the mixing channel 310 through the conveying device 210 and the detergent inlet 311 .

[0050] The detergent inlet 311 is located at the intersection of the mixing channel 310 and the flushing channel 320, so that after the water in the flushing channel 320 is input into the mixing channel 310, the water can be directly flushed onto the detergent, thereby facilitating the full mixing of water and detergent, thereby improving the dissolution efficiency of the detergent.

[0051] In some embodiments, in a plane perpendicular to the axis of the detergent inlet 311, the aperture of the detergent inlet 311 is smaller than the width of the mixing channel 310. After the detergent is squeezed into the mixing channel 310 through the detergent inlet 311, the radius of the detergent output from the detergent inlet 311 is small, so as to prevent a large amount of detergent from being output in a short time, prevent the detergent from sticking, and facilitate the mixing of the detergent and water, thereby improving the dissolution efficiency of the detergent.

[0052] In other embodiments, a mixed liquid outlet 312 is provided at the output end of the mixing channel 310. In a plane perpendicular to the axis of the mixed liquid outlet 312, the aperture of the mixed liquid outlet 312 is smaller than the width of the mixing channel 310, so that the mixed liquid can be output to the second mixing device 400 through the mixed liquid outlet 312. In the process of the mixed liquid passing through the mixed liquid outlet 312 from the mixing channel 310, the mixed liquid is squeezed to further dissolve the detergent in the water, thereby improving the dissolution efficiency of the detergent.

[0053] In some embodiments, the output end of the mixing channel 310 is bent. When the mixed liquid moves toward the output end of the mixing channel 310, the mixed liquid can impact and collide with the inner peripheral wall of the bent mixing channel 310, thereby further improving the dissolution efficiency of the detergent.

[0054] In other embodiments, the angle between the output end of the mixing channel 310 and the input end of the mixing channel 310 is a right angle. During the flow of the mixed liquid along the mixing channel 310, it can impact the inner peripheral wall of the output end of the mixing channel 310 and then be input into the second mixing device 400.

[0055] In other embodiments, the output end of the mixing channel 310 is arranged to be curved and meandering, so that the mixed liquid can collide and impact with the inner wall of the mixing channel 310 for multiple times, thereby improving the dissolution efficiency of the detergent and water.

[0056] In other embodiments, the mixing channel 310 is disposed in a curved and meandering shape as a whole.

[0057] In some embodiments, the mixing channel 310 is tilted downward in a direction from the input end of the mixing channel 310 toward the output end of the mixing channel 310 , so as to effectively prevent the mixed liquid from remaining in the mixing channel 310 .

[0058] In other embodiments, the flushing channel 320 is tilted downward in a direction from the input end of the flushing channel 320 toward the output end of the flushing channel 320 to prevent water or mixed liquid from remaining in the flushing channel 320 .

[0059] See also Figures 4 to 6 In this embodiment, there is an angle between the output end of the flushing channel 320 and the input end of the mixing channel 310, so that the water output from the flushing channel 320 can collide with the inner wall of the mixing channel 310 after flushing into the mixing channel 310, so as to facilitate the dissolution of the detergent.

[0060] In some embodiments, a flushing water inlet 321 is provided at the input end of the flushing channel 320, and the aperture of the flushing water inlet 321 is larger than the aperture of the detergent inlet 311, so that at the same time, the total amount of water entering the mixing channel 310 is greater than the total amount of detergent, so as to facilitate water flushing and stirring of the detergent.

[0061] In other embodiments, the input end of the flushing channel 320 is connected to the output end of the mixing channel 310 , and the flushing channel 320 and the output end of the mixing channel 310 extend in the same direction. The detergent inlet 311 is located at the intersection of the mixing channel 310 and the flushing channel 320 .

[0062] Figure 7The utility model is a structural schematic diagram of a washing machine when an air inlet pipe is connected to a main water inlet pipe.

[0063] See also Figure 1 and Figure 7 In this embodiment, the second mixing device 400 may include a venturi tube 410 and an air inlet pipe 420. The input end of the venturi tube 410 is connected to the output end of the mixing channel 310, and the output end of the venturi tube 410 is connected to the washing tub 120. The air inlet pipe 420 is connected to the low-pressure area in the venturi tube 410 to input gas into the venturi tube 410 to mix with the mixed liquid.

[0064] The venturi tube 410 may include a contraction portion 411 and an expansion portion 412, wherein the contraction portion 411 is connected to the expansion portion 412. In the direction from the contraction portion 411 to the expansion portion 412, the radial dimension of the contraction portion 411 gradually decreases, and the radial dimension of the expansion portion 412 gradually increases. The end of the contraction portion 411 away from the expansion portion 412 is connected to the output end of the mixing channel 310, and the end of the expansion portion 412 away from the contraction portion 411 is connected to the washing tub 120. After passing through the contraction portion 411 and entering the expansion portion 412, the flow rate of the mixed liquid increases, so that a low-pressure area is formed on the end of the expansion portion 412 of the venturi tube 410 close to the contraction portion 411.

[0065] The air inlet pipe 420 is connected to the low pressure area of ​​the expansion part 412 and communicates with the venturi tube 410. The gas can enter the inside of the venturi tube 410 through the air inlet pipe 420. The gas can be mixed with the high-speed flowing mixed liquid, so that the detergent can be fully dissolved in the water to form washing water and generate a large amount of foam. This can improve the foam formation efficiency of the second mixing device 400, prevent part of the detergent from remaining at the bottom water outlet of the washing tub 120, improve the utilization efficiency of the detergent, and prevent the waste of detergent.

[0066] See also Figure 1 and Figure 7 In this embodiment, the output end of the venturi tube 410 is connected to a connecting pipe 431 and a nozzle 432. The connecting pipe 431 connects the venturi tube 410 and the nozzle 432. The connecting pipe 431 passes through the washing tub 120 and then extends into the rolling tub through the delivery port, so that the nozzle 432 extends into the rolling tub. The nozzle 432 can spray the fully mixed washing water onto the articles in the rolling tub. On the one hand, it can improve the utilization efficiency of the detergent and improve the cleaning efficiency of the articles. On the other hand, when the rolling tub rolls, it does not affect the spraying of washing water from the nozzle 432.

[0067] In some embodiments, after the connecting pipe 431 passes through the door sealing ring 130 , it extends into the rolling barrel through the introduction port to ensure the sealing performance of the door body and the washing barrel 120 .

[0068] In other embodiments, the nozzle 432 is located at the upper part of the rolling barrel so that the washing liquid sprayed by the nozzle 432 can cover the objects, thereby ensuring that the washing water is in full contact with the objects and improving the cleaning efficiency of the objects.

[0070] See also Figure 8 In this embodiment, one end of the air inlet pipe 420 facing away from the venturi tube 410 is connected to the outside to introduce the external gas into the venturi tube 410.

[0071] In some embodiments, a one-way valve 421 is provided on one end of the air inlet pipe 420 away from the venturi tube 410 to prevent the washing water in the venturi tube 410 from being discharged to the outside through the air inlet pipe 420, thereby ensuring the safety, stability and reliability of the second mixing device 400.

This allows the gas in the washing tub 120 to enter the venturi tube 410 through the air inlet pipe 420 .

[0076] In other embodiments, one end of the air inlet pipe 420 facing away from the venturi tube 410 is connected to the main water inlet pipe 500 so as to input the gas in the main water inlet pipe 500 into the venturi tube 410 .

[0077] In some embodiments, the second mixing device 400 may include a stirring structure (not shown in the figure), which is disposed at the output end of the expansion portion 412 to stir the washing water output by the venturi tube 410, so that the detergent is fully dissolved in the water.

[0086] The water inlet valve 610 is opened to allow water from the outside to supply water to the flushing channel 320 through the water inlet pipe 620. The conveying device 210 inputs the detergent in the detergent storage box 200 to the input end of the mixing channel 310 through the detergent inlet 311. The water in the flushing channel 320 is input into the mixing channel 310 to flush the detergent. After the water and the detergent are mixed, they impact and collide on the inner peripheral wall of the mixing channel 310.

[0087] After water and detergent are mixed into a mixed liquid in the mixing channel 310 , the mixed liquid is input into the second mixing device 400 through the mixed liquid outlet 312 .

[0088] The mixed liquid entering the second mixing device 400 passes through the contraction part 411 and then enters the expansion part 412, so that the washing liquid is dissolved in the water again. The mixed liquid after entering the expansion part 412 is mixed with the gas input by the air inlet pipe 420, so that the gas and the mixed liquid are mixed again for a second time. The detergent is fully dissolved and foam is formed, thereby effectively improving the efficiency of foam formation. It can also prevent part of the detergent from remaining at the bottom water outlet of the washing drum, improve the utilization efficiency of the detergent, and prevent the waste of detergent.

[0089] In the present application, when the washing machine is in use, the articles are first placed in the washing tub 120. Afterwards, the detergent in the detergent storage box 200 enters the mixing channel 310, and the external water is flushed into the mixing channel 310 through the flushing channel 320, and the water and the detergent are mixed to form a mixed liquid. The first mixing device 300 outputs the mixed liquid to the second mixing device 400, and the mixed liquid and the gas are mixed for a second time in the second mixing device 400, so that the detergent can be fully dissolved to form foam, improve the efficiency of foam formation, and prevent part of the detergent from remaining at the bottom water outlet of the washing tub 120, thereby improving the utilization efficiency of the detergent and preventing the waste of the detergent.
