[0068] According to the following Figures 1 to 11 The clothes treating apparatus of the present invention will be described in detail.

[0069] In this embodiment, if Figure 1 and Figure 2As shown, the clothes treatment device 100 includes a circulating water circuit 1, a treatment drum 2 and a micro-bubble generating device 3. The treatment drum 2 includes a clothes treatment chamber 21 and a loading port 22. The user can place clothes in the clothes treatment chamber 21 from the loading port 22. The micro-bubble generating device 3 includes a micro-bubble generating tank 31. The treatment drum 2 and the micro-bubble generating tank 31 are respectively located on the circulating water circuit 1, and the micro-bubble generating tank 31 is located upstream of the treatment drum 2.

[0070] When the clothing processing device 100 starts the clothing processing program, after the water intake in the processing drum 2 reaches a preset value, the circulating water circuit 1 starts the water circuit circulation, and the water circulates in the circulating water circuit 1. Before entering the clothing processing chamber 21, the water in the circulating water circuit 1 first enters the microbubble generating tank 31 to form a water flow containing microbubbles. Then, the water flow containing microbubbles is introduced into the processing drum 2 through the circulating water circuit 1.

[0071] In the above technical solution, a microbubble generating device 3 is arranged upstream of the treatment tube 2 to supply a water flow containing microbubbles to the treatment tube 2. When washing, the microbubbles can carry detergent deep into the fiber gaps of the clothes, remove stubborn stains, efficiently remove dirt, make full use of detergents, reduce the amount of detergent residue on the clothes, and improve the washing effect. When rinsing, the microbubbles carry water deep into the fiber gaps of the clothes, which is conducive to quickly removing the residual detergent on the clothes, thereby shortening the clothing processing time and saving water. In addition, the microbubbles have a large surface area, excellent surface adsorption properties, are easy to produce hydroxyl groups, have a strong oxidizing effect, and can play a bactericidal role.

[0072] In one embodiment, if Figure 2 and Figure 3 As shown, the microbubble generating device 3 also includes a first pump body 32. The first pump body 32 and the microbubble generating tank 31 are sequentially distributed on the circulating water circuit 1 along the water flow direction. The first pump body 32 is used to increase the water pressure of the water flow. The water flow in the circulating water circuit 1 can quickly enter the microbubble generating tank 31 under the power provided by the first pump body 32. The water flow collides with the air in the tank and the tank wall for many times, and bubbles are formed under the action of shear force. In addition, the first pump body 32 can be used to control the microbubble yield and the size of the microbubbles. Further, the first pump body 32 is a plunger pump or a booster pump.

[0073] In one embodiment, if Figure 1 , Figure 2 and Fig.11As shown, the clothing treatment device 100 further includes a spraying member 4, the nozzle of which is located in the clothing treatment chamber 21, and the spraying member 4 is used to spray water into the clothing treatment chamber 21. Specifically, the clothing treatment device 100 further includes an outer cylinder (not shown in the figure), the treatment cylinder 2 is located in the outer cylinder, and a water containing chamber is formed between the treatment cylinder 2 and the outer cylinder. There are two ways to introduce the water flow in the tap water circuit or the circulating water circuit 1 into the treatment cylinder 2. The first way is that the water flow first enters the water containing chamber between the treatment cylinder 2 and the outer cylinder, and then enters the clothing treatment chamber 21 through the through hole on the treatment cylinder 2. The second way is that the water flow is sprayed on the clothing in the clothing treatment chamber 21 through the spraying member 4, which is not affected by the water pressure of the use scene. Through high-pressure spraying, the detergent can be fully mixed, the detergent residue can be reduced, the clothing treatment time can be shortened, and water resources can be saved.

[0074] like Figure 2 As shown, the circulating water circuit 1 includes an inlet water circuit 11 and an outlet water circuit 12. The outlet end of the inlet water circuit 11, the laundry processing chamber 21, the outlet water circuit 12 and the inlet end of the inlet water circuit 11 are connected in sequence. The inlet water circuit 11 is used to introduce water flow into the processing drum 2. The outlet water circuit 12 is connected to the drain port of the processing drum 2 to guide the water discharged from the processing drum 2. The inlet water circuit 11 includes a first inlet branch 111 and a second inlet branch 112. The microbubble generating tank 31 is located on the first inlet branch 111. The water flow in the second inlet branch 112 does not flow through the microbubble generating tank 31. The outlet end of the second inlet branch 112 is connected to the spraying member 4. In this way, the laundry processing program of the laundry processing device 100 includes a microbubble washing mode and a spraying mode. When the microbubble washing mode is turned on, the first water inlet branch 111 is in an open state, the second water inlet branch 112 is in a closed state, and the water in the first water inlet branch 111 flows through the microbubble generating tank 31, forms a water flow containing microbubbles, and then is introduced into the treatment drum 2. When the spray mode is turned on, the first water inlet branch 111 is in a closed state, the second water inlet branch 112 is in an open state, and the water in the second water inlet branch 112 is sprayed on the clothes in the clothes treatment chamber 21 through the spray part 4.

[0075] Specifically, in one embodiment, Figure 2 As shown, the water outlet end of the first water inlet branch 111 is connected to the treatment tub 2. When the micro-bubble washing mode is turned on, the water flow in the first water inlet branch 111 flows through the micro-bubble generating tank 31, forms a water flow containing micro-bubbles, flows into the water containing cavity between the treatment tub 2 and the outer tub, and then flows into the clothing treatment cavity 21 to treat the clothing.

[0076] In another embodiment, the water outlet of the first water inlet branch 111 is connected to the spraying member 4. When the micro-bubble washing mode is turned on, the water flow in the first water inlet branch 111 flows through the micro-bubble generating tank 31, and after forming a water flow containing micro-bubbles, it is sprayed on the clothes in the clothes processing chamber 21 through the spraying member 4. Figure 1 As shown, the water outlet part 316 of the microbubble generating tank 31 is connected to an inlet of the third valve body 53 through the seventh water pipe 77 , and the outlet of the third valve body 53 is connected to the spray part 4 through the sixth water pipe 76 .

[0077] In another embodiment, the water outlet end of the first water inlet branch 111 can be divided into two paths, one water path is connected to the treatment drum 2, and the other water path is connected to the spray element 4, forming a normal microbubble washing mode and a spray microbubble washing mode. Any microbubble washing mode can be used to process clothes according to the user's choice.

[0078] Furthermore, if Figure 2 and Figure 3 As shown, the clothing processing device 100 also includes a first valve body 51, and the water inlet water path 11 also includes a main water inlet path 113. The water outlet end of the main water inlet path 113 is connected to the first water inlet branch 111 and the second water inlet branch 112 through the first valve body 51. When the first valve body 51 connects the main water inlet path 113 with the first water inlet branch 111, the clothing processing device 100 performs a micro-bubble washing mode. When the first valve body 51 connects the main water inlet path 113 with the second water inlet branch 112, the clothing processing device 100 performs a spray mode. Further, the first valve body 51 is a reversing valve for controlling the on-off of the first water inlet branch 111 and the second water inlet branch 112.

[0079] In one embodiment, if Figure 2 As shown, the first pump body 32 of the microbubble generating device 3 is arranged on the main water inlet path 113. In this way, the first pump body 32 plays two roles. On the one hand, it provides power for the water flow in the first water inlet branch 111, that is, it provides water flow power for the microbubble washing mode to facilitate the rapid generation of microbubbles. On the other hand, it provides power for the water flow in the second water inlet branch 112, that is, it provides water flow power for the spray mode to facilitate high-pressure spraying. The first pump body 32 of this solution is a dual-purpose pump, and there is no need to set up an additional pump body to provide water flow power for the spray mode, which reduces the number of parts and saves space.

[0080] In one embodiment, if Figure 1 , Figure 2 and Figure 4As shown, the clothing treatment device 100 further includes a second valve body 52, which includes a first water inlet 521, a first water outlet 522 and a filter 523. The first water inlet 521 is connected to the water outlet end of the water outlet waterway 12, the first water outlet 522 is connected to the water inlet end of the water inlet waterway 11, and the filter 523 is located between the first water inlet 521 and the first water outlet 522. During the clothing treatment process, the water flow discharged from the treatment tub 2 enters the second valve body 52 via the water outlet waterway 12 and the first water inlet 521 in sequence, and after being filtered by the filter 523 in the second valve body 52, the water flow enters the main water inlet path 113 of the water inlet waterway 11 through the first water outlet 522, and then is introduced into the treatment tub 2 via the first water inlet branch 111 or the second water inlet branch 112 to form a circulating waterway.

[0081] Furthermore, if Figure 2 and Figure 4 As shown, the second valve body 52 also includes a second water inlet 524 and a second water outlet 525, the filter 523 is located between the second water inlet 524 and the second water outlet 525, and the second water inlet 524 is connected to the cleaning pipeline 8 (such as a tap water pipe). In this solution, the second valve body 52 is a four-way valve structure. When the first water inlet 521 is connected to the first water outlet 522 to form a valve body main channel, the circulating water circuit 1 is opened, and the clothing treatment device 100 can start the clothing treatment program; when the clothing treatment program ends, the valve body main channel is closed, the second water inlet 524 is connected to the second water outlet 525 to form a valve body branch channel, and the cleaning pipeline 8 introduces cleaning water to the second water inlet 524. The cleaning water rinses the filter 523 and is discharged from the second water outlet 525 to achieve self-cleaning.

[0082] Furthermore, the direction of the water flow in the branch channel of the valve body when flowing through the filter 523 is opposite to the direction of the water flow in the main channel of the valve body when flowing through the filter 523. Specifically, the filter 523 has two first surface walls 5231 and second surface walls 5232 arranged in opposite directions. When the clothes treatment program is turned on, the water first contacts the first surface wall 5231 and then passes through the filter hole. The impurities (such as hair and dirt) filtered out are accumulated on the first surface wall 5231 or blocked in the filter hole. In this way, when the self-cleaning is turned on, the water first contacts the second surface wall 5232 and then passes through the filter hole. After flushing the filter hole, the first surface wall 5231 is flushed. That is, the first surface wall 5231 is located downstream of the filter hole. The impurities flushed from the first surface wall 5231 by the water flow will not block the filter hole again, ensuring the self-cleaning effect.

[0083] Furthermore, the second surface wall 5232 is located above the first surface wall 5231, so that during the self-cleaning process, impurities on the first surface wall 5231 can fall off quickly after being rinsed and discharged through the second water outlet 525, thereby improving the cleaning effect.

[0084] In one embodiment, if Figure 1 and Figure 2 As shown, the microbubble generating device 3 also includes a second pump body 6, the water inlet of the second pump body 6 is connected to the water outlet end of the water outlet waterway 12, and the water outlet of the second pump body 6 is connected to the first water inlet 521 of the second valve body 52 through the first water pipe 71. The second pump body 6 is used to provide power for the treatment drum 2 to discharge sewage. When the clothing treatment program is turned on, the first pump body 32 is running, and the second pump body 6 is not running. The water in the treatment drum 2 is discharged from the drain port, and enters the second pump body 6 through the water outlet waterway 12 and then enters the second valve body 52, and enters the water inlet waterway 11 after being filtered by the filter 523 in the second valve body 52. ​​When the clothing treatment program (such as a washing program or a rinsing program) ends and the sewage in the treatment drum 2 needs to be discharged, the first pump body 32 stops running, and the second pump body 6 is turned on to pump out the sewage in the treatment drum 2 and discharge it through the second water outlet 525 of the second valve body 52. In this solution, the second pump body 6 is integrated into the circulating water circuit 1 , which is beneficial to simplifying the water circuit and facilitating the miniaturization design of the clothing processing device 100 .

[0085] Furthermore, a filtering structure (not shown in the figure) is provided in the second pump body 6 , and during the process of treating the clothes, the filtering structure can preliminarily filter the water flow in the water outlet waterway 12 .

[0086] In one embodiment, if Figures 5 to 8 As shown, the microbubble generating tank 31 includes a generating chamber 311, a torrent structure 312, a third water inlet 313 and a third water outlet 314, and the torrent structure 312 is located in the generating chamber 311. When the water flow in the first water inlet branch 111 enters the generating chamber 311 through the third water inlet 313, the water flow collides with the air in the tank and the tank wall for many times to form small bubbles. In addition, the water flow can also collide with the torrent structure 312 to increase the gas-liquid contact area, thereby increasing the solubility of air in water, so as to promote the air to dissolve in the water flow and quickly form a water flow containing small bubbles.

[0087] Furthermore, if Figure 6 and Figure 7As shown, the rapid flow structure 312 includes two rapid flow plates 3121, and the two rapid flow plates 3121 are distributed in sequence along the first direction a, and the first direction a is perpendicular to the flow direction of the water in the generating chamber 311, and the gap 3122 between the two adjacent rapid flow plates 3121 is for the water to pass through. In this solution, since the distribution direction (first direction a) of the two rapid flow plates 3121 is perpendicular to the flow direction of the water in the generating chamber 311, most of the water enters the generating chamber 311 and first hits the surface of the rapid flow plate 3121, and then passes through the gap 3122, and the water flow becomes smaller and then larger, so as to further increase the gas-liquid contact area and improve the gas dissolution rate. Of course, the first direction a may not be perpendicular to the flow direction of the water in the generating chamber 311, and the two directions may intersect so that part of the water flow can hit the surface of the rapid flow plate 3121. Of course, the number of rapid flow plates 3121 is not limited to two, and can also be three or even more.

[0088] Furthermore, if Figures 6 to 8 As shown, ribs 31211 are provided on both sides of the agitator plate 3121, and the ribs 31211 are used to disperse the water flow in the generating chamber 311, so as to further increase the gas-liquid contact area and increase the gas dissolving speed. The ribs 31211 can extend in the vertical direction, can extend obliquely in the up-down direction, and can extend in the horizontal direction, and the shape of the ribs 31211 is not limited to regular shapes or irregular shapes such as strips, rings, waves, and grids.

[0089] In one embodiment, if Figures 6 to 8 As shown, there are two torrent structures 312, which are respectively located at the upper and lower parts of the generating chamber 311. The torrent structure 312 located at the upper part of the generating chamber 311 can collide with the water flow at the upper part of the generating chamber 311, and the torrent structure 312 located at the lower part of the generating chamber 311 can collide with the water flow at the lower part of the generating chamber 311, so as to increase the gas-liquid contact area. Of course, the number of torrent structures 312 is not limited to two, and can also be three or even more.

[0090] Furthermore, if Figures 6 to 8 As shown, the two rapid flow structures 312 are respectively connected to the top cavity wall and the bottom cavity wall of the generating cavity 311, and the side walls of the rapid flow structure 312 connected to the bottom cavity wall of the generating cavity 311 are respectively connected to the side cavity walls of the generating cavity 311, so that the water flow located at the lower part of the generating cavity 311 can only pass through the gap 3122 of the rapid flow structure 312.

[0091] Furthermore, if Figure 8 As shown, the two rapid flow structures 312 are staggered along the flow direction of the water in the generating chamber 311 , so that the water can collide with the two rapid flow structures 312 multiple times during the process of the water flowing toward the third water outlet 314 .

[0092] In one embodiment, if Figure 5 As shown, the third water inlet 313 is located above the third water outlet 314, which is conducive to the water flow entering the generating chamber 311 to collide with the tank wall multiple times before falling. In addition, the third water inlet 313 and the third water outlet 314 are spaced apart and distributed along the flow direction of the water flow, so that the height difference and water flow velocity difference between the third water inlet 313 and the third water outlet 314 will form a water seal at the third water outlet 314, thereby increasing the pressure in the generating chamber 311 to form a high-pressure chamber, so as to further increase the solubility of gas.

[0093] Furthermore, if Figure 5 and Figure 8 As shown, the rapid flow structure 312 located at the upper part of the generating chamber 311 is arranged close to the third water inlet 313, so that the water flow entering from the third water inlet 313 can effectively collide with the rapid flow structure 312. The rapid flow structure 312 located at the lower part of the generating chamber 311 is arranged close to the third water outlet 314, so that the water flow entering from the third water inlet 313 collides with the tank wall and the rapid flow structure 312 located at the upper part of the generating chamber 311, and falls on the bottom wall of the generating chamber 311, and then flows to the rapid flow structure 312 located at the lower part of the generating chamber 311, and after colliding with the rapid flow structure 312, the water flow can only pass through the gap 3122 of the rapid flow structure 312.

[0094] In one embodiment, if Figure 3 and Fig. 9 As shown, the micro-bubble generating tank 31 includes a water inlet 315, the inlet end of the water inlet 315 is provided with a buckle structure 3151, the outlet end of the water inlet 315 is formed with a narrowing channel 3152, the narrowing channel 3152 is connected to the generating chamber 311, the outer wall of the water inlet 315 is provided with a first threaded structure 3153, and the water inlet 315 is screwed to the micro-bubble generating tank 31 through the first threaded structure 3153. The first water outlet 522 of the second valve body 52 is connected to the inlet end of the water inlet 315 through the fourth water pipe 74, and after the fourth water pipe 74 is connected to the buckle structure 3151, it is fastened by a hoop to prevent water leakage. The narrowing channel 3152 gradually narrows along the flow direction of the water, so that the water flow entering the generating chamber 311 has a certain initial velocity.

[0095] In one embodiment, if Figure 3 and Fig.10As shown, the micro-bubble generating tank 31 includes a water outlet 316, the water outlet 316 is a venturi tube structure, the water outlet 316 is provided with a second threaded structure 3162, and the water outlet 316 is screwed to the micro-bubble generating tank 31 through the second threaded structure 3162. Specifically, the water outlet 316 includes a plurality of water outlet channels 3161, and the water outlet channels 3161 include a first channel 31611, a second channel 31612, and a third channel 31613 that are sequentially connected along the water flow direction, and the first channel 31611 is connected to the generating chamber 311. The first channel 31611 gradually narrows along the flow direction of the water, the cross-sectional areas of each part of the second channel 31612 are equal, and the third channel 31613 gradually expands along the flow direction of the water. In this way, when the water in the generating chamber 311 flows into the water outlet 316, the water first passes through the first channel 31611, the flow rate increases and negative pressure is generated, so that the air solubility in the water becomes smaller, and the air precipitates from the solute state to form microbubbles, and the small bubbles generated in the generating chamber 311 will be broken and split in the water outlet channel 3161 to form smaller microbubbles.

[0096] In one embodiment, if Figures 5 to 8 As shown, the microbubble generating tank 31 includes a first tank body 317 and a second tank body 318, the first tank body 317 and the second tank body 318 are sealed and connected, and enclosed to form a generating chamber 311. Specifically, the first tank body 317 is located above the second tank body 318, the first tank body 317 is provided with a plurality of first mounting holes 3171, the second tank body 318 is provided with a plurality of second mounting holes 3181, and the first mounting holes 3171 and the second mounting holes 3181 are aligned one by one and fixed by screws (not shown in the figure). The bottom wall of the first tank body 317 is provided with a circle of protrusions 3172, and the top wall of the second tank body 318 is provided with a circle of grooves 3182, the protrusions 3172 are inserted into the grooves 3182, and a sealing ring (not shown in the figure) is clamped in the groove 3182, and the assembly gap between the first tank body 317 and the second tank body 318 is sealed by the sealing ring. The third water inlet 313 is disposed on one side of the first tank body 317 , and the third water outlet 314 is disposed on one side of the second tank body 318 .

[0097] Furthermore, if Figure 3 , Figure 5 , Figure 6 and Figure 8As shown, the first tank body 317 is provided with a vent 3173, and an electromagnetic ventilation valve 319 is installed at the vent 3173, and the start and stop of air intake is controlled by the electromagnetic ventilation valve 319. Specifically, after the microbubble generating device 3 has been running for a period of time, the air in the microbubble generating tank 31 is consumed to the point where bubbles can no longer be generated. Then, the electromagnetic ventilation valve 319 is opened to replenish air for the generating chamber 311. In addition, when the microbubble generating device 3 stops running, the electromagnetic ventilation valve 319 also needs to be opened to assist in discharging the remaining air in the generating chamber 311. It should be understood that the electromagnetic ventilation valve 319 is a one-way passage that can only allow air to enter, and the liquid and air in the generating chamber 311 cannot be discharged to prevent leakage.

[0098] Furthermore, since the pressure inside the microbubble generating tank 31 is relatively high, the microbubble generating tank 31 will be in a high-frequency vibration state during operation, and it is easy to come into contact with surrounding components. The microbubble generating tank 31 itself may also be in a resonance state. Figure 5 As shown, the surface wall of the first tank body 317 is provided with a plurality of first reinforcing ribs 3174 , and the surface wall of the second tank body 318 is provided with a plurality of second reinforcing ribs 3183 , so as to improve the structural strength of the microbubble generating tank 31 .

[0099] In one embodiment, if Figure 1 and Fig.11 As shown, the spraying member 4 includes a bayonet 41 and a nozzle end 42. The bayonet 41 is connected to the sixth water pipe 76 and fastened by a clamp. The nozzle end 42 is fan-shaped. The larger the fan angle, the wider the spray range, but the impact force will decrease. Therefore, the fan angle is limited to between 45° and 120°. In addition, the angle between the nozzle end 42 and the horizontal plane is 10° to 30° to form a better spraying effect.

[0100] In one embodiment, the circulating water circuit 1 includes a plurality of water pipes, specifically, Figure 1 , Figure 3 and Figure 4As shown, the interface 61 of the second pump body 6 is connected to the first water inlet 521 of the second valve body 52 through the first water pipe 71, the first water outlet 522 of the second valve body 52 is connected to the pump inlet 321 of the first pump body 32 through the second water pipe 72, the pump outlet 322 of the first pump body 32 is connected to the valve inlet 511 of the first valve body 51 through the third water pipe 73, the first valve outlet 512 of the first valve body 51 is connected to the water inlet part 315 of the microbubble generating tank 31 through the fourth water pipe 74, the second valve outlet 513 of the first valve body 51 is connected to the inlet of the third valve body 53 through the fifth water pipe 75, the outlet of the third valve body 53 is connected to the spray part 4 through the sixth water pipe 76, the water outlet part 316 of the microbubble generating tank 31 can be connected to another inlet of the third valve body 53 through the seventh water pipe 77, and can also be connected to the treatment cylinder 2 through a water pipe, and the second water outlet 525 of the second valve body 52 is discharged to the outside of the casing through the eighth water pipe 78.
