Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing equipment, in particular to a clothing processing equipment. Background Art

[0002] Clothes treatment equipment primarily washes clothes by mixing water and detergent in an inner drum. When too many clothes are loaded, the wash cycle can begin before the clothes are fully soaked, affecting the wash cycle.

[0068] The following is based on Figures 1 to 11 The clothes processing device of the present invention is described in detail.

[0069] In this embodiment, if Figure 1 and Figure 2As shown, the laundry treatment apparatus 100 includes a circulating water circuit 1, a treatment drum 2, and a microbubble generating device 3. The treatment drum 2 includes a laundry treatment chamber 21 and an inlet 22, through which a user can place laundry. The microbubble generating device 3 includes a microbubble generating tank 31. The treatment drum 2 and the microbubble generating tank 31 are respectively located on the circulating water circuit 1, and the microbubble 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 inlet into the treatment drum 2 reaches a preset value, the circulating water circuit 1 starts the water 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 treatment drum 2 through the circulating water circuit 1.

[0071] In the above technical solution, a microbubble generator 3 is provided upstream of the treatment drum 2 to supply water containing microbubbles to the treatment drum 2. During washing, the microbubbles can carry detergent deep into the interfiber spaces of clothing, removing stubborn stains and effectively removing dirt. This fully utilizes the detergent, reduces the amount of detergent remaining on clothing, and improves the washing effect. During rinsing, the microbubbles carry water deep into the interfiber spaces of clothing, facilitating the rapid removal of residual detergent, thereby shortening the clothing treatment time and saving water. Furthermore, the microbubbles have a large surface area and excellent surface adsorption properties, easily generating hydroxyl groups, which have a strong oxidizing effect and can have a bactericidal effect.

[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 arranged along the water flow direction in the circulating water circuit 1. The first pump body 32 is used to increase the water pressure. Powered by the first pump body 32, the water in the circulating water circuit 1 can quickly enter the microbubble generating tank 31. The water collides multiple times with the air inside the tank and the tank wall, forming bubbles under the action of shear force. Furthermore, the first pump body 32 can be used to control the microbubble production rate and size. Furthermore, the first pump body 32 is a plunger pump or a booster pump.

[0073] In one embodiment, if Figure 1 、 Figure 2 and Figure 11As shown, the clothing processing device 100 further includes a spraying member 4, the nozzle of the spraying member 4 is located in the clothing processing chamber 21, and the spraying member 4 is used to spray water into the clothing processing chamber 21. Specifically, the clothing processing device 100 further includes an outer drum (not shown in the figure), the processing drum 2 is located in the outer drum, and a water-containing chamber is formed between the processing drum 2 and the outer drum. There are two ways to introduce the water flow in the tap water waterway or the circulating waterway 1 into the processing drum 2. The first way is that the water flow first enters the water-containing chamber between the processing drum 2 and the outer drum, and then enters the clothing processing chamber 21 through the through hole on the processing drum 2. The second way is that the water flow is sprayed on the clothes in the clothing processing 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 processing time can be shortened, and water resources can be saved.

[0074] like Figure 2 As shown, the circulating water circuit 1 includes an inlet waterway 11 and an outlet waterway 12. The outlet end of the inlet waterway 11, the laundry treatment chamber 21, the outlet waterway 12, and the inlet end of the inlet waterway 11 are sequentially connected. The inlet waterway 11 is used to introduce water into the treatment drum 2, and the outlet waterway 12 is connected to the drain outlet of the treatment drum 2 to discharge water discharged from the treatment drum 2. The inlet waterway 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 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 spray element 4. In this way, the laundry treatment program of the laundry treatment device 100 includes a microbubble washing mode and a spray mode. When the microbubble washing mode is activated, the first water inlet branch 111 is open and the second water inlet branch 112 is closed. Water in the first water inlet branch 111 flows through the microbubble generating tank 31, forming a water flow containing microbubbles, which is then introduced into the treatment drum 2. When the spray mode is activated, the first water inlet branch 111 is closed and the second water inlet branch 112 is open. Water in the second water inlet branch 112 is sprayed onto the clothes in the clothing treatment chamber 21 through the spray element 4.

[0075] Specifically, in one embodiment, Figure 2 As shown, the 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 in the first water inlet branch 111 flows through the micro-bubble generating tank 31, forming a water flow containing microbubbles, which then flows into the water holding chamber between the treatment tub 2 and the outer tub, and then flows into the clothing treatment chamber 21 to treat the clothes.

[0076] In another embodiment, the water outlet of the first water inlet branch 111 is connected to the spraying element 4. When the micro-bubble washing mode is turned on, the water 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 clothing processing chamber 21 through the spraying element 4. Figure 1 As shown, the water outlet 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 spraying member 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 respectively 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 microbubble 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. Furthermore, 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 located on the main water inlet path 113. Thus, the first pump body 32 serves two functions: first, it provides power for the water flow in the first water inlet branch 111, i.e., it provides water flow power for the microbubble washing mode, facilitating the rapid generation of microbubbles; second, it provides power for the water flow in the second water inlet branch 112, i.e., it provides water flow power for the spray mode, facilitating high-pressure spraying. This solution's first pump body 32 serves two purposes, eliminating the need for an additional pump body to provide water flow power for the spray mode, reducing the number of components and saving space.

[0080] In one embodiment, if Figure 1 、 Figure 2 and Figure 4As shown, the clothing treatment apparatus 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 outlet end of the outlet waterway 12, and the first water outlet 522 is connected to the inlet end of the inlet waterway 11. The filter 523 is located between the first water inlet 521 and the first water outlet 522. During clothing treatment, water discharged from the treatment tub 2 enters the second valve body 52 via the outlet waterway 12 and the first water inlet 521 in sequence. After being filtered by the filter 523 in the second valve body 52, the water enters the main water inlet 113 of the inlet waterway 11 through the first water outlet 522, and is then introduced into the treatment tub 2 via the first water inlet branch 111 or the second water inlet branch 112, forming 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. The second water inlet 524 is connected to the cleaning pipeline 8 (such as a tap water pipe). In this embodiment, 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, and the second water inlet 524 is connected to the second water outlet 525 to form a valve body branch channel. The cleaning pipeline 8 introduces cleaning water into the second water inlet 524. The cleaning water rinses the filter 523 and is discharged from the second water outlet 525, achieving self-cleaning.

[0082] Furthermore, the direction of water flow in the valve body's branch channel when passing through the filter 523 is opposite to the direction of water flow in the valve body's main channel when passing through the filter 523. Specifically, the filter 523 has two back-to-back surfaces, a first surface wall 5231 and a second surface wall 5232. When the laundry treatment program is activated, the water first contacts the first surface wall 5231 and then passes through the filter holes. Impurities (such as hair and dirt) filtered out accumulate on the first surface wall 5231 or become clogged in the filter holes. Thus, when the self-cleaning function is activated, the water first contacts the second surface wall 5232 and then passes through the filter holes, flushing the filter holes before flushing the first surface wall 5231. That is, the first surface wall 5231 is located downstream of the filter holes, and the impurities flushed from the first surface wall 5231 by the water flow will not clog the filter holes again, ensuring a self-cleaning effect.

[0083] Furthermore, the second surface wall 5232 is located above the first surface wall 5231. In this way, 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. 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 draining the sewage from the treatment drum 2. When the clothing treatment program is started, the first pump body 32 is in operation and the second pump body 6 is in operation. The water in the treatment drum 2 is discharged from the drain outlet, enters the second pump body 6 through the water outlet waterway 12, and then enters the second valve body 52. ​​After being filtered by the filter 523 in the second valve body 52, it enters the water inlet waterway 11. When the clothing treatment program (such as the washing program or the rinsing program) ends and the sewage in the treatment drum 2 needs to be drained, the first pump body 32 stops and the second pump body 6 is opened 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 a miniaturized design of the clothing processing apparatus 100 .

[0085] Furthermore, a filtering structure (not shown in the figures) is provided in the second pump body 6 , and during the process of treating 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. The torrent structure 312 is located in the generating chamber 311. When the water in the first water inlet branch 111 enters the generating chamber 311 through the third water inlet 313, the water collides with the air inside the tank and the tank wall multiple times to form small bubbles. In addition, the water can also collide with the torrent structure 312, increasing the gas-liquid contact area, thereby increasing the solubility of air in water, promoting the dissolution of air in the water, and quickly forming 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, which are spaced apart in a first direction a. The first direction a is perpendicular to the direction of water flow in the generating chamber 311. The gap 3122 between adjacent rapid flow plates 3121 allows water to flow through. In this embodiment, because the distribution direction (first direction a) of the two rapid flow plates 3121 is perpendicular to the direction of water flow in the generating chamber 311, most of the water entering the generating chamber 311 first strikes the surface of the rapid flow plates 3121 before passing through the gap 3122. The water flow becomes smaller and then larger, further increasing the gas-liquid contact area and the gas dissolution rate. Of course, the first direction a does not need to be perpendicular to the direction of water flow in the generating chamber 311. The two directions can intersect so that part of the water flow can strike the surface of the rapid flow plates 3121. Of course, the number of rapid flow plates 3121 is not limited to two, but 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. The ribs 31211 are used to disperse the water flow in the generating chamber 311, thereby further increasing the gas-liquid contact area and improving the gas dissolution rate. The ribs 31211 can extend vertically, vertically, or horizontally. The shape of the ribs 31211 is not limited to regular or irregular shapes such as elongated strips, rings, waves, or grids.

[0089] In one embodiment, if Figures 6 to 8 As shown, there are two turbulent flow structures 312, located at the upper and lower portions of the generating chamber 311, respectively. The turbulent flow structure 312 located at the upper portion of the generating chamber 311 can collide with the water flow at the upper portion of the generating chamber 311, while the turbulent flow structure 312 located at the lower portion of the generating chamber 311 can collide with the water flow at the lower portion of the generating chamber 311, thereby increasing the gas-liquid contact area. Of course, the number of turbulent flow structures 312 is not limited to two, and may 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 in the process of 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 facilitates the water entering the generating chamber 311 to first collide with the tank wall multiple times before falling. Furthermore, the third water inlet 313 and the third water outlet 314 are spaced apart along the water flow direction. This height difference and the water flow velocity difference between the third water inlet 313 and the third water outlet 314 create a water seal at the third water outlet 314, thereby increasing the pressure in the generating chamber 311 to form a high-pressure chamber, further increasing the dissolved gas concentration.

[0093] Furthermore, if Figure 5 and Figure 8 As shown, the rapid flow structure 312 located at the upper portion of the generating chamber 311 is arranged near 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 portion of the generating chamber 311 is arranged near 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 portion 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 portion of the generating chamber 311. 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 Figure 9 As shown, the microbubble generating tank 31 includes a water inlet 315, the inlet end of the water inlet 315 is provided with a snap structure 3151, and the outlet end of the water inlet 315 is formed with a narrowing channel 3152, which 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 microbubble generating tank 31 via 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 snap structure 3151, it is tightened 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 Figure 10As shown, the microbubble generating tank 31 includes a water outlet 316, which is a Venturi tube structure and has a second threaded structure 3162. The water outlet 316 is threadedly connected to the microbubble generating tank 31 via the second threaded structure 3162. Specifically, the water outlet 316 includes a plurality of water outlet channels 3161, which include a first channel 31611, a second channel 31612, and a third channel 31613 that are sequentially connected along the water flow direction. The first channel 31611 is connected to the generating chamber 311. The first channel 31611 gradually narrows along the direction of water flow, the cross-sectional areas of each part of the second channel 31612 are equal, and the third channel 31613 gradually expands along the direction of water flow. In this way, when the water flow in the generating chamber 311 flows into the water outlet part 316, the water flow first passes through the first channel 31611, the flow rate increases and negative pressure is generated, which makes the air solubility in the water flow smaller, and the air precipitates from the solute state to form microbubbles. In addition, the small bubbles generated in the generating chamber 311 will be broken and split in the water outlet channel 3161 to form microbubbles of smaller size.

[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, and the first tank body 317 is sealed and connected to the second tank body 318, and encloses a generating chamber 311. Specifically, the first tank body 317 is located above the second tank body 318, and the first tank body 317 is provided with a plurality of first mounting holes 3171, and the second tank body 318 is provided with a plurality of second mounting holes 3181. 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, and 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. The electromagnetic ventilation valve 319 controls the start and stop of air intake. 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 it can no longer generate bubbles. Then, the electromagnetic ventilation valve 319 is opened to replenish air into 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 exhausting 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. The liquid and air in the generating chamber 311 cannot be discharged to prevent leakage.

[0098] Furthermore, due to the high pressure inside the microbubble generating tank 31, the microbubble generating tank 31 will be in a high-frequency vibration state during operation, which is easy to come into contact with surrounding components, and 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 Figure 11 As shown, the spray element 4 includes a bayonet 41 and a nozzle end 42. The bayonet 41 is connected to the sixth water pipe 76 and secured with a clamp. The nozzle end 42 has a fan-shaped structure. A larger fan angle increases the spray range, but the impact force decreases. Therefore, the fan angle is limited to between 45° and 120°. In addition, the nozzle end 42 is positioned at an angle of 10° to 30° with the horizontal plane to achieve a better spray 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.
