As commonly used clothing processing equipment in daily life, washing machines, shoe washers and other clothing processing equipment have brought great convenience to people's lives.

[0003] During the operation of the clothing processing equipment, if tap water is used as washing water, the temperature is low and cannot reach the optimal dissolution temperature of the laundry detergent or washing powder, resulting in insufficient dissolution of the laundry detergent and laundry liquid, causing waste of the laundry detergent and laundry liquid, and affecting the cleanliness of the laundry; and the incompletely dissolved laundry detergent and laundry liquid condense on the clothes, making it difficult to rinse, resulting in unclean rinsing and affecting the user experience.

[0044] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0046] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0047] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0048] Before introducing the clothes treating apparatus provided by the present invention, the principle that scale deposition is easily generated in the water inlet assembly of the clothes treating apparatus is first explained.

[0049] Washing water for laundry machines typically comes from tap water. Since tap water generally contains dissolved calcium and magnesium ions, the harder the water, the higher the calcium and magnesium ion content. Therefore, when water is no longer flowing into the laundry machine, the inlet valve upstream of the inlet pipe closes, and the residual water in the pipe immediately stops flowing. When hard tap water remains open and static in the inlet pipe of the laundry machine for a long time, it absorbs gases such as carbon dioxide and sulfur dioxide from the air. These carbon dioxide and sulfur dioxide dissolve in water, producing carbonate and sulfate ions. These ions react with calcium and magnesium ions to produce water-insoluble precipitates such as calcium carbonate, magnesium carbonate, and calcium sulfate. These precipitates accumulate and form scale.

[0050] Therefore, to prevent scale buildup, one approach is to reduce the amount of calcium and magnesium ions in the water, for example by using water softening. Another approach is to reduce the amount of carbon dioxide and sulfur dioxide that cause calcium and magnesium ions to precipitate, which is more difficult. Another approach is to reduce the time it takes for hard water to combine with carbon dioxide and sulfur dioxide, allowing the water to dry before they can react. Even if white powder precipitates, it is readily soluble in water, calcium chloride and magnesium chloride, and will be quickly washed away during the next flush.

[0051] Furthermore, when a bubbler is installed at the outlet of the water inlet pipe, this water will remain in the pipe for a long time due to the thinness of the pipe, the surface tension between the filter and the water, and the influence of atmospheric pressure. The bubbler outlet is located closest to the air, and due to surface tension, a water film easily forms on the filter, which is most likely to absorb acidic gases and deposit scale. Over time, this can cause the filter to become clogged, preventing the release of bubbling water.

[0052] Figure 1 FIG2 shows a schematic structural diagram of a clothes processing device 10 provided according to an exemplary embodiment of the present invention. The clothes processing device 10 is a washing machine, a washer-dryer, a shoe washer, etc., and the present invention is not limited thereto.

[0053] like Figure 1 As shown, the laundry treatment device 10 includes a housing 100, an outer tub 200, an inner tub, and a dispenser box 300 disposed within the housing 100. The front side of the housing 100 is provided with a laundry inlet and a door 400 for opening and closing the inlet. The door 400 is provided with an observation window, and a sealing window gasket 210 is provided between the laundry inlet and the outer tub 200. The inner tub is connected to a drive unit for rotating the inner tub. The top of the outer tub 200 is connected to the dispenser box 300 via a connecting pipe, which is used to dispense laundry treatment agent and wash water into the outer tub 200.

[0054] The housing 100 is also provided with a drainage assembly 500 connected to the outer cylinder 200 for draining the water in the outer cylinder 200. The drainage assembly 500 adopts an upper drainage structure. It is understandable that after the drainage process is completed, the residual water in the drainage assembly 500 of the upper drainage structure can isolate the outer cylinder 200 space from the outside space, preventing the occurrence of odor backflow. As an example, the drainage assembly 500 includes a drainage pump 510, a water diversion pipe 520 and a drainage pipe 530. The water diversion pipe 520 is connected between the outer cylinder 200 and the inlet of the drainage pump 510, and the drainage pipe 530 is connected to the outlet of the drainage pump 510.

[0055] The laundry treatment apparatus 10 further includes a water inlet assembly 600, which comprises a main water inlet pipe 610, a first water inlet branch pipe 620 connected to the water outlet of the main water inlet pipe 610, and a second water inlet branch pipe 630. The first water inlet branch pipe 620 is configured to communicate with the dispenser box 300 to provide water for diluting and rinsing the laundry treatment agent, while the second water inlet branch pipe 630 is configured to provide water for rinsing and cleaning the observation window and / or the sealing window gasket 210. Furthermore, a rinse head is provided at the water outlet of the second water inlet branch pipe 630. The rinse head can be of a commonly used structure in the art and is not limited thereto by the present invention.

[0056] The water inlet main pipe 610 is equipped with a water inlet valve 700 for controlling the on / off operation of the water inlet main pipe 610. It should be noted that before or after the water inlet valve 700 is opened, the first water inlet branch pipe 620 and the second water inlet branch pipe 630 can form a vertically connected structure with one higher and one lower, respectively, and communicate with the atmosphere. In other words, before or after the water inlet valve 700 is opened, no water is present in the first water inlet branch pipe 620 or the second water inlet branch pipe 630.

[0057] As an example, the first water inlet branch pipe 620 includes a main pipe section 621 and a connector section 622 detachably connected to the main pipe section 621. The connector section 622 has a three-way structure. The inlet of the connector section 622 is connected to the water inlet main pipe 610, and the two outlets are connected to the main pipe section 621 of the first water inlet branch pipe 620 and the second water inlet branch pipe 630, respectively. During water inflow, the majority of the water in the water inlet main pipe 610 flows into the first water inlet branch pipe 620 to dilute and rinse the laundry treatment agent. A small amount also flows into the second water inlet branch pipe 630 to rinse and clean the observation window and the window sealing gasket 210.

[0058] A water hammer suppression device 640 is connected in parallel between the water inlet and the water outlet of the water inlet valve 700. The water hammer suppression device 640 is configured to use the impact force generated by the water flow at the water inlet to push the water flow at the water outlet forward when the water inlet valve 700 is switched from an open state to a closed state.

[0059] Specifically, when the water inlet valve 700 switches from an open state to a closed state, the water flow in the pipe on the water inlet side of the water inlet valve 700 is suddenly cut off. However, the water flow still has the inertia to continue flowing forward, generating a large impact force at the water inlet end of the water inlet valve 700, causing the water inlet pipe and the water inlet valve 700 to vibrate and generate noise. This is the water hammer effect. In real life and production, the effects of the water hammer effect are often harmful side effects. The present invention fully utilizes the impact force of the water hammer effect by connecting the water hammer suppression device 640 in parallel between the water inlet and outlet of the water inlet valve 700. When the water inlet valve 700 switches from an open state to a closed state, the water flow at the water outlet of the water inlet valve 700 is pushed forward, preventing the accumulation of water in the water inlet pipe after the water inlet valve 700 is closed, thereby preventing scale deposition.

[0060] In some embodiments, the water hammer suppression device 640 includes a cylinder assembly 641, one end of which is connected to the water inlet main 610 via a drain pipe 644, and the other end of which is connected to the water inlet main 610 via an exhaust pipe 645. The cylinder assembly 641 is provided with a piston assembly 642 that reciprocates along the direction of water flow in the water inlet main 610. An elastic member 643 is sandwiched between the piston assembly 642 and the end of the cylinder assembly 641. The elastic member 643 is configured to have an elastic force that absorbs the impact force of the water flow. It should be noted that the piston assembly 642 is sealed to the cylinder wall. Furthermore, through extensive experimental research, technicians have determined the relative relationship between the impact force and elastic force of the water hammer effect, thereby selecting an appropriate elastic member to avoid the situation where the impact force of the water hammer cannot overcome the elastic force of the elastic member at low water pressures.

[0061] Figure 2 and Figure 3 The water inlet valve 700 is shown in the normally closed or normally open state. Figure 1 A partial enlarged schematic diagram of the structure at A in FIG and the water inlet valve 700 when it switches from the open state to the closed state Figure 1 A partial enlarged schematic diagram of the structure at A in FIG. Figure 2 and Figure 3 The working principle of the water hammer suppression device 640 is introduced in detail.

[0062] like Figure 2 As shown, when the water inlet valve 700 is in the closed state, the water pressure in the water inlet pipe is stable, and the elastic force of the elastic member 643 is sufficient to overcome the water pressure on the right side of the water inlet valve 700, so that the piston assembly 642 is at the end of the cylinder assembly 641 close to the water inlet of the water inlet valve 700 ( Figure 2The right end is shown in the figure). When the water inlet valve 700 is switched from the closed state to the open state, the water pressure at the position of the water inlet of the water inlet valve 700 in the water inlet pipe decreases, and the piston assembly 642 is still maintained in the cylinder assembly 641 at the end close to the water inlet of the water inlet valve 700. When the water inlet valve 700 is switched from the open state to the closed state, since the water flow in the water inlet pipe at the water inlet of the water inlet valve 700 is suddenly cut off, the water flow still has the inertia to continue to flow forward, which will generate a large impact force at the water inlet of the water inlet valve 700. This impact force prompts the water flow to enter the cylinder assembly 641 through the drain pipe 644, thereby overcoming the elastic force of the elastic member 643 and pushing the piston assembly 642 in the cylinder assembly 641 toward the water outlet ( Figure 2 (shown at the left end in FIG), under the action of piston assembly 642, the gas originally stored in cylinder assembly 641 is discharged from cylinder assembly 641 through exhaust pipe 645. The discharged gas acts on the water flow at the outlet of water inlet valve 700, causing the water flow there to flow forward rapidly. When the water hammer effect ends, the water pressure on the right side of water inlet valve 700 returns to balance, and elastic member 643 pushes piston assembly 642 to move right. Figure 2 When the piston assembly 642 moves to the right, it will draw air from the water inlet pipe, which is no longer filled with water, into the cylinder assembly 641, thereby generating an airflow in the water inlet pipe in the opposite direction of the water flow, completely removing the water film at the outlet of the water inlet pipe and avoiding scale deposition.

[0063] In some embodiments, the outlet direction of the exhaust pipe 645 is aligned with the water inlet direction of the water inlet main 610. Thus, when water flows through the outlet of the exhaust pipe 645, negative pressure is generated there, and the water does not flow back through the exhaust pipe 645 into the interior of the cylinder assembly 641.

[0064] In some embodiments, the cylinder assembly 641 includes a first cylinder 6411 and a second cylinder 6412 connected to each other, wherein the diameter of the first cylinder 6411 is smaller than that of the second cylinder 6412. The first cylinder 6411 is connected to the drain pipe 644, and the second cylinder 6412 is connected to the exhaust pipe 645. The piston assembly 642 includes a first piston 6421 and a second piston 6422. The first piston 6421 is configured to reciprocate within the first cylinder 6411, and the second piston 6422 is configured to reciprocate within the second cylinder 6412. The first piston 6421 and the second piston 6422 are connected by a rigid connector 6423. An elastic member 643 is interposed between the second piston 6422 and the end of the second cylinder 6412. The elastic member 643 is configured to exert an elastic force that causes the second piston 6422 to approach the first cylinder 6411.

[0065] In the above scheme, by setting the cylinder assembly 641 and the piston assembly 642 as a two-stage structure, when the water pressure in the water inlet pipe is low, the impact force generated by the water flow at the water inlet of the water inlet valve 700 can still be used to push the water flow at the water outlet of the water inlet valve 700 to flow forward.

[0066] Specifically, because the first piston 6421 and the second piston 6422 are connected by a rigid connector 6423, and the larger diameter of the second cylinder 6412 allows for a larger volume of gas, the impact of the water flow can propel the first and second pistons 6421 and 6422 to move synchronously, with both moving the same distance. This allows the second piston 6422 to expel more air using only a small amount of water. It should be noted that only gas exists within the second cylinder 6412, while either air or water can exist within the first cylinder 6411. Therefore, to reduce the overall resistance to movement of the piston assembly 642, a clearance fit between the second piston 6422 and the second cylinder 6412 is sufficient.

[0067] In some embodiments, the diameter of the drain pipe 644 is smaller than the diameter of the exhaust pipe 645 , so as to increase the exhaust speed and fully utilize the water hammer effect.

[0068] Preferably, an air vent is provided on the first cylinder 6411 near the second cylinder 6412 to prevent negative pressure from being generated between the first piston 6421 and the second piston 6422 when the piston assembly 642 moves to the left, thereby increasing the movement resistance of the piston assembly 642.

[0069] In some embodiments, as Figure 4 As shown, the outlet of the main section 621 of the first water inlet branch pipe 620 is connected to a bubbler 650, which includes a jet pipe 651 and a bubbler pipe 652. The jet pipe 651 is connected to the outlet of the main section 621 of the first water inlet branch pipe 620. The diameter of the jet pipe 651 matches the diameter of the first water inlet branch pipe 620. The jet pipe 651 is equipped with a jet nozzle 6512 that gradually narrows along the water outlet direction. The jet nozzle 6512 is used to increase the solubility of gas in water and the water flow rate. The bubbler pipe 652 is connected to the jet pipe 651 and is equipped with a filter 6524. The filter 6524 is used to precipitate dissolved gas in the water to form microbubble water.

[0070] It should be noted that the axial direction of the bubbler 650 is tilted downward, so a connecting elbow is provided between the outlet of the main pipe section 621 of the first water inlet branch pipe 620 and the bubbler 650 .

[0071] Figure 5FIG. 6 shows the internal structure of the jet tube 651 and the bubble tube 652 according to an exemplary embodiment of the present invention. Figure 5 As shown, as water flows through the jet nozzle 6512 in the jet tube 651, it compresses the water and increases its pressure. This pressure also further increases the gas solubility in the water, thereby increasing the amount of air dissolved in the water. After the water is compressed by the jet tube 651, its outflow velocity increases. After passing through the filter 6524 in the bubble tube 652, the water is blocked at multiple points. The pressure drops dramatically after the blockage points, allowing the dissolved gas in the water to be released as bubbles, thus forming microbubble water.

[0072] In detail, after the water flows through the obstacle, the pressure behind the obstacle decreases, and the gas dissolved in the water will quickly overflow. Due to the surface tension of the water molecules, the water molecules surround the gas, forming bubbles. In other words, the lower the pressure behind the obstacle is compared to the pressure before the obstacle, the more bubbles will overflow. In addition, the more gas dissolved in water, the more precipitation will occur, and the higher the pressure, the easier it is for the gas to dissolve in water. Therefore, the present invention applies pressure through the jet tube 651 to allow more gas to dissolve in water. The flow rate of the pressurized water becomes faster. After encountering the filter screen 6524 in the bubble tube 652, the pressure difference on both sides of the filter screen 6524 in the flow direction of the water flow is larger, making it easier for the gas to overflow and generate bubble water.

[0073] However, due to the smaller mesh size of the filter 6524 within the bubble tube 652, the surface tension of water molecules is stronger. The presence of the filter 6524 also makes it easier for a water film to form at the outlet of the first water inlet main pipe 610, hindering air circulation and increasing the likelihood of scale deposits. In the present invention, when the water inlet valve 700 is closed, the outlet of the second water inlet branch pipe 630 is open to the atmosphere. Therefore, the water in the first water inlet branch pipe 620 is not constrained by negative pressure. Under the influence of the airflow generated by the water hammer effect, the remaining water flows out more quickly and does not accumulate, thus preventing scale deposits and affecting the subsequent production of microbubble water. Otherwise, when the water inlet valve 700 is closed and water stops flowing in, since the rear end of the water inlet main pipe 610 is closed, negative pressure will be generated at the rear when the water in the water inlet main pipe 610 flows forward again, so that the water flowing forward is restrained and cannot continue to flow forward. Due to the surface tension of water molecules and the small diameter of the water pipe, it is difficult for air to enter from the bubble tube 652 at the end of the first water inlet branch pipe 620 to relieve the negative pressure. Therefore, the water accumulated inside cannot be discharged.

[0074] In some embodiments, as Figure 5As shown, the jet nozzle 6512 can be manufactured integrally with the jet tube 651. The jet nozzle 6512 is a nozzle with a smooth transition and gradually narrowing, which can pressurize and speed up the water flowing through it. The pressurization process can increase the solubility of gas in water. The higher the solubility of air in water, the easier it is to generate bubbles and produce more bubble water. After the accelerated water flow encounters a mesh obstruction structure such as a filter 6524, the pressure drops sharply, which can precipitate more air and produce more bubbles. Both ends of the jet tube 651 are provided with a second threaded section 6511 or other connection limiting structure, such as a rib or groove, which is detachably connected to the main section 621 of the first water inlet branch pipe 620.

[0075] In some embodiments, the filter 6524 is tilted within the bubble tube 652. For example, the angle α between the filter 6524 and the water flow direction of the bubble tube 652 ranges from 5° to 60°. Preferably, α ranges from 10° to 40°. Because the filter 6524 is tilted, the area of ​​the liquid sprayed onto the filter 6524 is increased, thereby generating more bubbles.

[0076] In some embodiments, the inner wall of the bubble tube 652 is circumferentially provided with a step groove 6521 that is elliptical when viewed from its vertical direction, and the filter screen 6524 is obliquely clamped on the step groove 6521; the jet tube 651 is inserted into the bubble tube 652, and a limiter 6526 is embedded between the end of the jet tube 651 and the filter screen 6524.

[0077] Specifically, the bubble tube 652 is a straight tube with an inclined stepped groove 6521 on its inner wall for retaining the elliptical filter 6524. A retaining member 6526 is also located within the stepped groove 6521 for securing the filter 6524. For example, the retaining member 6526 is a tube having a standard hollow cylinder at the top and an inclined surface cut off at the bottom to create an elliptical cross-section.

[0078] The inner diameter of the limiter 6526 matches the maximum inner diameter of the jet tube 651 and the minimum inner diameter of the bubble tube 652, so that there is no additional obstruction to the water flow. At the same time, a first threaded section 6522 or other pipeline connection structure, such as a rib, a groove, a buckle and other structures, is provided on the top of the bubble tube 652 for detachable connection with the jet tube 651. The bubble tube 652 should match the connection structure of the jet tube 651. After the jet tube 651 and the bubble tube 652 are installed, the jet tube 651 presses tightly against the limiter 6526, indirectly fixing the filter screen 6524; the filter screen 6524 is installed at a larger angle, which can prevent the mud and sand particles from clogging and adhering to the filter screen 6524, and can guide the mud and sand particles to move to the lower angle.

[0079] Optionally, the filter screen 6524 is provided with a sand discharge hole 6525 at a downstream position along the water flow direction, which can discharge the sediment collected there after being filtered by the filter screen 6524. In addition, the filter screen 6524 is tilted to increase the water flow area and generate more bubbles.

[0080] In addition, the present invention stipulates that the jet tube 651 is detachably connected to the first water inlet branch 620, and the bubble tube 652 is detachably connected to the jet tube 651. Therefore, even if larger particles of mud and sand accumulate on the jet nozzle 6512 or the filter screen 6524, it is convenient to disassemble the various components of the water inlet assembly 600 for cleaning or replacement.

[0081] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
