Description

CROSS-REFERENCE TO RELATED APPLICATIONS



[0001] The present application claims priority from the following Chinese patent applications for invention: Chinese invention patent application No. 202210470624.4 filed on April 28, 2022, and Chinese invention patent application No. 202210471298.9 filed on April 28, 2022, the entire disclosures of which are both incorporated herein by reference.

FIELD OF THE INVENTION



[0002] The present disclosure relates to the technical field of washing apparatus, and specifically to a water inflow system and control method for a washing apparatus, as well as a washing apparatus.

BACKGROUND OF THE INVENTION



[0003] Micro-bubbles usually refer to tiny bubbles with a diameter below 50 microns (µm) when bubbles are generated. Micro-bubbles can also be divided into micro/nano-bubbles, micron-bubbles, or nano-bubbles based on their diameter range. Micro-bubbles stay in liquid for a longer time due to their low buoyancy in liquid. At the same time, when in liquid, micro-bubbles will contract under the action of water pressure until they finally break, generating smaller nano-bubbles. During this process, the bubbles become smaller, resulting in a slower ascending speed and higher melting efficiency. When micro-bubbles break, they generate high-pressure and high-temperature heat locally, which can destroy foreign objects such as organic matters floating in liquid or attached to objects. In addition, the contraction process of micro-bubbles is accompanied by an increase in negative charge, and a peak state of negative charge usually occurs when the diameter of micro-bubbles is between 1-30 microns. These negative charges have a high oxidation-reduction effect and can effectively decompose pollutants in water. These characteristics enable micro-bubbles to have strong cleaning and purification capabilities. At present, micro-bubbles have been widely used in washing apparatuses such as washing machines.

[0004] In order to improve the washing effect, in existing washing apparatuses, micro-bubbles are generated in the washing water by using various micro-bubble generation devices. However, it is difficult for water inflow pipelines in existing washing apparatuses to ensure sufficient gas supply, which in turn cannot ensure the generation of sufficient micro-bubbles in the fluid.

[0005] Accordingly, there is a need in the art for a new technical solution to solve the above problems.

SUMMARY OF THE INVENTION


First group of solutions



[0006] In order to solve the above problem in the prior art, that is, to solve the technical problem that it is impossible for the water inflow pipelines in the prior art to ensure sufficient gas supply, the present disclosure provides a water inflow system for a washing apparatus, in which the water inflow system includes: a first branch, on which a water controller for controlling on/off of the first branch is provided; a second branch, which is connected in parallel with the first branch, and on which an inflation controller communicated with the atmosphere is provided; a converging pipeline, an upstream end of which is communicated with a downstream end of the first branch and a downstream end of the second branch respectively; and a micro-bubble nozzle, which is communicated with a downstream end of the converging pipeline.

[0007] In the water inflow system for the washing apparatus of the present disclosure, the first branch is connected in parallel with the second branch; water from the first branch and gas from the second branch respectively reach the converging pipeline and then flow together to the micro-bubble nozzle, so that a large number of micro-bubbles are generated through a micro-bubble generation mesh, which are then sprayed toward outer and/or inner cylinders of the washing apparatus. Adding a branch for introducing gas in the water inflow system can ensure sufficient gas supply, improve the degree of gas-water mixing, and generate sufficient micro-bubbles in the water through the micro-bubble nozzle to achieve better washing effect.

[0008] In a preferred technical solution of the water inflow system for the washing apparatus described above, the water inflow system further includes a third branch, which is connected in parallel with both the first branch and the second branch; an upstream end of the third branch is connected to a treatment agent box, and a downstream end of the third branch is communicated with the converging pipeline; and a dispenser is provided on the third branch for pumping a treatment agent from the treatment agent box into the third branch. Through the above arrangement, the treatment agent can reach the micro-bubble nozzle together with water and gas, and a mixed fluid containing a large number of micro-bubbles is formed through the micro-bubble generation mesh, which improves the activity of the treatment agent and enhances the clothing treatment effect.

[0009] In a preferred technical solution of the water inflow system for the washing apparatus described above, a one-way valve is provided on the second branch, and the one-way valve is arranged downstream of the second controller. Through the above arrangement, water or treatment agent can be prevented from entering the second branch and flowing into a housing of the washing apparatus through an air pump.

[0010] In a preferred technical solution of the water inflow system for the washing apparatus described above, the micro-bubble nozzle includes a micro-bubble generation mesh and a nozzle body; the nozzle body has an inlet end, an outlet end, and a cavity extending between the inlet end and the outlet end along a length direction of the nozzle body and having a constant diameter; and the micro-bubble generation mesh covers an end face of the outlet end. Through the above arrangement, the nozzle body of the micro-bubble nozzle of the present disclosure can allow fluid to pass through it and flow toward the micro-bubble generation mesh to form a micro-bubble fluid containing a large number of micro-bubbles, and an interior of the nozzle body has the same inner diameter along its length direction. The structure is simple, and production and manufacturing are easy.

[0011] In a preferred technical solution of the water inflow system for the washing apparatus described above, the micro-bubble nozzle further includes a nozzle cap, which includes a pressing part and a connecting part; the pressing part has an annular wall with a central through hole, and a diameter of the central through hole matches the diameter of the cavity to allow fluid from the cavity to be sprayed through the micro-bubble generation mesh from the central through hole; the connecting part extends outward from the annular wall of the pressing part along a centerline of the central through hole and can be fastened to the outlet end to securely clamp the micro-bubble generation mesh between the end face of the outlet end and the annular wall of the pressing part. Through the above arrangement, by fastening the connecting part to the outlet end, the pressing part can be tightly pressed against the end face of the outlet end, thereby firmly clamping the micro-bubble generation mesh between the pressing part and the outlet end. When high-speed fluid impacts the micro-bubble generation mesh, the micro-bubble generation mesh can maintain its own stability and cut the bubbles in the high-speed water flow, promoting efficient generation of micro-bubbles.

[0012] In a preferred technical solution of the water inflow system for the washing apparatus described above, the micro-bubble generation mesh has multiple mesh layers, and a mesh size of each of the mesh layers is any value between 20 and 300 meshes. Through the above arrangement, a micro-bubble generation mesh is formed by overlapping multiple delicate mesh layers together, which can ensure that the micro-bubble generation mesh sufficiently and effectively cuts bubbles in high-speed water flow, thereby ensuring that the fluid contains a large number of micro-bubbles to improve the treatment effect on clothing.

[0013] In a preferred technical solution of the water inflow system for the washing apparatus described above, the water controller is an electromagnetic valve or a water pump, and the inflation controller is an air pump. Through the above arrangement, the electromagnetic valve or water pump can control on/off of water in the pipeline and provide high-speed water flow to the pipeline. The air pump can control the inflation in the pipeline, ensure the gas content in the fluid, and guarantee the formation of high-speed fluid.

[0014] In a preferred technical solution of the water inflow system for the washing apparatus described above, the dispenser is a piston pump or a peristaltic pump. Through the above arrangement, the dispensing of treatment agent in the treatment agent branch can be controlled, and the use of piston pump or peristaltic pump is advantageous for improving the efficiency of pumping treatment agent into the pipeline, and facilitates the adjustment of flow rate of the treatment agent in the pipeline.

[0015] In order to solve the above problem in the prior art, that is, to solve the technical problem that it is impossible for the water inflow pipelines in the prior art to ensure sufficient gas supply, the present disclosure also provides a washing apparatus, which includes the water inflow system according to any one of the preceding items. Through the above arrangement, by adding a second branch for introducing gas in the water inflow system, the washing apparatus of the present disclosure can ensure the gas content in the fluid, optimize the mixing effect of gas and liquid, and further enhance the treatment effect on clothing. In addition, when the third branch communicated with the treatment agent box is provided, the washing apparatus of the present disclosure also enables the treatment agent to be mixed with water and gas, and foam water containing a large number of micro-bubbles is formed through the micro-bubble nozzle to enhance the treatment effect on clothing.

[0016] In a preferred technical solution of the washing apparatus described above, the washing apparatus further includes a treatment agent box having a first accommodation chamber, a second accommodation chamber and a third accommodation chamber, each of which can accommodate a treatment agent, and the water inflow system includes a third branch connected in parallel with both the first branch and the second branch thereof; the first accommodation chamber, the second accommodation chamber and the third accommodation chamber are respectively connected with the third branch. Through the above arrangement, treatment agents with different functions can be placed in the three accommodation chambers arranged in the treatment agent box; for example, a detergent, a softener and a disinfectant are placed in the three accommodation chambers respectively, so as to meet various washing needs and therefore improve the user experience.

[0017] In a preferred technical solution of the washing apparatus described above, the washing apparatus further includes a sealing window gasket, on which a fixed tube is provided, and the micro-bubble nozzle of the water inflow system is detachably inserted into the fixed tube. Through the above arrangement, the micro-bubble nozzle is fixed on the sealing window gasket, so that it can spray a fluid containing a large number of micro-bubbles into a washing chamber of the washing apparatus to treat objects to be cleaned such as the clothing, thereby improving the washing effect of the washing apparatus.

[0024] In a preferred technical solution of the washing apparatus described above, the micro-bubble generation mesh has multiple mesh layers, and a mesh size of each of the mesh layers is any value between 20 and 300 meshes. Through the above arrangement, a micro-bubble generation mesh is formed by overlapping multiple delicate mesh layers together, which can ensure that the micro-bubble generation mesh sufficiently and effectively cuts bubbles in high-speed water flow, thereby ensuring that the fluid contains a large number of micro-bubbles to improve the treatment effect on clothing.

[0025] In order to solve the above problem in the prior art, that is, to solve the technical problem that it is impossible for the water inflow pipelines in the prior art to ensure sufficient gas supply, the present disclosure also provides a control method for a washing apparatus; the washing apparatus is the washing apparatus according to any one of the preceding items, and the control method includes: turning on a water controller to introduce water into a first pipeline; turning on a dispenser to pump a fluid in a second pipeline toward a converging pipeline; making the water from the first pipeline and the fluid from the second pipeline flow into the converging pipeline and form a fluid water therein; making the fluid water from the converging pipeline flow through a micro-bubble nozzle to generate a micro-bubble fluid; and spraying the micro-bubble fluid into a washing chamber.

An outer cylinder 40 and an inner cylinder 30 are provided inside the housing 50. The outer cylinder 40 and the inner cylinder 30 together form a washing chamber of the washing apparatus 1. The inner cylinder 30 is rotatably positioned inside the outer cylinder 40, and is connected to a motor through a transmission shaft and bearings.

[0040] The washing apparatus 1 of the present disclosure also has a treatment agent box 20. The treatment agent box 20 is arranged at the upper left position of the housing 50 of the washing apparatus 1 as shown in the figure. Alternatively, the treatment agent box 20 can also be arranged at the upper right position of the housing 50 as shown in the figure or at other suitable positions. Users can open the treatment agent box 20 from the outside and add clothing treatment agents into the treatment agent box 20. The clothing treatment agents include but are not limited to a detergent, a softener and a disinfectant. The treatment agent box 20 has a first accommodation chamber 21, a second accommodation chamber 22 and a third accommodation chamber 23. The first accommodation chamber 21 is the leftmost compartment inside the treatment agent box 20 as shown in the figure, and is used to accommodate the detergent; the second accommodation chamber 22 is the middle compartment inside the treatment agent box 20 as shown in the figure, and is used to accommodate the softener; and the third accommodation chamber 23 is the rightmost compartment inside the treatment agent box 20 as shown in the figure, and is used to accommodate the disinfectant. In alternative embodiments, the first accommodation chamber 21 can also be designed to accommodate the softener, the disinfectant, or another suitable clothing treatment agent. The second accommodation chamber 22 and the third accommodation chamber 23 can also be designed to accommodate any suitable clothing treatment agent, as long as the placement of the clothing treatment agents in the treatment agent box 20 is reasonable. Alternatively, the treatment agent box 20 can also be provided with two accommodation chambers or other suitable number of accommodation chambers to accommodate the same or different clothing treatment agents, thereby meeting different washing and care needs.

[0041] As shown in FIG. 1, the washing apparatus 1 of the present disclosure further includes a water inflow system 10. The water inflow system 10 includes a first branch 11, a second branch 12, a third branch 13, a converging pipeline 14, and a micro-bubble nozzle 15. The first branch 11, the second branch 12 and the third branch 13 are all connected in parallel with each other, and downstream ends of the first branch 11, the second branch 12 and the third branch 13 are all in fluid communication with an upstream end of the converging pipeline 14. The first branch 11 is a water inflow branch, and its upstream end can be directly connected to a joint of external water source, such as a faucet. A water controller 111 is provided on the first branch 11 for controlling on/off of water flow in the first branch 11. The water controller 111 is a water pump that can pump water flow into the first branch 11 at high pressure. In alternative embodiments, the water controller 111 may also be an electromagnetic valve or another suitable controller. The second branch 12 is a branch for introducing gas, on which an inflation controller 121 and a one-way valve 122 are provided. The inflation controller 121 is an air pump that can pump air into the second branch 12 at high pressure. Alternatively, the inflation controller 121 may also be a breather valve or another suitable controller. The one-way valve 122 is arranged downstream of the inflation controller 121, and it can prevent the water in the first branch 11 and the treatment agent in the third branch 13 from flowing into the second branch 12 and into the housing of the washing apparatus 1 through the air pump. The third branch 13 is a treatment agent branch. An upstream end of the third branch 13 is connected to the treatment agent box 20, and the third branch 13 is connected to the first accommodation chamber 21, the second accommodation chamber 22 and the third accommodation chamber 23 of the treatment agent box 20 respectively. A dispenser 131 is provided on the third branch 13. The dispenser 131 is a piston pump and can pump the clothing treatment agents in the treatment agent box 20 into the third branch 13. Alternatively, the dispenser 131 can also be a peristaltic pump.

[0042] As shown in FIG. 1, the upstream end of the converging pipeline 14 is connected to the downstream ends of the first branch 11, the second branch 12 and the third branch 13 respectively, and its downstream end is connected to the micro-bubble nozzle 15. The fluids introduced into the converging pipeline 14 from each branch can be sprayed into the inner cylinder 30 and/or the outer cylinder 40 of the washing apparatus 1 through the micro-bubble nozzle 15. When the washing apparatus 1 needs to use the clothing treatment agent to treat the clothing, the water controller 111 is turned on to introduce water flow into the first branch 11 and make it flow at high speed toward the converging pipeline 14. At the same time, the dispenser 131 pumps the corresponding clothing treatment agent from the treatment agent box 20, pumps the clothing treatment agent into the third branch 13, and makes it flow into the converging pipeline 14. The inflation controller 121 is also turned on at the same time, so that it pumps gas into the second branch 12 at high pressure and makes the gas flow toward the converging pipeline 14. The water, treatment agent and air coming from the three branches respectively are mixed in the converging pipeline 14 to form a mixed fluid, which flows at high speed toward the micro-bubble nozzle 15 at the downstream end of the converging pipeline 14. After the mixed fluid passes through the micro-bubble nozzle 15, foam water containing a large number of micro-bubbles is formed and sprayed onto the clothing to be treated in the inner cylinder 30 of the washing apparatus 1. When the washing apparatus 1 needs to use micro-bubble water to rinse the clothing, the water controller 111 is turned on to introduce water flow into the first branch 11 and make it flow at high speed toward the converging pipeline 14. At the same time, the inflation controller 121 is also turned on, so that it pumps gas into the second branch 12 at high pressure and makes the gas flow toward the converging pipeline 14. After the water from the first branch 11 and the air from the second branch 12 are mixed in the converging pipeline 14, they flow at high speed toward the micro-bubble nozzle 15, forming bubble water containing a large number of micro-bubbles, which is sprayed by the micro-bubble nozzle 15 onto the clothing to be rinsed in the inner cylinder 30 of the washing apparatus 1.

[0043] As shown in FIG. 1, the micro-bubble nozzle 15 is detachably fixed on a top part of the sealing window gasket 53 as shown in the figure, and is fixedly connected with the sealing window gasket 53. Alternatively, the micro-bubble nozzle 15 can also be fixed on a side part or upper part of the sealing window gasket 53 as shown in the figure. In alternative embodiments, the micro-bubble nozzle 15 can also be fixedly connected with the outer cylinder 40, or fixedly connected with both the outer cylinder 40 and the sealing window gasket 53. In one or more embodiments, a fixed tube (not shown in the figure) is provided on the sealing window gasket 53. The fixed tube extends outward in a radial direction of the sealing window gasket 53 and has a diameter that matches the size of the micro-bubble nozzle 15. In one or more embodiments, a positioning groove (not shown in the figure) is provided on an inner tube wall of the fixed tube, and a positioning column 154 (see FIG. 2) that matches the positioning groove is provided on the micro-bubble nozzle 15. By inserting the micro-bubble nozzle 15 into the fixed tube of the sealing window gasket 53 and tightly fitting the positioning column 154 on the micro-bubble nozzle 15 with the positioning groove on the sealing window gasket 53, pre-positioning between the micro-bubble nozzle 15 and the sealing window gasket 53 can be achieved. In alternative embodiments, a positioning groove can also be provided on the micro-bubble nozzle 15, and a corresponding positioning column can be provided on the sealing window gasket 53 to achieve pre-positioning between the micro-bubble nozzle 15 and the sealing window gasket 53. After completing the pre-positioning of the micro-bubble nozzle 15, a fixed installation part 155 (see FIG. 2) of the micro-bubble nozzle 15 is fixed together with the sealing window gasket 53 by screws. In alternative embodiments, the micro-bubble nozzle 15 can also be fixedly connected to the sealing window gasket 53 and/or the outer cylinder 40 through a snap-fit structure or other suitable connection means.

[0044] FIG. 2 is a schematic structural view of an embodiment of the micro-bubble nozzle in the water inflow system for the washing apparatus of the present disclosure. FIG. 3 is a schematic cross-sectional view of an embodiment of the micro-bubble nozzle of the present disclosure taken along section line A-A in FIG. 2. As shown in FIGS. 2 and 3, in one or more embodiments, the micro-bubble nozzle 15 includes a micro-bubble generation mesh 151, a nozzle body 152, and a nozzle cap 153.

[0045] The nozzle body 152 has an inlet end 521 and an outlet end 522. As shown in FIG. 2, on the outside of the nozzle body 152, the micro-bubble nozzle 15 also has a positioning column 154, a fixed installation part 155, and an anti-falling part 156. The anti-falling part 156 is arranged at the end of the inlet end 521 of the nozzle body 152 and protrudes radially outward around an outer wall of the inlet end 521. In alternative embodiments, the anti-falling part 156 can also be an annular groove structure recessed inward from the outer wall of the inlet end 521, as long as it can prevent the micro-bubble nozzle 15 from falling off the downstream end of the converging pipeline 14. The positioning column 154 is a long rib structure located in the middle of the nozzle body 152, which protrudes radially outward from the outer wall of the nozzle body 152 and extends in the length direction of the nozzle body 152. The fixed installation part 155 has a first fixed installation part 155a and a second fixed installation part 155b symmetrically positioned on the outer wall of the nozzle body 152. The first fixed installation part 155a and the second fixed installation part 155b are respectively arranged on both sides of the positioning column 154. Alternatively, only the first fixed installation part 155a or only the second fixed installation part 155b is arranged on the outer wall of the nozzle body 152. Threaded holes 1551 are provided on both the first fixed installation part 155a and the second fixed installation part 155b to fix the micro-bubble nozzle 15 to a target position on the washing apparatus 1 by screws. Alternatively, the fixed installation part 155 can also be a snap-fit structure or any other suitable connection structure.

[0046] As shown in FIG. 3, the nozzle body 152 has a cavity 523 therein. The cavity 523 has the same diameter along the length direction of the nozzle body 152 (i.e., the inner diameter of the nozzle body 152). The micro-bubble generation mesh 151 covers an end face of the outlet end 522 of the nozzle body 152, and is fixed to the end face. When the fluid from the converging pipeline 14 rushes toward the micro-bubble generation mesh 151 at high speed, the micro-bubble generation mesh 151 can cut the bubbles in the fluid to form a large number of micro-bubbles in the fluid. In one or more embodiments, the micro-bubble generation mesh 151 includes four mesh layers. The pore density of each mesh layer is 120 meshes, and each mesh layer is made of polyester fiber material. The four mesh layers are overlapped together to form the micro-bubble generation mesh 151. In alternative embodiments, the pore density of the mesh layer can also be any value between 20 and 300 meshes. Alternatively, the mesh layer can also be made of any other suitable high polymer material (such as cotton fiber, polypropylene fiber, etc.), or made of metal material (such as stainless steel wire, nickel wire, etc.). In alternative embodiments, the number of mesh layers in the micro-bubble generation mesh 151 can be any other value; preferably, the number of mesh layers is 1 to 10. An external thread 524 of the outlet end is also provided at a lower part of the nozzle body 152 at a position near the outlet end 522, so that the nozzle body 152 can be fixed together with the nozzle cap 153 through threaded connection.

[0047] As shown in FIG. 3, the nozzle cap 153 includes a pressing part 531 and a connecting part 532. The pressing part 531 has an annular wall 5311 with a central through hole (i.e., a through hole 533 of the nozzle cap). An inner diameter of the through hole 533 of the nozzle cap matches the diameter of the cavity 523, that is, they are the same as each other, thus allowing the fluid from the cavity 523 to pass through the micro-bubble generation mesh 151 and then be sprayed from the through hole 533 of the nozzle cap without being hindered. In alternative embodiments, the inner diameter of the through hole 533 of the nozzle cap may be slightly smaller than the inner diameter of the cavity 523, so as to more securely fix the micro-bubble generation mesh 151 between the outlet end 522 and the nozzle cap 153. The connecting part 532 extends from the annular wall 5311 of the pressing part 531 along a centerline of the cavity 523 toward the inlet end 521. An inner diameter of the connecting part 532 is slightly larger than the outer diameter of the outlet end 522, so that the connecting part 532 can wrap around the outlet end 522. An internal thread 5321 of the connecting part is provided on an inner peripheral wall of the connecting part 532. The internal thread 5321 of the connecting part matches the external thread 524 of the outlet end of the nozzle body 152 to fix the nozzle cap 153 on the nozzle body 152. In alternative embodiments, the nozzle cap 153 and the nozzle body 152 can also be connected through snap-fit, or through other suitable fastening methods. When the nozzle cap 153 is securely connected to the nozzle body 152 through the connecting part 532, the micro-bubble generation mesh 151 is firmly clamped between the outlet end 522 and the annular wall 5311 of the pressing part 531. At this time, the through hole 533 of the nozzle cap is in center-alignment with the cavity 523, the fluid from the converging pipeline 14 can sequentially pass through the cavity 523, the micro-bubble generation mesh 151 and the through hole 533 of the nozzle cap, and finally is sprayed onto the clothing in the inner cylinder 30 of the washing apparatus 1.

[0048] In alternative embodiments, the nozzle may be any known suitable nozzle structure. For example, different Venturi structures are provided inside the nozzle body of the nozzle to create a negative pressure environment inside the nozzle body, which can draw in gas from the outside and increase the mixing degree of fluid and gas.

As shown in FIG. 7, in one or more embodiments, when the control method for the washing apparatus 1 of the present disclosure starts, step S1 is first executed, that is, the water controller 111 is turned on to introduce water into the first pipeline 11. The duration in which the water controller 111 is turned on depends on the washing needs, such as a suitable time period of 2 minutes or 5 minutes, etc. At the same time or next, step S2 is executed, that is, the dispenser 121 is turned on to pump the fluid in the second pipeline 12 toward the converging pipeline 13. Next, step S3 is executed, that is, water from the first pipeline 11 and fluid from the second pipeline 12 flow into the converging pipeline 13 and form a fluid water therein. Then, step S4 is executed, that is, the fluid water from the converging pipeline 13 flows through the micro-bubble nozzle 14 to generate a micro-bubble fluid. Finally, step S5 is executed, that is, the micro-bubble fluid is sprayed into the washing chamber, namely, the micro-bubble fluid is sprayed into the inner cylinder 30 and/or the outer cylinder 40. After completing step S5, the control method ends.
