Description

Technical Field

[0001] The invention belongs to the field of washing machines, and in particular relates to a water filling box and a washing machine. Background Art

[0002] The water injection box is an important component of the washing machine. Before the washing machine is filled with water, detergents such as washing powder can be added to the delivery chamber of the dispenser box below the water injection box. Then, after the washing machine is filled with water, water flows through the water injection box, flushing the detergents such as washing powder in the delivery chamber of the dispenser box to quickly dissolve the detergents, and the detergents flow into the washing machine barrel with the water flow to achieve a spraying effect.

[0003] In daily life, due to the influence of factors such as terrain and floor, the water supply pressure obtained by users is often not constant. When the water pressure of the existing washing machine water filling box structure is insufficient, the water flow rate is slow and easily interrupted, and the ideal spray effect cannot be achieved. The residues of detergents such as washing powder cannot be rinsed away, affecting the user experience.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The present invention provides a water filling box capable of stabilizing the water supply pressure, which can achieve pressure division for the water flow in the water inlet chamber when the water supply pressure is high, and pressure boosting for the water flow in the water inlet chamber when the water supply pressure is insufficient, thereby ensuring that the water filling box can achieve an effective spraying effect under different water pressures, and at the same time can also completely rinse off the detergent residues in the dispenser box delivery chamber, thereby improving the user experience of the product.

[0006] Another object of the present invention is to provide a washing machine having the water filling box.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] In one aspect, the present invention provides a water filling box, comprising:

[0009] a water inlet chamber, wherein the water inlet chamber has a water inlet for injecting water into the water inlet chamber;

[0010] At least two water diversion chambers are connected with the water inlet chamber through the water outlet. The water diversion chamber is provided with a water outlet. The water outlet of at least one water diversion chamber is provided with a one-way valve for controlling the opening and closing of the water outlet.

[0011] Furthermore, the water outlets of at least two water diversion chambers are provided with one-way valves.

[0012] Furthermore, the one-way valves provided at the water outlets of at least two water-dividing chambers have different opening pressures.

[0013] Furthermore, the one-way valve comprises a valve plug and an elastic member that provides a restoring force for the valve plug to close the water opening, and the elastic coefficients of the elastic members of each one-way valve are different.

[0014] Furthermore, the water injection box comprises two water diversion chambers, namely a first water diversion chamber and a second water diversion chamber, and the total water output of the water outlet hole of the first water diversion chamber is less than the water inflow of the water inflow chamber;

[0015] Preferably, the first water diversion chamber is connected to the water inlet chamber through a first water opening, and the water flow rate of the first water opening is smaller than the water flow rate of the water inlet chamber.

[0016] Since the total water output of the water outlet of the first water diversion chamber is less than the water inlet of the water inlet chamber, the water pressure in the water inlet chamber is always greater than the water pressure of the first water diversion chamber. When the water supply pressure is insufficient, the water in the water inlet chamber can easily squeeze into the first water diversion chamber by relying on its own water flow pressure, so as to increase the water pressure of the water inlet chamber. Preferably, the water flow of the first water outlet is less than the water inlet of the water inlet chamber, so as to further increase the water pressure of the water inlet chamber.

[0017] Furthermore, the second water diversion chamber is connected to the water inlet chamber through a second water opening, the second water opening is provided with a second one-way valve, and the total water output of the first water diversion chamber water outlet hole and the second water diversion chamber water outlet hole is greater than the water inlet of the water inlet chamber.

[0018] Since the total water output of the first water diversion chamber outlet hole and the second water diversion chamber outlet hole is greater than the water inlet volume of the water inlet chamber, the first water diversion chamber and the second water diversion chamber can easily divide the pressure of the water flow in the water inlet chamber.

[0019] Furthermore, the sum of the water flow rate of the first water opening and the water flow rate of the second water opening is greater than the water inlet rate of the water inlet chamber.

[0020] Furthermore, the first water outlet is provided with a first one-way valve, and the opening pressure of the second one-way valve is greater than the opening pressure of the first one-way valve.

[0021] Furthermore, the first water diversion chamber is arranged at the center of the water injection box, adjacent to the water inlet chamber, and the second water diversion chamber is a "C"-shaped structure, partially surrounded by the outside of the first water diversion chamber.

[0022] Another aspect of the present invention provides a washing machine having the water filling box.

[0023] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0024] The present invention provides a water filling box and a washing machine capable of stabilizing the water supply pressure. When the water supply pressure is high, the water flow in the water inlet chamber can be pressurized, and when the water supply pressure is insufficient, the water flow in the water inlet chamber can be pressurized, thereby ensuring that the water filling box can achieve an effective spraying effect under different water pressures. At the same time, the detergent residue in the dispenser box can be completely rinsed off, thereby improving the user experience of the product.

[0035] Figure 1 This is a structural schematic diagram of the water filling box of the present invention. The water filling box 1 includes: a water inlet chamber 10, a first water diversion chamber 21 and a second water diversion chamber 22. The water inlet chamber 10 has a water inlet 11 for injecting water into the water inlet chamber 10; the first water diversion chamber 21 is connected to the water inlet chamber 10 through a first water opening 231, and the second water diversion chamber 22 is connected to the water inlet chamber 10 through a second water opening 232. The second water opening 232 is provided with a second one-way valve 25.

[0036] Figure 2 This is another structural schematic diagram of the water filling box of the present invention. The water filling box 1 includes: a water inlet chamber 10, a first water diversion chamber 21 and a second water diversion chamber 22. The water inlet chamber 10 has a water inlet 11 for filling water into the water inlet chamber 10; the first water diversion chamber 21 is connected to the water inlet chamber 10 through a first water through port 231, and the first water through port 231 is provided with a first one-way valve 24; the second water diversion chamber 22 is connected to the water inlet chamber 10 through a second water through port 232, and the second water through port 232 is provided with a second one-way valve 25.

[0037] exist Figure 1 and Figure 2Based on this, technical personnel in this field should be able to conceive of a water injection box structure with three or more water diversion chambers, for example: three, four or more, each water diversion chamber is connected to the water inlet chamber through a water port, and each water port is provided with a one-way valve or some of the water ports are provided with a one-way valve.

[0038] like Figure 1 and Figure 2 As shown, the present invention provides a water filling box 1, comprising: a water inlet chamber 10, the water inlet chamber 10 has a water inlet 11, which is used to fill water into the water inlet chamber 10; it also includes two water diversion chambers 20, which are connected to the water inlet chamber 10 through a water through hole 23, and the water diversion chamber 20 is provided with a water outlet hole 211, and the water through hole 23 of at least one water diversion chamber 20 is provided with a one-way valve for controlling the opening and closing of the water through hole 23.

[0039] As an implementation scheme, Figure 1 As shown, in order to prevent the water flow rate of the water outlet holes 211 in different areas of the water distribution chamber 20 of the water injection box 1 from being affected by the water supply pressure, a water inlet chamber 10, a first water distribution chamber 21 and a second water distribution chamber 22 are arranged inside the water injection box 1, wherein the water inlet chamber 10 has a water inlet 11 for injecting water into the water inlet chamber 10. Two water inlets 11 can be selected to be arranged on the water inlet chamber 10 according to actual water demand, and the water inlets are respectively connected to the first water source and the second water source, and different types of water sources are provided to the water inlet chamber 10 through the first water source and the second water source, and hot water and cold water with different temperatures can also be provided according to different materials of clothes. The first water diversion chamber 21 and the second water diversion chamber 22 are both provided with a water outlet 211. The first water diversion chamber 21 and the second water diversion chamber 22 are connected to the water inlet chamber 10 through the first water port 231 and the second water port 232 respectively. A second one-way valve 25 is provided at the second water port 232 of the second water diversion chamber 22, and the second one-way valve 25 is used to control the opening and closing of the second water port 232. That is, a second one-way valve 25 is arranged in the second water-dividing chamber 22, and a one-way valve is not arranged in the first water-dividing chamber 21. During use, when the water supply pressure is insufficient, after the water inlet chamber is filled, the water pressure of the water flow in the water inlet chamber is directly used to squeeze the water flow into the first water-dividing chamber 21 through the first water opening 231, so as to pressurize the water flow in the water inlet chamber; when the water supply pressure is high, after the water inlet chamber is filled, the water pressure of the water flow in the water inlet chamber is directly used to squeeze the water flow into the first water-dividing chamber 21 for pressure division, and when the first water-dividing chamber 21 cannot completely divide the pressure of the water flow in the water inlet chamber, the water flow in the water inlet chamber squeezes the second one-way valve 25 by its pressure to open the second water opening 232 of the second water-dividing chamber, so as to continue to divide the pressure of the water flow in the water inlet chamber.

[0040] Furthermore, the water outlets 23 of at least two water diversion chambers 20 are provided with one-way valves, and the opening pressures of the one-way valves of at least two water diversion chambers 20 are different. The one-way valves include a valve plug and an elastic member that provides a reset force for the valve plug to close the water outlet, and the elastic coefficients of the elastic members of each one-way valve are different.

[0041] As an implementation scheme, a one-way valve may be provided at the water outlets of the two water diversion chambers, such as Figure 2 As shown, the first water outlet 231 of the first water distribution chamber 21 and the second water outlet 232 of the second water distribution chamber 22 are respectively provided with a first check valve 24 and a second check valve 25, and the opening pressures of the first check valve 24 and the second check valve 25 are different. As stipulated in the national "Water Supply and Drainage Specifications", the water supply pressure of the first floor, i.e., a bungalow, is 0.1MPa, the water supply pressure of the second floor is 0.12Mpa, and the water supply pressure of the third to sixth floors is increased by 0.04Mpa per floor on the basis of the water supply pressure of the second floor. According to national regulations, the pressure of the tap water network reaches 0.14Mpa to be qualified. This means that when the water pressure of the public water supply pipeline cannot meet the needs of users, that is, the water supply above the fourth floor must increase secondary water supply facilities. Therefore, the water pressure on the lower floors will occasionally be higher, and the higher the floor, the more likely it is that the water pressure is insufficient. Therefore, during the water injection process, the water flow in the water inlet chamber 10 can open different one-way valves under different water supply pressures according to the different actual water supply pressures of different floors, so as to flow into different water distribution chambers 20, so as to realize pressurization or pressure division of the water in the water inlet chamber 10 under different water pressures, and ensure that the water flow rate of the water outlet holes 211 in different areas of each water distribution chamber 20 of the water injection box is normal to achieve the spraying effect. In addition, the first one-way valve 24 and the second one-way valve 25 respectively include a first valve plug 241 and a second valve plug 251 and a first elastic member 242 and a second elastic member 252 that provide a reset force for the first valve plug 241 and the second valve plug 251, wherein the elastic coefficients of the first elastic member 242 and the second elastic member 252 are different. Specifically, the first elastic member 242 and the second elastic member 252 can be springs with different elastic coefficients, one end of the spring is fixedly connected to the side wall or bottom wall of the water-dividing chamber, and the other end thereof is retractably suspended and connected to the valve plug, the valve plug is arranged opposite to the water-passing port, and the diameter of the valve plug corresponds to the same diameter of the inner wall of the water-passing port. Due to the different elastic coefficients of the springs, the valve plugs of the one-way valves move to the left along different water-dividing chambers respectively under the combined action of different spring elasticities and water flow impact, so that the water in the water inlet chamber 10 flows into different water-dividing chambers to achieve the purpose of pressurization or pressure division. When the water inlet stops, the spring as an elastic member can return to a free state and close the water-passing port.

[0042] Furthermore, the water filling box 1 includes two water diversion chambers 20, namely a first water diversion chamber 21 and a second water diversion chamber 22, and the total water output of the water outlet hole 211 of the first water diversion chamber is less than the water inlet amount of the water inlet chamber 10; preferably, the first water diversion chamber 21 is connected to the water inlet chamber 10 through the first water port 231, and the water flow rate of the first water port 231 is less than the water inlet amount of the water inlet chamber 10.

[0043] As an implementation scheme, Figure 1 and Figure 2 As shown, a first water inlet 231 for connecting to the water inlet chamber 10 is provided in the first water diversion chamber 21. When the water supply pressure is insufficient, water flows into the water inlet chamber 10 through the water inlet 11 and is stored in the water inlet chamber 10, so that the water inlet chamber 10 is filled with water. Since the total water output of the water outlet 211 of the first water diversion chamber is less than the water output of the water inlet chamber 10, the water pressure in the water inlet chamber is always greater than the water pressure of the first water diversion chamber. At this time, the water inlet chamber relies on its own water flow pressure to squeeze the water flow into the first water diversion chamber to realize the water flow pressurization of the water inlet chamber; as a preferred embodiment, the water flow of the first water inlet is less than the water inlet of the water inlet chamber, which can further pressurize the water flow of the water inlet chamber.

[0044] As another preferred embodiment, the water flow rate of the first water outlet 231 can be set to be less than the water inlet rate of the water inlet chamber 10, and the total water outlet rate of the water outlet holes 211 of the first water diversion chamber 21 can be set to be no more than the water flow rate of the first water outlet 231; or, the water flow rate of the first water outlet 231 can be set to be no more than the water inlet rate of the water inlet chamber 10, and the total water outlet rate of the water outlet holes 211 of the first water diversion chamber 21 can be set to be less than the water flow rate of the first water outlet 231, so that the water in the first water diversion chamber 21 can accumulate to form a certain amount of water flow before flowing out of the water outlet holes 211, which can ensure that the water in the first water diversion chamber can flow out evenly from each water outlet hole 211 to achieve a better spraying effect.

[0045] Further, the second water diversion chamber 22 is connected to the water inlet chamber 10 through the second water opening 232, the second water opening 232 is provided with a second one-way valve 25, and the total water output of the first water diversion chamber water outlet 211 and the second water diversion chamber water outlet 211 is greater than the water inlet of the water inlet chamber 10. The sum of the water flow of the first water opening 231 and the water flow of the second water opening 232 is greater than the water inlet of the water inlet chamber 10.

[0046] As an implementation scheme, Figure 1 and Figure 2As shown, a second one-way valve 25 is provided at the second water outlet 232, and the total water output of the first water-dividing chamber water outlet hole 211 and the second water-dividing chamber water outlet hole 211 is greater than the water inlet volume of the water inlet chamber 10. When the water supply pressure is high, water flows into the water inlet chamber 10 through the water inlet 11 and is stored in the water inlet chamber 10, so that the water inlet chamber 10 is filled with water. Since the total water output of the first water-dividing chamber water outlet hole 211 and the second water-dividing chamber water outlet hole 211 is greater than the water inlet volume of the water inlet chamber 10, the first water-dividing chamber 21 and the second water-dividing chamber 22 can provide pressure-dividing for the water inlet chamber. The sum of the water flow of the first water outlet 231 and the water flow of the second water outlet 232 is greater than the water inlet volume of the water inlet chamber 10, which can further provide pressure-dividing for the water flow of the water inlet chamber.

[0047] Furthermore, the first water port 231 is provided with a first one-way valve 24 , and the opening pressure of the second one-way valve 25 is greater than the opening pressure of the first one-way valve 24 .

[0048] As an implementation scheme, Figure 2 As shown, a first check valve 24 is provided through the first water passage 231, and the opening pressure of the second check valve 25 is greater than the opening pressure of the first check valve 24. When the water supply pressure is insufficient, the water flow in the water inlet chamber can open the first check valve 24, and the opening pressure of the first check valve 24 can be set to be very small. After the water inlet chamber 10 is filled with water, a small amount of water is injected through the water inlet 11 to open the first check valve 24, so that the water flow in the water inlet chamber 10 flows into the first water diversion chamber 21. That is, when the water supply pressure is insufficient, the water flow rate of the water outlet 211 in the first water distribution chamber 21 of the water injection box is guaranteed to be normal, so as to achieve an ideal spraying effect; when the water supply pressure is high, the water flow in the water inlet chamber opens the second one-way valve. Since the opening pressure of the second one-way valve 25 is greater than the opening pressure of the first one-way valve 24, the opening pressures of the two one-way valves are very different. When the water flow in the water inlet chamber squeezes open the second one-way valve, it can also squeeze open the first one-way valve, so that the water in the water inlet chamber flows into the first water distribution chamber 21 and the second water distribution chamber 22 respectively, so as to divide the water flow pressure of the water inlet chamber.

[0049] As an implementation scheme, in order to make the spraying effect of the water outlet of the water-dividing chamber 20 better, multiple water-dividing chambers 20 can also be provided, and the opening pressure of the one-way valve corresponding to each water-dividing chamber is different. Each one-way valve can move to the left along different water-dividing chambers under different water pressures to open different water outlets. Of course, when the water pressure at the water inlet of the water inlet chamber is normal, its water pressure is also much higher than the water pressure when the water pressure is insufficient, and the corresponding one-way valve can also be opened to divide the water pressure of the water inlet chamber.

[0050] As an implementation scheme, a dispenser box is provided below the water injection box 1, the dispenser box includes a delivery chamber, and the water distribution chamber is provided above the delivery chamber. Specifically, washing powder can be delivered in the first water distribution chamber, or a dispenser box can be provided below the water injection box, the dispenser box is provided with a delivery chamber for delivering detergent and softener. When the water pressure is high, the water flow of at least two water distribution chambers can directly rinse the washing powder and other detergents and softeners in the delivery chamber; when the water pressure is insufficient, the water flow of the water inlet chamber is pressurized at the moment of entering the first water distribution chamber due to its pressure, that is, it will generate a strong impact force, which can directly rinse the washing powder in the first water distribution chamber or the detergent residue in the delivery chamber.

[0051] Furthermore, the first water diversion chamber 21 is disposed at the center of the water injection box, adjacent to the water inlet chamber 10 , and the second water diversion chamber 22 is a “C”-shaped structure, partially surrounding the outside of the first water diversion chamber 21 .

[0052] As an implementation scheme, Figure 1 and Figure 2 As shown, the first water diversion chamber 21 is arranged at the center of the water injection box, adjacent to the water inlet chamber 10, and the second water diversion chamber 22 is a "C"-shaped structure, which is partially surrounded by the outside of the first water diversion chamber 21, so that the first water diversion chamber is located in the middle above the delivery chamber. When the water pressure is insufficient, the washing powder and other detergents and softeners in the delivery chamber can be directly flushed, so that the residues can be rinsed more thoroughly.

[0053] Another aspect of the present invention provides a washing machine, which is equipped with the above-mentioned water injection box. The washing machine includes a barrel assembly, which is used to put in and wash clothes; a water inlet valve, which is connected to the water inlet of the water injection box through a water inlet pipe, and is used to control the water inlet flow of the water injection box; a distributor box is also provided below the water injection box, which is used to put in detergents such as washing powder. When the water inlet valve is opened, water flows into the water injection box through the water inlet pipe, and the water flowing out of the water outlet of the water injection box begins to flush the washing powder in the distributor box to dissolve it quickly. The dissolved washing powder flows into the barrel assembly with the water flow to wash the clothes.

[0054] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
