[0001] The invention belongs to the technical field of washing equipment, and specifically provides a water inlet device for washing equipment and the washing equipment. Background Art

[0002] Washing equipment includes washing machines, shoe washing machines, dishwashers, etc., which are generally washed by water, that is, water is required during washing.

[0003] With the continuous progress and development of science and technology, the functionality of washing equipment is developing in an increasingly diverse direction, and some of these functions also need to be realized through water intake. For example, a washing machine with a drying function needs to have water intake to the condenser to condense the drying air when drying. Since different functions have different requirements for water intake flow, in order to achieve the functionality related to water intake, the existing technology generally achieves it by adding water intake pipelines. However, each additional function requires an additional pipeline, which causes the overall structure to become larger in size and increase the cost.

[0004] Taking washing machines as an example, in order to meet the ever-increasing needs of users, existing washing machines generally add a drying function. However, because two different flow rates of water are required when supplying water to the condenser, one is a small flow of continuous water supply to provide condensation water supply, and the other is a large flow of water supply to provide functions such as flushing and drying condenser lint. For this reason, two independent water inlet pipes are added to the washing machine and each water inlet pipe is provided with an independent solenoid valve to achieve water inlet at different flow rates, which makes the water channel structure larger and the manufacturing cost higher.

[0005] Therefore, the art needs a water inlet device for washing equipment and washing equipment to solve the above problems. Summary of the invention

[0009] In a preferred technical solution of the above-mentioned water inlet device, the number of the second control valves and the number of the second water inlet pipelines are both two, and the second control valves correspond to the second water inlet pipelines one by one.

[0010] In the preferred technical solution of the above-mentioned water inlet device, the conduction control valve is a one-way check valve. There are two one-way check valves, which are respectively arranged in the first outlets of the two second control valves to prevent water from entering the second control valve from the first outlet.

[0042] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the following embodiments are explained in conjunction with a washing machine, this is not restrictive. In addition, the technical solution of the present invention is also applicable to other washing equipment, such as a shoe washing machine, a dishwasher or a washer-dryer, etc., and the change of such application objects does not deviate from the principles and scope of the present invention.

[0043] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0044] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Based on the problem of large size and high cost of the water inlet structure of the existing washing machine pointed out in the background technology, the present invention provides a water inlet device for a washing machine and a washing machine, aiming to reduce the size of the water inlet device and reduce the manufacturing cost of the water inlet device.

[0046] Specifically, the washing machine of the present invention comprises a housing, a condenser, a detergent delivery box and a water inlet device arranged in the housing. The water inlet device comprises a body, a first water inlet assembly, a second water inlet assembly, a connecting assembly, a first flow-limiting member and a second flow-limiting member arranged on the body, the first flow-limiting member and the second flow-limiting member are arranged on the first water inlet assembly in sequence along the flow direction of water, and the flow rate of the first flow-limiting member is smaller than the flow rate of the second flow-limiting member, the first water inlet assembly is connected with the condenser, the second water inlet assembly is connected with the detergent delivery box, the connecting assembly comprises a connecting pipeline for connecting the first water inlet assembly and the second water inlet assembly and a conduction control valve for controlling the opening and closing of the connecting pipeline, and the connection point between the first water inlet assembly and the connecting pipeline is located between the first flow-limiting member and the second flow-limiting member.

[0047] When the first water inlet assembly is connected to the external water supply source, the second water inlet assembly is disconnected from the external water supply source and the conduction control valve is closed, water enters the first water inlet assembly, and under the flow limiting effect of the first flow limiting component, the first water inlet assembly supplies water to the condenser at a small flow rate. It should be noted that because the flow rate of the first flow limiting component is smaller than the flow rate of the second flow limiting component, the second flow limiting component does not play a flow limiting role at this time.

[0048] When the first water inlet assembly is disconnected from the external water supply source, and the second water inlet assembly is connected to the external water supply source and the conduction control valve is turned on, water enters the second water inlet assembly and is then divided into two streams, one of which enters the first water inlet assembly through the connecting pipe. Because the connection between the first water inlet assembly and the connecting pipe is located between the first flow limiting component and the second flow limiting component, the water flow no longer flows through the first flow limiting component, but directly flows to the second flow limiting component. Under the flow limiting action of the second flow limiting component, the first water inlet assembly supplies water to the condenser at a large flow rate.

[0049] Through such an arrangement, the first water inlet assembly can achieve water inlet of two flow rates. Compared with the prior art, the water inlet device has a smaller volume and a lower manufacturing cost.

[0050] In addition, by providing the first flow limiting component and the second flow limiting component on the first water inlet assembly, more precise flow control can be achieved, and in actual applications, different types of flow limiting components can be replaced according to different functions, which is convenient and flexible and has a wider range of applications.

[0051] The technical solution of the present invention is described in detail below in conjunction with three specific implementation methods.

[0052] Embodiment 1

[0053] like Figure 1 , Figure 2 and Figure 6As shown, the water inlet device of the present invention comprises a body 7 and a first water inlet assembly 1, a second water inlet assembly 2, a connecting assembly 3, a first flow limiting member 4, a second flow limiting member 5 and a third flow limiting member 6 arranged on the body 7. A centralized water supply port 71 is formed on the body 7, and the centralized water supply port 71 is connected to an external water supply source, and the first water inlet assembly 1 and the second water inlet assembly 2 are both connected to the centralized water supply port 71.

[0054] It should be noted that the first water inlet assembly 1 and the second water inlet assembly 2 can also use two independent water supply ports, or be directly connected to an external water supply source. Such flexible adjustment and change does not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0055] like Figure 1 , Figure 2 and Figure 6 As shown, the first water inlet assembly 1 includes a first control valve 11 and a first water inlet pipeline 12. The first control valve 11 is preferably a solenoid valve, denoted as the first solenoid valve 11, the inlet of the first solenoid valve 11 (not shown in the figure) is connected to the centralized water supply port 71, the outlet 111 of the first solenoid valve 11 is connected to the water inlet 121 of the first water inlet pipeline 12, the first solenoid valve 11 can control the connection between the first water inlet pipeline 12 and the centralized water supply port 71, and the first flow limiting member 4 is arranged in the outlet 111 of the first solenoid valve 11 (see Figure 6 ), the second flow limiting member 5 is arranged in the first water inlet pipe 12 (see Figure 2 ), that is, the first flow limiting member 4 and the second flow limiting member 5 are arranged in sequence along the flow direction of water, and the flow rate of the first flow limiting member 4 is smaller than the flow rate of the second flow limiting member 5.

[0056] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the second water inlet assembly 2 includes a second control valve 21 and a second water inlet pipeline 22. The inlet of the second control valve 21 (not shown in the figure) is connected to the centralized water supply port 71. The second control valve 21 includes two outlets, which are marked as a first outlet 211 and a second outlet 212. The first outlet 211 is connected to the connecting assembly 3 (see Figure 6 ), the second outlet 212 is connected to the second water inlet pipeline 22 (see Figure 7 ). In a preferred case, the number of the second control valve 21 and the second water inlet pipeline 22 are both two, and the second control valve 21 corresponds to the second water inlet pipeline 22 one by one. The second control valve 21 is also preferably a solenoid valve, denoted as the second solenoid valve 21, which can control the connection and disconnection between the second water inlet pipeline 22 and the connecting component 3 and the centralized water supply port 71.

[0057] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the connecting component 3 includes a connecting pipeline 31 for connecting the first water inlet component 1 and the second water inlet component 2 and a conduction control valve 32 for controlling the on-off of the connecting pipeline 31. The connection between the first water inlet component 1 and the connecting pipeline 31 is located between the first flow limiting component 4 and the second flow limiting component 5. Among them, one end of the connecting pipeline 31 is connected to the water inlet 121 of the first water inlet pipeline 12 (the water inlet 121 is located between the first flow limiting component 4 and the second flow limiting component 5), and the other end of the connecting pipeline 31 is connected to the second outlets 212 of the two second control valves 21; the conduction control valve 32 is preferably a one-way check valve 32, and the number of the one-way check valves 32 is also two, which are respectively arranged in the first outlets 211 of the two second solenoid valves 21 (see for details). Figure 6 ) to prevent water from entering the second solenoid valve 21 from the first outlet 211; the number of the third flow limiting members 6 is also two, which are respectively arranged in the two second water inlet pipes 22 (see Figure 2 ).

[0058] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the connecting pipeline 31 includes an annular plate 311 and a cover plate 312. The bottom of the annular plate 311 is sealed and connected to the body 7 of the water inlet device, and the top of the annular plate 311 is sealed and connected to the cover plate 312, thereby forming a sealed connecting pipeline 31. In a preferred case, the annular plate 311 and the body 7 are integrally formed, and the annular plate 311 and the cover plate 312 are fixedly connected, so as to facilitate the inspection and replacement of the first flow limiting member 4 and the one-way check valve 32.

[0059] It should be noted that the specific structure of the connecting pipe 31 is not limited to the above-mentioned specific structural form. For example, the connecting pipe 31 can be set as a circular tube, one end of the circular tube is connected to the first water inlet pipe 12, and two openings are opened on the side wall of the circular tube, which are respectively connected to the first outlets 211 of the two second solenoid valves 21, and so on. Such adjustments and changes to the specific structural form of the connecting pipe 31 do not deviate from the principle and scope of the present invention, and should be directly limited to the protection scope of the present invention.

[0060] The working principle of the water inlet device of the present invention is introduced below.

[0061] When the first solenoid valve 11 is turned on and the second solenoid valve 21 is turned off, water enters the first water inlet pipe 12 through the first solenoid valve 11, and under the flow limiting effect of the first flow limiting member 4, the flow rate entering the first water inlet pipe 12 is relatively small, so that the first water inlet pipe 12 can provide a small flow rate of water supply. In addition, under the effect of the one-way check valve 32, the water flow will not enter the second solenoid valve 21, let alone the second water inlet pipe 22, that is, in this case, only the first water inlet pipe 12 supplies water at a small flow rate.

[0062] When the first solenoid valve 11 is disconnected, and one of the two second solenoid valves 21 is connected and the other is disconnected, after water enters the connected second solenoid valve 21, it is divided into two streams of water, one of which flows through the first outlet 211 of the second solenoid valve 21 and enters the connecting pipe 31. Since the connecting pipe 31 is connected to the water inlet 121 of the first water inlet pipe 12 (the water inlet 121 is located between the first flow limiting component 4 and the second flow limiting component 5), the water flow will not pass through the first flow limiting component 4, but directly enter the first water inlet pipe 12 along the connecting pipe 31. Under the flow limiting effect of the second flow limiting component 5, the second water inlet pipe 22 can provide a large flow of water supply; the other water flows through the second outlet 212 of the second solenoid valve 21 and enters the second water inlet pipe 22. In addition, under the effect of the one-way check valve 32, the water flow entering the connecting pipe 31 will not enter the second solenoid valve 21 in the disconnected state, and will not enter the second water inlet pipe 22 connected to the second solenoid valve 21 in the disconnected state. That is, in this case, the first water inlet pipe 12 supplies water at a large flow rate, one of the two second water inlet pipes 22 supplies water, and the two second water inlet pipes 22 of the second water inlet assembly 2 can supply water independently without affecting each other.

[0063] When the first solenoid valve 11 is disconnected and the two second solenoid valves 21 are connected, after the water enters the two second solenoid valves 21, each is divided into two streams of water. Taking one of the streams (the second solenoid valve 21+the second water inlet pipeline 22) as an example, one of the two streams of water flows through the first outlet 211 of the second solenoid valve 21 and enters the connecting pipeline 31, and then enters the first water inlet pipeline 12 along the connecting pipeline 31. Under the flow limiting effect of the second flow limiting component 5, the second water inlet pipeline 22 can provide a large flow of water supply. Moreover, under the flow limiting effect of the second flow limiting component 5, whether one second solenoid valve 21 or two second solenoid valves 21 are connected, the water supply of the second water inlet pipeline 22 remains unchanged, thereby realizing precise control of the flow rate; the other stream of water flows through the second outlet 212 of the second solenoid valve 21 and enters the second water inlet pipeline 22. Moreover, since the structures of the two streams (the second solenoid valve 21+the second water inlet pipeline 22) are exactly the same, the flow rates of the two second water inlet pipelines 22 are the same at this time. That is, in this case, the first water inlet pipe 12 supplies water at a large flow rate, and the two second water inlet pipes 22 supply water at the same time and the water supply amount is the same.

[0064] Through such a configuration, the water inlet device of the present invention has at least the following advantages:

[0065] First, the first water inlet pipeline 12 can realize water supply of two different flow rates, thereby reducing one solenoid valve (the price of the solenoid valve is relatively expensive) and one water inlet pipeline, thereby reducing the volume and manufacturing cost of the water inlet device;

[0066] Second, by setting the flow limiting components (the first flow limiting component 4, the second flow limiting component 5 and the third flow limiting component 6), accurate control of the flow rate can be achieved, and in practical applications, different types of flow limiting components can be replaced according to different functions, which is convenient and flexible and has a wider range of applications;

[0067] Third, the two second water inlet pipes 22 can supply water independently (complementary influence) and can supply water at the same time with the same water supply amount. When the two second water inlet pipes 22 supply water at the same time, they can achieve offset and change the flow direction of water, thereby reducing one more solenoid valve and one water inlet pipe. Specifically, in a possible situation, Fig.14 As shown, the detergent dispenser box 8 includes a shell, and three functional areas are arranged inside the shell, namely, a first functional area 81, a second functional area 82 and a third functional area 83, which can be used to store different detergents, and also includes two water inlet pipes 84 connected to the first functional area 81, the second functional area 82 and the third functional area 83. The outlets of the outlet sections 841 of the two water inlet pipes 84 are opposite and inclined. The two water inlet pipes 84 are connected to the two second water inlet pipelines 22 respectively. When only the left water inlet pipe 84 is fed with water, the water flows into the third functional area 83. When only the right water inlet pipe 84 is fed with water, the water flows into the first functional area 81. When the two water inlet pipes 84 are fed with water at the same time, the two water flows collide, and the flow direction of the water changes so that the water flows into the second functional area 82. That is, the water supply to the three functional areas can be realized through the two second water inlet pipelines 22, thereby reducing one solenoid valve and a water inlet pipeline, and further reducing the volume and manufacturing cost of the water inlet device.

[0068] Combine the following Fig. 9 and Fig.10 The structure of the one-way check valve 32 will be described in detail.

[0069] like Fig. 9 and Fig.10 As shown, the one-way check valve 32 includes a valve seat 321 , a return spring 322 and a sealing ring 323 . A guide column 324 is provided on the valve seat 321 . The return spring 322 is sleeved on the guide column 324 . The sealing ring 323 is sleeved on the valve seat 321 .

[0070] In the installed state (the one-way check valve 32 is installed in the first outlet 211 of the second solenoid valve 21), as Figure 3 , Figure 4 and Figure 5 As shown, the bottom end of the return spring 322 abuts against the valve seat 321, and the top end of the return spring 322 abuts against the cover plate 312 of the connecting pipe 31. The cover plate 312 is provided with a guide hole 3121 (see Figure 8 ), the top of the guide column 324 is inserted into the guide hole 3121, and after water enters the second solenoid valve 21, it moves upward against the valve seat 321 to open the first outlet 211, and water enters the connecting pipe 31 from the first outlet 211. After the water inlet is completed, under the action of the reset spring 322, the valve seat 321 moves downward to re-seal the first outlet 211. In the sealed state, the sealing ring 323 is located between the inner wall of the first outlet 211 and the valve seat 321.

[0071] It should be noted that the structure of the one-way check valve 32 does not constitute a limitation to the present invention, and one-way check valves 32 with other structures are also within the protection scope of the present invention.

[0072] Combine the following Figures 11 to 13 The structure of a current limiting component is introduced in detail.

[0073] First, it should be noted that, in this embodiment, the first flow limiting component 4, the second flow limiting component 5 and the third flow limiting component 6 adopt the same type of flow limiting component. Taking the second flow limiting component 5 as an example, Figures 11 to 13 As shown, it includes a flow limiting seat 51 and a flow limiting plate 52. The flow limiting seat 51 is provided with a flow limiting hole 511, a connecting shaft 512, a protrusion 513 and a sealing ring 514. The flow limiting plate 52 is sleeved on the connecting shaft 512. The right side of the flow limiting plate 52 abuts against the protrusion 513 so that there is a gap between the flow limiting plate 52 and the flow limiting seat 51. The gap plays a role of limiting the flow. The size of the gap determines the size of the flow rate. The gap is connected with the flow limiting hole 511, and water flows out of the flow limiting hole 511. When installed, the sealing ring 514 abuts against the inner wall of the first water inlet pipe 12.

[0074] It should be noted that the first flow limiting component 4, the second flow limiting component 5 and the third flow limiting component 6 can all adopt the above-mentioned type of flow limiting components, or can respectively adopt other different types of flow limiting components. Such flexible adjustment and change does not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

[0075] In addition, it should be noted that although the present invention only provides one embodiment for the flow limiting component, those skilled in the art should understand that the contribution of the present invention to the prior art is mainly reflected in that the first flow limiting component 4 (small flow) and the second flow limiting component 5 (large flow) are arranged in sequence on the first water inlet component 1 along the water flow direction, and the connection between the first water inlet component 1 and the connecting component 3 is located between the first flow limiting component 4 and the second flow limiting component 5, so that the first water inlet component 1 can realize water supply of two flow rates and can realize more accurate flow control. Therefore, the use of flow limiting components with other structures is also within the protection scope of the present invention.

[0076] Embodiment 2

[0077] On the basis of other setting conditions of the first embodiment remaining unchanged, the third flow limiting component 6 is removed. When the function corresponding to the second water inlet assembly 2 does not require a high water inlet flow rate, the third flow limiting component 6 can be removed.

[0078] Embodiment 3

[0079] On the basis of other setting conditions of the first embodiment remaining unchanged, one second solenoid valve 21, one-way check valve 32, second water inlet pipeline 22 and third flow limiting member 6 are cancelled. That is, the second water inlet assembly 2 only includes one second solenoid valve 21 and second water inlet pipeline 22, one-way check valve 32 and one third flow limiting member 6, the one-way check valve 32 is arranged in the first outlet 211 of the second solenoid valve 21, and the third flow limiting member 6 is arranged in the second water inlet pipeline 22.

[0080] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
