TECHNICAL FIELD
[0001] The present application belongs to the technical field of washing equipment, and particularly relates to a washing agent adding device and a washing equipment with the same. BACKGROUND
[0002] With the improvement of people's living standards, various intelligent household appliances are widely used in all aspects of people's life. Taking a washing machine as an example, as one of the indispensable household appliances in modern families, the washing machine has more and more diversified functions to meet various needs of users as much as possible.
[0003] The traditional washing agent adding method of the washing machine is to add the washing agent into the washing barrel through the impact of water flow. Since the water inlet pressure is large, the washing agent is washed into the washing barrel in a short time after water inlet, and efficient mixing of the washing agent and water cannot be realized. Moreover, due to the influence of external temperature and washing agent activity, a long time is needed to completely dissolve the washing agent into water and start effective washing. The low-efficiency washing method before this also consumes corresponding energy and time, so that the clothes cannot be washed clean in a long time, resulting in poor washing effect.
[0004] Moreover, when the water inlet pressure is low, the washing agent cannot be washed clean, and a large amount of washing agent remains in the washing agent box, which not only wastes the washing agent but also causes the washing agent to adhere to the inner wall of the washing agent box for a long time, even breeds bacteria, and causes adverse effects.
[0005] Therefore, the present application is proposed. SUMMARY
[0006] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art, and to provide a washing agent adding device. The water and the washing agent can be fully mixed by adding a mixing device in the washing agent adding device, the washing effect is improved, and the mixed liquid can cover and spray the washing objects by opening the liquid outlet through the movement of the valve assembly, and the washing efficiency is improved.
[0007] To solve the above technical problems, the basic idea of the technical scheme of the present application is as follows: a washing agent adding device, comprising:
[0008] A shell, an inner cavity of the shell is formed;
[0009] A water inlet is arranged on the shell and communicates with the cavity, and is used for water inlet;
[0010] A liquid inlet is arranged on the shell and communicates with the cavity, and is used for washing agent inlet;
[0011] A mixing device is arranged on the shell and at least partially located in the cavity, and is used for mixing water and washing agent to form a mixed liquid;
[0012] An outlet is arranged on the shell and communicates with the shell cavity and is located downstream of the mixing device and is used to discharge the mixed liquid;
[0013] A valve assembly is arranged in the shell cavity and is reciprocally movable to open or close the outlet.
[0014] Further, the valve assembly comprises:
[0015] A valve body is arranged in the shell cavity and is reciprocally movable, one end of the valve body is provided with a containing cavity for containing the mixed liquid;
[0016] An elastic member is arranged at the end of the valve body away from the mixing device, one end of the elastic member is connected with the valve body and the other end is connected with the inner wall of the shell, and the elastic member is used to provide a force for moving the valve body towards the mixing device.
[0017] Further, a limiting part is arranged on the outer surface of the valve body and / or the inner surface of the shell cavity to limit the position of the valve body moving towards the mixing device.
[0018] Further, the mixing device comprises:
[0019] A first pipeline is arranged in the shell cavity, the axial direction of the first pipeline is the same as the axial direction of the shell, one end of the first pipeline communicates with the water inlet and the other end communicates with the containing cavity, and the pressure generated by the water entering the containing cavity is used to provide a force for moving the valve body away from the mixing device;
[0020] A second pipeline is arranged perpendicularly to the first pipeline;
[0021] An installation opening is arranged on the side wall of the first pipeline, and the second pipeline is arranged at the installation opening and communicates with the first pipeline.
[0022] In the above scheme, during the water inlet process, the mixed liquid formed continuously enters the containing cavity, the pressure gradually increases, and the valve body is pushed to move away from the mixing device, thereby opening the outlet, and at the same time, the mixed liquid is sprayed from the outlet under high pressure, realizing the spray washing of the washing object and improving the washing effect.
[0023] By adjusting the water inlet pressure, the speed and distance of the valve body moving away from the mixing device can be adjusted, and the number of the outlet opening can be adjusted.
[0024] Further, the end of the first pipeline communicating with the water inlet gradually reduces in diameter along the direction of the water flow, forming a Venturi structure;
[0025] The communication position of the first pipeline and the second pipeline is located downstream of the Venturi structure.
[0026] Further, a guide fin is arranged on the outer surface of the first pipeline and protrudes from the outer surface of the first pipeline, and the guide fins are arranged at intervals in the circumferential direction of the first pipeline.
[0027] The guide fin has an angle with the axial direction of the first pipeline.
[0028] In the above scheme, by arranging the guide fin on the outer surface of the first pipeline, the flow direction of the water flow is changed by the guiding effect of the guide fin on the water flow, and the flow is disturbed, so that the water and the detergent are mixed more uniformly.
[0029] Further, the outer surface of the first pipeline and the inner surface of the shell cavity have a gap.
[0030] The outer contour diameter of the first pipeline is smaller than the diameter of the containing cavity.
[0031] In the above scheme, the gap between the outer surface of the first pipeline and the inner surface of the shell cavity is to enable a part of the water to pass from the outside of the first pipeline, so as to generate a flow disturbance on the water by the guide fin, thereby improving the mixing degree of the water and the detergent.
[0032] The outer contour diameter of the first pipeline is smaller than the diameter of the containing cavity, so that the water passing from the outside of the first pipeline can also flow into the containing cavity, not only to disturb the flow of the water and the detergent flowing through the first pipeline, but also to increase the force for pushing the valve body to move away from the mixing device, so that the valve body moves a greater distance, thereby opening more liquid outlets.
[0033] Further, the second pipeline communicates with the liquid inlet.
[0034] Alternatively, the shell is provided with a fitting opening, and the second pipeline is arranged at the fitting opening to form the liquid inlet.
[0035] In the above scheme, by arranging the Venturi structure, when the water flows through the Venturi structure, the Venturi effect is generated, and under the action of low pressure, the detergent is siphoned into the first pipeline through the second pipeline, thereby realizing automatic addition of the detergent.
[0036] Further, the liquid outlet is arranged on the bottom wall of the shell and located below the valve body near one end of the mixing device, and is distributed along the axial direction of the shell.
[0037] Preferably, a through hole is arranged on the bottom wall of the containing cavity, and the through hole communicates with the liquid outlet through the shell cavity.
[0038] In the above scheme, the liquid outlet is arranged below the valve body near one end of the mixing device, so that the valve body can open the liquid outlet by moving a small distance, thereby facilitating liquid discharge.
[0039] Meanwhile, by setting the through hole on the bottom wall of the accommodating cavity, the outflow of the mixed liquid flowing into the accommodating cavity is facilitated, and when the pressure decreases and the valve body closes the liquid outlet, the residual water or mixed liquid in the device can flow out from the through hole and then from the liquid outlet, effectively reducing the residual and avoiding waste.
[0040] A washing device having the above-described detergent adding device, the washing device comprising:
[0041] A liquid storage tank in communication with the liquid inlet of the detergent adding device for providing detergent;
[0042] A washing chamber above which the liquid outlet of the detergent adding device is arranged for realizing spray washing.
[0043] After the above technical solution is adopted, the present application has the following beneficial effects compared with the prior art:
[0044] The present application adds a mixing device in the detergent adding device, so that water and detergent can be fully mixed to improve the washing effect.
[0045] In the water inlet process, the mixed liquid formed continuously enters the accommodating cavity, the pressure gradually increases, the valve body is pushed to move away from the mixing device, and then the liquid outlet is opened, and at the same time, the mixed liquid is sprayed out from the liquid outlet under high pressure, realizing the covering spray of the mixed liquid to the washing object and improving the washing efficiency.
[0046] The present application sets the flow guide ribs on the outer surface of the first pipeline, changes the original flow direction of the water flow by the guiding effect of the flow guide ribs, plays a turbulence effect, and makes the mixing of water and detergent more uniform.
[0047] In the present application, a gap is set between the outer surface of the first pipeline and the inner surface of the shell cavity, so that a part of water can pass from the outside of the first pipeline, thereby utilizing the turbulence effect of the flow guide ribs to improve the mixing degree of water and detergent.
[0048] The present application sets the outer contour diameter of the first pipeline to be smaller than the diameter of the accommodating cavity, so that the water passing from the outside of the first pipeline can also flow into the accommodating cavity, not only having a turbulence effect on the water and detergent flowing through the first pipeline, but also increasing the force for pushing the valve body to move away from the mixing device, making the valve body move a greater distance and then opening more liquid outlets.
[0049] The present application sets the Venturi structure on the first pipeline, when water flows through the Venturi structure, the Venturi effect is generated, the detergent is siphoned into the first pipeline through the second pipeline under the action of low pressure, and then the automatic addition of the detergent is realized.

[0066] As an embodiment, the present application provides a detergent adding device, as shown in Figures 1 to 3 The detergent adding device comprises a shell 100, and a shell cavity is formed in the interior of the shell 100.
[0067] The shell 100 comprises a first shell 110 and a second shell 130, the first shell 110 forms a first shell cavity 120, and the second shell 130 forms a second shell cavity 140.
[0068] The first shell 110 and the second shell 130 are both closed at one end and open at the other end, and the first shell 110 and the second shell 130 are detachably connected through the open end.
[0069] In this embodiment, the shell 100 is divided into the first shell 110 and the second shell 130, and the first shell 110 and the second shell 130 are detachably connected, which facilitates the installation, disassembly and maintenance of the device.
[0070] As shown in Figure 3 The diameter of the open end of the second shell 130 is greater than that of the open end of the first shell 110, so that the open end of the first shell 110 can be inserted into the open end of the second shell 130, and the structures of the two are partially overlapped.
[0071] There are various detachable ways, for example, buckles and / or clamping grooves are arranged on the open end of the first shell 110 and / or the second shell 130, and the detachable connection between the first shell 110 and the second shell 130 is realized through the corresponding assembly of the buckles and the clamping grooves; or external threads are arranged on the open end of the first shell 110, and internal threads are arranged on the open end of the second shell 130, and the detachable connection between the first shell 110 and the second shell 130 is realized through the threaded connection, and the like, which are not limited in particular.
[0072] The first shell 110 is provided with at least two water inlets 200, the water inlets 200 are communicated with the first shell cavity 120, and are used for water inlet into the first shell cavity 120.
[0073] Each water inlet 200 is correspondingly provided with a water inlet valve for opening or closing the water inlet 200.
[0074] The water inlet 200 comprises a first water inlet 210 and a second water inlet 220, the first water inlet 210 is a hot water inlet 200, and is correspondingly provided with a hot water valve; and the second water inlet 220 is a cold water inlet 200, and is correspondingly provided with a cold water valve.
[0075] In this embodiment, according to the needs of users in different regions, the users can selectively open the hot water inlet 200 or the cold water inlet 200, meet various needs, and improve the user experience.
[0076] As shown in Figure 3As shown, the first water inlet 210 and the second water inlet 220 are arranged at the closed end of the first shell 110 and are distributed along the axial direction of the first shell 110, and the upper side of the closed end of the first shell 110 is arranged in a stepped structure, so that the horizontal plane where the first water inlet 210 is located is lower than the horizontal plane where the second water inlet 220 is located.
[0077] Meanwhile, a blocking part 230 is arranged below the second water inlet 220, and preferably, the blocking part 230 is in a plate structure.
[0078] The extension direction of the length direction of the blocking part 230 is the same as the axial direction of the first shell 110, one end of the blocking part 230 is connected with the vertical part of the stepped structure, and the other end extends to the open end of the first shell 110; the two ends in the width direction of the blocking part 230 are respectively connected with the inner wall of the first shell cavity 120, so that the water flow entering from the second water inlet 220 is blocked by the blocking part 230 and flows to the downstream direction as soon as possible, and does not interfere with the water flow entering from the first water inlet 210, so that the water inlet can maintain the water inlet pressure and flow to the downstream direction faster.
[0079] It should be noted that the number, position and direction of the water inlets 200 can be set according to actual conditions to meet various water inlet needs.
[0080] The first shell 110 is provided with a liquid inlet 400, which is communicated with the first shell cavity 120 and is used for feeding detergent.
[0081] The first shell 110 is provided with a mixing device 300 near the open end, and the mixing device 300 is at least partially located in the first shell cavity 120 and is used for mixing water and detergent to form a mixed liquid.
[0082] The second shell 130 is provided with a liquid outlet 600, which is communicated with the second shell cavity 140 and is used for feeding the mixed liquid.
[0083] It also includes a valve assembly 500, which is reciprocally arranged in the second shell cavity 140 and is used for opening or closing the liquid outlet 600.
[0084] The valve assembly 500 includes a valve body 510 and an elastic member 520.
[0085] The valve body 510 is reciprocally arranged in the second shell cavity 140 and is located at the open end of the second shell 130.
[0086] The valve body 510 is provided with a containing cavity 511 near the open end of the second shell 130, which is used for containing the mixed liquid.
[0087] The elastic element 520 is disposed at the closed end of the second housing 130. One end of the elastic element 520 is connected to the valve body 510, and the other end is connected to the inner wall of the second housing 130, for providing a force for the valve body 510 to move in the direction of the mixing device 300.
[0088] The elastic element 520 is a spring.
[0089] like Figure 3 As shown, the valve body 510 has a valve stem at one end near the elastic member 520. The outer diameter of the valve stem is smaller than the outer diameter of the receiving cavity 511. One end of the elastic member 520 is connected to the valve stem.
[0090] The diameter of the closed end of the second cavity 140 is smaller than the diameter of the open end. The diameter change point is located at the connection between the valve stem and the elastic element 520, and the second cavity 130 at the diameter change point is conical.
[0091] The elastic element 520 is placed at the closed end of the second housing 130 with a smaller diameter, so that the diameter of the cavity at the closed end matches the diameter of the elastic element 520. While ensuring that the elastic element 520 can undergo elastic deformation, the stability of the elastic element 520 is increased, and the swaying of the elastic element 520 causes the valve body 510 to be unable to move normally.
[0092] A limiting portion 700 is provided on the outer surface of the valve body 510 and / or the inner surface of the cavity to limit the position of the valve body 510 moving toward the mixing device 300.
[0093] like Figure 3 As described above, when the valve body 510 moves toward the mixing device 300 to a predetermined position, the liquid outlet end of the mixing device 300 and the liquid inlet end of the receiving cavity 511 are in the same vertical plane or partially overlap.
[0094] The diameter of the open end of the first cavity 120 is larger than the diameter of the closed end. Therefore, a step is formed on the inner wall of the first cavity 120 where the diameter changes. The step is the limiting part 700. The end of the valve body 510 with the receiving cavity 511 abuts against the limiting part 700.
[0095] It should be noted that the limiting part 700 can also be provided on the outer surface of the valve body 510, as long as it can limit the position of the valve body 510 moving in the direction of the mixing device 300.
[0096] like Figure 2As shown, the liquid outlet 600 is arranged on the bottom wall of the second shell 130, close to the open end of the second shell 130, below the valve body 510.
[0097] In the present embodiment, the liquid outlet 600 is arranged close to the open end of the second shell 130, so that the valve body 510 only needs to move a small distance to open the liquid outlet 600, facilitating liquid outlet.
[0098] The liquid outlet 600 is provided in multiple groups, and the multiple groups of liquid outlets 600 are arranged in a circumferential direction on the bottom wall of the second shell 130, and each group of liquid outlets 600 is uniformly distributed along the axial direction of the second shell 130, so that the liquid outlet directions of the liquid outlets 600 are different, increasing the coverage area.
[0099] The bottom wall of the containing cavity 511 is provided with a through hole, and the through hole is in communication with the liquid outlet through the second shell cavity 140.
[0100] In the present embodiment, the through hole is arranged on the bottom wall of the containing cavity 511, facilitating the outflow of the mixed liquid flowing into the containing cavity 511, and when the pressure decreases and the valve body 510 closes the liquid outlet 600, the residual water or mixed liquid in the device can flow out from the through hole and then from the liquid outlet 600, effectively reducing the residual and avoiding waste.
[0101] It should be noted that the size of the through hole is small and basically does not affect the pressure generated when the mixed liquid flows into the containing cavity 511.
[0102] As shown in Figure 4 and Figure 5 The mixing device 300 includes a first pipeline 310 and a second pipeline 320.
[0103] The first pipeline 310 is arranged in the first shell cavity 120, and the axial direction of the first pipeline 310 is the same as the axial direction of the first shell 110. One end of the first pipeline 310 is in communication with the water inlet 200, and the other end is in communication with the containing cavity 511. The containing cavity 511 generates pressure due to the increase of water inflow, which provides a force for moving the valve body 510 away from the mixing device 300.
[0104] The second pipeline 320 is arranged perpendicularly to the first pipeline 310.
[0105] The first pipeline 310 is provided with a mounting port on the side wall, and the second pipeline 320 is arranged at the mounting port and in communication with the first pipeline 310.
[0106] In this embodiment, during the water intake process, the mixed liquid formed continuously enters the receiving cavity 511, and the pressure gradually increases, pushing the valve body 510 to move away from the mixing device 300, thereby opening the liquid outlet 600. At the same time, under high pressure, the mixed liquid is sprayed out from the liquid outlet 600 to achieve spray washing of the laundry and improve the washing effect.
[0107] At the end of the first pipeline 310 connected to the inlet 200, the diameter of the pipeline gradually decreases along the direction of water flow, forming a Venturi structure 311.
[0108] Preferably, the region with a gradually decreasing diameter is cone-shaped.
[0109] The connection between the first pipe 310 and the second pipe 320 is located downstream of the Venturi structure 311.
[0110] Preferably, the end of the second pipe 320 that connects to the first pipe 310 is inverted cone shape. When the detergent passes through this point, it will have an accelerating effect, which is beneficial to improve the mixing degree of detergent and water.
[0111] In this embodiment, by setting up a Venturi structure 311, when water flows through the Venturi structure 311, a Venturi effect is generated, and under low pressure, the detergent is siphoned through the second pipe 320 into the first pipe 310, thereby realizing the automatic addition of detergent.
[0112] The surface of the pipe body at the inlet end of the first pipe 310 is smoothly transitioned to reduce the resistance when water flows through.
[0113] It also includes guide ribs 312, which are disposed on the outer surface of the first pipe 310 and protrude from the outer surface of the first pipe 310. The guide ribs 312 are spaced apart in the circumferential direction of the first pipe 310.
[0114] The axial direction of the guide rib 312 is at an angle to the axial direction of the first pipeline 310.
[0115] like Figure 4 As shown, the guide rib 312 includes a first body and a second body. The first body is straight and its axial direction is the same as that of the first pipe 310. The second body is arc-shaped and connected to the first body. The axial direction of the second body is at an angle to the axial direction of the first pipe 310.
[0116] In this embodiment, by providing a guide rib 312 on the outer surface of the first pipe 310, the guide rib 312 guides the water flow, changes the original flow direction of the water flow, and plays a turbulence role, so that it mixes more evenly with the detergent.
[0117] It should be noted that the guide ribs 312 can also be in a wave shape or the like, as long as they can guide and disturb the water flow.
[0118] The first pipe 310 has a gap between its outer surface and the inner surface of the shell cavity.
[0119] In the present embodiment, the gap between the outer surface of the first pipe 310 and the inner surface of the shell cavity is to enable a portion of the water to pass from the outside of the first pipe 310, so that the guide ribs 312 can disturb the water flow and improve the mixing degree of the water and the detergent.
[0120] The outer profile diameter of the first pipe 310 is smaller than the diameter of the accommodating cavity 511.
[0121] In the present embodiment, the outer profile diameter of the first pipe 310 is smaller than the diameter of the accommodating cavity 511, so that the water passing from the outside of the first pipe 310 can also flow into the accommodating cavity 511, and the guide ribs 312 can not only disturb the water and detergent flowing through the first pipe 310, but also increase the force to move the valve body 510 away from the mixing device 300, so that the valve body 510 can move a greater distance and open more liquid outlets 600.
[0122] The second pipe 320 is in communication with the liquid inlet 400, or the shell 100 is provided with a fitting opening, and the second pipe 320 is arranged at the fitting opening to form the liquid inlet 400.
[0123] In the present embodiment, when the liquid inlet end of the second pipe 320 is in communication with the liquid inlet 400, the detergent enters the liquid inlet 400 and passes through the second pipe 320 into the first pipe 310 to realize the mixing of the water and the detergent.
[0124] Alternatively, the fitting opening and the liquid inlet 400 are the same structure, the second pipe 320 is installed at the fitting opening and protrudes from the upper surface of the second shell 130, and the detergent directly enters the first pipe 310 from the second pipe 320 to realize the mixing of the water and the detergent.
[0125] As an embodiment, the present application provides a washing device having a detergent adding device as described above.
[0126] The washing device includes a liquid storage tank in communication with the liquid inlet 400 of the detergent adding device for providing the detergent.
[0127] The liquid storage tank includes a plurality of storage chambers for storing the detergent, softener, etc., and each storage chamber is provided with a dispensing opening which can be selectively opened or closed, and each dispensing opening can be in communication with the liquid inlet 400.
[0128] The washing device further comprises a washing chamber, and the liquid outlet 600 of the detergent adding device is arranged above the washing chamber to realize spray washing.
[0129] Taking a pulsator washing machine as an example, the washing chamber is a washing drum.
[0130] The pulsator washing machine has a disc seat, and the detergent adding device is arranged on the disc seat, so that the liquid outlet 600 is arranged above the washing drum to realize spray washing of clothes.
[0131] Correspondingly, the mounting portion 800 is arranged on the housing 100 of the detergent adding device to mount the detergent adding device on the disc seat.
[0132] Specifically,
[0133] When the washing machine is started and a washing program is selected, the water inlet valve is opened, water enters the first housing cavity 120 from the water inlet 200, part of the water flows into the first pipeline 310, and when passing through the Venturi structure 311, the Venturi effect is generated, and the detergent is siphoned into the first pipeline 310 under the action of low pressure to realize mixing of water and detergent; the other part of the water passes through the outside of the first pipeline 310 and flows to the tail of the first pipeline 310 under the guiding action of the guide ribs 312, and the mixed liquid is subjected to the flow disturbance effect, and the mixing degree is further improved.
[0134] The formed mixed liquid continuously flows into the containing cavity 511, the pressure gradually increases, the valve body 510 is driven to move away from the mixing device 300, and the liquid outlet 600 is opened, and at the same time, the mixed liquid is sprayed out from the liquid outlet 600 under high pressure and enters the washing drum, at the same time, a small amount of mixed liquid flows out from the through hole of the bottom wall of the containing cavity 511 and enters the washing drum through the liquid outlet 600, realizes spray washing of clothes, and improves the washing effect.
[0135] When the water inlet is finished, the pressure gradually decreases and disappears, the valve body 510 moves to the direction close to the mixing device 300 due to the loss of force, and the liquid outlet 600 is closed, at this time, the residual water or mixed liquid in the device can flow out from the through hole and then enter the washing drum through the liquid outlet 600, effectively reducing the residual and avoiding waste.
[0136] It should be noted that the washing device can also be a drum washing machine, a dishwasher and the like.
[0137] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application in any form.
