Description

Technical Field

[0001] This invention relates to the field of nozzle technology, specifically providing a nozzle, a dispensing device, and a washing device. Background Technology

[0002] Washing machines are an essential appliance in people's homes, with a variety of functions, and are loved by many.

[0003] Current washing machines still have some significant problems with washing performance, which not only affect the cleanliness of clothes but may also pose potential threats to consumers' health. Among these, inadequate cleaning is a major issue commonly reported by consumers. When stains on clothes cannot be effectively removed, it not only affects the appearance and wearing experience but may also breed bacteria, adversely affecting the wearer's health. Incomplete detergent dissolution is another important reason for poor washing results. Detergent plays a crucial role in the washing process, but if it cannot dissolve sufficiently, its cleaning power cannot be fully realized. This not only reduces the cleanliness of clothes but may also leave detergent residue. Detergent residue can leave odors and stains on clothes and may also irritate the skin, triggering allergic reactions and other health problems.

[0004] In summary, existing washing machines suffer from problems such as insufficient detergent dissolution and inadequate washing.

[0005] Accordingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0014] In the preferred embodiment of the above-mentioned dispensing device, the dispensing box includes a connected box body and a bottom plate. The box body is provided with the first water inlet. The box body and the bottom plate together form a first water inlet pipe. The first water inlet pipe connects the first water inlet and the mixing chamber.

[0015] In a preferred embodiment of the above-mentioned dispensing device, a first region above the box body is recessed downward to form a penetration cavity, and a first storage cavity is recessed upward below the box body. A liquid infusion pipeline is formed together with the bottom plate below the box body, and the liquid infusion pipeline is connected to the penetration cavity, the first storage cavity, and the mixing chamber; and / or, a second water inlet is formed on the box body, a second water outlet is provided on the bottom plate, and a second water inlet pipeline is formed together with the box body and the bottom plate, and the second water inlet and the second water outlet are connected through the second water inlet pipeline; and / or, a third water inlet is formed on the box body, a second water outlet is provided on the bottom plate, a second storage cavity is recessed downward above the box body, a third water inlet pipeline is formed together with the bottom plate in the region between the third water inlet and the second storage cavity, and a mixing pipeline is formed together with the bottom plate below the second storage cavity, and the mixing pipeline connects the second water outlet and the second storage cavity.

The present invention utilizes the negative pressure created by the water containing the treatment agent flowing through the throttling orifice to draw air into the mixing chamber, forming bubbles, thus fully dissolving the treatment agent. Then, the impact of the curved baffle further breaks up the gas in the fluid, enhancing the bubble effect. Furthermore, the curved baffle allows for diffuse spraying, resulting in a wider application onto clothing.

[0018] Furthermore, the present invention also improves the amount of bubbles by providing a dividing member between the mixing chamber and the liquid outlet, and by utilizing the dividing effect of the dividing member.

[0019] Furthermore, the present invention also facilitates the installation and disassembly of the fastener by providing the first elastic part and the second elastic part, and can also strengthen the connection between the first snap-fit ​​member and the second snap-fit ​​member.

[0038] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications.

[0039] It should be noted that in the description of this invention, terms such as "upper," "lower," "left," and "right," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] First refer to Figures 1 to 3 ,like Figures 1 to 3As shown, the nozzle of the present invention includes: a housing 401, in which a throttling orifice 403, a mixing chamber 404, and a liquid outlet 405 are formed in sequence and connected; an air intake gap 415 is formed in the housing 401, which connects the mixing chamber 404 and the outside of the housing 401; water containing a treatment agent flows through the throttling orifice 403 and forms a negative pressure in the mixing chamber 404, and draws air into the mixing chamber 404 through the air intake gap 415; a curved baffle 406 is provided at the liquid outlet 405, which can both diffuse the fluid and further break up the gas.

[0042] Specifically, when the nozzle of the present invention is in use, the throttling orifice 403 is located above the liquid outlet 405. The negative pressure formed after the fluid passes through the throttling orifice 403 causes air to be drawn into the mixing chamber 404, forming bubbles, which allows the treatment agent to be fully dissolved. After the fluid passes through the liquid outlet 405, it impacts the curved baffle 406 downwards. The impact of the curved baffle 406 further breaks up the gas in the fluid, enhancing the bubble effect. In addition, the curved baffle 406 enables diffusion spraying, which can be more widely applied to clothing.

[0043] Furthermore, the projection of the curved baffle 406 onto the liquid outlet 405 can cover the liquid outlet 405. (See also...) Figure 3 The curved baffle 406 is projected from bottom to top (not shown in the projection diagram) to cover the liquid outlet 405, so that the fluid passing through the liquid outlet 405 can all impact the curved baffle 406.

[0044] like Figure 3 As shown, the curved baffle 406 is a concave curved baffle, which can be a spherical concave curved surface or a spoon-shaped concave curved surface, which can fully diffuse the fluid and expand the spray range of the nozzle.

[0045] like Figure 2 and Figure 3 As shown, a dividing member 407 is provided between the mixing chamber 404 and the liquid outlet 405. The mixture of gas and liquid is divided by the dividing member 407, which can increase the amount of bubbles and improve the dissolution effect of the treatment agent. The dividing member 407 can be a grid structure or a filter screen, as long as it can play a dividing role. The filter screen can be made of stainless steel or polymer materials such as nylon or polypropylene. The dividing member 407 can be a single layer or multiple layers. Those skilled in the art can set it according to the actual situation.

[0046] like Figures 1 to 3As shown, the housing 401 contains a plurality of circumferentially arranged limiting members 408. A fixing member 409 fixes the dividing member 407 to the end of the limiting member 408. The gap between the fixing member 409 and the inner wall of the liquid outlet 405 is a suction gap 415, which communicates with the mixing chamber 404. For details, see [reference needed]. Figure 1 The fastener 409 is provided with a pressing part 4091. When the fastener 409 is installed in place, the pressing part 4091 presses the dividing member 407 to the end of the limiting member 408 to fix the dividing member 407. The pressing part 4091 is a block structure and the fastener 409 is a ring structure. Multiple block structures are arranged circumferentially around the inner side of the fastener 409. Of course, this is not a limitation. The pressing part 4091 can also be a ring structure, forming a stepped ring with the fastener 409. The pressing part 4091 can still press the dividing member 407 to fix the dividing member 407.

[0047] See Figure 3 The fastener 409 includes a first elastic part 4092, which is provided with a first snap-fit ​​member. A second snap-fit ​​member is provided on the inner wall of the housing 401. At least one limiting member 408 includes a second elastic part 4081. When the first snap-fit ​​member and the second snap-fit ​​member are snapped into place, the first elastic part 4092 and the second elastic part 4081 abut against each other, and both the first elastic part 4092 and the second elastic part 4081 deform in a direction away from the second snap-fit ​​member. Their recovery tendency provides elastic force to the first snap-fit ​​member.

[0048] Specifically, the fastener 409 includes a ring-shaped body (not labeled in the figure), on which a first elastic portion 4092 is provided, and a second elastic portion 4081 is provided at the end of the limiting member 408, that is... Figure 3 In the middle, at the lower end of the limiting member 408, the first snap-fit ​​member is a protrusion 4093 provided on the first elastic part 4092, and the second snap-fit ​​member is a groove 410 provided on the inner wall of the housing 401. The protrusion 4093 is inserted into the groove 410 to fix the fixing member 409 to the housing 401. During installation, it is oriented away from the groove 410. Figure 3The middle part is to the right. The first elastic part 4092 and the second elastic part 4081 are pressed to the right. When the protrusion 4093 moves upward to the position corresponding to the groove 410, the pressing is stopped. Under the elasticity of the first elastic part 4092 and the second elastic part 4081, the protrusion 4093 is squeezed into the groove 410. After the protrusion 4093 and the groove 410 are connected in place, the first elastic part 4092 and the second elastic part 4081 are still in a deformed state and deform in the direction away from the groove 410. Their recovery tendency provides elasticity to the protrusion 4093, improving the connection stability. The setting of the first elastic part 4092 and the second elastic part 4081 also facilitates disassembly and replacement of the dividing component 407.

[0049] It should be noted that the present invention does not impose any restrictions on the specific placement of the protrusion 4093 and the groove 410, such as... Figure 3 As shown, it can be set on the left or the right, and those skilled in the art can set it according to the actual situation.

[0050] It should also be noted that the present invention does not impose any limitation on the number of the first elastic part 4092 and the second elastic part 4081. The number of them is the same, and there can be one or more. In the case of multiple, each limiting member 408 is provided with one second elastic part 4081. Those skilled in the art can set it according to the actual situation.

[0051] See next. Figure 1 ,like Figure 1 As shown, a connecting rib 414 is provided inside the housing 401. The connecting rib 414 is used to connect the inner wall of the housing 401 and the limiting member 408. A slot 4094 is provided on the first elastic part 4092. After the fixing member 409 is installed in place, the slot 4094 is locked to the connecting rib 414, which further improves the stability of the fixing member 409.

[0052] like Figure 2 As shown, an expansion portion 4051 is provided at the liquid outlet 405. The diameter of the expansion portion 4051 gradually increases along the water flow direction to facilitate air intake through the air intake gap 415.

[0053] In other embodiments, the intake gap 415 is an intake port located on the side of the housing 401, connecting the mixing chamber 404 and the outside of the housing 401.

[0054] The throttling orifice 403 is preferably a tapered throttling orifice, meaning its cross-sectional area gradually decreases in the direction of water flow, and there is at least one such orifice; the example shows three. The orifice diameter is preferably 1-5 mm, and more preferably 1.5-3 mm.

[0055] A ribbed structure is provided on the inner wall of the throttling orifice 403 to turbulent the flow, thereby increasing the water flow area and enlarging the air intake surface to generate more water mist.

[0056] In a second aspect, the present invention also claims a dispensing device comprising the nozzle described in any of the above embodiments. See also... Figure 4 and 5 The dispensing device includes a first nozzle 4, which is the nozzle described in the above embodiments.

[0057] See next. Figure 2 and 3 , Figures 6 to 8 The dispensing device includes a dispensing box, within which a first inlet 101, a mixing chamber, and a first outlet 205 are formed and connected. A first storage cavity is formed inside the dispensing box, capable of feeding treatment agent into the mixing chamber. The first outlet 205 is connected to an inlet 402. The first outlet 205 is located at the bottom of the dispensing box and dispenses water downwards. An insertion part 411 is provided on the housing 401, which is inserted upwards into the first outlet 205. A sealing groove 412 is provided on the outer side of the insertion part 411, and a sealing ring 413 is fitted inside the sealing groove 412. The sealing ring 413 can achieve a seal after the insertion part 411 and the first outlet 205 are connected. Figure 1 As shown, extensions 416 are provided on both sides of the housing 401, and fixing holes 417 are provided on the extensions 416. A fastening hole is provided on the bottom of the dispensing box. Fasteners pass through the fixing holes 417 and the fastening holes to fix the first nozzle 4 at the first water outlet 205.

[0058] See next. Figures 6 to 8 The dispensing box includes a connected box body 1 and a base plate 2. A first water inlet 101 is provided on the box body 1. The box body 1 and the base plate 2 together form a first water inlet pipe, which connects the first water inlet 101 and the mixing chamber. For example... Figure 6 In the middle, the bottom of the first water inlet 201 and the bottom of the mixing chamber 204 are formed on the bottom plate 2, which are connected to each other, such as Figure 8 As shown, the box body 1 has a first water inlet pipe top 113, a mixing chamber top 120, and a first water outlet connection part 119 connected in sequence. The first water outlet connection part 119 corresponds to the first water outlet 205. The first water inlet pipe top 113 corresponds to the first water inlet bottom 201, together forming a first water inlet pipe. The mixing chamber bottom 204 and the mixing chamber top 120 correspond to each other, together forming a mixing chamber. Water entering from the first water inlet 101 enters the mixing chamber through the first water inlet pipe.

[0059] The upper part of the box 1 is recessed downward to form an infusion chamber 104, and the lower part of the box 1 is recessed upward to form a first storage chamber. The lower part of the box 1 and the bottom plate 2 together form an infusion pipeline, which is connected to the infusion chamber 104, the first storage chamber and the mixing chamber.

[0060] Specifically, using the delivery box in Figure 6 The position shown is the standard, such as Figure 8 As shown, the bottom of the housing 1 has a connected infusion tubing top 116 and a first storage chamber top 118, as shown. Figure 6 As shown, a connected infusion tubing bottom 206 and a first storage chamber bottom 208 are formed above the base plate 2. The infusion tubing top 116 and the infusion tubing bottom 206 correspond to each other to form the infusion tubing. The first storage chamber top 118 and the first storage chamber bottom 208 correspond to each other to form the first storage chamber. The infusion chamber 104 passes through the leak 117 ( Figure 8 (As indicated in the diagram) is connected to the top 116 of the infusion line. The treatment agent in the infusion chamber 104 can enter the first storage chamber through the infusion line. The treatment agents in the infusion chamber 104 and the first storage chamber can also be sent into the mixing chamber through the infusion line.

[0061] like Figure 8 As shown, a drive member chamber 123 is formed on the housing 1 to accommodate the drive member 7. The drive member 7 can be a peristaltic pump, a piston pump, a diaphragm pump, or a gear pump. The drive member is connected to the suction port 124 and the outlet 125. The suction port 124 is connected to the infusion line, and the outlet 125 is connected to the mixing chamber. The drive member draws in the treatment agent from the suction port 124 and then sends the treatment agent into the mixing chamber from the outlet 125.

[0062] In other embodiments, the mixing chamber and the infusion line are directly connected via a drive member 7 to deliver the treatment agent in the infusion line into the mixing chamber.

[0063] The casing of the present invention, through the arrangement of the infusion chamber 104, the infusion tubing, and the first storage chamber, can accommodate more treatment agent. The top 120 and bottom 204 of the mixing chamber are both located below the infusion chamber 104, making more rational use of space. A portion of the top 116 and a portion of the bottom 206 of the infusion tubing are located below the infusion chamber 104, further making the space more compact.

[0064] Continue reading Figures 6 to 8 A second water inlet 102 is formed on the box body 1, and a second water outlet 207 is provided on the bottom plate. The box body 1 and the bottom plate 2 together form a second water inlet pipe, and the second water inlet 102 and the second water outlet 207 are connected through the second water inlet pipe; specifically, as Figure 6In the middle, the second water inlet 102 is located to the left of the first water inlet 101, and the bottom of the second water inlet 202 is formed on the bottom plate 2. The bottom of the second water inlet 202 is located to the left of the bottom of the first water inlet 201, as shown. Figure 8 As shown, a second water inlet pipe top 114 is formed on the box body 1, and the second water inlet pipe top 114 corresponds to the second water inlet bottom 202, as shown. Figure 6 As shown, a first water inlet 105 is formed on the box body 1, as... Figure 7 As shown, the first water inlet 105 includes a first connecting port 1051, a cover plate 1052, and a second connecting port 1053. The first connecting port 1051 is connected to the second water outlet 207, and the cover plate 1052 is corresponding to... Figure 6 The first water outlet 205 is covered by a cover plate 1052 to prevent water that should flow out from the second water outlet 207 from flowing out through the first water outlet 205. This avoids interference between the pipes and improves their independence and stability. The bottom 202 of the second water inlet, the top 114 of the second water inlet pipe, the first connecting port 1051, the cover plate 1052, and the second connecting port 1053 together form the second water inlet pipe. Water enters from the second water inlet 102 and finally flows out through the second water outlet 207.

[0065] Continue reading Figures 6 to 8 A third water inlet 103 is formed on the box body 1, and a second water outlet 207 is provided on the bottom plate. A second storage cavity 106 is formed by a downward indentation in the second area above the box body 1. A third water inlet pipe is jointly formed by the box body 1 and the bottom plate 2 in the area between the third water inlet 103 and the second storage cavity 106. Figure 6 As shown, a third water inlet bottom 203 is formed on the bottom plate 2, and a second water inlet 108 is formed on the box body 1, as... Figure 7 As shown, a baffle 112 is provided between the second water inlet 108 and the second storage chamber 106, such as Figure 8 As shown, a third water inlet pipe top 115 is formed on the box body 1. The third water inlet pipe top 115 is connected to the second water inlet section 108 and corresponds to the third water inlet bottom 203. Water enters the third water inlet bottom 203 from the third water inlet 103, and then the water level rises to the third water inlet pipe top 115, and then enters the second water inlet section 108 from the third water inlet pipe top 115, and then passes over the baffle 112 into the second storage chamber 106.

[0066] A mixing pipe is formed below the second storage chamber 106 and together with the bottom plate 2, the mixing pipe connecting the second outlet 207 and the second storage chamber 106. Figure 6 As shown, a mixing pipe bottom 209 is formed on the base plate 2, and the mixing pipe bottom 209 is connected to the second outlet 207, as shown. Figure 8As shown, the housing 1 has a connected mixing pipe top 121 and a second outlet connection 122. The mixing pipe top 121 and the mixing pipe bottom 209 correspond to each other to form the mixing pipe. The second outlet connection 122 corresponds to the second outlet 207. Figure 6 In the second storage chamber 106, a siphon tube 107 is provided. The siphon tube 107 is connected to the mixing pipeline. The siphon tube 107 is covered with a siphon cap (not shown in the figure). The siphon tube 107 and the siphon cap together form a siphon structure, which can drain the treatment agent in the second storage chamber 106.

[0067] See Figures 6 to 8 The box body 1 has a first overflow section 109 that is connected to the top 121 of the mixing pipe on the box body 1. When the water volume in the third inlet 103 is too large, the liquid in the second storage chamber 106 enters the mixing pipe through the first overflow section 109 and is finally discharged from the second outlet 207.

[0068] A second overflow section 110 is also formed on the box body 1. The second overflow section 110 corresponds to and is connected to the bottom of the second inlet 202. Figure 7 As shown, a pressure relief pipe 111 is provided on the right side of the second overflow section 110. The second overflow section 110 has a perforated structure and a one-way valve is installed inside it. The pressure relief pipe 111 is connected to... Figure 8 The first water inlet pipe is connected to the top 113. When the water pressure at the first water inlet 101 is too high, water flows from the pressure relief pipe 111 to the second overflow section 110 and opens the one-way valve, so that water enters the bottom 202 of the second water inlet from the second overflow section 110 and finally flows out from the second outlet 207.

[0069] The first overflow section 109 and the second overflow section 110, along with the pressure relief pipeline, are arranged in parallel and are surrounded by the first water inlet 101, the second water inlet 102, the third water inlet 103, the second storage chamber 106, the first water inlet 105, and the injection chamber 104. This integrated arrangement greatly reduces the waste of space.

[0070] Furthermore, the dispensing box also includes a cover 3, which is located above the box body 1. After the cover 3 and the box body 1 are connected in place, a gap is formed between the baffle 112 and the cover 3 to allow water to overflow the baffle 112.

[0071] The top cover 3 is provided with a first injection port 31 and a second injection port 32. The first injection port 31 corresponds to the injection cavity 104 to inject a treatment agent into the injection cavity 104. The second injection port 32 corresponds to the second storage cavity 106 to inject a treatment agent into the second storage cavity 106. The treatment agent can be detergent, fabric softener, or fragrance, etc.

[0072] like Figure 4 and Figure 5 As shown, the dispensing device also includes a solenoid valve assembly 5, which has a main water inlet 51. The solenoid valve assembly 5 includes three solenoid valves, which are respectively connected to the first water inlet 101, the second water inlet 102, and the third water inlet 103, and can control the connection status of the first water inlet 101, the second water inlet 102, and the third water inlet 103 with the main water inlet 51. The dispensing device also includes a second nozzle 6, which is connected to the second water outlet 207.

[0073] In other embodiments, an impeller is provided in the mixing chamber. The impeller agitates the water and the solution to be processed, making the dissolution more complete. The impeller can be driven by water flow or by an external drive component, such as a motor installed outside the dispensing box. The drive shaft of the motor is sealed to the impeller to drive the impeller.

[0074] See Figure 6 The bottom plate 2 of the present invention has multiple groove structures, which correspond to the chambers and pipelines on the box body 1 to seal the chambers and pipelines on the box body 1, such as the first storage chamber, infusion pipeline, first water inlet pipeline, second water inlet pipeline, third water inlet pipeline, mixing pipeline, etc. Of course, this is not limiting; the bottom plate 2 can also be a completely flat plate structure, as long as it can seal the bottom of the box body 1.

[0075] In this invention, the first nozzle 4 is connected to the first outlet 205. When water enters through the first inlet 101, the driving component 7 pumps the treatment agent in the first storage chamber into the mixing chamber. The water and the treatment agent are fully mixed in the mixing chamber. Then, the water enters the first nozzle 4 from the first outlet 205. After passing through the throttling orifice 403, a negative pressure is formed in the mixing chamber 404. The negative pressure is used to draw in air. Finally, the water passes through the dividing component 407 to generate more microbubbles to form foam water with the treatment agent.

[0076] When water enters from the second inlet 102, it is a separate water intake, realizing the function of water intake only.

[0077] When water enters through the third inlet 103, the treatment agent can be carried into the washing drum of the washing machine.

[0078] In a third aspect, the present invention also claims a washing apparatus comprising the dispensing device described in any of the above embodiments. The washing apparatus includes a washing drum 8, and the dispensing device is disposed above the washing drum 8. The washing drum 8 includes an outer drum 81 and an inner drum 82 fitted inside the outer drum 81. A first nozzle 4 and a second nozzle 6 are capable of delivering water into the inner drum 82 of the washing drum 8 of the washing machine.

[0079] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles 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 such changes or substitutions will all fall within the scope of protection of the present invention.
