Description

Technical Field

[0001] This invention belongs to the field of clothing processing equipment, specifically, it relates to a dispensing device and clothing processing equipment for clothing processing. Background Technology

[0002] In the field of garment processing equipment, automatic detergent dispensing technology has become an important direction for improving washing efficiency and user experience. Traditional dispensing modules typically use a pump to extract detergent or add it manually, then introduce water through an inlet valve to flush the detergent into the garment processing equipment. However, this dispensing method has some obvious shortcomings in practical applications.

[0003] Specifically, in traditional dispensing modules, the detergent often fails to dissolve effectively due to insufficient mixing between water and detergent during the washing process. This results in uneven detergent distribution within the washing machine drum and relatively little foam formation. Foam is a crucial factor in the washing process, helping detergent penetrate clothing fibers more effectively to remove stains.

[0004] Insufficient detergent dissolution and inadequate foam formation negatively impact the washing efficiency (i.e., washing effect) of clothes. The washing efficiency is a crucial indicator of a washing machine's performance, directly affecting the user experience and the cleanliness of the clothes. Therefore, existing automatic detergent dispensing modules have significant limitations in terms of washing efficiency and effectiveness.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The purpose is to provide a dispensing device for a clothing treatment equipment. By providing a foaming structure in the dispensing water path of the dispensing water box, a negative pressure is formed when liquid is introduced through the foaming structure. Air is drawn from the outside atmosphere through the air intake on the dispensing water box and mixed with the additive mixture. The foaming nozzle generates rich foam, thereby improving the washing effect.

[0007] Another object of the present invention is to provide a garment processing device.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is to provide a dispensing device for a clothing processing equipment, comprising:

[0009] The water dispensing box has a water dispensing channel for dispensing additive mixtures;

[0010] The outlet of the water delivery channel has a connected bubble-forming structure;

[0011] The water dispensing box is equipped with an air intake that connects the foaming structure to the outside atmosphere. When the additive mixture enters the foaming structure, a negative pressure is generated, which is used to draw in the outside atmosphere through the air intake for mixing and foaming.

[0012] Furthermore, the two ends of the extending direction of the foaming structure are the inlet end and the outlet end;

[0013] The foaming structure includes a mixing chamber and an air intake chamber. The mixing chamber is connected in the water delivery path. The side wall of the mixing chamber is connected to the air intake chamber. The air intake port is connected to the inlet end of the air intake chamber. After liquid enters the mixing chamber, a negative pressure is generated, and gas is drawn in from the air intake port through the air intake chamber.

[0014] Furthermore, the upper part of the water dispensing box has a ventilation passage that extends to the outlet of the water dispensing passage, and the inlet end of the foaming structure is connected to the outer wall of the ventilation passage.

[0015] A through-hole is provided at the location opposite to the air exchange passage and the air intake chamber, and the air intake is located on the air exchange passage outside the foaming structure:

[0016] Preferably, the water dispensing box also has a dispensing chamber that is independently set apart from the water dispensing path. The dispensing chamber has a manual additive dispensing port and a water outlet that are connected to each other. The ventilation path is connected to the dispensing chamber through the air intake port and is connected to the outside atmosphere through the water outlet.

[0017] Furthermore, the ventilation path includes a cavity, the foaming structure extends downward from the outside of the bottom wall of the cavity, the air inlet is disposed on the bottom wall of the cavity, and the air intake is disposed on the side wall of the cavity;

[0018] Preferably, the bottom wall of the cavity is provided with a plurality of through holes spaced apart in the circumferential direction to form the air vent, and the side wall of the cavity is provided with a plurality of connecting holes spaced apart in the circumferential direction to form the air intake.

[0019] Furthermore, the foaming structure has a circumferentially extending partition structure, the space between the outer wall of the foaming structure and the partition structure forms an air intake cavity, and the partition structure forms a mixing cavity;

[0020] The air intake is located on the outer periphery of the outlet of the water delivery channel, and the inlet end of the air intake chamber is connected to the air intake.

[0021] Preferably, the water dispensing box includes a water injection box and a baffle, and the bottom of the water injection box and the baffle are assembled to form the foaming structure and the partition structure between them.

[0022] Furthermore, the separation structure includes multiple extension arms, which are spaced apart circumferentially; one end of each extension arm protrudes inward and has a certain gap in the radial direction with the adjacent extension arm, connecting the intake chamber and the mixing chamber.

[0023] Furthermore, it also includes a foaming nozzle, which is installed in conjunction with the outlet end of the foaming structure and the outlet end of the separating structure;

[0024] Preferably, the foaming nozzle includes a nozzle disposed at the outlet end of the foaming structure;

[0025] The foaming section is installed inside the foaming structure, sandwiched between the inner circumferential side of the separating structure and the nozzle, and is positioned opposite to the outlet end of the mixing chamber.

[0026] Furthermore, the foaming section includes an annular mounting bracket and a foaming net. One axial end of the mounting bracket is inserted into the outlet end of the partition structure, and the other end is fixedly mounted on the inner peripheral wall of the nozzle. The foaming net is located at the opening of the mounting bracket and is used to form bubbles when the gas and additive mixture passes through.

[0027] Furthermore, the inlet end of the mixing chamber is closed and has an inlet hole, through which the additive mixture flows into the mixing chamber;

[0028] The area of ​​the air intake is smaller than the area of ​​the inlet. When the additive mixture flows into the mixing chamber, a change in flow rate is generated to create negative pressure. The external atmospheric gas is drawn in through the air intake under the negative pressure.

[0029] Preferably, the inlet end of the mixing chamber has multiple inlet holes, each of which is a tapered opening whose size gradually narrows along the liquid flow direction.

[0031] Preferably, it includes a control panel base, and the dispensing device is mounted on the control panel base.

[0032] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0033] (1) This invention incorporates a foaming structure at the outlet of the water delivery channel in the water delivery box, and an air intake on the water delivery box that connects to the outside atmosphere and the foaming structure. Due to the rapid flow of the additive mixture into the foaming structure, a negative pressure is generated within it. This negative pressure effect drives outside air to be drawn into the foaming structure through the air intake, where it mixes with the additive mixture. Subsequently, abundant foam is formed through the foaming nozzle and can be delivered into the garment processing equipment, allowing the foamed additive to directly act on the garments, thus improving washing efficiency and effectiveness. This invention utilizes the principle of negative pressure self-priming, achieving automatic mixing of air and the additive mixture without the need for an additional power source, thereby reducing energy consumption.

[0034] (2) The present invention utilizes the manual additive dispensing chamber to be connected to the outside atmosphere. When dispensing automatically, the foaming structure is connected to the dispensing chamber through the air intake, thereby realizing the connection with the outside atmosphere of the dispensing water box, and successfully drawing in gas from the outside to mix with the additive liquid to create foam.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] like Figures 1 to 8 As shown, this embodiment provides a dispensing device for a garment processing equipment, used to automatically or manually dispense additives such as detergents, fabric softeners, and disinfectants during the garment processing process.

[0053] The garment processing equipment includes household and commercial garment processing equipment such as top-loading washing machines, front-loading washing machines, washer-dryer combos, and garment care machines. In this embodiment of the invention, for ease of description, a top-loading washing machine is used as an example. The garment processing equipment includes a housing, inside which is an outer tub for holding water. Washing components, such as an inner tub, a pulsator, an agitator column, and a second pulsator, can be installed inside the outer tub, rotating under the influence of a motor to agitate the water. The outer tub of the garment processing equipment has a vertically oriented axis and an upward-facing opening. An inner tub is coaxially mounted inside the outer tub. A control panel is installed on the top of the housing, and the control panel has an additive dispensing device connected to the water inlet structure of the garment processing equipment to allow water to enter the outer tub from the tub opening.

[0054] The dispensing device includes a dispensing water box 1, which has a dispensing water channel 11 for dispensing additive mixture into the clothing treatment equipment.

[0055] The outlet of the water dispensing channel 11 has a connected foaming structure 111. The water dispensing box 1 is provided with an air intake 121 that communicates with the outside atmosphere, and the foaming structure 111 is connected to the air intake 121. When the additive mixture enters the foaming structure 111, a negative pressure is generated inside the foaming structure 111. The negative pressure is used to draw outside air into the interior through the air intake 121 for mixing. The air and additive liquid generate foam through the foaming nozzle 2 and are then dispensed into the clothing treatment equipment.

[0056] This invention features a foaming structure 111 at the outlet of the water inlet 11 of the water inlet box 1, and an air intake 121 on the water inlet box 1 connecting to the outside atmosphere and the foaming structure 111. Due to the rapid flow of the additive mixture into the foaming structure 111, a negative pressure is generated within it. This negative pressure effect drives outside air to be drawn into the foaming structure 111 through the air intake 121, where it mixes with the additive mixture. This mixture then forms abundant foam through the foaming nozzle 2, which can be dispensed into the garment processing equipment, allowing the foamed additive to directly act on the garments, thus improving washing efficiency and effectiveness. This invention utilizes the negative pressure self-priming principle to achieve automatic mixing of air and the additive mixture without the need for an additional power source, reducing energy consumption.

[0057] The dispensing water channel 11 is a channel inside the dispensing water box 1 used to guide the flow of the additive mixture. Preferably, the dispensing water channel 11 has a liquid inlet 115 and a water inlet 114. The additive enters the dispensing water channel 11 through the liquid inlet 115, and water enters the dispensing water channel 11 through the water inlet 114, mixes with the additive, and then flows into the foaming structure 111. The dispensing water channel 11 is equipped with a one-way valve to prevent the water from flowing backwards to the water outlet 132.

[0058] The air intake 121 can be directly installed on the outer wall of the water dispensing box 1, communicating with the outside atmosphere. Alternatively, it can be connected to the outside atmosphere of the water dispensing box 1 through a passage or pipe with a certain extension length. The shape and position of the air intake 121 can be adjusted according to actual needs; for example, it can be configured as multiple small holes evenly distributed on the water dispensing box 1.

[0059] The two ends of the extending direction of the foaming structure 111 are the inlet end and the outlet end. For ease of description, we will take the upper end as the inlet end and the lower end as the outlet end as an example. Of course, other methods such as left-right setting, tilting setting, etc., can also be used to set the inlet end and outlet end.

[0060] The foaming structure 111 includes a mixing chamber 1111 and an air intake chamber 1112. The mixing chamber 1111 is connected to the water dispensing channel 11, and the sidewall of the mixing chamber 1111 is connected to the air intake chamber 1112. The air intake port 121 is connected to the inlet end of the air intake chamber 1112. The additive mixture in the water dispensing channel 11 enters the mixing chamber 1111 at high speed, generating a negative pressure in the mixing chamber 1111. Gas is then drawn in from the outside atmosphere through the air intake chamber 1112 and the air intake port 121, which are connected to the mixing chamber 1111. The gas and the additive mixture are aerated by the foaming nozzle 2 and then sprayed out.

[0061] The mixing chamber 1111 and the suction chamber 1112 are arranged side by side along the extending direction, or the mixing chamber 1111 is located on the inner or outer periphery of the suction chamber 1112. The water delivery channel 11 includes a mixing channel and a foaming structure 111. The liquid inlet 115 and the water inlet 114 are located on the mixing channel. The inlet end of the mixing chamber 1111 is closed and communicates with the mixing channel through an inlet hole 1113 on the closed end. The outlet end of the mixing chamber 1111 is open and communicates with the foaming nozzle 2.

[0062] The upper part of the water dispensing box 1 has a ventilation passage 12, and the infusion channel is also located on the upper part of the water dispensing box 1. The ventilation passage 12 extends to the outlet of the water dispensing passage 11, which is the end of the infusion channel. The inlet end of the foaming structure 111 is connected to the outer wall of the ventilation passage 12, that is, the inlet end of the suction chamber 1112 is connected to the outer wall of the ventilation passage 12. The inlet hole 1113 is located in the infusion channel next to the ventilation passage 12 and connects to the mixing chamber 1111.

[0063] A through-hole 122 is provided at the location opposite to the air intake chamber 1112 in the ventilation passage 12, and the air intake 121 is located in the ventilation passage 12 at a position not opposite to the foaming structure 111. Through the aforementioned air intake 121, air intake chamber 1112, air intake 122, and mixing chamber 1111, outside air can enter the foaming structure 111 more smoothly, effectively ensuring the uniformity and efficiency of air introduction and improving foam quality.

[0064] The ventilation path 12 can be a channel with a certain extension length, a cavity with a certain depth, or a combination of both. The cavity can be cylindrical, cuboid, etc.

[0065] The ventilation passage 12 is U-shaped and located at the end of the infusion channel. The foaming structure 111 extends downward from the end of the infusion channel.

[0066] The water dispensing box 1 also has a dispensing chamber 13, which is independently set from the water dispensing channel 11. The dispensing chamber 13 has a manual additive dispensing port 131, which is connected to the dispensing chamber 13 for manually adding additives, and a water outlet 132. The user can manually add additives to the dispensing chamber 13 through the manual additive dispensing port 131. After water is introduced, the additives are mixed and dispensed into the outer container through the water outlet 132. The ventilation channel 12 is connected to the dispensing chamber 13 through the air intake port 121 and is connected to the outside atmosphere through the water outlet 132. This invention utilizes the connection between the manually dispensed additive dispensing chamber 13 and the outside atmosphere. During automatic dispensing, the foaming structure 111 is connected to the dispensing chamber 13 through the air intake port 121, thereby achieving communication with the outside atmosphere of the water dispensing box 1 and successfully drawing in gas from the outside to mix with the additive liquid to create foam.

[0067] The air intake 121 can be located on the side wall, top wall, or bottom wall of the ventilation passage 12, on the outer periphery of the foaming structure 111. The ventilation passage 12 is curved and extended into an arc shape, and is arranged side by side with the infusion channel in the top of the water dispensing box 1.

[0068] The ventilation path 12 includes a cavity. The water dispensing box 1 has a storage chamber 14, and a dispensing cavity 13 is located on the outer periphery of the dispensing cavity 13 for receiving and storing additives, and for facilitating communication between the air intake 121 and the dispensing cavity 13. The water dispensing box 1 has a storage chamber 14, and the dispensing module includes a dispensing pump 3 located at the bottom of the water dispensing box 1, with its inlet and outlet connected to the storage chamber 14 and the inlet 115 of the water dispensing path 11, respectively.

[0069] The foaming structure 111 extends downward from the outside of the bottom wall of the cavity, the vent 122 is located on the bottom wall of the cavity, and the air intake 121 is located on the side wall of the cavity. Specifically, the cavity is cylindrically recessed into the upper part of the water dispensing box 1, and the outer shell 112 of the foaming structure 111 extends downward from the bottom edge of the outer side of the cavity in a cylindrical shape. The air intake 121 is located at the top of the side wall of the cavity.

[0070] Preferably, the bottom wall of the cavity is provided with a plurality of through openings spaced apart circumferentially, forming the vent 122. The side wall of the cavity is provided with a plurality of connecting openings spaced apart circumferentially, forming the intake port 121.

[0071] The shape of the through opening or connecting opening can be elongated, rectangular, circular, etc.

[0072] Furthermore, the foaming structure 111 has a circumferentially extending partition structure 113, which divides the internal space of the foaming structure 111. The space between the outer wall of the foaming structure 111 and the partition structure 113 forms an air intake chamber 1112, and the partition structure 113 forms a mixing chamber 1111. The partition structure 113 has a gap connecting the inner and outer sides.

[0073] The water dispensing box 1 includes a water filling box 15, a box cover 16, a sealing cover 18, and a baffle 17. After assembly, the water filling box 15, box cover 16, and baffle 17 form the foaming structure 111 and the partition structure 113. The box cover 16 is located at one end of the top of the water filling box 15. After assembly, the water filling box 15, box cover 16, and baffle 17 form a liquid storage chamber 14 and a dispensing chamber 13, wherein the additive inlet of the liquid storage chamber 14 and the dispensing chamber 13 is located on the box cover 16. The water outlet 132 extends from the baffle 17. The box cover 16 has an additive dispensing port 141, which communicates with the liquid storage chamber 14. The additive manual dispensing port 131 is located on the box cover 16 and communicates with the dispensing chamber 13.

[0074] The sealing cap 18 is fastened to the other end of the top of the water injection box 15, forming a partial water injection path 11 and a ventilation path 12. The other end of the top of the water injection box 15 is provided with two channel walls, and the sealing cap 18 is fastened to the top of the two channel walls to form a closed water injection path 11 and a ventilation path 12.

[0075] The water injection box 15 is equipped with multiple water inlet pipes, which respectively supply water to the water delivery channel 11 and the delivery cavity 13.

[0076] The partition structure 113 includes multiple extension arms, which are spaced apart circumferentially to form a wall. One end of each extension arm protrudes inward and has a certain gap in the radial direction with the adjacent extension arm, connecting the intake chamber 1112 and the mixing chamber 1111.

[0077] The extension arm includes a first arm 1131, a second arm 1132, and a third arm 1133. The first arm 1131 extends circumferentially in an arc shape. The second arm 1132 extends radially inward from the end of the first arm 1131. The third arm 1133 continues to extend in an arc shape from the end of the second arm 1132 along the extending direction of the first arm 1131. The third arm 1133 of one extension arm is located on the inner ring side of the first arm 1131 of the next adjacent extension arm, and a gap is provided.

[0078] The height of the second arm 1132 is lower than the height of the first arm 1131 and the third arm 1133.

[0079] The foaming nozzle 2 is installed in conjunction with the outlet end of the foaming structure 111 and the outlet end of the partition structure 113.

[0080] The foaming nozzle 2 includes a nozzle 22 and a foaming part 21. The nozzle 22 is disposed on the outlet end of the foaming structure 111, and the foaming part 21 is installed inside the foaming structure 111, sandwiched between the partition structure 113 and the inner circumferential side of the nozzle 22. The foaming part 21 is disposed opposite to the outlet end of the mixing chamber 1111.

[0081] The nozzle 22 has a first protrusion 221 on its inner peripheral wall. The bottom of the foaming part 21 is fixed on the first protrusion 221, and the top of the foaming part 21 is inserted into the gap between the multiple extension arms of the partition structure 113.

[0082] The foaming section 21 includes an annular mounting bracket 211 and a foaming net 212. One axial end of the mounting bracket 211 is inserted into the gap at the outlet end of the partition structure 113, and the other end is fixedly mounted on the first protrusion 221 on the inner peripheral wall of the nozzle 22. The foaming net 212 is disposed at the opening of the mounting bracket 211, covering the opening of the mounting bracket 211, and is used to form bubbles when the gas and additive mixture passes through.

[0083] The mounting bracket 211 has multiple grooves 2114 on its other axial end face (i.e., the lower end face) that engage with the first protrusion 221. The inner ring wall of the mounting bracket 211 has multiple inwardly protruding second protrusions 2111, and the foaming net 212 is sandwiched between the second protrusions 2111 and the bottom wall of the third arm 1133.

[0084] Because the height of the second arm 1132 is lower than the height of the first arm 1131 and the third arm 1133, the axial end face (i.e., the upper end face) of the mounting bracket 211 has a plurality of upwardly protruding, spaced third protrusions 2112. The top surface of the third protrusion 2112 is provided with a radially extending through groove 2113. The third protrusion 2112 is inserted into the gap between adjacent first arms 1131 and third arms 1133, and the through groove 2113 is engaged with the bottom of the second arm 1132.

[0085] The nozzle 22 is fixed to the baffle 17 by a connector, thereby pressing and fixing the mounting bracket 211 between the first protrusion 221 of the nozzle 22 and the second arm 1132 of the partition structure 113. The liquid outlet channel of the nozzle 22 is bent, and the outlet of the nozzle 22 faces the opening of the outer barrel.

[0086] The area of ​​the air intake 121 is smaller than the area of ​​the inlet 1113. When the additive mixture flows into the mixing chamber 1111, a change in flow rate is generated to produce negative pressure. The external atmospheric gas is drawn in through the air intake 121 under the action of negative pressure.

[0087] Preferably, the inlet end of the mixing chamber 1111 has multiple inlet holes 1113, each inlet hole 1113 being a tapered opening whose size gradually narrows along the liquid flow direction, so as to guide the laundry detergent mixture more smoothly into the mixing chamber 1111 from the inlet hole 1113. Optionally, in order to further enhance the liquid flow effect at the inlet hole 1113, multiple guide notches arranged at intervals and extending in different radial directions can be provided on the outer periphery of the inlet hole 1113. The bottom of the guide notch extends downward from the outer periphery to the inner periphery, so as to guide the additive mixture in the water channel 11 to converge and flow into the mixing chamber 1111 through the inlet hole 1113; the guide notch is a strip-shaped fan-shaped groove 2114 protruding outward from the radial direction of the inlet hole 1113, so as to maximize the coverage area of ​​the inlet hole 1113 and guide the laundry detergent mixture in the water channel 11 to flow more smoothly into the foaming mixing chamber 1111. Optionally, the maximum outer diameter of the guide notch is greater than the radial dimension of the inlet hole 1113, so as to further increase the guiding effect of the guide notch.

[0088] The present invention also provides a garment processing device, including any of the above-described dispensing devices.

[0089] The garment handling equipment includes an outer drum and a control panel, with the dispensing device mounted on the control panel. The nozzle of the dispensing device faces the opening of the outer drum.
