Description

Technical Field

[0001] This invention belongs to the field of clothing processing technology, specifically, it relates to an additive dispensing device, a clothing processing cabinet and its control method. Background Technology

[0002] Existing clothing handling equipment mainly includes washing machines and dryers. Washing machines remove various contaminants from clothes by agitating and rotating water, detergent, and clothes, creating friction and impact on the clothes. Dryers are used to automatically dry damp clothes after washing. However, in both washing machines and dryers, clothes are stacked in the clothes handling drum. When the washing or drying cycle is over, the clothes taken out of the drum have many wrinkles, resulting in a poor user experience.

[0003] With the continuous improvement of people's living standards, the types of clothing processing equipment are becoming increasingly diverse, and the functions of clothing processing equipment are becoming more and more diversified. Clothing care cabinets have emerged as a result. Clothing care cabinets can deodorize, smooth, iron and care for clothes, making them look as good as new, and are widely welcomed by users.

The clothes to be washed are hung inside the washing chamber, and the water inlet assembly supplies water to the spray assembly, which then sprays water into the washing chamber to remove stains from the surface of the clothes. However, during the washing process, the clothes hanging inside the washing chamber lack relative movement and friction, and the effect of simply rinsing with water cannot effectively remove the stains attached to the clothes, resulting in low cleanliness and affecting the user experience.

[0070] Example 1

[0071] like Figures 1 to 10 As shown, an embodiment of the present invention provides an additive dispensing device 400, comprising:

[0072] Liquid storage unit 41, the liquid storage unit 41 includes a plurality of liquid storage chambers for storing additives;

[0073] Dispensing unit 42, wherein the dispensing unit 42 is provided corresponding to the liquid outlet of the liquid storage chamber;

[0074] The temporary storage container 43 is provided with a temporary storage cavity 431, which has an inlet corresponding to the dispensing unit 42. The temporary storage cavity 431 is provided with a microemulsion generating unit 44 for preparing additive microemulsions.

[0075] In this embodiment, stubborn stains are pretreated with an additive microemulsion. The nano-sized microemulsion penetrates into the fabric pores, increasing the concentration of local enzymes and surfactants. The microemulsion particles and the stains act mechanically to aid in cleaning, thus solving the problem of stubborn stains being difficult to remove in traditional washing processes.

[0076] Two or more mutually insoluble liquids are mixed and emulsified, and the diameters of the dispersed droplets are between 5 nm and 100 nm, and the system is called a microemulsion. A microemulsion system is usually a transparent or translucent liquid stable system composed of oil, water, surfactant, co-surfactant, electrolyte, and the like, and is widely used in many fields such as food, medicine, cosmetics, and petroleum.

[0077] As shown in Figure 8 In this embodiment, the microemulsion generating unit 44 includes an ultrasonic generator 441 arranged in the temporary storage cavity 431. The additives stored in the liquid storage cavity flow into the temporary storage cavity 431 through the corresponding dosing unit 42, and the ultrasonic generator 441 is used to ultrasonically treat the additives in the temporary storage cavity 431 to prepare additive microemulsion.

[0078] In this embodiment, two or more mutually insoluble additives are treated by the ultrasonic generator 441 to form additive microemulsion with a diameter of 5 nm to 100 nm. The additive microemulsion has good emulsification, foaming, penetration, decontamination, and dispersion performance, thereby improving the decontamination capacity of the additive.

[0079] As shown in Figure 8 In this embodiment, the microemulsion generating unit 44 further includes a stirring paddle 442 and / or a homogenizer arranged in the temporary storage cavity 431. The stirring paddle 442 and / or the homogenizer are used to stir and / or homogenize the additives in the temporary storage cavity 431.

[0080] In this embodiment, the stirring paddle 442 and / or the homogenizer sufficiently stir and / or homogenize the two or more mutually insoluble additives, so that the different additives are fully mixed to form a uniform and stable additive solution. The ultrasonic generator 441 is then used to ultrasonically treat the stirred and / or homogenized additive solution to form additive microemulsion with good stability and without layering.

[0081] As shown in Figures 2 to 7 In this embodiment, the dosing unit 42 includes a peristaltic pump 43, a first dosing pipeline 422, and a second dosing pipeline 4223. The liquid inlet of the peristaltic pump 43 is in communication with the liquid outlet of the liquid storage cavity through the first dosing pipeline 422, and the liquid outlet of the peristaltic pump 43 is in communication with the liquid inlet of the temporary storage cavity 431 through the second dosing pipeline 4223.

[0082] In this embodiment, by adjusting the operation parameters such as the running time, speed, and flow rate of the peristaltic pump 43, the dosing data of the additive such as the dosing sequence, dosing amount, and dosing time can be accurately controlled, the automatic dosing of the additive is realized, the dosing accuracy of the additive is ensured, and the stability of the additive microemulsion is ensured.

[0083] AsFigures 2 to 7 As shown in this embodiment, the peristaltic pump 43 has a multi-stage diversion channel inside. The first dispensing pipe 422 and the second dispensing pipe 4223 are connected to the inlet and outlet of the corresponding diversion channel. An output control valve 424 is provided on the diversion channel.

[0084] In this embodiment, the peristaltic pump 43 has a multi-stage diversion channel inside, which realizes the sequential or simultaneous delivery of different additives, ensuring that multiple additives flow into the temporary storage chamber 431 sequentially or simultaneously. The control method of the peristaltic pump 43 is more simplified, the flow rate of the peristaltic pump 43 is stable, and multiple additives can be simultaneously controlled to be delivered at the same or different flow rates.

[0085] like Figures 5 to 8 As shown, in this embodiment, the first delivery pipeline 422 includes an integrally connected vertical pipeline section 4221 and a horizontal pipeline section 4222. The top end of the vertical pipeline section 4221 is set to correspond to the liquid outlet of the liquid storage chamber, and one end of the horizontal pipeline section 4222 is set to correspond to the liquid inlet of the peristaltic pump 43. The middle part of the vertical pipeline section 4221 is an inverted frustum-shaped cone with a radial dimension that gradually narrows from top to bottom.

[0086] In this embodiment, the additive in the storage chamber flows into the vertical pipe section 4221 through the outlet. Under the action of the peristaltic pump 43 and its own gravity, the additive can flow more smoothly into the temporary storage chamber 431. In particular, the middle part of the vertical pipe section 4221 is an inverted frustum shape with a radial dimension that gradually narrows from top to bottom, which has a good drainage effect and improves the efficiency of additive delivery.

[0087] like Figure 1 As shown, in this embodiment, the liquid storage unit 41 includes a handle 411 for pulling out and opening the liquid storage chamber, so that the user can conveniently add the corresponding additives into the liquid storage chamber.

[0088] Specifically, the additive microemulsion formulation includes 5-7% lauryl glycoside, 5-7% decyl glycoside, 3-5% sorbitan sesquioleate (Span-83), 3-5% polyglycerol-3-diisostearate, 0.5-1% nuclease, 0.5-1% lipase, 0.3-0.7% sodium stearate, 8-12% coconut oil, 0.3-0.7% sodium benzoate, and 50-60% water. The above additives flow into the temporary storage chamber 431, and the ultrasonic generator 441 sonicates at a vibration frequency of 20 kHz for 5 minutes to form the additive microemulsion.

[0089] Specifically, such as Figure 9 and Figure 10As shown, the spray arm 21 comprises an upper spray arm 212 rotatably arranged on the top wall 11 of the washing cavity 100, and the upper spray arm 212 is used for spraying the clothes hung in the washing cavity 100 from top to bottom. The water inlet pipeline 31 comprises an upper water inlet pipeline 311 arranged at the center of the top wall 11 of the washing cavity 100 and opening downward, and a mounting member 25 is arranged between the upper spray arm 212 and the upper water inlet pipeline 311, and the mounting member 25 is used for detachably connecting the upper spray arm 212 and the upper water inlet pipeline 311.

[0090] In this embodiment, the upper water inlet pipeline 311 passes through the center of the top wall 11 of the washing cavity 100 and opens vertically downward, and a mounting member 25 is arranged between the upper spray arm 212 and the upper water inlet pipeline 311, and the mounting member 25 can quickly clamp the upper spray arm 212 on the upper water inlet pipeline 311.

[0091] In this embodiment, after the upper spray arm 212 is connected with the upper water inlet pipeline 311, the upper spray arm 212 can rotate freely relative to the upper water inlet pipeline 311.

[0092] In addition, the upper spray arm 212 can be freely connected and detached with the upper water inlet pipeline 311 through clamping, so that the upper spray arm 212 can be easily cleaned and replaced.

[0093] As shown in Figure 9 and Figure 10 In this embodiment, the mounting member 25 comprises a clamping protrusion 25a and a clamping hoop 25b, the clamping protrusion 25a is symmetrically arranged on the outer peripheral wall of the upper water inlet pipeline 311, and the clamping protrusion 25a extends horizontally outward along the radial direction of the upper water inlet pipeline 311.

[0094] The clamping hoop 25b is rotatably arranged in the upper spray arm 212, the clamping hoop 25b is provided with a clamping hole 25c, the clamping hole 25c has a vertical section 25c1 extending downward from the upper end surface of the clamping hoop 25b and a horizontal section 25c2 extending horizontally along the outer peripheral wall of the clamping hoop 25b, and the clamping protrusion 25a is clamped with the horizontal section 25c2 of the clamping hole 25c.

[0095] As shown in Figure 10 In this embodiment, a plurality of clamping protrusions 25a are welded on the outer peripheral wall of the upper water inlet pipeline 311, and the plurality of clamping protrusions 25a are arranged in an annular array around the center of the upper water inlet pipeline 311. Preferably, the number of the plurality of clamping protrusions 25a is two, and the two clamping protrusions 25a are symmetrically arranged on the two sides of the outer peripheral wall of the upper water inlet pipeline 311. The clamping protrusion 25a extends outward perpendicular to the axis of the upper water inlet pipeline 311.

[0096] As Figure 10 shown in the embodiment, the clasp 25b is connected to the cavity of the upper spray arm 212, wherein the clasp 25b is annular, the clasp 25b has a vertical segment 25c1 extending downward from the upper end thereof and a horizontal segment 25c2 extending along the outer peripheral wall of the clasp 25b, and the vertical segment 25c1 and the horizontal segment 25c2 are connected to form an L-shaped opening.

[0097] In the embodiment, when the upper spray arm 212 is clamped to the upper water inlet pipeline 311, the vertical segment 25c1 of the clasp 25b is aligned with the clamping protrusion 25a and the clamping protrusion 25a is slid to the vertical segment 25c1, then the clasp 25b is rotated so that the clamping protrusion 25a is rotated to the horizontal segment 25c2, the clamping protrusion 25a abuts against the side wall of the horizontal segment 25c2, and the quick connection of the upper spray arm 212 to the upper water inlet pipeline 311 is completed.

[0098] As Figure 10 shown in the embodiment, the upper water inlet pipeline 311 is composed of a first upper water inlet pipeline 311a and a second upper water inlet pipeline 311b having different outer diameters. The outer diameter of the first upper water inlet pipeline 311a is greater than that of the first upper water inlet pipeline 311a, so that when the first upper water inlet pipeline 311a is connected to the second upper water inlet pipeline 311b, a convex surface is formed at the connection position of the two pipelines. When the upper water inlet pipeline 311 is clamped to the upper spray arm 212, the upper end surface of the clasp 25b is in close contact with the convex surface, so that the entire connection assembly is more tightly fitted and more beautiful. At the same time, when the upper end surface of the clasp 25b is in close contact with the convex surface, the stability of the rotation of the upper spray arm 212 can be ensured, and the upper spray arm 212 can always be kept in the same rotation plane without shaking.

[0099] In the embodiment, two inclined inclined surfaces are symmetrically arranged at the upper end of the clamping protrusion 25a, and a flat surface and / or a curved surface is arranged between the two inclined surfaces for smooth transition.

[0100] In the embodiment, the two symmetric inclined surfaces at the upper end of the clamping protrusion 25a are machined by cutting process, that is, the inclined angles are derived. The two inclined surfaces have a flat surface therebetween, that is, the upper end of the clamping protrusion 25a does not have a pointed end, and the two inclined surfaces form the shape of the clamping protrusion 25a under the smooth transition of the flat surface.

[0101] In this embodiment, after the clamping protrusion 25a slides to the opening of the vertical section 25c1 of the clamping hoop 25b, it needs to rotate to the horizontal section 25c2. Due to the setting of the inclined surface, the inclined surface of the clamping protrusion 25a and the corner of the horizontal section 25c2 rotate smoothly without collision, which ensures the integrity of the clamping protrusion 25a and the side wall of the clamping interface 25c and improves the service life.

[0102] Another embodiment is to set the transition part between the two inclined surfaces as a curved surface, which is integrally formed by injection molding. The curved transition can facilitate the smooth rotation of the clamping protrusion 25a on the horizontal section 25c2. Meanwhile, the curved surface of the clamping protrusion 25a contacts the connection between the horizontal section 25c2 and the vertical section 10c1, and does not cause large wear.

[0103] As shown in the drawings, Figure 10 In this embodiment, the upper spraying arm 212 has a spraying cavity 211, and the upper side of the upper spraying arm 212 is provided with a mounting port 2121 which communicates with the spraying cavity 211.

[0104] As shown in the drawings, Figure 10 In this embodiment, the outer peripheral wall of the lower end of the clamping hoop 25b is provided with a shoulder 25d which extends into the spraying cavity 211 to limit the axial outward movement of the clamping hoop 25b relative to the mounting port 2121.

[0105] In this embodiment, the upper spraying arm 212 has a hollow structure and has a spraying cavity 211 inside. The upper side of the upper spraying arm 212 is provided with a mounting port 2121 which penetrates the spraying cavity 211. The outer peripheral wall of the clamping hoop 25b near the lower end is provided with a shoulder 25d which can be fixedly sleeved on the outer peripheral wall of the clamping hoop 25b or integrally formed with the clamping hoop 25b by injection molding.

[0106] In this embodiment, at least the shoulder 25d in the clamping hoop 25b extends into the spraying cavity 211, thereby completing the connection of the clamping hoop 25b on the upper spraying arm 212. The clamping hoop 25b can rotate in the spraying cavity 211, and the vertical downward projection of the mounting port 2121 can be completely projected on the shoulder 25d.
