A drawer-type garment processing device

Abstract

This invention provides a drawer-type garment processing device, including a housing, a drawer, a washing drum, and a water-blocking component. The housing has an internal cavity, the drawer is slidably disposed within the cavity and forms a drawer cavity, and the washing drum is rotatably disposed within the drawer cavity and forms a washing chamber. The water-blocking component is located at the opening of the washing drum and includes a water-blocking portion. The water-blocking portion has a guide surface that mates with the inner wall surface of the washing drum's sidewall. During operation, the washing water in the washing chamber flows along the inner wall surface of the drum's sidewall to the guide surface, forming a water curtain under the action of the guide surface. The water-blocking component has a simple structure and prevents water from flowing back into the drying duct. The water curtain flows back into the washing chamber, improving the washing effect and ensuring the washing quality. This solves the problems of existing technologies that use a balance ring to block water flow, which are structurally complex, require a high washing drum height, and are unsuitable for drawer-type washing machines.

Description

Technical Field

[0001] This invention belongs to the field of clothing processing technology, and particularly relates to a drawer-type clothing processing device. Background Technology

[0002] To meet users' needs for washing shoes, shoe washing machines were developed. Typically, shoe washing machines have brushes inside the washing chamber. Controlling the rotation of these brushes allows them to contact the surface of the shoes, achieving the purpose of washing. Existing shoe washing machines include a washing drum and an impeller. The washing drum is rotatably mounted, and the impeller is rotatably mounted inside the washing drum. Brushes are installed on the inner wall of the washing drum and on the top of the impeller. During washing, the inner drum and impeller rotate in opposite directions, agitating the water flow and causing the shoes to tumble inside the inner drum, thus cleaning them with the water flow and brushes. However, because shoe washing machines are generally low in height, water can splash under centrifugal force during the drum's rotation, easily flowing back into the drying duct along the inner wall of the washing drum, causing short circuits and damage to the drying fan. Some have proposed installing a balance ring at the opening of the washing drum, with multiple baffles at its lower end to prevent water from climbing up. However, this structure is complex, requires a high-height washing drum, is unsuitable for drawer-type washing machines, and significantly impacts the capacity of drawer-type washing machines. Summary of the Invention

[0003] In view of this, the present invention provides a drawer-type clothing processing device to solve the problems of complex structure, high requirements for the height of the washing drum, and unsuitability for drawer-type washing machines when using a balance ring to block the water flow in the prior art.

[0019] The third water-blocking section extends radially from the outside to the inside of the washing drum and gradually approaches the axis of the washing drum. The third water-blocking section has a third flow guide section on the side facing the washing chamber.

[0020] Further optionally, the height of the guide surface in the axial direction of the washing drum is h, wherein h satisfies: 133mm≤h≤138.5mm;

[0021] The width of the guide surface in the radial direction of the washing drum is r, and r satisfies: 10mm≤r≤30mm.

[0022] Optionally, the water-blocking component further includes a base, the base having an annular structure and being disposed on the edge of the cylinder opening; the water-blocking portion is disposed on the base and located radially inside the base.

[0023] Further optionally, an annular groove is formed at the bottom of the base, and the annular groove is engaged on the edge of the cylinder opening for limiting the position of the base;

[0024] A water-blocking fixing part is formed on the side wall of the annular groove near the axis of the base, and a cylinder fixing part is formed on the side wall of the cylinder; the water-blocking fixing part and the cylinder fixing part cooperate to connect the water-blocking part and the washing cylinder.

[0025] Further optionally, the drawer-type garment handling device also includes a sidewall brush disposed on the inner wall surface; the base is formed with a clearance opening that can accommodate at least a portion of the sidewall brush.

[0027] Compared with the prior art, the main advantages of the present invention are as follows:

[0028] The water-blocking component is located at the opening of the washing drum and includes a water-blocking part. The water-blocking part has a ring structure and a guide surface is formed on the side of the water-blocking part facing the washing chamber. When the drawer-type clothes handling equipment is running, the washing water in the washing chamber can flow along the inner wall of the washing drum sidewall to the guide surface, and form a water curtain under the action of the guide surface. The water curtain flows from the guide surface to the washing chamber. The structure is simple, has low requirements for the height of the washing drum, and is suitable for drawer-type clothes handling equipment. It can prevent water from flowing back into the drying air duct and avoid the problem of water flowing into the drying air duct causing a short circuit in the drying fan. The water curtain flows back into the washing chamber, improving the washing effect of the washing water, ensuring the washing effect, avoiding resource waste, and solving the problems of complex structure, high requirements for the height of the washing drum, and unsuitability for drawer-type washing machines when using a balance ring to block the water flow in the existing technology.

[0048] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0050] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0051] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0052] Because shoe washing machines are generally low in height, water can splash under centrifugal force during the rotation of the washing drum. This splashing can then easily backflow into the drying air duct along the inner wall of the washing drum, causing short circuits and damage to the drying fan. Some have suggested installing a balance ring at the opening of the washing drum, with multiple baffles at the lower end of the balance ring, to prevent water from climbing up. However, this structure is complex, requires a high height of the washing drum, is not suitable for drawer-type washing machines, and significantly affects the capacity of drawer-type washing machines.

[0053] This invention creatively provides a drawer-type garment processing device, including a housing, a drawer, a washing drum, and a water-blocking component; the housing has an interior cavity, the drawer is slidably disposed within the housing cavity and forms a drawer cavity, the washing drum is rotatably disposed within the drawer cavity and forms a washing chamber; the water-blocking component is disposed at the opening of the washing drum and includes a water-blocking portion; a guide surface is formed on the side of the water-blocking portion facing the washing chamber; when the drawer-type garment processing device is in operation, the washing water in the washing chamber can flow along the inner wall of the side wall of the washing drum to the guide surface, and form a water curtain under the action of the guide surface; the water curtain flows from the guide surface to the washing chamber;

[0054] The water-blocking component has a simple structure and can prevent water from flowing back into the drying air duct; the water curtain flows back into the washing chamber, improving the washing effect of the washing water and ensuring the washing effect.

[0055] Example 1

[0056] like Figures 1a to 6 As shown, this embodiment provides a drawer-type garment processing device, preferably a drawer-type shoe washing machine; the drawer-type garment processing device includes:

[0057] The box 11 has a side wall with an opening and an interior cavity 111 that communicates with the opening. The drawer 12 is slidably installed in the cavity 111 through the opening and has a drawer cavity.

[0058] A washing drum 2 is rotatably disposed within a drawer cavity. The washing drum 2 includes a drum side wall 22, with an opening formed at one axial end of the drum side wall 22 and a bottom wall 21 disposed at the other axial end of the drum side wall 22. The drum side wall 22 and the bottom wall 21 enclose a washing cavity. A drum cover 25 is disposed at the opening of the drum, which can open or close the opening of the washing drum 2. The drum cover 25 is rotatably disposed on the top wall of the drawer 12 on the side near the cabinet cavity 111.

[0059] A water-blocking component 4 is provided at the opening of the washing drum 2 or is integrally formed from the opening of the drum, and the water-blocking component 4 includes a water-blocking part 41; the water-blocking part 41 has a ring structure, and the downward projection of the end of the water-blocking part 41 on the axial direction of the washing drum 2 falls into the washing chamber.

[0060] A guide surface 42 is formed on the side of the water-blocking part 41 facing the washing chamber. The guide surface 42 is in contact with the inner wall surface of the side wall 22 of the drum. The guide surface 42 allows the washing water in the washing chamber to be guided into the washing chamber and form a water curtain when it flows along the inner wall surface to the guide surface 42.

[0061] In summary, the water-blocking component 4 has a simple structure, low height requirements for the washing drum 2, and is suitable for drawer-type garment processing equipment. It can prevent water from flowing back into the drying duct 51, thus avoiding the problem of water flowing into the drying duct 51 causing a short circuit in the drying fan. Under the action of centrifugal force, the water in the washing chamber rises upward along the inner wall of the drum side wall 22. According to the Coanda adhesion effect, the water forms a water curtain at the upper end of the washing drum 2 under the action of the guide surface 42. The water flows back into the washing chamber, effectively preventing water splashing and backflow into the drying duct 51, while not affecting the output of the drying airflow in the drying duct 51, ensuring drying efficiency. The water curtain flowing back into the washing chamber enhances the washing effect of the washing water, ensures the washing effect, avoids resource waste, and solves the problems of complex structure, high height requirements for the washing drum 2, and unsuitability for drawer-type washing machines when using a balance ring to block the water flow upward in the existing technology.

[0062] Example 2

[0063] like Figures 1a to 6 As shown, based on Embodiment 1, the guide surface 42 forms an upwardly convex guide surface, which allows the water curtain to flow to the lower side of the axis of the washing drum 2, thereby improving the washing effect near the axis of the washing drum 2.

[0064] Furthermore, the guide surface 42 includes a first guide surface segment 421, a second guide surface segment 422, and a third guide surface segment 423; the first guide surface segment 421, the second guide surface segment 422, and the third guide surface segment 423 are arranged sequentially from the outside to the inside along the radial direction of the washing drum 2, and form an upwardly convex guide surface;

[0065] The first guide surface section 421 is disposed close to the inner wall surface. The first guide surface section 421 extends upward from the outside to the inside along the radial direction of the washing drum 2 and gradually approaches the axis of the washing drum 2. The second guide surface section 422 extends upward first and then downward along the radial direction of the washing drum 2 and gradually approaches the axis of the washing drum 2. The second guide surface section 422 has an upwardly convex arc-shaped structure. The third guide surface section 423 extends downward from the outside to the inside along the radial direction of the washing drum 2 and gradually approaches the axis of the washing drum 2. The downward projection of the end of the third guide surface section 423 on the axial direction of the washing drum 2 falls into the washing chamber.

[0066] When the drawer-type garment processing equipment is running, the washing water in the washing chamber can flow sequentially along the inner wall of the drum side wall 22 to the first guide surface 42 and the second guide surface 42, forming a water curtain under the action of the third guide surface 42.

[0067] Furthermore, along the radial direction of the washing drum 2, the first guide surface section 421, the second guide surface section 422, and the third guide surface section 423 are all arc-shaped structures;

[0068] The radius of the arc of the first guide surface section 421 is R1, the radius of the arc of the second guide surface section 422 is R2, and the radius of the arc of the third guide surface section 423 is R3. R1, R2 and R3 satisfy: 4mm≤R1<13mm, 10mm≤R2<15mm, 1mm<R3≤5mm.

[0069] The angle between the tangent at the end of the third guide surface section 423 and the horizontal plane is θ, where θ satisfies: 144°≤θ<151°. By limiting the angle θ, the direction of the water flow is controlled to ensure that the water curtain formed by the water flow can converge in the middle of the washing chamber. If the angle θ is too small, the water flow cannot converge in the middle of the washing chamber. If the angle θ is too large, the point where the water flow converges will be too close to the upper edge of the drum opening, and the water flow will splash outside the washing drum 2, affecting the user experience and washing cleanliness (the washing cleanliness is affected because there is less water in the washing drum 2).

[0070] This embodiment also proposes that the water-blocking part 41 includes a first water-blocking section 411, a second water-blocking section 412 and a third water-blocking section 413 arranged sequentially from the outside to the inside along the radial direction of the washing drum 2, and the first water-blocking section 411, the second water-blocking section 412 and the third water-blocking section 413 are all arc-shaped structures.

[0071] The first water-blocking section 411 extends upward from the outside to the inside along the radial direction of the washing drum 2 and gradually approaches the axis of the washing drum 2. The first water-blocking section 411 has a first guide surface section 421 on the side facing the washing chamber 2.

[0072] The second water-blocking section 412 extends radially from the outside to the inside of the washing drum 2, first upward and then downward. A second guide surface section 422 is formed on the side of the second water-blocking section 412 facing the washing chamber 2. The second water-blocking section 412 protrudes upward.

[0073] The third water-blocking section 413 extends downward from the outside to the inside along the radial direction of the washing drum 2 and gradually approaches the axis of the washing drum 2. The bottom wall of the third water-blocking section 413 forms a third flow guide section 423.

[0074] This embodiment also proposes that the height of the guide surface 42 in the axial direction of the washing drum 2 is h, where h satisfies: 133mm≤h≤138.5mm;

[0075] The width of the guide surface 42 in the radial direction of the washing drum 2 is r, and r satisfies: 10mm≤r≤30mm.

[0076] This embodiment also proposes that the water-blocking component 4 further includes a base 43, which has an annular structure and is disposed on the edge of the cylinder opening; the water-blocking part 41 is disposed on the base 43 and located on the radial inner side of the base 43.

[0077] Furthermore, an annular groove 431 is formed at the bottom of the base 43, and the annular groove 431 is engaged on the edge of the cylinder opening for limiting the horizontal direction of the base 43.

[0078] A water-blocking fixing part 432 is formed on the side wall of the annular groove 431 near the axis of the base 43, and a tub fixing part 221 is formed on the side wall 22 of the washing tub 2; the water-blocking fixing part 432 and the tub fixing part 221 cooperate, and the water-blocking part 4 and the washing tub 2 are connected by screws, which limits the water-blocking part 4 in the vertical direction.

[0079] Specifically, the drawer-type garment processing device also includes a side wall brush 32 and a bottom wall brush 31. The side wall brush 32 is disposed on the inner wall surface of the side wall 22 of the drum, and the bottom wall brush 31 is disposed on the inner wall surface of the bottom wall 21 of the drum. The base 43 has an clearance opening 433, which can accommodate at least a portion of the side wall brush 32.

[0080] Both the sidewall brush 32 and the bottomwall brush 31 include a brush seat 33 and multiple brush clusters 34. The brush seat 33 is disposed on the sidewall 22 and the bottomwall 21 of the drum. The multiple brush clusters 34 are disposed on the brush seat 33 for washing. Specifically, the brush seat 33 has multiple brush holes spaced apart. The multiple brush clusters 34 are disposed one-to-one in the multiple brush holes, and the brush clusters 34 are disposed in the brush holes by means of adhesion or snap-fit.

[0081] When washing in a drawer-type garment handling unit, the side wall brush 32 and the bottom wall brush 31 can rotate with the washing drum 2 to wash shoes.

[0082] The drawer-type garment processing equipment also includes a drying duct 51, which has a drying air inlet and a drying air outlet, both of which are connected to the washing drum 2. The drying duct 51 is located at the opening of the washing drum 2 and is positioned above the water baffle 4.

[0083] Furthermore, the top wall of drawer 12 has a drawer opening, and the interior of drawer 12 has a drawer cavity communicating with the drawer opening; the washing drum 2 is rotatably mounted in the drawer cavity through the drawer opening, and a pulsator is installed inside the washing drum 2, with the pulsator located on the bottom wall 21 of the washing drum 2; the bottom wall 21 of the washing drum 2 has a plurality of spaced bottom wall through holes 23, each bottom wall through hole 23 communicating with the washing cavity and the drawer cavity; the side wall 22 of the washing drum 2 has a plurality of spaced side wall through holes 24, each side wall through hole 24 communicating with the washing cavity and the drawer cavity;

[0084] A water-dispersing rib 52 is provided at the connection between the side wall 22 and the bottom wall 21 of the washing drum 2. The water-dispersing rib 52 is located on the outside of the washing drum 2. Multiple water-dispersing ribs 52 are provided, and multiple water-dispersing ribs 52 are arranged at intervals along the circumference of the washing drum 2 to improve water dispersing efficiency and improve washing ratio.

[0085] The bottom wall 21 of the washing drum 2 is provided with reinforcing ribs 53, which are located on the outside of the washing drum 2. Multiple reinforcing ribs 53 are provided, and the multiple reinforcing ribs 53 are spaced apart along the circumference of the washing drum 2. The reinforcing ribs 53 make the bottom wall 21 of the washing drum 2 less prone to deformation.

[0086] The garment handling unit has washing, spin-drying, and drying programs. The washing program includes a main wash and a rinse program. The operation procedure of the garment handling unit is as follows:

[0087] First, the user pulls out drawer 12 from the opening of the cabinet, opens the drum cover 25, and puts clothes or shoes into the washing drum 2;
