Description

Technical Field

[0001] The utility model relates to the technical field of clothing treatment, in particular to a feeding box and a clothing treatment device. Background Art

[0002] The feeding box of a washing machine is generally assembled by a handle and a box body. In the related art, the handle and the box body of the feeding box are usually connected by a buckle, generally by aligning and snap-fitting a protrusion on the buckle with a card hole. Such a buckle structure has relatively high requirements for the matching accuracy of each other. When the card hole is too large or too small, the protrusion and the card hole will not be stably matched, making it difficult to ensure the firm connection between the box body and the handle, and it is easy to become loose during use, affecting the use of the feeding box.

In the present utility model, by arranging the clamping portion to pass out of the first through-hole to abut against the first connecting member instead of arranging a clamping hole in the first through-hole to be in alignment and clamping with the clamping portion, the connection structure between the two is simplified. During assembly, it is only necessary to ensure that the clamping portion can abut against the first connecting member, making it easier to control the fitting accuracy. There will be no situation where the connection between the two is unstable due to the clamping hole being too large or too small as in the related art, which can effectively prevent the connection between the clamping portion and the first connecting member from loosening, improve the firmness of the connection between the first connecting member and the second connecting member, thereby improving the firmness of the connection between the first component and the second component, and not affecting the normal use of the delivery box.

[0010] According to some embodiments of the present utility model, a clearance groove is provided inside the main body, and the clamping portion can move into the clearance groove under an external force so that the clamping portion can pass through the first through-hole.

In the present utility model, by setting the clamping portion to pass out of the first through hole to abut against the first connecting member instead of setting a clamping hole in the first through hole to be in alignment and clamping with the clamping portion, the connection structure between the two is simplified. During assembly, it is only necessary to ensure that the clamping portion can abut against the first connecting member, and it is easier to control the fitting accuracy. There will be no situation where the connection between the two is unstable due to the clamping hole being too large or too small as in the related art, which can effectively avoid the loosening of the connection between the clamping portion and the first connecting member, improve the firmness of the connection between the first connecting member and the second connecting member, and thus improve the firmness of the connection between the first component and the second component, without affecting the normal use of the feeding box.

[0037] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0038] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as up, down, etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0039] In the description of the present utility model, "a plurality of" means more than two. If the first and the second are described, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0040] In the description of the present utility model, unless otherwise clearly defined, terms such as "arrangement", "installation", and "connection" should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0041] This application provides a dosing box. The dosing box is applied to a laundry treatment device, and the laundry treatment device can be an electrical device such as a washing machine or a washer-dryer. Specifically, the dosing box is used to contain detergent and to dispense the detergent into the laundry treatment device when needed.

[0042] In an embodiment of this application, the dosing box includes a first component and a second component, and the first component and the second component are connected by a snap component.

[0043] In the related art, the box body and the handle on the dosing box are usually connected by snaps. Generally, the protrusion on the snap is aligned and snapped with the card hole. When the card hole is set too large, the limit between the snap and the protrusion is unstable; when the card hole is too small, the protrusion cannot completely enter the card hole for alignment, and the connection is unstable. Therefore, this type of snap structure has high requirements for the fitting accuracy. Whether the card hole is too large or too small, it is difficult to ensure the firmness of the snap alignment connection, resulting in easy loosening during use and affecting the normal use of the dosing box.

[0044] In this regard, the snap component of the dosing box of this application can solve the above problems. Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of the snap component of an embodiment of the present utility model, Figure 2 is a cross-sectional view of the snap component of an embodiment of the present utility model. The snap component 300 includes a first connecting member 310 and a second connecting member 320. The first connecting member 310 is provided with a first through hole 310a, and the first through hole 310a axially penetrates the first connecting member 310. The second connecting member 320 includes a main body 321 and a clamping portion 322 connected to the outer wall of the main body 321. The main body 321 passes through the first through hole 310a, and the main body 321 is in direction-limiting cooperation with the hole wall of the first through hole 310a. The clamping portion 322 penetrates out of the first through hole 310a and abuts against the first connecting member 310.

[0045] Among them, the first connecting member 310 is disposed on the first component 100, and the second connecting member 320 is disposed on the second component 200. Through the above connection function of the first connecting member 310 and the second connecting member 320, the first component 100 and the second component 200 can be connected together.

[0046] It should be noted that the limiting cooperation between the main body 321 and the hole wall of the first through hole 310a means that the main body 321 contacts the first through hole 310a, and the first through hole 310a restricts the degree of freedom of the main body 321 to move in a direction perpendicular to the hole wall of the first through hole 310a. Taking the first through hole 310a as a cylindrical hole as an example, the direction perpendicular to the hole wall of the first through hole 310a is the radial direction of the first through hole 310a, then the first through hole 310a restricts the degree of freedom of the main body 321 to move along its radial direction. As Figure 1 shown, a three-dimensional space coordinate system is established with the center line in the depth direction of the first through hole 310a as the Z axis, and the X-axis and Y-axis directions are in the direction perpendicular to the hole wall of the first through hole 310a. That is to say, the limiting cooperation between the main body 321 and the hole wall of the first through hole 310a realizes the limitation of the main body 321 in at least two coordinate axes of the X axis and the Y axis in the three-dimensional space.

[0047] It can be understood that the clamping portion 322 can be configured to pass through the first through hole 310a by relying on the deformation of its own material. In this case, the clamping portion 322 and the first through hole 310a are in an interference fit; or, an avoidance space is provided in the main body 321, and the clamping portion 322 is configured to be able to move relative to the main body 321 so that it is located in the avoidance space when entering the first through hole 310a to realize passing through the first through hole 310a.

[0048] In the embodiment of the present utility model, for the snap component 300, the second connecting member 320 includes a main body 321 and a clamping portion 322. By passing the main body 321 through the first through hole 310a of the first connecting member 310, the main body 321 is in limit fit with the hole wall of the first through hole 310a, and by passing the clamping portion 322 out of the first through hole 310a to abut against the first connecting member 310, the connection with the first connecting member 310 is achieved. In the present utility model, by arranging the clamping portion 322 to pass out of the first through hole 310a to abut against the first connecting member 310, rather than arranging a clamping hole in the first through hole 310a to be in alignment and snap connection with the clamping portion 322, the connection structure between the two is simplified. During assembly, it is only necessary to ensure that the clamping portion 322 can abut against the first connecting member 310, making it easier to control the fitting accuracy. There will be no situation where the connection between the two is unstable due to the clamping hole being too large or too small as in the related art, which can effectively prevent the loosening of the connection between the clamping portion 322 and the first connecting member 310, improve the firmness of the connection between the first connecting member 310 and the second connecting member 320, and thus improve the firmness of the connection between the first component 100 and the second component 200, without affecting the normal use of the delivery box 10.

[0049] Moreover, in the present utility model, by arranging the clamping portion 322 to pass out of the first through hole 310a to abut against the first connecting member 310, there is a larger operating space outside the first connecting member 310, which is more convenient for operating the clamping portion 322. For example, when it is necessary to disassemble and separate the first component 100 and the second component 200, it is convenient to directly push the clamping portion 322 by hand or a tool, and the abutting effect between the clamping portion 322 and the first connecting member 310 can be easily released, facilitating subsequent maintenance.

[0050] It should also be pointed out that in the present utility model, by arranging the main body 321 to be in limit fit with the first through hole 310a, a single snap component 300 alone achieves limit in at least two coordinate axis directions in three-dimensional space. Compared with conventional snaps, the connection firmness between the first connecting member 310 and the second connecting member 320 is better, the number of snaps required between the first component 100 and the second component 200 can be reduced, and the overall structure and assembly of the delivery box 10 are simplified.

[0051] In one embodiment, please continue to refer to Figure 1 and Figure 2 , a clearance groove 321a is arranged in the main body 321, and the clamping portion 322 can move into the clearance groove 321a under an external force.

[0052] Specifically, during the process of inserting the main body 321 into the first via hole 310a, the hole wall of the first via hole 310a will exert extrusion on the clamping portion 322, generating an extrusion force on the clamping portion 322, and pushing the clamping portion 322 to move into the clearance groove 321a, so that the clamping portion 322 can pass through the first via hole 310a. With such a setting, during the process of the clamping portion 322 passing through the first via hole 310a, the clamping portion 322 is located in the clearance groove 321a, and it contacts the hole wall of the first via hole 310a instead of being in an interference fit. The resistance received during the movement process is small, enabling the operator to apply a relatively small force to push the clamping portion 322 through the first via hole 310a to abut against the first connecting member 310, reducing the clamping difficulty between the first connecting member 310 and the second connecting member 320, and facilitating the assembly of the first component 100 and the second component 200.

[0053] Moreover, precisely because the clearance groove 321a is provided on the main body 321 to enable the movement of the clamping portion 322, there is no need to reserve a space for the movement of the clamping portion 322 between the hole wall of the first via hole 310a and the outer wall of the main body 321, making the hole wall of the first via hole 310a contact the outer wall of the main body 321, restricting the degree of freedom of the main body 321 to move in the direction perpendicular to the hole wall of the first via hole 310a. In this way, with only a single snap component 300, the limit in at least two coordinate axes directions in the three-dimensional space is achieved, making the connection between the first connecting member 310 and the second connecting member 320 highly firm. Thus, the number of snaps required between the first component 100 and the second component 200 can be reduced, simplifying the connection structure and assembly, and at the same time reducing the production cost.

[0054] In one embodiment, the main body 321 is configured as a cylindrical shape (or tubular shape) to form the above-mentioned clearance groove 321a inside the hollow of the main body 321. In this way, the structure of the main body 321 is simple, facilitating production and manufacturing, and at the same time reducing the material cost.

[0055] Among them, the contour shape of the main body 321 can be various. The main body 321 can be designed as a square tube, a circular tube, a polygonal tube, etc. The embodiments of the present application do not limit this.

[0056] In one embodiment, the first connecting member 310 is a columnar structure with the above-mentioned first via hole 310a provided inside. One end of the first connecting member 310 away from the first component 100 abuts against the second component 200, and the first connecting member 310 is clamped between the clamping portion 322 and the second component 200.

[0057] Specifically, the distance between the surface of the clamping portion 322 that abuts against the first connecting member 310 and the second component 200 is equal to (or approximately equal to, considering manufacturing errors, there may be a small deviation between the two) the axial length of the first through hole 310a, so that when the clamping portion 322 passes through to the outside of the first through hole 310a and abuts against one end of the first connecting member 310, the second component 200 can just abut against the other end of the first connecting member 310.

[0058] Through the abutting action between the clamping portion 322 and one end of the first connecting member 310, and the abutting action between the second component 200 and the other end of the first connecting member 310, the degree of freedom of relative movement of the first connecting member 310 and the second connecting member 320 along the axial direction of the first through hole 310a is restricted, that is Figure 2 the degree of freedom in the Z-axis direction, realizing the limit in the three coordinate axis directions in three-dimensional space. Then, on the basis of the structure of the above embodiment, in this embodiment, by clamping the first connecting member 310 between the clamping portion 322 and the second component 200, the limit in the three coordinate axis directions in three-dimensional space is realized only by a single snap component 300. Thus, only by setting one snap component 300 can the first component 100 and the second component 200 be stably connected, which can further reduce the number of snaps and further simplify the connection structure and assembly of the dispensing box 10.

[0059] In one embodiment, please refer to Figure 3 , Figure 3 which is a schematic structural diagram of the dispensing box according to the embodiment of the present utility model. The dispensing box 10 includes a box body and an end cover connected to the box body. The box body is provided with a plurality of receiving grooves, and detergents such as laundry detergent, fabric softener, and bactericidal liquid are respectively received in different receiving grooves. An installation groove is provided in the housing of the laundry treatment device, and the box body is movably arranged in the installation groove. For example, the box body is slidably arranged in the installation groove in a pull-out manner, and the housing is provided with an opening for the box body to be pulled out, and the opening is communicated with the installation groove. When the box body is located in the installation groove, the end cover is used to cover the opening to hide the box body inside the laundry treatment device, and the end cover can be used as the appearance structure of the laundry treatment device to improve the aesthetics of the washing machine. The end cover can be provided with a handle groove to facilitate the user to pull the box body out of the installation groove.

[0060] Among them, the above-mentioned first component 100 can be one of the box body and the end cover, and the second component 200 is the other of the box body and the end cover, so that the box body and the end cover are connected by the above-mentioned snap component 300. It can be understood that the first connecting member 310 can be arranged on the box body, and the second connecting member 320 is arranged on the end cover; or, the first connecting member 310 is arranged on the end cover, and the second connecting member 320 is arranged on the box body. The embodiments of the present application do not limit this.

[0061] Please refer to Figure 4 , Figure 5 andFigure 6 , Figure 4 The structural schematic diagram of the buckle assembly according to the embodiment of the present invention applied to the delivery box, Figure 5 is Figure 4 the cross-sectional view of the delivery box shown, Figure 6 is Figure 5 the partial enlarged view of A in

[0062] Connect the box body and the end cover of the delivery box 10 through the above-mentioned first connecting member 310 and second connecting member 320. Since the first connecting member 310 and the second connecting member 320 achieve the limit in the three coordinate axis directions in the three-dimensional space, the box body and the end cover can be firmly connected. Only one buckle assembly 300 is provided between the box body and the end cover, that is, only one set of the first connecting member 310 and the second connecting member 320 is provided, and the box body and the end cover can be firmly connected together, simplifying the connection structure and assembly of the delivery box 10, and at the same time reducing the production cost of the delivery box 10.

[0063] In another alternative embodiment, the number of the buckle assemblies 300 can also be set to multiple. For example, in some cases, the box body of the delivery box 10 is designed to be larger. To balance the movement of the box body so as to stably and smoothly pull out the box body from the inside of the laundry treatment device, multiple buckle assemblies 300 can be provided to connect the box body and the end cover. Figure 2 and Figure 6 , the second component 200 includes a transition member 210, and the transition member 210 is connected to the second connecting member 320. Among them, the contact surface between the transition member 210 and the second connecting member 320 is a plane 211, and the first connecting member 310 is clamped between the clamping portion 322 and the plane 211.

[0064] By setting the contact surface between the transition member 210 and the second connecting member 320 as the plane 211, one end of the first connecting member 310 abuts against the plane 211, and the abutting effect between the two is better, enhancing the stability of the abutment between the first connecting member 310 and the second component 200. Moreover, the end surface of the first connecting member 310 abutting against the plane 211 can also be designed as a plane without being designed into a complex mating structure, further simplifying the overall structure of the buckle assembly 300.

[0065] Refer to Figure 5 and Figure 6As shown, taking the first component 100 as the box body and the second component 200 as the end cover as an example, the end cover includes a curved surface structure forming a handle groove. When there is not enough space on the end cover and the first connecting member 310 needs to abut against the area where the curved surface structure is located (that is, when the second connecting member 320 needs to be arranged on the curved surface structure), the transition member 210 can be connected to the curved surface structure, so that the first connecting member 310 abuts against the plane 211 of the transition member 210 instead of directly against the curved surface structure, improving the stability of the abutment between the first connecting member 310 and the end cover, ensuring the firm connection between the first connecting member 310 and the second connecting member 320, and thus enhancing the firmness of the connection between the box body and the end cover.

[0066] For more convenient assembly, in an embodiment, the first connecting member 310 is integrally formed with the first component 100, and the second connecting member 320 is integrally formed with the second component 200. Taking the first connecting member 310 arranged on the box body and the second connecting member 320 arranged on the end cover as an example, the first connecting member 310 is integrally formed with the box body, and the second connecting member 320 is integrally formed with the end cover. For example, the first connecting member 310 is integrally injection-molded with the box body, and the second connecting member 320 is integrally injection-molded with the end cover.

[0067] It should be noted that in this embodiment Figure 1 and Figure 2 the specific shapes and sizes of the first connecting member 310 and the second connecting member 320 shown are only for illustration, and certain deformation designs can be made according to specific connection and assembly requirements in actual applications.

[0068] Of course, in some other embodiments, the first component 100 and the second component 200 can also be other components in the dosing box 10, such as a negative pressure component (for generating negative pressure to suck the detergent), an electric control component, etc. The snap-fit assembly 300 can be considered for connecting all the components that need to be connected and combined on the dosing box 10.

[0069] Please refer to Figure 2 and Figure 6 and refer to Figure 7 for Figure 7 a partial structural schematic diagram of the second connecting member of the snap-fit assembly according to the embodiment of the present invention. A through groove 321b is further provided on the outer wall of the main body 321. The through groove 321b penetrates the outer wall of the main body 321 and communicates with the clearance groove 321a. The through groove 321b divides the main body 321 into a support portion 3211 and a connecting arm 3212. The connecting arm 3212 extends along the axial direction of the main body 321. One end of the connecting arm 3212 is connected to the support portion 3211, and the other end is a free end. The through groove 321b is located on both axial sides of the connecting arm 3212, so that both axial sides of the connecting arm 3212 are spaced from the support portion 3211. For the convenience of description, the end of the connecting arm 3212 connected to the support portion 3211 is defined as the first end 3212a.

[0070] like Figure 7 As shown, the through groove 321b separates the axial sides of the connecting arm 3212 from the support portion 3211, and the connecting arm 3212 is connected to the support portion 3211 only through the first end 3212a. Therefore, the portion of the connecting arm 3212 away from the first end 3212a will not be restrained by the support portion 3211. When the portion of the connecting arm 3212 away from the first end 3212a is acted upon by an external force, the connecting arm 3212 moves under the action of the force, causing the connecting arm 3212 to bend and deform along the direction of the force. After the force disappears, the connecting arm 3212 can return to its original state.

[0071] Please continue to refer to Figure 7 The clamping portion 322 is disposed on the connecting arm 3212 and is disposed near its free end. Then, the clamping portion 322 can elastically move following the bending deformation of the connecting arm 3212. When the connecting arm 3212 is bent and deformed into the air-avoiding groove 321a by an external force, the clamping portion 322 moves into the air-avoiding groove 321a.

[0072] Specifically, during the connection process between the first connector 310 and the second connector 320, the clamping portion 322 is squeezed by the hole wall of the first through hole 310a, and the clamping portion 322 transmits the squeezing force to the connecting arm 3212, so that the connecting arm 3212 is bent and deformed toward the inside of the air-avoiding groove 321a under the squeezing force, driving the clamping portion 322 to move into the air-avoiding groove 321a, so that the clamping portion 322 passes through the first through hole 310a. When the clamping portion 322 just passes through the first through hole 310a, the squeezing force of the first through hole 310a on the clamping portion 322 disappears, and at the same time, there is no obstruction of other structural parts outside the clamping portion 322, so that the connecting arm 3212 returns to its original state, driving the clamping portion 322 to move from the inside of the air-avoiding groove 321a to the outside of the main body 321, so that the clamping portion 322 abuts against the first connector 310.

[0073] Please refer to Figure 2 , Figure 6 and Figure 7 The clamping portion 322 includes a first surface 3221 and a second surface 3222, and the clamping portion 322 abuts against the first connector 310 through the first surface 3221. The second surface 3222 is located on the side of the first surface 3221 away from the first connector 310, wherein the second surface 3222 is the surface that first contacts the hole wall of the first via hole 310a when the clamping portion 322 passes through the first via hole 310a.

[0074] In one embodiment, the distance between the second surface 3222 and the first surface 3221 decreases from the end of the second surface 3222 close to the main body 321 to the end away from the main body 321. That is to say, the second surface 3222 and the first surface 3221 are not parallel, and the second surface 3222 can be an inclined surface or a curved surface. In one embodiment, the second surface 3222 is designed as an inclined surface.

[0075] Specifically, when the engaging portion 322 just enters the first through hole 310a, the hole wall of the first through hole 310a first contacts the second surface 3222. Since the second surface 3222 is an inclined surface, the resistance received when the engaging portion 322 enters the first through hole 310a can be reduced, making it easier for the engaging portion 322 to enter the first through hole 310a, which is beneficial for connecting the first connector 310 and the second connector 320. Moreover, as the engaging portion 322 enters the first through hole 310a, the hole wall of the first through hole 310a presses the second surface 3222 (the engaging portion 322), causing the connecting arm 3212 to gradually bend and deform. The extrusion force received by the connecting arm 3212 increases gradually rather than instantaneously, preventing the connecting arm 3212 from breaking or being damaged due to excessive force, and can extend the service life of the connecting arm 3212, thereby improving the connection reliability between the second connector 320 and the first connector 310.

[0076] To further enhance the firmness of the connection between the first connector 310 and the second connector 320, in one embodiment, the number of the engaging portions 322 can be multiple, and the multiple engaging portions 322 are arranged at intervals along the circumferential direction of the main body 321. For example, the multiple engaging portions 322 are evenly arranged along the circumferential direction of the main body 321.

[0077] This application also provides a laundry treatment device, which includes a dosing box 10 conceived based on any of the above embodiments. Among them, the laundry treatment device can be an electrical appliance such as a washing machine or a washer-dryer.

[0078] Since the laundry treatment device adopts all the technical solutions of the dosing box 10 in the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments.

[0079] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge scope of those of ordinary skill in the art.
