[0052] The embodiments of the present application provide a washing equipment, comprising a machine body and a detergent feeding device.

[0053] The detergent feeding device is arranged on the water inlet waterway of the machine body. It can be understood that the detergent feeding device can be arranged at any appropriate position in the machine body.

[0054] Exemplarily, the machine body comprises a drum assembly having a laundry treatment cavity. In some embodiments, the drum assembly comprises an outer tub and an inner tub, and the space inside the inner tub is the laundry treatment cavity. It can be understood that, in some embodiments, the outer tub is used to hold water, and the inner tub holds water through the outer tub, i.e., the inner tub is a perforated inner tub, and the outer tub is a water holding tub. In other embodiments, the inner tub itself can hold water without the need of the outer tub, i.e., the inner tub is a non-perforated inner tub. It can be understood that, whether the inner tub is perforated or non-perforated, the inner tub rotates during the treatment of the laundry.

[0055] In other embodiments, the drum assembly can only have the inner tub without the outer tub, in which case the inner tub is a non-perforated inner tub.

[0056] In some embodiments, the rotation axis of the inner tub can be substantially along the vertical direction, i.e., the washing machine is a vertical axis washing machine, for example, a pulsator washing machine. In some embodiments, in the vertical axis washing machine, the rotation axis of the inner tub can have an angle of 0° with the vertical direction, or can have a small angle, for example, an angle less than 15°.

[0057] In other embodiments, the rotation axis of the inner tub can be substantially along the vertical direction, i.e., the washing machine is a vertical axis washing machine, for example, a pulsator washing machine. In some embodiments, in the vertical axis washing machine, the rotation axis of the inner tub can have an angle of 0° with the vertical direction, or can have a small angle, for example, an angle less than 15°.

[0058] The water inlet waterway refers to the general term of the water flow path. The water flow on the water inlet waterway flows through the detergent dispenser, and the water flow carries the detergent in the detergent dispenser to the drum assembly. In some embodiments, the mixed solution of the detergent and water discharged from the detergent dispenser directly flows into the laundry treatment cavity, and in other embodiments, the mixed solution of the detergent and water discharged from the detergent dispenser is guided to the drum assembly through a pipeline, for example, to the inner tub or to the space between the outer tub and the inner tub.

[0059] Please refer to FIG. 1, the detergent dispenser comprises a containing box assembly 1 and a detergent box 2.

[0060] Please refer to FIG. 2, the containing box assembly 1 comprises a box body 11, a cover assembly 12 and at least two first slide rail structures 13.

[0061] The box body 11 has a containing space 11a, and the first side of the box body 11 along the first direction is provided with a first opening 11b which is in communication with the containing space 11a.

[0062] Please refer to FIG. 1 to FIG. 3, the cover assembly 12 is arranged on the top of the box body 11.

[0063] It should be noted that the height direction is the direction shown in FIG. 1, which includes the direction from top to bottom and the direction from bottom to top.

[0064] Referring to FIGS. 2 and 4, the first slide rail structure 13 and the box body 11 are in a split structure. It can be understood that, in the embodiment of the present application, the split structure refers to two parts that are not integrally formed but are respectively independent parts. That is, the first slide rail structure 13 and the box body 11 are not integrally formed, so that the first slide rail structure 13 can be manufactured separately.

[0065] The first slide rail structure 13 is located in the accommodation space 11a, and the first slide rail structure 13 is connected with the cover assembly 12.

[0066] The at least two first slide rail structures 13 are arranged at intervals along a second direction. The first direction and the second direction intersect, for example, are substantially perpendicular.

[0067] It should be noted that the first direction can be the front-to-back direction of the washing device, and the second direction can be the left-to-right direction of the washing device; or the first direction can be the left-to-right direction of the washing device, and the second direction can be the front-to-back direction of the washing device.

[0068] Referring to FIG. 2, the detergent box 2 is pullably arranged in the accommodation space 11a and at least partially located between the two first slide rail structures 13, and the two first slide rail structures 13 are in sliding cooperation with the detergent box 2 to guide the movement of the detergent box 2 along the first direction. That is, the two first slide rail structures 13 determine the movement trajectory of the detergent box 2.

[0069] The detergent box 2 can contain fluid detergent and / or granular solid detergent, wherein the fluid detergent can be laundry detergent, softener, disinfectant, perfume, etc., and the granular solid detergent can be washing powder.

[0070] Exemplarily, the detergent box 2 has at least one accommodation groove for containing detergent. The number of accommodation grooves can be one, two, three, four, etc., and the number of accommodation grooves can be set according to specific washing needs. The present application does not limit here.

[0071] It can be understood that, before washing clothes, the user can pull at least a part of the detergent box 2 out of the accommodation box assembly 1, put detergent into the detergent box 2, and after completing the detergent putting, push the detergent box 2 into the accommodation box assembly 1.

[0072] In the related art, the slide rails are integrally formed on the side walls of the box body on opposite sides in the second direction, and the detergent box cooperates with the slide rails. When the box body is produced and manufactured, the mold used to form the box body will have a draft angle for easy demolding, which will cause the side walls of the box body on opposite sides in the second direction to have a draft angle. Specifically, in the direction along the first direction and close to the first opening, the two side walls of the box body extend in the direction away from each other due to the draft angle, and therefore, the slide rails on the two side walls also have an included angle, i.e., the two slide rails are not parallel, and the distance between the two slide rails is greater in the direction closer to the first opening, which causes the detergent box to easily shake during the process of being pulled out or pushed into the box body.

[0073] The detergent dispenser provided by the embodiments of the present application has a split structure of the first slide rail structure 13 and the box body 11, so that the box body 11 and the first slide rail structure 13 can be manufactured separately, the two first slide rail structures 13 are not affected by, for example, the draft angle in the first direction, which is beneficial to guarantee the straightness and parallelism of the two first slide rail structures 13 and is beneficial to improve the sliding cooperation between the detergent box 2 and the first slide rail structure 13, so as to reduce the possibility of shaking of the detergent box 2 during the process of being pulled out or pushed in and improve the user experience.

[0074] For example, referring to FIGS. 1-3, the cover assembly 12 includes a first cover 121, which has a split structure with the box body 11, and the first slide rail structure 13 is connected with the first cover 121.

[0075] That is, the first cover 121 and the box body 11 are not integrally formed, so that the first cover 121 can be manufactured separately.

[0076] It should be noted that the specific manner in which the first slide rail structure 13 and the first cover 121 are connected is not limited.

[0077] In some embodiments, referring to FIG. 4, the first slide rail structure 13 and the first cover 121 are of an integral structure. In this way, the first slide rail structure 13 can be manufactured together with the first cover 121, which can improve the production and manufacturing efficiency of the detergent dispenser while guaranteeing that the first slide rail structure 13 is not affected by, for example, the draft angle.

[0078] In other embodiments, the first slide rail structure 13 and the first cover 121 are of a split structure and are connected. In this embodiment, the connection between the first slide rail structure 13 and the first cover 121 can be welding, clamping, or bolt connection.

[0079] In some embodiments, referring to FIG. 2, the cover assembly 12 comprises a water inlet (not shown) and a water inlet cavity 12a, the water inlet is configured to guide a water source into the water inlet cavity 12a, and a bottom wall of the water inlet cavity 12a is provided with at least one through hole 12b configured to guide the liquid in the water inlet cavity 12a to the detergent box 2 arranged in the accommodation space 11a.

[0080] It should be noted that the number of through holes on the bottom wall of the water inlet cavity 12a can be one or multiple.

[0081] In this embodiment, the liquid in the water inlet cavity 12a enters the detergent box 2 arranged in the accommodation space 11a through the through hole 12b, so that the liquid is mixed with the detergent in the detergent box 2, and the mixed liquid is discharged from the detergent box 2 and flows to the bottom wall of the box body 11 and then flows out from the bottom edge of the first opening 11b.

[0082] In some embodiments, referring to FIGS. 2, 4 and 5, the cover assembly 12 comprises a plurality of flow guide ribs 12c arranged in the water inlet cavity, the plurality of flow guide ribs 12c divide the water inlet cavity into at least two sub-cavities that are not in communication with each other, and the bottom wall of each sub-cavity is provided with at least one through hole. It can be understood that the liquid entering the water inlet cavity 12a through the water inlet can flow along the flow guide ribs 12c to different sub-cavities, so as to flow into the detergent box 2 through different through holes, so as to guide the liquid to different accommodation grooves in the detergent box 2.

[0083] In some embodiments, referring to FIGS. 2 and 3, the cover assembly 12 comprises a second cover 122, the first cover 121 and the second cover 122 are stacked in the height direction of the detergent dispensing device, and the water inlet cavity 12a is formed between the first cover 121 and the second cover 122.

[0084] For example, the first cover 121 and the second cover 122 can be welded, bonded or the like. In this way, the sealing performance of the water inlet cavity 12a formed by the first cover 121 and the second cover 122 can be ensured, so as to reduce the possibility of liquid leakage in the water inlet cavity 12a from other places than the through hole 12b.

[0085] It should be noted that the connection relationship between the second cover 122 and the box body 11 is not limited.

[0086] In some embodiments, referring to FIG. 5, the second cover 122 and the box body 11 are in an integrated structure. It can be understood that the second cover 122 can be produced and manufactured together with the box body 11, so as to improve the connection strength and sealing performance between the box body 11 and the second cover 122.

[0087] In some embodiments, the second cover 122 is separate from the box body 11 and connected to the box body 11. It can be understood that the second cover 122 and the box body 11 can be manufactured separately, which reduces the complexity of the mold.

[0088] It should be noted that the relative position relationship between the first cover 121 and the second cover 122 is not limited.

[0089] In some embodiments, referring to FIGS. 2, 3 and 5, the first cover 121 is arranged on the side of the second cover 122 away from the accommodation space 11a, i.e., the first cover 121 is located on the top side of the second cover 122. The second cover 122 has an avoiding hole, and the first slide rail structure 13 passes through the avoiding hole 122a on the top side of the second cover 122 and extends into the accommodation space 11a. The avoiding hole 122a facilitates the assembly of the first slide rail structure 13. Specifically, the first cover 121 and the second cover 122 are connected after the first slide rail structure 13 passes through the avoiding hole 122a from top to bottom. In this way, even if the first cover 121 is located on the top side of the second cover 122, the first slide rail structure 13 can still be connected to the first cover 121 and extend into the accommodation space 11a.

[0090] In some embodiments, in the embodiment in which the first cover 121 is arranged on the side of the second cover 122 away from the accommodation space 11a, the second cover 122 and the box body 11 are integrated, for example, an integrally formed plastic part. In this embodiment, the accommodation space 11a is formed by the second cover 122 and the box body 11, and because the second cover 122 and the box body 11 are integrated, the water seepage and leakage performance at the junction of the second cover 122 and the box body 11 can be improved, and the reliability can be improved.

[0091] In some other embodiments, the first cover 121 is arranged on the side of the second cover 122 facing the accommodation space 11a, i.e., the first cover 121 is located on the bottom side of the second cover 122. In this embodiment, the accommodation space 11a can be formed by the second cover 122 and the box body 11, and the first cover 121 does not affect the sealing performance at the junction of the second cover 122 and the box body 11, which improves the water seepage and leakage performance of the second cover 122 and the box body 11, and improves the reliability.

[0092] In some embodiments, referring to FIG. 6, the detergent box 2 includes a main body part 21 and a second slide rail structure 22, and the main body part 21 is provided with the second slide rail structure 22 on both sides in the second direction.

[0093] The main body part 21 has structural strength and can provide support for the second slide rail structure 22, and the main body part 21 has an internal space for containing detergent.

[0094] In some embodiments, referring to FIG. 2, the detergent box 2 comprises a handle structure 23 arranged at one end of the main body 21 along the first direction and close to the first opening 11b. It can be understood that the handle structure 23 facilitates the user to apply force to the main body 21, and facilitates the user to push and pull the main body 21 through the handle structure 23, thereby improving the user's convenience. Exemplarily, the handle structure 23 is in the form of a plate, which covers the first opening 11b after the detergent box 2 is pushed into the accommodation space 11a.

[0095] It can be understood that the second slide rail structure 22 and the first slide rail structure 13 can be slidably matched to enable the main body 21 to move along the first direction. In this way, through the cooperation of the second slide rail structure 22 and the first slide rail structure 13, the sliding cooperation reliability between the detergent box 2 and the first slide rail structure 13 can be improved, the smoothness of the movement of the detergent box 2 along the first direction is further improved, and the user's experience is improved.

[0096] Exemplarily, one of the first slide rail structure 13 and the second slide rail structure 22 has a sliding groove, and the other is arranged in the sliding groove. It can be understood that the sliding groove can improve the stability of the sliding cooperation of the first slide rail structure 13 and the second slide rail structure 22, so as to reduce the possibility of derailment of the detergent box 2 during movement.

[0097] It should be noted that the above technical solutions include the following two kinds: first, the first slide rail structure 13 has a sliding groove, and the second slide rail structure 22 is arranged in the sliding groove; second, the second slide rail structure 22 has a sliding groove, and the first slide rail structure 13 is arranged in the sliding groove.

[0098] In other embodiments, the second slide rail structure 22 and at least a part of the main body 21 are in an integrated structure. In this way, the second slide rail structure 22 can be manufactured together during the manufacturing process of the detergent box 2, thereby reducing the number of parts and improving assembly efficiency. In addition, the integrated structure can improve the use reliability of the structure.

[0099] In some embodiments, referring to FIG. 6, the detergent box 2 is in an integrated structure, i.e., the second slide rail structure 22, the main body 21 and the handle structure are all in an integrated structure. In this way, the number of parts can be reduced, the assembly time can be saved, the structural strength of the detergent box 2 can be improved, the deformation of the detergent box 2 during extraction or insertion can be reduced, the smoothness of the movement of the detergent box 2 is ensured, and the service life of the detergent box 2 is improved.

[0100] It should be noted that the extension lengths of the first slide rail structure 13 and the second slide rail structure 22 are not limited. In some embodiments, the extension length of the first slide rail structure 13 along the first direction is not less than 50% of the extension length of the main body portion 21 along the first direction, for example, can be 60%, 70%, 80%, or 90%; and / or, the extension length of the second slide rail structure 22 along the first direction is not less than 50% of the extension length of the main body portion 21 along the first direction, for example, can be 60%, 70%, 80%, or 90%.

[0101] In this way, the first slide rail structure 13 and the second slide rail structure 22 have a larger matching length, have better guiding performance, can improve the range of movement of the detergent box 2 relative to the containing box assembly 1 along the first direction, facilitate the user to put detergent into the detergent box 2, and improve the use convenience of the user.

[0102] In some embodiments, referring to FIG. 6, a slide groove is formed in the first slide rail structure 13. The bottom surface of the second slide rail structure 22 is formed with a plurality of protrusions 22a arranged along the extension direction of the second slide rail structure 22, and the detergent box 2 is in sliding contact with the groove bottom wall of the slide groove through the protrusions 22a. It can be understood that, in the process of sliding cooperation between the second slide rail structure 22 and the first slide rail structure 13, the plurality of protrusions 22a on the second slide rail structure 22 can reduce the sliding friction therebetween, facilitate the sliding cooperation therebetween, and improve the efficiency of the sliding cooperation.

[0103] In some embodiments, referring to FIG. 4, the containing box assembly 1 further includes at least two first elastic arms 131 arranged on the first slide rail structure 13, the at least two first elastic arms 131 are arranged at intervals along the first direction, and the side of the second slide rail structure 22 away from the main body portion 21 is formed with a positioning protrusion 221 for elastically extruding cooperation with any one of the first elastic arms 131 along the second direction.

[0104] When the positioning protrusion 221 is not in contact with the first elastic arm 131, the pulling resistance of the detergent box 2 is relatively small, and when the positioning protrusion 221 moves to contact the first elastic arm 131 along with the detergent box 2, the positioning protrusion 221 extrudes the first elastic arm 131, so that the first elastic arm 131 elastically deforms in the second direction, and the first elastic arm 131 is abutted on the positioning protrusion 221 under the action of its own elastic force, at this time, the pulling resistance of the detergent box 2 is increased, which facilitates the user to feel the change of the resistance and know the position of the detergent box 2, and in addition, facilitates the detergent box 2 to be stably positioned at the current position and not to be easily shaken.

[0105] In some other embodiments, the detergent box 2 comprises at least two first elastic arms 131 arranged on the second slide rail structure 22, the at least two first elastic arms 131 are arranged in the first direction, the first slide rail structure 13 is provided with a positioning protrusion 221 along the second direction and towards the side wall of the side where the main body part 21 is located, the positioning protrusion 221 is used to elastically press fit with any one of the first elastic arms 131 in the second direction.

[0106] When the positioning protrusion 221 is not in contact with the first elastic arm 131, the pulling resistance of the detergent box 2 is relatively small, when the first elastic arm 131 moves to contact the positioning protrusion 221 along with the detergent box 2, the positioning protrusion 221 presses the first elastic arm 131, so that the first elastic arm 131 elastically deforms in the second direction, and the first elastic arm 131 is abutted on the positioning protrusion 221 under the action of its own elastic force, at this time, the pulling resistance of the detergent box 2 increases, which is convenient for the user to feel the change of resistance and know the position of the detergent box 2, in addition, it is also convenient to stabilize the detergent box 2 at the current position and not easy to shake.

[0107] The elastic arm (for example, the first elastic arm 131 described above, or the second elastic arm 132 described below) refers to a structure with one end as a connecting end and the other end as a free end, which can elastically deform. The specific material of the elastic arm is not limited, for example, it can be plastic, metal, etc.

[0108] Exemplarily, in the embodiments of the present application, the connecting end and the free end of the elastic arm are arranged along the first direction.

[0109] It should be noted that the specific connection relationship between the first elastic arm 131 and the first slide rail structure 13 is not limited.

[0110] In some embodiments, referring to FIG. 4, the first slide rail structure 13 and the first elastic arm 131 are an integral structure. In this way, the connection strength of the first elastic arm 131 and the first slide rail structure 13 can be improved, so as to improve the service life of the first elastic arm 131. In the embodiment in which the first elastic arm 131 is arranged on the second slide rail structure 22, the second slide rail structure 22 and the first elastic arm 131 are an integral structure.

[0111] In some embodiments, referring to FIG. 4, the first slide rail structure 13 has a notch 13a, the notch 13a penetrates the first slide rail structure 13 along the second direction, one end of the first elastic arm 131 is connected with the edge of the notch 13a along the first direction, and the other end is a free end. It can be understood that the free end of the first elastic arm 131 can move relative to the first slide rail structure 13 under the action of external force, when the positioning protrusion 221 presses the first elastic arm 131, the notch 13a can avoid the first elastic arm 131, so that the first elastic arm 131 can move to the extent that it is flush with the groove side wall of the first slide rail structure 13, in this way, the influence of the first elastic arm 131 on the assembly size of the first slide rail structure 13 can be reduced.

[0112] In addition, the notch 13a is located on the first slide rail structure 13, and the presence of the notch 13a does not affect the sealing of the box body 11.

[0113] In some embodiments, the detergent box 2 has a push-in position (see FIGS. 7 and 8) and a pull-out position (see FIGS. 9 and 10) in the accommodation space 11a. Referring to FIGS. 8 and 9, in the push-in position, the positioning protrusion 221 is elastically pressed against one of the first elastic arms 131 in the second direction. Referring to FIGS. 11 and 12, in the pull-out position, the positioning protrusion 221 is elastically pressed against another of the first elastic arms 131 in the second direction.

[0114] It should be noted that the pull-out position refers to the maximum position at which the detergent box 2 can be pulled out in the state shown in FIGS. 10 to 12 without completely detaching the detergent box 2 from the box body 11 assembly. The push-in position refers to the intended position of the detergent box 2 in the accommodation space 11a in the state shown in FIGS. 7 to 9.

[0115] It can be understood that in the push-in position and the pull-out position, the positioning protrusion 221 can be elastically pressed against different first elastic arms 131, so that the user can feel resistance in the push-in position and the pull-out position, thereby prompting the user to reach the relevant position, improving the user experience, and reducing the possibility of the user damaging the detergent box 2 by excessive force.

[0116] In some embodiments, referring to FIGS. 4, 14, and 15, the box assembly 1 includes a second elastic arm 132 disposed on the first slide rail structure 13, and the second elastic arm 132 has a protruding portion 132a formed on the side facing the main body portion 21. In the second direction and the direction close to the main body portion 21, the protruding portion 132a protrudes beyond the first elastic arm 131 or the positioning protrusion 221 disposed on the first slide rail structure 13.

[0117] It should be noted that the protruding portion 132a exceeds the first elastic arm 131 or the positioning protrusion 221 arranged on the first slide rail structure 13 in the second direction, which means that if the first elastic arm 131 is arranged on the first slide rail structure 13 and the positioning protrusion 1221 is arranged on the second slide rail structure 22, the protruding portion 132a exceeds the first elastic arm 131 in the second direction, and thus the interference degree between the first elastic arm 131 and the positioning protrusion 221 in the second direction is smaller than the interference degree between the protruding portion 132a and the positioning protrusion 221 in the second direction during the pulling stroke of the detergent box 2; if the first elastic arm 131 is arranged on the second slide rail structure 22 and the positioning protrusion 1221 is arranged on the first slide rail structure 13, the protruding portion 132a exceeds the positioning protrusion 1221 in the second direction, and thus the interference degree between the first elastic arm 131 and the positioning protrusion 221 in the second direction is smaller than the interference degree between the protruding portion 132a and the first elastic arm 131 in the second direction during the pulling stroke of the detergent box 2.

[0118] It should be noted that if the detergent box 2 wants to be completely separated from the containing box assembly 1, the detergent box 2 needs to overcome the resistance exerted by the protruding portion 132 and needs to bypass the protruding portion 132.

[0119] Since the protruding portion 132a exceeds the first elastic arm 131 or the positioning protrusion 221 arranged on the first slide rail structure 13 in the second direction and the direction close to the main body portion 21, when the detergent box 2 is pulled out to the pulled-out position, the protruding portion 132 exerts a greater resistance on the positioning protrusion 221 or the first elastic arm 131 arranged on the detergent box 2, and the detergent box 2 is not easy to be completely separated from the containing box assembly 1, which can also prompt the user that the detergent box 2 is about to exceed the pulled-out position, so as to reduce the possibility that the user mistakenly pulls out the detergent completely. If the detergent box 2 is not easy to be completely separated from the containing box assembly 1, the force needs to be continuously increased so that the positioning protrusion 221 or the first elastic arm 131 arranged on the detergent box 2 extrudes the protruding portion 132, forcing the protruding portion 132 to elastically deform away from the side of the detergent box 2 in the second direction, and then the detergent box 2 can be completely separated.

[0120] The various embodiments / implementation modes provided in the present application can be combined with each other without producing contradictions.

[0121] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
