Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a washing machine.

In an embodiment of the present application, a washing machine includes a housing and a drum disposed in the housing; wherein, casing one side is provided with the input mouth with the barrel intercommunication to supply the user to put in the clothing to the barrel.

Referring to fig. 1, the barrel includes an inner barrel 20 and an outer barrel 10 sleeved on the inner barrel.

It is understood that the washing machine 100 is provided with a driving device which is drivingly connected with the inner tub 20 to rotate the inner tub 20.

Because the inner cylinder 20 rotates and the outer cylinder 10 does not move, the inner cylinder 20 and the outer cylinder 10 are arranged at intervals in order to prevent the interference between the inner cylinder 20 and the outer cylinder 10; referring to fig. 1 and 2, the outer tub 10 includes a first tub wall 110 extending along an axial direction thereof, the inner tub 20 includes a second tub wall 210 extending along the axial direction thereof, a water passing space is formed between the first tub wall 110 and the second tub wall 210, the second tub wall 210 is provided with water passing holes (not shown) communicated with the water passing space, and the outer tub 10 is further provided with a drainage structure communicated with the water passing space, so that after each cleaning process of the washing machine 100 is finished, water and dirt in the inner tub 20 flow into the water passing space through the water passing holes and are drained through the drainage structure.

As can be understood, since the input opening of the drum washing machine 100 is disposed at the front of the housing, that is, the axis of the drum is horizontally disposed, in order to prevent the water and the laundry in the inner drum 20 from flowing out, the outer drum 10 further includes a first sidewall 120 connected to one side of the first drum wall 110 and a second sidewall connected to the other side of the first drum wall 110, wherein the first sidewall 120 is disposed toward the input opening of the washing machine 100, and the first sidewall 120 has a first opening corresponding to the input opening; similarly, the inner tub 20 further includes a third sidewall 220 connected to one side of the second tub wall 210 and a fourth sidewall connected to the other side of the second tub wall 210, wherein the third sidewall 220 faces the input opening of the washing machine 100, and the third sidewall 220 has a second opening corresponding to the input opening.

The clothes usually carry impurities such as lint, fiber and even paper scrap, and in the process of draining water after the washing machine 100 is washed, the impurities enter the water passing space through the water passing holes along with water flow and are discharged through the drainage structure, and the impurities have certain adhesion, and the impurities are adhered to the inner surface of the first cylinder wall 110 (namely the inner wall of the outer cylinder 10) in the draining process, are retained for a long time and accumulated in a humid environment, so that mildew is easily bred, the clothes are polluted and smelly, and the use experience of a user is influenced.

In order to solve the above problem, in the embodiment of the present application, please refer to fig. 3, fig. 4, fig. 5 and fig. 6 in combination, the washing machine 100 further includes a cleaning device 30, the cleaning device 30 includes a cleaner 31 and a knob structure 32, the cleaner 31 is rotatably mounted on the outer side of the second cylinder wall 210, and the cleaner 31 extends along the axial direction of the inner cylinder 20; the knob structure 32 is connected to one end of the cleaner 31, the knob structure 32 can rotate under the action of an external force to drive the cleaner 31 to rotate and switch between an avoiding state and a working state, and when the cleaner 31 is in the avoiding state, the cleaner 31 and the outer surface of the first cylinder wall 110 are arranged at intervals; when the cleaner 31 is in operation, the cleaner 31 contacts the inner surface of the first cylinder wall 110.

Specifically, when a user needs to clean the inner surface of the first cylinder wall 110, the knob structure 32 is manually rotated, the cleaner 31 is driven by the knob structure 32 to rotate to contact with the inner surface of the first cylinder wall 110, as shown in fig. 5 and 6, the cleaner 31 is in an operating state, a cleaning mode of the washing machine 100 is selected, the inner cylinder 20 is driven by the driving device to rotate, the cleaner 31 rotates along with the inner cylinder 20, so that the cleaner 31 is in frictional contact with each part of the inner surface of the first cylinder wall 110, and the accumulated impurities on the inner surface of the first cylinder wall 110 are scraped off and discharged through the drainage structure of the outer cylinder 10.

After the cleaning is completed, the knob structure 32 is manually rotated again, and the cleaner 31 is rotated to be spaced apart from the inner surface of the first wall 110 by the knob structure 32, as shown in fig. 4, so that the cleaner 31 is prevented from contacting the inner surface of the first wall 110 when the cleaning is not required to be performed, the cleaner 31 is prevented from colliding with the outer tub 10 when the inner tub 20 is rotated at a high speed (for example, in a dehydration mode or a tub drying mode), the operation stability of the washing machine 100 is ensured, and the cleaner 31 is prevented from being damaged.

It is understood that, in order to enable the user to provide a force to drive the knob structure 32 to rotate, referring to fig. 1, the first sidewall 120 is provided with a through hole 121 extending therethrough, and the knob structure 32 is disposed opposite to the through hole 121, so that the hand of the user can contact the knob structure 32 through the through hole 121 (or contact the knob structure 32 through the through hole 121 by using a tool).

It should be noted that, because the inner cylinder 20 is rotatable, that is, the position of the knob structure 32 is changed, and the outer cylinder 10 is stationary, that is, the position of the through hole 121 is stationary, the arrangement of the knob structure 32 relative to the through hole 121 here means: no matter where the knob structure 32 is located in the resting state, the knob structure 32 can be rotated to be opposite to the through hole 121 all the time.

Specifically, to rotate the knob structure 32 to be opposite to the through hole 121, the radial distance from the center of the knob structure 32 to the axis of the inner cylinder 20 is equal to the radial distance from the center (or center line) of the through hole 121 to the axis of the inner cylinder 20, i.e., the rotation path of the rotating structure coincides with the center (or center line) of the through hole 121. When a user needs to clean the inner side wall of the outer cylinder 10, if the knob structure 32 does not correspond to the position of the through hole 121, the user can manually rotate the inner cylinder 20 until the inner cylinder 20 rotates until the knob structure 32 corresponds to the position of the through hole 121, so that the user can drive the knob structure 32 to rotate to drive the cleaner 31 to rotate to a working state.

The shape of the via hole 121 may be various, for example, the via hole may be a circular hole, a square hole, an arc hole, and the like, and the specific shape and size of the via hole 121 are not limited herein, and the via hole 121 is provided by taking the arc hole as an example in the drawings in the embodiment of the present application, but the present application is not considered to be limited thereto.

Because the remaining impurities on the inner wall of the outer tub 10 (the inner surface of the first tub wall 110) are formed by cleaning for multiple times and gradually accumulating, the cleaning times of the inner surface of the first tub wall 110 do not need to be too frequent (for example, the cleaning times can be once per week), in the embodiment of the present application, by setting the knob structure 32, when a user needs to clean the inner surface of the first tub wall 110, the knob structure 32 is manually rotated to drive the cleaner 31 to rotate between the avoiding state and the working state, compared with the case that the cleaner 31 is driven to rotate by setting the electric driving structure, the electric driving structure is omitted, the overall volume of the cleaning device 30 is prevented from being too large, the cleaning device 30 is prevented from occupying too much space and needing to increase the outer diameter of the outer tub 10, and thus the volume of the casing of the washing machine 100 is prevented from being increased; and since the electric driving structure is omitted, the corresponding production cost of the washing machine 100 can be saved, and a control program of the electric driving structure does not need to be designed, thereby simplifying the control program of the washing machine 100.

The washing machine 100 of the embodiment of the application comprises a cleaning device 30, the cleaning device 30 comprises a cleaner 31 and a knob structure 32, the cleaner 31 is rotatably installed outside the second cylinder wall 210, the cleaner 31 extends along the axial direction of the inner cylinder 20, the knob structure 32 is connected to one end of the cleaner 31, the knob structure 32 can rotate under the action of external force to drive the cleaner 31 to rotate and switch between an avoiding state and a working state, when the cleaner 31 is in the avoiding state, the cleaner 31 is arranged at a distance from the inner surface of the first cylinder wall 110, and the influence on the working stability of the washing machine 100 caused by the contact between the cleaner 31 and the inner surface of the first cylinder wall 110 when the washing machine 100 performs normal washing work is prevented; when the cleaner 31 is in a working state, the cleaner 31 contacts with the inner surface of the first cylinder wall 110, and meanwhile, in the rotating process of the inner cylinder 20, the inner cylinder 20 drives the cleaner 31 to rotate together, so that the cleaning part 312 is in friction contact with the inner surface of the first cylinder wall 110, thereby scraping the retained impurities on the inner surface of the first cylinder wall 110, preventing the impurities from being retained on the inner surface of the first cylinder wall 110 for a long time to breed mold, preventing clothes from being polluted in the cleaning process, and improving the use experience of users.

Since the cleaner 31 is rotated and switched between the working state and the avoiding state, that is, the cleaner 31 needs a certain rotating space, if the cleaner 31 is directly installed outside the second cylinder wall 210, the inner diameter of the outer cylinder 10 needs to be increased, and in order to avoid increasing the volume of the outer cylinder 10 and increasing the overall volume of the washing machine 100, referring to fig. 2, in the embodiment of the present application, the outer side wall of the second cylinder wall 210 is provided with a groove 211, the groove 211 extends axially along the inner cylinder 20, and the cleaner 31 is rotatably installed in the groove 211.

Thus, the groove 211 is formed in the outer side of the second cylinder wall 210, and the cleaner 31 is rotatably installed in the groove 211, so that the cleaner 31 can be prevented from occupying too much water passing space, the cleaner 31 can be installed on the premise of not changing the whole volume of the shell, and the inner surface of the first cylinder wall 110 can be cleaned.

Since the first cylinder wall 110 is generally a sheet metal part, the first cylinder wall 110 is inconvenient to process a rotary connection structure for installing the cleaner 31, and in order to facilitate the production and processing of the first cylinder wall 110, in the embodiment of the present application, referring to fig. 3, the cleaning device 30 further includes two installation bases 33, the two installation bases 33 are respectively connected to two opposite sides of the groove 211 along the axial direction of the inner cylinder 20, and the cleaner 31 is rotatably installed in the groove 211 through the two installation bases 33.

Therefore, in the embodiment of the present application, the cleaner 31 is rotatably connected to the mounting seat 33, and then the mounting seat 33 and the cleaner 31 are integrally connected and fixed to the first cylinder wall 110, that is, in the embodiment of the present application, the cleaner 31 is indirectly connected to the first cylinder wall 110, and a complex rotational connection structure does not need to be processed on the first cylinder wall 110, so that the production and processing process of the first cylinder wall 110 is simplified, the production of the first cylinder wall 110 is facilitated, and the production efficiency of the first cylinder wall 110 is not affected.

Referring to fig. 7 and 8, in the embodiment of the present disclosure, the mounting base 33 includes a main body 331 and a positioning post 333, the positioning post 333 is protruded from a side of the main body 331 facing a bottom of the groove 211, the bottom of the groove 211 is provided with a positioning hole 212, and the positioning post 333 is inserted into the positioning hole 212.

It can be understood that, by providing the positioning column 333 to be inserted into and matched with the positioning hole 212, the mounting seat 33 can be quickly positioned, and the mounting efficiency of the cleaning device 30 is improved.

Since the inner cylinder 20 is rotatable, in order to prevent the mounting seat 33 from falling from the groove 211, the mounting seat 33 and the groove 211 need to be connected and fixed, please refer to fig. 7 and 8, in the embodiment of the present application, the mounting seat 33 further includes a connecting portion 334, the connecting portion 334 is protruded at one side of the body 331, and the connecting portion 334 is screwed with the groove 211 through a screw.

Specifically, as shown in fig. 8, a first connection hole 213 is formed at the bottom of the groove 211, step grooves 214 are further formed at two ends of the groove 211 along the axial direction of the inner cylinder 20, the step grooves 214 are arranged lower than the groove 211, a second connection hole 215 is formed in a groove wall of the step groove 214 close to one side of the groove 211, a connection part 334 is inserted into the first connection hole 213, a second threaded hole 335 is formed in one side of the connection part 334 facing the second connection hole 215, and a screw passes through the second connection hole 215 and is screwed with the second threaded hole 335 of the connection part 334, so that the mounting base 33 is fixedly connected with the groove 211.

Referring to fig. 9 and 10, in the present embodiment, the cleaner 31 includes a rotating shaft 311, the rotating shaft 311 has a first end 311a and a second end 311b opposite to each other, the first end 311a is screwed with one of the mounting seats 33, and the second end 311b is rotatably connected with the other mounting seat 33.

It can be understood that, by screwing the first end 311a of the rotating shaft 311 with the mounting seat 33, the cleaner 31 can be kept in a avoiding state when the washing machine 100 performs normal washing operation due to certain self-locking capability of the screw thread, so as to prevent the cleaner 31 from contacting with the inner surface of the first cylinder wall 110 when the cleaner 31 is vibrated and automatically rotated, and avoid affecting the stability of the normal operation of the washing machine 100; furthermore, under the self-locking force of the screw thread, the cleaner 31 can be prevented from rotating under a small external force, so that when a user cleans the inner surface of the first cylinder wall 110, the cleaner 31 can be ensured to be in a working state, and the cleaner 31 can be prevented from rotating under the friction force of the inner surface of the first cylinder wall 110 to influence the cleaning effect (during the cleaning process of the cleaner 31, the cleaner 31 is in friction contact with the inner surface of the first cylinder wall 110, the first cylinder wall 110 generates resistance to the cleaner 31, and the resistance makes the cleaner 31 have a tendency of rotating in a direction opposite to the rotation direction of the inner cylinder 20, and because the inner surface of the first cylinder wall 110 is generally smooth, the resistance to the cleaner 31 is small and is not enough to overcome the self-locking force of the screw thread, so that the cleaner 31 can be prevented from rotating in the working state).

Referring to fig. 7, 9 and 10, in the embodiment of the present application, one of the mounting seats 33 is provided with a first threaded hole 332 for screwing the first end 311a, and correspondingly, the outer peripheral wall of the first end 311a is provided with a first threaded portion 313, and the first threaded portion 313 is in threaded connection with the first threaded hole 332.

In order to ensure that the cleaner 31 is kept in the avoiding state or the working state, the first threaded portion 313 and the first threaded hole 332 may preferably adopt a threaded structure with strong self-locking capability, for example, the thread profile of the drawings in the embodiment of the present application is triangular.

The first threaded hole 332 is a through hole, so that the first end 311a can pass through the first threaded hole 332 to be connected with the knob structure 32. In this way, the present embodiment connects the knob structure 32 to the first end 311a, so that the knob structure 32 is close to the first threaded portion 313, thereby facilitating the user to drive the knob structure 32 to rotate.

Specifically, in the embodiment of the present application, the knob structure 32 is exemplified by a cross screw, and when a user needs to clean the inner surface of the first cylinder wall 110, the cross screwdriver can be held by a hand and is passed through the through hole 121 to contact the cross screw, and the cross screwdriver is rotated, and at this time, the cross screwdriver applies a rotation torque to the cross screw, so as to drive the first thread portion 313 and the first thread hole 332 to perform a helical transmission, and thus drive the rotating shaft 311 to rotate integrally. Of course, the specific structure and shape of the knob structure 32 can be varied, and the structure shown in the drawings of the present application is an embodiment of the present application and should not be considered as limiting the present application.

Referring to fig. 10, in the embodiment of the present application, the cleaner 31 further includes a cleaning portion 312, the cleaning portion 312 is connected to the outer peripheral wall of the rotating shaft 311 and extends along the axial direction of the rotating shaft 311, and the cleaning portion 312 partially covers the outer peripheral wall of the rotating shaft 311.

The cleaning portion 312 may be a brush, a cotton cloth, or the like. The material of the cleaning portion 312 is preferably flexible so that the cleaning portion 312 can be flexibly deformed when contacting the inner surface of the first cylinder wall 110 to ensure that the cleaning portion 312 is sufficiently and effectively contacted with the inner surface of the first cylinder wall 110.

It can be understood that, by partially covering the cleaning portion 312 on the outer peripheral wall of the rotating shaft 311, that is, the cleaning portion 312 does not surround the entire outer peripheral wall of the rotating shaft 311, that is, there are a portion where the cleaning portion 312 is disposed and a portion where the cleaning portion 312 is not disposed on the outer peripheral wall surface of the rotating shaft 311, when the cleaner 31 is in the retracted state, the rotating shaft 311 is rotated until the portion where the cleaning portion 312 is not disposed faces the inner surface of the first cylinder wall 110 (at this time, the portion where the cleaning portion 312 is disposed on the rotating shaft 311 is opposite to the inner surface of the first cylinder wall 110), so that the cleaner 31 is spaced from the inner surface of the first cylinder wall 110, and the cleaner 31 is prevented from contacting the inner surface of the first cylinder wall 110.

Specifically, in the embodiment of the present application, the cleaning portion 312 is exemplified by a brush, and the brush is connected to the outer peripheral wall of the rotating shaft 311 in a "radial manner" such that the cross section of the whole brush is substantially in a fan shape, so as to increase the contact area between the brush and the inner surface of the first cylinder wall 110 and ensure the cleaning effect of the cleaner 31 on the inner surface of the first cylinder wall 110. Wherein, in order to ensure that the brush does not contact with the inner surface of the first cylinder wall 110 when the cleaner 31 is in the avoiding state, the central angle of the fan shape is less than or equal to 180 degrees.

Because the cleaner 31 is rotatably installed on the outer side of the first cylinder wall 110, a user cannot observe a specific position of the cleaning portion 312 when driving the cleaner 31 to rotate, and in order to facilitate the user to quickly determine whether the cleaning portion 312 is rotated in place, in the embodiment of the present application, referring to fig. 10, the knob structure 32 is provided with a first indication portion 321, the mounting seat 33 is provided with a second indication portion 336 and a third indication portion 337, the second indication portion 336 and the third indication portion 337 are arranged oppositely, and when the knob structure 32 drives the cleaner 31 to rotate to a working state, the first indication portion 321 corresponds to the second indication portion 336; when the knob structure 32 rotates the cleaner 31 to the retracted state, the first indicating portion 321 corresponds to the third indicating portion 337.

In the embodiment of the present application, with a plane passing through the midpoint of the cleaner 31 and perpendicular to the axis of the cleaner 31 as a reference plane, the orthographic projection of the first indicating part 321 on the reference plane is located in the middle of the orthographic projection of the cleaning part 312 on the reference plane.

It can be understood that the orthographic projection of the first indicating part 321 on the reference plane is located in the middle of the orthographic projection of the cleaning part 312 on the reference plane, that is, the first indicating part 321 corresponds to the position of the cleaning part 312, and the position where the first indicating part 321 faces is the position of the cleaning part 312. Thus, a user can quickly determine the position of the cleaning part 312 relative to the inner surface of the first cylinder wall 110 by the pointing direction of the first indicating part 321, so that the user can be ensured to rotate the cleaning part 312 to just contact or back to the inner surface of the first cylinder wall 110 under the condition that the user cannot directly observe the cleaning part, and the user is prevented from rotating by mistake.
