Description

TECHNICAL FIELD

[0001] The present application belongs to the field of washing equipment, and particularly relates to a standby inner barrel and washing equipment. BACKGROUND

[0002] With the increasing pace of life, people have higher and higher requirements for washing equipment, and more hope that the same washing equipment has multiple washing functions, or can distinguish the laundry of different family members to prevent cross contamination. As for the washing machine, after washing clothes with high dirtiness, some stains may be left in the washing barrel, which may cause the clothes to become dirtier when washing clothes with low dirtiness. Or, when there are many members in the family, such as the elderly, children and pets, the stains on the clothes are different due to different bacteria carried by different members or different living and eating habits. If there is only one washing equipment in the family, the washing barrel needs to be cleaned before and after washing the clothes of different members. Or, the user wants to use the same washing equipment to wash clothes and shoes. Since the structure of the washing barrel of the washing machine is fixed and cannot be easily changed, the types of clothes that can be washed are also limited, which cannot meet the demand of a washing equipment with multiple washing functions.

[0003] A portable barrel of a washing machine is disclosed in Chinese Patent No. CN201910056126.3, which comprises a barrel body, a top ring, an impeller, a water circulation structure, a filter device and a pollution guide groove. The barrel body is detachably placed in the inner barrel of the washing machine. The top ring is arranged at the top opening of the barrel body. The impeller is rotatably arranged in the barrel body. The pollution guide groove is arranged on the inner wall of the barrel body along the height direction of the barrel body, and the barrel body is provided with a drain port corresponding to the top end position of the pollution guide groove. The water circulation structure is arranged between the impeller and the barrel body, and the filter device is arranged at the water flow end of the water circulation structure.

[0004] The portable barrel of the washing machine in the above-mentioned scheme can be disassembled and assembled with the washing machine, and can be used by a specific person. However, the barrel body is small in size and inconvenient to disassemble and assemble.

[0005] In view of the above technical defects, the present application is proposed. SUMMARY

[0006] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art, and to provide a standby inner barrel which is larger in volume and convenient to disassemble and assemble compared with the prior art.

[0007] To solve the above technical problems, the basic idea of the technical scheme of the present application is:

[0008] A standby inner barrel comprises,

[0009] The barrel body has a deformation structure at least near the upper end opening for changing the shape of the barrel body.

[0010] An installation part is arranged at the upper end opening of the barrel body and is used for matching connection with the device to be installed;

[0011] A washing part is arranged at the bottom of the barrel body and is used for realizing the washing function.

[0012] By adopting the above scheme, the barrel body can maximize the design volume and is easily loaded into the washing device through deformation; in addition, the installation part used for matching connection with the device to be installed is arranged at the opening of the barrel body, facilitating the dismounting operation.

[0013] Further, at least part of the peripheral wall at the upper end opening of the barrel body is made of a deformable material and is used for changing the shape of the opening;

[0014] Preferably, the outer diameter of the barrel body gradually decreases from the opening downwards;

[0015] Preferably, the barrel body is made of a deformable material.

[0016] By adopting the above scheme, the deformation mode of the deformable material is diversified, and deformation can be realized as long as external force is applied, facilitating the operation; the outer diameter of the barrel body gradually decreases from the opening downwards, that is, the outer diameter of the opening is the largest, as long as the barrel wall close to the opening can be loaded into the washing device, other parts can be easily loaded into the washing device. In addition, the installation part of the present application is located at the upper end opening of the barrel body, facilitating the connection of the barrel body and the washing device.

[0017] Further, the installation part comprises a clamping protrusion arranged on the opening and extending radially outward along the inner barrel;

[0018] Preferably, the clamping protrusion is provided with a plurality of clamping protrusions and is arranged at intervals along the circumference of the opening;

[0019] Preferably, the inner diameter of the barrel body gradually decreases from the opening downwards.

[0020] By adopting the above scheme, the clamping structure can be clamped with the device to be installed, facilitating the dismounting, a plurality of clamping protrusions are arranged at intervals along the circumference of the opening, and a water outlet can be formed at the gap to discharge the washing water; the inner diameter of the barrel body gradually decreases from the opening downwards, facilitating the water flow to rise along the barrel wall and be discharged outward during the dehydration process.

[0021] Further, it further comprises a supporting part arranged outside the bottom wall of the barrel body.

[0022] By adopting the above scheme, the bottom wall of the barrel body is prevented from contacting and rubbing with the device to be installed, causing damage to the barrel wall and shortening the service life of the barrel body.

[0023] Further, the washing part is arranged on the bottom wall of the barrel body and is of a telescopic structure and can be telescoped along the axial direction of the barrel body.

[0025] Furthermore, the washing section is corrugated and formed by local folds in the bottom wall of the tub body.

[0026] By adopting the above solution, the washing section is formed by local folds on the bottom wall of the tub body. During the process of extending and retracting along the axial direction of the tub body, it rubs against the items to be washed, similar to a washboard. Combined with the patting water flow, it completes the cleaning of the items to be washed.

[0027] Another object of the present invention is to provide a washing device having the above-mentioned spare inner tub, comprising a washing tub, wherein the tub body is detachably disposed inside the washing tub;

[0030] Furthermore, it also includes,

[0031] A pulsator is located at the bottom of the washing tub;

[0032] A rotating wheel, mounted on the impeller, is used to support the washing section extending upward along the axial direction of the tub body.

[0033] By adopting the above scheme, during washing, the impeller drives the washing section to extend along the axial direction of the tub body through the rotating wheel to complete the washing of the clothes to be washed; during spin-drying, the balance ring rotates at high speed along with the washing tub and the impeller, thereby driving the tub body to rotate at high speed to complete the spin-drying of the clothes to be washed.

[0034] Furthermore, the impeller is provided with a sliding part, and the rotating wheel is provided with a slide rail that matches the sliding part;

[0035] The impeller control sliding part slides along the slide rail to drive the wheel to extend and retract axially in the barrel body.

[0036] Furthermore, the sliding part includes a slide table, which is circumferentially disposed on the impeller and abuts against the end face of the slide rail. The slide table protrudes from the impeller surface at different heights along the circumferential direction.

[0037] The slide rail is arranged circumferentially on the rotating wheel, and the end face of the slide rail protrudes from the rotating wheel at different heights along the circumferential direction.

[0038] The slide table and the slide rail end face slide relative to each other in the circumferential direction, and the rotating wheel moves up and down relative to the impeller in the axial direction of the impeller.

[0039] By adopting the above scheme, in the process of rotating the sliding part along the circumference, the sliding part slides along the circumference relative to the chute end face, and the sliding part and the chute end face are respectively contacted at different heights, the height of the rotating wheel relative to the impeller changes, and the movement of the rotating wheel along the circumference is converted into the movement along the axis.

The washing part is a telescopic structure formed by local folding of the bottom wall of the barrel body, which is in contact and friction with the objects to be washed in the process of telescoping along the barrel body axis, similar to a washboard, and further cooperates with the water flow to complete the cleaning of the objects to be washed.

[0043] 3. The barrel body is connected with the balance ring, the balance ring rotates integrally with the washing barrel, and further drives the barrel body to rotate, and the rotating wheel drives the washing part to telescope along the barrel body axis, further improving the cleaning effect of the objects to be washed.

[0057] In order to make the purpose, technical scheme and advantages of the embodiments of the application more clear, the technical scheme in the embodiments will be described clearly and completely below with reference to the drawings of the embodiments of the application. The following embodiments are used to illustrate the application, but not to limit the scope of the application.

[0058] In the description of the application, it should be noted that the orientation or position relationship indicated by the terms "upper", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the application.

[0059] In the description of the application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0060] As Figure 1 andFigure 2 As shown, the present invention provides a spare inner tub 1, comprising: a tub body 11, having a deformable structure on the peripheral wall at least near the upper opening for changing the shape of the tub body 11; an installation part disposed at the upper opening of the tub body 11 for matching and connecting with the device to be installed; and a washing part 13 disposed at the bottom of the tub body 11 for realizing the washing function.

[0061] The tub body 11 of the present invention can be easily installed into the washing equipment by deformation. While keeping the dimensions of other parts of the tub body 11 unchanged, the volume of the tub body 11 can be appropriately increased during production and manufacturing, so as to maximize the design volume. In addition, the mounting part for matching and connecting with the equipment to be installed is provided at the port of the tub body 11, which facilitates disassembly and assembly operations.

[0062] The dimensions of the barrel body 11 can be adjusted by the following deformation methods:

[0063] At least two adjacent parts of the peripheral wall at least at the upper opening of the barrel body 11 are movably connected and can be folded and retracted in the circumferential direction.

[0064] Alternatively, at least a portion of the peripheral wall at the upper opening of the barrel body 11 may be made of a deformable material. By deforming the portion of the peripheral wall, the diameter of the upper opening of the barrel body 11 may be increased or decreased, thereby changing the shape of the opening.

[0065] As one implementation, the outer diameter of the tub body 11 gradually decreases from the opening downwards; that is, the outer diameter is largest at the opening. As long as the tub wall near the opening can be installed into the washing equipment, other parts can be easily installed into the washing equipment.

[0066] As a preferred embodiment, the peripheral wall of the tub body 11 is made of a deformable material. During the washing process, the tub body 11 rotates in both directions, and the peripheral wall can deform in multiple places to collide with the items to be washed, thereby improving the washing effect. The deformable material includes soft materials.

[0067] The tub body 11 of the present invention is a deformable structure. The mounting part is set at the port. Under the action of the weight of the tub body 11 itself and the weight of the water, the tub body 11 can be supported as a whole, preventing the top of the tub body 11 from detaching from the washing equipment.

[0068] like Figure 2 As shown, the mounting part includes a snap-fit ​​protrusion 12 disposed on the opening, the snap-fit ​​protrusion 12 extending radially outward to form a snap-fit ​​structure; preferably, there are multiple snap-fit ​​protrusions 12, spaced apart circumferentially along the opening. The snap-fit ​​structure can snap onto the equipment to be installed, making assembly and disassembly convenient. The multiple snap-fit ​​protrusions 12 are spaced apart circumferentially along the port, forming a water outlet at the gap, which can discharge washing water.

[0069] likeFigure 1 As shown, one end of the clamping convex 12 extends along the inner wall of the barrel body 11 from the port to the barrel bottom, forming a strip-shaped rib uniformly distributed on the inner wall of the barrel body 11 in the circumferential direction, used for contact and friction with the objects to be washed, improving the cleaning effect.

[0070] The clamping convex structure of the mounting portion is only a connection mode, and is not a limitation of the present application. Structures facilitating dismounting connection are within the protection scope of the present application.

[0071] The barrel body 11 is a non-porous barrel, and the inner diameter gradually decreases from the port along the axial direction downward. In the process of high-speed rotation of the barrel body 11, the water flow rises along the barrel wall and is discharged outward through the barrel port.

[0072] As shown in the accompanying drawings, Figure 2 As shown, the spare inner barrel 1 of the present application further comprises a supporting portion 14 arranged outside the bottom wall of the barrel body 11.

[0073] As an embodiment, the supporting portion 14 is an annular convex edge arranged on the bottom wall of the barrel body 11, close to the outer peripheral edge of the bottom wall of the barrel body 11, used for abutting against the bottom wall of the washing barrel 2 of the washing device, preventing the bottom wall of the barrel body 11 from contacting and rubbing against the bottom wall of the washing barrel 2 and causing damage to the barrel wall due to collision, and shortening the service life of the barrel body 11.

[0074] As shown in the accompanying drawings, Figure 1 and Figure 2 As shown, the washing portion 13 is arranged on the bottom wall of the barrel body 11 and has a corrugated structure capable of extending and retracting along the axial direction of the barrel body 11. In the process of extending and retracting along the axial direction of the barrel body 11, the washing portion 13 can drive the objects to be washed and the water flow to move up and down, so that the objects to be washed contact and rub against the washing portion 13, improving the washing effect of the objects to be washed.

[0075] The washing portion 13 is arranged at the center of the bottom wall of the barrel body 11, and the other parts of the bottom wall of the barrel body 11 are of a hard structure. The supporting portion 14 is arranged at the region of the bottom wall of the barrel body 11 corresponding to the hard structure.

[0076] The washing portion 13 is formed by local folding of the bottom wall of the barrel body 11 and rubs against the objects to be washed in the process of extending and retracting along the axial direction of the barrel body 11, similar to the effect of rubbing clothes on a washboard, cooperating with the beating of the water flow, and can improve the cleaning effect on the objects to be washed.

[0077] As shown in the accompanying drawings, Figures 3 to 8 Another object of the present application is to provide a washing device with the above-mentioned spare inner barrel 1, comprising a washing barrel 2, the barrel body 11 being detachably arranged in the washing barrel 2; a balance ring 3 arranged at the feeding port of the washing barrel 2; and a fitting portion arranged on the balance ring 3 and used for matching connection with the mounting portion of the barrel body 11.

[0078] The balance ring 3 is mounted on the drop port of the washing tub 2 and is fixed relative to the washing tub 2. The barrel body 11 is connected to the balance ring 3 through the assembly part and is fixed relative to the balance ring 3. The washing tub 2 can drive the barrel body 11 and the balance ring 3 to rotate.

[0079] Further, the assembly part on the balance ring 3 comprises a clamping groove 31 matched with the clamping convex 12 and uniformly distributed along the circumference of the balance ring 3. The water outlet is formed at the gap where the clamping groove 31 is connected with the clamping convex 12.

[0080] As shown in Figure 4 The washing device of the present application further comprises a pulsator 4 arranged at the bottom of the washing tub 2. A rotating wheel 5 is arranged at the top center of the pulsator 4 and is used to support the washing part 13 to extend axially upward along the barrel body.

[0081] As shown in Figure 3 and Figure 4 The center of the pulsator 4 is provided with a pulsator bushing 42. The washing tub 2 is connected with the driving device of the washing device. The pulsator 4 has a pulsator shaft 6. The pulsator 4 is fixedly connected with the pulsator shaft 6. The rotating wheel 5 is rotatably sleeved on the pulsator bushing 42. When the rotating wheel 5 rotates relative to the pulsator 4, the rotating wheel 5 can move axially upward and downward along the pulsator bushing 42.

[0082] When the washing device works, the driving device drives the pulsator 4 or the washing tub 2 to rotate, so that the rotating wheel 5 rotates relative to the pulsator 4. The rotating wheel 5 generates relative upward and downward movement. The gravity provided by the washing object and water in the standby inner tub 1 is used to realize the upward and downward extension of the washing part 13 and drive the water flow to wash the clothes.

[0083] Alternatively, when the driving device drives the pulsator 4 and the washing tub 2 to rotate respectively, for example, to rotate at different speeds in the same direction or to rotate in opposite directions, the rotating wheel 5 rotates relative to the pulsator 4. The rotating wheel 5 moves upward and downward relative to the pulsator 4. The gravity provided by the washing object and water in the standby inner tub 1 is used to realize the upward and downward extension of the washing part 13 and drive the water flow to wash the clothes. When the driving device drives the pulsator 4 and the washing tub 2 to rotate respectively, the washing tub 2 drives the balance ring 3 to rotate together with the standby inner tub 1. The balance ring 3 cooperates with the force provided by the upward and downward extension of the washing part 13 to contact, collide and pat the washing object at multiple angles, thereby further improving the cleaning effect of the washing object.

[0084] After the standby inner tub 1 is connected with the washing tub 2, the supporting part 14 abuts against the bottom wall of the washing tub 2 outside the pulsator 4.

[0085] As shown in Figure 5 and Figure 6As shown, the wave wheel 4 is provided with a sliding part 41, and the rotating wheel 5 is provided with a slide 52 matched with the sliding part 41; the wave wheel 4 controls the sliding part 41 to slide along the slide 52 to drive the rotating wheel 5 to stretch and retract along the axial direction of the wave wheel 4.

[0086] The sliding part 41 is arranged close to the wave wheel bushing 42 and surrounds the outer periphery of the wave wheel bushing 42.

[0087] Further, the sliding part 41 comprises a slide platform 411 arranged on the wave wheel 4 in the circumferential direction, and the side of the slide platform 411 facing the rotating wheel 5 is formed with a sliding surface abutting against the end surface of the slide 52; the slide platform 411 projects from the surface of the wave wheel 4 in the circumferential direction at different heights; the slide 52 is arranged on the rotating wheel 5 in the circumferential direction, and the end surface of the slide 52 projects from the rotating wheel 5 in the circumferential direction at different heights; the slide platform 411 and the end surface of the slide 52 slide relative to each other in the circumferential direction to realize the up-and-down movement of the rotating wheel 5 along the axial direction of the wave wheel 4.

[0088] As shown in the drawings, Figure 6 The slide 52 has a guide groove structure, and the groove width of the guide groove structure is not less than the width of the slide 52 to prevent the slide platform 411 from being covered by the slide 52 and the two cannot slide relative to each other.

[0089] Alternatively, the side of the slide 52 facing the slide platform 411 is a sliding surface structure, and the sliding surface of the slide 52 is in surface contact with the slide platform 411; the width of the sliding surface of the slide 52 depends on the friction coefficient of the slide 52 and the slide platform 411 to ensure that the friction force generated by the surface contact between the slide 52 and the slide platform 411 can cause the relative movement of the two.

[0090] Working principle: when the wave wheel 4 rotates, the slide platform 411 rotates relative to the slide 52, and the friction force generated between the two drives the slide 52 to rotate in the same direction, i.e. drives the rotating wheel 5 to rotate in the same direction as the wave wheel 4; the movement of the slide 52 relative to the slide platform 411 lags behind, and the different heights of the slide 52 and the slide platform 411 abut against each other in sequence, and the rotating wheel 5 moves up and down along the axial direction of the wave wheel 4; when the rotating wheel 5 moves upward, it drives the washing part 13 to stretch upward, and when the rotating wheel 5 moves downward, the washing part 13 retracts downward under the weight of the water and the washing objects in the barrel body 11.

[0091] As an embodiment, as shown in the drawings, Figure 5 The slide platform 411 is provided with two, which are centrally and symmetrically distributed with the wave wheel bushing 42 as the center. The height of the slide platform 411 projecting from the wave wheel 4 in the first direction gradually increases. As shown in the drawings, Figure 6 The slide 52 and the slide platform 411 are matched in shape, and the height of the slide 52 projecting from the rotating wheel 5 in the first direction gradually increases.

[0092] Further, as shown in the drawings, Figure 5As shown, the slide column 412 is arranged on the slide platform 411, and is located at one end of the slide platform 411 which protrudes from the highest position of the impeller 4. The slide column 412 can be inserted into the slide channel 52, and limits the movement of the slide platform 411 on the slide channel 52, so as to prevent the end of the slide platform 411 which protrudes from the highest position of the rotating wheel 5 from moving into the gap between the two slide platforms 411, thereby preventing the slide channel 52 from being stuck and unable to continue to move relative to the slide channel 52.

[0093] When the impeller 4 drives the slide platform 411 to move in the first direction, the slide column 412 moves from the low end to the high end of the slide channel 52, and the high end of the slide platform 411 abuts against the low end and the high end of the slide channel 52 in sequence, so as to drive the rotating wheel 5 to gradually move away from the impeller 4 in the axial direction. Conversely, when the impeller 4 moves in the second direction, the impeller 4 drives the slide platform 411 to move in the second direction, and the slide column 412 moves from the high end to the low end of the slide channel 52, and the high end of the slide platform 411 abuts against the high end and the low end of the slide channel 52 in sequence, so as to drive the rotating wheel 5 to gradually move close to the impeller 4 in the axial direction. The second direction is opposite to the first direction.

[0094] Alternatively, the two slide platforms 411 are integrally connected by extending the first end and the second end of the two slide platforms 411, and the first end and the second end of the two slide platforms 411 are smoothly connected to form a rounded structure. Correspondingly, the two slide channels 52 are integrally connected by extending the first end and the second end of the two slide channels 52, and the first end and the second end of the two slide channels 52 are smoothly connected to form a rounded structure. When the impeller 4 drives the rotating wheel 5 to rotate, the slide platform 411 moves relative to the end surface of the slide channel 52, and the slide platform 411 and the slide channel 52 are alternately matched and abutted at different heights, so as to drive the rotating wheel 5 to move up and down relative to the impeller 4 in the axial direction, regardless of the rotating direction. Further, the slide platform 411 is provided in plurality, and the plurality of slide platforms 411 are smoothly connected in a wave shape. Correspondingly, the slide channel 52 is provided in plurality, and the plurality of slide channels 52 are smoothly connected in a wave shape.

[0095] As shown in Figure 5 and Figure 6 The rotating wheel 5 comprises a cover 51, the slide channel 52 is arranged on the inner wall of the cover 51 and extends downward from the upper wall, a rotating wheel shaft sleeve 53 is arranged at the center of the cover 51 and extends downward from the top of the cover 51, and one end of the impeller sleeve 42 is inserted into the rotating wheel shaft sleeve 53 and movably connected with the cover 51. The slide channel 52 is arranged close to the rotating wheel shaft sleeve 53 and surrounds the outer periphery of the rotating wheel shaft sleeve 53.

[0096] As shown in Figure 3 and Figure 5 The impeller sleeve 42 is provided with a limiting structure 421 for limiting the upward axial movement of the rotating wheel 5.

[0097] As shown in Figure 7As shown, the limiting structure 421 is arranged at the upper end of the pulsator bush 42, which is an annular limiting rib, the rotating shaft sleeve 53 is two-sectioned, the inner diameter of the upper section is larger than that of the lower section, the outer diameter of the annular limiting rib is smaller than the inner diameter of the upper section of the rotating shaft sleeve 53 and larger than the inner diameter of the lower section of the rotating shaft sleeve 53, the limiting rib is arranged in the upper section of the rotating shaft sleeve 53, and the rotating shaft 5 can move up and down relative to the pulsator bush 42 but cannot be separated from the pulsator bush 42.

[0098] The rotating shaft 5 of the present application is in the form of a cover structure, which is equivalent to a pulsator cover and can cover the pulsator bush 42, and it can be understood that the rotating shaft 5 of the present application is formed by improving the structure of the pulsator cover, and no additional components are added relative to the pulsator 4 in the prior art, which will not cause a substantial increase in cost.
