Description

Technical Field

[0001] The invention belongs to the field of washing equipment, and in particular relates to a washing equipment capable of forming two washing chambers. Background Art

[0002] With the development of economy and the improvement of people's living standards, washing machines have entered more and more families. Washing machines are also constantly being updated and improved, and people's requirements for the performance and appearance of washing machines have become higher and higher. At present, most of the pulsator washing machines sold on the market have only one pulsator. During the washing process, all the laundry can only move under the drive of the pulsator, executing a washing mode for washing clothes or shoes. Therefore, ordinary users have to buy both washing machines and shoe washing machines, which not only increases the cost of living but also occupies the household space.

[0003] In addition, the existing single-pulsator washing equipment has only one chamber, and all the laundry is located in the same chamber. During the washing process, clothes with hard materials may scratch other laundry, so they can only be washed separately, which wastes time and resources.

[0004] A Chinese patent with application number CN201410844259.4 discloses a shoe washing machine, comprising a water tub and an inner pulsator and an outer pulsator respectively arranged inside the water tub, wherein the inner pulsator is rotatably arranged at the center of the bottom of the water tub, and the outer pulsator is rotatably arranged at the periphery of the inner pulsator; the outer pulsator and the inner pulsator rotate in opposite directions in the washing state, a central brush is arranged on the inner pulsator, and a barrel wall brush is arranged on the inner wall of the water tub.

[0005] The shoe washing machine in the above scheme has two impellers, but the two impellers rotate in opposite directions to improve the cleaning effect. The shoe washing machine can only be used for washing shoes and cannot achieve two cleaning modes. In addition, the two impellers of the above shoe washing machine are nested, and the outer impeller is located inside the inner impeller, and two chambers cannot be formed to separate the items to be washed and wash them at the same time.

[0006] In view of the above technical deficiencies, the present invention is proposed. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a washing device which can realize two washing functions and form two washing chambers.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] A washing device comprising

[0010] Inner barrel;

[0011] The impeller shaft is provided with a telescopic shaft, and the telescopic shaft is telescopically arranged in the inner barrel along the axial direction;

[0012] The first impeller is mounted on the telescopic shaft and can be extended and lowered along with the telescopic shaft;

[0013] The telescopic axis has the following two states:

[0014] In the stretched state, the first impeller rises, and two washing chambers are formed in the inner tub, which are located above and below the first impeller respectively;

[0015] In the retracted state, the first impeller descends, and a washing chamber is formed in the inner tub, which is located above the first impeller.

[0016] By adopting the above solution, the user can set the telescopic shaft according to the needs, so that the washing device has different numbers of washing chambers, which can be used to wash different objects to be washed at the same time, providing convenience for the user, saving resources and time.

[0017] Further, an auxiliary washing component is provided below the first impeller, and the auxiliary washing component is provided at the bottom of the first impeller, and / or on the bottom wall of the inner barrel, and / or on the impeller shaft;

[0018] Preferably, the auxiliary washing component is a brush component, a water spray component, or a water stirring component.

[0019] By adopting the above solution, both the upper and lower sides of the first impeller can realize the washing function, so that when the washing device is in the state of two washing chambers, the two washing chambers can wash the objects to be washed, thereby improving the washing effect. In addition, the auxiliary washing parts have various forms and can be used to wash different objects to be washed, so that the washing device has different washing functions.

[0020] Furthermore, the auxiliary washing component is a second impeller installed on the impeller shaft, the second impeller is arranged close to the bottom of the inner barrel, and the distance between the second impeller and the first impeller is adjustable as the telescopic shaft extends and retracts.

[0021] By adopting the above solution, the washing device has two impellers, and the second impeller is located at the bottom of the inner barrel and does not change with the telescopic state of the telescopic shaft. During the washing process, both impellers can operate to drive the water flow to stir, thereby improving the cleaning effect.

[0022] Furthermore, the second impeller is provided with a brush;

[0023] Preferably, brushes are provided on both the upper and lower sides of the second impeller.

[0024] By adopting the above solution, the washing machine can wash both shoes and clothes, realizing multiple washing functions of the washing machine, and one machine has multiple uses. Users do not need to purchase both shoe washing machines and laundry machines at the same time, which not only saves the user's living costs, but also reduces the occupied area. In addition, brushes are provided on both the upper and lower sides of the second impeller. The brushes located on the lower side of the second impeller can clean small items to be washed that enter under the second impeller, so that items to be washed in multiple positions of the inner barrel can be cleaned.

[0025] In addition, when the two impellers rotate, the detergent between the two impellers is easier to dissolve. When a brush is provided on the second impeller, it is more conducive to the dissolution of the detergent, so that the detergent in the inner barrel is evenly dispersed, thereby improving the cleaning effect.

[0026] Furthermore, a third limiting portion and a fourth limiting portion are provided on the impeller shaft for limiting the position of the second impeller;

[0027] The fourth limiting portion is located below the third limiting portion;

[0028] Preferably, the third limiting portion and the fourth limiting portion are protruding structures arranged on the outer peripheral wall of the impeller shaft.

[0029] Further, the axial distance between the third limiting portion and the fourth limiting portion is greater than the axial length of the second impeller, and the second impeller can move axially between the third limiting portion and the fourth limiting portion.

[0030] By adopting the above solution, the second impeller can move up and down along the axial direction, collide with the objects to be washed, and improve the washing effect.

[0031] Furthermore, an inner barrel bottom cover is provided at the bottom of the inner barrel and is located below the second impeller.

[0032] By adopting the above solution, the second impeller can be prevented from colliding with the bottom wall of the inner barrel and related devices at the bottom during the up and down movement, thereby protecting the devices at the bottom of the inner barrel from being damaged.

[0033] Furthermore, the first impeller and the telescopic shaft are detachably connected.

[0034] By adopting the above scheme, it is convenient to put the laundry into the washing chamber between the two impellers. In addition, after the first impeller is disassembled, the telescopic shaft is retracted, and the washing device is similar to a pulsator washing machine; the telescopic shaft is stretched, and the washing device is similar to an agitator washing machine; the laundry is placed in the lower washing chamber, and then the first impeller is set on the telescopic shaft, the telescopic shaft is in a stretched state, and the laundry can be put into the upper and lower washing chambers for washing according to the cleaning requirements; if a larger washing chamber is required, the telescopic shaft can be retracted, and the washing device can be used in the same way as a pulsator washing machine. Therefore, the washing device can form a variety of washing modes, so that users can set the two impellers according to their needs to achieve different washing methods, which is convenient for users to use.

[0035] Furthermore, a first limiting portion and a second limiting portion are provided at the upper end of the telescopic shaft for limiting the first impeller, and the second limiting portion is located below the first limiting portion;

[0036] Preferably, the first limiting portion and the telescopic shaft are detachably connected;

[0037] Preferably, the first limiting portion is a shaft cover provided at the upper end port of the telescopic shaft.

[0038] Furthermore, the impeller shaft is sleeve-shaped; the telescopic shaft is movably arranged inside the impeller shaft and can move along the axial direction of the impeller shaft;

[0039] Preferably, a first connecting portion is provided on the telescopic shaft, and a second connecting portion is provided on the impeller shaft; the first connecting portion and the second connecting portion are matched and connected to relatively fix the telescopic shaft and the impeller shaft after being stretched.

[0040] By adopting the above solution, the telescopic shaft and the impeller shaft can be relatively fixed, so that when the telescopic shaft is in a stretched state, the inner barrel forms two fixed washing chambers.

[0041] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0042] 1. A telescopic shaft is installed on the impeller shaft of the washing device, and the user can set the telescopic shaft according to the needs so that the washing device has different numbers of washing chambers. In addition, an auxiliary washing component is installed under the first impeller, so that the two washing chambers have washing functions and can be used to wash different objects to be washed at the same time, which provides convenience for users and saves resources and time.

[0043] 2. The first impeller is detachable. After the first impeller is disassembled, it is convenient to put the items to be washed into the washing chamber below. In addition, users can set the two impellers and the telescopic shaft according to their needs. The washing equipment can form multiple washing modes and realize different washing methods, which is convenient for users to use.

[0044] 3. After the brush is set on the second impeller, the washing machine can wash both shoes and clothes, realizing multiple washing functions of the washing machine. Users do not need to buy shoe washing equipment and laundry equipment at the same time, which not only saves living costs for users, but also reduces the occupied area.

[0045] In addition, the detergent between the two impellers is easier to dissolve, especially when a brush is provided on the second impeller. Under the action of the water flow, the detergent in the inner barrel is evenly dispersed, thereby improving the cleaning effect.

[0046] 4. The second impeller can move up and down along the axis and collide with the objects to be washed. The bottom cover of the inner barrel is located below the second impeller, which can not only improve the cleaning effect but also protect the device at the bottom of the inner barrel from being damaged.

[0047] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0056] In the description of the present invention, it should be noted that the terms "upper", "inner", "outer", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0057] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] like Figures 1 to 4 As shown, a washing device of the present invention comprises an inner tub 1; a impeller shaft 42, on which a telescopic shaft 41 is installed, and the telescopic shaft 41 is telescopically arranged in the inner tub 1 along the axial direction; a first impeller 2 is installed on the telescopic shaft 41, and can be telescopically raised and lowered with the telescopic shaft 41; the telescopic shaft 41 has the following two states: in a stretched state, the first impeller 2 rises, and two washing chambers are formed in the inner tub 1, which are respectively located above the first impeller 2 and below the first impeller 2; in a contracted state, the first impeller 2 descends, and a washing chamber is formed in the inner tub 1, which is located above the first impeller 2.

[0059] A telescopic shaft 41 is installed on the impeller shaft 42 of the washing device of the present invention. The user can set the telescopic shaft 41 according to needs, and use the first impeller 2 installed on the telescopic shaft 41 to separate the chambers of the inner barrel 1, so that the washing device has different numbers of washing chambers, which can be used to wash different objects to be washed, providing convenience for users, saving resources and time.

[0060] like Figure 1 and Figure 2 As shown, a driving motor 6 is also provided at the bottom end of the washing device, and the lower end of the impeller shaft 42 is directly or indirectly connected to the driving motor 6. The driving motor 6 provides driving force for the impeller shaft 42 and the telescopic shaft 41, driving the impeller shaft 42 and the telescopic shaft 41 to rotate.

[0061] An auxiliary washing component is provided below the first impeller 2, and the auxiliary washing component is provided at the bottom of the first impeller 2, and / or on the bottom wall of the inner barrel 1, and / or on the impeller shaft 42; preferably, the auxiliary washing component is a brush component, a water spray component, or a water stirring component.

[0062] The auxiliary washing component located on the first impeller 2 of the present invention enables the upper side of the first impeller 2 to also realize the washing function, so that when the washing device is in the state of two washing chambers, the two washing chambers can wash the objects to be washed, thereby improving the washing effect. In addition, the auxiliary washing component has various forms and can be used to wash different objects to be washed, so that the washing device has different washing functions.

[0063] like Figure 1 and Figure 2 As shown, the auxiliary washing component is a second impeller 3 installed on the impeller shaft 42 . The second impeller 3 is arranged close to the bottom of the inner tub 1 , and the distance between the second impeller 3 and the first impeller 2 is adjustable as the telescopic shaft 41 is extended or retracted.

[0064] The first pulsator 2 and the second pulsator 3 are annular structures with a socket in the middle that matches the pulsator shaft 42 and the telescopic shaft 41. The shapes of the first pulsator 2 and the second pulsator 3 match to prevent the first pulsator 2 and the second pulsator 3 from rubbing against each other when the pulsator shaft 42 and the telescopic shaft 41 are rotating.

[0065] The first pulsator 2 and the second pulsator 3 can be arranged as required, and can be used to wash the same or different types of laundry when the laundry is placed in the washing chamber. The second pulsator 3 of the present invention is arranged on the pulsator shaft 42, and does not move with the telescopic state of the telescopic shaft 41. During the washing process, both pulsators can operate to drive the water flow to stir, thereby improving the washing effect.

[0066] like Figures 1 to 3 As shown, the second impeller 3 is provided with a brush 301; preferably, the second impeller 3 is provided with a brush 301 on both the upper and lower sides. Figure 1 and Figure 2 As shown, the structure of the first impeller 2 matches the structure of the second impeller 3 and the brush 301 , and is an arc surface structure.

[0067] By adopting the above scheme, the washing device can realize two washing functions, which can be used for washing shoes and clothes, realizing multiple washing functions of the washing device, one machine for multiple uses, and users do not need to purchase shoe washing equipment and laundry equipment at the same time, which not only saves the living cost for users, but also reduces the occupied area. In addition, the washing device can wash shoes and clothes, realizing two different washing functions. Furthermore, brushes 301 are provided on both the upper and lower sides of the second impeller 3. When some small pieces of clothing, including socks and insoles, enter the lower side of the second impeller 3, the brushes 301 located on the lower side of the second impeller 3 can also clean them, so that the objects to be washed located in multiple directions of the inner barrel 1 can be cleaned, thereby improving the cleaning effect.

[0068] The two washing chambers are connected. Figures 1 to 3 As shown, when the telescopic shaft 41 is in the retracted state, there is a gap between the first impeller 2 and the second impeller 3. When the second impeller 3 is provided with a brush 301, the detergent between the two impellers is more easily dissolved, and the two washing chambers are connected, so that the detergent in the inner barrel 1 is evenly dispersed, thereby improving the cleaning effect.

[0069] As an implementation scheme, Figure 4 As shown, a plurality of through holes are arranged on the pulsator disk of the first pulsator 2, which is the same as the pulsator disk of the pulsator washing machine, and water can flow into the upper and lower sides of the first pulsator 2 through the through holes to achieve communication between the two washing chambers. In addition, water can also flow through the jack at the central axis of the first pulsator 2 to achieve communication between the two washing chambers.

[0070] The impeller shaft 42 is provided with a third limiting portion 421 and a fourth limiting portion 422 for limiting the second impeller 3 ; the fourth limiting portion 422 is located below the third limiting portion 421 .

[0071] As a preferred solution, Figure 1 and Figure 2 As shown, the third limiting portion 421 and the fourth limiting portion 422 are protruding structures arranged on the outer peripheral wall of the impeller shaft 42.

[0072] The axial distance between the third limiting portion 421 and the fourth limiting portion 422 is greater than the axial length of the second impeller 3 , and the second impeller 3 can axially move between the third limiting portion 421 and the fourth limiting portion 422 .

[0073] By adopting the above solution, the second impeller 3 can collide and rub with the objects to be washed when it moves up and down between the third limiting portion 421 and the fourth limiting portion 422, which can further improve the cleaning effect. Especially when the second impeller 3 is used for washing shoes, since it is difficult for the brush 301 to completely extend into the shoes and wash the shoes in all directions, the second impeller 3 in this solution moves up and down to collide with the shoes, which can promote the brush 301 to extend into the shoes. In addition, it also makes the water flow inside the shoes continuously discharged and inflowed, thereby improving the flushing of the water flow to the inside of the shoes, thereby improving the cleaning effect.

[0074] Furthermore, the bottom of the inner barrel 1 is further provided with an inner barrel bottom cover 5, which is located below the second impeller 3. Figure 1 and Figure 2 As shown, the inner barrel bottom cover 5 is fixedly arranged above the fourth limiting portion 422 of the impeller shaft 42.

[0075] By adopting the above scheme, the inner tub bottom cover 5 is located below the second impeller 3. During the up and down movement of the second impeller 3, the bottom wall of the inner tub 1 can be prevented from directly colliding with the second impeller 3, and the related devices at the bottom of the inner tub 1 including the driving motor 6 can be protected from being hit, which can further protect the washing equipment.

[0076] The first impeller 2 and the telescopic shaft 41 are detachably connected.

[0077] By adopting the above scheme, the washing device of the present invention has the following four states:

[0078] The first state is: the telescopic shaft 41 is in a compressed state, the first pulsator 2 is arranged on the telescopic shaft 41, the first pulsator 2 and the second pulsator 3 are both located at the bottom of the inner tub 1, and the inner tub 1 has a washing chamber. In this state, the washing device is similar to a pulsator washing machine, but it is convenient to convert the state of the washing device, for example, from two washing chambers in which the telescopic shaft 41 is in a stretched state to one washing chamber in which the telescopic shaft 41 is in a retracted state, it is only necessary to retract the telescopic shaft 41.

[0079] The second state is: the telescopic shaft 41 is in a compressed state, the first pulsator 2 is detached, and the washing device only has the second pulsator 3, which is located at the bottom of the inner tub 1. In this state, the washing device is equivalent to a pulsator washing machine, only has one pulsator, and can achieve the same washing effect as a pulsator washing machine.

[0080] The third state is: the telescopic shaft 41 is in a stretched state, the first impeller 2 is arranged on the telescopic shaft 41 in the middle of the inner barrel 1, the second impeller 3 is located at the bottom of the inner barrel 1, and the inner barrel 1 has two washing chambers. In this state, the two washing chambers can wash different objects to be washed at the same time, and both can improve the washing effect. For example, the lower washing chamber is used to place clothes such as down jackets with strong buoyancy. Under the limit of the first impeller 2, the clothes can be completely soaked, thereby improving the washing effect; or the upper and lower washing chambers are used to place soft clothes and hard clothes respectively, which can prevent friction and scratches between clothes and is conducive to protecting clothes. Furthermore, the inner barrel 1 is divided into two washing chambers, which can wash different types of objects to be washed at the same time, and the objects to be washed that originally need to be washed twice can be washed once, saving washing time and resources and improving the practicality of the washing equipment.

[0081] The fourth state is: the telescopic shaft 41 is in a stretched state, the first impeller 2 is detached, and the washing device only has the second impeller 3, which is located at the bottom of the inner tub 1. In this state, the washing device is similar to a stirring washing machine, and the stretched impeller shaft 42 is equivalent to a stirring rod, which can improve the washing effect.

[0082] By adopting the above scheme, the washing device of the present invention can form multiple washing modes, so that the user can set the two impellers and the telescopic shaft 41 according to the needs to achieve different washing methods, which is convenient for the user to use. In addition, the first impeller 2 is detachable, which is convenient for putting the objects to be washed into the washing chamber between the two impellers.

[0083] The upper end of the telescopic shaft 41 is provided with a first limiting portion and a second limiting portion 412 for limiting the first impeller 2, and the second limiting portion 412 is located below the first limiting portion. Figure 2 As shown, after the telescopic shaft 41 is contracted, the second limiting portion 412 is clamped at the end of the impeller shaft 42, so as to relatively fix the telescopic shaft 41 and the impeller shaft 42.

[0084] Furthermore, the first limiting portion and the telescopic shaft 41 are detachably connected.

[0085] Preferably, if Figure 1 and Figure 2 As shown, the first limiting portion is a shaft cover 411 disposed at the upper end of the telescopic shaft 41 , and the outer diameter of the shaft cover 411 is greater than the outer diameter of the telescopic shaft 41 .

[0086] The second limiting portion 412 is formed by the telescopic shaft 41 and the first impeller 2. Specifically, an annular groove is provided on the outer peripheral wall of the telescopic shaft 41, and a convex rib cooperating with the annular groove is provided on the first impeller 2. Alternatively, the second limiting portion 412 is a protruding structure provided on the outer peripheral wall of the telescopic shaft 41, and the second limiting portion 412 and the first limiting portion limit the first impeller 2. The axial length of the first impeller 2 is the same as the axial distance between the shaft cover 411 and the second limiting portion 412, and the first impeller 2 is fixed between the shaft cover 411 and the second limiting portion 412.

[0087] The impeller shaft 42 is sleeve-shaped; the telescopic shaft 41 is movably disposed inside the impeller shaft 42 and can move along the axial direction of the impeller shaft 42 .

[0088] Furthermore, a first connecting portion is provided on the telescopic shaft 41, and a second connecting portion is provided on the impeller shaft 42; the first connecting portion and the second connecting portion are matched and connected to relatively fix the telescopic shaft 41 and the impeller shaft 42 after stretching (not shown in the figure).

[0089] As an implementation scheme, the first connecting portion is arranged on the outer wall of the telescopic shaft 41, and the second connecting portion is arranged on the inner wall of the impeller shaft 42. After being stretched, the telescopic shaft 41 and the impeller shaft 42 are snap-fitted to relatively fix the telescopic shaft 41 and the impeller shaft 42.

[0090] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced.
