Description

Technical Field

[0001] The utility model relates to the technical field of small washing machines, in particular to a mini washing machine with a spin-drying barrel. Background Art

[0002] Conventional top-loading washing machines generally include two main cleaning components: a wave disc specifically used for washing, and a spin-drying barrel specifically used for drying. In order to achieve a better washing effect, the motion states of the wave disc and the spin-drying barrel generally need to be separated independently. For example, when washing, the wave disc rotates and the spin-drying barrel needs to be fixed, so that the clothes can be driven by the wave disc to produce friction and agitation with the barrel wall of the spin-drying barrel, thereby achieving a better washing effect. When the washing is completed and the spin-drying work needs to be done, the spin-drying barrel needs to rotate at a high speed in the same direction as the wave disc to drive out the water in the clothes through centrifugal force. In the existing traditional large washing machines, there is a component called a washing machine clutch to realize the synchronous or asynchronous operation of the washing machine wave disc and the spin-drying barrel. However, the clutch structure is relatively complex and has a large volume. For some smaller washing machines, the traditional clutch is difficult to apply. Therefore, most of the mini washing machines on the market currently have an integrated structure of the wave disc and the spin-drying barrel. When washing clothes, due to the effect of water buoyancy, it is difficult for the clothes to produce a large degree of friction and agitation with the barrel wall and the wave disc. Therefore, the mini washing machines of this structure generally have poor cleaning ability and low cleanliness. Summary of the invention

[0003] In order to solve the above problems, the utility model proposes a mini washing machine with a spin-drying drum, which realizes synchronous or asynchronous operation of the spin-drying drum and the wave plate by improving the mechanical structure of the washing machine, so that the mini washing machine can achieve a higher cleanliness and wash more cleanly.

[0005] Furthermore, it also includes a spin drying tub cover, which is rotatably arranged on the machine cover, used for covering the spin drying tub and can rotate synchronously with the spin drying tub.

[0006] Furthermore, the machine cover is provided with a driving motor or a locking structure for controlling the rotation of the spin drying tub cover.

[0010] As a preferred embodiment, the washing machine further includes a drying device, located outside the water tub, at the bottom, or on the machine lid. The drying device is provided with an air outlet for blowing hot air into the water tub.

[0013] Furthermore, the sterilization device is any one or a combination of an ultraviolet lamp, an electric water heating device, an electrolyzed water generator, and an ozone generator.

[0022] Figure 1 Shown is a spin-drying barrel mini washing machine according to an embodiment of the present utility model, which includes a housing 2, a machine cover 1, a water storage barrel 3, a spin-drying barrel 4, a wave disk 5 and a motor 6. Among them, the water storage barrel 3 is located inside the housing 2, the machine cover 1 is located at the top of the water storage barrel 3, the spin-drying barrel 4 is concentrically arranged inside the water storage barrel 3, the wave disk 5 is concentrically arranged at the inner bottom of the spin-drying barrel 4, the motor 6 is located at the outer bottom of the water storage barrel 3, and the rotating shaft of the motor 6 passes through the water storage barrel 3 and the spin-drying barrel 4 and is in transmission connection with the wave disk 5; it also includes a spin-drying barrel bearing 41, and the spin-drying barrel bearing 41 is arranged at the bottom of the spin-drying barrel 4, one side of which is connected to the spin-drying barrel 4 and the other side is connected to the water storage barrel 3, so that the spin-drying barrel 4 can freely rotate around the motor rotating shaft inside the water storage barrel 3. Since the diameter of the bearing is relatively large, arranging it at the bottom of the spin-drying barrel 4 can make the spin-drying barrel 4 receive more uniform force.

[0023] In some embodiments, it further includes a spin-dryer lid 9 which is rotatably arranged on the machine lid 1 and is used to cover the spin-dryer tub 4. When the washing machine is working, the spin-dryer lid 9 can rotate synchronously with the spin-dryer tub 4, making the rotation of the spin-dryer tub 4 more stable so that the clothes inside will not be thrown into the water storage tub 3.

[0024] Furthermore, the machine lid 1 is optionally provided with a driving motor which is in transmission connection with the spin-dryer lid 9 to drive the spin-dryer tub 4 to perform a rotational movement by driving the spin-dryer lid 41. Or a locking structure is arranged on the machine lid 1. By the operation and release of the locking structure, the spin-dryer lid 9 is controlled to be fixed or rotate freely, thereby controlling the spin-dryer tub 4 to be fixed or rotate, so as to achieve the effect of relative movement or synchronous movement with the wave disc 5, and then realize the two working conditions of cleaning and dehydration. The locking structure can be realized in the form of an electromagnetic push rod or a friction brake pad, etc., which is the prior art in the field. The specific implementation method can be queried from the prior art documents, and the present utility model does not make a specific introduction thereto.

[0025] Generally, the washing machine usually further includes a water inlet device 7, a drainage device 8, functional devices such as a water level detection device and a control circuit board. Among them, the motor 6, the water inlet device 7, the drainage device 8, the water level detection device, etc. are respectively electrically connected to the control circuit board.

[0026] In some embodiments, the spin-dryer mini washing machine further includes a counterweight block which is located on the tub body of the spin-dryer tub 4 or the spin-dryer lid 9. By increasing the weight, the inertia of the spin-dryer tub 4 or the spin-dryer lid 9 is increased, so that a larger speed difference is achieved between the wave disc 5 and the spin-dryer tub 4 during the clothes washing process, thereby increasing the overall cleaning strength.

[0027] As a preferred embodiment, the washing machine further includes a drying device which is located outside the water storage tub 3, at the bottom or on the machine lid 1. The drying device is provided with an air outlet which is electrically connected to the control circuit board to blow hot air into the water storage tub 3 to realize clothes drying.

[0028] As a preferred embodiment, the washing machine further includes a vibration sensor which is electrically connected to the control circuit board and is used to monitor the vibration of the washing machine.

[0029] In some embodiments, the washing machine further includes a sterilization device which is electrically connected to the control circuit board and is used to sterilize the inside of the water storage tub 2. The sterilization device can be any one of an ultraviolet lamp, an electric water heating device, an electrolyzed water generator, an ozone generator or a combination thereof.

[0030] The process of washing and dehydrating clothes using the mini washing machine of this embodiment is as follows: Turn on the washing machine switch. According to the set washing program, control the water inlet device 7 to open and inject water into the water storage bucket 3. When the water level reaches a certain height, the water level sensor senses and transmits a signal to the control circuit board, and the water injection stops. Then, the motor 6 drives the wave disk 5 to rotate, agitating the water and clothes in the bucket for washing. During the washing process, the wave disk 5 rotates forward and backward in a short time cycle, so that the drying bucket 4 always maintains a large speed difference with the wave disk 5 due to inertia, thereby achieving a high cleaning intensity. After washing for a certain period of time, the drainage device 8 is opened to drain the water in the water storage bucket 3, and then dehydration is carried out. The motor 6 starts slowly at a slower speed, drives the wave disk 5, and then drives the drying bucket 4 to start rotating, and then gradually increases the speed to achieve dehydration. At the same time, the vibration sensor continuously detects the shaking state of the washing machine to prevent the washing machine from shaking too much and causing danger.

[0031] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
