Description

Technical Field

[0001] This utility model relates to the field of household washing machine technology, and in particular to a fully automatic mini washing machine with a detachable drum. Background Technology

[0002] Washing machines have become an indispensable household appliance in modern families, bringing great convenience to people's lives. Because washing machines are frequently in contact with water, their internal structure is constantly in a humid and hot environment, making them prone to bacterial and fungal growth. Over the years, dirt tends to accumulate in the inner layers of the washing machine drum, causing the machine's hygiene to deteriorate. Therefore, people are paying increasing attention to the cleanliness of the washing machine's interior.

[0003] Currently, among the existing technologies for detachable drum fully automatic washing machines, one type is based on the structure of traditional fully automatic washing machines. This type of design relies on the complex clutch structure of traditional washing machines, where the inner shaft of the clutch connects to the impeller to achieve its rotation, and the outer shaft connects to the spin-dry tub to achieve its rotation. For example, patent number CN201510309877.3 describes a detachable drum impeller washing machine. This patent uses a pressure plate structure to confine the inner drum within the outer tub. When the inner drum needs cleaning, the pressure plate can be opened to remove it for cleaning. However, in actual operation, after opening the pressure plate, the impeller screw still needs to be unscrewed to remove the impeller before the inner drum can be easily removed. In this solution, the impeller and the inner drum are still two independent components that need to be disassembled separately before the inner drum can be completely removed. This is still not convenient enough. In addition, this type of washing machine uses a traditional clutch structure, which is complex, large, and has high manufacturing costs, making it difficult to meet the market demand for miniaturized washing machines. Another type of simple mini washing machine, such as patent CN202322670750.7, is a washing machine with a detachable inner tub. This washing machine does not have the clutch structure of a traditional washing machine, nor does it have an independent impeller. It only washes and spins clothes by rotating the inner tub. Although this type of washing machine has a simple structure and the inner tub is easy to disassemble and assemble, it is difficult to effectively clean clothes when working because it does not have a clutch structure or an independently rotating impeller and a separate inner tub structure. The clothes are not clean and are not clean. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model proposes a novel fully automatic mini washing machine. This washing machine uses a spin-drying tub and a pulsator to form an integrated washing and spin-drying structure, which enables the quick installation or disassembly of the entire spin-drying tub structure. At the same time, the inner tub and the pulsator of this structure can maintain their own independent rotational motion. During washing, the inner tub and the pulsator can form an effective relative motion, achieving a better cleaning effect and making clothes cleaner.

[0005] The specific technical solution of this utility model is as follows: A fully automatic mini washing machine with a detachable drum includes a water tank, a lid, a motor drive, a water inlet device, a drain device, a water level detection device, and a control circuit board. The lid covers the water tank, and the motor drive is located at the bottom of the outer side of the water tank, with its rotating shaft passing through the bottom of the water tank. The motor drive, water inlet device, drain device, and water level detection device are electrically connected to the control circuit board. It also includes a washer-extractor tub, coaxially arranged inside the water tank, comprising a spin-drying tub, a rotating shaft, and a pulsator. The pulsator is located at the bottom of the spin-drying tub. One end of the rotating shaft is fixedly connected to the pulsator, and the other end is connected to the bottom of the spin-drying tub via a bearing. The rotating shaft has a keyway for transmission connection with the rotating shaft of the motor drive.

[0006] In a preferred embodiment, a dehydration bucket lid is also included, which is rotatably mounted on the machine cover for covering the dehydration bucket and can rotate synchronously with the dehydration bucket.

[0007] Furthermore, the machine cover is equipped with a drive motor or a locking structure for controlling the rotation of the dehydration bucket cover.

[0008] As a preferred embodiment, a balance ring is also included, located on the dehydration bucket or the lid of the dehydration bucket.

[0009] In a preferred embodiment, a counterweight is also included, which is evenly distributed around the side wall of the water tank.

[0010] As a preferred embodiment, it also includes a hot air device, which is located on the outside, bottom, or cover of the water tank, with its air outlet facing the inside of the water tank.

[0011] In a preferred embodiment, a sterilization device is also included, which is electrically connected to the control circuit board and is used to sterilize the clothes in the water tank.

[0012] Furthermore, the sterilization device is any one or a combination of an ultraviolet lamp, an electric water heater, an ozone generator, and an electrolyzed water generator.

[0013] In a preferred embodiment, the device also includes a housing, with the water tank located inside the housing.

[0014] Furthermore, it also includes a shock-absorbing device, which is evenly distributed around the water tank. One end of the shock-absorbing device is connected to the water tank, and the other end is connected to the outer casing of the machine body, in order to reduce the vibration of the outer casing of the machine body.

[0015] This utility model of a detachable drum fully automatic mini washing machine connects the spin-dry drum and the pulsator through bearings, forming an integrated washing and spin-drying structure. The entire spin-dry drum can be quickly installed or removed with simple assembly and disassembly, making the structure simpler and easier to install and disassemble. At the same time, through the connection of the bearings, the spin-dry drum and the pulsator can achieve independent rotational movements. During washing, the relatively rotating spin-dry drum and the pulsator can form an effective speed difference, thereby achieving a cleaning effect similar to a clutch, making clothes cleaner.

[0022] like Figure 4 As shown, this embodiment provides a detachable tub fully automatic mini washing machine, including a water tank 1, a lid 2, a motor 3, a water inlet valve 4, a drain pump 5, a water level detection motor 6, and a control circuit board 7. The lid 2 covers the water tank 1, and the motor 3 is located at the bottom outside the water tank 1, with the motor shaft passing through the bottom of the water tank 1. The motor 3, water inlet valve 4, drain pump 5, and water level detection electrode 6 are electrically connected to the control circuit board 7. It also includes a washer-extractor tub 8, which is coaxially arranged inside the water tank 1. The tub includes a spin-dry tub 801, a rotating shaft 802, and a pulsator 803. The pulsator 803 is located at the bottom inside the spin-dry tub 801. One end of the rotating shaft 802 is fixedly connected to the pulsator 803, and the other end is connected to the bottom of the spin-dry tub via a bearing 804. The rotating shaft 802 has a transmission keyway for transmission connection with the rotating shaft of the motor 3. In other words, the motor 3 can directly drive the rotating shaft 802, simultaneously rotating the fixedly connected pulsator 803. Since the dehydration tank 801 is connected to the rotating shaft 802 by the bearing 804, the dehydration tank 801 can still maintain free rotation when the impeller 803 rotates.

[0023] In some embodiments, a dehydration bucket cover 201 is also included. The dehydration bucket cover 201 is rotatably disposed on the machine cover 2, that is, the dehydration bucket cover 201 can rotate freely. Since the dehydration bucket cover 201 is closed on the dehydration bucket 801 when working, the dehydration bucket cover 201 can rotate synchronously with the dehydration bucket 801. At the same time, the dehydration bucket 801 can be limited to make the rotation of the dehydration bucket 801 more stable.

[0024] In some embodiments, the cover 2 is further provided with a drive motor, which is connected to the dehydration drum cover 201 for transmission. The drive motor drives the dehydration drum cover 201 to rotate the dehydration drum 801. Alternatively, a locking structure can be provided on the cover 2. The operation and release of the locking structure control the dehydration drum cover 201 to remain stationary or rotate freely, thereby controlling the dehydration drum 801 to remain stationary or rotate, so that the dehydration drum 801 and the impeller 803 can achieve relative or synchronous movement, thus realizing both washing and dehydration operations. The locking structure can be implemented using electromagnetic push rods, friction brake pads, etc., which are existing technologies in the field. For specific implementation details, please consult existing technical documents; this patent will not provide a specific description of this.

[0025] In some embodiments, a balance ring is provided on the spin-dry tub 801 or the spin-dry tub cover 201. The balance ring reduces eccentric vibrations caused by uneven distribution of clothes during the spin-drying process. Simultaneously, the balance ring increases the weight of the spin-dry tub 801, giving it greater inertia. This allows for a larger speed difference between the pulsator and the spin-dry tub 801 during rotation, thereby improving the washing efficiency of the washing machine. The balance ring is existing technology in the field of fully automatic washing machines; specific implementation methods can be found in existing technical documents. This patent does not provide a detailed description of it.

[0026] In some embodiments, counterweights are evenly distributed around the side wall of the water tank 1. By increasing the weight of the water tank through the counterweights, the vibration amplitude of the water tank 1 during the spin-drying process is reduced, thereby increasing the stability of the washing machine.

[0027] In some embodiments, the washing machine further includes a drying assembly 10, which is located on the outside, bottom or cover 2 of the water tank 1, with its air outlet facing into the water tank 1 to blow hot air into the tank and realize the function of drying clothes.

[0028] The mini washing machine in this embodiment also includes a hot water assembly 9, which is electrically connected to the control circuit board 7 and is used to heat the water in the water tank 1 for better washing or high-temperature sterilization of clothes. In addition to using the hot water assembly 9 for high-temperature sterilization, any one or a combination of ultraviolet lamps, ozone generators, and electrolyzed water generators can be used to sterilize the clothes in the washing machine, making the washing of clothes more hygienic and safe.

[0029] In some specific embodiments, the mini washing machine of this embodiment also includes a casing 11, and a water tank 1 is located inside the casing 11.

[0030] In some embodiments, the washing machine also includes a shock-absorbing device, evenly distributed around the water tank 1. One end of the shock-absorbing device is connected to the water tank 1, and the other end is fixedly connected to the outer casing 11. The shock-absorbing device can further reduce the vibration of the outer casing during the spin-drying process. The shock-absorbing device can be a shock-absorbing rod, a shock-absorbing spring, etc., which are existing technologies in the field of fully automatic washing machines. For specific implementation details, please refer to existing technical documents. This patent will not provide a specific description of these technologies.

[0031] The process of washing and spin-drying clothes using the mini washing machine in this embodiment is as follows: First, open the cover 2, put in the washer-spinner tub 8, put the transmission keyway of the rotating shaft 802 onto the rotating shaft of the motor 3, tighten the fixing screws, and then close the cover 2. Alternatively, the fixing screws can be omitted because the spin-dry tub cover 201 on the cover 2 will be randomly placed on the spin-dry tub 801 to limit and fix the spin-dry tub 801. Then, the washing machine is turned on. According to the preset washing program, the water inlet valve 4 is opened to fill the water tank 1 with water. When the water level reaches a certain height, the water level detection electrode 6 transmits a signal to the control circuit board 7, and the water filling stops. Then, the motor 3 drives the rotating shaft 802 to rotate the pulsator 803, agitating the water in the tub and washing the clothes. During the washing process, the pulsator 803 rotates in both directions in short intervals. Because there is a bearing 804 between the spin-dry tub 801 and the pulsator 803, and the spin-dry tub 801 remains stationary due to inertia, a relative speed difference can be formed between the pulsator 803 and the spin-dry tub 801, thus achieving a high cleaning power similar to a clutch structure. After washing for a certain period of time, the drain pump 5 is turned on to drain the water in the water tank 1, and then spin-drying begins. The motor 3 starts slowly, driving the pulsator 803 to rotate. The pulsator 803 moves the clothes in the tub, and the clothes in turn drive the spin-dry tub 801 to start rotating synchronously, and then the speed is gradually increased to achieve high-speed spin-drying. After washing, if you need to clean the inside of the washing machine, simply open the lid and you can easily remove the washer-extractor tub for cleaning without even using any tools. It's very simple, convenient, and quick.

[0032] The technical means disclosed in this utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
