Description

Technical Field

[0001] The utility model relates to the field of washing machines, in particular to a shared washing machine with a self-cleaning function. Background Art

[0002] Shared washing machines are a new sharing economy model that allows users to use washing machines for laundry in public places such as commercial areas and campuses. This service not only improves laundry efficiency and saves space, but also reduces users' purchase and maintenance costs, reflecting the environmental protection and high efficiency concept of the sharing economy. The use process of shared washing machines is simple. Users make reservations for nearby washing machines through mobile phone applications. After arriving, they scan the code to unlock and pay, and start the washing machine after selecting the washing mode. After completion, the user retrieves the clothes. In addition, shared washing machines are usually equipped with smart payment systems and smart monitoring systems to ensure convenience and safety of use. From an environmental protection perspective, shared washing machines reduce the production and disposal of new washing machines through efficient utilization, reduce carbon emissions, and reduce the use of detergents, which is beneficial to environmental protection.

[0003] At present, the existing shared washing machines are usually ordinary washing machines, and the drum of the existing washing machines usually does not have a self-cleaning structure. When self-cleaning is required, clean water and detergent are injected into the drum, and the rolling operation drives the water flow to clean the inner wall of the drum to achieve self-cleaning. However, this cleaning method cannot effectively remove stubborn dirt on the inner wall of the drum, thereby reducing the effect of self-cleaning. Therefore, there is an urgent need for a shared washing machine with a self-cleaning function. Utility Model Content

By providing the water-permeable holes at the bottom of the connecting frame 6, when the drum 4 of the shared washing machine needs to be drained, the drain valve 5 is opened, and the water flows through the water-permeable holes through the connecting frame 6 into the drain valve. The micro high-pressure water pump 7 is installed in the cavity, and its input end is located directly above the drain valve 5. When the drum 4 needs to be self-cleaned, the micro high-pressure water pump 7 can extract water from the drum and output it. The output end of the micro rotary high-pressure nozzle 9 is located on its top conical surface, and the output end is composed of a plurality of groups of spray holes. The input end of the micro rotary high-pressure nozzle 9 is connected to the output end of the micro high-pressure water pump 7 through the water conduit 8, and the water output by the micro high-pressure water pump 7 enters the micro rotary high-pressure nozzle through the water conduit 8. 9, and the output end of the micro-rotating high-pressure nozzle 9 sprays toward the inner wall of the drum 4 to clean the inner wall of the drum 4. A connecting ring 401 is fixedly installed at the middle end of the bottom surface of the drum 4. The inner wall of the connecting ring 401 is rotatably connected with a drain pipe 402. The other end of the drain pipe 402 penetrates the washing machine housing 1 and extends from the middle end of the bottom end of the back thereof. The connecting ring 401 is installed at the middle end of the bottom surface of the drum 4. The connecting ring 401 is rotatably connected to the drain pipe 402. When the drum 4 is rotating to wash clothes, the drain pipe 402 is prevented from interfering with the drum 4 and preventing it from rotating normally. At the same time, the sewage in the drum 4 can be discharged through the drain pipe 402. The washing machine control panel 3 is used to control the shared washing machine to start washing clothes and control the micro- The rotating high-pressure nozzle 9, the micro high-pressure water pump 7, the drain valve 5 and the ultrasonic generator 10 are started and stopped. The washing machine control panel 3 is fixedly installed on one side of the top front face of the washing machine housing 1 and is electrically connected to the micro rotating high-pressure nozzle 9, the micro high-pressure water pump 7, the drain valve 5 and the ultrasonic generator 10 respectively. When the drum 4 needs to be cleaned, the cleaning liquid mixed with water is sent into the drum 4, and the washing machine control panel 3 controls the ultrasonic generator 10 to start, and the ultrasonic generator 10 works, and ultrasonic waves are emitted through the ultrasonic generator 10. The ultrasonic high-frequency vibration generates tiny bubbles and bursts in the mixed liquid of the cleaning liquid and water, generating a local high-temperature and high-pressure environment, thereby impacting the dirt on the inner wall of the drum 4, causing it to loosen and fall off. Subsequently,The control panel 3 of the washing machine is controlled to close the ultrasonic generator 10 and discharge half of the mixed liquid of the cleaning liquid and water in the drum 4.

At the same time, the micro rotating high-pressure nozzle 9 can rotate, and then the inner wall of the drum 4 can be washed without dead angles. When the dirt in the drum 4 is washed, the control panel 3 of the washing machine controls the drain valve 5 to open and discharge the remaining mixed liquid of the cleaning liquid and water from the drum 4. It should be noted that in order to prevent dirt from clogging the drain valve 5, the micro high-pressure water pump 7 and the micro rotating high-pressure nozzle 9, a filter can be installed at the water permeable hole at the bottom of the connecting frame 6 to block dirt and impurities.

[0023] Ultrasonic waves are emitted by the ultrasonic generator 10, and the high-frequency vibration of the ultrasonic waves generates tiny bubbles that burst in the mixed liquid of the cleaning liquid and water, thereby generating a local high-temperature and high-pressure environment, thereby impacting the dirt on the inner wall of the drum 4, causing it to loosen and fall off. Subsequently, the micro-high-pressure water pump 7 and the micro-rotating high-pressure nozzle 9 are started, and the micro-high-pressure water pump 7 extracts the remaining mixed liquid of the cleaning liquid and water in the drum 4, and sends it to the micro-rotating high-pressure nozzle 9, which is sprayed toward the inner wall of the drum 4 while rotating, to flush the remaining dirt, thereby achieving a dead-angle flushing of the stubborn dirt on the inner wall of the drum 4, effectively removing the dirt on the inner wall of the drum 4, and improving the self-cleaning effect.

When the clothes are washed, users who need to wash clothes later can pour water and cleaning liquid into the drum 4, and control the shared washing machine to start through the washing machine control panel 3. The ultrasonic generator 10 works, and ultrasonic waves are emitted through the ultrasonic generator 10. The high-frequency vibration of the ultrasonic wave generates tiny bubbles and bursts in the mixed liquid of the cleaning liquid and water, generating a local high temperature and high pressure environment. , and then impact the dirt on the inner wall of the drum 4 to loosen it and fall off. Subsequently, the washing machine control panel 3 is controlled to turn off the ultrasonic generator 10 and discharge half of the mixed liquid of cleaning liquid and water in the drum 4. The washing machine control panel 3 is controlled to start the micro high-pressure water pump 7 and the micro rotating high-pressure nozzle 9.
