Abstract
Description
Technical Field
[0001] This invention belongs to the field of washing machine cleaning, specifically relating to a fully automatic cleaning system device and control method for drum washing machines. Background Technology
[0002] In daily use, there are only two ways to clean the inside and outside of the washing machine drum. One is mechanical, which involves disassembling the inner and outer drums for cleaning. Reassembling and reassembling after cleaning has disadvantages: the disassembly process can cause some damage to the washing machine, and repeated disassembly may lead to greater vibrations. The second method is chemical cleaning solutions, usually containing chlorine and acid. The cleaning agent is poured into the washing machine and used in conjunction with its self-cleaning function. This cleaning mode typically lasts for more than an hour, uses a lot of water, is inconvenient for frequent cleaning, and may leave cleaning solution residue inside the washing machine, potentially causing secondary contamination of clothes. Summary of the Invention
[0003] This invention addresses the shortcomings of existing washing machine cleaning technologies by adding a cleaning system device inside the washing machine, thereby achieving cleaning of the washing machine, improving washing performance, and shortening washing time. Attached Figure Description
[0004] Figure 1 This is a schematic diagram of the washing machine cleaning system device and the location of the control device according to the present invention.
[0005] Figure 2 This refers to the location of the cleaning device in the washing machine cleaning system described in this invention.
[0006] In the diagram: 1. Main control turntable; 2. Disinfectant dispensing port; 3. Steam generator; 4. Ultraviolet lamp disinfection device; 5. Ultrasonic cleaning device; 6. Disinfectant, high-pressure water and steam cleaning device; 7. Inner tank; 8. Outer tank. Detailed Implementation
[0007] Figure 1 When the washing machine receives a function selection command from the control panel, the control device selects one or more cleaning devices to start.
[0008] Figure 2 When the high-temperature steam cleaning function is activated, the steam generator 3 inside the washing machine will quickly generate high-temperature steam. The steam is input into the main control turntable 1 through the pipe, and then enters the high-temperature steam cleaning device 6. The device starts to rotate, and performs all-round, thorough disinfection of the inside of the washing machine.
[0009] When the washing machine is in sleep mode, the ultraviolet lamp disinfection function can be activated. The device rotates slowly, and the ultraviolet lamps evenly distributed on a certain group of ultraviolet lamp disinfection devices 4 begin to irradiate, achieving deep disinfection.
[0010] When the disinfectant spray cleaning is started, the disinfectant is put into the separate disinfectant port 2, which is then transmitted to the turntable 1 through the pipe, and then sprayed or sprayed intermittently through the device. Combined with high-pressure water, it performs deep cleaning of the washing machine, effectively removing stubborn stains and bacteria.
[0011] When ultrasonic cleaning is started, the ultrasonic transmitter installed on a set of ultrasonic cleaning devices 5 is activated. This set of devices rotates to the bottom of the washing machine drum, and the water level is above this set of devices. It has three frequency modes: high and low frequency, and high, low, medium, and high frequency, which users can flexibly select according to their actual situation. This function is also applicable to both washing clothes and self-cleaning the washing machine. Activating this function while washing clothes can not only effectively reduce washing time, but also significantly increase the cleanliness of the clothes. When the washing machine is self-cleaning, it can also achieve ideal cleaning results, keeping the washing machine in good working condition at all times.
[0012] The high-pressure water cleaning function involves water being piped into a set of high-pressure water cleaning devices 6. As the devices and the washing machine drum rotate, the washing machine is sprayed with high-pressure water for cleaning.
Claims
1. A fully automatic cleaning system device and control method for a drum washing machine. The system is located in the gap between the inner and outer drums of the washing machine. The system includes high-pressure water cleaning, ultrasonic cleaning, disinfectant spray cleaning, high-temperature steam cleaning, and ultraviolet disinfection. It can be manually activated via the washing machine's integrated panel or automatically activated after the washing cycle is completed. It is used to thoroughly clean all gaps between the inner and outer drums of the washing machine, effectively improving the cleanliness of the washing machine, preventing cross-infection, saving water, and saving time. The system consists of a cleaning device and a control device. The cleaning device is located in the gap between the inner and outer drums and includes a high-pressure water cleaning device, an ultrasonic cleaning device, a disinfectant spray cleaning device and a disinfectant dispensing port, a high-temperature steam cleaning device and a steam generator, and a high-temperature ultraviolet disinfection device. The control device, i.e., the main control turntable, is located at the central axis between the inner and outer drums. After the user selects a cleaning function, they issue a command through the integrated panel. The control device activates one or more sets of cleaning devices according to the function. When the high-temperature steam cleaning function is activated, the steam generator inside the washing machine quickly generates high-temperature steam. The steam is input to the main control turntable through a pipe and then enters the high-temperature steam cleaning device, which begins to rotate. The washing machine undergoes comprehensive, thorough disinfection inside. When the washing machine is in sleep mode, the UV disinfection function can be activated. The device rotates slowly, and UV lamps evenly distributed on a set of devices begin irradiation for deep disinfection. When the disinfectant spray cleaning function is activated, disinfectant is added to a separate disinfectant inlet, piped to a rotating disc, and then sprayed or intermittently through a device. Combined with high-pressure water, this deeply cleans the washing machine, effectively removing stubborn stains and bacteria. When the ultrasonic cleaning function is activated, the ultrasonic transmitter on a set of devices is activated. This set of devices rotates to the bottom of the washing machine drum, with the water level above the device. It offers three frequency modes: high / low frequency and high / low / medium / low frequency, allowing users to choose flexibly according to their needs. This function is applicable to both washing clothes and self-cleaning. Activating this function while washing clothes not only effectively reduces washing time but also significantly increases the cleanliness of clothes. It also achieves ideal cleaning results during self-cleaning, keeping the washing machine in good working condition at all times. When the high-pressure water cleaning function is activated, water is piped to a set of cleaning devices, and as the devices and the washing machine drum rotate, high-pressure water is sprayed onto the washing machine for cleaning.
