The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides an intelligent sterilization control system and method for a washing machine, which are described below respectively.

[0023] Figure 1 A schematic diagram of an embodiment of the intelligent sterilization control system for a washing machine provided by the present invention and Figure 2 The system schematic diagram of an embodiment of the intelligent sterilization control system of the washing machine provided by the present invention includes: An MCU (Microcontroller Unit) control module is communicatively connected with the mobile terminal, and is used to receive a control instruction from the mobile terminal to turn on the intelligent disinfection of the washing machine within a preset time and obtain a washing end status signal of the washing machine, and generate a sterilization drive signal based on the control instruction to turn on the intelligent disinfection of the washing machine within the preset time and the washing end status signal of the washing machine; A first constant current drive control module 102, electrically connected to the MCU control module 101, for generating a sterilization control instruction based on the sterilization drive signal; The UVC (Ultraviolet C disinfection) sterilization module is electrically connected to the first constant current drive control module 102 and is used to control its own power on and off based on the sterilization control instruction.

[0024] It is understandable that the intelligent sterilization control system of a washing machine provided in the present application includes a housing and a circuit board, on which are integrated: an MCU controller, a WIFI (Wireless Fidelity) module, a constant current drive control module, a UVC sterilization module 103, an atmosphere light module, and an illumination light module. The housing is designed with a receiving cavity, and the circuit board is placed in the receiving cavity.

[0025] It can be further understood that the sterilization module of the present invention can not only work when the washing machine is working, but also start the sterilization function at a fixed time when the washing machine stops running after washing clothes, so as to prevent a large number of bacteria from growing in the washing machine and maintain a sterile environment in the washing machine for a long time. The interval of the scheduled sterilization can be set through the APP (Application), such as starting once every 2 hours; and it can also send a text message to the user through the cloud in real time through the built-in WIFI module, indicating that the clothes have been washed and please take out the clothes in time. Combining these functions makes the washing machine more intelligent. The built-in light sensing module of the present invention can sense the intensity of the surrounding light, and control the adaptive adjustment of the lighting module according to the intensity of the surrounding light, which is convenient for the user to turn on the light when opening the cover when the light is dim, and can automatically turn off when the light is sufficient, thereby saving energy and being more environmentally friendly. The present invention adds an atmosphere light, which adds the functions of intermittent flashing and long lighting, reminding the user to take out the washed clothes in time, making the product more humane.

[0026] It can be further understood that the system also includes: a light sensor for collecting ambient light to achieve adaptive brightness adjustment, that is, when the brightness detected by the light sensor reaches or exceeds the set brightness value, the lighting function is automatically turned off, otherwise it is adaptively adjusted according to the ambient light, so that the ambient light always remains at the set brightness value.

[0027] It can be further understood that the UVC sterilization module 103 integrates several UVC ultraviolet lamp beads on a PCB (Printed Circuit Board). The AIGaN-based deep purple LED (250 nm<λ<285 nm) destroys and terminates the DNA (Deoxyribonucleic Acid) replication process of bacteria, spores and viruses through ultraviolet irradiation, thereby achieving the purpose of effective sterilization and inhibition of bacterial reproduction.

[0028] It can be further understood that when the washing machine is working normally, the detection signal is transmitted to the MCU control module 101, and the MCU control module 101 outputs a corresponding signal to control the opening of the UVC sterilization module 103. In any case, as long as the lid is opened, the UVC module is always in a closed state to prevent ultraviolet rays from causing harm to the human body.

[0029] When the washing machine is not used for a long time and the lid is closed, or the clothes are not taken out in time after the washing work of the washing machine is finished, the inner wall of the washing machine will slowly breed bacteria over time, affecting the safety during use. At this time, a fixed cycle time can be set through the MCU controller to perform a sterilization. For example, it can be designed that after 2 hours from the last use, the washing machine does not work during this period, and the MCU controller outputs the first PWM (Pulse Width Modulation) signal to the first constant current drive control module, thereby starting a sterilization, so as to realize the function of regularly starting the sterilization and keep the inner wall of the laundry compartment clean and hygienic for a long time; When the washing machine lighting is turned on, the light sensor also works at the same time, that is, when the lighting is on, the light sensor is always in the detection state to collect the ambient light. When the ambient light is greater than or equal to the set brightness value, the MCU outputs the second PWM signal to the second constant current drive control module. At this time, the second PWM signal is 1-100% automatically adjusted, and the second constant current drive control module changes the driving current according to the change of the second PWM signal, thereby realizing the adaptive adjustment of the brightness of the lamp beads and keeping the light at the set brightness value. This situation mainly solves the problem that under good lighting conditions, there is no need to turn on the lighting, avoiding waste of resources and making the product more energy-saving and environmentally friendly. When the washing program of the washing machine ends, if the clothes are not taken out in time within the cycle set by the user, the atmosphere light can be set through the APP program to stay on or flash, so as to serve as an indicator light to remind the user to take out the clothes in time. At this time, the APP can also send a message to the user to remind the user to take out the clothes in time after the washing machine ends, making the product more user-friendly. For the above additional functions, users can set certain functions to be turned on or off through the APP according to their own usage habits.

The second constant current drive control module is electrically connected to the MCU control module 101, and is used to generate a drive signal according to the control instruction of the MCU control module 101. The drive signal is a PWM signal, and the current size of the constant current drive is adjusted based on the PWM signal to achieve adaptive adjustment of the lighting.

[0032] It can be further understood that when the washing machine is working normally, the detection signal is transmitted to the MCU control module 101, and the MCU control module 101 outputs a corresponding signal to control the opening of the UVC sterilization module 103. In any case, as long as the lid is opened, the UVC module is always in a closed state to prevent ultraviolet rays from causing harm to the human body.

[0033] When the washing machine is not used for a long time and the lid is closed, or the clothes are not taken out in time after the washing work of the washing machine is finished, the inner wall of the washing machine will slowly breed bacteria over time, affecting the safety during use.

At this time, the second PWM signal is 1-100% automatically adjusted, and the second constant current drive control module changes the driving current according to the change of the second PWM signal, thereby realizing the adaptive adjustment of the brightness of the lamp beads and keeping the light at the set brightness value. This situation mainly solves the problem that under good lighting conditions, there is no need to turn on the lighting, avoiding waste of resources and making the product more energy-saving and environmentally friendly. When the washing program of the washing machine ends, if the clothes are not taken out in time within the cycle set by the user, the atmosphere light can be set through the APP program to stay on or flash, so as to serve as an indicator light to remind the user to take out the clothes in time. At this time, the APP can also send a message to the user to remind the user to take out the clothes in time after the washing machine ends, making the product more user-friendly.

[0037] It can be understood that the third constant current drive control module needs to adopt a constant current drive to drive the LED chip based on the volt-ampere characteristics of the LED, and generates a drive signal according to the control instruction of the MCU control module 101. The drive signal is a PWM signal. The switch of the constant current drive is adjusted based on the PWM signal, thereby realizing the long-lasting or flashing reminder of the atmosphere light.
