[0006] As a further description of the above technical solution:

[0007] A sealing ring is arranged in the cavity, a groove is arranged on the outer surface of the downlight shell, and the sealing ring is clamped in the groove.

[0008] As a further description of the above technical solution:

[0009] The cavity is provided with potting glue inside, and the PCB lamp board, the PCB power board and the wiring harness assembly are all fixed on the potting glue.

[0010] As a further description of the above technical solution:

[0011] The material of the potting glue is polyurethane.

[0012] As a further description of the above technical solution:

[0013] The sealing ring is made of nitrile rubber.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] In the utility model, the technology of combining three kinds of lamps, namely white light, blue light and deep ultraviolet sterilization lamp, into a barrel lamp is adopted. When the washing machine is working, the blue light lamp and the deep ultraviolet sterilization lamp work to sterilize the clothes, and at the same time, there is the effect of atmosphere light. When the door of the washing machine is opened, the white light lamp works to facilitate the user to take the clothes. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 The utility model provides a technical solution: a three-in-one washing machine tub lamp, comprising a glass cover 1, a downlight housing 2, a PCB lamp board 3, a PCB power board 4 and a plurality of LED lamp beads 5, wherein the glass cover 1 is clamped on the downlight housing 2, a cavity 6 is provided inside the downlight housing 2, the PCB lamp board 3, the PCB power board 4 and the plurality of LED lamp beads 5 are all located in the cavity 6, the plurality of LED lamp beads 5 are fixed on the end surface of the PCB lamp board 3, and the PCB lamp board 3, the PCB power board 4 and the plurality of LED lamp beads 5 are electrically connected through a harness assembly 7;

[0023] A sealing ring 8 is provided in the cavity 6, and a groove 9 is provided on the outer surface of the downlight housing 2. The sealing ring 8 is clamped in the groove 9. The use of the sealing ring 8 can adapt to the pressure and temperature in different working environments, and has good sealing performance within a specified range, thereby improving the sealing effect of the washing machine barrel lamp;

[0024] The cavity 6 is provided with a potting glue 10 inside, and the PCB light board 3, the PCB power board 4 and the wiring harness assembly 7 are all fixed on the potting glue 10;

[0025] The material of the potting glue 10 is polyurethane.

[0026] The sealing ring 8 is made of nitrile rubber.

[0027] Working principle: First, when the three-in-one washing machine barrel light is in use, the washing machine main control board outputs a DC12V voltage, and the current is controlled at about 50mA. The LED lamp beads 5 on the PCB lamp board 3 are controlled through the wiring harness assembly 7 to provide voltage for the LED lamp beads 5 with different functions, one for the white light lamp and one for the deep ultraviolet sterilization lamp and the blue light lamp. The main control board controls the output of the voltage. When the washing machine is working, after the washing machine door is closed, the main control board supplies power to the deep ultraviolet sterilization lamp and the blue light lamp to turn on the blue light and the sterilization lamp. When the washing machine door is opened, the white light works to play a lighting role. The three-in-one barrel light has the three functions of lighting, sterilization, and atmosphere at the same time.
