Abstract

A washing machine having a sterilization function is provided to sterilize the laundry using a LED by evenly irradiating the ultraviolet ray to the laundry. A washing machine having a sterilization function removes the bacteria having in the washing machine using an ultraviolet-ray LED(6). The wavelength of the ultraviolet-ray LED is the range of 200~550nm. The washing machine having the sterilization function comprises a power supply unit(4) and a controller(7). The power supply unit and the controller operate the ultraviolet-ray LED. The DC(direct current) or the AC(alternating current) power source is supplied. The DC is operated with continuous wave or the pulse wave. The operation time is controlled with a timer.

Description

Sterilization washing machine using LED {LED USED STERILIZING WASHER}

Conventional washing machines use water and detergents or silver, or special detergents to sterilize, but the effect is not very high. To protect laundry from germs, UV LEDs with ultraviolet wavelengths that can be sterilized are installed inside the washing machine to sterilize germs in the laundry of the washing machine so that they can be washed without contamination. Power is supplied to the UV LEDs at the start of washing. To sterilize.

In general washing machines, sterilization is done using silver nanotechnology or laundry detergent, but it is not very effective.

Ultraviolet rays sterilize by using ultraviolet lamps in medical sterilizers or general sterilizers. These lamps are inconvenient to install, and there are various inconveniences such as supplying power or replacing them in case of failure. The new method is to use UV LEDs to make products that are simple, easy to mount and have a long service life.

 Therefore, an object of the present invention is to install a UV LED with a sterilizing ultraviolet light wavelength in the washing machine so that the ultraviolet light is emitted from the inside of the washing machine toward the laundry so that the laundry is irradiated with UV light evenly. The problem is that the wiring for processing and powering can be operated without problems even when the tank is rotating.

 The method of mounting the UV LED in the tank that wraps and runs the laundry is to make the tank into a double round or one-piece round cylinder, and to install the LED in the inner cylinder and, of course, to have a waterproof function so that water does not enter and prevent leakage of water due to leakage. In addition, the UV LED is installed in the spinning tank and must move with the tank so that the power supply wiring is connected from the bottom of the tank so that it does not become a problem when rotating.

 Another method is to use a wireless power unit to wirelessly supply UV LEDs to remove laundry parasitic germs to wash safe laundry free of contamination.

 The present invention as described above is a washing machine that is excellent sterilization effect of washing the clothes of the washing machine safely without being contaminated by sterilizing bacteria in the laundry using ultraviolet LED.

 Double the tank that wraps around the laundry, and the LEDs are placed in the upper and lower parts in accordance with the height of the tank, and the batch is disposed over 360 degrees to emit ultraviolet rays throughout the laundry. The water tank is formed in a single shape and wrapped in transparent glass or plastic on the front part of the LED to make it waterproof, or the water tank is made of double circular or one-piece round cylinders, and the LED is mounted inside the tank to prevent water from entering by leaking water. Because of this, the short circuit does not occur and the UV LED is installed in the rotating tank to move with the tank, so the wiring for supplying power is connected to the bottom of the tank so that it does not become a problem when rotating.

 In addition, it has a power supply device that supplies power to the LED and a control device that controls it, and operates the LED according to the functions of time control, washing, rinsing, and dehydration so that ultraviolet light is transmitted to the laundry to be sterilized as much as possible. Naturally, transparent glass or plastic material through which ultraviolet rays are transmitted can be used to transmit ultraviolet light well, and special materials such as ultraviolet light only can be used.

 Ultraviolet wavelength uses LED from 250nm to 550nm, and especially 280nm or 265nm wavelength is very effective for sterilization, it is characterized by using 280nm wavelength or 265nm wavelength.

 Another way is to use a wireless power device to wirelessly power UV LEDs to remove bacteria that are parasitic on laundry to create a safe laundry free of contamination.

 A representative diagram is a schematic diagram in which the present invention is installed, and a motor part in which a washing machine operates is naturally required, but is omitted here. When AC 220V power is supplied, the power supplied to the switch (1) through the fuse is supplied to the washing machine only when the switch is operated. When the washing machine is supplied with power (7), the washing machine control device, the LED control device and the timer are operated. When various operations are performed in the control unit, (2) power is supplied to the power supply unit, and (3) ultraviolet rays are emitted from the LEDs.

 1 is a diagram in which an ultraviolet LED 6 is installed, and there are DC power supply devices 2 and 4 for supplying power to the ultraviolet LED 6, and a timer is set inside and outside the power supply to set a time. The switch or the sense (5) can be operated when the door of the washing machine is closed, or by supplying power to the ultraviolet LED (6) to operate in a variety of ways depending on the operation of the washing machine to emit ultraviolet light.

Figure 2 briefly shows that the LED is disposed in the tank.
