Background

With the development of technology at any time, the invention and the use of the washing machine not only represent the intelligent achievement of modern industrial revolution, but also release thousands of people from heavy household labor, and become indispensable living necessities of people. However, the current washing machine achieves sterilization mainly by the following methods: sterilizing the cleaning barrel by ultraviolet irradiation; adding a disinfection laundry detergent for disinfection; sterilizing at high temperature; and (5) ozone sterilization. The following problems mainly exist in the prior art:

1. ultraviolet sterilization cannot achieve 360-degree irradiation sterilization. Ultraviolet radiation generally irradiates only the outer layer surface of the clothes, and the clothes laminated together inside cannot be sterilized by radiation.

2. The disinfection of the disinfection laundry detergent is not easy to control the adding amount, the disinfection effect cannot be achieved when the amount is too small, the clothes can be damaged when the amount is too large, and the disinfection laundry detergent possibly remains after use, so that potential danger exists for human bodies, particularly for small babies.

3. High temperature sterilization is not suitable for clothes which are not heat-resistant, such as clothes made of sweater, wool and silk.

4. Ozone sterilization drawbacks: the ozone generation amount and the dissipation time have strong uncertainty factors, when people open the washing machine to remove clothes, ozone may not be completely converted into oxygen, and overflowed ozone can cause harm to human bodies. Ozone must be within safe standards below which there is no disinfection and above which it is harmful to humans, and is a toxic gas for humans, which has many different chemical and toxicological properties than oxygen, with pungent odors and extremely oxidizing properties.

Example 1

The present embodiment provides a drum washing machine including:

the device comprises a shell 10, wherein an inner cylinder 101 and an outer cylinder 100 are arranged in the shell 10;

an ultraviolet generator 105, wherein the ultraviolet generator 105 is arranged on the inner wall of the inner barrel 101;

an ozone detection sensor 102, the ozone detection sensor 102 being disposed inside the casing 10 and connected to the tub 100 through a gas passage 103;

a control unit electrically connected with the ultraviolet generator 105 and the ozone detecting sensor 102;

the control unit activates the ultraviolet ray generator 105 and the ozone detecting sensor 102, and controls the ultraviolet ray generator 105 to stop operating or reduce the emission power when the ozone concentration value is higher than a preset value.

Preferably, a filter screen 104 is provided between ozone detecting sensor 102 and outer tub 100.

The antibacterial crystal is arranged in the lifting rib of the inner cylinder 101. Preferably, the antibacterial crystal is a nano silver ion crystal.

The lifting rib is one of the main components of the inner drum 101 of the drum washing machine, and has the main functions that when the drum washing machine washes clothes, on one hand, the clothes generate friction force with the lifting rib, and the clothes close to the lifting rib and the relative motion part rub against each other to generate rubbing action; on the other hand, the lifting ribs drive the clothes to rotate together, the clothes are lifted out of the liquid level and are conveyed to a certain height, and the clothes fall into the laundry detergent again under the action of gravity, and impact with the laundry detergent to generate stick beating and falling effects, so that the washing effect is achieved.

The silver ions have the sterilization effect, and a proper amount of nano silver ion crystals are added into the structures such as the wall of the inner cylinder 101, and when the washing machine works, the silver ions are released for sterilization.

The nano silver ion antibacterial crystal is added into the lifting ribs of the inner barrel 101 of the washing machine, has strong inhibiting and killing effects on dozens of pathogenic microorganisms such as escherichia coli, gonococcus, chlamydia trachomatis and the like, and cannot generate drug resistance. These crystals are hidden in the promotion muscle of washing machine inner tube 101, meet water and release silver ion and carry out the degerming to the clothing, and this kind of degerming mode is not limited to the temperature, can all trigger the degerming efficiency under various laundry modes, is applicable to the clothing of various materials, and the practicality is very strong. Silver ion disinfection is not like disinfection laundry detergent disinfection, and washing number of times is less, the water of using sparingly.

In order to achieve better comprehensive sterilization effect, it is preferable that at least 3 groups of ultraviolet ray generators 105 are installed on the wall of the drum inner 101 of the washing machine, and after washing, the clothes are sterilized by ultraviolet irradiation. Different ultraviolet irradiation intensities are set according to different clothes materials, such as woolen sweaters, jeans, sweaters and the like. After the irradiation is realized for a period of time through a program, the rotary drum rotates, vibrates and the clothes roll and shift, so that the full ultraviolet irradiation is realized, the irradiation of 360 degrees is realized, and the sterilization effect is improved.

An ozone detecting sensor 102 installed inside the washing machine casing 10 and connected to the tub 100 through a gas passage 103. After the ozone in the inner drum 101 is detected by the ozone detection sensor 102, the ozone concentration reaches the standard, the washing machine can be opened to take out the clothes.

The ozone detection sensor 102 is mainly composed of a low-pressure ultraviolet lamp, a light wave filter, an incident ultraviolet reflector, an ozone absorption cell, a sample photoelectric sensor, a sampling photoelectric sensor, an output display and a circuit component.

The ozone detection sensor 102 uses the principle of ultraviolet absorption, uses a stable ultraviolet lamp light source to generate ultraviolet light, and uses a light wave filter to filter out ultraviolet light with other wavelengths, and only allows the ultraviolet light with the wavelength of 253.7nm to pass through. The sample passes through the sample photoelectric sensor and then the ozone absorption cell and reaches the sampling photoelectric sensor. The ozone concentration can be obtained by comparing the electric signals of the sample photoelectric sensor and the sampling photoelectric sensor and calculating through a mathematical model.

The basic circuit of the device consists of six parts, namely a power supply part, an ultraviolet lamp control part, an ultraviolet ray sample detection part, an ultraviolet ray sampling detection part, a logarithmic amplifier Log100 and an analog output part and a display part.

The power supply part mainly generates a high-voltage power supply required by the ultraviolet lamp and simultaneously generates +15V direct current required by the circuit board. The ultraviolet lamp control part mainly controls the current of the ultraviolet lamp within a constant allowable range, the lamp current can be automatically adjusted when the lamp current is too high or too low, and if the lamp current is not adjusted, the service life of the ultraviolet lamp is up, a red lamp on the panel is lightened, and a user is prompted to replace the new ultraviolet lamp. The standard ultraviolet detection and sampling ultraviolet detection part is also a more critical part, and the photoelectric sensor converts an optical signal of ultraviolet into a voltage signal, then the voltage signal is processed and amplified by the operational amplifier twice, and the signal is sent to the Log100 for calculation and then displayed and output. The analog output 0-20mA is in linear relation with the ozone concentration.

Preferably, the optical filter allows only 253.7nm wavelength ultraviolet light to pass through.
