[0064] In this embodiment, the first air inlet valve controls the opening and closing of the first air inlet branch 4, thereby controlling the opening and closing of the first air inlet branch 4 and the air chamber 32; the second air inlet valve 51 controls the opening and closing of the second air inlet branch 5, thereby controlling the opening and closing of the air chamber 32 and the outside atmosphere, so as to sterilize and deodorize the clothes processing drum 2 and the laundry according to the usage of the clothes processing equipment or the actual usage needs of the user.

[0065] Example 4

[0066] like Figures 1 to 3 As shown, this embodiment is a further limitation of the above embodiments one to three. The air chamber 32 is provided with a photoplasma tube 34 and a fan 33. The photoplasma tube 34 is used to irradiate the air in the air chamber 32, and the fan 33 is used to draw air from the first air inlet branch 4 or the second air inlet branch 5 into the air chamber 32.

[0067] In this embodiment, the fan 33 draws the airflow from the air inlet 35 into the air chamber 32 through the air outlet 6 and flows towards the air outlet 36. During the gas flow, the photo-plasma tube 34 irradiates the gas to form a bactericidal gas containing oxides, so as to sterilize the clothing processing equipment.

[0068] In this embodiment, the ion clusters generated by the light tube turn particles in the air into oxidants. When they encounter harmful substances, the overall photoion clusters are very active. Under the same polluted environment, they destroy organic matter 180 times faster than ultraviolet light and 2000 times faster than ozone. They remove biological pollutants from the air—killing and destroying bacteria, viruses, and mold in the air and on object surfaces, reducing the spread of germs in the air.

[0069] like Figures 1 to 3 As shown, in this embodiment, the photoplasma generating module 3 includes a housing 31, which surrounds an exhaust chamber 32. The housing 31 has an air inlet 35 and an air outlet 36 for the exhaust chamber 32.

[0073] In this embodiment, the photoplasma tube 34 can emit photoplasma and ion clusters. The emitted photoplasma and ion clusters cause oxygen and water molecules in the gas chamber 32 to decompose into hydroxide ions, free oxygen atoms, superoxide ions and other oxidants. It also decomposes odor substances carried in the circulating airflow into inert compounds such as carbon dioxide and water. The air irradiated by the photoplasma tube 34 forms a bactericidal gas that is introduced into the clothing treatment drum 2. This not only sterilizes the inside of the clothing treatment drum 2, but also sterilizes the clothes inside. It has a particularly good sterilization effect on clothes that cannot withstand high temperatures. At the same time, the odor of the clothes is quickly and easily removed.

Among these, the UVC band has a wavelength of 200–275 nm, with the 253.7 nm UVC band exhibiting highly effective sterilization. The UVD band has a wavelength of 100–200 nm, with the 185 nm UVD band capable of exciting oxygen and water in the air to produce photoplasma.

[0079] In this embodiment, a light plasma concentration detection device is arranged in the air chamber 32 or the clothes treatment cylinder 2, which is used to detect whether the light plasma concentration in the air chamber 32 or the inside of the clothes treatment cylinder 2 meets the sterilization requirement.

[0080] In this embodiment, an odor detection device is arranged in the clothes treatment cylinder 2, which is used to detect the odor concentration and the taste concentration of the clothes treatment cylinder 2 or the clothes inside the clothes treatment cylinder 2, so as to accurately control the operation of the light plasma generating module 3.
