The specific embodiment:
Embodiment 1:
Present embodiment provides and is independent of electric refrigerator housing body deodorizing sterilizing device in addition, is mainly used in the cold room of electric refrigerator, directly is placed in the cold compartment of refrigerator and uses.
Referring to Fig. 1, air channel 1 is set, and in air channel 1, circulating fan 2 is set, be in air channel inlet 3 on the diverse location and ducting outlet 4 respectively with refrigerator between the chamber be communicated with.Circulating fan 2 can be installed in air channel inlet 3 or ducting outlet 4 places, also can be installed in the air channel 1.
Shown in Fig. 1, adopt the deodorizing sterilizing mechanism that constitutes by photocatalyst 5 and uviol lamp 6, this deodorizing sterilizing mechanism in air channel 1, and with photocatalyst 5 tabulas in air channel 1.In concrete the enforcement, photocatalyst 5 adopts nano material to make, and is mesh-like structure, and its mesh and photocatalyst surface have an angle.Uviol lamp 6 contour structures can be flat, and its flat pattern is similar to the surface plane of photocatalyst, and flat horizontal surface is surperficial substantially parallel with photocatalyst, so that the ultraviolet that uviol lamp 6 sends can be radiated at photocatalyst 5 surfaces to greatest extent.
In concrete the enforcement, device has the circuit board 8 of power circuit and timing control circuit to be fixedly installed on 1 medial wall, air channel by support, and the air channel housing can be made by the ABS material, should be able to shelter from the ultraviolet that uviol lamp sends.
In the use, uviol lamp 6 sends the certain ultraviolet of wavelength, is radiated on the photocatalyst 5, and ultraviolet excites airborne oxygen to produce ozone simultaneously.The surface that can make photocatalyst 5 under the irradiation of ultraviolet and near airborne water and oxygen produce active oxygen and hydroxyl, kill the antibacterial that is adsorbed on photocatalyst 5 surfaces because of air circulation; In the time of with uviol lamp 6 work, fan 2 forces the indoor rancid air admission air channel 1 of containing antibacterial between refrigerator, and after air channel 1, the fresh air that contains ozone and active oxygen is admitted between refrigerator indoor again, so circulate, can reach the purpose of deodorizing sterilizing effectively.
