As shown in Fig. 1 to Fig. 6 and Fig. 9, the clean air cooling and heating machine of the present invention includes a blower part 100, an air processing part 200 and a circuit part. in:

The blower part 100 includes a turbocharged vortex air supply device and a guide air outlet device.

The turbocharged vortex blower includes a casing 18, a compression chamber casing 19 arranged in the casing 18, a turbine 15 arranged at the air inlet end of the compression chamber casing 19, a motor 16 connected to the turbine 15 and driving the turbine 15, and a motor 16 connected to the compression chamber. The air outlet guide cover 17 of the air outlet end of the shell 19.

The guide air outlet device includes an annular curved surface shell 20 with one end closed and the other open (consisting of an inner shell and an outer shell, which can obtain ideal inner curved surface shape and outer curved surface shape). shape, elliptical column shape, trumpet shape, waist drum shape, etc. The annular curved shell 20 includes an air inlet port arranged on its annular side, and the air inlet port is connected with the air outlet side of the turbocharged vortex blower housing 18 . The airflow direction of the hot and cold machines is shown by the arrows in Figure 5.

The air handling section 200 includes the housing 14 and an air handling device. The housing 14 includes an air inlet a and an air outlet b arranged at intervals, and the air handling device is arranged inside the housing 14 and is located between the air inlet a and the air outlet b.

The air treatment device includes a first filter device 8, a nano filter element filter device 11 and an ultraviolet disinfection lamp 12 (ultraviolet UV lamp).

The first filter device 8 is arranged at the air inlet a to block the entire air inlet area of the air inlet a, and the air outlet b of the casing 14 is connected to the air inlet side of the casing 18 of the turbocharged vortex air supply device. The nano-filter element filter device 11 and the ultraviolet disinfection lamp 12 are sequentially arranged behind the first filter device, the nano-filter element filter device 11 blocks the entire air inlet area, and the ultraviolet disinfection lamp 12 is adjacent to the air outlet b.

The first filter device 8 filters suspended matter in the air such as dust, hair, pollen and the like. The oxides decomposed by the nano-filter filtering device 11 can convert peculiar smells and pollutants into substances harmless to the human body, and meanwhile the nano-filter absorbs smoke to eliminate peculiar smells in the air. The ultraviolet sterilizing lamp 12 utilizes C-band (254nm) long ultraviolet light waves to destroy the internal structure of viruses and bacteria that cannot be filtered and adsorbed in the air, thereby achieving the effect of killing viruses and bacteria.

As shown in Figures 7 and 8, in order to prolong the residence time of air in the irradiation area of the ultraviolet disinfection lamp 12 and improve the disinfection and sterilization effect of the ultraviolet disinfection lamp 12, a slow flow cover 142 is provided. The slow flow cover 142 includes a bottom plate and an annular side connected to the bottom plate. The slow flow cover 142 is connected to the inner surface of the casing 14 with the annular side, and is located below the air outlet b of the casing 14, forming a bottom plate and an annular side of the slow flow cover.

The annular side of the slow flow cover 142 comprises the air inlet 142b facing away from the nano-filter filter device 11, so that the air passing through the nano-filter filter device 11 must flow around in the irradiation area of the ultraviolet disinfection lamp 12 and then enter the slow air from the air inlet 142b. The flow cover 142 enters the air inlet end of the turbocharged vortex air supply device compression chamber housing 19 through the air outlet b of the housing 14, so as to prolong the air passing through the nano filter element filter device 11 in the housing 14 where the ultraviolet disinfection lamp 12 is set dwell time in the cavity.

In order to avoid that most of the filtered air that flows into the inner chamber of the housing 14 through the nano-filter element filter device 11 enters the slow flow cover 142 through the air inlet 142a, so that the residence time of most of the air in the inner chamber of the housing 14 is short, which cannot meet the requirements of improving the ultraviolet disinfection lamp 12. Requirements for disinfection and sterilization effect, on the annular side of the air inlet 142a, the slow flow cover 142 is provided with an isolation edge that surrounds the air inlet 142a and extends to the surface of the air outlet side of the nano-filter element filter device 11, and the isolation edge will pass through the nano-filter element in its inner side The filtered air of the corresponding part of the filter device 11 is isolated from the filtered air of the corresponding part of the nano filter element filter device 11 outside it, and under the premise of meeting the air flow demand of the turbocharged vortex air supply device, it is guaranteed that most of the air meets The requirement of the disinfection residence time in the inner cavity of the shell 14 improves the disinfection and sterilization effect of the ultraviolet disinfection lamp 12 .

Because electrons cannot exist in the air for a long time (the lifetime of electrons in the air is only ns), but will be captured by oxygen molecules (O ₂ ) in the air immediately to form negative oxygen ions, which are rich in oxygen that is beneficial to human health. Air with negative oxygen ions.

In order to further improve the quality of air treatment, the air treatment device of the present embodiment is provided with a photocatalyst material, which is arranged on the inner surface of the housing 14 that can be irradiated by the ultraviolet disinfection lamp 12 . When the ultraviolet sterilizing lamp 12 lights up and irradiates on the photocatalyst material on the inner surface of the shell 14, free electrons and holes are generated, various organic compounds and some inorganic substances are oxidized and decomposed, and the cell membrane of bacteria is destroyed and the protein of solidified virus is thereby Further purify the air.
