Detailed Description
In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.
The utility model discloses a disinfection structure and air purifier include filter screen 1 and heater 2, and filter screen 1 adopts HEPA high efficiency filter screen, preferably is H13 high efficiency filter screen, can effective filtering bacterium, virus, gas capacity glue etc.. The heating wire 2 is woven by adopting a thin resistance wire to form a net shape, the resistance wire is vertically and horizontally staggered and uniformly distributed, and a cofferdam 7 is arranged around the net-shaped resistance wire, so that the heating wire 2 is enclosed into a box shape, and the cofferdam 7 is made of a high-temperature-resistant insulating material. The filter screen 1 is sleeved inside the box-shaped heating wire 2, the lower surface of the filter screen 1 is tightly attached to the upper surface of the heating wire 2, and the heating wire 2 is uniformly distributed on the lower surface of the filter screen 1.
7 one end in the cofferdam of heater 2 is provided with PLC thermostatic control 4, and PLC thermostatic control 4 passes through and is connected between thermostatic control connecting wire 5 and the heater 2, and last switch-on power supply line 3 of PLC thermostatic control 4, power supply line 3 are the power supply of PLC thermostatic control 4.
The temperature sensor 6 is arranged in the heating wire 2, the temperature sensor 6 is uniformly distributed on a resistance wire of the heating wire 2, the temperature sensor 6 transmits the real-time temperature on the surface of the filter screen 1 to the PLC constant temperature controller 4 through a constant temperature controller connecting wire 5, when the surface temperature of the filter screen 1 is higher than a set value, the current of the resistance wire is reduced under the action of the PLC constant temperature controller 4, the heating value of the resistance wire is reduced, the heat is pumped away under the action of a fan at the top of the air purifier, and the surface temperature of the filter screen 1 is reduced; when the surface temperature of the filter screen 1 is lower than a set value, the current of the resistance wire is increased under the action of the PLC 4, the heat productivity of the resistance wire is increased, and the surface temperature of the filter screen 1 is increased.
In order to facilitate the replacement of the filter screen 1, the heater 2 and the filter screen 1 are detachably designed, and the heater 2 is taken down and a new filter screen 1 is arranged when the filter screen 1 needs to be replaced.
When the air purifier starts a disinfection mode, the heating wire 2 starts to work, so that the filter screen 1 generates high temperature and generates heat, the constant and uniform temperature field on the surface of the filter screen 1 is realized through the accurate control of the PLC 4, the temperature range is set to be 56-70 ℃, and bacteria and viruses are killed based on the high-temperature disinfection principle. Besides the air purifier, the disinfection structure can also be used for other household appliances with disinfection and sterilization structures, such as a disinfection machine.
The utility model discloses a disinfection structure and air purifier realize the self-heating of high-efficient filter screen, reduce thermal loss, can effectively reduce complete machine power, and heater evenly distributed can save complicated control logic at the filter screen lower surface in addition, and swift realization filter screen lower surface temperature field is invariable and even, can high-efficiently eliminate bacterium and virus.
