Then enters the field electric module 13, and in the field electric module 13, the electric field force further inactivates bacteria and viruses in the air to obtain a better sterilization effect, and meanwhile, the particles with charges can be adsorbed, so that the particles are collected in the field electric module 13. Thus, the air without bacteria, viruses and particles comes out of the disinfection and sterilization device 1 and reaches the evaporator, and then enters the indoor space after the temperature of the air is adjusted by the evaporator, so that the air quality of the indoor space can be better improved.
The utility model provides an air conditioner indoor unit, which is provided with the disinfection and sterilization device.
The indoor unit of the air conditioner comprises a shell, wherein the shell is provided with an air inlet, and a disinfection and sterilization device is arranged in the position, close to the air inlet, in the shell.
It should be noted that, the indoor unit of an air conditioner has all the technical effects of the disinfection and sterilization device described above, and details are not described herein.
In summary, in a preferred embodiment of the present invention, the sterilization device 1 includes a plasma sterilization module 12 and a field module 13 disposed along an air flowing direction, air is first ionized by the plasma sterilization module to generate plasma, so as to remove bacteria and viruses in the air and make the particles charged, and then the air enters the field module 13, and the bacteria and viruses in the air are further removed by an electric field force of the field module 13, and the particles charged are adsorbed, so that the bacteria and viruses in the air can be removed and the particles in the air can be removed at the same time through a synergistic effect of the plasma sterilization module 12 and the field module 13, thereby improving user experience. The plasma sterilization module 12 includes a plurality of sets of first and second portions 121 and 122 disposed in a matching manner, and at least a portion of the first portion 121 is disposed through the through hole 1221 of the second portion 122 disposed along the axial direction thereof, so that when the first and second portions 121 and 122 are energized, an electric field is formed between the first and second portions 121 and 122, and the electric field can ionize air to generate plasma. The field module 13 includes a plurality of pairs of electrode pairs, each pair of electrode pairs includes a negative electrode 132 and a positive electrode 131, which are oppositely disposed and are disposed in a plate-shaped structure, and a second support rib 133 is disposed between the adjacent negative electrode 132 and positive electrode 131, so that while the negative electrode 132 and positive electrode 131 are stably disposed, a better sterilization effect is obtained, more particles are adsorbed, and the air flowing through the sterilization device 1 is purer.
Of course, the above alternative embodiments, and the alternative embodiments and the preferred embodiments can also be used in a cross-matching manner, so that a new embodiment is combined to be suitable for a more specific application scenario.
Furthermore, those skilled in the art will appreciate that while some embodiments described herein include some features included in other embodiments, rather than other features, combinations of features of different embodiments are meant to be within the scope of the utility model and form different embodiments. For example, in the claims of the present invention, any of the claimed embodiments may be used in any combination.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the utility model, and the technical scheme after the changes or substitutions can fall into the protection scope of the utility model.
