Detailed Description

First, it should be noted that the following embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present invention. It will be understood by those skilled in the art that the present invention may be practiced without some of these specific details.

In the description of the present invention, the terms "inside", "outside", "top", "bottom", and the like, which indicate directions or positional relationships, are based on directions or positional relationships in practical use, which are merely for convenience of description, and do not indicate or imply that the claimed apparatus must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In addition, in the present invention, "not labeled" indicates that the corresponding structure is illustrated but not labeled, and "not illustrated" indicates that the corresponding structure is not shown.

In order to better understand the technical solution of the present invention, the following first explains the construction of the ionizer and the sterilization principle.

The ionizer of the present invention is a positive and negative ion generator, which can simultaneously generate positive and negative ions as the name implies. The positive and negative ion generator has a positive ion generating electrode connected to a positive high voltage and a negative ion generating electrode connected to a negative high voltage, and the electrodes are usually tungsten needles or graphite electrodes. When the two electrodes are electrified, corona is generated between the two electrodes, outer layer electrons of certain atoms in the air are separated from the orbit to become free electrons under the action of the corona, and the atoms losing the electrons are in positive polarity; the free electrons are negative-electrode, and because the separated free electrons cannot independently exist in the space for a long time, the free electrons can be combined with other nonpolar molecules in the air, so that the part of gas molecules obtaining the electrons are negative-electrode (for example, negative oxygen ions are generated), and the process is called air ionization. When negative ions in the air are combined with microbes such as bacteria and viruses in the air, molecular protein structures of the microbes such as the bacteria and the viruses can be damaged, structural change or energy transfer is generated, and therefore the microbes such as the bacteria and the viruses die, and the sterilization effect is achieved. Therefore, the ion sterilization has a better sterilization effect than the ultraviolet sterilization because the positive and negative ions generated by the ion generator can be diffused to any indoor area along with the air outlet of the air conditioner, thereby achieving the indoor omni-directional sterilization.

The ion generator of traditional air conditioning indoor set configuration generally sets up in the air outlet of indoor set, receives the influence of air outlet department structure, and the user can't observe the position of ion generator very conveniently or very directly perceivedly, and also can't learn the running state of ion generator in the ion generator operation process, to some users, probably can be doubtful to the normal operating of the function of disinfecting of air conditioning indoor set, is unfavorable for the user to use the product with putting one's mind at rest, and then influences user experience.
