Description

The present invention relates to a means for purifying air that has passed through an air circulation path using radicals and water generated by atmospheric pressure plasma, and an air purifier equipped with IoT.

By electrostatically atomizing water, charged fine particle water containing radicals is generated, and the charged fine particle water is reacted with at least one of ammonia, acetaldehyde and acetic acid, and at least one of the ammonia, acetaldehyde and acetic acid. Is characterized by decomposing.

Taking advantage of such characteristics, JP-A-2014-131765 discloses an example in which water is electrostatically atomized to generate charged fine particle water containing radicals and decompose odor.

In addition, suspended airborne bacteria introduced into the air purifier are taken in by a cleaning liquid containing a bactericide, and the cleaning liquid is collected in the intake area of the storage tank and used to clean the contaminated water. It has been shown that it is necessary to suppress the amount of germicide used, such as discharging a part of the liquid and injecting a diluting liquid to dilute the cleaning liquid.

However, in conventional air purifiers, the generated radicals are chemically unstable and highly reactive, and as soon as they are generated, they undergo an oxidation-reduction reaction with other atoms and molecules to form stable molecules and ions. However, it is extremely difficult to diffuse radicals into the space in the room to obtain the effect of air purification.

In addition, some conventional air purifiers have an air purifying mechanism inside, and there are types that generate radicals and purify air, and types that use bactericides, but types that generate radicals and purify air. In the case of, there is no change in the components that should be eliminated by the reaction with radicals such as carbon monoxide and acetaldehyde, and there is a problem that the type using a bactericide has a very high risk of causing a great adverse effect on the human body. is there.

The present invention is to provide an air circulation path and an air purifying space in an air purifier, and to effectively utilize the characteristics of radicals to replace the air in the indoor space with safer and more reliable clean air. At the same time, it aims at accumulating practical data in order to deal with air pollution, which is a problem of the present society, and watching over the safety of the lonely lives of the elderly.

The first invention is an air purification means for purifying air passing through an air circulation path and an air purification space, a discharge device for generating atmospheric pressure plasma, a water storage tank for introducing radicals generated by discharge, a human sensor, and the like. It is premised on an air purification processing device equipped with a detection sensor and a communication control device for an IoT device.

In the first aspect of the present invention, radicals generated by discharge in a discharge device that generates atmospheric pressure plasma are rapidly charged into a water storage tank to electrostatically atomize water, thereby generating charged fine particle water containing radicals. However, it reacts with at least one of carbon monoxide, ammonia, acetaldehyde, and acetic acid to decompose at least one of the ammonia, acetaldehyde, and acetic acid, and radicals such as harmful substances contained in the air or water. It is decomposed and removed to sterilize.

Further, in order to ensure stable discharge of the discharge device for generating atmospheric pressure plasma, the same amount of air as that to be supplied to the water storage tank is supplied.

In the first aspect of the present invention, since no substances are decomposed and returned to the room at all, a filter group is provided in the discharge path of the air removal space, and the filter group is composed of a prefilter, a high-performance HEPA filter, an activated carbon filter, etc. It is characterized by being present.

In the present invention, by rapidly atomizing water by radically generating radicals generated by discharge in a discharge device that generates atmospheric pressure plasma into a water storage tank, to generate charged fine particle water containing radicals, React with at least one of harmful substances such as carbon monoxide, ammonia, acetaldehyde and acetic acid to decompose at least one of the ammonia, acetaldehyde and acetic acid, and also to remove harmful substances contained in the air or water. Since it is decomposed and removed by radicals and sterilized, it is possible to provide clean and clean air in the room with safe and secure air cleaning without fear of adversely affecting the human body.

INDUSTRIAL APPLICABILITY The present invention is capable of instantaneously transmitting the sensing information of various sensors to the central database by the communication control device of the IoT device and accumulating practical data in order to respond to air pollution which is a problem in the present society. In the case of a person or Shinobu Hitokura, the movement in the room where the air purifier of the present invention is placed can be confirmed in real time, so the safety of the lonely life of the elderly can be watched.
