RU2275209C1 - Fan-type air ionizer - Google Patents

Abstract

FIELD: medical engineering.

SUBSTANCE: air ions are produced when combining electrons with molecules in the air in horizontal cylindrical air duct around fan blades. When issued into free space, electrons rush upward under vertical terrestrial electrical field at speed of 1000 m/s and air ionization takes place near the ceiling. To make air ionization take place in the whole fan air duct volume, thin aluminum layer is available in air duct walls. The device has fan, air duct and needle-shaped electron radiators mounted on dielectric fan blades. Power supply source has transformer increasing alternating public current voltage and delivering to the needle-shaped radiators via restrictive resisters. The cylindrical air duct is screened from the terrestrial electrical field influence by means of thin aluminum layer available in its walls.

EFFECT: small-sized ionizer possessing features of producing and supplying ionized air into living or working rooms.

Description

The invention is an air ionization device and can be used in everyday life, medicine, agriculture and other cases to improve the well-being of people and increase labor productivity.

Known air ionizer (copyright certificate 615938, class A 61 No. 1/44, publ. 06/19/1978). This device cannot produce ions, because in it, electrons cannot get onto the needles placed inside ring 8. (It is known that charges in conductive bodies are distributed only on external surfaces). Electrons from the needles are not emitted, and air is not ionized. This device is not an analogue of the invention.

Known aeroionizer (description of the invention 827079, class A 61 No. 1/44, publ. 05/07/1981). It mistakenly claims the formation of ions near the edges of the metal fan blades, which is impossible, because Electrons can only drain from the ends of the needles. And the ions formed near the needle cathode placed inside the diffuser are neutralized on this diffuser, because it has a high positive potential. This ionizer is a prototype of the device proposed in this invention.

Known ionizer of air oxygen (description of the invention RU 2126277 from 20. 02. 1999). In it, the electrons emitted from the cathode needles, under the action of the vertical electric field of the Earth, acquire a speed directed upwards. Most electrons adhere to the upper wall of the duct and are not involved in ion formation. Thus, this device does not produce ions.

In conclusion, it is necessary to point out that there are ionizers of various designs on sale in Russia, but there is not one that takes into account the effect of the electric field of the Earth, and therefore they are all completely useless or, at best, have a very low efficiency.

This is the state of the technology of aeroionization by 2005.

The objective of the invention is to provide a compact ionizer capable of not only ionizing air, but also supplying it to consumers in a residential or working room.

The task is achieved in that:

1) needle emitters are placed on dielectric fan blades;

2) the power supply is represented by a simple transformer;

3) the duct, which is the ionization zone, is mounted on the fan;

4) the fan creates an air flow;

5) a thin layer of aluminum is introduced into the walls of the duct to protect electrons and aeroions from the action of the Earth's electric field.

Until now, the negative potential of direct current has been supplied to the needles of the electron emitter, therefore the power supply unit contained short-lived electronics in the rectifier. The present invention provides a power supply unit from a long-life transformer without a rectifier, powered by an AC mains. The possibility of this is explained very simply: although the runoff of electrons will not occur continuously, but only in half-periods, when the negative potential is applied to the needles, and the formation of ions will be periodic with a frequency of 50 Hz, but this will be completely invisible to consumers in the flow of ionized air .

The ionizer works as follows. The power is supplied from a 220 V network. In transformer 2, the alternating current rises to 10 kV and, through the limiting resistance R = 10 ⁶ Ohms, is supplied to needle emitters of electrons located on the dielectric fan blades. Electrons flowing from the ends of the needles enter the air stream in a 30 cm long duct. Since a thin layer of aluminum 7 is introduced into the three-layer dielectric walls of the duct, its volume is protected from the Earth’s electric field. Electrons move along the duct and ionize the air flow without interference. The stream of ionized air coming out of the duct goes to a residential or working room.
