Description

The alleged invention relates to devices for disinfection, sterilization or deodorization of air using ultraviolet radiation and is intended to protect the operator, product and the environment when working with pathogenic agents and microorganisms transmitted by airborne droplets.

A device for air disinfection is known, which contains a housing with inlet and outlet windows with a working chamber and a source of bactericidal treatment, an inlet filter and an outlet fan (RF Patent No. 2306150, IPC Л61Ь 9/20 from 01/26/2006, publ. September 20, 2007).

The disadvantage of this device is the lack of effectiveness of air disinfection.

The technical task of the proposed invention, solved by the authors, is to increase the efficiency of air disinfection, for example, in a laminar box by eliminating the penetration of contaminated air into the working chamber, as well as preventing the entry of contaminated air from the working chamber into the atmosphere.

The problem is achieved in that in an air disinfection device, for example, in a laminar box containing a housing, a working chamber, a blower fan, an air duct, a filter system, a bactericidal treatment source, a control system located outside the device, according to the invention, an upper the chamber where the blower fan is installed, while one panel-type filter, which is connected with the atmosphere, is installed at the inlet, and the other is installed at an angle to the horizontal plane at the exit of the working chamber, both chambers being installed with a gap with respect to the walls of the casing, while the working chamber is equipped with a worktop, and perforation is made on the front of the worktop and on the lower part of the rear panel of the working chamber, the front panel of the working chamber is set at an angle relative to the vertical plane of the housing and the source of bactericidal treatment is placed in the housing on a pull-out panel located under the working chamber.

The side panels of the housing in its upper part are removable.

The front and side panels of the working chamber are made of transparent material.

The lower edge of the front panel is located at a distance from the countertop of the working chamber.

The front panel of the working chamber is installed with the possibility of moving forward and upward with the possibility of fixing in the upper position by means of gas-filled shock absorbers.

A sliding panel with a source of bactericidal treatment is mounted with the possibility of rotation in the vertical plane, and its height in the raised position does not exceed the distance between the lower edge of the front panel and the countertop of the working chamber.

The control system includes a microprocessor system, a display and a touch panel.

Filters are mounted on elastic elements.

The installation in the upper part of the device casing of the upper chamber with a blower fan interacting with panel-type filters, one of which is connected to the atmosphere and the other is installed at an angle to the horizontal plane at the outlet of the working chamber, allows to provide a zone of increased air pressure in the chamber itself and in the associated with it a filter interacting with the working camera. The installation of both chambers, the upper and the working one, with a gap in relation to the walls of the casing, allows forming an air duct with a zone of reduced pressure in relation to the zone of increased pressure in the chambers, which allows creating a flow of air entering the working chamber, i.e. excludes penetration of contaminated air into it. In addition, the presence of a second filter associated with the atmosphere eliminates the ingress of contaminated air into the atmosphere.

The placement of the filter, coupled with the working chamber, at an angle to the horizontal plane ensures the direction of air flow along the front panel of the working chamber, ensures the supply of purified air to the working table.

The presence on the front of the countertop of the working chamber and the lower part of its rear perforation panel provides a connection between the working chamber and the air duct, which contributes to the formation of an air lock, which occurs due to atmospheric air entering the gap between the lower edge of the front panel and the tabletop through perforation into the air duct.

The slope of the front panel of the working chamber relative to the vertical plane of the housing increases the working volume of the camera.

Placing the source of bactericidal treatment on a sliding panel under the working chamber is technologically advanced.

The implementation of the side panels of the housing in its upper part removable allows you to replace the filter elements without disassembling the entire housing.

The implementation of the front and side panels of the working chamber of a transparent material improves visibility in the working chamber, in addition, aesthetically.

Placing the lower edge of the front panel at a distance from the countertop of the working chamber is optimal to ensure the convenience of the operator.

The installation of the front panel of the working chamber with the possibility of moving forward-up provides convenience, for example, during the sanitary treatment of the working chamber, and its fixation in the upper position by means of gas-filled shock absorbers is reliable and safe.

Installing a sliding panel with a source of bactericidal treatment with the possibility of rotation in a vertical plane, with a height in a raised position not exceeding the distance between the lower edge of the front panel and the worktop of the working chamber, allows you to overlap the space between the lower edge of the front panel and the worktop during bactericidal treatment.

The presence of a microprocessor system, a display and a touch panel in the control system allows you to automatically maintain a normalized flow rate in the working chamber, regardless of the degree of contamination of the filters, to monitor parameter changes and to control them outside the device.

The installation of filters on elastic elements makes it possible to eliminate air leaks due to mechanical preloading of elastic elements when the seal is worn between the filters, chambers, and the duct.

As a result of the patent research, no similar technical solutions were identified, characterized by the claimed combination of features, which allows us to conclude that the claimed technical solution has novelty and inventive step, can find application in industry, i.e. is industrially applicable.

The invention is illustrated by drawings, which show:

FIG. 1 - general view of the device;

FIG. 2 is a front view of FIG. one;

FIG. 3 is a side view of FIG. one.

The air disinfection device comprises a housing 1 with removable side covers 2 and 3, a chamber 4, a fan 5, a filter 6, a filter 7, a working chamber 8 with a tabletop 9, perforation 11, an air duct 12 are made on the front of the tabletop 9 and the lower part of the rear panel 10 formed between the walls of the housing 1 by the working chamber 8 and the chamber 4, the front panel 13, which is fixed in the upper position by shock absorbers 14. The device contains a source of bactericidal treatment 15, located in the housing 1 on the sliding panel 16, located under the working to measure 8.

Filters 6 and 7 are mounted on elastic elements (not shown in the figures).

The device also contains a microprocessor control system located outside the device (not shown in the figures).

The device operates as follows.

By the blowing fan 5, air from the atmosphere is pumped into the chamber 4, in which an increased pressure zone is created, and in the duct 12, a reduced pressure zone. From the chamber 4, the purified high pressure air through the filter 7 enters the working chamber 8.

The laminar stream of purified air from the filter 7 enters the working chamber 8 parallel to the front panel 13, providing the necessary parameters of the air environment. The operator has the ability to access the workspace on the countertop 9 through the gap between the lower edge of the front panel 13 and the countertop 9. Monitoring of the work is carried out by the operator through a transparent front panel 13, which is also a means of protecting the operator’s face.

Atmospheric air entering the gap between the lower edge of the front panel 13 and the countertop 9, through the perforation 11 enters the duct 12, which contributes to the formation of an air lock.

At the same time, contaminated air from the working chamber 8 enters through the perforation in the lower part of the rear panel 10 into the duct 12.

From the duct 12, air is again supplied by the fan 5 to the working chamber, and additional volumes obtained from the air lock are removed to the atmosphere through the filter 6.

Thus, the claimed device allows to increase the efficiency of air disinfection, for example, in a laminar box by eliminating the penetration of contaminated air into the working chamber, and also to prevent the entry of contaminated air from the working chamber into the atmosphere.
