The essence of the proposed utility model is as follows.

The device for disinfection includes a housing in which a working chamber is formed and sources of ultraviolet radiation are installed, while in the lower part of the housing under the bottom of the working chamber there is a cavity communicated with the working chamber through holes made in the rear wall of the working chamber, located with a gap relative to the rear wall housings, and the sources of ultraviolet radiation are made in the form of bactericidal lamps installed in the upper part of the working chamber and in the cavity under the working chamber, inside which a removable means for placing disinfection objects is fixed, while the working chamber is made with a hinged front cover.

Sources of ultraviolet radiation are made in the form of at least one ozone lamp with a wavelength of 185 nm, fixed in the cavity under the working chamber, and at least one ozone-free lamp with a wavelength of 253.7 nm, fixed in the upper part of the working chamber.

A fan is installed in the cavity under the working chamber.

The case contains a control board for operating modes of the device.

Replaceable means for placing disinfection objects is made in the form of a folded zigzag tape, or in the form of rods vertically located in the working chamber; or in the form of vertically or horizontally arranged lattices.

The essence of the utility model is illustrated by: figure 1, which shows a diagram of the general view of the claimed device for disinfection (without the front cover); Figures 2 - 6, which show variants of execution of means located inside the device for placing objects of disinfection.

The device for disinfection includes a housing 1, inside of which a working chamber 2 is located, under which a cavity 3 is formed in the device housing, communicated with the working chamber 2 through holes 4 made in the rear wall of the working chamber 2, located with a gap relative to the rear wall of the housing 1. В cavity 3 and in the upper part of the working chamber 2 installed sources of ultraviolet radiation 5,6.

Sources of ultraviolet radiation are made in the form of at least one ozone lamp 5 with a wavelength of 185 nm, fixed in the cavity 3 under the working chamber, and at least one bactericidal lamp 6 with a wavelength of 253.7 nm, fixed in the upper part of the working chamber. cameras.
