Implementation of the utility model

The device for sterilization contains a housing 1, inside which there is an ignition and power unit 8, a cyclic timer 9 and a microswitch, the button 4 of which is located on the outer side of the housing 1; in the lower part of the housing 1 is fixed source 3 of ultraviolet radiation; a holder 5 is rotatably fixed on the body 1, containing holes 6 for fixing the device inside the working chamber, and the button 4 of the microswitch is actuated to open/close the door 11 of the working chamber.

As the source 3 of ultraviolet radiation, an ultraviolet lamp with a wavelength of 205 to 315 nm, which can be made shatterproof, can be used. Also, ultraviolet LEDs can be used as a source of ultraviolet radiation. The source of ultraviolet radiation 3 may additionally contain a ceiling made of a material transparent to ultraviolet radiation.

As the ignition unit 8, an electronic ballast (electronic ballast) can be used.

The holder 5 of the device can be attached to the wall 10 of the working chamber with screws, screws, rivets, double-sided tape, etc. or bracket.

The microswitch can be made mechanical or reed switch.

As a working chamber, any structures with doors can be used, for example, kitchen cabinets, including drying cabinets (see Fig. 6-8), as well as boxes of various racks, food storage places, safes, etc. The installation of a more powerful UV source 3 makes the device even more versatile in terms of the amount of protection points.

Assembly and installation of the device for sterilization in the working chamber is carried out as follows.

The holder 5 (see Fig. 3), previously rotated at 90 degrees with respect to the body 1, through its longitudinal holes 6 that have become easily accessible, is attached to the side or top wall 10 of the working chamber using screws, screws, rivets, etc. or bracket. The electric wire coming from it is also brought out of the working chamber through a small round hole previously drilled in it. Then, a UV (C) emitter is inserted into the holder 5, fixed on the body: a lamp or LEDs, and the body 1 is rotated to the optimal position for a particular camera. Then it is firmly fixed with a screw 7 (see Fig. 6-7). This design provides the possibility of smooth rotation of the device within 90 degrees. This rotation allows you to change the direction of ultraviolet radiation and, accordingly, the level and dose of UV radiation. Longitudinal fixing holes 6 allow, after preliminary fixing of the device for sterilization in the chamber, to smoothly move it back and forth. Thus, adjust the position of the on / off button of the microswitch with different devices (doors, drawers, pushers, etc.).

If the working chamber has a non-standard design and dimensions, the holder 5 can first be attached to a bracket (not shown in the figure), which is then attached to the device, providing, among other things, the operation of the microswitch button 4 to open / close the door 11 of the working chamber.

The device for sterilization after its installation in the working chamber is used as follows.

Items and materials for sterilization are placed in the working chamber: dishes, products in transparent bags (for example, delivered by a courier from a delivery service) or without them. Then the door 11 of the working chamber is closed, the sterilization device is turned on, and it begins to sterilize everything that is in the working chamber. The sterilization time is determined by the volume of the working chamber, the power of the radiation source, the volume/number of objects and/or materials to be disinfected and can take from several tens of seconds to several minutes.

The source of ultraviolet radiation 3 is put into operation (ignited) using the ignition unit 8. The radiation source 3 operates according to a certain algorithm, the operation of the ignition unit 8 according to a certain algorithm is controlled by a cyclic timer 9. As soon as the door 11 closes, button 4 closes the electrical contact, and the source radiation 3 is ignited. The sterilization process starts (see Fig. 8).

When the door 11 of the working chamber is opened, the button 4 of the microswitch "departs" and breaks the contact of the timer 9, the device turns off, the UV radiation stops and it is possible to safely get out disinfected objects and materials for the eyes.

The installation of more powerful lamps makes it even more versatile in terms of the volume of protection places.

The cyclic timer 9 of the device is programmable; it can be used to implement, for example, the following mode of operation:

1. Put the objects into the working chamber, close the door 11, the source of UV radiation turned on.

2. After a certain time (for example, 10 minutes), the UV source turned off.

3. After a delay time (eg 2 hours), the UV light source will turn on automatically.

4. After a certain time (the same 10 minutes), the UV source turned off again.

And so the device turns on and off automatically until the next opening of the door 11, after which the cycle repeats (see the description of paragraphs 1-4).

The operation scheme of the timer 9 is constructed in such a way that it is possible to independently change the glow time of the ultraviolet radiation source 3 and the time it is turned off in a very wide range: from several seconds to several days.

Device advantages:

- increasing the ease of installation due to the design features of the holder, which is simply mounted inside the working chamber;

- the possibility of changing the level of UV radiation due to the possibility of rotation of the body of the device, which also provides an increase in ease of use;

- improving security, ease of use, reducing energy consumption by automating the process of turning on / off the device.

Implementation example

An experimental batch of devices for sterilization was made, the photographs (see Fig. 5) show one of them. The experimental device was installed in a kitchen oven (see Fig.6-8). During installation and operation, it was found that the device is convenient to mount, it is simple and convenient to change the level of UV radiation by rotating the body of the device, and it is also safe to use, since UV irradiation occurs only with direct ultraviolet light. Reflected light is not dangerous for human and animal skin. The working chambers can be made, among other things, from opaque materials. By automating the on/off process of the device, power consumption is also reduced.

A comparative analysis of the claimed utility model showed that the totality of the essential features of the claimed device is not known from the prior art and, therefore, corresponds to the condition of patentability "novelty".

The above information confirms the possibility of using the claimed device for disinfection and sterilization of materials, objects, air both at home and in industry, and therefore complies with the condition of patentability "industrial applicability".
