Description

DESCRIPTION

Disinfection cabin

TECHNICAL SECTOR

The present invention refers to a disinfection cabinet, which uses ozone to disinfect and eliminate biological hazards from clothing or items worn by the user, without the need to undress and without risk to health.

STATE OF THE ART

In the spring of 2020, a large number of countries suffered from the Covid-19 pandemic. This implied many limitations to the movement of people and great risks of infection, with an appreciable percentage of deaths. Therefore, it became necessary to extremely carefully disinfect personal items when going to work, returning home, etc.

In any case, there are a number of professions that involve similar risks throughout the year: doctor, virology researcher, ... These workers must be able to move with the assurance that they do not become vectors of infections.

Finally, people undergoing medical treatment that causes immunosuppression require the confidence that they will not be infected by their relatives.

Ozone is a highly oxidizing gas that is frequently used in disinfection. Ozone is a gas that has shown, in certain concentrations and application time, a disinfection efficiency of 99%. Ozone is approximately 10-1000 times more effective than other chemicals against bacteria, mold and viruses, sanitation can be completed in just a few minutes, saving significant downtime for any type of installation.

Documents CN104225643 and WO2019144131 disclose large installations for the disinfection of sanitary equipment. They comprise a container to be completely closed for disinfection. Therefore, it is not applicable to clothing or personal items that a user wears without him detaching them.

The applicant does not know of any solution as effective as the one claimed.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a disinfection cabinet according to the claims. Its different embodiments solve the problems outlined and provide notable advantages, obvious to those skilled in the art.

The disinfection cabinet comprises a hollow box, with dimensions to position a part of the user's body: one or both legs, from the waist down or from the neck down. Ozone is introduced into the box by means of an ozone generator. It also comprises one or more apertures, each with a seal. The openings and seals are configured to allow passage of a part of a user's body during use. If the dimensions are sufficient, it can be targeted to multiple users at the same time, but it is less preferred.

The seal can be of different shapes, such as a rubber gasket in the opening, but it is preferred that it corresponds to a waterproof layer arranged outside the box. In this way the cabin can be extended upwards according to the height of the user.

The seal may comprise a part fixed to the case, usually the cape, and a part configured to be arranged around the body of the user. For example, a tapered stretch around the leg, waist, or neck.

The seal can be complemented by an air curtain around the opening. This type of device prevents the diffusion of ozone through the opening.

To shorten the time the user must stay in the cabin, the ozone level can be reduced after the treatment is finished. For this, an ozone decomposition catalyst (commercially available) can be used inside the box. This catalyst will be in a circuit that will be activated when the treatment is finished.

To facilitate access to the cabin, a door can be placed, which preferably can be hermetically closed. However, in one embodiment, the opening is communicated with the door opening, so that the user does not have to bend down when entering to put his head through the opening, but can access directly. In that case, part of the seal may be on the door.

Other variants will be described later.

MODES OF EMBODIMENT OF THE INVENTION

An embodiment of the invention will be briefly described below, as an illustrative and non-limiting example thereof.

The cabin of the embodiment shown in figure 1 comprises a box (1) with at least one opening (2), generally in the upper part. The box (1) can be prismatic or of any other shape, but it must be hollow. For its part, the opening (2) preferably has a seal (3) that can be of different shapes. For example, it can be a rubber or silicone gasket that closes the entire opening (2), a layer that is arranged outside the box (1), or another similar system. In any case, the seal (3) must allow the passage of a part of the body of a user, which depends on the destination of the cabin, and make it difficult for the ozone to escape from the interior if there is no one. For example, the seal (3) can have a catalyst (transition metal oxide, for example) on the outer face of the box (1) as a coating.

The seal (3) can also have two parts, a part fixed to the box and another part that the user places around their body and that is intended to be temporarily attached to the fixed part. This solution helps to adjust the interior space of the cabin for different user heights (figures 1 and 2).

If the cabin is for disinfection of one or both shoes, the user will insert the feet or the foot through the openings (2), leaving the leg outside. If the intended use is to disinfect the entire body, it will be the neck that peeks through the opening, ensuring that the user does not breathe ozone.

Depending on the use of the cabin, the opening (2) may be in communication with a door (4) that can be hermetically closed on the rest of the box (1). The function of the door (4) is to allow the user to enter the cabin.

The cabin has an ozone generator (5) that introduces it inside the box (1). The generator (5) can be corona, UV light ... without being relevant. The ozone thus produced disinfects the inside of the box (1) when the user activates the cabin. Preferably, the generator (5) is oversized to quickly raise the ozone content (for example, up to 80 ppm), but in return a catalyst (6) is available that reduces the amount of ozone when the treatment is finished. This catalyst can be based on transition metal oxides or other suitable metals (eg). The catalyst (6) is preferably associated with a circuit that pumps the air to pass it through the compound.

The generator (5) can be on the floor of the cabin, forming a step, on a wall of the box (1), in a corner.

To reduce ozone leakage through the opening (2), complementing the mechanical seal (3), an air curtain (7) can be installed that closes the passage to gases. This air curtain (7) has its own pumping equipment that takes the air from outside or from the catalyst outlet (6).

The cabin will have its control knob, its power supply and any recommended sensor or timer. For example, you may have ozone sensors inside to monitor concentration, or outside to detect leaks.
