Description
Technical Field
The utility model relates to a new equipment of toilet type.
Background
A clean room is a room that controls the concentration of atmospheric particulates and adequately controls other relevant parameters (e.g., temperature, humidity, and pressure), and is constructed and operated to minimize the introduction, generation, and retention of particulates within the room.
In other words, a clean room refers to a room in which air pollution caused by suspended particulate matter is controlled in terms of particle size and number of particles per cubic meter of air. There are several types of such contamination: particulate contamination, microbial contamination and/or chemical contamination. The ISO 14644 standard defines a clean room grade based on the number of particles of a given size.
Such a clean room is used in particular in hospital departments for protecting patients.
This type of installation can now also be applied to protect outdoor air from contamination by indoor activities. We then talk about "sealing" the room, which is then under negative pressure (lower pressure) with respect to the outside to ensure that the internal contamination of the room remains closed (sealed) within the room.
Such clean rooms are usually installed inside buildings and are permanent buildings made of building materials. This reduces its mobility.
However, there is a need to be able to have such a clean room in a variety of indoor and outdoor environments without having to be built or prepared for this purpose. A clean room that is simple, quick to assemble, implement and/or disassemble is particularly valuable for all casual, emergency or temporary uses.
SUMMERY OF THE UTILITY MODEL
The inventors have now developed a clean room whose simplified structure in combination with a mobile filter unit allows for ease of installation and management.
Accordingly, the present invention relates to a clean room having at least one volume delimited by partitions associated with each other and attached to the ground and possibly to at least one wall of a building, comprising:
-at least one entrance door;
-at least one Fan Filter Unit (FFU);
-at least one opening associated with the filter;
-at least one pressure sensor within a volume of the clean room; and
-at least one microcontroller allowing to adjust at least one FFU according to the pressure value measured by the at least one pressure sensor in order to obtain a desired pressure within the volume of the clean room;
it is characterized in that the clean room does not comprise any air circulation duct in its ceiling, but the clean room comprises:
-at least one second opening, to which the FFU is connected by a ventilation connection, the FFU being a mobile FFU adjacent to the clean room.
-at least one connection means for connecting the FFU to a microcontroller responsible for its regulation.

The entrance door 13 is preferably made of a transparent material, preferably glass (e.g., safety glass).
The entrance door 13 helps to keep the clean room air-tight from the outside.
Now, as long as the clean room is under positive or negative pressure, air exchange must still be performed between the clean room and the external space.
In this case, the opening 19 associated with the filter allows the air to be depressurized when the clean room is in a positive pressure state or allows the air to be supplied when the clean room is in a negative pressure state.
The filter used must be thick enough to allow effective air filtration. In general, the thickness of such filters is between 10 and 100mm, preferably between 20 and 80mm, particularly preferably between 40 and 60 mm.
According to a first particular embodiment, the clean room is under negative pressure, then the clean room is characterized by:

According to a particular embodiment, the clean room according to the invention comprises two openings, each associated with a filter, wherein the closing of one of the openings depends on whether the clean room is selected to be placed under a positive or a negative pressure.
The fan Filter assembly is known in the art as an FFU (Fan Filter Unit). They consist of an air overpressure and at least one filter.
Air overpressure devices are well known and include, in particular, fans and turbines. Preferably, such air overpressure device is a turbine.
Generally, the means for over-pressurizing the air of the mobile FFU20 of a clean room according to the invention enables air at 200 to 5000m3H, preferably between 500 and 2000m3An operating flow rate of between/h enters the FFU and exits therefrom.
In case the clean room is at a positive pressure, the means for overpressure of the air of the mobile FFU20 allow to generate a positive pressure of 3 to 50Pa (relative to the outside of the clean room), preferably of 5 to 30Pa (relative to the outside of the clean room), particularly preferably of 10 to 20Pa (relative to the outside of the clean room).
In the case of a negative pressure of the clean room, the means for overpressure of the air of the mobile FFU20 allow a negative pressure of 3 to 50Pa (relative to the outside of the clean room), preferably a negative pressure (relative to the outside of the clean room) of 5 to 30Pa, particularly preferably a negative pressure of 10 to 20Pa (relative to the outside of the clean room) to be generated.

Advantageously, the mobile FFU further comprises an ionizer.
Typically, such an ionizer may take the form of at least one corona effect plasma cell comprising a substantially needle-shaped polarizing electrode and a ground electrode disposed opposite the polarizing electrode, comprising a substantially central cylinder on the polarizing electrode and a substantially planar porous membrane perpendicular to the polarizing electrode. Such an ionizer is described, for example, in european patent application EP3613264a 1.
Such an ionizer is therefore capable of generating a plasma that passes through the air flow, thereby electrically charging the particles present in the air, so that the particles remain in the at least one electrostatic filter.
Preferably, traveling FFU20 also includes an electrostatic filter associated with the ionizer.

Other features, details and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with fig. 1-4:
fig. 1 shows a clean room under negative pressure, with one of the ceilings 10 having an opening associated with a filter, which allows air to enter the clean room (black arrows). Then, the air entering the clean room passes through an opening at the bottom of one of the clean room sidewalls before reaching the traveling FFU20, and is then discharged to the outside. In addition to the ceiling 10, the clean room is delimited by side panels (clean room panels), some of which 11 may have openings (windows) 12. The clean room is accessed through a door that is automatically opened by a door open button 14 located beside it, under which a touch screen informs the operator about the operating parameters of the clean room, which the operator can modify. Finally, the clean room comprises an electrical cabinet 15 to which all clean room equipment/systems are connected.
Fig. 2 shows a vent connection 21 that allows a mobile FFU20 to be connected to the second opening 16 of one of the clean room sidewalls under negative pressure.
Figure 3 shows a clean room under positive pressure. It can be seen that air drawn in from the bottom of traveling FFU20 re-enters through opening 19 at the top of one of the sidewalls and then exits the clean room through an opening located lower down at the bottom of one of the clean room sidewalls.
As shown in fig. 4 and 3, the ventilation connection 21 allows for the attachment of a mobile FFU20 under positive pressure to an opening at the top of one of the cleanroom sidewalls.
