Benefits of technology
This patent is about a device that can refresh air in a confined space before the door is opened. The device includes a fan to remove harmful vapors, pollution, and humidity from the air inside the space. The device also has a means to open and close the door, with the door remaining locked while the fan is running and being unlocked after the fan is stopped. The device may also have a purifier to clean the air before it is released from the space. The technical effect of this device is to provide a fresh, healthy air supply in a safe and easy way.
Problems solved by technology
Some of these products present various dangers such as fire, explosion and health risks.
At the end of the washing cycle, when the doer is opened, a large quantity of hot steam exits the machine, which is a disadvantage for the operator, ail the more so if the room contains several dishwashers located side by side and which operate at the same time.
In addition, the operator is subjected to the release of hot steam which may contain harmful substances that come from the washed glassware.
As the compressor is forced to run almost permanently—an operation for which it was not designed—its service life is considerably reduced.
In addition, the associated energy consumption is exceedingly high.

Embodiment Construction
[0016]With reference to FIGS. 1 and 3, the air renewal device 10 or 110 according to the invention is integrated into an enclosure 12, for example by being fixed to the door of the enclosure or on one of its walls. The air contained in the enclosure contains harmful vapours and / or pollutants and / or moisture and is referred to as “charged air” in the following description.
[0017]The air renewal device 10 or 110 comprises an exhaust duct 14 requiring that a hole be made in the wall of the enclosure 12 for discharging the charged air contained inside the enclosure.
[0018]The exhaust duct 14 has an opening damper 16 which allows the charged air to be discharged from the enclosure when the duct is open as shown by the arrows 13 and 20. A ventilation means, such as a fan 22, is started after the damper 16 is opened, causing the charged air to be discharged from the enclosure. The air renewal device also includes a means for purifying the discharged air, that is to say, to make it healthier....

Device (10, 110) for renewing air in an enclosure, including a discharge means (14) for the air inside the enclosure containing harmful vapors and / or polluted air and / or humidity, a fan (22) being located within the discharge means and being suitable to convey this inside air through the discharge means, and a means (26) for opening the door of the enclosure that makes it possible to lock and unlock the door, the unlocking of the door being subsequent to a manual or automatic opening command from an opening control means, the door remaining locked when the opening means is activated, its deactivation being performed after unlocking conditions are met. The device additionally includes at least a means (17, 27) for purifying the air before it is evacuated through the exhaust duct.
Description
TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to devices and methods used for the renewal of vapours and / or polluted air contained in a closed confined space such as a refrigerator intended to contain products releasing such vapours and / or polluted air, or a dishwasher intended for cleaning the containers for these products, and in particular, relates to a device for renewing air in a confined enclosure.BACKGROUND ART[0002]In a laboratory, products that must be kept at temperatures below room temperature are stored in refrigerators. Some of these products present various dangers such as fire, explosion and health risks. They can sometimes release substances that are harmful to users who repeatedly inhale them each time the refrigerator is opened.[0003]It should be remembered that, according to the National Institute for Research and Security (INRS), a chemical laboratory in which operations are carried out with products emitting vapours or gases, and the refrig...
