JP3069676U - Moisture removal ventilation fan - Google Patents

Abstract

(57) [Summary] [Purpose] Automatically detect indoor and outdoor humidity, automatically flow only dry air into the room, and perform ventilation to remove moisture without human intervention. Prevents moisture, mold, odor, corrosion and aging. [Structure] The indoor and outdoor humidity is detected by an outdoor humidity detector and an indoor humidity detector, and a ventilation fan is automatically operated and stopped by a control switch.

Description

[Detailed description of the invention]

[0001] The present invention is a ventilation system that automatically detects indoor and outdoor humidity, and allows only dry air to flow into a room without any person. By installing this ventilation system, dry air is sent into vacant condominiums and apartments, villas, warehouses, and newly-built buildings when not present.・ We can prevent from aging.

[Prior Art] [0002] In the conventional ventilation method, even when a ventilation fan is manually operated each time or a ventilation fan is automatically activated, the ventilation fan is turned on and off at a certain time by a time switch. Off. Alternatively, the ventilation fan can be activated only when a certain level of humidity is detected, requiring manual operation each time, and no consideration is given to the relative humidity inside and outside the room. In terms of moisture removal, it was inconvenient and incomplete ventilation.

[Problems to be Solved by the Invention] If the room is moist, mold and bad smell are generated, and buildings and facilities are easily corroded and deteriorated. To prevent these, it is necessary to keep the room dry. For that purpose, ventilation is necessary, but in this ventilation, only air that is dryer than the current room air must flow into the room. To ensure this, it is necessary to detect indoor and outdoor humidity and ensure that ventilation is provided only when the outdoor humidity is lower, and that this is done automatically.

[Means for Solving the Problems] In the present invention, a humidity detector (1) is installed outside the room, and a humidity detector (2) is installed inside the room to detect the humidity inside and outside the room. (3) Activate the ventilation fan (4) only when the outdoor humidity is low or equivalent, and when the indoor humidity becomes lower than the outdoor, the control switch suspends the operation of the ventilation fan and always keeps the indoor Only air that is dry than the air in the room should be allowed to flow into the room. In this case, the inflow of the dried air may be performed by a ventilation fan, or the ventilation fan may exhaust the air to allow the dried air to flow from another place.

[Operation] The control switch activates the ventilation fan only when the humidity inside and outside of the room is detected by the respective humidity detectors and the humidity of outside of the room is lower than that of the room and it becomes necessary to ventilate the room. If the humidity outside the room is higher than inside the room, do not operate the ventilation fan to keep the outside moisture out of the room. Therefore, if the air outside the room is dry than the room, ventilation is performed, and if the air inside the room is dry from the outside, no ventilation is performed. Generation of mold and odor, corrosion and aging can be prevented.

Embodiment 1 FIG. 1 shows an outdoor humidity detector (1), an indoor humidity detector (2), a control switch (3), a ventilation fan (4), and a ventilation fan equipped with an electric plug. It is an overall view. Embodiment 2 FIG. 2 shows a case where indoor and outdoor humidity detectors (1) and (2), a control switch (3), and a ventilation fan (4) are mounted on a panel (5), and this panel is installed on a window frame. This is an embodiment when the air outside the room is more dry than the room. The ventilation fan operates to provide ventilation. FIG. 3 is a cross-sectional view, in which dry air outside the room is flowing into the room. Example 3 FIG. 4 shows a case where humidity detectors (1) and (2) and a control switch (3) are installed inside and outside the room and an existing ventilation fan is used, and when the indoor air is dried from outside the room. This is an embodiment of the present invention. Ventilation fan shuts off and does not ventilate. FIG. 5 is a sectional view thereof.

[Effects of the Invention] According to the present invention, even in an unmanned room, ventilation for removing moisture can be automatically performed without any human intervention, and the generation of mold and odor due to the humidity in the room, and corrosion.・ Aging can be prevented.
