AI Technical Summary
Existing ventilation systems fail to maintain indoor comfort by adjusting humidity levels, leading to discomfort in both new and existing buildings due to the supply of humid or dry air, and additional electricity costs from separate dehumidifiers and humidifiers.
A device that integrates silica gel with a humidity control function at the air intake port of ventilation equipment, allowing air to pass through multiple layers of mesh covered by a casing, absorbing and releasing moisture to adjust humidity without additional electricity.
Enables comfortable indoor conditions by adjusting humidity levels without electricity costs, applicable to both new and existing buildings, and effectively controls odors.

Abstract
Description
[Technical Field]
[0001] The present invention relates to a device for supplying clean air from the outside into a house after adjusting its humidity. [Background technology]
[0002] The 2003 amendment to the Building Standards Act (enforcement of the Sick House Law) made it mandatory for all buildings to have 24-hour ventilation equipment installed. While ventilation does eliminate formaldehyde from indoor spaces, which is the purpose of the Sick House Law, it also supplies humid air in the summer and dry air in the winter, reducing indoor comfort. Therefore, there is a need for technology that can adjust the humidity of the supplied air while ventilating, and maintain indoor comfort even with ventilation. Prior Art
[0003] There is a housing system called the First Method, in which ventilated intake air is purified using an air purifier equipped with an electronic dust collection filter, and the purified air is mixed with hot and cold heat from an air conditioner and forced under the floorboards using a blower, where humidity is controlled under the floorboards and cold heat is stored throughout the house by circulating air through the exterior skin. Summary of the Invention [Problem to be solved by the invention]
[0004] Prior art technology has the problem that it can only be used in new construction projects.
[0005] In addition to ventilation equipment, dehumidifiers and humidifiers may be installed in the living room, but this comes with the issue of high electricity costs.
[0006] To provide a device for maintaining comfort in a room by providing a humidity control function to the air intake port of ventilation equipment that must be installed under the Building Standards Law, thereby controlling the humidity of ventilated intake air without requiring electricity charges apart from ventilation. [Means for solving the problem]
[0007] In the present invention, the intake air ▲1▼ passes through the ventilation opening ▲3▼, passes through the external grill ▲7▼, is exposed to silica gel ▲6▼ with an absorption / release formula spread on a multi-layered mesh ▲5▼ covered by a casing ▲4▼ and stretched on a crossbeam ▲8▼, and is then supplied through the interior decorative grill ▲2▼.
[0003] That is, when the intake air (1) is drawn in through the intake port (3), it comes into contact with silica gel (6) that is formulated to be able to absorb and release air and is laid on multiple layers of mesh (5), and is then supplied into the room. At this time, the intake air (1) is humidified by the silica gel (6) and supplied into the room. [Effects of the Invention]
[0009] The present invention can be applied not only to new construction but also to existing houses. [Brief explanation of the drawings]
[0004] [Figure 1] FIG. [Figure 2] FIG. 4 is a cross-sectional view of a second embodiment of the present invention. MODES FOR CARRYING OUT THE INVENTION
[0011] As shown in Figure 1, the intake air ▲1▼ passes through the ventilation opening ▲3▼, the external grill ▲7▼, and is exposed to the silica gel ▲6▼ with an absorption / release formula that is spread on top of multiple layers of mesh ▲5▼ that are covered by the casing ▲4▼ and stretched on the crossbeam ▲8▼, and then passes through the indoor decorative grill ▲2▼ and is supplied to the room.
[0012] The key point of the present invention is that outside air is supplied to the room without significantly impeding the amount of ventilation, as occurs with ordinary air intake filters.
[0005] The key point of the present invention is that silica gel (6) formulated to be able to absorb and release air is used, and that air can be supplied in a form with extremely little resistance to airflow. Example 1
[0014] In this example, silica gel (6) is formulated to have a humidity control function as well as a deodorizing function for formaldehyde odor, ammonia odor, acetic acid odor, etc., thereby controlling humidity and deodorizing odors in a room. Example 2
[0015] This is an embodiment of the present invention in which a fan (9) is provided at the ventilation opening (3) to supply air, and the invention is used for second-class ventilation.

Claims
[Claim 1] This ventilation and humidity control device controls the humidity of the intake air (1) ventilated from the ventilation opening (3), passing through the meshes of the external grill (7), and then exposing it to silica gel (6) with an absorption / release formula spread on a mesh (5) that is multiple times stacked and covered by a casing (4) and stretched on a crossbeam (8). The intake air (1) is then supplied into the room through the indoor decorative grill (2).
