As described above, according to the present invention, the wind speed of the clean air discharged from the discharge port and blown is smaller than the wind speed of the contaminated air sucked from the suction port, so that the wind hitting the human body and noise are reduced. You can sleep easily. Also, because the dust collection filter is provided on the discharge port side, the dust collection filter acts as a resistance to reduce the wind speed of the clean air discharged from the discharge port and blown, and does not require large-scale equipment. Is.

Further, since the opening area of the discharge port is made larger than the opening area of the suction port, the air volume of the clean air discharged from the discharge port and blown is smaller than the air volume of the contaminated air sucked from the suction port. Therefore, the wind speed of the clean air discharged from the discharge port and blown can be reduced. In addition, the air purifier body is formed into a substantially U-shaped plane,
In addition to forming suction ports on both sides of the air purifier body and opening the discharge port inside the air purifier body between both suction ports, clean air is only available in the space surrounded by the air purifier body. The air purifier can be discharged and it is possible to make it more difficult for the contaminated air outside to be caught in the air purifier body.

Since the guide wall is provided around the discharge port and the tip of the guide wall is projected in the direction in which the clean air is discharged, the clean air discharged from the discharge port flows along the guide wall. The range of clean air can be expanded along the guide wall. Since vertical guide walls are provided as guide walls on both sides of the discharge port along the vertical direction of the main body of the air purifier, the clean air discharged from the discharge ports will flow along the vertical guide walls. The horizontal spread can be guided by a vertical guide wall.

Since a horizontal guide wall is provided above the discharge port as a guide wall along the lateral direction of the main body of the air cleaner,
The clean air discharged from the discharge port flows along the horizontal guide wall, and the horizontal spread of the clean air can be guided by the horizontal guide wall. Furthermore, the gap between the end portions on the tip side of the vertical guide wall is wider than the gap between the end portions on the air purifier body side so that the clean air discharged from the discharge port is vertical. As it flows along the guide wall, clean air can be spread radially.

Further, since the base portion of the guide wall is pivotally attached to the main body of the air purifier, the projecting angle can be arbitrarily set by rotating the guide wall. Further, since the guide wall is formed so as to be expandable and contractible in the front-rear direction of the air purifier body, the length of protrusion from the air purifier body can be arbitrarily set by expanding and contracting the guide wall.

Further, since the guide wall can be housed in the air purifier body, the guide wall can be housed in the air purifier body to make the air purifier compact when the air purifier is not used. In addition, since at least one of the suction port and the discharge port can be closed by the guide wall, it is possible to prevent dust from accumulating in the suction port and the discharge port.

Further, a plurality of vertical pieces are arranged side by side in the lateral direction to form a louver, and the louver is provided in the opening provided in the main body of the air purifier to form a discharge port between adjacent vertical pieces. A vertical piece located approximately in the center of the main body is provided in parallel with the front-back direction of the air purifier body, and the other vertical pieces are gradually inclined toward the vertical guide wall as they are positioned laterally of the air purifier body. Therefore, the clean air is discharged from the discharge port toward the vertical guide wall, and the clean air easily flows along the vertical guide wall.

Further, in this air purifier, a plurality of horizontal pieces are arranged in parallel in the vertical direction to form a louver, and the louver is provided in the opening provided in the main body of the air cleaner to discharge between adjacent horizontal pieces. As the outlet, the horizontal piece located at the top of the air purifier body was installed by inclining upward, and the other horizontal pieces were formed horizontally, so that clean air was discharged from the discharge port along the horizontal piece inclined upward. Therefore, the range of the clean air upward can be increased.

A means for forming a suction port in the upper part of the air purifier body and forming a discharge port in the lower part of the air purifier body for sucking polluted air from the suction port and discharging clean air from the discharge port. Is installed on the inner surface of the main body of the air purifier at the rear side of the suction port, so there is no need to provide a part for attaching a means for sucking polluted air from the suction port and discharging clean air from the discharge port. Thus, the depth of the air purifier can be reduced.

Further, the discharge port is formed in the air purifier body and the suction port is formed in the suction device, and the suction device is provided with means for discharging clean air from the discharge port to blow air. Since it is connected via a duct, it is possible to place the suction device equipped with a means for blowing clean air that generates noise away from the place where you sleep and to install only the quiet air purifier body near the place where you sleep. You can sleep without worrying about noise.

Further, a blower is formed by including an intake port and an exhaust port, sucking air from the intake port, exhausting air from the exhaust port and blowing air, and forming a blower. Since the air inlet and the air outlet are arranged opposite to each other, the air blower can reliably suck in the clean air discharged from the air purifier even if the installation interval between the air purifier and the air blower is increased. The space of the clean air formed at the installation interval between the fan and the blower can be enlarged.

Further, the air purifier is installed at the head-side end of the bed, and the suction portion provided with the suction port is provided so as to project from one side of the bed side surface of the air purifier and the discharge portion provided with the discharge port. On the other side of the bed side of the air purifier,
Since the suction port and the discharge port are opposed to each other, a space for clean air can be formed near the head of the bed.

Further, since the air purifier was installed at the head-side end of the bed and the suction port was opened in the direction opposite to the bed side and the discharge port was opened in the bed-side direction, cleaning was performed near the head of the bed. It is capable of forming an air space. In addition, the above-mentioned blower was installed at the foot side end of the bed, and the intake port of the blower and the discharge port of the air purifier were opposed to each other, so clean air formed at the installation interval between the air purifier and the blower. The space can be expanded from the head end to the foot end of the bed.

In addition, since the head part of the bed and the air purifier are covered with the hood, the clean air can be discharged only into the space surrounded by the hood, and the contaminated air outside the hood is less likely to be entrained. It is possible. Further, since casters are provided in both the air purifier and the air blower so as to be movable, the air purifier and the air blower can be moved to a desired place and used when necessary.
