Description

The present invention relates to a blower whose installation orientation can be changed.

BACKGROUND ART Devices with an air blowing function, such as futon dryers, are generally installed on the floor or the like while maintaining a certain posture with the bottom as the installation surface. Such devices usually have a support part such as a leg part on the bottom surface to stably support the main body. On the other hand, there are devices that can be installed not only in the normal posture but also in a posture different from the normal posture.

For example, the futon dryer disclosed in Patent Document 1 not only has legs on the bottom surface in a normal installation position, but also has legs on one side surface. Thereby, the installation posture can be changed so that the side surface becomes the installation surface.

Japanese Patent Application Publication No. 2018-79236 (published on May 24, 2018)

In the futon dryer disclosed in Patent Document 1, the hose is pulled out to the side of the main body for use, so the outlet of the fan is oriented to the side. Therefore, in order to store the hose inside the main body when the futon dryer is not in use, it is necessary to bend the hose upward.

However, since the bending radius of the hose is large, a large space is required in the air blowing direction of the fan in order to accommodate the bent portion of the hose within the main body. Therefore, in the normal installation position, the main body has a horizontally elongated shape. For this reason, if the main body is used in a 90° horizontally installed position, it will be installed in a vertically long position, resulting in poor stability.

To solve this problem, we can make the main body larger in the vertical direction in the normal installation position, and make the length of the installation surface in the overturned installation position closer to the installation surface in the normal installation position. Make the body closer to a square. Thereby, stability in an overturned installation position can be improved.

However, if the main body is formed to be large in the vertical direction in a normal installation position, the main body becomes large. For this reason, there arises an inconvenience that it becomes difficult to rotate the main body in order to change the installation orientation of the futon dryer.

An object of one aspect of the present invention is to improve stability in an overturned installation position and to realize a small-sized blower.

In order to solve the above problems, an air blower according to one aspect of the present invention includes a blower fan that blows air to the side, and a blower that is disposed on the side of the blower fan and that blows the air upward from the blower fan. a bendable hose that guides the air sent out from the air duct, a nozzle connected to the tip of the hose, and a housing containing the air fan, the air duct, and the hose; a lid that closes an opening formed at an upper end of the housing in a stored state in which the hose and the nozzle are stored in the housing, and the hose is provided so as to be drawn out from the housing; The nozzle has an outlet for blowing out air, and the lid is connected to the nozzle while being formed in a shape extending in a first direction that is the connection direction of the hose and the nozzle in the stored state, In the stored state, the hose extends from the other end of the housing in the first direction toward one end , and the air outlet of the nozzle extends toward the one end of the housing in the first direction. It is open towards.

According to one aspect of the present invention, it is possible to improve stability in an overturned installation posture and to realize a small-sized blower.

As shown in FIG. 2, the first support portion 5 is provided on the bottom surface 21. As shown in FIG. A second support portion 6 is provided on the back surface 23. When the bottom surface 21 is used as a surface (installation surface) for installing the futon dryer 1 on the floor F, the first support portion 5 stabilizes the futon dryer 1 on the installation target surface on which the futon dryer 1 is installed. This is the part for installing. The second support part 6 is a part for stably installing the futon dryer 1 on the installation target surface when the back surface 23 is used as the installation surface.

The first support portion 5 and the second support portion 6 are formed, for example, in a flat plate shape, but the shape is not limited to the flat plate shape. The first support part 5 and the second support part 6 may be formed into a rib shape or may be formed into a plurality of leg-like parts.

Although not shown, a handle section configured similarly to the handle section 241 is also provided on the side surface 25 at a position facing the handle section 241.

As shown in FIG. 3, the futon dryer 1 includes a blower fan 10, a casing 11, a heater 12, a blower duct 13, a hose 14, and a nozzle 15. The housing 2 incorporates these.

The blower fan 10 is arranged inside the housing 2 and generates an air flow by sucking in air from an air intake port (not shown) provided on a side surface 25 of the housing 2 and discharging it. . The casing 11 is an exterior body that covers the blower fan 10, and has an inlet (not shown) for sucking in air and an outlet 111 for blowing out air.

The heater 12 is arranged so as to be in contact with the outlet 111 in order to warm the air sent from the blower fan 10 through the outlet 111 of the casing 11 .

The air duct 13 forms an air path directed upward from the heater 12 so as to guide the air that has passed through the heater 12 toward the opening 20 (upward in the normal installation position shown in FIG. 3). The back surface 23 is arranged at a position close to the ventilation duct 13.

The hose 14 is formed in a cylindrical shape and forms an air path for guiding air passing through the blower duct 13. One end of the hose 14 is connected to an air outlet of the ventilation duct 13. Further, the hose 14 is formed, for example, in a bellows structure so that it can be expanded and contracted. Due to this structure, the hose 14 is stored in the housing 2 in a short contracted state in the stored state shown in FIG. 3, and is extended from the inside of the housing 2 to the outside in the operating state. (For example, see FIG. 4).

The nozzle 15 is a member that blows out air sent out from inside the hose 14. The nozzle 15 is connected to the tip of the hose 14 that serves as an air outlet, and has a wide flat outlet. With such a structure, the nozzle 15 can increase the flow rate of the air it blows out and blow the air out over a wide fan-shaped area. Further, the nozzle 15 is connected to the inner surface of the lid 3.

The lid 3 is a member that closes the opening 20 of the housing 2, and is formed in a shape that extends in the direction in which the hose 14 and the nozzle 15 are connected in the stored state . The lid 3 has a rectangular shape and has a flat top surface. Further, the lid 3 is configured to be integrated with the nozzle 15 connected as described above. Thereby, the lid 3 is connected to the housing 2 via the hose 14 and the air duct 13.

The operating state of the futon dryer 1 configured as described above will be explained. FIG. 4 is a side view showing how the futon dryer 1 is used. FIG. 5 is a side view showing another usage state of the futon dryer 1.

As shown in FIG. 4, for example, when drying the futon on the bed 101, the futon dryer 1 is installed in the normal installation position with the bottom surface 21 facing the floor F, which is the installation target surface. Install it on floor F and operate it. In this case, since the bottom surface 21 becomes the installation surface, the futon dryer 1 is supported on the floor F by the first support section 5. Also, open the lid 3, pull out the hose 14 from the back 23 side of the opening 20 of the housing 2, extend it above the bed 101, and connect the nozzle 15 together with the lid 3 so that the outlet of the nozzle 15 faces the area to be dried. It is placed on the bed 101.

In this state, the lid 3 functions as a stand for the nozzle 15. Furthermore, since the top surface of the lid 3 is planar, the nozzle 15 can be stably supported on the bed 101 by contacting the top surface with the bed 101. As a result, air is blown out from the nozzle 15 in a uniform direction, so that the inconvenience of uneven drying due to the nozzle 15 being tilted can be suppressed.

On the other hand, as shown in FIG. 5, for example, when drying the mattress 102 on the floor F and the comforter (not shown) covering it, the futon dryer 1 is installed with the back side 23 facing the floor F. The futon dryer 1 is installed and operated on the floor F in the installation posture. In this case, since the back surface 23 is the installation surface, the futon dryer 1 is supported on the floor F by the second support section 6.

In addition, the lid 3 is opened, the hose 14 is pulled out from the housing 2 and extended over the mattress 102, and the nozzle 15 is placed on the mattress 102 together with the lid 3 so that the outlet of the nozzle 15 faces the area to be dried. Even in this state, the lid 3 functions as a stand for the nozzle 15, so air is blown out from the nozzle 15 in a uniform direction.

In this manner, in the overturned installation position, air can be blown onto the drying object located at a low position with respect to the floor F by simply bending the hose 14 slightly. Therefore, a decrease in air blowing efficiency due to large bending of the hose 14 can be suppressed, and drying can be performed more efficiently.

When changing from the normal installation position shown in FIG. 4 to the overturned installation position shown in FIG. 5, the user rotates the futon dryer 1 from the normal installation position to the back side 23 and tilts it down. At this time, the user places his or her finger on the first finger hook 241a of the handle 241 shown in FIG. 4 from above to tilt the futon dryer 1 toward the back side 23. Further, when returning the duvet dryer 1 from the overturned installation position to the normal installation position, the user hooks his or her finger onto the second finger hook 241b of the handle 241 from above to pull up the futon dryer 1. In this way, since the handle portion 241 has the first finger rest portion 241a and the second finger rest portion 241b on which fingers are hung in different directions, the installation posture of the futon dryer 1 can be easily changed.

Further, since the second corner portion 27 is formed in a curved shape, when changing the installation posture of the futon dryer 1, the futon dryer 1 can be rotated as if rolling. Furthermore, the first support portion 5 is provided only on the bottom surface 21, and the second support portion 6 is provided only on the back surface 23. As a result, the first support part 5 and the second support part 6 do not extend to the second corner part 27, and the operation of rolling and rotating the futon dryer 1 is not hindered.

Further, the blower duct 13 is configured to guide the air sent to the sides of the blower fan 10 upward. Thereby, the width of the housing 2 in the air sending direction of the blower fan 10 can be reduced. Moreover, when the hose 14 is built into the housing 2, if the length of the air duct 13 is set appropriately, even if the hose 14 with a large bending radius is bent at the end of the air duct 13, the height of the housing 2 can be maintained. It is possible to suppress the Thereby, the height of the housing 2 (the distance between the bottom surface 21 and the top surface of the lid 3) can be made closer to the width (the distance between the front surface 22 and the back surface 23).

Therefore, the side shape of the futon dryer 1 (the shape of the side surface constituted by the side surface 24 and the side surface of the lid 3) can be brought closer to the positive direction, and the housing 2 can be made smaller. Therefore, even a weak user can easily roll the futon dryer 1 to change its installation position.
