Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower device for blowing air to a dressing room such as a bathroom, and more particularly to a shape which senses the temperature of the blown air at the blower port and deforms according to the sensed temperature. The present invention relates to a blowing port device for a dressing room in which a variable body, for example, a so-called shape memory alloy or bimetal is installed in the blowing port, and the direction of air blown out from the blowing port is adjusted by the deformation operation of the shape variable body.

[0002]

2. Description of the Related Art Conventionally, automatic opening and closing of a vent according to room temperature is disclosed, for example, in Japanese Utility Model Laid-Open No. 4-14747. Further, in particular, Japanese Patent Application Laid-Open No. 9-79620 discloses a technique in which a plurality of wings (gulls) rotatably provided at a ventilation inlet of a bathroom are automatically opened and closed with a shape memory alloy operated by temperature. It is described in the gazette and known.

[0003]

In the conventional automatic opening / closing device for a vent described above, since the shape memory alloy senses and deforms the room temperature due to natural convection, the reaction operation of the shape memory alloy is slow. Depending on the direction of room air, there is a problem that the shape memory alloy hardly operates even though the temperature of the room changes. On the other hand, as shown in (a) and (b) of FIG. 1, when blowing warm air, the air is blown from the feet of the undresser, and when blowing cool air, It was common for the wind to hit the undressed upper body. For this reason, it was necessary to frequently change the direction of the gusset of the air outlet of a dressing room such as a bathroom. However, there is a problem that the undresser cannot easily and easily change the direction of the gull because the air outlet is usually located on the ceiling surface. If the undresser changes the direction of the gull with a hand controller (not shown), for example, to match the desired wind direction, the structure becomes complicated, and there is a problem that the device is easily broken.

[0004] The apparatus for blowing air to the undressing room of the present invention automatically changes the direction of the slurries to the undressing room in which the wind direction can be adjusted quickly and with high sensitivity between hot air blowing and cool air blowing. Is provided.

[0005]

In order to solve the above-mentioned problems, in the apparatus for blowing air to a dressing room according to the present invention, air is blown through a blowing duct to a blowing port installed in a dressing room such as a bathroom. A variable-shape body that senses the temperature of the wind, and that is deformed according to the sensed temperature is installed in the air outlet, and the direction of the wind from a grill or a gallery provided in the air outlet is adjusted by the deformation operation of the variable-shape body. With this configuration, it is possible to directly apply the wind blown from the air outlet to the shape deformable body, and the wind continuously hits the shape deformable body. Since heat is continuously supplied to the deformable body or heat is continuously removed from the deformable body, the heat deformation reaction of the deformable body is quickly and reliably performed.

It is preferable that the deformable body is a shape memory alloy. In this case, the deformable body stably maintains an open state of a grill or a gallery when blowing air.

Further, when a bimetal is employed as the deformable body, the opening state of the grill or the gull can be continuously adjusted.

In addition, a duct body is provided at an outlet of the blower duct, and a grill having a plurality of gulls is rotatably provided on the duct body. The variable shape member is provided between the duct body and the grill. When the grill is mounted so as to rotate with the change of the shape variable body, the entire grill is rotated, so that the inclinations of all the gulls can be controlled simultaneously.

In a case where the shape-variable body is substantially V-shaped and the rotation angle of the grill is adjusted by changing the angle between two sides forming the V-shape, the shape-variable body is Can be provided near the side wall of the air outlet, and the air blowing efficiency can be maintained satisfactorily.

A duct main body is provided at the outlet of the air duct, and a plurality of gulls are provided on the duct main body so as to be rotatable in parallel with each other. It is preferable that the lashes are connected by a lash connection component, and any one of the lashes and the duct body are connected by the above-mentioned deformable body. In such a case, the opening and closing operations of the guides are performed at the same time, and if any one of the gulls breaks down, it is possible to immediately know the failure.

In the case where the shape variable body is installed at the center of each of the parallel galleys in a state of being perpendicular to each of the parallel galleries, the blown air efficiently hits the shape variable body. Is reliably and quickly performed. Furthermore, if the deformable body is provided near one end in the longitudinal direction of the gallery, wind resistance due to the deformable body is reduced.

The grill 5 is not inclined with respect to the duct main body 7, and the side surfaces of each strip-shaped gallery 6 It is vertical. At this time, the opening angle α is determined according to the temperature of the hot air blown by the shape variable body 4, and as a result, the grill 5 is held in the illustrated state. When the air is blown in this state, the wind direction is directed directly downward as shown in FIG. 1A, and the warm air hits from the feet of the undresser. When the cool air is blown while the hot air is stopped, the deformable body 4 senses the temperature of the cool air and opens so that the opening angle α increases.

Further, since the variable shape member 4 is made of a shape memory alloy, the variable shape member 4 stably maintains the open state of the grill or gallery when blowing air. However, the deformable body 4 may be formed of a so-called bimetal, and the grill 5 or the gull may be rotated by utilizing the thermal deformation of the bimetal.
