DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present embodiment shown in FIGS. 1 to 7 is mainly mounted on a wall 1 for partitioning the interior and exterior of a room such as a bathroom or a washroom, and the room is ventilated, dried, or heated. The present invention relates to an air blowing device. As shown in FIG. 1, the blower includes a ventilation unit 2 that can be called a ventilation blower that sucks indoor air and exhausts the air to the outside of the room, and a circulation unit 3 that can be called a hot air blower that raises the temperature while circulating indoor air. It is composed of

The ventilation unit 2 is provided in a metal-made cylindrical (or square-tube-shaped) wind tunnel 5 which can be inserted into a through hole 4 provided in a wall 1 of a bathroom or the like, from the indoor side to the outdoor side. (See FIGS. 1 and 2). The wind tunnel 5 is constituted by connecting an indoor side portion 7 and an outdoor side portion 8 so as to be extendable and contractable, and a blower 6 is mounted on the indoor side portion 7, and a rectangular mounting flange 9 which protrudes in a radial direction is provided on a front edge thereof. Is formed. The mounting flange 9 has an upward hook-shaped hooking structure 10 at its upper edge.
Are provided continuously, and the lower edge is provided with a fixing portion 11 which projects forward and has several screw holes at intervals. On the other hand, an open / close shutter 12 that opens and closes the wind tunnel 5 is attached to the rear end of the outdoor portion 8. The indoor side portion 7 and the outdoor side portion 8 are each provided with an elongated hole 13 and a tightening screw 14 in the center line direction.
Are connected by a slide structure as shown in FIG.
The length can be adjusted according to the wall thickness of the mounting portion.

As shown in FIGS. 1, 3 and 4, the circulation unit 3 is constructed by incorporating a circulation blower 16 and a far-infrared heater 17 as heating means in a box 15 having a heat-resistant structure. The box 15 has two open ends 1 on the front.
A series of air passages 20 facing the air passages 8 and 19 are defined, and the air passages 20 are provided with a circulating blower 16 for forming an airflow from the upper open end 18 to the lower open end 19. The far-infrared heater 17 is mounted near the open end 19 of the air passage 20 downstream of the circulation blower 16 so as to cross the air passage 20. On the rear side of the box body 15, there are provided air passage structures 22 that are open to the room through cutout windows 21 on both sides and are open on the rear side. An engaging member 23 that can be hooked on the hooking structure 10 of the ventilation unit 2 is provided on a rear upper portion of the box body 15, and a fixing edge 24 that can overlap the fixing portion 11 of the ventilation unit 2 from the outside is provided on a lower portion thereof. Each is provided. Several fixed holes 24 are formed in the fixed edge 24 in the lateral direction as shown in FIG.
One screw hole can be screwed.

In this blower, the wind tunnel 5 of the ventilation unit 2 is inserted into the through hole 4 formed in the wall 1 of the bathroom or the like with the opening / closing shutter 12 side inward, and the mounting flange 9 is brought into contact with the wall surface on the indoor side. And fix it with the mounting screws.
It is installed by attaching the circulation unit 3 to the front of the ventilation unit 2 so as to cover Regarding the electric system, by connecting the system on the ventilation unit 2 side to the system on the circulation unit 3 side, the circulation blower 16 and the far infrared heater 1 are connected.
7 and the blower 6 can be supplied with power, and the operation is controlled by a control circuit 27 provided on the circulation unit 3 side as a single blower (see FIG. 6).

When the circulation unit 3 is attached to the ventilation unit 2, if there is an obstacle such as a lighting fixture on the side wall surface of the installation location, the engagement position of the engagement member 23 with the hook structure 10 of the ventilation unit 2 is changed. Sliding in the horizontal direction can avoid interference with obstacles. Also, in the case where the circulating unit 3 is mounted on a corner wall surface of a bathroom or the like, the circulating unit 3 can be mounted away from the wall surface by the same operation.

When the installation space is set to a dry atmosphere, the blower 6 of the ventilation unit 2, the circulation blower 16 of the circulation unit 3, and the far-infrared heater 17 are operated. Thereby, the installation space can be circulated by the circulation unit 3 for warm air,
A dry atmosphere is obtained due to the removal of humidity by the ventilation by the ventilation unit 2. The intake of room air into the ventilation unit 2
This is performed by an air passage structure 22 that communicates with the cutout windows 21 on both sides of the circulation unit 3. Since both suction and discharge of the indoor air of the circulation unit 3 are performed on the front surface of the box 15, even if the air is installed near the ceiling, the suction performance does not decrease and the installation place is less restricted.

By operating only the circulation unit 3, the interior of the room can be heated. However, since the heating is performed by the radiant heat of the far-infrared heater 17 and the warm air, the feeling of the cool wind of blowing air to a person taking a bath is felt. And the feeling of use as a heating device is good. If only the ventilation unit 2 is operated, the air in the room can be exhausted and ventilated.

As described above, the blower can be installed using the through hole 4 of the wall 1 without any duct piping or the like, and can be easily installed in a new house or an existing house.
As the dry ventilator, the circulation unit 3 and the ventilation unit 2 may be formed integrally instead of being independent. However, by adopting the independent configuration, not only is it easy to handle and install, but also the circulation unit 3 can also be independently attached to a wall surface of a bathroom or the like using a fixing structure.

Even in an existing bathroom or the like where ventilation equipment such as a ventilation fan has already been provided and is functioning effectively, the existing ventilation equipment does not compete with the existing ventilation equipment, and the bathroom or the like does not have excessive ventilation. Drying and heating can be performed. In this sense, with the configuration including only the circulation unit 3, it is possible to provide a blower that can make the room a dry ventilation atmosphere or a heating atmosphere by using the ventilation unit in combination.

Further, by preparing a box having a simple ventilation function having a common fixing system to the ventilation unit 2, that is, a decorative grill 28 as shown in FIG. Instead of the circulation unit 3, a decorative grill 28 having a small appearance and a good appearance can be attached and used as a ventilation device exclusively for ventilation. By adopting such a configuration, the circulation unit 3 can be stored when it is unnecessary, and the aesthetic appearance and function of the circulation unit 3 can be maintained for a long time, so that the convenience is enhanced.
