[0007]

According to the present invention, there is provided a shutter snow melting apparatus provided with a shutter and a pair of left and right guide rails having a substantially U-shaped cross section in which the shutter is guided and both edges are bent inward. A device, wherein a hollow left and right side frame provided through a bottom wall of the left and right guide rails, and a hollow upper frame and a lower end which are connected to each other at the upper ends of the left and right side frames in a communicating manner. And a hollow lower frame connected in a communicating manner to form a warm air circulation passage, and a fan heater unit in which a heater for air heating and a blower are incorporated is arranged at a required position in the warm air circulation passage. Therefore, the air heated by the heater is forcibly circulated in the hot air circulation passage by the blower, and the heat of the hot air causes ice on the left and right side frames, the guide rails, the upper frame, and the lower frame surface. The snow is melted.

Further, since a plurality of slits for blowing hot air are provided at predetermined intervals in the bottom wall of each of the left and right guide rails having a substantially U-shaped cross section, the guide rails have the same shape .
The hot air blown from the hot air blowing slit along the inner surface of the edge melts the frozen snow on the surfaces of the guide rail and the shutter.

[0009] Moreover, the guide rails, the left and right side frames, because the material of the upper frame and Shitawaku is aluminum both, as compared with the steel thermal conductivity rather high, rapid freezing and snow <br / > be melt-.

The left and right frames are in contact with the vertical wall of the building.
With an L-shaped cross-section mounting wall,
Left and right side frames with mounting walls are each extruded with aluminum
The mounting wall is built with screws because it is integrally formed of
Build a shutter snow melting device simply by attaching it to the vertical surface of the structure
You can equip things .

Fan heater unit heater and the blower for air heating is incorporated (9) is arranged on a required position of the hot air circulation passage (8) in the bottom wall (3 left and right guide rails of the cross-section substantially U-shaped (2) ) a plurality of temperature air blowing Deyo slits (10) are spaced at a predetermined distance up and down respectively, the left and right guide rail
(2) and the left and right side frames (4) and (5) with the mounting wall (15)
Is it formed integrally with extruded luminium
The upper frame (6) and lower frame (7) are made of extruded aluminum
There is .

As shown in FIG. 2, in addition to the shutter (1) and the guide rail (2), the shutter device includes a shutter winding device (11) and a shutter case (12) for storing the wound shutter (1). ). The shutter (1) is formed by connecting a plurality of slats (13) up and down, and at each end of the slat (13), as shown in FIG. ) Are inserted alternately so as to be staggered on the left and right.

The mounting walls (15) of the left and right frames (4) and (5) are
By screwing to the vertical wall of (A) , the shutter snow melting device is attached to the wall of the building (A).

The hot air circulation passage (8) is formed by connecting the left and right frames (4) and (5), the upper frame (6) and the lower frame (7) as follows. That is, the upper frame (6) and the left and right frames
(4) and (5) are connected such that the rear side of the upper frame (6) is in contact with each front side of the left and right frames (4) and (5), and the lower frame (7) and the left and right frames (4) ( Five)
Are connected so that the left side of the lower frame (7) and the right side of the left frame (4) are in contact, and the right side of the lower frame (7) is in contact with the left side of the right frame (5). Each connecting portion is opened as shown in FIG. 3, so that warm air sent from the fan heater unit (9) can pass therethrough. The connection is performed, for example, by welding. The upper and lower ends of the left and right frames (4) and (5) and the left and right ends of the upper frame (6) are closed.
(5) Each upper surface and the upper surface of the upper frame (6), the left and right side frames (4) and (5) each lower surface and the lower surface of the lower frame (7), and the left surface of the upper frame (6) and the left side The left side surface of the frame (4), the right end surface of the upper frame (6), and the right side surface of the right frame (5) are flush with each other.

The fan heater unit (9) includes an upper frame (6)
It is attached to the center of the inside and connected to a power source (not shown). The blower blows air to the left. A timer is attached to the fan heater unit (9) so that the heater and the blower can be started at a designated time.

[0017] The hot air blowing Deyo slit (10) is a circle-shaped,
Almost two ratios are provided for three slats (13). Further, the hot air blowing slit (10) is provided in the forward portion of the bottom wall (3) so that the hot air to be blown easily hits the surface of the shutter (1).

In such a configuration, the frozen snow (S)
When melting, first, fan heater unit (9)
The heater inside generates heat, and the warmed air is sent to the left by a blower. Then, the warm air moves to the left inside the upper frame (6), passes through the connection opening between the upper frame (6) and the left frame (4),
Move down in the left frame (4). A portion of the hot air is blown out through the bottom wall (3) of the left guide rail (2).
After passing through (10), the shutter (1) is sprayed on the left side surface, and the rest passes through the connection opening between the left side frame (4) and the lower side frame (7), and moves rightward in the lower side frame (7) I do. Lower frame (7) and right frame
The warm air that reaches the opening of the connection with (5) moves upward in the right frame (5), and a part of the warm air blows out to the bottom wall (3) of the right guide rail (2). After passing through the slit (10), it is sprayed on the right surface of the shutter (1), and the remainder passes through the opening of the connection with the upper frame (6) and moves to the left. In this way,
The hot air is circulated in the circulation passage (8) and
From the slit (10) made in the bottom wall (3) of the drain (2)
It is blown out , and the left and right side frames (4) (5),
The frozen snow (S) on the surfaces of the upper frame (6), the lower frame (7), the guide rail (2) and the shutter (1) is melted.

[0019]

According to the shutter snow melting apparatus of the present invention,
Since icy snow heat by the frame surface and the shutter of the surface with the hot air is dissolved rapidly, or not open the shutter by icy snow, by trying to forcibly open the shutter icy snow deposited, a shutter Is not distorted, and the electric hoist type hoisting device does not break down.

The left and right side frames are in contact with the vertical wall of the building.
With an L-shaped cross-section mounting wall,
Left and right side frames with mounting walls are each extruded with aluminum
The mounting wall is built with screws because it is integrally formed of
Build a shutter snow melting device simply by attaching it to the vertical surface of the structure
You can easily equip things .
