Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a heater unit guard device for protecting a heater unit used in a tower kotatsu or the like.

[Technical background of the invention and its problems]

For example, in a kotatsu tower, a heater unit is attached to the inner ceiling of the tower, and this heater unit is covered with a guard. Conventional general guards are
A glass mesh plate is drawn to form a vessel-shaped main body, a guard frame is attached to the periphery of the opening of this main body, this guard frame is fitted to the outer periphery of the heater unit, and the guard frame is attached to the heater unit by screwing. ing. However, in such a guard, since the guard frame is provided on the main body, the structure is complicated, the material cost increases, and the guard frame is expensive.Also, the guard frame must be fitted to the outer periphery of the heater unit, so the heater unit The problem was that it was troublesome to install.

[Purpose of invention]

The present invention was developed with attention to these points, and its purpose is to provide a guard for a heater unit that is simple and inexpensive, and that can be easily attached to the heater unit. The goal is to provide equipment.

[Summary of the idea]

This invention involves aligning a large number of wires in parallel,
A slatted guard is constructed by connecting these wires with a plurality of reinforcing bones perpendicular to these wires, and a support plate is placed between the adjacent reinforcing bones from below, and the guard is attached to the heater unit. The guard is disposed opposite to the heat dissipation surface on the lower surface, and is attached to the heater unit by inserting a fastener such as a screw from the support plate to the attachment portion of the heater unit.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 indicates a wooden tower, which has legs 3 removably attached to the four corners of a ceiling body 2, and the ceiling body 2 is supported horizontally by these legs 3. The ceiling body 2 is constructed by assembling a plurality of inner bars 5 in a grid shape inside a rectangular outer frame 4, and the space in the center surrounded by each of the inner bars 5 is defined as a storage section 6. , the upper surface of this storage section 6 is closed by a top plate 7. The height dimensions of the outer frame 4 and each inner frame 5 are large, for example, 55 mm, in order to make the ceiling body 2 look like luxurious furniture.
It is formed to approximately the same size. Note that reinforcing bars 8, 8 are installed on the lower surface of the top plate 7.

A flat heater unit 10 is housed in the housing 6. As shown in FIG. This heater unit 10 is constructed by attaching a planar heater 12 to the inner bottom surface of a dish-shaped heat dissipation case 11, and horizontally attaches it to the lower surface of the top plate 7 via support fittings 13 attached to the side surface of the heat dissipation case 11. Supported. Support metal fittings 13
The lower end of the guard 15 protrudes below the lower surface of the heater unit 10, that is, the heat radiation surface 14, and is bent into an L shape to form a mounting portion 16 of the guard 15.

The guard 15 is constructed by aligning a large number of wires 17 in parallel and connecting these wires 17 with a plurality of reinforcing bones 18 perpendicular to these wires to form a slatted structure. Each wire 17... and each reinforcing bone 18
... are bent at right angles so as to face inward of the storage section 6, respectively. Support plates 19 are provided at each of the four corners of the guard 15, and each of the support plates 19 has bent pieces 21, 21 perpendicular to both ends of the main portion 20 in the shape of a strip, and each bent piece 21, 21. U-shaped engaging portions 22, 22 are integrally formed at the tips of the two. A circular insertion hole 23 is provided in the middle of the main portion 20, and elongated ventilation holes 24, 2 are provided on both sides of the insertion hole 23.
4 are perforated in each case. The support plate 19 formed in this way is connected to the adjacent wires 17, 17 and the reinforcing bone 1 from the lower surface side of the guard 15, respectively.
8, 18, the engaging parts 22, 22 are engaged with the reinforcing bones 18, 18, and this part is inserted into the reinforcing bones 18, 18 by spot welding, for example.
18, and thereby the support plate 19 is attached to the guard 15 in a state where it is constructed between the reinforcing bones 18, 18. The guard 15 is arranged so as to face the heat dissipation surface 14 of the heater unit 10 at a distance, and in this state, the screw 25 is inserted from the insertion hole 23 of the support plate 19 to the mounting part 16 of the heater unit 10, thereby The guard 15 is attached to the heater unit 10 so as to be flush with the lower opening of the storage section 6.

By energizing the planar heater 12, radiant heat is radiated into the tower 1 from the heat radiation surface 14 of the heater unit 10, and the inside of the tower 1 is heated. The support plate 19 faces the heat radiation surface 14, but this support plate 1
Since ventilation holes 24, 24 are formed in 9,
The radiant heat is effectively radiated into the tower 1.

The guard 15 includes wires 17 and reinforcing bones 18.
. . . and therefore can be manufactured inexpensively. Furthermore, when attaching this guard 15, it is only necessary to insert the screws 25 from the support plate 19 to the mounting portion 16 of the heater unit 10.
Since all that is required is to screw the fitting into place, the work can be carried out easily and efficiently.

In the above embodiment, the support plate 19 is inserted from the lower surface side of the guard 15 and the engaging portions 22, 22
Since the guard 15 is engaged with the reinforcing bones 18, 18, there is an advantage that the guard 15 will not come off even if the spot welding of the engaged portion is incomplete.

[Effect of idea]

As explained above, according to the present invention, the structure of the guard is simple and inexpensive, and the work of attaching the guard to the heater unit can be carried out easily and efficiently.
