んでいた。2. Description of the Related Art In general, this type of hot air heater is, for example,
As disclosed in Japanese Utility Model Publication No. 3-34596,
A wind tunnel containing a combustion tube is provided in an exterior case that has a warm air discharge port on the front side and a convection fan on the rear, and guides the wind of the convection fan to the hot air discharge port via the wind tunnel. ing. In addition, a heat shield plate that forms a cooling air path between the wind tunnel and the wind tunnel is installed inside the wind tunnel, and the wind tunnel is cooled by the cool air of the convection fan flowing through the cooling air path, so that the temperature rise at the top I try to suppress. Further, the wind tunnel is composed of a lower plate, a pair of left and right side plates and a wind tunnel top plate, and the heat shield plate is previously mounted on the lower surface side of the wind tunnel top plate via a plurality of support plates, and is used in a product assembly line. At the time of assembling the wind tunnel, the wind shield top plate with the heat shield plate attached thereto was attached to the upper portion of the both side plates and screwed, so that the heat shield plate was incorporated in the wind tunnel.

せる等の心配があった。In the hot air heater described above, since the heat shield plate is previously mounted on the lower surface of the wind tunnel top, the wind tunnel top is attached to the upper portions of both side plates. When performing the operation, the heat shield plate and the combustion cylinder are hidden by the wind tunnel top plate, making it difficult to confirm their positions. In many cases, the heat shield plate is forced to adhere to the wind tunnel top plate while it is in contact with the heat sink.In such a case, the rear part of the heat shield plate is deformed, which causes the heat shield plate to contact the convection fan. However, there is a concern that a contact sound may be generated.

One piece is sandwiched between the bent part of the side plate and the wind tunnel top plate.
Thus, the following effects can be obtained. The heat shield plate was assembled separately from the wind tunnel top plate
This makes it easy to check the positional relationship between the heat shield plate and the combustion cylinder.
To prevent deformation of the heat shield plate during assembly
it can. The downward locking piece provided on the upper part of the support plate is bent at the upper part of the side plate.
Engaging the engagement holes provided in the
Temporarily supported inside the fuselage, resulting in wind tunnel
The movement of the heat shield plate is reliably prevented when assembling the plate,
Workability of assembling the plate can be improved. The outward bent piece provided at the upper end of the support plate is bent to the side plate.
Since it is configured to be sandwiched between the part and the wind tunnel top plate, the support plate
To prevent the downward locking piece from coming off the engagement hole of the side plate.
And ensure that the heat shield plate does not fall
Can be specified.
