DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer case for a hot air heater or the like.

[0002]

2. Description of the Related Art In an assembling operation of a warm air heater or the like, there is always an intermediate check operation, and it is customary to perform an operation according to a purpose in a state where an outer case is temporarily assembled. In particular, work with the front plate removed as shown in FIG. 6 is common. At this time, as shown in FIG.
The projections 16 and 18 are respectively engaged with cutouts 17 and 19 of the side plate.

[0003]

However, in the configuration shown in FIGS. 5 and 6, when the assembly line vibrates during operation or when a part of the operator's body touches the top plate, the top plate is moved. It was easier to come off and the work was very troublesome. Further, in order to prevent the top plate from coming off as shown in FIG. 7, extra work is required in the assembling work, such as screwing the top plate 15 and the side plate 14, and the screw head is conspicuous. There were issues such as a little loss of appearance.

[0004] Therefore, in order to solve the above-mentioned problems, an object of the present invention is to prevent the top plate from coming off from the side plate even in a temporarily assembled state without impairing the appearance.

[0005]

In order to achieve the above object, the outer case of the present invention has at least a plurality of projections at the joint of the top plate and the side plate, and fits the projections. A side plate is provided with a cutout portion as much as possible, and a part of the cutout is bent.

[0006]

[Function] The projection of the top plate and the notch of the side plate are fitted,
Further, a part thereof is bent and does not shift from each other.

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of an outer case according to an embodiment of the present invention.

FIGS. 1 and 2 show an embodiment of an outer case. In an exterior case of a household appliance such as a warm air heater, a side plate 2 and a front plate 4 are placed on a gantry 1, and a top plate 3 is joined to the side plate 2 and the front plate 4. Then, a device corresponding to the purpose of the appliance is housed in the outer case. As shown in the top view of FIG. 3, the side plate 2 is provided with a bent surface 9 at an upper portion, and has cutouts 5 and 7, and further, nail bent portions 6 and 8 are provided near the cutout. Is provided. The top plate 3 is finished with a synthetic resin or the like, and is provided with projections 10 and 11 to fit into the cutouts 5 and 7 of the side plate 2.

A procedure for assembling the outer case with the above configuration will be described. Although not shown, various devices are already installed on the gantry 1, and the side plates 2 are also mounted on the gantry 1 by screws or the like and joined. Next, the top plate 3 is
0 and 11 are inserted into the cuts 5 and 7 of the side plate 2 slightly obliquely upward so as not to hit the claw bent portions 6 and 8 of the side plate 2, and are slid sideways. At this time, the back surfaces B of the projections 10 and 11 of the top plate 3 abut against the claw bent portions 6 and 8 of the side plate 2, and the top plate 3 is sandwiched between the side plates 2. Thereafter, the claws 12 of the front plate 4 shown in FIG. 2 are joined to the top plate 2 while being inserted into the top plate 3 and fixed with screws 13 to complete the outer case assembly.

[0010] However, in order to secure the performance of the instrument and to maintain the safety, it is common to perform various tests with the front plate 4 removed. At this time, various actions (forces) are acting on the instrument due to vibration of the assembly line, movement of the hand of the worker, and the like. Above all, since a device (not shown) for operating the instrument and the like are mounted on the top board 3, a force is always applied. Even in such a case, in the present exterior case, the top plate 3 does not come off from the side plate 2 and does not need to be fixed by screws or the like, and is firmly held, contributing to the rationalization of assembly.

[0011]

As is apparent from the above description, according to the outer case according to the present invention, the outer case is always in a temporarily assembled state even when various tests which are indispensable to the process of assembling the device are confirmed. The present invention provides a strong exterior case that has good appearance and good appearance without screw tightening work.
