Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a configuration of an exterior case on which a combustion apparatus is mounted, such as a water heater, and more particularly to a housing that facilitates the attachment / detachment of a front front.
[0002]
[Prior art]
5 and 6 are side cross-sectional views showing the mounting structure of the front front 5 of the conventional outer case 1 of this type. When the front 5 is attached to the exterior case, in the configuration of FIG. 5, the upper part is inserted into the top 2 and the lower part is attached to the screw fixing part 7. In the configuration example of FIG. 6, the lower part is hooked on the claw of the base 3, and the upper part is fixed to the top surface 2 with screws.
[0003]
[Problems to be solved by the invention]
However, the above-described conventional casing configuration has the following problems. That is, in the case of the configuration example of FIG. 5, since the fuselage is in an installed state when the front is mounted, it is difficult to visually determine whether the screw hole position is small because the distance between the screw fixing portion and the floor surface is small. is there.
[0004]
In addition, there is a problem that it is difficult for the hand holding the screwdriver to touch the ground during screw tightening.
[0005]
Further, in the case of the configuration example of FIG. 6 in which the front screw fixing is provided on the upper side, since the method of inserting the front into the top cannot be adopted, the appearance of the appearance is deteriorated, and from between the front and the top. There was a problem that it was easy for rainwater to enter.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is designed such that when the front is mounted, when the upper part of the front is inserted into the top, the reinforcing metal fitting provided along the top is positioned for insertion into the upper part, and the surface having the lower screw fixing part is provided. An angle is provided obliquely upward with respect to the installation horizontal plane.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The housing of the present invention has a reinforcing metal fitting for positioning the upper insertion when the front front is inserted into the top. And since the surface of the screw fixing part at the lower part of the front is inclined diagonally upward with respect to the installation horizontal plane, the appearance of the top part is good and the top part covers the entire upper part. Invasion of rainwater and the like can be prevented. Further, the screw fixing portion at the lower front portion inevitably matches, and the screw fixing hole position is easy to check visually from above, and the front mounting workability is very easy to do.
[0008]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0009]
FIG. 1 is a partial side sectional view of a housing according to the present invention, FIG. 2 is a side sectional view showing a method of attaching to a front, FIG. 3 is a front view of the same, and FIG. 4 is a perspective view showing a method of assembling assembly parts. . 1 to 4, the casing is a box-shaped case 1, a top 2 having a side wall provided at the upper end of the case, a base 3 provided at the lower end, and a reinforcing metal fitting 4 provided on the inner surface of the top 2. The front 5 covers the front surface. When the front 5 is inserted into the inside of the side wall of the top 2, the reinforcing metal fitting 4 is fitted so that the front 5 and the top 2 have a certain distance and the outer side of the front 5 and the inner side of the top are fitted. Thus, the front 5 is positioned. In addition, the top having a side wall in the present embodiment may be a configuration that satisfies the requirement that the front can be inserted into the inner wall surface of the top. Therefore, a structure with a clear side wall such as a U-shaped cross section may be used, but even if the side wall is an unclear structure such as a U-shaped cross section or a V-shaped cross section, the above requirements are satisfied. It shall have a side wall, and the structure is not limited.
[0010]
The box-shaped front 5 has an exhaust port hole 6 in the upper part and a screw fixing part 7 attached to the base 3 in the lower part. Around this screw fixing portion 7, there is provided a surface having an angle α obliquely upward with a step-pushing 8 configuration with respect to the installation horizontal plane. Similarly, the base 3 is provided with a surface having an angle α that is in contact with the position of the front surface when the front is mounted so as to face the surface of the step push 8, and a screw hole mounting portion 9 is provided on the surface. Reference numeral 10 denotes a burner incorporated in the exterior structure as an embodiment of a hot water heater or the like, 11 is a heat exchanger, 12 is a muffler, and 13 is an exhaust port.
[0011]
Next, the operation and action will be described. When the front 5 is mounted, the upper part of the front is first inserted into the top. At this time, the reinforcing metal fitting 4 is used for positioning the front upper part.
[0012]
Next, when the lower part of the front 5 runs along the base 3, the screw fixing portion of the front 5 and the base 3 has an angle α with respect to the installation horizontal plane. , And the screw fixing portion 7 of the front 5 and the screw hole mounting portion 9 of the base 3 inevitably easily match. Furthermore, the screw fixing portion position can be easily confirmed visually even from above in the installed state, and the workability of mounting the front becomes very easy.
[0013]
【The invention's effect】
As described above, according to the housing according to the present invention, when the front is mounted on the exterior case, since the insertion to the top has the reinforcing bracket for positioning at the top, the screw fixing portion at the bottom of the front Since the stepped configuration is inclined obliquely upward with respect to the installation horizontal plane, the screw fixing part at the lower part of the front inevitably easily matches, and the position of the screw fixing hole can also be confirmed visually from above. This makes it easier and prevents the hand holding the screwdriver from touching the ground. Therefore, there is an effect that positioning of the front mounting and workability are easy to do.
[0014]
Furthermore, since the top can be drawn and the entire upper surface is covered, the design of the external appearance is good, and a waterproof structure against rainwater and the like in the body can be taken.
