Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall hanging device for a water heater.

[0002]

2. Description of the Related Art In a conventional water heater, when the water heater is installed on the outer wall of the water heater, as shown in FIG. 5, hot water is supplied by a fixing screw 23 through a hole 22 provided in a wall fitting 21 at the rear of the water heater. The machine 29 was fixed to the outer wall 30. In addition, when attaching a water heater to a wall such as a metal lath, the electrical equipment technical standard Article 182 requires wall construction so that the water heater 29 and the metal lath are not electrically connected.

Then, in such a case, as shown in FIGS. 6 and 7, an insulating plate 24 made of an insulating material is used.
Is inserted into the hole 22 of the wall fitting 21 at the rear of the water heater, and the wall fitting 21 is screwed with the insulating washer 25 made of an insulating material from the opposite side. It was installed so as not to be electrically connected to 30.

[0004]

However, in the above configuration, when the water heater 29 is installed on the outer wall 30, the insulating plate 2 is previously attached to the wall-mounting metal fitting 21 of the water heater 29.
4 and the insulating washer 25 are butted against each other from the opposite directions and are engaged with each other. It is necessary to install the water heater 29 by holding the water heater 29 at the installation position by hand and inserting the fixing screw 23. I couldn't install it. There is also a problem that the water heater 29 must be supported by hand until the installation position of the water heater 29 is determined.

The present invention is to solve the above-mentioned problems. It is not necessary to mate two parts, an insulating plate and an insulating washer, to a wall-mounting metal fitting, and they are electrically insulated by one part. The purpose is to carry out installation work smoothly without the need for support.

[0006]

In order to achieve the above object, a wall hanging device for a water heater according to the present invention has a locking hole in which an upper portion of a longitudinal elongated hole is cut out by a small elongated hole smaller than the elongated hole. It has a wall-mounting metal fitting for a water heater and a fixing screw to be screwed into the wall.It has a notch part that guides the fixing screw into the screw hole by notching the fixing screw through the lower part of the central screw hole on the upper surface. A wall surface contact portion that comes into contact with the wall surface, a pillar portion that protrudes from the center portion of the wall surface contact portion and has a shape that is substantially the same as the small elongated hole of the wall hanging bracket, and that stops the movement to the left and right, The front receiving part that further protrudes from the section, forms the longitudinal length of the long hole, covers the strut part, and forms a support groove at the upper part of the strut part for locking the small long hole of the wall hanging metal fitting to the wall hanging metal fitting. Insert the water heater into the outer wall through the wall bracket and the wall mount with the fixing screw. That.

[0007]

With the above structure, the wall support is first fixed to the wall surface with the fixing screw, and the locking hole of the wall mounting metal fitting of the water heater is passed through the wall support so that the locking hole comes into contact with the support groove. Lower. Therefore, even if the water heater tries to move forward from the wall surface, it can be stopped by the front support. Also, the movement to the left and right is stopped by the side surface of the locking hole hitting the side surface of the column. Therefore, the water heater can be easily installed while electrically insulating from the outer wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a wall hanging device for a water heater according to the present invention will be described below with reference to the drawings.

FIG. 1 shows a water heater, a wall fitting, a wall bracket, and a fixing screw showing an installation procedure on an outer wall according to an embodiment of the present invention. 2 is a plan view of the wall receiver, FIG. 3 is a side view of the wall receiver, and FIG. 4 is a cross-sectional view showing a state of installation on the outer wall.

In FIG. 1, there is provided a wall fitting 1 having a locking hole 13 formed by cutting out an upper portion of a longitudinal elongated hole 11 with a small elongated hole 12 smaller than the elongated hole 11 and a fixing screw 2 screwed into a wall 30. A wall surface contact portion 4 which is cut out in a fan shape below a central screw hole which penetrates the fixing screw 2 and is placed on the upper surface, and which has a notch portion 3 which guides the fixing screw 2 into the screw hole, and which abuts the wall surface 30, The pillar portion 5 protruding from the center portion of the wall surface contact portion 4 to support the small elongated hole 12 of the wall hanging metal fitting 1 with substantially the same shape, and to stop the movement to the left and right, and the pillar portion 5 further protruding from the pillar portion 5, The length in the vertical direction including the small elongated hole 12 has an outer diameter penetrating the elongated hole, and the support groove 7 is formed on the upper portion of the support pillar 5 to cover the support pillar 5 from the front. Water supply provided with a wall support 8 made of an electrically insulating material such as synthetic resin, which comprises the front support 6 9.

According to the above construction, 82 wall receivers are temporarily fixed to the wall 30 with the fixing screw 2 in advance so as to match the mounting pitch 1 of the locking holes 13 of the wall fitting 1 and then the water heater 9 Supporting hole to insert the locking hole 13 into the front receiving portion 6, and after inserting the water heater 9
If the support groove portion 7 abuts on the small elongated hole 12 of the wall-mounting metal fitting 1, the wall-mounting metal fitting 1 can be hung on the wall receiver 8. Then, the water heater 9 can be fixedly installed on the outer wall 30 by fully tightening the fixing screw 2 that is previously attached to the outer wall 30.

Even when the fixing screw 2 is retightened to prevent the water heater 9 from coming off the fixing screw 2, the wall support 8 does not rotate with the rotation of the fixing screw 2 and can be tightened smoothly. it can. The outer diameter of the thread portion of the fixing screw 2 is made smaller than the width of the notch portion 3 so that the deviation of the mounting pitch of the temporary fixing can be escaped. Of course, the width of the front receiving portion 6 may be slightly smaller than the short diameter of the elongated hole 11. Thus, even if the fixing screw 2 comes into contact with the lath net 14 or the like in the wall 30, the fixing screw 2
Can be electrically insulated by the wall support 8, and the water heater 9 and the wall 30 are not electrically connected.

[0013]

From the above description, in the wall hanging device of the water heater of the present invention, the wall support is first temporarily fixed to the wall surface with the fixing screw,
If the tool simply lowers the locking hole of the wall hanging metal fitting from the front receiving portion of the wall receiving member to the supporting portion, the movement to the front of the wall surface stops at the front receiving portion, and the movement to the left and right is also on the side surface of the column portion. If the side of the locking hole is abutted and stopped, and then the fixing screw is fully tightened, the fixing screw does not directly touch the wall hangings, so even if the fixing screw contacts metal such as lath net in the wall surface, By electrically insulating the receiver, the electrical connection between the water heater and the wall surface can be insulated.
