## Abstract

An object is to provide a water heater mounting structure for mounting a case to a mounting surface via a support fitting component that is fixed to the mounting surface in a vertical direction. The case houses a burning device. On a back plate of the case, a lock-engagement fitting component is mounted. The lock-engagement fitting component has an upper plate portion and a lower plate portion. The upper plate portion is fixed to the back plate, and the lower plate portion is lock-engageable with the support fitting component from thereabove and has a dimension longer than the support fitting component in the left-right direction. The lower plate portion is lock-engaged with the support fitting component from thereabove to hang and support the case through the lock-engagement fitting component by the support fitting component.

## Claims

### Claim 1

A water heater mounting structure for mounting a case in which a burning device is housed, to a mounting surface, via a support fitting component that is fixed to the mounting surface in a vertical direction and that has a lock-engaged portion facing upward, comprising:
a lock-engagement fitting component that is mounted to a back surface of the case and includes a fixed portion which is fixed to the back surface, and a lock-engaging portion that is joined to the fixed portion, is lock-engageable with the lock-engaged portion from above the lock-engaged portion, and has a dimension longer than that of the lock-engaged portion in a left-right direction;
wherein the lock-engaging portion is lock-engaged with the lock-engaged portion from above the lock-engaged portion to hang and support the case through the lock-engagement fitting component by the support fitting component; and
wherein the lock-engaging portion has, at a lower end, a turned-back portion that is turned back towards a front side of the lock-engaging portion and that extends substantially in an upward direction from the lower end so as to overlap the lock-engaging portion.

### Claim 2 (depends on 1)

The water heater mounting structure according to claim 1, wherein the lock-engaging portion is disposed over almost an entire length of a width of the back surface of the case in the left-right direction.

### Claim 3 (depends on 1)

The water heater mounting structure according to claim 1, wherein the lock-engaging portion has, at a lower end, a turned-back portion that extends in the left-right direction, and that comes into contact with the support fitting component in a state where the lock-engaging portion is lock-engaged with the lock-engaged portion.

### Claim 4 (depends on 3)

The water heater mounting structure according to claim 3, wherein the turned-back portion has an insertion portion in which a thickness in a front-rear direction is increased upward from a lower end so as to form an acute angle, and the insertion portion has a forward tilting front surface.

### Claim 5 (depends on 1)

The water heater mounting structure according to claim 1, wherein stoppers for preventing the lock-engaged portion from falling from the lock-engaging portion are disposed on both left and right sides of the lock-engaging portion.

### Claim 6 (depends on 1)

The water heater mounting structure according to claim 1, wherein the lock-engaged portion is plate-shaped.

### Claim 7 (depends on 1)

The water heater mounting structure according to claim 1, wherein
a mounting fitting component is fixed to the back surface above the lock-engagement fitting component, and the mounting fitting component has a provisionally attaching hole that is lock-engageable with a screw disposed at the mounting surface, and a fully attaching hole through which a screw is screwed into the mounting surface, and
the case is mountable to the mounting surface through the mounting fitting component in a state where the case is hung and supported by the support fitting component.

### Claim 8 (depends on 1)

The water heater mounting structure according to claim 1, wherein the support fitting component includes a fixed plate portion which is fixed to the mounting surface, a horizontal plate portion that is bent forward from an upper end of the fixed plate portion, and the lock-engaged portion that is bent upward from a front end of the horizontal plate portion.
