Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a connection device for wall-mounted appliances such as instantaneous water heaters and fan convectors.

(Prior Art) As a conventional device of this type, one is known in which a connecting pipe protruding from the side surface of the instrument body and a main pipe provided on the wall are connected by a rubber tube or the like.

(Problems to be solved by the invention) However, according to the above-mentioned conventional device, connection work between the connecting pipe and the main pipe is required, which is time-consuming and undesirable. It is visually undesirable.

Therefore, in order to solve the above-mentioned inconvenience, it may be possible to attach quick joints to the tips of both tubes and connect both tubes directly on the back side of the device body, but according to this method, the connection work of both tubes is similar in external shape. The main body of the device is relatively heavy due to its large size and built-in heat exchanger, etc.
When lifted from the front side, the connecting pipe on the back side, which is difficult to see, is moved to the point where it matches the main pipe on the wall, and both pipes are connected with a quick joint. Since this is done by registering, it is difficult to align the centers of the quick joints of the two pipes, which increases the work time, and the weight of the instrument body may be directly applied to the two pipes during the connection work. This is not preferable as there is a risk of damaging these.

(Means for solving the problem) The present invention not only simplifies the connection work between the connecting pipe of the main body of the device and the main pipe of the wall surface, but also prevents excessive force from being applied to the two pipes during the connection work. A connection device for a wall-mounted appliance that connects a connecting pipe provided on the appliance body and a main pipe provided on the wall surface on the back side of the appliance body, wherein the connecting pipe protrudes rearward from the back of the instrument main body, with the connection port at its tip facing downward, and the source tube is provided with the connection port at its tip facing upward; A wall mounting member is provided on the wall surface, and an instrument mounting member is provided on the wall surface so that the wall mounting member can be attached and detached by sliding vertically in a positional relationship such that the connecting pipe is inserted into and removed from the main pipe. .

(Example) Next, a description will be given based on an illustrated example in which the present invention is applied to an instantaneous water heater.

In FIGS. 1 to 4, reference numeral 1 denotes a device main body equipped with a heat exchanger and a burner inside, and a connecting pipe 2 for water supply connected to a water pipe on the upstream side of the heat exchanger is provided on the back of the device main body 1. A connecting pipe 3 for tapping hot water connected to a hot water pipe on the downstream side of the heat exchanger, and a connecting pipe 4 for supplying fuel connected to the burner were provided to protrude rearward. In this case, the connection ports at the tips of each of the connection pipes 2, 3, and 4 were directed downward, and conventionally known quick joints were attached to these, although not shown.

A pair of substantially S-shaped wall mounting brackets 5, 5, 6, and 6 are further provided on the upper and lower sides of the back surface of the instrument body 1.

Further, 7 indicates a wall surface in which a recess 8 is formed, and a main pipe 9 for water supply, a main pipe 10 for hot water supply, and a main pipe 11 for fuel supply are connected to the lower surface of the recess 8 through connection ports at the tips. are provided so as to protrude upward, and a conventionally known quick coupling (not shown) is attached to these.

Further, reference numeral 12 denotes an instrument mounting bracket having an insertion port 13 into which the connecting tubes 2, 3, and 4 are inserted, and the insertion port 13 is formed into a cylindrical shape and is fitted into the recess 8 of the wall surface 7. The positioning is performed when attaching to the wall surface 7 with screws.

The appliance mounting bracket 12 was further provided with a pair of notches 14, 14, 15, 15 into which the wall mounting brackets 5, 5, 6, 6 were inserted at the top and bottom.

(Function) When attaching the device body 1 to the wall surface 7, first attach the device body 1 to the wall surface 7.
With the instrument main body 1 lifted up on the instrument mounting bracket 12 attached to the device, place the instrument body 1 facing each other as shown in FIG. The metal fittings 5, 5 are positioned above the pair of notches 14, 14 on the upper part of the appliance mounting metal fitting 12, and the pair of wall mounting metal fittings 6, 6 on the lower part of the back are positioned above the pair of notches 14, 14 on the upper part of the appliance mounting metal fitting 12. Notch 15,1
5, and connect the connecting pipes 2, 3,
Connect each connection port of 4 to the main pipe 9, 1 in the recess 8 of the wall surface 7.
0 and 11, and then the instrument main body 1 is lowered using the instrument mounting bracket 12 as a guide. In this case, as shown in FIG. 4, the pair of wall mounting brackets 6, 6 at the lower part of the back are locked to the bent part at the lower part of the instrument mounting bracket 12 to prevent the instrument body 1 from falling, and the upper part of the back A pair of wall mounting fittings 5, 5 are engaged with the upper flat portion of the instrument mounting fitting 12 to prevent the instrument main body 1 from falling forward, and the instrument main body 1 is fixed. Here, connecting pipe 2,
3 and 4 and the main pipes 9, 10, and 11 are automatically connected to each other by quick joints when the device body 1 is fixed to the wall surface 7 via the device mounting bracket 12. Therefore, the connection work of both pipes located in a hard-to-see place on the back side of the instrument main body 1 can be performed extremely easily and without applying excessive force to both pipes.

In addition, when a heat exchanger and a burner for heating the heat exchanger are provided in the appliance main body 1 as in the above embodiment, the water is sent to the heat exchanger through the main water supply pipe 9 and the connecting pipe 2. Water is heated by the burner, becomes hot water, and passes through the hot water connection pipe 3 to the main pipe 10 for hot water supply.
The desired hot water will be supplied to the outside.

FIG. 5 shows another embodiment, in which
The main pipes 9, 10, 11 provided on the wall surface 7 are provided so as to protrude forward, and the connection ports at the tips of the respective main pipes 9, 10, 11 are directed upward.
The structure is not particularly different from that of the embodiment shown in FIGS. 1 to 4 above, except that the insertion ports 13 of the connecting tubes 2, 3, and 4 provided in the connecting tubes 2, 2, and 4 are formed of through holes.

(Effect of the invention) As described above, according to the present invention, the connecting pipe is made to protrude rearward from the back of the instrument main body, and the connecting port at the tip thereof is provided facing downward, and the main pipe is connected to the connecting tube at the tip. Provided with the mouth facing upward, and
A wall mounting member is provided on the back side of the instrument body, and an instrument mounting member is provided on the wall surface so that the wall mounting member can be attached and detached by sliding vertically in a positional relationship such that the connecting pipe is inserted into and removed from the main pipe. By simply sliding the wall mounting member downward, the main body of the instrument can be attached to the wall and the connecting pipe and the main pipe can be connected. This is advantageous in that it is easier to work than the conventional method in which the pipes are attached to the pipes, and there is no need to apply unreasonable force to the pipes during the work.

In addition, since the connecting portions of both tubes are not visible from the front of the instrument body, the appearance is clean.
