Description

[Detailed description of the invention] [Industrial application field] This invention relates to a water heater that is installed horizontally using a hole in a wall in a high-rise apartment complex.

[Conventional technology]

Conventionally, this type of water heater has a structure in which all functional parts such as the combustion chamber, heat exchanger, and flasher are installed so that they protrude toward the indoor side, so the protrusion toward the indoor side is extremely large. This caused many problems in terms of the use of indoor space, as the interior space was significantly restricted. Therefore, as shown in Japanese Utility Model Application Publication No. 59-185551, a wall-penetrating water heater has been proposed, which is installed horizontally using a hole in the wall.

[Problem that the invention attempts to solve]

For the above-mentioned conventional wall-mounted water heater,
A horizontally rectangular cylindrical case is inserted from the side into a wall hole and fixed, all the interior parts of the water heater are mounted on a series of mounts, and the interior parts are made removable inside the case. The aim is to simplify the work during maintenance, inspection, repair, etc. of the enclosure, but when attaching and removing the interior contents to the enclosure, the pedestal is slid along a guide rail installed inside the enclosure. As a result, the structure of the pedestal and the structure for attaching interior items to the pedestal are complicated, and the assembly work is also troublesome.

This idea was made in view of the problems of the conventional technology, and its purpose was to simplify the structure by integrating the combustion chamber and the frame and eliminating the guide rail. The present invention aims to provide a water heater that realizes a reduction in the number of parts and simplification of assembly work.

[Means for solving the problem] In order to achieve the above object, the water heater of this invention has an outer cylinder equipped with an air supply port and an exhaust port that is inserted and fixed from the side into a mounting hole in the wall, and Combustion chamber, heat exchanger,
The internal structure consisting of functional parts such as the burner, the combustion chamber, a water supply pressure-responsive flasher installed on a base plate that extends out, an intake fan, and an electrical box can be removed from the outer cylinder and removed. A proximal opening is provided that allows for free insertion into the cylinder, and support legs with a predetermined height that match the inner width of the external part are hung on both sides of the bottom surface of the base plate of the internal structure and on both sides of the bottom surface of the combustion chamber. The supporting legs maintain a constant positional relationship of the internal structure with respect to the outer cylinder, and the partition plate provided on the inner circumferential wall at the tip of the outer cylinder has a partition provided on the outer periphery of the heat exchanger of the internal structure. The inside of the outer cylinder can be divided into an air supply side and an exhaust side by providing plates that can be moved toward and away from each other with a sealing material in between.

[Effect]

In the water heater of this invention with the above structure, functional parts such as a water supply pressure-responsive flasher and an intake fan are installed on the base plate that extends out integrally with the combustion chamber, so that the heat exchanger can be installed in the combustion chamber. , burners, and other functional parts are integrated. In addition, the internal structure can be freely inserted into and removed from the outer cylinder, and is positioned by support legs that match the inner width of the outer cylinder and have a predetermined height, so that their positional relationship is always maintained constant. Further, the partition plates provided on the outer cylinder and the internal structure abut each other with the sealing material in between to form a barrier, thereby dividing the inside of the outer cylinder into an air supply side and an exhaust side. The internal structure can be assembled and separated from the outer cylinder easily and reliably by simply putting the internal structure in and out of the outer cylinder, and most of the functional parts should be located in a portion corresponding to the wall thickness. As a result, the size of the protrusion toward the indoor side becomes extremely small, and the indoor space can be used effectively.

[Effect of idea]

As explained above, this idea involves inserting and fixing an outer cylinder from the side into a mounting hole in a wall, and keeping the internal structure in which each functional part is integrated inside the outer cylinder at a fixed relative position using support legs. When inserted from the proximal opening on the indoor side to a predetermined position, the partition plate comes into contact with the structure to create a shielding wall, so the internal structure is accurately positioned with respect to the outer cylinder by the support legs provided on the internal structure. The internal structure is inserted and held while maintaining a constant positional relationship, and as soon as the insertion of the internal structure into the outer cylinder is completed, the partition plates provided on the outer cylinder and the internal structure come into contact across the packing, and the inside of the outer cylinder is placed on the air supply side. Since there is no need for separate positioning or installation of a shielding wall, the assembly work can be simplified. In addition, the internal structure, which includes functional parts such as the heat exchanger burner, is compact because the functional parts such as the water supply pressure-responsive blinker and the intake fan are installed on the base plate that extends integrally with the combustion chamber. It can be integrated into the system, and its structure can be simplified.

However, due to the positioning of the internal structure relative to the outer cylinder using the supporting legs and the blocking of supply and exhaust air inside the outer cylinder using the partition plate, insertion and withdrawal of the internal structure from the outer cylinder may impair the function of the water heater. This can be done easily and reliably without any problems, and it is also possible to simplify the overall structure and reduce the number of parts.

Furthermore, since the internal structure can be inserted into and removed from the outer cylinder, it is convenient for maintenance, inspection, and repair, and most of the internal structure can be located in the area corresponding to the wall thickness, making it easier to use. Coupled with the compact body, the protrusion into the room is extremely small, making it particularly useful as a water heater installed in a hole in the wall of a high-rise apartment complex.
