Description

[Detailed Description of the Invention] The present invention relates to a burner mounting structure in a water heater, and particularly to a wall-mounted instantaneous water heater, and is intended to facilitate the installation and removal of the burner.

Hereinafter, the present invention will be specifically explained based on illustrated examples.

1 is a main body of a water heater, and an operating section 2 is provided on the front surface of the main body 1, and an intake/exhaust top 3 is provided on one side of the main body 1 to communicate the inside of the main body with the outside of the main body.

Further, a heat exchanger 4 is disposed in the main body 1 from above, and a gas burner 5 for heating the heat exchanger 4 is disposed below the heat exchanger 4.

Reference numeral 6 denotes a front tube that is connected and fixed to the gas burner 5 via a metal fitting 16, and the front tube 6 is connected to a mechanical block 8 such as a solenoid valve that is fixed on a board 7 that is removably placed on the bottom of the main body 1. The mechanical block 8 is also controlled by a relay 9 fixed to the board 7.

Reference numeral 10 denotes a side plate that removably closes an opening 11 provided on one side of the main body 1 with screws or the like.

A set plate 12 is attached to the tip of the gas burner 5, and the set plate 12 is placed on a receiving plate 13 fixed to the rear inner wall of the main body 1.

Further, the mechanical block 8 and the relay 9 are arranged in a side U-shaped space defined by the burner 5, the front pipe 6, a fixing fitting to be described later, a board 7, etc.

14 is a fixture for connecting and fixing the front tube 6 and the base plate 7; 15;
is a heat shield plate installed horizontally between the burner 5 and the relay 9.

The present invention has the above-mentioned structure, and when attaching and detaching the burner for maintenance and inspection, the entire board 7 can be easily taken in and out from the opening 11.

Further, when only the relay 9 is to be taken out, it can be easily taken out through the opening 11 by separating the relay 9 from the substrate 7.

Conventionally, this type of wall-mounted water heater was usually installed at a relatively high position for operational reasons, and control components such as mechanical blocks and relays were concentrated in the lower part of the main body due to the need for maintenance and inspection. Because of the need to provide the necessary parts, the arrangement of each member is often complicated, making it extremely difficult to attach and detach each member or roughly each block. has become easier.

In other words, as is clear from the above, the present invention uses an arrangement structure in which the burner is placed leaving a space on the board that is the base of the internal parts, and parts that are frequently attached and detached, such as mechanical blocks and relays, are provided in this space. Not only can each part be attached and removed extremely easily, the space at the bottom of the device can be used effectively and neatly, but the device as a whole can also be made smaller, which has great practical effects. It is.
