Description

[Detailed Description of the Invention] The present invention relates to an operating section in a combustion appliance such as a gas water heater.

Conventionally, as shown in FIG. 1, a heat exchanger 2 is provided in an exterior casing 1 of a combustion appliance, and an internal pipe 3 leading to the heat exchanger 2 and an external pipe 5 passing through an upper plate 4 are connected by a connecting fitting 6. In the case of internally connected devices, the finished product cannot be inspected until after the operating panel 7 and controller 8 are assembled into the device, which has the disadvantage that leaks due to poor connection of the piping cannot be detected from the outside.

Furthermore, as described in Japanese Patent Application Laid-Open No. 49-5494, in which the control box is simply removed from the storage section and can be controlled remotely, it is possible to inspect the finished product, but the control box must be placed and supported for inspection. Not only does this require a stand, etc., making the work difficult, but no consideration was given to protecting the electrical components from water droplets after assembly was completed.

The present invention aims to eliminate such difficulties, make leakage inspection reliable and easy, and protect the controller section.

Hereinafter, this will be explained in detail based on an example. 9 is an exterior casing of the combustion appliance, 10 is a heat exchanger, 11 is a water supply pipe connected to the heat exchanger 10, an internal pipe consisting of a hot water supply pipe, 1
Reference numeral 2 denotes an external pipe that passes through the upper plate of the exterior casing 9, and is connected to the internal pipe 11 inside the instrument via a connecting fitting 14.

15 is a burner, 16 is a controller that controls opening and closing of a gas passage leading to the burner 15, and 17 is an operation plate located directly above the controller 16.

Reference numeral 18 denotes an electric wire cord that connects the operation panel 17, which is an operation section, and the controller 16.

Reference numeral 19 denotes a supporting metal fitting having a rectangular cross section fixed to the outer front surface of the controller 16, and reference numeral 20 denotes a hanging plate fixed to the back surface of the operation panel 17, which covers electrical components 21 such as switches.

Reference numeral 22 denotes a holding plate that holds the operation plate 17 in the vertical direction when the hook plate 20 of the operation plate 17 is hooked to the support fitting 19 of the controller 16.

The present invention has such a configuration, and although the state shown in FIG. 2 is a completed assembled product, in this state it is not possible to check from the outside whether there is shallow water coming from the connection fitting 14.

Therefore, as shown in Fig. 3, the operation panel 17 is
is latched onto the support fitting 19 of the controller 16 by the latching plate 20.

After that, gas, water, etc. are connected to simple piping to inspect the combustion state and the presence of shallow water.In particular, the internal pipe 11 and the external pipe 12
The shallow water condition from the connection fitting 14 can be easily checked through the mounting opening a of the operation plate 17.

By attaching the holding plate 22 to the lower part of the back surface of the operation plate 17, it becomes easy to open and close the switches without shaking the operation plate 17.

After the inspection is completed, the operation plate 17 may be fixed at the normal position as shown in FIG.

After installation and fixation, the hanging plate 20 covers the electrical parts 21 such as switches and circuit boards, and the holding plate 22 covers the upper part of the controller 16, so that the electrical parts can be protected from condensed water generated on the inner surface of the exterior casing 9. .

As described above, the present invention attaches a latching plate to the back of the operation panel, and after installation, attaches a holding plate that covers the controller, and attaches a support fitting on which the latching plate is placed to the outer front part of the controller, and then operates the Since the board is detachable from the controller, it is not only easy and reliable to check for leaks during inspections, but also protects electrical components such as the controller from water droplets after assembly is completed, eliminating the risk of electrical leakage and making it safer. It has the effect of improving sexual performance.
