Description

[Detailed Description of the Invention] The present invention relates to an electrical component mounting device for gas appliances.

Conventionally, in wall-mounted balanced-flue gas appliances with built-in gas burners and heat exchangers, an opening is provided only on one side of the left and right sides of the appliance body 1 for maintenance and inspection purposes, and the opening is closed with a lid. Covered by body 2.

However, this type of gas appliance requires two models, one that opens on the left side and one that opens on the right side, depending on the installation site, and for this reason, the mounting device for internal electrical components has to be changed to the left side opening type to match the two types mentioned above. Two specifications had to be prepared, one for the right side opening type, and it was inconvenient to store the parts and assemble them into the equipment.

The present invention is intended to eliminate such difficulties, and will be specifically explained below with reference to illustrations.

Figure 2 is an enlarged view of the main parts showing the state with the lid removed.
In the figure, 3 is an exterior casing, and 4 is a fixture fixed to the exterior casing 3, which in this embodiment has a U-shaped cross section.

Reference numeral 5 denotes a mounting bracket for attaching electrical components 6 such as relays and igniters, which has an L1-shaped cross section, and fastens the electrical components 6 to the mounting bracket 5 with a component tightening screw 7 that is tightened from one side of the device. It is.

Reference numeral 8 denotes a metal fitting screw that tightens the mounting metal fitting 5 to the fixing metal fitting 4 from a direction opposite to the direction in which the component tightening screw 7 is tightened.

9 is a heat exchanger with a water tube wound around it, and 10 is a gas burner.

The present invention has such a configuration, and an electrical component mounting device consisting of a mounting bracket 5 to which an electrical component 6 is attached in advance and a fixing bracket 4 is assembled into the instrument main body at the time of factory shipment.

Therefore, as shown in Fig. 3, when replacing the electrical components 6 such as the igniter necessary for igniting the gas burner in the left side opening type model, after removing the lid, loosen the component tightening screws 7. This allows the electrical component 6 to be taken out individually.

Also, as shown in Figure 4, in the model with an opening on the right side,
After removing the lid, the electrical component 6 can be taken out of the appliance together with the mounting bracket 5 by loosening the metal fitting screw 8, and can be replaced with a new part outside the appliance.

As described above, the present invention includes a mounting bracket that fastens electrical components,
It consists of a fixing bracket that is fixed to the exterior casing and tightens the mounting bracket, and the component tightening screws that tighten the electrical components are tightened in the same direction, and the bracket tightening screws that tighten the mounting bracket are tightened in the same direction. Since the direction is reversed, only one part is required regardless of the opening direction, and parts storage and parts replacement during maintenance and inspection are facilitated, which has a great practical effect.
