Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board mounting device for a combustion appliance such as an oil fan heater.

[0002]

2. Description of the Related Art In combustion appliances such as oil fan heaters, generally, a blower fan, a blower for combustion, a fuel pump,
A board on which various elements for controlling temperature control and the like are mounted is mounted. Also, when something hits or an earthquake occurs,
Since a fire may occur if a burning appliance is shaken or fallen down greatly, a seismic shock absorber is attached, and when a seismic shock sensor detects an earthquake, the fire is extinguished immediately.

FIG. 8 is a transverse sectional view showing the structure of a conventional combustion instrument having such a function, and FIG. 9 is a longitudinal sectional view thereof.

In the figure, 1 is a bottom plate of a combustion appliance, 2 is a combustor arranged on one side of the bottom plate 1, and 3 is indoor air sucked from a suction port 4 at the rear of the apparatus and heated by the combustor 2. A blower fan that blows out warm air from the air outlet 5 at the front of the device, and 6 is an air passage wall that connects the air inlet 4 and the air outlet 5,
A blower fan 3 and a combustor 2 are arranged in a wind tunnel surrounded by an air passage wall 6. Reference numeral 7 is a main body case having the bottom plate 1 as a bottom wall, 8 is a cartridge tank storage portion provided on the bottom plate 1 on the side opposite to the combustor, and 9 is a tank outlet lid provided above the tank storage portion of the main body case 7. , 11 is a cartridge tank that can be taken in and out from the tank outlet, 12 is a guide plate for the cartridge tank 11, 13 is the cartridge tank 1.
An oil pan for receiving 1 below, 14 a substrate holding spacer provided so as to project from the front surface of the guide plate 12, and 15 a guide plate 12
Is vertically arranged along the front surface of the base plate and is attached to the guide plate 12 through the holding spacers 14, 16 is a heat shield plate for protecting the base plate 15 from heat on the side of the combustor 2, and 17 is a temperature inside the wind tunnel. This is a seal for preventing wind from leaking to the substrate 15 side. Further, although not shown in the drawing, a seismic sensor, which needs to ensure the levelness at the time of mounting, is mounted on the bottom plate 1 and is connected to the substrate 15 via a lead wire.

The conventional burner is constructed as described above, and the substrate 15 is composed of the air duct wall 6 and the heat shield plate 16 as the burner 2.
It is vertically arranged in a space isolated from the side, and a seismic sensor is further mounted on the bottom plate 1. It is needless to say that the substrate 15 is arranged in a space that is thermally isolated from the side of the combustor 2 because its installation position is right next to the wind tunnel and the environment is such that hot air easily leaks. In addition, the seismic sensor is the bottom plate 1
In addition to the fact that it is necessary to secure the levelness at the time of mounting as described above, the amount of swinging when a child hits the burning appliance is small at the bottom plate 1 because it is installed on the top. This is because the number of detections can be reduced and the accuracy of detecting an earthquake can be improved.

By the way, in addition to the above-mentioned examples of the conventional burner, there is one in which the substrate is horizontally arranged on the upper surface of the main body case. In this case, it is needless to say that the heat shield structure at the place where the substrate is installed needs to be solid because it is more easily affected by heat. Further, even in such a case, the seismic sensor is actually mounted on the bottom plate and connected to the substrate through the lead wire for the reason described above.

[0007]

As described above, in the conventional burner, since the substrate is placed in an environment that is easily affected by heat such as right next to the wind tunnel or the upper surface of the main body case, the shield is not provided. The thermal structure needs to be solid and is subject to design constraints.

Further, the seismic sensor cannot be directly attached to the board due to the arrangement position of the board, and it is necessary to connect the seismic devices to each other by the lead wires, so that the lead wires are not affected by heat. There was a problem that the work of pulling it around was troublesome.

In view of the above points, it is an object of the present invention to provide a board mounting device for a combustion appliance, which allows the board to be arranged at a site where the influence of heat is minimized and allows the seismic sensor to be directly mounted on the board. To do.

According to a first aspect of the present invention, there is provided a board mounting device for a burner, wherein a rail member for guiding and supporting both sides of the board in a horizontal state is provided on a bottom plate of the burner. .

Further, a board mounting device for a combustion appliance according to a second aspect of the present invention is one in which a vibration sensor is mounted on the board.

According to a third aspect of the present invention, there is provided a board mounting device for a combustion appliance, wherein the rail member is provided with a cover for covering the board.
