DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for storing a check sheet for maintenance in a heating device such as a cooker, a heater or a water heater having a heat source composed of a gas burner.

[0002]

2. Description of the Related Art A maintenance check sheet is a sheet on which check items for failure diagnosis and check items for disassembly are described in order to help a service person perform maintenance. Conventionally, a check sheet is packed in a bag and affixed to the inside of the container because of the possibility of loss. And, in the heating equipment, there is a problem of temperature, so that non-combustible paper is used as a check sheet.

[0003]

The use of non-combustible paper as described above has a disadvantage that the cost is high, and the check sheet is stored in a relatively low temperature place in the housing so that plain paper can be used. It is desirable to be able to do so. An object of the present invention is to provide a storage structure for a check sheet in a heating device that meets such a demand.

[0004]

Means for Solving the Problems In order to solve the above problems,
The present invention relates to a heating device having a heat source composed of a gas burner , in which a substrate case for holding a circuit board is mounted in a housing, wherein the substrate case is connected to an air vent of the heating device.
The primary air flowing from the inlet to the gas burner mixing pipe
It is characterized in that it is attached to a location that will be a flow path, and that a pocket portion that can store a maintenance check sheet is provided in the substrate case.

[0005] Since the circuit board is vulnerable to heat, a board case is attached to a relatively cool place in the body , that is, a place cooled by primary air, to prevent heat damage to the circuit board. Therefore, the check sheet stored in the pocket portion of the board case is also maintained at a relatively low temperature. Even if plain paper is used as the check sheet, there is no problem and the cost can be reduced.

In addition, inspection of a circuit board is an important item in maintenance, and storing a check sheet in a pocket portion of a board case is rational in terms of maintenance.

If the pocket portion is formed by a gap between the circuit board and the circuit board in the board case, it is not necessary to form a special pocket portion in the board case.

In this case, the pocket portion is defined by the side plate of the board case and the side surface of the circuit board opposed to the side plate with a gap therebetween.
That is, a side plate portion may be formed on the circuit board so as to be opposed to the side surface with a gap for a pocket portion. According to this, the pocket portion defined by the side plate portion is provided in the substrate case. Further, even when the board case is omitted, the same operation and effect as described above can be obtained by providing the pocket portion for the check sheet on the circuit board.

And a grill burner 4 are provided. At the rear end of the top plate 2, an exhaust port 5 facing a grill exhaust duct 5 a is provided.
Has been established. 5b is an exhaust port cover in the figure.

An oven is placed under the stove,
Since the right side of the oven is a control box, the right side of the stove receives little heat from the oven. Therefore, a board case 7 for holding a burner control circuit board 6 is attached to the right side of the stove body 1. In addition, the mixing tube 4 a of the grill burner 4 is disposed behind the place where the substrate case 7 is mounted. Thus, the mounting place of the substrate case 7 is a flow path of the primary air flowing from the air intake hole 8 on the lower right side of the front surface of the body 1 to the mixing pipe 4a of the grill burner 4, and further, the stove burner 3 on the right side. ₁ mixing tube 3
The primary air sucked by a and the air sucked toward the exhaust port 5 by the draft effect by the exhaust flow from the exhaust duct 5a also flow through the mounting location of the substrate case 7. Therefore, the substrate case 7 is maintained at a relatively low temperature (about 70 ° C. or lower).

As shown in FIGS. 2 to 4, the board case 7 includes an upper edge of an upright portion 70 facing the right side plate 1 a of the body 1.
The upper plate 71, the lower plate 72, the front plate 73, and the rear plate 74 are formed by bending rightward to the lower edge, the front edge, and the rear edge, respectively. The cut-and-raised claw 72a is engaged with the hole 1c formed in the bottom plate 1b of the body 1, and the cut-and-raised tongue piece 70a formed at the lower part of the standing plate portion 70 is screwed to the bottom plate 1b. Is detachably attached to the body 1.

The lower portion of the front plate portion 73 is largely cut out, and the upper portion of the rear plate portion 74 is also cut out.
Thus, air flows from the cutout portion of the front plate portion 73 to the cutout portion of the rear plate portion 74 in the board case 7, and the circuit board 6 in the board case 7 is protected from heat damage. Further, the circuit board 6 is protected from spills by the board case 7. In the figure, reference numeral 75 denotes a cord holder attached to the front plate 73.

The circuit board 6 is composed of a board body 60 on which various circuit elements 60a are mounted, and a dish-shaped resin holder 61 on which the board body 60 is mounted. The circuit board 6 is attached to the board case 7 in the state of being held. The holder 61 is formed with a pair of front and rear projecting pieces 61a, 61a projecting upward and a pair of front and rear projecting pieces 61b, 61b projecting downward. A pair of front and rear embossed portions 70b, 7
0b is formed. Further, a lower embossed portion 70c bulging rightward and a receiving piece 70d cut and raised rightward are formed below the standing plate portion 70. Then, the lower rear projection 61b of the holder 61 is inserted into an engagement hole (not shown) formed in the receiving piece 70d, and the lower front projection 61b of the holder 61 is inserted into a pair of front and rear formed in the embossed portion 70c. With the lower edge of the holder 61 engaged with the small protrusions 70e, the holder 61 is brought into contact with the embossed portion 70c to position the holder 61 with respect to the upright plate portion 70. The pair of projecting pieces 61a, 61a

Can be stored. That is, the pockets 76 for accommodating the check sheet can be constituted by the gaps. still,
In this embodiment, a pair of upper and lower ribs 61c, 61c extending in the front-rear direction is formed on the back surface of the holder 61 so that the check sheet 9 does not shift up and down. A slit-shaped opening 73a facing the pocket 76 is formed in the pocket 76 so that the check sheet 9 can be inserted into and removed from the pocket 76 through the opening 73a. An indication 71a indicating that the check sheet 9 is stored is provided on the upper plate portion 71 of the substrate case 7 by engraving or the like so that the storage location of the check sheet 9 can be checked at a glance. A tape 9a serving as a knob is attached to an edge of the check sheet 9 so that the check sheet 9 can be easily pulled out from the pocket portion 76.

Here, since the substrate case 7 is maintained at a relatively low temperature as described above, the pocket portion 7 of the substrate case 7 is formed.
The check sheet 9 stored in 6 is also maintained at a relatively low temperature, and there is no problem even if plain paper is used as the check sheet 9. Also, for maintenance, in most cases,
The circuit board 6 is inspected by taking the board case 7 out of the apparatus. Since the check sheet 9 also describes the check items of the circuit board 6, the check sheet is provided in the pocket 76 of the board case 7. Storing 9 is convenient for maintenance work.

Although it is possible to form a pocket portion by attaching a separate frame to the board case 7, the pocket portion 76 is formed by a gap between the board case 7 and the circuit board 6 as in the above embodiment. This is advantageous because the cost is lower.

As shown in FIG. 5, a side plate 61d straddling a pair of upper and lower ribs 61c, 61c is formed on the back side of the holder 61 of the circuit board 6, and the holder 61 is provided with a check sheet 9 for the check sheet 9. A pocket 76 may be provided.
