Description

  The present invention relates to a wall-embedded combustor disposed so as to be embedded in a recess formed in a chamber wall.

  Conventionally, this type of wall-embedded combustor has an outer case and a combustion housing with a burner provided in the outer case. A glass plate is attached to the front surface of the combustion housing, and the front panel of the outer case is mounted. There is known a fireplace-type heater in which a window portion that faces the glass plate on the front surface of the combustion housing is opened so that the inside of the combustion housing can be visually observed (see, for example, Patent Document 1). In this case, an electronic control unit is arranged in a side space on one side in the lateral direction between the combustion case in the outer case so that the heat influence from the combustion case can be prevented from reaching the electronic control unit. ing.

By the way, at the time of maintenance, the voltage value, resistance value, etc. of each part of the electronic control unit may be measured using a tester in a state where the combustor is trial run. Here, the lateral width of the side space cannot be increased to the left in order to save space. Therefore, the tester cannot be inserted into the side space and pressed against the electronic control unit. In this case, with a normal floor-mounted combustor, it is possible to remove the side plate of the outer case and press the tester from the side against the electronic control unit in the side space. Such a method cannot be adopted because the room wall gets in the way. For this reason, in the above-described conventional wall-embedded combustor, the operator has to take out the electronic control unit from the side space and hold it by hand and measure the voltage value, resistance value, etc. It is very troublesome.

  In view of the above points, the present invention provides a wall-embedded combustor with improved maintainability by measuring the voltage value, resistance value, etc. of each part of the electronic control unit without holding the electronic control unit by hand. The issue is to provide.

  In order to solve the above problems, the present invention provides a wall-embedded combustor disposed so as to be embedded in a recess formed in a chamber wall, and includes an outer case having a front panel, and a burner provided in the outer case. The electronic control unit is disposed in the side space between the combustion casing and the combustion casing in the outer case, and the electronic control unit is removed from the regular arrangement location in the side space. Temporary support means is provided which can be temporarily supported in a state in which is projected forward from the front edge of the side plate portion of the outer case.

  According to the above configuration, when the front panel of the outer case is removed at the time of maintenance, and the electronic control unit is removed from the regular placement location and supported by the temporary support means, the electronic control unit is exposed to the front of the outer case. Therefore, even if the electronic control unit is not held by hand, the tester can be pressed against each part of the electronic control unit to measure the voltage value, the resistance value, etc., and the maintainability is remarkably improved. Further, in the combustor assembly process, the electronic control unit can be supported by the temporary support means and the harness can be connected, and the assemblability can be improved.

  By the way, a mounting bracket for the electronic control unit for supporting the electronic control unit at a regular arrangement place is provided in the side space. If the temporary support means is integrally provided at the front end portion of the mounting bracket, it is not necessary to separately provide a part for the temporary support means, and the number of parts can be reduced and the cost can be reduced. In this case, a temporary support means is constituted by a bent portion formed in the front end of the mounting bracket and bent in the lateral direction, and an engagement hole formed in the bent portion, and protrudes into the rear side portion of the electronic control unit. If the electronic control unit is temporarily supported by engaging the provided hook portion with the engagement hole, the structure is further simplified, and screwing for temporary support is unnecessary, which is advantageous. .

  Hereinafter, an embodiment in which the present invention is applied to a fireplace heater as a wall-embedded combustor will be described. As shown in FIGS. 1 to 3, the heater includes an outer case 1 and a combustion housing 2 provided in the outer case 1. A detachable front panel 1 a is provided on the front surface of the outer case 1. Further, as shown in FIG. 3, the outer case 1 is disposed so as to be embedded in a recess Wa formed in the chamber wall W, and only the front portion of the outer case 1 is exposed in front of the chamber wall W. .

  A burner 3 is disposed in the lower part of the combustion housing 2. In addition, a burner support plate 2a for fitting the upper end portion of the burner 3 is disposed in the combustion housing 2, and a pseudo ridge 4 formed of a refractory material such as ceramics is disposed on the burner support plate 2a. Then, a glass plate 2c is attached to a front door 2b that is detachably attached to the front surface of the combustion housing 2, and a window portion 1c with a window glass 1b for opening the glass plate 2c is opened on the front panel 1a of the outer case 1. is doing. Thus, the inside of the combustion casing 2 can be visually observed from the front of the front panel 1a, and when the burner 3 is burned, a visual impression can be given as if the soot 4 is burning.

  The combustion exhaust in the combustion casing 2 is sent to the outside via a heat exchanger 5 disposed on the rear side of the combustion casing 2 and an exhaust duct 7 connected to the downstream side of the heat exchanger 5 via an exhaust fan 6. It is forcibly discharged. An air supply duct 8 is connected to the bottom of the combustion housing 2, and outdoor air is forcibly supplied into the combustion housing 2 through the air supply duct 8 by the suction force of the exhaust fan 6. The exhaust duct 7 is disposed on the left outer side of the combustion casing 2, and the front door 2 b projects to the left side of the combustion casing 2 in order to prevent radiant heat from the exhaust duct 7 from reaching the front panel 1 a. Is formed.

  In the outer case 1, a hot air fan 9 is disposed above the combustion housing 2. And while opening the air intake 10 in the front edge part of each side plate part 1d on either side of the outer case 1, the ventilation opening 11 is opened in the lower part of the window part 1c of the front panel 1a, and indoor air is air The air is sucked into the hot air fan 9 through the intake port 10 and is blown from the hot air fan 9 to the air blowing port 11 via the arrangement portion of the heat exchanger 5 and the space below the combustion housing 2 to perform the hot air heating function. I try to get it. A partition plate 2d reaching the bottom surface and the back surface of the outer case 1 is erected outside the left and right sides of the combustion housing 2 to partition the air blown from the hot air fan 9 from escaping in the lateral direction. This can be prevented by the plate 2d. A guide plate 2 e that guides the air that has passed through the arrangement portion of the heat exchanger 5 to the air outlet 11 is disposed below the combustion housing 2.

  One side (right side) side space 12 between the combustion case 2 in the outer case 1 (space between the right partition plate 2d of the combustion case 2 and the right side plate portion 1d of the outer case 1) The electronic control unit 13 and the valve unit 14 for the burner 3 are arranged. As shown in FIGS. 2, 4 and 5, the electronic control unit 13 is supported in a lateral posture by a mounting bracket 15 fixed to the upper part of the partition plate 2d. A pair of upper and lower first fixing portions 15a and 15a that are in contact with the back surfaces of the ear pieces 13a and 13a protruding above and below the front portion of the electronic control unit 13 are formed at the front portion of the mounting bracket 15. A second fixing portion 15 b that abuts against the rear side portion of the electronic control unit 13 is formed at the rear portion of 15. In addition, a pair of upper and lower hook portions 13b and 13b are projected from the rear side portion of the electronic control unit 13, and a pair of upper and lower engagement holes 15c and 15c corresponding to the hook portions 13b and 13b are provided in the second fixing portion 15b. Opened. Then, with each hook portion 13b engaged with each engagement hole 15c, each ear piece 13a is screwed to each first fixing portion 15a from the front, and the electronic control unit 13 is a mounting bracket which is a proper location. 15 is fixed.

  By the way, at the time of maintenance, a tester may be pressed against each part of the electronic control unit 13 in a state where the heater is trial run, and a voltage value, a resistance value, and the like may be measured. Here, the lateral width of the side space 12 in the outer case 1 in which the electronic control unit 13 is arranged cannot be so wide for space saving, and it is difficult to press the tester against the electronic control unit 13 in the side space 12. It is. In this case, it is also possible to remove the electronic control unit 13 from the regular location and measure the voltage value, resistance value, etc. using a tester while the operator holds the electronic control unit 13 by hand. Then, workability becomes worse.

  Therefore, in the present embodiment, temporary support means 16 that can be temporarily supported in a state where the electronic control unit 13 is detached from the mounting bracket 15 is provided in the side space 12 in the outer case 1. In detail, a bent portion 16a that is bent inward in the lateral direction is formed at the front end of the mounting bracket 15, and hook portions 13b and 13b of the rear side portion of the electronic control unit 13 are formed in the bent portion 16a. A pair of upper and lower engaging holes 16b, 16b corresponding to the above is opened, and the temporary support means 16 is constituted by the bent portion 16a and the engaging hole 16b. Note that the position of the bent portion 16a is such that the majority of the electronic control unit 13 is more than the front edge of the side plate portion 1d of the outer case 1 when the rear side portion of the electronic control unit 13 is brought into contact with the bent portion 16a. It is set to protrude forward.

  At the time of maintenance, the front panel 1a is removed, the upper and lower ear pieces 13a, 13a of the electronic control unit 13 are unscrewed, and the electronic control unit 13 is removed from the regular arrangement location shown in FIG. Next, the pair of upper and lower hook portions 13 b and 13 b on the rear side portion of the electronic control unit 13 are engaged with the pair of upper and lower engagement holes 16 b and 16 b of the bent portion 16 a on the front end of the mounting bracket 15. According to this, as shown in FIG. 4B, the electronic control unit 13 is temporarily supported in a state where it is exposed to the front of the outer case 1. Accordingly, the operator can press the tester against each part of the electronic control unit 13 without holding the electronic control unit 13 by hand to measure the voltage value, the resistance value, etc., and the maintainability is improved. Further, in the assembly process of the heater, the electronic control unit 13 can be supported by the temporary support means 16 so that the harness can be connected and the assemblability can be improved. Furthermore, since the electronic control unit 13 can be temporarily supported by merely engaging the hook portion 13b of the electronic control unit 13 with the engagement hole 16b without performing a troublesome screwing operation, the workability is further improved.

  A temporary support means 16 can be provided in the side space 12 in the outer case 1 in addition to the mounting bracket 15 for the electronic control unit 13, but at the front end of the mounting bracket 15 as in the above embodiment. Providing the temporary support means 16 integrally is advantageous in that the number of parts can be reduced and the cost can be reduced.
