The present invention relates to a coherent channel heat source, and more particularly, a first heat exchanger for hot water supply and a second burner, in which a first burner and a second burner are simultaneously installed in a single tube and heated by a first burner on the upper portion of the tube. Applications other than hot water being heated by means of, for example, a consistent heat source unit provided with a second heat exchanger for heating and bathroom.

Conventionally, as the heat source group, the air supply chamber separated by the distribution plate is formed at the lower part of the tube, and the space in the tube between the distribution plate and the arrangement of the first and second heat exchangers is first divided by the partition wall standing upright in the distribution plate. The chamber is separated into two chambers of the first combustion chamber equipped with a burner and the second combustion chamber equipped with a second burner, and the combustion air from the combustion fan is supplied to the first and second combustion chambers through distribution holes formed in the distribution plate in the air supply chamber. It is known to refer (for example, refer patent document 1).

Then, each heat exchanger is configured to have its own endothermic fins, and both heat exchangers are installed so that a space is formed between the endothermic fins of the first heat exchanger and the endothermic fins of the second heat exchanger, and the endothermic fins of both heat exchangers The upper end part of a partition wall is inserted in the space | interval between them. According to this, the first heat exchanger is heated by heat conduction in the second heat exchanger during the single operation of burning only one burner of the first and second burners, for example, the second burner to heat the second heat exchanger. The problem that the combustion exhaust of the second burner flows to the first combustion chamber side and the first heat exchanger is heated can be prevented.

Therefore, in the above-described conventional example, since each heat exchanger is configured to have its own endothermic fins, it is necessary to assemble each heat exchanger individually, which requires a lot of labor for assembly and high cost. The endothermic fins for the first and second heat exchangers, which are integrated channel type heat source groups without partition walls, are composed of common fins, and endothermic tubes for each heat exchanger are provided at portions corresponding to the first and second heat exchangers of the common fins. It is known to penetrate and arrange two stages up and down (for example, refer patent document 2). According to this, it is not necessary to separately assemble a 1st and 2nd heat exchanger, the assembly of both heat exchangers becomes easy, and cost reduction can be aimed at.

Therefore, also in the prior art example described in the said patent document 1, it is preferable to comprise the heat absorbing pin for 1st, 2nd heat exchanger as a common pin, and to reduce cost, as described in patent document 2. In this state, the remaining water in the heat absorbing tube of the other heat exchanger is heated by heat transfer through the common fin during the single operation of heating only one of the first and second heat exchangers. In the case where the other side heat exchanger is the first heat exchanger, when the remaining water in the heat absorbing tube is heated, there is a possibility that the initial water temperature at the time of the next hot water supply rises and hot tapping occurs.

[Patent Document 2] Japanese Patent Laid-Open No. 2000-291949 (paragraph 0013, Fig. 1)

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and the first and second heat exchanger endothermic fins are configured as a common fin to reduce costs and at the same time in a single operation of heating only one heat exchanger, It is an object of the present invention to provide a heat exchanger with a monolithic channel capable of effectively preventing the retention water heating.

In order to achieve the above object, the integrated channel type heat source of the present invention includes a first heat exchanger for a hot water supplying a first burner and a second burner together with a first burner in the upper part of the pipe, and a second burner. It is a coherent channel type heat source group provided with a second heat exchanger for use other than a hot water heated by a heating system, and forms an air supply chamber divided by a distribution plate at the lower part of the pipe, and at the same time, the arrangement portion of the distribution plate and the first and second heat exchangers. The space in the tubular body is divided into two chambers, a first combustion chamber in which the first burner is disposed and a second combustion chamber in which the second burner is disposed, by a partition wall standing upright on the distribution plate, and the combustion air from the combustion fan is divided. The supply chamber is supplied to the first and second combustion chambers through distribution holes formed in the distribution plate, and the endothermic fins for the first and second heat exchangers are configured as common pins, and the parts corresponding to the first and second heat exchangers of the common pins are Each column In providing the heat exchanger tube for at least two stages, the cutout portion extending from the lower side of the common pin to the upper and lower positions of the lower endothermic tube of each heat exchanger at the boundary between the first and second heat exchangers of the common fin. And an upper end of the partition wall is inserted into the incision.

According to the above configuration, the heat absorbing fins for the first and second heat exchangers are integrally connected to the upper portion rather than the cutout portion, and the heat conduction between the heat absorbing fins of the both heat exchangers is performed through the upper fin portion of the cutoff portion which is integrally connected. have. Here, although the lower part of each heat sink fin becomes relatively high near each burner, the heat conduction between the heat sink fin lower parts of both heat exchangers is prevented by a cutout. On the other hand, the upper part of each heat absorbing fin does not become very hot because the combustion exhaust after heat exchange with the heat absorbing tube at the lower end flows. In addition, a part of the air supplied to each combustion chamber through the distribution hole of the distribution plate in the air supply chamber flows upward along the wall surface of the partition wall, so that the partition wall is air-cooled and the upper fin portion of the incision portion into which the upper end of the partition wall is inserted. It is also air cooled. Therefore, during the sole operation of heating only one heat exchanger of the first and second heat exchangers, the heat conduction of the other heat exchanger to the heat absorbing fins through the upper fin portion of the cutout is effectively suppressed, and through the partition wall to the other heat exchanger. The heat conduction of is also suppressed, and the heating of the remaining water in the heat absorption tube of the other heat exchanger is effectively prevented.

In order to generate cooling air flow reaching the upper fin portion of the cutout portion along the outer wall surface of the partition wall, a space between the partition wall and each burner and a gap between the cutout portion and the heat absorbing tube at the lower end of each heat exchanger are respectively widened. You need to secure it. On the other hand, if the partition wall is composed of two plates facing each other at intervals, and the air from the air supply chamber flows in the gap between the two plates, the partition wall is formed without generating cooling air flow along the outer wall surface of the partition wall. At the same time, the upper fin portion of the cutout is also cooled by air taken out between the upper edges of both plates. Therefore, the space | interval between a partition wall and each burner, and the space | interval between a partition and the lower end heat absorbing tube of each heat exchanger can be narrowed, and the heat source machine can be made compact. In addition, cooling of the heat absorbing fins is also suppressed by the cooling air flow flowing between the cutout and the lower heat absorbing tube of each heat exchanger, thereby preventing a decrease in thermal efficiency.

In addition, when the upper end of the partition wall is brought into close contact with the side edge of the cutout portion, the partition wall is heat-exchanged by water flowing into the heat absorbing tube at the lower end adjacent to the cutout portion, whereby the partition wall is cooled more efficiently. Therefore, in the single operation of heating only one heat exchanger, the heat transfer through the partition wall can prevent the heating of the other side heat exchanger more effectively.

And, if the pipe is composed of the upper half and the lower half, which can be separated up and down, the distribution plate and both burners can be assembled in the lower half and the heat exchanger can be assembled in the upper half before assembling the tube by combining the upper half and the lower half. This is improved. In addition, since the material of the upper half and the lower half can be changed, cost reduction can be achieved. In this case, if the partition wall is also composed of the upper half and the lower half, which can be easily separated up and down, the lower half of the partition wall can be attached to the distribution plate in advance, so that assembly performance can be prevented from being degraded only by providing the partition wall.

In addition, a partition plate is provided which divides the air supply chamber into two chambers of the first air supply chamber directly below the first combustion chamber and the second air supply chamber directly below the second combustion chamber, and burns each of the first air supply chamber and the second air supply chamber with separate combustion fans. It is also possible to supply air. That is, according to the present invention, the specification of the heat source machine can be easily changed from one fan type to two fan types by only partitioning the air supply chamber into two chambers. Here, in the case where the partition wall is composed of two plates facing each other at intervals, it is preferable that the air from the second air supply chamber flows through the gap between the two plates. According to this, even if the combustion amount of a 2nd burner changes in the single operation which heats only a 2nd heat exchanger, the space | interval between the two plates of a partition wall is changed by the change of the supply air volume to the 2nd air supply chamber corresponding to the combustion amount of a 2nd burner. The amount of cooling air flowing through changes with respect to the combustion amount of a 2nd burner, and a partition wall is air-cooled without excess or deficiency. Therefore, the water retained in the endothermic tube of the first heat exchanger for hot water supply does not become high temperature due to lack of air cooling of the partition wall or low temperature due to excessive air cooling of the partition wall, thereby facilitating hot water management at the time of refueling.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a first burner 2-1 and a second burner 2-2 in a single tube 1, and at the same time as the first burner 2-1 at the top of the tube 1; A constant channel-type heat source group formed by combining a heated first heat exchanger 3-1 and a heated second heat exchanger 3-2 heated by the second burner 2-2 is shown.

Each of the burners 2-1 and 2-2 has a configuration in which a plurality of rectangular unit burners 2a are arranged in the transverse direction in the depth direction (the orthogonal direction of the paper in Fig. 1) of the tubular body 1, respectively. Gas is supplied through each nozzle 2c which provided the gas manifold 2b for each burner 2-1, 2-2 in (2a). Since the hot water supply demands a larger heating capacity than the heating, the number of the unit burners 2a constituting each of the burners 2-1 and 2-2 is configured to have a greater number of first burners 2-1. .

In the lower part of the tubular body 1, the air supply chamber 5 partitioned with the distribution board 4 with respect to the space in the tubular body 1 is formed. In addition, the space in the tubular body 1 between the distribution plate 4 and the arrangement | positioning part of the 1st, 2nd heat exchanger 3-1, 3-2 is the partition wall (uprightly standing upright from the distribution plate 4) 6), the chamber is divided into two chambers, the first combustion chamber 7-1 in which the first burner 2-1 is arranged and the second combustion chamber 7-2 in which the second burner 2-2 is arranged. . Then, a combustion fan 8 connected to the air supply chamber 5 is provided, and a plurality of distribution holes 4a formed in the distribution plate 4 in the air supply chamber 5 in the combustion air in the combustion fan 8 are provided. It supplies to the 1st, 2nd combustion chamber 7-1, 7-2 through the said container. Most of the combustion air supplied to each combustion chamber 7-1, 7-2 is used as primary air and secondary air for combustion of each burner 2-1, 2-2, but some are partition walls ( Cooling air stream a flowing upward along the outer wall surface of 6) cools the partition wall 6. Further, the combustion exhaust of each burner 2-1, 2-2 is discharged from each combustion chamber 7-1, 7-2 to the exhaust hood 9 above through each heat exchanger 3-1, 3-2. Flow is discharged to the outside through the exhaust port 9a formed in the exhaust hood 9.

Each of the heat exchangers 3-1 and 3-2 has a plurality of endothermic fins 3a arranged in the depth direction of the tube 1, and a meandering shape penetrating these endothermic fins 3a. It consists of the heat absorbing tube 3b. Although not shown in the endothermic pipe 3b of the first heat exchanger 3-1, the water supply pipe on the upstream side and the water outlet pipe on the downstream side are connected, and the tapping stopper at the downstream end of the tapping pipe is opened to open the first heat exchanger (3- When passing through 1), the first burner 2-1 is ignited and hot water at the set temperature is ejected from the tapping stopper. Although not shown, the heat absorbing tube 3b of the second heat exchanger 3-2 is connected to a heating circuit (not shown) such as floor heating through a crown and a return tube, and the second heat exchanger is connected to the heating circuit. The hot and cold water is circulated through the machine 3-2 to perform heating.

Here, the heat absorbing fins 3a and 3a of the first and second heat exchangers 3-1 and 3-2 are constituted by a common fin 30. Therefore, it is not necessary to assemble both the heat exchangers 3-1 and 3-2 separately, so that the cost can be reduced by reducing the assembly labor. Also, in order to improve heat exchange efficiency, endothermic tubes for heat exchangers 3-1 and 3-2 are provided at portions corresponding to the first and second heat exchangers 3-1 and 3-2 of the common fin 30. 3b) is penetrated and arranged at least in two stages up and down. In the first heat exchanger 3-2, water from the water supply pipe flows to the heat absorbing tube 3b at the upper end via the heat absorbing tube 3b at the lower end as shown by the arrow in FIG. Also in (3-2), the water returned from the heating circuit flows to the heat absorption tube 3b at the upper end via the heat absorption tube 3b at the lower end.

In addition, a lower end heat absorbing tube of each heat exchanger 3-1, 3-2 at the lower side of the common fin 30 at a boundary between the first and second heat exchangers 3-1, 3-2 of the common fin 30. The cutout part 31 extended to the position higher than the arrangement height of 3b is formed. The upper end of the partition wall 6 is inserted into the cutout 31.

According to the above configuration, the heat absorbing fins 3a and 3a of the first and second heat exchangers 3-1 and 3-2 are integrally continuous at the fin portion above the cutout 31. Here, the lower portion of each of the heat absorbing fins 3a adjacent to the first and second burners 2-1 and 2-2 is relatively high in temperature, but the upper portion of each of the heat absorbing fins 3a is exchanged with the heat absorbing tube 3b at the lower end. Because the burned exhaust flows, it does not become very hot. Further, the partition wall 6 is cooled by the cooling air flow a flowing upward along the outer wall surface of the partition wall 6, and the upper end of the partition wall 6 is inserted above the cutout portion 31. The fin section is also cooled. Therefore, in the single operation in which only one heat exchanger of the first and second heat exchangers 3-1 and 3-2 is heated, for example, as shown in FIG. In the heating alone operation in which only the heat exchanger 3-2 is heated, the cutout is made from the heat absorbing fin 3a of the second heat exchanger 3-2 to the heat absorbing fin 3a of the first heat exchanger 3-1. Thermal conduction through the upper fin portion of 31 is effectively suppressed. Then, the heat conduction from the lower end of the heat absorbing fin 3a of the second heat exchanger 3-2 to the heat absorbing fin 3a of the first heat exchanger 3-1 is blocked by the cutout 31. In addition, when the pin blockage part b is formed in the transverse outer part of the 2nd heat exchanger 3-2, as shown in FIG. 1, the flame of the 2nd burner 2-2 will move to the transverse direction inner side. Although approaching, since the heating of the partition wall 6 is suppressed by the cooling air flow a, heat transfer to the 1st heat exchanger 3-1 through the partition wall 6 is also suppressed. In this way, heat transfer to the first heat exchanger 3-1 through the upper fin portion of the cutout 31 and the partition wall 6 is suppressed at the time of heating alone, and thus the heat absorption of the first heat exchanger 3-1 is suppressed. Heating of the residual water in the pipe 3b is effectively prevented. Therefore, the initial water temperature rises during the next hot water supply, thereby preventing the occurrence of high temperature tapping.

By the way, in order to generate the cooling air flow a which reaches the upper fin part of the cutout part 31 along the outer wall surface of the partition wall 6, the partition wall 6 and each burner 2-1, 2-2. It is necessary to ensure a wide space between the gaps between the gaps) and the heat sinks 3b at the lower ends of the cutouts 31 and the heat exchangers 3-1 and 3-2, respectively. Therefore, the heat source fin is enlarged, and the heat absorbing fins 3a are cooled by the cooling air flow flowing between the cutout portions 31 and the heat absorbing tubes 3b at the lower ends of the heat exchangers 3-1 and 3-2. The thermal efficiency is lowered.

Figure 2 is to solve this problem, and shows a second embodiment of the integrated channel heat source. Incidentally, the same reference numerals are used for the same members as those of the first embodiment. Different from the first embodiment in the second embodiment, the partition wall 6 is composed of two plates 60 and 60 facing each other at intervals, and the air supply chamber is provided through the gap between the two plates 60 and 60. Air from (5) was made to flow. Therefore, effective cooling is achieved due to the cooling air flow a in which the partition wall 6 flows at its inner space without generating cooling air flow along the outer wall surface of the partition wall 6. The fin portion above the cutout portion 31 is also cooled by the cooling air stream a discharged between the upper ends of the two plates 60 and 60. Therefore, the gap between the partition wall 6 and each burner 2-1, 2-2, the cut-out part 31, and the heat absorption pipe 3b of the lower end of each heat exchanger 3-1, 3-2, and By narrowing the space between, the heat source can be compacted. In addition, cooling of the heat absorbing fins 3a is also suppressed by the cooling air flow flowing between the cutout 31 and the lower heat absorbing tubes 3b of the heat exchangers 3-1 and 3-2, thereby improving thermal efficiency. .

In addition, in the second embodiment, the upper part of the cutout part 31 is made relatively wider and the lower part thereof is made narrower so that the upper edge of the partition wall 6 is in close contact with the shape of the silencer. Thereby, heat exchange is performed by the water flowing to the heat absorption pipe 3b at the lower end adjacent to the cutout 31, and the partition wall 6 is cooled more effectively. Therefore, in the single operation of heating only one heat exchanger, heating of the heat exchanger can be prevented more effectively by heat transfer through the partition wall 6.

Fig. 3 shows a third embodiment of the integrated channel heat source machine. In the third embodiment, the tubular body 1 of the second embodiment is composed of an upper half 1U and a lower half 1L freely separating up and down, and the partition wall 6 also has an upper half 6U and a lower half 6L freely separating up and down. ). According to this, the distribution plate 4 and the both burners 2-1 and 2-2 are assembled in the lower half 1L before assembling the pipe | tube 1 by combining the upper half 1U and the lower half 1L. The heat exchangers 3-1 and 3-2 can be assembled in the upper half 1U, and the assemblability is improved. In addition, the lower half 6L of the partition wall 6 is attached to the distribution plate 4 in advance, and the common pin 30 cutouts 31 of the first and second heat exchangers 3-1 and 3-2 are also provided. The upper half 6U of the partition wall 6 can be attached in advance, so that the assembly properties can be prevented from being degraded in installing the partition wall 6. In addition, the material of the tubular body 1 can be changed into the upper half 1U (for example, copper) and the lower half 1L (for example, iron), thereby achieving cost reduction. In addition, even when the partition wall 6 is composed of one sheet as in the first embodiment, the tubular body 1 and the partition wall 6 can be configured by the upper half and the lower half freely separated up and down as in the third embodiment. have.

Figure 4 shows a fourth embodiment of a consistent channel heat source. In the fourth embodiment, the air supply chamber 5 is directly below the first combustion chamber 7-1 and the first air supply chamber 5-1 and the second combustion chamber 7-2. A partition plate 5a, which is divided into two rooms of the second air supply chamber 5-2, is installed, and separate combustion fans 8- 8 are respectively provided in the first air supply chamber 5-1 and the second air supply chamber 5-2. 1, 8-2) to supply the combustion air. According to this, the amount of air supplied to each combustion chamber 7-1, 7-2 can be suitably controlled by adding up the amount of combustion of each burner 2-1, 2-2. In the two-fan type heat source equipped with two combustion fans, a two-pipe two-channel type is generally used to store two burners in separate pipes. However, in the present embodiment, the specification of the heat source is divided into two channels. Just by installing (5a), it can be easily changed from one fan type to two fan types.

In addition, in the fourth embodiment, the two plates 60 and 60 are arranged to form the partition wall 6 by arranging the partition plate 5a adjacent to the first air supply chamber 5-1 directly below the partition wall 6. Air from the 2nd air supply chamber 5-2 flows through the space | interval between them. According to this, even if the combustion amount of the 2nd burner 2-2 changes only at the time of the heating single operation which heats only the 2nd heat exchanger 3-2, the 2nd grade corresponding to the combustion amount of the 2nd burner 2-2. Due to the change in the amount of air supplied to the gas chamber 5-2, the amount of cooling air flowing at the interval between the plates 60 and 60 of the partition wall 6 changes in correspondence with the combustion amount of the second burner 2-2, and the partition The wall 6 is air cooled without excess or deficiency. Therefore, the retention water in the heat absorption tube 3b of the first heat exchanger 3-1 for hot water supply becomes high due to lack of air cooling of the partition wall 6 or becomes low temperature due to excessive air cooling of the partition wall 6. It is easy to manage the hot water temperature at the time of refueling.

Figure 5 shows a fifth embodiment of the constant channel heat source. In the fifth embodiment, the first and second sub-heat exchangers 10-1 and 10-2 for condensation are disposed downstream of the first and second heat exchangers 3-1 and 3-2 in the fourth embodiment. The water from the water supply pipe is passed through the first sub-heat exchanger (10-1) to the first heat exchanger (3-1), and the water returned from the heating circuit is transferred to the second sub-heat exchanger (10-2). It is to be passed through the second heat exchanger (3-2) via. According to this, the water vapor in the combustion exhaust of each burner 2-1, 2-2 condenses by heat exchange in each subheat exchanger 10-1, 10-2, and each subheat exchanger 10-1. 10-2) is preheated by heat exchange by condensation of water vapor. Thus, the condensing type can be easily developed. Both sub-heat exchangers 10-1 and 10-2 are placed in a common partition 10a with a simple partition 10b interposed therebetween.

As mentioned above, although the Example which applied this invention to the integrated channel type heat source which has the 1st heat exchanger 3-1 for hot water supply and the 2nd heat exchanger 3-2 for heating was demonstrated, the 2nd heat exchanger 3-2 was demonstrated. ) May be applied to the case of a heat exchanger for a bathroom and a heat exchanger for a heating and a bathroom.

As described above, the coherent channel heat source according to the present invention comprises a common fin for the first and second heat exchanger heat sinks to reduce costs and at the same time the heat sink of the other heat exchanger in the sole operation of heating only one heat exchanger. The effect of making it possible to effectively prevent the retentive water heating inside is acquired.
