Description

The present invention relates to an installation structure of a combustion device that facilitates drain water treatment of a wall-through type combustion device.

The installation form of a domestic water heater is generally a type installed on the outdoor wall surface of a building or a type installed on the ground. In recent years, hot water heaters using latent heat recovery type combustion equipment with high thermal efficiency have been required from the viewpoint of global warming prevention and energy saving, and those with a reheating function are often used for convenience. Such a wall-mounted type latent heat recovery type water heater with a reheating function is generally said to be a latent heat recovery type water heater with a reheating function.

  FIG. 5 shows an installation example of this latent heat recovery type hot water heater 35 with a reheating function (hereinafter referred to as “hot water heater”), and shows a perspective view when viewed from the short side of the bathtub. Various pipes are connected to the water heater. These pipes include a water supply pipe 21 for supplying water to the water heater, a hot water supply pipe 22 for supplying hot water heated by the water heater, a gas pipe 23 for supplying fuel to the water heater, and water heating. It consists of a drain water discharge pipe 27 for discharging the generated acidic drain water to the outside of the water heater through the neutralization vessel, a bath outlet pipe 25 for circulatingly heating the bath water, and a bath return pipe 24.

  The bath outlet pipe 25 and the bath return pipe 24 are connected to a circulation fitting 36 attached to a bathtub 29. The drain water discharge pipe 27 is connected in a non-contact manner to a drain outlet 37 for discharging drain water to the sewer pipe. An apron 31 for concealing the piping is attached to the bathtub 29. The apron 31 is generally detachable because it is removed during maintenance of piping and the like.

FIG. 7 is a front view of the water heater body. Below the water heater 35, a water supply pipe connection 2 connected to the water supply pipe 21, a hot water supply pipe connection 17 connected to the hot water supply pipe 22, and a gas pipe connection connected to the gas pipe 23. Section 18, a bath outlet pipe connection section 19 connected to the bath return pipe 25, a bath return pipe connection section 20 connected to the bath return pipe 24, and a drain pipe connection section connected to the drain pipe 6. 7.
The main body front cover 26 is detachable, and is removed at the time of equipment installation or maintenance. A neutralization container filled with a neutralizing agent for neutralizing acidic drain water generated in the latent heat recovery section is built in the water heater.

  On the other hand, a balance-type bath pot (hereinafter referred to as “BF pot”), which is a type of the above-mentioned water heater and is mainly installed in an apartment building and beside the bathtub, requires installation space in the bathroom. The bathtub space is narrowed accordingly. For this reason, by replacing all the functions of the BF kettle to the supply / exhaust tube installation part of the BF kettle opened on the wall surface of the BF kettle as a replacement for this BF kettle, Bathroom remodeling products that can make the bathtub large are being developed. Such a bath tub is said to be a wall-penetrating water heater with a chasing function (hereinafter referred to as a “wall-through tub”).

  FIG. 6 shows a perspective view when the wall penetration pot is installed in the bathroom and viewed from the short side of the bathtub. Various pipes are connected to the wall penetration pot main body 1. These pipes include a water supply pipe 21 for supplying water to the wall penetration kettle, a hot water supply pipe 22 for supplying hot water heated by the wall penetration kettle into the bathroom, a gas pipe 23 for supplying fuel to the wall penetration kettle, It consists of a bath outlet pipe 25 and a bath return pipe 24 for circulatingly heating the bath water.

  The bath outlet pipe 25 and the bath return pipe 24 are connected to a circulation fitting 36 attached to a bathtub 29. The hot water supply pipe 22 is connected to a faucet 38 installed on the upper edge surface of the bathtub 29. A removable apron 31 is attached to the bathtub 29.

  As a feature of the wall-through kettle, all pipes for water supply, hot water supply, gas, etc. are completed in the bathroom, and all maintenance work is also performed from inside the bathroom. Combustion air is sucked into the instrument body from the outside using the intake port 33, and combustion exhaust gas is discharged to the outside through the exhaust port 32.

  A front view of the wall penetration pot main body is shown in FIG. Below the wall penetration pot main body 1, a water supply pipe connection part 2 connected to the water supply pipe 21, a hot water supply pipe connection part 17 connected to the hot water supply pipe 22, and a gas connected to the gas pipe 23. It has a pipe connection 18, a bath return pipe connection 19 connected to the bath return pipe 25, and a bath return pipe connection 20 connected to the bath return pipe 24. The main body front cover 26 is detachable, and is removed at the time of equipment installation or maintenance.

  By the way, in any of the latent heat recovery type combustion devices such as the hot water heater, the BF kettle, and the wall through kettle described above, nitrous acid gas components and the like are contained by condensation during the heat exchange for the latent heat recovery. Strongly acidic drain water is generated. If this drain water is discharged as it is, the metal part may be corroded or the concrete may be deteriorated. Therefore, it is necessary to perform a neutralization treatment using a neutralizing agent before discharging.

  As this neutralizing agent, calcium carbonate is generally used. The shape of calcium carbonate is granular, and has the property of being aged over time when used for a long time. Since the powder will flow out of the neutralization vessel, it must be periodically replenished with calcium carbonate.

Normally, the neutralization container is built in the main body cover, and it is difficult to observe the reduction of calcium carbonate from the outside of the neutralization container, so remove the front cover from the main body in a water heater installed outdoors, A method of checking and replenishing the remaining amount of calcium carbonate in the built-in neutralization container is used.
On the other hand, in the wall penetration pot, the following method is taken. That is, remove the bathtub apron, remove the faucet pipe installed on the upper edge of the bathtub, remove the bath return pipe and the bath return pipe from the circulation fitting attached to the side of the bathtub, and then pull out the bathtub to the bathroom washing area. . Next, various pipes are removed from the main body pipe connection part, the front cover of the main body is removed, the neutralization container built in the main body is pulled out, and calcium carbonate is replenished into the neutralization container.
In this way, the remaining amount of calcium carbonate and replenishment work, including in the case of a water heater, are generally troublesome, especially in the case of a wall-through kettle, because it is difficult to move the bathtub. It has become.

  Therefore, a method for making it possible to know the replenishment time using a pH meter that detects the pH of the drain water, and a method for predicting the consumption of the neutralizing agent with the integrated value of the combustion heat amount and the combustion time (Patent Document 1). Etc. are considered.

Moreover, the neutralization container (patent document 2) which can confirm the reduction | decrease degree of the neutralizing agent from the outside, and which can be replaced disposable, and the water heater which mixes and dilutes drain water with hot water drainage etc., and does not use a neutralizing agent. (Patent Document 3) is considered.
JP 2000-337631 A No. 2001-259658 JP 2002-048413 A

  However, in the method shown in Patent Document 3, since a neutralizing agent is not used at all, it is unclear whether the pH of the drain water is always at a harmless level. For example, only hot water filling in a bathtub is performed. In such a case, only drain water is discharged, and in other cases, such as when there is a situation where the amount of hot water drainage or soap used is small, there is a possibility that the neutralization treatment is not performed sufficiently.

  In the method shown in Patent Document 1, the replenishment time can be managed by predicting the lifetime of the neutralizing agent, but the troublesomeness of the replenishment work itself cannot be solved. In particular, the wall-through hook requires the movement of the bathtub, so that the difficulty of the replenishment work itself cannot be solved due to the uniqueness of the installation.

  The same applies to the method disclosed in Patent Document 2, and even a disposable neutralization container cannot solve the trouble of managing the remaining condition or replacing work depending on the size, shape, and installation location. In particular, since the installation space is limited in the wall-through hook, there is a problem in that it is difficult to install in the main body because the size of the main body of the combustion device containing the neutralization container is limited.

  The volume of the neutralization vessel needs a certain amount of calcium carbonate to neutralize the acidic drain water, and there is a limit to downsizing. In order to incorporate this neutralization container into the wall penetration pot main body, the volume in the main body must also be increased. For that purpose, a method of increasing the opening area of the wall penetrating portion or increasing the depth of the main body can be considered.

  However, as for the former, since the opening of the wall penetrating part conventionally uses the air supply / exhaust port of the BF hook, the opening cannot be enlarged further. Moreover, about the latter, a problem arises when installing a wall penetration pot in the common hallway side. That is, in this case, the chamber chamber must be provided, but since the depth dimension of the chamber chamber is determined, if the depth of the main body of the wall penetrating pot is further increased, it will contact the wall surface of the chamber chamber, The problem that the wall penetration hook cannot be installed occurs.

The present invention has been made to solve the above-described problems, and provides an installation structure for a combustion device that includes a neutralization vessel without increasing the volume of the wall-through hook body and can reliably treat drain water. The purpose is to do. Furthermore, it aims at reducing the replenishment work at the time of aged deterioration of calcium carbonate.

(1) The present invention is a combustion device having a wall penetration pot main body, a neutralization container for neutralizing drain water generated in the wall penetration pot main body, and a drain pipe for guiding the drain water to the neutralization container; A bathtub bathed or chased by the combustion device; a bathroom floor surface on which the bathtub is placed; and a bathroom wall on which the wall penetrating pot body is installed; An installation structure of a combustion device that is installed in a gap between a bathroom floor surface outside the pot body, a bathtub, and a bathroom wall, and in which the neutralization container is connected to the wall penetrating pot body by a drain pipe.
(2) In (1), there is a combustion equipment installation structure in which drain water neutralized in a neutralization container is discharged into a space surrounded by a bathroom floor, a bathtub, and a bathroom wall.
(3) In (1) or (2), in the space between the outside of the bathtub and the bathroom wall, various pipes connected to the main body front cover, the neutralization container, and the wall penetration main body of the combustion equipment It is the installation structure of the stored combustion equipment.

  According to the present invention, since drain water is drained into a space surrounded by a bathtub and a bathroom wall surface in a bathroom equipped with a wall penetration kettle, it is necessary to bother to provide a pipe to the waste water treatment facility just for the drain water. There is no. Also, since drain water is mixed with hot water drainage and soapy water, diluted and neutralized, even if calcium carbonate in the neutralization vessel is deteriorated over time, strong acid drain water is prevented from being discharged as it is. can do.

Reduce replenishing operation during aging of the carbonated calcium, besides by providing the neutralization vessel without increasing the depth of the instrument body, while eliminating the constraints of the instrument installation, to ensure the processing of drain water It can be carried out. It is also possible to check and replenish the remaining amount of calcium carbonate simply by removing the apron.

The bathrooms capable of installing the combustion equipment according to the present invention include not only unit-type bathrooms, but also bathrooms of the conventional construction method in which floors and walls are constructed with tiles, etc., and bathtubs are installed. In particular, if the bathroom that used the BF kettle in the conventional construction method is installed when remodeling the wall penetration kettle, the BF kettle open / close tube installation part opened on the wall of the bathroom can be used and installed. It is effective because the bathtub can be enlarged by making the space compact.

  The wall penetration pot used in the present invention is a kind of latent heat recovery type water heater that discharges drain water, as described in the prior art. FIG. 3 is a diagram illustrating an example of installation of a bathroom in which the wall penetration pot main body is installed in a bathroom of a conventional construction method, and is a perspective view when viewed from the bathroom washing area side (longitudinal surface of the bathtub).

  Examples of pipes connected to the wall penetration kettle main body 1 include a water supply pipe 21 for supplying water to the wall penetration kettle main body 1, and a hot water supply pipe 22 for supplying hot water heated by the wall penetration kettle main body 1 into the bathroom. , A gas pipe 23 for supplying fuel to the wall penetration pot main body 1, a bath outlet pipe 25 for circulatingly heating the bathtub water, a bath return pipe 24, and a drain pipe 6.

The drain pipe 6 is connected to the neutralization container 8 from the wall penetration pot main body 1. As described in the paragraphs (0018) to (0020) of the prior art, it is generally difficult to incorporate the neutralization container 8 in the main body in the wall penetration pot. For this reason, when the neutralization container 8 for neutralizing drain water is provided outside as in the example of FIG. 3, the wall penetrating pot main body 1 and the external neutralization container 8 are connected by the drain pipe 6. The strongly acidic drain water condensed during the latent heat recovery is guided to the neutralization vessel.
At this time, as in the example of FIG. 9, when the neutralization container 8 is installed in the bathroom wall 28 that is orthogonal to the bathroom wall in which the wall penetration pot main body 1 is installed, the remaining amount of calcium carbonate in the neutralization container 8. Confirmation and replenishment operations can be performed simply by removing the apron 31, which increases convenience.

  The bath outlet pipe 25 and the bath return pipe 24 are connected to a circulation fitting (not shown) attached to the bathtub 29. The hot water supply pipe 22 is connected to a faucet (not shown) installed on the upper edge surface of the bathtub 29. It is preferable to attach the detachable apron 31 to the bathtub 29. This improves the workability of maintenance such as replacement of the neutralizing agent.

  FIG. 4 is a perspective view of the bathroom of FIG. 3 when viewed from the short side of the bathtub. On the lower side of the wall penetration pot main body 1, a water supply pipe 21, a hot water supply pipe 22, a gas pipe 23, a bath outlet pipe 25, a bath return pipe 24, and a drain pipe 6 are provided (not shown). . The main body front cover 26 and the apron 31 are preferably removable. Thereby, it can remove at the time of instrument installation, a maintenance, etc., and workability | operativity improves.

  Pipes for water supply, hot water supply, gas, etc. are all completed in the bathroom, and all maintenance work is performed from the bathroom. Combustion air is sucked into the instrument body from the air inlet 33 from the outside, and combustion exhaust gas is discharged outdoors through the exhaust port 32.

  The drain water generated by condensation during the recovery of the latent heat of the combustion exhaust gas in the wall penetration kettle main body 1 is strongly acidic by absorbing the sulfur component of the combustion exhaust gas, but the drain provided in the wall penetration kettle The water is collected in a receiver, flows down to the neutralization vessel 8 through the drain pipe 6, neutralized there, and then discharged through the drain water discharge pipe 27. For this reason, it is preferable that the neutralization container 8 is disposed below the wall penetration pot main body 1 and the end of the neutralized drain water discharge pipe 27 is opened downward. This facilitates the introduction of drain water into the neutralization vessel 8 and the drain water discharge through the drain water discharge pipe 27.

  One side of the drain water discharge pipe 27 is connected to the neutralization vessel 8, and the other side is opened toward the bathroom floor 30. Thereby, the drain water neutralized with the neutralizing agent is discharged to the bathroom floor surface 30. When the neutralization container 8 is built in the wall penetration pot main body 1, the drain water discharge pipe 27 is directly connected to the wall penetration pot main body 1 and the other is opened toward the bathroom floor 30. The drain water neutralized on the bathroom floor is discharged.

  Further, the end of the drain water discharge pipe 27 that is not connected to the neutralization container 8 is opened to a space surrounded by the bathroom floor 30, the bathtub 29, and the bathroom wall 28. As a result, the neutralized drain water can be discharged through the same drainage route as the hot water containing soap used for hot water drainage and bathing, and there is no need to install a pipe for the neutralized drain water. . Also, even if the neutralizing agent in the neutralization vessel 8 has deteriorated over time and the drain water is not sufficiently neutralized, it is diluted with hot water drainage and neutralized with soapy water, so it is discharged as it is. Can be prevented.

The bathroom floor surface 30 of the present invention is used to place a bathtub on the upper surface or serve as a washing place for the user. The material of the bathroom floor surface 30 is not particularly limited, and conventional construction methods such as tile, concrete, and wood are used. Can be used. In addition, a waterproof pan for a bathroom unit may be used, and in that case, the material is not limited, fiber reinforced plastic using SMC, BMC, etc., metal such as iron, aluminum, stainless steel, or These composite molded products can be used.
Also, the structure of the bathroom floor 30 is not particularly limited, but the hot water drainage, the soap water used for bathing, and the neutralized drain water discharged from the drain water discharge pipe 27 are gathered at the same place and mixed. It is preferable to have such an inclined structure and the same outlet. Thereby, dilution and neutralization of the drain water neutralized with hot water drainage and soap water are performed reliably.

When the bathtub 29 used in the present invention is placed on the upper surface of the bathroom floor surface 30, it is at least about 60 mm between the outside of the bathtub 29 (but not including the upper edge surface portion) and the bathroom wall 28. It is preferable that the shape has a gap. Thereby, the main body front cover 26, the neutralization container 8, and various pipes (water supply pipe 21, hot water supply pipe 22, gas pipe 23, bath outlet pipe 25, bath return pipe 24, drain pipe 6) are put in the space. Can be stored. The material is not particularly limited, and fiber reinforced plastic using SMC, BMC or the like, metal such as iron, aluminum, stainless steel, or a composite molded product thereof can be used.

  The opening position of the supply / exhaust port of the BF kettle is about 300 mm from the bathroom floor to the lower surface of the opening, and the pipe connection position 34 of the wall penetration kettle main body 1 installed there is located about 250 mm from the bathroom floor. The installation height of the neutralization container 8 must be lower than the pipe connection position 34 of the wall penetration pot main body 1 in order to introduce drain water discharged from the wall penetration pot main body 1 into the neutralization container 8. It becomes 250 mm or less. For this reason, it is preferable that the neutralization container 8 has a thickness of 50 mm or less, a height of 200 mm or less, and a width of 250 mm or less. As a result, it can be installed in the gap between the bathroom floor 30, the bathtub 29, and the bathroom wall 28, and does not have to be built in the wall penetrating pot body 1. As a result, the wall penetrating pot body There is no need to increase the size of 1 and the advantage of space saving can be utilized.

Further, the capacity of the neutralization vessel 8 is not particularly limited, but is preferably set to a volume capable of enclosing about 2 kg of granular calcium carbonate inside. Thereby, the lifetime of a neutralizing agent can be made long enough and the frequency of the maintenance for the inspection and replenishment of a neutralizing agent can be reduced.
Moreover, since the material of the neutralization container 8 must be excellent in corrosion resistance, a metal or plastic with strong corrosion resistance is used. In consideration of workability and assemblability, plastic is preferably used. Moreover, the lid | cover for putting calcium carbonate in a container is provided in the upper part of the neutralization container. The lid is preferably openable and closable from the viewpoint of maintenance workability.

Wall penetrating hook body 1, its front cover 26, various pipes connected to the wall penetrating pot body 1 (water supply pipe 21, hot water supply pipe 22, gas pipe 23, bath outlet pipe 25, bath return pipe 24, drain pipe 6) , neutralization vessel 8, the mounting position of the drain water discharge pipe 27, that are mounted between gap tub 29 and bathroom wall 28 preferably. Thereby, when confirming and replenishing the neutralizing agent in the neutralization container 8, the pipe of the water tap installed on the upper edge surface of the apron 31 and the bathtub 29 is removed, and the neutralization container is simply pulled out. 8 is exposed. For this reason, according to this invention, the operation | work which removes all the various piping required conventionally, opens the main body front cover 26, and pulls out the neutralization container 8 becomes unnecessary. For this reason, the confirmation of the presence or absence of deterioration of the neutralizing agent and the maintenance such as replacement and replenishment of the neutralizing agent when necessary are much easier than before.

Connected. The outlet portion of the hot water solenoid valve 14 is branched in two directions, one is connected to the outlet side of the bath heat exchanger 15 for boiling the bath water, and the other is connected to the bath outlet piping connection portion 19 . The outlet of the bath heat exchanger 15 is connected to a circulation pump 16 for circulating bath water, and the circulation pump 16 is connected to a bath return pipe connection 20. In the hot water supply combustion, the fuel gas supplied from the gas pipe connection 18 is supplied to the hot water supply combustion unit 12 via the hot water supply electromagnetic valve 13 and burned to generate high-temperature combustion gas. The combustion gas passes through the hot water supply primary heat exchanger 11, passes through the secondary heat exchanger 10, and is exhausted from the hot water supply exhaust port 4 to the outside of the appliance. At this time, since the temperature of the combustion gas passing through the secondary heat exchanger 10 is as low as about 200 ° C., dew condensation water is generated in the secondary heat exchanger 10. Since the condensed water is strongly acidic at about PH2, it must be recovered, neutralized and discharged. Condensed water generated in the secondary heat exchanger 10 is dropped and collected by the receiving plate 5 for collecting it, which becomes drain water, flows into the drain pipe 6 and passes through the drain pipe connecting portion 7. Into the inlet of the neutralization vessel 8 filled with calcium carbonate 9. The drain water neutralized in the neutralization container 8 becomes about PH7 and is discharged from the outlet of the neutralization container.
