(産業上の利用分野)
本考案は主として高効率湯沸器で発生する酸性
度の高いドレンを処理するドレン処理装置に関す
る。[Detailed Description of the Invention] (Industrial Application Field) The present invention mainly relates to a drain treatment device for treating highly acidic drain generated in a high-efficiency water heater.
(従来の技術)
高効率湯沸器に於いては酸性度の高いドレンが
発生する。(Prior Art) In high-efficiency water heaters, highly acidic condensate is generated.
このドレンは酸性度が高いためドレン排水管路
等を腐蝕させる不都合がある。 Since this drain has a high acidity, it has the disadvantage of corroding drain drainage pipes and the like.
これを防ぐため給湯器に中和装置を組付けてか
かる不都合を解消するものが、特開昭56−168055
号公報等に開示されている。 In order to prevent this, a neutralization device was installed in the water heater to eliminate this inconvenience.
It is disclosed in the publication number etc.
(考案が解決しようとする問題点)
しかし該中和装置に用いられる中和剤は、長期

案されている(特開昭61−44246号)。(Problems to be Solved by the Invention) However, when the neutralizing agent used in the neutralizing device is used for a long period of time, its neutralizing ability decreases. Therefore, it becomes necessary to replace it as appropriate, and there are inconveniences such as the replacement being troublesome. Therefore, a method has been proposed in which the drain is diluted by mixing it with water supply (Japanese Patent Application Laid-open No. 44246/1983).

該ドレンが給水管側に逆流するの恐れが有る。 However, this system only communicates the water supply pipe with the passage that discharges the condensate to the outside via a bypass device. A part of the water supply is always drained through the passage, but also
When the water pressure inside the water supply pipe drops, there is a risk that the drain may flow back into the water supply pipe.
本考案はかゝる不都合のないドレン処理装置を
得ることを目的とする。 The object of the present invention is to obtain a drain treatment device free from such inconveniences.

を介在させて成る。(Means for Solving the Problems) In order to achieve the above object, the present invention provides a first stop water heater equipped with a gas burner as a heat source and a water heat exchanger heated by the gas burner. A passage with a water receiving tank is provided to discharge the condensate generated in the water heat exchanger to the outside, and the water receiving tank is made to face the water inlet of the water supply channel branching from the water supply pipe, and the water supply channel is heated. An on-off valve is interposed that opens when water is passed through the exchanger.

This figure shows a water heater main body of a first stop type, which is equipped with a drain passage 4 consisting of a drain pipe 4b for discharging water to the outside, and a hot water outlet pipe 5 connected to the water heat exchanger 3 having a plurality of hot water outlet branch pipes 5a. Be prepared. In the drawing, 6 is the outlet at the tip of each branch pipe 5a, and 7 is each branch pipe 5a.
Shows the tap installed in the hot water tap.

流れ込む不具合を解消出来る。 In the present invention, the passage 4 is provided with a water receiving tank 12, and the water supply water pipe 10 is branched from the water supply pipe 9 to the water heat exchanger 3, and the water supply pipe 9 is connected to the water receiving tank 12. The water supply port of the branched water supply channel 10 was faced, and an on-off valve 11 that opened when water was flowing to the heat exchanger was interposed in the water supply channel 10. By providing the water receiving tank 12 above the discharge pipe 4b and supplying water to it from the water supply port of the water supply channel 10, even if the water supply pressure on the water supply pipe 9 side decreases for some reason, It is possible to eliminate the problem that the drain flowing into the passage 4 flows into the water supply pipe 9 side.

湯口6に湯が得られる。 When any of the hot water taps 7 is opened, water is supplied to the water heat exchanger 3 via the water supply pipe 9, and in conjunction with the water flow operation, gas is supplied to the gas burner 2 to start combustion, and the water heat exchanger 3 heat up. Therefore, hot water is obtained at the tap 6.

に解けて強い酸性を示す。 During this combustion, condensate is generated in the water heat exchanger 3 portion, and the sulfur content contained in the combustion gas is combusted to become sulfuric acid gas, which is dissolved in the condensate and exhibits strong acidity.

4その他が腐蝕する等の不都合を解消出来る。 However, this drain is always discharged via the water supply channel 10 when the water heater is in operation.
It is diluted by the water supply flowing inside and sent out. Therefore, inconveniences such as corrosion of the passage 4 and other parts due to highly acidic drain can be eliminated.

る。 Note that the hot water outlet 6 at the tip of the hot water pipe 5 is connected to the main body 1 of the water heater.
If the drain is nearby, the drain can be diluted by discharging it into a water pipe or the like connected to a water tank (not shown) that drains the hot water from the hot water outlet 6, but this type of treatment is not possible. For example, if the hot water outlet 6 is located far from the water heater main body 1, or if the hot water outlet 6 is provided with a plurality of hot water branch pipes 5a as shown in FIGS. This is particularly advantageous when applied to a case where the drain is to be disposed of outside, ie, where the drain is not flushed with the hot water from the spout 6.

得られるの効果がある。(Effects of the invention) As described above, according to the invention, a passage for discharging condensate to the outside is provided with a passage having a water receiving tank for discharging the condensate generated in the water heat exchanger to the outside,
The water receiving tank faces the water supply port of the water supply channel that branches from the water supply pipe, and the water supply channel is equipped with an on-off valve that opens when water is flowing to the heat exchanger, so that only when water is being supplied to the water heat exchanger. In other words, when the water heater is in use, a portion of the supplied water can be supplied to the water receiving tank, eliminating wasteful discharge of water, and the water receiving tank separates the water supply pipe from the passage for discharging the drain to the outside. As a result, there is no problem with condensate flowing back into the water supply pipe, and in a stop-start water heater, the condensate can be reliably diluted with water and discharged to the outside. effective.
