この考案は瞬間ガス湯沸器等の給湯器における
水抜き装置に関する。[Detailed Description of the Invention] This invention relates to a water draining device for a water heater such as an instantaneous gas water heater.
瞬間ガス湯沸器等において凍結防止等のために
器体内の水抜きを行うものであるが、従来より一
般に使用されているものは自然流下方式の水抜き
装置で、また、エアーチヤージが有効に行われ難
く、したがつて、水平方向に配設された熱交換器
（吸熱パイプ）内の残留水を完壁に抜き取ること

抜き部を設けたものは実開昭57−32352号公報に
見られるが、このものは自然流下方式を採つてい
るので充分に水抜きを行うには熱交換器を水抜き
時に傾斜させなければならず、また、熱交換器部
の水抜きに限定される等の不利があつた。 In instant gas water heaters, etc., water is removed from the inside of the container to prevent freezing, etc., but the water removal device that has been commonly used is a gravity flow method, and air charging is not effective. Therefore, it is difficult to completely drain the residual water in the horizontally arranged heat exchanger (endothermic pipe). Therefore, in order to completely drain the water inside the heat exchanger, a device in which a water drain section that can be opened and closed is provided at both ends of the heat absorption pipe can be seen in Japanese Utility Model Application Publication No. 57-32352. In order to drain water sufficiently, the heat exchanger had to be tilted when draining water, and there were also disadvantages such as being limited to draining water from the heat exchanger section.
この考案は放出水流による吸引力を有効に利用
して器体内の水抜きを強制的に行い従来不可能で
あつた熱交換器内の残留水までも完壁に抜き取り
凍結等による器具の破損等の防止を図ることを目
的とする。 This device effectively utilizes the suction force generated by the discharged water flow to forcefully drain the water inside the heat exchanger, completely removing residual water inside the heat exchanger, which was previously impossible, and preventing damage to the equipment due to freezing. The purpose is to prevent

具外へ導いてもよいこと勿論である。 Figure 1 shows the state when hot water is tapped, and Figure 2 shows the state when water is drained. An and-tube heat exchanger, 1 is a water supply pipe connected to the water inlet side of the heat absorption pipe 5 of the heat exchanger A, 2 is a hot water outlet pipe connected to the hot water outlet side of the heat absorption pipe 5 of the heat exchanger A, V 1 is a three-way valve on the water supply side that is provided in the middle of the water supply pipe 1 and has a substantially T-shaped passage;
V2 is a three-way valve on the hot water outlet side that is provided in the middle of the hot water outlet pipe 2 and has a substantially T-shaped passage, and although both three-way valves V1 and V2 are not shown, their opening and closing switching operations are synchronized with a single operation. It is provided so that it can be carried out. Reference numeral 3 denotes a draining bypass pipe to which the three-way valves V 1 and V 2 are connected, and an aspirator B is provided in the middle of the draining bypass pipe 3 . This aspirator B is a three-way valve on the water supply side.
The nozzle inner pipe 6 is connected to the upstream side 1a of the water supply pipe 1 via V 1 and is connected to the tap water outlet pipe via the three-way valve V 2 on the outlet side. The upstream side 2a of the bypass tube 3 is surrounded by an outer tube 7 at the tip of the downstream side 3b of the bypass tube 3, and the water stored in the outer tube 7 is strongly sucked by the ejector action of the water jet jetted from the inner nozzle tube 6. Exhaust pipe 9
The structure is such that it is discharged. 8 is the water supply side three-way valve
This is a substantially L-shaped air charge hole provided in V1 . Further, V 3 is a water supply valve provided on the upstream side 1a of the water supply pipe 1, and V 4 is a water supply valve provided on the downstream side 2b of the hot water outlet pipe 2.
10 is a main burner that heats the heat exchanger A, 11 is a pilot burner, 12
1 is a gas nozzle, and 13 is an inner shell. In the embodiment, the drain pipe 9 of the aspirator B is connected to the downstream side 2b of the hot water outlet pipe 2, but it goes without saying that the drain pipe 9 may be led out of the appliance as appropriate.
前記構成において、通常の出湯時は給水側三方

滑、確実に行われるものである。 In the above configuration, during normal hot water tapping, the three-way valve V1 on the water supply side communicates the upstream side 1a of the water supply pipe 1 with the heat exchanger A, and the three-way valve V2 on the hot water supply side communicates the heat exchanger A with the downstream side of the hot water tap pipe 2. It communicates with side 2b, and the drainage bypass is closed (see Figure 1). Therefore, water is supplied to heat exchanger A and hot water is discharged from heat exchanger A smoothly and reliably.

るものである。 Next, when draining water, the three-way valves V 1 and V 2 are rotated in conjunction with a single operating knob and switched to the drain position, and the water supply side three-way valve V 1 connects the upstream side 1a of the water supply pipe 1 and the water drain. The water supply side 3a of the bypass pipe 3 for draining is connected to form a water passage to the aspita B, and the hot water outlet side three-way valve V2 bypasses the upstream side 2a of the hot water outlet pipe 2 and the hot water outlet side 3b of the bypass pipe 3 for draining water. Further, the downstream side 1b of the water supply pipe 1 is communicated with the atmosphere via the air charge hole 8 (see FIG. 2). Then, open the hot water tap V4 , and
When water supply valve V 3 is opened and water is passed through the water supply channel to aspirator B, nozzle inner pipe 6 of aspirator B
A water stream is vigorously ejected from the outer pipe 7, and the water stored in the hot water outlet pipe 2 and the water supply pipe 1 is forcibly sucked in by the ejector action, and the water is forcibly sucked out from the downstream side 2b of the hot water outlet pipe 2 through the drain pipe 9. Water supply pipe 1 that is discharged with water flow
Also, the water stored in the tapping pipe 2 and the residual water in the heat exchanger A are completely removed. Here, since the air charge hole 8 communicates with the atmosphere and forms a series of drainage passages including the inside of the heat exchanger A, the water inside the appliance can be drained smoothly, reliably, and quickly. .

用不能となる等を防止できる有効なものである。 As explained above, this invention provides a water supply pipe and a hot water supply pipe in a bypass pipe for draining water so that they can be communicated with and disconnected from each other.
An aspirator that sucks hot water from the hot water outlet pipe is installed in the bypass pipe, and by simply switching the two three-way valves installed on the water supply pipe and hot water outlet pipe sides with a single operation, the aspirator is connected to the upstream side of the water supply pipe and the water supply pipe. It communicates with the hot water outlet side of the bypass pipe for draining, and the downstream side of the water supply pipe is opened to perform air charging, and the water supply is jetted from the nozzle inner pipe of the aspirator, and the water in the vessel is forcibly drained by the suction force of the water flow. Because this process is carried out at the same time, even residual water in the heat exchanger, which was previously impossible, can be completely removed. Therefore,
This is effective in preventing equipment from being damaged or temporarily rendered unusable due to freezing.
