に関するものである。[Detailed description of the invention] The present invention has a hot water supply pipe and a return pipe, and a circulating pump circulates hot water from a heat source device, making it possible to immediately supply hot water when a hot water tap is opened. The present invention relates to a method of controlling a circulating water heater.

プ6は。A conventional circulating water heater of this type was constructed as shown in FIG. That is, the boiler 1 is connected to a hot water feed pipe 2 and a hot water return pipe 3, and the hot water feed pipe W2 is provided with hot water taps 4 and 5. A circulation pump 6 is inserted into the hot water return pipe 3 to circulate hot water to the hot water feed pipe 2 and the hot water return pipe 3 of the boiler 1. This circulation pump 6.

が、給湯栓4あるいは5を開成すると。Since it is provided for the purpose of dissipating and supplementing the heat from the hot water feed pipe 2 and the hot water return pipe 3, it is attached to the hot water return pipe 3 so as not to cause resistance during hot water supply. 7 is Jistan,
Normally, a little warm water is circulated by the circulation pump 6, but when the hot water taps 4 and 5 are opened.

hot water is supplied. Regarding control, since the circulation hot water system was originally intended for large-scale equipment, no special consideration was given to it, and the circulation pump 6 was turned on and off with a manual switch 8, 2 and hot water was normally constantly circulating.
この従来の循環式給湯装置は1以上述べたように構成さ
れているため1次のような欠点を有していた。Since this conventional circulating hot water supply apparatus is constructed as described above, it has the following drawbacks.
(1)給湯栓4,5への給湯は、@水速り管2のみ全通

径の配管を通例として用いていたため、配管スペース全
長く必要とし高1曲でもめ、りた。(1) To supply hot water to the hot water taps 4 and 5, only the water speed pipe 2 passes through, so the hot water feed pipe 2 needs to be thick enough to match the hot water supply 1, and the hot water return pipe 3 also feeds hot water. Since piping with the same diameter as pipe 2 was normally used, the entire piping space was required to be long, and there was a problem with just one turn in height.
(2)配管径が太いため1周囲の空気に接する面積も大
きくなり、温水循環時の放熱量が大きくなった。特に温
水は、何時でも給湯に対処できるように常時循環して予
熱しているため、この放熱針は非常に大きかった。(2) Since the pipe diameter is large, the area in contact with the surrounding air is also large, and the amount of heat dissipated during hot water circulation is large. In particular, the heat dissipation needle was extremely large because hot water was constantly circulated and preheated so that it could be used at any time.

1図とともに説明する。In order to achieve this object, the present invention provides a bypass pipe that connects the hot water feed pipe and the hot water return pipe, and a route switching valve that selects the piping route side and the bypass pipe [111J]. Detects the flow meter difference between the pipes and switches the route switching valve to the piping route side when there is no flow meter difference, allowing full circulation of hot water from the hot water sending pipe to the hot water return pipe, and switching to the bypass pipe side when there is a flow meter difference. Hot water is supplied through both the hot water supply pipe and the hot water return pipe.An enemy detection means is installed near the route switching valve, and the pipe diameters of the hot water supply pipe and water return pipe are reduced, and special wiring work is carried out. The present invention provides a circulating hot water supply device that does not require the above steps. Next, one embodiment of the present invention will be described with reference to FIG.

かれ。They are connected via a bypass pipe 20 via a route switching valve 19'fr, and the circulation pump 18 is connected to a connection part 20' of the bypass pipe 19.
connected to the upstream side of the The path switching valve 19 is controlled by a flowmeter difference detection means 23 including a flowmeter sensor [21] provided on the hot water feed pipe 14 and a flowmeter sensor [22i] provided on the hot water return pipe 16. The flow meter detection means 23 has a built-in electric circuit that calculates the flow difference between the flow meter sensor 121 and the flow sensor [22], and is also connected to a thermometer 24 that detects the temperature of the piping route. The circulation pump 18 is controlled by sharing the gold. The route switching valve 19 is @
When circulating water, the piping route side is selected, and the hot water is circulated from the boiler 12 to the boiler 12 again through a hot water feed pipe 14 and a hot water return pipe 16 using a circulation pump 18. Also, during hot water supply, the route switching valve 19 is switched to the bypass pipe 2o.
Depending on which side is selected, the hot water is led to the hot water tap 16 or the hot water tap 17 through the hot water feed pipe 14 and the hot water return pipe 16.

を繰り返す。First, it is assumed that the hot water taps 16 and 17 are closed and the temperature of the piping path is low. The thermostat 24 detects the temperature and first starts the circulation pump 18. Then, the flow meter sensor 21.1122 operates during a predetermined period of time and detects the flow meter difference between the hot water feed pipe 21 and the hot water return V pipe 22. In this case, since the hot water taps 16 and 17 are closed, there is no flow meter difference, so the path switching valve 19 continues to select the piping path side, and the hot water from the boiler 12 flows in the direction indicated by the solid line arrow in Figure 1 at a small flow rate. When the temperature of the piping route rises, the thermometer 24 detects this and stops the circulation pump 18. Below, when the temperature of the piping route falls, the circulation pump 18 starts, and when the temperature rises, the circulation pump 18 stops. The operation of the pump 18 is repeatedly stopped.

。Next, with the circulation pump 18 stopped, the hot water tap 16.
Alternatively, suppose you open any one of the 17. Normal time,
Since the route switching valve 19 selects the piping route 1llO, hot water first passes through the hot water feed pipe 14 and flows out of the hot water tap 16 or 17 due to the water head pressure of the distiller 11, but the flow 1 sensor 121 and the flow meter sensor [ 22, the path switching valve 19 is activated by the flow rate difference detection means 23. .

Since there is no difference between the flow rate sensor 21 and the flow rate sensor [22, the route switching valve 19 selects the piping route side.
By opening 6 or 17, the hot water feed pipe 14
Since there is a difference in R and amount of the hot water return pipe 16, the path switching valve 19 selects the bypass pipe 2oIIIl of the hot water supply pipe 14. In this embodiment, the circulation pump 18 is switched to the bypass pipe 2o Because it is provided upstream of the connecting portion 20', hot water can be supplied to the hot water taps 16, 17 in a pressurized state, thereby eliminating dissatisfaction such as insufficient water pressure.

できる。The present invention includes a bypass pipe and a route switching valve that connect a hot water sending pipe and a hot water return pipe, and the route switching valve is controlled by a flowmeter difference detection means that detects a difference in flow rate between the hot water sending pipe and the hot water return pipe.
When hot water is being circulated, a circulation pump is used to circulate all of the machine's hot water from the hot water sending pipe to the hot water return pipe, and when hot water is being supplied, hot water is supplied to the hot water tap through both the hot water sending pipe and the hot water return pipe. It has the following effects: (1) Hot water is supplied to the hot water faucet through both the hot water supply pipe and the hot water return pipe, and during circulation, a small flow of hot water from the hot water supply pipe to the hot water return pipe is circulated. @Water speed pipe and @Water return pipe have small diameters, requiring less piping space and can be provided at low cost.
(2)温水送り管、温水返り管とも小径で良いため周囲
空気への接触面積が減り、特に従来問題であった循環時
の放熱が大巾に低減できる。(2) Since both the hot water sending pipe and the hot water return pipe can be of small diameter, the area of contact with the surrounding air is reduced, and in particular, the heat radiation during circulation, which has been a problem in the past, can be greatly reduced.
(3)経路切換弁の制御は温水送り管と温水返り管の流

要がない。(3) Since the route switching valve is controlled by a flow rate detection means that detects the difference in flow rate between the hot water supply pipe and the hot water return pipe, it is necessary to install an operation switch near each hot water tap or perform electrical wiring work to supply hot water. There is no need to connect wires from the stopper side to the route switching valve.
