する。By the way, in an automatic hot-water supply bath apparatus, a hot-water supply heat exchanger is used to pour water into a bathtub, and pouring is performed through a flow pipe among a go-seki and a return pipe constituting a circulation path leading to the bath tub. . Normally, the return pipe is not used when pouring.
This is because a change in the level of hot water in the bathtub cannot be detected during pouring because the return pipe is provided with means for detecting the water level in the bathtub by pressure. Therefore, in order to increase the amount of molten metal poured into the bathtub using only the outgoing pipe, a high pressure is required, and the outgoing pipe must have a high withstand pressure and a large cross-sectional area. Further, since a large amount of hot and cold water flows, the inner surface of the going pipe is subjected to great friction, which causes dissolution or destruction of the inner surface of the going pipe and also causes corrosion, that is, erosion which is called abrasion corrosion. Also, in the case of a tank equipped with an open-to-atmosphere tank and a circulation pump which are not directly connected to a water supply, it is necessary to change the capacity of the circulation pump to a large one. Therefore, an object of the present invention is to provide an automatic hot-water supply bath apparatus capable of increasing the amount of pouring using both the outgoing pipe and the return pipe, and enabling split pouring while checking the water level.

湯し、追焚運転に移行させる。The automatic hot water supply bath apparatus according to the present invention performs the reheating operation after performing the pouring operation. In the pouring operation, in the initial setting operation, the water level and the hot water temperature in the bathtub are set by the control means, and then,
The air in the pipe is discharged to the outside, and the flow rate sensor disposed in the hot water supply pipe (branch pipe 11) starts measuring the flow rate of hot water. In this case, when the first conduit is opened, the hot water flows into the bathtub via the return pipe. Thus, the air in the return pipe is removed and filled with hot water, so that the water level in the bathtub can be accurately detected by the water level sensor. When the water level sensor detects that the water level rise value has reached the predetermined value, the control means stores the pouring amount at that time as the first pouring amount, and performs the pouring and the measurement of the pouring amount again. Let it start. When detecting that the set water level has been reached, the control means determines that pouring has been completed and stops pouring. The control means stores the pouring amount at that time as the second pouring amount, obtains the total pouring amount, and stores the pouring amount as a value corresponding to the set water level. Then, the control means starts the reheating operation based on the comparison between the set temperature and the current temperature. And when restarting, the control means is the same as the nostalgic driving,
Check the level of hot water in the bathtub, discharge the air in the pipeline to the outside, and start measuring the amount of hot water. At this time, the control means causes the pouring to be performed based on the stored first pouring amount. In other words, the control means controls the opening of the first conduit and the second conduit to perform pouring of the molten metal into the bath tub via the going pipe and the return pipe constituting the circulation path. When the stored first pouring amount is poured into the bathtub, the control means once stops pouring, checks the water level, starts pouring again, and stores the stored second pouring amount. The amount of hot water is poured into the bath, and the operation is shifted to the reheating operation.

The figure shows an embodiment of the automatic hot water supply bath apparatus of the present invention. Reference numeral 1 denotes an automatic hot water supply bath apparatus. The automatic hot water supply bath apparatus 1 includes a hot water supply heat exchanger 2, a bath heat exchanger 3,
A bath tub 5 is provided in communication with the bath heat exchanger 3 via a hot water circulation path 4. A water pipe 7 is connected to the water inlet 6 of the heat exchanger 2 for hot water supply. On the other hand, a hot water tap 10 for supplying hot water to the outside via a hot water supply pipe 9 is connected to the tapping side 8. A branch pipe 11 is connected to the hot water supply pipe 9 as a hot water supply side pipe.
11 includes a flow sensor 12 for detecting the flow rate of hot and cold water, a check valve 13 for preventing backflow, and a vacuum break valve 14 for adjusting the pressure in the branch pipe 11 when the forced circulation means described later is stopped. Intervening. A first pipe 15 and a second pipe 16 are branched and connected to the branch pipe 11, and the first pipe 15 is connected to the hot water introduction side 17 of the bath heat exchanger 3. It is connected to the tapping side 18 of the bath heat exchanger 3. Further, a water flow regulating valve 19, a two-way valve 20 as a first valve, a check valve 21
And a water amount regulating valve 22, a two-way valve 23 as a second valve, and a check valve 24. Further, on the tapping side 18 of the bath heat exchanger 3, a two-way valve 25 is provided as a third valve. The hot water introduction side 17 of the bath heat exchanger 3 is a return pipe for returning hot water to the bath heat exchanger 3 constituting the hot water circulation path 4.
The hot water outlet side 18 of the bath heat exchanger 3 is connected to an outgoing pipe 27 for supplying hot water to the bathtub 5 of the hot water circulation path 4. Note that the return pipe 26 and the outgoing pipe 27 are connected via a hot water circulation port 28 which is a hot water intake port formed in the bathtub 5. A water level sensor 29 for detecting the level of the hot water in the bathtub 5 and a circulation pump 30 as a forced circulation means for forcibly recirculating the hot water in the bath heat exchanger 3 are provided on the hot water introduction side 17. . A circulating water switch (not shown) that is turned on when hot and cold water flows through the circulation pump 30 is provided.
Is built-in. The automatic hot-water supply bath apparatus 1 is provided with a control unit 31 for receiving a detection signal and transmitting a control command relating to an operation with the above-mentioned constituent body. In the control unit 31, the level of hot water to be poured into the bathtub 5 by the remote control means 32 and the temperature of hot water are set. The operation will be described based on the above configuration. In the automatic hot water supply bath apparatus 1, after performing the pouring operation, the reheating operation is performed. (STEP 1) At the start of the operation, in the initial setting, the water level and the hot water temperature in the bathtub 5 are set in advance by the remote control means 32, and these setting information are taken into the control unit 31. According to the control output of the control unit 31, the two-way valve 20 and the two-way valve 23 are closed, the two-way valve 25 is opened, and the circulation pump 30 is operated. Check if. That is, a running water switch (not shown) incorporated in the circulation pump 30 detects whether hot water is turned on by flowing hot water through the circulation pump 30, and the hot water in the bathtub 5 is moved to the position of the hot water circulation port 28. You can check whether it is up to or not. (STEP 2) Only when a signal indicating OFF from the flowing water switch of the circulation pump 30 is input to the control unit 31, the control unit 31
It is determined that it is not up to the position of the hot water circulation port 28, and a control output based on the determination is obtained. As a result, the circulation pump 30 is stopped, the two-way valve 20 is opened, the two-way valve 28 and the two-way valve 25 are closed, hot water is introduced to discharge air in the pipeline to the outside, and the branch pipe 11 The measurement of the flow rate of hot and cold water is started by the flow rate sensor 12 disposed in the water heater. In this case, when the pipe 15 is opened, the hot water flows into the bathtub 5 via the return pipe 26. As a result, the air in the return pipe 26 is eliminated and filled with hot water, so that the water level in the bathtub 5 can be accurately detected by the water level sensor 29. In addition, the control unit
When a signal related to the initial pressure at the start of the air purge is input to the storage unit 31, the storage unit of the control unit 31 stores the signal related to the initial pressure as a measurement initial value of the water level. (STEP3) After storing this initial value, the control output of the control unit 31
The two-way valve 20 is closed, the two-way valve 23 is opened, the two-way valve 25 is closed, and the bath 5 is poured. Then, a change value from the measurement initial value of the water level with respect to the signal related to the initial pressure by the water level sensor, that is, a detection output in which the rising value of the water level from the circulation port 28 is 5 cm is the water level sensor 29.
Is input to the control unit 31 from the controller, the control unit 31 closes the two-way valve 23 and stops pouring. (STEP 4) At this time, by the control output of the control unit 31, the two-way valve 25 is opened to operate the circulation pump 30, and the running water switch (not shown) built in the circulation pump 30 is turned on, so that the water level is increased. Is determined to have reached a predetermined water level (5 cm) above the hot water circulation port 28, and the pouring volume up to that point is determined by the first
It is stored in the storage means of the control unit 31 as the second pouring amount (Q 1 ). (STEP 5) Next, according to the control output of the control unit 31, the two-way valve 23 is opened, the two-way valve 25 is closed, and pouring is performed again.
31 takes in the signal from the flow rate sensor 12 and the measurement of the pouring amount is started. When the water level sensor 29 detects that the set water level has been reached, pouring is completed. That is, the two-way valve 23 is controlled by the control output of the control unit 31 based on the detection output of the water level sensor 29.
Close to stop pouring. The control unit 31 calculates the amount of pouring water after the first pouring amount (Q 1 ) by adding the signal from the flow rate sensor 12 to the second
It is taken in as the second pouring amount (Q 2 ) and stored in the storage means. At the same time, in the control unit 31, the total pouring amount (Q = Q 1 +
Q 2 ) is obtained, and the total pouring amount Q is stored as a value corresponding to the set water level. Then, the control unit 31 controls the reheating operation based on the comparison between the current temperature and the set temperature so that the hot and cold water temperature in the bathtub 5 reaches the set temperature. (STEP 6) Next, the operation at the time of driving again will be described. The control unit 31
Check the level of hot water in the bathtub 5 and start measuring the amount of hot water in the operating procedure of STEPs 1-2. When an ON signal is input to the control unit 31 from the flowing water switch of the circulation pump 30, the control unit 31
Determines that the hot water in the bathtub 5 has reached the position of the hot water circulation port 28, opens the two-way valve 23, closes the two-way valve 20 and the two-way valve 25, and performs pouring until the set water level is reached. When the OFF signal from the water switch is input to the control unit 31, first, by the control output of the control unit 31, the air is discharged by pouring, the measurement of the pouring amount is started, and from the water level of the circulation port 28, Performs the pouring of the first pouring amount (Q 1 ) stored above. In this case, the pipeline 15 and the pipeline 16 are opened from the control output of the control unit 31, that is, the two-way valve 20 and the two-way valve 23 are opened, the two-way valve 25 is closed, and the hot water circulation path 4 is opened. The bath is poured into the bathtub 5 via the outgoing pipe 27 and the return pipe 26 which are configured. (STEP 7) Then, the first pouring of the pouring amount (Q 1 ) is performed, and once the pouring and the measuring of the pouring amount by the flow rate sensor 12 are stopped, the water level rise value is 5 cm above the hot water circulation port 28. Is confirmed by the detection output of the water level sensor 29, the pouring and the measurement of the pouring amount by the flow rate sensor 12 are started again, and the pouring by the stored second pouring amount (Q 2 ) is started. Done. After pouring the second pouring amount (Q 2 ), it is confirmed by the detection output of the water level sensor 29 that the set water level has been reached.
The control unit 31 performs additional heating operation control. Thus, the total pouring amount (Q = Q 1 +
Q 2 ) is divided into two parts, and the pouring is performed while checking the water level. Therefore, it is possible to reach the set water level without overflowing without being affected by the remaining hot water in the bathtub 5. .

での注湯を迅速化できる。As described above, according to the present invention, the following effects can be obtained. a. Since both the forward pipe and the return pipe that make up the circulation path are used for pouring into the bathtub, the pouring volume should be increased by reducing the pressure loss compared to when pouring with only one pipe. Thus, a predetermined amount of molten metal can be poured in a short time. b. The flow resistance of the hot water can be reduced by using both the forward pipe and the return pipe forming the circulation path, so that the so-called erosion phenomenon can be suppressed, and the hot water supply capacity is large due to the increase in the pouring volume. The performance can be exhibited using heat exchange air for use. c. Even if water is supplied from a water supply source with low water pressure, it is possible to respond without reducing the pouring amount so much, and divide the total pouring amount registered during the first operation until the set water level is reached while checking the water level. Since the hot water is poured, the hot water can be quickly poured to the set water level of the bath tub without being affected by the remaining hot water in the bath tub and without overflowing.
