Abstract

PURPOSE:To eliminate wasteful use of hot-water by constructing a title device such that even through an operation signal is sent to operating means a plurality of times using communication means, hot-water is supplied to a bath tank only at a first signal. CONSTITUTION:Once an operation signal is sent from a telephone set 70 through a telephone network 71, a water changeover valve 58 is turned on to produce a water flow in a water piping 50. A water amount detection sensor 53 detects a water flow to start burning. The amount of the burning of a fuel is determined on the basis of the amount of the water, influent water temperature, etc., detected by various sensors, such that hot-water at preset temperature is supplied into the bath tank 60. Herein, even though a plurality of persons fill the tank with water by remote operation or an operation signal is sent to a control circuit 20 a plurality of times through the telephone line network 71, the tank is filled with water only at a time a first operation signal is received. Accordingly, wasteful use of hot-water is eliminated because no water filling is performed a plurality of times. Further, even though the operation signal is sent plurality of times, hot-water is prevented from overflowing the bath tank 60 because only once hot-water supply is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote device for a bath water heater that supplies hot water to a bathtub from a remote location using a communication means such as a telephone. [Prior Art] In recent years, with the development of home automation, a remote device for a bath water heater has been devised that supplies hot water to a home bathtub from a remote location using a telephone.

This remote device for bath water heaters is designed so that when an operating signal is sent from a remote location using a telephone, the operating means connected to the four-wire telephone receives the operating signal, and a set amount of hot water is supplied to the bathtub by the hot water supply means. It supplies hot water to the [Problem to be Solved by the Invention 1] However, the conventional remote device of the bath water heater supplies hot water at setting 1 to the bathtub every time it receives an operation signal. That is, for example, when a person sends an operation signal using a telephone, a set amount of hot water (for example, 200 liters) is supplied to the bathtub. After that, when another person generates an operation signal using a telephone, 200 liters of hot water is newly supplied to the bathtub. As a result, hot water overflowed from the bathtub without an overflow, and 200 liters of hot water was wasted. The present invention has been made in view of the above circumstances, and its object is to supply hot water to the bathtub only once, even if an operation signal is sent to the operation means multiple times through the communication means. The purpose is to provide a remote device for the device. [Means for Solving the Problems] In order to achieve the above object, the remote device for a bath water heater of the present invention has a hot water supply means 2 for supplying hot water to a bath basin 1 and , an operation step 4 for supplying a set amount of hot water to the bathtub 1 by the hot water supply step 2 upon receiving an operation signal through the communication step 3 such as a telephone, The means 4 includes at least a memory means 5 for storing, when hot water is supplied to the bathtub 1 using the communication means 3, 1) a message indicating that hot water was supplied to the bathtub; a resetting means 6 for resetting the fact that hot water has been supplied to the bathtub; and a determining means 7 for determining whether or not the storage means 5 has stored the fact that hot water has been supplied to the bathtub when receiving an operation signal; , when it is determined by the judgment step 7 that the storage means 5 does not remember the fact that hot water has been supplied to one bathtub, the hot water supply means 2 is made to supply a set amount of hot water to the bathtub 1; Technical means include means 8. [Operation] A rubbing signal is transmitted to the operating means of the remote device of the bath water heater which has been heated as described above through the communication means. Then, the determining means of the operating means determines whether or not "the fact that hot water was supplied to the bathtub" is stored in the storage means. If the storage means does not store the fact that "hot water was supplied to the bathtub", the execution means causes the hot water supply means to supply a set amount of hot water to the bathtub, and the storage means stores 1" that hot water was supplied to the bathtub. 1. On the other hand, when an operation signal is sent to the drying means through the communication means and the storage means stores "hot water was supplied to the bathtub", the execution means stores hot water in the bathtub. Not supplied.

Note that the reset means is for resetting ``hot water was supplied to the bathtub'' stored in the storage means 1 manually or when a predetermined condition is satisfied. By resetting the message "that has been performed," hot water can be supplied to the bathtub using an operation signal.

[Effects of the Invention] Since the present invention has been accomplished as explained above,
This produces the effects described below.

Even if an operation signal is sent to the harvesting means multiple times using the communication means, hot water can be supplied to the bathtub only the first time.
As a result, unnecessary consumption of hot water can be eliminated. Further, even if the operation signal is sent to the operation means multiple times, hot water is supplied only once, so hot water is prevented from overflowing from the bathtub even in a bathtub without an overflow. [Example] Next, a remote device for a bath water heater of the present invention will be explained based on an example shown in the figure. Figures 2 to 5 show a first embodiment of the present invention. Figure 2 shows a schematic diagram of the gas water heater for baths. This gas water heater for a bath is broadly divided into a thousand hot water supply stages 10 and a control circuit 20 for operating the hot water supply means 10. The hot water supply means 10 also includes a combustion section 30, a gas supply pipe 40, and a water pipe 50. The combustion part 30 includes a combustion case 32 made of pressed stainless steel plates and having stacked burners 31 arranged therein;
It consists of a blower 33 that supplies combustion air into the combustion case 32. After combustion, the air introduced into the combustion case 32 by the blower 33 is discharged from the exhaust port 34 as combustion gas. In the vicinity of the burner 31, there are a sparker 35 for igniting gas, a flame rod 36 for detecting flame, and a thermocouple 3 for detecting the air-fuel ratio.
1 is attached. The blower 33 also includes an air volume detection sensor 38 (a third
(see figure) is attached. The gas supply pipe 40 supplies fuel gas to nozzles 41 formed corresponding to each opening of the burner 31, and is provided with a main solenoid valve 42, a main solenoid valve 43, and a proportional valve 44 in this order from upstream. There is. Further, the gas supply pipe 40 downstream of the proportional valve 44 is provided so as to be branched into two, and a switching solenoid valve 45 is provided on one of the branches. Original solenoid valve 42,
The main solenoid valve 43 and the switching solenoid valve 45 open the gas supply pipe 40 when energized, and open the gas supply pipe 40 when the energization is stopped. Further, the proportional valve 44 has an aperture ratio that changes depending on the amount of energization, and adjusts the amount of gas supplied to each nozzle 41.

The water pipe 50 has one end connected to a water supply source and the other end connected to a hot water supply port, and exchanges heat generated by combustion of gas in the combustion case 32 with water flowing inside. A heat exchanger 51 is provided. Upstream of the heat exchanger 51, there is an electric water control device W152 that controls the amount of water flowing into the heat exchanger 51 according to the amount of electricity, and a water amount detection sensor 53 that detects the amount of water flowing into the heat exchanger 51. An inlet water temperature sensor 54 is provided to detect the temperature of water flowing into the heat exchanger 51.

Furthermore, a hot water outlet temperature sensor 55 is provided in the water pipe 50 downstream of the heat exchanger 51 to detect the temperature of the hot water that has passed through the heat exchanger 51. Thousand-flow water pipe 50 of outlet hot water temperature sensor 55
is divided into two parts. One of the branched pipes is a bath pipe 56, which is connected to a hot water inlet on the side wall of the bathtub 60.
The other branched pipe is a hot water supply pipe 57, which is connected to a hot water supply port other than the hot water supply port of the bathtub 60. The bath piping 56 is provided with a water switching valve 58. This water switching valve 58 opens the waterway when energized and closes the waterway when the energization is stopped. Further, the hot water supply pipe 57 is provided with a water flow switch 59. This water flow switch 59 is turned on by the generated water flow when the switch connected to the hot water supply pipe 57 is opened. Next, the control circuit 20 will be explained. The control circuit 20 is an operating means of the present invention for operating the hot water supply means 10, and as shown in FIG.
1. Consists of a relay circuit 22 and a drive circuit 23,
Each of the above-mentioned driving means is activated according to the outputs of the controller 24 and various sensors (frame rod 36, thermocouple 37, air volume detection sensor 38, water volume detection sensor 53, inlet water temperature sensor 54, hot water outlet temperature sensor 55, water flow switch 59). (Blower 41l33, Suba force 35, Original solenoid valve 42
, the main solenoid valve 43, the proportional valve 44, the switching solenoid valve 45, the electric water flow control device 52, and the water switching valve 58). Note that numerals 25 and 26 shown in the figure are potentiometers that detect the opening degrees of the electric water flow control device 52 and the water switching valve 58, respectively. Further, the control circuit 20
As shown in the figure, it is equipped with an HA terminal (home automation terminal) 27. I get it. When this I-IA terminal 27 receives an operation signal from a telephone 70, which is a communication means, via a telephone line II 471, the distributor 7 generates an HA signal.
It is connected to 2. The microcomputer 21 of the control circuit 20 then
}The remote control means 80 is programmed to supply a set amount of hot water to the bathtub 60 when the IA terminal 27 receives the HA signal. Note that this remote control 1000 steps 80 functions as a storage means, judgment means, and execution means of the present invention. The operation of the remote control means 80 will be explained based on the flowchart 1 in FIG. In step S1, it is determined whether or not a manipulation signal has been received. If the result of this judgment is No (the operation signal has not been received), the process returns to step S1.Also, if the judgment result of step S1 is Yes (the operation signal has been received from the telephone 70 via the telephone line network 71), the process returns to step S1. If so, in step S2, it is determined whether or not the flag is set (1) (determination means of the present invention), which has the same meaning as "hot water has been supplied to the bathtub" of the present invention. This determination result If NO (the flag is not set), a flag is set in step S3 (storage means of the present invention).In other words, this means that the microcomputer 21 stores the fact that "hot water was supplied to the bathtub". Subsequently, in step S4, the hot water supply means 1 is operated so that a set amount of hot water (Ji according to the bathtub) is supplied to the bathtub 60.
0 (execution means of the present invention). If the judgment result in step S2 is yrs (the flag is set),
It is determined that the bathtub 60 is already filled with hot water and returns. In other words, hot water is not supplied to the bathtub 60. In addition, the remote control means 80 lowers a flag (resets "hot water was supplied to the bathtub") reset means 81
Equipped with The operation of this reset means 81 will be explained based on the flowchart shown in FIG. In step 311, it is determined whether the reset switch (not shown) provided on the controller 1/roller 24 has been turned on by the user.The result of this determination is YES.
If (the reset switch has been operated), the flag is lowered in step S12. In other words, ``Reset the fact that hot water has been supplied to the bathtub.'' If the result of judgment IIri in step S11 is No (the reset switch has not been operated), in step S13, it is determined whether or not the water flow switch 59 has been turned on. If the result of this determination is YES (water flow switch 59 is turned on), the process advances to step S12 and the flag is lowered.Also, the determination result of step S13 is No (water flow switch 59 is not turned on). If so, return.Next, the operation of the hot water supply means 10 that supplies a set amount of hot water to the bathtub 60 by the operation of the remote control means 80 will be briefly explained.As mentioned above, when the flag is not set, , when an operation signal is sent from the telephone 70 via the telephone line l1371, the water switching valve 58 is turned on and a water flow is generated in the water pipe 50.Then, the water flow detection sensor 53 detects the water flow, and combustion starts. The amount of fuel burned is determined from the amount of water, inlet water temperature, outlet temperature, etc. obtained by various sensors so that hot water at a preset temperature is supplied to the bathtub 60. When started, the water amount detection sensor 53 measures the amount of water supplied to the heat exchanger 51, that is, the amount of hot water supplied to the bathtub 60. Then, the amount of hot water supplied to the bathtub 60 is determined. When the set amount is reached, the water switching valve 58 is turned off. When the water switching valve 58 is turned off, the flow of water in the water pipe 50 stops.Then, the water flow detection sensor 53 stops detecting the water flow, and combustion stops. As shown in the above embodiment, even if a plurality of people fill the water by remote control, that is, even if an operation signal is sent to the control circuit 20 multiple times via the telephone line network 71, The hot water is filled only when the first operation signal is received.As a result, it is possible to eliminate the unnecessary consumption of hot water by not filling the hot water multiple times as in the past. Even if hot water is sent back, hot water is supplied only once, so even in a bathtub 60 without overflow, hot water is prevented from overflowing into the bath ram 60. Note that while hot water is being supplied to the bathtub 60, it is connected to the hot water supply piping 57. When the door is opened, the water flow switch 59 is turned on by the water flow generated in the hot water supply piping 57.Then, while the water flow switch 59 is turned on, the water switching valve 58 is turned off.
It will be done. As a result, hot water supply to each tank is given priority over hot water supply to the bathtub 60. Further, even if the user does not manually operate the reset switch of the controller 24, the flag is lowered when the switch connected to the hot water supply pipe 57 is opened.

Therefore, even if the user forgets to operate the manual reset switch when the flag is lowered by simply supplying hot water from the tap when he/she is at home and returns home, the bathtub 60 can be filled with hot water using the telephone 10 next time. FIG. 6 shows a second embodiment of the present invention with 10 stages of hot water supply. Note that the same reference numerals as in the above embodiments indicate the same functional objects. In this embodiment, the hot water in the bathtub 60 is configured to be circulated by a circulating water pipe 91 and a pump 92, and this circulating water pipe 91 is provided with a heat exchanger 93 for reheating. Further, the circulating water pipe 91 is connected to the downstream side of the heat exchanger 51 via a three-way switching valve 94. This three-way switching valve 9
4, it is possible to switch between the operation of supplying hot water heated by the heat exchanger 51 to the bathtub 60 and the operation of supplying hot water heated by the heat exchanger 93 to the bathtub 60. In the figure, reference numeral 95 is an electromagnetic on-off valve, and reference numeral 96 is a hopper. These pumps 92 and each open valve 95
The power supply is controlled by various sensors and a control circuit (not shown). A third embodiment of the present invention is shown in FIGS. 7 to 11. Figure 7 shows a schematic block diagram of the gas bath water heater in this embodiment. In this embodiment, when a hot water filling signal is sent from a remote telephone 70, the bathtub 60 is automatically filled with hot water, and when a hot water filling stop signal is sent, the automatic filling of hot water is stopped. and,
A telephone controller 28 (hereinafter referred to as a telephone controller) is connected to the controller 24 of this embodiment. The teleconverter 28 constantly receives a monitor signal from the controller 24 for determining the operating state of the wooden body 11. Then, when the main unit 11 is not operating and the teleconverter 28 receives a hot water filling signal via the telephone line 1il71 and the distributor 72, the teleconverter 28 transmits a teleconverter ON signal to the controller 24. In addition, the teleconverter 28 has a main body 11 in operation, a telephone line of $11,771,
When a hot water filling stop signal is received via the distributor 72,
Sends the teleconverter F signal to controller 17-ra 24. The controller 24 includes a display section that displays the operating status of the bath gas water heater to the user, and a plurality of operation switches for filling hot water, setting the hot water temperature, and the like. Further, the controller 24 includes a control circuit 24a that transmits an instruction signal for operating the bath gas water heater in accordance with the operating state of the operation switch. This control circuit 24a includes a microcomputer 24b. When this microcomputer 24b receives the teleconverter ON signal from the teleconverter 28, it judges the past hot water filling situation, transmits the teleconverter ON signal to the control circuit 20 of the main body 11, and sends the teleconverter ON signal from the teleconverter 28 to the control circuit 20 of the main body 11.
A hot water filling instruction function is programmed to transmit a teleconverter OF°F signal to the control circuit 20 of the main body 11 when the FF signal is received. In addition, the microcomputer 20a of the control circuit 20 of the main body 11 of this embodiment has a hot water supply controller that controls the filling of hot water into the bathtub 60 according to the teleconverter ON signal or the teleconverter Or} signal transmitted from the controller roller 24. A tension control function is programmed. Next, an example of the hot water filling instruction function programmed into the controller 1/roller 24 will be explained based on the flowchart shown in FIG. When the operation is stopped, the operation display is turned on in step S21. Next, in step S22, the hot water filling display is turned off. Subsequently, in step S23, the teleconference flag is turned off.

In step S24, from the teleconverter 28 to the teleconverter O
It is determined whether or not the N signal has been received. Step S24
If the determination result is NO, the process returns to step S24. Further, if the determination result in step S24 is YrS, it is determined in step S25 whether or not the teleconference flag is set. If the determination result in step S25 is YES, the process returns to step S24.

Further, if the determination result in step S25 is NO,
In step 326, the operation display is ONL, and in step S
At step 27, turn on the hot water filling display. Subsequently, in step 328, a teleconverter ON signal is transmitted to the control circuit 20 of the main body 11. In step S29, from the teleconverter 28 to the teleconverter O
Determine whether the FF signal has been received or not. Step S2
If the determination result in step 9 is NO, it is determined in step S30 whether or not a boiling ON signal has been received from the control circuit 20 of the main body 11. If the determination result in step S30 is NO, the process returns to step S29. Further, if the determination result in step 830 is YES, step S31
Set up a teleconference flag. In step S32, the hot water is displayed, and in step S33, steam is displayed for 30 seconds, and then the process returns to step S24.

In addition, if the determination result in step S29 is Y[S, the driving display is enabled in step S34, and in step S3
At 5, set the hot water filling display to 0[F. Then, in step S36, a teleconverter OFF signal is transmitted to the control circuit 20 of the main body 11, and then the process returns to step S24. In addition, the microcomputer 24b of the controller 24
is programmed with a teleconverter reset function that lowers the teleconverter flag. An example of this teleconverter reset function will be explained based on the flowchart in Figure 9. First, in step S41, it is determined whether any switch of the controller 24 has been operated. If the determination result in step S41 is YES, step S41
At 42, a counter reset signal is sent to the control circuit 20 of the main body 11. Subsequently, in step S43, the teleconference flag is lowered, and then the process returns. If the determination result in step S41 is NO, in step S44, from the control circuit 20 of the main body 11,
Determine whether or not the call ON signal has been received. If the determination result in step S44 is YES, step S43
Proceed to. Furthermore, if the determination result in step S411 is NO, the process returns. Next, an example of the hot water filling control function programmed into the control circuit 20 of the main body 11 will be explained based on the flowchart shown in FIG. First, in step S51, the operation is turned off.
In step S52, the hot water is filled.
In step S53, a counter for measuring the amount of hot water filled is set to an initial value. In step S54, it is determined whether a teleconverter ON signal from the controller 24 has been received. If the determination result in step S54 is NO, the process returns to step S54. Further, if the determination result in step S54 is YES, combustion operation is started in step S55, and automatic hot water filling is started in step 356. In step S57, it is determined whether a teleconverter OFF signal from the controller 24 has been received. If the determination result in step S57 is NO, it is determined in step 358 whether the counter value has reached the set amount. If the determination result in step 358 is NO, the process returns to step S57. If the determination result in step 858 is YES, automatic hot water filling is stopped in step S59. Subsequently, in step S60,
A boiling ON signal is sent to the controller 24. Subsequently, in step S61, automatic heat retention is performed to maintain the hot water in the bathtub 60 at a constant temperature. Thereafter, the process returns to step S54. If the determination result in step S57 is YES, the combustion operation is stopped in step S62, and the combustion operation is stopped in step S62.
3, the automatic hot water filling operation is stopped, followed by storing the counter value in step S64, and then returning to step S354. Note that the automatic heat retention function is to stop the operation by operating the operation switch of the controller 24 or after 4 hours. Further, the microcomputer 20a of the control circuit 20 of the main body 11 is programmed with a hot water filling amount reset function for resetting the stored counter value after the automatic hot water filling operation is completed. An example of this hot water filling reset function will be explained based on the flowchart of FIG. 11.

First, in step S71, the water flow switch is turned on.
Determine whether or not the If the determination result in step S71 is YES, a click ON signal is transmitted to the controller 24 in step S72. Step 3
At step 73, the counter value is reset to 1. If the determination result in step S71 is NO, it is determined in step S74 whether or not a counter reset I- signal has been received from the controller 24. If the determination result in step S74 is YES, step S73
Proceed to. Further, if the determination result in step S74 is NO, the process returns. Next, the above operation will be briefly explained. In this embodiment, as shown above, when the main body 11 is not operating or the teleconverter flag is lowered, and the user sends a hot water filling signal to the teleconverter 28, the main body 11 is activated. Start automatic hot water filling operation. When the automatic hot water filling operation starts and a set amount of hot water is poured into the bathtub 60, the automatic hot water filling operation ends. Then, when the water boils, the telecon flag will go up, so the user can send the water filling signal to the telecon 2.
Even if you send the message to 8, automatic hot water filling operation will not be performed. On the other hand, when the user sends a hot water filling stop signal to the teleconverter 28 during the automatic hot water filling operation, the main body 11 stops the automatic hot water filling operation and stores the counter value. When the user sends a hot water filling signal to the teleconverter 28 again, the main body 11 resumes automatic hot water filling operation. At this time, since the control circuit 20 of the main body 11 stores the past counter value, the set amount of hot water can be poured into the bathtub Go. Therefore, hot water does not overflow from the bathtub 60, which has no overflow. (Modification) Although an example is shown in which a gas water heater is used as the hot water supply means, a water heater that uses other fuels such as kerosene or an electric water heater that uses electricity may also be applied.

Further, the present invention may be applied to a hot water supply means that stores hot water and then supplies the stored hot water, such as a hot water storage type electric hot water heater. Furthermore, although an example is shown in which a telephone line is used as the communication means, any communication means such as a communication means using commercial electric wires or wireless communication may be used.
