Abstract

PROBLEM TO BE SOLVED: To solve the difficulty with prior art that when warm water supply from a hot water supplier is received to use a warm water application apparatus, set temperature of the hot water supplier must be adjusted every time it is used in compliance with the object of the application, while when a plurality of such warm water application apparatuses are used simultaneously, warm water in compliance with the object of the application is impossible to be supplied. SOLUTION: Operation data such as set temperatures and water amount data of a hot water supplier and a warm water application apparatus are delivered. The hot water supplier decides single use of the warm water application apparatus or simultaneous use with another apparatus on the basis of received water amount data of the warm water application apparatus and water amount data of itself. If the single use is decided, then the set temperature of the hot water supplier is altered to the set temperature of the warm water application apparatus. The warm water application apparatus stops the supply of warm water when it receives data indicative of the simultaneous use with another apparatus from the hot water supplier.

BEST MODE FOR CARRYING OUT THE INVENTION In order to better understand the contents of the present invention, detailed description will be given below with reference to embodiments.

[0009]

FIG. 1 is a block diagram showing an embodiment of the present invention. The water heater (1) comprises a hot water supply amount detecting means (2) for measuring the amount of hot water supplied from the water heater (1) and a water heater control means (6) for controlling the water heater (1). ing. On the other hand, the hot water use device (11) connected to the hot water supply device (1) through the hot water supply passage (21) includes a hot water usage amount detection means (12) for measuring the amount of hot water supplied from the hot water supply device. There is. Further, the water heater (1) has a water heater communication means (3) and the hot water equipment (11) has a hot water equipment communication means (13), each of which is connected by a communication path (22) and includes water volume information. They are sending and receiving driving information to and from each other.

Next, this hot water supply system will be described. When the use of the hot water using device (11) is started, hot water starts to flow from the hot water supply device (1) through the hot water supply passage (21) to the hot water using device (11). At this time, the hot water supply amount detecting means (2) detects the amount of hot water supplied by the hot water supply device (1). On the other hand, the hot water use amount detection means (12) detects the amount of hot water used by the hot water use device (11). The hot water use device control means (16) transmits the detected hot water use amount to the hot water supply device communication means (3) via the communication path (22) using the hot water use device communication means (13). The hot water heater control means (6) compares the hot water supply amount detected by the hot water supply amount detection means (2) with the hot water use amount transmitted from the hot water use device, thereby performing various controls considering user's usability. It becomes possible to

When it is determined that the hot water supply amount detected by the hot water supply amount detecting means (2) is larger than the hot water use amount transmitted from the hot water use device (11), the hot water supply device (1) supplies the hot water. Since it is considered that the hot water is used in addition to the hot water using device (11), the hot water supply control means (6) uses the hot water supply communication means (3) and the hot water using device via the communication path (22). It transmits to the communication means (13) that it is not used alone. The main body (11) of the device using hot water that has received the notification can know that the water heater (1) is not the only one using the device itself. Therefore, for example, the fact is notified and the user is alerted. It becomes possible.

FIG. 2 shows another embodiment in which a water stopping means (14) is added to the hot water equipment (11). When the hot water using device (11) receives a signal indicating that it is not used alone, the water stopping means (14) is activated to stop the supply of hot water. Alternatively, the water stop means (14) may be operated to stop the supply of the hot water only when it is determined that the temperature or amount of the hot water capable of sufficiently exerting the capability of the hot water using device (11) cannot be used. By doing so, it is possible to prevent wasteful hot water consumption and burns due to high-temperature water that the user does not intend, when the ability of the hot water using device (11) cannot be fully exerted.

In FIG. 3, hot water supply temperature setting means (5) is added to the water heater (1) and hot water use temperature setting means (11) for setting the temperature desired to be used by the hot water use equipment (11) ( 15) is another embodiment in which and are added. The hot water use device (11) transmits the hot water use temperature set by the hot water use temperature setting means (15) to the water heater control means (6) in the same manner as described above, in addition to the hot water use amount. When the hot water supply control means (6) determines that the hot water supply amount detected by the hot water supply amount detection means (2) and the hot water use amount transmitted from the hot water use device (11) are equal, the hot water supply device (1 Since it is considered that the hot water supplied from () is only the hot water using device (11), the water heater control means (6) determines that the temperature of the hot water supplied from the water heater (1) is the hot water using device (11). The control is performed so that the hot water use temperature transmitted from is reached. Then, the user of the hot water using device (11) does not operate the hot water supply temperature setting means (5) arranged in the hot water supply device (1), and the hot water temperature can sufficiently exhibit the performance of the hot water using device (11). Can be used in.

FIG. 4 is a flowchart summarizing the above operation. First, the processing on the side of the water heater will be described. First,
The data transmitted from the hot water using device (11) is received (a), and the detected value is calculated based on the signal from the hot water supply amount detecting means (b). Next, the calculated detection value and the received hot water usage amount are compared (c), and the operation information of the water heater (1) including the comparison result is transmitted to the hot water using device (11).
Further, when the result of the comparison determines that the hot water supply amount and the hot water usage amount are equal, the water heater control means (6) is controlled so that the hot water having the received hot water usage temperature can be supplied (f).

On the other hand, the processing on the equipment side using hot water first receives the data transmitted from the water heater (1) (v), and when the comparison result that the hot water supply amount is larger than the hot water usage amount is received. The water stopping means (14) is activated to stop (x) the supply of hot water, and the operation of the equipment using hot water is temporarily stopped. next,
A detection value is calculated based on the signal from the hot water usage detecting means (y), and the calculation result and the hot water usage temperature are transmitted to the water heater (1) (z).

With the above operation, the hot water supply system can be used without troublesome operation and can avoid the risk of being able to use the hot water using device in a state where the performance of the hot water using device can be fully exerted and accidentally burned. Can be built.

The communication path (22) may be wireless.
