When the time specified by the relative time data has been reached, the set time is used as the set time to control the operation, stop, or setting of the device. Lies in that is constituted by a cement response control means.
[0008]
That is, the event correspondence control means is configured to control the operation or stop or the setting of the device when the time specified by the relative time data with respect to the event occurrence time data input by the event information input means is set as the set time. Once the event information has been entered, the subsequent change operation can be updated by updating only the reference event occurrence time data, eliminating the need for complicated operations to set and input different operation times and the like. It becomes.
[0009]
For example, as a hot water terminal, for a plurality of hot water floor heaters or hot water panel heaters installed in a plurality of rooms, assuming a scheduled wake-up time in the morning as the event occurrence time, a first predetermined time before the scheduled wake-up time Activating the bedroom hot water panel heater, operating the living room hot water floor heater at the second predetermined time before the scheduled wake-up time, and activating the kitchen hot water panel heater at the third predetermined time before the scheduled wake-up time, The operation of the device can be efficiently controlled in accordance with the life pattern after getting up, and the above-described first to third predetermined times correspond to relative time data.
[0010]
If it is necessary to change the operation time of each device in accordance with the change of the scheduled wake-up time, the change of the event wake-up time, which is the scheduled wake-up time, can be used as a reference. Control of various devices is started at the relative time.

In the point that it is configured with a communication means capable of receiving, for example, with the change of the wake-up time, even when it is necessary to set or change the event occurrence time, without having to individually perform the setting change operation In addition, the setting can be automatically changed by the communication means, and the complexity of the operation is eliminated.
[0016]
The fifth characteristic configuration is, as described in claim 5 in the same column, in addition to the characteristic configuration described in any one of the above-described first to fourth configurations, the timer control means is different from the hot water terminal. The configuration is such that the operation, stop or setting of the devices can be controlled.

[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the hot water supply / room heating system includes a heat source device 1, a plurality of hot water terminals 2 connected to the heat source device 1, and individually operating, stopping, or setting control of each hot water terminal 2 at a set time. And a timer control means 3 for performing the operation.
[0018]
The heat source unit 1 includes a first gas burner 1c, a first heat exchanger 1d that heats water supplied from a water supply pipe 1a to a predetermined temperature and supplies the water to a hot water supply pipe 1b, and a second gas burner 1e. And a second heat exchanger 1g for heating water circulating in the pipe 1f to a predetermined temperature, and operating the heat exchangers 1d and 1g based on the input of an operation state signal described later, and a circulating pump described later. Heat source device control means 1i for performing operation control for 1h is provided.
[0019]
The hot water terminal 2 is specifically composed of a hot water panel heater, a floor heater, a bathroom dryer, and the like. The circulation pipe 1f is branched, and a branch pipe 2a installed in each installation section is provided. A valve mechanism 2b for controlling the supply of hot water to each branch pipe 2a from a circulation pump 1h that circulates hot water into the supply pipe 1f and the branch pipe 2a, and a terminal for adjusting the opening / closing or opening of the valve mechanism 2b. It is provided with control means 2c. The terminal control means 2 c is operated by a start / stop switch (not shown) and a temperature setting switch (not shown) for manually controlling the operation of the hot water terminal 2, or by operation of the timer control means 3. In addition to opening and closing (corresponding to start and stop) or opening (corresponding to temperature setting) of the valve mechanism 2b, the valve mechanism 2b outputs an operation state signal indicating operation, stop, set temperature and the like to the heat source unit 1.
[0020]
The timer control means 3 also has a function as a remote control means capable of controlling the operation of the plurality of hot water terminals 2 individually. As shown in FIG. 2, the timer control means 3a, the event occurrence time data and the event occurrence time Event information input means 3b for inputting relative time data with respect to data, event information including device ID data for specifying the hot water terminal 2 as a control target of operation or stop or setting, and time measured by the time measurement means 3a When the time specified by the relative time data with respect to the event occurrence time data input by the event information input means 3b is reached, the operation of the hot water terminal 2 specified by the device ID data is set as the set time. Or start, stop, set temperature to the terminal control means 2c in order to control stop or set. And an input switch unit 3e for remote control, and a touch panel type display capable of displaying the current time measured by the timer unit 3a and the input state of the event information input unit 3b. It comprises a display means 3d, a memory means (not shown) for storing event information, and the like.
[0021]
As shown in FIG. 3, the event information includes event ID data as event type data, event name data, event occurrence time data associated with the event type data, and the hot water terminal 2 to be controlled. The terminal ID data, the relative time data with respect to the terminal specified by the terminal ID data, and the operation type data for specifying each operation type of operation, stop, and setting of the hot water terminal 2. Input by means 3b.
[0022]
A procedure for inputting event information by the event information input means 3b will be described. As shown in FIG. 4, when the event information input switch (mode switch) 31 set on the touch panel of the display unit 3d is turned on, the mode is switched to the event information input mode. In the event information input mode, a current date and time, a time display column 32, an event type display column 33, an event occurrence time display column 34, a terminal ID display column 35, an operation type column 39, a set switch 36, and setting switches 37 and 38 are displayed. Is done. When the mode is switched to the event information input mode, the frame of the event type display field 33 blinks, and each time the upper and lower setting switches 37 and 38 are turned on, candidate event names (wake-up, attendance, returning home, bathing, etc.) Is displayed, the event ID data corresponding to the display content when the set switch 36 is turned on is determined, and the frame of the event occurrence time display section 34 blinks. In this state, each time the upper and lower setting switches 37 and 38 are turned on, the candidate time data is updated and displayed at one-hour intervals, so that the set switch 36 is turned on at the time the corresponding time data is displayed. Time data is determined, and similarly, every time the upper and lower setting switches 37 and 38 are turned on, candidate minute data is updated and displayed at one-minute intervals, so that the corresponding minute data is displayed. , The minute data when the set switch 36 is turned on is determined, then the frame of the terminal ID display column 35 blinks, and each time the upper and lower setting switches 37 and 38 are turned on, the terminal ID which becomes a candidate is displayed. (It may be an easily recognizable symbol or the like.), The terminal ID corresponding to the display content when the set switch 36 is turned on is determined, and the operation type is set in the same procedure. When the set switch 36 is further turned on in this state, the mode is shifted to the reset mode of the event type display field, and the same operation is repeated thereafter. When the data is set correctly and the mode switch 17a is turned on, the setting ends. It is not necessary to input event occurrence time data for the same event ID data, and all are rewritten with the latest input value.
[0023]
The event correspondence control means 3c sets the operation of the hot water terminal 2 when the time specified by the relative time data with respect to the event occurrence time data is reached for any event ID data among the set event information. The control information is output to the terminal control means 2c to control the operation, stop, or setting of the hot water terminal 2 specified by the terminal ID data as the time.
[0024]
The terminal control means 2c receives the control signal from the event response control means 3c and controls the opening and closing (corresponding to start and stop) or the opening degree (corresponding to temperature setting) of the valve mechanism 2b. An operation state signal indicating operation, stop, set temperature and the like is output to the heat source unit 1. The heat source device control means 1i of the heat source device 1 receives the operation state signal, ignites the second gas burner 1e, adjusts the heating heat to an appropriate value, and operates the circulation pump 1h.
[0025]
The timer control means 3 further includes a relative time data automatic change means 3f for automatically changing the relative time data for a specific hot water terminal 2 based on the operation state of the heat source device 1 or another hot water terminal 2. It is determined based on the event information whether or not another hot water terminal 2 (heat source device 1) is already operating at the set time for the specific hot water terminal 2, and if it is operating, The relative time data is changed to advance the set time for the specific hot water terminal 2. That is, if another hot water terminal 2 is operating before the specific hot water terminal 2 is operating, the temperature of the hot water circulating through the circulation pipe 1f has already risen, The operation time is controlled efficiently by shortening the set time for the rising time of the hot water terminal 2. As described above, when the relative time data by the relative time data automatic changing means 3f is updated based on the event information, the relative time data can be determined at the completion of the setting input of the event information, and is executed at that time. . In addition, the operation information from each of the terminal control means 2c described above is inputted, and the other hot water terminals are set before the set time of the specific hot water terminal (at least simultaneously with or before the relative time to the event occurrence time). It is also possible to determine whether or not the machine is in operation, and to change the relative time of a specific hot water terminal when it is determined that the machine is in operation.
[0026]
Also, if another hot water terminal 2 is set to operate immediately after the set time at which the specific hot water terminal 2 operates, hot water circulating in the circulation pipe 1f due to an increase in load. Since the rise time of the temperature is longer, the set time for the rise time of the specific hot water terminal 2 can be advanced to efficiently control the operation. Here, if the supply of hot water to the branch pipe 2a of each hot water terminal 2 is controlled to be on / off at a predetermined duty ratio, the phase of hot water supply on / off by the valve mechanism 2b between the hot water terminals that are operated simultaneously is determined. By shifting, the rising time of both temperatures can be controlled in a well-balanced manner. For example, the heat source unit 1 is provided with a sensor for measuring the temperature of the hot water in the return path of the circulation pipe 1f, and a control means for reducing the phase difference when the return water temperature is higher than the reference temperature and increasing the phase difference when the temperature is low. This can be realized by providing
[0027]
In this way, for example, the hot water supply / heating system is operated based on the time set by the event information according to the lifestyle of the morning of the day. For example, if the wake-up time is set to 6:00 as the event type, the hot water panel heater in the bedroom is activated at 5:00, one hour before the wake-up time, and the hot water floor heater in the living room 30 minutes before the wake-up time. , The hot water panel heater in the kitchen is activated 15 minutes before the wake-up time, and the hot water panel heater in the bedroom is stopped 15 minutes after the wake-up time. Further, if the work (going out) time is set to 7:30 as the event type, the hot water floor heater in the living room and the hot water panel heater in the kitchen are stopped at 7:30.
[0028]
Hereinafter, another embodiment will be described. In the above-described embodiment, a relative time data automatic change unit that automatically changes the relative time data with respect to the hot water terminal 2 based on the environmental condition of the heat source device 1 or the hot water terminal 2 may be further provided. Thus, for example, the temperature of the installation location of the hot water terminal, the installation area, the rise delay time until reaching a predetermined temperature based on environmental conditions such as the volume to be heated, to adjust the specific hot water terminal. It is possible to operate efficiently. In this case, it is necessary to configure an interface circuit in which the environment in which the respective hot water terminals are installed (such as the capacity of the space to be heated or the like or the detection value of the room temperature sensor can be input).
[0029]
In the control of the hot water terminal based on the event information described above, the operation and stop of the device have been mainly described. However, it is naturally possible to perform control such as changing the setting of the control temperature or the like accompanying the operation. Also, instead of or in addition to the above-mentioned automatic relative time data changing means based on the operating state and environmental conditions of the other equipment, the setting of the operating temperature and the like of the equipment is automatically performed based on the operating state and environmental conditions of the other equipment. The configuration may be changed to enable efficient operation.
[0030]
In the embodiment described above, the timer control means of the centralized control mode for individually operating or stopping or setting or controlling each of the hot water terminals at the set time includes a time keeping means, an event information input means, and an event correspondence control means. Although the configuration has been described, the configuration of the timer control means is not limited to this, and a distributed method in which timer control means is individually provided for each hot water terminal and event information can be input individually, Each hot water terminal is provided with a timer control means individually, and each event information input means is provided with communication means for transmitting and receiving event information from another hot water terminal via a communication line. You may. Further, an information processing device such as an event management server that manages event information is provided outside the hot water supply / heating system or in the heat source device, and the information processing device is provided with a timer control unit installed in each hot water terminal or the centralized control device described above. The timer unit in the control mode may be connected to a wired or wireless network as a communication unit, and may be configured to input event information from the information processing apparatus. In these configurations, each of the timer units provided in the timer control unit is a main timer unit installed in any of the timer control units, for example, a timer unit installed in the heat source device, so that a time lag does not occur. It is preferably configured to be synchronized with.
[0031]
In this case, a memory unit for storing event information is provided in each event correspondence control unit, and it is determined whether or not the event information is related to itself based on the terminal ID data of the event information input via the communication unit. If the event information is for itself, the event ID data, the occurrence time data, and the relative time data are fetched into the memory means, and the self control is performed based on the fetched event data. Here, if the event ID data and the relative time data with respect to the event ID data are set and stored in advance in the memory means provided in each event correspondence control means, then at least the event information transmitted via the communication means includes Relative time data can be omitted. In such a configuration, the operation state of the other hot water terminal device can be recognized by recognizing the event information for the other hot water terminal device included in the event information. It is possible to provide.
[0032]
The above-mentioned event information is naturally set and operated by a plurality of operators in the home, and different time data (event occurrence time data or relative time data) for the same hot water terminal by each operator. Is set, the most recently set data can be made effective. In addition, even if the event is the same, the event ID data may be different for each member of the family so that each event data can be set. In this case, when different event information for the same hot water terminal is set, if the set time for starting overlaps, the earlier one takes precedence, and if the set time for stopping overlaps, the earlier one takes precedence. It is preferable that the priority handling means for controlling the event is provided in the event handling control means.
[0033]
According to the hot water supply / room heating system described above, the control target of the timer control means has been described as being limited to the hot water terminal connected to the heat source device. The configuration may be made possible. With this configuration, it is possible to comprehensively control the reservation operation such as the operation of various devices in the home at the set time according to the life pattern.
