Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a water heater in a hot water supply system equipped with a bath water reheating circulation system.

[Prior Art] In recent years, water heaters have been remotely controlled by a remote control installed in the kitchen or bathroom of a general household, and hot water is supplied to the hot water supply equipment in the bathroom or the hot water in the bathtub is circulated through the water heater. A hot water supply system that uses reheating has been developed.

In such a hot water supply system, for example, a hot water supply piping mechanism is used that supplies water from a tap or the like to a heat exchanger of a combustor, heats it, and then supplies the heated hot water to a hot water supply facility such as a bathroom. We are prepared.

In addition, as a reheating piping mechanism, one is considered to have a configuration in which hot water in the bathtub is circulated through the heat exchanger of the combustor via a water flow detection switch and a circulation pump to reheat it. Each of these mechanisms can be remotely controlled by remote controllers located mainly in the kitchen and bathroom, and hot water can be supplied to a predetermined temperature or reheated based on desired set values.

Each of these remote controllers is independently supplied with power, and displays the operating status of the hot water supply or reheating function by dimming light emitting diodes or lamps on the panel surface, and when not in use. Currently, the power to the remote controllers themselves is individually cut off in order to save on power consumption.

[Problems to be solved by the invention] However, in the case of a water heater using a remote control as described above, the operation is frequently performed, and if the remote control power is turned on and off frequently,
It is very cumbersome to operate as it is necessary to set the temperature for hot water supply or reheating each time.
Moreover, in systems that allow the setting of unique hot water temperatures in the kitchen and bathroom, the remote control itself has a memory function that allows it to restart the system from a shutdown state due to a power cut, based on the set value before shutdown. Have difficulty.

Furthermore, since the required temperatures are different in the kitchen and the bathroom, there is a problem in that each time the kitchen and bathroom are used, the hot water temperature must be adjusted using a remote control, which is a cumbersome operation.

This invention was developed under the above circumstances, and its purpose is to easily perform hot water supply or reheating based on the temperature set before the operation was stopped when restarting the operation from a stopped state, and to ,bathroom,
It is possible to check the temperature setting status of the remote controller installed in multiple locations such as the kitchen from one remote controller, and you can simply turn the priority switch ON/OFF without operating the hot water temperature adjustment on the remote controller. An object of the present invention is to provide a water heater that can obtain the desired temperature.

[Means for Solving the Problems] In order to solve the above-mentioned problems, this invention supplies hot water to the heat exchanger of the combustor, heats it up, and supplies it to the hot water supply equipment in the bathroom or kitchen. A water heater, which is capable of being remotely controlled by first and second remote controllers installed at a plurality of locations where hot water is used in different ways, and wherein the desired remote controller is provided with a priority switch;
When this priority switch is activated, the temperature setting display set on the remote controller equipped with the priority switch is simultaneously displayed on the other remote controller not equipped with the priority switch, while the priority switch is not activated. In this case, the temperature setting display set on the remote controller without a priority switch is simultaneously displayed on the remote controller equipped with the priority switch, and the setting value during hot water supply set by each of the remote controllers is The setting value is stored in the memory section of the control mechanism that is always energized, and the setting value based on the memory contents before the hot water supply operation was stopped can be simultaneously displayed on the indicators of each remote control when the operation is restarted from the stopped state. It is something.

[Function] That is, by having the above-mentioned configuration, this invention stores the set values set by each remote controller during hot water supply in the storage section of the control mechanism that is always energized, and stops the hot water supply operation. When restarting from a stopped state, the set values based on the previous memory contents are set.
Since the indicators of each remote controller can be displayed simultaneously, it is possible to check the temperature setting status of one remote controller according to the operation of each remote controller.

In addition, even if the power to the remote control is cut off when not in use, the control mechanism is always energized by commercial alternating current, so the previous memory content is not erased, and as a result, operation can be stopped. When restarting from the current state, it becomes possible to easily and quickly perform hot water supply or reheating based on the temperature set before the operation is stopped.

Furthermore, each remote controller stores each required temperature, so the required temperature in the kitchen, bathroom, etc., for example, can be obtained by simply turning the priority switch on and off, without having to operate the hot water temperature adjustment on the remote controller.

Furthermore, if each remote control is installed in the kitchen and bathroom, it is possible to adjust the temperature in both the kitchen and bathroom, and since the information can be displayed on each remote control at the same time, it is easy to distinguish the temperature setting. can be done.

[Example] Hereinafter, this invention will be explained in detail with reference to an illustrated example.

FIG. 1 is a circuit configuration diagram schematically showing a hot water supply system for a hot water supply facility such as a bathroom equipped with a water heater according to this invention, and numeral 1 in the figure is the main body of the water heater. In this water heater main body 1, water C and W from a water supply etc. are supplied to a heat exchanger 4 of a combustor 3 that burns kerosene F supplied from a kerosene tank 2 as fuel. A hot water supply piping mechanism 5 that supplies hot water H and W heated and heated by a heat exchanger 4 to, for example, a bathtub A in a bathroom, The hot water is circulated through the heat exchanger 4 of the combustor 3 through circulation ports 6 and 7 facing the combustor 3 for reheating, and the hot water intake circulation of the reheating piping mechanism 8. In the circulation flow path 10 on the side of the opening 6, a water flow detection switch 11 is installed on the upstream side to detect the normal water level of hot water H/W in the bathtub A in the OFF state.
A circulation pump 12 for forcibly circulating the hot water H and W in the bathtub A is installed on the downstream side thereof.

A first hot water temperature detector 13 for detecting the hot water temperature is installed in the hot water supply piping mechanism 5, while a circulation flow path 10 on the hot water circulation port 6 side of the reheating piping mechanism 8 is provided with a first hot water temperature detector 13 for detecting the hot water temperature. , a second hot water temperature detector 14 for detecting the bath water temperature is installed, and each of these hot water temperature detectors 1
The respective hot water temperature detection data detected by 3 and 14 and the operating state data of the circulation pump 12 are as follows:
Information is input to the microcomputer 17 via the input/output section 16 of the control device 15, processed by the microcomputer 17, and stored and held in the storage section 18. The control signal is transmitted to the input/output section 16.
The combustor 3 and the circulation pump 12 are automatically controlled to supply hot water or reheat the water, and the power supply section 19
is always connected to a commercial alternating current, so that the control device 15 itself always functions.

Further, in the figure, 20 is a first bathroom remote control installed in the bathroom, 21 is a second kitchen remote control installed in the kitchen, and the bath water temperature or hot water temperature setting is set with each of these remote controllers 20 and 21. Information is input to the microcomputer 17 via the input/output unit 16 of the control device 15, and predetermined information is processed by the microcomputer 17 and stored and held in the storage unit 18. The stored information stored in the storage section 18 is sent to the indicator 20a of the bathroom remote controller 20 and the indicator 21a of the kitchen remote controller 21 through the input/output section 16 so that the lights can be displayed. . Furthermore, 22 in the figure is a priority switch provided on the bathroom remote controller 20.

That is, in the above-mentioned control device 15, even if the bathroom remote controller 20 and the kitchen remote controller 21 are powered off, the storage unit 18 stores the previously set values for hot water supply or reheating operation, When restarting from a stopped state, each remote controller 20, 21 sets the setting value based on the memory contents before stopping.
Indicators 20a and 21a are displayed simultaneously, and the water heater 1 can be started and controlled based on such stored setting values.

In this way, the setting values of this invention are displayed on the indicators 21a, 21a based on the stored contents of the storage section 18 of the control device 15, but as shown in FIG. By operating the priority switch 22 provided in the bathroom remote controller 20, the setting display of the temperature set in the bathroom remote controller 20 is simultaneously displayed on the kitchen remote controller 21, and when the priority switch 22 is not activated, the temperature set in the kitchen remote controller 21 is displayed. The settings can be displayed on the bathroom remote controller 20 at the same time.

Note that this invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without changing the gist of this invention.

[Effects of the invention] As is clear from the above explanation, this invention is a water heater that supplies water to a heat exchanger of a combustion machine to heat and raise the temperature, and then supplies hot water to a hot water supply equipment in a bathroom or kitchen. and the water heater can be remotely controlled by first and second remote controllers provided at a plurality of locations where hot water is used in different ways, and the desired remote controller is provided with a priority switch,
When this priority switch is activated, the temperature setting display set on the other remote controller without the priority switch is simultaneously displayed on the remote controller with the priority switch, while the priority switch is not activated. In this case, the temperature setting display set on the remote controller without a priority switch is simultaneously displayed on the remote controller equipped with the priority switch, and the setting value during hot water supply set by each of the remote controllers is The setting values are stored in the storage section of the control mechanism that is always energized, and the set values based on the stored contents before the hot water supply operation was stopped can be simultaneously displayed on the indicators of each remote control when the operation is restarted from the stopped state. Depending on the operation of each remote controller, the temperature setting status of one remote controller can be checked from the other remote controller.

In addition, even if the power to the remote control is cut off when not in use, the control mechanism is always energized by commercial alternating current, so the previous memory content is not erased, and as a result, operation can be stopped. When restarting from the current state, hot water supply or reheating can be easily and quickly performed based on the temperature set before the operation is stopped.

Furthermore, each remote controller stores each required temperature, so you can obtain the required temperature in the kitchen or bathroom, for example, by simply turning the priority switch ON/OFF without having to operate the hot water temperature adjustment on the remote controller. I can do it.

Furthermore, if you install each remote control in the kitchen and bathroom, you can adjust the temperature in both the kitchen and bathroom, and since the display is displayed on each remote control at the same time, you can easily adjust the temperature settings. This has an excellent effect in that it can be easily distinguished.
