Description

The present disclosure relates to a hot water storage type water heater.

For example, Patent Document 1 describes a work of setting a water level in a bathtub of a water heater. Specifically, in Patent Document 1, as the water level setting work, the value obtained by converting the physical value such as the voltage obtained from the water level sensor into a digital value corresponding to the actual bathtub water is registered in the remote controller and set by the remote controller operation.

Further, the water heater described in Patent Document 1 is configured so that when an operator mistakenly inputs data for setting a water level, the water heater can be reset by performing a predetermined remote control operation.

Japanese Unexamined Patent Publication No. 6-288611

A control program for controlling the operation of the water heater is stored in the control device of the water heater, and the operation of the water heater is controlled by executing this control program. Therefore, if an execution error of the control program occurs, for example, an illegal infinite loop occurs during the execution of the control program, an abnormal state may occur in which some functions of the water heater do not operate normally. On the other hand, the reset method described in Patent Document 1 is a method of resetting the data for setting the water level, and cannot eliminate the abnormal state due to the execution error of the control program.

Even if the water heater falls into an abnormal state, the abnormal state may be resolved by operating the reset operation switch. However, the reset operation switch is often installed in a place that cannot be touched by the user, such as on a control board built in a water heater. In this case, if the water heater falls into an abnormal state, it will wait for the visit of the resetting company. On the other hand, it is conceivable to separately provide an operation switch dedicated to resetting in a place where the user can easily operate it. However, the installation of an operation switch dedicated to resetting is not preferable from the viewpoint of reducing the product cost. In addition, it may be necessary to wait for a long time with the water heater unplugged for the reset process. In this case, the water heater cannot be used for a long time due to the reset process. Therefore, it is desired to develop a technology that allows the user to easily recover the water heater in a short time even if the water heater falls into an abnormal state.

This disclosure is made to solve the above-mentioned problems, and the user can recover the hot water storage type water heater from an abnormal state in a short time and easily without operating a dedicated reset operation switch or the like. It is an object of the present invention to provide a hot water storage type water heater improved as described above.

The hot water storage type water heater according to the present disclosure includes a hot water storage unit having a hot water storage tank, a hot water storage unit control unit that controls the operation operation of the hot water storage unit according to an operation control program stored in advance, and a remote controller. The remote controller has an operation unit that accepts operation inputs of commands related to the operation of the hot water storage unit, and a remote controller control unit that is connected to the hot water storage unit control unit so as to be able to communicate in both directions and controls the remote controller according to a remote control control program stored in advance. To prepare for. The remote control unit sends a reset signal to the hot water storage unit control unit when the operation unit receives the input of a specific operation, and the hot water storage unit control unit resets the control state of the hot water storage unit to the initial state when the reset signal is received. It is configured to perform a reset process to return.

According to the hot water storage type water heater according to the present disclosure, even if the hot water storage type water heater becomes abnormal due to an error in the control program, the user can easily perform the recovery work in a short time by operating from the remote controller. Can be done.

By detecting the distribution of the water temperature in the vertical direction based on the outputs of the first to fourth temperature sensors 5a to 5d, the amount of heat stored and the amount of remaining hot water in the hot water storage tank 1 can be detected. Further, the hot water storage tank temperature sensor 6 is provided on the upper part of the hot water storage tank 1 and emits an output according to the temperature of the hot water heated by the heat pump unit 2 and returned to the upper part of the hot water storage tank 1.

The hot water supply side electric mixing valve 7 and the bath side electric mixing valve 11 have hot water from the hot water supply pipe 8 connected to the upper part of the hot water storage tank 1 and water from the water supply pipe 9 connected to a water source such as a water pipe, respectively. Is mixed at the mixing ratio according to the set temperature, and the temperature of the hot water to be supplied is adjusted. The hot water whose temperature is controlled by the electric mixing valve 7 on the hot water supply side is supplied to the faucet or the like via the mixing hot water supply pipe 10.

The hot water whose temperature is controlled by the bath-side electric mixing valve 11 is supplied via the mixing bath pipe 18 and the bath-side circulation circuit 12. A solenoid valve 13 is installed in the mixing bath pipe 18. The solenoid valve 13 stops the hot water supply when the amount of hot water in the bathtub reaches the set amount, and completes the hot water filling into the bathtub.

The water supply pipe 9 is provided with a water supply temperature sensor 23 for detecting the temperature of the water flowing through the water supply pipe 9.

Has been done.

A bathtub (not shown) is connected to the bath side circulation circuit 12. A bath circulation pump 14 is installed in the middle of the bath side circulation circuit 12. The bath-side circulation circuit 12 is a path for drawing in the bath water from the bathtub by the bath circulation pump 14 and returning it to the bathtub via the heat exchanger 15.

The tank-side circulation circuit 16 is connected to the hot water storage tank 1. A tank circulation pump 17 is installed in the middle of the tank-side circulation circuit 16. The tank-side circulation circuit 16 is a path for drawing hot water in the tank from the upper part of the hot water storage tank 1 by the tank circulation pump 17 and returning it to the lower part of the hot water storage tank 1 via the heat exchanger 15.

In the heat exchanger 15, heat exchange is performed between the bath water flowing through the bath-side circulation circuit 12 and the hot water flowing through the tank-side circulation circuit 16, and the bath water is heated. The reheating of the bath water is started by driving the bath circulation pump 14 and the tank circulation pump 17. Then, when the bath water reaches the set hot water temperature due to the heating of the bath water in the heat exchanger 15, the operation of the bath circulation pump 14 and the tank circulation pump 17 is stopped, and the reheating of the bath water is completed. do.

The remote controller 25 is an example of a user interface. Although not shown, the remote controller 25 includes an operation unit and a display unit. The operation unit has a plurality of operation switches for the user to input an operation command to the hot water storage unit 26 and changes of various set values. The display unit displays information such as the operation content by the operation unit, the operating state of the hot water storage unit 26, and various settings. The remote controller 25 is provided with a display unit as a notification means for notifying the user of information, but as a modification, other notification means such as a voice guidance device may be provided. Further, the remote controller 25 may include a touch screen having both functions of an operation unit and a display unit.

Although not shown, the remote controller 25 includes a remote controller control unit that controls the operation of the remote controller 25. The remote control control program is stored in advance in the remote control control unit, and the remote control control unit can control the operation of the remote control 25 according to the remote control control program.

In the present embodiment, the remote controller 25 may be installed on a wall such as a kitchen, a living room, or a bathroom. A plurality of remote controllers 25 may be provided. Instead of the remote controller 25, or in addition to the remote controller 25, a mobile terminal such as a smartphone may be configured to be used as a user interface.

The control unit 24 functions as a hot water storage unit control unit that controls the hot water storage unit 26 and also functions as a heating unit control unit that controls the heat pump unit 2. The control unit 24 has at least one memory and at least one processor. Further, the control unit 24 has a calendar function for managing the date and time. The control unit 24 is not limited to a single control unit, and may be configured such that a plurality of control units cooperate to control the control unit 24.

The control unit 24 includes a heat pump unit 2, an HP circulation pump 4, first to fourth temperature sensors 5a to 5d, a hot water storage tank temperature sensor 6, a hot water supply side electric mixing valve 7, a bath side electric mixing valve 11, and an electromagnetic valve 13. Bath circulation pump 14, tank circulation pump 17, hot water supply flow sensor 19, hot water supply temperature sensor 20, bath flow rate sensor 21, bath temperature sensor 22, water supply temperature sensor 23, remote control unit of remote control 25, and electricity. Is connected. The control unit 24 receives the detection result data from various sensors and the like, and also receives the information regarding the operation input received by the remote controller 25. Further, the control unit 24 controls the communication with the remote controller 25 and controls the operation of each actuator built in the hot water storage type water heater to control the operation operation of the hot water storage type water heater.

The operation control program is stored in the control unit 24. The control unit 24 controls the operation operation of the hot water storage type water heater by executing this operation control program. Specifically, for example, the control unit 24 operates the operation when hot water is applied to the bathtub, and automatically keeps the hot water in the bathtub at a set amount and temperature for a predetermined period after the hot water is completed. Control the operation of the function. Further, for example, the operation of the boiling operation performed in the midnight power time zone is controlled.

However, some functions of the hot water storage type water heater may become abnormal due to an error such as an illegal infinite loop of the operation control program during execution of control of the operation operation of the hot water storage type water heater. be. On the other hand, in the present embodiment, the control of the reset process for returning the hot water storage type water heater in the abnormal state to the initial state is executed by the cooperation between the remote control unit and the control unit 24. FIG. 2 is a flowchart showing a control operation of the reset process of the hot water storage type water heater according to the present embodiment. Hereinafter, the control operation of the reset process will be described with reference to FIG.

The user can start the reset process by inputting a specific operation from the operation unit of the remote controller 25. The content of the specific operation is preset and stored in the remote control unit. In the present embodiment, for example, in the specific operation, among the plurality of operation switches of the operation unit, all of the specific operation switches (hereinafter, also referred to as “3 switches”), which are three operation switches in which a combination is set in advance, are used. It is defined that the pressed state has continued for a reference time or longer. As an example, the operation switch of "selection ▲", the operation switch of "decision" for inputting the input or the determination of the selected content, and the "temperature setting-" for starting the input of the set value such as the hot water supply temperature. It is a combination of operation switches.

Here, the operation switch of "Select ▲" can change the time by pressing it on the date / time change screen after pressing the date / time setting operation switch, or the number of days after pressing the stop days operation switch. It is an operation switch that can change the number of days by pressing it on the change screen. However, the operation switch of "selection ▲" is an operation switch that does not change the setting of the hot water storage type water heater even if only the operation switch of "selection ▲" is pressed first. In addition, an operation switch for raising the temperature is provided separately, and the temperature setting cannot be changed with the operation switch of "Select ▲".

In step S1 of FIG. 2, the remote control control unit determines whether or not all three switches are pressed. If it is determined in step S1 that all three switches have not been pressed, the process returns to S1 and the determination process in step S1 has a constant control interval until it is determined that all three switches are pressed. Is repeated at.

On the other hand, if it is determined in step S1 that all three switches are pressed, then the process proceeds to step S2, and it is determined whether or not the reference time has elapsed after all three switches have been pressed. Will be done. Here, the reference time is set in advance to a time sufficient to distinguish between the case of an operation error and the case where the user intentionally presses the 3 switch. The reference time is, for example, 5 seconds.

If it is determined in step S2 that the reference time has not elapsed, the process is returned to step S1. The determination process of steps S1 to S2 is repeated until the passage of the reference time is recognized in step S2.

On the other hand, if it is determined in step S2 that the reference time has elapsed, the next step is to proceed to step S3, and the remote control control unit transmits a reset signal to the control unit 24 of the hot water storage unit 26. In step S4, the control unit 24 receives the reset signal.

Next, in step S5, a reset process for returning the control state of the hot water storage unit 26 to the initial state is executed. Specifically, the control unit 24 executes an operation control program for controlling the operation of the hot water storage unit 26 from the beginning. As a result, the control state of the hot water storage unit 26 is returned to the initial state. After that, this process is terminated.

As described above, according to the present embodiment, even when the hot water storage type water heater falls into an abnormal control state, the user performs a specific operation from the remote controller 25 to initialize the control state of the hot water storage unit 26. It can be returned to the state. As a result, the user himself / herself can easily and quickly execute the reset process even when the hot water storage type water heater is installed outdoors without providing a dedicated reset operation switch.

In this embodiment, a combination of a "selection ▲" operation switch, a "decision" operation switch, and a "temperature setting-" operation switch is exemplified as three switches for specific operations for starting a reset signal. However, the three switches are not limited to this, and may be a combination of other operation switches. Further, the specific operation switch is not limited to the combination of three switches, and may be a combination of two operation switches or four or more operation switches among a plurality of operation switches provided in the operation unit of the remote controller 25.

However, it is desirable that the specific operation switch set as the specific operation is an operation switch other than the operation switch for raising the set temperature among the plurality of operation switches provided in the operation unit of the remote controller 25. As a result, it is possible to prevent the set temperature from rising even when the pressing timings of the first operation switch and the other operation switches are different.

In addition, the 3 switches set as specific operations can be used to issue commands or settings to the hot water storage type water heater even when one of the three switches is not pressed and two operation switches are pressed. It is desirable that the operation switch does not serve as a specific operation input. As a result, even when only two of the three switches are pressed, it is possible to prevent the occurrence of an erroneous operation that is an operation input of another command. Similarly, when the number of specific operation switches is 4 or more, the combination of the specific operation switches is the combination of the remaining 2 or more operation switches excluding any 1 or more, and all of them are for the hot water storage type water heater. It is desirable that it should not be used for inputting any specific command.

Further, it is desirable that the operation switch set as the specific operation switch is an operation switch arranged at a position not adjacent to each other. As a result, it is possible to suppress the occurrence of erroneous operation due to erroneous pressing of the adjacent operation switch.

Further, the control unit 24 may be configured to include a self-diagnosis means for diagnosing the presence or absence of an abnormality and the content of the abnormality in the hot water storage unit 26 by using signals from various electrically connected parts and various sensors. In this case, when the control unit 24 receives the reset signal, the self-diagnosis means diagnoses the abnormal content, and the reset process returns the control state of the hot water storage unit to the initial state according to the diagnosed abnormal content. It may be configured to determine whether or not to execute. More specifically, for example, when the abnormal content is an abnormal content that has a large effect on the user, the reset process may be prohibited from being executed. Here, the content of the abnormality having a large influence on the user is, for example, the case where the hot water supply is stopped due to a high temperature hot water discharge error in which the hot water supply temperature becomes higher than a predetermined temperature. As a result, when the hot water storage type water heater is stopped due to another abnormality, it is possible to prevent the hot water storage type water heater from being inadvertently reset and become usable.

Further, in the present embodiment, the case where the control unit 24 executes the reset process by executing the operation control program of the hot water storage unit 26 from the beginning when the reset signal is received has been described. As a result, even when an error such as an illegal loop occurs in the operation control program, the control state can be returned to the initial state, and the hot water storage unit 26 can be easily restored.

However, the control unit 24 is configured to execute a process of returning the values held inside the microcomputer of the control unit 24 to the initial state, such as a timer and a microcomputer input / output port setting, as a reset process. You may. As a result, the value held inside the microcomputer becomes an abnormal value, and even if some functions of the hot water storage type water heater are in an abnormal state, the user can reset it by operating the remote controller 25. By starting the treatment, the hot water storage type water heater can be restored easily in a short time.

Further, the control unit 24 is configured to execute, as a reset process, a process of returning the data stored in the microcomputer such as the value set by the user such as the hot water supply temperature and the learning data such as the amount of hot water used in the past to the initial value. It may be a new one. In this case, for example, a reset program for erasing the data in the data area storing only the data of the control unit 24 is separately prepared, and this reset is performed when the control unit 24 receives the reset signal. You may try to execute the program. As a result, even if the user memorizes incorrect data, or if the data stored in the microcomputer becomes an abnormal value, it can be easily returned to the initial state in a short time by operating from the remote controller, and the hot water storage type. The water heater can be restored.

In addition, as a reset process, the control unit 24 performs a process of executing the operation control program from the beginning, a process of returning the values held inside the microcomputer such as a timer and a port setting to the initial state, and data stored in the microcomputer. It may be configured to execute all of the processes for returning to the initial value, or any two or more of these processes.

Further, the remote control control unit may be configured to execute a process of returning the control state of the remote controller 25 to the initial state as a reset process when the input of a specific operation is received. The reset process of the remote controller 25 can be performed, for example, by executing the remote controller control program stored in the remote controller control unit from the beginning. As a result, even if some functions of the remote controller 25 do not operate normally and an abnormal state occurs, the remote controller 25 can be easily put into an abnormal state in a short time by simply inputting a specific operation to the remote controller 25. Can be restored from.

Further, the hot water storage type water heater may have a remote controller 25 as a first remote controller and a second remote controller as another remote controller. Specifically, for example, the first remote controller is a kitchen remote controller installed in the kitchen, and the second remote controller is a bathroom remote controller installed in the bathroom. In this case, it is assumed that the first remote controller and the second remote controller are connected so as to be able to communicate in both directions. In the case of the configuration having two remote controllers 25 as described above, the reset process of the remote controller can be executed as follows.

That is, when the operation unit of the first remote controller receives a specific operation by the user, the control unit of the first remote controller executes a reset process for returning the control state of the first remote controller to the initial state, and also performs a reset process with the control unit 24. A reset signal is transmitted to the control unit of the second remote controller. When the control unit of the second remote controller receives the reset signal, the control unit of the second remote controller returns the control state of the second remote controller to the initial state.

Further, the hot water storage type water heater may be configured to have three or more remote controllers capable of bidirectional communication with each other. Similarly in this case, when one remote controller accepts the input of a specific operation, the reset signal is transmitted to all the other remote controllers, and the control unit of the other remote controller receiving the reset signal controls each remote controller. It can be configured to return the state to the initial state. As a result, even if the hot water storage type water heater is equipped with multiple remote controllers and one of the remote controllers falls into an abnormal state, the user simply inputs a specific operation to one remote controller 25, and all the remote controllers are in the control state. Can be restored to the initial state and the hot water storage type water heater can be restored.

Further, in the case where the heat pump unit 2 has a heating unit control unit as a control unit for controlling the heat pump unit 2, after the remote control 25 receives a specific operation, the remote control control unit goes through the control unit 24 of the hot water storage unit. Therefore, a reset signal may be transmitted to the heating unit control unit. In this case, the heating unit control unit that has received the reset signal can be configured to return the control state of the heat pump unit 2 to the initial state by executing the control program that controls the operation operation of the heat pump unit 2 from the beginning. .. As a result, even if the heat pump unit 2 mainly installed outdoors falls into an abnormal state in which some functions do not operate normally, the user inputs a specific operation to the remote controller 25 without going outdoors. The heat pump unit 2 can be restored only by itself.

The hot water storage type water heater according to the present disclosure resets the control state of the hot water storage unit 26 executed by the control unit 24 to the initial state and resets the control state of the remote controller 25 to the initial state when the user inputs a specific operation. It may be configured to execute all of the process of returning and the process of returning the control state of the heat pump unit 2 to the initial state, or it may be configured to execute any two or more of these processes.

Further, in the hot water storage type water heater according to the present embodiment, during the reset process, the display unit provided on the remote controller 25 is in the middle of the reset process from the input of the specific operation to the remote controller 25 until the reset process is completed. By displaying that, it may have a configuration for notifying the user that the reset process is in progress. In this case, the specific content of the reset process may be notified, for example, the control state of the hot water storage unit 26 is returned to the initial state. Further, the notification is not limited to the display on the display unit, and may be a notification using voice guidance or the like. As a result, the user can easily confirm that the reset process has been normally accepted, and can recognize that the reset process is in progress and other operations may not be accepted.
