Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This device reheats the hot water in the bathtub repeatedly at intervals, and terminates the reheating every time the actual hot water temperature in the bathtub reaches a predetermined set temperature, thereby performing an automatic warming operation. The present invention relates to a combustion control device that performs an automatic heat-retention operation repeatedly during a heat-retention duration set as a fixed value in advance.

[0002]

[Prior art]

 In the combustion control device that keeps the temperature of the hot water in the bathtub at the set temperature, the duration of the warming operation is a fixed value that is set in advance and cannot be changed arbitrarily by the user.

[0003]

[Problems to be solved by the invention]

 However, as described above, if the duration of the warming operation is fixed, for example, in a large family, the time from the first bather to the last bather varies, and when the last bather takes a bath, the warming is maintained. In many cases, the heat retention operation has ended after the operation duration has elapsed, and when the outside air temperature is low, such as in winter, the temperature of the hot water in the bathtub may drop significantly.

[0004] In such a case, the bather again performs reheating to an appropriate temperature, but the longer the reheating time to the appropriate temperature, the more discomfort of the bather increases. It is also a waste of time.

[0005] Even if they are not a large family, the time until a bather takes a bath varies, and there has been a strong demand for adjusting the duration of the warming operation.

The present invention has been proposed in view of the above, and an object of the present invention is to provide a combustion control device that allows a user to easily change an automatic warming operation continuation time.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the combustion control device of the present invention repeatedly reheats the hot water set in the bath tub at intervals of time, and every time the actual hot water temperature in the bath tub reaches a predetermined set temperature. After the reheating is completed, the automatic heat retention operation is performed, and within the preset heat retention time, the combustion control device that repeats the automatic heat retention operation sets the above heat retention time according to the user setting. It is characterized by providing a means for changing the heat retention duration that can be changed arbitrarily.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the combustion control device of the present invention. In the figure, the combustion control device 1 of the present invention repeatedly reheats hot water 11a stretched in the bathtub 11 of the bathtub section 10 at time intervals, and sets the actual hot water temperature in the bathtub 11 to a predetermined temperature. Each time the temperature is reached, the reheating is terminated and the automatic heat-retention operation is performed. Within the preset heat-retention time, the combustion control device 1 that repeats the automatic heat-retention operation sets the heat retention time for the user. It is characterized in that a heat retention duration changing means (23, 3, 7, etc.) arbitrarily changed by setting is provided.

The combustion control device 1 includes a remote controller (hereinafter, referred to as “remote control”) 1A and a control device main body 1B. The remote control 1A includes a microcomputer 3, a switch unit (operation unit) 2, It comprises a display unit 4 and a communication control unit 5. The microcomputer 3 includes a CPU, a ROM, a RAM, and the like (not shown), generates various signals based on a program and the like according to the present invention stored in a ROM, and transmits the signals to a communication control unit. 5 to the control device body 1B.

The switch unit 2 of the remote controller 1A includes various switches required for the operation of the combustion control device 1, for example, a power switch 21 for turning on and off the combustion control device 1, and a heat insulation for turning on and off an automatic heat insulation operation. A switch 22 and a heat retention duration change switch (hereinafter referred to as “time change switch”) 23 for setting the heat retention duration are provided.

The control device main body 1 B mainly includes a microcomputer 7 and includes an EEPROM (electrically erasable PROM) 2, a combustion control unit 6, and a communication control unit 5. Similar to the microcomputer 3 of the remote controller 1A, the microcomputer 7 includes a CPU, a ROM, a RAM (not shown) and the like, and various types of the microcomputer 7 are stored in the ROM according to the present invention. The signal is generated and output to the combustion control unit 6. In this case, the microcomputer 7 generates various signals with reference to the signal from the remote controller 1A entered via the communication control units 5 and 9 and the data stored in the EEPROM 2.

The combustion control unit 6 controls a proportional valve, a solenoid valve, and the like (not shown) of the bathtub unit 10 based on various signals output from the microcomputer 7 to adjust the amount of supplied heat and the amount of water. Then, for example, an automatic warming operation (automatic warming control) is performed. That is, the hot water 11a stretched in the bathtub 11 is repeatedly reheated at intervals of time, and the reheating is completed each time the actual hot water temperature in the bathtub 11 reaches a predetermined set temperature. Perform the operation.

Next, an automatic warming operation performed by the combustion control device 1 will be described. In order to perform the automatic warming operation, first, the warming switch 22 of the switch unit 2 is turned on. In response to the ON signal, the microcomputer 3 of the remote controller 1A transmits a warming operation continuation time (hereinafter, referred to as “set time”) T0 previously set as an initial value in the EEPROM 8 of the control device body 1B to the communication control unit. 5, read out via the communication line 20 and the communication control unit 9 and displayed on the display unit 4, subtract the elapsed time from the set time T0, and use the subtracted time as the remaining time until the end of the automatic warming operation. Display as T on the screen. Further, the microcomputer 3 receives the ON signal of the heat retention switch 22 and transmits an automatic heat retention operation start signal to the control device body 1B via the communication control unit 5 and the communication line 20.

The microcomputer 7 of the control device main body 1B receives the automatic warming start signal via the communication control unit 9, starts predetermined automatic warming control based on the start signal, and continues until the set time T0 elapses. Continue to do so.

On the other hand, in order to change the set time T0 of the automatic warming operation, the time change switch 23 of the switch unit 2 is turned on during the above automatic warming operation. When the time change switch 23 is turned on, the set time T0 is displayed on the display unit 4 on a screen. For example, when the time change switch 23 is pressed once, the set time T0 displayed on the screen is changed by "1". For one hour, it is added or subtracted. When the set time T0 is changed to T1 in this manner, the microcomputer 3 of the remote controller 1A displays the new set time T1 on the screen of the display unit 4, and displays the elapsed time thereafter as the new set time. The time is subtracted from T1, and the subtracted time is displayed on the screen as the remaining time T until the end of the automatic warming operation. Further, the set time T1 is transmitted to the control device main body 1B via the communication control unit 5, the communication line 20, and the communication control unit 9.

The microcomputer 7 of the control device main body 1B writes the transmitted set time T1 in the EEPROM 8 to update the set time, and performs the subsequent heat keeping operation control with the time width of the updated set time T1. .

Further, the subsequent time change by the time change switch 23 is also performed for the new set time T1.

In the above description, when the time change switch 23 is turned on, the set time T0 is displayed on the display unit 4 and the set time T0 is changed. However, the setting is performed by another setting method. You may do so. For example, when the time change switch 23 is turned on, a change may be made to the remaining time T displayed on the display unit 4. In this case, for example, when the time change switch 23 is pressed once, the remaining time T displayed on the screen is incremented or decremented by "1", that is, by one hour.

Although the time is changed in one-hour units, a button for changing in minutes may be added, and the time may be changed in one-minute units.

As described above, in this embodiment, the set time T0 of the continuation of the automatic warming operation can be arbitrarily changed. Therefore, the set time T0 (T1) is set according to the manner in which the bathtub 11 is used. ) Can be adjusted to the optimal one. For example, if a large family needs to continue the automatic warming operation for a long time, the setting time can be lengthened.If a small number of family members need only a short duration, the setting time can be shortened. it can. Therefore, in the case of a large family in the past, it is necessary to take a bath again after the end of the set time T0, and it is necessary to re-boil again. Can be reduced. In the past, in the case of a small number of families, the automatic warming operation may continue even after all the bathers have finished bathing due to forgetting to turn off the power, etc.Similarly, wasteful time and fuel was wasted, but such waste was reduced. can do. Therefore, energy saving can be realized and it can contribute to improvement of environmental problems.
