Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath water heater having an electrocardiographic information notification function for notifying the electrocardiographic information of a bather immersed in a bathtub to a bather or a third party other than the bather. It is a thing.

[0002]

2. Description of the Related Art Conventionally, as disclosed in, for example, Japanese Patent Application Laid-Open No. 5-95921, an electrocardiographic information notification system for informing a bather or the like of electrocardiographic information such as the heart rate of a bather immersed in a bathtub. Has been known for a long time. This electrocardiographic information notification system uses electrodes installed in the bathtub to detect electrocardiographic signals such as the heart rate of the bather immersed in the bathtub and the electrocardiographic signal of the bather detected by this electrode. It is composed of an electrocardiographic information creation unit, such as a CPU, which calculates electrocardiographic information such as the heart rate based on the display unit, and a display unit which displays electrocardiographic information. The bathers immersed in the bathtub are continuously displayed. Based on the electrocardiographic information, it is possible to grasp the change in the state of one's own heart. On the other hand, in the bathroom, a remote controller for remotely controlling heat source devices such as water heaters and bath water heaters is installed, and the remote controller for the heat source device is installed and installed on the wall surface of the bathroom in addition to the display of the ECG information notification system. This is not preferable in terms of operation or aesthetics, since the operation is complicated and the appearance is not good. To solve this problem, one display unit can be shared.

[0003]

An amplifier circuit 27 and a microcomputer 28 to which the electrocardiographic signal amplified by the amplifier circuit 27 is input are provided, and the microcomputer 28 calculates the heart rate per minute based on the input electrocardiographic signal. Then, this heart rate is transmitted to the controllers 15 and 14 of the bath remote controller 3 and the kitchen remote controller 4 via the serial interface (I / F) 29.

Next, with reference to FIG. 7, a method of displaying the bath remote controller 3 and the kitchen remote controller 4 on the display portions 17a and 17b, an operation method for performing the display, and the like will be described. In the figure, the display control means 30 for displaying on the display units 17a and 17b is programmed as software in a microcomputer incorporated in the controller 15 of the bath remote controller 3. The bathtub hot water temperature display control means 31 is a means for displaying the hot water temperature of the bathtub selected and set by the setting button 18a and the input selection button 19a of the bath remote controller 3 on the display unit 17a as bathtub hot water temperature information (A). is there. The hot water supply temperature display control means 32 is a means for displaying the hot water supply temperature of the shower or the like selected and set by the setting button 18a and the input selection button 19a as the hot water supply temperature information (B) and (C) on the display units 17a and 17b. Is. The display of the hot water supply temperature information (B) and (C) can be set also by the setting button 18b and the input selection button 19b of the remote controller on the kitchen side, and the hot water supply temperature display control means 32.
Is controlled and displayed on the display units 17a and 17b.

Furthermore, the heartbeat display mode selection means 33 is programmed in the display control means 30, and this heartbeat display mode selection means 33 automatically makes the display of the electrocardiographic information of the bather dependent on the electrocardiographic signal. One of the automatic display mode in which the display is started or stopped and the manual display mode in which the display is started or stopped by the operation of the bather are selectively controlled. The operation for this selection is the setting button 18a and the input selection button 1 described above.
It is performed by the operation of 9a. Specifically, when the operation switch 16a of the bath remote controller 3 is in the OFF state (power is supplied to the microcomputer), when the setting button 18a of the bath remote controller 3 is pressed, the heartbeat display mode selecting means 33 is operated to display the heartbeat. The information display mode setting screen is displayed on the display unit 17a, and one of the display modes ("automatic" or "manual") is selected by further selecting and pressing the input selection button 19a from the display screen. , The display mode is set.

In this bath water heater with an electrocardiographic information notification function, the electrocardiographic information display mode can be set only by the bath remote controller 3 installed in the bathroom. When the display mode of electric information is set, the screen when the operation switch 16b is in the OFF state is displayed on the display unit 17b of the kitchen remote controller 4.

Then, when the heartbeat display switching means 34 reaches an appropriate electrocardiographic signal of the bather in a stable state via the electrocardiogram calculation unit 9, the screen display is automatically switched. It is like this. Specifically, the screen display of the bathtub hot water temperature information (A) as shown in FIG. 2 is temporarily hidden, and then the electrocardiographic information (D) as shown in FIG. 5 is displayed. Reference numeral 35 denotes a heart rate display control means, which corresponds to the bather's heart rate per minute calculated by the heart rate calculation unit 9 based on the detected electrocardiographic signal.
The numbers corresponding to this are displayed on the display units 17a and 17b. This number is simultaneously displayed on the display section 17b of the kitchen remote controller 4 as electrocardiographic information (E).

The display area of the electrocardiographic information (D) displayed on the display section 17a of the bath remote controller 3 is as shown in FIG.
The display area is larger than the display area of the hot water supply temperature information (B) which is another display information. It is recommended to use dot matrix display for the display. This is because the display area can be enlarged or reduced by changing the number of dots. Further, the display of the electrocardiographic information is not limited to numbers, and may be displayed as a bar graph, a line graph, or the like. On the other hand, the display area of the electrocardiographic information (E) displayed on the display unit 17b of the kitchen remote controller 4 is displayed smaller than the display area of the other hot water supply temperature information (C) as shown in FIG. It is like this. If the display screen has a margin, the time may be displayed in addition to the above information.

The special display control means 36 of the display control means 30 makes a specific special display near the electrocardiographic information display on the display portions 17a and 17b based on the information calculated by the heart rate calculation unit 9. It is a thing. This display is in addition to the display of heart rate. In particular,
In accordance with the calculated heart rate, the heart mark is displayed blinking alternately in 9 steps of varying magnitudes. Further, based on the calculation result of the heart rate calculation unit 9, an arrow indicates, for example, a horizontal arrow when the heart rate does not change, a downward arrow when the heart rate is decreasing, and a heart rate increasing. If there is, an arrow that rises to the right is displayed. The calculation unit of the heart rate calculation unit 9 updates the heart rate at regular time intervals and calculates and outputs the variation state from the numerical values before and after the update. It should be noted that, instead of the arrow, characters such as “up” and “down” may be displayed to indicate the changing state.

In addition, as another special display, when the arrow indicating the fluctuation tendency of the heart rate is not displayed, that is, the state in which the proper electrocardiographic signal of the bather cannot be detected continues for a certain period of time, that effect is indicated. In order to inform the bather, the display of the heart mark may be stopped and the bar display may be performed instead of the display of the heart rate. Furthermore, immediately after the bather performed the operation to display the electrocardiographic information, the shaking of the bath surface, etc. occurred,
Since it may not be possible to detect an appropriate electrocardiographic signal in a stable state, "measurement" is displayed on the display instead of the display of the heart rate until stable calculation can be performed by the calculation unit of the heart rate calculation unit 9. The character of may be displayed.

Further, when the bar display state continues for a predetermined time, it returns to the initial screen as shown in FIG. 2, which displays the set temperature information of the bath water heater with an electrocardiographic information notification function. In the present embodiment, these display control means 30 are programmed in the microcomputer in the main body of the bath remote controller 3, but the present invention is not limited to this example, and may be provided in the controller of the bath water heater 1 with an electrocardiographic information notification function, Alternatively, it may be provided in the controller 14 of the kitchen remote controller 4. Further, it can be programmed in a microcomputer which is a calculation unit of the heart rate calculation unit 9.

Next, the display operation of the bath water heater with an electrocardiographic information notification function will be divided into the case where the electrocardiographic information display mode is set to the automatic display mode and the case where the manual display mode is set. Will be described with reference to the flowchart of FIG.

First, the setting button 18a of the bath remote controller 3
When is pressed, a display mode setting screen of heartbeat information is displayed on the display unit 17a via the heartbeat display mode selection means 33, and by pressing any one of the input selection buttons 19a, either one of the display modes (“automatic”) is displayed. Or "manual")
Is selected and the selection of the heartbeat display mode is set (step S1). This selection setting of the heartbeat display mode can be performed only when the operation switch 16a is in the off state, and other selection settings such as hot water supply temperature setting, bath temperature setting, timer reservation setting, etc. performed after the operation switch is turned on. I try to distinguish it from the operation. This is to clarify the selection.

When the heartbeat display mode is set to the automatic display mode (step S2), the operation switch 16a of the bath remote controller 3 or the operation switch 16 of the kitchen remote controller 4 is set.
When b is turned on (step S3), as shown in FIG. 2, bathtub hot water temperature information (A) and hot water supply hot water set temperature, which are preset bath hot water temperatures, are displayed on the display unit 17a of the bath remote controller 3. Hot water supply temperature information (B) is displayed, and at the same time, the display unit 17b of the kitchen remote controller 4 displays hot water supply temperature information (C) that is the hot water supply set temperature, as shown in FIG. 3 (steps S4 and S5). ).

In this state, the "auto bath" button 23a, 23b of the bath remote control 3 or the kitchen remote control 4 is pushed to perform automatic pouring to the amount of water set in the bathtub 5 or the set water level, and then the hot water is stored in the bathtub 5. The hot water is automatically kept at the bath temperature setting. Here, the "automatic heat retention state" refers to a state in which the burner of the bath water heater 1 is ignited or extinguished so as to reach the set bath hot water temperature and automatically maintains a constant hot water temperature and keeps it warm. When bathing is started in this automatic heat retention state, the electrocardiographic signal of the bather immersed in the bathtub 5 begins to be detected, and when an appropriate electrocardiographic signal is stably detected (step S
6) The display screen is automatically switched by the heartbeat display switching means 34 (step S7). That is, the bathtub hot water temperature information (A) is temporarily hidden, and instead, the electrocardiographic information (D) is displayed as shown in FIG. 5 (step S8). As the electrocardiographic information (D), a number corresponding to the heart rate per minute of the bather calculated by the heart rate calculation unit 9 based on the detected electrocardiographic signal is displayed as the heart rate display control means 35.
Is displayed on the display units 17a and 17b via.

The display area of the electrocardiographic information (D) displayed on the display section 17a of the bath remote controller 3 is as shown in FIG.
It is displayed larger than the display area of the hot water supply temperature information (B) which is another display. As a result, the bather can use the electrocardiographic information (D).
Can be visually recognized at a glance. When both the hot water supply temperature information (B) and the electrocardiographic information (D) are displayed numerically, the bather may make a mistake, but this can be removed. On the other hand, this number is simultaneously displayed on the display section 17b of the kitchen remote controller 4 as electrocardiographic information (E). As shown in FIG. 6, the display area of the electrocardiographic information (E) displayed on the display unit 17b of the kitchen remote controller 4 should be smaller than the display area of the other hot water supply temperature information (C). Has become. This is because the hot water supply temperature information (C) is displayed with priority over the electrocardiographic information (E) because the hot water supply operation is used more frequently in the kitchen.

The special display control means 36 programmed in the display control means 30 displays a specific special display on the display units 17a and 17b based on the information calculated by the heart rate calculation unit 9 ( Step S9). Specifically, the heart symbol is displayed in a blinking manner according to the calculated heart rate. Further, based on the calculation result of the heart rate calculation unit 9, an arrow indicates, for example, a horizontal arrow when the heart rate does not change, a downward arrow when the heart rate is decreasing, and a heart rate increasing. If there is, an arrow pointing up to the right is displayed. The calculation unit of the heart rate calculation unit 9 updates the heart rate at regular intervals, calculates the fluctuation state from the numerical values before and after the update, and outputs it to the special display control means 36.

In addition, as another special display, when the arrow indicating the fluctuation tendency of the heart rate is not displayed, that is, when the proper electrocardiographic signal of the bather cannot be detected for a certain period of time, that effect is indicated. In order to inform the bather, the display of the heart mark may be stopped and the bar display may be performed instead of the display of the heart rate. Furthermore, immediately after the bather performed the operation to display the electrocardiographic information, the shaking of the bath surface, etc. occurred,
Since it may not be possible to detect an appropriate electrocardiographic signal in a stable state, the display unit instead of the display of the heart rate indicates “stable” until stable calculation can be performed by the calculation unit of the heart rate calculation unit 9. You may make it display the character "in measurement" etc.

When the bather leaves the bathtub 5, the electrocardiographic signal is not detected (step S10). Therefore, the electrocardiographic display is automatically switched by the heartbeat display switching means 34 via the heartbeat rate calculation unit 9. (Step S11), the display returns to the initial screen for setting and displaying the bath temperature and the hot water supply temperature as shown in FIG. 2 (Step S12, Step S1).
3).

On the other hand, in FIG. 8, when the electrocardiographic information display mode is set to the manual display mode (step S14), the operation switches 16a and 16b are turned on (step S15), FIG. As shown in FIG. 3, preset bath temperature display and hot water supply temperature display are performed (step S16, step S17). When a bather who has been immersed in the bathtub wants to display electrocardiographic information such as heart rate, he or she presses the setting button 18a of the bath remote controller 3 to display a display selection screen on the display unit 17a, and then an input selection button 19a. When the display selection “Yes” is selected by (step S18), the screen is switched to the electrocardiographic information display screen (step S19). If a heartbeat is detected (step S2
0), the heart rate is displayed as described above (step S21).
Also, a special display is made (step S22). The setting button 18a is displayed while the display selection screen is displayed.
By sequentially pressing, it is possible to sequentially switch to setting screens such as "plenty / slimy", "bath temperature", and "bath hot water amount".

In the manual display mode, the display unit 17a,
When the display of the electrocardiographic information is desired to be stopped while the electrocardiographic information is being displayed on 17b, the selection screen is displayed by pressing the setting button 18a, and subsequently the display selection is made by the input selection button 19a "No". When is selected (step S23), the initial screen as shown in FIGS. 2 and 3 is switched to. Then, the operation switches 16a, 16
When b is turned off (step S24), the bath and hot water supply operations are stopped.

Further, according to the present invention, the electrocardiographic information is automatically notified when the bath water by the bath water heater 1 is in the automatic heat retaining state. This will be specifically described with reference to the flowchart of FIG. Those common to FIG. 8 are given the same numbers and used. After turning on the operation switches 16a and 16b (step S3), the automatic bath buttons 23a and 23
Press b (step S25) to start automatic pouring from the bath water heater 1 into the bathtub 5 (step S26). When the pouring is completed (step S27), the automatic heat retention state described above is subsequently entered (step S28).

When the electrocardiographic signal is detected in this state (step S6), the display is switched via the heart rate calculation unit 9 and the heartbeat display switching means 34 (step S7). This switching is displayed as electrocardiographic information such as heart rate on the display unit 17a of the bath remote controller 3 instead of bathtub hot water information (step S8).
The changeover is automatically performed, and the bather does not need to operate any switches for displaying the heartbeat.
Shows the heart rate. At the same time, the special display described above is made (step S9). In addition, bath automatic button 23
When a and 23b are pressed again to end the automatic heat retention (step S29), the display of the heartbeat is switched (step S29).
30), the original screen may be returned.

The above-described embodiment shows a preferred embodiment of the present invention, and the present invention is not limited to this, and various design changes can be made within the range. For example, in the present embodiment, the user is made to select the automatic display mode and the manual display mode, but the present invention is not limited to this, and it is limited to either the automatic display mode or the manual display mode. Is also possible.
