It is a flowchart which shows the display control which a water heater performs when operating the bathroom heating function. It is a figure which shows the example of a display which expressed how much hot water which came out of the water heater reaches | attains a shower head with a display color.

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

  FIG. 1 shows a configuration example of a water heater system 2 as an apparatus in which a related information display method according to the present invention is implemented. The water heater system 2 includes a water heater 10 and a bathroom heater 20 connected thereto. A remote controller 30 installed in a kitchen, bathroom, or the like is connected to the water heater 10 by wiring 6.

  The water heater 10 heats the water supply and discharges water to a predetermined tap 3 (for example, a shower in a bathroom or a kitchen faucet), a function of pouring (hot water) into the bathtub 4, and hot water in the bathtub 4 It has a function to catch up. In addition, hot water of a set temperature is automatically filled in the bathtub 4 so as to reach a set water level, and after completion of the hot water filling, the set water level and set temperature are maintained for a predetermined time (for example, 4 hours). It has a function of automatic bath operation for retreating.

  The water heater 10 has a function of heating the bathroom using the bathroom heater 20 as a heat dissipation unit. The bathroom heater 20 includes a heat exchanger 21 and a fan 22 that blows air into the bathroom via the heat exchanger 21. The water heater 10 circulates the heat medium fluid heated by itself while operating the fan 22 of the bathroom heater 20 to the bathroom heating circuit 24 including the heat exchanger 21 of the bathroom heater 20 to warm the bathroom. It has a bathroom heating function that heats the bathroom by sending out wind.

  The remote controller (remote controller) 30 performs a function of receiving an instruction regarding the operation of the water heater 10 (and the bathroom heater 20) from a user, a function of displaying the operation state of the water heater 10 and the bathroom heater 20, and the like. For example, you can accept instructions such as changing the hot water supply temperature setting, changing the bath temperature setting, setting the time for automatic hot water filling in the bath, turning on / off the bath automatically, and turning on / off the bathroom heating function. And information about errors and error information. Here, the bathroom heating function operates to automatically stop after being operated for a preset time (for example, 30 minutes) when an ON operation is received.

  The display unit 31 of the remote controller 30 is configured by a liquid crystal display capable of full color display.

  The water heater 10 includes a control board 11 for overall control of the operation of the water heater 10.

  FIG. 2 is a diagram illustrating a configuration of the control board 11 and peripheral devices connected to the control board 11. The control board 11 includes a control unit 12 mainly composed of a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and a time measuring unit 13 that measures the passage of time. An information acquisition unit 14 is provided. The related information acquisition unit 14 collects information (related information) related to a related element that affects a predetermined parameter related to the display color.

  For example, if the predetermined function is a bathroom heating function and the predetermined parameter is the bathroom temperature, the related elements are the elements that affect the bathroom temperature, such as the season, the opening / closing state of the bathroom window, the ventilation fan on / off, etc. It is. Seasonal information may be obtained from the current date, or may be obtained, for example, by accessing a weather station site or a site providing weather information through the Internet. Moreover, the acquisition method of the information regarding related elements, such as a season, may be a manual acquisition such as a user setting in addition to an automatic acquisition.

  The control unit 12 of the control board 11 is connected to the temperature sensor 7 for detecting the temperature in the bathroom, the bathroom heater 20 and the remote controller 30 described above. The controller 12 is connected to a water heater body 16 (various components such as an electromagnetic valve, a sensor, and an igniter included in the water heater 10).

  When an operation such as the start of automatic bath operation or the on / off of the bathroom heating function is received from the user through the remote controller 30, a command indicating the operation content is transmitted from the remote controller 30 to the control unit 12 of the control board 11, and the control is performed accordingly. The part 12 controls the corresponding part of the water heater body part 16 and the bathroom heater 20. Further, the control unit 12 generates various display information to be displayed on the remote controller 30, and transmits the display information to the remote controller 30 for display.

  When the control unit 12 of the water heater 10 performs a bathroom heating function, a reheating function, or the like, the remote controller 30 displays an elapsed time (operation time) after the function starts operating or a remaining time until the operation is stopped. The display unit 31 has a function of changing the display color of a predetermined portion of the display unit 31 according to the value of a predetermined parameter related to the function (related information display function by color). The predetermined parameter is preferably a parameter whose value changes in response to the function.

  For example, when the bathroom heating function is turned on, the remaining time until the function is automatically turned off is displayed as a number on the display unit 31 of the remote controller 30 and is updated as time passes. The color of this number displaying is automatically and sequentially changed according to the temperature of the bathroom.

  FIG. 3 illustrates the transition of the display state of the remaining time after the bathroom heating function is turned on until this function is automatically turned off. Immediately after the bathroom heating function is turned on, the temperature in the bathroom is low, so the remaining time is displayed as “30 minutes” in a cool color. Thereafter, the numerical value of the remaining time gradually decreases as “25”, “20”, “15”. And since the temperature in a bathroom rises gradually by the effect | action of heating, the display color of the numerical value of remaining time is changed gradually to warm color.

  Here, a unique color number is assigned to each displayable color. The coldest color number is 60, and the color number decreases as the color approaches the warm color, and the color number of the warmest color is 0.

  For example, normally, when the remaining time is 15 minutes, the remaining time is displayed in the color of color number 30. However, today, if the remaining time is displayed in the color of color number 45 at the time when the remaining time is 15 minutes, the user who has seen this intuitively notices that the bathroom does not warm up easily. Then, the user checks whether there is a bathroom window, checks whether the bathroom exhaust fan is turned on, and checks whether warm air is emitted from the bathroom heater 20. You can take actions such as

  Further, for example, as usual, the remaining time is 15 minutes, and the remaining time is displayed in the color of color number 30. However, because today is a day when grandmother takes a bath, in order to prevent heat shock, it is a day when the bathroom between the bathroom and the dressing room must be opened and the dressing room heating must be performed using the bathroom heating function. It is intuitively noticed that you forgot to open the door between the bathroom and the dressing room. Then, the user can take an action such as checking whether or not the door between the bathroom and the dressing room is closed.

  FIG. 3 shows the transition of the display state when the bathroom heating function is operated in winter and when the ventilation fan is off.

  FIG. 4 shows the transition of the display state when the bathroom heating function is operated in the state where the ventilation fan is off in the spring. Compared to the winter season (FIG. 3), it can be easily seen from the display color of the remaining time and its change that the temperature in the bathroom is rising in a short time in spring.

  FIG. 5 shows transition of the display state when the bathroom heating function is operated in the winter when the ventilation fan is on. Compared to FIG. 3, it can be seen from the display color of the remaining time and the change state thereof that the temperature in the bathroom does not increase easily.

  In this way, since the display color is changed according to the temperature of the bathroom together with the display of the elapsed time after the bathroom heating function is activated and the remaining time until the operation is stopped, the user can change the elapsed time and the remaining time and the time. From the correspondence with the display color, it is possible to intuitively notice that the bathroom is warmed more slowly than usual, and actions such as checking the cause can be taken.

  In addition, the following modifications may be added.

<Change the correspondence between temperature and display color according to the state of related elements>
(1) Change the correspondence between temperature and display color depending on the season.
The temperature at which a person feels appropriate or warm varies depending on the season. Therefore, the correspondence between temperature and display color is changed according to the season. FIG. 6 is a temperature / display color correspondence table showing a correspondence relationship between a display color (color number) and an applicable temperature range using the display color, and is an example of a table for winter and a table for seasons other than winter. Show. By switching the temperature / display color correspondence table to be referred to according to the season, the correspondence between the bathroom temperature and the display color can be changed, so that the relationship between the temperature that the person feels warm and the display color does not shift. it can.

(2) Change the correspondence between the temperature and the display color according to the situation of the environment (bathroom) such as a ventilation fan that affects the temperature.
For example, when the ventilation fan is on, the temperature tends to be difficult to rise. Therefore, the display color is shifted to a warm color system at a lower temperature than when the ventilation fan is off. Whether or not a device that affects the environmental temperature such as a ventilation fan is operating may be recognized based on information obtained through communication with the device, or may be manually input. As in the case of the season, a temperature / display color correspondence table corresponding to on / off of the ventilation fan is prepared, and the temperature / display color correspondence table to be referred to is switched by turning on / off the ventilation fan. When dealing with both the seasonal and ventilating fan on / off related elements, a temperature / display color correspondence table corresponding to each of these combinations is prepared.

<Regarding where the display color is changed>
In addition to changing the color of the numerical value (object) that displays the operating time and the remaining time until shutdown, changing the color of the background color of the numerical value or any object (mark or character) displayed with the numerical value Good. In the case of a character such as an animal, the movement and facial expression may be further changed in addition to the display color.

<Use gradation>
By changing the display color gradually or stepwise from one of the specified locations (numerical values indicating the operation time or remaining time until operation stop, its background color, object, etc.) to change the display color, etc. It represents the state of change (the magnitude of the change) of the predetermined parameter value over time. For example, a gradation is given to the display color of a numerical value indicating the operation time or the remaining time until the operation stop. It is displayed so that it can be seen at a glance whether the value of the predetermined parameter is changing slowly or greatly changing in a short time due to the magnitude of the tone difference of the numerical value given gradation.

  For example, when displaying the operation time from the start of heating, the lower end of the numerical value is the display color corresponding to the measured value of the temperature five minutes ago, and the central portion of the numerical value is the display color corresponding to the measured value of the current temperature The upper end portion of the numerical value is expressed as a display color corresponding to the predicted value of the temperature after 5 minutes, and the temporal change in temperature is expressed by the difference in display color depending on the location in one number. In addition to changing the color smoothly using gradation, for example, the numerical value is divided into three areas, upper, middle, and lower, and the same color is used in each area, and the display color is clearly switched at the boundary of the area It may be a change.

  FIG. 7 is a flowchart showing processing related to display control performed by the water heater 10 when the bathroom heating function is operating. This process is executed when an operation for turning on the bathroom heating function is received from the remote controller 30. When the bathroom heating function is turned on, the bathroom heating operation is performed for 30 minutes and then automatically stops.

  When the water heater 10 receives an operation for turning on the heating function, the water heater 10 starts a bathroom heating operation (step S101). Specifically, the fan 22 of the bathroom heater 20 is turned on, the heat medium fluid is circulated by the circulation pump in the bathroom heating circuit 24, and the burner of the water heater 10 is burned to heat the heat exchanger in the water heater 10. The heating medium fluid is heated at. Thereby, warm air is sent out from the bathroom heater 20 to the bathroom.

  Simultaneously with starting the bathroom heating operation, the timer 13 is operated to start a subtraction timer for 30 minutes (step S102). In addition, the related information acquisition unit 14 acquires information indicating the state of a predetermined related element that affects the temperature of the bathroom, such as seasonal information and on / off of the ventilation fan (step S103). Then, a temperature / display color correspondence table corresponding to the acquired related information (season, on / off of the ventilation fan, etc.) is selected (step S103).

  The current temperature of the bathroom is acquired by the temperature sensor 7 (step S105), and the display color (color number) is determined by referring to the temperature / display color correspondence table selected in step S103 (step S106). . The current value (remaining time) of the subtraction timer is read, and the value is displayed on the remote controller 30 in the display color determined in step S106 (step S107). Specifically, a command indicating the display content is transmitted to the remote controller 30, and the remote controller 30 that has received the command displays according to the command.

  Thereafter, it is checked whether or not the subtraction timer has expired (step S108). If the timer has not expired (step S108; No), the process returns to step S103 to continue the processing. When the related information is collected by returning to step S103, the value that is first examined for the information that does not change in a short time, such as the season, may be used as it is. For related elements that may change during the process, such as on / off of a ventilation fan, the status is acquired anew.

  When the subtraction timer expires (step S108; Yes), the bathroom heating operation is stopped (step S109), and then the remaining time “0” until the operation is stopped is displayed for a predetermined time in the display color corresponding to the current room temperature. After that, the display is turned off (step S110), and this process ends.

  In the description of the bathroom heating function, an example in which the related parameter is the bathroom temperature is shown, but the parameter whose value is changed by the effect of heating includes humidity in addition to temperature.

  The application of the present invention is not limited to the bathroom heating function described so far. For example, any function such as a ventilation function or an air purification function may be used. Further, in the case of the water heater 10, a reheating function or the like may be used. The operation time of the reheating function is displayed as a numerical value, and the hot water temperature is displayed in a display color.

  For example, when chasing up the remaining hot water of yesterday, if there is enough remaining hot water, it will rise to an appropriate temperature in about 30 minutes after starting chasing. In this case, the operating time display color gradually changes from cold to warm over 30 minutes.

  When the amount of remaining hot water is small, the temperature rises in a shorter time than usual, so that the display color of the operation time changes to a warm color earlier than usual. The user can intuitively recognize that the amount of hot water is low simply by seeing that the display color of the operating time has changed to a warmer color sooner than usual. For example, it is necessary to add hot water after chasing. Can recognize and deal with it.

  A temperature sensor is attached to the bathroom remote control, etc. so that the bathroom temperature can be detected, and the time display color after taking out the shower is assumed by the bathroom remote control etc. You may make it change a display color according to the bathroom temperature to detect.

  In addition, you may use a display color as an expression method of drying and ventilation information from information, such as bathroom temperature and humidity. Moreover, you may make it represent the sanitary state of air with a display color from the information of inhalation air.

  The parameter associated with the display color may be a parameter related to the function to be activated, and may not necessarily be a parameter whose value is changed by the function of the function to be activated. For example, when using a bathroom heating function when performing automatic hot water filling of a bath, the remaining time until the bathroom heating function is stopped may be displayed as a numerical value, and the state of the hot water filling (water level, etc.) may be represented by a display color. it can. Alternatively, the remaining time until hot water filling is completed may be displayed as a numerical value, and the temperature of the bathroom being heated may be expressed by a display color by the bathroom heating function.

<Modification>
When a shower is taken out, hot water of a set temperature comes out from the water heater 10 relatively quickly, but when the piping path to reach the shower head is long, hot water does not come out from the shower head. Therefore, the remote controller 30 installed in the bathroom displays the set temperature of the shower as a numerical value and expresses how much hot water will come out of the shower head by the display color.

  For example, when the water heater 10 is installed, the capacity (pipe capacity) from the water heater 10 to the shower head is measured. Then, when the tap is opened and the hot water is discharged from the shower head, the total water flow amount after the shower faucet is opened is measured, and the measured total water flow amount / pipe capacity = reach rate is obtained. The display color such as the set temperature is changed according to. When the arrival rate is close to 0, it is displayed in a cool color, and as the arrival rate approaches 1, it is changed to a warm color.

  An example is shown in FIG. The display color of the set temperature “40 ° C.” sequentially changes corresponding to the arrival rate. The user can know when the hot water of the set temperature comes out from the shower head by watching the change in the display color of the set temperature, without touching and checking the hot water coming out of the shower head by hand. You can bathe in hot water that is at the right temperature.

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to that shown in the embodiment, and there are changes and additions within the scope of the present invention. Are also included in the present invention.

  In the embodiment, the operation time of the predetermined function or the time until the operation is stopped is displayed as a numerical value, but other than the numerical value, for example, it may be expressed by a bar graph length or the like like a level meter, and may be arbitrary.

  In the embodiment, the hot water heater system 2 has been described as an example of an apparatus in which the related information display method according to the present invention is implemented, but the application of the present invention is not limited to this. For example, the related information display method according to the present invention may be implemented by an air conditioner such as an air conditioner, or a cooking utensil such as a gas stove or oven. For example, when the oven is preheated, the remaining time until completion of preheating may be displayed as a numerical value, and the internal temperature may be expressed in a display color. An apparatus for executing the related information display method according to the present invention is also included in the present invention. Furthermore, the function unit such as heating is separated and the elapsed time of the function unit operating or the remaining time until the operation stop is displayed on the display unit, and according to the value of a predetermined parameter related to the function of the function unit Thus, an information display device that changes the display color of a predetermined portion of the display unit or a program thereof may be used.
