可能になっている。As is well known, hot water supply systems are installed in facilities related to water supply such as heating, washbasins, and bathrooms, and this system includes temperature display means and time display means. The temperature display means is useful for confirming whether the hot water temperature is appropriate. The time display means is very useful as a time signal when the time is restricted, rather than simply knowing the current time. As this kind of display means, it is often found that a display for clock (time) display and a display for temperature display are separately provided. In the case where the two indicators are provided as described above, it is possible to know the time and the temperature at the same time, which is convenient, but in practice, it is easy to cause a trouble. For example, in the case of a bathroom or bath when the next schedule is imminent in time, it is easier to pay attention to the clock indicator rather than the temperature indicator, so the abnormal hot water temperature ( (High temperature) is overlooked and burns occur. In addition, if two indicators are provided, cost increase cannot be avoided. As the display means other than the above, a temperature sensor, a dual-purpose display for both temperature display and clock display, and a display device including an integrated circuit are used, and the temperature displayed on the dual-purpose display (the temperature detected by the temperature sensor) and It is considered to switch the time every predetermined seconds. By the way, JP-A-56-1685
The display means disclosed in Japanese Patent Publication No. 86 is also based on such an idea, and particularly in this known technique, it is possible to switch to temperature display by interruption even during time display.

既述の事態を知ることもある。しかし、この割り込み温

表示が実行されるので煩わしく、これが異常温度の報知
を混乱させる。In the case of the method of alternately repeating the clock display and the temperature display for every predetermined seconds on one display like the above-mentioned means, the temperature of the hot water rises abnormally due to equipment trouble, temperature setting error, etc. Even if it is going on, it is not possible to accurately notify such a situation. That is, even if the hot water temperature reaches a dangerous range while the clock is displayed, the display displays the time until a predetermined time has elapsed, and thereafter, the time and the temperature are alternately displayed without changing from normal time. . On the other hand, in the case of the above-mentioned known technique, the temperature is interrupt-displayed when the temperature of the measurement object changes even during the clock display, so that the above-described situation may be known in the interrupt display state. However, this interrupt temperature display method is continued for a predetermined time, and then
Since the time display is switched to the clock display, it is impossible to know whether the temperature change at this time is dangerous or transient. In addition, the temperature interruption display is executed even when the temperature changes in the normal temperature range, which is troublesome, and this confuses the notification of the abnormal temperature.
本発明はこのような技術的課題に鑑み、単に温度と時
刻とを表示するだけでなく、異常温度が生じた場合には
温度表示を優先させて危険な事態やその他の不都合を回
避することのできる温度・時刻の交互表示法を提供しよ
うとするものである。In view of such a technical problem, the present invention not only displays the temperature and time, but also prioritizes the temperature display when an abnormal temperature occurs to avoid a dangerous situation or other inconvenience. It is intended to provide an alternate display method of temperature and time that can be displayed.

表示状態に切り替えることを特徴とする。The present invention is characterized by the following means for solving the problems in order to achieve the intended purpose. That is, using a display device in which a temperature sensor for temperature detection is connected to the input side of a large-scale integrated circuit, and a dual-purpose display for both temperature display and clock display is connected to the output side of the large-scale integrated circuit, respectively. The temperature sensor is placed in the temperature measurement area, and the output of the large-scale integrated circuit to which the temperature measurement value is input from the temperature sensor is applied to the dual-purpose display to display the temperature in the temperature measurement area on the dual-purpose display. In the alternative method of displaying the time on the dual-purpose display, when the dual-use display is in the time display state, the temperature of the temperature measurement area is set via the temperature sensor at every t 1 for a predetermined period of time. The temperature measurement value is input to the large-scale integrated circuit after being measured, and when the temperature difference T 1 of a predetermined value or more is detected in the measured temperature of t 1 for each second, the temperature measurement value is also used via the large-scale integrated circuit. Set the display to the temperature display state Ri replace it,
When the dual-purpose display is in the temperature display state, the temperature of the temperature measurement area is measured through the temperature sensor for t 2 for a predetermined time and these temperature measurement values are input to the large scale integrated circuit. When the temperature change at t 2 during the second is less than the predetermined temperature T 2 , the dual-purpose display is switched to the time display state via the large-scale integrated circuit.

In the display state, the temperature of the temperature measurement region is measured by the temperature sensor, for example, every 2 seconds. If a change of ± 1.0 ° C. or more occurs in the temperature measurement value at this time, the dual-purpose display is switched to the temperature display state by the large-scale integrated circuit and displays the temperature measurement value every one second, for example. In such a temperature display state, for example, if the temperature measurement value changes less than ± 1.0 ° C even after 8 seconds have passed, the large-scale integrated circuit switches the dual-purpose display unit to the clock display state based on this and measures the temperature. If the value does not change by ± 1.0 ° C or more, the above temperature display state is maintained.

Is input to the large-scale integrated circuit LSI, and the large-scale integrated circuit LSI is input to the dual-purpose display 2. When a temperature difference of T 1 (eg ± 1.0 ° C) or more is detected during temperature measurement in this clock display state, the large-scale integrated circuit LSI outputs an electric signal of a predetermined level to the dual-purpose display unit 2. , Dual display 2 in Fig. 2, left 1
The second clock display state is switched to the second left temperature display state in FIG. If the hot water temperature of the hot water mixer 4c does not change significantly for t 2 seconds (eg, 8 seconds) and remains below the predetermined temperature T 2 after such switching, the temperature sensor 3 → large-scale integrated circuit LSI → The dual display 2 switches its temperature display state to the clock display state by an electric signal of a predetermined level flowing like the dual display 2. If a temperature change of T 2 or more occurs within t 2 seconds, the dual display 2 displays the temperature as it is. Furthermore, after a temperature change of T 2 or more, t 2
Even when the temperature stabilizes only for a second, as in the above, the temperature indicator 3 → large-scale integrated circuit LSI → the dual-purpose display 2 causes the dual-purpose display 2 to display its temperature display state by the electric signal of a predetermined level flowing. Switch to the display state. After the dual-use display 2 returns to the time display state, the temperature is measured again every t 1 seconds, and the time display state of the dual-use display 2 shows the temperature difference of the temperature difference T 1 or more as shown in the right side of FIG. The display switches to the temperature display state.
