Description

本考案は、深夜電力を利用した電気温水器に関するものである。 The present invention relates to an electric water heater using midnight electricity.

従来の電気温水器は、廉価な深夜電力を利用して夜間に沸き上げるようにするため、直流電圧および電池で駆動する時計により、夜間、昼間を判断し、通電電力の開閉を行っている。 In the conventional electric water heater, in order to use inexpensive midnight electric power to boil at night, a clock driven by a DC voltage and a battery is used to determine nighttime and daytime to open and close the energized electric power.

本考案が解決しようとする課題は、停電による電力遮断や長期外出に際しての電力切断により、時計を駆動する電池が放電して時計が停止することを防止し、さらにこの時計が停止した場合でも正常動作に復帰できるような電気温水器を提供することにある。 The problem to be solved by the present invention is to prevent the battery that drives the watch from being discharged and the watch from stopping due to power interruption due to a power failure or power disconnection when going out for a long period of time, and even if the watch is stopped, it is normal. The purpose is to provide an electric water heater that can return to operation.

本考案は、昼間に比べて廉価な深夜電力を利用する電気温水器において、昼夜を識別するために設けられた時計のために使用する電源に太陽電池を接続し、時計を時刻較正用の電波受信装置と接続し、昼夜の判別に、太陽電池あるいは別個に設けた照度計を使用することを特徴とする電気温水器である。 The present invention is an electric water heater that uses midnight power, which is cheaper than daytime, by connecting a solar cell to the power supply used for the clock provided to identify day and night, and making the clock a radio wave for time calibration. It is an electric water heater that is connected to a receiving device and uses a solar cell or a separately installed luminometer to distinguish between day and night.

本考案の電気温水器によれば、停電あるいは外出時の意図的な電力遮断により、電気温水器の昼夜判別手段である時計が停止、あるいはこの時計の停電時代替電源が一定時間後に停止しても、太陽電池により時計電源を駆動することができる。また、電源復帰時に、時計の時刻がずれていても、時刻較正電波を受信する装置により、時刻を正しく修正できる。また、時刻較正電波の受信障害により電波時計受信回路が正しく動作しない場合も、太陽電池あるいは別途に設けた照度計により昼夜を判別し、廉価な夜間電力を利用して、電気温水器の沸き上げをすることができる。 According to the electric water heater of the present invention, the clock, which is a means for discriminating day and night of the electric water heater, is stopped due to a power failure or intentional power interruption when going out, or the alternative power supply for the clock is stopped after a certain period of time. However, the clock power supply can be driven by a solar cell. Further, even if the time of the clock is deviated when the power is restored, the time can be corrected correctly by the device that receives the time calibration radio wave. In addition, even if the radio-controlled clock reception circuit does not operate correctly due to a reception failure of the time-calibrated radio wave, the day and night are discriminated by a solar cell or a separately installed illuminance meter, and the electric water heater is boiled using inexpensive nighttime power. Can be done.

本考案の一実施例の電気温水器の従来部分を示す構成図である。電気温水器は、水槽1にヒータ2が設置され、開閉装置3によりヒータ電力が入切りされる。電気温水器の電力は一般に単相3線式200V電源4が使用される。ヒータ2の温度情報は、通電時間算出部7において温度設定値と比較され、夜間沸き上げ動作開始決定部6において、現在時刻を刻時する時計8および経過時間を計測するタイマ9の情報をもとに、ヒータ制御部5を駆動する。時計8は停電時の補助電源として二次電池即ち充電型電池10と接続されている。この電池は、200V電源4から装置各部を駆動する電源を作るための電源部11に接続されている。It is a block diagram which shows the conventional part of the electric water heater of one Example of this invention. In the electric water heater, the heater 2 is installed in the water tank 1, and the heater power is turned on and off by the switchgear 3. A single-phase three-wire 200V power supply 4 is generally used as the electric power of the electric water heater. The temperature information of the heater 2 is compared with the temperature set value in the energization time calculation unit 7, and the information of the clock 8 for ticking the current time and the timer 9 for measuring the elapsed time is also included in the night boiling operation start determination unit 6. Then, the heater control unit 5 is driven. The clock 8 is connected to a secondary battery, that is, a rechargeable battery 10 as an auxiliary power source in the event of a power failure. This battery is connected to a power supply unit 11 for producing a power source for driving each unit of the device from the 200V power supply 4.

図2は、本考案の一実施例の電気温水器の構成図である。
この図に示すように、本実施例の電気温水器は、時計8に接続された電池10に、太陽電池12を接続する。さらに、時計8の時刻修正部13に、時刻情報を受信する電波時計受信部14を接続する。さらに、時刻修正部13に、太陽電池12あるいは、屋外や太陽を感知できる明るさのある場所に設けた照度センサ15を接続したものである。
~構成・作用効果~
図2に示すように、電源部11に供給される200V(4)が遮断されると、電池10が時計8を継続して駆動し、正しく刻時するが、一定時間例えば2~3日後には、電池10が放電して時計8が停止する。この後、電源200Vが復帰したとき、時計の時刻は現在時刻とは異なるので、昼夜の判断を誤り、昼間に沸き上げをすることがある。この場合、高価な昼間の電気料金が適用され、使用者は損害を被る。しかし、時計8を補助駆動する電池10に太陽電池12を接続しているので、電池10が放電してしまうことがなく、昼夜の判断を誤ることがなくなる。
~具体例・変形例~
図2に示すように、時計8には、時刻修正部13を設ける。時計8は、ここには図示しないが、例えば水晶発振回路と分周回路、時刻表示回路からなり、分周回路の設定により時刻の修正ができる。時刻修正部13は分周回路の再設定動作を行う。電波時計受信部14は、ここには図示しないが、フェライト棒に銅線を巻いたアンテナにより、長波40kHzあるいは60kHzで送信される時刻較正電波を受信し、時刻情報を得る回路で、電波時計として市販されているものと同一である。時計8は一定時刻例えば、1日に1回、電波時計受信部14の時刻で修正する。これにより、時計は正確に現在時刻を刻み、昼夜を誤ることはない。
~具体例・変形例2~
図2に示すように、時計8の時刻修正部13には、照度センサ15を接続する。照度センサ15のかわりに、電池10を充電するための太陽電池12でもよい。照度センサ15あるいは、太陽電池12は、図3に示すように、朝23から夕25の間はセンサ出力22の電圧が24~26のように高く、夕5から朝7までは26~28のように低い。また、朝24は、出力電圧が上昇し、夕26では、減少するので、朝と夕が区別できる。図2の時刻修正部13において、朝24であれば、例えば7時に、夕26であれば19時に修正する。また、時計を修正するかわりに、照度センサ26の出力をそのまま昼夜信号としてもよい。
FIG. 2 is a block diagram of an electric water heater according to an embodiment of the present invention.
As shown in this figure, in the electric water heater of this embodiment, the solar cell 12 is connected to the battery 10 connected to the clock 8. Further, a radio clock receiving unit 14 for receiving time information is connected to the time adjusting unit 13 of the clock 8. Further, the time adjustment unit 13 is connected to the solar cell 12 or the illuminance sensor 15 provided outdoors or in a bright place where the sun can be detected.
~ Composition / Action ~
As shown in FIG. 2, when the 200V (4) supplied to the power supply unit 11 is cut off, the battery 10 continuously drives the clock 8 and ticks correctly, but after a certain period of time, for example, 2 to 3 days. The battery 10 is discharged and the clock 8 is stopped. After that, when the power supply 200V is restored, the time on the clock is different from the current time, so that the judgment of day and night may be mistaken and the clock may boil in the daytime. In this case, expensive daytime electricity charges are applied and the user suffers damage. However, since the solar cell 12 is connected to the battery 10 that assists the clock 8, the battery 10 does not discharge, and the day and night determination is not mistaken.
-Specific examples / transformation examples-
As shown in FIG. 2, the clock 8 is provided with a time adjustment unit 13. Although not shown here, the clock 8 includes, for example, a crystal oscillator circuit, a frequency dividing circuit, and a time display circuit, and the time can be adjusted by setting the frequency dividing circuit. The time correction unit 13 resets the frequency dividing circuit. Although not shown here, the radio-controlled clock receiver 14 is a circuit that receives time-calibrated radio waves transmitted at a long wave of 40 kHz or 60 kHz by an antenna in which a copper wire is wound around a ferrite rod to obtain time information, and serves as a radio-controlled clock. It is the same as the one on the market. The clock 8 is adjusted at a fixed time, for example, once a day at the time of the radio-controlled clock receiving unit 14. As a result, the clock keeps the current time accurately and does not mistake day and night.
-Specific example / Modification example 2-
As shown in FIG. 2, an illuminance sensor 15 is connected to the time adjustment unit 13 of the clock 8. Instead of the illuminance sensor 15, a solar cell 12 for charging the battery 10 may be used. As shown in FIG. 3, the illuminance sensor 15 or the solar cell 12 has a high voltage of the sensor output 22 as high as 24 to 26 from morning 23 to evening 25, and 26 to 28 from evening 5 to morning 7. As low as. Further, since the output voltage rises in the morning 24 and decreases in the evening 26, the morning and the evening can be distinguished. In the time correction unit 13 of FIG. 2, if it is 24 in the morning, it is corrected at 7:00, and if it is 26 in the evening, it is corrected at 19:00. Further, instead of modifying the clock, the output of the illuminance sensor 26 may be used as a day / night signal as it is.
