【０００６】
【発明の実施の形態】
請求項１に記載した発明は、外部からの水を浄化するあるいは水質を良化する浄水器と、前記浄水器からの水を吐出する開口部である浄水吐出口と、加熱手段を有し前記浄水器からの水を貯め加熱する貯湯容器と、前記貯湯容器の湯を出湯する開口部である出湯口と、前記浄水器からの水の流れを前記浄水吐出口側と前記貯湯容器側に切り換える切り換え弁と、前記貯湯容器内の湯を前記出湯口から器体外に吐出する電動ポンプと、前記貯湯容器内の湯の温度を検出する温度検出手段と、前記貯湯容器内の水位を検出する水位検出手段を備え、前記水位検出手段の検出結果が満水状態でなく、温度検出手段の検出結果が所定温度以上で、所定量の水が浄水器から貯湯容器に給水されたとき、前記加熱手段を所定時間駆動停止して前記所定温度未満になるよう制御する浄水器付き電気湯沸かし器とすることにより、貯湯容器内の湯の温度が高いときに、適量の水を浄水器から供給して極端に貯湯容器内の湯の温度が低下しないようにすることができ、また、給水した後で、さらに給水されて湯温が限度を超えて低下するのを防止することができる。
【０００７】
請求項２に記載した発明は、請求項１の構成で、特に、外部から浄水器への給水を制限する給水弁と、前記給水弁の制御を行う給水制御手段を備え、前記給水制御手段は前記給水弁が給水を制限して以降、切り換え弁を切り換えるようにすることで、外部からの給水が高圧であっても、切り換え弁が安定して切り替わるようにする浄水器付き電気湯沸かし器を実現したものである。
【０００８】
【実施例】
以下、本発明の実施例について図面を用いて説明する。
【０００９】
（参考例１）
図１は本発明の参考例の構成を示すブロック図である。１３は水道蛇口１０からの水を給水したり止水したりする給水弁である。１は活性炭や中空糸フィルタからなる浄水器で、一方は給水弁１３に接続され、他方は切り換え弁３に接続されている。２は貯湯容器でヒーター４により貯湯容器内の水を加熱する。３は浄水器１から浄水の流れを浄水吐出口１１側と貯湯容器２側へ切り換える切り換え弁である。５は貯湯容器２内のお湯を出湯口１２に吐出するための電動ポンプである。６は貯湯容器２内のお湯の温度を検出するための温度検出手段である。１４は貯湯容器２内のお湯を排出するお湯排水経路で、お湯排水弁１５の開閉で調節する。７は貯湯容器２内で発生した蒸気を器体外に出す蒸気排出経路である。８は蒸気排出経路７を通る蒸気温度を検出するための蒸気温度検出手段である。
【００１０】
以下本参考例の動作について説明する。まず、浄水された水を利用したい場合、図示していない浄水スイッチを押すことにより、切り換え弁３を浄水器１から得た浄水を浄水吐出口１１側へ流れるように切り換える。そして、給水弁１４を開くことにより、この水路で水道蛇口１０からの原水は浄水器１を通って浄水されて浄水吐出口１１から吐出される。
【００１１】
次に、浄水されたお湯を利用したい場合、貯湯容器２に給水するには切り換え弁３を浄水器１から得た浄水を貯湯容器２側へ流れるように切り換え、給水弁を開くことによって出来る。貯湯容器２に蓄えられた浄水はヒーター４により加熱される。そして、図示していない出湯スイッチを押すと押している間だけ電動ポンプ５が駆動して貯湯容器２内のお湯を出湯口１２より吐出する。
【００１２】
次に、温度検出手段６と蒸気温度検出手段８を用いた沸騰検知について説明をする。ヒーター４で加熱すると貯湯容器２内の水が加熱され温度が上昇する。この時、温度検出手段６によって得られる温度情報と実際のお湯の温度は、少量のお湯の場合では温度検出手段６の追従性は悪くなり得られる温度情報は低いものとなる。よって、お湯が１００℃になっても温度検出手段６より得られる温度情報が１００℃になるまでお湯を加熱し続ける。これにより、蒸気が多く器体外に出る。本発明ではこのように少量のお湯の場合でも蒸気排出経路７内に蒸気温度検出手段８を備えて、蒸気を検出することで沸騰状態と判断してヒーター４の加熱を停止するので器体外に蒸気が出ることはなくなる。
【００１３】
貯湯容器２が満水状態の場合は加熱時間が長くなるので温度検出手段６の追従性はよくなるので温度検出手段６より得られる温度情報で沸騰状態と判断してヒーター４の加熱を停止するので器体外に蒸気が出ることはない。もし、蒸気温度検出手段８で蒸気を検出するまで加熱し続けると貯湯容器２からお湯が噴きこぼれてしまう。
【００１４】
以上のように雰囲気温度や貯湯容器２内のお湯の初期温度、量等で温度検出手段６の追従性が悪くても、温度検出手段６、蒸気温度検出手段８のはやく沸騰検知した方で沸騰状態と判断することにより器体外に蒸気が出ることはなくなる。
【００１５】
（実施例１）
以下、本発明の第一の実施例について説明する。図２は本発明の実施例１の構成を示すブロック図である。浄水器付き電気湯沸かし器の構成要素において、図１と同番号は参考例と同様のものである。２０は貯湯容器２内の水位を検出するための水位検出手段である。２１は貯湯容器２内に浄水を給水する場合に貯湯容器２内のお湯の温度が極度に低下しないように制御するための一定温度制御手段である。
【００１６】
以下本実施例の動作について説明する。一定温度制御手段２１は貯湯容器２内のお湯の温度が一定になるようにヒーター４の加熱をオンしたりオフしたりしている。ここでは９５℃で温度調整をしているとする。次に給水は貯湯容器２の水位を水位検出手段２０で検出して満水状態でなく。かつ、お湯の温度が９５℃以上の時、一定量の浄水を貯湯容器２内に給水できるようにする。この時の給水量は貯湯容器２が１Ｌから２Ｌでは１００ｍＬぐらいが適当である。以上より貯湯容器２内のお湯の温度が高いときに給水するので温度が極度に低下しないように給水することができる。
【００１７】
（実施例２）
以下、本発明の第二の実施例について説明する。図３は本発明の実施例２の構成を示すブロック図である。浄水器付き電気湯沸かし器の構成要素において、図１と同番号は第一の実施例と同様のものである。３０はヒーター４の加熱オフ時間を計る計時手段である。
【００１８】
以下本実施例の動作について説明する。一定温度制御手段２１は貯湯容器２内のお湯の温度が一定になるようにヒーター４の加熱をオンしたりオフしたりしている。ここでは９５℃で温度調整をしているとする。次に給水は貯湯容器２の水位を水位検出手段２０で検出して満水状態でなく。かつ、お湯の温度が９５℃以上の時、一定量の浄水を貯湯容器２内に給水できるようにする。この時、お湯の温度に関係なくヒーター４の加熱をオフにする。そして計時手段３０で時間を計り決められた時間が過ぎると一定温度制御手段２１がヒーター４の加熱をオンにする。この時の加熱オフ時間は貯湯容器２が１Ｌから２Ｌで給水量が１００ｍＬの場合１０秒ぐらいが適当である。もし、この加熱オフ時間がなければ貯湯容器２内のお湯が多い場合で一定量給水した後でもお湯の温度が９５℃未満にならないとき、再び一定量給水してしまいお湯の温度が極度に低下する。
【００１９】
以上より加熱オフ時間があるので給水されると９５℃未満になり確実にヒーターの加熱オン期間が入るのでお湯の温度が極度に低下することが防止できる。
【００２０】
（実施例３）
以下、本発明の第三の実施例について説明する。図４は本発明の実施例３の構成を示すブロック図である。浄水器付き電気湯沸かし器の構成要素において、図１と同番号は第一の実施例と同様のものである。４０は水道水圧が高い場所でも浄水器１から得た浄水を浄水吐出口１１側、または、貯湯容器２側へ流れるように切り換えるように給水弁１３と切り換え弁３の切り換えタイミングを制御するための給水制御手段である。
【００２１】
以下本実施例の給水制御手段の切り換え弁３を浄水吐出口１１側から貯湯容器２側へ切り換える動作を説明する。まず、給水弁１３をオフにして水道蛇口１０から水圧がかからないようにする。そして、水道蛇口１０から水圧がかかっている間は切り換え弁３は切り換えをしない。給水弁１３をオフにして数百ミリ秒すると切り換え弁３にかかる水圧が低下するので、この時に切り換え弁３を貯湯容器２側へ切り換え、給水弁をオンにして給水する。
【００２２】
もし、給水弁１３をオフした後すぐに切り換え弁３を切り換えようとするが水圧のため切り換わらない。この場合、浄水は浄水吐出口１１側に吐出され貯湯容器２に給水されないためお湯の温度が上がりやすくなる。以上より給水制御手段４０で切り換え弁３を確実に切り換わるように給水弁１３をオフにして数百ミリ秒待って貯湯容器２側に切り換えて給水することによりお湯の温度が極度に上昇しないようにしている。
【００２３】
【発明の効果】
本発明の請求項１〜２によれば、給水で極端に貯湯容器内の湯の温度が低下しないようにすることができ、また、給水した後で、さらに給水されて湯温が限度を超えて低下するのを防止することができ、したがって、給湯温度の安定した浄水器付き電気湯沸かし器を実現するものである。

[0008]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0009]
( Reference Example 1)
FIG. 1 is a block diagram showing a configuration of a reference example of the present invention. A water supply valve 13 supplies or stops water from the water tap 10. Reference numeral 1 denotes a water purifier made of activated carbon or a hollow fiber filter. One is connected to the water supply valve 13 and the other is connected to the switching valve 3. A hot water storage container 2 heats water in the hot water storage container by a heater 4. 3 is a switching valve for switching the flow of purified water from the water purifier 1 to the purified water discharge port 11 side and the hot water storage container 2 side. Reference numeral 5 denotes an electric pump for discharging hot water in the hot water storage container 2 to the outlet 12. Reference numeral 6 denotes a temperature detection means for detecting the temperature of hot water in the hot water storage container 2. Reference numeral 14 denotes a hot water drainage path for discharging hot water in the hot water storage container 2, which is adjusted by opening and closing the hot water drainage valve 15. Reference numeral 7 denotes a steam discharge path for discharging the steam generated in the hot water storage container 2 to the outside of the container. Reference numeral 8 denotes steam temperature detecting means for detecting the steam temperature passing through the steam discharge path 7.
[0010]
The operation of this reference example will be described below. First, when the purified water is to be used, the switching valve 3 is switched so that the purified water obtained from the water purifier 1 flows to the purified water discharge port 11 side by pushing a water purification switch (not shown). Then, by opening the water supply valve 14, the raw water from the water tap 10 is purified through the water purifier 1 in this water channel and discharged from the purified water discharge port 11.
[0011]
Next, when using purified hot water, in order to supply water to the hot water storage container 2, the switching valve 3 is switched so that the purified water obtained from the water purifier 1 flows to the hot water storage container 2 side, and the water supply valve is opened. The purified water stored in the hot water storage container 2 is heated by the heater 4. When a hot water switch (not shown) is pressed, the electric pump 5 is driven only while the hot water switch is pressed, and the hot water in the hot water storage container 2 is discharged from the hot water outlet 12.
[0012]
Next, boiling detection using the temperature detection means 6 and the steam temperature detection means 8 will be described. When heated by the heater 4, the water in the hot water storage container 2 is heated and the temperature rises. At this time, the temperature information obtained by the temperature detection means 6 and the actual temperature of the hot water are low in the temperature information that can be obtained when the temperature detection means 6 is poor in the case of a small amount of hot water. Therefore, even if the hot water reaches 100 ° C., the hot water continues to be heated until the temperature information obtained from the temperature detecting means 6 reaches 100 ° C. Thereby, a lot of steam goes out of the container. In the present invention, even in the case of such a small amount of hot water, the steam temperature detecting means 8 is provided in the steam discharge path 7 and the heating of the heater 4 is stopped by determining the boiling state by detecting the steam. Steam will not come out.
[0013]
When the hot water storage container 2 is full, the heating time becomes longer, so that the followability of the temperature detecting means 6 is improved. Therefore, the heating information of the heater 4 is stopped based on the temperature information obtained from the temperature detecting means 6. There is no vapor coming out of the body. If the heating is continued until the steam is detected by the steam temperature detecting means 8, hot water spills from the hot water storage container 2.
[0014]
As described above, even if the temperature detection means 6 has poor followability due to the atmospheric temperature or the initial temperature and amount of hot water in the hot water storage container 2, the temperature detection means 6 and the steam temperature detection means 8 will boil when the boiling is detected quickly. By judging the state, steam does not go out of the container.
[0015]
(Example 1)
The first embodiment of the present invention will be described below. FIG. 2 is a block diagram showing the configuration of the first embodiment of the present invention. In the components of the electric water heater with a water purifier, the same numbers as those in FIG. 1 are the same as those in the reference example. Reference numeral 20 denotes a water level detection means for detecting the water level in the hot water storage container 2. Reference numeral 21 denotes a constant temperature control means for controlling so that the temperature of hot water in the hot water storage container 2 does not extremely decrease when purified water is supplied into the hot water storage container 2.
[0016]
The operation of this embodiment will be described below. The constant temperature control means 21 turns on or off the heating of the heater 4 so that the temperature of the hot water in the hot water storage container 2 becomes constant. Here, it is assumed that the temperature is adjusted at 95 ° C. Next, the water supply is not full when the water level in the hot water storage container 2 is detected by the water level detection means 20. In addition, when the temperature of the hot water is 95 ° C. or higher, a certain amount of purified water can be supplied into the hot water storage container 2. The amount of water supplied at this time is suitably about 100 mL when the hot water storage container 2 is 1 L to 2 L. As described above, since the water is supplied when the temperature of the hot water in the hot water storage container 2 is high, the water can be supplied so that the temperature does not extremely decrease.
[0017]
(Example 2)
The second embodiment of the present invention will be described below. FIG. 3 is a block diagram showing the configuration of the second embodiment of the present invention. In the components of the electric water heater with a water purifier, the same numbers as those in FIG. 1 are the same as those in the first embodiment. Reference numeral 30 denotes a time measuring means for measuring the heating off time of the heater 4.
[0018]
The operation of this embodiment will be described below. The constant temperature control means 21 turns on or off the heating of the heater 4 so that the temperature of the hot water in the hot water storage container 2 becomes constant. Here, it is assumed that the temperature is adjusted at 95 ° C. Next, the water supply is not full when the water level in the hot water storage container 2 is detected by the water level detection means 20. In addition, when the temperature of the hot water is 95 ° C. or higher, a certain amount of purified water can be supplied into the hot water storage container 2. At this time, the heating of the heater 4 is turned off regardless of the temperature of the hot water. When the time determined by the time measuring means 30 has passed, the constant temperature control means 21 turns on the heating of the heater 4. The heating off time at this time is suitably about 10 seconds when the hot water storage container 2 is 1 L to 2 L and the water supply amount is 100 mL. If there is a lot of hot water in the hot water storage container 2 without this heating off time, if the hot water temperature does not drop below 95 ° C even after a certain amount of water is supplied, a certain amount of water is supplied again and the temperature of the hot water drops extremely. To do.
[0019]
As described above, since there is a heating-off time, when the water is supplied, the temperature becomes less than 95 ° C., and the heating-on period of the heater is surely entered.
[0020]
(Example 3)
The third embodiment of the present invention will be described below. FIG. 4 is a block diagram showing the configuration of Embodiment 3 of the present invention. In the components of the electric water heater with a water purifier, the same numbers as those in FIG. 1 are the same as those in the first embodiment. 40 is for controlling the switching timing of the water supply valve 13 and the switching valve 3 so that the purified water obtained from the water purifier 1 flows to the purified water discharge port 11 side or the hot water storage container 2 side even in a place where the tap water pressure is high. It is a water supply control means.
[0021]
Hereinafter, an operation of switching the switching valve 3 of the water supply control means of this embodiment from the purified water discharge port 11 side to the hot water storage container 2 side will be described. First, the water supply valve 13 is turned off so that water pressure is not applied from the water tap 10. The switching valve 3 does not switch while water pressure is applied from the water tap 10. When the water supply valve 13 is turned off for several hundred milliseconds, the water pressure applied to the switching valve 3 decreases. At this time, the switching valve 3 is switched to the hot water storage container 2 side, and the water supply valve is turned on to supply water.
[0022]
If the switching valve 3 is switched immediately after the water supply valve 13 is turned off, the switching is not performed due to water pressure. In this case, since the purified water is discharged to the purified water discharge port 11 side and not supplied to the hot water storage container 2, the temperature of the hot water is easily increased. As described above, the water supply control means 40 turns off the water supply valve 13 so that the switching valve 3 can be switched reliably, waits for several hundred milliseconds, and switches to the hot water storage container 2 side to supply water so that the temperature of hot water does not rise excessively. I have to.
[0023]
【The invention's effect】
According to the first and second aspects of the present invention, it is possible to prevent the temperature of the hot water in the hot water storage container from drastically decreasing due to the water supply, and after the water is supplied, the water is further supplied and the hot water temperature exceeds the limit. Therefore, an electric water heater with a water purifier with a stable hot water supply temperature is realized.
