Description

本発明は、給湯操作により容器に給湯する給湯装置に関する。   The present invention relates to a hot water supply apparatus that supplies hot water to a container by a hot water supply operation.

水道水を浄化して純水を生成し、その純水を供給する給水装置に、前記純水を加熱してお湯にし、このお湯を供給する機能を有する冷温水給水装置は既に市場に導入されている(例えば、特許文献1参照)。
そして、上記従来の給水装置は給水口(給湯口)の下方に容器を置く場所が配置され、容器を所定の場所に置いて給水ボタンを操作すると、前記容器に純水を給水することができ、又、お湯を必要とする場合も容器を所定の場所に置き、ロック解除ボタンを押した後、給湯ボタンを操作すると、前記容器にお湯が給湯されるものである。
A hot / cold water supply device having a function of supplying pure water to a water supply device that purifies tap water to generate pure water and supplies the pure water to the pure water is already introduced in the market. (For example, refer to Patent Document 1).
In the conventional water supply apparatus, a place where the container is placed is arranged below the water supply port (hot water supply port), and when the container is placed in a predetermined place and the water supply button is operated, pure water can be supplied to the container. Also, when hot water is required, when the container is placed in a predetermined place, the lock release button is pressed, and then the hot water supply button is operated, hot water is supplied to the container.

しかしながら、前記容器を置く場所は給水口(給湯口)の下方に位置して開放されており、容器を所定の場所に置いて給湯ボタンを押すことでお湯が給湯される為、操作者の手が給水口付近にある場合でも、そのままお湯が給湯されていた。
そのため、例えば、容器を所定の場所に置いてそのまま該容器を手で押え、その状態で給湯ボタンを押して給湯した場合、お湯が跳ねて手に掛かるといった危険性がある。又、給湯中に子供が容器付近に手を差し出し、お湯が手に掛かるといった危険性がある。
However, the place where the container is placed is open below the water supply port (hot water supply port), and hot water is supplied by placing the container in a predetermined place and pressing the hot water supply button. Even when there was near the water inlet, hot water was still supplied.
Therefore, for example, when a container is placed in a predetermined place and the container is directly pressed by hand and the hot water supply button is pressed in that state to supply hot water, there is a risk that the hot water jumps and gets on the hand. In addition, there is a risk that the child puts his hand near the container during hot water supply and the hot water gets on his hand.

The door sensor (door open / close determining means 9) is a sensor that detects the closed state of the door 8. For example, when a magnet sensor is used, the energized state (closed state) is determined by the CPU.

次に、本発明に関する給湯装置AのCPUの動作(給湯)の概略を図5のフローチャートに基づいて説明する。尚、このフローチャートは、給湯装置の電源をオンすることでスタートする。
S1…操作部の「ロック解除」ボタン16が押され、容器載部7に哺乳瓶(容器)aが置かれ、「お湯」ボタン(温水用操作ボタン)13が押されたか否かを判断する。押された場合(YES)はS2へ進み、押されていない場合(NO)はS9へ進む。
S2…扉8が閉状態か判断される。具体的には、扉開閉判断手段9(扉センサ)が通電状態か、非通電状態かを判断する。扉が閉状態(通電状態)と判断された場合(YES)はS3に進み、扉が開状態(非通電状態)と判断された場合(NO)はS8へ進む。尚、扉8が完全に開いていなくても、開閉操作レバー10が閉じ位置にないときは非通電状態となるので、扉8は開いていると判断する。
S3…操作部の「お湯」ボタン(温水用操作ボタン)13が押されている間、CPUから温水タンク5の給湯口に接続された電磁弁SV6を開放する開放信号が出力され続け、お湯が温水タンク5から注ぎ口24を介して容器載部7上の哺乳瓶(容器)aに給湯される。
S4…操作部の「お湯」ボタン(温水用操作ボタン)13の押下げが解除されると、電磁弁SV6を閉鎖する閉鎖信号がCPUから出力され、お湯の給湯が停止される。
Next, the outline of the operation (hot water supply) of the CPU of the hot water supply apparatus A according to the present invention will be described based on the flowchart of FIG. This flowchart starts when the power supply of the hot water supply device is turned on.
S1... It is determined whether the “unlock” button 16 of the operation unit is pressed, the baby bottle (container) a is placed on the container mounting unit 7 and the “hot water” button (hot water operation button) 13 is pressed. . If it is pressed (YES), the process proceeds to S2, and if it is not pressed (NO), the process proceeds to S9.
S2: It is determined whether the door 8 is closed. Specifically, it is determined whether the door open / close determining means 9 (door sensor) is energized or not energized. When it is determined that the door is closed (energized state) (YES), the process proceeds to S3, and when the door is determined to be open (non-energized state) (NO), the process proceeds to S8. Even if the door 8 is not completely open, it is determined that the door 8 is open because the open / close operation lever 10 is not energized when it is not in the closed position.
S3: While the “hot water” button (hot water operation button) 13 of the operation unit is being pressed, an open signal for opening the solenoid valve SV6 connected to the hot water supply port of the hot water tank 5 is continuously output from the CPU. Hot water is supplied from the hot water tank 5 to the baby bottle (container) a on the container mounting portion 7 through the spout 24.
S4... When the pressing of the “hot water” button (hot water operation button) 13 of the operation unit is released, a closing signal for closing the solenoid valve SV6 is output from the CPU, and hot water supply is stopped.

S5…給湯後に温水タンク5内の温水の量、或いは、給水後に冷水タンク4内の冷水の量が足りるか判断される。具体的には、タンク底部近傍の水位センサ(28−1或いは29−1)により検知されているか否かを判断する。量が足りず検知されていないと判断された場合(NO)はS6へ進み、量が足りて検知されていると判断された場合(YES)は終了する。尚、水位の検知は、例えばセンサの先端に一対の電極を有し、該電極が通電しているか否かにより判断する。
S6…温水タンク5内の温水の量、或いは冷水タンク4内の冷水の量が足りないと判断された場合には、ポンプP1を駆動し、浄水装置3を透過した水(純水)を、冷水タンク4又は温水タンク5に供給すべく電磁弁SV1或いは電磁弁SV2を開放する。
S7…温水タンク5、或いは冷水タンク4内の略上部の水位センサ(29−3、28−3)にて検知されるまで浄水装置3の浄水動作が続けられる。尚、S5では水位センサ28−1、或いは29−1にて検知されるか否かにより、ポンプP1を駆動させて浄水(純水)を生成するようにしたが、S5で判断するお湯或いは水の量はタンクの略中間の水位を検知するセンサ29−2、28−2のセンサにて検知されるか否かにより判断するようにしてもよい。
S5: It is determined whether the amount of hot water in the hot water tank 5 after hot water supply or the amount of cold water in the cold water tank 4 after supplying water is sufficient. Specifically, it is determined whether the water level sensor (28-1 or 29-1) in the vicinity of the tank bottom is detected. If it is determined that the amount is not detected (NO), the process proceeds to S6, and if it is determined that the amount is detected (YES), the process ends. Note that the detection of the water level is determined by, for example, having a pair of electrodes at the tip of the sensor and whether the electrodes are energized.
S6: When it is determined that the amount of hot water in the hot water tank 5 or the amount of cold water in the cold water tank 4 is insufficient, the pump P1 is driven and water (pure water) that has passed through the water purifier 3 is purified. In order to supply the cold water tank 4 or the hot water tank 5, the electromagnetic valve SV1 or the electromagnetic valve SV2 is opened.
S7: The water purifying operation of the water purifier 3 is continued until it is detected by the water level sensor (29-3, 28-3) in the upper part of the hot water tank 5 or the cold water tank 4. In S5, the pump P1 is driven to generate purified water (pure water) depending on whether it is detected by the water level sensor 28-1 or 29-1, but hot water or water determined in S5. This amount may be determined based on whether or not it is detected by sensors 29-2 and 28-2 that detect a substantially intermediate water level in the tank.

S8…S2で扉8が閉状態ではないと判断されると、フルドット表示部23に「扉を閉じて下さい」のメッセージを表示する。
S9…容器載部7に哺乳瓶(容器)aが置かれ、「冷水」ボタン(冷水用操作ボタン)12が押されたか否かを判断する。押された場合(YES)はS11へ進み、押されていない場合(NO)はS10へ進む。
S10…本発明に直接関係のない増水ボタン14や、再沸騰ボタン15が押された場合で、夫々の処理が実行される。
S11…操作部の「冷水」ボタン(冷水用操作ボタン)12が押されている間、CPUから電磁弁SV4を開放する開放信号が出力され続け、冷水が冷水タンク4から注ぎ口24を介して容器載部7上の哺乳瓶(容器)aに給水される。
S12…操作部の「冷水」ボタン(冷水用操作ボタン)12の押下が解除されると、CPUから電磁弁SV4を閉鎖する閉鎖信号が出力され、冷水の供給が停止される。
When it is determined in S8... S2 that the door 8 is not in the closed state, a message “Please close the door” is displayed on the full dot display portion 23.
S9: It is determined whether the baby bottle (container) a is placed on the container mounting portion 7 and the “cold water” button (cold water operation button) 12 is pressed. If it is pressed (YES), the process proceeds to S11, and if it is not pressed (NO), the process proceeds to S10.
S10: Each process is executed when the water increase button 14 or the reboil button 15 that is not directly related to the present invention is pressed.
S11: While the “cold water” button (cold water operation button) 12 of the operation unit is being pressed, an open signal for opening the electromagnetic valve SV4 is continuously output from the CPU, and cold water is supplied from the cold water tank 4 through the spout 24. Water is supplied to the baby bottle (container) a on the container mounting portion 7.
S12... When the “cold water” button (cold water operation button) 12 on the operation unit is released, the CPU outputs a closing signal for closing the electromagnetic valve SV4, and the supply of cold water is stopped.

このように、給湯の場合には扉が閉じているか否かが判断され、閉じている場合にのみ給湯が開始され、冷水の場合は扉の開閉状態は判断せずに、冷水ボタン12が押されると、直ちに給水動作が開始される。つまり、水の場合は、手や体の一部に水が掛かっても問題ないが、お湯の場合はお湯が掛かると危険であるので必ず扉が閉まっていることを給湯の条件とする。
また、一旦、容器に注がれたお湯がこぼれて、体の一部(例えば手)にお湯が触れて該部分を冷やしたい場合においても、給水を開始する条件に扉の開閉が条件になっていないので、扉を開き、例えば手を注ぎ口24の下に位置させて、冷水ボタン12を押すことで冷水が供給されるので手を冷やすことができる。
また、給湯や給水動作で温水タンクのお湯や冷水タンク内の水が足りなくなったら、自動的に浄水動作が開始されるので、温水タンク内のお湯や、冷水タンク内の水(冷水)が足りなくなることがない。
Thus, in the case of hot water supply, it is determined whether or not the door is closed. Hot water supply is started only when the door is closed. In the case of cold water, the open / close state of the door is not determined and the cold water button 12 is pressed. The water supply operation is started immediately. In other words, in the case of water, there is no problem even if the hand or part of the body is splashed with water. However, in the case of hot water, it is dangerous if the hot water is poured, so that the door must be closed as a condition for hot water supply.
In addition, even when hot water poured into the container is spilled and it is necessary to cool the part by touching it with a part of the body (for example, a hand), opening and closing the door is a condition for starting water supply. Since the cold water is supplied by opening the door and placing the hand under the spout 24 and pressing the cold water button 12, for example, the hand can be cooled.
Also, if there is not enough water in the hot water tank or cold water tank due to hot water supply or water supply operation, the water purification operation will start automatically, so there is not enough hot water in the hot water tank or water in the cold water tank (cold water) It will not disappear.

又、前記S3で電磁弁SV6の開放信号が出力されお湯が給湯されている間、扉開閉判断手段9(扉センサ)の通電状態をCPUが判断し、「お湯」ボタンの押下げの解除とは別に非通電状態と判断した時は、前記電磁弁SV6を閉じる閉鎖信号がCPUから出力され、お湯の給湯を停止させるようにしてもよい。これにより、給湯途中で、何らかの理由により扉が開状態になった時、例えば、子供が扉を開けた場合等、お湯の給湯が停止されるので、誤って手等にお湯が掛かる虞れがなくなる。
尚、「冷水」を給水する場合、扉8の閉状態を「お湯」を給湯する場合と同様、給水の条件としてもよいし、条件にしなくてもよい。扉8の閉状態を給水の条件とした場合は、給水中は扉8が閉じられているため、哺乳瓶(容器)aへの給水にゴミや埃等が入るのを防止できる。
In addition, while the open signal of the solenoid valve SV6 is output in S3 and hot water is being supplied, the CPU determines the energized state of the door open / close determining means 9 (door sensor) and cancels the pressing of the “hot water” button. Alternatively, when it is determined that the state is not energized, a closing signal for closing the solenoid valve SV6 may be output from the CPU to stop the hot water supply. As a result, when the door is opened for some reason during hot water supply, for example, when a child opens the door, the hot water supply is stopped. Disappear.
In the case of supplying “cold water”, the closed state of the door 8 may or may not be a water supply condition as in the case of supplying “hot water”. When the closed state of the door 8 is a water supply condition, the door 8 is closed during water supply, and therefore, dust and dust can be prevented from entering the water supply to the baby bottle (container) a.
