図3に示すように、ベース21上には、水を加熱する渦電流加熱装置4と電動モータ51が取り付けられている。渦電流加熱装置4は、ベース21上に立設された平板状のスタンド41に取り付けられている。図4に示すように、渦電流加熱装置4は、回転可能に設けられた回転軸42に固定されたロータ43と、ロータ43の外側に配置された加熱部44で構成される。
As shown in FIG. 3, an eddy current heating device 4 and an electric motor 51 for heating water are mounted on the base 21. The eddy current heating device 4 is attached to a flat stand 41 erected on the base 21. As shown in FIG. 4, the eddy current heating device 4 includes a rotor 43 that is fixed to a rotating shaft 42 that is rotatably provided, and a heating unit 44 that is disposed outside the rotor 43.
回転軸42の右端にはプーリ421が固定され、電動モータ51の出力軸に固定されたプーリ511(図3参照)との間に、ベルト422が掛け渡され、電動モータ51によって回転軸42が回転駆動される。ロータ43は円筒状に形成されており、その外周には多数の永久磁石45が配置されている。ロータ43は継鉄からなるものであり、永久磁石45の内周側の磁路を形成している。ロータ43は中央部が空洞状に形成され、回転軸42に固定されている。回転軸42は、軸受423、424により渦電流加熱装置4に対して回転可能に支持されている。
A pulley 421 is fixed to the right end of the rotating shaft 42, and a belt 422 is stretched between a pulley 511 (see FIG. 3) fixed to the output shaft of the electric motor 51, and the rotating shaft 42 is moved by the electric motor 51. Driven by rotation. The rotor 43 is formed in a cylindrical shape, and a large number of permanent magnets 45 are arranged on the outer periphery thereof. The rotor 43 is made of a yoke, and forms a magnetic path on the inner peripheral side of the permanent magnet 45. The central portion of the rotor 43 is formed in a hollow shape, and is fixed to the rotating shaft 42. The rotating shaft 42 is rotatably supported with respect to the eddy current heating device 4 by bearings 423 and 424.
加熱部44は永久磁石45の外周と微少な間隙を有して配置され、永久磁石45の外周全周を取り巻くドーナツ状に形成されている。加熱部44の内部は中空状に形成されており、その空間が加熱用の水を流通させるための流通路44Bとして機能する。加熱部44の内部には、内周壁44Aに螺旋状の仕切壁44Cが形成されている。この仕切壁44Cにより、流通路44Bは加熱部44の内部に螺旋状に形成されている。
The heating unit 44 is arranged with a slight gap from the outer periphery of the permanent magnet 45 and is formed in a donut shape surrounding the entire outer periphery of the permanent magnet 45. The inside of the heating unit 44 is formed in a hollow shape, and the space functions as a flow passage 44B for circulating water for heating. Inside the heating unit 44, a spiral partition wall 44C is formed on the inner peripheral wall 44A. Due to the partition wall 44 </ b> C, the flow passage 44 </ b> B is spirally formed inside the heating unit 44.
加熱部44の内周壁44Aは、ステンレス綱、アルミニウム合金等の導電材料で形成されている。ロータ43の回転により、外周の永久磁石45による磁力線が内周壁44Aを貫通して移動するため、内周壁44Aに渦電流が発生し、この渦電流による抵抗損失等により内周壁44A自体が発熱する。内周壁44Aで発生した熱は、流通路44Bを通過する水に直接伝達され、また仕切壁44Cを介して水に伝達され、効率的に流通路44B内の水を加熱する。仕切壁44Cは熱伝導率の大きな金属材料で形成されている。
The inner peripheral wall 44A of the heating unit 44 is made of a conductive material such as stainless steel or aluminum alloy. Due to the rotation of the rotor 43, the magnetic lines of force of the outer peripheral permanent magnet 45 move through the inner peripheral wall 44A, so an eddy current is generated in the inner peripheral wall 44A, and the inner peripheral wall 44A itself generates heat due to resistance loss due to this eddy current. . The heat generated in the inner peripheral wall 44A is directly transmitted to the water passing through the flow passage 44B, and is also transmitted to the water through the partition wall 44C to efficiently heat the water in the flow passage 44B. The partition wall 44C is formed of a metal material having a high thermal conductivity.
加熱用の水は、加熱部44に形成された流入口441から加熱部44内に流入し、螺旋状の流通路44Bを通って加熱され、流出口442から渦電流加熱装置4の外に流出する。このように、加熱用の水は螺旋状の流通路44Bを通って、十分な距離を流通する間に加熱されるため、効率よく加熱することができる。
Heating water flows into the heating unit 44 from the inlet 441 formed in the heating unit 44, is heated through the spiral flow path 44 </ b> B, and flows out of the eddy current heating device 4 from the outlet 442. To do. Thus, the heating water is heated while passing through a sufficient distance through the spiral flow passage 44B, so that it can be heated efficiently.
加熱用の水は、図3に示すように、ポンプ52により給水口53から一次フィルタ54を介して吸い上げられ、温度計・流量計55、二次フィルタ56を介して渦電流加熱装置4の流入口441に供給される。渦電流加熱装置4によって十分に加熱された温水は、渦電流加熱装置4の流出口442から、温度計・流量計57、給湯口58を介して後記する浴槽またはシャワーに供給される。温度計・流量計55、温度計・流量計57の温度、流量の検出信号は、側板22に取り付けられた制御盤59に送られ、制御盤59が電動モータ51の回転数を制御する。
As shown in FIG. 3, the water for heating is sucked up by the pump 52 from the water supply port 53 through the primary filter 54, and flows through the eddy current heating device 4 through the thermometer / flow meter 55 and the secondary filter 56. Supplyed to the inlet 441. The hot water sufficiently heated by the eddy current heating device 4 is supplied from the outlet 442 of the eddy current heating device 4 to a bathtub or shower described later via a thermometer / flow meter 57 and a hot water supply port 58. The temperature and flow rate detection signals of the thermometer / flow meter 55 and the thermometer / flow meter 57 are sent to the control panel 59 attached to the side plate 22, and the control panel 59 controls the rotation speed of the electric motor 51.
一次フィルタ54及び二次フィルタ56は、ポンプ52、渦電流加熱装置4に流入する水を濾過し、ゴミや鉄分を除去する。渦電流加熱装置4の加熱部44は、永久磁石45による磁力線が貫通するため、一次フィルタ54及び二次フィルタ56によって鉄分を除去し、流通路44Bに鉄分が付着して水の流通が阻害されないようにしている。
The primary filter 54 and the secondary filter 56 filter the water flowing into the pump 52 and the eddy current heating device 4 to remove dust and iron. The heating unit 44 of the eddy current heating device 4 passes through the magnetic lines of force of the permanent magnet 45, so that the iron content is removed by the primary filter 54 and the secondary filter 56, and the iron content adheres to the flow passage 44B, so that the flow of water is not hindered. I am doing so.

In step S4, the heating temperature (20 ° C. = 41 ° C.−21 ° C.) is calculated from the temperature difference between the set temperature 41 ° C. and the inlet temperature 21 ° C. FIG. 14 is an example of a temperature characteristic graph showing the relationship between the rotor rotation speed (rpm) and the temperature (° C.) of the hot water supply apparatus 1 according to the third embodiment of the present invention. It is a temperature characteristic graph. As shown in FIG. 14, the relationship between the rotor rotation speed (rpm) and the temperature (° C.) of the rotor 43 of the eddy current heating device 4 is linear.

In step S7, the pump 52 is started with the calculated command voltage. If the flow rate detected by the inlet-side thermometer / flow meter 55 and the outlet-side thermometer / flow meter 57 is 2.0 L or more of the minimum flow rate in step S8, the electric motor 51 (see FIG. 3) is determined in step S11. )

The
電動モータ51は三相誘導電動機であり、インバータ制御によって電動モータ51の電圧と周波数を制御して、ロータ43を所定の回転数で回転させる。入口側の温度計・流量計55、出口側の温度計・流量計57で検出した流量が、2秒経過しても最低流量の2.0L未満であれば(ステップS9)、ステップS10でエラー停止し、ポンプ52が停止する。操作盤8の表示装置83には、図示しないエラー画面が表示され、エラーの内容が表示される。
The electric motor 51 is a three-phase induction motor, and controls the voltage and frequency of the electric motor 51 by inverter control to rotate the rotor 43 at a predetermined rotational speed. If the flow rate detected by the inlet-side thermometer / flow meter 55 and the outlet-side thermometer / flow meter 57 is less than 2.0 L of the minimum flow rate even after 2 seconds (step S9), an error occurs in step S10. The pump 52 stops. An error screen (not shown) is displayed on the display device 83 of the operation panel 8, and the content of the error is displayed.
図12に示すように、ステップS12で、出口側の温度計・流量計57で検出したお湯の出口温度が安定したら、ステップS13で、出口側の温度計・流量計57で検出したお湯の出口温度と、図10(b)の温度設定画面で選択した設定温度41℃を取得する。例えば出口温度のサンプリング周期は50msecで行う。ステップS4で算出した加熱温度(20℃=41℃-21℃)の幅に応じて、ステップS12の出口温度が安定したか否か判断するまでの判断時間を異ならせると良い。
As shown in FIG. 12, when the hot water outlet temperature detected by the outlet side thermometer / flow meter 57 is stabilized in step S12, the hot water outlet detected by the outlet side thermometer / flow meter 57 in step S13. The temperature and the set temperature 41 ° C. selected on the temperature setting screen of FIG. For example, the outlet temperature sampling cycle is 50 msec. Depending on the width of the heating temperature (20 ° C. = 41 ° C.−21 ° C.) calculated in step S4, the determination time until it is determined whether or not the outlet temperature in step S12 is stable may be varied.
ステップS14で、出口側の温度計・流量計57で検出したお湯の出口温度が44℃以上であれば、お湯の温度が高く、使用に適さないので、ステップS20でエラー停止し、ポンプ52、電動モータ51が停止する。操作盤8の表示装置83には、図示しないエラー画面が表示され、エラーの内容が表示される。
If the outlet temperature of the hot water detected by the thermometer / flow meter 57 on the outlet side in step S14 is 44 ° C. or higher, the temperature of the hot water is high and not suitable for use. The electric motor 51 stops. An error screen (not shown) is displayed on the display device 83 of the operation panel 8, and the content of the error is displayed.
ステップS15で、出口側の温度計・流量計57で検出したお湯の出口温度と、図10(b)の温度設定画面で選択した設定温度41℃との温度差を算出する。出口側の温度計・流量計57の検出時間の遅れを補正するために、出口温度と設定温度との温度差の算出は、例えば出口温度20回分の平均値で行う。ステップS16では、ステップS15で算出した温度差と図14の温度特性グラフからロータ回転数(rpm)の補正値を算出する。ステップS17で、電動モータ51の回転数を変更し、ステップS16で算出したロータ回転数(rpm)でロータ43を回転させる。
In step S15, a temperature difference between the hot water outlet temperature detected by the thermometer / flow meter 57 on the outlet side and the set temperature of 41 ° C. selected on the temperature setting screen of FIG. 10B is calculated. In order to correct the delay in the detection time of the outlet-side thermometer / flow meter 57, the temperature difference between the outlet temperature and the set temperature is calculated, for example, as an average value for 20 outlet temperatures. In step S16, a correction value for the rotor rotational speed (rpm) is calculated from the temperature difference calculated in step S15 and the temperature characteristic graph of FIG. In step S17, the rotational speed of the electric motor 51 is changed, and the rotor 43 is rotated at the rotor rotational speed (rpm) calculated in step S16.
ステップS18で、出口側の温度計・流量計57で検出したお湯の出口温度が安定したら、ステップ19にすすむ。ステップS18で、出口温度が安定していなければ、安定するまで待機する。ステップS19で、温度補正の周期(本発明の実施の形態では2秒に設定)になったか否か判断し、YESなら、ステップS13に戻る。ステップS19の判定がNOなら、図13に示すように、ステップS21で、最初に設定した設定流量2.0Lが変更されたか否か判断し、変更されていなければ、ステップS19に戻る。設定流量2.0Lが変更されていれば、ステップS22で、変更された設定流量を取得する。
When the hot water outlet temperature detected by the thermometer / flow meter 57 on the outlet side is stabilized in step S18, the process proceeds to step 19. If the outlet temperature is not stable in step S18, it waits until it is stabilized. In step S19, it is determined whether or not the temperature correction period has been reached (set to 2 seconds in the embodiment of the present invention). If YES, the process returns to step S13. If the determination in step S19 is NO, as shown in FIG. 13, it is determined in step S21 whether or not the initially set flow rate 2.0L has been changed. If not, the process returns to step S19. If the set flow rate 2.0L has been changed, the changed set flow rate is acquired in step S22.
ステップS23で、変更された設定流量に対応する温度特性グラフ(図示せず)からロータ回転数(rpm)を算出し、ステップS24で、電動モータ51の回転数を変更して、ステップS23で算出したロータ回転数(rpm)でロータ43を回転させる。ステップS25で、出口側の温度計・流量計57で検出したお湯の出口温度が安定したら、ステップS26にすすむ。ステップS25で、出口温度が安定していなければ、安定するまで待機する。ステップS26で、電動モータ51が過負荷か否か判断し、NOなら、ステップS19に戻る。ステップS26の判定がYESなら、ステップS27でエラー停止し、ポンプ52、電動モータ51が停止する。操作盤8の表示装置83には、図示しないエラー画面が表示され、エラーの内容が表示される。
In step S23, the rotational speed (rpm) of the rotor is calculated from a temperature characteristic graph (not shown) corresponding to the changed set flow rate. In step S24, the rotational speed of the electric motor 51 is changed and calculated in step S23. The rotor 43 is rotated at the rotor rotation speed (rpm). If the hot water outlet temperature detected by the thermometer / flow meter 57 on the outlet side is stabilized in step S25, the process proceeds to step S26. If the outlet temperature is not stable in step S25, it waits until it is stabilized. In step S26, it is determined whether or not the electric motor 51 is overloaded. If NO, the process returns to step S19. If the determination in step S26 is YES, the error is stopped in step S27, and the pump 52 and the electric motor 51 are stopped. An error screen (not shown) is displayed on the display device 83 of the operation panel 8, and the content of the error is displayed.
