経過と共に高くなる。In the refrigeration cycle, the refrigerant discharged from the compressor 1 passes through the refrigerant passage of the water heater 2, then sequentially passes through the pressure reducer 3 and the heat absorber 4, and is sucked into the compressor 1 again. is forming. On the other hand, in the water circuit, water pumped up from the tank 7 by the pump 6 is supplied to the water heater 2.
After passing through the water circuit, it returns to tank 7 again. In the water heater 2, heat is transferred from the high temperature refrigerant passing through the refrigerant passage in the water heater 2 to the water passing through the water passage in the water heater 2. The temperature of the water inside increases over time.

てしまう。However, when the high temperature water stored in the tank 7 is not used, the heat in the tank Y moves upward due to natural convection and escapes from the piping between the tank 7 and the drain valve 9.
そこで本発明は従来のヒートポンプ給湯機にみられた以
上のような欠点を解消し、自然対流によるタンク中の熱
の逃散を防止するものである。Therefore, the present invention eliminates the above-mentioned drawbacks of conventional heat pump water heaters and prevents heat from escaping in the tank due to natural convection.

Further, the water tank 16 is connected to a water supply source via a water supply pulp 18, and is connected to a drainage source via a drain valve 19.
次に本発明のヒートポンプ給湯機の制御装置の一太施汐
りについて第３図を参照して説明を行う。Next, the operation of the control device for the heat pump water heater according to the present invention will be explained with reference to FIG. 3.
同図において、２０は電源であり、スイッチ２１を介し
て前記電磁開閉弁１４、前記圧縮機１ｏおよび前記ポン
プ１７が心気配線により各々並列に接続されている。In the figure, 20 is a power source, and the electromagnetic on-off valve 14, the compressor 1o, and the pump 17 are connected in parallel through a switch 21 by an air-chondrium wiring.
以上の構成において次に動作について第２図および第３
図を参照して説明を行う。Next, regarding the operation of the above configuration, see Figures 2 and 3.
The explanation will be given with reference to the figures.

が行われるために、タンク１６中の水の温度は時間の経
過と共に高くなる。When switch 21 is closed, compressor 10 and pump 17
is energized and operates, and the electromagnetic on-off valve 14 opens. For this reason, in the refrigeration cycle, the refrigerant discharged from the compressor 10 passes through the refrigerant passage of the water heater 11 and then passes through the pressure reducer 1
2. A refrigeration cycle is formed in which the water passes through the heat absorber 13 and is sucked into the compressor 10 again. On the other hand, in the water circuit, water pumped up from the tank 16 by the pump 17 passes through the water passage of the water heater 11, passes through the electromagnetic on-off valve 14, and returns to the tank 16 again. In the water heater 11 , heat is transferred from the high temperature refrigerant passing through the refrigerant passage of the water heater 11 to the water passing through the water passage of the water heater 11 . The temperature of water increases over time.
タンク１６中に貯えられた湯を利用する場合には、給水
パルプ１８および排水バルブ１９を開けばよく、給水源
からの水圧により排水バルブ１９から湯が排出される。When using the hot water stored in the tank 16, it is sufficient to open the water supply pulp 18 and the drain valve 19, and the hot water is discharged from the drain valve 19 by water pressure from the water supply source.
タンク１６中の湯が十分に高温となり、スイッチ２１を
開くと圧縮機１０およびポツプ１７への通電は正寸り、
電磁開閉弁１４は閉じることになる。When the hot water in the tank 16 reaches a sufficiently high temperature and the switch 21 is opened, the compressor 10 and the pop-up 17 are energized correctly.
The electromagnetic on-off valve 14 will be closed.
タンク１６中に湯を保温中には、断熱材１５のためにタ

よりタンク１６中の熱が上方向に移動しタンク１６と排
水バルブ１９との間の配管から逃散することはない。While the hot water is being kept warm in the tank 16, the heat insulating material 15 prevents heat from escaping from the tank 16 to the outside by heat conduction, and since the electromagnetic on-off valve 14 is closed, the water in the tank 16 is kept warm by natural convection. Heat does not move upward and escape from the piping between tank 16 and drain valve 19.

閉とする市り御装置を設けたものである。As is clear from the second explanation, the heat pot water heater of the present invention comprises a refrigeration cycle consisting of a compressor, a refrigerant passage of a water heater, a pressure reducer, and a heat absorber, a water passage of a water heater, and an electromagnetic cycle. It consists of a shut-off valve, a tank, and a pump that are connected in a circular manner through water piping, and when the compressor and the pump 11 are energized, the electromagnetic shut-off valve is opened, and the compressor and the pump are de-energized. A control device for closing the electromagnetic on-off valve is provided inside.
