湯槽7上部へ流入する水循環復管である。Conventional Structure and Problems Conventionally, this type of heat pump water heater is shown in FIGS. 1 and 2. In Figure 1, 1 is a compressor, 2
1 is a condenser, 3 is an expansion valve, 4 is an evaporator, 5 is a heat source blower, and 6 is an accumulator, which constitute a refrigerant circuit of the air source heat pump. Also, 7 is a hot water tank, 8
1 is a water circulation outgoing pipe leading from the hot water storage tank 7 to the condenser 2 via the pump 9, 10 is an auxiliary heater disposed downstream of the condenser 2, and 11 is an auxiliary heater 10 located downstream of the condenser 2. This is a return pipe for water circulation that flows into the upper part of the hot water tank 7 through the water tank.

度を一定にして貯湯するものである。12 is a hot water outlet pipe branched from the water circulation return pipe 11;
13 is a water supply pipe. 14 is a temperature detector that detects hot water flowing into the hot water storage tank 7, which changes the rotation speed of the pump and controls the amount of circulating water when the heat pump is operating independently.
When operated in combination with the auxiliary heater, hot water is stored while keeping the temperature of hot water flowing into the hot water storage tank 7 constant.

きないという問題点があった。According to this configuration, when hot water is stored in the hot water storage tank 7, the heat pump and the pump are operated, and the circulating water from the lower part of the hot water storage tank 7 is heated by the condenser 2, and the hot water is made to flow into the top and stored. . When the outside temperature is low, such as in winter, the heating capacity of the condenser 2 decreases, resulting in insufficient capacity to guarantee hot water supply. In such a case, the auxiliary heater 10 is also operated. Furthermore, even in winter, when the outside temperature is low and the humidity is relatively high, frost forms on the evaporator 4, reducing the capacity of the evaporator 4, making it difficult to operate efficiently. In order to prevent this, as shown in FIG. 2, the temperature at the outlet of the evaporator 4 is detected by the temperature detector 15, the solenoid valve 17 in the defrosting circuit 16 is opened, and the heat source blower 5 is stopped. Then, the high-temperature, high-pressure gas refrigerant compressed by the compressor 1 is guided to the evaporator 4 for defrosting. When defrosting is completed, the solenoid valve 17 is closed and the heat source blower 5 is operated for normal operation. During defrosting, most of the refrigerant flows to the evaporator 4 and does not flow to the condenser 2, so only the auxiliary heater 10 is operated during the heating operation, resulting in insufficient heating capacity. In addition, since the rotation speed of the pump 9 is controlled by the temperature sensor 14, in order to obtain a predetermined temperature when the heating capacity decreases, the rotation speed of the pump must be extremely reduced, making control extremely difficult. It was difficult. Particularly in the case of a late-night electric water heater that boils water within a certain period of time, there is a problem in that it is not possible to ensure a specified amount of water up to a specified temperature.
発明の目的
本発明はかかる従来の問題点を解消するもので除霜時に
所定の加熱能力を確保すると共に、制御性の高いヒート
ポンプ給湯装置を提供することを目的とする。OBJECTS OF THE INVENTION The present invention solves these conventional problems, and aims to provide a heat pump hot water supply device that ensures a predetermined heating capacity during defrosting and has high controllability.
発明の構成
この目的を達成するために本発明は、補助加熱器に加熱
入力制御機構を設けると共に、凝縮器の水側温度差を検
知して前記入力制御機構を制御する差温検知器を設けた
ものである。Structure of the Invention To achieve this object, the present invention provides an auxiliary heater with a heating input control mechanism and a temperature difference detector that detects a temperature difference on the water side of the condenser and controls the input control mechanism. It is something that
この構成によって、除霜時、凝縮器に冷媒が流れず凝縮
器が作用しない場合に、凝縮器の水側出入口の温度差を
差温検知器で検知して、補助加熱器の入力制御機構に伝
達し、入力制御機構によシ補助加熱器入力を最大にする
。除霜終了後は凝縮器に冷媒が流れ凝m器の水側出入口
の温度差ができると入力制御機構によって補助加熱器へ
の入力を抑える。With this configuration, during defrosting, when the refrigerant does not flow to the condenser and the condenser does not function, the temperature difference between the water side entrance and exit of the condenser is detected by the temperature difference detector, and the input control mechanism of the auxiliary heater is activated. and maximize the auxiliary heater input through the input control mechanism. After defrosting, refrigerant flows into the condenser, and if a temperature difference occurs between the water side inlet and outlet of the condenser, the input control mechanism suppresses the input to the auxiliary heater.
これによって、除霜時でも所定の給湯温度を確保できる
と共に、除霜時間による沸き上げ時間の遅れをカバーし
、一定時間内に所定の量を所定の温度まで沸き上げるこ
とができ、除霜時のポンプ回転数も極端に低下させるこ
となく制御できるためポンプの制御性も向上する。This makes it possible to maintain a predetermined hot water supply temperature even during defrosting, and to compensate for the delay in boiling time caused by the defrosting time, making it possible to boil a predetermined amount to a predetermined temperature within a certain amount of time. The controllability of the pump is also improved because the pump rotation speed can be controlled without drastically reducing it.

When the temperature falls below the set temperature of 0, the auxiliary first heater 19 is turned on to compensate for the lack of heating capacity in the condenser 2 due to the drop in outside temperature. Furthermore, if the outside air humidity is relatively high and frost forms on the evaporator 4, the temperature at the outlet of the evaporator 4 is detected by the temperature detector 15, the solenoid valve 17 in the defrosting circuit 16 is opened, and the compressor The refrigerant discharge gas from No. 1 is introduced into the evaporator 4 to melt the frost attached to the evaporator 4. Further, the heat source blower 5 is in an off state.
