あつた。 In a pump pressure water supply system, a hot water pump and an air-filled accumulator are installed in sequence in the middle of a hot water pipe that connects a hot water storage tank and a hot water tap, and the hot water in the hot water storage tank is supplied by the hot water pump. In addition to supplying pressure to the tap side, the hot water supply pump is controlled to start and stop via a pressure switch that detects the air pressure inside the accumulator, but during long-term use, the air inside the accumulator is gradually discharged to the outside along with the hot water. , the amount of air in the accumulator decreases, resulting in problems such as pump noise or failure due to frequent starting and stopping of the pump.

(See No. 196376). However, in the case of this prior application,
Air is supplied to the accumulator through the ventilate effect via the capillary tube connected to the upstream side of the pump in the hot water supply pipe, so
Air is continuously supplied during pump operation, and there is a risk that the pump blades may be destroyed due to cavitation caused by excessive air supply.

ここで水熱交換器７によつて加熱される。 This pump-feeding hot water supply apparatus has a hot water storage tank 1 in which a water heat exchanger 7 is disposed at the bottom thereof.
Refrigerant pipes 5 and 6 are connected to this water heat exchanger 7, and the hot gas sent from the refrigerator (not shown) is condensed into a liquid refrigerant in the water heat exchanger 7. The condensation heat generated in the hot water storage tank 1
It is designed to heat the water inside. Further, the cold water sent from the water supply pipe 2 side via the ball tap valve 3 is sent to the bottom of the hot water storage tank 1 through an internal water supply pipe 4 provided along the side wall of the hot water storage tank 1.
Here, it is heated by a water heat exchanger 7.

制御される。 The upper part of the hot water storage tank 1 and the hot water tap 19 are connected by a hot water pipe 9. This hot water pipe 9 includes a hot water pump 15, a check valve 20, an accumulator 16,
and a flow switch 18 are provided in this order.
Air is sealed in the accumulator 16, and a pressure switch 17 is provided which operates in response to changes in the pressure of the sealed air (that is, closes when the pressure decreases). The hot water supply pump 15 is controlled to start and stop by the pressure switch 17 and flow switch 18.

と共に吸入される。 Further, the hot water storage tank 1 has one end 25a open to the atmosphere inside the hot water storage tank 1, and the other end 25a.
5b is an air chamber 25 opened at the inlet of the hot water pipe 9
is attached. The air chamber 25 is connected to the discharge side of the hot water pump 15 via a bypass line 26. That is, when the hot water supply pump 15 is operated, a portion w of the hot water discharged from the hot water supply pump 15 flows into the air chamber 25 through the bypass pipe 26. Therefore, the air in the air chamber 25 is pushed out by the inflow and discharged hot water w, and is sucked into the hot water supply pipe 9 together with the hot water.

Any hot water passage between the vicinity of the inlet and the hot water supply pump 15 may be used. For example, a structure as shown in FIG. 2 may be used. In this case, the air forms bubbles A and is sucked into the hot water supply pipe 9. Also, the bypass pipe line 26
has a smaller diameter than the hot water supply pipe 9.
次に図示のポンプ圧送式給湯装置の作用を説明
する。 Next, the operation of the illustrated pump-feeding water heater will be explained.

ンプ１５の運転初期におけるものであることを考
慮すれば、上記エア補給量で十分なのである。 When the hot water tap 19 is opened, the accumulator 16
The pressure of the enclosed air decreases, and in response, the pressure switch 17 closes and the hot water pump 15 operates. Then, a portion w of the hot water discharged from the hot water supply pump 15 flows into the air chamber 25 through the bypass pipe 26, and pushes out the air in the air chamber 25 from the other end 25b. The air pushed out in this way is sucked into the hot water supply pipe 9, mixes into the hot water, and is pumped into the hot water pump 15.
It flows down to the accumulator 16 side, separates from hot water in the accumulator 16, and is stored in the air reservoir 16a at the upper part of the accumulator 16. After the air chamber 25 is filled with the inflow hot water w from the bypass pipe line 26, the supply of air is stopped, and the inflow hot water w is returned to the hot water storage tank 1 from one end 25a of the air chamber 25. . Therefore, air is supplied to the accumulator 16 in an amount corresponding to the capacity of the air chamber 25 at the beginning of operation of the hot water supply pump 15. Considering that most of the amount of air carried away with hot water from the accumulator 16 is during the initial operation of the hot water supply pump 15, the above amount of air replenishment is sufficient.

ることができるのである。 Further, when the hot water tap 19 is closed, the pressure of the air sealed in the accumulator 16 increases, and accordingly, the pressure switch 17 is opened and the hot water pump 15 is stopped. Then, from the bypass pipe 26 to the air chamber 2
The flow of a portion of the hot water into the air chamber 25 stops, and at the same time, air flows from one end 25a of the air chamber 25 into the air chamber 25.
The air flows into the tank and is stored there, allowing the necessary amount of air to be supplied the next time the hot water pump 15 is restarted.

12 is a drain pipe, 12 is a return pipe for hot water to prevent freezing of the internal piping, and 21 is a solenoid valve.
続いて、本発明のポンプ圧送式給湯装置の効果

みならず過剰なエア補給による給湯ポンプ１５へ
の悪影響も防止できるという優れた効果がある。 According to the present invention, the hot water supply pump connects the air chamber 25, which has one end 25a open to the atmosphere in the hot water storage tank 1 and the other end 25b opened to the hot water passage from near the entrance of the hot water pipe 9 to the hot water pump 15. 15, and at the beginning of operation of the hot water pump 15,
Since the air in the air chamber 25 is pushed out by a portion w of the discharged hot water and sucked into the hot water supply pipe 9,
The amount of air supplied to the accumulator 16 can be limited to only the necessary amount, which has the excellent effect of not only smoothing the hot water supply operation but also preventing adverse effects on the hot water supply pump 15 due to excessive air supply.
又、エア室２５を給湯ポンプ１５の吐出側に接
続しているだけなので、可動部分が全くなく、電
磁弁等でエア補給量を制御するものに比べて信頼
性において著しく優れている。 Furthermore, since the air chamber 25 is simply connected to the discharge side of the hot water supply pump 15, there are no moving parts at all, and the reliability is significantly superior to that in which the amount of air replenishment is controlled using a solenoid valve or the like.
