The specific embodiment
The specific embodiment of the storage type hot water supply device that next, present invention will be described in detail with reference to the accompanying.At first, Fig. 1 is the water loop figure that the major part A of enlarged drawing 5 represents.As shown in the drawing, constitute the bypass 41 that the top with heat storage water tank 2 is connected with the bottom, valve installing port 42 is set and connects discharge valve 43 in this bypass 41.Herein, discharge valve 43 constitutes pressure relief unit, but is interpreted as the part that discharge valve 43 constitutes valve installing port 42.And, at this moment, bypass 41 by the pipe arrangement 36 that is connected with heat exchange department 3,37 and the internal path 3a of heat exchange department 3 constitute.Further describe, bypass 41 is made of the internal path 3a of the top bypass 41a that is connected with the top (top) of heat storage water tank 2, narrow 44, airtrapping portion 45, pipe arrangement 36, heat exchange department 3 and the pipe arrangement 37 that is connected with the bottom (bottom) of heat storage water tank 2.That is, in bypass 41 the high portion that is positioned at the position higher than the top of heat storage water tank 2 is set, this high portion is airtrapping portion 45, and (downside slightly of airtrapping portion) arranges valve installing port 42 in its vicinity.At this moment, at the position configuration valve installing port 42 higher than the top of heat storage water tank 2.In addition, between airtrapping portion 45 and top bypass 41a, form the flow path area narrow 44 littler than the flow path area of other parts of bypass 41.
, further specify above-mentioned airtrapping portion 45 herein, in airtrapping portion 45, when supplying water to casing in the early stage, near atmospheric pressure, but the flowing water dynamic pressure makes the air in the pipe arrangement be present in X portion in the pipe arrangement, and when water supply was finished, the air in the pipe moved to Y portion.At this moment, because the conference of pressure is pressurized to the pressure of discharge valve 43, so volume of air is compressed, but needs to make air trapping in Y portion under this state.Therefore, in conjunction with the ratio of atmospheric pressure with the setting pressure of discharge valve 43, preferably making X portion volume is more than 3 times of Y portion volume.
In above-mentioned bypass 41, arrange above-mentioned narrow 44 and airtrapping portion 45 by-pass shunts and first access 46 that top bypass 41a and bypass 41 (path 36) are communicated with, at this first access 46 first check valve (first flow backwards anti-stop element) 47 is installed.The structure of this first check valve 47 is, do not drive valve under the differential pressure that the convection current that arrives the bottom of heat storage water tanks 2 by top bypass 41a and bypass 41 on the top from heat storage water tank 2 causes, drives valve under the differential pressure that the driving owing to said pump 12 produces.Herein, the caused differential pressure of convection current refer to owing in the heat storage water tank 2 with bypass 41 in the pressure differential that produces of density contrast, because the density contrast of water is 3.6% to the maximum in 0 to 90 ℃ scope, therefore when the height of heat storage water tank 2 is the 2m left and right sides, be the head pressure about 72mm (0.72kPa).
In addition, second access 48 with the front and back by-pass shunt of above-mentioned first check valve 47 is set, installs at this second access 48 and allow air second check valve that flow in 2 top from pressure relief unit 43 to heat storage water tank (second flow backwards anti-stop element) 49.
In the storage type hot water supply device of above-mentioned embodiment, the pressure when turning round as if the boiling of the hot water in heat storage water tank 2 in the heat storage water tank 2 rises, discharge valve 43 work, and then the water at low temperature in the bypass 41 can be distributed to the outside.Like this, what distribute can not be high-temperature-hot-water as in the past, but therefore water at low temperature can suppress loses heat, reduces the accumulation of heat loss.Its result particularly can make device efficiency improve about 3% (proportion is from 15 ℃ of respective amount that drop to 85 ℃).In addition, because air entrapment also distributes to the outside with water at low temperature, therefore exhaust apparatus needn't be set as in the past, can reduce equipment cost.In addition, owing to can suppress distributing of high-temperature-hot-water reliably by narrow 44 is set, therefore can further improve device efficiency reliably.
In addition, since bypass 41 by the pipe arrangement 36 that is connected with heat exchange department 3,37 and the internal path 3a of heat exchange department 3 constitute, bypass 41 is also used as the indispensable structure of storage type hot water supply device, therefore when constituting bypass 41 fully independently relatively, can significantly reduce equipment cost.In addition, with this moment the first required check valve 47 can prevent that high-temperature-hot-water in the heat storage water tank 2 is via bypass 41 free convections.Therefore, also can suppress the produce power loss in this.And, since allow from a side opposite with above-mentioned first check valve 47, namely from the air of pressure relief unit 43 to heat storage water tank 2 side flow, therefore heat storage water tank 2 in during the generation negative pressure (for example from heat supply water downstairs the time) can improve the air inlet performance, prevents the damage of casing 2.
Fig. 2 represents second embodiment.This mode has been omitted second access 48 of first embodiment and the setting of second check valve 49.In this second embodiment, except the item relevant with negative pressure, can obtain the action effect roughly the same with above-mentioned first embodiment.
Fig. 3 represents the 3rd embodiment.This mode is to arrange and the bathroom heating circuit embodiment of other bypass 41 fully independently.In this case, also can obtain water at low temperature is distributed the raising of the energy efficiency of bringing, the such action effect of omission from exhaust apparatus to the outside.
Fig. 4 represents the 4th embodiment.This mode is based on second embodiment, omitted the setting of narrow 44, airtrapping portion 45, and is made of the part of bypass 41 first access 46.In the present embodiment, although need exhaust apparatus 50, except the action effect that narrow 44, airtrapping portion 45 bring, can obtain the action effect roughly the same with second embodiment.In addition, in second to the 4th embodiment, have with the each several part of the first embodiment identical function and use the mark identical with first embodiment to illustrate, omit its explanation.
