Description
Technical field
The present invention relates to a kind of have for blast pipe and by combustion blower through carry out the hot water supply device of the discharge of the supply of combustion air and burning and gas-exhausting for blast pipe.
Background technology
As this hot water supply device, the applicant crosses as shown in Figure 3 hot water supply device in first to file, and is disclosed in and specially is willing on 2003-113734 number (application number in China is 03123727.4) communique.Should have: housing 1 at the hot water supply device of first to file, be configured in the housing 1 and receive burner 2 is housed and by burner 2 and heated heat supply water with the combustion chamber 4 of heat exchanger 3, be positioned at the top position of combustion chamber 4 and be configured in housing 1 and be communicated in the air supply chamber 5 of the inner space of housing 1, by be communicated in combustion chamber 4 and form the interior pipe 6a of exhaust line 7 and be communicated in air supply chamber 5 and and interior pipe 6a between form dual pipe structure that the outer tube 6b on air feed road 8 constitutes for blast pipe 6, with outer gas through the air feed road 8 with the inner space of air supply chamber 5 and housing 1 as combustion air be supplied in combustion chamber 4 simultaneously with the burning and gas-exhausting of burner 2 from the combustion chamber 4 combustion blowers 9 of discharging through exhaust line 7 in the outside.
In addition, if use aforesaid dual pipe structure for blast pipe 6, the burning and gas-exhausting of the high temperature of the exhaust line of flowing through 7 will be flowed through about air heat to 70～100 ℃ on air feed road 8 sometimes.Place like this and pay no attention to, then have high temperature air in the housing 1 and flow into, the control module 10 that is provided with in combustion blower 9 and the housing 1 can present intensification, thereby may cause that its action is bad or produce the problem of misoperation.
Therefore, in first to file, in air supply chamber 5, having disposed is situated between is located at from heat supply water with water supply road 11 branches of the upstream side of burner 3 and collaborate in heat supply water with cooling on the bypass that goes out hot water road 12 13 in the downstream of heat exchanger 3 with heat exchanger 14, utilize flow through in the cold water of bypass 13 with cool off the high temperature air that will flow in the air supply chamber 5 and carry out heat exchange, cooling with heat exchanger 14.
In addition, when being when not possessing cooling with the hot water supply device of heat exchanger, as everyone knows, in the past, make bypass and the interflow portion that goes out the hot water road be positioned at the top position of the vertical direction for the branching portion on bypass and water supply road, be mingled with phenomenon (for example, with reference to No. 2678330 communique of special permission) to prevent cold water.Cold water is mingled with phenomenon and is meant when going out hot water and stop, branching portion from bypass and cold water road, through heat supply water heat exchanger. bypass and the interflow portion that goes out the hot water road. bypass via the road, return warm water and cold water in the closed circuit of branching portion, in closed circuit, flow to rotation because of both difference in specific gravity, cold water in the bypass stream, return heat supply water heat exchanger side from interflow portion adverse current, so that have cold water to be detained at heat supply water with the part that goes out the hot water road between heat exchanger and interflow portion, the phenomenon that when going out hot water again, has this cold water to flow out.
This is further described.At first, above-mentioned closed circuit being divided into the 1st and the 2 two stream of oppositely linking its vertical direction extreme higher position and vertical direction extreme lower position mutually considers.And, with in the 1st stream and the proportion of occluded water at the arbitrary height y place in the 2nd stream be defined as ρ 1, ρ 2 respectively, the integrated value from the extreme lower position of the 1st stream and the 2nd stream to the vertical direction of the proportion of the occluded water of extreme higher position is defined as ∫ ρ 1dy, ∫ ρ 2dy respectively.Acceleration of gravity be multiply by vertical direction integrated value ∫ ρ 1dy, the ∫ ρ 2dy of occluded water of each stream and the value that obtains, equal the hydraulic pressure of each stream of its lowest position of closed circuit.Thus, so that ∫ ρ 1dy=∫ ρ 2dy flows occluded water.
Bypass and the interflow portion that goes out the hot water road generally are to be positioned at the position that is the vertical direction equal height with the branching portion on bypass and water supply road.In this case, if make the 1st stream be: from as the heat supply water of the vertical direction extreme higher position of closed circuit export department with heat exchanger, through interflow portion and bypass and to stream as the branch branch road of the vertical direction extreme lower position of closed circuit, make the 2nd stream be: from the export department of heat supply water with heat exchanger, arrive the stream that divides branch road with heat exchanger through heat supply water, then because the influence of the cold water that is detained with the part (part of the 2nd stream) on the water supply road between the inlet portion of heat exchanger at branching portion and the heat supply water above it just has ∫ ρ 1dy＜∫ ρ 2dy.Thus, the occluded water in the 2nd stream flow to the 1st stream side through branching portion, and the cold water in the bypass flow to heat supply water heat exchanger side from interflow portion, is mingled with phenomenon thereby cold water takes place.
To this, if make bypass and the interflow portion that goes out the hot water road be positioned at the top position of the vertical direction for the branching portion on bypass and water supply road, then because of the influence of the cold water that in bypass, is detained, the proportion integrated value ∫ ρ 1dy of the occluded water of the 1st stream increases, suppressed from the 2nd stream via towards the flowing of the occluded water of the branching portion of the 1st stream, also promptly suppressed the generation that cold water is mingled with phenomenon.
Yet, when being when having above-mentioned cooling in first to file with the hot water supply device of heat exchanger 14, as above-mentioned shown in Figure 3, if make bypass 13 and the 13b of interflow portion that goes out hot water road 12 be positioned at the top position of the vertical direction for the branching portion 13a on bypass 13 and water supply road 11, then when going out hot water and stop, utilize heat supply water to be transferred to cooling heat exchanger 14 at the hot water of the high temperature that seethed with excitement afterwards with heat exchanger 3, when going out hot water again, will produce the problem that the hot water temperature is high temperatureization.
Fig. 4 is the each point that is illustrated in A～D of Fig. 3, that is, near the B point the 13b of interflow portion of the A point in the interflow portion 13b downstream that goes out hot water road 12, bypass 13, cooling water temperature with near the D point institute instrumentation the branching portion 13a of the C point of the centre of heat exchanger 14 and bypass 13.T1 is the moment when stopping hot water, the moment of t2 when beginning hot water again, from go out hot water stop to the time that begins again be 1 minute.In addition, when going out hot water, the water temperature of controlling out the interflow portion 13b downstream on hot water road 12 reaches 40 ℃, and, after going out hot water and stopping, utilizing the continuation action of combustion blower 9 to carry out the back removing (purge) in 5 seconds.As shown in Figure 4, in the moment that stops hot water, the temperature that B is ordered sharply rises.This is because owing to inertia, and the warm water that goes out hot water road 12 flows into bypass 13 from the 13b of interflow portion.In addition, the actual value of the difference in height between the branching portion 13a of Fig. 3 and the 13b of interflow portion is 2cm.
At this, when going out hot water and stop, from branching portion 13a through heat supply water with the closed circuit that via road return branching portion 13a of heat exchanger 3. 13b. of interflow portion cooling with heat exchanger 14 in, might have occluded water mobile.And, the vertical direction extreme higher position of closed circuit is the highest portion of cooling with heat exchanger 14, the vertical direction extreme lower position of closed circuit is branching portion 13a, in addition, mutually oppositely link the extreme higher position of closed circuit and 2 streams of extreme lower position are: from cooling with the highest of heat exchanger 14 through the 13b of interflow portion and heat supply water with heat exchanger 3 to the 1st stream of branching portion 13a and from cooling with the highest of heat exchanger 14 through cooling with 2nd stream of heat exchanger 14 to branching portion 13a.The proportion integrated value of the vertical direction of the occluded water of the 1st stream, Ying Zaidi 1 stream has heat supply water to exist with heat exchanger and the part of the bypass 13 between 13b of interflow portion and extreme higher position has aforesaid warm water to flow into and diminishes, on the other hand, the proportion integrated value of the vertical direction of the occluded water of the 2nd stream on the 2nd stream almost is a cold water so compare extremely big of seeming with the proportion integrated value of the 1st stream because of being trapped in.Its result produces from the 2nd stream via branching portion 13a towards the flowing of the 1st stream, and heat supply water is with the warm water in the heat exchanger 3, flows into cooling with heat exchanger 14 through the 13b of interflow portion surgingly, and the water temperature that C is ordered sharply rises, and the temperature that D is ordered also rises.
Like this, in a single day cooling has warm water to flow into heat exchanger 14, and the proportion integrated value of the 2nd stream then reduces.Yet, owing to heat supply water rose because of seething with excitement afterwards with the water temperatures in the heat exchanger 3, so the proportion integrated value of the 1st stream also reduces for the proportion integrated value of the 2nd stream.Its as a result heat supply water continue to flow into cooling with heat exchanger 14 with the warm water in the heat exchanger 3 through the 13b of interflow portion, cooling is extremely risen with heat exchanger 14 interior water temperatures.And when going out hot water again, cooling flow to out hot water road 12 with the warm water that the temperature in the thermal converter 14 have risen through the 13b of interflow portion, and it is overheated for the moment to go out the hot water temperature appearance.And be 13.5 ℃ again with respect to the heat of crossing of design temperature (40 ℃).
Summary of the invention
In view of the above-mentioned problems, the present invention with provide a kind of can suppress to go out hot water again the time go out the hot water temperature overheated, have cooling with the hot water supply device of heat exchanger problem as solution.
For solving above-mentioned problem, hot water supply device of the present invention comprises: housing, be configured in the housing and receive burner is housed and by burner and heated heat supply water with the combustion chamber of heat exchanger, be configured in the housing and be positioned at the top position of combustion chamber and be communicated in the air supply chamber of the inner space of housing, by be communicated in the combustion chamber and form the interior pipe of exhaust line and be communicated in air supply chamber and and interior pipe between form the outer tube on air feed road and the dual pipe structure that constitutes for blast pipe, outer gas supplied with the combustion chamber via the inner space of air feed road and air supply chamber and housing as combustion air and the burning and gas-exhausting of burner discharged combustion blower from the combustion chamber via exhaust line in the outside; It is characterized in that: dispose cooling at air supply chamber and use heat exchanger, this cooling is located at from heat supply water with the water supply road branch of the upstream side of heat exchanger and collaborate on the bypass that go out hot water road of heat supply water with the downstream of heat exchanger with heat exchanger Jie; Make bypass and the interflow portion that goes out the hot water road be positioned at lower position with respect to the vertical direction of the branching portion on bypass and water supply road.
According to above-mentioned formation, from the branching portion on bypass pipe and water supply road, through heat supply water heat exchanger. bypass and the interflow portion that goes out the hot water road. bypass via the road, the extreme lower position of vertical direction of returning the closed circuit of branching portion is an interflow portion.And, link the vertical direction extreme higher position of closed circuit and 2 mutual reverse streams of extreme lower position and be: from as the cooling of extreme higher position with the highest portion of heat exchanger via the downstream part of bypass to the 1st stream of interflow portion and from cool off with the highest portion of heat exchanger via cool off upstream portion with heat exchanger, bypass, branching portion, heat supply water with heat exchanger, go out 2nd stream of the upstream portion on hot water road to interflow portion.When going out hot water, because of inertia, the warm water that goes out the hot water road flows into the 1st stream from interflow portion, and the proportion integrated value of the vertical direction of the occluded water of the 1st stream presents minimizing for the moment.On the other hand, though the proportion integrated value of the vertical direction of the occluded water of the 2nd stream has warm water because of heat supply water with heat exchanger, but since in cooling with heat exchanger and the influence of cooling off the cold water that the upstream portion with the bypass between heat exchanger and the branching portion has, will be greater than the proportion integrated value of the 1st stream.Thus, produce from the 2nd stream via interflow portion towards the flowing of the 1st stream, heat supply water flows into to cool off through interflow portion with the warm water in the heat exchanger uses heat exchanger.Yet heat supply water rose because of seething with excitement afterwards with the water temperature in the heat exchanger, and the proportion integrated value of the 2nd stream presents minimizing, finally equals the proportion integrated value of the 1st stream, stops towards the mobile of the 1st stream through interflow portion from the 2nd stream at this moment.Therefore, heat supply water flows into cooling with heat exchanger just for the moment with the warm water in the heat exchanger through interflow portion, has suppressed the rising of cooling with the water temperature in the heat exchanger.Its result goes out the overheated of hot water temperature when also having suppressed to go out hot water again.

The hot water supply device of present embodiment has: housing 1, be configured in the combustion chamber 4 of the roughly seal construction in the housing 1.In combustion chamber 4, receive and burner 2 is housed and passes through burner 2 and heated heat supply water heat exchanger 3.In housing 1, also dispose the top position that is positioned at combustion chamber 4 and be communicated in the air supply chamber 5 of the inner space of housing 1.In addition, be provided with the outer wall W that passes the house and extend to outside the room for blast pipe 6.For blast pipe 6 be by be communicated in combustion chamber 4 and form the interior pipe 6a of exhaust line 7 and be communicated in air supply chamber 5 and and interior pipe 6a between forms the dual pipe that the outer tube 6b on air feed road 8 constitutes and constructs.
In addition, in housing 1, be provided with the combustion blower 9 of the bottom that is communicated in combustion chamber 4.If drive combustion blower 9, outer gas then through the air feed road 8 with the inner space of air supply chamber 5 and housing 1 burned air blast 9 attracts, supply with from this combustion blower 9 as combustion air and to deliver to combustion chamber 4, and simultaneously also by from the blast pressure of combustion blower 9 burning and gas-exhausting of burner 24 forcibly being discharged in the outside through exhaust line 7 from the combustion chamber.In this housing 1, also dispose the control module 10 of control burner 2 and combustion blower 9.
On heat supply water heat exchanger 3, the water supply road 11 that is connected with upstream side and downstream go out hot water road 12.In addition, be provided with and branch out from water supply road 11 and collaborate in the bypass 13 that goes out hot water road 12.And, in air supply chamber 5, dispose cooling with heat exchanger 14, this cooling is with the export department of heat exchanger 14 air supply chamber 5 of interconnecting part between the inner space that becomes air supply chamber 5 and housing 1, and Jie is located on the bypass 13.
On burner 2, be provided with the flame detecting rod 15 and the ignitor 16 of flame detection.In addition, be connected on the fuel gas supply road 17 of burner 2, being situated between successively from the upstream is provided with main solenoid valve 18 and electromagnetic proportional valve 19.On water supply road 11, being situated between is provided with water sensor 20 and DYN dynamic water regulating valve 21.Going out on the hot water road 12, be provided with: be positioned at and the downstream of the 13b of interflow portion of 13 of bypasses and be used to detect hot water temperature's the warm quick resistance 22 of hot water and be positioned at its more safety valve 23 in downstream.
Begin hot water in case open out the tap (not shown) of the downstream on hot water road 12, then receive by water sensor 20 output and corresponding to the signal of streamflow, control module 10 begins to carry out the ignition process of burner 2.According to this ignition process, drive combustion blower 9, supply with combustion chamber 4 with the inner space of housing 1 as combustion air via air supply chamber 5 from the outer gas on air feed road 6.In addition, in the spark discharge of carrying out by ignitor 16, open main solenoid valve 18, but also electromagnetic proportional valve 19 is opened the switching degree of regulation, supply with combustion gas to burner 2, with ignition combustion device 2.And, by the signal that sends by flame detecting rod 15, in case confirmed the igniting of burner 2,10 of control modules carry out according to the adjusting of the quantity combusted of the burner 2 of electromagnetic proportional valve 19 with according to the adjusting of the streamflow of water regulating valve 21, so that the detected temperatures of the warm quick resistance 22 of hot water reaches the hot water temperature of setting.
In addition, the burning and gas-exhausting of burner 2 is flowed through in heat supply water with after the water of heat exchanger 3 having heated, and is discharged from the outside via exhaust line 7.At this moment, by the heat exchange between exhaust line 7 and the air feed road 8, might flow through is heated and is warmed up to about 70～100 ℃ in the outer gas on air feed road 8.Yet, flow into the high temperature air of air supply chamber 5 from air feed road 8, be cooled with the cold water of heat exchanger 14 by the cooling of flowing through in being configured in air supply chamber 5.Therefore, can prevent that air from flowing into the inner space of housing 1 under the state of high temperature, can also prevent to give control module 10 and high temperature that combustion blower 9 brought and then cause the drawback of consequent misoperation etc. by high temperature air.
Though more than with identical in first to file, but in the present embodiment, make bypass 13 and the 13b of interflow portion that goes out hot water road 12 be positioned at the lower position of the vertical direction for the branching portion 13a on bypass 13 and water supply road 11, be different from first to file in this.Below, be elaborated about the action effect that this difference produced.
When going out hot water and stop, from branching portion 13a through heat supply water with the closed circuit that via road return branching portion 13a of heat exchanger 3. 13b. of interflow portion cooling with heat exchanger 14 in, might have occluded water mobile.At this, in the present embodiment, the vertical direction extreme lower position of closed circuit is the 13b of interflow portion.And, link the vertical direction extreme higher position of closed circuit and 2 mutual reverse streams of vertical direction extreme lower position and be: from as the cooling of extreme higher position with the highest portion of heat exchanger 14 via the downstream part of bypass 13 to the 1st stream of the 13b of interflow portion and from cool off with the highest portion of heat exchanger 14 via cool off upstream portion with heat exchanger 14, bypass 13, branching portion 13a, heat supply water with heat exchanger 3, go out 2nd stream of the upstream portion on hot water road 12 to the 13b of interflow portion.In addition, in the present embodiment, the difference in height of setting between branching portion 13a and the 13b of interflow portion is 10cm.
Fig. 2 is the each point that is illustrated in A～D of Fig. 1, that is, near the B point the 13b of interflow portion of the A point in the interflow portion 13b downstream that goes out hot water road 12, bypass 13, cooling water temperature with near the D point institute instrumentation the branching portion 13a of the C point of the centre of heat exchanger 14 and bypass 13.T1 is the moment when stopping hot water, the moment of t2 when beginning hot water again, from go out hot water stop to the time that begins hot water again be 1 minute.In addition, when going out hot water, the water temperature of controlling out the interflow portion 13b downstream on hot water road 12 reaches 40 ℃, and after going out hot water and stopping, and moves the back removing of carrying out for 5 seconds according to the continuation of combustion blower 9.
As shown in Figure 2, in the moment that stops hot water, the temperature that B is ordered sharply rises.This is because because inertia, the warm water that goes out hot water road 12 flow into the cause of bypass 13 from the 13b of interflow portion.In a single day the water temperature of such the 1st stream rises, and then the proportion integrated value of the vertical direction of the occluded water of the 1st stream presents minimizing for the moment.On the other hand, the proportion integrated value of the vertical direction of the occluded water of the 2nd stream, though have warm water because of heat supply water with heat exchanger 3 but have the influence of cold water with the upstream portion of heat exchanger 14 and bypass 13 in cooling, will be greater than the proportion integrated value of the 1st stream.Thus, produce from the 2nd stream via the 13b of interflow portion flowing towards the 1st stream.Its result, heat supply water flows into cooling heat exchanger 14 with the warm water in the heat exchanger 3 via the 13b of interflow portion, and the water temperature that C is ordered rises, and the water temperature that D is ordered also rises.Wherein, the difference of the proportion integrated value of the 2nd stream and the 1st stream is less than the situation in first to file.Thus, from the 2nd stream through the 13b of interflow portion towards the mobile impetus of the 1st stream a little less than, the water temperature that C point, D are ordered is slow rising.
Then, heat supply water rose because of seething with excitement afterwards with the water temperature in the heat exchanger 3, and the proportion integrated value of the 2nd stream presents minimizing, finally equals the proportion integrated value of the 1st stream.And, equal moment (moment of the t3 among Fig. 2) of the proportion integrated value of the 1st stream in the proportion integrated value of the 2nd stream, stop towards the mobile of the 1st stream through the 13b of interflow portion from the 2nd stream.Afterwards, the water temperature that B is ordered descends because of heat release, and the water temperature that D is ordered does not rise yet.In addition, though the water temperature that C is ordered also flow stop the back because of from the combustion chamber 4 heat conduction rise lentamente, if compare with the water temperature that the C of hot water supply device in first to file shown in Figure 4 is ordered, the low of extreme just seems.When going out hot water again, though produce the overheated of hot water temperature, with respect to set hot water temperature's (40 ℃) to cross heat be 10.5 ℃, be that 13.5 ℃ the hot water supply device in first to file is compared and reduced by 3 ℃ with crossing heat.
In addition, on bypass 13, also can considering is situated between is provided with and is used to stop heat supply water to be transferred to the check valve of cooling with heat exchanger 14 with the warm water of heat exchanger 3.But this will raise the cost.To this, in the present embodiment, only be lower than the position of branching portion 13a by the position that makes the 13b of interflow portion, go out the overheated of hot water temperature in the time of just can suppressing to go out hot water again, and be very advantageous in the raising of inhibition cost.
