Abstract

PURPOSE:To reduce the amount of waste water at the start of the discharge of hot water and to shorten a waiting period, by throttling the opening of a hot water passage when the temperature of discharged hot water at the outlet of a heat exchanger is at or lower than a predetermined temperature. CONSTITUTION:A water amount adjusting apparatus 4 having a wax thermostat 6 therein is situated in a hot water outlet of a heat exchanger. Since the wax thermostat 6 is constricted when the temperature of the hot water is still low immediately after the discharge of the hot water, a valve 9 throttles the opening of a passage valve 11. Therefore the amount of the discharged hot water is suppressed to an amount slightly over than a minimum hot water discharge C. When the temperature of the discharge hot water reaches a prescribed temperature, the wax thermostat 6 is extended to widen the passage valve 11 to increase the amount C of the hot water until the passage valve 11 is fully opened. Thus the discharge of the hot water can be stabilized. Therefore, the amount of waste water at the start of the discharge can be reduced and the waiting period can be shortened.

Description

[Detailed description of the invention] [Field of application of the invention] The present invention is a dark type hot water heater (1).

[Prior art] Conventional 0) Luci 1141 water heater No. 11, Fig. 2 (2 + J explanation) 1 is a burner, 2 is a heat exchanger that makes hot water from burner 1c 2 - 3 is a hot water faucet Open the C2 to detect the flow of water θ), and only when there is a flow of ice above a certain level, the burner IQ) gives a signal 7 that indicates the amount of ice is flowing.
It is a flow detector.

There is a heel configuration C2, and the hot water temperature is inversely proportional to the amount of hot water (1), assuming that the combustion heat y from the burner IC2 is constant.On the other hand, the amount of hot water ° is determined by the faucet opening degree C2, and the hot water rises. Characteristics Fig. 2 (explained from 2. When hot water starts to flow, by opening the faucet, hot water A is proportional to the faucet opening (2).C is the minimum flow height at which the water flow detector 3 operates Yes, the combustion starts at to, but the temperature of the hot water coming out of the faucet is a(
As shown in Figure 2, the temperature gradually rises, and after the lapse of time ta, it reaches a level of 1 degree determined by the predetermined amount of hot water and combustion waste heat acid, and becomes stable. 0'Ii3 becomes longer as the amount of hot water increases.

As shown in Figure 1, it takes time Z to reach the specified hot water temperature in the hot water chamber (1), and the amount of hot water that comes out is large, making both C and C longer. This method has the disadvantage of not only having to discard a large amount of water and waiting time θ) but also being uneconomical.

[Invention Q) Purpose]

The purpose of the present invention is to improve the rising characteristics of hot water, namely:
When starting the bath, C1 means less water to be thrown away, and C2 means less water is thrown away when waiting.

[Outlet U, 1f (7+Summary j) In other words, on the rA exchanger outlet side, the outlet hot water temperature is detected, and the outlet
When W is set to 1, - θ), the opening of the hot water passage θ) is small, so is the T6 device? From the provision of C2, the hot water start-up l) characteristics are changed to T6.

[Invention U] Implementation 1 January Invention 0) 1 Example> Figures 2 to 4 (Explanation 1 from 2)
In addition, in the 4th I Me 1, 4 detects the exit and changes the opening of the exit 5, and attempts to change the exit/JICnf adjustment. 6 is a wax thermometer; 7 is a support that supports the wax thermometer; 8 is a wax thermometer using a wax-to-tomo enclosure crystal TG; expansion and contraction υ) movement 7 is a valve 9c; 2 is a connecting rod that transmits the connection; 1o is a valve 9 6. The spring that applies force in the closing direction, lOa, is the seat, and 11 is the hot water outlet passage, and the opening degree of the valve 9 is changed.6. , and the opening degree should be such that the minimum disbursement CY can be ensured even when the valve is most closed.

, fll+ purchase, or the same as the conventional example.
- The hot water resistance is the lowest hot water resistance C. I) Slightly more BIL, or no flow. For this reason, the hot water temperature Q) can rise earlier. , after t1 time, the hot water temperature reaches the predetermined /! i'r
When the temperature reaches 1 degree, the wax thermometer 6 starts operating, and the valve 9Z is connected via the connecting rod 8! IJ1 was opened, the hot water passage was widened by 11 inches, a large amount of hot water was poured out, and after t2 hours (1 valve 9 was fully opened,
The brewed soybean becomes B, and the temperature of the hot water drops stably. Wax thermo 6 after t1 hour when valve 9 starts to open! Set the hot water temperature to a temperature that can be used for 1tl1 production.
It can be used from 1 hour later), and the waiting time Z can be shortened by ta-tl. On the other hand, until the time t1, the hot water outlet passage 11 is in a constricted state, so that the water that cannot be used and is thrown away can be reduced to a very small amount, which is economical. 1, explained with reference to FIG.
2 is a temperature detection device that detects the temperature of hot water using a thermistor, etc.;
Reference numeral 13 denotes a subsidiary device that transmits a signal from the seed detection system to the water adjustment device 14. An electromagnetic coil is an example of a water flow regulating device? Possibly the regulating valve used. The other configurations are the same as the conventional example.

Even if configuration 2 is used, the same effect as in the above embodiment can be obtained.On the other hand, in this embodiment, there is no electrical excavation.
Since J is 6, the advantage is that between t1 and t2 θ) flow can perform cut-cutting, that is, free cutting of the exit #j radius (one time).

〔Effect of the invention〕

According to the present invention C2, the outlet side C2 of the heat exchanger 4 outlet 1]
We have installed an axis alignment device for the water that detects the degree of blackness and drives the opening of the hot water pipe θ), so when waiting for hot water to come out before it can be used,
6. It is short and the waste of unusable water of this nj+ can be minimized to a minimum, so it is economical as well as convenient to use. .
