Abstract
The invention relates to a throttling method for a water flow heating device and aims to enable cold water drained when the water flow heating device initially operates to be greatly reduced and improve the heating speed of hot water so as to fulfill the double aims of throttling to save water and saving gas energy. According to the method, a water temperature detector is arranged at the water outlet end of the water flow heating device and a flow regulator capable of regulating the flow is arranged at the water inlet end of the water flow heating device; when the water temperature detector detects that an outlet water temperature is in a cold water state in the initial period of use of the water flow heating device, the water flow heating device can be regulated to discharge water under small flow by the flow regulator so as to accelerate the heating operation; when the water temperature detector detects that the outlet water temperature reaches or is close to a set value, the flow regulator can be driven to supply water under normal large flow, so that the cold water drained when the water flow heating device initially operates can be greatly reduced and heating time is shortened to save gas energy.
Description
Technical field
The throttling method of current heater of the present invention, is useful in the Instant heating type current heater such as gas heater or electric heater, can significantly reduce the cold water that when running at current heater initial stage emits, and reaches the object of water-saving.
Background technology
Current heating system is probably divided into Instant heating type heating system and heat accumulating type (heat storage type) heating system.Wherein heat accumulating type heating system is that cold water is first stored in a heating boiler, opens use in the time that cold water is heated to uniform temperature again; Although this heat accumulating type heating system can once provide a large amount of hot water, because firing rate is slow, and it is can be slowly cooling and cause the wasting of resources to stop heating rear water temperature, so mostly use the place such as industry or restaurant that uses in a large number hot water at needs.
Compared to heat accumulating type heating system, Instant heating type current heating system is to open after hot water tap user, just starts current to heat; For example general home-use gas heater or electric heater etc. all belongs to it.Its heating means normally utilize a current detection switch detecting current while starting to discharge, when namely user opens hot water tap's draining, just drive electric heating or gas heating module to start the current heating by heat exchange module.
In above-mentioned Instant heating type current heating system, although the distance of being heated that can extend current by the coiling water channel design of heat exchange module, has the fast advantage of firing rate, before the temperature that may use in the heated arrival of current, still can emit a large amount of cold water, cause the waste of water resource.This situation is more obvious when lower in cold weather, water temperature, user is often opening after hot water tap, needs constantly first to emit cold water, and touching test water temperature, until the required temperature of the heated arrival of water temperature could normally be used, water resource is caused to quite large waste.
Because the situation of above-mentioned water resource waste, the numerous and confused method that proposes various improvement of many dealers, the such as Patent Case such as TaiWan, China TW M349998, TW M443146, is mainly to allow the cold water that cannot use first be discharged in water butt be separately used as him.Store but the cold water that these methods just negatively cannot be used is temporary transient, if can not effectively utilize, still cannot allow the cold water being discharged reduce, reach real water-saving object.
In addition, for example TaiWan, China TW M326140 case is mentioned, and while opening hot water tap, allows cold water be recycled to heat exchanger heats.The problem of this design is, when open water tap, because not yet arriving design temperature, water temperature cannot flow, if now will allow the water circulation in closing pipe line circulate, not only to change the circuit design of whole current heating system, also need to use extra pressue device, and the starting switch operating for user.Thus, not only inconvenient in the use, also increase the cost that pressue device and pipeline redesign, especially pressue device need to consume extra electric energy in the time of running, be exactly to reduce displacement to increase power consumption in brief, this method is for obviously there is no any gain effect on the environmental protection subject of broad sense.
Summary of the invention
Because the variety of issue of prior art, main purpose of the present invention is to provide a kind of throttling method of current heater, the cold water that is intended to discharge while allowing the current heater initial stage operate can significantly reduce, and accelerate the firing rate of hot water, with the dual purpose of reaching throttling water-saving and saving gas energy.The small-large flow that particularly only need switch choke valve when the invention process supplies water, and spent electric weight is quite few, and does not need to change the original circuit design of current heater, allows user maintaining under former use habit, effectively reach the object of water-saving.
