Description
Technical field
The utility model is related to gas instantaneous water heater technical field, more particularly, to the gas-fired quick-heating water of environmental protection and energy saving
Device technical field.
Background technology
Existing gas heater in use, has three big shortcomings：
1st, gas heater stops burning after cutting off the water, but dress interior hot water in heat exchanger portion is still absorbing heat so that use
Family is in boiling water again in use, hot water temperature drastically raises.According to National Fuel Gas water heater GB6932-2015 standards, temperature of cutting off the water
Rise and require to be less than or equal to 18K, only Some gases water heater can accomplish below 10K at present, and the higher temperature difference is very easy to cause
User scalds, so as to influence Consumer's Experience；
2nd, gas heater flue-gas temperature in low load combustion is too low, typically there was only 70-80 degree, easily produces condensation
Water, drips from water tank top, corrosion is produced to water heater inside, reduce service life；
3rd, part producer loads onto increase bypass pipe in heat exchanger portion to reduce the water cut-off temperature-rising of gas heater, but
So easily make water heater when high load capacity burns, temperature is too high above water tank, causes water heater high temperature alarm；Such as entitled combustion
Gas water heater water cut-off temperature-rising restraining device (CN01276045.5), openly (to announce) number be CN2513049Y, the applying date to be
2001.11.19 patent application, it be provided with using water flow sensing unit as input block controller, be controlled by controller
Controlled dibit water distribution valve, water inlet and controlled dibit water distribution that one delivery port is connected with the water inlet of heater cold water inlet
The cold water straight pipe that another delivery port of valve is connected, and a water inlet are connected and another with the delivery port of cold water straight pipe
Three water service pipes that water inlet is connected with the delivery port of heater hot water outlet pipe, the water inlet and cold water of controlled dibit water distribution valve
The delivery port of water inlet pipe is connected, and the delivery port of three water service pipes is connected with the water inlet of hot water outlet pipe.It is using bypass
The structure of pipe.
Utility model content
The purpose of this utility model provides a kind of effectively reduction water cut-off temperature-rising aiming at the deficiencies in the prior art, makes combustion
Gas water heater can also keep the gas heater of higher cigarette temperature when Smaller load burns.
In order to reach object above, the utility model patent is adopted the following technical scheme that：
It is a kind of to reduce cold water cut-off temperature-rising and reduce the gas heater that condensed water is produced, including with heat exchanger, burning
The gas heater main body of device, inlet and outlet pipe, it is characterised in that on the inlet pipeline increase have three water flowing proportioning valves and
Two branch roads, a branch road is connects the cooling pipeline of the outlet pipeline of gas heater, and another branch road is cold to be communicated to heat exchanger
Water lines；Three water flowing proportioning valves adjust the water of cold water pipeline and the pipeline that cools according to burning load, during underload, by cooling pipe
Road water is tuned up, and turns cooling pipeline water down during middle load burning, closes cooling pipeline water when high load capacity burns.
Compared with prior art, a kind of test system that the utility model patent is provided has the advantages that：
Employ after the utility model structure, cooling pipeline can close outlet pipe after one section with finite reduction burner device
Temperature, reduces water cut-off temperature-rising, prevents user from scalding；
The utility model improves cigarette during gas heater low load combustion by the water of the branch road of threeway energy valve regulation two
Temperature, reduces condensed water and produces, increase water heater service life.
The utility model is novel in design, compact conformation, and composition is simple, convenient and practical, especially can efficiently suppress combustion gas
There is water cut-off temperature-rising phenomenon in water heater, and user can enjoy the hot water of safety appropriateness, does not result in and scalds or uncomfortable consequence.
The utility model can be assembled in gas heater as black box, significantly improve properties of product.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation when utility model is adjusted.
Description of reference numerals：1st, heat exchanger 2, burner 3, inlet pipeline 4, outlet pipeline 5, cooling pipeline 6, cold water pipe
Road 7, three water flowing proportioning valves.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model patent.
As shown in figure 1, a kind of gas heater for reducing cold water cut-off temperature-rising and reducing condensed water generation of the present utility model,
Including with heat exchanger 1, burner 2, inlet and outlet pipe (4,5) gas heater main body, on the inlet pipeline increase
Added with three water flowing proportioning valves 7 and two branch roads, a branch road is the cooling pipeline 5, Ling Yizhi of the outlet pipeline of connection gas heater
Road is to be communicated to heat exchanger cold water pipeline 6；Three water flowing proportioning valves 7 adjust cold water pipeline 6 and cooling pipeline 5 according to burning load
Water, during underload, the cooling water of pipeline 5 is tuned up, turned the cooling water of pipeline 5 down during the burning of middle load, high load capacity combustion
Cooling pipeline 5 water is closed during burning.The three water flowings proportioning valve 7 couples with the master controller of gas heater, in two branch roads
Water flow sensor is respectively provided with, water flow sensor is electrically connected with master controller, is sentenced by master controller by the information of reception
Disconnected burning load adjusts branch road water.
Its specific works is as follows：
When the 1st, cutting off the water, because cooling pipeline has a part of cold water, the temperature of heat exchanger portion dress the inside water can be reduced,
Again during boiling water, the hot water that cooling pipeline can be also flowed out in cold water is filled with heat exchanger portion is neutralized, and reduces water cut-off temperature-rising.
2nd, during low load combustion：
Now, because cold water pipeline water is smaller, the heat exchanger portion side's of loading onto temperature is higher, and flue-gas temperature is also higher, cold
Solidifying water produces speed and substantially reduced.
3rd, during middle load burning：
Now, with the rise of load, cooling pipeline water is slowly turned down, is unlikely to the heat exchanger portion side's of loading onto temperature
It is too high and alarm, while flue-gas temperature keeps a higher temperature, the generation of condensed water is reduced, now, with the liter of load
Height, cooling pipeline is closed, and prevents that the heat exchanger portion side's of loading onto temperature is too high and alarms.
4th, when senior middle school's load burns：
Now, with the rise of load, cooling pipeline is closed, and is made the heat exchanger portion side's of loading onto temperature too high and is alarmed.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these all belong to
In protection domain of the present utility model.
