Detailed description of the invention
Fig. 1 is the gas heater structural schematic diagram of the utility model embodiment.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
The carbon deposition phenomenon of gas heater is to be attached to heat dissipation since the imperfect combustion of combustion gas forms granular carbon granules
Caused by between piece 8, once carbon distribution formation is difficult to eliminate.Heat of the carbon distribution due to being attached on cooling fin 8, after burning can be hindered
It is transmitted to cooling fin 8, so that heat can not be transmitted in the water in heat exchanger tube, eventually leads to heat transfer efficiency reduction, water heating
Output power reduce, in addition carbon distribution also result in smoke evacuation it is unsmooth, seriously affect the safety of water heater.
As shown in Figure 1, present embodiments providing a kind of gas heater reminded with carbon distribution, which includes
Combustion chamber 1, the heat exchanger 2 above combustion chamber 1, the air inlet pipe 11 for being passed through combustion chamber 1 and the waterway tube across heat exchanger 2
Road is provided with burner 3 and blower 4 in combustion chamber 1, in order to the size of regulating gas air inflow, also sets in air inlet pipe 11
It is equipped with gas ratio valve 5, combustion gas is inputted by the air inlet 12 of air inlet pipe 11, after the gas ratio valve 5 by solenoid valve control
It is passed through in combustion chamber 1；
Wherein, waterway pipe is in inverted u-shaped, includes interconnected water inlet pipe 6 and outlet pipe 7, goes back on waterway pipe
It is provided with cooling fin 8, water inlet pipe 6 is disposed with water flow sensor 62 and inflow temperature sensor 63 in water inlet 61, out
Water pipe 7 is provided with leaving water temperature sensors 72 in water outlet 71；Cooling fin 8 is arranged at intervals on the waterway tube in heat exchanger 2
On road (horizontal component of i.e. U-shaped water route pipeline), also, detectable 8 upper and lower side leeway of cooling fin is additionally provided on heat exchanger 2
The wind pressure sensor 9 of value.
It is replaced in order to facilitate the installation and removal of wind pressure sensor 9, heat exchanger 2 offers the first detection mouth in same side
With the second detection mouth, the first detection mouth is located at the position at 8 top of cooling fin, for testing the first wind pressure point at 8 top of cooling fin
P1, the second detection mouth are located at the position of 8 bottom of cooling fin, for testing the second wind pressure point P2 of 8 bottom of cooling fin, the first detection
Mouth and the second detection mouth are separately connected two test sides of wind pressure sensor 9, and when carbon distribution occurs, the first wind pressure point P1 is (separate
Blower 4) pressure value can reduce, and the second wind pressure point P2 (close to blower 4) can be increased.
The present embodiment realizes that carbon distribution is reminded using above-mentioned gas heater, and the control method which reminds includes as follows
Step:
(1), Initialize installation, electric-controlled plate record the water heater original negative charge values Φ that full load is burnt when leaving the factoryx, together
When, record the pressure difference initial value P that the wind pressure sensor 9 when full load is burnt when dispatching from the factory detectsx；
(2), in actual use, electric-controlled plate calculates current loads value Φ of the water heater when full load is burnt to water heateri
With current pressure difference Pi；
(3), current value and initial value compare, and judge whether to meet condition: Φi<A×ΦxAnd Pi>B×Px, wherein A and
B is constant, preferably, the value range of constant A is 0.85~0.9, the value range of constant B is 1.1~1.2；As met
Above-mentioned condition, then water heater issues the prompting for having carbon distribution；If not, return step (2), continues to monitor current loads value Φx。
It in order to react in time when carbon distribution occurs, and avoids influencing user experience, wherein the value reaction of A
The severity of carbon distribution may cause that carbon distribution is very serious, and machine is sent out not yet if A value is too small (less than 0.5)
It alarms out, causes machine breakdown and can not repair；And if A value is too big (being too close to 1), as long as a little carbon distribution will be sent out
It alarms out, warning sensitivity is too high, will affect user experience；The value of different gas heater A and B is different, can pass through
The occurrence for determining A and B is tested, in the present embodiment preferably, A=0.9, B=1.2 are relatively reasonable.
For water heater when full load is burnt, the electric current of gas ratio valve 5 is maximum, at this time load value Φ (hot water device it is defeated
Power out) calculation formula be Φ=(Tout-Tin) × Q/25 (original negative charge values ΦxWith current loads value ΦiAll calculated with this
Formula), wherein ToutFor leaving water temperature, TinFor inflow temperature, Q is the water flow that water flow sensor detects；This formula
It can be understood as gas heater and hot water amount to flow out per minute when 25K, the output power of hot water device converted into temperature rise.
Water sensor 62, inflow temperature sensor 63, water outlet is arranged in water inlet 61 in the gas heater of the present embodiment
Leaving water temperature sensors 72 are arranged in mouth 71；The wind pressure sampling point setting up and down of cooling fin 8 of heat exchanger 2 connects wind pressure sensor 9,
For testing the leeway of about 8 cooling fin.Gas heater in use, only can make gas heater there are two types of situation
Output power be greatly lowered, one, occur carbon distribution, two, air pressure is insufficient；By load value to be compared with original negative when dispatching from the factory
Charge values, confirmation output power are greatly lowered, and are then proved to be carbon distribution by pressure difference value variation again, because user family
Air pressure reduction is not in pressure difference value variation.The present embodiment can just detect gas heater at carbon distribution formation initial stage
There is carbon deposition phenomenon, and realize that automatic alarm prompts, carries out carbon distribution cleaning in time, avoid carbon deposition phenomenon from deteriorating, improve water heater
Safety in utilization extends the service life of equipment.
