The specific embodiment

See also shown in Figure 1, in illustrated forced exhaust water heater, inner inlet and outlet pipe 10 comprises a water inlet 11 and a delivery port 12, be provided with a current inductive switch 13 near water inlet 11 places, be provided with a temperature sensor 14 near 12 of delivery ports, and pipeline 10 is provided with heat dump 15, then predeterminable air exhauster 16 and flue 17 above pipeline heat dump 15, an and air door inductive switch 18 of being located at floss hole, simultaneously be provided with burner 20 below pipeline 10, burner 20 is made up of a plurality of burning jambs 23 and gas distribution pipe 21.

In the utility model, the burner 20 of this forced exhaust water heater inside is divided into two groups, is made up of gas distribution pipe 21 ' and top burning jamb 23 ' and gas distribution pipe 21 " and top burning jamb 23 " thereof respectively.These two groups of burners are connected with set magnetic valve P1, the P2 in fuel gas inlet place 25 respectively, thereby control air inflow according to the water temperature height.In this embodiment, two groups of burners comprise eight burners and six burners respectively.

Especially, in the utility model, magnetic valve P1 and P2 are by an automatic segmentation control device 30 controls, and this automatic segmentation control device 30 as shown in Figures 2 and 3.As seen from the figure, this control device 30 comprises: in order to amplifier A, back level comparator A1, A2, the A3 in order to receive described amplifier voltage signal, a plurality of resistance R 1, R2, R3, the R4 that is used to form different dividing potential drops that receives described temperature sensor water temperature voltage signal, and a central microprocessor 32.In above-mentioned control device embodiment, thereafter the relevant action of level comparator A1, A2, A3 and two magnetic valve P1, P2 as shown in Figure 3, wherein P1, P2 are 0 o'clock, the expression closed electromagnetic valve, P1, P2 are 1 o'clock, the expression magnetic valve is opened.

Preferably, above-mentioned control device 30 also comprises and is used to control air exhauster 16, air door inductive switch 18, current inductive switch 13.

The course of work of above-mentioned control device below is described in detail in detail: when using water heater, the current inductive switch 13 of water inlet 11 is connected, air exhauster 16 entrys into service, so air door inductive switch 18 is connected, two magnetic valve P1, P2 open immediately, to 21 while of two ends coal gas distributing pipe air feed, igniter is lighted combustion gas.This moment, 14 burners 23 burnt simultaneously, and the temperature sensor 14 that is installed in water heater delivery port 12 places is sent the water temperature voltage signal into the A amplifier, and its voltage outputs to back level comparator A1, A2, A3 (referring to Fig. 2) after amplifying.Because the benchmark voltage of A1, A2, A3 is depressed at the branch of resistance R 1, R2, R3, R4 and is had nothing in common with each other, be V1＞V2＞V3, therefore along with leaving water temperature raises gradually, then A1, A2, A3 output state also become one state by " 0 " state gradually successively, otherwise return successively.The voltage signal of A1, A2, A3 output is sent into central microprocessor 32 and is carried out the data processing, is determined the switch of two magnetic valve P1, P2 then by central microprocessor 32.Because of each burner quantity difference of comprising of group burner 20, when leaving water temperature is lower than 42 ℃, two magnetic valve P1, P2 standard-sized sheet (referring to Fig. 4), this moment the firepower maximum.When leaving water temperature raises gradually, A3 output becomes " 1 " by " 0 ", automatically close magnetic valve P1 (referring to Fig. 5) this moment, if leaving water temperature still raises, when causing A2 output also to become " 1 ", magnetic valve P1 opens again, and closes magnetic valve P2 (referring to Fig. 6), if water temperature no longer rises and descends, then said process is return successively.Continue to rise if leaving water temperature, hydraulic pressure too small because of current is crossed factor such as low, promptly cause A1 output to become " 1 ", P1, P2 closed simultaneously and reported to the police this moment.In addition, preferably, in use, as strong downdraught (referring to that high wind is down poured in down a chimney by flue), or air exhauster 16 stall of breaking down, this moment, the air door inductive switch 18 was closed, and the utility model is in alarm state.Only otherwise reset (referring to that current inductive switch 13 opens and closes once), even water temperature has reduced or strong downdraught disappears, the utility model is in alarm state always, and etc. to be shut down or reset.

Therefore, but the utility model automatic segmentation control burning jamb makes it no matter winter or summer all can keep design temperature, like this, makes the forced exhaust water heater have stable and suitable leaving water temperature on the one hand, then can effectively save the coal gas energy on the other hand.Simultaneously, the design of this auto-control leaving water temperature also can be exempted the user from the trouble that walks to regulation and control outside the bathroom.
