In the present embodiment, flue heater 2 is the n font, connecting leg 24 in being connected with between the left side pipeline section lower position of flue heater 2 and the right side pipeline section lower position, the two ends, the left and right sides of middle connecting leg 24 are communicated with the flue that is positioned at left side pipeline section and right side pipeline section respectively and add hot-water cavity 22, are equipped with the door 25 that sweeps up dust on pipeline section top, left side and pipeline section top, right side on the flue heater 2.In the present embodiment, as shown in Figures 2 and 3, be provided with two transverse tubes 51 and two standpipes 52 in the flame chamber 11, transverse tube 51 and standpipe 52 all are positioned at the place ahead of exhanst gas outlet 112, the two ends of transverse tube 51 all add hot-water cavity 12 with fire door and are communicated with, and the two ends of standpipe 52 all add hot-water cavity 12 with fire door and are communicated with.In addition, the flame chamber 11 top walls of fire door heater 2 are provided with the protruding wall 15 of open loop of downward protrusion, the protruding wall 15 of open loop is positioned at the top that the plane intercepts heater 3 peripheries, the protruding wall 15 of open loop is the annular that has opening 151, opening 151 is towards exhanst gas outlet 112, and the wall face height at the position of close exhanst gas outlet 112 raises from front to back gradually on the protruding wall 15 of open loop.

Present embodiment in use, can insert in the radiator pipeline loop and/or with the water tank of the usefulness of having a bath and be connected, specifically when connecting, both can first water inlet pipe 13 in parallel with second water inlet pipe 32, first outlet pipe 23 is in parallel with the 3rd outlet pipe 42, also the 3rd outlet pipe 42 directly can be communicated with first water inlet pipe 13.The pipeline that is used for connecting second water inlet pipe 32 and the 3rd outlet pipe 42 adopts high temperature resistant flexible pipe.With exhaust gases passes 21 be communicated to wall with flues or heated kang on smoke inlet, fire door heater 1 is placed on stove or the gas-cooker 6.When needs are cooked, the plane is intercepted integral body that heater 3 and fire door secondary heater 4 constitute upwards takes out and is placed on other places, lay frying pan at the stove ring recess and cook, when gas-cooker was given the frying pan heat supply when cooking, unnecessary heat was absorbed by fire door heater 1 and flue heater 2., the plane is intercepted heater 3 put back on the stove ring recess with the integral body that fire door secondary heater 4 constitutes during pure heating not cooking, at this moment the plane intercepts heater 3, fire door secondary heater 4, fire door heater 1 and flue heater 2 four and absorbs energy jointly.In use for some time, referring to Fig. 1, can open two 25 pairs of flue inwalls of door that sweep up dust and sweep up dust.In the present embodiment, be used for the thermal source of heat supply to be not limited to gas-cooker, can also use coal stove, also can burning crop straws.During use, flame and hot-air enter through advancing fiery opening 111, because the plane intercepts stopping of heater 3, flame and hot-air spread apart around the plane intercepts 3 times directions of heater, and the peripheral rising of the sidewall that intercepts heater 3 on the plane, spread over again after the rising between the upside of fire door secondary heater 4 and plane obstruct heater 3, because the alteration of form of flame, flame and hot-air increase with the heat exchange area between the boiler, make energy to be absorbed by the water in each heating chamber faster.Referring to Fig. 1, because the existence of middle connecting leg 24, the water in the flue heater 2 right side pipeline sections can heat rising after middle connecting leg 24 flows to the left side, to form the circulation heating.Referring to Fig. 3, because the existence of the protruding wall 15 of open loop, the flame that intercepts heater 3 periphery risings from the plane can burn on the protruding wall 15 of open loop, circles round at the protruding wall 15 inside and outside flames that form of open loop, further improves the heat exchange effect.As shown in Figure 8, can also at the middle part the second air inlet flame-observing hole, 43, the second air inlet flame-observing holes 43 be set on fire door secondary heater 4 in the present embodiment can play the air inlet oxygen supply equally and observe the effect of the intensity of a fire.

As shown in Figure 9, the difference that the utility model plane intercepts second embodiment of burning energy-saving boiler and first embodiment is: referring to Figure 10, exhanst gas outlet 112 ' be positioned at flame chamber 11 ' top chamber wall central authorities, there is not the fire door secondary heater in the present embodiment, second water inlet pipe 32 ' pass from top to bottom fire door heater 1 ', second outlet pipe 33 ' the plane intercept heater 3 ' and flame chamber 11 ' top chamber wall between, second outlet pipe 33 ' add hot-water cavity 12 ' be communicated with fire door.So same the utility model plane that can solve intercepts burning energy-saving boiler technical problem to be solved, but in the present embodiment owing to there is not the open top of able to hold frying pan, so can not be used for cooking.In addition, present embodiment also comprise the tube connector 34 that is arranged at flame chamber 11 ' interior ', tube connector 34 ' the plane intercept heater 3 ' sidewall and flame chamber 11 ' sidepiece chamber wall between, tube connector 34 ' two ends be communicated with respectively fire door add hot-water cavity 12 ' and the plane intercept add hot-water cavity 31 ', like this, the plane intercept add hot-water cavity 31 ' interior a part of water can by tube connector 34 ' enter fire door add hot-water cavity 12 ' in.In addition, the present embodiment midplane intercept heater 3 ' go up medium position be provided with the middle part perforation 35 of up/down perforation ', like this flame can bore a hole 35 from the middle part ' be upward through.

Among two above embodiment, first water inlet pipe can also have following effect: when temperature was very low in the winter time, possible fire door added hot-water cavity and flue and adds the interior water of hot-water cavity and can be frozen in, and at this moment can by first water inlet pipe water be bled off in advance.

In the utility model in order to stop that flame is to increase heat exchange area, structure in the fire door heater can also (Figure 11 only shows the structure in the fire door heater as shown in figure 11, the flue heater is not shown in Figure 11), the difference that the utility model plane intercepts the 3rd embodiment of burning energy-saving boiler and first embodiment is: the 3rd embodiment do not have the fire door secondary heater yet, second water inlet pipe 32 " and second outlet pipe 33 " is horizontally installed on flame chamber 11 " in; second water inlet pipe 32 " and second outlet pipe 33 " all adds hot-water cavity 12 with fire door and " is communicated with, the plane intercepts and to be connected with three between the top wall of heater 3 " and flame chamber 11 " and to go up connecting legs 36 in addition "; go up connecting leg 36 and " all add hot-water cavity 12 with fire door " and be communicated with; so equally also can increase heat exchange area, the plane obstruct adds hot-water cavity 31 " interior a part of water can by last connecting leg 36 " and enters fire door and add hot-water cavity 12 ".In the present embodiment, the wall of fire door heater 1 " be positioned at plane intercept heater 3 " top is the taper of downward contraction, and is provided with the 3rd air inlet flame-observing hole 431 at the middle part ".Like this, flame can rise along the conical surface, so that the 3rd air inlet flame-observing hole 431 " in air inlet smoothly.

Above-described embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
