[summary of the invention]
The objective of the invention is to be to provide a kind of water heater with higher thermal efficiency.
Another object of the present invention is to be to provide a kind of water heater, can import auxiliary air and flow to the combustion chamber, so that reach completing combustion, and can reduce simultaneously the temperature of internal channel internal face, and then prolong the service life of water heater.
A further object of the present invention is to be to provide a kind of water heater, and the hot water with equilibrium temperature can be provided.
Another purpose of the present invention is to be to provide a kind of water heater, in the time of can allowing two or more taps use simultaneously, also can not produce the situation of pressure drop.
Of the present invention time a purpose is to be to provide a kind of water heater, but the automated cleaning incrustation scale, to prevent the accumulation of water dirt.
Another object of the present invention is to be to provide a kind of water heater, and wherein condensate water will be collected in the interior end of heat exchanger, and can evaporate voluntarily when water heater working, discharges in company with flame gas then.
In order to achieve the above object, the invention provides a kind of water heater, it is characterized in that: comprising:
One heat exchanger is provided with a first passage and a second channel, and this second channel is to be communicated with this first passage;
One burner is installed in this first passage;
One pushes air blast, is provided with an outlet and is connected to this burner, enters this burner with forced air; And
One catch basin is the periphery that is installed on this heat exchanger;
During the igniting of this burner, this advances air blast just can start, and forced air enters this burner, and and then force combustion gas flowed into by this first passage, and then flow out by this second channel.
Described water heater is characterized in that: also comprise a top board, this top board is to be installed on this first passage.
Described water heater is characterized in that: this catch basin is around the periphery that is installed on this heat exchanger.
Described water heater is characterized in that: several flame tubes are set in this second channel.
Described water heater is characterized in that: be provided with baffle plate in this flame tube.
Described water heater is characterized in that: this first passage is the inside that is arranged at this heat exchanger, and this second channel is the outside that is arranged at this heat exchanger.
Described water heater is characterized in that: also comprise and pump air blast, this is pumped air blast and is provided with an inlet, and this inlet is connected to this second channel, so that combustion gas is extracted out by this second channel.
Described water heater is characterized in that: also comprise an exhaust chamber, this exhaust chamber is the top that is arranged at this second channel.
Described water heater is characterized in that: this catch basin coats the bottom of this heat exchanger, and is connected with a water inlet.
Described water heater is characterized in that: this catch basin is provided with a recessed interior end.
In sum, water heater of the present invention not only can improve the thermal efficiency, also have simultaneously prolong water heater service life, leaving water temperature is stable, reduce manufacture cost and other advantages.

[specific embodiment]
At first see also Fig. 1 and Fig. 2, water heater 100 of the present invention comprises that mainly a heat exchanger 1, a burner 2, push air blast 3, and pump air blast 4, reach a top board 5.As shown in Figures 3 and 4, heat exchanger 1 is a cylinder body, and its middle body is provided with an inner cylindrical passage 11, reaches an annular outer tunnel 12, and annular outer tunnel 12 then is communicated with round inner cylindrical passage 11 and with inner cylindrical passage 11.Several flame tubes 13 are to be arranged in the annular outer tunnel 12, as shown in Figure 4.The top of flame tube 13 is provided with an exhaust chamber 15.The outside of heat exchanger 1 is provided with a catch basin 14 with water storage.Catch basin 14 is the bottoms that surround heat exchanger 1, and has indent bottom, is equipped with several baffle plates 131 with the flow velocity of combustion gas flame in flame tube that slow down in each flame tube 13 inside.Burner 2 is to be installed in the inner cylindrical passage 11 of heat exchanger 1.Pushing air blast 3 is the tops that are installed on heat exchanger 1, and is provided with outlet extension binding downwards burner 2.Pumping air blast 4 also is the top that is installed on heat exchanger 1, and is linked to exhaust chamber 15.Top board 5 is the tops that are installed on inner cylindrical passage 11, and is provided with several auxiliary air inlets 51, so that air is introduced inner cylindrical passage 11.Catch basin 14 is to be connected to a cold water inlet 143, and the top of catch basin 14 then is provided with a hot water outlet 142, as shown in Figure 3.
When burner 2 opened and used, air at first mixed according to correct proportions with the combustion gas meeting, and burning completely is provided then, and can avoid the generation of pernicious gas.At this moment, push air blast 3 just start to carry air to burner 2, so that a large amount of oxygen of combustion to be provided, and force combustion gas to flow downward along inner cylindrical passage 11, pump then start simultaneously of air blast 4, combustion gas is upwards extracted out along flame tube 13, and then discharge exhaust chamber 15.When combustion-gas flow during, 131 flow velocitys that can reduce combustion gas of baffle plate through flame tube 13, rest on time in the flame tube 13 to prolong combustion gas as far as possible, and then effectively the heat delivery of combustion gas to flame tube 13, flame tube 13 then again heat delivery to catch basin 14.Catch basin 14 is around the periphery that is arranged at flame tube 13, so the heat of combustion gas will can directly not escaped to atmosphere by flame tube 13.On the other hand, therefore catch basin 14 need not coat the very thick heat-barrier material of one deck in the outside of catch basin 14, so can reduce manufacturing cost also as an insulator.When pushing air blast 3 starts, can improve at the gas flow rate of inner cylindrical passage 11, therefore can reduce the pressure in the inner cylindrical passage 11, and suck air, make it enter inner cylindrical passage 11 via auxiliary air inlet 51.Via auxiliary air inlet 51 air that enter, burning completely can be provided, and can reduce the temperature of combustion gas, so that optimal heat conduction temperature to be provided, can prolong the life-span of heat exchanger in addition.In addition, condensate water can be collected in the interior end of heat exchanger 1, and automatically evaporation when water heater uses, and then discharges with flame gas, does not therefore have condensate water in the outside of heat exchanger 1, so can avoid the erosion of condensate water.
