Description

Gas heater forced-ventilated self-compensating type flue

The utility model is the used flue of combustion apparatus, particularly a kind of gas heater forced-ventilated self-compensating type flue.

At present, in the northern China city, the employed water heater of most of families is " straight-line water heater " and " chimney flue type " gas heater.Existing " straight-line " gas heater in use, anthracemia in case take place in the ventilation of must windowing in the waste gas collection chamber that produces.Because north of china in winter cold, the resident family that uses " straight-line " water heater is in order to prevent that in the too much cold air inlet chamber, when bathing, that often window is opened is very little, and the individual families ventilation of even not windowing is arranged.Because sluggish in air circulation, using water heater in this case for a long time is danger close, and the anthracemia phenomenon very likely takes place.And " chimney flue type " gas heater occurs for addressing this problem just, and it is that a flue is installed on water heater, and its designing requirement is that the flue end is installed in roof-zone of positive pressure, by flue will burn generation hot waste gas enter outdoorly along flue.The ventilation of need not windowing like this, in use.But people conveniently are installed in flue outside window usually in order to scheme.Because when wind was big, the flue outlet outside window formed negative pressuren zone, and then the formation air pours in down a chimney.Use " chimney flue type " water heater under this situation, the waste gas of its generation can not enter outdoor, in the large quantity of exhaust gas collection chamber, anthracemia takes place easily also.

The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of not only waste gas can have been entered by force outdoor, but also outdoor fresh air can be sent into indoor and sufficient combustion, can guarantee the gas heater forced-ventilated self-compensating type flue of personal safety.

The utility model is achieved in that

It has one one end is the flue collector of bend, lower end at bend is connected with exhaust fume collecting hood, its special character is, the other end at flue collector is connected with the threeway of dispatch wind, corresponding exhaust outlet position is equipped with the flue deep bead by bearing pin in the threeway of dispatch wind, corresponding flue deep bead lower position is equipped with ventilating fan in the threeway of dispatch wind, along continuous straight runs is placed with ajutage in flue collector, one end of said ajutage is drawn by air-supply outlet on the flue collector, the other end is introduced corresponding air-supply entry position in the threeway of dispatch wind, and seal by rubber cushion between the air-supply outlet on ajutage and the flue, there is barrier support corresponding air-supply entry position on ajutage, on barrier support, the ajutage deep bead is installed by bearing pin, said ajutage keeps out the wind and is fixed with the magnetic conduction iron block on the pipe, corresponding ajutage deep bead top position is fixed with electromagnet in ajutage, and there is a surface to have the rectangle inside edge of passage in the exhaust fume collecting hood bottom, a following socket is arranged on the inside edge, and said socket left and right sides side wall lower ends down is the teeth shape.

Advantage of the present utility model is:

By being installed in the ventilating fan of flue exhaust outlet below, waste gas can be discharged by force outdoorly along flue, and because the effect of the passage on the exhaust fume collecting hood, but string is unstable on the fire resistant; Simultaneously, by ajutage to the indoor fresh air of sending into after the flue preheating, so that gas heater sufficient combustion, working stability and guarantee personal safety.

The drawing explanation:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an A-A cutaway view among Fig. 1;

Fig. 3 is a B-B cutaway view among Fig. 1;

Fig. 4 is a C-C cutaway view among Fig. 1;

Fig. 5 is a D-D cutaway view among Fig. 1.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

As shown in the figure, the flue collector 2 that it is bend that the utility model has a left end, peg graft in the lower end of bend or be welded with exhaust fume collecting hood 1, there is a surface to have the rectangle inside edge 1A of passage 1a in exhaust fume collecting hood 1 bottom, the following socket 1B that an extension is downwards arranged on the 1A of inside edge and coincide with water heater fin edge, said socket 1B left and right sides side wall lower ends down is the teeth shape.The other end at flue collector 2 is plugged with dispatch wind threeway 5, in dispatch wind threeway 5 corresponding exhaust outlet 5A position have two pedestals 5 ', pedestal 5 ' on bearing pin 7 is installed, two semicircle flue deep beads 6 are installed on bearing pin 7,9 and deep bead 6 edges ride on the exhaust outlet 5A, corresponding flue deep bead 6 lower positions are equipped with ventilating fan support 11 by screw in dispatch wind threeway 5, on ventilating fan support 11, ventilating fan 10 is installed by screw, along continuous straight runs is placed with ajutage 4 in flue collector 2, one end of said ajutage 4 is drawn by air-supply outlet 2A on the flue collector, the other end is a bend pipe 4 ' and introduce corresponding air-supply inlet 5B positions in the dispatch wind threeway 5, on air-supply outlet 2A, place rubber cushion 3, sealing between the air-supply outlet on ajutage 4 and the flue, the bend pipe 4 of ajutage 4 ' on corresponding air-supply inlet 5B position barrier support 14 is arranged, bearing pin 15 is installed on barrier support 14 and ajutage deep bead 16 is installed by bearing pin 15, two grooves are arranged on the ajutage deep bead, in this groove, be installed with magnetic conduction iron block 17, by screw electromagnet stent 12 is installed in bend pipe 4 ' interior corresponding ajutage deep bead 16 top positions, tighten intrinsic U type electromagnet 13 at electromagnet stent 12, said ventilating fan 10 and electromagnet 13 connect gauge tap by the lead of drawing flue, by support rain cover 8 is being installed also on the corresponding exhaust outlet 5A in the dispatch wind threeway 5

When actual installation, gauge tap is connect near the metope that is installed in behind the power supply water heater, with exhaust fume collecting hood 1 stretch into water heater suitable for reading in and socket 1B is inserted into fin edge in the water heater and the teeth on the socket 1B are inserted in the gap of the superiors' water pipe, at this moment, inside edge 1A rides on the water heater upper edge just, and dispatch wind threeway 5 extraction windows are outer and pass through stent support.When using water heater, close a switch 18 earlier, then ventilating fan 10 is started working, and flue deep bead 6,9 is opened, and makes gap, the exhaust outlet 5A of the waste gas of water heater generation through exhaust fume collecting hood 1, flue collector 2 and ajutage 4, discharges outdoor; Electromagnet 13 gets simultaneously, with 17 adhesives of magnetic conduction iron block, ajutage deep bead 16 is opened, because in indoor is negative pressuren zone, outdoor fresh air is entered in the ajutage 4 through air-supply inlet 5B, and behind the heating by the exhaust gases in flue collector 2, send into indoor, so that water heater fully burns, guarantee personal safety, can prevent again indoorly turning cold because of ventilation.After using the back water heater, press gauge tap 18, then cut off the electricity supply, ventilating fan 10 stops operating, and flue deep bead 6,9 falls and rides on the exhaust outlet 5A, in case air intake in the flue collector, simultaneously, because of electromagnet 13 dead electricity, make card that deep bead 16 falls to the ajutage bottom along last, in case air intakes in the ajutage 4.
