Abstract
The utility model relates to a top windproof device of a water heater tank arranged at the top of the water heater tank. The utility model is mainly characterized in that the width of the cover body in the windproof device is wider than the width of the water tank, and the corresponding positions of the both sides top of the water tank in the cover body are provided with baffle plates which form an arc shape. In addition, a supported joint plate is arranged between the exhaust passage mouth of the top of the cover body and the conducting strips of the top of the water tank. The utility model has simple structure, and has the advantages that the utility model can improve the thermal performance of the water heater and prevent the flameout.
Description
The utility model includes the water heater of heat-generating device, is a kind of wind-proof device that is arranged on the water-heater water tank top.
Existing water heater generally all includes heater, combustion chamber, water tank and shell, side ring is wound with cold water pipe outside the water tank, the top is provided with heat absorbing sheet, a upper shield that has a ventilating opening is stamped on the top of water tank, cover top portion is provided with overlapping and covers the air outlet that ventilating opening is connected, the shell both sides also are provided with some openings, and it is combustion-supporting to enter the combustion chamber for fresh air.The water heater of this structure, the upper shield design is unreasonable, is that mainly it is difficult for getting rid of the gas that the combustion chamber internal combustion is crossed, and also influences the Channel Group of fresh air, cause incomplete combustion, thereby a large amount of combustion gas is accumulated in the combustion chamber, extinguishes to cause stove fire.Directly be nested with in tank top with upper shield water tank end face similar sizes because of existing water heater is this again, when the moisture content in the combustion gas is met cold and behind the water droplet that congeals at the exhaust passage mouth, water droplet promptly directly flows on the heat absorbing sheet of device in tank top, has influenced the heat absorption efficiency of heat absorbing sheet.
The purpose of this utility model is for a kind of improved water-heater water tank top wind-proof device is provided, and makes this device be easy to get rid of gas in the combustion chamber; In addition, make this device also can avoid condensing water droplet or outer inundation part to accumulate on the heat absorbing sheet, to improve the endothermic effect of heat absorbing sheet.
The utility model is achieved in that the utility model is designed to the upper shield that is arranged on the water tank top to have the lid of degassing function, for this reason, the design designs the lid width widelyer than water tank, and width is still consistent with water tank, promptly, make between the edge at the edge at lid two ends and water tank two ends and leave a segment distance, and on lid two symmetrical front and rear walls, a curved baffle plate is set corresponding to water tank edge.Like this, have the gas channel that constitutes between baffle plate that twice upwards prop from the water tank edges at two ends and lid two ends sidewall in lid, this two passes has wind-drawing effect, helps promoting the burn eliminating of back gas and the importing of fresh air.
For preventing that water heater from gathering condensate water on the heat absorbing sheet of tank top, the design can be in lid the exhaust passage mouth under establish a bearing plate, the width of bearing plate is identical with lid, so that can be connected on the front and rear wall of lid, the mediad lower recess of bearing plate and be a guide groove, and on the front and rear wall of lid therewith corresponding section, guide groove bottom have an aperture, from then on the condensate water that accumulates in the bearing plate upper rail is flowed out in the aperture, avoid accumulation of condensed water on heat absorbing sheet.The condensate water that flows out from aperture is when the lid lateral wall flows down, again the heating of burned chamber and distributing.
Therefore, the utility model has the advantages that because lid is wideer than water tank, again in water tank both sides of the edge Position Design baffle plate, make that both sides have formed an air-suction channel in the lid, improved the exhaust performance of water heater, can not stop working because of vapour lock; Secondly, because of being provided with a condensed water bearing plate in the utility model, just can not gathering condensed water again on the heat absorbing sheet of tank top, thereby improve the heat absorption efficiency of heat absorbing sheet.
Embodiment of the present utility model as shown in drawings.
Description of drawings:
Fig. 1 is stereoscopic figure of the present utility model.
Fig. 2 is the position figure of baffle plate and bearing plate in the utility model.
Fig. 3 is the perspective view of the utility model device on water heater.
Fig. 4 is the aspect graph of the utility model device on water heater.
Below the accompanying drawing illustrated embodiment is described specifically.
See that by Fig. 1 the present embodiment wind-proof device is watched outside it, be one with water heater in close but the lid 1 that width is wideer than water tank of water tank width, the top has an exhaust passage mouth 11, has a through hole 12 on the positive front and rear wall.See by Fig. 2, be provided with baffle plate 2,3 and bearing plate 6 that top has arc in lid 1 inside.Baffle plate 2,3 is fixed on 1 liang of symmetrical front and rear wall of lid, the road is corresponding to the width of water tank between between this two baffle plate, the edge that makes baffle plate 2,3 just be engaged in water tank two side roof parts is also upwards propped, and then constitutes two airways 4,5 that are gap-like between baffle plate 2,3 and lid 1 left and right sides sidewall.In the present embodiment, bearing plate 6 is made the V-shaped groove structure, and such bearing plate 6 is fixed on 1 liang of symmetrical front and rear wall of lid, and the through hole 12 just opened on the aligned sidewalls of the bottom wedge angle 61 that makes V-shaped groove.
Seen that by Fig. 3 and Fig. 4 the utility model is nested with behind the water heater top, just holding is in both sides of the edge, water-heater water tank 8 top for baffle plate 2,3, and heat absorbing sheet 7 is inclusive between this two baffle plate; The V-arrangement bearing plate 6 of exhaust passage mouth 11 is positioned at the top of heat absorbing sheet 7 on the lid, then if thermal current in the passway freeze-out water droplet or by the external world during of 11 places from passway encroached water liquid, all drop on this V-arrangement bearing plate 6, and flow out lid 1 and can not influence heat absorbing sheet 7 again from V-shaped groove wedge angle 61.Because of having some openings on the outer cover of water heater, fresh air flows into water heater from these openings, just because the utility model has disposed two airways 4 and 5 in the two ends of lid 1 side-walls, then fresh air will prolong baffle plate 2,3 and upwards climb sharply, form one suction, drive and gather the eliminating of burnt gas in the combustion chamber, and then make the combustion chamber guarantee circulation of air, completing combustion has increased the discharge effect of burning and waste gas.
