Description

Outdoor gas water heater structure improvement

This creation is about the structural improvement technology of gas water heaters, especially the improved technology for the windproof and rainproof structure of outdoor gas water heaters.

As shown in FIG. 1 , the structure of the general outdoor gas-fired water heater mainly includes a casing 10 composed of a front and a rear casing, a burner 20 is disposed in the casing 10, and a water tank is connected above the burner 20. 30. On the upper side of the water tank 30, a windproof cap 40 is adopted on both sides of the top surface. The windproof cap 40 is ventilated to form an exhaust port 41, and an exhaust port 42 is also formed at the top of the water tank 30. A plurality of exhaust strip holes 101 are defined on the shell surface of the exhaust port 41, and a circular hole 102 is formed in the top surface of the housing 10 relative to the exhaust port 42; thereby the windproof cap 40 allows passage after combustion Part of the exhaust gas after the water tank is exhausted from the exhaust port 41 and discharged to the outside through the exhaust strip hole 101, and the remaining rising exhaust gas is guided by the top inclined surface and discharged from the exhaust port 42 through the circular hole 102 to the outside.

The above-mentioned conventional outdoor gas water heater still cannot achieve an effective windproof performance in the windproof function, and is almost zero in terms of the rainproof function, because such a structure has a better exhaust function at best, but is placed at the same time. Outdoors, it is necessary to directly face the outdoor wind and rain, and perhaps there is a balcony, but after all, it is outdoors, there will always be a large wind or a large rain, so this outdoor type gas water heater windproof cap 40 The wind-proof effect of the open exhaust ports 41, 42 must be greatly reduced, and the effect of rain-proof splashing is almost ineffective. This shows that this kind of conventional outdoor Gas-fired water heaters are still unsatisfactory in terms of wind and rain protection, and there is a need for improvement.

The main purpose of the improvement of the outdoor gas-fired water heater structure is to solve the above problems of the conventional outdoor gas-fired water heaters, which are not ideal for wind and rain protection, and can greatly improve the wind and rain resistance of the outdoor gas-fired water heater. Upgrade to increase its usefulness.

The structural improvement of the outdoor gas-type water heater of the present invention is sufficient to achieve the foregoing purpose, and the improved feature is that a water-permeable exhaust port is formed on the top of the water tank in the water heater casing, and the top plate is slightly curved on both sides. The exhaust hood is provided with an upwardly and inwardly inclined baffle on the bottom edges of the exhaust ports on both sides, and an exhaust section composed of a plurality of exhaust strip holes on the left and right sides of the front and rear casings And each of the exhaust sections is provided with a cover that is open and closed; and the top plate of the arc-shaped type on both sides of the exhaust cover can fully and effectively pass the hot air generated by the burner in the water heater. After the heat exchange of the water tank, the excess exhaust gas is discharged to the outside through the exhaust passages on the left and right panels of the casing, and the shielding cover on the exhaust section can prevent the crosswind from being blown back. In addition, it has the function of blocking the splash of rainwater. In addition, the baffle provided at the bottom edge of the exhaust port on both sides of the exhaust hood can effectively guide the airflow that may be generated by the outside air from the exhaust zone. Discharge to the exhaust port on the opposite side.

Referring to Figures 2 to 4, the structural improvement of the outdoor gas-fired water heater mainly comprises a casing 10 composed of a front and a rear casing, a burner 20 is arranged in the casing 10, and a water tank is connected above the burner 20. 30, and a hood 50 is disposed above the water tank 30; the exhaust hood 50 forms an air vent 501 on both sides, and the top plate 51 is slightly upwardly curved on both sides, and the vents on both sides The bottom edge of the 501 is provided with an upwardly and inwardly inclined baffle 52, and the left and right sides of the front and rear casings 10 are provided with an exhaust section 11 composed of a plurality of exhaust strip holes 101, and Each of the exhaust sections 11 is provided with a shutter 60 that is open and closed.

As described above, by designing the top plate 51 which is slightly curved on both sides of the ventilating cover 50 of the present invention, the exhaust gas generated by the burner 20 in the water heater can be sufficiently and efficiently exchanged with excess exhaust gas after heat exchange through the water tank 30. The exhaust 501 on both sides of the casing is further discharged to the outside through the exhaust section 11 on the left and right panels of the casing 10, and the shield 60 on the venting section 11 has the function of preventing the crosswind from being blown back. The function of blocking the splash of rainwater; in addition, the baffle 52 provided at the bottom edge of the exhaust port 501 on both sides of the exhaust hood 50 can effectively guide the airflow that may be generated by the venting section 11 from the venting section 11 It flows to the exhaust port 501 on the opposite side and is discharged.

The above description is only for the specific embodiments of the present invention, but the present invention is not limited to the embodiments, and those skilled in the art can make various equivalents without violating the spirit of the present invention. Modifications or substitutions are intended to be included within the scope of the appended claims.
