Description

Wind-proof structure of gas heating water heater

Technical Field

The utility model relates to a split type room gas heating system, especially a gas heating water spit of fland structure of preventing wind.

Background

With the improvement of the living standard of people, people tend to stay at home in summer, hot winter and cold winter areas in south. However, due to the climate characteristics in the south, the heating needs in the south are divided into time and space. Therefore, the relatively expensive household central heating system in the market is difficult to popularize in the south due to the defects of large system, high price, complex construction, high maintenance cost, incapability of quickly responding to heating demands and the like, and people need a split type small heating system which can quickly respond, is economical in price, has low power and can be installed in a single room. The Chengdu Yasi European technology limited company has developed split room heating system first, and like split air conditioner by outer machine gas heating water spit and inner machine heat dissipation radiator constitute, the outer machine supplies the return water nozzle stub to connect through wearing the wall, the system is small and exquisite slim and graceful, the installation is simple, energy-efficient, economical and practical. The gas heating water heater in the system is generally hung on the outer wall of a room to be heated or placed on a windowsill, and in the practical process, the combustion system is found to be easily affected by wind to cause flameout, so that the small heating system cannot work normally and continuously, the design with the windproof function needs to be additionally arranged on the heating water heater, and the requirements of simple structure, reliable effect, economy and practicability need to be met.

Disclosure of Invention

In order to realize the purpose, the utility model discloses the technical scheme who takes does: the horizontal straight-through smoke exhaust of the Yasi European gas heating water heater is designed to be composed of a smoke exhaust tube, a wind shield cap and an induction chamber, the smoke exhaust tube penetrates through the induction chamber from the right side, the wind shield cap is arranged in front of an outlet of the smoke exhaust tube, the wind shield cap is formed by folding a rectangular metal sheet into two pieces with different lengths, the wind shield cap is arranged outside one side of the convex wind shield cap, the wind shield cap is additionally arranged at the outlet of the side of the smoke exhaust tube, and the wind shield cap is arranged in the middle of the induction chamber.

The utility model has the advantages that: simple structure, low cost and good effect.

In the figure, 1, a smoke exhaust tube, 2, a wind shield cap, 3, an induction chamber, 4, a hot water heater shell, 5, a smoke collecting hood, 6, a smoke chamber, 7, a heat exchanger, 8, a combustion furnace end, 9, a side smoke outlet and 10, a rear smoke outlet are arranged.

Detailed Description

In order to make the technical field person understand the scheme of the present invention better, the following will combine with fig. 5 in the present embodiment to clearly describe the technical scheme in the embodiment of the present invention.

And (4) description of normal working conditions. With reference to fig. 1-4, fig. 5, when the water heater normally works, the flue gas generated by the burner 8 rises to the smoke collecting hood 5 through the flue gas chamber 6, turns left into the smoke exhaust tube 1, fig. 5, enters the induction chamber 3 from the direction a, and under normal conditions, the flue gas passes through the channel between the wind blocking cap 2 and the induction chamber 3 along the line a, passes around the points F and G, and is discharged from the side outlet 9 and the rear outlet 10 through the areas D and E. According to the Bernoulli principle, negative pressure is formed at a narrow passage between the windshield cap 2 and the induction chamber 3, and smoke can be smoothly discharged under the action of hot pressing.

B, explanation of the working condition of the windward. When wind from the B direction exists, the oG arm oF the windshield cap 2 is longer than the oF arm, the wind pressure is high, the windshield cap 2 rotates anticlockwise along the point o, the point G touches the point G', the wind from the area D is blocked, and the part oF the wind is prevented from flowing backwards into the combustion chamber along the reverse direction oF the A direction through the smoke exhaust tube 1 to blow out flame, so that flameout is caused. On the other hand, due to the anticlockwise rotation, the section of a channel formed between the end F of the windshield cap 2 and the induction chamber 3 is enlarged, and the exhaust of smoke is facilitated; meanwhile, the wind coming from the B direction is induced to flow to the rear smoke outlet 10 through the oF arm oF the windshield cap 2 in the E area, the wind speed is accelerated due to the narrowing oF the channel in the E area, negative pressure is formed, and then the smoke flowing to the rear smoke outlet 10 is further sucked and discharged more smoothly.

And C, explanation of the working condition of the windward. When wind from the direction C exists, the wind acts on an oF arm oF the windshield cap 2, the windshield cap 2 is forced to rotate clockwise, so that the end F reaches the point F', the situation that the incoming wind flows back into a combustion chamber along the reverse direction A through the smoke exhaust tube 1 to blow out flame to cause flameout is prevented, and at the moment, the incoming wind flows out from a side smoke outlet 9 through the area E. On the other hand, due to clockwise rotation, the section of a channel formed between the G end of the windshield cap 2 and the induction chamber 3 is enlarged, which is beneficial to discharging smoke; meanwhile, when the wind coming from the C direction is discharged from the side smoke outlet 9, negative pressure is formed, which is beneficial to discharging smoke.

The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
