Smoke guide device with flow guide plate and gas water heater

Abstract

The invention provides a smoke guide device with a flow guide plate and a gas water heater. The smoke guide device comprises a machine shell, a smoke collecting hood and a draught fan and further comprises the flow guide plate used for guiding smoke and a plurality of fasteners, the flow guide plate comprises a plane plate part and extending plate parts extending out of the two side edges of the plane plate part in the length direction, and the plane plate part is provided with a plurality of smoke holes, wherein the area of the smoke holes close to the smoke inlet hole direction is smaller than that of the smoke holes far away from the smoke inlet hole direction; and each extending plate part is provided with at least two holes shaped like a Chinese character of "Min", the side wall of the smoke collecting hood is provided with at least four assembling holes, the fasteners penetrate through the holes shaped like the Chinese character of "Min" and then are locked in the corresponding assembling holes, and after the flow guide plate is assembled, gaps are formed between the two side edges of the plane plate part in the width direction and the side wall of the smoke collecting hood. Compared with the prior art, due to the arrangement of the flow guide plate for guiding the flow of the smoke , the flow of the smoke flow can be guided, so that the flow of the smoke flow is in a balanced state, the smoke can be smoothly discharged at a uniform flow speed, and the service life of the gas water heater is prolonged.

Description

technical field [0001] The invention relates to a smoke guiding device provided with a deflecting plate and a gas water heater thereof. Background technique [0002] At present, there is a smoke guiding device in the prior art, such as figure 1 As shown, the black arrow in the figure represents the flow direction of the flue gas, including the casing 10, the smoke collecting hood 20 and the fan 30, the casing 10 has a machine cavity part 100, and the smoke collecting hood 20 and the fan 30 are all arranged on the The machine chamber part 100 , the inclined wall hole of the smoke collecting hood 20 communicates with the smoke inlet hole 300 of the fan 30 , and the smoke outlet hole 301 of the fan 30 communicates with the top of the casing 10 . The existing problems are: limited by the structure, the gas water heater using the aforementioned smoke guiding device tends to accumulate at the corners during the flow of flue gas and generate condensed water, which makes the flow o...

AI Technical Summary

Problems solved by technology

The problem is: limited by the structure, the gas water heater using the aforementioned smoke guiding device tends to accumulate at the corners and generate condensed water during the flow of flue gas, which makes the flow of flue gas flow unbalanced, and the flue gas The discharge is not smooth and the flow rate is not uniform, which shortens the service life of the gas water heater
