[0002] The fan hood used for gas water heaters in the related art usually consists of at least five plates spliced together, and a lot of angular surfaces are formed between the plates. The flow resistance of the airflow in the fan hood is relatively large, that is, it is easy to The air resistance phenomenon occurs in the fan hood, which makes the exhaust volume of the fan hood less than the intake air volume per unit time, resulting in low heating efficiency of the gas water heater

Embodiment Construction
[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0032] A gas water heater usually includes a combustion chamber, a heat exchanger, and a fan hood. The high-temperature flue gas generated by combustion in the combustion chamber defines a flue gas channel through the heat exchanger, and the high-temperature flue gas enters the flue gas channel to cool the water in the heat exchanger. After heat exchange, the low-temperature flue gas is inhaled by the fan or blown into the fume collecting hood for collection and then discharged. It should be noted that the fan hood according to t...

The invention discloses a fan smoke hood for a gas water heater. The fan smoke hood comprises a first side portion, a second side portion and a middle portion; the first side portion and the second side portion extend in a vertical direction; the middle portion is located between the first side and the second side portion; and the first side portion, the second side portion and the middle portionjointly form a smoke outlet cavity, the smoke outlet cavity is provided with a smoke inlet and a smoke outlet, and the flow channel surface of the smoke outlet cavity is a smooth curved surface. According to the fan smoke hood for the gas water heater, the flow channel surface of the smoke outlet cavity is designed into the smooth curved surface, so that airflow can be smoothly discharged, and theair resistance phenomenon is avoided.
Description
technical field [0001] The invention relates to the technical field of gas equipment, in particular to a fan hood for a gas water heater. Background technique [0002] The fan hood used for gas water heaters in the related art usually consists of at least five plates spliced together, and a lot of angular surfaces are formed between the plates. The flow resistance of the airflow in the fan hood is relatively large, that is, it is easy to The air resistance phenomenon occurs in the fan hood, which makes the exhaust volume of the fan hood less than the intake volume per unit time, resulting in low heating efficiency of the gas water heater. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems at least to a certain extent. [0004] For this reason, the present invention proposes a fan hood for a gas water heater, which can ensure the smooth discharge of smoke from the smoke chamber and avoid air resistance. ...
