Abstract

The invention discloses a flue assembly of a water heater and the water heater. The flue assembly defines a passage for smoke flowing, the passage is provided with a flue inlet and a flue outlet, andthe passage comprises a main body section and a contraction section; one end of the main body section communicates with the flue inlet, the contraction section is provided with a first end and a second end, the first end is in communication with the other end of the main body section, the second end is in communication with the flue outlet, the width of the first end is W1, and the width of the second end is W2; and in the cross section perpendicular to the smoke flow direction, the cross-sectional area of the first end is S1, and the cross-sectional area of the second end is S2, wherein W1 islarger than W2, and S1 is equal to S2. According to the flue assembly of the water heater, the flue assembly is arranged to be provided with the main body section and the contraction section, the width of the first end of the contraction section is larger than the width of the second end of the contraction section, the cross-sectional area of the first end is equal to the cross-sectional area ofthe second end, and therefore the structure of the flue assembly is simplified, the aerodynamic noise of the flue assembly is reduced, and the pressure loss of the flue assembly is reduced.

Description

[0001] This application is a divisional case with the filing date of "August 31, 2016", the application number of "201610783792.3", and the application title of "Water heater flue assembly and water heater" technical field [0002] The invention relates to the technical field of water heaters, in particular to a flue assembly of the water heater and the water heater. Background technique [0003] In related technologies, most of the fully premixed gas water heaters / wall-hung boilers use inverted combustion, and the flue gas generated by combustion flows from the top of the heat exchanger through the heat exchange fins to the bottom of the heat exchanger, and finally returns to the water heater / water heater from the bottom through the flue. Fireplace top exhaust. Affected by the structure of the water heater / wall-hung boiler, the flue structure is often designed to be more complicated. The complex structure has a great impact on the aerodynamic noise, and it is prone to loud ...
