Embodiment Construction

[0038] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0039] In addition, if there are descriptions involving "first", "second" and so on in the embodiments of the present invention, the descriptions of "first", "second" and so on are only for descriptive purposes, and should not be interpreted as indicating or implying Its relative importance or implicitly indicates the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features. In addition, the meaning of "and / or" appearing in the whole text includes three parallel schemes, taking "A and / or B" as an example, ...

Abstract

The invention discloses a premixing device and a gas water heater, and the premixing device comprises a shell and a turbulent flow assembly; the shell is provided with an air inlet, an air outlet and a premixing chamber communicated with the air inlet and the air outlet; the turbulent flow assembly is arranged in the premixing chamber and comprises a barrel, a first turbulent flow blade and a second turbulent flow blade, the two ends of the barrel communicate with the premixing chamber, the first turbulent flow blade is arranged in the barrel, the second turbulent flow blade is arranged between the barrel and the shell, and the installation direction of the first turbulent flow blade is opposite to the installation direction of the second turbulent flow blade. The rotating direction of airflow passing through the first turbulent flow blade is opposite to the rotating direction of airflow passing through the second turbulent flow blade. According to the premixing device, fuel gas and air can be mixed more uniformly, and the premixing device is simple in structure and small in wind resistance.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to a premixing device and a gas water heater. Background technique [0002] At present, in order to make the combustion effect of the gas water heater better, the air and gas combusted on the burner generally need to be mixed through a premixing device before flowing to the burner. The premixing device on the existing gas water heater is usually a large mixing chamber, so that the gas and air flow into the mixing chamber from one inlet respectively. Due to the sudden increase of the flow space of the gas, the air and the gas diffuse to the surrounding and mix together. , the mixed gas flows out from the outlet. In this type of premixing device, since the air and gas are completely mixed by the diffusion from a small space to a large space, the uniform mixing of the air and gas cannot be guaranteed, especially when the flow rate of the air and gas is large, it will There ...
