Embodiment Construction

[0035] 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.

[0036] Refer below Figure 1-Figure 10 Describe the premixing device 10 of the embodiment of the present invention, the premixing device 10 can premix the gases of different media, so as to obtain a uniformly mixed gas mixture, for example, when the gas enters the combustion chamber of the gas equipment for combustion, the gas and air can be pre-mixed in the pre-mixing device 10, and the gas mixed with air and gas enters the combustion chamber for sufficient and effective combustion. The gas equipment in this article includes bu...

Abstract

The invention discloses a premixing device and gas equipment. The premixing device comprises a body which defines a gas flow channel with an air inlet and a gas nozzle; an air volume adjusting plate arranged in the air flow channel, and a plurality of normally-closed air openings and normally-open air openings which are opposite to the air inlet are formed in the air volume adjusting plate; an impeller assembly including a rotating shaft penetrating through the air volume adjusting plate and a plurality of impellers arranged on the rotating shaft, and at least one impeller is always at least partially overlapped with the projection of the normally-open air openings in the direction perpendicular to a paper surface, so that the impeller assembly is driven to rotate by virtue of air pressure; and a valve plate. According to the premixing device disclosed by the embodiment of the invention, the air volume adjusting plate with the normally-closed air openings and the normally-open air openings is arranged in the air flow channel, and the impeller assembly is driven by the air pressure to rotate so as to drive the valve plate to rotate synchronously, so that the opening degree of the normally-closed air openings is changed through the valve plate, the air inflow participating in mixing is adjusted, and a better air-fuel ratio is obtained.

Description

technical field [0001] The invention relates to the technical field of water heaters, and more specifically, to a premixing device and gas equipment. Background technique [0002] The Venturi in the related art cannot effectively adjust the gas and air, and the combustion adjustment ratio is small, so it cannot meet the gas equipment with different load demands. 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] Therefore, the present invention proposes a premixing device, which has good air-fuel ratio and strong versatility. [0005] The present invention also proposes a gas equipment with the above-mentioned premixing device, and the combustion efficiency of the gas equipment is high. [0006] The premixing device according to the embodiment of the present invention includes: a body, the body defines a gas flow channel with an air inlet and a gas nozzle; A normally...
