Problems solved by technology

Although the combustion efficiency of the fully premixed gas combustion device is higher than that of the atmospheric gas combustion device, the mixing effect of the gas mixing tube is difficult to control, and the length of the gas mixing tube is usually not long, and the air flow and the gas flow cannot be mixed in the gas. Uniform mixing in the limited travel distance in the tube, the mixing efficiency is limited, resulting in the combustion efficiency of the combustion device cannot be further improved

Embodiment Construction

[0050] In order to illustrate the present invention more clearly, a preferred embodiment and accompanying drawings are given in detail as follows. Please refer to Figure 1 to Figure 10 Shown is a gas combustion device 100 with a gas mixer according to the first preferred embodiment of the present invention. The gas combustion device 100 is applied to a water heater as an example, and includes at least one burner 10, a gas intake assembly 12, a The blower 14 and the gas mixer 16 of this embodiment.

[0051] The at least one burner 10 is multiple and arranged along a predetermined axis X, and each burner 10 is used to burn gas to generate a flame. The gas intake assembly 12 includes a connection pipe, a solenoid valve 124, a proportional valve 126 and at least one nozzle 128, wherein the connection pipe 122 is connected to a gas source (not shown); the solenoid valve 124 is used to control opening or The gas path is blocked; the proportional valve 126 is used to adjust the ga...

Abstract

The invention discloses a gas mixer. The gas mixer comprises a main body and one or more gas outlet pipes. The main body is provided with a gas inlet portion and a gas mixing portion, wherein the gasinlet portion is provided with an air inlet, one or more gas inlets and a gas channel. The gas channel communicates with the air inlet and the gas inlets and provided with an outlet. The gas mixing portion is provided with a mixing chamber which communicates with the outlet. The gas outlet pipes are combined into the gas mixing portion of the main body and extend into the mixing chamber in a protruding manner. The outlet of the gas channel corresponds to a pipe body of the corresponding gas outlet pipe. In this way, after gas flow is fully pre-mixed with air flow, a mixture is output to burners; the air-fuel ratio can be controlled precisely; and burning efficiency of the burners is improved.

Description

technical field [0001] The present invention relates to a gas burning device; in particular, it refers to a gas mixer for mixing gas and air. Background technique [0002] The traditional atmospheric gas combustion device is to install a nozzle at the gas inlet of the burner, and use the low pressure formed around the nozzle when the gas is output from the nozzle to introduce primary air into the burner to mix with the gas, and then output the gas through the fire outlet of the burner. After the gas is ignited, a flame is formed, and when the flame burns, secondary air is introduced from around the flame to burn. Another form of gas burning device is the full premix type, which uses a blower to introduce air into the burner to mix with the gas, and output the mixed gas and air from the fire outlet of the burner. [0003] The fully premixed gas combustion device uses the gas mixing tube as the gas and air vessel to mix. The gas mixing tube uses the principle of the Venturi t...
