Description

Full premix fire grate structure

Technical Field

The utility model relates to a full premix fire arranges structure.

Background

The existing gas water heater can generate yellow flame when in use, and the combustion is insufficient.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a structure is arranged to full premix fire solves the insufficient problem of fire row burning.

In one or more embodiments, the ejector body is provided with a first gas mixing cavity and an ejector pipe, the first gas mixing cavity is communicated with the ejector pipe, the ejector pipe is provided with a gas inlet, the gas outlet is located on the first gas mixing cavity, so that gas is mixed in the ejector body for the first time, and when the gas enters the ejector body from the ejector pipe, the gas takes away air around the gas inlet and enters the first gas mixing cavity for the first time.

In one or more embodiments, a plurality of first air channels are arranged on the outer side surface of the first air mixing cavity, and the first air channels are arranged at intervals.

In one or more embodiments, a second air passage is arranged on the fire hood at the position of the first air mixing cavity, the second air passages are arranged at intervals, and the first air passage and the second air passage form a plurality of air passages communicated with the second air mixing cavity to form a plurality of air passages corresponding to the air outlet.

In one or more embodiments, the second air passage is located at the air inlet end of the fire hood, mounting grooves are formed in two sides of the air inlet end, and a connecting piece matched with the mounting grooves is arranged on the injection body to form connection, so that the fire hood is conveniently mounted on the injection body.

The utility model has the advantages that: make every gas outlet all have an air flue to correspond for every gas all has an air to mix, has improved the proportion of air in the gas mixture, makes the gas more thoroughly burn, improves combustion efficiency.

Detailed Description

The application scheme is further described below with reference to the accompanying drawings:

referring to the attached drawings 1-2, the full-premix fire grate structure comprises a fire grate cover 2 and an injection body 1, wherein the injection body 1 is provided with a plurality of air outlets 11, the air outlets 11 are positioned at the upper part of the injection body 1, the fire grate cover 2 is covered at the upper part of the injection body 1 and forms a second air mixing cavity 21, a plurality of combustion holes 22 are formed in the upper end surface of the fire grate cover 2, a plurality of air passages 3 communicated with the second air mixing cavity 21 are formed in the fire grate cover 2 and the injection body 1, the air passages 3 correspond to the air outlets 11, and the air passages 3 are positioned below the air outlets 11.

Preferably, the air outlet 11 is arranged on two side surfaces of the injector 1, so that the mixed gas mixed for the first time obliquely enters the second gas mixing cavity 21 through the first gas mixing cavity 13 and then is ejected from the combustion hole 22 on the top surface of the fire hood, the moving path from the air outlet 11 to the combustion hole 22 is prolonged, and the time for the second gas mixing is prolonged.

Further, the ejector body 1 is provided with a first air mixing cavity 13 and an ejector pipe 12, the first air mixing cavity 13 is communicated with the ejector pipe 12, an air inlet is formed in the ejector pipe 12, the air outlet 11 is located on the first air mixing cavity 13, so that the fuel gas is mixed for the first time in the ejector body 1, and when the fuel gas enters the ejector body 1 from the ejector pipe 12, the air around the air inlet is taken away and enters the first air mixing cavity 13 to be mixed for the first time.

Further, a plurality of first air ducts 31 are arranged on the outer side surface of the first air mixing cavity 13, the first air ducts 31 are arranged at intervals, and the first air ducts 31 form grooves.

Further, a second air passage 32 is arranged on the fire hood 2 at the position of the first air mixing cavity 13, the second air passages 32 are arranged at intervals, the first air passage 31 and the second air passage 32 form a plurality of air passages 3 communicated with the second air mixing cavity 21, the first air passage 31 and the second air passage 32 are arranged in a staggered mode, and the second air passage 32 forms a convex rib.

Further, the second air passage 32 is located at the air inlet end of the fire hood 2, mounting grooves 23 are formed in two sides of the air inlet end 24, and a connecting piece 14 matched with the mounting grooves 23 is arranged on the injection body 1.

The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
