Abstract

The utility model discloses an upper air inlet combustion device, which comprises a combustor; the combustor comprises a central air inlet pipe and more than one main air inlet pipe; the top end of the central air inlet pipe is provided with a central nozzle; a main burner is arranged at the top end of the main air inlet pipe; below the burner, a nozzle assembly is arranged; the nozzle assembly is located above the cooktop panel; a heat insulating plate is disposed at the inlet of the central inlet duct and the main inlet duct to separate the central inlet port and the main inlet port below the heat insulating plate. Compared with the prior art, the nozzle assembly is in a fully open state due to the air inlet holes formed in the nozzle assembly; the heat insulation plate enables the nozzle and the oxygen supply air flow of the burner to be mutually isolated and not to be interfered, and the ignition is very easy when one comes. When the heat flow is increased and the gas supply is increased, the combustor and the nozzle assembly have enough oxygen intake, so that the gas is combusted fully, and the heat efficiency is greatly improved.

Description

An upward air-intake combustion device

technical field

The utility model relates to a gas cooker, in particular to an upward air intake combustion device.

Background technique

In the prior art, the combustion mode of the gas stove is divided into an inner flame and an outer flame, and the outer flame is divided into an upper air inlet and a lower air inlet. The existing outer flame upward air intake burner is to set the nozzle in an open nozzle assembly, and a burner seat is placed on it. When the gas of the nozzle is sprayed out, because the nozzle assembly is in a semi-closed state, it belongs to the sinking type. Upward air intake; when the heat flow increases and the gas supply increases, the amount of oxygen inhaled by the burner intake pipe is insufficient, the gas combustion is incomplete, and the combustion flame is not strong, which seriously affects the improvement of thermal efficiency;

Although there is isolation between the nozzle and the nozzle of the burner intake pipe, due to the small area, it cannot increase the oxygen intake, and the nozzle and the burner oxygen supply flow intersect and interfere with each other; for this reason, this application People have applied for a patent in addition, and there are ventilation holes on the vertical wall of the nozzle assembly, which effectively solves this problem.

However, a new problem was discovered during the application, that is, the nozzle of the burner competed with the vent hole on the vertical wall of the nozzle assembly for oxygen, that is, the space close to the stove, most of the airflow flowed to the nozzle, and the airflow into the vent hole was insufficient.

There must be a device separating the two.

People are eager to solve this problem, make the burning flame more vigorous, and improve the thermal efficiency of the burner.

Utility model content

The purpose of the utility model is to provide an upward air-intake combustion device aiming at the deficiencies of the prior art.

The utility model is realized by adopting the following technical solutions.

Design and manufacture an upward air-intake combustion device, including:

A burner; the burner includes a central air intake pipe and more than one main air intake pipe; a central burner is arranged on the top of the central air intake pipe;

A main burner is arranged on the top of the main air intake pipe;

Below the burner, a nozzle assembly is arranged; the nozzle assembly is located on the cooker panel;

A heat shield is arranged at the entrance of the central air intake pipe and the main air intake pipe, separating the central air inlet and the main air inlet under the heat shield.

An air inlet hole is opened on the wall of the inner chamber of the nozzle assembly.

Compared with the prior art, the utility model is provided with a heat shield at the lower part of the burner, and an air inlet hole is added on the nozzle assembly, so that the nozzle assembly is in a fully open state; the heat shield makes the nozzle and the burner supply oxygen The air flow is isolated from each other without interfering with each other, and the ignition is very easy.

When the heat flow increases and the gas supply increases, the burner and the nozzle assembly have enough inhaled oxygen to make the gas burn fully, the thermal efficiency is greatly improved, and there will be no fire extinguishing phenomenon.

Description of drawings

The utility model is further described below using the drawings, but the embodiments in the drawings do not constitute any limitation to the utility model.

Fig. 1 is the schematic diagram of a kind of outer flame type upward air intake combustion device in the prior art;

Fig. 2 is a schematic diagram of an upward air-intake combustion device with a heat shield added in the present invention.

detailed description

The utility model will be described below in conjunction with specific embodiments.

As shown in Figure 2, a kind of upward wind combustion device is designed and manufactured, including:

A burner 1; the burner 1 includes a central air intake pipe 12 and more than one main air intake pipe 11; the top of the central air intake pipe 12 is provided with a central burner 123;

A main burner 113 is arranged at the top of the main intake pipe 11;

Below the burner 1, a nozzle assembly 3 is arranged; the nozzle assembly 3 is located on the cooker panel 4;

A heat shield 2 is arranged at the entrances of the central air intake pipe 12 and the main air intake pipe 11 , separating the central air inlet 121 and the main air inlet 111 under the heat shield 2 .

An air inlet hole 5 is opened on the inner wall 35 of the nozzle assembly 3 .

In the utility model, a heat insulation board is arranged at the lower part of the burner, and an air inlet hole is added on the nozzle assembly 3, so that the nozzle assembly 3 is in a fully open state; Ignition is very easy without interference.

When the heat flow increases and the gas supply increases, the burner and the nozzle assembly have enough inhaled oxygen to make the gas burn fully, the thermal efficiency is greatly improved, and there will be no fire extinguishing phenomenon.

The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation and scope of application. The content of this specification should not be understood as Limitations on the Invention.
