Cooking range discharge flue

Abstract

The utility model discloses a cooking range discharge flue which comprises a cooking range base, and a discharge flue combined cooking range structure is installed on the cooking range base. The exhaust flue combined stove structure comprises a stove head, a fire cover, a fuel gas inlet pipe, a stove shell, five combined stove bricks, a combustion heating cavity, an air duct pipe and a stove top cover, and the utility model relates to the technical field of stoves. Due to the fact that no discharge flue exists, along with the increase of combustion use time, gas combustion can generate waste gas such as carbon dioxide and nitric oxide, the waste gas cannot be discharged, natural gas cannot be completely combusted, and the heat supply efficiency is affected.

Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to a stove smoke exhaust duct. Background Art

[0002] A stove is a common kitchen appliance used for cooking and boiling food. It usually consists of a heating source and a structure that supports a cooking container. Existing stoves all use direct combustion to provide energy for cooking. When in use, due to the lack of a flue gas duct, as the burning time increases, gas combustion will produce waste gases such as carbon dioxide and nitrogen oxides. The inability to discharge waste gases will cause the natural gas to not be completely burned, affecting the heating efficiency. Summary of the invention

[0003] To achieve the above objectives, the utility model is implemented through the following technical solutions: a stove exhaust duct, comprising: a stove base, on which an exhaust duct combined stove structure is installed;

[0004] The exhaust flue combined stove structure includes: a stove head, a fire cover, a gas inlet pipe, a stove shell, five combined stove bricks, a combustion and heating cavity, an air duct pipe and a stove top cover;

[0005] The burner head is embedded in the middle position of the stove base, the fire cover is installed on the burner head, the gas inlet pipe is installed on the air inlet at the lower end of the stove base, the stove shell is installed on the stove base, five combined furnace bricks are spliced ​​and combined and installed on the inner wall of the stove shell, the combustion and heating cavity is located inside the stove shell, the air duct pipe penetrates the stove shell and the combined furnace bricks and extends into the combustion and heating cavity, and the stove top cover is installed on the stove shell.

[0006] Preferably, the stove base and the stove shell are connected by fixing bolts.

[0007] Preferably, an exhaust air duct is provided in the air duct pipe.

[0008] Preferably, a plurality of air inlet slots are provided on the stove top cover.

[0009] Preferably, a support block is installed on the stove top cover.

[0010] Preferably, the stove top cover is fixed to the stove housing by means of locking nuts.

[0011] Beneficial Effects

[0012] The utility model provides a stove exhaust duct, which has the following beneficial effects: this solution uses an exhaust flue combined with a stove structure, and an air intake slot is arranged on the stove to facilitate the entry of external air to provide sufficient oxygen for natural gas combustion. At the same time, an exhaust flue structure is added to facilitate the discharge of waste gas generated by combustion, ensuring sufficient combustion, and solving the problem that existing stoves all use direct combustion to supply energy for cooking. When in use, due to the lack of a flue, as the combustion time increases, the combustion of gas will produce waste gases such as carbon dioxide and nitrogen oxides. The inability to discharge the waste gas will cause the natural gas to be unable to burn completely, affecting the heating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0017] Example: See Figure 1-2 When using the exhaust flue combined stove structure, the stove base 1 is connected to the lower end of the stove shell 5 by using fixing bolts 10, and then the combined furnace bricks 6 are fitted and fixed on the inner wall of the stove shell 5, and the stove top cover 9 is fixed to the stove shell 5 by using locking nuts 14. When in use, the gas inlet pipe 4 is connected to the gas supply pipeline to provide natural gas. The natural gas is transported to the inside of the burner 2 and ignited, and then sprayed out from the opening of the fire cover 3 installed above to burn and provide heat. The exhaust gas generated by the combustion is discharged through the exhaust air duct 11 opened in the air duct pipe 8, so as to ensure the full combustion of the natural gas and the heating efficiency.

[0018] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
