Large cooking range for cooking

Abstract

The invention belongs to the technical field of waste heat utilization of cooking ranges, and particularly relates to a large cooking range for cooking. The large cooking range comprises a rack and a hearth; the hearth comprises a hearth wall and a hearth bottom; and the hearth is sleeved with a layer of outer shell matched with the hearth in shape, and a heat preservation space capable of containing heat preservation materials is formed between the outer shell and the hearth. The large cooking range for cooking further comprises a heat reflection disc, the heat reflection disc comprises a conical plate which is in the shape of a horn mouth, the upper caliber of the conical plate is larger than the lower caliber of the conical plate, the small-caliber end of the conical plate forms a matching end for the furnace end to extend into, and the large-caliber end of the conical plate is lapped on the inner wall of the hearth wall from top to bottom, so that the hearth is divided into an upper cavity and a lower cavity. A smoke inlet is formed in the disc face of the conical plate in a penetrating mode, and a smoke exhaust pipe communicating with the smoke inlet sequentially penetrates through the hearth and the outer shell. The combustion heat efficiency of the cooking range can be effectively improved, the actual service life of the hearth is greatly prolonged, and the cooking range has the characteristics of being energy-saving, long in service life and easy to repair and maintain.

Description

Technical field [0001] The present invention belongs to the field of stove, and it is specifically related to a large pot of cooker. Background technique [0002] There are a large number of large pot stoves in the Chinese market, and are widely used in the canteen of the organs and schools and schools. At present, there are many traditional single-layer furnace structures, and this type of furnace is made of refractory bricks; this refractory brick furnace is low, but there is easy to fry, heat reflection. Poor feature, high maintenance and maintenance rate, and the shortcomings of the waste heat utilization and even without heat utilization, need to be resolved. Inventive content [0003] It is an object of the present invention to overcome the deficiencies of the prior art, providing a large pot of cooker, which can effectively improve the combustion efficiency of the stovetop, and greatly extend the actual life of the furnace, and synchronize with energy saving, long life an...

AI Technical Summary

Problems solved by technology

At present, most of the large cooking pots and stoves in the market adopt the traditional single-layer furnace structure, and such furnaces are mostly made of refractory bricks; The shortcomings of poor characteristics, high maintenance rate and low or no waste heat utilization need to be solved urgently
