Abstract

The utility model provides an ideal domestic coal stove for the technical field of a domestic stove range, which is mainly characterized in that the upper part of a stove cover is provided with an air chamber, the air inlet tube of an air chamber is installed between the stove core and a stove casing barrel, and the air inlet tube is communicated with a stove door. Thus, the air which enters into the air chamber through the air inlet tube of the air chamber from the stove door rotates around the outer wall of the stove core to form hot air and to expand to enlarge pressure and flow rate, and thereby, the hot air which flows into the upper part of a stove chamber from the air chamber can support combustion at a stove port. Compared with the exiting domestic coal stove, the utility model has the obvious advantages that the utility model can make the coal have sufficient combustion, the temperature at the stove port can be improved, the heat utilization factor can be improved, etc.

Description

Domestic coal stove

The utility model belongs to the home furnace technical field, is a kind of commercial coal stove.

Existing coal stove, its body of heater have combustion chamber and furnace shell tube, and combustion chamber is sleeved in the furnace shell tube, between be provided with secondary wind inleting tube, furnace shell tube bottom is provided with a blast pipe (firedoor hole).Enter the wind of combustion chamber bottom and the wind in secondary wind inleting tube enters combustion chamber helps coal combustion through a blast pipe (firedoor hole).Because the cold wind that combustion chamber upper end oral area enters can reduce the fire door temperature, the coal combustion that therefore exists combustion chamber top is insufficient, and combustion chamber upper end oral area temperature is low, the deficiency that heat utilization efficiency is lower.

To be that design is a kind of can charge into the high hot blast of flow velocity at combustion chamber upper end oral area to the purpose of this utility model, can make the coal combustion on combustion chamber top more abundant, can improve the fire door temperature, thereby improve the commercial coal stove of heat utilization efficiency.

The main technical schemes that the utility model is taked is improved existing commercial coal stove, on combustion chamber top one air chamber is set, be provided with ventilating opening between combustion chamber upper end and the air chamber, and between combustion chamber and furnace shell tube, be provided with the air chamber blast pipe, air chamber blast pipe one end communicates with air chamber, and the other end communicates with firedoor hole.

This commercial coal stove of the utility model, owing to be provided with an air chamber on its combustion chamber top, can the wind of air chamber will be entered from firedoor hole through the air chamber blast pipe, in air chamber, rotate the formation hot blast around furnace core outer wall, and the increase pressure that expands, strengthen flow velocity, can help coal combustion in fire door portion, make coal combustion more abundant thereby air chamber charges into the hot blast on combustion chamber top.Compare with existing commercial coal stove, have and to make coal combustion more abundant, can improve the fire door temperature, can improve remarkable advantages such as heat utilization efficiency.

Reach the specific structural features that example further specifies the utility model commercial coal stove in conjunction with the accompanying drawings.

Accompanying drawing is represented the structure cutaway view of the utility model commercial coal stove.

Referring to accompanying drawing, the utility model commercial coal stove comprises: combustion chamber 3, furnace shell tube 1, air chamber 5, air chamber blast pipe 4.Combustion chamber 3 is filled with thermal insulation layer 6 between being sleeved in the furnace shell tube 1, air chamber 5 is sleeved on combustion chamber 3 tops week edge, the combustion chamber upper end is provided with the ventilating opening that communicates with air chamber 5, air chamber blast pipe 4 is contained between combustion chamber 3 and the furnace shell tube, one end communicates with air chamber 5, the other end communicates with firedoor hole 2, between combustion chamber 3 and the furnace shell tube 1 secondary wind inleting tube 7 is housed also.

Claims

1, a kind of commercial coal stove, have combustion chamber, furnace shell tube, fire door, secondary wind inleting tube, it is characterized in that also having air chamber, the air chamber blast pipe, air chamber is sleeved on combustion chamber top week edge, the combustion chamber upper end is provided with the ventilating opening that communicates with air chamber, the air chamber blast pipe is contained between combustion chamber and the furnace shell tube, and air chamber blast pipe one end communicates with air chamber, and the other end communicates with firedoor hole.
