Waste heat collecting cover of cooking range

Abstract

The invention discloses a waste heat collecting cover of a cooking range. The waste heat collecting cover comprises a collecting cover body, an isolation layer and a heat exchange water pipe; the top and the bottom of the collecting cover body are each provided with an opening, and the opening in the top of the collecting cover body is sealed through a heating body; the opening in the bottom of the collecting cover body, and the collecting cover body is placed on the cooking range; the isolation layer is arranged in the collecting cover body to separate space in the collection cover body into a heating area and a waste heat collecting area, and a fire spraying opening of the cooking range is placed in the heating area; the top of the heating area and the top of the waste heat collecting area are communicated, and waste heat for the heating area enters the waste heat collecting area from the top of the heating area; the heat exchange water pipe is arranged in the waste heat collecting area; and the heat exchange water pipe is arranged around the isolation layer, one end of the heat exchange water pipe stretches out of the collecting cover body to be communicated with a water source, and a discharging opening controlled by a valve is formed in the position, arranged on the collecting cover body, of the other end of the heat exchange water pipe.

Description

technical field [0001] The invention relates to waste heat utilization equipment, in particular to a stove waste heat collection cover. Background technique [0002] Currently used stoves, the junction of the heating area and the heating surface are generally open, the heat absorbed by the heating body or the heating surface is only about 20% of the heat generated by the fuel, and the remaining 80% of the heat is dissipated in the kitchen air through the opening. As a result, the temperature in the kitchen is high, the heat utilization rate is low, resources are wasted, and use is inconvenient. Secondly, although there are stoves that collect waste heat at present, because the device for collecting waste heat is integrated with the stove, the volume of the stove is large, limited by the small area of ​​ordinary family kitchens, it cannot be popularized, and it is inconvenient; It is integrated with the stove and cannot be separated, so that the stove in use without the wast...

AI Technical Summary

Problems solved by technology

[0002] Currently used stoves, the junction of the heating area and the heating surface are generally open, the heat absorbed by the heating body or the heating surface is only about 20% of the heat generated by the fuel, and the remaining 80% of the heat is dissipated in the kitchen air through the opening. It leads to high temperature in the kitchen, low heat utilization rate, waste of resources, and inconvenient use

Secondly, although there are stoves that collect waste heat at present, because the device for collecting waste heat is integrated with the stove, the volume of the stove is large, limited by the small area of ​​ordinary family kitchens, it cannot be popularized, and it is inconvenient; It is integrated with the stove and cannot be separated. As a result, the stove in use without waste heat collection device cannot collect waste heat and reuse it, which is inconvenient
