Embodiment 1

[0057] Please refer to figure 1 , a high-efficiency gas cooker with a heat recovery function, including a combustion zone, an enclosed heat exchange area, and a pot placement area for placing cooking pots 50. In this embodiment, between the combustion area and the enclosed heat exchange area They are connected by an inner cavity partition 12, and the present invention does not limit the material of the inner cavity partition. The enclosed heat exchange area is located outside the combustion area, and the pot storage area is set above the combustion area and the enclosed heat exchange area. In order to improve the heat utilization rate of the high-temperature flue gas, the high-temperature flue gas is exchanged with the bottom of the cooking pot to reduce the temperature. The resulting medium-temperature flue gas exchanges heat with the combustion-supporting cold air, and passes the hot air formed by heating the cold air to the stove 10. The specific structure is as follows:

Embodiment 2

[0077] Please refer to Figure 9 and Figure 10 , a high-efficiency gas cooker with a heat recovery function, including a combustion area, an enclosure area and a pan area for placing cooking pots, the enclosure area is located outside the combustion area, and the pan area is set between the combustion area and the enclosure Above the area, in order to improve the heat utilization rate of the high-temperature flue gas, the medium-temperature flue gas obtained by exchanging the high-temperature flue gas with the bottom of the cooking pot and cooling down the temperature is exchanged with cold water, and the cold water is heated to form sanitary hot water for people to use . In order to further improve the heat utilization rate of the high-temperature flue gas, the present invention also utilizes the low-temperature flue gas (flue gas tail gas) discharged from the cooker, and conducts heat exchange with tap water through a tube-fin heat exchanger, and converts the cold tap wate...

Abstract

The invention relates to an efficient gas cooking appliance with a backheating function. The efficient gas cooking appliance comprises a combustion area, an envelope heat exchange area and a pot placing area. A cooking pot is placed in the pot placing area, the envelop heat exchange area is positioned on the outer side of the combustion area, and the pot placing area is arranged above the combustion area and the envelop heat exchange area. The envelop heat exchange area comprises a radiation cross-flow heat exchanger, a heat exchanger with double fluid channels and a high-position smoke outlet, and high-temperature smoke of a cooking range is guided by the radiation cross-flow heat exchanger, the heat exchanger with the double fluid channels and the high-position smoke outlet jointly so as to flow close to the bottom of the cooking pot. Accordingly, a forced flowing channel of the high-temperature smoke is formed, heat exchange between the high-temperature smoke and the bottom of the cooking pot is promoted, heat exchange is realized between medium-temperature smoke which is cooled after heat exchange of the bottom of the cooking pot and low-temperature combustion-supporting air which is supplemented into the cooking range, a backheating mechanism of the smoke is formed, high-temperature radiation of the high-temperature smoke to an environment and diffusion of the smoke in the environment are reduced, the temperature of the combustion-supporting air is increased, the temperature of the high-temperature smoke of the cooking range is also increased, and technical problems of low heat efficiency and severe environmental pollution of an existing gas cooking appliance are solved.

Description

technical field [0001] The invention relates to kitchen equipment, in particular to a high-efficiency gas cooker with a heat recovery function. Background technique [0002] The progress of artificial fire is the first time that human beings have consciously and successfully used natural forces to fundamentally improve the living conditions and development conditions of human beings. Engels said, "As far as world liberation is concerned, the progress of artificial fire has surpassed that of steam engines." The advancement of artificial fire and the rise of cooking activities using fire as a heat source have created a wonderful food culture for mankind and "China on the tip of the tongue". [0003] Food culture is becoming more and more complex and mysterious, but for thousands of years, cooking stoves, from the bell tripods of the Han and Tang Dynasties to today's gas stoves, have not undergone subversive changes in their basic functions and main structures: Fuels such as ...
