Embodiment Construction
[0030] like figure 1 And a feasible embodiment of the present invention shown in Fig. 2, it has a body of heater 3, divides into two parts with body of heater dividing plate 5 in the body of heater 3, the bottom is a combustion chamber, the top is a furnace, and a furnace is built-in Cooking pot 1, there is a medium gap between the furnace and the cooking pot 1 and it is filled with heat storage medium 25, the top of the furnace is sealed with a furnace cover plate 8, and the furnace body 3 corresponding to the combustion chamber is provided with a burner port 16 .
[0031] A furnace shell 4 is also provided outside the furnace body 3, and there is a convection gap between the furnace shell 4 and the periphery of the furnace body 3. The furnace body 3 is an overhead design in the furnace shell 4. There is a convection gap between the bottom plates 13 of the shell 4, and the furnace bottom plate is used to support the channel steel 14 between them. The tube sheet 6 is capped....

The invention relates to a cooking furnace, and proposes a solid phase change heat storage cooking furnace, which has a furnace body, a combustion chamber below the furnace body, and a furnace lining above the furnace. A cooking pot is built in the furnace lining. There are medium gaps between them and several convection pipes and solid heat storage medium are provided. The furnace body is provided with a furnace shell. There is a convection gap between the furnace shell and the furnace body, and the convection gap communicates with the chimney. Compared with the prior art, the present invention has the following substantive features and significant progress: 1. Double furnace body design with furnace shell, good thermal insulation performance. 2. The flue gas flows in the convection pipe and the convection gap for a long time, and the flue gas transfers more heat to the heat storage medium. 3. The solid heat storage medium has a phase change heat storage, which has a greater heat storage capacity. After the burner stops burning, the cooking state continues to be kept for a longer time in the cooking pot. 4. The solid heat storage medium uses a mixture of several salts, and the melting point temperature can be adjusted according to the design requirements to achieve the best use effect. 5. High thermal efficiency and energy saving.
Description
technical field [0001] The present invention relates to cooking furnaces, in particular to cooking furnaces with heat storage capability. Background technique [0002] In the prior art, cooking furnaces can be divided into two types, one is a direct heating type, and the other is an indirect heating type. [0003] The direct heating cooking furnace directly heats the water container, and transfers the heat from the heat source to the water directly through the heating surface. The disadvantages of this cooking furnace are: [0004] 1. The part where the heating surface is close to the heat source has high temperature and is easy to form a thick scale layer. The heat transfer capacity of the scale layer is very poor, which hinders heat transfer. It is easy to burn the food, and the service life of the furnace body is short. [0005] 2. There is no heat storage function. After the furnace is turned off, the water temperature drops quickly, and it takes a long time to raise t...
