Abstract
The utility model relates to an energy-saving pot (kettle), which can improve the efficiency of heat transfer by enlarging the heat transfer area and improve the effect of turbulent flow heat transfer. The utility model is characterized in that the heating surface of the bottom of the energy-saving pot (kettle) is provided with a plurality of protrusions, and the height of the protrusions protruded from the bottom surface of the pot (kettle) is several times or dozens of time as long as the thickness of the metal material of the bottom of the pot (kettle); the protrusions is radially arranged outwards in the intermittent and cross way by taking the geometric centre of the pot (kettle) bottom as the center of a circle. The utility model has the advantages of energy saving, time saving, and safety.
Description
The utility model relates to a kind of cooking utensils.
At present, the unit volume heat transfer area of cookers such as metal pan, kettle is little, and the main heating surface roughness that contacts with stove fire is little, the turbulent flow heat transfer composition is few, and heat transfer efficiency is low, simultaneously, the liquid that overflows in the cooker flow to the burner head of gas furnace easily by the outer bottom center, make fray-out of flame.
The purpose of this utility model is both to have increased heat transfer area by improving the shape of metal pan, kettle bottom, increases turbulent flow heat transfer again, make it to become a kind of energy-conservation, save time and can when liquid overflows, prevent or reduce the novel cooker that extinguishes gas furnace danger.
For achieving the above object, the technical solution of the utility model is to be distributed with several thrusts on pot, kettle bottom heating surface, the height that these thrusts protrude in pot, kettle bottom surface is pot, several times to tens times of kettle bottom metal material thickness, and these thrusts with pot, kettle at the bottom of geometric center be the center of circle, radially, intermittently, intersect and outwards to arrange.
Major advantage of the present utility model is to consider the effect that improves turbulent flow heat transfer when increasing metal pan, kettle bottom heat transfer area, have energy-conservation, save time, use the characteristics of safety, and this kind pot, kettle heated face structure are reasonable, manufacture easily.
Introduce an embodiment of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing 1 is the utility model embodiment bottom shape schematic diagram that is heated.
Accompanying drawing 2 is A-A profiles of accompanying drawing 1.
At this, provide a kind of distribute radially example of rectangle rib (2) of two circles that increases in little common pan, kettle bottom (1), concrete shape, rib distributes and sees accompanying drawing 1.Metal pan, kettle bottom (1) material thickness are 1 millimeter, and the height that rectangle rib (2) protrudes in pot, kettle base plane is 4 millimeters (seeing accompanying drawing 2).
When this pot, kettle place when heating on the stove fire, the rectangle rib repeatedly makes thermal current change direction on the one hand, to form turbulent flow, the rib of projection has also increased the heat transfer area of pot, kettle bottom and thermal source on the other hand, and both contribute to improving heat transfer efficiency.In addition, the flow direction bottom centre that the rib of projection can also stop pot, kettle to overflow can prevent or reduce the danger that the combustion gas stove fire is extinguished.
Claims (2)
1, a kind of energy-conservation pot, kettle, it is characterized in that: be distributed with several thrusts on pot, the kettle bottom heating surface, the height that these thrusts protrude in pot, kettle bottom surface is pot, several times to tens times of kettle bottom metal material thickness, and these thrusts with pot, kettle at the bottom of geometric center be the center of circle, radially, intermittently, intersect and outwards to arrange.
2, energy-conservation pot according to claim 1, kettle, it is characterized in that: thrust is rectangle rib or column.
