Cooker racks
Technical field
The present invention relates to a kind of cooker racks of gas-cooker.
Background technology
The height of cooker racks is fixed, but the shape in the bottom of a pan is fixing, have to lower convexity, nearer apart from duration and degree of heating, have plenty of concave bottom flat or that make progress, far away apart from duration and degree of heating.Textbook is divided into flame envelope, internal flame, flame core with the flame of alcolhol burner, the flame envelope temperature is the highest, this is controversial, and gas-cooker is different with alcolhol burner, alcolhol burner burning required air obtains from the outside of flame, and gas-cooker burning required air enters from the kitchen range below, and combustion gas mixing, sufficient combustion.Facts have proved, the bottom of a pan is nearer apart from duration and degree of heating, and firing rate is faster, and is more energy-conservation, and the bottom of a pan is far away apart from duration and degree of heating, then opposite.For addressing this problem, designed can lifting cooker racks, but need manual adjustment, use inconvenience, be difficult to the effect that reaches energy-conservation.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of cooker racks, and is easy to use, energy savings.
Above-mentioned technical problem is to solve like this: this cooker racks comprises upper frame, guide pillar and spring, and upper frame comprises guide pin bushing and collar, and the guide pin bushing upper end connects collar, and spring is positioned at guide pin bushing, and guide pillar is corresponding one by one with guide pin bushing, and guide pillar is positioned at guide pin bushing and is positioned under the spring.
The guide pin bushing of upper frame is enclosed within outside the guide pillar, and spring is positioned on guide pin bushing and the guide pillar, and the guide pillar lower end is placed on the kitchen range top.Pot is pushed down upper frame, the guide pin bushing pressing spring, and upper frame descends, and no matter what shape the bottom of a pan is, and the bottom of a pan all is located immediately on the kitchen range, is in apart from the nearest position of duration and degree of heating, need not manual adjustment.Fire hole on the kitchen range is positioned at the side mostly, and the bottom of a pan can not pushed down fire hole.Fire hole such as kitchen range makes progress, and can place a thrust at kitchen range and block the bottom of a pan, makes the bottom of a pan not push down fire hole and gets final product.During use, downward when the isostasy that upper frame is subject to, upper frame descends.When the upper frame discontinuity equalization, center of gravity is when the upper frame side, and guide pillar and guide pin bushing just are not positioned at same center line, and both sprain mutually, and guide pillars and bushes can not relative motion.Therefore, upper frame is always with the level vertical lift, can not place improperly to tilt because of pot, and is fool proof.
As preferably, the quantity of guide pillar, guide pin bushing and spring is four, and pot and cooker racks are all placed steadily.
As improvement, divide into the bottom set circle at guide pillar, the guide pillar lower end connects the foundation ring, and the foundation ring is placed on the kitchen range top.Guide pillar connects the foundation ring, matches with upper frame with guide pin bushing.Spring is put into guide pin bushing, will guide pillar the upper end insert guide pin bushing, cooker racks just become one can change in elevation integral body.
Technique scheme and improvement thereof utilize the weight of pot self to be pressed on the upper frame, and upper frame descends, and the bottom of a pan is located immediately on the kitchen range, and is nearest apart from duration and degree of heating, easy to use, safe and reliable, saves the energy, need not manual adjustment, be applicable to the difform the bottom of a pan.
Description of drawings
Be described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram of cooker racks.
The specific embodiment
As shown in Figure 1, cooker racks comprises upper frame 1, guide pillar 2 and spring 3, and upper frame 1 comprises guide pin bushing 4 and collar 5, and guide pin bushing 4 upper ends connect collar 5, and spring 3 is positioned at guide pin bushing 4, and guide pillar 2 is corresponding one by one with guide pin bushing 4, and guide pillar is positioned at guide pin bushing 4 and is positioned at spring 3 times.
The guide pin bushing 4 of upper frame 1 is enclosed within outside the guide pillar 2, and spring 3 is positioned on guide pin bushing 4 and the guide pillar 2, and guide pillar 2 lower ends are placed on the kitchen range top.Pot is pushed down upper frame 1, guide pin bushing 4 pressing springs 3, and upper frame 1 descends, and no matter what shape the bottom of a pan is, and the bottom of a pan all is located immediately on the kitchen range, is in apart from the nearest position of duration and degree of heating, need not manual adjustment.Cooker racks and kitchen range bear the weight of pot jointly.Pot is taken away, and spring 3 pushes back original height with upper frame 1.
The quantity of guide pillar 2, guide pin bushing 4 and spring 3 is four.
Divide into bottom set circle 6 at guide pillar 2, guide pillar 2 lower ends connect foundation ring 6, and foundation ring 6 is placed on the kitchen range top.Guide pillar 2 connects foundation rings 6 and forms wholely, matches with upper frame 1 with guide pin bushing 4.Spring 3 is put into guide pin bushing 4, guide pin bushing 4 is inserted in guide pillar 2 upper ends, cooker racks just become one can change in elevation integral body.
