Description

A kind of adjustable hot pot stove

The utility model relates to a kind of adjustable hot pot stove.

Existing adjustable hot pot stove described in Chinese patent CN2048166u, has some equally distributed grooves crack on its adjuster, the pulling adjusting rod, when flame jet was parallel with groove crack mouth, flare was dispersion shape, when flame jet was vertical with groove, flame was concentrated, and reduced power consumption.The shortcoming of this adjuster is flame can not be transferred to extinguish, and the amplitude of adjusting is very limited, and regulates with the mode of pulling adjusting rod, relatively effort.

The purpose of this utility model is to provide a kind of new-type stove, but regulated at will flame amount is very laborsaving in the time of making full use of heat energy and adjusting.

In order to achieve the above object, the driving mechanism by end basin, flue, adjuster, burner and adjuster of the present utility model is formed.Adjuster has a fixed disk, opens an annular groove above, and rolling disc is just put into this groove, and can rotate in groove; One end of page or leaf sheet is fixed on the fixed disk, and the page or leaf sheet can rotate by this fixing point on fixed disk.Open a microscler sulculus on the stiff end of page or leaf sheet, the projection on the rolling disc is can be in this groove movable, and the direction of sulculus and page or leaf sheet be the 90 °＜θ of angle of line≤180 ° end to end; The quantity of page or leaf sheet is more than two.Rotate toggle mechanism, turn disc, it is to rotate inside and outside the center of circle with the fixing point that the projection on the rolling disc just drives the page or leaf sheet.When the page or leaf sheet outwards rotated simultaneously, the area of bocca increased, and the intensity of a fire also increases thereupon; When oppositely changeing, bocca draws in until closure, and the intensity of a fire also is decreased to gradually to be extinguished.

Therefore, use is originally novel can control the intensity of a fire freely, because bocca is positioned at flame kernel all the time, capacity usage ratio is the highest, greatly reduces power consumption; Driving mechanism is made up of gear and knob simultaneously, and is because the diameter of knob is far longer than the diameter of gear, very laborsaving during rotation.And the utility model is simple and light, and cost is low, is very suitable for family and restaurant.

Describe preferred forms of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is a partial sectional view of the present utility model;

Fig. 2 is the adjuster vertical view;

Fig. 3 is a page sheet schematic diagram.

In Fig. 1, we can see: putting a fixed disk 17 on the flue, opening an annular groove 9 in this dish, rolling disc 10 can just be put into 9 li of grooves, and can freely rotate in groove.On the top average mark face of rolling disc 10 several projections 11, the quantity of projection 11 is the same with the quantity of page or leaf sheet 13, is more than 2, is preferably 3-6; When the height of projection 11 will make burner (1) be placed on the fixed disk 17 of adjuster (2), both outers can coincide, so that with screw burner 1, adjuster 2 and chassis 3 are fixed.

In Fig. 2 and Fig. 3, page or leaf sheet 13 be shaped as waist shape, head be semicircle, the semicircle center is fixing loosely with screw, on fixed disk 17, page or leaf sheet 13 can be around 12 rotations of the fixing point on the fixed disk 17.Have microscler sulculus 14 on the stiff end of page or leaf sheet 13, the width outline of sulculus 14 is wider than the diameter of projection 11, make projection 11 can be in sulculus 14 movable, the direction of sulculus 14 is to be that the center is to extraradial direction with fixing point 12, a line is drawn at the center end to end that connects page or leaf sheet 13, sulculus 14 is θ with the angle of this line, so 90 °＜θ≤180 °.When the sulculus 14 of page or leaf sheet 13 was enclosed within on the projection 11 of rolling disc 10, rolling disc 10 rotated, and it be center of circle rotation with fixing point 12 that projection 11 has just driven whole page or leaf sheet 13.

In Fig. 2, the quantity of page or leaf sheet is 4, and the afterbody of each sheet all rides over the first half of adjacent a slice, is barricaded as annular.When the page or leaf sheet inwardly rotates simultaneously, will cover on the bocca, reduce the area of bocca, reduce the intensity of a fire; And, then increase the area of bocca when the outwards rotation simultaneously of page or leaf sheet, increase the intensity of a fire.Because each sheet page or leaf sheet all is subjected to the pressure of adjacent a slice afterbody, and also be subjected to the holding power of adjacent another sheet head simultaneously, therefore stressed even, unlikely owing to the stressed irregular motion-impeding phenomenon that produces.

As a kind of embodiment of the present utility model, the main member of the driving mechanism 8 on the adjuster 2 is gear 5 and knob 7.As depicted in figs. 1 and 2, gear 5 is connected with the connecting rod 6 that passes burner 1, and the other end of connecting rod 6 is a knob 7.The radius of knob 7 is far longer than the radius of gear 5, forms a laborsaving lever.Have the tooth mouth 15 of several rows of camber on the rolling disc 10, gear 5 just snaps in the tooth mouth 15, and turning knob 7 just drives rolling disc 10 by gear 5 and rotates.Because the angle that page or leaf sheet 13 rotates is generally all smaller, so the total length of tooth mouth 15 gets final product in 30mm～40mm.In order to allow gear 5 snap in better in the tooth mouth 15,9 parts of the groove under the tooth mouth 15 can be hollowed out, the length of cut-out must between 45mm～60mm, make gear 5 can not be subjected to the obstruction of groove 9 in rotation process greater than the total length of tooth mouth 15.

For hot pot stove is dispelled the heat better, can each makes a call to a circle louvre (not marking among the figure) on the Lower Half of burner and chassis 4.

Page or leaf of the present utility model sheet 13 also can be other shape, and rectangle for example, or have only on one side for arc etc. is rotated and regulated the intensity of a fire so long as utilize rolling disc to drive a page or leaf sheet, all falls in the protection domain of the present utility model.
