Abstract

The utility model discloses an energy saver for a gas stove, belonging to the range of kitchen utensils. In the utility model, the high-low position of a pot supporter can be adjusted by the relative motion of pot support feet and an end cam or a thread part, flame can fully contact the bottom of the pot no matter whether strong fire or slow fire at the time of the combustion of a stove head, and the heat efficiency is improved thereby; so the purpose of energy saving is reached.

Description

Energy saver for gas stove

The utility model is gas furnace energy saver-genus kitchen utensils category.

Existing gas furnace, flame size can be regulated, and its burner (being commonly referred to as burner) to the distance between cooker bottom surface (as the bottom of a pan) designs by the big flame situation.When big flame, flame fully contacts with the cooker bottom surface, and the thermal efficiency is higher; And when using flammule, because of flame shortens, draw back with the distance of cooker bottom surface, the heat of burning is not fully utilized, and the thermal efficiency is lower.

The purpose of this utility model will overcome above-mentioned weak point exactly, design a kind of burner top and support the adjustable mechanism of high and low position of cooker, utilize the high and low position of regulating support component at any time, regulate the distance of burner and cooker bottom surface, flame is fully contacted with the cooker bottom surface, reduce heat loss, reach energy-conservation purpose.

The purpose of this utility model reaches by following measure:

Adopt pot support high and low position adjustable mechanism, promptly adopt cam lifting mechanism or the screw thread elevating mechanism that to regulate pot support high and low position.By the relative motion of pot support and cam part or screwed part, make the pot support rise or descend.

The purpose of this utility model also can reach by following measure:

1, used cam mechanism is a fixing edge cam, or make the furnace shell mouth of edge cam shape, the feet below the pot support contact with the helicoid of edge cam or the helicoid of furnace shell mouth, rotates pot to support, the pot spike slides along each helicoid, and pot supports rotation and lifting thereupon.

2, the feet below the pot support passes the fixing pilot hole that the support of restriction pot is rotated, and has a rotary band to stir the edge cam of handgrip below the pot spike, and a pot spike contacts with the cam helicoid.Stir handgrip cam is rotated, the pot support is risen or is descended under the synergy of cam helicoid and pilot hole, to regulate the distance up and down between pot support and burner.

3, used pot supports in the elevating mechanism, and the bottom of pot support is threaded, and this screw thread screws with the screw thread that is fixed on the screwed part at furnace shell mouth place, rotates a pot support, because the interaction of screw thread makes a pot support rotation and lifting.

4, used pot supports elevating mechanism, its pot spike passes the fixing pilot hole that the support of restriction pot is rotated, its pin is placed on the upper surface of rotating screwed part, the latter screws with the retaining thread parts that are fixed on the fire door place, rotate rotating screwed part, pot supports and raises under the acting in conjunction of the upper surface of rotating spiral lamination parts and pilot hole or reduction.

Accompanying drawing has been drawn the structure of the several embodiment of the utility model, wherein:

Fig. 1, Fig. 2 are the cam mechanism schematic diagram of pot support rotation and lifting;

Fig. 3, Fig. 4 are for the pot support is risen, the cam mechanism schematic diagram of decline (not rotating);

Fig. 5 is the thread mechanism schematic diagram of pot support rotation and lifting;

Fig. 6 is pot support ascending, descending (not rotating) thread mechanism schematic diagram;

Fig. 7 is to adopt pot support lifting (the not rotating) schematic diagram of cam and two kinds of mechanisms of screw thread simultaneously.

Description of drawings is as follows: (1) is furnace shell; (2) be handgrip; (3) be the pot support; (4) be screw; (5) be edge cam; (6) be cam chair; (7) be female threaded part; (8) be male thread part; (9) for connecing the thing dish; (10) be guide plate; ［ 11 ］ be the screwed part of band edge face cam; ［ 12 ］ be pilot hole; ［ 13 ］ be the pot spike; ［ 14 ］ be the furnace shell mouth of edge cam shape; ［ 15 ］ be the threaded pot support in bottom.

Below in conjunction with accompanying drawing embodiment is described further:

Among Fig. 1, Fig. 2, the pot spike is placed on the helicoid of edge cam, stirs handgrip the pot support is rotated, and the slip of its pin on the cam helicoid makes the change of pot support upper-lower position, the lifting while rotating.

Cam shown in Figure 3 places on the cam chair, the end sides of furnace shell has the slotted hole groove of a fore-and-aft direction, handgrip passes and wherein is fixed on the cam, stir handgrip, cam is free to rotate, and the pilot hole that the pot spike passes furnace shell drops on the helicoid of cam, rotating cam, the oscilaltion campaign is done in the pot support, and this mechanism not only is applicable to garden shape furnace shell mouth, also can be used for the block furnace faucal simultaneously.

Fig. 4 and Fig. 3 are slightly different.Be that cam is placed on above the furnace shell, guide plate be fixed on the furnace shell mouth that handgrip is on furnace shell with screw.

The helicoid of above-mentioned cam can be the curved surface of constant lift angle or band platform or band shallow slot.

Screw thread among Fig. 5 below the pot support is a pin thread, the screwed part band negative thread of furnace shell mouth.Stir the handgrip that is fixed in the pot support, then male thread part drives pot and supports the lifting while rotating together; Also male thread part can be fixed, female threaded part drives the pot support and makes rotary lifting movement.

Male thread part is fixed on the furnace shell mouth among Fig. 6, and the pot support is placed on the female threaded part by pilot hole, and female threaded part and male thread part screw, and when stirring the handgrip that is fixed on the female threaded part, then female threaded part drives pot support lifting when rotation and lifting.Female threaded part and handgrip can be below furnace shells (this form also is applicable to the block furnace faucal), also can be on the furnace shell mouth.In this structure, also female threaded part can be fixed, allow male thread part rotate, and drive pot support lifting; The face that rotatable screwed part supports the pot spike can be flat, also can make the edge cam shape.Make the screw thread of screwed part of edge cam shape and the helicoid of upper surface cam face on Fig. 6, rotation direction is opposite, and the combined mechanism of this cam and screw thread can increase the stroke up and down of pot support, or reduces the handgrip corner.

Screw thread in the utility model can be used various thread forms, and the helicoid lift angle must be less than the static friction angle of use material, to realize self-locking in the thread helix lift angle of thread mechanism and the cam mechanism.

The utility model, compared with prior art, have the following advantages: owing to adopted pot support high and low position adjustable mechanism, the distance that has realized burner and cooker bottom surface is adjustable, when making the cooker bottom surface no matter burn strong fire or weak fire, can both guarantee fully to contact with flame, thereby reduce heat loss, improve the thermal efficiency, reached energy-conservation purpose.
