Description

Automatic distance adjustment double burner gas stove

technical field

The utility model relates to a gas cooker, in particular to a double burner gas cooker.

Background technique

Existing gas cooker is made up of fire cover, burner head that is connected as a whole with gas pipe, fire power regulating valve, ignition device, kitchen range body, pot support. The disadvantage is that the relative position of the burner head and the pot body is always fixed, and the increase or decrease of the flame height caused by the increase or decrease of the gas consumption is not considered. When the gas volume is increased, that is, the fire is turned up, the flame increases, and a large number of flames slide from the bottom of the pot to the upper part of the pot, and the heat loss is large; when the gas volume is reduced, that is, the fire is turned down, the flame is low, and only the residual heat of the flame is used to heat the pot body. The above-mentioned situation leads to the low thermal efficiency and large energy consumption of the existing gas stove.

The transmission mechanism includes a crank and a connecting rod, the crank is fixed on the rotating shaft, the connecting rod is movably connected to the crank, and the other end of the connecting rod is movably connected with the lifting member. Alternatively, the transmission mechanism includes a gear and a rack, the rotating shaft is fixed with a gear, the gear is in transmission connection with the rack, and the rack is fixed on the lifting member or integrated with the lifting member.

The lifting member is a cylinder, and the guide member is a guide cylinder. Or the lifter is a column, and the guide is a guide sleeve.

The air intake pipe is a hose.

Detailed ways

Below in conjunction with the embodiment that accompanying drawing provides, the structure of the present utility model is described further.

As shown in Figures 1, 2, and 4, an automatic distance-adjustable double-burner gas stove includes a stove body 1, a switch 2, a burner 3, an air intake pipe 4, and a fire control valve 5. The fire control valve 5 and the burner 3 Connect with the intake pipe 4 between them, the shaft 2-1 of the switch 2 is fixed with a driving gear 6, the driving gear 6 meshes with the first driven gear 7 on the shaft 5-1 of the fire regulating valve 5; the driving gear 6 also It meshes with the second driven gear 8, and the second driven gear 8 is fixedly connected to the rotating shaft 9; the rotating shaft 9 is connected to the lifting member 12 through a transmission mechanism; the burner 3 is fixed on the lifting member 12 or made with the lifting member 12 Integral; the lifting member 12 is slidably matched with the guide member 15 installed on the stove body 1 .

As shown in FIG. 5 , the transmission mechanism includes a crank 10 and a connecting rod 11 . The crank 10 is fixed on the rotating shaft 9 , and the connecting rod 11 is movably connected to the crank 10 .

As shown in Fig. 6, another kind of transmission mechanism that the utility model can adopt comprises gear 18 and rack 19, and gear 18 is fixed on rotating shaft 9, and gear 18 is connected with rack 19 transmission, and rack 19 is fixed on elevating member 12. On or made into one with the lifting member 12.

As shown in FIG. 4 , the lifting member 12 is a cylinder, and the guide member 15 is a guide cylinder.

As shown in Figures 5 and 6, the utility model can also adopt an embodiment in which the lifting member 12 is a cylinder and the guide member 15 is a guide sleeve.

As shown in Figures 1, 2, and 4, in order to make the burner 3 move up and down conveniently, the intake pipe 4 adopts a flexible pipe.

As shown in Figures 2 and 4, in order to ensure that the adjustment of the burner head 3 is easy and stable, a spring 13 is set on the lifting member 12, one end of the spring 13 is offset against the burner head or the lifting member 12, and the other end of the spring 13 is offset against the guide member 15.

As shown in Figures 1 and 2, a friction disc 16 and a spring 17 are also sleeved on the shaft 2-1 of the switch 2, the friction disc 16 is offset against the stove body 1, one end of the spring 17 is offset against the back of the friction disc 16, and the other end of the spring 17 is offset against the back of the friction disc 16. The stop on axis 2-1 counteracts. In this way, the rotation flexibility of the switch 2 is effectively guaranteed and the possibility of automatic rotation of the switch 2 due to the dead weight of the burner head is prevented.

As shown in FIG. 3 , the driving gear 6 has the same number of teeth as the first driven gear 7 , and the ratio of the teeth of the driving gear 6 to the second driven gear 8 is 2:1. Effectively ensure the synchronization of burner 3 and flame regulation.

As shown in Figures 1, 2, 3, and 4, when the utility model is in use, when the fire power regulating valve 5 is in the closed state, the switch 2 knob is at the 0 degree position (that is, in the vertical position), and the burner 3 is at the highest position at this moment. Location. When the switch 2 knob is pressed inward and turned counterclockwise at the same time, the gas stove will start to supply air to ignite; as the switch 2 knob is turned counterclockwise, the gas supply will gradually increase, and the flame will also become larger. At this time, the burner 3 Then it gradually descends; when the switch 2 knob is turned counterclockwise to 90 degrees, the gas supply is the largest, the flame is the strongest, and the burner 3 is also reduced to the lowest position, that is, the distance between the burner 3 and the bottom of the pot is maximum; when the switch 2 knob continues to turn counterclockwise, the air supply of the fire control valve 5 will gradually decrease, and the flame will also become smaller. At this time, the burner 3 will gradually move up from the lowest position; when the switch 2 knob When rotating to 180 degrees, the stove fire of big burner just extinguished completely, and only little burner was still burning, and now the distance between burner 3 and the bottom of the pot was minimum. If the switch 2 knob is rotated in the opposite direction, its working process is the same as the above situation, until it is turned clockwise to 0 degrees, and then it returns to the closed state.
