Description

Technical Field

[0001] The invention relates to the field of gas stoves, in particular to a planar gas stove. Background Art

[0002] For gas stoves, the difficulty in cleaning is a major pain point for users. Especially the burner part, because it protrudes above the panel and has many concave and convex structures, it is difficult to clean. At present, there are relatively few improved technologies for easy cleaning of stoves. The existing technologies in the industry are: 1. Split burner, the burner is divided into a burner assembly and a burner base. The burner is assembled on the panel and disassembled for cleaning when it needs to be cleaned; 2. Flip burner structure, when cleaning, the user flips the burner upwards at a certain angle to free up the panel area for cleaning.

[0003] However, the above improvements also have shortcomings: 1. When a split burner structure is adopted, it is difficult for users to disassemble it for cleaning because the burner temperature is high after the stove is used. On the other hand, when the user does not clean it for a long time, oil smoke easily accumulates on the split surface, causing the burner assembly and the burner base to stick together, making them unable to be separated; 2. Since the flip structure requires a flip mechanism and a nozzle structure on the panel, it is impossible to achieve a flat panel. Summary of the invention

The burner 300 includes a burner base 310, an outer fire cover 320 and a center fire cover 330. The upper surface of the outer fire cover 320 and the upper surface of the center fire cover 330 are flush with the upper surface of the panel 200. The burner base 310 includes a bottom surface 311, and a center air channel is provided in the middle of the bottom surface 311. 313, an outer air duct 312 is provided around the bottom surface 311, a concave cavity 314 is provided between the outer air duct 312 and the central air duct 313, a decorative plate 340 is provided in the concave cavity 314, and the shape of the decorative plate 340 is adapted to the shape of the concave cavity 314; the outer fire cover 320 includes a fire surface 322, and the fire surface 322 is provided with an inclined fire hole 323, the outer air duct 312 includes an inner end surface, and the inner end surface is arranged coplanar with the fire surface 322; the lifting device 500 drives the decorative plate 314 and the pot bracket 400 to move up and down relative to the burner base 310 and the panel 200 respectively. Specifically, the lifting device 500 includes a fixed plate 510, a driving mechanism 520, a lifting support plate 530 and a connecting rod 540. The fixed plate 510 is fixedly connected to the burner base 310. The driving mechanism 520 includes a mounting portion 521 and a driving portion 522. The mounting portion 521 is fixed on the fixed plate 510. The driving portion 522 is fixedly connected to the lifting support plate 530. The lifting support plate 530 is fixedly connected to the decorative plate 340. The middle part of the connecting rod 540 is hinged to the burner base 310. One end of the connecting rod 540 is hinged to the lifting support plate 530 and the other end is hinged to the pot support 400. In this embodiment, the driving mechanism 520 is an electric screw, and a nut seat is provided in the lifting support plate 530.

[0037] When the gas stove is in use, when it is not necessary to work, the driving mechanism raises the decorative plate 340, and the pot support 314 is lowered. At this time, the surface of the gas stove is almost a plane, which is not only beautiful but also easy to clean. When the gas stove needs to work, the driving mechanism is activated, and the electric screw drives the nut seat to move downward, thereby driving the lifting support plate 530 to move downward. Since the lifting support plate 530 is fixedly connected to the decorative plate 340, the decorative plate 340 moves downward. After the decorative plate moves downward, the fire holes on the outer fire cover and the inner fire cover can be exposed; while the lifting support plate 530 is lowered, the pot support 400 is lifted up through the connecting rod 540, and the upper surface of the pot support 400 is higher than the surface of the gas stove. After the pot support is raised to the right position, the pot can be placed on the pot support 400, and then the gas is ignited from the burner, and the heat is transferred to the pot to heat the pot.

[0038] When the gas stove is no longer in use, the electric screw rod only needs to be rotated in the reverse direction to make the decorative panel rise upward and the pot support fold downward, and finally return to the same plane.

[0039] As a further preferred embodiment, a support plate 316 and a support column 317 are provided below the bottom surface of the burner base 310, the fixing plate is fixed on the support column 317, and the middle part of the connecting rod 540 is hinged to the support plate 316. The support column 317 suspends the fixing plate 510 below the burner base 310, freeing up space for the motor to be fixedly installed. At the same time, the support plate 316 provides a fulcrum for the connecting rod 540 to rotate, making the entire lifting device more compact.

The waterproof plate 600 includes a lap 610 and a water receiving edge 620. Preferably, the lap 610 is provided with a through hole, and the pot support 400 can pass through the through hole. The lap 610 abuts against the outer edge of the mounting hole 210, and the water receiving edge 620 is located below the outer fire cover 320 and abuts against the burner base 310. The burner base 310 is provided with an ear, and the burner base 310 and the water receiving edge 620 are fixedly connected by screws passing through the ear. Since the burner 300 is coplanar with the panel 200 as a whole, water on the tabletop easily flows into the interior of the gas stove. At this time, the waterproof plate 600 is used to block the mounting hole 210 on the panel 200, which can prevent water from flowing from the mounting hole 210 into the interior of the gas stove, thereby damaging the internal parts of the gas stove. The waterproof plate 600 can also prevent water from flowing into the burner 300 and can be used to fix the burner 300. When assembling, the burner 300 is first fixed on the waterproof plate 600, and then the waterproof plate 600 is sleeved in the mounting hole 210, making the product assembly more convenient.

[0044] As a further preferred embodiment, a positioning ring 315 is provided on the burner base 310, and a clamping ring is provided on the outer fire cover 320, and the clamping ring is clamped with the positioning ring 315. There are two positioning rings 315 and two clamping rings, and the heights of the two positioning rings 315 are inconsistent.

The guard plates 331 are used to cover the ignition needle 360 ​​and the thermocouple 370, and the shape of the central through hole 341 of the decorative plate 340 matches the shape of the central fire cover 330, so when the decorative plate 340 is raised, the central fire cover 330, the decorative plate 340 and the outer fire cover 320 are almost coplanar, making the burner flat and easy to clean.

[0046] In some embodiments, there may be more than two burners.

[0047] In some embodiments, in order to make the lifting of the decorative panel more stable, a guide column can be added to the lifting device, and then a guide hole is provided in the burner base, and the guide column passes through the guide hole and is connected to the decorative panel.

[0048] In some embodiments, the lifting device may be two sets of independent driving mechanisms, and the two sets of independent driving mechanisms are used to control the lifting of the pot support and the decorative panel respectively.
