[0049] Embodiment 2

[0050] Reference Figures 1-3The embodiment provides a reversible gas stove, which comprises a burner as described in the embodiment 1, a turnover mechanism 2 and a gas control module, wherein the gas control module comprises a stove shell 3, a gas path system 4 and a control assembly 5. A control area 321 is arranged at the front end of the top of the stove shell 3, the control assembly 5 is arranged in the stove shell 3 and abuts against the bottom of the control area 321. The turnover mechanism 2 is detachably arranged at the rear end of the top of the stove shell 3, the burner 1 is arranged at the left and right sides of the rear end of the turnover mechanism 2, and the hinged part of the burner 1 is rotationally connected with the turnover mechanism 2. The gas path system 4 comprises two nozzle groups, the two nozzle groups are arranged at the left and right side walls of the front end of the turnover mechanism 2 and are in communication with the air inlet hole groups of the two burners 1, in the embodiment, the nozzle group comprises two nozzles 41 arranged in the front-rear direction, and correspondingly, the air inlet hole group comprises two side air inlets 112 arranged in the front-rear direction.

[0051] It can be seen that the two burners 1 are rotationally arranged on the top of the stove shell 3 through the same turnover mechanism 2, the structure is more compact, the space occupied is smaller, the material and installation costs are significantly reduced, the minimization of space occupation is realized, the table space occupied by the cleaning dead angle of the gas stove is effectively reduced, the gas stove and the table are better cleaned. In addition, by integrating the two nozzle groups on the turnover mechanism 2, the length of the gas connection pipeline is shortened, and the efficiency and safety of the gas stove are further improved.

[0052] In the embodiment, the burner 1 can be switched between the flat mode and the turnover mode, and the maximum turnover angle of the burner 1 towards the upper rear is ∈ [90°, 180°), so that after the burner 1 is turned up to the maximum turnover angle, the burner 1 is effectively prevented from being inclined forward or unstable due to the action of its own gravity, and the operation safety and reliability are ensured.

[0053] Reference Figures 1-3 and Figures 9-12The turnover mechanism 2 comprises a fixed seat 21 and a rotating shaft assembly 22. The first shaft hole 211 is formed through the left and right side walls of the rear end of the fixed seat 21. The cavity 212 is formed at the front end of the fixed seat 21 and opens downward. The cavity 212 is configured to accommodate the upper end of the gas pipe group in the gas path system 4. The mounting hole group is arranged in the left and right side walls of the front end of the fixed seat 21 and communicates with the cavity 212. The mounting hole group is configured to mount the nozzle group in the gas path system 4. The rotating shaft assembly 22 is transversely arranged in the first shaft hole 211, and the opposite ends of the rotating shaft assembly 22 protrude out of the left and right side walls of the fixed seat 21. In this embodiment, the opposite ends of the rotating shaft assembly 22 are used to rotateably connect the two burners 1. Thus, the same turnover mechanism 2 can rotateably connect the two burners 2. Compared with the existing double burner turnover gas stove which generally uses independent turnover mechanisms, the structure is more compact, occupies less space, and is beneficial to reduce material and installation costs, and at the same time, it is beneficial to shorten the length of the gas connection pipeline.

[0054] Reference Figures 1-3 When the hinged parts in the two burners 1 are rotateably mounted on the top of the stove shell 3 by the same turnover mechanism 2, the side gas inlets 112 in the two burners 1 can communicate with the nozzles 41 mounted on the mounting hole group of the fixed seat 21. Thus, the burner 1 can be switched between the flat mode (see the right burner in Figure 1 and the turnover mode (see the left burner in Figure 1 ). That is, the burner 1 can be turned over relative to the stove shell 3, effectively reducing the cleaning dead angle and the occupied countertop space of the gas stove, and making the gas stove and the countertop easier to clean.

[0055] Reference Figures 9-12 The fixed seat 21 is provided with at least one positioning groove 2111 which communicates with the first shaft hole 211. The outer surface of the middle part of the rotating shaft assembly 22 is provided with at least one positioning protrusion 221. The positioning protrusion 221 is inserted into the positioning groove 2111. Thus, the rotating shaft assembly 22 is quickly pre-positioned by the cooperation of the at least one positioning groove 2111 and the at least one positioning protrusion 221, effectively preventing the rotating shaft assembly 22 from rotating relative to the fixed seat. In this embodiment, the number of the positioning groove 2111 and the positioning protrusion 211 is two. The two positioning grooves 2111 are arranged on the opposite outer sides of the first shaft hole 211 and communicate with the first shaft hole. The two positioning protrusions 221 protrude out of the opposite outer sides of the outer surface of the middle part of the rotating shaft assembly 22.

[0056] Reference Figures 9-12Further, the turnover mechanism 2 further comprises a locking member 23, a fixing hole 214 is formed in the rear side wall of the fixing seat 21 and is in communication with the first shaft hole 211, the locking member 23 is preferably a screw or a positioning pin, and is arranged from the rear to the front in the fixing hole 214 and is locked or unlocked with the rotating shaft assembly 22, so as to fix the rotating shaft assembly on the fixing seat and further ensure the stability and reliability of the turnover process of the rotating shaft assembly.

[0057] With reference to Figures 9-10 Further, the left and right side walls of the rear end of the fixing seat 21 are respectively provided with outwardly extending support tables 215, the support tables 215 are located below the rotating shaft assembly 22 and are used for reliably supporting the hinged part in the burner 1, so as to avoid the direct contact between the burner 1 and the top of the cooktop shell 3 during the turnover process. Specifically, the top of each support table 215 is concavely provided with a rotating groove 2151 which is open upward and is arranged along the length direction of the support table 215, and the rotating groove 2151 is adapted to accommodate part of the hinged part in the burner 1.

When the hinged part of the rear side wall of the burner 1 is turned over to the guide surface 2152 of the fixing seat 21 and is interfered to complete the rear inclination of ≥90° during the turnover, the burner 1 is effectively prevented from being inclined forward or unstable due to the action of gravity. Conversely, when the burner 1 is turned over downward to the flat mode, the hinged part of the rear side wall of the burner 1 is interfered by the front part of the top of the support table 215 which is located in front of the rotating groove 2151 to complete the positioning and fixing, and at this time, a space is left between the bottom of the burner 1 and the top of the cooktop bottom shell 3 to prevent the direct contact between the burner 1 and the top of the cooktop bottom shell 3.
