[0001] The utility model relates to the technical field of vertical rice machines, in particular to an automatic lifting structure of a central rod of a burner of a vertical rice machine. Background Art

[0002] The vertical rice machine is commonly used in hotels, restaurants and other places where a large amount of rice needs to be steamed and cooked. The cleaned raw rice is evenly spread on a square plate, and after adding a proper amount of water, the square plate is placed in the vertical rice machine for fixing. After closing the movable door of the vertical rice machine, the heating device in the vertical rice machine is started to heat and steam the square plate and the raw rice and water contained therein to finally obtain rice.

[0003] However, the burner of the current vertical rice maker is usually fixed when in use, and the square plate containing raw rice is heated by the heat emitted by the burner. However, when the plate is taken out after steaming, it is easy to cause wear on the burner head due to the friction between the bottom surface of the square plate and the burner, which in turn affects the safe use of the burner and its normal service life, and reduces the use effect of the burner. In view of this, we propose an automatic lifting structure for the center rod of the burner of a vertical rice maker. Utility Model Content

[0027] Furthermore, there are two groups of connecting members 4, and the two groups of connecting members 4 are mirror-imaged on the left and right sides of the table 5. Through the setting of the connecting members 4, the table 5 is kept in a horizontal installation state inside the body 1. At the same time, the burner 7 is arranged at the center of the table 5, and a circular hole matching the outer diameter of the transmission column 6 is opened at the center of the table 5, and the transmission column 6 is arranged inside the circular hole, so that the movement of the burner 7 on the table 5 can only maintain vertical movement without tilting or offset, so that the burner 7 can contact with the cooking plate placed inside the body 1 and heat the inside of it. The raw rice is heated. In addition, the sizes of the main L-shaped transmission member 83 and the auxiliary L-shaped transmission member 87 are set to be exactly the same, and the end of the auxiliary L-shaped transmission member 87 away from the auxiliary connecting rod 88 is movably connected with another group of hooks 84, and the group of hooks 84 is transmission-connected with another group of transmission ear plates 82 on the side wall of the closed door 3, so that when the closed door 3 deflects to the side away from the center of the machine body 1 with the rotating shaft 2 as the rotation center, the transmission ear plate 82 will synchronously perform a circular motion. At this time, under the pull of the hook 84, the main L-shaped transmission member 83 and the auxiliary L-shaped transmission member 87 each rotate with the connection portion between it and the mounting plate 81 as the rotation center.

[0028] In addition, the two ends of the spring 86 are respectively fixedly connected to the arc-shaped outer walls of the main connecting rod 85 and the auxiliary connecting rod 88, so that through the setting of the spring 86, when the closed door 3 is in the open state, the elastic force of the spring 86 will give the closed door 3 a movement tendency to rotate in the opposite direction with the rotating shaft 2 as the rotation center, so that when the closed door 3 is kept in the closed state, this state can be maintained, thereby ensuring that the closed door 3 will not be opened due to the increase in internal temperature during steaming in the vertical rice machine, thereby causing air leakage or cooling. At the same time, the transmission rod 811 penetrates the mounting plate 81, and the transmission rod 811 is rotatably connected to the mounting plate 81, so that when the main L-shaped transmission member 83 uses the connection portion between it and the mounting plate 81 as the rotation When the rotation center rotates, the main connecting rod 85 pulls the end of the connecting rod 89, thereby prompting the flip rod 810 to rotate with the connection part between the transmission rod 811 and the mounting plate 81 as the rotation center.

[0030] In the present invention, when the staff opens the closed door 3, the closed door 3 deflects to the side away from the center of the machine body 1 with the rotating shaft 2 as the rotation center. At this time, the transmission ear plate 82 pulls the hook 84, so that the main L-shaped transmission member 83 and the auxiliary L-shaped transmission member 87 will deflect with the connection between them and the mounting plate 81 as the rotation center. At this time, the end of the main L-shaped transmission member 83 and the main connecting rod 85 are displaced, so that the connecting rod 89 pulls the bottom end of the flip rod 810, prompting the flip rod 810 to rotate. 810 and the transmission rod 811 will rotate with the connection between the transmission rod 811 and the mounting plate 81 as the rotation center, thereby causing the arc portion 812 to rotate between the table 5 and the deflection plate 814, so that the deflection plate 814 deflects downward with the hinge rod 813 as the rotation center, and cooperates with the clamping plate 815 and the transmission column 6 to move the burner 7 downward to leave a safe distance, so that the staff can put the cooking plate containing raw rice and water into the interior of the body 1 after opening the closed door 3.

[0031] After the cooking plate is placed, the staff closes the closed door 3. At this time, the closed door 3 will deflect toward the inner wall of the body 1 with the rotating shaft 2 as the rotation center, and then under the influence of the elastic force of the spring 86, the main connecting rod 85 and the auxiliary connecting rod 88 will move toward the side of the vertical central axis of the body 1 to cause the main L-shaped transmission member 83 and the auxiliary L-shaped transmission member 87 to reverse, and then cooperate with the connecting rod 89 and the flip rod 810, so that the transmission rod 811 drives the arc portion 812 to release the downward squeezing force on the deflection plate 814, and then under the elastic force of the reset spring 816, the burner 7 drives the transmission column 6 to move upward, so that the flame head at the top of the burner 7 fits with the bottom surface of the cooking plate placed inside the body 1, thereby maximizing the heating efficiency of the burner 7 during the cooking operation.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
