Description

Technical Field

[0001] The utility model relates to the technical field of pizza machines, in particular to a rotating structure for a pizza machine and a pizza machine. Background Art

[0002] Pizza is a kind of food covered with sauce and fillings on fermented round bread. It is very popular because users can mix different sauces and fillings according to their preferences. When making pizza, a special pizza oven is usually required.

[0003] However, the existing pizza oven structures are mostly fixed. When baking pizza, in order to avoid uneven heating of the pizza and the occurrence of burning, the user needs to regularly open the oven cover door of the oven body and use tools such as shovels and forks to rotate the pizza in the oven body. Not only is the operation inconvenient, but frequent opening of the oven cover door will also cause the baking temperature of the pizza in the oven body to change, thereby affecting the taste of the pizza; for example, publication number CN215383307U-Heating structure for pizza oven and pizza oven discloses a heating structure for pizza oven and a pizza oven, comprising an oven cavity, the front side of the oven cavity is open, the top surface and the bottom surface of the oven cavity protrude outward to form an installation recess, the left side or the right side of the installation recess is provided with a projection, and the installation recess located on the bottom surface is covered with a baking plate; a heating coil, the heating coil is respectively installed at the top and bottom of the oven cavity, the heating coil is installed in the installation recess, the wiring terminal of the heating coil extends out from the projection, and the pizza is baked through the heating coil. The above structure requires a spatula to flip the pizza when baking so that the pizza can be heated evenly, which causes inconvenience.

[0004] Another example is publication number CN218484366U-A pizza oven with four-sided pizza stones, which discloses a pizza oven with four-sided pizza stones, including a furnace body, a baking cavity for baking pizza formed in the furnace body, and heating tubes are arranged on the upper and lower sides of the baking cavity, characterized in that a pizza stone assembly is set up at a position between the two heating tubes in the baking cavity, and the pizza stone assembly includes two first pizza stones arranged symmetrically up and down and two second pizza stones arranged symmetrically left and right, the first pizza stones and the second pizza stones cooperate with each other and are used to wrap the upper, lower, left and right sides of the pizza, so that space for placing pizza is left on the front and back sides of the pizza stone assembly, and the front side of the pizza stone assembly corresponds to the door body of the furnace body. Although the above structure can make the pizza food evenly heated when baking through the arrangement of the four-sided pizza stones, the overall structure is complicated and inconvenient to use, and the pizza stone structure is increased, which correspondingly increases the cost of use.

[0019] In some embodiments, the transmission shaft and the driven gear are fixedly connected to ensure synchronous movement of the two; optionally, the transmission shaft and the driven gear are flatly connected.

[0020] By adopting the above solution, the rotation axis of the driving gear is perpendicular to the rotation axis of the driven gear, so that the driving gears are arranged relatively horizontally, which fully utilizes the space and is conducive to space arrangement.

[0021] In some embodiments, the driving gear is arranged on the side of the driven gear away from the rotating tray; and, the side of the driven gear away from the rotating tray is circumferentially formed with a first gear portion around the rotation axis of the driven gear, and the driving gear is circumferentially formed with a second gear portion around its rotation axis, and the first gear portion and the second gear portion are meshed for transmission.

[0022] In some embodiments, the driving gear is a small gear and the driven gear is a large gear, which can play a role of deceleration, so that the transmission shaft drives the rotation movement of the rotating tray to be smoother.

[0023] By adopting the above scheme, the driving motor can drive the driving gear to rotate around its own centerline axis; since the second gear portion of the driving gear and the first gear portion of the driven gear are meshed and transmitted, the driven gear can be driven to rotate around its own centerline axis; since the driven gear and the transmission shaft are fixedly connected, the transmission shaft can be driven to rotate around its own centerline axis, and since the rotating tray is placed on the top end of the transmission shaft, the rotating tray can be driven to rotate around its own centerline axis.

[0026] In some embodiments, the storage box includes an upper box body and a lower box body that are detachably connected to facilitate assembly and subsequent maintenance of the rotating mechanism.

[0027] In some embodiments, a fixing plate for fixing the driving motor is disposed in the storage box, and the driving gear is connected to the output shaft of the driving motor.

[0028] The solution adopted by the utility model to solve the above technical problems is a pizza machine, which includes a shell and a rotating structure for the pizza machine as described above and connected to the shell.

[0032] In some embodiments, the shell includes a first shell, a second shell and a third shell arranged in sequence from the outside to the inside, and the baking cavity is formed in the third shell. Since there is a gap between the first shell and the second shell, and a gap between the second shell and the third shell, very little heat in the baking cavity is transferred to the outside, thereby reducing the temperature of the first shell and preventing burns during use; and the first shell is provided with heat dissipation holes at the top and bottom ends thereof to reduce the temperature of the first shell.

[0033] In some embodiments, the top of the third shell and the top of the second shell are both provided with openings, and the back side of the first shell is provided with an air inlet that can be connected to the outside; when in use, the first heating tube and the second heating tube work simultaneously, and the second heating tube is located below the rotating tray, so as to achieve uniform heating of the bottom of the rotating tray; the heating tube on the top directly heats the air in the baking cavity, and through air transfer, it can achieve uniform heating of the top of the rotating tray; at the same time, through the air inlet of the first shell and the openings of the second shell and the third shell, fresh air can be supplemented and exchanged, thereby maintaining air circulation during the heating process and enhancing the taste of the pizza.

[0060] like Figure 1-Figure 4As shown, the utility model discloses a rotating structure for a pizza machine, including a rotating tray 10, one end of which is formed with a baking end 11 for placing food; a rotating mechanism 20, which is connected to the side of the rotating tray 10 away from the baking end 11, and is used to drive the rotating tray 10 to rotate around its own central axis; wherein the rotating mechanism 20 includes a transmission shaft 21 connected to the rotating tray 10 and extending along the central axis of the rotating tray 10, a driven gear 22 connected to the other end of the transmission shaft 21, a driving gear 23 meshing with the driven gear 22, a driving motor 24 connected to the driving gear 23, and a control switch 25 electrically connected to the driving motor 24. In some embodiments, the baking end 11 of the rotating tray 10 is radially arranged with two annular protrusions 111 with different shaft diameters around its central axis to support pizzas of different sizes, and has a wide range of uses. By adopting the above scheme, the rotating tray 10 can be driven to rotate in the pizza machine through the rotating mechanism 20, so that the pizza can be baked more evenly in the pizza machine and is not easy to burn. This effectively solves the problem that the existing fixed pizza oven can only rotate the pizza in the pizza machine by opening the pizza door and using tools such as shovels and forks, and the operation is low in convenience; and the stability of the baking temperature of the pizza in the pizza machine is ensured, thereby ensuring the taste of the pizza; at the same time, the entire rotating mechanism 20 has a simple structure and a stable transmission method. The rotation and stop of the rotating tray 10 can be controlled by controlling the switch 25, and the operation is convenient and simple.

[0061] In some embodiments, the end of the transmission shaft 21 close to the rotating tray 10 is sleeved with a first positioning sleeve 26, and the end of the transmission shaft 21 close to the driven gear 22 is sleeved with a second positioning sleeve 27, and the first positioning sleeve 26 and the second positioning sleeve 27 are coaxially arranged.

In some embodiments, the end of the first positioning sleeve 26 facing away from the second positioning sleeve 27 is formed with a supporting end surface 261 for supporting the rotating tray 10. In some embodiments, the first positioning sleeve 26 includes a first positioning portion 262 and a second positioning portion 263 arranged in sequence along the length direction of the transmission shaft 21, and the second positioning portion 263 is arranged close to the second positioning sleeve 27, and the top end of the first positioning portion 262 is formed with the supporting end face 261; the axial diameter of the first positioning portion 262 is larger than the axial diameter of the second positioning portion 263, so that the size of the supporting end face 261 is a large-size end face, which is sufficient to support the rotating tray 10, thereby ensuring the stability of the rotating tray 10 on the first positioning sleeve 26, thereby ensuring the stability of the transmission shaft 21 and the rotating tray 10 when they rotate synchronously.

[0062] In some embodiments, the rotation axis of the driven gear 22 coincides with the rotation axis of the transmission shaft 21; the rotation axis of the driving gear 23 is perpendicular to the rotation axis of the driven gear 22.

With the above scheme, the rotation axis of the driving gear 23 is perpendicular to the rotation axis of the driven gear 22, so that the driving gear 23 is relatively horizontally arranged, making full use of the space and facilitating space arrangement. In some embodiments, the driving gear 23 is arranged on the side of the driven gear 22 away from the rotating tray 10; and the side of the driven gear 22 away from the rotating tray 10 is circumferentially formed with a first gear portion 221 around the rotation axis of the driven gear 22, and the driving gear 23 is circumferentially formed with a second gear portion 231 around its rotation axis, and the first gear portion 221 and the second gear portion 231 are meshed and transmitted. In some embodiments, the driving gear 23 is a small gear and the driven gear 22 is a large gear, which can play a role in reducing speed, so that the transmission shaft 21 drives the rotating tray 10 to rotate more smoothly. With the above scheme, the driving motor 24 can drive the driving gear 23 to rotate around its own centerline axis; because the second gear portion 231 of the driving gear 23 and the first gear portion 221 of the driven gear 22 are meshed and driven, the driven gear 22 can be driven to rotate around its own centerline axis; because the driven gear 22 and the transmission shaft 21 are fixedly connected, the transmission shaft 21 can be driven to rotate around its own centerline axis, and because the rotating tray 10 is placed on the top of the transmission shaft 21, the rotating tray 10 can be driven to rotate around its own centerline axis.

In some embodiments, the storage box 30 includes a detachably connected upper box body 33 and a lower box body 34, so as to facilitate the assembly and subsequent maintenance of the rotating mechanism 20.

In some embodiments, the shell 40 includes a first shell 47, a second shell 48 and a third shell 49 arranged in sequence from the outside to the inside, and the baking cavity 41 is formed in the third shell 49. Since there is a gap between the first shell 47 and the second shell 48, and a gap between the second shell 48 and the third shell 49, very little heat in the baking cavity 41 is transferred to the outside, thereby reducing the temperature of the first shell 47 and preventing burns during use; and the first shell 47 is provided with heat dissipation holes at the top and bottom ends thereof to reduce the temperature of the first shell 47. In some embodiments, the top of the third shell 49 and the top of the second shell 48 are both provided with an opening 60, and the back side of the first shell 47 is provided with an air inlet 70 that can be connected to the outside; when in use, the first heating tube 42 and the second heating tube 43 work simultaneously, and the second heating tube 43 is located below the rotating tray 10, so that it can achieve uniform heating of the bottom of the rotating tray 10; the top heating tube directly heats the air in the baking chamber 41, and through air transfer, it can achieve uniform heating of the top of the rotating tray 10; at the same time, through the air inlet 70 of the first shell 47, and the openings 60 of the second shell 48 and the third shell 49, fresh air can be supplemented and exchanged, air circulation is maintained during the heating process, and the taste of the pizza is enhanced.
