Detailed Implementation

[0040] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0041] Hereinafter, with reference to the accompanying drawings, an oven 100 according to an embodiment of the present application will be described.

[0042] As shown in Figures 1-10, the oven 100 according to an embodiment of this application includes: a shell assembly 1, a burner 21, a support plate 3 for placing food, and an air inlet pipe 4. The shell assembly 1 is provided with a food loading / unloading port 141. The burner 21 and the support plate 3 for placing food are both located inside the shell assembly 1, with the burner 21 located above the support plate 3. The air inlet pipe 4 is connected to the burner 21 to supply combustible gas to the burner 21.

[0043] This shortens the heat transfer path between the burner 21 and the support plate 3, improves baking efficiency, enhances baking uniformity, and improves the taste of the food.

[0044] First, as shown in Figures 1-2, the oven 100 includes a shell assembly 1, and a baking space 10 is formed inside the shell assembly 1. The front side of the baking space 10 is provided with a take-up opening 141, through which a user can put food (e.g., pizza) into the baking space 10 and take the food out of the baking space 10 through the take-up opening 141.

[0045] The oven 100 also includes a burner 21, a support plate 3, and an air inlet pipe 4. The support plate 3 is located at the bottom of the baking space 10 and is used to support food. The burner 21 is located above the support plate 3 and at the top of the baking space 10. The air inlet pipe 4 is installed inside the housing assembly 1 and is separated from the baking space 10. The air inlet pipe 4 is connected to the burner 21 and is used to introduce combustible gas into the burner 21. The gas can be burned inside the burner 21 to radiate heat downwards, thereby cooking the food on the support plate 3. This shortens the heat transfer path between the burner 21 and the support plate 3, which helps to improve baking efficiency and allows the burner to bake the food more evenly, avoiding localized undercooking or burning, and improving the taste of the food.

[0046] It should be noted that the burner 21 is an infrared burner, and the combustible gas is a mixture of fuel gas and air. The fuel gas and air can flow into the air inlet pipe 4 separately, so that they can flow into the burner 21 after being fully mixed, thereby ensuring that the burner 21 can provide stable heat.

[0047] According to the embodiment of this application, the oven 100, by placing the burner 21 above the support plate 3, allows the burner 21 to face the support plate 3 directly, thereby shortening the heat transfer path between the burner 21 and the support plate 3, improving baking efficiency, and also improving baking uniformity and enhancing the taste of the food.

[0048] In some embodiments of this application, as shown in Figures 1-2, the oven 100 further includes an inner partition 5, which is located within and connected to the housing assembly 1. The inner partition 5 defines at least a portion of the baking space 10. The air inlet pipe 4 and the burner 21 are both located between the inner partition 5 and the housing assembly 1. The burner 21 is supported on the inner partition 5. The inner partition 5 has an exposed opening 511 communicating with the baking space 10. The burner 21 is exposed within the baking space 10 through the exposed opening 511, allowing the burner 21 to heat the baking space 10.

[0049] With the above settings, the inner partition 5 can block the heat in the baking space 10, thereby reducing heat loss, improving the heating efficiency of the oven 100, and preventing the oven 100 from getting too hot and burning the user.

[0050] In some embodiments of this application, as shown in Figures 1-2, the oven 100 further includes a lower partition 6, which is located inside and fixedly connected to the housing assembly 1. For example, the housing assembly 1 can be connected to the lower partition 6 via screws. An inner partition 5 is supported above and connected to the lower partition 6, and can also be connected to the lower partition 6 via screws. The inner partition 5 and the lower partition 6 together define the baking space 10. This allows the baking space 10 to be separated from the housing assembly 1 as much as possible, thus reducing heat loss.

[0051] Furthermore, insulation components 91 can be wrapped around the outer peripheral walls of the inner partition 5 and the lower partition 6, respectively. The insulation components 91 can be made of heat-insulating materials such as aluminum silicate cotton. This can further reduce heat loss from the baking space 10.

[0052] In some embodiments of this application, as shown in FIG1, the oven 100 of this embodiment further includes an ignition assembly 22 for igniting gas. The ignition end 221 of the ignition assembly 22 extends into the baking space 10 and is located directly below the burner 21. When combustible gas is introduced into the burner 21, the ignition assembly 22 can ignite the gas, so that the gas can burn in the burner 21, thereby allowing the burner 21 to heat the baking space 10. This ensures the operational stability of the oven 100.

[0053] Furthermore, as shown in Figure 1, the oven 100 also includes a thermocouple 23, which is used to monitor the gas combustion state in the burner 21 so that the oven 100 can stop the gas intake when the burner 21 malfunctions and shuts off. This improves the safety of the oven 100.

[0054] In some embodiments of this application, as shown in FIG1, the ignition component 22 can be disposed in the inner partition 5 so that the ignition component 22 can be disposed close to the burner 21. This reduces the layout difficulty of the ignition component 22, ensures the integration of the oven 100, and improves the design rationality of the oven 100.

[0055] In some embodiments of this application, the inner partition 5 includes a first part 51, a second part 52, and a transition connection part 53. The first part 51 extends horizontally to have an exposed opening 511. The burner 21 is supported on the first part 51. The second part 52 is connected to the end of the first part 51 that is away from the access opening 141. The second part 52 extends downward. The transition connection part 53 is connected to the first part 51 and the second part 52 respectively. The ignition assembly 22 is disposed on the transition connection part 53.

[0056] For example, as shown in Figures 1-4, the inner partition 5 includes a first part 51, a second part 52, and a transition connection part 53. The first part 51 is located at the top of the baking space 10. The first part 51 extends horizontally and has an exposed opening 511. The burner 21 extends horizontally and is supported on the first part 51. The burner 21 is arranged opposite to the exposed opening 511. The burner 21 can heat the baking space 10 through the exposed opening 511.

[0057] Meanwhile, the second part 52 can be disposed on the side of the first part 51 away from the pick-up and put-out port 141. The second part 52 extends downward and is connected to the end of the first part 51 away from the pick-up and put-out port 141. The transition connection part 53 is connected between the side of the first part 51 away from the pick-up and put-out port 141 and the upper side of the second part 52. The transition connection part 53 is configured to extend downward at an angle or bend in a direction away from the pick-up and put-out port 141, and the ignition assembly 22 is disposed on the transition connection part 53.

[0058] It is understandable that by setting the transition connection part 53, the first part 51 and the second part 52 can be smoothly connected, which is beneficial to improving the structural strength of the inner partition 5. Furthermore, by setting the ignition assembly 22 on the transition connection part 53, the ignition assembly 22 can better avoid the air intake pipe 4, thereby avoiding interference between the ignition assembly 22 and the air intake pipe 4 and improving the layout rationality of the oven 100.

[0059] In some embodiments of this application, the inner partition 5 is provided with an air inlet 531, which communicates with the space above the support plate 3 to supply air to it. For example, referring to Figures 1-4, the inner partition 5 is provided with an air inlet 531 extending through the thickness direction. The air inlet 531 is used to communicate the external space (i.e., the space outside the oven 100) with the space above the support plate 3, so that air can flow into the space above the support plate 3 through the air inlet 531, that is, into the baking space 10. The air can then flow from the baking space 10 to the burner 21, so that the gas in the burner 21 can be fully combusted. This improves the heating efficiency of the burner 21.

[0060] In some embodiments of this application, the bottom of the housing assembly 1 is provided with an air inlet 15, which is connected to the air inlet pipe 4; the oven 100 also includes a baffle 54, which is disposed inside the housing assembly 1 and is spaced apart from the air inlet 15.

[0061] For example, referring to Figures 1-2, the bottom of the housing assembly 1 (i.e., the bottom outer shell 12 and base 13 hereinafter) is provided with an air inlet 15, which communicates with the external space. The air inlet pipe 4 is connected to the air inlet 15, so that air can flow into the air inlet pipe 4 through the air inlet 15 and mix with the fuel gas flowing into the air inlet pipe 4. Simultaneously, the oven 100 may also include a baffle 54, which is disposed inside the housing assembly 1 and is positioned opposite the air inlet 15 at intervals. The baffle 54 is used to block the air inlet 15. This reduces impurities flowing into the housing assembly 1 and reduces heat leakage from the air inlet 15, thereby improving the heating efficiency of the burner 21.

[0062] In some embodiments of this application, as shown in FIG2, the baffle 54 can be connected to the inner partition 5 so that the baffle 54 and the inner partition 5 can be installed synchronously. This reduces the assembly difficulty of the oven 100 and improves its practicality.

[0063] In some embodiments of this application, as shown in FIG1, the oven 100 according to an embodiment of this application further includes a heat insulation plate 7. The heat insulation plate 7 is disposed within the housing assembly 1, connected to the inner partition 5 on the side near the loading / unloading port 141 and located at least between the burner 21 and the loading / unloading port 141. The heat insulation plate 7 is used to block the heat radiated from the burner 21 to the loading / unloading port 141, thereby reducing heat loss within the baking space 10. This improves the heating efficiency of the oven 100.

[0064] In some embodiments of this application, as shown in Figures 1 and 7, the heat insulation plate 7 includes a fixing part 71 and a surrounding plate 72. In the horizontal direction, the fixing part 71 is located between the burner 21 and the loading / unloading port 141. The fixing part 71 extends in the horizontal direction and is used to connect with the inner partition 5 to fix the heat insulation plate 7 on the inner partition 5. The surrounding plate 72 is connected below the fixing part 71 and extends downward and inclined towards the loading / unloading port 141.

[0065] The above-mentioned settings allow the heat insulation plate 7 to be used to guide the heat from the burner 21, so that the heat can flow better into the baking space 10, thereby improving the design rationality of the oven 100.

[0066] In some embodiments of this application, the included angle α1 between the enclosure 72 and the horizontal plane ranges from 45° to 90°. For example, the included angle α1 between the enclosure 72 and the horizontal plane can be set to 90°, allowing the enclosure 72 to extend downwards; alternatively, the included angle α1 between the enclosure 72 and the horizontal plane can be set to 45°, 60°, 75°, etc., allowing the enclosure 72 to extend downwards and at an angle closer to the loading / unloading port 141. This application does not impose any limitations on this. Therefore, flexible arrangement of the heat insulation board 7 can be achieved, improving its practicality.

[0067] In some embodiments of this application, the lower edge of the heat insulation plate 7 may be set not lower than the upper edge of the food loading / unloading opening 141. This avoids the heat insulation plate 7 obstructing the loading / unloading of food.

[0068] In some embodiments of this application, the inner edge of the fixing part 71 can be positioned on the outer side of the support plate 3 on the same horizontal plane. This arrangement avoids the heat insulation plate 7 obstructing the heat transfer path between the burner 21 and the support plate 3, allowing the burner 21 to better bake the food on the support plate 3, thus improving the design rationality of the oven 100.

[0069] In some embodiments of this application, as shown in Figures 1-2, both the burner 21 and the support plate 3 can be constructed as circles, with the burner 21 and the support plate 3 arranged parallel to each other and their centers coinciding. With this arrangement, food can be placed at the center of the support plate 3, allowing the burner 21 to evenly bake the food, thus preventing partial undercooking or burning and improving the practicality of the oven 100.

[0070] In some embodiments of this application, as shown in Figure 1, the distance L1 between the burner 21 and the support plate 3 can be in the range of 40mm-85mm. For example, the distance L1 between the burner 21 and the support plate 3 can be 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, etc., and this application does not impose any limitations on this. Through the above settings, the heating efficiency of the food can be guaranteed, and the placement of the food can be avoided if the distance is too small.

[0071] In some embodiments of this application, as shown in Figures 1-2, the diameter of the burner 21 can be set to be smaller than the diameter of the support plate 3. This allows for full utilization of the heat generated by the burner 21, thus improving the energy efficiency of the oven 100.

[0072] In some embodiments of this application, the diameter of the burner 21 can be set as d1, and the diameter of the support plate 3 can be set as d2, satisfying: 0.75≤d1 / d2≤0.9. That is, the ratio of the diameter d1 of the burner 21 to the diameter d2 of the support plate 3 can be set to be greater than or equal to 0.75 and less than or equal to 0.9, for example, 0.82, 0.8, 0.85, 0.88, etc. For example, when the diameter d2 of the support plate 3 is 330mm, the diameter d1 of the burner 21 can be set to be in the range of 250mm-290mm.

[0073] The above settings can reduce the size of the burner 21, which helps to save costs, while ensuring the baking efficiency of the burner 21 for food, thus improving the design rationality of the oven 100.

[0074] In some embodiments of this application, the oven 100 according to the embodiments of this application further includes a rotating component 8, which is disposed inside the housing component 1 and is connected to the support plate 3 to drive the support plate 3 to rotate.

[0075] For example, referring to Figures 1, 2, and 6, the oven 100 also includes a rotating assembly 8, which is disposed within the housing assembly 1. The rotating assembly 8 includes a rotating shaft 81, a bearing 82, and a drive motor 83. The bearing 82 is sleeved on the outside of the rotating shaft 81, and the rotating shaft 81 is rotatably supported on the housing assembly 1 via the bearing 82. The drive motor 83 is mounted on the housing assembly 1 and is poweredly connected to the rotating shaft 81. A support plate 3 is connected to the upper end of the rotating shaft 81. The drive motor 83 drives the rotating shaft 81 to rotate, thereby causing the support plate 3 to rotate, and thus allowing the food on the support plate 3 to rotate synchronously. This allows for more even baking of the food and improves its texture.

[0076] In some embodiments of this application, as shown in Figures 1 and 6, the support plate 3 includes a base plate 31 and a bearing portion 32. The base plate 31 has a groove in its center, and the bottom wall of the groove has a connecting hole. A fastener 92 can pass through the connecting hole and connect to the upper end of the rotating shaft 81 to fix the base plate 31 onto the rotating shaft 81. Simultaneously, the base plate 31 can be configured to have an upwardly open mounting space, and the bearing portion 32 can be a pizza stone, which can be replaceably installed within the mounting space. This facilitates subsequent maintenance of the support plate 3 and improves the design rationality of the support plate 3.

[0077] In some embodiments of this application, the housing assembly 1 includes an upper outer shell 11, a lower outer shell 12, and a base 13. The upper outer shell 11 is connected to the top of the lower outer shell 12, and the lower outer shell 12 is disposed inside the base 13. The rotating assembly 8 is disposed in the lower outer shell 12. The air intake pipe 4 includes a connecting pipe 41 and a delivery pipe 42. The first end of the connecting pipe 41 is connected to the burner 21, and the second end of the connecting pipe 41 is connected to the delivery pipe 42. The delivery pipe 42 is disposed between the lower outer shell 12 and the base 13.

[0078] For example, referring to Figures 1-2, the housing assembly 1 includes an upper outer shell 11, a lower outer shell 12, and a base 13, arranged sequentially from top to bottom. The upper outer shell 11 is supported on top of and connected to the lower outer shell 12. A mounting cavity is defined between the upper outer shell 11 and the lower outer shell 12. An inner partition 5 and a lower partition 6 are installed in the mounting cavity, which together define a baking space 10. The lower outer shell 12 is disposed within the base 13, which supports the upper outer shell 11 and the lower outer shell 12.

[0079] Meanwhile, the rotating assembly 8 can be mounted on the bottom housing 12. At least a portion of the rotating assembly 8 extends above the lower partition 6 to connect with the side of the support plate 3 away from the burner 21. The bottom housing 12 is used to support the rotating assembly 8 so that the rotating assembly 8 can drive the support plate 3 to rotate stably.

[0080] As shown in Figures 7-9, the intake pipe 4 includes a connecting pipe 41 and a delivery pipe 42. The connecting pipe 41 is installed inside the mounting cavity, and the delivery pipe 42 is located between the bottom outer shell 12 and the base 13. The first end of the connecting pipe 41 is connected to the burner 21, and the second end of the connecting pipe 41 passes through the bottom outer shell 12 and is connected to the delivery pipe 42. The delivery pipe 42 is used to communicate with an external pipe (such as a gas pipe), allowing the external pipe to supply gas into the delivery pipe 42, and the gas can flow into the connecting pipe 41 along the delivery pipe 42. The second end of the connecting pipe 41 is also connected to the external space. Due to the relatively fast flow velocity of the gas, the gas can carry air into the connecting pipe 41, where the gas and air mix and then flow into the burner 21 after thorough mixing.

[0081] The above-mentioned design reduces the structural complexity and processing difficulty of the oven 100. The bottom outer shell 12 separates the baking space 10 from the conveying pipe 42, which helps reduce the probability of gas leakage into the baking space 10 and improves the safety of the oven 100. In addition, by mounting the rotating component 8 on the bottom outer shell 12, the rotating component 8 and the burner 21 can be located on opposite sides of the support plate 3, which helps protect the rotating component 8 and improves its operational stability.

[0082] In some embodiments of this application, the second end of the connecting pipe 41 is provided with a fixed bracket 43, the conveying pipe 42 is fixed to the fixed bracket 43, the bottom shell 12 is provided with an opening 121, and at least one of the second end of the connecting pipe 41, the fixed bracket 43 and the conveying pipe 42 passes through the opening 121.

[0083] For example, as shown in Figures 1-10 and 7-10, the second end of the connecting pipe 41 is provided with a fixed bracket 43. The fixed bracket 43 includes a connecting bottom wall 431 and connecting side walls 432 located on both sides of the connecting bottom wall 431. The connecting bottom wall 431 is arranged parallel to and spaced apart from the second end of the connecting pipe 41. The two sides of the connecting bottom wall 431 are respectively connected to the connecting pipe 41 through the connecting side walls 432. The fixed bracket 43 also defines an air replenishment space 433, which is used to connect the connecting pipe 41 with the external space.

[0084] The bottom wall 431 is provided with mounting holes, and nuts 434 are fixed on the bottom wall 431 corresponding to the mounting holes. The end of the conveying pipe 42 is provided with a hollow connecting joint 421. The connecting joint 421 passes through the mounting hole and is screwed into the nut 434 to fix the conveying pipe 42 on the fixed bracket 43. The conveying pipe 42 can also be connected to the connecting pipe 41 through the connecting joint 421.

[0085] The connecting pipe 41 is installed inside the mounting cavity, and the bottom outer shell 12 has an opening 121. At least one of the second end of the connecting pipe 41, the fixing bracket 43, and the delivery pipe 42 passes through the opening 121, so that the connecting pipe 41 and the delivery pipe 42 can be connected through the opening 121. It should be noted that the bottom outer shell 12 and the base 13 are respectively provided with air inlets 15, which are used to communicate with the external space.

[0086] For example, a fixed bracket 43 can be installed inside the opening 121, and the air replenishment space 433 of the fixed bracket 43 can be directly connected to the air inlet 15 on the bottom outer shell 12 and the air inlet 15 on the base 13; or, a delivery pipe 42 can be installed inside the opening 121, so that the fixed bracket 43 is located above the bottom outer shell 12, and the air replenishment space 433 of the fixed bracket 43 can be directly connected to the air inlet 15 on the bottom outer shell 12, and can also be connected to the air inlet 15 on the base 13 through the opening 121; or, a connecting pipe 41 can be installed inside the opening 121, so that the fixed bracket 43 is located below the bottom outer shell 12, and the air replenishment space 433 of the fixed bracket 43 can be directly connected to the air inlet 15 on the base 13, and can also be connected to the air inlet 15 on the bottom outer shell 12 through the opening 121.

[0087] The above settings can improve the installation stability between the delivery pipe 42 and the connecting pipe 41, ensure a stable gas supply, and allow for flexible arrangement of the air inlet pipe 4, reducing the layout difficulty of the oven 100.

[0088] In some embodiments of this application, as shown in Figures 1-2, the housing assembly 1 further includes a door frame 14, which can be die-cast. The door frame 14 is connected to the upper outer shell 11 and the lower outer shell 12 respectively and is used to define the loading / unloading opening 141. This reduces the molding difficulty of the loading / unloading opening 141, lowers the processing difficulty of the housing assembly 1, and improves the structural stability of the housing assembly 1, thereby increasing the reliability of the oven 100.

[0089] In some embodiments of this application, as shown in Figures 1-2, the base 13 is provided with a shielding part 131 corresponding to the opening 121. The shielding part 131 is spaced apart from the opening 121 and is used to shield the opening 121 from the outside. This prevents the opening 121 from opening directly to the outside, which helps to reduce impurities flowing into the oven 100 and improves the overall aesthetics of the oven 100.

[0090] In some embodiments of this application, as shown in FIG1, a heat insulation element 91 may be provided on the lower side of the bottom outer shell 12. The heat insulation element 91 may be made of heat insulation materials such as aluminum silicate cotton. The heat insulation element 91 is used to block the heat transfer from the baking space 10 to the base 13. This helps to protect the components on the base 13, such as the power supply, pulse, and switch, and improves the reliability of the oven 100.
