Abstract
Description
Technical Field
[0001] The utility model relates to the field of baking equipment, in particular to a food baking utensil. Background Art
[0002] Existing baking equipment with food rotation function has a rotatable baking tray or grill in the cooking cavity, and the motor is directly connected to the baking tray or grill through a metal shaft. During the food heating process, some heat is easily transferred to the motor through metal heat conduction, which not only causes heat loss and reduces the heating efficiency of the food, but also causes the motor temperature to rise too high, affecting its lifespan.
[0003] For example, patent CN106859378B discloses a grill pan assembly with a grill pan inside a cooking chamber and a motor and drive shaft outside the cooking chamber. The motor drives the grill pan via the drive shaft to improve the uniformity of food heating. This solution fails to consider heat transfer. Because the drive shaft directly contacts the grill pan, if the drive shaft is made of a standard material, some of the heat from the grill pan can easily be transferred to the motor through the drive shaft during food heating. This results in low heating efficiency and excessive motor temperature rise, shortening the motor's lifespan.
[0004] In addition, in the above solution, the motor is installed on the outer wall of the cooking cavity through a fixing bracket. When the fixing bracket is made of general materials, heat transfer will occur between the cooking cavity and the motor, further causing the motor temperature to be too high, seriously affecting the performance and life of the motor.

[0046] like Figures 1 to 7 As shown, the present application provides a food grilling utensil, comprising a shell, a cooking cavity 10 arranged in the shell and a driving mechanism arranged outside the cooking cavity 10, a food grill 11 is provided in the cooking cavity 10, the driving mechanism is used to drive the food grill 11 to rotate around a horizontal axis, a rotatable transmission shaft 12 is provided on the side wall of the cooking cavity 10, the driving mechanism includes a motor 13 and an insulating coupling 14, one end of the transmission shaft 12 is fixedly connected to the rotating shaft of the food grill 11, and the other end is transmission-connected to the output shaft 131 of the motor through the insulating coupling 14.
[0047] The food grilling device of the present invention, by providing a heat-insulating coupling 14 between the drive shaft 12 and the motor 13, can reduce heat conduction between the drive shaft 12 and the motor 13 while ensuring transmission efficiency. This can prevent the loss of some heat from the food grill 11, resulting in low heating efficiency, and can also prevent the motor 13 from overheating, which would affect its performance and lifespan. The heat-insulating coupling 14 is made of a material with a low thermal conductivity coefficient, which can reduce the amount of heat transferred to the motor 13 via the heat-insulating coupling 14, providing a reliable insulation effect. When the food grilling device is in operation, the motor 13 drives the drive shaft 12, which in turn drives the food grill 11 to rotate, achieving rotational heating of the food on the grill.
[0048] As a preferred embodiment, Figure 1 、 Figure 3 or Figure 5 As shown, the thermal insulation coupling 14 has a first hole 141 for inserting the output shaft 131 of the power supply motor. A screw (not shown) is provided on the side wall of the thermal insulation coupling 14 above the first hole 141 for locking the thermal insulation coupling 14 and the output shaft 131 of the motor. The thermal insulation coupling 14 and the output shaft 131 of the motor are plugged together for easy installation. The use of screws to vertically lock the thermal insulation coupling 14 and the output shaft 131 of the motor prevents relative movement between the two, which helps to improve transmission stability and reliability.
[0049] Furthermore, the thermal insulation coupling 14 is provided with a second hole 142 for inserting the drive shaft 12. A screw (not shown) is provided on the side wall of the thermal insulation coupling 14 above the second hole 142 for locking the thermal insulation coupling 14 and the drive shaft 12. The thermal insulation coupling 14 and the drive shaft 12 are plug-fitted together for easy installation. The use of the screw to vertically lock the thermal insulation coupling 14 and the drive shaft 12 prevents relative movement between the two, thereby improving transmission stability and reliability.
[0050] As a preferred embodiment, the driving mechanism includes a heat-insulating connecting bracket 15 , and the motor 13 is fixed to the outer wall of the cooking cavity 10 via the heat-insulating connecting bracket 15 .
[0051] For a general motor mounting bracket, as the temperature in the cooking cavity 10 becomes higher and higher during the food heating process, the motor mounting bracket fixed on the outer wall of the cooking cavity 10 will inevitably be affected by heat conduction and reach a high temperature state. It is easy for the heat of the motor mounting bracket to be transferred to the motor 13, causing the temperature of the motor 13 to be too high. In order to solve this problem, the present application adopts an insulating connecting bracket 15 with a low thermal conductivity coefficient to reduce heat conduction, which can prevent the temperature of the motor 13 from rising too high and affecting the heating efficiency in the cooking cavity 10 and the life of the motor 13.
[0052] As a preferred embodiment of this embodiment, the heat-insulating connecting bracket 15 is provided between the heat-insulating coupling 14 and the motor body 132 of the motor 13. Figure 2 As shown, the thermal insulation coupling 14 and the thermal insulation connecting bracket 15 are used to form double thermal insulation protection, which can strengthen the thermal insulation of the motor body 132 and make the motor body 132 work at a suitable temperature to ensure its performance and life.
[0053] Specifically, such as Figure 1 As shown, the outer wall of the cooking cavity 10 is provided with a fixing column 101 protruding outward, and the heat-insulating connection bracket 15 is provided with a screw column 151 corresponding to the fixing column 101. The fixing column 101 and the screw column 151 are fastened together by screws.
[0054] As a preferred embodiment, the driving mechanism includes a heat-insulating first connecting bracket 16 and a second connecting bracket 17 , the motor 13 is fixed to the first connecting bracket 16 , and the first connecting bracket 16 is fixed to the outer wall of the cooking cavity 10 through the second connecting bracket 17 .
[0055] like Figure 3 As shown, the use of multiple thermal insulation brackets can increase the distance between the motor 13 and the cooking cavity 10. In addition, the physical insulation of the multiple thermal insulation brackets can further reduce the operating temperature of the motor 13 and optimize the thermal insulation effect.
[0056] Specifically, the outer wall of the cooking cavity 10 is provided with a fixing column 101 protruding outward, and the second connecting bracket 17 is provided with a screw hole 171 corresponding to the fixing column 101, and the fixing column 101 and the screw hole 171 are fastened together by screws; the first connecting bracket 16 is provided with a screw column 151, and the second connecting bracket 17 is provided with a screw hole corresponding to the screw column 151, and the screw column 151 and the screw hole are fastened together by screws.
[0057] As a preferred embodiment of this embodiment, the heat-insulating coupling 14 is provided between the first connecting bracket 16 and the second connecting bracket 17. Figure 4 As shown, the second connecting bracket 17, the insulating coupling 14 and the first connecting bracket 16 form triple thermal insulation protection, which can enhance the thermal insulation of the motor body 132, so that the motor body 132 works at a suitable temperature, ensuring its performance and life.
[0058] As a preferred embodiment, the driving mechanism includes a motor bracket 18 for fixing the motor 13, and the motor bracket 18 is fixed to the housing 19 so that the motor bracket 18 is isolated from the side wall of the cooking cavity 10. Figure 5 As shown, this embodiment can prevent the heat of the cooking cavity 10 from being transferred to the motor 13 through the motor bracket 18, thereby strengthening the heat insulation of the motor 13, which is beneficial to extending the service life of the motor 13, and has lower requirements on the material of the motor bracket 18, which is beneficial to reducing costs.
[0059] As a preferred embodiment of the present embodiment, the motor 13 includes a motor body 132, the motor bracket 18 includes a frame 181 that at least partially surrounds the motor body 132 and a flange portion 182 arranged on the edge of the frame 181, the flange portion 182 is provided with a screw hole, and the shell 19 is provided with a mounting hole corresponding to the screw hole, and the screw hole and the mounting hole are fastened and connected by screws.
[0060] like Figure 5 and Figure 6 As shown, by at least partially surrounding the motor body 132, the motor bracket 18 further blocks heat transfer to the motor body 132, thereby improving the thermal insulation effect. When the frame 181 is surrounded on all sides, it also facilitates sound insulation and noise reduction, thereby reducing the operating noise of the machine. The frame 181 is provided with an avoidance hole 183, through which the output shaft 131 of the motor passes to connect with the thermal insulation coupling 14.
[0061] As a preferred embodiment, the rear side of the cooking cavity 10 is provided with a mounting cavity 20 that is in communication with the cooking cavity 10. The transmission shaft 12 is provided in the mounting cavity 20. The outer side of the transmission shaft 12 is provided with a first bearing 21 and a second bearing 22 that are spaced apart. A sealing ring 23 is provided between the first bearing 21 and the second bearing 22. Figure 2 、 Figure 4 or Figure 6As shown, the driving shaft 12 is supported by a bearing to improve its working stability, and the sealing ring 23 is provided to prevent the hot air flow from escaping through the gaps between the components and causing heat loss, thereby ensuring the heating efficiency in the cooking cavity 10.
[0062] As a preferred embodiment, the side of the cooking cavity 10 is provided with an opening, and the food grilling appliance also includes a door body 24, which is rotatably arranged on the side of the cooking cavity 10 and is used to open and close the opening. The food grill 11 includes a frame body 111, a driving shaft 112 and a driven shaft 113 connected to both ends of the frame body 111, the driving shaft 112 is connected to the driving mechanism, and the side of the door body 24 facing the opening is provided with an axis hole 25 and a conical guide surface 26 formed by radially expanding and extending from the edge of the axis hole 25. The conical guide surface 26 is configured to guide the driven shaft 113 to disengage or insert into the axis hole 25 when the door body 24 is opened or closed.
[0063] like Figure 7 As shown, the food grill 11 adopts a plug-in assembly method, which is convenient for the installation, disassembly and cleaning of the food grill 11. On this basis, the door body 24 is provided with a tapered guide surface 26, which can guide the driven rotating shaft 113 to disengage and insert into the shaft hole 25, thereby promoting the smooth opening and closing of the door body 24, which is conducive to improving operating efficiency and meeting the user's quick use needs.
[0064] Specifically, the food grill 11 is mounted horizontally and can rotate about a horizontal axis. With a heating element positioned above the food grill 11, the upper and lower surfaces of the food on the grill 11 receive sufficient heat during its rotation, thereby improving the uniformity of the food heating and preventing poor browning of the food that affects the overall taste. A drive mechanism drives the food grill 11 horizontally, supporting both the front and rear ends of the food grill 11 during its rotation, improving its operational stability. Compared to conventional methods of vertically suspended rotation of the food grill 11, the food grill 11 of the present invention is more reliable and safer to use. During rotation, the driving shaft 112 is relatively fixed to the connecting member of the driving mechanism, ensuring that the rear end of the food grill 11 drives the front end of the food grill 11. The driven shaft 113 is loosely fitted with the shaft hole 25, allowing it to rotate freely, ensuring smooth rotation of the entire food grill 11. The driving shaft 112 is detachably connected to the driving mechanism, so the food grill 11 can be removed and cleaned after the machine is used, thereby improving the cleaning effect of the food grill 11. The conical guide surface 26 is in a bell-mouth shape. Under the guidance of the conical guide surface 26, the difficulty of the driven shaft 113 directly matching the shaft hole 25 is reduced, making it easier and more efficient for the user to operate the door body 24. The door body 24 is arranged to rotate, which can be as follows Figure 7The door body 24 rotates around a horizontal axis in the middle so that the opening is closed when it rotates upward and opens when it rotates downward. It can also be rotated around a vertical axis on one side of the opening to form a side-opening door. The choice is based on actual needs and is not limited in this application.
