In order to improve the heating effect of the upper heating tube of the upper body on the food, the existing improved grilling machine increases the distribution density of the heating tube segments to improve the heating effect of the upper surface of the food by the upper heating tube, so as to achieve the effect of not turning over the food. However, for such densely distributed heating tubes, the surface of the inner shell for installing the heating tubes is not easy to clean, resulting in difficulty for users to clean.

[0003] In order to facilitate users to wipe and clean the surface of the inner shell, there are some existing solutions such as patent CN 218009398 U which discloses a grilling machine, in which the heating tube is rotatably connected to the reflective plate, and the purpose of conveniently cleaning the surface of the inner shell can be achieved by flipping the heating tube.

[0004] However, in the scheme where the heating tube can be turned over, there are the following problems: the inner shell surface is usually provided with a raised structure for installing the heating tube, and the raised structure prevents the upper baking tray from being close to the heating tube, that is, there is a large gap between the heating tube and the upper baking tray, so part of the heat of the heating tube will be consumed in the gap, resulting in a reduction in the heat transferred to the upper baking tray, and reducing the heat transfer efficiency, resulting in poor heating effect of the upper baking tray on the food, and the user still needs to turn the food over to achieve the expected cooking effect, which increases the user's workload and is not conducive to improving the user experience.

[0048] like Figures 1 to 9 As shown, the present application provides a grilling machine for optimizing heating effect, comprising an upper grilling plate assembly, wherein the upper grilling plate assembly comprises an outer cover 10, an inner cover 11, a heating tube 12 arranged on the inner surface of the inner cover 11, and an upper grilling plate 13 arranged below the heating tube 12, a protrusion 14 is arranged on the inner surface of one side edge of the inner cover 11, the heating tube 12 is rotatably connected to the protrusion 14, the upper grilling plate 13 comprises a bottom wall 131 located in the middle and an extension wall 132 arranged at the edge of the bottom wall 131, the extension wall 132 extends laterally to below the protrusion 14, the bottom wall 131 and the extension wall 132 are connected by an avoidance portion 133 for avoiding the protrusion 14, so that the bottom wall 131 is located within a height range between the bottom end of the heating tube 12 and the bottom end of the protrusion 14.

[0049] Specifically, the grilling machine further includes a lower grill assembly, and the outer cover 10 can, on the one hand, play a role in heat insulation and scalding prevention, so that the user will not be scalded when touching the outer cover 10, and on the other hand, the outer cover 10 can be hingedly installed with the lower grill assembly, so that the user can open the cover by touching the outer cover 10, thereby ensuring the safety of use. Furthermore, the inner cover 11 is provided with a protrusion 14, and the side wall of the protrusion 14 is provided with a mounting hole. The heating tube 12 includes a heating section 121 and a mounting end 122 provided at the end of the heating section 121, and the mounting end 122 is rotatably connected to the mounting hole. The heating tube 12 has a first position covering the inner surface of the inner cover 11 and a second position flipped away from the inner surface of the inner cover 11. When the inner surface of the inner cover 11 needs to be cleaned, the heating tube 12 is made to reach the second position, at which time the heating tube 12 is located below the hand, which is convenient for the user to wipe the inner surface of the inner cover 11. Furthermore, in order to keep the heating tube 12 in the first position to work, the inner surface of the inner cover 11 is provided with a locking member, for example, and the end of the heating tube 12 away from the protrusion 14 is locked or unlocked with the locking member. Locking the heating tube 12 with the locking member can ensure that the heating tube 12 remains stable during operation, thereby improving its reliability. Furthermore, the upper baking tray 13 of the present application can be a conventional solid baking tray structure, or a filter structure. When a filter is used, it is provided with a plurality of micropores, and part of the heat of the heating tube 12 can act on the food through the micropores, thereby improving the heating effect of the upper baking tray assembly on the food. The upper baking tray 13 is made of a metal material with a fast heat conduction, for example. When the upper baking tray 13 of the present application is close to the heating tube 12, the heat of the heating tube 12 can be quickly transferred to the upper baking tray 13, which is conducive to optimizing the cooking effect of the upper baking tray 13 on the food.

[0050] like Figure 1 , Figure 3 , Figure 5 or Figure 8As shown, the bottom wall 131 is arranged in the middle area of ​​the upper baking tray 13, which is the area mainly corresponding to the heating tube 12. Under the design of the avoidance portion 133, the bottom wall 131 can be arranged close to the heating tube 12, that is, the height of the bottom wall 131 is ensured to be within the height range from the bottom end of the heating tube 12 to the bottom end of the protrusion 14. Within this height range, the heat of the heating tube 12 can be quickly transferred to the bottom wall 131 and then act on the food, which can ensure the heating efficiency and avoid the slow heat conduction rate and low heating efficiency caused by the bottom wall 131 being far away from the heating tube 12, which affects the cooking effect of the upper baking tray 13 on the food. Preferably, the upper surface of the bottom wall 131 can contact the heating tube 12 to further accelerate the heat conduction.

[0051] That is, the grilling machine of the present application, under the premise that the heating tube 12 is rotatably installed, can optimize the shape of the upper grilling plate 13 so that the bottom wall 131 is close to the heating tube 12, which can shorten the heat transfer path so that the heat of the heating tube 12 can be transferred to the bottom wall 131 more quickly, and reduce heat loss. Finally, the heating effect of the upper grilling plate 13 on the upper surface of the food can be optimized, so that the food does not need to be turned over.

[0052] On the premise that the bottom wall 131 is close to the heating tube 12, the extension wall 132 can extend horizontally to the bottom of the protrusion 14, so that the overall volume of the upper grill 13 will not be too small, and it is only necessary to avoid the protrusion 14 at the position of the avoidance portion 133. The extension wall 132 can increase the shielding effect on the protrusion 14, and can prevent the food from contacting the protrusion 14 upwards or oil stains from directly splashing onto the protrusion 14 during the operation of the grilling machine, thereby expanding the contact range between the upper grill 13 and the food, which is beneficial for the upper grill 13 to cook the food, and at the same time can reduce the adhesion of oil stains to the inner surface of the inner cover 11, which is beneficial for the cleaning of the inner cover 11, and can reduce the cleaning workload of the user, thereby improving the user experience. Figure 5 As shown, the raised portion 14 has a horizontal width A, and the projection of the extended wall 132 on the horizontal plane falls within the range of A, so that the edge of the upper baking tray 13 is closer to the edge of the inner cover 11, which can avoid a large gap between the upper baking tray 13 and the inner cover 11 causing heat loss from this position, that is, the heat of the heating tube 12 can be fully transferred to the upper baking tray 13 and then act on the food, ensuring efficient use of heat.

[0053] According to the different shapes of the avoidance portion 133 , the upper baking tray 13 may adopt any of the following designs to improve the cooking effect of the upper baking tray 13 on the food.

[0054] Implementation method 1:

[0055] The avoidance portion 133 is an avoidance step formed by bending downward from the bottom wall 131 , and the avoidance step includes a bending section 134 and a horizontal section 135 . The bending section 134 is connected to the bottom wall 131 , and the horizontal section 135 is connected to the extension wall 132 . The bending section 134 is located on the outer side of the heating tube 12 .

[0056] like Figure 1 and Figure 3 As shown, the avoidance step can effectively avoid the raised portion 14, so that the bottom wall 131 can be closer to the heating tube 12, and the bent section 134 is located on the outside of the heating tube 12, which is beneficial to the expansion of the area of ​​the bottom wall 131, so that the heat of the heating tube 12 can be quickly and fully transferred to the bottom wall 131 and then act on the food, which can improve the cooking effect of the upper baking tray 13 on the food.

[0057] Specifically, the height of the horizontal section 135 is lower than the bottom wall 131, and the horizontal section 135 can avoid interference with the protruding portion 14 by transitioning through the bent section 134. With respect to the specific shape of the extension wall 132, the present application can provide the following preferred embodiments.

[0058] Embodiment 1:

[0059] The extension wall 132 extends horizontally outward from the horizontal section 135 , and an end of the extension wall 132 is plugged into and matched with the inner cover 11 .

[0060] like Figure 3 and Figure 4 As shown, the extension wall 132 is a horizontal structure, which can extend horizontally to the inner wall of the inner cover 11. The upper baking tray 13 can be easily installed by plugging the end of the extension wall 132 with the inner cover 11. In this solution, the extension wall 132 is conducive to shielding the protrusion 14. Part of the heat of the heating tube 12 can act on the food through the extension wall 132. When the food at the edge expands, it can contact the extension wall 132, which can avoid the food from contacting the protrusion 14 and causing food contamination. It can also prevent oil stains, water stains, food, etc. from splashing onto the protrusion 14, causing the protrusion 14 to be difficult to clean. The user only needs to clean the upper baking tray 13. In this solution, the upper baking tray 13 is close to a sheet structure as a whole, which is lighter and convenient for disassembly and cleaning.

[0061] Specifically, the end of the extension wall 132 can be directly plugged into the inner cover 11, and the inner cover 11 is provided with a slot. Alternatively, the end of the extension wall 132 can be additionally provided with a raised insert rib 137, and the inner cover 11 is provided with a plug hole to meet the plug connection.

[0062] Embodiment 2:

[0063] The extension wall 132 includes a flange 136 folded downward from an end of the horizontal section 135 , and the flange 136 extends along the vertical inner wall of the inner cover 11 .

[0064] like Figure 1 and Figure 2 As shown, by setting the flange 136, the upper baking tray 13 forms a hood-like structure, which can increase the contact area with the food, and when the upper baking tray assembly is matched with the lower baking tray assembly, the flange 136 is conducive to cooperating with the lower baking tray to strengthen the sealing effect of the cooking cavity, which can reduce heat loss and reduce the overflow of steam from the cooking cavity that causes the food to be too dry, which is beneficial to improving the heating efficiency and the moisturizing effect of the food.

[0065] In order to reduce heat loss as much as possible, the flange 136 can be arranged in close contact with the inner wall of the inner cover 11, so that the heat loss from the gap between the flange 136 and the inner cover 11 can be reduced, so that the heat of the heating pipe 12 can be fully transferred to the upper grill plate 13. It can be understood that the extension wall 132 can only include the flange 136, or the extension wall 132 includes the flange 136 and the horizontal extension section, and the horizontal extension section is used for the transition between the horizontal section 135 and the flange 136.

[0066] Implementation method 2:

[0067] The avoidance portion 133 is configured as a rounded corner, and the extension wall 132 includes a flange 136 disposed below the avoidance portion 133 , and the flange 136 is smoothly connected to the bottom wall 131 via a rounded corner.

[0068] like Figure 5 and Figure 6 As shown, rounded corners are used to avoid the problem, the structure is simple, and the flange 136 and the bottom wall 131 can have a smooth transition, which is conducive to cleaning the upper baking tray 13 and can avoid forming a cleaning dead corner at the turning point, ensuring that the upper baking tray 13 is clean and hygienic.

[0069] In this embodiment, the bottom wall 131 is expanded, and the uniformity of heating the food by the bottom wall 131 can be improved. In addition, the rounded corners can increase the contact area with the food, which is conducive to enhancing the contact frying effect of the upper baking tray 13 on the food.

[0070] Implementation method three:

[0071] The avoidance portion 133 is arranged at an oblique angle, and the extension wall 132 includes a flange 136 arranged below the avoidance portion 133 , and the flange 136 is connected to the bottom wall 131 at an oblique angle.

[0072] like Figure 8 and Fig. 9As shown, the oblique angle avoidance is adopted, the structure is simple, and it is conducive to maximizing the volume of the upper baking tray 13, so as to improve the wrapping effect of the upper baking tray 13 on the food, and finally improve the cooking effect of the food. Specifically, the bottom wall 131 is a horizontal structure, the extension wall 132 is a vertical structure, and the avoidance portion 133 adopts an inclined surface structure to achieve the transition between the bottom wall 131 and the extension wall 132.

[0073] In this embodiment, the bottom wall 131 is expanded, and the uniformity of heating the food by the bottom wall 131 can be improved. In addition, the inclined surface of the avoidance portion 133 can increase the contact area with the food, which is conducive to enhancing the contact frying effect of the upper grilling plate 13 on the food.

[0074] In the above embodiment where the extension wall 132 includes the flange 136, further, as Figure 1 , Figure 5 or Figure 8 As shown, the flange 136 extends along the vertical inner wall of the inner cover 11 and protrudes out of the inner cover 11 .

[0075] The setting of the flange 136 can increase the contact between the food and the upper baking tray 13 in the vertical area, and the longer setting of the flange 136 can enhance the wrapping effect on the food. When the flange 136 cooperates with the lower baking tray, it is beneficial to the sealing of the cooking cavity, which can reduce heat and steam loss, and ultimately improve the cooking quality of the food.

[0076] Furthermore, the grilling machine further comprises a lower grilling pan assembly, and when the upper grilling pan assembly covers the lower grilling pan assembly, the lower end of the flange 136 is inserted into the lower grilling pan assembly.

[0077] The longer flange 136 can act as a stop when inserted into the lower baking tray assembly, which is beneficial to the sealing of the cooking cavity, reduces heat and steam loss, and ultimately improves the cooking quality of food.

[0078] Furthermore, to facilitate the installation of the upper baking tray 13 and the inner cover 11, the outer wall of the flange 136 is provided with a rib 137, and the inner cover 11 is provided with a plug hole, so that the upper baking tray 13 and the inner cover 11 can be plugged and fixed. Alternatively, the flange 136 can be provided with a plug hole, and the inner cover 11 can be provided with a rib, so that the upper baking tray 13 and the inner cover 11 can be plugged and fixed.

[0079] As a preferred embodiment of the present application, the projection of the heating tube 12 on the horizontal plane falls within the range of the projection of the bottom wall 131 on the horizontal plane.

The movable buckle 16 is rotatably arranged to have a first state of locking cooperation with the fixed buckle 15 and a second state of unlocking with the fixed buckle 15; the other end of the upper baking tray 13 is plugged into and cooperated with the inner cover 11.

[0082] like Figure 1 , Figure 3 , Figure 5 or Figure 8 As shown, a detachable component is provided between the inner cover 11 and the outer cover 10, and the detachable component includes an active buckle 16 and a button 17. One end of the button 17 is exposed from the outer cover 10, and the other end of the button 17 is connected to the active buckle 16 to drive the active buckle 16. The active buckle 16 can rotate to have a first position and a second position. When the active buckle 16 is in the first position, the active buckle 16 is locked with the fixed buckle 15. When the active buckle 16 is in the second position, the active buckle 16 is separated from the fixed buckle 15.

[0083] The upper baking tray 13 is detachable, which is convenient for the user to remove the upper baking tray 13 for cleaning. The user can remove the upper baking tray 13 by pressing the button 17, which is easy to operate. When the movable buckle 16 is in the first position, the movable buckle 16 is locked with the fixed buckle 15. When the upper baking tray 13 needs to be removed, the user can press the button 17, and the movable buckle 16 is pressed and tilted, so that the movable buckle 16 can be moved away from the fixed buckle 15, and the movable buckle 16 is switched to the second position. Then, the fixed buckle 15 unlocks the upper baking tray 13 and the upper baking tray 13 can be easily removed.

[0084] Furthermore, a rib 137 is provided on one of the end of the upper baking tray 13 away from the fixing buckle 15 and the inner cover 11, and a socket is provided on the other end thereof, and the rib 137 is plugged into and matched with the socket.

[0085] Specifically, Figure 4 , Figure 5 or Figure 6As shown, one end of the upper baking tray 13 is provided with a fixed buckle 15, and the other end is provided with two spaced inserts 137. When installing the upper baking tray 13, first insert the two inserts 137 into the two plug holes of the inner cover 11, and then lock the fixed buckle 15 with the movable buckle 16 to complete the installation of the upper baking tray 13. In this way, both ends of the upper baking tray 13 are limited, which can ensure the stability of the upper baking tray 13 during use. Among them, the plug hole can be a through hole or a blind hole, which is not limited in this application. In other embodiments, the setting positions of the insert 137 and the plug hole can be replaced, that is, the insert 137 is provided on the inner cover 11, and the plug hole is provided on the upper baking tray 13.
