As shown in fig. 1, an embodiment of the present application provides a cooking apparatus 100, where the cooking apparatus 100 includes: a case 110, a tray 120, and a driving mechanism 130.

The box body 110 has an accommodating space 113 therein, and the accommodating space 113 is used for accommodating food to cook the food. Wherein, the accommodating space 113 can be closed during the cooking process, i.e. the box body 110 is sealed; the receiving space 113 may also be open during cooking, i.e., the cabinet 110 is open. Regardless of whether the accommodating space 113 is open or not, the accommodating space 113 is adjacent to all or part of the inner surface of the case 110, and all or part of the inner surface of the case 110 serves as a wall surface surrounding the accommodating space 113.

Specifically, the cooking apparatus may include various cooking manners, for example, cooking food may be performed in a baking manner, in which case, the cooking apparatus 100 is an oven; the food can be cooked by steaming, in which case the cooking device 100 is a steam box; the food can be cooked by electromagnetic heating, in which case the cooking device 100 is an induction cooker; the food may be cooked by baking or steaming, and the cooking apparatus 100 is a steaming oven. Those skilled in the art should understand that the cooking device of the present application specifically uses a cooking method, cooks specific food, and applies specific cooking environment (household or commercial, etc.) without limitation to the protection scheme of the cooking device of the present application. In the embodiment of the present application, the cooking apparatus 100 is taken as an example of an oven for description.

As shown in fig. 1, the inner surface of the case 110 adjacent to the receiving space 113 is formed with a guide groove 111 extending in a first direction. The first direction may be a vertical direction, a horizontal direction, or an inclined direction having an included angle with both the vertical direction and the horizontal direction. The guide groove 111 may be a concave groove formed by recessing the inner surface of the case 110 in a direction away from the accommodating space 113, or may be a concave groove formed on a protrusion formed on the inner surface of the case 110 in a direction close to the accommodating space 113, and the following description will be given by using the guide groove 111 as a concave groove formed on the inner surface of the case 110.

As shown in fig. 2, a tray 120 is provided in the receiving space 113 for receiving food. Specifically, the tray may be a solid member without an opening, or may be a member with an opening or a net shape; the tray 120 may be substantially flat and the tray 120 may have a first side wall adjacent to the guide groove 111, and it should be noted that the adjacent means may be that the tray 120 is in contact with the first side wall, or may have a small gap without other components in the gap. The first sidewall is provided with a first protrusion 121, and the first protrusion 121 is coupled to the guide groove 111 to guide the tray 120 to move in the first direction. Specifically, the first protrusion 121 may be partially located in the guide groove 111, or may be entirely located in the guide groove 111, and as long as at least a part of the first protrusion 121 is always located in the guide groove 111 in the operation movement stroke, the movement direction of the first protrusion 121, and thus the movement direction of the tray 120, may be guided by using the guide groove 111. When the first direction is a vertical direction, the tray 120 is guided by the guide groove 111 to move in the vertical direction, and when the first direction is another direction, the tray 120 may move in another direction.

As shown in fig. 2, the driving mechanism 130 is connected to the tray 120 and is used for driving the tray 120 to move along a first direction, so that the food position in the tray can be adjusted in the baking process, and the cooking effect is improved. In addition, the driving mechanism 130 is disposed in the accommodating space 113, so that the accommodating space 113 in the box body is fully utilized, the structure outside the box body is not additionally increased, the structure is simplified, and the appearance of the cooking device is attractive.

As shown in fig. 3, in the case that the first direction is a vertical direction (e.g., a vertical direction in fig. 3), for example, in the case that a heating mechanism such as an electric heating tube for supplying heat to the inside of the oven is disposed at the top of the accommodating space, the higher the height of the tray 120 is, the closer to the heating mechanism is, so that the heating temperature of the food can be increased by increasing the height of the tray 120, and the heating temperature of the food can be decreased by decreasing the height of the tray 120. In the process of cooking food, the heating temperature of the food can be adjusted by adjusting the height of the tray 120 to adapt to the cooking requirements of different foods and improve the cooking effect of the food. The following description will be given taking a case where the first direction is a vertical direction as an example.

As shown in fig. 3, in some embodiments of the present application, a plurality of trays 120 may be provided, and different foods may be respectively placed on the plurality of trays 120, so as to meet the requirement of cooking multiple foods simultaneously. The plurality of trays 120 may be stacked in a first direction (i.e., a vertical direction) (as shown in fig. 3), i.e., the plurality of trays 120 are respectively disposed at different heights. Of course, the plurality of trays 120 may also be distributed at intervals in the horizontal direction (as shown in fig. 4), that is, the plurality of trays 120 are respectively disposed at different positions in the horizontal direction, and the movement of each tray 120 in the vertical direction is not interfered by other trays 120. No matter which kind of setting mode, all can place different food in the height of difference toasts, and the heating temperature that is located the food that holds in the tray 120 of upper strata is greater than the heating temperature that is located the food that holds in the tray 120 of lower floor, can satisfy different food and toast the different demands of in-process to the temperature.

As shown in fig. 3 and 4, in some embodiments of the present application, the driving mechanism 130 may be provided in plural, and there is a one-to-one correspondence between the driving mechanisms 130 and the trays 120, that is, each driving mechanism 130 is fixedly connected to one corresponding tray 120. By controlling each tray 120 corresponding to each driving mechanism 130 separately, the position of each tray 120 in the vertical direction can be adjusted. For example, in the case where the trays 120 are two and stacked (as shown in fig. 3), the upper tray 120 can be adjusted to different heights between the lower tray 120 and the top of the accommodating space by controlling the driving mechanism 130 connected to the upper tray 120; the lower tray 120 can be adjusted to different heights between the upper tray 120 and the bottom of the receiving space by controlling the driving mechanism 130 connected to the lower tray 120. For example, in the case where the trays 120 are three and stacked, the upper tray 120 can be adjusted to different heights between the middle tray 120 and the top of the accommodating space by controlling the driving mechanism 130 connected to the upper tray 120; the different heights of the middle tray 120 between the upper tray 120 and the lower tray 120 can be adjusted by controlling the driving mechanism 130 connected to the middle tray 120; the lower tray 120 can be adjusted to different heights between the middle tray 120 and the bottom of the receiving space by controlling the driving mechanism 130 connected to the lower tray 120. For example, in the case that the trays 120 are plural and are spaced apart in the horizontal direction (as shown in fig. 4), each driving mechanism 130 can adjust each tray 120 to be at a different height between the top of the accommodating space and the bottom of the accommodating space by controlling the tray 120 corresponding thereto.

In other embodiments of the present application, there may be only one driving mechanism, in which case, the plurality of trays may each be fixedly connected to the driving mechanism, i.e. one driving mechanism adjusts the plurality of trays simultaneously. The driving mechanism can synchronously increase the heights of all the trays so as to synchronously increase the heating temperature of the food in all the trays; or the heights of all the trays are reduced synchronously so as to reduce the heating temperature of the food contained in all the trays synchronously.

In the case that the first direction is a horizontal direction (e.g., a left-right direction in fig. 5), for example, in the case that a heating mechanism such as an electric heating tube for supplying heat to the oven is disposed at the left side of the accommodating space 113, the closer the tray 120 is to the left side in the horizontal direction, the closer the tray 120 is to the heating mechanism, so that the heating temperature of the food can be increased by moving the tray 120 to the left, and the heating temperature of the food can be decreased by moving the tray 120 to the right. In the process of cooking food, the heating temperature of the food can be adjusted by adjusting the movement of the tray 120 in the horizontal direction, so as to adapt to the cooking requirements of different foods and improve the cooking effect of the food. The following description will be given taking a case where the first direction is a horizontal direction (i.e., a left-right direction in fig. 5) as an example.

As shown in fig. 5, in other embodiments of the present application, a plurality of trays 120 may be provided, and different foods may be respectively placed on the plurality of trays 120, so as to meet the requirement of cooking multiple foods simultaneously. The trays 120 may be stacked in a vertical direction (i.e., a vertical direction) of the first direction (as shown in fig. 5), that is, the trays 120 are respectively disposed at different heights, different foods may be placed at different heights for baking, the trays 120 do not interfere with each other when moving in a horizontal direction, and the positions of the trays 120 in the horizontal direction may not be completely the same. Of course, the plurality of trays 120 may be disposed in the same horizontal plane (as shown in fig. 6), and the plurality of trays 120 may be sequentially distributed in the left-right direction. The position of partial tray 120 can be close to the left side, and the position of partial tray 120 can be close to the right side, and the heating temperature that is located the food that holds in the tray 120 on left is greater than the heating temperature that is located the food that holds in the tray 120 on right, can satisfy different food and toast the different demands of in-process to the temperature.

In other embodiments of the present application, as shown in fig. 5, the driving mechanism 130 may be provided in plural, and there is a one-to-one correspondence between the driving mechanisms 130 and the trays 120, i.e., each driving mechanism 130 is fixedly connected to one corresponding tray 120. By controlling each tray 120 corresponding to each driving mechanism 130 separately, the position of each tray 120 in the horizontal direction can be adjusted. For example, in the case where the trays 120 are two and located at the same horizontal plane (as shown in fig. 6), the left tray 120 can be adjusted to different positions between the right tray 120 and the left side of the accommodating space 113 by controlling the driving mechanism 130 connected to the left tray 120; the right tray 120 can be adjusted to different positions between the left tray 120 and the right side of the receiving space 113 by controlling the driving mechanism 130 connected to the right tray 120. For example, in the case where the trays 120 are three and located at the same level, the left tray 120 can be adjusted to different positions between the middle tray 120 and the left side of the accommodating space 113 by controlling the driving mechanism 130 connected to the left tray 120; the intermediate tray 120 can be adjusted to different positions between the left side tray 120 and the right side tray 120 by controlling the driving mechanism 130 connected to the intermediate tray 120; the right tray 120 can be adjusted to different positions between the middle tray 120 and the right side of the receiving space 113 by controlling the driving mechanism 130 connected to the right tray 120. For example, in the case where the trays 120 are stacked (as shown in fig. 5), each of the driving mechanisms 130 can adjust each of the trays 120 to be located at different positions between the left side of the accommodating space 113 and the right side of the accommodating space 113 by controlling the tray 120 corresponding thereto.

In other embodiments of the present application, there may be only one driving mechanism, in which case, the plurality of trays may each be fixedly connected to the driving mechanism, i.e. one driving mechanism adjusts the plurality of trays simultaneously. The driving mechanism can synchronously move all the trays to the left side so as to synchronously improve the heating temperature of the food in all the trays; or all the trays are moved to the right simultaneously to reduce the heating temperature of the food contained in all the trays simultaneously.

In the case that the first direction is an inclined direction (e.g., X direction in fig. 7), for example, in the case that a heating mechanism such as an electric heating tube for providing heat to the oven is disposed at the upper left corner of the accommodating space 113, the closer the tray 120 is to the heating mechanism in the inclined direction, the higher the temperature of the food can be heated by moving the adjusting tray 120 to the upper left corner, and the lower the temperature of the food can be heated by moving the adjusting tray 120 to the lower right corner. In the process of cooking food, the heating temperature of the food can be adjusted by adjusting the movement of the tray 120 in the inclined direction, so as to adapt to the cooking requirements of different foods and improve the cooking effect of the food.

As shown in fig. 7, in other embodiments of the present application, a plurality of trays 120 may be provided, and different foods may be respectively placed on the plurality of trays 120, so as to meet the requirement of cooking multiple foods simultaneously. The trays 120 may be stacked in a first direction (as shown in fig. 7), that is, the trays 120 are disposed at different positions in the first direction, and the moving directions of the trays 120 are overlapped, so that different foods can be placed at different positions in the first direction for baking. Of course, the trays 120 may be spaced apart from each other in a direction perpendicular to the first direction (e.g., Y direction in fig. 8) (as shown in fig. 8), that is, the moving directions of the trays 120 are parallel to each other, so that different foods can be placed at different positions in the oblique direction for baking, and the trays 120 do not interfere with each other when moving in the oblique direction. The position of partial tray 120 can be close to the upper left corner, and the position of partial tray 120 can be close to the lower right corner, and the heating temperature that is located the food that holds in the tray 120 in the upper left corner is greater than the heating temperature that is located the food that holds in the tray 120 in the lower right corner, can satisfy different food to the different demands of temperature in the baking process.

In other embodiments of the present application, as shown in fig. 7, the driving mechanism 130 may be provided in plural, and there is a one-to-one correspondence between the driving mechanisms 130 and the trays 120, i.e., each driving mechanism 130 is fixedly connected to one corresponding tray 120. By controlling each tray 120 corresponding thereto by each driving mechanism 130, the position of each tray 120 in the tilt direction can be adjusted. For example, in the case that two trays 120 are stacked in the first direction (as shown in fig. 8), the upper left tray 120 can be adjusted to different positions between the lower right tray 120 and the upper left corner of the accommodating space 113 by controlling the driving mechanism 130 connected to the upper left tray 120; the lower right tray 120 can be adjusted to different positions between the upper left tray 120 and the lower right corner of the accommodating space 113 by controlling the driving mechanism 130 connected to the lower right tray 120. For example, in the case that three trays 120 are stacked in the first direction, the upper left tray 120 can be adjusted to different positions between the middle tray 120 and the upper left corner of the accommodating space 113 by controlling the driving mechanism 130 connected to the upper left tray 120; the middle tray 120 can be adjusted to be positioned at different positions between the upper left tray 120 and the lower right tray 120 by controlling the driving mechanism 130 connected to the middle tray 120; the lower right tray 120 can be adjusted to different positions between the middle tray 120 and the lower right corner of the receiving space 113 by controlling a driving mechanism 130 connected to the lower right tray 120. For example, in the case that the trays 120 are plural and are spaced apart in the vertical direction of the first direction (as shown in fig. 7), each of the driving mechanisms 130 can adjust each of the trays 120 to a different position between the lower left corner of the accommodating space 113 and the upper right corner of the accommodating space 113 by controlling the tray 120 corresponding thereto.

In other embodiments of the present application, there may be only one driving mechanism, in which case, the plurality of trays may each be fixedly connected to the driving mechanism, i.e. one driving mechanism adjusts the plurality of trays simultaneously. The driving mechanism can synchronously move all the trays to the upper left corner so as to synchronously increase the heating temperature of the food in all the trays; or all the trays are synchronously moved to the lower right corner so as to synchronously reduce the heating temperature of the food contained in all the trays.

As shown in fig. 1 and 2, in some embodiments of the present application, the guide groove 111 is spaced at intervals on the inner surface, and the plurality of guide grooves 111 may be spaced at intervals in a direction perpendicular to the first direction, that is, the guide directions of the plurality of guide grooves 111 are parallel to each other. Each tray 120 has a first protrusion 121, and a plurality of first protrusions 121 are in one-to-one correspondence with the plurality of guide grooves 111. Each first protrusion 121 is at least partially located in the corresponding guide groove 111 to move in the guide direction of the corresponding guide groove 111. Specifically, the guide groove 111 may be formed by the inner wall of the box body 110 attached to the accommodating space 113 and being recessed toward a direction away from the accommodating space 113, so that there is no gap between the guide groove 111 and the box body 110, which is beneficial for a user to clean the inside of the box body 110. The portion of the first protrusion 121 located in the guide groove 111 may abut against the sidewall of the guide groove 111 when moving in the direction deviating from the guiding direction of the guide groove 111, and cannot move further in the direction deviating from the guiding direction of the guide groove 111, which is the first direction, so that the first protrusion 121 may move only in the opposite direction of the first direction and the first direction.

As shown in fig. 9, in some embodiments of the present application, the driving mechanism 130 extends along a first direction, and during operation, the portion of the driving mechanism 130 for connecting to the corresponding tray 120 moves along the first direction, so as to drive the corresponding tray 120 to move along the first direction. The driving mechanism 130 and the guide groove 111 are oppositely arranged on two opposite sides of the tray 120, the guide groove 111 can limit the freedom degree of the tray 120 to rotate on a plane perpendicular to the first direction, the driving mechanism 130 can limit the freedom degree of the tray 120 to translate on the plane, and the moving direction of the tray 120 is limited to the first direction under the combined action of the driving mechanism 130 and the guide groove 111. Moreover, because the surface of the tray 120 adjacent to the guide groove 111 can be a plane, under the condition that the plane is attached to the guide groove 111, the degree of freedom of rotation of the tray 120 in a vertical plane is also limited, when food is loaded on the tray 120, the pressure applied by the food to the tray 120 can cause one end of the tray 120 fixedly connected to the driving mechanism 130 to bear bending moment, and the guide groove 111 can bear partial bending moment at the other end of the tray 120, so that the bending moment borne by the driving mechanism 130 can be effectively reduced, and the working stability of the driving mechanism 130 and the tray 120 can be improved.

As shown in fig. 9, in some embodiments of the present application, the driving mechanism 130 may include: a linear stepping motor 133, a lead screw 131 and a nut 132, wherein the linear stepping motor 133 is an electromechanical element that converts an electrical pulse signal into an angular displacement or a linear displacement. The input quantity of the linear stepping motor 133 is a pulse sequence, the output quantity is corresponding incremental displacement and stepping motion, and the output shaft of the linear stepping motor 133 can be fixedly connected to the screw rod 131 to drive the screw rod 131 to rotate, or can be in transmission connection with the screw rod 131 through other transmission modes such as gear transmission, key transmission and the like to drive the screw rod 131 to rotate and control the screw rod 131 to stop rotating. The screw 131 extends in a first direction, i.e. the axis of the screw 131 is the first direction. The nut 132 is disposed on the lead screw 131 and screwed to the lead screw 131, and when the lead screw 131 rotates relative to the nut 132, the nut 132 moves relative to the lead screw 131 in a first direction. The nut 132 is fixedly connected to the tray 120, because the tray 120 can only move along the first direction and cannot rotate around the first direction, the nut 132 cannot rotate around the first direction, the linear stepping motor 133 controls the rotation amount of the lead screw 131, namely the rotation amount of the lead screw 131 relative to the nut 132, and the accurate control of the rotation angle through the linear stepping motor 133 can realize the accurate control of the movement amount of the nut 132 in the first direction, so that the movement amount of the tray 120 in the first direction can be accurately controlled.

As shown in fig. 2 and 9, in some embodiments of the present application, a second protrusion 122 is disposed on a second side wall of the tray 120 opposite to the first side wall, and the second protrusion 122 is adjacent to and fixedly connected to the nut 132. The nut 132 drives the tray 120 to move along the first direction through the second protrusion 122, and because the nut 132 can be tightly attached to the screw rod 131, the axial direction of the tray 120 can be kept as the first direction under the condition of bearing the bending moment applied to the tray 120, and the stability of the movement process of the tray 120 is ensured.
