[0030] The heating methods of components such as graphite heating sheets are different from those of metal tubes and quartz tubes. Metal tubes, quartz tubes, etc. generally radiate heat evenly towards their surroundings, while graphite heating sheets, etc., due to being sheet-shaped, do not have uniform thermal radiation. The thermal radiation in the vertical direction of the heating sheet is stronger than in other directions. For this reason, the present invention provides a technical solution to make full use of the heat of the graphite heating plate. By adjusting the angle of the graphite heating sheet, the direction of thermal radiation can be made adjustable, so as to achieve the best food cooking curve.

[0031] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0032] Combined with Figures 1 to 6 , the cooking device 100 according to an embodiment of the present invention includes: a box body, a position detector 20, and a heating element 30. Among them, the box body serves as the main body of the cooking device 100 and can be used as a storage device for accommodating items to be cooked (such as items to be thawed, grilled, etc.) to provide a storage space for the items to be cooked. The position detector 20 can detect the position of the item to be cooked for timely feedback. The heating element 30 can heat the item to be cooked to achieve cooking of the item to be cooked.

[0033] Specifically, a cooking cavity 101 is provided in the box body. The cooking cavity 101 can be used to accommodate items to be cooked. For example, the item to be cooked can be directly placed into the cooking cavity 101, or the item to be cooked can be placed into the cooking cavity 101 through a container.

[0034] The position detector 20 is connected to the box body. The position detector 20 is configured to be suitable for detecting the position of the item to be cooked in the cooking cavity 101. Through the position detector 20, the position of the item to be cooked placed in the cooking cavity 101 can be obtained, so that the cooking device 100 can timely detect the item and provide it to the heating element 30, thereby facilitating the heating element 30 to radiate heat.

[0035] The heating element 30 is movably arranged on the box body. The heating element 30 is in signal transmission with the position detector 20. The heating element 30 is configured to be suitable for adjusting its position according to the position of the item to be cooked. That is to say, when the position detector 20 obtains the position of the item to be cooked, the best cooking effect can be achieved by moving the heating element 30. For example, centralized heating of the item to be cooked can be realized to improve the heating efficiency; the item to be cooked can be heated with a more appropriate power to obtain a better taste, etc.

[0036] In the cooking device 100 according to the embodiment of the present invention, the position detector 20 and the heating element 30 with a movable position are provided. Through the detection of the position of the item to be cooked by the position detector 20, the storage device of the item can be timely detected, and the position of the heating element 30 is adjustable and there is signal transmission between the heating element 30 and the position detector 20, so that the position of the heating element can be adjusted according to the storage position of the item to be cooked, thereby realizing the required heat radiation for the item to be cooked, effectively improving the cooking effect, and improving the taste of the cooked food, etc.

[0037] For heating elements 30 such as metal tubes and quartz tubes, the heating effect of the heating element 30 on the food can be adjusted by adjusting the distance between the heating element 30 and the food, etc. For heating elements 30 such as graphite tubes, the heating effect of the heating element 30 on the food can be adjusted by adjusting the distance between the heating element 30 and the food and adjusting the angle of the heating element 30. In the present invention, the adjustment method of the heating element 30 in the present invention is mainly illustrated by taking the heating element 30 with different heat radiations in each direction as an example, but this is not a limitation on the protection scope of the present invention.

[0038] Combined with Figure 7It can be seen that in some embodiments of the present invention, the heating element 30 includes a plurality of radiation surfaces, and the plurality of radiation surfaces can have different thermal radiation powers. That is to say, the heating element 30 has a plurality of radiation surfaces, and there are differences in the thermal radiation powers of these radiation surfaces. The heating element 30 is configured to be adapted to adjust the heating area of the plurality of radiation surfaces by moving. During actual use, generally, the radiation surface with a larger thermal radiation power needs to be oriented towards the food to be cooked. Therefore, during the cooking process, after the position detection element 20 obtains the position of the food, the position of the heating element 30 can be adjusted to face the radiation surface with a larger thermal radiation power in the heating element 30 towards the food to be cooked, so as to obtain a better cooking effect, improve the utilization rate of energy, and save energy and protect the environment. Of course, according to different cooking purposes, it may also be necessary to face the radiation surface with a smaller thermal radiation power or a moderately smaller thermal radiation power in the heating element 30 towards the food to be cooked. In the present invention, by distinguishing the thermal radiation surfaces of the heating element 30, the cooking effect can be effectively improved, making the cooking process more user-friendly and controllable, etc., fully meeting the daily cooking needs.

[0039] Among them, as Figure 7 shown, in an embodiment of the present invention, the heating element 30 is a graphite tube, and the thermal radiation powers of the graphite tube in all directions are different, and the distribution of the strength of its thermal radiation power is as shown in the figure. Therefore, through the technical solution of the embodiment of the present invention, by rotating the heating element 30, the adjustment of the thermal radiation power of the food can be achieved. In addition, Figure 8 shows the thermal radiation condition of a quartz tube, and its radiation powers in all directions are basically the same.

[0040] As mentioned above, the heating element 30 in the present invention can be position-adjusted by means of translation, rotation, etc. As shown in the figure, in some embodiments of the present invention, the heating element 30 is rotatably connected to the box body, and a plurality of radiation surfaces are arranged around the rotation center axis of the heating element 30, so that by rotating the heating element 30, the corresponding relationship between the plurality of radiation surfaces on the heating element 30 and the food to be cooked can be adjusted, improving the cooking effect. By setting the heating element 30 in a rotatable form, the moving mode of the heating element 30 can be simplified, and the driving structure of the heating element 30 can be simplified, facilitating the control of the movement of the heating element 30.

[0041] Optionally, as Figure 1 shown, the box body includes a first side wall 11 and a second side wall 12, the first side wall 11 and the second side wall 12 are oppositely arranged, one end of the heating element 30 is rotatably connected to the first side wall 11 and the other end is rotatably connected to the second side wall 12. By rotatably supporting the heating element 30 on the box body, the structure of the cooking device 100 is simplified, and the performance of the cooking device 100 is optimized. In addition, the box body may further include a top wall, a bottom wall 13 and a back plate, and a cooking cavity 101 with an open front side is enclosed by the top wall, the bottom wall 13, the back plate, the first side wall 11 and the second side wall 12.

[0042] Of course, other structures can also be provided in the present invention to install the heating element 30. For example, a support member can be provided on the top wall, and the heating element 30 can be installed on the top wall of the cooking cavity 101 through the support member. The two ends of the heating element 30 can be directly installed on the first side wall 11 and the second side wall 12, or a support structure can be provided on the first side wall 11 and / or the second side wall 12 to install the heating element 30 through the support structure.

[0043] In addition, the heating element 30 can also be installed on adjacent side walls of the box body, such as connecting the two ends of the heating element 30 to the first side wall 11 and the back plate, the first side wall 11 and the top wall, etc. Of course, the heating element 30 can also be set in a cantilever shape.

[0044] Such as Figure 1 , in some embodiments of the present invention, a rotating motor 50 is provided on the box body, and the rotating motor 50 is connected to the heating element 30 to drive the heating element 30 to rotate. By providing the rotating motor 50 to drive the heating element 30 to rotate, the driving structure of the heating element 30 can be effectively simplified.

[0045] In addition, the heating element 30 in the present invention can be one, and the heating element 30 can also be at least two arranged at intervals. When the heating element 30 is at least two arranged at intervals, a single rotating motor 50 can be used to drive multiple heating elements 30 to rotate, or a rotating motor 50 can be provided corresponding to each heating element 30 for driving. For example, a rotating structure is provided, and power is transmitted to different heating elements 30 through a predetermined transmission method, and the rotation angles, rotation speeds, etc. of different heating elements 30 can be designed to be different.

[0046] Such as Figure 1 , in some embodiments of the present invention, the heating element 30 is configured as a long strip-shaped rod. Thereby, the structure of the heating element 30 can be simplified, which is convenient for heating the food to be cooked. The long strip-shaped heating element 30 can be a long strip extending in a straight line direction, or a long strip extending in a curve, a wavy line, etc. Of course, the heating element 30 in the present invention can also be disk-shaped or other shapes.

[0047] In some examples of the present invention, the heating element 30 is provided at the top inside the cooking cavity 101. Thereby, the heating radiation range of the heating element 30 can be increased, the heating range can be increased, and the heating of a specific area can be realized by adjusting the heating element 30, improving the heating effect.

[0048] In addition, in combination with the foregoing description, the heating element 30 in the present invention can be configured as a graphite tube. The heating element 30 can include a graphite heating sheet 31 and an outer tube 32. The graphite heating sheet 31 is disposed inside the outer tube 32. The surfaces of the outer tube 32 corresponding to the non-connecting positions of the graphite heating sheet 31 can be respectively configured as non-connecting heat radiation surfaces. Among them, the surface of the outer tube 32 facing the graphite heating sheet 31 in the normal direction is a heat radiation surface with a relatively high heat radiation power; the surface of the outer tube 32 facing the side of the graphite heating sheet 31 can be a heat radiation surface with a relatively low heat radiation power; and the surface of the outer tube 32 obliquely facing the surface of the graphite heating sheet 31 can be a heat radiation surface with a medium heat radiation power.

[0049] In the present invention, the position of the food can be obtained in different ways. For example, the position detecting member 20 can be set as a control button, a touch screen, etc., and the position of the food to be cooked can be detected by direct input. In addition, the position detecting member 20 can also be set as a camera, a sensor, etc., and the storage position of the food to be cooked in the cooking cavity 101 can be automatically obtained by detection, analysis, etc. For example, an image in the cooking cavity 101 can be captured by a camera, and the position of the food to be cooked can be obtained through image processing.

[0050] In some embodiments of the present invention, the position detecting member 20 includes a sensor and / or an infrared camera. The position detecting member 20 is disposed outside the cooking cavity 101 and faces the inside of the cooking cavity 101. By disposing the position detecting member 20 to face the inside of the cooking cavity 101, the automatic acquisition of the position of the food to be cooked in the cooking cavity 101 can be realized, the control mode of the cooking device 100 is optimized, the cooking device 100 is made more intelligent and easy to operate, and the position of the heating element 30 can be adjusted quickly and stably.

[0051] Optionally, as Figure 1 and Figure 3 , the position detecting member 20 is disposed in the middle or upper part of the side wall of the cooking cavity 101. Thereby, the position detecting member 20 can be placed at a relatively high position, so that the detection range of the position detecting member 20 can cover a larger area, and the detection range of the position of the food to be cooked is improved.

[0052] In some embodiments of the present invention, the position detecting member 20 includes one. In addition, the position detecting member 20 can include a plurality. By providing a plurality of position detecting members 20, while effectively improving the detection range of the position detecting member 20, the detection accuracy of the position can be improved, so as to more conveniently and accurately control the cooking device 100, and effectively improve the intelligence of the cooking device 100 to be cooked.

[0053] As Figure 1As shown, in some embodiments of the present invention, a cooking utensil 40 is provided in the cooking cavity 101, and the position detector 20 is configured to have a detection range covering the cooking utensil 40. Of course, the utensil in the cooking cavity 101 can also be an optional part, and the detection range of the position detector 20 can include all the spaces below the horizontal plane at a predetermined height.

[0054] In addition, according to different actual cooking requirements, in addition to detecting the horizontal position of the item to be cooked, it may also be necessary to detect the height, etc. of the item to be cooked. For example, the heating element 30 in the present invention can be provided at other positions in the cooking cavity 101 to heat the food to be cooked from the side of the cooking cavity 101 and so on. By performing an all-round position detection of the item to be cooked, a better heating effect can be provided.

[0055] Optionally, as Figure 2 shown, a part of the side wall of the cooking cavity 101 bulges towards the inside of the cooking cavity 101 to form a boss 15, and the probe of the position detector 20 extends into the boss 15. Among them, an opening can be provided on the bottom wall 13 of the boss 15, and the probe of the position detector 20 is directed towards the opening, where the opening can be empty or closed and is suitable for the probe to perform detection. Thereby, the detection accuracy can be improved.

[0056] Optionally, as Figure 2 shown, a mounting bracket 14 is provided outside the side wall of the cooking cavity 101, and the position detector 20 is mounted on the mounting bracket 14. Thereby, the installation of the position detector 20 is facilitated, the stability of the position detector 20 is improved, and the overall structure of the cooking device 100 is optimized.

[0057] The present invention relates to a cooking appliance that can automatically identify the position of food and the heating tube adjusts its angle according to the position of the food. By adjusting the angle of the graphite heating sheet 31, the direction of heat radiation can be made adjustable, so as to achieve the best food cooking curve. The position detector 20 of the present invention can be an infrared camera, and the infrared camera can identify and judge the position where the food is placed in the cavity according to the thermal radiation imaging pattern, and feedback it to the control chip. Through an algorithm, the central position of the food can be judged, so as to adjust the angle of the graphite heating tube, so that the heat radiation heats towards the central position of the food. Both ends of the graphite heating tube are connected to a rotating motor 50, and the rotation of the motor is controlled by a program, so as to achieve the adjustment of the angle of the graphite heating tube.

[0058] The solution of the present invention can adjust the angle of the graphene heating tube according to the position of the food in the cavity, so that the heat radiation heats towards the central position of the food, thereby cooking the food more quickly and effectively, reducing the cooking time, and giving the user a better cooking experience.

[0059] Without reducing the heating power, the present invention utilizes the property that the thermal radiation of the graphite heating sheet 31 is different in different directions, ensuring that the thermal radiation energy is used as much as possible for food cooking. This can not only reduce the situation of overcooked or undercooked food, but also not increase or even reduce the cooking time of the food. The cooking appliance includes a housing, an air duct, a bottom plate, a cavity, a graphite heating tube, a rotating motor 50, a sensor, etc. Since the graphite heating sheet 31 is sheet-shaped, the thermal radiation is not uniform, and the thermal radiation in the vertical direction of the graphite heating sheet 31 is stronger than that in other directions. By adjusting the angle of the graphite heating sheet 31, the direction of the thermal radiation can be made adjustable, thereby achieving the optimal food cooking curve. The solution of the present invention can adjust the angle of the graphene heating tube according to the position of the food in the cavity, so as to cook the food more quickly and effectively, reduce the cooking time, and give users a better cooking experience. Without reducing the heating power, the present invention utilizes the property that the thermal radiation of the graphite heating sheet 31 is different in different directions, ensuring that the thermal radiation energy is used as much as possible for food cooking. This can not only reduce the situation of overcooked or undercooked food, but also not increase or even reduce the cooking time of the food.

[0060] Combined with Figures 4 to 6 , during the cooking process, the position of the food can be automatically detected by the position detection member. The position detection member can cover the entire area for placing food in the cooking cavity. Through the detection of the position detection member, the position of the food can be locked, that is, as Figure 5 shown. At the same time, the position of the food can be transmitted to the controller. Through the control of the controller, for this specific food position, the heating member is adjusted, so as to achieve heating of the specific position. Among them, as Figure 6 shown, by rotating the heating member, the surface with the maximum thermal radiation power in the heating member is faced towards the food, thereby effectively improving the cooking efficiency and effect. Of course, as described above, in the present invention, before obtaining the food position, the position of the heating member can be adjusted according to the cooking requirements. Heating with the maximum thermal radiation power of the heating member as described above is only a specific embodiment of the present invention, and is not a limitation on the protection scope of the present invention.
