[0060] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0063] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0064] As described in the background technology above, when the oven is used outdoors, the baking tray or grill may not be kept level. On the one hand, this will affect the use of the oven, and on the other hand, it will cause the food grease to not be timely and completely drained into the grease collecting cup, posing certain safety hazards.

[0065] Based on this, the present invention provides an oven leveling system and method, which detects the inclination of a baking tray in a first direction by a first sensor, and detects the inclination of the baking tray in a second direction by a second sensor, thereby adjusting the action of a lifting mechanism respectively according to the detected inclinations in the first direction and the second direction, so as to adjust the height of each lifting mechanism, thereby automatically adjusting the baking tray when the baking tray is tilted to keep the baking tray level, thereby reducing the impact on the use of the oven and improving the safety of the oven.

[0066] Combine the following Figures 1 to 5 , describing an embodiment of the present invention.

[0067] According to an embodiment of the present invention, on the one hand, a baking oven leveling system is provided. Figure 1 Schematic diagram of the structure of a baking oven leveling system according to an embodiment of the present invention. Figure 1 As shown, the system includes: a baking tray 1, a plurality of lifting mechanisms 2, a first sensor 3, a second sensor 4 and a controller 5.

[0068] In the embodiment of the present invention, the baking tray 1 includes a first side 11 arranged along a first direction and a second side 12 arranged along a second direction, and the first side 11 and the second side 12 are adjacent sides. The first direction and the second direction are two directions determined based on the plane where the baking tray 1 is located. The first direction corresponds to the horizontal direction in the plane, that is, the lateral direction in the plane; the second direction corresponds to the vertical direction in the plane, that is, the longitudinal direction in the plane; the first direction is perpendicular to the second direction.

[0069] In one embodiment, the first side 11 of the baking tray 1 is arranged along the first direction, which means that the angle of the first side 11 relative to the first direction is less than a preset angle; the second side 12 of the baking tray 1 is arranged along the second direction, which means that the angle of the second side 12 relative to the second direction is less than a preset angle. If the angle of the first side 11 relative to the first direction and the angle of the second side 12 relative to the second direction are both 0, then the baking tray 1 is a rectangle; that is, the shape of the baking tray 1 is not limited to a rectangle, but can be a parallelogram, a trapezoid, or other shapes.

[0070] In the embodiment of the present invention, Figure 1As shown, among the multiple lifting mechanisms 2, the first end of each lifting mechanism 2 can be fixed to the bottom of the baking tray 1, lifting the baking tray 1, so that the inclination angle of the baking tray 1 relative to the horizontal plane can be adjusted following the change in the height of the lifting mechanism 2, so that the baking tray 1 can be adjusted to a horizontal state by adjusting the height of the lifting mechanism 2. Optionally, considering that the user may need to take or replace the baking tray 1, the lifting mechanism 2 can only serve as a supporting component, supporting the baking tray 1 at the bottom of the baking tray 1, and being fixedly connected to the baking tray 1.

[0071] In one embodiment, the system further comprises an oven base, and the second end of the lifting mechanism 2 is fixed on the oven base.

[0072] In the embodiment of the present invention, Figure 1 As shown, the first sensor 3 is arranged on the first side 11; the first sensor 3 is a tilt sensor, which is used to detect the tilt of the baking tray 1 in the first direction. The second sensor 4 is arranged on the second side 12; the second sensor 4 is a tilt sensor, which is used to detect the tilt of the baking tray 1 in the second direction.

[0073] In the implementation of the present invention, Figure 1 As shown, the controller 5 is connected to the first sensor 3, the second sensor 4 and the plurality of lifting mechanisms 2 respectively, and the controller 5 is used to adjust the action of the lifting mechanism 2 based on the measurement results of the first sensor 3 and the second sensor 4, so as to adjust the baking tray 1 to a horizontal state.

[0074] In one embodiment, since the baking tray 1 will be subjected to high-temperature baking, there will be certain safety hazards if a wired connection is used. Therefore, in order to improve the safety of the baking tray 1 when in use, a wireless communication connection is adopted between the first sensor 3 and the second sensor 4 and the controller 5, and the first sensor 3 and the second sensor 4 transmit the detected data to the controller 5 via wireless communication.

[0075] In one embodiment, the controller 5 can be fixed on the oven and connected to each lifting mechanism 2 by wire; the controller 5 can also be a component independent of the oven and connected to the first sensor 3, the second sensor 4 and each lifting mechanism 2 by wireless communication.

[0076] In one embodiment, the system further comprises a control switch, which is connected to the controller 5; the control switch and the controller 5 can be integrated into the same component. The control switch is used to turn on or off the adjustment of the level of the baking tray 1, so that the user can adjust the baking tray 1 according to needs.

[0077] In one embodiment, Figure 2 yes Figure 1 Rear view of the oven leveling system shown in Figure 2As shown, the number of lifting mechanisms 2 can be 4, and the 4 lifting mechanisms 2 correspond to the four corners of the baking tray 1 respectively. The 4 lifting mechanisms 2 include a first lifting mechanism, a third lifting mechanism, a third lifting mechanism, and a fourth lifting mechanism; wherein the first lifting mechanism and the third lifting mechanism are arranged near the first side 11, the third lifting mechanism and the fourth lifting mechanism are arranged near the third side 13 of the baking tray 1, and the third side 13 is opposite to the first side 11. At the same time, the first lifting mechanism and the third lifting mechanism are arranged near the second side 12, the third lifting mechanism and the fourth lifting mechanism are arranged near the fourth side 14, and the fourth side 14 is opposite to the second side 12. That is, in the first direction, the first lifting mechanism and the third lifting mechanism, the third lifting mechanism and the fourth lifting mechanism respectively form a group of lifting mechanisms 2; in the second direction, the first lifting mechanism and the third lifting mechanism, the third lifting mechanism and the fourth lifting mechanism respectively form a group of lifting mechanisms 2.

[0078] In one embodiment, in the first direction, the first working distances from the first sensor 3 to each lifting mechanism 2 in each group of lifting mechanisms 2 are equal; that is, when each lifting mechanism 2 in a group of lifting mechanisms 2 is projected in the first direction, the first sensor 3 is located at the center of the projection point corresponding to each lifting mechanism 2. Figure 1 and Figure 3 As shown in the figure, in the first direction, the first working distance from the first sensor 3 to the first lifting mechanism is equal to the first working distance from the first sensor 3 to the third lifting mechanism, and the first working distance from the first sensor 3 to the third lifting mechanism is equal to the first working distance from the first sensor 3 to the fourth lifting mechanism. Therefore, when the lifting mechanism 2 is adjusted with the first sensor 3 as the detection reference in the first direction, the height deviations of the first lifting mechanism and the third lifting mechanism, and the height deviations of the third lifting mechanism and the fourth lifting mechanism relative to the horizontal plane where the first sensor 3 is located are equal in magnitude but opposite in direction, which can simplify the calculation of adjusting the height, so as to realize the rapid adjustment of the lifting mechanism 2, and thus the baking tray 1 can be quickly adjusted to be horizontal in the first direction.

[0079] In one embodiment, in the second direction, the second working distances from the second sensor 4 to each lifting mechanism 2 in each group of lifting mechanisms 2 are equal; that is, when each lifting mechanism 2 in a group of lifting mechanisms 2 is projected in the second direction, the second sensor 4 is located at the center of the projection point corresponding to each lifting mechanism 2. Figure 1 and Figure 3As shown in the figure, in the second direction, the second working distance from the second sensor 4 to the first lifting mechanism is equal to the second working distance from the third sensor to the third lifting mechanism, and the second working distance from the second sensor 4 to the third lifting mechanism is equal to the second working distance from the second sensor 4 to the fourth lifting mechanism. Therefore, when the lifting mechanism 2 is adjusted with the second sensor 4 as the detection reference in the second direction, the height deviations of the first lifting mechanism and the third lifting mechanism, and the height deviations of the third lifting mechanism and the fourth lifting mechanism relative to the horizontal plane where the second sensor 4 is located are equal in magnitude but opposite in direction, which can simplify the calculation of height adjustment, so as to realize rapid adjustment of the lifting mechanism 2, and thus the baking tray 1 can be quickly adjusted to be horizontal in the second direction.

[0080] In one embodiment, in the first direction, the first working distances between the first sensor 3 and each lifting mechanism 2 are equal, that is, the first working distances between the first sensor 3 and not only each lifting mechanism 2 in each group of lifting mechanisms 2 are equal, but also between each group of lifting mechanisms 2 are equal. When the lifting mechanism 2 is adjusted by taking the first sensor 3 as the detection reference in the first direction, the height deviations of the first lifting mechanism and the third lifting mechanism, and the height deviations of the third lifting mechanism and the fourth lifting mechanism relative to the horizontal plane where the first sensor 3 is located are the same, thereby further simplifying the calculation of adjusting the height.

[0081] In one embodiment, in the second direction, the second working distances between the second sensor 4 and each lifting mechanism 2 are equal, that is, the second working distances between the second sensor 4 and not only each lifting mechanism 2 in each group of lifting mechanisms 2 are equal, but also between each group of lifting mechanisms 2 are equal. When the lifting mechanism 2 is adjusted by taking the second sensor 4 as the detection reference in the second direction, the height deviations of the first lifting mechanism and the third lifting mechanism, and the height deviations of the third lifting mechanism and the fourth lifting mechanism relative to the horizontal plane where the second sensor 4 is located are the same, thereby further simplifying the calculation of adjusting the height.

[0082] The oven leveling system of the present invention detects the inclination of the baking tray 1 in a first direction by the first sensor 3, and detects the inclination of the baking tray 1 in a second direction by the second sensor 4, thereby adjusting the action of the lifting mechanism 2 according to the detected inclinations in the first direction and the second direction, so as to adjust the height of each lifting mechanism 2, so as to automatically adjust the baking tray 1 when the baking tray 1 is tilted, so that the baking tray 1 remains level, thereby reducing the impact on the use of the oven and improving the safety of the oven.

[0083] According to an embodiment of the present invention, on the other hand, a method for leveling an oven is provided, and the method for leveling an oven can be applied to the oven leveling system as described above. Figure 3 is a flow chart of a method for leveling an oven according to an embodiment of the present invention, such as Figure 3As shown, the method may include the following steps:

[0084] Step 310: In response to the leveling of the baking tray 1 , the heights of the plurality of lifting mechanisms 2 are adjusted to a preset height.

[0085] In the embodiment of the present invention, when a request for leveling the baking tray 1 is obtained, the controller 5 responds to the leveling of the baking tray 1. At the same time, since the lifting mechanism 2 has an adjustment limit, the adjustment limit will limit the height of the lifting mechanism 2 to rise or fall, so the height adjustment of multiple lifting mechanisms 2 is preset to a certain height to reserve a certain adjustment for the subsequent leveling process, so as to avoid the baking tray 1 being unable to be adjusted to a horizontal state due to the height adjustment of the lifting mechanism 2 reaching the adjustment limit.

[0086] In one embodiment, the leveling request for the baking tray 1 can be sent to the controller 5 by the control switch, that is, it is generated by the user triggering the control switch; at the same time, the height of the lifting mechanism 2 is adjusted to the preset height only when a response is generated to the leveling of the baking tray 1. In the subsequent leveling process and use process, since the height of each lifting mechanism 2 has been adjusted, adjusting the height of the lifting mechanism 2 to the preset height may cause the height of the lifting mechanism 2 to reach the adjustment limit, which in turn affects the leveling of the baking tray 1. Therefore, when the baking tray 1 is leveled twice or more subsequently, the height of the lifting mechanism 2 will no longer be adjusted to the preset height.

[0087] Step 320: respectively obtain the first working distance and the second working distance of the plurality of lifting mechanisms 2 .

[0088] In the embodiment of the present invention, the first working distance is the distance between the corresponding lifting mechanism 2 and the first sensor 3 in the first direction, and the second working distance is the distance between the corresponding lifting mechanism 2 and the second sensor 4 in the second direction. The first working distance and the second working distance may be predetermined, that is, the position of the baking tray 1 placed on the lifting mechanism 2 is fixed; the first working distance and the second working distance may also be determined after the baking tray 1 is placed by measuring with a sensor that can be used for distance measurement, such as an infrared sensor, that is, the position of the baking tray 1 placed on the lifting mechanism 2 may not be fixed.

[0089] Step 330: Acquire first tilt data of the first sensor 3 , and determine first adjustment heights corresponding to the plurality of lifting mechanisms 2 respectively based on the first working distance and the first tilt data.

[0090] In the embodiment of the present invention, the first tilt data of the first sensor 3 is the relevant tilt data of the baking tray 1 in the first direction, which may include information such as the tilt angle and tilt direction of the baking tray 1 in the first direction. Based on the first working distance of each lifting mechanism 2 and the first tilt data, the first adjustment height corresponding to each lifting mechanism 2 is determined respectively; wherein the positive or negative value of the first adjustment height indicates the height adjustment direction of the corresponding lifting mechanism 2, and the specific value of the first adjustment height indicates the height size that the corresponding lifting mechanism 2 needs to adjust.

[0091] Step 340: Based on the preset height and the corresponding first adjustment height, respectively adjust the heights of the plurality of lifting mechanisms 2 .

[0092] In the embodiment of the present invention, since different preset heights have different relative positions with respect to the adjustment limit of the lifting mechanism 2, the adjustment capabilities in each height adjustment direction corresponding to different preset heights are also different. Therefore, when the baking tray 1 is adjusted to be horizontal in the first direction, the corresponding height adjustment methods are also different for different preset heights. When the baking tray 1 is adjusted to be horizontal in the first direction, the adjustment height of each lifting mechanism 2 is determined in combination with the preset height and the corresponding first adjustment height, and the height of each lifting mechanism 2 is adjusted respectively based on the corresponding adjustment height.

[0093] In one embodiment, the adjustment height of each lifting mechanism 2 is determined in combination with the preset height and the corresponding first adjustment height; the same as the first adjustment height, the positive or negative value of the obtained adjustment height indicates the height adjustment direction of the corresponding lifting mechanism 2, and the specific value of the adjustment height indicates the height that the corresponding lifting mechanism 2 needs to be adjusted. The height adjustment direction of the lifting mechanism 2 is determined based on the positive or negative value of the adjustment height; if the adjustment height is a positive value, it indicates that the height adjustment direction of the lifting mechanism 2 is ascending, and if the adjustment height is a negative value, it indicates that the height adjustment direction of the lifting mechanism 2 is descending. The height value of the adjustment height is used as the height that the lifting mechanism 2 needs to adjust, and the height of the lifting mechanism 2 is adjusted according to the determined height adjustment direction, so that the baking tray 1 is adjusted to the horizontal in the first direction.

[0094] Step 350: Acquire second tilt data of the second sensor 4, and determine second adjustment heights corresponding to the plurality of lifting mechanisms 2 respectively based on the second working distance and the second tilt data.

[0095] In the embodiment of the present invention, the second tilt data of the second sensor 4 is the relevant tilt data of the baking tray 1 in the second direction, which may include information such as the tilt angle and tilt direction of the baking tray 1 in the second direction. Based on the second working distance of each lifting mechanism 2 and the second tilt data, the second adjustment height corresponding to each lifting mechanism 2 is determined respectively; wherein the positive or negative value of the second adjustment height indicates the height adjustment direction of the corresponding lifting mechanism 2, and the specific value of the second adjustment height indicates the height size that the corresponding lifting mechanism 2 needs to adjust.

[0096] Step 360: Based on the preset height and the corresponding second adjustment height, the heights of the plurality of lifting mechanisms 2 are adjusted respectively.

[0097] In the embodiment of the present invention, as shown in the above step 340, different preset heights correspond to different adjustment capabilities in each height adjustment direction, so different preset heights correspond to different height adjustment methods when the baking tray 1 is adjusted to be horizontal in the second direction. When the baking tray 1 is adjusted to be horizontal in the second direction, the adjustment height of each lifting mechanism 2 is determined in combination with the preset height and the corresponding second adjustment height, and the height of each lifting mechanism 2 is adjusted respectively based on the corresponding adjustment height.

[0098] In one embodiment, the adjustment height of each lifting mechanism 2 is determined in combination with the preset height and the corresponding second adjustment height; the same as the second adjustment height, the positive or negative value of the obtained adjustment height indicates the height adjustment direction of the corresponding lifting mechanism 2, and the specific value of the adjustment height indicates the height that the corresponding lifting mechanism 2 needs to be adjusted. The height adjustment direction of the lifting mechanism 2 is determined based on the positive or negative value of the adjustment height; if the adjustment height is a positive value, it indicates that the height adjustment direction of the lifting mechanism 2 is ascending, and if the adjustment height is a negative value, it indicates that the height adjustment direction of the lifting mechanism 2 is descending. The height value of the adjustment height is used as the height that the lifting mechanism 2 needs to adjust, and the height of the lifting mechanism 2 is adjusted according to the determined height adjustment direction, so that the baking tray 1 is adjusted to the horizontal in the second direction.

[0099] In one embodiment, according to the height position of the preset height relative to the adjustment limit, the preset height can be divided into the following two situations: the preset height is between the minimum adjustment height and the maximum adjustment height, and the preset height is the minimum adjustment height or the maximum adjustment height. Among them, the minimum adjustment height corresponds to the adjustment height of the descending limit in the adjustment limit, and the maximum adjustment height corresponds to the adjustment height of the ascending limit in the adjustment limit. Therefore, based on different situations of the preset height, the above steps 340 and 360 can be divided into the following two situations:

[0100] In the first case, the preset height is between the minimum adjustment height and the maximum adjustment height. At this time, the lifting mechanism 2 has a certain adjustment capability in both the ascending and descending height adjustment directions. Therefore, the height position of the first sensor 3 can be used as the height reference for adjustment in the first direction, and the height position of the second sensor 4 can be used as the height reference for adjustment in the second direction. Since the first adjustment height is calculated based on the first tilt data detected by the first sensor 3, which is itself calculated based on the first sensor 3, the first adjustment height is ultimately used to adjust the height of each lifting mechanism 2 to a height that is horizontal in the first direction; similarly, the second adjustment height is ultimately used to adjust the height of each lifting mechanism 2 to a height that is horizontal in the second direction.

[0101] In the first case, the above step 340 includes the following steps: based on the corresponding first adjustment height, the heights of the plurality of lifting mechanisms 2 are adjusted respectively. At this time, the height adjustment direction of the corresponding lifting mechanism 2 is determined based on the positive or negative value of the first adjustment height, and based on the specific data corresponding to the first adjustment height, the height of each lifting mechanism 2 is adjusted according to the determined height adjustment direction, so that the baking tray 1 is adjusted to be horizontal in the first direction.

[0102] In the first case, the above step 360 includes the following steps: based on the corresponding second adjustment height, the heights of the plurality of lifting mechanisms 2 are adjusted respectively. At this time, the height adjustment direction of the corresponding lifting mechanism 2 is determined based on the positive or negative value of the second adjustment height, and based on the specific data corresponding to the second adjustment height, the height of each lifting mechanism 2 is adjusted according to the determined height adjustment direction, so that the baking tray 1 is adjusted to be horizontal in the second direction.

[0103] In the second case, the preset height is the minimum adjustment height or the maximum adjustment height. At this time, the lifting mechanism 2 has the adjustment capability only in the rising or falling height adjustment direction. Therefore, it is necessary to determine a height reference based on the preset height and the first adjustment height or the second adjustment height so that the height adjustment directions of all lifting mechanisms 2 are consistent and they are all adjusted toward the height reference.

[0104] In the second case, Figure 4 1 is a flow chart of adjusting the height of the lifting mechanism based on the preset height and the first adjustment height when the preset height is the minimum adjustment height or the maximum adjustment height in a method for leveling an oven according to an embodiment of the present invention, such as Figure 4 As shown, the above step 340 includes the following steps:

[0105] Step 410: Determine a height reference based on a preset height and a corresponding first adjustment height.

[0106] In the embodiment of the present invention, the method for determining the height reference is different according to the preset height. Specifically, according to the adjustment limit corresponding to the preset height, the height adjustment direction that the lifting mechanism 2 currently has the adjustment capability is determined, and it is used as the target adjustment direction; among the lifting mechanisms 2, the height adjustment direction corresponding to the first adjustment height is opposite to the target adjustment direction, and the lifting mechanism 2 with the largest corresponding height value is used as the target lifting mechanism, and the current height of the target lifting mechanism is also the height reference.

[0107] In one embodiment, if the preset height is the minimum adjustment height, that is, the lifting mechanism 2 is currently at the lowering limit position, the lifting mechanism 2 only has the adjustment capability in the ascending height adjustment direction, that is, the target adjustment direction is the ascending height adjustment direction. In this case, the lifting mechanism 2 whose corresponding first adjustment height is a negative value, that is, corresponding to the descending height adjustment direction, and whose height value is the largest, that is, the lifting mechanism 2 with the highest current height, is used as the target lifting mechanism, and the current height of the target lifting mechanism is used as the height reference.

[0108] In one embodiment, if the preset height is the maximum adjustment height, that is, the lifting mechanism 2 is currently at the ascending limit position, the lifting mechanism 2 only has the adjustment capability in the descending height adjustment direction, that is, the target adjustment direction is the descending height adjustment direction. In this case, the lifting mechanism 2 with the first adjustment height of each lifting mechanism 2 being a positive value, that is, corresponding to the ascending height adjustment direction, and having the largest height value, that is, the lifting mechanism 2 with the lowest current height, is used as the target lifting mechanism, and the current height of the target lifting mechanism is used as the height reference.

[0109] Step 420: Based on the height reference and the first adjustment heights corresponding to the plurality of lifting mechanisms 2 , respectively determine the target adjustment heights corresponding to the plurality of lifting mechanisms 2 .

[0110] In the embodiment of the present invention, the target adjustment height of the lifting mechanism 2 corresponding to the height reference, that is, the target lifting mechanism, is determined to be 0; for other lifting mechanisms 2, it is necessary to adjust the height of the lifting mechanism 2 to be consistent with the target lifting mechanism, so the adjustment height of the lifting mechanism 2 is actually the height difference of the lifting mechanism 2 relative to the target lifting mechanism. Since the first adjustment height is the adjustment height calculated with the first sensor 3 as the height reference, the first adjustment height is actually the height difference of each lifting mechanism 2 relative to the first sensor 3. Therefore, by subtracting the first adjustment height corresponding to the lifting mechanism 2 from the first adjustment height corresponding to the target lifting mechanism, the height difference of each lifting mechanism 2 relative to the target lifting mechanism, that is, the target adjustment height, can be obtained.

[0111] Step 430: Based on the corresponding target adjustment heights, adjust the heights of the plurality of lifting mechanisms 2 respectively.

[0112] In the embodiment of the present invention, the height of each lifting mechanism 2 is adjusted based on the corresponding target adjustment height, so that the height of each lifting mechanism 2 is adjusted to the height reference, so that the baking tray 1 reaches a level in the first direction.

[0113] In the second case, Figure 5 1 is a flow chart of adjusting the height of the lifting mechanism based on the preset height and the second adjustment height when the preset height is the minimum adjustment height or the maximum adjustment height in a method for leveling an oven according to an embodiment of the present invention, such as Figure 5 As shown, the above step 360 includes the following steps:

[0114] Step 510: Determine a height reference based on the preset height and the corresponding second adjusted height.

[0115] In the embodiment of the present invention, the target adjustment direction can be determined by referring to the method described in the above step 410, and based on the target adjustment direction and the second adjustment height, the target lifting mechanism can be determined from multiple lifting mechanisms 2 to obtain a height reference, which will not be repeated here.

[0116] Step 520: Based on the height reference and the second adjustment heights corresponding to the plurality of lifting mechanisms 2 , respectively determine the target adjustment heights corresponding to the plurality of lifting mechanisms 2 .

[0117] In an embodiment of the present invention, the method described in the above step 420 can be referred to, the target adjustment height corresponding to the target lifting mechanism is determined to be 0, and the second adjustment height corresponding to the other lifting mechanisms 2 is subtracted from the second adjustment height corresponding to the target lifting mechanism to obtain the target adjustment height corresponding to the other lifting mechanisms 2, which will not be repeated here.

[0118] Step 530: Based on the corresponding target adjustment heights, adjust the heights of the plurality of lifting mechanisms 2 respectively.

[0119] In the embodiment of the present invention, the height of each lifting mechanism 2 is adjusted based on the corresponding target adjustment height, so that the height of each lifting mechanism 2 is adjusted to the height reference, so that the baking tray 1 reaches a level in the second direction.

[0120] In one embodiment, the two situations described above are methods of adjusting the height of the lifting mechanism 2 after responding to the leveling of the baking tray 1 and adjusting the height of the lifting mechanism 2 to a preset height. In the subsequent secondary leveling process of the baking tray 1, since there is no step of adjusting the height of the lifting mechanism 2 to a preset height, the height of each lifting mechanism 2 can be directly adjusted according to the calculated first adjustment height and second adjustment height to adjust the baking tray 1 to a horizontal state.

[0121] In one embodiment, in the subsequent secondary leveling process of the baking tray 1, a height reference that causes the lifting mechanism 2 to reach the adjustment limit can also be determined first, and the adjustment height can be re-determined based on the height reference and the height of the lifting mechanism 2 can be adjusted accordingly. Considering that after the last height adjustment of the lifting mechanism 2, the lifting mechanism 2 that is closer to the descending limit or the ascending limit is more likely to reach the descending limit or the ascending limit during the next height adjustment, the current adjustment height of each lifting mechanism 2 relative to the descending limit is obtained, the current adjustment height is added to the corresponding first adjustment height, and the lifting mechanism 2 whose addition result is closest to the adjustment height corresponding to the descending limit or the ascending limit is used as the target lifting mechanism, and the current height of the target lifting mechanism is used as the height reference to determine the target adjustment height corresponding to each lifting mechanism 2.

[0122] In one embodiment, the first tilt data includes a first tilt angle and a first tilt direction; wherein the first tilt angle is used to characterize the tilt angle of the baking tray 1 in the first direction, and the first tilt direction is used to characterize the tilt direction of the baking tray 1 in the first direction. Figure 6 is a schematic diagram of a process for determining a first adjustment height in a method for leveling an oven according to an embodiment of the present invention. Figure 6 As shown, in the above step 330, based on the first working distance and the first tilt data, the first adjustment heights corresponding to the plurality of lifting mechanisms 2 may include the following steps:

[0123] Step 610: Based on the first tilt angle and the first tilt direction in the first tilt data, first tilt angles corresponding to the plurality of lifting mechanisms 2 are determined respectively.

[0124] In the embodiment of the present invention, when one side of the baking tray 1 tilts downward, the other side of the baking tray 1 tilts upward. Therefore, the first tilt direction detected by the first sensor 3 is the tilt direction of one side of the baking tray 1. The side detected by the first sensor 3 is determined by the design of the first sensor 3 and the installation direction of the first sensor 3 on the first side 11.

[0125] In the embodiment of the present invention, the first tilt angle is the angle value of the first tilt angle corresponding to each lifting mechanism 2. If the side where the lifting mechanism 2 is located is the side detected by the first sensor 3, the first tilt direction is the tilt direction corresponding to the lifting mechanism 2; at this time, if the first tilt direction is tilted downward, the first tilt angle is determined to be a positive value; if the first tilt direction is tilted upward, the first tilt angle is determined to be a negative value. If the side where the lifting mechanism 2 is located is not the side detected by the first sensor 3, the first tilt direction is opposite to the tilt direction corresponding to the lifting mechanism 2; at this time, if the first tilt direction is tilted downward, the first tilt angle is determined to be a negative value; if the first tilt direction is tilted upward, the first tilt angle is determined to be a positive value.

[0126] Step 620: Based on the corresponding first working distances and first inclination angles, first adjustment heights corresponding to the plurality of lifting mechanisms 2 are determined respectively.

[0127] In an embodiment of the present invention, on the one hand, based on the magnitude relationship between the first inclination angle and the preset inclination angle, the first adjustment direction corresponding to the first adjustment height is determined, thereby determining the positive and negative values ​​of the first adjustment height; on the other hand, based on the first working distance and the first inclination angle, the first height value corresponding to the first adjustment height is determined, thereby obtaining the first adjustment height corresponding to the first lifting mechanism.

[0128] In one embodiment, if the first inclination angle is greater than the preset inclination angle, the first adjustment direction corresponding to the first adjustment height is determined to be ascending; if the first inclination angle is less than the preset inclination angle, the first adjustment direction corresponding to the first adjustment height is determined to be descending.

[0129] In one embodiment, there is a trigonometric function relationship between the first working distance, the angle of the first inclination angle and the first height value. The ratio of the first height value to the first working distance is the sine value of the angle of the first inclination angle. Therefore, the sine value of the angle of the first inclination angle is multiplied by the ratio of the first working distance to obtain the first height value.

[0130] In one embodiment, if the preset inclination angle is 0, the positive and negative values ​​of the first inclination angle are consistent with the positive and negative values ​​of the first adjustment height. Therefore, the sine value of the first inclination angle and the ratio of the first working distance can be directly multiplied to obtain the first adjustment height.

[0131] In one embodiment, the second tilt data also includes a second tilt angle and a second tilt direction, similar to the first tilt data; accordingly, Figure 7 FIG. 1 is a flow chart of determining a second adjustment height in a method for leveling an oven according to an embodiment of the present invention. Figure 7 As shown, in the above step 350, based on the second working distance and the second tilt data, the second adjustment heights corresponding to the plurality of lifting mechanisms 2 may include the following steps:

[0132] Step 710: Based on the second tilt angle and the second tilt direction in the second tilt data, respectively determine the second tilt angles corresponding to the plurality of lifting mechanisms 2 .

[0133] In the embodiment of the present invention, since when one side of the baking tray 1 tilts downward, the other side of the baking tray 1 will tilt upward, the second tilt direction detected by the second sensor 4 is the tilt direction of one side of the baking tray 1, and the side detected by the second sensor 4 is determined by the design of the second sensor 4 and the installation direction of the second sensor 4 on the second side 13.

[0134] In the embodiment of the present invention, the second inclination angles corresponding to the plurality of lifting mechanisms 2 may be determined respectively with reference to the method described in the above step 610, which will not be described in detail here.

[0135] Step 720: Based on the corresponding second working distances and second inclination angles, respectively determine the second adjustment heights corresponding to the plurality of lifting mechanisms 2 .

[0136] In an embodiment of the present invention, reference can be made to the method described in 620 above to determine the second adjustment direction corresponding to the second adjustment height based on the magnitude relationship between the second inclination angle and the preset inclination angle; based on the second working distance and the second inclination angle, determine the second height value corresponding to the second adjustment height, thereby obtaining the second adjustment height.

[0137] In one embodiment, the first working distances of the plurality of lifting mechanisms 2 are equal, and the second working distances of the plurality of lifting mechanisms 2 are equal. At the same time, the plurality of lifting mechanisms 2 include a first lifting mechanism and a second lifting mechanism disposed near the first side 11, and a third lifting mechanism and a fourth lifting mechanism disposed near the third side 13, wherein the third side 13 is an opposite side to the first side 11; the first lifting mechanism and the third lifting mechanism are disposed near the second side 12, and the second lifting mechanism and the fourth lifting mechanism are disposed near the fourth side 14.

[0138] Under this arrangement of the lifting mechanism 2, in the first direction, the first lifting mechanism and the second lifting mechanism are symmetrical about the first sensor 3, so the first adjustment height corresponding to the first lifting mechanism is opposite to the first adjustment height corresponding to the second lifting mechanism; in the second direction, the positions of the first lifting mechanism and the second lifting mechanism relative to the second sensor 4 are consistent, so the second adjustment height corresponding to the first lifting mechanism is the same as the second adjustment height corresponding to the second lifting mechanism.

[0139] Under this arrangement of the lifting mechanism 2, in the first direction, the third lifting mechanism and the fourth lifting mechanism are symmetrical about the first sensor 3, so the first adjustment height corresponding to the third lifting mechanism is opposite to the first adjustment height corresponding to the fourth lifting mechanism; in the second direction, the positions of the third lifting mechanism and the fourth lifting mechanism relative to the second sensor 4 are consistent, so the second adjustment height corresponding to the third lifting mechanism is the same as the second adjustment height corresponding to the fourth lifting mechanism.

[0140] Under this arrangement of the lifting mechanism 2, in the first direction, the positions of the first lifting mechanism and the third lifting mechanism relative to the first sensor 3 are consistent, so the first adjustment height corresponding to the first lifting mechanism is the same as the first adjustment height corresponding to the third lifting mechanism; in the second direction, the first lifting mechanism and the third lifting mechanism are symmetrical about the second sensor 4, so the second adjustment height corresponding to the first lifting mechanism is opposite to the second adjustment height corresponding to the third lifting mechanism.

[0141] Under this arrangement of the lifting mechanism 2, in the first direction, the positions of the second lifting mechanism and the fourth lifting mechanism relative to the first sensor 3 are consistent, so the first adjustment height corresponding to the second lifting mechanism is the same as the first adjustment height corresponding to the fourth lifting mechanism; in the second direction, the second lifting mechanism and the fourth lifting mechanism are symmetrical about the second sensor 4, so the second adjustment height corresponding to the second lifting mechanism is opposite to the second adjustment height corresponding to the fourth lifting mechanism.

[0142] Therefore, the first adjustment heights and the second adjustment heights corresponding to each lifting mechanism 2 are associated with each other. Only the first adjustment height and the second adjustment height of one lifting mechanism 2 need to be calculated to obtain the first adjustment height and the second adjustment height of other lifting mechanisms, thereby simplifying the calculation of the adjustment height, greatly reducing the amount of data calculation, and realizing rapid adjustment of the lifting mechanism 2.

[0143] The oven leveling method of the present invention determines the first adjustment height of each lifting mechanism 2 according to the first inclination data detected by the first sensor 3 and the distance between each lifting mechanism 2 and the first sensor 3 in the first direction, and adjusts the height of each lifting mechanism 2 based on the first adjustment height, so that the baking tray 1 does not tilt in the first direction; determines the second adjustment height of each lifting mechanism 2 according to the second inclination data detected by the second sensor 4 and the distance between each lifting mechanism 2 and the second sensor 4 in the second direction, and adjusts the height of each lifting mechanism 2 based on the second adjustment height, so that the baking tray 1 does not tilt in the second direction; thus, the height of the lifting mechanism 2 is adjusted according to the first inclination data of the first sensor 3 and the second inclination data of the second sensor 4, so that the baking tray 1 does not tilt in both the first direction and the second direction, so that the baking tray 1 remains level, thereby reducing the impact on the use of the oven and improving the safety of the oven.

[0144] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0145] The specific contents of the above specific implementations only express several implementations of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
