Description
Technical Field
The invention relates to cooking equipment, in particular to large-scale cooking equipment and a leveling method thereof.
Background
The prior art 1 (CN 109386697A) discloses a leveling method of a washing machine, which adopts an inclination sensor to measure the relative inclination of the whole machine of the washing machine relative to the horizontal plane, and when the inclination exceeds a set value, a leveling controller controls a corresponding driving device to act so as to drive a leveling base angle to move up and down to support and level. However, this document does not specifically disclose the leveling process, and the algorithm used in leveling is not clear. If the leveling base angle is driven and the inclination angle is measured at the same time, the process can take a long time to converge and finally level, and even the possibility of always being unable to level exists. There is a problem in that leveling efficiency is low. Furthermore, this document emphasizes that for a four corner supported household appliance, only two fixing feet and two levelling feet are required to achieve the support levelling of the household appliance, without having to provide four levelling feet. However, there is a problem in that when only two leveling feet are provided, true leveling may not be achieved because if the positions of the two fixing feet are not always flat, overall leveling cannot be achieved regardless of how the other two feet are adjusted.
Prior art 2 (CN 111035255 a) discloses a leveling method of a cooking appliance, which sets a height adjusting device on each fulcrum of the cooking appliance, respectively measures the inclination angles of the X-axis and Y-axis directions by an inclination sensor, determines the highest fulcrum of the cooking appliance according to the detection signal of the inclination sensor, and then respectively adjusts the second fulcrum, the third fulcrum and the fourth fulcrum until all the fulcrums are level with the highest fulcrum. The method has the defects that the highest supporting point is determined during each adjustment, then all the supporting points are aligned to the highest supporting point, the method is relatively suitable for miniaturized cooking appliances, the cooking appliance is higher for large-sized cooking appliances, if the highest supporting point is higher initially, the installation space of the cooking appliance is limited, and the working of the large-sized cooking appliances is not facilitated because the center of gravity is too high.
The specific regulation method disclosed in the document is: the method comprises the steps of firstly determining the highest fulcrum in 4 fulcrums, then increasing the heights of the fulcrums in the X-axis direction of the highest fulcrum in the rest fulcrums until the difference between the heights of the fulcrums in the X-axis direction and the highest fulcrum is smaller than a preset threshold value, then increasing the heights of the fulcrums in the Y-axis direction of the highest fulcrum in the rest fulcrums until the difference between the heights of the fulcrums in the Y-axis direction and the highest fulcrum is smaller than the preset threshold value, then detecting whether the flatness meets the requirement, and when the flatness does not meet the requirement, re-determining the highest fulcrum of the cooking utensil, and re-adjusting the heights of the rest fulcrums for the re-determined highest fulcrum. In the leveling method in this patent, the inclination sensor is only used for determining whether the level is horizontal or not and determining the highest pivot point, and the aim at the adjustment is whether the height difference between the respective pivot points is smaller than a threshold value or not, which is based on the assumption that the ground on which the cooking appliance is placed is a plane. This is possible when the cooking appliance is small, but for large cooking appliances the floor space itself is relatively large and the floor may not be absolutely planar, so it is difficult to solve this problem with the leveling method described above.

Detailed Description
Referring to fig. 1-2, the cooking apparatus includes a case 1, a plurality of adjustable supporting legs 2, an inclination sensor 3, a supporting leg driving device and a control device (not shown), wherein the inclination sensor 3 is arranged at a point C at the bottom of the case, the bottom surface of the case where the inclination sensor is located is used as a reference surface S, and the reference surface S is parallel to the upper surface of the case; the tilt sensor 3 is used for measuring: and an included angle theta between the connecting line of the position of the inclination angle sensor or the accelerometer on the reference surface S and the installation position of each supporting leg and the horizontal plane H of the inclination angle sensor or the accelerometer. The vertical projection of the mounting position of the supporting leg on the reference surface S is M point (in fig. 2, the M point coincides with the mounting position of the supporting leg), and the distance between the position C of the sensor and the M point is R, so that the adjustment height of the supporting leg is h=r×sin θ.

For example, an indicator light is provided near each support foot, with different colors indicating an increase in height, a decrease in height, or no adjustment. When the user manually adjusts the support legs, the user can know whether the support legs are adjusted in place or not at any time.
