Additional control or operation of the steam generator 500 in the cooking system is saved to a certain extent, which helps to simplify control of the system and makes the lifting cooking system more intelligent.

Further, the range control of the lifting cooking assembly 200 is controlled through the position sensor 261, so that the stroke range of the lifting cooking assembly 200 is further protected, and the safety of the lifting cooking assembly 200 is higher. Moreover, by setting the position sensor 261, the lifting cooking system can be quickly adjusted in actual lifting height according to the use environment, such as the height of a table and the height of a cooking table, so that the adaptability is wider.

As shown in fig. 1, in the present embodiment, a position sensor 261 is disposed on the docking tube, and the lifting rod 210 and the docking tube 260 cooperate to trigger the position sensor 261. Position sensor 261 adopts contact sensor, and the sensor needs to have certain high temperature resistant and waterproof function, avoids steam to position sensor 261's damage. The position sensor 261 is provided on the docking tube 260 based on the movement of the docking tube 260 to contact and separate from the lift lever 210. When the lifting rod 210 is matched with the connecting tube 260, the position sensor 261 can be directly triggered through extrusion or touch, so that the position sensor 261 is conducted. When the lifting rod 210 is engaged with the docking tube 260, the tray 230 has been lowered to the lowest position and the food material lattice 121 is completely received in the cooking container 100, the steam generator 500 is activated by the engagement of the position sensor 261 and the controller to generate steam, so as to steam-cook the cooking container 100. When cooking is finished, the lifting lever 210 is lifted, the position sensor 261 is stopped, and the steam generator 500 is simultaneously stopped. The lifting driving device 220 drives the lifting rod to move up and down by adopting a screw rod or thread transmission mode. The lead screw or thread transmission mode helps the lifting rod 210 to lift stably, and the lifting rod still keeps stable and accurate lifting under certain load bearing. The device has the characteristics of high transmission efficiency, high precision, stable motion, no creeping phenomenon, long service life and the like. Since the lifting rod 210 not only needs to conduct steam in practical use, but also needs to bear the weight of the supporting plate 230, the transmission is more reliable and effective by adopting a screw rod or a thread.

In this embodiment, the surface of the tray 230 is recessed in the middle of the four circumferential directions, and the steam spray head 231 is located at the lowest position of the surface recess of the tray 230. During cooking, the steam in the cooking container 100 may eventually cool and condense into water droplets on the inner wall of the cooking container 100, the food material grid 121 or the supporting tray 230, and the water droplets may accumulate downward and mostly flow back to the supporting tray 230. The surface of the supporting tray 230 is set to be in a shape that the middle of the four circumferential directions of the surface is concave, so that water drops can be conveniently accumulated, and the water drops flow back into the steam generator 500 along the lifting rod 210 through the steam nozzle 231 arranged at the lowest position, so that the steam water is effectively guided, the water accumulation in the cooking container 100 is avoided, and all parts in the cooking container 100 are protected.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the technical solutions of the present invention, and are not limitations to the specific embodiments of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
