The electromagnet is arranged at the end part of the ejection cylinder, and the controller controls whether the magnet is conducted or not. And during discharging, the steamer is sucked at the steamer opening, and the steamer is pulled out to the conveying mechanism through retraction of the ejection cylinder.

The embodiment also provides a control method based on the steam box, which comprises a meal preparation step and a meal delivery step:

the meal preparation step comprises steps S101-S102:

s101, after the food steamer is conveyed into an idle unit cavity, binding and recording dish parameters and the unit cavity;

s102, controlling the unit cavity to enter a cooking state, and controlling the unit cavity to enter other working states after detecting that the duration time of the cooking state of the unit cavity reaches the preset time corresponding to the dishes.

Wherein, the step S101 specifically includes the following steps S1011 to S1013:

s1011, when a meal preparation instruction is received, detecting whether the unit cavity is in an idle state, and if the unit cavity is in the idle state, conveying the food steamer into the unit cavity; otherwise, detecting the next unit cavity until detecting a free unit cavity;

s1012, if all the unit cavities are detected and no idle unit cavity exists, sending alarm information and stopping the step of preparing meal;

and S1013, acquiring the dish parameters, and binding and recording the dish parameters and the unit cavity.

The preparation step is that dishes needing to be cooked are cooked automatically, after the dishes needing to be cooked are conveyed by a worker, corresponding dish parameters are selected on the upper computer, the dish parameters comprise basic information of the dishes, cooking time information and the like, the dish parameters can be preset, the worker can directly select the dish parameters and can also set the parameters on site, for example, the dishes are fish, the worker directly selects the dish information corresponding to the fish on the upper computer, or the worker inputs the basic information of the dishes and the information needing to be cooked on the upper computer. After dish parameters are input, binding and recording dish information and an idle unit cavity, wherein the idle unit cavity is a unit cavity with an idle working state and is obtained through detection.

The meal preparation step is described in detail below with reference to specific examples.

In this embodiment, the meal preparation step includes meal preparation layer scheduling and meal preparation actions;

referring to fig. 2, the meal preparation layer schedules as: when a meal preparation instruction is received, meal preparation scheduling calculation starts to prepare, and judgment is started from a first layer of dish id, wherein the dish id is a preset id, and the id is 0, which represents that no food steamer exists in the unit cavity, namely the food steamer is in an idle state. If the first layer of unit cavity does not meet the condition that the dish id is 0, the judgment is accumulated layer by layer, the condition that whether the dish id of the layer where the second layer of unit cavity is located is 0 is continuously judged, and the rest can be done by analogy, if the accumulated layer meets the condition that the dish id is 0, the layer is ready for meal and fed, and the scheduling and meal preparation calculation is completed. If the steam box comprises 6 unit cavities, when the dish id of each unit cavity with six layers is found not to meet the condition that the dish id is 0, and the layer where the dish id is located after accumulation is larger than 6, the steam box gives an alarm (the layer number is judged wrongly).

In the present embodiment, the cooking time of the corresponding dish is determined by: when a certain dish id is prepared, the system judges whether the dish id is matched with the numbers of dishes 1 to 8, when the dish id is matched with the number of one of the dishes, the cooking time of the dish is the cooking time set by the number of the one dish, and on the contrary, if the dish id is not equal to the numbers of the dishes 1 to 8, the steam box gives an alarm (the cooking time of the dish is selected wrongly).

Referring to fig. 3, the meal preparation action is: after the scheduled meal preparation calculation is completed, the food steamer can be conveyed to the corresponding unit cavity by the conveying mechanism. Specifically, when the food steamer is conveyed in place, the number of the food steamer can be judged by the sensor on the conveying mechanism, and the next action can be carried out only after the food steamer is confirmed to be correct. When the number of the food steamers is correct, the target idle food steamer door can be opened, and then the lifting platform can be lifted to the position of the target idle food steamer door. At the moment, the steam box can be pushed to the bridging mechanism by the ejection cylinder, and the steam box is rotated into the steam box through the bridging mechanism. The lift platform is raised to an initial position and the steam box door begins to close. And the steam box starts to cook, and the steam box can cook the corresponding steam product for a certain time according to the setting of the steam product cooking time parameter. After the cooking target layer finishes the cooking work, the steaming product of the layer is changed into a heat preservation state from a cooking state, and the current layer steaming product is proved to have the qualification of meal delivery. After the steam box finishes the flow, the steamed products prepared for meal can be supplied to the upper computer for serving at any time. Wherein, after the cooking work of the cooking target layer is finished, the steaming product of the layer can be changed from the steaming state to the steaming finish state without heat preservation.

The meal-out step comprises step S201:

s201, obtaining a unit cavity where dishes are located, and taking out the steamer when the working state of the unit cavity is not a cooking state.

The step S201 specifically includes the following steps S2011-S2013:

s2011, when a meal delivery instruction is received, acquiring a plurality of corresponding unit cavities according to the meal delivery instruction;

s2012, detecting whether the working state of the unit cavity is a cooking state, and if the working state is the cooking state, detecting the next unit cavity until a unit cavity of which the working state is not the cooking state is obtained; otherwise, directly taking out the food steamer from the unit cavity, and finishing the step of meal delivery;

s2013, if the unit cavity is not obtained according to the meal taking instruction, or the obtained unit cavities are all in a cooking state, alarm information is sent.

The meal-out step is to take out the cooked dishes according to an instruction input by a worker, for example, when the dishes needing to be output are judged to be fish, which dishes in the unit cavities are judged to be fish according to the previously bound record information, so that the condition that a plurality of unit cavities can cook the same dishes at the same time is stored, whether the dishes in the unit cavities are cooked completely is judged, and if the cooking is completed, one unit cavity is selected to have a meal. The meal-out procedure is described in detail below with reference to specific examples.

In this embodiment, the meal delivery step includes meal delivery layer scheduling and meal delivery actions;

referring to fig. 2, the meal delivery layer schedule is: when receiving a meal-out instruction of an upper computer, the meal-out scheduling calculation starts to prepare, wherein the meal-out scheduling calculation can be dish information, and can also be numbering information of a certain unit cavity; in this embodiment, the information of the dish id is judged from the first layer of dish id, if the first layer of dish id is not matched with the dish id issued by the upper computer, the first layer of dish id is accumulated layer by layer, whether the accumulated layer of dish id is matched with the dish id issued by the upper computer or not is continuously judged, and so on, if the condition that the six layers of dish id are not equal to the dish id issued by the upper computer is found, and the layer where the accumulated layer is greater than 6, the steam box alarms (the layer number is judged wrongly). If the accumulated vegetable id of the layer is found to be equal to the vegetable id issued by the upper computer, the next judgment is made, whether the accumulated layer is in the heat preservation state is judged, if the accumulated layer is not in the heat preservation state, the layer-by-layer accumulation is continued, and when the accumulated layer is found to be equal to the vegetable id issued by the upper computer and the layer state is in the heat preservation state, the steam box system goes to the layer to eat, and the dispatching and eating calculation is completed. If the dish id in the six layers of dishes is not equal to the dish id issued by the upper computer or the dish id of a certain layer of the six layers is equal to the dish id issued by the upper computer and the state is not in the heat preservation state, the layer where the dish id is located after accumulation is larger than 6, and the steam box gives an alarm (the layer number is judged wrongly).

For example, the upper computer issues a dish with dish id 2, the system can automatically judge whether the dish of the first layer is 2 from the first layer and is in a heat preservation state, if not, the system accumulates layer by layer and continues to judge the second layer; if so, the meal serving target value is the first layer, and so on.

Referring to fig. 4, the meal delivery action is: after the meal dispatching calculation is completed, the door of the corresponding unit cavity is opened, and the lifting platform is lifted to the position corresponding to the unit cavity. The food steamer is rotated out to the place where the food steamer can be contacted with the electromagnet of the ejection mechanism, and the food steamer is taken to the lifting platform by utilizing the electromagnet on the ejection mechanism. The lift platform is raised to an initial position and the steam box door begins to close. And finishing the meal delivery of the steam box.
