Description

Technical Field

[0001] The invention belongs to the field of steam ovens, and in particular relates to an embedded intelligent steam oven. Background Art

[0002] At present, in the world, there are only the following food processing methods: frying, stir-frying, deep-frying, steaming, boiling, stewing, and baking. Among these basic processing methods, steaming and baking occupy a considerable proportion. It can be seen that people favor these two processing methods. Some food processing requires both steaming and baking. Some of them need to be steamed first and then baked, and some need to be baked first and then steamed. Simply using a steamer and an oven to complete these two processes is inconsistent in operation, resulting in low efficiency. In addition, the food needs to be taken out from one device and transferred to another, which will also have a negative impact on the quality of the food. Especially today, with the continuous expansion of the market scale, any product has high requirements for production efficiency. In order to improve production efficiency, companies consider putting the steaming and baking processes together and integrating them into one food equipment. As a result, the steam oven came into being and has been continuously developed in recent years. The steam oven has become a commonly used kitchen appliance in modern kitchens. From its inception to today, the performance of the steam oven has been continuously improved.

[0003] Different foods have different requirements for steaming and baking time, steaming and baking temperature and steaming and baking humidity. The most delicious steamed and baked foods can only be obtained under appropriate steaming and baking temperature and steaming and baking humidity.

[0033] like Figures 1 to 10 As shown, an embedded intelligent steam oven includes a case 1, an inner cavity 21, a controller and a control panel 3. The controller is a PLC controller, and the controller is connected to the control panel 3. On the one hand, information is transmitted to the control panel 3, and on the other hand, the switch instructions of the control panel 3 are received to control the electrical components of the steam oven. The control panel 3 is installed at the upper end of the case 1. The control panel 3 is provided with a preset key 4, a display screen 29 and a control key 5, which are interconnected, and the display screen 29 is connected to the PLC controller, so that the display screen 29 displays various detection parameters of the steam oven and the control instructions and preset instructions of the control panel 3, so that the user can fully grasp the operating conditions of the steam oven and facilitate adaptive regulation thereof.

[0034] The PLC controller includes a data acquisition module, an adjustment execution module and a preset module. The data acquisition module is connected to a temperature sensor, a humidity sensor and an air pressure sensor. All three are installed in the inner cavity 21 of the steam oven to detect the temperature, humidity and air pressure of the inner cavity 21 respectively, and obtain the detection parameters. The preset module is connected to the preset key 4 on the control panel 3, sets the preset parameters according to the user's instructions and transmits them to the PLC controller. The adjustment execution module controls the humidifier, the heater and the micro vacuum pump; the humidifier is used to control the humidity of the inner cavity 21, starts the humidifier when it is lower than the preset humidity, and turns off the humidifier when it reaches or exceeds the preset humidity. The heater is used to control the temperature of the inner cavity 21 of the controller, starts the heater when it is lower than the preset temperature, and turns off the heater when it reaches or exceeds the preset temperature; in the actual use of the steam oven, it is found that due to the increase in temperature, the air pressure in the inner cavity 21 of the steam oven is increased. Too high air pressure not only poses a safety hazard, but also affects the steaming and baking effect and the taste of food. When the air pressure is too high, the micro vacuum pump is started to reduce the pressure.

[0035] The present invention automatically adjusts the temperature, humidity and air pressure in the steam oven through a data acquisition module, a PLC controller, a preset module and an adjustment execution module. The temperature, humidity and air pressure signals of the steam oven cavity 21 are monitored in real time by various sensors of the data acquisition module; the temperature parameters, humidity parameters and air pressure parameters are set by the user in advance in the preset module; the PLC controller compares the temperature, humidity and air pressure signals with the preset temperature parameters, humidity parameters and air pressure parameters to obtain the comparison results, and the adjustment execution module starts the corresponding equipment for the data that produces deviations, such as starting the heater when the temperature is out of standard, starting the humidifier when the humidity is out of standard, and so on. The humidity, temperature and air pressure of the steam oven are adjusted in real time, so that the humidity, temperature and air pressure meet the preset requirements during the entire steaming and baking process, thereby improving the steaming and baking effect; one-button control is very convenient.

The signal identification circuit, the misoperation prevention circuit and the execution module are all connected to the PLC controller. The signal conversion circuit identifies the control instructions and preset instructions of the control panel 3, and transmits them to the misoperation prevention circuit. After comparison by the misoperation prevention circuit, it is determined whether it is a misoperation; if it is confirmed to be a misoperation, a signal is sent to the PLC controller and the operation instruction is terminated; if it is confirmed to be not a misoperation, it is transmitted to the signal identification circuit in a normal order, and after identification, it is sent to the PLC controller, and the execution module of the PLC controller executes the operation instruction. The misoperation prevention module is used to identify whether there is a misoperation or a miscommand on the control panel 3, eliminate wrong switches and control instructions, and prevent circuit problems such as short circuit, open circuit, overvoltage or overcurrent in the steam oven circuit, so as to achieve the purpose of safe control and improve the safety of the steam oven.

[0037] The malfunction prevention circuit includes an action comparison part and a timing circuit. The action comparison part is connected to the timing circuit, and the timing circuit is connected to the PLC controller.

If it is a malfunction instruction, a termination instruction is sent to the PLC controller through the timing circuit; if it is not a malfunction instruction, the PLC controller executes normally.
