Description

Technical Field

[0001] The utility model relates to the technical field of cooking appliances, in particular to an intelligent electric oven. Background Art

[0002] Currently, the level of intelligence of commercial electric ovens is low. They rely on the service staff's frequent observation and work experience to identify different types of skewers and judge their maturity, which takes up a lot of the service staff's working time. If they are not observed in time during peak dining hours, the food may be burnt, causing customers to cancel their orders and affecting brand recognition.

[0003] The heating tubes of electric ovens are all multi-speed fixed-frequency control solutions, which rely on service personnel to control the start and stop and power adjustment of the oven heating tubes. By adjusting the power of the heating tubes, the skewers are cooked. In the middle and late stages of customers' meals, the number of skewers is small, and most of the skewers are vacant, resulting in serious waste of electricity. The heating tubes are multi-speed fixed-frequency power control solutions, and the power adjustment span is too large to achieve detailed temperature control. As the use time increases, the power of the heating tubes decays. If the customer's baking power setting remains unchanged, the baking time will change, which will increase the difficulty of identifying the maturity of the skewers and affect the taste of the skewers. Most electric ovens are designed with single-sided heating at the bottom, and need to cooperate with the desktop motor transmission system to drive the rotation of the skewers to achieve all-round heating of the skewers. Summary of the invention

[0015] Figure 1 is the structural diagram of the intelligent electric grill;

[0016] Figure 2It is a schematic diagram of an intelligent electric grill control system. Detailed implementation manners

[0017] Refer to Figure 1 , the intelligent electric grill includes a tabletop 1, a grill 2, a support frame 3, and a controller (not shown). The grill 2 is located on the tabletop 1. The grill 2 includes two rows of support plates 21 arranged in parallel. A plurality of accommodating grooves 22 are arranged at intervals on the support plates 21. The accommodating grooves 22 on the two rows of support plates 21 are arranged oppositely for accommodating the iron skewers of grilled skewers.

[0018] Along the direction in which the accommodating grooves are arranged, the grill 2 is divided into a plurality of heating zones. Each heating zone corresponds to one or more bottom heating tubes 4. A plurality of temperature sensors 23 corresponding to the plurality of heating zones are arranged on the side surface of the support plate 21.

[0019] The support frame 3 includes a vertical plate 31 and a horizontal plate 32 connected to the vertical plate 31. The vertical plate 31 is fixedly connected to the tabletop 1 and is located on the side of the grill 2. The horizontal plate 32 is located directly above the grill 2. A plurality of top heating tubes 33 are arranged below the horizontal plate 32. Each heating zone corresponds to one or more top heating tubes 33.

[0020] The top heating tubes 33 and the bottom heating tubes 4 adopt variable frequency control of the heating power, and cooperate with the temperature sensors in each heating zone to achieve precise zoning control of the heating temperature.

[0021] One or more image acquisition devices 34 (preferably cameras) are arranged on the side of the vertical plate 31 facing the grill 2 for acquiring the image of the skewers placed on the grill 2. One or more humidity sensors 35 and wind speed sensors 36 are also arranged on the vertical plate 31 and / or the tabletop and / or the support plate 21 (in Figure 1 , the humidity sensor is arranged on the vertical plate 31, and the wind speed sensor 36 is arranged on the tabletop).

[0022] Furthermore, a shelf 37 is also arranged above the horizontal plate 32. A reminder device 5 is installed at a position on the tabletop 1 close to the grill 2 for indicating the current barbecue state. Preferably, the reminder device 5 is an LED lamp, and indicates the barbecue state through color, brightness, and flashing. Those skilled in the art can understand that other reminder devices can also be used instead of the LED lamp, such as speakers, displays, etc.

[0023] Refer to Figure 2 , the control system of the electric grill of the present invention includes an image recognition module, a temperature detection and control module, and an environmental parameter detection module.

[0024] The controller of the intelligent electric grill is connected to the image recognition module and the temperature detection and control module; the image recognition module obtains cooking information based on the images acquired by the image acquisition device 34. The environmental parameter detection module is connected to the humidity detection device and the wind speed detection device, and is used to obtain the humidity and wind speed of the environment.

[0025] The controller determines the cooking strategy (such as the cooking duration and temperature) according to the cooking information and environmental parameters. The temperature detection and control module is used to obtain temperature information, and is connected to the top heating tube and the bottom heating tube, and adjusts the working states of the top heating tube and the bottom heating tube according to the cooking information.

[0026] By collecting information such as the humidity and wind speed of the environment, the cooking duration and temperature are optimized, and then adjusted and controlled through the temperature detection and control module, so that the skewers can be cooked according to the pre-designed cooking strategy, thus having a unified taste in different environments.

[0027] The cooking information includes one or more of the maturity of the skewers, the type of skewers, and the number of skewers. The controller is also connected to the reminder device 5 and controls the working state of the reminder device 5 according to the cooking information.

[0028] For example, when a customer places an order, the kitchen staff prepares the corresponding skewers and seasonings. At the same time, the electric grill calculates the preparation time and preheats the corresponding heating zones of the top heating tube 33 and / or the bottom heating tube 4 according to the preparation time and the number of skewers. After the kitchen staff prepares the skewers and seasonings, they are placed on the grill 2. By preheating the corresponding heating zones in advance by the electric grill and planning the time well, the cooking time is greatly saved. The controller starts cooking according to the cooking strategy.

[0029] The image recognition module monitors the cooking state of the skewers in real time. When the cooking is completed, it reminds the customer to eat through the reminder device 5, and at the same time adjusts the electric grill to the heat preservation state to avoid the skewers being dried out after long-term roasting, which affects the taste.
