Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a cooking device and an electric rice cooker. Background Art

[0002] With the development of society and the progress of science, people are increasingly pursuing quality of life. Cooking devices such as rice cookers and electric frying pans are widely used in people's daily lives and have become indispensable tools in people's lives.

[0003] A Chinese utility model patent, granted with publication number CN211212699U, discloses an upper cover and a cooking device having the same. The cooking device primarily comprises a cooking body and an upper cover. The upper cover is disposed on the cooking body and defines a cooking space between the upper cover and the cooking body. The upper cover comprises a heat-insulating cover plate and a heating element. The heat-insulating cover plate is disposed facing the cooking space, and the heating element is located on the side of the heat-insulating cover plate facing away from the cooking space. The heating element is used to heat the heat-insulating cover plate, thereby heating evaporated condensed water adhering to the heat-insulating cover plate to prevent water from dripping back into the cooking space, thereby ensuring that the cooked food tastes better. Although the aforementioned cooking device can prevent condensed water from adhering to the heat-insulating cover plate, the heating element is typically activated only during the heat-insulating phase, resulting in low cooking efficiency. Utility Model Content

[0011] an upper heater, the upper heater being provided on the upper cover and located on a side of the heating cover plate facing away from the cooking space, the upper heater being used to heat the heating cover plate; and

[0012] A controller is electrically connected to the lower heater and the upper heater, and the controller has a first operating mode. When the controller is in the first operating mode, the controller controls the lower heater and the upper heater to start, so that the lower heater and the heating cover heat the cooking space.

[0013] The cooking device of the present invention has a controller with a first working mode. When the controller is in the first working mode, the controller controls the lower heater and the upper heater to start up, so that the lower heater and the upper heater heat the cooking space. Among them, the upper heater is started to heat the heating cover, so that the lower heater and the heating cover can be used to heat the inner pot located in the cooking space in an upper and lower three-dimensional manner at the same time, so that the heating of the inner pot is more uniform and efficient, and the heating time can be shortened, thereby improving cooking efficiency.

[0014] In one embodiment, the controller also has a second working mode. When the controller is in the second working mode, the controller controls the lower heater to turn off and the upper heater to start, so that the upper heater heats the heating cover to remove condensed water on the heating cover, preventing the condensed water on the heating cover from dripping onto the food in the inner pot and affecting the taste of the food. At the same time, the additional water receiving box can be eliminated, which can simplify the structure of the cooking device.

[0015] In one embodiment, the cooking device further comprises:

[0016] a lower temperature sensor, the lower temperature sensor being disposed in the cooking body, the probe of the lower temperature sensor being used to connect to the inner pot located in the cooking space;

When the controller is in the first operating mode, the controller is configured to control the heating power of the lower heater and the upper heater based on feedback information from the lower temperature sensor and the upper temperature sensor. When the controller is in the second operating mode, the controller is configured to control the upper heater to be turned off based on feedback information from the upper temperature sensor. In this way, when the controller is in the first operating mode, such as the cooking mode, the lower temperature sensor can be used to monitor the temperature of the inner pot in real time, and the upper temperature sensor can be used to monitor the temperature of the heating cover in real time, so as to accurately control the temperature of the lower heater and the upper heater, thereby preventing the temperature of the inner pot and the heating cover from being too low or too high, improving cooking efficiency and ensuring the cooking taste. When the controller is in the second operating mode, such as the keep warm mode, the upper temperature sensor can be used to monitor the temperature of the heating cover in real time. When the heating cover reaches a preset temperature, the controller controls the upper heater to be turned off in a timely manner based on feedback information from the upper temperature sensor, thereby preventing the temperature of the heating cover from being too low or too high, thereby preventing the taste of the food from being affected. The controller then controls the cooking device to maintain a keep warm state.

[0022] In one embodiment, the lower heater and the upper heater are both electromagnetic heating bodies, and the heating cover and the inner pot located in the cooking space are both magnetic bodies. In this way, when the lower heater and the upper heater are powered on, a magnetic field is generated, and the magnetic heating cover and the inner pot are affected by the above magnetic field to generate heat, which can improve the heating efficiency of the lower heater and the upper heater.

[0023] In one embodiment, the upper cover is provided with a magnetic isolation member located on the side of the upper heater facing away from the heating cover. The magnetic isolation member serves to isolate the magnetic field generated by the upper heater from the top of the upper cover, thereby preventing the upper heater from heating metal utensils located on the top of the upper cover. This prevents accidental burns, improves user safety, and helps reduce heat loss, thereby further improving cooking efficiency.

[0024] In one embodiment, the upper heater includes a winding reel and an electrical connector, the winding reel is provided on the upper cover, the electrical connector is provided on the winding reel, and the electrical connector is electrically connected to the controller to provide power to the upper heater so that the upper heater can start heating.

[0025] In one embodiment, the cooking device further comprises:

[0026] A sealing ring is provided on the heating cover, and when the upper cover is closed, the sealing ring is used to abut against the top of the inner pot located in the cooking space to seal the gap between the upper cover and the inner pot, so that the inner cavity of the inner pot forms a relatively closed space, which can prevent water from leaking out of the inner pot through the gap between the upper cover and the inner pot during cooking, and at the same time, it also helps to reduce heat loss, thereby further improving cooking efficiency.
