Embodiment 2

[0052] The main difference between the cooking utensil of the second embodiment and the first embodiment is that the magnetic matching part is a first magnet, and the magnetic driving device includes a second magnet. The first magnet has a positive pole and a negative pole, and the second magnet likewise has a positive pole and a negative pole. The second magnet is located above the first magnet. When the positive pole (or negative pole) of the second magnet is opposed to the negative pole (or positive pole) of the first magnet, the first magnet and the second magnet attract each other, and the first magnet moves upward under the action of the second magnet, so that The pressure limiting valve opens. As long as it is ensured that the matching relationship between the first magnet and the second magnet remains unchanged before the cooking appliance starts to heat, the pressure limiting valve can be kept normally open. When the positive pole (or negative pole) of the second ma...

Embodiment 3

[0053] The main difference between the cooking utensil in the third embodiment and the first embodiment is that the magnetic matching part is a metal structure, and the magnetic driving device includes a magnetic core and a coil wound outside the magnetic core. When the coil is de-energized, the core is magnetic. The metal structure is attracted by the magnetic core to keep the pressure limiting valve normally open. When the coil is energized, the magnetic field of the magnetic core is cancelled, so that the magnetism of the magnetic core disappears, and the pressure limiting valve resets and closes under the action of gravity.

Abstract

The invention provides a cooking utensil. The cooking utensil comprises a pot body, a pot lid, a driving mechanism and a controller, and the pot body is used for containing cooked food and is internally provided with a heating device; the pot lid lids the pot body and comprises a lid body and a face lid arranged on the lid body, and the lid body is provided with a pressure limiting valve; the driving mechanism is in communication with the controller, the pressure limiting valve keeps often opened, when heating is started, cold air in the pot body is exhausted, and when pressurizing is needed,the controller can control the driving mechanism to drive the pressure limiting valve to be closed. By means of the cooking utensil, the problem of an electric pressure pot in the prior art that pulpeasily overflows from a cold air rod and a cold air hole can be effectively solved.

Description

technical field [0001] The present invention relates to cooking appliances and, in particular, to improvements in pressure limiting valves for cooking appliances. Background technique [0002] Along with the raising of people's living standard, electric pressure cooker has been more and more widely used as the substitute product of traditional pressure cooker, and is loved and loved by consumers in general. In the prior art, a cold air passage for discharging cold air and a cold air rod arranged in the cold air passage are arranged on the pot cover of the electric pressure cooker. When the electric pressure cooker starts to heat, the cold air inside the pot body will be discharged to the outside from the cold air hole on the air-cooling rod. When the pressure in the pot body reaches a certain value, the air-conditioning rod floats up and lifts up, and the rubber ring at the lower end of the air-conditioning rod seals the air-conditioning channel. However, when the electric...
