Problems solved by technology

However, when using a traditional pressure cooking appliance, such as an electric pressure cooker, when the cooking process is over, the user cannot immediately open the lid of the pot due to the high pressure inside the pressure cooking appliance, and needs to open the pressure limiting valve to exhaust and reduce pressure, or Let the food in the pot cool naturally
It takes a long time for natural cooling. In addition, when the user opens the pressure limiting valve to exhaust and reduce pressure, if the liquid food is cooked in the pot, the liquid food in the pot is easily sprayed by high-pressure gas from the exhaust port. It will bring danger to the user and pollute the surface of the pot body and the environment at the same time.

Embodiment 1

[0017] see figure 1 , which shows the structure of a pressure cooking appliance provided by an embodiment of the present invention, the pressure cooking appliance may include a pot body 1, an upper cover 2 and a cover plate 3; the upper cover and the cover plate form a pot cover; the The pot body 1 is provided with an inner container 9, which forms a cooking cavity with the upper cover 2; wherein, the cover plate 3 is provided with a cooling device 4, and the cooling device 4 is directly in contact with the cooking cavity, so The cooling device 4 is filled with liquid for heat exchange with the cooking cavity;

[0018] The pressure cooking appliance also includes an exhaust device, including: an exhaust passage 10 provided on the pot cover and communicating with the interior of the inner pot, and a pressure limiting valve 11 for controlling the opening and closing of the exhaust passage;

[0019] The pressure cooking appliance further includes a control part configured to use...

Embodiment 2

[0047] Based on the same technical concept as the foregoing embodiments, the embodiments of the present invention provide a control method flow based on the pressure cooking appliance involved in the foregoing embodiments, see image 3 , which can include:

[0048] S301: Use the cooling device and the exhaust device to reduce the pressure in the cooking cavity based on a set pressure reduction strategy.

[0049] For pressure cookers such as figure 1 or figure 2 As shown, the cooling device also includes a water inlet and a water outlet, and the pot body is also provided with a driving water pump and a water tank containing the liquid; the water inlet is connected with the water outlet of the water tank through a water supply pipe, so The water outlet is connected to the water return port of the water tank through the water return pipe to form a circulation loop; the driving water pump is used to drive the liquid in the water tank to circulate in the circulation loop;

Abstract

The embodiment of the invention discloses a pressure cooking appliance and a control method of the pressure cooking appliance. The pressure cooking appliance can include a pot body, an upper cover anda cover plate; the upper cover and the cover plate form a pot cover; an inner container is provided in the pot body to form a cooking cavity with the upper cover; wherein the cover plate is providedwith a cooling device, the cooling device is in direct contact with the cooking cavity, and the cooling device contains a liquid for performing heat exchange with the cooking cavity; the pressure cooking appliance further includes an exhaust device; the exhaust device includes an exhaust channel which is arranged on the pot cover and communicated with the inside of the inner pot, and a pressure limiting valve that controls the opening and closing of the exhaust channel; and the pressure cooking appliance further includes a control part, which is configured to reduce the pressure value in the cooking cavity using the cooling device and the exhaust device based on a preset pressure reduction strategy. Therefore, the pressure in the pressure cooking appliance can be quickly, safely and quietly reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a pressure cooking appliance and a control method for the pressure cooking appliance. Background technique [0002] Pressure cooker has become an indispensable cooking equipment in our kitchen because of its many advantages such as fast cooking, high cooking temperature, good food taste and energy saving. However, when using a traditional pressure cooking appliance, such as an electric pressure cooker, after the cooking process is over, the user cannot immediately open the lid of the pot due to the high pressure inside the pressure cooking appliance, and needs to open the pressure limiting valve to exhaust and reduce pressure, or Let the food in the pot cool down naturally. Natural cooling takes a long time. In addition, when the user opens the pressure limiting valve to exhaust and reduce pressure, if the liquid food is cooked in the pot, the liquid food in the pot...
