Description
Technical Field
The invention relates to the field of household appliances, in particular to an exhaust valve, a cooker cover and a cooking appliance.
Background
The discharge valve of cooking utensils such as traditional electric pressure cooker is at the pressure rise and pressurize in-process, the discharge valve is in static not exhaust state, therefore also be in static pressurize state in the pot body, but when the pot body was in static pressurize state, because do not have gaseous bottom to pot body upper portion from the pot body to flow, therefore can't drive the internal food of pot and carry out the boiling and roll, and then make the internal food of pot present obvious hot water juice stratification phenomenon, therefore the hot water juice of cooking out is not thick and fragrant thick, give the sensation of user's a clear hot water and little water, therefore the taste and the user experience of food have greatly been reduced.
Therefore, how to design a cooking appliance capable of realizing boiling and tumbling of food in the processes of pressure rise and pressure maintaining becomes a problem to be solved at present.
Disclosure of Invention
The present invention is directed to solving at least one of the problems of the prior art or the related art.
The present invention is based on the above problems and provides an exhaust valve.
Another object of the present invention is to provide a pot lid including the above-mentioned exhaust valve.
It is still another object of the present invention to provide a cooking appliance including the above exhaust valve.
In order to achieve the above object, an embodiment of a first aspect of the present invention provides a vent valve, including: the valve comprises a valve body, wherein a gas inlet is formed in a first part of the valve body, a partition is arranged on the end face of a second part of the valve body, a plurality of areas communicated with the gas inlet are defined by the partition and the end face of the second part of the valve body, and the areas are distributed along the circumferential direction of the valve body; the valve cover covers the valve body and seals the plurality of regions, an air outlet communicated with the regions is formed in the valve cover, and the air outlet is located above one end of the regions and surrounds the regions and the air inlet to form an exhaust channel.
According to the exhaust valve of the embodiment of the invention, the outlet is positioned above one end of the area, namely the area is obliquely communicated with the outlet, so that the outlet section of the exhaust channel can extend upwards from the valve body to the circumferential direction of the valve cover in an inclined way, after gas enters the valve body from the gas inlet, the gas can be obliquely discharged from the outlet of the exhaust channel, namely the gas outlet, along the tangential direction of the valve cover, and then the gas can generate thrust force on the exhaust valve in the approximate tangential direction in the discharging process, wherein the thrust force is opposite to the discharging direction of the gas, so that the exhaust valve can be pushed to integrally rotate, and the inside of the pot body can be communicated with the outside when the exhaust valve rotates, namely the electric pressure cooker can exhaust, so that when the electric pressure cooker is electrified and heated, and the pressure in the pot reaches a certain pressure value P, the exhaust valve can be jacked up, so that the electric pressure cooker exhausts, cooking appliances such as the electric pressure cooker can exhaust in the pressure rising and maintaining process, so that food in the cooker body boils and rolls, so that the cooked food such as soup is more thick, fragrant and thick, and the taste and the user experience of the cooked food can be improved.
