A steam valve assembly and electric rice cooker thereof

Abstract

The invention discloses a steam-valve assembly and an electric rice cooker thereof. The steam-valve assembly includes a valve base and a valve cover, the valve cover is detachably arranged on the valve base, the steam-valve assembly further includes a fan-blade assembly and a support column, and the fan-blade assembly is rotatingly arranged on the support column; the steam-valve assembly further includes a first air inlet and a first air outlet, steam which enters from the first air inlet is discharged from the first air outlet, and the fan-blade assembly is driven to rotate; the steam-valve assembly further includes a plurality of foam-breaking turbulence bars arranged on the valve base or the valve cover, the fan-blade assembly rotates and breaks foam, and the foam-breaking turbulence bars squeezing broken foam. The fan-blade assembly is a foam-breaking device mainly for rotating and breaking foam; the plurality of foam-breaking turbulence bars are used cooperatively, wherein the foam-breaking turbulence bars are assistant in breaking foam. The cooperation of the fan-blade assembly and the foam-breaking turbulence bars can rapidly achieve foam breaking and improve the effect of breaking foam.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to a steam valve assembly and an electric rice cooker. Background technique [0002] The steam valve is an essential component of the rice cooker, its purpose is to connect the inside of the cooker with the outside atmosphere; At the same time, among the rice cooker functions, cooking rice and porridge are the functions most used by consumers. However, when many rice cookers cook porridge, consumers report that the porridge is not good enough, the porridge is not thick enough, and the soup is relatively thin. [0003] During the design and development process, it was considered that cooking porridge with high firepower can make the porridge cook better, but during the cooking process, the steam valve channel is relatively small; high-power heating is likely to cause the pot to overflow, which makes it difficult to clean and cause consumption. complained. In order not to affect t...

Problems solved by technology

In actual use, it is found that the fan blade is too small. If it is water vapor, it can drive the fan blade assembly to rotate, but the rotation of the fan blade cannot generate negative pressure; and in order to make the fan blade assembly easy to rotate, the design of the fan blade assembly is small or Place the fan blade assembly directly above the air outlet; in fact, during the porridge cooking process, because the porridge is relatively sticky and the fan blade assembly is light, the steam with viscous liquid is easy to stick to the fan blade assembly. Cause the fan blade assembly to stop rotating

[0005] If the size of the fan blade assembly is designed to be large because of the large starting inertia, the fan blade cannot be driven when the steam is insufficient; and when the steam enters the steam valve from the air inlet, the steam blows the fan blade assembly to rotate; because the inner chamber of the steam valve and the fan Large spaces exist between leaf components, such as figure 1 As shown, when the wind fluid formed by steam flows in a large space, it will cause turbulent flow or turbulent flow due to factors such as the rotation of the fluid; the side of the steam valve has a viscous effect on the wind, which will cause the wind speed to decrease in a gradient. On the side of the valve, the corresponding steam flow rate is lower; the superposition of the above factors will cause the wind loss of the steam, and reduce the wind force that can effectively push the fan blade assembly, resulting in poor rotation of the fan blade assembly
