In the cooking appliance provided by the above embodiment of the invention, the steam valve 1 is mounted on the upper cover, and the steam inlet 120 of the steam valve 1 is communicated with the steam exhaust hole, so that water steam generated in the cooking appliance can enter the steam valve 1 through the steam exhaust hole, and the steam pressure in the cooking appliance is relatively high, so that rice grains, porridge and the like in the cooking appliance enter the bubble breaking cavity 20 in the steam valve 1 along with the steam, because the longitudinal sectional area of the bubble breaking cavity 20 is gradually smaller from the middle to the two ends, namely, the bubble breaking piece has an inner cavity similar to a submarine, which can extrude the steam, so that rice grains, porridge and the like mixed in the steam are gradually separated from the steam in the bubble breaking cavity 20 and fall back into the bubble breaking cavity 20, a good bubble breaking effect is achieved, and the situation that the rice grains, porridge and the like overflow to the outside of the cooking appliance is effectively avoided, the convenience of cleaning for the user is improved.
In one embodiment of the invention, the cooking appliance is an electric rice cooker.
Of course, the cooking appliance may be other cooking appliances that use a steam valve to prevent rice water and the like from overflowing, besides the rice cooker, and the cooking appliance is within the protection scope of the present invention as long as the design concept of the present invention is not departed.
In summary, according to the steam valve provided by the embodiment of the invention, the bubble breaking piece is arranged in the steam cavity of the valve body, the bubble breaking piece is provided with the bubble breaking cavity, the longitudinal sectional area of the bubble breaking cavity is gradually smaller from the middle part to the two ends, namely, the bubble breaking piece is provided with the inner cavity similar to a submarine, so that when the steam pressure in the cooking appliance is larger, and rice grains, porridge and the like in the cooking appliance enter the bubble breaking cavity in the steam valve along with the steam, the inner cavity similar to the submarine can extrude the steam, so that the rice grains, porridge and the like mixed in the steam are gradually separated from the steam in the bubble breaking cavity and fall back into the bubble breaking cavity, a good bubble breaking effect is achieved, the condition that the rice grains, the porridge and the like overflow to the outside of the cooking appliance is effectively avoided, the convenience for cleaning a user is improved, and the experience effect of the user is improved.
