In the above embodiment, the backflow channel 17 is formed between the inner wall surface of the steam cavity 10 and the outer wall surface of the bubble breaking cavity 13, the water vapor in the steam discharged through the steam outlet 151 is discharged from the steam outlet 121 after passing through the backflow channel 17, and the rice water, rice grains and the like in the steam discharged through the steam outlet 151 flows back into the cooking utensil through the backflow valve 172 under the action of gravity after passing through the backflow channel 17, so that the rice water, the rice grains and the like are not easy to overflow the steam valve 1, and thus the loss of the nutritional ingredients of the rice is avoided.
Particularly, the backwash valve 172 is in normally open state under ordinary circumstances, make like this steam or the grain of rice that enters into in the steam valve 1 by steam inlet 111, can flow into cooking utensil again by backwash valve 172 after the condensation in to avoided water droplet or grain of rice to remain in steam valve 1, influence the cleanliness factor of steam valve 1, preferably, can set up backwash valve 172 in the lowest position of disk seat, make more water droplet or grain of rice in timely flow back to electric rice cooker through backwash valve 172, further avoid remaining more water droplet or grain of rice in the steam valve 1.
Preferably, the steam outlet 121 is provided with a baffle 122 extending downwards, so that the steam entering the return channel 17 bypasses the baffle 122 and is then discharged from the steam outlet 121, thereby increasing the flow path of the steam, facilitating the rice water, rice grains and the like in the steam to be sufficiently separated from the steam in the flow process, and finally returning to the pot body through the return valve 172.
An embodiment of another aspect of the present invention provides a cooking appliance (not shown in the drawings), comprising: a cover and the steam valve 1 of any of the above embodiments.
Wherein, the upper cover is provided with an installation cavity, and the bottom of the installation cavity is provided with a steam exhaust hole; the steam valve 1 is installed in the installation cavity, and the steam inlet 111 of the steam valve 1 is communicated with the steam exhaust hole.
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 111 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 when the steam pressure in the cooking appliance reaches a certain value, the steam pressure pushes the elastic valve 16 in the steam valve 1 to elastically deform, the steam outlet 151 is opened, so that the water steam in the cooking appliance is exhausted to the outside through the steam outlet 121 on the steam valve 1, and the normal steam exhaust function of the cooking appliance is realized, and in the opening process of the elastic valve 16, bubbles can be squeezed through the extrusion of the elastic valve 16 through the bubbles of the elastic valve 16, so that rice soup is not easy to overflow from the steam valve 1, and the loss of the rice nutrition cost is avoided; if rice grains and other fine particles block the opening of the elastic valve 16 at this stage, the internal pressure of the electric rice cooker is increased, the elastic deformation of the elastic valve 16 is increased, and the opening degree of the elastic valve 16 is increased, so that the rice grains and other fine particles are discharged, and the blockage of a steam outlet is avoided; when steam is not required to be discharged, the elastic valve 16 is in the non-deformation state again, so that the steam cavity 10 on the steam valve 1 is in the closed state, and the beneficial effects of locking the moisture and the fragrance of the rice, improving the taste of the rice and the like are achieved.
In summary, according to the steam valve provided by the embodiment of the invention, the steam outlet on the bubble breaking component is opened or closed by the elastic valve, the steam pressure in the steam valve is larger, the opening degree of the elastic valve is larger, the extrusion effect of the elastic valve on steam mixed with rice grains, porridge soup and the like is larger, and the beneficial effects that the steam outlet is prevented from being blocked by fine particles such as rice grains and the like and bubbles of the rice soup are broken, the rice soup is not easy to overflow, the rice soup is refluxed by the reflux valve, the nutritional ingredients of rice are prevented from being lost and the like are achieved, the elastic valve is in elastic contact with the bubble breaking component in the process of opening or closing the steam outlet, noise is avoided, and the service performance of a product is ensured; and above-mentioned structure, simple structure easily assembles safe and reliable.
