Thus, when the exhaust valve 201 exhausts, the top wall 11 can shield the liquid discharged from the air outlet 202 of the exhaust valve 201 to avoid splashing of the liquid, and the steam discharged from the exhaust valve 201 can be diffused under the blocking of the top wall 11 and discharged from the exhaust hole 14, so that the noise during the exhaust can be effectively reduced.

Specifically, when the cooking appliance 300 such as an electric pressure cooker heats food, moisture in the cooker is heated and evaporated sufficiently, so that a large pressure is generated in the cooker, and the exhaust valve 201 can release part of steam in the cooker through the exhaust hole 14, so that the air pressure in the cooker is stable. The exhaust assembly 200 of the embodiment of the application uses the exhaust valve 201 and the exhaust hood 100 in a combined manner, the exhaust valve 201 is rotatably arranged on the cover body 301, and the exhaust hood 100 is detachably covered on the exhaust valve 201, so that a mixture of liquid and steam discharged from the exhaust valve 201 can reach the exhaust space 13 firstly, wherein the liquid is shielded by the top wall 11, and further the splashing of the liquid can be prevented. The steam can be discharged to the external environment through the exhaust holes 14 on the top wall 11 and/or the side wall 12, and the noise can be reduced when the air is exhausted.

When the exhaust cover 100 is covered on the exhaust valve 201, the blocking portion 111 blocks the air outlet 202 of the exhaust valve 201.

Thus, the shielding portion 111 of the top wall 11 can shield the air outlet 202 of the exhaust valve 201 to prevent the liquid discharged from the air outlet 202 from splashing vertically, and the steam discharged from the air outlet 202 can be diffused to the exhaust hole 14 along the extending portion 112 to be discharged, so that the noise generated when the exhaust valve 201 exhausts can be effectively reduced.

Specifically, the top wall 11 may include a shielding portion 111 located directly above the air outlet 202, so that the vapor and liquid discharged from the air outlet 202 may be sprayed vertically upward on the shielding portion 111 of the top wall 11, and then the vapor may diffuse in the exhaust space 13 to the extension portion 112 and be discharged from the exhaust hole 14 on the extension portion 112 to the environment. The exhaust hole 14 may be provided on the extension portion 112, may be provided on the side wall 12, or may be provided on both the extension portion 112 and the side wall 12.
