Embodiment 1

[0044] refer to figure 1 , 2 , the steam valve assembly proposed in Embodiment 1 of the present invention includes a valve body 100 and a sealing device 200 , the valve body 100 is provided with a bonnet 300 , a sealing ring 400 is provided between the bonnet 300 and the valve body 100 , and the valve body 100 is A steam hole 110 is opened, and the sealing device 200 is used for sealing the steam hole 110 . The steam hole 110 of the steam valve assembly is used to release pressure and exhaust steam to the outside. During the cooking process, the internal pressure of the cooking utensil can be released.

[0045] like figure 2 and 3 As shown, a steam hole 110 is opened at the bottom of the valve body 100 in this embodiment. When the sealing device 200 is not provided, the steam hole 110 communicates with the steam channel inside the valve body 100 . One or more steam holes 110 at the bottom of the valve body 100 can be provided. In this embodiment, two steam holes 110 are p...

Embodiment 2

[0058] This implementation proposes a steam valve sealing device, and the sealing device proposed in this embodiment can be applied to the steam valve assembly proposed in Embodiment 1;

[0059] like Figure 7 and 8 As shown, the sealing device 200 of this embodiment includes a sealing body 210, a sealing lip 220 is disposed on one side of the sealing body 210 in the circumferential direction, and a sealing mating surface with the valve body 100 is provided on the lower side of the sealing body 210. 130 fits the installation mating surface 211, the plane where the free end 223 of the sealing lip 220 is located is lower than the plane where the installation mating surface 211 is located; the installed installation mating surface 211 will cooperate with the sealing mating surface 130 after installation, Since the plane where the free end 223 is located is lower than the plane where the installation mating surface 211 is located, the sealing lip 220 will be in a sealed state aft...

Embodiment 3

[0073] like Figure 9 As shown, this embodiment proposes a cooking appliance, including the steam valve assembly 010 and the sealing device 200 as described in Embodiment 1 and Embodiment 2. This cooking appliance can be one of an electric rice cooker or an electric pressure cooker, specifically Including the pot body 012 and the upper cover 014, the upper cover 014 is closed on the pot body 012, the inner tank 013 is placed on the pot body 012, and the upper cover 014 is provided with a vacuum device 015 for vacuuming the inner tank , to achieve accelerated water absorption and preservation functions.

[0074] The pot cover is also provided with a steam valve assembly 010, and the steam valve assembly 010 is provided with a sealing device 200, through which the sealing device 200 can be used to prevent the steam valve assembly from entering the air, and when it is necessary to exhaust steam and pressure during cooking, The steam valve can be connected for exhaust and pressur...

Abstract

The invention discloses a cooking device and a steam valve assembly thereof. The steam valve assembly comprises a valve body and at least one steam hole formed in the valve body and further comprises a sealing device for sealing the at least one steam hole, the sealing device comprises a sealing lip edge arranged on the steam exhaust side of the at least one steam hole, the sealing lip edge is matched with the valve body to form a sealing cavity, the at least one steam hole communicates with the sealing cavity, and the steam exhaust side of the at least one steam hole is located in the sealing cavity; the sealing lip edge is elastically deformed under the negative pressure of the sealing cavity, and matched with the valve body to form a first sealing position enabling a steam valve to be separated; and the sealing lip edge is separated from matching with the valve body under the positive pressure of the sealing cavity to form a second sealing position enabling the steam valve to be connected. According to the cooking device and the steam valve assembly thereof, the good deformation sealing characteristic of the sealing lip edge is utilized, the sealing lip edge is directly utilized to be matched with the valve body to form the sealing cavity, compared with a traditional sealing form, a sealing ring does not need to be arranged on the valve body on the lower side any more, thus the structure is simpler, the cost is lower, and the sealing effect is good.

Description

[0001] 【Technical field】 [0002] The invention relates to kitchen appliances, in particular to a cooking appliance and a steam valve assembly thereof. [0003] 【Background technique】 [0004] Currently commercially available electric rice cookers, the colloid inside the rice grains is difficult to absorb water, the rice grains are hard inside and soft outside, and the taste is not good. In order to solve the problem that the colloid inside the rice grains is difficult to absorb water during the cooking process of the current rice cooker and the food in the pot is easy to oxidize and deteriorate when kept warm for a long time, a vacuum pump can be added to the rice cooker to discharge the air from the pot to become a vacuum low-pressure rice cooker. [0005] Vacuum technology has high requirements on the tightness of the structure, especially the steam port, which is required to be opened at high temperature to allow the steam to escape, and to have a good sealing effect at low...
