The utility model by arranging sealing ring between interior pot and pot cover, and the size to sealing circle and do corresponding restriction to the distance between the pot cover of electric pressure cooking saucepan and the corresponding component of interior pot, in electric pressure cooking saucepan without pressure and pressure rise during to operating pressure, pass through sealing ring, all internally pot plays good sealing function with pot cover, thereby guarantee sealing effectiveness, and improved serviceability and the security of electric pressure cooking saucepan.
Accompanying drawing explanation
Fig. 1 is the partial cutaway schematic of interior pot with hermetically-sealed construction one embodiment of pot cover of the utility model electric pressure cooking saucepan.
Realization, functional characteristics and the advantage of the utility model object, in connection with embodiment, are described further with reference to accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of interior pot of electric pressure cooking saucepan and the hermetically-sealed construction of pot cover.Between interior pot and pot cover, sealing ring is set, and size to sealing circle and limiting to the distance between pot cover and the corresponding component of interior pot of electric pressure cooking saucepan, to realize better sealing effectiveness by sealing ring.
With reference to Fig. 1, Fig. 1 is the partial cutaway schematic of interior pot with hermetically-sealed construction one embodiment of pot cover of the utility model electric pressure cooking saucepan.
The interior pot of the electric pressure cooking saucepan that the present embodiment provides and the hermetically-sealed construction of pot cover, comprise interior pot 10, with these interior pot 10 pot covers that are fastened and connected 20, and be arranged between interior pot 10 and pot cover 20, play for internally pot 10 and pot cover 20 sealing ring 30 of sealing function, sealing circle 30 comprises a jut 31, with this along jut 31 round about along two shirt rims 32 of stretching, in the present embodiment, two shirt rims 32 can be set to be symmetrical set with jut 31, certainly also can be asymmetric, only need to guarantee the sealing function of its internal pot 10 and pot cover 20.
In the present embodiment, shirt rim 32 is set within the scope of 5.5mm-7.5mm with respect to the vertical distance of the center line of jut 31, as shown in Figure 1 apart from a.To guarantee in electric pressure cooking saucepan without pressure with in service pressure, this shirt rim 32 and the madial wall of pot cover 20 upper ends or can close contact with the edge of the upper surface of interior pot 10, play sealing function.
In the present embodiment, the external diameter of jut 31 is set to be more than or equal to 2mm, as shown in Figure 1 distance b apart from pot cover 20 with respect to the horizontal range between the internal diameter of the part of jut 31.Equally in order to guarantee in electric pressure cooking saucepan without pressure with in service pressure, the madial wall of jut 31 and the side of pot cover 20 can close contact, plays sealing function.
In the present embodiment, when in electric pressure cooking saucepan during without pressure, the upper surface of jut 31 is the vertical distance with the inwall of this upper surface corresponding part apart from pot cover 20, and the vertical distance of the upper surface of the interior pot 10 of the lower surface of jut 31 distance, need to be set to be more than or equal to 0.2mm, be less than or equal to 2mm, as shown in Figure 1 distance c and d.Like this, even if electric pressure cooking saucepan is interior without pressure, because the upper surface of jut 31 is apart from the vertical distance of the madial wall of pot cover 20, and the vertical distance of the upper surface of the interior pot 10 of the lower surface of jut 31 distance is enough little, thereby interior pot 10 can be sealed with pot cover 20.
In the present embodiment, in the time that electric pressure cooking saucepan internal pressure rises to operating pressure, the upper surface of jut 31 is the vertical distance with the inwall of this upper surface corresponding part apart from pot cover 20, and the vertical distance of the upper surface of the interior pot 10 of the lower surface of jut 31 distance, need to be set to be less than or equal to 4mm, as shown in Figure 1 distance c and d.In the time that electric pressure cooking saucepan work and pot inner pressure rise to normal operating pressure, this distance is less than or equal to 4mm, with guarantee under pressure sealing ring 30 also can with interior pot 10 and pot cover 20 close contacts, play sealing function.
The present embodiment by arranging sealing ring 30 between interior pot 10 and pot cover 20, and the size to sealing circle 30 and do corresponding restriction to the distance between the pot cover 20 of electric pressure cooking saucepan and the corresponding component of interior pot 10, in electric pressure cooking saucepan without pressure and pressure rise during to operating pressure, by sealing ring 30, all internally pot 10 plays good sealing function with pot cover 20, thereby guarantee sealing effectiveness, and improved serviceability and the security of electric pressure cooking saucepan.
The utility model also provides a kind of electric pressure cooking saucepan.
The electric pressure cooking saucepan that the present embodiment provides, comprise the interior pot of electric pressure cooking saucepan and the hermetically-sealed construction of pot cover, this interior pot comprises interior pot 10 with the hermetically-sealed construction of pot cover, with these interior pot 10 pot covers that are fastened and connected 20, and be arranged between interior pot 10 and pot cover 20, be used for the sealing ring 30 that internal pot 10 and pot cover 20 play sealing function, sealing circle 30 comprises a jut 31, with this along jut 31 round about along two shirt rims 32 of stretching, in the present embodiment, two shirt rims 32 can be set to be symmetrical set with jut 31, certainly also can be asymmetric, only need to guarantee the sealing function of its internal pot 10 and pot cover 20.
