Description
Technical field
The utility model relates to household electrical appliance technical field, more specifically, relates to a kind of hermetically-sealed construction of pressure cooking device.
Background technology
In prior art, the sealing ring that on market, conventional pressure cooking device (for example electric pressure cooking saucepan) uses is the structure that adopts " people " type cross section mostly, then fixes a circular support (being commonly called as steel ring) or fixes a circular cover in pot cover inner side.Sealing ring is enclosed on circular support or circular cover edge, to prevent that sealing ring from coming off in using.For example, the utility model that the patent No. is 200320119448.2 discloses a kind of hermetically-sealed construction of electric pressure cooking saucepan, and sealing ring is between pot cover and circular support.The shortcoming of this structure is: 1, after sealing ring expanded by heating, easily come off; 2, the accuracy of manufacture of circular support, welding precision are difficult to control, and production efficiency and yield rate are low, and production cost is high; 3, the rigidity of circular support is low, is very easily out of shape and affects sealing effectiveness when use; 4, the outward appearance of circular support structure is more low-grade, affects the aesthetic property of whole product, and is difficult to clean.
Utility model content
The utility model is intended to solve the problems of the technologies described above at least to a certain extent.
The purpose of this utility model is to provide a kind of simple and reasonable, and mounting or dismounting are convenient, prevents that sealing ring from coming off in using, the hermetically-sealed construction of the pressure cooking device that production cost is low.
The utility model solves the technical scheme that its technical problem adopts: a kind of hermetically-sealed construction of pressure cooking device, comprise pot cover, interior pot and the sealing ring between pot cover and interior pot, the outside of described sealing ring is provided with multiple flanges, described pot cover is provided with multiple the first through holes corresponding to flange, the anchor ring of described sealing ring is provided with multiple the second through holes corresponding to flange, and described pot cover is provided with multiple protuberances corresponding to the second through hole; When installation, described flange stretches into the first through hole, and described protuberance stretches into the second through hole.
Traditional hermetically-sealed construction be by seal ring set on the circular support or circular cover of pot cover inner side.The internal diameter that must be greater than sealing ring due to the external diameter of circular support or circular cover just can be held sealing ring and not come off, and this can cause the installation and removal of sealing ring very difficult.Particularly, because circular support is easily out of shape, often cause product seal failure and leak gas.In addition, sealing ring can fluff by expanded by heating in product uses, and causes sealing ring meeting Automatic-falling.
Compared with traditional hermetically-sealed construction, the location of sealing ring of the present utility model and connection are that the first through hole by the flange in sealing ring outside being stretched into pot cover is realized, and the assembly and disassembly of sealing ring are very easy to.The effect that protuberance on pot cover stretches into the second through hole is to prevent that sealing ring is under Action of Gravity Field, and its flange skids off the first through hole of pot cover, thereby effectively prevents the Automatic-falling of sealing ring.
In one embodiment, described pot cover is provided with third through-hole, and described protuberance stretches into the second through hole through third through-hole.Preferably, described protuberance is removably fixed on pot cover.This protuberance can be rivet, screw or other prodgers, and it stretches into the second through hole through third through-hole, thereby prevents the Automatic-falling of sealing ring.Alternatively, the utility model also comprises the cover being connected with pot cover, and described protuberance is located on cover.The difference of this replacement scheme is that protuberance is not to be directly fixed on pot cover, but is fixed on cover.That is to say, the fixed form of protuberance has multiple, can be to be removably fixed on pot cover, can be to be also removably fixed on cover, or also can be shaped to one with cover.
In another embodiment, described protuberance is shaped on pot cover.The difference of this replacement scheme has been to cancel the setting of third through-hole, protuberance directly and pot cover be shaped to one.Certainly, in other embodiments, protuberance also can be fixed on pot cover by modes such as riveted joint, welding.
In one embodiment, described flange is 3 ~ 6.Preferably, described flange is 4 and is uniformly distributed circumferentially, to guarantee that sealing ring in use can not come off.
The beneficial effects of the utility model are: compared with traditional hermetically-sealed construction, the assembly and disassembly of sealing ring are very easy to, and effectively prevent the Automatic-falling of sealing ring, guarantee sealing effectiveness.In addition,, because the utility model need to or not arrange circular cover at pot cover inner side welding circular support, structure and technique are greatly simplified, and have effectively improved production efficiency, and have reduced cost.
