Abstract
The utility model relates to a prevent pressure cooker seal structure that sealing washer drops, including pot cover and sealing washer, the pot cover is equipped with two at least ladder planes, upwards divide into first ladder and second ladder in proper order by the pot cover bottom, and its characterized in that distributes on the lateral wall of pot cover second ladder has a plurality of open slots or to the bellied convex closure in inboard, and this corresponds the sealing washer outside distributes and has a plurality of convex closures or recess, and the open slot on the pot cover forms detachable swing joint with the mutual gomphosis of the convex closure on the convex closure of sealing washer, or the convex closure on the pot cover and the recess on the sealing washer. The utility model discloses its beneficial effect of contrast prior art is, and the recess or the convex closure of pot cover and the convex closure or the recess of sealing washer cooperate, dismantle the washing easily, cancel prior art's sealing washer support simultaneously, reduced the manufacturing cost of pressure cooker to a certain extent.
Description
Technical field
The utility model relates to kitchen small household appliances electrical domain, is specifically related to the pressure cooker hermetically-sealed construction that a kind of anti-seal circle comes off.
Background technology
The sealing ring fixed form that electric pressure cooking saucepan adopted on the existing market mainly contains following several kinds:
1, at stainless steel coil of interior welds of pot cover, in order to support sealing ring to guarantee and the sealing of interior pot that this kind structure exists following deficiency: solder joint influences outward appearance, cost is high and clean difficulty;
2, increase a metal inner cover plate, fix at the Zhou Zhouyu of inner cover plate sealing ring, the cost of this kind fixed form is high, increases manufacturing cost, when unpicking and washing, need inner cover plate be taken cleaning simultaneously, uses inconvenient;
3, on pot cover towards convex closure, increase a plastic stent simultaneously, through cooperating of convex closure and plastic stent forming interference fit, plastic stent fixed seal ring; Plastic stent directly contacts with food, to plastic material selected the food hygiene requirement for use, have the too high problem of cost equally, and plastic stent is yielding in the back that is heated;
4, pot mouth sealing ring and metal inner cap manufacture single component; Normally the pot mouth sealing ring is placed between metal inner cap and the plastic ring; Fix through screw or rivet, this scheme need be pulled down cleaning with whole assembly in the process of unpicking and washing; Sealing ring cannot be pulled down cleaning separately, gives to make and has brought certain inconvenience sometimes;
5, sealing ring passes through interference fit in the groove of inner cap; Perhaps parts such as sealing ring and cover plate being dressed up assembly through set screws, is main with Japan and Korea S's product, and this scheme sealing ring can not be dismantled separately equally; When cleaning, there is the too high deficiency of inconvenience and cost equally.
Summary of the invention
The purpose of the utility model is in order to address the above problem, the pressure cooker hermetically-sealed construction that the utility model provides a kind of anti-seal circle to come off, and its sealing ring is without any need for the annex support member.The utility model processing technology is simple, and low cost is easy to use, can prevent effectively that sealing ring from coming off.
The purpose of the utility model is achieved in that the pressure cooker hermetically-sealed construction that a kind of anti-seal circle comes off; Include pot cover and sealing ring; Said pot cover is provided with at least two ladder planes, upwards is divided into first ladder and second ladder successively by the pot cover bottom, it is characterized in that; On the sidewall of pot cover second ladder, be distributed with some open slots or protruding to the inside convex closure; Corresponding therewith, be distributed with some convex closures or groove, the dismountable flexible connection of the mutual chimeric formation of convex closure on the open slot on the pot cover and the convex closure of sealing ring or the pot cover and the groove on the sealing ring in the said sealing ring outside.
The height of above-mentioned pot cover bottom to first cascaded surface is that the height of H1, first cascaded surface to the second cascaded surface is that H2, pot cover bottom to the height of directly stretching limit and cambered surface intersection, pot cover top are H3; 13.6≤H1≤17.5mm wherein, 10.3≤H2≤28.6mm, 40≤H3≤45mm.
Convex closure on open slot on the above-mentioned pot cover and the convex closure of sealing ring or the pot cover is connected through back-off or interference fit with the groove on the sealing ring each other.
The technical conceive of the utility model is: be suitable for the position that seal ring of pressure cooker is installed most; On pot cover, be provided with groove or convex closure; On sealing ring, be provided with simultaneously corresponding convex closure or groove; Pot cover and sealing ring assemble and farthest cost are reduced, and improve the sealing property of product simultaneously.
The utility model contrasts its beneficial effect of prior art, and the groove of pot cover or convex closure cooperate with the convex closure or the groove of sealing ring, and disassembly, cleaning easily simultaneously with the sealing ring support cancellation of prior art, have reduced the manufacturing cost of pressure cooker to a certain extent.
Description of drawings
Fig. 1 is the physical dimension sketch map of the utility model pot cover;
Fig. 2 is the structural representation of the utility model embodiment 1;
Fig. 3 is the structural representation of the utility model embodiment 2.
The specific embodiment
Below in conjunction with the Figure of description and the specific embodiment the utility model is further described.
Embodiment 1:
Like Fig. 1, shown in Figure 2; Present embodiment includes pot cover 1 and sealing ring 2, and said pot cover 1 is provided with at least two ladder planes, upwards is divided into first ladder 11 and second ladder 12 successively by pot cover 1 bottom; On the sidewall of pot cover second ladder 12, be evenly distributed with 6 open slots 3; Corresponding therewith, be evenly distributed with 6 convex closures 5 in said sealing ring 2 outsides, the open slot 3 on the pot cover forms dismountable flexible connection with the convex closure 5 of sealing ring is corresponding one by one through interference fit.Sealing ring difficult drop-off through interference fit is installed when the needs disassembly, cleaning, because big deformation can take place sealing ring 2, firmly pulls promptly capable of washing.As shown in Figure 1, the height of above-mentioned pot cover bottom to first cascaded surface 111 is that the height of H1, first cascaded surface, 111 to second cascaded surfaces 121 is that H2, pot cover bottom to the height of directly stretching limit and cambered surface intersection, pot cover top 13 are H3; In the present embodiment, the height of H1 is 14mm, and the height of H2 is 24mm, and the height of H3 is 42mm.
Embodiment 2
As shown in Figure 3; The difference of present embodiment and embodiment 1 is, is provided with 6 protruding to the inside convex closures 4 at pot cover 1, is provided with 6 grooves 6 in the relevant position in sealing ring 2 outsides simultaneously; The convex closure 4 of pot cover 1 and groove 6 interference fit of sealing ring 2 form dismountable flexible connection.
In the present embodiment, the height of H1 is 17mm, and the height of H2 is 28mm, and the height of H3 is 42mm.
The above only is the preferred embodiment of the utility model, is not that the structure of the utility model is done any type of restriction.Every technical spirit according to the utility model is to any simple modification that above embodiment did, and equivalent variations and modification all fall in the protection domain of the utility model.
