Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
1 to Fig. 7 pot cover 100 for specifically describing the pressure cooker of embodiment according to a first aspect of the present invention below in conjunction with the accompanying drawings.
The pot cover 100 of pressure cooker according to embodiments of the present invention includes being in elliptoid pot cover body 10, and pot cover body 10 is molded by plate stamping, and the inner surface of pot cover body 10 has the convex tendon 20 being molded with the integrated punching of pot cover body 10.
In other words, the pot cover 100 of the pressure cooker is mainly made up of pot cover body 10, wherein, (left and right directions as shown in Figure 1) extends pot cover body 10 in the horizontal direction, pot cover body 10 can be processed by plate by a variety of stamping procedures, the shape of the pot cover body 10 obtained after processing substantially forms ellipse, and plate is in punch process, a part for the upper surface of plate is downwardly concaved forms multiple grooves with the upper surface in pot cover body 10, and in the downward projection of convex tendon 20 of lower surface (i.e. the side surface towards pot of pot cover body 10) formation of pot cover body 10, so as to the strength and stiffness for the pot cover body 10 for improving pressure cooker.Further, pot cover body 10 is provided with the connecting portion (not shown) connected suitable for the pot (not shown) of pressure cooker, convenient boiler-cover 100 and the connection of pot.
Furthermore, convex tendon 20 is integrally formed with pot cover body 10, and integrally formed structure can not only ensure the stability of the properity of pot cover 100, and conveniently it is molded, is simple to manufacture, so that the bulk strength and stability of the pot cover 100 of the pressure cooker are higher, assembling is more convenient, and the life-span is longer.
And the pot cover body 10 of the pot cover body of the pressure cooker in correlation technique and the pot cover 100 of the embodiment of the present invention is all formed as ellipse, and the two is processed by the sheet-metal press working of same thickness, unlike, multiple downward projection of convex tendons 20 have been stamped and formed out below the pot cover body 10 of the pressure cooker of the embodiment of the present invention.With the size in correlation technique is identical and pot cover body of pressure cooker that designed without convex tendon compared with, the pot cover 100 of the pressure cooker has more preferable strength and stiffness.
Thus, the pot cover 100 of pressure cooker according to embodiments of the present invention, pass through the downward projection of convex tendon 20 of the inner surface setting of the pot cover body 10 in pot cover 100, the structural strength and rigidity of the pot cover 100 of the pressure cooker can be improved, improve the bearing capacity of pot cover 100, extend the time that pot cover 100 works in the operating mode of HTHP, so as to improve the service life of pot cover 100, the pot cover 100 of the pressure cooker it is simple in construction, processing, it is easy to manufacture, structural strength, good rigidity, reliability are high, novel appearance, attractive in appearance.
In certain specific embodiments of the invention, convex tendon 20 is in oval ring-type, and the shape of convex tendon 20 is adapted with the shape of pot cover body 10.That is, the inner surface (towards a side surface of pot) of the pot cover body 10 of ellipse is provided with the convex tendon 20 of oval ring-type, the convex tendon 20 of the oval ring-type protrudes from the lower surface of pot cover body 10.Preferably, the center of the oval ring-type convex tendon 20 and the center superposition of pot cover body 10.Thus, by setting the convex tendon 20 of oval ring on pot cover body 10, be conducive to improving the structural strength or rigidity of the pot cover 100 of the pressure cooker, so as to improve the bearing capacity of pot cover 100, and then improve the service life of the pot cover 100 of pressure cooker.
The present invention other embodiments in, convex tendon 20 include it is multiple, each convex tendon 20 along pot cover body 10 short-axis direction extension and along the long axis direction of pot cover body 10 be distributed.
In other words, the lower surface of pot cover body 10 can extend provided with multiple length directions (fore-and-aft direction as shown in Figure 1) along pot cover body 10 convex tendon 20 arranged spaced apart, each convex tendon 20 along the width (left and right directions as shown in Figure 1) of pot cover body 10.Multiple convex tendons 20 are arranged on pot cover body 10 in an orderly manner, can improve the strength and stiffness of pot cover 100, so as to improve the service life of the pot cover 100 of pressure cooker.It is another to be in the scheme for setting multiple convex tendons 20 on pot cover body 10：Extend along its length the inner surface setting of pot cover body is multiple, and the convex tendon being distributed in the width direction.Relative to the technical scheme of this set convex tendon, in the technical scheme for the setting convex tendon 20 that the present embodiment is provided, the length of convex tendon 20 is shorter, therefore buckling strength is comparatively some larger, can preferably improve the intensity of pot cover body 10.
Preferably, according to one embodiment of present invention, at least one short axle by pot cover body 10 in convex tendon 20.Specifically, one in multiple convex tendons 20 is located at the middle part of pot cover body 10, and other convex tendons 20 are respectively relative to the symmetry axis of pot cover body 10 in the longitudinal direction and are symmetrical arranged.Thus, by setting multiple convex tendons 20 being arranged symmetrically on pot cover body 10, the structural strength and rigidity of the pot cover 100 of the pressure cooker can be both improved, so as to improve the service life of pot cover 100, the cosmetic look of pot cover 100 can be increased again, Experience of Aesthetic Feeling is visually given.It is worth noting that, described in the present embodiment, at least one short axle by pot cover body 10 in convex tendon 20, the situation that short axle not only including this convex tendon 20 and pot cover body 10 is completely superposed, also include the situation that this convex tendon 20 is overlapped with the stub portion of pot cover body 10, but in general, the circle centre position at middle part, i.e. pot cover body 10 that this convex tendon can be Jing Guo the short axle of pot cover body 10.The convex tendon that this passes through the short axle of pot cover body 10 is highly effective to the intensity for improving the central area of pot cover body 10.
Advantageously, from the center of pot cover body 10 to the longitudinal end of pot cover body 10, the development length of convex tendon 20 is gradually reduced.That is, the length of the convex tendon 20 positioned at middle part of pot cover body 10 is more than the length of the convex tendon 20 positioned at both sides.The shape of the convex tendon 20 is adapted to length dimension with the shape and size of pot cover body 10, so as to lift structural strength, rigidity and the good appearance of the pot cover 100 of the pressure cooker.
