Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of devices, systems, apparatuses, and methods consistent with aspects of the present application.

The cooking appliance according to an embodiment of the present application is an electric pressure cooker, including a pot body and a pot cover (not shown), as shown in fig. 1 and 2, the pot body includes a heat-insulating cover 1, an inner pot (not shown), a heating device 2 and an outer shell (not shown), the inner pot (not shown) is located in the heat-insulating cover 1, the outer shell (not shown) is located outside the heat-insulating cover 1, the heating device 2 is disposed between the bottom of the inner pot (not shown) and a bottom wall 11 of the heat-insulating cover 1, and the heating device 2 supports the inner pot upward for providing heat for the inner pot (not shown).

Referring to fig. 3 to 5, the pot body further comprises a plurality of elastic plates 3, and the elastic plates 3 are located between the heating device 2 and the bottom wall 11 of the heat-insulating cover 1. The elastic plate 3 is provided on the bottom wall 11 and elastically supports the heating means 2 upward. When the cooking utensil cooks, the inner pot (not shown) and the heating device 2 move downwards and press against the elastic plate 3 under the push of the high-pressure gas in the inner pot, and the elastic plate 3 transmits the pressure from the inner pot (not shown) to the bottom wall 11 of the heat-insulating cover 1. Because the elastic plate 3 has elasticity and can deform when being pressed, the elastic plate can counteract part of pressure from an inner pot (not shown), the heat preservation cover 1 is protected, and the pressure of the cooking appliance is adjusted and the safety protection is realized.

The bottom of the heating device 2 is provided with a plurality of connecting columns 21 extending downwards and used for being connected with the bottom wall 11 of the heat-preservation cover 1. The bottom wall 11 is provided with a plurality of supporting walls 12 for supporting the elastic plate 3, the connecting column 21 sequentially penetrates through the elastic plate 3 and the supporting walls 12, and the fastening piece 4 is upwards connected with the connecting column 21 from the bottom side of the bottom wall 11 so as to install the heating device 2 and the elastic plate 3 on the bottom wall 11. The connecting column 21 is located a distance down beyond the support wall 12 so that the fastening means 4 mounted to the underside of the connecting column 21 do not press up against the support wall 12. The extended design of the connecting column 21 avoids the problem that the fastener 4 is locked too tightly or too loosely due to the difference in height (caused by manufacturing tolerances) between the bottom surface of the connecting column 21 and the supporting wall 12 when the fastener 4 is pressed against the supporting wall 12 as an assembly reference, thereby affecting the service life of the fastener 4. Therefore, the cooking utensil of the present application can prolong the service life of the fastener 4 connecting the heating device 2 and the heat preservation cover 1 by adopting the prolonged connecting column 21.

The supporting wall 12 is provided with a through hole 121, the elastic plate 3 is correspondingly provided with a through hole 31, and the connecting column 21 passes through the through hole 31 and the through hole 121 to extend to the lower side of the supporting wall 12. The connecting column 21 is a conical cylinder with a large top and a small bottom, and the diameters of the through hole 121 and the through hole 31 are larger than that of the connecting column 21, so that the connecting column 21 is allowed to float up and down. The connecting column 21 is provided with an internal threaded hole 212, the fastener 4 is a screw, and the connecting column 21 is connected with the fastener 4 in a threaded connection mode, so that the connecting structure is simple and reliable. The fastener 4 is locked into the connecting column 21 from the bottom side, and the head of the fastener 4 is larger than the diameter of the through hole 121 and cannot enter the heat-insulating cover 1. The end 211 of the connecting column 21 is further sleeved with an elastic member 5, the upper end of the elastic member 5 upwards supports against the supporting wall 12, and the lower end downwards supports against the head of the fastener 4. The elastic piece 5 is tightly pressed against the fastening piece 4, so that the fastening piece 4 is prevented from being loosened due to spinning.

In the present embodiment, the length of the connecting column 21 beyond the supporting wall 12 is 3mm-10mm, which is too short to facilitate the assembly of the fastening member 4 and the installation of the elastic member 5, and is too long to easily touch the housing (not shown) at the bottom side of the heat-insulating cover 1.

In the present embodiment, three elastic plates 3 are provided in the pot body, and the number of the connecting columns 21 corresponds to the number of the elastic plates 3, and is also three. Be equipped with three protruding muscle 13 of evenly distributed on the diapire 11, protruding muscle 13 is along the radial extension of diapire 11, elastic plate 3 is the strip, place along the circumference of pot cover roughly, and elastic plate 3's middle section supports on protruding muscle 13, and the roof of protruding muscle 13 promptly is aforementioned support wall 12, and protruding muscle 13 has raised elastic plate 3 in other words, can make and form certain interval between two ends 32 of the elastic plate 3 of level form and the diapire 11, so that two ends 32 can downward elastic deformation.

The heating device 2 is further provided with a plurality of supporting columns 22, two sides of each connecting column 21 are respectively provided with one supporting column 22, and two end portions 32 of the elastic plate 3 respectively support the two supporting columns 22 of the heating device 2 upwards and elastically. That is, the elastic plate 3 supports the heating device 2 upward from both end portions 32 thereof, there is no supporting relationship between the connecting column 21 and the bottom wall 11, the length of the connecting column 21 does not affect the assembling position of the heating device 2, and the connecting column 21 can float up and down with a small margin together with the fastening member 4.

The bottom surface of support column 22 is equipped with boss 221, and the spacing mutual cooperation of boss 221 and the outward flange of elastic plate 3 can fix a position elastic plate 3, avoids elastic plate 3 horizontal rotation and breaks away from support column 22.

The middle part of the bottom wall 11 of the heat preservation cover 1 is provided with an annular platform 14 which protrudes upwards. The platform 14 is also stamped and formed, the top surface of the platform 14 is coplanar with the top surface of the rib 13, and the inner end of the rib 13 extends inwardly to connect with the platform 14. The heating device 2 is provided with a plurality of positioning columns 23 extending downwards, the platform 14 is provided with a plurality of positioning holes 141 for the positioning columns 23 to pass through, the heating device 2 and the heat preservation cover 1 can be positioned, and the heating device 2 can also provide a guiding function when moving.

The diapire 11 still is equipped with a plurality of convex strengthening ribs 15 that make progress, and strengthening rib 15 is connected with the outer end 131 of protruding muscle 13 for strengthen the intensity of protruding muscle 13, avoid the protruding muscle 13 compressive deformation of heat preservation cover 1, ensure the initial position of elastic plate 3, ensure that cooking utensil can normally work. The ribs 15 are located radially outside the ribs 13. The width of the reinforcing rib 15 is smaller than that of the convex rib 13, and the height of the reinforcing rib 15 is smaller than that of the convex rib 13, so that the punch forming is easier. The reinforcing ribs 15 are positioned at the connecting positions of the bottom wall 11 and the side walls 16 of the heat-preservation cover 1 and extend from the bottom wall 11 of the heat-preservation cover 1 to the side walls 16 of the heat-preservation cover 1, so that the reinforcing ribs 15 have high strength.
