Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In order to solve the problems that the inner pot of the electric pressure cooker in the prior art is regularly taken from the outer pot, and the inner pot and the heat preservation cover can rub to cause the abrasion of the inner pot and the heat preservation cover to generate a rusting phenomenon, the structural strength of the inner pot and the heat preservation cover is reduced, and the service life of the electric pressure cooker is shortened, the utility model provides a cooking appliance; it should be noted that the cooking appliance of the present application includes an electric pressure cooker or an electric rice cooker, but is not limited to both, and the illustrated embodiment of the present application takes an electric pressure cooker as an example.

As shown in fig. 1 to 4, the cooking appliance includes a pot body 100, the pot body 100 includes a pot body 10 and an inner pot 20, wherein the pot body 10 includes a casing 11, a middle plate 12 and a heat-insulating cover 13, the middle plate 12 is disposed on the casing 11, the heat-insulating cover 13 is disposed in the casing 11 and below the middle plate 12, the heat-insulating cover 13 and the middle plate 12 jointly enclose a containing cavity 101, and the inner pot 20 is disposed in the containing cavity 101; the middle plate 12 includes an outer longitudinal ring plate 121, a transverse ring plate 122 and an inner longitudinal ring plate 123 which are connected, wherein the outer longitudinal ring plate 121 is connected with the housing 11, the heat-insulating cover 13 is located below the inner longitudinal ring plate 123 and encloses an accommodating cavity 101 together with the inner longitudinal ring plate 123, at least one guide protrusion 124 is convexly arranged on an inner wall surface of the inner longitudinal ring plate 123 facing the accommodating cavity 101, and the guide protrusion 124 protrudes out of the inner wall surface of the heat-insulating cover 13.

At least one guide projection 124 is arranged on the inner wall surface of the inner longitudinal ring plate 123 of the middle plate 12 facing the accommodating cavity 101 in a protruding mode, and the guide projection 124 protrudes out of the inner wall surface of the heat insulation cover 13. Like this, when the user gets interior pot 20 from pot body 10 and puts, interior pot 20 at first can contact with guide protrusion 124, area of contact between them is very little, consequently pot 20 and heat preservation cover 13 take place the large tracts of land friction between the metal in can effectively avoiding in the setting of guide protrusion 124, the long-term friction of interior pot 20 or heat preservation cover 13 has been prevented reliably and has appeared the wearing and tearing phenomenon, guaranteed that structural strength between them can not receive the influence, also guaranteed simultaneously that cooking utensil has long enough life, has promoted cooking utensil's practicality widely.

Alternatively, the contact surface 102 of the guide protrusion 124 facing the receiving cavity 101 is a smoothly curved surface. Therefore, when the inner pot 20 is taken out of the accommodating cavity 101 or placed in the accommodating cavity 101, the guide protrusion 124 is in contact with the inner pot 20 to play a role in guiding the inner pot 20, and the contact surface 102 of the guide protrusion 124 is a smooth curved surface, so that the friction between the contact surface and the inner pot 20 can be further reduced, and the inner pot 20 and the heat-preservation cover 13 are protected.

In the illustrated alternative embodiment of the present application, the contact surface 102 is a part surface of a sphere. Therefore, the forming process and the manufacturing of the guide protrusion 124 are facilitated, and the aesthetic appearance of the pot body 100 is improved.

Of course, in an alternative embodiment of the present application, not shown, the contact surface 102 is a circular arc surface extending in the axial direction of the pan body 100. The guide protrusion 124 with this structure can also guide the inner pan 20 when the inner pan 20 is taken out of the receiving cavity 101 or put into the receiving cavity 101.

As shown in fig. 4, the guiding protrusion 124 is located at the bottom edge of the inner longitudinal ring plate 123, and a surface of the guiding protrusion 124 facing away from the accommodating cavity 101 is bent to form a step structure 125, and the guiding protrusion 124 is supported on the heat-insulating cover 13 through the step structure 125. In this way, the structural strength of the position where the guide protrusion 124 is disposed at the bottom edge of the inner longitudinal ring plate 123 is significantly enhanced, that is, the guide protrusion 124 plays a role of enhancing the structural strength of the middle plate 12, and the compactness and stability of the connection between the middle plate 12 and the heat-insulating cover 13 are ensured.

As shown in FIG. 4, the top end of the heat-insulating cover 13 is bent to form a flange structure 131, and the step structure 125 is in contact fit with the flange structure 131. Thus, the contact cooperation of the flanging structure 131 and the step structure 125 effectively increases the contact area between the middle plate 12 and the heat-insulating cover 13, ensures the structural stability of the assembly of the middle plate and the heat-insulating cover, and effectively improves the quality of the cooking utensil.

Optionally, the heat-insulating cover 13 is formed by winding a metal plate, and the thickness of the heat-insulating cover 13 is smaller than the length of the radial section of the stepped structure 125, and the thickness of the heat-insulating cover 13 is greater than or equal to 0.3mm and less than or equal to 1 mm. The heat preservation cover 13 with the structure is convenient to process and manufacture, the heat preservation cover 13 is attached to the axial section of the step structure 125, and therefore the guide protrusion 124 plays a role in radially supporting the heat preservation cover 13, the heat preservation cover 13 is effectively prevented from deforming, and the product quality of a cooking appliance is improved.

Alternatively, the maximum distance between the contact surface 102 of the guide projection 124 facing the accommodation chamber 101 and the inner wall surface of the heat-retaining cover 13 is equal to or greater than 1mm and equal to or less than 6 mm. Through optimizing the size of guide bulge 124, both avoided guide bulge 124 the size too big and occupy too much chamber 101 that holds to ensure that the space that holds chamber 101 is by make full use of, can make guide bulge 124 play the guard action to the internal face of heat preservation cover 13 effectively again, with the practicality that improves cooking utensil.

Alternatively, the guide protrusion 124 is plural, and the plural guide protrusions 124 are provided at intervals around the circumference of the inner longitudinal ring plate 123. Therefore, the circumferential direction of the whole heat preservation cover 13 is effectively protected, and the product performance of the cooking utensil is further improved.

Preferably, the number of the guide protrusions 124 is 2 or more and 10 or less. The optimization of the number of the guide protrusions 124 can not only avoid the influence of too many guide protrusions 124 on the processing and manufacturing cost and the processing and manufacturing difficulty of the middle plate 12, but also avoid the problem that too few guide protrusions 124 cannot play an effective protection role on the heat-insulating cover 13.

Alternatively, the guide protrusion 124 is integrally injection molded with the inner longitudinal ring plate 123. Therefore, the processing and manufacturing cost of the cooking utensil is greatly reduced, and the economical efficiency of the cooking utensil is improved.
