Description
Technical field
The utility model belongs to a kind of fixture of pressure cooker, is specifically related to the anti-shrinking structure of a kind of electric cooker sidewall.
Background technology
Electric cooker generally includes a pot body, and with pot body chain connection and the free end upper cover that can mutually fasten, be provided with heating unit in pot body and can hold inner bag, pot body, upper cover junction are provided with sealing ring, are provided with row's bleed passage of various shape in pot cover.
Usually computer chip is embedded with in upper cover, upper lid surface is provided with the control panel controlling computer chip, when intelligence pot is started working, micro computer detects temperature and the upper cover sensor temperature of main temperature controller, when relevant temperature meets operating temperature range, connect electric hot tray power supply, electric hot tray powers on heating.Because electric hot tray fully contacts with inner bag, heat passes on inner bag very soon, inner bag passes to corresponding heat in meter He Shui, rice water starts heating, along with rice water heat temperature raising, moisture starts evaporation, upper cover sensor temperature raises, when micro computer detects that inner bag rice water seethes with excitement, the heating power of adjustment electric cooker, thus ensure that soup does not overflow, when after boiling a period of time, water in moisture evaporation and inner bag is blotted by meter Ji Ben, and the grain of rice bottom inner bag likely adheres to the bottom of a pan together with dextrin and forms a thermal insulation layer; Therefore, cooking bottom temperature can rise with fast speed, the temperature of corresponding main temperature controller also can rise with very fast temperature, limit Wen Wendu is reached when micro computer detects main temperature controller temperature, micro computer drives relay to disconnect electric hot tray power supply, electric hot tray power-off is not generated heat, and enters the state of cooking rice over a slow fire, and cooks rice over a slow fire after terminating and proceeds to keeping warm mode.
At present; entirety or the outer wall of the panel cover of electric cooker, upper cover, pot body all have plastic material to make; in order to improve aesthetic property and the streamline sense of assembling; plastic material can be tightened together by bonding usually; inner wall sets out horizontal connecting plate, is used for supporting bonded block and holding the glue bondd.And along with the increase of service time, horizontal connecting plate is easy to occur shrinking, thus electric cooker outer wall is caused to there will be the male and fomale(M&F) of uneven.This phenomenon not only can affect the aesthetic property of electric cooker, and very large impact also can be caused to the clean of electric cooker outer wall in rough surface, further, also can affect the bond strength at gummed position.
Summary of the invention
The utility model proposes for solving prior art Problems existing, its objective is and provides a kind of electric cooker sidewall anti-shrinking structure.
The technical solution of the utility model is: the anti-shrinking structure of a kind of electric cooker sidewall, the upper cover comprise a pot body, fastening with pot body, and the upper cover panel cover of gluing together, upper cover comprises cylindric sidewall, the lid of arc-shaped and the dowel both being connected, the upper wall of the inwall of sidewall, the outer wall of lid, dowel surrounds fitting recess, dowel comprises the left connecting portion be connected with sidewall, the right connecting portion be connected with lid and transition part, and the angle of sidewall and left connecting portion is acute angle.
Described transition part is fold-line-shaped or shaped form.
The transition part of described fold-line-shaped is convex broken line.
Described curved transition part is circular arc line or wave.
Described right connecting portion is parallel with sidewall.
Left connecting portion in described dowel, right connecting portion and transition part are formed in one.
Described dowel thickness is 1/4 to 1/2 of sidewall thickness.
The left connecting portion of the utility model the utility model by tilting to connect, reduce sidewall and receive the size of shrinking shearing stress, namely the stress intensity of diffusion method eliminating effect on left connecting portion is passed through by fold-line-shaped or curved connecting portion, also the distortion of sidewall is reduced by the plastic deformation of self, and by subtracting the material capability of thick and one-body molded increase dowel.

Detailed description of the invention
Below, with reference to drawings and Examples, the utility model is described in detail:
As shown in Figure 1, the anti-shrinking structure of a kind of electric cooker sidewall, the upper cover 2 comprise pot body 1, fastening with pot body 1, and upper cover 2 panel cover 3 of gluing together, upper cover 2 comprises cylindric sidewall 4, the lid 5 of arc-shaped and the dowel 10 both being connected, the upper wall of the inwall of sidewall 4, the outer wall of lid 5, dowel 10 surrounds fitting recess 6, and dowel 10 comprises the left connecting portion 7, the right connecting portion 8 be connected with lid 5 and the transition part 9 that are connected with sidewall 4.
Left connecting portion 7 tilts to be connected with sidewall 4, and sidewall 4 is acute angle with the angle of left connecting portion 7.When shrinking appears in dowel 10, making a concerted effort under sidewall 4 is subject to being tilted to, this can resolve into tension and shearing stress with joint efforts, a small amount of shearing stress is only had to make sidewall shrink, and this shearing stress can, by left connecting portion 7 and sidewall 4 angle of inclination, make it within the scope of sidewall 4 plastic deformation.Sidewall 4 and the angle of left connecting portion 7 are that acute angle can be avoided outside sidewall 4 due to convex-concave surface that contraction produces.
Described transition part 9 is fold-line-shaped or shaped form.By the method that structure spreads, eliminate the stress shrinking and produce, further avoid larger concentrated stress to act directly on the inner side of sidewall 4.
As shown in Figure 2, described curved transition part 9 is circular arc line or wave.By the circular arc that one or more is larger, eliminate concentrated stress.The non-reversible deformation of sidewall 4 is avoided by the distortion of multilevel hierarchy self.
As shown in Figure 3, the transition part 9 of described fold-line-shaped is convex broken line.By the plastic deformation of dowel 10 itself, eliminate concentrated stress.
Described right connecting portion 8 is parallel with sidewall 4.
Left connecting portion 7 in described dowel 10, right connecting portion 8 and transition part 9 are formed in one.Increase the fatigue strength of dowel 10 entirety.
Described dowel 10 thickness is 1/4 to 1/2 of sidewall 4 thickness.Reduce the contraction of dowel 10 through-thickness.
The left connecting portion of the utility model by tilting to connect, reduce sidewall and receive the size of shrinking shearing stress, namely the stress intensity of diffusion method eliminating effect on left connecting portion is passed through by fold-line-shaped or curved connecting portion, also the distortion of sidewall is reduced by the plastic deformation of self, and by subtracting the material capability of thick and one-body molded increase dowel.
