Description

Oven with grill

Technical Field

The utility model belongs to the technical field of the oven, concretely relates to oven with gridion.

Background

The oven is an electric heating appliance for baking food, and can be used for making roast chicken and roast duck, and can also be used for baking bread, cakes and the like. The oven has a sandwich structure comprising a casing with door, a heater and a grill, and a casing with a heat insulating cotton filled between the outer surface of the casing and the inner wall of the casing.

The grill in the existing oven is generally installed in an inner container, for example, the chinese utility model patent of the applicant's prior application "grill installation structure of electric oven" (patent No. CN201110306729.3, publication No. CN202179464U) discloses a grill installation structure of an electric oven, which comprises an inner container and a grill, wherein lateral supports are respectively fixed on the left and right inner walls of the inner container, the lateral supports comprise a base portion and a shelving strip fixed on the base portion and arranged along the front-back direction, the left and right ends of the grill are provided with shelving edges for shelving the shelving strip, and the front portion of the shelving strip is provided with a blocking portion which is arched upwards. Although this patent achieves a stop for the grill, the presence of the stop during actual pulling of the grill causes the food to slide off the grill due to inertia and potentially out of the grill, burning the user.

Therefore, like chinese utility model patent "an oven with gridion" (patent number is CN201821003618.3, and the publication number of granting is CN209018493U) that applicant applied earlier, disclose an oven with gridion, including the inner bag that has the front side opening and set up the gridion in the inner bag, both sides all have the limit of shelving about the gridion, all be provided with at least one on the two inside walls of left and right sides of inner bag and supply the corresponding gridion to shelve the portion of shelving that the limit was placed, should shelve the portion and extend along the fore-and-aft direction of inner bag, its characterized in that: a limiting structure for limiting the grill to be completely moved out from the inner container opening is arranged between the grill placing edge and the corresponding inner container placing part in a matched manner; and the front side of the grill is provided with a blocking piece higher than the bottom of the grill. The existence of the piece that stops in this patent prevents to a certain extent that food on the gridiron from sliding out the gridiron forward and scald the user, and in the relative inner bag of gridiron removal in-process, because have the frictional force between gridiron shelf edge and the inner bag supporting part, can't guarantee to act on the power of gridiron and maintain invariably, and under the circumstances that stops the rigid, at the power sudden increase of the backward push gridiron or the power sudden reduction of the forward pull gridiron of the force, food is because of inertia effect very big probably from the space between piece and gridiron and the relative gridiron of the upper portion of piece forward roll-off gri.

Accordingly, there is a need for further improvements to existing ovens having grills.
