Description

Oven with grill

Technical Field

The invention belongs to the technical field of ovens, and particularly relates to an oven with a grill.

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 previously applied for again, disclosed 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 left and right sides inside wall of inner bag and supply the corresponding gridion to shelve the limit of placing, should shelve the fore-and-aft direction extension of following inner bag, its characterized in that: a limiting structure for limiting the grill to be completely moved out of the inner container opening is arranged between the grill placing edge and the corresponding inner container placing edge in a matching manner; and the front side of the grill is provided with a blocking piece higher than the bottom of the grill. The existence of holding member in this patent, block food roll-off on the gridion to a certain extent and scald the user, when just beginning to promote, the gridion can be slowly steadily pushed in the inner bag, the food forward roll-off's possibility is little, fixed blocking rod can effectively prevent food forward roll-off, but when passing through limit structure, need make strength push gridion suddenly, food falls the more the possibility of gridion down because of inertia, fixed holding member is difficult to block food on the gridion, at this moment, food very big probably follows the space between holding member and the gridion and the relative gridion forward roll-off gridion in upper portion that holds member and drops.

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

Disclosure of Invention

The first technical problem to be solved by the present invention is to provide an oven with a grill which can effectively prevent food from sliding out of the grill forwards.

The second technical problem to be solved by the present invention is to provide an oven with a grill, which can realize the action of a blocking member without separately providing a power source.

The technical scheme adopted by the invention for solving the first technical problem is as follows: an oven with a grill comprises

The inner container is provided with a front side opening, and the left inner side wall and the right inner side wall of the inner container are respectively provided with a supporting part extending forwards and backwards;

the left side and the right side of the grill are placing sides used for placing on the corresponding side supporting parts, and the grill is arranged on the supporting part of the inner container in a way of moving back and forth under the driving of external force;

it is characterized by also comprising:

the blocking piece is arranged on the front side of the grill along the left-right direction and can be turned up and down relative to the grill, and at least part of the blocking piece is higher than the bottom of the grill when the blocking piece is turned up to the highest position;

and the power output end of the driving mechanism is in driving connection with the blocking piece and is used for driving the blocking piece to turn up and down relative to the grill.

The drive mechanism can be of various forms, but preferably, the drive mechanism comprises

A driving rod arranged to be movable back and forth with respect to the grill, a front end of which is drivingly connected to the blocking member, and which drives the blocking member to gradually turn upward to a highest position in a state where it is moved forward with respect to the grill, and to gradually turn downward to a lowest position in a state where it is moved backward with respect to the grill;

the elastic piece acts on the driving rod and always enables the driving piece to have the tendency of moving backwards relative to the grill when the elastic piece is in an energy storage state;

the power acting element is used for blocking the driving rod in the process that the grill retracts into the inner container, so that the driving rod moves forwards relative to the grill and reacts on the elastic element to enable the elastic element to gradually enter an energy storage state in the process that the grill continues to retract;

a locking structure for locking the grill completely retracted into the inner container;

the unlocking component acts on the locking structure and is used for unlocking the grill by the locking structure.

In order to facilitate the realization of the back and forth movement of the driving rod relative to the grill, a plurality of supporting rods which extend back and forth and are arranged at intervals left and right are arranged between the two placing edges of the grill, the supporting rods adjacent to the placing edges on the corresponding side are sleeves with open front ends and closed rear ends, the driving rod is inserted into the sleeve on the corresponding side, and the front end of the driving rod is exposed out of the opening at the front end of the sleeve.
