Description

Technical Field

[0001] This utility model specifically relates to an automatic door opening structure. Background Technology

[0002] A steam oven is a kitchen appliance that includes a cabinet that generates high temperatures to steam and bake food, and a door that can be rotated on one side of the cabinet. Usually, a handle is provided on the door to manually open or close the door relative to the cooking cabinet.

[0003] Compared to traditional electric ovens, electric steam ovens have an added steam system, thus enabling them to perform both baking and steaming functions simultaneously. They have become a hot topic in the research and manufacturing of kitchen appliances and an important component of modern kitchen appliances.

[0004] However, most electric ovens or electric steam ovens currently available, especially built-in electric steam ovens, have manually operated doors, resulting in low automation and a lack of technological appeal. Because of this manual door operation, users encounter several problems when using electric steam ovens. First, after steaming or baking, the oven door must be manually opened. Since the user is close to the oven and directly in front of it, the high-temperature steam can quickly escape, posing a risk of burns (to the face, hands, etc.). Second, because the oven door is connected by a hinge mechanism, it is difficult to control the force when manually pushing or pulling the door, potentially leading to injuries such as elbow collisions. Furthermore, excessive force when opening or closing the door can cause it to impact the oven body, vibrating dishes and splashing liquids. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide an automatic door opening structure that can open smoothly and improve safety.

[0006] An automatic door opening structure according to the present invention includes a fixed plate, a connecting rod rocker arm hinged to the fixed plate, a limit fixing bracket installed on the fixed plate, a straight rod provided on the limit fixing bracket, the straight rod passing through the limit fixing bracket, a first guide groove and a second guide groove respectively provided on the connecting rod rocker arm, a first sliding column provided in the second guide groove, one end of the first sliding column being connected to a push rod motor, and a second sliding column provided on the straight rod, the second sliding column being placed in the first guide groove.

[0007] Furthermore, the fixed plate is provided with a hinge plate, and the connecting rod rocker arm is connected to the hinge plate by a pivot screw.

[0008] Furthermore, it also includes a connecting rod fixing seat, which has a hollow position, and a portion of the connecting rod rocker arm is placed in the hollow position of the connecting rod fixing seat.

[0009] Furthermore, the straight rod is also provided with a first limiting stud and a second limiting stud, with the first limiting stud located on the left side of the limiting and fixing bracket and the second limiting stud located on the right side of the limiting and fixing bracket.

[0010] Furthermore, the fixed plate is also provided with a motor mounting base, and the push rod motor is fixed on the motor mounting base.

[0011] Specifically, the straight rod is parallel to the push rod motor.

[0012] The beneficial effects of this utility model are: this structure uses a push rod motor to drive the connecting rod rocker arm to swing, and the connecting rod rocker arm pushes the straight rod forward or backward, which can push the door to open or close smoothly, avoiding burns to the hands when opening the door by hand, thus improving safety; in addition, the connecting rod rocker arm is provided with a first guide groove and a second guide groove, which can provide more room for movement.

Detailed Implementation

[0018] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0019] The following is for reference. Figures 1 to 3According to an embodiment of the present invention, an automatic door opening structure includes a fixed plate 1, a connecting rod rocker arm 4 hinged to the fixed plate 1, a limiting fixing bracket 602 installed on the fixed plate 1, a straight rod 6 provided on the limiting fixing bracket 602, the straight rod 6 passing through the limiting fixing bracket 602, a first guide groove 401 and a second guide groove 402 respectively provided on the connecting rod rocker arm 4, a first sliding column 201 provided in the second guide groove 402, one end of the sliding column 201 being connected to a push rod motor 2, and a second sliding column 604 provided on the straight rod 6, the second sliding column 604 being placed in the first guide groove 401.

[0020] This structure uses a push rod motor 2 to drive a connecting rod rocker arm 4 to swing, and the connecting rod rocker arm 4 pushes the straight rod 6 forward or backward to smoothly open or close the door, avoiding burns to the hands when opening the door and improving safety; in addition, the connecting rod rocker arm 4 is provided with a first guide groove 401 and a second guide groove 402, which can provide more room for movement.

[0021] The fixed plate 1 of this structure is provided with a hinge plate 101, and the connecting rod rocker arm 4 is connected to the hinge plate 101 by a pivot screw 3. The connecting rod rocker arm 4 swings back and forth through the pivot screw 3; the fixed plate 1 and the hinge plate 101 are integrally formed. There is a space between the fixed plate 1 and the hinge plate 101, which allows the connecting rod rocker arm 4 to be placed in the space.

[0022] This structure also includes a connecting rod fixing seat 5, which has a hollow position, and a portion of the connecting rod rocker arm 4 is placed in the hollow position of the connecting rod fixing seat 5.

[0023] The straight rod 6 of this structure is also provided with a first limiting stud 601 and a second limiting stud 603. The first limiting stud 601 is located on the left side of the limiting and fixing bracket 602, and the second limiting stud 603 is located on the right side of the limiting and fixing bracket 602.

[0024] The fixed plate 1 of this structure is also provided with a motor mounting base 7, and the push rod motor 2 is fixed on the motor mounting base 7. The motor mounting base 7 is used to fix the position of the push rod motor 2. The motor mounting base 7 can be fixed to the fixed plate 1 by screws, or the motor mounting base 7 can be fixed to the fixed plate 1 by welding.

[0025] The connecting rod arm 4 of this structure is fixed to the fixed plate 1 by a pivot screw. The connecting rod arm 4 is rotatable. One end of the push rod motor 2 is fixed to the fixed plate 1, and the other end of the push rod motor 2 pushes the connecting rod arm 4 through the first sliding column 201, so that the connecting rod arm 4 can swing around the pivot screw 3 as the motor push rod 2 extends. The other end of the connecting rod arm 4 and the straight rod 6 are pushed back and forth through the second sliding column 604. The straight rod 6 is limited and fixed by the limiting bracket 602 to ensure that it only moves in one direction. The straight rod 6 is parallel to the push rod motor 2.

[0026] When the push rod of the push rod motor 2 is pushed out, the connecting rod arm 4 swings clockwise around the rotating shaft screw 3, thereby driving the straight rod 6 forward. When the front end of the straight rod 6 contacts the door, it pushes the door open.

[0027] When the second limiting stud 603 contacts the limiting fixing bracket 602, the straight rod 6 stops moving forward. The push rod motor 2 pushes the rod back, causing the connecting rod swing arm 4 to swing counterclockwise, and the straight rod 6 moves back. When the first limiting stud 601 contacts the limiting fixing bracket 602, the straight rod 6 stops moving and returns to its original position.

[0028] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
