Wherein, first spacing portion and second spacing portion set up to two respectively, and are located the left and right sides of box 1 open-ended respectively.
Wherein, the first limiting part can be set as a first arc-shaped protrusion 111, and the second limiting part can be set as a second arc-shaped protrusion 22; when the door body 2 is opened, the second arc-shaped protrusion 22 is abutted against the lower end of the first arc-shaped protrusion 111 to lock the door body 2 in a first opening position relative to the opening of the case 1; when the handle 21 is pulled again under the action of external force, the second arc-shaped protrusion 22 can rotate along the first arc-shaped protrusion 111 to overcome the resistance of the first arc-shaped protrusion 111, the second arc-shaped protrusion 22 is separated from the first arc-shaped protrusion 111, the door body 2 is unlocked at the first opening position corresponding to the opening of the box body 1, the first arc-shaped protrusion 111 and the second arc-shaped protrusion 22 can not only play a blocking role when being abutted, but also can smoothly rotate mutually to separate when the handle 21 is pulled again to apply larger force.
On the basis of any one of the above schemes, as shown in fig. 5 to 7, this embodiment provides a specific implementation manner in which the door body 2 is hinged to the box body 1, two double-L-shaped hinge seats 4 are disposed between the box body 1 and the door body 2, and the two double-L-shaped hinge seats 4 are respectively located at two sides of the opening of the box body 1; each double-L hinge seat 4 includes an L-shaped hinge plate 41 hinged with the door body 2 and a fixing plate 42 perpendicular to the L-shaped hinge plate 41 and fixedly connected with the case body 1. The L-shaped hinge plate 41 includes a transverse plate and a longitudinal plate, one end of the transverse plate is hinged with the door body 2 through a pin 43, and the fixing plate 42 is arranged perpendicular to the longitudinal plate. The fixing plate 42 and the L-shaped hinge plate 41 are integrally formed, and the fixing plate 42 can be fixed on the case 1 by screws. Since the door body 2 and the case body 1 need to overcome the resistance of the first limiting component when being switched from the first open position to the second open position, and the double-L-shaped hinge seat 4 made of metal has a certain micro elasticity, the double-L-shaped hinge seat 4 can bear a certain deformation in the process of frequently opening and closing the door body 2.
As shown in fig. 5, 6, 7 and 11, the door body 2 is provided with a hinge groove 23 matched with the L-shaped hinge plate 41, and the L-shaped hinge plate 41 is rotatably arranged in the hinge groove 23 through a pin 43. The end of the L-shaped hinge plate 41 that is hinged to the hinge groove 23 and the hinge groove 23 may be provided in an arc shape.
The second limiting component comprises a first clamping part 231 arranged at the bottom of the hinge groove 23 and a second clamping part 411 arranged at the lower end of the L-shaped hinge plate 41, and the first clamping part 231 is clamped with the second clamping part 411 to lock the door body 2 at a second opening position opposite to the opening of the box body 1. In the second open position, the first clamping portion 231 abuts against the second clamping portion 411, so that the door body 2 is prevented from continuing to rotate downwards relative to the box body 1, the door body 2 is locked in the second open position relative to the opening of the box body 1, and the door body 2 is prevented from being impacted to the tabletop in the second open position.
On the basis of any one of the above schemes, a third limiting component for locking the door body 2 at a closing position relative to the opening of the box body 1 is further arranged between the box body 1 and the door body 2.
As shown in fig. 2, 8 and 10, the third limiting component includes a positioning slot 24 provided on the door body 2 and positioning columns 12 provided on the box body 1 in a manner of sliding up and down, the two positioning columns 12 and the two positioning slots 24 are respectively provided, and the two positioning columns 12 are respectively located at the left side and the right side of the opening of the box body 1, and each positioning column 12 is matched with the positioning slot 24 to lock the door body 2 in a closed position relative to the opening of the box body 1; an arc-shaped guide part 25 for sliding the positioning column 12 into or out of the positioning groove 24 is arranged at the opening of the positioning groove 24. During opening and closing of the door, the positioning post 12 may be inserted into the positioning groove 24 by self gravity, or the positioning head at the lower end of the positioning post 12 may be abutted against the positioning groove 24 by spring force. The arc-shaped guide portion 25 enables the positioning column 12 to smoothly slide into or out of the positioning groove 24 in the process of opening and closing the door.
The following is further explained in connection with the working principle:
when the door opening and closing limiting device on the cooking appliance provided by the embodiment is used, after food cooking is finished, a user can lightly pull the handle 21 to switch the door body 2 from the closed position to the first open position, in the process, the second arc-shaped protrusion 22 slides along the guide groove 11 and slides from the lower end of the guide groove 11 to the upper end of the guide groove 11, the door body 2 is locked at the first open position opposite to the opening of the box body 1 by abutting against the first arc-shaped protrusion 111 at the upper end of the guide groove 11, and in the first open position, because an included angle between the door body 2 and the box body 1 is smaller (20-30 degrees), the door body 2 has a certain shielding effect on the opening of the box body 1, which is equivalent to adding a protection between a person and the opening of the box body 1, so that high-temperature steam and heat in the box body 1 can be prevented from scalding the person, and the high-temperature steam and heat in the box body 1 can be emitted from two sides to cool the inside the box body 1. When the user confirms that there is no risk, the handle 21 can be pulled again to switch the door body 2 from the first clamping open position to the second open position, so that the food in the box body 1 can be conveniently taken out.
The utility model is not limited to the above-mentioned alternative embodiments, on the premise of not contradicting each other, can combine arbitrarily between every scheme; any person who is in the light of the present utility model can obtain other products in various forms, however, any changes in shape or structure are within the scope of the present utility model as defined by the claims.
