As shown in fig. 1 and 2, an embodiment of the present invention provides an oven 100, which includes a box body 10, a door body 20, and a door opening mechanism 30. Specifically, the door body 20 is pivotally connected at the cabinet 10 at a first edge, so that the door body 20 can be opened in a manner of being rotated with respect to the cabinet 10. The door opening mechanism 30 comprises a driving device 31 and a push rod 32, wherein the driving device 31 is in transmission connection with the push rod 32 to drive the push rod 32 to push and push a position on the door body 20 close to a second edge from the inner side of the door body 20, and the second edge is parallel to and opposite to the first edge.

According to the oven 100 provided by the embodiment of the invention, the door opening mechanism 30 is provided and comprises the driving device 31 and the push rod 32, wherein the driving device 31 is in transmission connection with the push rod 32, and the driving device 31 can drive the push rod 32 to push the door body 20 from the inner side of the door body 20, so that the door body 20 is opened. The opening process of the door body 20 can be completed by driving the push rod 32 through the driving device 31, so that a user does not need to directly touch the door body 20 with hands, and the problem that the user is scalded by the door body 20 possibly in the process of opening the door is solved.

In addition, the door body 20 is pivotally connected to the box body 10 at a first edge, and the push rod 32 of the door opening mechanism 30 pushes a position on the door body 20 close to a second edge, and the first edge and the second edge are two opposite edges of the door body 20, so that it can be ensured that a relatively maximum distance is formed between the force application point of the push rod 32 to the door body 20 and the rotation center of the door body 20 in the process of opening the door, so that the moment of opening the door has a relatively maximum moment arm, and thus, the push rod 32 can be opened without having a large push force, and the door body 20 can be opened, and further, the driving device 31 with a low push force requirement and a low power supply requirement can be selected, so as to save cost.

It is understood that the inner side of the door 20 refers to a side of the door 20 close to the cooking cavity (also referred to as an inner container) when the door 20 is closed.

For convenience of description, expressions indicating directions such as "front", "rear", "left", "right", and the like are used herein, and the expressions are understood as follows: for the oven 100, the side facing the user is the "front" side, and the opposite direction to the "front" is the "back"; "left" refers to the "left" side of the user when the user is standing in front of the oven 100 and facing the oven 100; similarly, reference to "right" in this embodiment refers to the right of the user when the user stands in front of the oven 100 and faces the oven 100.

In some embodiments of the present invention, the first edge of the door body 20 is a lower edge of the door body 20, and correspondingly, the second edge of the door body 20 is an upper edge of the door body 20. That is to say, the pivoted pivot is close to the lower limb setting of door body 20, and under this condition, in case door body 20 is pushed away by push rod 32, door body 20 produces the inclination for vertical direction promptly, and at this moment, the gravity of door body 20 self forms the moment of opening the door that makes door body 20 further open at the position of the focus of door body 20 for the angle of opening of door body 20 can expand by oneself, and need not the user and go to pulling door body 20 with the hand, not only makes the process of opening the door more laborsaving, has further avoided the scald risk moreover.

In some embodiments of the present invention, the oven 100 further includes an inner container 50 disposed inside the oven body 10, and the door opening mechanism 30 is disposed inside the oven body 10 and above the inner container 50. Since the main function of the door 20 is to be able to close the inner container 50, it can be known that the top of the door 20 is inevitably higher than the top of the inner container 50 in the vertical direction (otherwise, the inner container 50 cannot be strictly closed). Therefore, the door opening mechanism 30 can be disposed above the inner bag 50, and the purpose of bringing the urging position of the push rod 32 closer to the upper edge of the door body 20 can be achieved relatively easily.

Further, the number of the door opening mechanisms 30 can be set according to actual conditions, in general, one door opening mechanism 30 can meet the use requirement of door opening, and when only one door opening mechanism 30 is provided, the door opening mechanism can be arranged in the center of the box body 10 or arranged to the left or right relative to the box body 10. When the oven 100 has a large size in the left-right direction, two door opening mechanisms 30 may be provided, and the two door opening mechanisms 30 may be respectively provided to the left and right with respect to the oven body 10, so that the door body 20 is stressed in a balanced manner in the left-right direction.

In some embodiments of the present invention, as shown in fig. 3 to 7, the driving device 31 includes a motor 311, a screw 312 and a slider 313, wherein the screw 312 is connected to an output shaft of the motor 311, the slider 313 is engaged with the screw 312 through threads, and the push rod 32 is connected to the slider 313. In the present embodiment, the driving device 31 includes a motor 311, a screw 312 and a slider 313, when the motor 311 operates, the output shaft thereof drives the screw 312 to rotate, the rotation of the screw 312 is further converted into the linear motion of the slider 313, and the linear motion of the slider 313 forms the linear motion of the push rod 32 because the push rod 32 is connected with the slider 313. Therefore, the push rod 32 can be driven to move forwards to push the door body 20 by the forward operation of the motor 311, and the backward movement of the push rod 32 can be realized by the reverse operation of the motor 311, so that the push rod 32 is retracted. It is easy to understand that, in the case that the push rod 32 is retracted, the user can manually close the door 20, and the process of closing the door 20 is not interfered by the push rod 32.

In some embodiments of the present invention, the driving device 31 further includes a housing 314, a mounting space 315 is formed in the housing 314, the screw 312 is disposed in the mounting space 315, the slider 313 is slidably disposed in the mounting space 315, the motor 311 is fixedly connected to the housing 314, and an output shaft of the motor 311 extends into the mounting space 315. The provision of the housing 314 allows the respective portions of the drive device 31 to be integrated into a unitary structure, whereby the efficiency of assembly between the drive device 31 and the other portions of the door opening mechanism 30 can be effectively improved.

In some embodiments of the present invention, a threaded hole 3131 is formed on the sliding block 313, and the sliding block 313 is sleeved on the screw 312 and is engaged with the screw 312 through a thread on the threaded hole 3131. In this embodiment, the sliding block 313 is sleeved on the screw 312, so that the movement track of the sliding block 313 can be limited by the screw 312, that is, the sliding block 313 moves along the axial direction of the screw 312, and it is not necessary to specially provide a sliding rail for limiting the movement track of the sliding block 313.

In some embodiments of the present invention, the cross-section of the slider 313 and the cross-section of the mounting space 315 are matched polygons, so that the slider 313 is restricted to the mounting space 315 without a rotational degree of freedom. For example, the cross-section of the slider 313 and the cross-section of the installation space 315 are both quadrangular, or may be both triangular or pentagonal, without being limited thereto. It can be understood that the sliding block 313 is sleeved on the screw 312, and in the process of rotating the screw 312, if the sliding block 313 is expected to make a linear motion, it is first required to ensure that the sliding block 313 cannot rotate around the axis of the screw 312, otherwise the screw 312 may drive the sliding block 313 to rotate together. When the sliding block 313 rotates synchronously with the screw 312, the sliding block 313 does not move linearly. Therefore, a structure for restricting the rotational degree of freedom of the slider 313 is also required. In the present embodiment, the cross section of the slider 313 and the cross section of the mounting space 315 are both polygonal, so that the slider 313 is restricted to the mounting space 315 without a rotational degree of freedom, thereby ensuring that the rotational motion of the screw 312 can be converted into the linear motion of the slider 313.

In other embodiments of the present invention, the driving device 31 further includes a guide rod (not shown) disposed in the installation space 315, the guide rod is disposed parallel to the screw 312, and the sliding block 313 is slidably sleeved on the guide rod. In this embodiment, the sliding block 313 is sleeved on the screw 312 and also on the guide rod, so that the sliding block 313 does not have a rotational degree of freedom around the axis of the screw 312, and the rotational motion of the screw 312 can be converted into the linear motion of the sliding block 313.

In some embodiments of the present invention, the housing 314 includes a main body portion 3141 and a first end plate 3142 and a second end plate 3143 installed at both ends of the main body portion 314, and the housing 314, the first end plate 3142, and the second end plate 3143 surround the installation space 315. In addition, the motor 311 may be coupled to the second end plate 3143 by a motor bracket 316.

In some embodiments of the present invention, the door opening mechanism 30 further includes a mounting bracket 33, the driving device 31 is fixed on the mounting bracket 33, and the mounting bracket 33 is fixedly disposed inside the housing 10. The mounting bracket 33 may provide a mounting base for the various structures of the door opening mechanism 30, for example, the housing 314 may be mounted on the mounting bracket 33, thereby making the door opening mechanism 30 an integral, unitary structure. In the process of assembling the door opening mechanism 30 with the oven body 10 of the oven 100, only the mounting bracket 33 needs to be assembled with the oven body 10, so that the assembling efficiency of the door opening mechanism 30 with the oven body 10 can be effectively improved.

In some embodiments of the present invention, a buffer (not shown) is disposed at an end of the push rod 32, so that the push rod 32 contacts the door 20 through the buffer, and the buffer can absorb the collision energy by deforming itself, thereby protecting the door 20.

Further, the buffer member may be a rubber block or a silicone block, which plays a role of buffering by using its own elastic deformation, thereby preventing the push rod 32 from colliding with the door body 20.

In some embodiments of the present invention, the door opening mechanism 30 may further include a stroke switch (not shown in the drawings), which may be disposed on a moving path of the slider 313 moving forward, and configured to control the motor 311 to rotate reversely when the slider 313 moves forward to a predetermined position, so that the push rod 32 is automatically retracted. In this embodiment, when the motor 311 drives the push rod 32 to move forward by a certain stroke to push the door 20 open, the slider 313 triggers the travel switch, and at this time, the travel switch controls the motor 311 to rotate in the reverse direction, so as to drive the push rod 32 to move backward, thereby retracting the push rod 32. After the door body 20 is opened, the push rod 32 is automatically retracted, so that the door body 20 is not interfered by the push rod 32 when the user closes the door body 20 again after taking out the heated food. The user does not need to additionally perform an operation of retracting the push rod 32, thereby providing further convenience to the user.

In some embodiments of the present invention, the door 20 is connected to the chest 10 by a hinge device 40. Further, the hinge device 40 is preferably a hinge device provided with a damper, so that the rotational angular velocity of the door 20 is relatively small during the opening process, thereby obtaining the effect of gradually opening the door. Particularly, in the case where the hinge device 40 is disposed near the lower edge of the door 20, if the door 20 rotates too fast during the opening process, the door 20 may easily collide with the table top on which the oven 100 is placed, resulting in a risk of damage to the door 20. In this embodiment, the hinge device 40 is a hinge device equipped with a damper, which can ensure that the door 20 has the effect of slowly opening the door, so as to avoid the door 20 from colliding with the table top during the door opening process.

In some embodiments of the present invention, the oven is a handle-free embedded oven, that is, the door 20 of the oven is not provided with a handle, so that the product has a complete overall appearance plane, the overall space of the kitchen can be saved, the cleaning by the user is facilitated, and the protruding handle is prevented from colliding with the user.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
