The door structure 100 may be installed at an opening side of the case 200, and the door structure 100 may be rotatable with respect to the case 200 to open or close the case 200. The limiting part 201 may also be disposed at one side of the opening of the case 200, where the limiting part 201 may be matched with the door structure 100 to limit the door structure 100 from being opened or closed relative to the case 200, so as to avoid the influence on the cooking effect of the cooking appliance 1000 caused by the random opening of the door structure 100 during the cooking process, or even the damage to the user caused by the false opening.

Referring to fig. 2-6, a door structure 100 according to an embodiment of the present application includes a door 10, a clamping member 20, and a switch member 23. The door 10 is connected to the case 200 in a openable and closable manner. The clamping piece 20 is arranged on the door body 10. The switch 23 can drive the clamping member 20 to move between a first position a and a second position B relative to the door body 10.

The switch member 23 is formed by a portion of the locking member 20 protruding outside the door body 10, and when the locking member 20 is at the first position a, the locking member 20 is locked on the limiting portion 201, and when the locking member 20 is at the second position B, the locking member 20 is disengaged from the limiting portion 201.

In the door body structure 100 and the cooking electric appliance 1000 according to the embodiment of the present application, the clamping member 20 can slide between the first position a and the second position B relative to the door body 10, and the switch member 23 is fixedly connected to the clamping member 20 and protrudes outside the door body 10. So, the user can drive the joint piece 20 to slide through pushing the switch piece 23 in order to control the joint cooperation between joint piece 20 and the spacing portion 201 to avoid collision and produce great sound between joint piece 20 and spacing portion 201 at the switch door in-process, easy operation is convenient and effectively reduced the noise when opening and shutting the door, reinforcing user's use experience.

Specifically, the door 10 may be mounted at an opening side of the case 200 of the cooking appliance 1000, and the door 10 may be rotatably coupled to the case 200 by folding or otherwise such that the door 10 can be opened or closed with respect to the case 200. In some other embodiments, the door 10 may also be slidably disposed with respect to the case 200 to enable opening and closing, for example, the case 200 is provided with a sliding rail, and the door 10 slides on the sliding rail to enable opening and closing of the case 200.

The shape of the door body 10 may be adapted to the shape of the opening of the case 200, and thus the door body 10 may enable the sealing of the case 200 to be better when being closed with respect to the case 200, and the cooking appliance 1000 may enable food to be cooked better. The connection mode of the door body 10 and the box body 200 and the specific shape of the door body 10 are not limited, and the door body can be selectively arranged according to actual situations.

The clamping member 20 may be disposed at a side of the door 10, and in particular may be disposed on a side opposite to a junction between the door 10 and the case 200. Of course, in some other embodiments, the fastening member 20 may be disposed on the top side or the bottom side of the door body 10, and the installation position of the fastening member 20 on the door body 10 is not limited in this application. The clamping piece 20 is mainly used for being matched with the limiting part 201 to lock the door body 10 when the door body 10 is closed, so that the door body 10 is prevented from being pulled apart by mistake in the cooking process, and the user is prevented from being injured.

The engaging member 20 is slidably mounted on the door body 10 via a sliding portion 21. The sliding portion 21 may be provided as a slider that is slidably provided with respect to the door body 10 by means of a pulley, a chute, or the like. The sliding portion 21 is slidable relative to the door body 10 between a first position a and a second position B, wherein the first position a is a position when the sliding portion 21 slides to the lower side, and the second position B is a position when the sliding portion 21 slides to the upper side, for example, the sliding portion 21 is slidable in the up-down direction relative to the door body 10; alternatively, the sliding portion 21 may be slidable in the left-right direction with respect to the door body 10, and the first position a may be a position where the sliding portion 21 slides to the left, and the second position B may be a position where the sliding portion 21 slides to the right. The sliding mode and the sliding direction between the sliding portion 21 and the door body 10 are not limited in the present application.

It will be appreciated that in some embodiments, the latch 20 may include a retaining structure 22, the retaining structure 22 being configured to cooperate with the stop 201 to limit the door 10. The retaining structure 22 may extend from the sliding portion 21 toward the inner side of the door body 10 and protrude from the inner surface of the door body 10, so that the sliding portion 21 can drive the retaining structure 22 to slide, so that the retaining structure 22 can be engaged with the limiting portion 201 when the door body 10 is relatively closed with the case 200. The sliding portion 21 may be provided with one holding structure 22, or may be provided with a plurality of holding structures 22, for example, two holding structures 22 are connected to the sliding portion 21 at intervals, and the plurality of holding structures 22 can make the restriction effect of the clamping member 20 on the door body 10 better.

Of course, in some other embodiments, the sliding portion 21 may be configured to drive the clamping structure 22 to perform a clamping fit with the limiting portion 201 by a cam, a knob, or the like, which is not limited in the manner that the sliding member drives the clamping structure 22 to move.

It will be appreciated that in some embodiments, a clamping hole into which the clamping structure 22 enters may be formed at a position of the case 200 opposite to the clamping member 20, and when the door 10 is closed relative to the case 200, the clamping structure 22 may extend into the clamping hole, so that the door 10 can be better sealed with the case 200 when being closed, so that the cooking appliance 1000 can have a better cooking effect.

The limiting portion 201 may be configured as a plate or a column structure, and the limiting portion 201 may be directly formed inside a clamping hole on the case 200, or the limiting portion 201 may be formed on a fixing frame, and fixed at the clamping hole through the fixing frame and extended from one side of the door 10 to the inner side of the case 200, so that when the clamping structure 22 extends into the clamping hole, the limiting portion 201 may be matched with the clamping structure 22 to limit the door 10.

The switch piece 23 can be arranged at one side of the sliding part 21 opposite to the clamping structure 22, the switch piece 23 extends from the sliding part 21 to the outer side of the door body 10 and protrudes out of the outer side surface of the door body 10, and then a user can push the switch piece 23 to control the sliding part 21, so that the user can push the sliding part 21 to slide between the first position A and the second position B more conveniently, and the clamping structure 22 is matched with the limiting part 201 in a clamping way.

The switch member 23 may be provided in a plate-like structure, and a pushing surface thereof contacting the hand may be provided in an arc-shaped surface, so that a user is more comfortable when pushing the switch member 23. In some embodiments, the pushing surface may also be provided with a frosted surface to enhance friction, preventing the user from slipping off the operating surface when pushing the switch member 23. The switch member 23, the clamping structure 22 and the sliding portion 21 can be integrally formed, so that the connection between the switch member 23, the clamping structure 22 and the sliding portion 21 is firmer, and damage caused when the switch member 23 is pushed and the clamping structure 22 and the limiting portion 201 are clamped is avoided.

As shown in fig. 5, when the door 10 is closed relative to the case 200, the switch member 23 may be pushed to slide the sliding portion 21 to the first position a, and the retaining structure 22 slides synchronously with the sliding portion 21, so that the retaining structure 22 can be retained at the limiting portion 201. At this time, when the user pulls the door body 10 outward, the door body 10 can be opened, but a large noise is generated to affect the work or rest of other persons.

As shown in fig. 6, when the user wants to open the case 200 after cooking, the user can push the switch member 23 to slide the sliding portion 21 to the second position B, the holding structure 22 also slides synchronously with the sliding portion 21, and the holding structure 22 can be separated from the limiting portion 201. At this time, the user pulls the door body 10 and can open the box 200, and the sliding of the sliding part 21 is controlled by pushing the switch piece 23, so that the door body 10 can be prevented from being collided between the clamping structure 22 and the limiting part 201 in the opening and closing process to generate larger sound, and further, the noise generated in the using process is effectively reduced, and the using experience of the user is improved.

In some embodiments, the latch 20 is capable of sliding in an up-down direction relative to the door 10, with the first position a being located below the second position B. In this way, the sliding portion 21 can slide relatively smoothly with respect to the door body 10, so as to better drive the clamping structure 22 to perform clamping engagement with the limiting portion 201. Correspondingly, the limiting part 201 can be arranged obliquely upwards, and when the sliding part 21 drives the clamping structure 22 to slide downwards, the limiting part 201 can be better matched with the clamping structure 22 in a clamping way.

Referring to fig. 5 and 6, in some embodiments, the door structure 100 further includes a restoring member 50, where the restoring member 50 connects the door 10 and the sliding portion 21, and the restoring member 50 is configured to provide a force to the sliding portion 21 to move in a direction from the second position B to the first position a.

In this way, the reset piece 50 has a pulling force to the sliding part 21 in the direction of the first position a, when no external force pushes the sliding part 21, the sliding part 21 can be always kept at the first position a, and then the clamping structure 22 can be better matched with the limiting part 201 in a clamping manner when the door body 10 is closed, so that the door body 10 is further prevented from being pulled open directly, and the safety is enhanced.

Specifically, the restoring member 50 may be a spring, a bungee cord, or the like having elasticity. One end of the reset piece 50 is connected to the sliding part 21, the other end of the reset piece 50 is fixed on the door body 10, and the reset piece 50 always has a certain pulling force on the sliding part 21, so that the sliding part 21 can always be kept at the first position A when no external force is pushed.

When the door 10 needs to be opened, the user needs to push the switch member 23 to overcome the elastic force of the reset member 50, so that the sliding portion 21 slides to the second position B, and then pulls the door 10, the door 10 is opened, and after the external force is removed, the sliding portion 21 slides back to the first position a under the pulling force of the reset member 50.

When the door 10 needs to be closed, the user also needs to push the switch member 23 to overcome the elastic force of the reset member 50 to slide the sliding portion 21 to the second position B and then push the door 10, and after the external force is removed, the reset member 50 can pull the sliding portion 21 to slide back to the first position a, and the user does not need to push the switch member 23 again to slide the sliding portion 21 back to the second position B. The sliding portion 21 can be held at the first position a under the pulling force of the restoring member 50.

When the sliding portion 21 is at the first position a, the retaining structure 22 can be directly separated from the limiting portion 201 under the action of external force, that is, the door body 10 can be pulled away under the action of external force. However, after the holding structure 22 is pushed up by the limiting portion 201, the sliding portion 21 immediately returns to the first position a due to the action of the reset element 50, so that the door body 10 is easy to collide with and generate a loud sound, and further the force of the reset element 50 is actively overcome when the door is opened, so that the generation of a loud sound in the door opening process can be avoided.

In some embodiments, the end of the retaining structure 22 opposite to the sliding portion 21 may be formed with a guiding surface, which is obliquely arranged for guiding the limiting portion 201 to slide into the retaining structure 22 when the door body 10 is closed. In this way, when the user closes the door body 10, the user can directly push the door body 10 to close, the guiding surface can guide the limiting portion 201 to directly slide to the limiting position of the clamping structure 22, and the sliding portion 21 can pull the sliding portion 21 to slide back to the first position a under the pulling force of the reset piece 50, so that the door body 10 is relatively closed.

Of course, in the manner that the user directly pushes the door body 10 to close and directly pulls the door body 10 open, since the clamping member 20 has no external force support, the clamping member 20 collides with the door body 10 to generate a sound under the action of the reset member 50, so that the door body 10 is prevented from being directly pushed to close or the door body 10 is prevented from being directly pulled open when silence is required, so that influence on other people is avoided.

In some embodiments, the switch 23, the sliding portion 21, and the retaining structure 22 may be provided as an integrally molded structure by injection molding or other means. So, the connection between the three is more firm in order to be able to better cooperate, avoid breaking the damage at the promotion in-process, increase of service life.

Referring to fig. 2-7, in some embodiments, the door body structure 100 further includes a door handle 30, the door handle 30 is fixed on the outer side of the door body 10, a receiving space 33 is defined between the door handle 30 and the door body 10, and the switch member 23 is at least partially received in the receiving space 33.

Thus, the door handle 30 is more convenient for a user to pull the door body 10, and the door handle 30 can also play a certain protection role on the switch piece 23 in the accommodating space 33 because the switch piece 23 protrudes out of the outer surface of the door body 10, so that the switch piece 23 is prevented from being hung and damaged.

Specifically, the door handle 30 may be disposed at an outer side of the door body 10 and away from a side of the door body 10 to which the case 200 is connected, and the door handle 30 may be vertically installed on the door body 10 or may be transversely installed on the door body 10. A Rong-woolen space is formed between the door handle 30 and the outer surface of the door body 10, and when a user pulls the door handle 30 by hand, fingers can extend into the accommodating space 33 so as to grasp the door handle 30, and the door body 10 is pulled more conveniently.

The switch member 23 protrudes from the outer surface of the door body 10 and is at least partially accommodated in the accommodating space 33. When a user opens the door, the user can push the switch piece 23 while grasping the door handle 30 to slide by hand, so that the sliding part 21 slides towards the second position B to drive the clamping hook 221 to separate from the limiting part 201, and then the door body 10 can be opened by pulling the door handle 30, so that the operation is simple and convenient, and meanwhile, the switch piece 23 can be protected. Correspondingly, when the door is closed, the switch piece 23 can be pushed back to the first position A conveniently to lock the door body 10.

Referring to fig. 2-7, in some embodiments, the door handle 30 includes an inner side 31 adjacent to the door body 10, an accommodating space 33 is defined between the inner side 31 and the door body 10, an accommodating groove 34 is formed in the inner side 31, the accommodating groove 34 is configured to be matched with the structure of the switch member 23, the switch member 23 is at least partially accommodated in the accommodating groove 34, and the switch member 23 can move in the accommodating groove 34.

In this way, the accommodating groove 34 can better protect the switch piece 23, the accommodating space can enable the user to hold the switch piece 23 more conveniently, and meanwhile, the switch piece 23 can be pushed more conveniently in the accommodating space of the user groove.

Specifically, the inner side 31 may be a side of the door handle 30 facing the outer surface of the door body 10, and the inner side 31 may extend outward from the outer surface of the door body 10 and form an accommodating space 33 with the outer surface. The accommodating groove 34 may be formed by recessing the inner side surface 31 in a direction opposite to the accommodating space 33, and the structure of the accommodating groove 34 may be adapted to the shape of the switch member 23, so that the switch member 23 may slide in the accommodating groove 34, and the accommodating groove 34 may better protect the switch member 23 and prevent the switch member 23 from being damaged by scraping.

In this way, the user can drive the movement of the clamping member 20 relative to the door body 10 by pushing the operating member 233, so that the operation mode is simpler and more convenient, and the force applied by the finger during the door opening process is facilitated.

Specifically, the receiving groove 34 may be formed at the connection portion of the grip surface 311 and the door body 10, the connection section 231 may be adapted to the shape of the connection portion of the door handle 30 and the door body 10, and the operation piece 233 may be movably disposed at the end portion of the connection section 231 remote from the sliding portion 21 and protruding from the grip surface 311.

It can be appreciated that the operation member 233 may be partially located in the accommodating groove 34 and partially located in the accommodating space 33, and a finger of a user may extend into the accommodating space 33 to press the operation member 233, so that the operation member 233 and the connection section 231 are slidably engaged, and further the clamping member 20 can be driven to move between the first position a and the second position B.

The operation direction of the operation member 233 may be perpendicular to the moving direction of the clamping member 20, that is, the direction in which the finger presses the operation member 233 may be perpendicular to the direction of the holding surface 311, so that the user may press the operation member 233 simultaneously when pulling the door body 10 outwards, so that the door body 10 is unlocked, and the unlocking manner is more convenient.

Alternatively, in other embodiments, the operation direction of the operation member 233 may be inclined with respect to the movement direction of the engaging member 20, that is, the direction in which the finger presses the operation member 233 may be from bottom to top or from top to bottom. The present application is not particularly limited in this regard, and may be selected according to user habits.

Referring to fig. 14-16, in some embodiments, a driving surface 2331 is formed at an end of the operating member 233 facing the connecting section 231, a driven surface 2311 is formed at an end of the connecting section 231 cooperating with the operating member 233, and contact surfaces of the driving surface 2331 and the driven surface 2311 are disposed to be inclined with respect to an operation direction of the operating member 233.

In this way, the driving surface 2331 and the driven surface 2311 cooperate with each other to drive the clamping member 20 to move between the first position a and the second position B, so that the door body 10 can be switched between locking and unlocking.

Specifically, when the operation member 233 is pressed toward the connection section 231, the driving surface 2331 may perform a certain guiding function, so that the driven surface 2311 may slide along the direction of the driving surface 2331, and the connection section 231 will move upward under the driving of the operation member 233, so as to drive the clamping member 20 to move upward, so that the hook 221 and the limiting portion 201 are unlocked.

The driving surface 2331 and the driven surface 2311 may be both planar, and thus the operation member 233 may be more smoothly pressed toward the grip surface 311, and the two may be better engaged with each other, so that the operation is smoother.

Of course, at least one of the driving surface 2331 and the driven surface 2311 may be curved. For example, the driving surface 2331 is a curved surface protruding toward the driven surface 2311 side, or the driven surface 2311 is a curved surface protruding toward the driving surface 2331 side, so that the driving surface 2311 and the driven surface 2311 can slide together with each other well, and the operation is smoother. The structures of the driving surface 2331 and the driven surface 2311 are not limited in this application.

Referring to fig. 2-6, in some embodiments, the door body structure 100 includes a sheath 40, where the sheath 40 is disposed between the switch member 23 and the door handle 30, and the sheath 40 abuts the door handle 30 when the sliding portion 21 is in the first position a or the second position B, and the sheath 40 is a shock absorbing material member.

In this way, when the user pushes the switch member 23 to move, the sheath 40 can reduce the collision sound between the switch member 23 and the door handle 30, and can prevent the switch member 23 from being damaged due to overlarge pushing force, thereby playing a certain role in protecting the switch member 23.

Specifically, the sheath 40 may be made of a rubber material, which has good flexibility and thus good vibration damping effect, and also has good sound absorption and thus good noise reduction effect. When a user uses the door handle in a quieter environment, the sheath 40 can effectively reduce the collision between the switch piece 23 and the door handle 30 and the collision sound generated during the collision in the process of pushing the switch piece 23 to open or close the door body 10, and the impact on other people can not be caused.

In some embodiments, a sealing element may be disposed between the door 10 and the case 200, where the sealing element may have a better sealing effect when the door 10 is closed relative to the case 200, and meanwhile, the sealing element may also have a noise reduction effect, so as to avoid a large sound generated by collision with the case 200 when the door 10 is closed.

In certain embodiments, the sheath 40 is disposed over the switch 23. In this way, the sheath 40 not only can play a role in damping and reducing noise, but also can make the user more comfortable when pushing the switch member 23.

Specifically, the shape of the sheath 40 may be adapted to the shape of the switch member 23, and the sheath 40 is sleeved on the switch member 23. When the user pushes the switch member 23, the sheath 40 can reduce the sound generated by collision with the door handle 30 when the switch member 23 is pushed into place, and can also play a better role in protecting the switch member 23.

Referring to fig. 5 and 6, in some embodiments, the sheath 40 extends obliquely upward from the door handle 30 toward the door body 10. Specifically, the pressing surface of the sheath 40 facing the accommodating space 33 may be inclined upward from the door handle 30 toward the door body 10. Thus, when the user pushes the switch member 23 by pressing the sheath 40, the pressing force can be decomposed into upward and outward forces under the inclined structure of the sheath 40, and then the door body 10 can be opened in a homeopathic manner when the switch member 23 is pressed to open the door, so that the door opening process is more convenient and the hand feeling is more comfortable when the door is pressed.

Of course, in other embodiments, the sheath 40 may be configured to extend obliquely downward from the door handle 30 toward the door body 10. Specifically, the pressing surface of the sheath 40 facing the accommodating space 33 may be inclined downward from the door handle 30 toward the door body 10. Thus, when the user presses the sheath 40 to push the switch member 23, the pressing force can be decomposed into upward and inward forces under the inclined structure of the sheath 40, and then the inward pushing force is provided when the switch member 23 is pressed to open the door, so that the hook 221 can be better separated from the limiting portion 201, and the condition that the hook 221 is clamped and difficult to press is avoided.

The inclination direction of the sheath 40 is not limited in this application, and may be selected according to actual conditions. Preferably, the sheath 40 extends obliquely upward from the door handle 30 to facilitate opening the door.

In some embodiments, the sheath 40 is shaped to be grasped by the hand of a user. For example, the sheath 40 includes a downward and upward concave adapting curved surface, and the shape of the adapting curved surface can be adapted to the shape of the finger, so that the user can feel more comfortable when pressing, and the user can avoid touching the hand.
