[0051] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0052] Reference will be made below to Figures 1-8 Describe the door assembly of the cooking appliance according to the embodiment of the present application.

[0053] As Figures 1 to 3 shown, the cooking appliance 100 includes a main body 110, a door body 120, a door hook 130, a fastening member 140, a locking hook 150 and an operating part 160;

[0054] The main body 110 has a cooking cavity 111.

[0055] The main body 110 can be used to cook food through temperature control and time control. The cooking cavity 111 can cooperate with the door body 120 as a container to provide a closed environment for the food.

[0056] The door body 120 is pivotally mounted on the main body 110, so that the door body 120 can rotate a certain angle to open the cooking cavity 111, facilitating the operator to put the food to be heated into the cooking cavity 111. After the food to be heated is placed, the door body 120 can be rotated to close the cooking cavity 111, which can play the functions of heat preservation and heat insulation. At the same time, it can avoid scalding the operator during the process of heating the food, improving safety. In addition, a door handle 121 can be provided on the outer plate of the door body 120, and the door handle 121 can be used to facilitate the user to pull the door body 120. In some examples, a perspective window can also be provided on the door body 120 to facilitate observing the state of the food in the main body 110; in other examples, a control panel can also be provided on the door body 120 to control the operation of the electrical appliances in the main body 110.

[0057] The door hook 130 can be installed on the door body 120 and can extend from the back plate of the door body 120.

[0058] In daily use, when the door hook 130 extends from the back plate of the door body 120, impurities and dirt are not easily introduced into the door body 120, facilitating the cleaning work of the cooking appliance 100. The part of the door hook 130 extending from the back plate is used to engage with the engaging member 140, realizing the locking of the door body 120 relative to the main body 110. By setting the locking hook 150 to extend from the back plate of the door body 120, the door body 120 becomes more beautiful. Moreover, after the door body 120 is opened, there will be no protruding part on the side of the door body 120, avoiding accidental injury to the human body by the locking hook 150.

[0059] The engaging member 140 is pivotally mounted on the main body 110 and can be used to engage with the door hook 130.

[0060] During the actual cooking process, it is necessary to close the cooking cavity 111. By engaging the engaging member 140 with the door hook 130, the locking of the door body 120 to the main body 110 is realized, which is safe and reliable.

[0061] The locking hook 150 is rotatably mounted on the main body 110 of the cooking appliance 100 about a first axis between a first position and a second position. When the locking hook 150 is in the first position, it is adapted to lock with the fastening member 140. When the locking hook 150 is in the second position, it is adapted to unlock from the fastening member 140. When the fastening member 140 is unlocked and the door body 120 rotates in the door-opening direction, the door hook 130 is configured to drive the fastening member 140 to rotate in a direction away from the door hook 130.

[0062] By locking the fastening member 140 when the locking hook 150 is in the first position and driving the locking hook 150 to rotate from the first position to the second position, the first-stage unlocking of the cooking appliance 100 is achieved. By further operating the door body 120 to disengage the fastening member 140 from the door hook 130 and then pulling the door body 120, the door body 120 can be separated from the main body 110 of the cooking appliance 100 and opened. Two-stage unlocking operations are required to open the door body 120, which improves safety.

[0063] The locking hook 150 can be made of metal or plastic. For example, in some embodiments, the locking hook 150 is made of plastic, which may include, but is not limited to, PP (Polypropylene), POM (Polyformaldehyde), and PC (Polycarbonate).

[0064] The operating part 160 is connected to the locking hook 150 and is at least configured to drive the locking hook 150 to rotate from the first position to the second position.

[0065] Specifically, referring to Figure 1 , the operating part 160 extends outwards from the door body 120 for manual operation by a user. By manually controlling the operating part 160, the locking hook 150 is driven to rotate from the first position to the second position to achieve the first-stage unlocking of the cooking appliance 100. By further operating the door body 120 to disengage the fastening member 140 from the door hook 130 and then pulling the door body 120, the door body 120 can be separated from the main body 110 of the cooking appliance 100 and opened.

[0066] In actual operation, the user can put the food to be cooked into the cooking cavity 111. After the food is cooked, the user can apply a force to the operation part 160. The applied force can be pressure or tensile force, so that the locking hook 150 starts to rotate from the first position until the locking hook 150 rotates to reach the second position. At this time, the first lock of the cooking appliance 100 is released. At the same time, the user holds the door handle 121 and can pull the door body 120 outward with a relatively small force, so that the fastening part 140 is disengaged from the door hook 130. At this time, the door body 120 and the main body 110 of the cooking appliance 100 can also be unlocked accordingly. After the user opens the door body 120 and takes out the cooked food, after closing the door body 120, the fastening part 140 is engaged with the door hook 130, so that the door body 120 and the main body 110 of the cooking appliance 100 are locked again.

[0067] The cooking appliance 100 provided by the embodiment of the present application uses a double-layer lock design, which requires the user to complete a two-step unlocking to open the door, reducing the risk of children opening and touching the heated food and beverages and being scalded. At the same time, the overall structure of the child lock is simple, the operation is convenient and fast, and the cost is low, greatly improving the practicability and economy of the device.

[0068] It should be noted that the cooking appliance 100 may include but is not limited to a microwave oven, an oven or a steam oven, etc. For example, in some embodiments, as Figure 1 and Figure 2 shown, the cooking appliance 100 is a microwave oven.

[0069] In addition, the connection method between the operation part 160 and the locking hook 150 may include but is not limited to interference connection, pin shaft connection or bonding, etc. For example, in some embodiments, the connection method between the operation part 160 and the locking hook 150 is interference connection.

[0070] In actual operation, the operation part 160 can be at least partially exposed outside to facilitate the user's operation. When the food is cooked and the door body 120 needs to be opened to take out the food, at this time, the door body 120 is in the closed state and the locking hook 150 is located at the first position. The user can operate the operation part 160 to make the locking hook 150 rotate towards the second position until the locking hook 150 reaches the second position. At this time, the first lock of the cooking appliance 100 is released. At the same time, the user holds the door handle 121 and can pull the door body 120 outward with a relatively small force. With the release of the second lock, the door body 120 and the main body 110 of the cooking appliance 100 can also be unlocked accordingly.

[0071] In the related art, in order to prevent children from accidentally opening the door body, some cooking appliances are also provided with a child lock structure. The child lock structure is installed on the door body, and at least part of the child lock structure extends out of the side plate of the door body and is engaged with the main body of the cooking appliance. At the same time, the operation part of the child lock structure is arranged below the front plate of the door body.

[0072] However, in actual use, there are many drawbacks to the above solution: Since the above-mentioned child lock structure is located on the side plate of the door body, the side plate of the door body needs to be grooved for the child lock structure to protrude, making it extremely easy for impurities and dirt to enter the door body, increasing the difficulty of cleaning the cooking appliance; Secondly, the above-mentioned operation part is arranged on the front plate facing the user, and the height of the operation part is relatively low, so that children can easily touch the operation part, thus slightly weakening the protection effect of the child lock.

[0073] The cooking appliance 100 provided by the embodiment of the present application, through the settings of the above-mentioned lock hook 150 and operation part 160, adds a mechanical child lock structure on the basis of the original door opening system to ensure that before the door pulling action is completed, the child lock must be released first to complete the entire door opening action, preventing children from touching the heated food after opening the door body 120 and being scalded, and helping to improve the safety and reliability of the entire cooking appliance 100.

[0074] Refer to Figures 3 to 4 , the first axis direction is perpendicular to the pivot axis of the fastening member 140.

[0075] When driving the lock hook 150 to rotate, only need to rotate the operation part 160 around the first axis, so that the operation part 160 has no displacement in the first axis direction, which can reduce the volume of the main body 110 to a certain extent, making the cooking appliance 100 small and beautiful in volume.

[0076] Refer to Figure 1 and Figure 2 , the pivot axis of the door body 120 is located at the lower part of the main body 110, so that the door body 120 is arranged to open downward, the fastening member 140 is installed on the upper part of the side of the main body 110, the lock hook 150 is correspondingly arranged on the upper part of the side of the main body 110, and correspondingly, the operation part 160 is also located on the upper part of the side of the main body 110 for easy manual operation. At least part of the door hook 130 protrudes from the back plate of the door body 120.

[0077] In actual execution, since the pivot axis of the door body 120 is located at the lower part of the main body 110, and considering the user's door-opening force, the door handle 121 can be installed at a position on the door body 120 close to the upper part of the main body 110. Correspondingly, the fastening member 140 can be installed at the upper part of the side surface of the main body 110. When it is necessary to open the door body 120 to take out the food after the food cooking is completed, the user can rotate the operation part 160. The operation part 160 can drive the locking hook 150 to rotate around the first axis (i.e., the axis extending in the left-right direction) until the locking hook 150 rotates from the first position to the second position. At this time, the first lock of the cooking appliance 100 is released. At the same time, the user can hold the door handle 121 and can pull the door body 120 with a relatively small force. The upper end of the door body 120 can be separated from the main body 110 of the cooking appliance 100 and can rotate downward around the pivot axis. With the release of the second lock, the door body 120 and the main body 110 of the cooking appliance 100 can also be unlocked accordingly.

[0078] Secondly, since the operation part 160 needs to drive the locking hook 150, and the locking hook 150 can be adapted to unlock or lock the fastening member 140, therefore, the operation part 160 needs to be arranged adjacent to the fastening member 140. In the above embodiment, the fastening member 140 can be installed at the upper part of the side surface of the main body 110. Therefore, the operation part 160 is not directly facing the user, and the height of the operation part 160 is relatively high, making it difficult for children to easily reach the operation part 160, ensuring the safety of the child lock structure.

[0079] The cooking appliance 100 provided by the embodiment of the present application, through the above unlocking structure design of the downward-opening door, conforms to the human body's force application habit. The whole cooking appliance 100 occupies a relatively small space, improves the volume utilization rate, and is convenient for the overall layout. At the same time, the downward-opening door body 120 can be used to transfer the just-cooked hot food, facilitating the user to take and place the food, thereby optimizing the overall experience of the whole machine.

[0080] Refer to Figure 5 、 Figure 7 and Figure 8 , the locking hook 150 includes a mounting arm 151 and a hook body 152.

[0081] The mounting arm 151 is rotatably mounted on the main body 110 around the first axis, and the mounting arm 151 is connected to the operation part 160 on one side of the first axis.

[0082] When an external force is applied to the operation part 160, the external force applied to the operation part 160 includes pressure and tensile force. When the external force applied to the operation part 160 is pressure, the operation part 160 moves towards the main body 110, and the mounting arm 151 moves away from the main body 110 on the other side of the first axis. Or, when the external force applied to the operation part 160 is tensile force, the operation part 160 moves away from the main body 110, and the mounting arm 151 moves towards the main body 110 on the other side of the first axis. The structure is simple and easy to operate.

[0083] The hook body 152 is adapted to be locked and cooperated with the fastening part 140, and the hook body 152 is connected to the mounting arm 151 on the other side of the first axis.

[0084] Refer to Figure 5 , since the hook body 152 is connected to the mounting arm 151 on the other side of the first axis, the locking hook 150 will move synchronously with the mounting arm 151 on the other side of the first axis to lock or unlock the fastening part 140.

[0085] Refer to Figure 2 , the main body 110 includes an inner container 112, a mounting frame 113 and an outer cover 114.

[0086] Specifically, the inner container 112 has a cooking cavity 111, and the cooking cavity 111 can be used as a container to cooperate with the door body 120 to provide a closed environment for food.

[0087] The mounting frame 113 is mounted on the inner container 112, the fastening part 140 is pivotally mounted on the side of the mounting frame 113 away from the inner container 112, and the locking hook 150 is rotatably mounted on the side of the mounting frame 113 away from the main body 110.

[0088] In the embodiment of the present application, by mounting both the fastening part 140 and the locking hook 150 on the side of the mounting frame 113 away from the main body, the space required for mounting the fastening part 140 and the locking hook 150 along the extension direction of the pivot axis of the fastening part 140 is reduced to a certain extent, making the cooking appliance 100 have a compact structure and a small volume.

[0089] The outer cover 114 covers the outer of the inner container 112, and at least a part of the operation part 160 extends out of the outer cover 114.

[0090] Through the outer cover 114 covering the inner container 112, the protection of the inner container 112 is achieved. In addition, the outer cover 114 plays a role in heat insulation, preventing the heat of the inner container 112 from directly contacting the user and scalding the user. By making at least part of the operation part 160 protrude from the outer cover 114 for the convenience of the user to operate. When it is necessary to open the door body 120 to take out the food after the food cooking is completed, at this time the door body 120 is in the closed state and the locking hook 150 is in the first position. The user can operate the operation part 160 to make the locking hook 150 rotate towards the second position until the locking hook 150 reaches the second position. At this time, the first lock of the cooking appliance 100 is released. At the same time, the user holds the door handle 121 and can pull the door body 120 outwards with a relatively small force. With the release of the second lock, the door body 120 and the main body 110 of the cooking appliance 100 can also be unlocked accordingly.

[0091] Specifically, in one embodiment, the operation part 160 can be in contact with the locking hook 150. In other embodiments, the operation part 160 can also be integrally formed with the locking hook 150. The present application does not limit this.

[0092] Refer to Figure 4 , a flange 161 protruding outwards is provided on the outer peripheral wall of the operation part 160. The outer cover 114 is provided with an avoidance opening 115. The operation part 160 protrudes from the avoidance opening 115, facilitating the operator to operate and apply an external force to the operation part 160. The flange 161 is located inside the outer cover 114 and its size is larger than the size of the avoidance opening 115, so that the end face of the flange 161 can abut against the periphery of the avoidance opening 115 to realize the limit of the operation part 160 and prevent the operation part 160 from falling out of the avoidance opening 115.

[0093] The locking hook 150 has a guiding surface 153 extending obliquely. Through the setting of the guiding surface 153, when the engaging part 140 moves from the position of releasing the engagement with the door hook 130 to the position of engaging with the door hook 130, it is convenient for the engaging part 140 and the locking hook 150 to enter the locked state.

[0094] Refer to Figure 3 and Figure 6 , the engaging part 140 has a fork 141 with an upwardly open opening. The engaging opening of the door hook 130 is engaged with the fork 141. Since the opening of the fork 141 of the engaging part 140 is upwardly arranged, when it is necessary to release the engagement between the engaging opening of the door hook 130 and the fork 141, a downward force needs to be applied to the fork 141 to make the opening of the fork 141 rotate downwards. Usually, the door hook 130 is arranged to be connected to the door handle 121. Therefore, when opening the door, a downward force needs to be applied to the door handle 121. The operation is simple, conforms to the human body's force application habit, and improves the user experience.

[0095] The engaging part 140 has a pivoting part 142, a fork part 143 and a locking part 144.

[0096] The pivoting portion 142 is pivotally mounted on the main body 110.

[0097] Specifically, a pivot shaft 116 is provided on the main body 110. A boss 117 protrudes from the side wall of the pivot shaft 116. An installation hole 145 is provided on the pivoting portion 142. A guiding groove 146 axially penetrates the inner wall surface of the installation hole 145. During installation, the guiding groove 146 is aligned with the boss 117. The pivoting portion 142 is sleeved on the pivot shaft 116, and the pivoting portion 142 is slid close to the main body 110 so that the boss 117 protrudes from the guiding groove 146. The pivoting portion 142 is rotated so that the end face of the boss 117 facing the main body 110 abuts against the end face of the pivoting portion 142 facing away from the main body 110, and the boss 117 and the guiding groove are arranged staggered along the rotation direction of the locking hook 150, restricting the moving stroke of the pivoting portion 142 in the direction away from the main body 110 and preventing the pivoting portion 142 from falling off the pivot shaft 142. In addition, the boss 117 provides a predetermined rotational frictional force for the pivoting portion 142, enabling the pivoting portion 142 to be rotated by a predetermined external force magnitude and also to maintain its current angular position (i.e., the current position) after the external force is withdrawn.

[0098] The fork portion 143 and the locking portion 144 are both connected to the pivoting portion 142 and are spaced apart along the circumferential direction of the pivoting portion 142. The fork portion 143 is latched with the door hook 130, which can lock the door body 120 relative to the main body 110, that is, the second-stage lock of the above embodiment is locked. The locking portion 144 is locked with the locking hook 150, which can lock the pivoting portion 142, that is, the first-stage lock of the above embodiment is locked.

[0099] It should be noted that the locking portion 144 is formed with a locking surface 147 extending radially along the pivot shaft 116 of the pivoting portion 142. The locking surface 147 can abut against the locking hook 150, thereby locking the pivoting portion 142. Since the locking surface 147 extends radially along the pivot shaft 116, wear and deformation of the locking portion 144 caused by long-term locking and unlocking are avoided.

[0100] In some embodiments, the pivoting portion 142, the fork portion 143, and the locking portion 144 can be integrally provided.

[0101] Specifically, the locking portion 144 is provided with a locking groove, and the locking hook 150 is adapted to extend into the locking groove to lock with the fastening member 140. Thus, when it is necessary to open the door body 120 to take out the food after the food cooking is completed, the user can press the operating portion 160, and the operating portion 160 can drive the locking hook 150 to rotate around the first axis until the locking hook 150 rotates from the first position to the second position. At this time, the first lock of the cooking appliance 100 is released. At the same time, the user holds the door handle 121, and can pull the door body 120 with a relatively small force. The upper end of the door body 120 can be disengaged from the main body 110 of the cooking appliance 100 and can rotate downward around the pivot axis 116. With the release of the second lock, the unlocking between the door body 120 and the main body 110 of the cooking appliance 100 can also be correspondingly achieved.

[0102] It should be noted that the principle of the locking hook 150 cooperating with the locking groove to lock the fastening member 140 is that the locking groove is formed with a locking surface 147, and the locking hook 150 has a locking mating end surface 154. By making the locking surface 147 cooperate with the locking mating end surface 154, the locking of the fastening member 140 can be achieved. Specifically, there are various ways to form the locking surface 147. In the above embodiment, it is formed by the inner wall surface of the locking groove. Of course, in other embodiments, the locking portion 144 can also be a locking arm extending radially along the pivot axis 116, and the locking surface 147 is formed on the locking arm, so as to realize the cooperation between the locking mating end surface 154 of the locking hook 150 and the locking surface 147, and the locking of the fastening member 140 can be achieved. In addition, there are various forms of forming the locking surface 147, and the present application does not limit this.

[0103] In addition, there are various forms of forming the locking groove. For example, the locking portion 144 can be processed by punching.

[0104] In some embodiments, as Figure 4 and Figure 5 shown, the cooking appliance 100 can further include a first reset member 170.

[0105] The first reset member 170 can be elastically connected between the locking hook 150 and the main body 110, and the first reset member 170 can be used to drive the locking hook 150 to remain in the first position.

[0106] In order to prevent the first reset member 170 from being misaligned and affecting the reset effect, the main body 110 is provided with a connecting column. One end of the first reset member 170 can be connected to the connecting column, the other end of the first reset member 170 can be connected to the locking hook 150, and the first reset member 170 can be in a compressed state. The elastic restoring force of the reset member can drive the locking hook 150 to rotate to the first position. Of course, in other embodiments, the first reset member 170 can be in a stretched state, and the elastic restoring force of the reset member can drive the locking hook 150 to rotate to the first position.

[0107] Specifically, the first reset member 170 can be a spring or an elastic rubber sleeve, and there is no limitation here.

[0108] In actual execution, when the user presses the operation part 160, the locking hook 150 can rotate from the first position to the second position. During this process, the first reset member 170 located between the main body 110 and the locking hook 150 is continuously compressed, and the elastic force exerted by the first reset member 170 on the locking hook 150 continuously increases until the locking hook 150 overcomes the elastic force and rotates to the second position. At this time, the first lock of the cooking appliance 100 is released, and the user can pull the door handle 121 to pull the door body 120 downward, that is, unlock the second lock of the cooking appliance 100.

[0109] After opening the door, the user can release the operation part 160. After the manual force applied to the locking hook 150 to overcome the elastic force disappears, the locking hook 150 can rotate from the second position to the first position. During this process, the first reset member 170 located between the main body 110 and the locking hook 150 continuously elongates, and the elastic force exerted by the first reset member 170 on the locking hook 150 continuously decreases until the locking hook 150 returns to the first position, realizing the automatic reset of the locking hook 150, and the operation is simple.

[0110] In the cooking appliance 100 provided by the embodiment of the present application, through the above setting of the first reset member 170, the locking hook 150 can automatically return to the first position after the user releases the operation part 160. The connection column connection makes the first reset member 170 not easy to fall off and durable. At the same time, the structure is simple, the number of assembled parts is single, and the requirement for processing accuracy is low, which is beneficial to installation.

[0111] Of course, in other embodiments, the connection between the first reset member 170 and the main body 110 can also be provided with a hanging hole on the main body 110, and the first reset member 170 is connected to the main body 110 through the hanging hole.

[0112] Specifically, the type of the first reset member 170 can be selected according to the external force applied to the operation part 160. For example, in the embodiment of the present application, when the force applied to the operation part 160 is pressure, the first reset member 170 is selected as a tension spring. The operation part 160 is subjected to pressure, so that the locking hook 150 rotates from the first position to the second position. During this process, the first reset member 170 is stretched. When the external force applied to the operation part 160 is removed, the operation part 160 is reset to the first position under the action of the elastic force of the first reset member 170. In other embodiments, when the force applied to the operation part 160 is tension, the first reset member 170 is selected as a compression spring. The operation part 160 is subjected to tension, so that the locking hook 150 rotates from the first position to the second position. During this process, the first reset member 170 is compressed. When the external force applied to the operation part 160 is removed, the operation part 160 is reset to the first position under the action of the elastic force of the first reset member 170.

[0113] The cooking appliance 100 provided by the embodiment of the present application, in cooperation with the design of the first reset member 170, realizes the rotational unlocking and elastic reset of the locking hook 150. The first reset member 170 and the connecting column cooperate with each other, so that the mechanical properties of the locking hook 150 will not be greatly affected during the reciprocating motion, thereby increasing the reliability of the entire child lock structure.

[0114] Refer to Figure 1 , on the other side of the first axis, the mounting arm 151 further extends a connecting arm 155 towards the mounting bracket 113. The connecting arm 155 protrudes in the same direction as the hook body 152. In this way, to a certain extent, the space for mounting the first reset member 170 along the pivot axis direction of the fastening member 140 is reduced, making the main body 110 small and compact. In addition, the free end of the connecting arm 155 is bent for hook-fitting cooperation with one end of the tension spring. In this way, it is convenient to install the first reset member 170 and the operation is simple.

[0115] In some embodiments, refer to Figure 3 and Figure 6 , the cooking appliance 100 further includes a second reset member 180. The second reset member 180 is elastically connected between the fastening member 140 and the main body 110. When opening the door, the torques of the second reset member 180 and the door hook 130 on the fastening member 140 are opposite.

[0116] By providing the second reset member 180 connected between the fastening member 140 and the main body 110, when opening the door, the torques of the second reset member 180 and the door hook 130 on the fastening member 140 are opposite, so that after the external force acting on the door body 120 is removed, the door body 120 can automatically reset to the initial position under the action of the second reset member 180. The structure is simple and the operation is easy.

[0117] Specifically, the second reset member 180 may be a torsion spring. Of course, in other embodiments, the second reset member 180 can be selected as needed, and the present application does not limit this.
