[0053] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote 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 this application, and should not be construed as limiting this application.

[0054] The following is for reference. Figures 1-8 Describes the door 120 of a cooking appliance according to an embodiment of this application.

[0055] like Figures 1 to 3 As shown, the cooking appliance 100 includes a main unit 110, a door 120, a door hook 130, a fastener 140, a locking element 150, and an operating part 160;

[0056] The main unit 110 has a cooking cavity 111.

[0057] The main unit 110 can be used to cook food through temperature control and time control. The cooking cavity 111 can be used as a container to cooperate with the door 120 to provide a closed environment for the food.

[0058] The door 120 is pivotally mounted to the main unit 110, allowing it to rotate at a certain angle to open the cooking cavity 111. This facilitates the operator placing food to be heated into the cooking cavity 111. Once the food is in place, the door 120 can be rotated to close the cooking cavity 111, providing heat preservation and insulation while preventing burns to the operator during heating, thus improving safety. Additionally, a door handle 121 can be installed on the outer panel of the door 120 for easy pulling. In some examples, the door 120 may also have a viewing window to observe the food's condition inside the main unit 110; in other examples, a control panel may be installed on the door 120 to control the operation of the electrical components inside the main unit 110.

[0059] Door hook 130 can be installed on door body 120 and can extend from the back panel of door body 120.

[0060] In daily use, the door hook 130 extends from the back panel of the door 120, preventing impurities and dirt from easily entering the door 120, thus facilitating the cleaning of the cooking utensils 100. The portion of the door hook 130 extending from the back panel engages with the latch 140, enabling the door 120 to be locked relative to the main unit 110. By designing the latch 150 to extend from the back panel of the door 120, the door 120 becomes more aesthetically pleasing. Furthermore, when the door 120 is open, there are no protruding parts on the side of the door 120, preventing the latch 150 from accidentally injuring a person.

[0061] The fastener 140 is pivotally mounted on the main unit 110 about a first axis and can be used to fasten with the door hook 130.

[0062] In actual cooking, the cooking cavity 111 needs to be sealed. By engaging the fastener 140 with the door hook 130, the door 120 is locked to the main unit 110, which is safe and reliable.

[0063] Reference Figure 4 and Figure 6 The locking element 150 is pivotally mounted on the main unit 110 about a second axis. The first axis is parallel to the second axis. This avoids mutual interference between the locking element 150 and the latching element 140 during rotation and reduces the space required for arranging the locking element 150 and the latching element 140 on the main unit 110, making the cooking appliance 100 compact and aesthetically pleasing. The locking element 150 has a first position and a second position during its rotational stroke. In the first position, the locking element 150 is suitable for locking with the latching element 140. In the second position, the locking element 150 is suitable for unlocking with the latching element 140. When the latching element 140 is unlocked and the door 120 rotates in the opening direction, the door hook 130 drives the latching element 140 to rotate in the direction of disengagement from the door hook 130.

[0064] By locking the locking member 150 in the first position to lock the latching member 140, the locking member 150 is driven to rotate from the first position to the second position, thus achieving the first unlocking of the cooking appliance 100. Then, by operating the door 120 again, the latching member 140 is disengaged from the door hook 130. Only when the door 120 is pulled will the door 120 separate from the main unit 110 of the cooking appliance 100 and open. Opening the door 120 requires two unlocking operations, which improves security.

[0065] The locking element 150 can be made of metal or plastic. For example, in some embodiments, the locking element 150 is made of plastic, which may include, but is not limited to, PP (Polypropylene), POM (Polyformaldehyde), and PC (Polycarbonate).

[0066] The operating part 160 can be connected to the locking member 150 and is used to drive the locking member 150 to rotate from a first position to a second position.

[0067] Specifically, refer to Figure 1 ,and Figure 2 The operating part 160 extends outward from the door body 120 to facilitate manual operation. By manually controlling the operating part 160, the locking member 150 is driven to rotate from the first position to the second position, realizing the first unlocking of the cooking appliance 100. The door body 120 is operated again to disengage the latch 140 from the door hook 130. Only when the door body 120 is pulled will the door body 120 separate from the main body of the cooking appliance 100 and open.

[0068] In actual operation, the user can place the food to be cooked into the cooking cavity 111. After the food is cooked, the operator twists the operating part, causing the locking member 150 to rotate from the first position until the locking member 150 rotates 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 pulls the door 120 outward with a small force, causing the latch 140 to disengage from the door hook 130. At this time, the door 120 and the main unit 110 of the cooking appliance 100 can also be unlocked accordingly. After the user opens the door 120 and takes out the cooked food, after closing the door 120, the latch 140 and the door hook 130 are engaged, so that the door 120 and the main unit 110 of the cooking appliance 100 are locked again.

[0069] The cooking appliance 100 provided in this application embodiment utilizes a double-lock design, requiring the user to complete two steps to unlock the door, reducing the risk of children being burned when they open and come into contact with heated food and beverages; at the same time, the child lock has a simple overall structure, is easy and quick to operate, and is inexpensive, which greatly improves the practicality and economy of the device.

[0070] 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, for example, in some embodiments, such as Figure 1 and Figure 2 As shown, cooking appliance 100 is a microwave oven.

[0071] In addition, the connection between the operating part 160 and the locking member 150 may include, but is not limited to, interference fit, pin fit or bonding. For example, in some embodiments, the connection between the operating part 160 and the locking member 150 is an interference fit.

[0072] In actual operation, the operating part 160 can be at least partially exposed to the outside for easy user operation. When the food is cooked and the door 120 needs to be opened to take out the food, the door 120 is closed and the locking member 150 is in the first position. The user can operate the operating part 160 to rotate the locking member 150 toward the second position until the locking member 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 pulls the door 120 outward with a small force. With the release of the second lock, the door 120 and the main unit 110 of the cooking appliance 100 can also be unlocked accordingly.

[0073] In related technologies, to prevent children from accidentally opening the door, some cooking appliances are also equipped with a child lock structure. The child lock structure is installed on the door, and at least part of the child lock structure extends out of the side panel of the door and engages with the main unit of the cooking appliance. At the same time, the operating part of the child lock structure is located below the front panel of the door.

[0074] However, in practical applications, the above solution has many drawbacks: since the child lock structure is located on the side panel of the door, the side panel needs to be slotted to allow the child lock structure to extend, making it easy for impurities and dirt to enter the door, increasing the difficulty of cleaning cooking utensils; secondly, the operation part is located on the front panel facing the user, and the height of the operation part is low, making it easy for children to access the operation part, thus slightly weakening the protective effect of the child lock.

[0075] The cooking appliance 100 provided in this application embodiment, through the setting of the locking member 150 and the operating part 160, adds a mechanical child lock structure to the original door opening system to ensure that the child lock must be released before the door opening action is completed, so as to prevent children from touching the heated food after opening the door 120 and being burned, thus helping to improve the safety and reliability of the entire cooking appliance 100.

[0076] Reference Figure 2 The pivot axis of the door body 120 is located at the lower part of the main unit 110, so that the door body 120 is configured as a downward-opening door. The fastener 140 is installed on the upper side of the main unit 110, and the locking element 150 is correspondingly provided on the upper side of the main unit 110. Correspondingly, the operating part 160 is also located on the upper side of the main unit 110 for easy manual operation. At least a portion of the door hook 130 extends from the back panel of the door body 120.

[0077] In actual operation, since the pivot axis of the door 120 is located at the lower part of the main unit 110, and considering the user's opening force, the door handle 121 can be installed on the upper part of the door 120 near the main unit 110. The corresponding fastener 140 can be installed on the upper side of the main unit 110. When the food is cooked and the door 120 needs to be opened to take out the food, the user can rotate the operating part 160. The operating part 160 can drive the locking part 150 to rotate around the second axis until the locking part 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 pull the door 120 with a small force. The upper end of the door 120 can be separated from the main unit 110 of the cooking appliance 100 and can rotate downward around the pivot axis. With the release of the second lock, the door 120 and the main unit 110 of the cooking appliance 100 can also be unlocked accordingly.

[0078] Secondly, since the operating unit 160 needs to drive the locking member 150, and the locking member 150 can be adapted to unlock or lock the fastener 140, the operating unit 160 needs to be set adjacent to the fastener 140. In the above embodiment, the fastener 140 can be installed on the upper side of the main unit 110. Therefore, the operating unit 160 does not directly face the user, and the height of the operating unit 160 is relatively high, making it difficult for children to easily reach the operating unit 160, thus ensuring the safety of the child lock structure.

[0079] The cooking appliance 100 provided in this application embodiment, through the aforementioned bottom-opening door unlocking structure design, conforms to the human body's habit of applying external force. This makes the entire cooking appliance 100 occupy less space, improves volume utilization, and facilitates overall layout; at the same time, the pull-down door 120 can be used to transfer freshly cooked hot food, making it convenient for users to take and put away food, thereby optimizing the overall user experience.

[0080] Reference Figure 2 The main unit 110 includes an inner tube 112, a mounting bracket 113, and an outer cover 114.

[0081] Specifically, the inner liner 112 has a cooking cavity 111, which can be used as a container to cooperate with the door 120 to provide a closed environment for food.

[0082] Mounting bracket 113 is mounted on inner liner 112, fastener 140 is pivotally mounted on the side of mounting bracket 113 opposite to inner liner 112, and locking element 150 is rotatably mounted on the side of mounting bracket 113 opposite to main unit 110.

[0083] In the embodiments of this application, by mounting the fastener 140 and the locking member 150 on the side of the mounting bracket 113 away from the host 110, the space required to install the fastener 140 and the locking member 150 along the first axis direction is reduced to a certain extent, making the cooking appliance 100 compact in structure and small in size.

[0084] The outer cover 114 covers the inner liner 112, and at least a portion of the operating part 160 extends out from the outer cover 114.

[0085] The outer cover 114, which covers the inner pot 112, protects the inner pot 112. Additionally, the outer cover 114 acts as heat insulation, preventing direct contact between the heat of the inner pot 112 and the user, thus avoiding burns. By extending at least a portion of the operating part 160 from the outer cover 114, it facilitates user operation. When food is cooked and the door 120 needs to be opened to remove it, the door 120 is closed and the locking member 150 is in the first position. The user can operate the operating part 160 to rotate the locking member 150 towards the second position until it reaches the second position. At this point, the first lock of the cooking appliance 100 is released. Simultaneously, the user can grasp the door handle 121 and pull the door 120 outwards with minimal force. With the release of the second lock, the door 120 and the main unit 110 of the cooking appliance 100 are also unlocked.

[0086] Reference Figure 3 , Figure 5 as well as Figure 7 The first end of the locking member 150 is rotatably connected to the mounting bracket 113, and the second end of the locking member 150 is used to lock into the fastener 140.

[0087] Because the pivot position of the locking component 150 and the locking part of the locking component 150 are respectively located at both ends of the locking component 150, the locking effect is good, and the locking part structure is simple and easy to process.

[0088] Furthermore, referring to Figure 7 and Figure 8 The side of the fastener 140 is provided with a notch 141 to form an abutment surface 142 that extends radially along the pivot axis. In the first position, the second end of the locking member 150 can abut against the abutment surface 142.

[0089] In the above embodiment, the locking member 150 is in the first position, and the second end of the locking member 150 abuts against the abutment surface 142, thereby locking the fastener 140, resulting in a simple structure. Furthermore, the abutment surface 142 is formed by creating a notch 141 on the side of the fastener 140, with one side wall of the notch 141 forming the abutment surface 142. This ensures that the second end of the locking member 150 is positioned within the notch 141 when locked, reducing the arrangement space of the locking member 150 and the fastener 140 along the first axis to a certain extent, making the cooking utensil 100 compact and aesthetically pleasing.

[0090] It should be noted that, in other embodiments, the abutment surface 142 can also be formed by protruding an abutment platform on the locking member 150, with the abutment surface 142 formed on one side of the abutment platform.

[0091] Reference Figure 3 The locking component 150 includes a locking arm 151 and a locking shaft 152. The first end of the locking arm 151 is provided with a through hole 153. The second end of the locking arm 151 is locked in place with the fastener 140. The locking shaft 152 is anti-rotationally engaged with the through hole 153. One end of the locking shaft 152 extends out of the through hole 153 and is rotatably connected to the mounting bracket 113. The other end of the locking shaft 152 extends out of the through hole 153 and is connected to the operating part 160.

[0092] The locking arm 151 and the mounting bracket 113 are connected by a locking shaft 152, which has a simple structure and is easy to install. In addition, the locking shaft 152 and the through hole 153 are anti-rotationally engaged by providing an anti-rotation groove 154 on one of the locking shaft 152 and an anti-rotation protrusion 155 on the other. The anti-rotation groove 154 and the anti-rotation protrusion 155 cooperate to achieve the anti-rotational engagement between the locking shaft 152 and the through hole 153, so that the rotation of the locking shaft 152 will drive the locking arm 151 to rotate synchronously.

[0093] Reference Figure 3 as well as Figure 8 The outer periphery of the locking shaft 152 is provided with a first flange 156. The first flange 156 is located on the side of the through hole 153 away from the mounting bracket 113, and the end face of the first flange 156 is used to abut against the periphery of the through hole 153.

[0094] By setting a first flange 156, and having the end face of the first flange 156 abut against the periphery of the through hole 153, the locking shaft 152 is prevented from moving toward the mounting bracket 113, thus avoiding stress concentration and damage to the mounting bracket 113.

[0095] Reference Figure 1 and Figure 2The outer cover 114 is provided with a clearance opening. The locking shaft 152 extends out of the clearance opening and is connected to the operating part 160. The outer periphery of the locking shaft 152 is provided with a second flange 157. The second flange 157 is located inside the outer cover 114, and the end face of the second flange 157 is used to abut against the periphery of the clearance opening to limit the locking shaft 152 and prevent the locking shaft 152 from falling out of the clearance opening.

[0096] It should be noted that the principle by which the end face of the second flange 157 abuts against the periphery of the clearance opening is that the size of the second flange 157 is larger than the size of the clearance opening, so that the end face of the second flange 157 can abut against the periphery of the clearance opening.

[0097] Specifically, there are multiple ways to connect the locking shaft 152 to the operating part 160. In one embodiment, the locking shaft 152 and the operating part 160 can be engaged by a snap-fit ​​mechanism with a snap-fit ​​protrusion and a snap-fit ​​groove. In other embodiments, the operating part 160 can also be integrally formed with the locking shaft 152, or the locking shaft 152 and the operating part 160 can be welded and fixed or connected by glue or the like. Specifically, this application does not limit this.

[0098] Reference Figure 4 and Figure 6 The fastening element 140 has an upward-opening fork 144. The latching opening of the door hook 130 engages with the fork 144. Since the opening of the fork 144 of the fastening element 140 is upward, when it is necessary to disengage the latching opening of the door hook 130 from the fork 144, a downward force needs to be applied to the fork 144 to rotate the opening of the fork 144 downward. The door hook 130 is usually connected to the handle; therefore, a downward force needs to be applied to the handle when opening the door. This simple operation conforms to human force application habits and improves the user experience.

[0099] The fastening member 140 has a pivot portion 145, a fork portion 144, and a locking portion 147.

[0100] The pivoting part 145 is pivotally mounted to the main unit 110.

[0101] Specifically, the main unit 110 is provided with a pivot shaft 115, and a boss 116 is provided on the side wall of the pivot shaft 115. The pivot part 145 is provided with a mounting hole 148, and a guide groove 149 is provided in the inner wall surface of the mounting hole 148 along its axial direction. During installation, the guide groove 149 is aligned with the boss 116, the pivot part 145 is fitted onto the pivot shaft 115, and the pivot part 145 slides close to the main unit 110, so that the boss 116 protrudes from the guide groove 149. Rotating the pivot part 145 causes the end face of the boss 116 facing the main unit 110 to abut against the end face of the pivot part 145 away from the main unit 110. The boss 116 and the guide groove 149 are staggered along the rotation direction of the locking member 150, which restricts the movement of the pivot part 145 in the direction away from the main unit 110 and prevents the pivot part 145 from falling off the pivot part 145. In addition, the boss 116 provides a predetermined rotational friction force to the pivot 145, so that the pivot 145 can be rotated by a predetermined external force and can also maintain the current angular position (i.e., the current position) after the external force is removed.

[0102] Both the fork portion 146 and the locking portion 147 are connected to the pivot portion 145 and are spaced apart circumferentially along the pivot portion 145. The fork portion 146 engages with the door hook 130, thereby locking the door body 120 relative to the host 110, thus completing the second locking mechanism in the above embodiment. The locking portion 147 engages with the locking member 150, thereby locking the pivot portion 145, thus completing the first locking mechanism in the above embodiment.

[0103] In some embodiments, the pivot portion 145, the fork portion 146, and the locking portion 147 may be integrated into one unit.

[0104] Specifically, the locking part 147 is provided with a notch 141, and the locking member 150 is adapted to move into the notch 141 to lock and engage with the fastening member 140. The notch 141 not only serves as a locking mechanism, but also reduces the arrangement space of the locking member 150 and the fastening member 140 along the first axis to a certain extent, making the cooking utensil 100 small and aesthetically pleasing.

[0105] In some embodiments, such as Figures 4 to 7 As shown, the cooking appliance 100 may also include a first reset member 170.

[0106] The first reset member 170 can be elastically connected between the locking member 150 and the host 110. The first reset member 170 can be used to drive the locking member 150 to remain in the first position.

[0107] Reference Figure 6In the embodiments of this application, the first reset member 170 includes a first torsion spring. Both the host 110 and the locking member 150 are provided with a mounting hole 180. The two ends of the torsion spring are respectively mounted in the two mounting holes 180, thereby realizing the connection between the first reset member 170, the host 110 and the locking member 150, so that the locking member 150 can be held in the first position.

[0108] In actual operation, when the user rotates the operating part, the locking member 150 can rotate from the first position to the second position. During this process, the first reset member 170 located between the main unit 110 and the locking member 150 is continuously compressed, and the elastic force applied by the first reset member 170 to the locking member 150 continuously increases until the locking member 150 overcomes the elastic force and slides 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 120 down, thereby unlocking the second lock of the cooking appliance 100.

[0109] After the door is opened, the user can release the operating part 160. After the force applied to the locking part 150 to overcome the elasticity disappears, the locking part 150 can rotate from the second position to the first position, realizing the automatic reset of the locking part 150. The operation is simple.

[0110] The cooking appliance 100 provided in this application embodiment, through the setting of the first reset member 170, allows the locking member 150 to automatically return to the first position after the user releases the operating part 160. The setting of the snap-fit ​​hole 180 makes the first reset member 170 less likely to fall off and more durable. At the same time, the structure is simple, the assembly parts are simple, the requirements for processing precision are low, and it is easy to install.

[0111] In some embodiments, the cooking appliance 100 further includes a second reset member 190, which is elastically connected between the fastener 140 and the main unit 110. When the door is opened, the torques of the second reset member 190 and the door hook 130 on the fastener 140 are opposite.

[0112] By setting a second reset member 190 connected between the fastener 140 and the host 110, when the door is opened, the torques of the second reset member 190 and the door hook 130 on the fastener 140 are opposite. This allows the door 120 to automatically return to its initial position under the action of the second reset member 190 after the external force acting on the door body 120 is removed. The structure is simple and easy to operate.

[0113] Specifically, refer to Figure 3 and Figure 4 The second reset member 190 can be a torsion spring. Of course, in other embodiments, the second reset member 190 can be selected as needed, and this application does not limit it.
