[0057] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0058] Reference below Figures 1-9 A door of a cooking appliance according to an embodiment of the present application is described.

[0059] like Figures 1 to 3 As shown, the cooking appliance 100 includes a main unit 110, a door body 120, a door hook 130, a fastener 140, a lock 150 and an operating portion 160;

[0060] The main unit 110 has a cooking cavity 111 .

[0061] The main unit 110 can be used to cook food through temperature control and time control, and the cooking cavity 111 can serve as a container and cooperate with the door 120 to provide a closed environment for food.

[0062] The door body 120 is pivotally mounted to the main unit 110 so that the door body 120 can be rotated to a certain angle to open the cooking cavity 111, making it easier for the operator to place the food to be heated into the cooking cavity 111. Once the food to be heated is placed, the door body 120 can be rotated to close the cooking cavity 111, thereby providing heat preservation and insulation. At the same time, it prevents the operator from being scalded during the heating process, thereby improving safety. In addition, a door handle 121 can be provided on the outer panel 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, the door body 120 can also be provided with a perspective window to facilitate observing the status of the food in the main unit 110; in other examples, the door body 120 can also be provided with a control panel for controlling the operation of the electrical appliances in the main unit 110.

[0063] The door hook 130 can be installed on the door body 120 and can extend from the back plate of the door body 120.

[0064] During daily use, the door hook 130 extends from the back panel of the door body 120, preventing impurities and dirt from entering the door body 120, thus facilitating cleaning of the cooking appliance 100. The portion of the door hook 130 extending from the back panel engages with the fastener 140, locking the door body 120 relative to the main unit 110. The fastener 150 extending from the back panel of the door body 120 enhances the aesthetics of the door body 120. Furthermore, when the door body 120 is opened, there are no protruding portions on the side of the door body 120, preventing the fastener 150 from accidentally striking a person.

[0065] The fastening member 140 is pivotally mounted on the host 110 around the first axis and can be used to fasten with the door hook 130. The fastening member 140 is provided with a locking hole 141 and a strip hole 142 connected to the locking hole 141 along the direction of the first axis. The strip hole 142 is extended circumferentially along the pivot axis of the fastening member 140.

[0066] During the actual cooking process, the cooking cavity 111 needs to be closed, and the door body 120 and the main unit 110 are locked by engaging the fastener 140 with the door hook 130, which is safe and reliable.

[0067] The locking member 150 is slidably mounted on the host 110 between a first position and a second position along the first axis direction. The locking member 150 includes a connecting arm 151 and a locking flange 152 protruding from the connecting arm 151 (see FIG. Figure 9 ), when the locking member 150 is in the first position, the locking flange 152 is clamped in the locking hole 141 to limit the rotation of the fastening member 140. When the locking member 150 is in the second position, the locking flange 152 extends out of the locking hole 141, so that the connecting arm 151 can slide from the locking hole 141 to the bar hole 142 to release the restriction on the rotation of the fastening member 140. When the fastening member 140 releases the rotation restriction and the door body 120 rotates in the door opening direction, the door hook 130 is used to drive the fastening member 140 to rotate in the direction of disengagement from the door hook 130.

[0068] By making the locking member 150 lock the fastening member 140 in the first position, driving the locking member 150 to slide from the first position to the second position, the first unlocking of the cooking appliance 100 is achieved, and the door body 120 is manipulated again to release the fastening member 140 from the door hook 130, and the door body 120 is pulled, and the door body 120 will be separated from the main unit 110 of the cooking appliance 100 and opened. A two-step unlocking operation is required to open the door body 120, thereby improving safety.

[0069] The locking component 150 can be made of metal or plastic. For example, in some embodiments, the locking component 150 is made of plastic, wherein the plastic material may include but is not limited to PP (Polypropylene), POM (Polyformaldehyde), and PC (Polycarbonate).

[0070] The operating portion 160 may be connected to the locking member 150 and at least used to drive the locking member 150 to slide from the first position to the second position.

[0071] Specifically, refer to Figure 1 and Figure 2 The operating portion 160 extends outward from the door body 120 for manual operation. The operating portion 160 is manually controlled to drive the locking member 150 to slide from the first position to the second position. In the first position, the locking flange 152 is clamped in the locking hole 141, thereby limiting the rotation of the fastening member 140. By applying external force to the operating portion 160, the locking flange 152 extends out of the locking hole 141, so that the connecting arm 151 can slide from the locking hole 141 to the bar hole 1 42, in order to release the restriction on the rotation of the fastener 140. Since the strip hole 142 is circumferentially extended along the pivot axis of the fastener 140, the strip hole 142 provides avoidance for the rotation of the fastener 140, thereby realizing the first unlocking of the cooking utensil 100, and manipulating the door body 120 again to rotate the fastener 140. During the rotation process, the fastener 140 can be released from the door buckle, and the door body 120 can be pulled, and the door body 120 will be separated from the main body of the cooking utensil 100 and opened.

[0072] In actual implementation, the user can put the food to be cooked into the cooking cavity 111. After the food is cooked, the user can apply force to the operating part 160. The applied force can be pressure or tension, so that the locking member 150 starts to slide from the first position until the locking member 150 slides 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 body 120 outward with a small force, so that the fastener 140 and the door hook 130 are unfastened. At this time, the door body 120 and the main unit 110 of the cooking appliance 100 can also be unlocked accordingly. After the user opens the door body 120, he takes out the cooked food. After closing the door body 120, the fastener 140 and the door hook 130 are fastened, so that the door body 120 and the main unit 110 of the cooking appliance 100 are locked again.

[0073] The cooking appliance 100 provided in the embodiment of the present application utilizes a double-lock design, requiring the user to complete a two-step unlocking process before the door can be opened, thereby reducing the risk of children being scalded by opening and touching heated food and drinks. At the same time, the overall structure of the child lock is simple, the operation is convenient and quick, and the cost is low, which greatly improves the practicality and economy of the device.

[0074] It should be noted that the cooking appliance 100 may include but is not limited to a microwave oven, an oven or a steam-bake combination machine, for example, in some embodiments, Figure 1 and Figure 2 As shown, the cooking appliance 100 is a microwave oven.

[0075] In addition, the connection between the operating portion 160 and the locking member 150 may include, but is not limited to, an interference fit, a pin connection, or bonding. For example, in some embodiments, the connection between the operating portion 160 and the locking member 150 is an interference fit. In some embodiments, the operating portion 160 may also be threadedly connected to the locking member 150. Specifically, in the embodiment of the present application, the operating portion 160 and the locking member 150 are integrally formed, which facilitates processing.

[0076] In actual implementation, the operating part 160 can be at least partially exposed to the outside to facilitate user operation. When the food is cooked and the door body 120 needs to be opened to take out the food, the door body 120 is in a closed state and the locking member 150 is in the first position. The user can operate the operating part 160 to make the locking member 150 slide 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 body 120 outward with a small force. As the second lock is released, the door body 120 and the main unit 110 of the cooking appliance 100 can also be unlocked accordingly.

[0077] In the related art, in order to prevent children from accidentally opening the door, some cooking appliances are also provided 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 arranged under the front panel of the door.

[0078] However, in actual use, the above solution has many disadvantages: since the above-mentioned child lock structure is located on the side panel of the door body, the side panel of the door body needs to be grooved for the child lock structure to extend out, making it very easy for impurities and dirt to enter the door body, increasing the difficulty of cleaning the cooking utensils; secondly, the above-mentioned operating part is located on the front panel facing the user, and the height of the operating part is relatively low, so that children can easily touch the operating part, thereby slightly weakening the protective effect of the child lock.

[0079] The cooking utensil 100 provided in the embodiment of the present application, through the arrangement of the above-mentioned locking member 150 and the operating portion 160, adds a mechanical child lock structure on the basis of the original door opening system to ensure that before completing the door pulling action, the child lock must first be released to complete the entire door opening action, thereby preventing children from touching the heated food and getting burned after pulling open the door body 120, thereby helping to improve the safety and reliability of the entire cooking utensil 100.

[0080] Reference Figure 1 and Figure 2 The pivot axis of the door body 120 is located below the main unit 110, allowing the door body 120 to be configured as a bottom-opening door. The fastener 140 is mounted on the upper side of the main unit 110, and the lock 150 is correspondingly located on the upper side of the main unit 110. Accordingly, the operating unit 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.

[0081] In actual implementation, based on the pivot axis of the door body 120 being located at the lower part of the main unit 110, and taking into account the user's door opening force, the door handle 121 can be installed at a position of the door body 120 close to the upper part of the main unit 110, and the corresponding buckle 140 can be installed on the upper side of the main unit 110. When the food is cooked and the door body 120 needs to be opened to take out the food, the user can slide the operating part 160, and the operating part 160 can drive the locking part 150 to slide along the first axis direction until the locking part 150 slides from the first position to the second position. At this time, the first lock of the cooking appliance 100 is released, and the user can hold the door handle 121 and pull the door body 120 with a small force. The upper end of the door body 120 can be separated from the main unit 110 of the cooking appliance 100 and can be rotated downward around the pivot axis. As the second lock is released, the door body 120 and the main unit 110 of the cooking appliance 100 can also be unlocked accordingly.

[0082] Secondly, since the operating part 160 needs to drive the locking part 150, and the locking part 150 can be suitable for unlocking or locking the fastening part 140, the operating part 160 needs to be arranged adjacent to the fastening part 140. In the above embodiment, the fastening part 140 can be installed on the upper side of the host 110. Therefore, the operating part 160 does not directly face the user, and the height of the operating part 160 is relatively high, and it is difficult for children to easily touch the operating part 160, so that the safety of the child lock structure is guaranteed.

[0083] The cooking appliance 100 provided in this embodiment of the present application utilizes the aforementioned unlocking mechanism for the downward-opening door, which conforms to the human body's habit of exerting external force. This reduces the space occupied by the entire cooking appliance 100, improves volume utilization, and facilitates overall layout. Furthermore, the downward-opening door 120 can be used to transfer hot food from the cooking vessel, making it easier for users to remove and place food, thereby optimizing the overall user experience.

[0084] Reference Figure 2 The main unit 110 includes an inner shell 112 , a mounting frame 113 and an outer cover 114 .

[0085] Specifically, the inner pot 112 has a cooking cavity 111, which can serve as a container and cooperate with the door body 120 to provide a closed environment for food.

[0086] The mounting frame 113 is mounted on the inner container 112 . The buckle 140 is pivotally mounted on a side of the mounting frame 113 away from the inner container 112 . The locking member 150 is slidably mounted on a side of the mounting frame 113 away from the main unit 110 .

[0087] In the embodiment of the present application, by making the fastening member 140 and the locking member 150 both installed on the side of the mounting frame 113 facing away from the main unit 110, the space required for installing the fastening member 140 and the locking member 150 along the extension direction of the pivot axis of the fastening member 140 is reduced to a certain extent, so that the cooking utensil 100 has a compact structure and a small size.

[0088] The outer cover 114 is disposed outside the inner container 112 , and at least a portion of the operating portion 160 extends from the outer cover 114 .

[0089] The outer cover 114, which covers the inner pot 112, protects the inner pot 112. Furthermore, the outer cover 114 acts as a heat insulator, preventing the heat from the inner pot 112 from directly contacting the user and potentially scalding the user. By having at least a portion of the operating portion 160 extend from the outer cover 114, user operation is facilitated. When food is cooked and the door 120 needs to be opened to remove the food, the door 120 is closed and the lock 150 is in the first position. The user can operate the operating portion 160 to slide the lock 150 toward the second position until it reaches the second position. At this point, the first lock of the cooking appliance 100 is released. The user can then grasp the door handle 121 and pull the door 120 outward with minimal force. As the second lock is released, the door 120 and the main unit 110 of the cooking appliance 100 are unlocked.

[0090] Refer to,4. Figure 5 as well as Figure 7 The host 110 further includes a guide portion 170 , which is mounted on the inner wall of the outer cover 114 . A guide channel 171 extending along the first axis is formed inside the guide portion 170 .

[0091] Reference Figure 2The outer cover 114 is provided with an escape opening 116, which allows the guide portion 170 to at least partially extend outward from the outer sidewall surface, facilitating user operation. Furthermore, there are various ways to attach the guide portion 170 to the sidewall of the outer cover 114. For example, in one embodiment, it can be secured with double-sided tape or glue. In other embodiments, it can be secured with a snap-fit ​​structure. Specifically, in the embodiment of the present application, the guide portion 170 is secured to the inner wall surface of the outer cover 114 with screws, ensuring a secure connection and preventing shaking.

[0092] Reference Figures 5 to 7 The locking member 150 further includes a guide body 153, which is connected to the end of the connecting arm 151 away from the locking flange 152. The guide body 153 is mounted within the guide channel 171 and slidably abuts against the inner wall of the guide channel 171, thereby both securing the guide body 153 and guiding it during movement. The locking flange 152 can extend from one end of the guide channel 171 and engage with the locking hole 141. The operating portion 160 can extend from the other end of the guide channel 171 and connect to the side of the guide body 153 facing away from the connecting arm 151.

[0093] Since the operating portion 160 is connected to the side of the guide body portion 153 facing away from the connecting arm 151, when an external force is applied to the operating portion 160, when the operating portion 160 moves, the operating portion 160 will drive the guide body portion 153 to move, so that the locking flange 152 can move to be locked in the locking hole 141 to limit the rotation of the locking member 150, or the locking flange 152 can extend out of the locking hole 141, so that the connecting arm 151 can slide from the locking hole 141 to the strip hole 142 to release the rotation restriction of the fastening member 140. The structure is simple, which greatly improves the sliding stability of the locking member 150; at the same time, the positioning accuracy is high, the movement is light, and the wear is small, which has a positive effect on extending the service life of the components.

[0094] It should be noted that the operating portion 160 may also be integrally formed with the locking member 150 , or the locking member 150 and the operating portion 160 may be threadedly connected, etc. Specifically, this application does not limit this.

[0095] Reference Figure 7 The end of the guide channel 171 away from the mounting frame 113 is stepped to form a first abutting surface 172 set toward the mounting frame 113. The first abutting surface 172 is used to abut against the end surface of the guide main body 153 away from the mounting frame 113, thereby limiting the movement of the guide main body 153 and preventing the guide main body 153 from moving too far and detaching from the guide channel 171. The structure is simple and safe and reliable.

[0096] The operating portion 160 is connected to the guide body portion 153 through the first abutment surface 172. The operating portion 160 can move synchronously with the guide body portion 153. When an external force is applied, the operating portion 160 moves under the action of the external force, which will drive the guide body portion 153 to move. The structure is simple.

[0097] It should be noted that the operating portion 160 and the guide body portion 153 can be integrally formed, which simplifies the processing steps and improves production efficiency. Of course, in other embodiments, the operating portion 160 and the guide body portion 153 can also be bonded by glue or threadedly connected by a threaded structure. Specifically, this application does not limit this.

[0098] Reference Figure 7 as well as Figure 8 The guide portion 170 includes a housing 173 and a cover 174 arranged in sequence along the first direction. The housing 173 and the cover 174 are detachably connected. Thus, when the locking member 150 needs to be installed, the housing 173 and the cover 174 are disassembled and separated, making it easy to install the locking member 150 in the guide channel 171. The housing 173 and the cover 174 are then connected, making the operation simple. In addition, the locking member 150 can be easily replaced after long-term use, which causes wear and tear of the locking member 150.

[0099] The guide channel 171 is provided through the housing 173 and the cover 174 , so that the locking member 150 can be easily installed, with a simple structure and easy operation.

[0100] At least two latching grooves 175 are formed through the side wall of the guide channel 171 . The at least two latching grooves 175 are spaced apart along the circumference of the guide channel 171 .

[0101] In the embodiment of the present application, two slots 175 are provided, and the two slots 175 are provided on the side walls of the guide channel 171 and are spaced apart. This simplifies the structure. Of course, in other embodiments, three, four, or five slots 175 can also be provided. Specifically, there is no limitation on the number of slots 175.

[0102] The cover 174 extends toward the housing 173 and is provided with at least two clamping arms 176 . The at least two clamping arms 176 correspond one-to-one to the at least two clamping slots 175 . The at least two clamping arms 176 can extend into the guide channel 171 and be clamped with the corresponding clamping slots 175 .

[0103] By making at least two clamping arms 176 engage with at least two clamping slots 175 in a locking and rotational manner, a detachable connection between the cover 174 and the shell 173 is achieved, which has a simple structure and is easy to operate.

[0104] During actual operation, since the card slot 175 is set through the side wall, when it is necessary to separate the shell 173 and the cover body 174, an external force is applied to the card arm 176 located in the card slot 175, so that the card arm 176 is detached from the card slot 175, and the cover body 174 can be separated. The operation is simple and does not require screws or the like to fix it, thereby improving the aesthetics.

[0105] It should be noted that, in other embodiments, the shell 173 and the cover 174 can also be fixed by glue or fixed by screws. Specifically, this application does not limit this.

[0106] Reference Figure 1 The fastening member 140 has a shift fork 143 with an opening that opens upward. The fastening opening of the door hook 130 is engaged with the shift fork 143. Since the opening of the shift fork 143 of the fastening member 140 is set upward, when it is necessary to release the fastening opening of the door hook 130 from the shift fork 143, a downward force needs to be applied to the shift fork 143 to rotate the opening of the shift fork 143 downward. Usually, the door hook is connected to the door handle 121. Therefore, when opening the door, a downward force needs to be applied to the door handle 121, which is simple to operate. This conforms to the human body's force application habits and improves the user experience.

[0107] The buckle 140 has a pivot portion 144 , a fork portion 145 , and a locking portion 146 .

[0108] The pivoting portion 144 is pivotally mounted on the host 110 .

[0109] Specifically, refer to Figures 5 to 7 , a pivot shaft 115 is provided on the host 110, and a boss 117 is protruded from the side wall of the pivot shaft 115, and a mounting hole 147 is provided on the pivot portion 144. The inner wall surface of the mounting hole 147 is penetrated by a guide groove 148 along its axial direction. During installation, the guide groove 148 is aligned with the boss 117, and the pivot portion 144 is fitted on the pivot shaft 115, and the pivot portion 144 is slid close to the host 110 so that the boss 117 protrudes from the guide groove 148. The pivot portion 144 is rotated so that the end face of the boss 117 facing the host 110 abuts against the end face of the pivot portion 144 away from the host 110, and the boss 117 and the guide groove 148 are staggered along the rotation direction of the locking member 150, which limits the movable stroke of the pivot portion 144 in the direction away from the host 110, thereby preventing the pivot portion 144 from falling off the pivot portion 144. In addition, the boss 117 provides a predetermined rotational friction force to the pivot portion 144, so that the pivot portion 144 can be rotated by a predetermined external force and can also maintain the current angular position (ie, the current position) after the external force is removed.

[0110] The fork portion 145 and the locking portion 146 are both connected to the pivot portion 144 and spaced apart along the circumference of the pivot portion 144. The fork portion 145 engages with the door hook 130 to lock the door body 120 relative to the main unit 110, thus completing the second locking step of the above-described embodiment. The locking portion 146 engages with the locking member 150 to lock the pivot portion 144, thus completing the first locking step of the above-described embodiment.

[0111] In some embodiments, the pivot portion 144 , the fork portion 145 , and the locking portion 146 may be integrally provided.

[0112] Specifically, the locking hole 141 and the bar hole 142 are both provided in the locking portion, and the locking member 150 is adapted to extend into the locking hole 141 to lock with the buckle 140, so that when the food is cooked and the door body 120 needs to be opened to take out the food, the user can press the operating portion 160 in the first direction, and the operating portion 160 can drive the locking member 150 to slide along the second axis direction until the locking member 150 slides from the first position to the second position, and the locking flange 152 extends out of the locking hole 141, so that the door body 120 is locked. The connecting arm 151 can slide from the locking hole 141 to the strip hole 142 to release the restriction on the rotation of the fastener 150. 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 body 120 with a small force. The upper end of the door body 120 can be separated from the main unit 110 of the cooking appliance 100 and can be rotated downward around the pivot axis 115. As the second lock is released, the door body 120 and the main unit 110 of the cooking appliance 100 can also be unlocked accordingly.

[0113] It should be noted that the principle by which the locking member 150 and the locking hole 141 lock the snapping member 140 is that the locking hole 141 is formed with a locking surface, and the locking member 150 has a locking mating end surface. By making the locking surface cooperate with the locking mating end surface, the snapping member 140 can be locked. Specifically, there are various ways to form the locking end surface. In the above embodiment, the locking hole 141 is formed. Of course, in other embodiments, the locking portion 146 can also be a locking arm extending radially along the pivot shaft 115, and the locking surface is formed on the locking arm, so that the locking mating end surface of the locking member 150 cooperates with the locking surface, thereby locking the snapping member 140. In addition, there are various ways to form the locking surface, which are not limited in this application.

[0114] In some embodiments, as Figure 7 and Figure 8 As shown, the cooking appliance 100 may further include a first restoring member 180 .

[0115] The first restoring member 180 may be elastically connected between the locking member 150 and the host 110 , and the first restoring member 180 may be used to drive the locking member 150 to remain in the first position.

[0116] Reference Figure 7 The end of the guide channel 171 facing the mounting frame 113 is stepped to form a second abutment surface 177 set away from the mounting frame 113. An installation space is formed between the second abutment surface 177 and the end surface of the guide body 153 facing the mounting frame 113. The first reset member 180 is elastically clamped in the installation space, and the locking member 150 is driven by the first reset member 180 to remain in the first position.

[0117] Specifically, the first restoring member 180 may be a spring or an elastic rubber sleeve, which is not limited here.

[0118] In actual implementation, when the user presses the operating part 160, the locking member 150 can slide from the first position to the second position. During this process, the first reset member 180 located between the second abutting surface 177 and the guide main body 153 is continuously compressed, and the elastic force applied by the first reset member 180 to the locking member 150 continues to increase 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 body 120 downward, thereby unlocking the second lock of the cooking appliance 100.

[0119] After opening the door, the user can release the operating part 160. After the manpower applied to the locking member 150 to overcome the elastic force disappears, the locking member 150 can slide from the second position to the first position. During this process, the first reset member 180 located between the second abutting surface 177 and the guide main body 153 continues to extend, and the elastic force applied by the first reset member 180 to the locking member 150 continues to decrease until the locking member 150 returns to the first position, thereby realizing automatic reset of the locking member 150 and simple operation.

[0120] The cooking utensil 100 provided in the embodiment of the present application, through the provision of the above-mentioned first return member 180 and the guiding function of the guide channel 171, allows the locking member 150 to automatically return to the first position after the user releases the operating portion 160. The second abutment surface 177 and the guide body portion 153 clamp the first return member 180, making the first return member 180 not easy to fall off and durable. At the same time, the structure is simple, the assembly parts are single, the processing precision requirements are low, and it is easy to install.

[0121] Specifically, the type of the first return element 180 can be selected based on the external force applied to the operating portion 160. For example, in an embodiment of the present application, when pressure is applied to the operating portion 160, the first return element 180 is a compression spring. The operating portion 160 is subjected to pressure and moves from the first position to the second position. During this process, the first return element 180 is compressed. When the external force applied to the operating portion 160 is removed, the operating portion 160 returns to the first position under the elastic force of the first return element 180. In other embodiments, when tension is applied to the operating portion 160, the first return element 180 is an extension spring. The operating portion 160 is subjected to tension and moves from the first position to the second position. During this process, the first return element 180 is stretched. When the external force applied to the operating portion 160 is removed, the operating portion 160 returns to the first position under the elastic force of the first return element 180.

[0122] The cooking utensil 100 provided in the embodiment of the present application realizes the sliding unlocking and elastic reset of the locking member 150 by means of the setting of the guide channel 171 and the design of the first reset member 180. The guide channel 171, the first reset member 180 and the second abutment surface 177 cooperate with each other so that the mechanical performance of the locking member 150 will not be significantly affected during the reciprocating motion, thereby increasing the reliability of the entire child lock structure.

[0123] In some embodiments, reference Figure 6 The cooking appliance 100 further includes a second reset member 190 , which is elastically connected between the fastening member 140 and the host 110 . When the door is opened, the second reset member 190 and the door hook 130 exert opposite torques on the fastening member 140 .

[0124] By setting a second reset member 190 connected between the fastening member 140 and the main unit 110, the second reset member 190 and the door hook 130 exert opposite torques on the fastening member 140 when the door is opened, so that when the external force acting on the door body 120 is removed, the door body 120 can automatically return to its initial position under the action of the second reset member 190. The structure is simple and easy to operate.

[0125] Specifically, the second restoring member 190 may be a torsion spring. Of course, in other embodiments, the second restoring member 190 may be selected as needed, and this application does not limit this.
