[0055] 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.

[0056] Reference below Figures 1-8 A door of a cooking appliance according to an embodiment of the present application is described.

[0057] like Figure 1 、 Figure 2 as well as Figure 4 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;

[0058] The main unit 110 has a cooking cavity 111 .

[0059] 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 receiving container and cooperate with the door 120 to provide a closed environment for food.

[0060] 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.

[0061] The door hook 130 can be installed on the door body 120 and can extend from the back plate of the door body 120.

[0062] 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.

[0063] The fastening member 140 is pivotally mounted on the host 110 about a first axis and can be used to fasten with the door hook 130 .

[0064] 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.

[0065] The locking member 150 is slidably installed on the main unit 110 between a first position and a second position along a first direction. The first direction is perpendicular to the first axis. The locking member 150 is suitable for locking with the fastening member 140 when in the first position. The locking member 150 is suitable for unlocking with the fastening member 140 when in the second position. When the fastening member 140 is unlocked and the door body 120 rotates in the direction of opening the door, the door hook 130 is used to drive the fastening member 140 to rotate in the direction of disengaging from the door hook 130.

[0066] 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.

[0067] 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).

[0068] The operating portion 160 is slidably mounted on the host 110 along a first direction and can be connected to the locking member 150 . The operating portion 160 is at least used to drive the locking member 150 to slide from the first position to the second position.

[0069] Specifically, the operating part 160 extends outward from the door body 120 to facilitate manual operation. The operating part 160 is manually controlled to drive the locking member 150 to slide from the first position to the second position, thereby realizing the first unlocking of the cooking appliance 100. 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 so that the door body 120 will be separated from the main body of the cooking appliance 100 and opened.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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 an adhesive connection. For example, in some embodiments, the connection between the operating portion 160 and the locking member 150 is an interference fit. In other embodiments, the operating portion 160 and the locking member 150 may be fixed by screwing.

[0074] In actual implementation, refer to Figure 1 The operating portion 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 portion 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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 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.

[0080] 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.

[0081] 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.

[0082] Reference Figure 2 The main unit 110 includes an inner shell 112 , a mounting frame 113 and an outer cover 114 .

[0083] Specifically, the inner pot 112 has a cooking cavity 111, which can serve as a receiving container and cooperate with the door body 120 to provide a closed environment for food.

[0084] 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 .

[0085] 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.

[0086] 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 .

[0087] 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.

[0088] Reference Figure 2 、 Figure 4 as well as Figure 8 The locking member 150 includes a connecting arm 151 and a locking arm 152 .

[0089] The connecting arm 151 is slidably mounted on the mounting bracket 113 , and a side of the connecting arm 151 facing away from the mounting bracket 113 is connected to the operating portion 160 .

[0090] When an external force is applied to the operating portion 160 , since the side of the connecting arm 151 facing away from the mounting bracket 113 is connected to the operating portion 160 , the connecting arm 151 can move synchronously with the operating portion 160 , resulting in a simple structure.

[0091] The locking arm 152 is protruded from the first side wall of the connecting arm 151 , and is adapted to be locked with the fastening member 140 .

[0092] The locking arm 152 and the connecting arm 151 are connected as a whole, and the locking arm 152 moves synchronously with the connecting arm 151. During the movement of the locking arm 152, the locking arm 152 and the buckle 140 are locked or unlocked, and the structure is simple.

[0093] It should be noted that in the embodiment of the present application, the locking arm 152 and the connecting arm 151 are integrally formed. Of course, in other embodiments, the locking arm 152 and the connecting arm 151 can also be detachably connected, for example, by a snap-fit ​​structure, or by a threaded connection through a threaded structure, etc. This application does not limit this.

[0094] Reference Figure 3 The mounting frame 113 has a guide groove 115 , and the connecting arm 151 is slidably mounted in the guide groove 115 .

[0095] The guide groove 115 not only facilitates the installation of the locking member 150 but also serves as a guide. Furthermore, to reduce friction between the locking member 150 and the guide groove 115, the inner wall of the guide groove 115 and / or the outer surface of the locking member 150 are smooth. This reduces friction, prevents wear of the guide groove 115 and the locking member 150 over extended use, and thus increases their service life.

[0096] Furthermore, a limiting structure is provided between the inner wall surface of the guide groove 115 and the locking member 150. By providing the limiting structure to limit the movement of the locking member 150 along the first axis direction, the locking member 150 is prevented from falling out of the guide groove 115, and installation is convenient.

[0097] Specifically, refer to Figure 3 as well as Figure 8 The limiting structure includes a limiting boss 171 extending along the first direction and a limiting groove 172 adapted to the limiting boss 171. One of the limiting boss 171 and the limiting groove 172 is provided in the guide groove 115, and the other is provided in the locking member 150. The limiting boss 171 and the limiting groove 172 cooperate to limit the locking member 150. The structure is simple and easy to process. At the same time, it has high positioning accuracy, is easy to move, and has little wear, which has a positive effect on extending the service life of components.

[0098] It should be noted that, in other embodiments, the operating portion 160 may 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.

[0099] Reference Figure 5 、 Figure 7 as well as Figure 8 A support plate 153 is provided on the two second side walls of the connecting arm 151 that are opposite and spaced apart. The two support plates 153 are respectively located on both sides of the first side wall, and each support plate 153 abuts against the periphery of the notch of the guide groove 115.

[0100] Taking into account the risk of shaking of the connection part during actual operation, the two support plates 153 are abutted against the periphery of the notch of the guide groove 115 to support the connection arm 151, thereby improving the sliding stability of the connection arm 151 and achieving good results.

[0101] The outer peripheral wall of the operating portion 160 is provided with an outwardly protruding flange, and the outer cover 114 is provided with an escape opening 116. The operating portion 160 extends from the escape opening 116, facilitating operation by an operator to apply external force to the operating portion 160. The flange is located on the inner side of the outer cover 114 and is larger than the escape opening 116. This allows the end surface of the flange to abut against the perimeter of the escape opening 116, thereby limiting the position of the operating portion 160 and preventing it from falling out of the escape opening 116.

[0102] Reference Figure 1 The fastening member 140 has a shift fork 141 with an opening that opens upward. The fastening opening of the door hook 130 is engaged with the shift fork 141. Since the opening of the shift fork 141 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 141, it is necessary to apply a downward force to the shift fork so that the opening of the shift fork is rotated downward. Usually, the door hook 130 is connected to the door handle 121. Therefore, when opening the door, it is necessary to apply a downward force 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.

[0103] Reference Figure 4 as well as Figure 6 The fastening member 140 has a pivot portion 142 , a fork portion 143 and a locking portion 144 .

[0104] The pivoting portion 142 is pivotally mounted on the host 110 .

[0105] Specifically, a pivot shaft 145 is provided on the host 110, and a boss 146 is protruded from the side wall of the pivot shaft 145. A mounting hole 147 is provided on the pivot portion 142, and a guide groove 148 is penetrated along the inner wall surface of the mounting hole 147 along its axial direction. During installation, the guide groove 148 is aligned with the boss 146, and the pivot portion 142 is fitted on the pivot shaft 145, and the pivot portion 142 is slid close to the host 110 so that the boss 146 protrudes from the guide groove 148. The pivot portion 142 is rotated so that the end face of the boss 146 facing the host 110 abuts against the end face of the pivot portion 142 away from the host 110, and the boss 146 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 142 in the direction away from the host 110, thereby preventing the pivot portion 142 from falling off the pivot portion 142. In addition, the boss 146 provides a predetermined rotational friction force to the pivoting portion 142, so that the pivoting portion 142 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.

[0106] The fork portion 143 and the locking portion 144 are both connected to the pivot portion 142 and spaced apart along the circumference of the pivot portion 142. The fork portion 143 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 144 engages with the locking member 150 to lock the pivot portion 142, thus completing the first locking step of the above-described embodiment.

[0107] In some embodiments, the pivot portion 142 , the fork portion 143 , and the locking portion 144 may be integrated.

[0108] Specifically, the locking portion 144 is provided with a locking hole 149, and the locking member 150 is suitable for extending into the locking hole 149 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 push the operating portion 160 in the first direction, and the operating portion 160 can drive the locking member 150 to slide in the first direction until the locking member 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 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 145. 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.

[0109] It should be noted that the principle by which the locking member 150 and the locking hole 149 lock the snapping member 140 is that the locking hole 149 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 149 is formed. Of course, in other embodiments, the locking portion 144 can also be a locking arm 152 extending radially along the pivot axis 145, and the locking arm 152 is formed with a locking surface, 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.

[0110] In some embodiments, as Figure 2 、 Figure 6 and Figure 8 As shown, the cooking appliance 100 may further include a first restoring member 180 .

[0111] 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.

[0112] To prevent the first restoring member 180 from being misaligned and affecting the restoring effect, the host 110 is provided with a first connecting post 117. One end of the first restoring member 180 can be connected to the first connecting post 117, and the other end of the first restoring member 180 can be connected to the locking member 150. Specifically, in an embodiment of the present application, the locking member 150 is provided with a second connecting post, which is connected to the other end of the first restoring member 180 via the second connecting post. The first restoring member 180 can be in a compressed state, and the elastic force of the first restoring member 180 can drive the locking member 150 to slide toward the first position. Of course, in other embodiments, the first restoring member 180 can be in a stretched state, and the elastic restoring force of the first restoring member 180 can drive the locking member 150 to slide toward the first position.

[0113] Specifically, the first restoring member 180 may be a spring or an elastic rubber sleeve, which is not limited here.

[0114] In actual implementation, when the user pushes the operating part 160 to slide along the first direction, 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 first connecting column 117 and the second connecting column 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.

[0115] 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 first connecting column 117 and the locking member 150 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.

[0116] 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 groove 115, allows the locking member 150 to automatically return to the first position after the user releases the operating part 160. The first connecting column 117 and the second connecting column are connected to the first return spring, 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 accuracy requirements are low, and it is easy to install.

[0117] 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 a pushing force is applied to the operating portion 160, the first return element 180 is a compression spring. The operating portion 160 is pushed 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 a pulling force is applied to the operating portion 160, the first return element 180 is an extension spring. The operating portion 160 is pulled 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.

[0118] 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 setting the above-mentioned guide groove 115 in conjunction with the design of the first reset member 180. The guide groove 115, the first reset member 180, the first connecting column 117 and the second connecting column 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.

[0119] In some embodiments, the cooking appliance 100 further includes a second restoring member 190 , which is elastically connected between the fastening member 140 and the host 110 . When the door is opened, the second restoring member 190 and the door hook 130 exert opposite torques on the fastening member 140 .

[0120] 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.

[0121] 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.
