[0051] 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.
[0052] The following is for reference. Figures 1-8 Describes a door assembly of a cooking appliance according to an embodiment of this application.
[0053] 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 hook 150, and an operating part 160;
[0054] The main unit 110 has a cooking cavity 111.
[0055] The main unit 110 can be used to cook food through temperature control and time control, and the cooking cavity 111 can be used as a container to cooperate with the door to provide a closed environment for the food.
[0056] 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.
[0057] Door hook 130 can be installed on door body 120 and can extend from the back panel of door body 120.
[0058] In daily use, when the door hook 130 extends from the back panel of the door 120, impurities and dirt are less likely to enter the door 120, facilitating the cleaning of the cooking utensils 100. The portion of the door hook 130 extending from the back panel is used to engage with the fastener 140, enabling the door 120 to be locked relative to the main unit 110. By setting the locking hook 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 locking hook 150 from accidentally injuring a person.
[0059] The fastener 140 is pivotally mounted to the main unit 110 and can be used to engage with the door hook 130.
[0060] 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.
[0061] Reference Figure 3 , Figure 4 , Figure 6 as well as Figure 7The locking hook 150 is slidably mounted on the main unit 110 between a first position and a second position. In the first position, the locking hook 150 is adapted to lock with the fastener 140, and in the second position, the locking hook 150 is adapted to unlock with the fastener 140. When the fastener 140 is unlocked and the door 120 rotates in the opening direction, the fastener 140 is driven by the door hook 130 to rotate in the direction of disengagement from the door hook 130. The structure is simple and easy to operate.
[0062] 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).
[0063] The operating unit 160 can be connected to the locking hook 150, and the operating unit 160 can drive the locking hook 150 to slide from the first position to the second position.
[0064] 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 hook 150 is driven to slide 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 fastener 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.
[0065] In actual operation, the user can place 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, causing the locking hook 150 to slide from the first position until the locking hook 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 can hold the door handle 121 and pull the door 120 outward with a small force, so that the fastener 140 and the door hook 130 are unfastened. 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, he takes out the cooked food. After closing the door 120, the fastener 140 and the door hook 130 are fastened, so that the door 120 and the main unit 110 of the cooking appliance 100 are locked again.
[0066] 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.
[0067] 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.
[0068] In addition, the connection between the operating part 160 and the locking hook 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 hook 150 is an interference fit.
[0069] 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 hook 150 is in the first position. The user can operate the operating part 160 to make the locking hook 150 slide 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 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.
[0070] 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.
[0071] 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.
[0072] Reference Figure 4The cooking appliance 100 provided in this application embodiment, through the setting of the aforementioned locking hook 150 and operating part 160, adds a mechanical child lock structure to the original door opening system, ensuring that the child lock must be released before the door opening action can be completed, preventing children from touching heated food and being burned after opening the door 120, thus helping to improve the safety and reliability of the entire cooking appliance 100.
[0073] Reference Figure 4 The sliding direction of the locking hook 150 is parallel to the pivot axis of the fastener 140.
[0074] To a certain extent, this avoids mutual interference between the locking hook 150 and the fastener 140 during rotation, and reduces the space required to arrange the locking hook 150 and the fastener 140 on the main unit 110, making the cooking appliance 100 small and beautiful.
[0075] Reference Figure 1 and 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 hook 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.
[0076] 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 slide the operating part 160. The operating part 160 can drive the locking hook 150 to slide in the left and right direction until the locking hook 150 slides 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.
[0077] Secondly, since the operating part 160 needs to drive the locking hook 150, and the locking hook 150 can be adapted to unlock or lock the fastener 140, the operating part 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 part 160 does not directly face the user, and the height of the operating part 160 is relatively high, making it difficult for children to easily reach the operating part 160, thus ensuring the safety of the child lock structure.
[0078] 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, making it easy to operate and improving the user experience. In addition, it can make the entire cooking appliance 100 occupy less space, improving volume utilization and facilitating 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 out and put away food, thereby optimizing the overall user experience.
[0079] Reference Figure 2 The main unit 110 includes an inner tube 112, a mounting bracket 113, and an outer cover 114.
[0080] Specifically, the inner liner 112 has a cooking cavity 111, which can serve as a container and cooperate with the door 120 to provide a closed environment for food.
[0081] Mounting bracket 113 is mounted on inner liner 112, fastener 140 is pivotally mounted on the side of mounting bracket 113 away from inner liner 112, and locking hook 150 is slidably mounted on the side of mounting bracket 113 away from main unit 110.
[0082] In the embodiments of this application, by mounting the fastener 140 and the hook 150 on the side of the mounting bracket 113 away from the main unit 110, the space required to install the fastener 140 and the hook 150 along the extension direction of the pivot axis of the fastener 140 is reduced to a certain extent, making the cooking appliance 100 compact in structure and small in size.
[0083] 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.
[0084] 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 latch 150 is in the first position. The user can operate the operating part 160 to slide the latch 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.
[0085] Reference Figure 3 The mounting bracket 113 has a guide post 115, and a locking hook 150 is sleeved on the guide post 115. The locking hook 150 slides with the guide post 115, thus guiding the sliding of the locking hook 150. In addition, the operating part 160 is connected to the locking hook 150, so that when the operating part 160 is subjected to force, the operating part 160 moves, which can drive the locking hook 150 to move. The structure is simple and easy to operate.
[0086] Reference Figure 3 and Figure 8 The operating part 160 has a sliding groove 161, through which it slides and engages with the guide post 115. This facilitates the installation of the operating part 160 and provides guidance for its movement. The end face of the operating part 160 abuts against the locking hook 150, which also guides the movement of the hook 150. This achieves directional sliding of the locking hook 150 with high sensitivity and low frictional resistance, significantly improving the smoothness of its movement. Simultaneously, it offers high positioning accuracy, easy movement, and minimal wear, thus positively impacting the lifespan of components.
[0087] It should be noted that in the above embodiments, the locking hook 150 is provided with a through hole 152, and the locking hook 150 is fitted to the guide post 115 through the through hole 152. In other embodiments, the operating part 160 may also be integrally formed with the locking hook 150, or the locking hook 150 and the operating part 160 may be threadedly connected, etc. Specifically, this application does not limit this.
[0088] The outer peripheral wall of the operating part 160 is provided with an outwardly protruding flange 162, and the outer cover 114 is provided with a clearance opening 116. The operating part 160 extends out of the clearance opening 116 to facilitate operation by the operator to apply external force to the operating part 160. The flange 162 is located inside the outer cover 114 and its size is larger than that of the clearance opening 116, so that the end face of the flange 162 can abut against the periphery of the clearance opening 116 to limit the operation part 160 and prevent the operation part 160 from falling out of the clearance opening 116.
[0089] Reference Figure 4 and Figure 5 The locking hook 150 has an inclined guide surface 151. By setting the guide surface 151, when the fastening member 140 moves from the position of being unfastened from the door hook 130 to being fastened to the door hook 130, it is easy for the fastening member 140 and the locking hook 150 to enter the locking state.
[0090] Reference Figure 3 The fastening member 140 has an upward-opening fork 141. The fastening port of the door hook 130 is fastened to the fork 141. Since the opening of the fork 141 of the fastening member 140 is set upward, when it is necessary to release the fastening port of the door hook 130 from the fork 141, a downward force needs to be applied to the fork to rotate the opening of the fork downward. Usually, the door hook 130 is connected to the handle. Therefore, when opening the door, a downward force needs to be applied to the door handle 121, which conforms to the human body's force application habits, is simple to operate, and improves the user experience.
[0091] The fastening member 140 has a pivot portion 142, a fork portion 143, and a locking portion 144.
[0092] The pivoting part 142 is pivotally mounted on the main unit 110.
[0093] Specifically, refer to Figure 3The main unit 110 is provided with a pivot shaft 117, and a boss 118 is provided on the side wall of the pivot shaft 117. The pivot part 142 is provided with a mounting hole 145, and a guide groove 146 is provided in the inner wall surface of the mounting hole 145 along its axial direction. During installation, the guide groove 146 is aligned with the boss 118, the pivot part 142 is fitted onto the pivot shaft 117, and the pivot part 142 slides close to the main unit 110, so that the boss 118 protrudes from the guide groove 146. The pivot part 142 is rotated so that the end face of the boss 118 facing the main unit 110 abuts against the end face of the pivot part 142 away from the main unit 110. The boss 118 and the guide groove 146 are staggered along the rotation direction of the locking hook 150, which restricts the movement of the pivot part 142 in the direction away from the main unit 110 and prevents the pivot part 142 from falling off the pivot part 142. In addition, the boss 118 provides a predetermined rotational friction force to the pivot 142, so that the pivot 142 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.
[0094] The fork portion 143 and the locking portion 144 are both connected to the pivot portion 142 and are spaced apart circumferentially along the pivot portion 142. The fork portion 143 engages with the door hook 130, thereby locking the door 120 relative to the host 110, thus completing the second locking mechanism in the above embodiment. The locking portion 144 engages with the lock hook 150, thereby locking the pivot portion 142, thus completing the first locking mechanism in the above embodiment.
[0095] It should be noted that the locking portion 144 has a locking surface 147 that extends radially along the pivot axis 117 of the pivot portion 142 and axially along the pivot axis 117. The locking surface 147 can abut against the locking hook 150, thereby locking the pivot portion 142. Since the locking surface 147 extends radially along the pivot axis 117, wear and deformation of the locking portion 144 due to prolonged locking and unlocking are avoided.
[0096] In some embodiments, the pivot portion 142, the fork portion 143, and the locking portion 144 may be integrated into one unit.
[0097] Specifically, the locking part 144 is provided with a locking groove, and the locking hook 150 is adapted to extend into the locking groove to lock with the fastener 140. This allows the user to slide the operating part 160 when the food needs to be opened to take out the food after cooking. The operating part 160 can drive the locking hook 150 to slide in the left and right direction until the locking hook 150 slides 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 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 117. 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.
[0098] It should be noted that the principle by which the locking hook 150 engages with the locking groove to lock the fastener 140 is that the locking groove has a locking surface 147, and the locking hook 150 has a locking engagement end face. By engaging the locking surface 147 with the locking engagement end face, the fastener 140 can be locked. Specifically, there are various ways to form the locking end face. In the above embodiment, a locking groove is formed. Of course, in other embodiments, the locking part 144 can also be a locking arm extending radially along the pivot axis 117, with the locking surface 147 formed on the locking arm. This allows the locking engagement end face of the locking hook 150 to engage with the locking surface 147, thereby locking the fastener 140. In addition, there are various forms of forming the locking surface 147, and this application does not limit this.
[0099] In addition, there are various ways to form the locking groove. For example, the locking part 144 can be machined by punching.
[0100] In some embodiments, such as Figures 3 to 5 As shown, the cooking appliance 100 may also include a first reset member 170.
[0101] The first reset member 170 can be elastically connected between the locking hook 150 and the main unit 110. The first reset member 170 can be used to drive the locking hook 150 to remain in the first position.
[0102] To prevent the first reset member 170 from becoming misaligned and affecting the reset effect, the main unit 110 is provided with a connecting post. One end of the first reset member 170 can be connected to the connecting post, and the other end of the first reset member 170 can be connected to the locking hook 150. The first reset member 170 can be in a compressed state, and its elastic restoring force can drive the locking hook 150 to slide towards the first position. Alternatively, in other embodiments, the first reset member 170 can be in a stretched state, and its elastic restoring force can drive the locking hook 150 to slide towards the first position.
[0103] Specifically, the first reset element 170 can be a spring or an elastic sleeve, without limitation.
[0104] In actual operation, when the user presses the operating part 160, the locking hook 150 can slide from the first position to the second position. During this process, the first reset member 170 located between the connecting post and the locking hook 150 is continuously compressed, and the elastic force applied by the first reset member 170 to the locking hook 150 continuously increases until the locking hook 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.
[0105] After the door is opened, the user can release the operating part 160. After the human force applied to the locking hook 150 to overcome the elastic force disappears, the locking hook 150 can slide from the second position to the first position. During this process, the first reset member 170 located between the connecting post and the locking hook 150 continuously extends, and the elastic force applied by the first reset member 170 to 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. The operation is simple.
[0106] The cooking appliance 100 provided in this application embodiment, through the setting of the first reset member 170 and the guiding effect of the guide post 115, allows the locking hook 150 to automatically return to the first position after the user releases the operating part 160. The connecting post connects to the first reset spring, making 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 processing precision requirements are low, and it is easy to install.
[0107] Specifically, the type of the first reset member 170 can be selected based on the external force applied to the operating part 160. For example, in the embodiments of this application, when pressure is applied to the operating part 160, a compression spring is selected as the first reset member 170. The operating part 160 is subjected to pressure and moves 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 operating part 160 is removed, the operating part 160 returns to the first position under the action of the elastic force of the first reset member 170. In other embodiments, when tension is applied to the operating part 160, a tension spring is selected as the first reset member 170. The operating part 160 is subjected to tension and moves 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 operating part 160 is removed, the operating part 160 returns to the first position under the action of the elastic force of the first reset member 170.
[0108] The cooking appliance 100 provided in this embodiment, through the aforementioned guide post 115 and the design of the first reset member 170, achieves sliding unlocking and elastic reset of the locking hook 150. The guide post 115, the first reset member 170, and the connecting post cooperate with each other, ensuring that the mechanical performance of the locking hook 150 is not significantly affected during cyclic reciprocating motion, thereby increasing the reliability of the entire child lock structure.
[0109] In some embodiments, refer to Figure 4 The cooking appliance 100 also includes a second reset member 180, 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 180 and the door hook 130 on the fastener 140 are opposite.
[0110] By setting a second reset member 180 connected between the fastener 140 and the host 110, when the door is opened, the torques of the second reset member 180 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 180 after the external force acting on the door body 120 is removed. The structure is simple and easy to operate.
[0111] Specifically, the second reset member 180 can be a torsion spring. Of course, in other embodiments, the second reset member 180 can be selected as needed, and this application does not limit it.
