[0076] 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.

[0077] This application discloses a door assembly for a cooking appliance 100.

[0078] The following is for reference. Figures 1-20 Describes a door assembly of a cooking appliance 100 according to an embodiment of this application.

[0079] In some embodiments, such as Figures 1-4 As shown, the door assembly of the cooking appliance 100 includes: door body 110, handle base 120, lock hook 130, handle 140, operating component 150, and transmission component 160.

[0080] The door 110 can be used to seal the cooking cavity to provide a closed cooking environment for food. The door 110 can be equipped with a transparent window, which can be used to observe the status of the food being cooked.

[0081] The handle base 120 is installed on the door body 110.

[0082] The connection between the handle base 120 and the door body 110 can be, but is not limited to, snap-fit ​​connection, threaded connection or riveting. For example, in some embodiments, the connection between the handle base 120 and the door body 110 is a threaded connection.

[0083] The locking hook 130 is pivotally mounted on the door body 110 between a first position and a second position about a first axis parallel to the pivot axis of the door body 110. At least a portion of the locking hook 130 extends from the back panel of the door body 110. In the first position, the locking hook 130 is adapted to lock with the main unit 170 of the cooking appliance 100, and in the second position, the locking hook 130 is adapted to unlock with the main unit 170 of the cooking appliance 100.

[0084] The locking hook 130 can be used to lock the door body 110 and the main unit 170. The locking hook 130 can be made of metal or plastic. For example, in some embodiments, the locking hook 130 is made of plastic. The plastic material can include, but is not limited to, PBT (Polybutylene terephthalate), PP (Polypropylene), POM (Polyformaldehyde), or PC (Polycarbonate).

[0085] like Figures 3-4 As shown, a portion of the locking hook 130 may be located within the door body 110 and the handle seat 120, and another portion of the locking hook 130 may penetrate through the back panel of the door body 110 and extend into the main unit 170 of the cooking appliance 100, thereby locking at least a portion of the locking hook 130 with the main unit 170 of the cooking appliance 100.

[0086] It is understandable that the door body 110 can limit the movement space of the locking hook 130, which can rotate back and forth within this movement space. This movement space can include a first position and a second position. The first position can be the position of the locking hook 130 when the door body 110 and the host 170 are locked, and the second position can be the position of the locking hook 130 when the door body 110 and the host 170 are unlocked. In other words, the locking hook 130 can rotate back and forth between the first position and the second position to achieve locking and unlocking between the door body 110 and the host 170.

[0087] Handle 140 is installed on handle base 120.

[0088] like Figures 9-10As shown, the handle base 120 may include two spaced apart, and the handle 140 may be installed between the two handle bases 120. The connection method between the handle 140 and the handle base 120 may include, but is not limited to, snap connection, threaded connection or riveting. For example, in some embodiments, the connection method between the handle 140 and the handle base 120 is a threaded connection.

[0089] The operating component 150 is slidably mounted on the handle 140.

[0090] like Figures 1-2 and Figures 9-12 As shown, the operating member 150 can be slidably mounted on the handle 140 in the front-back direction. At least a portion of the operating member 150 can be located inside the handle 140, and the remaining portion of the operating member 150 can extend outside the handle 140.

[0091] The transmission element 160 is pivotally mounted on the handle 140 about a second axis. The operating element 150 abuts against the transmission element 160. One of the transmission element 160 and the locking hook 130 passes through the handle seat 120 to be power-coupled to the other. The operating element 150 is used to drive the transmission element 160 to rotate in order to drive the locking hook 130 to rotate from a first position to a second position.

[0092] The transmission element 160 can be used to transmit power between the operating element 150 and the locking hook 130, such as Figures 1-2 and Figures 11-12 As shown, the transmission component 160 can be rotatably installed inside the handle 140. The transmission component 160 can be a rotating rod. One end of the transmission component 160 can stop the operating component 150, and the other end of the transmission component 160 can be power-coupled to the locking hook 130.

[0093] It is understood that the transmission element 160 can penetrate the handle base 120 to be power-coupled with the locking hook 130, or the locking hook 130 can penetrate the handle base 120 to be power-coupled with the transmission element 160, for example, in some embodiments, such as Figures 1-4 and Figures 11-12 As shown, the locking hook 130 can pass through the handle base 120 to be power-coupled with the transmission component 160.

[0094] It should be noted that the locking hook 130 structure of this application can be a safety lock for the cooking appliance 100. That is, the locking hook 130 is the first lock of the cooking appliance 100. The user cannot unlock the first lock by directly pulling the door. The cooking appliance 100 itself has a resilient door lock, which is the second lock of the cooking appliance 100. The user can unlock the resilient door lock by pulling the handle 140 outward with a small force.

[0095] In actual implementation, such as Figures 3-4 and Figures 17-20As shown, when the food is cooked and the door 110 needs to be opened to remove it, the door 110 is closed and the lock hook 130 is in the first position. The user can press the operating component 150 to drive the transmission component 160 to rotate around the second axis, thereby driving the lock hook 130 to rotate around the first axis until the lock hook 130 reaches the second position. At this time, the first lock of the cooking appliance 100 is released. The user can hold the handle 140 and pull the door 110 outward with a small force. With the release of the second lock, the door 110 and the main unit 170 of the cooking appliance 100 can also be unlocked accordingly.

[0096] The door assembly of the cooking appliance 100 provided in this application embodiment, through the setting of the aforementioned locking hook 130, operating member 150 and transmission member 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 110, thus helping to improve the safety and reliability of the entire cooking appliance 100.

[0097] In some embodiments, such as Figures 1-4 and Figures 11-12 As shown, the first axis can be perpendicular to the second axis. One of the transmission component 160 and the locking hook 130 can be provided with a slide groove 161, and the other can be provided with a pin 133. The pin 133 can slide with the slide groove 161, and the pin 133 and the slide groove 161 are rotatably connected.

[0098] In some implementations, such as Figures 1-4 and Figures 11-12 As shown, the transmission component 160 may be provided with a waist-shaped groove 161, and the locking hook 130 may be provided with a pin 133. The transmission component 160 rotates around the second axis, and the power is transmitted to the locking hook 130 through the groove 161 and the pin 133, driving the locking hook 130 to rotate around the first axis. During the rotation, the position of the groove 161 in the transmission component 160 is constantly changing, causing the pin 133 to slide along the waist-shaped groove 161. During the rotation, since the first axis and the second axis are not on the same straight line, the pin 133 slides along the waist-shaped groove 161 to compensate for the tolerance between different rotation trajectories.

[0099] In other embodiments, the locking hook 130 may be provided with a slide groove 161, and the transmission member 160 may be provided with a pin 133. The transmission member 160 rotates around the second axis, and the power is transmitted to the locking hook 130 through the slide groove 161 and the pin 133, driving the locking hook 130 to rotate around the first axis. During the rotation, the position of the slide groove 161 on the locking hook 130 is constantly changing, causing the pin 133 to slide along the slide groove 161.

[0100] The door assembly of the cooking appliance 100 provided in this application embodiment realizes the rotational connection and sliding fit between the transmission component 160 and the locking hook 130 through the above-mentioned sliding groove 161 and pin 133, which facilitates the appropriate adjustment of the positioning size during use, and at the same time makes up for the displacement tolerance caused by the misalignment of the first axis and the second axis during relative rotation.

[0101] In some embodiments, such as Figures 1-2 and Figures 13-14 As shown, the operating member 150 may be provided with a first driving inclined surface 151, and the transmission member 160 may be provided with a second driving inclined surface 162 that fits against the first driving inclined surface 151. The normals of the first driving inclined surface 151 and the second driving inclined surface 162 may form an acute angle with the second axis.

[0102] In actual implementation, such as Figures 1-2 and Figures 13-14 As shown, when the user opens the door, the user can press the operating component 150, causing the first driving inclined surface 151 of the operating component 150 to slide backward, driving the second driving inclined surface 162, which is in contact with the first driving inclined surface 151, to rotate downward, causing the entire transmission component 160 to rotate around the second axis. The transmission component 160 can drive the locking hook 130 to rotate around the first axis from the first position through the cooperation between the pin 133 and the slide groove 161 until the locking hook 130 reaches the second position, the first lock is released, the user holds the handle 140 and can pull the door 110 outward with a small force. With the release of the second lock, the door 110 and the main unit 170 of the cooking appliance 100 can also be unlocked accordingly.

[0103] The door assembly of the cooking appliance 100 provided in this application embodiment, through the setting of the first driving inclined surface 151 and the second driving inclined surface 162, enables the operating component 150 to drive the transmission component 160 to rotate, thereby driving the lock hook 130 to rotate and unlock. By utilizing the characteristics of the inclined surface, the sliding stroke of the operating component 150 is cleverly converted into the rotation stroke of the transmission component 160, making the overall design of the child lock structure simple and efficient, easy to assemble and disassemble, saving assembly time and reducing product costs.

[0104] In some embodiments, such as Figures 1-4 As shown, the door assembly of the cooking appliance 100 may further include: a first reset member 101.

[0105] The first reset member 101 can be elastically connected between the transmission member 160 and the handle seat 120. The first reset member 101 can be used to drive the transmission member 160 to reset.

[0106] like Figures 1-4 and Figures 13-14As shown, the transmission component 160 may be provided with a connecting post, the first reset component 101 may be sleeved on the connecting post of the transmission component 160, and the first reset component 101 may be compressed between the transmission component 160 and the handle seat 120.

[0107] The first reset element 101 can be a spring or an elastic sleeve, and there are no restrictions on it.

[0108] In actual operation, when the user presses the operating component 150, the transmission component 160 can rotate around the second axis, driving the locking hook 130 to rotate around the first axis. During this process, the first reset component 101 is continuously compressed, and the elastic force exerted by the first reset component 101 on the transmission component 160 continuously increases until the locking hook 130 overcomes the elastic force and slides to the second position. When the user releases the operating component 150, after the human force applied to the operating component 150 to overcome the elastic force disappears, the first reset component 101 continuously extends, and the elastic force exerted by the first reset component 101 on the transmission component 160 continuously decreases. The transmission component 160 rotates around the second axis until the transmission component 160 returns to the initial position.

[0109] The door assembly of the cooking appliance 100 provided in this application embodiment, through the setting of the first reset member 101, allows the transmission member 160 to automatically reset after the user releases the operating member 150. The first reset member 101 is not easy to fall off and is durable. At the same time, it has a simple structure, a single assembly, low requirements for processing precision, and is easy to install.

[0110] In some embodiments, such as Figures 5-8 As shown, the handle 140 may be provided with a rotating support 142 and a stop part 143. The transmission member 160 can be rotatably mounted on the rotating support 142. When the transmission member 160 rotates around the rotating support 142 to the target position, the stop part 143 can stop the transmission member 160.

[0111] In some implementations, such as Figure 5 and Figure 7 As shown, the rotating support 142 can be generally cylindrical, the transmission component 160 can be sleeved on the rotating support 142, the handle 140 can be provided with multiple raised reinforcing ribs, and the stop part 143 can be provided on the reinforcing ribs. When the transmission component 160 rotates around the rotating support 142 to the initial position, the stop part 143 can stop the transmission component 160.

[0112] In other implementations, such as Figure 6 and Figure 8As shown, the rotating support 142 can be generally annular, the transmission component 160 can be embedded in the rotating support 142, the handle 140 can be provided with multiple raised reinforcing ribs, the stop part 143 can be provided on the reinforcing ribs, and the stop part 143 can also be provided on the rotating support 142. When the transmission component 160 rotates around the rotating support 142 to the initial position, the stop part 143 can stop the transmission component 160, and when the transmission component 160 rotates around the rotating support 142 to the unlocked position, the stop part 143 can also stop the transmission component 160.

[0113] It is understandable that if the handle 140 does not have a stop part 143, when the door 110 is closed and the lock hook 130 is in the first position, when the user presses the operating part 150, the lock hook 130 will have reached the second position and completed the unlocking. However, since there is no status indication structure, if the user continues to press the operating part 150 with greater force, the transmission part 160 will continue to press the lock hook 130, which may cause the lock hook 130 to be damaged and the child lock device to malfunction accordingly.

[0114] When the handle 140 is equipped with a stop 143, when the user presses the operating member 150 to unlock, after the locking hook 130 moves from the first position to the second position, the transmission member 160 stops at the stop 143, and the locking hook 130 will not continue to rotate, that is, the locking hook 130 will not cross the second position, which serves to indicate the unlocking position. Furthermore, after the user releases the operating member 150, the transmission member 160 will not rotate excessively to prevent the user from applying too much force and damaging the child lock device, thus ensuring the reliability and practicality of the child lock structure.

[0115] In some embodiments, such as Figures 5-6 and Figures 11-12 As shown, the handle 140 includes: a first handle cover 141 and a second handle cover 144.

[0116] The first handle cover 141 may be provided with a stop portion 143; the second handle cover 144 may be installed on the front of the first handle cover 141, and at least a portion of the operating member 150 may extend from the second handle cover 144.

[0117] like Figures 5-6 and Figures 11-12As shown, the first handle cover 141 is installed between two handle seats 120. The two ends of the second handle cover 144 are connected to the two handle seats 120 respectively, and the second handle cover 144 is located on the front of the first handle cover 141. A mounting cavity is defined between the first handle cover 141 and the second handle cover 144. The transmission component 160 is arranged in the mounting cavity. The side of the first handle cover 141 facing the second handle cover 144 is provided with a mounting bolt. The side of the second handle cover 144 facing the first handle cover 141 is provided with a threaded hole. The transmission component 160 is provided with a corresponding clearance groove. The first handle cover 141 and the second handle cover 144 are connected by the mounting bolt and the threaded hole. The mounting bolt can pass through the clearance groove and the threaded hole for threaded engagement.

[0118] The clearance groove is designed with extra space during machining, meaning that the inner wall of the clearance groove is spaced apart from the outer wall of the mounting bolt, to ensure that the transmission component 160 can rotate and to prevent the threaded hole and mounting bolt from restricting the rotation of the transmission component 160.

[0119] like Figures 5-6 As shown, the inner side of the first handle cover 141 is provided with a stop part 143. When the pressing operation member 150 drives the transmission member 160 to rotate, when the transmission member 160 rotates to a certain extent, the stop part 143 stops the transmission member 160 and restricts the transmission member 160 from continuing to rotate.

[0120] In some embodiments, such as Figures 11-12 As shown, the handle 140 may be provided with a clearance opening, and the operating member 150 may be slidably installed in the clearance opening. The operating member 150 may have a limiting boss 152, which may be located inside the handle 140, and the size of the operating member 150 at the limiting boss 152 may be larger than the size of the clearance opening.

[0121] The operating element 150 may have an inwardly recessed operating surface, or the operating element 150 may have an outwardly protruding operating surface, to facilitate user operation.

[0122] It is understandable that if the operating member 150 is not provided with a limiting boss 152, in other words, the maximum outer diameter of the operating member 150 is not greater than the maximum diameter of the clearance opening, when the locking hook 130 rotates to reset, the locking hook 130 has a certain impact speed. Considering that the transmission member 160 and the operating member 150 are mutually restrained, the impact force may be transmitted to the entire operating member 150 through the transmission member 160, causing the operating member 150 to be pushed out of the clearance opening.

[0123] When the operating member 150 is equipped with a limiting boss 152, that is, the maximum outer diameter of the operating member 150 is greater than the maximum diameter of the clearance opening, when the locking hook 130 rotates to reset, the impact force pushes the operating member 150 outward. At this time, the limiting boss 152 can stop against the inner wall of the second handle cover 144, thereby restricting the entire operating member 150 within the clearance opening, increasing the reliability and stability of the connection between the operating member 150 and the handle 140.

[0124] In some embodiments, such as Figures 11-12 As shown, the door assembly of the cooking appliance 100 may further include a second reset member 102.

[0125] The second reset member 102 can be elastically connected between the operating member 150 and the handle 140, and the second reset member 102 can be used to drive the operating member 150 to reset.

[0126] like Figures 11-12 As shown, the first handle cover 141 may be provided with a connecting post, the second reset member 102 may be sleeved on the connecting post of the first handle cover 141, and the second reset member 102 may be compressed between the operating member 150 and the first handle cover 141.

[0127] In actual implementation, such as Figures 11-12 As shown, when the user presses the operating component 150, the second reset component 102 is continuously compressed, and the elastic force exerted by the second reset component 102 on the operating component 150 continuously increases until the locking hook 130 rotates 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 pull the handle 140 to pull the door 110 outward, thereby unlocking the second lock of the cooking appliance 100. After opening the door, the user can release the operating component 150, and the second reset component 102 continuously extends, and the elastic force exerted by the second reset component 102 on the operating component 150 continuously decreases until the operating component 150 returns to its initial position.

[0128] The second reset element 102 can be a spring or an elastic sleeve, etc., and there are no restrictions here.

[0129] The door assembly of the cooking appliance 100 provided in this application embodiment, through the setting of the second reset member 102, allows the operating member 150 to automatically return to its initial position after the user releases the operating member 150. The second reset member 102 is not easy to fall off and is durable. At the same time, it has a simple structure, a single assembly, low requirements for processing precision, and is easy to install.

[0130] In some embodiments, such as Figure 2 , Figure 10 and Figure 12 As shown, the transmission component 160 and the locking hook 130 can be arranged symmetrically at both ends of the operating component 150.

[0131] In this embodiment, such as Figure 2 , Figure 10 and Figure 12 As shown, the operating component 150 can be arranged in the center of the handle 140. Two locking hooks 130 and two transmission components 160 can be provided, respectively arranged at both ends of the operating component 150. The distances from the locking hooks 130 and transmission components 160 at both ends to the operating component 150 are equal, that is, the lever arms at both ends are equal. When the user presses the operating component 150, the transmission components 160 at both ends can be driven to rotate around the second axis at the same time, thereby driving the locking hooks 130 at both ends to rotate around the first axis.

[0132] The door assembly of the cooking appliance 100 provided in this application embodiment achieves double locking at both ends of the door 110 through the symmetrical arrangement of the child lock structures at both ends. Compared with the design of locking at one end, the entire child lock structure is more robust and reliable, reducing the torque that the door 110 needs to bear. At the same time, the symmetrical arrangement design maximizes the synchronous locking and unlocking of the child locks at both ends, making the force on the entire door 110 more uniform and extending the service life of the child lock structure.

[0133] In some embodiments, such as Figures 1-6 As shown, the handle base 120 may be provided with a guide groove 121, and the two ends of the locking hook 130 may pass through the guide groove 121 to be dynamically coupled to the operating member 150, and extend from the back of the handle base 120.

[0134] In this embodiment, such as Figures 1-6 As shown, the guide groove 121 can be clearance-fitted with the lock hook 130. One end of the lock hook 130 is poweredly coupled to the transmission component 160, and the other end of the lock hook 130 can be locked with the host 170. At least a part of the lock hook 130 is located in the handle seat 120, and the other part of the lock hook 130 can pass through the guide groove 121, penetrate the door body 110, and finally extend out from the back plate of the door body 110.

[0135] The door assembly of the cooking appliance 100 provided in this application embodiment, through the setting of the above-mentioned guide groove 121, realizes the assembly of the locking hook 130 in the handle seat 120, ensuring that the locking hook 130 will not shake arbitrarily and interfere with other components during rotation. At the same time, the guide groove 121 does not completely lock the position of the locking hook 130, making the entire child lock structure more flexible in operation and more convenient for user operation.

[0136] In some embodiments, such as Figures 15-16 As shown, the lock hook 130 includes a lock hook arm 132 and a hook body 131.

[0137] The locking hook arm 132 is pivotally mounted on the door body 110 about a first axis, and one end of the locking hook arm 132 can be poweredly coupled to the operating member 150; the hook body 131 can be connected to the other end of the locking hook arm 132, and the hook body 131 can be used to lock with the host 170.

[0138] In actual implementation, such as Figures 15-16 As shown, the hook 131 can face upwards. The user can press the operating component 150 to drive the transmission component 160 to rotate around the second axis, thereby driving one end of the locking hook 130, which is poweredly coupled to the transmission component 160, to lift up. The locking hook arm 132 rotates around the first axis, driving the hook 131 connected to the other end of the locking hook arm 132 to rotate downwards and slowly disengage from the main unit 170 until the locking hook 130 reaches the second position. At this time, the first lock of the cooking appliance 100 is released. The user can hold the handle 140 and pull the door 110 outwards with a small force. With the release of the second lock, the door 110 and the main unit 170 of the cooking appliance 100 can also be unlocked accordingly.

[0139] The door assembly of the cooking appliance 100 provided in this application embodiment, through the above-mentioned locking hook arm 132 and hook body 131, realizes the power coupling connection between the locking hook 130 and the transmission component 160 and the locking with the main unit 170. The structure layout is reasonable and the functional areas are clear. Without affecting the normal locking and unlocking functions of the locking hook 130, the whole machine tends to be lightweight and miniaturized.

[0140] In some embodiments, such as Figures 15-16 As shown, the locking hook 130 also includes a support base 134.

[0141] The support base 134 can be installed on the door body 110, and the support base 134 can have a pivot 135, on which the locking hook 130 can be pivotally installed.

[0142] The locking hook 130 can be fixedly connected to the door body 110 through the support base 134. The fixed connection between the support base 134 and the door body 110 includes, but is not limited to, bolt connection, riveting or snap connection. For example, in some embodiments, the fixed connection between the support base 134 and the door body 110 is a bolt connection.

[0143] In this embodiment, such as Figures 15-16 As shown, the support seat 134 can be fixed inside the door body 110. The support seat 134 can be installed on the side of the hook arm 132 near the handle 140. The pivot 135 of the support seat 134 can pass through the hook arm 132. The hook 130 can rotate around the pivot 135 after being driven.

[0144] The door assembly of the cooking appliance 100 provided in this application embodiment, through the setting of the support seat 134, realizes the installation of the locking hook 130 on the door body 110 and the fixed assembly of the rotating shaft 135, ensuring that the locking hook 130 rotates in a guided manner after being driven, making the rotation process of the locking hook 130 more stable and improving the stability of the entire child lock structure.

[0145] In some embodiments, such as Figures 1-4 and Figures 15-16 As shown, the door assembly of the cooking appliance 100 may further include a third reset member 103.

[0146] The third reset member 103 can be elastically connected between the lock hook 130 and the door body 110. The third reset member 103 can be used to drive the lock hook 130 to remain in the first position.

[0147] like Figures 15-16 As shown, the locking hook 130 may be provided with a guide post, and the third reset member 103 may be sleeved on the guide post. The third reset member 103 may be located on the side of the rotating shaft 135 away from the hook body 131, and the third reset member 103 may be in a compressed state. The elastic force of the third reset member 103 may keep the locking hook 130 locked to the main unit 170.

[0148] The third reset component 103 can be a spring or an elastic sleeve, etc., and there are no restrictions here.

[0149] In this embodiment, such as Figures 3-4 As shown, when the user presses the operating component 150, the locking hook 130 can rotate from the first position to the second position. During this process, the third reset component 103 is continuously compressed, and the elastic force applied by the third reset component 103 to the locking hook 130 continuously increases until the locking hook 130 overcomes the elastic force and rotates to the second position. At this time, the first lock of the cooking appliance 100 is released, and the user can pull the handle 140 to pull the door 110 outward, thereby unlocking the second lock of the cooking appliance 100.

[0150] After the door is opened, the user can release the operating component 150. Once the force applied to the locking hook 130 to overcome the elasticity is removed, the locking hook 130 can rotate from the second position to the first position. During this process, the third reset component 103 continuously extends, and the elastic force applied by the third reset component 103 to the locking hook 130 continuously decreases until the locking hook 130 returns to the first position. When the user needs to close the door 110, based on the elastic connection design, the user can directly grasp the handle 140 and push the door 110 toward the host 170 until the locking hook 130 and the host 170 lock again. That is, the user's closing action can realize the automatic locking of the child lock.

[0151] The door assembly of the cooking appliance 100 provided in this application embodiment, through the setting of the first reset member 101 and the guiding effect of the guide column, allows the locking hook 130 to automatically return to the first position after the user releases the operating member 150. The first reset member 101 is not easy to fall off and is durable. At the same time, it has a simple structure, a single assembly, low requirements for processing precision, and is easy to install.

[0152] In some embodiments, such as Figure 2 and Figure 16 As shown, the door assembly of the cooking appliance 100 also includes a drive unit 190 and an unlocking unit 180.

[0153] The drive unit 190 can be connected to the locking hook 130; the unlocking component 180 can be installed on the handle base 120, and the unlocking component 180 can contact the drive unit 190, and the unlocking component 180 can be used to drive the drive unit 190 to rotate.

[0154] Among them, such as Figure 2 and Figure 16 As shown, the drive unit 190 is connected to the locking hook 130. The drive unit 190 can be a plate-shaped structure, a frustum-shaped structure, or other shapes.

[0155] The connection between the drive unit 190 and the locking hook 130 may include, but is not limited to, bonding, welding, threaded connection or integral molding. For example, in some embodiments, the connection between the drive unit 190 and the locking hook 130 is integral molding.

[0156] In actual implementation, such as Figure 2 and Figure 16 As shown, the top of the unlocking component 180 contacts the bottom of the drive unit 190. When the user does not need the child lock structure or the operating component 150 fails, the user can operate the unlocking component 180 to drive the drive unit 190 to rotate upward, thereby driving the hook body 131 of the lock hook 130 to rotate downward, so as to unlock the lock hook 130 from the main unit 170.

[0157] The door assembly of the cooking appliance 100 provided in this application embodiment, through the setting of the unlocking assembly 180 and the drive unit 190, can unlock the lock hook 130 and the main unit 170 through the unlocking assembly 180 and the drive unit 190 when the user does not need the child lock structure or the operating part 150. It is equivalent to a backup operating mechanism, providing double protection for unlocking the lock hook 130 and the main unit 170, and providing multiple options for users who do not need a child lock.

[0158] In some embodiments, such as Figure 2 and 6 As shown, the unlocking component 180 includes a nut 181 and an unlocking bolt 182.

[0159] Nut 181 can be installed on handle base 120; unlocking bolt 182 can be threaded to nut 181, and the end of unlocking bolt 182 can contact drive unit 190.

[0160] Among them, such as Figure 2 Figure 6 As shown, nut 181 is installed inside handle base 120 and is located below drive unit 190. Unlocking bolt 182 can be threadedly connected to nut 181, and the end of unlocking bolt 182 passes through nut 181 and contacts the bottom surface of drive unit 190. The head of unlocking bolt 182 extends from the bottom of handle base 120 for easy operation by the user.

[0161] In actual implementation, such as Figure 2 Figure 6 As shown, when the user does not need the child lock structure or the operating part 150 fails, the user can use the tool to turn the unlocking bolt 182, so that the unlocking bolt 182 moves upward relative to the nut 181. During the movement, the unlocking bolt 182 abuts against the driving part 190 and pushes the driving part 190 to rotate upward, thereby driving the lock hook 130 to unlock, and the unlocking bolt 182 can be held in this position.

[0162] The door assembly of the cooking appliance 100 provided in this application embodiment, through the setting of the nut 181 and the unlocking bolt 182, can keep the lock hook 130 in the second position after the lock hook 130 and the main unit 170 are unlocked by using the unlocking bolt 182, so as to facilitate the subsequent opening of the door 110. At the same time, the head of the unlocking bolt 182 extends from the bottom of the handle seat 120, which is convenient for the user to operate.

[0163] In some embodiments, such as Figures 17-20 As shown, the pivot axis of the door body 110 can be located on the lower frame of the door body 110, and the locking hook 130 can be adapted to lock the upper part of the main unit 170.

[0164] In some embodiments, when the food needs to be removed from the door 110 after cooking, the user can press the operating member 150. The operating member 150 slides backward and drives the transmission member 160 to rotate in the front-back direction. The transmission member 160 can drive the locking hook 130 to rotate in the left-right direction until the locking hook 130 rotates from the first position to the second position. At this time, the first lock of the cooking appliance 100 is released. The user can hold the handle 140 and pull the door 110 with a small force. The upper frame of the door 110 can be separated from the main unit 170 of the cooking appliance 100, and the upper frame of the door 110 can rotate downward around the pivot axis. With the release of the second lock, the door 110 and the main unit 170 of the cooking appliance 100 can also be unlocked accordingly.

[0165] In other embodiments, the pivot axis of the door 110 can be located on the left or right side frame of the door 110. The user can press the operating member 150, which slides backward and drives the transmission member 160 to rotate in the front-back direction. The transmission member 160 can drive the locking hook 130 to rotate in the up-down direction until the locking hook 130 rotates from the first position to the second position. At this time, the first lock of the cooking appliance 100 is released. The user can hold the handle 140 and pull the door 110 with a small force. The door 110 rotates to the left or right around the pivot axis. With the release of the second lock, the door 110 and the main unit 170 of the cooking appliance 100 can also be unlocked accordingly.

[0166] The door assembly of the cooking appliance 100 provided in this application embodiment, through the above-mentioned bottom-opening door unlocking structure design, combined with the method of setting a lock on the opposite side of the pivot axis, makes the entire cooking appliance 100 occupy less space, improves volume utilization, and facilitates overall layout; at the same time, the pull-down door 110 can be used as a transition for freshly cooked hot food, making it convenient for users to take and put away food, thereby optimizing the overall user experience.

[0167] This application also discloses a cooking utensil 100.

[0168] In some embodiments, such as Figures 17-20 As shown, the cooking appliance 100 includes: a main unit 170 and a door assembly as described above.

[0169] The main unit 170 has a cooking cavity.

[0170] The main unit 170 can be used to cook food through temperature control and time control. The main unit 170 may include an inner cavity and an outer cover. The inner cavity can define a cooking chamber, which can act as a container and cooperate with a door assembly to provide a closed environment for the food.

[0171] The door body 110 of the door assembly is installed on the main unit 170 in an openable and closable manner. The locking hook 130 is locked to the main unit 170 of the cooking appliance 100 in the first position and unlocked to the main unit 170 of the cooking appliance 100 in the second position.

[0172] 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 Figures 17-20 As shown, cooking appliance 100 is a microwave oven.

[0173] In actual operation, the user can put the food to be cooked into the cooking cavity. After the food is cooked, the user can press the operating part 150 to make the locking hook 130 rotate around the first axis from the first position until the locking hook 130 reaches the second position. At this time, the first lock of the cooking appliance 100 is released. The user can hold the handle 140 and pull the door 110 outward with a small force. With the release of the second lock, the door 110 and the main unit 170 can also be unlocked accordingly. After the user opens the door 110, he / she takes out the cooked food. Then the user can directly hold the handle 140 and push the upper frame of the door 110 toward the main unit 170 until the locking hook 130 and the main unit 170 lock again.

[0174] The cooking appliance 100 provided in this application embodiment, through the setting of the above-mentioned door component and the use of a double-lock design, requires the user to complete two steps to unlock in order to open the door, reducing the risk of children opening and touching heated food and beverages and being burned; at the same time, the overall structure of the child lock is simple, easy and quick to operate, and low in cost, which greatly improves the practicality and economy of the device.

[0175] In some embodiments, such as Figures 3-4 As shown, the main unit 170 may be provided with a locking block 172, and the locking hook 130 can be locked with the back of the locking block 172 when in the first position.

[0176] In this embodiment, such as Figures 3-4 As shown, the front panel 171 of the main unit 170 can be provided with a locking groove, and the locking block 172 can be provided on the edge of the locking groove and located on the side of the front panel 171 near the cooking cavity. When the locking hook 130 is locked with the main unit 170, the hook body 131 can extend into the locking groove and engage with the locking block 172 to lock, at which time the locking hook 130 can be in the first position; when the locking hook 130 is unlocked from the main unit 170, the hook body 131 can disengage from the locking block 172, at which time the locking hook 130 can be in the second position.

[0177] The cooking appliance 100 provided in this application embodiment, through the setting of the locking block 172, uses the hook body 131 to overlap with the locking block 172 to achieve locking between the locking hook 130 and the door body 110, making the connection structure simpler and lighter, and achieving cost control without affecting the reliability of the child lock structure; at the same time, the locking block 172 enhances the structural strength of the locking area and improves the stability of the locking structure.

[0178] In some embodiments, such as Figures 3-4 As shown, both the front of the locking block 172 and the back of the hook body 131 of the locking hook 130 can be provided with guide surfaces.

[0179] It is understandable that if the back of both the lock block 172 and the hook body 131 are blocks without guide surfaces, when the user opens or closes the door, the edges of the lock block 172 and the hook body 131 may easily jam together, making it difficult for the hook body 131 to disengage from or lock the lock block 172.

[0180] In actual operation, when a user needs to close the door 110, the user can directly grasp the handle 140 and push the door 110 toward the host 170. During the locking process, the guide surface on the back of the hook 131 abuts against the guide surface on the front of the lock block 172. Based on the characteristics of the inclined surface, the hook 131 can be smoothly pushed into the host 170, that is, the front of the hook 131 fits against the back of the lock block 172, and the hook 130 locks with the host 170 again. In other words, the user's closing action can realize the automatic locking of the child lock.

[0181] The cooking appliance 100 provided in this application embodiment, through the setting of the above-mentioned guide surface, utilizes the characteristics of the inclined surface to minimize the interference force of the surface features of the hook body 131 and the locking block 172 on the locking and unlocking process, greatly reducing the difficulty for users to open and close the door, while improving the smoothness of operation.
