The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present disclosure and are not to be construed as limiting the present disclosure.

[0072] The present disclosure discloses a door assembly of a cooking appliance 100 .

[0073] The door assembly of the cooking appliance 100 according to an embodiment of the present disclosure will be described below with reference to FIG. 1 to FIG. 20 .

[0074] In some embodiments, as shown in FIG. 1 to FIG. 4 , the door assembly of the cooking appliance 100 includes a door body 110 , a handle base 120 , a lock hook 130 , a handle 140 , an operating member 150 and a transmission member 160 .

[0075] The door body 110 can be used to block the cooking cavity to provide a closed cooking environment for food. The door body 110 can be provided with a transparent window, which can be used to observe the status of the food being cooked.

[0076] The handle base 120 is installed on the door body 110 .

[0077] The connection method between the handle base 120 and the door body 110 may include but is not limited to a snap connection, a threaded connection or a riveted connection. For example, in some embodiments, the connection method between the handle base 120 and the door body 110 is a threaded connection.

[0078] The locking hook 130 is pivotally mounted on the door body 110 between a first position and a second position about a first axis, the first axis is 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, and the locking hook 130 is suitable for locking with the main unit 170 of the cooking appliance 100 when in the first position, and is suitable for unlocking with the main unit 170 of the cooking appliance 100 when in the second position.

[0079] The lock hook 130 can be used to lock the door body 110 and the host 170. The lock hook 130 can be made of metal or plastic. For example, in some embodiments, the lock hook 130 is made of plastic, wherein the plastic material can include but is not limited to PBT (Polybutylene terephthalate), PP (Polypropylene), POM (Polyformaldehyde) or PC (Polycarbonate), etc.

[0080] As shown in Figures 3-4, a portion of the lock hook 130 can be located inside the door body 110 and the handle base 120, and another portion of the lock hook 130 can pass through the back panel of the door body 110 and extend into the main unit 170 of the cooking appliance 100, so that at least a portion of the lock hook 130 is locked with the main unit 170 of the cooking appliance 100.

[0081] It can be understood that the door body 110 can define the activity space of the lock hook 130, and the lock hook 130 can rotate back and forth in the activity space. The activity space can include a first position and a second position. The first position can be the position of the lock hook 130 at this time when the door body 110 and the host 170 are locked, and the second position can be the position of the lock hook 130 at this time when the door body 110 and the host 170 are unlocked. In other words, the lock hook 130 can rotate back and forth between the first position and the second position, thereby realizing the locking and unlocking between the door body 110 and the host 170.

[0082] The handle 140 is mounted on the handle base 120 .

[0083] As shown in Figures 9 and 10, the handle seat 120 may include two handle seats 120 arranged at intervals, and the handle 140 may be installed between the two handle seats 120. The connection method between the handle 140 and the handle seat 120 may include but is not limited to a snap connection, a threaded connection or a riveted connection, etc. For example, in some embodiments, the connection method between the handle 140 and the handle seat 120 is a threaded connection.

[0084] The operating member 150 is slidably mounted on the handle 140 .

[0085] As shown in Figures 1-2 and 9-12, the operating member 150 can be slidably installed on the handle 140 along the front-rear direction. At least part of the operating member 150 can be located inside the handle 140, and the rest of the operating member 150 can extend outside the handle 140.

[0086] The transmission member 160 is pivotally mounted on the handle 140 around a second axis, the operating member 150 abuts against the transmission member 160, and one of the transmission member 160 and the lock hook 130 passes through the handle base 120 to be power-coupled with the other, and the operating member 150 is used to drive the transmission member 160 to rotate to drive the lock hook 130 to rotate from the first position to the second position.

[0087] The transmission member 160 can be used to transmit power between the operating member 150 and the lock hook 130. As shown in Figures 1-2 and 11-12, the transmission member 160 can be rotatably installed inside the handle 140. The transmission member 160 can be a rotating rod. One end of the transmission member 160 can stop the operating member 150, and the other end of the transmission member 160 can be power-coupled with the lock hook 130.

[0088] It can be understood that the transmission member 160 can pass through the handle base 120 to be dynamically coupled to the lock hook 130, or the lock hook 130 can pass through the handle base 120 to be dynamically coupled to the transmission member 160. For example, in some embodiments, as shown in Figures 1-4 and 11-12, the lock hook 130 can pass through the handle base 120 to be dynamically coupled to the transmission member 160.

[0089] It should be noted that the lock hook 130 structure disclosed in the present invention can be a safety lock for the cooking appliance 100, that is, the above-mentioned lock hook 130 is the first lock of the cooking appliance 100, and the user cannot release the first lock by directly pulling the door. The cooking appliance 100 itself has an elastic door lock, which is the second lock of the cooking appliance 100. The user can use a smaller force to pull the handle 140 outward to release the elastic door lock.

[0090] In actual implementation, as shown in Figures 3-4 and 17-20, when the food is cooked and the door body 110 needs to be opened to take out the food, the door body 110 is in a closed state and the lock hook 130 is in the first position. The user can press the operating member 150 to drive the transmission member 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 holds the handle 140, and can pull the door body 110 outward with a small force. As the second lock is released, the door body 110 and the main unit 170 of the cooking appliance 100 can also be unlocked accordingly.

[0091] The door assembly of the cooking appliance 100 provided in the embodiment of the present disclosure, through the arrangement of the above-mentioned lock hook 130, operating member 150 and transmission member 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 110, helping to improve the safety and reliability of the entire cooking appliance 100.

[0092] In some embodiments, as shown in Figures 1-4 and 11-12, the first axis can be perpendicular to the second axis, one of the transmission member 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 be slidably engaged with the slide groove 161, and the pin 133 and the slide groove 161 are rotatably connected.

[0093] In some embodiments, as shown in Figures 1-4 and 11-12, the transmission member 160 may be provided with a waist-shaped slide groove 161, and the lock hook 130 may be provided with a pin 133. The transmission member 160 rotates around the second axis, and the power is transmitted to the lock hook 130 through the slide groove 161 and the pin 133, driving the lock hook 130 to rotate around the first axis. During the rotation, the position of the slide groove 161 located on the transmission member 160 is constantly changing, so that the pin 133 slides along the waist-shaped slide groove 161. During the rotation, based on the fact that the first axis and the second axis are not in the same straight line, the pin 133 slides along the waist-shaped slide groove 161 to compensate for the tolerance between different rotation trajectories.

[0094] In other embodiments, the lock hook 130 may be provided with a slide groove 161, and the transmission member 160 may be provided with a pin shaft 133. The transmission member 160 rotates around the second axis. The power is transmitted to the lock hook 130 through the slide groove 161 and the pin shaft 133, driving the lock hook 130 to rotate around the first axis. During the rotation process, the position of the slide groove 161 located at the lock hook 130 is constantly changing, causing the pin shaft 133 to slide along the slide groove 161.

[0095] The door assembly of the cooking utensil 100 provided in the embodiment of the present disclosure realizes the rotational connection and sliding fit between the transmission member 160 and the lock hook 130 through the arrangement of the above-mentioned slide groove 161 and the pin shaft 133, which facilitates the appropriate adjustment of the positioning size during use and compensates for the displacement tolerance caused by the non-coaxiality of the first axis and the second axis during the relative rotation.

[0096] In some embodiments, as shown in Figures 1-2 and 13-14, the operating member 150 may be provided with a first driving bevel 151, and the transmission member 160 may be provided with a second driving bevel 162 that is in contact with the first driving bevel 151, and the normals of the first driving bevel 151 and the second driving bevel 162 may form an acute angle with the second axis.

[0097] In actual implementation, as shown in Figures 1-2 and 13-14, when the user opens the door, the user can press the operating member 150 to make the first driving inclined surface 151 of the operating member 150 slide backward, driving the second driving inclined surface 162 that is in contact with the first driving inclined surface 151 to rotate downward, driving the entire transmission member 160 to rotate around the second axis. The transmission member 160 can drive the lock hook 130 to rotate from the first position around the first axis through the cooperation between the pin shaft 133 and the slide groove 161 until the lock hook 130 reaches the second position, the first lock is released, the user holds the handle 140, and can pull the door body 110 outward with a small force. As the second lock is released, the door body 110 and the main unit 170 of the cooking appliance 100 can also be unlocked accordingly.

[0098] The door assembly of the cooking utensil 100 provided in the embodiment of the present disclosure realizes that the operating member 150 drives the transmission member 160 to rotate and thereby drives the lock hook 130 to rotate and unlock by setting the above-mentioned first driving inclined surface 151 and second driving inclined surface 162. By utilizing the characteristics of the inclined surface, the sliding stroke of the operating member 150 is cleverly converted into the rotation stroke of the transmission member 160, so that the overall design of the child lock structure tends to be simple and efficient, and easy to assemble and disassemble, which saves assembly time and reduces product costs.

[0099] In some embodiments, as shown in FIG. 1 to FIG. 4 , the door assembly of the cooking appliance 100 may further include: a first restoring member 101 .

[0100] The first restoring member 101 can be elastically connected between the transmission member 160 and the handle base 120 , and the first restoring member 101 can be used to drive the transmission member 160 to reset.

[0101] As shown in Figures 1-4 and Figures 13-14, the transmission member 160 can be provided with a connecting column, the first reset member 101 can be sleeved on the connecting column of the transmission member 160, and the first reset member 101 can be compressed between the transmission member 160 and the handle seat 120.

[0102] The first restoring member 101 may be a spring or an elastic rubber sleeve, which is not limited here.

[0103] In actual implementation, when the user presses the operating member 150, the transmission member 160 can rotate around the second axis, driving the lock hook 130 to rotate around the first axis. During this process, the first reset member 101 is continuously compressed, and the elastic force applied by the first reset member 101 to the transmission member 160 continues to increase until the lock hook 130 overcomes the elastic force and slides to the second position. When the user releases the operating member 150 and the manpower applied to the operating member 150 to overcome the elastic force disappears, the first reset member 101 continues to extend, and the elastic force applied by the first reset member 101 to the transmission member 160 continues to decrease, and the transmission member 160 rotates around the second axis until the transmission member 160 returns to its initial position.

[0104] The door assembly of the cooking utensil 100 provided in the embodiment of the present disclosure, through the provision of the above-mentioned 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 part, and low processing precision requirements, which is convenient for installation.

[0105] In some embodiments, as shown in Figures 5 to 8, the handle 140 may be provided with a rotating support 142 and a stop portion 143, and the transmission member 160 may be rotatably installed on the rotating support 142. When the transmission member 160 rotates around the rotating support 142 to the target position, the stop portion 143 may stop the transmission member 160.

[0106] In some embodiments, as shown in Figures 5 and 7, the rotating support 142 can be generally columnar, the transmission member 160 can be mounted on the rotating support 142, the handle 140 can be provided with multiple raised reinforcement ribs, and the stop portion 143 can be provided on the reinforcement ribs. When the transmission member 160 rotates around the rotating support 142 to the initial position, the stop portion 143 can stop the transmission member 160.

[0107] In other embodiments, as shown in Figures 6 and 8, the rotating support 142 can be generally annular, the transmission member 160 can be embedded in the rotating support 142, the handle 140 can be provided with multiple raised reinforcement ribs, the stop portion 143 can be provided on the reinforcement ribs, and the stop portion 143 can also be provided on the rotating support 142. When the transmission member 160 rotates around the rotating support 142 to the initial position, the stop portion 143 can stop the transmission member 160, and when the transmission member 160 rotates around the rotating support 142 to the unlocked position, the stop portion 143 can also stop the transmission member 160.

[0108] It is understandable that if the handle 140 is not provided with the stop portion 143, when the door body 110 is in the closed state and the lock hook 130 is in the first position, when the user presses the operating member 150, the lock hook 130 is driven to reach the second position to complete the unlocking. However, since there is no status prompt structure, the user continues to press the operating member 150 with a large force, and the transmission member 160 continues to press the lock hook 130, which may cause the lock hook 130 to damage the child lock device and fail accordingly.

[0109] In the case where the handle 140 is provided with a stop portion 143, when the user presses the operating member 150 to unlock, after the lock hook 130 reaches the second position from the first position, the transmission member 160 stops at the stop portion 143, and the lock hook 130 does not continue to rotate, that is, the lock hook 130 does not exceed the second position, which serves to prompt the unlocking position, and after the user releases the operating member 150, the transmission member 160 does not rotate excessively, so as to prevent the user from applying too much force to damage the child lock device, thereby ensuring the reliability and practicality of the child lock structure.

[0110] In some embodiments, as shown in FIG. 5 - FIG. 6 and FIG. 11 - FIG. 12 , the handle 140 includes a first handle cover 141 and a second handle cover 144 .

[0111] The first handle cover 141 may be provided with a stopper 143 ; the second handle cover 144 may be mounted on a front surface of the first handle cover 141 , and at least a portion of the operating member 150 may extend from the second handle cover 144 .

[0112] As shown in Figures 5-6 and 11-12, the first handle cover 141 is installed between the two handle seats 120, the two ends of the second handle cover 144 are respectively connected to the two handle seats 120, and the second handle cover 144 is located on the front of the first handle cover 141. An installation cavity is defined between the first handle cover 141 and the second handle cover 144, and the transmission member 160 is arranged in the installation cavity. The first handle cover 141 is provided with a mounting bolt on the side facing the second handle cover 144, and the second handle cover 144 is provided with a threaded hole on the side facing the first handle cover 141. The transmission member 160 is provided with a corresponding avoidance groove. The first handle cover 141 and the second handle cover 144 are connected by the mounting bolt and the threaded hole, and the mounting bolt can pass through the avoidance groove and be threadedly matched with the threaded hole.

[0113] During processing, the avoidance groove is reserved with extra space, that is, the inner wall surface of the avoidance groove is spaced apart from the outer wall surface of the mounting bolt to ensure that the transmission member 160 can rotate and avoid the threaded hole and the mounting bolt from restricting the rotation of the transmission member 160.

[0114] As shown in FIG5-6, a stopper 143 is provided on the inner side of the first handle cover 141. When the operating member 150 is pressed to drive the transmission member 160 to rotate, when the transmission member 160 rotates to a certain extent, the stopper 143 stops the transmission member 160, restricting the transmission member 160 from continuing to rotate.

[0115] In some embodiments, as shown in Figures 11-12, the handle 140 may be provided with an avoidance opening, the operating member 150 may be slidably installed in the avoidance opening, the operating member 150 may have a limiting boss 152, the limiting boss 152 may be located on the inner side of the handle 140, and the size of the operating member 150 at the limiting boss 152 may be larger than the size of the avoidance opening.

[0116] The operating member 150 may have an inwardly concave operating surface, or the operating member 150 may have an outwardly convex operating surface to facilitate user manipulation.

[0117] It is understandable that if the operating member 150 is not provided with the limiting boss 152, in other words, the maximum outer diameter of the operating member 150 is not greater than the maximum diameter of the avoidance opening, when the lock hook 130 rotates to reset, the lock hook 130 has a certain impact speed at this time. Considering that the transmission member 160 and the operating member 150 are stopped, 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 avoidance opening.

[0118] In the case where the operating member 150 is provided with a limiting boss 152, that is, the maximum outer diameter of the operating member 150 is larger than the maximum diameter of the avoidance opening, when the lock hook 130 rotates and resets, 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 avoidance opening, increasing the reliability and stability of the connection between the operating member 150 and the handle 140.

[0119] In some embodiments, as shown in FIG. 11 and FIG. 12 , the door assembly of the cooking appliance 100 may further include a second restoring member 102 .

[0120] The second restoring member 102 may be elastically connected between the operating member 150 and the handle 140 , and the second restoring member 102 may be used to drive the operating member 150 to reset.

[0121] As shown in FIG. 11 and FIG. 12 , the first handle cover 141 may be provided with a connecting column, the second restoring member 102 may be sleeved on the connecting column of the first handle cover 141 , and the second restoring member 102 may be compressed between the operating member 150 and the first handle cover 141 .

[0122] In actual implementation, as shown in Figures 11 and 12, when the user presses the operating member 150, the second reset member 102 is continuously compressed, and the elastic force applied by the second reset member 102 to the operating member 150 continues to increase until the lock 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 body 110 outward, that is, unlock the second lock of the cooking appliance 100. After opening the door, the user can release the operating member 150, and the second reset member 102 continues to extend, and the elastic force applied by the second reset member 102 to the operating member 150 continues to decrease until the operating member 150 returns to its initial position.

[0123] The second restoring member 102 may be a spring or an elastic rubber sleeve, etc., which is not limited here.

[0124] The door assembly of the cooking utensil 100 provided in the embodiment of the present disclosure, through the provision of the above-mentioned 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 part, and low processing precision requirements, which is convenient for installation.

[0125] In some embodiments, as shown in FIG. 2 , FIG. 10 and FIG. 12 , the transmission member 160 and the locking hook 130 may be symmetrically arranged at both ends of the operating member 150 .

[0126] In this embodiment, as shown in Figures 2, 10 and 12, the operating member 150 can be arranged in the center of the handle 140, and two lock hooks 130 and two transmission members 160 can be provided, respectively arranged at the two ends of the operating member 150, and the distances between the lock hooks 130 and the transmission members 160 at both ends and the operating member 150 are equal, that is, the force arms at both ends are equal. When the user presses the operating member 150, the transmission members 160 at both ends can be driven to rotate around the second axis at the same time, thereby driving the lock hooks 130 at both ends to rotate around the first axis.

[0127] The door assembly of the cooking utensil 100 provided in the embodiment of the present disclosure realizes double locking at both ends of the door body 110 through the design of 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 solid and reliable, reducing the torque that the door body 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 body 110 more uniform, thereby extending the service life of the child lock structure.

[0128] In some embodiments, as shown in FIG. 1-6 , the handle base 120 may be provided with a guide slot 121 , and both ends of the lock hook 130 may pass through the guide slot 121 to be dynamically coupled to the operating member 150 and extend from the back of the handle base 120 .

At least 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, pass through the door body 110, and finally extend from the back panel of the door body 110.

[0130] The door assembly of the cooking utensil 100 provided in the embodiment of the present disclosure realizes the assembly of the lock hook 130 in the handle base 120 through the provision of the above-mentioned guide groove 121, ensuring that the lock 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 lock hook 130, making the entire child lock structure more flexible during operation and more convenient for users to operate.

[0131] In some embodiments, as shown in FIG. 15-FIG . 16 , the locking hook 130 includes a locking hook arm 132 and a hook body 131 .

[0132] The locking hook arm 132 is pivotally mounted on the door body 110 around a first axis, and one end of the locking hook arm 132 can be dynamically 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.

[0133] In actual implementation, as shown in Figures 15 and 16, the hook body 131 can face upward, and the user can press the operating member 150 to drive the transmission member 160 to rotate around the second axis, thereby driving one end of the lock hook 130 power-coupled with the transmission member 160 to lift, and the lock hook arm 132 to rotate around the first axis, driving the hook body 131 connected to the other end of the lock hook arm 132 to rotate downward and slowly disengage from the main unit 170 until the lock hook 130 reaches the second position. At this time, the first lock of the cooking appliance 100 is released, and the user holds the handle 140 and can pull the door body 110 outward with a small force. As the second lock is released, the door body 110 and the main unit 170 of the cooking appliance 100 can also be unlocked accordingly.

[0134] The door assembly of the cooking appliance 100 provided in the embodiment of the present disclosure realizes the power coupling connection between the lock hook 130 and the transmission member 160 and the locking with the host 170 through the arrangement of the above-mentioned lock hook arm 132 and the hook body 131. The structural layout is reasonable and the functional division is clear. Without affecting the normal locking and unlocking functions of the lock hook 130, the entire machine tends to be lightweight and small.

[0135] In some embodiments, as shown in FIG. 15-FIG . 16 , the locking hook 130 further includes a supporting seat 134 .

[0136] The support base 134 may be mounted on the door body 110 . The support base 134 may have a rotating shaft 135 . The locking hook 130 may be pivotally mounted on the rotating shaft 135 .

[0137] The locking hook 130 can be fixedly connected to the door body 110 through the support seat 134, wherein the method of fixing the support seat 134 and the door body 110 includes but is not limited to bolt connection, riveting or snap connection, etc. For example, in some embodiments, the method of fixing the support seat 134 and the door body 110 is bolt connection.

[0138] In this embodiment, as shown in Figures 15 and 16, the support seat 134 can be fixed in the door body 110, the support seat 134 can be installed on the side of the lock hook arm 132 close to the handle 140, and the rotating shaft 135 of the support seat 134 can pass through the lock hook arm 132, and the lock hook 130 can rotate around the rotating shaft 135 after being driven.

[0139] The door assembly of the cooking utensil 100 provided in the embodiment of the present disclosure realizes the installation of the lock hook 130 on the door body 110 and the fixed assembly of the rotating shaft 135 through the setting of the above-mentioned support base 134, ensuring that the lock hook 130 rotates in a guided manner after being driven, making the rotation process of the lock hook 130 more stable, and improving the stability of the entire child lock structure.

[0140] In some embodiments, as shown in FIG. 1-FIG . 4 and FIG. 15 - FIG. 16 , the door assembly of the cooking appliance 100 may further include a third restoring member 103 .

[0141] The third restoring member 103 may be elastically connected between the lock hook 130 and the door body 110 , and the third restoring member 103 may be used to drive the lock hook 130 to remain in the first position.

The elastic force of the third reset member 103 can keep the lock hook 130 and the host 170 in a locked state.

[0143] The third restoring member 103 may be a spring or an elastic rubber sleeve, etc., which is not limited here.

[0144] In this embodiment, as shown in Figures 3 and 4, when the user presses the operating member 150, the lock hook 130 can rotate from the first position to the second position. During this process, the third reset member 103 is continuously compressed, and the elastic force applied by the third reset member 103 to the lock hook 130 continues to increase until the lock 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 body 110 outward, thereby unlocking the second lock of the cooking appliance 100.

[0145] After opening the door, the user can release the operating member 150. After the manpower applied to the lock hook 130 to overcome the elastic force disappears, the lock hook 130 can rotate from the second position to the first position. During this process, the third reset member 103 continues to extend, and the elastic force applied by the third reset member 103 to the lock hook 130 continues to decrease until the lock hook 130 returns to the first position. When the user needs to close the door body 110, based on the design of the elastic connection, the user can directly hold the handle 140 and push the door body 110 toward the host 170 until the lock hook 130 and the host 170 are locked again, that is, the user's door closing action can realize the automatic locking of the child lock.

[0146] The door assembly of the cooking utensil 100 provided in the embodiment of the present disclosure, through the provision of the above-mentioned first return member 101 and the guiding function of the guide column, allows the lock hook 130 to automatically return to the first position after the user releases the operating member 150. The first return member 101 is not easy to fall off and is durable. At the same time, it has a simple structure, a single assembly part, and low processing precision requirements, which is convenient for installation.

[0147] In some embodiments, as shown in FIG. 2 and FIG. 16 , the door assembly of the cooking appliance 100 further includes a driving portion 190 and an unlocking assembly 180 .

[0148] The driving portion 190 may be connected to the lock hook 130 ; the unlocking assembly 180 may be installed on the handle base 120 , and the unlocking assembly 180 may be in contact with the driving portion 190 , and the unlocking assembly 180 may be used to drive the driving portion 190 to rotate.

As the second lock is released, the door body 110 and the main unit 170 of the cooking appliance 100 can also be unlocked accordingly.

[0161] The door assembly of the cooking appliance 100 provided in the embodiment of the present disclosure, through the unlocking structure design of the lower-opening door and the method of setting a lock on the opposite side of the pivot axis, makes the entire cooking appliance 100 occupy a smaller space, improves the volume utilization, and facilitates the overall layout; at the same time, the pull-down door body 110 can be used as a transition for freshly cooked hot food, making it convenient for users to take and put food, thereby optimizing the overall machine experience.

[0162] The present disclosure also discloses a cooking appliance 100 .

[0163] In some embodiments, as shown in FIG. 17 to FIG. 20 , the cooking appliance 100 includes: a main unit 170 and any one of the door assemblies described above.

[0164] The main unit 170 has a cooking cavity.

[0165] The host 170 can be used to cook food through temperature control and time control. The host 170 can include an inner cavity and an outer cover. The inner cavity can define a cooking cavity, which can serve as a container and cooperate with the door assembly to provide a closed environment for food.

[0166] The door body 110 of the door assembly is openably mounted on the main unit 170 . The lock hook 130 is locked with the main unit 170 of the cooking appliance 100 in a first position and unlocked from the main unit 170 of the cooking appliance 100 in a second position.

[0167] It should be noted that the cooking utensil 100 may include but is not limited to a microwave oven, an oven, or a steam-bake combination machine, etc. For example, in some embodiments, as shown in Figures 17 to 20, the cooking utensil 100 is a microwave oven.

[0168] In actual implementation, 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 lock hook 130 rotate around the first axis from the first position until the lock hook 130 reaches the second position. At this time, the first lock of the cooking appliance 100 is released, and the user holds the handle 140 and pulls the door body 110 outward with a small force. As the second lock is released, the door body 110 and the main unit 170 can also be unlocked accordingly. After the user opens the door body 110, he takes out the cooked food. Then the user can directly hold the handle 140 and push the upper frame of the door body 110 toward the main unit 170 until the lock hook 130 and the main unit 170 are locked again.

[0169] The cooking appliance 100 provided in the embodiment of the present disclosure, through the arrangement of the above-mentioned door assembly and the use of a double-layer lock design, requires the user to complete a two-step unlocking process to open the door, thereby reducing the risk of children opening the door and coming into contact with heated food and drinks and being scalded; 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.

[0170] In some embodiments, as shown in FIG. 3-FIG . 4 , the host 170 may be provided with a locking block 172 , and the locking hook 130 may be locked with the back surface of the locking block 172 when in the first position.

[0171] In this embodiment, as shown in Figures 3-4, a locking groove can be provided on the front panel 171 of the main unit 170, and a locking block 172 can be provided on the edge of the locking groove and located on the side of the front panel 171 close to the cooking cavity. When the locking hook 130 is locked with the main unit 170, the hook body 131 can be extended into the locking groove and overlapped with the locking block 172 for locking. At this 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 be separated from the locking block 172. At this time, the locking hook 130 can be in the second position.

[0172] The cooking utensil 100 provided in the embodiment of the present disclosure realizes the locking between the lock hook 130 and the door body 110 by setting the above-mentioned locking block 172 and utilizing the overlapping connection between the hook body 131 and the locking block 172, so that the connection structure is more concise and lightweight, and cost control is achieved 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.

[0173] In some embodiments, as shown in FIG. 3-FIG . 4 , the front surface of the locking block 172 and the back surface of the hook body 131 of the locking hook 130 may be provided with a guide surface.

[0174] It is understandable that if the backs of the locking block 172 and the hook body 131 are both blocks without guide surfaces, when the user opens or closes the door, the corners of the locking block 172 and the corners of the hook body 131 will easily hit each other, and at this time, the hook body 131 will be difficult to detach from or lock the locking block 172.

[0175] In actual implementation, when the user needs to close the door body 110, the user can directly hold the handle 140 and push the door body 110 toward the host 170. During the locking process, the guide surface on the back of the hook body 131 stops at the guide surface on the front of the lock block 172. Based on the characteristics of the inclined surface, the hook body 131 can be smoothly pushed into the host 170, that is, the front of the hook body 131 fits with the back of the lock block 172, and the lock hook 130 and the host 170 are locked again, that is, the user's door closing action can realize the automatic locking of the child lock.

[0176] The cooking utensil 100 provided in the embodiment of the present disclosure, through the setting of the above-mentioned guide surface, utilizes the characteristics of the inclined surface to minimize the interference force caused by the surface features of the hook body 131 and the locking block 172 during the locking and unlocking process, greatly reducing the difficulty of opening and closing the door for the user, while improving the smoothness of the operation.
