[0046] 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.

[0047] This application discloses a door assembly for a cooking appliance 100.

[0048] The following is for reference. Figures 1-10 Describes a door assembly of a cooking appliance 100 according to an embodiment of this application.

[0049] In some embodiments, such as Figure 1 As shown, the door assembly of the cooking appliance 100 includes: a door body 110, a locking hook 120, a reset member 140, and an operating part 130.

[0050] The door 110 can be used to seal the cooking cavity 161 to provide a closed cooking environment for food. The door 110 can have a transparent window, which can be used to observe the status of the food being cooked. A handle can be installed on the outer panel of the door 110, which can be used to facilitate the user to pull the door 110.

[0051] The locking hook 120 is rotatably mounted on the first frame 112 of the door 110 between a first position and a second position about a first axis, and at least a portion of the locking hook 120 extends from the back panel of the door 110. The first axis is parallel to the normal of the side of the first frame 112. In the first position, the locking hook 120 is adapted to lock with the main unit 160 of the cooking appliance 100, and in the second position, the locking hook 120 is adapted to unlock with the main unit 160 of the cooking appliance 100.

[0052] The locking hook 120 can be used to lock the door body 110 and the main unit 160. The locking hook 120 can be made of metal or plastic. For example, in some embodiments, the locking hook 120 is made of plastic. The plastic material can include, but is not limited to, PP (Polypropylene), POM (Polyformaldehyde), or PC (Polycarbonate).

[0053] like Figure 1 As shown, a portion of the locking hook 120 may be located inside the door 110, and another portion of the locking hook 120 may penetrate through the back panel of the door 110 and extend into the main unit 160 of the cooking appliance 100, thereby locking at least a portion of the locking hook 120 with the main unit 160 of the cooking appliance 100.

[0054] Understandably, the locking hook 120 can rotate around the first axis. Specifically, when the locking hook 120 is locked to the main unit 160 of the cooking appliance 100, the locking hook 120 is in the first position of the first frame 112. The locking hook 120 can rotate around the first axis to the second position of the first frame 112 until the locking hook 120 is unlocked from the main unit 160 of the cooking appliance 100.

[0055] The reset member 140 is elastically connected between the lock hook 120 and the door body 110, and the reset member 140 is used to drive the lock hook 120 to remain in the first position.

[0056] like Figure 2 As shown, the door frame 111 may be provided with a connecting post. One end of the reset member 140 may be connected to the connecting post, and the other end of the reset member 140 may be connected to the lock hook 120. The reset member 140 may be in a stretched state, and the tension of the reset member 140 may keep the lock hook 120 locked to the main unit 160.

[0057] The reset element 140 can be a spring or an elastic sleeve, and there are no restrictions on it.

[0058] The operating part 130 is connected to the locking hook 120. The operating part 130 is at least used to drive the locking hook 120 to rotate from a first position to a second position. At least a portion of the operating part 130 is spaced apart from the first axis.

[0059] The connection between the operating part 130 and the locking hook 120 may include, but is not limited to, interference fit, integral molding or bonding. For example, in some embodiments, the connection between the operating part 130 and the locking hook 120 is an interference fit.

[0060] It should be noted that the locking hook structure of this application can be a safety lock for the cooking appliance 100. That is, the above-mentioned locking hook structure 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 outward with a small force.

[0061] In actual operation, the operating part 130 can be at least partially exposed to the outside for easy user operation. When the food is cooked and the door 110 needs to be opened to take out the food, the door 110 is closed and the locking hook 120 is in the first position. The user can move the operating part 130 to make the locking hook 120 rotate around the first axis. During this process, the reset member 140 located between the connecting post and the locking hook 120 extends continuously until the locking hook 120 reaches the second position. At this time, the first lock of the cooking appliance 100 is released. The user can hold the handle and pull the door 110 outward with a small force. With the release of the second lock, the door 110 and the main unit 160 of the cooking appliance 100 can also be unlocked accordingly.

[0062] After the door is opened, the user can release the operating part 130. After the human force applied to the lock hook 120 to overcome the elastic force disappears, the lock hook 120 can rotate from the second position to the first position around the first axis. During this process, the reset member 140 located between the connecting post and the lock hook 120 continuously shortens, and the elastic force applied by the reset member 140 to the lock hook 120 continuously decreases until the lock hook 120 returns to the first position. When the user needs to close the door 110, based on the elastic connection design, the user can directly hold the handle and push the first frame 112 toward the host 160 until the lock hook 120 and the host 160 lock again. That is, the user's closing action can realize the automatic locking of the child lock.

[0063] 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.

[0064] 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.

[0065] In this embodiment, at least a portion of the locking hook 120 extends from the back panel of the door 110. Compared to the above-mentioned solution where the locking hook 120 extends from the side panel of the door 110, impurities and dirt are less likely to enter the door 110 during daily use, making it easier to clean the cooking utensils 100. Secondly, the operating part 130 is located above the door 110. Since the operating part 130 does not directly face the user and is relatively high, children cannot easily reach the operating part 130, thus ensuring the safety of the child lock structure.

[0066] The door assembly of the cooking appliance 100 provided in this application embodiment, through the setting of the aforementioned locking hook 120, operating part 130 and reset member 140, adds a mechanical child lock structure to the original door opening system, ensuring that the child lock must be turned to release it before the door can be opened, thus preventing children from touching heated food and being burned after opening the door 110, and helping to improve the safety and reliability of the entire cooking appliance 100.

[0067] In some embodiments, such as Figures 1-3 As shown, the first frame 112 can be a frame opposite to the pivot axis of the door body 110.

[0068] In this embodiment, such as Figures 1-3 As shown, the pivot axis can be the rotation axis between the door body 110 and the main unit 160. The first frame 112 can be detachably connected to the main unit 160. The pivot axis and the first frame 112 can be set opposite to each other. During the unlocking process of the door body 110, the user moves the operation part 130. The operation part 130 can drive the lock hook 120 to rotate around the pivot axis of the door body 110 until the lock hook 120 rotates from the first position to the second position. The child lock structure is unlocked. At this time, the handle on the door body 110 is pulled, and the first frame 112 can be disengaged from the main unit 160 of the cooking appliance 100. The door body 110 can rotate around the pivot axis, that is, the first frame 112 can rotate around the pivot axis.

[0069] It should be noted that when the door assembly is a pull-down door, the first frame 112 is horizontal, and correspondingly, the first axis is vertical; when the door assembly is a side-sliding door, the first direction is vertical, and correspondingly, the first axis is horizontal.

[0070] The door assembly of the cooking appliance 100 provided in this application embodiment, through the setting of the rotation direction of the aforementioned locking hook 120, and the method of setting a lock on the opposite side of the pivot axis, allows the locking hook 120 to rotate back and forth around a direction perpendicular to the pivot axis. The user can complete the initial unlocking by turning the operating part 130, reducing the difficulty of operation; at the same time, the overall structure has high cyclic strength and strong durability, thereby extending the service life.

[0071] In some embodiments, such as Figure 1 and Figure 3 As shown, the pivot axis of the door body 110 can be located on the lower frame of the door body 110, the first frame 112 can be the upper frame of the door body 110, and the lock hook 120 can be installed on the first frame 112 by rotating around the vertical.

[0072] In actual implementation, since the pivot axis of the door 110 is located on the lower frame of the door 110, and considering the user's opening force, the handle can be installed near the upper frame of the door 110. When the food is cooked and the door 110 needs to be opened to take out the food, the user can turn the operating part 130. The operating part 130 can drive the locking hook 120 to rotate in the up and down direction until the locking hook 120 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 and pull the door 110 with a small force. The first frame 112 can be disengaged from the main unit 160 of the cooking appliance 100, and the first frame 112 can rotate downward around the pivot axis. With the release of the second lock, the door 110 and the main unit 160 of the cooking appliance 100 can also be unlocked accordingly.

[0073] Alternatively, the pivot axis of the door 110 can be located on the left or right side frame of the door 110, and the first side frame 112 can be located on the opposite side of the pivot axis. In actual operation, the user can move the operating part 130, which can drive the locking hook 120 to rotate in the left and right directions until the locking hook 120 rotates from the initial position to the unlocked position. At this time, the first lock of the cooking appliance 100 is released, and the user can hold the handle and pull the door 110 with a small force. The first side frame 112 can be disengaged from the main unit 160 of the cooking appliance 100, and the first side frame 112 can rotate to the left or right around the pivot axis. With the release of the second lock, the door 110 and the main unit 160 of the cooking appliance 100 can also be unlocked accordingly.

[0074] The door assembly of the cooking appliance 100 provided in this application embodiment, through the above-mentioned bottom-opening door unlocking structure design, 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.

[0075] In some embodiments, such as Figure 2 , Figure 7 and Figure 9 As shown, the back panel of the first frame 112 may be provided with a back panel clearance groove 115, and the lock hook 120 may extend out from the back panel clearance groove 115; one of the lock hook 120 and the door body 110 may be provided with a lock hook pivot 151, and the other may be provided with a shaft hole 123 that pivotally engages with the lock hook pivot 151.

[0076] It is understandable that, such as Figure 2 As shown, the locking hook 120 can pass through the back panel slide groove, and at least a part of the locking hook 120 can extend out of the back panel slide groove to reach the host 160 and lock with the host 160. The door body 110 can be provided with a locking hook pivot 151, and the locking hook 120 can be provided with a pivot hole 123. Alternatively, the locking hook 120 can be provided with a locking hook pivot 151, and the door body 110 can be provided with a pivot hole 123.

[0077] The door assembly of the cooking appliance 100 provided in this application embodiment achieves directional rotation of the locking hook 120 through the setting of the back plate clearance groove 115, the locking hook pivot 151 and the shaft hole 123, making the rotation of the locking hook 120 more stable; at the same time, the positioning accuracy is high and the wear is small during the rotation, which has a positive effect on extending the service life of the parts.

[0078] In some embodiments, such as Figure 1 As shown, the door body 110 may include: a door frame 111 and a door shell 113.

[0079] The back panel of the door frame 111 may be provided with a back panel clearance groove 115, and the door frame 111 may be provided with one of a lock hook pivot 151 and a pivot hole 123; the door housing 113 may be installed on the outside of the door frame 111, and the door housing 113 may have a clearance opening 114, the lock hook 120 may pass through the clearance opening 114, and the lock hook 120 may be connected to the operating part 130 located outside the door housing 113.

[0080] In this embodiment, such as Figure 1 and Figure 4As shown, the locking hook 120 can pass through the back panel slide groove of the door frame 111, and a part of the locking hook 120 can extend into the main unit 160 of the cooking appliance 100. Another part of the locking hook 120 can extend out of the clearance opening 114 of the door shell 113, and the operating part 130 can be nested on the locking hook 120 extending out of the clearance opening 114. At this time, the operating part 130 is located above the clearance opening 114. When the user moves the operating part 130, the locking hook 120 can rotate back and forth within the limitation range of the back panel slide groove.

[0081] The door assembly of the cooking appliance 100 provided in this application embodiment, through the setting of the door frame 111 and door shell 113, combined with the design of the back panel slide groove and the clearance opening 114, ensures that the child lock structure can be locked and unlocked normally. At the same time, the overall structural design is simple, the connection method is flexible and smooth, and the user's sense of use and experience is improved.

[0082] In some embodiments, such as Figures 5-6 As shown, the locking hook 120 may include: a locking hook body 121, a locking hook pivot 151, a connecting section 125, and a first connecting part 124.

[0083] The locking hook body 121 can extend from the back plate clearance groove 115, and one end of the locking hook body 121 can be provided with a hook body 122 for locking with the main unit 160; the locking hook shaft 151 can be connected to the locking hook body 121.

[0084] It is understandable that, such as Figures 5-6 As shown, the locking hook pivot 151 and the locking hook body 121 can be integrally formed. The locking hook pivot 151 can be set at one end of the locking hook body 121, and the hook body 122 can be set at the other end of the locking hook body 121. The hook body 122 can be oriented in a direction parallel to the first frame 112.

[0085] The connecting section 125 can be connected to the other end of the locking hook body 121, and the operating part 130 can be connected to the connecting section 125.

[0086] like Figures 5-6 As shown, for the convenience of users, the operating surface of the operating unit 130 needs to be parallel to the mounting surface. Since the door 110 is placed at an angle, if the operating section is vertical, the operating surface of the operating unit 130 cannot be parallel to the mounting surface. Therefore, the operating section is set to be bent.

[0087] In this embodiment, the connecting section 125 can extend out of the clearance opening 114 of the door housing 113, and the operating part 130 can be nested on the connecting section 125 extending out of the clearance opening 114. At this time, the operating part 130 is located above the clearance opening 114. When the user moves the operating part 130, the operating part 130 can drive the locking hook 120 to rotate back and forth in the vertical direction through the connecting section 125.

[0088] The first connecting part 124 can be connected to the locking hook body 121, and the reset part 140 can be connected to the first connecting part 124.

[0089] In this embodiment, such as Figure 2 and Figures 5-6 As shown, the orientation of the first connecting part 124 can be consistent with the orientation of the hook body 122. One end of the reset member 140 can cooperate with the connecting post, and the other end of the reset member 140 can be hooked with the first connecting part 124. The reset member 140 can apply a pulling force to the locking hook 120 in the locking direction through the first connecting part 124.

[0090] The door assembly of the cooking appliance 100 provided in this application embodiment, through the setting of the aforementioned locking hook pivot 151 and the first connecting part 124, utilizes an integrated design to prevent the locking hook pivot 151 from rotating on its own, thereby enhancing the reliability of the overall design; at the same time, the reset member 140 cooperates with the first connecting part 124 to realize the elastic reset of the locking hook 120, so that the mechanical performance of the locking hook 120 will not be greatly affected during cyclic reciprocating motion, thereby increasing the stability of the entire child lock structure.

[0091] This application also discloses a cooking utensil 100.

[0092] In some embodiments, such as Figure 1 and Figure 3 As shown, the cooking appliance 100 includes: a main unit 160 and a door assembly as described above.

[0093] The main unit 160 has a cooking cavity 161.

[0094] The main unit 160 can be used to cook food through temperature control and time control. The main unit 160 may include an inner cavity and an outer cover. The inner cavity can define a cooking chamber. The cooking chamber 161 can be used as a container and cooperates with a door assembly to provide a closed environment for the food.

[0095] The door assembly door body 110 is installed on the main unit 160 in an openable and closable manner. The locking hook 120 is locked to the main unit 160 of the cooking appliance 100 in the first position and unlocked to the main unit 160 of the cooking appliance 100 in the second position.

[0096] 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 3 As shown, cooking appliance 100 is a microwave oven.

[0097] In actual operation, the user can put the food to be cooked into the cooking cavity 161. After the food is cooked, the user can operate the operating unit 130 to make the locking hook 120 rotate around the first axis from the first position until the locking hook 120 reaches the second position. At this time, the first lock of the cooking appliance 100 is released. The user can hold the handle and pull the door 110 outward with a small force. With the release of the second lock, the door 110 and the main unit 160 of the cooking appliance 100 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 and push the first frame 112 toward the main unit 160 until the locking hook 120 and the main unit 160 are locked again.

[0098] 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.

[0099] In some embodiments, such as Figure 8 and Figure 10 As shown, the front panel 162 of the main unit 160 may be provided with a locking groove 163, and the locking hook 120 may be adapted to extend into the locking groove 163 to lock with the front panel 162.

[0100] In this embodiment, such as Figure 8 and Figure 10 As shown, when the locking hook 120 is locked to the main unit 160, the hook body 122 can extend into the locking groove 163. At this time, the locking hook 120 can be in the first position, and the hook body 122 can be supported on the front panel 162. When the locking hook 120 is unlocked from the main unit 160, the hook body 122 can extend into the locking groove 163. At this time, the locking hook 120 can be in the second position, and the hook body 122 does not overlap with the front panel 162.

[0101] The cooking appliance 100 provided in this application embodiment, through the setting of the locking groove 163, eliminates the need for a connecting part that cooperates with the locking hook 120. By using the slotted front plate 162, the hook body 122 is directly supported on the edge of the locking groove 163, making the connection structure simpler and lighter, and achieving cost control without affecting the reliability of the child lock structure.

[0102] In some embodiments, such as Figure 8 and Figure 10As shown, the front panel 162 may be provided with a front panel flange 164. One end of the front panel flange 164 may be connected to one side edge of the locking groove 163, and the front panel flange 164 may overlap with the first area of ​​the front panel 162. The locking hook 120 may be directly opposite the first area in the first position, and the locking hook 120 may be adapted to lock with the front panel flange 164.

[0103] The front plate flange 164 can be formed by folding the sheet material formed during the stamping of the locking groove 163. When processing the locking groove 163, the front plate 162 can be processed by punching. After punching, a sheet material with the same cross-sectional dimensions as the locking groove 163 will be formed. The sheet material can be directly bent to form the front plate flange 164, which is simple to process. The front plate flange 164 fits the front plate 162, which can enhance the structural strength of the corresponding area.

[0104] In this embodiment, the front panel flange 164 overlaps with the first region of the front panel 162, the locking hook 120 is directly opposite the first region in the first position, and the locking hook 120 is adapted to lock with the front panel flange 164.

[0105] The hook body 122 of the locking hook 120 achieves the locking function by abutting against the front plate 162. When the locking hook 120 is in the first position, the lock body corresponds to the first area of ​​the front plate 162, that is, the lock body abuts against the first area of ​​the front plate 162. By overlapping the front plate flange 164 with the first area of ​​the front plate 162, the structural strength of the first area is enhanced and the stability of the locking structure is improved.

[0106] In some embodiments, such as Figure 1 As shown, the door assembly may have a door hook, and the front panel 162 of the main unit 160 may have a slot 165, which the door hook may engage with the slot 165.

[0107] The door hook engages with the slot 165 to achieve the second lock on the door assembly. After the control lock hook 120 is unlocked, the door body 110 needs to be pulled to separate the door hook from the slot 165 to achieve the second unlocking operation before the door assembly can be fully opened.

[0108] In actual operation, the door hook is movably mounted on the door body 110 and extends towards the front panel 162 of the main unit 160. The latch portion of the door hook can move elastically in the vertical direction, and a guide slope is provided in the slot 165. When the door assembly is closed, the end of the latch abuts against the edge of the slot 165, pushing the door hook upward and entering the slot 165 to engage and limit its movement. When opening the door assembly, the lock hook 120 is unlocked first, and then the door body 110 is pulled. The guide slope in the slot 165 applies an upward pushing force to the latch of the door hook, causing the latch to move upward and gradually disengage from the slot 165, thus realizing the door opening action.

[0109] In other embodiments, the door hook can also be a buckle fixedly installed on the door body 110, and the slot 165 is provided with a hook that can be flexibly set. Its specific structure can be referred to the common cooking utensils 100 on the market, and will not be described in detail here.
