[0056] 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.

[0057] The following is for reference. Figures 1-16 Describes a door assembly of a cooking appliance 100 according to an embodiment of this application.

[0058] like Figures 1-3 and Figures 10-12 As shown, the door assembly of the cooking appliance 100 includes a door body 110, a locking hook 120, a reset member 140, and a knob 130.

[0059] In this embodiment, the door 110 is designed to be openable and closable on the main unit 150 of the cooking appliance 100, forming a cooking cavity 151 with the main unit 150, which provides heat preservation and insulation. In some examples, the door 110 may also have a viewing window to observe the state of the food inside the main unit 150; the door 110 may also have a control panel to control the operation of the electrical appliances inside the main unit 150; and the door 110 may also have a handle for easy pulling by the user.

[0060] The locking hook 120 can be used to lock the door body 110 and the main unit 150. 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), and PC (Polycarbonate).

[0061] In this embodiment, the locking hook 120 is pivotally mounted on the first frame 114 of the door 110 between a first position and a second position about a first axis. In the first position, the locking hook 120 is adapted to lock with the main unit 150 of the cooking appliance 100, and in the second position, the locking hook 120 is adapted to unlock with the main unit 150 of the cooking appliance 100.

[0062] The locking hook 120 is pivotally mounted on the first frame 114 of the door body 110 around the first axis. The first frame 114 can be connected to the main unit 150 of the cooking appliance 100. When the locking hook 120 moves to the first position, the locking hook 120 can be locked and limited with the main unit 150 of the cooking appliance 100. At this time, the door assembly is locked and cannot be opened. When the locking hook 120 moves to the second position, the locking hook 120 is unlocked and disengaged from the main unit 150 of the cooking appliance 100. At this time, the door assembly is unlocked and can be opened.

[0063] At least a portion of the latch 120 extends from the back panel 112 of the door body 110.

[0064] The back panel 112 of the door 110 is the panel facing the main unit 150. At least a portion of the locking hook 120 extends from the back panel 112 of the door 110. The portion of the locking hook 120 extending from the back panel 112 is used to lock and limit the door against the front panel 152 of the main unit 150. The front panel 152 of the main unit 150 is used to abut against the back panel 112 of the door 110. By setting the locking hook 120 to extend from the back panel 112 of the door 110, there are no protrusions on the front or sides of the door 110, making it more aesthetically pleasing. Furthermore, when the door 110 is opened, because there are no protruding parts on the sides of the door 110, the locking hook 120 is prevented from accidentally injuring a person.

[0065] The first axis is parallel to the normal of the side of the first frame 114.

[0066] The normal to the side of the first frame 114 is a line perpendicular to that side. Since the first axis is parallel to the normal to the side of the first frame 114, the locking hook 120 rotates in a direction parallel to the side of the first frame 114.

[0067] 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.

[0068] The reset member 140 is elastically connected between the locking hook 120 and the door body 110 to apply an elastic force to the locking hook 120, keeping the locking hook 120 in the first position. When a person removes their hand from the operating section, the locking hook 120 returns to the first position under the drive of the reset member 140. When the door body 110 is closed, the locking hook 120 can lock with the main unit 150 of the cooking appliance 100, thereby fixing the door assembly.

[0069] The knob 130 is connected to the locking hook 120 and is used to drive the locking hook 120 to rotate from the first position to the second position.

[0070] The knob 130 is connected to the locking hook 120. The rotation axis of the knob 130 can coincide with the first axis. When the knob 130 is rotated, the locking hook 120 rotates synchronously with the knob 130. The locking hook 120 can be driven to rotate from the first position to the second position by manually operating the knob 130.

[0071] It should be noted that the locking hook 120 of this application can be a safety lock for the cooking appliance 100. That is, the locking hook 120 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 door handle outward with a small force.

[0072] In actual implementation, such as Figure 6 , Figure 7 and Figure 15 As shown, the locking hook 120 is held in the first position by the force of the reset member 140, and the locking hook 120 is locked with the main unit 150, preventing the door assembly from opening. To open the door, the knob 130 must be manually rotated first to drive the locking hook 120 to the second position, thus unlocking the locking hook 120 from the main unit 150. Figure 8 , Figure 9 and Figure 16 As shown, after completing the first unlocking step, pull the door assembly to separate it from the main unit 150 to achieve the second unlocking step. After unlocking twice, the door assembly completes the opening action. When closing the door, simply close the door assembly onto the main unit 150. The lock hook 120 returns to the first position under the action of the reset member 140 and locks with the main unit 150, preventing the door assembly from opening and completing the closing of the door assembly.

[0073] According to the door assembly provided in the embodiments of this application, a locking hook 120 and a reset member 140 are provided so that the door assembly can be locked to the main unit 150 of the cooking appliance 100 through the locking hook 120. When opening the door, the operating segment must first be controlled to drive the locking hook 120 to unlock, and then the door assembly must be pulled to separate it from the main unit 150. The door assembly can be opened by two operations, which can prevent children from accidentally opening the door assembly, reduce the risk of children being burned by hot food inside the cooking appliance 100 or putting dangerous items into the cooking appliance 100, and the opening and closing operation is simple.

[0074] like Figure 2 and Figure 11 As shown, according to some embodiments of this application, the first frame 114 is a frame opposite to the pivot axis of the door body 110.

[0075] One frame of the door 110 is pivotally connected to the host 150. The pivot axis is the axis on which the door 110 rotates relative to the host 150. The connection between the door 110 and the host 150 can be a pin 123 connection. The first frame 114 is the frame opposite to the frame where the pivot axis of the door 110 is located. By installing the locking hook 120 on the first frame 114, the two fixed positions of the door 110 and the host 150 are arranged on the two opposite frames of the door 110, making the connection between the door 110 and the host 150 more stable.

[0076] In this embodiment, the door handle can be positioned close to the first frame 114, based on the position where the human body can most easily exert force to open the door.

[0077] like Figure 2 and Figure 11 As shown, according to some embodiments of this application, the pivot axis of the door 110 can be located at the lower edge of the door 110, and the first edge 114 can be the upper edge of the door 110.

[0078] The pivot axis of the door body 110 is located on the lower frame of the door body 110, so that the door body 110 is set as a downward opening door. The first frame 114 is the upper frame of the door body 110, and the lock hook 120 is correspondingly set on the upper frame. Correspondingly, the slider is also located on the upper frame for easy manual operation.

[0079] In this embodiment, because the first frame 114 is arranged horizontally, the first axis is arranged vertically, and the locking hook 120 is pivotally mounted on the first frame 114 about vertically.

[0080] By setting the door 110 to open downwards, it is easier to pull it down according to human operating habits, and the door 110 can be used to hold food after it is opened, which can prevent food from falling when it is very hot.

[0081] In some embodiments, the pivot axis of the door body 110 may also be located on the left or right side frame of the door body 110, so that the door body 110 is configured as a side-opening door. The first frame 114 is the right or left frame opposite to the pivot axis of the door body 110. In this case, the lock hook 120 is installed on the first frame 114 by rotating laterally.

[0082] like Figure 5 and Figure 14 As shown, according to some embodiments of this application, the locking hook 120 may include a connecting arm 121 and a hook body 122.

[0083] like Figure 2 , Figure 3 , Figure 11 and Figure 12As shown, the connecting arm 121 passes through the door body 110, the first axis passes through the connecting arm 121, and the knob 130 is connected to the connecting arm 121.

[0084] The connecting arm 121 can extend along the width direction of the first frame 114 to penetrate the back panel 112 of the door body 110. The first axis passes through the connecting arm 121, and the connecting arm 121 is pivotally mounted about the first axis. The locking and unlocking of the lock hook 120 is achieved by rotating the connecting arm 121. The reset member 140 is connected to the connecting arm 121 and is used to drive the connecting arm 121 to reset and hold it in the first position.

[0085] The hook 122 can be connected to the connecting arm 121 and can be spaced apart from the first axis.

[0086] Hook 122 is connected to connecting arm 121. Hook 122 can be hook-shaped, extending to one side from connecting arm 121. Hook 122 can engage with main unit 150 for locking. Hook 122 is spaced apart from the first axis so that hook 122 has an arc-shaped movement stroke when connecting arm 121 rotates around the first axis. It is understood that the greater the distance between hook 122 and the first axis, the greater the movement stroke of hook 122. In this embodiment, hook 122 can be connected to the end of connecting arm 121 closest to main unit 150. By rotating connecting arm 121, hook 122 is moved, causing hook 122 to hook onto front plate 152 of main unit 150 for locking, or hook 122 to separate from front plate 152 of main unit 150 for unlocking.

[0087] It should be noted that the hook body 122 can be integrated with the connecting arm 121.

[0088] In some embodiments, such as Figure 3 , Figure 6 and Figure 8 As shown, the connecting arm 121 may have a first connecting portion, and one end of the reset member 140 may be connected to the first connecting portion to drive the connecting arm 121 to reset. The first connecting portion may be a connecting hole, and the reset member 140 may be a torsion spring. The torsion spring has two support legs, which are respectively connected to the door body 110 and the connecting hole. By compressing the torsion spring, the torsion spring always applies a reset force to the connecting arm 121 to rotate from the second position to the first position.

[0089] In other embodiments, such as Figure 12 , Figure 14 and Figure 15As shown, a connecting plate 126 may be provided on one side of the connecting arm 121. A first connecting part may be provided on the connecting plate 126. One end of the reset member 140 may be connected to the first connecting part to drive the connecting arm 121 to reset. The first connecting part may be a connecting hole, and the reset member 140 may be a tension spring. One end of the tension spring is fixedly connected to the door body, and the other end of the tension spring may be connected to the first connecting part on the connecting plate 126. By stretching the tension spring, the tension spring always applies a reset force to the connecting arm 121 to rotate from the second position to the first position.

[0090] It should be noted that the connecting hole is not intersecting with the first axis. The axis of the connecting hole and the first axis can be parallel or not parallel.

[0091] In other embodiments, the reset member 140 may also be a tension spring or a compression spring, with one end of the reset member 140 connected to the host and the other end connected to the first connecting part of the connecting arm 121. In this case, the first connecting part may be a connecting shaft or a protrusion, and a reset force is applied to the connecting arm 121 to rotate from the second position to the first position by means of the tension spring or the compression spring.

[0092] like Figure 5 and Figure 14 As shown, according to some embodiments of this application, the locking hook 120 may also include a pin 123.

[0093] The pin 123 can be connected to the connecting arm 121, and the axis of the pin 123 coincides with the first axis. The knob 130 can be connected to the pin 123.

[0094] The axis of the pin 123 coincides with the first axis. By connecting the knob 130 to the pin 123, the knob 130 drives the pin 123 to rotate, which in turn drives the connecting arm 121 to rotate. The pin 123 and the hook 122 are located on adjacent sides of the connecting arm 121, so that when the connecting arm 121 rotates with the pin 123, the hook 122 can engage and limit the movement of the main body.

[0095] In some embodiments, such as Figure 4 and Figure 5 As shown, the knob 130 has a connecting groove 131, and the pin 123 includes a second connecting part 124. The second connecting part 124 is a non-rotating body and is connected to the connecting groove 131. The connecting groove 131 has a non-rotating cross-section; for example, it can be polygonal, or it can include arc-shaped or planar sidewalls. The cross-section of the second connecting part 124 is adapted to the cross-section of the connecting groove 131 so that no relative rotation occurs when the connecting groove 131 and the second connecting part 124 are engaged.

[0096] According to some embodiments of this application, such as Figure 12 and Figure 13 As shown, the knob 130 may include a sleeve 132 and a handle 133. The sleeve 132 may be fitted over the pin 123, and the handle 133 may be connected to the sleeve 132 and extend in a direction away from the first axis.

[0097] The sleeve 132 can be sleeved over the pin 123, and a connecting groove 131 can be formed inside the sleeve 132. The connecting groove 131 is used to connect with the connecting part 124 on the pin 123. The specific arrangement of the connecting groove 131 and the second connecting part 124 can be referred to the aforementioned embodiment, and will not be repeated here. By rotating the sleeve 132, the second connecting part 124 is driven to drive the connecting arm 121 to rotate.

[0098] The handle 133 is connected to the sleeve 132. The handle 133 is located outside the sleeve 132 and extends in a direction away from the first axis. The handle 133 is fixedly connected to the sleeve 132. The user can rotate the sleeve 132 by turning the handle 133, making the rotation of the knob 130 easier and more convenient for the user to operate.

[0099] According to some embodiments of this application, one of the connecting arm 121 and the door body 110 may be provided with a lock hook pivot 125, and the other may be provided with a shaft hole that pivotally engages with the lock hook pivot 125.

[0100] By providing a locking hook pivot 125 and a shaft hole that mates with the locking hook pivot 125, the connecting arm 121 can rotate relative to the door body 110. It is understood that the axes of the locking hook pivot 125 and the shaft hole coincide with the first axis.

[0101] In one example, such as Figure 5 and Figure 14 As shown, the door body 110 is provided with a shaft hole, and the connecting arm 121 is provided with a lock hook rotating shaft 125 that cooperates with the shaft hole.

[0102] In another example, the door body 110 is provided with a lock hook pivot 125, and the connecting arm 121 is provided with a shaft hole that mates with the lock hook pivot 125.

[0103] In this embodiment, the lock hook pivot 125 or the pivot hole and the pin 123 are located on opposite sides of the connecting arm 121 to facilitate the connection between the connecting arm 121 and the door body 110, and the connection between the connecting arm 121 and the knob 130.

[0104] like Figure 2 , Figures 6-9 , Figure 11 , Figure 15 and Figure 16As shown, according to some embodiments of this application, the back plate 112 of the first frame 114 may be provided with a back plate clearance groove 113, the connecting arm 121 passes through the back plate clearance groove 113, and the hook 122 extends out from the door body 110.

[0105] The back plate 112 of the first frame 114 is provided with a back plate clearance groove 113 for the connecting arm 121 to pass through. The back plate 112 of the first frame 114 is used to abut against the front plate 152 of the host 150. The hook 122 extends out from the door body 110 through the back plate clearance groove 113 to cooperate with the front plate 152 of the host 150 to lock and realize the locking and fixing of the door assembly.

[0106] It is understood that the size of the back plate clearance groove 113 is not less than the range of motion of the locking hook 120 between the first position and the second position, so as to ensure that the locking hook 120 can move to the first position and the second position within the back plate clearance groove 113.

[0107] In this embodiment, the first axis extends vertically, and the end of the locking hook 120 is rotatably arranged horizontally. Therefore, the distance between the two side walls of the back plate clearance groove 113 in the horizontal direction is not less than the maximum space occupied by the locking hook 120 in the first and second positions. That is, in the first position, the locking hook 120 can abut against or be spaced apart from one side wall of the clearance groove in the horizontal direction, and in the second position, the locking hook 120 can abut against or be spaced apart from the other side wall of the clearance groove in the horizontal direction.

[0108] According to some embodiments of this application, such as Figure 2 and Figure 11 As shown, the door body 110 includes a door frame 111 and a door shell 115.

[0109] The door frame 111 is pivotally connected to the host 150. The door frame 111 has multiple side frames, and the back plates 112 of the multiple side frames are interconnected to form the back plate 112 of the door frame 111. The back plate 112 of the door frame 111 is provided with a back plate clearance groove 113. The multiple side frames include a first side frame 114. The back plate clearance groove 113 is correspondingly provided on the back plate 112 of the first side frame 114. At least a portion of the lock hook 120 extends from the back plate clearance groove 113 to lock and limit the position with the host 150.

[0110] In this embodiment, the door housing 115 can be installed on the outside of the door frame 111, and the door housing 115 can have a clearance opening 116 through which the lock hook 120 or the knob 130 passes.

[0111] The door housing 115 is installed on the outside of the door frame 111. The door frame 111 is used to support the door housing 115, and the door housing 115 is used to protect the door frame 111. The periphery flange of the door housing 115 is connected to the periphery of the back plate 112 of the door frame 111 so as to cover the frame inside the door housing 115.

[0112] The door housing 115 is provided with a clearance opening 116, through which a lock hook 120 or a knob 130 passes, so that there is an operable part on the outside of the door housing 115 that can be operated by a person. The following explains this embodiment from two possible perspectives.

[0113] 1. Locking hook 120 penetrates through clearance opening 116:

[0114] A pin 123 may be provided on the lock hook 120. The axis of the pin 123 coincides with the first axis. The pin 123 extends outward through the clearance opening 116. A knob 130 is located outside the door housing 115 for manual operation. The pin 123 of the lock hook 120 is connected to the connecting groove 131 on the knob 130, so that the lock hook 120 can be rotated when the knob 130 is turned. The cross-sectional dimension of the knob 130 can be larger than the cross-sectional dimension of the clearance opening 116. The knob 130 covers the clearance opening 116 to prevent dust from entering the door housing 115 through the clearance opening 116.

[0115] II. Knob 130 penetrates through clearance opening 116:

[0116] The knob 130 can pass through the clearance opening 116 from the outside to the inside to connect with the lock hook 120. At least part of the knob 130 is located outside the door housing 115 for manual operation. The knob 130 can be fixed to the lock hook 120 through a pin hole, threaded connection, or adhesive connection, etc., and the connection method is not limited here. By inserting the knob 130 into the clearance opening 116, the installation of the knob 130 is more stable and less likely to fall off.

[0117] This application also discloses a cooking utensil 100.

[0118] In some embodiments, such as Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, the cooking appliance 100 includes a main unit 150 and a door assembly as described above.

[0119] The main unit 150 has a cooking cavity 151.

[0120] The main unit 150 can be used to cook food through temperature control and time control, and the cooking cavity 151 can be used as a container to provide a closed environment for food in conjunction with the door assembly.

[0121] The door assembly door body 110 is closably mounted on the main unit 150. The locking hook 120 is locked to the main unit 150 of the cooking appliance 100 in the first position and unlocked to the main unit 150 of the cooking appliance 100 in the second position.

[0122] 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 , Figure 2 , Figure 10 and Figure 11 As shown, cooking appliance 100 is a microwave oven.

[0123] In actual operation, the user can place the food to be cooked into the cooking cavity 151. After the food is cooked, the user can turn the knob 130 to make the locking hook 120 rotate 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. At the same time, the user can hold the door 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 150 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 door handle and push the first frame 114 toward the main unit 150 until the locking hook 120 and the main unit 150 lock again.

[0124] 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.

[0125] In some embodiments, such as Figures 6-9 , Figure 15 and Figure 16 As shown, the front panel 152 of the main unit 150 may be provided with a locking groove 153, and the locking hook 120 may be adapted to extend into the locking groove 153 to lock with the front panel 152.

[0126] In this embodiment, such as Figures 6-9 , Figure 15 and Figure 16 As shown, the cross-sectional dimension of the locking groove 153 can be slightly larger than the distance between the first position and the second position. When the locking hook 120 is locked with the main unit 150, the hook body 122 extends into the locking groove 153. At this time, the locking hook 120 is in the first position, and the hook body 122 can abut against the front plate 152. When the locking hook 120 is unlocked from the main unit 150, the hook body 122 extends into the locking groove 153. The locking hook 120 body 122 is in the second position, and the hook body 122 does not overlap with the front plate 152.

[0127] The cooking appliance 100 provided in this application embodiment, through the setting of the locking groove 153, eliminates the need for a connecting part that cooperates with the locking hook 120. By using the slotted front plate 152, the hook body 122 is directly supported on the edge of the locking groove 153, making the connection structure simpler and lighter, and achieving cost control without affecting the reliability of the child lock structure.

[0128] According to some embodiments of this application, such as Figure 7 and Figure 9 As shown, the front panel 152 may be provided with a front panel flange 154, and one end of the front panel flange 154 may be connected to one side edge of the locking groove 153.

[0129] The front plate flange 154 can be formed by folding the sheet material formed during the stamping of the locking groove 153. When processing the locking groove 153, the front plate 152 can be processed by punching. After punching, a sheet material with the same cross-sectional dimensions as the locking groove 153 will be formed. The sheet material can be directly bent to form the front plate flange 154, which is simple to process. The front plate flange 154 fits the front plate 152, which can enhance the structural strength of the corresponding area.

[0130] In this embodiment, such as Figure 6 , Figure 7 and Figure 15 As shown, the front panel flange 154 overlaps with the first area of ​​the front panel 152, the locking hook 120 is directly opposite the first area in the first position, and the locking hook 120 is adapted to lock with the front panel flange 154.

[0131] The hook body 122 of the locking hook 120 achieves the locking function by abutting against the front plate 152. When the locking hook 120 is in the first position, the locking body corresponds to the first area of ​​the front plate 152, that is, the locking body abuts against the first area of ​​the front plate 152. By overlapping the front plate flange 154 with the first area of ​​the front plate 152, the structural strength of the first area is enhanced and the stability of the locking structure is improved.

[0132] According to some embodiments of this application, the door assembly may have a door hook, and the front panel 152 of the host 150 may have a slot 155 for engaging with the slot 155.

[0133] The door assembly is also equipped with a door hook, and the front plate 152 of the main unit 150 has a slot 155. The door hook and the slot 155 engage to realize the second lock of 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 155 to realize the second unlocking operation before the door assembly can be fully opened.

[0134] In some embodiments, the door hook is movably mounted on the door body 110 and extends toward the front plate 152 of the host 150. The latch portion of the door hook is elastically movable in the vertical direction, and a guide slope is provided in the slot 155. When the door assembly is closed, the end of the latch abuts against the edge of the slot 155, pushing the door hook upward and entering the slot 155 to engage and limit its movement. When opening the door assembly, the lock hook 120 is first unlocked, and then the door body 110 is pulled. The guide slope in the slot 155 applies an upward pushing force to the latch of the door hook, causing the latch to move upward and gradually disengage from the slot 155, thus realizing the door opening action.

[0135] In other embodiments, the door hook can also be a buckle fixedly installed on the door body 110, and the slot 155 is provided with a hook that can be flexibly set. Its specific structure can be referred to common cooking utensils on the market, and will not be described in detail here.
