DETAILED DESCRIPTION

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0027] Refer to the following Figures 1 to 4 The lock structure 100 and the cooking appliance provided according to some embodiments of the present invention are described.

[0028] Combination Figure 1 , Figure 2 and Figure 3As shown, in an embodiment of the present invention, a lock structure 100 is proposed. The lock structure 100 is used for a cooking utensil. The cooking utensil includes a cavity assembly 200 and a door assembly 300 connected to each other. The lock structure 100 includes: a mounting member 110, a locking member 120 and a limiting member 130. The mounting member 110 is used to be connected to one of the door assembly 300 and the cavity assembly 200. The other of the door assembly 300 or the cavity assembly 200 is provided with a connecting portion 310. The locking member 120 is connected to the mounting member 110. The locking member 120 can move between a locked position and an unlocked position. In the locked position, the locking member 120 is used to be connected to the connecting portion 310. In the unlocked position, the locking member 120 is separated from the connecting portion 310. The limiting member 130 is connected to the mounting member 110 , the locking member 120 is located in the locking position, and the limiting member 130 operates in the first state, the limiting member 130 is used to limit the locking member 120 , and the limiting member 130 operates in the second state, the limiting member 130 releases the limit on the locking member 120 .

[0029] The lock structure 100 provided in this embodiment is used for a cooking utensil, which includes a door assembly 300 and a cavity assembly 200. The mounting member 110, the locking member 120 and the limiting member 130 serve as a child lock, which plays a role in assisting the connection between the door assembly 300 and the cavity assembly 200. By adding the lock structure 100 to one of the door assembly 300 or the cavity assembly 200, when the door assembly 300 closes the cavity assembly 200, the lock structure 100 restricts the door assembly 300 from opening the cavity assembly 200, thereby realizing the function of the child lock.

[0030] In this embodiment, the lock structure 100 is disposed on the cavity assembly 200 for exemplary description.

[0031] When opening and closing the door, the user can control the limiter 130 to lock and unlock the cooking utensil. Specifically, when the door assembly 300 closes the cavity assembly 200, the locking member 120 is located in the locking position, and the locking member 120 is connected to the connecting portion 310 in the door assembly 300. At this time, the user can control the limiter 130 to switch to the first state, and the limiter 130 operating in the first state limits the locking member 120. At this time, the locking member 120 cannot move relative to the door assembly 300. Before opening the cavity assembly 200, the limiter 130 needs to be switched to the second state, and the limiter 130 in the second state is separated from the operating member locking member 120. At this time, the limiter 130 no longer limits the locking member 120, and the user can open the cavity assembly 200 by pulling the door assembly 300. Opening the cavity assembly 200 requires two steps, which is conducive to improving the safety of the cooking utensil.

[0032] In the present invention, a child lock structure is added to the cooking utensil. When the locking member 120 moves to the first position, the limiting member 130 limits the movement of the locking member 120. The locking member 120 limits the door body assembly 300, and the door body assembly 300 is difficult to open the cavity assembly 200, thereby keeping the door body in a locked state, and therefore the cavity assembly 200 cannot be opened.

[0033] In order to open the cavity assembly 200, it is necessary to release the position limit of the locking member 120 on the door assembly 300, so it is necessary to first release the position limit of the locking member 120 by the limiting member 130. When the limiting member 130 and the locking member 120 are separated, the locking member 120 can move relative to the mounting member 110, so that the position limit of the locking member 120 on the door assembly 300 can be released. Therefore, when opening the door, the user needs to first switch the limiting member 130 to the second state, which is the first step, and then pull the door assembly 300 to open the cavity assembly 200, which is the second step. The two-step operation increases the difficulty of opening the door.

[0034] After the cooking process of the cooking appliance is finished, the temperature of the food in the cooking cavity is high. At this time, if the user directly opens the door to take out the food, there is a risk of scalding. Therefore, the present invention uses the above-mentioned lock structure 100 so that if the user wants to open the cavity assembly 200, he must perform a two-step door opening operation before opening the cavity assembly 200. In this way, on the one hand, it can serve as a certain reminder to the user, and on the other hand, it can prevent children from accidentally opening the cavity assembly 200, thereby greatly improving the safety of the cooking appliance.

[0035] The locking member 120 and the limiting member 130 are mounted on the mounting member 110 , so the lock structure 100 is an integral structure, which facilitates the assembly of the lock structure 100 .

[0036] It should be noted that the first state and the second state refer to the operating states of the limiting member 130 .

[0037] like Figure 2 As shown, in some embodiments, optionally, a plug-in portion 121 is provided on the locking member 120, and the locking member 120 is rotatably connected to the mounting member 110. When in the locked position, the plug-in portion 121 is used to engage with the connecting portion 310. The plug-in portion 121 can rotate under the pulling of the connecting portion 310 to rotate the locking member 120 to the unlocking position.

[0038] The locking member 120 can rotate between a locked position and an unlocked position relative to the mounting member 110. When the limiting member 130 is in the first state, the limiting member 130 limits the locking member 120. At this time, the locking member 120 cannot rotate relative to the mounting member 110, so that the locking member 120 can limit the door assembly 300. When the limiting member 130 is in the second state, the limiting member 130 releases the limit on the locking member 120. At this time, the locking member 120 can rotate relative to the mounting member 110, so that the locking member 120 releases the limit on the door assembly 300.

[0039] In the following embodiments, the connection portion 310 is provided on the door assembly 300 for exemplary description, and the connection portion 310 is provided on the cavity assembly 200 in the same principle.

[0040] When the door assembly 300 closes the cavity assembly 200, the locking member 120 is connected to the connecting portion 310. When the limiting member 130 limits the locking member 120, the locking member 120 cannot rotate relative to the mounting member 110, so the locking member 120 and the connecting portion 310 are not easy to separate. At this time, even if the door assembly 300 is pulled, it is difficult to open the cavity assembly 200. When the limiting member 130 releases the limit on the locking member 120, the locking member 120 can rotate freely. When the user pulls the door assembly 300, the connecting portion 310 can pull the plug-in portion 121, so that the locking member 120 can rotate under the pull of the connecting portion 310. As the locking member 120 rotates, the plug-in portion 121 gradually separates from the connecting portion 310, and the plug-in portion 121 does not limit the connecting portion 310, so that the cavity assembly 200 can be opened smoothly.

[0041] like Figure 2 As shown, in some embodiments, optionally, a portion to be pushed 122 is provided on the locking member 120, and the portion to be pushed 122 is used to be pushed by the connecting portion 310 to rotate the locking member 120 to the locking position.

[0042] During the door opening process, the plug-in portion 121 is pulled by the connecting portion 310 and rotates, so that the locking member 120 can be rotated to the unlocked position. When the door is closed, in order to enable the locking member 120 to limit the connecting portion 310, it is necessary to ensure that the locking member 120 is in the locked position. The rotation of the locking member 120 from the unlocked position to the locked position is driven by the connecting portion 310.

[0043] Specifically, a portion to be pushed 122 is provided on the locking member 120. During the door closing process, the connecting portion 310 contacts the portion to be pushed 122. As the connecting portion 310 moves, the portion to be pushed 122 is pushed by the connecting portion 310. Therefore, as the connecting portion 310 moves, the locking member 120 rotates from the unlocking position to the locking position. When the door body assembly 300 closes the cavity assembly 200, the locking member 120 just rotates to the locking position. At this time, the plug-in portion 121 is engaged with the connecting portion 310.

[0044] The pushing portion 122 is pushed by the connecting portion 310, so that the door body assembly 300 and the locking member 120 are linked. During the door closing process, the locking member 120 can be pushed and rotated to the locking position. There is no need to set up an electric drive structure to drive the locking member 120, which is beneficial to simplify the structure of the cooking appliance.

[0045] In one possible application, a socket 311 is provided on the connecting portion 310, and the plug-in portion 121 can be plugged into the socket 311. During the door opening process, the plug-in portion 121 gradually rotates out of the socket 311. During the door closing process, the movement of the connecting portion 310 and the rotation of the locking member 120 are synchronized, so that the plug-in portion 121 is gradually inserted into the socket 311.

[0046] In other embodiments, the lock structure 100 further includes a motor, and the locking member 120 is connected to the motor, and the motor is used to drive the locking member 120 to rotate between the locking position and the unlocking position.

[0047] Combination Figure 2 and Figure 4 As shown, in some embodiments, optionally, a limiting surface 123 is provided on the first side of the plug-in portion 121, and an inclined surface 124 is provided on the second side of the plug-in portion 121, and the limiting surface 123 is used to limit the connecting portion 310, and the first end of the plug-in portion 121 is away from the rotation center of the locking member 120, and the distance between the limiting surface 123 and the inclined surface 124 increases from the first end of the plug-in portion 121 to the second end of the plug-in portion 121.

[0048] A limiting surface 123 and an inclined surface 124 are respectively provided on two opposite sides of the plug-in part 121. When the plug-in part 121 is engaged with the connecting part 310, the limiting surface 123 limits the connecting part 310, so that the connecting part 310 is not easily separated from the plug-in part 121, thereby ensuring that the cavity assembly 200 is in a locked state.

[0049] From the first end of the plug-in portion 121 to the second end of the plug-in portion 121, the distance between the limiting surface 123 and the inclined surface 124 increases. When the connecting portion 310 pulls the plug-in portion 121, the distance between the inclined surface 124 and the connecting portion 310 remains substantially unchanged, thereby ensuring that a certain gap is maintained between the inclined surface 124 and the connecting portion 310, avoiding contact between the inclined surface 124 and the connecting portion 310, thereby preventing the rotation of the plug-in portion 121 and the movement of the connecting portion 310 from interfering, and ensuring the matching stability of the door body assembly 300 and the lock structure 100.

[0050] Combination Figure 2 and Figure 4 As shown, in some embodiments, optionally, the lock structure 100 further includes a rotating shaft 140 and a boss 150, the rotating shaft 140 is connected to the mounting member 110, the locking member 120 is provided with an axial hole 125, and the rotating shaft 140 passes through the shaft. The boss 150 is connected to the rotating shaft 140, the locking member 120 is located between the boss 150 and the mounting member 110, and the locking member 120 is provided with a limiting groove 126, which is connected to the axial hole 125. When the boss 150 is misaligned with the limiting groove 126, the boss 150 is used to limit the locking member 120 from being separated from the rotating shaft 140, and when the boss 150 is opposite to the limiting groove 126, the boss 150 can pass through the limiting groove 126.

[0051] A rotating shaft 140 is provided on the mounting member 110 , and the rotating shaft 140 and the mounting member 110 may be an integrally formed structure. An axial hole 125 is machined and formed on the locking member 120 , and the rotating shaft 140 passes through the axial hole 125 , so that the locking member 120 can rotate around the rotating shaft 140 .

[0052] A boss 150 is provided on the side of the rotating shaft 140, and the boss 150 and the rotating shaft 140 may be an integrally formed structure. Specifically, a portion of the rotating shaft 140 passes through the shaft hole 125, and the boss 150 is provided on a portion of the rotating shaft 140 that passes through the shaft hole 125, so that the locking member 120 is located between the boss 150 and the mounting member 110, and the boss 150 can limit the locking member 120 to prevent the locking member 120 from being separated from the rotating shaft 140, thereby ensuring the connection stability between the locking member 120 and the rotating shaft 140.

[0053] The locking member 120 is also provided with a limiting groove 126, which is connected to the shaft hole 125. When the boss 150 and the limiting groove 126 are misaligned, the boss 150 limits the locking member 120. When the boss 150 and the limiting groove 126 are opposite to each other, the locking member 120 can be pulled along the axial direction of the rotating shaft 140, and the boss 150 can pass through the limiting groove 126, so that the locking member 120 can be disassembled, and the installation method of the locking member 120 is similar.

[0054] The boss 150 and the limiting groove 126 cooperate with each other, which helps to improve the convenience of disassembly and assembly of the locking member 120.

[0055] Combination Figure 2 and Figure 4 As shown, in some embodiments, optionally, a slot 127 is provided on one of the locking member 120 and the limiting member 130, the locking member 120 is located in the locking position, and the limiting member 130 operates in the first state, and the other of the locking member 120 and the limiting member 130 is inserted into the slot 127.

[0056] When the limiting member 130 limits the locking member 120, the limiting member 130 and the locking member 120 are in a plug-in fitting relationship. For example, a slot 127 is provided on the locking member 120, and the limiting member 130 is plugged into the slot 127, thereby limiting the locking member 120. Alternatively, a slot 127 is provided on the limiting member 130, and the locking member 120 is inserted into the slot 127, thereby limiting the locking member 120.

[0057] In this embodiment, the slot 127 is arranged on the locking member 120. When the locking member 120 is in the locking position, the slot 127 is opposite to the limiting member 130. The limiting member 130 operates in the first state, so that a part of the limiting member 130 is inserted into the slot 127, and the limiting member 130 limits the rotation of the locking member 120.

[0058] Combination Figure 2 and Figure 4 As shown, in some embodiments, optionally, the limiting member 130 includes: a solenoid valve body 131 and an output shaft 132, the solenoid valve body 131 is connected to the mounting member 110, the output shaft 132 is connected to the solenoid valve body 131, in the first state of the solenoid valve body 131, the output shaft 132 moves to a first position relative to the solenoid valve body 131, the output shaft 132 limits the locking member 120, in the second state, the output shaft 132 moves to a second position, and the output shaft 132 is separated from the locking member 120.

[0059] The position-limiting member 130 in this embodiment is a solenoid valve. When the solenoid valve is powered on, the output shaft 132 extends out of the solenoid valve body 131. When the solenoid valve is powered off, at least a portion of the output shaft 132 is retracted into the solenoid valve body 131. In this embodiment, the solenoid valve being in the first state means that the solenoid valve is powered on, and the solenoid valve being in the second state means that the solenoid valve is powered off.

[0060] When the locking member 120 rotates to the locking position, the solenoid valve is energized, and the solenoid valve body 131 drives the output shaft 132 to move, so that the output shaft 132 moves to a position to limit the locking member 120. For example, the output shaft 132 is inserted into the slot 127 on the locking member 120. Since the solenoid valve is fixed on the mounting member 110, the position of the solenoid valve is not easy to change, so that the output shaft 132 limits the rotation of the locking member 120.

[0061] When the door needs to be opened, the user can control the solenoid valve to cut off the power, the output shaft 132 is separated from the locking member 120, and the locking member 120 can rotate freely.

[0062] In a possible application, the axial direction of the output shaft 132 extends in the direction of the plumb bob. When the solenoid valve is powered off, the output shaft 132 falls freely due to its own gravity, and the output shaft 132 is gradually retracted into the solenoid valve body 131 .

[0063] In a possible application, an unlock button may be provided on the cooking appliance, and the unlock button may be a physical button or a virtual button. When the user presses the unlock button, the solenoid valve is powered on or off. Alternatively, the user may control the power on and off of the solenoid valve through an APP.

[0064] Combination Figure 2 and Figure 4 As shown, in some embodiments, optionally, the limiting member 130 further includes: a guide member 133 , the guide member 133 is connected to the mounting member 110 , a guide hole 134 is provided on the guide member 133 , and the output shaft 132 passes through the guide hole 134 .

[0065] The guide member 133 is installed on the mounting member 110 . For example, the guide member 133 is locked to the mounting member 110 by a locking member such as a screw, so that the guide member 133 is not easy to move relative to the mounting member 110 .

[0066] A guide hole 134 is provided on the guide member 133, and the output shaft 132 passes through the guide hole 134, and the output shaft 132 can slide in the guide hole 134. The guide hole 134 limits the output shaft 132. When the output shaft 132 limits the locking member 120, if the door assembly 300 is pulled at this time, the connecting portion 310 will generate a pulling force on the locking member 120, and the locking member 120 has a tendency to rotate. At this time, the output shaft 132 will be pushed by the locking member 120. The output shaft 132 is limited by the guide hole 134, and the output shaft 132 is not easy to deform, which is conducive to improving the limiting stability of the output shaft 132 on the locking member 120.

[0067] The guide hole 134 can also guide the output shaft 132 , thereby ensuring that the output shaft 132 can stably cooperate with the locking member 120 , thereby improving the cooperation stability between the output shaft 132 and the locking member 120 .

[0068] Combination Figure 2 and Figure 4 As shown, in some embodiments, optionally, the output shaft 132 includes a shaft body 135, a first limiting portion 136 and a second limiting portion 137, the shaft body 135 is connected to the solenoid valve body 131, the first limiting portion 136 is connected to the shaft body 135, the first limiting portion 136 passes through the guide hole 134, and is used to limit the locking member 120. The second limiting portion 137 is connected to the first limiting portion 136, and when the output shaft 132 is located at the first position, the second limiting portion 137 contacts the side of the guide member 133 that is away from the locking member 120.

[0069] The shaft body 135 is connected to the solenoid valve body 131, and the solenoid valve body 131 is used to drive the shaft body 135 to move. The first limiter 136 is connected to the shaft body 135, and the first limiter 136 can pass through the guide hole 134 and can slide in the guide hole 134. The second limiter 137 is connected to the first limiter 136, and along the radial direction of the output shaft 132, the cross-sectional area of ​​the second limiter 137 is larger than the cross-sectional area of ​​the first limiter 136, and the first limiter 136 can pass through the guide hole 134, while the second limiter 137 cannot extend into the guide hole 134. When the shaft body 135 limits the locking member 120, the second limiter 137 contacts the side of the guide member 133 that is away from the locking member 120. The second limiter 137 is used to limit the movement stroke of the shaft body 135 to prevent the first limiter 136 from excessively moving and causing damage to the locking member 120.

[0070] In a possible application, the first limiting portion 136 is locked to the shaft body 135 by a locking member such as a screw, and the second limiting portion 137 and the first limiting portion 136 are an integrally formed structure.

[0071] Combination Figure 2 and Figure 4 As shown, in some embodiments, optionally, the limit member 130 also includes: an elastic member 138, the elastic member 138 is connected to the output shaft 132 and the solenoid valve body 131, when the output shaft 132 is in the first position, the elastic member 138 is in an elastic deformation state, when the output shaft 132 is in the second position, the elastic member 138 is in an original state.

[0072] The elastic member 138 is located between the output shaft 132 and the solenoid valve body 131 . When the output shaft 132 moves relative to the solenoid valve body 131 , the output shaft 132 drives the elastic member 138 to undergo elastic deformation. When the solenoid valve is powered off, the elastic member 138 drives the output shaft 132 to move and reset.

[0073] Specifically, the elastic member 138 is sleeved on the output shaft 132, and the two ends of the elastic member 138 are respectively connected to the output shaft 132 and the solenoid valve body 131. When the output shaft 132 moves relative to the solenoid valve body 131, the output shaft 132 drives the first end of the elastic member 138 to move, so that the elastic member 138 is compressed. When the solenoid valve is powered off, the output shaft 132 falls freely under the action of gravity. At this time, the elastic member 138 also provides a reset thrust for the output shaft 132, which can effectively avoid the situation where the output shaft 132 is not reset due to jamming, which is beneficial to improving the working stability of the solenoid valve.

[0074] Combination Figure 1 , Figure 2 and Figure 3 As shown, in an embodiment of the present invention, a cooking utensil is proposed, comprising: a cavity assembly 200, a door assembly 300 and a lock structure 100 in any of the above embodiments, the door assembly 300 is connected to the cavity assembly 200 in an opening and closing manner, the mounting member 110 is provided on one of the cavity assembly 200 and the door assembly 300, and a connecting portion 310 is provided on the other of the cavity assembly 200 and the door assembly 300. By adding the lock structure 100 to one of the door assembly 300 or the cavity assembly 200, when the door assembly 300 closes the cavity assembly 200, the lock structure 100 restricts the door assembly 300 from opening the cavity assembly 200, thereby realizing the function of a child lock.

[0075] In this embodiment, the lock structure 100 is disposed on the cavity assembly 200 for exemplary description.

[0076] When opening and closing the door, the user can control the limiter 130 to lock and unlock the cooking utensil. Specifically, when the door assembly 300 closes the cavity assembly 200, the locking member 120 is located in the locking position, and the locking member 120 is connected to the connecting portion 310 in the door assembly 300. At this time, the user can control the limiter 130 to switch to the first state, and the limiter 130 operating in the first state limits the locking member 120. At this time, the locking member 120 cannot move relative to the door assembly 300. Before opening the cavity assembly 200, the limiter 130 needs to be switched to the second state, and the limiter 130 in the second state is separated from the operating member locking member 120. At this time, the limiter 130 no longer limits the locking member 120, and the user can open the cavity assembly 200 by pulling the door assembly 300. Opening the cavity assembly 200 requires two steps, which is conducive to improving the safety of the cooking utensil.

[0077] In the present invention, a child lock structure is added to the cooking utensil. When the locking member 120 moves to the first position, the limiting member 130 limits the movement of the locking member 120. The locking member 120 limits the door body assembly 300, and the door body assembly 300 is difficult to open the cavity assembly 200, thereby keeping the door body in a locked state, and therefore the cavity assembly 200 cannot be opened.

[0078] In order to open the cavity assembly 200, it is necessary to release the position limit of the locking member 120 on the door assembly 300, so it is necessary to first release the position limit of the locking member 120 by the limiting member 130. When the limiting member 130 and the locking member 120 are separated, the locking member 120 can move relative to the mounting member 110, so that the position limit of the locking member 120 on the door assembly 300 can be released. Therefore, when opening the door, the user needs to first switch the limiting member 130 to the second state, which is the first step, and then pull the door assembly 300 to open the cavity assembly 200, which is the second step. The two-step operation increases the difficulty of opening the door.

[0079] After the cooking process of the cooking appliance is finished, the temperature of the food in the cooking cavity is high. At this time, if the user directly opens the door to take out the food, there is a risk of scalding. Therefore, the present invention uses the above-mentioned lock structure 100 so that if the user wants to open the cavity assembly 200, he must perform a two-step door opening operation before opening the cavity assembly 200. In this way, on the one hand, it can serve as a certain reminder to the user, and on the other hand, it can prevent children from accidentally opening the cavity assembly 200, thereby greatly improving the safety of the cooking appliance.

[0080] The locking member 120 and the limiting member 130 are mounted on the mounting member 110 , so the lock structure 100 is an integral structure, which facilitates the assembly of the lock structure 100 .

[0081] In this embodiment, the door body assembly 300 includes a door seal 320, a door tooth 330 and a door face 340 which are connected in sequence.

[0082] In the above embodiment, based on the installation member 110 being disposed on the cavity assembly 200 , the connection portion 310 includes a door hook.

[0083] When the mounting member 110 is disposed on the cavity assembly 200 , the locking member 120 is used in cooperation with the door hook.

[0084] Specifically, the mounting member 110 is locked on the cavity assembly 200, and when the door assembly 300 closes the cavity assembly 200, the locking member 120 is engaged with the door hook, and the locking member 120 limits the movement of the door hook, and it is difficult for the user to directly pull the door assembly 300. When the locking member 120 releases the limit on the door hook, the user can open the cavity assembly 200 by pulling the door assembly 300.

[0085] By setting the lock structure 100 in the above embodiment on the cooking appliance, it is possible to achieve two-step door opening and one-button unlocking, which plays a convenient role in single-handed door opening. A screen can be set on the cooking appliance and the operation can be controlled through the screen, which is simple, convenient and clear.

[0086] The cooking appliance may be an induction cooker, an oven, a steam-bake combination machine, etc.
