Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as specifically described herein, and thus the scope of the present invention is not limited by the specific embodiments disclosed below.

A lock structure and a cooking appliance 100 provided according to some embodiments of the present invention are described below with reference to fig. 1 to 25.

As shown in fig. 2, 4, 5 and 7, a first embodiment of the present invention provides a lock structure including a fixing member 106 and a locking assembly 108. The locking assembly 108 and the fixing member 106 can cooperate to function as a locking and limiting device. Specifically, as shown in fig. 1 and 2, the lock structure proposed by the present invention may be applied to the cooking appliance 100 and used as a child lock of the cooking appliance 100.

In particular, as shown in fig. 7, 8 and 12, the locking assembly 108 includes a mounting member 110, a driving member 112, a first resilient member 114 and a locking member 116. Among them, the mounting member 110 is an external object (for example, the door assembly 104 or the cavity assembly 102 of the cooking appliance 100); as shown in fig. 7 and 12, at least a portion of the driving member 112 is disposed in the mounting member 110, and a first end of the first elastic member 114 is connected to the driving member 112; the second end of the first elastic member 114 is connected to the locking member 116. Thus, the driving member 112 can apply a pushing force to the locking member 116 through the first elastic member 114, so that the locking member 116 moves relative to the mounting member 110 under the driving of the driving member 112 and the first elastic member 114, and the locking member 116 passes through the mounting member 110 to be locked with the fixing member 106.

In particular, in the lock structure proposed by the present invention, as shown in fig. 7 and 12, the first elastic member 114 abuts between the driving member 112 and the locking member 116, thereby achieving flexible connection between the locking member 116 and the driving member 112. Thus, when the locking assembly 108 is in the locked position, the locking member 116 can still move toward the driving member 112 due to the first elastic member 114.

Specifically, as shown in fig. 7 and 12, the fixing member 106 and the locking assembly 108 can be respectively mounted to the door assembly 104 of the chamber body assembly 102, so that, when the door assembly 104 is opened, once the user unintentionally closes the locking assembly 108, without switching the working position of the locking member 116, the fixing member 106 can contact the locking member 116 during the process of closing the door assembly 104 by the user, and further, the locking member 116 is forced to move toward the driving member 112 side.

Like this, can guarantee on the one hand that locking piece 116 and mounting 106 can be connected spacingly, on the other hand locking piece 116 and mounting 106 be connected spacingly and need not user operation, have promoted locking assembly 108's use convenience to a great extent.

As shown in fig. 1, when the door body assembly 104 is in the closed state, the lock member 116 is in the locking position; at this time, the locking member 116 is connected with the fixing member 106 for limiting, and the user cannot open the door body assembly 104. Before the door body assembly 104 is opened, the connection limit between the locking part and the fixing part 106 is released; at this time, the locking member 116 is in the unlocking position, and the locking member 116 is separated from the fixing member 106.

As shown in fig. 2, in the process of opening the door assembly 104, the door assembly 104 can be directly driven to be separated from the cavity assembly 102, so as to complete the door opening operation; at this point, the latch member 116 is still in the unlatched position. In the process of closing the door body assembly 104, the station of the locking piece 116 can be switched again after the door body assembly 104 is directly closed, so that the locking piece 116 and the fixing piece 106 are locked and limited.

As shown in fig. 7 and 12, once the user switches the locking member 116 to the locking position when the door assembly 104 is opened, the first elastic member 114 abuts between the locking member 116 and the driving member 112, so that the locking member 116 and the driving member 112 are elastically connected. Therefore, a user does not need to switch the station of the locking piece 116 in advance, and the locking piece 116 can still be locked and limited with the fixing piece 106 in the closing process of the door body assembly 104.

In particular, the lock structure proposed by the present invention can be applied to the cooking appliance 100. After cooking utensil 100 finishes the cooking process, the temperature of food in the cooking cavity is higher, and there is the risk of scalding this moment user directly opens the door body and takes out food. Therefore, the locking assembly 108 and the fixing member 106 are engaged, so that when a user wants to open the door assembly 104, the user must pull the locking member 116 while opening the door assembly 104. Therefore, on the one hand, a certain prompting effect can be achieved for the user, on the other hand, the situation that the door body assembly 104 is opened by mistake by a child can be prevented, and the use safety of the cooking appliance 100 is greatly improved.

Therefore, the locking structure provided by the present invention, through the cooperation of the locking assembly 108 and the fixing member 106, increases the unlocking difficulty of the locking structure, prevents a user, especially a child, from opening the door assembly 104 by mistake, and increases the safety of the cooking appliance 100 using the locking structure. Moreover, the driving member 112 is flexibly connected with the locking member 116, so that when the door body assembly 104 is opened, even if a user mistakenly switches the locking member 116 to the locking position, the door body assembly 104 can be closed without driving the locking member 116, and the connection limit between the locking member 116 and the fixing member 106 is ensured.

A second embodiment of the present invention provides a lock structure, further comprising, based on the first embodiment:

When the user presses the pressing piece 120, the first slope 124 of the pressing piece 120 is in contact with the second slope 126 of the mover 122.

As shown in fig. 12, when the pressing member 120 is pressed for the first time, the moving member 122 moves along the guide structure 118; when the moving member 122 moves to the end of the guiding structure 118, the second inclined surface 126 and the first inclined surface 124 cooperate to drive the moving member 122 to rotate, and at this time, the moving member 122 can abut against the limiting portion, and the locking member 116 is limited at the locking position.

As shown in fig. 12, when the pressing member 120 is pressed for the second time, the second inclined surface 126 cooperates with the first inclined surface 124 to drive the moving member 122 to rotate again, and at this time, the moving member 122 moves along the guiding structure 118 in the opposite direction, so that the moving member 122 is separated from the limiting portion, and the locking member 116 is switched from the locking position to the unlocking position.

A fourth embodiment of the present invention provides a lock structure, and based on the third embodiment, further:

as shown in fig. 12 and 13, the pressing piece 120 includes a key post. The side wall of the key post is provided with a third protrusion 166 which can abut against the end of the mounting member 110, so as to ensure that at least a part of the mounting post is always located inside the mounting member 110, and further ensure that the key post is connected with the mounting member 110.

Specifically, during the use, because first elastic component butt in the lock piece and the motion piece between. Thus, the third protrusion 166 is in contact with the mounting member for limiting, so that the key post is prevented from being separated from the mounting member by the elastic force of the first elastic member.

As shown in fig. 12 and 14, the mover 122 includes a claw sleeve. The side wall of the sliding claw sleeve is provided with a first protrusion 128, the first protrusion 128 is connected with the guide structure 118 in a sliding manner, and the first protrusion 128 can abut against the end of the guide structure 118, so that the locking member 116 is limited at the locking position.

Specifically, as shown in fig. 12 and 14, the inside of the key post is hollow, and at least a part of the claw sleeve can protrude into the inside of the key post. In addition, the first inclined surface 124 is disposed at the opening end of the key post, and the second inclined surface 126 is disposed at the first protruding portion.

When the pressing member 120 is pressed for the first time, the first protrusion 128 drives the moving member 122 to move along the guide structure 118; when the moving member 122 moves to the end of the guiding structure 118, the second inclined surface 126 cooperates with the first inclined surface 124 to drive the moving member 122 to rotate, and at this time, the first protrusion 128 can abut against the limiting portion, and the locking member 116 is limited in the locking position.

When the pressing member 120 is pressed for the second time, the second inclined surface 126 cooperates with the first inclined surface 124 to drive the moving member 122 to rotate again, and at this time, the moving member 122 moves along the guiding structure 118 in the opposite direction under the action of the first elastic member 114, so that the moving member 122 is separated from the limiting portion, and the first protrusion 128 is switched from the locking position to the unlocking position.

In a specific embodiment, as shown in fig. 13 and 14, the first inclined surface 124 may be a serrated inclined surface on the key post, and the second inclined surface 126 may be a serrated inclined surface on the moving element. In addition, the first inclined surface 124 and the second inclined surface 126 defined by the present invention are not limited to the above-mentioned saw-toothed inclined surfaces as long as they can cooperate with the inclined surfaces for driving the locking member to rotate and move, and those skilled in the art will also understand that.

Further in this embodiment, the interior of the mover 122 is hollow, and at least a portion of the lock member 116 is located inside the mover 122. In addition, the side wall of the moving member 122 is provided with a guide groove 170, and the extending direction of the guide groove 170 is consistent with the moving direction of the locking member 116; the locking member 116 is provided with a second protrusion 130, the second protrusion 130 is located in the guide groove 170, and the second protrusion 130 is slidably connected with the guide groove 170.

Thus, in use, locking member 116 is movable relative to movable member 122 by an external force, thereby ensuring that locking member 116 can be retracted into mounting member 110 even if a user inadvertently closes locking assembly 108, thereby ensuring that locking member 116 and mounting member 106 can be coupled in a limited position.

Specifically, when the door body assembly 104 is opened, the first elastic member 114 abuts between the moving member 122 and the lock member 116. At this time, the second protrusion 130 is located at the middle of the guiding slot 170 or at the first end of the guiding slot 170 close to the bottom of the mounting member 110, so as to ensure that the locking member 116 can be retracted into the mounting member 110 under the driving of an external force, and further ensure that the locking member 116 can still be locked with the fixing member 106 even if the user closes the locking assembly 108 accidentally.

In addition, at the activity of locking piece 116 removal, second convex part 130 removes along guide way 170, and then plays certain spacing and guide effect through the cooperation of second convex part 130 with guide way 170, and then promotes the operation flat and stable of locking piece 116.

A fifth embodiment of the present invention provides a lock structure, further comprising, based on the first embodiment:

At this time, in the process of closing the door assembly 104, the user can directly drive to close the door assembly 104 without pressing the pressing piece 120 again, which is more convenient for the user to operate.

Specifically, in the process that the user closes the door body assembly 104, the fixing member 106 first contacts with the driving inclined surface 132 of the locking member 116, the driving inclined surface 132 decomposes the force applied by the fixing member 106 to the locking member 116 into a transverse component force and a vertical component force, and the vertical component force can be used for offsetting the pushing force applied by the first elastic member 114 to the locking member 116, so that the locking member 116 moves under the action of the vertical component force, and the locking member 116 retracts into the mounting member 110. At this time, the user can close the door assembly 104.

A sixth embodiment of the present invention provides a lock structure, further comprising, based on the first embodiment:

as shown in fig. 7 and 12, the locking assembly 108 further includes a second resilient member 134. The second elastic element 134 is disposed in the mounting element 110 and abuts against the moving element 122 of the driving element 112 and the cover plate 140 of the mounting element 110. Thus, the first elastic member 114 and the second elastic member 134 cooperate to further improve the stability of the locking member 116.

In particular, in the process of pressing the pressing member 120, before the pressing member 120 contacts the moving member 122, the pressing member 120 presses the second elastic member 134, and the second elastic member 134 is in a compressed state; after the pressing member 120 contacts the moving member 122, the pressing member 120 simultaneously presses the first elastic member 114 and the second elastic member 134, and both the first elastic member 114 and the second elastic member 134 are in a compressed state.

As shown in fig. 7 and 12, when the moving element 122 is limited at the end of the guiding structure 118, the first elastic element 114 and the second elastic element 134 in a compressed state both apply a pushing force to the moving element 122, so that the moving element 122 is stably limited at the end of the guiding structure 118. After pressing the pressing piece 120 again, the mover 122 rotates and disengages from the end of the guide structure 118; at this time, the first elastic member 114 and the second elastic member 134 are engaged with each other in the compressed state, thereby restoring the moving member 122 to the previous position. In this process, due to the cooperation of the first elastic member 114 and the second elastic member 134, the thrust force on the driving member 112 can be greatly increased, and the stability of the locking member 116 can be further improved.

On the basis of any of the above embodiments, further, as shown in fig. 1 and fig. 2, the cooking appliance 100 of the present invention includes, but is not limited to: a microwave oven, an oven, a steam box, or a steaming and baking all-in-one machine.

In addition to any of the above embodiments, as shown in fig. 1, 2, 3 and 4, the locking assembly 108 is a child lock.

In addition to any of the above embodiments, as shown in fig. 7 and 12, in the cooking appliance 100 of the present invention, the first elastic member 114 includes a spring; the second elastic member 134 includes a spring; the locking member 116 includes a latch; the fastener 106 includes a locking pin having a fastening opening 164 formed in a middle portion thereof.

On the basis of any of the above embodiments, as shown in fig. 8, 9, 10, 11 and 22, when the locking assembly 108 is disposed on the cover 146, the shape of the mounting member 110 of the locking assembly 108 is more flexible.

On the basis of any of the above embodiments, further, as shown in fig. 16, 17, 18 and 19, when the locking assembly 108 is disposed on the door body 148, the mounting member 110 of the locking assembly 108 needs to have a certain protrusion, so as to ensure that the mounting member 110 can be connected with the door body 148, and avoid the influence on the installation of the locking assembly 108 due to the excessive thickness of the door body 148.

After cooking appliance 100 finishes cooking, a user can directly open door body assembly 104, and the temperature of food just cooked is often higher, so that the possibility of scalding the user exists. Especially, when children cook food using the cooking appliance 100, accidents are more likely to occur.

In addition to any of the above embodiments, as shown in fig. 4, when the locking assembly 108 is disposed on the cavity assembly 102 and the fixture 106 is disposed on the door body assembly 104, the end plate 154 of the cavity assembly 102 is provided with an insertion opening 168, and the fixture 106 can extend into the insertion opening 168 to ensure that the fixture 106 is locked with the locking member 116.

As shown in fig. 1, 2, 3, 4 and 5, the cooking utensil 100 of the present invention is provided with a lock structure, and before the door is pushed or pulled, the connection between the locking assembly 108 and the fixing member 106 must be released to complete the whole door opening operation.

In the cooking appliance 100 of the present invention, the pressing type locking assembly 108 is matched with the fixing member 106, and the pressing type locking assembly 108 can effectively prevent the door assembly 104 from being closed due to the mistaken touch of the locking assembly 108 after the door assembly 104 is opened.

Specifically, as shown in fig. 12, the locking assembly 108 includes a pressing member 120, a moving member 122, a locking member 116, a latch, a fixing bracket 136 with a guide structure 118, a first elastic member 114, a second elastic member 134, a cover plate 140, and the like. Wherein the fixing bracket 136 is then fixed to the external structure by means of screws. When the door body assembly 104 is in a closed state, the locking piece 116 extends downwards into the fixing port 164 of the fixing piece 106 after the pressing piece 120 is pressed, and the door cannot be opened only by pulling the handle of the door body assembly 104 or only pressing the door opening button of the door body assembly 104.

When the pressing member 120 is pressed for the first time, the pressing member 120 pushes the moving member 122 to compress the first elastic member 114 and the second elastic member 134, and after the moving member 122 moves along the guide structure 118 to the critical point of the tip of the bottom of the guide structure 118, the moving member 122 rotates to the right side and is stuck to the end of the fixed guide structure 118. In the process, the lower locking member 116 is subjected to the first elastic force of the compressed first elasticity to move downward along the guiding structure 118 until the lowest end of the guiding structure 118 is reached, at which time the locking member 116 enters the fixing opening 164 of the fixing member 106, and the locking operation of the locking structure is completed.

When the pressing member 120 is pressed for the second time, after the pressing member 120 pushes the moving member 122 to move to the critical point of the tip of the guiding structure 118 of the fixing bracket 136, the moving member 122 will tend to return back into the guiding structure 118 and will move back to the top along the guiding structure 118 due to the spring force provided by the first elastic member 114 and the second elastic member 134; at this time, the locking member 116 is further away from the fixing opening 164 of the fixing member 106, thereby completing the locking operation of the lock structure.

The locking and unlocking operations of the lock structure are performed by pressing the pressing member 120 to move the locking member 116 into and out of the fixing hole 164 of the fixing member 106. To complete the closure of the door assembly 104, the latch structure must be unlocked.

Further, as shown in fig. 1, when the door assembly 104 is in an open state, and there is a situation that the locking assembly 108 is locked due to the pressing member 120 being touched by mistake, subsequently, in the process of closing the door assembly 104, the inclined surface of the fixing member 106 starts to act on the driving inclined surface 132 of the locking member 116 by a vertical inclined force, and then the vertical force can be decomposed into a vertical force and a horizontal force, and the vertical force can be decomposed to make the locking member 116 have an upward force, so that the locking member 116 can compress the elastic first elastic member 114 to move upward. As shown in fig. 2, after the door body assembly 104 is closed, the compressed first elastic member 114 acts on the locking member 116, so that the locking assembly 108 is locked again.

In particular embodiments, the locking assembly 108 and the fastener 106 may have a variety of mounting configurations. Specifically, as shown in fig. 24, the locking assembly 108 may be mounted to the housing of the chamber body assembly 102 by screws or the like; as shown in fig. 25, the locking assembly 108 is also mounted to the end plate 154 of the chamber body assembly 102 by screws or the like.

Specifically, as shown in fig. 21, the fixing member 106 may be an integral structure with the door seal 150 of the door body assembly 104; as shown in fig. 22, the fixing member 106 may also be a separate structure, and is assembled to the door seal 150 of the door body assembly 104 by means of screws or the like; as shown in fig. 23, the fixing member 106 may be a separate structure, and the fixing member 106 may be assembled to the door body 148 of the door body assembly 104 by means of screws or the like.
