The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "center", "length", "width", "thickness", "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", and the like, as used herein, refer to an orientation or positional relationship indicated in the drawings, which is used for convenience in describing the present invention and for simplicity in description, and does not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, is not to be construed as limiting the present invention.

A cooking appliance 100 and a control method of the cooking appliance according to an embodiment of the present invention are described below with reference to the accompanying drawings.

Referring to fig. 1 to 6, a cooking appliance 100 according to an embodiment of the present invention includes: pot body assembly 10, first lid body assembly 20, detection assembly 40 and control device 50.

Specifically, as shown in fig. 2, the pot assembly 10 includes a body 11 and a food container 12, the food container 12 is removably disposed in the body 11, the food container 12 can contain food, or accessories for containing food, such as a baking container 60, can be placed in the food container 12. The first cover assembly 20 is detachably covered on the main body 11, so that the first cover assembly 20 can be detached for storage when the first cover assembly 20 is not required to be matched with the pot body assembly 10 for cooking. The first cover assembly 20 includes a first heating device 21, and the first heating device 21 can be used for heating food to achieve frying, roasting, frying and the like of the food.

The applicant has found that, since the first cover assembly 20 is provided with the first heating device 21 and the first cover assembly 20 can be separated from the pot body assembly 10, in the case that the first cover assembly 20 is not covered on the body 11 and the first heating device 21 is exposed, if the first heating device 21 is operated, the user is easily scalded or other nearby equipment is easily broiled. For example, when the user places the first cover assembly 20 on a placement surface such as a table, the first heating device 21 may be operated to damage the placement surface, or even cause a fire accident. In addition, when the first cover assembly 20 is covered on the main body 11 but the first cover assembly 20 is not covered with the main body 11, for example, the first cover assembly 20 is not fastened well, if the first heating device 21 works, the cooking efficiency is easily affected, and even a safety accident may happen seriously. In addition, in the case that the first cover assembly 20 is covered with the body 11 in place but the food container 12 is not assembled in the body 11, if the first heating device 21 is operated, the body 11 is directly heated, and the body 11 usually comprises a plastic structure, which is not resistant to high temperature, and high-temperature gas flows on the plastic structure, which may cause fire.

Therefore, in the embodiment of the present invention, as shown in fig. 4, 6 and 7, the detecting assembly 40 is configured to be able to detect the covering state of the first cover assembly 20 on the body 11 and the fitting state of the food container 12 in the body 11. Control device 50 is disposed in pan assembly 10 or first cover assembly 20, and control device 50 is connected to detection assembly 40.

The control device 50 controls the first heating device 21 not to operate under the condition that the detecting assembly 40 detects that the first cover assembly 20 is not covered in place, that is, the first cover assembly 20 is not matched with the main body 11 in place. The control means 50 also controls the first heating means 21 not to be operated in case it is detected that the food container 12 is not fitted in place, i.e. that the food container 12 is not placed in the body 11. In other words, the control device 50 controls the first heating device 21 not to be operated under the condition that the detecting assembly 40 detects that the first cover assembly 20 is not properly covered and/or the food container 12 is not properly fitted, so as to prevent safety accidents.

According to the cooking appliance 100 of the embodiment of the invention, the working state of the first heating device 21 is controlled according to the covering state of the first cover assembly 20 on the body 11 and the matching state of the food container 12 in the body 11, so that double protection is realized, other equipment such as a table top and the like are prevented from being burned or a user is prevented from being scalded due to the working of the first heating device 21 when the first cover assembly 20 is not covered on the body 11, a safety accident caused by the working of the first heating device 21 when the first cover assembly 20 is not tightly covered on the body 11 is also prevented, the risk of fire on the body 11 caused by the working of the first heating device 21 when the food container 12 is not installed in the body 11 is also prevented, and the cooking appliance 100 is safer to use. And the detection of the covering state of the first cover body assembly 20 and the matching state of the food container 12 can be realized through one part of the detection assembly 40, so that the structure of the cooking utensil 100 is simpler.

According to some embodiments of the present invention, the control device 50 controls the first heating device 21 to operate under the condition that the detecting assembly 40 detects that the first cover assembly 20 is covered in place and the food container 12 is fitted in place. Therefore, when the first cover assembly 20 is covered on the main body 11 and the food container 12 is fitted in place in the main body 11, the control device 50 can automatically control the first heating device 21 to work without additional operation by the user, and the cooking utensil 100 is more convenient and simple to use.

The present invention is not limited to a specific detection manner and a corresponding detection structure of the detection assembly 40. For example, the detecting component 40 may include a proximity switch, a micro switch, or a capacitance signal sensing switch, and the like, and an appropriate detecting manner may be flexibly selected according to actual needs, so as to achieve a better detecting effect.

According to some embodiments of the present invention, as shown in fig. 3-6, the detection assembly 40 includes: the switch element 41, the first movable element 42 and the second movable element 43, and the switch element 41, the first movable element 42 and the second movable element 43 are all disposed on the first cover assembly 20, and the first movable element 42 and the second movable element 43 can directly or indirectly trigger the switch element 41. The switch member 41 is electrically connected to the control device 50, so that the control device 50 can control the operating state of the first heating device 21 according to the detection result of the switch member 41. The first movable member 42 can be in abutting engagement with the main body 11 to detect the closed state of the first cover assembly 20. The second movable member 43 can be in abutting engagement with the food container 12 to enable detection of the engagement state of the food container 12.

The detecting assembly 40 is respectively matched with the body 11 and the food container 12 through two structures, namely the first moving member 42 and the second moving member 43, so that the interference between the detection of the covering state of the first cover assembly 20 and the detection of the matching state of the food container 12 can be avoided, and the detection accuracy is improved. The detection assembly 40 is electrically connected with the control device 50 through the switch 41 to control the working state of the first heating device 21, that is, the switch 41 identifies two abnormal working states, namely, the first cover assembly 20 is not covered in place and the food container 12 is not matched in place, so that the structure of the detection assembly 40 can be effectively simplified, the electrical connection structure of the cooking appliance 100 can be simplified, and the circuit connection can be simplified.

In some embodiments of the present invention, the body 11, when engaged with the first cover assembly 20, supports the first movable member 42 to ensure that the first cover assembly 20 is in the closed position, and the food container 12, when engaged with the first cover assembly 20, supports the second movable member 43 to ensure that the food container 12 is in the closed position. The switching member 41 controls the first heating device 21 to operate in a state where both the first movable member 42 and the second movable member 43 are lifted. When at least one of the first movable member 42 and the second movable member 43 is not jacked up, the switching element 41 controls the first heating device 21 to stop working, the first movable member 42 and the second movable member 43 have certain moving strokes, which is beneficial to reducing the occurrence of false triggering, and the detection structure is simple.

In some embodiments, as shown in fig. 2, the main body 11 includes a housing 112 and an insulated pot 113, the insulated pot 113 is disposed in the housing 112, the food container 12 is disposed in the insulated pot 113, and the housing 112 or the insulated pot 113 can lift up the first movable member 42 when the main body 11 is engaged with the first lid assembly 20.

In other embodiments, the body 11 includes a housing 112, and the food container 12 is disposed in the housing 112, and the housing 112 can jack up the first movable member 42 when the body 11 is engaged with the first cover assembly 20. Of course, in the embodiment that the main body 11 includes other structures, the first movable member 42 may be lifted by other structures of the main body 11 in the state that the main body 11 is engaged with the first cover assembly 20, and only the requirement of being able to detect the closed state of the first cover assembly 20 and the main body 11 needs to be satisfied.

According to some embodiments of the present invention, the body 11 has a first mating member 111 capable of mating against the first movable member 42, and the food container 12 has a second mating member capable of mating against the second movable member 43, so that the body 11 and the first movable member 42 can be conveniently mated, and the food container 12 and the second movable member 43 can be conveniently mated.

As shown in fig. 2, the first mating member 111 may be an upper surface of the body 11, for example, an upper surface of the housing 112 or an upper surface of the heat insulation pan 113, and no additional component for mating with the first movable member 42 is required on the body 11, which is beneficial to simplifying the structure of the body 11. The second mating member is the rim 121 of the food container 12, and no additional member for mating with the second movable member 43 is required on the food container 12, which is beneficial to simplifying the structure of the food container 12. For example, the body 11 and the food container 12 may be constructed as in the prior art, and the body 11 and the food container 12 may be mated with the detection assembly 40 without modification.

In the embodiment of the present invention, the switch member 41 may include a micro switch or a magnetic sensitive switch with a reed switch, etc. according to the actual requirement, and the structure of the switch member 41 is simple and sensitive, which is beneficial to improve the detection accuracy of the covering state of the first cover assembly 20 and the matching state of the food container 12.

For example, in some embodiments, referring to fig. 3-6, the switch element 41 comprises a micro switch that is activated when the first moveable member 42 is in abutting engagement with the body 11 and the second moveable member 43 is in abutting engagement with the food container 12, and the first heating device 21 is activated when the micro switch is activated and deactivated when the micro switch is deactivated. The micro switch is sensitive in response and is not easy to cause misoperation or failure.

Here, "the microswitch is triggered" means that the microswitch is operated to be in a triggered position, that is, the movable contact and the fixed contact of the microswitch are connected, and "the microswitch is not triggered" means that the microswitch is in a normal position, that is, the movable contact and the fixed contact are in a normal off position.

In some embodiments, the micro switch includes a switch body and a switch elastic sheet, the switch body is provided with a contact 411, and one end of the switch elastic sheet is connected to the switch body. The switch elastic sheet does not contact with the contact 411 when not deformed, and the switch elastic sheet can be deformed under the stop of the trigger 44 to contact with the contact 411 to trigger the switch body. Compared with the trigger stroke of the micro switch, the movable strokes of the first moving part 42, the second moving part 43 and the trigger part 44 are very large, so that the movement of the trigger part 44 in a large distance can be converted into the relative movement of a small distance between the switch elastic piece and the contact 411 by arranging the switch elastic piece, and the service life of the micro switch is prolonged. Of course, the trigger 44 may directly contact the contact 411 to trigger the contact 411 according to actual requirements, and this is within the protection scope of the present invention.

In some embodiments, the first and second

moveable members

42, 43 may directly activate the switching element 41. In other embodiments, the first and second

movable members

42, 43 may indirectly trigger the switching element 41, as shown in fig. 4 and 6, and the detection assembly 40 further includes a trigger element 44, the trigger element 44 being capable of triggering the switching element 41 upon simultaneous actuation of the first and second

movable members

42, 43. Therefore, the switch part 41 only needs to be matched with one part of the trigger part 44 to realize triggering and non-triggering, which is beneficial to simplifying the structure and the control logic of the switch part 41, reducing the occurrence of false triggering and improving the accuracy of control.

According to some embodiments of the present invention, the triggering member 44 is rotated by the first movable member 42 or the second movable member 43 alone without triggering the switching member 41, so as to avoid a false triggering condition. The triggering element 44 moves under the driving of the first moving element 42 and the second moving element 43 together to trigger the switching element 41, so as to ensure the accuracy and effectiveness of the detection.

According to some embodiments of the present invention, as shown in fig. 4 and 6, the trigger 44 includes: a mounting shaft 441, a first contact 442 and a second contact 443. The first contact 442 is disposed on the mounting shaft 441 and can be engaged with the first movable member 42 in an abutting manner, and the second contact 443 is disposed on the mounting shaft 441 and can be engaged with the second movable member 43 in an abutting manner. The mounting shaft 441 can be driven by the first movable member 42 or the second movable member 43 to rotate the trigger member 44, so as to not trigger the switch member 41, and the mounting shaft 441 can be driven by the first movable member 42 and the second movable member 43 to move the trigger member 44, so as to trigger the switch member 41.

In other words, when the first movable member 42 is in abutting engagement with the first contact 442 and the second movable member 43 is not in abutting engagement with the second contact 443, the mounting shaft 441 rotates and cannot move, and the trigger member 44 cannot trigger the switching member 41; in the case where the first movable member 42 is not abutted against the first contact 442 and the second movable member 43 is abutted against the second contact 443, the mounting shaft 441 rotates and cannot move, and the trigger member 44 cannot trigger the switching member 41; in the case where the first movable member 42 is in abutting engagement with the first contact 442 and the second movable member 43 is in abutting engagement with the second contact 443, the mounting shaft 441 can be moved, so that the trigger member 44 can be moved to trigger the switching member 41.

Therefore, the switch part 41 is not triggered to control the first heating device 21 not to work under the condition that the first cover body assembly 20 is not covered in place and/or the food container 12 is not matched in place, and the switch part 41 is triggered to control the first heating device 21 to work under the condition that the first cover body assembly 20 is covered in place and the food container 12 is matched in place are detected at the same time.

It should be noted that, in the embodiment of the present invention, the position of the triggering member 44 for triggering the switch member 41 can be flexibly arranged, for example, the switch member 41 can be triggered by the mounting shaft 441, the first contact 442, the second contact 443, or the connection between the mounting shaft 441 and the contact, which is within the protection scope of the present invention.

In some embodiments of the present invention, as shown in fig. 4, the first cover assembly 20 is provided with a mounting groove 203, the mounting groove 203 extends in an up-and-down direction, a part of the mounting shaft 441 can be assembled in the mounting groove 203, and the mounting shaft 441 can rotate and move up and down in the mounting shaft 441, so that the mounting groove 203 can provide a good guiding and limiting function for the mounting shaft 441, and the trigger 44 can accurately trigger and not trigger the switch element 41.

In some embodiments, referring to fig. 4, the first contact piece 442 and the second contact piece 443 are both sleeved on the mounting shaft 441, and the first contact piece 442 and the second contact piece 443 respectively extend toward both lateral sides of the mounting shaft 441, and the first movable member 42 and the second movable member 43 are respectively disposed on both lateral sides of the mounting shaft 441. Here, the lateral direction may be understood as a direction perpendicular to the axis of the mounting shaft 441.

For example, in the example shown in fig. 4, one end of the first contact 442 and one end of the second contact 443 are respectively fixedly connected to the mounting shaft 441, the other end of the first contact 442 and the other end of the second contact 443 are respectively located on both sides of the axis of the mounting shaft 441 in the horizontal direction, so that when the trigger 44 is not engaged with the first movable member 42 and the second movable member 43, the first contact 442 and the second contact 443 can balance the forces applied to the mounting shaft 441 in the horizontal direction, and the first contact 442 and the second contact 443 are substantially at the same height, so that the first movable member 42 can smoothly contact the first contact 442 when being lifted up, and the second movable member 43 can smoothly contact the second contact 443 when being lifted up.
