Description

Technical Field

[0001] The present invention relates to the field of small household appliances, and in particular to a cooking utensil. Background Art

[0002] Electric pressure cookers are widely used by consumers because of their high cooking pressure and fast cooking speed. At present, electric pressure cookers are equipped with a pressure detection safety mechanism. When the pressure in the pot is greater than or equal to the preset pressure, the lid cannot be opened. When the pressure in the pot is less than the preset pressure, the lid can be opened to ensure the safety of the user. However, since the electric pressure cooker has a very good heat preservation effect, the temperature in the pot remains very high for a period of time after cooking. At this time, if the lid is opened by mistake or if you are not careful and get too close to the pot mouth, a large amount of hot air will come out when the lid is opened, which may cause the risk of scalding the user. Therefore, the safety of electric pressure cookers on the market is relatively poor. Summary of the invention

[0003] The main purpose of the present invention is to provide a cooking appliance to solve the problem of poor safety of the cooking appliances in the prior art.

[0004] In order to achieve the above-mentioned objectives, the present invention provides a cooking utensil, comprising: a pot body, having a cooking cavity; a pot cover, which is openably and closably arranged on the pot body; a cover opening member, which can drive the pot cover to move from a closed position to an open position; a cover opening confirmation key, if the cover opening confirmation key receives a first trigger signal for confirming to open the lid, the cover opening member can drive the pot cover to move from the closed position to the open position, if the cover opening confirmation key does not receive the first trigger signal, the cover opening member cannot drive the pot cover to move from the closed position to the open position; and a heating device, which is used to heat the food in the cooking cavity.

[0005] Furthermore, a control panel is provided in the pot body or the pot lid. If the lid opening confirmation key receives the first trigger signal, the lid opening confirmation key can send a second trigger signal to the control panel.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] like Figures 1 to 13 As shown, the cooking appliance of the first embodiment includes: a pot body, a pot cover 10, a lid opening member 20, a lid opening confirmation key 30 and a heating device. The pot body has a cooking cavity; the pot cover 10 is openably and closably arranged on the pot body; the lid opening member 20 can drive the pot cover 10 to move from a closed position to an open position; if the lid opening confirmation key 30 receives a first trigger signal for confirming the opening of the lid, the lid opening member 20 can drive the pot cover 10 to move from a closed position to an open position; if the lid opening confirmation key 30 does not receive the first trigger signal, the lid opening member 20 cannot drive the pot cover 10 to move from a closed position to an open position. The heating device is used to heat the food in the cooking cavity.

[0038] The technical solution of the first embodiment is applied, and the cooking appliance is provided with a lid opening confirmation key 30, and the lid opening member 20 can drive the pot cover 10 to move from the closed position to the open position. If the lid opening confirmation key 30 does not receive the first trigger signal, the lid opening member 20 cannot drive the pot cover 10 to move from the closed position to the open position. The above structure requires the user to perform a step of confirming whether to open the lid before opening the lid through the lid opening member 20, thereby preventing the user from being scalded due to opening the lid by mistake, and solving the problem of poor safety of the electric pressure cooker in the prior art.

[0039] It should be noted that in the first embodiment, the cooking utensil is an electric pressure cooker, the pot cover 10 is provided with a cover tooth, and the pot body is provided with a pot tooth. When the cover tooth and the pot tooth are matched, the pot cover 10 is in a closed position, and when the cover tooth and the pot tooth are separated, the pot cover 10 is in an open position. Of course, the matching form of the pot body and the pot cover is not limited to the pot tooth and the cover tooth. In other embodiments, the pot cover 10 may be provided with a first buckle hook, and the pot body may be provided with a second buckle hook. When the first buckle hook and the second buckle hook are matched, the pot cover 10 is in a closed position, and when the first buckle hook and the second buckle hook are separated, the pot cover 10 is in an open position.

[0040] In the first embodiment, a control panel (not shown in the figure) is arranged in the pot body or the pot cover 10. If the lid opening confirmation key 30 receives the first trigger signal, the lid opening confirmation key 30 can send a second trigger signal to the control panel. If the control panel receives the second trigger signal, the lid opening member 20 can drive the pot cover 10 to move from the closed position to the open position. The above structure is controlled by the control panel, so that the structure is simple, the response speed is fast, and it is convenient for users to operate. In other embodiments, a purely mechanical structure can also be used. For example, the lid opening confirmation key is movably arranged on the pot cover. When the user presses the lid opening confirmation key and operates the lid opening member, the lid opening confirmation key interferes with the lid opening member, so that the lid opening member cannot drive the pot cover 10 to move from the closed position to the open position. When the lid opening confirmation key is reset, the lid opening confirmation key and the lid opening member do not interfere with each other. At this time, the lid opening member can drive the pot cover 10 to move from the closed position to the open position.

[0041] like Figure 1 and Figure 2 As shown, in the first embodiment, a panel 11 is provided on the pot body or pot cover 10, and a cover opening operation part is provided on the panel 11, and the cover opening operation part forms a cover opening confirmation key 30. When cooking is finished, the user can press the cover opening operation part on the panel 11, and the action of pressing the cover opening operation part is the first trigger signal. When the cover opening confirmation key 30 receives the first trigger signal, the cover opening member 20 can drive the pot cover 10 to move from the closed position to the open position to realize the cover opening. The above structure is simple and convenient for the user to operate. Preferably, in this embodiment, when the cooking is completed for a predetermined time or the pressure in the cooking cavity is less than the predetermined pressure, the position corresponding to the cover opening operation part on the panel 11 lights up to remind the user that the cover can be opened at this time.

[0042] It should be noted that in the first embodiment, the action of pressing the lid opening operation part is the first trigger signal. However, the first trigger signal is not limited thereto, and can also be a sound signal or an image signal. For example, if the user makes a sound of "open the lid", this sound is the first trigger signal. If the control panel receives this sound signal, the lid opening member 20 can drive the pot lid 10 to move from the closed position to the open position.

[0043] like Figures 2 to 10 As shown, in the first embodiment, the pot cover 10 includes a surface cover 12, an inner lining 13 and a rotatable inner cover which are arranged in sequence from the outside to the inside, and the cover opening member 20 drives the inner cover to rotate so that the pot cover 10 moves from a closed position to an open position.

[0044] like Figures 2 to 10 In the first embodiment, the cover opening member 20 is pivotally arranged on the inner liner 13 and connected to the inner cover to drive the inner cover to rotate relative to the inner liner 13. The above structure is simple and easy to open and close the pot cover.

[0045] like Figures 3 to 8 As shown, in the first embodiment, the cooking appliance further includes: an electromagnet 40 and a stopper 50. If the control panel receives the second trigger signal, the control panel can send a control signal to the electromagnet 40 to control the electromagnet 40 to be powered on or off. The stopper 50 can be arranged in a floating manner. When the electromagnet 40 is powered off, the stopper 50 can be stopped between the cover opening member 20 and the lining 13 to keep the cover opening member 20 in the initial position. When the electromagnet 40 is powered on, the stopper 50 can be moved away from the lining 13 under the action of the magnetic force generated by the electromagnet 40 to enable the cover opening member 20 to rotate. The above structure is simple, the production cost is low, and the space occupied is small.

[0046] like Figures 3 to 13 As shown, in the first embodiment, the cover opening member 20 includes a rotating rod 22, a mounting hole 21 is provided on the rotating rod 22, a stopper 50 is a float penetrating in the mounting hole 21, and a clamping hole 131 opposite to the electromagnet 40 is provided on the lining 13. When the pot cover 10 is in the closed position, the mounting hole 21 can be coaxial with the clamping hole 131, and the float can extend into the clamping hole 131 under the action of its own gravity. At this time, the user rotates the cover opening member 20, and the cover opening member 20 cannot rotate because the side wall of the float will abut against the clamping hole 131, so that the cover opening member 20 can be kept in the initial position. The above structure is simple and easy to process. When unlocking is required, the user puts a finger on the cover opening operation part, and the cover opening operation part sends a second trigger signal to the control board. After receiving the second trigger signal, the control board controls the electromagnet 40 to be energized, and the electromagnet 40 can attract the float after being energized, so that the float is away from the clamping hole 131. Since the float no longer abuts against the hole wall of the locking hole 131 , the user can smoothly rotate the cover opening member 20 to finally open the cover.

[0047] As the rotating rod 22 rotates, the float will gradually move away from the electromagnet 40. Therefore, when the rotating rod 22 moves to a certain position, the magnetic attraction between the electromagnet 40 and the float may not be sufficient to overcome the float's own gravity. At this time, the float will fall under the action of its own gravity. As the rotating rod 22 continues to rotate, the bottom of the float will contact the lining 13. However, due to the complex structure and many ribs of the lining 13, the bottom of the float may interfere with the ribs on the lining during the rotation of the rotating rod, resulting in poor rotation of the rotating rod 22. In order to solve the above problems, Figure 8 and Fig.11 As shown, in the first embodiment, the inner liner 13 is provided with an arcuate rib 132, and the clamping hole 131 is provided on the upper surface of the arcuate rib 132. When the rotating rod 22 rotates to a predetermined position, the float falls to the upper surface of the smooth arcuate rib 132 under the action of its gravity. The above structure prevents the float from interfering with other structures during the rotation of the rotating rod, thereby improving the smoothness of the rotation of the rotating rod 22.

[0048] like Figures 1 to 11 As shown, in the first embodiment, the electromagnet 40 has a power-on state and a power-off state. The stopper 50 can be arranged in a floating manner. If the electromagnet 40 is in the power-off state, the stopper 50 can be stopped between the cover opening member 20 and the pot cover 10 to keep the cover opening member 20 in the initial position. If the electromagnet 40 is in the power-on state, the stopper 50 can move to a position that does not interfere with the pot cover 10 and / or the cover opening member 20 under the action of the magnetic force generated by the electromagnet 40, so that the cover opening member 20 can drive the pot cover 10 to move from the closed position to the open position.

[0049] The technical solution of the first embodiment is applied, and the cooking utensil includes an electromagnet 40 and a stopper 50. When the electromagnet 40 is powered off, the stopper 50 can be stopped between the cover opening member 20 and the pot cover 10. At this time, the cover opening member 20 cannot be displaced relative to the pot cover 10 under the action of the stopper 50, and thus the pot cover 10 cannot be driven to move from the closed position to the open position. When the electromagnet 40 is powered on, the stopper 50 can be moved to a position that does not interfere with the pot cover 10 and / or the cover opening member under the action of the magnetic force generated by the stopper 50 and the electromagnet 40. At this time, since the stopper 50 is no longer stopped between the cover opening member 20 and the pot cover 10, the cover opening member 20 can be displaced relative to the pot cover 10, and thus the pot cover 10 can be driven to move from the closed position to the open position. In the above structure, since the user needs to control the electromagnetic valve before opening the cover, that is, control the on and off of the electromagnetic valve, it is equivalent to adding a step of confirming whether to open the cover before opening the cover, thereby preventing the user from being scalded due to opening the cover by mistake, and solving the problem of poor safety of the electric pressure cooker in the prior art. In addition, the above structure is simple, and the production cost of the electromagnet 40 and the stopper 50 is low, so that the cooking utensil having the same is not only safe, but also has low production cost.

[0050] like Figures 2 to 9 As shown, in the first embodiment, the pot cover 10 includes a surface cover 12, an inner lining 13 and a rotatable inner cover arranged in sequence from the outside to the inside, and the cover opening member 20 is pivotally arranged on the inner lining 13 and connected to the inner cover to drive the inner cover to rotate relative to the inner lining 13. If the electromagnet 40 is in a powered state, the stopper 50 can move to a position that does not interfere with the pot cover 10 and / or the cover opening member 20 under the action of the magnetic force generated by the electromagnet 40, so that the cover opening member 20 can rotate. The above structure is simple and easy to implement.

[0051] like Figures 2 to 9 As shown, in the first embodiment, the cover opening member 20 includes a rotating rod 22, which is pivotally arranged on the inner lining 13 and connected to the inner cover to drive the inner cover to rotate relative to the inner lining 13, and the stopper 50 is floatingly arranged on the rotating rod 22, and the electromagnet 40 is arranged on the inner lining 13 and located above the stopper 50. When the electromagnet 40 is in the power-on state, the stopper 50 can be moved away from the inner lining 13 under the action of the magnetic attraction generated by the electromagnet 40. The above structure is simple and easy to implement.

[0052] like Figures 2 to 13 As shown, in the first embodiment, a mounting hole 21 is provided on the rotating rod 22, the stopper 50 is a float penetrated in the mounting hole 21, and a clamping hole 131 opposite to the electromagnet 40 is provided on the lining 13. When the pot cover 10 is in the closed position, the mounting hole 21 can be coaxial with the clamping hole 131, and the float extends into the clamping hole 131 under the action of its own gravity to keep the cover opening member 20 in the initial position.

[0053] like Fig.12 and Fig.13 As shown, in the first embodiment, the rotating rod 22 includes a rotating rod body 221 and a lug 222 disposed on the side wall of the rotating rod body 221, and the mounting hole 21 is disposed on the lug 222. The above structure is simple and easy to process.

[0054] like Figure 4 , Figure 5 , Figure 8 and Fig.12 As shown, in the first embodiment, the float includes a post 51 and a ferromagnetic part 52 arranged at the first end of the post 51, the lower surface of the ferromagnetic part 52 can abut against the upper surface of the lug 222 to prevent the float from slipping out of the mounting hole 21 downward, and an annular convex edge 511 is arranged on the side wall of the second end of the post 51, the upper surface of the annular convex edge 511 can abut against the lower surface of the lug 222 to prevent the float from slipping out of the mounting hole 21 upward, and the second end of the post 51 can extend into the clamping hole 131. The above structure is simple and easy to assemble. Preferably, in the first embodiment, the ferromagnetic part 52 is a screw. The above structure is simple and low in cost.

[0055] like Figure 5 , Fig.10 , Fig.11 and Fig.14 As shown, in the first embodiment, a limiting structure 60 is provided between the electromagnet 40 and the pot cover 10 to limit the rotation of the electromagnet 40 , and the electromagnet 40 is fixed to the pot cover 10 by a fastener 70 .

[0056] According to the technical solution of the first embodiment, a limiting structure 60 capable of limiting the rotation of the electromagnet 40 along its circumferential direction is provided between the electromagnet 40 and the pot cover 10. When installing the electromagnet 40, since the electromagnet 40 has been limited in the circumferential direction by the limiting structure 60, the installer only needs one hand to install the fastener 70. The above structure makes the installation of the electromagnet 40 simple and convenient, frees the other hand of the installer, improves the installation efficiency, and reduces the labor intensity.

[0057] like Fig.11 and Fig.14 As shown, in the first embodiment, the limiting structure 60 includes a protrusion 61 and a groove 62 that cooperate with each other, one of the protrusion 61 and the groove 62 is arranged on the pot cover 10, and the other of the protrusion 61 and the groove 62 is arranged on the electromagnet 40. The above structure is simple and easy to process.

[0058] like Fig.11 and Fig.14As shown, in the first embodiment, the pot cover 10 is provided with a mounting post 133, the electromagnet 40 includes an electromagnet body 41 and an electromagnet lug 42 arranged on the side wall of the electromagnet body 41, the fastener 70 is penetrated through the electromagnet lug 42 and the mounting post 133, the protrusion 61 is arranged on the lower surface of the electromagnet lug 42, and the groove 62 is arranged on the upper end surface of the mounting post 133. Preferably, the fastener 70 is a screw. When installing the electromagnet 40, the electromagnet 40 is first rotated so that the mounting hole on the electromagnet lug 42 is opposite to the mounting hole on the mounting post 133, and the protrusion 61 is opposite to the groove 62. Then the electromagnet 40 is lowered so that the lower surface of the electromagnet lug 42 is attached to the upper surface of the mounting post 133. Finally, the screw is screwed into the mounting hole on the electromagnet lug 42 and the mounting hole on the mounting post 133, and the fixation of the electromagnet 40 is achieved. When the screw is screwed and the electromagnet 40 has a tendency to rotate relative to the mounting post 133 , the side wall of the protrusion 61 abuts against the groove wall of the groove 62 to limit the rotation of the electromagnet 40 .

[0059] like Figure 5 , Fig.10 , Fig.11 and Fig.14 As shown, in the first embodiment, the protrusion 61 is in a strip shape, one end of the protrusion 61 in the length direction is connected to the side wall of the electromagnet body 41, and the protrusion 61 extends toward the mounting hole for inserting the fastener 70. The above structure is simple and easy to process.

[0060] When the cooking is finished, the pressure in the cooking cavity is very high. If the lid is opened at this time, it will seriously endanger the safety of the user. Therefore, in the first embodiment, a stopper (not shown in the figure) is provided on the inner cover. When the pressure in the cooking cavity is greater than or equal to a predetermined pressure, the stopper can stop the lid opening member 20 so that the lid opening member 20 cannot drive the pot lid 10 to move from the closed position to the open position. When the pressure in the cooking cavity is less than the predetermined pressure, the stopper is far away from the lid member 20, so as not to affect the rotation of the lid opening member 20. The above structure can improve the safety of the cooking utensil.

[0061] It should be noted that in the first embodiment, after cooking is completed, the pressure in the cooking cavity is detected. When the pressure in the cooking cavity is less than the predetermined pressure, the cover opening operation part on the panel 11 will light up. At this time, the user is reminded that the cover opening operation can be performed. The above structure can inform the user whether the cover can be opened, and avoid the situation where the user rotates the cover opening member 20 hard when the pressure in the cooking cavity is high, thereby improving the user's experience. In addition, when the pressure in the cooking cavity is greater than or equal to the predetermined value, the stopper and the stopper 50 can jointly limit the rotation of the cover opening member 20, so as to further improve the safety of the cooking appliance.

[0062] like Fig.15 and Fig.16As shown, the difference between the cooking utensil of the second embodiment and the cooking utensil of the first embodiment lies in the specific structure of the cover opening confirmation key 30. Specifically, in the second embodiment, a fingerprint key is provided on the cover opening member 20, and the fingerprint key forms the cover opening confirmation key 30. The user can enter his fingerprint into the cooking utensil in advance before using the cooking utensil. When the cover needs to be opened, just place the finger on the fingerprint key. The above structure can prevent strangers or children who are not familiar with the cooking utensil from opening the cover, and prevent the heat when opening the cover from causing harm to strangers or children, thereby further improving the safety of the cooking utensil. In other embodiments, the cover opening confirmation key 30 can include both the fingerprint key and the cover opening operation part on the panel 11.

[0063] like Fig.15 and Fig.16 As shown, in the second embodiment, the cover opening member 20 includes a handle 23, and the fingerprint key is arranged on the handle 23. When the user places the finger on the fingerprint key and the verification is successful, the handle 23 can be immediately turned to open the cover.
