In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

The utility model provides a cooking utensil. According to the utility model discloses a cooking utensil can be for electric rice cooker, electric pressure cooker or other cooking utensil, and according to the utility model discloses a cooking utensil except having the function of cooking rice, can also have various functions such as cooking congee, a kind of deep pot hot water, fried dish. The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1, the cooking appliance 1 according to the present invention may include a pot body 40 and a lid body 10. The pot body 40 may be substantially configured in a rounded rectangular parallelepiped shape, and an inner pot 41 is provided inside thereof. The inner pot 41 may be configured to be removably disposed in the pot body 40. For example, in one embodiment, the pot body 40 may be provided with a cylindrical inner pot receiving portion, and the inner pot 41 may be freely put into or taken out of the inner pot receiving portion. The removable arrangement allows the user to easily remove the inner pot 41 for cleaning. Of course, in other embodiments, the inner pot 41 may be fixedly provided in the pot body 40 in a non-removable manner. The pot body 40 is also usually provided therein with a heating means for heating the inner pot 41.

As shown in fig. 1, the lid body 10 is provided to the pot body 40 in a manner openable and closable. Therefore, the lid body 10 generally has a shape conforming to the shape of the pot body 40, so that the pot body 40 can be easily covered. In the present embodiment, the lid body 10 may be pivotably connected to the pot body 40 by a pivot shaft (not shown). The pivot axis defines a pivot axis AX as shown in fig. 2. When the lid body 10 is opened with respect to the pot body 40, the opening of the inner pot 41 in the pot body 40 is exposed, and the user can add food materials to the inner pot 41 or take cooked food out of the inner pot 41. When the lid body 10 is closed on the pot body 40, it covers the inner pot 41 and forms a cooking space with the inner pot 41. A sealing member is further provided between the cover body 10 and the inner pot 41 to maintain a good sealing property of the cooking space.

According to the utility model discloses a cooking utensil 1 still is provided with steam generator. As shown in fig. 2, a steam generating device 20 for generating steam for assisting cooking is provided in the cover 10. Accordingly, a first steam channel (not shown) is provided on the cover 10. In a state where the lid body 10 covers the pot body 40, the steam generating device 20 can communicate with the cooking space through the first steam passage so as to guide steam into the cooking space for assisting in cooking.

Taking an electric cooker as an example, the specific operation of the auxiliary cooking may be to introduce the steam generated by the steam generating device 20 into the cooking space during the cooking process, and heat the rice from above, so that the rice can be uniformly heated, and the heating efficiency is improved; or after the rice is cooked, the steam generated by the steam generating device 20 is introduced into the cooking space to keep the rice warm, fresh and moist, so that the rice can keep good taste.

Specifically, as shown in fig. 2, in the present embodiment, the steam generating device 20 includes two parts, namely, a steam generating component 21 and a steam sealing component 22.

The steam generating assembly 21 comprises a steam generating chamber 23 for containing water to be heated for generating steam. Preferably, in the present embodiment, the steam generating module 21 includes a water container, and the steam generating chamber 23 is formed by an inner receiving space of the water container. Thereby, the steam generating chamber 23 can be conveniently provided. Further, the water container may be configured to be removably disposed. The user can conveniently take out the water container for cleaning or replacement. Of course, the steam generating chamber 23 may also be configured in other ways, such as being configured as a cavity integrally formed with the cover 10.

Furthermore, the steam generating assembly 21 comprises heating means (not shown) for heating the water inside the steam generating chamber 23 to generate steam.

The steam sealing member 22 is connected to the cover 10 and can be opened and closed with respect to the steam generating chamber 23. When the steam sealing component 22 is in a closed state, the steam sealing component 22 covers the steam generating cavity 23. The steam containment assembly 22 is shown in an open state in fig. 2. The user can observe the water level and the degree of cleanliness (whether scale is present, etc.) in the steam generation chamber 23 by opening the steam sealing member 22, and then decide whether to perform operations such as adding water or cleaning the steam generation chamber 23.

In this embodiment, the steam enclosure assembly 22 may be configured in the form of a steam cover plate 25. The steam cover plate 25 may be connected to the lid body 10 by a pivot shaft (not shown) and can pivot about the pivot shaft between a closed position covering the steam generating chamber 23 and an open position leaving the steam generating chamber 23 open. The steam cover plate 25 is provided with a seal 26 at a position corresponding to the steam generating chamber 23 on the side facing the steam generating chamber 23. When the steam sealing assembly 22 is in a covering state, the sealing member 26 is clamped between the steam cover plate 25 and the edge of the steam generating chamber 23 to play a role in sealing and prevent steam leakage.

In order to guide the steam generated in the steam generating chamber into the cooking space in a state that the steam generating chamber is sealed by the sealing member 26, a second steam passage (not shown) is provided on the steam cover plate 25. The second steam channel has a second steam inlet 252 and a second steam outlet 253. It will be appreciated that the second steam inlet 252 is located within the sealing area of the seal 26 and the second steam outlet 253 is located outside the sealing area of the seal 26. When the steam enclosure assembly 22 is in a closed position, the second steam outlet 253 interfaces with a first steam inlet (not shown) of the first steam channel. Steam generated in the steam generating chamber can flow into the second steam channel through the second steam inlet 252, continue to flow, and enter the first steam channel through the second steam outlet 253 and the first steam inlet which are butted. And finally flows out of the first steam outlet (not shown) of the first steam passage into the cooking space under the cover 10.

As shown in fig. 3, the steam generating device 20 further comprises a first locking device 30. When the steam cover 25 is in the closed position, the first locking device 30 can lock the steam cover 25 in the closed position so that it cannot move to the open position, thereby maintaining the steam generating chamber 23 in a sealed state. Of course, the first locking device 30 can also release the locking of the steam cover 25 in response to a user's operation or in response to a signal from the control device, etc., so that it can move from the covering position to the opening position to open the steam generating chamber 23.

According to the utility model discloses a cooking utensil, if steam generation chamber 23 opens under the state that lid 10 was opened, then the water that wherein holds easily flows out. The water enters the lid body 10 or the pot body 40 to come into contact with the electric parts, easily causing a short circuit or damage. At this time, if the steam generator 20 is in operation or is just finished, the temperature of the water is high, and the user is easily scalded. Therefore, when the lid body 10 is opened, the first locking device 30 needs to be always locked to the steam cover 25 in the closed position. Even if there is a user operation or a signal to unlock the first lock device 30, the first lock device 30 cannot perform an unlocking operation.

To achieve the above operation, the cover 10 is provided with a first detecting means 50 for detecting the open/close state of the cover 10 with respect to the pot body 40. When the first detecting means 50 detects that the cover 10 is in the open state, the first locking means 30 always maintains the locking of the steam cover 25 in response to the detection result of the first detecting means 50 regardless of the user operation or signal for unlocking the first locking means 30. When the first detecting device 50 detects that the lid 10 is in the closed state, the first locking device 30 can release the locking of the steam cover 25 when receiving an unlocking user operation or signal, so that the steam cover 25 can move from the closed position to the open position under the action of the user operation or the cover opening assisting device, and the steam generating chamber 23 is opened.

Specifically, in one embodiment, as shown in fig. 3, the first detecting device 50 may be configured as an angle switch, such as a mercury switch, or the like, disposed on the cover 10, and can generate a change of two states of closing and opening according to the change of the angle of the cover 10, so as to detect the opening and closing state of the cover 10.

In other embodiments not shown in the drawings, the first detection means may also be configured as a microswitch or the like provided on the lid, and accordingly, the pot body is provided with the trigger portion. When the cover body is covered on the cooker body, the trigger part presses the microswitch, and when the cover body is opened, the trigger part does not press the microswitch any more. So that the micro switch can be changed into an open state and a closed state along with the opening and closing of the cover body. Alternatively, the microswitch may be provided on the pot body and the trigger part may be provided on the lid body.

In addition, it is also possible to provide a reed switch on one of the pot body or the lid body and a magnetic field generating means such as a magnet on the other. The open-close state of the cover body is detected through the state change of the magnetic reed switch under the action of the magnetic field. The reed switch and the magnetic field generating device are configured as a first detecting device.

Alternatively, the detection electrode may be provided on one of the pot body and the lid, and the metal member may be provided on the other. With the change of the opening and closing state of the cover body, the distance between the detection electrode and the metal piece is changed, and the detected capacitance value is changed along with the change of the opening and closing state of the cover body. Thus, the open/close state of the lid can be detected by the change in capacitance value. The detection electrode and the metal member are configured as a first detection device.

Of course, the first detection device may also have other configurations, which are not illustrated here.

Further, as shown in fig. 3 and 4, the first locking device 30 includes a detent 31, a detent 32, and an electrical actuator 33. Wherein, the bayonet lock 31 is movably arranged on one of the steam cover plate 25 and the cover body 10, and the detent lock 32 is arranged on the other. In the illustrated embodiment, detent 31 is provided on lid 10 and detent 32 is provided on steam cover 25. The structure of the steam cover plate 25 can thereby be simplified. In other embodiments, the detent can be provided on the steam cover plate and the detent can be provided on the lid.

The detent 32 is designed as a recessed cavity. When the steam cover 25 is in the closed position, the detent 31 can extend laterally into the detent 32, thereby locking the steam cover 25 in the closed position against opening. When the latch 31 is withdrawn from the detent 32, the steam cover 25 is free to open without obstruction. The position in which detent 31 extends into detent 32 can be referred to as the latched position, and the position in which detent 32 is withdrawn can be referred to as the unlatched position.

Of course, the detent can also be configured in the form of a projection extending outwardly from the steam cover plate. When the clamping pin is positioned at the locking position, the clamping pin is positioned above the protruding part to prevent the steam cover plate from being opened. And when the bayonet is removed from above the projection, the steam cover plate can be freely opened.

An electrical actuator 33 is connected to bayonet 31. Electrically actuated member 33 is configured to automatically move detent 31 from the locked position to the unlocked position when actuated, thereby releasing detent 31 from engagement with detent 32 and allowing steam cover 25 to be freely opened. Specifically, as shown in fig. 4, in the present embodiment, the electric actuator 33 is configured as an electromagnet having a movable shaft 34 capable of moving in its own axial direction. Bayonet 31 is connected to movable shaft 34. When the electromagnet is powered on to work, magnetic force is generated, the movable shaft 34 moves along the direction from left to right in fig. 4 under the action of the magnetic force, and meanwhile, the bayonet 31 is driven to move from the locking position to the unlocking position.

Preferably, an actuation button 37 may also be provided, as shown in fig. 5. The user may actuate the electrically actuated member 33 by activating the actuating button 37. In other words, the first locking means 30 can release the locking of the steam cover 25 in response to the user's operation of pressing the actuating button 37. Preferably, the actuating button 37 may be provided on the cover 10. Alternatively, the actuation of the electric actuator may be controlled in a voice-controlled manner without providing an actuation button.

Further, the electrical actuator 33 may be electrically connected with the first detection device 50. For example, the first detection device 50 can be connected in series to the supply circuit of the electrical actuation member 33. When the cover 10 is closed, the mercury switch or the micro switch configured as the first detection means 50 is in a closed state. When the user actuates the actuating button 37, the electrical actuator 33 can be energized to actuate, moving the latch 31 to the unlocked position to unlock the steam cover 25. When the cover 10 is opened, the mercury switch or the micro switch configured as the first detection means 50 is in an off state. At this point, even if the user touches the actuation button 37, the electric actuator 33 cannot be powered and thus cannot be actuated. Thus, bayonet 31 remains locked to steam cover 25 in the locked position so that it cannot be opened.

Of course, in another embodiment, the electric actuator and the first detection device can also be electrically connected to a control device (not shown) of the cooking utensil at the same time, and the control device determines whether to actuate the electric actuator according to the detection result of the first detection device, so as to realize that the locking of the steam cover plate can be released when the cover body is closed, and the locking of the steam cover plate can be maintained when the cover body is opened. In this embodiment, the first locking means simultaneously activates the electric actuator in response to a user's operation (e.g., touching an actuator button or sending voice control information) and a control signal from the control means to unlock the steam cover.

Preferably, as shown in fig. 4, the first locking device 30 further includes a reset member 35. Reset element 35 can apply a spring force directly or indirectly to bayonet 31 from the unlocked position toward the locked position to bias bayonet 31 toward the locked position.

In the present embodiment, the restoring element 35 is configured as a coil spring that is sleeved on the movable shaft 34 and is located at one end of the movable shaft 34 away from the bayonet 31. Therefore, restoring member 35 is configured to indirectly apply an elastic force to bayonet 31. When the electromagnet is powered on to work, the movable shaft 34 overcomes the elastic force of the spring under the action of magnetic force to drive the bayonet 31 to move from the locking position to the unlocking position. While the spring is compressed. When the electromagnet is not electrified, the magnetic force disappears, the spring is restored under the action of the elastic force of the spring, and the movable shaft 34 drives the bayonet 31 to move from the unlocking position to the locking position under the action of the elastic force. It will be appreciated that the reset element may also be configured as a pad of rubber, silicone, or the like.

Referring to fig. 6, in other embodiments, a restoring member 135 configured as a coil spring may also be disposed at an end of the movable shaft 134 near the latch 131. In this arrangement, when the detent 131 is moved by the movable shaft 134 to the unlocked position, the spring is stretched, rather than compressed. The spring indirectly applies a resilient force to the click pin 131 by being stretched by itself to bias it toward the locked position.

Referring to fig. 7, in other embodiments, the electric actuator may be further configured to include a drive motor 233 and a cam 234. The cam 234 is connected to the driving motor 233, and can be rotated by the driving motor 233. The cam 234 has a cam track including a low point M and a high point N. The click pin 231 abuts the cam 234 and is movable relative to the cam 234 along the cam locus with the rotation of the cam 234. Wherein the detent 231 is in the latched position when it abuts the low point M. And when detent 231 abuts high point N, it is in the unlocked position.

Preferably, the distance L between the low point M and the high point N of the cam track (i.e., the travel by which the detent 231 moves from the latched position to the unlatched position) is 1-15 mm. Further preferably, L may be 2-6 mm. For example, L may take the value of 1mm, 2mm, 4mm, 6mm, 10mm, 13mm, 15mm or any value within the above range depending on the size of the lid.

In the embodiment shown in fig. 7, the return element 235, which is embodied as a coil spring, acts directly on the detent 231. This is because cam 234 exerts a force on detent 231 during movement of detent 231 along the cam track from low point M to high point N, while cam 234 exerts no force on detent 231 during movement of detent 231 along the cam track from high point N to low point M. Thus, the reset 235 acts directly on the detent 231.

In the daily use, there is also a case where the lid body 10 is opened by the erroneous operation of the lid-opening button 61 while the steam cover 25 is still in the open position, and there is also a risk that water in the steam accommodating chamber 23 will spill. Therefore, as shown in fig. 3 and 4, the cooking appliance according to the present invention further includes a second detecting device 70 and a second locking device 60.

Wherein, the second detecting device 70 is used for detecting the opening and closing state of the steam cover plate 25. When the second detecting means 70 detects that the steam cover 25 is in the opened state, the second locking means 60 always maintains the lid body 10 in the closed state with respect to the pot body 40 in response to the detection result of the second detecting means 70 regardless of the user operation or signal. When the second detecting means 70 detects that the steam cover 25 is in the closed state, the second locking means 60 can unlock the lid 10 so that it can be opened with respect to the pot body 40.

The second sensing device 70 may have a similar configuration as the first sensing device 50 and will not be described in detail herein.

As shown in fig. 3, generally, the lid body 10 may be maintained in a covering state with respect to the pot body 40 in a hooking manner by a hook (not shown), and may be released from the hooking state by pressing the lid opening button 61 and automatically opened by the action of a lid opening assisting means (e.g., a torsion spring) attached to a pivot shaft of the lid body 10. The second locking device 60 can be configured in the form of a stop. When the second detecting means 70 detects that the steam cover 25 is opened, the stopper is located on the moving path of the lid-opening button 61, so that the steam cover cannot be pressed, i.e., the lid cannot be opened. When the second detecting means 70 detects that the steam cover 25 is closed, the stopper is moved away from the moving path of the lid-opening button 61, and the lid-opening button 61 can be pressed to open the lid body 10.

The limit stop can be embodied in particular in the form of a movable shaft of an electromagnet. The electromagnet is electrified to work in response to the second detection device 70 detecting that the steam cover 25 is opened, so that the movable shaft moves to the moving path of the cover opening button 61; and to remove the movable shaft from the moving path of the door-opening button 61 in response to the second sensing means 70 sensing the closing of the steam cover 25 and thus the power-off inoperative.

Of course, the second locking device 60 can also have a similar construction to the first locking device 30. And will not be described in detail herein.

According to the utility model discloses a cooking utensil can control locking and unblock of first locking device to the steam cover based on whether detection and the judgement that first detection device closed to the lid to the accident of the water in the steam generation chamber that unblock steam cover plate leads to is emptyd when avoiding the lid to open, has good security. The locking and unlocking of the cover body by the second locking device can be controlled based on the detection and judgment of whether the steam cover plate is covered by the second detection device, so that the accidental dumping of water in the steam generation cavity caused by opening the cover body by forgetting to cover the steam cover plate is avoided, and the safety is further improved. Furthermore, by configuring the first locking means to include an electric actuator, the linkage with other electric devices is facilitated, thereby facilitating automatic control of the cooking appliance.
