Description

Cooking utensil

Technical Field

The present invention relates to a cooking appliance.

Background

The existing cooking appliances such as electric cookers and the like are generally provided with a safety cover opening system for carrying out safety control on the cover opening operation. Specifically, the upper cover of the electric cooker is provided with a steam valve assembly which can be opened or closed or can be detached relative to the upper cover, and if a user opens the upper cover under the condition that the steam valve assembly is not installed in place, steam loss or other safety accidents can be caused. Therefore, it is undesirable that the upper cover can be opened without the steam valve assembly being installed in place. Thereby, a safe opening system is provided. When the steam valve assembly is not installed in place, the safety uncovering system is opened, the safety bolt is drawn out to be abutted against the uncovering operating device, and therefore the uncovering operating device is locked. In this case, the user cannot open the lid. When the steam valve component is installed in place, the safety uncovering system is closed, and the safety bolt is reset to release the butt joint with the uncovering operation device, so that the uncovering operation device is unlocked. In this way, the user can perform the opening operation. At present, a safety cover opening system generally uses a connecting rod structure and a return spring to cooperate so as to realize the extraction and the return of a safety bolt. For example, when the steam valve assembly is not installed in place, the steam valve assembly and the connecting rod structure are loosened, and the connecting rod structure is reset under the action of the reset spring so as to draw out the safety bolt to complete locking; when the steam valve component is installed in place, the steam valve component and the connecting rod structure act to push the connecting rod structure, and the safety bolt resets under the action of the reset spring, so that locking is released.

However, the above-mentioned safety cover opening system depends on a mechanical link structure and a return spring structure, and if the link structure cannot be linked normally or the return spring cannot be reset normally, the safety cover opening system cannot be opened normally. Therefore, a system for intelligently controlling the safe opening of the cover is needed.

SUMMERY OF THE UTILITY MODEL

In the summary section a series of concepts in a simplified form is introduced, which will be described in further detail in the detailed description section. The inventive content of the present invention is not intended to define key features or essential features of the claimed solution, nor is it intended to be used to limit the scope of the claimed solution.

In order to solve at least part of the above problems, the present invention provides a cooking appliance, characterized by comprising: a pot body; a lid body which is openably and closably provided to the pot body and forms a cooking space between the lid body and the pot body, the lid body being provided with an opening communicating with the cooking space and a steam valve assembly openably and closably mounted to the opening; the opening operation device is arranged on the cooker body and can be clamped with the cover body so as to operate the cooker body to be disengaged from the cover body; a safety lock device provided on the lid body, the safety lock device having an activated state and a deactivated state, the safety lock device abutting against the lid opening operation device when the safety lock device is in the activated state, and the safety lock device releasing the abutment against the lid opening operation device when the safety lock device is in the deactivated state; the detection device is arranged near the opening to detect whether the steam valve assembly covers the opening; and the control device is arranged on the cover body and is respectively and electrically connected with the safety lock device and the detection device.

According to the cooking appliance, the safe opening of the cooking appliance can be intelligently controlled. When the steam valve component is not installed in place, namely the steam valve component is not covered on the cover body, the safety lock device is started to abut against the cover opening operation device, so that the cover opening operation device cannot be operated, the cover body cannot be disengaged from the cooker body, and a user cannot open the cover. When the steam valve component is installed in place, namely the steam valve component covers the cover body, the safety lock device is closed to release the butt joint with the cover opening operation device, so that the cover opening operation device can be operated, the cover body is released from the clamping with the cooker body, and a user can open the cover. Therefore, the cover opening operation can be controlled through the intelligent safety lock device, and the steam loss or other safety accidents caused by misoperation of a user are avoided.

Preferably, the safety lock device includes a latch, the latch is retractable with respect to the lid and has a first position inserted into the pot body and a second position withdrawn from the pot body, when the safety lock device is in an activated state, the latch is located in the first position, when the safety lock device is in a closed state, the latch is located in the second position, and when the latch is located in the first position, the latch abuts against the lid opening operation device, so that the lid opening operation device maintains a state of being engaged with the lid. Therefore, when the safety lock device is started, the bolt is inserted into the cooker body to be abutted against the opening operation device, so that the opening operation device cannot be operated, the cover body cannot be disengaged from the cooker body, and the user cannot open the cover. When the safety lock device is closed, the bolt withdraws from the cooker body to release the butt with the cover opening operation device, so that the cover opening operation device can be operated, the cover body is released from the clamping with the cooker body, and a user can open the cover. Thus, the control of the opening operation can be realized by a simple safety lock structure.

Preferably, when the steam valve assembly covers the opening, the control device controls the safety lock device to be closed so that the bolt moves to the second position; when the steam valve component is not covered on the opening, the control device controls the safety lock device to be opened so that the bolt moves to the first position. Therefore, the opening and closing of the safety lock device can be controlled according to whether the steam valve assembly is installed in place, namely the insertion or the withdrawal of the bolt into or out of the cooker body is controlled.

Preferably, the safety lock device further comprises an electromagnet electrically connected to the control device and to the bolt, the electromagnet being operable to move the bolt to the first position when the safety lock device is in the activated state; when the safety lock device is in a closed state, the electromagnet acts to move the bolt to the second position. Thus, the plug can be inserted into or withdrawn from the cooker body by the electromagnet.

Preferably, the control device is configured to control the electromagnet to act according to the detection result of the detection device. Therefore, the electromagnet action can be intelligently controlled according to the detection result of the detection device.

Preferably, the lid opening operation device includes a lid opening button and a hook, the lid opening button is disposed on the surface of the pot body and can retract into the inner side of the pot body relative to the surface of the pot body, the hook can rotate relative to the pot body and can be interlocked with the lid opening button, the hook protrudes from the pot body toward the lid body and is engaged with the lid body in a state where the lid body is covered with the pot body, and the lid opening button pushes the hook to rotate the hook when the lid opening button retracts into the inner side of the pot body, so that the engagement of the hook and the lid body is released. Therefore, the user can operate the surface of the pot body, and the clasp is pushed by pressing the cover opening button so as to rotate relative to the pot body and release the clamping with the pot body. Thus, the opening operation can be more convenient.

Preferably, when the pin is located at the first position, the pin abuts against the clasp to prevent the clasp from rotating relative to the pot body. Therefore, the clasp cannot rotate relative to the pot body through the abutting of the latch and the clasp, and the cover opening button cannot be pressed down. Thus, the user cannot operate the lid opening button, and the lid opening operation cannot be performed.

Preferably, the cooker body is provided with a receptacle corresponding to the pin, and the pin is insertable into the receptacle to abut against the clasp. Therefore, the plug can be guided by the plug hole, so that the plug can be accurately moved to the position abutted to the clasp. In this way, the safety lock device can be reliably activated, and the object of disabling the lid opening operation device can be achieved.

Preferably, the control device is configured to control the activation state and the deactivation state of the security lock device according to the detection result of the detection device. Thereby, the security lock device can be intelligently controlled.

Preferably, when the steam valve assembly covers the opening, the control device controls the safety lock device to close the safety lock device; when the steam valve assembly does not cover the opening, the control device controls the safety lock device to enable the safety lock device to be started. Therefore, the starting and closing of the safety lock device can be intelligently controlled by detecting whether the steam valve assembly is installed in place, namely whether the steam valve assembly covers the opening of the cover body.

In the present embodiment, the cooking appliance 1 further includes a lid opening operation device 300, a safety lock device 400, a detection device 500, and a control device 600.

First, the structure of the cooking appliance 1 will be described in detail.

As shown in fig. 2 and 3, the cover 100 is provided with an opening 101 communicating with the cooking space and a steam valve assembly 102 openably and closably mounted to the opening 101. The steam valve assembly 102 is openably and closably connected to the cover 100 with respect to the opening 101. Fig. 2 is a sectional view showing a state where the steam valve assembly 102 is not mounted in place, in which the steam valve assembly 102 is in an open state with respect to the opening 101. Fig. 3 is a sectional view showing a state where the steam valve assembly 102 is mounted in place, in which the steam valve assembly 102 is in a covering state with respect to the opening 101.

The cover 100 is further provided with a detection device 500 for detecting whether the steam valve assembly 102 covers the opening 101. Preferably, a detection device 500 is provided near opening 101 to facilitate detecting whether steam valve assembly 102 is installed in place. The detection device 500 may be a sensor.

As shown in fig. 1 and 5, the pot body 200 is provided with a lid opening operation device 300, and the lid opening operation device 300 is operated by a user to open the lid body 100, that is, to release the engagement state of the lid body 100 and the pot body 200. Specifically, in the present embodiment, the door opening operation device 300 includes a door opening button 301 and a clasp 302. The open-cover button 301 is provided on the side surface of the pot body 200, and is retractable toward the inside of the pot body 200 with respect to the side surface of the pot body 200. The hook 302 is rotatable with respect to the pot body 200 and is interlocked with the lid opening button 301. When the lid body 100 is covered with the pot body 200, the hooks 302 protrude from the pot body 200 toward the lid body 100 and engage with the lid body 100, so that the lid body 100 is kept in a state of covering the pot body 200. When the user presses the lid opening button 301, the lid opening button retracts toward the inside of the pot body 200, and pushes the hook 302, so that the hook 302 rotates in a direction away from the lid body 100, thereby releasing the engagement with the lid body 100.

As shown in fig. 2, 3 and 4, the lid body 100 is further provided with a safety lock device 400 which can lock the lid opening operation device 300 so that the lid opening operation device 300 cannot be operated, thereby keeping the lid body 100 in a state of being engaged with the pot body 200; the lid opening operation device 300 may be unlocked to allow the lid opening operation device 300 to be operated, so that the lid body 100 is released from the engagement with the pot body 200. The safety lock device 400 has an activated state and a closed state, and when the safety lock device 400 is in the activated state, the safety lock device 400 abuts against the lid opening operation device 300 to lock the lid opening operation device 300; when the security lock device 400 is in the closed state, the security lock device 400 comes out of abutment with the lid opening operation device 300 to unlock the lid opening operation device 300. Specifically, the safety lock device 400 may include a latch 401, the latch 401 being retractable with respect to the lid body 100 and having a first position of being inserted into the pot body 200 and a second position of being withdrawn from the pot body 200, that is, the latch 401 may be projected from the lid body 100 to reach the first position of being inserted into the pot body 200 and may be retracted back to the lid body 100 to reach the second position of being withdrawn from the pot body 200.

When the safety lock device 400 is in the activated state, the latch 401 extends from the lid body 100 and is located at the first position, and abuts against the lid opening operation device 300, so that the lid opening operation device 300 is kept engaged with the lid body 100. Preferably, when the safety lock device 400 is in the activated state, the latch 401 extends from the lid body 100 to the first position inserted into the pot body 200, and abuts against the hook 302 of the lid opening operation device 300 to prevent the hook 302 from rotating with respect to the pot body 200. Thus, even if the user presses the lid opening button 301, the hook 302 cannot be pushed to release the engagement between the hook 302 and the lid body 100, and thus the lid opening operation device 300 cannot be locked by the lid opening operation.

When the security lock device 400 is in the closed state, the latch 401 is retracted back to the lid body 100 and positioned at the second position, and the contact with the lid opening operation device 300 is released, so that the lid opening operation device 300 is released from the engagement with the lid body 100. Preferably, when the safety lock device 400 is in the closed state, the latch 401 is retracted back to the lid body 100 to reach the second position where it is retracted from the pot body 200, thereby releasing the abutment with the hook 302 of the lid opening operation device 300 so that the hook 302 can rotate relative to the pot body 200. In this way, when the user presses the lid opening button 301, the lid opening button 301 pushes the hook 302 to rotate the hook 302, thereby releasing the engagement between the hook 302 and the lid body 100 and further releasing the locking of the lid opening operation device 300. At this time, the cover 100 may be opened by operating the cover opening operating device 300.

Preferably, a receptacle 303 corresponding to the pin 401 may be provided in the pot body 200 so that the pin 401 can be inserted into the receptacle 303 to abut against the hook 302.

The cover 100 is further provided with a control device 600, and the control device 600 is electrically connected to the safety lock device 400 and the detection device 500, respectively, to control the activation and the deactivation of the safety lock device 400 according to the detection result of the detection device 500. Specifically, when the detection device 500 detects that the steam valve assembly 102 is not installed in place, the control device 600 controls the safety lock device 400 to open, so that the latch 401 extends from the lid body 100 to reach the first position inserted into the cooker body 200, and abuts against the clasp 302 of the lid opening operation device 300, thereby completing the locking of the lid opening operation device 300. When the detection device 500 detects that the steam valve assembly 102 is installed in place, the control device 600 controls the safety lock device 400 to close, so that the latch 401 retracts back to the cover body 100 to reach the second position of exiting the cooker body 200, thereby releasing the contact with the hook 302 of the lid opening operation device 300 and releasing the locking of the lid opening operation device 300.

In this embodiment, the security lock device 400 preferably further comprises an electromagnet 402, the electromagnet 402 being electrically connected to the control device 600 and to the bolt 401 to move the bolt 401. Specifically, when the safety lock device 400 is in the activated state, the electromagnet 402 is actuated to move the bolt 401 to the first position; when the security lock arrangement 400 is in the closed state, the electromagnet 402 is actuated to move the bolt 401 to the second position.

Next, a flow of the control device 600 controlling the security lock device 400 will be described with reference to fig. 6.

If the steam valve assembly 102 does not cover the opening 101, the detection device 500 detects that the steam valve assembly 102 is not installed in place, and sends a signal a1 to the control device 600. Then, the control device 600 sends a signal B1 for unlocking the safety lock device 400 to the electromagnet 402, and the electromagnet 402 operates to extend the latch 401 from the lid body 100 to the first position where it is inserted into the pot body 200, and comes into contact with the hook 302 of the lid opening operation device 300, and at this time, the hook 302 cannot rotate, and even if the user presses the lid opening button 301, the user cannot push the hook 302 to release the engagement between the hook 302 and the lid body 100, and thus the lid opening operation device 300 cannot be unlocked and locked.

If the steam valve assembly 102 covers the opening 101, the detection device 500 detects that the steam valve assembly 102 is installed in place, and sends a signal a2 to the control device 600. Then, the control device 600 sends a signal B1 for closing the safety lock device 400 to the electromagnet 402, the electromagnet 402 operates to retract the latch 401 back to the lid body 100 to reach the second position for exiting the pot body 200, and the contact with the hook 302 of the lid opening operation device 300 is released, at this time, when the user presses the lid opening button 301, the lid opening button 301 pushes the hook 302 to rotate the hook 302, so that the engagement between the hook 302 and the lid body 100 is released, and the locking of the lid opening operation device 300 is released. At this time, the cover 100 may be opened by operating the cover opening operating device 300.
