Description

Technical Field

[0001] The invention relates to a pressure cooking device, a working method and a storage medium. Background Art

[0002] Pressure cooking devices such as pressure cookers and electric pressure cookers are widely used in life. Pressure cooking devices are usually equipped with a float and a stopper structure that cooperates with the float. When the pressure in the cooking chamber exceeds a certain pressure value, the float floats up, thereby driving the stopper structure to act. The stopper structure restricts the lid of the cooking device from opening, thereby playing a protective role. When the pressure in the cooking chamber drops to a lower pressure, the float will fall down by itself, and the stopper structure will act accordingly, thereby releasing the restriction on the lid.

[0003] For example, the Chinese utility model patent "Cover assembly and cooking utensil with the same" with authorization announcement number CN219331329U (application number 202320418450.7) discloses a cover assembly that is provided with a float valve and a lock ring that can float up and down, and a stop plate is provided on the lock ring; wherein, when the lock ring is in the unlocked position, the float valve and the stop plate are misaligned, and when the lock ring is in the locked position, the float valve can float upward and cooperate with the stop plate limit to limit the rotation of the lock ring. However, similar cooking utensils with float valves are inevitably stuck due to dirt blockage or other reasons during use, in which case the float cannot float normally. On the one hand, the user cannot find the situation that the float is stuck in time if he does not pay attention to observation, or mistakenly thinks that there is a cooking failure if he finds it. On the other hand, if the user manually presses the float when he finds that the float is stuck, there is a safety hazard. Summary of the invention

[0045] The present invention is further described in detail below with reference to the accompanying drawings.

[0046] like Figures 1 to 5As shown, the pressure cooking device in this embodiment includes a pot body 1, a cover body 2, a float 3, a first driving mechanism 4, and a control module 5, wherein the control module 5 is connected to the first driving mechanism 4 by electrical signals, thereby controlling the first driving mechanism 4 to work.

[0047] The shape of the pot body 1 is specifically set according to needs. Generally, the pot body 1 is open upward and has a cooking cavity for placing food. The cover body 2 matches the opening of the pot body 1 and can be opened and closed and is arranged on the pot body 1. In order to facilitate the opening and closing operation of the cover body 2 relative to the pot body 1, the pot body 1 in this embodiment is covered on the pot body 1 in a rotating clamping manner, that is, the pot body 1 and the cover body 2 matching structure of the pressure cooker in the prior art can be adopted.

[0048] The float 3 is arranged on the cover 2 so as to float up and down. In addition, the pressure cooking device of this embodiment is provided with a stop mechanism cooperating with the float 3, and the specific structure of the stop mechanism can adopt various stop structures in the prior art. Then, after the cover 2 is fixed on the pot body 1, when the float 3 floats up, the float 3 cooperates with the stop mechanism, and then the cover 2 is locked on the pot body 1, which can prevent the cover 2 from opening. When the float 3 sinks, the float 3 is unlocked from the stop mechanism, and then the cover 2 can rotate and separate from the pot body 1.

[0049] The first driving mechanism 4 is arranged on the cover 2 and located on one side of the float 3. The first driving mechanism 4 can act on the float 3 to drive the float 3 to shake. Specifically, the first driving mechanism 4 in this embodiment adopts an electric valve. In this embodiment, in order to facilitate the shaking drive of the float 3 and avoid the influence on the normal operation of the float 3 when the float 3 is not stuck, the float 3 adopts a metal part, and the driving end of the first driving mechanism 4 is provided with a magnet 41. The suction force of the magnet 41 on the float 3 is less than the pressure on the float 3 when the float 3 floats up. When the float 3 needs to be shaken, the control module 5 first drives the driving end of the first driving mechanism 4 to drive the magnet 41 close to the float 3, and then the magnet 41 and the float 3 are attracted, and then the control module 5 controls the first driving mechanism 4 to move back and forth, and then drives the float 3 to shake back and forth. When the float 3 is stuck due to dirt or other factors and cannot float up, based on the shaking of the float 3, the factors that jam the float 3 can be eliminated, and then the float 3 floats up normally, and the corresponding pressure cooking device can also work normally.

[0050] In order to effectively determine whether the float 3 is stuck, it is necessary to detect the position of the float 3 in the up and down direction. In this embodiment, in order to facilitate the detection of the floating state of the float 3, a distance sensor 6 connected to the control module 5 by electrical signals is also included, and the detection part of the distance sensor 6 is located above the float 3. The specific setting position of the distance sensor 6 is specifically set based on the specific structure of the pressure cooking device. For example, the distance sensor 6 can be set on the cover 2 through a bracket so that the detection part of the distance sensor 6 is located above the float 3. In addition, based on the structure of the box 7 described below, the distance sensor 6 can also be directly installed on the lower surface of the top wall of the box 7 so that the detection part of the distance sensor 6 is located above the float 3. The distance sensor 6 detects the distance between the float 3 and the float 3 from above the float 3. In the working state where the float 3 needs to float, if it is detected that the distance between the float 3 and the float 3 is greater than the set floating distance, it can be determined that the float 3 does not float normally. The distance sensor 6 can adopt various devices that can realize distance detection in the prior art.

[0051] In order to facilitate the diversification of the use positions of the pressure cooking device and improve the safety of the pressure cooking device when in use, the pressure cooking device in this embodiment also includes a box body 7, the pot body 1 and the cover body 2 are arranged in the box body 7, and the distance sensor 6 is arranged in the box body 7. Based on the structure of the box body 7, the pressure cooking device can be directly placed on the table for use, and can also be embedded for use, saving table space. In addition, based on the protection of the box body 7, the safety of users using the pressure cooking device can be improved.

[0052] In order to facilitate automatic and rapid exhaust, an electric push rod 8 connected to the control module 5 by electrical signals is also provided above the float 3 in the box 7. When rapid exhaust is required, the user only needs to send a rapid exhaust instruction to the control module 5, and the control module 5 can control the electric push rod 8 to move downward and act on the float 3, and the electric push rod 8 presses down the float 3 to achieve automatic exhaust. The user does not need to press down the float 3 by himself, making the rapid exhaust operation safer and more intelligent.

[0053] In order to save space in the box 7 , the electric push rod 8 in this embodiment is fixed on the distance sensor 6 , and the fixing position of the electric push rod 8 does not block the detection part of the distance sensor 6 .

[0054] In order to facilitate embedded installation and user operation, the box body 7 in this embodiment includes a box body 71 opened forward and a drawer 72 arranged in the box body 71 in a forward and backward push-pull manner, and the pot body 1 is arranged on a drawer board 721 of the drawer 72. Of course, as needed, a box body 71 opened upward and a structure of upper and lower flip covers can be adopted.

[0055] In order to improve the safety during operation, an electric door lock 70 is provided between the drawer 72 and the box body 71. The electric door lock 70 can adopt various electric door locks 70 in the prior art, such as the electric door lock 70 structure in appliances such as dishwashers, steamers, and ovens. The electric door lock 70 is connected to the control module 5 by electrical signals. The control module 5 controls the electric door lock 70 to lock and unlock based on the working stage and working state of the pressure cooking device.

[0056] In order to facilitate the user to open and close the cover 2 on the pot body 1 without opening the drawer 72, and to improve the safety of use, the cover 2 is rotatably connected to the pot body 1. A lever 9 is provided on the door panel 722 of the drawer 72, and one end of the lever 9 located inside the box 7 is abutted against the periphery of the pot body 1. A strip hole 7221 for swinging the lever 9 is horizontally provided on the door panel 722 corresponding to the position where the lever 9 is provided. In this way, the user can hold the part of the lever 9 exposed outside the door panel 722, and then move the lever 9 left and right within the range of the strip hole 7221, so that the lever 9 moves the cover 2 to achieve the connection and opening of the cover 2 on the pot body 1.

[0057] In order to avoid the operation of the cover body 2 under the high-pressure working state in the pot body 1 and improve the safety of use, a second driving mechanism 100 and a stop rod 101 connected to the second driving mechanism 100 are provided on the inner wall of the door panel 722 of the drawer 72. The second driving mechanism 100 can drive the stop rod 101 to move up and down to stop the lever 9 and release the stop of the lever 9. The second driving mechanism 100 in this embodiment can adopt various driving structures that can realize up and down driving in the prior art. The second driving mechanism 100 is connected to the control module 5 by electrical signals. In this way, when the pressure cooking device is working under high pressure, the control module 5 can control the second driving mechanism 100 to move, thereby driving the stop rod 101 to move up and limit the lever 9. The lever 9 cannot swing due to the restriction of the stop rod 101, which can effectively avoid the safety hazards caused by the operation of the cover body 2 under high-pressure working state. When the pressure cooking device is not working or working in a non-high pressure state, the control module 5 controls the second driving mechanism 100 to drive the stop rod 101 to the initial position. At this time, the stop rod 101 is in a position that does not restrict the lever 9, and the lever 9 can swing left and right based on the operation.

[0058] The working method of the aforementioned pressure cooking device is as follows.

[0059] When the user uses the pressure cooking device to cook, he places the food in the pot body 1, snaps the cover body 2 onto the pot body 1, opens the drawer 72, and places the pot body 1 at a specific position on the drawer. Then, the drawer 72 is pushed backward, so that the door panel 722 of the drawer 72 and the box body 7 are in a closed state.

[0060] The control module 5 controls the pressure cooking device to start working. After the pressure cooking device starts working, the working parameters of the pressure cooking device are detected and obtained. When the working parameters reach a set threshold, it is detected whether the float 3 floats up.

[0061] The purpose of detecting the working parameters is to determine whether the working condition that the float 3 needs to float up is reached. In this embodiment, any one of the following two methods can be used to determine the timing of detecting whether the float 3 floats up. The first is: the working parameter of the pressure cooking device obtained by detection is the energy consumption of the pressure cooking device, and the corresponding set threshold is the energy consumption threshold, that is, the timing of determining whether the float 3 floats up is based on the energy consumption of the pressure cooking device. Usually, heating is required for cooking, and the energy consumption of the pressure cooking device can be determined by detecting and calculating the heating power consumption. The other is: the working parameter of the pressure cooking device obtained by detection is the pressure in the pot body 1, and the corresponding set threshold is the pressure threshold, that is, the timing of determining whether the float 3 floats up is based on the pressure in the pot body 1.

[0062] In this embodiment, the distance signal detected by the distance sensor 6 is used to determine whether the float 3 floats up when it needs to float up. If it is detected that the float 3 floats up normally, cooking is performed normally.

[0063] If it is detected that the float 3 has not floated up, the first driving mechanism 4 is controlled to drive the float 3 to shake, so as to eliminate the situation that the float 3 is stuck due to dirt or other factors. After the factors that cause the float 3 to be stuck are eliminated due to the shaking of the float 3, the float 3 can automatically resume floating. However, it cannot avoid the situation that the float 3 still cannot float up normally based on the shaking of the float 3. Based on this, in this embodiment, when the first driving mechanism 4 is controlled to drive the float 3 to shake, the time for the first driving mechanism 4 to drive the float 3 to shake is counted at the same time, and whether the float 3 floats up is detected in real time. If the timing reaches the set time threshold and the float 3 still does not float up, the pressure cooking device is controlled to stop working, and the user is reminded to check whether the cover body 2 is installed in place on the pot body 1, and / or the user is reminded to detect and clean the dirt at the position of the float 3.

[0064] In order to improve the safety during high-pressure cooking, when the float 3 is detected to float up, the electric door lock 70 is controlled to lock the drawer 72 and the box body 71, so as to prevent the user from opening the drawer 72 when the pressure cooking device is working under high pressure, thereby ensuring the safety of use. At the same time, in order to avoid the misoperation of the cover 2 during high-pressure cooking and improve the safety, when the float 3 is detected to float up, the second driving mechanism 100 is controlled to drive the stop rod 101 to move and stop the lever 9, so that the lever 9 is in a stopped state. If the user operates the lever 9 in time, the lever 9 cannot swing due to the restriction of the stop rod 101, and the cover 2 cannot be opened accordingly, thereby ensuring the cooking safety during high-pressure cooking.

[0065] In addition, after the pressure cooking device finishes cooking, the electric push rod 8 is controlled to press the float 3 down to exhaust according to the obtained quick exhaust command signal. When the exhaust reaches the set low pressure, the float 3 will fall. After the pressure cooking device finishes cooking, if the quick exhaust command signal is not obtained, the float 3 will naturally fall based on natural exhaust until the exhaust reaches the set low pressure. After the distance sensor 6 detects that the float 3 has fallen, the control module 5 controls the second drive mechanism 100 to drive the stop rod 101 to move downward, releasing the stop restriction on the lever 9. At the same time, the control module 5 also controls the electric door lock 70 to unlock. The user can then open the drawer 72 and open the cover 2.

[0066] The pressure cooking device of the present invention is provided with a first driving mechanism 4 that can drive the float 3 to shake. Based on this, when the float 3 is stuck due to dirt or other reasons during the cooking process, the float 3 can be shaken by the first driving mechanism 4 to restore the float 3 to a floating state, and then based on the cooperation of the stop structure of the float 3 and the cover 2 in the prior art, the safety of the high-pressure cooking process is ensured. The pressure cooking device can automatically restore the float 3 to a normal state when the float 3 is stuck, making the pressure cooking device more intelligent and safer.

[0067] The working method of the pressure cooking device in the present invention can timely detect the situation that the float 3 does not float normally based on its working parameters and the detection of the floating state of the float 3, and then automatically restore the float 3 to the normal floating use state, thereby improving the safety of use, so that the pressure cooking device using the working method has a low failure rate and a good user experience.

[0068] The present invention also provides a computer-readable storage medium, comprising a computer program. When the computer program is run on a computer, the computer is enabled to execute the aforementioned working method.
