Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and more specifically relates to an electric pressure cooker with a safety locking cover protection device. Background Art

[0002] With the continuous improvement of living standards, electric pressure cookers have become an indispensable household appliance in people's daily lives. Most electric pressure cookers currently sold on the market are equipped with a safety locking structure. However, when in use, if the lid and the pot body are not properly buckled or the lid is misaligned, the menu function can still be activated and heating and cooking can be performed, which will cause certain safety hazards in the use of electric pressure cookers.

[0003] Although there are some technical settings that have been used to lock the lids of electric pressure cookers, they are inconvenient to use and lack intelligence. Utility Model Content

[0004] The utility model provides an electric pressure cooker with a safety locking cover protection device to overcome the above-mentioned deficiencies in the prior art.

[0005] In the technical solution, an electric pressure cooker with a safety lock cover protection device is provided, comprising an electric pressure cooker body, the electric pressure cooker body is provided with a controller for controlling the working state of the electric pressure cooker body and a safety lock cover protection device for sending a signal whether the controller is working, the safety lock cover protection device is electrically connected to the controller, and the safety lock cover protection device comprises a magnetic control switch for sending a signal whether the controller is working and a magnet component for triggering the magnetic control switch;

[0006] When the electric pressure cooker main body lock cover is in place, the magnet component and the magnetic control switch are offset from each other, and the magnetic control switch sends a working signal to the controller; otherwise, the magnetic control switch sends a stop working signal to the controller.

[0007] The utility model is provided with a controller for controlling the working state of the electric pressure cooker body and a safety cover lock protection device for sending a signal to the controller whether it is working, the safety cover lock protection device is electrically connected to the controller, and the safety cover lock protection device includes a magnetic control switch for sending a signal to the controller whether it is working and a magnet component for triggering the magnetic control switch; when the electric pressure cooker body is locked in place, the magnet component and the magnetic control switch are staggered, and the magnetic control switch sends a working signal to the controller; on the contrary, the magnetic control switch sends a stop working signal to the controller, so that when the electric pressure cooker body is powered on, when the cover is locked in place, the magnet component and the magnetic control switch are staggered, the magnet component can trigger the magnetic control switch to send a working signal to the controller, and the controller can start cooking according to the signal sent by the magnetic control switch. Since the magnet component and the magnetic control switch are staggered when the electric pressure cooker body is locked in place, double guarantee will occur only when the magnetic control switch sends a working signal to the controller, thereby improving the safety of the electric pressure cooker. In addition, the reason for not starting when the magnetic component is in contact with the magnetic control switch or facing each other is to avoid the magnetic field formed by the contact between the magnetic component and the magnetic control switch affecting the stability of the circuit of the electric pressure cooker. At the same time, since the lid of the electric pressure cooker body will jump up and down during the cooking process, the stability of the contact between the magnetic component and the magnetic control switch cannot be guaranteed. Therefore, the position of the magnet component and the magnetic control switch is set to be staggered as a state in which a working signal can be sent to the controller, which can effectively ensure the reliability and safety of the locking cover. Through the setting of the safety locking cover protection device, when the electric pressure cooker body has not completed the locking cover, when the power is on, the magnet component will not trigger the magnetic control switch to send a working signal to the controller. The controller does not receive the working signal sent by the magnetic control switch, and the cooking process cannot be started. Through this signal setting that the magnet component and the magnetic control switch are staggered when the electric pressure cooker body is in place when the locking cover is in place, the dangerous situation of the flying cover is avoided, and the safety, intelligence and convenience of the operation of the electric pressure cooker are improved.

[0008] Preferably, the main body of the electric pressure cooker includes a pot body and a pot cover that is rotatably buckled relative to the pot body, the magnet component is arranged on the pot cover, and the magnetic control switch is arranged on the corresponding position of the pot body; when the pot body and the pot cover are buckled in place, the magnetic control switch and the magnet component are staggered, and the magnetic control switch sends a working signal to the controller; otherwise, the magnetic control switch sends a stop working signal to the controller. By setting, when the pot body and the pot cover are buckled in place under power-on, the magnetic control switch and the magnet component are staggered, and the magnet component can trigger the magnetic control switch to send a working signal to the controller. Since the positions of the magnet component and the magnetic control switch are staggered when the pot body and the pot cover are buckled in place, the magnetic control switch sends a working signal to the controller in this double guarantee, avoiding the situation of flying cover and improving the safety of cooking in the electric pressure cooker. Since the magnetic control switch and the magnet component are not staggered, a magnetic field will be generated to affect the circuit inside the electric pressure cooker. Therefore, it is set that the magnetic control switch and the magnet component must be staggered, and the magnetic control switch sends a working signal to the controller, which can improve the stability of the entire working circuit inside the electric pressure cooker. This design does not select to send a working signal to the controller when the magnetic control switch contacts the magnet component, because it is unreasonable to set the controller to start when the magnetic control switch contacts the magnet component, because there is a magnetic field formed by the magnetic control switch and the magnet component, which causes the stability of the working circuit of the electric pressure cooker to deteriorate, and during the cooking process, the pot cover will float up and down, which will also affect the reliability of the contact and send out wrong signals. Therefore, it is necessary to ensure that the magnetic control switch and the magnet component are staggered in position to work, which can ensure the stability of the entire electric pressure cooker.

The pot cover is provided with a protrusion, the pot body is provided with a stroke groove for the pot cover to rotate relative to the pot body, and the protrusion is movably engaged with the stroke groove to facilitate the pot cover to quickly cover the pot body. At the same time, the stroke groove is provided to facilitate the pot cover and the pot body to be covered in place on the surface, but in order to prevent the accident of flying cover, the pot cover is rotated to allow the protrusion to move in the stroke groove until the magnet component and the magnetic control switch are misaligned, and then the magnetic control switch sends a signal to the controller, and the controller can start the cooking work according to the signal sent by the magnetic control switch; otherwise, the cooking work cannot be started. The mechanically arranged protrusion and stroke groove can allow the pot cover and the pot body to be quickly covered, thereby improving the convenience of covering. Then, when the pot cover and the pot body have been fastened but not yet in place, it is still necessary to rotate the pot cover so that the protrusion moves in the travel groove until the position of the magnet component and the magnetic control switch are offset, and then the magnetic control switch sends a working signal to the controller, so that the cooking program can be started, which greatly improves the reliability of the pot cover and the pot body being in place, avoids the situation of the lid flying off, and improves the safety of cooking. Preferably, the magnetic control switch is installed near the travel groove, and the magnet component is installed inside or near the protrusion. This is convenient for directly staggering the position of the magnet component and the magnetic control switch during the rotation of the pot cover, thereby improving the convenience of operation. Of course, it should be noted that this setting is not a restrictive provision, but only a preference.

[0010] Preferably, the pot cover includes an inner cover, the magnet component is arranged at the edge of the inner cover, and the pot cover is provided with a fixing component for reliably mounting the magnet component. The arrangement of the magnet component at the edge of the inner cover is to facilitate the magnet component to quickly face the magnetic control switch during the rotation of the pot cover to complete the corresponding operation.

[0011] Preferably, the fixing component includes a first pressing plate and a second pressing plate arranged on both sides of the magnet component. The first pressing plate and the second pressing plate arranged on both sides of the magnet component are arranged to facilitate the reliable installation of the magnet component. It should be noted that the arrangement of the first pressing plate and the second pressing plate is to provide a solution for fixing the magnet component, and is not the only fixing solution.

[0012] Preferably, the pot body is provided with a middle ring, and the magnetic control switch is arranged inside the middle ring. The magnetic control switch is arranged inside the middle ring to correspond to the installation position of the magnet component. It should be noted that the position where the magnetic control switch is arranged matches the set position of the magnet component. The magnetic control switch is arranged inside the middle ring and corresponds to the position where the magnet component is arranged on the edge of the inner cover. Their position setting is not unique, and they can be arranged at other relative positions.

[0013] Preferably, the pot body is provided with a second fixing component for fixing the magnetic control switch on the inner side of the middle ring, and the second fixing component is a threaded component. The pot body is provided with a second fixing component for fixing the magnetic control switch on the inner side of the middle ring in order to reliably fix the magnetic control switch. The second fixing component is provided as a threaded component in order to provide a fixing method, such as a snap-on method, a buckle or other fixing methods are also feasible, and no specific limitation is made here.

[0014] Preferably, the controller includes a control board and an interactive panel, and the magnetic control switch, the control board, and the interactive panel are electrically connected in sequence. The arrangement of the magnetic control switch, the control board, and the interactive panel being electrically connected in sequence is that when the pot body and the pot cover are buckled in place, the magnetic control switch is opposite to the magnet component, and when the power is on, the magnet component can trigger the magnetic control switch to send a working signal to the control board, and the circuit is now connected; then when the interactive panel receives the cooking instruction, it can send it to the control board to start the corresponding operation and cook. This arrangement is to improve safety and intelligence.

[0015] Preferably, the pot cover further comprises an outer cover and a steel cover, and the outer cover, inner cover and steel cover are installed in sequence to form the pot cover.

[0016] Preferably, the pot body comprises a shell, and the interactive panel is arranged on the shell. The interactive panel is arranged on the shell to facilitate the operation of the interactive panel and send cooking instructions.

The heat preservation cover is fixedly mounted in the outer shell, which can achieve heat preservation and at the same time protect the heat preservation cover through the outer shell to prevent the heat preservation cover from being damaged.

[0018] Compared with the prior art, the beneficial effects are:

Since the magnet component and the magnetic control switch are staggered when the electric pressure cooker body is locked in place, double guarantee will occur only when the magnetic control switch sends a working signal to the controller, thereby improving the safety of the electric pressure cooker. In addition, the reason for not starting when the magnetic component is in contact with the magnetic control switch or facing each other is to avoid the magnetic field formed by the contact between the magnetic component and the magnetic control switch affecting the stability of the circuit of the electric pressure cooker. At the same time, since the lid of the electric pressure cooker body will jump up and down during the cooking process, the stability of the contact between the magnetic component and the magnetic control switch cannot be guaranteed. Therefore, the position of the magnet component and the magnetic control switch is set to be staggered as a state in which a working signal can be sent to the controller, which can effectively ensure the reliability and safety of the locking cover. Through the setting of the safety locking cover protection device, when the electric pressure cooker body has not completed the locking cover, when the power is on, the magnet component will not trigger the magnetic control switch to send a working signal to the controller. The controller does not receive the working signal sent by the magnetic control switch, and the cooking process cannot be started. Through this signal setting that the magnet component and the magnetic control switch are staggered when the electric pressure cooker body is in place when the locking cover is in place, the dangerous situation of the flying cover is avoided, and the safety, intelligence and convenience of the operation of the electric pressure cooker are improved.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0030] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0031] Example

[0032] like Figures 1 to 8 An electric pressure cooker with a safety lock cover protection device, comprising an electric pressure cooker body 1, on which a controller 2 for controlling the working state of the electric pressure cooker body 1 and a safety lock cover protection device 3 for sending a signal to the controller 2 to indicate whether the electric pressure cooker body 1 is working are arranged, wherein the safety lock cover protection device 3 is electrically connected to the controller 2, and the safety lock cover protection device 3 comprises a magnetic control switch 31 for sending a signal to the controller 2 to indicate whether the electric pressure cooker body 1 is working and a magnet component 32 for triggering the magnetic control switch 31;

[0033] When the electric pressure cooker body 1 is locked in place, the magnet component 32 and the magnetic control switch 31 are offset from each other, and the magnetic control switch 31 sends a working signal to the controller 2; otherwise, the magnetic control switch 31 sends a stop working signal to the controller 2.

[0034] The electric pressure cooker body 1 includes a pot body 11 and a pot cover 12 that is rotatably buckled relative to the pot body 11, a magnet component 32 is arranged on the pot cover 12, and a magnetic control switch 31 is arranged at a corresponding position of the pot body 11; when the pot body 11 and the pot cover 12 are buckled in place, the magnetic control switch 31 and the magnet component 32 are staggered, and the magnetic control switch 31 sends a working signal to the controller 2. By setting, when the pot body and the pot cover are buckled in place under power-on, the magnetic control switch and the magnet component are staggered, and the magnet component can trigger the magnetic control switch to send a working signal to the controller. Since the magnet component and the magnetic control switch are staggered when the pot body and the pot cover are buckled in place, the double guarantee will cause the magnetic control switch to send a working signal to the controller, avoiding the situation of flying cover, and improving the safety of cooking in the electric pressure cooker. Since the magnetic control switch and the magnet component are not misaligned, a magnetic field will be generated to affect the circuit inside the electric pressure cooker. Therefore, the requirement is set that the magnetic control switch and the magnet component must be staggered, and the magnetic control switch sends a working signal to the controller, which can improve the stability of the entire internal working circuit of the electric pressure cooker. This design does not select the magnetic control switch to send a working signal to the controller when it contacts the magnet component, because it is unreasonable to set the controller to start when the magnetic control switch contacts the magnet component, because there is a magnetic field formed by the magnetic control switch and the magnet component, which causes the stability of the working circuit of the electric pressure cooker to deteriorate, and during the cooking process, the pot cover will float up and down, which will also affect the reliability of the contact and send out wrong signals. Therefore, it is selected to ensure that the magnetic control switch and the magnet component are staggered in order to work, which can ensure the stability of the entire electric pressure cooker.

[0035] In addition, the pot cover 12 is provided with a protrusion 124, and the pot body 11 is provided with a stroke groove 115 for the pot cover 12 to rotate relative to the pot body 11, and the protrusion 124 is movably engaged with the stroke groove 115. The pot cover 12 is provided with a protrusion 124, and the pot body 11 is provided with a stroke groove 115 for the pot cover to rotate relative to the pot body. The setting of the protrusion and the stroke groove is to facilitate the pot cover to be quickly covered with the pot body. At the same time, the stroke groove is set to facilitate the pot cover and the pot body to be covered in place from the surface, but in order to prevent the accident of flying cover, the pot cover is rotated to allow the protrusion to move in the stroke groove until the magnet part and the magnetic control switch are offset, and then the magnetic control switch sends a signal to the controller, and the controller can start the cooking work according to the signal sent by the magnetic control switch; otherwise, the cooking work cannot be started. The mechanically set protrusion and stroke groove can allow the pot cover and the pot body to be quickly covered, thereby improving the convenience of covering. Then, when the pot cover and the pot body have been fastened but not in place, it is still necessary to rotate the pot cover so that the protrusion moves in the stroke groove until the position of the magnet component and the magnetic control switch are offset, and then the magnetic control switch sends a working signal to the controller, so that the cooking program can be started, which greatly improves the reliability of the pot cover and the pot body being in place, avoids the situation of flying cover, and improves the safety of cooking. Preferably, the magnetic control switch is installed near the stroke groove, and the magnet component is installed inside or near the protrusion. This is convenient for directly staggering the position of the magnet component and the magnetic control switch during the rotation of the pot cover, thereby improving the convenience of operation. Of course, it should be noted that this setting is not a restrictive provision, but only a preferred one. Preferably, when the protrusion 124 of the pot cover 12 has been snapped into the stroke groove 113 of the pot body 11, but the cover is not in place, that is, the position of the magnet component 32 and the magnetic control switch 31 is not offset, the controller 2 can be prompted with an early warning device (such as a buzzer) when receiving the non-working signal. This setting is to facilitate the rapid detection of failure to fasten in place and improve safety.

[0036] Among them, the pot cover 12 includes an inner cover 121, and the magnet component 32 is arranged at the edge of the inner cover 121. The pot cover 12 is provided with a fixing component 13 for reliably installing the magnet component 32. The arrangement of the magnet component at the edge of the inner cover is to facilitate the magnet component to quickly face the magnetic control switch during the rotation of the pot cover to complete the corresponding operation. The pot cover is provided with a fixing component for reliably installing the magnet component in order to reliably install the magnet component. Of course, it should be noted that the arrangement of the magnet component at the edge of the inner cover is only to provide a way of installation. It should be noted that this is only preferred and not necessary.

[0037] In addition, the fixing component 13 includes a first pressing plate 131 and a second pressing plate 132 arranged on both sides of the magnet component 32. The first pressing plate and the second pressing plate are arranged on both sides of the magnet component to facilitate the reliable installation of the magnet component. It should be noted that the arrangement of the first pressing plate and the second pressing plate is to provide a solution for fixing the magnet component, and is not the only fixing solution. Figure 3 , Figure 8 As shown, the inner cover 121 is provided with a second groove 5 for installing the magnet component 32. The magnet component 32 is installed in the second groove 5. The magnet component 32 is pressed and fixed downward by the first pressing plate 131 and the second pressing plate 132. Then, the first pressing plate 131 and the second pressing plate 132 are fixed to the inner cover 121 through a threaded structure, so that the magnet component 32 is reliably fixed.

[0038] The pot body 11 is provided with a middle ring 111, and the magnetic control switch 31 is arranged inside the middle ring 111. The magnetic control switch is arranged inside the middle ring to correspond to the installation position of the magnet component. It should be noted that the position where the magnetic control switch is arranged matches the set position of the magnet component. The magnetic control switch is arranged inside the middle ring and corresponds to the position where the magnet component is arranged on the edge of the inner cover. This position setting is not unique, and it is also feasible for them to be arranged at other relative positions.

[0039] In addition, the pot body 11 is provided with a second fixing component 14 for fixing the magnetic control switch 31 on the inner side of the middle ring 111, and the second fixing component 14 is a threaded component. The pot body 11 is provided with a second fixing component for fixing the magnetic control switch on the inner side of the middle ring in order to reliably fix the magnetic control switch. The second fixing component is a threaded component in order to provide a fixing method, such as a snap-on method, a buckle or other fixing methods are also feasible, and no specific restrictions are made here. Figure 6 , Figure 7 As shown, the middle ring 111 is provided with a mounting portion 4 for mounting the magnetic control switch 31. The magnetic control switch 31 is installed in the mounting portion 4 and then fixed by the second fixing component 14, so that the magnetic control switch 31 is reliably fixed.

[0040] The controller 2 includes a control board 21 and an interactive panel 22, and the magnetic control switch 31, the control board 21, and the interactive panel 22 are electrically connected in sequence. The arrangement of the magnetic control switch, the control board, and the interactive panel being electrically connected in sequence is that when the pot body and the pot cover are buckled in place, the magnetic control switch is opposite to the magnet component, and when the power is on, the magnet component can trigger the magnetic control switch to send a working signal to the control board, and the circuit is now connected; then when the interactive panel receives the cooking instruction, it can send it to the control board to start the corresponding operation and cook. This arrangement is to improve safety and intelligence.

[0041] In addition, the pot cover 12 further includes an outer cover 122 and a steel cover 123 . The outer cover 122 , the inner cover 121 , and the steel cover 123 are installed in sequence to form the pot cover 12 .

[0042] The pot body 11 includes a shell 112, and the interactive panel 22 is arranged on the shell 112. The interactive panel is arranged on the shell to facilitate the operation of the interactive panel and send cooking instructions.

[0043] In addition, the pot body 11 also includes an inner pot 113 and a heat preservation cover 114. The inner pot 113 can be disassembled and placed in the heat preservation cover 114. The heat preservation cover 114 is fixedly installed in the outer shell 112, and the middle ring 111 is fixedly installed with the heat preservation cover 114. The inner pot can be disassembled and placed in the heat preservation cover to facilitate cleaning of the inner pot. The heat preservation cover is fixedly installed in the outer shell, which can not only achieve heat preservation, but also protect the heat preservation cover through the outer shell to prevent the heat preservation cover from being damaged.

[0044] The working principle of this embodiment is:

[0045] When working (that is, when powered on), when the pot cover 12 is not placed on the pot body middle ring 111, the magnetic control switch 31 is not interfered by the magnet component 32, and the control board 21 in the controller 2 and the various menu functions of the interactive panel 22 can work normally; when the pot cover 12 is placed in the pot body middle ring 111 position, and then the pot cover 12 is provided with a protrusion 124 and is engaged with the travel groove 113 of the pot body 11, but the pot cover 12 is not rotated to the lock cover limit position (closed in place), the magnetic control switch 31 will be interfered by the magnet 31, and the interactive panel 22 input command of the controller 2 is invalid, that is, the various menu functions are restricted and cannot work normally. The pot cover 12 must be rotated to the lock cover position to remove the interference of the magnetic control switch 31 and restore the interactive panel 22 input command to be valid, that is, the normal operation of various menu functions, ensuring the reliability of the safety lock cover.

[0046] It should be noted that the interference of the magnetic switch 31 here is to send a signal to the control board in the controller 2, and the control board decides whether to work according to the signal. The interactive panel only inputs corresponding commands to the control board, that is, working instructions.

[0047] When the pot cover 12 is not stamped on the pot body 11, the pot body 11 is equivalent to opening the lid, and the pot body 11 can work normally at this time, regardless of whether the pot cover is closed or not.

[0048] The control board in the controller 12 is generally a 51 single chip microcomputer or other CPU.

[0049] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
