Description

Technical Field

[0001] The utility model relates to the technical field of cooking appliances, and more specifically, to an integrated structure for high-pressure stop multi-detection and an electric pressure cooker. Background Art

[0002] Some existing cooking appliances, such as electric pressure cookers, are provided with a high-pressure stop device. That is, when the pressure inside the pot reaches a preset high pressure, the high-pressure stop device will prevent the user from opening the pot lid. Some existing cooking appliances are provided with a lid opening / closing device. The lid opening / closing device includes a movable swing rod, and the function of locking / unlocking the pot lid is realized by the displacement of the swing rod. The high-pressure stop device includes a stop rod. The stop rod has a rising position and a falling position according to the pressure inside the pot. When the pressure inside the pot reaches the preset high pressure (when there is pressure), the stop rod rises to the high position; when the pressure inside the pot is lower than the preset high pressure (when there is no pressure), the stop rod drops to the low position; it is necessary for the stop rod to be in the low position (i.e., no-pressure state) to open and close the lid to ensure the safety of people when using the pressure cooker.

[0003] In some existing cooking appliances with a high-pressure stop device, during normal use, due to differences in detection accuracy, cooking programs, and usage environments, the stop rod may not fall back under high pressure. At this time, if the swing rod of the opening / closing device accidentally operates in advance to open or close, it may cause damage to the corresponding driving components and the problem of inability to open the lid. In addition, to determine whether the lid opening / closing device is in place, magnetic induction technology is usually used. Due to the large required tolerance (the required variation between induction positions), incorrect induction judgments often occur in miniaturized products, resulting in product error reports and the problem that users cannot open the lid; the above two points are not conducive to the structural stability of the product and the user experience. Summary of the Utility Model

[0004] To solve at least one of the above problems, the present utility model provides an integrated structure for high-pressure stop and multiple detections, including: a pot lid assembly and an inner pot. The pot lid assembly includes an opening / closing lid device, and the opening / closing lid device includes a swing rod and a driving part for driving the swing rod to move. The locking / unlocking between the pot lid assembly and the inner pot is achieved through the movement of the swing rod. During the movement of the swing rod, there are an opening lid unlocking position and a closing lid locking position. A first detection element and a second detection element are arranged on the pot lid assembly. The first detection element is used to detect the swing rod at the opening lid unlocking position, and the second detection element is used to detect the swing rod at the closing lid locking position. A high-pressure stop device is arranged on the pot lid assembly.

Specific embodiments

[0027] To make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model is given in conjunction with the accompanying drawings.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is the orientation or positional relationship based on the normal use of the product.

[0029] The terms "first", "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include at least one of such features.

[0030] Refer to Figures 1 - 11, an embodiment of the present utility model provides a high-pressure stop integrated structure with multiple detections, including: a pot lid assembly and an inner pot 1. The pot lid assembly includes an opening / closing lid device, and the opening / closing lid device includes a swing rod 2 and a driving part for driving the movement of the swing rod 2. The locking / unlocking between the pot lid assembly and the inner pot 1 is realized through the movement of the swing rod 2. In the locked state, the user cannot open the pot lid assembly by external force. In the unlocked state, the user can open the pot lid assembly by external force; during the movement of the swing rod 2, there are an opening lid unlocking position and a closing lid locking position. The opening lid unlocking position is the unlocked state, and the closing lid locking position is the locked state. A first detection element and a second detection element are arranged on the pot lid assembly. The first detection element is used to detect the swing rod 2 at the opening lid unlocking position, that is, to detect and judge whether the swing rod 2 is at the opening lid unlocking position; the second detection element is used to detect the swing rod 2 at the closing lid locking position, that is, to detect and judge whether the swing rod 2 is at the closing lid locking position; a high-pressure stop device is arranged on the pot lid assembly. The high-pressure stop device includes a liftable stop rod 5. The stop rod 5 is used to rise when the pressure in the inner pot 1 reaches a preset higher pressure, so as to block the swing rod 2 at the closing lid locking position, so that the unlocking operation cannot be performed through the swing rod 2 when there is pressure in the inner pot 1; the stop rod 5 descends and resets when the pressure in the inner pot 1 drops to a preset lower pressure. At this time, the stop rod 5 does not block the movement of the swing rod 2, so that only when the inner pot is in a low-pressure or non-pressure state, that is, when the stop rod 5 descends, can the swing rod 2 move to unlock, avoiding accidental unlocking when the inner pot is under pressure, and the use is reliable and safe; a third detection element for detecting the rise of the stop rod 5 is arranged between the swing rod 2 and the stop rod 5. When the stop rod 5 rises, the third detection element can detect the stop rod 5; when the stop rod 5 descends, the third detection element cannot detect the stop rod 5; through the different movement positions of the swing rod in the present utility model, the detection of the opening / closing lid position of the swing rod can be realized, and the detection of the position of the stop rod in the high-pressure stop device can also be realized, achieving dual detection (the dual detection function is integrated in the swing rod to form an integrated detection structure), avoiding the problem of accidental opening of the lid under pressure, and the use is more reliable, safe and stable, and the use experience is good.

[0031] Refer to Figures 2 - 5, the first detection element includes a first magnetic switch 31 and a first magnet 32. The first magnetic switch 31 is arranged on the pot lid assembly, and the first magnet 32 is arranged on the swing rod 2. When the swing rod 2 moves to the open-lid unlocking position, the first magnetic switch 31 detects the first magnet 32. At this time, the first magnetic switch 31 controls the driving part and the swing rod to stop moving; the second detection element includes a second magnetic switch 41 and a second magnet 42. The second magnetic switch 41 is arranged on the pot lid assembly, and the second magnet 42 is arranged on the swing rod 2. When the swing rod 2 moves to the closed-lid locking position, the second magnetic switch 41 detects the second magnet 42. At this time, the second magnetic switch 41 controls the driving part and the swing rod to stop moving; the third detection element includes a third magnetic switch 61 and a third magnet 62. The third magnetic switch 61 is arranged on the swing rod 2, and the third magnet 62 is arranged on the stop rod 5. When the inner pot is pressed upward and the stop rod 5 rises, the third magnetic switch 61 detects the third magnet 62, so as to double-check that the swing rod 2 is in the closed-lid locking position, that is, only when the swing rod 2 is in the closed-lid locking position and the inner pot is pressed upward, the third magnetic switch 61 can detect the third magnet 62; the first magnetic switch, the second magnetic switch and the third magnetic switch can adopt reed switches or Hall switches or other suitable switch parts, and generate a signal indicating in place when detecting the corresponding magnet, and generate a signal indicating not in place when not detecting the corresponding magnet. Only when the third magnetic switch 61 does not detect the third magnet 62, it means that the inner pot is in a non-pressurized or low-pressure state. At this time, manual or automatic lid opening operations can be performed; in this embodiment, after cooking is completed and the inner pot naturally reduces pressure, the stop rod descends. When the signal detected by the third magnetic switch 61 changes from in place to not in place, the third magnetic switch 61 controls the driving part to act, so as to control the swing rod to automatically unlock, facilitating the user to open the lid and being convenient to use.

[0032] Refer to Figures 2 - 5 , a control board is arranged on the pot lid assembly, and the control board can also be arranged on the pot body. The first detection element, the second detection element and the third detection element are all electrically connected to the control board to receive and process the electrical signals of each detection element. The high-pressure stop device further includes a valve cover 71. The stop rod 5 is slidably installed on the valve cover 71 in the vertical direction. The upper end of the stop rod 5 penetrates through the valve cover 71, and the upper part of the stop rod 5 in the rising state blocks the movement of the swing rod. The third magnet 62 is arranged on the upper part of the stop rod 5. An elastic sealing diaphragm 72 is arranged between the valve cover 71 and the pot lid assembly. The elastic sealing diaphragm 72 is made of silica gel or rubber. When the inner pot is pressed upward, the elastic sealing diaphragm 72 elastically deforms upward, thereby driving the stop rod 5 to rise; when the inner pot is in low pressure or non-pressurized state, the elastic sealing diaphragm 72 resets downward, thereby driving the stop rod 5 to descend; a pressure chamber 73 communicating with the inner pot 1 is formed between the elastic sealing diaphragm 72 and the pot lid assembly. The lower end of the pressure chamber 73 is communicated with the inner pot 1. A compression spring 74 is abutted between the valve cover 71 and the stop rod 5, and the stop rod 5 is driven to descend and reset by the compression spring 74.

[0033] Refer to Figures 1 - 3 , an emergency through hole 14 corresponding to the stop lever 5 is provided on the pot lid assembly. The emergency through hole 14 is formed above the stop lever 5, and a detachable sealing plug 15 is provided at the emergency through hole 14. The provided emergency through hole is used for the abnormal situation where the stop lever still does not descend when there is no pressure. When using an artificial external force, a columnar object is used to pass through the emergency through hole 14 to press down the stop lever to achieve the purpose of opening the pot lid.

[0034] Refer to Figures 4 - 8 , a weight device is provided on the pot lid assembly. The weight device includes an exhaust pipe 81, a weight 82, and a liftable weight ejector rod 83. The weight 82 is placed at the upper end of the exhaust pipe 81. The weight 82 blocks the upper port of the exhaust pipe 81 under its own gravity. The lower port of the exhaust pipe 81 is communicated with the inner cavity of the inner pot 1. The weight ejector rod 83 is used to push up the weight 82 to open the upper port of the exhaust pipe 81 for exhaust. A linkage component is provided between the swing rod 2 and the weight ejector rod 83. When the swing rod 2 moves from the closed lid locking position to the open lid unlocking position, the swing rod 2 drives the weight ejector rod 83 to move upward through the linkage component to push up the weight 82. The linkage component includes a transmission plate 9 slidably arranged on the pot lid assembly. A limit bolt 16 is provided on the pot lid assembly. A second chute 17 corresponding to the limit bolt 16 is provided on the transmission plate 9. The transmission plate 9 slides along the extension direction of the second chute 17. The transmission plate 9 is driven to slide by the swing rod 2. A groove 91 corresponding to the weight ejector rod 83 is provided on the transmission plate 9. An inclined guide surface 92 for lifting the weight ejector rod 83 is provided in the groove 91. When in the closed lid locking position, the weight ejector rod 83 is located in the groove 91 and is in a descending state. At this time, the weight 82 blocks the upper end of the exhaust pipe 81. When in the open lid unlocking position, the weight ejector rod 83 rises along the inclined guide surface 92 to push open the weight 82 for exhaust. A blocking portion 901 is provided on the transmission plate 9. When the swing rod 2 is in the closed lid locking position and the stop lever 5 rises, at this time, the upper end height of the stop lever 5 is slightly higher than the blocking portion 901. The stop lever 5 blocks the blocking portion 901 to limit the movement of the transmission plate 9 and the swing rod 2 in the closed lid locking position, avoiding the sliding of the transmission plate 9 and the rotation of the swing rod 2 when the inner pot is under pressure, and the operation is stable and reliable.

[0035] Refer to Figure 1 , Figure 4 and Figure 5, the lid assembly includes a housing 10 and a lid buckle ring 11 rotatably connected to the housing 10. The swing rod 2 is rotatably connected to the housing 10. The lid buckle ring 11 locks / unlocks with the inner pot 1 through its circumferential rotation. There is a protrusion 111 on the lid buckle ring 11, and a slot 201 for engaging the protrusion 111 is provided on the swing rod 2. The swing of the swing rod 2 drives the rotation of the lid buckle ring 11, and the inner pot is locked / unlocked according to the circumferential rotation position of the lid buckle ring 11. The lid buckle ring is a prior art and will not be elaborated here. The driving part includes a motor 12 and a turntable 13. The motor 12 is a reduction motor. The turntable 13 is connected to the output end of the motor 12. There is a convex column 131 on the turntable 13, and a first chute 202 corresponding to the convex column 131 is provided on the swing rod 2. The forward and reverse rotation of the motor 12 drives the swing rod 2 to swing in the corresponding direction, so as to realize the locking / unlocking function between the lid assembly and the inner pot, and the use experience is good.

[0036] The integrated structure of high-pressure stop and multiple detections of the present invention can detect the opening and closing positions of the swing rod through different movement positions of the swing rod, and can also detect the position of the stop rod in the high-pressure stop device, realizing double detections, avoiding the problem of accidentally opening the lid under pressure, and being more reliable, safe and stable in use, with a good use experience. When the inner pot naturally depressurizes after cooking is completed and the signal detected by the third magnetic switch changes from in place to not in place when the stop rod descends, the third magnetic switch controls the driving part to act at this time, so as to control the swing rod to automatically unlock, facilitating the user to open the lid, which is convenient to use. The emergency through hole is used for the abnormal situation where the stop rod still does not descend when there is no pressure. A columnar object is used to press down the stop rod through the emergency through hole manually to achieve the purpose of opening the lid, so that the lid assembly can still be opened in case of abnormal situations. The forward and reverse rotation of the motor drives the swing rod to swing in the corresponding direction, so as to realize the locking / unlocking function between the lid assembly and the inner pot, and the use experience is good.

[0037] In addition, referring to Figures 1 - 11 , the present invention also provides an electric pressure cooker, which includes the above-mentioned integrated structure of high-pressure stop and multiple detections, and also has the beneficial effects of the integrated structure of high-pressure stop and multiple detections, which will not be elaborated here.

[0038] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
