Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric rice cooker technology, and in particular to an electric rice cooker capable of pressure-preventing opening and pressure detection. Background Technology
[0002] Currently, rice cookers on the market generally need a pressure-prevention function to prevent the lid from opening due to high temperature and a pressure detection function to monitor the temperature inside the pot in real time. Therefore, existing rice cookers are generally equipped with a pressure-prevention device to prevent the lid from opening due to pressure and a pressure detection device to detect the pressure. However, because rice cookers are equipped with separate pressure-prevention devices and pressure detection devices, the structure of rice cookers is more complex and the production cost is higher. Utility Model Content
[0003] In order to overcome at least one of the defects mentioned above in the prior art, this utility model provides a rice cooker that can prevent opening under pressure and detect pressure, so as to solve the problems that the existing rice cookers with pressure prevention and pressure detection functions have a complex structure and high production cost.
[0004] This utility model discloses a rice cooker capable of pressure-resistant opening and pressure detection, comprising a cover assembly, a locking assembly, a magnetic float assembly, and a magnetic switch. The cover assembly is used to flip and close onto the inner pot. The locking assembly is movably mounted on the cover assembly and can move radially relative to the cover assembly along the inner pot to lock with it. The magnetic float assembly is movably mounted on the cover assembly. When the cover assembly is locked with the inner pot, the magnetic float assembly can move relative to the cover assembly under the pressure inside the inner pot to limit the locking assembly, thus keeping it in the locked state. The magnetic switch is mounted on the cover assembly and is used to sense the movement of the magnetic float assembly to detect the pressure inside the inner pot.
[0005] As an optional implementation, in this embodiment of the present invention, the cover plate assembly includes a cover plate and an inner liner arranged sequentially from the direction closest to the inner pot to the direction furthest from the inner pot. The magnetic switch is disposed on the inner liner. The cover plate has a first mounting hole, and the inner liner has a second mounting hole. The magnetic float assembly includes a float and a magnetic component. The float is movably disposed in the first mounting hole, and the magnetic component is movably disposed in the second mounting hole. The float moves under the pressure inside the inner pot and pushes the magnetic component. The magnetic component moves to limit the locking assembly and is sensed by the magnetic switch.
[0006] As an optional implementation, in this embodiment of the present invention, the magnetic float assembly further includes an elastic sealing ring, one end of which is fitted into the second mounting hole, the magnetic component is movably inserted through the elastic sealing ring, and the other end of which is fitted onto the end of the magnetic component near the cover plate.
[0007] As an optional implementation, in this embodiment of the present invention, the locking assembly includes a linkage slider and a latch. The linkage slider is slidably disposed on the cover plate assembly along the radial direction of the inner pot. The latch is disposed on the linkage slider. Under the action of an external force, the linkage slider drives the latch to move in a direction away from the axis of the inner pot, thereby unlocking the latch and the inner pot. Alternatively, when the external force disappears, the linkage slider resets and drives the latch to move in a direction toward the axis of the inner pot, thereby locking the latch and the inner pot.
[0008] As an optional implementation, in this embodiment of the present invention, the linkage slider is provided with a clearance hole. When the linkage slider slides to the point where the latch locks with the inner pot, the magnetic float assembly moves to pass through the clearance hole to limit the linkage slider.
[0009] As an optional implementation, in this embodiment of the present invention, one end of the linkage slider is provided with a groove, and the cover plate assembly is provided with a sliding hanging shaft, which is slidably connected to the groove.
[0010] As an optional implementation, in this embodiment of the present invention, the locking assembly further includes a return spring, the cover plate assembly is provided with a first limiting groove, the other end of the linkage slider is provided with a second limiting groove, and the return spring abuts between the first limiting groove and the second limiting groove.
[0011] As an optional implementation, in this embodiment of the present invention, the locking assembly further includes a handle, which is movably fixed to the cover plate assembly. The handle moves in a direction away from the cover plate assembly to push the linkage slider to move in a direction away from the axis of the inner pot. The handle moves in a direction toward the cover plate assembly to separate from the linkage slider.
[0012] As an optional implementation, in this embodiment of the present invention, the handle is provided with a first inclined surface, and one end of the linkage slider is provided with a second inclined surface adapted to the first inclined surface. When the handle moves away from the cover plate assembly, the first inclined surface pushes the second inclined surface, so that the linkage slider moves away from the axis of the inner pot. When the handle moves towards the cover plate assembly, the first inclined surface separates from the second inclined surface, so that the handle separates from the linkage slider.
[0013] As an optional implementation, in this embodiment of the present invention, the cover plate assembly includes a cover plate and an inner liner arranged sequentially from the direction closest to the inner pot to the direction furthest from the inner pot. The linkage slider is located on the opposite side of the inner liner from the cover plate. One end of the linkage slider is slidably disposed on the inner liner. The latch is located below the inner liner and is provided with a hanging shaft. The inner liner is provided with a clearance groove. The hanging shaft passes through the clearance groove to connect to the other end of the linkage slider.
[0014] Implementing the embodiments of this utility model will have the following beneficial effects:
[0015] This invention relates to a rice cooker comprising an inner pot, a lid assembly, a locking assembly, a magnetic float assembly, and a magnetic switch. The lid assembly can be flipped to cover the inner pot. The locking assembly is movably mounted on the lid assembly and can move radially relative to the lid assembly along the inner pot to lock it in place. The magnetic float assembly is movably mounted on the lid assembly. When the lid assembly is locked to the inner pot, the magnetic float assembly can move relative to the lid assembly under the pressure inside the inner pot to limit the locking assembly, thus keeping it in the locked state. The magnetic switch is located on the lid assembly and is used to sense the movement of the magnetic float assembly to detect the pressure inside the inner pot. This design, through the cooperation of the locking assembly, the magnetic float assembly, and the magnetic switch, allows the rice cooker to simultaneously achieve pressure-prevention and pressure detection functions, thereby simplifying the structure of the rice cooker and reducing its production cost.

Therefore, they should not be construed as limitations on this utility model.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0026] Please refer to the following: Figures 1 to 4This utility model discloses a rice cooker capable of pressure-resistant opening and pressure detection, including an inner pot 1, a cover assembly 2, a locking assembly, a magnetic float assembly 4, and a magnetic switch 5. The cover assembly 2 can be flipped to cover the inner pot 1. The locking assembly is movably mounted on the cover assembly 2 and can move radially relative to the cover assembly 2 along the inner pot 1 to lock with the inner pot 1, so that the cover assembly 2 is locked to the inner pot 1 (e.g., ...). Figure 1 and Figure 2 As shown), the magnetic float assembly 4 is movably mounted on the cover plate assembly 2. When the cover plate assembly 2 is locked with the inner pot 1, the magnetic float assembly 4 can move relative to the cover plate assembly 2 under the pressure inside the inner pot 1 to limit the locking assembly, so that the locking assembly remains in the locked state (as shown). Figure 3 As shown, the magnetic switch 5 is mounted on the cover assembly 2 and is used to sense the movement of the magnetic float assembly 4 to detect the pressure inside the inner pot 1. This design, through the cooperation of the locking assembly, the magnetic float assembly 4, and the magnetic switch 5, allows the rice cooker to simultaneously achieve pressure-prevention and pressure detection functions, thereby simplifying the structure of the rice cooker and reducing its production cost.
[0027] In some embodiments, in order for the magnetic float assembly 4 to achieve the limiting function of the locking assembly, the cover assembly 2 includes a cover 21 and an inner liner 22 arranged sequentially from the direction near the inner pot 1 to the direction away from the inner pot 1. The magnetic switch 5 is disposed on the inner liner 22. The cover 21 is provided with a first mounting hole, and the inner liner 22 is provided with a second mounting hole. The magnetic float assembly 4 includes a float 41 and a magnetic component 42. The float 41 is movably disposed in the first mounting hole, and the magnetic component 42 is movably disposed in the second mounting hole. Under the action of the pressure inside the inner pot 1, the float 41 moves and pushes the magnetic component 42, so that the magnetic component 42 moves to limit the locking assembly. This is to prevent the lid from opening due to pressure. At the same time, as the magnetic component 42 rises and approaches the magnetic switch 5, the magnetic switch 5 senses the magnetic component 42 and sends a pressure signal to the circuit board of the rice cooker.
[0028] Furthermore, considering that when there is no pressure inside the inner pot 1, the magnetic component 42 needs to reset to release the limiting effect on the locking assembly, the magnetic float assembly 4 also includes an elastic sealing ring 43. One end of the elastic sealing ring 43 is fitted into the second mounting hole, and the magnetic component 42 is movably inserted through the elastic sealing ring 43. The other end of the elastic sealing ring 43 is fitted onto the end of the magnetic component 42 near the cover plate 21. When there is pressure inside the inner pot 1, the magnetic component 42 moves towards the locking assembly under the pressure and compresses the elastic sealing ring 43. When there is no pressure inside the inner pot 1, the elastic sealing ring 43 extends and drives the magnetic component 42 to reset. In addition, the elastic sealing ring 43 can also serve as a seal between the magnetic component 42 and the second mounting hole.
[0029] In some embodiments, to achieve locking and unlocking of the locking assembly and the inner pot 1, the locking assembly includes a linkage slider 31 and a latch 32. The linkage slider 31 is slidably mounted on the cover plate assembly 2 along the radial direction of the inner pot 1. The latch 32 is mounted on the linkage slider 31. Under the action of an external force, the linkage slider 31 drives the latch 32 to move in a direction away from the axis of the inner pot 1, thereby unlocking the latch 32 and the inner pot 1 (e.g., Figure 4 As shown), or, when the external force disappears, the linkage slider 31 resets and drives the latch 32 to move along the axis toward the inner pot 1, so that the latch 32 and the inner pot 1 are locked.
[0030] In order to limit the movement of the magnetic float assembly 4 on the linkage slider 31, the linkage slider 31 is provided with a clearance hole 311. When the linkage slider 31 slides to the point where the latch 32 locks with the inner pot 1, the magnetic float assembly 4 moves to pass through the clearance hole 311 to limit the movement of the linkage slider 31.
[0031] In some embodiments, in order to enable the sliding of the linkage slider 31 on the inner liner 22, a groove 312 is provided on one end of the linkage slider 31, and a first hanging shaft 221 is provided on the inner liner 22, the first hanging shaft 221 being slidably connected to the groove 312.
[0032] Furthermore, in order for the linkage slider 31 to reset when the external force disappears, the rice cooker that can raise pressure to prevent opening and detect pressure also includes a reset spring 33. The inner liner 22 is provided with a first limiting groove 222, and the other end of the linkage slider 31 is provided with a second limiting groove 313. The reset spring 33 abuts between the first limiting groove 222 and the second limiting groove 313.
[0033] In some embodiments, in order to drive the sliding of the linkage slider 31, the locking assembly also includes a handle 34, which is movably fixed to the cover plate assembly 2. The handle 34 moves in a direction away from the cover plate assembly 2 to push the linkage slider 31 to move in a direction away from the axis of the inner pot 1. The handle 34 moves in a direction toward the cover plate assembly 2 to separate from the linkage slider 31.
[0034] Furthermore, in order to enable the handle 34 to push the linkage slider 31, the handle 34 is provided with a first inclined surface 341, and one end of the linkage slider 31 is provided with a second inclined surface 314 adapted to the first inclined surface 341. When the handle 34 moves away from the cover plate assembly 2, the first inclined surface 341 pushes the second inclined surface 314, so that the linkage slider 31 moves away from the axis of the inner pot 1. When the handle 34 moves towards the cover plate assembly 2, the first inclined surface 341 and the second inclined surface 314 separate, so that the handle 34 separates from the linkage slider 31.
[0035] In some embodiments, the linkage slider 31 is located on the opposite side of the inner liner 22 to the cover plate 21. One end of the linkage slider 31 is slidably disposed on the inner liner 22. The latch 32 is located below the inner liner 22. The latch 32 is provided with a second lifting shaft 321. The inner liner 22 is provided with a relief groove 223. The second lifting shaft 321 passes through the relief groove 223 to connect to the other end of the linkage slider 31.
[0036] The following is a detailed explanation of the pressure-prevention and pressure detection process of a rice cooker:
[0037] When the handle 34 is pulled away from the cover assembly 2, the handle 34 moves away from the cover assembly 2 to push the linkage slider 31 outward away from the axis, and the latch 32 moves away from the axis of the inner pot 1, so that the latch 32 and the inner pot 1 are unlocked. When the handle 34 is pushed towards the cover assembly 2, the handle 34 separates from the linkage slider 31, and the linkage slider 31 is reset in the direction towards the axis of the inner pot 1 under the action of the return spring 33. The latch 32 moves in the direction towards the axis of the inner pot 1, so that when the latch 32 and the inner pot 1 are locked, the area above the magnetic component 42 is a barrier to the linkage slider 31. Hole 311: If there is pressure inside the inner pot 1, the magnetic component 42 passes through the hole 311 of the linkage slider 31, causing the linkage slider 31 to be unable to rotate in the opening direction. This is to prevent the lid from opening due to pressure. At the same time, as the magnetic component 42 rises and approaches the magnetic switch 5, the magnetic switch 5 senses the magnet on the magnetic component 42 and sends a pressure signal to the circuit board of the rice cooker. When the pressure inside the inner pot 1 drops to zero, the magnetic component 42 descends under the action of the elastic sealing ring 43. At this time, the magnetic component 42 moves away from the magnetic switch 5, and the magnetic switch 5 sends a zero-pressure signal to the circuit board of the rice cooker. This is the zero-pressure detection function.
[0038] This utility model provides a rice cooker capable of pressure-resistant opening and pressure detection. The rice cooker includes an inner pot 1, a cover assembly 2, a locking assembly, a magnetic float assembly 4, and a magnetic switch 5. The cover assembly 2 can be flipped to cover the inner pot 1. The locking assembly is movably mounted on the cover assembly 2 and can move radially relative to the cover assembly 2 along the inner pot 1 to lock with it. The magnetic float assembly 4 is movably mounted on the cover assembly 2. When the cover assembly 2 is locked with the inner pot 1, the magnetic float assembly 4 can move relative to the cover assembly 2 under the pressure inside the inner pot 1 to limit the locking assembly, keeping it in the locked state. The magnetic switch 5 is mounted on the cover assembly 2 and is used to sense the movement of the magnetic float assembly 4 to detect the pressure inside the inner pot 1. By adopting this design approach, through the cooperation of the locking component, the magnetic float component 4, and the magnetic switch 5, the rice cooker can simultaneously achieve pressure-prevention and pressure detection functions, thereby simplifying the structure of the rice cooker and reducing its production cost.
[0039] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
