[0002] The rice cooker is a modern cooking appliance capable of various food processing functions, including steaming, boiling, stewing, simmering, and braising. As rice becomes increasingly popular as a staple food, the rice cooker has become a common cooking tool. With the continuous improvement of people's living standards, smart rice cookers have been developed that automatically add and rinse rice, eliminating the need for human intervention throughout the cooking process. However, the components required to perform the rinsing function in most smart rice cookers on the market are complex, hindering structural simplicity and cost reduction. Summary of the Invention

[0003] Based on this, the present invention aims to overcome the defects of the prior art and provide an electric rice cooker rice washing component and an electric rice cooker, which are conducive to structural simplification and cost reduction.

[0004] A rice-washing assembly for an electric rice cooker and an electric rice cooker, comprising a screw shaft, a nut seat, and a water spray and suction sleeve, wherein the screw shaft has a threaded section, the nut seat is mounted on the threaded section, and the nut seat can move with the rotation of the screw shaft by cooperating with the threaded section. The screw shaft is provided with a hollow channel, and the hollow channel has a first opening and a second opening, the first opening being used to communicate with a water spray and suction device, the water spray and suction sleeve is provided with a water spray and suction hole, and the second opening is communicated with the water spray and suction hole, the water spray and suction sleeve is sleeved on one end of the screw shaft near the second opening, and the water spray and suction sleeve is fixed on the nut seat, and the water spray and suction sleeve can enter or exit the pot body as the nut seat moves.

[0005] The rice-washing assembly of the electric rice cooker, when realizing the automatic rice-washing function, first controls the screw shaft to rotate in the forward direction, so that the nut seat and the threaded section cooperate to move with the rotation of the screw shaft, and the water-spraying and absorbing sleeve can enter the pot body with the movement of the nut seat. Then, the water-spraying and absorbing device is used to spray water into the pot body through the water-spraying and absorbing holes to wash the rice. Then, the water in the pot body is sucked away through the water-spraying and absorbing holes by the water-spraying and absorbing device. Finally, the screw shaft is controlled to rotate in the reverse direction, so that the nut seat and the threaded section cooperate to move with the rotation of the screw shaft, and the water-spraying and absorbing sleeve can be withdrawn from the pot body with the movement of the nut seat, so that the electric rice cooker can perform the rice-washing operation. The rice-washing assembly of the electric rice cooker can effectively realize the automatic rice-washing function, and its simple structure is conducive to reducing the cost.

[0006] In one embodiment, the water-spraying and suctioning jacket is provided with a stirring member, and the threaded section is provided with a stopper for preventing the nut seat from moving. The nut seat can rotate with the rotation of the screw shaft by cooperating with the stopper, and the water-spraying and suctioning jacket can drive the stirring member to rotate with the rotation of the nut seat. When the nut seat moves to the position of the stopper, the nut seat and the stopper cooperate to rotate with the rotation of the screw shaft, driving the stirring member on the water-spraying and suctioning jacket to rotate and stir the rice. Simultaneously, the water-spraying and suctioning equipment sprays water into the pot through the water-spraying and suctioning holes, thereby fully washing the rice.

[0007] In one embodiment, the stop portion is located at one end of the threaded section close to the second opening, which is beneficial for shortening the length of the screw shaft, simplifying the structure and reducing costs.

[0008] In one embodiment, the diameter of the water-spraying and water-absorbing holes is less than 2 mm, so that normal whole rice cannot completely enter the water-spraying and water-absorbing holes, ensuring that water flows smoothly through the water-spraying and water-absorbing holes.

[0009] In one embodiment, there are a plurality of water spraying and suction holes, and the plurality of water spraying and suction holes are arranged at intervals on the water spraying and suction sleeve. Since it is difficult for rice to block all the water spraying and suction holes, this can ensure that water is sucked away smoothly and increase the water flow rate.

[0010] In one embodiment, the rice-washing assembly of the electric rice cooker further comprises a driving mechanism for driving the screw shaft to rotate, wherein the driving mechanism is drivably connected to the screw shaft. The driving mechanism drives the screw shaft to rotate, thereby driving the nut seat and the water spraying and absorbing sleeve to move or rotate.

[0011] In one embodiment, the driving mechanism includes a forward and reverse motor, and the screw shaft is the output shaft of the forward and reverse motor. The forward and reverse motor can directly control the screw shaft to rotate in the forward direction, and the reverse motor can directly control the screw shaft to rotate in the reverse direction.

[0012] In one embodiment, the drive mechanism includes a forward / reversible motor, a first gear disposed on an output shaft of the forward / reversible motor, and a second gear disposed on the screw shaft, the first gear meshing with the second gear. When the forward / reversible motor rotates forward, the first gear and the second gear cooperate to indirectly control forward rotation of the screw shaft, and when the forward / reversible motor rotates reversely, the first gear and the second gear cooperate to indirectly control reverse rotation of the screw shaft.

[0013] An electric rice cooker comprises the above-mentioned electric rice cooker rice washing component.

[0014] The electric rice cooker includes the electric rice cooker rice-washing assembly, and therefore also has the technical effect of the electric rice cooker rice-washing assembly, which is conducive to structural simplification and cost reduction.

[0015] In one embodiment, the electric rice cooker further comprises a water spraying and suction device, the first port being connected to the water spraying and suction device, the water spraying and suction device spraying water into the first port and sucking water out of the first port, cooperating with the rice washing component of the electric rice cooker to realize the function of automatic rice washing.

[0023] Example 1

[0024] Combine Figure 1As shown, in one embodiment, an electric rice cooker rice washing assembly and an electric rice cooker are provided, including a screw shaft 10, a nut seat 20 and a water spray and suction sleeve 30, the screw shaft 10 having a threaded section 11, the nut seat 20 being mounted on the threaded section 11, the nut seat 20 being able to move with the rotation of the screw shaft 10 by cooperating with the threaded section 11, the screw shaft 10 being provided with a hollow channel, the hollow channel having a first port 12 and a second port 13, the first port 12 being used to communicate with a water spray and suction device, the water spray and suction sleeve 30 being provided with a water spray and suction hole 31, the second port 13 being connected to the water spray and suction hole 31, the water spray and suction sleeve 30 being sleeved on one end of the screw shaft 10 near the second port 13, and the water spray and suction sleeve 30 being fixed on the nut seat 20, the water spray and suction sleeve 30 being able to enter or exit the pot body as the nut seat 20 moves.

[0025] The rice-washing assembly of the electric rice cooker, when realizing the automatic rice-washing function, first controls the screw shaft 10 to rotate forward, so that the nut seat 20 and the threaded section 11 cooperate to move with the rotation of the screw shaft 10, and the water spraying and suction sleeve 30 can enter the pot body with the movement of the nut seat 20. Then, the water spraying and suction device is used to spray water into the pot body through the water spraying and suction holes 31 to wash the rice. Then, the water in the pot body is sucked away through the water spraying and suction holes 31 by the water spraying and suction device. Finally, the screw shaft 10 is controlled to rotate backward, so that the nut seat 20 and the threaded section 11 cooperate to move with the rotation of the screw shaft 10, and the water spraying and suction sleeve 30 can be withdrawn from the pot body with the movement of the nut seat 20, so that the electric rice cooker can perform the rice-washing operation. The rice-washing assembly of the electric rice cooker can effectively realize the automatic rice-washing function, and its structure is simple, which is conducive to reducing the cost.

[0026] Combine Figure 1 As shown, the water-spraying and suctioning jacket 30 is provided with a stirring member 32, and the threaded section 11 is provided with a stopper 14 for preventing the nut seat 20 from moving. The nut seat 20 can rotate with the rotation of the screw shaft 10 by cooperating with the stopper 14. The water-spraying and suctioning jacket 30 can drive the stirring member 32 to rotate with the rotation of the nut seat 20. When the nut seat 20 moves to the position of the stopper 14, the nut seat 20 cooperates with the stopper 14 to rotate with the rotation of the screw shaft 10, driving the stirring member 32 on the water-spraying and suctioning jacket 30 to rotate and stir the rice. At the same time, the water-spraying and suctioning equipment sprays water into the pot through the water-spraying and suctioning holes 31, completing the thorough washing of the rice.

[0027] In this embodiment, the stirring member 32 is a stirring blade. Of course, the stirring member 32 can also adopt other forms, not limited to this. In this embodiment, the stop portion 14 is a bump. Of course, the stop portion 14 can also adopt other forms, not limited to this.

[0028] In this embodiment, the stopper 14 is located at one end of the threaded segment 11 near the second opening 13. This helps shorten the length of the screw shaft 10, simplify the structure, and reduce costs. In other embodiments, the stopper 14 can also be located in the middle of the threaded segment 11.

[0029] Optionally, the diameter of the water spraying and suction holes 31 is less than 2 mm. This prevents normal whole rice from completely entering the water spraying and suction holes 31, ensuring smooth water flow through the water spraying and suction holes 31. Multiple water spraying and suction holes 31 are provided, spaced apart on the water spraying and suction jacket 30. Since rice is unlikely to clog all of the water spraying and suction holes 31, this ensures smooth water absorption and increases water flow.

[0030] Combine Figure 1 As shown, the rice-washing assembly of the electric rice cooker further includes a driving mechanism 40 for driving the screw shaft 10 to rotate, and the driving mechanism 40 is drivingly connected to the screw shaft 10. The driving mechanism 40 drives the screw shaft 10 to rotate, thereby driving the nut seat 20 and the water spraying and suction sleeve 30 to move or rotate.

[0031] In this embodiment, the driving mechanism 40 includes a forward and reverse motor 41, and the screw shaft 10 is the output shaft of the forward and reverse motor 41. The forward and reverse motor 41 can directly control the screw shaft 10 to rotate in the forward direction, and the reverse motor 41 can directly control the screw shaft 10 to rotate in the reverse direction.

[0032] Combine Figure 1 As shown, in one embodiment, an electric rice cooker is provided, comprising the above-mentioned electric rice cooker rice washing component.

[0033] The electric rice cooker includes the electric rice cooker rice-washing assembly, and therefore also has the technical effect of the electric rice cooker rice-washing assembly, which is conducive to structural simplification and cost reduction.

[0034] Furthermore, the electric rice cooker further comprises a water spraying and absorbing device, the first port 12 being connected to the water spraying and absorbing device. The water spraying and absorbing device sprays water into the first port 12 and absorbs water from the first port 12, cooperating with the rice washing component of the electric rice cooker to realize the function of automatic rice washing.

[0035] Example 2

[0036] Combine Figure 2As shown, the difference between the rice-washing assembly of the electric rice cooker described in the second embodiment and the rice-washing assembly of the first embodiment is that: in the second embodiment, the driving mechanism 40 includes a forward and reverse motor 41, the output shaft of which is provided with a first gear 42, and the screw shaft 10 is provided with a second gear 15, and the first gear 42 and the second gear 15 are meshed. When the forward and reverse motor 41 rotates forward, the first gear 42 and the second gear 15 cooperate to indirectly control the forward rotation of the screw shaft 10. When the forward and reverse motor 41 rotates reverse, the first gear 42 and the second gear 15 cooperate to indirectly control the reverse rotation of the screw shaft 10. Of course, the driving mechanism 40 can also adopt other forms, and is not limited to this.

[0037] The various technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
