When the user needs to serve the rice, one hand often holds the rice spoon and the other hand holds the rice bowl. In this case, one hand is also needed to unlock the cooker lid, which is rather inconvenient. At the same time, due to the need to manually open the lid, the user may need to temporarily place the rice spoon on the countertop or other places to free up one hand to lift the cooker lid. This not only increases the risk of the rice spoon being contaminated but also affects the cleanliness of the kitchen. In addition, the frequent hand-changing actions during the rice-serving process not only reduce the rice-serving efficiency but also bring additional troubles to the user.

[0022] The following details the embodiments of the present utility model with reference to the accompanying drawings.

[0023] As shown Figures 1 to 4 in the figure, the utility model discloses an electric rice cooker with an automatic lid opening function, which includes a cooker body 1. An inner pot 2 is arranged inside the cooker body 1, and a heating element 3 capable of heating the inner pot 2 is provided. A cooker lid 4 is rotatably connected to the upper part of the cooker body 1. A locking structure 5 capable of locking the two is arranged between the cooker body 1 and the cooker lid 4. A rice spoon rack 6 is also arranged on the cooker body 1. A rice spoon 7 is detachably connected to the rice spoon rack 6. A first driving mechanism 8 capable of driving the locking structure 5 to unlock when the rice spoon 7 is separated from the rice spoon rack 6 is further arranged on the cooker body 1.

[0024] The cooker body 1 serves as the main body of the electric rice cooker. The inner pot 2 is used to hold food materials, and the heating element 3 provides heat for the inner pot 2 to cook the food materials. The inner pot 2 is usually made of metal material to have good heat conduction performance. In the embodiment, the heating element 3 is a heating plate arranged below the inner pot 2. The cooker lid 4 can seal the cooker body 1, which helps the food materials to be cooked faster, and locks the cooker body 1 and the cooker lid 4 through the locking structure 5 to ensure that the cooker lid 4 will not be accidentally opened during the cooking process, guaranteeing safety. The rice spoon rack 6 is used to place the rice spoon 7, and through cooperation with the first driving mechanism 8, when the rice spoon 7 is separated from the rice spoon rack 6, the locking of the cooker body 1 and the cooker lid 4 by the locking structure 5 can be released, thus realizing automatic lid opening.

[0025] Through the setting of the first driving mechanism 8, when the rice spoon 7 is separated from the rice spoon rack 6, the first driving mechanism 8 releases the locked state of the cooker lid 4, so that the user only needs to remove the rice spoon 7 to unlock the cooker lid 4, improving convenience. Through the setting of the rice spoon rack 6, a fixed position can be provided for the rice spoon 7, reducing the pollution problem caused by the random placement of the rice spoon 7. Through the cooperative setting of the rice spoon 7 and the first driving mechanism 8, the lid opening process is automated. The user can hold a rice bowl with one hand and use the rice spoon with the other hand during the rice serving process, reducing the number of hand changes and improving the rice serving efficiency.

[0026] A magnetic area 73 is arranged on the rice spoon 7. The first driving mechanism 8 includes a Hall element 81 arranged on the cooker body 1 and capable of sensing the magnetic area 73, and a control unit 82 electrically connected to the Hall element 81 and capable of controlling the locking structure 5 to unlock.

[0027] The magnetic region 73 on the rice spoon 7 is used to interact with the Hall element 81 in the first driving mechanism 8. The magnetic region 73 can be made of a magnetic component such as a magnet. When the rice spoon 7 is taken away from the rice spoon rack 6, the change in the magnetic field between the magnetic region 73 and the Hall element 81 will be detected and a signal will be sent to the control unit 82. In the embodiment, the control unit 82 is a control circuit board. The control unit 82 can also be a device such as a programmable logic controller. The control unit 82 receives the signal from the Hall element 81 and controls the unlocking of the locking structure 5 according to the signal. In the embodiment, a comparator is provided between the output end of the Hall element 81 and the control unit 82. The output of the Hall element is connected to one input end of a comparator, and a suitable reference voltage is set at the other input end of the comparator. When there is no magnetic field or the magnetic field is very weak, the Hall voltage is lower than the reference voltage, and the comparator outputs a signal. Thus, in the case of no magnetic field or a very weak magnetic field, the Hall element 81 can output a signal through the comparator to represent the current state. It is also possible for the Hall element 81 to directly output a signal to the control unit 82. When there is no magnetic field or the magnetic field is very weak, the Hall element 81 stops outputting a signal to the control unit 82, so that the control unit 82 executes the action of controlling the unlocking of the locking structure 5. Through the settings of the Hall element 81, the magnetic region 73, and the control unit 82, the function of unlocking the locking of both the pot body 1 and the pot lid 4 by the locking structure 5 when the rice spoon 7 is separated from the rice spoon rack 6 is realized.

[0028] The rice spoon 7 includes a food scooping part 71 and a holding part 72, and the magnetic region 73 is arranged on the holding part 72.

[0029] The food scooping part 71 is used for scooping food, and the holding part 72 is the part where the user holds the rice spoon. The magnetic region 73 is arranged on the holding part 72 and is used to interact with the Hall element 81 in the first driving mechanism 8. When the rice spoon 7 is picked up, the magnetic region 72 leaves the position of the rice spoon rack 6, triggering the Hall element 81, and then unlocking the pot lid 4 through the control unit 82. Arranging the magnetic region 73 on the holding part 72 can reduce the influence on the normal use of the rice spoon 7.

[0030] The magnetic region 73 is arranged at one end of the holding part 72 away from the food scooping part 71, and a limiting block 61 capable of restricting the swaying of the rice spoon 7 is arranged on the rice spoon rack 6.

[0031] The limiting block 61 can restrict the swaying of the rice spoon 7 on the rice spoon rack 6, ensure that the rice spoon 7 is placed stably, and prevent the rice spoon 7 from accidentally falling or shaking when not in use. At the same time, the limiting block 61 can ensure that the rice spoon 7 and the Hall element 81 are in a suitable position for the Hall element 81 to work.

[0032] The limiting block 61 is an elastic block capable of pressing the magnetic region 73 towards the direction close to the Hall element 81.

[0033] The elastic limiting block 61 can press the magnetic region 73 on the rice spoon 7 towards the direction close to the Hall element 81, ensuring that when the rice spoon 7 is placed on the rice spoon rack 6, there is an appropriate distance between the magnetic region 73 and the Hall element 81, so as to ensure that the Hall element 81 can accurately detect the magnetic region 73.

[0034] The first driving mechanism 8 can also be realized by other implementation manners. For example, a mechanical connection structure is provided between the rice spoon 7 and the locking structure 5, so that when the rice spoon 7 leaves the rice spoon rack 6, the locking structure 5 is driven by the mechanical connection structure to be unlocked. Specifically, a mechanical trigger is provided on the rice spoon rack 6, the rice spoon 7 is provided with a connecting portion connected to the mechanical trigger, a connecting rod assembly or a chain assembly is provided between the trigger and the locking structure 5, and the locking structure 5 is a sliding lock or a rotary lock connected to the connecting rod assembly or the chain assembly. When the rice spoon 7 is placed on the mechanical trigger through the connecting portion, the rice spoon 7 keeps the trigger in a locked state by means of gravity or the like. When the rice spoon 7 is picked up, the mechanical trigger drives the connecting rod assembly or the chain assembly to transmit the force to the locking structure 5, so that it slides or rotates to unlock the pot cover 4.

[0035] The locking structure 5 includes an electromagnet 51 provided on the pot body 1, a magnetic portion 52 matched with the electromagnet 51 is provided at the corresponding position of the pot cover 4, and the control unit 82 is electrically connected to the electromagnet 51.

[0036] The electromagnet 51 is provided on the pot body 1, and its magnetism is controlled by current. When the electromagnet 51 is powered on, a magnetic field is generated to attract the magnetic portion 73 on the pot cover 4, so as to lock the pot cover 4. After power off, the electromagnet 51 loses magnetism and the pot cover 4 is unlocked. The control unit 82 is connected to the electromagnet 51 through a circuit. When the rice spoon 7 is picked up, the magnetic region 73 on the rice spoon 7 leaves the Hall element 81 on the rice spoon rack 6. After the control unit 82 receives the signal, it cuts off the power supply of the electromagnet 51, so as to unlock the pot cover 4.

[0037] The locking structure 5 has other implementation manners. For example, a mechanical bolt or other forms of locking parts are driven by a cylinder or a pneumatic valve to achieve locking, and a reset part such as a spring pulls the locking structure back to the unlocking position after the cylinder or the pneumatic valve deflates.

[0038] A second driving mechanism 9 capable of driving the pot cover 4 to rotate and open when the locking structure 5 is unlocked is further provided between the pot body 1 and the pot cover 4.

[0039] The second driving mechanism 9 can automatically drive the pot cover 4 to rotate and open after the locking structure 5 is unlocked, realizing the automatic opening of the pot cover 4 and improving the convenience of use.

[0040] A rotating shaft 91 for connecting the pot body 1 and the pot lid 4 is provided between the pot body 1 and the pot lid 4. The second driving mechanism 9 includes a torsion spring 92 provided on the rotating shaft 91. One end of the torsion spring 92 is connected to the pot body 1, and the other end of the torsion spring 92 is connected to the pot lid 4.

[0041] The pot body 1 and the pot lid 4 are connected by the rotating shaft 91, so that the pot lid 4 rotates around the rotating shaft 91 to realize the opening and closing actions. The torsion spring 92 is installed on the rotating shaft 91, with one end connected to the pot body 1 and the other end connected to the pot lid 4. Thus, after the locking structure 5 is unlocked, a torque is provided to drive the pot lid 4 to automatically rotate and open. A damping spring can be added between the torsion spring 92 and the pot body 1 and the pot lid 4 to provide resistance during the opening process of the pot lid 4, making the opening action of the pot lid 4 smoother and avoiding sudden opening caused by the rapid release of the torsion spring 92.

[0042] The second driving mechanism 9 has other implementation manners, such as driving the opening of the pot lid 4 by an electric motor, a cylinder, etc., and connecting it to a control circuit, so that after the locking structure 5 is unlocked, it automatically drives the pot lid 4 to rotate and open.
