Technical Field

[0001] This utility model relates to the field of rice cooker technology, and in particular to a multifunctional rice cooker. Background Technology

[0002] As people's pace of life continues to accelerate, they do not have enough time to cook, thus failing to meet their dietary needs. Against this backdrop, the rice cooker came into being.

[0003] Existing rice cookers produce rice or porridge with a constant output of heat, which sometimes results in rice with burnt bits at the bottom or porridge that is undercooked. Utility Model Content

The protrusion is rotatably mounted on the steps. When the protrusion rotates into the groove, the inner pot descends, causing the pressure sensor to contract downward and transmit the contraction amplitude signal to the control module. The control module transmits the signal to the heating plate to output different amounts of heat.

[0006] A further preferred embodiment of this utility model is: the step includes a first step and a second step, the first step being higher than the second step, and the groove being disposed on the first step.

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0024] This embodiment mainly describes a multi-functional rice cooker, as detailed below:

[0025] A multi-functional rice cooker includes a pot body 3 and an inner pot 2. The edge of the pot body 3 is provided with a lid 4, which is rotatably connected to the edge of the pot body 3. The edge of the lid 4 is embedded with a locking groove 8, and a movable locking tongue 9 is provided in the locking groove 8. The edge of the pot body 3 is provided with a latch 7. When the lid 4 is closed on the pot body 3, the latch 7 is engaged in the locking groove 8 and locked with the locking tongue 9, thus locking the lid 4 and the pot body 3.

[0026] The cover 4 has a handle 10 on its surface. The handle 10 has a button 11 that connects to the locking tongue 9. When the user grips the handle 10, the cover 4 can be opened by pressing the button 11 on the handle 10.

[0027] An exhaust valve 1 is installed through the lid 4. When the food in the pot 3 is cooked and boiling, hot air is discharged from the exhaust valve 1 to balance the pressure difference inside and outside the pot 3, making it easier for the user to open the lid 4.

[0028] The pot body 3 has a cavity inside, and a pressure sensor 14 is retractably installed at the bottom of the cavity. The inner liner 2 is installed inside the cavity, and the edge of the cavity has a step. Specifically, the step is divided into a first step 15 and a second step 16, where the first step 15 is higher than the second step 16. Several grooves 6 are evenly distributed on the first step 15. Several protrusions 5 are provided on the edge of the inner liner 2. The number of grooves 6 and protrusions 5 is the same. Specifically, the number of grooves 6 and protrusions 5 is three.

[0029] When the inner liner 2 is rotatably mounted on the first step 15 via the protrusion 5, the bottom of the inner liner 2 abuts against the pressure sensor 14. At this time, the pressure sensor 14 retracts downward with a small amplitude. When the protrusion 5 rotates to the groove 6 on the first step 15, the protrusion 5 is inserted into the groove 6 downward, causing the protrusion 5 to move downward from the first step 15 to the second step 16. At the same time, the inner liner 2, which is in contact with the pressure sensor 14, moves downward, causing the pressure sensor 14 to retract downward with a large amplitude.

[0030] A heating plate 13 is provided at the bottom of the cavity, and a through hole is opened in the middle of the heating plate 13. The pressure sensor 14 extends from the through hole and abuts against the bottom of the inner pot 2. A control module 12 is embedded in the pot body 3. The heating plate 13 and the pressure sensor 14 transmit the signal of the downward contraction of the pressure sensor 14 through the control module 12. When the pressure sensor 14 contracts downward, the control module 12 receives the signal and judges the contraction amplitude, and then transmits the signal to the heating plate 13. The heating plate 13 outputs different heat according to different contraction amplitude signals of the pressure sensor 14 to heat the inner pot 2 and cook the food.

[0031] In summary, the multi-functional rice cooker has a control module 12 embedded in its pot body 3. The control module 12 is used to connect the heating plate 13 and the pressure sensor 14. The pot body 3 has a cavity, and the edge of the cavity has a first step 15 and a second step 16. The first step 15 has three grooves 6. The inner pot 2 is nested inside the cavity, and the edge of the inner pot 2 has three protrusions 5 corresponding to the grooves 6. This can be divided into two cases:

[0032] In the first scenario, the inner liner 2 is attached to the first step 15 via the protrusion 5. The bottom of the inner liner 2 abuts against the pressure sensor 14. The pressure sensor 14 retracts downward with a small amount of contraction. The pressure sensor 14 transmits the downward contraction amount as a signal to the control module 12. The control module 12 receives the signal and transmits it to the heating plate 13. The heating plate 13 receives the signal and inputs the corresponding heat to heat the inner liner 2.

[0033] In the second scenario, the inner liner 2 rotates on the first step 15 via the protrusion 5 until the protrusion 5 is engaged in the groove 6 of the first step 15, causing the protrusion 5 to move downwards from the first step 15 to the second step 16. At the same time, the inner liner 2 moves downwards, squeezing the pressure sensor 14, causing the pressure sensor 14 to contract downwards. The contraction amplitude is large, and the pressure sensor 14 transmits the downward contraction amplitude as a signal to the control module 12. The control module 12 receives the signal and transmits it to the heating plate 13. The heating plate 13 receives the signal and inputs the corresponding heat to heat the inner liner 2.

Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand this utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
