Description

Technical Field

[0001] This utility model belongs to the technical field of electric rice cooker cooking appliances, and in particular relates to an intelligent electric rice cooker that prevents burns. Background Technology

[0002] Existing rice cookers, after cooking rice, retain heat by releasing steam very slowly from the inner pot. This creates a problem: when a user opens the lid to scoop out rice, the steam rushes out instantly, easily causing burns. To address this, a smart rice cooker with anti-scalding functionality is proposed. Summary of the Invention

[0003] The present invention provides a smart rice cooker that prevents burns.

[0004] This utility model is achieved through the following technical solution: it includes a shell, an inner liner, and a cover hinged to the top of the shell. A control panel is provided on the shell or the cover. At least two lifting components are provided on the upper circumference of the shell's interlayer. A lifting ring adapted to the inner liner is provided on the top inner side of the shell. The lifting ring connects to each lifting component. The protruding upper edge of the inner liner presses against the lifting ring. A vent hole is provided on the top of the cover. A vent fan is coaxially arranged in the vent hole through a frame, and the vent hole and the vent fan are spaced apart. A vent cover is provided at the outer port of the vent hole. A steam permeable valve plate adapted to the vent hole is provided at the inner port of the vent hole. A valve drive is provided on the cover on either side of the vent hole. The valve drive is connected to the steam permeable valve plate and controls the opening and closing of the vent hole. The lifting components, the steam permeable fan, and the valve drive are electrically connected to the control panel.

[0005] The beneficial effects of this utility model are as follows: It improves upon existing smart rice cookers by adding a function to lift the inner pot during cooking. It also improves the steam vent of existing smart rice cookers, allowing for adjustment of the vent's opening and closing size. During cooking, the steam vent is reduced by adjusting the steam valve plate, allowing steam to escape before serving rice, effectively preventing burns from the high temperature of the inner pot. Furthermore, to facilitate removing the inner pot containing rice, a lifting mechanism and ring lift the upper edge of the inner pot out of the outer shell, making it easier for users to remove and preventing burns caused by removing the inner pot while it is still attached to the shell.

Detailed Implementation

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the specific embodiments are described in detail below with reference to the accompanying drawings.

[0015] like Figures 1-6 The scalding-proof smart rice cooker shown includes a shell 1, an inner pot 2, and a lid 3 hinged to the top of the shell 1. A control panel 4 is provided on the shell 1 or lid 3. At least two lifting components 5 are provided on the upper circumference of the interlayer of the shell 1. A lifting ring 6 adapted to the inner pot 2 is provided on the inner top of the shell 1. The lifting ring 6 connects to each lifting component 5. The protruding upper edge of the inner pot 2 presses against the lifting ring 6, so that the lifting ring 6 supports the upper edge of the inner pot 2. When the lifting components 5 drive the lifting ring 6 to rise and fall, the inner pot 2 moves up and down accordingly. A steam vent 7 is provided on the top of the lid 3, and a steam exhaust fan is coaxially installed in the steam vent 7 through the frame. 11, and the steam vent 7 and the steam vent fan 11 are spaced apart. A steam vent cover 10 is provided at the outer port of the steam vent 7. The steam vent cover 10 is provided with a steam outlet. A steam permeable valve plate 15 is provided at the inner port of the steam vent 7. A valve drive component 16 is provided on the cover 3 on either side of the steam vent 7. The valve drive component 16 is connected to the steam permeable valve plate 15 and controls the opening and closing of the steam vent 7 and adjusts the opening degree of the steam vent 7. The lifting component 5, the steam vent fan 11, and the valve drive component 16 are electrically connected to the control panel 4 of the rice cooker. The lifting component 5, the steam vent fan 11, and the valve control switch are added to the control panel 4.

[0016] Furthermore, to enhance the adjustment flexibility of the steam valve plate 15, the valve control switch is equipped with at least four buttons: a closed / fully open button, a quarter-open button, a third-open button, and a half-open button. By pressing different buttons as needed, the steam valve plate 15 will adjust the opening degree of the exhaust port 7, thereby adjusting the exhaust volume and exhaust speed.

[0017] The upper part of the interlayer of the housing 1 is provided with a receiving groove that matches each lifting component 5. The lifting component 5 is installed in the receiving groove. A cover plate 19 is provided on the top of the receiving groove. The cover plate 19 is provided with a through hole that matches the lifting component 5. The lifting component 5 is a cylinder or a hydraulic cylinder. Its piston rod passes through the through hole of the cover plate 19 and connects to the lifting ring 6. A coaxial sealing ring 20 that matches the piston rod is provided in the through hole to prevent water vapor from entering the receiving groove from the through hole and contacting the lifting component 5, while not interfering with the movement of the lifting component 5.

[0018] The exhaust port 7 is connected and combined with the installation section 8 and the working section 9 to form a convex structure. The body of the exhaust fan 11 is installed in the installation section 8 through the frame, the fan blade is located in the working section 9, and the steam valve plate 15 is located at the lower port of the working section 9.

[0019] The frame is composed of a vertical cylinder 12 and an annular plate 13 connected in a T-shape. It is secured to the lower part of the exhaust port 7 via the annular plate 13. The exhaust fan 11 is installed in the vertical cylinder 12 of the frame and extends downwards through the annular plate 13 into the working section 9 of the exhaust port 7. Furthermore, to ensure sealing and prevent interference with the operation of the exhaust fan 11, a coaxial sealing ring 20 is provided between the shaft of the exhaust fan 11 and the annular plate 13. The vertical cylinder 12 protects the exhaust fan 11 body, preventing water vapor from directly contacting the exhaust steam. To reduce the damage rate, the fan 11 body has steam vents 14 on the ring plate 13 outside the vertical cylinder 12. The steam vents 14 connect the installation section 8 and the working section 9. Water vapor in the inner liner 2 enters the gap between the vertical cylinder 12 and the inner wall of the exhaust hole 7 through the steam vents 14 and flows upward, and finally exits from the exhaust cover 10, ensuring that water vapor can be discharged normally. On the other hand, the frame and coaxial sealing ring 20 prevent substances in the exhaust fan 11 from falling into the inner liner 2, ensuring the hygiene and safety of the rice.

[0020] The valve drive component 16 is a motor. The motor's rotating shaft extends downward through the cover 3 and connects to the steam valve plate 15. The motor drives the steam valve plate 15 to rotate, and a coaxial sealing ring 20 is provided between the rotating shaft and the cover 3.

[0021] The outer or inner wall of the receiving groove is provided with a heat insulation layer 17 to protect the lifting component 5.

[0022] The inner top of the shell 1 is provided with a stepped support 18 that matches the lifting ring 6. The lifting ring 6 is placed on the support 18 so that the lifting ring 6 is flush with the inner top of the body, ensuring the stability of the inner pot 2 and preventing the lifting ring 6 from being higher than the top of the shell 1, which would cause the sealing ring inside the lid 3 to be unable to effectively seal the edge of the inner pot 2 when the rice cooker is cooking rice.

[0023] The working principle of this invention is as follows: When cooking rice, the inner pot 2 containing rice is placed into the outer shell 1, with the protruding upper edge of the inner pot 2 pressing against the lifting ring 6. The lid 3 is then closed, and the rice cooker is started via the control panel 4. During cooking, the valve control switch activates the valve drive 16, which drives the steam permeable valve plate 15 and the working section 9 of the steam vent 7 to adjust the amount of steam discharged. After cooking, when it is necessary to open the lid 3 to empty the rice, the valve control switch first activates the valve drive 16, which drives the steam permeable valve plate 15 to open the working section 9 of the steam vent 7 to its maximum. Then, the exhaust fan 11 is activated to quickly extract and discharge the steam accumulated in the inner pot 2. Finally, the lid 3 is opened. When it is necessary to remove the inner pot 2 containing rice, the lifting component 5 is activated, causing the lifting ring 6 to rise, thus lifting the upper part of the inner pot 2 out of the outer shell 1. After removing the inner pot 2, the lifting component 5 is controlled to lower the lifting ring 6 back to its original position.
