Detailed Implementation

[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figure 1 , Figure 2 As shown, a specific embodiment of the present invention discloses an IH electromagnetic rice cooker, including a lid 100, a tray 200 mounted on the bottom of the lid 100, and a sealing ring 300 provided below the tray 200. The sealing ring is detachably mounted on the lid. Figure 3 , Figure 7 As shown, a first vent 210 and a second vent 220 are fixedly provided on the inner bottom wall of the tray 200; the first vent 210 has a first vent 211 penetrating the bottom surface of the tray, and a first vent pipe 212 extending out of the pot lid is provided on the first vent 211, with the first vent pipe 212 communicating with one side of the first vent 211; the second vent 220 has a second vent 221 penetrating the bottom surface of the tray, and a second vent pipe 222 communicating with one side of the second vent 221 is provided on the second vent 220, with the second vent pipe 222 communicating with one side of the second vent 221. The other end is connected to the air inlet of the air pump 400, and the air outlet of the air pump 400 is connected to a third air pipe 410 extending outside the pot lid; a first sealing component 500 is provided at the first exhaust component 210, which can be adjusted to change the open / closed state of the first air pipe and the first air hole; a second sealing component 600 is provided at the second exhaust component 220, which can be adjusted to change the open / closed state of the second air pipe and the second air hole; an adjustment device 700 is installed on the tray 200 for adjusting the first sealing component 500 and the second sealing component 600.

[0038] The aforementioned IH electromagnetic rice cooker has a detachable sealing ring mounted on the lid for easy cleaning and subsequent individual replacement.

[0039] Its first vent and first vent tube serve as the main exhaust section. When cooking does not require sealing, this section is in a normally open state, maintaining normal exhaust. When cooking requires sealing or when air extraction is needed, the first sealing component can be adjusted to seal this section. It can be adjusted according to actual needs.

[0040] The second vent and the second air tube are used for active venting. The second sealing component is normally closed to maintain the seal and prevent liquid or food impurities from entering the air pump during cooking, thus avoiding easy damage. When active venting is needed, the second sealing component can be adjusted to release the seal and achieve on-demand adjustment.

[0041] The first blocking assembly and the second blocking assembly share the same adjusting device, which can reduce the use of the electric driving element, reduce the cost, and reduce the space occupation, so that the structure is more compact.

[0043] Further, the communication part of the first air pipe and the first air hole is inclined, and inclines downward from the bottom end of the first air pipe to the first air hole. This part is used as the main exhaust part. During the normal cooking process, this part may need to be in the open state, which means that the internal liquid or food debris may enter the inside or even overflow. However, the above structure design can facilitate cleaning the inside, and the inside of the first air pipe at the top of the pot cover can be cleaned, and a soft brush can be inserted for cleaning when necessary.

The side of the bottom of the pot cover close to the pot body is provided with a clamping groove, and the side away from the pot body is provided with a pressing buckle, the rod can be adaptively clamped in the clamping groove, and the buckling plate is buckled and connected to the pressing buckle, so that the sealing ring is used as a structure component that can be separately disassembled, facilitating disassembly and cleaning. When the pot cover is closed in place, the sealing rings between the sealing ring and the bottom surface of the tray and between the sealing ring and the top edge of the inner pot are extruded, thereby forming an effective sealing effect. It should be noted that the detachable sealing element is common in the field of rice cookers, and details are not described.

[0061] Further, the pressing strip 712 is a 3 / 4 circular ring structure, the starting end of the pressing strip is located away from one end of the second air hole, and the first guide surface is arranged at the starting end of the pressing strip; when the convex block 533 abuts at the first guide surface 713 and the bottom surface of the front end area of the pressing strip 712, the frame rod 614 is located in the first smooth section 7231; when the frame rod 614 is located at the lifting section 7232 and the second smooth section 7233, the convex block 533 is located at the bottom surface of the pressing strip 712; the structure is limited, and different angles can be rotated through the adjusting device, so that the open and closed cooperation states of the first sealing assembly and the second sealing assembly are realized;

[0062] If only the first air hole and the first air pipe need to be conducted, the second air hole is in a sealing state; this is the initial state of the adjusting device, at this time, the convex block can abut against the bottom surface of the rotating disc, close to one side of the first guide surface; the frame rod is located at the first smooth section;

[0063] If the first air hole and the second air hole need to be in a sealing state, the convex block can be adjusted to abut against the bottom surface of the pressing strip, and the frame rod is located at the first smooth section;

[0064] If the first air hole needs to be sealed, the second air hole and the second air pipe need to be conducted, the convex block can be adjusted to abut against the bottom surface of the pressing strip, and the frame rod is located at the second smooth section;

[0065] According to different needs, different angles can be rotated through the motor to meet the corresponding open and closed combination.

[0066] Further, the temperature sensor and the pressure sensor are installed on the tray, the probes of the temperature sensor and the pressure sensor pass through the bottom surface of the tray and extend into the interior of the pot body, and sealing treatment is performed at the connection position, so that the internal temperature and the air pressure can be monitored in real time; it should be noted that the above two sensors are common electrical devices and are also commonly used in the field of electric rice cookers, and details are not described herein;

[0079] B4, after the air release is completed, the above preservation method is started again;

[0080] It should be pointed out that if the internal pressure is higher than the preset range, the B3 step needs to be started to actively release air and reduce pressure, thereby improving the use safety.
