An inner pot of an electric cooker, which is suitable for the electric cooker; a baffle ring 7 is fixedly connected to an opening of the outer side wall of the inner pot, the baffle ring 7 is annular, and the width of the baffle ring is close to that of the upper end of the heat collecting sleeve 1; the upper end surface of the baffle ring 7 is flush with the upper end surface of the inner pot, and the lower end surface of the baffle ring is abutted against the upper end surface of the heat collecting sleeve 1; during operation, place in gathering hot set 1 when interior pot, the terminal surface is contradicted with gathering the up end laminating of hot set 1 under the fender ring 7, and when cooking, the steam in the cavity 11 just is difficult for escaping from the gap of interior pot upper end and gathering hot set 1, has improved the gas tightness, and then can utilize the heat of steam more fully, further improves this electricity rice cooker energy-conserving heat retaining effect.
The specific process is as follows:
when the cooker works, the heating disc is arranged in the cooker body, and when the inner pot is placed in the cooker body, the heating disc is just in contact with the lower end face of the inner pot; the steam generated in the heating process is guided and gathered in the cavity 11 through the vent groove 5 and the connecting groove 4, the heat carried by the steam heats the inner pot, and when the heating plate reaches the tripping temperature of cooking, the heating plate stops working; the redundant gas or steam in the heat collecting sleeve 1 is discharged through the gas outlet hole 13 and the mounting groove 6; the heat carried by the steam is not completely lost, is gathered in the heat gathering sleeve 1 and is fully utilized, and the heat is transferred to the inner pot to keep the temperature of the inner pot continuously; because the heat loss is slow, the temperature inside and outside the inner pot is similar and the descending range is low in the heat preservation process; when the inner pot is just placed on the heating disc, the inner side wall of the sealing ring 8 is clamped in the sealing groove 9, and small extrusion is formed on the groove wall of the sealing groove 9; steam in the connecting groove 4 directly enters the cavity 11 through the internal thread sleeve 16 and the external thread sleeve 15, and the air outlet 13 is communicated with the guide groove 611 through the pipe sleeve 17, so that the steam is further prevented from flowing out between the heat collecting sleeve 1 and the cooker body; when the electric cooker is not in operation, the heat-insulating cover is opened and the inner pot is taken out, then the internal thread sleeve 16 is manually rotated to be separated from the external thread sleeve 15, the heat-collecting sleeve 1 is manually lifted to be taken out from the cooker body, and meanwhile, the pipe sleeve 17 is also separated from the guide groove 611, so that the heat-collecting sleeve 1 is cleaned or replaced; when the cooker works, a part of gas in the cavity 11 enters the guide groove 611 through the air outlet hole 13 and the pipe sleeve 17, at this time, the sealing plate 62 and the inner side wall of the guide groove 611 are in a sealing state, and the air pressure in the guide groove 611 is gradually increased and reaches a state that the pressure spring 63 is not enough to support the sealing state between the sealing plate 62 and the groove wall of the guide groove 611, the gas in the guide groove 611 overcomes the pressure of the pressure spring 63 at one side of the sealing plate 62 under the action of the air pressure to open the sealing plate 62, and is discharged to the ambient environment outside the cooker body from the gap between the sealing plate 62 and the groove wall of the guide groove 611, at this time, the air pressure in the inner cooker is higher than the ambient atmospheric pressure, and then the food is more easily cooked; meanwhile, the steam in the cavity 11 is finally condensed into liquid water which falls on the bottom of the heat collecting sleeve 1 and flows into the guide groove 611 along the air outlet 13 and begins to extrude the sealing plate 62, and as can be seen from a pressure formula P ═ ρ gh, when the water level in the guide groove 611 reaches the height of the orifice of the air outlet 13, the pressure on the side, far away from the pressure spring 63, of the sealing plate 62 overcomes the pressure on the side, close to the pressure spring 63, of the sealing plate 62, so that the sealing plate 62 is opened and the liquid water flows out; when the inner pot is placed in the heat collecting sleeve 1, the lower end face of the baffle ring 7 is abutted to the upper end face of the heat collecting sleeve 1 in a fitting manner, and steam in the cavity 11 is not easy to escape from a gap between the upper end of the inner pot and the heat collecting sleeve 1 during cooking.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
