Example two
Referring to fig. 4-6, the vacuum rice cooker of the present embodiment is provided with a steam valve 500 on an inner lid 220, the steam valve 500 and the inner lid 220 are assembled and disassembled as a single component, the steam valve 500 cannot be forgotten to be cleaned while the inner lid 220 is cleaned, because the vacuum rice cooker needs to be sealed in a cooking cavity by vacuum pumping and negative pressure cooking, a push rod 510 needs to be provided on the steam valve 500, the push rod 510 can control the on-off of the steam valve 500, an electromagnetic valve 600 for driving the push rod 510 to act is provided on an upper lid 210, when the negative pressure cooking is performed, the electromagnetic valve 600 drives the push rod 510 to move towards the inside of the steam valve 500 to block a steam passage in the steam valve 500, and after the electromagnetic valve 600 is powered off, the push. If the amount of movement of the inner lid 220 relative to the upper lid 210 is too great, the push rod 510 of the steam valve 500 may be deviated from the driving range of the solenoid valve 600, and vacuum pumping and negative pressure cooking may not be reliably achieved.
In view of the above problems, the inner side of the upper cover 210 of the present embodiment has a cavity 211 for accommodating the inner cover 220, the cavity 211 is internally provided with a limit post 214 for radially limiting the inner cover 220, a gap of 0.1mm to 0.4mm is formed between the limit post 214 and the inner cover 220, the arrangement of the limit post 214 limits the amount of movement of the inner cover 220 in the plane direction thereof, if the gap between the limit post 214 and the inner cover 220 is smaller than 0.1mm, the inner cover 220 is easily interfered by the limit post 214 when being disassembled and assembled, and is not convenient to operate; if the gap between the position-limiting column 214 and the inner cover 220 is larger than 0.4mm, the movement of the inner cover 220 in the cavity 211 is too large, and for the vacuum electric cooker, the inner cover 220 with too large movement easily causes the push rod 510 on the steam valve 500 to deviate from the driving range of the electromagnetic valve 600, and thus the vacuum pumping and negative pressure cooking cannot be realized, so the gap between the position-limiting column 214 and the inner cover 220 is limited to be 0.1 mm-0.4 mm, and is preferably 0.2mm, and in other embodiments, the gap values such as 0.1mm, 0.15mm, 0.25mm, 0.3mm, and 0.4mm can be selected according to the actual situation.
In order to realize the detachable installation of the inner lid 220, in the present embodiment, the insertion slot 213 and the inner lid lock catch 212 are respectively disposed on two opposite sides of the cavity 211, the insertion portion 227 matching with the insertion slot 213 extends from one side of the inner lid fixing frame 222, the insertion portion 227 is inserted into the insertion slot 213, and the other side of the inner lid 220 is locked by the inner lid lock catch 212, because the movement amount of the inner lid lock catch 212 is large, the locking side of the inner lid 220 is easy to shake, for this reason, the distribution position of the limiting posts 214 is optimized in the present embodiment, as can be seen from fig. 4, two limiting posts 214 are symmetrically disposed at the position of the cavity 211 close to the locking side of the inner lid 220, and the two limiting posts 214 are not in the same diameter direction of the inner lid 220, on one hand, the inner lid 220 can be limited in multiple directions by using a small number of the limiting posts 214, such as the width direction and the length direction, the locking side of the inner cover 220 is prevented from greatly shaking, the inner cover inserting part 227 is limited by the matching slot 213, the circumferential uniformity of the inner cover 220 is realized, and the overall shaking amount of the inner cover 220 is greatly reduced. In other embodiments not shown in the present invention, according to actual conditions, the limiting columns may be provided in pairs in two groups, three groups, or the like, and may be distributed uniformly along the circumferential direction of the cavity.
In order to better limit the inner cover 220, after the insertion part 227 is inserted into the insertion slot 213, a gap of 0.1mm to 0.4mm is formed between the insertion part 227 and the side wall of the receiving cavity. If the gap between the insertion part 227 and the side wall of the cavity is smaller than 0.1mm, the fit gap between the insertion part 227 and the slot 213 is too small, which is inconvenient for the inner lid 220 to be disassembled and assembled, and if the gap between the insertion part 227 and the side wall of the cavity is larger than 0.4mm, the movement of the insertion side of the inner lid 220 is too large, which also easily causes the push rod 510 on the steam valve 500 to deviate from the driving range of the electromagnetic valve 600, and the vacuum pumping and negative pressure cooking cannot be realized, so that the gap between the insertion part 227 and the side wall of the cavity is limited to be 0.1 mm-0.4 mm, and most preferably 0.2mm, and in other embodiments, the gap values such as 0.1mm, 0.15mm, 0.25mm, 0.
