The invention provides an electric cooker, which is provided with a cooker body and a cooker cover, wherein the cooker cover of the electric cooker is pivoted on the cooker body and is used for covering and opening the cooker body.
Referring to fig. 1 to 16, solid lines with arrows in the drawings indicate spaces (e.g., holes, cavities, grooves, etc.) or faces, and particularly to fig. 10, in an embodiment of the present invention, a lid of the electric rice cooker includes a lid body 10, a steam valve 20, and an elastic connection member 30.
In this embodiment, referring specifically to fig. 2 and 3, the cover 10 has a steam valve groove 101 and an air outlet hole (not shown) communicating with the steam valve groove 101, and the steam valve 20 is installed in the steam valve groove 101; the elastic connection member 30 is also disposed in the steam valve slot 101, and detachably connects the steam valve 20 with the cover 10, for example, by a snap connection; when the external force is applied to the steam valve 20 to cancel the external force, that is, after the steam valve 20 is pressed and released, the elastic connection member 30 is compressed and then returns to deform, so as to push the steam valve 20 to be separated from the cover 10. The number of the elastic connection pieces 30 may be one or more, so that the single-point bouncing of the steam valve 20 may be realized, or the multi-point bouncing of the steam valve 20 may be realized, or the steam valve 20 may be bounced in a plane direction, and of course, when the number of the elastic connection pieces 30 is more than one, the elastic connection pieces 30 should be uniformly distributed in the steam valve groove 101, so that the bouncing force of the steam valve 20 is balanced. In this embodiment, fig. 1 shows a structure of two elastic connectors 30, and the problem that the two-point bouncing steam valve 20 is inconvenient to coordinate and control due to insufficient elastic force and more than two redundancies is avoided.
In this embodiment, the elastic connection member 30 may be configured to allow the steam valve 20 to be ejected from the steam valve spool 101 in the vertical direction. Since the notch of the steam valve groove 101 is generally oriented vertically upward, the elastic connector 30 is only required to be disposed at the bottom of the steam valve groove 101, and when the user needs to detach the steam valve 20, the user only needs to press the steam valve 20 from top to bottom, so that the steam valve 20 and the cover 10 are separated from each other, and detachment is achieved. Moreover, the cooker body of the electric cooker is contacted with the ground or the working table surface to form a support, so that the electric cooker can not move and is very reliable when the steam valve 20 is pressed. Obviously, this way, it is convenient for the user to apply an external force to the steam valve 20, causing the steam valve 20 to pop up.
In this embodiment, the elastic connection member 30 may be configured to eject the steam valve 20 from the steam valve groove 101 in the horizontal direction. In this structure, the elastic connection member 30 needs to be disposed on one side wall of the steam valve groove 101, and a notch needs to be disposed on a side of the steam valve groove 101 opposite to the elastic connection member 30 for the steam valve 20 to exit the steam valve groove 101 under the elastic thrust of the elastic connection member 30. Of course, an inclined surface may be connected to the bottom surface of the steam valve spool 101, so that the steam valve 20 exits the steam valve spool 101 along the inclined surface under the elastic urging force of the elastic connection member 30.
Referring to fig. 5, when the steam valve 20 is ejected from the steam valve groove 101, a vertical distance H1 between the outer surface of the steam valve 20 and the outer surface of the cover 10 is set to be 13.5mm±7mm. That is, when the steam valve 20 ejects the steam valve groove 101, the height of the steam valve 20 protruding the steam valve groove 101 is equal to the width of the finger, so that the steam valve 20 does not need to be taken out through tool assistance, that is, the user can directly grasp the steam valve 20 by hand, and then the steam valve 20 is conveniently taken off from the cover body 10.

The guiding groove 317 may be a long groove, or may form a V-shaped groove or a W-shaped groove together with the positioning groove 316, which is not limited herein, as long as the positioning post 3143 can slide into the positioning groove 316 and the two clamping arms 3122 can extend out of the accommodating groove 315 to be separated from the limiting part 322, preferably, the positioning groove and the positioning groove together form a W-shaped groove, and the W-shaped groove can avoid the positioning post 3143 from slipping, so as to automatically eject the steam valve 20, thereby improving the reliability of the steam valve 20 after installation.
Further, referring to fig. 1 to 16 in combination with the above-described embodiments, the mounting and removal process of the steam valve 20 will be briefly described:
when the steam valve 20 is installed, the steam valve 20 is placed in the steam valve groove 101, the limiting part 322 and part of the connecting part 321 of the steam valve 20 are inserted between the two clamping arms 3122 of the elastic push button 31, when the steam valve 20 is pressed down, the steam valve 20 transmits thrust to the body 3121 of the elastic push button 31 through the connecting part 321 and the limiting part 322, so that the body 3121 slides downwards and drives the two clamping arms 3122 to enter the accommodating groove 315 along with the body 3121, and the two clamping arms 3122 are pressed by the groove walls of the accommodating groove 315 to be relatively close; meanwhile, the body 3121 also transmits pressure to the return spring 313 through the rotating shaft 3142, so that the return spring 313 is compressed, a reaction force is generated when the return spring 313 is compressed to act on the rotating shaft 3142, so that the connecting rod 3141 swings around the rotating shaft 3142 and drives the positioning column 3143 to slide in the guide groove 317, when the positioning column 3143 slides from the second sliding position to the third sliding position, the positioning column 3143 is limited by the third sliding position and cannot slide downwards, that is, the return spring 313 cannot be compressed any more, at the moment, the steam valve 20 is released, and the return spring 313 returns to elastic deformation to apply a reaction force to the rotating shaft 3142, so that the positioning column 3143 slides upwards to the first sliding position and is limited in the positioning groove 316. Since the positioning column 3143 is limited by the positioning groove 316, the return spring 313 cannot recover the elastic deformation, at this time, the two clamping arms 3122 firmly clamp the limiting portion 322 of the fastening member 32 under the extrusion of the groove wall of the accommodating groove 315, so as to limit the separation of the steam valve 20 from the cover 10, so that the steam valve 20 is reliably fixed in the steam valve groove 101, and the installation of the steam valve 20 is realized.
When the steam valve 20 needs to be disassembled, the steam valve 20 is pressed downwards, at this time, the steam valve 20 transmits thrust to the body 3121 of the elastic push button 31 through the connecting part 321 and the limiting part 322, so that the body 3121 continues to slide downwards, and the return spring 313 continues to compress, meanwhile, the body 3121 drives the connecting rod 3141 and the positioning column 3143 to slide towards the left lower part or the right lower part of the positioning groove 316, that is, the positioning column 3143 slides from the first sliding position to the third sliding position at this time, so that the return spring 313 can continue to compress, when the pressing force applied to the steam valve 20 disappears, the return spring 313 resumes the reverse thrust generated by deformation to act on the rotating shaft 3142 of the positioning piece 314, so that the positioning column 3143 of the positioning piece 314 slides in the guiding groove 317, at this time, under the elastic thrust of the return spring 313, the positioning column 3143 of the positioning piece 314 slides towards the second sliding position at the third sliding position of the guiding groove 317, and pushes the body 3121 to slide upwards, so that the two clamping arms 3122 on the body 3121 extend out of the accommodating groove 315, and the release part 32 is separated from the buckling part 322, namely, the valve is disassembled, and the valve is disassembled;
referring to fig. 15, the vertical distance H2 between the second sliding positions of the third sliding is 13.5mm±7mm, that is, the maximum deformation amount of the return spring 313 is 13.5mm±7mm, so as to ensure that the steam valve 20 can be ejected from the steam valve groove 101 after being under the elastic force of the return spring, and the vertical distance between the outer surface of the ejected steam valve 20 and the outer surface of the cover 10 is 13.5mm±7mm. The user can conveniently grasp the steam valve 20 by hand, and the steam valve 20 can be conveniently taken out from the cover body 10.
In addition, it should be noted that, because the electric cooker of the present invention adopts all the technical schemes of all embodiments of the cover of the electric cooker, all the beneficial effects brought by the technical schemes of the embodiments of the electric cooker of the present invention corresponding to the cover of the electric cooker are not described in detail herein.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
