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 18, 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 slot 101 and an air outlet hole 102 communicating with the steam valve slot 101, the steam valve 20 is installed in the steam valve slot 101, and the lower part of the steam valve 20 is in sealing fit with the air outlet hole 102; 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. When the elastic connecting piece 30 connects the steam valve 20 with the cover 10 in a snap-fit manner, after the elastic connecting piece 30 recovers the deformation, the elastic connecting piece 30 firstly unbuckles the steam valve 20 with the cover 10, then pushes the steam valve 20 to disengage from the cover 10, and makes the steam valve 20 pop out from the steam valve slot 101 along the vertical direction. 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 double-point bouncing of the steam valve 20 may be realized, or the steam valve 20 may be bounced in a plane direction, however, 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 is configured to eject the steam valve 20 from the steam valve groove 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.
It should be noted that, the steam valve 20 can be taken out by the user conveniently by loosening with the steam valve groove 101 under the elastic thrust of the elastic connecting piece 30, rather than necessarily needing to pop out from the steam valve groove 101, and of course, in this embodiment, in order to better take the steam valve 20, the gravity center position of the steam valve 20 and the position of the projection of the elastic connecting piece 30 on the same horizontal plane are staggered, the lever principle is utilized, the gravity center position of the steam valve 20 is used as a fulcrum by using the elastic connecting piece 30 as power, and one end of the steam valve 20 is sprung up, so that when the steam valve 20 is popped up by the elastic connecting piece 30, the steam valve 20 can be turned over to one side of the gravity center position to facilitate taking, and the steam valve 20 can be conveniently taken out without setting a buckling position. Optionally, the steam valve 20 is provided with a weight (not shown) to form the gravity center, and the weight may be a component fixed on the steam valve, such as a steel block, an iron bead, or the like, or a relatively heavy material, such as steel, iron, copper, ceramic, or the like, is used at a corresponding position of the steam valve 20, or the thickness of the plate material of the steam valve 20 is increased at a corresponding position of the steam valve 20 to increase the weight, and in the embodiment shown in fig. 18, the gravity center is located on the Z line in fig. 18.
In this embodiment, as further described with reference to fig. 17 and 18, when the number of the elastic connectors 30 is two and the steam valve 20 is symmetrically disposed about the air outlet 102, the positions of the center of gravity of the steam valve 20 projected on the horizontal plane where the two elastic connectors 30 are located at both sides of the connecting line segment between the two elastic connectors 30 and are located on the horizontal middle line between the two elastic connectors 30; further, it is preferable that a horizontal center line of the line connecting the two elastic connection members 30 coincides with a center line L1 of the front and rear ends of the cover 10. The horizontal center line passes through the center of the radial section of the outlet hole 102. In this structure, the steam valve 20 takes the center of gravity as a fulcrum, and the other side adopts two elastic connecting pieces 30 to provide balanced elastic thrust, so that the steam valve 20 is turned over, and the user can grasp conveniently.
In addition, when the number of the elastic connecting pieces 30 is three or more, the position of the gravity center of the steam valve 20 projected on the horizontal plane where a plurality of (three or more) elastic connecting pieces 30 are located is not in the largest area of the closed area surrounded by the elastic connecting pieces 30, so that the coincidence of the gravity center of the steam valve 20 and the center point of the thrust generated by the elastic connecting pieces 30 is avoided, and the steam valve 20 is pushed to turn on one side by the elastic connecting pieces 30 after each trip, so that the user can conveniently grasp the steam valve. In addition, in order to further facilitate the disassembly and grabbing of the steam valve 20 by a user, the rear end of the steam valve 20, which is close to the pivot joint of the pot cover and the pot body of the electric cooker, can be provided with a handle for conveniently disassembling the steam valve 20, so that the gravity center of the steam valve 20 and the projection position of the elastic connecting piece 30 on the same horizontal plane are further away from the rear end of the steam valve 20, and after each time the steam valve 20 is disassembled, the steam valve 20 is pushed to turn over by the elastic connecting piece 30, and the rear end of the steam valve 20 is lifted upwards under the supporting action of the elastic connecting piece 30, thereby facilitating the grabbing and improving the user experience.
