Description

Lid opening and closing device of electric insulation pressure cooker

The present invention relates to a lid opening and closing device of the electric thermal pressure cooker, in particular to allow the lid to be automatically opened and closed by the stationary motor and at the same time to prevent the pressure packing to be pulled to one side during the opening and closing operation, as well as to improve the reliability of the product. It relates to a lid opening and closing device of an electric thermal pressure cooker.

In general, the electric thermal pressure cooker used at home is capable of performing the cooking in a high temperature and high pressure atmosphere for the cooking object loaded in the rice cooker using electric energy. When the lid is closed for the inner container, airtightness is required to maintain the state of high temperature and high pressure, and for this purpose, an opening and closing device that can be easily opened and closed with the inner rice cooker is required.

Therefore, conventionally, the lid opening and closing device of the electric thermal pressure cooker capable of meeting the requirements as described above has been filed by the present applicant (Utility Model Registration Application No. 91-14994).

Looking at the configuration of the lid opening and closing device of the electric thermal pressure cooker briefly, the conventional lid opening and closing device is provided with an inner cooker having a plurality of engaging protrusions arranged at regular intervals on the upper outer periphery, the rotating body is provided with a locking projection of the inner cooker It has a configuration in which a plurality of locking projections and handles are formed on the bottom with the same spacing.

The lid opening and closing device of the conventional electric thermal pressure cooker configured as described above rotates the handle in one direction, so that the rotating body rotates. Accordingly, when the locking protrusion of the rotating body and the locking protrusion of the inner rice cooker overlap each other, the closing operation of the lid is made, When rotating in the opposite direction, the locking protrusion of the rotating body and the locking protrusion of the inner rice cooker were separated, thereby opening the lid.

However, such a conventional lid opening and closing device to realize the opening and closing operation of the lid while the user grasps the handle and rotates the rotating body one by one, there is not only the inconvenience of rotating the handle to the left and right one by one when the lid is opened and thus coupled to the inner lid Pressure packing tends to drift to one side, which greatly reduces the quality of the product.

In addition, since the handle is exposed to the side of the main body, it is easily brought into contact with other products, causing a problem in that the appearance or appearance is not beautiful.

The present invention was devised to solve the problems of the prior art, and its purpose is to automatically open and close the lid by the stationary motor and at the same time to prevent the pressure packing from being pulled to one side during the opening and closing of the product. It is to provide a lid opening and closing device of the electric thermal pressure cooker to improve the reliability.

The present invention as a means for achieving the above object is a stationary motor for driving the drive gear is powered when the on-off switch formed on the microcomputer "on", and is engaged between the drive gear and the operating gear and the drive gear is driven A connecting gear for rotating the operation gear for a certain period by receiving the driving force, and one end is connected to the operation gear and the other end is connected to the opening and closing end when the operating gear rotates and is pulled to the front along the guide tube and lifts the opening and closing end at the same time. The main feature of the technical configuration is that the wire is separated from the flange portion of the inner pot, and a fixed end fixed to the inner pot and the hinge is coupled to the opening and closing end so that the opening and closing end is lifted by the pulling action of the wire.

(Example)

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a side cross-sectional view showing a state in which the lid opening and closing device according to the present invention is installed, Figure 2 is a plan view showing a lid closed by the lid opening and closing device according to the present invention, Figure 3 is a lid opening and closing device according to the present invention Is a plan view showing a state in which the lid is opened.

The present invention is a driving means for opening and closing the lid 83, as shown in Figures 1 to 3, when the "on" the opening and closing switch (not shown) formed in the microcomputer is applied power to drive the drive gear 20 When the gear is engaged between the stationary motor 10 and the driving gear 20 and the operating gear 40 and the driving gear 20 is driven, the connecting gear 30 receives the driving force to rotate the operating gear 40 for a predetermined period. Is mobilized.

Wherein the microcomputer is to control the function of the electric thermal pressure cooker, the on / off switch for electrically "on", "off" the stationary motor 10 to the microcomputer side is electrically connected, the open / close switch is a technology that normally works The description is omitted because it is a content.

As a device for opening and closing the lid 83 is connected to the operating gear 40 and the other end is connected to the opening and closing 70, when the operating gear 40 is rotated and pulled to the front along the guide tube 50 and at the same time Opening and closing end 70 so that the opening and closing end 70 can be lifted by the wire 60 to separate the flange portion 81 of the inner pot 80, and the pulling operation of the wire 60. ) And hinge 71 is coupled to the fixed end 72 is fixed on the inner pot lid (82).

When the lid opening and closing device of the present invention configured as described above is coupled to the electric thermal pressure cooker, the connection gear 30 and the operation gear 40 are connected to the drive gear 20 formed in the stationary motor 10 as shown in FIGS. 1 and 2. In order to be engaged in order, one end of the wire 60 is connected to the operating gear 40 and the other end is connected to the opening and closing end 70 is coupled to the flange portion 81 of the inner pot 80, fixed End 72 is coupled to the opening and closing end 70 and the hinge 71 is coupled to the standby state that the opening and closing end 70 can be lifted when the wire 60 is pulled.

When the lid 83 is to be opened in the state in which the lid 83 is closed to the main body as described above, first, when the on / off switch formed in the microcomputer is "on", the stationary motor 10 is driven as shown in the arrow direction of FIG. 2. ) Is driven in the counterclockwise direction, and the connecting gear 30 that receives the driving force of the driving gear 20 rotates the operating gear 40 for a predetermined period.

At this time, since one end of the wire 60 is connected to the operation gear 40 and the other end is connected to the opening and closing end 70, respectively, when the operation gear 40 rotates, it is pulled to the front along the guide tube 50, and thus The closed end 70 is lifted from the fixed end 72 around the hinge 71 and separated from the flange portion 81 of the inner pot 80 so that the lid 83 can be opened.

Contrary to the above, when the switch 83 is turned off to close the lid 83, the forward and reverse motor 10 rotates in the clockwise direction as shown by the arrow in FIG. Therefore, the wire 60 is pushed downward along the guide tube 50, the opening and closing end 70 is rotated about the hinge 71 by the wire 60 is pushed to the flange portion of the inner pot 80 ( 81, the lid 83 is closed.

As described above, according to the present invention, since the wire is pushed and pulled according to the left and right rotation directions of the stationary motor, the opening and closing operation of the lid is automatically performed, and the pressure packing is prevented from being pulled to one side during the opening and closing operation. The effect is that the reliability of the product can be improved.

The present invention has been described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and should be made by those skilled in the art to which the present invention pertains without departing from the gist of the present invention. Various changes and modifications can be made.
