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, and more particularly, in the apparatus for automatically opening and closing the lid by the power supply of the electric thermal pressure cooker to open and close the lid manually even when the power is turned off. It relates to a lid opening and closing device.

In general, the electric insulation pressure cooker is cooked by electric energy by inserting a cooking object into the inner rice cooker, it is an absolute requirement to properly adjust the pressure and temperature of the inner rice cooker, and to solve this, the airtightness of the lid and the main body depends.

In the related art, since the airtightness is required, many devices related to opening and closing the lid of the electric thermal pressure cooker have been introduced and developed.

If you look at this roughly can be distinguished from manual and automatic, manual can open and close the lid to ensure the user's trust, but there is a problem that can not revival in the high quality of the product, and also automatically open and close the electric pressure cooker The high quality can be expected, but when the power is cut off, most of the gear system is adopted, so it may be damaged by applying excessive force to the geared part. In some cases, the contents of the internal rice cooker should be discarded. This problem caused a decrease in the reliability of the product.

Therefore, the present invention has been devised to solve the above-mentioned problems. The present invention adopts a method of automatically opening and closing the lid when electricity is supplied and manually opening and closing the lid when electricity is cut off, thereby improving the reliability of the product. It is

The present invention is a means for solving the above object, the drive means electrically connected to the microcomputer and the top of the lid bottom body, and rotates to receive the driving force of the drive means is formed in the upper transmission gear and the supply / cutoff of electricity A clutch formed with a disk to be in close contact with the separated / separated, the lever A is engaged with the transmission gear to one side of the linear movement, and one side is fixed to the rotation with the lever A, the other side is fixed with the fixed rod protruding to the rotating body and the stop portion It is composed of a configuration to open and close the lid by rotating the rotating body by the circular motion to the center.

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

EXAMPLE

Figure 1 is an exploded perspective view of the main part of the present invention, Figure 2 is a perspective view of the combined idea of the present invention, Figure 3 is a plan view showing the operation of the present invention, (a) is a lid closed state (b 4) is a side configuration diagram of the main part of the present invention, (a) is a state in which the disc is in close contact with the clutch main body by supply of electricity, and (b) is a disc in the clutch by the interruption of electricity. The state separated from the main body is shown.

The upper outer periphery of the inner rice cooker 10 is loaded with a plurality of engaging projections 11 are formed at regular intervals, and the locking projections 21 in the rotating body 20 in a structure corresponding to the engaging projections 11. ) Is formed and the handle 22 for manually opening and closing the lid is configured on one side.

A lid bottom 30 is formed on the rotary body 20 and a driving means 40 electrically connected to the microcomputer is provided on the lid bottom 30. The drive means 40 is a clutch in which the drive motor 41, the drive gear 42 connected to the drive motor 41, and the gear part 54 receiving the driving force of the drive gear 42 are formed on the outer circumference. It consists of 50.

In addition, the clutch 50 is one side of the lever A (60) which is in close contact with the disk 52, the transmission gear 53 is formed on the upper side by the supply / interruption of electricity, the linear movement to the transmission gear (53) This consisted of a mating configuration.

One side is rotatably fixed to the lever A (60) and the other side is formed with a long groove (71) is fixed to the fixing rod 23 protruding to the top of the rotating body 20 is formed in the position range of the guide hole of the lid bottom body It is fixed by the fastening member is configured to rotate the rotating body 23 to open and close the lid by circular motion along the guide hole around the hinge axis (H) of the interruption.

The driving means 40, the clutch 50, and the lever A 60 are seated in a separate case C and fixed to the lid bottom body 30 by bolts.

Referring to the operation of the present invention configured as described above are as follows.

First, a case in which electricity is supplied will be described in which the lid is automatically opened and closed by the operation of a switch (not shown).

As shown in (a) of FIG. 3, the lid is closed so that the locking protrusion 11 of the inner cooker 10 and the locking protrusion 21 of the rotating body 20 are engaged with each other. As the driving means 40 is driven and electricity is supplied at this time, the disk 52 of the clutch 50 is in close contact with the main body 51.

In other words, the driving force is transmitted to the transmission gear 53 formed in the upper portion of the disk 52 to rotate in the direction of the arrow O.

This means that lever A 60, which is engaged with the transmission gear 53 and one side is linearly moved in the direction of arrow P, and lever B 70, which arcs around the hinge axis H, has a lid bottom 30. Along the guide hole 31 of the circular arc in the direction of the arrow Q to close the lid.

When opening the lid, as shown in (b) of FIG. 3, the transmission gear 53 is rotated in the direction of arrow R, and lever A 60 having one side engaged with the transmission gear 53 is straight in the arrow S direction. The motion of the lever B (70) is to move the circular arc in the direction of the arrow T along the guide hole 31 of the lid bottom 30 around the hinge axis (H) to open the lid.

Next, the case of manually opening and closing the lid when the supply of electricity is cut off will be described.

When the electricity is cut off, the driving source is lost, so that the electromagnet of the clutch 50 loses its magnetism, and the disk 52 is separated from the main body 51. Therefore, when the handle 22 formed on one side of the rotating body 20 is manually operated, the lever B 70 connected to the rotating body 20 is circularly moved in the direction of the arrow Q or T, which in turn is the lever A 60. To linearly move in the direction of arrow P or S to open and close the lid.

At this time, since the disk 52 of the clutch 50 is separated, the disk 52 on which the transmission gear 53 is formed rotates idle and blocks the transmission of force to the main body 51 such that the driving motor 41 or the driving gear is prevented. 42 is not overloaded, so even if the lid is opened or closed by manual operation, there is no effect on the gear.

As described above, the present invention constitutes a clutch that is in close contact with the main body by supplying / closing electricity, and performs the opening / closing operation of the lid in parallel with the automatic and manual, eliminating the inconvenience of being used in only one way. It is a useful design that increases the quality and reliability of the product.
