Abstract

PURPOSE: A rice cooker having a device for preventing an inner pot and a locking ring from being worn is provided to prevent fine powder from putting into the inner pot by preventing the wear due to the friction between the inner pot ant eh locking ring as the locking ring rotates or moves forth and back. CONSTITUTION: A rice cooker having a device for preventing an inner pot and a locking ring from being worn comprises an inner pot(120), an inner pot lid(130), a locking ring(110), and a wear preventing plate(140). The inner pot comprises a plurality of flanges(121) at constant intervals. The inner pot lid opens and closes the opening of the inner pot. The locking ring covers the flanges of the inner pot and the rim of the inner pot lid. The locking ring comprises a plurality of locking portions(114) corresponding to the flanges of the inner pot. While rotating along the flanges of the inner pot and the rim of the inner pot lid, the locking ring locks or unlocks depending on the relative location of the flanges to the locking portions. The wear preventing plate prevents the wear occurring between the flanges of the inner pot and the locking portions of the locking ring due to the rotation of the locking ring.

Description

Rice cooker having apparatus for preventing wear of inner pot and locking ring}

The present invention relates to a rice cooker having a device for preventing abrasion occurring between the inner pot and the lock ring, and more particularly, by preventing wear of the inner pot or the lock ring according to the locking and unlocking operation of the lock ring. It relates to a rice cooker having a wear prevention device of the inner pot and the lock ring to prevent the fine powder from abrasion into the inner pot.

In general, the electric rice cooker is provided with a lock ring (or opening and closing ring) to maintain the locked state and the unlocked state of the inner pot and the inner pot lid for opening and closing the inner pot food is placed. If the lock ring is in the locked position, the cooker lid does not open even if the user attempts to open the lid from the outside of the cooker, and the cooker lid can be opened only when the lock ring is in the unlocked position.

The structure of the locking ring between the inner pot and the inner pot lid of the rice cooker is shown in Figures 1 and 2.

1 is a view showing a rotary locking ring structure of the electric rice cooker, the rotary locking ring 110 shown in Figure 1 is installed to surround the outer periphery of the outer periphery of the inner pot 120 and the inner pot lid 130 , The inner pot lid 130 and the inner pot 120 operates to be locked or unlocked. Here, the inner pot lid 130 is installed to be opened and closed integrally with the outer pot lid (not shown) is opened and closed together when opening and closing the outer pot lid.

Specifically, the outer periphery of the inner pot 120 is formed with a flange 121 extending protruding a predetermined length to the outside, the flange 121 is spaced apart from each other by a predetermined interval along the upper outer periphery of the inner pot 120 Consists of dogs. In addition, the locking ring 110 is provided with a plurality of cutouts 111 to correspond to the plurality of flanges 121 formed on the outer circumferential upper end of the inner pot 120, that is, immediately below the cutouts 111 At the bottom of the ring 110 is spaced apart from each other by a predetermined locking portion 114 protruding in the direction of the inner pot, the locking ring 110 is the outer periphery of the inner circumference of the inner pot 120 and the outer circumference of the inner pot lid 130 And a lever 112 to rotate accordingly.

By such a configuration, the lever 112 is rotated along the circumferential direction of the inner pot 120 so that the engaging portion 114 of the locking ring 110 and the protruding flange 121 of the inner pot 120 engage with each other. If the inner pot lid 130 is in a locked state, and the locking portion 110 of the locking ring 110 and the protruding flange 121 of the inner pot 120 are in a position where the inner pot lid 130 is unlocked. Will be placed in.

Therefore, when the locking ring 120 is located in the locked state, the inner pot lid 130 is not opened even when the outer pot lid is opened.

2 is a view showing a head lock type locking ring structure of the rice cooker, in the head lock type locking ring structure, the locking ring 110 ′ shows a portion of the outer circumference of the inner pot 120 and a portion of the outer circumference of the inner pot lid 130. Installed to wrap, the inner pot lid 130 and the inner pot 120 operates to be in a locked or unlocked state.

Specifically, the locking ring 110 'is composed of four locking rings 110' spaced apart from each other at the upper end of the inner circumference of the inner pot 120, each locking ring (110 ') lever 112' Is provided, the lever (112 ') is moved to the outside of the inner pot 120 is in the unlocked state to open the outer pot lid can open the inner pot lid 130. On the contrary, when the lever 112 'moves to the inner pot 120 and is in close contact with the inner pot lid 130, the inner pot lid 130 is not opened even when the outer pot lid is opened.

Meanwhile, in the case of the rotary locking ring 110 shown in FIG. 1, when the locking ring 110 is rotated for the locking and unlocking state, the upper surface of the locking part 110 of the locking ring 110 and the inner pot flange ( Since the lock ring 110 rotates while the bottom of the 121 is rubbed, wear of the lock ring 110 or the inner pot 120 may occur due to frequent friction between the lock ring 110 and the inner pot flange 121. . When such a wear phenomenon occurs, fine powder is generated from the flange 121 or the locking ring 110 of the inner pot 120, and the fine powder may flow into the inner pot 120 to cause hygiene problems.

In addition, in the case of the head lock type locking ring 110 ′ shown in FIG. Abrasion may occur due to friction, and fine powder generated by the wear phenomenon may flow into the inner pot 120 to cause hygiene problems.

The present invention has been invented to solve the above problems, the inner pot and the locking ring of the inner pot or the lock ring which can prevent the fine powder from flowing into the inner pot by preventing the wear phenomenon of the inner pot or the lock ring according to the locking and unlocking operation of the locking ring It is an object of the present invention to provide a rice cooker having a wear protection device.
