Abstract
Description
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
Specifically, the outer periphery of the
By such a configuration, the
Therefore, when the
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
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
Meanwhile, in the case of the
In addition, in the case of the head lock
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.
According to a first embodiment of the present invention for achieving the above object, an inner pot having a plurality of flanges which are spaced apart at regular intervals from the outer periphery, the outer end; An inner pot lid for opening and closing with the outer pot lid and opening and closing the opening of the inner pot; The flange is formed to surround the inner portion of the inner pot and the flange of the inner pot, and provided with a plurality of engaging portions in a position corresponding to the flange of the inner pot, the flange while rotating along the flange portion of the inner pot and the inner pot lid A locking ring operable to operate the inner pot lid in a locked state or an unlocked state according to a relative position of the locking part; And an abrasion prevention plate installed between the flange of the inner pot and the locking portion of the locking ring to prevent abrasion occurring between the flange of the inner pot and the locking portion of the locking ring as the locking ring rotates.
According to a second embodiment of the present invention for achieving the above object, the inner pot having a flange extending outward from the outer peripheral top; An inner pot lid for opening and closing with the outer pot lid and opening and closing the opening of the inner pot; The inner pot cover and the inner portion of the inner pot lid is formed in a plurality of spaced apart from each other by a predetermined interval, so close to the edge portion of the inner pot lid or spaced from the edge portion of the inner pot lid is locked the inner pot lid Or a lock ring operable to be in an unlocked state; And an abrasion prevention plate installed between the flange of the inner pot and the contact surface of the locking ring to prevent abrasion occurring between the flange of the inner pot and the contact surface of the locking ring according to the operation of the locking ring.
Preferably, the wear protection plate is characterized in that it comprises a first plate provided on the inner surface of the lock ring in contact with the bottom surface of the flange or the bottom surface of the flange in contact with the inner surface of the lock ring.
Preferably, the wear preventing plate further comprises a second plate provided on the bottom surface of the flange or the inner surface of the locking ring in contact with the first plate.
Preferably, the wear protection plate is characterized in that the stainless steel or engineering plastics.
Preferably, the wear preventing plate is installed on the flange and the locking ring of the inner pot through screw fastening, rivet bonding or banding coupling.
The rice cooker having the wear protection device of the inner pot and the lock ring according to the present invention can prevent abrasion due to friction generated between the inner pot and the lock ring as the lock ring rotates or moves back and forth. Therefore, there is an effect that can prevent the phenomenon that the fine powder that may occur due to the wear into the inner pot.
Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of a cooker having a wear protection device of the inner pot and the lock ring according to the present invention.
