Description

Electric cooker

The present invention relates to an electric cooker, and more particularly, an electric appliance that improves the safety of the product by improving the visibility to easily grasp the locked and unlocked states of the inner pot containing food, but improving the appearance of the product. It is about the cooker.

In general, an electric cooker is a device used to cook food, and includes a main body in which an inner pot in which food is accommodated, and a lid covering an upper portion of the main body.

Here, the electric cooker can cook food therein by heating the inner pot in which the food is accommodated by a hot plate or an induction heating method, such as an electric rice cooker or an electric pressure cooker.

1 is an exploded perspective view showing a lid 1 of a conventional electric cooker.

As shown in FIG. 1, a conventional electric cooker is provided to lock and release the inner pot by rotating the locking handle 2 provided on the upper side of the lid 1. Here, the inner pot may be held in a locked state as the locking ring 3 rotated with the locking handle 2 is engaged with the upper edge of the inner pot. Further, by turning the locking handle 2, the locking ring 3 is released from the upper edge of the inner pot, and the lid 1 is opened to open the inner pot.

At this time, the user can check whether the inner pot is in a locked or unlocked state by checking the rotational direction of the lock handle 2 or the lock/release mark provided on the periphery of the lock handle 2.

However, when the conventional locking handle 2 is provided in a circle or regular polygon shape, it is difficult to grasp the rotation direction, so not only the external design is limited to a rectangular shape such as a bar capable of grasping the rotation direction, but also Even when provided in a bar shape, there is a problem in that the visibility is poor in a place where the distance from the electric cooker is far or dark.

Accordingly, it was difficult to easily grasp the locked state of the inner pot unless the user had a special awareness of safety, and if the safety device preventing heating in the unlocked state did not operate correctly, the lid 1 during cooking may cause pressure in the inner pot. There was a serious safety problem, such as not being able to withstand and ejecting the contents.

In addition, various safety devices or sensors are provided inside the lid 1, and the safety devices or sensors may be interconnected with a control unit provided inside the main body through a lead wire.

However, in the prior art, in the process of pulling the lead wire toward the main body during assembly, the lead wire is excessively pulled and the connection portion of the lead wire is disconnected. In addition, when the lock handle (2) is rotated or the lid (1) is opened and closed, the lead wire is flowed and the cover is peeled off due to abrasion and damage due to friction with the internal structure, or the operation of the lock handle (2) and the lid (1). There was a problem to restrain and interfere.

In addition, since the electric cooker is easily exposed to moisture due to water supplied together during cooking and steam generated during cooking, there is a concern that serious safety problems may occur in case of a disconnection or a short circuit.

Here, a rod wire passing through the terminal hole 133 may be inserted into the constraining groove 132.

In this case, the locking portion is preferably provided with a mounting protrusion (132a) protruding from the edge of the constraining groove 132 and disposed to face each other.

Here, the seating protrusions 132a may have ends facing each other so as to be inclined upward, and an upper surface connected to the end may be flatly provided so that the guided lead wire is seated.

In addition, as the terminal b of the lead wire w is coupled to one side of the control unit, the lock display lamp unit 30 is electrically connected to the control unit.

In detail, when the locking display lamp unit 30 and the lamp receiving unit 131 are coupled, the terminal b of the lead wire w is passed through the terminal hole 133 of the lamp receiving unit 131, The locking display lamp unit may be inserted into the lamp receiving unit 131 by pulling the passed lead wire w.

Here, the lead wire w that has passed through the terminal hole 133 is pulled upward, and may be inserted into the constraining groove 132 through the mounting protrusion 132a disposed oppositely. At this time, it is preferable that the distance between the opposite ends of the respective seating protrusions 132a is equal to or smaller than the width of one side of the lead wire w.

That is, the lead wire (w) is guided by being slid upward along the end inclined surface of the seating protrusion (132a) and inserted into the constraining groove (132), and the inserted lead wire (w) is It is seated on the upper surface and can be restrained without deviating from the bottom.

In this way, the lead wire w is simply inserted into the constraining groove 132 without a fixing means such as a separate adhesive, and thus the productivity of the product can be improved by simplifying the assembly process.

In addition, the lead wire (w) seated on the upper surface of the seating protrusion (132a) is disposed spaced apart from the inner lid, so that it does not directly rub against the inner lid (11) when the rotary handle rotates, so the lead wire (w By preventing damage to the coating of ), the safety and durability of the product can be improved.

As described above, the present invention is not limited to each of the above-described embodiments, and it is possible to be modified and implemented by those of ordinary skill in the art without departing from the scope claimed in the claims of the present invention. And, these modifications are within the scope of the present invention.
