Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a latch device for a cooking appliance, in particular, a latch device for a cooking appliance that combines a main body and a lid with a latch that is rotatably provided on the main body and a locking protrusion that is provided on the lid. The present invention relates to an improvement in a latch device that can be removably engaged by combination.

[Prior Art] In recent years, the number of types of cooking appliances used in general households has increased significantly, and they are extremely useful for improving cooking efficiency. There is.

A typical juicer consists of a cooking device main body that has a built-in electric motor for driving a juice separation basket, a juice separation container placed on the main body and used as a cooking container, and a lid body that is attached to and detached from the main body containing the separation container. It is equipped with

In this type of juicer, in order to securely hold the lid firmly against the main body with the juice separation container attached to the main body, conventionally, a latch and the lid body are rotatably provided on the main body. By locking with the engaging protrusion provided on the holder, the desired integral tightening and fixing can be obtained.

[Problems to be solved by the invention] However, in the conventional device, the latch and the locking protrusion have a structure that only provides a tightened connection state, and when the lid is tightened to the main body, internal e.g. There is a problem in that the close contact surfaces of the main body and the lid, or the lid and the youth separation container, stick together due to the juice liquid, and this sticking action makes it difficult to remove the lid. There was a problem in that when it was removed from the main body or the youth separation container, the liquid inside was spilled or the contact surface was damaged.

The present invention was devised in view of the above-mentioned conventional problems, and its purpose is to provide an improved latch device that can extremely easily separate the lid from the main body or from the juice separation container interposed therebetween. be.

[Means for Solving the Problems] In order to achieve the above object, the present invention is characterized in that the latch is provided with a push-up protrusion that pushes up the engagement protrusion on the lid body side.

[Function] Therefore, according to the present invention, when the latch is rotated to remove the lid from the main body, the push-up protrusion pushes up the engaging protrusion on the lid as the latch rotates, thereby pushing the engaging protrusion on the lid side upward. As a result, the lid and the main body or the juice separating container can be separated from each other with great ease, and cooking efficiency can be significantly improved.

[Embodiments] Preferred embodiments of the present invention will be described below based on the drawings.

FIG. 5 shows an embodiment in which the latch device of the present invention is used in a juicer, in which a juicer separation container 2 is included above the juicer main body 1, and a juicer separation basket 3 is sandwiched between the lid and the lid. Body 4 is attached.

In the embodiment, the youth separation container 2 faces the lid 4 as a member on the main body side, similar to the main body 1.

There are latches 5 on the main body side, that is, on both sides of the separation container 2.
is rotatably supported. A pair of locking protrusions 6 are provided on the lid 4 side at positions facing the latch 5. The latch 5 and the locking protrusion 6 engage with each other to removably connect the lid 4 and the main body 1 or the separation container 2. FIG. 1 shows the detailed structure of the latch 5 according to the present invention, and the latch 5 consists of a disc-shaped rotating part 5a and a handle 5b, and as shown in the side view of FIG. Reference numeral 5a is rotatably supported by a shaft pin 7 set in the main body, which is the separation container 2 in the embodiment.

The axis of the shaft pin 7 forms an eccentric shaft that is offset from the center of the rotating part 5a, and as a result, when the latch 5 is rotated, the rotating part 5a removably locks the locking protrusion 6. be able to.

As shown in FIG. 1, the rotating portion 5a is provided with a locking groove 5c, a part of which is connected to the latch portion 5.
closed by d.

1 and 2 show the open position of the latch 5. In this state, the locking groove 5c opens upward, and the locking protrusion 6 provided on the lid body 4 opens as shown by the arrow in the figure. It can easily penetrate into the locking groove 5c.

Therefore, if the handle 5b of the latch 5 is rotated counterclockwise as shown in FIG. 3 with the locking protrusion 6 inserted into the locking groove 5c from the state shown in FIGS. 1 and 2, the lid can be opened. The locking protrusion 6 of the body 4 is captured by the latch portion 5d inside the locking groove 5c, and the lid body 4 is separated from the main body by the tightening force determined by the shape of the latch portion 5d. It is tightened and fixed to the container side.

On the other hand, FIG. 4 shows a state in which the lid 4 is separated from the main body and the separation container 2, and the latch 5 is rotated clockwise as shown by the arrow. The locking protrusion 6
is released from the locking groove 5c of the latch 5, and the lid body 4 can be removed from the main body side.

A positioning protrusion 10 is integrally formed on the latch 5, and a stopper protrusion 11 is integrally formed on the main body side, in the embodiment, the separation container 2. As is clear from FIG. 4, in the standard open position of the latch 5, the rotational position of the latch 5 is determined with both protrusions 10 and 11 in contact with each other.

Therefore, the rotatable latch 5 has both protrusions 10 and 11.
The state in which the two protrusions 10 and 11 are in contact is defined as the reference open position, and by always attaching the lid 4 to the main body with both protrusions 10 and 11 in contact with each other, the user can always obtain the correct attachment position.

A feature of the present invention is that a push-up protrusion 8 is provided at one end of the inner surface 5e of the locking groove. This locking groove inner surface 5e is a part of a cylindrical surface whose central axis is the rotation axis of the latch. Therefore, while the locking protrusion 6 and the locking groove inner surface 5e are engaged, the lid body 4 is not pushed up. Then, when the latch 5 is further rotated, the locking protrusion 6 engages with the push-up protrusion 8. The push-up protrusion 8 is formed to protrude from the cylindrical surface of the inner surface 5e of the locking groove. Therefore, the push-up protrusion 8 pushes up the locking protrusion 6. In this way, the lid 4 that has been tightly fixed can be removed from the separation container 2 very easily.

Even if the lid 4 and the separation container 2 are in close contact with each other on the contact surface 2 with a sticky liquid such as juice, and the lid 4 is difficult to remove, the present invention allows for easy removal.

[Effects of the invention] As described above, according to the invention, the locking protrusion of the lid is pushed up by the push-up protrusion provided on the latch that rotates when the lid is separated from the main body. It has the advantage of being extremely easy to remove from the main body.
