Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a coffee brewer having a removably attached coffee basket on the upper eave of the main body.

Conventional structure and problems Generally, in a drip-type coffee boiler, coffee grounds are poured into the basket, hot water is passed through it, and the coffee liquid is extracted.The coffee basket is placed in engagement with a glass container that receives the coffee liquid. The usual structure was to provide a space between the main body and the basket, place it on a heat insulating plate built into the main body, and brew coffee.

However, in recent years, in order to make handling of the glass container more convenient after brewing the coffee liquid, the basket is removably attached to the top of the main body by fitting the eaves of the main body with a part of the flange of the basket. Products that can be taken out independently are now available. In addition, a basket is hung on the eaves of the main body, and the extraction hole of the coffee basket is opened and closed using a valve, etc., and the coffee can be removed even in the middle of extracting the coffee liquid by removing the glass container. Coffee brewers have been provided that are configured to stop dripping.

As described above, in a coffee boiler having a removably attached basket above the main body and a valve mechanism, it is necessary to attach a separate rail-shaped part in order to fit the basket to the upper part of the main body. Ease of assembly was poor because separate parts were attached to the top of the main body. In addition, because the parts are separate parts, they are expensive.

Furthermore, it is customary to use thermoplastic resin for the main body and coffee basket due to its good moldability and low cost.In particular, since hot water is poured into the basket, the locking part is made of thermoplastic resin. The dimensions of the basket made up of the basket changed, and the force required to attach and detach the basket from the main body changed, making it unstable.

In addition, the basket was difficult to stay in place, and the brewing hole of the coffee basket could not be opened completely, resulting in coffee liquid overflowing from the coffee basket.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks and provides a coffee brewer that is easy to use.

Structure of the Invention The present invention provides a pair of rail parts on the lower surface of the eave part of the main body, from which the flange part of the coffee basket is suspended, and when the coffee basket is attached to the eave part, the locking piece of the coffee basket is engaged. By providing a matching lock spring on the eaves, the basket can be stably attached and detached.
