JPH0833Y2 - Basket holder for coffee makers - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention ensures that the basket is set properly so that the dripping prevention function provided at the liquid outlet at the bottom of the basket of the filtering section of the coffee maker operates normally. The present invention relates to a basket pressing device for a coffee maker.

[Conventional technology]

In a conventional coffee maker, as shown in FIG. 2, hot water W is poured into coffee powder to extract the coffee liquid through a paper filter in the basket 1 of the filtration unit, and a predetermined glass is discharged from the liquid outlet 2 at the bottom. A drip prevention valve 4 is provided at the liquid outlet 2 at the bottom of the basket 1 although it is dripted into the container 3.

That is, in this coffee maker, the drop prevention valve 4 opens only when the glass container 3 is set at a predetermined position, and the drop prevention valve 4 closes the liquid outlet 2 when the glass container 3 is removed. .

In this case, as shown in FIG. 3 which is an enlarged vertical sectional view of the main part of the arrow A in FIG. 2, the mill case 5 of the crushing unit for crushing coffee beans and the basket cover 6 of the basket 1 are shown.
With the main body lid 7 pressed in, the glass container 3
Generally, the structure is such that the dripping prevention valve 4 opens only when is set.

However, the main body lid 7 made of resin may have a holding boss portion formed inside the main body lid 7 for holding the basket 1 depending on the manufacturing error and warpage due to heat during use or the degree of deformation such as twisting. 8 is basket cover 6
, The basket cover 6 cannot be pressed, and the basket 1 rises accordingly, and the drop prevention valve 4 does not open sufficiently even if the glass container 3 is set, or the lever of the drop prevention valve 4 is tilted sufficiently. However, as a result, there is a problem in that the coffee liquid does not flow down from a predetermined position and flows backward.

Therefore, if the pressing boss portion 8 is formed to be long, the pressing of the basket cover 6 is surely performed, but if the pressing is strong due to variations in manufacturing or mounting, the reaction force that pushes up the main body lid 7 However, there is a problem that the coffee maker main body 10 and the main body lid 7 have a gap at the abutting portion, and the appearance is deteriorated.

[Problems to be solved by the device]

The present invention has been made to solve the above-mentioned conventional problems, and can absorb variations in the pressing stroke of the basket cover even when the lid of the main body or the like is slightly deformed, and a drop provided at the liquid outlet of the basket. It is an object of the present invention to provide a basket pressing device for a coffee maker in which the prevention function reliably operates.

[Means for solving the problem]

As a means for solving the above problems, a basket pressing device for a coffee maker according to the present invention is a device for pressing a basket cover of a main lid of a coffee maker, which has a dripping prevention function such as a dripping prevention valve at a liquid outlet provided at the bottom of the basket. The boss is formed by providing an elastic material whose lower end contacts the basket cover.

As the elastic material, any material such as soft silicone rubber, a coil spring, or a composite of soft rubber and spring may be used. The elastic material absorbs variations in the stroke of the pressing boss portion with respect to the basket cover.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view of a main part of a presser device of a coffee maker according to an embodiment of the present invention, and FIG. The present invention is applied to a coffee maker having substantially the same structure and function as the coffee maker of the conventional example shown in FIGS. 2 and 3 and having a drop preventing function. In this embodiment and the conventional example, The same parts are indicated by the same part numbers.

That is, in FIG. 1 showing the same portion as FIG. 3, the lower end is brought into contact with the pressing boss portion 8 of the basket cover 6 of the main body lid 7 attached to the upper portion of the coffee maker main body 10 so that the lower end of the basket maker 6 is flexible. An elastic material 12 made of a material capable of absorbing variations due to elasticity such as silicone rubber is provided, and thereby elastically holds the main body lid 7 against the basket cover 6 to absorb variations in the holding stroke. .

In this embodiment, the basket cover 6 also presses the mill lid 9 on the mill case 5.

[Effect of device]

As described above, according to the coffee maker provided with the basket pressing device of the present invention, even if there is a manufacturing error in the resin main body lid or some deformation during use, the pressing stroke for the basket cover is reduced. The unevenness can be absorbed by the elastic body, and as a result, the basket is always set while being reliably pressed by the main body lid, so the drop prevention function operates reliably and coffee liquid flows down normally from the liquid outlet of the basket. As a result, it is possible to completely prevent problems such as backflow and overflow of coffee liquid.
