Abstract

PURPOSE:To enable a device to be certainly fitted on and to eliminate the possibility of falling down by setting an engaging section to be engaged with a projected section or a recessed section formed on a main body, at the upper edge section of a water vessel, and by engaging the projected section or the recessed section of the main body with the engaging section of the water vessel, even if external collision is applied to the water vessel. CONSTITUTION:In order to fit a water vessel 13 on a main body 1, a projected section 14 set on the lower surface of the water vessel 13 is inserted into a jointing member 5 in the oblique direction, and the water vessel 13 is rotated on the side of the main body 1 and is inserted at the same time. Under rotation, an engaging piece 17 is brought into contact with the projected section 25 of the main body 1 but is pushed down, and so it can be rotated further as it is. When a device is mounted, then by the force of a coil spring 21, the engaging piece 17 is reset to the original position. By resetting the engaging piece 17, the water vessel 13 is removed from the main body 1 due to oscillation or the like, and the possibility of falling down is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a drip-type coffee brewer having a main body and a removable water container.

2. Description of the Related Art In general, in a drip type coffee brewer equipped with a removable water container, as shown in FIGS. It is attached to the recess 400 of. Water supplied from this water container 100 is heated by a heating element 500 and supplied to a filter 600 that accommodates coffee powder, and the filtered extract is received in a bottle 7.

Note that the top surface of the water container 100 is covered with a main body lid 800. Further, generally, a water container has a rectangular parallelepiped shape that is elongated in the vertical direction. 900 is a leaf spring for pressing down the upper edge of the water container 100.

Problems to be Solved by the Invention In such a conventional configuration, when water is stored in the water container 100, the center of gravity is high and unstable. There was a risk that the water container 100 would come off the main body 300 and fall due to external impact. For this purpose, the force of the spring 900 that presses down the upper edge of the water container 100 may be increased, or the force between the water container 100 and the main body 300 may be increased.
It was necessary to stiffen the engagement at the bottom of the. As a result, it became difficult to attach and detach the water container 100, resulting in a problem that it was extremely inconvenient to use.

Means for Solving the Problems The present invention includes a water container attached to a main body, a heating element that heats water flowing from the water container, and hot water supplied by the heating element to extract coffee liquid. In the coffee extractor, the coffee extractor is equipped with a filter for filtering water and a glass container for receiving the coffee liquid. It is a coffee brewer.

Function: In the present invention, the water container is firmly held by the main body at its upper and lower ends, so that it will not come off even when subjected to vibrations or external shocks.

Example Embodiments of the present invention will be described below with reference to the drawings.

Figures 1 to 3 show the first embodiment. is a main body that is provided with a recess 4 for storing a water container 13, and has a step 2 below the recess 4; It is formed. A connecting member 5 integrally provided with a protruding rod 23 is provided inside the rising wall 3.
is provided, and one end of the heating vibro communicates with the internal space of the connecting member 5. Reference numeral 7 denotes a heating element made of aluminum die-casting, and the above-mentioned heat vibro and sheathed heater 8 are integrally provided. The other end of the heating vibro is connected to the filter 9 through a water raising vibrator (not shown) so that hot water can be supplied thereto. Reference numeral 10 denotes a glass container, which is placed on the heat generating element 7 via a heat insulating plate 11 made of an aluminum plate or the like. 12 is a lid of this glass container 10.

The water container 13 is provided with a convex portion 14 having a through hole 24 and a valve body 22 on the lower surface. A groove is formed on the outer periphery of this convex portion 14, and an O-ring 15 is attached thereto. Note that the width of the groove is larger than the width of the O-ring 15. The water container 13 is attached by inserting the convex portion 14 into the connecting member 5. On the other hand, a through hole 16 is provided on the upper edge of the outer surface of the water container 13.
A locking piece 17, which is an example of a locking part and has an uneven upper part, is inserted into the through hole 16 with play. 3
The illustrated cover 18 is fixed to the water container 13 by force-fitting its claws 19 onto the outer surface of the water container 13. 20 is a bottle integrally provided on the inner bottom wall of the cover 18.

Further, the coil spring 21 is connected to the bottle 20 as shown in the figure.
and the earthen wall of the locking piece 17. As a result, the locking piece is always urged upward.

Next, the operation of the embodiment of the present invention will be explained.

In the above configuration, in order to attach the water container 13 to the main body 1, the convex portion 14 provided on the bottom surface of the water container 13 must be connected to the connecting member 5.
, and insert the water container 13 into the main body 1 while rotating it toward the main body 1 side. During rotation, the locking piece 17 hits the convex portion 25 of the main body 1, but since it is pushed down, the locking piece 17 can be rotated further. Then, when the attachment is completed, the locking piece 17 returns to its original position by the force of the coil spring 21. By the return of this locking piece 17, the water container 1
3, there is no need to worry about it falling over when pulled out from the main body 1 due to vibration or the like.

When the water container 13 is attached, the valve body 22 provided at the bottom of the water container 13 is pushed upward by the upwardly convex protruding rod 23 provided at the center of the connecting member 5, and the valve body 22 is spaced. Water in the water container 13 is supplied into the heating vibro.

The water supplied into the heating vibro is heated by the sheathed heater 8 to generate bubbles, which increase the pressure within the heating vibro, and the water is poured onto the coffee grounds in the filter 9 by the water rising vibro. . In this way, coffee is extracted.

As explained above, since the water container 13 is supported by the main body l at its upper and lower ends, it will not come off even if an external impact is applied.

Next, a second embodiment of the present invention will be described. FIG. 4 is a partial plan view thereof, and FIG. 5 is a front view of the upper exterior location of the water container.

The structure other than the locking structure at the upper end of the water container 13 is the same as the first embodiment.

As shown in FIG. 5, a substantially rectangular through hole 16 having a convex portion 24 on the lower side is provided on the upper outer surface of the water container 13. As shown in FIG. The aforementioned locking piece 17 is fitted into the through hole 16 with some play.

At the same time, a coil spring 21 is installed between the convex portion 24 and the upper wall of the locking piece 17. Therefore, the locking piece 17 is
It is always urged upward by the coil spring 212. Note that the outer wall of the engagement +h piece 17 covers the coil spring 21.

As mentioned above, in this embodiment, the coil spring 21 is inserted into the through hole 1.
6, the amount of protrusion of the locking piece 17 from the outer surface of the water container 13 is small.

In addition, instead of the protrusion provided on the main body side, four parts may be provided and the protrusion may be configured to be engaged with the engagement part of the water container.

Effects of the Invention As is clear from the above description, in the present invention, even if an external impact is applied to the water container, the water container can be reliably attached by engaging the protrusion or recess of the main body with the locking portion of the water container. It has the advantage that there is no risk of it falling over.
