Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drip-type coffee extractor having a main body and a detachable water container, and more particularly to a configuration for preventing a water container from falling over.

2. Description of the Related Art Generally, in a drip-type coffee extractor having a detachable water container, as shown in FIGS. 6 and 7, the water container 1 has a projection 2 having a through hole on the lower surface and a concave portion of a main body 3. 4 and attached. The water supplied from the water container 1 is supplied to a filter 6 containing coffee grounds heated by a heating element 5, and the extracted liquid is received by a bottle 7. The upper surface of the water container 1 is covered with a main body cover 8. Generally, the water container has a rectangular parallelepiped shape that is long in the vertical direction. Reference numeral 9 denotes a leaf spring that presses the upper edge of the water container 1.

Problems to be Solved by the Invention In such a conventional configuration, when water is stored in the water container, the center of gravity is high and unstable, so that due to an external impact,
There was a risk that the water container would fall off the main body and fall. For this purpose, it is necessary to harden the spring force for pressing the upper edge of the water container, or to firmly engage the water container with the main body. As a result, the operation of attaching and detaching the water container becomes difficult and the usability is extremely poor. there were.

Means for Solving the Problems In order to achieve the above object, a first means of the present invention comprises:
A main body having a step portion, a rising wall forming a recess in the step portion, and a substantially rectangular parallelepiped water container having a flange portion and a projecting piece formed on a lower surface so as to cover an outer periphery of the rising wall; A coffee extractor comprising a heating element for heating water flowing from the water container, a filter for injecting hot water supplied from the heating element to extract coffee liquid, and a glass container for receiving the coffee liquid, The water container is attached to the main body and stands upright, and the projection of the water container is supported by being inclined in contact with the upper edge of the inner wall of the rising wall and the lower end of the flange portion of the water container in contact with the outer periphery of the rising wall. That's what I did.

The second means is provided with a substantially triangular projection protruding from the outer periphery of the rising wall of the main body 1. And is supported in an inclined manner.

Operation In the above-described first means, even when an external impact is applied to the water container, the flange portion and the projecting piece of the water container are supported by the rising wall and held in an inclined state. According to the second means, since the flange portion is further supported by the projection provided on the rising wall, even if an external impact is further applied in an inclined state, the flange portion does not easily fall.

Examples Examples will be described below with reference to the drawings.

1 to 3 show a first embodiment of the present invention, in which 1 is a main body having a stepped portion 2 and a rising wall 3 is integrally formed on a side portion. A connection member 5 is provided inside the rising wall 3, and one end of the heating pipe 6 communicates with the connection member 5 integrally provided with the projection bar 20. Reference numeral 7 denotes a heating element made of aluminum die-cast, and the heating pipe 6 and the sheath heater 8
Are provided integrally. The other end of the heating pipe 6 is supplied with hot water to the filter 9 by a rising pipe (not shown). Reference numeral 10 denotes a glass container which is placed on the heating element 7 via a heat retaining plate 11 made of an aluminum plate or the like. Reference numeral 12 denotes this glass container lid. Reference numeral 13 denotes a water container, and a projection 14 having a through hole and a valve element 19 is provided on the lower surface. A groove is formed on the outer periphery of the projection 14, and an O-ring 15 is mounted. The width of the groove is larger than the width of the O-ring. The water container 13 is mounted by inserting the projection 14 into the connecting member 5.
A flange portion 16 and a third
The projection piece 17 shown in the figure is formed integrally. 18 is body 1
This is a leaf spring fixed to.

In the above configuration, when the water container 13 is mounted, the protrusion 14 provided on the lower surface of the water container 13 is inserted into the connecting member 5 from an oblique direction and rotated toward the main body. The upper edge of the water container 13 is supported by being urged by a leaf spring 18 in an upright state. When the water container 13 is mounted, the valve body 19 provided at the lower portion is pushed upward by the upwardly projecting projection bar 20 provided at the center of the connection member 5, and the valve body 19 is opened, and water in the water container 13 is opened. It is supplied into the heating pipe 6. The water supplied into the heating pipe 6 is heated by the sheath heater 8 to generate bubbles, which increase the pressure in the heating pipe 6 and are accommodated in the filter 9 by a rising pipe (not shown). Coffee powder. In this case, even if an external impact is accidentally applied to the water container 13 and the protrusion 14 of the water container 13 comes off the connection member 5,
The projecting piece 17 provided on the water container 13 is once supported by the inner peripheral upper end of the rising wall 3 and the lower end of the flange portion 16 of the water container 12 abutting against the outer peripheral root of the rising wall 3, thereby preventing falling. You.

4 to 5 show a second embodiment, wherein 1 'is a main body having a stepped portion 2', a rising wall 3 'on the side and a substantially triangular outer surface of the rising wall 3'. The projection 4 having a shape is integrally formed. Reference numeral 13 'denotes a water container. A flange 16' and a projection 17 'are integrally formed on the outer periphery of the lower surface of the water container 13'. Other structures are the same as in the first embodiment. In this case, even if an external impact is accidentally applied to the water container 13 ',
The protrusion 17 'provided on the water container 13' is formed on the inner peripheral upper end of the rising wall 3 'and the lower end of the flange portion 16' of the water container 13 'is formed on the rising wall 3'.
The water container 13 'is prevented from tipping over by contacting the inclined surface of the projection 4 so that even if an external impact is further applied outward in this state, the water container 13' will not tip over.

Advantageous Effects of the Invention As is clear from the above description, the present invention is safe because the water container is once inclined and supported even if an external impact is accidentally applied to the water container, so that the water container can be prevented from falling down. Further, it is not necessary to fix the engagement between the projecting portion of the water container and the main body in order to prevent the water container from overturning, so that the operation of attaching and detaching the water container becomes extremely easy. Further, as is clear from the second embodiment,
By providing the main body with the protruding portion, it is more firmly inclined and supported, so that even in this inclined state, it is possible to safely supply water, and there is an effect that usability is improved.
