Abstract

PURPOSE:To provide a coffee maker for which water can be supplied in the water tank by a simple operation. CONSTITUTION:The title coffee maker has a constitution by which water in a decanter 7 can be automatically supplied in a water tank 3 by placing the decanter 7 on the loading surface of a main body 1 and communicating with a first communicating valve 8 of the previously mentioned decanter 7 with a second communicating valve 4 of the water tank 3.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called drip type coffee boiler.

0002

[Prior Art] As a conventional example, for example,
As disclosed in Publication No. 556, water for the desired number of people can be poured into a decanter and then poured back into the water tank, or
Alternatively, you had to take the trouble of removing the water tank from the main unit, pouring water directly into it, and then putting the water tank back into the main unit.

0003

SUMMARY OF THE INVENTION The present invention was devised in consideration of the above points, and an object of the present invention is to provide a coffee boiler that is extremely easy to use.

0004

[Means for Solving the Problems] The present invention provides a water tank heated by a heater inside the main body, and a mounting surface is formed on the upper surface, and the water tank is connected to the outside via a check valve. A decanter with an upper opening is attached to and removed from the mounting surface, and a chamber facing the opening of the pipe is attached to and removed from the upper opening of the decanter. The bottom part and the top part of the water tank are connected by a normally closed first communication valve and a normally closed second communication valve, and the decanter is placed on the mounting surface and the first communication valve and the second communication valve are connected. When the two communication valves are connected, both valves are opened to communicate the decanter and the water tank, and the two valves are closed after a predetermined time or a predetermined temperature has elapsed.

[0005]

[Operation] In other words, by simply putting the desired amount of water into the decanter, placing it on the mounting surface of the main body, and connecting the first and second communication valves, the water in the decanter will automatically drain. This is supplied to the water tank inside the main unit.

[0006]

Embodiments Examples of the present invention will be explained based on the drawings.

Reference numeral 1 denotes a coffee boiler body, which is provided with a water tank 3 heated by an electric heater 2 inside. This water tank 3 is provided with a second communication valve 4 that communicates with the outside of the main body 1. Further, a pipe 6 is connected to the bottom of the water tank 3 via a check valve (not shown). The pipe 6 is erected outside the main body 1.

Reference numeral 7 denotes a decanter that is attached to and removed from a mounting surface formed on the upper surface of the main body 1, and is provided with a first communication valve 8 connected to the second communication valve 4 and a skirt 9 on the outer periphery of the bottom. It protects the first communication valve 8 of the lever.

Reference numeral 10 denotes a chamber provided at the top opening of the decanter 7, which is provided with a paper filter 11 for storing coffee powder therein, and which faces the opening of the pipe 6. I have to.

The first communication valve 8 is composed of a lid portion 50, a first on-off valve 13 that is constantly pressed by a first spring 30, and a packing 51. The flange portion 15 formed on the first on-off valve 13 separates from the inner bottom of the decanter 7 when the protruding portion 52 is pushed up from below, forming a first passage 16. 1 spring 30
The first passage 16 is closed by being pressed against the inner bottom of the decanter 7.

The second communication valve 4 includes a cylindrical portion 55, a second on-off valve 21 which is H-shaped and is pushed down by the biasing force of the second spring 23 and which forms the second passage 24, and which is normally curved upward. A shape-variable member 20 that changes from an upward curve to a substantially horizontal straight state after a predetermined temperature or a predetermined time has elapsed, and a base 60
It is made up of.

The second on-off valve 21 is constantly pushed down by the biasing force of the second spring 23, and as shown in FIG.
4 is closed by the cylindrical portion 55.

[0013] To explain the effects of this configuration, first,
The first on-off valve 13 of the first communication valve 8 is connected to the
With the passage 16 closed, water is supplied into the decanter 7, and then the decanter 7 is placed on the mounting surface of the main body 1 as shown in FIG. At this time, the variable shape member 20 curves upward as shown in FIG.
The passage 24 is closed by the cylindrical part 55, but when the decanter 7 is placed on the mounting surface of the main body 1 as described above, the cylindrical part 55 is pushed downward by the packing 51 and the second passage 24 is closed.
4 is opened and the first on-off valve 13 is switched to the second on-off valve 2.
The first passage 16 is pushed up by the upper part of the second passage 24
It is opened to communicate with.

Therefore, the water in the decanter 7 is supplied into the water tank 3 through the first passage 16 and the second passage 24.

When the shape variable member 20 is lowered to a predetermined temperature by the supplied water, it becomes horizontal as shown in FIG. It is pushed downward by force and closes the first passage 16 and the second passage 24.

Thereafter, hot water is produced by a well-known drip method and is supplied to the coffee grounds in the chamber 10 through the pipe 6.

[0017]

[Effects of the Invention] Since the present invention has the above-mentioned configuration, there is no need to take the trouble to supply water into the water tank as in the conventional case. It has the effect of automatically supplying water into the water tank just by placing it there.
