Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a beverage brewing device equipped with a beverage brewing machine that extracts raw material components by passing hot water through raw materials.

(B) Prior Art The beverage extraction machine of this type of beverage extraction device introduces hot water together with coffee or tea leaves into a mixing chamber whose floor is formed by a filter, applies pressure to the mixing chamber, and extracts the beverage through the filter. This is a common configuration. However, since the extractor generates a large amount of heat and requires a relatively long residence time to extract the raw material extract, there is a problem that the temperature of the beverage decreases. Therefore, Utility Model Application Publication No. 59-178787 and Utility Model Application No. 178787
Publication No. 60-25084 discloses a beverage brewing device configured to heat and supply liquid extracted by an extractor using a heat source of a hot water supply device.

(c) Problems to be solved by the invention However, according to the above-mentioned conventional technology, when a beverage supply device supplies the same beverage hot or cold, when supplying a cold beverage, the hot beverage from the beverage extraction device is must be cooled again, resulting in poor cooling efficiency. Moreover, in this case, a large amount of ice or cold water is used for cooling, which dilutes the beverage and reduces its taste.

The present invention therefore provides a beverage brewing device that can be effectively adapted to a beverage dispensing device capable of dispensing both hot and cold beverages.

(d) Means for solving the problem The present invention is equipped with a beverage extraction machine that extracts raw material components by passing hot water through the raw material, and a mixing bowl for mixing the extract from the beverage extraction machine with additives. In the beverage brewing device to be introduced into the beverage brewing machine, the outlet side of the beverage brewing machine and the inlet side of the mixing bowl are branched into two pipes, and a heater for heating is arranged in the middle of one pipe. This configuration includes a switching mechanism that opens only the heating-side pipe line when supplying a hot beverage, and opens only the other pipe line when supplying a cold beverage.

(E) Function When supplying hot beverages, the extract from the beverage extractor is prevented from decreasing in temperature by the heater and is guided to the mixing bowl while still hot. On the other hand, when dispensing cold beverages, the extract from the beverage brewing machine is guided to the mixing bowl without being hindered by the natural drop in temperature.

(F) Embodiment Figure 1 shows the system of a beverage supply device. When a solenoid valve 8 is opened by controlling the water level of a float 7 in a hot water tank 6, tap water is supplied from a water pipe 9 and the stored water is discharged. Hot water is heated by a heater 10 and supplied to a beverage brewing device 12 through a solenoid valve 11. Furthermore, when the solenoid valve 15 is opened by controlling the water level of the float 14, the cistern 13 is supplied with tap water from the water pipe 9 and stored therein, and when the pump 16 operates, the stored water is cooled in the water tank 18 by the cooling device 17. The mixing ball 2 passes through the cooling coil 19 arranged in the
1. The mixing bowl 21 is equipped with a stirring propeller 20 and mixes the coffee, sugar and cream supplied from the beverage extraction device 12, and passes through the chute 22 to the raw material tanks 23, 24.
Sugar and cream are introduced respectively. Hot or cold coffee mixed in the mixing bowl 21 is supplied to the cup 27 of the cup receiver 26 through the pouring nozzle 25. An ice maker 28 that makes ice using water supplied from the cistern 13 supplies ice to the cup 27 through a solenoid valve 29 when cold coffee is supplied.
The beverage raw material tank 30 stores coffee raw materials produced by grinding coffee beans in the coffee supply device, and sends a predetermined amount of coffee raw materials to the beverage extraction device 12 in response to a predetermined beverage supply signal. The beverage extraction device 12 includes a beverage extraction machine 1, and the outlet side of the extraction machine is branched into two pipes 2 and 3, and one pipe 3 is provided with a heater 4 for heating. The pipes 2 and 3 are connected to the mixing ball 2 by a three-way joint 31.
1, but only one side is opened by a switching mechanism 5.

The specific configuration of the beverage brewing device 12 will be explained with reference to FIG. 2. The beverage brewing device 1 has an opening 33 at the top into which coffee raw materials and hot water are introduced, and the raw materials and hot water are mixed in the mixing chamber 1A. Mix. During extraction, the mixing chamber 1A is in close contact with the beverage receiver 1B, and the beverage receiver 1
The filter 34 placed in the opening of B is on the floor. When the raw materials and hot water are mixed in the mixing chamber 1A, the beverage brewing machine 1 lowers the piston 35 by a drive device (not shown), compresses the internal air by the pressure of the piston 35, and pours the coffee through the filter 34 into the beverage receiving machine. Pull out to section 1B. After extracting coffee in this manner, the beverage brewing machine 1 raises the mixing chamber 1A together with the piston 35, separates it from the beverage receiving portion 1B, and replaces the filter 34. Three-way joint 36
Pipes 2 and 3 branched from the outlet side of the beverage extractor 1 are made of silicone tubes, and the switching mechanism 5 rotates cams 37 and 38 to switch levers 39 and 40.
The pipes 2 and 3 are opened and closed by crushing them.
In the standby state, the conduits 2 and 3 are not crushed and are open.

With the above configuration, when a cold beverage is supplied, the cam 38 is rotated 180 degrees and the lever 40 is pushed down to close the pipe line 3. Coffee is being extracted in the beverage brewing machine 1, and the extracted liquid flows through the pipe 2 and is introduced into the mixing bowl 21 through the communication pipe 32. The mixing bowl 21 mixes sugar and milk as needed, but when supplying cold beverages, cold water is sent out from the cooling coil 19 by the operation of the pump 16 and is supplied to the cup 27 together with ice from the ice maker 28. . In order to dilute the coffee with cold water when supplying cold beverages, the beverage extractor 1 extracts concentrated coffee using a small amount of hot water. Also, during the hot beverage supply operation, the cam 37
is rotated 180°, the lever 39 is pushed down, and the conduit 2 is closed, and the extract from the beverage brewing machine 1 is introduced into the conduit 3, and is introduced into the mixing bowl 21 while being reheated by the heater 4. And mixing ball 21
Mix with sugar and milk as needed and make 2 cups.
However, in the case of a hot beverage, since it is not diluted with cold water, the beverage extraction machine 1 performs extraction with one supply of hot water.

In this way, the switching mechanism 5 heats the extract with the heater 4 and introduces it into the mixing bowl 21 when supplying a hot beverage, and bypasses the heater 4 and directly transfers it to the mixing bowl 2 when supplying a cold beverage.
1. Therefore, when supplying a cold beverage, the cooling efficiency is good, and the dilution ratio between ice/cold water and the extract can be made small, and the taste of the cold beverage will not be diluted.

(g) Effects of the invention According to the invention, hot beverages do not need to be reheated after extraction, and cold beverages do not need to be diluted in large quantities, so the taste of the beverage does not deteriorate in either case. Therefore, a beverage brewing device is provided which is optimal for a beverage dispensing device for dispensing both hot and cold beverages. Furthermore, since only a small amount of ice is required when supplying cold beverages, there are also advantages such as the need for a small ice maker.
