Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a drip type coffee brewer.

Construction of conventional examples and their problems In general, drip-type coffee brewers heat water supplied from a water tank in a heating pipe, rise in the water rising pipe by the force of air bubbles and steam, and reach the coffee receiver. Coffee was obtained by dispensing and dripping from above the basket on which it was placed, and it had a structure with one water pipe.

With this structure, the hot water dripping onto the coffee grounds in the basket was not continuous, but was linked to the movement of steam in the heating pipe, and was inevitably discharged intermittently. With this intermittent discharge, the temperature of the hot water poured into the coffee grounds was lowered during the pauses, and the coffee grounds could not be sufficiently expanded. This can be seen from the fact that it takes about 9 minutes to heat around 4 cups (approximately 600 c.c.) of water with a heater of about 500 W and discharge it.

Purpose of the invention The present invention solves the above-mentioned conventional problems.
The purpose of this system is to provide continuous discharge and speedy extraction to shorten the time, and to work in conjunction with a timer to increase the steaming effect and extract flavorful coffee.

Structure of the Invention In order to achieve the above object, the present invention includes a plurality of heating pipes to which water is supplied from a water tank, and a timer controls energization of a heater that heats the heating pipes. be.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In the figure, 1 is an upper container consisting of a water tank 2 and an eaves part 3, 4 is a base on which the upper container 1 is placed and fixed, and between this base 4 and the eaves part 3 of the upper container 1 is , a coffee receiver 7 having a basket 5 for filtering coffee grounds and a basket lid 6 is housed.

Reference numeral 8 denotes a first heating element made of aluminum die-cast, which is housed in the base 4 and is in contact with the coffee receiver 7 with one side pressed against the heat insulating plate 9. A heating pipe 11 is provided. Reference numeral 12 denotes a second heating body formed by engaging an extension piece a with the side wall surface of the base 4 and screwing the other piece b; The heating body 8 and the heat insulating plate 9 are pressurized and held above the base 4. Reference numeral 14 designates a second sheathed heater that is held in place around the outer periphery of the second heating body 12 which also serves as a support plate, and 15 designates a second heating pipe that is similarly provided.

One end of the two heating pipes 11, 15 is connected to a check valve 15, 16 provided at the bottom of the water tank 2.
The other end is connected to the water tank 2 via the water tank 2, and the other end is connected to the discharge port 17 above the basket 5.
18 is a timer, and this timer 18 controls energization to the sheathed heaters 10 and 14. As shown in Fig. 5, the timer 18 is turned on and off for T ₁ hour at the initial stage of energization, and then turned off for T ₂ hours.
It's starting to turn on again.

In the above configuration, two discharge paths are provided, and two discharge paths are provided from the upper discharge port 17 of the basket 5.
Since hot water heated within the heating pipes 11 and 15 is jetted out, the intervals between them are canceled out, and a more continuous discharge state can be obtained. Furthermore, it can be seen that the intermittent time can be shortened by being able to complete the discharge in 4 to 5 minutes instead of half the conventional discharge time, for example, 9 minutes. Furthermore, this continuous discharge is effective in increasing the steaming effect of the next coffee powder.

The power supply to the sheathed heaters 10 and 14 is controlled by a timer 18, and after the coffee powder is evenly wetted with hot water during the initial power supply time _T1 , the coffee powder is swollen during the next OFF time _T2 . can be done. Furthermore, this
The OFF time _T2 may be about 20 to 60 seconds. Thereafter, the sheathed heaters 10 and 14 are energized again and coffee is extracted. At this time, since the two heating pipes 11 and 15 are provided, hot water is continuously discharged from the discharge port 17, so that the swollen coffee powder does not contract and the coffee components are extracted. A comfortable condition is maintained. Moreover, since the hot water is continuously dripped, the coffee extraction time is short, and the coffee liquid can be obtained while keeping unnecessary components suspended outside the bubbles due to the bubbles containing the gases released from the coffee.

Effects of the Invention As is clear from the above explanation, according to the present invention, when coffee extraction is controlled manually, the same effect can be automatically performed to obtain a flavorful coffee liquid. .
