Description

DETAILED DESCRIPTION OF THE INVENTION 1@Ming's Technical Field The present invention relates to a coffee extractor that extracts coffee liquid by supplying hot water from a hot water generator to coffee powder.

(@Ming's technical background) Conventionally x9, in order to extract a rich and delicious coffee liquid, - the entire coffee powder [first swell with hot water, that is, steam the coffee powder to make it easier to extract the extract of the whole coffee powder] It is known that it is good to re-supply hot water and extract the coffee liquid after brewing.The conventional two-way brewer with such a steaming function uses a hot water generator equipped with electricity and a timer. 9
Supply and stop of hot water by turning on and off the power [It is controlled so that when extraction starts, hot water is first temporarily supplied to the coffee grounds to steam the coffee grounds, and then hot water is continuously supplied to extract the coffee liquid. It is structured as follows.

[Problems with background technology]

However, in order to extract even more delicious coffee liquid, hot water is intermittently supplied to the coffee grounds not only at the beginning of extraction but throughout the entire extraction period, and the coffee grounds are steamed every time the hot water supply is stopped. It is better to extract the liquid, and considering this, conventional coffee extractors are still insufficient in terms of taste. Additionally, if intermittent hot water supply throughout the entire extraction period, such as in the upper rudder, is performed by turning on and off the hot water generator using a timer, there is a problem that the configuration becomes extremely complicated and expensive. .

[H aspect of invention]

Therefore, an object of the present invention is to provide, with a very simple configuration, hot water to coffee grounds intermittently throughout the entire brewing period, so that the coffee grounds can be steamed each time the hot water supply is stopped, and the coffee powder will have a rich and delicious flavor. Enjoy the pleasure of using a colored coffee brewer to extract coffee ″′-liquid.

[Summary of the invention]

The present invention is capable of storing hot water by providing a hot water storage tank that stores hot water that is continuously supplied from a hot water generating device, and also by providing a siphon mechanism that supplies the hot water in this hot water storage tank to the coffee brewing section using a siphon phenomenon. When the required amount of hot water is stored in the tank, that's it! ! The hot water is supplied to the coffee powder using a siphon mechanism, thereby making it possible to supply hot water intermittently throughout the entire period of coffee extraction.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to Figures 11g1 to 4. First, in Figure 181.

Reference numeral 1 denotes the body of a coffee brewer, which forms a water storage tank 2 on the left half of the drawing, and a cup mounting stand 3 below the right half.
and a relatively small capacity hot water storage tank 4r above.
t is formed. Reference numeral 5 denotes a hot water generating device, which is equipped with electricity and a heater (not shown) and is constructed by embedding a heating pipe 7 in a heating plate 6. The heating plate 6 is attached to the cup mounting table 3. The heat exchanger plate 3 is disposed in close contact with the lower surface of the heat exchanger plate 3. One end of the heating pipe 7 is connected to the water outlet 2& at the bottom of the water storage tank 2, and the other end extends upward to form a hot water supply pipe 8 and is connected to the hot water storage tank 4. Note that %9 is a check valve provided at the water outlet 2S of the water storage tank 2, and 10 is a lid removably provided on the top opening of the hot water storage tank 4. A hole 11 is formed in this lid 10. .

Reference numeral 12 denotes an inverted U-shaped pipe consisting of a siphon installed in the hot water storage tank 4, and one end of this inlet end 12m is connected to the hot water storage tank 4.
The inner bottom surface and the empty sky FJj1! The outlet end 12b, which faces the other end through the iIE part of the hot water storage tank 4, is fixed so as to penetrate watertightly and is located below the inlet end 12a. The inverted U-shaped pipe 12 supplies hot water in the hot water storage tank 4 to the coffee powder by a siphon effect as described later by determining the pipe diameter or the height difference between the inlet and outlet ends 12&, 12b, etc. At this time, the amount of hot water supplied per unit time is set to be greater than the amount of hot water supplied during the main time period 9, which is supplied from the hot water generating device 5 into the hot water storage tank 4.

On the other hand, a cup 14 is detachably placed on the heat transfer plate 3a. Reference numeral 15 denotes a filter which is formed into a cup shape and serves as a coffee extraction part, and a large number of liquid passage holes 16 are formed in the bottom part 15 of this filter. A flange portion 15b is formed at the bottom periphery. And, the above #115 is the flange part 15
The filter 17 is placed on the top opening of the cup 14 via the cap 14b, and a filter 17 is housed inside. A violet 18 is placed on the upper opening of the filter 15, and a relatively large circular hole 181 and a lifted ore scattering plate 19 are accommodated in the center of the violet.

Next, the operation of the above configuration will be explained. 2-Liquid [When brewing, the amount of water corresponding to the number of people is poured into the water storage tank 2, and the corresponding amount of coffee powder is also collected in the filter 15, and then the hot water generation device 5 energize the heater. Then, the water in the heating pipe 7 supplied from the water storage tank 2 is heated to generate hot water, and the hot water is pushed up inside the hot water supply pipe 8 by boiling pressure and flows into the hot water storage tank 4. Then, 9 liters of hot water flows into the storage tank 4.
! ! The hot water enters the inverted U-shaped pipe 12 while gradually increasing its water level as shown in FIG. Siphon phenomenon 9 The hot water in the hot water storage tank 4 flows out through the inverted U-shaped pipe 12 as shown by the arrow mark, and the hot water flowing out from the outlet end 12b of the inverted U-shaped pipe 12 flows through the lifting ore scattering plate 1.
By the way, as mentioned above, the amount of hot water supplied to the filter 15 by the inverted U-shaped pipe 12 is greater than the amount of hot water supplied to the hot water storage tank 5 by the inverted U-shaped pipe 12. int to 4.

Since the number of hot water storage links is set to increase
The water level inside the pipe gradually decreased, and as shown in Figure 4, the water level inside the inverted U-shaped pipe 12
When the temperature drops to the inlet end 12, air is sucked into the inverted U-shaped pipe 12 and hot water supply to the filter 15 is stopped. When this happens, the water level of the hot water in the hot water storage tank 4 rises again to cover the top of the 4U-shaped pipe 12. Since hot water is not supplied to the coffee grounds in the trench, the coffee grounds are The coffee powder is sufficiently steamed by the hot water supplied in the above manner, making it easy to extract the coffee extract, and when the hot water in the hot water storage tank 4 increases and hot water is supplied to the coffee powder again, the coffee powder becomes Since the coffee has been sufficiently steamed, a so-called rich coffee liquid is extracted, which is dripped into the cup 14 and stored. After that, the supply of hot water is stopped and supplied several times, and each time the supply is stopped, the two and one powders are steamed, the extract is extracted, and when the coffee becomes black, hot water is supplied and the coffee liquid is extracted. The series of steps is repeated until the desired amount of coffee liquid is stored in the cup 14.

In this way, according to this embodiment, hot water can be intermittently supplied to coffee grounds during the entire period of coffee extraction, so that the coffee grounds can be sufficiently steamed and the extract can be produced while hot water supply is stopped. west.

After that, the process of supplying hot water and extracting the coffee liquid is repeated several times, resulting in a richer and more delicious coffee liquid. Moreover, the hot water generating device 5
Intermittent hot water supply is performed using an extremely simple configuration in which boiling water is temporarily stored in a hot water storage tank 4, and each time the stored amount reaches a predetermined amount, it is supplied to a filter 15 by the siphon effect of an inverted U-shaped pipe 12. Since there are no moving parts, the structure is simple, and it can be manufactured at low cost. Furthermore, since a certain amount of hot water is stored in the hot water storage tank 4, and a siphon phenomenon occurs just in case, it is supplied to the T-filter 15 on the spot, the amount of hot water supplied per time is always approximately constant, and thus If the amount of hot water supplied per time varies greatly depending on the water temperature, as in the case where the electricity of the hot water generating device is switched off and hot water is supplied intermittently, this problem will not occur.

In addition, the siphon mechanism [- when constructed with a wooden tube.

It is not limited to an inverted U-shape like the one in the Jokiryo example, but as long as it exhibits a siphon phenomenon, the shape is in between.

FIG. 5 shows another embodiment of the present invention, and the differences from the previous embodiment will be described below. That is.

Reference numeral 20 denotes a pipe integrally protruding from the center of the bottom of the hot water storage tank 21, and an outlet end 20a, which is the lower end of this pipe 20, projects outward from the bottom of the hot water storage tank 21.

22 is located at the center of the lower surface of the lid 25 of the hot water storage tank 21 and
The upper part of the cylindrical body 22 is closed by an integral partition plate 22m. Therefore, pipe 2
0 and the cylindrical body 22 constitute a siphon mechanism 24, and when 92M is attached to the hot water storage tank 21, in the next state,
The cylindrical body 22 is inserted into the hot water storage tank 21 and the pipe 22
It is a foreshadowing covering the outside of the wall from above. Note that 25 is a hole formed in 1123. Even with this configuration, when the water level in the hot water storage tank 21 reaches the level of the partition plate 221, the hot water will flow out as shown by arrow B due to the siphon phenomenon.
The same effects as in the example can be obtained.

〔Effect of the invention〕

As is clear from the above description, the present invention has a hot water storage tank and a siphon mechanism for supplying hot water to the coffee brewing section by a siphon phenomenon whenever a predetermined amount of hot water is stored inside the tank. Hot water can be intermittently supplied to the coffee powder throughout the entire coffee extraction period, making it possible to extract a richer and more delicious coffee liquid.Moreover, such intermittent hot water supply can be performed using a siphon mechanism without using a timer or the like. Since the siphon phenomenon is utilized, it is possible to provide a coffee extractor with excellent effects such as simple structure and cost reduction.
