Description

[Detailed Description of the Invention] The present invention relates to a hot water pouring device used for supplying hot water to a drip-type coffee brewing device.

In general, the drip type is said to be the best way to make delicious coffee, but when pouring coffee powder into hot water using a drip type coffee brewing device, it takes a lot of time and effort to pour hot water using a regular water heater. It is extremely difficult to maintain the water temperature at 95°C to 96°C, which is the optimum temperature for pouring water. The object of the present invention is to provide a simple hot water pouring device that can pour hot water close to the boiling point in an arbitrary amount when pouring hot water into a drip-type coffee brewing device.

This idea was originally proposed by the applicant in 1983.
This invention relates to an improvement of the invention of No. 10413 (publication of Utility Model Publication No. 58-55865). The invention of the above-mentioned earlier application closes the gap between the bottle and the lid by pressing the lid floatingly provided on the bottle, increasing the vapor pressure inside the bottle, and increasing the steam pressure from the pipe penetrating the lid. It is designed to discharge hot water. It is desirable to make the bottle from glass so that it can be confirmed that there is water inside, but with glass it is difficult to make the rim of the bottle accurately flat, and even when the lid is pressed down, the lid and the rim of the bottle do not overlap. It has been difficult to completely close the gap between the two, and it has been difficult to mass-produce hot water pourers with uniform hot water flow. There is also a problem in that steam leaking from the gap between the lid and the rim of the bottle is sprayed onto the hand that is pressing down on the lid during pouring, giving the user a sense of danger of being burned. The present invention improves these problems.

An embodiment of the present invention will be described below in detail with reference to the drawings.
In Fig. 1, 1 is a water boiling bottle made of heat-resistant glass, and a supporting frame 2 has a heating device 3 placed on a base plate 2a.
It is placed on the trivet portion 2b. The bottle 1 has a wide mouth part 4, and a lid body 5 has a seal 5a on the wide mouth part 4.
It is fitted airtightly. 6 is a hot water supply pipe leading from the bottom of the bottle to the outside of the bottle, and the lid body 5
It penetrates through and is airtightly attached to the lid.
7 is a large opening on the surface of the lid body 5, and a valve seat 8a is provided on the upper edge of the tube in the upper short cylindrical edge 7a.
A valve seat opening 8 made of a heat-resistant elastic material such as silicone rubber is fitted. As shown in FIG. 3, a lever 9 has a U-shaped cross section that passes over the valve seat opening 8 in the diametrical direction, and one end is connected to a pin 10 provided on the bent portion 6a of the hot water pipe 6 on the lid body 5. It is supported by a fulcrum on the lid body 5. Reference numeral 11 denotes a hairpin-shaped spring that is wound around the pin 10 and interposed between the inner surface of the back of the lever 10 and the upper surface of the bent portion 6a.
It has the effect of flipping upward. Reference numeral 12 denotes a valve whose lower surface is formed into a partially spherical surface, and the valve shaft 13 has a neck portion 13a.
is thin and fitted into the lever 12 so as to be slidable in the axial direction, and 14 is a coil spring compressed and interposed between the back of the lever 9 and the valve 12 around the valve shaft 13. Reference numeral 15 designates a lever operating rod pivotally connected to the free end of the lever 9. As shown in Fig. 2, the lever operating rod 15 is made of a long wire bent into long, thin parallel pieces, and is designed to be able to hang downward, with a finger rest at the lower end. 15a. 17
18 is a scale line for checking the amount of hot water supplied, and 18 is a handle for the entire device.

To pour hot water using the above-described device, first remove the lever operating rod 15 from the locking portion 16 and lift it diagonally upward as shown by the dashed line. By lifting the lever 9, the valve 12 also moves away from the valve seat opening 8, so the lever operating rod 15 is returned to the tip side of the hot water supply pipe 6, and water is poured into the bottle 1 from the valve seat opening 8. Next, pinch the finger hook 15a and return the lever operating rod 15 to its original position, allowing it to hang downward. In this state, the lever 9 is slightly raised by the action of the spring 11, and there is a gap between the valve 12 and the valve seat 8a. When the combustion device 3 is ignited and the bottom of the bottle 1 is heated, the temperature of the water rises and begins to boil. In this case, steam is ejected from the gap between the valve 12 and the valve seat 8a. Now, when you put your finger on the finger hook 15a and push the operating rod 15 downward, the lever 9 will go down and the valve 12 will open.
is pressed against the valve seat 8a, the valve port is closed, and the water surface 19
The steam pressure above increases and the boiling water flows out from the hot water pipe 6. Therefore, place the coffee server 21 on the coffee cup 20 in advance, put the coffee powder 23 into the filter 22, and pour the hot water pipe 6 into the coffee powder.
By pouring more hot water, you can brew coffee at a temperature of 95-96°C, which is the perfect temperature for coffee extraction. In the above case, by reading the drop of the water surface 19 on the scale line 19, the amount of hot water to be supplied can be determined. When the hot water supply is completed in this way, when the finger pressing the finger hook 15a is released, the valve 12 floats above the valve seat 8a, the steam pressure on the water surface 19 decreases, and hot water stops flowing out from the hot water supply pipe 6.

The valve 12 is movable in the valve axis direction with respect to the lever 9, and the spring 14 is interposed between the valve 12 and the lever 9. Therefore, the valve 1 is moved by adjusting the force with which the finger hook 15a is pressed down.
The load that presses the valve seat 8a against the valve seat 8a can be adjusted to adjust the leakage of steam from between the valve and the valve seat, thereby adjusting the outflow rate of hot water. 16
is used to prevent the operating rod 15 from swinging.

When using a drip-type device to brew coffee, pouring hot water into the ground coffee using a regular water heater will
It is difficult to obtain hot water at 95℃ because the water cools down while you pick up the water heater and pour it into the water.However, this invention is based on the above, and allows you to pour hot water at 100℃ in a bottle with a lid. Because hot water is poured directly into the body through a hot water pipe, the time it takes to cool the hot water is extremely shortened, making it easy to obtain hot water of over 95 degrees Celsius.

The lid is airtightly fitted to the bottle mouth in advance.
Since this part is not a moving part, it is easy to achieve airtightness, and since the steam escapes from the valve seat opening, which has a smaller area than the lid, the force required to close the valve seat opening is small, and all you have to do is push down the lever 12 lightly. Pouring is possible. In addition, water can be supplied through the valve seat opening by lifting the valve, and there is no need to remove the lid each time, making the water supply operation easy.
