Description

[Detailed Description of the Invention] The present invention relates to a coffee boiler that can also be used for brewing black tea with one basket.

Conventionally, when brewing tea with a coffee boiler, a basket for tea was prepared in addition to a basket for coffee. That is, when brewing black tea, it is necessary to soak the tea leaves in boiling water for a certain period of time to fully develop the taste, aroma, and color. However,
In coffee baskets, the residence time of hot water is short, and black tea components cannot be extracted sufficiently. Therefore, prepare a separate basket with a small extract outlet.
I tried to lengthen the residence time of hot water in the basket as much as possible. However, the amount of hot water poured into the basket per hour varies significantly depending on the heater capacity and water temperature in the water tank, and is not constant.
If the extraction liquid outlet of the basket is made too small, there is a problem that hot water will overflow from the upper edge of the basket.Therefore, since the outlet diameter is determined taking these points into consideration, the extraction of the components of black tea is insufficient. It was hot.

The present invention eliminates the drawbacks of the conventional example described above, and makes it possible to extract the components of both coffee and tea well with the same basket, and prevents hot water from overflowing from the basket even when the hot water supply speed is high. To provide a coffee boiler that is extremely easy to use. Hereinafter, embodiments will be described in detail with reference to the drawings.

The figure shows an embodiment of the present invention. In the figure, 1 is a water tank placed on a base 2, and a heating unit 4 is connected to the bottom of the water tank 1 via a check valve 3. An inlet 5 is connected to the inlet 5. The heating section 4 includes a sheathed heater 6 and a heating pipe 7 for guiding water from the introduction section 5, and the other end of the heating pipe 7 is connected to a rising pipe 8 having a discharge port 8a at the top of the vessel. It gets through. Reference numeral 9 denotes a ceiling-hanging basket whose peripheral edge is attached to the container body and can be attached and detached from the horizontal direction.It has a roughly V-shaped cross section, and has a liquid outlet 9a at the bottom and an overflow outlet at a part near the upper edge. It has a hole 9b and an overflow tube 9c for guiding the overflow liquid downward. 9
b is a handle by which the basket 9 can be operated. 9e
The extending rib protrudes downward to enclose the outflow port 9a with the overflow tube 9c, and one end is connected to the hole 9f provided in the wall of the extended rib 9e and the outer peripheral engagement portion 9g of the overflow tube 9c. An opening/closing lever 10 whose supporting end is slidable in the vertical direction is incorporated, and a water stop valve 11 disposed at the outlet 9a of the basket 9 is operated to open and close the outlet 9a. . Reference numeral 12 denotes a cup for receiving the coffee liquid, which is placed on a heat insulating plate 13 which is located below the basket 9 and is supported under pressure by the heating section 4 in the base 2. The cup 12 has a handle 12a for carrying, and a spout 12 on the opposite side.
There is b. A cup lid 14 is held and fixed on top of the cup 12 by engaging a portion 14a thereof to the handle 12a, and a hole 14 provided in the cup lid 14
b is a rotatable sliding plate 1 engaged with a claw 15a.
5 is included. Reference numeral 15b denotes a knob for operating the sliding plate 15, which has an opening 15c inside the sliding plate 15 and directly below the outlet 9a of the basket, and the sliding plate 15 rotates around this opening 15c. . The outer peripheral portion of the sliding plate 15 is provided with a partial stepped portion 15d that contacts the downwardly protruding portion 10a of the opening/closing lever 10 incorporated in the upper basket 9 and pushes the lever 10 upward. The cup lid 14 is partially cut out near the spout 12b of the cup 12 so that coffee liquid can be poured into other coffee cups with the cup lid 14 attached. The outlet 9h of the overflow tube 9c, which leads the overflow liquid, is positioned directly above the spout 12b of the cup 12. That is, basket 9 and cup 1
2 is set in the container as shown in the figure, and a cup 12 is placed below the outlet 9h of the overflow tube 9c.
The spout 12b of the basket 9 is located therein, and the opening hole 15c is located below the liquid outlet 9a of the basket 9. 16 is a thermostat attached to the heating section 4.

Next, the method of use and operation of this embodiment will be explained. First, when making coffee, pour the required amount of coffee powder ground to a suitable coarseness through a paper filter.
7 into the basket 9, and set the container by engaging the peripheral edge with the handle 9d. A predetermined amount of water is poured into the water tank 1, and the cup 12 is placed on the heat insulating plate 13. At this time, the knob 15b of the sliding plate 15 is operated to push the opening/closing lever 10 upward to open the outlet 9a. Next, when the heater is turned on, the sheathed heater 6 generates heat and heats the water in the heating pipe 7. Therefore, the water boils within the heating pipe 7, and the boiling water, ie, hot water, rises through the rising pipe 8 and drips into the basket 9 from the discharge port 8a. Then, while the hot water passes through the coffee powder, coffee components are extracted, and this coffee liquid drips into the cup 12 through the outlet 9a and the opening 15c and accumulates therein. Note that when the sheathed heater 6 generates heat, the cup 1 is
The bottom surface of 2 is also heated.

Further, when the water is heated and boiled in the heating pipe 7, the boiling water tends to flow back toward the water tank 1, but this is prevented by the check valve 3 closing. In addition, the water supply into the heating pipe 7 is as follows.
As the hot water in the heating pipe 7 is sent out to the water rising pipe 8 side due to boiling pressure, the inside of the heating pipe 7 becomes negative pressure, so the check valve 3 is opened and the water in the water tank 1 flows into the heating pipe 7. will be supplied to. Thereafter, in the same manner, all the water in the water tank 1 is continuously supplied into the basket 9 via the water rising pipe 8, extracts the coffee components, is filtered through the paper filter 17, and then flows into the cup 12 from the outlet 9a. It drips and accumulates. Further, as long as the cup 12 is placed on the heat insulating plate 13, the extracted coffee liquid receives heat from the heating section 4 and is kept at an appropriate temperature by the thermostat 16.

Next, we will explain how to make tea. First, a predetermined amount of water is poured into the water tank 1, and the required amount of black tea is poured into the basket 9 through the paper filter 17.
and place the cup 12 on the heat insulating plate 13. In this case, the outlet 9a of the basket 9 is
Operate the sliding plate 15 with the knob 15b to remove the protruding step part 1.
5d is separated from the protrusion 10a of the opening/closing lever 10 to keep it in the closed state. If hot water is supplied into the basket 9 in this state, the hot water will not flow out from the outlet 9a but will remain in the basket 9. Therefore, the tea leaves are fully immersed in the hot water, allowing the components, aroma, and color to be extracted. Then, when more hot water is supplied and the water level reaches the overflow hole 9b, the black tea extract overflows from the hole 9b, but the overflow liquid is transferred to the overflow tube 9.
c, and flows from the outlet 9h into the cup 12 via the spout 12b. Therefore, even if the supply speed of hot water from the discharge port 8a is fast depending on the specified heater capacity and water temperature, the problem of hot water overflowing from the basket 9 is eliminated, and the user can use the device with peace of mind even if he or she leaves the device. It is.

After sufficiently extracting the black tea components in this way, operate the knob 15b of the sliding plate 15 and push up the protruding end 10a of the opening/closing lever 10 with the protruding step 15d to open the outlet 9a of the basket 9. The tea liquid accumulated in the basket 9 passes through the outlet 9a and the opening hole 15c, and all accumulates in the cup 12. Thus, the black tea liquid, which has sufficiently extracted its color, aroma, and ingredients, is in the cup 12, and the thermostat 16
The temperature is maintained at an appropriate temperature.

As described above, according to the present invention, coffee and tea can be sufficiently extracted using the same basket 9.

Next, keeping coffee or tea warm inside the cup 12 will be described. The liquid in the cup 12 receives heat from the heating section 4 from the bottom surface of the cup 12 via the heat insulating plate 13. The heat retention temperature is determined by the balance between the amount of heating heat and the amount of heat dissipated, and the smaller the hole in the upper lid 14 of the cup 12, the better. In the present invention, the dripping part of the overflow liquid is the spout 12b of the cup 12.
The amount of heat dissipated is minimized without increasing the number of holes or the area of the lid 14 more than necessary. Therefore, the heat consumed for keeping warm can be reduced, and the supply of heat to the heating pipe 7 can be increased accordingly, and the configuration can be simplified.

Next, the insertion and removal of the cup 12 will be described.
The mounting structure of the heat insulating plate 13 is such that it is one step lower than the top surface of the base 2 in order to facilitate its mounting.
Therefore, when inserting or removing the cup 12, lift the handle 12a side diagonally to take it out, and then insert it diagonally. Therefore, the cup 1 is placed on the handle 9d side of the basket 9.
If there is a protrusion that obstructs the insertion and removal of the item 2, it will be inconvenient to use. Therefore, in the present invention, the overflow cylinder 9c is provided on the side opposite to the handle side of the basket 9, so that the operability of inserting and removing the cup 12 is not obstructed.

Furthermore, the basket 9 after removing the cup 12
Regarding dripping from the basket, the final point of dripping of coffee or tea is not constant, and for this reason, conventionally, after the cup is taken out, the drippings drip from the basket's outlet, staining the insulation board or leaving it on the floor. It was inconvenient because it was splattering. In the present invention, if the sliding plate knob 15b is operated to close the outflow port 9a with the water stop valve 11, the dripping problem is reliably eliminated and the above-mentioned inconvenience does not occur. In addition, with this invention, the residence time of hot water in the basket can be set arbitrarily, so even in the case of coffee, the residence time can be selected according to the amount of coffee powder, resulting in good taste and
You can adjust the extraction of scent etc.

As explained above, according to the present invention, both coffee and tea can be extracted with one basket.
It is economical because there is no need to prepare dedicated baskets for each as in the past. In addition, an adjustable water stop valve is installed at the liquid outflow part of the basket, so when brewing not only tea but also coffee, you can adjust the residence time of hot water according to the amount of coffee powder to achieve the desired taste, aroma, and color. etc. can be issued. Furthermore, it is possible to prevent water from dripping, and since it is equipped with a water tank for overflow, there will be no overflowing of water and will not pollute the surrounding area. Also,
Since the overflow tank is provided on the side where it does not interfere with the operation of putting in and taking out the cup, it has many advantages such as being very easy to use.
