Description

[Detailed explanation of the idea] This idea concerns a tea maker.

To make delicious black tea, use black tea leaves (hereinafter referred to as
It's called tea leaves. ) It is necessary to keep the extraction time to about 2 to 3 minutes. That is, if the extraction time is too short, the tea leaves cannot be opened sufficiently, while if the extraction time is too long, too much of the bitter and bitter components such as tannins will come out.

However, with conventional teapots, tea leaves and boiling water are placed in the pot to brew the tea, and the brewing time must be adjusted manually, making it difficult to brew black tea that has been brewed for the optimal amount of time. There was a drawback.

The object of this invention is to provide a tea maker that eliminates the above-mentioned drawbacks by providing a teapot and a tea extraction container, and by operating an on-off valve provided on the tea extraction container by a timer.

As mentioned above, this invention was devised as a tea maker for black tea, but it goes without saying that it can also be used as a tea maker for brewing green tea.

Examples 1 to 3 shown in the drawings will be described below. In addition, in these Examples, the same members are indicated by the same symbols.

Example 1 Example 1 is shown in FIGS. 1 and 2.

As shown in FIG. 1, a tea brewing container 3 is placed on top of a tea pot 1 having a handle 2 and having an open top. The tea extraction container 3 has a container main body 5 with a handle 4 and an open top surface, and an opening 7 is formed in the bottom wall 6 of the container main body 5, and an internally threaded cylinder 8 concentric with this opening 7 is formed. A bottom member 9 is detachably attached to the female threaded tube 8 by a male threaded portion 10. The bottom member 9 includes a horizontal wall 12 having an outlet 11 in the center, a cylindrical wall 13 integrally formed on the outer peripheral edge of the horizontal wall 12, a horizontal collar 14 integrally formed on the lower end of the horizontal wall 12, and an outer peripheral edge of the horizontal collar 14. a hanging peripheral edge 15 integrally formed with the outlet port 1;
1 and a guide tube 16 integrally formed in a hanging shape on the periphery of the guide tube 1. The male threaded portion 10 is formed on the upper outer periphery of the cylindrical wall 13, and the male threaded portion 1
An annular stepped portion 17 is formed next to the lower portion of the ring 0, with which the lower end of the female threaded tube 8 comes into contact.

The periphery of a dome-shaped filter 18 made of wire mesh, synthetic resin mesh, etc. is held between the horizontal wall 12 of the bottom member 9 and the periphery of the opening 7 via an annular packing 19 having a U-shaped cross section fitted therein. With the above configuration, the filter 18 can be removed by removing the bottom member 9 from the female threaded tube 8.
It goes without saying that the filter 18 may be attached to the lower end of the guide tube 16 or at the middle of its height. In short, the filter 18 may be mounted in any manner as long as it covers the outlet 11. The outflow port 11 is opened and closed by an on-off valve 21 that is movable up and down so as to come into contact with and move away from a valve seat 20 formed on its upper periphery. This on-off valve 21 is composed of a disk-shaped valve body 22 and a valve stem 23 provided in a hanging manner at the center thereof.The valve stem 23 is attached to a cylinder body 25 attached to a guide cylinder 16 via an arm 24. It is fitted. Further, the on-off valve 21 is always urged in a direction to close the outlet 11 by a resilient spring 26 fitted to the valve stem 23. Valve stem 23
The left end of a lever 27 that operates the on-off valve 21 is brought into contact with the lower end of the guide tube 16.
It protrudes to the outside of the bottom member 9 through the opening 28 of the bottom member 9 and the opening 29 of the cylindrical wall 13 . A gasket 30 is attached to the opening 28 to prevent the tea from flowing out through the gasket 30, and a slit 31 is formed in the gasket 30 to allow the lever 27 to swing up and down. The lever 27 is swingably attached to a bracket 32 via a pin 33 in the middle of its length, and the bracket 32 is provided on a horizontal plate 34 attached to the guide cylinder 16 and the cylindrical wall 13.

At the right end of the lever 27 is the rod 3 of the timer 35.

are formed, and fitting grooves 40, 40 into which the fitting protrusions 38, 38 fit are formed on both sides of the recess 39. With such a configuration, the fitting groove 40,
40 so that the fitting protrusions 38, 38 are fitted,
The timer 35 can be attached to the tea extraction container 3 by inserting the timer 35 into the recess 39, and can be removed by performing the reverse operation. A knob 41 is rotatably provided on the front wall of the casing 37 of the timer 35. A triangular indicator 42 is formed on the knob 41, and cooperates with the indicator 42 to indicate the set time or the state of the on-off valve 21. A scale 43 as shown is formed on the front wall of the casing 37. Of these scales 43, the scale corresponding to "O" is for indicating that the on-off valve 21 is in the open state, and the scale corresponding to "C" is for indicating that the on-off valve 21 is in the closed state. It is for "1""2"
The scale corresponding to "3" is for indicating the set time (minutes). The knob 41 is connected to the casing 37
It is fixed to a rotating shaft 44 inside, and this rotating shaft 44 is adapted to interlock with an automatic return device 45 having a built-in spring. Also, a cam 46 is attached to the rotating shaft 44.
A cam follower 47 at the upper end of the rod 36 is brought into contact with this cam 46 by the biasing force of a spring 48. The cam 4
6, as shown in FIG. 2, an arcuate portion 46a that does not raise or lower the rod 36, an inclined portion 46b that raises or lowers the rod 36, a recessed portion 46c that holds the rod 36 in a downwardly protruding state, and an inclined portion that raises or lowers the rod 36. The recessed portion 46e holds the rod 36 in a retracted state.

In the figure, 49 is the lid of the tea extraction container 3.

Next, a method of using the Tee Maker of Example 1 will be explained.

After placing the tea brewing container 3 on top of the tea pot 1, put a predetermined amount of tea leaves into the tea brewing container 3, turn the knob 41 of the timer 35 clockwise in FIG. 2, and set the indicator 42 to the desired time ( minutes)
Rotate it to the position shown. By this operation, the arcuate portion 46a of the cam 46 is brought into contact with the cam follower 47, so that the rod 36, which had been protruding downward because the cam follower 47 had been fitted into the recess 46c, is moved upward by the biasing force of the spring 48. Enter and exit. Therefore, the lever 27, which had been prevented from rotating counterclockwise by the rod 36, becomes free, and is rotated counterclockwise via the on-off valve 21 by the action of the spring 26, and accordingly, the on-off valve 21 moves against the valve seat 20. and closes the outlet 11.

Further, by rotating the knob 41, the spring of the automatic return device 45 is turned on, so when the force is removed from the knob 41, the knob 41 and the cam 46 are returned to their original state by the action of the spring, that is, the second In the figure, it is gradually rotated counterclockwise.

After that, a predetermined amount of hot water is poured into the tea extraction container 3.

By the way, since the cam 46 is rotated counterclockwise (FIG. 2) by the action of the automatic return device 45 as described above, after the set time has elapsed, the inclined portion 46b of the cam 46 moves to the cam follower 47.
, the rod 36 is pressed down against the force of the spring 48. Therefore, the rod 36 pushes open the on-off valve 21 via the lever 27, and the black tea in the tea brewing container 3 can be poured into the teapot 1 from the outlet 11. That is, tea leaves and black tea can be automatically separated after a set time.

Meanwhile, the cam 46 further rotates until the recessed portion 46c thereof contacts the cam follower 47, and then the force of the mainspring weakens and the cam 46 automatically stops. In this state, the indicator of the knob 41 will show the "O" scale.

By the way, if the on-off valve 21 is not automatically opened by the timer 35, it is advisable to set the indicator 42 of the knob 41 to the "C" scale. By doing so, the recess 46e of the cam 46 is brought into contact with the cam follower 47, the rod 36 is retracted, and the on-off valve 21 can be closed via the lever 27.
At this time, since the mainspring of the automatic return device 45 is not wound, the cam 46 does not move automatically and remains stopped, so that the on-off valve 21 also remains closed. To open the on-off valve 21, the knob 41 may be rotated clockwise in FIG. 2 to align the indicator 42 with the "O" scale.

It goes without saying that the timer 35 may be provided with an alarm such as a bell that operates when the on-off valve 21 opens.

Example 2 Example 2 is shown in FIGS. 3 to 5. As shown in FIG. 3, a spring 51 is attached to the lever 27 to bias it in a clockwise direction.
