A heat retaining plate 6 is provided on the upper surface of the lower side protruding portion, and a decanter 7 for receiving the extracted coffee liquid is placed on the heat retaining plate 6.

The filter 2 comprises a basket 20 having an extraction port 21 for dropping coffee at the lowest position on the bottom wall, and ground coffee beans 22 are put into a paper filter 23. And is stored in the basket 20.

Then, hot water is supplied to the basket 20 from the sprinkling port 5 of the main body 1 to extract the coffee liquid, the extracted coffee liquid passes through the paper filter 23, and then passes through the extraction port 21 to stay on the heat insulating plate 6. It enters the decanter 7 and is stored here. When drinking coffee, remove the decanter 7 from the heat insulating plate 6 and transfer it to the coffee cup.

However, in the above-described filter 2, after the coffee extraction, the coffee liquid impregnated in the coffee beans 22 and the paper filter 23 passes through the extraction port 21 when the decanter 7 is removed from the heat insulating plate 6. There was a problem that the heat insulating plate 6 was dropped on the heat insulating plate 6 to stain the heat insulating plate 6. In addition, when the basket 20 is removed from the main body 1 and placed on a table or floor after the extraction, there is a problem that the coffee liquid drips and stains the placement surface.

Therefore, in order to solve such a problem, there is a filter 30 in which a liquid leakage prevention valve 31 described later is provided on the bottom surface of the bottom wall of the basket 20.

The filter 30 will be described with reference to FIG.

The filtering machine 30 is provided with a liquid leakage prevention valve 31 at the extraction port 21 of the basket 20 for opening and closing the extraction port 21.

The liquid leakage prevention valve 31 is provided with a rubber packing 32 at one end and a spring 33 for biasing the rubber packing 32 toward the extraction port 21 side of the basket 20 at the other end. The prevention valve 31 is pivotally supported on the lower surface of the bottom of the basket 20 with the center as a fulcrum.

Further, the liquid leak prevention valve 31 prevents the liquid leak by preventing a part of the lid of the decanter 7 from coming into contact with the liquid leak preventive valve 31 when the decanter 7 is placed on the heat insulation plate 6. The rubber packing 32 of the valve 31 is adjusted so as to be opened from the extraction port 21 of the basket 20.

When the decanter 7 is placed on the heat retaining plate 6 before the hot water is supplied from the sprinkling port 5 of the main body 1 to the basket 20 and the coffee liquid is extracted, a part of the lid of the decanter 7 is removed. The rubber packing 32 of the liquid leakage prevention valve 31 opens the extraction port 21 of the basket 20 in contact with the liquid leakage prevention valve 31, and the coffee liquid is extracted from the basket 20 into the decanter 7.

When the coffee liquid is completely extracted into the decanter 7, and when the decanter 7 is removed from the heat retaining plate 6, a part of the lid of the decanter 7 separates from the liquid leakage prevention valve 31 to prevent the liquid leakage. The spring 33 of the valve 31 biases the rubber packing 32 against the extraction port 21 of the basket 20 to close the extraction port 21.

As described above, when the decanter 7 is removed from the heat insulating plate 6 or when the basket 20 is removed from the main body 1 and placed on another place, the coffee liquid is extracted from the extraction port 21 of the basket 20. Are configured to not leak.

[0017]

[Problems to be solved by the device]

 However, the above-described filter having the liquid leakage prevention valve on the bottom surface of the bottom wall of the basket has the following problems.

That is, since the liquid leakage prevention valve is opened and closed by attaching and detaching the decanter to and from the heat insulating plate, it is necessary to use a decanter in which a part of the decanter lid is in good contact with the liquid leakage prevention valve. That is, if the decanter is placed on the heat insulation plate with the lid removed, or if the lid is damaged or lost, the liquid leakage prevention valve cannot be used.

Further, the rubber packing provided in the liquid leakage prevention valve is often clogged or damaged and requires replacement, which is troublesome.

In addition, since the packing extracts coffee into the decanter under the basket while spraying the coffee liquid from the extraction port of the basket and sprinkling the water radially even when extracting the coffee liquid, it is necessary to enlarge the receiving port of the decanter lid. In addition, the rubber packing must be kept clean at all times.

In addition, since the legs are not provided on the lower surface of the bottom wall of the basket of the device provided with the valve, there is a drawback that the stability is poor.

However, if the liquid leakage prevention valve is not provided on the lower surface of the bottom wall of the basket and the legs are provided on the lower surface, when the decanter is inserted into the heat insulating plate from the front or on the heat insulating plate. The decanter's head was caught on the leg of the basket when it was taken out from the basket, and the operability of taking in and out the decanter was poor. In particular, it was impossible to put in and take out the decanter left and right.

It is an object of the present invention to provide a beverage brewing device that does not leak liquid or has improved workability in inserting and removing a decanter.

[0024]

One end of an inverted L-shaped water supply pipe 13 is connected to the water supply tank 11. The other end of the water supply pipe 13 is opened at the lower end of the water heating tank 3 so that the water contained in the water supply tank 11 is fed to the lower end of the water heating tank 3. Further, the other end of the hot water supply pipe 9 and the sprinkler 16 are connected to the upper surface of the bottom wall of the upper right protruding portion via a joint portion 14. A through hole 15 is provided in a connecting portion between the sprinkler 16 and the joint portion 14, and a plurality of hot water sprinkling ports 5 are formed in a bottom wall of the sprinkler 16.

A heat insulating plate 6 is provided on the upper surface of the lower right protruding portion, and a decanter 7 is placed on the heat insulating plate 6.

The filter 41 according to the present invention is detachably attached below the upper right protruding portion. The filter 41 comprises a basket 50 made of a synthetic resin molded product having an open upper end and an obliquely closed bottom 50 toward the lower end. The basket 50 has an extraction port 51 protruding at the lowest position on the bottom surface of the bottom wall. Has been formed. At the center of the inner surface of the bottom wall of the basket 50, as shown in FIG. 2, there is provided a cylindrical portion 52 that is narrowed from the upper side to the lower side, and communicates with the extraction port 51 of the bottom wall of the basket 50. ing. Further, the outer peripheral wall of the cylindrical portion 52 is also used as a bank so that the coffee liquid that has dripped into the basket 50 does not suddenly flow downward from the extraction port 51.

Further, through the extraction port 51 of the basket 50, there are provided a cylindrically-shaped floating portion 53 having a closed top end and an opened bottom end, and protruding portions having left and right ends protruding upward. A liquid leakage prevention device 57 is provided by connecting the anchor-shaped locking portion 54 and a shaft 56 having a valve 55 at the center.

Further, since the valve 55 closes the extraction port 51 of the basket 50 with the inner surface of the cylindrical portion 52 provided on the inner surface of the bottom wall of the basket 50, it is formed in a conical shape that becomes smaller from the upper side to the lower side. There is.

In addition, the liquid leakage prevention device 57 pushes inward the protrusions that protrude to the left and right of the anchor-shaped locking portion 54, and pulls up the liquid leakage prevention device 57 from above to pull up the basket 50. It can be removed from the extraction port 51 of.

Further, the anchor-shaped locking portion 54 of the liquid leakage prevention device 57 in the state where the conical valve 55 of the liquid leakage prevention device 57 is closed by the inner surface of the cylindrical portion 52 removes the basket 50 from the main body 40. It is set to a length such that a gap Y can be provided from the mounting surface by legs 60, which will be described later, provided on the lower surface of the bottom wall of the basket 50 even when the basket 50 is mounted on another place. Further, a plurality of ribs 58 are formed on the inner surface of the basket 50 so as to prevent the paper filter 23 from adhering to each other in a radial state.

Next, the operation of the liquid leakage prevention device 57 of the present invention will be described with reference to FIGS. 3, 4 and 5.

First, the ground coffee beans 22 are put into the paper filter 23 and stored in the basket 50. Next, the decanter 7 is placed on the heat insulating plate 6 and the water heating tank 3 is filled with water. When the water in the water heating tank 3 is heated to a predetermined temperature by the heater 4, the lid 12 of the water supply tank 11 is opened and the water is supplied into the water supply tank 11. The water is sent to the lower end of the water heating tank 3 through the water supply tank 11, and as a result, the hot water in the water heating tank 3 enters the water sprayer 16 from the hot water outlet 8 through the hot water supply pipe 9. The water is sprinkled on the coffee beans 22 from the sprinkling port 5.

The hot water sprinkled from the sprinkling port 5 is applied to the coffee beans 22, passes through the paper filter 23 to extract the coffee liquid, and is collected on the bottom surface of the basket 50 as shown in FIG. Then, when the coffee liquid is accumulated up to the upper portion of the cylindrical portion 52 on the inner surface of the bottom wall of the basket 50 (position W), the conical valve 55 of the liquid leakage prevention device 57 is in close contact with the inner surface of the cylindrical portion 52, so that extraction is performed. The mouth 51 is closed by the valve 55, and the inside of the opening of the floating portion 53 provided at the upper end of the liquid leakage prevention device 57 is closed by the valve 55 and the coffee liquid, and air is collected.

Further, when the coffee liquid is dripped into the basket 50 through the paper filter 23 and the water level rises (position V), buoyancy of the air in the floating portion 53 is generated and the floating portion 53 rises. To do. That is, from the distance Z from W to V, the floating portion 53 of the liquid leakage prevention device 57 does not float due to the weight of the liquid leakage prevention device 57.

As a result, the valve 55 is also separated from the inner surface of the cylindrical portion 52, so that the extraction port 51 of the basket 50 is opened and the coffee liquid is prevented from leaking from the liquid leakage prevention device 57 from the extraction port 51 as shown in FIG. It is extracted into the lower decanter 7 along the locking portion 54.

In the above-described state, the relationship between the amount of hot water supplied from the sprinkler port 5 and the amount of discharge from the extraction port 51 of the basket 50 is that the amount of hot water supply is greater than the amount of discharge (hot water supply amount> discharge amount). The water level in the basket 50 rises, and the float 53 also rises in accordance with the water level.

However, since the anchor-shaped locking portion 54 is provided below the liquid leakage prevention device 57, the floating portion 53 is blocked by the conical valve 55 within the height H of the rib 58. It is possible to freely move up and down only within the range X of the position where the locking portion 54 abuts the lower surface of the extraction port 51 of the basket 50 from the position in the open state. Further, the anchor-shaped locking portion 54 is also moved by the distance X ′ from the position in which it is closed by the valve 55 to the position where the anchor-shaped locking portion 54 contacts the lower surface of the extraction port 51 of the basket 50. I can't.

Next, when the discharge amount becomes larger due to the relationship between the discharge amount from the extraction port 51 of the basket 50 and the hot water supply amount from the sprinkler port 5 (hot water supply amount <discharge amount), the water level in the basket 50 decreases. Begin to. When the water level continues to descend to the same height as the upper surface of the floating portion 53, the buoyancy of the floating portion 53 balances with the water level, and the floating portion 53 starts to descend according to the water level.

In this way, when the water level of the coffee liquid descends to the position of V, the floating portion 53 also descends in accordance with the water level, and at the same time, the liquid leakage prevention device 57 descends downward by its own weight and reaches the position of W. When is lowered, the conical valve 55 of the liquid leakage prevention device 57 comes into close contact with the inner surface of the cylindrical portion 52, so that the extraction port 51 is closed by the valve 55.

After that, some of the water remaining in the coffee beans 22 continues to drip through the filter 23, so that the water level of the coffee liquid accumulated on the bottom surface of the basket 50 rises.

However, when the water level is at the V position, that is, from the distance W to the distance Z, the floating portion 53 does not float due to buoyancy because the dead weight of the liquid leakage prevention device 57 is large. When the decanter 7 is removed, or when the basket 50 is removed from the main body 40 and placed on another place, the extraction liquid of the basket 50 remains in the state and remains on the bottom surface of the inner wall of the basket 50. The coffee fluid does not leak downward via 51.

Next, the legs 60 provided on the bottom surface of the bottom wall of the basket 50 will be described with reference to FIGS. 6 (a) and 6 (b).

Three legs 60 are provided at the end of the bottom surface of the bottom wall of the basket 50, and the legs 60 are provided at positions such that connecting each leg 60 with a line forms an equilateral triangle.

The leg 60 is a plate-shaped member made of resin with a rounded lower part, and an upper part is a side T-shaped support part 61 provided with protrusions perpendicular to the plate surface in the front and rear direction, and a spring member. 62.

One end of the spring member 62 of the leg 60 is attached to the upper wall of the leg storage portion 63 provided at the end of the bottom surface of the bottom wall of the basket 50, and the other end is connected to the upper end portion of the support portion 61. Has been. Further, inside the leg accommodating portion 63, guide portions 64 are provided on the left and right sides of the accommodating portion 63 so that the supporting portion 61 vertically moves up and down.

Further, the spring member 62 is set to have a strength such that the spring member 62 does not contract when the basket 50 is placed on it (even if it contains coffee ingredients).

Thus, when the basket 50 is attached to the main body 40 and the decanter 7 is inserted or taken out, the spring member 62 of the leg 60 extends and the supporting portion 61 projects from the leg accommodating portion 63. When the head of the decanter 7 is pressed along the rounded portion below the support portion 61, the spring material 62 of the leg 60 is compressed along the guide portion 64, and the support portion 61 is moved to the leg storage portion 63. When the decanter 7 is placed on the heat insulation plate 6 or is taken out, the leg 60 returns to the state of being projected from the leg storage portion 63.

As a result, it is possible to take in and out from the side or diagonal, which was impossible with the conventional one.

Further, as a leg 70 of another embodiment, instead of the leg 60 composed of the support portion 61 and the spring material 62, a plate-like support portion 7 having elasticity at the end of the bottom wall of the bottom wall of the basket 50. Attach 1. On the lower surface of the basket 50, there is provided a storage portion 72 having a size capable of storing the elastic plate-shaped support portion 71. (See FIGS. 7 (a) and 7 (b)) When the basket 50 is detached from the main body 40 and placed, the basket 50 has elasticity due to its own weight (even if it contains coffee ingredients). The strength of the plate-shaped support portion 71 is set so as not to bend.

Thus, when the basket 50 is attached to the main body 40 and the decanter 7 is inserted, the head of the decanter 7 comes into contact with the elastic plate-shaped support portion 71. Since the elastic plate-shaped support portion 71 is bent and is stored in the support portion storage portion 72, the decanter 7 can be easily stored, and when the decanter 7 is taken out, the decanter 7 Since the head portion contacts the support portion 71 and the support portion 71 bends outward, the decanter 7 can be easily taken out.

[0059]

[Effect of device]

 As described above, according to the present invention, the floating portion of the liquid leakage prevention device provided through the extraction port provided on the bottom wall of the basket rises and falls depending on the amount of coffee liquid dropped into the basket. , The valve connected to the floating part moves according to the floating part to adjust the opening and closing of the extraction port of the basket, so when removing the decanter from the main body or removing the basket from the main body. Coffee liquid does not leak from the extraction port of the basket and does not stain the heat insulating plate or mounting surface.

Further, since the liquid leakage prevention device is provided inside the basket, it is not necessary to use a decanter suitable for the basket.

Since no rubber packing is used in the liquid leakage prevention device, replacement due to cracks, etc. does not occur, and since coffee liquid does not flow to the decanter through the rubber packing, there is no scattering from the basket and the decanter lid There is no need to increase the size of the socket.

Since the legs provided at the end of the bottom surface of the bottom wall of the basket are designed to be stored or bent, when the decanter is placed on the heat retaining plate from the front, side, or diagonal, or Even if the decanter head comes into contact with the leg when taking it out from the heat retaining plate, the leg is stored or bent, so that the leg does not get in the way.
