[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a beverage manufacturing device that extracts the extract of powdered raw materials such as coffee or black tea using boiling water to obtain beverages such as coffee or black tea.

[Conventional technology] Methods for obtaining beverages by extracting the extract from powdered raw materials for coffee and tea using boiling water can be roughly divided into the espresso method (centrifugal method) and the drip method. The time required for
The flavor of the extracted beverage is different. Therefore, in recent years,
With one beverage extraction device, the user's time convenience,
Products that allow extraction by any of these methods to be selectively adopted depending on taste preference are now available and are becoming popular.

FIGS. 7 to 10 show the structure of this type of beverage manufacturing apparatus. Reference numeral 1 denotes a main body. A heating container 2 is provided above the inside of the main body 1. A heater 3 and a hot water supply pipe are provided at the bottom of the heating container 2. 4 is installed. A drive shaft 5 is provided in the center of the heating container 2, the lower end of the drive shaft 5 rotatably and watertightly penetrates the bottom of the heating container 2, and the rotating shaft of a motor 6 is connected to the penetrating end. This connection allows the drive shaft 5 to rotate in conjunction with the motor 6.
A collector 9 is provided at the top of the heating container 2,
The collector 9 integrally includes a cylindrical body 10, a liquid collecting gutter 11 extending over the outer periphery of the cylindrical body 10, and a discharge pipe 12 led out from a part of the liquid collecting gutter 11 and bent downward, The lower part of the cylindrical body 10 faces the inside of the heating container 2 concentrically, and a cup a is arranged below the discharge pipe 12. The upper surface of the collector 9 is open, a cover 14 is placed over the open part 13, and an extraction part 17 is formed between the cover 14 and the collector 9. The cover 14 is formed with a protrusion 15 that bulges upward in a portion facing the heating container 2, and a hot water supply port 16 is formed in the center of the upper surface of the protrusion 15.

Then, the heater 3 and motor 6 are energized. In response to this, the water in the heating container 2 is heated to become hot water, and the espresso extractor 18 rotates at high speed together with the drive shaft 5 in conjunction with the motor 6. Due to this rotation, the hot water in the heating container 2 is pumped up through the tapered pumping tube 20, and this hot water is diffused into the dish part 19 and permeates into the powdered raw material in the dish part 19 by centrifugal force. This osmosis extracts the coffee extract and produces coffee liquid as a beverage. And this coffee liquid is plate part 1
The liquid is ejected from the gap between the opening periphery of the collector 9 and the lid 21, flows into the liquid collection gutter 11 of the collector 9, and is further supplied from the liquid collection gutter 11 to the cup a through the discharge pipe 12. In this way, coffee liquid can be obtained by the espresso method.
Note that 14a is a protruding wall formed on the lower surface of the cover 14 to prevent the coffee liquid ejected from the espresso extractor 18 from spreading.

Next, we will discuss the case of obtaining coffee liquid using the drip method. In this case, remove the cover 14 from the top of the collector 9, pull out the espresso extractor 18 from the drive shaft 5, and replace it with the espresso extractor 18, as shown in FIGS. 9 and 10. Place extractor 25 on top of collector 9, cover again with cover 14,
Furthermore, a water tank 26 is placed and attached on top of this cover 14.

1 through the discharge pipe 12 into the cup a. In this way, coffee liquid can be obtained by the drip method.

[Problem that the invention attempts to solve]

When obtaining a beverage using the drip method as described above, the dripping tube 36 must be rotated to ensure that the dripping port 37 faces the hot water supply port 16.
Often, people forget to turn the dripping pipe 36 and start operation without the dripping port 37 facing the hot water supply port 16. In such cases, boiling hot water is discharged from the dripping port 37. There was a risk that the liquid would drip and scatter on the top surface of the main body 1 and its surroundings, resulting in accidental burns. This invention is aimed at solving these problems.

[Means for solving problems]

In order to solve these problems, this invention includes a main body having a brewing part, an espresso extractor that can be installed in the extracting part, a drip extractor that can be selectively replaced with the extractor, and a drip extractor that can be selectively replaced with the extractor. a removable cover that covers the extraction part and has a hot water supply port facing the extraction part; and a removable cover that is rotatably provided with respect to the main body, and the dripping port at the tip is connected to the hot water supply port based on the rotational operation of the cover. When performing drip extraction by installing a drip extractor in the above-mentioned extraction section, a water tank is installed on the above-mentioned cover, and the water in this water tank is In the water tank, the water tank is sized to cover the drip pipe, and the water tank is large enough to cover the drip pipe; The dripping tube is provided with a relief cavity that fits into the dripping tube only when the dripping tube is placed in a normal rotational position where the dripping port and the hot water supply port face each other. be.

[Effect]

If the drip tube is placed in a rotational position other than the normal one, this drip tube will get in the way when installing the water tank, and you will therefore notice that the drip tube is in the wrong position, and this will prevent it. This prevents the dripping tube from being left in an incorrect state and performing an extraction operation.

〔Example〕

An embodiment of this invention will be described below with reference to FIGS. 1 to 5. Note that the same functional parts as those of the conventional apparatus shown in FIGS. 7 to 10 are given the same reference numerals, and the explanation thereof will be omitted.

The water tank 26 is formed to have a size sufficient to cover the drip pipe 36. A circular guide cavity 40 corresponding to the protrusion 15 of the cover 14 and an elongated relief cavity 41 communicating with the guide cavity 40 are formed in the water tank 26. The water tank 26 is lowered in parallel from above the cover 14, and the guide cavity 40 is fitted into the protrusion 15 to be attached to the upper surface of the cover 14. The dripping port 37 is placed in the rotating position and the hot water supply port 1
6, the dripping tube 36 escapes into the relief cavity 41 as the water tank 26 descends, and the relief cavity 41 fits and matches the outer periphery of the dripping tube 36, whereby the water tank 26 can be attached, but if the drip tube 36 is not placed in the correct rotation position, the drip tube 36 will get in the way of lowering the water tank 26, and the water tank 26 will not be attached to the top surface of the cover 14. It has become difficult to wear them. Note that a water inlet 48 is provided on one side of the water tank 26.
A cap 49 is attached to the water inlet 48.

As shown in FIGS. 3 and 4, a recess 42 is formed in the upper surface of the main body 1 in parallel with the drip pipe 36, and one end of the hot water supply pipe 4 is connected to the lower end of the recess 42 via a check valve 43. is connected so that the check valve 43 prevents the hot water boiling in the water supply pipe 4 from flowing back. Inside the recess 42 is an outlet 3 of a water tank 26 attached to the top surface of the cover 14.
2 is removably inserted. An on-off valve mechanism 44 is provided at the outlet 32, and this on-off valve mechanism 4
4 is a valve rod 45 loosely inserted inside the outlet 32;
, a spring 46 that elastically biases the valve rod 45 downward, and a valve body 47 attached to the upper end of the valve rod 45. When the outlet 32 faces the inside of the recess 42, the valve is The lower end of the rod 45 is the recess 42
By contacting the bottom surface of the valve body 47, the valve rod 45 is pushed upward against the spring 46, and the valve body 47
is separated from the opening 32a at the upper end of the outlet 32,
This separation allows the water in the water tank 26 to flow into the opening 32.
a, flows through the passage 45a on the outer peripheral side of the valve rod 45, and further passes through the check valve 43 into the hot water supply pipe 4, and when the water tank 26 is removed, the outlet 32 flows into the recess 4.
2, the valve rod 45 is lowered by the biasing force of the spring 46, and the valve body 47 is moved into the opening 3.
2a, thereby preventing the water in the water tank 26 from flowing out. Note that 50 is an O-ring fitted around the outer periphery of the outlet 32.

The drip pipe 36 is connected to the outer periphery of the other end of the hot water supply pipe 4 through a packing 51 so as to be rotatable and movable up and down.
are arranged to face above the recess 42, and from this state, the drip tube 36 is lowered so that the drip port 37 can be exposed to the opening surface of the upper end of the recess 42.

When performing extraction by the drip method, the dripping tube 36 is rotated so that the dripping port 37 faces the hot water supply port 16 of the cover 14, and in this state, the water tank 26 is placed on the cover 14 and attached. However, at this time, if you forget to rotate the drip tube 36 and the drip tube 36 is not placed in the correct position, it will be difficult to install the water tank 26 as described above, and this will cause If the person notices the mistake in the placement of the drip tube 36 and places the drip tube 36 in the correct position, the brewing operation may be started while the drip tube 36 is left in the incorrect position. This avoids the danger of hot water dripping from the dripping port 37 of the dripping tube 36 onto the top surface of the main body 1 and its surroundings, and safety is maintained.

On the other hand, when extracting by the espresso method, first remove the water tank 26 from above the cover 14, then rotate the dripping tube 36 to retract it from above the cover 14, and leave it in this state. The cover 14 is removed, the drip extractor 25 of the extraction part 17 is replaced with the espresso extractor 18, the powdered raw material is stored in the espresso extractor 18, and the water is stored in the heating container 2. A cover 14 is then put on. Dripping tube 36
When retracting from above the cover 14, as shown in FIG. Face the inside of the opening. With such measures, even if the water remaining in the hot water supply pipe 4 boils and drips from the dripping port 37 during the espresso extraction operation, it will not flow into the hot water supply pipe 4 from the recess 42. There is no risk of it returning and scattering onto the top surface of the main body 1 or its surroundings. Moreover, the lowering of the dripping tube 36 reduces the overall height of the beverage manufacturing apparatus, which is advantageous in terms of transportation and storage.

By the way, when extracting by the espresso method, in the conventional configuration shown in FIG. 7, when the espresso extractor 18 rotates at high speed,
A turbulent air flow occurs in the space s above the espresso extractor 18, and the wind pressure caused by this turbulence causes a part of the beverage ejected from the espresso extractor 18 to become turbulent and fly around to the back side of the protruding wall 14a, causing the collector 9 Therefore, in this embodiment, as shown in FIG.
The upper surface and peripheral surface of the espresso extractor 18 are covered with a hood 52 with a slight interval therebetween. With this configuration, the coffee liquid spouted from the espresso extractor 18 is neatly transferred to the collector 9.
This allows the liquid to flow into the liquid collection gutter 11, and as a result, the conventional protruding wall 14a becomes unnecessary, and the molding of the cover 14, etc. can be carried out advantageously.

Further, as shown in FIG. 6, while an eccentric cam 53 is attached to the outer peripheral surface of the vertical portion of the dripping tube 36, a micro switch 54 corresponding to this eccentric cam 53 is attached.
When extracting using the drip method,
When the drip tube 36 deviates from its normal rotational position, the drip system operation circuit is held open via the micro switch 54, and the drip tube 36
It is also possible to add a safety switch mechanism that allows operation by the drip method only when the valve is placed in the normal rotation position.

[Effect of idea]

As explained above, according to this invention, there is no possibility that the extraction operation will be started under the incorrect condition where the dripping tube is placed in a rotational position other than the normal one. This has the effect of preventing the risk of burns caused by dripping and splashing of boiling water on the top surface of the main body and its surroundings, thereby maintaining safety.
