The present invention relates to a coffee maker.

Coffee makers are known to extract coffee from coffee powder made by grinding coffee beans. When using such a coffee maker, it is necessary to supply water to the coffee maker and heat the water to a predetermined temperature to make hot water.

As a configuration for supplying water to the coffee maker, the main body is equipped with a detachable water supply tank and a water supply pipe connected to the water supply tank, and hot water is heated by heating the water in the water supply pipe with the heater built in the main body. The structure to be obtained (for example, Patent Document 1: JP-A-5-64615) is known. Further, there is also a configuration of a coffee maker having a water supply tank and a water boiling tank separate from the water supply tank and supplying water to the water boiling tank to obtain hot water (for example, Patent Document 2: Japanese Patent Application Laid-Open No. 2001-29237). Are known.

Japanese Unexamined Patent Publication No. 5-64615 Japanese Unexamined Patent Publication No. 2001-29237

The coffee maker disclosed in Patent Document 1 heats the water in the water supply pipe to obtain hot water. Therefore, although the mechanism is simple, it is not possible to obtain a sufficient amount of hot water in a short time when supplying the coffee powder, and it is difficult to finely control the amount of hot water supplied to the coffee powder. , There is a problem that the time required to complete the extraction of coffee becomes long.

Further, since the coffee maker disclosed in Patent Document 2 has a water supply tank and a water boiling tank, the coffee maker becomes large and the structure becomes complicated. Further, since the hot water in the boiling tank is supplied to the coffee powder by being pushed out by the water in the water supply tank, it is difficult to supply the hot water to the coffee powder in an appropriate amount and timing. There is. Further, there is a problem that the heater or the like provided in the water boiling tank becomes an obstacle and cleaning becomes difficult.

Therefore, the present invention has been made to solve the above problems, and the object thereof is as follows. That is, sufficient hot water can be obtained in a short time when extracting coffee from coffee powder, and it is possible to supply the coffee powder with an appropriate temperature and amount at an appropriate timing, and it is compact and simple. It is an object of the present invention to provide a coffee maker having a simple structure, capable of extracting coffee in a short time, easy to clean, and capable of continuous hygienic use.

As a result of diligent research by the inventor of the present application in order to achieve the above object, a water storage tank with a heater that can be attached to and detached from the main body is adopted, and the water in the water storage tank is heated by the heater integrally attached to the water storage tank. We came up with a configuration in which a sufficient amount of hot water is prepared in advance, and the hot water in the water storage tank is sucked up by a pumping pipe to supply hot water at an appropriate temperature to the coffee powder at an appropriate timing.

That is, the present invention includes a water storage tank, a heater integrally attached to the water storage tank and heating the water in the water storage tank to a predetermined temperature, a pumping pipe for pumping water in the water storage tank, and the heater.

As a result, sufficient hot water can be obtained in a short time when extracting coffee from coffee powder, and it is possible to supply hot water at an appropriate temperature and amount to the coffee powder at an appropriate timing, and it is compact and compact. Coffee can be extracted in a short time with a simple structure. In addition, since the water storage tank has a simple structure in which a heater is integrally attached, the water storage tank can be easily cleaned, so that it can be used continuously and hygienically.

Further, a link portion rotatably supported inside the main body is provided, and the advancing / retreating movement mechanism is connected to the link portion and the pumping pipe is fixed to the link portion. Depending on the position of the mechanism, it is preferable that the pumping pipe moves back and forth between the inside of the water storage tank and the outside of the water storage tank.

As a result, when the water storage tank is attached to or detached from the main body, the pumping pipe that has entered the water storage tank can be discharged to the outside of the water storage tank simply by pulling out the advancing / retreating movement mechanism from the main body. Therefore, the pumping pipe does not get in the way and the water storage tank can be easily removed from the main body. In addition, cleaning of the water storage tank becomes easier.

Further, it is preferable that the water storage tank has a closing plate attached to the link portion and formed so as to be able to close the upper surface opening of the water storage tank, and the pumping pipe is arranged so as to penetrate the closing plate. ..

As a result, it is possible to prevent the steam generated from the hot water in the water storage tank from being released to the inside of the main body, and prevent the power supply unit and the like arranged inside the main body from being damaged by steam (steam) and dew condensation. can do.

Further, it is preferable that the water storage tank is provided with a sealing packing that seals between the closing plate and the closing plate when the closing plate closes the upper surface opening.

As a result, it is possible to more reliably prevent the release of water vapor generated from the hot water in the water storage tank to the inside of the main body.

Further, the upper surface opening is a long hole that opens to a position outside the moving position of the lower end of the pumping pipe in a plan view, and the sealing packing is erected along the outer peripheral edge of the long hole. It is preferable that it is.

As a result, the opening area of the upper surface opening can be made as small as possible, the heat retention of the hot water in the water storage tank can be improved, and the water vapor generated from the hot water in the water storage tank is released inside the main body. Can be prevented more reliably.

Further, the link body constituting the link portion is preferably formed of a basic cylinder body and a small diameter cylinder body or a rod body housed inside the basic cylinder body.

As a result, the structure of the link portion arranged inside the main body can be made compact and simple, so that the miniaturization of the coffee maker can be promoted.

Further, the main body is provided with an erroneous insertion prevention member that regulates the entry of the water storage tank into the inside of the main body when at least one of the water storage tank is displaced in the height direction or the lateral direction. Is preferable.

This makes it possible to avoid problems such as damage caused by the water storage tank colliding with a part of the main body and spillage of water or hot water in the water storage tank when the water storage tank is introduced into the main body. Further, since the electric connection between the heater attached to the water storage tank and the power supply connector can be ensured, the power can be reliably supplied to the heater.

Hereinafter, embodiments of the coffee maker according to the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, the coffee maker 100 in the present embodiment has a basic configuration in which the water storage tank 20 to which the heater 10 is integrally attached is detachable from the main body 30. The water storage tank 20, the advancing / retreating moving mechanism 40 for advancing / retreating the water storage tank 20 to the inside and the outside of the main body 30, the pumping pipe 50, the advancing / retreating moving mechanism 40 are connected to the main body 30, and the pumping pipe 50 is attached. A link unit 60, a hot water supply pump 70, a power supply unit 80 that supplies power to the heater 10 and the hot water supply pump 70, and a coffee extraction unit 90 are arranged, respectively. In this embodiment, a dripper that can be attached to and detached from the main body 30 is used as the coffee brewing unit 90.

As shown in FIGS. 1 to 5, the heater 10 is integrally attached to the bottom of the water storage tank 20 together with the water storage tank 20, and constitutes the bottom of the water storage tank 20. The inner bottom surface of the water storage tank 20 is formed on a heating surface by the heater 10, and the water in the water storage tank 20 can be heated to a predetermined temperature. Since the heater-side power supply connector 12 for power supply is arranged on the outer bottom surface of the heater 10, the heater-side power supply connector 12 is exposed on the outer bottom surface of the water storage tank 20. Here, a recess is formed on the outer bottom surface of the water storage tank 20, and the heater side power supply connector 12 is exposed on the inner bottom surface of the recess. The heater-side power supply connector 12 formed in this way is engaged with the power supply-side power supply connector 42 that is electrically connected to the power supply unit 80 and is arranged so as to protrude from the upper surface of the advancing / retreating movement mechanism 40. It is possible to remove it.

The water storage tank 20 in the present embodiment is formed in a rectangular parallelepiped shape with an open upper surface, and a lid 22 is detachably attached to the upper surface. The lid 22 is provided with an elongated hole 24 which is an opening on the upper surface of the water storage tank 20. By forming the upper surface opening with such elongated holes 24, the opening area of the upper surface opening of the water storage tank 20 can be made as small as possible, and the heat retention of hot water in the water storage tank 20 can be improved. It is convenient in that respect.

In the present embodiment, the sealing packing 26 is erected at a required height along the outer peripheral edge of the elongated hole 24. The sealing packing 26 is preferably made of a material having high elasticity, water resistance and heat resistance, such as synthetic rubber and silicone rubber. Further, as shown in FIGS. 4 and 5, the sealing packing 26 is preferably formed in a so-called funnel shape in which the upper end portion, which is the contact portion with the closing plate 52, is curved to the outside of the elongated hole 24. It is more preferable that the contact portion with the closing plate 52 is formed to be a horizontal plane.

The hot water produced in the water storage tank 20 formed in this way is connected to the hot water supply pump 70 and the hot water supply nozzle 72 by the operation of the advancing / retreating movement mechanism 40 and the link portion 60 from the elongated hole 24 as the upper surface opening. It can be supplied to the coffee extraction unit 90 by advancing and retreating the pumping pipe 50.

The required portion on the outer surface of the main body 30 (here, the required portion on the front surface) constitutes a part of the advancing / retreating movement mechanism 40, and is formed so as to be detachable from the outer surface of the main body 30. As shown in FIGS. 6 to 8, the advancing / retreating moving mechanism 40 in the present embodiment is arranged along the depth direction of the main body 30 inside the wall portion 40A and the main body 30 which are a part of the outer surface of the main body 30. It is formed by two slide rails 40B and a mounting portion 40C attached to the slide rails 40B. Further, since the slide rail 40B having a multi-stage structure is adopted in the present embodiment, the slide amount of the water storage tank 20 by the advancing / retreating movement mechanism 40 can be increased. This is convenient because the water storage tank 20 can be pulled out to the outside of the main body 30 to a position where the main body 30 does not get in the way when engaging and disengaging the water storage tank 20 and the advancing / retreating movement mechanism 40.

As shown in FIG. 8, a power supply connector 42 on the power supply side, which is electrically connected to the power supply unit 80, is projected from the upper surface of the mounting portion 40C attached to the slide rail 40B. The power supply side power supply connector 42 formed in a convex shape is formed so as to be matable with the heater side power supply connector 12 (see FIG. 5) of the water storage tank 20 formed in a concave shape. Further, the mounting portion 40C (water storage tank 20) is temporarily fixed to the main body 30 on the front surface when the mounting portion 40C is allowed to enter the inside of the main body 30 and on the inner surface of the main body 30 facing this surface. A catch mechanism 44 for this purpose is provided. The catch mechanism 44 in the present embodiment uses a push-catch type mechanism, but the catch mechanism 44 is not limited to the push-catch type, and other known configurations such as a ball-catch type shall be adopted. Can be done.

The link portion 60, which rotates inside the main body 30 by the advance / retreat operation of the water storage tank 20, has two link bodies 62, 63 and the rotation supported by the main body 30 by connecting them in an L shape. It is formed by a shaft portion 64. The rotating shaft portion 64 is rotatably supported around an axis (around the horizontal axis) orthogonal to the direction in which the water storage tank 20 moves back and forth between the inside and the outside of the main body 30 and in the horizontal direction.

One of the two link bodies 62 and 63 in the present embodiment has a small diameter that is housed inside the basic cylinder 62A and the basic cylinder 62A and can slide in the longitudinal direction of the basic cylinder 62A. It has a cylinder 62B. The other link body 63 is formed of a tubular body or a rod body. In the present embodiment, one link body 62 is composed of a basic cylinder body 62A and a small diameter cylinder body 62B, but the small diameter cylinder body 62B is a small diameter rod body having the same outer diameter dimension of the small diameter cylinder body 62B (not shown). It can also be. Further, one link body 62 can be formed by three or more cylinders or cylinders and rods, and the other link 63 can also be formed by connecting a plurality of cylinders or cylinders and rods. It can also be formed.

In one link body 62 in the present embodiment, the tip on the side of the basic cylinder 62A is rotatably connected to the mounting portion 40C, and the tip on the side of the small diameter cylinder 62B is rotated to the rotation shaft portion 64. It is movably connected. Since the lengths of the basic cylinder 62A and the small diameter cylinder 62B are formed to be about the same, one of the link bodies 62 can have a large difference in length between the shortest state and the longest state. Here, even if one of the link bodies 62 is in the longest state, the basic cylinder body 62A and the small diameter cylinder body 62B overlap within the required length range, so that the tip portions of the overlapping portions are particularly prevented from coming off. There is no need to process it.

Further, the other link body 63 is formed so that one end is fixed to the rotating shaft portion 64 and the upper surface opening (long hole 24) of the water storage tank 20 can be closed at the other end. The closing plate 52 is attached. When the closing plate 52 closes the elongated hole 24 of the water storage tank 20, the sealing packing 26 erected along the elongated hole 24 abuts in an elastically deformed state to form an opening on the upper surface of the water storage tank 20. Can be closed in a sealed state. Since the sealing packing 26 in the present embodiment is made of a highly elastic material and is formed in a funnel shape in which the contact surface with the closing plate 52 is a horizontal plane, the sealing property with the closing plate 52 is extremely high. be able to.

The closing plate 52 is provided with through holes 54 penetrating in the plate thickness direction at two locations, and the pumping pipe 50 is arranged in the closing plate 52 with the pumping pipe 50 and the temperature sensor 56 inserted through the through holes 54. It is set up. The temperature sensor 56 is connected to an operation control unit (not shown), monitors the water temperature in the water storage tank 20, and the operation control unit controls the operation of power supply to the heater 10 by the power supply unit 80. The through hole 54 is aligned so that the closing plate 52 is located within the range where the long hole 24 is formed in the state where the long hole 24 formed in the lid 22 of the water storage tank 20 is closed. It is formed.

As shown in FIGS. 6 and 7, the link portion 60 retracts the closing plate 52 from the lid 22 of the water storage tank 20 in a state where the water storage tank 20 mounted on the advancing / retreating movement mechanism 40 is retracted to the outside of the main body 30. The pumping pipe 50 and the temperature sensor 56 are separated from each other, and the pumping pipe 50 and the temperature sensor 56 are retracted from the inside of the water storage tank 20. Similarly, the link portion 60 is formed on the lid 22 of the water storage tank 20 in a state where the water storage tank 20 mounted on the advancing / retreating movement mechanism 40 is allowed to enter the inside of the main body 30 as shown in FIGS. 9 and 10. The elongated hole 24 is closed by the closing plate 52, and the pumping pipe 50 and the temperature sensor 56 are brought into the water storage tank 20 from the elongated hole 24 portion.

In this way, the pumping pipe 50 and the temperature sensor 56 move back and forth between the inside of the water storage tank 20 and the outside of the water storage tank 20 according to the position of the advancing / retreating movement mechanism 40 with respect to the main body 30 by the link portion 60. Similarly, the link portion 60 switches between a closed state and a non-closed state of the elongated hole 24 as the upper surface opening formed in the lid 22 of the water storage tank 20 by the closing plate 52 according to the position of the advancing / retreating movement mechanism 40 with respect to the main body 30. Is going.

The elongated hole 24 formed in the lid 22 of the water storage tank 20 in the present embodiment opens to a position outside the moving position in the plan view of the pumping pipe 50 and the lower end of the temperature sensor 56 by the advancing / retreating moving mechanism 40 and the link portion 60. I'm letting you. As a result, even if the pumping pipe 50 and the temperature sensor 56 are rotated by the advancing / retreating movement mechanism 40 and the link portion 60, the tip of the pumping pipe 50 does not get caught in the lid 22 and the inside of the water storage tank 20 is formed in the elongated hole 24. You can surely move in and out of the outside.

Further, an erroneous insertion prevention member 92 (see FIG. 1) is arranged inside the main body 30 in the present embodiment. The erroneous insertion prevention member 92 is arranged at the boundary portion of the movement path of the water storage tank 20 when the water storage tank 20 enters the inside of the main body 30. If the lid 22 is normally attached to the water storage tank 20 and the advancing / retreating movement mechanism 40 is correctly attached, the erroneous insertion prevention member 92 does not get in the way and the water storage tank 20 can enter the inside of the main body 30. Can be done. On the other hand, when the water storage tank 20 (or the lid 22) is displaced in at least one of the height direction and the lateral direction, the water storage tank 20 (or the lid 22) comes into contact with the erroneous insertion prevention member 92, and the water storage tank 20 The entry into the inside of the main body 30 is restricted.

Therefore, when the lid 22 is incompletely attached to the water storage tank 20, the engagement state between the heater side power supply connector 12 and the power supply side power supply connector 42 is incomplete, or the water storage tank 20 and the mounting portion 40C The water storage tank 20 in a so-called improper state, such as when a foreign object is caught between the two, is prevented from entering the inside of the main body 30 by the erroneous insertion prevention member 92. As a result, problems such as the inability to pull out the water storage tank 20 from the inside of the main body 30, the inability to supply power to the heater 10, and the discharge of water vapor from the water storage tank 20 into the main body 30 occur. It is convenient in that it can be prevented.

Next, an example of the operation of the coffee maker 100 in this embodiment will be described. The user sets a filter paper as a filtering means in the dripper as the coffee brewing unit 90, puts coffee powder as appropriate, and sets a container 94 represented by a coffee server at the outlet of the coffee brewing unit 90. Subsequently, as shown in FIGS. 6 and 7, the user pulls out the advancing / retreating moving mechanism 40 and pulls out the water storage tank 20 from the inside of the main body 30. At this time, one link body 62 connected to the advancing / retreating movement mechanism 40 rotates while extending, the link portion 60 (rotating shaft portion 64) is rotated, and the closing plate attached to the other link body 63. The 52 is separated from the lid 22 of the water storage tank 20. As a result, the pumping pipe 50 and the temperature sensor 56 are retracted from the upper surface opening (long hole 24) of the water storage tank 20, so that the water storage tank 20 can be easily removed from the advancing / retreating moving mechanism 40 as shown in FIG. be able to.

The user removes the lid 22 of the water storage tank 20 removed from the main body 30 and fills the water storage tank 20 with a predetermined amount of water. Subsequently, the user sets the water storage tank 20 in the advancing / retreating moving mechanism 40 by reattaching the lid 22 to the water storage tank 20 and then fitting the heater side power supply connector 12 and the power supply side power supply connector 42 in an uneven manner. ..

Next, the user pushes the advancing / retreating movement mechanism 40 into the main body 30, and sets the water storage tank 20 inside the main body 30 as shown in FIGS. 9 and 10. At this time, one link body 62 rotates while shortening to rotate the link portion 60 (rotary shaft portion 64), and the closing plate 52 attached to the other link body 63 is closed to the lid 22 of the water storage tank 20. The pumping pipe 50 and the temperature sensor 56 are brought into the inside of the water storage tank 20 through the portion of the elongated hole 24 formed in the lid 22.

When the closing plate 52 comes into contact with the lid 22, the closing plate 52 adheres to the sealing packing 26 projecting from the upper surface of the lid 22 while elastically deforming, and forms a long hole 24 which is an opening on the upper surface of the water storage tank 20. It can be closed in a sealed state. The sealing packing 26 of the present embodiment is the sealing packing 26 in which the water storage tank 20 is deformed by the extra rotation of the closing plate 52 due to the pushing operation when the water storage tank 20 is caught by the main body 30 by the push catch type catch mechanism 44. It is formed at a protruding height.

By advancing and retreating the pumping pipe 50 and the temperature sensor 56 to and from the water storage tank 20 according to the position of the advancing / retreating movement mechanism 40, the water storage tank 20 can be easily attached to and detached from the main body 30. Similarly, depending on the position of the advancing / retreating movement mechanism 40, it is possible to switch between the sealed closed state and the non-closed state of the upper surface opening of the water storage tank 20 by the closing plate 52, so that the water storage tank 20 can be switched from the water storage tank 20. Water vapor is not released inside the main body 30. This makes it possible to prevent failures of the power supply unit 80, the operation control unit, and the storage unit (none of which are shown) due to the steam of hot water produced in the water storage tank 20.

Subsequently, the user operates an extraction start switch (not shown) to start coffee extraction. When the extraction start switch is operated, the operation control unit represented by the CPU controls the operation of the power supply unit 80 based on the coffee extraction program stored in advance in the storage unit represented by the non-volatile memory. Power is appropriately supplied to the hot water supply pump 70 connected to the heater 10 and the pumping pipe 50. With such an operation control unit and a coffee extraction program, hot water at an appropriate temperature can be supplied from the hot water supply nozzle 72 to the coffee powder of the coffee extraction unit 90 at an appropriate timing and amount, so that the quality can be achieved in a short time. You can get high coffee.
