Description

  The present invention relates to a beverage extractor such as a home coffee maker.

  The beverage extractor stores beverage extraction ingredients such as coffee powder directly in the basket or in a filter, puts a container for receiving the extract on a hot plate located below the basket, and turns on the switch. The raw water supplied from the water tank becomes hot water while flowing along the electric heater, rises up the pumping pipe, reaches the upper part of the basket, and is ejected from the discharge port to the basket. Charging parts such as an electric heater and a switch, and a pipe line from the water tank to the discharge port are built in the casing. The water tank is provided integrally with the casing or separately. The casing is provided so as to rise between the hot plate and the water tank and protrude above the hot plate. The discharge port is disposed on the lower surface of the upper portion of the hot plate of the casing. Conventionally, a basket is provided so as to be openable and closable around a vertical axis with respect to a casing. When the basket is opened, the storage space of the basket is detached from the lower part of the upper part of the hot plate of the casing, and the beverage extraction raw material can be stored. When the basket is closed, the basket closes with the rising part of the casing and the upper part of the hot plate. In this state, the hot water ejected from the discharge port is supplied to the beverage extraction raw material in the basket, and when the hot water passes through the beverage extraction raw material, it is extracted as a beverage and flows down and stored in the container. The basket also has the effect of reducing the external leakage of steam and making it difficult to cool the extract (for example, see Patent Document 1).

  The basket of the above-mentioned patent document 1 is provided so that attachment or detachment with respect to a casing is possible in order to enable round washing. Specifically, the upper and lower protrusions serving as the upper and lower shafts are provided on the basket by integral injection molding. Moreover, the upper and lower fitting parts for inserting and removing the upper and lower protruding ends are provided in the casing by integral injection molding. Only when the basket is in the fully open position, the basket can be lifted upward, and by this lifting, the lower projecting end portion is removed from the lower fitting portion, and the lower side of the basket is shifted in the horizontal direction. After removing the lower protruding end from above, the basket can be lowered and the upper protruding end can be removed from the upper fitting portion. When attaching the basket to the casing, the basket is set to the fully open position, and the upper side of the basket is tilted toward the casing, and the upper protruding end is inserted into the upper fitting part, and the basket is straightened. The lower projecting end portion is inserted into the lower fitting portion.

JP 2007-301293 A

  However, the beverage extractor disclosed in the above-mentioned Patent Document 1 needs to be lifted or tilted while keeping the basket in the fully open position when the basket is attached to or detached from the casing. There is room for improvement in difficult points.

  In view of the above circumstances, it is an object of the present invention to easily attach and detach a basket that can be opened and closed around a vertical axis with respect to a casing.

  In order to solve the above problems, the present invention comprises a casing that rises between a hot plate and a water tank and protrudes above the hot plate, and a basket that can be opened and closed about a vertical axis with respect to the casing. In the beverage extractor provided with the upper and lower protruding ends that serve as the upper and lower shafts, and provided with the upper and lower fitting portions for inserting and removing the upper and lower protruding ends on the casing, at least one of the upper and lower protruding ends is supported. A manual operation mechanism is provided that can be moved up and down with respect to the fitting portion to be moved and moves the at least one protruding end portion until the fitting portion comes out of the corresponding fitting portion.

According to the configuration of the present invention, when the manual operation mechanism is operated, at least one of the upper and lower protrusions can be moved until it comes out of the corresponding fitting portion. Accordingly, the basket that can be opened and closed around the vertical axis can be easily attached to and detached from the casing.
The basket is removed because it is washed as described above. If a manual operation mechanism is adopted, the basket is not provided with an electric part and can be washed. If a manual operation mechanism is provided in the basket, an operation hole for moving the operation member from the outside does not need to be provided in the casing. If this operation hole is formed in the casing, there is a risk that overflow water or dew condensation water at the time of water replenishment may reach the built-in charging part from the operation hole along the outer surface of the casing, and it is forced to provide a separate seal structure. If a manual operation mechanism without a charging part is provided in the basket, it is not necessary to add a seal structure, and there is no problem with round washing.

Each embodiment of the present invention will be described below.
The beverage extractor according to the first embodiment (hereinafter simply referred to as “first embodiment”. The same is also abbreviated in other embodiments) fixes the lower protruding end to the basket, and the upper protruding end. This is a mechanism in which the part is provided so as to be movable up and down.

It is preferable that only one of the upper and lower protrusions is moved by the manual operation mechanism. When both the upper and lower protruding ends are moved, both protruding ends are removed at the same time, so that the basket can be easily attached and detached. However, since it becomes easy to remove the basket at a stretch, if the user does not remove the basket while holding the basket securely, the basket may be dropped unexpectedly. Further, the operation member becomes heavy and the mechanism becomes complicated.
When only one protruding end is moved, the other protruding end is fixed and cannot be removed at once when the basket is removed. Further, the operation of the operation member is light and the mechanism can be simplified. When the basket is attached, it is performed in a state where the other protruding end portion is put in the other fitting portion first.
Here, considering the visibility of the upper and lower fitting parts when attaching the basket, the upper fitting part needs to be viewed from below with a lower viewpoint than the upper fitting part. The joint can be looked down from above.
Therefore, according to the first embodiment, when the basket is removed, the lower projecting end portion is first inserted into the lower fitting portion having excellent visibility when the basket is attached, and the upper projecting end portion is fitted over the upper projecting end portion as a fulcrum. It can be aligned with the joint, and it is relatively easy to perform the installation work.

  The basket is kept in a closed state unless it is subjected to an opening operation. Further, the weight of the basket is supported by the casing from below in a state where the upper and lower protruding end portions are fitted in the upper and lower fitting portions. Even if the manual operation mechanism is activated during beverage extraction, the basket does not always fall from the casing because of the engagement and the casing support, but for safety, the manual operation mechanism during beverage extraction It is preferable to reliably prevent operation.

  Therefore, in the second embodiment, when the operation member of the manual operation mechanism moves in a state where the basket is closed, at least one of the upper and lower projecting ends is removed from the corresponding fitting portion before the operation member. Butt against the casing, and the butt does not occur when the basket has a specific opening or more.

Even if the operating member moves with the basket fully closed, there is no fear that the upper and lower protrusions will come off against the casing.
Further, when the basket is more than a specific opening degree, the abutment does not occur. For this reason, when removing a basket before and after beverage extraction, the operation member can be moved with the basket at a specific opening or higher. At this time, the basket only needs to have a specific opening or more, and it is not necessary to maintain the opening at the full opening position as in the prior art.
It is necessary to move the operation member while maintaining the basket at a specific opening or more, and it is difficult to hold the basket and operate the operation member simultaneously with one hand. For this reason, the second embodiment can naturally guide the user to hold the basket with one hand and move the operation member with the other hand. This is advantageous in preventing the basket from being dropped. The one-handed operation as described above is not preferable because it is easy to accidentally remove the basket.

  The safety structure as in the second embodiment may be omitted, or the operation member may be lost due to an unforeseen cause, and the use may be continued while the end is not sweet.

Therefore, in the third embodiment, the operation member of the manual operation mechanism is provided so as to push backward from the front surface of the basket.
Here, the front surface of the basket refers to a surface portion that can be seen when facing the front side with the basket closed. The rear means a direction in which a force for closing the basket is generated when the operation member is pushed with the basket opened.

In the third embodiment, when the basket is in a closed state, even if at least one of the protruding ends is removed, the basket that has received the operating force is unlikely to move to the left and right, and the basket is not easily supported by the casing.
Even if the user pushes the operating member without holding the basket with the basket opened, the operating force acts from the front of the basket toward the rear, so that the basket is closed around the vertical axis. It becomes power. Therefore, the operation force is released by the closing movement of the basket, the operation member cannot be pushed, and the basket is merely closed. For this reason, the above-mentioned one-handed operation can be prevented.
As described above, the third embodiment can prevent an unexpected basket drop at the time of beverage extraction only by setting the operation member and setting the operation direction.

  Further, when the basket is held with one hand, it is held from both the left and right sides of the basket. At this time, since the pushing operation of the operation member is in the direction along the front-rear direction, the gripping direction and the operation direction intersect. For this reason, in the third embodiment, it is difficult to perform the one-handed operation described above, and it is possible to guide to a two-handed operation.

  The above-described movement of the basket to the left and right sides can be prevented by using the casing.

That is, in the fourth embodiment, the basket and the casing are provided with a contact portion for restricting the lateral displacement of the basket with respect to the left and right sides with respect to the casing when the basket is closed. The above-mentioned restricted state is achieved by movement.
Here, the regulation means that the basket support by the casing does not come off due to the shift to the left and right sides, and it is not always necessary for the contact portion to contact in the closed state.

In a state where the basket is fully closed, the positional displacement of the basket to the left and right sides with respect to the casing is restricted by the contact between the casing side and the contact portion on the basket side. Since the basket is brought into a restricted state by the closing movement, it is reliably prevented from shifting to the left and right sides during beverage extraction. Since the regulation can be removed by opening the basket, there is no problem in removing the basket.
As described above, the fourth embodiment can prevent the basket from dropping unexpectedly during beverage extraction only by providing a contact portion between the casing and the basket.

  In the fourth embodiment, since the opening and closing movement of the casing and the basket is used, a safety structure can be provided regardless of the operation direction of the operation member.

  Therefore, the fifth embodiment is provided in the fourth embodiment so as to push the operation member of the manual operation mechanism from the left and right side surfaces toward the left and right sides.

In this type of beverage extractor, after the switch is turned on, the first water discharged is the water remaining in the pumping pipe, and it takes time until hot water is discharged. When extracting coffee, the extraction temperature greatly affects the flavor. For this reason, the user who sticks to the taste keeps the basket open for a while, closes the basket after hot water comes out, and puts a container for storing the extracted beverage on the hot plate. At this time, the user having the container for the extracted beverage may stand in front of the beverage extractor and insert it downward from the front of the basket after closing the basket.
Therefore, it is more difficult to accidentally hit the operation member when placing the container for the extracted beverage from the front when the operation member of the manual operation mechanism is pushed from the left and right sides toward the other side. There is an advantage that it is difficult to move.
5th Embodiment can also prevent the above-mentioned basket fall, making it difficult to produce the erroneous contact of the said container.

Hereinafter, a beverage extractor according to a first embodiment of the present invention will be described with reference to the accompanying drawings (hereinafter, simply referred to as “first embodiment”, and similarly in other embodiments).
As shown in FIGS. 1 to 4, in the first embodiment, a dedicated container 1 for receiving an extract is stored in a basket 10 in a state where a beverage extraction material such as coffee powder is placed in a filter (not shown). It is placed on the hot plate 2 located below the basket 10. When a switch (not shown) is turned on, the raw water supplied from the water tank 3 becomes hot water while flowing along the electric heater 4, rises up the pumping pipe 5, reaches the upper side of the basket 10, and is discharged from the discharge port 6. It is ejected and supplied into the basket 10.

  The charging section such as the electric heater 4 and the switch, and the pipe line from the water tank 3 to the discharge port 6 are built in the casing 20. The water tank 3 is provided separately from the casing 20. The casing 20 is provided so as to rise between the hot plate 2 and the water tank 3 and protrude above the hot plate 2. The discharge port 6 includes a water purification filter and is disposed on the lower surface of the upper portion of the hot plate of the casing 20. The rising portion 21 of the casing 20 supports the water tank 3.

  The basket 10 is provided so as to be openable and closable around the vertical axis with respect to the casing 20. The basket 10 includes a cup 11 that houses a filter and a holder 12 that holds the cup 11. In addition, the cup 11 and the holder 12 can also be provided integrally.

  The holder 12 is provided with protruding end portions 13 and 14 serving as the vertical axis. The casing 20 is provided with upper and lower fitting portions 22 and 23 through which the upper and lower protruding end portions 13 and 14 are inserted and removed.

  2, 3, and 5, the holder 12 of the basket 10 is formed on the rising portion 21 of the casing 20 with the upper and lower projecting ends 13 and 14 fitted in the upper and lower fitting portions 22 and 23. The support surface 24 is supported from below. When the basket 10 is fully closed, the support surfaces 24 and 25 of the rising portion 21 are supported from below on the left and right sides of the basket 10.

  When the basket 10 is closed, as shown in FIGS. 1, 2, and 6, the engagement protrusion 15 provided on the holder 12 is elastically deformed and is forced into the engagement recess 26 of the casing 20 to be elastic. The basket 10 is maintained in the closed state by the hooking of the recovered engaging protrusion 15. In this state, the holder 12 is closed with the rising portion 21 of the casing 20 and the upper portion of the hot plate.

  When the basket 10 is opened using the knob 16 that is the rotation tip of the basket 10, the engagement protrusion 15 is removed from the engagement recess 26 due to elastic deformation. By opening the basket 10, the cup storage space of the holder 12 is removed from the lower side of the casing 20, and the filter containing the beverage extraction raw material can be stored.

  As shown in FIGS. 2 and 7, the lower projecting end portion 14 is fixed to the basket 10 by being integrally formed with the holder 12. The upper projecting end portion 13 is provided so as to be movable up and down with respect to the upper fitting portion 22.

  As shown in FIGS. 1, 3, and 7, the basket 10 is provided with a manual operation mechanism that moves the upper projecting end portion 13 until it comes out of the upper fitting portion 22. The manual operation mechanism includes an operation member 31 exposed from an operation hole vacated on the front surface of the basket 10 and a motion conversion unit that lowers the push operation of the operation member 31 until the upper projecting end portion 13 comes out of the upper fitting portion 22. .

  The operation member 31 is provided so as to be able to reciprocate backward from the front surface of the basket 10. The motion converting unit includes a tapered surface 31a provided on the operation member 31, a tapered surface 13a provided on the upper protruding end 13, a spring 32 for returning the operating member 31 to the standby position, and the upper protruding end 13 at the standby position. And a spring 33 for returning to.

  As shown in FIG. 7B, when the operation member 31 is pushed rearward against the spring 32 from the front surface of the holder 12, the taper surface 31 a of the operation member 31 and the taper surface 13 a of the upper projecting end 13 are formed. By sliding contact, the upper projecting end portion 13 is lowered against the spring 33 and can be removed from the upper fitting portion 22. When the pushing operation of the operation member 31 is stopped, the operation member 31 and the upper projecting end portion 13 are returned to the standby position by the elastic repulsion force accumulated in the springs 32 and 33.

  As shown in FIG. 7A, when the operation member 31 and the upper protruding end portion 13 are in the standby position, the upper protruding end portion 13 can be fitted into the upper fitting portion 22. When the operating member 31 and the upper projecting end portion 13 are in the standby position, if the upper projecting end portion 13 is pushed downward against the spring 33, the operating member 31 does not move in the front-rear direction, and only the upper projecting end portion 13 is moved. Descends. When the upper projecting end portion 13 is no longer pushed, the upper projecting end portion 13 is returned to the standby position by the elastic repulsive force of the spring 33.

  As shown in FIGS. 2 and 7, the above-described manual operation mechanism is assembled from the rear into a space formed between the outer wall of the holder 12 and the inner wall of the cup housing portion, and the space is closed by the lid member 34 from the rear. It has become. The lid member 34 has a through hole for projecting the operation member 31 rearward. In the state where the basket 10 is fully closed, the rear end protruding portion 31b of the operation member 31 faces the abutting surface 27 integrally formed with the rising portion 21, as is apparent from FIGS. 5 and 7A. Yes. When the operating member 31 is pushed rearward in this state, the rear end protruding portion 31b of the operating member 31 faces rearward with respect to the abutting surface 27 before the upper protruding end portion 13 comes out of the upper fitting portion 22. At the end, the manual operation mechanism does not work. As shown in FIG. 8, when the basket 10 has a certain opening degree or more, the rearward extension line of the rear end protrusion 31 b of the operation member 31 does not intersect with the abutment surface 27, and the abutment does not occur. Therefore, as long as the basket 10 is maintained at a specific opening or more, as shown in FIG. 7B, the manual operation mechanism can be operated by pushing the operation member 31 backward.

  Since the upper projecting end portion 13 is lowered by the pressing operation of the operation member 31 and comes out of the upper fitting portion 22, the basket 10 is lifted when the opening is equal to or larger than that shown in FIG. It becomes easy. For this reason, in the first embodiment, it is easy to remove the basket 10 by removing the lower projecting end portion 14 from the lower fitting portion 23 shown in FIG. The basket 10 does not have a built-in electric part and can be washed. Since the basket 10 is provided with a manual operation mechanism, there is no particular seal, and there is no hole for exposing the operation member 31 in the casing 20 containing the charging unit such as the electric heater 4.

  When attaching the basket 10, the upper side of the holder 12 is tilted to the right side, the lower projecting end portion 14 is put into the lower fitting portion 23, and the upper projecting end portion 13 at the standby position is set by the spring 33 as a fulcrum. It can be adjusted to 22 positions. At this time, since the upper protruding end 13 can be lowered, it is difficult to be caught on the casing 20 side. For this reason, in the first embodiment, the basket 10 can be easily attached.

  The upper protruding end 13 when the basket is attached can be lowered using the casing 20 as well as being lowered by the operation of the manual operation mechanism. In the first embodiment, as shown in FIGS. 2 and 7A, the upper surface of the upper protruding end 13 is rubbed against the tapered surface 28 while the holder 12 is tilted while being brought into contact with the tapered surface 28 of the casing 20. Thus, the upper projecting end portion 13 can be put into the upper fitting portion 22 while being lowered against the spring 33. In the first embodiment, it is not necessary to perform alignment while pushing the operating member 31, and alignment can be easily performed by guiding the tapered surface 28.

  In the first embodiment, the lower projecting end portion 14 is first put in the lower fitting portion 23 having excellent visibility, and the upper projecting end portion 13 can be aligned with the upper fitting portion 22 using the lower projecting end portion 14 as a fulcrum. It is relatively easy to perform installation work.

  Further, in the first embodiment, even if the operation member 31 moves with the basket 10 closed, the rear end protrusion 31b of the operation member 31 abuts against the abutting surface 27 of the casing 20, so , 14 is not worried. If the basket 10 is set to a specific opening or more, the abutment does not occur and the operation member 31 can be moved. At this time, it is not necessary to keep the basket 10 in the fully open position. It is necessary to move the operation member 31 while maintaining the basket 10 at a specific opening or higher, and it is difficult to simultaneously grasp the basket 10 and operate the operation member 31 with one hand. For this reason, the first embodiment can naturally guide the user to hold the basket 10 with one hand and move the operation member 31 with the other hand.

  As shown in FIG. 5, when the basket 10 is in a closed state, the front-rear direction, which is the operation direction of the operation member 31, coincides with the front-rear direction on the casing side. For this reason, the rear end protruding portion 31b of the operation member 31 is used without being broken, the operation member 31 is pushed rearward with the basket 10 closed, and the upper protruding end portion 13 comes out of the upper fitting portion 22. Even so, the basket 10 receiving the operating force is difficult to move to the left and right sides, and the support of the basket by the support surfaces 24 and 25 of the rising portion 21 is difficult to come off. For this reason, the first embodiment can prevent an unexpected basket drop at the time of beverage extraction only by the arrangement of the operation member 31 and the setting of the operation direction.

  Further, the gripping direction of the basket 10 (gripping from the left and right sides) and the operation direction of the operation member 31 (direction along the front-rear direction) are set to intersect with each other. For this reason, in the first embodiment, it is difficult to perform the one-handed operation described above, and it can be guided to a two-handed operation.

  The configuration that enables raising and lowering at least one of the upper and lower protrusions and the configuration of the manual operation mechanism can be changed to other mechanisms. A modification example will be described below. Only the differences from the first embodiment will be described below.

  As shown in FIGS. 9 and 10, the second embodiment is a manual operation mechanism that moves both the upper projecting end portion 41 and the lower projecting end portion 42 until they are removed from the corresponding fitting portions 22 and 23. The operation member 43 of the manual operation mechanism is provided so as to be pushed from the left and right side surfaces of the holder 12 toward the left and right sides as shown in FIG. The operation member 43 is guided in the left-right direction by the lid member 45.

  As shown in FIGS. 9 and 10, projecting shafts 41a and 42a are provided on the upper and lower projecting ends 41 and 42, respectively. The operation member 43 is provided with tapered surfaces 43a and 43b corresponding to the projecting shafts 41a and 42a. When the operating member 43 is pushed against the spring 44 from the state shown in FIGS. 10A and 10B, the protruding shaft 41a is in sliding contact with the tapered surface 43a as shown in FIG. 41 is lowered until it comes out of the upper fitting portion 22. At the same time, the projecting shaft 42 a is brought into sliding contact with the tapered surface 43 b, so that the lower projecting end portion 42 is raised until it comes out of the lower fitting portion 23. When the pushing operation of the operating member 43 is stopped, the upper and lower projecting ends 41 and 42 are returned to the standby positions shown in FIGS. 10A and 10B by the elastic recovery force of the spring 44. As described above, in the second embodiment, the upper and lower protruding end portions 41 and 42 can be removed from the corresponding fitting portions 22 and 23. The second embodiment is suitable when priority is given to preventing the upper and lower protrusions 41 and 42 from being caught when attaching and detaching the basket, rather than reducing the operational feeling of the operation member 43.

  As shown in FIG. 11, a contact portion 46 a that protrudes so as not to interfere with the holder 12 that opens and closes is provided on the rising portion 21 of the casing. On the other hand, the basket holder 12 is provided with a contact portion 46b in a box shape with an open rear end. The contact portion 46a on the rising portion 21 side is inserted into and removed from the contact portion 46b on the holder 12 side by opening and closing the basket. Although a concave contact portion can be provided on the casing side and a contact portion protruding rearward can be provided on the basket side, it is not preferable to provide a protrusion at the rear end of the swiveling basket.

  With the basket fully closed, the contact portions 46a and 46b regulate the displacement of the basket to the left and right sides with respect to the casing (see FIG. 11D). This restriction is performed so that the basket is not supported by the support surface of the rising portion 21 even if at least one of the upper and lower projecting ends 41 and 42 is removed. Clearance is set to avoid interference when the basket is opened and closed, and the contact portions 46a and 46b are not always in contact with each other in the closed state.

  In the second embodiment, the contact portions 46a and 46b are restricted by the closing movement of the basket, so that the basket is reliably prevented from shifting to the left and right sides during beverage extraction. For this reason, the second embodiment can prevent the basket from being unexpectedly dropped during the beverage extraction only by providing the abutting portions 46a and 46b on the rising portion 21 of the casing and the holder 12 of the basket.

  As shown in FIGS. 10A and 11A, the rib 47 protruding from the rising portion 21 of the casing restricts the movement of the operation member 43 to the left and right other side with the basket closed. When the basket is at a certain angle or more, the regulation of the rib 47 is removed. As in the second embodiment, the structure in which the restriction of the operation member is released when the basket is opened has an advantage that the above-described one-hand operation can be easily prevented. In the second embodiment, since the upper and lower protrusions 41 and 42 can be raised and lowered, the rib 47 can be omitted, and the basket can be removed and removed forward without opening.

  Further, the second embodiment pushes the operation member 43 of the manual operation mechanism from the left and right side surfaces toward the left and right sides, so that an error occurs when placing the extracted beverage container 1 shown in FIG. 1 on the hot plate 2 from the front. Thus, it is difficult to hit the operation member 43 shown in FIG. 11A, and at this time, the operation member 43 is difficult to move.

  Further, the operation member 43 is exposed from the wall surface portion having the maximum width on both the left and right sides of the holder 12. In other words, the operation member 43 is arranged in a width portion where the finger is hardly caught when the holder 12 is gripped. For this reason, in the second embodiment, it is difficult to perform the above-described one-hand operation, and it is possible to guide to the above-described two-hand operation.

  As shown in FIGS. 12 and 13, the third embodiment is a manual operation mechanism in which the upper projecting end portion 51 can be moved up and down and the operation member 52 is integrally formed with the upper projecting end portion 51. The upper projecting end portion 51 is prevented from being detached from the holder 12 by a retaining member 53. When the operation member 52 is pushed down against the spring 54, the upper projecting end portion 51 can be removed from the upper fitting portion 22. When the push-down of the operation member 52 is stopped, the upper protruding end 51 is returned to the standby position by the elastic recovery force of the spring 54.

  As shown in FIGS. 13A and 13C, the rib 55 protruding from the rising portion 21 of the casing restricts the lowering of the operation member 52 in a state where the basket is closed. At this time, the rib 55 and the protruding portion 52a of the operation member 52 are in a position completely deviated from the vertical axis of the basket, and the restriction of the rib 55 is released when the basket is at a specific angle or more.

  The third embodiment has an advantage that the one-hand operation described above cannot be performed because the operation direction of the operation member 52 is the vertical direction. In the third embodiment, since the upper projecting end portion 51 and the operation member 52 are integrally formed, the number of parts can be reduced.
