Description

  The present invention relates to a cup holder of a construction machine, and more particularly to a cup holder having a function of keeping warm and cold a cup containing a beverage.

  Conventionally, various cup holders mounted on construction machines are known. For example, there is a cup holder that is attached to the front surface of an air outlet of an air conditioner duct in an automobile interior. This cup holder serves as a lid that covers and covers the front of the air outlet when not in use, and has a structure that can be used as a tray-shaped cup cradle when opened when used (e.g., patent document) 1).

Further, as another cup holder, hot air or cold air is directly taken into the cup container from the air conditioner duct. This cup holder has a cup storage container in which a plurality of ventilation openings connected to the air conditioning duct are provided on the peripheral surface, and the hot or cold air from the air conditioner duct is guided from the ventilation opening into the cup storage container to store the cup It has a structure in which beverages in cans or cups (hereinafter collectively referred to simply as “cups”) stored in the cup storage container can be kept warm or cold by hot air or cold air flowing in the container. (For example, see Patent Document 2 and Patent Document 3).
JP-A-7-195937 (FIGS. 1 to 4). Japanese Patent Laid-Open No. 2002-2354 (FIG. 4). Japanese Unexamined Patent Publication No. 2000-142204 (FIGS. 1 to 3).

  The cup holder described in Patent Document 1 places a cup containing a beverage on a tray-shaped cup cradle, blows hot or cold air directly from the air outlet of the air conditioner on the peripheral surface of the cup, and drinks the beverage together with the cup. It is structured to keep warm or cool. For this reason, since the cup is exposed and placed on the cup cradle, it is difficult to guide sufficient hot or cold air to the entire peripheral surface of the cup, and the entire cup containing the beverage is efficiently heated or cooled. In addition, there is a problem that heating or cooling takes time.

  The cup holders described in Patent Document 2 and Patent Document 3 have a cup storage container in which a cup is stored, and guides hot air or cold air blown from a duct of an air conditioner into the cup storage container. The beverage in the cup is kept warm or cold at a desired temperature together with the cup stored in the cup storage container by the hot air or the cold air flowing inside, so that the problem of Patent Document 1 can be solved efficiently. .

  However, in the cup holders described in Patent Document 2 and Patent Document 3, hot air or cold air is always blown into the room from the air outlet regardless of whether the cup is placed. This is not efficient because the air to be blown out is dispersed and the required air volume at the air outlet is reduced.

  Furthermore, the amount of warm air or cold air guided from the vents in the cup holders described in Patent Document 1, Patent Document 2, and Patent Document 3 is always constant unless the air volume on the air conditioner side is changed. Since it is not a structure that can adjust the air volume only at the vent, it is not efficient from this point of view.

  Therefore, there is a technical problem to be solved in order to obtain a structure that can effectively use the air from the air conditioner and efficiently and reliably keep the beverage in the cup warm or cold without using a complicated structure. Therefore, an object of the present invention is to solve this problem.

Provide a holder.

  According to this configuration, when the cup storage container is rotated to the blowing position, hot air or cold air can be guided to the cup storage container from the air outlet of the air conditioner duct through the ventilation opening. On the contrary, if it rotates to the interruption | blocking position, the warm air or cold air sent into the cup storage container from the air blower outlet of an air conditioner duct can be interrupted | blocked.

  The invention according to claim 2 is to provide a cup holder for a construction machine that can stop the rotation of the cup container at an arbitrary position between the blowing position and the blocking position.

  According to this configuration, by adjusting the rotation amount of the cup container, that is, the rotation position, the coincidence amount between the air outlet and the ventilation port, that is, the opening amount through which air passes can be adjusted. By adjusting the amount of rotation of the cup storage container in this way, it is possible to freely adjust the amount of hot or cold air blown out into the cup storage container.

  A third aspect of the present invention provides a cup holder for a construction machine in which the vent hole is provided on a side surface of the cup container.

  According to this configuration, the hot air or the cold air guided into the cup storage container is directly blown against the side surface of the cup in the cup storage container, and the cup is rapidly heated or cooled together with the beverage inside. Can do.

  A fourth aspect of the present invention is to provide a cup holder for a construction machine in which the vent hole is provided on the bottom surface of the cup storage container.

  According to this configuration, the hot air or the cold air guided from the bottom surface into the cup storage container flows along the side surface from the bottom surface of the cup in the cup storage container, and heat or cold insulation is performed over substantially the entire cup. It is done efficiently.

  According to the first aspect of the present invention, the hot or cold air sent from the air outlet of the air conditioner duct into the cup storage container is simply rotated by simply rotating the cup storage container. Can be controlled. That is, when it is used, if it is rotated to the blowing position, hot air or cold air can be taken into the cup storage container, and if it is rotated to the shut-off position, the hot air or cold air blown into the cup storage container has another need. The hot air or the cold air can be effectively used with a simple switching operation so that the air can be sent to the air outlet.

  According to the second aspect of the present invention, the amount of air blown into the cup storage container can be freely adjusted by adjusting the amount of rotation of the cup storage container. Detailed heat insulation or cold insulation can be performed efficiently.

  In the invention described in claim 3, since the hot air or the cold air guided into the cup storage container is directly blown against the side surface of the cup in the cup storage container, in addition to the effects of the invention described in claim 1 or 2. The cup can be heated or cooled rapidly.

  In the invention according to claim 4, the hot air or the cold air guided from the bottom surface into the cup storage container is caused to flow along the side surface from the bottom surface of the cup in the cup storage container. In addition to the effect of the present invention, it is possible to efficiently perform heat insulation or cold insulation over substantially the entire cup.

FIG. 4 is a cross-sectional view taken along line AA in FIG. 3, FIG. 5 is an enlarged view of a portion D in FIG. 4, and FIG. 6 is a side view seen from the direction of arrow E in FIG. 3 to 6, the cup holder 23 has a cup storage container 26 attached at a position in contact with the air outlet 25 of the air conditioner duct 24. The trim cover 21 is provided with a circular attachment hole 27 in a portion where the cup storage container 26 is attached.

  The cup container 26 is made of a resin material, and has a cylindrical main body portion 26a and a bottom wall portion 26b with a closed bottom surface of the main body portion 26a, and is formed in a generally cup shape having an open upper surface. Has been. A flange 29 is provided on the outer peripheral portion of the upper surface opening 28 over the entire periphery.

  Further, a locking piece 30 is provided at a lower portion of the flange portion 29 on the side surface, that is, the peripheral surface of the main body portion 26a. One or more locking pieces 30 may be provided. As shown in detail in FIGS. 5 and 6, the locking piece 30 is formed by providing a U-shaped slit 31 on the peripheral surface of the main body portion 26 a of the cup container 26. The lower side is fixed, and the upper side is made elastically deformable inward and outward. Further, the outer surface of the locking piece 30 is formed as an inclined surface that gradually protrudes outward as it goes from the lower side to the upper side, and the upper end surface of the locking piece 30 protrudes outward from the peripheral surface of the main body 26a. It is made as a nail 30a. The distance between the locking claw 30a and the collar portion 29 is substantially equal to the thickness of the trim cover 21, and the trim cover 21 can be sandwiched between the locking claw 30a and the collar portion 29. It has a structure that can be done.

  The outer peripheral portion of the main body 26a is provided with a plurality of vent holes 32 (three in this example, 32a, 32b, and 32c) for guiding air from outside into the cup storage container 26. . The size of the air vent 32 is formed substantially equal to the air outlet 25 of the air conditioner duct 24.

  Next, the operation when the cup storage container 26 is attached to the trim cover 21 will be described. First, the cup container 26 is dropped into the mounting hole 27 with the bottom wall portion 26b facing downward. When the locking piece 30 comes into contact with the inner surface of the mounting hole 27 and stops, when the cup container 26 is pressed further downward, the inclined surface of the locking piece 30 is pressed against the inner surface of the mounting hole 27 and can be elastically deformed.

  In this way, the cup container 26 attached to the trim cover 21 can be rotated horizontally within the attachment hole 27 when the finger is placed on the collar 29 to turn. In addition, the air outlet 25 of the air conditioner duct 24 is always provided at a position that coincides with the air vent 32 once while the cup storage container 26 rotates once. And when putting the cup 33 in which the drink was put, the cup 33 is accommodated in the cup storage container 26. Thus, the bottom surface of the cup 33 is received by the bottom wall portion 26b, and the side surface is received and held by the inner surface of the main body portion 26a. FIG. 4 shows a state in which the cup 33 is disposed in the cup storage container 26.

  7A and 7B are diagrams for explaining the operation of the cup holder 23. FIG. 7A shows a state in which the cup container 26 is rotated to the air blowing position where the air outlet 32 is aligned with the air outlet 25, and FIG. The state which rotated the cup storage container 26 to the shielding position where walls other than the vent hole 32 corresponded to the exit 25 is shown.

  When the cup holder 23 configured in this manner is not used, the cup storage container 26 is rotated to a shielding position where the wall other than the ventilation port 32 is aligned with the air outlet 25 as shown in FIG. 7B. The air outlet 25 is kept closed by the peripheral wall of the main body 26a. 3 and 4 also show a state in which the cup storage container 26 is arranged at the shielding position. Thus, when the cup holder 23 is not used, if the air outlet 25 of the air conditioner duct 24 in the air conditioner 18 is shut off and closed by the peripheral wall of the main body portion 26a of the cup storage container 26, the air outlet 25 The air blown out from the air is sent to an air outlet that requires other warm air or cold air, and is efficiently blown out from the other air outlet.

  On the other hand, as shown in FIG. 7A, when the cup container 26 is rotated to the air blowing position where the air outlet 32 is aligned with the air outlet 25, the temperature from the air conditioner duct 24 of the air conditioner 18 is increased. Wind or cold air is guided from the air outlet 25 through the ventilation opening 32 into the cup storage container 26 and blown directly against the side surface of the cup 33 in the cup storage container 26. Further, after circling in the cup storage container 26, it is discharged to the outside of the cup storage container 26 from the upper surface opening 28, and the beverage can be rapidly heated or cooled together with the cup 33 by this air flow.

  The amount of warm air or cold air guided from the air outlet 25 through the ventilation opening 32 into the cup container 26 is the same as that of the air outlet 25 except for adjusting the air volume of the air conditioner 18. It is possible to freely adjust the amount to be adjusted, that is, the amount of rotation of the cup container 26, and finer heat insulation or cold insulation can be efficiently performed.

  In this structure, a plurality of ventilation holes 32 for guiding air from outside into the cup storage container 26 are provided in the bottom wall portion 26b of the cup storage container 26 that is mounted in the mounting hole 27 of the trim cover 21 so as to be horizontally rotatable. (In this example, it is divided into three, 32a, 32b, and 32c). The size of the ventilation port 32 is substantially equal to the air outlet 25 of the air conditioner duct 24. The air outlet 25 of the air conditioner duct 24 is provided at a position in contact with the bottom wall portion 26b of the cup storage container 26, and the air vent 32 is always provided once during the rotation of the cup storage container 26. It is provided at a position that matches. When the cup 33 containing the beverage is placed, when the cup 33 is stored in the cup storage container 26, the bottom surface of the cup 33 is received by the bottom wall portion 26b and the side surface is received by the inner surface of the main body portion 26a. Held. FIG. 9 shows a state in which the cup 33 is arranged in the cup storage container 26 in this way.

  10A and 10B are diagrams for explaining the operation of the cup holder 23. FIG. 10A shows a state in which the cup storage container 26 is rotated to a blowing position where the air outlet 32 is aligned with the air outlet 25, and FIG. The state which rotated the cup storage container 26 to the shielding position which made the wall other than the ventilation port 32 correspond to the blower outlet 25 is shown.

  When the cup holder 23 configured as described above is not used, the cup container 26 is rotated to a shielding position in which the wall other than the air vent 32 coincides with the air outlet 25 as shown in FIG. Leave it in the state. 8 and 9 also show a state in which the cup storage container 26 is disposed at the shielding position. Thus, when the cup holder 23 is not used, if the air outlet 25 of the air conditioner duct 24 of the air conditioner 18 is closed and closed by the bottom wall portion 26b of the main body portion 26a, the air outlet 25 is blown out. The warm air or the cold air is turned to an air outlet that requires other hot air or cold air, and is efficiently blown out from the other air outlet.

  On the other hand, as shown in FIG. 10A, when the cup container 26 is rotated to the air blowing position where the air outlet 32 is aligned with the air outlet 25, the temperature from the air conditioner duct 24 of the air conditioner 18 is increased. Wind or cold air is guided from the air outlet 25 through the ventilation opening 32 into the cup storage container 26, blown toward the bottom surface of the cup 33 in the cup storage container 26, and then along the side surface from the bottom surface. Then, the liquid flows along the outer surface of the cup 33 and is then discharged from the upper surface opening 28. With this air flow, the beverage can be heated or cooled together with the cup 33.

  In addition, the amount of hot or cold air guided from the air outlet 25 through the ventilation opening 32 into the cup storage container 26 is the same as that of the air outlet 25 except for adjusting the air volume of the air conditioner 18. It is possible to freely adjust the amount to be adjusted, that is, the amount of rotation of the cup container 26, and finer heat insulation or cold insulation can be efficiently performed.
