Description

  The present invention relates to a fan that can be disassembled and assembled.

  The electric fan basically includes a support extending from a base, an electric motor case installed on the support, and a fan guard. When such a fan is used and stored in the outer box, the supporting column connecting the pedestal and the fan guard is long, resulting in a useless space between the fan guard and the pedestal, and the stored outer box. The size of the container becomes large and efficient transportation becomes difficult.

  Also, when the usage frequency is low, such as in winter, the electric fan is stored in the storage, etc., but a wasteful space is created during storage as in the case of transportation, and limited storage space such as storage is effective. Inconvenience that it is not possible to use it for the purpose of placing other storage items.

Under such circumstances, various ideas for reducing useless space have been proposed.
For example, Patent Document 1 discloses a fan in which a fan guard and a fan are disassembled from a main body, the main body is bent in a motor portion from a neck portion, and a telescopic support is contracted, and is packed in an outer box using a buffer. Is disclosed.

  According to this, by bending and storing the fan head from the neck portion and reducing the height at the time of storage, the height of the exterior box can be reduced and transportation is facilitated.

JP-A-6-31767

However, when the electric fan is stored using the outer box, the outer box needs to be stored, and when using the fan, a space for storing the empty outer box is required. Moreover, even if the motor part of the electric fan is bent and the support is shortened, the length of the support can be reduced to only half due to the structure. Therefore, there is a limit to making the storage size compact, so if you try to store it with the outer box standing upright, you need to use a storage space with enough space in the height direction, and try to store it with the outer box laid down Then, a wide space is required.

  Preferred embodiments of the present invention will be described below with reference to the drawings. This embodiment is an example, and the present invention is not limited to this.

  Hereinafter, an electric fan according to an embodiment of the present invention will be described with reference to the drawings. First, the overall configuration of the electric fan will be described with reference to FIGS. 1, 2, and 3. FIG. 1 is an overall perspective view of a state in which an electric fan according to an embodiment of the present invention is assembled, FIG. 2 is an overall rear view of the electric fan according to the embodiment as viewed from the back, and FIG. It is a partial expansion perspective view which shows the head of an electric fan.

  FIG. 1 shows a fan 100 in a state of being assembled using all parts (first use state). The fan 100 includes a pedestal 10, a first column 12, a second column 14, and a front fan guard. 16, a rear fan guard 18, and an electric motor case 20. The first support column 12 is connected to the support column 10 b of the pedestal 10, and is further connected to the electric motor case 20 via the second support column 14.

As shown in FIG. 2, a first button 10 a, a second button 12 a, and a third button 14 a are provided on the back surface of the electric fan 100, and the first button 10 b provided on the pedestal 10 b of the base 10 is provided. The button 10a is for releasing the connection between the column 10b of the base 10 and the first column 12, and the second button 12a is for releasing the connection between the first column 12 and the second column 14. The third button 14a is for releasing the connection between the second support column 14 and the case connecting portion 20b. FIG. 2 shows an example in which the first button 10a, the second button 12a, and the third button 14a are provided on the rear side of the electric fan 100. However, these buttons may be provided on the front surface or the side surface. .

  As shown in FIG. 3, a storage portion 20c of a connector cover 24 is formed on the rear side of the motor case 20, and the connector cover 24 is detachably attached to the storage portion 20c. And since the storage part 20c is connected with the support | pillar part 10b of the base 10, when disassembling and storing each part of the electric fan 100 so that it may mention later, unlike the case connection part 20b, it is an electric motor. There is no need to connect. By adopting such a configuration, even if the operation panel 10c is erroneously operated when the electric fan 100 is stored, the fan is prevented from rotating.

  A pedestal 10 b to which the first support 12 is connected is erected on the pedestal 10, and a fan 50 (FIG. 15) that constitutes the head of the electric fan 100 through the first support 12 and the second support 14. The front fan guard 16, the rear fan guard 18, and the motor case 20 are supported. The pedestal 10 is provided with an operation panel 10c for controlling the power supply of the electric fan 100, the air volume adjustment, and the swinging motion.

  The pedestal 10 is formed in a circular shape, but is not limited thereto, and may be polygonal, rectangular, or any shape as long as the stability for maintaining the standing posture of the electric fan 100 can be secured.

  The 1st support | pillar 12 and the 2nd support | pillar 14 are the support | pillars comprised so that division | segmentation was possible. The length of the first support column 12 is configured to be different from that of the second support column 14. As shown in FIG. 8, small-diameter connecting rod portions 12b and 14b (connectors) are formed at one end portion of each support column 12 and 14, and the other end portion is a tube into which the connecting rod portions 12b and 14b can be inserted. Has become a department. Further, in this embodiment, a small-diameter connecting rod portion (not shown) is formed on the column portion 10b of the pedestal 10, and the motor case 20 is provided with a case connection portion 20b (FIG. 8). Fourteen connecting rod portions 12b and 14b can be inserted. In addition, each support | pillar 12,14, the base support | pillar part 10, and the case connection part 20b are provided with the electrode etc. so that it may mention later, and it supplies with electricity when it mutually connects.

Thereby, the column part 10b, the columns 12, 14 and the case connection unit 20b of the base 10 can be connected to each other in a detachable manner, and the order of connecting the columns 12, 14 may be changed. It is possible to connect even if only the support is used. Therefore, if the lengths of the two columns are different, the height can be adjusted depending on the column used. For example, as shown in FIG. 4, the first support column 12 having a long length is connected to the support column portion 10 b of the base 10, and the height of the electric fan 100 is compared with the case where both the support columns 12 and 14 are used. It can be set low. Moreover, as shown in FIG. 5, the 2nd support | pillar 14 with short length is connected with the support | pillar part 10b of the base 10, and the height of the electric fan 100 can be set still lower.

And as shown in FIG. 6, when the support | pillar part 10b of the base 10 and the case connection part 20b are directly connected, without using the 1st, 2nd support | pillars 12 and 14, the height of the electric fan 100 shall be made the lowest. You can also. In this case, if the head part of the electric fan 100 is turned upward, the electric fan 100 can blow cool air drifting near the floor to the upper part of the room and stir the air in the entire room. In particular, when performing an operation of cooling the entire room using an air conditioner (not shown) in the summer, it is suitable for an operation of stirring the air in the room to uniformly cool the entire air.

  In addition, the connection means for enabling the column 10b, the columns 12, 14 and the case connection 20b of the base 10 to be detachably connected to each other is limited to the fitting type configuration as in the above-described embodiment. For example, a screw type, a sleeve joint type, or the like may be adopted.

  Next, the 1st support | pillar and 2nd support | pillar used for the electric fan which concerns on 1st Embodiment are demonstrated in detail using FIG.10 and FIG.11. FIG. 10 is an enlarged perspective view showing the configuration of the first support column, and FIG. 11 is an enlarged perspective view showing the configuration of the second support column.

  As shown in FIG. 10, the 1st support | pillar 12 is comprised by the cylindrical cylinder 29 shape | molded by resin, The one end becomes the small diameter connection rod part 12b, and the surrounding surface of the connection rod part 12b A plurality of convex portions 12 c are formed in the axial direction of the cylindrical body 29. Furthermore, a lock mechanism 31a and a second button 12a for operating the lock mechanism 31a are provided at one end of the cylindrical body 29, and a connector portion (not shown) is provided at the end surface of the connecting rod portion 12b. Yes. The partition plate 35 is fixed at a position where the other end of the cylindrical body 29 enters from the end, and the engagement pins 33 a and 33 b are fixed at predetermined positions of the partition plate 35. Furthermore, electrodes 34 a, 34 b, 34 c are provided at predetermined positions of the partition plate 35, and a lock mechanism 31 b is configured at the peripheral edge of the partition plate 35. And the electrode of a connector part and electrode 34a, 34b are connected by the wiring in a support | pillar. Reference numeral 34c denotes an electrode that is not used in this example.

The pin outer diameters of the engaging pins 33a and 33b are slightly different. Further, these two are unevenly distributed on one semicircular side with respect to a straight line passing through the center C1 of the partition plate 35 of the support column 12.

As shown in FIG. 11, the 2nd support | pillar 14 is comprised similarly to the 1st support | pillar 12, and structures other than the length of a support | pillar are the same. That is, the second support column 14 is configured by a cylindrical tube body 30 formed of resin, and one end thereof is a small-diameter connecting rod portion 14b, and a plurality of protrusions are formed on the peripheral surface of the connecting rod portion 14b. The portion 14 c is formed in the axial direction of the cylindrical body 30. Furthermore, a lock mechanism 38 and a third button 14a for operating the lock mechanism 38 are provided at one end of the cylindrical body 30, and a connector portion 36 is provided at the end surface of the connecting rod portion 14b. A partition plate 35 (see FIG. 10) is fixed to the other end of the cylindrical body 30 at a position entering from the end, and an engagement pin 39 is fixed to a predetermined position of the partition plate 35. An electrode is provided at a predetermined position of the partition plate 35, and a lock mechanism (not shown) is formed on the peripheral edge of the partition plate 35. The electrodes (not shown) of the connector part 36 and the electrodes (not shown) of the connecting cylinder part are connected by wiring in the support column 14. The connector portion 36 is provided with electrodes 36a and 36b that come into contact with the electrodes 34a and 34b of the support column 12.

When engaging the connecting rod portion 14b of the second support column 14 in the connecting tube portion 12a of the first support column 12, a plurality of convex portions 14c on the peripheral surface of the connecting rod portion 14b are included in the connecting tube portion 12a. Since it engages in the state which contact | connected the surrounding surface, wobble does not arise in the connection of support | pillars 12 and 14. FIG. Moreover, since the recessed part which exists between a convex part forms a space between the internal peripheral surface of the connection cylinder part 12a, and the space becomes an air passage from which air escapes, the several convex part 14c is connected. Even if it is in close contact with the inner peripheral surface of the cylindrical portion 12a, the connecting rod portion can be easily inserted and removed. The column 14 is provided with pin receiving portions 32a and 32b into which the engagement pins 33a and 33b of the column 12 are inserted. However, their inner diameters are different, and a straight line passing through the center C2 of the column 14 is used. Since they are unevenly distributed on one semicircle side, they cannot be fitted unless the connecting portions of the support columns are matched. For this reason, when the support columns 12 and 14 are connected, the electrodes 34a and 34b and the electrodes 36a and 36b come into reliable contact with each other.

  When the connecting rod part 14b is quickly fitted into the connecting cylinder part 12a, the speed at which the air existing between the connecting cylinder part 12a and the connecting rod part 14b escapes through the air path between the protrusions is not in time. A phenomenon occurs in which the air pressure increases, resistance acts, and the connecting rod portion 14b cannot be easily fitted. Conversely, when the connecting rod part 14b is pulled out from the connecting cylinder part 12a, the air pressure in the space between the connecting cylinder part 12a and the connecting rod part 14b is reduced, and the resistance due to the suction force acts, so that the connecting rod part 14b is quickly moved. The phenomenon of not falling out can occur.

  However, since the air hole 37 is formed in the end surface of the connecting rod part 14b, when the connecting rod part 14b is pulled out of the connecting cylinder part 12a, if the air pressure in the space between the connecting rod part 14b and the connecting cylinder part 12a decreases, Since the air in the cylinder 30 moves and suppresses a decrease in air pressure, the connecting rod portion 14b can be easily pulled out from the connecting cylinder portion 12a. Conversely, when the connecting rod part 14b is fitted into the connecting cylinder part 12a, the air pressure in the space increases as the space between the connecting rod part 14b and the connecting cylinder part 12a becomes narrower. Since it is sent into the cylindrical body 30, the atmospheric pressure does not substantially increase, and the connecting rod portion 14b can be easily fitted into the connecting cylindrical portion 12a with almost no resistance.

Next, the front fan guard 16 and the rear fan guard 18 illustrated in FIGS. 1 to 3 are mainly intended to protect the user from the rotating fan 50. However, the rib of the front fan guard 16 is formed in a spiral shape. With this configuration, the air current is blown out in a spiral shape and has a function of blowing air further away. Further, as shown in FIG. 14, a magnet is provided on the outer peripheral inner surface side of the front fan guard 16. Specifically, four magnet storage portions 16b are provided on the outer periphery of the front fan guard 16, and a magnet 52 is inserted and fixed therein. Further, in order to prevent the airflow generated by the fan 50 from staying in the outer peripheral space of the front fan guard 16 and the rear fan guard 18 and reducing the blowing power, the front fan guard 16 and the rear fan guard are prevented. By providing several ribs 16d (see FIG. 14) perpendicular to the rotation direction of the fan 50 on the outer peripheral portion of 18 (19, 21), the forward air blowing capability is enhanced.

  As shown in FIGS. 3, 7, and 9, the rear fan guard 18 is provided so as to be in contact with the motor case 20. That is, a mounting plate 26 formed in a substantially trumpet shape is fixed to the front end side of the motor case 20, and the rear fan guard 18 is mounted on the mounting plate 26. As with the front fan guard 16, the rear fan guard 18 also has a rib 18a formed in a spiral shape. The function of blowing air farther is exhibited mainly by the spiral shape of the front fan guard 16, but the rear fan guard 18 is less effective than the front fan guard 16, but in order to enhance the effect, a spiral is used. The shape is adopted. A plurality of slits 26a are opened in the circumferential direction of the mounting plate 26, and air is sucked from the slits 26a.

  Next, FIG. 12 is a partial rear view of the rear fan guard of the electric fan of the first modified example, and the first modified example will be described in detail with reference to FIG. In the figure, an outer frame 45 of the rear fan guard 19 has an annular shape, and is supported by being connected to a plurality of ribs 40 a and 40 b extending radially from the motor case 20. An annular rib 41 concentric with the outer frame 45 connects the plurality of ribs 40a, 40b and the like. The plurality of radial ribs 40a and 40b are arranged around the motor case 20 at a predetermined interval, and a short rib 40c for connecting the motor case 20 and the annular rib 41 is provided between them. Two short ribs 40 d are provided to connect between the annular rib 41 and the outer frame 45. Under the above combination conditions, the periphery of the motor case 20 is arranged at equal intervals.

  In the first modified example, the rear fan guard 19 is configured by using the radial ribs 40a, 40b, 40c, and 40d. Therefore, the rear fan guard 18 causes a spiral airflow as in the above-described embodiment. Although there is no swirl airflow by the front fan guard 16, the function of flying the airflow far can be sufficiently exhibited. In the first modification, the spiral airflow is somewhat weaker than in the embodiment, but the rear fan is reinforced by ribs 40a and 40b extending radially from the motor case 20 and short ribs 40c and 40d. There is an advantage that the shape of the guard 19 is hardly deformed.

As shown in FIG. 15, metal plates 54 on which the magnets 52 of the front fan guard 16 are magnetically attached are inserted and fixed in the metal plate storage portions 19 b provided at four locations of the rear fan guard 19. In this state, when the front fan guard 16 shown in FIG. 14 is mounted, after the positioning rib 16a of the front fan guard 16 is inserted into the positioning portion 19a of the rear fan guard 19, the claw portion 16c of the front fan guard 16 is moved. By fitting into the claw receiving part 19c of the rear fan guard 19, it can be easily mounted with the help of the magnet 52, and the front fan guard 16 itself is not removed. In the present embodiment, the rear fan guard 19 is used in the assembly situation, but the same applies to other fan guards.

  Next, FIG. 13 is a partial rear view of the rear fan guard of the electric fan of the second modified example, and the second modified example will be described in detail with reference to FIG. In the figure, an outer frame 45 of the rear fan guard 21 has an annular shape, and is supported by being connected to a plurality of ribs 44 a and 44 b extending radially from the motor case 20. The annular ribs 42 and 43 concentrically with the outer frame 45 connect the plurality of ribs 40a and 40b. The plurality of radial ribs 44a and 44b are arranged around the motor case 20 at a predetermined interval, and one short rib 40c for connecting the motor case 20 and the annular rib 42 is provided between them. Two short ribs 44d that connect the annular ribs 42 and 43 are provided, and three short ribs 44e that connect the annular rib 43 and the outer frame 45 are provided. The short ribs 44c to 44e are arranged at equal intervals around the motor case 20 under the above combination conditions.

   In the second modified example, a spiral airflow is not generated in the rear fan guard 21 as in the first modified example. Since the ribs 44c to 44e shorter than the first modification and the plurality of annular ribs 42 and 43 are reinforced, the shape of the rear fan guard 21 is more than that of the first modification. There is an advantage that it is difficult to deform.

  The motor case 20 has a built-in motor (not shown). The electric motor can be used not only to rotate the fan 50 by supplying power but also to be used as a drive source for the swing motion.

As shown in FIG. 9, a handle 20 a is provided on the upper side of the electric motor case 20. The handle 20a is used when carrying the electric fan 100. Further, the handle 20a is formed with a U-shaped recess having an open top, and the remote controller 22 can be stored in the recess. Further, the bottom surface of the remote controller 22 is C-surface processed to improve the fitting into the recess. The handle 20a is formed along the longitudinal direction of the motor case 20, but may be formed so as to intersect the longitudinal direction.

   The remote controller 22 is for operating the electric fan 100 from a place that is some distance away from the operation panel 10b on the base 10. The remote controller 22 can be operated in the same manner as the operation panel 10c. By pressing a push button on the remote controller 22, a control signal is transmitted from the transmitter of the remote controller 22 to a light receiving unit provided on the base 10. Is done.

The remote control 22 is provided with a power switch, an air volume adjustment switch, a swing operation switch, a timer switch, and the like. A depression is provided on the surface of the push button so that the push button has a shape that fits the belly of the finger.
Furthermore, the upper surface of the push button is provided at a position lower than the upper surface of the remote controller 22 in order to prevent erroneous operation. In this way, it is necessary to depress the switch intentionally, so that the switch on the remote control is not accidentally depressed when held.

  Concave portions 22a are provided on both side surfaces of the remote controller 22, and convex portions 20d are provided at corresponding positions of the handle 20a. Thus, when the remote controller 22 is stored in the handle 20a, the remote controller 22 can be fixed at a fixed position, and can be easily held so that the remote controller is not detached from the handle 20a. .

  The remote controller 22 is stored in the handle 20a when not in use. At this time, the recess of the handle 20a is formed so that the upper surface of the remote control 22 is lower than the height of the side wall. As described above, since the push button is provided at a position lower than the upper surface of the remote controller 22, even if the electric fan is moved with the handle 20a when the remote controller 22 is stored in the handle 20a, the push button of the remote controller 22 is erroneously pressed. Can be prevented.

  Further, the push button of the remote controller 22 may have a convex shape protruding from the upper surface of the remote controller 22, but in this case, the height of the side wall of the concave portion of the handle 20 a is made higher than the upper surface of the push button on the remote controller 22. The same effect can be obtained.

Next, a use state is demonstrated using FIG.4, FIG.5, FIG.6.
FIG. 4 shows a state where the pedestal 10 and the motor case 20 are connected only by the first support column 12 (second use state). FIG. 5 shows a state where the pedestal 10 and the motor case 20 are connected only by the second support column 14 (third use state). FIG. 6 shows a state where the base 10 and the motor case 20 are directly connected (fourth use state).

About the length of the 1st support | pillar 12 and the 2nd support | pillar 14, since it exists in the relationship of 1st support | pillar 12> 2nd support | pillar 14, the height in each use condition is 1st use condition> The relationship is second usage state> third usage state> fourth usage state.

Next, the storage time of the electric fan 100 will be described with reference to FIG. When the electric fan 100 according to the present invention is stored, the connector cover 24 is removed from the storage portion 20c of the electric motor case 20, and is inserted into the support portion 10b of the base 10 into the storage portion 20c of the electric motor case 20. Since the connector cover 24 is provided with the finger pressing portion 24a (see FIG. 9), it can be easily removed. The removed connector cover 24 is attached to the connection portion 20b to which the support column is connected when the electric fan is stored. By doing so, the engaging pins 33a and 33b of the connecting portion of the 20b are not exposed but protected by the connector cover 24, so that the connecting portion of the 20b can be protected from dust and moisture, It is possible to reduce the probability of malfunction such as malfunction. FIG. 16 shows the inside of the connector cover 24, and engagement pin receiving holes 24b1 and 24b2 are provided. In addition, since the sizes of the engagement pin receiving holes 24b1 and 24b2 are different according to the difference in outer diameter of the engagement pins 33a and 33b, be careful of the insertion direction when attaching the connector cover 24 to the connection portion 20b. There is a need to.

However, when the electric fan is stored using the outer box, the outer box needs to be stored, and when using the fan, a space for storing the empty outer box is required. Moreover, even if the motor part of the electric fan is bent and the support is shortened, the length of the support can be reduced to only half due to the structure. Therefore, there is a limit to making the storage size compact, so if you try to store it with the outer box standing upright, you need to use a storage space with enough space in the height direction, and try to store it with the outer box laid down Then, a wide space is required.
The present invention has been made as a result of intensive studies to solve the above problems, and provides a fan that can be disassembled and assembled into a plurality of parts and can be stored in a small storage space when not in use. It is.

  Preferred embodiments of the present invention will be described below with reference to the drawings. This embodiment is an example, and the present invention is not limited to this.

  Hereinafter, an electric fan according to an embodiment of the present invention will be described with reference to the drawings. First, the overall configuration of the electric fan will be described with reference to FIGS. 1, 2 and 3. FIG. 1 is an overall perspective view of a state in which an electric fan according to an embodiment of the present invention is assembled, FIG. 2 is an overall rear view of the electric fan according to the embodiment as viewed from the back, and FIG. It is a partial expansion perspective view which shows the head of an electric fan.

FIG. 1 shows a fan 100 in a state of being assembled using all parts (first use state). The fan 100 includes a pedestal 10, a first column 12, a second column 14, and a front fan guard. 16, a rear fan guard 18, and an electric motor case 20. And the 1st support | pillar 12 is connected with the support | pillar part 10b of the base 10, and is further connected with the case connection part 20b (1st connection part) provided in the lower part of the motor case 20 via the 2nd support | pillar 14. ing.

  As shown in FIG. 2, a first button 10 a, a second button 12 a, and a third button 14 a are provided on the back surface of the electric fan 100, and the first button 10 b provided on the pedestal 10 b of the base 10 is provided. The button 10a is for releasing the connection between the column 10b of the base 10 and the first column 12, and the second button 12a is for releasing the connection between the first column 12 and the second column 14. The third button 14a is for releasing the connection between the second support column 14 and the case connecting portion 20b. FIG. 2 shows an example in which the first button 10a, the second button 12a, and the third button 14a are provided on the rear side of the electric fan 100. However, these buttons may be provided on the front surface or the side surface. .

As shown in FIG. 3, a storage portion 20c (second connection portion) of the connector cover 24 is formed on the rear side of the motor case 20, and the connector cover 24 is detachably attached to the storage portion 20c. ing. And since the storage part 20c is connected with the support | pillar part 10b of the base 10, when disassembling and storing each part of the electric fan 100 so that it may mention later, unlike the case connection part 20b, it is an electric motor. There is no need to connect. By adopting such a configuration, even if the operation panel 10c is erroneously operated when the electric fan 100 is stored, the fan is prevented from rotating.

  A pedestal 10 b to which the first support 12 is connected is erected on the pedestal 10, and a fan 50 (FIG. 15) that constitutes the head of the electric fan 100 through the first support 12 and the second support 14. The front fan guard 16, the rear fan guard 18, and the motor case 20 are supported. The pedestal 10 is provided with an operation panel 10c for controlling the power supply of the electric fan 100, the air volume adjustment, and the swinging motion.

  The pedestal 10 is formed in a circular shape, but is not limited thereto, and may be polygonal, rectangular, or any shape as long as the stability for maintaining the standing posture of the electric fan 100 can be secured.

  The 1st support | pillar 12 and the 2nd support | pillar 14 are the support | pillars comprised so that division | segmentation was possible. The length of the first support column 12 is configured to be different from that of the second support column 14. As shown in FIG. 8, small-diameter connecting rod portions 12b and 14b (connectors) are formed at one end portion of each support column 12 and 14, and the other end portion is a tube into which the connecting rod portions 12b and 14b can be inserted. Has become a department. Further, in this embodiment, a small-diameter connecting rod portion (not shown) is formed on the column portion 10b of the pedestal 10, and the motor case 20 is provided with a case connection portion 20b (FIG. 8). Fourteen connecting rod portions 12b and 14b can be inserted. In addition, each support | pillar 12,14, the base support | pillar part 10, and the case connection part 20b are provided with the electrode etc. so that it may mention later, and it supplies with electricity when it mutually connects.

  Thereby, the column part 10b, the columns 12, 14 and the case connection unit 20b of the base 10 can be connected to each other in a detachable manner, and the order of connecting the columns 12, 14 may be changed. It is possible to connect even if only the support is used. Therefore, if the lengths of the two columns are different, the height can be adjusted depending on the column used. For example, as shown in FIG. 4, the first support column 12 having a long length is connected to the support column portion 10 b of the base 10, and the height of the electric fan 100 is compared with the case where both the support columns 12 and 14 are used. It can be set low. Moreover, as shown in FIG. 5, the 2nd support | pillar 14 with short length is connected with the support | pillar part 10b of the base 10, and the height of the electric fan 100 can be set still lower.

  And as shown in FIG. 6, when the support | pillar part 10b of the base 10 and the case connection part 20b are directly connected, without using the 1st, 2nd support | pillars 12 and 14, the height of the electric fan 100 shall be made the lowest. You can also. In this case, if the head part of the electric fan 100 is turned upward, the electric fan 100 can blow cool air drifting near the floor to the upper part of the room and stir the air in the entire room. In particular, when performing an operation of cooling the entire room using an air conditioner (not shown) in the summer, it is suitable for an operation of stirring the air in the room to uniformly cool the entire air.

  In addition, the connection means for enabling the column 10b, the columns 12, 14 and the case connection 20b of the base 10 to be detachably connected to each other is limited to the fitting type configuration as in the above-described embodiment. For example, a screw type, a sleeve joint type, or the like may be adopted.

  Next, the 1st support | pillar and 2nd support | pillar used for the electric fan which concerns on 1st Embodiment are demonstrated in detail using FIG.10 and FIG.11. FIG. 10 is an enlarged perspective view showing the configuration of the first support column, and FIG. 11 is an enlarged perspective view showing the configuration of the second support column.

As shown in FIG. 10, the 1st support | pillar 12 is comprised by the cylindrical cylinder 29 shape | molded by resin, The one end becomes the small diameter connection rod part 12b, and the surrounding surface of the connection rod part 12b A plurality of convex portions 12 c are formed in the axial direction of the cylindrical body 29. Furthermore, a lock mechanism 31a and a second button 12a for operating the lock mechanism 31a are provided at one end of the cylindrical body 29, and a connector portion (not shown) is provided at the end surface of the connecting rod portion 12b. Yes. And the partition plate 35 is being fixed to the position which entered from the connection cylinder part 12d of the other end of the cylinder 29, and the engagement pins 33a and 33b are being fixed to the predetermined position of the partition plate 35. As shown in FIG. Furthermore, electrodes 34 a, 34 b, 34 c are provided at predetermined positions of the partition plate 35, and a lock mechanism 31 b is configured at the peripheral edge of the partition plate 35. And the electrode of a connector part and electrode 34a, 34b are connected by the wiring in a support | pillar. Reference numeral 34c denotes an electrode that is not used in this example.

  The pin outer diameters of the engaging pins 33a and 33b are slightly different. Further, these two are unevenly distributed on one semicircular side with respect to a straight line passing through the center C1 of the partition plate 35 of the support column 12.

  As shown in FIG. 11, the 2nd support | pillar 14 is comprised similarly to the 1st support | pillar 12, and structures other than the length of a support | pillar are the same. That is, the second support column 14 is configured by a cylindrical tube body 30 formed of resin, and one end thereof is a small-diameter connecting rod portion 14b, and a plurality of protrusions are formed on the peripheral surface of the connecting rod portion 14b. The portion 14 c is formed in the axial direction of the cylindrical body 30. Furthermore, a lock mechanism 38 and a third button 14a for operating the lock mechanism 38 are provided at one end of the cylindrical body 30, and a connector portion 36 is provided at the end surface of the connecting rod portion 14b. A partition plate 35 (see FIG. 10) is fixed to the other end of the cylindrical body 30 at a position entering from the end, and an engagement pin 39 is fixed to a predetermined position of the partition plate 35. An electrode is provided at a predetermined position of the partition plate 35, and a lock mechanism (not shown) is formed on the peripheral edge of the partition plate 35. The electrodes (not shown) of the connector part 36 and the electrodes (not shown) of the connecting cylinder part are connected by wiring in the support column 14. The connector portion 36 is provided with electrodes 36a and 36b that come into contact with the electrodes 34a and 34b of the support column 12.

When the connecting rod portion 14b of the second support column 14 is engaged with the connecting cylinder portion 12d of the first support column 12, a plurality of convex portions 14c on the peripheral surface of the connecting rod portion 14b are included in the connecting tube portion 12d . Since it engages in the state which contact | connected the surrounding surface, wobble does not arise in the connection of support | pillars 12 and 14. FIG. Moreover, since the recessed part which exists between a convex part forms the space between the internal peripheral surface of 12 d of connection cylinder parts, and the space becomes an air path from which air escapes, the several convex part 14c is connected. Even if it is in close contact with the inner peripheral surface of the cylindrical portion 12d , the connecting rod portion can be easily inserted and removed. The column 14 is provided with pin receiving portions 32a and 32b into which the engagement pins 33a and 33b of the column 12 are inserted. However, their inner diameters are different, and a straight line passing through the center C2 of the column 14 is used. Since they are unevenly distributed on one semicircle side, they cannot be fitted unless the connecting portions of the support columns are matched. For this reason, when the support columns 12 and 14 are connected, the electrodes 34a and 34b and the electrodes 36a and 36b come into reliable contact with each other.

When fitted quickly connecting rod portion 14b in the connecting tube portion 12d is too late speed air located between the connecting rod portion 14b and the connecting tube portion 12d comes out through the air passage between the convex portion and the convex portion, A phenomenon occurs in which the air pressure increases, resistance acts, and the connecting rod portion 14b cannot be easily fitted. Conversely, when withdrawing the connecting rod portion 14b from the connecting tubular portion 12d, and air pressure drops in the space between the connecting rod portion 14b and the connecting tubular portion 12d, work resistance by the suction force, quickly connecting rod portion 14b The phenomenon of not falling out can occur.

However, since the air hole 37 is formed in the end surface of the connecting rod part 14b, when the connecting rod part 14b is pulled out of the connecting cylinder part 12d , the air pressure in the space between the connecting rod part 14b and the connecting cylinder part 12d decreases. Since the air in the cylinder 30 moves and suppresses a decrease in air pressure, the connecting rod portion 14b can be easily pulled out from the connecting cylinder portion 12d . Conversely, when fitting the connecting rod portion 14b in the connecting tube portion 12d, according to the space between the connecting cylinder portion 12d and the connecting rod portion 14b is narrowed, although pressure of the space increases, the air passes through the vent hole 37 Since it is sent into the cylindrical body 30, the atmospheric pressure does not substantially increase, and the connecting rod portion 14b can be easily fitted into the connecting cylindrical portion 12d with almost no resistance.

  Next, the front fan guard 16 and the rear fan guard 18 illustrated in FIGS. 1 to 3 are mainly intended to protect the user from the rotating fan 50. However, the rib of the front fan guard 16 is formed in a spiral shape. With this configuration, the air current is blown out in a spiral shape and has a function of blowing air further away. Further, as shown in FIG. 14, a magnet is provided on the outer peripheral inner surface side of the front fan guard 16. Specifically, four magnet storage portions 16b are provided on the outer periphery of the front fan guard 16, and a magnet 52 is inserted and fixed therein. Further, in order to prevent the airflow generated by the fan 50 from staying in the outer peripheral space of the front fan guard 16 and the rear fan guard 18 and reducing the blowing power, the front fan guard 16 and the rear fan guard are prevented. By providing several ribs 16d (see FIG. 14) perpendicular to the rotation direction of the fan 50 on the outer peripheral portion of 18 (19, 21), the forward air blowing capability is enhanced.

  As shown in FIGS. 3, 7, and 9, the rear fan guard 18 is provided so as to be in contact with the motor case 20. That is, a mounting plate 26 formed in a substantially trumpet shape is fixed to the front end side of the motor case 20, and the rear fan guard 18 is mounted on the mounting plate 26. As with the front fan guard 16, the rear fan guard 18 also has a rib 18a formed in a spiral shape. The function of blowing air farther is exhibited mainly by the spiral shape of the front fan guard 16, but the rear fan guard 18 is less effective than the front fan guard 16, but in order to enhance the effect, a spiral is used. The shape is adopted. A plurality of slits 26a are opened in the circumferential direction of the mounting plate 26, and air is sucked from the slits 26a.

  Next, FIG. 12 is a partial rear view of the rear fan guard of the electric fan of the first modified example, and the first modified example will be described in detail with reference to FIG. In the figure, an outer frame 45 of the rear fan guard 19 has an annular shape, and is supported by being connected to a plurality of ribs 40 a and 40 b extending radially from the motor case 20. An annular rib 41 concentric with the outer frame 45 connects the plurality of ribs 40a, 40b and the like. The plurality of radial ribs 40a and 40b are arranged around the motor case 20 at a predetermined interval, and a short rib 40c for connecting the motor case 20 and the annular rib 41 is provided between them. Two short ribs 40 d are provided to connect between the annular rib 41 and the outer frame 45. Under the above combination conditions, the periphery of the motor case 20 is arranged at equal intervals.

  In the first modified example, the rear fan guard 19 is configured by using the radial ribs 40a, 40b, 40c, and 40d. Therefore, the rear fan guard 18 causes a spiral airflow as in the above-described embodiment. Although there is no swirl airflow by the front fan guard 16, the function of flying the airflow far can be sufficiently exhibited. In the first modification, the spiral airflow is somewhat weaker than in the embodiment, but the rear fan is reinforced by ribs 40a and 40b extending radially from the motor case 20 and short ribs 40c and 40d. There is an advantage that the shape of the guard 19 is hardly deformed.

  As shown in FIG. 15, metal plates 54 on which the magnets 52 of the front fan guard 16 are magnetically attached are inserted and fixed in the metal plate storage portions 19 b provided at four locations of the rear fan guard 19. In this state, when the front fan guard 16 shown in FIG. 14 is mounted, after the positioning rib 16a of the front fan guard 16 is inserted into the positioning portion 19a of the rear fan guard 19, the claw portion 16c of the front fan guard 16 is moved. By fitting into the claw receiving part 19c of the rear fan guard 19, it can be easily mounted with the help of the magnet 52, and the front fan guard 16 itself is not removed. In the present embodiment, the rear fan guard 19 is used in the assembly situation, but the same applies to other fan guards.

  Next, FIG. 13 is a partial rear view of the rear fan guard of the electric fan of the second modified example, and the second modified example will be described in detail with reference to FIG. In the figure, an outer frame 45 of the rear fan guard 21 has an annular shape, and is supported by being connected to a plurality of ribs 44 a and 44 b extending radially from the motor case 20. The annular ribs 42 and 43 concentrically with the outer frame 45 connect the plurality of ribs 40a and 40b. The plurality of radial ribs 44a and 44b are arranged around the motor case 20 at a predetermined interval, and one short rib 40c for connecting the motor case 20 and the annular rib 42 is provided between them. Two short ribs 44d that connect the annular ribs 42 and 43 are provided, and three short ribs 44e that connect the annular rib 43 and the outer frame 45 are provided. The short ribs 44c to 44e are arranged at equal intervals around the motor case 20 under the above combination conditions.

   In the second modified example, a spiral airflow is not generated in the rear fan guard 21 as in the first modified example. Since the ribs 44c to 44e shorter than the first modification and the plurality of annular ribs 42 and 43 are reinforced, the shape of the rear fan guard 21 is more than that of the first modification. There is an advantage that it is difficult to deform.

  The motor case 20 has a built-in motor (not shown). The electric motor can be used not only to rotate the fan 50 by supplying power but also to be used as a drive source for the swing motion.

  As shown in FIG. 9, a handle 20 a is provided on the upper side of the electric motor case 20. The handle 20a is used when carrying the electric fan 100. Further, the handle 20a is formed with a U-shaped recess having an open top, and the remote controller 22 can be stored in the recess. Further, the bottom surface of the remote controller 22 is C-surface processed to improve the fitting into the recess. The handle 20a is formed along the longitudinal direction of the motor case 20, but may be formed so as to intersect the longitudinal direction.

   The remote controller 22 is for operating the electric fan 100 from a place that is some distance away from the operation panel 10b on the base 10. The remote controller 22 can be operated in the same manner as the operation panel 10c. By pressing a push button on the remote controller 22, a control signal is transmitted from the transmitter of the remote controller 22 to a light receiving unit provided on the base 10. Is done.

The remote control 22 is provided with a power switch, an air volume adjustment switch, a swing operation switch, a timer switch, and the like. A depression is provided on the surface of the push button so that the push button has a shape that fits the belly of the finger.
Furthermore, the upper surface of the push button is provided at a position lower than the upper surface of the remote controller 22 in order to prevent erroneous operation. In this way, it is necessary to depress the switch intentionally, so that the switch on the remote control is not accidentally depressed when held.

  Concave portions 22a are provided on both side surfaces of the remote controller 22, and convex portions 20d are provided at corresponding positions of the handle 20a. Thus, when the remote controller 22 is stored in the handle 20a, the remote controller 22 can be fixed at a fixed position, and can be easily held so that the remote controller is not detached from the handle 20a. .

  The remote controller 22 is stored in the handle 20a when not in use. At this time, the recess of the handle 20a is formed so that the upper surface of the remote control 22 is lower than the height of the side wall. As described above, since the push button is provided at a position lower than the upper surface of the remote controller 22, even if the electric fan is moved with the handle 20a when the remote controller 22 is stored in the handle 20a, the push button of the remote controller 22 is erroneously pressed. Can be prevented.

  Further, the push button of the remote controller 22 may have a convex shape protruding from the upper surface of the remote controller 22, but in this case, the height of the side wall of the concave portion of the handle 20 a is made higher than the upper surface of the push button on the remote controller 22. The same effect can be obtained.

Next, a use state is demonstrated using FIG.4, FIG.5, FIG.6.
FIG. 4 shows a state where the pedestal 10 and the motor case 20 are connected only by the first support column 12 (second use state). FIG. 5 shows a state where the pedestal 10 and the motor case 20 are connected only by the second support column 14 (third use state). FIG. 6 shows a state where the base 10 and the motor case 20 are directly connected (fourth use state).

  About the length of the 1st support | pillar 12 and the 2nd support | pillar 14, since it exists in the relationship of 1st support | pillar 12> 2nd support | pillar 14, the height in each use condition is 1st use condition> The relationship is second usage state> third usage state> fourth usage state.

Next, the storage time of the electric fan 100 will be described with reference to FIG. When the electric fan 100 according to the present invention is housed, the connector cover 24 is removed from the housing portion 20c of the electric motor case 20, so that the fan 50 and the front and rear fan guards 16 and 18 for housing the fan 50 are in an upward state. The storage portion 20c of the electric motor case 20 is inserted and connected to the tip of the portion 10b.

Since the connector cover 24 is provided with the finger pressing portion 24a (see FIG. 9), it can be easily removed. The removed connector cover 24 is attached to the case connecting portion 20b to which the support column is connected when the electric fan is stored. By doing so, the engaging pins 33a and 33b of the case connecting portion 20b are not exposed but are protected by the connector cover 24, so that the connecting portion of the case connecting portion 20b can be protected from dust and moisture. This makes it possible to reduce the probability of malfunctions such as malfunctions. FIG. 16 shows the inside of the connector cover 24, and engagement pin receiving holes 24b1 and 24b2 are provided. Further, since the sizes of the engagement pin receiving holes 24b1 and 24b2 are different according to the difference in the outer diameters of the engagement pins 33a and 33b, when attaching the connector cover 24 to the case connecting portion 20b , You need to be careful.

  17 and 18 show a deformed connector cover 25 for facilitating smooth engagement of the engaging pins 33a and 33b. Specifically, two U-shaped recesses 25c are provided on the cylindrical outer periphery, and two engagement pin receiving portions 25b are provided on the bottom side of the recesses 25c. Therefore, the positional relationship into which the engagement pins 33a and 33b are inserted can be confirmed, and a direction error at the time of attachment can be eliminated.

At this time, the first support column 12 and the second support column 14 are accommodated in a horizontally placed state in a space generated in the rear surface portion of the motor case 20 and the upper surface portion of the base 10 in a disassembled state .

  By storing in this way, it becomes possible to suppress the height to be lower than that of a fan having a structure in which a conventional support can be expanded and contracted. Further, if the diameter of the pedestal 10 and the diameter of the fan guard are substantially the same, since the fan is stored in a shape close to a cylinder, the useless space in the storage space is reduced as compared with the conventional one.

  Note that the present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the scope of the present invention.

  The present invention relates to a fan that can be disassembled and assembled.

  The electric fan basically includes a support extending from a base, an electric motor case installed on the support, and a fan guard. When such a fan is used and stored in the outer box, the supporting column connecting the pedestal and the fan guard is long, resulting in a useless space between the fan guard and the pedestal, and the stored outer box. The size of the container becomes large and efficient transportation becomes difficult.

  Also, when the usage frequency is low, such as in winter, the electric fan is stored in the storage, etc., but a wasteful space is created during storage as in the case of transportation, and limited storage space such as storage is effective. Inconvenience that it is not possible to use it for the purpose of placing other storage items.

Under such circumstances, various ideas for reducing useless space have been proposed.
For example, Patent Document 1 discloses a fan in which a fan guard and a fan are disassembled from a main body, the main body is bent in a motor portion from a neck portion, and a telescopic support is contracted, and is packed in an outer box using a buffer. Is disclosed.

  According to this, by bending and storing the fan head from the neck portion and reducing the height at the time of storage, the height of the exterior box can be reduced and transportation is facilitated.

JP-A-6-31767

However, when the electric fan is stored using the outer box, the outer box needs to be stored, and when using the fan, a space for storing the empty outer box is required. Moreover, even if the motor part of the electric fan is bent and the support is shortened, the length of the support can be reduced to only half due to the structure. Therefore, there is a limit to making the storage size compact, so if you try to store it with the outer box standing upright, you need to use a storage space with enough space in the height direction, and try to store it with the outer box laid down Then, a wide space is required.
The present invention has been made as a result of intensive studies to solve the above problems, and provides a fan that can be disassembled and assembled into a plurality of parts and can be stored in a small storage space when not in use. It is.

  Preferred embodiments of the present invention will be described below with reference to the drawings. This embodiment is an example, and the present invention is not limited to this.

  Hereinafter, an electric fan according to an embodiment of the present invention will be described with reference to the drawings. First, the overall configuration of the electric fan will be described with reference to FIGS. 1, 2 and 3. FIG. 1 is an overall perspective view of a state in which an electric fan according to an embodiment of the present invention is assembled, FIG. 2 is an overall rear view of the electric fan according to the embodiment as viewed from the back, and FIG. It is a partial expansion perspective view which shows the head of an electric fan.

  FIG. 1 shows a fan 100 in a state of being assembled using all parts (first use state). The fan 100 includes a pedestal 10, a first column 12, a second column 14, and a front fan guard. 16, a rear fan guard 18, and an electric motor case 20. And the 1st support | pillar 12 is connected with the support | pillar part 10b of the base 10, and is further connected with the case connection part 20b (1st connection part) provided in the lower part of the motor case 20 via the 2nd support | pillar 14. ing.

  As shown in FIG. 2, a first button 10 a, a second button 12 a, and a third button 14 a are provided on the back surface of the electric fan 100, and the first button 10 b provided on the pedestal 10 b of the base 10 is provided. The button 10a is for releasing the connection between the column 10b of the base 10 and the first column 12, and the second button 12a is for releasing the connection between the first column 12 and the second column 14. The third button 14a is for releasing the connection between the second support column 14 and the case connecting portion 20b. FIG. 2 shows an example in which the first button 10a, the second button 12a, and the third button 14a are provided on the rear side of the electric fan 100. However, these buttons may be provided on the front surface or the side surface. .

  As shown in FIG. 3, a storage part 20c (second connection part) of the connector cover 24 is formed on the rear side of the motor case 20, and the connector cover 24 is detachably attached to the storage part 20c. ing. And since the storage part 20c is connected with the support | pillar part 10b of the base 10, when disassembling and storing each part of the electric fan 100 so that it may mention later, unlike the case connection part 20b, it is an electric motor. There is no need to connect. By adopting such a configuration, even if the operation panel 10c is erroneously operated when the electric fan 100 is stored, the fan is prevented from rotating.

  A pedestal 10 b to which the first support 12 is connected is erected on the pedestal 10, and a fan 50 (FIG. 15) that constitutes the head of the electric fan 100 through the first support 12 and the second support 14. The front fan guard 16, the rear fan guard 18, and the motor case 20 are supported. The pedestal 10 is provided with an operation panel 10c for controlling the power supply of the electric fan 100, the air volume adjustment, and the swinging motion.

  The pedestal 10 is formed in a circular shape, but is not limited thereto, and may be polygonal, rectangular, or any shape as long as the stability for maintaining the standing posture of the electric fan 100 can be secured.

The 1st support | pillar 12 and the 2nd support | pillar 14 are the support | pillars comprised so that division | segmentation was possible. The length of the first support column 12 is configured to be different from that of the second support column 14. As shown in FIG. 8, small-diameter connecting rod portions 12b and 14b (connectors) are formed at one end portion of each support column 12 and 14, and the other end portion is a tube into which the connecting rod portions 12b and 14b can be inserted. Has become a department. Further, in this embodiment, a small-diameter connecting rod portion (not shown) is formed on the column portion 10b of the pedestal 10, and the motor case 20 is provided with a case connection portion 20b (FIG. 8). Fourteen connecting rod portions 12b and 14b can be inserted. In addition, each support | pillar 12,14, the base support | pillar part 10b, and the case connection part 20b are equipped with the electrode etc. so that it may mention later, and when it mutually connects, it will supply with electricity.

  Thereby, the column part 10b, the columns 12, 14 and the case connection unit 20b of the base 10 can be connected to each other in a detachable manner, and the order of connecting the columns 12, 14 may be changed. It is possible to connect even if only the support is used. Therefore, if the lengths of the two columns are different, the height can be adjusted depending on the column used. For example, as shown in FIG. 4, the first support column 12 having a long length is connected to the support column portion 10 b of the base 10, and the height of the electric fan 100 is compared with the case where both the support columns 12 and 14 are used. It can be set low. Moreover, as shown in FIG. 5, the 2nd support | pillar 14 with short length is connected with the support | pillar part 10b of the base 10, and the height of the electric fan 100 can be set still lower.

  And as shown in FIG. 6, when the support | pillar part 10b of the base 10 and the case connection part 20b are directly connected, without using the 1st, 2nd support | pillars 12 and 14, the height of the electric fan 100 shall be made the lowest. You can also. In this case, if the head part of the electric fan 100 is turned upward, the electric fan 100 can blow cool air drifting near the floor to the upper part of the room and stir the air in the entire room. In particular, when performing an operation of cooling the entire room using an air conditioner (not shown) in the summer, it is suitable for an operation of stirring the air in the room to uniformly cool the entire air.

  In addition, the connection means for enabling the column 10b, the columns 12, 14 and the case connection 20b of the base 10 to be detachably connected to each other is limited to the fitting type configuration as in the above-described embodiment. For example, a screw type, a sleeve joint type, or the like may be adopted.

  Next, the 1st support | pillar and 2nd support | pillar used for the electric fan which concerns on 1st Embodiment are demonstrated in detail using FIG.10 and FIG.11. FIG. 10 is an enlarged perspective view showing the configuration of the first support column, and FIG. 11 is an enlarged perspective view showing the configuration of the second support column.

  As shown in FIG. 10, the 1st support | pillar 12 is comprised by the cylindrical cylinder 29 shape | molded by resin, The one end becomes the small diameter connection rod part 12b, and the surrounding surface of the connection rod part 12b A plurality of convex portions 12 c are formed in the axial direction of the cylindrical body 29. Furthermore, a lock mechanism 31a and a second button 12a for operating the lock mechanism 31a are provided at one end of the cylindrical body 29, and a connector portion (not shown) is provided at the end surface of the connecting rod portion 12b. Yes. And the partition plate 35 is being fixed to the position which entered from the connection cylinder part 12d of the other end of the cylinder 29, and the engagement pins 33a and 33b are being fixed to the predetermined position of the partition plate 35. As shown in FIG. Furthermore, electrodes 34 a, 34 b, 34 c are provided at predetermined positions of the partition plate 35, and a lock mechanism 31 b is configured at the peripheral edge of the partition plate 35. And the electrode of a connector part and electrode 34a, 34b are connected by the wiring in a support | pillar. Reference numeral 34c denotes an electrode that is not used in this example.

  The pin outer diameters of the engaging pins 33a and 33b are slightly different. Further, these two are unevenly distributed on one semicircular side with respect to a straight line passing through the center C1 of the partition plate 35 of the support column 12.

  As shown in FIG. 11, the 2nd support | pillar 14 is comprised similarly to the 1st support | pillar 12, and structures other than the length of a support | pillar are the same. That is, the second support column 14 is configured by a cylindrical tube body 30 formed of resin, and one end thereof is a small-diameter connecting rod portion 14b, and a plurality of protrusions are formed on the peripheral surface of the connecting rod portion 14b. The portion 14 c is formed in the axial direction of the cylindrical body 30. Furthermore, a lock mechanism 38 and a third button 14a for operating the lock mechanism 38 are provided at one end of the cylindrical body 30, and a connector portion 36 is provided at the end surface of the connecting rod portion 14b. A partition plate 35 (see FIG. 10) is fixed to the other end of the cylindrical body 30 at a position entering from the end, and an engagement pin 39 is fixed to a predetermined position of the partition plate 35. An electrode is provided at a predetermined position of the partition plate 35, and a lock mechanism (not shown) is formed on the peripheral edge of the partition plate 35. The electrodes (not shown) of the connector part 36 and the electrodes (not shown) of the connecting cylinder part are connected by wiring in the support column 14. The connector portion 36 is provided with electrodes 36a and 36b that come into contact with the electrodes 34a and 34b of the support column 12.

  When the connecting rod portion 14b of the second support column 14 is engaged with the connecting cylinder portion 12d of the first support column 12, a plurality of convex portions 14c on the peripheral surface of the connecting rod portion 14b are included in the connecting tube portion 12d. Since it engages in the state which contact | connected the surrounding surface, wobble does not arise in the connection of support | pillars 12 and 14. FIG. Moreover, since the recessed part which exists between a convex part forms the space between the internal peripheral surface of 12 d of connection cylinder parts, and the space becomes an air path from which air escapes, the several convex part 14c is connected. Even if it is in close contact with the inner peripheral surface of the cylindrical portion 12d, the connecting rod portion can be easily inserted and removed. The column 14 is provided with pin receiving portions 32a and 32b into which the engagement pins 33a and 33b of the column 12 are inserted. However, their inner diameters are different, and a straight line passing through the center C2 of the column 14 is used. Since they are unevenly distributed on one semicircle side, they cannot be fitted unless the connecting portions of the support columns are matched. For this reason, when the support columns 12 and 14 are connected, the electrodes 34a and 34b and the electrodes 36a and 36b come into reliable contact with each other.

  When the connecting rod part 14b is quickly fitted into the connecting cylinder part 12d, the speed at which the air existing between the connecting cylinder part 12d and the connecting rod part 14b escapes through the air path between the protrusions is not in time. A phenomenon occurs in which the air pressure increases, resistance acts, and the connecting rod portion 14b cannot be easily fitted. On the other hand, when the connecting rod part 14b is pulled out from the connecting cylinder part 12d, the air pressure in the space between the connecting cylinder part 12d and the connecting rod part 14b decreases, and the resistance due to the suction force acts, so that the connecting rod part 14b is quickly moved. The phenomenon of not falling out can occur.

  However, since the air hole 37 is formed in the end surface of the connecting rod part 14b, when the connecting rod part 14b is pulled out of the connecting cylinder part 12d, the air pressure in the space between the connecting rod part 14b and the connecting cylinder part 12d decreases. Since the air in the cylinder 30 moves and suppresses a decrease in air pressure, the connecting rod portion 14b can be easily pulled out from the connecting cylinder portion 12d. Conversely, when the connecting rod portion 14b is fitted into the connecting cylinder portion 12d, the air pressure in the space increases as the space between the connecting rod portion 14b and the connecting cylinder portion 12d becomes narrower. Since it is sent into the cylindrical body 30, the atmospheric pressure does not substantially increase, and the connecting rod portion 14b can be easily fitted into the connecting cylindrical portion 12d with almost no resistance.

  Next, the front fan guard 16 and the rear fan guard 18 illustrated in FIGS. 1 to 3 are mainly intended to protect the user from the rotating fan 50. However, the rib of the front fan guard 16 is formed in a spiral shape. With this configuration, the air current is blown out in a spiral shape and has a function of blowing air further away. Further, as shown in FIG. 14, a magnet is provided on the outer peripheral inner surface side of the front fan guard 16. Specifically, four magnet storage portions 16b are provided on the outer periphery of the front fan guard 16, and a magnet 52 is inserted and fixed therein. Further, in order to prevent the airflow generated by the fan 50 from staying in the outer peripheral space of the front fan guard 16 and the rear fan guard 18 and reducing the blowing power, the front fan guard 16 and the rear fan guard are prevented. By providing several ribs 16d (see FIG. 14) perpendicular to the rotation direction of the fan 50 on the outer peripheral portion of 18 (19, 21), the forward air blowing capability is enhanced.

  As shown in FIGS. 3, 7, and 9, the rear fan guard 18 is provided so as to be in contact with the motor case 20. That is, a mounting plate 26 formed in a substantially trumpet shape is fixed to the front end side of the motor case 20, and the rear fan guard 18 is mounted on the mounting plate 26. As with the front fan guard 16, the rear fan guard 18 also has a rib 18a formed in a spiral shape. The function of blowing air farther is exhibited mainly by the spiral shape of the front fan guard 16, but the rear fan guard 18 is less effective than the front fan guard 16, but in order to enhance the effect, a spiral is used. The shape is adopted. A plurality of slits 26a are opened in the circumferential direction of the mounting plate 26, and air is sucked from the slits 26a.

  Next, FIG. 12 is a partial rear view of the rear fan guard of the electric fan of the first modified example, and the first modified example will be described in detail with reference to FIG. In the figure, an outer frame 45 of the rear fan guard 19 has an annular shape, and is supported by being connected to a plurality of ribs 40 a and 40 b extending radially from the motor case 20. An annular rib 41 concentric with the outer frame 45 connects the plurality of ribs 40a, 40b and the like. The plurality of radial ribs 40a and 40b are arranged around the motor case 20 at a predetermined interval, and a short rib 40c for connecting the motor case 20 and the annular rib 41 is provided between them. Two short ribs 40 d are provided to connect between the annular rib 41 and the outer frame 45. Under the above combination conditions, the periphery of the motor case 20 is arranged at equal intervals.

  In the first modified example, the rear fan guard 19 is configured by using the radial ribs 40a, 40b, 40c, and 40d. Therefore, the rear fan guard 18 causes a spiral airflow as in the above-described embodiment. Although there is no swirl airflow by the front fan guard 16, the function of flying the airflow far can be sufficiently exhibited. In the first modification, the spiral airflow is somewhat weaker than in the embodiment, but the rear fan is reinforced by ribs 40a and 40b extending radially from the motor case 20 and short ribs 40c and 40d. There is an advantage that the shape of the guard 19 is hardly deformed.

  As shown in FIG. 15, metal plates 54 on which the magnets 52 of the front fan guard 16 are magnetically attached are inserted and fixed in the metal plate storage portions 19 b provided at four locations of the rear fan guard 19. In this state, when the front fan guard 16 shown in FIG. 14 is mounted, after the positioning rib 16a of the front fan guard 16 is inserted into the positioning portion 19a of the rear fan guard 19, the claw portion 16c of the front fan guard 16 is moved. By fitting into the claw receiving part 19c of the rear fan guard 19, it can be easily mounted with the help of the magnet 52, and the front fan guard 16 itself is not removed. In the present embodiment, the rear fan guard 19 is used in the assembly situation, but the same applies to other fan guards.

  Next, FIG. 13 is a partial rear view of the rear fan guard of the electric fan of the second modified example, and the second modified example will be described in detail with reference to FIG. In the figure, an outer frame 45 of the rear fan guard 21 has an annular shape, and is supported by being connected to a plurality of ribs 44 a and 44 b extending radially from the motor case 20. The annular ribs 42 and 43 concentrically with the outer frame 45 connect the plurality of ribs 40a and 40b. The plurality of radial ribs 44a and 44b are arranged around the motor case 20 at a predetermined interval, and one short rib 40c for connecting the motor case 20 and the annular rib 42 is provided between them. Two short ribs 44d that connect the annular ribs 42 and 43 are provided, and three short ribs 44e that connect the annular rib 43 and the outer frame 45 are provided. The short ribs 44c to 44e are arranged at equal intervals around the motor case 20 under the above combination conditions.

   In the second modified example, a spiral airflow is not generated in the rear fan guard 21 as in the first modified example. Since the ribs 44c to 44e shorter than the first modification and the plurality of annular ribs 42 and 43 are reinforced, the shape of the rear fan guard 21 is more than that of the first modification. There is an advantage that it is difficult to deform.

  The motor case 20 has a built-in motor (not shown). The electric motor can be used not only to rotate the fan 50 by supplying power but also to be used as a drive source for the swing motion.

  As shown in FIG. 9, a handle 20 a is provided on the upper side of the electric motor case 20. The handle 20a is used when carrying the electric fan 100. Further, the handle 20a is formed with a U-shaped recess having an open top, and the remote controller 22 can be stored in the recess. Further, the bottom surface of the remote controller 22 is C-surface processed to improve the fitting into the recess. The handle 20a is formed along the longitudinal direction of the motor case 20, but may be formed so as to intersect the longitudinal direction.

   The remote controller 22 is for operating the electric fan 100 from a place that is some distance away from the operation panel 10b on the base 10. The remote controller 22 can be operated in the same manner as the operation panel 10c. By pressing a push button on the remote controller 22, a control signal is transmitted from the transmitter of the remote controller 22 to a light receiving unit provided on the base 10. Is done.

The remote control 22 is provided with a power switch, an air volume adjustment switch, a swing operation switch, a timer switch, and the like. A depression is provided on the surface of the push button so that the push button has a shape that fits the belly of the finger.
Furthermore, the upper surface of the push button is provided at a position lower than the upper surface of the remote controller 22 in order to prevent erroneous operation. In this way, it is necessary to depress the switch intentionally, so that the switch on the remote control is not accidentally depressed when held.

  Concave portions 22a are provided on both side surfaces of the remote controller 22, and convex portions 20d are provided at corresponding positions of the handle 20a. Thus, when the remote controller 22 is stored in the handle 20a, the remote controller 22 can be fixed at a fixed position, and can be easily held so that the remote controller is not detached from the handle 20a. .

  The remote controller 22 is stored in the handle 20a when not in use. At this time, the recess of the handle 20a is formed so that the upper surface of the remote control 22 is lower than the height of the side wall. As described above, since the push button is provided at a position lower than the upper surface of the remote controller 22, even if the electric fan is moved with the handle 20a when the remote controller 22 is stored in the handle 20a, the push button of the remote controller 22 is erroneously pressed. Can be prevented.

  Further, the push button of the remote controller 22 may have a convex shape protruding from the upper surface of the remote controller 22, but in this case, the height of the side wall of the concave portion of the handle 20 a is made higher than the upper surface of the push button on the remote controller 22. The same effect can be obtained.

Next, a use state is demonstrated using FIG.4, FIG.5, FIG.6.
FIG. 4 shows a state where the pedestal 10 and the motor case 20 are connected only by the first support column 12 (second use state). FIG. 5 shows a state where the pedestal 10 and the motor case 20 are connected only by the second support column 14 (third use state). FIG. 6 shows a state where the base 10 and the motor case 20 are directly connected (fourth use state).

  About the length of the 1st support | pillar 12 and the 2nd support | pillar 14, since it exists in the relationship of 1st support | pillar 12> 2nd support | pillar 14, the height in each use condition is 1st use condition> The relationship is second usage state> third usage state> fourth usage state.

Next, the storage time of the electric fan 100 will be described with reference to FIG. When the electric fan 100 according to the present invention is stored, the connector cover 24 is removed from the storage part 20c of the electric motor case 20, and the support part of the base 10 is placed so that the fan 50 and the front and rear fan guards 16 and 18 for storing the fan 50 face upward. The storage part 20c of the electric motor case 20 is inserted and connected to the tip of 10b.

  Since the connector cover 24 is provided with the finger pressing portion 24a (see FIG. 9), it can be easily removed. The removed connector cover 24 is attached to the case connecting portion 20b to which the support column is connected when the electric fan is stored. By doing so, the engaging pins 33a and 33b of the case connecting portion 20b are not exposed but are protected by the connector cover 24, so that the connecting portion of the case connecting portion 20b can be protected from dust and moisture. This makes it possible to reduce the probability of malfunctions such as malfunctions. FIG. 16 shows the inside of the connector cover 24, and engagement pin receiving holes 24b1 and 24b2 are provided. Further, since the sizes of the engagement pin receiving holes 24b1 and 24b2 are different according to the difference in the outer diameters of the engagement pins 33a and 33b, when attaching the connector cover 24 to the case connecting portion 20b, You need to be careful.

  17 and 18 show a deformed connector cover 25 for facilitating smooth engagement of the engaging pins 33a and 33b. Specifically, two U-shaped recesses 25c are provided on the cylindrical outer periphery, and two engagement pin receiving portions 25b are provided on the bottom side of the recesses 25c. Therefore, the positional relationship into which the engagement pins 33a and 33b are inserted can be confirmed, and a direction error at the time of attachment can be eliminated.

    At this time, the first support column 12 and the second support column 14 are accommodated in a horizontally placed state in a space generated in the rear surface portion of the motor case 20 and the upper surface portion of the base 10 in a disassembled state.

  By storing in this way, it becomes possible to suppress the height to be lower than that of a fan having a structure in which a conventional support can be expanded and contracted. Further, if the diameter of the pedestal 10 and the diameter of the fan guard are substantially the same, since the fan is stored in a shape close to a cylinder, the useless space in the storage space is reduced as compared with the conventional one.

  Note that the present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the scope of the present invention.
