(First embodiment)
1st Embodiment of the vacuum cleaner which concerns on this invention is described based on FIG.

  The vacuum cleaner of 1st Embodiment is comprised from the main-body part 1 provided with the dust collection part and electric blower which are not shown in figure, and the support | pillar part 2 with which the main-body part 1 is detachably mounted | worn (FIG. 1, FIG. 2).

  At both ends of the back surface of the main body 1 in the front-rear direction (vertical direction in FIG. 1), mounting portions 3 for mounting on the support column 2 are formed. On one side surface of the main body 1, a handle 4 is formed which is used when carrying the main body 1 removed from the support column 2. A main body side switch 5 for operating an electric blower (not shown) is disposed in the vicinity of the handle 4. A first suction port 7 that communicates with a dust collection unit (not shown) through a hose 6 is detachably communicated with an opening 8 formed in the support column 2. When the main body 1 is mounted on the support 2, the receiver 1 that receives a radio signal from the support 2 is provided in the main body 1 at a position facing the support 2. A control board (not shown) that drives and controls an electric blower (not shown) based on the operation of the main body side switch 5 and a signal received by the receiving unit 9 is provided in the main body 1. A power cord 10 is connected to the main body 1 so that the main body 1 can be used alone by operating the main body side switch 5 (see FIG. 3).

  The support column 2 includes a base portion 12 having a second suction port 11, and an operation portion 14 that is rotatably connected via the base portion 12 and a rotation portion 13. The base portion 12 is formed with a mounted portion 15 with which the mounting portion 3 of the main body portion 1 is engaged. By attaching the first suction port 7 of the main body 1 to the opening 8 of the base portion 12, the second suction port 11 and the dust collecting unit (not shown) are connected via the first suction port 7 and the hose 6. Communicate.

  A grip 16 that is gripped when operated by the user is formed at an end of the operation unit 14 that is rotatably connected to the base unit 12 via the rotation unit 13 and that faces the rotation unit 13. . In the vicinity of the grip 16, a column-side switch 17 for remotely operating an electric blower (not shown) of the main body 1 is disposed. The operation unit 14 is provided with a transmitter 18 that wirelessly transmits a signal from the column-side switch 17 to the receiver 9. A hook 19 that is operated when the operation unit 14 is folded so as to be substantially parallel to the base unit 12 when the electric vacuum cleaner is housed is disposed in the operation unit 14 in the vicinity of the rotation unit 13.

  The vacuum cleaner configured as described above engages the mounting portion 3 of the main body portion 1 with the mounted portion 15 of the column portion 2, and connects the first suction port 7 of the main body portion 1 to the opening portion 8 of the column portion 2. It can be used as an upright type vacuum cleaner by attaching to (see FIG. 1). And if a user grasps the grip 16 of the support | pillar part 2 and operates the support | pillar part side switch 17, the dust suck | inhaled from the 2nd suction inlet 11 of the support | pillar part 2 by the drive of an electric blower will become the 1st suction inlet 7 and The dust is collected by a dust collecting unit (not shown) of the main body 1 through the hose 6.

  When cleaning a place with a step such as stairs or high places, hold the handle 4 of the main body 1 and remove the main body 1 from the support 2 and hold the main body 1 and the support 2 with both hands. By doing so, since the support | pillar part 2 which has the 2nd suction inlet 11 can be lightened and lifted easily, it can clean easily also in the place with steps, such as stairs, or a high place (refer FIG. 2).

  When cleaning a narrow space such as a gap in the chest, hold the handle 4 of the main body 1 and remove the main body 1 from the support 2 and remove the first suction port 7 from the opening 8 of the support 2. The gap suction tool 20 is attached to the first suction port 7 and used alone (see FIG. 3).

When using as an upright type vacuum cleaner as shown in FIG. 1 or when using the main body 1 and the support column 2 in both hands as shown in FIG. 2, the second suction port 11 is placed under the bed. When placing and cleaning the deep part under the bed, the hose 6 touches the corner of the bed and the first suction port 7 is detached from the opening 8, and the first suction port 7 is detached from the opening 8. There is a possibility that an important object is sucked into the main body 1 from the first suction port 7 until it is noticed. In the first embodiment, by providing a detection means for detecting that the first suction port 7 is attached to the opening 8, it is possible to prevent the occurrence of the inconvenience as described above. .

  A switch for driving an electric blower (not shown) is provided on the main body 1 and the support 2 in order to improve usability. However, the following problems may occur if the electric blower is driven unconditionally on the basis of the operation signals of the switches disposed on the main body 1 and the support column 2 regardless of the above-described usage. There is.

  For example, when the main body unit 1 is used alone as shown in FIG. 3, a person other than the user can use a post unit side switch 17 located away from the main body unit 1 against the intention of the main body user. If you make a mistake, switch from weak driving to strong driving, and inhale important things in the vicinity of the place you are cleaning into the main unit 1 or be surprised at the action against your intention. There is a possibility that problems such as causing the user to panic and damage the equipment.

  Therefore, in the first embodiment, as shown in FIG. 4 or FIG. 5, detection means for detecting whether or not the main body 1 is mounted on the support column 2 is provided. A magnet 21 is mounted on the inner surface of the mounted portion 15 of the support column 2. A reed switch 22 that is actuated by the magnetic force of the magnet 21 is mounted on the inner surface of the mounting portion 3 of the main body 1 that faces the magnet 21. When the reed switch 22 is close to the magnet 21, the reed switch 22 is turned on, and when the reed switch 22 is separated from the magnet 21, the reed switch 22 is turned off. Accordingly, the positional relationship between the main body 1 and the support column 2 can be estimated by detecting the ON / OFF signal of the reed switch 22.

  When the reed switch 22 is ON, as shown in FIG. 1, the main body 1 is in the state of being attached to the support 2, so that the electric blower (not shown) of the main body 1 is connected by the support 17. Even if it is driven, the above-mentioned problem does not occur. Therefore, the main body 1 receives the operation signal transmitted to the main body 1 through the transmitting section 18 and the receiving section 9 and drives the electric blower simply by grasping the grip 16 and operating the support section side switch 17. It can be used as an upright type vacuum cleaner with improved operability. Moreover, since the support | pillar part side switch 17 is located in the vicinity of the grip 16, operativity improves. Further, since the signal from the column-side switch 17 can be transmitted wirelessly to the main body unit 1, it is not necessary to electrically connect the column unit 2 and the main body unit 1, and the configuration can be simplified. it can. At this time, it can be used not only from the column-side switch 17 but also by operating the body-side switch 5.

  When the reed switch 22 is OFF, the main body 1 is not attached to the support 2 as shown in FIGS. When the electric blower is driven, a vacuum cleaner that operates against the user's intention causes the main body 1 to inhale important things in the vicinity of the place being cleaned, or against the intention. There is a risk that a user who is surprised at the action will be panicked and damage the equipment. Therefore, when the main body 1 is not mounted on the support 2, the main body 1 does not receive the signal even if the support 17 is operated. As a result, the above-described problem can be solved. At this time, the electric blower can be driven by the main body side switch 5.

  In this way, the vacuum cleaner can be operated with the main body side switch 5 or the column side switch 17 as necessary, so that the usability is improved.

(Second Embodiment)
6 or 7 shows a second embodiment of the vacuum cleaner according to the present invention. In addition, about the same component as 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. Even if the main body 1 is removed from the support 2, if the main body 1 is positioned in the vicinity of the support 2, the situation can be recognized even if the support 17 is operated. Even if the main body 1 is removed from the support 2, if the main body 1 is located in the vicinity of the support 2, a problem arises even if the same electric blower control as in the first embodiment is performed. No In the second embodiment, the main body 1 is attached to the support 2 or the main body 1 is separated from the support 2 but the main body 1 is located in the vicinity of the support 2 IC tag reader 24 that reads information from IC tag 23 is attached to the inner surface of mounting portion 3 of main body 1 that faces IC tag 23 and IC tag 23 on the inner surface of mounted portion 15 of support column 2. Yes.

  When the IC tag 23 is close to the IC tag reader 24, the IC tag reader 24 can read the information of the IC tag 23, and when the IC tag 23 is separated from the IC tag reader 24, the IC tag reader 24 can read the information of the IC tag 23. Cannot be read. Therefore, the positional relationship between the main body 1 and the support column 2 can be estimated based on whether or not the IC tag reader 24 can read the information of the IC tag 23.

  Since the IC tag reader 24 can read the information of the IC tag 23 in any direction as long as the radio wave reaches, when the main body 1 is located in the vicinity of the column 2, By setting the IC tag 23 and the IC tag reader 24 so that the IC tag reader 24 can read the information of the IC tag 23, it can be estimated that the main body 1 is located in the vicinity of the support column 2.

  When the IC tag reader 24 can read the information of the IC tag 23, as shown in FIG. 1, the main body 1 is mounted on the column 2 or the main unit 1 is separated from the column 2 However, since the main body 1 is located in the vicinity of the column 2, even if the electric blower (not shown) of the main unit 1 is driven by the column-side switch 17, there is a problem as described in the first embodiment. Does not occur. Therefore, since it can be used as an upright type vacuum cleaner simply by gripping the grip 16 and operating the column-side switch 17, the operability can be improved. At this time, it can be used by operating the main body side switch 5 as in the first embodiment.

  When the IC tag reader 24 cannot read the information of the IC tag 23, the main body 1 is not attached to the support 2 as shown in FIG. 2 and FIG. Since the electric blower (not shown) of the main body unit 1 is driven by the support unit side switch 17 because it is sufficiently separated, the electric vacuum cleaner that operates against the intention of the user is used for cleaning. There is a possibility that problems such as inhaling important things in the vicinity into the main body 1 or causing the user to be surprised by an unintentional operation and damaging the equipment. Therefore, when the main body 1 is not attached to the support 2 and the main body 1 is sufficiently separated from the support 2, the signal is transmitted even if the support 17 is operated. The above-described problem can be solved by adopting a configuration that does not accept. At this time, the electric blower can be driven by the main body side switch 5.

(Third embodiment)
FIG. 8 or FIG. 9 shows a third embodiment of the electric vacuum cleaner according to the present invention. In addition, about the same component as 1st Embodiment or 2nd Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  A contact point 26 a that is electrically connected to the column-side switch 17 via the column-side power supply line 25 is disposed on the mounted portion 15 of the column unit 2. The distal end portion 27 of the contact 26 a protrudes toward the mounting portion 3 side of the main body portion 1. A contact 26 b that is electrically connected to an electric blower (not shown) of the main body 1 via the main body side power supply line 28 is disposed on the mounting portion 3 of the main body 1. The contact 26 b is biased toward the mounted portion 15 side of the support column 2 by a spring 29. A hole 30 having a diameter larger than that of the contact 26 a is formed in the mounting portion 3 of the main body 1, and the contact 26 a and the contact 26 b can be contacted through the hole 30.

  When the main body 1 is mounted on the support 2, the tip 27 of the contact 26 a disposed on the mounted portion 15 of the support 2 and the contact 26 b disposed on the mounting 3 of the main body 1 are not matched. Touch. As a result, the column-side switch 17 and the electric blower (not shown) of the main body 1 are electrically connected. In the state where the main body 1 is mounted on the support 2, no problem occurs even if the electric blower (not shown) of the main body 1 is driven by the support 17 on the support. Therefore, it can be used as an upright type vacuum cleaner simply by gripping the grip 16 and operating the column-side switch 17, and the operability can be improved.

  When the main body 1 is removed from the support 2, the tip 27 and the contact 26 b of the contact 26 a are not in contact with each other, so that the electrical connection between the support 17 and the electric blower (not shown) of the main body 1 is interrupted. The As a result, the electric blower is not driven even if the support unit side switch 17 is operated. Therefore, a user who was surprised at the action against the user's intention, such as sucking important things in the vicinity of the place to be cleaned into the main body 1 by a vacuum cleaner that operates against the user's intention. There is no risk of problems such as damaging behavior and damaging equipment. When the electric blower is driven, the main body side switch 5 may be operated.

(Fourth embodiment)

In addition, about the same component as 1st Embodiment thru | or 3rd Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. 4th Embodiment has shown another form in the case of cleaning a place with steps, such as a staircase, or a high place in 1st Embodiment thru | or 3rd Embodiment.

  In the fourth embodiment, the first flow path 31 communicating with the second suction port 11 is formed in the base portion 12 of the support column 2, and the first flow channel 31 can be connected in the operation unit 14 of the support column 2. A second flow path 32 is formed. The base portion 12 and the operation portion 14 of the support column 2 are rotatable by the rotation portion 13, and when the operation portion 14 is rotated and bent toward the base portion 12 side, the first flow path 31 and the first operation portion 14 are rotated. It does not communicate with the two flow paths 32 (see FIG. 11). When the operation part 14 is extended in a substantially straight line with the base part 12, the first flow path 31 and the second flow path 32 communicate with each other (see FIGS. 10 and 12). In the vicinity of the grip 16, an insertion port 33 through which the second flow path 32 communicates with the outside air is formed (see FIG. 10). The first suction port 7 of the main body 1 can be detachably attached to the insertion port 33.

A joint member 34 made of rubber or resin and having excellent elasticity and wear resistance is fixed to the connection portion of the first flow channel 31 with the second flow channel 32. From the state where the first flow path 31 and the second flow path 32 are not in communication, that is, the state where the operation portion 14 is bent toward the base portion 12 (see FIG. 11), the first flow path 31 and the second flow path 32, that is, when the operation portion 14 is extended in a substantially straight line with the base portion 12 (see FIG. 12), the joint between the first flow path 31 and the second flow path 32 is a joint member. Therefore, airtightness between the first flow path 31 and the second flow path 32 is maintained.

  The vacuum cleaner according to the fourth embodiment configured as described above is operated by holding the main body 1 and the column 2 with both hands when cleaning a place with a step such as a staircase or a high place. Since the insertion port 33 into which the first suction port 7 of the main body 1 is inserted is in the vicinity of the grip 16, the hose 6 can be used even when the second suction port 11 is placed under the bed and the deep part under the bed is cleaned. Can be prevented from being rubbed and damaged by the corners under the bed, and the first suction port 7 can be prevented from being detached from the support column 2. Moreover, since the hose 6 can be attached and detached without bending the body, the operability is improved. Furthermore, since the support | pillar part 2 in which the 2nd flow path 32 was formed is made to fold by the rotation part 13, when it is not using, it becomes compact and storage property improves.

  FIG. 13 shows a modification of the fourth embodiment. The insertion port 33a is formed on the upper side surface of the second flow path 32, and the first suction port 7 can be detachably attached to the insertion port 33a. I have to. Even in such a configuration, even when the second suction port 11 is placed under the bed and a deep place under the bed is cleaned, the hose 6 is prevented from being scratched or damaged by the corner under the bed. In addition, it is possible to prevent the first suction port 7 from being detached from the support column 2.

  15 to 19 show modified examples of the connection portion between the first flow path 31 and the second flow path 32. The second flow path 32 is configured to be slidable up and down, and when the operation section 14 is bent, the second flow path 32 is slid upward to prevent contact with the first flow path 31 (see FIG. 14) and the operation section. When 14 is extended, the second flow path 32 is slid downward and fitted into the first flow path 31 (see FIGS. 15 and 16). As a result, it is not necessary to use another member, and the configuration can be simplified.

  If the first flow path 31 and the second flow path 32 are not in communication with each other, that is, if the operation portion 14 is left folded for a long time in the base portion 12 side, the first flow path 31 and the second flow path 32 are left. There is a risk that dust accumulates inside. In the fourth embodiment, the first flow path 31 is formed by covering the first flow path 31 and the second flow path 32 opened upward by bending the operation section 14 toward the base section 12 with the cover 35 as an accessory. Further, dust is prevented from accumulating in the second flow path 32 (see FIG. 17).

(Fifth embodiment)
18 to 21 show a fifth embodiment of the electric vacuum cleaner according to the present invention. In addition, about the same component as 1st Embodiment thru | or 4th Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. 5th Embodiment has shown another form with respect to another form in the case of cleaning the place with steps, such as the staircase of 4th Embodiment, or a high place.

  The vacuum cleaner according to the fifth embodiment supplies the air sucked from the second suction port 11 to the main body 1 through the first suction port 7, and the exhaust gas removed from the dust by the dust collecting unit (not shown) of the main body 1. A part is exhausted from the main body 1, and the remaining exhaust is circulated to the second suction port 11. Therefore, two types of air flow paths are formed for intake and circulation exhaust. The inside of the base portion 12 of the support column 2 has a double structure including an inner pipe 36 and an outer pipe 37, and the space between the inner pipe 36 and the outer pipe 37 is an intake passage 38 inside the inner pipe 36. Is a circulation exhaust passage 39. A circulation exhaust passage 39 of the base portion 12 and a circulation exhaust passage (not shown) of the main body portion 1 communicate with each other via a circulation exhaust port 40 (see FIG. 18). Further, the inner pipe 36 is configured to be detachable from the base portion 12.

When the vacuum cleaner of the fifth embodiment configured as described above is used to clean a place with a step such as a staircase or a high place, the main body 1 is removed from the support 2 and the inner pipe 36 is attached to the base. 12 (see FIG. 19). The joint tool 41 is attached to one end of the inner pipe 36 taken out from the base portion 12, and the gap suction tool 20 is attached to the other end of the inner pipe 36 (see FIG. 20). Then, the joint tool 41 is connected to the outer pipe 37 (see FIG. 21), and the circulation exhaust port 40 is closed by a closing means (not shown).

  By doing so, the distance from the grip 16 to the gap suction tool 20 can be increased, so that the grip 16 can be gripped and cleaned to a narrower or higher place with a greater depth, which improves usability. . At this time, the function of exhaust circulation is lost, but there is no problem in the suction performance, and it can be used without any problem in function. In addition, although the suction tool 20 for gap | intervals was mounted | worn with the inner side pipe 36, you may mount | wear with another suction tool.

(Sixth embodiment)
22 to 26 show a sixth embodiment of the vacuum cleaner according to the present invention. In addition, about the same component as 1st Embodiment thru | or 5th Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. 6th Embodiment has shown the form of the dust collection part 42 of a cyclone type vacuum cleaner.

  The exhaust gas containing the dust sucked into the main body 1 is sucked into the cyclone type dust collecting part 42 through the suction port 43. Exhaust gas sucked into the dust collecting part 42 is separated into large dust while swirling in the outer cyclone flow path 44, and the separated large garbage is deposited on the bottom of the dust collecting part 42, and large dust is separated. The exhausted air is sucked into the inner cyclone channel 45. The exhaust sucked into the inner cyclone flow path 45 is separated from small dust while swirling the inner cyclone flow path 45, and the separated small dust is deposited on the bottom of the dust collecting portion 42, and the small dust is separated. When the exhausted gas passes through the filter 47 attached to the cylindrical portion 46 located at the center of the inner cyclone channel 45, fine dust is removed and exhausted to the outside.

  When maintaining the dust collecting part 42, the lid 48 of the dust collecting part 42 is removed to discard the dust deposited on the bottom of the dust collecting part 42 and remove the dust adhering to the filter 47. Conventional filters have been insert-molded into a cylindrical portion located at the center of the cyclone flow path. As a result, the filter could not be easily taken out, and it was difficult to clean the conventional filter.

  On the other hand, the filter 47 of the sixth embodiment facilitates maintenance because it is configured to be detachably mounted from the cylindrical portion 46 of the dust collecting portion 42. A plurality of holes 49 are formed in the cylindrical portion 46 located at the center of the inner cyclone channel 45. The filter 47 is formed by insert-molding a mesh part 51 for dust removal into a rectangular soft frame 50 and is provided with locking means 52 such as velcro tape at both ends of the opposite sides of the long side of the frame 50.
