Description

  The present invention relates to a vacuum cleaner, and more specifically to a handheld vacuum cleaner.

  2. Description of the Related Art Conventionally, a technique of blowing hot air from a vacuum cleaner to a surface to be cleaned is known in order to remove pests such as mites attached to a futon, a carpet, a sofa, and the like. Such techniques are disclosed in Patent Documents 1 to 4, for example.

  In Patent Document 1, an electric heater and a blower fan are attached to the periphery of the suction opening of the head member of the vacuum cleaner, and air heated by the electric heater is sent from the blowout port to the futon and carpet by the blower fan. Technology that kills harmful insects and microorganisms with hot air and sucks the dead bodies from the suction opening of the head is disclosed.

  Patent Document 2 discloses a pest control device, although it is not a vacuum cleaner. This pest control device includes a cover capable of covering a part of the floor surface, a blower for sucking air in the cover from the suction port and blowing it out from the blowout port, and a suction port. A dust collector for cleaning the air reaching the air outlet and a heater for heating the air blown from the air outlet are provided.

  Patent Document 3 discloses a technique for discharging high-temperature exhaust of an electric blower from an exhaust hose fitted in an exhaust port of a vacuum cleaner into a sealed, non-breathable futon drying bag to kill pests. Yes.

  Patent Document 4 discloses a handy vacuum cleaner. In this handy type vacuum cleaner, a suction port that directly faces the surface to be cleaned is provided on the lower surface of the cleaner body. In the vacuum cleaner main body, a dust collecting chamber having a built-in dust collecting filter and an electric blower are provided so that the suction side communicates with the dust collecting chamber. The vacuum cleaner main body is provided with a reflux air passage that allows the exhaust side of the electric blower to communicate with the suction port. Moreover, the lower surface of the vacuum cleaner main body is provided with a slit-like exhaust port that communicates the exhaust side of the vacuum cleaner with the reflux air passage. The return air passage has a notch formed in a portion facing the exhaust port, and a switching opening / closing plate for selectively opening and closing the notch is provided. In the handy type vacuum cleaner of Patent Document 4, dust is sucked in together with air from the suction port by the driving of the electric blower, and is captured by the dust collecting filter in the dust collecting chamber. The air that has passed through the dust collection filter is sucked into the electric blower. The exhaust air from the electric blower passes through the exhaust port.

  When the cutout portion is closed by the switching opening / closing plate, the exhaust air from the electric blower is not discharged to the outside, returns to the suction port through the return air passage, and is blown to the surface to be cleaned. Then, a part of the exhaust air is sucked again into the dust collecting chamber and the electric blower, and as a result, a recirculation airflow that repeatedly goes around the suction port, the dust collecting chamber, the electric blower, and the return air passage is generated in the cleaner body. And the temperature of a circulating air flow rises when air repeatedly passes through the electric blower which generates heat. The exhaust air thus heated is blown from the return air passage to the surface to be cleaned through the suction port, so that the insects on the surface to be cleaned are sucked out and captured in the dust collection chamber.

  Patent Documents 5 and 6 disclose handy-type vacuum cleaners for cleaning futons and the like.

Patent Document 5 mainly discloses an electric layer cleaner provided with a sterilizer provided with an ultraviolet lamp.

  Further, Patent Document 6 mainly describes a dust hitting that strikes the object to be cleaned and removes the foreign object from the object to be cleaned, and a cylindrical shape that is attached to the main body of the cleaner so as to rotate and separates the object from the object to be cleaned. A vacuum cleaner with a brush is disclosed. In the electric vacuum cleaner disclosed in Patent Document 6, the driving source that provides the driving force for operating the dust hitting and the cylindrical brush is single.

  Patent Documents 7 to 9 disclose rotating brushes used in electric vacuum cleaners.

Yes. Moreover, a futon is assumed as a main cleaning object of the electric vacuum cleaner 1. The dust sucked from the futon has a lot of fine powder as compared to the dust sucked from the flooring or the carpet. For this reason, the dust sucked from the futon is accumulated in the dust collector 200 at an angle inclined with respect to the axis of the dust collection cup 210. Therefore, as shown in FIG. 11, the “trash full” line indicating the garbage accumulation for the user is displayed on the outer surface of the dust collection cup 210. The “dust full” line is preferably displayed at an angle inclined with respect to the axis P of the dust collection cup 210.

(Operation of electric vacuum cleaner 1)
Operation | movement of the vacuum cleaner 1 which concerns on this embodiment is demonstrated below. First, when a user cleans an object to be cleaned such as a futon using the electric vacuum cleaner 1, the user holds the operation handle 300 and supports the cleaner main body 100 by hand. Then, the bottom surface of the vacuum cleaner main body 100 is grounded to the object to be cleaned, and the opening 21a of the suction unit 20 and the external discharge port 3 are brought close to and opposed to the object to be cleaned. When the electric vacuum cleaner 1 is operated, the main body circuit board 8 (control device) provided in the cleaner main body 100 operates the electric blower 61 and the rotating brush drive motor 14 of the rotating brush 4.

  When the rotating brush drive motor 14 is driven, the rotating brush 4 rotates. And by rotation of the rotating brush 4, pests, such as dust or a tick, which are present on the surface of the cleaning object such as a futon are scraped.

  Here, as shown in FIG. 12, the rotary brush drive motor 14 is located in front of the rotary brush 4 and is disposed at a distance from the electric blower 61 located behind the rotary brush 4. Thereby, the heat generated from the electric blower 61 is hardly transmitted to the rotary brush drive motor 14, and the rotary brush drive motor 14 can be operated more safely.

  When the electric blower 61 is operated, dust-containing air is sucked from the opening 21a. The dust-containing air sucked from the opening 21a flows into the dust collector 200 from the inlet 210a through the nozzle pipe 5 via the separation flow path Y indicated by the arrow in FIG. It passes through and is discharged from the dust collector 200. The air discharged from the dust collector 200 is sucked into the electric blower unit 60 in which the electric blower 61 is accommodated.

  In the dust collector 200, the upper part acts as a centrifugal separator 240 with the flange part 212 a at the upper part of the dust partition part 212 in the dust collecting cup 210 as a boundary. That is, in the dust collector 200, the centrifugal separator 240 is a swirling air path constituted by the inner surface of the dust collection cup 210, the outer peripheral surface of the inner cylinder portion 211, and the like. And the inflow port 210a is opened in the tangential direction of the turning air path which the centrifuge part 40 comprises. Therefore, the dust-containing air that has flowed in through the inlet 210a is swirled in the swirl air passage formed by the centrifugal separator 240 as in the separation channel Y of FIG. Is centrifuged. Of the dust that has been centrifuged, relatively large coarse dust (first dust) falls along the inner surface of the dust collection cup 210 due to the action of centrifugal force, and is accumulated below the dust partition portion 212. The

  The air from which the coarse dust has been separated passes through the inner cylindrical portion 211 (see the separation flow path Y in FIG. 5). At this time, the relatively small fine dust (second dust) that has not been separated by the centrifugal separator 240 rises through the slit 211b of the inner cylinder portion 211 together with the air flow. On the other hand, the coarse dust is filtered by a mesh filter wound around the body 211c. The air that has passed through the inner cylinder portion 211 passes through the filter unit housed in the upper lid unit 220 to remove fine dust (second dust) and is discharged from the dust collector 200. The dust collector 200 is a dust collector of a type that collects dust in a swirling air passage (cyclone). However, the dust collector 200 is not limited to a cyclone type dust collector, and may be a paper pack type or cloth bag type dust collector.

  The air discharged from the dust collector 200 is sucked into the electric blower unit 60. The air discharged from the dust collector 200 passes through the ventilation passage 61c of the electric blower 61 generating heat in the electric blower unit 60, and passes through the exhaust duct 61b formed on the side surface of the exhaust duct member 68. A flow path that bypasses the side wall of the electric blower housing 68a is taken. Then, it passes through the exhaust filter 7 and is discharged from the electric blower unit 60 (see the flow path Z1 in FIG. 5). At this time, the air passes through the ventilation passage 61c of the electric blower 61 generating heat. As a result, the air is heated and becomes warm air and is discharged from the electric blower unit 60. And the warm air discharged | emitted from the electric blower unit 60 passes the exhaust filter 7, and is discharged | emitted outside from the external discharge port 3 formed in the bottom face of the cleaner body 100. FIG.

  Here, the circuit board housing portion 68b of the electric blower unit 60 communicates with the electric blower housing portion 68a via the upstream vent 68d and the downstream vent 68e. For this reason, a part of the air discharged from the exhaust port 61b of the electric blower 61 flows into the circuit board housing portion 68b through the upstream vent 68d, and along the flow path Z2 defined by the guide rib 68f. Then, it passes through the circuit board housing portion 68b and flows out to the electric blower housing portion 68a through the downstream side vent 68e. And the air which flowed out to the electric blower accommodating part 68a via the downstream vent 68e passes the exhaust filter 7, and is discharged | emitted outside from the external discharge port 3 formed in the bottom face of the cleaner body 100. FIG.

As described above, in the vacuum cleaner 1, the warm air flow path Z1 heated by the electric blower 61 is branched into a flow path Z2 in which a part of the warm air passes through the circuit board housing portion 68b. . The flow path Z2 passing through the inside of the circuit board housing part 68b is used for cooling the main circuit board 8 housed in the circuit board housing part 68b. During operation of the vacuum cleaner 1, the temperature of the main circuit board 8 is about 10
0 ° C or higher. On the other hand, the temperature of the warm air heated by the electric blower 61 is about 60 ° C to 70 ° C. Therefore, the main circuit board 8 is cooled by the hot air heated by the electric blower 61.

  Further, the flow path Z2 passing through the inside of the circuit board housing portion 68b joins the flow path Z1 again on the upstream side of the exhaust filter 7. The flow path Z1 and the flow path Z2 pass through the single exhaust filter 7. The air in the flow path Z1 and the flow path Z2 is cleaned by the exhaust filter 7, and is discharged from the external discharge port 3 to the outside.

  In the vacuum cleaner 1 that applies hot air to the object to be cleaned using the exhaust heat of the electric blower 61, an exhaust filter 7 is mounted to purify the air discharged to the outside. Further, since the vacuum cleaner 1 is equipped with a control device such as the main body circuit board 8, the hot air heated by the electric blower 61 is supplied to the circuit board housing portion 68b for cooling the main body circuit board 8. It is necessary to make it flow.

  Here, as a flow path configuration for cooling the main circuit board 8, all the warm air heated by the electric blower 61 is caused to flow into the circuit board housing portion 68b, and the air discharged from the circuit board housing portion 68b is exhausted. A flow path configuration that allows passage through the filter 7 is conceivable. However, in this flow path configuration, the amount and temperature of the air discharged from the external discharge port 3 may decrease due to the reason that the warm air heated by the electric blower 61 stays in the circuit board housing portion 68b. There is. As a result, a sufficient thermal effect due to the air discharged from the external discharge port 3 cannot be obtained.

  On the other hand, in the vacuum cleaner 1 according to the present embodiment, a part of the air passing through the ventilation passage 61c of the electric blower 61 flows into the circuit board housing portion 68b via the upstream vent 68d, The remaining portion has a flow path configuration that does not flow into the circuit board housing portion 68b. Therefore, the amount of air discharged from the external discharge port 3 can be maintained. Therefore, a sufficient thermal effect by the air discharged from the external discharge port 3 can be obtained, and the main circuit board 8 can be sufficiently cooled.

  When a user cleans an object to be cleaned such as a futon using the electric vacuum cleaner 1, the user grounds the bottom surface of the vacuum cleaner main body 100 to the object to be cleaned such as a futon and sets the opening 21 a and the external outlet 3 to be cleaned. The cleaner body 100 is moved in the direction of the arrow X shown in FIG.

  When the user cleans, first, warm air is blown to the object to be cleaned through the external outlet 3. Thus, the cleaning target object is heated by blowing the exhaust air warm air from the electric blower 61 onto the cleaning target object such as a futon. Then, for example, tentacles such as mites clinging to the duvet cotton are separated from the duvet cotton, and the pests are weakened. The thus weakened pest is sucked into the cleaner body 100 from the opening 21a.

  Thus, in the vacuum cleaner 1, when passing through the electric blower 61, it is heated by the exhaust heat (exactly, the exhaust heat of the drive motor) and is discharged from the external outlet 3 as warm air ( exhaust). Thus, by using the exhaust heat of the electric blower 61, the exhaust can be heated without providing a heater separately, and the configuration of the vacuum cleaner 1 can be simplified and the power consumption can be suppressed. it can.

  Here, in the vacuum cleaner 1 which concerns on this embodiment, the rotating brush 4 is accommodated in the suction unit 20 which has the opening part 21a (suction opening). In the suction unit 20, the rotary brush 4 is provided so as to be exposed from the opening 21a. In other words, the rotating brush 4 is provided between the opening 21a and the external discharge port 3, and is disposed in the vicinity of the opening 21a.

  Thereby, in the vacuum cleaner 1, the operation | movement which scrapes off insects, such as dust or a tick, from the surface of cleaning objects, such as a futon, and the suction operation with the rotating brush 4 is performed in the vicinity of the opening 21a of the suction unit 20. Therefore, the pest weakened by the warm air can be efficiently sucked into the cleaner body 100.

  In addition, the moving direction of the cleaner body 100 is not limited to the direction of the arrow X, and the direction opposite to the arrow X is also possible. It is also possible to clean the cleaner body 100 by reciprocating it. In this case, when the cleaner body 100 is moved in the direction opposite to the arrow X direction, there is an effect that the moisture of the cleaning object such as the futon can be removed by the warm air from the external discharge port 3. In addition, there is an effect that dust or the like can be collected by suction from the opening 21a by the rotation of the rotating brush 4. In addition, by blowing the exhaust of warm air heated by the electric blower 61, moisture contained in the cleaning object such as the futon is removed, and the cleaning object such as the futon can be swollen. . Such an effect is exhibited regardless of the moving direction of the cleaner body 100.

  Moreover, in the vacuum cleaner 1, the partition wall 21c which partitions off between the opening part 21a as a suction inlet and the external discharge port 3 is provided in the bottom face of the lower base | substrate 122 of the vacuum cleaner main body 100. As shown in FIG. The partition wall 21c can prevent the warm air discharged from the external discharge port 3 from being sucked into the opening 21a. Therefore, excessive circulation of exhaust air between the opening 21a (suction port) and the external discharge port 3 in the vacuum cleaner main body 100 can be prevented, and excessive temperature rise of the vacuum cleaner main body 100 due to exhaust circulation. Can be prevented. As a result, the safety and reliability of the vacuum cleaner 1 can be improved.

  Moreover, since the roller 16 is accommodated in the roller accommodating part 21d of the suction unit 20, the movement of the vacuum cleaner 1 becomes easy and operativity improves.

  The partition wall 21 c is provided on the bottom surface of the lower base 122, but may be provided on the brush housing 21 side of the suction unit 20. In this case, the partition wall 21 c is configured integrally with the brush housing 21. More specifically, a part of the side wall constituting the roller accommodating portion 21d is constituted by the partition wall 21c described above.

  Thus, since the roller 16 is accommodated in the roller accommodating part 21d which makes the partition wall 21c a part of side wall, the movement of the vacuum cleaner 1 becomes easy and operativity improves.

  13 shows a modification of the electric vacuum cleaner 1 shown in FIG. 1, (a) of FIG. 13 is a side view, (b) of FIG. 13 is a bottom view, and (c) of FIG. FIG. 3 is a front view seen from the front side. As shown in (a) to (c) of FIG. 13, the vacuum cleaner 1 a is provided with a rib 21 e for preventing the body from falling forward from the brush housing 21 toward the front. The forward-falling prevention rib 21e is a plate or box structure, and extends in a direction substantially parallel to the surface of the object to be cleaned.

  Thereby, when the user lifts the cleaner main body 100 via the operation handle 300 and pushes it from the rear, it is possible to prevent the cleaner main body 100 from being in a forward posture. Therefore, it is possible to prevent an excessive force from being required when the cleaner body 100 is moved.

[Embodiment 2]
The following will describe another embodiment of the present invention with reference to FIGS. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

  The vacuum cleaner according to the present embodiment is different from the first embodiment in the configuration of the rotating brush 4. FIG. 14 shows a configuration of the rotating brush 4 of the electric vacuum cleaner according to the present embodiment, FIG. 14 (a) is a side view, and FIG. 14 (b) is a perspective view. Moreover, (a) of FIG. 15 is sectional drawing which shows an example of a structure of the rotating brush 4 of the vacuum cleaner which concerns on this embodiment, (b) of FIG. 15 has a different structure from (a) of FIG. It is sectional drawing which shows the rotating brush 4 which has, and FIG.15 (c) is sectional drawing which shows the rotating brush 4 which has a different structure from (a) and (b) of FIG. FIG. 16 is a side view showing the configuration of the tapping member 4b1 shown in FIG. 15B when it is removed from the brush base 4d.

  As shown in FIGS. 14A and 14B, the rotary brush 4 includes a rotary shaft portion 4a, a hitting member 4b, and a brush member 4c. The hitting member 4b and the brush member 4c are provided so as to cover the rotation shaft portion 4a, and extend spirally in the rotation direction of the rotation shaft portion 4a. As shown in FIGS. 15A and 15C, the rotating shaft portion 4a is provided with a brush base portion 4d serving as an installation portion for the hitting member 4b and the brush member 4c. A plurality of protrusions 4e are formed on the brush base portion 4d so as to extend in the direction of the rotation shaft portion 4a. The brush member 4c is inserted between two adjacent protrusions 4e.

  The hitting member 4b includes an insertion portion 4f inserted between two adjacent protrusions 4e, and a hitting portion main body 4g connected to the insertion portion 4f. The hitting portion main body 4g protrudes beyond the protrusion 4e of the brush base portion 4d. The hitting member 4b is made of a material that is more flexible than the brush member 4c, for example, a rubber material.

  As the rotary brush 4 is driven to rotate, the brush base portion 4d rotates about the rotary shaft portion 4a. With this rotation, the brush member 4c inserted between the protrusions 4e repeatedly comes into contact with the object to be cleaned, so that dust present on the surface of the object to be cleaned is scraped up.

  Further, the hitting member 4b rotates around the rotating shaft 4a together with the brush base 4d as the rotating brush 4 rotates. The hitting member 4b is made of a material that is more flexible than the brush member 4c. Therefore, in the hitting members 4b1 and 4b3, the hitting part main bodies 4g1 and 4g3 are bent in a direction perpendicular to the rotary shaft part 4a by the centrifugal force generated by the rotation of the rotary shaft part 4a. As a result, in a state where the rotating shaft portion 4a is rotating, the hitting portion main bodies 4g1 and 4g3 of the hitting members 4b1 and 4b3 extend in a direction perpendicular to the rotating shaft portion 4a rather than the brush member 4c due to centrifugal force. Therefore, the hitting members 4b1 and 4b3 are more likely to come into contact with the surface of the object to be cleaned than the brush member 4c. Accordingly, in the rotary brush 4, the tapping members 4b1 and 4b3 strike the cleaning object immediately after the dust present on the surface of the cleaning object is scraped up by the brush member 4c.

  Further, as shown in FIG. 16, the hitting member 4b2 may be provided with a notch 4h on the side in contact with the cleaning object. When the hitting portion main body 4g2 is bent in a direction perpendicular to the rotation shaft portion 4a by the centrifugal force generated by the rotation of the rotation shaft portion 4a, the hitting portion main body 4g2 is configured to be short between the notch portions 4h. For this reason, the flexibility of the hitting portion main body 4g2 can flexibly correspond to the rotation of the rotating shaft portion 4a. As a result, the hitting effect can be sufficiently exerted.

Further, the notch 4h is disposed so as to be at the same position (the position indicated by the one-dot chain line L2 in FIG. 16) as the above-described arrangement of the rib 21b (the one-dot broken line L1 in FIGS. 4 and 20). That is, the notch 4h is provided in the rotary brush 4 at a position (a dashed line L2) that intersects with the dashed line L1 that is a virtual line extending along the rib 21b. Thereby, the rib 21b and the notch part 4h of the hitting part main body 4g2 are positioned on a substantially straight line. Therefore, when the rotating brush 4 rotates, the notch 4h causes a gap between the hitting part main body 4g2 and the rib 21b, and the tip of the hitting part main body 4g2 comes into contact with the tip of the rib 21b. Can be prevented. Further, by providing a gap between the hitting portion main body 4g2 and the rib 21b, it is possible to prevent a part of the cleaning object such as a futon from being caught in the rotating brush 4. Furthermore, since air flows in from the space between the ribs 21b through the gap, the portion of the cleaning object that faces the ribs 21b and the cleaner body 100 are easily separated from each other, and the cleaning object is effectively struck. Can do. The notch 4h is not limited to the hitting member 4b2, and may be provided in the hitting members 4b1, 4b3, for example. Preferably, the notch 4h is provided in a hitting member whose hitting part main body is not annular, for example, hitting members 4b2 and 4b3.

  In this way, the hitting member 4b hits the cleaning object as the rotating brush 4 rotates, so that the pest weakened by the exhaust air warm air from the electric blower 61 is released from the cleaning object. Therefore, the weakened pest can be efficiently sucked into the cleaner body.

  Further, in the electric vacuum cleaner according to the present embodiment, since the rotary brush 4 is provided with the hitting member 4b and the brush member 4c, the dust driving operation and the hitting of the object to be cleaned by the rotational driving force of the drive motor. Both operations are performed. Therefore, it is not necessary to separately provide a hitting mechanism for the object to be cleaned, and the weight and size of the cleaner body can be reduced.

  The shape of the hitting portion main body of the hitting member may be a shape that is flexible in a direction perpendicular to the rotation shaft portion 4a by the centrifugal force generated by the rotation of the rotation shaft portion 4a. For example, as shown in FIG. 15A, the hitting part main body 4g1 may have a ring-shaped cross section perpendicular to the rotation shaft part 4a. Further, as shown in FIG. 15B, the hitting portion main body 4g2 may have a shape in which a cross-sectional shape perpendicular to the rotation shaft portion 4a has a constricted portion. Further, the shape of the hitting portion main body 4g1 and 4g2 shown in FIGS. 15A and 15B is not limited, and as shown in FIG. The blade shape may be slanted.

  In the configuration of FIGS. 15A to 15C, the tapping members 4b1, 4b2.4b3 and the brush member 4c are provided two by two with respect to the brush base 4d, and are alternately arranged in the rotation direction. . However, the configuration of the hitting members 4b1 and 4b2.4b3 and the brush members 4c, such as the number and arrangement, is not limited to the configuration of (a) to (c) of FIG. It is possible to design appropriately according to various types.

FIG. 19C is a front view, and FIG. 19D is a top view.

  As shown in FIGS. 18 and 19, the storage table 400 supports the dust collection cup front end support portion 410 that supports the front end portion of the dust collection cup 210 in the dust collector 200 and the front end portion of the cleaner body 100. The vacuum cleaner main body front end support part 420 and the vacuum cleaner main body bottom part support part 430 which supports the bottom part of the vacuum cleaner main body 100 are provided.

  The vacuum cleaner 1 is stored in the storage table 400 while being supported by the dust collection cup front end support portion 410, the cleaner body front end support portion 420, and the cleaner body bottom support portion 430. When the vacuum cleaner 1 is stored in the storage table 400, the axis P of the dust collection cup 210 is set substantially in the vertical direction (gravity direction) in order to avoid the dust collected in the dust collection cup 210 from spilling. Is held to be.

  Thus, in the state where the vacuum cleaner 1 is stored in the storage table 400, the user can take out the dust collecting cup 210 as it is from the cleaner body 100 in the stored state. Therefore, the dust collection cup 210 can be easily maintained.

The following will describe still another embodiment of the present invention with reference to FIG. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted. FIG. 20 shows a configuration of the vacuum cleaner 1C according to the present embodiment. FIG. 20A is a bottom view as seen from the lower surface side, and FIG. 20B is a cross-sectional view.

  The vacuum cleaner 1C according to the present embodiment differs from the vacuum cleaner 1 according to the first embodiment in that ribs 21f are provided on the lower base 122 of the cleaner body 100 in addition to the partition walls 21c.

[Summary]
The vacuum cleaner 1 which concerns on aspect 1 of this invention is equipped with the vacuum cleaner main body 100 with which the electric blower 61 was incorporated and the suction inlet (opening part 21a) and the external discharge port 3 were formed in the bottom face facing a cleaning target object. The electric vacuum cleaner 1 that blows warm air heated by the exhaust heat of the electric blower 61 from the external discharge port 3 onto the object to be cleaned, and partitions the partition between the suction port and the external discharge port 3 21c is provided with respect to the bottom face of the cleaner body 100.

  According to said structure, since the partition wall 21c which partitions off between the said suction inlet (opening part 21a) and the said external discharge port 3 is provided with respect to the bottom face of the said cleaner body 100, an external discharge port It is possible to prevent the warm air discharged from 3 from being sucked into the suction port (opening 21a). Therefore, excessive circulation of exhaust air between the suction port (opening 21a) and the external discharge port 3 in the vacuum cleaner body 100 can be prevented, and excessive temperature rise of the vacuum cleaner body 100 due to exhaust circulation. Can be prevented.

The vacuum cleaner 1 which concerns on aspect 2 of this invention is equipped with the rotary body (roller 16) which assists the movement of the said vacuum cleaner main body 100 in the said aspect 1, The rotary body accommodation which accommodates the said rotary body (roller 16). The partition wall 21c may be a part of the side wall constituting the portion (roller accommodating portion 21d).

  According to said structure, the movement of the vacuum cleaner 1 becomes easy and operativity improves.

  The vacuum cleaner 1 according to aspect 3 of the present invention is the above-described aspect 1 or 2, wherein the circuit board (main body circuit board 8) that controls the operation of the vacuum cleaner main body 100 and the board accommodation unit ( Circuit board housing portion 68b), and the upstream side of the external discharge port 3 in the flow path inside the cleaner body 100 from the suction port (opening 21a) to the external discharge port 3. An exhaust filter 7 for purifying the wind is disposed, and the flow path of the warm air passes through the first flow path Z1 toward the external discharge port 3 without passing through the substrate housing section, and the first flow path passing through the substrate housing section. The first and second flow paths Z1 and Z2 may branch to the second flow path Z2 and pass through the exhaust filter 7 together.

  In the vacuum cleaner 1 that applies hot air to the object to be cleaned using the exhaust heat of the electric blower 61, an exhaust filter 7 is mounted to purify the air discharged to the outside. Further, since the vacuum cleaner 1 is equipped with a control device such as a circuit board (main circuit board 8), the hot air heated by the electric blower 61 is supplied to the board housing portion (for the cooling of the circuit board). It is necessary to flow into the circuit board housing portion 68b).
