Description

  The present invention relates to a vacuum cleaner body including a vacuum cleaner body including a dust collection chamber and a blower, a suction body for sucking dust, and a suction hose communicating the suction body and the vacuum cleaner body. In particular, the present invention relates to a cyclone type electric vacuum cleaner provided with a dust collection chamber that separates dust by eddy currents.

  2. Description of the Related Art In recent years, a vacuum cleaner called a cyclone that generates a vortex in a cylindrical dust collection chamber and separates dust from an air flow has become widespread. This cyclone type vacuum cleaner takes an air flow containing dust from the circumferential direction of a cylindrical dust collecting chamber through a blower to generate a vortex, and separates the dust and the air flow by the centrifugal force of this vortex, It has a structure for taking out an air flow from which dust is separated from the center of the dust collecting chamber. After the fine dust is removed by the first filter, the air flow taken out from the dust collecting chamber is taken into the blower, and after cooling the blower, the air flow is discharged out of the housing of the cleaner.

  For example, according to the prior art disclosed in Patent Document 1, a vertically arranged blower and a cord reel are arranged side by side behind a vertically arranged cylindrical dust collection chamber, and the exhaust flow taken into the blower is transferred to the back surface of the casing. The structure of exhausting from the exhaust port provided in the upper part is disclosed. In this conventional example, since the rear surface of the housing provided with the exhaust port is adjacent to the blower, there is a problem that noise generated from the blower is directly transmitted from the exhaust port. In this conventional example, although a filter is provided at the exhaust port to enhance the exhaust flow cleaning effect, a part of the exhaust flow exhausted from the blower is branched to the cord reel portion without passing through the filter. There is a problem that air is exhausted from the cord reel hole.

  For example, Patent Document 2 discloses a structure in which an air intake port of a blower is directed toward the dust collection chamber for the purpose of noise reduction. In this conventional example, a filter for removing fine dust is provided at the front portion of the blower. Further, the exhaust flow discharged from the rear of the blower is discharged from the front part on both side surfaces of the housing through the exhaust passages on both side surfaces of the housing.

  In addition, for example, in Patent Document 3, a cylindrical dust collection chamber is disposed obliquely rearward so that a space is secured between the lower portion of the dust collection chamber and the blower, and a sound deadening function is provided in this space. A technique in which a filter housing having an air cleaning function is arranged is disclosed. In this conventional example, the exhaust flow exhausted from the filter housing is exhausted obliquely rearward through an exhaust duct provided on the side of the casing, and part of the exhaust is exhausted from the casing below the dust collection chamber. Is done.

  First, a schematic structure of a vacuum cleaner according to the present invention will be described with reference to FIG. A major feature of this electric vacuum cleaner is that it has a compact structure that has a high exhaust purification effect and can achieve low noise.

  In FIG. 1, this vacuum cleaner is comprised including the vacuum cleaner main body generally shown by the code | symbol 1, and the suction | inhalation assembly 2 attached to the hose attachment part 21 of this vacuum cleaner main body 1 so that attachment or detachment is possible. The For example, the suction assembly 2 includes a suction hose portion (not shown) to which one end is attached, a handle portion (not shown) attached to the other end of the suction hose portion, and an extension pipe portion (not shown) to which one end is attached to the handle portion. And a suction body (not shown) attached to the other end of the extension pipe portion. However, the present invention is not limited to this, and it is only necessary to include a connection tool (not shown) that is detachably attached to the hose attachment portion 21 and a suction body that is attached to the connection tool.

  According to this electric vacuum cleaner, by starting the blower 41 provided in the electric vacuum cleaner main body 1, the air flow X containing dust can be sucked from the suction body, and the air flow X taken in by the suction body Can be taken into the main body 1 of the vacuum cleaner via the extension pipe part, the handle part and the suction hose, and the hose attachment part 21 is provided with a power connection part (not shown). By connecting an extension tube or the like, power can be supplied to the mouthpiece through the power supply connecting portion.

  The vacuum cleaner main body 1 according to this embodiment employs a dust collection method called a cyclone method including a cylindrical dust collection case 100 that separates dust and air flow by eddy current. That is, the vacuum cleaner main body 1 includes a dust collection case 100 and a main body housing 10 provided with a dust collection case mounting portion 150 for detachably attaching the dust collection case 100.

  As shown in the cross-sectional view shown in the blowout of FIG. 1, the vacuum cleaner body 1 is disposed side by side on the left and right behind the dust collection case 100 that is held in an obliquely tilted posture. A large skeleton is formed by the air blowing chamber 40 and the cord reel chamber 50 (see FIGS. 6 and 7) and the filter chamber 60 formed between the air blowing chamber 40 and the cord reel chamber 50 and the lower part of the dust collecting case 100. Forming. The vacuum cleaner main body 1 can be pulled by the suction assembly 2 with a pair of large wheels 12 and a free wheel 11.

  The dust-collecting case mounting part 150 is formed in a concave shape with the upper part open at the upper front part of the main body housing 10. And this concave dust collection case mounting part 150 is comprised by V shape seeing from the side surface, and has a structure which hold | maintains the substantially cylindrical dust collection case 100 in the diagonal attitude | position. Therefore, the dust collection case 100 can be easily attached and detached from the opened upper side. In this embodiment, in order to maintain the mounted state, an openable and closable upper cover 22 is provided, and the upper cover 22 is closed to maintain the mounted state of the dust collecting case 100.

  The V-shaped front inclined surface 151 of the dust collection case mounting portion 150 is provided with a concave air inlet 152 for supplying an air flow X containing dust to the dust collection case 100. A blower chamber air inlet 154 for guiding the airflow X that has passed through the dust collecting case 100 to the blower chamber 40 is provided on the upper portion of the rear inclined surface 153.

  Further, a hose attachment portion 21 for attaching a suction hose is provided at the forefront portion of the main body housing 10. Since the hose attachment portion 21 communicates with the air inlet 152, the air flow X including dust taken in from the suction hose can be guided to the dust collecting case 100.

  A dust collection case 100 according to this embodiment includes a first case 110 that forms eddy currents, a second case that includes a dust trap 121 that captures large dust and a first dust collection filter 122 that captures fine dust. 120 is detachably connected. Since these two cases are formed of transparent resin, it is possible to confirm the dust trapping state and the eddy current movement in the dust collecting case 100 from the outside.

  The first case 110 has a protruding air inflow receiving port 111 connected to the air inlet 152 at one end, and the other end communicates with the second case 120. On the other hand, the second case 120 is provided with a dust trap 121 at one end thereof and communicated with the first case 110, and a first dust collecting filter 122 is provided at the other end. By attaching the dust collection case 100 to the dust collection case mounting portion 150, the air inlet 152 and the air inflow receiving port 111 communicate with each other, and further, the first dust collection filter 122 and the blower chamber air inlet 154 are connected. And the air flow X from which dust is removed can be guided to the blower chamber 40.

  In the blower chamber 40, a blower 41 in which the rotation axis P <b> 3 is arranged in the vertical direction and the air intake 44 is arranged in the upper part is arranged in a vertical posture. The air flow X taken into the blower chamber 40 from the blower chamber air inlet 154 is taken into the blower 41 through the blower chamber upper flow passage 45 a formed in the upper part of the blower chamber 40. The airflow X taken into the blower 41 cools the electric motor 43 of the blower 41 and is then discharged into the front filter chamber 60.

  The filter chamber 60 is provided with a second dust collection filter 61 that removes finer dust. The air flow X taken into the filter chamber 60 passes through the second dust collection filter 61, thereby Air that is as clean as a cleaner can be obtained. Therefore, by providing the structure that allows the second dust collection filter 61 to pass therethrough, the exhaust purification effect can be enhanced.

  One of the major features of the electric vacuum cleaner according to the present invention is that the dust collection case 100 inclined obliquely rearward and the blower chamber 40 provided with the blower 41 in the vertical posture with the rotation axis P3 vertical. By combining them, a space is secured between the dust collection case 100 and the air blowing chamber 40, and the filter chamber 60 including the second dust collection filter 61 is disposed in this space.

  That is, the vacuum cleaner main body 1 can suck dust together with the airflow by the suction force formed by the blower 41. Therefore, in this embodiment, since the airflow X from which dust has been removed can be taken into the blower 41 through a straight path, the loss of the blower 41 can be reduced. That is, in this embodiment, since the rotation axis P3 of the electric motor 43 is vertical and the fan 42 and the electric motor 43 are arranged vertically, the air intake 44 can be arranged in the upper part of the blower chamber 40. As a result, the air flow X taken into the blower chamber 40 from the blower chamber air inlet 154 can be taken into the air intake 44 as it is from the blower chamber upper flow passage 45a. Further, the air flow X taken into the blower 41 can be sent to the adjacent filter chamber 60 after cooling the downwind motor 43 of the fan 42.

  On the other hand, the second dust collection filter 61 having a high air cleaning function requires a large area in consideration of the loss of the blower 41. Therefore, where the large second dust collection filter 61 is arranged in the main body housing 10 greatly contributes to the compactness of the vacuum cleaner main body 1. In this embodiment, the cylindrical dust collecting case 100 is tilted backward so that a space is secured in the front part of the blower chamber 40 disposed at the rear part of the main body housing 10, and this space is used as a filter chamber. 60.

  The position where the filter chamber 60 is disposed is a position adjacent to the electric motor 43 disposed in the blower chamber 40 and the center of the main body housing 10, which hinders the compactness of the main body housing 10. It is a position where there is little to cause. And the center position of this main body housing | casing 10 is also a position which can contribute largely to sound reduction.

  In addition, another major feature of the electric vacuum cleaner according to the present invention is that this cleaning effect is achieved by disposing a filter chamber 60 that generates an exhaust flow with high cleanliness in the center of the main body housing 10. This is because it is easy to form a long exhaust passage for exhausting high exhaust gas out of the main body housing 10 with low noise.

  That is, in this embodiment, as shown in FIG. 9, a main exhaust passage 70 is provided at the lower portion of the blower chamber 40 to guide exhaust having a high cleaning effect to the rear, and the rear end side of the main exhaust passage 70 from the rear side. The exhaust passage 75, the cord reel exhaust passage 80, and the bumper exhaust passage 85 are branched.

  Returning to FIG. 1, the rear-side exhaust passage 75 is a passage formed between the rear end of the main exhaust passage 70 and the rear surface of the main body housing 10 and the blower chamber 40, and the air passing through the rear-side exhaust passage 75. The flow X is discharged out of the main body casing 10 from a rear exhaust port 23 formed at the upper back of the main body casing 10. Further, the front end of the back surface exhaust passage 75 communicates with the upper surface of the main body housing 10 and is guided to the ion generation chamber 90 provided at the rear of the upper surface of the main body housing 10. The ion generation chamber 90 is provided with an ion generation unit 91 and an ion discharge port 24. The ions generated by the ion generation unit 91 are included in the exhaust gas guided to the ion generation chamber 90 and are discharged from the main body housing 10 through the ion discharge port 24.

  The cord reel exhaust passage 80 is a passage extending from the rear end portion of the main exhaust passage 70 through the cord reel chamber 50 to the cord outlet 25 (see FIGS. 4 and 6) formed in the upper part of the back surface of the main body casing 10. is there. Thereby, the cord reel 51 provided in the cord reel chamber 50 can be cooled.

  The bumper exhaust passage 85 is exhausted from the bumper exhaust ports 27 formed at the front portions on both sides of the bumper 26 through the bumper exhaust passages 85 formed on both sides of the main body housing 10 from the rear end portion of the main exhaust passage 70. The

  As described above, the vacuum cleaner main body 1 according to this embodiment allows the exhaust flow having a high air cleanliness generated in the central filter chamber 60 of the main body casing 10 to pass through the main exhaust passage 70 through the main exhaust passage 70. Since one end is returned to the position behind the lower part, and the exhaust is extended from the position behind the lower part from the rear exhaust port 23, the bumper exhaust port 27, etc. provided at the upper rear part of the main body housing 10 and the front part on both side surfaces. Therefore, noise transmitted through the exhaust passage can be reduced. Further, since the flow speed of the exhaust gas is reduced by the long exhaust passage, noise such as wind noise can be reduced.

  Another major feature of the electric vacuum cleaner according to the present invention is that noise is reduced by adopting a structure in which the blower 41, which is a main source of noise, is surrounded by an exhaust passage.

  That is, in this embodiment, the dust collection case 100 and the filter chamber 60 are disposed in the front part of the air blowing chamber 40, the main exhaust passage 70 is disposed in the lower part of the air blowing chamber 40, and the rear side exhaust passage is disposed behind the air blowing chamber 40. 75, a bumper exhaust passage 85 is disposed on one side of the blower chamber 40 in addition to the cord reel chamber 50 and the large wheel 12, and a bumper exhaust passage 85 is disposed on the other side of the blower chamber 40 in addition to the large wheel 12. In addition to the blower chamber upper flow passage 45a and a silencer (not shown), an ion generation chamber 90 is disposed at the upper portion of the blower chamber 40. Thereby, the noise which generate | occur | produces in the ventilation chamber 40 can be suppressed low. In particular, low noise is realized by configuring the main passage of the exhaust passage from the main exhaust passage 70 formed in the lower part of the blower chamber 40 to the back side exhaust passage 75 formed on the back surface of the main body housing 10. doing.

  Another major feature of the electric vacuum cleaner according to the present invention is that the exhaust flow is dispersed from the rear portion of the main exhaust passage 70 to a plurality of exhaust passages, thereby reducing the momentum. it can. In addition, since the exhaust ports such as the rear exhaust port 23 and the bumper 26 are provided at a high position in the main body housing 10, it is possible to reduce the exhaust from hitting the floor and raising dust.

  Another major feature of the vacuum cleaner according to the present invention is a structure in which the first dust collection filter 122 of the dust collection case 100 and the second dust collection filter 61 of the filter chamber 60 are arranged vertically. In the point.

  That is, in this embodiment, the first dust collection filter 122 in the vertical posture with the ventilation surface in the front-rear direction and the second dust collection filter 61 in the posture with the ventilation surface in the front-rear direction are disposed vertically. The main body housing 10 is divided into two parts by two filters. Thereby, the noise to the front which generate | occur | produces in the ventilation chamber 40 can be reduced with these two filters. In addition, by arranging two large filters at the center position of the main body casing 10, the vacuum cleaner main body 1 can be formed in a mountain-shaped appearance with the center of the main body casing 10 as the apex. The electric vacuum cleaner main body 1 with a compact feeling is realized by reducing the 10 volume feeling.

  Another major feature of the electric vacuum cleaner according to the present invention is that the control board 46 is arranged in the main exhaust passage 70.

  That is, in the conventional vacuum cleaner, it is common to provide a cord reel button and an operation display part at the rear of the upper surface of the vacuum cleaner body 1. That is, in the prior art, the control board is disposed above the blower chamber 40 and the cord reel chamber 50. However, the position behind the upper surface of the vacuum cleaner main body 1 has a problem that it is difficult to cool because the exhaust flow exhausted from the blower chamber 40 is difficult to rotate. In addition, there is a problem in that, by arranging the plate-like control board 46, the shape of the back surface of the main body housing 10 is difficult to be rounded.

  Therefore, in this embodiment, by arranging the thin control board 46 in the thin main exhaust passage 70 formed below the blower chamber 40, the arrangement space for the control board 46 is ensured and the cooling is enabled.

  Another major feature of the vacuum cleaner according to the present invention is that the operation state display unit 47 is arranged on the front inclined surface 151. That is, in this embodiment, since the control board 46 is disposed on the bottom surface portion of the main body casing 10, there is a problem that the connection becomes long when the operation state display section 47 is disposed on the upper portion of the main body casing 10. Therefore, in this embodiment, paying attention to the fact that there is a space in the front part of the filter chamber 60 and the dust collecting case 100 is transparent, a state display unit substrate provided with a light emission source 49 in the front part of the filter chamber 60. 48, and an operation state display unit 47 that diffuses light from the light emission source 49 is disposed on the front inclined surface 151 of the dust collection case mounting unit 150.

  According to this embodiment, the state display unit substrate 48 can be disposed by utilizing the pointed portion of the front part of the filter chamber 60 that is substantially triangular (side shape) by the dust collection case 100 inclined rearward. Mounting efficiency can be increased. Since the position of the state display unit substrate 48 is close to the control substrate 46, it is not necessary to lengthen the wiring. Further, since the front inclined surface 151 is a portion that supports the bottom surface of the cylindrical dust collecting case 100, the dust collecting case 100 (particularly, the first dust collecting case 100 (particularly, the first dust collecting case 100) is obtained by making the front inclined surface 151 shine by the operation state display unit 47. Since the case 110) can be a light diffusion portion, the visibility of the driving state display unit 47 can be improved.

  Hereinafter, the vacuum cleaner according to this embodiment will be further described with reference to FIGS.

  First, the schematic structure of the dust collection case 100 will be further described with reference to FIG. 2A is a perspective view of the second case 120, FIG. 2B is a longitudinal sectional view of the second case, FIG. 2C is a perspective view of the first case, and FIG. 2B is a perspective view of the first case. It is a longitudinal cross-sectional view.

  2A and 2B, the second case is attached to a cylindrical second case main body 123 formed of a transparent resin material and to one end of the cylindrical second case main body 123 so as to be opened and closed. A dust collecting lid 124 and a first dust collecting filter 122 attached to the other end of the cylindrical second case main body 123 are configured. The second case main body 123 has a cylindrical shape bent at an angle of about 45 degrees, and a handle portion 125 is provided on the outer periphery of the upper case.

  The dust collection lid 124 is attached so as to be openable with the lower end portion (side facing the handle portion 125) as a rotation axis. This opening / closing operation can be opened by operating a lock button 126 provided at the front portion of the handle portion 125. The dust collection lid 124 is formed with a pair of openings 127 that allow the first case 110 and the second case 120 to communicate with each other. That is, the opening 127 includes a central opening 127b formed at the center of the dust collecting lid 124 and a side opening 127a formed on one side.

  In addition, a dust trap 121 is movably attached to the inside of the dust collection lid 124 via a rotation shaft disposed in the vicinity of the rotation shaft of the dust collection lid 124. As a result, when the dust collecting lid 124 is opened, the dust trapping part 121 also protrudes out of the cylinder with this movement. According to this structure, the dust collection lid 124 is opened by the opening operation of the lock button 126, and the dust trapping part 121 also jumps out of the cylinder by this opening operation. Therefore, the dust collected in the dust trapping part 121 is removed from the outside of the cylinder. Can be thrown away.

  Here, the side opening 127a is an opening through which relatively large dust passes. The large dust taken into the first case 110 is collected on the inner peripheral surface of the first case 110 by the action of centrifugal force of the eddy current, and the collected large dust is collected along with the air flow from the side opening 127a. The data is captured by the unit 121. Large dust is captured by the dust trap 121 and only the air flow passes through the dust trap 121.

  On the other hand, fine dust that is not centrifuged by the eddy current is taken into the second case 120 without passing through the dust trap 121 from the central opening 127b. Then, the air flow that does not include large dust taken in from the central opening portion 127b and the side opening portion 127a merges in front of the first dust collection filter 122, and all the flow flows in the first dust collection filter 112. Will pass.

  Note that a check ben (not shown) can be provided in the opening 127 of the dust collecting lid 124. In this case, it is preferable to provide a check bent at the side opening 127a through which large dust passes.

  2 (c) and 2 (d), the first case 110 is formed of a transparent resin material in which an air inflow receiving port 111 projects from one end of a cylindrical shape and the other end of the cylindrical shape is largely open. 1 case main body 112 and the connection cover 113 attached to the open part side of this 1st case main body 112 are comprised. The connection cover 113 has a structure for generating a vortex and also has a function of connecting to the dust collection lid 124. The connection cover 113 has an opening 114 formed of a central opening 114b formed at the center of the connection cover 113 and a side opening 11a provided on one side. The central opening 114b communicates with the central opening 127b, and the side opening 114a communicates with the side opening 127a.

  1 and 2, according to the dust collecting case 100 according to this embodiment, the air flow X including dust taken in from the air inflow receiving port 111 is taken in the circumferential direction of the inner wall surface of the first case 110. As a result, a swirl is generated in the first case 110, and the swirl is separated by large dust and small dust, and the large and small dusts separated by the separation are separated from the opening 114 through the opening 127, and the second case. The air flow taken in 120 and containing the large dust passes through the dust trapping portion 121, so that the large dust is removed. Then, the air flow X from which the large dust has been removed and the air flow X containing fine dust merge in front of the first dust collecting filter 122, and the air flow containing fine dust that has joined together is the first case. It is bent by the main body 112, taken into the first dust collecting filter 122, and fine dust is further removed and discharged out of the dust collecting case 100.

  Next, with reference to FIG. 3 and FIG. 4, the external structure of the vacuum cleaner main body 1 which concerns on this Example is demonstrated concretely. 3 is an external perspective view, FIG. 4A is a plan view, FIG. 4B is a left side view, FIG. 3C is a front view, FIG. 3D is a right side view, e) The figure shows a bottom view and (f) the figure shows a rear view.

  In the figure, the vacuum cleaner main body 1 has a dust collection case 100 and a main body housing 10 that are disposed in a detachable manner in a tilted posture that tilts backward at the front front part by closing the upper cover 22. Can be made into an inseparable structure. Moreover, the vacuum cleaner main body 1 arrange | positions the large wheel 12 in the back of both sides | surfaces, and the one universal wheel 11 is arrange | positioned in the front part of the bottom face. Thereby, a floor surface can be made to run freely.

  The appearance characteristic of the vacuum cleaner main body 1 is in the shape of a bumper 26 that holds a cylindrical dust collecting case 100 in an inclined posture and a pair of large wheels 12. The bumper 26 includes a first bumper 26 a that supports the longitudinal direction of the cylindrical dust collection case 100, a second damper 26 b that supports the bottom of the cylindrical dust collection case 100, and a pair of large wheels 12. The third bumper 26c is covered and has a unique shape in which the three bumpers are bent and continuous.

  That is, the first bumper 26a is formed to be elongated along the longitudinal direction of the dust collecting case 100, and the second damper 26b is continuously bent by bending the upper end of the first bumper 26a by 90 degrees with the same width. The outer skeleton of the vacuum cleaner main body 1 is formed by bending the first bumper 26a 90 degrees downward from the upper end and continuing the thick third bumper 26c. According to the modeling of the bumper 26, the characteristics of the vacuum cleaner main body 1 that firmly holds the dust collecting case 100 and has a feeling of movement by the large wheels 12 are expressed. Moreover, according to the formation of the bumper 26, the dust collecting case 100 can be protected from impact, and as shown in FIG. 4A, the front portion of the main body housing 10 having a narrow width and the thick main body having a wide width. Since the rear part of the housing 10 is formed in a continuous shape with a rounded gentle curve, the obstacle can escape in a rounded shape even when hitting a pillar or the like during pulling.

  In addition, a front overhang portion 33 is formed in the lower portion of the second damper 26b, and the hose attachment portion 21 is provided in the front overhang portion 33. According to this structure, since the hose attachment part 21 can be arrange | positioned in the center of a front, the suction inlet assembly 2 can be connected with the hose attachment part 21 straightly. Thereby, pulling traveling can be made favorable by the mouthpiece assembly 2. Moreover, since the cylindrical dust collecting case 100 is inclined backward, the air inlet 111 (see FIG. 1) of the dust collecting case 100 is set at a gentle angle with respect to the suction assembly 2 that is attached straight. Can be linked.

  Further, since the upper cover 22 is formed along the extension line of the upper side of the third bumper 26c, the volume feeling of the dust collecting case 100 can be reduced. Further, the angled bent portions of the first bumper 26 a and the third bumper 26 c are located at the approximate center of the front and rear of the vacuum cleaner body 1. Since the center position coincides with the two filters (the first dust collection filter 122 and the second dust collection filter 61 shown in FIG. 1) arranged in a stacked manner, the internal layout and the appearance are matched. And since the front part of the upper surface of the vacuum cleaner main body 1 has a front-lowering slope and the rear part has a slightly inclined rearward shape from the center part with this height, the volume feeling of the entire vacuum cleaner body 1 To achieve a compact appearance.

  Moreover, as shown in FIG. 4, the main handle | steering-wheel part 29 which can be made to raise a front part as a rotating shaft is provided in the upper surface back of the vacuum cleaner main body 1. As shown in FIG. The main handle portion 29 is formed so as to surround the ion generation chamber 90 (see FIG. 1) in the folded state, and its upper surface is formed flat. The ion discharge port 24 and the cord reel button 28 are disposed on the flat portion.

  A rear exhaust port 23 and a cord outlet 25 are arranged side by side on the upper part of the rear surface of the main body housing 10. Thereby, since it can exhaust from a high position, it can reduce raising the dust of a floor surface. Further, a fixed leg portion 30 is provided at the upper part of the back surface of the main body housing 10, and the electric vacuum cleaner main body 1 is mounted in a vertical posture with the back surface as a bottom surface with the fixed leg portion 30 and a pair of large wheels 12. Can be installed.

  In addition, a concave fixed handle 31 is provided at the bottom front portion of the main body casing 10 and can be held and transported at the top of the vacuum cleaner main body 1 in the vertical posture. Furthermore, a first opening lid 71 that opens the main exhaust passage 70 and the filter chamber 60 and a second opening lid 52 that opens the cord reel chamber 50 are attached to the bottom surface with screws or the like (not shown). By making the first open lid 71 and the second open lid 52 openable, it is possible to maintain the internal devices disposed in the main exhaust passage 70, the filter chamber 60, and the cord reel chamber 50. Note that the second opening lid 52 need not be provided.

  Next, with reference to FIG. 5 to FIG. 9, the specific structure of each part will be further described according to the flow of the air flow X of the electric vacuum cleaner main body 1 according to this embodiment.

  First, the hose attachment portion 21 to which the suction mouth assembly 2 is attached is formed at the foremost portion of the main body housing 10 so that the tube axis P1 is horizontal with the floor surface. In a normal use state, the vacuum cleaner main body 1 is attached with a suction hose (not shown) that is flexible and constitutes the suction mouth assembly 2 to the hose attachment portion 21, and runs by pulling with the suction hose. In this embodiment, the hose attachment portion 21 is arranged at the forefront of the main body housing 10 so that the tube axis P1 is horizontal with the floor surface, so that the strength sufficient to withstand pulling by the suction mouth assembly 2 can be obtained. it can. And since the hose attachment part 21 is provided in the right-and-left symmetrical position of the vacuum cleaner main body 1, it can make favorable the straightness of the pulling | running | working traveling by the suction mouth assembly 2.

  Further, an impact bumper 32 is formed below the front projecting portion 33 where the hose attachment portion 21 is provided. Since the concave fixed handle 31 for improving the strength of the impact bumper 32 is formed behind the impact bumper 32, it is possible to withstand an impact with an obstacle during pulling traveling by the suction mouth assembly 2. .

  Further, the hose attachment portion 21 is connected to the rear air inlet 152. The air inlet 152 is provided in the concave portion 155 of the front inclined surface 151 of the dust collection case mounting portion 150. In this embodiment, since the dust collecting case 100 is held in the posture of being tilted backward, it is necessary to bend the airflow X including dust taken in the horizontal direction by the hose attachment portion 21. Therefore, in this embodiment, the air flow X is bent by providing an air inflow receiving port 111 formed obliquely on the bottom surface of the dust collecting case 100. The recess 155 connects the protruding air inflow port 111 and the air inflow port 152 to each other.

  Here, since the coupling surface 111 a between the air inflow receiving port 111 and the air inflow port 152 is formed obliquely, the air flow X including the dust taken in the horizontal direction by the hose attachment portion 21 is generated at the air inflow receiving port 111. The tip portion (coupling surface 111a) and the base portion 111b of the air inflow receiving port 111 are gently bent in two stages and taken into the first case 110 of the dust collecting case 100.

  The airflow X containing dust taken into the first case 110 of the dust collecting case 100 is formed into a vortex in the first case 110 by the guide of the connection cover 113 and taken into the second case 120 from the opening 114. . Here, since the large dust captured in the dust trapping part 121 is compressed in the dust trapping part 121 by the suction force of the airflow, even when the second case 120 is removed and the dust is thrown away, the dust trapping part Falling from 121 through the side opening 127a is reduced.

  In addition, even when the dust collecting case 100 is attached to the cleaner body 1 (set state) or when the second case 120 is held via the handle portion 125 (conveyed state), the side opening 127 a Since it is located in the center part of the capture part 121, it can reduce that dust falls from this side opening part 127a. Similarly, in the set state and the transport state, the fine dust of the first dust collecting filter 122 removed by the dust removing device 180 collects at the corner portion which is the lower position of the second case 120, and falls from the opening 127. Is alleviated. Thereby, since dust does not collect in the 1st case 110, generation | occurrence | production of a eddy current becomes favorable. In this embodiment, a check bent (not shown) may be provided in the opening 127 of the second case 120.

  The airflow X including the dust taken in the second case 120 passes through the dust trapping part 121 provided so as to protrude greatly in the second case main body 123. Since the dust trapping part 121 is formed of a net, most dust can be trapped. The airflow X from which the large dust has been removed by the dust trapping part 121 passes through the first dust collecting filter 122 held in a vertical posture, further removes fine dust, and blows from the blower chamber air inlet 154. It is taken into the chamber 40. Here, as shown in FIG. 6, the first dust collection filter 122 has a bellows-like structure folded in the left-right direction. Thereby, fine dust can be removed with a large area.

  Returning to FIG. 5, the dust collection case 100 employed in this embodiment includes a dust trap 121 that removes rough dust from the air flow, and a first dust collection filter 122 that removes fine dust from the air flow. Therefore, by removing the dust collecting case 100 from the main body housing 10, rough dust and fine dust can be collectively discarded. This collective disposal structure is extremely advantageous in handling compared to the prior art in which the dust trapping part and the first dust collecting filter are separately provided in the main body housing.

  In this embodiment, in order to realize the dust collection case 100 capable of batch disposal, a dust collection case formed in a concave shape with a front inclined surface 151 and a rear inclined surface 153 at the front upper surface of the main body housing 10. A mounting portion 150 is formed, and the dust collection case mounting portion 150 has a structure in which the dust collection case 100 is detachably held in an oblique posture. According to this structure, the airflow X containing dust taken in horizontally by the hose attachment portion 21 is bent obliquely upward and taken into the dust collecting case 100, and after removing dust in the dust collecting case 100, The airflow X can be taken into the main body housing 10 from above the dust collection case 100 in the horizontal direction.

  In this embodiment, the first dust collecting filter 122 is disposed at the final outlet of the air flow X of the dust collecting case 100. According to this structure, the first dust collection filter 122 can be held adjacent to the blower chamber air inlet 154 in a vertical posture. Thereby, the dust removal mechanism 180 of the 1st dust collection filter 122 can be provided in the ventilation chamber air inflow port 154.

  That is, as shown in FIG. 6, the first dust collection filter 122 of this embodiment is arranged in a bellows shape in the left-right direction. In the air inlet 154 adjacent to the first dust collection filter 122, a vibration unit 181 that vibrates in the folding direction (left and right direction) of the first dust collection filter 122, and a drive unit that drives the vibration unit 181. A dust removal mechanism 180 made of 182 is arranged. According to this structure, when the drive unit 182 is operated, the vibration unit 181 vibrates in the folding direction (left-right direction) of the first dust collection filter 122. Due to this vibration, fine dust adhering to the dust collection case 100 side (upper part of the drawing) of the first dust collection filter 122 falls to the dust collection case 100 side (upper part of the drawing). At this time, as shown in FIG. 5, since the first dust collection filter 122 is mounted in a vertical posture, the dust adhering to the first dust collection filter 122 falls to the dust collection case 100 side (upper part of the drawing) as it is. It becomes easy to do.

  Further, in this embodiment, when the dust collection case 100 is mounted on the dust collection case mounting portion 150, the air inflow receiving port 111 protruding from the lower portion of the dust collection case 100 is inserted into the recess 155, and positioned. Thereafter, since the upper part of the dust collection case 100 is structured to be attached to the dust collection case attachment part 150, the attachment is easy. The upper part of the dust collection case 100 can be fixed to the main body housing 10 that fixes the dust collection case 100 by closing the upper cover 22.

  5 and 6, the air flow X taken into the blower chamber 40 is taken into the blower 41 from the air intake port 44 opened at the upper part of the blower 41 through the blower chamber upper flow passage 45a. As shown in FIG. 6, in this embodiment, the blower chamber 40 and the cord reel chamber 50 are arranged side by side, and the airflow X taken in from the blower chamber air inlet 154 is taken into only the blower chamber 40.

  Here, as shown in FIGS. 6 and 7, the cord reel 51 disposed in the cord reel chamber 50 is disposed in a posture in which the rotation axis P <b> 2 is the left-right direction. Thereby, the cord 53 wound around the cord reel 51 can be pulled out backward (downward in the drawing) from the cord outlet 25 provided on the back surface of the main body housing 10.

  On the other hand, as shown in FIG. 5, in the blower 41 of the blower chamber 40, the fan 42 and the electric motor 43 are arranged vertically so that the rotation axis P3 is vertical. As a result, the air flow X taken in from the blower chamber air inlet 154 in the horizontal direction is bent downward by the blower chamber upper flow passage 45 a and the air intake 44 and taken into the blower 41.

  The air flow X taken into the blower 41 is sent to the electric motor 43 by the fan 42 to cool the rotating electric motor 43, and as shown in FIG. 45b. Since the blower chamber lower flow passage 45b is open only to the front (upper drawing) filter chamber 60 side, the air flow X that has cooled the electric motor 43 is fed into the filter chamber 60.

  As shown in FIGS. 7 and 8, the filter chamber 60 is formed with the full width of the main body housing 10 so as to be positioned in front of the cord reel chamber 50 and the filter chamber 60. The second dust collection filter 61 provided in the filter chamber 60 is formed to fill the width of the filter chamber 60. For this reason, the opening part ahead of the ventilation chamber lower flow passage 45 b is opened to the left and right so as to allow the air flow X to pass through the entire second dust collection filter 61 and communicates with the filter chamber 60. Therefore, most of the air flow X fed into the filter chamber 60 passes through the second dust collecting filter 61 and becomes a purified air flow X having a cleanliness equivalent to that of the air cleaner.

  Here, the second dust collection filter 61 employed in this embodiment employs a large HEPA block filter with improved dust collection performance. Thereby, fine particles can be collected.

  Returning to FIG. 5, as described above, in this embodiment, the air flow X taken into the rear air blowing chamber 40 from the dust collecting case 100 is turned in the air blowing chamber 40 and sent to the front filter chamber 60. An air flow X having a high air cleanliness is generated in the filter chamber 60 in the center of the main body housing 10.

  As shown in FIGS. 5 and 9, in this embodiment, a thin main exhaust passage 70 is formed in the lower portion of the blower chamber 40. As a result, the air flow X sent into the filter chamber 60 is turned again at the front portion of the filter chamber 60 and is sent backward via the main exhaust passage 70. A control board 46 is disposed in the main exhaust passage 70. Thereby, the control board 46 can be cooled with the cleaned airflow X. The main exhaust passage 70 may be provided with the lower end portion of the electric motor 43 protruding. Thereby, the enlargement of the main body housing | casing 10 can be reduced.

  Thus, in this embodiment, by providing the main exhaust passage 70 below the blower chamber 40, the exhaust passage is secured, and the control board 46 is disposed in the exhaust passage, or a part of the electric motor 43 is provided. Thus, mounting efficiency can be improved without increasing the size of the apparatus.

  Returning to FIG. 5, in this embodiment, the clean air flow generated in the filter chamber 60 at the center of the main body casing 10 is passed through the main exhaust passage 70 to the rear end of the main body casing 10. Therefore, a structure is adopted in which the rear end portion of the main exhaust passage 70 is dispersed into a plurality of exhaust passages.

  That is, the main part of the exhaust passage is communicated from the rear end portion of the main exhaust passage 70 to the back side exhaust passage 75 formed behind the blower chamber 40. The back side exhaust passage 75 is formed long in the vertical direction, and the back side exhaust port 23 is provided at a position above it. Accordingly, the air flow X sent from the rear end portion of the main exhaust passage 70 to the rear side exhaust passage 75 rises along the rear side exhaust passage 75 and is exhausted from the rear exhaust port 23 to the outside of the main body housing 10. The

  Since the air flow X exhausted from the rear exhaust port 23 is exhausted through a long exhaust passage formed by the main exhaust passage 70 and the rear exhaust passage 75, the flow velocity is reduced and the exhaust noise is reduced. . Moreover, since it exhausts through a long exhaust passage, the noise of the air blower 41 transmitted through this exhaust passage is also reduced.

  On the other hand, the upper end of the rear-side exhaust passage 75 communicates with an ion generation chamber 90 formed in the upper portion of the blower chamber 40. For this reason, a part of the air flow X sent to the back side exhaust passage 75 is sent to the ion generation chamber 90. Since the ion generation section 91 is provided in the ion generation chamber 90, the air flow X sent into the ion generation chamber 90 includes ions and is exhausted from the ion discharge port 24. Of course, the airflow X exhausted from the ion exhaust port 24 also has reduced exhaust sound.

  The rear end portion of the main exhaust passage 70 also communicates with the cord reel chamber 50 through the opening 72. Therefore, the airflow X sent to the lower end portion of the cord reel chamber 50 cools the cord reel 51 while ascending the cord reel chamber 50, and is exhausted from the cord outlet 25 provided in the upper portion of the cord reel chamber 50. .

  As shown in FIG. 9, the rear end portion or the rear side exhaust passage 75 of the main exhaust passage 70 communicates with the bumper 26 through an opening (not shown) opened in the inner wall of the main body housing 10. An opening (not shown) that communicates with the bumper 26 is also formed on the inner wall of the cord reel chamber 50. A bumper exhaust passage 85 as shown in FIG. 8 is formed in the bumper 26. Therefore, the airflow X sent to the rear end portions on both sides of the bumper 26 is sent forward from the rear end portion of the bumper exhaust passage 85 and is exhausted from the bumper exhaust port 27. The air flow exhausted from the bumper exhaust port 27 also has reduced exhaust sound.

  As described above, the exhaust passage according to this embodiment has a different exhaust passage between the front exhaust passage from the hose attachment portion 21 to the blower 41 and the rear exhaust passage exhausted from the blower 41 to the outside of the main body housing 10. Forming. That is, the front exhaust passage that extends from the hose attachment portion 21 through the dust collection case 100 to the blower chamber 40 is an exhaust passage that gently extends from the front to the rear, and is therefore a passage with a small suction loss of the blower 41. On the other hand, the rear exhaust passage is largely turned up in the blower chamber 40 and sent to the front filter chamber 60, and is further turned up in the filter chamber 60 and dispersedly exhausted from the rear end portion of the main exhaust passage 70. In addition, the airflow X that is distributed and exhausted is exhausted out of the main body housing 10 through longer exhaust passages such as the back side exhaust passage 75, the cord reel exhaust passage 80, or the bumper exhaust passage 85, so that noise is reduced. Can be reduced. Further, since the airflow X exhausted outside the main body casing 10 is exhausted from the periphery of the main body casing 10 at a high position of the main body casing 10, the exhaust strikes the floor surface and dust on the floor surface is discharged. It is possible to mitigate or prevent direct exhaust from hitting the user.

  Next, a specific structure of the operation state display unit 47 will be described in detail with reference to FIGS. Here, FIG. 10A is an E sectional view of FIG. 4, and FIG. 10B is an external perspective view of the dust collecting case mounting portion.

  In FIG. 1, in this embodiment, the dust collection case 100 is disposed in a posture inclined obliquely rearward, so that the front inclined surface 151 that supports the bottom surface of the dust collection case 100 is an inclined surface with the front rising. And the recessed part 155 which arrange | positions the air inflow port 152 in the recessed position is formed in the center of this front part inclined surface 151. As shown in FIG. Therefore, a dead space is created around the recess 155.

  In this embodiment, by arranging the filter chamber 60 below the rear inclined surface 153, a space having a substantially triangular shape as viewed from the side surface is effectively used. However, it is impossible to use the tip portion having a substantially triangular space narrowed for the filter chamber 60. Therefore, in this embodiment, the space is effectively utilized by providing the state display part substrate 48 at the tip of the substantially triangular shape. Moreover, since the tip of the substantially triangular shape is close to the control board 46 disposed in the main exhaust passage 70, wiring and assembling can be improved.

  10 and 11, in this embodiment, the operation state display unit 47 is formed in a transparent resin ring shape with the rear side cut off. A reflection member (not shown) is formed on the bottom surface of the operation state display unit 47. Then, the operation state display unit 47 is embedded in the front inclined surface 151 around the recess 155. In addition, a light emission source 49 is disposed at each of the pair of cut ends at the rear of the operation state display unit 47, and the light of the light emission source 49 is irradiated from the cut ends.

  According to this structure, the light emitted to the ring-shaped operation state display unit 47 is transmitted along the ring shape through the entire operation state display unit 47, and the transmitted light is guided upward by the reflecting member. It is burned.

  On the other hand, in this embodiment, the first case 110 installed on the front inclined surface 151 is formed of a transparent resin material. Therefore, the ring-shaped light emitted from the driving state display unit 47 enters the first case 110 from the cylindrical bottom surface. And the light which entered this 1st case 110 can be reflected in the thickness of a transparent part, or the connection cover 113, and can obtain the effect which shines the 1st case 110 whole.

  Moreover, since the illuminance of the light emission source 49 changes in accordance with the load of the blower 41, the state display unit substrate 48 illuminates the entire ring-shaped operating state display unit 47 or the ring. Only both sides of the shape shine or change. Therefore, the user can recognize the operation state of the vacuum cleaner main body 1 by the change visually enhanced by the first case 110. In this embodiment, the light emission source 49 may be composed of a single color LED, or may be composed of a multicolor LED or a plurality of LEDs having different colors.
