Further, when the usage state shown in FIG. 9 is changed to the storage state shown in FIG. 8, first, the plug portion 17 of the cord 15 pulled out from the cord opening 18 of the motor case portion 14 of the cleaner body 12 is removed. Pull out from the outlet.

Next, the cord take-up button 19 of the motor case portion 14 is pressed to rotate the cord reel portion 16 of the motor case portion 14, and the cord 15 pulled out by the cord reel portion 16 is taken up.

After that, the clamp operation button 26 of the handle body 23 is pushed to push the claw portion of the clamp portion 24 of the handle body 23.
In a state where the air passage case portion 21 is disengaged from the clamp receiving portion 25 by 27, the handle body 23 is rotated and bent toward the rear side of the air passage case portion 21.

Then, the handle portion 22 of the cleaner body 12 is gripped, and the cleaner body 12 is carried to the accommodation place and accommodated therein.

Next, the assembling operation of the above embodiment will be described.

First, the intake pipe 48 is fitted into the exhaust air passage 41 of the one air passage case portion 21 formed in the left-right direction, and the outlet port 49 of the intake pipe 48 is attached to the air passage 41 using the packing 52. The main body intake port 46 of the intake pipe 48 is connected to the intake communication port 51 of the case part 21 in an airtight manner, and the circulation exhaust port of the air passage case part 21 is connected.
42 concentric communication.

At this time, the fitting projection 121 of the intake pipe 48 is fitted into the fitting receiving portion 122 of the air duct case 21, and
The fitting convex portion 125 of the intake pipe 48 is fitted into the fitted portion of the air passage case portion 21, and the fitting groove portion 126 of the fitting portion 127 of the intake pipe 48 is formed into the rib of the air passage case portion 21. The part 128 is fitted.

In this state, similarly, the other air passage case portion 21 is fitted with the fitting receiving portion 122, the fitted portion and the rib portion 128 of the air passage case portion 21, respectively. The 121, the fitting convex portion 125, and the fitting portion 127 are fitted to each other to combine the one air passage case portion 21 and the other air passage case portion 21.

Thereafter, a screw body is inserted into the screw insertion hole 124 of the mounting piece 123 of the intake pipe 48, and the mounting piece 123 is screwed and fixed to the airway case 21. Department
A separate intake pipe 48 is positioned and fixed in the exhaust air passage 41 of 21, and the intake air passage 47 in the intake pipe 48 is positioned concentrically in the exhaust air passage 41.

As described above, according to the above-described embodiment, the lid body of the dust collecting cup 84 is in a state in which the respective engaging convex portions 191 of the lid body 104 are engaged with the cut groove concave portions 178 of the cyclone portion 103. By picking the knob portion 192 of 104 and taking out the air passage control body 101 from the cup portion 85 of the dust collecting cup 84, the cup portion 85
Therefore, the cyclone unit 103, the swivel lid unit 181, and the auxiliary filter 195 can be integrally removed together with the lid body 104.

Therefore, by inclining the cup portion 85 or the like in this state, the cyclone portion 103, the swirl lid portion 181, the auxiliary filter 195, and the lid body 1 which constitute the wind direction control body 101.
Cup part 85 of dust collecting cup 84 without disassembling 04
The dust collected inside the can be taken out,
The dust collected in the dust collecting cup 84 can be taken out without unnecessarily soiling the hands and the like.

On the other hand, it is not necessary to take out the dust accumulated in the cup portion 85 of the dust collecting cup 84, and the inside of the mesh body 107 of the lid 104 of the dust collecting cup 84, the auxiliary filter 195 and the cyclone portion 103 are cleaned. If desired, the knob 192 of the lid 104 of the dust collecting cup 84 is picked, the lid 104 is rotated with respect to the cyclone 103, and the cyclone 1
By releasing the engagement of the engaging protrusion 191 of the lid 104 with the cut groove recess 178 of 03, only the lid 104 can be removed from the dust collecting cup 84.

That is, from the dust collecting cup 84 to the lid 104
By removing the lid body 104 and the lid body 1
Since the auxiliary filter 195 attached between the 04 and the swirl lid 181 can be cleaned, the dust captured by the mesh body 107 of the lid 104 can be removed and the auxiliary filter 19
The dust captured in 5 can be removed.

Furthermore, by removing the swirling lid portion 181 from the cyclone portion 103 from which the lid body 104 has been removed, the inside of the cyclone portion 103 is opened, so that dust accumulated between the cyclone portion 103 and the swirling lid portion 181. Can be easily taken out, and the inside of the cyclone unit 103 can be easily cleaned.

As a result, by disassembling a desired portion of the dust collecting cup 84 according to the purpose of cleaning the dust collecting cup 84, the dust collecting cup 84 is not complicatedly disassembled. Since the desired portion of 84 can be easily and surely cleaned, the usability of this dust collecting cup 84 can be improved.

Then, the suction wind sucked from the suction port 117 of the floor brush 111 by the suction of the electric blower 13 causes the dust collecting cup 84
The dust that is swirled in the cyclone 103 of the above and sucked in together with this suction wind falls due to its own weight and is collected inside the cup portion 85 of the dust collection cup 84, and the suction wind that has passed through this dust collection cup 84 After being exhausted by the electric blower 13, the floor brush 11 is passed through the exhaust air passage 41 of the air passage case portion 21.
The air is exhausted from the circulating air exhaust port 1 and circulates to the suction port 117 of the floor brush 111.

Therefore, the suction air is swirled, and the dust sucked together with the suction wind is separated by its own weight to separate the dust. The so-called cyclone type dust collecting cup 84 collects the sucked dust. For example, the collected dust is less likely to cause ventilation resistance as compared with an electric vacuum cleaner in which the suction air is sucked into the paper pack and the dust sucked together with the suction air is captured by the paper pack.

Therefore, the cleaner body having the so-called circulation type intake air passage 47 and exhaust air passage 41 for circulating the exhaust air.
The circulation amount of the suctioned air by the electric blower 13 in the motor case portion 12 of 12 is less likely to decrease. As a result, it is possible to prevent a decrease in the circulation efficiency of the suction air by the electric blower 13, and thus it is possible to prevent a decrease in the amount of circulation air circulated in the floor brush 111. Therefore, the advantages of the circulation type, for example, it is possible to prevent the floor brush 111 from sticking to the floor surface, and to prevent the dust releasing action on the floor surface due to the circulating wind from decreasing, so the cleaning efficiency of the circulation type vacuum cleaner 11 Can be prevented.

In addition, an inlet 91 for sucking the intake air sucked into the intake air passage 47 of the air passage case portion 21 into the inside of the dust collecting cup 84 is provided at the opening of the cup portion 85 of the dust collecting cup 84. Since it is provided on the peripheral surface portion 86 on the 87 side, the suction air is taken in from the side of the cup portion 85. Therefore, the suction air sucked into the cup portion 85 can be easily and efficiently swirled inside the cup portion 85 to generate swirling wind.

Furthermore, since the inflow port 91 of the cup portion 85 is opened to the peripheral surface portion 86, the length of the intake air passage 47 in the air passage case portion 21, that is, the length of the intake pipe 48 can be shortened. Therefore, even if the intake pipe 48 has a double-pipe structure in which the intake air passage 47 is formed in the air passage case portion 21, exhaust air is exhausted by the intake pipe 48 as compared with the case where the inlet is formed in the upper opening of the cup portion. Since the length of the part where the cross section of the path 41 becomes small can be shortened,
The air passage resistance in the exhaust air passage 41 can be reduced, and the circulation efficiency can be improved.

The connecting portion 113 to which the base end portion of the connecting pipe 112 of the floor brush 111 is detachably connected generally needs to form a connecting mechanism such as a clamp, so that it is generally complicated. It will be composed. Therefore, this connecting portion 113 is located at the lower end side of the bottom portion 88 of the dust collecting cup 84, that is, the air passage case portion 21.
It is installed at the lower end of the
The connecting portion 113 can be widened in the radial direction by forming the peripheral surface portion 86 into a tapered shape in which the diameter is gradually reduced from the opening portion 87 side toward the bottom portion 88 side.

Therefore, the intake air passage 4 in the connecting portion 113 is
By increasing the outer diameter of the connecting portion 113 without reducing the cross-sectional area of the exhaust passage 41 and the exhaust air passage 41, the entire electric vacuum cleaner 11 including the air passage case portion 21 and the dust collecting cup 84 is enlarged. Without increasing, it is not necessary to increase the air passage resistance in each of the intake air passage 47 and the exhaust air passage 41 in the connection portion 113. Therefore, since it is possible to prevent the intake air amount 47 and the exhaust air passage 41 in the connecting portion 113 from reducing the intake air amount and the exhaust air amount of the electric blower 13, it is possible to further prevent the cleaning efficiency of the electric blower 13 from decreasing.

At this time, the peripheral surface portion 86 of the dust collecting cup 84 is moved from the opening 87 side to the bottom portion according to the external shape of the air duct case portion 21.
Since the diameter is reduced toward the 88 side, the dust collecting space by the cup portion 85 of the dust collecting cup 84 can be further secured.

Further, the peripheral surface portion 86 of the cup portion 85 of the dust collecting cup 84 is tapered so that the diameter gradually decreases from the opening portion 87 side toward the bottom portion 88 side. The centrifugal force for directing dust on the bottom portion 88 side in 85 toward the outside is larger than that on the opening 87 side in the cup portion 85. Therefore, the bottom portion 88 in the cup portion 85 is
On the side, since dust is less likely to collect in the center, the dust in the cup portion 85 can be more reliably separated.

Further, the intake air passage 47 and the exhaust air passage 41 are defined by ribs along the longitudinal direction in the air passage case portion 21 without forming the double pipe structure, and the intake air passage 47 is covered with the dust collecting cup 84. By bringing the intake air passage 47 into communication with the inflow port 91 of the dust collecting cup 84, the exhaust air passage by the intake air passage 47
It is possible to reduce the obstruction of 41 and shorten the length of the intake air passage 47. For this reason, it is possible to further prevent an increase in the air passage resistance in the exhaust air passage 41 and to simplify the structures of the intake air passage 47 and the exhaust air passage 41, so that the structure of the air passage case portion 21 is simplified. The productivity of the cleaner body 12 can be improved.

Further, the electric blower 13 and the dust collecting cup 84 are arranged on the side of the air duct case portion 21, and the intake air duct 47 and the exhaust gas on the lower end side of the dust cup 84 in the air duct case portion 21 are arranged. By making the air passage 41 and the double pipe structure,
These intake air passages 47 on the lower end side of the dust cup 84
Also, the strength of the exhaust air passage 41 is improved, and the strength of the air passage case portion 21 on the lower end side of the dust cup 84 is improved. Therefore, by supporting the comparatively heavy electric blower 13 and the dust collecting cup 84 with the air passage case portion 21 on the lower end side of the dust cup 84 having the improved strength, the electric blower 13 and the dust collecting dust by the cleaner body 12 are supported. Since the cup 84 can be supported more reliably, the strength of the cleaner body 12 can be more reliably ensured.

Further, since the opening 87 of the dust collecting cup 84 is communicated with the suction side of the electric blower 13 via the inducer 75, the air passage on the suction side from the dust collecting cup 84 to the electric blower 13 is formed. The configuration is simplified. Therefore, the suction force of the electric blower 13 can be easily ensured, and the cleaning efficiency of the electric blower 13 can be more easily ensured.

Furthermore, an upright type vacuum cleaner
By dividing the air passage case part 21 of 11 in the left and right direction,
Since the intake pipe 48 positioned and fixed in the exhaust air passage 41 of the air passage case portion 21 can be detachably attached, the intake pipe 48 whose design is changed, such as the cross-sectional area and wall thickness of the intake air passage 47, By changing the design of the air passage case portion 21 by installing it in the exhaust air passage 41 of the air passage case portion 21 as compared with an electric vacuum cleaner in which the exhaust air passage and the intake air passage are configured by the same intake pipe. Without changing the design of only the intake pipe 48, the air duct case part
The cross-sectional area of each of the exhaust air passage 41 and the intake air passage 47 in 21 can be easily changed.

Therefore, the exhaust air passage 41 of this air passage case portion 21.
By changing the design of the intake pipe 48 installed inside and changing the cross-sectional area and wall thickness of the intake air passage 47 of this intake pipe 48, the recirculation rate by the intake air passage 47 and the exhaust air passage 41 can be easily changed. In addition, it is possible to easily manufacture the intake air passage 47 and the exhaust air passage 41 corresponding to the change in the output of the electric blower 13 having different work efficiencies. It can be easily manufactured.

In addition, the upright type electric vacuum cleaner 11 is
In general, the distance between the dust collecting cup 84 and the floor brush 111 is often short, so the intake air path 47 between the dust collecting cup 84 and the floor brush 111 and the intake air forming the inner surface of the exhaust air path 41 are formed. By replacing the pipe 48, it is possible to more easily make a design change according to the suction efficiency of the electric blower 13 and the circulation efficiency due to the cross-sectional areas of the intake air passage 47 and the exhaust air passage 41.

Further, when the branch intake port 56, which is connected to one end in the longitudinal direction of the hose body 61, is provided near the main intake port 46 of the intake pipe 48, the branch intake port 56 is connected to the main intake port 46. The connecting pipe 112 of the floor brush 111 to be formed must also have an opening (not shown) communicating with the branch intake port 56, and the opening of this connecting pipe 112 is connected to the branch intake port 5 of the intake pipe 48.
When connecting to 6, the connecting pipe 112 of the floor brush 111 is connected to the intake pipe 48.
Must be aligned and connected in the circumferential direction.

Therefore, by providing the branch intake port 56 at an intermediate portion of the intake pipe 48 in the axial direction of the main body intake port 46, the main pipe intake port 46 of the intake pipe 48 communicates with the connection pipe 112 of the floor brush 111. Since the connecting mechanism can be made easy, the productivity of the electric vacuum cleaner 11 can be improved, and since the branch intake port 56 is located above the cleaner body 12, the hose body 61 connected to the branch intake port 56 can be improved. This makes it easier to clean high places such as shelves.

Furthermore, in order to efficiently separate the dust drifting in the suction air in the cup portion 85 of the dust collecting cup 84 by its own weight, the wind speed of the suction air in the cup portion 85 needs to be increased to some extent. There is an inlet 91 of this cup 85
The intake air passage 47 in the intake pipe 48 that air-tightly communicates with the main body intake port 46 is smoothly reduced in size as it goes in the intake direction of the intake air passage 47.
The wind velocity of the suction wind passing through the inside gradually increases as it passes through the intake air passage 47.

Therefore, it is not necessary to increase the suction force of the electric blower 13 to some extent by increasing the power supplied to the electric blower 13 or the like, so that the suction force of the electric blower 13 is lowered to some extent. Is possible,
It is possible to reduce power consumption, heat generation, and the like due to the electric blower 13.

Furthermore, even if the suction force of the electric blower 13 is reduced to some extent, the wind speed of the suction wind sucked into the cup 85 of the dust collecting cup 84 can be ensured at a predetermined speed in the cup portion 85. It is possible to more easily secure the wind speed of the suction air inside the cup portion 85.

Further, by smoothly changing the cross-sectional area of the intake air passage 47 of the intake pipe 48 to a small value,
Since the pressure loss of the intake air passing through the air intake passage 47 is reduced, the decrease in intake efficiency due to the intake air passing through the intake air passage 47 can be reduced, so that the wind speed of the intake air passing through the intake air passage 47 can be made more efficient. You can accelerate.

Furthermore, the fan cover of the electric blower 13
Inlet 132 of 131 and opening 87 of cup part 85 of dust collecting cup 84
A leak valve mounting cylinder portion 79 is integrally formed on the outer surface of the frame portion 134 of the inducer 75 for maintaining airtight communication with A leak valve 81 is installed to prevent the leak valve 81 from communicating with the suction side of the electric blower 13 through the leak valve mounting cylinder 79.Therefore, any part of the suction side of the inducer 75 is clogged. Even if the leak valve
With the leak of 81, the suction side of the electric blower 13 can communicate with the outside air.

For this reason, the load on the electric blower 13 generated when the air pressure on the suction side of the electric blower 13 is extremely lowered to a so-called negative pressure, for example, rectification by heat radiation generated while the electric blower 13 is driven. Since the child can be prevented from being damaged, the electric blower 13 can be protected more reliably.

Further, the leak valve mounting cylinder portion 79 is integrally connected to the outer surface of the frame portion 134 of the inducer 75, and the leak valve mounting recess 141 of the leak valve mounting cylinder portion 79 is connected to the lattice portion 136 of the inducer 75. On the exhaust side of this inducer 75 rectifier 135
Since the exhaust side of the frame portion 134 of the inducer 75 is airtightly communicated with the intake port 132 of the fan cover 131 of the electric blower 13, the leak valve mounting recessed portion 141 of the leak valve mounting tubular portion 79 can be connected. The leak valve 81 fitted can be communicated with the suction side of the electric blower 13, and the leak valve mounting cylinder 79
It is possible to surely prevent intake air leakage from the leak valve mounting recess 141 of the electric fan 13.
Since many members etc. are not needed when attaching,
Since the structure for attaching the leak valve 81 to the suction side of the electric blower 13 is simple, the leak valve 81 can be easily attached to the suction side of the electric blower 13.

Further, the filter body 77 is attached to the suction side of the lattice portion 136 of the inducer 75, and the leak valve attachment recess 141 of the leak valve attachment cylinder portion 79 is attached to the inducer 75 on the exhaust side of the lattice portion 136 of the inducer 75. Since it is connected to the rectification port 135 of, even if this filter body 77 is clogged,
Since the leak valve 81 fitted in the leak valve mounting recess 141 of the leak valve mounting tubular portion 79 leaks surely, the electric blower 13 can be protected more reliably.

Further, since the leak valve 81 is arranged at a position across the exhaust air passage 41 of the air passage case portion 21 with respect to the motor case portion 14, the space for mounting the leak valve 81 can be effectively utilized. .

Furthermore, the engagement of the dust collecting cup 84 with the engaging edge portion 166 of the cyclone portion 103 to the suction side of the frame portion 134 of the inducer 75 of the motor case portion 14 is performed by the dust collecting cup 84.
The engaging claw portion 95 of the clamp portion 93 engages with the engaging protrusion 98 of the engagement receiving portion 96 of the air passage case portion 21 to position and fix the wind, and the wind by the engaging claw portion 95 of the dust collecting cup 84. The engagement of the road case portion 21 with the engagement protrusion 98 can be released by pressing the cup removal button 99.

Therefore, in general, when grasping the cup portion 85 of the dust collecting cup 84 which is easy to grasp by hand, it is not in the rear direction of the cleaner body 12 in which the air duct case portion 21 is located, that is, the cleaner body 12 From the front of this dust collecting cup 84 cup portion 85
Is to grab.

Therefore, when the dust removing cup 84 is attached to the cleaner body 12, the cup removing button 99 is located on the right side of the cleaner body 12 in the traveling direction. Since it is provided on the right side surface of the 85, the cup removal button 99 can be pressed with the thumb of the right hand when the cup 85 of the dust collecting cup 84 is grasped with the right hand from the front side facing the air duct case 21. This dust collection cup 84
When the cup portion 85 is gripped by the left hand from the front side facing the air duct case portion 21, the cup removal button 99 can be pushed by the index finger or the like of the left hand.

Therefore, as compared with the case where the cup removing button 99 is provided on the front side of the outer surface of the dust collecting cup 84, the dust collecting cup 84 is operated as a series of operations for gripping the dust collecting cup 84.
Since the operation of removing 84 from the cleaner body 12 can be performed, the operation of removing the dust collecting cup 84 from the cleaner body 12 can be made easier.

Further, the engagement edge 166 of the cyclone portion 103 located at the upper end portion of the dust collecting cup 84 surely fixes and supports the engagement of the frame portion 134 of the inducer 75 of the motor case portion 14 with the suction side. In order to do this, the engaging edge of this dust collecting cup 84
The bottom portion 88, which is the lower end portion of the dust collecting cup 84 facing the 166.
Further, it is desirable to provide a mechanism for fixing the engagement of the frame portion 134 of the inducer 75 by the engagement edge portion 166 of the dust collecting cup 84.

Further, the engaging edge portion 166 of the dust collecting cup 84.
The mechanism for releasing the engagement and fixing of the frame portion 134 of the inducer 75 by the fixing means fixes the engagement of the frame portion 134 of the inducer 75 by the engagement edge portion 166 of the dust collecting cup 84. It is desirable to install it in a place close to the mechanism.

Therefore, the clamp portion 93 for fixing the engagement of the frame portion 134 of the inducer 75 of the motor case portion 14 by the engagement edge portion 166 of the cyclone portion 103 on the upper side of the dust collecting cup 84, and the clamp portion 93. The bottom of the cup portion 85 of the dust collecting cup 84, which is on the opposite side of the engaging edge portion 166 of the cyclone portion 103 of the dust collecting cup 84, from the cup removing button 99 that releases the engagement and fixing by the clamp portion 93 Since it is provided at 88, the dust collecting cup 84 can be reliably supported by the cleaner body 12 in the vertical direction and attached to the cleaner body 12.

Further, since each of the clamp portion 93 and the cup removing button 99 is provided on the bottom portion 88 of the cup portion 85 of the dust collecting cup 84, the distance between the clamp portion 93 and the cup removing button 99 becomes short. . Therefore, since the clamp portion 93 and the cup removal button 99 can be integrally formed as the same member, the structure of the dust collecting cup 84 can be simplified and the manufacturability of the dust collecting cup 84 can be improved.
