FIG. 1 is a perspective view showing a state where the electric vacuum cleaner according to the present embodiment is stored in a support base.

As shown in FIG. 1, the electric vacuum cleaner 100 can be cleaned by changing to various usage patterns such as a handy state and a stick state. The support base 70 in which the vacuum cleaner 100 is housed is a room in which the vacuum cleaner 100 is connected in a stick state in which the extension pipe 300 (accessory) and the standard suction port 400 (accessory) are connected. And a section 72. Further, the vacuum cleaner 100 can be used by connecting a small suction port (accessory), a broom suction port (accessory), an extension hose (accessory), etc., which are not shown. The standard suction port 400 is a power brush type in which a brush is rotated by a motor.

FIG. 2 is an exploded view of the electric vacuum cleaner according to the present embodiment. In the drawings below FIG. 2, the front, rear, left, right, up, and down directions as viewed from the cleaner body 1 are appropriately shown.

As shown in FIG. 2, the electric vacuum cleaner 100 includes a cleaner body 1, a dust case 2 (dust collecting device), a storage battery 3, and an airtight holding member 90.

The cleaner body 1 includes a body portion 10, a motor case portion 11, and a handle portion 12.

The main body 10 is formed with a connection port 10a (suction port) to which the extension pipe 300, the standard suction port 400 (see FIG. 1), etc. are connected. The connection port 10a is made of the same resin as the main body 10, the motor case 11, the handle 12 and the like. Further, the connection port 10a has a substantially circular opening and is formed facing forward. The connection port 10a includes accessories such as the extension pipe 300, the standard suction port 400, a small suction port (not shown), and a broom type suction port (not shown) as accessories (hereinafter, collectively referred to as an attachment. ) Can be connected. The connection port 10a has a built-in terminal (not shown) electrically connected to the circuit board 50 (see FIG. 6), and when a motor driving accessory such as the standard suction port 400 is connected, , Electrically connected to rotate the brush by the motor.

Further, the main body 10 is detachably attached to the dust case 2, and is provided with an introduction pipe 14 (see FIG. 3) for feeding the dust-containing air sucked from the connection port 10a into the dust case 2.

The motor case portion 11 includes an electric blower 40 (see FIG. 6) and a circuit board 50 (see FIG. 6). In addition, a circular suction port (not shown) is formed on the front surface of the motor case portion 11 for sucking clean air that has been collected by the dust case 2.
The handle portion 12 is provided on the rear side of the main body portion 10 and has a grip portion 12a formed in a substantially L shape. The gripping portion 12a has a first gripping portion 12a1 that linearly extends so as to be gradually higher toward the rear side in the front-rear direction, and a second gripping portion 12a2 that linearly extends in the substantially vertical direction. Further, in the grip portion 12a, the second grip portion 12a2 extends substantially downward from the rear end of the first grip portion 12a1. The first grip portion 12a1 is located on the front side of the second grip portion 12a2. The second grip portion 12a2 is slightly inclined with respect to the vertical direction such that the upper portion thereof faces forward. In addition, the first grip portion 12a1 and the second grip portion 12a2 are substantially rod-shaped and continuously formed. As described above, by configuring the first grip portion 12a1 and the second grip portion 12a2 to be linear, it becomes easier for the user to recognize the position of the handle. Further, since the first grip portion 12a1 and the second grip portion 12a2 are connected so as to be bent at an angle close to a right angle, when the first grip portion 12a1 is gripped, the second grip portion 12a2 is operated toward the second grip portion 12a2. Is difficult to shift, and conversely, when holding the second grip portion 12a2, the hand is hard to shift toward the first grip portion 12a1.

The first grip portion 12a1 extends in the front-rear direction so as to gradually become higher toward the rear side. Therefore, it is easy to put a hand in the gap 12c (see FIG. 6).

Further, an operation button 12b is provided on the upper surface of the first grip portion 12a1 of the handle portion 12. The operation button 12b is composed of, for example, three buttons, "strong", "standard", and "off".

Release buttons 18a and 18b that are operated when removing accessories such as the extension pipe 300 are provided on the upper front end and the upper rear of the main body 10. By pushing down the release buttons 18a and 18b, the lock between the main body 10 and the accessory is released, and the accessory can be removed from the main body 10. The mechanism of the release buttons 18a and 18b will be described later.

Further, an airtight holding member 90 can be attached to the front end of the main body 10. The airtight holding member 90 has a substantially circular tubular body 91. The cylindrical body 91 has an elastic portion 91a formed of a soft resin in an annular shape on the tip side. The tubular body 91 has a connecting portion 91b formed on the base end side thereof, which is made of a material harder than the elastic portion 91a and is connectable to the main body portion 10. The tubular body 91 is configured by integrally molding two different kinds of members, that is, the elastic portion 91a and the connecting portion 91b. The elastic portion 91a is made of an elastically deformable (flexible and deformable) material such as an elastomer. By attaching such an airtight holding member 90 to the connection port 10a of the cleaner body 1, the entire tip 90s of the airtight holding member 90 can be brought into close contact with the floor surface, and the suction force is improved as compared to the case where the airtight holding member 90 is not in close contact. Can be made. Further, by forming the connecting portion 91b with a hard material, the airtight holding member 90 can be attached to the main body portion 10 in a stable state without dropping.

In the present embodiment, the case where the elastic portion 91a is made of an elastic material such as elastomer has been described as an example, but the present invention is not limited to this. For example, substantially the entire tubular body 91 may be formed of the same material as that of the connecting portion 91b, and the tip of the tubular body 91 may be provided with a ring of short bristles that are electrostatically planted. Even if the electrostatic flocking is provided, the tip of the airtight holding member 90 can be brought into close contact with the floor surface like the elastomer, and the suction force can be improved.

An elongated fitting groove 10b is formed in the vertical direction on the outer surface of the connection port 10a of the main body 10. The fitting groove 10b is formed on each of the left and right sides. A protrusion (not shown) is formed at the base end of the connecting portion 91b so as to be engaged with the fitting groove 10b in a concavo-convex manner and locked.

In addition, the main body 10 may be provided with a light emitting element above the connection port 10a.

The storage battery 3 supplies electric power to the electric motor 40a (see FIG. 6) of the electric blower 40 that generates a suction force, and is composed of a secondary battery such as lithium ion or nickel hydrogen. Further, the storage battery 3 has a substantially semi-cylindrical case 3a made of synthetic resin, and can be attached to and detached from the main body 10 by sliding the case 3a in the front-back direction.

FIG. 3 is a side view of the electric vacuum cleaner 100 in the state of FIG. 2 viewed from the left side.

As shown in FIG. 3, the dust case 2 is of a cyclone type and has a function of separating air containing dust sucked from the introduction pipe 14 into dust and air and collecting the dust. Further, the dust case 2 is arranged in front of the motor case portion 11 with its axial direction in the front-rear direction, and has a substantially cylindrical storage portion 2a. Further, a substantially rectangular inflow port 2b (see FIG. 2) connected to the introduction pipe 14 is formed on the upper surface (side surface) of the dust case 2. The air containing dust that has flowed into the inflow port 2b becomes a swirling flow, centrifugal force acts on the dust, and after the dust and air are separated in the dust case 2, the air from which the dust is separated is the dust case. 2 is discharged from the rear part (rear surface).

A lid 2c that opens and closes when the dust collected in the dust case 2 is discarded is rotatably supported on the front surface of the dust case 2 via a hinge portion 2d. A lid lock mechanism 2e for unlocking the lid 2c is provided on the lid 2c. The internal mechanism of the dust case 2 can be configured based on JP-A-2016-137165.

FIG. 4 is a perspective view of the electric vacuum cleaner according to the present embodiment.

As shown in FIG. 4, in the electric vacuum cleaner 100, the dust case 2 is attached below the main body 10 and in front of the motor case 11. In this case, when the dust case 2 is attached to the cleaner body 1, the lid lock mechanism 2e is hidden on the cleaner body 1 side. This is because if the lid lock mechanism 2e is provided on the opposite side (outside), the lid lock mechanism 2e may be released during cleaning. However, by making the lid lock mechanism 2e hidden on the cleaner body 1 side, malfunction can be prevented. For example, when cleaning the sofa or the bottom of a bed in a stick state, the cleaner body 1 may be brought close to the floor surface horizontally. At this time, when the lid lock mechanism 2e is provided on the front side, there is a possibility that the lid lock mechanism 2e may be released by coming into contact with the floor surface. The positions of the lid lock mechanism 2e and the hinge portion 2d are not limited to this, and they may be provided on the left and right sides of the cleaner body 1.

A cleaning brush 2s (see FIGS. 2 and 3) is detachably provided in the dust case 2. The cleaning brush 2s is arranged at a position that is difficult to see from the outside when the dust case 2 is attached to the cleaner body 1. For this reason, it is difficult for the cleaning brush 2s to come off during operation, and it is not necessary to store the cleaning brush 2s in a place different from the vacuum cleaner 100.

FIG. 5 is a plan view of the electric vacuum cleaner according to the present embodiment.

As shown in FIG. 5, the connecting portion 91b of the airtight holding member 90 is formed with extending portions 91b1 and 91b1 extending rearward on both left and right sides. A concave portion 91b2 is formed between the left extension portion 91b1 and the right extension portion 91b1 in a plan view. The concave portion 91b2 fits with the front end portion 10d1 of the protruding portion 10d formed on the top surface of the tip of the main body portion 10. As a result, the airtight holding member 90 is positioned in the front-rear direction and the left-right direction with respect to the connection port 10a (see FIG. 2).

The introduction pipe 14 formed in the main body 10 is formed so as to extend obliquely rearward to the right and then downward, and is connected to the inflow port 2b (see FIG. 2) of the dust case 2. As a result, a swirling flow can be generated in the housing portion 2a of the dust case 2, and the dust can be effectively separated by the centrifugal force.

6 is a sectional view taken along line VI-VI of FIG. As shown in FIG. 6, an electric blower 40 is housed in the motor case portion 11 of the main body portion 10. The electric blower 40 is driven by the electric motor 40a. A circuit board 50 (circuit board) that controls the cleaner body 1 is housed in the motor case 11 above the electric blower 40.

The electric blower 40 and the circuit board 50 are arranged so as to overlap each other in the vertical direction. Therefore, the dimension of the cleaner body 1 in the front-rear direction can be shortened. Further, in the electric blower 40, since the motor case portion 11 is formed to bulge toward the handle portion 12 side, the dimension of the body portion 10 in the front-rear direction (total length) can be shortened.

The electric blower 40 and the circuit board 50 are located below the first grip portion 12a1 of the handle portion 12. Accordingly, when the user grips and operates the first grip portion 12a1, the center of gravity of the electric vacuum cleaner 100 is near the lower portion of the first grip portion 12a1. Therefore, when the tip of the electric vacuum cleaner 100 is used facing upward, the electric vacuum cleaner 100 can be stably held.

A gap 12c for inserting a hand is formed between the first grip portion 12a1 and the upper surface 11c of the motor case portion 11. A gap 12d is formed between the second grip portion 12a2 and the back surface 11d of the motor case portion 11.

The thickness T1 of the first grip portion 12a1 is thin, and the thickness T2 of the second grip portion 12a2 is thicker than the thickness T1. That is, the first grip portion 12a1 is thin and the second grip portion 12a2 is thick. As described above, when the second grip portion 12a2 is gripped and cleaned, by increasing the thickness T2 of the second grip portion 12a2, it becomes easier to grip deeply and the strength of the second grip portion 12a2 can be increased. it can.

The storage battery 3 can be composed of, for example, a lithium ion battery having high energy efficiency. The storage battery 3 is arranged below the second grip portion 12a2 of the handle portion 12. As described above, by providing the storage battery 3 at the rear end of the electric vacuum cleaner 100, the center of gravity of the handle portion 12 becomes closer to the second gripping portion 12a2. Can be lightened.

The airtight holding member 90 is formed so as to be substantially parallel to the cleaning surface when the second end 12a2 is ended, and the tip (tip surface) 90s is inclined so as to recede from the upper part to the lower part. There is. The dust case 2 is located rearward of the surface R2 passing through the tip 90s. Thereby, even when the tip 90s of the airtight holding member 90 is brought into contact with the floor surface such as the flooring, the dust case 2 can be prevented from hitting the floor surface.

A filter 5 is housed in the dust case 2 at the axially rear end of the housing 2a. The filter 5 is formed by folding it into pleats, and can increase the filter area and reduce the pressure loss due to the filter 5.

The filter 5 is composed of, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter). The HEPA filter is an air filter that has a particle collection rate of 99.97% or more for particles having a particle size of 0.3 μm at the rated air volume and an initial pressure loss of 245 Pa or less.

As shown in FIG. 6, the dust case 2, the electric motor 40a, and the storage battery 3 are arranged on a straight line in the longitudinal direction (front-back direction) of the cleaner body 1. Particularly, the dust case 2 and the electric motor 40a are arranged coaxially in the longitudinal direction (front-back direction) of the electric vacuum cleaner 100. The electric motor 40a and the storage battery 3 require a large space for installation. However, since the electric motor 40a and the storage battery 3 are arranged in line with the dust case 2, the vertical width of the cleaner 100 can be narrowed and the cleaner 100 can be made compact.

In FIG. 6, an arrow F indicates the flow of air sucked into the electric vacuum cleaner 100. The air sucked into the dust case 2 enters the electric blower 40. The air passes around the electric motor 40a to cool the electric motor 40a. Further, a part of the air that has passed through the electric motor 40 a flows in the storage battery 3 and cools the storage battery 3. The remaining part of the air that has passed around the electric motor 40a and the air that has passed through the storage battery 3 merge at the circuit board 50 to cool the circuit board 50, and then discharged to the outside of the system of the vacuum cleaner 100. ..

In this case, since the storage battery 3 is arranged directly behind the electric motor 40a, cooling air can easily flow in the storage battery 3. Thereby, the storage battery 3 can be easily cooled efficiently.

A circuit board accommodating space 50a for accommodating the circuit board 50 is provided in the housing behind the introduction pipe 14 and above the electric motor 40a. Since the introduction pipe 14 has to be formed in the front portion of the cleaner 100 to generate a swirling flow inside the dust case 2, there is a certain amount of vertical thickness. Therefore, even if the circuit board housing space 50a is formed in the casing of the cleaner 100 with a certain amount of vertical thickness behind it, the overall thickness of the vacuum cleaner 100 in the vertical direction does not increase. Therefore, if the circuit board 50 is housed in the circuit board housing space 50a, it is not necessary to separately provide another space for housing the circuit board 50, so that it is possible to suppress an increase in the vertical thickness of the cleaner 100.

Further, in this case, since the arrangement position of the circuit board 50 becomes high, the connection between the circuit board 50 and the connection port 10a provided with the connection terminal for the accessory and the operation button 12b can be shortened. Therefore, the manufacturing cost of the cleaner 100 can be reduced by shortening the wiring and improving the workability during manufacturing.

7 and 8 are enlarged cross-sectional views around the release buttons 18a and 18b. By pressing any of the release buttons 18a and 18b, the connection of the accessories such as the extension pipe 300 and the standard suction port 400 to the cleaner body 1 can be released. FIG. 7 shows a state in which neither the release button 18a nor the release button 18b is pressed. In this state, first, when the release button 18a is pressed, the release button 18a and its base end portion 18a1 tilt forward and downward. As a result, the predetermined lock mechanism is released, and the accessory can be removed from the cleaner body 1.

On the other hand, as shown in FIG. 8, when the release button 18b is pressed, the release button 18b and its base end portion 18b1 tilt forward and downward. A long shaft-shaped member 18c is arranged between the base end 18a1 of the release button 18a and the base end 18b1 of the release button 18b. When the base end 18b1 of the release button 18b is tilted to the front lower side, the base end 18b1 pushes one end of the shaft-shaped member 18c forward. Then, the shaft-shaped member 18c moves in the forward direction, the other end presses the base end portion 18a1 of the release button 18a, and the release button 18a and the base end portion 18a1 tilt forward and downward. As a result, as shown in FIG. 8, the predetermined lock mechanism is released, and the airtight holding member 90 can be removed from the cleaner body 1.

By providing the release button 18b in addition to the release button 18a, the user of the electric vacuum cleaner 100 operates the release button 18b while holding the first grip portion 12a1 to remove the accessory from the cleaner body 1. You can

FIG. 9 is a side view of the vacuum cleaner as viewed from the right side.

Attachment/detachment mechanisms 2g and 19 for attaching/detaching the dust case 2 to/from the cleaner body 1 are provided at the lower rear end of the dust case 2 and the lower front end of the cleaner body 1. That is, when the dust case 2 is attached to the cleaner body 1, the attachment/detachment mechanism 2g and the attachment/detachment mechanism 19 are connected by a predetermined mechanism. The attaching/detaching mechanisms 2g and 19 extend to the lowermost part of the electric vacuum cleaner 100, and in particular, the lower end of the attaching/detaching mechanism 19 is the lowermost part of the electric vacuum cleaner 100, and the leg portion 19a is provided below the attaching/detaching mechanism 19. Has been. Further, a leg portion 3n is also provided at the lower end of the rear end of the storage battery 3.

When the electric vacuum cleaner 100 is placed on a horizontal plane F with the lower side facing downward, heavy parts such as the electric motor 40a and the storage battery 3 may be present in the lower rear part of the electric vacuum cleaner 100. The cleaner 100 is supported on the horizontal plane F by the legs 19a and 3h. At this time, since the leg portion 19a is located at the lowermost end of the electric vacuum cleaner 100, and the leg portion 19a is present at an intermediate position in the longitudinal direction of the electric vacuum cleaner 100, the electric load placed on the horizontal plane F is set. As shown in FIG. 9, the front surface of the cleaner 100 faces diagonally upward. Therefore, the tip of the connection port 10a, which serves as a suction port, also faces obliquely upward. Therefore, the tip 90s of the airtight holding member 90 also faces diagonally upward. Therefore, when the electric vacuum cleaner 100 is supported on the horizontal plane F, the dust remaining inside the connection port 10a and the airtight holding member 90 is unlikely to spill outside.

As shown in FIG. 9, the storage battery 3 can be charged by connecting an AC adapter (not shown) to the terminal t provided on the right side of the cleaner body 1.

FIG. 10 is a side view of the electric vacuum cleaner of the present embodiment viewed from the left side.

11 is a sectional view taken along line XI-XI of FIG.

In the casing structure of the electric vacuum cleaner 100, the casing 20 that covers the electric motor 40a and the circuit board 50 is a single flame-retardant case. Since the electric motor 40a and the circuit board 50 are not covered with the double or triple case structure, the electric vacuum cleaner 100 can be reduced in weight.

12 is a sectional view taken along line XII-XII of FIG.

As shown in FIG. 12, the storage battery 3 is an assembled battery, and five unit cells 3h (battery cells) are arranged side by side in the case 3a, two on the top and two on the bottom, and one in the center. It is arranged. In this way, by directing the axial direction of the unit cell 3h in the front-back direction, the width of the storage battery 3 can be made narrower than in the case where the axial direction of the unit cell 3h is directed in the left-right direction.

Further, the unit cell 3h is accommodated in the case 3a while being held by a holding member 3j made of synthetic resin. The holding member 3j is configured such that a gap 3k is formed between the upper unit cell 3h and the lower unit cell 3h.

By forming such a gap 3k, air can be caused to flow around each unit cell 3h, and each unit cell 3h can be effectively cooled.

FIG. 13 is a plan view showing a state in which accessories are connected to the vacuum cleaner.

As shown in FIG. 13, the electric vacuum cleaner 100 is configured so that the extension tube 300 can be connected in a state where the airtight holding member 90 is connected to the cleaner main body 1. Thus, the position of the connection port 10a for connecting the extension pipe 300 does not change even when the airtight holding member 90 is still connected to the cleaner body 1. Therefore, the total length L connecting the cleaner body 1, the extension pipe 300, and the standard suction port 400 can be kept short. As a result, the position of the standard suction port 400 becomes closer to the user's hand, so that the handling is improved and usability can be improved.

In the electric vacuum cleaner 100 shown in FIG. 13, even if the extension tube 300 to which the standard suction port 400 is connected is removed from the stick state to be in a handy state, the airtight holding member 90 is still attached to the cleaner body 1. .. Therefore, cleaning can be performed in a state where the suction force is increased.

In the embodiment of FIG. 13, the case where the extension tube 300 and the standard suction port 400 are connected to the vacuum cleaner 100 has been described as an example, but the present invention is not limited to this embodiment. For example, the standard suction port 400 can be directly connected to the connection port 10a and used as the electric vacuum cleaner 100 in the handy state. As a result, the airtight holding member 90 enhances the airtightness with the floor surface, so that the suction force can be increased.

As described above, in the electric vacuum cleaner 100, various accessories (attachments) can be attached and detached while the airtight holding member 90 is attached to the main body 1 of the vacuum cleaner, and the usage pattern of cleaning can be quickly switched to perform cleaning. be able to. Further, since the airtight holding member 90 can be left attached to the cleaner body 1, the handheld vacuum cleaner 100 having the airtight holding member 90 attached thereto can perform cleaning while ensuring a high suction force.

FIG. 14: is a perspective view which shows the support stand of an electric vacuum cleaner. The support base 70 shown in FIG. 14 is in a state in which the electric vacuum cleaner 100 and all accessories (attachments) are removed. As shown in FIG. 14, the support base 70 includes a base portion 71 and a stand portion 72.

The base portion 71 has a substantially rectangular mounting surface 71a on which the standard suction port 400 (see FIG. 1) is mounted. The mounting surface 71a is provided with a locking portion 71a1 that locks the standard suction port 400 from sliding down to the front side.

The stand portion 72 extends vertically upward from a stand portion support portion 71b provided behind the placement surface 71a. An engagement portion 72a is provided on the upper front portion of the stand portion support portion 71b.

FIG. 15 is a side view showing the vacuum cleaner and the support base.

As shown in FIG. 15, the electric vacuum cleaner 100 is supported by the support base 70 while the extension tube 300 and the standard suction port 400 are still connected to the vacuum cleaner body 1. Specifically, a substantially L-shaped hook 301 having a tip end on the lower side is provided at the tip end of the extension tube 300. Then, the hook 301 is engaged with the engaging portion 72a (FIG. 14) provided on the stand portion 72 of the support base 70. Further, the standard suction port 400 is locked to the locking portion 71a1 on the mounting surface 71a. Accordingly, the entire vacuum cleaner 100 can be supported by the support base 70 with the cleaner body 1 side being the upper side and the standard suction port 400 side being the lower side.

As described above, since the electric vacuum cleaner 100 can be installed on the support base 70 in the stick state, the electric vacuum cleaner 100 can be immediately used in the stick state when cleaning next time.

The mounting surface 71 a of the base portion 71 is formed so as to extend forward of the extension pipe 300.

The vacuum cleaner 100 can be moved back and forth. Thus, when the user cleans the floor surface, the position of the handle portion 12 can be changed to carry out the cleaning.

FIG. 17 is a usage pattern diagram when cleaning a high place with an electric vacuum cleaner in a stick state.

By the way, in an electric vacuum cleaner (see Japanese Unexamined Patent Application Publication No. 2016-137165) in which the center of gravity is on the tip side when in the stick state, when the electric vacuum cleaner is cleaned at a place higher than the floor surface, the user of the electric vacuum cleaner Since it is necessary to lift the tip upward, it is easy to put a strain on the wrist.

Therefore, in the present embodiment, as shown in FIG. 17, the electric blower 40 (see FIG. 6) and the storage battery 3, which are heavy items of the electric vacuum cleaner 100, are located near the handle portion 12 (position near hand). The center of gravity G of the electric vacuum cleaner 100 comes close to the user's hand. Accordingly, even when the electric vacuum cleaner 100 is in a stick state and the electric vacuum cleaner 100 is cleaned at a place higher than the floor surface, it is easy to clean and the usability can be improved. In FIG. 17, the case of cleaning the stairs has been described as an example, but it is also effective when lifting the electric vacuum cleaner 100 to clean the panel of the indoor unit of the air conditioner.

Further, when the electric vacuum cleaner 100 is used in a stick state, when removing dust remaining at the corners of the stairs, the extension pipe 300 and the standard suction port 400 are removed from the electric vacuum cleaner 100 to make it a handy state. To do. In this case, since the airtight holding member 90 is still attached to the electric vacuum cleaner 100, it is possible to perform cleaning with the suction force increased and prevent dust from remaining unsucked.

FIG. 18 is an exploded view of a portion of the motor case portion 11 that supports the electric blower 40. Further, FIG. 19 shows an enlarged view of a portion supporting the electric blower 40 of FIG.

The electric blower 40 includes an electric motor 40a, a rotary blade 40b, a fixed blade 40c, and a rotary blade casing 40d. The electric motor 40a is fixed to the fixed blade 40c with a screw, and the rotary blade casing 40d is fixed at three points of the claw portion 40d2. The rotary blade 40b is fixed to the shaft 40a1 of the electric motor 40a with a nut 40a2. An opening 40d1 is provided substantially in the center of the rotary vane casing 40d, and the air passing through the dust case 2 is sucked through the opening 40d1.

The electric blower 40 is supported by the elastic member A 40e and the elastic member 40f with respect to the motor case portion 11. The elastic member 40f is held so as to pierce the protrusion 40c1 provided on the fixed blade 40c, and can be attached to the groove 11b of the motor case portion 11. By holding the fixed blades 40c, the outer shell of the electric motor 40a is made of metal, and the elastic member 40f does not come into direct contact with the elastic member 40f even when it is heated to a high temperature. It can be formed of an easy resin.

In the present embodiment, the elastic member A40e is formed integrally with the rotor blade casing 40d of the electric blower 40, and the rib A11a1 inside the motor case lid portion 11a supports the surface A40e1 of the elastic member A40e to move in the vertical and horizontal directions. The vibration is suppressed and the rib B11a2 supports the surface B40e2 to suppress the vibration in the front-rear direction, and the airtightness of the rotor casing 40d and the motor case lid portion 11a is ensured, so that the suction force of the electric blower 40 is reduced. It can be transmitted to the suction port 10a of the cleaner body 1. In addition, the elastic member A40e may be integrated with at least a part of the rotary blade casing that is divided into a plurality of parts as long as the above effects can be obtained.

An elastic member B40g is provided inside the rotary vane casing 40d so as to abut the fixed vane 40c. As a result, the airtightness of the fixed blade 40c and the rotary blade casing 40d is ensured, and all the suction force generated by the rotary blade 40b and the fixed blade 40c can be transmitted to the opening 40d1 of the rotary blade casing 40d.
