Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a vacuum cleaner with an air purifier that is used, for example, at home or installed in a car.
Regarding the arrangement structure of an electric blower.

(Prior art) A vacuum cleaner sucks up and captures relatively large pieces of dust on the floor, etc. On the other hand, an air purifier
They purify the air by trapping fine dust in the air and deodorizing it, and both are used in homes and cars. Conventionally, a vacuum cleaner and an air cleaner have been completely separate devices, and there has been no one that integrates a vacuum cleaner and an air cleaner. However, if an air purifier and a vacuum cleaner, which have become necessities in the home, are separate, each requires separate space for installation and storage, and is inconvenient.

Therefore, as described in Japanese Unexamined Patent Publication No. 62-68432, a vacuum cleaner that can also be used as an air cleaner has been proposed. In this vacuum cleaner, a front cover and a filter case can be selectively attached to the main body case with a built-in electric blower, and a hose, a handle case, and a paper bag as a dust collection filter are attached to the front cover. The structure allows the suction port to be connected via the built-in dust collection case and extension pipe. When used as a vacuum cleaner, a front cover is attached to the main case, a dust collection case is connected to the front cover via a hose, and an electric blower is driven to suck up dust and trap it in a paper bag. . On the other hand, when used as an air purifier, a filter case is attached to the main body case instead of the front cover, and the air is purified by the filter attached to the filter case while generating airflow by driving the same electric blower.

By the way, electric blowers used in vacuum cleaners generally need to have suction power that can suck up relatively large amounts of dust, so they are required to generate a large degree of vacuum and are operated at high speeds. It is. On the other hand, electric blowers used in air purifiers do not require a strong suction force, but are required to have a large suction air volume in order to process a large amount of air. Therefore, in general, the electric motor operated at low speed is small, and the fan driven by this electric motor is large. Also, while the electric blowers used in vacuum cleaners are operated only for short periods of time, the electric blowers used in air purifiers are operated for long periods of time, so they cannot be used for long periods of time. At the same time, it is required to be quiet. in this way,
An electric blower for a vacuum cleaner and an electric blower for a purifier are originally different in performance such as required rotational speed or air volume.

However, in the conventional structure described in the above publication, the same electric blower is used both when used as a vacuum cleaner and when used as a purifier, so the performance as a vacuum cleaner and the performance as an air purifier are not the same. It is not possible to accurately satisfy both of the following.

(Problem to be solved by the invention) As mentioned above, conventional vacuum cleaners that can also be used as air purifiers have only one electric blower, so the performance as a vacuum cleaner and the performance as an air purifier are not the same. There was a problem in that it was not possible to accurately satisfy both of the following.

Therefore, it is conceivable to separately provide an electric blower for a vacuum cleaner and an electric blower for a purifier in one main body, but if the electric blower is provided separately in this way, the main body will become larger, so it is difficult to The challenge is how to make the main unit more compact by installing two electric blowers.

The present invention aims to solve such problems,
The first object of the present invention is to provide an electric vacuum cleaner with an air purifier that can accurately satisfy both the performance as a vacuum cleaner and the performance as an air purifier, and the main body can be made compact. .

Furthermore, a second purpose of this vacuum cleaner with an air purifier is to reduce noise while effectively utilizing the space within the main body, and to prevent deterioration in suction performance.

A third objective is to make the main body thinner, especially in the horizontal direction, and to increase the dust collection capacity.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the first object, a vacuum cleaner with an air purifier according to claim 1 of the present invention is provided with a dust collection chamber inside and communicated with the dust collection chamber. It consists of a vacuum cleaner body having an inlet on the outside and an intake and an exhaust port on the outside, an electric motor, and a fan rotated by the electric motor, with the suction side communicating with the dust collection chamber and the exhaust side communicating with the dust collection chamber. An electric blower for a vacuum cleaner built into the vacuum cleaner main body so as to communicate with the exhaust port, an electric motor, and a fan rotationally driven by the electric motor and having a diameter larger than that of the motor, the intake side of which is communicated with the intake port. an electric blower for a cleaner built in the vacuum cleaner body with its exhaust side communicating with the exhaust port; a dust collection filter for the vacuum cleaner such as a dust collection bag provided in the dust collection chamber; and the vacuum cleaner body. a dust collection filter for a purifier provided in an air passageway from the intake port to the exhaust port via the electric blower for the purifier;
The electric blower for a vacuum cleaner and the electric blower for a cleaner have their fans oriented in opposite directions and the electric motors arranged side by side in the radial direction of each other. A part of the image is wrapped.

In addition, the vacuum cleaner with an air purifier according to claim 2,
In order to achieve the second objective, the exhaust port of the vacuum cleaner main body, which communicates with the exhaust side on the circumferential side of the electric blower for a vacuum cleaner, is connected to the exhaust side of the electric blower for a vacuum cleaner. The electric blower is arranged in a position sandwiching the electric blower, so that the electric motor chamber in which the electric blower for the purifier is installed is also used as a noise-muffling exhaust chamber of the electric blower for the vacuum cleaner. be.

Further, the vacuum cleaner with an air purifier according to claim 3 is provided with the third
In order to achieve the objective, the electric motor of the electric blower for a vacuum cleaner is located below the electric motor of the electric blower for the purifier,
Further, a suction port is provided on the upper surface of the vacuum cleaner body, and the dust collection chamber is provided below the suction port, and a fan of the electric blower for the vacuum cleaner is placed opposite to the bottom of the dust collection chamber. This is what I did.

(Function) When the vacuum cleaner with an air purifier according to claim 1 of the present invention is used as a vacuum cleaner, dust is sucked in from outside the vacuum cleaner body together with the air by driving the electric blower for the vacuum cleaner inside the vacuum cleaner body. It is sucked into the dust collection chamber through the mouth, where it is captured by the dust collection filter. The air that has been filtered by the vacuum cleaner dust filter and passed through the vacuum cleaner electric blower,
It is discharged from the vacuum cleaner body through the exhaust port. In addition, when used as an air purifier, air containing dust is sucked into the vacuum cleaner body through the intake port by driving the electric blower for the purifier inside the same vacuum cleaner body, and then passes through the electric blower for the purifier. The air is then discharged from the exhaust port, but at this time, the fine dust in the air is captured by the purifier's dust collection filter, thereby purifying the air. Of course, it can be used as a vacuum cleaner and an air purifier at the same time, but it can also be used as an air purifier alone. By the way, in order to shorten the vacuum cleaner body in which both electric blowers are disposed inside, it is best to arrange both electric blowers side by side in the radial direction. In this case, the fans of both electric blowers can be turned in opposite directions. In other words, this makes it possible to wrap the fan of an electric blower for a vacuum cleaner in the axial direction, which has a fan diameter larger than that of the electric motor, thereby reducing the distance between the two types of motors. Can be made narrower.

Furthermore, in the vacuum cleaner with an air purifier according to claim 2, during cleaning, the exhaust air discharged from the peripheral surface side of the electric blower for the vacuum cleaner is disposed within the vacuum cleaner body. The air is discharged from the exhaust port to the outside of the cleaner body through a muffling exhaust chamber that also serves as a motor chamber. At this time, the noise is muffled in the muffling exhaust chamber to reduce the noise. Also, at this time, the exhaust port of the vacuum cleaner body and the exhaust side of the electric blower for the vacuum cleaner are located across the electric motor of the electric blower for the cleaner, so that the exhaust air from the electric blower for the vacuum cleaner does not bend too much. Due to the low flow and air path resistance, electric blowers for vacuum cleaners maintain high suction performance.

In addition, in the vacuum cleaner with an air purifier according to claim 3, when cleaning, there is a suction port on the top surface of the vacuum cleaner body, and the electric blower for the purifier is placed in the lower part of the dust collection chamber below the suction port. Because the fans of the electric blower for vacuum cleaners are facing each other, air flows smoothly throughout the dust collection chamber from the suction port toward the fans.

By the way, when storing or purifying the air, the vacuum cleaner itself is placed in a corner of the room, but in order to keep the vacuum cleaner body out of the way as much as possible, the motors of both electric blowers should be lined up almost vertically. The vacuum cleaner body can be made thinner in the horizontal direction.

8 and communicated with each other.

Further, as shown in FIG. 3, on both left and right sides of the upper surface of the upper main body case 13, there are provided a vacuum cleaner switch 91 for turning on and off the electric blower 41 for the cleaner, and the electric blower 61 for the cleaner. A purifier switch 92 for turning on and off is provided, respectively.

Next, the operation of the above embodiment will be explained.

When used as a vacuum cleaner, the finger hook of the suction opening cover 33 is placed on the recess 35, and the suction opening cover 33 is rotated upward about the fulcrum part 34 to open it, and in this state, it is opened upwardly and outwardly. A connecting pipe at one end of a hose (not shown) is inserted into the suction port 31 from the outside for connection. Further, although not shown, a suction port body is connected to the grip tube at the other end of the hose via, for example, an extension tube.

Then, when the vacuum cleaner switch 91 is turned on and the vacuum cleaner electric blower 41 is operated, the fan 43 is rotationally driven by the electric motor 42, and this fan 43 generates negative pressure. Due to this negative pressure, dust is sucked into the suction port body together with air from the outside, and is guided to the dust collection chamber 16 in the vacuum cleaner main body 11 through the extension pipe and hose. Here, the dust in the air is captured in the vacuum cleaner dust collection filter 36.

On the other hand, the air from which dust has been removed by being filtered by the dust collection filter 36 is sucked into the fan cover 44 of the electric blower 41 from the intake port 47 through the grid port 20 and the circular port 21, and is drawn into the fan cover 44 of the electric blower 41. The vacuum cleaner passes through the fan 43 and the electric motor 42 and is discharged from the exhaust port 48, and then passes through the sound deadening material 49, the electric blower chamber 17 for the vacuum cleaner or the electric motor chamber 18 for the cleaner, and the exhaust filter 521, 52b. It is discharged to the outside of the vacuum cleaner main body 11 from the exhaust ports 51> and 51b.

At this time, the exhaust air from the electric blower 41 is
．． The noise generated by the flow of exhaust air is reduced by passing through the purifier motor chamber 18 in which 54 is installed. That is, the exhaust air from the electric blower 4I is routed to the cleaner motor chamber 18 side, and the exhaust air path from the electric blower 41 becomes longer within the cleaner body II.
Back pressure is reduced and a sound deadening effect is achieved. In addition, the sound deadening material 53 in the purifier motor room 18
．． 54 also provides a silencing effect. Further, noise is also muted by the sound deadening material 49 surrounding the electric motor 42. Therefore, even when used as a vacuum cleaner, the operating noise is quiet.

Incidentally, the electric motor 42 of the electric blower 41 for a vacuum cleaner is operated at high speed in order to generate a large negative pressure, but therefore the carbon inside the electric motor 42 is likely to wear out. At the same time, since air is passed through the electric motor 42 for cooling, carbon powder is included in the exhaust air.
Exhaust filter 52g covering 51b, S2b
It is captured by the cleaner and does not go out of the vacuum cleaner main body li.

Furthermore, since the exhaust ports 51g and 51b on both left and right side surfaces of the vacuum cleaner body 11 are located opposite to the exhaust port 48 on the peripheral surface of the electric motor 42 of the electric blower 41 for a vacuum cleaner, the airflow from the electric blower 41 is The exhaust air is from the exhaust port 51*,
It flows almost straight toward Slb without much bending. Therefore, since the air path resistance on the exhaust side is reduced, it is possible to prevent the suction performance of the electric blower 41 from deteriorating.

After cleaning, the hose connection pipe is pulled out from the suction port 61 and the suction port cover 33 is rotated downward to close the suction port 31.

In addition, when carrying the vacuum cleaner main body 11, the handle 39 is rotated around the fulcrum 40 as shown by the chain line in FIG.
Rotate the handle upward to stand it upright, and grasp the handle 39. At this time, since the handle 39 is located above the intermediate position of the heavy movable type movable parts 42 and 62 and above the center of gravity of the entire vacuum cleaner body 11, the vacuum cleaner body 11 can be held in a well-balanced manner.

In this way, the vacuum cleaner main body 11 is carried around, but when not cleaning,
If the vacuum cleaner main body 11 is placed and stored, for example, in a corner of a room, the vacuum cleaner main body 11 will not get in the way.

In addition, when the inside of the vacuum cleaner dust collection filter 36 is full of dust, the finger hook of the dust collection chamber lid 25 is placed in the recess 27, and the clamp part 28 is removed from the locking protrusion 30. The dust collection chamber lid 25 is rotated upward around the part 26 to open it, and the dust collection filter 36 is removed from the dust collection chamber 16 by lifting the filter backing 37 provided integrally with the dust collection filter 36. , throw away the dust in the dust collection filter 36. Thereafter, this dust collection filter 36 is reinstalled into the dust collection chamber 16, and the dust collection chamber lid 25 is closed.

On the other hand, when used as an air purifier, the vacuum cleaner body 11 is placed along the corner of the room as described above.
Turn on the purifier switch 92 and operate the purifier electric blower 61. Then, the electric motor 62 rotates the fan 63, and the fan 63 generates negative pressure. This negative pressure causes the vacuum cleaner body to
Air containing dust, particularly fine dust, is drawn from the outside into the space 60 on the rear side of the cleaner body 11 via the intake lower 7 of the intake filter cover 72 and the intake filter 76.

When the air thus sucked passes through the intake filter 76, fine dust in the air is captured by the intake filter 76. Further, the air from which fine dust has been filtered in this way flows into the fan cover 65 from the intake port 67 of the fan cover 65, passes through the fan 63 in the fan chamber 66, and then enters the exhaust port 68 of the fan cover 65. The air flows out from the cleaner body 11 through the exhaust filter 88 and is discharged from the cleaner exhaust port 89 of the exhaust filter cover 81 to the outside of the cleaner body 11. Further, the filters 76 and 88 also perform deodorization. In this way, the purified air is returned to the outside of the cleaner body 11.

The exhaust filter 88 also prevents falling dust from entering the cleaner body 11.

Of course, such use as an air purifier can be performed alone, but it can also be used simultaneously with use as a vacuum cleaner.

Note that the air flow during cleaning and air purification is indicated by arrows in FIGS. 1 and 2.

Furthermore, when replacing the intake filter 76, both claws 73 of the intake filter cover 72. ．． 74 to the main case 12. 13 from the upper and lower edges of the opening 71, and remove the intake filter cover 72 from the main body case 12°1.
3, remove the dirty intake filter 76, install a new intake filter 76, and reattach the intake filter cover 72 to the main body case 12.13. To replace the exhaust filter 88, remove the claws 82 and 83 of the exhaust filter cover 81 from the locking hole 84 and locking protrusion 85 on the main body case 12.13 side, and then replace the exhaust filter cover 81. Main body case 12.
Do this with it removed from 13.

According to the above configuration, since the vacuum cleaner and air purifier, which have become essential items in homes, are integrated, the storage of the vacuum cleaner can be used to install the air purifier, saving installation space. It's convenient.

In addition, an electric blower 41 for a vacuum cleaner and an electric blower 6 for a purifier
1 are provided separately, it is possible to accurately satisfy both the performance as a vacuum cleaner and the performance as an air purifier. That is, electric blower 4 for vacuum cleaner
1 can generate a large degree of vacuum through high-speed operation and obtain a strong suction force.On the other hand, the electric blower 61 for purifier can obtain a large air volume even when operated at low speed, and can operate quietly for a long time. What is possible and what can be done.

In addition, in both electric blowers 41.61, the fans 43.63 are oriented in opposite directions, and the electric motors 42.62 are arranged in the radial direction, so even though there are two electric blowers 41.61, These electric blowers 41.degree. 61 can be arranged compactly within the vacuum cleaner main body 11, and the vacuum cleaner main body 11 can be shortened in each direction and miniaturized.

That is, if both electric blowers were arranged coaxially and linearly in the longitudinal direction, the width of the vacuum cleaner body in the vertical and horizontal directions could be reduced, but the vacuum cleaner body would become extremely long in the longitudinal direction. If the main body of the vacuum cleaner is long in the front-rear direction and the main body of the vacuum cleaner is moved while cleaning, it will not be able to turn easily and the running performance will be poor. On the other hand, if both electric blowers 41, 61 are arranged in the radial direction with the front and back direction as the axial direction, as described above,
The cleaner main body 11 can be shortened in the front-rear direction.

Furthermore, even if both electric blowers are arranged in the radial direction of each other, if the fans are oriented in the same direction, the distance between the two electric blowers is determined by the distance between these fans whose diameter is larger than that of the electric motor, or the distance between the fans and the electric motor. Therefore, the width of the vacuum cleaner main body 11 becomes thick in the direction in which they are lined up.On the other hand, if the fans 43.63 are oriented in opposite directions as described above, the position of each fan 43.63 can be adjusted to match the electric motor. 42.
62 in the axial direction, the distance between these electric motors 42.62, which have smaller diameters, becomes the only condition that defines the distance between both electric blowers 41.61. For example, the width of the cleaner body 11 in the left-right direction can be reduced.

Further, an exhaust port 48 on the peripheral surface of the electric blower 41 for a vacuum cleaner
Since the vacuum cleaner exhaust port 51b of the vacuum cleaner main body 11 is arranged at a position sandwiching the electric motor 62 of the cleaner electric blower 61, the cleaner electric motor chamber 18 in which the smaller electric motor 62 is housed can be used as the vacuum cleaner electric blower. 41 noise-muffling exhaust chambers,
As mentioned above, it is possible to achieve quietness. At the same time, the space within the vacuum cleaner body 11 can be used effectively, and the vacuum cleaner body 11 can be downsized.

In addition, since the electric blower 41 for the purifier operates at a low speed, its operation is not only silent. Therefore, regarding this electric blower for a cleaner 41, the electric blower for a vacuum cleaner 6
1 No noise countermeasures are required.

FIG. 5 shows a second embodiment of the present invention. In this embodiment, a front wheel 96 is rotatably provided on the lower front part of the cleaner body 11, and a front wheel 96 is rotatably provided on the lower rear side of the cleaner body 11. A pair of left and right rear wheels 97 are pivotally connected to the rear wheels 97.

In addition, in the dust collection filter for a purifier, the intake filter 76 has the main dust collection function, and the exhaust filter 88 is an auxiliary one that does not necessarily need to be used. filter 88
is disposed on the upper surface of the cleaner body 11, and a thick intake filter 76 is disposed on the rear surface of the cleaner body If. Further, in the previous embodiment, the handle 39 was disposed above the exhaust filter 88, whereas in this embodiment, the handle 39 is disposed in front of the exhaust filter 88 in the horizontal direction.

If both filters 76 and 1111 are arranged in this way,
The entire vacuum cleaner body 11 can be made low in height. The presence of the front wheels 96 and the rear wheels 97 together with the low height of the cleaner body 11 improves the running performance, that is, the mobility, of the cleaner body 11 during cleaning.

In the above embodiment, the vacuum cleaner main body 1 faces the vacuum cleaner electric blower chamber 17 and the cleaner electric motor chamber 18, respectively.
Vacuum cleaner exhaust ports 51g and 51b on both left and right sides of 1
However, the exhaust port 51 on the side of the vacuum cleaner electric blower chamber 17
1 may be omitted, and the vacuum cleaner exhaust port 51b may be provided only on one side of the cleaner body 11 facing the cleaner motor chamber 18.

Next, a third embodiment of the present invention will be described based on FIGS. 6 and 7. Note that the same reference numerals are given to the parts corresponding to those of the previously described embodiment, and the explanation thereof will be omitted, and the different points will be mainly explained.

The vacuum cleaner main body 11 includes a pair of left and right main body cases 12 that are connected and fixed to each other. Most of the outer surface is formed by H. An electric blower chamber 17 for a vacuum cleaner and an electric motor chamber 18 for a cleaner are vertically arranged and partitioned in the center in the front-rear direction inside the main body 11 of the vacuum cleaner. The motor room 18 located below is airtightly partitioned off by a partition wall 101. Further, the dust collection chamber 16 has a vertical dimension that is large in accordance with the cross-sectional shape of the cleaner main body It.

The handle 39 is attached to the main body case by the fulcrum part 40! 2゜13
Although supported above, the fulcrum portion 40 is located above the motor compartment 18 .

In the electric blower 41 for a vacuum cleaner, a fan 43 facing forward is opposed to the lower part of the dust collection chamber 16. Moreover, the main body case 12 faces only the electric blower chamber 17 for the vacuum cleaner. H
Vacuum cleaner exhaust ports 51 are formed at the lower portions of both left and right sides of the vacuum cleaner. An exhaust filter 52 covering these exhaust ports 51 also serves as a sound deadening material.

The electric blower 41 for a vacuum cleaner and the electric blower 61 for a purifier have fans 43 and 63 facing oppositely to each other and are located opposite to each other, and the electric motor 4
2.62 are arranged substantially vertically in the radial direction of each other.

Further, the electric motor 62 of the electric blower 61 for a cleaner is located above, and the electric motor 42 of the electric blower 41 for a vacuum cleaner, which is heavier, is located below this motor 62.

In addition, the main body case +2. A filter chamber 103 is defined by a partition wall 102 connected to the fan cover 65 in almost the entire rearmost part of the H, and the main body case 12.13 faces almost the entire filter chamber 103.
An opening 71 facing the intake port 67 of the fan cover 65 is formed on the rear surface, and an intake filter cover 72 attached to cover this opening 71 and a presser foot formed in the filter chamber 103 The intake filter 76 held between the parts 75 and 75 has approximately the same area as the opening 71, and has a larger vertical dimension in accordance with the cross-sectional shape of the cleaner body 11, and a larger vertical dimension in the front-rear direction. is taken as the thickness direction.

The exhaust filter 88 is attached to the main body case +2. The exhaust filter cover 81 is attached to the inner lower surface of the exhaust filter cover 81, which is locked when the claws 82 and 83 are engaged with the locking hole 84 and the locking protrusion 85 formed in the upper center part and the upper rear surface of H. There is.

Furthermore, a front wheel 9 is provided at the front of the lower surface of the main body case 12.13.
6, and a pair of left and right rear wheels 97 are provided at the rear of the same lower surface.

During cleaning, the exhaust air from the vacuum cleaner electric blower 41 passes through the sound deadening material 49, the vacuum cleaner electric blower chamber 17, and the exhaust filter 52, and exits the vacuum cleaner body from the vacuum cleaner exhaust port 51. At this time, the exhaust air from the electric blower 41 passes through the exhaust filter 5 which also serves as a sound deadening material.
Noise is sufficiently muffled by passing through the electric blower room 17 which has been soundproofed by No. 2.

Note that the thickness of the vacuum cleaner main body 11 in the left-right direction is determined by the outer diameter of the two fans 43.63.
Since the outer diameter of the electric motor 42.62 is smaller than the outer diameter of the electric motor 42.63, there is enough sound deadening material 4! in the exhaust air passage from the electric blower 41 for the vacuum cleaner in the vacuum cleaner main body II.
You can get space to add 1.52.

Also, during dust collection, there is a suction port 31 on the top surface of the vacuum cleaner body 11, and a fan 43 of the electric blower 41 for the vacuum cleaner is opposed to the lower part of the dust collection chamber 16 below the suction port 31. As a result, air flows smoothly throughout the dust collection chamber 16 from the suction port 31 toward the fan 43. Therefore, dust collection is performed effectively.

Further, the vacuum cleaner main body 11 is appropriately moved by the front wheels 96 and the rear wheels 97 during cleaning, and at this time, the vacuum cleaner electric blower 41, which is heavier than the cleaner electric blower 61, is positioned below the cleaner electric blower 61. Therefore, the weight stability is good, and there is little fear that the cleaner body 11 will fall over when running.

In addition, when carrying the vacuum cleaner main body 11 by the handle 39, in addition to the fact that the handle 39 is located above the heavy dual-type mower 42.62 and above the center of gravity of the entire vacuum cleaner main body 11, as described above, Electric blower for heavier vacuum cleaners 41
is located at the bottom, so the vacuum cleaner body 1 is well balanced.
You can have 1.

According to the above configuration, the two electric blowers 41.degree. 61 are arranged vertically and the vacuum cleaner main body 11 is made thinner in the horizontal direction. When used, the thin vacuum cleaner main body 11 does not get in the way, does not take up much space, and is advantageous for storage and installation.

On the other hand, if both electric blowers 41 and 61 are arranged side by side as in the first and second embodiments, the height of the vacuum cleaner main body 11 can be lowered and the running performance can be improved. It will be advantageous.

In addition, the fan 6 facing the rear of the electric blower 61 for the purifier
3, and the intake filter 76 has a thickness direction in the front-rear direction and a large dimension in the vertical direction. Therefore, the dust collection area of the intake filter 76 can be increased, and effective air purification can be achieved. I can do it. On the other hand, the fan 43 facing the front of the electric blower 41 for the vacuum cleaner is arranged to face the lower part of the dust collection chamber 16 at the frontmost part of the vacuum cleaner main body 11, and the vacuum cleaner main body 11 is placed above the dust collection chamber 16. Since the suction port 31 is provided on the top surface, the volume of the dust collection chamber 16 can be increased, and as explained earlier, air can flow smoothly and thoroughly throughout the dust collection chamber 16 from the suction port 31 to the fan 43. Combined with this, the dust collection capacity of the dust collection chamber 16 can also be increased.

In addition, in the second and third embodiments, the vacuum cleaner main body 11
The vacuum cleaner main body 11 is provided with a handle 39 for carrying and a front wheel 96 and a rear wheel 97 for movement. And the rear wheel 97 is not required.

Similarly, in a fixed-type vacuum cleaner, instead of providing a purifier exhaust port 89 on the top surface of the vacuum cleaner body 11, as shown by chain lines in FIG. A purifier exhaust port +06 may be provided in the section.

Furthermore, the partition wall 101 between the vacuum cleaner electric blower chamber 17 and the cleaner electric motor chamber 18 is removed, and a vacuum cleaner exhaust port 51 is installed at the bottom of the left and right sides of the vacuum cleaner main body 11 facing the vacuum cleaner electric blower chamber 17. Instead of providing a vacuum cleaner exhaust port 107, as shown by the chain line in FIG. The vacuum cleaner exhaust port +07 may be covered by the exhaust router 52 by extending upward.

According to this, as in the first embodiment, the exhaust air from the electric blower 41 is directed to the purifier motor chamber 18,
The exhaust air path from the electric blower 41 becomes longer in the vacuum cleaner body 11, and the back pressure is reduced, so that a noise reduction effect can be obtained, and further noise reduction can be achieved. Therefore, it is better not to have the vacuum cleaner exhaust port 51 directly facing the vacuum cleaner electric blower chamber 17. Moreover, the electric blower 41 for the cleaner is replaced by the electric blower 41 for the cleaner.
Since it also serves as a noise-muffling exhaust chamber, the space within the vacuum cleaner body 11 is effectively utilized, and the vacuum cleaner body 11 does not become larger.

In addition, it is also possible to use the exhaust port for a vacuum cleaner and the exhaust port for a purifier.

〔Effect of the invention〕

According to the present invention, the following effects can be obtained.

The vacuum cleaner with an air purifier according to claim 1 integrates a vacuum cleaner and an air purifier, so the vacuum cleaner can be stored as is, and the air purifier can be installed, saving installation space. It's convenient. In addition, the electric blower for the vacuum cleaner and the electric blower for the purifier are installed separately in the main body of the vacuum cleaner, so the electric blower for the vacuum cleaner should have a strong suction power, and the electric blower for the purifier should have a strong suction power. By using a device that is quiet, large, and capable of long-term operation, it is possible to accurately satisfy both the performance as a vacuum cleaner and the performance as an air purifier. Furthermore, at least in electric blowers for purifiers, the diameter of the fan is larger than that of the motor (7). In addition to radially arranging them, the fan of the electric blower for the cleaner is wrapped around a part of the electric blower for the vacuum cleaner in the axial direction, so both electric blowers can be arranged compactly inside the vacuum cleaner body. Therefore, the vacuum cleaner main body can be made smaller in each direction, front, back, left, right, top and bottom, and the whole vacuum cleaner main body can be made smaller.

In addition, in the vacuum cleaner with an air purifier according to claim 2, the exhaust side on the circumferential side of the electric blower for a vacuum cleaner and the exhaust port of the vacuum cleaner main body that communicates with this exhaust side are connected to the electric blower for the cleaner. The motor room in which this motor is installed is also used as a noise-muffling exhaust chamber for the electric blower for a vacuum cleaner, so when the electric blower for a vacuum cleaner is driven, the flow of exhaust air from the electric blower is controlled. By making it smooth, it is possible to prevent deterioration in suction performance, and it is also possible to achieve quietness and reduce noise while effectively utilizing the space inside the vacuum cleaner body.

In addition, in the vacuum cleaner with an air purifier according to claim 3, since both types of mowers are arranged vertically, the vacuum cleaner body can be made thin especially in the horizontal direction, and the vacuum cleaner body can be placed indoors along a wall, etc. It does not take up much space and the vacuum cleaner itself does not get in the way. Along with this, the motor of the electric blower for the vacuum cleaner is located below the motor of the electric blower for the purifier, and the suction port is placed on the top of the vacuum cleaner body, and a dust collection chamber is placed below the suction port. Since the fan of the electric blower for the vacuum cleaner is placed opposite the bottom of this dust collection chamber, the volume of the dust collection chamber itself can be increased, and the air can flow throughout the entire dust collection chamber to improve dust collection. The dust collection capacity of the chamber can be increased.
