An exhaust port is provided above the central axis, and a structure for attaching a blower for exhausting the air in the dust collecting chamber is provided to the exhaust port.

According to this cyclone type vacuum cleaner, the dust-containing air flow sucked from the intake port forms a swirl flow along the cylindrical inner wall surface, and the upper part of the cylindrical inner wall surface is formed. To the lower part of the dust collection chamber. At this time, the dust contained in the swirl flow moves along the inner wall surface of the dust collecting chamber and is collected on the bottom surface of the dust collecting chamber.
Since the airflow is discharged leaving dust in the dust collecting chamber, it can function as an electric vacuum cleaner. Such a cyclone type vacuum cleaner is disclosed in, for example, Japanese Patent Laid-Open No. 2002-2002.
No. 17636.

[0005]

Since the cyclone type vacuum cleaner employs the cylindrical dust collecting chamber, downsizing of the main body is a big problem. For example, in the conventional example,
The dust collection chamber is placed vertically in the front of the main unit to reduce size, but the overall volume feel is still large. Further, the cyclone method has a problem that it is difficult to remove small dusts although large dusts can be removed. Therefore, a filter for collecting small dusts is provided between the dust collection chamber and the blower. Therefore, in this cyclone method, it is also necessary to remove dust adhering to this filter. Therefore, it is also important to reduce the frequency of cleaning this filter. That is, there is a problem to increase the dust collection efficiency in front of this filter. Furthermore, it is necessary to consider the maintainability of these dust collecting chambers and filters.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an electric vacuum cleaner which can be miniaturized while improving the dust collection efficiency.

Next, referring to FIGS. 3 to 5, 12 and 13, the internal structure of the cleaner body according to this embodiment will be further described. FIG. 3 is a horizontal sectional view of the cleaner body, and FIG.
Is a vertical sectional view of the cleaner body, and FIG. 5 is a lateral sectional view of the cleaner body. FIG. 12 is a comparison diagram of the diagonal arrangement and the vertical arrangement of the internal structure. FIG.
(B) is a conceptual diagram of a vertical posture (storage posture) in a vertical arrangement,
(C) is a conceptual diagram of a horizontal posture in a diagonal arrangement, and (d) is a conceptual diagram of a vertical posture (storage posture). FIG. 13 is a horizontal sectional view of a cleaner body having a battery as a power source.

First, referring to FIG. 3, in this embodiment, the auxiliary dust collecting chamber 106 and the cleaning filter chamber 107, which are arranged behind the main dust collecting chamber 105 (on the right side in the drawing), are located in the front (the hose on the left side in the drawing). When viewed from the connection part 103 side), the main dust collecting chamber 105 is arranged so as to overlap with the main dust collecting chamber 105, and the sub dust collecting chamber 106 and the clean filter chamber 107 are arranged so close to each other that a ventilation passage 110 is formed. By reducing the projected areas of the three chambers based on the cylinder, a compact cleaner body 100 with a small dead space is realized. In addition, a fan chamber 128 and a power supply chamber 12 which are divided into right and left are provided behind the sub-dust collecting chamber 106 and the cleaning filter chamber 107.
9 is arranged.

As shown in FIG. 4, in the blower chamber 128, a vertical posture with the blower unit 128a facing upward, that is, a posture in which the rotary shaft of the drive unit 128b arranged below the blower unit 128a is in the vertical position. The blower 108 is arranged in. Furthermore,
In the power supply chamber 129, a cord reel device 109, which receives power from household wiring, is arranged in a vertical posture, that is, a rotation shaft of a reel for winding a cord is horizontal.

Returning to FIG. 3, the vacuum cleaner body 100 according to this embodiment has a sub-dust collecting chamber 106 and a clean filter chamber 107, which are arranged behind the main dust collecting chamber 105.
Since the blower chamber 128 and the power supply chamber 129 are disposed substantially symmetrically on the left and right, the configuration is well balanced in terms of internal volume and weight, so that overall compactness, runnability, and conveyance are achieved. Cleaner body 1 with good design and design
00 is realized.

The main dust collecting chamber air intake 141 formed in the main dust collecting chamber 105 is
It is formed obliquely along the circumference of 5. The hose connecting portion 103 gently connects a suction hose 200 (not shown) attached toward the central axis of the main dust collecting chamber 105 and the main dust collecting chamber air intake 141 formed obliquely in the circumferential direction. A guide passage 159 that communicates is formed. Although not shown in FIG. 3, the sub-dust collecting chamber 106 is not shown.
Also, the auxiliary dust collection chamber air intake 150 is formed obliquely in the circumferential direction similar to the main dust collection chamber air intake 141.

Here, in this embodiment, the diameter E2 of the auxiliary dust collecting chamber 106 is made smaller than the diameter E1 of the main dust collecting chamber 105, so that large dust is collected in the main dust collecting chamber 105 and the auxiliary dust collecting chamber 105 The dust collecting chamber 106 collects smaller fine dust. In this embodiment, the diameter E2 of the sub-dust collection chamber 106 is set to 75 for the best dust separation efficiency.
It is set to mm. According to the experiments by the inventors, the diameter is 7
5mm has the best dust separation efficiency, but 70mm
The same effect can be obtained in the range of from 80 mm.

As described above, in the cyclone type dust collecting structure utilizing the effect of this kind of spiral flow, the separation efficiency is good when the diameter is around 75 mm, but the dust collecting capacity is small when the diameter of the dust collecting chamber is small. Very often dust has to be discarded. In addition, if the dust collection capacity is to be increased, the length of the cylindrical dust collection chamber must be increased, which leads to an increase in the size of the device.

Therefore, the inventors of the present invention collect a large amount of fine dust in the dust collection chamber having the efficient diameter and collect a large amount of dust that can be collected even if the efficiency drops. The idea was to establish a new room independently. According to this new idea, it is possible to reduce the number of times dust is discarded by first collecting a large amount of dust in a large diameter dust collection chamber where it is easy to secure a capacity. Also, by efficiently separating the air flow, which has a small dust size to a small size, in a dust collection chamber with a small diameter, it is possible to separate more efficiently the air flow that contains various dusts. it can. Moreover, even if these small dusts are accumulated without increasing the length of the dust collecting chamber, the number of times of discarding these dusts can be reduced.

In this embodiment, the main dust collecting chamber 105 has a capacity of 120 mm in diameter and a column length (height) so that a dust capacity of about 7 days in a general household can be accumulated.
Is set to 105 mm. In addition, the sub-dust collection chamber 10
6 has a length (height) of 146 mm, and the ratio of the lengths of the dust separation chamber 151 and the dust accumulation chamber 152 is set to 2: 1. Thus, in this embodiment, the main dust collection chamber 105
The dust separation chamber 151 has substantially the same length (height) and different diameters.

Further, in this embodiment, a structure is adopted in which the dust collecting chambers having different diameters are displaced in the longitudinal direction and are arranged obliquely rearward. The reason for this will be described with reference to FIG. FIG. 12A shows a conceptual view of the arrangement of the cleaner body in which the structures are vertically arranged. According to this cleaner body, since the main dust collecting chamber 105 and the sub dust collecting chamber 106 have the same length (height), the air flow discharged from the upper portion of the main dust collecting chamber 105 is directed to the side surface. In order to communicate with the arranged sub-dust collecting chamber air intake 150, the communication passage 138 communicating with the air flow is twisted while protruding upward to reach the sub-dust collecting chamber air intake 150.

In order to make the communication passage 138 have a simple structure, the upper part of the sub-dust collecting chamber 106 is arranged so as to project above the main dust collecting chamber 105, so that the main dust collecting chamber 10
The air flow discharged from the upper part of 5 is directly supplied to the sub-dust collecting chamber 10
It is possible to communicate with the sub dust collecting chamber air intake 150 provided on the side of 6. According to this structure, the lower side of the sub-dust collecting chamber 106 is left, so that the length of the sub-dust collecting chamber 106 can be increased by extending this portion, for example.

However, as described above, the sub-dust collecting chamber 10
When the 6 and the main dust collecting chamber 105 are displaced from each other, the sub dust collecting chamber 106 projects upward, which leads to an increase in the size of the cleaner main body. In view of this, in this embodiment, as shown in FIG. 7C, the sub-dust collecting chamber 106 and the main dust collecting chamber 105 are tilted rearward to achieve downsizing. According to this obliquely arranged structure, the sub-dust collection chamber 106 and the main dust collection chamber 105 can be arranged so as to be offset from each other, and thus the connection can be made with a simple structure via the communication passage 138. Further, due to this obliquely arranged structure, the length (height) of the small diameter cylinder can be made longer (higher) than the length (height) of the large diameter cylinder.

In this embodiment, a sufficient length can be secured by extending the auxiliary dust collecting chamber 106 to the height G2 of the main dust collecting chamber 105.
It becomes difficult to clean the inside of 06. Therefore, in this embodiment, the auxiliary dust collecting chamber 1 is provided with respect to the main dust collecting chamber 105.
06 is 1.5 times longer, and further, the sub-dust collecting chamber 106
By providing the dust accumulation chamber 152 at the lower part of the above, it is possible to reduce the discharge of the dust accumulated in the sub dust collection chamber 106. As a result, the height of the vacuum cleaner body 100 is kept low, and the vacuum cleaner body 100 is downsized.

Further, in this embodiment, in order to secure a sufficient cord length, a cord reel device 109 having a reel diameter of 140 mm is adopted. The front and rear lengths of the power supply chamber 129 accommodating the cord reel device 109 are longer than the front and rear lengths of the blower chamber 128 including the blower 108. Therefore, in this embodiment, the clean filter chamber 107, which has a degree of freedom in shape, is arranged in front of the power supply chamber 129, instead of the sub-dust collecting chamber 106 in which the columnar shape is essential. The clean filter chamber 107 has a semi-circular cross-section with a cylindrical rear portion cut to ensure symmetry with the sub-dust collecting chamber 106 arranged at the opposite position. This realizes the cleaner main body 100 that is symmetrical in design while absorbing the size of the power supply chamber 129.

The clean filter chamber 107 has a substantially rectangular semi-paper-like clean filter 124 (in this embodiment, a hepa filter in order to secure a wide dust collecting area in a limited space of a semi-cylindrical shape). ) Into a strip,
The folded filter is housed in a posture in which the direction of the broken line corresponds to the longitudinal direction of the clean filter chamber 107. And
Clean filter 1 housed in this clean filter chamber 107
24 is accommodated so as to bulge toward the semicircular arc.
Then, in this embodiment, an air flow containing dust is taken in from the lower side of the central axis that is housed in an arc shape, and the taken air is passed through the cleaning filter 124 and guided in the outer peripheral direction, The power is supplied to the power supply chamber 129.

In addition, in this embodiment, the blower chamber 1 is provided between the sub-dust collecting chamber 106 and the cleaning filter chamber 107.
28 for communicating between the cleaning filter chamber 107 and the cleaning filter chamber 107
By forming the, the vacuum cleaner body 100 with a small dead space is realized. In this embodiment, the handle portion 142 of the main dust collecting case 139 is housed between the sub dust collecting chamber 106 and the clean filter chamber 107 in order to further reduce the size and improve the handling. .

Further, referring to FIG. 3 and FIG. 5, in this embodiment, the blower 1 arranged in the blower chamber 128 is described.

Next, referring to FIGS. 7 and 8, the air flow path of the cleaner body 100 according to this embodiment will be described. 7A and 7B are explanatory diagrams of the air flow path. FIG. 7A is a path diagram of the entire air flow path, and FIG. 7B is an air flow path diagram in the lower case 112. FIG. 8 is a perspective view showing a state where the opening / closing lid 111 is opened.

First, in this embodiment, by operating the operation switch 301 provided on the hand handle 300 shown in FIG. 1, this operation signal is transmitted through the signal line wired in the suction hose 200 to the hose connecting portion 103. Is transmitted to the circuit board 131 via a signal line (not shown) provided in the cleaner body 100, and the circuit board 131 drives the blower 108.

When the blower 108 is driven, the dust-containing air flow taken from the suction hose 200 into the cleaner body 100 passes through the following paths to clean the cleaner body 1.
It is exhausted to the outside of 00. First, the airflow drawn into the hose connecting portion 103 is drawn into the main dust collecting chamber air intake 141 obliquely formed in the circumferential direction by the guide passage 159 without any resistance (pressed down), and Dust room 10
Taken in 5. The taken-in airflow descends along with the dust along the inner circumferential surface of the main dust collecting chamber 105, that is, descends in a vortex, rises from near the axial center of the cylinder, and is guided to the main dust collecting cover 140. . Here, the airflow is separated from the dust when the airflow changes from the descending to the ascending, and the airflow is still separated by the net filter, which is the first filter 143 provided on the main dust collecting cover 140, even if the airflow is separated. The dust contained in is removed. On the other hand, the main dust collecting chamber 105
The dust separated in (1) is accumulated at the bottom of the main dust collecting chamber 105.

The air flow that has passed through the primary filter 143 has a function of separating the main dust collecting chamber 105 and relatively large dust is removed by the primary filter 143. This air flow passes from the communication passage opening 160a provided in the ventilation passage cover 157 attached to the inner surface of the opening / closing lid 111 to the communication passage 160, and from the communication passage opening 160b to the sub dust collecting chamber air intake 150 to the sub passage. It is taken into the dust collection chamber 106.

In the auxiliary dust collecting chamber 106, the main dust collecting chamber 105
Similarly, since the sub dust collecting chamber air intake 150 is formed in the circumferential direction, the air flow taken into the sub dust collecting chamber 106 descends along the inner surface of the sub dust collecting case 145 and rises again. Then, the auxiliary dust collecting cover 146 is pulled out. The dust separated when the air flow rises is temporarily accumulated on the bottom of the dust separation chamber 151, that is, on the sub chamber partition plate 147,
It is accumulated in the dust accumulation chamber 152 through the communication port 153.

The air flow drawn from the sub-dust collecting cover 146 is taken into the blower chamber 128 from the communication passage port 160c, the communication passage 160, the communication passage port 160d, and the second filter 135. In this embodiment, a large amount of dust can be removed by the two-stage dust collection chambers 105 and 106. However, the air flow that has passed through the two-stage dust collection chambers 105 and 106 is transferred to the second filter 13
Most dust can be removed by passing through 5. The second filter 135 is a filter that can be washed and can be used repeatedly, for example, a sponge filter in this embodiment.

The air flow that has passed through the second filter 135 is taken into the blower 108a of the blower 108, cools the drive unit 108b below the blower 108a, and then is blown into the blower chamber 128. A silencer (not shown) is arranged in the blower chamber 128, and the blower chamber 128 formed of this silencer is discharged to the ventilation passage 110 from the communication port 165 in the front part of the blower chamber 128. The airflow discharged to the ventilation passage 110 is supplied to the lower side of the clean filter 124 in the clean filter chamber 107 through the communication port 166.

The airflow that has passed through the blower chamber 128 has a high degree of cleanliness so that it can be discharged to the outside of the cleaner body 100 as it is. However, in this embodiment, by passing through the cleaning filter 124, the cleanliness can be increased to the extent that a general air cleaner is used.

The air flow supplied from the lower side in the longitudinal direction of the cleaning filter chamber 107 rises, passes through the cleaning filters 124 arranged along the longitudinal direction, and is sent out from the upper portion in the longitudinal direction. This clean filter room 1
The air flow sent from 07 is sent from the communication passage port 160e to the communication passage 160, from the communication passage port 160g to the ventilation passage 110 shown in FIGS. The airflow sent to the ventilation passage 110 cools the circuit board 131 arranged in the ventilation passage 110, and is then sent to the cord reel chamber 129 to further cool the cord reel device 109, and the exhaust port 161. Is discharged to the outside of the vacuum cleaner body 100.

As described above, in this embodiment, the size of the
Two dust collection chambers (main dust collection chamber 10 equipped with the first filter 143
5 and the sub-dust collecting chamber 106) and the size of the dust through the second filter 135, the dust collecting structure adjusts the size of the dust to the main dust collecting chamber having a large capacity for a large amount of bulky dust that mainly forms the dust of a general household. Since the fine dust can be captured by the sub-dust collection chamber 106, the main dust collection chamber 105 can be mainly used for the daily dust disposal, and the sub-dust collection chamber 106 can be discarded for a number of times. Can be reduced. Moreover, in the sub-dust collection chamber 106, since the dust accumulation chamber 152 for accumulating dust and the dust separation chamber 151 are separated, it is possible to reduce the discharge of dust from the dust separation chamber 151.

Further, since the second filter 135 is provided even if it is discharged from the sub-dust collection chamber 106,
These dusts enter the blower chamber 128 and enter the blower 108.
It is possible to reduce the adverse effect on. Moreover,
