Description
This application claims priority based on Japanese patent application No. 2019-101210 (application date: 05/30/2019), the entire contents of which are incorporated herein by reference.
Technical Field
The utility model discloses an embodiment relates to the electric vacuum cleaner who possesses electric blower and dust collecting part.
Background
A stick-type (スティック -type) electric vacuum cleaner is used by a user gripping a grip portion provided in a cleaner body. In the cleaner body, a weight such as an electric blower, a battery, and a dust collecting unit is disposed. Conventionally, there is a structure in which a dust collection unit and an electric blower are arranged in a vertical direction, and an axial direction of the electric blower is inclined with respect to an axial direction of the dust collection unit, thereby achieving a weight balance. However, in this arrangement, the suction air passage from the dust collector to the electric blower is bent in a complicated manner, and therefore, it is not easy to improve the suction efficiency. In order to improve the suction efficiency, it is preferable that the dust collector and the electric blower are coaxially arranged so that the air passage is close to a straight line. However, in this arrangement, since the weight is arranged to extend in the longitudinal direction, the weight balance is poor and miniaturization is not easy.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an electric dust collector which can ensure the suction efficiency and simultaneously obtain the weight balance and realize the miniaturization.
The electric dust collector of the embodiment is provided with an electric blower and a dust collecting part. The dust collecting unit centrifugally separates at least a part of dust from dust-containing air sucked by the operation of the electric blower. The electric blower and the dust collecting part are arranged in parallel with each other in the axial direction and with their central axes displaced from each other. At least a part of the electric blower is located in the axial projection of the dust collecting part.
According to the electric vacuum cleaner having the above configuration, a space can be formed on the side opposite to the direction in which the electric blower is shifted from the dust collecting unit without significantly reducing the suction efficiency from the dust collecting unit to the electric blower, the arrangement efficiency can be improved, and the size can be reduced.

In the present embodiment, the dust collecting part 2 includes a cup 26 as a container for accumulating dust. The dust collecting part 2 further includes a mounting part 27 mounted to the cup part 26. The cup 26 and the mounting portion 27 are detachable from each other in the axial direction of the dust collecting part 2. The cup portion 26 constitutes one end portion of the dust collecting part 2. The mounting portion 27 constitutes the other end portion of the dust collecting section 2. An introduction port 23 is formed in a side surface of the cup 26. An exhaust port 24 is formed in an end portion of the mounting portion 27 opposite to the cup portion 26.
Further, in the present embodiment, in a state where the dust collecting unit 2 is attached to the cleaner body 1, one end portion is positioned on the grip portion 14 side with respect to the body suction port 101.
An electric blower 3 is housed in the cleaner body 1. The electric blower 3 is a heavy object. In the present embodiment, the electric blower 3 is lighter than the dust collection unit 2. The suction side of the electric blower 3 communicates with the connection port 121, and the exhaust side communicates with the main body exhaust port 123 shown in fig. 3. As shown in fig. 1, the electric blower 3 includes an electric section 31. Further, the electric blower 3 includes a fan 32 rotated by the electric unit 31. The electric blower 3 discharges the sucked air from the main body air outlet 123 shown in fig. 3 through the electric portion 31. The fan 32 shown in fig. 1 may be located upstream or downstream of the motor section 31.
The electric blower 3 is arranged with its axial direction along a first direction. The first direction is the left-right direction of fig. 1. The axial direction of the electric blower 3 is parallel to the axial direction of the dust collecting part 2. The "parallel" described below is not limited to a complete parallel, and includes a substantially parallel. The center axis 34 of the electric blower 3 is the center of the rotation axis of the electric section 31 or the fan 32. The central axis 34 of the electric blower 3 is offset from the central axis 21 of the dust collection part 2. In the present embodiment, the central axis 34 of the electric blower 3 is shifted to one side of the third direction with respect to the central axis 21 of the dust collection unit 2. The third direction is the up-down direction in fig. 1, and one direction side of the third direction is the up direction in fig. 1. In the illustrated example, the central axis 34 of the electric blower 3 is shifted toward the grip portion 14 with respect to the central axis 21 of the dust collection unit 2. The electric blower 3 is disposed so that at least a part thereof is located within a projection PR of the dust collecting part 2 in the axial direction. Preferably, the electric blower 3 is disposed so that all of it is positioned within the projection PR of the dust collection unit 2 in the axial direction. In the illustrated example, the electric blower 3 is partially disposed so as to overlap the central axis 21 of the dust collection unit 2. The projection PR in the axial direction of the dust collecting part 2 is a region extending along the axial direction of the dust collecting part 2 from the outermost range in the state where the dust collecting part 2 is viewed in the axial direction. The central axis 34 of the electric blower 3 may be shifted in the second direction shown in fig. 3 and the like with respect to the central axis 21 of the dust collection unit 2.
As shown in fig. 1, a battery 4 is housed in the cleaner body 1. At least a part of the battery 4 is disposed at a position opposite to the central axis 34 of the electric blower 3 with respect to the central axis 21 of the dust collection unit 2. That is, at least a part of the battery 4 is disposed in a space generated in a direction opposite to the direction of displacement of the electric blower 3 at a position facing the other end side of the dust collection part 2. As shown in fig. 2, in the present embodiment, since the central axis 34 of the electric blower 3 is shifted to one side in the third direction with respect to the central axis 21 of the dust collection unit 2, at least a part of the battery 4 is shifted to the other side in the third direction with respect to the central axis 21 of the dust collection unit 2.
As shown in fig. 1, the battery 4 and the electric blower 3 are disposed at positions overlapping each other in a direction intersecting the axial direction of the dust collection unit 2. That is, the battery 4 and the electric blower 3 overlap each other within a predetermined range when viewed in a direction intersecting the axial direction of the dust collection unit 2. In the present embodiment, the battery 4 and the electric blower 3 are disposed at positions overlapping each other in the third direction. Further, the battery 4 and the electric blower 3 are disposed at positions overlapping with the grip portion 14 in a direction intersecting with the axial direction of the dust collection unit 2. In the present embodiment, the grip portion 14, the electric blower 3, and the battery 4 are arranged in this order toward the other direction of the third direction.
At least a part of the battery 4 is disposed in the projection PR of the dust collecting part 2 in the axial direction. The battery 4 is disposed adjacent to the outer wall of the air passage 122 or close to the outer wall of the air passage 122. In the present embodiment, the battery 4 is located at a position away from the central axis 21 of the dust collecting part 2. In the illustrated example, the battery 4 is located at a position away from the central axis 21 of the dust collecting part 2 toward the other direction side of the third direction.
The longitudinal direction of the battery 4 is arranged along the first direction. That is, the longitudinal direction of the battery 4 is parallel to the axial direction of the dust collecting part 2.
In the present embodiment, as shown in fig. 3, the battery 4, the electric blower 3, and the dust collecting unit 2 are located at positions that are not shifted in the second direction.
In the present embodiment, the battery 4 is a heavy object having a weight larger than the dust collecting unit 2 and the electric blower 3. The battery 4 is a battery pack configured by electrically connecting a plurality of batteries in series. The battery 4 is preferably a rechargeable secondary battery.
As shown in fig. 1, a control unit 5 is housed in the cleaner body 1. The control unit 5 may be disposed at any position, but in the present embodiment, it is disposed on the opposite side of the electric blower 3 from the dust collection unit 2. That is, the control unit 5 is disposed on the other side of the first direction with respect to the electric blower 3. The control unit 5 is disposed at a position cooled by the exhaust air from the electric blower 3 toward the main body exhaust port 123 shown in fig. 3.
Next, the operation of one embodiment will be described.
When the dust collecting part 2 is attached to the cleaner body 1 as shown in fig. 1, the body suction port 101 communicates with the suction side of the dust collecting part 2, and the suction side of the electric blower 3 communicates with the exhaust side of the dust collecting part 2, thereby forming an air passage from the body suction port 101 to the dust collecting part 2, the electric blower 3, and the body exhaust port 123 shown in fig. 3.
In the present embodiment, as shown in fig. 1, if the dust collector 2 is attached to the cleaner body 1, the inlet 23 of the dust collector 2 is connected to the connection opening 103 of the cleaner body 1, the suction side of the dust collector 2 communicates with the suction air passage 102, the exhaust port 24 of the dust collector 2 is connected to the connection port 121 of the cleaner body 1, and the exhaust side of the dust collector 2 communicates with the air passage 122.
If the user operates the setting means 141 while holding the holding portion 14, the control means 5 operates the electric blower 3 in accordance with the operation of the setting means 141. The negative pressure generated by the operation of the electric blower 3 acts through the main body suction port 101, and the dust-containing air is sucked from the surface to be cleaned into the dust collecting part 2.
When cleaning the lower surface to be cleaned, one direction side in the first direction is the front side, the other direction side is the rear side, one direction side in the second direction is the left side, the other direction side is the right side, one direction side in the third direction is the upper side, and the other direction side is the lower side, as viewed by a user who grips the grip portion 14. The user sucks dust on the surface to be cleaned through the main body suction port 101 or an air passage connected to the main body suction port 101 while moving the electric vacuum cleaner VC forward and backward by the grip 14.
The air separated and captured by the dust collecting unit 2 is sucked by the electric blower 3 and discharged as exhaust air from the main body exhaust port 123 shown in fig. 3. With the exhaust of the electric blower 3, the heat of the battery 4 is drawn from the entire battery 4 and discharged to the outside of the cleaner body 1 through the body exhaust port 123 together with the exhaust air, thereby cooling the battery 4.
At this time, the electric blower 3 and the dust collecting part 2 are arranged in parallel with each other in the axial direction, and the central axes 34 and 21 are arranged in a shifted manner, and at least a part of the electric blower 3 is positioned in the projection PR in the axial direction of the dust collecting part 2, whereby a space can be formed on the side opposite to the shift direction of the electric blower 3 with respect to the dust collecting part 2 without significantly lowering the suction efficiency from the dust collecting part 2 to the electric blower 3, the arrangement efficiency is improved, and the electric vacuum cleaner VC can be downsized.
By disposing the central axis 34 of the electric blower 3 so as to be located within the projection PR of the dust collection unit 2 in the axial direction, it is possible to further suppress a decrease in suction efficiency from the dust collection unit 2 to the electric blower 3 and maintain performance.
By disposing the entire electric blower 3 so as to be positioned within the projection PR of the dust collection unit 2 in the axial direction, the electric vacuum cleaner VC can be further downsized.
By disposing at least a part of the battery 4 in the projection PR in the axial direction of the dust collection unit 2 at a position opposite to the central axis 34 of the electric blower 3 with respect to the central axis 21 of the dust collection unit 2, the electric vacuum cleaner VC can be downsized by utilizing a space opposite to the direction in which the electric blower 3 is shifted with respect to the dust collection unit 2.
In particular, when the electric blower 3 and the battery 4 are housed inside the cleaner body 1, the limited space inside the cleaner body 1 can be effectively used, and the electric cleaner VC can be downsized.
By disposing the battery 4 in parallel with the longitudinal direction of the electric blower 3, the electric blower 3 and the battery 4 can be disposed compactly, and heat generated from the battery 4 can be easily discharged from the main body air outlet 123 through the electric blower 3.
By disposing the electric blower 3 and the battery 4 at positions overlapping each other in the direction intersecting the axial direction of the dust collection unit 2, the electric blower 3 and the battery 4 can be disposed without lengthening the cleaner body 1 in the first direction, and the electric cleaner VC can be downsized.
In particular, when cleaning the lower surface to be cleaned with the grip portion 14 held, the electric blower 3 is positioned above the battery 4, and therefore, the air warmed by the heat generated by the battery 4 rises in the direction of the electric blower 3, and the electric blower 3 can discharge the heat of the battery 4 from the cleaner body 1 together with the exhaust air.
By arranging the grip portion 14 at a position straddling the electric blower 3 and the dust collection portion 2, the electric blower 3 and the dust collection portion 2 function as ballast in a state where the grip portion 14 is gripped, so that weight balance is easily obtained, and operability of the electric vacuum cleaner VC can be improved. In the present embodiment, the grip 14 is disposed at a position straddling the electric blower 3, the dust collecting unit 2, and the battery 4, so that the electric blower 3, the dust collecting unit 2, and the battery 4 function as ballast in a state where the grip 14 is gripped, thereby facilitating weight balance and improving operability of the electric vacuum cleaner VC.
By disposing the body suction port 101 on one end side of the grip 14 and disposing the center axis 105 to intersect the center axis 21 of the dust collecting part 2 at a position opposite to the grip 14, the body suction port 101 can be directed to the side to be cleaned without greatly inclining the hand gripping the grip 14 when the grip 14 is gripping the lower surface to be cleaned. Therefore, the operation of cleaning the lower surface to be cleaned can be performed while maintaining the positional relationship of the dust collection unit 2, the electric blower 3, and the battery 4, which are heavy objects, below the grip portion 14, that is, while keeping the weight balance, and the operability of the electric vacuum cleaner VC is improved.
Further, when the lower surface to be cleaned is cleaned while the grip portion 14 is gripped, the main body air outlet 123 is positioned on the upper side of the cleaner body 1 and does not directly face the surface to be cleaned, so that the exhaust air from the electric blower 3 is not discharged from below the cleaner body 1. Therefore, particularly when cleaning is performed only by the cleaner body 1 without using the air passage member, even if the cleaner body 1 is close to the surface to be cleaned, dust on the surface to be cleaned is not easily blown off by the exhaust air.
The embodiments of the present invention have been described, but these embodiments are presented as examples, and the scope of the present invention is not limited to these embodiments. These new embodiments can be implemented in other various forms, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention.
