Detailed Description
Hereinafter, an embodiment will be described with reference to the drawings.
In fig. 4 and 5, reference numeral 1 denotes an electric vacuum cleaner. The user moves the electric vacuum cleaner 1 of the present embodiment on the traveling surface S to clean dust. In the present embodiment, a horizontal type electric vacuum cleaner is shown as an example of the electric vacuum cleaner 1, but an autonomous traveling type robot cleaner or the like may be used. Hereinafter, in the present embodiment, the front-rear direction and the up-down direction of the traveling direction will be described with reference to a state in which the electric vacuum cleaner 1 is placed on the traveling surface S. In the drawings, arrow FR indicates the front side in the traveling direction of the electric vacuum cleaner 1, and arrow RR indicates the rear side in the traveling direction.
The electric vacuum cleaner 1 includes a cleaner body 2, and the electric vacuum cleaner 1 can be moved on a moving surface S by a moving mechanism 3. In addition, the cleaner body 2 contains, as stored items, for example, the following components: an electric blower 4 as a suction source; a control unit that controls the electric blower 4; and a power supply unit that supplies power to the electric blower 4 and the control unit. As the power supply unit, a cable reel device for obtaining electric power from an external power supply, a secondary battery, or the like is used. In the present embodiment, the cleaner body 2 has a cable reel device as a power supply unit, and a part of the outer shape thereof is formed into a substantially spherical shape along the shape inside the cable reel device. As shown in fig. 1, the cleaner body 2 has a bottom surface portion 6 directly opposed to the traveling surface S, and has an inclined portion 7 rising obliquely upward outward from the bottom surface portion 6 over the entire side portion from the left and right sides in front of the bottom surface portion 6 to the bottom surface portion 6. Here, the bottom surface portion 6 is not limited to a planar bottom surface portion having a curvature of 0 or a curvature of a predetermined value or less, and includes a bottom surface portion having a structure such as a concave-convex structure. The inclined portion 7 may be, for example, an inclined portion that is curved along a spherical surface, but is not limited to this, and may be an inclined portion or the like formed by connecting and bending a plurality of planes, curved surfaces, or the like.
As shown in fig. 3, the cleaner body 2 has a mounting portion 9 on the front side in the traveling direction. The mounting portion 9 is a portion to which a dust collecting device 10 for collecting dust is mounted, and the mounting portion 9 is curved along the shape of the dust collecting device 10. The mounting portion 9 is formed in a cylindrical surface shape curved toward the rear side in the traveling direction. The mounting portion 9 is provided with a communication port 11 connected to a dust collecting device 10 (fig. 4). The communication port 11 communicates with the suction side of the electric blower 4.
The electric vacuum cleaner 1 further includes a suction port 13 for dust-containing air. In the present embodiment, the suction port 13 is formed in the suction portion 14, and the suction portion 14 is located on the front side in the traveling direction, but the present invention is not limited to this, and for example, in the case where the electric vacuum cleaner 1 is a robot cleaner, the suction port 13 may be disposed on a lower portion of the cleaner main body 2 or the like. The suction unit 14 is formed in a cylindrical shape having an axial direction along the forward and backward direction of travel, and is connected to the cleaner main body 2 via a connection unit 15. The connecting portion 15 is formed in an arm shape or a belt shape, and connects both side portions of the suction portion 14 and both side portions of the cleaner body 2.
As shown in fig. 4 and 5, the air passage 17 is connected to the suction port 13. The air passage body 17 includes, for example, a suction port body, an extension pipe, a hose body, and the like. The air duct 17 includes an operation portion that is gripped by a user. The operation unit is provided with a setting mechanism for setting the start and stop of the electric vacuum cleaner 1. When the electric vacuum cleaner 1 is a robot cleaner, the air passage body 17 is not necessary.
The dust collection device 10 is attached to and detached from the cleaner body 2. The dust collection device 10 is attached to and detached from the front side of the cleaner body 2 in the traveling direction. In the present embodiment, the dust collection device 10 is attached to and detached from the attachment portion 9 and the suction portion 14 of the cleaner body 2 along the axial direction, i.e., the longitudinal direction. In the present embodiment, the dust collecting device 10 is attached from above with one end being a lower end along the vertical direction, and the dust collecting device 10 is detached by being pulled out upward, but the present invention is not limited to this, and the dust collecting device 10 may be detached according to the inclination angle of the cleaner body 2. In the present embodiment, the dust collecting device 10 is a cyclone type dust collecting device that swirls dust-containing air to centrifugally separate dust, but is not limited to this, and may be any configuration that separates and collects dust from dust-containing air and allows air to pass therethrough.
The dust collecting device 10 is formed in a cylindrical shape. The dust collecting device 10 further includes an inlet for introducing dust-containing air. The inlet is airtightly connected to the inlet 13 in a state where the dust collecting device 10 is attached to the cleaner body 2. The dust collector 10 is provided with a discharge port for discharging air separated from dust. The discharge port is airtightly connected to a communication port 11 (fig. 3) in a state where the dust collection device 10 is attached to the cleaner body 2. The dust collection device 10 can be locked to the cleaner body 2 by the locking mechanism, and the dust collection device 10 can be detached from the cleaner body 2 by releasing the locking by the locking mechanism by the detaching mechanism 19.
The dust collection device 10 is supported from below by the support member 21. The support member 21 is provided to protrude toward the front side of the cleaner body 2. The support member 21 in the present embodiment is disposed so as to be separated downward from the suction portion 14 and the connection portion 15, but is not limited thereto, and may be formed so as to be connected to the suction portion 14 and the connection portion 15. The support member 21 is located below the mounting portion 9 (fig. 3). For example, the support member 21 is formed to cover the lower portion of the mounting portion 9. That is, the support member 21 projects forward with respect to the outer shape of the cleaner body 2 as viewed from the traveling surface S. Further, the support member 21 in the present embodiment is positioned between the inclined portions 7 on both sides. The support member 21 is formed in a shape corresponding to the longitudinal direction, that is, the shape when the dust collection device 10 is viewed from the attaching/detaching direction of the cleaner body 2. That is, the support member 21 in the present embodiment is formed in a circular dish shape. The radial dimension of the support member 21 is set according to the radial dimension of the dust collection device 10, and in the present embodiment, the radial dimension of the support member 21 is slightly larger than the radial dimension of the dust collection device 10. In the present embodiment, the width of the support member 21 is set to be smaller than the width of the cleaner body 2. Therefore, the constricted portions 22 are formed between the inclined portions 7 of the cleaner main body 2 and both sides of the support member 21 in the present embodiment. As shown in fig. 1, the bottom surface portion 6 of the cleaner body 2 and the support member 21 are formed to be contracted and connected at the position of the contracted portion 22. That is, at the position of the constricted portion 22, the distance in the vertical direction of the cleaner body 2 with respect to the running surface S is greater than the distance in the vertical direction from the running surface S to the bottom surface portion 6. The connecting member may be disposed between the cleaner body 2 and the support member 21 so as to cover the respective constricted portions 22.
In addition, in the present embodiment, the traveling mechanism 3 includes: a first wheel 25 disposed on the front side in the traveling direction; and two second wheels 26 disposed on the rear side in the traveling direction. The electric vacuum cleaner 1 is supported on the traveling surface S by the first wheels 25 and the pair of second wheels 26 in a three-point support manner. That is, the running surface S is a ground surface of the first wheel 25 and the second wheel 26. Therefore, in the case where the floor surface is a hard planar surface such as a wood floor, for example, the floor surface substantially coincides with the running surface S, but in the case where the floor surface is a surface provided with a long-haired raising member such as a carpet, the floor surface does not necessarily coincide with the running surface S, and the tip end portion of the raising member constituting a part of the floor surface may extend upward with respect to the running surface S. Further, the center of gravity of the portion of the electric vacuum cleaner 1 other than the air passage body 17 is located within a range surrounded by a virtual triangle TR formed by connecting the ground contact positions of the first wheels 25 and the pair of second wheels 26, as viewed in the vertical direction. In the present embodiment, the virtual triangle TR is an isosceles triangle in which the lengths of virtual lines L connecting the first wheels 25 and the second wheels 26 are equal or substantially equal to each other.
The first wheels 25 are universal wheels disposed on the bottom surface side of the electric vacuum cleaner 1. Hereinafter, the bottom surface side of the electric vacuum cleaner 1 is a portion facing the traveling surface S when the electric vacuum cleaner 1 travels, and the shape thereof is not limited to the surface shape. In the present embodiment, the first wheels 25 are disposed below the support member 21, i.e., below the dust collecting device 10. The first wheel 25 is disposed in the center in the lateral direction. In the present embodiment, the first wheel 25 is positioned between the inclined portion 7 and the constricted portion 22 on both sides. Further, the first wheel 25 is located on the front side in the traveling direction with respect to each second wheel 26.
The first wheel 25 in the present embodiment includes: a base portion 28 provided so as to be rotatable with respect to the support member 21; and a wheel main body 29 rotatably held by the base portion 28. As shown in fig. 2, the base portion 28 is provided so as to be rotatable about a rotation axis 31 extending in the vertical direction, for example. The wheel main body 29 is provided to the base portion 28 so as to be rotatable about a rotation axis 32 extending in the left-right direction.
Note that, instead of the base portion 28 and the wheel main body 29, the first wheel 25 may be formed into a spherical shape and supported to be rotatable without an axis, or may be a fixed wheel disposed to be rotatable about the rotation axis 32.
The second wheels 26 are fixed wheels that are rotatably disposed on both side portions on the bottom surface side of the electric vacuum cleaner 1 to stabilize the travel. The second wheels 26 in the present embodiment are disposed in the cleaner body 2 so as to be bilaterally symmetrical or substantially bilaterally symmetrical. The second wheels 26 are disposed apart from each other in the left-right direction. The second wheel 26 is provided to be rotatable about a rotation shaft 34 extending in the left-right direction. Further, the second wheel 26 is provided with a radial dimension larger than that of the wheel main body 29 of the first wheel 25. Therefore, the rotation axis 34 of the second wheel 26 is disposed at a distance from the travel surface S greater than the distance of the rotation axis 32 of the first wheel 25 from the travel surface S.
As shown in fig. 1 and 2, the cleaner body 2 is provided with an auxiliary support portion 36 for preventing the cleaner body from falling over during traveling. The auxiliary support portion 36 is located on the front side in the traveling direction with respect to a virtual line L connecting the ground contact positions of the first wheel 25 and the second wheel 26. As described above, the center of gravity of the portion of the electric vacuum cleaner 1 other than the air path body 17 is located within the range surrounded by the virtual triangle TR, and therefore, the auxiliary support portion 36 is provided at a position other than the virtual triangle TR. At this time, the auxiliary support portion 36 is positioned on the front side in the traveling direction with respect to the virtual line L because the cleaner body 2 is not formed on the rear side of the virtual line connecting the ground contact positions of the second wheels 26. Preferably, the auxiliary support portion 36 is located on the front side in the traveling direction with respect to the first wheel 25. For example, in the illustrated example, the auxiliary support portion 36 is positioned further toward the front side in the traveling direction than the swivel axis 31 of the first wheel 25.
In addition, the auxiliary support portion 36 is arranged as follows: the electric vacuum cleaner 1 is normally disposed apart from the planar traveling surface S when in contact with the traveling surface S, and can support the cleaner body 2 by being in contact with the traveling surface S when the electric vacuum cleaner 1 is tilted to the front side in the traveling direction. That is, the auxiliary support portion 36 is normally disposed upward of the travel surface S by a distance H (fig. 2). Preferably, the distance H is set to a slightly small distance, for example, about 2mm to 3mm, so that the electric vacuum cleaner 1 does not largely tilt in a state where the auxiliary support portion 36 is in contact with the traveling surface S. Therefore, in the case where the floor surface is a carpet or the like including a raising member extending upward with respect to the running surface S, the auxiliary support portion 36 can be in contact with the leading end side of the raising member.
It is preferable that the auxiliary support portions 36 be disposed on both sides with respect to the second virtual line L2, when the virtual line connecting the ground contact positions of the second wheels 26 is defined as a first virtual line L1 and the virtual line connecting the midpoint of the first virtual line L1 and the ground contact position of the first wheel 25 is defined as a second virtual line L2. The auxiliary support portions 36 in the present embodiment are separated in the left-right direction and arranged in pairs, but the present invention is not limited to this, and one auxiliary support portion 36 may be arranged continuously on both sides across the center of the cleaner body 2 in the left-right direction. For example, in the illustrated example, the auxiliary support portion 36 is disposed across the first wheel 25.
In the present embodiment, the auxiliary support portion 36 is provided in the support member 21 that supports the dust collection device 10, and the auxiliary support portion 36 is disposed in the disposition portion 37 formed in a convex shape toward the travel surface S in the lower portion of the support member 21. The arrangement portion 37 is formed as: for example, a lower portion of the support member 21 facing the traveling surface S is connected to an inclined surface portion 38 inclined downward from the front side toward the rear side in the traveling direction. In the illustrated example, the auxiliary support portion 36 is located on the front side in the traveling direction with respect to the constricted portion 22, but is not limited to this, and may be disposed on a coupling member that covers the constricted portion 22 when the coupling member is provided.
The auxiliary support portion 36 may be a simple structural portion formed to be convex toward the traveling surface S, or may be a wheel. Preferably, the auxiliary support portion 36 is a wheel supported to be rotatable about a rotation axis 40 along the left-right direction. In this case, the auxiliary support portion 36 may be arranged to be inclined along the direction in which the rotation shaft 40 is inclined. In addition, the auxiliary support portion 36 may be formed to have a radial dimension smaller than that of the wheel main body 29 of the first wheel 25 and that of the second wheel 26. In the illustrated example, the distance between the center of the auxiliary support portion 36 and the travel surface S is smaller than the distance between the center of each of the wheel main body 29 of the first wheel 25 and the center of the second wheel 26 and the travel surface S. The auxiliary support portion 36 may be formed in a spherical shape, for example, and rotatably supported without a shaft.
Further, a smooth member such as a pile fabric or a nonwoven fabric having good smoothness may be preferably disposed on the surface of the auxiliary support portion 36.
Next, the operation of the embodiment will be described.
The electric vacuum cleaner 1 is normally supported on the traveling surface S by the first wheels 25 and the second wheels 26, and can travel on the traveling surface S as the first wheels 25 and the second wheels 26 rotate along the traveling surface S. At this time, the auxiliary support portion 36 is disposed apart from the traveling surface S so as not to hinder the traveling of the electric vacuum cleaner 1.
For example, when the user pulls the air path body 17 against the electric vacuum cleaner 1 in a stopped state and travels the air path body, or when the electric vacuum cleaner 1 is stopped while traveling, an inertial force may be generated on the front side in the traveling direction, and the electric vacuum cleaner 1 may tilt toward the front side in the traveling direction with the first wheel 25 or the first wheel 25 and any one of the second wheels 26 as a fulcrum. At this time, when the cleaner body 2 is made smaller in size according to the shape of the stored items, the virtual triangle TR supported by the three points of the first wheel 25 and the pair of second wheels 26 is reduced, and the area of the bottom surface portion 6 on the front side in the traveling direction of the second wheels 26 is reduced, so that the portion supporting the inclined electric cleaner 1 on the traveling surface S is reduced, and the electric cleaner 1 is easily inclined with respect to the traveling surface S. Therefore, in the present embodiment, the auxiliary support portion 36 is disposed at a position on the front side in the traveling direction with respect to the virtual line L, and when the first wheels 25 and the second wheels 26 contact the plane, the auxiliary support portion 36 is separated from the plane, so that even if the electric vacuum cleaner 1 is inclined, the auxiliary support portion 36 can support and suppress the fall-over due to the contact with the traveling surface S.
Further, since the auxiliary support portion 36 is positioned on the front side in the traveling direction with respect to the first wheel 25, the auxiliary support portion 36 can be disposed at a position where the arrangement space is larger, and the auxiliary support portion 36 can be disposed apart from the virtual line L, and therefore, the auxiliary support portion 36 can be brought into contact with the traveling surface S at a timing when the inclination of the electric vacuum cleaner 1 is relatively small, and therefore, the electric vacuum cleaner 1 is less likely to be inclined greatly, and overturning can be suppressed more reliably.
Further, since the auxiliary support portions 36 are disposed on both sides of the second virtual line L2, even when the electric vacuum cleaner 1 is inclined to either of both sides on the front side in the traveling direction, the auxiliary support portions 36 can reliably support the electric vacuum cleaner.
Further, since the auxiliary support portion 36 is formed as a wheel, for example, when a projecting step or the like is generated on the traveling surface S, the auxiliary support portion 36 is less likely to be caught by the step and easily get over the step even if the auxiliary support portion 36 comes into contact with the step, and the auxiliary support portion 36 rotates in a state where the electric vacuum cleaner 1 is supported on the traveling surface S to release the inertial force generated on the front side in the traveling direction, it is possible to suppress the electric vacuum cleaner 1 from further tilting with the auxiliary support portion 36 as a fulcrum, and to make it more difficult to tip over. In particular, since the arrangement portion 37 on which the auxiliary support portion 36 is arranged is formed to be connected to the inclined surface portion 38 and inclined, it is difficult to engage with the step or the like of the traveling surface S at a position around the auxiliary support portion 36.
Further, by making the distance of the center of the auxiliary support portion 36 from the travel surface S smaller than the distance of the center of each of the first wheel 25 and the second wheel 26 from the travel surface S, even when a small wheel is used as the auxiliary support portion 36, for example, the auxiliary support portion 36 can be disposed close to the travel surface S, and the size increase of the electric vacuum cleaner 1 around the auxiliary support portion 36 can be suppressed.
In particular, in the case where the dust collection device 10 is downsized, the support member 21 can also be downsized, but in this case, the width of the support member 21 with respect to the cleaner body 2 is reduced, and it is difficult to form a support structure of the cleaner body 2 at positions on both sides of the support member 21 protruding from the cleaner body 2 and on the front side in the traveling direction. Therefore, in the present embodiment, the first wheels 25 and the auxiliary support portions 36 are provided in the support member 21, so that the first wheels 25 and the auxiliary support portions 36 can be efficiently arranged using the arrangement space of the support member 21, and the appearance of the electric vacuum cleaner 1 is hardly impaired, and the space in which the second wheels 26 are arranged so as to be largely separated in the left-right direction can be obtained by providing the two second wheels 26 in the cleaner main body 2.
Although several embodiments of the present invention have been described, these embodiments are provided as examples, and are not intended to limit the scope of the present invention. These new embodiments may be implemented in various other forms, and various omissions, substitutions, and changes may be made without departing from the spirit of the invention.
