Detailed Description
Hereinafter, a mode for carrying out the present invention (hereinafter, referred to as "embodiment") will be described in detail with reference to the accompanying drawings as appropriate.
Fig. 1 is a perspective view showing a state in which the electric vacuum cleaner of the present embodiment is housed in a support base.
As shown in fig. 1, the electric vacuum cleaner 100 can be changed to a hand-held state, a stick-type state, and other various usage modes to perform cleaning. The support stand 70 for housing the electric vacuum cleaner 100 is a rod-type support stand for housing the electric vacuum cleaner 100 in a state in which an extension pipe 300 (accessory) and a standard suction port body 200 (accessory) are connected, and is configured to include a base portion 71 and a holder portion 72. The electric vacuum cleaner 100 can be connected to a small suction port (accessory), a broom-type suction port (accessory), an extension hose (accessory), and the like, all of which are not shown. The standard suction port body 200 is a power brush type suction port body in which a brush is rotated by a motor.
Fig. 2 is an exploded view of the electric vacuum cleaner of the present embodiment. In the drawings shown below in fig. 2, the front, rear, left, right, and up and down directions as viewed from the cleaner body 1 are appropriately shown.
As shown in fig. 2, the electric vacuum cleaner 100 includes a cleaner body 1, a dust collecting case 2 (dust collecting device), a battery 3, and an airtight holding member 90.
The cleaner body 1 includes a body 10, a motor casing 11, and a handle 12.
The main body 10 is formed with a connection port 10a (suction port) for connecting the extension tube 300, the standard suction port body 200 (see fig. 1), and the like. The connection port 10a is molded from the same resin as the main body 10, the motor housing 11, the handle 12, and the like. The connection port 10a has a substantially circular opening and is formed to face forward. The connection port 10a is capable of connecting the extension tube 300, the standard suction body 200, a small suction port (not shown), a broom-type suction port (not shown), and the like (hereinafter, these may be collectively referred to as attachments) as accessories. The connection port 10a includes a terminal (not shown) electrically connected to the circuit board 50 (see fig. 6), and when a motor-driven accessory such as the standard suction port body 200 is connected, the brush is electrically connected to the motor to rotate the brush.
The main body 10 is detachably attached with the dust box 2, and is provided with an inlet pipe 14 (see fig. 3) for sending air containing dust sucked from the connection port 10a into the dust box 2.
The motor case 11 incorporates an electric blower 40 (see fig. 6) and a circuit board 50 (see fig. 6). A circular suction port (not shown) for sucking in clean air collected in the dust collecting case 2 is formed in the front surface of the motor housing 11.
The handle 12 is provided on the rear side of the body 10 and has a grip portion 12a formed in a substantially L shape. The grip 12a includes a first grip 12a1 extending linearly in the front-rear direction so as to become gradually higher toward the rear side, and a second grip 12a2 extending linearly in the substantially vertical direction. The second grip portion 12a2 of the grip portion 12a extends substantially downward from the rear end of the first grip portion 12a 1. The first grip portion 12a1 is located on the front side of the second grip portion 12a 2. The second gripping portion 12a2 is slightly inclined so that the upper portion thereof faces forward with respect to the vertical direction. The first grip portion 12a1 and the second grip portion 12a2 are formed substantially in the shape of a rod and continuously. In this way, since the first grip portion 12a1 and the second grip portion 12a2 are both linearly formed, the user can easily recognize the position of the handle. Further, since the first grip portion 12a1 and the second grip portion 12a2 are connected so as to be bent at an angle close to a right angle, when gripping the first grip portion 12a1, the hand is less likely to shift toward the second grip portion 12a2, and when gripping the second grip portion 12a2, the hand is less likely to shift toward the first grip portion 12a 1.
The first grip portion 12a1 extends so as to become gradually higher toward the rear side in the front-rear direction. Therefore, the hand is easily inserted into the gap 12c (see fig. 6).
Further, an operation button 12b is provided on the upper surface of the first gripping portion 12a1 of the handle portion 12. The operation button 12b is constituted by 3 buttons of "strong", "normal", and "off", for example.
Release buttons 18a and 18b that are operated when accessories such as the extension pipe 300 are removed are provided at the front upper portion and the rear upper portion of the main body 10. By pressing the release buttons 18a and 18b, the lock between the main body 10 and the accessory is released, and the accessory can be detached from the main body 10. The mechanism of the release buttons 18a and 18b will be described later.
Further, the airtight holding member 90 can be attached to the distal end of the main body 10. The airtight holding member 90 has a substantially circular cylindrical body 91. The cylindrical body 91 has an elastic portion 91a formed of soft resin in an annular shape on the distal end side. The cylindrical body 91 has a connecting portion 91b formed of a material harder than the elastic portion 91a and connectable to the main body 10 on the proximal end side. The cylindrical body 91 is formed by integrally molding 2 different kinds of members, i.e., the elastic portion 91a and the connecting portion 91 b. The elastic portion 91a is made of an elastically deformable (flexibly deformable) material such as an elastic body. By attaching the airtight holding member 90 to the connection port 10a of the cleaner body 1, the entire distal end 90s of the airtight holding member 90 can be brought into close contact with the floor surface, and the suction force can be increased as compared with the case where the member is not brought into close contact. Further, by forming the connection portion 91b of a hard material, the air-tightness holding member 90 can be attached to the main body 10 in a stable state without falling off.
In the present embodiment, the case where the elastic portion 91a is formed of an elastic material such as an elastomer has been described as an example, but the present invention is not limited to this. For example, the substantially entire cylindrical body 91 may be formed of the same material as the connecting portion 91b, and short bristles of electrostatic flocking may be provided in a ring shape at the tip end of the cylindrical body 91. Even if such electrostatic flocking is provided, the tip of the airtight holding member 90 can be brought into close contact with the ground surface in the same manner as the elastic body, and the suction force can be increased.
A fitting groove 10b elongated in the longitudinal direction is formed in the outer side surface of the connection port 10a of the body 10. The fitting groove 10b is formed with 1 piece on each of the left and right sides. A protruding portion (not shown) that is engaged and locked with the engagement groove 10b in a concave-convex manner is formed at the base end of the connection portion 91 b.
In addition, the main body 10 may be provided with a light emitting element above the connection port 10 a.
The battery 3 supplies electric power to a motor 40a (see fig. 6) of the electric blower 40 that generates suction force, and is constituted by a secondary battery of lithium ions, nickel hydrogen, or the like. The battery 3 has a substantially semi-cylindrical case 3a made of synthetic resin, and is detachable from the body 10 by sliding the case 3a in the front-rear direction.
Fig. 3 is a side view of the electric vacuum cleaner 100 in the state of fig. 2 as viewed from the left side.
As shown in fig. 3, the dust box 2 is a cyclone type dust box, and has a function of separating air containing dust sucked from the inlet pipe 14 into dust and air and collecting the dust. The dust box 2 is disposed in front of the motor case 11 with the axial direction being the front-rear direction, and has a substantially cylindrical housing portion 2 a. A substantially rectangular inlet port 2b (see fig. 2) connected to the inlet pipe 14 is formed in the upper surface (side surface) of the dust box 2. The air containing dust flowing into the inlet 2b is turned into a swirling flow, centrifugal force acts on the dust, the dust is separated into dust and air in the dust box 2, and the air from which the dust is separated is discharged from the rear (back) of the dust box 2.
A cover 2c that opens and closes when dust accumulated in the dust collection box 2 is discarded is rotatably supported via a hinge portion 2d on the front surface of the dust collection box 2. A cover locking mechanism 2e for unlocking the cover 2c is provided on the upper portion of the cover 2 c. The mechanism inside the dust box 2 can be configured based on japanese patent laid-open publication No. 2016-137165.
Fig. 4 is a perspective view of the electric vacuum cleaner of the present embodiment.
As shown in fig. 4, the dust box 2 of the electric vacuum cleaner 100 is attached to the lower side of the main body 10 and the front side of the motor case 11. In this case, when the dust box 2 is attached to the cleaner body 1, the cover lock mechanism 2e is hidden on the cleaner body 1 side. This is because, when the cover lock mechanism 2e is provided on the opposite side (outside), there is a possibility that the cover lock mechanism 2e is released during dust collection. However, by hiding the cover lock mechanism 2e on the cleaner body 1 side, malfunction can be prevented. For example, when dust is sucked from below a sofa or a bed in a pole-type state, the cleaner body 1 may be made nearly horizontal to the floor surface. At this time, when the lid lock mechanism 2e is provided on the front surface side, the lid lock mechanism 2e may come into contact with the ground and be released. The positions of the cover lock mechanism 2e and the hinge portion 2d are not limited to this, and may be provided on the left and right sides with respect to the cleaner body 1.
A maintenance brush 2s (see fig. 2 and 3) is detachably provided to the dust collection box 2. The maintenance brush 2s is disposed at a position that is difficult to see from the outside when the dust box 2 is attached to the cleaner body 1. Therefore, the brush is not easily detached during operation, and the maintenance brush 2s does not need to be stored in a place different from the electric vacuum cleaner 100.
Fig. 5 is a plan view of the electric vacuum cleaner of the present embodiment.
As shown in fig. 5, the connecting portion 91b of the airtight holding member 90 has extending portions 91b1, 91b1 formed on both left and right sides thereof and extending rearward. A concave portion 91b2 is formed between the left extending portion 91b1 and the right extending portion 91b1 in a plan view. The concave portion 91b2 is fitted into the front end portion 10d1 of the protruding portion 10d formed on the upper surface of the front end of the body 10. Thereby, the airtight holding member 90 is positioned in the front-rear direction and the left-right direction with respect to the connection port 10a (see fig. 2).
The inlet pipe 14 formed in the main body 10 extends obliquely rearward to the right and then extends downward, and is connected to the inlet 2b (see fig. 2) of the dust box 2. This can generate a swirling flow in the housing portion 2a of the dust box 2, and can effectively separate dust by centrifugal force.
Fig. 6 is a sectional view taken along line VI-VI of fig. 5.
As shown in fig. 6, the electric blower 40 is housed in the motor case 11 of the main body 10. The electric blower 40 is driven by a motor 40 a. In the motor case 11, a circuit board 50 (circuit board) for controlling the cleaner body 1 is housed above the electric blower 40.
The electric blower 40 and the circuit board 50 are disposed so as to overlap in the vertical direction. Therefore, the size of the cleaner body 1 in the front-rear direction can be reduced. In addition, the electric blower 40 can be formed by bulging the motor case 11 toward the handle 12, thereby reducing the dimension of the body 10 in the front-rear direction (overall length).
The electric blower 40 and the circuit board 50 are positioned below the first grip portion 12a1 of the handle 12. Thus, when the user grips the first grip portion 12a1 and operates it, the center of gravity of the electric vacuum cleaner 100 is located in the vicinity below the first grip portion 12a 1. Therefore, when the electric vacuum cleaner 100 is used with the front portion thereof facing upward, the electric vacuum cleaner 100 can be stably held.
Further, a gap 12c for inserting a hand is formed between the first grip portion 12a1 and the upper surface 11c of the motor case 11. Further, a gap 12d is formed between the second grip portion 12a2 and the back surface 11d of the motor case 11.
The thickness T1 of the first grip portion 12a1 is formed to be thin, and the thickness T2 of the second grip portion 12a2 is formed to be thicker than the thickness T1. That is, the first grip portion 12a1 is formed to be thin, and the second grip portion 12a2 is formed to be thick. In this way, when dust is sucked by gripping the second grip portion 12a2, the second grip portion 12a2 can be easily gripped deeply by increasing the thickness T2, and the strength of the second grip portion 12a2 can be increased.
The battery 3 can be formed of, for example, a lithium ion battery having high energy efficiency. The battery 3 is disposed below the second grip portion 12a2 of the handle 12. Since the battery 3 is provided at the rear end of the electric vacuum cleaner 100 in this manner, the center of gravity of the handle 12 approaches the second grip portion 12a2, and therefore, when the electric vacuum cleaner 100 is used with the front portion thereof facing upward, the operational feeling can be reduced.
The airtight holding member 90 is formed to be inclined so that the front end (front end surface) 90s recedes from the upper portion toward the lower portion so as to be substantially parallel to the dust suction surface when the second grip portion 12a2 is defined as an end portion. The dust box 2 is located rearward with respect to the surface R2 passing through the front end 90 s. Thus, even when the tip 90s of the air-tightness maintaining member 90 is brought into contact with the floor surface such as the floor, the dust box 2 can be prevented from hitting the floor surface.
In the dust box 2, a filter 5 is housed at the rear end in the axial direction of the housing portion 2 a. The filter 5 is formed by folding in a pleated manner, and the filter area can be increased and the pressure loss caused by the filter 5 can be reduced.
The Filter 5 is made of, for example, a High-density HEPA Filter (High Efficiency particulate Filter). The HEPA filter is an air filter having a particle trapping rate of 99.97% or more with respect to particles having a particle diameter of 0.3 μm and an initial pressure loss of 245Pa or less.
As shown in fig. 6, the dust box 2, the motor 40a, and the battery 3 are arranged on a straight line in the longitudinal direction (front-rear direction) of the cleaner body 1. In particular, the dust box 2 and the motor 40a are coaxially arranged in the longitudinal direction (front-rear direction) of the electric vacuum cleaner 100. The motor 40a and the battery 3 require a wide space for installation. However, since the motor 40a, the battery 3, and the dust box 2 are arranged on a straight line, the electric vacuum cleaner 100 can be made compact by narrowing the vertical width of the electric vacuum cleaner 100.
In fig. 6, the flow of air drawn into the electric vacuum cleaner 100 is shown with an arrow F. The air drawn into the dust box 2 enters the electric blower 40. The air passes around the motor 40a to cool the motor 40 a. Part of the air passing through the motor 40a flows through the battery 3, thereby cooling the battery 3. The remaining air passing around the motor 40a is merged with the air passing through the battery 3 on the circuit board 50, cools the circuit board 50, and is then discharged to the outside of the vacuum cleaner 100.
In this case, since the battery 3 is disposed immediately behind the motor 40a, the cooling air is easily flowed into the battery 3. This makes it possible to easily and efficiently cool the battery 3.
A circuit board housing space 50a for housing the circuit board 50 is provided in the housing behind the introduction pipe 14 and above the motor 40 a. In the front portion of the electric vacuum cleaner 100, the introduction pipe 14 must be formed to generate a swirling flow in the dust box 2, and thus has a certain thickness in the vertical direction. Therefore, even if the circuit board housing space 50a is formed at the rear so that the housing of the electric vacuum cleaner 100 has a slight thickness in the vertical direction, the thickness of the electric vacuum cleaner 100 in the vertical direction as a whole does not become thick. Therefore, if the circuit board 50 is housed in the circuit board housing space 50a, it is not necessary to provide a separate space for housing the circuit board 50, and thus an increase in the thickness of the electric vacuum cleaner 100 in the vertical direction can be suppressed.
In this case, since the circuit board 50 is disposed at a higher position, the wiring between the circuit board 50 and the connection port 10a and the operation button 12b, which are provided with connection terminals to accessories, can be shortened. Therefore, the manufacturing cost of the electric vacuum cleaner 100 can be reduced by shortening the wiring and improving the workability in manufacturing.
Fig. 7 and 8 are enlarged sectional views of the vicinity of the release buttons 18a and 18 b. Any one of the release buttons 18a and 18b is pressed to release the connection between the accessory such as the extension pipe 300 and the standard suction port body 200 and the cleaner main body 1. Fig. 7 shows a state where neither the release button 18a nor the release button 18b is pressed. In this state, when the release button 18a is first pressed, the release button 18a and the base end portion 18a1 thereof are tilted forward and downward. This releases the predetermined lock mechanism, and the accessory can be removed from the cleaner body 1.
On the other hand, as shown in fig. 8, when the release button 18b is pressed, the release button 18b and the base end portion 18b1 thereof are inclined forward and downward. An elongated shaft-like member 18c is disposed between the base end portion 18a1 of the release button 18a and the base end portion 18b1 of the release button 18 b. When the base end portion 18b1 of the release button 18b is tilted forward and downward, the base end portion 18b1 pushes out one end of the shaft-like member 18c in the forward direction. Then, the shaft-like member 18c moves in the forward direction, and the other end portion thereof presses the base end portion 18a1 of the release button 18a, so that the release button 18a and the base end portion 18a1 thereof are tilted forward and downward. As a result, as shown in fig. 8, the predetermined lock mechanism is released, and the airtight holding member 90 can be detached from the cleaner body 1.
By providing the release button 18b in addition to the release button 18a, the user of the electric vacuum cleaner 100 can operate the release button 18b while holding the first grip portion 12a1, and remove accessories from the cleaner body 1.
Fig. 9 is a side view of the electric vacuum cleaner as viewed from the right side.
The dust collecting case 2 has attaching and detaching mechanisms 2g and 19 for attaching and detaching the dust collecting case 2 to and from the cleaner body 1 at the lower rear end of the dust collecting case 2 and the lower front end of the cleaner body 1. That is, when the dust box 2 is mounted on the cleaner body 1, the attachment/detachment mechanism 2g and the attachment/detachment mechanism 19 are connected by a predetermined mechanism. The attachment/ detachment mechanisms 2g and 19 extend to the lowermost part of the electric vacuum cleaner 100, and particularly, the lower end of the attachment/detachment mechanism 19 is the lowermost part of the electric vacuum cleaner 100, and a foot part 19a is provided below the attachment/detachment mechanism 19. Further, a leg portion 3n is also provided at the rearmost lower end of the battery 3.
When the electric vacuum cleaner 100 is placed on the horizontal plane F such that the lower side thereof faces downward, heavy components such as the motor 40a and the battery 3 may be present in the lower rear portion of the electric vacuum cleaner 100, and the electric vacuum cleaner 100 may be supported on the horizontal plane F by the leg portions 19a and 3 n. At this time, since the leg 19a is located at the lowermost end of the electric vacuum cleaner 100 and the leg 19a is located at the middle position in the longitudinal direction of the electric vacuum cleaner 100, the electric vacuum cleaner 100 placed on the horizontal plane F is inclined forward and upward as shown in fig. 9. Therefore, the distal end of the connection port 10a serving as a suction port is also directed obliquely upward. Therefore, the front end 90s of the airtight holding member 90 also faces obliquely upward. Therefore, in the state where the vacuum cleaner 100 is supported on the horizontal plane F, dust remaining inside the connection port 10a and the airtight holding member 90 is less likely to be scattered to the outside.
As shown in fig. 9, the battery 3 can be charged by connecting an AC adapter, not shown, to a terminal t provided on the right side portion of the cleaner body 1.
Fig. 10 is a side view of the electric vacuum cleaner of the present embodiment as viewed from the left side.
Fig. 11 is a cross-sectional view taken along line XI-XI of fig. 10.
In the housing structure of the electric vacuum cleaner 100, the housing 20 covering the motor 40a and the circuit board 50 is 1 flame-retardant case. Since the motor 40a and the circuit board 50 are not covered by a 2-weight or 3-weight frame structure, the electric vacuum cleaner 100 can be reduced in weight.
Fig. 12 is a sectional view taken along line XII-XII of fig. 10.
As shown in fig. 12, the battery 3 is a battery pack, and 5 cells 3h (unit cells) are arranged in a housing 3a in a vertical arrangement of 2 cells, respectively, and in a horizontal arrangement, and 1 cell is also arranged in the center. By orienting the axial direction of the cell 3h in the front-rear direction in this manner, the width of the battery 3 can be made narrower than in the case where the axial direction of the cell 3h is oriented in the left-right direction.
The cell 3h is housed in the case 3a in a state of being held by a holding member 3j made of synthetic resin. The holding member 3j is configured to form a gap 3k between the upper layer cell 3h and the lower layer cell 3 h.
By forming such a gap 3k, air can be made to flow around each cell 3h, and each cell 3h can be cooled efficiently.
Fig. 13 is a plan view of the electric vacuum cleaner in a state in which accessories are connected to the electric vacuum cleaner.
As shown in fig. 13, the electric vacuum cleaner 100 is configured such that the extension pipe 300 can be connected in a state where the airtight holding member 90 is connected to the cleaner body 1. Thus, even in a state where the airtight holding member 90 is connected to the cleaner body 1, the position of the connection port 10a to which the extension pipe 300 is connected is not changed. Therefore, the total length L connecting the cleaner body 1, the extension pipe 300, and the standard suction port body 200 can be kept short. This enables the standard mouthpiece 200 to be positioned close to the hand, which improves handling and usability.
In the electric vacuum cleaner 100 shown in fig. 13, even when the extension pipe 300 to which the standard suction port body 200 is connected is detached from the pole type state and is held in a hand-held state, the air-tightness holding member 90 is attached to the cleaner main body 1. Therefore, dust can be sucked with the suction force increased.
In the embodiment of fig. 13, the case where the extension pipe 300 and the standard suction port body 200 are connected to the electric vacuum cleaner 100 is described as an example, but the present invention is not limited to this embodiment. For example, the standard suction port body 200 can be directly connected to the connection port 10a and used as the vacuum cleaner 100 in a hand-held state. This improves the airtightness with the floor surface by the airtight holding member 90, thereby improving the suction force.
In this way, in the electric vacuum cleaner 100, various accessories (accessories) can be attached and detached in a state where the airtight holding member 90 is attached to the cleaner body 1, and the use mode of dust collection can be quickly switched to perform dust collection. Further, since the state in which the airtight holding member 90 is attached to the cleaner body 1 can be maintained, the vacuum cleaner 100 in the hand-held state in which the airtight holding member 90 is attached can perform dust collection while securing a high suction force.
Fig. 14 is a perspective view showing a support table of the electric vacuum cleaner. The support stand 70 shown in fig. 14 is a state in which the electric vacuum cleaner 100 and all accessories (accessories) are removed. As shown in fig. 14, the support table 70 is composed of a base portion 71 and a bracket portion 72.
The base portion 71 has a substantially rectangular placement surface 71a on which the standard suction port body 200 (see fig. 1) is placed. The mounting surface 71a is provided with an engaging portion 71a1 for engaging the standard suction port body 200 to slide forward.
The holder portion 72 extends vertically upward from a holder portion support portion 71b provided behind the mounting surface 71 a. An engaging portion 72a is provided at an upper front portion of the holder support portion 71 b.
Fig. 15 is a side view showing the electric vacuum cleaner and the support base.
As shown in fig. 15, the electric vacuum cleaner 100 is supported by the support stand 70 in a state where the extension pipe 300 and the standard suction port body 200 are connected to the cleaner main body 1. Specifically, the extension pipe 300 has a front end provided with a substantially L-shaped hook 301 having a lower front end. Then, the hook 301 is engaged with an engaging portion 72a (fig. 14) of the holder portion 72 provided on the support stand 70. The standard suction port body 200 is locked to the locking portion 71a1 on the mounting surface 71 a. Accordingly, the entire electric vacuum cleaner 100 can be supported by the support base 70 with the cleaner body 1 side being an upper side and the standard suction port body 200 side being a lower side.
Since the electric vacuum cleaner 100 can be installed on the support stand 70 in a pole-type state, the electric vacuum cleaner 100 can be used in a pole-type state as it is when cleaning next time.
The placement surface 71a of the base portion 71 is formed to extend forward of the extension pipe 300. Accordingly, the standard suction port body 200 can be supported by the mounting surface 71a in a state where the standard suction port body 200 is connected to the extension pipe 300, that is, in a state where the extension pipe 300 and the standard suction port body 200 are connected to the cleaner main body 1 (a pole-type state). Therefore, the electric vacuum cleaner 100 can be stably supported by the support base 70.
Fig. 16 is a diagram showing a mode of use when the electric vacuum cleaner in the stick-type state cleans the floor.
Fig. 16 shows a state in which the extension pipe 300 and the standard suction port body 200 are connected to the electric vacuum cleaner 100 (in a state in which the airtight maintaining member 90 is mounted) to be in a stick type state, and the electric vacuum cleaner 100 is protruded forward from the user to perform dust collection on the floor surface. In this case, the user can perform dust collection by moving the electric vacuum cleaner 100 forward and backward while gripping the second gripping portion 12a2 of the grip 12. Although not shown, when the electric vacuum cleaner 100 is caused to clean the floor surface in a state in which the electric vacuum cleaner 100 is positioned on the left and right sides of the user, the user can move the electric vacuum cleaner 100 forward and backward while gripping the first gripping portion 12a1 of the handle 12. In this way, when the user cleans the floor, the user can replace the position of the handle 12 to clean the floor.
Fig. 17 is a diagram showing a usage mode of the electric vacuum cleaner in the stick-type state when cleaning a high place.
However, in the electric vacuum cleaner having the center of gravity located on the front end side in the stick-type state (see japanese patent application laid-open No. 2016-.
Therefore, in the present embodiment, as shown in fig. 17, since the electric blower 40 (see fig. 6) and the battery 3, which are heavy objects of the electric vacuum cleaner 100, are located at positions close to the handle portion 12 (positions close to the hand), the center of gravity G of the electric vacuum cleaner 100 is close to the hand of the user. Accordingly, even when the electric vacuum cleaner 100 is brought into a pole-type state and the electric vacuum cleaner 100 performs dust collection in a place higher than the floor surface, dust collection is easy, and usability can be improved. In fig. 17, the case of cleaning a step is described as an example, but the case of cleaning a panel of an indoor unit of an air conditioner by lifting up the electric vacuum cleaner 100 is also effective.
When the electric vacuum cleaner 100 is used in a stick-type state, the extension pipe 300 and the standard suction port body 200 are detached from the electric vacuum cleaner 100 and held in a hand when dust remaining at a corner (corner) of a step is removed. In this case, since the air-tightness holding member 90 is attached to the electric vacuum cleaner 100, dust can be sucked while the suction force is increased, and the dust can be prevented from being adsorbed and remaining.
Figure 18 is a top view of a standard suction body 200. As shown in fig. 2, the standard suction body 200 includes a suction port casing 210 having a substantially T-shape in plan view, and a suction port joint 213 coupled to the suction port casing 210. The suction port housing 210 is formed of an upper case 210a and a lower case 210 b.
The suction port housing 210 includes a suction port main body 211 formed to be elongated in the left-right direction (width direction) in a plan view, and a coupling portion 212 coupled to a suction port joint 213 at a central portion in the left-right direction of the suction port main body 211. The connection portion 212 has a part of the internal flow path S (see fig. 19) that connects the suction port P and the suction port joint 213.
The suction port main body 211 is provided with dampers 211a by insert molding from the front surface to the left and right side surfaces. The damper 211a is made of an elastic material such as rubber or an elastic body, or a resin material such as polypropylene, and functions as a damper that ensures airtightness inside the mouthpiece main body 211 during use, and that prevents damage to furniture or the like and absorbs impact on the mouthpiece main body 211 when the standard mouthpiece 200 collides with the furniture or the like.
The damper 211a is not necessarily provided in the mouthpiece main body 211 by insert molding, and may be provided in the mouthpiece main body 211 so as not to be accidentally detached during use, such as by adhesion or fitting with a claw.
The suction port joint 213 includes a first coupling portion 214 rotatably coupled to the coupling portion 212 and a second coupling portion 215 rotatably coupled to the first coupling portion 214. The first coupling portion 214 has a substantially D-shape in plan view in fig. 18, and has a cylindrical shaft 214a coupled to the coupling portion 212. The axial direction of the shaft 214a is the left-right direction of the suction port main body 211, and both ends of the shaft 214a are supported by bearing portions 212g (see fig. 21) formed in the coupling portion 212. The first coupling portion 214 is configured to be rotatable from a state of being substantially parallel to the floor surface (cleaning surface) M (see fig. 20) to a state of being substantially perpendicular thereto. That is, the first coupling portion 214 is pivoted about the shaft 214a as a fulcrum with respect to the mouthpiece housing 210, whereby the extension pipe 300 can be pivoted between a state substantially parallel to the floor surface M and a state substantially perpendicular thereto.
The second coupling portion 215 is configured to be rotatable in the left-right direction (clockwise direction and counterclockwise direction on the paper surface in fig. 18) of the suction port main body 211 with respect to the first coupling portion 214. This enables the extension pipe 300 to be tilted from a state in which the extension pipe 300 is substantially perpendicular to the floor surface M to a state in which the extension pipe 300 is substantially parallel to the floor surface M, for example. The second coupling portion 215 is provided with a power supply terminal 215a for supplying power. In the present embodiment, the electric power to be supplied to the standard suction port body 200 is supplied from the cleaner main body 1 through the extension pipe 300.
Fig. 19 is a bottom view of the mouthpiece body. Figure 20 is a side view of the suction body. As shown in fig. 19 and 20, the suction body 6 includes a rotary cleaning body (rotary brush) 220. A brush chamber Q having a suction port P is formed in the suction port housing 210 (suction port main body 211) on the bottom surface (surface facing the cleaning surface).
The rotary cleaning element 220 is disposed on the front side in the front-rear direction along the left-right direction of the suction port main body 211, and is rotatably supported in the brush chamber Q. The rotary cleaning element 220 includes a plurality of brushes 220a and 220b such as brushes having different hardness and height, and a rotary core for holding the brushes in a spiral shape, and is provided continuously from one end side to the other end side in the left-right direction (axial direction of the rotary cleaning element 220) of the suction port main body 211.
In the present embodiment, the case where 2 types of brushes 220a and 220b are arranged has been described as an example, but the present invention is not limited to this, and 1 type or 3 or more types may be used, and a configuration in which a blade member made of an elastic material such as rubber is arranged in a spiral shape between brushes arranged in a spiral shape may be added, and the configuration may be changed as appropriate. Since the brush structure of the rotary cleaning element 220 can be easily changed in this way, it is also possible to easily cope with a suction element for different purposes such as wood floor and carpet.
Further, since the brushes 220a and 220b are inserted into the plurality of spiral grooves, the assembly process is easy and the manufacturing cost is reduced.
The standard suction body 200 includes a brush drive switch 216 and wheels 217 on the bottom surface of the suction housing 210. The brush drive switch 216 is a switch for detecting whether or not the bottom surface of the standard suction port body 200 is in contact with the floor surface M (cleaning surface), and is configured together with the wheel 216 a. The wheel 216a is provided so as to always protrude partially from the bottom surface of the suction port housing 210 by a biasing means such as a spring. When it is detected that the wheel 216a has escaped from the suction port housing 210 and does not contact the floor surface M, the driving of the motor 240 (see fig. 21) is stopped by the control of the circuit board 250 (control board) (see fig. 21), and the rotation of the rotary cleaning element 220 is stopped. When it is detected that the wheel 216a is pressed into contact with the floor surface M, the rotary cleaning element 220 is rotated by driving the motor 240 under the control of the circuit board 250.
Fig. 22 shows a sectional view taken along line XXI-XXI of fig. 18, and fig. 23 shows an enlarged view XXII of fig. 22. An airtight packing 264 for forming a flow path is provided on the upper surface of the internal flow path S, and an LED substrate 261 having a light emitting lamp 260 is disposed between the airtight packing 264 and the upper case 210 a.
The internal flow path S is located at a portion that communicates the suction port P with the suction port joint 213. The light emitting lamp 260 is positioned above the internal flow path S and behind the suction port P. By providing the light emitting lamp 260 above the internal flow path S, the front-rear length of the standard suction port body 200 can be shortened as compared with providing a light emitting lamp in front of the suction port P, and thus the size and weight can be reduced. Further, the suction port P can be made infinitely close to the wall surface N, and dust falling near the wall surface N can be sucked. Further, by positioning the light emitting lamp 260 above the internal flow path S and behind the suction port P, the height of the front side of the standard suction port body 200 can be set to be equal to the height of the rotary cleaning body 220. This has the effect that the front of the standard suction port body 200 is more easily seen during dust collection than when the light-emitting lamp is positioned above the internal flow path S and above the suction port P. The LED holder 262 is fitted to the upper case 210a by a claw formed on the LED holder 262. The LED substrate 261 has its upper surface and left and right surfaces held by the ribs of the upper case 210a, and has its lower surface held by the LED holding portions 262c of the LED holder 262, thereby preventing the light emitting lamp 260 from swinging up and down and left and right. The LED holder 262 is provided with lens portions 262a and 262b as light refracting means, and the light emitted from the light emitting lamp 260 can efficiently reach the ground M by forming the lens portions into different shapes. Since the upper case 210a forming the outer contour of the standard suction port body 200 and the LED holder 262 as the light refracting means have the function of holding the LED substrate 261, other members for holding are not required, and the number of members can be reduced, thereby enabling weight reduction.
Further, lead wires 263 (see fig. 22) for supplying power to the LED substrate 261 are wired to the upper case 210a and the lower case 210b through the outside of the internal flow path S, connected to the circuit board 250, and supplied with power from the cleaner body 1. This enables power to be supplied to the LED substrate 261 while ensuring airtightness of the internal flow path S.
The present invention is not limited to the above-described embodiments, and various modifications are possible. For example, the above-described embodiments are examples described in detail to explain the present invention easily and understandably, and are not limited to having all of the described configurations.
