Description

  The present invention relates to a vacuum cleaner carriage and a vacuum cleaner including the same.

  As a rechargeable cordless vacuum cleaner, connected to the vacuum cleaner main body with a built-in electric blower and storage battery, a suction port body with wheels on the lower surface, an intake pipe connecting the vacuum cleaner main body and the suction port body, and the vacuum cleaner body There has been proposed a rod-like handle that is provided with an operation unit that is provided on the handle and operates an electric blower ON / OFF and a suction force (for example, see Patent Document 1).

  Since the cordless vacuum cleaner has a storage battery instead of an AC power supply, it can be cleaned using power stored in the storage battery in advance, and after cleaning is installed on the charging stand to charge the storage battery. It can be carried out.

  Cordless vacuum cleaners must be cleaned with a small amount of power stored in the storage battery, and if the intake pipe between the suction port and the main body of the vacuum cleaner is long, the pressure loss will increase and impair the suction capacity. The length is shortened.

JP 2009-50604 A

  Cleaning of the floor surface by the cordless vacuum cleaner is performed by moving the suction port body back and forth while the user tilts the handle, and sucking the dust on the floor surface together with air from the suction port of the suction port body. At this time, since the vacuum cleaner main body, which is a heavy object, is arranged below the handle, floor cleaning while supporting the handle of the cordless cleaner places a burden on the shoulder and waist of the user. Further, when the floor surface is cleaned with a cordless vacuum cleaner or a canister type vacuum cleaner, the user often takes a forward leaning posture, which places a burden on the user's waist. Therefore, cleaning with a conventional vacuum cleaner has been a heavy labor for the user. In particular, the burden increases for the elderly, and the cleaning work is affected.

Further, when the user cleans in a forward leaning posture, a force is applied to press the suction port body against the floor surface, so that the gap between the suction port body and the floor surface is reduced. For this reason, air containing dust on the floor surface is hardly sucked into the suction port, and efficient cleaning may not be performed.
In addition, when cleaning the carpet, there is almost no gap between the suction port and the carpet, and the suction port is blocked by the carpet when cleaning a carpet having a long bristle. Therefore, the air containing dust on the carpet is difficult to be sucked into the suction port, and efficient cleaning cannot be performed. In addition, there is a problem that the running resistance increases due to the suction port sticking to the carpet, which makes the handle operation heavy and difficult to handle.

  This invention is made | formed in view of such a situation, and it aims at providing the trolley | bogie for vacuum cleaners which a user can clean efficiently, and a vacuum cleaner provided with the same.

Thus, according to the present invention, it comprises a carriage part having wheels and a handle, and a suction port part attached to the front end of the carriage part so as to have a gap between the floor surface,
The suction port portion has a suction port body portion having a suction port, and a connection pipe portion connected to the suction port body portion,
A vacuum cleaner body having a pipe insertion part and an electric blower installed on the carriage part, and connecting the pipe insertion part of the vacuum cleaner body to the connection pipe part of the suction port part. A dolly for a vacuum cleaner that can be configured is provided.

  Moreover, according to another viewpoint of this invention, the vacuum cleaner provided with the said trolley | bogie for vacuum cleaners, and the cleaner main body which has an electric blower and an electrical storage part is provided.

  First, by installing the vacuum cleaner main body of the rechargeable cordless vacuum cleaner on the truck portion of the vacuum cleaner carriage of the present invention and connecting the inlet of the vacuum cleaner main body to the connection pipe portion of the suction inlet portion It becomes possible to clean the room without being restricted by the position of a commercial power source (outlet) for supplying power to the cleaner body and the movement of the electric cord having a plug connected to the commercial power source (Effect 1). .

  Secondly, since the main body of the vacuum cleaner, which is a heavy object, can be installed on the carriage unit, the user can efficiently clean with a light force and an easy posture by holding the handle of the carriage unit. Therefore, the trolley truck of the present invention is particularly suitable as a cleaning aid that can be easily cleaned without burden by an elderly person using a vacuum cleaner (Effect 2).

  Thirdly, since the vacuum cleaner main body and the suction port main body can be connected at a short distance without using a long hose, the pressure loss during cleaning can be kept small. As a result, it is possible to exert a sufficient suction force even with electric power from the storage battery in the main body of the rechargeable vacuum cleaner (Effect 3).

  Fourth, since the suction port is attached to the carriage so as to have a gap between the floor and the floor, the distance between the suction port and the floor can be set to the highest suction efficiency. Therefore, it is possible to efficiently clean even with a small amount of power (Effect 4).

  Fifth, if a wheel with a large diameter is used for the wheel of the carriage, the wheel will not sink into the carpet even when cleaning the carpet with long hairs, so the suction port will not be blocked by the carpet. Therefore, it becomes possible to perform cleaning with high suction efficiency even on carpets with long hairs (Effect 5).

In a state where the suction port main body portion 21 is lowered, the connection pipe portion 22 is in contact with the stopper rod 11a, whereby the connection pipe portion 22 is maintained in an inclined state with respect to the floor surface F at a predetermined angle. . At this time, the suction port 21a of the suction port main body 21 is arranged in parallel with a predetermined gap G between the floor surface F (see FIG. 3). The predetermined gap G is preferably set to a gap having the highest suction efficiency.

Further, by swinging the suction port body 21 and lifting it upward, the vacuum cleaner carriage C1 can be moved without causing the suction port body 21 to collide with indoor furniture or walls when the vacuum cleaner is cleared. It can be moved smoothly. In this case, it is possible to connect the pipe portion 22 is swung until it abuts against the notch 11A _1, maintains the state of being inclined connecting pipe portion 22 to the supporting section 12 side. Moreover, maintenance of the rotary brush 21b and its periphery becomes easy by opening the suction inlet 21a upward.

  The cleaner body CM1 having the pipe insertion part 51 and the electric blower 52 is installed on the carriage part 10 of the cleaner carriage C1 having the above-described configuration, and the pipe insertion part 51 of the cleaner body CM1 is connected to the suction port part 21. By connecting to the connection pipe portion 22, an upright type vacuum cleaner SC1 is configured. In order to stabilize the cleaner body CM1 without rattling, a cushion 60 may be placed between the carriage unit 10 and the cleaner body CM1. Further, although not shown, the cleaner main body CM1 may be fixed to the support portion 12 of the carriage portion 10 with a belt.

The vacuum cleaner main body CM1 includes an electric blower 52 and a power storage unit 53 provided inside the casing, and a cyclone dust collection box 55 that can be attached to and detached from the casing. The vacuum cleaner main body CM1 includes an operation unit 54 provided on the upper surface of the housing, an exhaust port 56 provided at the rear of the housing, and a male connection unit (not shown).
The operation unit 54 includes, for example, a power switch that switches ON / OFF of the cleaner main body CM1 and a power adjustment switch that switches the suction force by the electric blower 52 in a plurality of stages.

  The power storage unit 53 includes a storage battery and a charger. This charger converts an alternating current supplied from an indoor commercial power source into a direct current, reduces the direct current to a predetermined voltage, and charges the storage battery with the direct current of the predetermined voltage. When charging the cleaner main body MC1, a plug provided at one end of an electric cord (not shown) is connected to an indoor commercial power supply, and a female connection provided at the other end of the electric cord is connected to the cleaner main body CM1. Connect to male connection. Thereby, the vacuum cleaner SC1 can be charged in various rooms having a commercial power source.

  FIG. 6 is a diagram for explaining a use state of the electric vacuum cleaner shown in FIG. As shown in FIG. 6, when the room is cleaned by the electric vacuum cleaner SC1, first, the power switch of the cleaner main body CM1 is switched from OFF to ON. Thereby, the electric blower 52 and the rotating brush 21b are driven, and air containing dust is sucked into the suction port 21a of the suction port portion 21. When air containing dust is introduced into the dust collection box 55, it is separated into dust and air, and the dust accumulates in the dust collection box 55, and air that does not contain dust is discharged from the exhaust port 56 to the outside.

  At this time, since the distance from the vacuum cleaner main body CM1 to the floor surface F is short, pressure loss is suppressed, and sufficient suction port physical strength can be obtained even with the electric power charged in the power storage unit 53. Specifically, the same level of suction force can be achieved with about 30% less power than the power consumption of a canister type vacuum cleaner equipped with an extension hose.

  Thus, after the cleaner main body CM1 is set in the drive state, the user U can clean the indoor floor surface F by moving the carriage unit 10 with the handle 13. At this time, in addition to the heavy vacuum cleaner main body CM1 being installed on the carriage unit 10 having the front wheels 14a and the casters 14b, the suction port 20 is not grounded to the floor F, so that the user U The electric vacuum cleaner SC1 can be moved by pushing and pulling the handle 13 with a light force (for example, even with one finger). In addition, since the user U can clean his / her back, the user U can easily and efficiently clean his / her shoulders and hips with a leaning posture, and the caster 14b can easily change the direction.

Further, as shown in FIG. 3, the suction port body portion 21 of the suction port portion 20 is not in contact with the floor surface F, and is suspended from the floor surface F to the front end of the carriage unit 10 with a predetermined gap G. Therefore, the absence of running resistance of the suction port body 21 also contributes to easy cleaning with a light force.
Moreover, since the suction inlet main-body part 21 forms the gap | interval G from which the suction efficiency becomes the highest from the floor surface F, even if it is especially cleaning on a carpet, the suction inlet main-body part 21 closely_contact | adheres to a carpet, and the suction inlet 21a is The floor F can be efficiently cleaned with a large suction force without being blocked. In FIG. 3, a wavy line (two-dot chain line) on the floor F indicated by a straight line (solid line) represents the surface of the carpet.

  When the cleaning is completed, the vacuum cleaner SC1 is moved to a place where the commercial power supply is located, and the plug provided at one end of the electric cord as described above is connected to the indoor commercial power supply, and the other end of the electric cord is connected. Is connected to the male connection portion of the cleaner body CM1 to charge the power storage unit 53. Therefore, according to this vacuum cleaner SC1, since it is not necessary to charge in a specific place, it does not require the effort to return to a specific charge place after cleaning. During charging, the handle 13 can be folded by swinging downward so as not to get in the way.
