  In conventional rechargeable vacuum cleaners, the main body of the vacuum cleaner is equipped with a battery with an appropriate capacity for use with a handheld vacuum cleaner, so a stick-type vacuum cleaner can be used to clean a wide area. In some cases, cleaning cannot be completed even if the battery is used until the battery capacity is exhausted. In some cases, a battery for outputting a stronger suction force is required. Therefore, the present invention provides a vacuum cleaner that can take a sufficient time of use and output a stronger suction force when the handheld vacuum cleaner is used as a stick-type vacuum cleaner. For the purpose.

  In order to solve the above-described problems, a vacuum cleaner according to claim 1 of the present invention is a vacuum cleaner that combines a dust-collecting unit, an electric blower, and a battery in a vacuum cleaner body, and a rechargeable stick type and a handy type. The battery is provided inside the stick, and the stick is connected to the cleaner so that the battery inside the stick is connected in parallel to the battery inside the cleaner body.

  Thus, in a vacuum cleaner that combines a rechargeable stick type and a handy type, a battery is provided inside the stick, and by connecting the stick to the vacuum cleaner, the battery inside the stick is connected in parallel to the battery inside the vacuum cleaner, That is, since the battery capacity is increased, the usage time can be extended as compared with the case of cleaning without using the stick.

  According to a second aspect of the present invention, there is provided a vacuum cleaner having a dust collecting part, an electric blower and a battery in a vacuum cleaner body, and a rechargeable stick type and a handy type vacuum cleaner. The battery inside the stick is connected in series to the battery inside the cleaner body by providing and connecting the stick to the cleaner.

  Thus, in a vacuum cleaner that combines a rechargeable stick type and a handy type, a battery is provided inside the stick, and by connecting the stick to the vacuum cleaner, the battery inside the stick is connected in series to the battery inside the vacuum cleaner, That is, since the battery voltage increases, the suction force can be increased as compared with the case of cleaning without using a stick.

  According to a third aspect of the present invention, there is provided a vacuum cleaner having a dust collecting unit, an electric blower and a battery in a vacuum cleaner body, and a rechargeable stick type and a handy type vacuum cleaner. The battery inside the stick is connected in parallel or in series with the battery inside the main body of the cleaner by switching to parallel or series connection by the changeover switch by connecting the stick to the vacuum cleaner.

  In this way, the battery inside the stick is connected in parallel or in series with the battery inside the vacuum cleaner body by switching to the parallel or series connection by the changeover switch.

Further, the suction force can be increased by increasing the battery voltage according to the connection mode between the battery inside the cleaner body and the battery inside the stick.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external configuration diagram of a rechargeable stick type and handy type vacuum cleaner according to an embodiment of the present invention, and FIG. 1A is an external configuration diagram of a handy type vacuum cleaner 1. FIG. 1B is an external configuration diagram of the stick type vacuum cleaner. 2 is a cross-sectional view of the hand-held vacuum cleaner of FIG. 1A, FIG. 3 is a cross-sectional view of the stick-type vacuum cleaner of FIG. 1B before assembly, and FIG. 4 is after the stick-type vacuum cleaner is assembled. FIG.

  A handy type vacuum cleaner 1 shown in FIG. 1A is a substantially box-type vacuum cleaner that lifts a vacuum cleaner body and moves the vacuum cleaner body manually by hand, and extends in the front-rear direction. A main body 2, a floor brush 3 detachably attached to the front end of the cleaner body 2, and a handle 4 formed integrally with the rear end of the cleaner body 2 and distinguishable from the cleaner body 2. ing. The main body 2 can capture the dust sucked inside.

  The floor brush 3 is a substantially T-shaped member in plan view, and includes a casing 31 extending in the left-right direction and a hollow connecting vent 5 extending rearward from the central rear end of the casing. The handle 4 is a substantially disk-shaped member, and the inside of the disk is cut out by a semicircle having a diameter smaller than the diameter of the outer peripheral surface of the disk. A surface 42 is formed. The handle 4 is integrally formed so that the front end portion of the outer peripheral surface 41 is connected to the main body 2 so that the side view is circular (when the handle 4 is standing).

  On the outer peripheral surface 41 of the handle 4, a power source / connection changeover switch 43 for operating the handheld vacuum cleaner 1 is provided. The power switch controls the power supply to the motor of the electric blower by turning on / off the battery power. A stick insertion hole 44 is provided on the upper surface of the handle 4. The connection selector switch selectively switches the circuit connection for connecting an auxiliary battery, which will be described later, in series or in parallel to the battery. The switch display is, for example, “long” for long-time operation and powerful. In the case of driving, the driving mode can be displayed as “strong”.

  As a result, the user lifts the handheld vacuum cleaner 1 so as to grasp the outer peripheral surface 4 and the inner peripheral surface 42 of the handle 4, and further moves the portable vacuum cleaner 1 by turning on the power switch 43. Therefore, cleaning can be performed by sucking dust from the floor brush 3.

  In the stick-type vacuum cleaner 1 shown in FIG. 1B, a separately prepared stick 6 is assembled by inserting a stick insertion hole 44 provided on the upper surface of the handle 4. As a result, the user does not move the portable vacuum cleaner 1 by holding the grip 61 at the top of the stick 6 and lifting the stick vacuum cleaner 1 and then turning on the power switch 43. The dust can be sucked from the brush 3 for cleaning.

  The internal configuration of the handheld vacuum cleaner 1 will be described in detail with reference to FIG. The cleaner body 2 includes a front body 21 and a rear body 22. The front main body 21 has a hollow shape, and its rear surface is covered with a removable filter 23, thereby forming a dust collection chamber 24 therein. In addition, a suction nozzle 25 having a predetermined length is integrally provided with the front main body 21 at the front lower end portion of the front main body 21 and protrudes forward in a fixed cylindrical shape made of, for example, resin. .

  The nozzle discharge port of the suction nozzle 25 faces the dust collection chamber 24. Thereby, one air passage from the external space toward the dust collection chamber 24 is formed. The suction nozzle 25 is mainly used for cleaning a floor surface in a narrow space.

  The rear main body 22 has a hollow shape and incorporates a fan 7 for sucking air and a motor 8 for transmitting driving force to the fan 7. The fan 7 and the motor 8 serve as an electric blower. Constitute. The floor brush 3 includes a connection vent 5 connected to the rear end of the casing 31. A rotatable rotary brush 32 is provided in the casing 31 of the floor brush 3.

  The connection vent 5 is a cylindrical long member, and the front end of the connection vent 5 is pivotally connected to the casing 31 so that the connection vent 5 swings up and down around the front end. Thereby, the angular position of the casing 31 changes in the vertical direction with respect to the main body 2. Therefore, even if the position of the main body 2 moves up and down, the rotary brush 32 can be prevented from leaving the floor surface.

  The handle 4 incorporates four rechargeable series batteries 9 as a power source for driving the motor 8, and the battery 9 and the motor 8 of the main body 2 are connected by an electric circuit via a power source / connection changeover switch 43. Electrically connected. The power source / connection changeover switch 43 electrically connects and disconnects the battery 9 and the motor 8 and selectively switches the connection relationship with an auxiliary battery described later between series connection and parallel connection.

  A concave portion 44 for inserting a stick described later when used as a stick type vacuum cleaner is provided at the upper portion of the handle 4, and a terminal 10 (here, for connection with an auxiliary battery) is provided on the bottom surface of the concave portion 44. Male terminal) is formed. When the vacuum cleaner is used as a handy type vacuum cleaner, the terminals of the connection terminals 10 are connected. The lid 11 is inserted into the recess 44.

  Normally, when the power switch 43 is turned on with the floor brush 3 attached to the cleaner body 2, the motor 8 is driven and the fan 7 is rotated so that the air flows from the front to the rear of the fan 7. Occurs. As a result, an air flow (suction force) from the floor brush 3 into the dust collecting chamber 24 is generated, and when the floor brush 3 is landed, dust on the floor surface is sucked from the suction port, and the casing 31 It passes through the inside and the connection circle 5 (inside the suction nozzle 25), is captured by the filter 23 in the main body 2 (in the front main body 21), and is stored in the dust collecting chamber 24.

  On the other hand, when the floor brush 3 is removed from the vacuum cleaner main holiday 2 (front main body 21), the suction nozzle 25 appears, and along the corner of the floor, the dust present in the corner of the floor can be satisfactorily sucked. You can also.

  When using as a hand-held vacuum cleaner, the battery 9 is equipped with a battery of an appropriate capacity when used with a hand-held vacuum cleaner. When used as a stick type vacuum cleaner to clean a wide area, cleaning may not be completed even if the battery capacity is used up. In some cases, a battery for outputting a stronger suction force is required.

  Therefore, the present invention realizes a vacuum cleaner that can take a sufficient amount of time to use when a handy vacuum cleaner is used as a stick-type vacuum cleaner and can select to output a stronger suction force. To do.

  FIG. 3 shows a state diagram before assembling the stick type vacuum cleaner of the present invention. FIG. 3A is a cross-sectional view of the above-described handheld vacuum cleaner of the present invention, which will not be described in detail here. In the figure, the lid 11 is removed and a recess 44 for inserting the stick is ready to be a stick type.

  FIG. 3B shows the stick of the present invention. A grip 61 is provided at the upper part of the stick 6, and four series-connected batteries 12 are arranged inside the hollow. A connection terminal 13 (in this case, a female terminal) serving as a connection circuit for the battery 4 is provided below the stick 6.

  When assembling the stick-type vacuum cleaner, the lower part of the stick 6 in FIG. 3B is inserted into the recess 44 provided in the upper part of the handle 4 of the vacuum cleaner 1 shown in FIG. The male terminal 10 and the female terminal 13 of the battery 12 are fitted together to form a battery connection circuit. FIG. 4 shows the state of the stick-type vacuum cleaner that has been assembled.

  When used as a stick-type vacuum cleaner to clean a wide area, the four batteries 12 inside the stick 6 are mounted. When the stick 6 is attached (inserted) to the cleaner body 2, the vacuum cleaner It is connected to the battery 9 inside the main body 2 and becomes a stick type vacuum cleaner equipped with a total of eight batteries.

  In order to prevent a situation in which cleaning cannot be completed even if the battery is used up, the connection switch of the power / connection selector switch 43 is connected to the four batteries 9 in the cleaner body 2. In order to connect the four batteries 12 in the stick 6 in parallel, the switch display is switched to, for example, “long” representing long-time operation.

  Next, when the power switch is turned on to turn on the battery power and the power supply to the motor of the electric blower is started, the battery 9 inside the cleaner body 2 and the battery 12 inside the stick 6 are connected in parallel. The battery capacity increases twice, but since the supply voltage to the motor 8 is the same, the vacuum cleaner can be operated for a long time.

  If it is necessary to clean with strong suction depending on the type of dust, the connection switch of the power / connection switch 43 is set to the four batteries 9 inside the cleaner body 2 and the 4 inside the stick 6. In order to connect the battery 12 in series, the switch switching display is switched to, for example, “strong” representing strong operation.

  Next, when the power switch is turned on to turn on the battery power and the power supply to the motor of the electric blower is started, the battery 9 inside the cleaner body 2 and the battery 12 inside the stick 6 are connected in series. Since the battery voltage is doubled, the power consumption of the motor 8 is doubled, and the suction force can be increased accordingly.

  In the above embodiment, the battery 9 inside the vacuum cleaner body 2 and the battery 12 inside the stick 6 are switched in series / parallel connection by the connection changeover switch 43, thereby controlling the current supplied to the motor 8 and the length of the vacuum cleaner. Although time operation or strong operation was selected, it is not shown without switching the series / parallel connection of the batteries, but a known power supply control means is provided to control the current supplied to the motor 8 by the means, It is also possible to adopt a configuration in which the vacuum cleaner is operated for a long time or a strong operation.

  Next, another form of the stick type vacuum cleaner will be described. The stick type vacuum cleaner 1 of the type shown in FIG. 5 includes a vacuum cleaner body 2, a floor brush 3, a handle, a connection vent 5 and a stick 6, similar to the one shown in FIG. The structure and function of the brush 3 for use are the same as those shown in FIG.

  The portion different from that shown in FIG. 4 is that the stick 6 is entirely hollow, and the grip portion is also hollow and open. The lower end of the stick 6 has an opening, faces the dust collecting chamber 24, and the cleaner body 2 has a structure that allows the intake air from the floor brush 3 to pass through the opening at the lower end of the stick 6. A ball or roller 64 is swingably disposed at the lower end of the stick 6, and a ball or roller 65 is also swingably disposed at the lower portion of the cleaner body 2.

  In the normal state of use as shown in FIG. 5, the stick-type vacuum cleaner having such a configuration is such that the lower ball or roller 65 of the vacuum cleaner main body 2 does not block the air inlet 26 of the dust collecting chamber 24 and moves downward. positioned. On the other hand, the ball or roller 64 at the lower end of the stick 6 blocks the opening 63 facing the dust collecting chamber 24 at the lower end of the stick 6 and prevents the intake air from the floor brush 3 from passing through the opening 63 at the lower end of the stick 6. is doing. Thereby, all the dust and intake air from the floor brush 3 are collected in the dust collecting chamber 24 through the intake port 26 of the cleaner body 2.

  When this stick type vacuum cleaner is used for cleaning a narrow place or a place such as an air conditioner that is out of reach such as a high place or a push-in place, as shown in FIG. Hold the vacuum cleaner body 2 at hand and point the opening of the grip 6 of the stick 6 to the garbage. As a result, the ball or roller 65 at the lower part of the cleaner body 2 swings and moves to a position that closes the intake port 26 of the dust collecting chamber 24, and dust and intake air from the floor brush 3 is opened 51 and the intake port 26. It does not reach the dust collection chamber 24 directly through.

  On the other hand, the ball or roller 64 at the lower end of the stick 6 falls inside the stick 6 and is locked to the protrusion 66 formed inside the lower part of the stick 6. Thereby, the opening 63 facing the dust collecting chamber 24 at the lower end of the stick 6 is opened, and the intake air from the opening of the grip portion of the stick 6 passes through the gap of the projection 66 in the stick 6 and passes through the opening 63 at the lower end. All dust is collected in the dust collection chamber 24.

  In this way, during normal floor cleaning, the cleaner is operated using the stick portion as a grip and cleaned using the floor brush. Then, when cleaning a narrow gap between furniture or an air conditioner such as an air conditioner, change the stick part so that it faces the garbage and operate to suck the dust from the end of the grip.

  In the above-described embodiment, the balls or rollers 64 and 65 are used as means for closing the air inlet 26 of the dust collection chamber 24 of the cleaner body and means for closing the opening 63 facing the dust collection chamber 24 at the lower end of the stick 6. As another embodiment, a control valve that slides instead of a ball or a roller will be described below with reference to FIGS. In this figure, the same components as those shown in FIGS. The control valve 67 is provided with an intake passage hole 68 in a part of the middle thereof, and slides by gravity.

  In the stick type vacuum cleaner of this embodiment, in a normal use state as shown in FIG. 7A, the control valve 67 slides as shown in the enlarged view of the control valve portion in FIG. 7B. By doing so, the opening 63 facing the dust collecting chamber 24 at the lower end of the stick 6 is closed, and the intake air from the floor brush 3 is prevented from passing through the opening 63 at the lower end of the stick 6. Further, an intake passage hole 68 of the control valve 67 is opposed to the opening 51 for intake from the floor brush 3 to form a vent hole. Accordingly, dust and intake air from the floor brush 3 is collected in the dust collection chamber 24 through the opening 51 and the intake port 26 of the cleaner body 2.

  When this stick type vacuum cleaner is used to clean a narrow place, or in places such as an air conditioner that are out of reach such as high places or indents, as shown in FIG. Hold the vacuum cleaner main body 2 at hand and turn the opening of the grip 6 part of the stick 6 toward the garbage. As a result, as shown in the enlarged view of the control valve portion in FIG. 8B, the control valve 67 slides and closes the opening 51 for intake from the floor brush 3, and dust from the floor brush 3. The intake air does not reach the dust collection chamber 24 through the opening 51 and the intake port 26.

  On the other hand, the opening 63 facing the dust collecting chamber 24 at the lower end of the stick 6 faces the intake passage hole 68 of the control valve 67. As a result, the intake air from the opening of the grip portion of the stick 6 passes through the stick 6, passes through the opening 63 at the lower end, and is collected in the dust collecting chamber 24.

  Normally, when using a hand-held vacuum cleaner and a stick-type vacuum cleaner, the movement of the vacuum cleaner will be different. Satisfactory operability could not be obtained. Therefore, FIG. 9 shows means for improving operability when the stick type vacuum cleaner of the present invention is used.

  In FIG. 9, the floor brush 3 is provided with a pivot mechanism that swings back and forth in the vent portion 5, and a stick 6 having a grip 61 is inserted and fitted into the upper portion of the vent portion 5. This state is the same as that of the conventional stick type vacuum cleaner. In this embodiment, a rotation mechanism is provided at the base 69 of the stick. Then, by operating the gripping hand 61 of the stick, for example, counterclockwise, the rear wheel of the floor brush 3 similarly turns counterclockwise. Thereby, the brush 3 for floors can rotate counterclockwise and can change the direction of cleaning.

  In other words, when used with a hand-held vacuum cleaner, a rotating mechanism with improved operability in the front-rear direction is required and is provided in the brush bend portion. And about the operativity of the rotation direction required by using with a stick type vacuum cleaner, it does not add the further rotation mechanism to the same brush bend part, but it provides by the base 69 of the stick 6, respectively. Independent operability can be obtained.
