Electric sweeper

An embodiment of the present invention relates to an electric sweeper provided with a plurality of suction port bodies that are selectively connected so as to communicate with the suction side of the electric blower.

In the past, a canister electric sweeper or an upright electric sweeper generally adopts the following structure: In a normal operation mode, when the intake air volume of the electric blower is greatly reduced, the input of the electric blower is reduced. (Power down) to avoid overloading the electric blower due to the attachment of the suction mouth (floor brush) to the surface to be cleaned.

As the suction port body of such an electric sweeper, there are bedding brushes which can be used to remove fine dust (dust) such as mite debris or feces entering the bedding, or pollen. Such a bedding brush for bedding cleaning is provided with a casing and a suction opening opened in a lower portion of the casing, and is basically configured to adsorb a quilt fabric to the suction opening so as to suck not only dust adhered to the surface of the quilt fabric, Dust entering the back side of the quilt fabric is also sucked through the quilt fabric. Therefore, if the input control of the electric blower as described above is performed in the same manner as a normal suction inlet, the input is greatly reduced, and effective cleaning cannot be performed.

The problem to be solved by the present invention is to provide an electric sweeper with improved sweeping performance when the suction mouth body for sweeping a bedding is connected.

An embodiment provides an electric sweeper, which is characterized by comprising a sweeper body including an electric blower and a control unit that controls the operation of the electric blower; and a plurality of suction inlets to communicate with the electric blower. The suction side is selectively connected. The selectively connected suction port body includes a floor sweeping suction port body and a bedding sweeping suction port body. The bedding sweeping suction port body is inferior to the floor sweeping suction port body. The mouth body is suitable for cleaning a futon. When the suction mouth body for cleaning the bedding is connected, the control unit sets the electric blower to have a lower input than when the other suction mouth body is connected.

According to the embodiment, the electric blower is set to have a lower input than that when the suction port body for floor sweeping is used, so that problems such as a decrease in the sweepability of the suction port body for bedding sweeping or a driving noise roar can be improved, and the improvement can be achieved.

In addition, the ground contact detection member 37 may be omitted as necessary.

The connection pipe 32 communicates with the suction port 35. The connection pipe 32 is located at the rear of the casing 31, and the rear end side (downstream side) is detachably connected to the front end of the extension pipe 22 (FIG. 1 (a)). Therefore, the connection pipe 32 communicates the suction port 35 with the suction side of the electric blower 15 (FIG. 1 (a)). In addition, the connecting pipe 32 can pivotally support the front end side (upstream side) with respect to the housing 31.

On the other hand, the quilt brush 24 shown in FIG. 1 (b) can travel in the front-back direction on the part to be cleaned (futon (futon fabric)), and can be attached to and detached from the upstream end of the hose body 21 using the pipe section 13, That is, the handle operation portion 27. That is, the bedding brush 24 communicates with the dust collecting portion 18 (FIG. 1 (a)) through the hose body 21, and communicates with the suction side of the electric blower 15 (FIG. 1 (a)) through the dust collecting portion 18. Therefore, the quilt brush 24 sucks dust by driving the electric blower 15 (FIG. 1 (a)). In addition, the front-to-back direction and left-to-right direction (lateral direction, width direction) of the quilt brush 24 are based on the walking direction of the quilt brush 24, and the up-down direction is to place the quilt brush 24 on a flat floor surface. Anti-gravity direction and gravity direction in the state.

In addition, the quilt brush 24 is provided with a holding portion (a (third) front pressing portion) as a holding portion. Department 47.

The case 41 is formed of a synthetic resin or the like, for example, and is formed in a long side shape, that is, a horizontal length, in a direction crossing (orthogonal) to the running direction (front-rear direction) of the bedding brush 24 (the case 41), that is, the left-right direction. A (other) suction port 51 serving as a dust collecting port is provided in a lower portion of the casing 41 facing the quilt (futon fabric) in a long side in the left-right direction. The size of the suction port 51 in the front-back direction (short-side dimension) is smaller than that of the suction port 35 of the floor brush 23. The casing 41 is provided with a pressing portion such as a holding portion 47.

The connection pipe 42 communicates with the suction port 51. The connection pipe 42 is located at the rear of the housing 41, and the rear end side (downstream side) is detachably connected to the front end of the hose body 21 (the handle operation portion 27). Therefore, the connection pipe 42 communicates the suction port 51 with the suction side of the electric blower 15 (FIG. 1 (a)). In addition, the connecting pipe 42 can pivotally support the front end side (upstream side) with respect to the housing 41.

In addition, for the quilt brush 24, the suction port 51 is narrower in the front-rear direction (in the short-side direction) than the suction port 35 of the floor brush 23. The opening area of the suction port 51 is narrower than that of the suction port 35. The beater 45 or the like that pats the bedding is more suitable for cleaning the bedding than the floor brush 23.

Next, the internal structure of the electric cleaner 11 is demonstrated.

As shown in FIG. 4, the electric sweeper 11 includes an electric blower 15 and a control unit 16 that controls the operation of the electric blower 15. The electric sweeper 11 includes: (1) a control element 61 for controlling an input (power-on time or rotation speed) of the electric blower 15; and (2) a control element 62 for controlling a driving member of the floor brush 23 39 or the input of the vibration driving member 46 of the bedding brush 24. In this embodiment, for example, an external power source (commercial AC power source e) is used. Therefore, as the control element 61 and the control element 62, triacs are used. In addition, the control unit 16 is electrically connected to a setting button 29 of the handle operation portion 27, and is electrically connected to a ground contact detection unit 37 to detect the amount of intake air (blockage of the air path) of the electric blower 15 The detecting means (air volume detecting section) 63 and the type determining means (type determining section) 64 for determining whether the suction port body used for the pipe section 13 is the floor brush 23 or the bedding brush 24.

The air volume detection unit 63 may also use, for example, a current detection unit (current sensor) that detects the amount of intake air (clog on the intake side) by detecting the current flowing through the electric blower 15, for example. status). As this air volume detection means 63, other known arbitrary structures can be used.

The type determination unit 64 may also use a voltage detection unit (voltage sensor). The voltage detection unit (voltage sensor) may be, for example, a resistor R1 having a different resistance value from the floor brush 23 and the bedding brush 24. The connected resistor R2 detects the voltage generated by the divided voltages of the resistors R1 and R2 to determine whether the floor brush 23 or the bedding brush 24 is connected. As the type determination unit 64, any other known arbitrary structure can be used.

In the present embodiment, the control unit 16 switches the control element 61 on and off according to the operation mode set by the setting button 29 with a preset duty ratio (on-off ratio of the on-time), thereby The input of the electric blower 15 is changed. The operation mode of the electric blower 15 set by the control unit 16 includes, for example, in this embodiment, an operation mode for a floor brush (for floor cleaning) when the floor brush 23 is used, and a bedding brush when the bedding brush 24 is used. Use (for futon sweeping) operation mode.

The floor brush operation mode includes a strong mode as a first mode, a weak mode as a second mode, and an energy saving (ECO) mode as a third mode.

The strong mode is, for example, a mode used when a strong suction force is required such as cleaning of a carpet. In this strong mode, the control unit 16 sets the input of the electric blower 15 higher than the weak mode, the energy saving mode, and the operation mode for bedding brushes. Further, in this strong mode, the control unit 16 is provided with reference to the intake air volume (clogged state) detected by the air volume detection unit 63. The first control section corresponds to the intake air volume when the intake air volume falls below a predetermined value. The second control interval, when the intake air volume is lower than that of the first control interval, the input does not increase the input if the prescribed input is reached; and the third control In the section, when the intake air volume is reduced compared to the second control section, the input is significantly reduced (power is reduced). For example, in this third control section, the control unit 16 reduces the input of the electric blower 15 to a level lower than the input for the bedding brush operation mode and higher than the weak mode. Therefore, in the strong mode, for example, when a predetermined amount of dust is stored in the dust collecting portion 18, when the dust collecting portion 18 is clogged, or when the floor brush 23 (suction port 35) is adsorbed, When there is paper, etc., and the suction port 35 is substantially closed, such as when the suction air volume is reduced, the control of the control unit 16 is advanced from the first control section to the second control section and the third control section, so that the input of the electric blower 15 is suddenly reduced. .

The weak mode is, for example, a mode that is used when the sweeping sound is suppressed and quiet sweeping is performed. In this weak mode, the control unit 16 sets the input of the electric blower 15 to be lower than the strong mode and the operation mode for bedding brushes, and does not change the input based on the detection by the air volume detection unit 63. That is, in this weak mode, the control unit 16 does not reduce the input even if the intake air volume of the electric blower 15 is reduced to a predetermined value or less.

The energy saving mode is also called an automatic mode, and is a mode used when suppressing power consumption during cleaning. In this energy-saving mode, the control unit 16 switches as follows: When it is determined by the ground contact detection unit 37 that the floor brush 23 has touched the floor surface, the first energy-saving mode selected as the first automatic mode is selected, and When the detecting means 37 determines that the floor brush 23 has left the floor surface, it selects the second energy-saving mode as the second automatic mode.

In the first energy saving mode, the control unit 16 is provided with reference to the intake air volume detected by the air volume detection unit 63. In the first control section, when the intake air volume falls below a predetermined value, input is made in response to the decrease in the intake air volume. Sequentially set higher; and in the second control section, when the intake air volume is lower than that in the first control section, the input is greatly reduced. For example, in the second control section, the control unit 16 reduces the input of the electric blower 15 to a level lower than the input for the bedding brush operation mode and higher than the weak mode. Therefore, in the first energy saving mode, for example, when a predetermined amount of dust is stored in the dust collecting section 18, when the dust collecting section 18 is clogged, or when When the plate brush 23 (suction port 35) absorbs paper and the like and the suction port 35 is substantially closed, such as when the suction air volume is reduced, the control is advanced from the first control section to the second control section to reduce the input of the electric blower 15 suddenly. .

In the second energy-saving mode, the control unit 16 sets the input of the electric blower 15 to be lower than the strong mode, the weak mode, and the bedding brush operation mode, and does not change the input based on the detection by the air volume detection unit 63. That is, the second energy-saving mode is a mode in which the input of the electric blower 15 is set to the minimum, and even if the intake air volume of the electric blower 15 is reduced to a predetermined value or less, the control unit 16 does not reduce the input. In addition, this second energy-saving mode can also be used as a mode selected when neither the floor brush 23 nor the bedding brush 24 is used, but dust is directly sucked in from the front end side of the extension pipe 22 or the hose body 21, or connected When sucking dust from other suction nozzles, such as a crane nozzle (slit nozzle).

On the other hand, in the bedding brush operation mode, the control unit 16 sets the input of the electric blower 15 to the first energy saving mode (the first control interval and the second control interval of the strong mode) and the first energy saving mode of the energy saving mode ( The first control interval of the first energy-saving mode) is higher than the weak mode and the second energy-saving mode, and the input is not changed in accordance with the detection value of the air volume detecting means 63. That is, in this operation mode for a bedding brush, even if the amount of suction air of the electric blower 15 is reduced to a predetermined value or less, the control unit 16 does not reduce the input. Therefore, in this operation mode for bedding brushes, the input of the electric blower 15 is substantially constant. In other words, in this bedding brush operation mode, the input of the electric blower 15 is increased or decreased by the control unit 16, or is not increased or decreased by the control unit 16. Therefore, the number of electric blowers 15 in the operation mode for bedding brushes is increased or decreased. The amplitude, that is, the difference between when the input of the electric blower 15 is increased to the maximum and when it is decreased to the minimum is smaller than the increase or decrease of the input of the electric blower 15 in the floor brush operation mode (strong mode and first energy saving mode).

For example, FIG. 5 shows examples of input P1 in the strong mode, input P2 in the weak mode, input P3a of the first and second energy-saving modes of the energy-saving mode, input P3b, and input P4 of the operation mode for bedding brushes. In the input P1, P11 indicates a first control interval, P12 indicates a second control interval, and P13 indicates a third control interval. In the input P3a, P3a1 indicates a first control interval, and P3a2 indicates a second control interval.

Next, a sweeping operation of the electric sweeper 11 according to the embodiment will be described.

When cleaning, the user first connects the hose body 21 to the main body suction port 19 of the cleaner body 12 via the connection pipe portion 26. When cleaning the floor, the extension tube 22 and the floor brush 23 are sequentially connected to the handle operation portion 27 (FIG. 1 (a)) on the front end side of the hose body 21, and when cleaning the bedding, The quilt brush 24 is connected to the handle operation portion 27 on the front end side of the hose body 21 (FIG. 1 (b)). Therefore, the connection pipe 32 (suction port 35) of the floor brush 23 or the connection pipe 42 (suction port 51) of the bedding brush 24 communicates with the suction side of the electric blower 15.

Then, the floor brush 23 is placed on the floor surface, or the bedding brush 24 is placed on the bedding, and the power supply unit (for example, a commercial AC power source e) can be used to supply power to the control unit 16 and the electric blower 15, When the user holding the grip portion 28 operates a predetermined setting button 29, the control unit 16 In the case, the operation mode set by the setting button 29 is selected from the operation modes for the floor brush to control the input of the electric blower 15. When the bedding brush 24 is connected, the operation mode for the bedding brush is selected to control the electric blower 15. input of.

When the floor brush 23 is used, the user moves the floor brush 23 back and forth on the floor surface, thereby utilizing the effect of negative pressure generated by the driving of the electric blower 15 from the suction port on the front side of the floor brush 23 35 Inhale dust with air. The user appropriately rotates the rotating brush 36 according to the type of the floor surface. At this time, when the user operates a predetermined setting button 29, the driving member 39, which is supplied with power from the cleaner body 12 side via wiring, is driven via the control element 62 in response to the operation of the setting button 29, so that the rotary brush 36 is driven at a high speed Rotate it to remove dust from the floor surface or to clean the floor surface.

On the other hand, when the quilt brush 24 is used, the user drives the vibration driving member 46 to move the beater 45 up and down as necessary while the quilt brush 24 alternately walks on the quilt (futon fabric) in the front-back direction and the like. Therefore, the dust entering the inside of the quilt B is captured, and the negative pressure generated by the driving of the electric blower 25 is used to suck the dust together with the air from the suction port 51. At this time, the quilt brush 14 presses the quilt (futon fabric) in front of the suction port 51 by the front wheels 43 on both sides, the holding portion 47, and the tapper 45 in the protruding state when the quilt brush 14 moves forward and backward. The rear wheel 44 presses the quilt (futon fabric) behind the suction port 51, thereby pressing the quilt (futon fabric) downward along the suction port 51 before and after the suction port 51, so that the periphery of the suction port 51 The degree of vacuum is increased. In this state, negative pressure acts on the front wheel 43, the holding portion 47, the tapper 45, and the rear wheel 44 in a protruding state. The suction inlets 51 slightly above the respective lower end portions allow the bedding material to be adsorbed to the inner cotton of the bedding only within a narrow range corresponding to the position of the slit-shaped suction inlet 51 narrowed in the front-rear direction. Lift it slightly upwards to keep the bedding fabric away from the inner cotton upwards, creating a gap. Therefore, the negative pressure generated by the suction port 51 passing through the quilt fabric causes the gap to generate the suction wind that flows along the longitudinal direction of the suction port 51, that is, to the left and right direction center of the suction port 51, and enters. The fine dust of the inner cotton is sucked in together with the dust adhered to the surface of the bedding material through the breathable bedding material.

In addition, the air sucked in together with the dust by the floor brush 23 or the bedding brush 24 becomes a suction wind, and is sent from the main body suction port 19 to the dust collection part 18 through the pipe part 13, and the dust collection part 18 collects the dust.

Subsequently, the dust-removed suction air is sucked into the electric blower 15 and becomes exhaust air through the electric blower 15, and is discharged to the cleaner body 12 from an exhaust port (not shown) provided at the rear of the cleaner body 12 or the like. external.

When the electric sweeper 11 is housed when the cleaning is completed, the control unit 16 stops the electric blower 15 by operating the setting button 29. At this time, when the rotating brush 36 or the beater 45 operates, the operations of the rotating brush 36 and the beater 45 also stop.

Specifically, if the control of the control unit 16 is described with reference to the flowchart shown in FIG. 6, the control unit 16 that can supply power from the power supply section first determines whether or not a setting operation by the setting button 29 is performed (step 1). In this step 1, when it is determined that the setting operation is not performed, the process returns to step 1 and when it is determined that the setting operation is performed. In the case of operation, the control unit 16 determines the connected suction port body by the type determination unit 64 (step 2).

When it is determined in this step 2 that the floor brush 23 is connected, the control unit 16 selects an operation mode for the floor brush set by the setting button 29 in step 1 (step 3), and causes the electric motor to operate in this operation mode. The blower 15 operates. That is, the control unit 16 operates the electric blower 15 in one of a strong mode, a weak mode, or an energy saving mode (a first energy saving mode or a second energy saving mode).

In this floor brush operation mode, the control unit 16 determines the connected suction port body by the type determination unit 64 (step 4). When it is determined in this step 4 that the floor brush 23 is connected, that is, it is determined that the connection of the floor brush 23 is maintained, the control unit 16 determines a setting operation of the setting button 29 (step 5). When it is determined in this step 5 that there is no setting operation, the process returns to step 4. When it is determined in this step 5 that a setting operation for changing the operation mode of the electric blower 15 is performed, the process returns to step 3. Furthermore, in step 5, when it is determined that the stop operation is performed, the control unit 16 stops the electric blower 15 (and the drive unit 39) (step 6), and ends the control.

When it is determined in step 2 that the bedding brush 24 is connected, and in step 4 that it is determined that the bedding brush 24 is connected, that is, when it is determined that the floor brush 23 has been replaced with the bedding brush 24, the control unit 16 selects The bedding brush operation mode (step 7), in which the bedding brush operation mode is used to operate the electric blower 15.

In this bedding brush operation mode, the control unit 16 determines the connected suction port body by the type determination unit 64 (step 8). In step 8, in determining When the floor brush 23 is connected, that is, when it is determined that the quilt brush 24 has been replaced with the floor brush 23, the control unit 16 selects a predetermined floor brush operation mode (step 9), and the electric blower 15 is operated in this operation mode. Action and proceed to step 5. The operation mode selected in step 9 may be any of a strong mode, a weak mode, and an energy-saving mode (a first energy-saving mode or a second energy-saving mode).

When it is determined in step 8 that the bedding brush 24 is connected, that is, it is determined that the connection of the bedding brush 24 is maintained, the control unit 16 determines whether or not a stop operation is performed by the setting button 29 (step 10). If it is determined in this step 10 that the stop operation has not been performed, return to step 8. If it is determined that the stop operation has been performed, proceed to step 6 to cause the electric blower 15 (and the beater 45 (vibration drive member 46)). ) Stop and end the control.

In addition, when the floor brush 23 and the bedding brush 24 are replaced, the state of the suction port body is temporarily left. Therefore, during this period, the control unit 16 may set the operation mode of the electric blower 15 to the second energy-saving mode, for example.

As described above, when the floor brush 23 is used for cleaning, the dust is directly sucked together with the air by the negative pressure acting from the suction port 35. Therefore, in consideration of the operability or overload of the electric blower 15, when the cleaning target or other objects are attracted to the suction port 35 and the intake air volume is reduced, the input of the electric blower 15 is drastically reduced. The ease of cleaning using the floor brush 23 is optimized. On the other hand, when the quilt brush 24 is used for cleaning, the quilt fabric is actively attracted to the suction port 51 with a relatively weak suction force, and the suction wind is caused to flow to the back side of the quilt fabric to Inhale dust. So in making In the case of cleaning with the bedding brush 24, if the input control of the electric blower 15 similar to that of the floor brush 23 is performed, the control unit 16 will reduce the Input, and when the bedding material leaves the suction port 51, the control unit 16 raises the input of the electric blower 15. Therefore, the suction air cannot flow to the back side of the quilt in a state where the quilt fabric is attracted to the suction port 51, so that the sweepability of the quilt brush 24 is easily reduced, or the input of the electric blower 15 is frequently increased and decreased to drive. Sound roar and other adverse conditions. Therefore, according to an embodiment described above, when the bedding brush 24 for bedding sweeping is connected to the control unit 16, the electric blower 15 is set to have a lower input than that when the bedding brush 23 is connected, thereby enabling the already-used use. Input control of the electric blower 15 optimized for cleaning the bedding brush 24. As a result, the sweepability when the floor brush 23 for cleaning the floor is connected is not reduced, and the sweepability when the quilt brush 24 for cleaning the quilt is connected can be improved.

Specifically, when the bedding brush 24 for bedding cleaning is connected to the control unit 16, the electric blower 15 is set to have a lower input and a smaller increase and decrease than the case when the bedding brush 23 is connected, thereby making it possible to make the bedding fabric effective. The suction is maintained while being sucked to the suction port 51, so that the cleaning performance when the quilt brush 24 for cleaning the futon is connected can be improved.

In this embodiment, when the bedding brush 24 for bedding cleaning is connected to the control unit 16, the input is not reduced even if the suction air volume of the electric blower 15 drops below a predetermined value, thereby ensuring that the bedding brush 24 for bedding cleaning is connected. At the time, the input control of the electric blower 15 becomes easier.

In addition, the bedding brush 24 is provided with a beater 45 that applies vibration to the bedding. When the beater 45 is driven, the interval between the bedding fabric and the suction port 51 of the bedding brush 24 is periodically patted by the beater 45. The change causes a change in the degree of vacuum at the suction port 51. Therefore, if the input control of the electric blower 15 is performed in the same manner as the floor brush 23, a problem that the control unit 16 increases or decreases the input of the electric blower 15 in accordance with the change in the degree of vacuum is likely to occur. Therefore, as described above, when the bedding brush 24 provided with the beater 45 is used, the control unit 16 selects an operation mode for the bedding brush, thereby suppressing the change in the degree of vacuum generated by the driving of the beater 45 from affecting the electric power. The effect of the change in the input of the blower 15 can also be used to remove dust from the quilt by the beater 45, thereby performing more effective cleaning.

In addition, in the above-mentioned one embodiment, instead of the ground contact detection unit 37, a dust amount detection unit (dust amount detection) for detecting the amount of dust sucked in by the drive of the electric blower 15 may be connected to the control unit 16. unit). In addition, the first energy saving mode may be switched when the amount of dust detected by the dust amount detecting means is larger than a predetermined value, and the second energy saving mode may be switched when the amount of dust is smaller than the predetermined value. Furthermore, it is possible to provide both the ground contact detection means 37 and the dust amount detection means.

Furthermore, in the operation mode for bedding brushes, the control unit 16 performs control so as not to reduce the input even if the intake air volume of the electric blower 15 is reduced. A small increase or decrease is required to increase or decrease the input.

Furthermore, the operation mode for a bedding brush is set independently of the operation mode for a floor brush, but for example, the operation mode for a floor brush may be used instead of the operation mode for a bedding brush. Weak mode or energy saving mode.

Further, a configuration using a battery (secondary battery) as the power supply unit may be employed. At this time, as the control element 61, an arbitrary switching element is used instead of a triac, and the same time can be achieved by controlling the energization time from the battery to the electric blower 15.

Furthermore, the electric sweeper 11 is not limited to the horizontal type. For example, a vertical type in which a lower end portion of the sweeper body 12 having a long side in the up-down direction is selectively connected to a floor brush 23 or a bedding brush 24 may be correspondingly applied. use.
