The front wall portion 56 is formed in front of the rotational axis of the rear wheel 44, the rear partition wall 55, the intake port 50, the holding portion 52, the beater 45 and the front wheel 43, (Not shown).

The deflecting means 57 applies a force to the beater 45 toward the downward protruding from the case body 41. The deflection means 57 is provided with a main body deflection portion 57a for applying a force to the beater main body 65 and a slider deflection portion 57b as a drive portion deflection portion for applying a force to the slider 66. [ As the deflecting means 57, a coil spring is used in the present embodiment, but other elastic bodies or the like may also be used. The main body deflecting portion 57a is attached to the case body 41 so that at least a part of the main body deflecting portion 57a is exposed to the beater attaching portion 51 and exerts downward force on both end portions in the longitudinal direction. The slider deflection portion 57b is attached to the case body 41 (the case portion 85) and applies a force to the slider 66 downward.

Next, the operation of the first embodiment will be described with reference to Figs. 1 to 6. Fig.

In cleaning, the rotary tube 42 of the bedding brush 14 is inserted and connected to the cleaner main body 12 (the connection portion 32 (main body connection port 38)) and is detachably held by the clamp 39 The bedding brush 14 communicates with the suction side of the electric blower 25 (through the main body connection port 38 and the dust collecting device 22).

 In the electric vacuum cleaner 11, the user who grasps the gripping portion 31 places the bedding brush 14 on the bedding sheet F of the bed B, and the setting button 36 provided on the holding portion 31, The control means 27 drives the electric blower 25 and drives the tapping drive means 63 as necessary to move the beater 45 upward and downward to move the bedding brush 14 in the up and down direction (FIG. 2 (a)) by using the negative pressure generated by the driving of the electric blower 25 by using the vertically moving motions of the beater 45 while alternately running in the forward and backward directions on the cleaning surface And sucks dust together with the air from the suction port (50).

The operation of the tapping drive means 63 at this time will be described. The tapping drive means 63 is configured to push up the beater 45 (slider 66) upward against the deflection by the deflection means 57 And is drawn into the inside of the case body 41). More specifically, the tapping drive means 63 rotates the rotary shaft 81a by driving the motor 81 by the control circuit C, and this rotation is transmitted to the cam 82 at a reduced speed through the belt 91 , The cam 82 rotates. This cam 82 is held in contact with the connection accommodating portion 75 of the slider 66 and the camshaft 82b by the deflection by the deflecting means 57. By the rotation of the cam 82, The camshaft 82b pushes up the slider 66 (the beater 45) against the deflection of the deflecting means 57 when the camshaft 82b moves from the lower side to the upper side The slider 55 (beater 45) is lowered by the deflection of the deflection means 57 (Fig. 1 (a)). As a result, the eccentric rotation of the camshaft 82b of the cam 82 rotated by the motor 81 causes the beater 45 to move up and down.

When the load is applied upward to the beater 45, for example, in the case where the beater 45 is pressed against the relatively hard blanket B, the beater 45 is moved by the deflecting means 57 (Imaginary line in FIG. 1A and FIG. 2 (A)), and the pushing force of the tapping drive means 63 The cam 82 (camshaft 82b) is not interlocked with the beater 45 (the connection accommodating portion 75 of the slider 66) at least a part (lower side) of its operation range (rotation area) The vertical movement of the beater 45 is restricted even when the driving means 63 is operating and the vertical movement of the beater 45 is restricted even when the tapping driving means 63 is stopped. The camshaft 82b of the cam 82 is spaced apart from the connection accommodating portion 75 of the slider 66 and enters the space portion 77 in a state of being pushed in against the deflection by the means 57 And the cam shaft 82b is brought into contact with the connection accommodating portion 75 only at the upper side of the rotation region and the beater 45 is pushed by a predetermined amount or more so that the connection accommodating portion 75 of the slider 66 is engaged with the cam 82, Even if the cam 82 rotates due to the rotation of the motor 81, the camshaft 82b is positioned at a position above the upper end of the rotational range of the camshaft 82b of the camshaft 82 (Fig. 1 (a) The range in which the beater 45 is interlocked is changed in accordance with the amount of movement of the cam 82 toward the upward direction of the beater 45 due to the suppression from the blanket B. [ In other words, since the amount of upward movement of the beater 45 depends on the hardness of the futon B, the cam 82 changes the range of interlocking the beater 45 in accordance with the hardness of the futon B. The cam 82 has a narrower range in which the beater 45 is moved upward as the blanket B is stiffer as the beater 45 is moved upward. The camshaft 82b is moved upwards by the knocking drive means 63 (in the retracted state) when the beater 45 is pushed upward (retracted state) Regardless of whether the motor 81 is driven or not, that is, whether or not the cam 82 is rotated by the motor 81, the beater 45 does not apply a load to the motor 81, The motor 81 can be pushed upwards by being suppressed by the cleaning unit such as the motor B and the up and down movement of the beater 45 is restricted without giving a load to the motor 81. [ In other words, even if the motor 81 (and the cam 82) is stopped at, for example, a certain position, the beater 45 can be pushed upward and can be pulled out of the tapping drive means 63.

The bedding brush 14 is connected to the suction port 50 by the front wheel 43, the holding portion 52, the front side wall portion 56 and the protruding beater 45 on both sides at the time of forward movement and backward movement, The blanket B (futon sheet F) is suppressed at the front of the suction port 50 by the rear wheel 44 and the blanket B (futon sheet F) is suppressed at the rear of the suction port 50 by the rear wheel 44, The blanket B (futon sheet F) is suppressed downward along the suction port 50 before and after the suction port 50 and the degree of vacuum around the suction port 50 is improved. In this state, a negative pressure acts on the suction port 50 located slightly above the lower ends of the front wheel 43, the holding portion 52, the protruding state beater 45, and the rear wheel 44, The futon sheet F is sucked in a narrow range only at a position corresponding to the narrow suction port 50 in the forward and backward direction of the shape and lifted up slightly against the batting I to form the futon sheet F on the batting I And the gap G is generated (Fig. 2 (b)). Thereupon, a suction air flowing to the center G of the suction port 50 in the left-right direction along the longitudinal direction of the suction port 50 in the gap G is generated by the negative pressure acting from the suction port 50 over the futon sheet F Fine dust that has entered the filling yarn I together with the dust attached to the surface of the futon sheet F such as carcasses or feces of finely crushed mites or pollen, Dust or the like is sucked through a futon sheet (F) having air permeability.

The dust-containing air sucked from the suction port 50 is conveyed to the dust collecting device 22 via the main body connection port 38 via the rotary pipe 42 and is separated from the air and collected. The dust-separated air is sucked into the motor-driven blower 25 to cool the motor-driven blower 25, and then exhausted to the outside of the cleaner main body 12 through a discharge port (not shown).

According to the embodiment described above, the rotational motion of the motor 81 is converted into the upward / downward motion of the beater 45, and the cam 45 is moved upward by the pressure from the blanket B, 82 are not interlocked with each other in at least a part of the operation range with respect to the beater 45 so that the bedding brush 14 is suppressed to the bedding B in the case of a relatively hard bedding B such as urethane The rotation of the motor 81 is not transmitted to the beater 45 in at least a part of the operating range even when the motor 81 (the tapping drive means 63) is driven by pushing up the beater 45, It is possible to limit the upward and downward movement of the arm 45. As a result, due to the vertical movement of the beater 45, the bedding brush 14 is hardly lifted from the bed B due to the repulsive force from the bedding B struck by the beater 45, The tapping method according to the hardness of the futon (B) can be applied.

At least a part of the beater 45 is held between the front wall 56 and the rear partition 55 and the rear wheel 44 by a holding portion 52 for suppressing the blanket B on the front and rear of the suction port 50 It is difficult for the beater 45 to swing the bedding brush 14 away from the blanket B even during driving of the motor 81 (the tapping drive means 63), and the holding portion 52, the front wall portion 56 The back side wall 55 and the rear side wheel 44 can surely suppress the bedding B and the lower portion of the bedding brush 14 (housing body 41) and the bedding B F) can be appropriately maintained and the suction force can be ensured.

The rotation of the motor 81 is converted into an operation of pushing up the beater 45 upward against the deflection of the deflecting means 57 by the cam 82 so that the beater 45 is moved upward It is possible to easily realize a configuration in which the cam 82 is not interlocked with the beater 45 in at least a part of the operating range.

Further, by using the cam 82 that eccentrically rotates by the rotation of the motor 81 as the conversion unit, the rotating operation of the motor 81 is performed by pushing up the beater 45 upward against the deflection of the deflection means 57 It is possible to easily realize a configuration for converting into an operation.

When the tapping drive means 63 is stopped, the beater 45 is pressed upward against the deflection of the deflecting means 57 to move the lower portion of the beater 45 toward the suction port It is possible to make the lowering of the suction force caused by the beater 45 in a state in which the operation of the tapping drive means 63 is stopped without using a complicated configuration with a simpler configuration .

The cam 82 as the conversion portion of the tapping drive means 63 is not interlocked with the beater 45 in a state in which the beater 45 is pushed upward by a predetermined amount or more by repression, The lower portion of the beater 45 can be easily positioned above the suction port 50 in a stopped state of the tapping drive means 63 without giving a load to the motor 81 via the suction opening 50. [

Specifically, the beater 45 can contact only the upper side of the cam 82 (camshaft 82b) that converts the rotational motion of the motor 81 as a drive source into the up and down operation and transmits it to the beater 45, Even if the motor 81 and the cam 82 are stopped at any position, the spacer 77 is pushed upward by pushing and moved The cam 82 can be easily and non-interlocked with the beater 45 in a state in which the cam 82 is moved by a predetermined amount or more.

By using the above-described bedding brush 14, the bedding brush 14 is hardly lifted from the bedding B due to the upward and downward movement of the beater 45, so that the workability of the cleaning is good and the hardness of the bedding B It is possible to provide the electric vacuum cleaner 11 capable of sweeping the beat of the beater 45 along with the dust,

In addition, in the first embodiment, as the converting section, an arbitrary structure such as a crank mechanism driven by a motor 81, for example, can be used in addition to the cam 82 rotating eccentrically.

The cam 82 of the tapping drive means 63 may be interlocked with the motor 81 in at least a part of the operating range in a state where the beater 45 is moved upward by the pressure. Concretely, a plurality of gears or the like are used as the transmission mechanism 84 for transmitting the rotation of the motor 81 to the cam 82 in place of the belt 91, for example, so that the beater 45 is moved upward And the cam 82 is also moved in conjunction with the movement of the motor 81 so that the gears are spaced apart from each other and the driving force from the motor 81 is not transmitted. That is, the cam 82 is moved so that the beater 45 is moved in the upward direction by the pressure from the blanket B and is not interlocked with at least one of the motor 81 and the beater 45 in at least a part of the operating range Can be configured.

7, the biasing means 57 may apply a force to the beater 45 upward against the case body 41. In this case, as shown in Fig.

Next, a third embodiment will be described with reference to Fig. The same components and operations as those of the above embodiments are denoted by the same reference numerals, and a description thereof will be omitted

In this third embodiment, the biasing means 57 of the first embodiment is not provided, and the tapping drive means 63 is kept at a position where the beater 45 is moved upward in the stopped state.

Specifically, in the third embodiment, the up and down movement of the biter 45 cooperates with the rotation of the cam 82, and the motor 81 stops in the retracted state of the beater 45 (slider 66) .

That is, the control circuit C controls the rotation position of the motor 81, that is, the rotation position of the cam 82 rotated by the motor 81, that is, Controls the camshaft 82b to detect the rotational position of the camshaft 82b so that the camshaft 82b is positioned near the upper side, specifically, the upper end of the rotational region when the motor 81 is stopped.

The connection accommodating portion 75 of the slider 66 is formed by vertically extending the camshaft 82b of the cam 82 up and down and elongating in the left and right direction, So that the slider 66 moves up and down integrally with the upward and downward movement of the camshaft 82b in accordance with the rotation.

As a result, when the tap driving means 63 stops, the lower portion of the beater 45 is positioned above the suction port 50 (the holding portion 52, the front wall portion 56, the rear partition wall 55 and the rear wheel 44) Even when cleaning the to-be-cleaned portion, which is difficult to obtain a repulsive force even if it is suppressed by the beater 45, such as a soft futon (B), for example, even when the futon brush 14 can be surely retreated upward without suppressing the beater 45 to the cleaning unit and the decrease in the suction force caused by the beater 45 in a state in which the operation of the tapping drive means 63 is stopped can be prevented It can be suppressed more reliably.

In each of the above-described embodiments, the bedding brush 14 may be cleaned in the same manner as the bedding B, for example, a cushion.

In addition to the battery 28, an external power source such as a commercial AC power source may be used as the power source of the electric vacuum cleaner 11. [

The bedpan brush 14 is connected to the separate cleaner main body 12 through the rotary tube 42 and the bedpan brush 14 to constitute the electric vacuum cleaner 11. The electric fan 11 25 can be knitted and the grip portion 31 can be provided on the case body 41 to constitute the electric vacuum cleaner 11. [

The suction port 50 may be provided in the beater 45. [

According to at least one embodiment described above, the holding portion 52 for pressing the blanket B before and after the suction port 50, the holding portion 52 for pressing the blanket B between the front wall portion 56 and the rear partition wall 55 and the rear wheel 44 The lower portion of the beater 45 in which at least a part of the beater 45 is positioned can be positioned above the suction port 50 in the stop state of the tapping drive means 63. Therefore, when the operation of the tapping drive means 63 is stopped It is possible to suppress the decrease of the suction force due to the beater 45 of FIG.

That is, it is preferable to fix the beater 45 (tapping drive means 63) so as not to damage the feathers when the batting I of the futon B is, for example, a soft feather or the like. When the lower portion of the beater 45 protrudes downward from the suction port 50 when the beater 45 (tapping drive means 63) is stopped as described above, the bobbin brush 14 (the case body 41) The gap between the lower portion and the blanket B (the futon sheet F) becomes large, which may lower the suction force. Thus, as described above, when the tapping drive means 63 is stopped, the lower portion of the beater 45 is positioned above the suction port 50, so that the lower portion of the bedding brush 14 (housing body 41) B) (the futon sheet F) can be appropriately maintained, so that the suction force can be ensured.

When the tap driving means 63 is stopped, the lower portion of the beater 45 is stopped at a position above the lower portion of the holding portion 52, the front wall portion 56, the rear partition wall 55 and the rear wheel 44 The operation of suppressing the blanket B from the front and rear of the suction port 50 by the holding portion 52, the front side wall portion 56, the rear side wall 55 and the rear wheel 44 is performed by the lower portion of the beater 45 The negative pressure can be reliably applied to the periphery of the suction port 50 without obstructing it.

By using the futon brush 14 as described above, it is possible to reduce the suction force caused by the beater 45 in the state in which the operation of the tapping drive means 63 is stopped, 11).
