Description

Electric vacuum cleaner

Technical Field

The invention relates to an electric dust collector.

Background

As a conventional electric vacuum cleaner, a product is commercially available in which a cyclone dust collecting unit is detachably mounted to a cleaner body.

Further, patent document 1 proposes that the cyclone dust collecting unit be attachable to and detachable from a unit housing section between the cleaner body and the suction port body.

In the electric vacuum cleaner disclosed in patent document 1, the unit accommodating portion is provided with a positioning protrusion and a locking recess for positioning the cyclone dust collecting unit.

On the other hand, the cyclone dust collecting unit includes a dust cup, a cover, an exhaust pipe, a filter screen, and a cleaning member, and a fitting recess fitted to the positioning protrusion is provided at the bottom of the dust cup. Furthermore, a locking lever is provided on the cover for fastening the cyclone dust collecting unit to the unit receiving portion. The lock lever is urged in a direction of being fitted in the locking recess of the unit housing portion through an urging member such as a spring.

According to the electric vacuum cleaner disclosed in patent document 1, the user pulls the lock lever downward to rotate the cyclone dust collecting unit forward around the positioning protrusion, thereby removing the cyclone dust collecting unit from the unit accommodating portion, and thus the garbage in the dust cup can be discarded. Conversely, when the cyclone dust collecting unit is mounted in the unit accommodating portion, the positioning convex portion is fitted into the fitting concave portion of the dust cup, the cyclone dust collecting unit is rotated toward the unit accommodating portion about the positioning convex portion, and the front end of the locking lever is locked in the locking concave portion, thereby fixing the cyclone dust collecting unit in the unit accommodating portion.

In addition, in the case of a conventional electric vacuum cleaner in which a cyclone dust collecting unit is detachably attached to a cleaner body, a cyclone dust collecting unit attachment portion having the same configuration as that of the unit housing portion described in patent document 1 is provided to the cleaner body.

Patent document 1 Japanese laid-open patent publication No. 2005-168775

Disclosure of Invention

In the case of the electric vacuum cleaner described in patent document 1, in order to attach the cyclone dust collecting unit to the unit accommodating portion, it is necessary to rotate the cyclone dust collecting unit toward the unit accommodating portion around the positioning portion as described above.

However, the cyclone dust collecting unit may be detached because the cyclone dust collecting unit is not attached to the unit accommodating portion according to the user's difference. Specifically, the fitting recess is not fitted into the positioning projection, and an erroneous mounting method is performed in which the cyclone dust collecting unit is pressed in parallel to the unit accommodating portion, which results in a poor mounting.

Such a mounting failure is also the same as in the conventional electric vacuum cleaner in which the cyclone dust collecting unit mounting portion is provided in the cleaner body. In particular, in the case of the electric vacuum cleaner and the hand-held electric vacuum cleaner described in patent document 1, since the position of the cyclone dust collecting unit is higher than the waist of the user during use, the cyclone dust collecting unit falls to the ground and is broken, and further, there is a fear that collected garbage is scattered indoors from the dust cup.

In view of the above problems, an object of the present invention is to provide an electric vacuum cleaner in which a dust cup unit can be easily and accurately attached to a cleaner body.

Therefore, the present invention provides an electric vacuum cleaner, which is characterized in that:

a dust collector body with a built-in electric blower, a dust cup unit detachably mounted on the dust collector body, a first locking mechanism and a second locking mechanism;

a cleaner body having a dust cup holding portion for detachably holding the dust cup unit;

the first and second lock mechanisms are contact portions which are disposed at one end portion and the other end portion opposite to the one end portion of the dust cup unit in a state where the dust cup unit is attached to the dust cup holding portion, and which are detachably fixed to two places of the dust cup holding portion which are in contact with the one end portion and the other end portion.

The electric vacuum cleaner of the present invention includes first and second lock mechanisms, each of which is detachably fixed to a contact portion at two positions of the dust cup holding portion, one end portion of the dust cup unit and the other end portion opposite to the one end portion, which are in contact with the one end portion and the other end portion. Therefore, the dust cup holder may be mounted in parallel or inclined, and the first and second lock mechanisms may function reliably, thereby preventing the dust cup unit from falling off the dust cup holder due to mounting failure.

The present invention is suitable for an electric vacuum cleaner of a cyclone dust collecting type.

Fig. 18 is a fourth explanatory view following fig. 17, in which (a) is a view corresponding to the arrow on the line II-II in fig. 2, and (B) is a view corresponding to the arrow on the line I-I in fig. 2.

As shown in fig. 5, 8 and 15(a) and (B), the first lid 13B of the battery lid 13B is provided with a first opening₁ Intermediate portion 13b of₁₁At a lower pressure than the press-in abutting portion 13b₁₁₂An L-shaped rib 13b is arranged at the lower rear part₁₁₃At this L-shaped rib 13b₁₁₃Forming a through hole 13b₁₁₄. The through hole 13b₁₁₄Locking member 13d described later₁So as to be able to be engaged and disengaged.

The locking member 13d₁A frame-shaped member slidable in the front-rear direction is provided in a space below the battery housing recess 13a in the case 11. The locking member 13d₁For sliding operation in the front-rear direction, the operating rod 13d is passed through the right connecting portion₂Is integrally formed. In addition, an inclined plate 13a in the battery housing recess 13a₁Is provided with a receiving portion for receiving the L-shaped rib portion 13b₁₁₃ U-shaped rib 13a of₁₃And in the inclined plate portion 13a₁And the U-shaped rib 13a₁₃Formed in the front-rear direction to pass through the locking member 13d₁Through hole 13a of₁₃₁。

In order to dispose the operation lever 13d2 between the battery storage recess 13a and the right side wall of the case 11, a locking member 13d1 is attached to the inside of the case 11, and a long hole 12b3 is formed above the exhaust port 12b2 in the right side wall of the case 11 so that the operation lever 13d2 is exposed to the outside. The engaging member 13d1 mounted in the housing 11 is passed through a compression coil spring 13d as a biasing member₂And is sprung backwards in a springing way.

The convex stopper boss 13e₁And a compression coil spring 13e₂Assembled together with the locking member 13d₁Is formed by a compression coil spring 13e₂Is sprung upward. Accordingly, the brake convex part 13e₁An inclined plate 13a inserted into the battery receiving recess 13a₁Hole part 13a of₁₂At the inclined plate part 13a₁Also protrudes above. Accordingly, the rear end of the battery 30 in the battery accommodating recess 13a is engaged with the stopper protrusion 13e₁The abutment restricts the rearward movement of the battery 30 when the user is not intended. In addition, because the brake convex part 13e₁Is connected with the inclined plate part 13a₁Hole part 13a of₁₂Is abutted against the peripheral portion of the stopper projection 13e₁Cannot pass through the hole 13a₁₂And pulling out the steel pipe upwards.

Fig. 1,5, and 6 show a battery mounted state of the electric vacuum cleaner 1 according to the present invention. At this time, the battery 30 is press-fitted into the plurality of terminal portions 43 in the battery mounting portion 13, and positive and negative terminals of the battery 30 are in electrical contact with the respective terminal portions 43. The battery cover 13b is a locking member 13d that is urged rearward₁Through an L-shaped rib 13b embedded in the battery cover 13b₁₁₃Through hole 13b₁₁₄And the closed state is maintained. In addition, a pair of right and left push-out abutting portions 13b of the battery cover 13b₁₂₁Are separated from the left and right protrusions 30a of the battery 30.

When the battery 30 is taken out, as shown in fig. 15(a) and (B), the user can operate the operating lever 13d with his/her finger₂Slide forward by resisting the compression coil spring 13d₃The spring force of (2) and the locking member (13 d)₁Move forward. Accordingly, the locking member 13d₁L-shaped rib 13b from battery cover 13b₁₁₃Through hole 13b₁₁₄And (4) disengaging. Then, the battery cover 13b is pressed upward by the compression coil spring 13b₅The battery cover 13b and the shaft portion 13b₃Is automatically rotated upward (in the direction of arrow A) about the center. Further, the release lever 13d₂When the pressure is applied, the pressure is transmitted through the compression coil spring 13d₃Spring force locking member 13d₁And moves backward (see fig. 19).

In addition, to the battery lid 13bWhen the slide projection 13b is rotated in the direction of arrow A₄Is directed to the inclined surface part 13c of the support member 13c₃And sliding upwards. At this time, the sliding protrusion 13b₄To smoothly follow the inclined surface part 13c₃Sliding, sliding convex part 13b₄Is formed in a shape having a convex curved surface.

FIGS. 15(A) and (B) show the penetrating compression coil spring 13B₅The first step of the opened state of the battery cover 13 b. In order to take out the battery 30, as shown in fig. 16 to 18(a) and (B), the battery cover 13B is opened more largely by the user (second step). This second step is to automatically assist the removal of the battery 30 through the next action.

First, as shown in fig. 16, as the battery cover 13b is rotated in the direction of arrow a, the pair of right and left pushing-out abutting portions 13b₁₂₁Rotated and abutted against the front ends of the left and right protrusions 30a of the battery 30. Then, as shown in fig. 17(a), a pair of right and left push-out contact portions 13b₁₂₁Further rotated, the pair of right and left push-out abutting portions 13b₁₂₁The left and right protrusions 30a of the battery 30 are strongly pressed backward by the principle of leverage. At this time, as shown in fig. 17(B), the stopper projection 13e comes to₁The vicinity is such that battery 30 moves backward and positive and negative terminals are separated from terminal portions 43.

Fig. 17(a) and (B) show a state in which the left and right protrusions 30a of the battery 30 are not yet completely inserted from the left and right guide grooves 13a₂₁Pulled out and passed through the stopper projection 13e₁The movement of the battery 30 in the backward direction is restricted. Therefore, even in this state, the tube 12a of the electric vacuum cleaner 1 is moved upward, and the battery 30 does not fall from the battery housing recess 13 a.

The battery cover 13b completely opens the left and right protrusions 30a of the battery 30 so as not to completely extend from the left and right guide grooves 13a₂After the battery 30 is pulled out, as shown in fig. 18(a) and (B), the user grasps and pulls the battery 30 backward with fingers. At this time, the rear end portion of the battery 30 is provided with an inclined surface, and the stopper projection 13e₁Has a circular front end and presses the stopper projection 13e through the rear end of the battery 30₁Front end portion of (3), brakeDevice convex part 13e₁Is pulled in downwards. This releases the restriction of the movement of the battery 30 in the backward direction.

In addition, fig. 17(a) and (B) show a state in which the positive and negative terminals of the battery 30 have been detached from the respective terminal portions 43 and the left and right protrusions 30a of the battery 30 are also detached from the left and right guide grooves 13a₂₁The force required to pull out the battery 30 backward is reduced by a certain degree of pull-out, and for example, even a female can pull out completely with a light force.

On the other hand, the battery 30 may be attached to the cleaner body 10 in a reverse operation to the operation of pulling out the battery 30 from the cleaner body 10. At this time, the brake convex part 13e is passed₁The battery 30 may be pushed into the battery housing recess 13a to such an extent that the battery 30 does not need to be completely pushed into the bottom of the battery housing recess 13a (see fig. 19). Furthermore, the battery 30 passes through the stopper projection 13e₁Because of the brake convex part 13e₁When the user jumps out, the user will have a "clattering" sound, and the user can have an operation feeling by hearing the sound.

As shown in fig. 19, when the battery cover 13B is rotated in the arrow B direction and closed, the press-in abutting portion 13B of the battery cover 13B₁₁₂The battery 30 is press-fitted forward while sliding on the circular rear end portion of the battery 30. Then, the battery cover 13b is completely closed, and the contact part 13b is pressed in₁₁₂The battery 30 is completely pressed into the bottom of the battery housing portion 13 a.

Accordingly, the positive and negative terminals of the battery 30 are in electrical contact with the respective terminal portions 43. In addition, at this time, the L-shaped rib 13b is lowered through the battery cover 13b₁₁₃And a locking member 13d₁The inclined surface of (2) is slidably engaged with and pulled into the locking member (13 d)₁Then, the light passes through the through hole 13b₁₁₄Locking member 13d₁The insertion is locked, maintaining the closed state of the battery cover 13 b.

< appearance >

In the electric vacuum cleaner 1 of the present invention configured as described above, as shown in fig. 1 and 2, the battery cover 13b of the battery mounting portion 13 is disposed on an extension line of the pipe portion 12a of the dust cup holding portion 12 extending in the front-rear direction, and the battery cover 13b is configured as a part of the pipe portion 12a to have an integral appearance. Further, the battery 30 is not exposed to the outside through the battery cover 13b, and a creative impression can be presented. Further, since the battery cover 13b is disposed on the upper side of the body, in the case of exchanging the battery 30, the battery cover 13b positioned on the upper side of the body is always visible, and this battery cover 13b becomes open, and the user can easily recognize and exchange the battery, compared with the case where the battery cover 13b is on the bottom side.

< action of electric vacuum cleaner >

When the electric vacuum cleaner 1 is used to clean a room, the electric blower M is driven by turning ON the switch 15a or the switch 15b of the operation unit 15, and dust, including dust, flows into the dust cup 21 through the inside of the pipe portion 12a of the cleaner body 10 as indicated by the thick arrow in fig. 5. The air containing dust flowing into the dust cup 21 rotates in the dust cup 21, and large dust is centrifugally separated to approach the bottom wall 21a of the dust cup 21 a.

As shown in fig. 5 and 9, in the air from which large dust is removed, dust larger than the meshes of the mesh filter screen 22b of the first filter screen unit 22 remains in the dust cup 21, and dust smaller than the meshes (mainly, dust) passes through the second filter screen unit 23 together with the air. Then, the small dust is caught in the filter main body 23a, and the air containing almost no dust flows into the electric blower 41 through the filter 23a, passes through the electric blower 41, and flows out of the exhaust port 12b₂And discharged to the outside.

(second embodiment)

Fig. 20 is a perspective view of a dust cup unit of a second electric vacuum cleaner according to an embodiment, and fig. 21 is a sectional view of the dust cup unit of fig. 20. In fig. 20 and 21, the same elements as those in fig. 1 to 19 are denoted by the same reference numerals.

The electric vacuum cleaner of the second embodiment is the same as the first embodiment except for the stopper protrusion 24f provided on the outer peripheral surface of the cup lid 24 of the dust cup unit 120.

The stopper projection 24f is engaged with the locking member 24c on the outer peripheral surface of the lid 24 in the vicinity thereofThe stopper 24c is disposed on and penetrates the compression coil spring 24c₃The opposite position of the spring. More specifically, the brake projection 24f is disposed to oppose the compression coil spring 24c₃When the biasing force of (c) is pushed into the locking member 24c along the maximum stroke in the direction of arrow J, the biasing force abuts against the position of the locking member 24 c.

By providing the stopper projection 24f, the following effects can be expected. That is, when the dust cup unit 120 is dropped on the floor surface and a strong impact in the direction of arrow J is applied to the locking member 24c, if the stopper protrusion 24f is not provided, the falling-off prevention rib (not shown) formed by the locking member 24c or the protrusion 24c of the rib via the locking member 24c₂The locking member 24c may come off due to the breakage caused by the strong impact. By providing the high-strength stopper projection 24f, even if a strong impact is applied to the locking member 24c in the direction of the arrow J, the strong impact is not transmitted to the falling-off preventing rib and the protrusion 24c₂But is received and stopped at the stopper projection 24f, so that the above-mentioned falling-off preventive rib and the projection 24c having low strength can be avoided₂And the locking member 24c is broken and falls off.

Further, since the stopper projection 24f is shaped like an isosceles triangle having a top in the direction of arrow J, when the dust cup unit 120 is taken out from the sweeper body 10, the user can operate the locking member 24c in the direction of arrow J to obtain the indicator effect.

(third embodiment)

Fig. 22 is a perspective view showing a cleaner body from which a battery is taken out in the electric vacuum cleaner of the third embodiment, and fig. 23 is a right side view showing a state in which a first cover member is taken out on the right side of the electric vacuum cleaner of the third embodiment. In fig. 22 and 23, the same elements as those in fig. 1 to 19 are denoted by the same reference numerals. The electric vacuum cleaner of the third embodiment is the same as the first embodiment in that the cooling air can be introduced into the battery mounting portion 13 of the cleaner body 110.

Specifically, as shown in fig. 5, 8, 22 and 23, the lower part of the battery mounting portion 13 in the case 11 isA storage space for the electric blower 41, the downstream side of the storage space and the inside of the battery mounting part 13 being a transparent air blowing port 13a₄₁But is communicated.

Therefore, the heated air is surely discharged from the discharge port by the flow of the permeated air through the heat of the battery 30 in the battery mounting portion 13.

Alternatively, the discharge port may be formed in the inclined plate 13a constituting the battery mounting portion 13₁So as to pass through the opening 13a of the terminal part 43₁₁A gap G between the terminal portion 43 and the terminal portion (see fig. 8) may be formed so that the discharged air passes through the gap G. In this case, the opening 13a₁₁Is preferably located on the upstream side of the storage space of the electric blower 41.

Further, the gap may be a gap generated in a state where the battery housing recess 13a and the battery cover 13b are combined.

Furthermore, in order not to let the air blowing port 13a₁₄And the discharge port is closed by the first lid part 13b1 of the closed battery lid 13b₁Is provided with a notch part 13b₁₃(refer to fig. 22).
