FIG. 6 is a plan sectional view showing the suction chamber of the station unit according to the embodiment of the present invention.

FIG. 7 is a plan sectional view showing another example of the second suction port of the station unit according to the embodiment of the present invention.

FIG. 8 is a plan sectional view showing another example of the second suction port of the station unit according to the embodiment of the present invention.

FIG. 9 is a plan sectional view showing another example of the second suction port of the station unit according to the embodiment of the present invention.

As shown in FIGS. 6 to 9 in addition to FIG. 5, the wall surface 27 a of the second main body case 27 of the station unit 5 according to the present embodiment has a substantially planar first wall surface 78 and a first wall surface 78. Has a deformed second wall surface 79. The second suction port 26 includes a first opening 81 provided in the first wall surface 78 and a second opening 82 provided in the second wall surface 79.

The “deformed shape” here is a shape that is continuous with the first wall surface 78 and is not the same plane, for example, a plane that forms an angle greater than zero with the first wall surface 78, the first wall surface 78. It includes a flat surface that is connected stepwise, a curved surface that is continuous from the first wall surface 78, and a discontinuous curved surface.

Specifically, the second wall surface 79 has an arcuate outer shape in plan view (FIG. 6 ). The second wall surface 79 may have a stepped outer shape in plan view (FIG. 7 ). The second wall surface 79 may have a planar outer shape that makes an angle with the first wall surface 78 in a plan view (FIG. 8 ).

Further, the wall surface 27a may include a boundary wall 83 that divides the first opening 81 and the second opening 82 (FIG. 9). In this case, the station unit 5 may include an opening/closing valve 85 that opens the second opening 82 by negative pressure when the first opening 81 is closed (FIG. 9). The on-off valve 85 closes the second opening 82 with an elastic body (not shown) such as a spring when the air flows through the first opening 81 smoothly, and efficiently sucks negative pressure into the first opening 81. On the other hand, when the negative pressure in the suction air passage 66 becomes higher than a predetermined threshold value due to the first opening 81 being blocked, the second opening 82 is opened against the elastic body, and suction is performed. Air is introduced into the air passage 66. The on-off valve 85 itself may be deformed using an elastic body such as rubber.

The second suction port 26 is a means other than the autonomous cleaning unit 2, for example, dust collected by a mop, a broom, a cleaning tool such as a floor cleaning tool, or cleaning of a mop, a broom, a floor cleaning tool, or the like. Since the dust attached to the tool itself is directly sucked, when the cleaning tool is larger than the width dimension of the second suction port 26, the cleaning tool is sucked by negative pressure and the second suction port 26 is closed. There is a risk. If the second suction port 26 is blocked, the air flow (swirl flow) in the second dust collecting container 28 is weakened or disappears, and the dust separation performance of the second dust collecting container 28 deteriorates. Further, if the second suction port 26 is blocked, the second electric blower 29 may fall into an overload state due to idling, which is not preferable. Therefore, the electric cleaning device 1 according to the present embodiment avoids the second suction port 26 from being blocked by the suction tool by providing the second opening portion 82 on the second wall surface 79 that is different from the first wall surface 78. The separation performance of the second dust collecting container 28 is ensured, and the soundness of the second electric blower 29 is ensured.

Further, the electric cleaning device 1 is provided with the opening/closing valve 85, so that when the air circulation in the first opening 81 is secured, the second opening 82 is closed by the opening/closing valve 85 to reduce the suction negative pressure. By focusing on the first opening 81, the performance of removing dust from the cleaning tool can be improved.

The suction air passage 66 has an inflow side end portion 66a connected to the second suction port 26 and an outflow side end portion 66b having a width narrower than that of the second suction port 26. The suction air passage 66 is a funnel-shaped or fan-shaped air passage having a wide inflow side end 66a and a narrow outflow side end 66b.

The outflow side end portion 66b of the suction air passage 66 is biased to one side (here, the back surface 5a side of the station unit 5) of the center of the second suction port 26 in the width direction of the second suction port 26. .. In particular, the outflow side end portion 66b of the suction air passage 66 according to the present embodiment is located on either side of the center C1 of the second suction port 26 in the width direction of the second suction port 26 (here, the rear surface of the station unit 5). 5a side).

The outflow side end portion 66b and the inflow side end portion 66a of the suction air passage 66 are arranged so as to sandwich the second dust collecting container 28 in a plan view.

The station unit 5 also includes a plurality of dust removers 86 provided in the width direction of the second suction port 26.

The respective dust removers 86 are arranged above and below the second suction port 26 to divide the second suction port 26 in the width direction. There are, for example, five dust removers 86, and the second suction port 26 is divided into a plurality of, for example, six.

Each of the dust removers 86 has a front edge portion along the second suction port 26 and extends linearly from the inflow side end portion 66a to the outflow side end portion 66b. The distance W1 between the front edges of the adjacent dust removers 86, 86 among the plurality of dust removers 86 or the distance W1 between the dust remover 86 and the side edge 26a of the second suction port 26 is equal to the outflow side end of the suction air passage 66. It is set to be narrower than the width W2 of the portion 66b.

The front edge of each dust remover 86 abuts the suction tool when the cleaning tool is applied to the second suction port 26. When the suction tool addressed to the second suction port 26 is stroked in the width direction of the second suction port 26, each dust remover 86 scrapes off the dust adhering to the suction device to the second suction port 26. Induce.

By the way, in the electric cleaning device 1, when the outflow-side end portion 66b of the suction air passage 66 is clogged with a large amount of dust or large dust and the outflow-side end portion 66b of the suction air passage 66 is blocked, the second suction port is formed. Dust cannot be sucked in from 26. Therefore, the electric cleaning device 1 may block the outflow side end portion 66b of the suction air passage 66 by the plurality of dust removers 86 provided at intervals W1 narrower than the width W2 of the outflow side end portion 66b of the suction air passage 66. Some dust is prevented from flowing into the suction air passage 66.

Next, another example of the electric cleaning device 1 according to the embodiment of the present invention will be described. In addition, in the electric cleaning devices 1A, 1B, 1C and 1D described in each example, the same components as those of the electric cleaning device 1 are denoted by the same reference numerals, and overlapping description will be omitted.

FIG. 10 is an enlarged perspective view showing another example of the suction chamber of the station unit according to the embodiment of the present invention.

FIG. 11 is a plan sectional view showing the suction chamber of the station unit according to the embodiment of the present invention.

As shown in FIGS. 10 and 11, in the electric cleaning device 1A according to the present embodiment, the plurality of dust removers 86A provided in the width direction of the second suction port 26 and the suction air passage 66A in the width direction (inflow side end). A partition wall 87 is provided which divides the portion 66a and the outflow side end portion 66b into a line that intersects with the line.

Each dust remover 86A hangs downward from the upper edge of the second suction port 26 and separates a gap from the bottom side of the second suction port 26. There are, for example, five dust removers 86A, and the second suction port 26 is divided into a plurality of, for example, six. The plurality of dust removers 86A may protrude upward from the edge of the bottom side of the second suction port 26, and may have a gap from the upper side of the second suction port 26.

Each dust remover 86A has a front edge portion along the second suction port 26, and extends linearly from the inflow side end portion 66a to the outflow side end portion 66b. Of the plurality of dust removers 86A, the adjacent dust removers 86A, the spacing W1 between the front edges of the dust removers 86A, or the spacing W1 between the dust remover 86A and the side edge 26a of the second suction port 26 is the outflow side end of the suction air passage 66A. It is set to be narrower than the width W2 of the portion 66b.

The front edge portion of each dust remover 86A hits the suction tool when the cleaning tool is applied to the second suction port 26. When the suction tool addressed to the second suction port 26 is stroked in the width direction of the second suction port 26, each dust remover 86A scrapes off the dust adhering to the suction device to the second suction port 26. Induce.

The dividing wall 87 is bridged above and below the suction air passage 66A and extends linearly from the inflow side end 66a to the outflow side end 66b. The dividing wall 87 may reach the inflow-side end 66a of the suction air passage 66A to the outflow-side end 66b while avoiding the dust remover 86A, or may be separated from each end 66a, 66b.

That is, the dividing wall 87 does not have to reach the outflow side end 66b and be interrupted halfway from the inflow side end 66a of the suction air passage 66A toward the outflow side end 66b. Further, the dividing wall 87 may reach the outflow side end 66b at a distance from the inflow side end 66a of the suction air passage 66A. Furthermore, the dividing wall 87 may be arranged at an intermediate portion in the suction air passage 66A, apart from both the inflow side end portion 66a and the outflow side end portion 66b of the suction air passage 66A. In these cases, the dividing wall 87 may be on the extension line of the dust remover 86A.

Furthermore, the partition wall 87 may be integrally continuous with at least one of the plurality of dust removers 86A. In other words, at least one of the plurality of dust removers 86A may be integrally continuous with the dividing wall 87. 10 and 11 show a configuration in which the dividing wall 87 and the dust remover 86A are integrally continuous. 10 and 12 show a form in which the dust remover 86A hangs downward from the upper edge of the second suction port 26 and forms a gap with the bottom side of the second suction port 26.

There are a plurality of, for example, two dividing walls 87, and divides the suction air passage 66A into a plurality of, for example, three dividing air passages 88a, 88b, 88c. These divided air passages 88a, 88b, 88c are arranged in the width direction of the suction air passage 66A. The divided air passage 88a is close to the back side of the station unit 5, and the divided air passage 88c is close to the front side of the station unit 5, that is, the pedestal 19 to which the autonomous cleaning unit 2 returns and is connected. The divided air passage 88b is sandwiched between the divided air passages 88a and 88c, and is divided on both sides by dividing walls 87.

When there are a plurality of dividing walls 87, the distance W1 between the front edge portions of the adjacent dividing walls 87, 87, or the distance W1 between the dividing wall 87 and the side edge 26a of the second suction port 26, or the number of the dividing wall 87 is one. In this case, the interval W1 between the dividing wall 87 and the side edge 26a of the second suction port 26 is set to be narrower than the width W2 of the outflow side end portion 66b of the suction air passage 66A. Specifically, the space W1 between the outflow side ends 66b of the adjacent dividing walls 87, 87, or the space W1 between the outflow side end 66b of the dividing wall 87 and the side edge 26a (side wall) of the suction air passage 66A, or When the number of the dividing wall 87 is one, the distance W1 between the outflow side end portion 66b of the dividing wall 87 and the side edge (side wall) of the suction air passage 66A is equal to the width of the outflow side end portion 66b of the suction air passage 66A. Narrower than W2. In addition, "the interval W1 between the outflow side end portion 66b of the dividing wall 87 and the side edge 26a (side wall) of the suction air passage 66A" means the outflow side end portion 66b of the dividing wall 87 and the side edge 26a of the suction air passage 66A. It is the shortest distance from (side wall).

By the way, in the electric cleaning device 1A, when the outflow side end 66b of the suction air passage 66A is clogged with a large amount of dust or large dust and the outflow side end 66b of the suction air passage 66A is blocked, the second suction port Dust cannot be sucked in from 26. Therefore, in the electric cleaning device 1A, dust that may block the outflow-side end portion 66b of the suction air passage 66A by the partition wall 87 that is provided at the interval W1 narrower than the width W2 of the outflow-side end portion 66b of the suction air passage 66A. Are prevented from reaching the outflow side end portion 66b of the suction air passage 66A.

Further, in the case of dust whose volume can be reduced like cotton dust, the electric cleaning device 1A compresses the dust by the divided air passages 88a, 88b, 88c narrowing toward the outflow side end 66b of the suction air passage 66A. Then, the volume of dust is reduced and sent to the outflow side end portion 66b of the suction air passage 66A.

The partition wall 87 equalizes the negative pressure in the vicinity of the outside of the second suction port 26. Specifically, the dividing wall 87 is set so that the pressure loss in the central divided air passage 88b is higher than the pressure loss in the end divided air passages 88a and 88c.

Since the electric cleaning device 1 has the outflow side end portion 66b having a width narrower than that of the second suction port 26, the central portion (area A) of the second suction port 26, which is the front surface of the outflow side end portion 66b, is closer to the front side. However, the suction negative pressure is more likely to act than in the other portion (region B deviated from the front surface of the outflow side end portion 66b). In other words, in the electric cleaning device 1, the suction negative pressure is likely to act on the central portion (region A) of the second suction port 26, and the suction negative pressure acts on the end side (region B) of the second suction port 26. Hateful. Therefore, the electric cleaning device 1 sets the pressure loss of the central divided air passage 88b higher than the pressure loss of the divided air passages 88a and 88c on the side of the end so that the central portion of the second suction port 26 ( The suction negative pressure acting on the region A) is suppressed, and the suction negative pressure acting on the end side (region B) of the second suction port 26 is strengthened to substantially reduce the negative pressure near the outside of the second suction port 26. Equalize.

Further, there are a plurality of dividing walls 87, and at the outflow side end portion 66b of the suction air passage 66A, the air passage cross-sectional areas AaOut and AcOut of the end air passages 88a and 88c are the air passages of the central air passage 88b. It is set larger than the cross-sectional area AbOut.

The electric cleaning device 1 sets the air passage cross-sectional areas AaOut and AcOut of the divided air passages 88a and 88c on the end side to be larger than the air passage cross-sectional area AbOut of the divided air passage 88b on the center side, so that the second suction port is formed. The suction negative pressure acting on the central portion (region A) of 26 is suppressed, and the suction negative pressure acting on the end side (region B) of the second suction port 26 is strengthened to reduce the negative pressure near the outside of the second suction port 26. Substantially equalize the pressure.

Although the electric cleaning device 1 according to the present embodiment divides the suction air passage 66A into three divided air passages 88a, 88b, 88c, the suction air passage 66A includes four or more divided air passages (not shown). In the range where the negative pressure in the vicinity of the outer side of the second suction port 26 is substantially equalized, the air passage cross-sectional area of the divided air passage located at the end is on the central side. It does not necessarily have to be set larger than the cross-sectional area of the air passage. The electric cleaning device 1 according to the present embodiment has a wind that is smaller than the air passage cross-sectional area of the central air passage in the range that does not affect the substantially equalization of the negative pressure near the outside of the second suction port 26. It is not excluded that the divided air passage having the road cross-sectional area is provided at the end of the suction air passage 66A.

The plurality of divided air passages 88a, 88b, 88c divided by the dividing wall 87 have an air passage sectional area ratio (air passage sectional area AaOut: air passage sectional area AbOut: air passage sectional area AcOut) at the outflow side end portion 66b. The air passage cross-sectional area ratio (air passage cross-sectional area AaIn: air passage cross-sectional area AbIn: air passage cross-sectional area AcIn) at the inflow side end portion 66a is set to be substantially the same.

The electric cleaning device 1 sets the shapes of the divided air passages 88a, 88b, 88c by setting the air passage cross-sectional area ratio of the outflow side end portion 66b and the air passage cross-sectional area ratio of the inflow side end portion 66a to be substantially the same. The simplification and division of the suction air passage 66A by the linear dividing wall 87 are possible, and the prediction accuracy of analysis and the like is improved.

FIG. 12 shows a form in which the dividing wall 87 and the dust remover 86A are separated.

As shown in FIG. 12, the electric cleaning device 1B according to the present embodiment includes a suction air passage 66B.

The partition wall 87B of the suction air passage 66B is spaced apart from the dust remover 86A and the first opening 81 with a gap 89 communicating with the second opening 82, and the suction side (that is, the outflow) of the first opening 81. It extends toward the side end 66b).

In the electric cleaning device 1B, since the gap 89 between the front edge of the partition wall 87B and the dust remover 86A and the first opening 81 communicates with the second opening 82, the suction tool is installed in the first opening 81. When sucked, air is circulated from the second opening portion 82 to the gap 89 (flow indicated by a dashed arrow in FIG. 12) to reduce the negative pressure acting between the first opening portion 81 and the suction tool, The cleaning tool attached to the first opening 81 by negative pressure can be easily removed.

At the outflow side end 66b of the suction air passage 66C, the air passage cross-sectional area AcOut of the other end divided air passage 88c is set to be larger than the air passage cross-sectional area AaOut of the one end divided air passage 88a. There is. In other words, there is a relationship of (air passage cross-sectional area AcOut of divided air passage 88c)>(air passage cross-sectional area AaOut)>(air passage cross-sectional area AbOut).

In the electric cleaning device 1C, the outflow side end portion 66b of the suction air passage 66C is disposed on one side (here, the rear surface 5a side of the station unit 5) of the center of the second suction port 26 in the width direction of the second suction port 26. The divided air passages 88c on the other end side have a longer air passage length than the other divided air passages 88a and 88b. Therefore, the electric cleaning device 1C sets the air passage cross-sectional area AcOut of the divided air passage 88c on the other end side to be larger than the air passage cross-sectional area AaOut of the divided air passage 88a on the one end side, so that the air passage cross-section 88c is divided. The negative pressure acting on the divided air passage 88a is made stronger than the negative pressure acting on the divided air passage 88a to substantially equalize the negative pressure near the outside of the second suction port 26.

FIG. 14 is a plan sectional view showing another example of the suction chamber of the station unit according to the embodiment of the present invention.

Extends near. In this case, the divided air passage 88c reaches closer to the outflow side end portion 66b than the divided air passage 88a, and is more easily affected by the negative pressure.

In these electric cleaning devices 1, 1A, 1B, 1C, 1D, the relationship of the arrangement of the divided air passages 88a, 88b, 88c and the divided walls 87a, 87b is that the outlet side end with respect to the center of the second suction port 26. It depends on whether or not the portion 66b is biased in the width direction of the second suction port 26. That is, when the outflow side end portion 66b is offset to the other side (here, the front side of the station unit 5) from the center of the second suction port 26 in the width direction of the second suction port 26, the division is performed. The positional relationship between the air passages 88a, 88b, 88c and the dividing walls 87a, 87b is reversed.
