Description

  TECHNICAL FIELD The present invention relates to a cleaner capable of separating solid and liquid to separate dry and wet after suction by suctioning the solid and liquid separately.

  When a solid object such as dust and a liquid such as accumulated water or waste liquid are simultaneously sucked, a dry vacuum cleaner becomes unusable when liquid droplets enter the motor part, and causes a problem that the filter corresponding to fine powder is clogged. . Further, in a wet vacuum cleaner, since a sponge-like or mesh-like liquid filter used therein has a large opening, it is inevitable that dust and the like sucked together with the liquid pass through without being caught. Was.

  Therefore, in addition to wet / dry machines that can be used separately for dry and wet applications by attaching / detaching a filter, etc., there are also vacuum cleaners that are both wet / dry machines.However, liquid separation is poor, and there is almost no example of a device that can suck liquid together with solid. . If solid and liquid are sucked without distinction, if a sludge-like substance adheres to the filter, it will take a lot of time and effort to clean, and the performance of the filter will not be completely restored and the performance of the vacuum cleaner will also be reduced It will be. In addition, if a vacuum cleaner is used with the filter closed, the motor may overheat due to the increase in resistance, causing burnout. This causes a problem of dispersing bacteria and molds throughout the room.

  In order to solve the above problem, Japanese Patent No. 4274957 is disclosed. This is a dry / wet dual-purpose vacuum cleaner having a suction chamber capable of vacuum suction without distinguishing between a solid and a liquid in a main body, and having a separation unit for separating a solid and a liquid from a suctioned material. It also has a thick and short cylindrical form, the axial length of which is smaller, the suction inner opening that opens to the suction opening that can simultaneously suck solids and liquids is opened on the peripheral surface, the upper end is the upper outlet, and the lower end is the lower end. A suction chamber serving as a lower outlet, a filter arranged around the suction chamber for separating fine dust contained in a flow passing through the upper outlet, and an upper part of the suction chamber where a suction object is vacuum suctioned A rectifying portion provided at the outlet and formed in a reverse taper shape to prevent the suction material from going directly to the upper outlet, and a taper shape provided at the lower outlet of the suction chamber to capture the collected material. At least two-stage cyclo formed Part, a bottomed tank structure formed at the lower part of the main body as a storage means for the collected matter caught in the cyclone part, and a flow that has been provided outside the suction chamber or the cyclone part and has flowed out of the upper outlet and the lower part. In addition to separating the flow exiting the outlet, the partition is provided with a partition wall serving as the bottom of an upper tank for storing collected matter separated from the flow exiting the upper exit.

  The wet / dry vacuum cleaner is capable of simultaneously sucking a solid object such as dust and a liquid such as accumulated water and waste liquid, and has been highly evaluated in the market. However, there is a further market demand for cleaners that can separate and recover solids and liquids.

The liquid storage section 40 includes a tank section 41 having a bottomed tank structure as storage means for storing liquid sucked from a liquid pipe 80 described later, and a tank mounted on an upper portion of the tank section 41. And an upper part 42. The tank portion 41 is detachably disposed from the tank portion upper portion 42. In addition, it is preferable that the solid storage unit 30 is disposed above the liquid storage unit 40. In general, the liquid tends to be heavier than the solid, and the lower the liquid storage part 40 storing the heavier liquid, the lower the position of the center of gravity is, and the stability of the cleaner 10 is maintained.

  Further, the cleaner 10 has a liquid suction pipe 85 in order to apply a suction force due to the suction airflow generated by the suction unit 20 to the liquid storage unit 40. The liquid suction pipe 85 is literally tubular, and one of the pipes is connected to the suction section 20 and the other is connected to the tank upper part 42 of the liquid storage section 40. Further, a super stop mechanism 400 having a float 401 (an overflow stopper at the time of sucking the liquid) is built in the tank upper part 42 to prevent intrusion of the liquid at the time of sucking the liquid and to form a mist. To prevent This prevents the mist of the liquid from entering the liquid suction pipe 85. The super stop mechanism 400 will be described later.

  One of the liquid pipes 80 is connected to the tank upper part 42 of the liquid storage part 40, and the other of the liquid pipes 80 is connected to the switching part 100. The switching unit 100 will be further described later.

  The solid storage section 30 stores the sucked solid, and is detachably disposed. The liquid storing section 40 stores the sucked liquid and is detachably disposed. As described above, since the liquid and the solid can be separated and stored, a user (not shown) can easily separate and collect the liquid and the solid, respectively.

  Further, the cleaner 10 includes the above-described solid pipe 70 and liquid pipe 80, and a switching unit 100 connected to a connection pipe 105 described later. The switching section 100 has a box-shaped switching box section 101, and the box-shaped switching box section 101 has a first wall section 102 that forms one end surface.

  One of the solid pipes 70 is connected to the solid storage unit 30, and the other is connected to the switching unit 100. The switching unit 100 is connected to the connection pipe 105. The connection pipe 105 is for detachably connecting the suction hose 160, and can suck a liquid or a solid from the suction hose 160.

Further, the switching unit 100 has a box-shaped switching box 101 having a rectangular parallelepiped shape, and the switching box 101 includes a first wall 102 constituting the surface thereof, and a first wall 102 And a second wall 103 disposed on a surface facing the second wall 103. Further, the first wall portion 102 has a solid pipe hole 102a having a hole shape in which the solid pipe 70 is arranged, and a liquid pipe hole 102b having a hole shape in which the liquid pipe 80 is arranged (FIG. 6A). reference). Further, a plate-shaped switching plate 110 that moves in parallel with the first wall 102 and a long hole 104 that is horizontally long in a front view are provided in the second wall 103.

  In addition, the switching unit 100 is disposed along the oblong hole 104 in front view, which is disposed on the second wall 103, and is disposed so as to cover the connection tube 105 movably to the left and right and the connection tube 105. Color 106. The collar 106 can also be moved together with the cylindrical connecting pipe 105 movably arranged along the elongated hole 104.

  The connection pipe 105 has a tubular connection pipe portion 105a and a connection member 105b for connecting to the suction hose 160. The suction hose 160 is inserted into the cylindrical connecting member 105b and fixed by the tightening knob 105c.

  The switching plate 110 has a rectangular plate shape as described above, and is arranged inside the switching box 101 so as to be movable in parallel along the first wall 102. A connection pipe hole, which is a hole (not shown), is disposed at the center of the switching plate 110, and a tubular connection pipe section 105a of the connection pipe 105 is fixed to the connection pipe hole.

  The collar 106 has a hollow cylindrical collar upper part 107 and a hollow cylindrical collar lower part 108. The collar upper part 107 has a larger diameter than the collar lower part 108, and accommodates a coil spring 109 therein. can do. In addition, between the hollow cylindrical collar upper part 107 and the hollow cylindrical collar lower part 108, there is a step part 107a having a step shape to fill the difference in diameter.

  A tubular connecting tube portion 105a of the connecting tube 105 is disposed inside the lower collar portion. The diameter of the collar lower portion 108 is large enough to allow the tubular connection tube portion 105a of the connection tube 105 to be slidably disposed, and has a slight clearance with respect to the diameter of the tubular connection tube portion 105a of the connection tube 105. have. As described above, although the collar upper portion 107 has a larger diameter than the collar lower portion 108, the collar upper portion 107 can accommodate the coil spring 109 disposed so as to be attached to the connection pipe portion 105a disposed therein. Having a sufficient diameter.

  One end of the coil spring 109 is arranged so as to be in contact with a step portion 107 a having a stepped shape between the upper collar portion 107 and the lower collar portion 108, and the other end is in contact with the switching plate 110. As a result, the switching plate 110 is pressed by the elastic force of the coil spring 109 in a direction in which the switching plate 110 comes into contact with the first wall portion 102. Thereby, the connection pipe portion 105a of the connection pipe 105 and the solid pipe 70 or the liquid pipe 80 connected to the switching section 100 are connected by a user's intention. This will be further described later.

  The connecting pipe 105 is pulled in the direction of the second wall 103 so as to oppose the elastic force of the coil spring 109. As a result, the connection between the connection pipe 105 and the solid pipe 70 or the liquid pipe 80 connected to the switching unit 100 is released. Thereafter, by sliding the switching plate 110 in the left-right direction, the liquid pipe 80 or the solid pipe 70 is connected to the connection pipe portion 105a of the connection pipe 105.

  The cleaner 10 according to the present embodiment can be disposed on a cart 200. The trolley 200 has a loading platform 201, a handle 202, front casters 203 and 203, and rear casters 204 and 204. The loading platform 201 is for mounting the cleaner 10, and the front casters 203 are so-called free casters, which can change the direction. The diameter of the wheels of the front casters 203 is preferably 100 mm. The rear casters 204, 204 are casters fixed in the forward direction, and preferably have a wheel diameter of 150 mm. This is suitable when traveling in a place where the ground is not leveled, and can prevent a fall.

  A method of using the cleaner 10 having the above configuration will be described. A user (not shown) determines whether the target to be suctioned is a solid or a liquid. A case where the suction target is a solid and the liquid pipe 80 and the connection pipe 105 are connected in advance will be described (see FIG. 5).

  A user (not shown) pulls the connection tube 105 in the direction of the second wall 103 so as to oppose the elastic force of the coil spring 109. As a result, the connection between the liquid pipe 80 and the connection pipe portion 105a of the connection pipe 105 is released (see FIG. 7). Further, a user (not shown) moves the connection pipe 105 along the elongated hole 104 in the second wall 103. The length of the major axis in the horizontally elongated hole 104 is the amount of movement of the connection pipe 105, and coincides with the distance between the solid pipe 70 and the liquid pipe 80. Therefore, the connection pipe 105 can be moved from the other end of the long diameter in the long hole 104 to one end (see FIG. 8).

  By moving the connection pipe 105 from the other end of the long diameter in the long hole 104 to one end, the switching plate 110 to which the connection pipe 105 is connected also moves. The switching plate 110 moves close to the other side wall portion 101b of the switching box portion 101 having a horizontally long rectangular parallelepiped shape, and moves to a position where the connection pipe 105 faces the solid pipe 70. Thereafter, the connecting pipe 105 a of the connecting pipe 10 pulled in the direction of the second wall 103 is returned in accordance with the contraction force of the coil spring 109 so as to oppose the elastic force of the coil spring 109, so that the connecting pipe 105 is returned. Is connected to the solid pipe 70. Since the liquid pipe 80 is closed by the switching plate 110, no airflow is sucked from the liquid pipe 80.

  Thereafter, the user turns on a switch (not shown), causes the suction unit 20 to exert a suction force, and sucks solids from the suction hose 160 connected to the connection pipe 105. The solid is sucked and stored by the suction force of the suction unit 20 from the lower cover 22 of the suction unit 20 to the solid storage unit 30 via the connection pipe 105, the switching unit 100, and the solid pipe 70. (See FIG. 9B, arrow X). The airflow is discharged to the outside through the discharge hole 21a in the suction unit 20.

  On the other hand, since the liquid pipe 80 is closed by the switching plate 110, the suction force of the suction unit 20 can be exerted to suck the solid by the solid suction pipe 70 (see FIG. 8).

  Next, a case where the target to be sucked is a liquid and the solid pipe 70 and the connection pipe portion 105a of the connection pipe 105 are connected in advance will be described.

  A user (not shown) pulls the connection tube 105 toward the second wall 103 so as to oppose the elastic force of the coil spring 109. Thereby, the connection between the solid pipe 70 and the connection pipe portion 105a of the connection pipe 105 is released. Further, a user (not shown) moves the connection pipe 105 along the long hole 104 in the second wall 103. The length of the major axis in the horizontally elongated hole 104 is the amount of movement of the connection pipe 105, and coincides with the distance between the solid pipe 70 and the liquid pipe 80. Therefore, the connection pipe 105 can be moved from one end of the long diameter of the long hole 104 to the other end (see FIG. 5).

  By moving the connection pipe 105 from one end of the long diameter in the long hole 104 to the other end, the switching plate 110 to which the connection pipe 105 is connected also moves. The switching plate 110 approaches the side wall portion 101 a of the switching box portion 101 having a horizontally long rectangular parallelepiped shape, and moves to a position where the connection pipe 105 faces the liquid pipe 80. Thereafter, the connecting pipe portion 105 a of the connecting pipe 10 pulled in the direction of the second wall 103 is returned in accordance with the contraction force of the coil spring 109 so as to oppose the elastic force of the coil spring 109, so that the connecting pipe is returned. The connection pipe section 105a in 105 and the liquid pipe 80 are connected. Since the solid pipe 70 is closed by the switching plate 110, no airflow is sucked from the solid pipe 70.

  Thereafter, the user turns on a switch (not shown) and causes the suction unit 20 to exert a suction force. The suction force sucks the liquid from the suction hose 160. Due to the suction force of the suction unit 20, the suctioned liquid is stored in the tank unit 41 of the liquid storage unit 40 from the suction hose 160 via the connection pipe 105, the switching unit 100, and the liquid pipe 80. (See FIGS. 10A and B, arrow Y). Further, the sucked airflow flows from the tank upper part 42 in the liquid storage part 40 to the lower cover 22 in the suction part 20 through the liquid suction pipe 85 (see FIGS. 11A and 11B, arrow Z), and is discharged outside through the discharge hole 21a. You.

  On the other hand, since the solid pipe 70 is closed by the switching plate 110, the suction force of the suction unit 20 can be exerted to suck the liquid by the liquid pipe 80.

  As described above, the float 401 is incorporated inside the tank upper part 42 of the liquid storage part 40, and the stopper 403 connected to the float 401 by the connecting rod 402 rises with the rise of the float 401. And a super stop mechanism 400 for closing an inlet of the liquid suction pipe 85 to stop overflow at the time of liquid suction. Further, the suction air M including the mist in which the liquid is almost completely removed from the sucked liquid (see arrow Y in FIG. 12) but the fine liquid is scattered is formed in a slit shape arranged so as to surround the float pipe 404. When the mist enters the slit 410 having a gap, the mist is collected, and the mist is turned into a liquid, thereby preventing the liquid from entering through the liquid suction pipe 85. Therefore, the suction air (arrow Z) containing almost no mist is sucked into the liquid suction pipe 85. Therefore, the mist can be prevented from entering the suction section 20 through the liquid suction pipe 85 (see FIG. 12).

  In this way, the user stores the liquid in the liquid storage part 40 and fixes the liquid in the solid storage part 30 by previously identifying the target to be suctioned by the user (not shown). Separation may be very easy, which may allow the reuse of liquids or solids. As a result, the resource regeneration rate increases, and waste can be reduced and disposal costs can be recovered. Further, it is possible to reduce the amount of washing water for sludge and sewage, and to reduce the labor and time for the drying operation and the separation operation.
