Description

Built-in cleaner for cleaning room by negative pressure and positive pressure by negative pressure and positive pressure.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a built-in vacuum cleaner for cleaning a room by a negative pressure and a positive pressure, and more particularly to a built-in vacuum cleaner for collecting dust, To a main cleaner disposed outside the building.

In a conventional mobile vacuum cleaner, as disclosed in Korean Patent Laid-Open Publication No. 10-2012-0114132, a blower chamber in which a blower is incorporated is disposed downstream of the main body, and a dust collecting chamber for collecting and collecting solid matter such as dust And a suction port connected to the connection pipe provided at one end of the hose is provided at the upstream end of the main body. And the other end of the hose is provided with a distal end pipe having a grip portion at the time of cleaning. One end of the extension pipe is connected to the distal end pipe by a removable material, and the other end of the extension pipe is connected to a suction pipe Suction dart sockets are provided as removable materials.

In the conventional vacuum cleaner having such a structure, when the filter is used for a predetermined period of time, the filter disposed between the blower chamber and the dust collecting chamber is adhered with the solid material, so that the vacuum is not properly formed in the dust collecting chamber. In this case, the user manually flushes the solids attached to the filter to reload or replace the filter.

Such a filter cleaning operation or a filter replacement operation causes the user to touch the object with the hand, thereby causing a problem that it is treated as a very inconvenient and troublesome operation.

In order to solve such a problem, a solid material attached to the filter is shaken into the dust collecting room by vibrating or hitting the filter by the driving source of the blower, or the filtered air flow selectively flowing back into the blower room is selectively backwashed, There is a suggestion to shake it off.

However, such a method still requires a manual operation of discharging the solid material from the dust collecting chamber when a certain amount of solid matter is accumulated in the dust collecting chamber, thereby allowing the user to touch the dislike of the dust such as dust, It is still being treated as a very uncomfortable and cumbersome task.

In order to solve such a problem, a suction chamber provided inside the cleaner main body is excluded, only a suction chamber is provided in the main body, a fan provided in the suction chamber is operated to suck solids outside the main body into the suction chamber without filtration, It is possible to cause the problem that the solid matter causing the contamination sticks to the blade of the fan and it is difficult to form the negative pressure by the fan.

A built-in vacuum cleaner for solving such a problem is disclosed in Korean Patent Laid-Open No. 10-2003-0039876.

The built-in vacuum cleaner includes: a household-specific vacuum cleaner installed in an individual household for collecting and storing cleaning waste temporarily and incorporating a dust-collecting motor;

A suction pipe that is piped from the vacuum cleaner to each individual household unit cleaning area, an inlet formed at the end of the suction pipe, and a cleaning bag coupled to the suction port 30 for cleaning;

A large-capacity central vacuum cleaner connected to the vacuum cleaner and the vacuum cleaner for collecting and collecting the waste collected by each household vacuum cleaner;

A vacuum pump for providing a vacuum to the central vacuum cleaner;

And an opening / closing valve installed in the transfer pipe 50 for each household to control the transfer of waste from the generation-specific vacuum dust collector to the central vacuum dust collector.

The built-in vacuum cleaner described above operates the dust collecting motor of the new vacuum cleaner to temporarily collect the garbage generated in the individual generation into the vacuum cleaner for each generation by the negative pressure, and temporarily collects the collected garbage in the vacuum cleaner The vacuum pump of the central vacuum dust collector is operated to collect the trash temporarily collected in each of the household vacuum cleaners.

However, the built-in vacuum cleaner described above collects garbage from a vacuum cleaner to a central vacuum cleaner by a sound pressure source, so that all households simultaneously discharge garbage from a household vacuum cleaner to a central vacuum cleaner, There is a problem that the operation cost and installation cost are increased because a large-capacity vacuum pump is operated when the generation of the garbage is discarded from the one generation to the central vacuum dust collector or when the garbage is simultaneously discarded in the central vacuum dust collector from several generations.

Further, when the built-in vacuum cleaner is applied to a private house, the central vacuum cleaner is arranged in an alleyway outside the house in order to provide easy garbage collection to the garbage collecting company, and there is a high possibility that the expensive vacuum pump is stolen .

In addition, the built-in vacuum cleaner includes a dust-collecting motor for collecting garbage for each household by a household vacuum cleaner and a vacuum pump for collecting the garbage temporarily collected in the household vacuum cleaner to a central vacuum cleaner, There is a problem that the operation cost and the installation cost are increased.

The present invention has a problem in solving the above-mentioned problems.

The present invention is characterized in that a cleaner main body is provided as a built-in indoor or outdoor building, and a dust collecting chamber, a suction chamber and a discharge chamber formed by partition walls are provided in the main body, the discharge chamber being disposed under the dust collecting chamber, A filter is provided in a flow port for communicating the truth and the suction chamber with each other. An air blower is provided in the suction chamber. A flow port for circulating the lower portion of the dust collecting chamber and the discharge chamber is kept airtight The other end of the discharge pipe connected at one end to the discharge port of the suction chamber is connected to the discharge chamber and the other end of the solid discharge pipe connected at one end to the collecting portion disposed outside the building is connected to the discharge chamber The above problems can be solved.

According to the present invention, the vacuum cleaner can be accommodated in the collecting part disposed outside the building by using the negative pressure and the positive pressure by one drive source, It is possible to provide a cleaner to the consumer that allows the user to clean the room at the operating cost while excluding the user from touching the object with the hand.

1 to 3, the built-in vacuum cleaner 100 includes a main body 10 installed to a veranda of a house or outdoor by each household, a suction port (not shown) provided at an upstream end of the main body 10, A suction pipe 1-1 having one end connected to the suction port 1 and the other end connected to a cleaning unit in a household through a wall W so as to be socket- A hose 2 connected to a tip pipe 4 having one end thereof detachably mounted on the suction port 1 in a male socket and the other end having a gripping portion and a hose 2 connected to the end pipe 4 with a detachable material And an extension pipe (5) detachably contacted to the suction duct opening (6).

3, a dust collecting chamber 12, a suction chamber 13, and a discharge chamber 30, which are partitioned by a partition wall portion 11, are provided in the main body 10, and the discharge chamber 30, Is disposed under the dust collecting chamber (12).

The suction chamber (13) is provided with a blower (20).

The flow path 15 for circulating the lower part of the dust collecting chamber 12 and the discharge chamber 30 to each other is provided with a cyclone-like part inside the dust collecting chamber 12, for example, Closing means 40 for maintaining airtightness is provided between the inlet and outlet ports and the discharge port 13a of the suction chamber 13 is connected to the discharge chamber 30. [

Although the inner shape of the dust collecting chamber 12 is described as a cyclone shape in the present embodiment, the present invention is not limited thereto, and the inner shape of the dust collecting chamber 12 may be a hopper shape, And the bottom surface of the hopper shape, the elongated cylindrical shape in the horizontal direction, or the shape of the surface body may have the same area as the opening of the opening / closing means 40. However, in this case, the size of the opening / closing means 40 becomes large. A filter 50 is disposed in the flow port 14 for allowing the dust collecting chamber 12 and the suction chamber 13 to communicate with each other.

The discharge chamber 30 is provided with a discharge port 32 for discharging solids contained in the discharge chamber 30 to the outside of the main body 10, And the other end of the solid matter discharge pipe 71, to which one end is connected, is connected to the collecting part 70 disposed outside the building.

A vent hole 73 through which a filter 72 is inserted in the ceiling portion for discharging the air introduced together with the solids through the solids discharge pipe 71 from the collecting portion 70 to the outside is formed in the collecting portion 70 And a discharge port 75 with a rotary valve 74 interposed therebetween is provided for discharging the collected solid matter.

Water may be filled in the collecting part 70 at a predetermined level and air introduced together with the solids through the solids discharge pipe 71 may be soaked in the water so that dust or the like contained in the solids may be collected in the collecting part 70, and at this time, the filter 72 may be omitted from the vent hole 73. In this case,

When the opening / closing means 40 is a rotary valve, the first gear 42 is fixedly connected to the output shaft 41. The second gear 22 is fixedly connected to the output shaft 21 of the blower 20 And a gear group 43 for deceleration is interposed between the first and second gears 42 and 22 so that the opening and closing means 40 is operated when the blower 20 is engaged with these gears.

4, the opening / closing means 40 may be driven by a separate driving motor without interlocking with the power source of the blower 20. At this time, the user can selectively operate the opening / closing means 40, so that the solid material is temporarily collected in the dust collecting chamber 12 by the negative pressure source without normally operating the opening / closing means 40 When the temporarily collected solid matter is accumulated in the dust collecting chamber 12, the opening and closing means 40 may be operated to collect the solid matter into the collecting portion 70 by the positive pressure source.

The opening / closing means (40) can be a rotary valve which can hermetically block the space between the inlet side and the outlet side and transfer the solids on the inlet side to the outlet side.

 2, the suction port 1 is disposed on one side of the upper end of the dust collecting chamber 12, and the flow port 14 is connected to the dust collecting chamber (not shown) The solids flowing through the suction port 1 drop into the opening and closing means 40 by self weight and centrifugal force in the dust collecting chamber 12 and the load of the filter 50 In this case, the filter 50 interposed in the flow passage 14 may be omitted.

In the above embodiment, when a cutting means (not shown) is provided at the inlet side of the rotary valve as the opening and closing means 40, a long solid matter such as a hair is transferred from the sifted gas collecting chamber 12 to the inlet side of the opening / It is preferable from the viewpoint that a long solid material such as the hair can be cut off and can be easily transferred to the outlet side of the opening / closing means 40 and discharged to the discharge chamber 30.

The built-in vacuum cleaner 100 constructed as described above can be operated as follows.

When the blower 20 is operated, the opening and closing means 40 repeatedly opens and closes, the suction chamber 13 is in a negative pressure state, and the air outside the suction duct opening 6 and the solid (for example, And then flows into the extension pipe 5 via the suction duct opening 6 and then flows into the dust collection chamber 12 by the negative pressure via the end pipe 4, the hose 2 and the suction port 1 , The solids flowing into the dust collecting chamber 12 can not pass through the filter 50 and accumulate toward the opening and closing means 40 in the dust collecting chamber 12 or when the inside of the dust collecting chamber 12 has a cyclone- And the air that has passed through the filter 50 or the flow port 14 is accumulated in the suction chamber 13 and the discharge tube 31 The discharge chamber 30 is opened by the operation of the opening and closing means 40. At this time, The solids introduced into the discharge chamber 30 are accommodated in the collecting section 70 via the discharge port 32 and the solids discharge pipe 71 by positive pressure together with the air discharged to the discharge chamber 30, 70 are discharged to the outside through the filter 72. [

Therefore, the built-in vacuum cleaner 100 of the above-described embodiment allows the vacuum cleaner to be accommodated in the collecting part disposed outside the building by using the negative pressure and the positive pressure by one driving source, It is possible to provide a function of cleaning the interior of the room at the expense of the user, and at the same time, to prevent the user from touching the object with the hand.

In addition, when the built-in vacuum cleaner is applied to an assembly housing, as shown in FIG. 2, the open / close operation is performed at the upstream end of the solids discharge pipes 71 connected to each body 10 provided for each household of the housing house When these solids discharge pipes 71 are connected to one collecting part 70 with the valve 77 interposed therebetween, it is possible to control the number of generations, regardless of whether or not the generations of users are using the built- The solid waste generated in the household is temporarily collected by a sound pressure source provided for each household in the main body 10 provided for each household through the built-in vacuum cleaner 100 provided for each household, and then collected by a positive pressure source provided for each household at the same time, A conventional built-in vacuum cleaner which always uses only a sound pressure source and always needs to operate a large-capacity centralized sound pressure source device Lee, a cleaning of the interior of the apartment at a lower installation and operating costs than conventional possibly can.

The explanation has been made on the case where the dust collecting chamber 12, the suction chamber 13, and the discharge chamber 30 are partitioned by the partition wall portion 11 in the main body 10, but the present invention is not limited thereto The suction chamber 13 and the suction chamber 13 are partitioned in the main body 10 by the partition wall portion 11 in the state where the discharge chamber 30 is excluded and the suction chamber 13 is partitioned into the discharge port 13a of the suction chamber 13 It is also possible to connect the upstream end of the solenoid discharge pipe 71 and bring the discharge side of the opening / closing means 40 into contact with the solids discharge pipe 71. At this time, the opening / closing valve 77 should be disposed at a portion immediately adjacent to the downstream end from the portion of the solids discharge pipe 71 connected to the discharge side of the opening / closing means 40.

Although the solenoid discharge pipe 71 is described as being connected to the collecting portion 70 in the above embodiment, the present invention is not limited to this, and in a state in which the collecting portion 70 is excluded, 71 may be connected to the sewer in the room or outdoor sewerage. In this case, when the solid matter discharged through the solenoid discharge pipe 71 is dust or the like, it is immediately discharged to the sewage treatment plant together with the household wastewater through the sewer, , It is preferable from the viewpoint of eliminating the operation of pulling out the solid matter collected in the collecting part 70.

Here, a water supply pipe (not shown) having an open / close valve (not shown), which is opened when the opening / closing means 40 is operated, is also connected to the sewage part to which the solenoid discharge pipe 71 is connected, ) May be transferred from the upstream end to the downstream end of the sewer together with the water supplied from the water supply pipe. At this time, if a nozzle portion having a porous nozzle hole is provided at the downstream end of the water supply pipe, solid matter ejected from the solids discharge pipe (71) is preferable from the viewpoint that it can be easily sucked into the water supply to be sprayed.

In the above embodiment, the hose 2, the end pipe 4, and the extension pipe 5 are connected to the suction pipe 1-1 connected to the suction port 1 provided at the upstream end of the main body 10, However, the present invention is not limited to this, and the suction duct opening 6 may be connected to a flexible hose (not shown) in a state where the suction duct opening 6 is in a running robotized state as the body of the known robot cleaner 2 to be detachably connected to the suction pipe 1-1.

Accordingly, the expandable hose 2 may be accommodated in the suction duct opening 6 so that the expandable hose 2 may protrude and retract with a different length in the suction duct opening 6.
