BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to cleaning tools and, more particularly, to a screen cleaner for cleaning a screen from one side of the screen.

[0002]

2. Description of the Related Art In order to prevent mosquitoes and other pests from entering a room, especially in the summer, to release hot indoor air outside and to bring cool outside air indoors, it is necessary to attach a screen door to a window. Many. Thus, when air inside and outside the room moves through the screen door, mud, dirt, dust, oil, small insects, etc. may adhere to the screen door. Therefore, it is necessary to clean the screen door in order to improve the ventilation.

Hitherto, various types of screen door cleaning devices have been disclosed as follows. JP 11

[0004] These screen door cleaning devices are basically provided with a first cleaning member for wiping one surface of the screen door so that both sides of the screen can be simultaneously cleaned in a state where the screen is installed, and a screen door. And a second cleaning member for wiping the other surface. An S pole of a magnet is provided at the center of the first cleaning member to move the second cleaning member along the other surface of the screen door following the first cleaning member moving along one surface of the screen door. (Or N pole) is located at the center of the second cleaning member, and a magnet or a magnetic body is located at the N pole (or S pole) of the magnet. Are configured to be magnetically attached to each other, and a cleaning portion is formed on these cleaning members. These cleaning portions sandwich both sides of the screen door, and thus clean the screen door from both sides.

[0005]

These cleaning devices are:
It offers an excellent effect in that both sides of the screen can be cleaned at the same time. However, in such a cleaning device, for example, the first
Since the second cleaning device outside the screen door is magnetically attached to the cleaning member and moves, the moving speed of the first cleaning member needs to be moved at a very low speed. Become longer. In addition, the second cleaning device outside the screen door follows the first cleaning device in a linear direction with a slow speed, but it is extremely difficult to follow the rotation direction, so that cleaning around the corner of the screen door is very difficult. Have difficulty. Furthermore, since a large magnet is attached to the center of the cleaning device, the cleaning unit easily runs short of a cleaning liquid such as a soap solution, and it is necessary to draw the cleaning device to hand each time. Overall, the replenishment work is difficult. In addition, in order to wipe off the cleaning liquid adhering to the screen door, it is necessary to sandwich a liquid adsorbing member such as a cleaning liquid wiping cloth between the first and second cleaning devices that are opposed to each other. Since the positions of the apparatuses are separated from each other, it is more difficult to simultaneously move the two, and as a result, it is difficult to wipe the cleaning liquid attached to the screen door. Further, when the first cleaning member on the inner side is unintentionally pulled away from the screen door, for example, in an attempt to replenish the cleaning liquid or by another unexpected operation, the second cleaning member on the outer side of the screen door falls from the screen door. is there.

An object of the present invention is to provide a screen cleaning apparatus which solves these problems.

[0007]

According to the present invention, there is provided a cleaning work unit, a gas-liquid separation unit, a suction unit,
Provided is a connection means for connecting a gas-liquid separation section and a suction section, and a screen cleaning tool for cleaning the screen from one side of the screen. This cleaning tool has a surface on which the cleaning section is opposed to the screen door, and on this surface, a felt for providing a cleaning liquid to the screen door, a brush for cleaning the screen door with the cleaning liquid, sewage after cleaning, screen screen And a suction port of a sewage passage for sucking in foreign substances, ambient air, and the like attached to the sewage together. Further, the sewage passage is connected to a gas-liquid separation unit, and the gas-liquid separation unit has a gas-liquid separation mechanism, and the gas-liquid separation mechanism removes sewage, foreign matter, air, etc. sucked from a suction port. The gas is separated into the gas and the other gas, and the gas other than the gas is stored in the inside, but the separated gas is supplied to the suction unit via the connection means.

[0008]

Embodiments of the present invention will be described below. It will be understood, however, that the embodiments described are merely illustrative of the invention and that the invention is not limited by this illustration, but only by the appended claims.

FIG. 1 is an overall view of a screen cleaning apparatus 1 for cleaning a screen according to the present invention. As shown in FIG. 1, the cleaning device 1 is used to face a screen door 2, and generally includes a cleaning operation unit 3, a gas-liquid separation unit 4,
For example, a suction unit 5 formed of a known vacuum cleaner or the like, and a connection unit 6 configured to connect the gas-liquid separation unit 4 and the suction unit 5 with a hose of a similarly known vacuum cleaner are configured. . Here, the cleaning operation unit 3 or the gas-liquid separation unit 4 is a part that the operator manually wipes the screen surface during cleaning operation. Preferably, the cleaning section 3 and the gas-liquid separation section 4 are separately formed, and both are assembled by welding or bonding later. The cleaning section 3 is constituted by a cleaning body 10. A brush 12 for directly cleaning the screen 2 is provided on a surface of the cleaning body 10 facing the screen 2,
A felt 14 for applying a cleaning liquid to the screen 2 prior to cleaning, and a sewage passage 16 for sucking sewage after cleaning from the screen 2 are provided.

FIG. 2 is a view of the cleaning main body 10 as viewed from above. The distal end of the cleaning unit 3 is spread laterally so as to form a substantially T-shape, thereby facilitating the wiping operation.

FIG. 3 is a view showing a surface of the cleaning work unit 3 facing the screen door. A brush 12 is mounted on an upper portion, and a felt 14 is mounted on a lower portion. A sewage passage 16 for sucking a dirty cleaning liquid after screen door cleaning is disposed in an intermediate portion.

Hereinafter, the screen door cleaning device of the present invention will be described in more detail. FIG. 4 is a cross-sectional view showing a state where the screen of the built-in screen door 2 is wiped by the screen door cleaning device 1 according to the present invention.

The cleaning section 3 has a function of directly wiping the screen door 2, and is formed by a cleaning body 10 having a slightly bent distal end so as to facilitate the wiping operation. The front part of the cleaning main body 10 (see FIG. 3) corresponding to the left side surface of the cleaning main body 10 shown in FIG.
The brush 12 is mounted on the upper part. The end of the brush 12 comes into direct contact with the screen 2 to wipe and clean the screen 2. Further, a felt 14 for applying a cleaning liquid to the screen door 2 is attached to a lower portion. Further, a sewage passage 16 is formed at an intermediate portion and at a position close to the brush 12 for supplying water from the felt 14 and sucking sewage after the screen door 2 is wiped by the brush 12. By arranging the sewage passage 16 at a position close to the brush, the sewage adhered to the brush can be easily sucked, that is, collected, and the spillage of sewage to the vicinity can be minimized.

Here, the brush 12 constitutes a brush unit 20 whose base end is planted on a resin-made cylindrical body 18 at intervals of about 3-5 mm every 5-10 brushes. The brush unit 20 has a semi-cylindrical groove 22 (see FIG. 5) formed above the surface of the cleaning body 10 (see FIG. 3).
Inserted into. The groove 22 communicates with a slot 24 on the surface of the cleaning main body 10. The slot 24 receives the brush 12 and extends the tip of the brush 12 to the screen 2, and at the same time, the brush unit 20 The brush 22 is capable of swinging up and down in the groove 22 and provides an action of restricting the amount of vertical movement of the end of the brush 12 (see FIG. 6). When mounting the brush unit 20 in the groove 22, first, the cylindrical body 18 of the brush unit 20 is aligned with the open end of the groove 22, and
The second part is aligned with the groove 22, and then the brush unit 20 is slowly transferred to the closed end along the longitudinal direction of the groove 22 and the slot 24 (the left-right direction in FIG. 2). In this way, the brush unit 20 can be mounted very easily to the position shown in FIG. After mounting, if an elastic filler is arranged at the open end, it can be prevented from coming off. Of course groove 2
The two ends may be open ends so that they can be mounted from either the left or right side of the groove. In this case, after mounting, both ends of the groove can be closed with filler.

As a result of the applicant's experiment, the brush 12 is preferably a synthetic resin brush when the screen door 2 is made of resin, and a pig bristle brush when the screen door 2 is made of stainless steel. It is known. Thereby, the screen door can be prevented from being deformed or broken. When a hard and short brush is used, the degree of dirt removal, that is, the cleaning effect is enhanced, but breakage of the screen is accelerated. On the other hand, a soft and long brush prevents breakage of the screen (especially a resin screen), but the cleaning effect is reduced. It has been found at the same time to fall. According to the experiment by the inventor, the length of the brush is generally about 5 from the relationship between the moving speed of the normal brush, that is, the cleaning speed, and the pressing force of the screen door during cleaning.
It has been found that a preferable result is about -20 mm.

The felt 14 is made of a material having an appropriate water conductivity, strong against contact friction with a screen door, and at the same time strong against bending and stretching during cleaning. For example, GS felt of Toray Industries, Inc. can be used advantageously. The felt 14 is bent at the tip of the felt at the time of wiping, and supplies the cleaning liquid to the screen door.

As shown in FIG. 4, the sewage passage 16 is provided with a suction port 16a opened at the front of the cleaning body 10.
A discharge port 16b connected to the gas-liquid separation unit 4,
And a connection passage 16c connecting the two. Preferably, the suction opening 16a is arranged perpendicular to the plane of the screen door 2, and the passage 16c
Extend therefrom in a substantially vertical direction and then bend generally along the shape of the body 10. Here, suction opening 1
The height h (see FIG. 3) of 6a is preferably about 3-8 mm. When this value is small, the suction force increases and the suction amount of sewage increases, but the suction of dirt components such as mud, oil, and relatively large lumps such as garbage and carcasses of insects is prevented.
If it is too large, the suction power of the sewage is deteriorated, and satisfactory suction of the sewage cannot be performed. As a result of measuring dimensions of mud, oil, dust, and the like, which are general contaminants adhering to the screen door, those dimensions were about 0.03 mm at the maximum. For this reason, more preferably, the suction opening 16 is provided.
The height dimension of a is 3-5 mm.

The felt 14 is attached in a liquid-tight state to a longitudinal side wall portion of a detachable cylindrical body 30 disposed below the front portion of the cleaning main body 10. As shown in FIG. 7, the cylindrical body 30 has a hollow portion, that is, a tank 32 for accommodating the cleaning liquid therein.
According to the illustrated example, the hollow portion 32 penetrates the entire length of the cylindrical body 30, and both ends of the hollow portion 30 are sealed with plugs 34.
Although sealed by a broken line in FIGS. 3 and 4, the tank 32 can be provided with a blind plug 34 as a blind hole with a bottom only in one opening. Furthermore, the cylinder 3
0 is a radially outwardly extending cavity 36 for attaching the inner end of the felt 14 in a liquid-tight manner.
Is formed, and the space 36 is preferably formed in the cylindrical body 30.
Extend along the entire length in the longitudinal direction of. The inner end of the cavity 36 communicates with the hollow portion 32 through a narrow inner slit 38. On the other hand, the outer end of the space 36 communicates with the outside of the cylindrical body 30 via the outer slit 40. The interval between the outer slits 40 is approximately similar to the thickness dimension when the felt 14 is compressed in the thickness direction.

As shown in FIG. 7, the cylinder 30 further includes
To accommodate the lock key 46 having an oval or wedge-shaped cross section, a lock groove 48 having a cross section slightly smaller than the shape of the lock key 46 is formed near the lower portion of the cavity 36. . The lock groove 48 is expanded by forcibly inserting the lock key 46 therein.
For this reason, the interval between the outer slits 40 adjacent thereto is narrowed, and the felt 14 is firmly held in the cylindrical body 30.

When the felt 14 is mounted on the cylinder 30, the lock key 46 is removed from the lock groove 48. In this state, the felt 14 is inserted into the space 36 and the outer slit 40 while the base end of the felt 14 is arranged in the space 36 and the intermediate portion of the felt 14 is arranged in the outer slit 40.
At this time, the distal end of the felt 14 is
It extends linearly outward of. After the felt 14 is completely installed in the space 36 and the outer slit 40, the lock key 46 is inserted into the lock groove 48. Thereby, the outer slit 40 is narrowed. For this reason, felt 14
And the flow of the cleaning liquid flowing through the felt 14 is reduced by 1 cc-per one wiping operation.
It is regulated to limit to about 2cc. This is because it has been found that when the supply amount of the cleaning liquid is larger than this, a dropping phenomenon of the cleaning liquid occurs, and when the supply amount is too small, appropriate cleaning is not performed. In addition, a recess 50 having a preferably circular component shape for providing a latch function described later is formed in a lower portion of the cylindrical body 30.

The cylindrical body 30 on which the felt 14 is mounted
Is a cylindrical housing 52 formed at the lower front part of the main body 10.
It is detachably attached to For this reason, a latch portion 54 that is bent upward is formed integrally with the main body 10 at a position below the front surface of the main body 10 and below the cylindrical housing portion 52. The latch 54 has a preferably circular component shape at its upper end. Then, the cylindrical body 30
When the cylinder 3 is mounted on the cylinder housing 52, first, the cylinder 3
The 0 dent 50 is engaged with the latch portion 54. Next, the cylinder 30 is rotated clockwise in FIG. Thereby, the cylindrical body 30 is easily fitted into the cylindrical body accommodating portion 52. In this state, since the cylindrical housing portion 52 has a somewhat elastically expanded state and the latch portion 54 holds the cylindrical body 30, the cylindrical body 30 may fall from the cylindrical housing portion 52. Has been prevented. When detaching the cylindrical body 30 from the main body 10, the cylinder body 30 can be easily detached by performing an operation opposite to that at the time of mounting.

The gas-liquid separator 4 receiving the main body 10 at one end (upper end) has a substantially cylindrical shape having a size such that the cleaning worker can easily hold the main body 10 by hand. It is constituted by a body 60. In addition, this holder 6
Numeral 0 elastically holds the connecting means holding member 62 to which the end of the connecting means 6 is fixed at the other end (lower end). The holding body 60 has an introduction pipe 64 extending upward and downward from near the center in the radial direction. The introduction pipe 64 has a receiving end 64a that receives the discharge port 16b of the sewage passage 16 and a discharge end 64b that extends almost to the middle of the holder 60 and discharges a mixed fluid of sewage and air there. And The introduction pipe 64 is the sewage passage 1
6 has a function of conveying the mixed fluid of the sewage sucked from the suction port 16 a and the air around the sewage to the gas-liquid separation unit 4.

A gas-liquid separation mechanism 66 is provided at an intermediate portion of the holder 60.
Are formed. The gas-liquid separation mechanism 66 has a reduced diameter passage 68 at an intermediate portion.
As shown in the figure, the upper gas-liquid receiving space 66A and the lower liquid receiving space 66B communicate with each other. Further, in FIG. 4, an inner passage 70 is formed above the gas-liquid receiving space 66A, around the discharge end 64b, and extending upward therefrom. The upper end of the inner passage 70 is closed by an upper end wall 72. An outer passage 74 is formed around the inner passage 70. The inner passage 70 and the outer passage 74 communicate with each other by a radial passage 76 extending radially near the upper end wall 72.

Further, the outer passage 74 is a narrow and long cylindrical passage formed between the cylindrical outer peripheral wall 78 of the holder 60 and the cylindrical inner peripheral wall 80 defining the gas-liquid receiving space 66A. Via 82, it is connected to a connecting means holding member 62 elastically held at the lower end of the holding body 60. The cylindrical inner peripheral wall 80 extends to a position below the holder 60 and is closed by a bottom portion 80a.
An opening 80b is formed in the bottom 80a.
Ob is closed by a rubber stopper 80c, for example.

From the intermediate portion of the cylindrical inner peripheral wall 80, first, a conical inward slope wall 80e extending radially inward and obliquely downward, and held from the lower end of the inward slope wall 80e. A cylindrical reduced-diameter wall 80f extending along the longitudinal axis of the body 60 and forming the reduced-diameter passage 68, and extends obliquely outward and downward in the radial direction from the lower end of the reduced-diameter wall 80f. 80g of a conical outwardly inclined wall, and a cylindrical enlarged wall extending from the lower end of the outwardly inclined wall 80g along the longitudinal axis of the holder 60 and defining a liquid receiving space 66B therein. 80d, and a hanging cylindrical body 80d having a bottom wall 80i closing a lower end of the enlarged diameter wall 80h.
Is drooping. An opening 80j is formed in the bottom wall 80i. Further, preferably a single metal ball 84 is accommodated in the liquid receiving space 66B between the reduced diameter wall 80f and the bottom wall 80i. The size of the ball 84 is larger than the diameter of the reduced diameter passage 68 defined by the reduced diameter wall 80f and the opening 80 defined in the bottom wall 80i.
greater than j. This prevents the ball 84 from falling out of the liquid receiving space 66B. The raised portion 80k provided around the opening 80j of the bottom wall 80i is an adhesion preventing means for preventing the ball 84 from adhering to the bottom wall.

As is apparent from FIG. 4, the bottom 80a of the cylindrical inner peripheral wall 80 and the bottom wall 80i of the hanging cylindrical body 80d.
And a gap 86 is formed between the inner wall and the inner wall of the cylindrical inner peripheral wall 80, and the gap 86 extends between the outer surface of the hanging cylindrical body 80d.

Hereinafter, a method of using the screen cleaning apparatus 1 of the present invention will be described with reference to FIG. Prior to use, first (if necessary, remove the cleaning body 10 from the cylindrical body 30).
), Remove the hermetic plug 34 (one if there are two) from the cylindrical body 30 and inject a predetermined amount of a predetermined cleaning solution into the hollow portion 32. Thereafter, the hollow portion 32 is sealed so that the cleaning solution does not leak outside. When the cylinder 30 is removed from the cleaning main body 10 by closing the sealing plug 34 to the cleaning main body 32,
Attach to 0. The cleaning liquid injected into the hollow portion 32
It flows into the space 36 through the inner slit 38 (see FIG. 7). There, the cleaning liquid is sucked into the base of the felt 14 housed in the space 36. The cleaning liquid sucked into the base of the felt 14 flows to the tip of the felt 14 via the felt 14 housed in the outer slit 40. However, since the flow rate of the cleaning liquid is restricted by the outer slit 40, the cleaning liquid
It does not flow out from the tip of the jar.

Next, a switch (not shown) is turned on,
The suction unit 5 is set to the operating state. When the suction unit 5 is operated, the fluid in the vicinity of the screen door 2 causes the suction port 16a, the passage 16c, the discharge port 16b, the discharge end 64b, the gas-liquid receiving space 66A, the inner passage 70, and the radial direction of the cleaning work unit 3 to move. It is confirmed through the passage 76, the outer passage 74, the passage 82, the connecting means holding member 62, and the connecting means 6 that suction to the suction portion is started as shown by arrows 90-99. If such fluid movement is not performed, clogging has occurred in any part of the passage, and the clogged portion is previously filled with high-pressure fluid such as pressurized water or compressed air (suction port 16a or It has to be cleaned and removed by flowing) to the connection means 6). After the above-described fluid flow is confirmed, the screen door wiping operation is started.

In the wiping operation, an operator grasps the device 1 and stands in front of the screen door 2 to move the brush 12 and the felt 14.
And lightly contact the screen door 2 at the same time, and then slowly move the device 1 vertically along the surface of the screen door 2. Apparatus 1
Contacting the screen door 2 too strongly may cause the screen door 2 to be damaged. On the other hand, if the contact pressure is weak, desired cleaning cannot be performed. For this reason, it is desirable that the device 1 be lightly touched to the screen door 2 and be moved up and down several times. Felt 1 to screen door 2
8, the tip of the felt 14 is bent at a position outside the outer slit 40 as shown in FIG. 8, so that the cleaning liquid held by the felt 14 is pushed out of the felt and the surface of the screen door 2 Adhere to By moving the apparatus 1 up and down, the brush 12 cleans the screen 2 while the cleaning liquid attached to the screen 2 is dispersed along the surface of the screen 2. Thus brush 12
During the cleaning of the screen 2, since the suction unit 5 is operating, the cleaning liquid contaminated by the brush 12 cleaning the screen 2 removes the contaminants separated from the surface of the screen 2 and the surrounding air. And, along with the scattered water of the cleaning liquid supplied from the felt 14, the water is quickly sucked into the suction port 16a of the sewage passage 16 as shown by arrows 90 and 91.

The contaminated cleaning solution sucked into the suction port 16a of the sewage passage 16, the contaminant foreign matter separated from the screen door, the surrounding air, and the surrounding air are indicated by arrows 90, 91, 92,
As shown by 93, the gas flows into the sewage / air receiving / introducing pipe 64 through the passage 16c and the discharge port 16b, and then flows into the gas-liquid receiving space 66A of the gas-liquid separation mechanism 66 from the discharge end 64b. In the air space 66A, the liquid and the fixed component are separated by gravity. For this reason, heavy objects such as the contaminated cleaning liquid and contaminant
As shown by, the liquid flows down the reduced-diameter passage 68 and is accumulated in the liquid receiving space 66B.

On the other hand, the air that flows into the gas-liquid receiving space 66A and flows into the liquid receiving space 66B together with the surrounding air separated from the liquid and the fixed component and the contaminated liquid, etc. 95, 96, 97, 9
As shown at 8, 99, the inner passage 70, the radial passage 7
6, through the outer passage 74 and the passage 82, into the connecting means holding member 62, and then, as shown by the arrow 100, through the connecting means 6 to the suction section 5, where it is discharged out of the system.

In the present invention, the lower end of the inner passage 70 is positioned farther from the reduced diameter passage 68 than the lower end of the discharge end 64b so that contaminated liquid or the like does not flow into the suction section 5. Contaminated liquid, etc., in the liquid receiving air space 66
The lower surface of the gas-liquid separation mechanism 66 is formed by an inward inclined wall 80e so that the gas-liquid separation mechanism 66 can be easily accumulated in the inside B. Further, the discharge end 64b of the sewage / air receiving / introducing pipe 64 for introducing a contaminated liquid or the like into the gas / liquid receiving air space 66A is connected to the inwardly inclined wall 8.
The end is obliquely inclined so as to face 0e. Further, even if the mist of moisture is sucked into the inner passage 70 together with the air, the passage 82 is narrow, and when passing through it, the mist contacts the wall surface of the passage and solidifies to form droplets. Accumulate inside. For this reason, there is almost no liquid component in the fluid sucked into the suction unit 5.

The contaminated cleaning liquid or the like once stored in the liquid receiving space 66B does not flow out of the apparatus 1 even if the apparatus 1 is thereafter turned upside down. This is because, when the apparatus 1 is in an inverted state, the ball 84 housed in the liquid receiving space 66B functions as a check valve for closing the reduced diameter passage 68. Also, the liquid receiving air space 66
The contaminated cleaning liquid and the like accommodated in B are accommodated in the gap 86 from the opening 80j provided in the bottom wall 80i that forms the bottom of the space 66B, and when the apparatus 1 is in an inverted state, the contaminated cleaning liquid and the like are removed. This is because the liquid flows into the liquid receiving air space 66B, the reduced-diameter passage 68, and the air region 86A radially outward of the gas-liquid receiving air region 66A, and does not return to the liquid receiving air region 66B again. The contaminated cleaning liquid and the like contained in the air spaces 86 and 86A can be easily discharged from the air space by separating the holding member 62 from the holding body 60 and further removing the stopper 80c. Further, by forming the holding member 62 from a transparent or translucent resin, the amount of water accumulated in the holding member 62 can be easily recognized, and thus, the water can be easily discharged therefrom. I can do it.

In the above embodiment, the brush 12 is mounted on the cylindrical body 18. In this case, however, the cylindrical body 1
8 to the cleaning body 10 and the cylindrical body 3 to the cleaning body.
0 can be mounted by the same means as the mounting method. Further, the brush 12 can be directly mounted on the cleaning main body 10.

Further, as an improvement of the present invention, the brush 12 can be disposed in the sewage passage 16. Accordingly, when the brush contacts the upper (or lower) sewage passage during the cleaning operation, the upper (or lower) sewage passage is narrowed, and the suction port area is correspondingly narrowed. As a result, the suction force is increased, and thus the suction force is increased. Sewage adhering to the screen door is on the lower side (or upper side)
This is because the wastewater can be more effectively recovered from the wastewater passage.

Further, in the illustrated example, the felt is disposed below the brush. However, the present invention is not limited to this. The felt may be disposed at the illustrated brush position and the felt may be disposed at the felt position. It is possible.

9 to 11 disclose another embodiment of the present invention. This embodiment is different from the above-described embodiment in that a roller 112 is mounted on the cleaning body 110. For those who are unfamiliar with screen door cleaning, it may be difficult to clean while maintaining the distance between the screen door and the cleaning body at a preferable position of about 3 mm. For this reason, in this embodiment, in order to assist the worker so that the cleaning main body always keeps the optimal cleaning position of about 3 mm from the screen door, a diameter dimension is set such that the cleaning main body is separated from the screen surface by a predetermined distance. Is installed. In the example shown, the roller 11 is placed against a stopper 134 closing the hollow part 32 holding the cleaning liquid.
2 is installed. For this reason, the sealing plug 134 is
As shown in FIG.
14 and a sealing wall 116 having an enlarged diameter and sealing the hollow portion 32, and a rotating shaft 120 extending outward from the sealing wall 116. A roller 112 is mounted on the rotating shaft 120. This roller 1
12, the cleaning body 110 is about 3 mm from the screen door 2.
It is dimensioned so as to be held at a position separated only by. In addition, a groove 1 for receiving an O-ring or the like so that the roller 112 does not come off is formed in an outer end portion of the rotating shaft 120.
22 are formed. Here, the roller 112 is preferably formed of resin. Further, in order to reduce the weight, the roller 112 may have a hollow shape.

The mounting position of the roller 112 is not limited to the hermetic plug 134, but can be appropriately provided at an appropriate position on the side surface of the cleaning main body 110.

The cleaning tool of the present invention does not clean both sides of the screen simultaneously, unlike the conventional screen cleaning apparatus, but the cleaning liquid attached to the screen by the felt spills to the opposite side of the screen by the brush action. Then, after flowing on the opposite side of the screen door and moving around the same, the air was sucked together with the surrounding air, so that it was found that the opposite side of the screen door and the mesh portion of the screen could be sufficiently washed. As a result of an experiment of simultaneously cleaning ten screen doors built by the applicant using the present apparatus and a known apparatus, the time required to achieve substantially the same cleaning effect is shorter in the present apparatus than in the known apparatus. It has been found that about one-third of the time required for the apparatus is sufficient. This is because it is very easy to add the cleaning liquid in the present apparatus, and in the known apparatus, the cleaning apparatus outside the screen door must be drawn to the hand every time the cleaning liquid is added, and The start and end procedure is extremely complicated. In addition, according to the known device, it has been found that the device always holds the screen door from both sides during cleaning, and that the screen door is severely damaged. On the other hand, according to the present device, the contact pressure between the screen door and the brush can be freely adjusted, so that the screen door is less damaged. For this reason, the tool can be easily cleaned even if the screen is slightly damaged.However, in the known apparatus, in the case of the screen which is about to be damaged, the apparatus cuts into the screen at the place and damages the screen. It turned out to spread. Furthermore, although it is very difficult and sometimes not possible at all to clean the corners of the screen door with the known devices, there are no such defects in the present device. With a known apparatus, it is very difficult to replenish the cleaning liquid and it is almost impossible to wipe off the cleaning liquid attached to the screen door. Although there is flexibility, this problem has been completely solved by the present device. Moreover, there is no danger of dropping the cleaning implement outside the screen door. Furthermore, since the cleaning body can be held at the optimum position from the screen with the help of the roller, even a beginner can always easily perform the optimum screen cleaning operation.
