Description

[Detailed description of the invention] [Industrial application field] The present invention is a blind cleaning method that automatically cleans so-called Venetian blinds, etc., which have a large number of horizontally extending blades arranged vertically and spaced apart. It is related to the device.

[Conventional technology and problems]

Generally, so-called Venetian blinds are widely used, which are constructed by stacking a large number of horizontally extending blades vertically at intervals. Such blinds tend to have dust, cigarette tar, etc. attached to the blade surface.
They get dirty easily, but because each blade is not fixedly arranged to accommodate changes in the angle of sunlight and is flexible, it has a structure that is extremely difficult to clean.

Therefore, in the past, blinds had to be cleaned manually by wearing gloves, applying detergent or the like to the gloves, and wiping both sides of each blade with the gloves. Therefore, the cleaning operation is extremely inefficient and even damage to the blade may occur during cleaning.

Therefore, in order to automatically clean the blinds without manual operation, a blind cleaning device configured as shown in FIGS. 4 and 5, for example, is provided.
Proposed by the applicant.

In FIG. 4, the blind cleaning device 1 includes a blind supporting device 2 and a blind cleaning section 3. As shown in FIG. The blind support device 2 supports the blind B in a suspended state with its support arm 2a, and causes the support arm 2a to reciprocate in the vertical direction between a solid line position and a chain double-dashed line position using a drive device 2b. , the blind B is moved up and down at an appropriate period. The blind cleaning section 3 has a cleaning tank 4 capable of accommodating the blind B when the support arm 2a of the blind support device 2 is in the two-dot chain line position, that is, in the lowered position of the blind B.

Near the upper end of the cleaning tank 4, cleaning brushes 5 and 6 are disposed facing each other along the longitudinal direction so as to sandwich the blind B from both sides, and these cleaning brushes 5 and 6 are not shown. The cleaning brushes 5, 6 are horizontally reciprocated in opposite directions along the longitudinal direction as indicated by arrows P and Q by a known driving means, and are moved along the upper sides of the cleaning brushes 5, 6 onto the cleaning brushes 5, 6. Pipes 7 and 8 having nozzles for spraying water or the like are arranged parallel to each other.

According to the blind cleaning device 1 configured as described above, cleaning of the blind B is performed as follows. That is, first, the cleaning tank 4 is filled with a cleaning liquid (detergent liquid or simply fresh water, etc.), and the blind B is mounted on the support arm 2a of the blind support device 2.
Attach to. At this time, the blind B is in the position shown by the solid line in FIG.

Next, the support arm 2a of the blind support device 2
is reciprocated in the vertical direction by the drive device 2b,
As a result, the blind B is lowered and the cleaning tank 4
into the cleaning liquid inside and then lifted up. At this time, the cleaning brushes 5 and 6 are horizontally reciprocated along the longitudinal direction of the blind B in opposite directions, that is, in the directions of arrows P and Q in FIG. 5, while sandwiching the reciprocating blind B from both sides. Then, the blind B is cleaned by brushing the surface of each blade of the blind B. Since the blade surface is already immersed in the cleaning liquid in the cleaning tank 4, this brushing removes dust and the like attached to the surface.

Thereafter, depending on the degree of contamination of the cleaning liquid, the cleaning liquid in the cleaning tank 4 is discharged from the cleaning tank 4,
The blind B is rinsed by introducing fresh water into the cleaning tank 4 through the nozzles 7 and 8.

However, in the blind cleaning device configured in this way, the support arm 2a of the blind support device 2 moves up and down while supporting the entire blind B in a suspended state, thereby lowering the blind into the cleaning tank 4. Because the blind support device is designed to rise from the cleaning tank, the height of the blind support device becomes very high.
Installation space for the blind cleaning device 1 is also required above. In particular, since it is tall when it is loaded onto the bed of a truck and moved, it is necessary to transport it with the blind support device 2 removed and reassemble the blind support device before use. Installation work is no longer easy, and in consideration of strength, the support arm 2a of the blind support device 2 is made of iron, for example.
It is extremely heavy, making it even more difficult to move and install it.

[Purpose of invention]

Therefore, an object of the present invention is to have a relatively low overall structure, so that the installation space is relatively small and it can be easily transported when moving.
An object of the present invention is to provide a blind cleaning device that can automatically clean blinds.

[Means and actions for solving problems]

According to the present invention, the present invention comprises a blind support device for supporting the blind in an expanded state and reciprocating the blind in the vertical direction relative to a cleaning tank, and a cleaning section for the blind, the cleaning section for the blind comprising: a cleaning tank accommodating the blind in the lowered position of the blind and capable of being filled with cleaning liquid;
cleaning brushes disposed opposite to each other along the longitudinal direction in the cleaning tank so as to sandwich the blind from both sides and horizontally reciprocated in opposite directions along the longitudinal direction; As the blind moves up and down in the cleaning tank,
In the blind cleaning device, the blind blade surface immersed in the cleaning liquid is brushed by a cleaning brush, wherein the blind support device is disposed on one side of the cleaning tank and has a central axis extending in the longitudinal direction. It is composed of a cylindrical rotating drum equipped with a hook part for locking the blind in a cylindrical shape, and by rotating this rotating drum around a central axis, the blind can be fixed at least in the upper area of the cleaning tank. This is achieved by reciprocating in the vertical direction.

According to this invention, the cleaning of the blind can be automatically and easily and reliably performed, and the blind support device that moves the blind up and down to insert and remove the blind into the cleaning tank is equipped with a rotating drum while the blind is in the unfolded state. The blind is supported by wrapping it around the drum, and by rotating the rotating drum in this state, the blind is reciprocated in the vertical direction on one side of the rotating drum, so the blind supporting device is relatively low. Since the blind is supported by the entire cylindrical surface of the rotary drum, the strength of the rotary drum itself may be relatively low and may be made of plastic, for example.

〔Example〕

Hereinafter, the present invention will be explained in more detail based on the embodiments shown in the drawings.

1 and 2 show an embodiment of a blind cleaning device according to the present invention, and the blind cleaning device 10 includes a blind support device 11 and a blind cleaning section 12.

The blind supporting device 11 is arranged on one side of a cleaning tank to be described later, and is constituted by a rotating drum 11a made of, for example, plastic and having a central axis extending in the longitudinal direction. It is provided with a hook portion 11b for locking. This hook portion 11b
As shown in FIG. 3, this includes a locking plate 11e that is pressed by a compression spring 11d against a plate-shaped substrate 11c that protrudes radially from the surface of the rotating drum 11a. Locking plate 1
The head box H of the blind B is sandwiched and fixedly held between the blind B and the blind B.

In this way, the blind supporting device 11 locks the head box H of the blind B with its hook portion 11b, thereby supporting the blind B by wrapping it around the cylindrical surface of the rotating drum 11a in the unfolded state, and also supporting the blind B by the driving device. 11f rotates the rotating drum 11a around its central axis, the blind B is reciprocated in the vertical direction between the solid line position and the two-dot chain line position in an area on one side of the rotating drum 11a. The blind B is moved up and down at an appropriate period.

Note that the drive device 11f is configured to transmit rotational torque from a motor capable of forward and reverse rotation to the rotating drum 11a via a transmission mechanism such as a belt, gears, or chain, but it cannot rotate only in one direction. Needless to say, the rotational torque from the motor may be switched using gears.

Furthermore, as a means for rotationally driving the rotating drum 11a, it is of course possible to manually drive the rotating drum 11a by attaching a grip portion to the central axis of the rotating drum 11a, without using the drive device 11f.

The blind cleaning unit 12 cleans the blind B at the lowered position, similar to the conventional example shown in FIG.
It has a cleaning tank 13 that can accommodate. Near the upper end of the cleaning tank 13, cleaning brushes 14 and 15 are disposed facing each other along the longitudinal direction so as to sandwich the blind B from both sides, and these cleaning brushes 14 and 15 are not shown. It is horizontally reciprocated in mutually opposite directions along the longitudinal direction by a known driving means, and has nozzles along the upper sides of the cleaning brushes 14 and 15 for spraying cleaning water and the like onto the cleaning brushes 14 and 15. The tubes 16, 17 are arranged parallel to each other.

The embodiment of the blind cleaning device according to the present invention is constructed as described above, and according to this blind cleaning device 10, the cleaning of the blind B is performed as follows.

That is, first, the cleaning tank 13 is filled with cleaning liquid, and the head box H of the blind B is fixedly held on the hook portion 11b of the rotating drum 11a.
By wrapping the blind B along the cylindrical surface of the rotating drum 11, the blind B is supported by the blind supporting device 11. At this time, the blind B is in the position shown by the solid line in FIG.

Next, the rotary drum 11a of the blind support device 11 is rotated by the arrow X by the drive device 11f or manually.
By being rotated in the direction, the blind B is reciprocated in the vertical direction in the area on one side of the rotating drum 11, whereby the blind B descends and enters the cleaning liquid in the cleaning tank 13, Subsequently, the rotary drum 11a is rotated in the direction opposite to the arrow X, thereby raising the blind B, and this vertical movement is repeated at a constant cycle.

At that time, the cleaning brushes 14 and 15 are horizontally reciprocated in mutually opposite directions along the longitudinal direction while sandwiching the vertically reciprocating blind B from both sides, thereby brushing the surface of each blade of the blind B. Blind B is cleaned using the following steps. Since the blade surface of this blind B has already been immersed in the cleaning liquid in the cleaning tank 13, dust and the like adhering to the surface are removed by this brushing.

Thereafter, if necessary, the cleaning liquid in the cleaning tank 13 is discharged from the cleaning tank 13, and fresh water is introduced into the cleaning tank 13 through the nozzles 16 and 17, thereby rinsing the blind B.

If the surface of the rotating drum 11 is formed into a structure with gaps such as a lattice-like structure, water can be drained at the same time when the blind B is rolled up after washing, and a dryer or the like can be installed inside or adjacent to the rotating drum 11. If this is provided, the blind B can be dried even more quickly after being washed.

[Effect of idea]

As described above, according to the blind cleaning device of the present invention, the blind support device that supports the blind in an expanded state and moves it back and forth in the vertical direction with respect to the cleaning tank is disposed on one side of the cleaning tank. It is composed of a cylindrical rotating drum having a central axis extending in the longitudinal direction and having a hook portion on its cylindrical surface for locking a blind, for example, a head box, and by rotating the rotating drum. Since the blind is configured to be reciprocated in the vertical direction at least in the upper area of the cleaning tank, the cleaning of the blind can be easily and reliably performed automatically, and the blind can be moved in and out of the cleaning tank. A blind support device that moves the blind up and down supports the blind by wrapping the blind in an expanded state around a rotating drum, and moves the blind vertically on one side of the rotating drum by rotating the rotating drum. Because I made it have a reciprocating motion,
The overall height of the blind support device can be designed to be relatively low.

Furthermore, since the blind is supported over the entire cylindrical surface of the rotating drum, the strength of the rotating drum itself may be relatively low and may be made of plastic, for example, and its surface structure may be modified for an appropriate period of time. If the blind is formed in a lattice shape or the like, the blind can be rolled up and drained at the same time.

Thus, according to the present invention, it is possible to provide an extremely excellent blind cleaning device that requires a relatively small installation space and can be easily transported due to its relatively low overall height. .
