DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a blind washing apparatus for automatically washing a so-called venetian blind or the like having a multiplicity of horizontally extending blades which are arranged one over another in vertically spaced relation to each other.
BACKGROUND ART
Generally, a so-called venetian blind having a multiplicity of horizontally extending blades arranged one over another in vertically spaced relation to each other has widely been employed on a window of a room or the like in order to keep off the sun. In such blind, the dust and nicotine of tobacco are apt to adhere to the surfaces of the respective blades so that the blind is promptly contaminated. However, the blind is so constructed as to be extremely difficult to be washed, because each blade is not fixedly mounted in order and because each blade has flexibility.
Because of the above reason, washing of the blind is conventionally a hand-washing or hand-scrubbing operation in which gloves are worn and detergent or the like is applied to the gloves for wiping off both sides of each blade. Accordingly, the washing operation is extremely inefficient, and there is the possibility that the blades may be damaged during the washing. Accordingly, treatments of the blind such as cleaning, washing and the like are not infrequently carried out.
It is therefore an object of the invention to provide a novel blind washing apparatus capable of automatically washing the above-described blind without relying upon troublesome manual operation.
DISCLOSURE OF THE INVENTION
According to the invention, the above object is achieved by a blind washing apparatus comprising a washing section for washing a blind, and a blind support device for supporting the blind in a developed manner and for reciprocating the blind vertically relatively to the blind washing section, wherein the blind washing section includes a washing tank accommodating the blind at a lowered position thereof and capable of being filled with washing liquid, and a pair of washing brushes arranged in opposed relation to each other substantially along a longitudinal direction so as to clamp the blind from its opposite sides within the washing tank, and wherein surfaces of blades of the blind dipped in the washing liquid are brushed by the washing brushes with the vertical movement of the blade, thereby carrying out washing of the blind.
The blind washing apparatus according to the invention may be so arranged that nozzles are arranged in the vicinity of an upper end of the washing tank along the longitudinal direction thereof, and the washing liquid within the washing tank is injected to the blind through the nozzles.
Further, the aforesaid blind washing section may be so arranged that a second tank is provided for storing detergent liquid, the detergent liquid is transferred from the second tank to the washing tank at the beginning of a washing step of the blind, and the detergent liquid is returned from the washing tank to the second tank at the end of the washing step of the blind. Moreover, a third tank may be arranged for storing washing water. Nozzles are arranged above and along the washing brushes, and the washing water from the third tank is injected to the vertically moving blind through the nozzles after the washing step of the blind by the detergent liquid, thereby carrying out rough rinsing of the blind. Furthermore, a fourth tank may be arranged for storing new water, and the new water from the fourth tank is injected toward the vertically moving blind through the nozzles after the injection of the washing water, thereby carrying out finishing rinsing.
The term "washing liquid" in this specification is used to mean any one of the aforesaid detergent liquid, washing water or the new water for rinsing, or is used as a general term for them.
According to this invention, washing of the blind, which has conventionally been incapable of being done without relying upon the manual operation, can be performed automatically simply and reliably. In particular, if the a
