BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disinfecting and bleaching apparatus for disinfecting and bleaching a cloth for wiping a table or the like.

[0002]

2. Description of the Related Art Conventionally, chlorine-based chemicals have been used for sterilizing and bleaching a cloth for wiping a table or the like. However, increasing the chlorine concentration to improve the germicidal and bleaching abilities of chemicals may cause skin roughness. It takes a long time for bacteria and bleaching. Some bacteria have excellent resistance to chlorine, and in some cases, cannot be killed by chlorine-based chemicals.

Accordingly, an object of the present invention is to provide a disinfecting and bleaching treatment apparatus which can more reliably disinfect and bleach a cloth for wiping a table or the like in a short time and can prevent rough skin. Aim.

[0004]

Means for Solving the Problems and Effects of the Invention In order to achieve such an object, a sterilization and bleaching apparatus for a cloth according to the present invention comprises: an ozone water generating means for generating ozone water;
Conveying means for conveying the cloth, supplying means for supplying the ozone water generated by the ozone water generating means to the cloth conveyed by the conveying means, and ozone water from the cloth supplied with the ozone water by the supplying means. And removing means for removing.

In the apparatus for removing bacteria from a cloth according to the present invention, a cloth for wiping a table or the like is transported to a predetermined position by a transport means, and ozone water is supplied by a supply means. Then, after being sterilized and bleached with ozone water, the ozone water is removed by removing means. In addition,
The transport means may be configured to operate by a motor or the like, or may be configured to be manually operated by an operator.

As described above, according to the apparatus for sterilizing and bleaching a cloth according to the present invention, by supplying ozone water to the cloth, sterilization and bleaching can be performed reliably in a short time. Further, since the ozone water is finally decomposed into oxygen and water, there is no possibility that the wastewater will adversely affect the environment. Furthermore, ozone water can be produced with oxygen, water and a small amount of electric power, and is therefore less expensive than chlorine-based chemicals. in addition,
When supplying ozone water to the cloth, and when removing ozone water from the cloth, there is no need to touch the ozone water, so that the skin is not roughened. The concentration of ozone gas in the ozone water is preferably in the range of 0.05 to 5.00 ppm, and more preferably in the range of 0.20 to 1.00 ppm. When such a concentration is used, even though sufficient sterilization and bleaching ability can be obtained, the skin is not roughened even if touched by hand.

According to a second aspect of the present invention, in the apparatus for sterilizing and bleaching a cloth according to the present invention, the conveying means is constituted by a belt conveyor which can convey the cloth with the cloth spread. Is also good. In such a case, the supply means can make ozone water evenly contained in the whole spread cloth. If the ozone water supplied by the supply means overflows without absorbing the cloth width or is scattered around the cloth width and remains on the belt conveyor, the efficiency of removal by the removal means may be reduced. So, for example, by forming a hole in the belt constituting the belt conveyor,
Alternatively, it is more preferable that the belt is formed in a net shape so that excess ozone water does not remain on the belt conveyor.

[0008] As described in claim 3, the supply means may supply the ozone water by spraying the cloth conveyed by the conveyance means. In the case where the apparatus for disinfecting and bleaching a cloth according to the present invention is configured as described above, the supply means can supply even a small amount of ozone water over a wide range. Can be reduced.

Further, as described in claim 4, the removing means may be constituted by a roller for pressing the cloth carried by the carrying means. In such a case, the cloth conveyed by the conveying means is squeezed by being gradually wrapped around the roller from the end to remove excess ozone water. Therefore, ozone water can be efficiently removed with a simple configuration. In addition, as a specific method of squeezing the cloth width, for example, a method in which the cloth width is sandwiched between two rollers from the top and bottom of the cloth width can be cited. There are also methods. Since ozone water slightly remains in the cloth thus squeezed in this manner, the table and the like can be sterilized by wiping the table with the cloth. Further, a heating unit or a blowing unit may be provided, and after the cloth is squeezed, a heating process or a blowing process may be further performed. With this configuration, the cloth width can be completely dried, so that it can be used for wiping a table or the like.

A drainage collecting dish 60 for collecting ozone water, and an ozone gas remover 7 for removing ozone gas from the ozone water collected in the drainage collecting dish 60
0, an ozone gas decomposer 80 for decomposing ozone gas removed by the ozone gas remover 70 into oxygen, and a tray 90.

The ozone gas generator 10 is a well-known device that generates ozone gas from oxygen by plasma discharge. The ozone gas can be generated not only by plasma discharge but also by creeping corona discharge, but these methods are generally well-known and will not be described in detail.

The ozone gas mixer 20 is a well-known device that generates ozone water by injecting and dissolving ozone gas into water. The amount of the ozone gas ejected so that the ozone gas concentration in the ozone water becomes about 1.00 ppm. Is set. The belt conveyor 30 is composed of a driving wheel 31 connected to a motor (not shown), a driven wheel 33 driven by the driving wheel 31, a belt 35 formed in a mesh shape, and the like. The part to be made is made of stainless steel. In addition, even if it is other than stainless steel, synthetic resin etc. can also be employ | adopted if it is excellent in resistance to ozone water. Further, instead of forming the belt 35 in a net shape, holes may be provided to allow ozone water to pass therethrough.

The roller 50 is supported by a spring 51 while being biased toward the driven wheel 33 of the belt conveyor 30. The ozone gas remover 70 drives out the ozone gas dissolved in the ozone water by heating the ozone water.

The ozone gas decomposer 80 is a known device that oxidizes ozone gas using manganese dioxide and decomposes it into oxygen. In addition, the disinfecting bleaching apparatus 1 for the cloth of this embodiment
, The ozone gas generator 10 and the ozone gas mixer 2

Further, the ozone gas removed from the ozone water is decomposed into oxygen by the ozone gas decomposer 80 and discharged.

Next, the effect of the apparatus 1 for removing bacteria from a cloth will be described. Apparatus for disinfecting bleaching cloth 1 of this embodiment
Can surely disinfect and bleach the cloth X with ozone water in a short time. Further, since the ozone water is finally decomposed into oxygen and water, there is no possibility that the wastewater will adversely affect the environment. Furthermore, ozone water can be produced with oxygen, water and a small amount of electric power, and is therefore less expensive than chlorine-based chemicals. In addition, when supplying ozone water to the cloth,
Also, when removing ozone water from the cloth, there is no need to touch the ozone water, so that the skin is not roughened.

Since the cloth X is conveyed in a state of being spread on the belt conveyor 30, ozone water is sprayed evenly on the entire cloth X by the shower, and the bacteria elimination and bleaching are effectively performed. Further, the belt 35 is formed in a mesh shape, and the ozone water overflowing without absorbing the cloth X, the ozone water scattered around the cloth X, and the ozone water squeezed by the roller 50 are quickly drained and collected. Since it falls to 60, ozone water can be removed efficiently.

Further, since a small amount of ozone water can be spread over a wide area by the shower 40, the amount of ozone water used can be reduced. In addition, since excess ozone water is squeezed out of the cloth X by the roller 50, ozone water can be efficiently removed with a simple configuration. In addition, since the roller 50 is urged downward by the spring 51, even if the thickness of the cloth width X varies, it can be pressed efficiently.

As described above, an example has been described to explain the embodiment of the present invention. However, the present invention is not limited to this example, and may be implemented in various modes. Of course. For example, in the present embodiment, the ozone water collected by the drainage collection tray 60 is treated to drain and exhaust, but the drainage collection tray 6
The ozone water collected at 0 may be filtered using a stainless steel three-dimensional structure filter or the like, for example, and ozone gas may be slightly added and used. With such a configuration, it is possible to reduce the amount of ozone gas generated (that is, the amount of power used) and the amount of tap water used,
Disinfection and bleaching of the cloth can be performed at lower cost.

In this embodiment, the ozone water is sprayed from the shower 40 and sprayed on the cloth X. However, the ozone water is stored in a water tank, and the cloth X is adjusted by the belt conveyor. By being transported inside,
The cloth X may be configured to absorb ozone water.

Further, in this embodiment, the roller 50 is supported in a state of being urged downward by the spring 51. However, for example, an apparatus is installed in a hospital, a nursing home, or the like, and a uniform width cloth is provided. If used, the roller 50 may be fixed at a position where the interval between the roller 50 and the belt 35 is an interval corresponding to the thickness of the cloth width X. With such a configuration, the structure around the roller 50 becomes very simple. Further, the roller 50 may be configured to be able to be moved up and down by a human hand from the outside, and the roller 50 may be configured to be urged downward by the force of a human hand. In the case of such a configuration, the squeezing can be efficiently performed by increasing or decreasing the force of the hand according to the thickness or the material of the cloth width X.

Further, a heating means or a blowing means may be provided, and after the cloth is squeezed, a heating treatment or a blowing treatment may be further performed. With this configuration, the cloth width can be completely dried, so that it can be used for wiping a table or the like.
