Description

  The present invention relates to a cleaning apparatus using ozone water, and more particularly to a cleaning apparatus suitable for sterilizing and cleaning a human body part such as a finger.

  In various school facilities and hospitals, hand washing is mandatory for hygiene purposes. Conventional methods for hand-washing are generally a method using a detergent such as soap, or a method using a chemical such as cresol or ethyl alcohol.

However, since the workers of the above facilities need to wash their hands complicatedly, rough hands are a problem. On the other hand, the effect of washing using soap or sanitizing alcohol depends on individual differences (how to wash, etc.) of the person to be washed, and complete washing is not necessarily expected.
Thus, in recent years, various hand-washing cleaning devices that use ozone water that can suppress rough handing and have a high sterilizing effect have been developed (see Patent Documents 1 and 2).

(First embodiment of the present invention)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
First, the configuration of the cleaning device will be described.
FIG. 1 shows the appearance of the cleaning apparatus, and FIGS. 2 and 3 show the internal configuration of the cleaning apparatus.
The cleaning apparatus includes a housing 1, an ozone water spraying unit housed in the housing 1, an ozone water recovery unit that collects the dispersed ozone water, and an ozone gas generated in the housing 1 that decomposes the outside. And an ozone gas circulation unit that collects ozone gas generated in the housing 1 and circulates the ozone gas again in the housing.

The housing 1 is made of a material having corrosion resistance to ozone (for example, a synthetic resin such as polyester, a material coated with glass, or the like), and is formed in a box shape.
A circular insertion port 2 for inserting a hand is opened on the front side wall surface of the housing 1. In addition, the opening shape of the insertion port 2 may be an ellipse or a rectangle.

  The inner peripheral end face of the insertion port 2 is formed in a tapered shape when viewed in cross section so that the diameter gradually decreases toward the inner periphery of the housing 1. A plurality of circulating ozone gas injection ports 3 arranged at radial positions are provided on the inner peripheral surface of the insertion port 2. The circulating ozone gas injection port 3 is directed to the inside of the housing 1 and can eject ozone gas into the housing 1.

The ozone water spraying unit includes an ozone water supply device 4 that generates ozone water, and an injection port 3 that sprays ozone water supplied from the ozone water supply device 4 to sites to be sterilized such as hands.
The ozone water recovery unit has a waste liquid recovery hopper 5 provided in the lower part of the housing 1 and a discharge port 6 for discharging the waste liquid recovered by the hopper 5 to the outside.

  The ozone gas discharge unit includes a pipe 12 arranged from the inside of the housing 1 to the outside, an ozone adsorber 7 provided in the middle of the ozone gas intake port 12, and air cleaned by the ozone adsorber 7. An exhaust pump 13 that sucks (discharges oxygen gas from ozone gas) and discharges it to the outside through the discharge port 8 is configured. By the suction action of the pump 13, the inside of the housing 1 is in a negative pressure state with respect to the external pressure of the housing 1.

In the ozone adsorber 7, an ozone adsorbent such as activated carbon is enclosed.
The ozone gas circulation unit is composed of two circulation systems, a first circulation system and a second circulation system.
The first circulation system is a system that recirculates ozone gas in the housing 1 in the housing.

  As shown in FIG. 3, the first circulation system includes the blower fans 17 and 18 for circulating ozone gas provided on the left and right side walls in the case 1, and guides provided on the front and rear inner walls in the case 1. 19, 20, 21, 22. In this first circulation system, as indicated by arrows in FIG. 3, the ozone gas in the housing 1 is driven from the central portion in the housing 1 → the rear wall → the guides 19 and 20 → left and right by driving the blower fans 17 and 18. The air is forcedly circulated so as to return to the central portion in the housing 1 again through the path of the side walls → the blower fans 17 and 18 → the front wall guides 21 and 22. The circulation of ozone gas inside the housing 1 can improve the sterilization effect by ozone gas in addition to the sterilization by ozone water. Moreover, since the ozone gas recirculation direction is always directed toward the inside of the housing, the outflow of ozone gas from the insertion port 2 can be suppressed.

  The second circulation system is a system that once sucks ozone gas in the housing 1 and forcibly blows the sucked ozone gas into the housing again through the circulation ozone gas injection port 3 of the insertion port 2.

  As shown in FIG. 2, the second circulation system includes an ozone gas intake port 12 provided on the rear wall of the housing 1, a pipe 15 branched from the pipe, and a pump 14 installed in the pipe 15. And a plurality of injection ports 3 provided in the inlet 2.

  As shown in FIG. 3, the suction ozone gas is distributed to the plurality of injection ports 3 through piping arranged along the inner periphery of the insertion port 2. Since ozone gas injected from each injection port 3 is forcibly supplied by the pump 14, it becomes a jet jet. The injection strength of the injection port 3 is set by appropriately selecting the inner diameter of the tip of the injection port 3.

Although not shown, by adopting a configuration in which the injection direction of the injection port 3 can be adjusted appropriately, it becomes possible to adjust the injection direction optimal for preventing the ozone gas from leaking afterwards.
In addition, the housing 1 is provided with a sensor (detection unit) 24 that detects whether or not a site to be cleaned exists, and a control unit 9.

Based on the detection signal from the sensor 24, the control unit 9 controls the driving of the ozone pure water supply device 4, the ozone gas discharge pump 13, the blower fans 17 and 18, and the circulation pump 14.
As the control unit 9, a microcomputer can be used. The microcomputer includes a CPU, a ROM, a RAM as a work area, an input port for inputting a detection signal from the sensor 24, an ozone pure water supply unit 4, an ozone gas discharge pump 13, blower fans 17, 18 and And an output port for sending a drive control signal to the circulation pump 14. The microcomputer expands the operation sequence program (FIG. 4) stored in the ROM to the RAM, and controls each part in an integrated manner by cooperation of the expanded operation sequence and the CPU.

In place of the microcomputer, a dedicated IC such as an ASIC configured by the logic of the same operation sequence may be used.
As the sensor 24, an optical sensor (photocoupler or the like) subjected to waterproofing treatment can be used.

Next, a series of operations of the cleaning apparatus will be described.
FIG. 4 shows an operation sequence executed by the control unit 9.
First, when a hand is inserted from the insertion port 2, the sensor 24 detects the hand (step S1: YES). Receiving this detection signal, the controller 9 drives the ozone water supply device 4 (step S2) and sprays ozone water from the spray nozzle 10.

  Next, the control unit 9 activates the exhaust pump 13 (step S3), turns on the ultraviolet lamp 23 (step S4), activates the blower fans 17 and 18 (step S5), and activates the pump 14.

  Here, when the blower fans 17 and 18 are activated, the ozone gas in the housing 1 is circulated in the direction indicated by the arrow as shown in FIG. And since the injection port 3 is drawn in by the jet jet which goes inward of the housing | casing 1, and is returned in a housing | casing again, the leakage of ozone gas from the insertion port 2 can be prevented. In addition to the sterilization effect of ozone water by the circulation of ozone gas, the sterilization effect of ozone gas is also superimposed, so that the sterilization effect can be further enhanced.

  Next, when a predetermined cleaning time has elapsed (step S7: YES), the supply of ozone water is stopped by stopping the ozone water supply device 4 (step S8), the discharge pump 13 is stopped (step S8), and the ultraviolet lamp 23 is turned off. (Step S10), the blower fans 17 and 18 are stopped (S11), and the pump 14 is stopped (Step S12).

  Next, in step S13, it is detected whether or not the power is turned off. If YES, the operation of the cleaning device is stopped. If NO, the operation returns to step S1 and the next cleaner's hand is inserted. Wait for.

  In the present embodiment, the human hand has been described as an example of the part to be sterilized and washed, but it may be a foot. In addition, the aspect suitably modified or deformed so as to be suitable for foot sterilization and disinfection as necessary belongs to the technical scope of the present invention.

  The dryer 25 can be directly sprayed onto the hand to be cleaned. In addition to the direct injection, the dryer 25 is connected to the pipe 15 via a branch valve (not shown) by a connection pipe (not shown), and is to be cleaned from the injection port 3 via the pipe 15. The hand cleaned with ozone water can be quickly dried by spraying drying air such as warm air onto the hand.

  Next, a series of cleaning operations based on the above configuration will be described. As in the operation of the first embodiment, the cleaning device according to the present embodiment is executed from step S1 to step S8, and after this step S8, the dryer 25 is activated, and the housing 1 is inserted into the insertion port 2. Hot air is jetted into the inserted hand to be cleaned (step S81).

  The controller 9 determines whether or not the warm air injection has passed a predetermined drying time (step S82). If it is determined that the predetermined drying time has elapsed, the dryer 25 is turned on. The controller 9 stops (step S83). While the dryer 25 is supplying air for drying such as hot air, the exhaust pump 13, the ultraviolet lamp 23, the blower fans 17, 18 and the pump 14 are all in the activated state and remain. Drying air such as warm air is discharged to the outside through the exhaust port 8 together with ozone. Further, after the dryer 25 is stopped in step S83, steps S9 to S13 are executed and completed in the same manner as in the first embodiment.
