Description

The present invention relates to a cleaning device capable of cleaning (including sterilization, sterilization, etc.) of fingers and the like (objects to be cleaned).

Various devices for cleaning or sterilizing have been proposed in order to raise hygiene awareness and prevent infectious diseases caused by various bacteria and viruses. In particular, a device has been proposed in which washing and draining (including drying) after washing are performed in the same storage chamber (washing tank) so that moisture or the like after washing does not scatter around the place where the device is installed. A related description is found in the following patent documents.

Japanese Unexamined Patent Publication No. 2000-60763 Japanese Unexamined Patent Publication No. 2012-12017

Patent Document 1 proposes a hand-washing / drying device that dries the washed hands by blowing air as it is after ejecting the washing mist into the hands placed in the insertion portion.

Patent Document 2 proposes a hand washing / drying device in which 0.5 to 10 cc of hypochlorous acid water having a pH of 6 to 7 is sprayed at a time for washing, and then dried with air containing ozone.

In either case, the amount of cleaning liquid supplied at one time is very small, and it cannot be said that the cleaning property or sterilizing property is sufficient. Further, Patent Document 1 does not have a specific description regarding the cleaning liquid. The slightly acidic hypochlorous acid water having a pH of 6 to 7 used in Patent Document 2 has a low abundance ratio of hypochlorous acid (HClO or HOCl) effective for sterilization, and is efficient in a very small amount as described above. Cannot be washed or sterilized.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a cleaning device different from the conventional device.

As a result of diligent research to solve this problem, the present inventor has a cleaning solution having a high abundance ratio of hypochlorous acid having excellent bactericidal activity on the premise that hands and the like are washed and drained (dried) in a common sink. We conceived a device that efficiently performs reliable sterilization, etc. by supplying a relatively large amount of water to the object to be cleaned. By embodying this idea, the present invention described below has been completed.

《Washing device》
(1) The cleaning apparatus of the present invention has a sink having an insertion port for taking in and out the cleaning target, accommodating the cleaning target, and having a discharge port for discharging the used cleaning liquid, and a cleaning means for discharging the cleaning liquid into the sink. When, a cleaning apparatus and a blowing means for supplying air to said sink in, the cleaning means, the cleaning solution diluted hypochlorite solution mixed with dilution water to the high concentration hypochlorous acid water discharged as the high-concentration hypochlorous acid water, it is preferable to supply housed in replacement freely cartridge tank.
The cleaning apparatus of the present invention includes a sink having an insertion port for taking in and out the cleaning object, capable of accommodating the cleaning object, and a discharge port for discharging the used cleaning liquid, and a cleaning means for discharging the cleaning liquid into the sink. A cleaning device including an air supply means for supplying air into the sink and at least a control means for controlling the operation of the cleaning means. The cleaning means is a mixture of high-concentration hypochlorous acid water and diluted water. Diluted hypochlorous acid water is discharged as the cleaning liquid, and the control means operates the cleaning means for a predetermined time at a predetermined time when the cleaning target is not inserted in the sink and discharges the cleaning liquid to the sink. It is advisable to perform a self-cleaning mode.
The cleaning apparatus of the present invention includes a sink having an insertion port for taking in and out the cleaning object, capable of accommodating the cleaning object, and a discharge port for discharging the used cleaning liquid, and a cleaning means for discharging the cleaning liquid into the sink. A cleaning device including an air supply means for supplying air into the sink and an ozone supply means for supplying ozone to the sink. The cleaning means is a dilution of high-concentration hypochlorous acid water mixed with diluted water. Hypochlorite water may be discharged as the cleaning liquid, and the ozone supply means may supply ozone to the sink when the cleaning target is not in the sink.

(2) The cleaning apparatus of the present invention first provides the above-mentioned cleaning means and air supply means to perform cleaning of the cleaning target and drainage (drying) for removing the cleaning liquid from the cleaning target in the same sink (cleaning tank). ) Can be done. Therefore, the surrounding area where the cleaning device is installed is not wet with water droplets or the like, and the environment of the surrounding space where the device is installed can be maintained in a hygienic state.

Next, in the cleaning apparatus of the present invention, high-concentration hypochlorous acid water is diluted with clean water or the like before use. Therefore, the degree of freedom in adjusting the concentration and supply amount of the cleaning liquid supplied to the cleaning target at the time of cleaning can be increased. For example, according to the cleaning apparatus of the present invention, a relatively large amount of cleaning liquid can be poured over the cleaning target to sufficiently wash away the bacteria and the like adhering to the cleaning target while sterilizing them. Further, even if a large amount of cleaning liquid is used at one time, the frequency of replenishing or replacing high-concentration hypochlorous acid water can be reduced if the environment is such that diluted water is replenished at any time.

Further in the cleaning apparatus of the present invention is not a high-concentration hypochlorous acid water per se, is used a cleaning liquid consisting of dilute hypochlorous acid water. Hypochlorous acid (HClO), which exerts a high bactericidal effect, maximizes (or maximizes) the abundance ratio in an aqueous solution having a pH of 4 to 6 and even a pH of 4.5 to 5.5. Therefore, according to the cleaning apparatus of the present invention, it is possible to perform cleaning and sterilization by effectively utilizing hypochlorous acid while suppressing the amount of high-concentration hypochlorous acid water used.

《Others》
(1) The high-concentration hypochlorite water referred to in the present specification means hypochlorous acid water which is a raw material used for preparing diluted hypochlorous acid water obtained by diluting it with water. High-concentration hypochlorous acid water and diluted hypochlorous acid water can be clearly distinguished from each other by the difference in pH. Therefore, the specific concentration of high-concentration hypochlorous acid water does not matter.

Speaking of the concentration, it is preferable that the high-concentration hypochlorous acid water has an effective chlorine concentration of 500 mg / L or more, 1000 mg / L or more, and further 1500 mg / L or more. From the viewpoint of productivity and controllability, the effective chlorine concentration is preferably 2500 mg / L or less, more preferably 2000 mg / L or less. The diluted hypochlorous acid water is, for example, diluted 10 to 100 times, 20 to 60 times, and 30 to 50 times the high concentration hypochlorite water, and the effective chlorine concentration is 5 to 100 mg / L, 10 to 10. It is preferably 80 mg / L, more preferably 20 to 60 mg / L.

The high-concentration hypochlorous acid water preferably has a pH of 6 (super) to 7, and more preferably 6.2 to 6.8. When the pH is increased, hypochlorous acid (HClO) can be changed to hypochlorite ion (ClO ⁻ ) or sodium hypochlorite having weak bactericidal activity. On the contrary, when the pH is lowered, chlorine gas (Cl ₂ ) can be generated. In either case, hypochlorous acid, which has strong bactericidal activity, is reduced and the effective chlorine concentration is lowered, which is not preferable.

By mixing high-concentration hypochlorous acid water and diluted water, hypochlorous acid in high-concentration hypochlorous acid water causes a disproportionation reaction (2HClO → 2HCl + O ₂ ). As a result, the diluted hypochlorous acid water shifts to the more acidic side than the high-concentration hypochlorous acid water, and the pH becomes pH 4 to 6 in which the abundance ratio of hypochlorous acid is high. By the way, hypochlorous acid water is a safe cleaning liquid (sterilizing liquid) that is produced by electrolyzing salt water or hydrochloric acid water and is also recognized as a food additive (sterilizing agent). However, the cleaning liquid according to the present invention may further contain other safe cleaning components or sterilizing components while containing hypochlorous acid as the main component (the component having the maximum concentration).

(2) Unless otherwise specified, "x to y" in the present specification includes a lower limit value x and an upper limit value y. A range such as "ab" may be newly established with any numerical value included in the various numerical values or numerical ranges described in the present specification as a new lower limit value or upper limit value.

It is external perspective view of the hand washing dry sterilizing apparatus which is one Example of this invention. It is a block diagram which shows the internal structure schematically. It is a flowchart which shows the operation (control).

One or more components arbitrarily selected from the present specification may be added to the components of the present invention described above. It can be a methodical component or a component of an object. Whether or not which embodiment is the best depends on the target, required performance, and the like.

<< Cleaning means >>
(1) The cleaning means according to the present invention sinks diluted hypochlorous acid water (cleaning solution) obtained by mixing high-concentration hypochlorous acid water (hereinafter, also simply referred to as "raw water") and diluted water. Discharge inward. The cleaning means includes, for example, a first pump that pumps and pumps high-concentration hypochlorous acid water, a second pump that pumps and pumps diluted water, and high-concentration hypochlorous acid water pumped from both pumps. Mixing from a mixer (joint) that mixes diluted water, a cleaning nozzle that discharges (spouts) diluted hypochlorous acid water to a sink, a first pipe that communicates from the first pump to the mixer, and a second pump. A second pipe for communicating with the pump and a third pipe for communicating from the mixer to the cleaning nozzle are provided.

The start and stop of the discharge of the cleaning liquid may be linked with the start and stop of each pump, or an on-off valve or the like may be provided separately. The discharge flow rate (ml / min) and dilution rate (mixing ratio of high-concentration hypochlorous acid water and diluted water) from the cleaning nozzle may be adjusted by adjusting the output (flow rate) of each pump itself, or the piping. A flow rate adjusting valve or the like may be arranged inside. It should be noted that the start / stop (on / off) of each pump and the control of the separately provided solenoid valve and the like are performed by the control means described later. Further, the first pump and the second pump are not limited to the case where they are composed of two independent pumps, and one pump may be used in combination.

(2) It is preferable that the high-concentration hypochlorous acid water is stored and supplied in a replaceable cartridge tank. As a result, it is not necessary to provide a hypochlorite water generator (electrolyzer), and the cleaning device can be made compact. It also facilitates maintenance and management of the cleaning equipment. It is preferable that the cartridge tank or the cleaning device is provided with a display means (including a remaining amount warning or the like) or a detection means for indicating the remaining amount of high-concentration hypochlorous acid water. The detection means provided in the cleaning device can be performed, for example, by detecting a change in the weight of the cartridge tank by the displacement of the load cell or the spring.

On the other hand, the diluted water is preferably supplied from the water supply or the water supply tank. As a result, a large amount of diluted water can be obtained at the place where the cleaning device is installed, and the degree of freedom in adjusting the flow rate and the dilution rate of the discharged cleaning liquid is increased. The term "tap water" as used herein is usually so-called tap water, but it is not limited to tap water as long as it is purified and sanitary water. The water supply tank may be an isolated water storage tank (reserve tank), or may be connected to the water supply. In the latter case, for example, if the communication between the water supply and the water supply tank is controlled by an on-off valve or the like, it is preferable that the water supply is appropriately replenished with clean water when the water level in the water supply tank drops. In addition to the solenoid valve, such an on-off valve may be a mechanical valve such as a ball tap type.

(3) It is preferable that the cleaning means discharges 150 to 1000 ml, 250 to 500 ml, and further 300 to 400 ml of the cleaning liquid per cleaning. If the discharge amount is too small, it cannot be sufficiently washed away with hypochlorite water, and the detergency and sterilization property may deteriorate. If the discharge amount is excessive, high-concentration hypochlorous acid water and the like will be wasted. The discharge time (washing time) per washing is preferably 10 to 30 seconds, more preferably 15 to 20 seconds. If the discharge time is too short, the cleaning property and sterilization property are deteriorated, and if the discharge time is too long, it is inefficient.

<< Means of air supply >>
The air supply means blows air into the sink to drain or dry at least the object to be washed that has been washed away with the washing liquid. The air supply means includes, for example, a blower that introduces air (outside air) from outside the housing of the cleaning device, and a duct that guides the air blown by the blower to the ventilation port (air supply port, air supply port or air nozzle) of the sink. One blower may be provided, but a plurality of blowers may be provided to secure the air volume. In addition, it is preferable that the air supply means is provided with a heating means that appropriately heats the air according to the outside air temperature and the like. The heating means may be various heaters, but for example, it is preferable to adopt a pressure heating type in which the air is compressed by the blowout pressure of the blower and the air temperature naturally rises, in order to save energy.

Further, it is preferable that a purification filter is provided on the upstream side of the blower. As a result, clean air is sent to the sink, and the cleaning target is prevented from being recontaminated when draining and drying. The purification filter is a filter that removes dust, dirt, bacteria, etc. from the air taken in by the blower, and preferably has appropriate performance according to the application and specifications of the cleaning device. For example, a HEPA filter (High Efficiency Particulate Air Filter), a ULPA filter (Ultra Low Penetration Air Filter), or the like as specified in JIS (Z8122) may be used.

《Ozone supply means》
It is preferable that the cleaning device of the present invention includes an ozone supply means for supplying ozone into the sink. This makes it possible to drain and dry after cleaning with clean air that has been sterilized with ozone. Also, except when draining and drying after cleaning (for example, when the object to be cleaned is not in the sink and the air supply means is stopped), the ozone supply means is activated to vent the sink (feed). By releasing ozone through the air vent), it is possible to perform air cleaning, sterilization, deodorization, etc. (hereinafter, these are referred to as "space cleaning") in the space where the cleaning device is installed. Further, organic substances (proteins, fats and oils, etc.) adhering to the inner wall surface of the sink can be decomposed by ozone. By decomposing organic substances and the like with ozone, self-purification, which will be described later, is more effectively promoted.

The ozone supply means includes, for example, an ozone generator, a fan that sends ozone generated by the ozone generator, and a conduit that guides ozone to the duct or sink of the air supply means. When ozone flows into the duct of the air supply means, it is preferable that the conduit is connected to the downstream side of the air supply means (particularly the blower). As a result, it is possible to avoid the promotion of deterioration of the blower due to ozone and the measures against ozone for the blower.

The above-mentioned fan can be omitted if the blower of the air supply means is operated with the conduit connected to the duct when supplying ozone (not limited to when draining or drying). This is because ozone naturally flows from the duct into the duct due to the negative pressure (Venturi effect) generated by the air flowing through the duct.

The amount of ozone supplied is preferably adjusted so that the ozone concentration in the installation space of the cleaning device is 0.02 to 0.06 mg / L, more preferably 0.03 to 0.05 mg / L. If the ozone concentration is too low, the effect of space cleaning and self-purification is poor, and if the ozone concentration is too high, it can cause discomfort to people. Although it depends on the size of the installation space, the amount of ozone supplied may be, for example, 1 to 10 mg / h or 2 to 6 mg / h. In an environment where the ozone concentration can rise abnormally, the ozone decomposition catalyst may be provided on the outside air intake side of the air supply means or the ozone supply means.

<< Control means >>
The control means controls the operation (start / stop, etc.) of each means. For example, when the cleaning target is inserted in the sink, the control means operates the cleaning means for a predetermined time to perform a cleaning mode in which the cleaning liquid is discharged to the cleaning target, and then further operates the air supply means for a predetermined time. A drying mode is performed in which the cleaning liquid adhering to the object to be cleaned is blown off by an air flow.

Further, the control means performs, for example, a self-purification mode in which the cleaning means is operated for a predetermined time to discharge the cleaning liquid to the sink at a predetermined time when the cleaning target is not inserted in the sink. Here, the ozone supply means may be started / stopped by the control means, but may be started / stopped simply in conjunction with turning on / off the power of the cleaning device. In the latter case, the ozone supply means is always in operation when the power is on, and ozone is discharged into the sink or the installation space of the cleaning device even when the water is not drained or dried. As a result, the space can be cleaned and self-purification can be promoted.

The reasons why ozone promotes self-purification are as follows. First, ozone oxidatively decomposes organic substances and the like adhering to the sink. When the cleaning liquid is supplied in this state, the hypochlorous acid water does not repel water due to organic substances and acts directly on bacteria and the like, and the sterilization effect by self-purification is enhanced.

《Others》
The cleaning device of the present invention can be installed in a food processing factory, a clean room, a hospital, a toilet, etc., and can be used for cleaning / sterilizing fingers / hands / arms (further space cleaning). The object to be cleaned is not limited to the human body such as fingers, but various objects such as medical instruments and sanitary instruments can be cleaned by adjusting the shape and size of the sink.

Taking up the hand washing and drying sterilizing device M (simply referred to as “washing and drying device M”) which is an embodiment of the washing device of the present invention, the present invention will be specifically described below.

"Constitution"
The appearance of the washing / drying device M is composed of a substantially rectangular parallelepiped housing 40 as shown in FIG. Above the housing 40 is a sink 41 which is a washing tank capable of accommodating fingers inserted from the insertion port 410, and below the front is an opening / closing door 42. The cartridge tank 110 of high-concentration hypochlorous acid water, which will be described later, can be taken in and out (replaced) through the opening / closing door 42. A control panel 50 is provided near the upper end of the housing 40, and an indicator, a power switch, and the like indicating the operating state of the washing / drying device M are arranged.

The internal structure of the washing / drying device M is schematically shown in FIG. The washing / drying device M includes a washing means, an air supply means, and an ozone supply means. The cleaning means are a pump 11 (first pump) that pumps high-concentration hypochlorous acid water in the cartridge tank 110 through the pipe 111, and a pump 12 (first pump) that pumps the clean water (diluted water) in the reserve tank 120 through the pipe 121. 2 pumps), a connecting portion 13 (mixer) that mixes high-concentration hypochlorous acid water pumped from the pump 11 through the pipe 112 and diluted water pumped from the pump 12 through the pipe 122, and a connecting portion 13 A cleaning nozzle 14 for ejecting the generated diluted hypochlorous acid water (cleaning liquid) into the sink through the pipe 131 is provided.

A water supply is piped to the side surface of the reserve tank 12 via a ball tap type automatic on-off valve. As a result, when the water level of the diluted water drops in the reserve tank 12, water is automatically replenished from the water supply into the reserve tank 12 until the diluted water reaches a predetermined water level. Further, a plurality of cleaning nozzles 14 are arranged above the wall surface on both sides of the sink 41. Then, the diluted hypochlorous acid water discharged from the cleaning nozzle 14 is drained from the discharge port of the sink 41 to the sewer or the like through the pipe 43. Although not shown, a heater may be installed in at least a part of the reserve tank 12 or the pipe from the reserve tank 12 to the cleaning nozzle 14 to heat the cleaning liquid. As a result, comfortable cleaning can be performed even in winter and the like.

In this example, SAN-TIWS manufactured by Takahashi Metal Co., Ltd. was used as the high-concentration hypochlorous acid water. In this high-concentration hypochlorous acid water, an aqueous sodium chloride solution to which hydrochloric acid for pH adjustment is appropriately added is passed through one electrolytic cell (for example, a cathode chamber) of a two-chamber electrolytic cell, and then the other electrolytic cell (for example, a cathode chamber) is passed. For example, it was obtained by passing water through an anode chamber). The high-concentration hypochlorous acid water may be obtained by electrolysis in a non-diabolic single-chamber electrolytic cell instead of the two-chamber electrolytic cell. Further, the high-concentration hypochlorous acid water may be a mixture of hypochlorous acid water obtained by electrolyzing an aqueous sodium chloride solution and a part of the hypochlorous acid water obtained during the electrolysis.

The cartridge tank 110 is composed of, for example, a pouch container containing 10 L of the Santius (pH 6.5, effective chlorine concentration: about 1800 mg / L). In this example, the flow rates of the pump 11 and the pump 12 were adjusted, and the high-concentration hypochlorite water was diluted with clean water about 40 times. The obtained diluted hypochlorous acid water had an effective chlorine concentration of about 50 ml / L at around pH 5.

The air supply means are arranged on the blower 21 that blows the outside air sucked through a large number of openings 401 provided on the side surface of the housing 40 through the duct 211 and on the upstream side (opening 401 side) of the blower 21. A purification filter 22 made of a HEPA filter and an air supply port 411 (vent) provided in the sink 41 through a connecting portion 23 and a duct 212 are provided.

The air supply port 411 is also arranged above the wall surface on both sides of the sink 41. Further, a plurality of blowers 21 are also provided corresponding to each air supply port 411, and it is possible to drain and dry the water in a short time with a sufficient air volume.

The ozone supply means includes an ozone generator 31 and a fan 32 that sends the ozone generated by the ozone generator 31 to the duct 212 on the downstream side of the blower 21 through the conduit 33 and the connecting portion 23. In this example, the amount of ozone generated by the ozone generator 31 was set to 4 mg / h.

《Operation》
The cleaning / drying device M, whose power is turned on by the microcomputer (not shown / control means) built in the control panel 50, operates as shown in FIG.

(1) When the power of the washing / drying device M is turned on, the ozone generator 31 and the fan 32 continuously operate to constantly supply ozone to the air supply port 411 (step S1).

When it is detected by the infrared sensor or the like (not shown) that the finger or the like to be cleaned is inserted into the sink 41 (step S2), the pumps 11 and 12 are operated (step S3). As a result, diluted hypochlorous acid water is ejected from the cleaning nozzle 14 to the fingers inserted into the sink 41, and the cleaning mode is started. Then, when the preset cleaning time elapses (step S4), the pumps 11 and 12 are stopped (step S5). The cleaning mode ends when the pump 11 is stopped. For example, the cleaning time (discharging time of the cleaning liquid) in the cleaning mode may be about 16 to 18 seconds, and the amount of the cleaning liquid ejected may be about 320 to 360 ml.

After confirming that the fingers have not been pulled out from the sink 41 (step S6), the blower 21 is operated (step S7). As a result, a drying mode is started in which the diluted hypochlorous acid water adhering to the fingers inserted in the sink 41 is drained and dried by the air blown from the air supply port 411. The blower 21 continuously operates as long as the fingers are in the sink 41 (step S8). However, the blower 21 is stopped (step S10) when the finger is pulled out from the sink 41 (step S8) or when a preset drying time (for example, 30 seconds) elapses (step S9). The drying mode ends when the blower 21 is stopped.

(2) When the state in which fingers or the like are not detected in the sink 41 elapses for a preset time (for example, 1 hour) (steps S2 and S11), the pumps 11 and 12 are operated to eject the cleaning liquid into the sink 41. (Step S12). When the preset cleaning time (for example, 5 seconds) has elapsed (step S13), the pumps 11 and 12 are stopped to stop the ejection of the cleaning liquid (step S14). Even when the cleaning mode and the drying mode are not performed in this way, the self-cleaning mode is periodically performed. The amount of the cleaning liquid ejected in the self-purification mode may be, for example, about 100 ml.

By the way, ozone is continuously supplied to the sink 41 even before the start of the self-purification mode. Therefore, the organic substances and the like adhering to the sink 41 are in a state of being oxidatively decomposed in advance by the ozone. As a result, the diluted hypochlorous acid water ejected in the self-purification mode acts directly on bacteria and the like without much water repellency in the sink 41. Therefore, the self-purification mode of this example exhibits a high sterilization effect.

(3) Even when not in the drying mode, ozone generated by the ozone generator 31 is supplied from the air supply port 411 by the fan 32. A part of the ozone is used for oxidative decomposition of organic substances and the like adhering to the sink 41 as described above, but most of the ozone is released to the installation space of the washing / drying device M. Therefore, at least the installation space in the vicinity where the washing / drying device M is set is also air-cleaned by the ozone.

As described above, the washing / drying device M according to the present embodiment can perform not only washing / sterilization / drying of fingers and the like, but also self-cleaning of the device itself and cleaning of the space in which the device is set.
