Description

[Technical Field]

[0001] The present invention relates to a cleaning device for cleaning hands and fingers. [Background technology]

[0002] A cleaning device that circulates water for repeated use can be used, for example, for hand washing at construction sites. Patent Document 1, for example, is a reference for this type of device. The device in this document is equipped with a reverse osmosis membrane water purification unit or the like midway through the circulation, which purifies the water and allows it to be used repeatedly.

[0003] However, the device described in the literature has a low water flow rate of approximately 1–2 L / min, making it unsuitable for some construction sites. For example, in construction sites for high-rise apartment buildings and skyscrapers, workers of many different trades work, with dozens to hundreds of workers sweating on a single floor. Despite this, the site lacks water supply and drainage infrastructure, so hand washing currently relies on wet towels and wet tissues. While it would be desirable to use the device described in the literature, the low flow rate makes it unsuitable. The device described in the literature is intended for use by a few workers in remote mountain areas, which is likely why it is said to be capable of being used as drinking water.

[0010] [Effects of the Invention]

[0011] According to the present invention, a cleaning device with a high flow rate is provided. [Brief explanation of the drawings]

[0012] [Figure 1] 1 is a system diagram of a cleaning device according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0013] Next, an embodiment of the present invention will be described. Note that this embodiment is an example of the present invention. The scope of the present invention is not limited to the scope of this embodiment.

[0014] (Application) The cleaning device of this embodiment circulates cleaning liquid, allowing the cleaning liquid to be reused, but is not intended for use as drinking water. In other words, it is intended for use in hand-washing and other applications during construction work on high-rise apartment buildings and skyscrapers. Of course, it can also be used to wash oil stains on tools and other items, but it is usually preferable to use a device that is specialized for hand-washing and is equipped with a purification means suitable for hand-washing applications, for example, in order to maximize the flow rate.

[0015] (Cleaning equipment) FIG. 1 shows a system diagram of the cleaning device X of this embodiment. The cleaning device X uses alkaline water with a pH of 8.5 to 12.5 as the cleaning solution W, preferably alkaline water with a pH of 8.5 to 11.5, and more preferably alkaline water with a pH of 8.5 to 9.5. The use of alkaline water, due to its sterilizing properties, shortens the processing time of the purifying means, particularly the sterilizing means such as an ultraviolet irradiation device, and increases the flow rate of the cleaning device X. Furthermore, the purifying means can be made more compact, making the cleaning device X more portable. Furthermore, the use of alkaline water eliminates the need for cleaning agents such as soap, thereby shortening the device usage time per person and enabling more workers to use the device. In this regard, for example, if the outlet 11 (described below) is equipped with a touchless sensor that starts and automatically stops the water flow without touching, the usage time per person can be reduced, thereby achieving the original purpose of increasing the flow rate, i.e., allowing more workers to use the device.

[0016] The cleaning device X of this embodiment is composed of an outlet 11 for cleaning liquid W, a receiving tray 12 that receives the cleaning liquid W from the outlet 11, a filtering means 20 that filters the cleaning liquid W from the receiving tray 12, a storage tank 30 that stores the cleaning liquid W from the filtering means 20, a sterilizing means 40 that sterilizes the cleaning liquid W from the storage tank 30, and a flow path R1 that guides the sterilized cleaning liquid W to the outlet 11. The filtering means 20 and the sterilizing means 40 form a purification means.

[0017] The outlet 11 is the location from which the cleaning liquid W is sprayed, and is preferably equipped with a touchless sensor or the like that automatically dispenses the cleaning liquid W when a hand is placed over it, as described above. There may be one outlet 11, but preferably there are two or more outlets. Because the cleaning device X of this embodiment has a high flow rate, multiple outlets can be installed.

[0018] After the cleaning liquid W from the outlet 11 has been used for washing a person's hands or fingers, it is received in the receiving tray 12. The receiving tray 12 is in the form of a container with an open top, and is constituted by, for example, a sink.

[0019] The cleaning liquid W received in the receiving tray 12 is sent to the filtering means 20 through a flow path R2 having a filtering pump 23 provided therein.

[0020] The filtering means 20 is preferably composed of a cylindrical filter 21 and an adsorbent 22 attached to the upstream side of the filter 21. The filter 21 is preferably folded in a pleated shape, and in detail, the filter 21 described in JP 2021-016826 A proposed by the present applicant can be used.

[0021] On the other hand, the adsorbent 22 is attached to the upstream side (the side closer to the tray 12) of the filter 21. As the adsorbent 22, for example, activated carbon, zeolite, diatomaceous earth, or the like can be used.

[0022] Such adsorbent-attached filter-type filtering means has already been commercially available, for example, as an LFP filter.

[0023] The cleaning liquid W (filtrate) filtered by the filtering means 20 is sent through a flow path R4 to the storage tank 30 and stored therein. The storage tank 30 is provided with a level sensor as needed to detect whether the tank is full or whether water needs to be added.

[0024] The cleaning liquid W stored in the storage tank 20 is sent to the sterilization means, in this embodiment, the ultraviolet irradiation means 40, through the flow path R5 equipped with the water supply pump 31, and is sterilized. The time for this sterilization is preferably 0.5 to 2 seconds, more preferably 1.5 to 2 seconds. If the sterilization time is too short, sufficient sterilization cannot be achieved, but in this embodiment, alkaline water is used as the cleaning liquid W, so sufficient sterilization can be achieved within the above-mentioned time. However, if the sterilization time is too long, the circulation speed of the cleaning liquid W becomes too slow, making it impossible to ensure a sufficient flow rate, so the sterilization time is preferably within the above-mentioned time.

[0025] The cleaning liquid W sterilized in the ultraviolet irradiation means 40 is returned through the flow path R1 to the liquid outlet 11. As can be understood from the above, the purification device X of this embodiment can function even without infrastructure for water supply and drainage.

[0026] (preparation) To use the cleaning device X of this embodiment, the power outlet is plugged in and the power is turned on as needed. Then, the filtration pump 23 is turned on to supply water to the receiving tray 12. This water may be prepared in advance, or the receiving tray 12 may be configured to receive rainwater, i.e., rainwater may be used. The amount of water supplied may be limited, for example, by supplying a predetermined amount of water, or a level sensor attached to the storage tank 30 may detect a full water level, and this detection result may be recognized in an appropriate manner to guide the supply to stop. The filtration pump 23 may be temporarily turned off as needed.

[0027] Next, the filtration pump 23 is turned on again to supply alkaline ionized water to the tray 12. As this alkaline water, for example, potassium electrolyzed water or the like can be used.

[0028] Furthermore, the adsorbent slurry is supplied to the tray 12. This supply causes the adsorbent 22 to adhere to the filter 21 of the filtration device 20. With this, the purification device X is ready for use.

[0029] (others) The cleaning liquid W is forced into the filtering device 20 by the operation of the filtering pump 23. This pushing pressure is detected by a pressure gauge 24, and it is preferable to configure the device so that if the pressure suddenly rises, a warning is issued or the device is stopped immediately.

[0030] It is preferable that the level sensor of the storage tank 30 detects not only when the tank is full of water but also when there is a shortage of the cleaning liquid W. This detection makes it possible to know when to supply water or alkaline water.

[0031] When regenerating the adsorbent 22 or replacing the cleaning liquid W, the drainage flow path (drainage line) R3 provided on the path from the receiver 12 to the filtration means 20 is opened by switching the switch valve 25, and the old adsorbent 22 and cleaning liquid W are discharged outside the system through this flow path R3. This configuration eliminates the need for work such as dismantling the device, and can be performed by workers themselves, making maintenance extremely easy. The supply of cleaning liquid W and adsorbent 22 is the same as in the preparation of the cleaning device X.

[0032] The cleaning device X of this embodiment is preferably a portable type that can be carried in by an elevator or the like, and may have wheels or the like, or may be of a type that can be moved by a dolly or the like with a handle. [Industrial Applicability]

[0033] The present invention can be used as a washing device for hands and fingers. [Explanation of symbols]
