Description
Technical field
The present invention relates to the field be used to the device of washing one's hands, particularly washing and dry hand in bathhouse.
Background technology
Wash one's hands and often be counted as health, and proved a kind of effective means that prevents some kinds of transmissions.
Investigation shows that people always do not wash one's hands in bathhouse (being also referred to as the lobby).Do not wish to be bound by theory, it has been generally acknowledged that bathhouse itself is antihygienic, so the user contacts any article of bathhouse inside would rather not, and wish to leave as early as possible bathhouse.
For many years, attempted multiple mode make in bathhouse, wash one's hands more attractive.
Recent decades, electric drying apparatus is used to dry hand after washing, to avoid the napkin dispenser with dirty towel and possibility cut-off.
Soap dispenser has replaced soap bar, and automatic faucet has solved the problem that contacts addle tap knob after washing for pass water.
US 3918987 A (Kooper, Rudolph J.) disclose a kind of hand and forearm cleaning device, and it comprises that inwardly spraying fluid with set rate and pressure flows in order to carry out a plurality of nozzles of washing procedure.Though this device discloses for the total solution of washing one's hands, it is unresolved conserve water and the minimum problem of operating of use also.
All these solutions are unusual trouble and consuming time and take up room still.In addition, though these development have improved the common custom of washing one's hands, the total solution that is used for the less water of consumption of washing, sterilization and dry hand remains needs.
Therefore, the purpose of this invention is to provide a kind of device.
Another purpose provides a kind of device for wetting hand, deposition clean and/or sanitizing composition and continuous flushing.
Another purpose provides a kind of also device of dry hand after washing.
Another purpose is to use a spot of water during washing.
It is shocking that have been found that the air-water jet nozzle assembly that comprises two nozzles can be used to use a spot of water to clean hand at short notice, wherein first nozzle is communicated with the feed liquid source fluid, second nozzle is connected to compressed air source.
Summary of the invention

Fig. 2 illustrates the figure of air-water jet nozzle.
The specific embodiment
The invention provides a kind of be used to the device of washing one's hands.Can also be applicable to dry hand according to device of the present invention.This device is particularly suitable for using in bathhouse, for example bathroom, airport, gas station bathroom, office bathroom, hospital bathroom etc.Also can be susceptible to the device in domestic. applications.
According to the inventive system comprises the chamber, this chamber comprises: the opening that is used for inserting at least one hand; And air-water jet nozzle assembly, it comprises two nozzles, wherein first nozzle is communicated with the feed liquid source fluid; And second nozzle is connected to compressed-air actuated source.
The chamber
The chamber comprises for inserting hand so that the opening that use device cleans.The chamber can comprise alternatively for a more than opening that inserts two or more hands simultaneously, perhaps is used for the big opening of identical purpose.
Opening can be at any end place of chamber.The only side that is used for opening be sentence at the top for vertically insert hand or therein place, a side be used for that level is inserted or Anywhere between the two.The opening that is used for inserting hand at bottom place is not excluded outside the scope in the application, but is not that the expection user is preferred usually.
The chamber also comprises air-water jet nozzle assembly, and it comprises two nozzles, and one is used for air, and one is used for liquid.Preferably, the chamber can comprise a more than air-water jet assembly, even more preferably, this device comprises the array of air-water jet nozzle, and these nozzles cover the whole surface of hand simultaneously, a side at least one times, but preferred both sides.
Air-water jet assembly
Air-water jet assembly comprises two nozzles, and wherein first nozzle is communicated with the feed liquid source fluid, and second nozzle is connected to compressed-air actuated source.Air-water jet device is incorporated in the hand washing device.
Fluid supply can be any water source, perhaps by pump, by holding water pressure vessel or by any other means or even directly provide to air-water jet device from water main by gravity (that is, by more than the use height that reservoir of water is placed air-water jet).
Feed liquid can be any liquid.Clean for conventional skin, it is preferred that Aquo-composition is generally.The nozzle that is used for liquid is called as (operating) water nozzle hereinafter, but should be appreciated that (operating) water nozzle can flow through water or any other liquid, comprises liquid, aqueous and comprises other composition for processing skin of beneficiating ingredient alternatively.
Similarly, the air source can be any air source, perhaps by separating with hand washing device or placing the compressor in the hand washing device or provide by compressed-air line (for example common in hospital).
Preferably air can be heated.Preferably, air themperature is at least 30 ° of C, more preferably at least 35 ° of C, at least 40 ° of C more preferably also, but usually less than 70 ° of C, more preferably less than 65 ° of C or even less than 60 ° of C.
First nozzle ((operating) water nozzle) and second nozzle (air nozzle) are all located with respect to imaginary central axis line (NOR).First nozzle be positioned to respect to central axis become between 1 and 60 °, the angle between 10 ° and 30 ° (α) preferably; And second nozzle with respect to central axis become between 1 and 45 °, the angle between 15 ° and 30 ° (φ) preferably.

To prove the present invention by means of following limiting examples now.
Example 1: hand cleaning
In this example, will compare with the conventional hand cleaning that utilizes identical cleaning formulation by means of device adversary's according to the present invention cleaning.
Preliminary treatment
Before test, the alcohol with 70% carries out decontamination to the hand of example and comparative example, so that from removing normal flora on hand, and allows dry and with the alcohol of sterile distilled water removal trace.
Then, will comprise 10
7100 microlitre solution of individual non-pathogenic coli strain cell (in 100 microlitres) are coated to every on hand, and require the volunteer that culture is smeared out at palm and finger.
A hand (example 1) ethoxylated alcohol nonionic surfactant (C of the 3g/L of 10ml
＜12 〉E0
＜7 〉, non-ionic surface active agent) to wash 15 seconds, another hand (Comparative examples A) uses air-water jet device according to the present invention to wash 15 seconds with the surfactant of same amount.
Air-water ejector comprises two nozzle assemblies in example; The air pressure of air-water jet device is 4 bar, and the fluid flow of each nozzle assembly is 20ml/min.
For security reasons in sealed chamber, carry out according to of the present invention washing one's hands.
With conventional method measurement remaining bacteria on hand.
The result
Wash result with regard to remaining bacterium colony (representing with the CFU/ hand) provides in following table.
The result
| ? | Example 1 | Comparative examples A |
| The log CFU/ hand of coating | 7 | 7 |
| Remaining log CFU/ hand | 4.2 | 3.6 |
Can know from last table and to find out that the washing methods that utilizes air-water jet device the Escherichia coli of removing about 0.6 log than conventional washing methods more.
