Description

Hand Sanitizer {A HAND CLEANER}

The present invention relates to a hand disinfecting apparatus, and more particularly, to a hand disinfecting apparatus capable of minimizing the loss of chemicals due to the leakage of residual disinfectant remaining in the nozzle after the operation of the hand disinfecting apparatus.

As is well known, the hands are always kept clean in places where clean hygiene is required, such as a restaurant for cooking food, a hospital, or a laboratory for processing chemicals.

For the hygiene of the hand, it is common to wash the hand directly with water or to wear a disposable sterilized gloves, etc., but it is difficult to expect a desirable effect in terms of hand hygiene and work efficiency.

For example, when cooking food in a restaurant, most cooks touch the food ingredients after washing their hands with water or washing their hands with sterilized dishcloth, etc.The cook keeps his hands clean by touching or moving other objects. It was not easy to do.

In addition, in the case of wearing disposable gloves, the work efficiency is not as good as that of performing work with bare hands, and these disposable gloves are generally disposed of once discontinued, so waste of resources and secondary environmental pollution, etc. There was a problem such as causing.

For the hygienic aspect of the hand and to solve various inconveniences, a hand disinfection device that can disinfect hands more recently has been widely used.

The hand disinfection device detects a hand through a sensor, operates a pump to transfer the disinfectant stored in the disinfectant storage tank to the nozzle at a constant pressure, and disinfects the hand while the disinfectant is directly injected into the hand through the nozzle. It is meant to be built.

However, in the conventional hand sanitizer as described above, once the pump stops operating, the pressure formed in the conduit leading to the nozzle is discharged to the outside through the nozzle, so that the residual disinfectant solution remaining in the nozzle is discharged from the nozzle. There was a problem that caused the loss of the drug.

Then, the residual disinfectant solution leaked to the outside through the nozzle as described above had a problem that eventually fall to the floor to contaminate the environment around the floor.

Thus, the present invention is devised to solve the above problems, the purpose of the present invention is to provide a hand sanitizing device that can prevent the loss of disinfectant due to leakage of the residual disinfectant remaining in the nozzle after hand disinfection is completed.

In addition, the case 100 is further provided with a blower fan 170 for controlling the hand and drying the hand and a lamp 180 for visually confirming the disinfection process of the hand.

FIG. 3 is a view schematically showing the main components of the hand sanitizing apparatus 200 shown in FIG. 2 and the flow of the disinfectant solution in the conduit.

2 and 3, the present invention will be described in more detail. The sensor 160 provided in the case 100 is electrically connected to the controller 150, and detects a hand signal. It is output to the control unit 150.

On the other hand, the case 100, the disinfectant solution reservoir 110 for the storage of the disinfectant solution 114 is installed.

A disinfectant solution inlet 112 is formed on the upper surface of the disinfectant storage container 110 to enable disinfectant solution injection from the outside in a state where the lid 104 of the case 100 is opened.

And, one side of the bottom surface of the disinfectant reservoir 110 is connected to the pump 130 for the transfer of the disinfectant solution 114, the pump 130 is electrically connected to the control unit 150 and the control unit 150 Controlled through

Such a pump 130 pumps the disinfectant solution 114 stored in the disinfectant reservoir 110 at a constant pressure (about 8 kgf / cm 2) during operation to disinfect the solution 114 for a predetermined time through the nozzle 120 to be described later. Spray it.

In addition, the pump 130 is set to continuously operate during the time that the sensor 160 detects the object.

Here, the present invention generally employs an electromagnetic pump that is operated by an electrical signal and can transport the fluid at a pressure generated by applying a magnetic field to the fluid to flow a current.

However, of course, other usable pumps may be employed in addition to the electronic pump.

On the other hand, the nozzle 120 is connected to the pump 130 to inject the disinfectant solution pumped by the pump 130 to a predetermined pressure to the outside of the case 100.

At this time, the disinfectant solution sprayed to the outside of the case 100 through the nozzle 120 is sprayed in the form of fine particles of about 10㎛.

On the other hand, on the pipe line connecting the nozzle 120 and the pump 130, a fitting pipe 124 having a T shape is installed at a position close to the nozzle 120.

That is, two of the three inlets of the fitting pipe 124 are respectively connected to the nozzle 120 and the pump 130 side, the other one inlet is connected to the solenoid valve 140 side to be described later It is.

The solenoid valve 140 is electrically connected to the control unit 150 and controlled through the control unit 150, and one end of the nozzle 120 and the pump 130 through the T-shaped fitting pipe 124. Is connected to the pipe to connect, the other end is connected to the bottom portion of the disinfectant reservoir 110.

Here, a separate check valve on the pipe connecting the solenoid valve 140 and the disinfectant reservoir 110 to prevent the disinfectant stored in the disinfectant reservoir 110 is introduced into the solenoid valve 140 side ( 142 is provided.

The check valve 142 prevents the disinfectant stored in the disinfectant reservoir 110 from flowing into the solenoid valve 140, while the flow of the disinfectant solution from the solenoid valve 140 toward the disinfectant reservoir 110. Is allowed.

The solenoid valve 140 is configured to close the internal pipe when the pump 130 is operated normally, and is operated when the pump 130 is stopped to open the internal pipe for a predetermined time (about 3 seconds). It is set to ever.

On the other hand, as shown in Figure 2, the lower portion of the disinfectant reservoir 110 is provided with a blowing fan 170 to face the opening of the bottom surface of the case 100.

The blowing fan 170 is electrically connected to the control unit 150 and controlled by the control unit 150, and starts driving from a section of about 70% of the total operating time of the pump 130. 5 to 15 seconds).

Therefore, the blowing fan 170 is operated after the disinfection process of the hand is completed by spraying the disinfectant solution through the nozzle 120 to generate air pressure to circulate the hand to achieve the drying operation of the hand.

In this case, the blower fan 170 may be provided with a separate air heating means such as a heater to increase the drying efficiency during the hand drying process.

In the above-described operating structure, the blowing fan 170 is directly connected to the control unit 150 to operate through the control unit 150. Alternatively, the blowing fan 170 may be driven by using a separate button means. .

That is, by installing an operation switch (not shown) which can turn on / off the blower fan 170 at a proper position on the outer surface of the case 100 of the hand sanitizing device 200, the operation switch is turned on according to the user's needs ( It is configured to control the driving of the blowing fan 170 by turning ON or OFF.

This allows the blower fan 170 to be selectively operated whenever the user needs it, thereby providing its utility when no separate drying operation is required.

On the other hand, the lamp 180 is installed in the case 100. The lamp 180 provides convenience for the user to visually check the disinfection process during the hand disinfection process.

The lamp 180 is electrically connected to the control unit 150 and controlled through the control unit 150, and lights together when the pump 130 is operated, and blinks when the pump 130 is stopped.

In an embodiment of the present invention, the operating time of the lamp 180 is set to be the same as the operating time of the pump 130, but the operating time of the lamp 180 until the operation of the blower fan 170 is completed. You can also set it to light.

On the other hand, the hand sanitizing device of the present invention is configured so that the pump 130 is continuously operated while the hand is being sensed through the sensor 160, so that the disinfectant solution can be continuously sprayed, unlike the above, the spraying of the disinfectant solution It is also possible to make the process proceed only for a fixed time.

This can be achieved through the controller 150 in which the disinfectant dispensing time is programmed and set. For example, when the disinfectant dispensing time of the nozzle 120 is set to 5 seconds, the pump 130 and the lamp 180 are operated. 5 seconds, 70% of the total operating time of the blowing fan 170 is operated to operate continuously for about 15 seconds, the solenoid valve 140 is the pump 130 It is opened from the time when the operation stops and keeps opening for about 3 seconds.

On the other hand, if the disinfectant spray time of the nozzle 120 is set to 10 seconds, the operating time of the pump 130 and the lamp 180 to 10 seconds, 70% of their total operating time of the blower fan ( 170 is operated to operate continuously for about 15 seconds, the solenoid valve 140 is opened from the time when the operation of the pump 130 is stopped to maintain the open state for about 3 seconds.

As such, when the spraying time of the disinfecting liquid is set in units of a predetermined time, each operation time of the pump 130, the solenoid valve 140, the blowing fan 170, and the lamp 180 is automatically adjusted to match the disinfecting liquid spraying time. By setting, the user can set and use the disinfectant spraying time properly as needed.

Hereinafter, the operation and effects of the present invention described above will be described in detail with reference to FIGS. 2 and 3.

First, when the user approaches the hand under the hand disinfection device 200 for hand disinfection, the sensor 160 detects a hand and outputs a signal to the controller 150, and the controller 150 pumps ( 130 is driven and the lamp 180 is turned on at the same time.

Accordingly, as shown in FIG. 3, the pump 130 pumps the disinfectant solution 114 stored in the disinfectant reservoir 110 at a predetermined pressure to forcibly transfer the nozzle 120 to the nozzle 120, and the nozzle 120. In the), disinfecting process is performed by spraying disinfectant solution on the hands in the form of fine particles.

At this time, during the hand disinfection process, since the lamp 180 is continuously kept lit, the user can continuously check the cleanliness of the hand while observing his hand disinfection process with his eyes.

In particular, it is expected that the better effect can be achieved during night time, which is relatively difficult to secure the view.

Thereafter, when the user goes through the hand disinfection process for a certain time, when the hand is disinfected in the hand sanitizing device, the detection sensor 160 detects this and stops the operation of the pump 130. Disinfection of the disinfectant through 120 is stopped.

At this time, the controller 150 opens the solenoid valve 140 by applying an electrical signal to the solenoid valve 140 at the same time as the operation of the pump 130 is stopped.

As the solenoid valve 140 is opened, a flow of disinfectant is formed along a new pipe leading to the pump 130, the solenoid valve 140, and the disinfectant reservoir 110.

At this time, in the solenoid valve 140, a pressure difference due to the difference between the diameter of the tip of the nozzle 120 and the diameter of the orifice in the solenoid valve 140 is formed, so that the disinfectant solution in the pipeline is rapidly disinfected solution. It moves toward the reservoir 110.

In addition, in the joint pipe 124, the residual disinfectant solution remaining in the nozzle 120 without being injected to the outside due to a rapid pressure drop due to an increase in the speed of the fluid toward the solenoid valve 140 through the joint pipe 120. Is returned.

Thereafter, when a predetermined time passes, the solenoid valve 140 is closed through the controller 150 to prevent backflow of the disinfectant solution flowing into the solenoid valve 140.

When the above-described hand disinfection process is completed, the controller 150 operates the blower fan 170 to release air pressure through the opening of the bottom surface of the case 100 to dry the hand.

On the other hand, in one embodiment of the present invention as described above, but the check valve 142 on the conduit connecting the disinfectant reservoir 110 and the solenoid valve 140 is configured to block the back flow of the disinfectant, but the check The same effect can also be obtained without employing the valve 142.

4 is a view showing another embodiment of the present invention. Here, the same configuration as that of the first embodiment and the connection structure thereof will not be described.

4, in the second embodiment of the present invention, the connection structure between the solenoid valve 140 and the disinfectant reservoir 110 is different.

That is, one end of the solenoid valve 140 is connected to the upper surface of the disinfectant reservoir 110, the other end is connected between the pipe connecting the nozzle 120 from the pump 130 as in the first embodiment Other than this, it has the same structure as in the first embodiment.

The connection structure as described above is because the conduit from the disinfectant reservoir 110 to the solenoid valve 140 is not directly in contact with the disinfectant 114 in the disinfectant reservoir 110, so that Impact can be ruled out.

In other words, since the disinfectant solution 114 cannot be introduced into the solenoid valve 140 when the solenoid valve 140 is opened, a check valve used as a backflow prevention means of the disinfectant solution is required unlike the first embodiment described above. There will be no.

As described above, when the connection structure between the solenoid valve 140 and the disinfectant reservoir 110 is appropriately changed, even if one component such as a check valve is excluded, the same operation as in the first embodiment of the present invention is achieved. You will get the effect.

According to the present invention described above, when the pump is stopped, the solenoid valve is opened so that the residual disinfectant remaining in the nozzle can be returned to the disinfectant storage container due to the pressure drop due to the increase in the speed of the disinfectant flowing through the pipe. It is possible to prevent the loss of disinfectant solution.

In addition, since the disinfectant solution left in the hand can be evaporated by using a blower fan, the hand drying process following the hand disinfection process can be completed in a series of processes.

In addition, since the lamp is always kept on when the disinfectant is sprayed through the nozzle, the user can easily check the cleanliness of the hand while visually checking his or her hand disinfection process, especially during dark night hours. When used, the effect can be doubled.

In addition, by installing a check valve on the conduit connecting the disinfectant reservoir and the solenoid valve, it is possible to prevent the disinfectant stored in the disinfectant reservoir to flow into the solenoid valve side.
