Description

Dust suction mat with sterilization function}

The present invention relates to a dust suction mat, and more specifically, to a dust suction mat, which is installed at the entrance of a building, etc., and sucks dust stuck to the soles of the shoes of visitors using a vacuum method, and at the same time sprays a disinfectant solution on the place where the people stand, removing harmful substances stuck to the shoes. It is about a dust suction mat that has a sterilizing function that can even remove germs.

Recently, fine dust in the air has emerged as a serious social problem. When people inhale air pollutants emitted from factories or automobiles, it not only causes various respiratory diseases, but in severe cases, it can even lead to death.

In addition, since the atmosphere circulates globally, the efforts of only one country cannot completely solve the country's fine dust problem. Therefore, there is an urgent need for joint research and cooperation between countries to reduce fine dust. .

Accordingly, each country is carrying out many policy efforts and research to reduce fine dust in the air, but it is true that there has been relatively little attention to indoor fine dust, which is actually more serious than fine dust in the air.

In addition, until now, the problem of indoor fine dust has been focused only on removing dust that has already entered the room after the fact using air purifiers, and there has been great interest in fundamentally blocking or reducing the inflow of fine dust indoors. It is also true that I did not have it.

Recently, as a way to block or reduce the inflow of fine dust entering the room, dust suction mats are known to be installed at entrances to buildings, etc., and suck in dust from the soles of visitors' shoes like a vacuum cleaner.

However, such dust suction mats have the limitation that they only remove dust from the bottom of shoes and do not have a sterilizing function, and the part that suctions dust is composed of a simple hole shape, so the entrance of the hole (dust hole) is exposed to dirt or foreign substances. If it gets clogged, there is a problem that dust cannot be removed properly.

This not only removes dust from the soles of visitors' shoes, but also removes germs that may attach to the soles of shoes and enter the room. Even if the entrance to the dust intake area (dust hole) is blocked by dirt or foreign substances, good dust removal is possible. There is a need for a dust suction device that provides removal performance.

It can even remove germs that may stick and enter the room, thereby creating a more comfortable and safe indoor environment.

In addition, due to the unique configuration of the through hole (a configuration in which a plurality of grooves are formed radially around the through hole) through which dust is actually sucked in when a person steps on the top, the area that can absorb dust is increased without increasing the size of the through hole. By being able to expand, it is possible to minimize dead zones and remove dust more evenly across the entire sole of the shoe.

In addition, due to the unique configuration of the through hole (a configuration in which a plurality of grooves are formed radially around the through hole), even if the entrance to the through hole, which is the main suction passage, or part of the groove including the entrance is blocked by dirt or foreign substances, the entire through hole is blocked. As long as it is not blocked, dust can be sucked in through other nearby unblocked grooves, so dust removal performance can be maintained at a good level.

At this time, the groove 118 may be formed in a cross (+) shape based on the through hole 117 as shown in the drawing, but is not limited thereto.

This through-hole part will be examined in more detail later with reference to FIGS. 5 and 6.

Meanwhile, the disinfection and sterilization unit 120 includes a second enclosure 122 whose internal space is opened or closed by the cover 124. Inside the second enclosure 122, a disinfection container 126 containing a disinfectant solution is installed, and a detection sensor 127 detects the approach of an intruder and a dust suction unit 110 based on the detection signal of the detection sensor 127. A disinfectant spray port 128 that sprays disinfectant toward may be installed on one side of the second enclosure 122 (the side facing the dust intake unit).

The disinfection and sterilization unit 120 may further include an ultraviolet irradiator 129 that irradiates ultraviolet rays with a strong sterilizing effect. The ultraviolet irradiator 129, like the detection sensor 127 and the disinfectant nozzle 128, may be installed on one side of the second enclosure 122 (the side facing the dust suction part), and the entry and exit of the detection sensor 127 Ultraviolet rays may be irradiated toward the dust intake unit 110 under the control of a control unit (not shown) based on a detection signal.

And the dust collection container 121 is connected to one side of the passage inside the first enclosure 112 through a pipe or hose to primarily collect dust in the air flowing in from the first enclosure 112.

Figure 5 is an enlarged perspective view of the main part of the present invention showing a part of the dust suction part shown in Figure 4, and Figure 6 is an enlarged perspective view showing the through hole formed in the upper plate. And Figure 7 is an enlarged cross-sectional view of the main part of the present invention to show the coupling relationship between the through hole and the through hole opening and closing means.

Referring to FIGS. 5 to 7, each of the plurality of through holes 116 formed in the upper plate 114 includes a through hole 117 having a circular planar shape and a circumference of the through hole 117, as previously mentioned. It may be composed of at least two grooves 118 formed radially to be connected to the through hole 117. Here, each groove 118 may be inclined downward in the direction of the through hole 117.

That is, the depth of the groove 118 is lower the farther it is from the through hole 117, and the deeper it is, the closer it is to the through hole 117, so that it meets the through hole 117 below the uppermost entrance of the through hole 117. You can. At this time, the groove 118 may be formed in a ten (+) shape based on the through hole 117, and its cross-sectional shape is not limited to the ∪ shape shown and may have various changes such as an arch shape or ∨ shape.

According to the configuration of the through hole 116 of the present invention, the size of the through hole is maintained at a size capable of generating an appropriate suction force, and the through hole is simply formed in the shape of a hole to collect dust in only one direction (vertical direction). Unlike conventional configurations that suck dust, dust can be sucked in from multiple directions. As a result, the dead zone, where dust cannot be properly removed due to lack of suction power, is greatly reduced.

In addition, since the through hole is composed of a plurality of grooves formed radially around one through hole, even if the entrance of the through hole, which is the main suction passage, or a part of the groove including the entrance is blocked by dirt or foreign substances, the entire through hole is blocked. As long as the groove is not blocked, dust can be sucked in through other unblocked grooves, so dust removal performance can be maintained at a good level.

The opening opening and closing means 130 may be a ball plunger composed of a ball 132 and a spring 134. The balls 132 are disposed in the lower part of the upper plate 114 so as to correspond one by one to the through holes 116 formed in the upper plate 114, and the spring 134 is located at the lower part of each ball 132 so that the balls 132 It comes in close contact with the lower end of the corresponding through hole 116 and provides a restoring force to close the through hole 116. This spring 134 may be, for example, a compression coil spring.

Preferably, the ball 132 partially protrudes above the through hole 117 and is located higher than the upper surface of the upper plate 114, and is larger than the diameter of the through hole 117 to prevent it from coming out through the through hole 117. Can be formed in large diameters.

A spring supporter 136 may be installed on the inner bottom surface of the first enclosure 112 so that the spring 134 can stably support the ball 132 without being separated from under the through hole 116. . For example, the spring support member 136 may be a rod-shaped structure that protrudes from the bottom surface at a lower height than the spring 134 and is inserted into the inside of the spring 134, as shown in the drawings (FIGS. 5 and 7). It is not limited to this.

Figure 8 is a perspective view from another angle (opposite the dust suction part) with a sterilizing function according to an embodiment of the present invention.

As shown in FIG. 8, a timer 123 may be installed in the second enclosure 122. The timer 123 may include a disinfectant spray timer 123a and a dust suction mat operation timer 123b. The disinfectant spray timer 123 may display the time at which the disinfectant is sprayed, and the dust suction mat operation timer 123 may display the time at which the suction force generating means (M) operates to suction dust.

The timer 123 may be equipped with a setting button (not shown) for setting the time for which the disinfectant is sprayed and the time for the motor to operate for dust suction. It can be operated by the power applied at the time the detection signal is output. At this time, when the timer 123 reaches the set time, the control unit can detect this and stop the disinfectant spraying and dust suction operations.

In Figure 8, reference numeral S1 is a power switch that turns on/off the supply of power for the operation of the dust suction mat according to an embodiment of the present invention, and reference numeral S2, expressed in the form of a small switch next to the power switch, is a disinfectant spray switch. This is a switch to turn on/off the disinfectant spray function. Here, when the disinfectant spray switch is in the off state, only the dust suction unit 110 can be operated without spraying the disinfectant.

And reference numeral 125 indicates a HEPA filter installed to filter out fine dust not collected in the dust collection container 121.

Hereinafter, we will look at the dust removal and shoe sterilization functions performed by the dust suction mat with a sterilization function according to an embodiment of the present invention configured as described above.

Figure 9 is a cross-sectional view showing the operating state of a dust suction mat with a sterilizing function according to an embodiment of the present invention. For convenience of explanation, the configurations shown in the preceding drawings will be described by referring to the corresponding reference numbers.

Referring to FIG. 9, when a person approaches a dust suction mat with a sterilizing function according to an embodiment of the present invention, the detection sensor 127 confirms the person's approach and transmits a signal to the control unit. The control unit that receives the signal from the detection sensor 127 first applies an operation command to the disinfectant extraction means (P) at the time the detection signal is input, which causes the dust suction unit 110 to be removed through the disinfectant nozzle 128. A disinfectant solution is sprayed on the top plate 114.

Here, the position of the disinfectant spray hole 128 formed on one side of the second enclosure 122 is not particularly limited, but is formed at a position where it can be sprayed toward the center area of the upper plate 114 of the dust intake unit 110. It is desirable.

In addition to controlling the disinfection spray at the point when the detection sensor 127 detects the approach of the person entering, the control unit uses an ultraviolet ray irradiator installed in the second enclosure 122 to irradiate ultraviolet rays toward the upper plate 114 of the dust suction unit 110. Authorize the operation command to (129). Here, the timing of applying the operation command to the ultraviolet irradiator 129 may be the same as or have a slight time difference from the timing of applying the operation command to the disinfectant solution extraction means (P).

When the person entering stands on the upper plate 114 of the dust suction part 110 where the disinfectant solution is sprayed, the opening opening and closing means 130, which was closing the through hole 117 with a portion exposed above the upper plate 114, is affected by the weight of the entering person. It is pressed down and falls into the inside of the first housing 112, thereby opening the through hole 117. Then, external air is sucked in through the open hole 117 by driving the suction force generating means (M).

In the process of sucking in external air through the hole 117, the dirt attached to the bottom of the shoe is sucked into the first enclosure 112 and removed, and the sucked dust is removed through the internal flow path of the first enclosure 112. It is first collected in the dust collection container 121 placed inside the second enclosure 122, and the fine dust that passes through the dust collection container 121 is finally filtered by the HEPA filter 125, so that only clean air is released to the outside. It is discharged as

Meanwhile, during the above dust removal process through the through hole 117, the entrance of the through hole 117 may be blocked by dirt or foreign substances, as shown in FIG. 10. In this case, dust is removed through the unblocked surrounding groove 118. It can be inhaled (see directions d1 to d4 in Figure 10).

That is, unless the through hole 117 and the surrounding groove 118 are blocked at the same time, dust is sucked in through the other unblocked groove 118, so dust removal performance can be maintained well.

According to the dust suction mat with a sterilizing function according to an embodiment of the present invention, a strong sterilizing function through ultraviolet ray irradiation and spraying of a disinfectant solution is provided along with a dust suction function, so that it not only removes dust from the bottom of the shoes of the person entering the room, but also removes dust from the bottom of the shoe. It can even remove germs that may stick and enter the room, thereby creating a more comfortable and safe indoor environment.

In addition, due to the unique configuration of the through hole (a configuration in which a plurality of grooves are formed radially around the through hole) through which dust is actually sucked in when a person steps on the top, the area that can absorb dust is increased without increasing the size of the through hole. By being able to expand, it is possible to minimize dead zones and remove dust more evenly across the entire sole of the shoe.

In addition, due to the unique configuration of the through hole (a configuration in which a plurality of grooves are formed radially around the through hole), even if the entrance to the through hole, which is the main suction passage, or part of the groove including the entrance is blocked by dirt or foreign substances, the entire through hole is blocked. As long as it is not blocked, dust can be sucked in through other nearby unblocked grooves, so dust removal performance can be maintained at a good level.

Figure 11 is a schematic cross-sectional view showing another preferred embodiment of the present invention. The dust suction mat 100 with a sterilizing function according to an embodiment of the present invention may further include a vibration generator 140. The vibration generator 140 may be mounted inside the first enclosure 112, and the first enclosure 112 is operated according to a command from the control unit to remove dirt or foreign substances adhering to the upper panel 114 from the upper panel 114. Vibrate up and down.

The vibration generator 140 can be driven by turning on a cleaning mode switch (not shown) that can be placed in the second enclosure 122, and when the switch is turned on, the vibration generator 140 and the suction force generating means (M ) are operated together, so that dust fallen from the upper plate 114 can be suctioned and removed through the through hole 117, which opens periodically as the opening and closing means 112 of the upper plate 114 and the through hole 116 vibrate up and down. .

In the above detailed description of the present invention, only special embodiments thereof have been described. However, it should be understood that the present invention is not limited to the particular form mentioned in the detailed description, but rather is understood to include all modifications, equivalents and substitutes within the spirit and scope of the present invention as defined by the appended claims.
