Description

{Device to keep shoes clean}

The present invention relates to a shoe cleaning device that can remove dust and foreign substances from the surface of shoes and dehumidify and sterilize wet shoes on rainy days.

As modern people's standard of living improves, their interest in well-being is growing, and in particular, foot health begins with the cleanliness of the shoes on which they spend most of their time. However, if they take off their shoes indoors, the bad smell from their feet is transmitted to those around them.

Unpleasant shoe odor is caused by bacteria contaminated with shoes, and the bad smell of shoes must be removed by sterilizing them. Generally, methods for sterilizing shoes include heating, chemical disinfectants, drying, and sterilizing with ultraviolet rays.

In this way, it is easy to disinfect feet and socks, but serious problems arise with shoes, such as damage when using chemical disinfectants or boiling them, and the natural drying method alone has the disadvantage of low sterilization effect and takes a long time.

In addition, the existing sterilizers used for shoes are not automated for single use, which is not suitable for modern society, and although they are meant to be used indoors, they do not have a separate dust removal function, and the devices are heavy and bulky, etc.

Accordingly, there is an urgent need to develop a simple device that can solve these problems and be used for multiple purposes.

Therefore, it should be understood that there may be various equivalents and modified examples that can replace them at the time of filing this application.

Hereinafter, a shoe cleaning device according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 16.

The shoe cleaning device according to the present invention enables foreign substances that lower the cleanliness of the surface of a shoe (S) to be removed without a person using a motor fan-equipped air nozzle unit (60), and foreign substances spread inside a case (10) are collected at the bottom through a blower (70) using a centrifugal fan so that dust can be easily removed using a strainer (80), and the inside of the shoe (S) is dehumidified using hot air and sterilized using a sterilization unit (50) using a UV LED lamp, so as to maintain and increase the cleanliness of the inside, and includes a case (10), a connecting line (20), a holding unit (30), a dehumidifying unit (40), a sterilizing unit (50), an air nozzle unit (60), a blower (70), and a strainer (80).

The above case (10) forms a hollow installation space inside and is provided with a cover (12) that can be opened and closed on the top.

As an example, the present invention configures a case (10) having a square shape, and the cover (12) has a '┍' shape.

Of course, the cover (12) is connected to the case (10) with a connecting pin (14) (ex: hinge, etc.) so that the cover (12) can be opened and closed by rotating left and right based on the connecting pin (14), or

The above case (10) forms a protrusion (11) that protrudes from a side wall, and forms a recessed portion (13) on one side of the cover (12) that corresponds to the protrusion (11) and fits into it, so that they correspond to each other and fit together, and then a connecting pin (14) is installed through the protrusion (11) and the recessed portion (13) so that they are connected to each other by the connecting pin (14), and when the connecting pin (14) is removed, the case (10) and the cover (12) can have a structure in which they are separated. If the internal structure is capable of being opened and closed, this structure can be changed in various ways.

In addition, in order to check the level of cleaning or the interior of the shoe (S) inside, one side of the cover (12) may be installed with a transparent plate material so that the interior can be identified.

The above connecting line (20) is an installation stand that is bent downward in a gentle arc shape on the upper left side of the inside of the case (10), and is configured to allow the mounting part (30) to be installed integrally so that the mounting part (30) can be fixed to the inside of the case (10).

According to the user's embodiment, the connecting line (20) can be flexibly moved (a flexible structure or material can be used) and the angle can be adjusted, so that the angle of placement of the mounting portion (30) on which the shoe (S) to be installed is mounted can be adjusted.

The above-mentioned mounting part (30) is installed horizontally as one piece at the end of the aforementioned connecting line (20), but has a shape corresponding to the internal shape of the shoe (S) so that it can be fitted inside the shoe (S), and is configured to form an 'L'-shaped euro line (31) directed forward from the upper part of the shoe (S) and formed inside.

Of course, if this mounting part (30) corresponds to the inside of the shoe (S) and is fitted so that the shoe (S) can be fixed in position at a certain angle and the shoe (S) is not easily removed from this mounting part (30), this shape can be modified in various ways.

The above dehumidifying unit (40) is a dehumidifying device that provides hot air so that the heat generated by the heating module (41) installed inside the aforementioned mounting unit (30) and generating heat, and the heating fan (42) rotatably installed on one end of the flow line (31) on the upper surface of one side of the mounting unit (30) is discharged to the front of the shoe (S) along the flow line (31) when the heating fan (42) is driven, and then reflected from the front to allow heat flow to the back of the shoe (S).

Of course, the hot air discharged to the front of the shoe (S) moves to the back of the shoe (S), then is discharged to the outside of the shoe (S), passes through the inside of the case (10), and is discharged to the air vent (70) described later.

As the above heating module (41), a PTC (Positivie Temperature Coefficient) heating module (41) is used, and as shown in FIG. 13, when the heating module (41) is 80°C, the relative humidity inside the shoe (S) can be dehumidified most efficiently, and when the heating module (41) is 60°C, the overall temperature inside the shoe (S) is closest to 32°C, which is the preset temperature inside the shoe (S) set in the present invention, and can be seen to be evenly distributed.

The above sterilization unit (50) is a UV lamp sterilization device that uses a UV LED lamp (more precisely, UV_C LED) to sterilize the inside of a shoe (S) and is installed in corresponding grooves installed on both sides of the outer periphery of the aforementioned mounting unit (30).

The above air nozzle part (60) is installed so as to penetrate from the outside to the inside on the right side of the case (10) described above, but is arranged diagonally so as to face the other end of the euro line (31) of the mounting part (30), and a nozzle fan (61) is installed on the outside to spray external air onto the surface of the shoe (S), thereby removing foreign substances on the outside of the shoe (S).

In the air nozzle part (60) of the present invention, the diameter of the internal flow path (62) gradually decreases from the outside of the case (10) toward the inside, thereby allowing the flow rate to gradually increase due to the throttling phenomenon, thereby supplying a constant flow rate of air to the surface of the shoe (S) to remove foreign substances.

The above air vent (70) is installed at the bottom of the case (10) and is an air exhaust section that uses a centrifugal fan (or centrifugal blower) to collect air containing foreign substances inside the case (10) toward the bottom of the case (10) and discharge it to the outside.

That is, foreign substances spread inside the case (10) are gathered to the bottom of the case (10) using a centrifugal blower, which is an intake fan.

The above filter net (80) is installed above the air vent (70) at the bottom of the case (10) and is a net that filters foreign substances in the air of the case (10). A high efficiency particulate air filter (HEPA) fabric is inserted into the filter net (80) to filter foreign substances on the surface of the shoe (S).

That is, it is a configuration in which filtered air coming out through the filter net (80) is exhausted to the outside through the above-mentioned air vent (70).

In addition, in the present invention, a brush-shaped dusting brush for dusting the outside of a shoe (S) can be installed rotatably and used inside the case (10) described above through various user embodiments.

In the case of a shoe cleaning device having the above configuration, two modes are provided: a general mode used in normal times when it does not rain, and a rainy mode used to clean wet shoes (S) when it rains, so that operation can be selectively performed in either the general mode or the rainy mode.

The above rainy weather mode is

Nozzle fan (61) driving step (S100) of the above air nozzle part (60);

Centrifugal fan driving step (S200) of the above blower (70);

The above sterilization unit (50) driving step (S300);

The driving stage (S500) of the heating fan (42) of the above dehumidifying unit (40);

Step (S600) of maintaining the internal temperature of the case (10) at a preset temperature by measuring the internal temperature through a temperature sensor in the case (10), stopping the operation of the heating fan (42) when the measured temperature falls within the preset temperature range, and restarting the operation of the heating fan (42) when the measured temperature falls below the preset temperature range, for 30 to 40 minutes;

After the above S500 step, when 5 minutes have passed since the heating fan (42) was turned off, the process is performed in the following order: step (S700) of turning off all operating devices.

The above general mode is the same as the rainy weather mode, but between the sterilization unit (50) driving step (S300) and the dehumidification unit (40) heating fan (42) driving step (S500), a 5-minute driving step (400) of a dust brush rotatably installed inside the case (10) to dust the surface of the shoe (S) is added and driven.

As described above, although the present invention has been described by means of limited embodiments and drawings, the present invention is not limited thereto, and various modifications and changes are possible by a person skilled in the art to which the present invention pertains within the technical spirit of the present invention and the scope of equivalents of the patent claims to be described below.
