Description

The sterilizing and drying apparatus of shoes comprising dehumidifier with a reduction unit of the flow velocity.

The present invention relates to a shoe sterilization and drying apparatus including a dehumidifying device having a flow rate reducing means, and more particularly, a dehumidifying device having a flow rate reducing means for reducing the flow rate of air passing through a cooling member attached to a thermoelectric element. It relates to a shoe sterilization drying apparatus comprising a.

In general, shoes worn on a daily basis become sweaty inside the shoes due to long-term use, and various bacteria grow inside the shoes, and as a result of this, an odor is generated, so that the hygiene cannot be maintained. In rainy weather, the shoes become wet with rain, and if you continue to use them in that state, it may cause bad odors or foot health problems due to the generation of moisture and bacteria inside the shoes.

Washing or natural drying is used to remove moisture and bacteria from the inside of these shoes, but since washing or natural drying is cumbersome and takes a long time, it is difficult to wear clean shoes every day.

In order to solve this problem, products using ozone, ultraviolet rays, and hot air for sterilization and drying of shoes have been proposed. However, the drying apparatus of the high-temperature drying method using hot air basically causes deformation of clothing or shoes due to high heat, so it cannot be used for clothing or shoes made of materials that are weak to heat, so there is a limitation in use, while excessive power is consumed. There is a problem that high cost is required for operation according to use. In addition, due to the hot air, the odor of shoes spreads throughout the room, making it difficult to use indoors, or indoor use due to its own fishy odor such as ozone. In addition, in the case of using ultraviolet rays, there is a problem in the sterilization effect because it is not directly touched to the deepest part where the toes of the shoe touches, or ultraviolet rays are often irradiated locally.

The storage unit 110 includes a storage space in which shoes as an object to be dried is stored, and may have a hollow hexahedral shape with an open surface. For example, the receiving unit 110 may include an upper plate and a lower plate vertically spaced apart, and left and right side plates and a rear plate connecting the upper plate and the lower plate. A door S is installed on the open side of the receiving unit 110 to open and close the receiving unit 110.

A plurality of through holes may be formed in one side plate 112 of the side plates of the receiving part 110. The plurality of through holes may include first through holes 113a communicating with a blowing passage to be described later and second through holes 113b communicating with the suction passage. Hereinafter, one side plate of the receiving portion 110 in which a plurality of through holes are formed is referred to as a side plate portion 112. The plurality of plates constituting the receiving portion 110 including the side plate portion 112 may be formed of a metal material having high thermal conductivity. For example, the receiving portion 110 (ie, the side plate portion 112) may be formed of stainless steel or aluminum. However, the present invention is not limited thereto.

The interior of the storage unit 110 may be divided into a plurality of storage spaces by at least one support member 140 installed to be detachable. The support member 140 may support a drying object (i.e., shoes) that is accommodated in the storage space and mounted on the upper surface, and has an air movement passage communicating with the first through holes 113a to provide dry air in the lower direction. It can be configured to provide. The detailed configuration of the support member 140 will be described in detail later.

The first duct member 120 may be attached to the first side surface 112_S1 of the side plate part 112 to form a ventilation passage. The ventilation passage is an air passage formed along the length direction (ie, vertical direction) of the side plate part 112, and the storage space of the receiving part 110 and the storage space through the first through holes 113a formed in the side plate part 112 Can be communicated. Here, the first side (112_S1) of the side plate portion 112 is a side that is installed in direct contact with the first duct member 120, and the second side (112_S2) of the side plate portion 112 is It may correspond to the other side exposed by the storage space. Dry air dehumidified by the dehumidifying device 200 to be described later may be supplied to the storage space through the first through holes 113a through the blowing passage.

As shown in FIG. 5, the first duct member 120 may have a shape of a hexahedron with an open side, and at the edge of the open side, the first side surface 112_S1 of the side plate part 112 is interviewed. A flange can be formed. Here, the open surface of the first duct member 120 may be referred to as a first opening 122a. Meanwhile, a second opening 122b connected to the blowing fan 300 is formed on one side of the first duct member 120, and a first duct coupling member 124 is coupled to the front facing the open side. Three openings 122c may be formed, and a fourth opening 122d through which the transfer hose 520 passes may be formed on a lower surface.

The second duct member 130 is spaced apart from the first duct member 120 and attached to the first side 112_S1 of the side plate part 112, and along the longitudinal direction (ie, vertical direction) of the side plate part 112 It is possible to form an extending suction passage. The suction passage communicates with the storage space of the storage unit 110 through the second through holes 113b formed in the side plate part 112, and air in the storage space may be sucked into the suction passage by the blower fan 300. . Like the first duct member 120, the second duct member 130 has a shape of a hexahedron with one open surface, and may be directly installed on the side plate portion 112. The lower surface of the second duct member 130 may be connected to a blowing fan 300 to be described later.

The dehumidifying device 200 uses a thermoelectric element and is installed inside the first duct member 120 (ie, inside the blowing passage), and in the air circulating through the apparatus 1 due to the heating and cooling action of the thermoelectric element. It can perform the function of removing contained moisture. The thermoelectric element has a characteristic that the temperature of one side increases and the temperature of the other side decreases when electricity is applied. Since such a thermoelectric element is a known technology, a detailed description thereof will be omitted.

The dehumidifying device 200 may be coupled to a duct coupling member 124 that seals the third opening 122c of the first duct member 120 so as to be detachably installed inside the first duct member 120 . Hereinafter, the dehumidifying device will be described in more detail with reference to FIGS. 6 to 8.

6 is an exploded perspective view illustrating a dehumidifying device according to an exemplary embodiment of the present invention. 7 is a perspective view for explaining a dehumidifying device according to other embodiments of the present invention. 8 is a plan view illustrating an arrangement relationship of upper surfaces of the flow rate reducing means according to embodiments of the present invention.

First, referring to FIG. 6, the dehumidifying device 200 includes a thermoelectric element 210, a heat dissipating member 220 and a cooling member 230 attached to both sides of the thermoelectric element 210, and a cooling and heating member 230. It may comprise at least one flow rate reducing means configured to reduce the flow rate of air passing through.

The heat dissipation member 220 is attached to one side of the thermoelectric element 210 where the temperature rises, and is attached to the other side of the thermoelectric element 210 where the temperature of the cooling and heating member 230 decreases. The heat dissipation member 220 and the cooling member 230 are made of a material having high thermal conductivity, and increase the contact area with the fluid passing through the dehumidifying device 200 to efficiently transfer heat transferred from the thermoelectric element 210 to the outside. It can be implemented to emit.

Further, the heat dissipation member 220 may be implemented to directly contact the side plate part 112 to transmit the elevated temperature of the thermoelectric element 210 to the side plate part 112. For example, the heat dissipation member 220 protrudes from the heat dissipation base plate 222 and the heat dissipation base plate 222 in contact with one side of the thermoelectric element 210, and the air flow direction (that is, in the first duct member 120). It is connected to any one of the plurality of heat dissipation heat exchange plates 224 and the heat dissipation heat exchange plates 224 having a surface parallel to the length direction), and may include a heat dissipation contact plate 226 in contact with the side plate part 112 have. The heat dissipation contact plate 226 is a configuration for increasing heat transfer efficiency by increasing a contact area with the side plate part 112, and is generally implemented in a square plate shape and may be parallel to the heat dissipation base plate 222. Unlike shown in the drawing, the heat dissipation contact plate 226 is connected to two or more heat dissipation heat exchange plates 224, or a plurality of heat dissipation contact plates 226 connected to one heat dissipation exchange plate 224, respectively. May be provided. As the heat dissipation member 220 is implemented so as to be in contact with the side plate part 112 as described above, the temperature of all storage spaces in the storage unit 110 can be increased, and in particular, the storage unit 110 and the support member 140 As provided to include a metal material having high thermal conductivity, the temperature in all the storage spaces of the storage unit 110 may be uniformly increased. Accordingly, the dehumidification capacity may be increased due to an increase in the amount of saturated water vapor in the storage space according to the increased temperature, and as a result, the dehumidification efficiency of the apparatus 1 may be further improved.

Like the heat dissipating member 220, the cooling and heating member 230 may also be implemented to have high contact efficiency with flowing air. For example, the cooling member 230 protrudes from the cooling base plate 232 and the cooling base plate 232 in contact with the other side of the thermoelectric element 210 and having a surface parallel to the flow direction of air. It may include s 234.

The air passing through the dehumidifying device 200 is condensed into condensed water due to the lowered temperature of the other side of the thermoelectric element 210, and the temperature of the air is thereby reduced while cooling the elevated temperature of one side. It passes in an elevated state. That is, as the air passing through the dehumidifying device 200 is removed by the cooling member 230, the temperature is increased by the heat emitted from the heat dissipating member 220, so that more dry air is introduced into the storage unit 110. I can.

As described above, in the air passing through the cooling member 230, moisture in the air may be condensed into condensed water due to the lowered temperature of the other side of the thermoelectric element 210. The flow rate reducing means is a configuration for reinforcing the condensation function of the cooling and heating member 230, and reduces the flow rate of air passing through the cooling and heating member 230, so that moisture in the air can be condensed by the lowered temperature. It can be implemented to provide time.

In more detail, in the case of the same relative humidity, the air flowing from the bottom to the top of the dehumidifying device 200 has a temperature at one point of the cooling member 230 lower than that of the heat dissipating member 220. Condensation due to a difference in saturated relative humidity may occur at one point of the cooling member 230. At this time, the condensation at one point of the cooling member 230 may undergo the following steps.

1. Forming the first water crystal equal to the difference in the saturation relative humidity due to low temperature

2. The step of accelerating crystal growth on the surface of the initial moisture crystal

3. The step of binding the grown water crystal to one surface of the cooling and heating member

4. When the weight of the moisture crystal attached to one side of the cooling member is greater than the surface tension, it is discharged to the bottom.

In the fourth step, condensation accelerating factors are “air to seize abundant moisture” and “time for the grown moisture crystals to bind,” and the impeding factor may be “air volume greater than or equal to.” That is, moisture crystals grow. If air is previously sent to the upper portion of the cooling member 230 with a strong air volume, crystal growth is hindered and the moisture crystals are not bound, and moisture bound to one surface of the cooling member 230 may be re-evaporated.

The flow rate lowering means can be used to perform a role of sufficiently securing a "time for the grown water crystal to bind" by weakening an obstructive factor such as the above-described "air volume above the degree".

As an example, the flow rate reducing means is connected to the upper end of the first side portion 242 and the first side portion 242 surrounding the side surface of the cooling member 230 on three surfaces, and a first upper surface covering the upper surface of the cooling member 230 It may include a first cover portion 240 having a portion 244. The first side portion 242 may have a surface parallel to the flow direction of air (ie, the length direction of the first duct member 120) and may include three surfaces surrounding the side surface of the cooling member 230. For example, the first side portion 242 may have a'C' shape in a plan view, but is not limited thereto. Each of the three surfaces of the first side portion 242 includes first inlet holes 242h through which air circulated by the blowing fan 300 is introduced, and the first upper surface portion 244 includes first inlet holes ( The air introduced through 242h may include first outlet holes 244h through which the air introduced through the cooling member 230 is discharged to the outside of the first cover part 240. Meanwhile, the lower surface of the first cover part 240 is open.

In order to enhance the condensation function of the cooling member 230, the first area ratio occupied by the first outlet holes 244h in the first upper surface portion 244 is the first inflow from each of the three surfaces of the first side portion 242 It may be desirable to be smaller than the second area ratio occupied by the holes 242h. In this case, the first area ratio may be 50 to 80%. If the first area ratio is less than 50%, the amount of condensed water may rather decrease because the fluid does not flow into the cooling member 230, and if it exceeds 80%, the effect of lowering the flow rate may be insignificant.

In addition, the flow rate reducing means may further include a second cover portion 250 surrounding the first cover portion 240 in order to more efficiently preserve the cold air inside the first cover portion 240.

The second cover part 250 is connected to both the second side part 252 surrounding the side surface of the first cover part 240 on three sides and the upper end of the three sides of the second side part 252, and the first upper surface part 244 ) May include a second upper surface portion 254 covering. Each of the three surfaces of the second side portion 252 includes second inlet holes 252h through which air circulated by the blowing fan 300 is introduced, and the second upper surface portion 254 includes second inlet holes ( The air introduced through 252h may include second outlet holes 254h through which air flows out through the cooling member 230.

Similar to the first cover portion 240, the third area ratio occupied by the second outlet holes 254h in the second upper surface portion 254 of the second cover portion 250 is three sides of the second side portion 252 It may be smaller than the fourth area ratio occupied by the second inflow holes 252h in each of. In this case, the second area ratio may be 50 to 80%. When the third area ratio is less than 50%, the amount of condensed water may be reduced because fluid flow into the cooling member 230 is not smooth, and when it exceeds 80%, the effect of reducing the flow rate may be insignificant.

On one side of the first side portion 242 of the first cover portion 240, first connecting members used to couple the first cover portion 240 and the second cover portion 250 to each other in a spaced state ( 260) may be provided, and used to couple the second cover portion 250 and the duct coupling member 124 to each other in a spaced state on one side of the second side portion 252 of the second cover portion 250 The second connecting members 270 may be provided.

As described above, the flow rate lowering means includes the air inflow and outflow holes and the first cover part 240 surrounding the cooling member 230 and the second cover part 250 surrounding the first cover part 240 As implemented as, condensation of moisture contained in the air passing through the cooling and heating member 230 proceeds more effectively, so that the dehumidification efficiency of the apparatus 1 may be further increased.

According to another embodiment, as shown in FIG. 7, the second cover part 250 may be formed of only the second upper surface part 254. Also in this case, it may be preferable that the second area ratio of the second upper surface portion 254 is 50 to 80%. In this embodiment, the first connecting members 260 provided on one side of the first side portion 242 of the first cover portion 240 are used for coupling with the duct coupling member 124, and the first upper surface portion Third connection members 280 are provided at 244 so that the first cover portion 240 and the second cover portion 250 may be coupled to each other in a spaced apart state.

Meanwhile, as shown in FIG. 8, in the upper surface portions 244 and 254 of the flow rate reducing means overlapping in a plan view, the first outlet holes 244h and the second upper surface portion ( The second outlet holes 254h of 254 may not be vertically aligned with each other. In other words, in a plan view, the first outlet holes 244h and the second outlet holes 254h may or may not partially overlap. Through this, it is possible to further increase the effect of reducing the flow rate of air by the flow rate reducing means.

Although not shown, the dehumidifying device 200 may further include a heat insulating member (not shown) disposed between the heat dissipating member 220 and the cooling member 230 and surrounding the edge of the thermoelectric element 210.

Again, referring to FIGS. 1 to 5, the blowing fan 300 may connect the first duct member 120 and the second duct member 130 and circulate air in the storage unit 110. Air circulated by the blowing fan 300 is introduced into the storage unit 110 through the first through holes 113a through the blowing passage formed by the first duct member 120, and the first through holes 113b By being sucked into the blowing fan 300 through the suction passage formed by the second duct member 130 and the second duct member 130, it can be closed and continuously circulated within the device 1. The blowing fan 300 may be implemented as a known blowing device having an air volume to facilitate and quickly circulate air passing through the first duct member 120, the receiving unit 110, and the second duct member 130. I can.

The negative ion generator 400 may generate negative ions for sterilizing and purifying an object to be dried (eg, shoes) in the storage unit 110. For example, the negative ion generator 400 may be mounted on the first side 112_S1 of the side plate 112 from the inside of the first duct member 120, and through the air circulated by the blowing fan 300, the receiving part ( 110) can supply negative ions into the inside. Since the negative ion generator 400 may use a known negative ion generating device, a detailed description thereof will be omitted.

The condensed water storage unit 500 may store water condensed by the dehumidifying device 200. For example, as shown in FIG. 5, a drip tray 510 for guiding the water condensed through the dehumidifying device 200 to the condensed water storage unit 500 is provided at the lower end of the first cover unit 240, The transfer hose 520 may be connected to the lower surface of the drip tray 510 to transfer the condensed water to the condensed water storage unit 500. The cooling member 230 condenses moisture in the air on its surface due to contact with air to generate condensed water, and the condensed water accumulates in the drip tray 510 coupled to the lower surface of the first cover part 240. In addition, when the condensed water is discharged to the condensed water storage unit 500 through the transfer hose 520 and removed, moisture in the air is removed and the air is dried. Since the drip tray 510 has a shape inclined toward the center, it may be easier to accumulate condensed water. The condensed water storage unit 500 has a substantially hexahedral cylindrical shape capable of storing condensed water, and may be configured to be detachable from the device 1.

The sensor unit 600 may include a temperature/humidity sensor 610, a door opening/closing sensor 620, a condensed water level detecting sensor 630, and a condensed water storage unit position detecting sensor 640.

The temperature and humidity sensor 610 may measure the temperature and humidity of air sucked from the storage unit 110. For example, the temperature/humidity sensor 610 may be installed inside the second duct member 130 and measure the temperature and humidity of air sucked into the suction passage through the second through holes 113b. The temperature and humidity information measured by the temperature and humidity sensor 610 is transmitted to the control unit 700, and the control unit 700 controls the operation of the dehumidification device 200 and/or the negative ion generator 400 using the received temperature and humidity information. Can be controlled.

The door opening/closing sensor 620 is installed on the upper plate of the receiving unit 110 and may detect whether the door S is opened or closed. The detected door opening/closing information is transmitted to the controller 700, and the controller 700 may control the operation of the dehumidifying device 200 and/or the negative ion generator 400 by using the transmission door opening/closing information.

The condensate level detection sensor 630 and the condensate storage unit position detection sensor 640 are provided in the condensate storage unit 500, respectively, and determine whether the condensate level in the condensate storage unit 500 and the condensate storage unit 500 are positioned correctly. Can be detected.

The controller 700 may control the overall operation of the shoe sterilization and drying apparatus 1. When the device 1 is operated by pressing the power button, the controller 700 may fully automatically drive the device 1 without any additional setting through an artificial intelligence algorithm.

For example, the control unit 700 is based on at least one of temperature information, humidity information, door opening and closing information, condensate level detection information, and condensate location information transmitted from the sensor unit 600, the dehumidifying device 200 and the negative ion generator. The operation of the 400 may be controlled, and an alarm (eg, LED lighting or a buzzer sound) may be generated when an abnormal situation of the condensate storage unit 500 is detected. Here, the abnormal situation of the condensate storage unit 500 is when the condensate water level exceeds the reference value or the location of the condensate storage unit 500 deviates from the original position (eg, when the condensate storage unit 500 is open, etc.) Can mean

In detail, when the measured value of the temperature or humidity received from the temperature and humidity sensor 610 is out of a preset reference range or reference value, the control unit 700 operates the dehumidifying device 200 (that is, the thermoelectric element 210). You can stop. For example, when the temperature exceeds the upper limit of the reference temperature (for example, 40°C), the control unit 700 may stop the operation of the thermoelectric element 210, and a certain time elapses after the operation is stopped or the measured temperature When the temperature falls within the reference temperature range (eg, 25 to 40°C), the thermoelectric element 210 may be restarted. As another example, when the measured humidity is less than the reference humidity (for example, relative humidity 20%), the controller 700 may stop the operation of the thermoelectric element 210, and a certain time elapses after the operation is stopped or the measured humidity is the standard. When the humidity is higher than, the thermoelectric element 210 may be restarted.

In addition, the control unit 700 may calculate the storage time of the object to be dried stored in the storage unit 110 based on the received door opening/closing detection information, and when the storage time has elapsed, the thermoelectric element 210 Can be stopped. In addition, when the door S is opened, the controller 700 may turn on the lighting provided in the receiving unit 110.

The operation mode of the dehumidifying device 200 and the negative ion generator 400 and an abnormal condition of the condensed water storage unit 500 may be displayed on the display unit 800. The display unit 800 may be provided at an upper end of one side of the front portion of the housing 100 on which the door S is installed. In addition, a power button may be provided on the display unit 800.

The control unit 700 maintains the temperature in the storage unit 110 in a certain range, does not operate at low humidity, and controls the thermoelectric element 210 so that it does not operate continuously for a long time, thereby increasing dehumidification efficiency. Of course, it is possible to prevent deformation of the object to be dried due to thermal damage, and to operate the shoe sterilization and drying apparatus 1 at low cost without using excessive power.

Optionally, the shoe sterilization and drying apparatus 1 may further include a filter member (not shown). The filter member is for removing odor and fine dust in the receiving part 110, and is installed on the first side 112_S1 of the side plate part 112 so as to overlap with the second through holes 113b of the side plate part 112 Can be. The filter member may include at least one of an air filter and a deodorization filter. The air filter may include a HEPA filter or a wool filter, and the deodorization filter may include an activated carbon filter or a carbon filter. Meanwhile, the control unit 700 may generate an alarm when the expiration date of the filter member mounted on the side plate 112 has elapsed.
