First, the housing 10 is a case that receives and protects the internal structure 20 therein. In particular, the housing 10 may be formed in a circular shape or an oval shape in the front direction to improve the aesthetic feeling of the small size, but the present invention is not limited thereto.

Specifically, the housing 10 may include a first housing 110 to a third housing 130. That is, the first housing 110 may include a suction port 111 formed to suck air, and the input unit 40 may be located. In addition, the first housing 110 may be formed in a circular panel shape forming the front portion of the housing 10. The second housing 120 may be fastened to the first housing 110 and may be formed in a ring shape forming a part of the housing 10. The third housing 130 may be fastened to the second housing 120, and may be formed in a circular basket shape with its front surface open to form the remaining side and rear portions of the housing 10. At this time, the first housing 110 and the second housing 120 may be formed integrally without being separated, but the present invention is not limited thereto.

The second housing 120 or the third housing 130 may include an outlet 131 formed to discharge air on both sides of a surface corresponding to the side surface of the housing 10. In addition, the second housing 120 or the third housing 130 may include a water bottle entrance 121 formed to allow the water bottle 30 to be inserted into one side of the surface corresponding to the side surface of the housing 10. At this time, in consideration of the position of the water bottle 30 and the air position discharged from the inside of the housing 10, the water bottle entrance 121 may be preferably formed to be located below the discharge hole 131. However, in FIGS. 1 and 2, the outlet 131 is shown as being formed only in the third housing 130, and the water outlet 121 is shown as being formed in the second housing 120 and the third housing 130. , The present invention is not limited to this.

Figure 6 shows a state diagram of the folding base 50 is unfolded in the dehumidifier 1 using a thermoelectric element according to an embodiment of the present invention, Figure 7 is a dehumidifier using a thermoelectric element according to an embodiment of the present invention ( 1) shows a use state diagram in which the water bottle 30 and the filter structure 70 are inserted.

Meanwhile, in the second housing 120 or the third housing 130, a lower outer surface of a surface corresponding to a side surface of the housing 10 is formed in a curved shape. At this time, as shown in FIG. 6, on the corresponding surface, a pedestal accommodating part 122 that is a space for accommodating the foldable pedestal 50 may be formed. In addition, the third housing 130 is an insertion hole 123 formed to allow the filter structure 70 to be inserted into the upper surface or one side of the surface corresponding to the back surface of the housing 10 or the surface corresponding to the side surface of the housing 10. It may be provided. At this time, the third housing 130 may be provided with a cover 124 detachably attached to the insertion hole (123).

Next, the internal structure 20 is a configuration provided inside the housing 20, and includes a cooling module 210, a fan 220, a main board 230, an inner frame 240, and a power supply 250 can do.

Specifically, the cooling module 210 is configured to cool the air sucked through the intake 111, as shown in Figure 4, the thermoelectric element 211, and a plurality of first heat dissipation fins (212a) on the front The first heat sink 212 disposed on the front surface of the thermoelectric element 211 and the second heat sink 213 disposed on the rear surface of the thermoelectric element 211 are provided with a plurality of second heat radiation fins 213a on the rear surface. Each includes.

At this time, the thermoelectric element 211 is an element that absorbs heat and exothermic due to the Peltier effect, and the heat absorbing portion 211a that absorbs heat is located on the front side, and the heat generating portion 211b that heats on the back side is located on the back side. Accordingly, the first heat sink 212 disposed on the front surface of the thermoelectric element 211 may contact the air to cool the air to condense water vapor contained in the air into water. In addition, the second heat sink 213 disposed on the rear surface of the thermoelectric element 211 may contact the air to heat the air.

The fan 220 is configured to provide a driving force for the formation and control of the intake and exhaust air flows, and is disposed on the rear surface of the second heat sink 213. At this time, the fan 220 injects air toward the rear surface of the second heat sink 213. That is, the fan 220 has a blade shape that sucks air from the rear surface and discharges air to the front surface during operation.

Specifically, the air flow formed by the operation of the fan 220 is as follows. That is, referring to FIGS. 4 and 5, i) air is sucked into the housing 10 through the suction port 111, and ii) the sucked air is in contact with the first heat sink 212 that cools, while air The water vapor inside condenses into water, and iii) the rest of the air that is not condensed is sucked to the rear surface of the fan 220 and sprayed to the front surface, and iv) the sprayed air is discharged after contacting the second heat sink 213, which is exothermic. It is discharged to the outside through (131). However, the source of air flow according to i) to iv) is in the operation of the fan 220 in iii). That is, when the fan 220 is operated, the air flow of the air intake action and the air exhaust action according to i) to iv) occurs together.

In the conventional case, a plurality of fans are provided, and in particular, since the fans for air intake and the fans for air discharge are separately provided, the durability structure is inevitably complicated, and accordingly, there is a limitation in reducing the volume, so there is a problem that miniaturization is impossible. . However, as described above, since the present invention is implemented to form the above-described air flow with only one fan 220, the volume can be reduced more than in the related art, thereby miniaturizing. However, the present invention does not exclude that fans other than the above-described fan 220 are added.

In particular, the first heat dissipation fins 212a may extend upward and downward to be spaced apart. That is, as illustrated in FIGS. 4 and 5, when the first heat dissipation fin 212a is formed to extend upward and downward, in ii), air is guided upward along the shape of the first heat dissipation fin 212a. In addition to being able to rise more smoothly, water generated by the cooling action of the first heat dissipation fin 212a can be more smoothly accommodated in the water bottle 30 while being guided along the shape of the first heat dissipation fin 212a. At this time, the air intake 111 is formed at a position corresponding to the front surface of the first heat dissipation fin 212a, so that the air flow of the air intake according to i) and ii) can be made more smooth.

In addition, the second heat dissipation fins 213a may extend toward the side and be spaced apart. That is, as illustrated in FIGS. 4 and 5, when the second heat dissipation fin 213a is formed to extend toward the side, in iv), air is side along the shape of the second heat dissipation fin 213a that exerts heat. It can be discharged to the outside through the outlet 131 more smoothly while being guided. At this time, the air outlet 131 is formed at a position corresponding to the side surface of the second heat dissipation fin 213a, so that the air flow of the air discharge action according to iv) can be more smoothly performed.

The main board 230 includes various circuits such as a control unit for controlling for various dehumidification operations. At this time, the main board 230 may be connected to the input unit 40, the thermoelectric element 211, the fan 220, or the power unit 250, respectively, to process input and output of signals and power. That is, the main board 230 may transmit signals and power necessary for controlling various dehumidifying operations according to an operation command input from the input unit 40. In addition, the main board 230 is connected to various sensors, such as a temperature sensor and a humidity sensor, to supply power to these sensors and receive and process sensor signals from these sensors.

The inner frame 240 is a component that secures these components inside the housing 10 by seating the input unit 40, the cooling module 210, the fan 220, and the power unit 250.

The power supply unit 250 is a power supply (SMPS: switched mode power supply). That is, the power supply unit 250 receives commercial power and processes it to provide the processed power to the input unit 40, the thermoelectric element 211, the fan 220, or the main board 230. For example, the power supply unit 250 may convert 220V AC power to DC power of a predetermined size to provide the converted power to the configuration, but the present invention is not limited thereto.

On the other hand, the greater the difference ΔT between the temperature T _c of the heat absorbing portion 211a and the temperature T _h of the heat generating portion 211b, the lower the current flowing through the thermoelectric element 211. In the case of a conventional dehumidifier, a large ΔT was formed in a short time by supplying a voltage corresponding to the maximum value to the thermoelectric element 211 during initial driving. However, in this case, the current flowing through the thermoelectric element 211 for a time other than the initial driving time (that is, after the initial driving time) is about 70% or less of the initial driving current. That is, when the capacity of the power supply unit 250 is selected based on the initial driving current as in the related art, since the unnecessary capacity corresponding to about 30% needs to be secured, the capacity of the power supply unit 250 increases, thereby making the product Price and size will increase.

In order to solve the capacity problem of the power supply unit 250, it may be desirable to design the power supply unit 250 as follows. That is, when power is supplied to the thermoelectric element 211, the power supply unit 250 supplies a voltage of V ₁ lower than the maximum voltage (V _max ) for a time during the initial driving time t ₁ , and after t ₁ hour (that is, the initial driving time) After that, V ₁ <V ₂ <V _max satisfying V ₂ may be supplied. At this time, t ₁ may be 5 to 10 minutes, but the present invention is not limited thereto.

For example, if V ₁ corresponding to 70% of the maximum voltage V _max (for example, 12 V) is supplied during the initial 5 minutes to 10 minutes of driving, △ T gradually increases during the corresponding time and 50% of the maximum current Only the degree flows to the thermoelectric element 211. Thereafter, even if V ₂ corresponding to a voltage (for example, 17 V) is supplied after the initial driving, since ΔT is increased, there is no other problem in the capacity for supplying power to the thermoelectric element 211. Therefore, since the power supply unit 250 can reduce its capacity than the conventional one, its price and size can also be reduced.

On the other hand, when the ambient temperature is low, the temperature around the heat absorbing portion 211a of the thermoelectric element 211 may drop below zero. In this case, dehumidification efficiency may be reduced or product failure may occur as water condensed by the endothermic action of the heat absorbing portion 211a freezes.

In order to solve this problem of water coagulation, the present invention can perform a defrost function. That is, when the ambient temperature at the initial stage of driving is equal to or less than the first temperature, the power supply unit 250 may supply power again after stopping supplying power to the thermoelectric element 211 for a period of time t _{3 at} the initial stage of driving. At this time, the first temperature may be 0°C to 5°C, and t ₃ may be 5 minutes to 10 minutes, but the present invention is not limited thereto.

For example, when the temperature measured by the temperature sensor provided around the heat absorbing unit 211a in the initial stage is 0°C or less, the power source unit 250 stops supplying power to the thermoelectric element 211 during the initial 5 minutes of driving. Can. Subsequently, when the measurement temperature becomes 5°C or higher, the power supply unit 250 may supply power to the thermoelectric element 211 again. Through this operation, the present invention can perform the defrosting function at the initial stage of driving.

In addition, for an additional defrosting function, the power supply unit 250 supplies power to the thermoelectric element 211 for a time of t ₅ every t ₄ when the ambient temperature, that is, the outside temperature is below a second temperature higher than the first temperature. After stopping, it can be fed again. In this case, the second temperature may be 10°C to 15°C, t ₄ may be 30 minutes to 1 hour, and t ₅ may be 5 minutes to 10 minutes, and the present invention is not limited thereto.

For example, when the ambient temperature is 15° C. or less, the power supply unit 250 may stop supplying power to the thermoelectric element 211 for about 5 minutes every hour. Through this operation, the present invention can perform the defrosting function after the initial driving. At this time, the outside air temperature may be measured through a separate outside temperature measurement sensor, or may be estimated through the temperature of the thermistor detecting the overheating of the second heat sink 213, but the present invention is not limited thereto.

Next, the water bottle 30 is configured to receive water condensed by a cooling action on air, and has a receiving portion 31 that is open toward the top. That is, the water bottle 30 can be inserted into the housing 10 through the water bottle entrance 121 formed in the housing 10.

When inserted into the housing 10, the water bottle 30 has an opening in which the opening portion is located below the first heat dissipation fin 121a, but the receiving portion 31 is positioned at a position capable of receiving water condensing and falling from the first heat dissipation fin 121a. It can be formed to be located. Particularly, since the water bottle 30 can be inserted and taken out in a sliding manner on one side of the housing 10, it is possible to maintain the shape of a circle or the like in the front direction of the housing 10, so that the housing 10 is You can preserve the aesthetic sense.

In particular, the water bottle 30 can contribute to the miniaturization implementation of the present invention due to its equipped position and its side sliding method. That is, since the housing 10 is in the form of a circle or the like, as the water bottle 30 is provided in a side sliding manner in the remaining space below, the space wasted inside the housing 10 can be reduced. In addition, this effect can be further enhanced by arranging the power supply unit 250 in the remaining rear space occupied by the water bottle 30 at the lower side of the housing 10.

On the other hand, in the case of the conventional dehumidifier, the user had to carry out the water bottle 30 to empty the water, causing inconvenience. In order to solve this inconvenience, the dehumidifier 1 using a thermoelectric element according to an embodiment of the present invention, as shown in Figure 3, may further include a drainage device (60). That is, the drainage device 60 is a configuration provided so that the water of the water bottle 30 is naturally carried out to the outside, and includes a cap 61, an auxiliary water bottle 62 and a drain pipe 63.

Specifically, the cap 61 is detachably provided in the through hole 33 formed in the bottom surface 32 of the opening portion of the water bottle 30. That is, when the user of the water in the water bottle 30 is used in an emptying manner, the cap 61 is worn in the through hole 33. On the other hand, when the water of the water bottle 30 is used in a manner that is naturally carried out, the cap 61 is removed from the through hole 33.

The auxiliary water bottle 62 is positioned below the water bottle 30 inserted into the housing 10 to receive water. That is, the auxiliary water bottle 62 accommodates water that is filled in the water bottle 30 and falls from the through hole 33 when the cap 61 of the water bottle 30 inserted in the housing 10 is removed.

The drain pipe 63 is connected to the auxiliary water tank 62 and discharges water filled in the auxiliary water tank 62 to the outside. At this time, the drain pipe 63 can naturally discharge water to the outside depending on the pressure. However, a pump for discharging water may be connected to the drain pipe 63, but the present invention is not limited thereto.

Next, the input unit 40 is configured to receive a dehumidifying command from a user, and may penetrate the first housing 110 and be exposed on the front surface of the housing 10. For example, the input unit 40 may be formed by a touch method or a push method, but the present invention is not limited thereto. In addition, a display may be provided around the input unit 40 to display input commands, set dehumidification functions, and ambient air conditions.

On the other hand, the dehumidifier 1 using a thermoelectric element according to an embodiment of the present invention, as shown in FIG. 6, the foldable pedestal 50 provided to be accommodated in the pedestal receiving portion 122 of the lower housing 10 ) May be further included. That is, as the housing 10 is formed in a circular shape, the lower outer surface of the housing 10 is also formed in a curved shape, so the present invention may not be easily erected on the bottom surface. Complementing this, the folding base 122 is designed to be unfolded when necessary in a folding manner, so that the present invention can be used for a stand. In addition, because of this folding method, the folding base 122 is folded in the base receiving section 122 in a normal manner, thereby reducing the volume of the present invention, thereby contributing to the implementation of a compact dehumidifier.

In addition, the dehumidifier 1 using a thermoelectric element according to an embodiment of the present invention may be used as both a wall mount and a stand. That is, when the present invention is used for a stand, the above-described folding pedestal 122 may be used. In addition, when the present invention is used for wall-mounting, the bracket can be fixed to the wall by installing the bracket in a bracket installation portion (not shown) formed in the housing 10. For example, the bracket mounting portion may be a threaded groove into which a screw pin can be inserted, but the present invention is not limited thereto.

Meanwhile, the dehumidifier 1 using a thermoelectric element according to an embodiment of the present invention may further include a filter structure 70 as illustrated in FIG. 7. At this time, the filter structure 70 is a structure including at least one filter, it is possible to insert and carry out/exchange/exchange through the insertion hole 123 of the housing 10, in particular by being located on the rear surface of the fan 220, the fan The air flowing into the rear surface of 220 may be filtered. For example, the filter may be a pre-filter, a hepa filter, or a deodorizing filter, but the present invention is not limited thereto. When the filter structure 70 is provided as described above, the present invention can simultaneously implement dehumidification and purification for ambient air.

In particular, the filter structure 70 may further include a fragrance sheet (not shown). At this time, the fragrance sheet is to provide fragrance, such as an aromatic sheet, it is possible to insert and take out / exchange through the insertion hole 123 of the housing 10. However, the fragrance sheet may be inserted into the housing 10 separately from the filter structure 70, and a separate perforation may be provided in the housing 10 for insertion of the fragrance sheet. In particular, the fragrance sheet may be located between the filter and the fan 220. When the fragrance sheet is provided as described above, the present invention can simultaneously dehumidify and deodorize the surrounding air by discharging the fragrance generated by the fragrance sheet.

On the other hand, since the conventional dehumidifier is a relatively bulky product, it cannot be placed inside a fashion miscellaneous goods storage device such as a shoe cabinet or a closet with a small internal space. However, since the present invention can be manufactured in a very small size, there is an advantage that can be utilized for the internal arrangement of the fashion sundries storage device. Particularly, when the fragrance sheet is provided, the present invention has the advantage of being able to simultaneously implement the dehumidifying and scenting function inside the fashion miscellaneous goods storage device, thereby increasing the utilization.
