Description

Dehumidifier with air purifier {dehumidifier with air purifier}

The present invention relates to a dehumidifier, and in particular, the dehumidification action uses a thermoelectric element plate without using ozone as a refrigerant, and the air purification action relates to a dehumidifier having an environmentally friendly air purifier by using an ozone generator.

In general, a dehumidifier that removes moisture contained in air is a cooling dehumidifier that removes moisture by condensing moisture in the air on the surface of the coil when the surface temperature of the cooling coil is lower than the dew point temperature. The temperature rises and the compressed air cools down to a saturation temperature, whereby the moisture condenses. A dehumidifier that absorbs moisture from the absorption tower by spraying lithium chloride (Licl) solution and absorbent liquid. There are various types of dehumidifiers such as adsorption type dehumidifiers that dehumidify moisture in humid air using adsorbents such as silica gel and activated alumina.

The dehumidifier using the refrigeration cycle of the cooled dehumidifier is equipped with an air suction fan for sucking wet air in the dehumidifier case, a normal refrigeration cycle apparatus is installed on the front side of the air suction fan, and among the above-mentioned refrigeration cycle apparatus At the bottom of the evaporator is a reservoir where water condenses and the dripping water accumulates.

The dehumidifier using the refrigeration cycle as described above, the air suction fan is rotated by the power applied first to suck the high temperature and high humidity air into the case. As the hot and humid air sucked in this way passes over the surface of the evaporator cooled by the evaporation of the refrigerant, the temperature of the sucked air is cooled below the dew point. Therefore, the moisture contained in the air collects as dew and collects in the reservoir. The low temperature dry air passing through the evaporator cools the condenser and the compressor at the rear of the evaporator, and the dehumidified air is raised to room temperature and discharged.

However, the dehumidifier using the refrigeration cycle as described above is to use a refrigerant, typically using a freon gas. Since the freon gas is a stable material, it is hardly decomposed in the troposphere. However, the freon gas that has risen to the ozone layer about 25km above the surface of the earth is broken down by ultraviolet rays and destroys the ozone layer. Currently, international environmental conventions regulate the use of freon gas. That is, there is a problem that the dehumidifier using Freon gas is not environmentally friendly.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention is first to provide a dehumidifier that removes moisture by a new environmentally friendly method that does not use a freon refrigerant, and secondly, in humid air It provides not only the function of removing moisture, but also a dehumidifier with the function of purifying the air. Third, when the dehumidifier is installed on the wall, the wall is attached to prevent the mold from occurring in the space between the wall and the dehumidifier. To provide a dehumidifier.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, and like reference numerals designate like parts throughout the drawings.

1 and 2 are an overall perspective view and a partially cut perspective view of a dehumidifier with an air purifier according to a first embodiment of the present invention, Figure 3 is a side cross-sectional view of the dehumidifier.

As shown in the drawing, a dehumidifier having an air purifier according to the present invention, which is indicated by reference numeral 100, is a box-shaped housing 10 constituting a main body, and a dehumidifier installed inside the housing to remove moisture. And an air purifying member for purifying air from which moisture is removed from the dehumidifying member.

The housing 10 constituting the main body of the dehumidifier has a protrusion guide 12 formed on the rear portion so as to be spaced apart from the wall surface by a predetermined distance when attached to the wall surface, and is attached to the wall by bolts or the like using the protrusion guide 12. In addition, the front suction part 14, the rear suction part 16, the rear suction part 16, and a pair of side suction parts 15 are formed at both sides of the lower part of the front lower part through which the outside air can be sucked into the inside. In addition, an exhaust port 18 is formed at an upper portion so that the air sucked from each of the intake ports 14, 15, and 16 is discharged. The moisture removed from the dehumidifying member is liquefied and the drain hole 19 is discharged to the outside. It is formed in the lower portion of the housing (10).

The dehumidifying member does not remove moisture by using a refrigerating cycle, but rather on both sides of the thermoelectric element 50 and the thermoelectric element 50 using the phenomenon of absorbing heat by electric current (Peltier effect). The formed cold sink 52, heat sink 54, etc. are comprised.

The Peltier effect refers to a phenomenon in which two types of metal tips are connected to each other and a current flows therein, resulting in endothermic heat on one terminal and heat generation on the other terminal. The formula is as follows.

┃Qp┃ = αabTjI = πI

┃Qp┃ = Absolute value of calories generated in unit time. αavTj = π = Peltier coefficient, I = current, αab = relative thermoelectric power of a.b bimetals according to ambient temperature,

In other words, the Peltier effect is the release and absorption of heat that occurs when a current flows through a junction between two different materials, and if heat is generated when current flows in one direction, it absorbs heat when current flows in the opposite direction. The Peltier effect is reversible. When current flows through the junction, heat generation or absorption by the peltier effect occurs in addition to the joule thermal effect generated when the current flows through the conductor. When electrons flow from metal to semiconductor, the electrons in the Fermi level of the metal must move into the conduction band of the semiconductor. Therefore, when the conduction electrons move from the metal to the semiconductor, the average kinetic energy must increase by ΔE, and the change in the kinetic energy is caused by the absorption of heat. That is, thermal energy is used to increase the average energy of the electrons.

The thermoelectric element plate 50 used in the present invention using the Peltier effect has a flat plate shape as shown in the drawing, and the front suction port 14 has a heat absorbing plate where endothermic occurs due to electric current. The heating plate is to be located.

The heat absorbing plate and the heat generating plate are adjusted in the direction of the (+) and (-) poles of the supplied power.

A plurality of cooling plates are attached to the heat absorbing plate to increase the heat absorbing action. The cooling plate cools the humid air flowing from the front suction port 14 by increasing the contact area with air. That is, in the cold sink 52 composed of the heat absorbing plate and the cooling plate, the incoming air is cooled, and dew condensation occurs when condensation occurs when the hot and humid air is cooled in the cold sink 52 below the dew point. It will be attached to the plate. In addition, when the dew is collected and the water droplets fall by their own weight, the water drops are collected in a reservoir (not shown) installed outside through the drain hole 19.

As the high temperature and high humidity air passes through the cold sink 52, the low temperature dry air passes through the lower portion of the thermoelectric element plate 50 to form the other side of the thermoelectric element plate 50. The heat sink 54. The heat sink 54 includes a heating plate that generates heat in the thermoelectric element plate 50 and a plurality of heating plates attached to the heating plate to increase a contact area with air. In the heat sink 54, the low temperature dry air is heated to be similar to the external air temperature, thereby supplying air to the air purification member described later. Since the thermoelectric element plate 50 used in the present invention should use a DC power source, a converter (not shown) for converting an AC power source into a DC voltage source is mounted.

The air purifying member is a device for sterilizing bacteria or bacteria in the air and, according to the present invention, purifies the air using ozone. That is, the ozone generator 80 is mounted on the housing 10. The ozone generator 80 uses a silent discharge, the discharge tube is a double glass tube with a spacing of several centimeters, and the tin foil (情) is applied and the wound coil is silently discharged by applying an alternating voltage of 5-25kV. When dry air is sent to one side, a part of oxygen is converted into ozone to produce a mixture of ozone and air with a content of about 10%, and the ozone has the effect of sterilization, deodorization and air purification. That is, the dry air that has passed through the dehumidifying member is purified by ozone generated in the ozone generator 80, and the air dehumidified and purified in the process includes the exhaust port 18 formed on the housing 10. Through the outside.

The conventional air purifier has been configured to purify the air using a filter. The method of purifying air using a filter has a problem in that the user is inconvenient to replace the filter regularly and the maintenance cost increases, but the air purification by the ozone generator 80 has the advantage that no filter replacement is required. .

In addition, in order to maintain a smooth flow of air in the housing 10, a transfer fan 23 is mounted between the dehumidifying member and the air purifying member, and the front suction port 14 is disposed on the cold sink 52. It is preferable that a plate-shaped blocking plate 60 is formed to block the air sucked in the upper portion from moving upward.

And, Figure 4 shows a second embodiment of the present invention, as shown in the figure, the width of the cold sink 52 is increased inclined downward from the upper side, the width of the heat sink 54 Decreases as it inclines from top to bottom. That is, the thermoelectric element plate 50 is not mounted vertically, but is mounted obliquely so that the upper portion of the cold sink 52 is narrow and the lower portion is wider. Correspondingly, the heat sink 54 has a lower portion and a wider portion. Therefore, the air flows naturally by the space that is wider in the direction of the air.

5 is a side cross-sectional view of the dehumidifier 100 according to the third embodiment of the present invention. Humid air sucked from the outside at the rear suction port 16 and the pair of side suction holes 15 is supplied to the cold sink 52 so that the rear suction port 16 and the cold sink 52 are separated from each other. An inlet pipe 90 is formed to communicate the upper part with each other, and a pair of side suction holes 15 and a connecting pipe 95 which communicates with the upper part of the cold sink 52 are further mounted to remove moisture. To prevent air from moving to the top.

In addition, the humidity of the air is controlled by the user's setting. The humidity sensor 30 is mounted in the upper space inside the housing 10 to measure the humidity of the air passing through the dehumidifying member. In addition, the control unit operates the dehumidifying member when air above the humidity set by the user is detected by the humidity sensor 30, and the operation of the dehumidifying member is stopped when the humidity measured by the humidity sensor 30 is less than or equal to a set value. However, the air purifying member is always operated while power is supplied.

Operation according to the above configuration of the present invention is as follows.

First, in the dehumidifier 100 of the present invention, the transfer fan 23, the exhaust port 18, and the ozone generator 80 are operated so that air is sucked from the lower suction ports 14, 15, and 18. The exhaust port 18 is discharged, and air is purified by ozone. After that, when a user sets a desired humidity rate using an operation panel connected to the control unit 70 and operates a dehumidifier, the control unit removes moisture while operating the thermoelectric element plate 50. That is, air containing moisture sucked from the suction ports 14, 15, and 18 is cooled to condensation below the dew point in the cold sink 52, and condensed dew droplets are condensed on the cold plate of the cold sink 52. The water droplets become larger and larger, and the generated droplets are collected in the water tank through the drain holes 19 by their own weight. The low temperature dry air passing through the cold sink 52 passes through the lower portion of the thermoelectric element plate 50 to the heat sink 54, and the low temperature dry air passing through the heat sink 54 is heated. And the same as the outside temperature. The air passing through the heat sink 54 is purified by ozone generated in the ozone generator 80, and the dehumidified and purified air is discharged to the outside through the exhaust port 18. The humidity of the air passing through 54 is measured by the humidity sensor 30, and the measured result is transmitted to the controller 70. The controller 70 continues when the measured humidity is equal to or higher than the humidity set by the user. To operate the dehumidifying member and to stop the operation of the dehumidifying member when the humidity of the set value is measured. However, even when the operation of the dehumidifying member is stopped, the humidity sensor 30 continuously measures the humidity and transmits it to the control unit 70. When the measured value is higher than the set humidity, the control unit 70 controls the dehumidification. The member is operated to remove moisture. By repeating this process, the user can keep the desired humidity continuously.

According to the above configuration and operation of the present invention, the moisture is removed using the thermoelectric element plate using the Peltier effect, which is environmentally friendly, and not only has a function of removing moisture, but also has a function of purifying air. The dehumidifier is commercially available, and it can also be dried in the space between the dehumidifier and the wall where mold is easily generated, and the effect of not having to replace the filter for air purification is generated.

What has been described above is merely an embodiment for carrying out the dehumidifier according to the present invention, and the present invention is not limited to the above-described embodiment, and the present invention may be applied without departing from the gist of the present invention as claimed in the following claims. Anyone with ordinary knowledge in the field of the present invention will have the technical idea of the present invention to the extent that various modifications can be made.
