Description

Dehumidifier {Dehumidifier}

The present invention relates to a dehumidifying apparatus, and more particularly, to a dehumidifying apparatus that can comfortably create an indoor environment by removing moisture from a room using natural energy at a low temperature.

Generally, indoors, ie living spaces, logistics spaces, and storage spaces, are heated in order to provide a suitable environment for human life or storage in winter, so that the temperature difference between the outside temperature and many differences Has In an environment where the temperature is higher than the outside, indoor air contains that much water vapor, and condensate forms on walls or glass, which are bordering the outside. Such condensate can corrode the storage and provide an environment in which mold and the like inhabit the room, thereby harming indoor hygiene and causing aesthetic damage. Therefore, in order to keep the indoor environment comfortable, there is a need for an apparatus for removing moisture in winter, which is a problem.

To date, many devices have been developed to control the temperature and humidity of the room to make the indoor environment comfortable and suitable for use. Among these devices, a lot of so-called air conditioners are generally supplied to control the temperature of the room by using evaporative heat of the refrigerant.

The air conditioner is composed of an indoor unit installed with an evaporator, which is an indoor heat exchanger, and an outdoor unit installed with a condenser, an outdoor heat exchanger, as is well known. It is a device to lower the indoor air temperature. That is, the air in the room undergoes a cycle in which the temperature of the room is lowered by passing the evaporator whose temperature is lowered while the refrigerant evaporates by the power of the blower and then circulating back to the room through the discharge port. Here, the moisture contained in the evaporator having a low temperature as the air passes through is condensed to form condensed water on the surface of the evaporator. This condensate is taken off the surface of the evaporator and collected in the drain pan, and then discharged to the outside through a hose or the like. Therefore, as a result, when the air conditioner is operated, the indoor air becomes low in humidity.

The air conditioner must be equipped with an indoor unit equipped with an evaporator and an outdoor unit equipped with a compressor and a condenser.

Since air conditioners are generally used to lower the indoor temperature in summer, they are not used in winter. However, when the refrigerant is circulated in the air conditioner in reverse, the air conditioner may also be operated as a heat pump, that is, a heater. When the air conditioner for both air conditioning and heating is operated as a heater in winter, particularly at temperatures below zero, frost is trapped on the surface of the condenser, which hinders heat exchange. In order to solve this problem, a method of circulating the refrigerant in the opposite direction for a while to remove the frost on the condenser surface and then undergo a cycle of cooling again. Such air-conditioning combined air-conditioners have a weak heating power, and in general, a heater that is heated by electricity is often installed on the upper side of the indoor unit.

As described above, the air conditioner must have an indoor unit and an outdoor unit in any form and at the same time have a complicated structure to circulate a cycle in which the refrigerant is compressed, condensed, and evaporated. Therefore, in order for the air conditioner to perform the dehumidification function, it is necessary to eventually perform the dehumidification operation through heat exchange by circulation of the refrigerant.

The present invention has been made to solve the above problems of the prior art, a dehumidification apparatus that can maintain the indoor environment comfortably by removing the humidity of the room using natural energy in the low temperature state without using any other energy The purpose is to provide.

Dehumidifier according to a first embodiment of the present invention is shown in Figures 1 to 3a. As shown in FIG. 1, the dehumidifier is installed in such a way that the case 10 contacts the outer wall 2. Of course, even the outer wall of glass or metal other than concrete is provided in contact with the back portion of the case 10. The case 10 has a discharge port 20a through which the indoor air circulated in the upper part is formed, and an inlet port 30a through which the indoor air is sucked in the lower part of the case 10. A plurality of louvers 20 and 30 are formed. Of course, a louver formed integrally with the case 10 may be used instead of the individual louvers 30 installed at the suction port 30a.

2 is a perspective view of a part cut to see the internal components of the dehumidifier, the case 10 is a front panel (10a), upper and lower panels (10b, 10d), and the rear surface is provided with a heat insulating material (10e) inside, respectively. The panel 10c includes a lower space part 11, a central space part 12, and an upper space part 13. The front panel 10a has a discharge port 20a at an upper portion thereof and a suction hole 30a at a lower portion thereof. Is formed, and the blower 200 is installed in the upper space portion 13 which is the lower portion of the upper panel 10b, and the condensed water is collected in the lower space portion 11 that is the upper portion of the lower panel 10d. It is to be discharged through. In addition, the condensation inducing means 100 provided in contact with the outer wall 2 is provided in the central space 12. The case 10 may be manufactured using a heat insulator in order to increase efficiency, or the case 10 may be manufactured from metal and a heat insulator may be installed therein. The important point is to configure the condensation induction means 100 to be insulated except for the rear part is installed. As shown in FIG. 3A, the back panel 10c of the case 10 does not have a panel because the condensation inducing means 100 directly contacting the outer wall 2 is installed in the central space 12. Therefore, the indoor air is circulated back through the intake port 30a, the lower space portion 11, the central space portion 12, the upper space portion 13, and the discharge port 20a. Here, the most important point is that the condensation inducing means 100 is installed in direct contact with the outer wall 2 in order to use the natural energy in the low temperature state of the outside air.

3A is a cross-sectional view of the dehumidifier, wherein the inner surface of the outer wall 2 is provided with a heat insulator 1, and the part where the dehumidifier is installed is not provided with a heat insulator, but a dehumidifier can be installed even where the heat insulator is installed. have. The case 10 of the dehumidifying device is attached to the outer wall 2, the case 10 may be fastened by various fastening means. A suction port 30a is formed between the lower panel 10d and the front panel 10a of the case 10, and a lower space part 11 is formed at the rear of the suction port 30a so that condensed water falls and collects. have. The condensation inducing means 100 is installed in the central space 12, and the condensation inducing means 100 is spaced apart from the base panel 103 and the base panel 103 which are fastened to the outer wall 2. The partition panel 101 is provided, and the partition panel 101 is formed with a plurality of pins 102 protruding to maximize the contact area with a predetermined interval on the side surface to induce the generation of condensate. Therefore, the air sucked from the lower portion of the condensation inducing means 100 is moved while contacting the base panel 103, the partition panel 101, and the fin 102, so that the heat exchange is made and then the upper space portion 13 Will be moved to. The condensation inducing means 100 preferably uses a material having a physical property capable of maintaining a temperature lower than the dew point temperature due to the rapid induction of cooling in taking low-temperature energy of the outside air. For example, a metal material is most suitable. In order to form condensed water, it is preferable to use metal materials such as aluminum, copper, and stainless steel, which have strong water resistance. The front surface of the condensation inducing means 100 is blocked by the front panel 10a, and the rear side thereof is provided to directly contact the outer wall 2. The upper space part 13, which is the upper portion of the condensation inducing means 100, is provided with a blower 200 connected to the motor 300. Blower 200 is suitable to use a blower with a low noise, as shown in Figure 6 motor 300 that provides power to the blower 200 is connected to the control unit 400, the bar is made, The control unit 400 is connected to the humidity sensor 500 may be controlled to maintain the appropriate humidity. As described above, the blower 200 is installed in the upper space portion 13, and a discharge port 20a through which heat exchange is performed to discharge dry air having a low humidity is formed on the front surface thereof, and the discharge port 20a is discharged. A plurality of louvers 20 are provided for controlling the direction of air. The louvers 20 may be installed in a form of horizontally stacked, or may be installed in a vertically stacked, or may be installed by mixing both.

When the dehumidifying apparatus according to the first embodiment of the present invention operates as described above, since the air blower 200 is rotated, indoor air has high humidity and high temperature in the air through the inlet port 30a. The space 11 is moved. The indoor air moved to the lower space 11 is moved to the upper condensation inducing means 100 while in contact with the base panel 103, the partition panel 101, and the fins 102. At this time, condensation induction is caused by the high temperature and high humidity of indoor air contacting the condensation induction means 100 which is maintained at a low temperature by the low temperature of the outside air and kept at a low temperature according to heat transfer with the outer wall. Condensate is formed on the surface of the means 100. This condensate falls to the lower space 11 by its own weight and is collected, and then discharged to the outside through the hose 40. After passing through the condensation inducing means 100, the temperature of the air is lowered and the humidity is lowered, and the dry air moves toward the discharge port 20a by the air pressure of the blower 200, and then is discharged into the room by the guidance of the plurality of louvers 20. By this operation, indoor air circulates inside the dehumidifier and gradually decreases indoor humidity. Since the blower 200 is controlled by the motor 300, when the room is degraded to a constant humidity, the controller 400 sends a signal to the motor 300 to stop the rotation of the blower 200 or to significantly reduce the speed. Maintain proper humidity.
