Description
Technical Field
The present invention relates to a dehumidifier, and more particularly, to a novel dehumidifier for a control panel (dehumidifying device) which is mounted on an outer surface of a control panel, can effectively remove moisture generated in the control panel, and can prevent inflow of foreign substances into the control panel.
background
Generally, a control panel is equipment for controlling operations of various electronic devices and manufacturing apparatuses, in which various circuit components and controllers are built.
In such a control panel, the control panel used for controlling the operation of the industrial manufacturing apparatus is installed in a work place where the manufacturing apparatus is installed, and thus is greatly affected by the environment in the work place.
That is, since the conventional control panel incorporates various circuit components, it is very sensitive to the influence of moisture, and the operation is frequently abnormal or damaged due to various dusts, oils, and the like generated in the manufacturing process, so that there are problems that a failure frequently occurs in the industrial control panel under severe environmental conditions and that a fire is highly likely to occur due to a short circuit.
Therefore, it is common to provide various types of dehumidifying apparatuses so that it can safely protect a control panel placed at a work site from moisture, and prevent the above-mentioned problems of damage to the inside of the control panel due to moisture or abnormal operation from occurring by a dehumidifying operation of the dehumidifying apparatus. This is disclosed in, for example, granted patent No. 10-0544563, granted utility model No. 20-0347614, and granted patent No. 10-0424345.
However, the dehumidifying apparatus according to the related art is configured to be located in a control panel to remove moisture in the control panel, so that high-temperature hot air heated for dehumidification can be supplied only to the control panel, and various circuit components in the control panel are damaged or abnormally operated by the high-temperature hot air.
Of course, in recent years, as disclosed in granted patent nos. 10 to 0781347 and 10 to 0473193, etc., a technique of mounting a dehumidifying apparatus on an outer wall surface of a control panel is provided, so that it is possible to prevent circuit components in the control panel from being damaged due to high-temperature hot air released from the dehumidifying apparatus.
However, the above-described technique has a problem that the dehumidification function cannot be effectively performed because of lack of design in consideration of the flow characteristics of the air. In particular, since various dusts, oils, and the like existing in a work site cannot be sufficiently handled, a phenomenon occurs in which the dehumidifier is easily broken down by the influence of the inside of the work site, and thus it is difficult to apply the dehumidifier to a small-sized control panel of a manufacturing plant having severe conditions.

Detailed Description
Hereinafter, a preferred embodiment of the dehumidifying apparatus for a control panel according to the present invention will be described with reference to the attached fig. 1 to 4.

At this time, in order to explain the internal structure, the perspective views in the above-described respective drawings are illustrated with one side wall of the case removed.
As shown in these drawings, a dehumidifying apparatus for a control panel according to an embodiment of the present invention generally includes: a case 100, a partition wall 200, a thermoelectric module, and a guide plate 400. In particular, the dehumidifying apparatus for a control panel according to the embodiment of the present invention is mounted on the outer surface of the control panel 10, and can effectively remove moisture generated in the control panel 10 and prevent foreign materials from flowing into the inside.
This will be described in more detail for each structure.
First, the case 100 is a portion forming the external appearance of the dehumidifying apparatus for a control panel according to the embodiment of the present invention.
The case 100 is formed as a box having respective wall surfaces. In this case, the wall surfaces of the housing 100 are assembled and coupled to each other, and preferably, one of the wall surfaces may be opened and closed for maintenance.
In particular, the front portion 110 of the housing 100 is fixed to the outer surface of the control panel 10. The outer surface of the control panel 10 to which the housing 100 is attached means a surface on which the outlet hole 11 and the inlet hole 12 are formed for air circulation in the control panel 10.
In addition, the front surface 110 of the housing 100 is formed with two communication holes 111, 112 spaced up and down to communicate with the internal space of the control panel 10, wherein the positions of the two communication holes 111, 112 are: one of the communication holes (the communication hole located on the lower side in the drawing) (hereinafter referred to as "the inflow-side communication hole") 111 communicates with the outflow hole 11 (see fig. 4) outside the control panel 10, and the other communication hole (the communication hole located on the upper side in the drawing) (hereinafter referred to as "the outflow-side communication hole") 112 communicates with the inflow hole 12 outside the control panel 10. That is, the air in the control panel 10 flows into the housing 100 through the outflow hole 11 and the inflow communication hole 111 in order, and is supplied into the control panel 10 through the outflow communication hole 112 and the inflow hole 12 in order.
At this time, at least one communication hole 112 of the two communication holes 111 and 112 further includes a first exhaust fan 113. The embodiment of the present invention is described by taking the case where the outlet hole 11 is provided with the first exhaust fan 113.
An air inlet 121 through which external air (indoor air) of the dehumidifying apparatus is sucked is formed in the rear surface 120 of the casing 100, and an air outlet 131 is formed in the upper surface 130 of the casing 100 so that air introduced through the air inlet 121 is discharged.
That is, the air in the room flows into the case 100 through the air inlet 121 and is then discharged into the room through the air outlet 131.
At this time, at least one of the air inlet 121 and the air outlet 131 is provided with second exhaust fans 122 and 132 for forcibly sucking indoor air or forcibly exhausting high-temperature air in the case 100. In an embodiment of the present invention, the second exhaust fans 122 and 132 are provided at both the air inlet 121 and the air outlet 131, so that high-temperature hot air in the casing 100 is exhausted as smoothly as possible.
further, a condensed water discharge hole 141 is formed to penetrate through the rear side of the bottom surface 140 of the case 100, and the bottom surface 140 of the case 100 is formed to be gradually inclined downward toward a rear side portion where the condensed water discharge hole 141 is formed. That is, condensed water condensed and dropped at a heat absorption side portion of the thermoelectric module 300, which will be described later, is allowed to flow into the rear side along the inclination of the bottom surface portion of the case 100, and then is discharged to the outside through the condensed water discharge hole 141. In this case, a condensed water discharge hose (not shown) is connected to the condensed water discharge hole 141 so as to guide the discharge of condensed water.
In addition, in the embodiment of the present invention, the air inlet 121 of the housing 100 further includes a filter 123.
That is, in consideration of the fact that the dehumidifying apparatus for a control panel according to the embodiment of the present invention is mainly installed in a work site equipped with a processing machine such as a machine tool, and dust, oil, iron powder, etc. generated in the work site flow into the casing 100, the air inlet 121 further includes a filter 123 for filtering out dust, oil, and foreign substances from air sucked through the air inlet 121.
In the rear surface portion 120 of the housing 100, a guide pipe 124 for guiding air to flow upward from the bottom and be sucked into the air inlet 121 is further provided at a portion where the air inlet 121 is located.
That is, even if the air inlet 121 is provided with the filter 123, if the filter 123 is configured to directly receive air in a working site, the filter 123 is directly affected by iron powder, dust, and oil contained in the air, and a clogging phenomenon occurs, and thus high-temperature air in the casing 100 may not be smoothly discharged. Therefore, the draft tube 123 is additionally provided, and the draft tube 123 is formed to have an open bottom structure, so that iron powder, oil, and the like can be naturally dropped while the air in the working site is moving up and down along the draft tube 124, and the problems of pollution, damage, and the like caused by direct exposure of the filter 123 to the working environment can be solved.
In addition, the embodiment of the present invention additionally provides that the upper surface 130 of the housing 100 further has a shielding film 133 at a position where the exhaust port 131 is located, for preventing dust or foreign matter from falling into the exhaust port 131 and guiding the exhaust flow of air.
That is, since the upper surface 130 of the housing 100 is formed with the exhaust port 131, the reverse inflow of the dust, oil, and iron powder through the exhaust port 131 can be prevented by additionally providing the shielding film 133 for protecting the exhaust port 131 in consideration of the possibility that various kinds of dust, oil, iron powder, and the like floating in the work site are accumulated in the exhaust port 131.
Next, the partition wall 200 is configured to divide the interior of the housing 100 into two spaces, a lower space and an upper space.
That is, according to the partition wall 200, the lower space in the casing 100 constitutes a heat-absorbing space where the two communication holes 111 and 112 are located, and the upper space in the casing 100 constitutes a heat-radiating space where the intake port 121 and the exhaust port 131 are located.
The partition wall 200 is located substantially at the center of the casing 100 and is provided to block a heat-absorbing space and a heat-dissipating space inside the casing 100.
In the embodiment of the present invention, it is particularly proposed that the partition wall 200 is inclined so as to be inclined upward toward the front. This mounting structure of the partition wall 200 takes into consideration the flow characteristics of air. That is, the air flowing into the heat radiating space through the air inlet 121 is moved upward by the inclination of the partition wall 200, and is smoothly discharged through the air outlet 131; the air flowing into the heat-absorbing space through the inflow passage 111 is guided by the inclination of the partition wall 200, and can be smoothly discharged through the outflow passage 112.
In the embodiment of the present invention, the partition wall 200 is formed of a Heat insulating structure, so that it is possible to prevent a phenomenon in which the dehumidifying performance is deteriorated due to the high-temperature hot air (Heat) in the Heat radiating side space being transferred to the Heat absorbing side space and the high-temperature hot air being supplied into the control panel 10. Such a heat insulating structure of the partition wall 200 may be implemented in various ways, and in the embodiment of the present invention, a heat insulating material may be additionally provided on the surface of the partition wall 200, or the entire partition wall 200 may be made of a heat insulating material.
A mounting hole 210 is formed through the center (center) of the partition wall 200. In this case, the mounting hole 210 is configured to mount a thermoelectric module 300, which will be described later.
next, the thermoelectric module 300 is a functional member that absorbs and radiates heat from air flowing through each space in the case 100, and is mounted in the mounting hole 210 of the partition wall 200 such that a heat radiation side portion is exposed to the heat radiation side space and a heat absorption side portion is exposed to the heat absorption side space.
Such a thermoelectric module 300 includes: a heat absorbing absorber plate (heat absorption plate) 310; a heat dissipating plate (heat dissipating plate)320 spaced apart from the heat absorbing plate 310 to dissipate heat; and a thermoelectric element part (thermoelectric part)330 disposed between the heat absorbing plate 310 and the heat dissipating plate 320, and configured to perform an endothermic reaction on the heat absorbing plate 310 by supplying power thereto.
The heat absorbing plate 310 is disposed to be exposed to a heat absorbing side space in the case 100, and the heat dissipating plate 320 is disposed to be exposed to a heat dissipating side space in the case 100.
in particular, the plates 310 and 320 are provided with heat radiating fins 311 and 321, respectively, for improving heat exchange performance.
the thermoelectric element part 330 is composed of a thermoelectric element having an N-type semiconductor (N-type thermal electric element) and a P-type semiconductor (P-type thermal electric element)332 disposed to allow the heat absorbing plate 310 to perform an endothermic reaction according to power supply.
Next, the guide plate 400 is configured to vertically partition a space in which the two communication holes 111 and 112 are formed in the heat absorption side space in the housing 100, so as to prevent the air in the control panel 10, which flows into the housing 100 through the inflow side communication hole 111, from directly flowing through the outflow side communication hole 112 and being directly discharged.
That is, by additionally providing the guide plate 400, the air flowing into the case 100 through the inflow side communication hole 111 in the control panel 10 is completely passed through the heat absorbing plate 310 and the heat dissipating fins 311 of the thermoelectric module 300 mounted on the partition wall 200, and after heat exchange and dehumidification, the air can flow out into the control panel 10 through the outflow side communication hole 112.
The guide plate 400 is formed as a flat plate, and is provided such that a front end thereof is fixedly attached to an inner wall surface of a front portion of the housing 100 and a rear end thereof faces an inner wall surface of a rear portion of the housing 100.
At this time, the guide plate 400 is formed to have a front and rear length smaller than a distance between the front surface 110 and the rear surface 120 in the case 100 so that the rear end of the guide plate 400 can be spaced apart from the rear surface 120 in the case 100, and the air flowing in from the inlet-side communication holes 111 completely passes through the heat dissipation fins 311 attached to the heat absorbing plate 310 of the thermoelectric module 300 and then flows to the portion formed by the outlet-side communication holes 112 through the open portion formed by the spaced structure, and finally flows out.
of course, although not shown in the drawings, the guide plate 400 may be constructed in the following manner. That is, the guide plate 400 is formed such that the rear end thereof extends to the inner wall of the rear portion of the housing 100, but a separate opening portion such as an opening hole is additionally formed at the rear side portion of the guide plate 400, so that the same function as that of the previous embodiment is accomplished.
in addition, an embodiment of the present invention additionally provides that the interior of the casing 100 further includes: and a controller 500 for controlling the operation of the thermoelectric module 300 and the operation of the exhaust fans 113, 122, and 132.
At this time, although the controller 500 may be affected by the high-temperature hot air, it is installed in the heat-radiating side space within the case 100, and thus does not affect the flow of air for dehumidifying the control panel 10.
The unexplained reference numeral 510 is a temperature sensor, and the controller 500 is programmed to automatically perform the operation control of the thermoelectric module 300 and the operation control of the respective exhaust fans 113, 122, 132 based on the temperature information sensed by the temperature sensor 510.
Of course, the controller 500 may be configured to be disposed in the control panel 10, as shown in fig. 8 to 10, which has an advantage that the overall size of the dehumidifying apparatus can be minimized.
Hereinafter, the dehumidifying process of the control panel 10 using the dehumidifying apparatus for a control panel according to the embodiment of the present invention will be described in more detail.
First, when a dehumidifying operation of the control panel 10 is required, the controller 500 performs operation control of supplying power to the thermoelectric module 300 and supplying power to the respective exhaust fans 113, 122, 132.
When the thermoelectric module 300 is supplied with power, a direct current is supplied from the N-type semiconductor 331 to the P-type semiconductor 332, so that the heat absorbing plate 310 and the heat radiating fins 311 provided therein absorb heat existing in the heat absorbing-side space in the case 100, and the heat is released to the heat radiating-side space in the case 100 through the heat radiating plate 320 and the heat radiating fins 321 provided therein.
Then, due to the operation of the first exhaust fan 113, the air in the control panel 10 flows into the heat absorption side space in the casing 100 through the inflow side communication hole 111, flows to the rear side of the heat absorption side space under the guide of the guide plate 400, and is resupplied to the inside of the control panel 10 through the outflow side communication hole 112 under the guide of the partition wall 200. In this process, the air is dehumidified while exchanging heat with the heat absorbing plate 310 and the heat radiating fins 311 provided therein. At this time, the moisture separated from the air is condensed and condensed by the heat radiating fins 311, and the condensed water formed thereby flows backward by the inclination of the partition wall 200 and falls on the bottom surface portion 140 of the case 200, and is then discharged to the outside of the case through the condensed water discharge hole 141 formed in the bottom surface portion 140.
Further, by the operation of the two second exhaust fans 122 and 132, air inside the work site flows into the space on the heat radiation side in the casing 100 through the air inlet 121, and is discharged to the room through the air outlet 131. In this process, the air exchanges heat with the heat sink 320 and the heat dissipation fins 321 provided therein, and the heat is dissipated from the inside of the heat dissipation side space. In this case, it is considered that the air inlet 121 is provided with the filter 123 and the draft tube 124, and various dusts, iron powders, and oil components inside the work site are primarily filtered while flowing upward along the draft tube 124, and secondarily filtered while passing through the filter 123, thereby preventing the contamination of the inside of the case 100. Furthermore, since the exhaust port 131 is covered by the shielding film 133, dust, oil, and the like floating inside the work site are prevented from flowing into the space inside the housing 100 through the exhaust port 131.
Also, as the above-described operations are repeatedly performed, hot air generated by each electrical component inside the control panel 10 is supplied to the dehumidifying apparatus according to the embodiment of the present invention to be dehumidified and cooled, and the dehumidified and cooled low-temperature dry air is resupplied to the inside of the control panel 10, thereby radiating the electrical component.
in general, with the dehumidifying apparatus according to the present invention, it is possible to prevent the occurrence of abnormal operation or malfunction of each electrical component of the control panel 10 due to high temperature and high humidity, and particularly, by the inclined installation structure of the partition wall 200 or the arrangement structure of the air inlet 121 and the air outlet 131 and each communication hole 113, 122, 132 and the arrangement structure of the guide plate 400, the air flow is smooth, the heat exchange performance with each heat radiating fin 311, 321 can be maximized, and the dehumidifying performance can be improved.
further, according to the dehumidifier of the present invention, the foreign matter such as various kinds of dust, iron powder, oil, etc. existing in the air inside the work site is prevented from flowing in, and damage by the foreign matter can be prevented.
