DEW CONDENSATION PREVENTION STRUCTURE OF AN ENTRANCE}

The present invention relates to an anti-condensation structure of the doorway, and in particular, the door frame forming the doorway to form a heat-conducting blocking hole to slow the rate of heat transfer or block heat transfer in the form of a long hole, and to insulate the inner and outer panels of the door The present invention relates to a condensation preventing structure of an entrance and exit that can prevent condensation caused by a significant temperature difference in an area of the entrance and exit by providing a member.

In general, when the temperature difference between the indoor and outdoor is remarkable, dew condensation occurs on the door frame or door corresponding to the indoor and outdoor boundary areas of the entrance and exit.

This condensation not only corrodes the door frame or door made of metal, but also forms a humid environment around the doorway, causing various foreign matters to be attached to the door frame or door, or mold fungi.

In order to solve this problem, the condensation preventing structure according to the prior art as shown in FIG. 6 is attached to a heat insulating member 2 such as a sponge on the door frame 1 corresponding to the indoor and outdoor boundary areas 4 of the entrance and exit. It was introduced between the door frame (1) and the door (3) to prevent condensation caused by contact between the cold and hot air in the interior (IN) and the outdoor (OUT) boundary area (4).

However, since the condensation preventing structure of the doorway according to the prior art is a structure that blocks the space formed between the door frame 1 and the door 3 to prevent cold and hot air from meeting, the door frame ( The door frame 1 corresponding to the interior (IN) and the exterior (OUT) boundary area 4 of the entrance and exit when the temperature of the outer part (part located at the outside) of 1) is cooled and the temperature of the inner part is increased. ) The problem of dew condensation on the surface could not be solved.

This problem has occurred because the door frame 1 is integrally formed and is greatly influenced by the temperature of the outdoor or the indoor space, and it has occurred because the means for blocking the heat transmitted through the door frame 1 was not provided. will be.

On the other hand, even in the door 3 forming the entrance and exit, the condensation phenomenon occurs at the contact part because the outer panel 3-1 and each engaging end 3-3 of the inner panel 3-2 are in direct contact with each other. There was this. That is, the coupling end 3-3 of the inner panel 3-2 heated by the indoor air and the coupling end 3-3 of the outer panel 3-1 cooled by the outdoor air are in direct contact with each other. As a result, a significant temperature difference occurs at the contact portion, causing condensation.

The present invention is devised to solve the problems of the prior art as described above, the technical problem of the present invention is that the door frame or the door itself at a position corresponding to the interior / exterior boundary area of the doorway is the indoor high temperature air and the outdoor low temperature The present invention provides a means for preventing condensation occurring in the interior / external boundary areas of the entrance and exit by preventing the boundary between the air and the air due to a significant temperature difference.

The present invention for solving the technical problem as described above is a doorway and a doorway formed by the door, a plurality of heat conduction blocking holes in the door frame of the area corresponding to the indoor and outdoor boundaries in succession to each other in the longitudinal direction, respectively, the thermal conduction At a position maintained at a constant distance from the blocking hole, a plurality of auxiliary heat conduction blocking holes are provided in the lengthwise direction to shift each other in succession to provide a condensation preventing structure of the entrance.

An auxiliary heat insulating member may be installed in the heat conduction blocking hole and the auxiliary heat conduction blocking hole, respectively.

On the other hand, the door frame corresponding to the outdoor side of the doorway is provided with a cover member perforated in the longitudinal direction so that the cover-side heat conduction blocking holes are shifted from each other, and the outer side of the cover member has an outer gasket contacting the door when the door is closed. The inner gasket is installed in the door frame corresponding to the interior side of the doorway, and a heat insulating member is installed between the outer panel connection end and the inner panel connection end of the door.

Such a condensation preventing structure is formed with a heat conduction blocking hole for blocking heat conduction in the inner / outer portion of the door frame formed integrally. Such a heat conduction blocking hole blocks the phenomenon that the door frame is cooled or heated to conduct its state.

That is, in the door frame and the door forming the doorway, when the outer portion of the door frame located on the outdoor side is gradually cooled from the outside to the inside by cold outside air, and the inside portion is heated from the inside to the outside by the hot air, Heat is blocked by heat conduction barriers.

In other words, heat conduction proceeds easily through objects as compared to air (space). Therefore, condensation due to the significant temperature difference is prevented by forming a blocking hole in the object to which the heat conduction proceeds so that a significant temperature difference is not generated at the boundary portion.

In addition, a heat insulating member is installed between the outer panel connection end and the inner panel connection end of the door constituting the doorway to block the heat conduction between the outer panel and the inner panel, thereby connecting the inner and outer panels in the area forming the interior and outdoor boundary at the doorway. Condensation will not occur in the stage.

When described in detail with reference to the accompanying drawings a preferred embodiment according to the present invention having such features as follows. Hereinafter, the doorway is a space formed by the door frame 10 and the door 20, and an area corresponding to an indoor and outdoor boundary means an area A where indoor air and outdoor air meet as shown in FIG. 2.

As illustrated in FIGS. 1 to 3, in the condensation preventing structure according to the present embodiment, a heat conduction blocking hole 12 and an auxiliary heat conduction blocking hole 14 are formed in the door frame 10 constituting the entrance and exit of the door 20. An insulating member 26 is installed between the outer panel connecting end 22 and the inner panel connecting end 24, and the cover member 30 having the cover side heat conduction blocking hole 32 perforated on the outer surface of the door frame 10. Is installed, the outer gasket 36 is installed on the outer surface of the cover member 30, the inner gasket 18 is installed inside the door frame 10.

Looking at this in more detail as follows.

The door frame 10 has a structure that is bent in multiple stages as shown in Figure 2, a plurality of heat conduction blocking holes as shown in Figure 1 in the stepped portion formed to be stepped toward the outdoor side in the door frame 10 ( 12) are drilled in succession in the longitudinal direction while being shifted from each other. At this time, the shape of the heat conduction blocking hole 12 is as follows. Width 7mm, length 50mm, space | interval 55mm between each heat conduction | blocking hole 12 is carried out.

That is, the heat conduction blocking holes 12 having the shape as described above are formed in a row, and another set of heat conduction blocking holes 12 are drilled on one side thereof so as to deviate from the heat conduction blocking holes 12. Although the shape of the heat conduction blocking hole 12 is formed in the form of a long hole in this embodiment, it is not limited thereto, and may be configured in a circular or polygonal shape.

Meanwhile, as shown in FIG. 2, in the indoor and outdoor boundary areas A, a plurality of auxiliary heat conduction blocks are provided inside the door frame 10 at a constant distance from the heat conduction blocking hole 12 formed to be close to the outdoor side. The ball 14 is drilled. The structure, the shape, and each arrangement are the same as those of the heat conduction blocking hole 12.

The cover member 30 which is bent to conform to the door frame 10 is installed in close contact with the outer surface of the door frame 10. The cover member 30 is also successively drilled in the longitudinal direction such that the cover side heat conduction blocking holes 32 are shifted from each other.

The outer gasket 36 is installed on the front surface of the cover member 30, and when the door 20 is closed, the outer gasket 36 is in close contact with the inner surface of the door 20 to improve the airtightness of the door 20 and improve the flow of air. Will be blocked.

The inner gasket 18 is installed on the inner side of the door frame 10, that is, the seating portion of the position close to the auxiliary heat conduction blocking hole 14, as shown in Figure 2, the inner side of the door when closing the door 20 In close contact with the shock absorber, the outer gasket 36 and the induction of air are blocked.

The heat insulating member 26 installed on the door 20 is installed between the outer panel connection end 22 and the inner panel connection end 24, and has a function of blocking heat conduction.

The inner gasket 18, the outer gasket 36, and the heat insulating member 26 may be formed of a material having a significantly lower thermal conductivity than metal such as synthetic resin, rubber, and silicon.

Referring to the operation of the present embodiment configured as described above are as follows.

When the heat conduction blocking hole 10 and the auxiliary heat conduction blocking hole 14 are formed in the indoor and outdoor boundary areas A of the door frame 10 forming the entrance and exit, respectively, the indoor side of the door frame 10 is formed by the hot air in the room. Even when heated, the conduction of the heat is blocked by the auxiliary heat conduction blocking hole 14, and the cooling phenomenon is blocked by the heat conduction blocking hole 12 even when the outdoor side of the door frame 10 is cooled by the outdoor cold air. .

For example, when a portion (object) of the interior side of the door frame 10 is heated as shown in FIG. 3, the heat is gradually lowered while heating the object in the direction of the arrow shown by dashed lines in FIG. 3. Is inverted. At this time, the heat reaching the auxiliary heat conduction blocking hole 14 is blocked by air (space) having a significantly lower thermal conductivity than the object (metal (material forming the door frame 10)) or bypasses the auxiliary heat conduction blocking hole 14. It is preached. Therefore, the conduction speed of the heat gradually moving to the lower temperature reaches the auxiliary heat conduction blocking hole 14 to be rapidly lowered or the heat conduction is stopped.

In addition, the heat which moves to the side with a low temperature through the object (part of the door frame 10) between each auxiliary heat conduction blocking hole 14 is another auxiliary heat conduction blocking hole 14 which shifts | deviates from the original auxiliary heat conduction blocking hole 14 ), The conduction speed is significantly slowed down or the heat conduction is cut off.

On the other hand, the movement of heat as described above is blocked or remarkably slow even in the periphery of each heat conduction blocking hole 12 formed at the outdoor side with respect to the boundary area A between the indoor and the outdoor. That is, when the door frame 10 located on the outdoor side is cooled, the cooling action is gradually progressed to the indoor side as shown by the arrow shown in solid line in FIG. 3, wherein the cooling progresses while passing through the respective heat conduction blocking holes 12. It will be stopped or markedly slow.

This action prevents a significant temperature difference from occurring in the boundary area A of the entrance and exit. That is, when the indoor hot air (heat) is gradually conducted to the boundary area (A) while heating the door frame 10, it is prevented or moved slowly by each auxiliary heat conduction blocking hole 14 to be conducted in a state where the temperature is lowered. When the outdoor side cool air is gradually moved to the boundary area A while cooling the door frame 10, it is blocked by each heat conduction blocking hole 12, or the cooling progress speed thereof is remarkably slowed, so that the inside of the boundary area A is slow. In this case, the high temperature is maintained.

Therefore, the door frame 10 of the boundary area A has similar temperatures which do not differ greatly, and condensation due to a significant difference in temperature is prevented. That is, the heat of the indoor side passes through the auxiliary heat conduction blocking hole 14 to a temperature lower than the temperature of the indoor door frame 10, and the outdoor low temperature passes through the heat conduction blocking hole 12. Since the temperature is higher than the temperature of), no temperature difference occurs at the boundary or a slight difference does not cause condensation at the boundary.

In addition, since the cover member 30 is installed in close contact with the outer surface of the door frame 10, it is possible to minimize or prevent the phenomenon that the outer side of the door frame 10 is cooled by the outdoor side cold air.

In addition, the cover side heat conduction blocking hole 32 formed in the cover member 30 has a function of slowing or blocking heat conduction, as described above with the heat conduction blocking hole 12 and the auxiliary heat conduction blocking hole 14.

The outer gasket 36 installed on the front surface of the cover member 30 not only prevents cool external air from flowing between the door frame 10 and the door 20, but also closes the door 20 when the door 20 is closed. It may be in contact with the inner side (inner side of the multi-folded outer panel) of the shock absorber.

In addition to the outer gasket 36, the inner gasket 18 installed on the door frame 10 is in close contact with the door 20 when the door 20 is closed to cushion shocks, and at the same time, the hot air inside the door frame ( It prevents the phenomenon flowing between the 10) and the door 20.

In this way, by preventing hot air or cold air from flowing between the door frame 10 and the door 20, condensation caused by hot air and cold air in the boundary area A is prevented.

On the other hand, the heat insulating member 26 is installed at the coupling portion between the outer panel connection end 22 and the inner panel connection end 24 of the door 20. In other words, a synthetic resin, a rubber material, a heat insulating material, or the like, having a significantly lower thermal conductivity than metal is provided between the connection ends 22 and 24. Therefore, the inner panel and the outer panel itself of the door 20 is heated or cooled to prevent the phenomenon of forming a boundary with a remarkable temperature difference at the coupling portion to prevent condensation.

4 of the accompanying drawings shows another embodiment of the present invention.

As illustrated in FIG. 4, the condensation preventing structure according to another embodiment has a configuration in which auxiliary heat insulating members 50 are inserted into the heat conduction blocking holes 12 and the auxiliary heat conduction blocking holes 14, respectively.

In this way, by installing the auxiliary heat insulating member 50 having a significantly lower thermal conductivity than the metal in the heat conduction blocking hole 12 and the auxiliary heat conduction blocking hole 14, the heat conduction blocking hole 12 and the auxiliary heat conduction blocking hole ( 14) The conduction of heat through the area is impeded or its speed is significantly slower. In addition, the auxiliary heat insulating member 50 has a function of closing the open heat conduction blocking hole 12 and the auxiliary heat conduction blocking hole 14 to prevent the insertion of foreign substances and at the same time absorbing noise due to impact.

Meanwhile, in the accompanying drawings, as illustrated in FIG. 5, in the condensation preventing structure according to another embodiment, a plurality of heat conduction blocking pins 17 are disposed between each other on the door frame 10 in a region corresponding to an indoor and outdoor boundary. Spaces are formed at regular intervals so as to form a space, and a plurality of auxiliary heat conduction blocking pins 19 are formed in the door frame 10 at a predetermined distance from the heat conduction blocking pins 17. They are formed at regular intervals as much as possible.

As described above, since the heat conduction blocking pin 17 and the auxiliary heat conduction blocking pin 19 are formed in the door frame 10 corresponding to the boundary area A, the high temperature is low and the low temperature is low. It becomes high, and condensation phenomenon by the remarkable temperature difference in the boundary area A can be prevented.

For example, when indoor air heats a part of the door frame 10, the heat moves from inside to inside through a part of the door frame 10, but must pass through each auxiliary heat conduction blocking pin 17. The conduction rate is significantly slowed down, and the heat conducting in the process is cooled, and condensation due to a significant difference in temperature is prevented because heat in a state where the temperature is cooled down reaches the boundary region A. .

On the other hand, although not shown, instead of each of the heat conduction blocking pin 17 or the auxiliary heat conduction blocking pin 19 may be bent in a zigzag region to significantly slow the speed of heat conduction. Such a zigzag section slows the conduction of heat, slows the conduction time to the destination, and raises the temperature (raises the heat conducted from the outside) or lowers (descends the heat conducted from the inside of the room). A significant temperature difference does not occur in A), thereby minimizing or preventing condensation occurring in the boundary area A. FIG.

The condensation prevention structure of the entrance and exit according to the present invention forms a heat conduction blocking hole in the boundary area when the door frame itself is cooled, heated and conducted by indoor or outdoor temperature, thereby preventing conduction or significantly slowing down the speed of the entrance. It is possible to minimize or prevent condensation due to a significant temperature difference in the door frame itself corresponding to the boundary area, and to prevent the door frame from being cooled or heated by the outdoor temperature by the cover member, and to the outer gasket and the inner gasket. Air is prevented from entering between the door frame and the door, and a heat insulating member is installed between the inner and outer panels of the door to prevent condensation from occurring at the contact portion of each door.
