Door frame with built-in heating means {DOOR FRAME HAVING HEAT DEVICE}

The present invention relates to a door frame with a built-in heat generating means, and more particularly to a door frame with a heat generating means provided with a heat generating means inside the door frame to suppress the occurrence of condensation in the door and the door frame. .

Buildings such as apartments or houses, as well as various office buildings, are divided into a plurality of compartments according to the purpose of designing, and each compartment is provided with a door for the convenience of the user's access. In particular, steel doors or fire doors are mainly used for spaces provided for entrances and entrances to buildings or dedicated purposes (eg, outdoor unit installation for air conditioning equipment).

A fire door is a kind of door designed to prevent the transfer of flames between each compartment in case of fire or to delay the time of flame transfer and to make the evacuation time for the user, and the fire itself should not be lost due to the fire. It is mainly made of iron metal material.

In general, most doors including fire doors (hereinafter referred to as 'doors') are installed to open and close the open area of the door frame constructed at the edge of the entrance provided on the wall of the compartment. That is, when the door is closed, the edge of the door is in contact with the inner end of the door frame to provide effects such as insulation and soundproofing indoors and outdoors, and enables the user's access as the door is opened.

Often, the door is rotatably connected by a hinge at one side of the door frame, and the other side of the door frame is locked or unlocked in close contact with the door frame. In particular, in a state in which the door is closed, it is common to provide a stepped structure at the facing portion of the door frame that is in contact with the closed door so that the door can be pressed closer to the door frame. In this case, the stepped structure refers to a contact supporting groove provided in advance in a facing portion of the door frame to fit a door having various sizes and shapes.

In the conventional door and the door frame, as shown in FIG. 1, when the door 10 is closed, the side end 11 of the door 10 is in contact with the step 21 provided at the facing portion of the door frame 20. Had a form.

In particular, the stepped portion 21 of the door frame 20 is further provided with a gasket 23 protruding toward the door 10 side. The gasket 23 has elasticity to provide a function of alleviating an impact between the door frame 20 when the door 10 is closed. In addition, the gasket 23 seals the space between the closed door 10 and the door frame 20 to improve the indoor insulation effect. A gasket insertion groove 21a is provided in a step 21 portion of the door frame 20 in which the gasket 23 is provided, and the gasket insertion groove 21a is provided from the step 21 of the door frame 20 to the door 10. It is formed by inwardly into the bending protrusion 22 protruding toward).

However, the above-described conventional door frame 20 is composed of a cross section of the entire section is made of steel metal. In other words, in the conventional door frame 20, the outdoor exposure cross section 20a and the indoor exposure cross section 20b were connected to each other. As a result, the outdoor cold air that influenced the outdoor exposed cross section 20a was directly transferred to the indoor exposed cross section 20b. As a result, condensation was generated in the indoor exposed cross-sectional section 20b installed in a room having a relatively high temperature compared to the outdoor.

Here, the dew condensation is a boundary surface where the air of the relatively high temperature and humidity is cool when the temperature difference between the two spaces (that is, the interior and the outside) becomes more than a predetermined range with a boundary (that is, a door) interposed between the spaces. It refers to a phenomenon that generates dew when it hits.

This condensation can easily be detected, especially in winter, especially when heating indoors. Dew generated through the door or door frame flows to the floor and contaminates the indoor environment or damages the exterior surface, damaging the appearance. . In particular, when the door or the door frame is made of a steel metal material, corrosion of the material may proceed quickly, and if left as it is, the opening and closing noise of the door may be generated or the door may not be smoothly opened and closed. .

To this end, the door frame 20 is maintained at a set temperature, as well as enabling heat transfer to the door 10, so as to prevent the occurrence of condensation along the door and the door frame. Attention is rising.

In this arrangement structure, the high temperature heat generated by the heat generating means 170 is primarily transferred to the door frame 100 and heated, and secondly, toward the door 200 facing the heated door frame 100. Since heat transfer can also be made, it is possible to prevent condensation occurring in the door frame 100 and condensation occurring in the door 200 at the same time.

On the other hand, the heat generating means (171, 172) may be installed inside the cross section of the door frame 100 in contact with the interior space, which is the site where condensation occurs mainly. In this case, since the interior door frame surface portion where the dew condensation is mainly generated is directly heated, more effective prevention of the interior door frame surface condensation is possible than the heat generating means 170.

Here, as a specific example that can be used as the heat generating means 170, 171, 172, it may be a tube (hereinafter, referred to as a 'constant temperature wire tube') member wound a heating cable (heating cable). In addition, any form of heat generation means capable of generating heat by receiving power may be used.

In addition, although the cross-sectional shape of the heat generating means 170 is illustrated as having a rectangular rectangular cross section, such a shape does not limit the present invention and may be modified in various embodiments.

The constant temperature wire as the heat generating means 170 may be manufactured using nichrome wire, aluminum, carbon, ceramic series, or the like as a material that generates heat at a temperature set through electrical resistance.

On the other hand, in order to implement the heat generating function by the heat generating means 170 may include a power supply means 180 for supplying power to the heat generating means 170, and further to adjust the power supplied to the heat generating means 170 In order to control the operation of the power supply means 180, the operation control means 190, that is, a switch may be further included.

The second section frame 130 represents the remaining section of the door frame 100 connected from the first section frame 110 and exposed toward the interior. The gasket 136 may be installed in the second section frame 130 by using the insertion groove 132, and the gasket 136 supports the interior outer end of the door (200 in FIG. 2). In addition, the gasket 136 has a predetermined elasticity, has a function of absorbing the shock generated when the door (200 in FIG. 2) is closed, and is in close contact with the door in a closed state to secure an indoor insulation effect. To make it work.

In particular, the heat generating means 170 is disposed in contact with the inner wall surface of the door frame 100. This is to effectively heat transfer to the side of the door (200 of FIG. 2), as well as heating the door frame 100 through the heating control of the heat generating means 170. The overall appearance of the door frame 100 can be confirmed in more detail by referring to the perspective view of FIG.

On the other hand, in the section in which the first section frame 110 and the second section frame 130 is installed on the wall (W), the coupling frame 140 may be padded and combined. The coupling frame 140 is configured to firmly fix the door frame 100 to the wall. In particular, the first section frame 110 and the second section frame 130 constituting the door frame 100 does not open or deform each other to improve durability.

And inside the cross section of the door frame 100 is filled with the door frame interior material 101, which is a flame retardant or thermal insulation functional material of the same or similar form as the door interior material 201 described above. Mainly polyester material may be used, and in addition, various materials such as glass wool or polyurethane may be used.

As described above, according to the present invention, it is possible to solve the inconvenience of condensation generated in the door as well as the door frame installed on the boundary due to the occurrence of the temperature difference in the indoor and outdoor. In particular, when the position of the heat generating means built in the door frame is placed close to the door facing, the heat transfer from the heat generated door frame to the door can be made quickly.

In addition, according to the present invention, it is possible to use a constant temperature wire that generates heat at a temperature set by the application of power as a heat generating means, which is inserted into the frame in the longitudinal direction of the door frame so as not to impair the appearance aesthetics.
