Heat Exchanger Support Bracket for Ceiling Air Conditioner {HEAT EXCHANGER SUPPORTING BRACKET FOR CEILING AIR CONDITIONER}

The present invention relates to a bracket for fixing a ceiling-type air conditioner, and more particularly, to a sliding bracket structure made of stainless steel that can replace an existing iron-type bracket when washing and cleaning a number of installed ceiling-type air conditioners. .

In general, a heat exchanger is a device that absorbs heat from one side and radiates heat to the other side in a space region with a temperature difference. In the case of absorbing hot air and discharging hot air into the room, it acts as a heating system. Basically, the cooling system consists of a compressor that compresses the injected refrigerant into a high-temperature and high-pressure gaseous state, a condenser that condenses the gaseous refrigerant and releases heat to the outside, and a low-temperature and low-pressure It is composed of an expansion valve that makes liquid refrigerant and supplies an appropriate amount of refrigerant to the evaporator, and an evaporator that absorbs heat from the surroundings while vaporizing. That is, an actual cooling action occurs by the evaporator in which the liquid refrigerant absorbs the amount of heat equivalent to the heat of vaporization from the surroundings, and the refrigerant flow cycle through the compressor, the condenser, the expansion valve, and the evaporator is repeatedly performed.

A general structure of a conventional conventional ceiling system air conditioner according to the refrigeration cycle and a structure of a heat exchanger support bracket installation will be briefly described with reference to FIGS. 1 and 2 . 1 is a one-view view of Korean Patent Registration No. 10-1195563, and is cited to explain the general internal configuration of a ceiling air conditioner.

1, inside the casing, the heat exchanger is installed between the fan and the outer side wall of the casing in the vertical direction in a substantially rectangular fence shape from the central axis where the motor and the fan are installed to the outer peripheral surface outward.

When installing a general ceiling-type air conditioner, a driving motor 22 and a blower fan 21 are installed in the center of the ceiling inside the casing 10, and a heat exchanger ( 30) is provided, and a drain pan 50 is provided at the lower portion of the heat exchanger 30 to accommodate the bottom surface of the heat exchanger 30, and to store condensed water flowing to the outer surface of the heat exchanger, and has an open ceiling. A casing front cover 70 sealing the inside of the casing is attached.

Since the present invention relates to a bracket for supporting a heat exchanger in a state in which a drain fan, a blower fan, and a motor are not installed or disassembled in such a ceiling air conditioner structure, the prior art will be limitedly described as follows. 2 is a photograph showing one state of installing a bracket for supporting a heat exchanger in the internal shape of a spherical ceiling air conditioner of a model before 2010.

As shown in Figure 2, the fixed housing 10, the ceiling 11 and the housing inner wall 12 to the inside by a predetermined distance to the inside of the heat exchanger 30, the lower support surface installed using a bracket (20) The structure in which the heat exchanger 30 is fixed inside the housing 10 by screw coupling is a common appearance in most existing air conditioners.

In this case, it can be seen from the drawing that the brackets 20 are arranged at equal intervals in the height direction of the ceiling of the housing 10 from the center of each of the four sides. During fixed use, there was a problem of condensate discharge and severe rusting and wear as shown in the picture in a humid environment. In particular, when the lower end of the support bracket 20 surrounding the bottom surface of the heat exchanger 30 that is submerged in the stored condensate is made of iron, rust and wear conditions are serious, and measures for improvement are urgently needed.

The wear caused by rust causes not only the discharge of harmful substances, but also the strength of the support for supporting the heat exchanger is weakened, significantly lowering the bearing capacity and, in severe cases, breaking, causing a serious problem that the heat exchanger, an essential component of the housing, can fall to the bottom. There was also a big problem in performing the original role of the bracket, which is a fixed support.

The problem is that the condensed water generated during cooling flows down to the surface of the heat exchanger, and the steel material installed along the outer wall of the heat exchanger is exposed to such condensed water as it is, so there is a big problem of corrosion due to oxidation in wet conditions. it was

In general, air conditioners generate contamination from the point of operation after installation. In principle, condensed water is generated on the cooling fins in the process of sucking indoor air, cooling it instantaneously, and blowing cool air again. It accumulates on the surface, and this environment is soon becoming an optimal place for bacterial growth, and since it can be fatal to health, such as causing respiratory diseases in the elderly and young children with weak immunity, decomposition, sterilization and cleaning of the air conditioner must be carried out regularly. In the case of such a bracket made of iron, when the surface is exposed to condensate, it rusts due to oxidation and a large amount of harmful components are generated.

In particular, as it is operated for cooling in summer, the surface of the steel bracket is severely corroded by the condensate that accumulates at a certain height to cause rust. This phenomenon cannot be recognized and dealt with unless the air conditioner is disassembled. There was a problem that grew bigger and bigger.

An object of the present invention to solve the above problems is to reduce the harmful components discharged by the existing steel bracket for supporting the heat exchanger when washing/cleaning the spherical ceiling system air conditioner in a humid environment and condensate and rust on the surface of the bracket. to prevent this from happening.

In addition, the bracket made of stainless steel is manufactured by separating the female and male shapes, and it is composed of a removable sliding shape with a structure that can adjust the height in the up and down directions for easy coupling. The purpose is to improve user convenience.

Another object is to prevent in advance the risk of breaking as the steel bracket of the old system air conditioner is rusted and the vertical support is weakened, and the risk of fire that may occur when used as a heat exchanger for winter heating after being left in a rusted state for a long time.

In other words, when cleaning/cleaning the old ceiling type air conditioner, the surface material of the bracket is replaced with a stainless steel material, and when replacing, a sliding type heat exchanger support bracket that can be adjusted up and down is provided so that it can be easily replaced according to the shape and height of the installed heat exchanger. It is an object of the present invention to

The present invention for solving the problems of the prior art and achieving the above object is a ceiling heat exchanger support bracket for a ceiling air conditioner that has a ceiling portion and an inner wall and supports a heat exchanger installed along the inner periphery of a rectangular casing having an open front surface. The first bracket having a predetermined length for supporting the heat exchanger and a second bracket fixed to the ceiling of the casing and capable of being coupled and separated at a predetermined height while sliding with the first bracket, the first bracket comprises: A guide part bent along the side edge is formed, a U-shaped curved part surrounding the thickness of the bottom surface of the heat exchanger is provided at the lower part, and a plurality of fitting parts protruding by bending downward at 15 to 35° are formed on the upper rear surface, , The second bracket has a sliding part bent so as to be fitted into the guide part along the side edge thereof, and a plurality of fastening slit grooves are formed along the longitudinal direction so that the fitting part can be fitted on the front side, the upper side It is characterized in that the fastening guide part formed with a fastening hole for screwing with the ceiling part is formed by bending.

And, it is characterized in that the material of the support bracket is stainless steel.

When the stainless steel bracket structure according to the present invention having the above configuration is applied, a large amount of harmful components discharged while washing/cleaning the spherical ceiling system air conditioner is reduced while the existing steel bracket is immersed in a humid environment and condensed water, and the surface of the bracket is reduced. It has the effect of preventing rust phenomenon.

In addition, the bracket is manufactured by separating it into male and female shapes, and it has an effect of improving user convenience when washing/cleaning the air conditioner by configuring it in a shape that can be installed and detached in a structure that can be adjusted in the vertical direction for easy coupling.

In addition, it has another effect of preventing in advance the risk of breaking as the old system air conditioner iron bracket rusts and the risk of fire occurring when used as a heat exchanger during winter heating after being left in a rusted state for a long time.

Hereinafter, a preferred embodiment according to the present invention for solving the above problems will be described in detail with reference to the accompanying drawings.

Hereinafter, the illustration and description of the completed exterior of the ceiling-type air conditioner are the same as those described above with the known exterior, and since it is not related to the technical idea of the present invention, a detailed description will be omitted, and the motor of the central part installed inside the casing; The illustration of the blower fan and the drain pan and detailed description thereof will also be omitted.

When the shape of the heat exchanger support bracket according to the present invention is described with reference to FIG. 3, the technical idea of the present invention that the bracket of the shape mentioned in the prior art should be able to replace it when cleaning or washing the ceiling air conditioner In accordance with this, the size and shape of the bracket must be the same or similar. To this end, in the manufacturing process, sufficient investigation and self-verification were conducted on the shape and size of the support brackets in various existing products.

3 shows the ceiling 110 fixed to one side of the inside of the ceiling, the inner wall 120 extending in the downward direction integrally from the ceiling, and the casing 100 of an approximately square shape with the front part open and the lower part fixed to the ceiling. It is a perspective view seen from an upward direction.

First, in the present invention, stainless steel is used as the material of the support bracket 200. Accordingly, it can have the effect of suppressing surface corrosion and reducing the emission of a large amount of harmful components by replacing the existing iron bracket. there will be

In the casing 100, a blower providing blowing force is disposed on the central side, and the inside is hollow to mount the heat exchanger 300 between the inner walls of the casing 120 spaced apart by a predetermined distance around the blower. It is provided in the shape of a housing, and in this case, the blower includes a blowing fan for sucking air from the lower part and discharging it in a radial direction, and a driving motor for driving the blowing fan, and the driving motor is fixed to the center of the upper surface ceiling inside the casing 100 do.

For convenience, although the basic internal configuration of the casing 100 will be described, it should be considered that the internal configuration is already separated in the washing or cleaning process as shown.

The heat exchanger 300 is disposed on the radially outer side of the blower in a form surrounding the blower fan to exchange heat with air discharged from the blower fan, and the shape constituting the heat exchanger 300 is generally a coil and a tube. A fin tube type heat exchanger that is wound along a surface is mainly used, but includes, but is not limited to, all other commercially available fin type heat exchangers such as smooth corrugated, louver, and slit fin types currently used in ceiling air conditioners.

That is, the air that has passed through the blower fan inside the casing 100 is disposed at each edge of the casing 100 and passed through the heat exchanger 300 functioning as an evaporator or condenser to be cooled or heated, and then the cold air discharge flow path. As it passes through the air outlet and the air outlet, it is dispersed into the indoor space by the rotation of the blade so that the indoor space can be maintained at an appropriate temperature.

The drain pan is disposed at the lower part of the heat exchanger 300 to collect and discharge condensed water generated in the heat exchange process, and structurally supports the lower part of the heat exchanger 300 and is located on the outer surface of the heat exchanger 300 . It is common that a plurality of water storage grooves are provided on the upper surface so that the generated condensed water flows down and accumulates, and in the upper surface shape, a fitting portion of a corresponding shape is configured to accommodate the lower bottom surface of the heat exchanger 300 to secure the downward support force of the heat exchanger. The shape configuration is common.

The mounting position and fixing method of the heat exchanger 300 inside the casing 100 is a general fastening state in a number of ceiling heat exchangers 300 that are already known and marketed, and it is important in the present invention to install the heat exchanger It is the vertical height of the heat exchanger, which is a vertical plate type.

This replaces the steel bracket for supporting the existing ceiling-type air conditioner heat exchanger that covers and supports one side of the ceiling part 110 of the casing 100 and the thickness of the lower bottom of the heat exchanger 300. Exchange with a bracket made of stainless steel according to the present invention This is because fastening must be possible, and for this, a bracket 200 structure that can be extended in the height direction according to the height of the heat exchanger 300 mounted inside the previously installed well-known ceiling air conditioner casing 100 is required. A sliding bracket structure is applied.

Hereinafter, a preferred embodiment of the structure of the sliding bracket 200 according to the present invention will be described in detail with reference to FIGS. 3 to 6 .

The first thing to be considered is that the casing 100 is fixed at a certain depth inside the ceiling, and it forms an exterior and consists of a substantially rectangular box with an open front, and the inner wall 120 around the inside of the casing 100 ) and a vertical plate-shaped heat exchanger 300 having a certain height installed and installed on a slope at a predetermined distance apart from each other, and screw-coupled with the ceiling 110 inside the casing 100 on one side and bent on the other side As a result, the structure will be mainly described by limiting the bracket 200 for supporting the heat exchanger 300 in the vertical direction that surrounds and supports the lower bottom of the heat exchanger 300 .

That is, the heat exchanger support bracket structure in a state in which the drain pan is separated in the downward direction inside the general casing 100 that supports the heat exchanger 300 and has a drain pan for storing condensed water that is condensed to the surface of the cooling coil and flows. And it relates to the installation state, when the ceiling air conditioner is installed, one end of the support bracket 200 is screwed to support the heat exchanger 300 to the ceiling 110 inside the casing 100 in the vertical direction. The structure of the support bracket 200 in the case of using the bracket 200 as a member for supporting the base will be described in detail as follows.

first. The bracket 200 according to the present invention is divided into a first bracket 210 and a second bracket 220 to make a mold. As described above, a preferred material is stainless steel, which has strong adaptability when exposed to condensed water and a humid environment. It can be said that

Oxides are deposited on the surface like a film by oxidation of oxygen or moisture in the air. This is collectively called rust. Stainless steel covers the surface of the metal with an oxide film containing chromium and iron, which does not easily rust, and Since it has a unique property of preventing direct oxidation, it was selected as a replacement material in consideration of this property.

4 to 6, the support bracket 200 according to the present invention includes a first bracket 210 of a predetermined length for supporting the heat exchanger, is fixed to the ceiling of the casing, and slides with the first bracket. It is composed of a second bracket 220 that can be coupled and separated at a predetermined height as it is.

First, each shape in a state in which the first bracket 210 and the second bracket 220 are separated will be described. First, the first bracket 210 includes a guide part 211 bent along a side edge thereof. The lower portion is provided with a U-shaped curved portion 212 surrounding the thickness of the bottom surface of the heat exchanger 300, and a plurality of fitting portions 213 that are bent downward at 15 to 35° and protrude from the upper rear surface are provided. The curved portion 212 serves to support the lower portion of the inner surface of the heat exchanger 300 by wrapping a predetermined height from the bottom surface of the vertical plate-shaped heat exchanger 300 that surrounds the inside of the casing in a 360-degree direction. Although the vertical support of the heat exchanger is not shown, it goes without saying that the fixed support force is secured by the drain pan of FIG. 1 .

In this case, in general, an inner groove is formed to a thickness that can accommodate the shape of the bottom surface of the outer frame of the heat exchanger 300. In the case of a ceiling-type air conditioner heat exchanger, the installation height of the heat exchanger through which the refrigerant flows according to the room size is determined. Since most of the cases are adjusted and the thickness of the heat exchanger is fixed, the same thickness of the curved inner groove can be applied when the support bracket 200 is molded.

Then, in the upper center of the other side of the body of the first bracket 210, a plurality of fitting parts 213 protruding are formed by bending 15° to 35° downward in order to be fitted with the second bracket 220. do. This is a configuration for the user to freely adjust and fasten the height to the fastening slit groove 223 formed in a plurality of the second bracket 220 to be described later according to the installation height of the existing ceiling air conditioner heat exchanger 300 .

When the guide part 211 of the first bracket 210 is installed, it is bent upward at a predetermined height from the left and right ends of the first bracket 210 in the inner central direction of the casing 100, and the bent end is the first The bracket 210 is rounded in the inner direction of the body to form a shape so that the sliding part 221 of the second bracket 220 having a corresponding shape to be described later can easily move forward and backward along the guide part 211. desirable.

That is, the second bracket 220 is fully supported by the first bracket 210 and the sliding operation can be smoothly performed by upwardly bending molding and rounding the curved end to have a certain bending radius.

Next, the shape of the second bracket 220 will be described in detail with reference to FIG. 5 as follows.

As shown, the second bracket 220 is formed with a sliding part 221 bent to fit into the guide part 211 along the side edge thereof, and the fitting part can be fitted on the front surface. A plurality of fastening slit grooves 223 are formed along the longitudinal direction, and a fastening guide part 222 having a fastening hole 222a for screw coupling with the ceiling part is formed on the upper side is bent, and the fastening guide part 222 is formed. The upper frame of the heat exchanger 300 is able to secure vertical support force by screwing it in close contact with the fastening part of the ceiling 110 without a gap. At least one fastening hole 222a is provided, but it is preferable to form two or more in order to secure the vertical support force of the heat exchanger 300 during fastening. This close contact with the ceiling 110 is possible because the overall height of the support bracket 200 can be adjusted while the second bracket 220 goes through a sliding process.

And, in the center of the body of the second bracket 220, a plurality of straight fastening slit grooves 223 are formed in the center of the surface so that the fitting part 213 can be fixed at a desired position in the height direction during installation. In this way, as described above, by selecting a suitable location according to the height of the installed ceiling air conditioner internal heat exchanger 300, the user can arbitrarily install and fix the bracket 200.

In order to perform a function of moving the second bracket 220 forward and backward in the height direction for height adjustment, a sliding part 221 is formed on the second bracket 220. As shown, the sliding The part 221 is configured to have the same shape as the curved shape of the first bracket 210 guide part 211 , but the upward bending height is fine to be accommodated in the guide part 211 , but the first bracket guide part 211 . ), so that the sliding part 221 can easily move forward and backward in the height direction along the guide part 211 .

In order to manufacture such a height-adjustable sliding bracket 200, a hole formation is performed at a coverable position by repeating tests for bonding properties and dimensions according to various vertical heights of the heat exchanger 300 of a number of pre-installed manufacturers. After confirming that there is no problem, it is preferable to perform the bending operation by a molding machine.

6 shows a state in which the first bracket 210 fitting part 213 is fitted and fixed to the straight fastening slit groove 223 of the second bracket 220 at a height desired by the user, FIG. 6a is a fixed state for supporting the heat exchanger 300 of the smallest height and is a state in which the bracket 200 is coupled in a non-slid state, and FIG. 6B is a heat exchanger 300 having a relatively large support height of the heat exchanger 300. The bracket (200) is coupled by moving forward a certain length in the height direction to perform the role of the support bracket of the

As shown in FIG. 3 , the support bracket 200 for supporting the conventional heat exchanger according to the present invention, which is fitted and fastened in this way, is screw-coupled to one end of the second bracket 220 to the ceiling surface 110 inside the casing 100 . It is fixed, and one end of the first bracket 210 is supported and coupled in a shape that a bracket surrounds and supports the lower bottom frame of the heat exchanger 300, so that an integral bracket made of a fixed iron material and sliding according to the present invention, which was a problem in the past Since the expression support bracket is replaced and fastened to replace its function, it is possible to achieve the object of the present invention described above and to produce the effect.
