Description

Air Conditioner {Air-conditioner}

The present invention relates to an air conditioner, and more particularly, to prevent foreign matter from accumulating at an interval between a heating coil and a cooling coil, and in particular, contamination on the corresponding surfaces of the heating coil and the cooling coil facing each other is increased. The present invention relates to an air conditioner capable of preventing the heating coil and the cooling coil from functioning properly.

Air conditioners, also called air conditioners, thermo-hygrostats, and the like, control a constant space to a temperature, humidity, and airflow distribution suitable for human activity, and at the same time remove dust from the air.

Pleasant indoor temperature is subtle due to human sensation, but outside air and temperature difference is about 5 ~ 6 ℃ in summer, indoor temperature 25 ~ 29 ℃, humidity 60 ~ 70%, winter temperature 18 ~ 21 It is reported that about 55-70% of the humidity is good.

The principle of the air conditioner is to use the heat of evaporation that takes heat away from the liquid when the liquid evaporates, such as a refrigerator or a refrigerator. A liquid that is easy to evaporate even at a low temperature is used, and a freon gas is usually used.

The basic structure is a direct connection between the motor and the compressor in a sealed iron container, and the compressor is rotated by the motor to compress the refrigerant. Compressors are reciprocating and rotary. The condenser is equipped with aluminum fins on the surface of the copper pipe, and dissipates heat from the refrigerant into the air to cool the liquid. The capillary tube (capillary tube) is a device that lowers the pressure of the high pressure liquid refrigerant from the condenser and evaporates it in the next evaporator. It is a thin copper pipe having a diameter of about 1 mm. The structure of the evaporator is almost the same as the condenser, where the compressed refrigerant evaporates here and takes heat away from the surroundings. Therefore, the temperature of the air in contact with the surface of the evaporator is lowered, and the moisture in the air is removed as water droplets on the surface of the evaporator. The blower system is forcibly sending air for efficient heat exchange.

In the type of air conditioner, there is a central type of central unit, which is used for a large building, with a central unit and cooling / heating of each room by a duct there. There are also small unit types used in homes and offices, which are divided into two types according to the installation method.

The main body is integrated, and it is installed on the window and the wall, the window type for cooling the condenser by the outside air by taking the rear part of the cabinet outdoors, and the indoor unit with the evaporator and the blower in the indoor side, and the compressor and the blower in the outdoor side. There is a split type that uses an outdoor unit and connects the indoor unit to the outdoor unit using a refrigerant pipe. In addition, there are package types that use cooling water to dissipate heat by a condenser in the large ones installed on the floor, such as an office.

On the other hand, outdoor units are classified into various types according to their shape and structure. Normally, a casing is provided with a compressor, a condenser and a blower fan, which interact with the evaporator in the indoor unit to form one refrigeration cycle.

In contrast, the principle is similar, but the heating coil and the cooling coil in the casing, the air responsible for the condensation function through the refrigerant circulated along the heating coil and cooling coil Harmony exists. This method is mainly applied to large air conditioners.

However, in an air conditioner equipped with a heating coil and a cooling coil, the heating coil and the cooling coil are generally mounted in the casing so that the heating coil and the cooling coil are almost in contact with each other. There is a high possibility that foreign matter will accumulate between the heating coil and the cooling coil, because it is rarely present. There is a problem.

An object of the present invention is to prevent foreign matter from accumulating at the interval between the heating coil and the cooling coil, and in particular, the heating coil and the cooling coil function properly by increasing the contamination on the corresponding surfaces of the heating coil and the cooling coil facing each other. It is to provide an air conditioner that can prevent the phenomenon of not being in charge of.

The above object is provided with a plurality of internal components therein, the casing to form an exterior; A heating coil provided on one side of the casing to heat a refrigerant; A cooling coil provided to be spaced apart from the heating coil by a predetermined distance to cool a refrigerant; And a nozzle injection unit provided between the heating coil and the cooling coil to inject cleaning fluid toward the heating coil and the cooling coil.

Here, the nozzle injection unit, the supply pipe is disposed between the heating coil and the cooling coil, the cleaning fluid is supplied; And a plurality of injection nozzles coupled to the supply pipe along a length direction of the supply pipe to inject the cleaning fluid into at least one of the heating coil and the cooling coil.

The plurality of injection nozzles may be provided in a paired symmetrical manner to be inclined with respect to the axis of the supply pipe to simultaneously spray the cleaning fluid toward the heating coil and the cooling coil at the corresponding position.

Further comprising an outer frame for supporting the supply pipe, the supply pipe may be provided in two or more rows in the height direction on the outer frame, the cleaning fluid is circulated from the heating coil and the cooling coil (water May be).

According to the present invention, foreign matters can be prevented from accumulating at an interval between the heating coil and the cooling coil, and in particular, contamination is added to the corresponding surfaces of the heating coil and the cooling coil facing each other so that the heating coil and the cooling coil function properly. There is an effect that can be prevented from being in charge.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

The air conditioner according to the present embodiment controls the temperature, humidity, and air flow distribution suitable for human activity, and at the same time serves to remove dust and the like in the air.

Such an air conditioner, as shown in Figs. 1 to 6, has a unitary structure in which a plurality of internal parts (not shown) are mounted in a casing 10 forming an external appearance. That is, the shapes of FIGS. 1 to 3 are manufactured in a single unit, that is, in an assembly form, and are delivered or used.

Here, since the internal parts refer to parts described below, the internal parts are not given separate reference numerals.

As shown in Fig. 1, the casing 10 is a part forming an exterior of the present outdoor unit. It may be made of a metal material such as sus, and each surface may be formed of two layers of an inner plate and an outer plate with insulation therebetween. Thus, when the outer surface of the casing 10 is formed in two layers, there is an advantage that can further improve the condensation efficiency. However, since the scope of the present invention is not limited thereto, the casing 10 does not necessarily need to be manufactured in two layers.

This casing 10 is supported relative to the ground by the base 11. An air inlet 10a is formed at one side of the casing 10, and an air outlet 10b is formed at the other side of the casing 10.

A damper 12 is provided at one side of the casing 10, and a door 14 is provided around the damper 12 to allow entry and exit for maintenance of internal components in the casing 10. The door 14 may be any type of sliding type or sliding type.

A filter 16 is provided inside the casing 10 along a virtual air circulation line connecting the air inlet section 10a and the air outlet section 10b.

The filter 16 serves to filter foreign matter in the incoming air. In the present embodiment, two kinds of filters 16 are applied: pre-filter 16a and medium filter 16b. However, since the scope of the present invention is not limited thereto, two types of filters 16 need not necessarily be applied. It is also possible to add more types of filters not described.

The humidification part 18 is provided in the position spaced apart from the filter 16 along the air circulation direction. A discharge fan unit 20 for discharging air through the air discharge unit 10b is provided around the humidifying unit 18.

The discharge fan unit 20 has a blower 21 having an end communicating with the air discharge unit 10b and having a fan 21a therein, a drive motor 22 generating power, and a drive motor 22 of the discharge fan unit 20. A drive pulley 23 connected to the motor shaft, a driven pulley 24 coupled to the rotating shaft of the fan 21a, and a belt 25 for connecting the drive and driven pulleys 23 and 24 to each other.

Accordingly, when power is applied to the drive motor 22 and the drive motor 22 is turned on, the drive pulley 23 connected to the drive motor 22 rotates in one direction, and the rotational force thereof is the belt 25. And driven to the driven pulley 24, so that the fan 21a can rotate. Therefore, the air inside can be discharged to the air discharge unit 10b through the blower 21.

Between the filter 16 and the discharge fan unit 20, there are provided internal parts that substantially perform the condensation function.

That is, a heating coil 30 for heating the refrigerant, a cooling coil 40 for cooling the refrigerant, provided to be spaced apart from the heating coil 30, and the heating and cooling coils 30 and 40. The drain pan 50 provided in the lower part, the drain socket 51 connected to the drain pan 50, etc. are provided.

The heating and cooling coils 30 and 40 are coupled with pipes 31 and 41 to allow the refrigerant to enter and exit the heating and cooling coils 30 and 40, respectively. Here, the refrigerant is water, and the pipes 31 and 41 may form in and out of the refrigerant, and the pipes 31 and 41 of the heating and cooling coils 30 and 40 may be formed. May be connected to each other.

In this case, each of the two pipes 41 on the side of the cooling coil 40 may form in and out, and one pipe 31 on the side of the heating coil 30 may be a cooling nose. It can be connected to the in (41) pipe 41 on the side (40). However, the scope of the present invention is not necessarily limited thereto.

On the other hand, in the prior art, since the heating and cooling coils 30 and 40 were arranged in close proximity to each other, foreign matter was easily accumulated between the heating and cooling coils 30 and 40, and in particular, the cleaning was not easy. Contamination was aggravated on the corresponding surfaces of the heating and cooling coils 30 and 40 facing each other, so that the heating and cooling coils 30 and 40 did not function properly.

Therefore, in the present embodiment, a nozzle injection unit 60 for injecting a cleaning fluid toward the heating and cooling coils 30 and 40 is provided between the heating and cooling coils 30 and 40 to solve the conventional problem. .

Here, the cleaning fluid may be water, which is a refrigerant of the heating and cooling coils 30 and 40, and may be independently provided along a separate line and supplied to the nozzle injection unit 60, or heating and The water circulated from the cooling coils 30 and 40 may be used. The latter case may be more advantageous to reduce costs and simplify equipment.

However, the cleaning fluid may also be air in addition to water. That is, it is possible to clean the corresponding parts of the heating and cooling coils 30 and 40 by being connected to a separate compressor and spraying air by the operation of the compressor.

4 to 6, the nozzle injection unit 60 of the present embodiment includes an outer frame 61, a supply pipe 62, and a plurality of injection nozzles 63.

The outer frame 61 is formed of a metal material as a part forming a frame of the nozzle injection unit 60, and is fixedly installed in the space between the heating and cooling coils 30 and 40. The fixing method is mainly a bolting method, but a bonding method may be applied in some cases.

The supply pipe 62 is a pipe to which water, which is a cleaning fluid, is supplied and is disposed between the heating and cooling coils 30 and 40 in a state of being coupled to the outer frame 61.

Since the outdoor unit of the present embodiment has a large capacity, the supply pipe 62 is provided in two rows along the height direction on the outer frame 61. However, since the scope of the present invention is not limited thereto, the supply pipe 62 may be provided in one row or three or more rows for higher efficiency.

The plurality of injection nozzles 63 are coupled to the supply pipe 62 along the longitudinal direction of the supply pipe 62 and sprayed water toward the heating and cooling coils 30 and 40 at the corresponding positions, thereby heating and cooling. It serves to clean the coil (30, 40).

In the case of this embodiment, the plurality of injection nozzles 63 are arranged at equal intervals in the supply pipe 62, but need not necessarily have equal intervals. However, it can be expected that the greater the number of injection nozzles 63, the higher the cleaning efficiency will be.

On the other hand, since the role of the spray nozzles 63 is to spray the water toward the heating and cooling coils (30, 40) to clean the heating and cooling coils (30, 40), the injection nozzles 63 are supplied to the supply pipe 62 ), The nozzle end of the injection nozzles 63 should be able to face the heating and cooling coils 30 and 40, and this installation structure is sufficient.

However, in the present embodiment, in consideration of the convenience of installation and the improvement of the efficiency, the supply pipe so that the plurality of injection nozzles 63 can simultaneously spray water toward the heating and cooling coils 30 and 40 at the corresponding positions. The pair of pairs of symmetrical inclinations with respect to the axis of 62 are provided.

That is, as shown in an enlarged view in FIG. 4, each of the plurality of injection nozzles 63 is coupled to the supply pipe 62, and the water flowing into the supply pipe 62 is inclined to be symmetrically arranged in pairs. Since it can be branched from each other to the heating and cooling coils 30 and 40 through a pair of injection nozzles 63, respectively, there is an advantage that the cleaning efficiency of the heating and cooling coils 30 and 40 can be further improved.

In addition, since the inclination direction of the injection nozzles 63 is provided to be inclined downward, foreign matters or contamination on the heating and cooling coils 30 and 40 are washed down while being washed down by the water pressure from the injection nozzles 63. Since it can be the advantage that can increase the efficiency more.

As such, according to the present exemplary embodiment, foreign matters may be prevented from accumulating at intervals between the heating and cooling coils 30 and 40, and in particular, the surfaces of the heating and cooling coils 30 and 40 facing each other may be contaminated. This weighting can prevent the phenomenon that the heating and cooling coils 30 and 40 do not function properly.

As described above, the present invention is not limited to the described embodiments, and various modifications and changes can be made without departing from the spirit and scope of the present invention, which will be apparent to those skilled in the art. Therefore, such modifications or variations will have to be belong to the claims of the present invention.
