Description

Condensate Guide for Air Conditioners {device for guiding liquid comming into being from heat change of air conditioner}

The present invention relates to an air conditioner, and more particularly, to a condensate guide device of an air conditioner for guiding the condensate drained from the refrigerant pipe exposed to the outside of the heat exchanger to be collected into the condensate receiver without splashing to another place.

In general, an air conditioner refers to a cooling / heating system that cools a room by a repetitive action of sucking hot air in a room, exchanging heat with cold air, and then discharging it into the room, or heating the room by a reverse action.

In addition, it has various functions such as air purifying function that sucks polluted air in the room and filter it after making it into clean air, and dehumidification function that sucks in humid air and makes it dry and dry again.

Various types of air conditioners have been released to install them according to the installation conditions and the volume of the indoor space. In particular, the air conditioner of the type separated from the indoor / outdoor air which is most used these days is It is classified into a window type air conditioner that is installed in a window by combining indoor and outdoor air.

Such an air conditioner is a compressor (1) for forcing a refrigerant to a high temperature / high pressure superheated steam state regardless of its type, and the high temperature / high pressure steam refrigerant transferred from the compressor by convection with external air. A condenser 2 for liquefaction by heat exchange, an expansion valve 3 for isotropically expanding the liquid refrigerant transferred from the condenser, and converting it into a low / low pressure wet saturation steam, and from the expansion valve. It basically has an evaporator (4) for evaporating the refrigerant in the vapor state by heat exchange with indoor air, and cooling the room by a repetitive cycle in which the refrigerant is compressed → condensed → expanded → evaporated. Heating is achieved.

On the other hand, Figure 2 and Figure 3 is an exploded perspective view and assembled state longitudinal cross-sectional view of the wall-mounted indoor unit of the general detachable air conditioner, the configuration is the outer case 5 by the front / rear chassis (5a) (5b), A cold air outlet 5c is formed below the outer case 5 to discharge heat exchanged cold air, and an inlet grill having an air inlet 6a for sucking indoor air is formed on the front surface of the front chassis 5a. An inlet grille 6 is provided, and an air filter 7 is provided between the inlet grille 6 and the front chassis 5a for filtering foreign matter contained in the air to be sucked.

A heat exchanger (8) is provided on the air intake side of the outer case (5) for heat-exchanging indoor air with cold air. The rear side of the heat exchanger is fluidized in air while being rotated by the power of the fan motor (9). Is provided with a blower fan (or cross flow fan) 10 that allows air to be sucked and discharged through the air inlet 6a and the cold air outlet 5c, respectively.

In the air conditioner configured as described above, when the cooling mode is operated, external air (indoor air) is introduced into the outer case 5 through the air inlet 6a formed in the inlet grill 6 by the rotational force of the blower fan 10. The introduced hot air is heat-exchanged with the low temperature air while passing through the heat exchanger 8 installed inside the front chassis 5a, and is discharged into the room through the cold air discharge port 5c formed at the bottom of the outer case 5. As it gradually cools the room.

Meanwhile, first and second support plates 5c and 5d are formed on the left and right sides of the rear chassis 5b, respectively, and the shafts of the blower fan 10 are rotatably supported by both support plates. Heat exchangers 8 are provided at the ends of the two support plates.

In addition, electrical components such as a fan motor 9 and a control box 11 are installed between the second support plate 5d located on the right side and the edge of the rear chassis 5b when the rear chassis 5b is viewed from the front. The space part 12 for this is formed.

In addition, at the outlet side of the heat exchanger 8, a plurality of refrigerant pipes 8a extending from the heat exchanger are collected, and these refrigerant pipes are mostly integrated by tape, bent to the rear of the indoor unit, and then penetrate the interior wall surface. It is connected to the outdoor unit.

At this time, a horizontal piping groove 5e and a vertical piping groove 5f are inserted into the rear surface of the rear chassis 5b for inserting a plurality of strands of refrigerant pipes 8a extending from the heat exchanger 8 as shown in FIG. 4. Are formed to communicate with each other, these pipe grooves are formed for the purpose of preventing the indoor unit from being spaced apart from the installation wall as the refrigerant pipe (8a) is piped to the rear of the indoor unit.

Meanwhile, the outlet side refrigerant pipes 8a of the heat exchanger 8 are inserted into the vertical pipe grooves 5e and the horizontal pipe grooves 5f formed on the rear surface of the rear chassis in a state of being integrated with a tape or the like. In the process, the tape is wound only on the refrigerant pipe exposed to the outside of the rear chassis 5b.

Therefore, the refrigerant pipe 8a located inside the rear chassis 5b, particularly in the space 12, is not wound with the tape. At this time, the refrigerant flowing inside the refrigerant pipe 8a is in a low temperature state and thus relatively high temperature. Condensate is inevitably generated on the surface of the refrigerant pipe due to the temperature difference due to contact with the in-air air.

The condensed water generated on the surface of the refrigerant pipe 8a located in the space portion 12 drops as water is generated and increases as time passes. At this time, the condensate receiver 13 is disposed below the refrigerant pipe 8a. Since the installed condensed water from the refrigerant pipe is mostly collected, the collected condensate is discharged to the outside through the drain port 14 formed on one side of the condensate receiver (13).

In addition, the condensate guide passage 14 inclined downward toward the condensate receiver 13 as it passes through the front and rear of the space portion 12 between the second support plate 5d and the vertical pipe groove 5e, and goes from the rear to the front side. ) Is formed, and the condensate falling to the rear of the space 12 is guided to the front of the space 12 along the condensate guide flow path 14 to be introduced into the condensate receiver (13).

However, conventionally, since there was no separate guide device for guiding condensate between the refrigerant pipe 8a and the condensate receiver 13, all condensate generated in each portion of the refrigerant tube 8a is condensed into the condensate receiver 13. If not, some of them fall to other places and accumulate on the bottom surface of the space part 12. Thus, the accumulated condensate water leaks into the room and contaminates the room.

In addition, since the parts installed in the space part 12 are electric devices, if the condensate is not led to a predetermined path but scattered to another place, there should always be a risk of safety accidents such as a short circuit, even if a countermeasure is prepared.

The present invention has been made to solve the above-mentioned conventional problems, the object is to guide all the condensed water from the refrigerant pipe of the heat exchanger to the condensate receiving.

The present invention for achieving the above object is the first and second support plates formed on the inner left and right sides of the rear chassis for fixing the heat exchanger, the space portion formed between the second support plate and the rear chassis side end, and the rear Vertical and horizontal pipe grooves for inserting the refrigerant pipes extending from the heat exchanger to the rear of the chassis, a condensate guide flow path formed between the horizontal pipe grooves and the second support plate, and a refrigerant pipe of the heat exchanger in the lower portion of the space.

According to the present invention, the first and second support plates 5c and 5d and the second support plate 5d and the rear chassis 5b are formed at the inner left and right sides of the rear chassis 5b to fix the heat exchanger 8. Vertical and horizontal piping grooves 5e for inserting the space portion 12 formed between the side end of the rear surface and the refrigerant pipe 8a extending from the outlet side of the heat exchanger 8 to the rear surface of the rear chassis 5b. 5f, the condensed water guide passage 14 formed between the horizontal pipe groove 5f and the second support plate 5d, and a refrigerant pipe of the heat exchanger 8 at the lower portion of the space 12. An air conditioner having a condensate receiver (13) for receiving condensate produced in (8a);

A condensate guide member is provided between the refrigerant pipe 8a of the heat exchanger 8 located in the space 12 and the condensate receiver 13, so that the condensed water dripping from the refrigerant pipe 8a is condensed water guide member. It is to guide the whole amount to the condensate receiver (13) by.

In the condensate guide member as shown in Figure 5a integrally formed on the upper side of the outer surface of the second support plate (5d), the first guide plate 15 formed inclined downward from the rear toward the front, and the first guide plate A second guide plate 16 formed integrally with the second support plate 5d so as to be positioned below the 15 and inclined downward toward the condensate guide flow passage 14 from the upper end to the lower end, and the vertical pipe groove; It is formed in the lower part in 5e, and consists of the 3rd guide plate 17 (refer FIG. 5B, 5C) formed inclined downward toward the said condensate guide flow path 14 from the upper end to the lower end.

At this time, the first guide plate 15 is formed on the outer surface of the second support plate 5d so as to receive the condensed water falling from the coolant tube adjacent to the second support plate 5d in the coolant tube 8a.

Then, the second guide plate 16 is moved further to the right and forward from the first guide plate 15 so as to receive the condensed water falling from the refrigerant pipe 8a at a position outside the region of the first guide plate 15. To be located at the designated point.

Such positioning is for efficiently receiving the condensed water falling from the respective portions of the refrigerant pipe 8a by preventing the first and second guide plates 15 and 16 from overlapping each other.

Referring to the operation of the condensate guide device of the present invention configured as described above are as follows.

The condensate falling into the position adjacent to the second support plate 5d among the condensate generated in the refrigerant pipe 8a of the heat exchanger 8 located above the space portion 12 is integrally formed at the upper rear of the second support plate. Falling on the guide plate 15, the condensate that is dropped at this time naturally falls to the front of the first guide plate 15 because the first guide plate 15 is inclined downward toward the front.

In addition, the condensed water dropped from the first guide plate 15 is dropped into the second guide plate 16 or the condensate receiver 13 positioned at the lower portion thereof.

At this time, the condensed water dropped onto the second guide plate 16 naturally flows down into the condensate guide flow path because the second guide plate is inclined downward toward the condensate guide flow path 14, and the second guide plate 16 is Since it does not overlap with the first guide plate 15, the remaining condensate that cannot be received by the first guide plate among the condensate falling from the refrigerant pipe 8a is also guided to the condensate guide flow path 14.

On the other hand, the condensed water falling from the refrigerant pipe (8a) located in the upper portion of the vertical pipe groove (5e) falls to the third guide plate (17) located in the lower portion of the vertical pipe groove (5e), the third guide plate 17 is Since it is inclined downward toward the condensate guide flow passage 14, the condensed water dropped on the third guide plate 17 is guided to the condensate guide flow passage 14.

The condensate guided to the condensate guide channel 14 is inclined toward the condensate receiver 13 so that the condensate guide channel 14 finally collects the condensate receiver.

As described above, the present invention forms a guide plate between the refrigerant pipe and the condensate receiver, thereby solving the problem of condensate falling into the condensate receiver by receiving the condensate from the refrigerant pipe by the guide plate. It becomes possible.
