Description

Draining structure for window type air conditioner

The present invention relates to a drainage structure of an integrated air conditioner, and more particularly, so that water generated when melting of the pipe part of the integrated air conditioner is melted can be drained to a predetermined drain passage via the inside of the air conditioner. It relates to a drainage structure of the integrated air conditioner is configured.

The integrated air conditioner refers to an air conditioner installed directly on a window because the indoor unit and the outdoor unit are integrated, and FIG. 1 illustrates a basic configuration of the integrated air conditioner except for the outer casing. As shown, the evaporator 2 which is an indoor side heat exchanger for producing the cold air supplied to the room is provided in the indoor side of the integrated air conditioner. And behind the evaporator 2, an air guide 4 for guiding the flow of air via the evaporator 2 is provided. The air guide 4 sucks air from the front of the evaporator 2 to make cold air in a relatively low temperature state via the evaporator 2, and then forms a cold air extraction unit 4b formed at one side of the evaporator 2. This part guides the flow of air so that air can be introduced into the room through).

And a compressor 8 for compressing the refrigerant is provided on one side of the rear of the air guide (4). In order to condense the refrigerant compressed by the compressor 8 on the outdoor side, a condenser, which is an outdoor side heat exchanger, is installed. The condenser is surrounded by the shroud (6) except for the back side.

In such an integrated air conditioner, a barrier 9 (see FIG. 2) is installed on the rear surface of the air guide 4 to prevent noise generated by a compressor or the like from entering the room. A part of the indoor side may be regarded as an indoor unit, and the rear side may correspond to an outdoor unit.

FIG. 2 is an exploded perspective view illustrating an exploded view of the interior part of the integrated air conditioner. As shown, the evaporator 2 is installed at the most indoor side, and the air guide 4 is installed at the rear surface of the evaporator 2. The air guide 4 is provided with an inlet portion 4a for introducing indoor air through the evaporator 2 and a cold air extraction portion 4b for supplying the cooled air back to the interior. The bottom of the air guide 4 is formed of a condensate receiver 4c. The condensate receiver 4c has a function of receiving water generated inside during operation of the air conditioner and draining it to the outdoor side. Therefore, the condensate receiver 4c is inclined to the outdoor side so that water can be drained to the outdoor side.

The scroll portion 7 is fastened to the air guide 4 on the rear surface of the air guide 4. A blower (not shown) is formed inside the scroll portion 7 to form a flow of air, and substantially introduces indoor air through the evaporator 2 and supplies it to the cold air blowout portion 4b. It forms a flow of air to supply cold air to the room.

The barrier 9 as described above is provided on the rear surface of the scroll unit 7. Of course, the barrier 9 has a function to prevent noise generated by the integrated air conditioner from being transmitted to the indoor side and to reinforce the strength of the product.

3 shows a combined state of the indoor unit as described above. When such an air conditioner is operated, condensation occurs in the evaporator 2 due to such a temperature difference because the evaporator 2, which is a heat exchanger of the indoor unit side through which the refrigerant passes, is in a low temperature state, and the air introduced from the room is in a high temperature state. Water droplets form. When the water droplets formed on the evaporator 2 grow in this way, the water drops to the condensate receiver 4c of the air guide 4, and the water accumulated on the condensate receiver 4c is drained to the outdoor side along its own slope.

However, when the temperature difference of the surrounding environment where the air conditioner is used is severe, for example, when the temperature suddenly drops a lot at dawn, freezing occurs around the pipe 12 connected to the evaporator 2 which is an indoor heat exchanger. . When freezing occurs around the pipe 12 in this way, a lot of troubles occur in the circulation of the refrigerant, and thus, the operation of the compressor 8 is excessively generated, and the phenomenon in which the compressor 8 is substantially overheated occurs. .

When the compressor 8 is overheated, the operation of the compressor is stopped by a sensor (for example, an overload protector) that detects the compressor 8. When the compressor is stopped and a predetermined time elapses, the ice around the pipe 12 is also thawed and melted.

However, water generated due to melting of ice around the pipe 12 substantially flows down the side of the scroll portion 7, and thus may not flow into the condensate receiver 4c of the air guide 4. If the molten water cannot flow down into the condensate tray 4c, it actually flows down the wall or window where the air conditioner is installed, which causes various disadvantages in relation to the surrounding facilities.

For example, the melted water must be collected in the condensate receiver 4c and drained to the outside along a predetermined drainage path. However, when water flows along a window or a wall instead of a predetermined drainage path, an electrical leak such as a short circuit may occur. There are safety and appearance problems, such as a risk may occur.

The present invention is to solve the above problems, by draining the water generated in the integrated air conditioner along the predetermined drainage path through the air guide, to solve the electrical hazards and aesthetic problems caused by the drainage It is done.

According to another embodiment of the present invention, one side of the air guide in close contact with the downward drain groove, is provided with a guide rib protruding inward along the downward drain groove. The guide ribs serve to prevent water flowing along the down drainage groove from spreading outward.

According to another embodiment of the present invention, the upstream portion of the drain guide portion which is formed to be inclined is formed wider than the downstream portion. By forming in this way, even if a small amount of water falls into the downward drainage groove, it is possible to smoothly guide the downward drainage groove.

And according to another embodiment of the present invention, the side of the scroll portion, the lower end is formed with a side drain groove connected to the condensate and the inclined guide surface for guiding water from the top of the side drain groove to the side drain groove It is. According to such a configuration, even if the amount of water falling from the pipe is large and overflows to the side surface of the drain guide portion, it is possible to safely guide such water to the condensate receiver.

Next, the present invention will be described in more detail with reference to the embodiments of the present invention shown in the drawings.

Figure 4 is an exploded perspective view showing an exploded interior portion of the integrated air conditioner according to the present invention. As shown, the evaporator 22 which is an indoor side heat exchanger is provided in the indoor side part of the integrated air conditioner by this invention. The air guide 24 and the scroll unit 10 are provided on the rear surface of the evaporator 22. A barrier 26 is installed at the rear of the scroll unit 10 to prevent the noise of the compressor generated from the outdoor unit from being introduced into the room.

The air guide 24 is provided with an inlet part 24a through which air in the room flows and a blowout part 24b which sends air back to the room. And the bottom surface of the air guide 24 is molded into a condensate receiver (24c). The structure of the condensate receiver 24c is formed by extending to the bottom side of the air guide 24 as well as the front side bottom of the air guide 24. Accordingly, the condensate receiver 24c of the air guide 24 may collect water flowing along the side surface 14 of the scroll unit 10 as well as water generated and flowing down from the evaporator 22. It is formed to be.

In addition, a scroll unit 10 is installed on the rear surface of the air guide 24. A blower (not shown) is built into the scroll unit 10 to suck air in the room via the evaporator 22 by the rotation thereof, and then to take out the air 24 of the air guide 24. It can be discharged to the room through.

In addition, a pipe 30 (see FIG. 6) for allowing the refrigerant to enter and exit the inside of the evaporator 22 may be installed to pass through the upper outer side of the scroll unit 10.

According to the present invention, the side surface 14 of the scroll portion 10 is formed with a drain guide portion 13 for guiding water flowing down from the pipe 30 (see FIG. 6). The drain guide portion 13 is formed on the upper surface of the side surface 14 of the scroll portion 10, and is formed to be inclined downward toward the indoor side surface. Therefore, the water falling into the drain guide portion 13 is guided along the inclined surface of the room, and then falls downward along the downward drainage groove 13c. Here, water guided downward along the downward drainage groove 13c substantially falls into the condensate receiver 24c of the air guide 24.

The width in the transverse direction of the upstream portion 13a of the drain guide portion 13 is formed to be wider than the width in the transverse direction of the downstream portion 13b. Forming a wide area of the upstream portion 13a of the drain guide portion 13 and narrowly forming an area of the downstream portion 13b in this way so that even a small amount of water can easily flow along the drain guide portion 13. It is to.

In addition, the downward drainage groove 13c formed downward along the downstream portion 13b of the drain guide portion 13 is formed on the front surface 11 of the scroll portion 10 substantially. The front surface 11 of the scroll unit 10 is in close contact with the rear surface of the air guide 24 when the scroll unit 10 is assembled in a state of being in close contact with the air guide 24. Therefore, the molded part of the downward drain groove 13c formed on the front surface 11 of the scroll unit 10 will be assembled in a state of being in close contact with the contact surface 24e on the rear surface of the air guide 24.

When the front surface 11 in which the downward drainage groove 13c is formed is in close contact with the rear surface of the air guide 24, the downward drainage groove 13c and the close contact surface 24e of the air guide 24 are combined to form one drain passage. Will be configured. It can be seen that this configuration is clearly shown in the partial enlarged view in FIG. 6, and in FIG. 6 such drainage passage is shown at 32.

And as mentioned in the prior art, on the back of the scroll unit 10, the barrier 26 is installed to suppress the noise generated by the compressor of the outdoor unit, etc. to be transmitted to the indoor side as much as possible.

5 shows a scroll unit 10 according to another embodiment of the present invention. The scroll portion 10 according to the present embodiment has a side drainage groove 14a on the side surface 14 in addition to the configuration of the drainage guide portion 13 and the downward drainage groove 13c formed on the front surface 11 as described above. It is configured to further include the configuration.

That is, the side drain groove 14a is molded in the side surface of the scroll part 10 of this embodiment. An inclined guide surface 14b inclined downward toward the center is formed at an upper portion of the side drain groove 14a, so that water flowing along the side surface 14 of the scroll portion 10 is moved to the side drain groove 14a. You will be guided.

In the present embodiment, even when water falling into the drain guide portion 13 flows down the side surface 14 of the drain guide portion 13 beyond the side jaw 12a, the water is supplied to the air guide 24. It is configured to be guided to the condensate receiver (24c).

Next, the function of the drainage structure according to the present invention will be described with reference to FIG. 6.

As described above, the pipe 30 for allowing the refrigerant to enter and exit the evaporator 22 may freeze depending on the operating environment of the air conditioner. In this case, the pipe 30 may be stopped by stopping the driving of the compressor. And melting of ice around it.

An exemplary diagram in which the water generated in this way flows is shown in FIG. 6. In fact, it can be seen that the pipe 30 connected to the evaporator 22 is designed to pass through the upper side of the scroll unit 10 and the air guide 24 described above.

When the freezing of the pipe 30 melts and flows down, the pipe 30 falls to the drain guide portion 13 of the scroll portion 10 corresponding to the lower portion thereof. Here, the water flowing down the pipe 30 in the portion adjacent to the evaporator 22 actually falls through the evaporator 22 or directly to the condensate receiver 24c of the air guide 24.

Then, the water dropped to the drain guide portion 13 flows down the room side along the inclined surface, and then falls downward along the downward drainage groove 13c. In this case, since the downward drain groove 13c is in close contact with the contact surface 24e of the air guide 24, the drain passage 13c is actually disposed between the downward drain groove 13c and the contact surface 24e. 32) is formed as described above. In the drain passage 32, a guide rib 24d protruded downward along the downward drainage groove 13c is formed in the contact surface 24e of the air guide 24. As shown in FIG. The guide ribs 24d are configured to allow the water flowing downward to flow smoothly along the drain passage 32 formed by the downward drain groove 13c.

In this way, the water flowing downward along the downward drainage groove 13c flows down to the lowest end of the scroll portion 10 and then falls to the condensate receiver 24c of the air guide 24. The water thus dropped to the condensate 24c will be drained to the outdoor side along a path naturally defined by its inclination.

If the amount of water that melts and flows down from the freezing of the pipe 30 or the position of the pipe 30 is shifted outwardly, the water flowing out of the pipe 30 is the side surface of the scroll part 10. Overflow to (14) may occur.

When the water flowing in this way flows down along the side surface 14 of the scroll portion 10, the water is collected at the center by a pair of inclined guide surfaces 14b formed on the side surface 14, and then the side drainage grooves. Will fall down along (14a).

The water falling downward along the side drain groove 14a also falls into the condensate receiver 24c of the air guide 24. Therefore, by the inclination of the condensate receiver 24c itself is drained along the drainage path determined to the outdoor side.

According to the present invention as described above, forming the downward drainage groove 13c for guiding the water flowing down the pipe 30 to the condensate receiver 24c of the air guide 24 to the scroll portion 10. I assume it is a basic technical idea. Within the scope of the basic technical idea of the present invention, of course, many other modifications are possible to those skilled in the art. For example, the shape of the downward drainage groove, its forming position, and the like may be differently modified with respect to the position and shape within the technical range in which the water guided thereto may be guided to the lower condensate receiver 24c.

According to the present invention as described above it can be expected the following advantages.

According to the present invention, while the air conditioner performs normal operation, water droplets formed on the evaporator which is the indoor unit side heat exchanger are collected by the condensate receiver of the air guide and then drained to the outdoor part of the integrated air conditioner along a predetermined path. In addition, when the air conditioner performs cooling operation when the indoor temperature is, for example, 21 ° C. or lower, freezing around a pipe connected to the indoor heat exchanger is generated, and water generated by greening is also produced by the present invention. It is collected in the condensate receiver of the air guide along the downward drain groove or the side drain groove. Therefore, the generated water can also be drained to the outdoor side along the normal drainage passage via the inside of the air conditioner. By such a configuration, it is possible to solve the electrical problem which may be caused by the water generated inside the air conditioner flowing down the wall or window in which the air conditioner is installed, and thus, in terms of safety and appearance, You can expect the advantage of being able to solve the problem sufficiently.
