Description

  The present invention relates to a structure for improving air conditioning performance in an indoor unit of an air conditioner mainly including a heat exchanger and electric parts.

  In recent years, air conditioners have been required to save power, and there is a method of expanding the heat exchanger of an indoor unit as one method for saving power. If the heat exchanger is expanded, the heat transfer area is increased and the amount of heat exchange is increased. As a result, the air conditioning performance is improved and the same air conditioning effect can be produced with power saving. That is, it is possible to save power by simply enlarging the heat exchanger built in the indoor unit and increasing the outside dimension of the indoor unit. Therefore, in order to meet the demand for power saving for air conditioners, in recent years, heat exchangers have been expanded, and the external dimensions of indoor units have tended to increase accordingly.

  However, it is desirable that the indoor unit be smaller than the current size because of indoor installation and installation, and it is difficult to simply increase the size of the indoor unit in order to save power by expanding the heat exchanger. Moreover, the heat exchanger provided in the indoor unit of a recent air conditioner has an upper front heat exchanger part and an upper rear heat exchanger part above the cross-flow fan so that the longitudinal cross-sectional shape becomes an inverted V shape. The lower heat exchanger part is arrange | positioned in front of the cross-flow fan in the lower part of the upper front heat exchanger part. As described above, since the heat exchanger has been arranged not only in the vertical direction but also in the depth direction of the indoor unit, the indoor unit has a shape that greatly protrudes from the wall when installed in the room. Although the heat transfer area of the indoor heat exchanger arranged in the indoor unit has been expanded by such means, the size of the indoor unit of the wall-mounted room air conditioner is limited, and the indoor unit is further increased in size. I can't.

  However, on the other hand, there is a strong demand for improving performance for power saving, and for this purpose, it is necessary to further expand the heat transfer area of the indoor heat exchanger. In recent years, as described in Patent Document 2, a ventilation unit that exhausts indoor air to the outside may be attached to the air conditioner. In this case, the ventilation unit is disposed beside the indoor heat exchanger. Inevitably, the heat transfer area of the indoor heat exchanger is further reduced and there is a problem that the performance deteriorates.

  Therefore, air conditioning performance is improved by expanding the heat exchanger while maintaining the outer dimensions of the indoor unit, and air conditioning performance is maintained by maintaining the dimensions of the heat exchanger even if the outer dimensions of the indoor unit are reduced. An example is described in Patent Document 1.

  This is because the electrical component unit (electrical product storage box) built in the indoor unit of the air conditioner is elongated and placed in the longitudinal direction of the indoor unit, specifically, the front heat placed at the lower front of the indoor unit. It is arranged in front of the dew receiving tray that receives dew from the exchanger, and the heat transfer area is expanded by expanding the heat exchanger to the space next to the heat exchanger where the electric component unit has been conventionally arranged. .

  However, the technique described in Patent Document 1 has a problem that the performance of the heat exchanger is locally degraded. That is, the electric component unit is disposed in front of the front surface of the dew tray provided at the lower part of the front heat exchanger. The heat exchanger and the electrical component unit are brought close to each other, and the inflow state of air into the heat exchanger is deteriorated, and a region having a relatively low heat exchange performance is locally generated.

  In an indoor unit of an air conditioner, when an electrical component unit is installed on the upstream side of the heat exchanger that is the front surface of the indoor unit, air conditioning performance is further improved by improving the air inflow state to the heat exchanger be able to.

  Hereinafter, an embodiment of the present invention of an air conditioner will be described. In the present embodiment, a heat exchanger that performs heat exchange and an electrical component involved in air conditioning operation control are applied to a separate and wall-mounted air conditioner that is provided in an indoor unit.

  The indoor unit of the air conditioner according to the present embodiment is shown in FIGS. 1 and 2, FIG. 1 shows a schematic structure of the whole indoor unit of an air conditioner, and shows the indoor unit from the front. FIG. 2 shows a schematic structure from the side of the indoor unit, and shows a side cross section of the indoor unit.

  A front panel 1 is located on the front side of the indoor unit, and a top grill 2 is installed on the top side. The upper part of the front panel 1 is attached to the unit frame 3, and the front panel 1 can be opened and closed from the lower part with the upper part as a fulcrum. Further, the front panel 1 can be detached by removing the upper part from the unit frame 3. The top grill 2 is also attached to the unit frame 3 and is detachable. A transverse wind direction plate 11 is installed on the lower surface side of the indoor unit, and this transverse wind direction plate 11 is attached to the casing 9. The air outlet of the indoor unit can be opened and closed by rotating the side wind direction plate 11. As an overview of the indoor unit, the outer shape is substantially constituted by the front panel 1, the upper surface grill 2, the unit frame 3, the cross wind direction plate 11, the casing 9, and the like.

  A pre-filter 4 is located immediately inside the front panel 1 and the top grill 2 of the indoor unit. The prefilter 4 is attached to the unit frame 3 and can be detached from the unit frame 3 by sliding. An air purification filter 5 is installed inside the pre-filter 4 and is located on the front side of the indoor unit. The air purification filter 5 is also attached to the unit frame 3 so that it can be detached.

  A heat exchanger 7 is installed further inside the indoor unit, and is arranged so as to surround the cross-flow fan 8. The heat exchanger 7 is bent at a total of three places, one on the indoor unit upper side and two on the front side. That is, the heat exchanger 7 includes an upper rear heat exchanging portion 7a, an upper front heat exchanging portion 7b, a front heat exchanging portion 7c, and a front lower heat exchanging portion 7d. The upper rear heat exchanging portion 7a and the upper front heat exchanging portion 7b are arranged in a substantially inverted V shape as shown in FIG. Further, a front heat exchange section 7c is arranged substantially upright below the upper front heat exchange section 7b, and a lower front heat exchange section 7d, which is the lowermost heat exchange section, is arranged at about 30 ° from the vertical. The lower side is inclined to the cross-flow fan 8 side. And it is mounted on the two ribs erected on the bottom surface of the dew tray 9b below the front lower heat exchanger 7d. Between these heat exchange sections, a flat heat exchanger may be cut and bent, or may be an independent heat exchanger.

  Cross-flow fan 8 is arranged so as to be sandwiched between casings 9. In other words, a nose associated with the function of the dew receiving tray 9b is sandwiched between the front casing of the cross-flow fan 8 and a rear casing 9a that forms a ventilation path. In addition, the bottom back surface of the dew receiving tray 9b is a ventilation path.

  The end of the rotating shaft of the once-through fan 8 is connected to a motor. The vertical wind direction plate 10 is attached to the casing 9, and rotates with the attachment portion as a fulcrum.

  The refrigerant copper pipe 16 which is a refrigerant pipe constituting the refrigeration cycle by connecting the indoor unit and the outdoor unit is covered with a heat insulating material, and is piped on the back side of the indoor unit near the casing 9.

  The electrical component unit 12 is formed in an elongated shape, and the electrical component unit 12 includes a microcomputer substrate that controls the air conditioner, a substrate that communicates with the outdoor unit, a substrate that generates a signal for driving the cross-flow fan 8, and the like. It is formed and stored in a size that fits the width of the. Even if all the circuit boards are accommodated in one electrical component box to constitute the electrical component unit 12, the electrical component unit 12 may be constructed by accommodating the circuit boards in each of the plurality of electrical component boxes. Any of the embodiments may be used. The electrical component unit 12 is installed in the front portion of the indoor unit and is disposed on the lower front surface of the heat exchanger 7. That is, the electrical component unit 12 is arranged on the front surface of the front wall of the dew receiving tray 9b so that the longitudinal direction is the width direction of the indoor unit. In the gap between the heat exchanger 7 and the electrical component unit 12, a partition member 6a that forms the front wall of the dew tray 9b and partitions the front wall is interposed. The wall surface of the partition member 6a facing the heat exchanger 7 is maintained at an appropriate distance without being in contact with the heat exchanger 7 for the reason described later, and is a substantially flat wall surface. An electrical component 13 is installed on the front surface of the electrical component unit 12, and the electrical component 13 is positioned inside the display unit 15 when covered by the front panel 1.

  Although not shown, the indoor unit in the present embodiment includes a ventilation unit. In FIG. 1, an electric motor for driving the cross-flow fan 8 is arranged beside the right heat exchanger 7 as viewed in the drawing, and this ventilation unit is arranged beside the left heat exchanger 7. Explain the function of the ventilation unit. The exhaust function is a function of discharging the air sucked from the indoor suction port opened in the front panel 1 on the front surface of the ventilation unit to the outside through a duct from the air supply / exhaust port provided on the rear surface of the ventilation unit. In the air supply function, outdoor air sucked from the air supply / exhaust port is blown out to the air supply duct 14 provided in the indoor unit via the air purification filter, and is carried to the front of the indoor unit. In this case, the air blower is blown out from a ventilation blower opening between the air blower blown out of the once-through fan 8 and the electrical component unit 12. The air circulation function is a function of blowing out indoor air sucked from the indoor suction port to the air supply / ventilation duct 14 and blowing it out from the ventilation outlet.

  As shown in FIG. 2, the air supply duct 14 is arranged at the lower part of the electrical component unit 12, and when the front panel 1 is covered with the indoor unit, the air supply duct 14 (the air supply duct 14 (this In the cross section, the ventilation outlet) is visible.

  The function and operation of the indoor unit of the air conditioner configured as described above will be described mainly assuming a state in which cooling and heating operations are performed.

  The air conditioner starts operation by receiving an operation signal from the remote controller in the electrical component 13 of the electrical component unit 12 located in the back of the display unit 15 of the front panel 1. The lightning color of the electrical unit 13 changes according to the operation mode, and the operation mode can be determined by checking the color from the display unit 15 of the front panel 1.

  The side wind direction plate 11 is rotated by the control from the electric component unit 12 and opens the outlet of the indoor unit that has been covered. Further, by operating the remote controller, the horizontal wind direction plate 11 and the vertical wind direction plate 10 are controlled via the electric component unit 12, and the wind direction of the indoor unit can be changed. When the indoor unit receives the operation signal, the outdoor unit also operates.

  The refrigerant sent from the outdoor unit circulates through the heat exchanger 7 via the refrigerant copper pipe 16. The motor connected to the cross-flow fan 8 is rotated according to the operating state under the control of the electric component unit 12. When the once-through fan 8 starts to rotate, air is mainly sucked from the top grill 2 and passes through the prefilter 4 and flows into the indoor unit. When passing through the prefilter 4, the dust is removed from the air. The air purification filter 5 installed further inside the pre-filter 4 cleans the air. Through the above-described process, the air flows into the heat exchanger 7 and is exchanged. In the lower part of the heat exchanger 7, the air smoothly flows between the partition member 6 a and the heat exchanger 7 and flows firmly to the lowest end of the heat exchanger 7. The heat-exchanged air is sucked into the once-through fan 8 and flows out toward the casing 9 so as to penetrate the once-through fan 8. The air direction is controlled by a horizontal wind direction plate 11 and a vertical wind direction plate 10 provided on the downstream side of the casing 9 and blows out from the outlet of the indoor unit. In addition, an air supply / exhaust function is added, and air supply from the outside to the room, air discharge from the room to the outside, and air circulation in the room can be selected. When these air supply / exhaust functions are used, airflow is blown out from the air supply duct 14 installed at the lower part of the front panel 1. The airflow from the air supply duct 14 also serves to control the airflow of the air blown out from the casing 9.

  The operation and effect of the present embodiment having the above configuration will be described. In the indoor unit according to FIG. 4 of Patent Document 1, the front lower heat exchanging portion 7d is approximately 30 with respect to the installation wall surface (the wall surface is usually perpendicular to the floor surface) as in the embodiment shown in FIG. ° It is installed at an angle so that the lower part is in the direction of the once-through fan 8. And the partition member 6a is arrange | positioned at the front surface similarly to a present Example, and the electrical component unit 12 is arrange | positioned in the front. And as for the partition member 6a in this patent document 1, the lower part is in contact with the front surface of the front lower heat exchange part 7d, and the upper part is inclined about 20 degrees in the direction away from this front lower heat exchange part 7d. That is, the partition member 6a is inclined by approximately 50 ° with respect to the wall surface to be installed.

  In this state, if the dew receiving tray 9b performs the cooling operation or the dehumidifying operation that performs the function, the dew that has been transmitted to the front lower heat exchange section 7d and generated in the front lower heat exchange section 7d As a result, a phenomenon occurs in which the partition member 6a and the front lower heat exchange portion 7d are bridged by surface tension. If this bridging phenomenon occurs, dew will accumulate on the phenomenon, and air will not flow to the lower part of the front lower heat exchange part 7d due to this dew, resulting in a deterioration in heat exchange performance.

  In Patent Document 1, only the electric component unit 12 is disposed in front of the partition member 6a. However, in the present embodiment, a ventilation duct 14 is disposed below the electric component unit 12. As described above, the partition member 6a in Patent Document 1 is inclined by approximately 50 ° with respect to a plane perpendicular to the floor surface. For this reason, if it is going to arrange | position the ventilation ventilation duct 14 under the electrical component unit 12, since the ventilation ventilation duct 14 is taken as the magnitude | size which a cross-sectional area does not become a wind path resistance, the electrical component unit 12 is an angle of about 50 degrees. It will extend forward and upward. For this reason, since the electrical component unit 12 penetrates the front panel 1, the unit frame 3 must be expanded and accommodated as a whole. Therefore, there exists a problem that the depth dimension of an indoor unit becomes large. In addition, when not only the air supply / ventilation duct 14 but the height dimension of the electrical component unit 12 is increased, the same problem occurs when other components are arranged.

  In order to improve the air conditioning performance and to reduce the outer dimensions of the indoor unit, the electrical component unit 12 is arranged on the lower front side of the heat exchanger 7 (between the dew pan 9b and the front panel 1). This is the same as Document 1. As a result, it is not necessary to arrange the electrical component unit 12 on either of the left and right ends of the indoor unit, and it is possible to improve the air conditioning performance by expanding the heat exchanger 7 to the vacant space. Alternatively, it is possible to reduce the outer dimensions of the indoor unit while maintaining the air conditioning performance by omitting the vacant space.

  However, since the electrical component unit 12 and the heat exchanger 7 are close to each other, when they are simply arranged, an inflow state of air locally deteriorates and a region having a relatively low heat exchange performance occurs. Further, during the cooling operation, a lot of dew is generated in the heat exchanger 7 due to dew condensation, and the partition member 6a and the heat exchanger 7 adhere to an adjacent region. When dew adheres, the air inflow path is blocked, the inflow of air to the heat exchanger 7 on the downstream side of the adhered region is drastically reduced, and the heat exchange performance is greatly deteriorated locally. For this reason, a structure in consideration of the inflow of air into the heat exchanger 7 is required in order to sufficiently draw out the effect of arranging the electrical component unit 12 on the front side of the indoor unit.

  Therefore, in this embodiment, in the gap between the electrical component unit 12 and the heat exchanger 7, the partition member 6a partitioning them is kept at an appropriate distance so as not to contact the heat exchanger 7, The wall surface of the partition member 6a on the heat exchanger 7 side is formed almost flat.

  In other words, at least the minimum distance between the fin tip of the front lower heat exchange part 7d, which is the lowermost heat exchanger, and the partition member 6a is determined by the surface tension of the dew and the fin tip of the front lower heat exchange part 7d and the partition member. It was set to a distance that would not be bridged by dew between 6a.

  In the state where there are no obstacles around the cross-flow fan 8, the air flow that flows from the front of the cross-flow fan 8 toward the axial center of the cross-flow fan 8 is the strongest flow. This is because, in a natural state, the center of the vortex of the once-through fan 8 is generated in the vicinity of the front nose.

  However, in this embodiment, there is an electrical component unit 12 disposed at the upper portion of the air supply and ventilation duct 14 in front of the center of rotation of the once-through fan 8, and there is an air suction port on the front of the front panel 1 for convenience of design. Is not provided. Therefore, the ventilation resistance in this portion is increased, and the center of the vortex moves to the upper part of the cross-flow fan 8. However, since the vortex center is in the vicinity of the nose in the natural state, it is desired to reduce the flow resistance at the front as much as possible.

  In the present embodiment, as described above, since the minimum distance between the fin tip of the front lower heat exchange portion 7d and the partition member 6a is a distance that is not bridged by dew, there is a problem of increased channel resistance due to dew. Thus, it is possible to suppress a decrease in the heat exchange performance of the front lower heat exchanger 7d.

  Moreover, the angle of the partition member 6a was substantially matched with the angle of the front lower heat exchange part 7d which is the lowest heat exchanger. Combined with ensuring the minimum distance, the air sucked from the upper top grill 2 can reach the lowermost heat exchanger while suppressing resistance loss.

  The air velocity distribution in the lower part of the heat exchanger 7 at this time is shown in FIG. It can be determined from FIG. 3 that air has flowed to the lowest end of the heat exchanger 7.

  In addition, since the partition member 6a is disposed so as to be substantially parallel to the air suction side fin tip of the front lower heat exchange portion 7d (inclination of approximately 30 ° with respect to a plane perpendicular to the floor surface), the front surface of the dew receiving tray 9b Even if the electric component unit 12 and the air supply / ventilation duct 14 are disposed, the internal volume can be effectively used while suppressing the increase in the depth of the indoor unit and the increase in ventilation resistance. In addition, although the inclination of the partition member 6a is made parallel to the front lower heat exchange part 7d, it can be further inclined to 7 ° (inclination so that 37 ° above the plane perpendicular to the floor surface expands), It is not necessary to increase the depth of the indoor unit.

  From the above, air can flow into the lower part of the heat exchanger 7 where the electrical component unit 12 is located on the front side, and the heat exchange performance can be improved.

  As described above, according to the present embodiment, the partition member 6a interposed in the gap between the electrical component unit 12 of the indoor unit and the heat exchanger 7 has a structure in which the gap is maintained without contacting the heat exchanger 7 to the lowest end. Therefore, the inflow state of air into the heat exchanger 7 is improved, and the air conditioning performance can be improved.

  Next, a modification of the above embodiment will be described with reference to FIG. It has almost the same form from the indoor unit of the air conditioner of FIGS. 1 to 2 to its function and operation. The points already described are omitted as described above.

  The electrical component unit 12 is installed in the front portion of the indoor unit and is disposed on the lower front surface of the heat exchanger 7. In the gap between the heat exchanger 7 and the electrical component unit 12, a partition member 6 b that partitions each other is interposed. The wall surface of the partition member 6b on the heat exchanger 7 side is kept at an appropriate distance without being in contact with the heat exchanger 7, and forms a wall surface with a step.

  The lower front heat exchanging part 7d and the partition member 6b, which are the lowermost heat exchanging parts of the front face of the heat exchanger 7, are set such that the distance between them is below the distance where the above-mentioned dew is not bridged, and the distance above is higher than that. taking it. Between them, there is a gradually changing step. Note that the upper part of the partitioning member 6b is substantially parallel to the upstream end of the lower front heat exchange part, which is the lowermost heat exchanger, except for the step part.

  As described above, the cross-flow fan 8 has a large amount of suction on the front side, and has a property of trying to suck a large amount from the front side. Since this portion is widened, the channel resistance is further reduced in addition to the effects shown in the above-described embodiment.

  The air velocity distribution in the front lower heat exchange section 7d at this time is shown in FIG. It can be determined from FIG. 5 that air is flowing to the lowest end of the heat exchanger 7. From the above, air can flow into the lower part of the heat exchanger 7 where the electrical component unit 12 is located on the front side, and the heat exchange performance can be improved.

  In the air conditioner described above, in this modification, the partition member 6b interposed in the gap between the electrical component unit 12 of the indoor unit and the heat exchanger 7 is formed with a gap without contacting the heat exchanger 7 to the lowest end. While maintaining, a structure with a step was provided. Thereby, the inflow state of the air to the heat exchanger 7 is improved, and the air conditioning performance can be further improved.

  Another modification of the present embodiment is shown in FIG. The difference from the above modification is that the corners of the steps of the partition member 6b in the above modification are connected by a smooth curve.

  As a result, the air flow between the front lower heat exchange portion 7d and the partition member 6c is not slightly separated, and the air smoothly flows between the partition member 6c and the front lower heat exchange portion 7d. It flows firmly to the lowest end.
