Air conditioner

Technical Field

The present invention relates to an air conditioner for cooling or heating a room.

Background

The conventional air conditioner has a structure as shown in fig. 32 to 36 as described in japanese patent laid-open No. 1997 166353. Fig. 32 is a perspective view of the air conditioner body when placed in a room, and fig. 33 is a plan view seen from below in fig. 32. Fig. 34 is a sectional view taken along the line 301-301 in fig. 33, and fig. 35 is a sectional view of a main portion seen from below in fig. 34. Fig. 36 is a plan temperature distribution diagram when the air conditioner body is placed at a corner of a room to warm the room.

The air conditioner body 1 is closely attached to a corner between a ceiling 302 and 2 directional walls 303 and 304 in a room, has a suction port on a lower side, and has a fan-shaped seat shape having an arc of 1/4 of an arc portion of the discharge port 2. When the cross-flow fan 3 is rotated by the driver 4, air is sucked from the front grill 5 serving as an inlet at the lower side, and heat is exchanged by the heat exchanger 7 provided above the water receiver 6, so that the air flows toward the arc-shaped air outlet 2 formed by the stabilizer 8 and the back guide 9. Thereby generating an air blowing effect. An internal connection pipe 11 is provided inside the air conditioner main body 1, and an air direction changing device 12 is provided in the air outlet 2. Since the outlet 2 is arc-shaped, the distances between the cross-flow fan 3 and both ends of the outlet 2 are different.

However, the above-described conventional air conditioner has the following disadvantages.

Since the air outlet 2 has an arc shape of 1/4, the length of each of the stabilizer 8 and the back guide 9 constituting the air outlet 2 is extremely short at both ends of the air outlet 2, and the distance between the cross flow fan 3 and the air outlet 2 is relatively close, so that noise is likely to be generated.

In fig. 34, when the stabilizer 8 and the back guide 9 are inclined downward, the air outlet 2 is narrowed upward as approaching both end portions from the arc-shaped central portion. Therefore, the appearance is not good, and the comfort during heating is also deteriorated.

Since the water receiver 6 is almost at a position blocking the suction port 5 near the cross-flow fan 3, the water receiver 6 becomes a resistance to air supply, and thus, abnormal sound "rattling" is easily generated by the rotation of the cross-flow fan 3 at the time of high load.

Further, since the air conditioner main body 1 is closely attached to the corners of the ceiling 302 and the walls 303 and 304 in the room, the suction port is provided on the lower side, and the discharge port is provided on the front side, the area where air is sucked is limited, and the wall attachment effect (the effect in which air flows along the wall surface) is generated. As a result, the blown air is drawn downward, and the air does not flow in the horizontal direction during cooling. In addition, the short circuit reduces the operating capability of the air conditioner, and condensation is likely to occur. On the other hand, during heating, warm air reaches only the vicinity around the air conditioner main body, and therefore the temperature distribution in the room becomes uneven, resulting in poor comfort. Fig. 36 shows the temperature distribution of the air conditioner body 1 during heating when the room is set behind the corner.

Detailed Description

An air conditioner is provided with an indoor side air blowing unit having a heat exchanger, a cross flow fan and an air outlet in a housing, the horizontal cross section of the indoor side air blowing unit being substantially circular arc, characterized in that an air flow path is formed by a stabilizer and a back guide opposed to each other in proximity to the cross flow fan, and the air flow path is provided with an outlet inclined in a substantially horizontal direction at a central portion in a longitudinal direction and further inclined downward than the central portion at both end portions. With this configuration, the air flowing along the vicinity of the wall is directed downward, and the air flowing toward the center of the living room is directed horizontally, thereby forming an air flow region having good reach. In addition, since the distance between the cross flow fan and the outlet port can be obtained, the generation of noise can be prevented. Further, since the height of the outlet port can be kept constant, the appearance is good.

The present invention provides another air conditioner including an indoor-side air blowing unit having a heat exchanger, a cross-flow fan and a substantially fan-shaped horizontal cross section in a housing, wherein an air flow path is formed by a stabilizer and a back guide opposed to each other in proximity to the cross-flow fan, and an air outlet inclined downward at both ends in a substantially horizontal direction with respect to a central portion in a longitudinal direction is provided in the air flow path. With this configuration, when the air conditioner of the present invention is installed behind the corner of the room, the air flowing along the wall is directed downward and the air flowing toward the center of the room is directed horizontally, so that the air flow easily reaches the entire room. Thus improving comfort. In addition, noise generation can be prevented. Further, since the height of the outlet port can be kept constant, the appearance is good.

In particular, in the air blowing circuit provided with a water container for treating condensed water of the heat exchanger downstream of the suction port, the back guide body is preferably provided with a 1 st projection provided at a position where a distance between the cross flow fan and the back guide body is shortest, and a 2 nd projection provided on an upstream side of the 1 st projection with respect to the air flow. With this configuration, even if the air intake balance is lost by the surge tank, the "rattling" abnormal sound generated at the time of high load can be eliminated by adjusting the amount of air sucked by the cross flow fan.

In particular, the back guide preferably includes a 1 st projection provided at a position where the distance between the cross flow fan and the back guide is shortest, and a 2 nd projection provided on the upstream side of the 1 st projection in the air flow, and an end of the 2 nd projection is larger than a central portion in the longitudinal direction of the flow path. With this configuration, the complicated flow at the end can be improved, and the "swashing" abnormal sound generated at the end can be eliminated.

In particular, it is preferable that the electric element is provided in the air blowing circuit on the downstream side of the suction port and on the upstream side of the heat exchanger. With this structure, the space can be effectively utilized. Furthermore, the electrical components can be cooled. And the existing electric elements can be used as common parts to reduce the cost.

In particular, it is preferable that a filter is provided on the downstream side of the suction port and on the upstream side of the water container. With this structure, dust in a room can be easily handled. In addition, the filter may take a material saving shape to reduce material costs.

In particular, it is preferable that a filter having a substantially L-shape is provided on the downstream side of the suction port so as to shield the heat exchanger. With this configuration, dust in a living room can be easily handled, and the filter does not become an obstacle even in the mounting work such as piping connection and drainage work, and the work is easy.

In particular, it is preferable that an opening for sucking air is provided at the top of the housing. With this configuration, the amount of air sucked in increases, and as a result, "swabable" abnormal sound generated at the time of high load can be eliminated.

The present invention provides an indoor air conditioner including a heat exchanger, a cross-flow fan, and an air outlet in a casing, wherein the cross-section of the air outlet is substantially circular, wherein a plurality of the cross-flow fans are connected by a universal joint and are disposed along the air outlet. With this configuration, the length of the cross flow fan and the area of the heat exchanger are increased, and as a result, the air conditioning performance can be improved, and the size of the air conditioner main body can be further reduced. Further, since the air is blown out from the air outlet in a wide angle, the room temperature can be made uniform quickly, and the comfort can be improved remarkably.

In another air conditioner of the present invention, an indoor-side air blowing unit having a heat exchanger, a cross-flow fan, and an air outlet in a housing, the horizontal cross section of which is substantially circular arc, is characterized in that an air direction changing device is disposed on an outer peripheral side of the air outlet to shield the air outlet and blows the air in a vertical direction by moving vertically. With this configuration, the airflow direction changing device is in a positional relationship of blocking the air outlet at a predetermined position, and the opening of the air outlet is less visible to the user. As a result, the appearance is improved. Further, since the airflow direction changing device moves up and down on the outer peripheral side of the air outlet, the vertical movement range can be increased, and the airflow direction changing range is also increased.

The present invention provides another air conditioner which can be closely attached to a ceiling and 2 directional walls in a room. The air conditioner is provided with an indoor side air supply unit having a suction port at the lower part and an air outlet, a heat exchanger and a cross flow fan at the front surface, wherein the horizontal cross section of the air outlet is approximately fan-shaped. The air outlet has an air flow path formed by a stabilizer and a back guide body facing each other in proximity to the cross flow fan. In this flow path, the horizontal center portion of the suction port has a horizontal discharge port that is oriented in a substantially horizontal direction. A front end projection having an arbitrary height is formed at a lower front end of the horizontal outlet. The two end portions of the air outlet are provided with a lower air outlet inclined downward from the central portion and a flow regulating plate extending in a substantially horizontal direction and provided at a lower front end portion of the lower air outlet.

With this configuration, the wind at the front end convex portion generates a velocity vector in the horizontal direction, and the air flowing toward the center of the room is more likely to be directed in the horizontal direction. Further, with the structure having the horizontal air outlet, the lower air outlet, and the flow regulating plate, the air flowing near the wall is directed from below to the horizontal direction, so that short-circuiting due to the wall attachment effect can be prevented, the accessibility to the entire room is improved, and as a result, comfort can be further obtained.

Particularly preferably, the air conditioner further includes a water receiver for processing condensed water disposed between the suction port and the heat exchanger.

In particular, it is preferable that a lower air outlet inclined downward at both end portions of the air outlet than at a central portion thereof and a flow regulating plate extending in a substantially horizontal direction at a lower front end portion of the lower air outlet be provided together with the horizontal air outlet. With this structure, the air flowing near the wall is directed horizontally from below. Therefore, the accessibility to the entire room is improved, and as a result, the comfort is significantly improved. Further, since the distance between the cross flow fan and the outlet is long, noise is reduced.

In particular, it is preferable that the projection portion provided at the lower surface front end portion of the horizontal air outlet and having an arbitrary height be formed of a water-absorbent material such as nonwoven fabric having water-supplying property. With this configuration, the condensed water that adheres to the vicinity of the outlet port at the time of high load is absorbed by the water absorbing material, and as a result, the condensed water is prevented from dripping into the room.

Example 1

Fig. 1 is a perspective view of an air conditioner body 1 according to an embodiment of the present invention placed in a room. And fig. 2 shows a cross-sectional view taken along the line 201-201 in fig. 1, and fig. 3 shows a cross-sectional view taken along the line 202-202. The air conditioner body 1 includes: a heat exchanger 7; a cross flow fan 3 as a blower; a grille 5 provided in the front; the air outlet 2. The outlet 2 and the grill 5 have an arc-shaped outer peripheral shape in a horizontal cross section. The outlet 2 has a flow path 2g formed by the stabilizer 8 and the back guide 9. The airflow direction changing device 12 is provided in the air outlet 2. The stabilizer 8 also functions as a water container for treating the condensate from the heat exchanger 7. The back surface of the air conditioner body 1 is mounted on a wall 303 near the ceiling 302. In this configuration, the horizontal center portion 2e of the air outlet 2 is located at a position protruding toward the center of the room, and the two end portions 2f of the air outlet 2 are located at positions close to the room wall 303.

When the cross-flow fan 3 rotates to generate an air blowing action, indoor air is sucked from the grille 5, undergoes heat exchange by the plurality of heat exchangers 7, passes through the flow path 2g, and flows toward the arc-shaped air outlet 2. The air thus heat-exchanged is sent from the air outlet 2 into the room.

In order to blow out the wind after heat exchange in a substantially horizontal direction as indicated by the arrow, as shown in fig. 2, a horizontal center portion 2e of the air outlet 2 constituted by the stabilizer 8 and the back guide 9 has a shape facing in a substantially horizontal direction. As shown in fig. 3, both ends 2f of the air outlet 2 in the horizontal direction have a shape that is lower than the central portion so that the air after heat exchange is blown out in a direction that is lower than the central portion as indicated by an arrow. The air flows from the center portion to both end portions and is gradually blown downward. With this configuration, the wind flowing along the vicinity of the wall 303 of the room is directed downward, and the wind flowing toward the center of the room is directed horizontally. That is, the air after heat exchange reaches the entire room in a three-dimensional state. Therefore, the heat-exchanged wind uniformly reaches the corners of the room, and as a result, the temperature of the entire room becomes uniform, and the comfort is significantly improved.

Example 2

Fig. 4 is a perspective view of an air conditioner body 1 according to embodiment 2 of the present invention placed in a room. Fig. 5 is a plan view seen from below in fig. 4. Fig. 6 is a sectional view taken along the line 204 and 204 in fig. 5, and fig. 7 is a sectional view taken along the line 205 and 205.

The air conditioner body 1 has a substantially fan-shaped cross section in the horizontal direction. The air conditioner body 1 is closely attached to a corner between a wall 303 and a wall 304 in a room. The air conditioner body 1 may be mounted in close contact with the ceiling 302, or may be mounted so as to create a space between the air conditioner body 1 and the ceiling 302. The air conditioner body 1 includes: a grill 5 provided on the lower surface as a suction port; a heat exchanger 7; a cross flow fan 3 as a blower; the air outlet 2. The outlet 2 has an arc-shaped outer periphery of 4 to 1 in a horizontal cross section at a corner portion between the lower side surface and the front surface. The outlet 2 has a flow path 2g formed by the stabilizer 8 and the back guide 9. The air conditioner body 1 is mounted on a wall with the height of the air outlet 2 kept horizontal. In this state, when the cross flow fan 3 rotates to generate an air blowing action, air is sucked from the grill 5, subjected to heat exchange by the plurality of heat exchangers 7, and blown from the arc-shaped air outlet 2. Thus, the air conditioner body 1 generates an air blowing action.

The air conditioner body 1 further includes: a water container 6 for treating the condensed water of the heat exchanger; a water tank 10 for treating the condensed water of the heat exchanger at the inclined portion and guiding the condensed water to the water container 6; the pipe 11 is connected to the inside. The airflow direction changing device 12 is sized to cover the air outlet 2, is provided outside the air outlet 2, and is movable in the vertical direction.

In the air outlet 2 composed of the stabilizer 8 and the back guide 9, the central portion 2e of the air outlet 2 is configured to blow air in a direction substantially horizontal as shown in fig. 6. As shown in fig. 7, both end portions 2f of the air outlet 2 are configured such that the air is blown downward. The blown air gradually changes in a three-dimensional manner downward as it approaches the two end portions 2f (the cross section along the line 205-. In this structure, air flowing near the wall faces downward, and air flowing toward the center of the room faces horizontally. As a result, the air flow after heat exchange easily reaches the entire room uniformly, and comfort is improved.

In fig. 6, each of the stabilizer 8 and the back guide 9 has a horizontal plane shape in the vicinity of the outlet of the blowout port 2 (the region indicated by "2H"). The region of the horizontal plane "2H" in fig. 6 gradually recedes to the wall side as it goes from the central portion 2e to both end portions 2f of the blowout port 2 (as it goes from the line 204 toward the line 205). The length of the horizontal plane "2H" becomes shorter from the center portion 2e to both end portions 2f of the outlet 2. In this manner, the above-described effects can be obtained by configuring the air outlet 2 in which the area or length of the horizontal plane is controlled.

Further, instead of forming the horizontal plane "2H" of the air outlet 2, the inclination of the air outlet 2 may be gradually changed downward from the central portion 2e to the both end portions 2f of the air outlet 2 (the cross section from the line 204 and the line 205). That is, the respective inclinations of the stabilizer 8 and the back guide 9 constituting the blowout port 2 are controlled to have predetermined shapes. With this configuration, the direction of the blown air gradually changes three-dimensionally from the horizontal direction downward as it approaches the both end portions 2f from the central portion 2e of the air outlet 2. As a result, the same effects as described above can be obtained.

Fig. 9(a), (b), and (c) show the positional relationship between the air blowing direction and the airflow direction changing device 12. Fig. 9(a) shows the positions of the airflow direction changing device 12 during the operation stop (no blowing) and the heating operation, and the air is blown out in a substantially downward direction. Fig. 9(c) shows the position of the airflow direction changer 12 during the cooling operation, and the air is blown out in a substantially horizontal direction. Fig. 9(b) shows an intermediate position between fig. 9(a) and 9(c), and air is blown obliquely downward. In this way, the direction of the blown air can be changed from a substantially horizontal direction to a substantially vertical direction by moving the airflow direction changing device 12 up and down. Further, since the air outlet 2 is hidden from the front when the vehicle is stopped, the opening of the air outlet 2 is not visible to the user, and as a result, the appearance is extremely excellent. Further, since the airflow direction changing device 12 vertically moves outside the air outlet 2, the vertical movement range can be expanded, and as a result, the range of the airflow direction change becomes larger.

Fig. 10 shows a planar temperature distribution of a room when the air conditioner of the present invention is disposed in a corner of the room and performs a heating operation. Fig. 36 shows the temperature distribution of a conventional air conditioner, and the temperature in the vicinity of the wall close to the air conditioner 2 is low. In contrast, in fig. 10 of the present embodiment, the temperature distribution when the air conditioner of the present invention is installed is uniform throughout the room, and the corner portions and the wall vicinity portions distant from the air conditioner main body are warmed, and the comfort is further improved.

The horizontal cross section may be substantially fan-shaped, as shown in fig. 8(a), (b), (c), or (d). That is, the shape of the air conditioner main body has a shape in which at least one shape selected from the group consisting of a square, a rectangle, a circle, and an ellipse is divided into 1/4. The present invention can be mounted on the corner portions of the adjacent walls of the room, and the direction of the air outlet can be directed toward the inside of the room. The air outlet has a substantially circular arc shape or a substantially linear shape.

Example 3

Embodiment 3 of the present invention will be described with reference to fig. 11. Fig. 11 is a cross-sectional view taken along line 204 and 204 of the central portion of the air conditioner of fig. 5. In fig. 11, the same components as those shown in fig. 6 are denoted by the same reference numerals, and description thereof is omitted. A back guide 9 forming a flow path near a cross flow fan 3 is provided with a 1 st projection 13 where the distance between the cross flow fan 3 and the back guide 9 is shortest, and a 2 nd projection 14 formed on the upstream side of the 1 st projection 13 in the air flow. The shortest distance between 2 nd projection 14 and cross flow fan 3 is longer than the shortest distance between 1 st projection 13 and cross flow fan 3. With this structure, the amount of air sucked through the cross flow fan 3 is reduced. Therefore, the balance between the amount of air sucked and the amount of air blown out is balanced, and as a result, the occurrence of abnormal noise at high load can be prevented.

Example 4

Embodiment 4 of the present invention will be described with reference to fig. 12. Fig. 12 is a perspective view of a cross section taken along line 205-205 at both ends of the air conditioner of fig. 5. The same reference numerals are given to the same components as those shown in fig. 6, and the description thereof will be omitted. The end of the 2 nd projection 14 is larger than the center of the flow channel in the longitudinal direction. In the above configuration, the complicated flow at the end portion is improved, and the "swashing" abnormal sound generated at the end portion can be eliminated.

The end portion of the 2 nd projection 14 may be formed to protrude at one side or both sides.

Example 5

Embodiment 5 of the present invention will be described with reference to fig. 13 and 14. Fig. 13 is a plan sectional view of a main portion seen from below in fig. 4. The same reference numerals are given to the same components as those shown in fig. 6, and the description thereof will be omitted. An electric element 15 is provided in a space from the downstream side of the grill 5 to the upstream side of the heat exchanger 7. Fig. 14 is a sectional view taken along the line 204 and 204 in the center portion of fig. 5, in which the electric component 15 is disposed away from the heat exchanger 7, and the influence of the air suction given to the heat exchanger 7 by the electric component is stabilized at a minimum. By providing the electric element 15 in this portion, a space can be effectively utilized, a small-sized air conditioner can be obtained, and the electric element can be cooled. In addition, the conventional electric element can be used as a common element, and the cost can be reduced.

Example 6

Embodiment 6 of the present invention will be described with reference to FIG. 15. FIG. 15 is a cross-sectional view taken along line 204-204 of the central portion of FIG. 5. The same reference numerals are given to the same components as those shown in fig. 6, and the description thereof will be omitted. A filter 16 is horizontally provided between the grill 5 serving as the suction port and the water container 6 for treating the condensed water in the heat exchanger 7. The filter 16 is divided into 2 pieces and can be easily taken out at the time of cleaning. With this filter 16, dust in a room can be easily handled. In addition, the filter may take a material saving shape, thereby reducing material costs.

Example 7

Embodiment 7 of the present invention will be described with reference to FIG. 16. Fig. 16 is a cross-sectional view taken along line 204-204 of the central portion of fig. 5. The same reference numerals are given to the same components as those shown in fig. 6, and the description thereof will be omitted. Between the grill 5 as the suction port and the water receiver 6 for processing the condensed water of the heat exchanger 7, and between the water tank 10 for processing the condensed water of the inclined heat exchanger 7 and the electric element 15, a filter 16 is provided in an L shape. Since the filter 16 is designed to surround the heat exchanger 7, dust entering from a small gap such as a pipe hole of the air conditioner body 1 can be handled without leakage. Further, by removing the grating, the pipe connection work, the drainage work, and the like are facilitated, and the work is significantly facilitated.

The filter 16 may be constituted by a plurality of filters.

Example 8

Embodiment 8 of the present invention will be described with reference to fig. 17. Fig. 17 is a plan view seen from the top side of fig. 4. A ventilation window 17 is provided on the top of the air conditioner body 1. A plurality of ventilation windows 17 are provided above the portion of the heat exchanger 7 where the internal connection pipe 11 and the electric component 15 are placed on the upstream side of the air flow. With this structure, the amount of air sucked from the gap is increased, and the air conditioning performance and the air blowing performance are improved. Further, the "swashing" abnormal sound generated at the time of high load can be eliminated.

Example 9

Embodiment 9 of the present invention will be described with reference to fig. 18. Fig. 18 is a plan sectional view of a main portion seen from below of fig. 4. The same reference numerals are given to the same components as those shown in fig. 6, and the description thereof will be omitted. The 2 cross-flow fans 3 are connected by universal joints 18 and arranged in an arc shape along the outlet port 2. With this configuration, the length of the cross flow fan 3 and the area of the heat exchanger 7 are increased. Therefore, the air conditioning performance can be improved, and the size of the air conditioner body 1 can be further reduced. In addition, since the air is blown from the air outlet at a wide angle, the comfort is improved.

Further, since more than 2 cross-flow fans 3 may be connected, the same effects as described above can be obtained in this configuration.

Example 10

Fig. 19 is a perspective view of the air conditioner body 1 according to the embodiment of the present invention placed in a room. Fig. 20 is a plan view seen from below of fig. 19. Fig. 21 is a sectional view taken along line 206 of fig. 20, and fig. 22 is a sectional view taken along line 207.

The air conditioner body 1 has a substantially fan-shaped cross section in the horizontal direction. The air conditioner body 1 is closely attached to the corners of 2-directional walls 303 and 304 adjacent to a ceiling 302 in a room. Has a suction port at the lower side and an arc-shaped portion having a blowing port 2. When the cross flow fan 3 serving as a blower rotates to generate a blowing action, air is sucked from the grill 5 at the lower surface suction port 5a, exchanges heat with the air via the plurality of heat exchangers 7, and flows into the arc-shaped air outlet 2. Thus, an air blowing action is generated. The air conditioner body 1 is provided with: a water container 6 for treating the condensed water of the heat exchanger; a water tank 10 for treating the condensed water of the heat exchanger 7 at the inclined portion and guiding the condensed water to the water container 6; an internal connection pipe 11; an air direction changing device 12.

The outlet 2 has a flow path constituted by the stabilizer 8 and the back guide 9. The outlet 2 includes: a horizontal air outlet 2a facing substantially the horizontal direction at the center in the horizontal direction; a front end convex part 2b with any height arranged at the front end of the 2H part under the horizontal blow-out port 2 a; lower air outlets 2c inclined downward at both ends in the horizontal direction than at the center; a flow straightening plate 2d extending in a substantially horizontal direction is provided at a lower surface front end portion of the lower outlet port 2 c. The horizontal portion 2H of fig. 21 has a substantially horizontal shape, and the horizontal portion 2H is located at a position gradually retreating to the wall side as it goes from the cross section of the 206-206 line of the central portion of the blowout port 2 to the cross section of the 207-207 line near both end portions. Further, the air outlet 2 gradually changes three-dimensionally downward as the cross section from the line 206-206 in the central portion to the line 207-207 in the vicinity of both ends. Further, the height of the air outlet 2 is kept horizontal.

In the horizontal air outlet 2a in the center of the air outlet 2, the air at the front end convex portion 2b has a velocity vector in the horizontal direction, and the air flowing toward the center of the room is more likely to be directed in the horizontal direction. Further, since the lower air outlet 2c inclined downward from the central portion and the flow straightening plate 2d provided at the lower air outlet 2c are provided at both end portions of the air outlet 2, short-circuiting due to the wall attachment effect can be prevented. Further, air flowing near the wall can be blown from below to a range in the horizontal direction. With this structure, the wind after heat exchange reaches the entire room. As a result, the temperature in the room is uniform, and the comfort is significantly improved.

As the air conditioner main body having a substantially fan-shaped horizontal section, a configuration shown in fig. 23 can be adopted.

Fig. 24 shows a temperature distribution on a plane of a room when the air conditioner of the present embodiment is placed in a corner of the room and a heating operation is performed. Fig. 36 shows the temperature distribution of a conventional air conditioner, and the comfort is poor because the warm air does not reach the corners of the room. On the contrary, fig. 24 shows the temperature distribution after installing the air conditioner of the present embodiment, which can achieve uniform temperature distribution, and the comfort can be remarkably improved by allowing the warm wind to reach the corners of the room.

Example 11

Another embodiment of the present invention is described with reference to fig. 25. Fig. 25 is a sectional view taken along line 206-206 of the air conditioner of fig. 20. The same reference numerals are given to the same components as those shown in fig. 21, and the description thereof will be omitted. The back guide 9 forms a flow path near the cross flow fan 3. The flow path has: a 1 st projection 13 formed at a position where a distance from the back guide 9 of the cross flow fan 3 is shortest; and a 2 nd convex part 14 formed on the upstream side of the 1 st convex part 13 with respect to the air flow. The distance between 2 nd projection 14 and cross flow fan 3 is longer than the distance between 1 st projection and cross flow fan 3. With this configuration, the amount of air sucked by the cross flow fan 3 is reduced. As a result, the air blowing performance is improved. In addition, generation of abnormal sound can be prevented.

The same reference numerals are given to the same components as those shown in fig. 21, and the description thereof will be omitted. The 2 nd convex part 14 has a shape larger at both ends than at the center. In the above configuration, the complicated flow at the end portion can be improved, and as a result, "swabable" abnormal sound generated at the end portion can be eliminated.

The end portion of the protruding portion 14 may be formed to protrude on one side or both sides, and the same effect as described above can be obtained with this structure.

Example 13

A filter 16 is horizontally provided between the grill 5 provided below the suction port and the water container 6 for treating the condensed water in the heat exchanger 7. The filter 16 is divided into 2 pieces and can be easily taken out during cleaning. Dust in a room can be easily treated by using the filter 16. Further, the construction of the internal connection pipe and the drainage construction can be easily performed only by removing the grating, and the construction becomes significantly easy.

Example 15

The same reference numerals are given to the same components as those shown in fig. 21, and the description thereof will be omitted. A filter 16 is provided in an L-shape between the grill 5 as a suction port provided on the lower side and the water container 6 for treating the condensed water of the heat exchanger 7, and between the water tank 10 for treating the condensed water of the inclined heat exchanger 7 and the electric element 15. The filter 16 is designed in a shape to enclose the surroundings of the heat exchanger 7. Therefore, the dust entering from the small gaps such as the piping hole of the air conditioner body 1 can be handled without leakage. In addition, by simply removing the grille, the internal piping connection construction, the drainage construction, and the like are facilitated, and the workability is improved.

The filter 16 may have a structure including a plurality of filters.
