- Fig. 1 is a diagram of the outer appearance of an air conditioner 100 according to an embodiment of the present invention.
- the air conditioner 100 is attached to an indoor wall surface or the like and is connected to an outdoor unit (which is not shown in the diagram) which is installed outside via a coolant pipe (which is not shown in the diagram). It is possible for the air conditioner 100 to also perform an automatic cleaning operation where a filter 25 and a brush 33 ( Fig. 2 ) are automatically cleaned in addition to an indoor cooling operation and an indoor heating operation.
- the air conditioner 100 is mainly provided with a casing 11, an indoor heat exchanger 13, an indoor fan 15, a bottom frame 17, the filter 25, a cleaning unit 30, a support member 40, and a suction resistance section 50 as shown in Figs. 1 to 5 .
- references which express directions such as “up”, “down”, “left”, “right”, “front surface”, and “back surface” are appropriately used, but the references express each of the directions in a state where the air conditioner 100 is installed on an indoor wall surface or the like in the state in Fig. 1 .
- the casing 11 has a box shape which is long and slender in the horizontal direction (a W direction in Fig. 1 ) as shown in Fig. 1 .
- the casing 11 forms a three dimensional space using a top surface plate 11a, a front surface plate 11b, and a back surface plate 11c as shown in Figs. 1 and 2 , and the indoor heat exchanger 13, the indoor fan 15, the bottom frame 17, the cleaning unit 30, the support member 40, and the suction resistance section 50 are accommodated in this three dimensional space.
- the top surface plate 11a mainly configures the top surface of the casing 11 and the front surface plate 11b mainly configures the front surface of the casing 11.
- an upper end of the front surface plate 11b is supported to rotate freely by a portion of the top surface plate 11a and can operate with a hinge system.
- the back surface plate 11c mainly configures the back surface of the casing 11.
- the air conditioner 100 is installed on the indoor wall surface by the back surface plate 11c being attached to an attaching plate (which is not shown in the diagram) which is installed on the indoor wall surface using a screw fastening or the like.
- a top surface suction opening 21 is provided in the top surface plate 11 a of the casing 11 from the front side across to the rear side of the top surface plate 11a. From the top surface suction opening 21, the indoor air on the vicinity of the top surface suction opening 21 is taken into the inside of the casing 11 due to driving of the indoor fan 15 and is sent to front side heat exchange sections 13a and 13b (which will be described later) and a rear side heat exchange section 13c (which will be described later) of the indoor heat exchanger 13.
- an arrow A which is a dashed line in Fig. 2 represents the flow of indoor air which is sent to the indoor fan 15 via the top surface suction opening 21 and the front side heat exchange section 13b as an example.
- the lower surface of the casing 11 is mainly configured by a bottom section 17a (which will be described later) of the bottom frame 17, and a lower surface suction opening 22 and a vent opening 23 are formed in the lower surface of the casing 11.
- the lower surface suction opening 22 is provided more to the wall side than the vent opening 23 and is linked with the inside of the casing 11 using a suction flow path 16. From the lower surface suction opening 22, the indoor air on the vicinity of the lower surface suction opening 22 is taken into the inside of the casing 11 due to driving of the indoor fan 15 and is sent to the rear side heat exchange section 13c (which will be described later) of the indoor heat exchanger 13 through the suction flow path 16.
- An arrow B which is a dotted line in Fig.
- FIG. 2 represents the flow of indoor air which is sent from the lower surface suction opening 22 to the rear side heat exchange section 13c as an example.
- the vent opening 23 is provided more to the front surface side of the air conditioner 100 than the lower surface suction opening 22 and is linked with the inside of the casing 11 using a vent flow path 18. From the vent opening 23, the indoor air is vented into a room through the vent flow path 18 after being sucked in from each of the suction openings 21 and 22 and subject to heat exchange with the indoor heat exchanger 13.
- An arrow C which is a dotted line in Fig. 2 represents the flow of indoor air which is sent from the vent flow path 18 into a room through the vent opening 23.
- the suction flow path 16 is formed from the lower surface suction opening 22 along a flow path forming section 17b (which will be described later) of the bottom frame 17.
- the vent flow path 18 is formed from the vent opening 23 along the flow path forming section 17b of the bottom frame 17. That is, the suction flow path 16 and the vent flow path 18 are positioned to be adjacent to each other to interpose the flow path forming section 17b of the bottom frame 17.
- a horizontal flap 23a is attached in the vicinity of the vent opening 23 to rotate freely with regard to the casing 11.
- the horizontal flap 23 a can be driven by a flap motor (which is not shown in the diagram) and opens and closes the vent opening 23 according to the operating state of the air conditioner 100.
- the horizontal flap 23a carries out the role of changing the vent direction of the indoor air so as to guide the indoor air which is vented from the vent opening 23 in a direction which is intended by a user.
- the indoor heat exchanger 13 is configured by a plurality of fins and a plurality of heat transfer pipes.
- the indoor heat exchanger 13 is attached to a portion of the bottom frame 17 in the inside of the casing 11.
- the indoor heat exchanger 13 performs heat exchanging between coolant and air which passes through the indoor heat exchanger 13 by functioning as an evaporator or a condenser according to the operating state of the air conditioner 100.
- the indoor fan 15 is positioned on the inside of the casing 11 and is a closed loop fan with a substantially cylindrical shape which is long and slender in the W direction shown in Fig. 1 .
- the indoor fan 15 By being driven, the indoor fan 15 generates a flow of indoor air (refer to the arrows A, B, and C which are dotted lines in Fig. 2 ) which is supplied from the vent opening 23 into a room through the indoor heat exchanger 13 after having flowed in the indoor heat exchanger 13 (in detail, the front side heat exchange sections 13a and 13b and the rear side heat exchange section 13c) due to being sucked in from each of the top surface suction opening 21 and the lower surface suction opening 22.
- a drive shaft of the indoor fan 15 is connected to an output shaft of an indoor fan motor (which is not shown in the diagram). It is possible to drive the indoor fan 15 by transferring the output of the indoor fan motor to the drive shaft of the indoor fan 15 via the output shaft when driving the indoor fan motor.
- the bottom frame 17 is configured by the bottom section 17a and the flow path forming section 17b.
- the bottom section 17a is an element which configures at least a portion of the lower surface of the casing 11 and, out of the bottom frame 17, is exposed to the outside of the air conditioner 100. As a result, a user visually can recognize the bottom section 17a in a lower surface view of the air conditioner 100.
- the flow path forming portion 17b is an element which is positioned inside of the casing 11 out of the bottom frame 17.
- the flow path forming portion 17b has a shape which extends upward from an end of the bottom section 17a and is bent along the shape of the indoor fan 15.
- the filter 25 is mainly positioned between the top surface plate 11 a of the casing 11 and the indoor heat exchanger 13, that is, on the upstream side with regard to the indoor heat exchanger 13 in the flow direction of the indoor air and is removably mounted inside the casing 11.
- the filter 25 covers the front side heat exchange sections 13a and 13b and the rear side heat exchange section 13c. Then, the filter 25 has a shape where a rear side end section 25b in the front and rear direction of the filter 25 is positioned below the apex 13d of the indoor heat exchanger 13.
- the filter 25 substantially has a so-called reverse U shape where substantially the central portion extends along the top surface plate 11 a of the casing 11 and a front side end section 25a and the rear side end section 25b in the front and rear direction cover above the indoor heat exchanger 13 by hanging down below the apex 13d of the indoor heat exchanger 13.
- the rear side end section 25b of the filter 25 reaches to a position which substantially covers the rear side heat exchange section 13c and the front side end section 25a of the filter 25 reaches to a position which completely covers the front side heat exchange section 13b and partially covers a portion of the upper section of the front side heat exchange section 13a. Due to this, a portion of the filter 25 which faces the rear side heat exchange section 13c can remove dust from the indoor air which is mainly sucked in from the lower surface suction opening 22. A portion of the filter 25 which faces the front side heat exchange sections 13a and 13b can remove dust from the indoor air which is mainly sucked in from the top surface suction opening 21. That is, the filter 25 can prevent the surface of the indoor heat exchanger 13 from becoming unclean due to dust in the indoor air.
- the cleaning unit 30 is positioned inside the casing 11 in the vicinity of the filter 25, or in more detail, in the vicinity of the folding portion at a lower section of the filter 25 as shown in Fig. 5 .
- the cleaning unit 30 is not only for cleaning the filter 25 but also performs cleaning of the brush 33 (which will be described later) which directly cleans the filter 25, and has a cleaning unit frame 31, a filter driving section 32, the brush 33, a brush driving section 34, a brush cleaning section 35, a dust receiving section 37, and a compression roller 38 as shown in Figs. 2 to 6 .
- the cleaning unit frame 31 has a long and slender shape along the longitudinal direction (the W direction in Fig. 1 ) of the air conditioner 100 as shown in Fig. 4 and the brush 33 is removably attached inside the cleaning unit frame 31.
- an opening section 31a is formed in the upper surface of the cleaning unit frame 31 as shown in Fig. 5 and the cleaning unit frame 31 is positioned further below the folding portion at the lower section of the filter 25.
- a portion of the brush 33 is exposed to the space above the cleaning unit frame 31 via the opening section 31a of the cleaning unit frame 31 and comes into direct contact with the filter 25 via the opening section 31a.
- the filter driving section 32 causes the filter 25 to travel around and is configured by a roller 32a, a roller motor (which is not shown in the diagrams), and the like.
- a fabric base which is so-called pile weave is adhered to the circumference surface of the roller 32a.
- the fabric base on the circumference surface of the roller 32a enters into the mesh of the filter 25 and it is difficult for sliding to occur between the roller 23a and the filter 25.
- the output shaft of the roller motor is connected to the rotation shaft of the roller 32a. The roller 32a rotates and the filter 25 travels around due to the roller motor being driven.
- the brush 33 has a long and slender shape along the longitudinal direction of the air conditioner 100 in the same manner as the cleaning unit frame 31 as shown in Fig. 4 and has a shape where a cross section, which is orthogonal with the longitudinal direction, is substantially a circle.
- the brush 33 removes dust from the filter 25 by coming into direct contact with the filter 25.
- the brush 33 is configured using a core material 33a and a plurality of wires 33b which are provided in the circumference surface of the core material 33a, and the wires 33b have a length so that the wires 33b come into contact with the filter 25.
- the brush 33 is provided to be able to rotate with regard to the cleaning unit frame 31.
- the brush driving section 34 is for rotating the brush 33 and is configured by, for example, a stepping motor. That is, the output shaft of the brush driving section 34 which is a motor is connected with the rotation shaft of the brush 33 and the brush 33 rotates by the stepping motor being driven. For example, moving of the filter 25 is stopped when the brush 33 is rotated, and conversely, the brush 33 is in a state where rotation is stopped when the filter 25 is moving. That is, the filter driving section 32 and the brush driving section 34 alternately can move the filter 25 or the brush 33.
- the brush cleaning section 35 is attached to the cleaning unit frame 31 as shown in Fig. 4 .
- the brush cleaning section 35 is arranged along a rotation shaft direction of the brush 33, protrudes from the back surface of the cleaning unit frame 31 toward the brush 33, and is tilted in a direction which is opposite to the rotation direction of the brush 33 (that is, the direction of the arrow in the portion of the brush 33 in Fig. 5 ). Due to this, it is possible for the brush cleaning section 35 to scrape off dust from between the wires 33b of the brush 33 in a case where the brush 33 is rotated in the direction of the arrow in Fig. 5 .
- the dust receiving section 37 is positioned below the brush 33 and the brush cleaning section 35 in a state of being attached to the cleaning unit frame 31 as shown in Figs. 2 and 5 . Dust which is scraped off from the brush 33 using the brush cleaning section 35 is retained in the dust receiving section 37. In addition, since the dust receiving section 37 is removably attached to the cleaning unit frame 31, a user can easily dispose of the dust which is retained in the dust receiving section 37 by taking out the dust receiving section 37 from the cleaning unit frame 31 and the casing 11.
- the compression roller 38 is a member with a cylindrical rod shape and is rotatably supported by the cleaning unit frame 31.
- the compression roller 38 is positioned so as to be in contact with the brush 33 in the vicinity of the brush cleaning section 35 as shown in Fig. 5 . Due to this, the compression roller 38 rotates in the opposite direction to the rotation direction of the brush 33 by following the rotation of the brush 33 when the brush is rotated in the direction of the arrow in Fig. 5 . Since dust which is retained in the dust receiving section 37 is compressed using the compression roller 38, a comparatively large amount of dust can enter the dust receiving unit 37. Furthermore, dust with comparatively high viscosity is reliably sent to the dust receiving section 37 due to rotating of the compression roller 38.
- the support member 40 is positioned above the front side heat exchange sections 13a and 13b and the rear side heat exchange section 13c as shown in Fig. 2 and supports the filter driving section 32 and the brush driving section 34 which are portions of the cleaning unit 30 as shown in Figs. 3 and 6 . Then, when the filter 25 is mounted in the air conditioner 100, the filter 25 is inserted inside of the air conditioner 100 from the front surface side of the casing 11 along the support member 40, and the support member 40 guides the filter 25 to the back surface side of the casing 11 and supports the filter 25.
- the support member 40 has a shape where a rear side end section 40b, which is an end section on the lower side of the support member 40 and an end section on the rear side of the support member 40 in the front and rear direction, is positioned below and to the rear side of the apex 13d of the indoor heat exchanger 13.
- a substantially central portion of the support member 40 extends along the top surface plate 11a of the casing 11, and the support member 40 has a shape where a front side end section 40a and the rear side end section 40b in the front and rear direction cover above the indoor heat exchanger 13 by hanging down below the apex 13d of the indoor heat exchanger 13. That is, when focusing on only the front side end section 40a and the rear side end section 40b, the support member 40 substantially has a so-called reverse U shape.
- the support member 40 has a left side portion 42 and a right side portion 43 which are positioned to interpose a partition section 41 where substantially the center of the support member 40 in the left and right direction extends in the front and rear direction, and as shown in Fig. 3 , the filter 25 which spans across the support frame is mounted onto the upper surfaces of the left side portion 42 and the right side portion 43.
- the filter 25 When being mounted into the casing 11, the filter 25 is first inserted from the front surface side of the casing 11 into the casing 11 in the state of Fig.
- the filter 25 is mounted on the upper surface of the support member 40 as shown in Fig. 3 .
- a sliding mechanism to slide the filter 25 is provided at the respective left and right end sections 42a, 42b, 43a, and 43b of the left side portion 42 and the right side portion 43 and the end surfaces of the filter 25 which spans across the support frame face each other at the respective left and right end sections 42a, 42b, 43a, and 43b of the left side portion 42 and the right side portion 43 in a front surface view of the support member 40 as shown in Fig. 6 .
- the sliding mechanism is formed using a groove, a plurality of protrusions, and the like.
- the sliding mechanism at the respective left and right end sections 42a, 42b, 43a, and 43b of the left side portion 42 and the right side portion 43 is configured to move the filter 25 on the support member 40 and this is an effective configuration not only during mounting of the filter 25 into the casing 11 but even in cases where the filter 25 is moved during cleaning of the filter 35.
- the suction resistance section 50 impedes the flow of air which is sucked in from the top surface suction opening 21 and is positioned in the vicinity of the top surface suction opening 21 which faces the rear side heat exchange section 13c as shown in Figs. 2 , 7 , and 8 .
- Fig. 7 is an enlargement of a cross section of inside the casing 11 in the vicinity of the top surface plate 11 a in Fig. 2 and the support member 40 and the filter 25 are omitted from Fig. 2 .
- Fig. 8 is a diagram of the vicinity of the top surface plate 11a in a case where the air conditioner 100 is viewed from above.
- the suction resistance section 50 is configured from a different member to the top surface plate 11a, the front surface plate 11b, and the back surface plate 11 c which configure the casing 11, and is mounted on a rear side portion 21 a of the top surface suction opening 21 which faces the rear side heat exchange section 13c. That is, the suction resistance section 50 is a different member which is positioned to the rear side and above the indoor fan 15 in the top surface suction opening 21.
- the suction resistance section 50 is a different member which is positioned above the rear side heat exchange section 13c and on the rear side of the apex 13d of the indoor heat exchanger 13 in the front and rear direction of the air conditioner 100, but not positioned toward the center of the top surface suction opening 21, and is positioned on the back surface plate 11c side.
- the rear side portion 21a of the top surface suction opening 21 is a portion from the apex 13d of the indoor heat exchanger 13 to the back surface plate 11 c of the casing 11. Accordingly, as shown in Fig.
- the materials for the suction resistance section 50 may be the same as the material for the casing 11 and composed of, for example, resin.
- the suction resistance section 50 may be composed of metal or the like.

Abstract
Description
- The present invention relates to an air conditioner, and in particular, relates to an air conditioner which is a wall mounting type.
- There are a separate type of air conditioner which is configured by an outdoor unit which is installed outside and an indoor unit which is installed indoors. In particular, as the indoor unit, there is a wall mounting type which is attached to an indoor wall surface or the like.
- Indoor units which are a wall mounting type are known as shown in, for example, PTL 1 (Japanese Unexamined Patent Application Publication No.
2001-311530 - However, environmental conditions of the locations in which the indoor units are installed differ with each location. Due to this, in the indoor unit where there are suction openings in not only the top surface but also the lower surface as shown in PTL 1, there are cases where a phenomenon occurs where air is mainly sucked in from the suction opening in the top surface and hardly any air is sucked in from the suction opening in the lower surface depending on environmental conditions at the location in which the indoor unit is installed. In particular, the indoor unit which is a wall mounting type is installed indoors at a position which is relatively close to the ceiling and the gap between the top surface of the indoor unit and the ceiling is often narrow. As a result, there is variation in the performance of the indoor unit compared to a case where performance is evaluated in a state where the gap between the top surface of the indoor unit and the ceiling is large.
- Therefore, the object of the present invention is to suppress a phenomenon, where the suction opening in the lower surface does not function, being generated depending on different circumstances due to differences in environmental conditions.
- An air conditioner according to a first aspect of the present invention is an air conditioner which is a wall mounting type and is provided with a casing, a fan, a heat exchanger, and a suction resistance section. The casing has a top surface suction opening and a lower surface suction opening. The top surface suction opening is provided from the front side across to the rear side of the top surface. The lower surface suction opening is provided in the lower surface. The fan is positioned inside the casing and generates a flow of air which is sucked in from the top surface suction opening and the lower surface suction opening. The heat exchanger is formed inside the casing by combining front side heat exchange sections and a rear side heat exchange section as a shape like an inverted V in a side surface view. The front side heat exchange sections cover the front of the fan and the rear side heat exchange section covers the rear side of the fan. The suction resistance section impedes the flow of air which is sucked in from the top surface suction opening. Furthermore, in the suction resistance section, suction resistance at a portion of the top surface suction opening which faces the rear side heat exchange section is larger than suction resistance at a portion of the top surface suction opening which faces the front side heat exchange sections. Then, the fan generates a flow of air which is sucked in from the top surface suction opening and the lower surface suction opening and flows to the rear side heat exchange section. The suction resistance section is positioned in the top surface suction opening which faces the rear side heat exchange section.
- Due to the air conditioner, the amount of indoor air which is sucked in from the top surface suction opening is suppressed due to the suction resistance section. As a result, the amount of increase in the indoor air which is sucked in from the top surface suction opening is suppressed to a certain extent due to the suction resistance section even in a case where the air conditioner is installed in environmental conditions such that there is an increase in the indoor air which is sucked in from the top surface suction opening. Accordingly, it is possible to reduce the degree of variation in the ratio of the amount of indoor air which is sucked in from the top surface suction opening and the amount of indoor air which is sucked in from the lower surface suction opening and it is possible to suppress a phenomenon, where the lower surface suction opening does not function, being generated depending on different circumstances due to differences in environmental conditions.
- An air conditioner according to a second aspect of the present invention is the air conditioner according to the first aspect of the present invention wherein the suction resistance section is positioned in a rear side portion of the top surface suction opening which faces the rear side heat exchange section.
- Due to this, the amount of indoor air which is sucked in from the rear side portion of the top surface suction opening is reduced. As a result, it is possible to further reduce the degree of variation in the ratio of the amount of indoor air which is sucked in from the top surface suction opening and the amount of indoor air which is sucked in from the lower surface suction opening.
- An air conditioner according to a third aspect of the present invention is the air conditioner according to the first aspect or the second aspect of the present invention wherein the suction resistance section is configured using a portion of the casing.
- Due to this, it is possible to configure the suction resistance section in a simple manner and costs can be limited compared to a case where the suction resistance section is formed with a different member.
- An air conditioner according to a fourth aspect of the present invention is the air conditioner according to the first aspect or the second aspect of the present invention wherein the suction resistance section is configured by a different member to the casing and is mounted in the top surface suction opening.
- Due to this, it is possible to provide the suction resistance section in a simple manner.
- An air conditioner according to a fifth aspect of the present invention is the air conditioner according to any of the first aspect to the fourth aspect of the present invention wherein the suction resistance section is provided to span across the entire length of the top surface suction opening in the longitudinal direction.
- Due to this, it is possible for the suction resistance section to close off across the entire length of the top surface suction opening in the longitudinal direction.
- An air conditioner according to a sixth aspect of the present invention is the air conditioner according to any of the first aspect to the fifth aspect of the present invention wherein the suction resistance section closes off approximately 30% or more of the rear side portion of the top surface suction opening.
- Due to this, it is possible to reduce the degree of variation in the ratio of the amount of indoor air which is sucked in from the top surface suction opening and the amount of indoor air which is sucked in from the lower surface suction opening and for the lower surface suction opening to reliably function.
- An air conditioner according to a seventh aspect of the present invention is the air conditioner according to the sixth aspect of the present invention wherein the suction resistance section closes off approximately 50% or more of the rear side portion of the top surface suction opening.
- Due to this, it is possible to further reduce the degree of variation in the ratio of the amount of indoor air which is sucked in from the top surface suction opening and the amount of indoor air which is sucked in from the lower surface suction opening.
- An air conditioner according to an eighth aspect of the present invention is the air conditioner according to any of the first aspect to the seventh aspect of the present invention wherein the speed of air which is sucked in from the lower surface suction opening is approximately 0.5 m/sec or more.
- Here, the suction resistance section impedes the indoor air which is sucked in from at least a portion of the top surface suction opening which faces the rear side heat exchange section to the extent that the speed of air which is sucked in from the lower surface suction opening is approximately 0.5 m/sec or more. Due to this, it is possible to reliably suppress the degree of variation, in the ratio of the amount of indoor air which is sucked in from the top surface suction opening and the amount of indoor air which is sucked in from the lower surface suction opening, which depends on environmental conditions in which the air conditioner is installed.

-
Fig. 1 is a diagram of the outer appearance of anair conditioner 100 according to an embodiment of the present invention. Theair conditioner 100 is attached to an indoor wall surface or the like and is connected to an outdoor unit (which is not shown in the diagram) which is installed outside via a coolant pipe (which is not shown in the diagram). It is possible for theair conditioner 100 to also perform an automatic cleaning operation where afilter 25 and a brush 33 (Fig. 2 ) are automatically cleaned in addition to an indoor cooling operation and an indoor heating operation. - The
air conditioner 100 is mainly provided with acasing 11, anindoor heat exchanger 13, anindoor fan 15, abottom frame 17, thefilter 25, acleaning unit 30, asupport member 40, and asuction resistance section 50 as shown inFigs. 1 to 5 . - Here, in the following description, references which express directions such as "up", "down", "left", "right", "front surface", and "back surface" are appropriately used, but the references express each of the directions in a state where the
air conditioner 100 is installed on an indoor wall surface or the like in the state inFig. 1 . - The
casing 11 has a box shape which is long and slender in the horizontal direction (a W direction inFig. 1 ) as shown inFig. 1 . In detail, thecasing 11 forms a three dimensional space using atop surface plate 11a, afront surface plate 11b, and aback surface plate 11c as shown inFigs. 1 and2 , and theindoor heat exchanger 13, theindoor fan 15, thebottom frame 17, thecleaning unit 30, thesupport member 40, and thesuction resistance section 50 are accommodated in this three dimensional space. Thetop surface plate 11a mainly configures the top surface of thecasing 11 and thefront surface plate 11b mainly configures the front surface of thecasing 11. Here, an upper end of thefront surface plate 11b is supported to rotate freely by a portion of thetop surface plate 11a and can operate with a hinge system. Theback surface plate 11c mainly configures the back surface of thecasing 11. Theair conditioner 100 is installed on the indoor wall surface by theback surface plate 11c being attached to an attaching plate (which is not shown in the diagram) which is installed on the indoor wall surface using a screw fastening or the like. - Then, a top
surface suction opening 21 is provided in thetop surface plate 11 a of thecasing 11 from the front side across to the rear side of thetop surface plate 11a. From the topsurface suction opening 21, the indoor air on the vicinity of the topsurface suction opening 21 is taken into the inside of thecasing 11 due to driving of theindoor fan 15 and is sent to front sideheat exchange sections heat exchange section 13c (which will be described later) of theindoor heat exchanger 13. Here, an arrow A which is a dashed line inFig. 2 represents the flow of indoor air which is sent to theindoor fan 15 via the topsurface suction opening 21 and the front sideheat exchange section 13b as an example. - In addition, the lower surface of the
casing 11 is mainly configured by abottom section 17a (which will be described later) of thebottom frame 17, and a lowersurface suction opening 22 and avent opening 23 are formed in the lower surface of thecasing 11. The lowersurface suction opening 22 is provided more to the wall side than thevent opening 23 and is linked with the inside of thecasing 11 using asuction flow path 16. From the lowersurface suction opening 22, the indoor air on the vicinity of the lowersurface suction opening 22 is taken into the inside of thecasing 11 due to driving of theindoor fan 15 and is sent to the rear sideheat exchange section 13c (which will be described later) of theindoor heat exchanger 13 through thesuction flow path 16. An arrow B which is a dotted line inFig. 2 represents the flow of indoor air which is sent from the lower surface suction opening 22 to the rear sideheat exchange section 13c as an example. Thevent opening 23 is provided more to the front surface side of theair conditioner 100 than the lowersurface suction opening 22 and is linked with the inside of thecasing 11 using avent flow path 18. From thevent opening 23, the indoor air is vented into a room through thevent flow path 18 after being sucked in from each of thesuction openings indoor heat exchanger 13. An arrow C which is a dotted line inFig. 2 represents the flow of indoor air which is sent from thevent flow path 18 into a room through thevent opening 23. - The
suction flow path 16 is formed from the lower surface suction opening 22 along a flowpath forming section 17b (which will be described later) of thebottom frame 17. Thevent flow path 18 is formed from the vent opening 23 along the flowpath forming section 17b of thebottom frame 17. That is, thesuction flow path 16 and thevent flow path 18 are positioned to be adjacent to each other to interpose the flowpath forming section 17b of thebottom frame 17. - Here, a
horizontal flap 23a is attached in the vicinity of the vent opening 23 to rotate freely with regard to thecasing 11. Thehorizontal flap 23 a can be driven by a flap motor (which is not shown in the diagram) and opens and closes the vent opening 23 according to the operating state of theair conditioner 100. Furthermore, thehorizontal flap 23a carries out the role of changing the vent direction of the indoor air so as to guide the indoor air which is vented from the vent opening 23 in a direction which is intended by a user. - The
indoor heat exchanger 13 is configured by a plurality of fins and a plurality of heat transfer pipes. Theindoor heat exchanger 13 is attached to a portion of thebottom frame 17 in the inside of thecasing 11. Theindoor heat exchanger 13 performs heat exchanging between coolant and air which passes through theindoor heat exchanger 13 by functioning as an evaporator or a condenser according to the operating state of theair conditioner 100. - In particular, the
indoor heat exchanger 13 according to the present embodiment has a shape which substantially is a shape like an inverted V in a side surface view where both ends are bent downward as shown inFig. 2 and theindoor fan 15 is positioned below theindoor heat exchanger 13. In the present embodiment, out of theindoor heat exchanger 13 which has this shape, the heat exchange sections which cover the front of theindoor fan 15 is referred to the "front sideheat exchange sections indoor fan 15 is referred to the "rear sideheat exchange section 13c" for convenience in the following description. That is, theindoor heat exchanger 13 according to the present embodiment has a shape which substantially is a shape like an inverted V where the front sideheat exchange sections heat exchange section 13c are connected at an apex 13d. - Here, a case is represented in
Fig. 2 as an example where the front sideheat exchange sections indoor fan 15. That is, the front sideheat exchange sections heat exchange section 13a) and a portion which is position above in the up and down direction (the front side heat exchange section13b). However, it is sufficient if the front sideheat exchange sections indoor fan 15 and need not be a configuration which is divided up in the up and down direction as shown inFig. 2 . - The
indoor fan 15 is positioned on the inside of thecasing 11 and is a closed loop fan with a substantially cylindrical shape which is long and slender in the W direction shown inFig. 1 . By being driven, theindoor fan 15 generates a flow of indoor air (refer to the arrows A, B, and C which are dotted lines inFig. 2 ) which is supplied from the vent opening 23 into a room through theindoor heat exchanger 13 after having flowed in the indoor heat exchanger 13 (in detail, the front sideheat exchange sections heat exchange section 13c) due to being sucked in from each of the topsurface suction opening 21 and the lowersurface suction opening 22. - A drive shaft of the
indoor fan 15 is connected to an output shaft of an indoor fan motor (which is not shown in the diagram). It is possible to drive theindoor fan 15 by transferring the output of the indoor fan motor to the drive shaft of theindoor fan 15 via the output shaft when driving the indoor fan motor. - The
bottom frame 17 is configured by thebottom section 17a and the flowpath forming section 17b. - The
bottom section 17a is an element which configures at least a portion of the lower surface of thecasing 11 and, out of thebottom frame 17, is exposed to the outside of theair conditioner 100. As a result, a user visually can recognize thebottom section 17a in a lower surface view of theair conditioner 100. - The flow
path forming portion 17b is an element which is positioned inside of thecasing 11 out of thebottom frame 17. The flowpath forming portion 17b has a shape which extends upward from an end of thebottom section 17a and is bent along the shape of theindoor fan 15. - The
filter 25 is mainly positioned between thetop surface plate 11 a of thecasing 11 and theindoor heat exchanger 13, that is, on the upstream side with regard to theindoor heat exchanger 13 in the flow direction of the indoor air and is removably mounted inside thecasing 11. Thefilter 25 covers the front sideheat exchange sections heat exchange section 13c. Then, thefilter 25 has a shape where a rearside end section 25b in the front and rear direction of thefilter 25 is positioned below the apex 13d of theindoor heat exchanger 13. In more detail, thefilter 25 according to the present embodiment substantially has a so-called reverse U shape where substantially the central portion extends along thetop surface plate 11 a of thecasing 11 and a front side end section 25a and the rearside end section 25b in the front and rear direction cover above theindoor heat exchanger 13 by hanging down below the apex 13d of theindoor heat exchanger 13. - Here, in the present embodiment, the rear
side end section 25b of thefilter 25 reaches to a position which substantially covers the rear sideheat exchange section 13c and the front side end section 25a of thefilter 25 reaches to a position which completely covers the front sideheat exchange section 13b and partially covers a portion of the upper section of the front sideheat exchange section 13a. Due to this, a portion of thefilter 25 which faces the rear sideheat exchange section 13c can remove dust from the indoor air which is mainly sucked in from the lowersurface suction opening 22. A portion of thefilter 25 which faces the front sideheat exchange sections surface suction opening 21. That is, thefilter 25 can prevent the surface of theindoor heat exchanger 13 from becoming unclean due to dust in the indoor air. - In this manner, the
filter 25 is, for example, a mesh which is plain weave or twill weave using thread made from resin, is formed in an annular shape (that is, the shape of an endless belt), and spans across a support frame (which is not shown in the diagram). Two of thefilters 25 which span across the support frame are provided to line up on the right side and the left side in a front surface view of theair conditioner 100 as shown inFig. 3 . It is not possible for thefilter 25 to maintain a stable shape by itself since reinforcing edges or ribs as are seen in typical filters are not provided in thefilter 25. As a result, thefilter 25 is held in the annular shape by spanning across the support frame. - The
cleaning unit 30 is positioned inside thecasing 11 in the vicinity of thefilter 25, or in more detail, in the vicinity of the folding portion at a lower section of thefilter 25 as shown inFig. 5 . Thecleaning unit 30 is not only for cleaning thefilter 25 but also performs cleaning of the brush 33 (which will be described later) which directly cleans thefilter 25, and has acleaning unit frame 31, afilter driving section 32, thebrush 33, abrush driving section 34, abrush cleaning section 35, adust receiving section 37, and acompression roller 38 as shown inFigs. 2 to 6 . - The
cleaning unit frame 31 has a long and slender shape along the longitudinal direction (the W direction inFig. 1 ) of theair conditioner 100 as shown inFig. 4 and thebrush 33 is removably attached inside thecleaning unit frame 31. In addition, anopening section 31a is formed in the upper surface of thecleaning unit frame 31 as shown inFig. 5 and thecleaning unit frame 31 is positioned further below the folding portion at the lower section of thefilter 25. As a result, a portion of thebrush 33 is exposed to the space above thecleaning unit frame 31 via theopening section 31a of thecleaning unit frame 31 and comes into direct contact with thefilter 25 via theopening section 31a. - The
filter driving section 32 causes thefilter 25 to travel around and is configured by aroller 32a, a roller motor (which is not shown in the diagrams), and the like. A fabric base which is so-called pile weave is adhered to the circumference surface of theroller 32a. The fabric base on the circumference surface of theroller 32a enters into the mesh of thefilter 25 and it is difficult for sliding to occur between theroller 23a and thefilter 25. The output shaft of the roller motor is connected to the rotation shaft of theroller 32a. Theroller 32a rotates and thefilter 25 travels around due to the roller motor being driven. - The
brush 33 has a long and slender shape along the longitudinal direction of theair conditioner 100 in the same manner as thecleaning unit frame 31 as shown inFig. 4 and has a shape where a cross section, which is orthogonal with the longitudinal direction, is substantially a circle. Thebrush 33 removes dust from thefilter 25 by coming into direct contact with thefilter 25. Thebrush 33 is configured using a core material 33a and a plurality ofwires 33b which are provided in the circumference surface of the core material 33a, and thewires 33b have a length so that thewires 33b come into contact with thefilter 25. In addition, thebrush 33 is provided to be able to rotate with regard to thecleaning unit frame 31. - The
brush driving section 34 is for rotating thebrush 33 and is configured by, for example, a stepping motor. That is, the output shaft of thebrush driving section 34 which is a motor is connected with the rotation shaft of thebrush 33 and thebrush 33 rotates by the stepping motor being driven. For example, moving of thefilter 25 is stopped when thebrush 33 is rotated, and conversely, thebrush 33 is in a state where rotation is stopped when thefilter 25 is moving. That is, thefilter driving section 32 and thebrush driving section 34 alternately can move thefilter 25 or thebrush 33. - The
brush cleaning section 35 is attached to thecleaning unit frame 31 as shown inFig. 4 . As shown inFig. 5 , thebrush cleaning section 35 is arranged along a rotation shaft direction of thebrush 33, protrudes from the back surface of thecleaning unit frame 31 toward thebrush 33, and is tilted in a direction which is opposite to the rotation direction of the brush 33 (that is, the direction of the arrow in the portion of thebrush 33 inFig. 5 ). Due to this, it is possible for thebrush cleaning section 35 to scrape off dust from between thewires 33b of thebrush 33 in a case where thebrush 33 is rotated in the direction of the arrow inFig. 5 . - The
dust receiving section 37 is positioned below thebrush 33 and thebrush cleaning section 35 in a state of being attached to thecleaning unit frame 31 as shown inFigs. 2 and5 . Dust which is scraped off from thebrush 33 using thebrush cleaning section 35 is retained in thedust receiving section 37. In addition, since thedust receiving section 37 is removably attached to thecleaning unit frame 31, a user can easily dispose of the dust which is retained in thedust receiving section 37 by taking out thedust receiving section 37 from thecleaning unit frame 31 and thecasing 11. - The
compression roller 38 is a member with a cylindrical rod shape and is rotatably supported by thecleaning unit frame 31. Here, thecompression roller 38 is positioned so as to be in contact with thebrush 33 in the vicinity of thebrush cleaning section 35 as shown inFig. 5 . Due to this, thecompression roller 38 rotates in the opposite direction to the rotation direction of thebrush 33 by following the rotation of thebrush 33 when the brush is rotated in the direction of the arrow inFig. 5 . Since dust which is retained in thedust receiving section 37 is compressed using thecompression roller 38, a comparatively large amount of dust can enter thedust receiving unit 37. Furthermore, dust with comparatively high viscosity is reliably sent to thedust receiving section 37 due to rotating of thecompression roller 38. - The
support member 40 is positioned above the front sideheat exchange sections heat exchange section 13c as shown inFig. 2 and supports thefilter driving section 32 and thebrush driving section 34 which are portions of thecleaning unit 30 as shown inFigs. 3 and6 . Then, when thefilter 25 is mounted in theair conditioner 100, thefilter 25 is inserted inside of theair conditioner 100 from the front surface side of thecasing 11 along thesupport member 40, and thesupport member 40 guides thefilter 25 to the back surface side of thecasing 11 and supports thefilter 25. Furthermore, thesupport member 40 has a shape where a rearside end section 40b, which is an end section on the lower side of thesupport member 40 and an end section on the rear side of thesupport member 40 in the front and rear direction, is positioned below and to the rear side of the apex 13d of theindoor heat exchanger 13. - In more detail, a substantially central portion of the the
support member 40 extends along thetop surface plate 11a of thecasing 11, and thesupport member 40 has a shape where a frontside end section 40a and the rearside end section 40b in the front and rear direction cover above theindoor heat exchanger 13 by hanging down below the apex 13d of theindoor heat exchanger 13. That is, when focusing on only the frontside end section 40a and the rearside end section 40b, thesupport member 40 substantially has a so-called reverse U shape. - Then, as shown in
Figs. 3 and6 , thesupport member 40 has aleft side portion 42 and aright side portion 43 which are positioned to interpose apartition section 41 where substantially the center of thesupport member 40 in the left and right direction extends in the front and rear direction, and as shown inFig. 3 , thefilter 25 which spans across the support frame is mounted onto the upper surfaces of theleft side portion 42 and theright side portion 43. When being mounted into thecasing 11, thefilter 25 is first inserted from the front surface side of thecasing 11 into thecasing 11 in the state ofFig. 6 and slides along the upper surfaces of theleft side portion 42 and theright side portion 43 of thesupport member 40 until the rearside end section 25b of thefilter 25 reaches the vicinity of the rearside end section 40b of thesupport member 40. Due to this, thefilter 25 is mounted on the upper surface of thesupport member 40 as shown inFig. 3 . As a result, a sliding mechanism to slide thefilter 25 is provided at the respective left andright end sections left side portion 42 and theright side portion 43 and the end surfaces of thefilter 25 which spans across the support frame face each other at the respective left andright end sections left side portion 42 and theright side portion 43 in a front surface view of thesupport member 40 as shown inFig. 6 . In detail, the sliding mechanism is formed using a groove, a plurality of protrusions, and the like. That is, the sliding mechanism at the respective left andright end sections left side portion 42 and theright side portion 43 is configured to move thefilter 25 on thesupport member 40 and this is an effective configuration not only during mounting of thefilter 25 into thecasing 11 but even in cases where thefilter 25 is moved during cleaning of thefilter 35. - The
suction resistance section 50 impedes the flow of air which is sucked in from the topsurface suction opening 21 and is positioned in the vicinity of the top surface suction opening 21 which faces the rear sideheat exchange section 13c as shown inFigs. 2 ,7 , and8 . Here,Fig. 7 is an enlargement of a cross section of inside thecasing 11 in the vicinity of thetop surface plate 11 a inFig. 2 and thesupport member 40 and thefilter 25 are omitted fromFig. 2 .Fig. 8 is a diagram of the vicinity of thetop surface plate 11a in a case where theair conditioner 100 is viewed from above. - In more detail, the
suction resistance section 50 according to the present embodiment is configured from a different member to thetop surface plate 11a, thefront surface plate 11b, and theback surface plate 11 c which configure thecasing 11, and is mounted on arear side portion 21 a of the top surface suction opening 21 which faces the rear sideheat exchange section 13c. That is, thesuction resistance section 50 is a different member which is positioned to the rear side and above theindoor fan 15 in the topsurface suction opening 21. Furthermore, in other words, thesuction resistance section 50 is a different member which is positioned above the rear sideheat exchange section 13c and on the rear side of the apex 13d of theindoor heat exchanger 13 in the front and rear direction of theair conditioner 100, but not positioned toward the center of the topsurface suction opening 21, and is positioned on theback surface plate 11c side. Here, therear side portion 21a of the topsurface suction opening 21 is a portion from the apex 13d of theindoor heat exchanger 13 to theback surface plate 11 c of thecasing 11. Accordingly, as shown inFig. 8 , the rear sideheat exchange section 13c are positioned inside thecasing 11 which faces therear side portion 21a, and the front sideheat exchange sections casing 11 which faces afront side portion 21b which is from the apex 13d of theindoor heat exchanger 13 to thefront surface plate 11b of thecasing 11. - Here, the materials for the
suction resistance section 50 may be the same as the material for thecasing 11 and composed of, for example, resin. Alternatively, thesuction resistance section 50 may be composed of metal or the like. - Then, the
suction resistance section 50 is provided to span the entire length in the longitudinal direction (that is, the W direction inFig. 1 ) of the top surface suction opening 21 in the left and right direction, and has a long and slender shape which is substantially a rectangle in the left and right direction in an upper surface view of theair conditioner 100 as shown inFig. 8 . - Here,
Figs. 2 ,7 , and8 according to the present embodiment represent a case where thesuction resistance section 50 comes into contact with theback surface plate 11c of thecasing 11 so that there are no gaps and extends to the front surface side of the casing 11 (that is, thefront surface plate 11b side of the casing 11) as an example. Furthermore,Fig. 8 expresses a case where thesuction resistance section 50 comes into contact with both a leftside end section 11d and a rightside end section 11e of thecasing 11 as an example. - In this manner, the amount of indoor air which is sucked in from the
rear side portion 21 a of the topsurface suction opening 21 is reduced due to thesuction resistance section 50 closing off therear side portion 21 a of the topsurface suction opening 21 and the indoor air which is sucked in from the top surface of thecasing 11 to inside thecasing 11 is sucked in via a portion of the top surface suction opening 21 which is mainly not closed off (in detail, thefront side portion 21b and a portion of therear side portion 21a which is not closed off). As a result, the amount of increase in the indoor air which is sucked in from the topsurface suction opening 21 is suppressed to a certain extent due to thesuction resistance section 50 even in a case where theair conditioner 100 according to the present embodiment is installed in environmental conditions such that there is an increase in the indoor air which is sucked in from the top surface suction opening 21 in a case where it is assumed that thesuction resistance section 50 is not provided. - Here, the "environmental conditions" are conditions which express in what type of environment is the location where the
air conditioner 100 is installed. As the environmental conditions, examples include, for example, that the distance between the ceiling of the room and the top surface of theair conditioner 100 is relatively narrow at the installation location of theair conditioner 100 and the like. - Here, to what extent the
suction resistance section 50 closes off therear side portion 21 a of the topsurface suction opening 21 will be described. Thesuction resistance section 50 according to the present embodiment closes off the top surface suction opening 21 to the extent that the speed of air which is sucked in from the lowersurface suction opening 22 is approximately 0.5 m/sec or more irrespective of the actual conditions of the environmental conditions in which theair conditioner 100 is installed. In detail, in a case where the area of therear side portion 21a of the topsurface suction opening 21 is 100%, thesuction resistance section 50 closes off approximately 30% or more of therear side portion 21a. Furthermore, it is preferable that thesuction resistance section 50 close off approximately 50% or more of therear side portion 21a.Figs. 2 ,7 , and8 according to the present embodiment express a case where thesuction resistance section 50 closes off approximately 60% of therear side portion 21a as an example. - Due to this, it is possible for the ratio of the amount of indoor air which is sucked in from the top
surface suction opening 21 and the amount of indoor air which is sucked in from the lower surface suction opening 22 to be reliably suppress from depending on and varying due to environmental conditions in which theair conditioner 100 is installed. Accordingly, it is possible to reduce the degree of variation in the ratio of the amount of indoor air which is sucked in from the topsurface suction opening 21 and the amount of indoor air which is sucked in from the lowersurface suction opening 22 and it is possible to suppress a phenomenon, where the lowersurface suction opening 22 does not function, being generated depending on different circumstances due to differences in environmental conditions in which theair conditioner 100 is installed. - Here, it is possible to appropriately determine the specific numerical value for what extent to which the
suction resistance section 50 closes off therear side portion 21a of the top surface suction opening 21 on the basis of calculations, simulations, experiments, or the like in further consideration of loss in pressure and the like in addition to the condition that the amount of wind from theindoor fan 15 is the lowest amount of wind, the condition that approximately 30% or more or approximately 50% or more of therear side portion 21a is closed off, and the condition that the speed of air which is sucked in from the lowersurface suction opening 22 is approximately 0.5 m/sec or more. - In addition to the above, the
air conditioner 100 is provided with an indoor control section (which is not shown in the diagram) which performs controlling of various devices which configure theair conditioner 100. The indoor control section is a microcomputer which is configured by a CPU and a memory and is accommodated in a front portion of thecasing 11. For example, the indoor control section is connected to the flap motor and the indoor fan motor, and performs control of opening and closing of thehorizontal flap 23a and control of the angle of thehorizontal flap 23a, control of the amount of wind from theindoor fan 15, and the like by performing drive control of the motors. - The top
surface suction opening 21 and the lowersurface suction opening 22 are provided in theair conditioner 100 according to the present embodiment, and the top surface suction opening 21 which faces the rear sideheat exchange section 13c is closed off using thesuction resistance section 50. Due to this, the amount of indoor air which is sucked in from the topsurface suction opening 21 is suppressed due to thesuction resistance section 50. As a result, the amount of increase in the indoor air which is sucked in from the topsurface suction opening 21 is suppressed to a certain extent due to thesuction resistance section 50 even in a case where theair conditioner 100 according to the present embodiment is installed in environmental conditions such that there is an increase in the indoor air which is sucked in from the topsurface suction opening 21 if it is assumed that thesuction resistance section 50 is not provided. Accordingly, it is possible to reduce the degree of variation in the ratio of the amount of indoor air which is sucked in from the topsurface suction opening 21 and the amount of indoor air which is sucked in from the lowersurface suction opening 22 and it is possible to suppress a phenomenon, where the lowersurface suction opening 22 does not function, being generated depending on different circumstances due to differences in environmental conditions. - Furthermore, by reducing the degree of variation in the ratio of the amount of indoor air which is sucked in from the top
surface suction opening 21 and the amount of indoor air which is sucked in from the lowersurface suction opening 22, variation in the amount of indoor air which flows to theindoor heat exchanger 13, which is caused by environmental conditions, is reduced. That is, it is possible for the amount of indoor air which flows to theindoor heat exchanger 13 to be substantially constant irrespective of environmental conditions in which theair conditioner 100 is installed. Accordingly, it is possible to prevent the performance of theair conditioner 100 differing due to the installation location. - In particular, the
suction resistance section 50 is positioned in therear side portion 21a of the top surface suction opening 21 which faces the rear sideheat exchange section 13c. Due to this, the amount of indoor air which is sucked in from therear side portion 21a of the topsurface suction opening 21 is reduced. As a result, it is possible to further reduce the degree of variation in the ratio of the amount of indoor air which is sucked in from the topsurface suction opening 21 and the amount of indoor air which is sucked in from the lowersurface suction opening 22. - In addition, the
suction resistance section 50 is configured in a simple manner using a different member to thecasing 11 and reliably closes off therear side portion 21a of the top surface suction opening 21 in thecasing 11. - In addition, the
suction resistance section 50 is provided to span across the entire length of the top surface suction opening 21 in the longitudinal direction. Due to this, it is possible for thesuction resistance section 50 to close off across the entire length of the top surface suction opening 21 in the longitudinal direction. - In addition, due to the
suction resistance section 50 closing off approximately 30% or more of therear side portion 21a of the topsurface suction opening 21, it is possible for the lower surface suction opening 22 to reliably function by reducing the degree of variation in the ratio of the amount of indoor air which is sucked in from the topsurface suction opening 21 and the amount of indoor air which is sucked in from the lowersurface suction opening 22. - In particular, due to the
suction resistance section 50 closing off approximately 50% or more of therear side portion 21a of the topsurface suction opening 21, it is possible to further reduce the degree of variation in the ratio of the amount of indoor air which is sucked in from the topsurface suction opening 21 and the amount of indoor air which is sucked in from the lowersurface suction opening 22. - In addition, in the present embodiment, the
suction resistance section 50 impedes the indoor air which is sucked in from therear side portion 21a of the top surface suction opening 21 to the extent that the speed of indoor air which is sucked in from the lowersurface suction opening 22 is approximately 0.5 m/sec or more. Due to this, it is possible to reliably suppress the degree of variation, in the ratio of the amount of indoor air which is sucked in from the topsurface suction opening 21 and the amount of indoor air which is sucked in from the lowersurface suction opening 22, which depends on environmental conditions in which theair conditioner 100 is installed. - The embodiment of the present invention has been described below based on the drawings, but the detailed configuration is not limited by the embodiment described above and modifications are possible within a scope which does not depart from the gist of the invention.
- In the embodiment described above, the
suction resistance section 50 is described as being configured using a different member to thecasing 11. However, thesuction resistance section 50 may be configured using a portion of thecasing 11. In this case, thesuction resistance section 50 is configured by, for example, thetop surface plate 11 a of thecasing 11 being extended so as to reduce the topsurface suction opening 21. - Due to this, it is possible to configure the
suction resistance section 50 in a simple manner and costs can be limited compared to a case where thesuction resistance section 50 is formed with a different member. -
Figs. 2 ,7 , and8 in the embodiment described above represent a case where thesuction resistance section 50 comes into contact with theback surface plate 11 c of thecasing 11 so that there are no gaps and extends to the front surface side of thecasing 11. However, the suction resistance opening 50 may close off at least a portion of therear side portion 21a of the top surface suction opening 21 in a state of being separated from theback surface plate 11c. - In addition,
Fig. 8 in the embodiment described above expresses a case where thesuction resistance section 50 comes into contact with both the leftside end section 11d and the rightside end section 11e of thecasing 11. However, thesuction resistance section 50 need not come into contact with and may be separated from the leftside end section 11d and/or the rightside end section 11e of thecasing 11. - In addition, the suction resistance section according to the present invention is provided in order to impede the flow of indoor air which is sucked in from the
rear side portion 21 a of the top surface suction opening 21 as described above. As a result, the suction resistance section may be provided so as to close off at least a portion of therear side portion 21 a at a position which is separated downward from thetop surface plate 11a of thecasing 11. - As above, according to the present invention, it is possible to reduce the degree of variation in the ratio of the amount of indoor air which is sucked in from a top surface suction opening and the amount of indoor air which is sucked in from a lower surface suction opening and it is possible to suppress a phenomenon, where the lower surface suction opening does not function, being generated depending on different circumstances due to differences in environmental conditions. As a result, an air conditioner according to the present invention is effective as an indoor unit which is a wall mounting type and which is installed in various environmental conditions.
