Description

  The present invention relates to an air conditioner, and more particularly, to an air conditioner including a fan disposed in a fan chamber and a fan electric motor disposed outside the fan chamber.

  Conventionally, an air conditioner in which a fan chamber in which a fan is disposed is defined in a housing is known (see Patent Document 1).

  In the air conditioner according to Patent Document 1, a fan chamber and a machine chamber adjacent to the fan chamber and partitioned from the fan chamber are defined in the housing. Various parts such as a compressor are disposed in the machine room. In this air conditioner, a heat exchanger is disposed on the upstream side of the fan in the fan chamber, and after the air sucked into the fan chamber from a predetermined suction port by the fan is passed through the heat exchanger, The air is blown out from the outlet. At this time, since the fan chamber and the machine room are partitioned, air does not flow from the machine room into the fan room even if the fan is driven.

In the air conditioner according to Patent Document 1, a fan is attached to a drive shaft of a fan motor for driving the fan, and the fan motor is also disposed in the fan chamber.
JP-A-2003-106571

  By the way, in the air conditioner of Patent Document 1, the fan motor is disposed in the fan chamber. However, the fan motor may be disposed in the machine chamber, that is, outside the fan chamber. In such a configuration, the rotation shaft of the fan is disposed in the fan chamber, and the drive shaft of the fan motor is disposed outside the fan chamber. In this case, it is necessary to drive and connect the rotation shaft of the fan disposed in the fan chamber and the drive shaft of the fan motor disposed outside the fan chamber by a transmission mechanism including a belt, a chain, a gear train, or the like. In order to connect the drive shaft of the fan motor and the rotation shaft of the fan with various transmission mechanisms, a partition plate that partitions the fan chamber and the machine chamber is provided from the drive shaft of the fan motor to the rotation shaft of the fan. It is necessary to form an insertion hole for disposing the transmission mechanism.

  However, if the insertion hole is formed in the partition plate, air flows from the machine chamber into the fan chamber through the insertion hole when the fan is driven to suck air. Since the air flowing into the fan chamber from the insertion hole does not pass through the heat exchanger, the amount of air that has exchanged heat with respect to the air sucked out by the fan is reduced, that is, the amount of heat exchange is reduced.

  The present invention has been made in view of such a point, and an object of the present invention is to provide a fan motor in a configuration in which a fan electric motor is disposed outside a fan chamber, and through an opening or a gap other than a predetermined suction port from the outside. It is to prevent air from flowing into the room.

  In the present invention, the transmission mechanism (32, 62, 63) is inserted into the casing (7) by fitting the casing (7) into the opening (18b) formed in the housing (11) and facing the fan chamber (12). The transmission mechanism housing portion for housing the housing is partitioned from the fan chamber (12) to form a partition, and the flange (713) that contacts the opening edge (18a) of the opening (18b) of the housing (11) has a casing (7) The seal member (8) is pasted across the flange (713) and the opening edge (18a).

  The first invention includes a housing (11), a fan (3) disposed inside a fan chamber (12) defined in the housing (11), and an outside of the fan chamber (12). An air conditioner including a fan electric motor (6) that is disposed and drives the fan (3) is an object. The fan (3) is provided at one end of the rotating shaft (31) and one end of the driving shaft (61) of the fan electric motor (6), and the driving force of the fan electric motor (6) is supplied to the fan (3) and the transmission mechanism (32, 62, 63) and the opening (18b) formed in the housing (11) to divide the fan chamber (12) to partition the transmission mechanism (32, 62, 63) and a body part (71) defining a transmission mechanism housing chamber (16), and an opening edge part of the opening (18b) provided integrally with the outer periphery of the body part (71) ( 18a) a casing (7) having a flange (713) that abuts from the outside of the housing (11), and a seal applied across the flange (713) and the opening edge (18a) A member (8) is further provided.

  In the case of the above configuration, the transmission mechanism (32, 62, 63) is disposed by partitioning the transmission mechanism storage chamber (16) with the fan chamber (12) by the casing (7). Air can be prevented from flowing into the fan chamber (12) from the outside of the fan chamber (12) through the space.

  The casing (7) that defines the transmission mechanism storage chamber (16) is fitted into an opening (18b) formed in the housing (11), and the casing (7) has a flange (713) By sticking the seal member (8) across the opening edge (18a) of the opening (18b), the gap is formed between the casing (7) and the opening (18b) of the housing (11) from the outside. Air can be prevented from flowing into the fan chamber (12).

  Here, as another configuration for sealing between the casing (7) and the opening (18b) of the apparatus main body, a seal member (8) is attached to the inner peripheral portion of the opening (18b) of the housing (11), A structure that seals between the outer peripheral surface of the casing (7) and the inner peripheral portion of the opening (18b) (for example, a guide portion formed by bending in the housing (11) is provided at the opening edge of the housing (11)) In addition, a configuration in which a seal member (8) is attached to the inner peripheral surface of the guide portion to seal between the outer peripheral surface of the casing (7) and the inner peripheral surface of the guide portion (see FIG. 5)) is conceivable. . However, in such a configuration that seals with the outer peripheral surface of the casing (7), the size of the opening (18b) through which the casing (7) is inserted (the size of the inner peripheral surface of the guide portion) is attached to the seal member (8). Therefore, when the casing (7) is fitted into the guide portion, the seal member (8) needs to be fitted while being pressed and deformed. That is, a certain amount of force is required when fitting the casing (7), and workability is very poor. Furthermore, when the casing (7) is fitted, the seal member (8) may be damaged.

  On the other hand, according to the present invention, the sealing member (8) is not the inner periphery of the opening (18b) of the housing (11), but the flange (713) and the opening edge (18a) of the casing (7). By sticking across the cover, a gap can be provided between the casing (7) and the opening (18b), so that the workability when the casing (7) is fitted into the opening (18b) can be improved. In addition, there is no possibility of damaging the seal member (8) when the casing (7) is fitted into the opening (18b).

  According to a second invention, in the first invention, a heat exchanger (2) is provided on the suction side of the fan (3).

  In the case of the above configuration, from the outside of the fan chamber (12) through the space where the transmission mechanism (32, 62, 63) is disposed and the gap between the casing (7) and the opening (18b) of the housing (11). Since air is prevented from flowing into the fan chamber (12), the fan (3) can be prevented from sucking air that has not passed through the heat exchanger (2). That is, it is possible to prevent the amount of air exchanged by the heat exchanger (2) from decreasing with respect to the amount of air sucked by the fan (3).

  A third invention is the box according to the first or second invention, wherein the body (71) of the casing (7) is recessed inward of the housing (11) and opened outward of the housing (11). The casing (7) further includes a lid member (72) that closes the opening of the main body (71), and the lid member (72) includes the seal member (8) as the flange. It is assumed that it is attached to the main body (71) or the housing (11) while being sandwiched with (713).

  In the case of the above configuration, the seal member (8) is not only a seal between the flange (713) of the casing (7) and the opening (18b) of the housing (11), but also the main body of the casing (7). Sealing between the part (71) and the lid member (72) can be performed. As a result, one seal member (8) seals two places between the casing (7) and the opening (18b) and between the main body (71) and the lid member (72) of the casing (7). And the number of parts can be reduced.

  According to the present invention, the transmission mechanism (32, 62, 63) is disposed by partitioning the fan chamber (12) and the transmission mechanism storage chamber (16) with the casing (7). Air can be prevented from flowing in from the outside of the fan chamber (12) through the space formed, and the flange (713) of the casing (7) and the opening edge (18a) of the opening (18b) By sticking the seal member (8) across the wall, air can be prevented from flowing into the fan chamber (12) from the gap between the casing (7) and the opening (18b) of the housing (11). . Furthermore, the casing (7) is opened by sticking the seal member (8) across the flange (713) of the casing (7) and the opening edge (18a) of the opening (18b) of the housing (11). The workability at the time of fitting into (18b) can be improved, and the possibility of damaging the seal member (8) when the casing (7) is fitted into the opening (18b) can be eliminated.

  According to the second invention, by preventing air from flowing into the fan chamber (12) in which the fan (3) provided on the downstream side of the heat exchanger (2) is disposed, It is possible to prevent the amount of heat exchange from being reduced by sucking air that does not pass through the exchanger (2).

  According to the third invention, the lid member (72) of the casing (7), the body (71) of the casing (7) or the housing with the seal member (8) sandwiched between the flange (713) (11) by attaching the sealing member between the body (71) and the lid member (72) of the casing (7) to the opening edge of the opening (18b) of the casing (7) and the housing (11). The sealing member (8) that seals between (18a) can also be used, and as a result, the number of parts can be reduced.

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

  The front plate (11a) is provided in a substantially upper half on the front side of the housing (11), and a partition plate (14) is connected to a lower end edge thereof. The partition plate (14) extends obliquely downward from the lower end edge of the front plate (11a) toward the back side, and is approximately 2/3 of the depth of the housing (11) from the front plate (11a) toward the back side. It bends and extends vertically downward at the position. Thus, from the upper side to the back side in the housing (11), the front plate (11a), the back plate (11b), the left side plate (11c), the right side plate (11d), the top plate (11e), the base (10) and A fan chamber (12) surrounded by the partition plate (14) is partitioned. The fan chamber (12) formed in this way is kept airtight so as to prevent the inflow and outflow of air from other than the inlet (12a) and the outlet (12b).

  The evaporator (2) and the fan (3) are disposed in the fan chamber (12).

  Although the detailed structure of the evaporator (2) is not shown, it is a plate fin coil type air heat exchanger, and is disposed on the back side of the fan chamber (12) so as to close the suction port (12a). Has been. An air filter (15) is attached to the back plate (11b) of the housing (11) so as to cover the suction port (12a). That is, the air sucked into the fan chamber (12) from the suction port (12a) is first removed of dust by the air filter (15) and then cooled by the evaporator (2).

  The fan (3) is disposed in the fan casing (30), and its rotating shaft (31) extends horizontally in the left-right direction. The rotary shaft (31) is rotatably supported by bearings (31a, 31a) installed in the housing (11), and a fan-side pulley (32) is attached to one end thereof. ing. The fan casing (30) has an air outlet connected to the air outlet (12b) of the housing (11). A duct (9) extending to the cabin (not shown) is attached to the upper surface plate (11e) in which the air outlet (12b) is formed, and the air blown from the fan casing (30) It is fed into the duct (9) via 12b).

  On the other hand, a machine installation space (13) is formed below and on the front side of the fan chamber (12). The machine installation space (13) is partitioned by the partition plate (14) on the upper and back sides, and the left and right side surfaces are partitioned by the left side plate (11c) and the right side plate (11d), and is open to the front side. Has been. In this machine installation space (13), a compressor (4), a condenser (5), an expansion valve, an electric motor for fan (6) and the like are arranged.

  Although the detailed structure is not shown, the condenser (5) is a water heat exchanger that performs heat exchange between the pumped seawater and the refrigerant.

  The fan motor (6) has a drive shaft (61) extending in parallel with the rotation shaft (31) of the fan (3), and an electric motor side pulley (62) at one end of the drive shaft (61). Is attached.

  A V-belt (63) is wound around the fan-side pulley (32) of the fan (3) and the motor-side pulley (62) of the fan motor (6). The drive power of the fan electric motor (6) is transmitted to the fan (3). The fan side pulley (32), the motor side pulley (62) and the V belt (63) constitute a transmission mechanism.

  The air conditioner (1) configured as described above drives the fan (3) by the fan electric motor (6) and from the outside of the housing (11) through the suction port (12a) to the fan chamber (12). Inhale air. The air sucked at this time is removed by passing through the air filter (15) and is cooled by passing through the evaporator (2). Thus, the purified and cooled air is sucked into the fan (3), blown out from the outlet of the fan casing (30), and supplied to the cabin or the like through the duct (9).

  Next, the belt chamber (16) that houses the fan side pulley (32), the motor side pulley (62), and the V belt (63) will be described. On the left side of the housing (11), a belt chamber (16) adjacent to the fan chamber (12) and protruding from the fan chamber (12) to the machine installation space (13) is defined. This belt chamber (16) constitutes a transmission mechanism storage chamber.

  The belt chamber (16) is defined by a casing (7) provided so as to be immersed in the housing (11). The casing (7) includes a box-shaped casing main body (71) whose one surface is open and a lid member (72) (see FIG. 4) for closing the opening of the casing main body (71). A belt chamber (16) is formed in the belt. FIG. 3 shows the casing body (71), (a) shows a front view, and (b) shows a side view.

  The casing body (71) includes a bottom plate (711) having a pentagonal shape when viewed from the front, and five peripheral plates (712, 712,...) That are provided upright from the peripheral edge of the bottom plate (711) and surround the bottom plate (711). ).

  When the casing body (71) is fitted into the housing (11), the bottom plate (711) has a fan insertion hole (through which the rotation shaft (31) of the fan (3) and the fan side pulley (32) are inserted ( 714) and a motor insertion hole (715) through which the drive shaft (61) of the fan motor (6) and the motor side pulley (62) are inserted are formed. Further, a plurality of lower holes (not shown) for tapping screws for attaching partition plates (716, 716) to be described later are provided around the fan insertion hole (714) in the bottom plate (711). 714).

  In addition, a flange (713) that bends and extends outward from the casing main body (71) is provided on the edge of each peripheral plate (712) opposite to the bottom plate (711), that is, on the opening side.

  On the other hand, an opening (17) is formed in the left side plate (11c) of the housing (11). The opening (17) opens the fan chamber (12) and the machine installation space (13) to the outside of the housing (11) in the left side plate (11c). As shown in FIG. 4, the opening (17) is provided with a stay (18) over the periphery thereof. The stay (18) extends in parallel with the left side plate (11c) and is attached to the outer side surface of the left side plate (11c), and the housing (11) inward from the inner end of the attachment unit (18a) It is comprised by the bending part (18b) extended and bent to the shape, and is carrying out the L-shaped cross section. An opening into which the casing body (71) is fitted is formed by the bent portion (18b) of the stay (18), and the mounting portion (18a) of the stay (18) constitutes an opening edge of the opening. The opening formed by the bent portion (18b) is a pentagon slightly larger than the pentagon formed by the peripheral plates (712, 712,...) Of the casing body (71).

  As shown in FIG. 4, the casing body (71) has a bottom plate (711) inside the housing (11), that is, a fan chamber (12) at an opening formed by the bent portion (18b) of the stay (18). ) So that it is located inside. The casing body (71) is fitted into the opening up to a position where the flanges (713, 713,...) Contact the stay (18). At this time, since a gap is provided between the peripheral plate (712, 712,...) Of the casing body (71) and the stay (18), the casing body (71) can be fitted smoothly.

  At this time, the V-belt (63) is not wound around the fan-side pulley (32) and the motor-side pulley (62), and the fan-side pulley (32) and the motor-side pulley (62) are inserted into the fan respectively. It passes through the hole (714) and the motor insertion hole (715) and is arranged in the casing body (71), that is, in the belt chamber (16). That is, the fan insertion hole (714) and the motor insertion hole (715) have inner diameters that allow the fan-side pulley (32) and the motor-side pulley (62) to pass through, respectively.

  The partition plate (14) has a notch (notched) so that a casing (7) that immerses in the housing (11) straddles the fan chamber (12) and the machine installation space (13). (Not shown) is formed. That is, since the casing (7) accommodates not only the fan side pulley (32) but also the motor side pulley (62), the casing (7) protrudes from the fan chamber (12) to the machine installation space (13). Thus, in order to immerse the casing (7) protruding into the machine installation space (13) into the fan chamber (12), the fan chamber (12) and the machine installation space (13) are separated from each other. It is necessary to provide a notch for avoiding interference with the casing (7) in the partition plate (14). However, in the configuration in which a notch is provided in the partition plate (14) and the casing (7) is fitted into the notch, the space from the machine installation space (13) through the gap between the notch and the casing (7) There is a risk of air flowing into the fan chamber (12). Therefore, a seal member (not shown) is provided between the notch and the bottom plate (711) and the peripheral plates (712, 712) of the casing body (71) to seal the gap between the notch and the casing (7). ing. This prevents air from flowing from the machine installation space (13) into the fan chamber (12) through the gap between the notch and the casing (7).

  After the casing body (71) is fitted in the opening formed by the bent portion (18b) of the stay (18), the seal is straddled across the flange (713, 713,...) And the mounting portion (18a) of the stay (18). A member (8) is affixed. By doing so, the gap between the casing body (71) and the opening formed by the bent portion (18b) is sealed.

  After the casing body (71) is fitted into the opening, the partition plates (716, 716) are attached to the bottom plate (711) of the casing body (71) so as to close the fan insertion hole (714). This partition plate (716, 716) is a pair of plate members, and each partition plate (716) has a semicircular cutout portion (inner diameter slightly larger than the outer diameter of the rotating shaft (31) of the fan (3)). 717) is formed (see FIG. 3). The partition plates (716, 716) are attached to the bottom plate (711) by tapping screws so as to surround the rotating shaft (31) with the notches (717, 717). By doing so, it is possible to suppress as much as possible the flow of air from the belt chamber (16) into the fan chamber (12).

  Thus, after the partition plates (716, 716) are attached, the V-belt (63) is wound around the fan-side pulley (32) and the motor-side pulley (62).

  Finally, the lid member (72) of the casing (7) is attached. The lid member (72) is attached to the stay (18) in a state where the seal member (8) is sandwiched between the flanges (713, 713,...).

  Thus, the belt chamber (16) that is adjacent to the fan chamber (12) and protrudes from the machine installation space (13) is defined by the casing (7) fitted into the opening of the left side plate (11c) in the housing (11). It is formed.

-Effect of the embodiment-
According to the embodiment, in the air conditioner (1) in which the fan (3) is disposed in the fan chamber (12), and the fan motor (6) is disposed outside the fan chamber (12). By separating the belt chamber (16) adjacent to the fan chamber (12) and protruding into the machine installation space (13) from the fan chamber (12) by the casing (7), a V-belt (63 It is possible to prevent air from flowing from the machine installation space (13) into the fan chamber (12) through the space in which the transmission mechanism is provided.

  Further, a seal is provided across the opening edge of the opening of the left side plate (11c) into which the casing (7) is fitted (the mounting portion (18a) of the stay (18)) and the flange (713, 713,...) Of the casing (7). Even if the casing (7) that defines the belt chamber (16) is fitted into the housing (11) by attaching the member (8), the casing (7) and the opening (bending of the stay (18)) The air can be prevented from flowing into the fan chamber (12) from the outside through a gap with the portion (18b)).

  Thus, when the fan (3) is driven by preventing air from flowing into the fan chamber (12) from the outside such as the machine installation space (13), the suction port ( Air can be prevented from flowing in from other than 12a). As a result, air can be prevented from flowing into the fan chamber (12) without passing through the evaporator (2), and cooled by the evaporator (2) with respect to the amount of air sucked by the fan (3). It is possible to prevent a decrease in the amount of air, that is, a decrease in the amount of heat exchange.

  After the casing (7) is fitted into the opening (bent portion (18b)) of the housing (11), the flange (713, 713,...) And the stay (18) mounting portion from above the flange (713, 713,...) By sticking the seal member (8) across (18a), workability when the casing (7) is fitted into the opening (bent portion (18b)) can be improved. In other words, as a configuration for sealing between the casing (7) and the opening (bent portion (18b)), the inner peripheral surface of the bent portion (18b) of the stay (18) as in the comparative example shown in FIG. A configuration is conceivable in which the seal member (81) is attached and the space between the inner peripheral surface of the guide portion extending inward of the stay (18) and the outer peripheral surface of the casing (7) is sealed by the seal member (81). However, in such a configuration, when the casing (7) is fitted, the bent portion (18b) after the sealing member (81) is attached to ensure sealing with the outer peripheral surface of the casing (7). The size of the opening is slightly smaller than the pentagonal shape formed by the peripheral plates (712, 712,...) Of the casing (7). For this reason, when the casing (7) is fitted, the sealing member (81) must be fitted while being pressed and deformed, and a force is required for fitting the casing (7), resulting in poor workability. Further, when the casing (7) is fitted, the seal member (81) may be damaged. However, according to this embodiment, the flange (713, 713,...) And the stay of the casing (7) are not between the outer peripheral surface of the casing (7) and the inner peripheral surface of the bent portion (18b) of the stay (18). Since the sealing member (8) is applied across the mounting portion (18a) of (18), the sealing member (8) is not attached when the casing (7) is fitted, and the casing (7) After the fitting, the seal member (8) is pasted. As a result, the casing (7) can be fitted smoothly, and the possibility of damaging the seal member (8) can be eliminated.

  Furthermore, in addition to the space between the casing (7) and the stay (18), it is necessary to seal between the casing body (71) of the casing (7) and the lid member (72). Between the bent part (18b) of the stay (18) and the stay (18) is a seal member (81), and between the casing body (71) and the lid member (72) is the attachment part (18a) of the stay (18) It is sealed with another sealing member (82) affixed to. However, according to the present embodiment, the casing main body (71) is provided by the sealing member (8) pasted between the flanges (713, 713,...) Of the casing (7) and the mounting portion (18a) of the stay (18). And the lid member (72) can also be sealed, so that the number of parts can be reduced by using a common seal member.

Although the opening into which (7) is fitted is configured and the opening edge of the opening is configured by the mounting portion (18a) of the stay (18), the present invention is not limited to this. That is, the stay (18) is not necessarily provided, and the casing (7) may be fitted into the opening (17) of the left side plate (11c) where the stay (18) is not provided. In such a case, the flanges (713, 713,...) Of the casing (7) come into contact with the opening edge of the opening (17) formed in the left side plate (11c). That is, the opening (17) constitutes an opening into which the casing (7) is fitted, and the opening edge portion of the opening (17) constitutes an opening edge portion with which the flanges (713, 713, ...) abut.

  Further, in the above embodiment, the air conditioner (1) is configured exclusively for cooling, but on the upstream side of the fan (3), not the evaporator (2) but the condenser (5) is provided for heating. It may be configured exclusively, or may be an air conditioner (1) capable of switching between cooling and heating.

  In the above embodiment, the fan electric motor (6) is arranged in the machine arrangement space (13) surrounded by the partition plate (14) and the left and right side plates (11c, 11d). As long as it is outside the chamber (12), it may be disposed anywhere. In such a case, the casing (7) defining the belt chamber (16) does not protrude from the fan chamber (12) to the machine installation space (13), but the fan motor (6) from the fan chamber (12). It protrudes to the space side where is disposed.

  Further, in the embodiment, the seal member (8) seals between the flanges (713, 713,...) Of the casing (7) and the opening edge of the opening (17), and the casing body (71) and the lid member. (72) is sealed, but the present invention is not necessarily limited to this, and each may be configured to be sealed with another sealing member. However, the configuration in which both the gaps are sealed with one seal member (8) as in this embodiment is preferable because the number of parts can be reduced.

  In the embodiment, the driving force of the fan motor (6) is transmitted to the fan (3) via the motor side pulley (62), the V belt (63), and the fan side pulley (32). However, it is not limited to this. For example, the drive shaft (61) of the fan motor (6) and the rotation shaft (31) of the fan (3) may be connected by a gear train composed of a plurality of gears, or the drive shaft ( A configuration may be adopted in which a chain is wound around and connected to the sprocket provided in 61) and the sprocket provided in the rotating shaft (31).

  In addition, the above embodiment is an essentially preferable illustration, Comprising: It does not intend restrict | limiting the range of this invention, its application thing, or its use.
