Description




TECHNICAL FIELD




The present invention relates to an air conditioner which is hung on a wall in a room. More particularly, it relates to a wind direction adjusting mechanism which appropriately changes over the wind direction of air blown from an air outlet at the cooling time and the heating time.




BACKGROUND ART




Cold air accumulates on the floor side, and warm air accumulates on the ceiling side. Therefore, an air conditioner should change over the wind direction of blown air at the cooling time and the heating time to provide a comfortable temperature environment in a room. For this purpose, the air conditioner is provided with wind direction adjusting means at an air outlet. One example of the prior art will be described with reference to

FIGS. 8A and 8B

.




An air conditioner shown in

FIGS. 8A and 8B

is a wall-mounted one that is intended to be mounted at a high position on a wall in a room, for example, at a position near a ceiling. This air conditioner has a base plate


1


which is fixed on the wall surface with screws or the like and a housing including an exterior panel


2


supported on the base plate


1


. Although not shown definitely in

FIG. 8

because it is a sectional view, the base plate


1


is provided with a pair of right and left side plates bent at a right angle from both ends of the base plate


1


.




In this example of prior art, the exterior panel


2


includes an upper panel


21


which is increasingly curved downward to the front (in the direction away from the wall) and a lower panel


22


increasingly curved upward to the front, and the front ends of these panels are connected to each other.




The upper panel


21


is formed with an air inlet


210


in a grille form, and the lower panel


22


is formed with an air outlet


220


. A heat exchanger


3


and an air blower


4


consisting of a cross-flow fan are arranged in an air passage connecting the air inlet


210


to the air outlet


220


in the housing.




In this example of prior art, the heat exchanger


3


includes a front-side heat exchanger


31


and a rear-side heat exchanger


32


, which are connected to each other in a Λ shape, and dip plates


33


and


34


are disposed under these heat exchangers


31


and


32


, respectively. The heat exchanger


3


and the air blower


4


are supported between the side plates of the base plate


1


.




In the air outlet


220


, there are provided a plurality of transverse wind deflectors


230


for changing the wind direction in the transverse direction and a first vertical wind deflector


231


and a second vertical wind deflector


232


for changing the wind direction in the vertical direction. The vertical wind deflectors


231


and


232


are turned around support shafts


231




a


and


232




a


, respectively, which are provided almost horizontally in the air outlet


220


. The wind deflectors


230


,


231


and


232


are rotatably reciprocated by a motor, not shown.




An air passage extending from the air blower


4


to the air outlet


220


is formed by the bottom surface of the drip plate


33


arranged on the front side and a back-side wind introducing surface


101


provided on the base plate side.




At the rear edge of the air outlet


220


connecting with the back-side wind introducing surface


101


, a diffuser


233


for changing the opening area of air outlet is provided so as to be capable of being opened and closed. The diffuser


233


is rotatably reciprocated around a support shaft


233




a


arranged in parallel with the support shaft


231




a


, and is provided with a motor


233




b


serving as a driving source.




At the time of cooling operation, as shown in

FIG. 8A

, the first and second vertical wind deflectors


231


and


232


and the diffuser


233


are at a substantially horizontal position, so that a cold air flow A which has been cooled in the heat exchanger


3


and blown from the air blower


4


is blown out in the substantially horizontal direction through the air outlet


220


toward the ceiling surface side in the room.




At the time of heating operation, as shown in

FIG. 8B

, the first and second vertical wind deflectors


231


and


232


and the diffuser


233


are turned in the counterclockwise direction, so that a warm air flow B which has been warmed in the heat exchanger


3


and blown from the air blower


4


is blown out in the slantwise downward direction or in the substantially vertical downward direction through the air outlet


220


toward the floor surface side in the room.




Thus, the wind direction is changed at the cooling operation time and the heating operation time. Nevertheless, the prior art suffers from a problem as described below at the time of heating operation.




At the time of heating operation, the first and second vertical wind deflectors


231


and


232


are opened as shown in

FIG. 8B

, but a gap is formed between the bottom surface of the drip plate


33


forming the air passage and the second vertical wind deflector


232


. Therefore, some of the warm air flow B passes through this gap and leaks to the ceiling surface side as indicated by arrow mark B′, so that the heating efficiency decreases accordingly.




SUMMARY OF THE INVENTION




Thereupon, an object of the present invention is to blow almost all of a warm air flow toward a floor surface without leakage on the ceiling surface side at the heating operation time in an air conditioner having a vertical wind deflector in an air outlet.




To solve the above problem, the present invention provides an air conditioner having a housing including a base plate fixed to a wall in a room and an exterior panel supported on the base plate, the exterior panel being provided with an air inlet on the upper surface side thereof and an air outlet on the lower surface side thereof, and the housing containing a heat exchanger and an air blower in an air passage connecting the air inlet to the air outlet, in which on the front side of the air outlet, a recess with a predetermined depth, which is depressed toward the inside of the housing, is formed so as to connect with the air passage, and in the recess, a vertical wind deflector which turns in the up-and-down direction around a horizontal rotating shaft and a support frame which supports the vertical wind deflector are arranged; the support frame has a rotating shaft on the rear edge side close to the air passage, and is pivotally supported by a side plate of the recess via the rotating shaft, and a front edge of the support frame is urged toward the recess by a first spring; in a state in which the vertical wind deflector is arranged on the lower surface side of the support frame, the front edge thereof is rotatably supported on the front edge side of the support frame via predetermined pivotally supporting means, and a rear edge of the vertical wind deflector is urged toward the lower surface side of the support frame by a second spring; the support frame is provided with driving force transmitting means including an input shaft, which is connected to a motor mounted on the side plate side of the recess and is rotatably inserted in the rotating shaft, and an output shaft, which is connected to the input shaft via predetermined mechanical connecting means and gives a rotation driving force of the motor to the vertical wind deflector; at the cooling operation time, the motor is rotated in the direction against the urging force of the first spring to open the front edge sides of the support frame and the vertical wind deflector integrally; and at the heating operation time, the motor is rotated in the direction against the urging force of the second spring to open only the front edge side of the vertical wind deflector.




Also, the present invention embraces a mode, as another feature, such that a diffuser is provided at a rear edge of the air outlet so as to be capable of being opened and closed, and the diffuser is provided with a transverse wind deflector.




Further, the present invention embraces a mode such that the vertical wind deflector is a second vertical wind deflector, and a first vertical wind deflector is disposed on the rear edge side in the air outlet so as to be adjacent to the second vertical wind deflector. In this case, the longitudinal width of the second vertical wind deflector is preferably larger than the longitudinal width of the first vertical wind deflector.




Also, another feature of the present invention is that the upper end surface of the recess is formed into an arcuate shape along the turning path of the front edge side of the vertical wind deflector.




In the present invention, as the mechanical connecting means connecting to the input shaft and the output shaft, an odd number of intermediate gears or a connection belt is preferably used.




Also, the present invention embraces a mode such that the driving force transmitting means is housed in a gear box consisting of a box body in which a side face formed integrally with the support frame is open and a lid body installed detachably to the opening of the box body.




From the viewpoint of design, it is preferable that in the operation stop state, the vertical wind deflector be included in a part of outside shape of the housing so as to hide the recess.

DETAILED DESCRIPTION




An embodiment of the present invention will now be described with reference to

FIGS. 1

to


7


. The present invention is not limited to the embodiment described below. In these figures, the same reference numerals are applied to elements that are the same or can be regarded as the same as the elements of the prior art described with reference to

FIG. 8

before.




First, the construction of a housing can be the same as that of the prior art described before. Specifically, in the present invention as well, the housing has a base plate


1


and an exterior panel


2


, and the exterior panel


2


includes an upper panel


21


and a lower panel


22


.




The upper panel


21


is formed with an air inlet


210


, and the lower panel


22


is provided with an air outlet


220


.




In an air passage connecting the air inlet


210


to the air outlet


220


in the housing, a heat exchanger


3


and an air blower


4


are arranged. The heat exchanger


3


includes a front-side heat exchanger


31


and a rear-side heat exchanger


32


, and drip plates


33


and


34


are disposed under these heat exchangers


31


and


32


, respectively.




An air passage extending from the air blower


4


to the air outlet


220


is formed by the bottom surface of the drip plate


33


arranged on the front side and a back-side wind introducing surface


101


provided on the base plate


1


side.




At the rear edge of the air outlet


220


connecting with the back-side wind introducing surface


101


, a diffuser


233


for changing the opening area of air outlet is provided so as to be capable of being opened and closed. The diffuser


233


is rotatably reciprocated around a support shaft


233




a


arranged in parallel with a support shaft


231




a


, and is provided with a motor


233




b


serving as a driving source.




In the present invention, the diffuser


233


is provided with a plurality of transverse wind deflectors


230


. According to this configuration, even if the diffuser


233


is turned in the counterclockwise direction and is opened as shown in

FIG. 3A

, for example, at the heating operation time, an air flow can effectively be directed transversely by the transverse wind deflectors


230


. The directions of the transverse wind deflectors


230


may be changed manually, but it is preferable that the transverse wind deflectors


230


be driven reciproatively in a predetermined angle range by a motor, not shown.




In this example as well, in the air outlet


220


, a first vertical wind deflector


231


and a second vertical wind deflector


232


are provided so as to be turnable. The arrangement sequence is such that when viewed from the exterior panel side, the second vertical wind deflector


232


lies on the front side, and the first vertical wind deflector


231


lies on the rear side.




As in the case of the prior art described before, the first vertical wind deflector


231


may be configured so as to be capable of being turned around a support shaft


231




a


provided almost horizontally in the air outlet


220


.




In the present invention, the second vertical wind deflector


232


is installed in the air outlet


220


via a support frame


300


, and in the air outlet


220


, a recess


250


is provided to store the second vertical wind deflector


232


and the support frame


300


.




The recess


250


is formed by depressing a part of the front side of the air outlet


220


toward the inside of housing, and communicates with the aforementioned air passage.




Specifically, the recess


250


is included in a part of the air outlet


220


, and the blowing area of the air outlet


220


is widened by the recess


250


. This configuration provides a design that visually gives an impression of a high-performance air conditioner in which a large amount of air is blown out through a large air outlet. In this example, an upper end surface


251


of the recess


250


is formed by a part of the drip plate


33


, and an upper end surface


252


thereof is formed by a part of the lower panel


22


.




Referring to

FIGS. 4 and 5

, the support frame


300


is formed of a plate material having almost the same size as that of the second vertical wind deflector


232


. At one end in the transverse direction of the support frame


300


is provided a gear box


310


, and at the other end thereof is provided an end plate


320


.




The gear box


310


and the end plate


320


have a rotating shaft


311


and a rotating shaft


321


, respectively. The rotating shaft


311


and the rotating shaft


321


are arranged coaxially on the side of a rear edge


300

FIG. 5A

, and the other rotating shaft


321


is inserted in a bearing hole


255


formed in the other side plate


253




b


of the recess


250


as shown in FIG.


5


B. Each of the side plates


253




a


and


253




a


may be either the side plate of the lower panel


22


or the side plate of the base plate


1


.




As shown in

FIG. 5A

, the rotating shaft


311


is provided with a protrusion


311




a


at a part of the outer peripheral surface, and a notch


354




a


for causing the protrusion


311




a


to pass through is formed at the edge of the bearing hole


254


. After the rotating shaft


311


has been inserted into the bearing hole


254


, a first spring


361


is fitted on the rotating shaft


311


.




In this example, the first spring


361


consists of a coil spring having two arms


361




a


and


361




b


pulled out of the coil end. As shown in

FIG. 5C

, one arm


361

311




a


, and the other arm


361




b


is fixed to a spring fixing boss


255


projectingly provided on the side wall


253




a.






By this first spring


361


, a front edge


300




a


of the support frame


300


is urged in the counterclockwise direction in

FIG. 5A

(the direction toward the upper end surface


251


of the recess


250


).




As the first spring


361


, an extension spring as shown in

FIG. 6

can be used. In this case, a lever


370


is used. This lever


370


is provided with a cylindrical portion


371


fitting on the rotating shaft


311


at one end thereof, and is provided with a spring fixing hole


372


at the other end thereof, and further is formed with a locking groove


373

on the side surface thereof.




The cylindrical portion


371


is fitted on the rotating shaft


311


while the protrusion


311




a


is engaged with the groove


373


. One arm


361




a


of the first spring


361


is hooked through the hole


372


, and the other arm


361




b


is hooked over the boss


255


. Thereby, the support frame


300


can be urged in the counterclockwise direction as in the above-described example.




Referring to

FIGS. 7A and 7B

, the gear box


310


is made up of a box body


312


in which the side face formed integrally with the support frame


300


is open and a lid body


314


installed detachably to the opening of the box body


312


.




In this example, both of the box body


312


and the lid body


314


have an elliptical shape. The box body


312


is provided with locking claws


313


at one place on the upper side and at two places on the lower side, and the lid body


314


is formed with engagement holes


315


, which are mated with the locking claws


313


, similarly at one place on the upper side and at two places on the lower side.




The gear box


310


houses an input shaft


380


, an intermediate gear


383


, and an output shaft


384


, which constitute driving force transmitting means. The input shaft


380


is rotatably inserted in the rotating shaft


311


, and at one end thereof is formed a rectangular connection hole


381


which is engaged with a driving shaft


410


of a motor


400


shown in FIG.


6


. At the other end of the input shaft


380


is formed with a gear


382


meshing with the intermediate gear


383


. The motor


400


is fixed with screws to the two bosses


256


erected on the side wall


253




a.






The output shaft


384


is of a prismatic shape, and at one end thereof is provided a gear


385


meshing with the intermediate gear


383


. The input shaft


380


, the intermediate gear


383


, and the output shaft


384


are arranged substantially on a straight line, and whereas the input shaft


380


is disposed on the rear edge


300




b


of the support frame


300


, the output shaft


384


is disposed on the front edge


300




b


of the support frame


300


. The output shaft


384


protrudes in parallel with the front edge


300




a


of the support frame


300


from a hole


316


formed in the box body


312


.




In the gear box


310


, bearing bosses


317


for the gears


382


,


383


and


385


are provided. In order for the input shaft


380


and the output shaft


384


to rotate in the same direction, three intermediate gears


383


may be used although one intermediate gear


383


is used in this example. In this case, the bearing bosses


317


have only to be provided additionally at positions indicated by broken lines in the gear box


310


. Also, in place of the intermediate gear, the input shaft


380


and the output shaft


384


can be connected to each other by using a belt (preferably, a timing belt).




Referring again to

FIGS. 4A and 4B

, the relationship between the second vertical wind deflector


232


and the support frame


300


will be explained.




In

FIG. 4A

, when the surface of the second vertical wind deflector


232


facing the support frame


300


is taken as a back surface, and the opposite surface thereof is taken as a top surface, on the back surface of the second vertical wind deflector


232


, a first connecting portion


240


and a second connecting portion


270


are provided at transverse two places on the side of a front edge


232




a


, and between them, for example, two auxiliary connecting portions


260


are provided. These connecting portions


240


,


270


and


260


are arranged on the same axis.




The first connecting portion


240


is connected to the output shaft


384


. As shown in

FIG. 4B

, the first connecting portion


240


includes a cylindrical boss


241


formed transversely in parallel with the front edge


232




a


of the second vertical wind deflector


232


. This cylindrical boss


241


has a rectangular connection groove


242


in which the output shaft


384


is inserted.




Also, a second spring


363


is fitted on the cylindrical boss


241


. In this example, the second spring


363


consists of a coil spring, and has two arms


363




a


and


363




b


pulled out of the coil end.




The second spring


363


is a spring for urging a rear edge


232




b


of the second vertical wind deflector


232


in the counterclockwise direction in

FIG. 4A

(the direction toward the upper end surface


251


of the recess


250


). One arm


363




a


of the second spring


363


is hooked over a hook


243


provided on the second vertical wind deflector


232


, and the other arm


363




b


thereof is hooked through an engagement hole


318


formed in the gear box


310


. By this second spring


363


, a side edge


232




c


of the second vertical wind deflector


232


is brought into contact with the bottom face of the gear box


310


, and the bottom face serves as a stopper for determining the initial position of the second vertical wind deflector


232


.




The second connecting portion


270


also includes a cylindrical boss


271


formed transversely in parallel with the front edge


232




a


of the second vertical wind deflector


232


. This cylindrical boss


271


is inserted in a bearing hole


322


formed in the end plate


320


of the support frame


300


.




Each of the auxiliary connecting portions


260


has a C-shaped catch portion


261


formed by cutting a part of a cylindrical portion. Corresponding to the catch portions


261


, auxiliary bearing holes


301


are formed on the front edge


300




a


of the support frame


300


. The catch portion


261


is rotatably installed to one side on the front edge


300




a


of the auxiliary bearing hole


301


. The number of the auxiliary connecting portions


260


may be selected appropriately according to the length of the second vertical wind deflector


232


.




Next, the operation of the air conditioner in accordance with the present invention will be described. First, at the time of operation stop, as shown in

FIGS. 1A and 1B

, the air outlet


220


is closed by the first vertical wind deflector


231


, the second vertical wind deflector


232


, and the diffuser


233


.




In this case, the support frame


300


is urged by the first spring


361


so as to be housed in the recess


250


, and the second vertical wind deflector


232


is urged toward the support frame


300


by the second spring


363


to close the recess


250


. Since the air outlet


220


is closed in this manner, the whole of the housing is recognized as an integrated design, and the air conditioner is hygienic because dust does not intrude into the housing through the air outlet


220


.




At the cooling operation time, as shown in

FIGS. 2A and 2B

, the first vertical wind deflector


231


and the second vertical wind deflector


232


are turned to a substantially horizontal position. The diffuser


233


may be at the closed position.




The first vertical wind deflector


231


is driven by a special-purpose motor, not shown, and the second vertical wind deflector


232


is driven by rotating the motor


400


in the direction opposite to the urging direction of the first spring


361


, that is, in the counterclockwise direction in FIG.


6


.




At this time, the second vertical wind deflector


232


is brought into contact with the bottom face of the gear box


310


by the second spring


363


, and the output shaft


384


is in a locked state, so that the support frame


300


is opened in the counterclockwise direction together with the second vertical wind deflector


232


.




Thereby, a cold air flow which has been heat-exchanged by the heat exchanger


3


and blown by the air blower


4


is blown out in the substantially horizontal direction through the air outlet


220


.




As a preferred mode of the present invention, as shown in

FIG. 1A

, a longitudinal width D of the second vertical wind deflector


232


is made larger than a longitudinal width E of the first vertical wind deflector


231


, and the recess


250


is utilized as an air passage of the air outlet


220


, by which the cold air flow can be blown to a far distance along the ceiling surface.




In the case where it is desired to direct the cold air flow slightly slantwise downward from the substantially horizontal direction, as indicated by broken lines in

FIGS. 2A and 2B

, the first and second vertical wind deflectors


231


and


232


have only to be further turned in the counterclockwise direction. Also, the diffuser


233


may be turned in the counterclockwise direction and be opened as necessary.




Next, at the heating operation time, as shown in

FIGS. 3A and 3B

, the first and second vertical wind deflectors


231


and


232


are turned so as to be substantially vertical, and the diffuser


233


is opened. To establish this state, the diffuser


233


is turned through a predetermined angle in the counterclockwise direction, and the first vertical wind deflector


231


is turned in the clockwise direction around the support shaft


231




a.






The second vertical wind deflector


232


is turned by driving the motor


400


in the clockwise direction in FIG.


6


. Specifically, the motor


400


is rotated in the direction that is the same as the urging direction of the first spring


361


but opposite to the urging direction of the second spring


363


.




Thereby, the support frame


300


is held on the upper end surface


232


side of the recess


250


by the urging force of the first spring


361


, but the second vertical wind deflector


232


is turned in the clockwise direction against the urging force of the second spring


363


by the output shaft


384


rotating in the clockwise direction, and the rear edge


232




b


thereof is opened.




Thereby, a warm air flow which has been heat-exchanged by the heat exchanger


3


and blown by the air blower


4


is blown out downward toward the floor surface through the air outlet


220


.




In this case as well, by making the longitudinal width D of the second vertical wind deflector


232


larger than the longitudinal width E of the first vertical wind deflector


231


, the warm air flow can be deflected effectively because a distance between the first vertical wind deflector


231


and the second vertical wind deflector


232


becomes large.




In the case where it is desired to blow the warm air flow slightly frontward from the substantially vertical direction at the heating operation time, as indicated by broken lines in

FIGS. 3A and 3B

, the first and second vertical wind deflectors


231


and


232


have only to be further turned in the clockwise direction.




Also, it is preferable that the upper end surface


251


of the recess


250


be formed into an arcuate shape along the turning path of the front edge


232




a


of the second vertical wind deflector


232


.




According to this configuration, a gap between the upper end surface


251


of the recess


250


and the front edge of the second vertical wind deflector


232


can almost be eliminated regardless of the turning angle of the second vertical wind deflector


232


. Therefore, the warm air flow can be deflected effectively without leakage in the horizontal direction.




The above is a detailed description of the preferred embodiment of the present invention. The present invention also embraces an air conditioner having only the second vertical wind deflector


232


as a vertical wind deflector.
