Claims
- 1. An air conditioner which comprises, in combination: an air intake structure; a blower means positioned in said air conditioner for drawing air into said air conditioner through said air intake structure; a heat exchanger in the path of the air drawn into the air conditioner by said blower means; and an air exit structure in the path of the air being blown by said blower means and comprising a plate-like sheet of rigid material having an aperture therein forming a nozzle for issuing a main stream of air as the air passes therethrough, said sheet of material having a relatively small dimension in the direction of the thickness thereof as compared with the width of the nozzle in the direction at right angles to the direction of flow of the air therethrough, the edges of said sheet of material around said nozzle having a shape for causing the air from upstream of said nozzle to flow therethrough in a main stream which is substantially unconstricted and having low inertia so that the direction of flow can be diverted easily,
- control chamber means positioned downstream of said nozzle and in spaced relation to said nozzle for developing a pressure differential in the main stream of air flowing from said nozzle,
- a pair of spaced opposed walls at a position downstream of said control chamber means and having a shape diverging away from each other in a direction downstream with respect to the direction of flow of the main stream of air and opening outwardly in a direction away from said nozzle, said walls being spaced from each other at the upstream side a distance slightly greater than the width of the nozzle for providing a space for the main stream of air passing through the nozzle to be deflected,
- said control chamber means having respective openings opening into the path of the main stream of air between said nozzle and said walls and having respective control apertures opening into said chamber means and having a cross-sectional area of a size sufficient for compensating for the reduction in pressure within the corresponding control chamber means due to the air within such control chamber means having been drawn into the main stream of air as the main stream of air flows past the openings opening into the path of the main stream, and
- interceptor means associated with said control apertures for controlling the amount of the cross-sectional area of each of said control apertures which is open, said nozzle being so positioned relative to said walls that the direction of flow of the main stream of air can be selected to be in any direction within the space between the walls by the effect of said pressure differential.
- 2. An air conditioner as claimed in claim 1, wherein said interceptor means is adjustable for adjusting the degree of closure of the control apertures.
- 3. An air conditioner as claimed in claim 1, further comprising drive means connected to said interceptor means for continuously operating said interceptor means for adjustably closing any of said control apertures at least substantially completely.
- 4. An air conditioner as claimed in claim 3, wherein said drive means comprises a wind impeller driven in one direction by the flow of a portion of the air supplied by said blower menas.
- 5. An air conditioner as claimed in claim 3, wherein said drive means comprises a wind impeller driven in one direction by the flow of a portion of the air supplied by said blower means, and further comprises a switching means for stopping rotation of said wind impeller when said closure means is at the desired position to adjust the degree of closure of the control apertures.
- 6. An air conditioner as claimed in claim 3, wherein said drive means comprises an electrically operated motor.
- 7. An air conditioner as claimed in claim 1, wherein said interceptor means comprises a rotary member adjacent said control apertures and having a first aperture alignable with said control apertures by rotation of said rotary member for controlling the opening of the control apertures, said rotary member having a second aperture spaced from said first aperture and having a smaller size than said first aperture and alignable with said control apertures by rotation of said rotary member, said second aperture being aligned with said control aperture when communication between said first aperture and said control aperture is interrupted, and a diaphragm unit positioned adjacent and in spaced relation to said second aperture and movable towards said rotary member for closing said second aperture in response to a fluidic dynamic pressure detected at a position adjacent one of said walls.
- 8. An air conditioner as claimed in claim 1, further comprising a rectifier positioned upstream of said nozzle.
- 9. An air conditioner as claimed in claim 1, wherein said air exit structure is so positioned as to receive the air which has been uniformly distributed towards said air exit structure from the air blower means.
- 10. An air conditioner, which comprises, in combination:
- a housing structure for the air conditioner having an air suction opening and an air exit structure of substantially rectangular shape;
- a heat exchanger housed within said housing structure; and
- an air blower means housed within said housing structure for drawing air into said housing and over said heat exchanger and directing it towards the air exit structure and then towards the outside of said housing structure, said air exit structure comprising a plate-like sheet of rigid material having an aperture therein forming a nozzle for issuing a main stream of air as the air passes therethrough, said sheet of material having a relatively small dimension in the direction of the thickness thereof as compared with the width of the nozzle in the direction at right angles to the direction of flow of the air therethrough, the edges of said sheet of material around said nozzle having a shape for causing the air from upsteam of said nozzle to flow therethrough in a main stream which is substantially unconstricted and having a low inertia so that the direction of flow can be diverted easily,
- control chamber means positioned downstream of said nozzle and in spaced relation to said nozzle for developing a pressure differential in the main stream of air flowing from said nozzle,
- a pair of spaced opposed walls at a position downstream of said control chamber means and having a shape diverging away from each other in a direction downstream with respect to the direction of flow of the main stream of air and opening outwardly in a direction away from said nozzle, said walls being spaced from each other at the upstream side a distance slightly greater than the width of the nozzle for providing a space for the main stream of air passing through the nozzle to be deflected, said nozzle being so positioned relative to said walls that the direction of flow of the main stream of air can be selected to be in any direction within the space between the walls by the effect of said pressure differential,
- said control chamber means having respective openings opening into the path of the main stream of air between said nozzle and said walls and having respective control apertures opening into said chamber means and having a cross-sectional area of a size sufficient for compensating for the reduction in pressure within the corresponding control chamber means due to the air within such control chamber means having been drawn into the main stream of air as the main stream of air flows past the openings opening into the path of the main stream,
- closure means operatively associated with said control apertures for adjustably closing and opening the control apertures alternately thereby adjusting the amount of the cross-sectional area of each of said control apertures which is open, to control the pressure within the corresponding control chamber means,
- a wind impeller driven in one direction by the flow of a portion of the air supplied by the air blower means and connected to said closure means for driving said closure means,
- means for stopping rotation of said wind impeller at any desired position to interrupt the supply of a drive from the wind impeller to said closure means, and
- a rectifier positioned upstream of said nozzle for rectifying the air supplied from the air blower means.
