Description

Blow-out opening

The present invention relates to an outlet for controlling blown air used in an air conditioner.

Fig. 23 is a sectional view of the ceiling-type air conditioner described in japanese unexamined patent publication No. 6-70519, showing a conventional air outlet. In fig. 23, reference numeral 1 denotes an air conditioner main body, and the interior of the main body is partitioned by a partition plate 51 into a blowing chamber 52 and a heat exchange chamber 53. The blowing chamber 52 has a fan chamber 54 containing the suction port 2 and a sirocco fan (not shown), and a motor 6 for driving the fan. Inside the heat exchange chamber 53 (the reverse side is not shown), there are the heat exchanger 11 supported by the side plate 55 and a drain pan 90 at the lower part thereof. An outlet 30 having a wind direction deflecting device is formed in the front surface of the main body. The upper portion of the air outlet 30 is composed of a ceiling 56 whose front end is bent in a half-transverse cross shape, a lining 57 closely attached to the inner surface thereof, and an inclined bar portion 58 fixed to the half-transverse cross shape wall surface. A plate-shaped horizontal control plate 40 having a rotation axis is provided at a middle portion in the blow-out port 30, and both ends of the plate 40 are rotatably supported by side plates 55 (opposite sides are not shown), respectively, so as to be vertical and horizontal in the air flow direction. Below the air outlet 30, a fluid guide plate 59 having a circular arc-shaped longitudinal section, which is a curved surface slightly inclined downward toward the downstream, is attached to the side plate 55. A damper 61 is provided on an upstream end of the fluid guide plate 59, and the damper 61 is rotatable about a rotation axis, i.e., a support shaft 60. A bottom plate 62 made of a heat insulating material on which a drain pan 90 is placed is provided at a lower portion of the heat exchanger 11, a curved fluid guide wall 63 inclined downward downstream is provided downstream of the drain pan 90, and the fluid guide wall 63 and the fluid guide plate 59 constitute an auxiliary outlet 50. The air door 61 opens and closes the auxiliary air outlet 50, and when the auxiliary air outlet 50 is closed, the front end of the air door 61 contacts the apex of the fluid guide wall 63. The horizontal control plate 40 operates together with the air gate 61, and when the horizontal control plate 40 is rotated downward, the air gate 61 is opened, and when the horizontal control plate 40 is rotated in the horizontal direction, the air gate 61 is closed.

In the above configuration, when blowing to the horizontal direction, the horizontal control plate 40 basically rotates to the horizontal state. At this time, the air damper 61 rotates together with the horizontal control plate 40 to close the auxiliary air outlet 50, and the air flow located above the horizontal control plate 40 is blown out in the horizontal direction, and the air flow located below the horizontal control plate 40 is separated from the curved surface of the fluid guide plate 59, merged with the air flow above the horizontal control plate 40, and blown out in the horizontal direction.

When the air flow is blown out downward, the horizontal control plate 40 is rotated downward. At this time, the air door 61 rotates together with the horizontal control plate 40 to open the auxiliary air outlet 50. The air flow below the horizontal control plate 40 is deflected downward against the curved surface of the fluid guide plate 59 by the coanda effect, and the air flow above the horizontal control plate 40 is blown out together with the air flow below the horizontal control plate 40. The air flow below the air gate 61 is deflected downward by the fluid guide plate 59, and is deflected downward by the curved surface of the attached fluid guide wall 63 by the coanda effect, and flows through the auxiliary air outlet 50, and then the air flow above the fluid guide plate 59 is ejected and blown downward at a large angle.

The drain pan 90 is formed of expanded styrene, and is pressed by a sheet metal member and fixed to the body.

Since thermal contraction occurs when the refrigerator is not in operation, the drain pan 90 may be deformed.

Since the conventional air outlet is configured as described above, when blowing air horizontally, the air flow below the horizontal control plate is separated from the curved surface of the fluid guide plate, and therefore dew condensation occurs on the fluid guide plate during cooling operation, and dew condensation drops into the room.

The horizontal control plate cannot block the air outlet at any position, and the auxiliary air outlet is usually open from the user's perspective, which deteriorates the appearance of the air conditioner when not in operation.

Further, since the valve and the auxiliary air outlet are provided, steps such as molding and assembling are added in the manufacturing process.

In addition, the conventional drain pan is deformed by thermal contraction under the influence of heat exchange during cooling operation.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a blowout port that can maintain downward and horizontal blowout and that does not cause dew condensation on the vertical wind deflecting plate and the blowout port regardless of the position where the vertical wind deflecting plate is provided.

Another object is to provide a blowout port that is simple in manufacture without using an auxiliary blowout port with a valve or the like in its configuration.

Still another object of the present invention is to improve the design of the outlet which is basically blocked by the vertical wind deflector when the main body apparatus stops operating.

Another object is to provide an air conditioner having the above air outlet.

Still another object is to provide a blow-out port of a wastewater reclamation apparatus that is not deformed by heat.

First embodiment of the invention

Next, a first embodiment of the present invention is explained based on the drawings. Fig. 1 is a perspective view of a ceiling air conditioner body according to the present invention. Fig. 2 is a sectional view thereof. These are indoor units of air conditioners, which are connected to an outdoor unit (not shown) equipped with a compressor, a heat exchanger, an expansion valve, a blower, and the like, and which condition indoor air.

The main body shown in fig. 2 includes a blower 6, a heat exchanger 11, and a control box 10, and when the blower 6 is operated, the indoor air sucked from the suction port 2 passes through the blower 6, the air passage 12 is heated or cooled by the heat exchanger 11, and is supplied from the discharge port 3 into the room. The suction port 2 is provided with a suction grill 7 and a filter 8, so that inflow of indoor dust into the body can be prevented. When the heat exchanger is cooled, dew condensation generated on the heat exchanger is collected by the waste water collecting plate 9 and is discharged to the outside through a drain pipe (not shown).

Fig. 3 shows in detail the configuration of the air outlet of the ceiling air conditioner main body. As shown in fig. 3, the air outlet 3 is formed by an upper wall, a lower wall, and two side walls, and the vertical airflow deflecting plate 4 is pivotally supported by the air outlet 3 by a pivot shaft 17, and the air outlet 3 is provided with the left and right airflow deflecting plates 5 to deflect the blown airflow in an optimum direction.

The control box 10 of fig. 2 performs control of the blower, the vertical wind deflection panel, and the like, mutual control with the outdoor unit, signal transmission/reception control with a remote controller (not shown), and the like.

The outlet portion is described in detail with reference to fig. 4. Fig. 4 is a cross-sectional view of the outlet, showing a state when the vertical wind deflecting plate 4 is stopped. In the present embodiment, the two vertical wind deflector plates 4a and 4b are arranged.

The upper wall of the air outlet is curved as shown by reference numeral 13 in the figure, and a projection as shown by reference numeral 14 in the figure is provided at the front end of the air outlet.

The front surface side of the blow-out port lower wall waste water collecting plate 9 is formed in an arc shape 16, a straight line portion 25 is connected to the arc shape 16, and the front end of the lower wall is formed in an acute angle as shown in fig. 15.

The detailed shape and positional relationship of the upper wall and the lower wall will be described later.

Next, the operation of the vertical wind deflecting plates 4a and 4b will be described. The vertical wind deflecting plates 4a, 4b are rotated about the rotation shafts 17a, 17b in the range from the horizontal blowing position of fig. 5 to the lower blowing position of fig. 6 during rotation, and in the position of fig. 4 during stoppage. The vertical wind deflector during stoppage can substantially block a linear or arc-shaped air outlet from the upper wall protrusion 14 to the lower front end 15. Therefore, when the air conditioner stops operating, the inside of the main body can not be seen from the blow-out port, the main body is complete and beautiful, the design can be improved, the possibility of dust or dirt entering the main body is reduced, and the consideration of dripping the condensed water into the room is not needed. The vertical wind deflecting plates 4a and 4b are rotated by motors mounted on the support members 17a and 17b of the vertical wind deflecting plates 4a and 4 b. In this case, the two vertical wind deflection plates 4a and 4b may be controlled by different motors, or may be controlled by one motor through a link mechanism.

During the rotation, the up-down wind deflecting plates 4a and 4b can be stopped between the positions shown in fig. 5 and 6 by the operation of the remote controller according to the user's intention.

The shape of the upper and lower walls will be described in further detail.

When the up-down wind deflector 4a, 4b is positioned in fig. 5, the top wall protrusion 14 has its tip spaced from the up-down wind deflector 4a by a distance β. The optimum value of β varies depending on the passing wind speed, the amount of air blown, the arrangement of the blower, the heat exchanger, and the like in this portion, and is preferably 5 to 20% of the opening size (x in the drawing) of the air outlet.

Although the pressure loss of the air at the air outlet should be minimized, particularly as shown in fig. 6, when the air is blown downward, a downward vector is generated because the air flows along the vertical wind deflecting plate 4a, and the height α of the projection 14 is preferably 5 to 10% of the size of the opening of the air outlet in order to secure the flow velocity on the vertical wind deflecting plate 4 a.

In order to prevent condensation on the vertical wind deflection plate 4a, the width of the protrusion 14 can be appropriately increased or decreased within a range where condensation does not occur, based on the same width as that of the vertical wind deflection plate 4 a. Alternatively, as shown in FIG. 3, the distance from the outlet end may be 3.0 to 20 mm. By providing the space, since the air velocity at the wall edge of the air outlet is low and the room air is easily entrained, the air velocity is increased, and the air flow blown out flows along the wall surface, and dew condensation can be prevented.

As shown in fig. 6, when the wind is blown downward, the protrusion 14 should be positioned forward of the front end 18a of the upper vertical wind deflection plate 4a and rearward of the front end 19a on the opposite side.

The shape up to the protrusion 14 is formed by an S-shaped, circular arc-shaped curved surface or a straight line in which the flow path gradually narrows downward as shown in fig. 6.

The lower wall front end 15 is disposed rearward (on the main body side) of the front end 19b of the vertical wind deflecting plate 4b on the lower wall side in fig. 6.

The lower wall front end 15 is located rearward (body side) of the upper wall projection 14. The line connecting the protrusion 14 and the front end 15 of the lower wall (angle ψ in fig. 4) has an angle of 10 to 90 degrees with respect to the vertical direction.

The shape of the lower wall, if a straight portion 25 in fig. 6 is provided, the portion 16 in the figure may be a straight line or a curved line. And a single face may be used when the drainage recovery plate is unnecessary.

Next, the airflow around the outlet will be described.

First, the horizontal blowing is explained based on fig. 7.

The air flow at the upper portion of the air outlet flows along the curved portion 13 in the figure, and flows downward while meeting the protrusion 14 in the figure, and flows along the upper side surface of the vertical wind deflection plate 4 a. Since the air passage has a shape like the curved portion 13, no vortex is formed in this portion, and the pressure loss of the air flow blown out does not increase. Since the flow of the up-down wind direction deflecting plate 4a in the horizontal direction of the up-down wind direction deflecting plate 4a is formed by the protrusion, the inflow of the indoor air (secondary air) into the air passage can be prevented. Thus, the secondary air is mixed with the blown air flow, and condensation does not occur in the passage during the cooling operation.

Since the airflow flows along the vertical wind direction deflection plate 4a, the cold air during cooling can be sent to the upper part of the room as long as the vertical wind direction deflection plate 4a is kept horizontal, and the cold air does not contact with the user to lower the room temperature. Therefore, the comfort is greatly improved.

The airflow at the lower portion of the air outlet flows along the curved surface 16 in the figure and the straight portion 25 in the figure, and enters the room from the front end 15 (shown by arrow 20 in the figure). At this time, as shown in fig. 8(a), the outlet front end 15 reliably separates the indoor air and the outlet airflow. However, when the shape is a curved surface as shown in fig. 8(b), the blown air flow forms a vortex flow 20b and mixes with the indoor air 21b, and dew is formed in the curved surface portion or the air passage during cooling.

In view of the above effects, the vertical shape of the air outlet prevents condensation during cooling, eliminates the need for a water absorbing material, and significantly reduces the manufacturing cost.

Next, the air flow when blowing downward is explained with reference to fig. 9.

In fig. 9(a), the airflow passing above the air outlet is deflected downward by the projection at the front end of the air outlet, and flows along the upper surface of the vertical wind deflection plate 4a (fig. 22 a). In this case, the above-described operation and effect are more remarkable when the protrusion 14 and the tip end portion of the vertical wind deflector 4a are partially overlapped as shown in the drawing. However, if the projection is not provided, the airflow passing over the upper side of the vertical wind direction deflecting plate 4a directly enters the room as shown in fig. 9 b. Therefore, the downward flow component is reduced, and particularly, the problem that the generated air flow cannot reach the ground surface in heating is solved. During cooling, the indoor air flows onto the upper surface (23 b in the figure) of the up-down wind deflector 4a, and a temperature difference occurs between both surfaces of the up-down wind deflector 4a, which is a cause of dew condensation.

The present invention can solve the above two problems by causing the airflow to flow on both surfaces of the up-down wind deflector 4a by the action of the protrusions in the drawing.

By providing the line connecting the positions of the projection 14 of the outlet upper portion and the outlet lower portion front end 15 with an angle (ψ in fig. 4) in the range of 10 to 90 with respect to the vertical direction, it is possible to flow in the downward direction, and in particular, it is possible to deliver hot air to the user's feet during heating. Since the front end of the upper wall is located on the downstream side of the air flow with respect to the front end of the lower wall, the pressure loss at the time of downward blowing is small, the air volume can be ensured, and the noise is low.

When the air is blown downward, as shown in fig. 6, the projection 14 of the upper wall is positioned forward of the upper vertical wind deflection plate front end 18a, and the front end of the lower wall is positioned rearward of the lower vertical wind deflection plate front end 19b, so that the downward airflow can be easily formed, and the downward airflow can be reliably ensured.

The same effects as described above can be obtained even if the upper wall is formed only by the upper wall tip portion without providing the projection 14.

When the vertical wind deflecting plate is a single piece as in the second embodiment of the present invention described later, the same operation and effect as described above can be obtained if the upper and lower tip portions of the vertical wind deflecting plate have the above-described relationship.

In the first embodiment, an example in which the air outlet of the present invention is applied to a ceiling-type air conditioner has been described, but the air outlet of the present invention is not limited to the use in a ceiling-type air conditioner, and can be widely used for air outlets in air conditioners and air cleaners, humidifiers, ventilators, food stoves, air conditioning fans, freezing/cooling cases, showcases, gas/oil hot blast stoves, and green heaters, for example, for wall-mounted type, window type, cabinet type, ceiling-embedded type, and central air conditioners (duct-type air conditioning and blow-out type).

The outlets described in embodiments 2 to 6 of the present invention described later can also be widely used as described above.

Example 2

Fig. 10 is a sectional view showing the outlet port at the time of operation stop. As shown in fig. 10, the vertical wind deflecting plate 4 is hereinafter described as being formed of one plate.

The same basic configuration, operation, and effects as those of embodiment 1 of the present invention will not be described, and only the differences will be described.

The height (α in the drawing) of the upper wall front end portion projection 14 is preferably in the range of 10 to 40% of the opening size (x in the drawing) of the air outlet. Compared with the case where the vertical wind deflection plate 4 described in embodiment 1 of the present invention is two, the height of the protrusion 14 is increased because the distance between the upper wall and the upper surface of the vertical wind deflection plate 4 is large when one vertical wind deflection plate is used.

As shown in fig. 11, in order to position the front end 18 of the vertical wind deflection plate 4 above the front end of the projection 14 at the time of downward blowing, the angle of the vertical wind deflection plate 4 and the size of the projection 14 must be set. With this configuration, the flow of the air current along the upper surface of the vertical wind deflection plate 4 can be reliably ensured.

The upper wall curved portion 13 has an S-shape with a radius of curvature r1, r 2. The size of the curved portion is preferably r1 > r 2. r1 hours, the air flow in the flow path is turbulent, the pressure loss is increased, and the air volume is reduced. r2 hours by making the protrusion upright, the airflow forms a downward component. In this embodiment, the ratio of r1 and r2 is 4 to 1. At this time, it is necessary to set r1 > r 2.

The effect of the horizontal blowing is the same as that of embodiment 1.

When the air outlet is closed by the vertical wind deflecting plate 4 during the operation stop (dotted line in the figure) in the case of the downward blowing and the upper wall having the shape shown in fig. 13, the vertical wind deflecting plate 4 is increased in size to increase the driving torque. As described in embodiment 1 of the present invention, in the case of downward wind blowing as shown in fig. 13, the upper wall front end portion is located forward of the upper front end of the up-down wind deflecting plate, and the lower wall front end portion is disposed rearward of the lower front end of the up-down wind deflecting plate, so that the downward flow rate can be easily configured reliably, and particularly, as shown in fig. 13, when the up-down wind deflecting plate is one, the up-down wind deflecting plate is large, so that the airflow 22 blown out during downward blowing is separated from the up-down wind deflecting plate 4 as shown in fig. 13, and the airflow volume of the downward airflow is reduced, and particularly, during heating, the airflow cannot reach the floor surface. Since the indoor air contacts the upper surface of the up-down airflow direction deflecting plate 4 during cooling, a temperature difference is formed between both surfaces of the up-down airflow direction deflecting plate 4, which is a cause of dew condensation.

In order to solve these problems, the blown air flow must be surely formed to flow along the front surface of the up-down wind deflector 4, and particularly when the up-down wind deflector 4 is one, the flow rate passing through the upper surface of the up-down wind deflector 4 must be increased because the up-down wind deflector 4 is large. When the flow rate is small, the airflow may be separated from the vertical wind deflector 4 on the way of the vertical wind deflector 4.

In this embodiment, as shown in fig. 12, the upper wall is formed in an S-shape, and the distance between the vertical wind deflection plate 4 and the upper wall is increased, so that the amount of air passing over the upper surface of the vertical wind deflection plate 4 can be increased, and downward airflow and airflow flowing along the vertical wind deflection plate 4 can be formed by the front end projection 14.

Therefore, even if the vertical wind deflection plate 4 is one, the downward air volume can be ensured, and particularly, in the heating, the airflow can reach the floor in the room, thereby greatly improving the quickness. Further, the pressure loss at the time of blowing down can be reduced by the mutual arrangement relationship of the upper wall, the lower wall, and the vertical wind deflecting plate 4, and the noise can be reduced while securing the air volume.

Since the vertical wind deflecting plate 4 can be set at any angle from horizontal blowing to downward blowing, condensation does not occur in the vertical wind deflecting plate 4 and the air passage, and therefore, a water absorbing material is not required, and the manufacturing cost can be greatly reduced.

Further, in order to substantially block the outlet when the operation is stopped, the vertical wind deflection plate 4 can be made small by providing the projection 14 slightly larger than that of embodiment 1 on the upper wall, and horizontal blowing or downward blowing can be realized by the shapes of the upper wall and the lower wall, thereby improving the design at the time of stopping in addition to ensuring the original function.

Example 3

In this embodiment, an embodiment in which the airflow is sent downward more than in embodiments 1 and 2 and condensation does not occur during cooling will be described.

As shown in fig. 14, the angle (θ in the drawing) 15 of the straight portion of the lower wall on the downstream side of the wind with respect to the horizontal is preferably set to 7 to 20 °, and a circular arc-shaped wiring line denoted by reference numeral 16 in the drawing is designed to be connected thereto. A plastic or metal thin plate (hereinafter referred to as a current plate) 24 is provided at a position of about 5-10mm from the arc. The thickness of the sheet must be the minimum thickness that does not deform while reducing the pressure loss of the blown air volume. The dimension γ in the figure differs depending on the size of the air outlet provided, and is 15mm in the present embodiment. The longitudinal width desirably coincides with the longitudinal width of the air outlet. In addition, the inclination of the rectifying plate 24 is preferably 0 to 10 ° with respect to the lower wall straight portion 25.

As shown in fig. 14, the vertical wind deflecting plates 4a and 4b substantially block the outlet front surface when the operation is stopped.

As shown in fig. 15, when blowing down, the vertical wind deflecting plates 4a and 4b are rotated at the illustrated positions. At this time, since the straight portion is inclined in the downstream direction as compared with the above embodiment, the distance δ is increased, the pressure loss at this portion is reduced, and the airflow flows downward along the vertical wind deflecting plate 4b and the inclined lower wall (fig. 16 a).

At this time, the airflow reliably flows along the lower wall by the rectifying plate parallel to the straight portion inclined in the downstream direction.

However, if no rectifying plate is provided, as shown in fig. 16(b), the airflow is separated from the lower wall surface and directly enters the room, and the airflow deflected by the up-down wind direction deflecting plate 4b is pushed back to the horizontal direction.

Thus, by inclining the shape 25 of the lower wall and providing the rectifying plate, the airflow can be sent in a direction further downward than the above-described embodiment. In this embodiment, the blowing angle at the straight portion horizontal plane is increased from 65 ° downward from the horizontal (embodiments 1, 2) to 70 °.

Since the air outlet of the present embodiment is applied to an air conditioner, even if the air outlet is installed at a high position in a room, air can be sent to the lower part of the foot, and a quick space for head cooling and foot heating is formed particularly at the time of heating.

In the horizontal blowing, the airflow near the lower wall spreads as shown in fig. 17, and the airflow blown out by the rectifying plate also flows along the lower wall, so that dew condensation does not occur during manufacturing.

The lower wall straight portion is inclined at about 15 ° with respect to the horizontal, and if the angle is too large, unwanted secondary air is liable to enter when blown out horizontally.

In the present embodiment, the case where the vertical wind deflection plate 4 is two is described, but the same effect can be obtained when the vertical wind deflection plate 4 is one.

Example 4

This embodiment shows an example of making the airflow more downward.

As shown in fig. 10, if the outlet is substantially closed when the operation is stopped, the vertical wind deflecting plate 4 rotates and the front end 19 thereof is positioned above the horizontal straight portion 25 of the lower wall when the downward blowing in fig. 12 is performed.

The airflow flows along the straight line portion as shown by the arrow in the figure, and is blocked by the up-down wind deflector 4 to flow downward along the up-down wind deflector 4.

As shown in fig. 18, the protrusion 26 is provided on the lower wall straight portion, and the airflow near the lower wall rises once upward, and then is blocked again by the up-down wind deflector 4 to flow downward, and the airflow is not blocked any more, and flows at a large downward deflection angle. The front end of the projection 26 should be higher than or equal to the front end 19 of the up-down wind deflector 4. In this embodiment, the air blowing angle from 65 ° to 70 ° with respect to the horizontal in the above embodiments 1 and 2 is increased.

Therefore, if the downward deflection angle can be changed greatly, even if the main body is arranged at a high position, the wind can be sent to the ground, and the adaptability can be improved particularly in heating.

This embodiment is basically the same as the above-described embodiments, and does not deteriorate the design at the time of stop, and does not cause dew condensation and does not require a water absorbing material regardless of the setting of the vertical wind deflection plate 4 at the time of cooling.

Example 5

The shape of the left and right ends of the air outlet will be described. Fig. 19 shows a perspective view of the left end of the air outlet of the present embodiment. The right and left wind direction plates 5 are omitted. The upper and lower walls have projections, and the upper and lower wind deflecting plates 4 are rotatably supported by a rotating shaft 17.

Fig. 20 shows a cross-sectional view a-a of fig. 19. In the left end shape, the outer side 41 is a small arc, and the outlet side 42 is a large arc, and the connection portion is in an edge shape. The outlet port 42 may be a straight line, and the outer side may not be a shape that enlarges the air passage. In this case, the vertical wind deflector 4 and the left end of the protrusion of the upper and lower walls are preferably spaced from the left end wall by about 0 to 20 mm. This is also true for the current plate.

The gas flow is explained below. The right and left wind deflecting plates 5 are inclined in the direction opposite to the wall on the downstream side of the wind. The air stream flows along the left wall diffusing edge. The blow-out airflow flows along the walls in the vicinity of the walls due to the coanda effect and flows directly into the indoor space from the edges. At this time, the indoor air also flows along the outside of the left wall, and the flow velocity of the blown air flow is high, and the air flows directly forward from the edge without mixing with the indoor air. Whereas if the wall 42 on the side of the outlet port is in the shape of a small circular arc, the outlet air is separated from the wall and mixed with the indoor air because of the high speed. The shape of the outer wall 41 may be a curved surface having any size as long as the indoor air having a low flow rate is not separated, but in consideration of design, a small circular arc shape is formed in many cases.

As an application example of the present embodiment, the same effect can be obtained by providing the projection 43 on the foremost end as shown in fig. 21. The protrusions 43 may be integrally formed or may be separately formed and then bonded together.

If the upper and lower wind deflection plates 4, the left ends of the protrusions 43 of the upper and lower walls are spaced apart from the left end wall, the wind flowing through the ends increases and the mixing of the air flow and the indoor air is further prevented.

The right wall is also symmetrical in shape as in fig. 20 and 21.

As described above, since the amount of air blown out from the left and right ends is increased and the shape of the wall prevents the mixing flow of the blown-out airflow and the indoor air, condensation at the air outlet end during cooling and dehumidification can be prevented, and a water absorbing material is not required, thereby reducing the manufacturing cost.

Example 6

Fig. 22 is a sectional view of a blowing port according to a sixth embodiment of the present invention.

In fig. 22, reference numeral 46 denotes a styrene foam drain recovery device, and constitutes a blow-out port lower wall. The drain recovery device 46 is formed by integrally inserting the left and right windage deflector holding and fixing plates 45, and the left and right windage deflector holders 44 are fixed to the left and right windage deflector holding and fixing plates 45 by bolts or hooks.

In the configuration of the drain recovery device of the present embodiment, the left and right wind direction deflection plate holding fixing plates 45 functioning as the reinforcing members are embedded in the entire length in the longitudinal direction of the drain recovery device, and therefore, the drain recovery device that is thermally contracted during the cooling operation is not deformed and can be held substantially in its original state because the reinforcing members are embedded therein.

As described above, in the first air outlet of the present invention, when the air is blown out horizontally, the air flow in the upper portion of the air outlet flows along the upper wall, the air flow flows toward the vertical air deflecting plate under the influence of the protrusion at the front end of the upper wall, flows along the horizontal vertical air deflecting plate, and does not mix with the air outside the air outlet, while the air flow in the lower portion of the air outlet directly enters along the straight portion of the lower wall.

When blowing down, the blown air flow is deflected downward by the upper wall protrusion and flows along the vertical wind direction deflection plate without separating, so that a downward air flow is obtained, and when blowing out cold air, dew condensation on the vertical wind direction deflection plate can be prevented. Further, since the lower wall front end portion is located on the wind upstream side of the upper wall projection portion, the downward airflow is smoothly formed, and the downward airflow can be reliably obtained.

In the second air outlet of the present invention, since the lower wall straight portion is inclined downward on the downstream side and the rectifying plate is provided near the lower wall, the air flow rectified by the rectifying plate has a downward component during downward blowing, flows along the lower wall inclined straight portion, and does not interfere with the downward flow caused by the vertical wind deflecting plate, and merges with each other, so that the air flow can be deflected downward more than the air outlet of the first invention and the air outlet can directly blow the downward air flow.

In the third air outlet of the present invention, the downward airflow similar to the above-described second invention can be obtained by once directing the airflow near the lower wall upward within the control range of the vertical airflow deflecting plate by the protrusion provided on the horizontal linear portion of the lower wall, and then directing the downward airflow downward and merging the downward airflow by the vertical airflow deflecting plate without affecting the flow of the airflow from above.

According to the above method, air can be blown vertically downward from the air outlet without increasing the number of components.

In addition to the above-described effects of the invention, the fourth air outlet of the present invention is configured such that, when the airflow is blown out downward by the vertical wind deflecting plate, the tip end portion of the vertical wind deflecting plate closest to the upper wall is located on the upstream side of the projection of the upper wall, and the tip end portion of the vertical wind deflecting plate closest to the lower wall is located on the downstream side of the tip end portion of the lower wall, whereby the downward flow is facilitated and the downward airflow can be further ensured.

The fifth air outlet of the present invention has the effects of the above-described inventions, and in addition, since the air outlet is substantially closed when the operation is stopped, dust or dirt cannot enter the main body when the operation is stopped, and the design can be improved without impairing the performance of the apparatus.

In the sixth aspect of the present invention, since any one of the air outlets of the first to fifth aspects of the present invention is mounted on an air conditioner, condensation on each part of the air outlet can be prevented during cooling, and a sufficient downward airflow can be obtained during heating, and the airflow can be made to reach the foot root of the user, thereby obtaining a quick and comfortable space with a cool head and a hot foot.

The air outlet of the seventh aspect of the invention has an upper wall, a lower wall, and a vertical wind direction deflecting plate provided between the upper wall and the lower wall and capable of changing the airflow from the horizontal direction to the downward direction, and when the front end portion of the upper wall is located on the downstream side of the front end portion of the lower wall and the airflow is blown downward by the vertical wind direction deflecting plate, the front end portion of the vertical wind direction deflecting plate closest to the upper wall is located on the upstream side of the front end portion of the upper wall, and the front end portion of the vertical wind direction deflecting plate closest to the lower wall is located on the downstream side of the front end portion of the lower wall, so that the downward flow is easily formed, and the downward airflow is. Further, the structure can reduce the duct resistance in the blowing direction when blowing downward, and thus can avoid the reduction of the air volume and the blowing noise when blowing downward.

In the air outlet according to the eighth aspect of the invention, in addition to the seventh aspect of the invention, since the protrusion is provided at the front end of the upper wall, in the horizontal air outlet, the air flow flowing along the upper wall in the air flow at the upper portion of the air outlet is directed toward the vertical air deflection plate by the protrusion at the front end of the upper wall, flows along the horizontal vertical air deflection plate, and does not mix with the air outside the air outlet, and the horizontal air flow is reliably obtained.

In the downward blowing, the blown air flow is deflected downward by the protrusion of the upper wall and flows along the vertical wind deflection plate without being separated, so that the downward air flow is obtained, and the condensation of the vertical wind deflection plate can be prevented when the cold air is blown.

In the air outlet of the ninth aspect of the invention, in addition to the effects of the above aspects of the invention, since the upper wall has the linear portion that is horizontal and the tip end portion that is acute-angled, the air flow at the lower portion of the air outlet during horizontal blowing directly flows in along the linear portion of the lower wall, and the air flow that is blown out from the air outlet is reliably separated from the air outside the air outlet by the acute-angled portion at the end portion of the lower wall, so that the air flow in the horizontal direction is reliably obtained, and at the same time, when cold air is blown out from the air outlet, the lower portion of the air outlet is mixed with the air outside the air outlet, so that condensation does not occur.

In the tenth aspect of the invention, the air conditioner having the air outlet according to any one of the seventh to ninth aspects of the invention can prevent condensation on each part of the air outlet during cooling, and therefore does not require a water absorbing material.

In the eleventh aspect of the invention, in addition to the tenth aspect of the invention, the front surfaces of the left and right ends of the air outlet are formed in two circular arcs, the air outlet side is in a large circular arc shape or a straight line shape, the outer side of the main body is in a small circular arc shape, and the connecting portion thereof is in an edge shape, so that the blown air flows directly forward from the edge portion without separating from the wall, and does not flow in a mixed manner with the indoor air at the left and right ends of the air outlet, and therefore, during cooling, condensation at the left and right ends of the air outlet can be prevented, and a water absorbing material is.

In the twelfth aspect of the invention, the lower wall of the air outlet is formed by the drain recovery device of synthetic resin embedded in the reinforcing member also serving as the component mounting base, so that thermal deformation of the drain pan can be prevented to improve reliability, and since the reinforcing member also serves as the component mounting base, for example, mounting of the left and right inward deflection plates and the like becomes easy.
