Description

Decorative panel of air conditioner, air outlet part, and air conditioner

technical field

The present invention relates to a decorative panel, an air outlet portion of an air conditioner, and an air conditioner, and more particularly to a structure of a horizontal vane provided at an air outlet for adjusting the blowing direction of conditioned air.

Background technique

Conventionally, for example, air outlets of ceiling-embedded air conditioners and intermittent air conditioners are provided with horizontal vanes that can change the blowing direction of conditioned air up and down. In addition, the blowing direction of the conditioned air is made relatively downward during the heating operation by using the horizontal blades, and relatively upward during the cooling operation so as to form a state close to parallel to the ceiling surface (so-called horizontal blowing). In this way, the temperature distribution in the room can be uniformed in each operation state, and the air-conditioning efficiency can be improved.

However, in the above-mentioned horizontal blowing state, fine particle-like dust contained in the blown air-conditioned air adheres to the ceiling surface, and the ceiling surface is often partially polluted. Specifically, when the air conditioner is viewed from the horizontal direction as shown in FIG. 10 , the airflow blown out from the air blowout port a in a horizontal blowout state is substantially V-shaped when viewed along the flow. Here, in the central portion in the longitudinal direction of the air outlet a, the negative pressure becomes stronger because the blowing velocity of the air is fast, and the air does not adhere to the ceiling surface b near the outlet because of the fast and strong airflow.

On the other hand, since the air blown out from the end of the air outlet a is slow, the negative pressure in the center is drawn and adheres to the ceiling surface b near the outlet a. And at this time, the dust in the slow airflow blown from the end of the air outlet a (including the dust contained in the slow airflow blown from the end of the air outlet a and the dust entrained in the room by the slow airflow) adheres. on the ceiling surface b. Therefore, the contamination of the ceiling is largely distributed in the region D ( See Figure 2).

In order to avoid such pollution, Japanese Patent Application Laid-Open No. 3-160266 proposes to detachably set auxiliary fins on the horizontal blades so that the blowing direction is shifted to the ceiling surface side, and according to the ease of ceiling pollution To assemble and disassemble the technical scheme of the auxiliary fin. In the air conditioner described in this publication, for example, in an environment where there is a lot of dust in the indoor air and ceiling pollution is likely to occur, or in a place such as a hospital where the requirements for pollution prevention are particularly high, the auxiliary fins are removed, and the horizontal blades are replaced. It is adjusted to be downward, and auxiliary fins are installed in the environment where ceiling pollution is difficult to occur and where the requirements for pollution prevention are low, and it is adjusted to blow out horizontally.

However, even if the auxiliary fins are installed as in the above conventional example, the auxiliary fins have to be removed in an environment where the ceiling is prone to pollution, etc. As a result, the conditioned air from the air outlet is always blown downward , In the cooling operation where the horizontal blowing should be performed, not only the reduction of the air conditioning efficiency is caused, but also the problem of a sense of imbalance (so-called ventilation) caused by the cold wind directly blowing to the people in the room.

The present invention was made in view of such a problem, and its purpose is to set the appropriate blowing direction according to the operating state of the air conditioner by improving the shape of the horizontal vane provided at the air blowing port, and to prevent the ceiling from blowing out. surface contamination.

disclosure of invention

The present invention improves the shape of the horizontal blades so that the blowing direction of the conditioned air from the both sides in the longitudinal direction of the air blowing port is lower than that in the central part in the longitudinal direction.

Specifically, the solution adopted by the present invention is based on the following content: there is an air outlet 16 for air-conditioned air blown out from the ceiling surface to the indoor space, and a horizontal air outlet 16 for adjusting the blowing direction of the air-conditioned air is provided on the air outlet 16 . The decorative panel and the air outlet part of the air conditioner of the blade 18, the air conditioner that the above-mentioned decorative panel 14 is installed along the ceiling surface, the air conditioner that the above-mentioned air outlet part 51 is installed on the ceiling surface and connected with the air conditioner body 53 through the air supply duct 52 .

In addition, the horizontal blade 18 has openings 18 c through which conditioned air passes, at airflow upstream side edge portions at both ends in the longitudinal direction.

In this configuration, the openings 18c can be formed by notches formed at the airflow upstream side edge portions of both ends in the longitudinal direction of the horizontal blade 18 .

Also, by twisting the above-mentioned horizontal vane 18 from the central part in the longitudinal direction to both ends so that the edge part on the upstream side of the airflow gradually rises to form a three-dimensional shape, the two ends of the horizontal vane 18 can also be provided with the above-mentioned opening. 18c equivalent part.

In addition, by forming at both ends of the central portion of the horizontal blade 18 in the longitudinal direction, an air flow upstream side edge portion that allows more air flow to flow through the negative pressure surface side of the horizontal blade 18, it is also possible to provide the above-mentioned opening 18c. quite a portion.

With the above-mentioned structure, when air-conditioned air is blown into the room from the air outlet 16, in the cooling operation, the air-conditioned air is guided to a direction approximately close to the horizontal at the central part of the air outlet 16 at which the blowing flow rate is relatively fast. At both ends in the longitudinal direction of the slow air outlet 16 , a part of the conditioned air passes through the openings 18c and the like at both ends of the horizontal blade 18 and is blown downward in the central portion. Thereby, because the air flow that flows through the negative pressure surface side of this horizontal vane 18 at both ends of the horizontal vane 18 increases, so at both ends of the air outlet 16, the conditioned air with a slow initial velocity is blown out and flows along the ceiling surface. Less traffic. In addition, during the heating operation, by adjusting the horizontal blade 18 downward, the air-conditioned air is blown downward from the entire air outlet 16 into the room.

Also, in the above-mentioned structure, the horizontal blade 18 is made into a shape curved toward one side wall surface in the short side direction of the air blowing port 16 (shape protruding downward) as the upstream side of the blown airflow becomes the downstream side. ), and it is preferable to form the aforementioned side wall surface of the air outlet 16 into a shape curved in the same direction as the horizontal vane 18 . In addition, the wall surface on one side is not necessarily limited to a curved shape, but may be formed in a shape along the horizontal blade 18 . In addition, the other side wall surface may be formed into a shape that is more gently curved than the one side wall surface, or may be formed into a straight shape.

With such a structure, as the horizontal blade 18 forms a state in which the air flow on the negative pressure surface side of the horizontal blade (the downward air flow on the back side (air flow upstream side end edge)) flows on the both ends thereof increases, Blowing is reliably performed at the central portion of the horizontal blade 18, and air is reliably blown downward at both end portions.

Also, in the air conditioner of the present invention, when the air outlet 16 has an enlarged portion 16L (see FIG. 9 ) in which the length of the opening in the longitudinal direction is enlarged at the portion facing the indoor space, the opening 18c of the horizontal vane 18 can be formed in the air conditioner. A region corresponding to the enlarged portion 16L of the air outlet 16 . In this case, when the airflow upstream side edge portion gradually rises from the longitudinal center side of the horizontal blade 18 to both ends, and the airflow flowing through the negative pressure surface side of the horizontal blade 18 is increased, the horizontal blade is formed. The same applies to the edge portion on the airflow upstream side of 18 , and these portions may be formed in regions corresponding to the enlarged portion 16L of the air outlet 16 .

In this way, when the air outlet 16 has the enlarged portion 16L, when the opening 18c or a structure corresponding thereto is not provided, the blown air tends to stay at both ends of the horizontal blade 18, and when the gap, etc. When the opening 18c of the opening 18c is formed with a length corresponding to the enlarged portion 16L of the air blowing port 16, since the airflow flowing along the horizontal blade 18 becomes downward at both ends of the length direction, the airflow stagnant in the horizontal blade 18 can be reduced. Air volume on the inner side.

The effect of the invention

With the solution described above, during the cooling operation in which air-conditioning air is required to be blown out horizontally, since the air is blown out in the horizontal direction at the central part in the longitudinal direction of the air outlet 16, part of the air is blown out downward at both ends in the longitudinal direction. Therefore, the air from both ends of the longitudinal direction is difficult to flow along the ceiling. Therefore, contamination of the ceiling surface can be prevented, and horizontal blowing can be ensured as a whole. Thereby, the air blowing direction according to the operating state of the air conditioner can be ensured, and the occurrence of contamination on the ceiling surface can be avoided.

Also, when the openings 18c at both ends in the longitudinal direction of the horizontal vane 18 are notched, or the horizontal vane 18 is formed in a state where the upstream end edge of the air flow gradually rises from the central part in the longitudinal direction to both ends, it can be easily used. The structure realizes the prevention of contamination of the ceiling. In addition, if the size of the opening 18c etc. is set appropriately in advance, the air-conditioned air can be blown downward in an appropriate proportion from both ends of the air blowing port 16, and it is easy to realize the reliable prevention of air blowing while blowing out horizontally as a whole. Structure of ceiling contamination.

Again, when using conventional horizontal blades, the air flow tends to peel off at the ends of the horizontal blades. As a result, sometimes surrounding warm air is drawn in and dew is condensed on the horizontal blades. In the state where the upstream end edge portion gradually rises from the central portion in the longitudinal direction to both ends, since the traveling direction of the air flowing downward from the air blowing port 16 is approximately the same as the direction of the both ends of the horizontal blade 18, it is difficult to cause a blowout. Peeling phenomenon and dew condensation are also difficult to occur.

Also, in the case where the end portion in the longitudinal direction of the air outlet 16 has an enlarged portion 16L, if the opening 18c of the horizontal blade 18, etc. is formed in an area corresponding to the enlarged portion 16L, due to the length of the horizontal blade 18 The amount of air remaining on the inner side of the horizontal blade 18 at both ends of the direction is reduced, so that horizontal blowing can be performed and a structure capable of preventing contamination of the ceiling can be realized.

The best form for carrying out the invention

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

Specifically, the casing 11 is composed of a top plate 12 formed by chamfering four corners of a square into an octagonal shape (not shown), and side plates 13 extending downward from the outer edge of the top plate 12. constitute. The decorative panel 14 has a substantially square plate shape and is attached to the lower end portion of the side plate 13 of the housing 11 . The peripheral portion of the decorative panel 14 is attached along the ceiling 70 so as to be in contact with the lower surface of the ceiling 70 .

Also, as shown in FIG. 2 of the perspective view of the state after the air conditioner 1 is installed on the ceiling, the air suction port 15 is formed in a square shape with an opening in the substantially central portion of the above-mentioned decorative panel 14, and the air suction port 15 is formed along the sides of the air suction port 15 respectively. Four elongated rectangular air outlets 16 are formed right outside the four sides. In addition, in the above-mentioned air inlet 15, an air filter 17 for removing floating matter such as particulate dust contained in the indoor air is provided along the entire surface thereof, and the entire lower surface of the air filter 17 is filtered by a lattice shape. supported by the cover.

In addition, horizontal blades 18 are arranged at the air blowing outlet 16 to adjust up and down the blowing direction of the conditioned air. As shown in the enlarged part in Fig. 3 and Fig. 4 in detail, the outer guide surface of the side wall on the panel peripheral side (the right side of the figure) as the air channel communicating with the air outlet 16 of the decorative panel 14 is substantially vertically downward. The first outer guide surface 16a extending in the opposite direction and the second outer guide surface 16b inclined downward from the lower end of the first outer guide surface 16a to the lower surface of the decorative panel 14 toward the outer peripheral side of the panel, the two outer guide surfaces 16a , 16b are smoothly connected to each other.

The 2nd outside guide surface 16b, the inclination of the central part 16b-c located in the central part of the longitudinal direction of the air outlet 16 is set to be large (about 60 degrees), and the two sides located at both ends of the longitudinal direction of the air outlet 16 are The inclination of the ends 16b-s is set to be small (about 30 degrees). The inclination of the second outer guide surface 16b gradually changes from the central portion 16b-c to both end portions 16b-s. Furthermore, as shown in FIG. 5 which is a perspective view of the air outlet 16 viewed from below, the lower edge 16b-e of the second outer guide surface 16b is formed in an arc shape.

3 and 4, the inner guide surface of the side wall on the inner peripheral side (left side of the figure) of the panel as the air passage communicating with the air outlet 16 consists of a first The inner guide surface 16c and the second inner guide surface 16d gradually inclined obliquely downward from the lower end of the first inner guide surface 16c toward the outer peripheral side of the panel are constituted, and the two inner guide surfaces 16c and 16d are smoothly connected to each other.

The outer guide surfaces 16 a , 16 b are formed on the outer member 14 a of the decorative panel 14 , and the inner guide surfaces 16 c , 16 d are formed on the inner member 14 b of the decorative panel 14 . Also, the outer guide surfaces 16a, 16b of the outer member 14a located on the airflow downstream side of the horizontal blade 18 are curved in substantially the same cross-sectional shape as the horizontal blade 18 (not limited to the curved shape, as long as it is substantially along the shape of the horizontal blade 18). ), in addition, the inner guide surfaces 16c, 16d of the inner member 14b located on the air flow upstream side of the horizontal blade 18 extend vertically downward than the outer guide surfaces 16a, 16b of the outer member 14a, and the air outlet 16 is formed on these Between the outer guide surfaces 16a, 16b and the inner guide surfaces 16c, 16d. The shape of the inside guide surfaces 16c and 16d can be selected arbitrarily.

And, the two wall surfaces facing each other (the outer guide surfaces 16a, 16b and the inner guide surfaces 16c, 16d) of the above-mentioned shape are formed along the entire length of the air outlet 16 in the longitudinal direction (the direction perpendicular to the paper surface), sandwiching The air passage between the two wall surfaces 16a, 16b and 16c, 16d functions as an assisting passage for assisting in changing the flow direction of the conditioned air flow facing the air outlet 16 while rectifying it.

The above-mentioned horizontal blade 18 is a long plate-shaped member as shown in FIG. 6, and is bent only in its width direction. Arms 18a, 18a protruding toward the inner surface of the horizontal blade 18 are respectively integrally provided at both ends of the length direction of the horizontal blade 18, and arms 18a, 18a protruding outward along the length direction of the horizontal blade 18 are respectively formed at the ends of each arm 18a. Extended connection pins 18b, 18b. The horizontal vane 18 is swingably attached to the air outlet 16 about the connection pins 18b, 18b. Specifically, the horizontal blade 18 is configured to be swingable with the connecting pins 18b, 18b as the center of rotation by a motor not shown. In the above structure, when the conditioned air is blown to the bottom, the horizontal vane 18 is set downward as shown in FIG. Set up.

As a feature of this embodiment, notches 18c are formed as openings through which air-conditioned air passes, at the airflow upstream side edge portions of both longitudinal ends of the horizontal blade 18 . The notch 18c is approximately 1/4 of the length in the longitudinal direction of the horizontal blade 18, and is formed at the airflow upstream side edge portions at both ends in the longitudinal direction. By providing the cutouts 18c, the width of both end portions 18e of the horizontal blade 18 is narrowed to about 2/3 of the central portion 18d. The specific dimensions of the horizontal blade 18 can be made, for example, about 480mm in total length, about 37mm in width (the width of the central part 18d), about 25mm in width at both ends 18e, and about 120mm in length of the notch 18.

In addition, the above-mentioned fan 20 is provided at a substantially central position inside the casing 11 . This fan is a so-called turbofan in which blades 23 are held between a shroud 21 and a hub 22 . The drive shaft 26 of the fan motor 25 mounted on the top plate 12 of the housing 11 is inserted and fixed on the hub 22 of the fan 20, and the fan 20 is driven to rotate by the driving force of the fan motor 25, so that The air sucked in from below is sent radially to the side. Further, a tapered hole 27 for guiding the air flowing into the casing 10 from the air inlet 15 to the fan 20 is provided below the fan 20 .

The heat exchanger 30 is a so-called cross-flow fin heat exchanger constituted by a plurality of plate-shaped fins 31 arranged parallel to each other and heat transfer tubes 32 provided through the fins 31 . The heat exchanger 30 surrounds the fan 20 and has a rectangular cylindrical shape in plan view, and is connected to an outdoor unit through a refrigerant pipe (not shown). The heat exchanger 30 functions as an evaporator during the cooling operation and as a condenser during the heating operation to adjust the temperature state of the air sent from the fan 20 . Further, a water receiving pan 33 for receiving drain water is disposed below the heat exchanger 30 .

Adopt above-mentioned structure, in the housing 11 of air conditioner 1, be formed with the air that passes through air filter 17, tapered hole 27, fin 20 and heat exchanger 30 to air outlet 16 from air inlet 15 of decorative panel 14. flow channel W. And, the fan 20 is driven during the air-conditioning operation, and the indoor air sucked into the casing 10 from the air inlet 15 through the air filter 17 flows in the air flow passage W in the order of the tapered holes 27, the fins 20 and the heat exchanger 30. The refrigerant flows through the heat exchanger 30 to perform heat exchange with the refrigerant to adjust the temperature (cooling for cooling operation, heating for heating operation), and then blows out as conditioned air from the air outlet 16 to the indoor space. Air conditioning of this indoor space is performed.

Here, first of all, when it is required to blow out the conditioned air relatively downward, as shown in the above-mentioned FIG. Between the sidewalls 16a, 16b on the outer peripheral side of the panel and the sidewalls 16c, 16d on the inner peripheral side of the panel, the air is blown downward along the horizontal blade 18 as indicated by the arrow S in FIG. 4 .

In addition, when making the so-called horizontal blowing state during cooling operation, as shown in the above-mentioned FIG. The central portions 16b-c are substantially parallel. In this way, the conditioned air flows curvedly along the central portion 18d of the horizontal blade 18 at the central portion of the air outlet 16, and the direction of its streamline changes smoothly, as shown in S1 in FIG. Between the second outer guide surface 16b on the outer peripheral side and the horizontal blade 18, the air is blown out from the air outlet 16 at an angle close to parallel to the lower surface of the ceiling 70 (for example, the angle formed with the lower surface of the ceiling 70 is approximately 30°-35°). .

Also, at both ends of the air outlet 16, a part of the conditioned air flowing downward in the air passage W passes through the gaps 18c at both ends 18e of the horizontal vane 18, and flows as shown by the arrow S2 in FIG. 3 . Blow out below. Therefore, at both end portions of the air outlet 16, the flow rate of the air flowing in the direction of the arrow S1 decreases, and the air hardly flows along the ceiling surface. In addition, since the two end portions 16b-s of the second outer guide surface 16b are made more upright than the central portion 16b-c (shape with a smaller inclination), the air blown out from both ends of the air outlet 16 is more stable. It is difficult to flow in the direction of arrow S1.

In the prior art, for example, at the portion where the air blowing speed is low (both ends of the air blowing port 16) in the ceiling-mounted air conditioner, since the air flow tends to adhere to the bottom of the ceiling 70, the horizontal blade 18 is used during cooling operation. The blowing direction of the conditioned air is relatively upwards, and when it is made about 30°-35° below the relative ceiling 70, the air flow will flow along the below of the ceiling 70, and will be generated at the area D as shown by the imaginary line in Figure 2 Ceiling contamination is distributed in a roughly V-shape at each air outlet. However, with the air conditioner 1 of the present embodiment, especially in the cooling operation in which the air-conditioning air is required to be blown out horizontally, since the blown air from both ends of the air outlet 16 is difficult to flow along the lower surface of the ceiling 70, even if the blown air from the air outlet 16 is The blowing direction of the conditioned air blown out by the air outlet 16 is close to, for example, about 30°-35° relative to the lower side of the ceiling 70 by the horizontal blade 18 in the central part of the air outlet, so as to prevent ceiling pollution.

Also, in this embodiment, since the notch 18c of the horizontal blade 18 is only formed in about 1/4 of the two ends 18d of the horizontal blade 18, it is possible to prevent contamination of the ceiling and to satisfy overall sufficient horizontal blowing.

Therefore, according to the air conditioner 1 of the present embodiment, especially during the cooling operation in which the air-conditioned air is required to be blown out horizontally, the blowing direction of the air-conditioned air can be made closer to the horizontal direction than in the prior art while preventing contamination of the ceiling. Ensure air-conditioning efficiency and eliminate the sense of imbalance (ventilation) for indoor occupants.

In addition, the present invention is not limited to the above-described embodiments, and includes other various embodiments.

For example, in the above-mentioned embodiment, although the notches 18c are formed as openings on the both ends 18c of the horizontal blades 18, it is also possible to provide through holes on the horizontal blades 18 instead of the notches 18c, as long as the structure is blown out horizontally. Air may be blown downward from both ends of the air outlet 16 at this time.

Moreover, the shape and size of the said horizontal blade 18 etc., and the size and shape of the notch (opening part) 18c are only an example, and it can change suitably according to the shape etc. of an actual product, of course.

When the opening 18c is formed as a notch, the notch 18c can be formed, for example, in the shape shown at the end of the horizontal vane 18 in FIGS. 7( a ) to 7 ( c ). FIG. 7( a ) is an example in which the airflow upstream side edge portion of the longitudinal end portion of the horizontal blade 18 is formed in an arc shape, and FIG. 7( b ) is an example in which the airflow upstream side edge portion is formed in an inclined straight line. . FIG. 7( c ) is an example in which the airflow upstream side edge portion is formed into an arc shape opposite to that of FIG. 7( a ).

In addition, as shown in FIG. 7( d ), the end portion of the horizontal blade 18 may be made into a three-dimensional shape twisted from the central portion in the longitudinal direction of the horizontal blade 18 to both ends so that the edge portion on the upstream side of the airflow gradually stands up. to replace the opening 18. In this case, it is difficult for the air to separate from the ends of the horizontal blades 18 . At the ends of the horizontal blades 18, it is difficult to draw in ambient warm air, so there is also an advantage that dew condensation is difficult to occur.

As described above, in the present invention, on both ends of the central portion in the longitudinal direction, as long as the airflow upstream side edge portions are formed so that the airflow passing through the negative pressure surface side of the horizontal blade 18 (the back side of the horizontal blade 18 (air) The shape in which the downward air flow (see S2 in FIG. 3 ) on the inner guide surface 16c, 16d side of the air outlet 16, that is, on the inner side in the blowing direction) increases.

Also, in the above-mentioned embodiment, although the present invention is applied to a so-called ceiling-embedded four-direction blowing type air conditioner 1 having a turbo fan and blowing air-conditioned air in four directions, it is not limited thereto. This is a so-called ceiling-buried 2-direction blowing type air conditioner that blows conditioned air in one direction.

In addition, the present invention is not limited to a ceiling-embedded air conditioner, but is also applicable to an intermittent type air conditioner. As shown in FIG. 8 , an intermittent air conditioner 50 is an air conditioner in which an air outlet portion 51 installed on a ceiling 70 is connected to an air conditioner body 53 installed on a roof of a building through an air supply duct 52 . Even in the air outlet portion 51 of the air conditioner 50, at both ends in the longitudinal direction of the horizontal blade 18 disposed at the air outlet 16, openings as shown in FIGS. 7(a) to 7(d) are provided. 18c, the same effect as that of the above-mentioned embodiment can be exhibited.

Also, as shown in FIG. 9, for example, in a ceiling-embedded air conditioner, the piping and the electrical box are disposed at the corners of the casing 11. In addition, the four blowing openings of the decorative panel 14 need to be closed for appearance reasons. Since the shapes are all made the same, the opening length of the air passage in the longitudinal direction may be different between the case 11 side and the decorative panel 14 side. In such a case, the air outlet 16 has an enlarged portion 16L extending the length of the opening of the air passage in the longitudinal direction of the air outlet 16 at the portion facing the interior space at the end in the longitudinal direction. Also, the length of the enlarged portion 16L varies depending on the air outlet.

Therefore, the opening 18c such as a notch formed on the airflow upstream side end edge of both ends in the longitudinal direction of the horizontal blade 18 or a portion corresponding to the opening 18c can be formed to have a length corresponding to the enlarged portion 16L of the air outlet 16. . In the case where there is no opening 18c or the like or when the opening 18c is short, the air blown out tends to stay at both ends of the horizontal blade 18. Both ends in the longitudinal direction are turned downward, so the amount of air stagnant on the inner side of the horizontal blade 18 can be reduced, and the ceiling can be prevented from being polluted while blowing out horizontally. In addition, this is also the same in the intermittent type air conditioner 50 .

In addition, in the above-mentioned embodiment, although the inclination of the second outer guide surface 16b of the air blowing port 16 is set so that the two ends 16b-s are closer to the vertical angle than the central part 16b-c, this is not necessarily the case. Formed in this way, the second outer guide surface 16 can also be made to conform to the inclination of the central portion 16b-c of the above-mentioned embodiment, for example, over the entire area along the air outlet 16.
