Description

Air conditioner

Technical Field

Embodiments of the present invention relate to a flap structure of a ceiling-embedded air conditioner, in which a flap guides a blowing direction of cool air and hot air blown out from a blowing port of a decorative panel.

Background

The ceiling-embedded type air conditioner has a main unit installed in a ceiling. The bottom opening of the main machine forms a suction inlet. The suction opening is covered by a decorative panel. The decorative panel is exposed to the room from the ceiling.

The decorative panel of the general air conditioner includes a suction grill. The suction grille is square and is opposite to the suction inlet of the main machine. The decorative panel forms an air outlet on the periphery of the suction grille. The air outlet is elongated along four sides of the suction grille. The air outlet blows out cold air or hot air in four directions.

Flaps are provided at the four outlets of the decorative panel. When the air conditioner is cooling, the flap guides the blown-out cold air to flow from the air outlet in the horizontal direction. When the air conditioner heats, the flap guides the blown warm air to flow downwards.

In a conventional air conditioner, in order to improve the directivity of the flow of cold air in the horizontal direction during cooling operation, a flap is projected downward and has a cross-sectional shape curved in an arc. Furthermore, the flap forms a1 st end and a 2 nd end along the length direction, respectively. The 1 st end and the 2 nd end separate the flap in the width direction, wherein the 1 st end and the 2 nd end have a narrower width than a central portion of the flap.

Therefore, when the air conditioner is in refrigeration operation, cold air is blown out in a downward inclined direction through the 1 st end and the 2 nd end of the flap, and dust in the air is prevented from polluting the ceiling and leaving stains.

The 1 st end and the 2 nd end of the flap of the conventional air conditioner are narrower than the central part. Therefore, when the air-conditioning stop operation is performed, even if the flap has closed the air outlet, the inside of the air outlet can be seen through the 1 st end and the 2 nd end of the flap, which is a problem in design.

In order to solve this problem, patent document 1 discloses an air conditioner in which the shape of the side wall of the air outlet is defined, the air after heat exchange blown out from the center of the air outlet flows in the horizontal direction, and the air blown out from the both ends of the air outlet flows in the diagonally downward direction.

The flap disposed at the air outlet has a central portion and two side portions, which are trisected. The central portion of the flap is a key factor for guiding the cool air blown out from the air outlet to flow in the horizontal direction, and the downstream end of the central portion is curved and directed in the horizontal direction. The both side portions of the flap are a key factor for guiding the cool air blown out from the air outlet to flow in a diagonally downward direction, and the downstream ends of the both side portions are also curved and point in a further downward direction than the downstream end of the central portion.

Further, the flap has a pair of slits between the central portion and both side portions in the width direction of the flap to partition them. Specifically, the flap is constructed from one elongated sheet of material. The sheet extends along the edges in the length direction and includes a stack of slits in the width direction dividing the sheet into three compartments. The curvature of the central portion has a greater curvature and the central portion is also curved on both sides, but with a lesser curvature than the central portion.

Thus, the central portion of the sheet forms the central portion of the flap, and the sides of the sheet form the sides of the flap

Disclosure of Invention

[ problem to be solved by the invention ]

In existing air conditioners, the slit of the flap is cut into the upstream edge of the flap from the downstream edge of the flap, with the end of the slit being directly in front of the upstream edge of the flap. Therefore, the flap is fixed between the central portion and both end portions only by the portion where the upstream edge of the flap is continuous, and most of the central portion and both end portions of the flap are separated by the slit.

Therefore, the shapes of the central portion and both end portions of the flap are difficult to maintain, and the strength of the flap is also difficult to ensure.

The invention aims to simplify the structures of a blow-out opening and a flap and obtain an air conditioner, wherein the flap of the air conditioner has certain strength.

Detailed Description

[ 1 st embodiment ]

The following describes embodiment 1 with reference to fig. 1 to 5.

Fig. 1 is an oblique view illustrating a ceiling-embedded type air conditioner. Fig. 2 is a plan view of the ceiling-embedded air conditioner as viewed from the direction of the decorative panel.

The air conditioner 1 mainly includes a main unit 1a installed in a ceiling and a decoration panel 2 installed at the bottom of the main unit 1 a. As shown in fig. 5, the main unit 1A is inserted into a room through an opening 1A provided in a ceiling panel a, and is suspended downward from a cross member on the inside of the ceiling by a plurality of suspension bolts.

As shown in fig. 1, the main unit 1a includes a case 3 made of a metal plate. The housing 3 has a box-shaped structure opened downward, and includes a top plate 3a and a side surface 3 b. The inner peripheral surface of the housing 3 is entirely covered with a foam-type heat insulating material. Therefore, the main unit 1a has a heat insulating structure.

The blower is provided in the center of the main body 1 a. The blower, which is a so-called turbofan, sucks air along a longitudinal direction and discharges the air to the surroundings. Further, the bottom of the main body 1a has a horn-shaped suction port 6 a. The suction inlet 6 is located at the suction end of the blower.

A heat exchanger is arranged around the side where the blower protrudes. The heat exchanger is rectangular in shape and surrounds the blower. The lower part of the heat exchanger is provided with a condensed water tray. When the air conditioner operates in a cooling mode, the condensed water tray receives condensed water generated by the heat exchange effect of the heat exchanger. The condensed water retained by the condensed water disk is discharged to the outside of the air conditioner 1 through the condensed water pump.

The decorative panel 2 covers an indoor portion of a lower end of the casing 3. The decorative panel 2 is formed in a beautiful shape using a synthetic resin material. The decorative panel 2 is exposed to the room from the lower end of the ceiling panel a, and covers the gap between the outer peripheral surface of the main body 1a and the opening a1 of the ceiling panel a.

As shown in fig. 1 and 2, the decorative panel 2 includes a suction grill 4 and a panel main body 5. The suction grill 4 is disposed at a substantially central portion of the decorative panel 2. The suction grill 4 has a square shape and can be removed from the housing 3 by a lifting or rotating structure. The panel body 5 has a rectangular frame shape and is connected to the housing 3. The panel body 5 surrounds the suction grill 4.

For the best representation of fig. 1, the suction grill 4 is opposed to the panel main body 5 and slightly protrudes downward. Therefore, if the suction grill 4 and the panel main body 5 are at the same level, a height difference that can be distinguished by naked eyes can be generated between the suction grill 4 and the panel main body 5.

As shown in fig. 2, the suction grill 4 includes a rectangular edge portion and a grill portion 4a surrounded by the edge portion. The four sheet portions forming the edge portion are elongated flat plates of a prescribed width. The grill portion 4a is located at the center of the suction grill 4. The back of the grid part 4a contains a filter screen which can be taken out outwards to play a supporting role. The grill portion 4a faces the suction port 6 of the main body 1.

When the filter screen is maintained, the suction grille 4 is lowered or rotated downward. Accordingly, the filter can be taken out from the suction grill 4 while the suction port 6 of the main unit 1 is opened, and the filter can be cleaned on the floor.

As shown in fig. 1 and 2, the panel body 5 of the decorative panel 2 has four air outlets 7. The air outlets 7 blow out the air after heat exchange by the heat exchanger in four directions of the decorative panel 2, and four air outlets are arranged in the panel main unit 5.

Specifically, the panel main body 5 includes corner covers 4c located at four corners of the panel main body 5 and a panel sheet portion 4b between the corner covers 4 c. The panel piece portion 4b extends in parallel along the edge portion of the suction grill 4. Therefore, the edge of the suction grille 4, the panel piece 4b, and the adjacent corner cover 4c surround the air outlet 7. Around the suction grille 4, two adjacent air outlets 7 are arranged with the corner covering 4c therebetween, and the two adjacent air outlets 7 are arranged in a vertical positional relationship.

As shown in fig. 2, each of the blow-out ports 7 has an elongated opening shape along the edge of the intake grille 4. Specifically, the 1 st dimension of the air outlet 7 in the longitudinal direction is L1, the 2 nd dimension in the width direction is L2, and the 2 nd dimension L2 is much shorter than the 1 st dimension L1. Further, both ends in the longitudinal direction have a pair of end faces d, which are restrained by corner covers 4c of the panel main body 5. The end surface d extends in the width direction of the air outlet 7 and stands vertically.

As shown in fig. 5, the air outlet 7 has an inner wall 7a and an outer wall 7 b. The inner wall 7a forms an inner surface of the air outlet 7 along the longitudinal direction of the air outlet 7. Similarly, the outer wall 7b forms an outer wall of the air outlet 7 along the longitudinal direction of the air outlet 7. The inner wall 7a and the outer wall 7b are opposed to each other in the width direction of the air outlet 7, and extend downward and are inclined outward of the panel body 5.

Flaps 8 are arranged at the four air outlets 7 of the panel main body 5, respectively. The flap 8 can change the flow direction of the air blown out into the room from the air outlet 7, and the structure of the flap 8 will be described below.

Fig. 3 is an oblique view of the flap 8, and fig. 4 is an oblique view enlarged at fig. 3F 4. Fig. 5 is a sectional view showing the posture of the flap 8 during the cooling operation of the air conditioner 1.

The flap 8 is of the same material as the suction grill 4 and the panel body 5. The flap 8 is also preferably of the same colour as the suction grill 4 and the panel body 5.

As shown in fig. 3, the flap 8 is an elongated flat plate, and can be fitted tightly into the outlet 7 in accordance with the opening shape of the outlet 7. However, in order to prevent the flap 8 from obstructing the opening and closing of the air outlet 7, the flap 8 is slightly smaller in size than the air outlet 7. Further, when the flap 8 closes the blow-out port 7, the size of the flap 8 is preferably set so as to prevent the edge of the blow-out port 7 and the edge of the flap 8 from forming a significant gap.

The flap 8 includes an outwardly exposed decorative surface 8a, an inner side surface 8b on the back of the decorative surface 8a, and a1 st side edge a and a 2 nd side edge b extending along the length of the flap 8. The decorative surface 8a and the back surface 8b are flat surfaces. The 1 st side edge a is located on the upstream side of the air outlet 7 from which air is blown out, along the width direction of the flap 8. The 2 nd side edge b is located on the downstream side of the air blown out from the air outlet 7 in the width direction of the flap 8.

Moreover, the flap 8 includes a1 st end portion 8c, a 2 nd end portion 8d, and an intermediate portion 8 e. The 1 st end portion 8c is located at one longitudinal end of the flap 8, the 2 nd end portion 8d is located at the other longitudinal end of the flap 8, and the intermediate portion 8e is located between the 1 st end portion 8c and the 2 nd end portion 8 d.

The 1 st end 8c of the flap 8 is formed with a support wall 9 a. Likewise the 2 nd end 8d of the flap 8 is formed with a support wall 9 b. The support walls 9a and 9b are located at both ends of the flap 8 in the longitudinal direction and stand on the back surface 8b of the flap 8. The outer side surfaces of the support walls 9a, 9b are provided with support shafts 10a and 10b, respectively. The support shafts 10a and 10b are on the same axis along the length of the flap 8.

The support shafts 10a and 10b assist the rotational configuration (not shown in the drawings) inside the air outlet 7. Therefore, in the present embodiment, the flap 8 can rotate about the support shafts 10a and 10b at an intermediate position between the 1 st position and the 2 nd position. The flap 8 closes the air outlet 7 in the 1 st position and is horizontally inside the air outlet 7. The flap 8 opens the air outlet 7 in the 2 nd position and stands inside the air outlet 7.

As shown in fig. 3 and 4, the intermediate portion 8e of the flap 8 and the reinforcing portion 11 are integrally formed. The reinforcing portion 11 includes a flat reinforcing plate 11 a. The reinforcing plate 11a extends from the 1 st lateral edge of the flap 8.

The reinforcing plate 11a is formed with upright portions 11b and 11c bent at right angles at both ends in the longitudinal direction. The upward standing portions 11b and 11c extend in the width direction of the flap 8, and the front ends thereof are fixed to the back surface 8b of the flap 8. Therefore, the reinforcing plate 11a is disposed in parallel with the back surface 8b of the flap 8.

A gap c is formed between the reinforcing plate 11a and the back surface 8b of the flap 8, corresponding to the height of the upward standing portions 11b and 11 c. The gap c is a narrow air passage 12 in the flap 8.

According to the present embodiment, the one upward standing portion 11b is located on the back surface 8b of the flap 8, and the other upward standing portion 11c is located on the back surface 8b of the flap 8 and separated from the other support wall 9 b. Furthermore, the reinforcing plate 11a is distanced from the 2 nd lateral edge 8b of the flap 8. Therefore, the auxiliary plate 11a also has a region in the back surface 8b of the flap 8, in which the air blown out from the air outlet 7 flows downward.

As shown in fig. 3, the connecting rib 13 is formed integrally with the intermediate portion along the longitudinal direction of the reinforcing plate 11, and the connecting rib 13 extends along the width direction of the flap 8 and is connected to the reinforcing plate 11a and the inner surface 8b of the flap 8 in the air passage 12. In other words, the connecting ribs 13 support the intermediate portion of the auxiliary plate 11a, preventing the intermediate portion of the reinforcing plate 11a from bending deformation.

The number and position of the connecting ribs 13 are not particularly limited. The increased number of the connecting ribs 13 increases the strength of the auxiliary plate 11a, but also increases the ventilation resistance in the air passage 12.

In this embodiment, the thickness of the flap 8 is fixed except for the portion opposite to the reinforcing plate 11 a. Specifically, the thickness of the flap 8 is continuously decreased from the 2 nd side edge to the 1 st side edge in a portion opposed to the auxiliary plate 11 a.

Therefore, the portion of the flap 8 facing the reinforcing plate 11a becomes gradually thinner, and the air blown out from the air outlet 7 starts flowing along the upstream side, and the thickness of the flap 8 becomes thinner, so that the ventilation resistance of the air blown out from the air outlet 7 can be effectively reduced.

The thickness of the flap 8 does not need to be changed subtly as in the above-described position opposed to the auxiliary plate 11, and the thickness of the flap 8 as a whole may be uniform.

According to the air conditioner 1 of embodiment 1, the flap 8 disposed at the air outlet has an elongated flat plate-like structure in accordance with the opening shape of the air outlet 7, and the decorative panel 8a exposed to the indoor space has a flat surface.

Therefore, after the operation of the air conditioner 1 is stopped, the flap 8 is rotated to the 1 st position, and the flap 8 is brought into a horizontal state to completely close the air outlet 7. When the flap 8 closes the air outlet 7, the flap 8 is positioned at the same level as the panel piece portion 4b and the corner cover 4c of the panel main body 5, and the panel main body 5 looks like a monolithic structure.

Therefore, when the air conditioner 1 is stopped, the inside of the main body 1a cannot be seen through the air outlet 7, and the appearance of the air conditioner 1 can be maintained well.

In addition, the flap 8 of the present embodiment is made of the same material as the suction grill 4 and the panel main body 5, and has the same color as the decorative panel 8a and the decorative panel back surface 8b, so that the flap 8, the suction grill 4, and the panel main body 5 are perceived as a single body, and thus, when the decorative panel 2 is viewed upward indoors, the user does not feel uncomfortable. Thus, the aesthetic appearance of the trim panel 2 is improved, being able to match any ceiling, which is a simple and smart design.

In the cooling operation of the air conditioner 1, the flap 8 can be adjusted to a desired angle by using a remote controller as shown in fig. 5, and the 1 st side edge can be directed downward. Meanwhile, with the operation of the blower, indoor air enters the main unit 1a through the suction port 6 of the suction grill 4.

The indoor air sucked into the main unit 1a passes through the heat exchanger and exchanges heat with the refrigerant, and the air temperature decreases to become cool air, and the cool air is blown into the room from the air outlet 7, thereby cooling the room.

The flap 8 disposed in the air outlet 7 changes the direction of the cool air blown out from the air outlet 7. Specifically, the back surface 8b of the intermediate portion 8e of the flap 8 includes the reinforced portion 11, and the cool air blown out from the air outlet 7 is divided into a component X1 flowing along the decorative surface 8a of the flap 8, a component X2 flowing along the narrow air passage 12 of the reinforced portion 11, a component X3 flowing along the upper portion of the auxiliary plate 11a of the reinforced portion 11, and a component X4 flowing away from the reinforced portion 11 on the back surface 8b of the flap 8 in the direction indicated by arrows in fig. 3 and 5.

The ventilation path 12 of the reinforcing portion 11 is restricted by the gap c having the same height as the upward standing portions 11b and 11c of the auxiliary plate 11a, and thus forms a concentrated ventilation area inside the air outlet 7. Therefore, the cold air component 2 is concentrated when passing through the ventilation passage 12, and the flow speed of the cold air passing through the ventilation passage 12 is higher than the flow speed of the cold air leaving the reinforcement portion 11 and flowing along the back surface 8b of the flap 8.

In other words, the intermediate portion 8e of the flap 8 increases the flow velocity of the cold air guided by the flap 8. In contrast, the flap 8 guides the cold air at a slower flow speed in the first end 8c and the second end 8d of the flap 8 than in the middle 8 e.

As a result, of the cold air blown out from the air outlet 7, the cold air guided by the intermediate portion 8e of the flap 8 has a high flow velocity, and as shown by an arrow X2 in fig. 3, the air has a stronger directivity, and becomes horizontal air that can reach a distant place. On the other hand, among the cold air blown out from the air outlet 7, the cold air guided by the 1 st end portion 8c and the 2 nd end portion 8d of the flap 8 has a low flow velocity and, as shown by an arrow X4 in fig. 3, has a lower directivity than the cold air guided by the intermediate portion 8e of the flap 8.

Therefore, the cool air guided by the 1 st end portion 8c and the 2 nd end portion 8d does not reach a far place, but becomes wind in a diagonally downward direction. The wind obliquely downward is more downward than the angle of inclination of the flap 8, or more downward than the preset direction of the flap 8.

Therefore, the cool air blown out from the air outlet 7 can flow in both the horizontal direction and the diagonally downward direction by the guidance of the flap 8.

Furthermore, in the present embodiment, the inner faces 8b of the 1 st and 2 nd ends 8c, 8d of the flap 8 remote from the reinforcement 11 are adjacent to the corner covering 4 c. As described above, the cool air guided to the back of the 1 st end 8c and the 2 nd end 8d has poor directivity and spreads around the air outlet 7.

Therefore, in the flap 8 of the present embodiment, the flap 8 is cut at a constant width along both longitudinal end portions, and compared to the conventional flap, even if the corner cover 4c passes through the extension line of the diagonal line e of the decorative panel 2, the cool air can be surely flowed in the diagonally downward direction from the air outlet 7.

Therefore, indoor dust can be prevented from adhering to the lower surface of the ceiling panel a and leaving a mark.

Incidentally, when the flap 8 is of an elongated flat plate-like structure and the direction of the cool air blown out from the air outlet 7 is changed, if the thickness of the flap 8 is not increased, or if the flap 8 is not bent in the width direction, the strength of the flap 8 becomes insufficient, which is one cause of deformation of the flap 8.

However, in embodiment 1, the reinforcing portion 11 is disposed on the inner surface 8b of the flat-plate-shaped flap 8, and even if the thickness of the flap 8 is reduced to some extent, the strength of the flap 8 can be secured without bending the flap 8 in the width direction.

Therefore, the flap 8 is prevented from being bent in the longitudinal direction, and the trim 8a of the flap 8 can be formed into a flat surface. Thus, the flap 8 has a simple shape, and the appearance of the decorative panel 2 is improved.

[ example 2]

Fig. 6 discloses and illustrates embodiment 2.

In embodiment 2, the configuration of the flap 8A of the air conditioner is different from that in embodiment 1. Since the configuration of the flap 8A has the same parts as those of the first embodiment, the same reference numerals are used for the parts having the same configuration as that of embodiment 1, and the description thereof is omitted.

As shown in fig. 6, the 2 nd side edge of the flap 8A is integrated with the wind direction guide 15. The airflow direction guide 15 is formed in a rib shape, changes the airflow direction of the back surface 8b of the flap 8A, and causes the flap 8A to flow the air blown out from the air outlet 7 to the downstream side.

The air guide 15 extends entirely along the longitudinal direction of the flap 8A, and stands upright on the back surface 8b of the 2 nd side edge b of the flap 8A.

According to the present embodiment, the wind direction guide 15 corresponds to the reinforcing plate 11, and includes a central portion 15; a first side portion 15b is included corresponding to the 1 st end portion 8c of the flap 8A, and a 2 nd end portion 15c is included corresponding to the 2 nd end portion 8d of the flap 8A.

The height H1 of the 1 st and 2 nd side portions 15b, 15c of the airflow direction guide 15 is lower than the height H2 of the central portion 15 a. Therefore, a step S is formed between the center portion 15a and the 1 st side portion 15b and between the center portion 15a and the 2 nd side portion 15c along the height direction of the airflow direction guide 15.

According to the embodiment 2, the cold air X2 guided by the middle portion 8e of the flap 8A and the cold air X4 guided by the 1 st end portion 8c and the 2 nd end portion 8d of the flap 8A reach the 2 nd side edge b via the downstream end of the flap 8A, and come into contact with the wind direction guide 15 standing upward at the 2 nd side edge.

As a result, the angle at which the cold air flowing obliquely downward from the air outlet 7 hits the airflow direction guide 15 along the oblique direction of the flap 8A and is blown out changes. Therefore, the opening angle of the flap 8A can be increased, the volume of the cool air blown out from the air outlet 7 can be secured, the cool air can be guided in a substantially horizontal direction along the lower surface of the ceiling a, and the feeling of flow of the air can be alleviated.

Further, the height H1 of the 1 st side portion 15b and the 2 nd side portion 15c of the wind direction guide 15 of the flap 8A is lower than the height H2 of the center portion 15 a. Therefore, the cool air X4 guided by the 1 st and 2 nd ends 8c and 8d of the flap 8A is blown out diagonally downward along the tilt direction of the flap 8A, and only a small amount of the cool air is blown out into the room close to the horizontal. Thus, the dust can be prevented from leaving marks, and the flowing feeling can be eliminated.

[ modification 1 of embodiment 2]

Fig. 7 discloses a modification 2 related to embodiment 2. Fig. 7 discloses a flap 8B having substantially the same construction as the flap 8A of embodiment 2. Therefore, in modification 1, the same reference numerals are used for the same constituent elements as in embodiment 2, and the description thereof is omitted.

The height H of the wind direction guide 15 of the flap 8B disclosed and shown in modification 1 is constant along the longitudinal direction of the flap 8B. The rest of the constitution is the same as that of the flap 8A in embodiment 2.

According to modification 1, the cold air X2 is guided by the middle portion 8e of the flap 8B, and the cold air X4 is guided by the 1 st end portion 8c and the 2 nd end portion 8d of the flap 8B, and they come into contact with the wind direction guide 15 when reaching the 2 nd side edge B from the downstream portion of the flap 8B.

As a result, the cool air is guided in an oblique direction along the flap 8B from the air outlet 7 to an obliquely downward direction, and the blowing direction changes to a horizontal direction after contacting the airflow direction guide 15. Therefore, when the opening angle of the flap 8B is increased, the volume of cool air blown out into the room from the air outlet 7 can be ensured, and the cool air can be guided in a substantially horizontal direction along the lower surface of the ceiling panel a, thereby alleviating the feeling of flow.

[ modification 2 of embodiment 2]

Fig. 8 discloses a modification 2 related to embodiment 2.

Modification 2 discloses a flap 8C, and a wind direction guide 15 is provided on the 2 nd side edge of the flap 8C, and is disposed to face only the downstream side of the auxiliary portion 11. Therefore, in the back surface 8b of the flap 8C, the regions corresponding to the 1 st end 8C and the 2 nd end 8d of the flap 8C are flat in configuration.

According to embodiment 2, of the cold air blown out from the air outlet 7, the cold air blown out from the central portion in the longitudinal direction has a main flow direction, the cold air blown out from the opposite end portions in the longitudinal direction has a secondary flow direction, the main flow direction of the cold air is higher than the flow rate of the secondary flow direction, and the air outlet angle is changed to the horizontal direction after contacting the upper surface of the auxiliary plate 11a of the flap 8C inclined inside the air outlet 7. At the same time, the main flow direction of the cold air is pressed while passing through the ventilation road 12 of the auxiliary portion 11, and the flow speed becomes faster.

The cool air that contacts the auxiliary plate 11a mainly flows toward and through the ventilation path 12 mainly flows toward and contacts the wind direction guide 15 when reaching the lower end of the flap 8C. As a result, the cool air mainly flows in the oblique direction along the flap 8C and is guided in the oblique downward direction, and the blowing angle changes to the horizontal direction after coming into contact with the wind direction guide 15.

Therefore, the opening angle of the flap 8C is increased, the amount of cool air blown out into the room from the air outlet 7 can be secured, and the main flow direction of the cool air can be guided to the bottom surface of the ceiling panel a, thereby alleviating the feeling of flow.

On the other hand, the cold air having a slower flow rate than the main flow flows in the secondary flow direction along the inner surfaces 8C of the 1 st and 2 nd ends of the flap 8C. The downstream ends of the inner surfaces 8b of the 1 st end 8C and the 2 nd end 8 do not have the wind direction guides 15, and the secondary flow of the cold wind spreads downward more than the flap 8C, or downward more than the direction of the flap 8C.

Therefore, the cold air blown out from the air outlet 7 can be guided in both the horizontal direction and the diagonally downward direction by the flap 8C having a flat plate shape, and the cold air can be diffused into the room in a wide range.

Further, according to modification 2, the cool air is guided by the inner surfaces 8b of the 1 st end portion 8c and the 2 nd end portion 8d, and spreads in the diagonally downward direction of the air outlet 7 as described above. Therefore, even if the decorative panel 2 is located on the extension of the diagonal line e, the cooling air can be surely flowed in the diagonally downward direction to the air outlet 7.

Therefore, it is possible to prevent indoor dust from adhering to the lower surface of the ceiling panel a and leaving traces.

[ modification 3 of embodiment 2]

Fig. 9 discloses and shows a modification 3 having relevance to embodiment 2. Fig. 9 discloses a flap 8D having partly the same construction as the flap 8A of embodiment 2. Therefore, in modification 3, the same reference numerals are used for the same components as those in embodiment 2, and the description thereof is omitted.

As shown in fig. 9, the thermal insulating material 20 is attached to the region of the back surface 8b of the flap 8D that faces the 1 st end 8c and the 2 nd end 8D of the flap 8D. The heat insulating material 20 may be flat plate-like foamed polyurethane.

In modification 3, as in modification 2 described above, the cool air having a low flow rate flows along the 1 st end 8c and the back surface 8b of the 2 nd end 8D of the flap 8D in the second direction. At this time, even if the amount of the cool air blown out from the air outlet 7 is only a little, the cool air can be guided to the decorative panel 8a of the flap 8D. Here, if the cold air temperature is set low, frost formation may occur in the area between the 1 st end 8c and the 2 nd end 8D of the flap 8D in the trim surface 8a of the flap 8D.

In the flap 8D of modification 3, the heat insulating material 20 is bonded to the inner surfaces 8b of the 1 st end portion 8c and the 2 nd end portion 8D, respectively. Therefore, the problem that the decorative panel is frosted due to the temperature difference and is not frosted and dripped can be avoided.

Incidentally, the heat insulating material 20 disclosed and shown in modification 3 can also be applied to the flap 8 of embodiment 1, the flap 8A of embodiment 2, the flap 8B of modification 1, and the flap 8C of modification 2.

[ example 3]

Fig. 10 discloses and shows embodiment 3. In embodiment 3, the configuration of the air outlet 7 of the decorative panel 2 is different from that in embodiment 1. The other constitution is basically the same as that of embodiment 1. Therefore, in embodiment 3, the same reference numerals are used for the same constituent elements as in embodiment 1, and the description is omitted.

As shown in fig. 10, the outer wall 7b constituting the outer surface of the air outlet 7 is formed with a vertical portion 30. The vertical portion 30 has a vertical surface 30a at an intermediate position along the height direction of the outer side wall 7 b. The vertical surface 30a is exposed to the blow-out port 7, and when the flap 8 is rotated in the diagonally downward direction, the vertical surface 30a is just opposed to the reinforcing plate 11a of the flap 8.

Therefore, as shown in fig. 10, when the flap 8 is rotated in the diagonally downward direction, the 2 nd side edge b in the back surface 8b of the flap 8 is located directly below the vertical surface 30 a.

According to embodiment 3, of the cold air blown out from the air outlet 7, the main flow of the cold air blown out along the longitudinal direction central portion of the air outlet 7 is, as shown by the arrows in fig. 10, in contact with the vertical surface 30a of the outer wall 7b, and the flow direction is vertical downward. Immediately below the vertical plane 30a is the downstream position of the 2 nd side edge b of the inner face 8b of the flap 8. Therefore, the main flow of the cold air flowing downward is guided by the vertical surface 30a, and flows obliquely downward along the inclined flap 8 after coming into contact with the back surface 8b of the flap 8 to become a downflow portion.

Therefore, the main flow of the cold air blown out from the air outlet 7 can be actively guided by the back surface 8b of the flap 8, and the blowing direction of the cold air can be effectively controlled by the flap 8.

[ 4 th example ]

Fig. 11 discloses and illustrates the 4 th embodiment. In embodiment 4, the flap 8B disclosed in FIG. 7 is used instead of the flap 8 of embodiment 3, and thus the range of use is different from that of embodiment 3. However, the configuration of the air outlet 7 in which the flap 8 is disposed is the same as that of embodiment 3.

In embodiment 4, the 2 nd side edge of the flap 8B has an upwardly standing wind direction guide 15. The cold air flows along the back surface 8B of the inclined flap 8B, becomes the downstream end of the flap 8B, and reaches the lower end 2 nd side edge of the flap 8B, and comes into contact with the wind direction guide 15.

As a result, the cold air flows obliquely downward from the air outlet 7 along the oblique direction of the flap 8, and the discharge angle becomes horizontal after coming into contact with the wind direction guide 15. Therefore, by enlarging the angle of the flap 8, the amount of cool air blown into the room can be effectively ensured, and the cool air can be made to flow in a substantially horizontal direction along the bottom surface of the ceiling panel a.

Thus, as in embodiment 3, the direction of the cold air blown out can be effectively controlled, and the flow feeling of the airflow can be alleviated.

[ example 5 ]

Fig. 12-14 disclose the 5 th embodiment. In embodiment 5, the internal structure of the air outlet 7 is different from that in embodiment 1, and the remaining structure is the same as that in the first embodiment. Embodiment 5 uses flap 8A as disclosed in fig. 6, but flap 8 as disclosed in fig. 3, flap 8B as disclosed in fig. 7, flap 8C as disclosed in fig. 8, and flap 8D as disclosed in fig. 9 may also be used. The shape of the flap is not particularly limited.

In embodiment 5, fig. 12 is a plan view of the decorative panel, with the flap omitted. Fig. 13 is a perspective view of the positional relationship between the decorative panel and the air outlet. Fig. 14 is a sectional view of the flow direction of the cold air blown out near the end face of the air outlet.

As shown in fig. 12 to 14, the module portions 40 are disposed at both ends in the longitudinal direction of the air outlet 7. The module 40 is disposed adjacent to the end face d of the air outlet 7 and along the width direction of the air outlet 7. The center portion of the thin block portion 40 has a recessed portion 41 to avoid the flap 8A. The closure 40 therefore does not interfere with the flap 8A and does not interfere with the rotation of the flap 8A.

Also, the module portion 40 does not protrude downward from the panel main body 5, but enters deep into the air outlet 7. The bottom surface 40a of the module 40 is perpendicular to the end surface d and is horizontal.

According to embodiment 5, the inner wall 7a and the outer wall 7b of the air outlet 7 extend downward from the air outlet 7, and approach the outer peripheral portion of the decorative panel 2, the air outlet is inclined, and the blown-out cool air is also inclined downward. In contrast, the end surface d of the air outlet 7 is vertically vertical, and a part of the cool air blown out from the air outlet 7 is vertically downward along the end surface d.

The end face d of the air outlet 7 is restricted by the corner cover 4c of the panel body 5, and the cold air vertically downward along the end face d is hardly diffused under the corner cover 4 c. In other words, the cool air of the lower surface of the corner cover 4c is less passed, and thus the frost formation of the lower surface of the corner cover 4c is likely to occur when the air conditioner 1 is in operation.

In the present embodiment, since the module portion 40 is disposed adjacent to the end face d of the air outlet 7, as shown in fig. 13 and 14, a part of the cold air blown out from the vicinity of the end face of the air outlet 7 contacts the module portion 40 and is blown out from the bottom face 40a of the module portion 40 in a substantially horizontal direction.

As a result, the cold air flows through the corner cover 4c due to the presence of the module portion 40, and frost formation of the corner cover 4c is prevented.

[ reference example ]

Fig. 15 to 17 disclose reference examples associated with the present invention.

Fig. 15 is a sectional view of the air conditioner, showing an enlarged outlet portion. FIG. 16 is a plan view of the flap and a side view of the flap of FIG. 17.

As indicated by white hollow arrows in fig. 15, the main body 1 exchanges heat with air by the heat exchanger N, and the air-cooled air that has been changed by the blower is discharged from the discharge port 7. As described above, the air outlet 7 is formed by the inner wall 7a and the outer wall 7b in the lower portion of the air outlet 7, and the air outlet 7 is inclined so as to approach the outer peripheral portion of the decorative panel 2, and the cold air is blown out obliquely downward from the air outlet 7 along the inner wall 7a and the outer wall 7 b.

The flap 8E disposed in the air outlet 7 guides the cold air blown out from the air outlet 7 in two directions. Specifically, the flap 8E is long in the longitudinal direction and extremely short in the width direction. The entire decorative surface 8a exposed to the inside of the room has no uneven shape. From this point of view, the same as the flap 8 of embodiment 1.

In the flap 8E of the reference example, a pair of support shafts 10a and 10b are further provided at both ends of the flap 8E, the support shafts being located on the extension line of the edge of the 1 st side surface, the support shafts being on the same axis. Meanwhile, the trim 8a of the flap 8E is curved so as to protrude downward at the center portion thereof in the width direction.

The inner surface 8b of the flap 8E includes a1 st wind direction guide 51, a 2 nd wind direction guide 52, and a 3 rd wind direction guide 53. The 1 st wind direction guide portion 51 is located at the intermediate portion 8E along the longitudinal direction of the flap 8E. The 1 st wind direction guide 51 includes a flat 1 st guide surface 51a for receiving the cold air blown out from the air outlet 7.

The 2 nd wind direction guide 52 is located at the 1 st end 8c of the flap 8E. The 2 nd air guide portion 52 includes a flat 2 nd guide surface 52a for receiving the cold air blown out from the air outlet 7. The 3 rd wind deflector 53 is located at the 2 nd end 8c of the flap 8E. The 3 rd air guide portion includes a flat 32 nd guide surface 53a for receiving the cold air blown out from the air outlet 7. The 2 nd guide surface 52a and the 3 rd guide surface 53a are curved along the decorative surface 8a in an arc shape.

The thickness of the 1 st wind direction guide 51 is greater than the thicknesses of the 2 nd wind direction guide 52 and the 3 rd wind direction guide 53. Therefore, level differences 54a and 54b are formed between the 1 st and 2 nd wind direction guides 51 and 52 and between the 1 st and 3 rd wind direction guides 51 and 53 in the thickness direction of the flap 8E.

As shown in fig. 15, the flap 8E is in a tilted state to guide the cold air of the outlet diagonally downward, and the 1 st guide surface 51a of the 1 st wind direction guide portion 51 is positioned above the 2 nd guide surface 52a of the 2 nd wind direction guide portion 52 and the 3 rd guide surface 53a of the 3 rd wind direction guide portion.

Therefore, the cold air guided by the 1 st guide surface 51a of the 1 st wind direction guide 51 is in the main flow direction, and the cold air guided by the 2 nd guide surface 52a of the 2 nd wind direction guide 52 and the 3 rd guide surface 53a of the 3 rd wind direction guide 53 flows below the main flow direction, and becomes the secondary flow direction.

That is, the cool air blown out from the central portion in the longitudinal direction of the air outlet 7 becomes the main flow, and the main flow is guided to the 1 st guide surface 51a of the flap 8E, so that the cool air of the air outlet 7 can be guided to the substantially horizontal direction, and the flow feeling can be reduced.

The cold air branches blown out from both ends in the longitudinal direction of the air outlet 7 are guided to the 2 nd guide surface 52a and the 3 rd guide surface 53a, and thus the cold air branches are diffused into the room. Thus, the occurrence of dust accumulation on the extension line of the diagonal line e of the decorative panel 2 can be effectively suppressed.

As shown in fig. 16, when the lengths of the 2 nd wind direction guide 52 and the 3 rd wind direction guide 53 in the longitudinal direction are f, the center line g passes through the middle of the 1 st wind direction guide 51 in the longitudinal direction, and the lengths L of the center line g to the 2 nd wind direction guide 52 and the length L of the bottom 3 wind direction guide 53 are preferably L ≧ 1.5 xf.

From various experimental results, if the length f and the length L comply with the above-described regulations, the amount of cold air guided in the substantially horizontal direction by the 1 st wind direction guide portion 51 of the flap 8E can be effectively ensured. At the same time, the amount of cold air guided in the diagonally downward direction by the 2 nd wind direction guide portion 52 and the 3 rd wind direction guide portion 53 of the flap 8E can be effectively reduced.

As shown in fig. 17, the angle of the 1 st guide surface 51a of the 1 st wind direction guide 51 is preferably 5 degrees upward with reference to the 2 nd guide surface 52a of the 2 nd wind direction guide 52.

As a result of various experiments, it was found that the 1 st guide surface 51a is 5 degrees higher than the 2 nd guide surface 52a, and thus the amount of cold air guided in the substantially horizontal direction by the 1 st guide surface 51a of the 1 st wind direction guide 51 can be effectively ensured. At the same time, the collision between the cold air guided by the 1 st guide surface 51a and the cold air guided by the 2 nd guide surface 52a and the 3 rd guide surface 53a can be suppressed to the minimum.

On the other hand, according to the above-described embodiment 1, when the flap 8 completely closes the air outlet, the decorative surface 8a of the flap 8 and the bottom surface of the panel main body 5 are located on the same horizontal plane. In contrast, in the flap 8E of the reference example, the support shafts 10a and 10b support the flap 8E when the flap rotates along the extension line of the 1 st side edge a. Therefore, when the flap 8E completely closes the air outlet 7, a portion of the trim 8a of the flap 8E, which is generally along the width direction of the flap 8E from the 1 st side edge a, is located on the bottom surface of the panel main body 5, and the remaining portion of the trim 8a enters the inside of the air outlet 7.

In this case, similar to the flap 8 of embodiment 1, the 1 st end 8c and the 2 nd end 8d of the flap 8E form support walls 9a and 9b, and support shafts 10a and 10b are disposed on the outer side surfaces of the support walls 9a and 9b, respectively, so that the flap 8E can be formed into an elongated plate-like structure without bending.

Then, when the flap 8E completely closes the air outlet 7, the decorative surface 8a of the flap 8E and the floor surface of the panel main body 5 are located on the same horizontal plane.

Several embodiments are described above, which are distance descriptions and do not show the scope of use of the embodiments. These novel embodiments may be used in other embodiments and may be omitted, substituted or modified without departing from the principles of the present invention. These embodiments and their modifications include the claims and objects of the invention, and also include the scope of the claims of the invention.
