The sucked air is blown out to the outer peripheral side by the impeller 52, reaches the heat exchanger 6, is cooled or heated in the heat exchanger 6, and then enters the air-conditioning room from the blowout ports 35a to 35d through the blowout flow path 2b. It is blown out. In this way, cooling or heating in the air-conditioned room is performed.

(Opening and closing operation by the opening and closing mechanism of the split decorative panel)
-Stop state-
In the stopped state of the air conditioner 1, as shown in FIGS. 1, 4, and 8 (a), each of the divided panels 41 a to 41 d is disposed at a position that covers and closes the suction port 34 of the casing 3. . In this stopped state, each of the divided panels 41a to 41d of the divided decorative panel 4 is located at substantially the same height in plan view, and the four substantially planar divided panels 41a to 41d are located at substantially the same height. It is adjusted to. For this reason, when it sees from the room | chamber interior, the division | segmentation decorative panel 4 is in the state which can mainly be seen. For this reason, in the stop state, since the suction port 34 is in a flat state that is not easily noticeable, the design is improved by making the air conditioner 1 appear clear to the user in the room. Thereby, the whole indoor ceiling surface can be refreshed.

-Operating state-
In the operating state of the air conditioner 1, as shown in FIGS. 4, 7, and 8B, the first divided panel 41a, the second divided panel 41b, the third divided panel 41c, and the fourth divided panel 4 are provided. The division panel 41d and the casing 3 are arranged apart from each other. Thereby, the suction to the inside of the casing 3 through the suction port 34 is possible, and the blowout through the blowout ports 35a to 35d is possible.

In addition, each division panel 41a-d is maintaining the state which became the positional relationship which overlapped with the blower outlets 35a-d in planar view also in the driving | running state through the case of a stop state. Thereby, the design is improved in that the air outlets 35a to 35d are not seen in a plan view not only in the stopped state but also in the operating state.
Further, in this operation state, each of the divided panels 41a to 41d is inclined with respect to the outlets 35a to 35d of the casing 3 by the angle adjusting mechanism 44, and the outlet direction is adjusted to a direction along the ceiling surface. Round flow can be realized. Thus, when it is set as a round flow, it can prevent that the wind which blows off through blower outlets 35a-d hits directly with respect to the user who exists in a room, and can reduce a draft feeling.

In addition, as shown in FIG.8 (b), in connection with making each division | segmentation panel 41a-d incline with respect to the casing 3, and implement | achieving a round flow via blower outlets 35a-d, in the suction inlet 34. Each divided panel 41a-d can be made to guide air so that the suction of air becomes easy.
-Transition from stop to operation-
The transition from the stop state to the operation state of the air conditioner 1 is a transition from the stop state shown in FIG. 8A to the operation state shown in FIG. 8B, and the open / close movable mechanism 43 is moved to each support member 42a. -D and each of the divided panels 41a-d are moved relative to the casing 3. Simultaneously with this operation, the open / close movable mechanism 43 moves the divided panels 41a to 41d apart from each other.

When each of the divided panels 41a to 41d moves, or while moving, the angle adjustment mechanism 44 functions, so that each of the divided panels 41a to 41d is in a stopped state and the outside in the direction in which each of the divided panels has moved downwards. Inclined with respect to the casing 3 so that the inside is upward.
And when each division | segmentation panel 41a-d moves and it will be in the inclined state, in order to control the blowing direction from each blower outlet 35a-d, the angle of each flap 45a-d is adjusted. Here, the flap 45 existing inside the casing 3 in the stopped state is in a state in which each of the divided panels 41a to 41d is in an operating state as each of the divided panels 41a to 41d is moved by the opening / closing movable mechanism 43. And the casing 3. And the direction to which the blowing air which passes between each division | segmentation panel 41 and the casing 3 heads is adjusted.

(Characteristics of the air conditioner of the first embodiment)
(1)
Conventionally, the air inlet of an air conditioner installed in a room or the like is always exposed to ensure air intake through the air inlet, and has become conspicuous when viewed from a user in the room. .
In contrast, in the ceiling-mounted air conditioner 1 of the first embodiment, in the stopped state, the divided panel 41 not only overlaps with the air outlets 35a to 35d in a plan view, but also covers the air inlet 34. It is closed. For this reason, when it sees from the room | chamber interior, a division | segmentation makeup | decoration control panel will be seen, and the suction inlet 34 is not conspicuous. Moreover, the surface of the division | segmentation decorative panel 4 becomes a flat shape, and is arrange | positioned in a substantially planar shape, when covering and sealing the suction inlet 34 in a stop state. For this reason, the part which is visible to the user existing in the air conditioning target space has a flat shape. Accordingly, the appearance is refreshed and the design is improved.

  Further, the open / close movable mechanism 43 moves from the peripheral state of each of the divided panels 41a to 41d to switch from the stop state where the suction port 34 is closed to the open operation state to ensure ventilation. Yes. Further, in the operating state, the split decorative panel 4 is widened by the open / close movable mechanism 43 as compared with the case where the distance between the split panels 41 and the distance from the air outlets 35a to 35d are stopped. For this reason, the ventilation resistance around suction inlet 34 and blower outlets 35a-d is reduced, and the suction of air via suction inlet 34 and the blowout of air via blower outlets 35a-d are made more efficient. .

With the above configuration, it is possible to improve the design when the air-conditioning apparatus 1 in the stopped state is viewed from the indoor side, and to sufficiently ensure the ventilation state in the handling state.
Moreover, the division | segmentation decorative panel 4 is opening the suction inlet 34 by moving the panel divided | segmented into four of the 1st-4th division | segmentation panels 41a-d. For this reason, when trying to open the suction port 34 to the same extent with one panel and the panel divided into four, it is divided into four as compared with the case where there is one panel. The panel can reduce the amount of movement required per sheet. Thereby, the movement amount of each division | segmentation panel 41a-d is required, and the deterioration of the design property by destroying an external appearance is suppressed, and the ventilation | gas_flowing state is ensured efficiently.

The open / close movable mechanism 43 is moved in its entirety including the peripheral edge of each of the divided panels 41a to 41d, and one end of each of the divided panels 41a to 41d is fixed to the casing 3. It has not been done. For this reason, in the operation state, the ventilation resistance in the vicinity of the suction port 34 is efficiently reduced, and a good suction state can be obtained.
(2)
In the ceiling-mounted air conditioner 1 according to the first embodiment, in the operating state, the divided decorative panel 4 is moved by the open / close movable mechanism 43 so as to maintain the state of covering the outlets 35a to 35d in plan view. is doing. For this reason, the divided decorative panel 4 hides the air outlets 35a to 35d in the operating state. Thereby, the blower outlets 35a-d are hidden, and the designability in an operating state can be improved.

(3)
As shown in FIG. 8, the split decorative panel 4 of the ceiling-mounted air conditioner 1 according to the first embodiment is blown from the casing 3 by the angle adjustment mechanism 44 in an operating state in which the suction port 34 is moved to the opening position. By adjusting the angle with respect to the outlets 35a to 35d, the air flow blown into the room from each of the outlets 35a to 35d can be adjusted. Further, each of the divided panels 41a to 41d of the divided decorative panel 4 is provided with flaps 45a to d, and the direction of the air flow passing through the outlets 35a to 35d can be adjusted by the flap 45. it can.

  Thereby, not only the direction of the air flow from the outlets 35a to 35d is adjusted depending on the position where the divided decorative panel 4 is present, but further, by changing the inclined state of the flaps 45a to 45d, the ventilation direction can be made finer. Can be adjusted. Further, even when a round flow is realized by setting the blown air flow along the ceiling surface by the angle adjusting mechanism 44, as shown in FIG. 8, the blowout direction can be adjusted by finely adjusting the blowing direction using the flaps 45 a to 45 d. It is possible to prevent the ceiling surface from being contaminated by avoiding that air is directed directly toward the ceiling surface.

(Modification of the air conditioner of the first embodiment)
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to Embodiment, A various change is possible in the range which does not deviate from the summary of invention.
(A)
In the air conditioning apparatus 1 of the first embodiment, the case where the divided decorative panel 4 is configured by four panels of the first to fourth divided panels 41a to 41d has been described as an example.

  However, the present invention is not limited to this, and the divided decorative panel 4 includes, for example, two divided panels, a first divided panel 141a and a second divided panel 141b, as shown in FIG. It may be. Even in this case, the suction port 34 is covered and closed in the stop state as shown in FIG. 9 (a), and the suction port 34 is opened in the operation state as shown in FIG. 9 (b). By blowing out from the two directions of the outlets 135a and 135b, the ventilation can be secured while improving the design as in the first embodiment by securing the ventilation.

(B)
In the air conditioning apparatus 1 of the first embodiment, the divided decorative panel 4 has the angle adjustment mechanism 44 so that the direction of the air flow blown out through the blowout ports 35a to 35d can be adjusted. ing.
However, the present invention is not limited to this, and as shown in FIG. 10, the divided decorative panel 4 does not particularly have the angle adjustment mechanism 44 described in the first embodiment, and the casing 3 It may be configured such that the angle is maintained in the split panel 41 with respect to. In this case, since the flat shape on the ceiling surface can be maintained from the stopped state through the operating state, the design can be improved from this point.

(C)
The air conditioner 1 according to the first embodiment is an example of a configuration that includes a flap 45 that is present inside the casing 3 in a stopped state and that appears between the divided panel 41 and the casing 3 when in an operating state. And explained.
However, the present invention is not limited to this, and a configuration in which the flap 45 referred to in the first embodiment is not provided as shown in FIG. For example, as shown in FIG. 11, the direction of the air flow from the air outlets 35 a to 35 d may be adjusted only by the angle adjusting mechanism 44.

  In addition to this, as shown in FIG. 12, each of the flaps 145a to 145d is arranged at a position almost in contact with the split panel 41 in the stopped state, and between the split panel 41 and the casing 3 in the operating state. You may make it appear in. In this case, unlike the case of the first embodiment, the air that has passed through the outlets 35a to 35d passes between the casing 3 and the flaps 145a to 145d, and the inclination of the flaps 145a to 145d is increased. The blowing direction can be adjusted by adjusting the degree.

(D)
In the air conditioning apparatus 1 according to the first embodiment, heat exchange is performed between the air sucked through the heat exchanger 6 provided inside the casing 3 and the refrigerant, and the conditioned air is indoors. The case of supplying is described as an example.
However, the present invention is not limited to this, and as shown in FIG. 13, when there are a plurality of outlets 35 a to 35 d, air blown from the outlets 35 a to 35 d is a target for heat exchange. You may comprise so that the temperature of a refrigerant | coolant may differ.

  For example, as shown in FIG. 13, the temperature of the refrigerant flowing through the heat exchanger 6a located in the vicinity of the air outlet 35 is set low so that the air blown from the air outlet 35a is cooled, and the air is blown out from the other air outlet 35c. The temperature of the refrigerant flowing through the heat exchanger 6c located in the vicinity of the blower outlet 35c may be set high so that the air that is blown becomes warmer than the air blown from the blower outlet 35a. In this case, when there are a plurality of outlets 35a to 35d, it becomes possible to adjust the outlet temperature according to the preference of the user who is in the direction of being blown out through the outlets 35a to 35d. It is possible to provide air having different desired temperatures.

  Further, as shown in FIGS. 14A to 14D, drain water generated around one of the refrigerant pipes while adjusting the temperature of the refrigerant flowing at different positions of the refrigerant pipes of the heat exchanger 6 to be different. It is good also as a structure further provided with the drain water guide 66 for guide | inducing to the refrigerant | coolant piping from which the other refrigerant | coolant temperature differs. The arrangement of the heat exchanger 6 in this case is not particularly limited, and the drain water guide 66 is a refrigerant pipe that can use the drain water generated from the portion where the drain water is generated for heat recovery. It is only necessary to have a structure that can lead to a part.

  For example, as shown to Fig.14 (a), the heat exchanger 6a-d further provided with the heat exchanger e arrange | positioned just above the suction inlet 34 corresponding to the blower outlets 35a-d is provided. The drain water generated from the heat exchanger 6c that is provided and inclined in the casing 3 is collected by the drain water guide 66 and is supplied to the heat exchanger 6a that is inclined in the casing 3. The heat may be recovered in the heat exchanger 6a.

  Moreover, as shown in FIG.14 (b), the structure which does not have the heat exchanger 6e mentioned above may be sufficient, and as shown in FIG.14 (c), the heat exchanger 6 inclines in the casing 3 inside. Instead, as shown in FIG. 14 (d), the heat exchangers 6 a and 6 c may be arranged apart from each other inside the casing 3 and connected via a drain water guide 66. Thus, in the case where the temperature of the refrigerant flowing through the refrigerant pipe is different in order to change the temperature of the air blown through the air outlets 35a to 35d of the casing 3, the generated drain water is used, The heat recovery operation can be performed by the drain water guide 66, and the thermal efficiency of the air conditioner 1 can be improved.

<Other embodiments>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention.
(A)
The present invention is not limited to the ceiling-mounted air conditioner 1, 200, 300 in the first to third embodiments described above, and is, for example, a ceiling-mounted air conditioner 400 as shown in FIG. May be. In addition, about this ceiling installation type air conditioning apparatus 400, the point which is common in the air conditioning apparatus 1 of 1st Embodiment is abbreviate | omitted here.

The division | segmentation decorative panel 4 of the air conditioning apparatus 400 has the 1st-4th division | segmentation panels 441a-441d, as shown in FIG. Each of the divided panels 441a to 441d has a rotation opening / closing movable mechanism 444a to 444d, and the rotation state differs depending on whether the air conditioner 400 is in a stopped state or an operating state. Adjusted as follows.
In the stop state, as shown in FIG. 22A, the air conditioner 400 has the first to fourth divided panels 441 a to 441 d of the casing 3 at the periphery of the casing 3 arranged on the ceiling surface in plan view. They are arranged in a substantially planar shape along the lower surface.

Further, in the operating state, as shown in FIG. 22B, the air conditioner 400 rotates the first to fourth divided panels 441 a to 441 d by the respective rotary opening / closing movable mechanisms 444 a to d to Suction ports 434a to 434d appear on the inside of the lower surface. At the same time, the air outlets 435a to 435d appear on the outside of the lower surface of the casing 3, respectively.
In this operating state, when the blower fan 5 is driven, the indoor air sucked into the casing 3 through the suction ports 434a to 434d passes through the suction grill 36, dust is removed by the filter 37, and heat exchange is performed. The temperature is adjusted by heat exchange with the refrigerant flowing through the vessel 6 and blown out into the room through the respective outlets 435a to 435d.

  As described above, in the air conditioner 400, the inlets 434a to 434d and the outlets 435a to 435d are secured only by rotating the divided panels 441a to 441d by the rotary opening / closing movable mechanisms 444a to 443d. As with the air conditioners 1, 200 and 300 of the first to third embodiments, it is possible to easily ensure ventilation for air conditioning while improving the design so that the ceiling surface can be clearly seen. .

(B)
Moreover, the ceiling-installation-type air conditioning apparatus 500 as shown in FIG. 23 and FIG. 24 may be sufficient. In addition, about this ceiling installation type air conditioning apparatus 500, about the point which is common in the air conditioning apparatus 1 of 1st Embodiment, description is abbreviate | omitted here.
As shown in FIG. 23, the fitting decorative panel 504 of the air conditioning apparatus 500 is provided with blocking members 39 a to 39 f in the casing 3 for partially blocking ventilation through the suction port 534. As shown in FIG. 23, the blocking members 39a to 39f are members (members extending in the depth direction of the paper surface in FIG. 23) extending in parallel with each other so as to partially block the ventilation of the suction port 534. Since the blocking members 39s to 39e are provided at the suction port 534, during operation, the indoor air passes through the suction ports 534a to 534e and is taken into the casing 3 so as to avoid the blocking members 39a to 39e. . Further, as shown in FIG. 23, the fitting decorative panel 504 is provided with blocking corresponding openings 49a to 49f so as to correspond to the blocking members 39a to 39f of the casing 3, and between the blocking corresponding openings 49a to 49f. A plurality of fitting members 541a to 541e extending in parallel with each other are provided so as to correspond to the ventilation portions of the suction ports 534a to 534e.

  When the air conditioning apparatus 500 is in a stopped state, as shown in FIG. 24A, the fitting members 541a to 541e of the fitting decorative panel 504 are respectively cut-off members 39a to 39f of the casing 3. Are fitted to each other to block the ventilation, and a substantially flat surface is constituted by the lower end surfaces of the respective fitting members 541a to 541e and the lower end surfaces of the respective blocking members 39a to 39f. Thereby, in the stop state, when the ceiling surface is viewed from the indoor side, the lower surface of the air conditioner 500 can be clearly seen. Further, when the air conditioner 500 is in an operating state, as shown in FIG. 24 (b), the fitting members 541a to 541e of the fitting decorative panel 504 are operated by the opening / closing movable mechanism 543. Thus, the casing 3 is lowered with respect to the casing 3. Thereby, in the operating state, when the blower fan 5 is driven, the indoor air passes through the blocking corresponding openings 49a to 49f as shown in FIG. 24B, and further, the suction ports 534a to 534e. Is taken into the casing 3. The air taken in this way passes through the suction grille 36, dust is removed by the filter 37, the temperature is adjusted by heat exchange with the refrigerant flowing through the heat exchanger 6, and the air outlets 535a to 535d are passed through. Then, it is blown out into the room again.

  As described above, the air conditioner 500 can improve the design so that the ceiling surface can be clearly seen, similarly to the air conditioners 1, 200, and 300 of the first to third embodiments described above. In addition, the intake of room air in the operation state is not the intake through the horizontal gap formed by the separation distance between the fitting decorative panel 4 and the casing 3, but when the operation state is changed from the stop state. This is performed through a flow path that is caused by a positional shift between the positions of the suction ports 534a to 534e and the positions of the blocking corresponding openings 49a to 49f. Thereby, in order to ensure the intake of the indoor air into the casing 3, it is sufficient if the positional relationship between the positions of the suction ports 534a to 534e and the positions of the shut-off corresponding openings 49a to 49f can be ensured. There is no need to separate the fitting decorative panel 504 from the casing 3 more than necessary. As a result, the degree of lowering of the fitting decorative panel 504 in the operating state can be reduced, and ventilation can be ensured. In addition, since the degree of lowering of the fitting decorative panel 504 is suppressed, the fitting decorative panel 504 is lowered from the ceiling, thereby suppressing problems such as a feeling of pressure that a person in the room feels that the ceiling is lowered. In this respect, the design can be improved.

  According to the present invention, since ventilation can be ensured while improving design properties, application to an air conditioner that is arranged at a position often seen by a user and requires design properties is particularly useful.
