(Air conditioning operation of air conditioner)

Next, the air conditioning operation of the air conditioner 1 will be described with reference to FIGS. 1 and 2. Here, as described above, the state of the air conditioner 1 is largely divided into the stopped state and the operating state. Separated.

[0042] In the operation state, in a stopped state, each of the divided panels 41a to 41d is arranged at a position covering the suction port 34, and is moved by the open / close movable mechanism 43, and the suction port 34 and the outlets 35a to 35d are moved. Force S is opened. When each of the divided panels 41a to 41d is disposed at the operating position, the fan motor 51 is driven and the impeller 52 of the blower fan 5 is rotated. In addition, as the fan motor 51 is driven, refrigerant is supplied into the heat exchanger 6 from an outdoor unit (not shown). Here, the heat exchanger 6 acts as an evaporator during the cooling operation and as a condenser during the heating operation. As the impeller 52 rotates, the air in the air-conditioned room is also sucked into the casing 3 through the suction passage 2a. The sucked air is blown out to the outer peripheral side by the impeller 52, reaches the heat exchanger 6, and is cooled or heated in the heat exchanger 6, and then enters the air-conditioning room from the blowout openings 35a to 35d through the blowout flow path 2b. It is blown out with force. In this way, cooling or heating in the air-conditioned room is performed.

[0043] (Opening / closing operation by opening / closing mechanism of divided decorative panel)

State of standstill

In the stopped state of the air conditioner 1, as shown in FIGS. 1, 4, and 8 (a), each of the divided panels 41a to 41d is disposed at a position that covers and closes the suction port 34 of the casing 3. Yes. In this stopped state, each of the divided panels 41a to 41d of the divided decorative panel 4 is positioned at substantially the same height in plan view, and the four divided panels 4la to 4d having substantially planar shapes are positioned at substantially the same height. It is adjusted as follows. For this reason, when viewed from the room, the split makeup panel 4 is mainly visible. For this reason, in the stop state, since the suction port 34 is inconspicuous and flat, the air conditioner 1 is clearly seen from the user in the room, so that the design is improved. As a result, the entire indoor ceiling surface Can be refreshed.

[0044] Operating state

In the operating state of the air conditioner 1, as shown in FIGS. 4, 7, and 8 (b), the first divided panel 41a, the second divided panel 41b, the third divided panel 41c, and the fourth divided panel 4 are divided. The dividing panel 41d and the casing 3 are arranged apart from each other. As a result, the suction into the casing 3 through the suction port 34 is possible, and the blowout through the blowout ports 35a to 35d is possible.

Note that each of the divided panels 41a to 41d maintains a positional relationship that overlaps with the air outlets 35a to 35d in a plan view even in the operating state through the case of the stopped state. As a result, the air outlets 35a to 35d improve the design characteristics in terms of the flaws that are visible in plan view, not only in the stopped state but also in the operating state.

[0045] 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 so that the blowing direction is along the ceiling surface. Round flow adjusted in the direction can be realized. In this way, when the round flow is used, it is possible to prevent the wind blown through the outlets 35a to 35d from directly hitting the user in the room and reduce the draft feeling.

In addition, as shown in FIG. 8 (b), each of the divided panels 41a to 41d is inclined with respect to the casing 3 to realize a round flow through the outlets 35a to 35d. Each of the divided panels 4 la to d allows air to be guided so that the air can be easily sucked in.

Transition from stop to operation

Stop state force of the air conditioner 1 The transition to the operation state is a transition from the stop state shown in FIG. 8 (a) to the operation state shown in FIG. 8 (b). 42a to d and the respective divided panels 41a to 41d are moved with respect 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.

[0046] When each of the divided panels 41a to 41d moves or while moving, the angle adjusting mechanism 44 functions, so that each of the divided panels 41a to 41d moves in a stopped state. It is inclined with respect to the casing 3 so that the outer side in the moved direction is downward and the inner side 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 brought into operation when the divided panels 41a to d are moved by the opening / closing movable mechanism 43. Appears between d and casing 3. Then, the direction in which the blown air passing between each divided panel 41 and the casing 3 is directed is adjusted.

(Characteristics of the air conditioner of the first embodiment)

(1)

Conventionally, the air inlet of an air conditioner installed indoors is always exposed to ensure air intake through the air inlet, and it is conspicuous when looking at the user's power in the room. Yes.

On the other hand, 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 the air inlet 34 It is closed and covered. For this reason, when viewed from inside the room, the split makeup panel is visible, and the suction port 34 is inconspicuous. Further, the surface of the divided decorative panel 4 has a flat shape, and is arranged in a substantially planar shape when covering and closing the suction port 34 in a stopped state. For this reason, the portion that can be seen by the user in the air-conditioning target space has a flat shape. Therefore, the appearance is refreshed and the design is improved.

In addition, the open / close movable mechanism 43 moves the position of the peripheral portion of each of the divided panels 41a to 41d to switch from the stopped state where the suction port 34 is closed to the opened operating state to ensure ventilation. Yes. Furthermore, the divided decorative panel 4 is expanded in the operating state by the open / close movable mechanism 43 as compared with the case where the distance between the divided panels 41 and the distance from the air outlets 35a to 35d is stopped. For this reason, the airflow resistance around the suction port 34 and the air outlets 35a to 35d is reduced, and the air suction through the air inlet 34 and the air blowing through the air outlets 35a to 35d are made more efficient. . [0048] With the configuration described above, it is possible to improve the design when the air conditioner 1 in the stopped state is viewed from the indoor side force, and to sufficiently ensure the ventilation state in the handling state.

Further, the divided decorative panel 4 opens the suction port 34 by moving the panel divided into four of the first to fourth divided panels 41a to 41d. 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 compared to the case with one panel. The panel that is used can reduce the required amount of movement per sheet. As a result, a large amount of movement of each of the divided panels 41a to 41d is required, and the poor design due to the deterioration of the external appearance is suppressed, and the ventilation state is efficiently secured.

The open / close movable mechanism 43 is moved as a whole, including the peripheral portion of each of the divided panels 41a to 41d, and one end of each of the divided panels 41a to 41d is relative to the casing 3. It is not fixed. For this reason, in the operating state, the ventilation resistance in the vicinity of the suction port 34 is efficiently reduced, and a good suction state can be obtained.

[0049] (2)

In the ceiling-mounted air conditioner 1 of the first embodiment, in the operating state, the split decorative panel 4 is moved by the open / close movable mechanism 43 so as to cover the air outlets 35a to 35d in plan view. Is maintained. For this reason, the division | segmentation decorative panel 4 has concealed the blower outlets 35a-d in the driving | running state. Thereby, the blower outlets 35a-d are hidden, and the design property 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 by the angle adjusting mechanism 44 in the 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. Furthermore, each of the divided panels 41a-d of the divided decorative panel 4 is provided with flaps 45a-d, and the direction of the air flow passing through the outlets 35a-d can also be adjusted by the flaps 45. it can. [0050] Thereby, the air flow direction from the air outlets 35a to 35d is adjusted not only by the position where the divided decorative panel 4 is present, but also the air flow direction is changed by changing the inclined state of the flaps 45a to 45d. You can adjust more finely. In addition, even when round flow is realized with the air flow direction along the ceiling surface by the angle adjustment mechanism 44, as shown in Fig. 8, by finely adjusting the air blowing direction by the flaps 45a to d. In addition, it is possible to prevent contamination of the ceiling surface by avoiding that the blown air is directed directly against the ceiling surface.

(Modification of the air conditioner of the first embodiment)

Although one embodiment of the present invention has been described above, the present invention is not limited to the embodiment, and various modifications can be made without departing from the gist of the invention.

(A)

In the air conditioner 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 has two divided panel forces, for example, a first divided panel 141a and a second divided panel 141b as shown in FIG. It may be configured. Even in this case, as shown in Fig. 9 (a), V is stopped and covers the suction port 34 and closed, and as shown in Fig. 9 (b)! By ensuring the ventilation by opening the suction port 34 and blowing out the two-way forces of the outlets 135a and 135b, it is possible to ensure the ventilation while improving the design as in the first embodiment.

(B)

In the air conditioner 1 of the first embodiment, the divided decorative panel 4 has the angle adjusting mechanism 44 so that the direction of the air flow blown out through the outlets 35a to 35d can be adjusted. ing.

However, the present invention is not limited to this, 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 A configuration in which the angle is maintained in the divided panel 41 with respect to the case 3 may be adopted. In this case, since the flat shape on the ceiling surface can be maintained from the stopped state through the operating state, this point power can also improve the design. (c)

The air conditioner 1 according to the first embodiment described above has a configuration that includes a flap 45 that exists inside the casing 3 in a stopped state and appears between the divided panel 41 and the casing 3 when the air conditioner 1 is in an operating state. Explained with an example.

However, the present invention is not limited to this, and a configuration in which the flap 45 described in the first embodiment is not provided may be employed as shown in FIG. For example, as shown in FIG. 11, the direction of the air flow from the air outlets 35a to 35d is 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 dividing panel 41 in the stopped state, and in the operating state! It may be allowed to appear between the channel 41 and the casing 3. 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 d, and the inclination of the flaps 145a to d is increased. The blowing direction can be adjusted by adjusting the degree of.

(D)

In the air conditioner 1 of the first embodiment, the air that has just been sucked in through the heat exchange 6 provided inside the casing 3 and exchanges heat between the air and the refrigerant is conditioned air. If you supply it indoors, please explain it 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 35a to 35d, the air blown from the outlets 35a to 35d exchanges heat. It may be configured to change the temperature of the refrigerant to be performed.

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 out 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 in the direction of blowing through the outlets 35a to 35d. Can provide air of different desired temperature It becomes pretty.

[0055] Further, as shown in FIGS. 14 (a) to (d), while adjusting the temperature of the refrigerant flowing at different positions of the refrigerant pipe of the heat exchanger 6 to be different, V and the deviation of one of the refrigerant pipes are adjusted. A drain water guide 66 for guiding the drain water generated in the vicinity to the refrigerant pipe having the other refrigerant temperature may be further provided. The arrangement of the heat exchanger 6 in this case is not particularly limited. Also, the drain water guide 66 has a partial force that generates drain water, and the portion of the refrigerant pipe that can use the generated drain water for heat recovery. It is sufficient if the structure can lead to

For example, as shown in FIG. 14 (a), further comprising a heat exchange _e which is located directly above the suction port 34, provided with a heat exchange 6 _a to d provided corresponding to the air outlet 35a~d Drain water generated from the heat exchange ^ 6c is inclined inside the casing 3 and collected by the drain water guide 66, and the heat exchange arranged in the casing 3 is inclined. Let's introduce V to ^^ 6a, and heat recovery ^^ 6a to recover heat.

[0056] As shown in Fig. 14 (b), the heat exchange ^ 6e described above may be omitted, and as shown in Fig. 14 (c), the heat exchanger 6 is As shown in FIG. 14 (d), the heat exchangers 6a and 6c may be arranged apart from each other inside the casing 3 and connected via a drain water guide 66. . In this way, when the temperature of the refrigerant flowing through the refrigerant pipe is different in order to change the temperature of the air blown through the 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.

Hereinafter, a ceiling-mounted air conditioning apparatus 200 according to a second embodiment of the present invention will be described with reference to FIGS.

[0057] Note that, with respect to the ceiling-mounted air conditioner 200 of the second embodiment, the points that are common to the air conditioner 1 of the first embodiment are not described here.

The divided decorative panel 4 of the air conditioner 200 includes first to fourth divided panels 241a to d arranged below the suction grill 36, and each of the divided panels 241a to 241d is a folding opening / closing movable mechanism. 243a to d are the same as the air conditioner 1 of the first embodiment. Is also different.

As shown in FIGS. 15 (b) and 16 (a) to (e) (partially enlarged sectional view of the portion indicated by “P” in FIG. 15 (a)), the folding opening / closing movable mechanisms 243a to d On the substantially same plane, the folding opening / closing movable mechanism 243 is arranged so that the folding axis directions thereof are parallel to each other.

Further, the folding open / close movable mechanisms 243a to 243d are provided so as to extend in the longitudinal direction in the vicinity of the center of the divided panels 241a to 241d. The folding open / close movable mechanisms 243a to d fold the divided panels 241a to 241d with the longitudinal direction as the axial direction.

Here, the folding opening / closing movable mechanisms 243a to 243d function as fixed ends where the positions of those that can rotate with respect to the casing 3 are fixed. Further, as shown in FIG. 16, both end portions of each of the divided panels 241a to 241d function as free ends that freely slide with respect to the panel frame 33 provided with the slide space S.

In the stopped state, as shown in FIGS. 15 (a) and 16 (a), each of the divided panels 241a to 241d is accommodated in the slide space S provided in the panel frame 33 without being folded. The suction port 234 is covered by being arranged so as to be continuous with each other on substantially the same plane.

[0059] In the operation state, as shown in FIGS. 15 (b) and 16 (b) to (e), each of the split panels 241a to 241d is folded by the respective folding opening / closing movable mechanisms 243a to d. (Folding is shown in stages in Figs. 16 (b), (c), (d), and (e)). Then, each of the divided panels 241a to 241d maintains the state in which each of the folding opening / closing movable mechanisms 243a to d functioning as a fixed end is supported with respect to the casing 3. Then, the both end portions of each of the divided panels 241a to d functioning as free ends are slid so as to approach each other in the slide space S, so that each divided panel 241a to d is folded. It is. At this time, both ends of the panel frame 33 and the divided panels 241a to 241d are lowered with respect to the casing 3. In this way, the suction port 234 is opened.

Note that the air sucked from the suction port 234 is blown out through the respective outlets 235a to 235d generated between the lowered panel frame 33 and the casing 3.

(Features of the air conditioner of the second embodiment) In the ceiling-mounted air conditioner 200 of the second embodiment, the divided decorative panel 4 has folding and opening / closing movable mechanisms 243a to 243d. The folding opening / closing movable mechanisms 243a to 243d are folded so as to be positioned perpendicular to the suction port 34 when the divided panels 241a to 241d are changed from the stopped state to the operating state. As a result, the number of parts arranged so as to obstruct the air flow trying to pass through the suction port 34 is reduced compared to the stopped state.

Further, the length of the portion extending downward from the suction port 34 in the folded state can be shortened as compared with the case where each of the divided panels 241a to 241d is brought into the vertical state without being folded. This reduces ventilation resistance around the suction port 34 and facilitates suction from the surroundings.

[0061] Each folding opening / closing movable mechanism 243a-d is provided in each of the divided panels 241a-d divided into a plurality of parts, and each of the divided panels 241a-d is individually folded. For this reason, the number of draft resistances can be reduced compared to the case where one split panel is folded in two.

Furthermore, by folding each of the divided panels 241a to 241d instead of one, the length of the part extending downward from the suction port 34 in the folded state can be further shortened. Ventilation resistance is further reduced, making it easier to suck in ambient force.

In addition, the operation of each of the divided panels 241a to 241d required for shifting to the stop state force operation state is reduced, and the degree of protruding downward from the suction port 34 is suppressed to improve the design. ing.

(Modification of Air Conditioner of Second Embodiment)

(A)

In the air conditioner 200 of the second embodiment, the folding open / close movable mechanisms 243a to 243d function as fixed ends with respect to the casing 3, and both ends of the divided panels 241a to 241d are connected to the slide space S of the panel frame 33. For example, when it functions as a free end that slides I gave it as an explanation.

However, the present invention is not limited to this. For example, the same effect can be obtained with the configuration shown in FIG.

[0064] <Third Embodiment>

Hereinafter, a ceiling-mounted air conditioner 300 according to a third embodiment of the present invention will be described with reference to FIG. 19 and FIG.

Note that the description of the ceiling-mounted air conditioner 300 of the third embodiment that is common to the air conditioner 1 of the first embodiment is omitted here.

The divided decorative panel 4 of the air conditioner 300 includes first to fourth divided panels 34 la to f arranged below the suction grill 36, and each of the divided panels 341a to f slides. It is most different from the air conditioners 1 and 200 of the first and second embodiments in that it has opening / closing movable mechanisms 343a to f.

As shown in FIGS. 19 (a), 19 (b) and 20, this slide opening / closing movable mechanism 343a-f is a mechanism relating to both end portions of each divided panel 341a-f, and is one end of each divided panel 341a-f. A mechanism that functions as a fixed end that rotatably supports the part 3 with respect to the casing 3, and a free end that slides the other end of each of the divided panels 341a-f with respect to the slide space S provided in the panel frame 33 And a mechanism for

[0065] Note that the slide opening / closing movable mechanisms 343a to 343f are arranged so that their main slide directions (slide directions which are horizontal directions) are common to each other. Here, as shown in FIGS. 19 and 20, each divided panel 341a-c slides at the left end in the figure, and each divided panel 341d-f slides at the right end in the figure. Has been placed.

Here, in the stopped state, as shown in FIG. 19 (a), the divided panels 341a to f are accommodated in the slide space S provided in the panel frame 33 without being slid, and are substantially on the same plane. The suction port 334 is covered by being arranged so as to be continuous with each other.

In the operating state, as shown in FIG. 19 (b) and FIG. 20, each of the divided panels 341a to f operates so that each of the slide open / close movable mechanisms 343a to f functions so that each of the divided panels 341a to f has a suction port. One end slides with respect to the slide space S provided in the panel frame 33 so as to be in a vertical positional relationship with respect to 334. At this time, both end portions of the panel frame 33 and the divided panels 34 la to f are lowered with respect to the casing 3. In this way, the suction port 334 is opened.

[0066] Air sucked from the suction port 334 is blown out through the respective outlets 335a to 335d formed between the lowered panel frame 33 and the casing 3.

(Characteristics of the air conditioner of the third embodiment)

In the ceiling-mounted air conditioner 300 of the third embodiment, each of the divided panels 341a to f is in a direction substantially perpendicular to the suction port 334 when the slide opening / closing movable mechanisms 343a to f function in an operating state. Change the position so that it faces. For this reason, the portion of each of the divided panels 341a to ί arranged so as to be obstructed against the air flow trying to pass through the suction port 334 is smaller than that in the stopped state. Also, each slide opening / closing movable mechanism 343a-f functions as an end of each of the divided panels 341a-f divided into a plurality of parts, and slides each of the divided panels 341a-f individually. . For this reason, compared to the case where the single divided panel is slid to open the suction port 334, a plurality of the divided panels 341a to f are slid to open the suction port 334. Can be reduced.

[0067] Sarako, by sliding each of a plurality of divided panels 341a-f individually instead of one, the length of the portion extending downward from the suction port 334 in the slid state is further increased. The air flow resistance around the suction port 334 can be further reduced to further facilitate the suction of ambient force.

In addition, as a result, the operation of each of the divided panels 241a to 241f required for shifting to the stop state force operation state is reduced, and the degree of protruding downward from the suction port 334 is suppressed to improve the design. ing.

In addition, while the divided panels 341a, 31b, and 341c are arranged in parallel to each other, the divided panels 341d, 341e, and 341f are arranged in parallel to each other. Then, by opening and closing the slide opening / closing movable mechanisms 343a to 343f while maintaining these parallel states, the airflow resistance of the suction port 334 can be reduced even during the opening / closing operation. .

(Modification of the air conditioner of the third embodiment)

(A)

In the air conditioner 300 of the third embodiment, the case where the panel frame 33 is lowered while sliding with respect to each of the divided panels 341a to f in the operating state has been described as an example.

However, the present invention is not limited to this. For example, as shown in FIG. 21 (a), a nodal frame 33 may be provided! / ,! /.

(B)

Further, as shown in FIG. 21 (b), each split opening / closing mechanism having each slide opening / closing movable mechanism 343a-f is provided. The force of each of the channels 341a to f is provided in the slide space S provided in the panel frame 33, and there may be no portion functioning as a fixed end.

[0069] (C)

In addition, as shown in FIG. 21 (c), each of the divided panels 341a to f has a slide opening / closing movable mechanism 343a to f whose one end functions as a fixed end in the panel frame 33 and whose other end is a casing 3 It may be configured to function as a free end in the slide space S provided in.

(D)

In addition, as shown in FIG. 21 (d), one of the slide opening / closing movable mechanisms 343a to f that each of the divided panels 341a to f has functions as a fixed end in the casing 3 and the other end to the panel frame 33. It is configured to function as a free end in the provided slide space S, and the divided panels 341a to 341f do not have to be arranged in parallel with each other.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the 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. For example, the ceiling-mounted air conditioner 400 as shown in FIG. May be. Note that the description of the ceiling-mounted air conditioner 400 that is common to the air conditioner 1 of the first embodiment is omitted here. The split decorative panel 4 of the air conditioner 400 has first to fourth split panels 441a to 441d as shown in FIG. Each of the divided panels 441a to d has a rotation opening / closing movable mechanism 444a to d, and rotates depending on whether the air conditioner 400 is in a stopped state or in an operating state. The state is adjusted to be different.

[0071] In the stopped state, as shown in FIG. 22 (a), the air conditioner 400 has the first to fourth divided panels 441a to 441d force S of the casing 3 arranged on the ceiling surface in the plan view. Stay along the bottom edge of casing 3

RU Further, in the operating state, as shown in FIG. 22 (b), the air conditioner 400 has the first to fourth dividing panels 441a to d rotated by the respective rotary opening / closing movable mechanisms 444a to d, and Suction ports 434a to 434d appear on the inside of the lower surface of the single 3 respectively. At the same time, 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, and dust is removed by the filter 37, and heat is generated. The temperature is adjusted by heat exchange with the refrigerant flowing through the exchanger 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 d by the rotation opening / closing movable mechanisms 444a to d. 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. it can.

(B)

Further, a ceiling-installed type air conditioner 500 as shown in FIGS. 23 and 24 may be used. Note that the description of the ceiling-mounted air conditioner 500 that is common to the air conditioner 1 of the first embodiment is omitted here.

As shown in FIG. 23, in the fitting panel 504 of the air conditioner 500, the casing 3 is provided with blocking members 39a to 39f for partially blocking ventilation through the suction port 534. Yes. As shown in FIG. 23, the blocking members 39a to 39f are members extending in parallel to each other so as to partially block the ventilation of the suction port 534 (members extending in the depth direction of the paper surface in FIG. 23). . Since the shutoff members 39s to 39e are provided at the suction port 534, during operation, indoor air passes through the suction ports 534a to 534e and enters the casing 3 so as to avoid the shutoff members 39a to 39e. It is captured. 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. [0073] When the air conditioner 500 is in a stopped state, as shown in Fig. 24 (a), the force of each of the fitting members 541a to 541e of the fitting decorative panel 504 is the blocking member of the casing 3 It is fitted to 39a to 39f to block the ventilation, and a substantially flat surface is constituted by the lower end face of each fitting member 541a to 541e and the lower end face of each blocking member 39a to 39f. Yes. Thus, in the stopped 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. Thus, 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. 24 (b), and further, the suction port 534a to the suction port It passes through 534e and is taken into the casing 3. The air taken in this way passes through the suction grill 36, dust is removed by the filter 37, and the temperature is adjusted by heat exchange with the refrigerant flowing through the heat exchanger 6, and each of the outlets 535a to 535d The air is blown out again through the room.

[0074] As described above, in the air conditioner 500, like the air conditioners 1, 200, 300 of the first to third embodiments described above, the ceiling surface can be clearly seen to improve the design. Can do. In addition, when the indoor air is taken in during operation, the stop state force that is not the intake through the horizontal gap formed by the separation distance between the fitting decorative panel 4 and the casing 3 is also in the operational state. In addition, it is performed via 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. Thus, in order to secure 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 secured. Therefore, it is not necessary 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 suppressed, and ventilation can be ensured. In addition, since the lowering level of the fitting panel 504 is suppressed, the ceiling force is lowered, and the person in the room feels a feeling of pressure as if the ceiling is lowered. Etc., and the design can be improved in this respect as well. Industrial applicability

According to the present invention, it is possible to ensure ventilation while improving design properties, and therefore, it is particularly useful to be applied to an air conditioner that is arranged at a position often seen by a user and requires design properties.
