On the floor surface at the side of each bed 22, a cabinet 25 used for placing a television, a refrigerator, etc. and for storing small items is installed.

  An air-conditioning air supply unit 27 including an indoor heat exchange unit of the air conditioner 26 is disposed behind the ceiling of the hospital room 21. In the hospital room 21, an air-conditioning air outlet 28 is disposed in an extended state along the window 21c near the lower portion of the window 21c. In the back of the ceiling of the hospital room 21, between the air-conditioning air supply machine 27 and each hospital room console 24 and between the air-conditioning air supply machine 27 and the air outlet 28, each hospital room console 24 and air is supplied from the air-conditioning air supply machine 27. A plurality of blower pipes 29 for supplying conditioned air to the air outlet 28 are extended.

  As shown in FIGS. 2 and 3, the housing 31 constituting the supply duct constituting the outer shell of the hospital room console 24 has a vertically long duct shape with a pentagonal cross section. An end plate 31 a that closes the upper end of the housing 31 is provided with a connection portion 32 for connecting a blower pipe 29 from the air-conditioning air supply unit 27. The lower end of the housing 31 is closed by an end plate (not shown). At both upper and lower ends of the pair of inclined walls 31b facing the area on the bed 22 side on both sides of the housing 31, the air outlet 33 for cooling and the air outlet 34 for heating are respectively directed to the area on the foot side of the bed 22.

  On the upright walls 31c on both sides of the housing 31, a plurality of medical gas connection ports 35, a power outlet 36, a switch 37 for electric lights, etc., and a connector 40 for network connection are arranged. By using or operating these medical gas connection port 35, power outlet 36, switch 37 for electric light, etc. and connector 40 for network connection, medical gas can be supplied to the patient. The patient can use it for various electric devices, turn on and off the light, connect a personal computer and so on.

On the inner side surface of the housing 31, a gas supply pipe 38 connected to the medical gas connection port 35 and a harness 39 made of an electric wire, a data transmission cable, and the like are extended.
As shown in FIGS. 4 and 5, the outer frames 41 of the cooling outlet 33 and the heating outlet 34 are each formed in a rectangular frame shape having both front and rear surfaces opened. As shown in FIGS. 5 and 6, an opening frame 42 is fixed to the front surface of each outer frame 41, and a louver 53 including a plurality of blades 43 is attached in the opening frame 42. An opening / closing mechanism 44 as an opening / closing mechanism is disposed in the outer frame 41 behind the opening frame 42. That is, a fixed opening / closing plate 45 is installed between both side walls of the outer frame 41, and a plurality of elongated through holes 45 a extending in the vertical direction are formed in the fixed opening / closing plate 45. A first movable opening / closing plate 46 and a second movable opening / closing plate 47 are joined and disposed on both front and rear surfaces of the fixed opening / closing plate 45 so as to be movable in the left-right direction. A plurality of elongated holes 46a, 47a similar to 45a are formed.

  An operation lever 48 protrudes forward from the front upper portion of the first movable opening / closing plate 46. When the first movable opening / closing plate 46 is moved to one position by the operating lever 48, the through holes 46a of the first movable opening / closing plate 46 coincide with the through holes 45a of the fixed opening / closing plate 45, and The air-conditioning air flow path in the frame 41 can be opened. On the other hand, when the first movable opening / closing plate 46 is moved to the other position by the operation lever 48, the respective through holes 46a of the first movable opening / closing plate 46 are closed so as not to coincide with the respective through holes 45a of the fixed opening / closing plate 45. As a result, the air-conditioning air flow path in the outer frame 41 cannot be opened. Accordingly, the air outlets 33 and 34 are opened and closed by the first movable opening / closing plate 46.

  An operating body 49 is disposed in the outer frame 41 behind the second movable opening / closing plate 47 so as to be movable in the left-right direction via a support plate 50 and a stay (not shown). The operating body 49 is connected to the second movable opening / closing plate 47 by a connecting plate 51.

The alloy 52 is incorporated so that the opening and closing modes of the cooling outlet 33 and the heating outlet 34 are reversed. That is, as shown in FIG. 8, in the cooling outlet 33, when the air-conditioning air is cold air, the cooling outlet 33 is in an open state by the biasing force of the bias spring. The memory alloy 52 changes shape to the shape memory side and is closed. Therefore, the cooling outlet 33 is largely opened when the cool air is blown. On the heating outlet 34 side, when the air-conditioning air is at a low temperature, the heating outlet 34 is closed by the biasing force of the bias spring, and when the air-conditioning air becomes hot air, the shape memory alloy 52 is shaped. The shape changes to the memory side and is released. Accordingly, the heating outlet 34 is largely opened when the hot air is blown.

Next, the operation of this embodiment will be described.
