Note that the temperature of the sleeping person's head and legs is not particularly limited, and a temperature setting button or the like is provided on the front plate (20) of the headboard (70) so that the sleeping person can set the set temperature appropriately. Also good.

-Driving action-
Next, operation | movement of the said bed (1) with an air conditioner is demonstrated based on FIGS.

    First, the sleeping person opens the curtain (47) of the canopy (40) of the bed (1), enters the sleeping space (14) above the bed (11), and closes the curtain (47). Start sleeping.

    The controller (80) detects the start of bedtime of the sleeper and starts the control of the air conditioner (50) automatically or manually by the sleeper. Thereby, in the head side air conditioning unit (60), energization of the head side heat source (91) and driving of each fan (95, 96) are started, and in the leg side air conditioning unit (51), the leg side fan (55) and Energization of the leg-side heat source (54) is started. Further, the temperature control unit (81) appropriately controls the current value flowing through the electric heater (54a) and the head-side heat source (91) and the rotational speed of each fan (55, 95, 96).

    In the sleeping space (14), on the sleeping person's head side, as shown in FIG. 7, the air in the sleeping space (14) (from the head side inlet (33b) of the duct member (30) of the headboard (20)) RA1) is inhaled. As shown in FIGS. 4 and 5, the sucked air (RA1) passes through the second head side opening (75b) of the top panel (75) and the use side passage (83) of the head side air conditioning unit (60). And passes through the use side heat exchange section (92) of the head side heat source unit (90) to become cooled head side conditioned air (SA1). The head-side conditioned air (SA1) passes through the use-side fan (95) and flows out from the first head-side opening (75a) of the top panel (75). The head-side conditioned air (SA1) then goes to bed from the head-side outlet (33) of the partition plate (32) through the head-side intermediate outlet (33a) of the lower plate (33) of the duct member (30). It flows out upward to the person's head side space. As shown in FIG. 7, the outflowed head-side conditioned air (SA1) flows so as to spread downward from the upper side of the sleeping person's head side, so that the head-side space of the sleeping person becomes a predetermined temperature. Then, the air is sucked again from the head side suction port (32b) of the duct member (30).

    Further, in the exhaust heat side passage (84) of the head side air conditioning unit (60), the air (OA) outside the sleeping space (14) becomes the second ventilation grill of the back plate (22) of the board body (20a). It is taken in from the exhaust heat side suction port (71a) via (22a) and is heat-treated in the exhaust heat side heat exchange section (92). The heated air (OA) flows between the transpiration plates (94d) of the transpiration plate unit (94) to evaporate the drain absorbed by the transpiration plates (94d). Thereafter, the air (OA) flows out from the exhaust heat side blower outlet (73a) through the exhaust heat side fan (96) together with the vapor of the drained drain, and flows into the side plate (23) of the headboard (20). Outflow from the third ventilation grille (23a).

    On the other hand, in the sleeping space (14), on the leg side of the sleeping person, as shown in FIG. 7, air (RA2) on the leg side of the sleeping person is sucked from the leg side inlet (19). As shown in FIG. 6, the sucked leg-side air (RA2) is fed into the leg side from the second leg-side opening (52b) formed in the side surface of the leg-side casing (52) of the leg-side air conditioning unit (51). It is taken into the casing (52). The taken leg-side air (RA2) passes through the leg-side fan (55), passes through the leg-side heat source (54), and becomes heated leg-side humidified air (SA2). The leg-side conditioned air (SA2) flows out from the leg-side outlet (18) of the bed (11) through the first leg-side opening (52b) of the leg-side casing (52). As shown in FIG. 7, the leg-side conditioned air (SA2) flowing out from the leg-side outlet (18) rises in the inward direction and then descends so that the leg-side space of the sleeper reaches a predetermined high temperature. The air is conditioned and is sucked into the leg side suction port (19) again. When the conditioned air (SA2) rises, it goes inward and descends at a predetermined height as it rises along the curtain (47) of the canopy (40) shown in FIG. 47) to collide.

-Effect of the embodiment-
In this embodiment, since the head-side air conditioning unit (60) is housed in the board body (20a) of the headboard (20), the head-side air conditioning unit (60) is placed in the bed portion (11) as in the prior art. The distance from the heat source (91) of the head side air conditioning unit (60) to the space on the head side of the sleeping person can be shortened as compared with the one disposed below the head. As a result, it is possible to reduce the heat loss generated when the head-side air conditioning unit (60) performs air conditioning on the sleeper's head and the necessary power of the user-side fan (95). Ease of control and energy saving can be achieved. Furthermore, since the use-side fan (95) can be reduced in size, the head-side air conditioning unit (60) can be sized to be housed in the board body (20a). Moreover, the noise of the user-side fan (95) is reduced and does not disturb the sleep of the sleeper.

    In addition, the bed (1) includes a canopy (40) and covers the upper part of the bed part (11) to form a sleeping space (14), so that the air conditioning unit (51, 60) is adapted to air conditioning. Therefore, it is possible to prevent the air having the appropriate temperature from flowing out of the sleeping space (14). Thereby, since the sleeping section (14) can be kept in a comfortable air-conditioned state, comfort at the time of sleeping of the sleeping person is improved.

    Furthermore, since the temperature control unit (81) of the controller (80) causes the temperature of the leg side of the sleeper to be higher than the temperature of the head side, “head cold foot heat” suitable for different comfort of the human body. Therefore, the comfort of the sleeping person at bedtime is further improved.

    Further, in the duct part (30) of the headboard (20), the head side outlet (32a) is formed so as to open upward in the center of the partition plate (32), and the head side inlet (33b) is Since it was formed on both sides of the lower plate (33) below the partition plate (32), the head side conditioned air (SA1) flows upward from the head side outlet (32a) and Since the bed flows downward in the width direction of the bed part (11), it is possible to reduce the feeling of the draft of the sleeper, and the head side conditioned air (SA1) is An airflow is formed so as to cover the entire head side.

    In addition, since the leg-side air outlet (18) is formed in the both-side space (17) and the leg-side inlet (19) is formed in the leg-side space (16) on the upper surface of the bed (11), the leg The conditioned air (SA2) flowing out from the side air outlet (18) rises so as to cross the leg side of the sleeping person diagonally inward, and then is sucked into the leg inlet (19). As a result, almost the entire leg side of the sleeping person can be covered with the conditioned air (SA2), so that the air conditioning on the leg side of the sleeping person can be reliably performed.

    Moreover, in the said head side air conditioning unit (60), since the head side heat source (91) was comprised with the Peltier element, the head side heat source unit (90) can be formed compactly. Further, in the present embodiment, in the head side air conditioning unit (91), the devices (90, 95, 96) are arranged so as to be arranged in the horizontal direction and not in the front-rear direction. ) Is short and has a configuration suitable for a long shape in the horizontal direction.

    On the other hand, in the said leg side air conditioning unit (51), since the leg side heat source (54) was comprised with the electric heater, it is not necessary to provide an exhaust heat passage. Accordingly, the air conditioning unit (51) is configured in a compact manner, and the configuration of the air conditioning unit (51) is simplified.

<< Other Embodiments >>
