Description

  The present invention relates to a sleeping capsule, and particularly relates to air conditioning measures in a sleeping room.

  Conventionally, there are sleeping capsules in which an air outlet and a suction opening are formed in the sleeping chamber of the capsule body (see, for example, Patent Document 1).

The sleep capsule is configured such that an evaporator is installed in the middle of an air passage connecting the suction port and the air outlet, and the air cooled by the evaporator is blown out to the sleeping room. Specifically, after the room air in the sleeping room is sucked from one suction port under the sleeping person's feet and cooled, the conditioned air is blown out from the one outlet under the sleeping person's feet into the sleeping room. . The sleeping capsule is air-conditioned so that the entire sleeping room is uniform at a set temperature desired by the sleeping person.

  However, the conventional sleeping capsules described above have a problem that they are not suitable for the thermophysiological comfort of the human body. In other words, considering the optimal temperature for each part of the human body, the temperature distribution of the so-called “head cold foot heat”, which is the lowest on the head side and gradually increases as it goes to the foot, is suitable for the thermophysiological comfort of the human body. . On the other hand, the conventional air-conditioning control of the sleep capsule simply controls the sleep room so that the entire sleep room becomes the set temperature, and lacks the comfort of the sleeping person.

  Therefore, the temperature of the conditioned air blown out from the air outlet on the head side is higher than the temperature of the conditioned air blown out from the air outlet on the head side provided with the air outlet and the air inlet on each of the head side and the foot side in the sleeping room. A method of adjusting the air conditioning capacity of the conditioned air so as to be high can be considered. However, simply providing a vent on the foot side and blowing out conditioned air is warm air that blows out to the foot side, so it rises to the top of the sleeping room due to buoyancy, and foot heat that covers the foot There was a problem that it was difficult to form a space. Further, coupled with this rise in warm air, there is a problem that the cool air on the head side sinks into the lower part of the foot heat space, so that the foot heat space is damaged.

    The present invention has been made in view of such a point, and the object of the present invention is to provide an air-conditioning state so that a foot heat space suitable for the comfort of the sleeper is formed at least on the foot side of the sleeping room. Is to control.

  Specifically, the first invention includes a capsule body (20), a head air-conditioning means (13) that air-conditions the head side of the sleep room (11) in the capsule body (20), and the sleep room. And foot air conditioning means (14) for air conditioning the foot side in (11). And the said foot part air-conditioning means (14) has the blower outlet (71) which blows out conditioned air horizontally toward the head side from the foot part side of a sleep room (11), and the foot part side of a sleep room (11) Air flow space in which the conditioned air blown out from the air outlet (71) flows along the sleeping surface of the capsule body (20) on the foot side of the sleeping room (11). It is configured to form.

  In the above invention, air conditioning of the sleeping person's head is performed by the head air conditioning means (13), while air conditioning of the sleeping person's feet is performed by the foot air conditioning means (14). In particular, on the foot side of the sleep room (11), the air conditioning of the bed part of the sleeping person is performed by the airflow space of the conditioned air flowing along the sleeping surface and from the foot side toward the head side. That is, an airflow space that covers the sleeping person's feet is formed. Therefore, when the conditioned air blown from the air outlet (71) is warm air, the sleeping person is maintained in the temperature range of “foot heat”.

  Furthermore, in the above invention, since the conditioned air flows from the foot side toward the head side along the sleeping surface, when the conditioned air of the head air conditioning means (13) is cold air, the cold air foot side Intrusion is prevented. Thereby, since the airflow space on the foot side is not disturbed, the air conditioning of the sleeping person's foot is reliably performed.

  Further, the second invention is the above-mentioned first invention, wherein the foot air-conditioning means (14) has the air outlet (71) and protrudes from the sleeping surface at the foot side end of the capsule body (20). A foot air circulation section (70) is provided.

  In the above invention, the conditioned air surely blows out from the air outlet (71) toward the sleeping person's foot and flows along the sleeping surface. Therefore, the airflow space of the conditioned air that covers the sleeping person's feet is reliably formed.

  Further, the third invention is the above-mentioned second invention, wherein the suction port (72) of the foot air conditioning means (14) is formed on both sides of the air outlet (71) in the foot air circulation part (70). Yes.

  In the above invention, the indoor air on the foot side flows through both sides of the capsule body (20) and is sucked into the suction port (72). Therefore, the airflow space of the conditioned air is hardly disturbed by the intake air flow of the room air, so that an airflow space that covers the feet of the sleeping person is surely formed.

  Moreover, 4th invention is the said 2nd or 3rd invention. WHEREIN: The head (61) which the said head air-conditioning means (13) blows conditioned air to a sleeping room (11), and the head of a sleeping room (11) The head air circulation part (60) which has the suction inlet (62) which sucks the indoor air of the part side is provided. In the head air circulation part (60), the air inlet (62) is located below the air outlet (61), and an air flow that creates a short circuit between the air outlet (61) and the air inlet (62). It is configured to form a flow.

  In the above invention, conditioned air blown out from the air outlet (61) of the head air circulation part (60) to the sleeper (11) is sucked into the air inlet (62) on the head side of the sleeper (11). , Cause a local short circuit. That is, most of the conditioned air is sucked into the inlet (62) immediately from the outlet (61), so that a short circuit area is formed between the outlet (61) and the inlet (62). Air conditioning of the head is performed.

  Moreover, in said invention, since a suction inlet (62) is arrange | positioned under a blower outlet (61), when the conditioned air of a head air circulation part (60) is cold wind, for example, a lower suction inlet (62 ) Is reliably sucked in, and a short circuit area is reliably formed.

  Therefore, according to the first aspect, the conditioned air is blown horizontally from the foot side air outlet (71) so as to form an airflow space that flows from the foot side toward the head side along the sleeping surface. Therefore, when the conditioned air is warm air, it is possible to form a warm air flow space that covers the feet of the sleeping person. As a result, the sleeping person can be maintained in the temperature range of “foot heat”, and a sleep room (11) suitable for the thermophysiological comfort of the human body can be formed.

  Furthermore, since the conditioned air flows from the foot side to the head side along the sleeping surface, when the conditioned air on the head side is cold air, the cold air flows through the lower part of the sleeping room (11) It is possible to prevent intrusion to the part side. Thereby, since the warm air flow space is not disturbed, the sleeping person can be reliably maintained in the temperature range of “foot heat”.

  In particular, according to the second invention, the air outlet (71) is formed in the foot air circulation part (70) provided to protrude from the sleeping surface at the foot side edge of the capsule body (20). The conditioned air can surely flow along the sleeping surface and from the foot side toward the head side. Thereby, the warm air flow space which covers a sleeping person's foot | leg part can be formed easily and reliably.

  According to the third aspect of the present invention, since the suction port (72) on the foot side is provided on both sides of the air outlet (71), the airflow space of the conditioned air formed on the foot portion of the sleeping person is disturbed. It is possible to inhale indoor air on the foot side from both sides without any problem. As a result, the sleeping person can be maintained in the temperature range of “foot heat”.

  According to the fourth invention, the head air circulation part (60) is provided on the head side of the sleeping room (11), and the suction port (62) is arranged below the blowout port (61) to form a short circuit. Therefore, it is possible to form a short circuit region to form an airflow space that covers the head of the sleeping person. In particular, since the suction port (62) is arranged below the air outlet (61), when the conditioned air is cold air, the air is reliably sucked into the lower air inlet (62). A short circuit region can be formed.

  Moreover, since the airflow space of the conditioned air can be formed on the head side and the foot side of the sleeping room (11), if the temperature of the conditioned air blown out from each outlet (61, 71) is individually controlled, the part of the human body Based on another optimum temperature, the sleeper can be maintained in a temperature distribution of “head cold foot heat” that has the lowest head and gradually increases toward the foot. Therefore, it is possible to form a sleep room (11) more suitable for the thermophysiological comfort of the human body. As a result, the comfort of the sleeping person can be improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

And the suction passage communicates the suction port (62) and the return air port (35) of the head air conditioning unit (30F).

  As shown in FIG. 2, the blower outlet (61) and the suction inlet (62) of the said head air circulation part (60) are formed in the same rectangular shape. And the said blower outlet (61) and the suction inlet (62) are located in the vicinity, and the suction inlet (62) is located in the straight downward direction of the blower outlet (61). In addition, in this embodiment, although the said blower outlet (61) and the suction inlet (62) are formed in the same opening area, the opening area of a blower outlet (61) is more than the opening area of a suction inlet (62). It may be formed larger and the draft flow rate may be reduced to effectively prevent drafting of the bedridden head.

Control. By these controls, a temperature distribution of “head cold foot heat” is formed, and a state suitable for the thermophysiological comfort of the human body can be achieved.

-Driving action-
Next, the air conditioning operation of the sleep capsule (10) described above will be described. The sleep capsule (10) is switched between a cooling operation and a heating operation. Here, the operation of the cooling operation will be mainly described.

  In this cooling operation, both the head air conditioning unit (30F) and the foot air conditioning unit (30R) are driven. First, a sleeping person who takes a nap or the like enters the sleeping room (11) in the bed (22), and the covering member (23) folded on the head side is rotated to the foot side and deployed. To fully close and go to bed. Then, the sleeper sets the set temperature ST1 using the operation box. This set temperature ST1 is input to the controller (12). At the time of non-sleeping, the covering member (23) is folded and fully opened.

  When the air conditioning fan (32) and exhaust heat fan (33) of the head air conditioning unit (30F) are driven, the air in the sleeping room (11) enters the air conditioning passageway (36) from the return air port (35) on the head side. Inhaled. The air in the air conditioning passage (36) passes through the first fin group (42) of the thermoelectric element (41) in the heat exchange member (40) and is heated or cooled to generate conditioned air.

  This conditioned air flows from the air supply port (34) into the head air circulation part (60), flows through the blowout passage, and blows out from the blowout port (61) to the sleeping room (11). That is, as indicated by broken lines in FIG. 5, most of the conditioned air that blows out from the air outlet (61) of the head air circulation section (60) blows out to the bed of the sleeping person and enters the suction port (52) below. Inhaled.

  The air sucked into the suction port (62) of the head air circulation part (60) flows through the suction passage, and flows from the return air port (35) on the head side to the air conditioning passage (36). Thereafter, the air in the air conditioning passage (36) returns to the air conditioning fan (32) through the heat exchange member (40), and the above-described operation is repeated.

  On the other hand, outside air is introduced into the exhaust heat passage (37) from the outside air inlet (3a). The air in the exhaust heat passage (37) passes through the exhaust heat fan (33), is heated by, for example, the second fin group (43) of the thermoelectric element (41), and passes through the exhaust heat port (3b) to the air port ( 2a) is discharged outside the room.

  The drain generated in the first fin group (42) of the thermoelectric element (41) drops on the drain receiver (39), then flows to the evaporation heater (38) and evaporates, and the exhaust port (3b ) And discharged to the outside together with the air in the exhaust heat passage (37).

  Thus, in the head air circulation part (60) which is the head side of the sleeping room (11), conditioned air is blown out from the air outlet (61) to the sleeping room (11). 62) is located below, causing a local short circuit. Thereby, most of the conditioned air is sucked into the suction port (62), and a short circuit region is formed in front of the blower outlet (61) and the suction port (62). Therefore, an airflow space of conditioned air covering the sleeping person's head is formed, and air conditioning of the sleeping person's head is performed.

  On the other hand, when the air conditioning fan (32) and the exhaust heat fan (33) of the foot air conditioning unit (30R) are driven, the air in the sleeping room (11) flows from the suction port (72) of the foot air circulation part (70). It is sucked and flows from the return port (35) to the air conditioning passageway (36). The air in the air conditioning passage (36) passes through the first fin group (42) of the thermoelectric element (41) in the heat exchange member (40) and is heated or cooled to generate conditioned air.

  The conditioned air flows from the air supply port (34) into the foot air circulation unit (70), flows through the blowout passage, and blows out horizontally from the blowout port (71) to the sleeping room (11). The blown-out conditioned air flows toward the head side along the sleeping surface of the bed (22) as shown by a solid line in FIG. 5, and then gradually by buoyancy at the center in the front-rear direction of the bed (22). To rise. This raised conditioned air collides with the ceiling of the covering member (50), and then flows along the ceiling surface to the head side and the foot side. The conditioned air flowing to the foot side is sucked into the two suction ports (72). In this way, the conditioned air blown from the outlet (71) flows at least through the feet of the sleeping person, and an airflow space for the conditioned air is formed in the feet. That is, if the conditioned air is blown out from the air outlet (71) at an appropriate wind speed, the conditioned air is warm, but does not rise immediately due to buoyancy, but flows through the bedside of the sleeping person.

  Moreover, a part of the conditioned air blown out from the air outlet (61) of the head air circulation part (60) flows in the lower part of the sleeping room (11) toward the foot side, Since it is interrupted by the airflow space, the airflow space is not disturbed (see part A in FIG. 5). Thereby, the foot heat space which is an air current space of warm air can be reliably formed in the sleeping person's foot. In addition, the conditioned air which blows off from the said blower outlet (61) is adjusted only (alpha) degreeC higher than preset temperature ST1 by the thermoelectric element (41). That is, the temperature of the conditioned air on the foot side is higher than the temperature of the conditioned air on the head side. The flow of various air in the foot air conditioning unit (30R) is the same as that in the head air conditioning unit (30F) described above.

  On the other hand, in the heating operation, only the foot air conditioning unit (30R) is driven. The sleeper enters the sleeping room (11) and sets the set temperature ST2 using the operation box. This set temperature ST2 is input to the controller (12). The driving operation in the foot air conditioning unit (30R) and the air flow on the foot side of the sleeping room (11) are the same as in the cooling operation described above.

  Next, the temperature distribution state of the sleeping room (11) formed by the cooling operation and the heating operation described above will be described with reference to FIGS. Here, T1 to T7 in the figure indicate predetermined temperature ranges, respectively, and the temperature increases in the order of T1, T2,. 6 and 8 show a longitudinal section at the center in the width direction of the sleeping capsule (10), and FIGS. 7 and 9 show a height of 20 mm from the bed (22) surface of the sleeping room (11). The horizontal cross section is shown.

  The sleeping room (11) in the cooling operation is in a temperature distribution state as shown in FIGS. Specifically, on the head side of the sleeping room (11), the front of the air outlet (61) and the suction port (62) is generally a temperature region of T1, and the central part from the head side of the sleeping room (11). In FIG. 2, the lower part, which is the sleeping position of the sleeping person, is approximately the temperature region of T2, T3, and T4. On the foot side of the sleeping room (11), the suction port (72) and both sides are generally in the temperature region of T3 and T4, and the temperature region is generally in the range of T5 and T6 from the air outlet (71) to the center. In particular, the region along the sleeping surface which is the position of the sleeping person's foot is the highest T6 temperature region. Here, it can be seen that the temperature region of T2 and T3 and the temperature region of T6 are clearly partitioned at the lower center of the sleeping room (11) (see part A in FIG. 6). That is, it can be seen that intrusion of cool air is reliably prevented on the foot side, and a warm air flow space is formed to cover the bed part of the sleeping person (see A part of FIG. 7). Further, since the indoor air on the foot side is sucked from both sides of the air outlet (71), the warm air flow space is not disturbed.

  The sleeping room (11) in the heating operation is in a temperature distribution state as shown in FIGS. Specifically, from the head side to the center of the sleeping room (11), the temperature region is generally T3 and T4. On the foot side of the sleeping room (11), the temperature region is approximately T6 and T7, and the region along the sleeping surface, which is the position of the sleeping person's foot, is the highest T7 temperature region. Here again, as in the case of the cooling operation, it can be seen that a warm air flow space is reliably formed and covers the feet of the sleeping person (see section A in FIG. 9). That is, in any of the above-described operations, the sleep room (11) has a temperature distribution of “head cold foot heat” in which the temperature is the lowest in the sleeping person's head and gradually increases toward the foot.

  In this way, on the foot side, the conditioned air blown out from the air outlet (71) flows from the foot side toward the head side along the sleeping surface, thereby preventing the intrusion of cold air and the warm air flow space. Can be formed.

-Effect of the embodiment-
As described above, according to the present embodiment, conditioned air is blown horizontally from the foot side air outlet (71), and an airflow space that flows from the foot side toward the head side along the sleeping surface is formed. Since it did in this way, when the said conditioned air is warm air, the warm air flow space which covers a leg part of a sleeper can be formed. As a result, the sleeping person can be maintained in the temperature range of “foot heat”, and the sleep room (11) suitable for the thermophysiological comfort of the human body can be formed.

  In addition, since conditioned air flows from the foot side toward the head side along the sleeping surface, cold air on the head side is prevented from flowing into the foot side through the lower part of the sleep chamber (11). be able to. Thereby, the airflow space is not disturbed.

  In particular, since the air outlet (71) is provided in the foot air circulation part (70) standing on the sleeping surface at the foot side end of the floor (21), the conditioned air is surely provided along the sleeping surface. Can be shed. Moreover, since the said suction inlet (72) was provided in the both sides of the blower outlet (71), indoor air can be suck | inhaled, without disturbing the airflow space which covers a sleeper's foot | leg part. Thereby, the temperature region of “foot heat” can be reliably formed.

  Furthermore, since the head air circulation part (60) is provided on the head side of the sleep room (11), the suction port (62) is arranged below the air outlet (61) to cause a short circuit, An airflow space that covers the sleeping person's head by forming a short circuit area can be formed. In particular, since the conditioned air of the head air circulation part (60) is cold air, it is surely sucked into the lower suction port (62), so that a short circuit region can be reliably formed.

  In addition, because the air flow space of conditioned air is formed on both the head side and the foot side of the sleep room (11) and the temperature of the conditioned air blown out from each outlet (61, 71) is individually controlled, the human body A sleep room (11) suitable for the thermophysiological comfort of can be formed. That is, the bedridden can be maintained in a temperature distribution of “head cold foot heat” that has the lowest head and gradually increases toward the legs based on the optimum temperature for each part of the human body. As a result, the comfort of the sleeping person can be improved.

  Further, since the air outlet (71) and the suction port (72) are arranged side by side in the foot air circulation section (70), the height of the foot air circulation section (70) is the head air circulation. It is considerably lower than the part (60). Therefore, it is possible to suppress the feeling of pressure given to the occupant in the indoor space when the covering member (50) is in the fully open state when not sleeping. As a result, the sleeping capsule (10) suitable for the living space can be provided.

<< Other Embodiments >>
The present invention may be configured as follows with respect to the above embodiment.

  For example, in the above embodiment, both the air outlet (71) and the suction port (72) are provided in the foot air circulation part (70), but the present invention provides only the air outlet (71) in the foot part. You may make it provide in an air distribution part (70). In that case, you may make it provide the said suction inlet (72) in the leg side edge part in the both sides of a floor stand (21), for example. That is, in this case, the suction port (72) opens upward.

  In each of the above embodiments, the cover member (50) is rotated between the head side and the foot side of the capsule body (20) to open and close, but the left side of the capsule body (20). It may be a single-open type that opens and closes by rotating between the right side and the right side, or a double-open type that opens and closes by rotating from the center in the width direction of the capsule body (20) to the left and right.

  Further, on the head side of the sleep room (11), the head air circulation part (60) is provided to form the air flow space of the conditioned air on the head side. Other means may be used as long as a short circuit is formed between the air outlet (61) and the air inlet (62) to form a short circuit area covering the head of the sleeping person.

  The heat exchange member (50) is not limited to the thermoelectric element (51), and may be an evaporator or a condenser of a vapor compression refrigeration cycle.

  As described above, the present invention is useful as a sleep capsule having an air conditioning function.
