It goes down.

  As described above, in the physiological function activating device of Patent Document 1, the target temperature of the air conditioner is gradually increased or decreased to give the occupant a warm stimulus and a cool stimulus. .

JP 2009-41795 A

  In the physiological function activating device disclosed in Patent Literature 1, a predetermined gradient is given to the target temperature of the air conditioner, and the target temperature is gradually changed. For this reason, since the ambient temperature of the occupant gradually changes, the thermal stimulation and the cold stimulation applied to the occupant become weak, and the physiological function cannot be activated sufficiently.

  This invention is made | formed in view of this point, The objective is to improve the activation effect | action of a physiological function in a physiological function activation apparatus.

A first invention is directed to a physiological function activating device, and an air conditioning unit (20) that changes a room temperature to give a thermal stimulus and a cold stimulus to a human body, and a predetermined for giving the thermal stimulus to the human body. A temperature setting unit (43a) in which a high temperature side target temperature and a predetermined low temperature side target temperature that is lower than the high temperature side target temperature and that gives the cold stimulation to the human body are set, and the air conditioning unit (20) A high temperature holding operation in which the target temperature is held at the high temperature side target temperature for a predetermined time, and a low temperature holding operation in which the target temperature of the air conditioning unit (20) is held at the low temperature side target temperature for a predetermined time. An air conditioning control unit (50) for performing a temperature fluctuation operation executed at least once, and in the temperature fluctuation operation, the other operation is performed after the end of one of the high temperature holding operation and the low temperature holding operation. There is executed, the real of the high-temperature holding operation Time, characterized that you have longer than the execution time of the low-temperature holding operation.

  Here, the “high temperature side target temperature” is a target temperature for giving a desired thermal stimulus to the human body among the temperatures of the air in the vicinity of the human body. Further, the “low temperature side target temperature” here is a target temperature for giving a desired cold stimulus to the human body among the temperatures of the air in the vicinity of the human body.

  In the first invention, the high temperature side target temperature and the low temperature side target temperature are set in the temperature setting section (43a). In the temperature fluctuation operation, the high temperature holding operation and the low temperature holding operation are alternately executed at least once. When the high temperature holding operation is executed, the target temperature of the air conditioning unit (20) is held at the high temperature side target temperature. Thereby, the temperature around the human body is increased and thermal stimulation is applied to the human body. As a result, for example, the peripheral blood vessels of the human body are expanded. On the other hand, when the low temperature holding operation is executed, the target temperature of the air conditioning unit (20) is held at the low temperature side target temperature. Thereby, the temperature around the human body is lowered, and a cold stimulus is applied to the human body. As a result, for example, the peripheral blood vessels of the human body contract. As described above, in the temperature fluctuation operation, the high-temperature holding operation and the low-temperature holding operation are alternately performed at least once, so that the thermal stimulus and the cold stimulus are applied to the human body.

  In the present invention, when one of the high temperature holding operation and the low temperature holding operation is completed, the other operation is performed after the completion. Specifically, for example, the high temperature holding operation is executed, the target temperature of the air conditioning unit (20) becomes the high temperature side target temperature, and when this high temperature holding operation ends, the low temperature holding operation is executed thereafter. For example, when the low temperature holding operation is executed and the target temperature of the air conditioning unit (20) becomes the low temperature side target temperature, and this low temperature holding operation ends, the high temperature holding operation is executed thereafter. When the other operation is executed after one operation in this way, the temperature around the human body can be rapidly changed. As a result, it is possible to apply steep thermal stimulation or cold stimulation to the human body.

In the temperature fluctuation operation of the first invention , the execution time of the high temperature holding operation for applying the thermal stimulus to the human body is longer than the execution time of the cold holding operation for applying the cold stimulus to the human body. Therefore, in this temperature fluctuation operation, since it takes a relatively long time to apply the thermal stimulus to the human body, it becomes easier to dilate the peripheral blood vessels of the human body. Thereby, the improvement effect of cooling property can be accelerated | stimulated. In other words, when having coldness, peripheral skin blood vessels tend to contract. On the other hand, in the temperature fluctuation operation of the present invention, the time for applying the thermal stimulus to the human body is lengthened and the skin peripheral blood vessels are actively expanded, so the effect of improving the cooling property is enhanced.

The second invention is directed to a physiological function activating device, and an air conditioning unit (20) that changes a room temperature to give a thermal stimulus and a cold stimulus to a human body, and a predetermined for giving the thermal stimulus to the human body. A temperature setting unit (43a) in which a high temperature side target temperature and a predetermined low temperature side target temperature that is lower than the high temperature side target temperature and that gives the cold stimulation to the human body are set, and the air conditioning unit (20) A high temperature holding operation in which the target temperature is held at the high temperature side target temperature for a predetermined time, and a low temperature holding operation in which the target temperature of the air conditioning unit (20) is held at the low temperature side target temperature for a predetermined time. An air conditioning control unit (50) for performing a temperature fluctuation operation executed at least once, and in the temperature fluctuation operation, the other operation is performed after the end of one of the high temperature holding operation and the low temperature holding operation. Is equivalent to the skin temperature of the human body The storage unit (51) for storing a predetermined reference temperature and the low temperature side target temperature and the reference temperature as the wind speed of the air reaching the human body from the air conditioning unit (20) increases during the low temperature holding operation. the difference between the so decreases, characterized that you have further comprising a target temperature correcting unit for correcting the low temperature-side target temperature and (52).

In the second invention, the target temperature correction unit (52) is set in the temperature setting unit (43a) in accordance with the wind speed of air supplied from the air conditioning unit (20) and reaching the human body (hereinafter referred to as reaching air). Correct the lower temperature target temperature. In other words, the cold stimulus given to the human body changes not only according to the temperature of the reaching air, but also strictly depending on the wind speed of the reaching air. This is because when the wind speed of the arrival air changes, the amount of heat absorbed by the human body and the amount of heat released from the human body change, and accordingly, the thermal stimulation also changes. Therefore, in the present invention, considering this point, the low-temperature side target temperature is corrected according to the wind speed of the reaching air. As a result, a more optimal cold stimulus can be given to the human body.

In the second invention, the target temperature correction unit (52) brings the low temperature side target temperature closer to the reference temperature (temperature corresponding to the surface temperature of the human skin (for example, 30 °)) as the wind speed of the reaching air increases. In other words, correction is performed so that the lower temperature side target temperature is separated from the reference temperature as the wind speed of the reaching air decreases. In other words, the cold stimulus given to the human body increases as the wind speed of the reaching air increases, and decreases as the wind speed decreases.

Therefore, the target temperature correction unit (52) performs correction to bring the low temperature side target temperature closer to the reference temperature in a situation where the wind speed of the reaching air increases and the cooling stimulus becomes too large. As a result, since the difference between the temperature of the reaching air and the skin temperature of the human body is reduced, the cold stimulation can be reduced. Therefore, it is possible to avoid excessive cooling and stimulation under a situation where the wind speed of the reaching air is high. Further, the target temperature correction unit (52) corrects the low temperature side target temperature away from the reference temperature in a situation where the wind speed of the reaching air becomes small and the cooling / heating stimulus becomes too small. As a result, the difference between the temperature of the reaching air and the skin temperature of the human body is increased, so that the thermal stimulation can be increased. Therefore, it is possible to avoid a lack of cold stimulation under a situation where the wind speed of the reaching air is low.

A third invention is directed to a physiological function activating device, and an air conditioning unit (20) that changes a room temperature to give a thermal stimulus and a cold stimulus to a human body, and a predetermined for giving the thermal stimulus to the human body. A temperature setting unit (43a) in which a high temperature side target temperature and a predetermined low temperature side target temperature that is lower than the high temperature side target temperature and that gives the cold stimulation to the human body are set, and the air conditioning unit (20) A high temperature holding operation in which the target temperature is held at the high temperature side target temperature for a predetermined time, and a low temperature holding operation in which the target temperature of the air conditioning unit (20) is held at the low temperature side target temperature for a predetermined time. An air conditioning control unit (50) for performing a temperature fluctuation operation executed at least once, and in the temperature fluctuation operation, the other operation is performed after the end of one of the high temperature holding operation and the low temperature holding operation. Is equivalent to the skin temperature of the human body And the high temperature side target temperature and the reference temperature as the wind speed of the air reaching the human body from the air conditioning unit (20) increases during the high temperature holding operation. as the difference becomes smaller and, it characterized that you have further comprising a target temperature correcting unit for correcting the high-temperature-side target temperature and (52).

In the third invention, the target temperature correction unit (52) is set in the temperature setting unit (43a) according to the wind speed of the air (hereinafter referred to as reaching air) supplied from the air conditioning unit (20) and reaching the human body. The corrected high temperature side target temperature is corrected. That is, the thermal stimulus given to the human body changes not only according to the temperature of the reaching air but also strictly depending on the wind speed of the reaching air. This is because when the wind speed of the reaching air changes, the amount of heat absorbed into the human body and the amount of heat released from the human body change, and the thermal stimulus also changes accordingly. Therefore, in the present invention, in consideration of this point, the high-temperature side target temperature is corrected according to the wind speed of the reaching air. As a result, it is possible to give a more optimal thermal stimulus or cooler stimulus to the human body.

The target temperature correction unit (52) of the third invention corrects the high temperature side target temperature to a reference temperature (a temperature corresponding to the surface temperature of the human skin (for example, 30 °)) as the wind speed of the reaching air increases. In other words, as the wind speed of the reaching air decreases, the high temperature side target temperature is corrected away from the reference temperature. That is, the thermal stimulus given to the human body increases as the wind speed of the reaching air increases, and decreases as the wind speed decreases.

Therefore, the target temperature correction unit (52) performs correction to bring the high temperature side target temperature closer to the reference temperature in a situation where the wind speed of the reaching air increases and the thermal stimulation becomes too large. As a result, since the difference between the temperature of the reaching air and the skin temperature of the human body is reduced, thermal stimulation can be reduced. Therefore, it is possible to avoid excessive thermal stimulation under conditions where the wind speed of the reaching air is high. The target temperature correction unit (52) corrects the high temperature side target temperature away from the reference temperature in a situation where the wind speed of the reaching air is low and the thermal stimulus is too low. As a result, the difference between the temperature of the reaching air and the skin temperature of the human body is increased, so that the thermal stimulation can be increased. Therefore, it is possible to avoid the lack of thermal stimulation under the circumstances where the wind speed of the reaching air is low.

A fourth invention is directed to a physiological function activating device, and includes an air conditioning unit (20) that changes a room temperature to give a thermal stimulus and a cold stimulus to a human body, and a predetermined for giving the thermal stimulus to the human body. A temperature setting unit (43a) in which a high temperature side target temperature and a predetermined low temperature side target temperature that is lower than the high temperature side target temperature and that gives the cold stimulation to the human body are set, and the air conditioning unit (20) A high temperature holding operation in which the target temperature is held at the high temperature side target temperature for a predetermined time, and a low temperature holding operation in which the target temperature of the air conditioning unit (20) is held at the low temperature side target temperature for a predetermined time. An air conditioning control unit (50) for performing a temperature fluctuation operation executed at least once, and in the temperature fluctuation operation, the other operation is performed after the end of one of the high temperature holding operation and the low temperature holding operation. Is executed during the above temperature fluctuation operation. A target temperature correction unit (52) that corrects one or both of the low temperature side target temperature and the high temperature side target temperature according to the wind speed of air reaching the human body from the air conditioning unit (20), The target temperature correction unit (52) is configured to perform correction to bring the low temperature side target temperature or the high temperature side target temperature close to a predetermined reference temperature corresponding to the skin temperature of the human body as the wind speed of the air increases. The target temperature correction unit (52) increases the low temperature side target temperature or the high temperature side target temperature in accordance with the wind speed of the air as the difference between the low temperature side target temperature or the high temperature side target temperature with respect to the reference temperature increases. Configured to increase the correction range
It has been characterized by Rukoto.

The target temperature correction unit (52) of the fourth aspect of the invention relates to the low temperature side target corresponding to the wind speed of the air as the difference between the reference temperature and the low temperature side target temperature or the difference between the reference temperature and the high temperature side target temperature is large. Increase the correction range of the temperature or high temperature side target temperature. That is, for example, when the difference between the reference temperature and the high-temperature side target temperature is relatively large, the thermal stimulus given to the human body greatly changes as the wind speed of the reaching air changes. Therefore, in the present invention, under a situation where the difference between the reference temperature and the high temperature side target temperature is large, the correction range of the high temperature side target temperature corresponding to the change in the air wind speed is increased. Similarly, for example, when the difference between the reference temperature and the low-temperature side target temperature is relatively large, the cold stimulus given to the human body greatly changes as the wind speed of the reaching air changes. Therefore, in the present invention, under a situation where the difference between the reference temperature and the low temperature side target temperature is large, the correction range of the low temperature side target temperature corresponding to the change in the air wind speed is increased.

In the temperature fluctuation operation of the sixth aspect of the invention, the low temperature holding operation is first executed, and the high temperature holding operation is executed after the low temperature holding operation is completed. Thereby, since the temperature around a human body rises rapidly, a steep thermal stimulus can be given to a human body. When this high temperature holding operation ends, the low temperature holding operation is executed again after the high temperature holding operation. Thereby, since the temperature around the human body is suddenly lowered, it is possible to apply a steep cooling / heating stimulus to the human body.

Thereby, thermal stimulation is given to a human body. When the high temperature holding operation ends, the low temperature holding operation is performed after the end. Thereby, since the temperature around the human body is suddenly lowered, it is possible to apply a steep cooling / heating stimulus to the human body.

According to an eighth invention, in the seventh invention, when the temperature fluctuation operation starts, the high temperature holding operation is executed, the low temperature holding operation is executed after the high temperature holding operation is completed, and the high temperature holding operation is executed after the low temperature holding operation is completed. The holding operation is performed again.

In the temperature fluctuation operation of the eighth aspect of the invention, the high temperature holding operation is first executed, and the low temperature holding operation is executed after the high temperature holding operation is completed. Thereby, since the temperature around the human body is suddenly lowered, it is possible to apply a steep cooling / heating stimulus to the human body. When this low temperature holding operation is completed, the high temperature holding operation is performed again after the completion. Thereby, since the temperature around a human body rises rapidly, a steep thermal stimulus can be given to a human body.

In 9th invention, the target temperature (low temperature side target temperature) of the air-conditioning part (20) in low temperature holding operation | movement is set in the range of 18 degreeC or more and 22 degrees C or less. Here, if the low temperature side target temperature becomes too low, the comfort in the room is impaired. Moreover, when the low temperature side target temperature becomes too high, it is not possible to give an appropriate cold stimulus to the human body. Therefore, in the present invention, the low temperature side target temperature is set to 18 ° C. or more and 22 ° C. or less in order to achieve both of them.

A tenth aspect of the invention is characterized in that, in any one of the first to ninth aspects, the high temperature side target temperature set in the temperature setting section (43a) is 28 ° C. or higher and 32 ° C. or lower. .

In the tenth aspect of the invention, the target temperature (high temperature side target temperature) of the air conditioning unit (20) in the high temperature holding operation is set within a range of 28 ° C. or higher and 32 ° C. or lower. Here, if the high temperature side target temperature becomes too high, the comfort in the room is impaired. Moreover, when the high temperature side target temperature becomes too low, it is not possible to give an appropriate thermal stimulus to the human body.

As a result, for example, the function of the peripheral blood vessels of the skin can be activated, and the physiological function of the human body can be effectively activated. Therefore, it can promote blood pressure regulating action, blood circulation regulating action, body temperature regulating action, etc. of the human body, thereby improving coldness, preventing hypertension, preventing metabolism / repair function from being lowered, promoting fatigue recovery, heat stroke prevention, etc. Can be achieved.

That is, in these inventions, not only the temperature of the air in the vicinity of the human body but also the wind speed of the reaching air is taken into consideration, so that it is possible to apply an optimal cold stimulus or thermal stimulus to the human body. Therefore, the physiological function of the human body can be more effectively activated.

According to the fifth aspect of the invention, the low temperature holding operation is first executed, and then the high temperature holding operation is executed. For this reason, a sharp thermal stimulus can be given to the human body. According to the sixth aspect of the invention, the high temperature holding operation is first executed, and then the low temperature holding operation is executed.

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

  The physiological function activation device (10) according to Embodiment 1 of the present invention activates the physiological function of the human body by giving a thermal stimulus and a cold stimulus to the human body. As shown in FIG. 1, the physiological function activation device (10) includes a room air conditioner (20) as an air conditioning unit.

  The room air conditioner (20) constitutes a heat pump refrigeration apparatus (air conditioner) that performs a vapor compression refrigeration cycle. That is, the room air conditioner (20) includes a refrigerant circuit (21) that performs a refrigeration cycle by circulating refrigerant (see FIG. 2). A compressor (22), an outdoor heat exchanger (23), an expansion valve (24), an indoor heat exchanger (25), and a four-way switching valve (26) are connected to the refrigerant circuit (21). The compressor (22) is configured as an inverter type having a variable capacity. The expansion valve (24) is composed of, for example, an electronic expansion valve.

  In the refrigerant circuit (21), the flow path of the refrigerant is changed as the four-way switching valve (26) is switched. Thereby, in the refrigerant circuit (21), a refrigeration cycle in which the outdoor heat exchanger (23) serves as a condenser and the indoor heat exchanger (25) serves as an evaporator (refrigeration cycle in which the refrigerant flows in the direction of the solid line arrow in FIG. 2). And a refrigeration cycle (a refrigeration cycle in which the refrigerant flows in the direction of the broken line arrow in FIG. 2) in which the outdoor heat exchanger (23) serves as an evaporator and the indoor heat exchanger (25) serves as a condenser can be changed. .

The indoor unit (30) includes a horizontally long casing (31). In the casing (31), a suction port (32) is formed on the front side and / or upper part, and a blower outlet (33) is formed on the lower part. An air passage is formed in the casing (31) from the inlet (32) to the outlet (33). The air passage is provided with the indoor heat exchanger (25) and the indoor fan (27) described above. When the indoor fan (27) is operated, the air in the indoor space (S) is taken into the casing (31) through the suction port (32). After passing through the indoor heat exchanger (25), this air is supplied to the indoor space (S) through the air outlet (33). The indoor fan (27) constitutes an air blowing unit that supplies air to the human body. Further, the indoor fan (27) is configured such that the rotational speed of the fan motor is variable.

  As shown in FIG. 3, the physiological function activating device (10) includes a setting unit (40) and an air conditioning control unit (50).

  Various operating parameters related to the room air conditioner (20) are set in the setting unit (40). The setting unit (40) includes an operation switching setting unit (41), a normal operation setting unit (42), and a variable operation setting unit (43).

  The operation switching setting unit (41) is a switch for switching the operation of the room air conditioner (20). The operation mode of the room air conditioner (20) is roughly classified into “normal operation” and “forge operation”. The “normal operation” is an operation for performing air conditioning so that the temperature of the indoor space (S) approaches a temperature desired by the user (air conditioning target temperature). This “normal operation” includes “cooling operation” in which a refrigeration cycle using an indoor heat exchanger (25) as an evaporator and “heating operation” in which a refrigeration cycle using an indoor heat exchanger (25) as a condenser are performed. are categorized. Further, the “training operation” is an operation for activating the physiological functions of the occupants in the indoor space (S). That is, the “training operation” is a temperature fluctuation operation in which a thermal stimulus and a cold stimulus are given to the human body by changing the temperature of the indoor space (S).

  In the normal operation setting unit (42), operation parameters related to normal operation of the room air conditioner (20) are set. Specifically, the normal operation setting unit (42) includes an air conditioning temperature setting unit (42a), an air volume setting unit (42b), and an air direction setting unit (42c).

  The set temperature Ts in the room to be air-conditioned by the room air conditioner (20) is input to the air conditioning temperature setting unit (42a). That is, the target temperature of the room air conditioner (20) during normal operation is set in the air conditioning temperature setting unit (42a).

  In the air volume setting unit (42b), the air volume of the air (blowing air) blown out from the air outlet (33) is input / set for the room air conditioner (20) during normal operation. Note that the air volume of the blown air can be changed, for example, by controlling the rotational speed of the motor of the indoor fan (27). Further, the wind direction of the air blown from the room air conditioner (20) during normal operation is input / set in the wind direction setting unit (42c). In addition, the wind direction of blowing air can be changed by controlling the flap (airflow control board) provided in the blower outlet (33), for example.

  In the variable operation setting section (43), operation parameters relating to the training operation of the room air conditioner (20) are set. Specifically, the fluctuating operation setting unit (43) is provided with a stimulation temperature setting unit (43a) and a fluctuation pattern setting unit (43b).

  In the stimulation temperature setting unit (43a), a high temperature side target temperature Tmax and a low temperature side target temperature Tmin are set as target temperatures of the room air conditioner (20) during the training operation. The “high temperature side target temperature Tmax” is a temperature for applying a thermal stimulus to the human body during the training operation, and is an environmental temperature for dilating the peripheral blood vessels of the human body. That is, the high temperature side target temperature Tmax is a target temperature for giving a desired thermal stimulus to the human body among the temperatures of the air in the vicinity of the human body. In the present embodiment, the high temperature side target temperature Tmax is 28 ° C. The high temperature side target temperature Tmax is not limited to 28 ° C., but is preferably 28 ° C. or more and 32 ° C. or less. The “low temperature side target temperature Tmin” is a temperature for applying a cold stimulus to the human body during the training operation, and is an environmental temperature for contracting the peripheral blood vessels of the human body. That is, the low temperature side target temperature Tmin is a target temperature for giving a desired cold stimulus to the human body among the temperatures of the air in the vicinity of the human body. In this embodiment, the low temperature side target temperature Tmin is 22 ° C. The low temperature side target temperature Tmin is not limited to 22 ° C. as long as it is lower than the high temperature side target temperature Tmax, but is preferably 18 ° C. or more and 22 ° C. or less.

  In the fluctuation pattern setting unit (43b), a fluctuation pattern of the target temperature is set, such as how to change the target temperature of the room air conditioner (20) during the training operation with the passage of time. Specifically, as shown in FIG. 4, the change pattern setting unit (43b) sets the target temperature of the room air conditioner (20) in the order of Tmin → Tmax → Tmin, from the start to the end of the training operation. A variation pattern to be changed is set. That is, in the present embodiment, when the operation of holding the target temperature of the room air conditioner (20) at the low temperature side target temperature (low temperature holding operation) is completed, the operation of holding the target temperature of the room air conditioner (20) at the high temperature side target temperature. (High temperature holding operation) is executed, and when this high temperature holding operation is completed, the low temperature holding operation is executed again.

  In the variation pattern setting unit (43b) of the present embodiment, times (t1, t2, t3) for executing the above-described operations are set. In the present embodiment, the first time t1 is set to 12.5 minutes, the second time t2 is set to 35 minutes, and the third time t3 is set to 12.5 minutes. In other words, in this embodiment, the time during which the high temperature holding operation is executed (time t2 in this embodiment) is longer than the time during which the low temperature holding operation is executed (time t1 and time t3 in this embodiment). ing. In this embodiment, the execution time of the low temperature holding operation immediately before the high temperature holding operation (time t1 in this embodiment) and the execution time of the low temperature holding operation immediately after the high temperature holding operation (time t3 in this embodiment). ) Is set to the same time (for example, 12.5 minutes).

  The air conditioning control unit (50) controls the room air conditioner (20) based on various operating parameters set in the setting unit (40), and constitutes a controller for normal operation and training operation is doing. The air conditioning control unit (50) controls, for example, the operating frequency of the compressor (22), the rotational speed of the indoor fan (27), the opening of the expansion valve (24), the setting of the four-way switching valve (26), etc. It is configured.

-Driving action-
The operation of the physiological function activating device (10) will be described.

<Normal operation>
First, normal operation of the room air conditioner (20) will be described. In the normal operation of the room air conditioner (20), the cooling operation and the heating operation are switched.

  In cooling operation, four-way switching is performed so that the discharge side of the compressor (22) communicates with the outdoor heat exchanger (23) and at the same time the suction side of the compressor (22) communicates with the indoor heat exchanger (25). Valve (26) is set. When the compressor (22) is operated from this state, the refrigerant discharged from the compressor (22) condenses in the outdoor heat exchanger (23) and is depressurized by the expansion valve (24), and then the indoor heat exchange is performed. Flow through the vessel (25) (see solid arrow in FIG. 2).

  When the indoor fan (27) is operated in the room air conditioner (20) during the cooling operation, the air in the indoor space (S) is introduced into the casing (31) from the suction port (32). The air introduced into the casing (31) flows through the air passage and passes through the indoor heat exchanger (25). In the indoor heat exchanger (25), the refrigerant absorbs heat from the air and evaporates, and the air is cooled. The refrigerant evaporated in the indoor heat exchanger (25) is sucked into the compressor (22) and compressed. The air cooled by the indoor heat exchanger (25) is supplied to the outside of the casing (31) (that is, the indoor space (S)) through the air outlet (33).

  During heating operation, the four-way switching is performed so that the discharge side of the compressor (22) communicates with the indoor heat exchanger (25) and at the same time the suction side of the compressor (22) communicates with the outdoor heat exchanger (23). Valve (26) is set. When the compressor (22) is operated from this state, the refrigerant discharged from the compressor (22) flows through the indoor heat exchanger (25) (see the broken line arrow in FIG. 2).

  Further, when the indoor fan (27) is operated in the room air conditioner (20) during the heating operation, the air in the indoor space (S) is introduced into the casing (31) from the suction port (32). The air introduced into the casing (31) flows through the air passage and passes through the indoor heat exchanger (25). In the indoor heat exchanger (25), the refrigerant dissipates heat into the air and condenses, and the air is heated. The refrigerant condensed in the indoor heat exchanger (25) is depressurized by the expansion valve (24) and then evaporated by the outdoor heat exchanger (23), and is sucked into the compressor (22) and compressed. The air heated by the indoor heat exchanger (25) is supplied to the outside of the casing (31) (that is, the indoor space (S)) through the air outlet (33).

  In the normal operation (cooling operation or heating operation) as described above, the temperature of the indoor space (S) to be air-conditioned by the room air conditioner (20) approaches the set temperature Ts set in the air-conditioning temperature setting unit (42a). As such, the capacity of the room air conditioner (20) is controlled. Specifically, for example, a suction temperature sensor (35) is provided in the suction port (32) of the room air conditioner (20) of the present embodiment. The air conditioning control unit (50) controls the operating frequency and start / stop of the compressor (22) so that the temperature of the air (suction air) detected by the suction temperature sensor (35) approaches the set temperature Ts. I do. Thereby, in the cooling operation or the heating operation, the temperature of the air in the indoor space (S) converges to the set temperature Ts.

<Training operation>
Next, the training operation of the room air conditioner (20) will be described. When the operation mode of the operation switching setting unit (41) is set to “forging operation” and the operation is started, the following training operation is performed.

  As shown in FIG. 4, when the training operation is started, a low temperature holding operation is performed over a time t1. That is, at the time t1 (12.5 minutes), the target temperature of the room air conditioner (20) becomes the low temperature side target temperature Tmin (22 ° C.). That is, the air conditioning control unit (50) controls the room air conditioner (20) so that the temperature around the occupants in the indoor space (S) approaches Tmin. More specifically, the air conditioning control unit (50), for example, operates the operating frequency and the generator of the compressor (22) so that the temperature of the intake air detected by the suction temperature sensor (35) approaches the low temperature side target temperature Tmin. Control stop.

  As described above, when the low temperature holding operation is executed, the room occupant is given a cold stimulus. As a result, the peripheral blood vessels of the occupants contract. And such a cold stimulus is continuously given to the occupant over time t1. Therefore, at time t1, the occupant's peripheral skin blood vessels are surely contracted. In order to reliably contract the peripheral blood vessels of the occupants in this way, it is preferable to set the execution time (t1) of the first low-temperature holding operation to 12.5 minutes or more.

  When the first low temperature holding operation ends after the time t1 has elapsed, the high temperature holding operation is executed immediately after the end. That is, at the time t2 (35 minutes), the target temperature of the room air conditioner (20) becomes the high temperature side target temperature Tmax (28 ° C.). That is, the air conditioning control unit (50) controls the room air conditioner (20) so that the temperature around the occupant in the indoor space (S) approaches Tmax. More specifically, the air conditioning control unit (50), for example, determines the operating frequency and the frequency of the compressor (22) so that the temperature of the intake air detected by the intake temperature sensor (35) approaches the high temperature side target temperature Tmax. Control stop.

  As described above, when the high temperature holding operation is performed immediately after the low temperature holding operation is finished, the temperature around the occupant rapidly increases. For this reason, steep thermal stimulation is given to the person in the room. As a result, the peripheral blood vessels of the occupant rapidly expand. Then, such thermal stimulation is continuously given to the occupants over time t2. For this reason, at time t2, the skin peripheral blood vessels that were in the contracted state until immediately before the start of the high-temperature holding operation can be reliably brought into the expanded state. In order to reliably expand the peripheral blood vessels of the occupants in this way, it is preferable to set the execution time (t2) of the high temperature holding operation to 35 minutes or more.

  In addition, in the case of a cold occupant, the skin peripheral blood vessels tend to be in a contracted state. For this reason, by making the execution time of the high-temperature holding operation immediately after the execution time of the first low-temperature holding operation longer, it becomes easier to transition the skin peripheral blood vessels of such chilled occupants to the expanded state. .

  When the time t2 elapses and the high temperature holding operation ends, the second low temperature holding operation is executed immediately after the end. That is, at the time t3 (12.5 minutes), the target temperature of the room air conditioner (20) becomes the low temperature side target temperature Tmin (22 ° C.) again. Thereby, the temperature around the occupant falls to the low temperature side target temperature Tmin. As a result, the occupant is given a steep cold stimulus, and the peripheral blood vessels of the occupant rapidly contract. Note that if the execution time of the second low-temperature holding operation is too short, the cold stimulus provided to the occupants becomes insufficient. For this reason, the execution time (t3) of the second low temperature holding operation is preferably 12.5 minutes or more.

  When the time t3 elapses and the second low temperature holding operation is completed, the training operation is finished and the normal operation is automatically executed. As a result, the target temperature of the room air conditioner (20) becomes the set temperature Ts, and the above-described cooling operation and heating operation are performed. Therefore, after the training operation, the temperature of the indoor space (S) approaches the set temperature Ts, so that the comfort of the indoor space (S) is promptly improved.

-Effect of the embodiment-
As described above, in the training operation of the present embodiment, the low temperature holding operation and the high temperature holding operation are alternately executed in a cycle of the low temperature holding operation → the high temperature holding operation → the low temperature holding operation. In the present embodiment, when the first low temperature holding operation is completed, the high temperature holding operation is executed immediately after the completion, and when this high temperature holding operation is completed, the second low temperature holding operation is executed immediately after the completion. For this reason, in the training operation, the ambient temperature of the occupant can be rapidly increased or decreased. As a result, it is possible to apply sufficient cold and thermal stimulation to the occupants and improve the physiology of the occupants (particularly the function of peripheral blood vessels).

  FIG. 5 shows the result of experimental verification on this point. FIG. 5 compares the change in fingertip skin temperature by immersing the fingertip in cold water before and after receiving the training operation. Here, the broken line in FIG. 5 shows the change in the fingertip skin temperature of the subject before undergoing the training operation. Moreover, the continuous line of FIG. 5 shows the change of the fingertip skin temperature of the subject who received the training operation once a day for one week continuously.

  As shown in FIG. 5, in the period of immersing the fingertips in cold water, it is possible to observe a tendency that the function of the peripheral blood vessels is improved after the training operation than before the training operation. Specifically, the minimum fingertip skin temperature during the period of immersing the fingertip in cold water increased by about 0.5 ° C. due to the training operation. In addition, as shown in the figure, it can be observed that the fingertip skin temperature is more likely to rise after receiving the training operation than before receiving the training operation even after the fingertip is lifted from the cold water. .

  As described above, it can be seen that the physiological function of the human body (function of peripheral blood vessels) can be improved by receiving the training operation of the present embodiment. Therefore, according to the present embodiment, it is possible to promote the blood pressure regulating action, blood circulation regulating action, body temperature regulating action, etc. of the human body, thereby improving coldness, preventing hypertension, preventing the metabolism / repair function from being lowered, and recovering from fatigue. Promotion, prevention of heat stroke, etc. can be aimed at.

  Moreover, in the training operation of the said embodiment, only two types, high temperature side target temperature Tmax and low temperature side target temperature Tmin, are used as the target temperature of a room air conditioner (20). Therefore, for example, the room air conditioner (20) can be easily controlled as compared with a case where a larger number of target temperatures during the training operation are set.

<< Other Embodiments >>
About the said embodiment, it is good also as following structures.

<Temperature fluctuation pattern of training operation>
You may employ | adopt the variation pattern different from the said embodiment as a variation pattern of the training operation set to a variation operation setting part (43). That is, the variation pattern set in the variation pattern setting unit (43b) is not limited to the above embodiment.

  Specifically, the variation pattern of the training operation shown in FIG. 6 is to change the target temperature of the room air conditioner (20) in the order of Tmax → Tmin → Tmax. That is, in the training operation of the example shown in FIG. 6, the high temperature holding operation and the low temperature holding operation are alternately performed in a cycle of high temperature holding operation → low temperature holding operation → high temperature holding operation, and then normal operation is performed. Also in the training operation of this example, by performing the low temperature holding operation immediately after the end of the first high temperature holding operation, it is possible to apply a steep cold heat stimulus to the human body. Further, by performing the high temperature holding operation immediately after the end of the subsequent low temperature holding operation, it is possible to apply a steep thermal stimulus to the human body.

  Moreover, as shown in FIG.7 and FIG.8, you may make it perform a low temperature holding operation and a high temperature holding operation once each in a training operation. That is, in the training operation shown in FIG. 7, the low temperature holding operation and the high temperature holding operation are alternately executed in a cycle of the low temperature holding operation → the high temperature holding operation, and then the normal operation is performed. In the training operation shown in FIG. 8, the high temperature holding operation and the low temperature holding operation are alternately executed in a cycle of the high temperature holding operation → the low temperature holding operation, and then the normal operation is performed. Even in these examples, a rapid thermal holding operation is performed immediately after the end of the low temperature holding operation, or a rapid low temperature holding operation is performed immediately after the end of the high temperature holding operation, thereby applying a sharp thermal stimulus or a cold stimulus to the human body. can do.

  In addition, as a variation pattern of the training operation, the number of times that the low temperature holding operation and the high temperature holding operation are alternately repeated may be set to be larger than that in the above embodiment. That is, according to the present invention, the number of times of each operation may be any number as long as the low temperature holding operation and the high temperature holding operation are alternately performed at least once.

<Configuration of air conditioning unit>
In the said embodiment, a room air conditioner (20) is used as an air-conditioning part which changes indoor temperature. However, for example, a fan coil unit, a heater, a Peltier element, or the like may be used as the air conditioning unit (20). That is, the air conditioning unit (20) may be any means as long as it can heat or cool the air.

<Automatic operation program>
In the above embodiment, the normal operation is automatically performed when the training operation is completed. As such an automatic operation program, a program that always executes the training operation once a day for a predetermined period (for example, one week) may be used. In this case, the training operation is automatically executed over a predetermined period (for example, one week) without the user selecting / inputting “forging operation” as the operation mode every day. As a result, the user or the like can be reliably and continuously subjected to the training operation, so that the physiological function of the user can be improved reliably.

<Modification with target temperature correction unit>
In the above embodiment, the high temperature side target temperature Tmax and the low temperature side target temperature Tmin may be corrected. Specifically, as shown in FIG. 9, in the physiological function activation device (10) of the first modification, the air conditioning control unit (50) includes a storage unit (51) and a target temperature correction unit (52). Yes.

  The storage unit (51) supplies data (wind speed) that correlates the wind speed of air that has been supplied to the human body from the air outlet (23) and has reached the human body (hereinafter referred to as reaching air) and the temperature of the reaching air. -Temperature map) is stored (see Fig. 10). This data was obtained experimentally in order to give an optimal cold stimulus or thermal stimulus to the human body. On the other hand, the target temperature correction unit (52) corrects the high temperature side target temperature Tmax and the low temperature side target temperature Tmin according to the wind speed of the reaching air based on the wind speed-temperature map stored in the storage unit (51). It is.

  The wind speed-temperature map will be described in more detail. In the wind speed-temperature map, for example, Sc1 and Sc2 are stored as characteristics (cooling stimulation side characteristics) for correcting the low temperature side target temperature Tmin according to the wind speed. For example, Sc1 is a no-wind condition (ie, wind speed = 0 m / s), and a cold stimulus (cool-heat stimulus at point a in FIG. 10) when the temperature of the air around the human body is 18 ° C. This is a relationship between the wind speed and temperature of the reaching air to cause the human body to be given a cold heat stimulus equivalent to the cold heat stimulus under a windy condition where air directly hits the human body. That is, even if the wind speed and temperature of the reaching air change, a cold stimulus corresponding to point a is applied to the human body at any location as long as it is on the line Sc1. Similarly, Sc2 is a cold stimulus when there is no wind and the temperature of the air in the vicinity of the human body is 22 ° C. (cool stimulus at point b in FIG. 10), and a cool stimulus equivalent to the cool stimulus at point b. Is the relationship between the wind speed of the reaching air and the air for applying to the human body under windy conditions. In the wind speed-temperature map, a plurality of cold-stimulation side characteristics other than Sc1 and Sc2 are also stored in the region Rc, but the illustration is omitted in FIG. 10 for convenience.

  Further, for example, Sh1 and Sh2 are stored in the wind speed-temperature map as characteristics (thermal stimulation side characteristics) for correcting the high temperature side target temperature according to the wind speed. For example, Sh1 is a thermal stimulus when the temperature of the air in the vicinity of the human body is 28 ° C. in a no wind state (ie, wind speed = 0 m / s), It is the relationship between the wind speed and temperature of reach | attained air for giving a human body the thermal stimulus equivalent to a thermal stimulus also in a windy condition. Similarly, Sh2 is a thermal stimulus when the temperature of the air in the vicinity of the human body is 32 ° C. in a no wind state (ie, wind speed = 0 m / s), This is a relationship between the wind speed and temperature of the reaching air for applying a thermal stimulus equivalent to the thermal stimulus at point d to the human body even under a windy condition. In the wind speed-temperature map, a plurality of thermal stimulation side characteristics (not shown) other than Sh1 and Sh2 are also stored in the region Rh, but are not shown in FIG. 10 for convenience.

  Each characteristic (Sc1, Sc2, Sh1, Sh2) of the wind speed-temperature map tends to approach a reference temperature (Tb in FIG. 10 (eg, 30 ° C.)) corresponding to the surface temperature of the human skin as the wind speed increases. . The cold stimulus and the warm stimulus depend on the temperature difference ΔT between the temperature of the reaching air and the reference temperature and the wind speed of the reaching air, but if the same cool stimulus or the warm stimulus is given to the human body, the higher the wind speed, This is because the temperature difference ΔT can be small. In addition, each characteristic (Sc1, Sc2, Sh1, Sh2) of the wind speed-temperature map is more dependent on the wind speed when the characteristic away from the reference temperature (for example, Sc1) than the characteristic closer to the reference temperature (for example, Sc2). The variation range of air temperature is large. This is because the greater the difference between the reference temperature and the air temperature, the easier it is to change the cold stimulus or the hot stimulus as the wind speed changes.

  During the training operation of this modification, the target temperature correction unit (52) corrects the low temperature side target temperature Tmin and the high temperature side target temperature Tmax based on such a wind speed-temperature map.

  Specifically, for example, in the low temperature holding operation described above, the low temperature side target temperature Tmin is set to 18 ° C. (point a in FIG. 10). In this case, Tmin is corrected on the characteristic Sc1 of the wind speed-temperature map. Here, for example, it is assumed that the wind speed of the air reaching the human body is 0.8 m / s. In this case, the temperature at point a1 (for example, 21 ° C.) corresponding to the wind speed of 0.8 m / s on Sc1 is updated as the low temperature side target temperature Tmin. Similarly, for example, it is assumed that the wind speed of air reaching the human body is 1.4 m / s. In this case, the temperature at point a2 (for example, 22 ° C.) corresponding to the wind speed of 1.4 m / s on Sc1 is updated as the low temperature side target temperature Tmin. Similarly, when the low temperature side target temperature Tmin at the initial stage of the low temperature holding operation is 22 ° C., the same correction is performed on the characteristic Sc2 of the wind speed-temperature map.

  In the above-described high temperature holding operation, the high temperature side target temperature Tmax is similarly corrected based on the characteristics Sh1, the characteristics Sh2, and the like. Specifically, for example, it is assumed that the high temperature side target temperature Tmin is set to a temperature (for example, 28 ° C.) lower than the reference temperature. In this case, correction is performed so that the high-temperature side target temperature Tmax increases (approaches the reference temperature) as the wind speed of the reaching air increases. Conversely, it is assumed that the high temperature side target temperature Tmax is set to a temperature (for example, 35 ° C.) higher than the reference temperature. In this case, correction is performed so that the high-temperature side target temperature Tmax decreases (approaches the reference temperature) as the wind speed of the reaching air increases.

  Note that the wind speed of the air reaching the human body can be directly detected by, for example, a wind speed sensor or the like. For example, the air volume of the indoor fan (27), the flap angle of the air outlet (33), the room air conditioner (20) It can also be obtained indirectly based on the distance between the human body and the human body. Further, the distance between the room air conditioner (20) and the human body can be obtained by designating a position for the user to receive the training operation in advance or by detecting the position of the human body using an infrared sensor or the like.

  As described above, in this modification, the target temperature correction unit (52) corrects Tmax and Tmin to approach the reference temperature Tb as the wind speed of the reaching air increases. In this correction, the correction range of Tmax and Tmin is increased as the temperature difference between Tmax and Tmin with respect to the reference temperature Tb is increased. For this reason, in this modification, it is possible to perform an operation that fully considers the amount of heat released from the human body and the amount of heat absorbed by the human body due to the wind speed of the air, and more optimal cold stimulation and thermal stimulation are given to the human body. can do. Moreover, in this modification, since air close to the reference temperature is supplied to the room under a condition where the wind speed is high, it is possible to avoid that the room temperature is extremely cold or extremely high.

  In this modification, the target temperature correction unit (52) corrects both the high temperature side target temperature Tmax and the low temperature side target temperature Tmin, but only one of them is corrected. Also good.

< Reference example with air flow control unit>
You may make it change the wind speed of the air which reaches | attains a human body, using the wind speed-temperature map shown in FIG. 10 mentioned above. That is, in the reference example shown in FIG. 11, the storage unit (51) and the wind speed control unit (53) are provided in the air conditioning control unit (50). In the storage unit (51), as in the first modification, data relating the wind speed and temperature of the reaching air is stored. On the other hand, the reference example is configured to change the wind speed of the air reaching the human body according to the temperature of the reaching air.

  Specifically, for example, in the low temperature holding operation, the low temperature side target temperature Tmin is set to 18 ° C. (point a in FIG. 10). On the other hand, in this low temperature holding operation, it is assumed that the temperature of the air reaching the human body from the room air conditioner (20) is, for example, 21 ° C. In this case, the wind speed (1.4 m / s) of air at point a1 corresponding to a temperature of 21 ° C. on Sc1 is the target wind speed. Therefore, in this case, the air volume of the indoor fan (27) (the rotational speed of the fan motor) is controlled so that the wind speed of the reaching air approaches the target wind speed. Similarly, when the low temperature side target temperature Tmin at the initial stage of the low temperature holding operation is 22 ° C., the wind speed of the reaching air is controlled on the characteristic Sc2 of the wind speed-temperature map. Further, in the above-described high temperature holding operation, the wind speed of the reaching air is controlled based on the characteristics Sh1 and the characteristics Sh2.

As described above, in this reference example, since the wind speed of air is controlled in accordance with the temperature change of the air reaching the human body, it is possible to apply an optimal cold stimulus or thermal stimulus to the human body. The temperature of the air reaching the human body can be obtained by directly detecting the temperature in the vicinity of the human body with a temperature sensor, or indirectly by detecting the temperature of the intake air of the room air conditioner (20), for example. You can ask for it.

<Modified example with intermediate target temperature Tmid set>
In each of the above-described embodiments, the low temperature side target temperature Tmin for applying a thermal stimulus to the human body and the high temperature side target temperature Tmax for applying a thermal stimulus to the human body are set, and the high temperature holding operation is performed after the low temperature holding operation. Alternatively, the low temperature holding operation is performed after the high temperature holding operation. However, an intermediate target temperature Tmid, which is a temperature between the high temperature side target temperature Tmax and the low temperature side target temperature Tmin, is set, and during the transition from the low temperature holding operation to the high temperature holding operation, or from the high temperature holding operation to the low temperature holding operation. In the meantime, an intermediate temperature holding operation for holding the target temperature at the intermediate target temperature Tmid may be performed.

  Specifically, for example, in the example shown in FIG. 12, the target temperature is changed in the order of low temperature holding operation → intermediate holding operation → high temperature holding operation → intermediate holding operation → low temperature holding operation. Note that the modified example in which such an intermediate holding operation is introduced is not limited to this. For example, the target temperature is changed in the order of high temperature holding operation → intermediate holding operation → low temperature holding operation → intermediate holding operation → high temperature holding operation. Alternatively, other patterns may be used.

  In addition, the above embodiment is an essentially preferable illustration, Comprising: It does not intend restrict | limiting the range of this invention, its application thing, or its use.

  As described above, the present invention is useful for a physiological function activation device that activates a physiological function of a human body by applying a thermal stimulus and a cold stimulus to the human body.
