  Moreover, the air conditioner 20 is provided with the detection part 30 which detects a user's biometric information. As shown in FIG. 5, the detection unit 30 and the heater 32 are provided in the seat unit 10. The heater 32 is provided at a location different from the detection unit 30 so as not to overlap the detection unit 30. The heater 32 heats the seat portion 10. As the heater 32, for example, an electric heater can be used. In addition, as the heater 32, the thing of the structure which discharge | releases radiant heats, such as a halogen heater, can also be used.

  The detection unit 30 uses the pressure-sensitive tube 31 to detect vibrations such as a user's pulse when the user is seated on the seat 10. As the detection unit 30, for example, a known biological information acquisition device such as a biological information acquisition device disclosed in WO2017 / 195234 can be used. For this reason, the structure and detection principle of the detection unit 30 of the present embodiment are the same as those of the biological information acquisition apparatus. Thereby, when the user is seated on the seat 10, the user's heart rate, fluctuation of the heart rate interval, and the like can be detected.

  The air conditioning control unit 41 uses the stress state determination table in which the autonomic nerve balance (LF / HF), the parasympathetic nerve index (HF), the autonomic nerve activity (SDNN), and the stress state are associated with each other. Determine. Here, the parasympathetic nerve index (HF) and the autonomic nerve activity (SDNN) are both parameters relating to the heartbeat interval (beat-related parameters), and are parameters suitable for grasping the current stress state of the user.

  Autonomic nerve balance (LF / HF) is an index of the balance between a user's sympathetic nerve and parasympathetic nerve. HF and LF correspond to one of two peaks obtained when frequency analysis of the heartbeat interval is performed. Specifically, HF represents a high frequency component (for example, 0.20 Hz or more), and LF represents a low frequency component (for example, a region of 0.05 Hz to 0.20 Hz). HF appears when the parasympathetic nerve is superior to the sympathetic nerve (ie, when the parasympathetic nerve is activated), and LF is when the sympathetic nerve is dominant and when the parasympathetic nerve is dominant (ie, the sympathetic nerve is It appears both when activated and when parasympathetic nerves are activated. Therefore, the more stressful state in which the sympathetic nerves are activated, the higher the value of the autonomic nerve balance LF / HF, indicating that the autonomic nerve balance is poor. On the contrary, in the relaxed state, the parasympathetic nerve is activated more than in the overstressed state, and therefore the value of the autonomic nerve balance LF / HF is lower than that in the overstressed state. In this case, it is shown that the balance of the autonomic nerve is in a good state.

  The parasympathetic nerve index HF and the autonomic nerve activity level SDNN are obtained from the heartbeat interval in the same manner as the autonomic nerve balance LF / HF. As described above, the parasympathetic nerve index HF has a lower value as it is overstressed, and conversely has a higher value as it is in a relaxed state. The autonomic nerve activity level SDNN indicates the result of the standard deviation of the heartbeat interval, that is, the degree of dispersion of the heartbeat interval. The more normal the autonomic nerve functions, the more the fluctuations that are motivated by breathing and blood pressure appear as fluctuations in the heart rate interval. If the autonomic nerve does not function normally due to drugs or the like, fluctuations in the heartbeat interval are less likely to appear. For this reason, the greater the standard deviation of the heartbeat interval, the higher the value of the autonomic nerve activity level SDNN, indicating that there is an autonomic nerve activity. Conversely, the smaller the standard deviation of the heartbeat interval, the lower the value of the autonomic nerve activity level SDNN, indicating that the autonomic nerve activity is poor.

  In the stress state determination table, the heart rate related parameter when each of the autonomic nerve balance LF / HF, the parasympathetic nerve index HF, and the autonomic nerve activity level SDNN, which are heart rate related parameters, is “high” or “low”. All the combinations are shown, and the user's stress state in each combination is shown in any one of the first state to the eighth state. Such a stress state determination table is stored in the storage unit 42. Table 1 shows an example of the stress state determination table.

As can be seen from Table 1, the first state is a state in which the autonomic nerve balance, the parasympathetic nerve index, and the autonomic nerve activity are all “high”. The second state is a state where both the autonomic nerve balance and parasympathetic nerve indices are “high” and the autonomic nerve activity is “low”. The third state is a state in which the autonomic nerve balance is “high”, the parasympathetic nerve index is “low”, and the autonomic nerve activity is “high”. The fourth state is a state in which the autonomic nerve balance is “high” and the parasympathetic nerve index and the autonomic nerve activity are both “low”. The fifth state is a state in which the autonomic nerve balance is “low” and the parasympathetic nerve index and the autonomic nerve activity are both “high”. The sixth state is a state in which the autonomic nerve balance is “low”, the parasympathetic nerve index is “high”, and the autonomic nerve activity is “low”. The seventh state is a state in which the autonomic nerve balance and parasympathetic nerve are “low” and the autonomic nerve activity is “high”. The eighth state is a state where the autonomic nerve balance, the parasympathetic nerve index, and the autonomic nerve activity are all “low”.

  As shown in FIG. 6, the air conditioner 20 includes a control device 40 and an operation unit 50. The control device 40 controls the first blower 23, the second blower 26, and the heater 32. The air conditioning control unit 41 includes an air conditioning control unit 41, a storage unit 42, and a clock 43. For example, a radio clock is used as the clock 43, measures the date and time, and outputs it to the air conditioning control unit 41. The user's biological information detected by the detection unit 30 is input to the air conditioning control unit 41.

  The air conditioning control unit 41 includes an arithmetic processing unit that executes a predetermined control program. The arithmetic processing unit includes, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The air conditioning control unit 41 may include one or a plurality of microcomputers. The storage unit 42 stores various control programs and information used for various control processes. The storage unit 42 includes, for example, a nonvolatile memory and a volatile memory. The non-volatile memory includes, for example, a ROM (Read Only Memory), a hard disk, and a flash memory. The volatile memory includes, for example, a RAM (Random Access Memory).

  The operation unit 50 is communicably connected to the air conditioning control unit 41 by wire or wireless. The operation unit 50 is, for example, a remote controller, and is configured such that the control content of the first blower 23, the second blower 26, and the heater 32 by the air conditioning control unit 41 can be changed.

  In the chair 1 having such a configuration, the air conditioning control unit 41 controls at least one of air conditioning on the body part of the user who contacts the chair 1 and air conditioning on the body part of the user who does not touch the chair 1. In the present embodiment, the air conditioning control unit 41 controls the blowing of the user's neck and waist by the blowers 23 and 26 based on the user's biological information, and the heating of the user's buttocks by the heater 32 (seat unit 10). And the temperature of the surrounding air conditioning).

  The air conditioning control unit 41 of the present embodiment can individually control the operations of the first blower 23, the second blower 26, and the heater 32, and each can be changed in three stages. The air conditioning control unit 41 can change the average wind speed of each of the fans 23 and 26 and can change the amount of heat generated by the heater 32. In addition, the number of stages for changing the average wind speed of each of the blowers 23 and 26 and the number of stages for changing the heat generation amount of the heater 32 can be arbitrarily changed.

  Each blower 23 and 26 is changed into three stages of H tap, M tap, and L tap. The average wind speed of each blower 23, 26 decreases in the order of H tap, M tap, and L tap (H tap average wind speed> M tap average wind speed> L tap average wind speed). An example of the average wind speed of the H tap of the first blower 23 is 0.7 m / s, an example of the average wind speed of the M tap is 0.24 m / s, and an example of the average wind speed of the L tap is 0.00. 15 m / s. An example of the average wind speed of the H tap of the second blower 26 is 1.2 m / s, an example of the average wind speed of the M tap is 0.65 m / s, and an example of the L tap is 0.4 m / s. It is.

  The heater 32 is changed into three stages of H tap, M tap, and L tap. The heat generation amount of the heater 32 decreases in the order of H tap, M tap, and L tap (H tap heat generation> M tap heat generation> L tap heat generation).

  The storage unit 42 stores a standard air conditioning pattern for each season. The standard air-conditioning pattern is an air-conditioning pattern composed of a combination of the wind speeds of the fans 23 and 26 and the amount of heat generated by the heater 32. The air-conditioning pattern in a state before acquiring the user's biometric information and the user's biometric information after acquiring And an air conditioning pattern. Such standard air conditioning patterns include a summer standard first standard air conditioning pattern, a winter standard second standard air conditioning pattern, and an intermediate (spring / autumn) standard third air conditioning pattern. An example of these standard air conditioning patterns is shown below as Table 2, Table 3, and Table 4.

Each standard air-conditioning pattern is not limited to Tables 2 to 4, and the standby mode operation and the reference mode operation can be arbitrarily changed and set. In addition, the standard air conditioning patterns are not limited to the above three types, and one, two types, or four or more types of standard air conditioning patterns may be set.

  The air conditioning control unit 41 according to the present embodiment executes start-up control and basic control as drive control for each of the blowers 23 and 26 and the heater 32. Details of the start control and basic control will be described below.

[Startup control]
The activation control is a control executed when the chair 1 is powered on, that is, when power is supplied to the chair 1. FIG. 7 is a flowchart illustrating an example of activation control processing.

  As shown in FIG. 7, the air-conditioning control unit 41 shifts to the standby mode after the start control is started in step S11. In the standby mode, the air conditioning control unit 41 acquires the date and time from the clock 43, and selects any one of the first standard air conditioning pattern, the second standard air conditioning pattern, and the third standard air conditioning pattern based on the date and time. In one example, the air-conditioning control unit 41 selects the first standard air-conditioning pattern that becomes summer specification in the case of from June 1 to September 30, and from December 1 to February 28 (or 29th). Select the second standard air-conditioning pattern for winter specifications, and select the third standard air-conditioning pattern for intermediate specifications for March 1st to May 31st or October 1st to November 30th. To do. The air conditioning control unit 41 controls the blowers 23 and 26 and the heater 32 based on the selected standard air conditioning pattern. Thus, the air-conditioning control unit 41 drives the blowers 23 and 26 when the power of the chair 1 is turned on.

  Next, the air conditioning control unit 41 determines whether or not the user is seated on the chair 1 in step S12. The air conditioning control unit 41 can determine whether the user is seated on the chair 1 based on the detection information of the detection unit 30.

  When the user is not seated on the chair 1 (step S12: NO), the air conditioning control unit 41 shifts to the standby mode of step S11. On the other hand, when the user is seated on the chair 1 (step S12: YES), the air conditioning control unit 41 acquires the biological information of the user in step S13. In step S <b> 13, the detection unit 30 measures biological information such as a user's heartbeat over a predetermined measurement time, and outputs the measurement result to the air conditioning control unit 41. Thereby, the air-conditioning control part 41 acquires a user's biometric information. An example of the predetermined measurement time is about 1 minute.

  Next, the air-conditioning control unit 41 sets an air-conditioning pattern in step S14 and ends the activation control. In step S14, the air conditioning control unit 41 controls each of the fans 23 and 26 and the heater 32 based on the standard air conditioning pattern selected in step S11 and the user's biological information acquired in step S13.

A specific example of the start control will be described.
When the season is summer, the summer standard first standard air conditioning pattern (Table 1) is selected as the standard air conditioning pattern. In this case, in the standby mode, the fans 23 and 26 are controlled by H taps, and the heater 32 is turned off. When the user is seated on the chair 1, the detection unit 30 measures the user's biological information over a predetermined time. In this predetermined time, each fan 23 and 26 is controlled by H tap, and the state where the heater 32 is turned off is maintained.

  After the detection unit 30 detects the user's biological information, the air conditioning control unit 41 determines a stress state based on the user's biological information, and controls each of the fans 23 and 26 and the heater 32 based on the determined stress state. . For example, when the user's stress state is the fourth state, the air conditioning control unit 41 sets the air conditioning pattern corresponding to the fourth state in the air conditioning pattern of the basic mode operation of Table 1. Thereby, the air-conditioning control unit 41 sets the blowers 23 and 26 to M taps, while maintaining the heater off. For example, when the user's stress state is the eighth state, the air conditioning control unit 41 sets the air conditioning pattern corresponding to the eighth state in the air conditioning pattern of the basic mode operation of Table 1. Thereby, the air-conditioning control part 41 changes each air blower 23 and 26 to L tap, and drives a heater with M tap.

[Basic control]
Basic control is control which drives each fan 23 and 26 and the heater 32 based on a user's biometric information after completion | finish of starting control. In the basic control, the user's biological information is repeatedly measured over the period in which the user is seated on the chair 1, and the fans 23 and 26 and the heater 32 are controlled based on the measured user's biological information. FIG. 8 is a flowchart illustrating an example of basic control processing.

  As shown in FIG. 8, the air conditioning control unit 41 determines whether or not the user is seated on the chair 1 in step S21. The determination in step S21 can be performed in the same manner as the determination in step S12 of the start control.

  When the user is not seated on the chair 1 (step S21: NO), the air conditioning control unit 41 shifts to the standby mode in step S22. On the other hand, when the user is seated on the chair 1 (step S21: YES), the air conditioning control unit 41 determines whether or not a predetermined time has elapsed in step S23.

  When the user's biological information has been measured in the basic control, the air conditioning control unit 41 determines whether or not a predetermined time has passed immediately after the previous measurement of the user's biological information. On the other hand, if the user's biological information is not measured in the basic control immediately after the basic control is started, has the air conditioning control unit 41 passed a predetermined time immediately after the measurement of the user's biological information in step S13 of the activation control? Determine whether or not. Here, an example of the predetermined time is about 10 minutes. Note that the predetermined time can be arbitrarily changed.

  When it is determined that the predetermined time has elapsed (step S23: YES), the air conditioning control unit 41 acquires the user's biological information in step S24, and sets the air conditioning pattern in step S25. Here, the method by which the air conditioning control unit 41 acquires the user's biological information is the same as in step S13 of activation control, and the method of setting the air conditioning pattern is the same as in step S14 of activation control.

  Next, the air conditioning control unit 41 determines whether or not the air conditioning pattern has been changed in step S26. When the user operates the operation unit 50 and changes the control content of the air-conditioning pattern during execution of the basic control (step S26: YES), the air-conditioning control unit 41 sets each blower 23 based on the air-conditioning pattern changed in step S27. , 26 and the heater 32 are controlled. And the air-conditioning control part 41 memorize | stores the change content in step S28, and transfers to step S29. On the other hand, if the air conditioning pattern has not been changed (step S26: NO), the air conditioning control unit 41 proceeds to step S29. Moreover, when it determines with the air conditioning control part 41 not having passed predetermined time (step S23: NO), it transfers to step S26. Note that step S28 may be executed before step S27, or step S27 and step S28 may be executed simultaneously.

  Next, the air conditioning control unit 41 determines whether or not an off operation has been performed in step S29. Examples of the off operation include a case where the user turns off the power of the chair 1 or stops basic control. For example, the user performs an off operation using the operation unit 50.

  If the air conditioning control unit 41 is not turned off (step S29: NO), the process proceeds to step S21. As described above, the air conditioning control unit 41 repeatedly measures the user's biological information and sets the air conditioning pattern based on the measured biological information every predetermined period. This predetermined period is, for example, the total of the predetermined time in step S23 and the measurement time of the user's biological information in step S24. On the other hand, if the air conditioning control unit 41 is turned off (step S29: YES), the basic control ends.

According to the present embodiment, the following effects can be obtained.
(1) The first air blowing mechanism 21, the second air blowing mechanism 22, and the heater 32 are used to air-condition (heat) the portion (buttock) that contacts the user when the user sits on the chair 1, and the portion that the user contacts. Since air conditioning (air blowing) is performed on the user's body part (for example, the posterior cervical spine) that is separated from the user, the air conditioning can be controlled for the individual user. Therefore, air conditioning suitable for the individual user can be supplied to the user. And the comfort to a user can be improved by controlling the heating to a user like the heater 32 and the ventilation to users like the air blowing mechanisms 21 and 22.

According to this configuration, air conditioning suitable for the individual user can be supplied to the user based on the user's biological information.

  (4) In the standby mode, the first blower 23, the second blower 26, and the heater 32 are driven based on a drive program stored in advance. According to this configuration, for example, power is supplied to the control device 40, and the first blower 23, the second blower 26, and the heater 32 are driven after the detection unit 30 detects the biological information of the user. The first blower 23, the second blower 26, and the heater 32 are driven quickly. For this reason, the air conditioning suitable for the individual user can be promptly supplied after the user starts using the control device 40. More specifically, the first blower 23 and the second blower 26 can quickly supply air to the user, and the heater 32 can quickly warm the user.

  (5) Since the storage unit 42 stores the control content changed by the user, the air conditioning control unit 41 can learn the control content changed by the user.

  (7) The chair 1 has the first blower 23 and the first wind direction part 25, and the second blower 26 and the second wind direction part 28 individually, so that the wind blown toward the user's neck and the user's waist The wind blown toward the can be set individually. Therefore, for example, when wind is blown simultaneously on the user's neck and waist, the average wind speed suitable for blowing on the user's neck can be discharged from the first wind direction portion 25, and blown on the user's waist. A wind having a suitable average wind speed can be discharged from the second wind direction portion 28.

  (8) Since the first blower 23 and the second blower 26 are provided below the seat portion 10, the first blower 23 and the second blower 26 are installed away from the user's ear when the user is seated. Is done. Therefore, it becomes difficult for the driving sound and wind noise of the first blower 23 and the second blower 26 to reach the user.
