Description

  The present invention relates to an air circulation type bedding that circulates air whose temperature is adjusted by a temperature adjustment unit to adjust the temperature in the bedding.

  When taking a break in a vehicle such as a truck, the room temperature in the vehicle often becomes high in the summer, and thus the air conditioner of the vehicle itself is operated to take a break while cooling the inside of the vehicle. However, since the engine continues to run only to move the air conditioner, there is a problem that not only wastes energy but also causes environmental pollution such as air pollution and noise pollution.

  Therefore, conventionally, the apparatus has a bedding main body having a space in which a person lies and an air conditioner connected to the bedding main body, and blows cool air generated by a cold heat source such as a refrigerator provided in the air conditioner. Has been proposed (see, for example, Patent Document 1).

  However, in such a bedding, even if it enters a bedding that has been cooled in summer, the body is exposed to high temperatures from outside and becomes hot. Even in the winter, the body and the bedding itself are cold, so there is a risk that even if they enter the bedding, they cannot immediately fall asleep comfortably.

These switches 26 a, 26 b, 26 c, 26 d, and 26 e are output an operation signal and input to the control unit 58 only during the pressing operation. In addition, the operation unit 26 is provided with a display unit 28 for displaying an operation state such as ON / OFF of the air circulation bedding 1 and a space in which the bedding main body 10 is installed, that is, a temperature in the vehicle 2. An external temperature sensor 57 for detecting (room temperature) is incorporated.

  The control unit 58 is disposed, for example, above the machine room 25 and includes a microcomputer. As shown in FIG. 10, in addition to the operation signal from the operation unit 26 described above, the control unit 58 includes a microcomputer. An engine stop signal for detecting engine stop is input from the engine control unit 59, and a temperature detection signal for detecting the temperature of the air that circulates and returns through the air flow path 11 of the bedding body 10 is input from the temperature sensor 39. A heating temperature signal for detecting the temperature of the heating device 70 is input from the temperature sensor 56, and an external temperature detection signal for detecting the temperature in the vehicle 2 is input from the external temperature sensor 57.

  The control unit 58 outputs the drive control signal to the drive unit 62 based on the input of the above various signals and the control program stored in the memory 60, whereby the compressor 31 included in the display unit 28 and the refrigeration cycle 30. The four-way valve 32, the blower fan 37, and the heat radiating fan 38 are driven and controlled. In addition, the control unit 58 controls the power supplied from the power supply unit 64 to the heating element 73 of the heating device 70 by inputting a power supply signal to the power supply unit 64.

  Then, when the cooling operation is selected by pressing the cooling / heating switch 26b in the operating state of the temperature adjustment unit 20, the cooling initial stage for controlling the refrigeration cycle 30 so that the temperature detected by the temperature sensor 39 coincides with the initial temperature. A control operation is performed, and then a cooling operation is performed to control the refrigeration cycle 30 so that the temperature detected by the temperature sensor 39 matches the set temperature.

  Specifically, as shown in FIG. 11, in step S <b> 1, the control unit 58 determines that the temperature setting of the bedding main body 10 is “strong”, “medium”, “ Which one of “weak” is set is read from the memory 60, and the process proceeds to step S2.

  As an example, in this embodiment, the controller 58 sets the temperature setting switch 26c to 24 ° C. when “strong” is selected, 26 ° C. when “medium” is selected, and 28 ° C. when “weak” is selected. The temperature (set temperature) of the air circulating in the air flow path 11 of the bedding body 10 is determined.

  In step S1, when the temperature setting switch 26c is pressed when the temperature adjustment unit 20 is activated, the operating condition corresponding to the pressed switch is read instead of the previous operating condition read from the memory 60.

  In step S2, the control unit 58 sets the initial temperature to a temperature 3 ° C. lower than the set temperature set in step S1, and adjusts the temperature of the air circulating in the air flow path 11 of the bedding main body 10 to the initial temperature. Perform control operation.

  Next, in step S3, it is determined whether or not a predetermined time (for example, 5 minutes in the present embodiment) has elapsed since the start of the cooling initial control operation. If the predetermined time has elapsed, the process proceeds to step S4 and has elapsed. If not, step S3 is repeated, and the control unit 58 controls the refrigeration cycle 30 so that the temperature detected by the temperature sensor 39 matches the initial temperature set as described above, and circulates through the air flow path 11 of the bedding body 10. The cooling initial control operation for adjusting the temperature of the air to the initial temperature is performed for a predetermined time.

  Next, in step S4, the control unit 58 controls the refrigeration cycle 30 so that the temperature detected by the temperature sensor 39 matches the set temperature set in step S1, and the temperature of the air circulating through the air flow path 11 of the bedding body 10 is determined. The cooling operation is performed to adjust the temperature to the set temperature, and the control unit 58 ends the cooling initial control operation.

  In addition, when the temperature control switch 26d is pressed during the cooling operation, the control unit 58 performs in-vehicle temperature control for adjusting the amount of air blown to the air flow path 11 in accordance with the temperature in the vehicle.

  Specifically, if the temperature inside the vehicle 2 detected by the external temperature sensor 57 built in the operation unit 26 is equal to or higher than a predetermined temperature (for example, the temperature detected by the external temperature sensor 57 is set in the above step S1). If the temperature is higher than the set temperature by 5 ° C. or more), the rotational speed of the blower fan 37 is set to be larger than that during normal cooling operation for a predetermined time (in this embodiment, for example, 5 minutes), and circulates through the air flow path 11 of the bedding main body 10. Set the air flow rate higher than during normal control operation. Then, after a predetermined time has elapsed, the rotational speed of the blower fan 37 is reduced, and the flow rate of air circulating through the air flow path 11 is reduced to the flow rate during normal control operation.

  On the other hand, when the heating operation is selected by pressing the cooling / heating switch 26b in the operation state of the temperature control unit 20, the control unit 58 drives the heating device 70 to set the heating value of the heating device 70 to a predetermined amount ( The heating initial control operation set to (initial heat generation amount) is performed for a predetermined time (in this embodiment, for example, 5 minutes), and then the heating operation is performed to set the heat generation amount of the heating device 70 to a heat generation amount smaller than the initial heat generation amount.

  In addition, when the temperature control switch 26d is pressed during the heating operation described above, the control unit 58 performs in-vehicle temperature control for controlling the rotation of the blower fan 37 in accordance with the temperature in the vehicle 2.

  Specifically, as shown in FIG. 12, in step S11, it is determined whether or not the temperature in the vehicle 2 detected by the external temperature sensor 57 built in the operation unit 26 is equal to or lower than a predetermined temperature. If so, the process proceeds to step S12. If the temperature is higher than the predetermined temperature, the interior temperature control is terminated and the heating operation is performed.

  In step S12, it is determined whether or not the temperature of the bedding body 10 detected by the heating temperature sensor 56 is equal to or higher than a predetermined temperature. If the temperature is equal to or higher than the predetermined temperature, the process proceeds to step S13. To do.

  In step S13, assuming that the heating device 70 has reached a predetermined temperature or more and has been sufficiently warmed up, the control unit 58 supplies power to the heating device 70 and rotates the blower fan 37 in a state where the heating device 70 generates heat to rotate the air flow path. Air is circulated in the air 11. Thereby, the air heated by the heating device 70 circulates in the air flow path 11, and the bedding main body 10 can be heated.

  Further, in the air circulation type bedding 1 of the present embodiment, when the timer switch 26e is pressed during the operation of the temperature adjustment unit 20, the control unit 58 starts a timer control operation.

  Specifically, as shown in the flowchart of FIG. 13, in step S21, the control unit 58 stops the temperature adjustment unit 20 after a lapse of time associated with the timer switch 26e that has been pressed from the time of pressing. Set the time (stop time).

  For example, when the timer switch 26e of “6” is pressed, the control unit 58 sets a stop time 6 hours after the timer switch 26e is pressed, and similarly, “4” and “2”. When the timer switch 26e is pressed, the control unit 58 sets stop times 4 hours and 2 hours after the timer switch 26e is pressed.

  In addition to the setting of the stop time, the control unit 58 sets a predetermined time (end control start time) before the stop time that is a predetermined time (for example, 10 minutes in the present embodiment) before the stop time, and step S22. Proceed to

  In step S22, it is determined whether or not the end control start time set in step S21 has elapsed. If the end control start time has elapsed, the process proceeds to step S23, and if the end control start time has not elapsed, step S22 is repeated to perform the above-described cooling operation or heating operation.

  In step S23, the control unit 58 determines whether the cooling operation or the heating operation is being performed. If the cooling operation is being performed, the process proceeds to step S24, and if the heating operation is being performed, step S25 is performed. Proceed to

  In step S24, the control unit 58 gradually increases the detected temperature of the temperature sensor 39 from the set temperature to the ambient temperature (external temperature) of the place where the bedding body 10 is installed from the end control start time set in step S21 to the stop time. The refrigeration cycle 30 is controlled so as to approach, and an end control operation is performed in which the temperature of the air circulating in the air flow path 11 of the bedding main body 10 gradually approaches the set temperature to the external temperature of the bedding main body 10, and ends after the stop time has elapsed. When the control operation ends, the process proceeds to step S26.

  In step S25, the control unit 58 performs an end control operation for controlling the amount of heat generated by the heating device 70 to gradually decrease from the end control start time set in step S21 to the stop time, and the stop time has elapsed. When the end control operation ends, the process proceeds to step S26.

  In step S26, the controller 58 stops the temperature adjustment unit 20 and ends the timer control operation.

  Further, when the temperature detected by the temperature sensor 39 changes during the operation of the temperature adjustment unit 20 by a predetermined temperature (for example, 5 ° C.) or more within a predetermined time (for example, 10 seconds), the control unit 58 Assuming that the air in the vehicle 2 has been introduced into the temperature control chamber 27 from the suction duct 24 due to reasons such as the suction duct 24 being dropped from the bedding main body 10, an error is displayed on the display unit 28 to notify the abnormality. Do. The control unit 58 may output a warning sound instead of the error display or in combination with the error display when the blowout duct 22 or the suction duct 24 falls off the bedding main body 10.

  As described above, in the air circulation type bedding 1 of the present embodiment, in order to perform the cooling initial control operation for circulating the air set at a temperature lower than the set temperature for a predetermined time from the start of the cooling operation in the air flow path 11. The coolness of the bedding body 10 can be emphasized, and even a body that has been exposed to high temperatures and becomes hot can comfortably fall asleep. In addition, when the cooling initial control operation is executed for a predetermined time, the temperature of the air circulating in the air flow path 11 is increased from the initial temperature to the set temperature and the normal cooling operation is shifted, so that the user A may be overcooled. Absent.

  In addition, the heating value of the heating device 70 is set to the initial heating value for a predetermined time from the start of the heating operation, and then the heating value of the heating device 70 is set to a heating value smaller than the initial heating value. The warmth can be emphasized, and even a cold body exposed to the outside air in winter can sleep comfortably. In addition, when the heating initial control operation is executed for a predetermined time, the amount of heat generated by the heating device 70 is reduced and the normal heating operation is performed, so that the user A does not feel hot and sleepy.

  Further, in the air circulation type bedding 1 of the present embodiment, when the temperature in the vehicle 2 detected by the external temperature sensor 57 during the cooling operation is equal to or higher than a predetermined temperature, the blower fan 37 rotates from the normal cooling operation. The amount of air blown to the air flow path 11 is adjusted according to the temperature in the vehicle 2 by setting a large number and increasing the flow rate of air circulating through the air flow path 11 of the bedding main body 10 from that during normal control operation. The bedding body 10 can be cooled with appropriate driving strength, and a comfortable sleeping environment can be obtained.

  Moreover, in the air circulation type bedding 1 of this embodiment, since the said ventilation fan can be driven, supplying a power supply to a heating device at the time of heating operation, the heat from the heating device 70 is moved to the bedding main body 10. Can do.

  In addition, since the air blowing fan 37 is driven to rotate and the air is circulated in the air passage 11 after the temperature detected by the heating temperature sensor 56 reaches a predetermined temperature or more, cold air is circulated in the air passage 11 during the heating operation. There is no circulation. Moreover, since the heating device 70 is embedded in the foot accommodating portion 10b and the opening 12 for connecting the blowout duct 22 is provided, the control unit 58 rotates the blower fan 37 while supplying power to the heating device 70. By driving and circulating air in the air flow path 11, heat from the heating device 70 that warms the foot accommodating portion 10b can be moved to the trunk accommodating portion 10a. Thereby, an appropriate temperature gradient can be provided in the bedding main body 10 so that the temperature gradually decreases from the foot accommodating portion 10b toward the trunk accommodating portion 10a, and a comfortable sleeping environment can be obtained.

  Further, in the air circulation type bedding 1 of the present embodiment, air that circulates through the air flow path 11 of the bedding main body 10 during the cooling operation from the end control start time set before the stop time to the stop time. The temperature of the heater is gradually brought closer to the external temperature of the bedding main body 10 from the set temperature, and during the heating operation, the end control operation for controlling the heating device 70 so as to gradually decrease the heat generation amount is performed, so the operation is stopped by the timer control operation. Even if the temperature adjustment unit 20 stops at the time, the temperature of the bedding body 10 does not change abruptly, and a comfortable awakening is possible.

  Moreover, in the air circulation type bedding 1 of this embodiment, since the control part 58 alert | reports abnormality when the blowing duct 22 or the suction duct 24 drops | omits from the bedding main body 10, it will drop the ducts 22 and 24 to the user A promptly. I can let you know.

  In particular, when the air in the vehicle 2 is introduced into the temperature control chamber 27 from the suction duct 24 due to reasons such as the suction duct 24 being dropped from the bedding main body 10, the detected temperature and set temperature of the temperature sensor 39 The deviation becomes larger.
