JP 2005-138640 A

  However, in the in-vehicle drying device described in Patent Document 1, the air blown from the air conditioner is merely introduced into the tent. For this reason, the amount of drying of the object to be dried largely depends on the air-conditioning control state in the passenger compartment, and there is a problem that the drying efficiency of the object to be dried is extremely inferior.

  The subject of this invention is providing the vehicle-mounted drying apparatus with favorable drying efficiency of a drying target object.

Means for Solving the Problems and Effects of the Invention

  In order to solve the above problems, an in-vehicle drying apparatus of the present invention includes a drying chamber connected to a duct of an air conditioner unit through a communication path, and an operating unit for operating on or off the drying function of the drying chamber, The amount of blown air blown into the drying chamber according to the temperature of the drying chamber detected by the temperature sensor on condition that the temperature sensor for detecting the temperature in the drying chamber and the operation of the drying function of the drying chamber by the operating means are turned on And control means for controlling the temperature of the blown air.

  According to this, on the condition that the drying function of the drying chamber is turned on by the operation means, the amount of blown air blown into the drying chamber and the blowing air according to the room temperature of the drying chamber detected by the temperature sensor by the control means The temperature is controlled. For this reason, when the amount of blown air blown into the drying chamber and the temperature of the blown air are set to the optimum conditions for drying the object to be dried, the drying time of the object to be dried can be shortened. It is possible to improve the drying efficiency of the object to be dried.

  In carrying out the present invention, the control means performs a heating process for setting the blown air volume of the blown air into the drying chamber to a predetermined high air volume and setting the blown air temperature to a predetermined high temperature, and the detected drying chamber It is preferable that the cooling process for setting the blown air temperature to a predetermined low temperature is performed in a state in which the blown air volume is maintained at a high air volume, on the condition that the indoor temperature is higher than the target room temperature. In this case, for example, when the detected room temperature of the drying chamber becomes higher than the target room temperature, the control means performs a predetermined drying process for setting the blowing air temperature to the target room temperature while maintaining the blowing air volume at a high air volume. It is preferable that the drying process is executed and the cooling process is executed after the drying process. In addition, the control means, for example, executes the cooling process until a room temperature of the drying chamber becomes approximately the same as the vehicle interior temperature after executing the cooling process for a predetermined cooling time. Preferably, the drying function is turned off.

  According to this, after the drying function of the drying chamber is turned on by the operation of the operation means by the user, the heating is automatically performed by the control means unless the drying function of the drying chamber is turned off by the operation of the operation means. Processing is performed, and then cooling processing is performed. Therefore, a special operation for drying the object to be dried by the user becomes unnecessary, and the operation burden on the user can be reduced well.

  Further, when carrying out the present invention, the operation means is provided with an alarm display portion which is turned on after the drying function of the drying chamber is started, and which is turned off when the room temperature of the drying chamber becomes approximately the same as the vehicle interior temperature. It is good to have. According to this, it is possible to alert the user not to open the drying chamber by turning on the alarm display section, and it is possible to ensure good safety when the drying function of the drying chamber is in an operating state. .

FIG. 1 is a block diagram schematically showing an embodiment of an in-vehicle drying apparatus of the present invention. This in-vehicle drying device is for drying an object to be dried in the drying chamber 40 using cool and warm air generated by the air conditioner unit AU.

  The air conditioner unit AU includes a duct 10 as is well known. The duct 10 is formed with an inside air inlet 11 for circulating the air inside the vehicle and an outside air inlet 12 for introducing air outside the vehicle. The inside air inlet 11 and the outside air inlet 12 are switched by an inside / outside air switching damper 13. The inside / outside air switching damper 13 is opened and closed by an inside / outside air switching servo motor 31. Air from the inside air inlet 11 or the outside air inlet 12 is sucked into the duct 10 by a blower 21 driven by a blower motor 32.

  An evaporator 22 for cooling the sucked air to generate cool air and a heater core 23 for heating the sucked air to generate warm air are provided in the duct 10. The cool air and the warm air are mixed at a ratio corresponding to the angular position of the air mix damper 14 and blown out from the respective outlets 15a to 15c. The air mix damper 14 is opened and closed by an air mix servomotor 33.

  The blower outlet 15a opens, for example, in the upper rear of the instrument panel corresponding to the lower inner edge of the front glass, the blower outlet 15b opens in the center of the front of the instrument panel, and the blower outlet 15c opens in the communication passage 16, respectively. -19 to open and close. The blower outlet switching dampers 17 to 19 are in a state where only the blower outlet 15a is opened by the damper drive gear mechanism 24 according to the rotational input phase for damper control from the blower outlet switching servomotor 34, and only the blower outlet 15b. Is opened / closed so as to be in any one of a state in which the air outlet 15c is open, a state in which only the air outlet 15c is open, and a state in which the air outlets 15a and 15b are open.

  The drying chamber 40 includes a main body portion 41 and a lid portion 42 that is rotatably attached to the main body portion 41, such as an in-vehicle refrigerated storage cabinet or a dedicated drying chamber. The inside of the main body portion 41 is configured to be a substantially closed space with the lid portion 42 closed. Air blown from the duct 10 of the air conditioner unit AU is introduced into the drying chamber 40 through the communication passage 16 provided on the downstream side of the heater core 23. The introduced blowing air is discharged outside the vehicle through the exhaust passage 43.

  The inside / outside air switching servo motor 31, blower motor 32, air mix servo motor 33, and outlet switching servo motor 34 are driven and controlled by a microcomputer 51 (hereinafter simply referred to as a microcomputer 51) of an air conditioner ECU.

  The microcomputer 51 includes a CPU, ROM, RAM, input / output circuit, and the like as main components, and executes the drying control program of FIG. 3 stored in the ROM or the like in response to a switch operation of the operation panel 60. A temperature sensor 52 and an operation panel 60 are connected to the microcomputer 51.

  The temperature sensor 52 detects the room temperature of the drying chamber 40 and outputs it to the microcomputer 51. The operation panel 60 (operation means) is provided on, for example, an instrument panel, and includes an operation changeover switch 61, an operation display unit 62, and an alarm display unit 63 as shown in FIG. The operation changeover switch 61 is turned on or off by a user operation. As will be described later, the operation indicator 62 is lit when the operation mode of the drying function is on, that is, when the operation mode is “HOT” (heating), “DRY” (drying), or “COOL” (cooling). When the function processing is completed, that is, when the processing from the switch state being turned on by the operation of the operation changeover switch 61 to the cooling processing is completed, the light is turned off. The alarm display unit 63 is lit from the start of the drying function process to the end of the cooling standby process, and when the room temperature of the drying room becomes sufficiently low, that is, the room temperature of the drying room is about the same as the vehicle room temperature. When it becomes, it is turned off.

  Next, the operation of the present embodiment configured as described above will be described. The microcomputer 51 repeatedly executes the drying control program of FIG. 3 stored in the ROM or the like.

  The drying control program is started in step S10, and when the switch state is turned on by operating the operation changeover switch 61, it is determined to be on in step 11, and the processing from step S12 is performed. Execute. When the operation changeover switch 61 is not operated and the switch state is kept off, it is determined that the switch is off in step 11, “Yes” is determined in step S 39, and this is determined in step S 40. The execution of the drying control program is terminated.

In step S12, it is determined whether or not the operation mode of the drying function of the drying chamber 40 is off.
The operation mode of the drying chamber 40 is set to be turned on only when an operation mode described later is set to “HOT”. Therefore, at this stage, it is determined as “Yes” in Step S12, and the processes after Step S13 are executed.

  In step S13, the blower outlet switching process is performed so that the blower outlets 15a and 15b are closed by the blower switching dampers 17 and 18 and the blower outlet 15c is opened by the blower switching damper 19. The motor 34 is driven. Next, in step S14, the operation display unit 62 of the operation panel 60 is turned on (lighted). In step S15, the alarm display part 63 of the operation panel 60 is turned on (lighted). In step S <b> 16, the blower motor 32 is driven so that the amount of blown air blown into the drying chamber 40 becomes “MAX”.

  In step S17, the air mixing servo motor 33 is driven to bring the air mix damper 14 to a predetermined angular position so that the drying function is in the operation mode “HOT”, that is, the room temperature of the drying room 40 is equal to or higher than the target room temperature. Set. In step S18, the blown air temperature of the blown air into the drying chamber 40 is set to “heating temperature”. The heating temperature is set to a high temperature (for example, 70 ° C.) that can raise the room temperature of the drying chamber 40 in a short time.

  After the process of step S18, execution of this drying control program is once complete | finished in step S40. At the next execution of this drying control program, the switch state is turned on in step S11, “No” in step S12 (the drying function is set to the operation mode “HOT”), and “Yes” in step S19. In step S20, it is determined whether or not the room temperature of the drying chamber 40 detected by the temperature sensor 52 is equal to or higher than a predetermined target room temperature.

  The target room temperature is set to a predetermined high temperature (for example, 60 ° C.) that increases the temperature of the drying object in the drying chamber 40 to promote the increase in the amount of water vapor emitted from the drying object and suppresses condensation of the water vapor. Has been. Since the room temperature of the drying chamber 40 does not reach the target temperature in the normal state, it is determined as “No” in Step S20, and the processes after Step S13 are executed. Thereafter, the processes of steps S10 to S12, S19, S20, S13 to S18, and S40 are repeatedly executed until the room temperature of the drying chamber 40 becomes equal to or higher than the target room temperature.

  If the room temperature of the drying chamber 40 is equal to or higher than the target room temperature, “Yes” is determined in step S20, and the processes in and after step S21 are executed. In step S21, similarly to the process of step S16, the blower motor 32 is driven so that the amount of the blown air blown into the drying chamber 40 becomes the maximum “MAX”. In step S22, the air mix servo motor 33 is driven to set the air mix damper 14 at a predetermined angle so that the drying function is in the operation mode “DRY”, that is, the room temperature of the drying room 40 is stabilized near the target room temperature. Set to position. In step S23, the blowing air temperature of the blowing air into the drying chamber 40 is set to the target room temperature described above.

  After the process of step S23, the execution of this drying control program is once ended in step S40. At the next execution of the drying control program, the switch state is turned on in step S11, “No” is set in step S12 (the drying function is set to the operation mode “DRY”), and “No” is set in step S19. ”And timer count processing is executed in step S24.

  Next, since the drying function is set to the operation mode “DRY”, “Yes” is determined in step S25, and whether or not the timer value T has passed the predetermined DRY mode standby time T1 in step S26. judge. The DRY mode standby time T1 (drying time) is set to a length that allows the drying target in the drying chamber 40 to be sufficiently dried. At the time of the first execution of step S26, since the waiting time T1 has not yet elapsed, it is determined as “No” in step S26, and the processes after step S21 are executed.

  Until the timer value T has passed the predetermined DRY mode standby time T1, the processes of steps S10 to S12, S19, S24 to S26, S21 to S23, and S40 are repeatedly executed, and the operation mode of the drying function is in the “DRY” state. Maintained. By maintaining the operation mode “DRY” state, the water vapor in the drying chamber 40 is well removed to the outside of the vehicle compartment through the exhaust passage 43, and the drying proceeds with the divergence of the object to be dried being dominant.

  If the timer value T has exceeded the predetermined DRY mode standby time T1, it is determined as “Yes” in step S26, and the processing from step S27 is executed. In step S27, similarly to the processing in steps S16 and S21, the blower motor 32 is driven so that the amount of blown air blown into the drying chamber 40 becomes the maximum “MAX”. In step S28, the air mixing servo motor 33 is driven to bring the air mix damper 14 to a predetermined angular position so that the drying function is in the operation mode “COOL”, that is, the room temperature of the drying chamber 40 is equal to or lower than the target room temperature. Set. In step S29, the blown air temperature of the blown air into the drying chamber 40 is set to “cooling temperature”. The cooling temperature is set to a low temperature (for example, 10 ° C.) that can lower the room temperature of the drying chamber 40 to a target room temperature or less in a short time.

  After the process of step S29, the execution of this drying control program is once ended in step S40. At the next execution of the drying control program, the switch state is turned on in step S11, “No” is set in step S12 (the drying function is set to the operation mode “COOL”), and “No” is set in step S19. ”And timer count processing is executed in step S24.

  Next, since the drying function is set to the operation mode “COOL”, it is determined as “No” in Step S25, and it is determined whether or not the timer value T has passed a predetermined COOL mode standby time T2 in Step S30. judge. The COOL mode standby time T2 (cooling time) is set to a length at which the object to be dried in the drying chamber 40 is sufficiently dried and has a low temperature. At the time of the first execution of step S30, since the waiting time T2 has not yet elapsed, it is determined as “No” in step S30, and the processing after step S27 is executed.

  Thereafter, until the timer value T has passed the COOL mode standby time T2, the processes of steps S10 to S12, S19, S24, S25, S30, S27 to 29, and S40 are repeatedly executed, and the operation mode of the drying function is “COOL. Is maintained.

  When the timer value T has passed the COOL mode standby time T2, it is determined as “Yes” in step S30, and the processing after step S31 is executed. In step S31, the operation display unit 62 of the operation panel 60 is turned off (extinguished). Next, in step S32, it is determined whether or not the room temperature of the drying chamber 40 has dropped to the vicinity of the vehicle interior temperature (for example, whether the room temperature of the drying chamber 40 has become (vehicle interior temperature + 3 ° C.) or less). . This is because it is considered appropriate to shift the operation mode to OFF when the temperature of the drying chamber 40 is sufficiently lowered. At the time of the first execution of step S32, since the room temperature of the drying room 40 has not yet reached the vicinity of the vehicle interior temperature, it is determined as “No” in step S32, and the processes after step S27 are executed.

  Thereafter, until the indoor temperature of the drying chamber 40 reaches the vicinity of the vehicle interior temperature, the processes of steps S10 to S12, S19, S24, S25, S30 to S32, S27 to 29, and S40 are repeatedly executed to operate the drying function. The mode is maintained in a standby state with “COOL”.

  If the room temperature of the drying chamber 40 has reached the temperature in the vicinity of the passenger compartment, “Yes” is determined in step S32, and the processes in and after step S33 are executed. In step S33, the alarm display part 63 of the operation panel 60 is turned off (extinguished). In step S <b> 34, the blower motor 32 is driven so that the blown air volume of the blown air into the drying chamber 40 returns to the air volume during the air conditioning process. In step S35, the operation mode of the drying function is set to “off”. In step S36, the temperature of the blown air blown into the drying chamber 40 is set to the “air condition temperature” during the air conditioning process.

  Next, in step S37, the air outlet damper return process, that is, the air outlets 15a and 15b are opened by the air outlet switching dampers 17 and 18, and the air outlet 15c is closed by the air outlet switching damper 19. The switching servo motor 34 is driven. In step S38, the timer value T is cleared. After step S38, the execution of this drying control program is terminated in step S40.

  When the operation mode is “HOT”, “DRY”, or “COOL” and the switch state is turned off by the operation of the operation changeover switch 61, it is determined to be off in step S11. In S39, “No” is determined, and the processing after step S31 is executed. In this case, if the room temperature in drying chamber 40 is higher than the temperature in the vicinity of the passenger compartment (“No” in step S32), the operation mode “COOL” process from step S27 is executed. When it is determined by execution of the operation mode “COOL” process or at the time of determination in step S32 that the room temperature of the drying chamber 40 is the vehicle interior vicinity temperature (“Yes” in step S32), step S33 and subsequent steps. The operation mode “OFF” process is executed.

  As is clear from the above description, in this embodiment, the interior of the drying chamber 40 detected by the temperature sensor 52 on condition that the drying function of the drying chamber 40 is turned on by the operation panel 60 (ON in step S11). Depending on the temperature (step S20), the amount of blown air blown into the drying chamber 40 and the temperature of the blown air satisfy the optimum conditions for drying the object to be dried (steps S16 to S18, S21 to S23, S27 to S29). To be controlled.

  Thereby, it becomes possible to shorten the drying time of a drying target object, and it is possible to improve the drying efficiency of a drying target object.

  Moreover, in the said embodiment, the heat processing (step S16-S18) which sets the blowing air volume of the blowing wind in the drying chamber 40 to predetermined high air volume and sets blowing air temperature to predetermined high temperature are performed, On condition that the detected room temperature of the drying chamber 40 is higher than the target room temperature (“Yes” in step S20), the blown air temperature is set to a predetermined low temperature while the blown air volume is maintained at a high air volume. The cooling process to be set (steps S27 to S29) is executed.

  In particular, in this embodiment, when the detected indoor temperature of the drying chamber 40 becomes higher than the target room temperature (“Yes” in step S20), the target blow air temperature is maintained in a state where the blow air flow is maintained at a high air flow. The drying process (steps S21 to S23) set to room temperature is executed until a predetermined DRY mode standby time T1 has elapsed, and after the drying process is executed (“Yes” in step S26), the cooling process (steps S27 to S29) is performed. Is executed. Further, after the cooling process is executed until a predetermined COOL mode standby time T2 has elapsed (“Yes” in step S30), the room temperature of the drying chamber 40 is kept in the vehicle interior with the blowing air temperature maintained at a low temperature. The cooling standby process (steps S27 to S29 until “Yes” is determined in step S32) is executed until the temperature reaches the vicinity, and after the cooling standby process is executed (“Yes” in step S32), the drying chamber 40 drying functions are turned off (step S35).

  Thereby, after the drying function of the drying chamber 40 is turned on by the operation of the operation changeover switch 61 by the user (ON in step S11), the drying function of the drying chamber 40 is turned off by the operation of the operation changeover switch 61. Unless otherwise (OFF in step S11), the heating process, the drying process, the cooling process, and the cooling standby process are sequentially automatically executed. Therefore, a special operation for drying the object to be dried by the user is not required, and the operation burden on the user is extremely well reduced.

  In the above embodiment, the operation panel 60 is turned on from the start of the drying function of the drying chamber 40, and is turned off when the indoor temperature of the drying chamber 40 becomes approximately equal to the vehicle interior temperature. Is provided.

Thereby, it is possible to alert the user not to open the drying chamber 40 by turning on the alarm display section 63, and to ensure good safety when the drying function of the drying chamber 40 is in an operating state. it can.
