Description

  The present invention relates to setting of a reference value of an odor sensor in a deodorizing apparatus.

  Conventionally, as a device for cleaning air, a sensor for detecting the air quality in the room is used, and the air quality level in the room is evaluated by comparing a preset reference level with the air quality level detected by the sensor. An apparatus for purifying indoor air when the air quality is poor is known (for example, see Patent Document 1). In addition, as an example of such a device, an odor sensor that detects indoor odor components is used as a sensor, and indoor air is deodorized using a deodorizing filter that removes odor components when the indoor air quality is poor. Deodorizing devices are known.

  In such a deodorizing device, during the deodorizing operation, a reference level for determining the necessity of deodorizing air set in advance is compared with a detection level detected by the odor sensor, and the detection level is the reference level. If it is above, there exists what performs automatic driving | operation control by which driving | running air volume is changed according to the difference of a detection level and a reference level.

  Therefore, in this deodorizing apparatus, if the reference level does not correspond to the indoor environment where the deodorizing apparatus is installed, there is a possibility that appropriate automatic operation control cannot be performed. For this reason, the deodorizing apparatus which can set the reference | standard level according to the indoor environment where the deodorizing apparatus was installed was required so that automatic operation control of a deodorizing apparatus might be performed appropriately. Also, since the detection sensitivity of the odor sensor changes due to aging and variations in the odor sensor itself, there is a possibility that appropriate automatic operation control cannot be performed if the reference level does not correspond to the detection sensitivity of the odor sensor. For this reason, the deodorizing apparatus which can set the reference level according to the detection sensitivity of an odor sensor was needed.

A rotation motor drive unit 49 and a control means 40 for controlling them are provided.

  The power supply unit 41 is connected to an outlet via a power cord 48, generates a DC voltage necessary for operation of the deodorizing apparatus 1 from an AC voltage supplied via the outlet, and generates an ion generator 22, a control means 40, The power is supplied to the switch unit 43, the fan motor drive unit 45, the heater energization unit 46, the switching plate rotation motor drive unit 47, and the louver rotation motor drive unit 49. In FIG. 4, power supply from the power supply unit 41 to the ion generator 22, the control unit 40, and the switch unit 43 is indicated by arrows, but the other power supply arrows are not illustrated. The remote control receiving unit 42 receives a signal transmitted from a remote controller (not shown) for operating the deodorizing apparatus 1.

  The switch unit 43 turns on and off the DC voltage supplied from the power supply unit 41 based on a signal from the control unit 40, and the inverter 44 converts the DC voltage received from the switch unit 43 into a high-frequency voltage that can turn on the UV lamp 21b. And supplied to the UV lamp 21b. The ion generator 22 has a power supply circuit (not shown) inside, and adds a DC voltage supplied from the power supply unit 41 between the discharge electrode and the ground electrode to generate a corona discharge between the two electrodes.

Each of the fan motor drive unit 45, the heater energization unit 46, the switching plate rotation motor drive unit 47, and the louver rotation motor drive unit 49 receives the DC voltage supplied from the power supply unit 41, and receives the fan motor 20a and heater. 30b, the switching plate rotating motor 57 and the louver rotating motor 16a are driven.

  The control means 40 includes a microcomputer having a timer (not shown) and a storage unit 40a. The microcomputer receives a driving instruction signal from the user from the remote control receiving unit 42 and the operation unit 24 arranged on the upper panel 15 of the deodorizing apparatus 1 and takes in a detection signal from the odor sensor 51. Further, the microcomputer controls the energization to the UV lamp 21b by transmitting an on / off signal to the switch unit 43 based on the operation instruction signal and the detection signal described above, and the fan motor drive unit 45 and the heater energization unit 46. The control signals corresponding to the switching plate rotation motor drive unit 47 and the louver rotation motor drive unit 49 are transmitted to the fan motor 20a, the heater 30b, the switching plate rotation motor 57, and the louver rotation motor 16a, respectively. Drive control is performed. Further, the microcomputer performs drive control of the ion generator 22.

  Next, the function of each part and the flow of air inside the deodorizing apparatus 1 when performing the deodorizing operation with the deodorizing apparatus 1 will be described. When the user operates a remote controller (not shown) or the operation unit 24, an operation instruction signal for instructing the start of the deodorizing operation of the deodorizing apparatus 1 from the remote control receiving unit 42 or the operation unit 24 is transmitted from the remote control or the operation unit 24 to the control means 40. Sent to.

  The control means 40 that has received the operation instruction signal transmits a drive control signal including the rotational speed information of the fan motor 20a to the fan motor drive unit 45. The fan motor drive unit 45 activates the fan motor 20a based on the received drive control signal. Thereby, the ventilation fan 20b rotates and the air blower 20 starts an operation | movement. Moreover, the control means 40 transmits a drive control signal to the louver rotation motor drive section 49 in order to rotate the louver 16 and open the air outlet 15a. Based on the received drive control signal, the louver rotation motor drive unit 49 drives the louver rotation motor 16a so that the suction port 12a and the air outlet 15a communicate with each other, as shown in FIG.

  Next, the control means 40 transmits a drive control signal to the switching plate rotation motor drive unit 47 in order to detect the odor component of the room air. Based on the received drive control signal, the switching plate rotation motor drive unit 47 switches the switching plate rotation motor so that the indoor side detection hole 53 and the air outflow hole 55 communicate with each other as shown in FIG. 57 is driven to rotate the switching plate 56 toward the device inner side detection hole 54. Thereby, the odor sensor 51 can detect the odor component contained in room air.

  Next, the control unit 40 transmits an ON signal to the switch unit 43. The switch unit 43 that is turned on upon receiving the ON signal starts energization to the UV lamp 21b via the inverter unit 44, and turns on the UV lamp 21b. Further, the control means 40 transmits a drive signal to the ion generator 22 to drive the ion generator 22.

  When the blower 20 is operated in the state described above, room air is sucked into the deodorizing apparatus 1 from the suction port 12a. The air sucked from the suction port 12a is dedusted when passing through the dust collecting filter 31, and deodorized when passing through the deodorizing filter 30a. Next, the air that has passed through the dust collection filter 31 and the deodorizing filter 30 a is humidified when passing through the vaporization filter 32.

  The air that has passed through the vaporization filter 32 flows upward (downstream of the air flow path 10) in the air flow path 10, and most of the air is discharged into the room from the air outlet 15a. At that time, the negative ions generated by the ion generator 22 are released into the room on the air discharged from the outlet 15a into the room. The negative ions released into the room adhere to microorganisms such as mold and virus floating in the room and inactivate them. The low-concentration ozone generated by the ion generator 22 oxidizes odor components that could not be decomposed by the deodorizing filter 30a contained in the air that flows in the vicinity of the ion generator 22 and is discharged into the room from the outlet 15a. Decomposes on reaction.

  On the other hand, part of the air that has passed through the vaporization filter 32 is taken into the ozone generator 21 through the inlet 21d. The taken-in air is irradiated with ultraviolet rays by the UV lamp 21b, thereby generating ozone. The generated ozone sterilizes microorganisms such as mold and virus floating in the taken-in air, and decomposes odor components that could not be decomposed by the deodorizing filter 30a by an oxidation reaction.

  The air inside the ozone generator 21 that has been sterilized and deodorized is discharged into the room from the outlet 15a through the outlet 21e. The air released from the inside of the ozone generator 21 contains ozone having a low concentration due to the action of the ozone decomposition catalyst 21c, and this low concentration of ozone removes odorous components adhering to indoor carpets and curtains. Decompose.

  In the deodorizing apparatus 1 according to the present embodiment, the reference value of the odor sensor 51 for determining whether or not the indoor air needs to be deodorized is stored in the storage unit 40a provided inside the control means 40. The reference value of the odor sensor 51 is appropriately changed by the control means 40 according to the indoor environment and the detection sensitivity of the odor sensor 51. The control means 40 provided in the deodorizing apparatus 1 compares the detected value corresponding to the odor component of the indoor air detected by the odor sensor 51 with the reference value of the odor sensor 51 during the deodorizing operation. And as a result of the comparison, if the detected value is equal to or greater than the reference value, the control means 40 performs automatic operation control that changes the operating air volume according to the difference between the detected value and the reference value (proportional to the amount of odor component). . In the automatic operation control by the control means 40, the rotation speed of the fan motor 20b is controlled according to the operation air volume. In the automatic operation control by the control means 40, the operation start or operation stop of the ozone generator 21 or the ion generator 22 is controlled.

  Moreover, the deodorizing apparatus 1 heats the deodorizing filter 30a with the heater 30b, accelerates decomposition | disassembly by the catalyst of the odor component which the deodorizing filter 30a adsorb | sucked by the above-mentioned automatic operation control, and reproduces | regenerates deodorizing performance regularly. The control means 40 accumulates the time during which the deodorizing operation is performed by measuring with a timer, and stores the accumulated time in the storage unit 40a. When the accumulated time reaches a predetermined time t1 (for example, 24 hours), the control means 40 starts regeneration of the deodorizing performance of the deodorizing filter 30a. The control means 40 starts a timer from the start of regeneration of the deodorizing performance of the deodorizing filter 30a, stops the timer when a predetermined time t2 (for example, 1 hour) has elapsed, and ends the regeneration of the deodorizing performance of the deodorizing filter 30a. Note that the predetermined time t1 corresponding to the accumulated time is a time until the deodorizing ability obtained experimentally in advance is saturated, and is stored in the storage unit 40a. Further, a predetermined time t2 from the start of playback to the end of playback is also stored in advance in the storage unit 40a.

  The deodorizing apparatus 1 described above performs the setting of the reference value of the odor sensor 51 for determining whether or not the indoor air needs to be deodorized after the regeneration of the deodorizing performance of the deodorizing filter 30a is completed. Next, the reference value setting operation of the odor sensor 51 will be described in detail.

  The control means 40 energizes the heater 30b via the heater energization unit 46, and starts regeneration of the deodorizing performance of the deodorizing filter 30a. The control means 40 starts the operation of the ozone generator 21 and the ion generator 22 when the regeneration of the deodorizing performance of the deodorizing filter 30a is started. Furthermore, the control means 40 drives the louver rotation motor 16a via the louver rotation motor drive unit 49 simultaneously with the start of these. The louver 16 is rotated by driving the louver rotating motor 16a, and the air outlet 15a is closed. The control means 40 drives the switching plate rotating motor 57 via the switching plate rotating motor driving section 47 simultaneously with the driving of the louver rotating motor 16a. By driving the switching plate rotating motor 57, the switching plate 56 is rotated toward the indoor detection hole 53 side.

  The control means 40 starts a timer from the start of regeneration of the deodorizing performance of the deodorizing filter 30a, and stops the timer after a predetermined time t2. After stopping the timer, the control means 40 stops the energization to the heater 30b via the heater energization unit 46, and ends the regeneration of the deodorizing performance of the deodorizing filter 30a. The control means 40 stops the operation of the ozone generator 21 and the ion generator 22 when the regeneration of the deodorizing performance of the deodorizing filter 30a is completed. Furthermore, in order to set the reference value of the odor sensor 51, the control means 40 starts a timer from the end of regeneration of the deodorizing performance of the deodorizing filter 30a and waits until a predetermined time t3 (for example, 1 hour) elapses. Then stop the timer. After stopping the timer, the control means 40 takes in the detected value of the odor sensor 51 and stores this detected value in the storage unit 40a as a reference value. Note that the predetermined time t3 corresponding to the standby time is a time until the internal temperature heated by the heater 30b of the deodorizing apparatus 1 reaches a temperature equivalent to the room temperature, which is experimentally obtained in advance, and is stored in the storage unit 40a. It is remembered.

  When the regeneration of the deodorizing performance of the deodorizing filter 30a and the setting of the reference value of the odor sensor 51 are completed, the control means 40 starts the deodorizing operation via the switching plate rotating motor driving unit 47 to start the deodorizing operation. The driving motor 57 is driven. By driving the switching plate rotating motor 57, the switching plate 56 is rotated to the device inner side detection hole 54 side. Further, when the regeneration of the deodorizing performance of the deodorizing filter 30a and the setting of the reference value of the odor sensor 51 are completed, the control means 40 performs a louver rotation via the louver rotating motor driving unit 49 to start the deodorizing operation. The driving motor 16a is driven. The louver 16 is rotated by driving the louver rotating motor 16a to open the air outlet 15a. Then, the control means 40 compares the detection value detected by the odor sensor 51 with the reference value stored in the storage unit 40a after regenerating the deodorizing filter 30a, and if the detection value is equal to or greater than the reference value, The operating air volume is changed according to the difference from the reference value.

  According to the deodorizing device 1 described above, air is retained in the air flow path 10 in the deodorizing device 1 by rotating the louver 16 and closing the outlet 15a when the deodorizing filter 30a is regenerated. ing. Further, when the ozone generator 21 and the ion generator 22 are operated during the regeneration of the deodorizing filter 30a, the deodorizing filter 30a stays in the air flow paths 10 around the deodorizing filter 30a, the ozone generator 21, and the ion generator 22. It is designed to remove odorous components contained in the air. And after removing the odor component contained in the air staying in the air flow path 10 in the deodorizing apparatus 1, the odor sensor 51 in a state where the switching plate 56 is rotated to the indoor side detection hole 53 side is detected. The detected value is stored in the storage unit 40a as the reference value of the odor sensor 51.

  Therefore, since the reference value of the odor sensor 51 suitable for determining whether or not the air needs to be deodorized can be set according to the indoor environment in which the deodorizing apparatus 1 is installed, automatic operation control is performed with an appropriate operation air volume. be able to. For this reason, when the odor itself is removed from the room air by the deodorizing filter 30a or the like during the deodorizing operation of the deodorizing device 1, the odor sensor 51 stored in the storage unit 40a is below the reference value, and automatic operation control is appropriately performed. Can do.

  Further, in the deodorizing apparatus 1, after the deodorizing filter 30 a is regenerated, a detection value detected by the odor sensor 51 in a state where the switching plate 56 is rotated toward the indoor side detection hole 54 is set as a reference value of the odor sensor 51. Therefore, even if the detection sensitivity of the deodorization sensor 51 changes due to secular changes or variations in the deodorization sensor 51 itself, automatic operation control can be performed with an appropriate operation air volume.

  In addition, since the deodorizing apparatus 1 sets the reference value of the odor sensor 51, the control means 40 ends the regeneration of the deodorizing performance of the deodorizing filter 30a, and then a predetermined time t3 stored in the storage unit 40a elapses. At this time, the detected value obtained by detecting the air present in the housing by the odor sensor 51 is stored in the storage unit 40 a as the reference value of the odor sensor 51.

Let

  From the point of time when regeneration of the deodorizing filter 30a is started in S1, the control means 40 starts a timer (S2). Next, the control means 40 determines whether or not the predetermined time t2 stored in the storage unit 40a has elapsed (S3). If the predetermined time t2 has elapsed (S3-YES), the process proceeds to S4. If the predetermined time t2 has not elapsed (S3-NO), the process waits until the predetermined time t2 has elapsed.

  In S4, the control means 40 stops the energization to the heater 30b through the heater energization unit 46, and ends the regeneration of the deodorizing filter 30a. The control means 40 will stop operation | movement of the ozone generator 21 and the ion generator 22, if reproduction | regeneration of the deodorizing filter 30a is complete | finished. From the time when the regeneration of the deodorizing filter 30a is finished in S4, the control means 40 starts a timer (S5). Next, the control means 40 determines whether or not a predetermined time t3 stored in the storage unit 40a has elapsed (S6). If the predetermined time t3 has elapsed (S6-YES), the process proceeds to S7. If the predetermined time t3 has not elapsed (S6-NO), the process waits until the predetermined time t3 has elapsed.

  In S <b> 7, the control unit 40 takes in the detection value detected by the odor sensor 51 and stores the acquired detection value in the storage unit 40 a as the reference value of the odor sensor 51. Then, the control means 40 complete | finishes the setting operation of the reference value of the odor sensor 51, and restarts automatic operation control.

  According to the deodorizing apparatus 1 of the present invention described above, the deodorizing filter 30a for deodorizing the air sucked from the suction port 12a into the housing having the air flow path 10 connecting the air suction port 12a and the blowout port 15a. In order to regenerate the deodorizing ability of the deodorizing filter 30a, the heater 30b for heating the deodorizing filter 30a, the control means 40 for controlling the energization of the heater 30b, and the odor component of air existing either inside or outside the housing And an odor sensor unit 50 that houses an odor sensor 51 that is selectively detected. Further, the control means 40 determines whether or not it is necessary to deodorize the air based on the detection value obtained by detecting the air present in the housing by the odor sensor 51 after energizing the heater 30b and regenerating the deodorizing filter 30a. Therefore, a reference value for the odor sensor 51 is set.
