DETAILED DESCRIPTION OF THE INVENTION
[1] A first embodiment of the present invention will be described below with reference to the drawings.
[0031]
1 and 2, reference numeral 1 denotes an indoor unit of an air conditioner, which is installed in a living space. The casing of the indoor unit 1 is provided with suction ports 2a and 2b on the front surface, a suction port 2c on the upper surface, and an air outlet 3 on the lower surface.
[0032]
In the indoor unit 1, a ventilation path 4 is formed from the suction ports 2 a, 2 b, 2 c to the outlet 3, and an indoor fan 5 is provided in the ventilation path. By the operation of the indoor fan 5, room air circulates through the indoor unit 1.
[0033]
In the ventilation path 4, an indoor heat exchanger 6 is disposed between the suction ports 2 a, 2 b, 2 c and the indoor fan 5. A blowout louver 7 for setting a blowing direction is disposed at the blowout port 3.
[0034]
In particular, the suction port 2b on the upper side of the front surface has a protruding shape, and an air cleaner 11 is disposed between the suction port 2b and the indoor heat exchanger 6. The air purifier 11 includes a filter 12 and removes dirt from the intake air such as dust and cigarette smoke together with odors.
[0035]
A dirt sensor 13 is disposed as a dirt detection means between the suction port 2a and the indoor heat exchanger 6. The dirt sensor 13 detects dirt in the intake air, such as dust and cigarette smoke.
[0036]
A control block of the air conditioner is shown in FIG.
[0037]
The compressor 21, the four-way valve 22, the indoor heat exchanger 6, the decompressor, for example, the expansion valve 23, and the outdoor heat exchanger 24 are connected by piping to constitute a heat pump refrigeration cycle.
[0038]
An indoor temperature sensor 31 for detecting the indoor fan 5 and the indoor temperature (intake air temperature) is disposed on the indoor unit side. A heat exchanger temperature sensor 32 is attached to the indoor heat exchanger 6. An outdoor fan 25 is disposed in the vicinity of the outdoor heat exchanger 24.
[0039]
A control circuit 40 controls the entire air conditioner. The control circuit 40 includes an inverter device 41, an indoor fan control circuit 42, an outdoor fan control circuit 43, a remote controller 44, a high voltage generation circuit 45, an indoor temperature sensor 31, and A heat exchanger temperature sensor 32 is connected.
[0040]
The inverter device 41 rectifies the voltage of the commercial AC power supply, converts it into an AC voltage having a predetermined frequency by switching, and outputs the AC voltage. This output becomes the driving power for the compressor 21. The indoor fan control circuit 42 controls the speed of the indoor fan 5. The outdoor fan control circuit 43 controls the speed of the outdoor fan 25. The remote controller 44 is prepared for the user to set the operating conditions of the air conditioner. The high voltage generation circuit 45 outputs a driving voltage for the air cleaner 11.
[0041]
The control circuit 40 includes the following (1) to (4) as main functions.
[0042]
(1) Means for operating the dirt sensor 13 during air-conditioning operation (cooling, heating, dehumidification, etc.).
[0043]
(2) Control means for controlling the operation of the air purifier 11 by comparing the detection result of the dirt sensor 13 with a preset reference value after a predetermined time from the start of operation of the dirt sensor 13 (after the initialization operation).
[0044]
(3) Storage means for storing the minimum value of the detection result of the dirt sensor 13 during the operation of the air purifier 11.
[0045]
(4) After a predetermined time from the start of operation of the dirt sensor 13 (after the initialization operation), when the detection result of the dirt sensor 13 is larger than the set value by more than the stored minimum value during the previous operation of the air cleaner 11, Reference value adjusting means for setting the minimum value as the reference value.
[0046]
A schematic perspective view of the indoor unit 1 is shown in FIG.
[0047]
Next, the operation of the above configuration will be described.
[0048]
As air conditioning operations such as cooling and heating are started, energization of the dirt sensor 13 is started, and the dirt sensor 13 starts operating.
[0049]
When dirt is generated in the living space, for example, when the user starts to smoke and smoke is generated, the smoke sensor 13 detects the smoke. The dirt sensor 13 outputs a voltage level signal corresponding to the degree of dirt (smoke).
[0050]
The detection result (voltage level) of the dirt sensor 13 is compared with a preset reference value, and when the detection result is larger than the reference value, the operation of the air cleaner 11 (and the operation of the indoor fan 5) is started. . By this operation, dirt is removed.
[0051]
When the dirt is removed and the detection result of the dirt sensor 13 falls below the reference value, the operation of the air cleaner 11 (and the operation of the indoor fan 5) stops.
[0052]
The operation of the air purifier 11 is not limited to when the air conditioning operation is performed. Even when the air conditioning operation is not performed, the operation of the air cleaner 11 (and the operation of the indoor fan 5) is independently performed according to the detection result of the dirt sensor 13.
[0053]
In this way, it is possible to automatically catch and remove indoor air dirt regardless of whether or not the air conditioning operation is performed. Not only dirt such as dust and cigarette smoke, but also odor can be removed. Therefore, the living space can always be kept comfortable.
[0054]
However, in the case where the air cleaning operation mode is started in a state where the indoor space is dirty, if the detection result of the dirt sensor 13 after the completion of the initialization operation is set as a reference value for operation control of the air cleaner 11 as it is, Since the dirty state becomes the reference, there arises a problem that the operation of the air purifier 11 is not started even though it is dirty.
[0055]
Therefore, as shown in the flowchart of FIG. 5, during the operation of the air cleaner 11, the minimum value of the detection result of the dirt sensor 13 is stored in the memory (storage means) in the control circuit 40 (steps S7 to S11). Then, when the initialization operation in the first predetermined time from the start of operation of the dirt sensor 13 is completed, the detection result of the dirt sensor 13 at that time is a set value from the lowest value stored in the memory during the previous operation of the air purifier 11. When it is larger than that (under the judgment that the indoor space is dirty), the minimum value is set as the reference value for the operation control of the air cleaner 11 (steps S4 and S5).
[0056]
The lowest value during the previous operation corresponds to the detection result when the indoor space is most clean.
[0057]
By setting the reference value as described above, even when the air cleaning operation mode is started in a state where the indoor space is dirty, after the initialization operation is completed, the dirty state of the indoor space can be properly captured, and the air cleaner 11 optimal operation control can be performed.
[0058]
[2] A second embodiment will be described.
[0059]

S11). Then, when the initialization operation in the first predetermined time from the start of operation of the dirt sensor 13 is completed, the detection result of the dirt sensor 13 at that time is a set value from the lowest value stored in the memory during the previous operation of the air purifier 11. When the value is larger (under the judgment that the indoor space is dirty), a value lower than the detection result by a predetermined value is set as a reference value for operation control of the air purifier 11 (steps S4 and S5).
[0060]
The lowest value during the previous operation corresponds to the detection result when the indoor space is most clean.
[0061]
If the difference between the detection result of the dirt sensor 13 when the initialization operation is completed and the minimum value at the previous operation of the air purifier 11 is large, setting the minimum value as a reference value as it is is actually As a result, an excessive air purifying function exceeding the amount of dirt is exhibited, and energy is wasted. Considering this point, a value lower than the detection result by a predetermined value is set as the reference value.
[0062]
By setting the reference value as described above, even when the air cleaning operation mode is started in a state where the indoor space is dirty, after the initialization operation is completed, the dirty state of the indoor space can be properly captured, and the air cleaner 11 optimal operation control can be performed.

When the value is larger (under the judgment that the indoor space is dirty), a value lower than the detection result by a predetermined value corresponding to the detection result is set as the reference value for the operation control of the air cleaner 11.
[0066]
The lowest value during the previous operation corresponds to the detection result when the indoor space is most clean.
[0067]
If the difference between the detection result of the dirt sensor 13 when the initialization operation is completed and the minimum value at the previous operation of the air purifier 11 is large, setting the minimum value as a reference value as it is is actually As a result, an excessive air purifying function exceeding the amount of dirt is exhibited, and energy is wasted. Considering this point, a value lower than the detection result is set as the reference value.
[0068]
In particular, a predetermined value set in advance corresponding to the detection result is applied to how much lower the detection result is. This predetermined value corresponds to the excess performance of the air cleaning function.

Other configurations are the same as those of the first embodiment.
[0103]
[9] A ninth embodiment will be described.
[0104]
In this embodiment, as shown in the flowchart of FIG. 9, when the dirt sensor 13 is restarted (start of the air cleaning mode) within a certain time (for example, 1 minute) after the end of the operation (end of the air cleaning mode). After completion of the initialization operation for a predetermined time from the restart of the operation, the reference value used in the control during the previous operation is set as it is as the reference value for the current operation (steps S2 and S16).
[0105]
That is, if the operation of the dirt sensor 13 is resumed within a certain time after the operation is finished, there is no significant difference between the detection result of the dirt sensor 13 at the previous operation and the detection result of the dirt sensor 13 at the current operation.
[0106]
By setting such a reference value, it is possible to appropriately capture the degree of dirt in the indoor space, and optimal operation control of the air cleaner 11 can be performed.
[0107]

[0108]
[10] A tenth embodiment will be described.
[0109]
In the present embodiment, as shown in the flowchart of FIG. 10, when the dirt sensor 13 resumes operation (starts the air cleaning mode) within a certain time (for example, 1 minute) after the operation of the dirt sensor 13 ends (end of the air cleaning mode). After completion of the initialization operation for a predetermined time from the resumption of the operation, the detection result of the dirt sensor 13 is compared with the reference value used in the control at the previous operation, and the reference value at the current operation is determined according to the comparison result. Is set.
[0110]
If the operation of the dirt sensor 13 is resumed within a certain time after the operation is finished, there is no significant difference between the detection result of the dirt sensor 13 at the previous operation and the detection result of the dirt sensor 13 at the current operation.
[0111]
Therefore, the reference value Ve used in the control during the previous operation is actually compared with the detection result (output signal) Vi of the dirt sensor 13 during the current operation. If the condition of [Vi <(Ve + α); α is equivalent to, for example, 3%, the change rate of dirt] is satisfied, the reference value Ve used in the control at the previous operation is directly used as the reference value at the current operation. It is set (steps S2, S16, S17).
[0112]
If the difference between the two is large and the condition of [Vi ≧ (Ve + α)] is satisfied, a value lower than the current detection result Vi by a predetermined value is set as the reference value for the current operation (S16, S6).
[0113]
By setting such a reference value, it is possible to appropriately capture the degree of dirt in the indoor space, and optimal operation control of the air cleaner 11 can be performed.

Other configurations are the same as those of the first embodiment.
[0115]
[11] An eleventh embodiment will be described.
[0116]
In the present embodiment, as shown in the flowchart of FIG. 11, when the dirt sensor 13 is restarted (start of the air cleaning mode) after a certain time (for example, 1 minute) after the end of the operation (end of the air cleaning mode), After completion of the initialization operation at a predetermined time after the restart of the operation, the detection result of the dirt sensor 13 is compared with the lowest value of the detection result of the dirt sensor 13 at the previous operation, and the reference for the current operation is determined according to the comparison result. A value is set (steps S4 to S7).
[0117]
If the time from the end of operation of the dirt sensor 13 to the resumption of operation exceeds a certain time, there is a possibility that a large difference occurs between the detection result of the dirt sensor 13 at the previous operation and the detection result of the dirt sensor 13 at the current operation. There is.
[0118]
Therefore, the minimum value Vmin of the detection result at the previous operation is actually compared with the detection result Vi at the current operation, and if the difference between the two is large, specifically, [Vi ≧ (Vmin + α); If the condition “equivalent to, for example, 3%” is satisfied, for example, a value lower than the detection result Vi by a predetermined value is set as the reference value for the current operation (steps S16 and S6).
[0119]
If the difference between the two is not so large and the condition of [Vi <(Vmin + α)] is satisfied, the reference value Ve used in the control at the previous operation is set as it is as the reference value at the current operation (step S16, S16). S17).
[0120]
By setting such a reference value, it is possible to appropriately capture the degree of dirt in the indoor space, and optimal operation control of the air cleaner 11 can be performed.
[0121]
Other configurations are the same as those of the first embodiment.
[0122]
[12] A twelfth embodiment will be described.
[0123]
If there is a difference between the component detected by the dirt sensor 13 and the component removed by the air purifier 11, even if the air cleaning by the operation of the air purifier 11 advances and the degree of dirt decreases, the dirt sensor 13 There are times when it does not respond easily.
[0124]
In this case, appropriate operation control of the air cleaner 11 becomes difficult.
[0125]
If there is a function of notifying the degree of dirt, the user will feel uncomfortable that the dirt is not removed even though the air purifier 11 continues to be air-cleaned.
[0126]
Therefore, as shown in FIG. 20, after the initialization operation is completed, the reference value for operation control of the air cleaner 11 is changed to V1, V2, V3, and V4 as time elapses, that is, every control time (time interval) t. And variably set in the ascending direction.
[0127]
Thus, by bringing the reference value close to the current detection result Vi, the operation of the air purifier 11 is appropriately controlled in a state in accordance with the progress of the air cleaning, regardless of whether the dirt sensor 13 has reacted or delayed. be able to. In addition, it is possible to perform air cleaning and dirt notification that match the user's feeling.

[0146]
[20] A twentieth embodiment will be described.
[0147]
In the present embodiment, in the same configuration as in the twelfth embodiment, the variable widths of V1, V2, V3, and V4 to be variably set are selected according to the set sensitivity of the dirt sensor 13.
[0148]
Specifically, as shown in FIG. 31, the smaller the setting sensitivity, the smaller the fluctuation range is selected.
[0149]
[21] A twenty-first embodiment will be described.
[0150]
In the present embodiment, an operation function for setting the sensitivity of the dirt sensor 13 is provided in the remote controller 44 in the same configuration as in the thirteenth embodiment. By operating the remote controller 44, the sensitivity of the dirt sensor 13 can be freely adjusted.
[0151]

[0152]
[22] A twenty-second embodiment will be described.
[0153]
In the present embodiment, an operation function for setting the sensitivity of the dirt sensor 13 is provided in the remote controller 44 in the same configuration as in the thirteenth embodiment. By operating the remote controller 44, the sensitivity of the dirt sensor 13 can be freely adjusted. This adjustment is possible both in the air cleaning mode and not.
[0154]
This makes it possible to perform air cleaning and dirt notification without a sense of incongruity that matches the user's actual feeling.
[0155]
[23] A twenty-third embodiment will be described.
[0156]
In this embodiment, the remote controller 44 is provided with an operation function for setting the sensitivity of the dirt sensor 13 in the same configuration as that of the twelfth embodiment. By operating the remote controller 44, the sensitivity of the dirt sensor 13 can be freely adjusted.
[0157]
In particular, the remote controller 44 has not only a sensitivity operation function but also an operation function related to setting of an operation mode, a room temperature, and the like. Therefore, the user can reliably perform the sensitivity setting of the dirt sensor 13 when performing the setting operation such as the operation mode and the room temperature.
[0158]
This makes it possible to perform air cleaning and dirt notification without a sense of incongruity that matches the user's actual feeling.
[0159]
[24] A twenty-fourth embodiment will be described.
[0160]
In the present embodiment, when there is a difference between the component detected by the dirt sensor 13 and the component removed by the air purifier 11, even if the air cleaning by the operation of the air purifier 11 proceeds and the degree of dirt decreases, The dirt sensor 13 may not respond easily.
[0161]
In this case, appropriate operation control of the air cleaner 11 becomes difficult.
[0162]
If there is a function of notifying the degree of dirt, the user will feel uncomfortable that the dirt is not removed even though the air purifier 11 continues to be air-cleaned.
[0163]
Therefore, after completion of the initialization operation, the reference value for operation control of the air cleaner 11 is variably set according to the change in the detected temperature Ta of the indoor temperature sensor 31.
[0164]
That is, in the combined operation of the air conditioning operation and the air cleaning operation, there is a feature that the indoor temperature Ta changes while the air cleaning progresses. Focusing on this point, the reference value is variably set according to the change of the indoor temperature Ta. I am doing so.
[0165]
Thereby, it is possible to appropriately control the operation of the air purifier 11 in a state in accordance with the progress of the air cleaning regardless of the presence / absence or delay of the reaction of the dirt sensor 13. In addition, it is possible to perform air cleaning and dirt notification that match the user's feeling.
[0166]
Other configurations are the same as those of the first embodiment.
[0167]
[25] A twenty-fifth embodiment will be described.
[0168]
In the same configuration as in the twenty-fourth embodiment, when the reference value is variably set according to the change in the detected temperature Ta of the indoor temperature sensor 31, the fluctuation range of the variably set corresponds to the detected temperature change amount ΔTa from the start of operation. Selected.
[0169]
Specifically, as shown in FIG. 32, a larger fluctuation range is selected as the indoor temperature change amount ΔTa from the start of operation increases.
[0170]
[26] A twenty-sixth embodiment will be described.
[0171]
In the same configuration as in the twenty-fourth embodiment, when the reference value is variably set according to the change in the detected temperature Ta of the indoor temperature sensor 31, the variable setting fluctuation range is a predetermined time (for example, the control time t shown in FIG. 20). Each temperature is selected according to the detected temperature change amount ΔTa.
[0172]
Specifically, as shown in FIG. 33, a larger fluctuation range is selected as the indoor temperature change amount ΔTa per predetermined time is larger.
[0173]
[27] A twenty-seventh embodiment will be described.
[0174]
In the same configuration as in the twenty-fourth embodiment, the reference value is variably set in the increasing direction as the detected temperature Ta of the indoor temperature sensor 31 increases.
[0175]
[28] A twenty-eighth embodiment will be described.
[0176]
In the same configuration as in the twenty-fourth embodiment, when the reference value is variably set according to the change in the detected temperature Ta of the indoor temperature sensor 31, the variable range of the variable setting varies depending on the change direction of the detected temperature Ta. Selected.
[0177]
Specifically, as shown in FIG. 34, the fluctuation range is large when the detected temperature Ta rises, the fluctuation range is small when it falls, and the so-called standard time that is neither rising nor falling is an intermediate fluctuation range between rising and falling. Is selected.
[0178]
[29] A twenty-ninth embodiment will be described.
[0179]
When a gas sensor is used as the dirt sensor 13, the dirt sensor 13 may be affected by the temperature Tc of the nearby indoor heat exchanger 6 in addition to the dirt, and the output signal may change.
[0180]
If there is a function of notifying the amount of dirt, the user may have a distrust that the dirt is not removed even though the air cleaning operation is proceeding.
[0181]
Therefore, after completion of the initialization operation, the reference value for operation control of the air purifier 11 is variably set according to the change in the detected temperature of the heat exchanger temperature sensor 32 (temperature of the indoor heat exchanger 6) Tc.
[0182]
Specifically, as shown in FIG. 35, when the detected temperature Tc increases, the fluctuation range is large, when the detection temperature Tc is low, the fluctuation range is small. Is selected.
[0183]
By such a variable setting of the reference value, dirt is reliably removed in terms of control, and distrust related to dirt notification is eliminated.
[0184]
Other configurations are the same as those of the first embodiment.
[0185]
[30] A thirtieth embodiment will be described.
[0186]
In the same configuration as that of the twenty-ninth embodiment, during heating operation in which the indoor heat exchanger 6 functions as a condenser and the outdoor heat exchanger 24 functions as an evaporator, frost gradually adheres to the outdoor heat exchanger 24. Heat exchange efficiency is reduced, which adversely affects heating. Therefore, the so-called reverse cycle defrosting in which the high-temperature refrigerant flows into the outdoor heat exchanger 24 by switching the four-way valve 22 is performed periodically or as necessary, and the frost attached to the outdoor heat exchanger 22 is removed. During the defrosting, the temperature Tc of the indoor heat exchanger 6 on the low pressure side rapidly decreases.
[0187]
When the temperature Tc of the indoor heat exchanger 6 is rapidly decreased, the output signal of the dirt sensor 13 is lowered due to the influence of the radiation temperature, and the dirt is removed in terms of control. Then, when the defrosting is completed, the temperature Tc of the indoor heat exchanger 6 rapidly increases, and the output signal of the dirt sensor 13 rises due to the influence of the radiation temperature, and dirt is generated in terms of control. .
[0188]
Therefore, the reference value is maintained in the state before the defrosting without variably setting the reference value for the first predetermined time after the start of defrosting.
[0189]
Thereby, the bad influence by the change of the indoor heat exchanger temperature Tc is eliminated as much as possible, and the operation of the air cleaner 11 and the contamination notification can be performed in accordance with the progress of the air cleaning.
[0190]
[31] A thirty-first embodiment will be described.
[0191]
In the 29th embodiment, during heating operation in which the indoor heat exchanger 6 functions as a condenser and the outdoor heat exchanger 24 functions as an evaporator, frost gradually adheres to the outdoor heat exchanger 24, and heat exchange efficiency is improved as it is. Decreases and adversely affects heating. Therefore, the so-called reverse cycle defrosting in which the high-temperature refrigerant flows into the outdoor heat exchanger 24 by switching the four-way valve 22 is performed periodically or as necessary, and the frost attached to the outdoor heat exchanger 22 is removed. During the defrosting, the temperature Tc of the indoor heat exchanger 6 on the low pressure side rapidly decreases.
[0192]
When the temperature Tc of the indoor heat exchanger 6 is suddenly lowered, the output signal of the dirt sensor 13 is lowered due to the influence of the radiation temperature, and the dirt is removed in terms of control. When the defrosting is completed, the temperature Tc of the indoor heat exchanger 6 is rapidly increased, and the output signal of the dirt sensor 13 is increased due to the influence of the radiation temperature, and the dirt is generated in terms of control. .
[0193]
Therefore, during the defrosting and for a predetermined time after the completion of the defrosting, the reference value is maintained in the state before the defrosting without variably setting the reference value.
[0194]
Thereby, the bad influence by the change of the indoor heat exchanger temperature Tc is eliminated as much as possible, and the operation of the air cleaner 11 and the contamination notification can be performed in accordance with the progress of the air cleaning.
[0195]
[32] A thirty-second embodiment will be described.
[0196]
In the 29th embodiment, during heating operation in which the indoor heat exchanger 6 functions as a condenser and the outdoor heat exchanger 24 functions as an evaporator, frost gradually adheres to the outdoor heat exchanger 24, and heat exchange efficiency is improved as it is. Decreases and adversely affects heating. Therefore, the so-called reverse cycle defrosting in which the high-temperature refrigerant flows into the outdoor heat exchanger 24 by switching the four-way valve 22 is performed periodically or as necessary, and the frost attached to the outdoor heat exchanger 22 is removed. During the defrosting, the temperature Tc of the indoor heat exchanger 6 on the low pressure side rapidly decreases.
[0197]
When the temperature Tc of the indoor heat exchanger 6 is rapidly decreased, the output signal of the dirt sensor 13 is lowered due to the influence of the radiation temperature, and the dirt is removed in terms of control. Then, when the defrosting is completed, the temperature Tc of the indoor heat exchanger 6 rapidly increases, and the output signal of the dirt sensor 13 rises due to the influence of the radiation temperature, and dirt is generated in terms of control. .
[0198]
If there is a function of notifying the amount of dirt and the capacity state of the air cleaner 11, the user may have a distrust that the dirt is not removed even though the air cleaning operation is in progress.
[0199]
Therefore, the reference value is maintained in the state before the defrosting for a predetermined time after defrosting, without variably setting the reference value.
[0200]
Thereby, the bad influence by the change of the indoor heat exchanger temperature Tc is eliminated as much as possible, and the operation of the air cleaner 11 and the contamination notification can be performed in accordance with the progress of the air cleaning.
[0201]

[0237]
In the present embodiment, the gas sensor 60 shown in FIG.
[0238]
The gas sensor 60 includes a heating element 61 and a gas sensing element 62, and is operated by the heat generation of the heating element 61 by application of the voltage Vh. The gas sensing element 62 reacts to the gas. At this time, the resistance value of the gas sensitive body 62 changes according to the gas concentration. A voltage Vc is applied to the gas sensitive body 62 via the load resistor R1, and a voltage Vi having a level corresponding to a change in the resistance value of the gas sensitive body 62 is generated in the load resistor R1. This voltage Vi is output as a detection result.

[0247]
That is, as shown in FIG. 23, assuming that there are five light emitting diodes, five light emitting diodes are turned on when the degree of dirt detected by the dirt sensor 13 is large, and three light emitting diodes if the degree of dirt is small. Lights up and one light-emitting diode lights up when it is clean and clean.
[0248]
Note that a plurality of light emitting diodes having different colors may be prepared, and color-coded display according to the degree of contamination may be performed.
[0249]

[0251]
[47] A 47th embodiment will be described.
[0252]

[0254]
[48] A forty-eighth embodiment will be described.
[0255]
In this embodiment, when the air cleaning operation (including the combined operation of the air conditioning operation and the air cleaning operation) is set by the remote controller 44, the energization to the dirt sensor 13 is started and the dirt sensor 13 starts to operate. To do.
[0256]
That is, as shown in the flowchart of FIG. 24, after the air cleaning operation is set and the substantial air cleaning mode is started (YES in step 101), energization to the dirt sensor 13 is started (step 102). ). As a result, the dirt sensor 13 starts operating. After the initialization operation of the dirt sensor 13 (step 103), the dirt monitoring by the dirt sensor 13 is executed (step 104). When dirt is detected (YES in step 105), the operation of the air cleaner 11 is started (step 106).
[0257]
In short, the dirt sensor 13 is operated only in the substantial air cleaning mode, and in the air conditioning operation, the power supply to the dirt sensor 13 is stopped to obtain a power saving effect.
[0258]
Other configurations are the same as those of the first embodiment.
[0259]
[49] A forty-ninth embodiment will be described.
[0260]
In this embodiment, at the start of the operation of the dirt sensor 13, as shown in FIG. 25, until the predetermined time (about 2 minutes) elapses, the resistance value of the gas sensitive body 62 greatly decreases, A signal of a different level may be output.
[0261]
Therefore, a predetermined time (about 2 minutes) after the start of operation is assigned to the initialization operation, and during that time, the output signal of the dirt sensor 13 is ignored to avoid erroneous detection of dirt.
[0262]
That is, as shown in the flowchart of FIG. 26, after the air cleaning operation is set and the substantial air cleaning mode is started (YES in step 101), energization to the dirt sensor 13 is started (step 102). ). As a result, the dirt sensor 13 starts operating. Then, after the initialization operation of the dirt sensor 13 is executed for a predetermined time (YES in Step 103 and Step 107), the dirt monitoring by the dirt sensor 13 is executed (Step 104). When dirt is detected (YES in step 105), the operation of the air cleaner 11 is started (step 106).
[0263]
In short, highly accurate dirt detection is performed without being affected by the characteristics of the dirt sensor 13.
[0264]
Other configurations are the same as those of the first embodiment.
[0265]
[50] A 50th embodiment will be described.
[0266]
In this embodiment, at the start of the operation of the dirt sensor 13, as described above, the resistance value of the gas sensitive body 62 greatly decreases until a predetermined time (about 2 minutes) elapses. May be output.
[0267]
Therefore, until the level of the output signal of the dirt sensor 13 reaches a predetermined value, the output signal of the dirt sensor 13 is ignored to avoid erroneous detection of dirt. Thereby, highly accurate dirt detection is performed without being affected by the characteristics of the dirt sensor 13.
[0268]
Other configurations are the same as those of the first embodiment.
[0269]
[51] A 51st embodiment will be described.
[0270]
In the present embodiment, several light emitting diodes are used as display means for displaying the detection result of the dirt sensor 13 or the capability state of the air purifier 11 at a position visible to the user on the outer peripheral surface of the casing of the indoor unit 1. (LED) is provided.
[0271]
At the start of a substantial air cleaning mode based on the setting of air cleaning operation (including combined operation of air conditioning operation and air cleaning operation), each of the light emitting diodes is turned on at least one, and the initialization operation ends. After that, the number of light emitting diodes corresponding to the degree of dirt detection of the dirt sensor 13 is turned on.
[0272]
The dirt sensor 13 may output a signal having a level different from the actual dirt until a predetermined time (about 2 minutes) elapses when the operation starts. For this reason, it is difficult to correctly report the degree of contamination according to the number of light-emitting diodes that are turned on from the beginning.
[0273]
Therefore, as described above, during the initialization operation after the start of the operation of the dirt sensor 13, the minimum number of light-emitting diodes are turned on to notify that the air cleaning mode has started, but that the initialization operation is in progress. I have to.
[0274]
By performing such display, not only the notification of the degree of dirt in the living space, but also the progress of dirt detection can be easily informed to the user, and serviceability is improved.
[0275]
Other configurations are the same as those of the first embodiment.
[0276]
[52] A 52nd embodiment will be described.
[0277]
In this embodiment, during the initialization operation after the start of the operation of the dirt sensor 13, the intermediate number, for example, three light-emitting diodes are turned on to notify that the air cleaning mode has started, but that the initialization operation is in progress. Is done.
[0278]
The rest is the same as the 51st embodiment.
[0279]
[53] A 53rd embodiment will be described.
[0280]
In the present embodiment, during the initialization operation after the start of the operation of the dirt sensor 13, one light emitting diode, which is the minimum number, blinks and the air cleaning mode is started, but the initialization operation is in progress. Informed.
[0281]
The rest is the same as the 51st embodiment.
[0282]
[54] The 54th embodiment will be described.
[0283]
In this embodiment, at the start of the operation of the dirt sensor 13, as described above, the resistance value of the gas sensitive body 62 greatly decreases until a predetermined time (about 2 minutes) elapses. May be output.
[0284]
That is, even if the operation of the dirt sensor 13 is started, it is impossible to know how much the room air is dirty for the first predetermined time.
[0285]
Therefore, the operation of the indoor fan 5 is started simultaneously with the start of the operation of the dirt sensor 13, but when there is a control function for adjusting the air volume of the indoor fan 5 according to the degree of dirt in the room air, the first predetermined In the initialization operation in time, the air volume of the indoor fan 5 is forcibly set to a minimum air volume, for example, an ultra-fine wind.
[0286]
In short, by prohibiting air volume adjustment when the degree of soiling is not known, the residents are not discomforted.
[0287]
Other configurations are the same as those of the first embodiment.
[0288]
[55] A 55th embodiment will be described.
[0289]
In the present embodiment, when there is a control function for adjusting the air volume of the indoor fan 5 in accordance with the degree of contamination of the indoor air, the initialization of the indoor fan 5 in the initial predetermined operation after the start of the operation of the contamination sensor 13 is performed. The air volume is forcibly set to an intermediate air volume, for example, a light wind.
[0290]
