Description

  The present invention relates to control of an air conditioner equipped with an ion generator.

  Conventionally, as a method for controlling ion release, for example, according to the invention described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-170002), ion release into a bathroom is caused by the state of the bath, that is, in the bath. The water level and temperature are detected by a water level sensor, water temperature sensor, etc., and ion emission is automatically controlled.

  For example, if the water temperature in the bath is at a set temperature, it is assumed that a person is taking a bath and ions are released.

  Apart from this, it is also known that by releasing ions into the air, it is possible to inactivate suspended particles in living spaces, kill suspended bacteria and denature odor components to deodorize them. ing. This is to operate the ion generator in a living space, for example, a partitioned room, and discharge ions as necessary. In this case, normally, the user can freely select a mode for releasing ions and a mode for not releasing ions. An “ON / OFF” switch is provided as a mode selection switch (operation unit) so that the ion mode can be selected.

JP 2004-170002 A

  Ions are generated in air conditioners equipped with an ion generator that inactivates suspended particles in living spaces, kills suspended bacteria, denatures odor components, and deodorizes them by releasing ions into the air. In addition to the “ON / OFF” button (switch) for selecting the mode, an operation switching button (switch) for switching various operation modes for air conditioning is provided. Can be selected.

  Therefore, when switching to a specific operation mode that has an effect such as deodorization or air purification, a contradiction arises if the ion mode is “off”. When a specific operation mode for deodorization or air purification is selected, it is necessary to release ions, and the ion mode selection switch must be “ON”.

  Further, in the method of automatically switching the ion generation mode using the sensor or the like described in Patent Document 1, the ion mode is not automatically “ON” even if a specific operation mode is selected. In other words, it is a method to control the ion mode, that is, whether or not to release ions, depending on the sensor value. Even if a specific operation mode is selected, the ion mode may be “off”, which is a problem as a control. There is.

  An object of the present invention is to solve the above problems.

  The present invention also includes an ion mode selection button (switch) and an operation switching button (switch) for switching the operation mode, each of which can independently select a mode, a humidifier, a humidity / An object of the present invention is to provide a control method that enables ion emission by selecting a specific operation mode in an air conditioner such as an air conditioner that performs temperature adjustment.

  In order to solve the above problems, when switching to a specific operation mode, even if the ion mode “OFF” was selected in the previous operation mode, it is specified by forcibly switching to the ion mode “ON”. In this operation mode, ion emission can be controlled.

  As a result, an air purification / deodorization effect can be expected in a specific operation mode.

  In the above-described specific operation mode, the ion mode is forcibly set to “ON”, after which the operation mode is switched to return to the ion mode “OFF” when a mode other than the specific operation mode is selected. In other words, the selection mode before the ion mode “on” is forcibly returned. This is because the user has intentionally selected the ion mode “OFF” before selecting a specific operation mode, so when the ion effect is not particularly active, the original ion mode selected by the user is restored. return.

  However, even if the specific operation mode is selected and the ion mode is forcibly set to “ON”, there may be some users who want to set the ion mode to “OFF”. "/ Off" operation is possible.

  In addition, when the ion mode “ON / OFF” operation was performed in the specific operation mode, the user intentionally performed the ion mode “ON / OFF” operation, so the operation mode was switched to a mode other than the specific operation mode. In the case, the ion mode last selected in the specific operation mode is reflected.

  According to the ion control method according to the above-described configuration of the present invention, when switching to a specific operation mode, the ion is forcibly switched to “ON”, and ions are released in the specific operation mode. As a result, an air purification / deodorization effect can be expected from the released ions.

Moreover, even if the ion mode is forcibly set to “ON” in the specific operation mode, the ion mode selection operation on the user side can be reflected, and the operability for the user can be improved.

  As described above, according to the present invention, the effect of ions can be expected without contradiction to the name of the operation mode, and control with good operability can be achieved.

(First embodiment)
In the following, an embodiment of the present invention will be described with reference to the drawings, taking a cold air machine as an example, for controlling ion emission of the present invention. 1 and 2 show the internal structure of the cold air machine 101 of the present invention. FIG. 1 shows a state during cold air operation or clothing deodorization operation in which the movable plate closes the path from the second ventilation path to the first ventilation path, and FIG. 2 shows the movable plate from the second ventilation path to the first. The state at the time of the drying operation (dehumidification operation) which opened the path | route to the ventilation path is shown. The cold air machine 101 can perform a dry operation in addition to the cold air operation. The outer shell is composed of a main body 102 in which a generally flat box is vertically set up. Inside the main body 102, a first air passage 110 is provided on the upper side, and a second air passage 120 is provided on the lower side. Each is formed.

  The main body 102 has a first suction port 111 serving as an air inlet to the first air passage 110 on the rear surface (left side in the drawing) of the front, rear, left and right side surfaces. On the front surface (right side in the figure) that is just opposite to the rear surface on which the first suction port 111 is formed, a first outlet 112 serving as an outlet for air from the first air passage 110 is provided on the main body. An opening is formed from the upper surface to the upper surface of the front surface of 102. The first air outlet 112 is provided with a pair of louvers 113A and 113B at the top and bottom. The upper louver 113A and the lower louver 113B are respectively supported by supporting shafts (not shown) extending in the left-right direction independently of each other, and rotate in conjunction with each other about the supporting shafts. ing. In the path of the first ventilation path 110, an evaporator 114 and a first blower 115 are arranged in this order behind the first suction port 111. The evaporator 114 is a heat exchanger that forms a refrigeration cycle in a pair with a condenser 124 to be described later and circulates refrigerant between each other, and removes heat from the surroundings by evaporating the liquid refrigerant. is there. The first blower 115 includes a fan motor and a fan.

  Further, on the rear surface of the main body 102, a second suction port 121 serving as an air inlet to the second air passage 120 is opened below the first suction port 111. Immediately above the second suction port 121, a second air outlet 122 serving as an air outlet from the second air passage 120 opens. In the second air passage 120, a condenser 124 and a second blower 125 are arranged in this order behind the second suction port 121. The condenser 124 is a heat exchanger that applies heat to the surroundings in order to cool and condense the gaseous refrigerant. The second blower 125 includes a fan motor and a fan. In the circulation path (not shown) from the evaporator 114 to the condenser 124, a compressor 129 that compresses the gaseous refrigerant from the evaporator 114 and sends it to the condenser 124 is arranged.

  In particular, the second air passage 120 extends upward from the second blower 125 and then bends horizontally to reach the second outlet 122. The vent 114 is connected between the evaporator 114 and the first blower 115. A damper 123 that opens and closes the path from the second ventilation path 120 to the first ventilation path 110 is provided at the branch portion. The damper 123 here is supported by a support shaft 123a along the left-right direction, and is rotated about the support shaft 123a. With respect to the path of the second ventilation path 120, the damper 123 rotates to open the path to the second air outlet 122 and close the path to the first air path 110, and the second air outlet 122. It is possible to take a posture of opening the route to the first air passage 110 while closing the route to the.

  In the cold air operation, as shown in FIG. 1A, the damper 123 is in a posture to close the path to the first ventilation path 110. When the first blower 115 is driven in this state, indoor air, which is external air on the rear surface side, is sucked from the first suction port 111 and introduced into the first ventilation path 110 accordingly. (See solid arrow in the figure). The introduced air passes through the evaporator 114, is discharged from the first blower 115, is guided upward, and is blown out from the first blowout port 112 to a room that is outside the front side. At that time, the air is cooled by taking heat in the process of passing through the evaporator 114, and moisture in the air appears on the surface of the evaporator 114 as dew condensation. The condensed water is discharged out of the first air passage 110 through the drain port 116, and is received and stored in the drain tank 117 through a connecting pipe (not shown). In this way, cold air, which is dry and cold air, is blown out from the first outlet 112.

  On the other hand, when the second blower 125 is driven, indoor air, which is external air on the rear surface side, is sucked from the second suction port 121 and introduced into the second air passage 120 accordingly ( (See dashed arrows in the figure). The introduced air passes through the condenser 124 and is then discharged from the second blower 125 and guided upward. Further, the introduced air is guided by the damper 123 and guided rearward. It is blown out to the room which is outside. At that time, the air is heated by being given heat in the process of passing through the condenser 124. In this way, warm air that is warm air is blown out from the second outlet 122.

  On the contrary, in the drying operation, as shown in FIG. 2, the damper 123 is in a posture to open the path to the first ventilation path 110. In this state, as the first blower 115 is driven, indoor air, which is external air on the rear side, is sucked from the first suction port 111 and introduced into the first air passage 110, and the air is evaporated. It is cooled in the process of passing through the vessel 114 (see solid line arrow in the figure). On the other hand, as the second blower 125 is driven, indoor air, which is external air on the rear side, is sucked from the second suction port 121 and introduced into the second air passage 120, and the air is condensed. Heat is applied in the process of passing through the vessel 124 (see broken line arrows in the figure). The heated air is introduced from the second air passage 120 into the first air passage 110 and mixed with the dry and cold air from the evaporator 114, and is left outside the front side from the first outlet 112 as it is. It is blown out into a room. Thus, dry air having an appropriate temperature of about room temperature is blown out from the first outlet 112.

  Further, the ion generator 8 is installed in the vicinity of the outlet of the first outlet 112 so that only the ion generating surface is exposed to the air passage. When the ion “ON” and “OFF” buttons are operated and ion operation is selected, or when ion operation is performed by forced operation, ions are delivered (released) from the outlet 112 into the room.

In the present invention, the ion lamp is turned on when the ion generator 8 starts operating when the ion on / off button 3 shown in FIG. The ion generator 8 generates positive ions and negative ions. The most stably generated positive ion is H ⁺ (H ₂ O) _n , and the most stably generated negative ion is O ₂ ⁻ (H ₂ O) _m . Positive ions and negative ions alone have a weak sterilization effect against airborne bacteria, but when they are generated at the same time, hydrogen peroxide H ₂ O ₂ or hydroxyl radical (.OH), which is an active species, is generated by a chemical reaction. Bacteria produced and suspended in the air with strong activity of H ₂ O ₂ or (.OH) can be removed. If the ion on / off button 3 is pressed again, the operation of the ion generator 8 stops and the ion lamp is turned off.

  An operation unit according to the present invention is shown in FIG. Operation “ON / OFF” can be performed by operating the operation ON / OFF button 1. When the operation is on, the off timer button 2 is used to set the off timer, the ion button 3 is used to turn the ion “on / off”, the air volume switching button 4 is used to set the air volume, the swing louver button 5 is used to adjust the wind direction, and the operation switching button 6 is used. The operation mode can be switched. When the operation is “OFF”, operations other than the operation ON / OFF button 1 are invalid.

  FIG. 6 shows a control block diagram of the cool air fan. When the operation switching button 6 is pressed, the operation mode is switched by the control device 9 comprising a microcomputer, and the louver motor 7, the fans 115 and 125, the compressor 129, and the ion generator are moved so as to follow the specifications of the respective operation modes. 8 is controlled.

  When the ion button 3 is pressed, the ion generator 8 is controlled by the control device 9 formed of a microcomputer.

  FIG. 4 shows a flowchart of the control of the present invention. This flow chart shows a state of operation “ON” by operating the operation ON / OFF button 1 in FIG. 3.

  In S1, it is determined whether the ion button 3 is pressed. If it is determined that it has been pressed, “ON / OFF” of the current ion mode IONMD is determined (S2). If it is determined in S1 that the ion button has not been pressed, the process proceeds to S3. If the current ion mode IONMD is “ON” in S2, the current ion mode IONMD is changed to “OFF” (S2-1). Otherwise, the current ion mode IONMD is changed to “ON” (S2). -2). Next, the current ion mode IONMD is transferred to the previous ion mode IONMDB (S2-3).

  Next, it is determined whether the operation switching button 6 has been pressed (S3). If it is determined that the button has not been pressed, the process returns to S1 and the operation is continued. If it is determined in S3 that the operation switching button 6 has been pressed, it is determined whether the current operation mode UTNMD is cold air (S4). When the operation mode UTNMD is cold air, the operation mode UTNMD changes to clothes drying (S4-1), the previous ion mode IONMDB is transferred to the current ion mode IONMD (S4-2), and the process returns to S1.

  When it is determined in S4 that the current operation mode UTNMD is not cold air, the process proceeds to S5 to determine whether the operation mode UTNMD is clothes drying. When the current operation mode UTNMD is clothes drying, the operation mode UTNMD changes to automatic dehumidification (S5-1), the previous ion mode IONMDB is transferred to the current ion mode IONMD (S5-2), and the process returns to S1.

  When it is determined in S5 that the current operation mode UTNMD is not clothing drying, the process proceeds to S6, and it is determined whether the operation mode UTNMD is automatic dehumidification. When the current operation mode UTNMD is automatic dehumidification, the operation mode UTNMD changes to mold dehumidification (S6-1), the current ion mode IONMD is forcibly switched to "ON" (S6-2), and returns to S1. .

  When it determines with the present operation mode UTNMD not being automatic dehumidification in S6, it moves to S7 and determines whether the operation mode UTNMD is mold dehumidification. When the operation mode UTNMD is mold dehumidification, the operation mode UTNMD changes to clothing deodorization (S7-1), the current ion mode IONMD is forcibly switched to "ON" (S7-2), and the process returns to S1.

  If it is determined in S7 that the current operation mode UTNMD is not mold dehumidification, the process proceeds to S8-1, the operation mode UTNMD changes to cold air, and the previous ion mode IONMDB is transferred to the current ion mode IONMD (S8-2). Return to S1.

  The operation mode of the cool air fan of the present invention is the “cold air” mode (the air flow is shown in FIG. 1 (a)) in which the refrigeration cycle is driven and the cool air and the hot air are sent from separate outlets, and the refrigeration cycle is driven. Then, “clothing drying” mode (air flow is shown in FIG. 2) in which cold air and hot air are mixed and sent out from the same outlet, the refrigeration cycle is driven, and operation control is performed based on the detection result of the humidity sensor. “Automatic dehumidification” mode (air flow is shown in FIG. 2), “mold dehumidification” mode in which the refrigeration cycle is driven and the ion generator 8 is operated to perform dehumidification operation while delivering ions (the air flow is shown in FIG. 2). And a “clothing deodorization” mode in which the refrigeration cycle is stopped, only the ion generator 8 and the first blower 115 or the second blower 125 are operated, and air is blown together with the generated ions from the first outlet. . For example, as shown in FIG. 1B, the air flow in the “clothing deodorization” mode is such that the first blower 115 is operated and the generated ions are blown out through the first air passage 110. 112.

  In the present invention, the specific operation modes in which the effect of ions is given are mold dehumidification and clothing deodorization. When these two modes are selected, the ion mode IONMD is forcibly switched to “ON” as described above. (S6-2, S7-2). Further, when switching to a mode other than the specific operation mode, the cool air (S8-1) is used here. However, if the ion mode is not switched in the specific operation mode, the ion mode before selecting the specific operation mode ( If the ion mode is switched in a specific operation mode (S2-2), the ion mode is reflected (S8-2).

  The cool air blower of the present invention is provided with an air volume switching button 4 and a swing louver on / off button 5, which respectively operate air volume “strong” and “weak” switching and louver swing operation “on” and “off”. Since the control is similar to the conventional control, detailed description thereof is omitted.

  As described above, according to the present invention, when a specific operation mode that emphasizes the effect of ions is selected, the ion mode is forcibly set to “ON”, thereby ensuring the effect of ions in the specific operation mode. Can be provided to the user, and a control method with good operability is provided.

  According to the control described in the first embodiment of the present invention, the specific operation modes are the “mold dehumidification” mode and the “clothing deodorization” mode. In addition to these modes, an operation mode in which the ion generator must be operated to send (discharge) ions to the outside. If that mode is selectable, the ion mode is set to “On” in the same manner. That's fine.

  Here, as described a little earlier, when a specific operation mode is selected and the operation is performed in the specific operation mode, the ion mode is forcibly set to “ON”. When the operation is performed in the specific operation mode, if the operation mode is switched to another operation mode, the ion mode is returned to the ion mode before the specific operation mode is selected. Thereby, control in the ion mode set by the original user is executed. Therefore, every time the user performs an operation for switching the operation mode, the ion mode switching operation is not required, and the operation in the ion mode previously desired by the user is performed. Therefore, each time the operation of the ion button 3 can be reduced, the operability can be improved, that is, the operation can be simplified.

  In addition, when switching to a specific operation mode, the ion mode is forcibly set to “ON”, but even in the operation mode state, the user can operate the ion button 3 to switch the ion mode. Yes. For example, if the ion mode 3 is forcibly set to “ON” and the ion button 3 is operated in this state, the ion mode “OFF” is set. Further, if the ion button 3 is operated (pressed) in this state, the operation can be switched to the ion mode “ON”. Thereby, the operation in the ion mode desired by the user can be enabled.

  Further, as described above, during the operation control in the specific operation mode, the ion mode can be switched by the ion button 3. At this time, when the operation switching button 6 is operated and, for example, the “cold air” mode is selected, the ion mode state at the time of the final operation in the operation of the ion button 3 is maintained during the operation in the specific operation mode. Operation is controlled in ion mode. Thereby, the operation control by the ion mode in the final desired state intended by the user is executed. As a result, by operating the operation switching button 5 and selecting the operation mode, the operation control in the ion mode desired by the user can be realized. For this purpose, the ion button 3 is sequentially switched only by performing the operation mode switching operation. No need to operate. Therefore, troublesome operations are improved, operations can be simplified, and operability can be improved.

(Second Embodiment)
Next, a second embodiment will be described.

  In this embodiment, a case will be described in which a cut-off timer operation is performed based on the cold air fan 101 of the first embodiment described above.

  In the second embodiment, as in the first embodiment, when the operation on / off button 1 is pressed while the cold air blower 101 is stopped, the cold air operation is started. When the operation switching button 6 is pressed in the operation state, as described in the first embodiment, “cold air” operation, “clothing drying” operation, “automatic dehumidification” operation, “mold dehumidification” operation, “clothing deodorization” operation, The operation mode is switched and the operation is performed in each mode.

  Pressing the off timer button 2 while driving in any of the operation modes will set the off timer to 2 hours or 4 hours, and the off timer lamps “2 hours” and “4 hours” will light up accordingly, The off timer function operates. Initially, 2 hours are set. After that, every time the off timer button 2 is pressed, the setting changes from timer “2” time → timer “4” time → off timer release, and the off timer lamp is lit accordingly. From “2” to “4” and from “4” to off. When the operation on / off button 1 is pressed during operation, the cold air blower 101 stops all operations, and all the lamps that have been turned on are turned off.

  For comparison, the prior art off timer operation will be described with reference to FIG. In order to simplify the explanation, it is assumed that the cold air fan has already started operation.

  In step S101, it is monitored that the cut timer button 2 is pressed. When the off timer button 2 is pressed, if the original off timer setting is “cancel” (S102), it is switched to “2” (S103), and if it is “2” (S104), it is switched to “4” (S105). If it is “4” (S105), the off timer operation is canceled (S106). The off timer lamp lights for 2 hours when the off timer operation “2” is set, lights for 4 hours when “4” is set, and turns off when it is “released”. .

  In step S107, it is monitored that the operation on / off button is pressed again. When the operation on / off button is pressed again, the off timer operation is canceled (S108) and the operation is stopped (S109). If the operation on / off button is not pressed, the process proceeds to step S110, and it is determined whether the off timer operation is set.

  When the off timer operation is set, that is, when “2” or “4” is selected, the time after the off timer is set at step S111 is counted, and the set time has elapsed at step S112. Judge whether you are doing. When the time has elapsed, the off timer operation is canceled (S108) and the operation is stopped (S109). If the off timer time setting has not elapsed or the off timer operation is “released”, the operation is continued and the operation of the operation on / off button is monitored again.

  Regardless of whether or not the ion mode operation is performed in such control, the cool air blower is controlled to stop when the time set in the off timer operation elapses.

  Next, the cut-off timer operation of the present invention is a continuation of the control in FIG. 4 and will be described with reference to FIG. The corresponding part corresponds to the part after step S9.

  In step S9, it is monitored that the cut timer button is pressed. When the off timer button is pressed, if the original off timer setting is “cancel” (S10), it is switched to “2” (S10-1), and if it is “2” (S11), it is switched to “4” (S11). -1) If "4" (S11), the off timer operation is canceled (S12). The off timer lamp lights for 2 hours when the off timer operation “2” is set, lights for 4 hours when “4” is set, and turns off when it is “released”. .

  In step S13, it is monitored that the operation on / off button is pressed again. When the operation on / off button is pressed again, the off timer operation is canceled (S14) and the operation is stopped (S15). If the operation on / off button is not pressed, the process proceeds to step S16, and it is determined whether the off timer operation is set.

  When the off timer operation is set, that is, when “2” or “4” is selected, the time after the off timer is set at step S17 is counted, and the set time elapses at step S18. Judge whether you are doing. When the set time has elapsed, the timer operation is canceled (S19), and it is determined whether the operation mode is accompanied by the operation of the compressor (S20). When the operation of the compressor is involved, the operation of the compressor is stopped. Then, forcibly switch to the clothing deodorization mode and continue only the ion operation (S22). All operations are stopped when the compressor is not operated (S15). When the setting of the off timer time has not elapsed or when the off timer operation is “released”, the operation is continued as it is and the operation of the operation on / off button is monitored again.

  By performing such control, only the ion supply is continued in the indoor environment achieved by the cold air or the dehumidifying / drying operation when the timer operation ends in the specific operation mode. As a result, the compressor with high energy consumption is stopped and the operation of the refrigeration cycle is terminated, but the effects of sterilization and deodorization by the generation of ions are continued with the operation of only the blower and ion generator with low energy consumption. And enjoy it.

By setting a specific operation mode in equipment configured to exhibit the effects of sterilization, sterilization, deodorization, etc. by ions, it is necessary to ensure that ions are supplied, so that the original purpose of the equipment In addition, effects such as sterilization, sterilization, and deodorization by ions can be exhibited. In addition, it can be applied to devices that disperse medicines and distribute particles having a medicine effect in the same way.
