Description

  The present invention relates generally to an air cleaner, and more particularly to an air cleaner having a humidifying function and / or a dehumidifying function.

  Indoor air contains particulates and gases that are harmful to the human body, such as dust, pollen, and tobacco smoke. In recent years, as the air density of houses has increased, the degree of retention of these fine particles and gas in the room has increased, while the opportunity for active ventilation has decreased. Under such circumstances, air purifiers having a function of purifying indoor air are becoming widespread.

  In the conventional air cleaner, for example, when the blower is driven, the air in the air cleaning target room is taken into the air cleaner through the air filter. When air in the air-cleaning target room passes through the filter, particulates in the air are collected by the filter. At the same time, the air passing through the filter is purified by adsorbing or decomposing harmful gas contained in the air. There is also an air cleaner that includes an ion generator and purifies the air and then includes ions in the purified air. The air purified in this way is returned again from the air outlet of the air cleaner into the air cleaning target chamber.

  Some air purifiers have both a humidifying function and a dehumidifying function in order to adjust the air in the air-cleaning target room to a humidity comfortable for the user. For example, in an air purifier described in Japanese Patent Application Laid-Open No. 2008-35998 (Patent Document 1), air purified by passing through an air filter is further humidified by passing through a humidifying filter.

  In an air purifier having such a humidifying function, the user can usually select an air cleaning operation that performs air cleaning together with humidification and an air cleaning operation that performs air cleaning without humidification.

  Similarly, in the air cleaner with a dehumidifying function, it is possible to select an air cleaning operation in which air cleaning is performed together with dehumidification, and an air cleaning operation in which air cleaning is performed without performing dehumidification. Similarly, even an air purifier having both a humidifying function and a dehumidifying function is configured such that the user can select whether to perform humidification or dehumidification when performing air cleaning. An air purifier having a dehumidifying function may be used as a clothes dryer when the laundry is dried in a room.

  When using an air purifier with a dehumidifying function as a clothes dryer, if the user wants to finish drying the clothes while the user is out, the user can use the power off timer function to save power. It is desirable to stop the operation of the air purifier when an appropriate time has elapsed since the person instructed the operation to stop. Even in an air purifier having a humidifying function, the user can use the off timer function to stop the operation of the air purifier when an appropriate time has elapsed since the user instructed to stop the operation. .

  Japanese Patent Laying-Open No. 2005-315451 (Patent Document 2) describes an air conditioner having such a cut-off timer function. This air conditioner performs cooling operation or ventilation operation according to the air conditioning load in the room even after the end of the off timer. For example, if the outside air temperature is high after the end of the turn-off timer, the cooling operation is performed. Further, if the outside air temperature is low after the end of the turn-off timer, the engine is operated to perform ventilation.

JP 2008-35998 A JP 2005-315451 A

  However, in an air purifier having a humidifying function and / or a dehumidifying function, based on the humidity in the room after the end of the off-timer operation, as in the air conditioner described in JP-A-2005-315451 (Patent Document 2). Even if the humidifying operation or the dehumidifying operation is performed, the air in the air-cleaning target room cannot be purified.

  Accordingly, an object of the present invention is to provide an air purifier capable of purifying air even after the end of the timer operation.

  The air purifier according to the present invention includes an air purifying unit, a humidity adjusting unit, a control unit, an operation instruction unit, a time measuring unit, and an input unit.

  The air purifier cleans the air. The humidity adjusting unit humidifies and / or dehumidifies the air. The control unit controls driving of the air cleaning unit and the humidity adjusting unit. The operation instruction unit is an operation instruction unit for the user to select to stop the operation of the air cleaner. The timer unit starts measuring time when the user selects to stop the operation of the air cleaner by the operation instruction unit. The user inputs a timer time to be measured by the timer unit in the input unit.

  The control unit controls the air purifying unit and the humidity adjusting unit so that the driving of the humidity adjusting unit is stopped and the air purifying unit is continuously driven when the time measured by the time measuring unit passes the timer time. To do.

  If the user wants to continue humidification or dehumidification with the air purifier for a predetermined time after the user has selected to stop the operation of the air purifier through the operation instruction unit, the timer time is set as the predetermined time. In the input section.

  When the user inputs a timer time to the input unit and selects to stop the operation of the air cleaner by the operation instruction unit, the time measuring unit starts measuring time. When the time measured by the time measuring unit has passed the timer time, the control unit stops driving the humidity adjusting unit. When the driving of the humidity adjusting unit is stopped, humidification or dehumidification of air by the air cleaner is stopped. On the other hand, after the user selects to stop the operation of the air purifier, the time measured by the time measuring unit has elapsed the timer time, and the humidification or dehumidification of the air by the air purifier is stopped. After that, control is performed so that the air purifier is continuously driven.

  By doing in this way, the air cleaner which can purify air even after the end of a timer operation can be provided.

  In the air purifier according to the present invention, it is preferable that the air purifying unit includes an ion supply unit that supplies ions into the air cleaning target chamber. It is preferable that the control unit controls the ion supply unit so as to continue driving the ion supply unit when the time measured by the time measuring unit has passed the timer time.

  By supplying ions into the air-cleaning target room by the ion supply unit, it is possible to obtain deodorization and sterilization effects by the ions. Therefore, when the time measured by the time measuring unit has passed the timer time, the humidification or dehumidification of the air by the air purifier is stopped by controlling the ion supply unit so as to continue driving the ion supply unit. Later, the air in the air-cleaning target room can be kept clean by the effect of air purification by ions.

  In the air purifier according to the present invention, the control unit increases the amount of ions supplied by the ion supply unit into the air cleaning target chamber when the time measured by the time measuring unit has passed the timer time. Further, it is preferable to control the ion supply unit.

  When the humidity adjustment unit is a humidity adjustment unit that humidifies the air, the humidity adjustment unit is stopped, so that the humidification in the air-cleaning target room is stopped. For this reason, when the driving of the humidity adjusting unit is stopped, the humidity in the air-cleaning target room may be lower than when the humidity adjusting unit is driven. On the other hand, when the humidity adjusting unit is a humidity adjusting unit that dehumidifies air, the air is dehumidified while the humidity adjusting unit is being driven. It is considered that the humidity in the room is the lowest.

  In such a state where the humidity in the air-cleaning target room is low, even if ions are supplied to the air-cleaning target room, effects such as sterilization, sterilization, and deodorization by ions can be sufficiently obtained as compared with a state where the humidity is high. There may not be.

  Therefore, when the time measured by the time measuring unit passes the timer time and the driving of the humidity adjusting unit is stopped, the ion supply unit increases the amount of ions supplied into the air-cleaning target chamber. Control the supply section. By doing in this way, the effect of ions can be maintained similarly to the case where the humidity adjusting unit is driven regardless of the humidity in the air.

  In the air purifier according to the present invention, the air purifier preferably includes a blower that sends out air. It is preferable that the control unit controls the air blowing unit so that the output of the air blowing unit is minimized when the time measured by the time measuring unit has passed the timer time.

  In an air cleaner, the power consumed by the blower is relatively large among the members. Therefore, when the time measured by the time measuring unit has passed the timer time, the air blowing unit is controlled so as to minimize the output of the air blowing unit to save power. On the other hand, even if the output of the air blowing unit is lowered to reduce the air blowing amount, the ion supply amount by the ion supplying unit is increased so that the ions are sufficiently supplied into the air cleaning target chamber. By doing in this way, regardless of the humidity in the air, as in the case where the humidity adjusting unit is driven, it is possible to maintain the high effect of sterilization and deodorization by ions.

  The air cleaner according to the present invention preferably includes a selection unit for the user to select driving and stopping of the air cleaning unit. When the user selects the driving stop of the air cleaning unit by the selection unit, the control unit preferably stops driving the air cleaning unit when the time measured by the time measuring unit has passed the timer time.

  In this way, when it is not necessary to continue air cleaning after the timer time has elapsed, all operations are stopped in the same manner as conventional air purifiers to prevent energy waste. it can.

  As described above, according to the present invention, it is possible to provide an air purifier capable of purifying air even after the end of the off timer operation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
As shown in FIG. 1, the air cleaner 1 having a humidifying function is entirely covered with a main body 2 and a front panel 3. The air cleaner 1 is used in a state of being placed on the floor or being hung on a wall. The main body 2 is formed in the shape of a flat, substantially rectangular parallelepiped box, and is disposed in the air-cleaning target room with the bottom surface being level with the floor surface. The front side of the main body 2 is covered with a front panel 3.

  A hook (not shown) that engages with the upper portion of the main body 2 is formed on the upper surface of the rear surface of the front panel 3. Engaging portions 7 are formed at the lower portions of the left and right side surfaces of the front panel 3. By hooking the hook on the upper part of the main body 2 so that the front panel 3 is hung from the main body 2, the engaging portion 7 is engaged with the main body 2. It attaches to the main body 2 in the state which opened the clearance gap. The gap between the main body 2 and the front panel 3 formed in this way is formed on the left and right sides and the lower side of the main body 2. Therefore, the inside of the main body 2 communicates with the outside on both the left and right sides and the lower side of the main body 2. As will be described later, air outside the main body 2 is sucked into the main body 2 from the gap.

  A water supply tank 16 is attached to the lower part of the main body 2. A tray 15 is disposed at the bottom of the main body 2 below the water supply tank 16. The user can remove the water supply tank 16 from the main body 2. The user removes the water supply tank 16 from the main body 2 and supplies water to the water supply tank 16 before attaching the main body 2 before starting the operation of the air purifier 1. When the water supply tank 15 is attached to the main body 2, a part of the water in the water supply tank 16 is stored in the tray 15.

  An upper outlet 11 is formed on the back side of the upper surface of the main body 2. A front outlet 12 is formed on the front side of the upper surface of the main body 2. On the upper surface of the main body 2, an operation / display unit 13 is disposed between the upper outlet 11 and the front outlet 12.

  As shown in FIG. 2, the operation / display unit 13 includes an operation on / off button 60, a humidification on / off button 61, an air volume switching button 63, a turn-off timer button 65, a sterilization ion on / off button 67, and a turn-off timer switch. It is constituted by an operation button 48 constituted by a button group of the switch 69 and a lamp group of a humidifying lamp 62, an air volume lamp 64, a turn-off timer lamp 66, a sterilization ion lamp 68, a clean sign lamp 70, and a water supply lamp 71 And a display lamp 49. Each button and lamp will be described later. The operation button 48 and the display lamp 49 are collective nouns and do not mean a single button or lamp.

  As shown in FIG. 3, on the front side of the air cleaner 1, a filter housing portion in which the deodorizing filter 4 and the dust collection filter 5 are housed is formed inside the main body 2. The filter storage portion is formed as a rectangular parallelepiped recess. The filter housing portion is covered with the front panel 3. The filter storage unit stores a deodorizing filter 4 and a dust collection filter 5 in order from the side close to the front panel 3, that is, from the front side of the air cleaner 1.

  The deodorizing filter 4 has a non-woven fabric made of polyester attached to a rectangular frame, activated carbon is uniformly distributed on the non-woven fabric, and a non-woven fabric made of polyester is further covered thereon. The deodorizing filter 4 adsorbs acetaldehyde, ammonia, acetic acid and the like which are odor components in the air.

  The dust collection filter 5 is a so-called HEPA (High Efficiency Particular Air) filter. The dust collecting filter 5 is made by combining an aggregate made of polyester / vinylon non-woven fabric with a melt blown non-woven fabric processed with a stone, and folding it. A frame made of a non-woven fabric with a hot melt is welded. The dust collection filter 5 collects fine dust.

  The dust collection filter 5 and the deodorizing filter 4 inserted in the filter storage unit are prevented from dropping by the filter pressing frame 6 attached to the opening of the filter storage unit. The filter holding frame 6 is a front shape rectangle, and a large number of ventilation holes are formed.

  A blower 8 is disposed behind the filter housing portion of the main body 2 with a partition wall 21 therebetween. The blower 8 includes a fan motor 9 and a fan 10. The partition wall 21 on the front side of the blower 8, the partition wall 22 surrounding the outer periphery, and the partition wall 23 on the back side constitute a fan casing. The fan motor 9 is fixed to the partition wall 21. The partition wall 23 on the back side is formed with an intake port composed of a large number of small holes. Although a turbo fan is shown as the fan 10 in FIG. 3, the fan 10 is not limited to a turbo fan, and a propeller fan or a cross flow fan can be used. In the case of the turbo fan shown in FIG. 3, a device is devised in which the thickness is made larger than the fan diameter, and the noise level is lowered by lowering the rotational speed. In this embodiment, the fan motor 9 is a direct current motor with emphasis on controllability.

  A partition wall 22 surrounding the outer periphery of the fan 10 has an involute curve shape, and guides air discharged from the outer periphery of the fan 10 to two air outlets formed in the upper portion of the main body 2. The upper blower outlet 11 is provided on the upper surface of the blower 8 so that air is sent upward, and the front blower outlet 12 is forward of the upper blower outlet 11 and air is sent obliquely upward. It is provided as follows. A flow path is formed in the main body 2 for the air sent out by the fan 10 to flow toward the front outlet 12. An ion generator 17 is disposed in the vicinity of the end of the flow path communicating with the front outlet 12 on the blower 8 side.

  An opening 24 is formed below the partition wall 21. The opening 24 serves as an inlet to the first ventilation path 31 and the second ventilation path 32 formed below the partition wall 22. The first ventilation path 31 and the second ventilation path 32 are separated by a horizontal partition wall 27. The first air passage 31 is formed below the partition wall 27, and the second air passage 32 is formed on the partition wall 27. Between the partition wall 23 and the back wall 25 of the main body 2, there is a gap that leads to an air inlet provided in the partition wall 23, and the first ventilation path 31 and the second ventilation path 32 are on the back side of the air purifier 1. In FIG. 2, the gap is connected in the vicinity of the end of the partition wall 27. A protrusion is formed as a contact point 26 on the inner side of the back wall 25 and above the partition wall 27.

  The humidification filter 14 is disposed in the first ventilation path 31. The humidifying filter 14 is made of a water-absorbing material folded in a zigzag, and completely blocks the first air passage 31. The lower end of the humidifying filter 14 is received by the tray 15 disposed at the bottom of the first air passage 31. The tray 15 can be taken in and out from one side of the main body 2, and water is stored inside. When the humidifying filter 14 sucks up the water in the tray 15 by capillary action, the humidifying filter 14 becomes wet. A water supply tank 16 (FIG. 1) attached to one side of the main body 2 supplies water to the tray 15. The combination of the tray 15 and the water supply tank 16 constitutes a humidifying water supply unit.

  A damper 35 is disposed in the second ventilation path 32. The damper 35 is fixed to a support shaft 36 disposed slightly above the second air passage 32, and is formed in an arc shape centering on the support shaft 36. In the damper 35, a protrusion 37 is formed at the end on the partition wall 27 side. The support shaft 36 is rotated by a motor (not shown). The damper 35 rotates in the vertical plane as the support shaft 36 rotates. The motor that rotates the support shaft 36 is a digital control motor such as a stepping motor, and the rotation angle of the damper 35 is always recognized.

  FIG. 3 shows a state where the damper 35 closes the second ventilation path 32. When the blower 8 is driven, an air current as shown by the two-dot chain line arrow in FIG. 3 is generated. Air outside the air cleaner 1 enters the front surface of the filter housing portion through the gap between the front panel 3 and the main body 2 and is sucked into the deodorizing filter 4 from the vent of the filter holding frame 6. The air in which the odor component is adsorbed by the deodorizing filter 4 is sucked into the dust collecting filter 5 and is collected up to fine dust. Since the second air passage 32 is closed by the damper 35, the purified air that has passed through the dust collection filter 5 passes exclusively through the first air passage 31 where it is humidified by the humidifying filter 14. The deodorized, purified and humidified air rises through the gap between the partition wall 23 and the back wall 25 and is sucked into the center of the fan 10 from the air inlet provided in the partition wall 23. The air discharged from the fan 10 is blown out into the room from the upper outlet 11 and the front outlet 12. If the ion generator 17 is operated, the ions generated by the ion generator 17 are sent out into the room mainly on the air current blown out from the front outlet 12. As described above, when the air cleaner 1 is operated and the blower 8 is driven in the state shown in FIG. 3, a humidified air cleaning operation, that is, an operation in which air is cleaned while humidifying is performed.

  In this embodiment, the deodorizing filter 4, the dust collection filter 5, the blower 8, the ion generator 17, and the damper 35 constitute an air purifying unit. The blower 8, the humidifying filter 14, and the damper 35 constitute a humidity adjusting unit.

  As shown in FIG. 4, the ion generator 17 is entirely covered with a housing 171 in which two openings are formed. Two openings formed in the housing 171 are a positive ion discharge port 172 and a negative ion discharge port 173. A positive ion generator 174 and a negative ion generator 175 are arranged inside the housing 171 at the positive ion outlet 172 and the negative ion outlet 173, respectively. Both the positive ion generator 174 and the negative ion generator 175 are formed by needle-like discharge electrodes.

  As shown in FIG. 5, a high voltage is applied to the positive ion generator 174 and the negative ion generator 175 of the ion generator 17 (FIG. 4). When a high voltage is applied to the positive ion generation unit 174 and the negative ion generation unit 175, discharge occurs in the positive ion generation unit 174 and the negative ion generation unit 175, and positive ions (positive ions) and negative ions (negative ions). Occurs.

The positive ions generated most stably in the ion generator 17 are H ⁺ (H ₂ O) _n , and the negative ions generated most stably are O ₂ ⁻ (H ₂ O) _m . These positive ions and negative ions alone have no particular sterilizing effect on airborne bacteria. However, these positive ions and negative ions are generated at the same time and interact with each other, whereby hydrogen peroxide H ₂ O ₂ or hydroxyl radical (.OH) as an active species is generated by a chemical reaction. H ₂ O ₂ or (.OH) has a strong activity. Bacteria floating in the air can be removed by the activity of H ₂ O ₂ or (.OH) generated by the chemical reaction between the positive ion and the negative ion.

  The positive ions generated by the positive ion generator 174 of the ion generator 17 and the negative ions generated by the negative ion generator 175 are caused by the flow of air passing through the ion generator 17 and the negative ion release port 172. It is discharged from the outlet 173 to the outside of the housing 171. Positive ions and negative ions released to the outside of the casing 171 move in the main body 2 toward the front outlet 12 and are supplied from the front outlet 12 into the air-cleaning target chamber. The ion generator 17 and the blower 8 are an example of an ion supply unit.

  When the damper 35 is rotated from the state shown in FIG. 3 to the state shown in FIG. 6 and the air cleaner 1 is operated, an air cleaning operation is performed in which air purification is performed without humidification.

  As shown in FIG. 6, the damper 35 is rotated until the projection 37 contacts the contact point 26 on the inner surface of the back wall 25. In the state shown in FIG. 6, the second ventilation path 32 is opened, and the outlet of the first ventilation path 31 is closed. When the blower 8 is driven in this state, the air passing through the deodorizing filter 4 and the dust collecting filter 5 is sucked into the blower 8 without passing through the humidifying filter 14. Therefore, air that has been deodorized and cleaned but not humidified is blown into the room.

  Next, the control-related structure of the air cleaner 1 is demonstrated. As illustrated in FIG. 7, sensors such as a temperature sensor 41, a humidity sensor 42, a dust sensor 43, and an odor sensor 44 transmit signals to the control unit 40. Further, the tray water level detection switch 45, the operation button 48, and the power supply synchronization signal generation circuit 54 also transmit signals to the control unit 40. The timing unit 53 transmits and receives signals to and from the control unit 40. The control unit 40 transmits a control signal to the display lamp 49, the damper motor drive circuit 50, the fan motor drive circuit 51, and the ion generator drive circuit 52 based on the signals received from these sensors and the like.

  The temperature sensor 41 measures the temperature of the air in the air-cleaning target room. The humidity sensor 42 measures the humidity of the air in the air-cleaning target room. The temperature sensor 41 and the humidity sensor 42 may be integrated as a temperature / humidity sensor. The dust sensor 43 is a combination of a light emitting element and a light receiving element, and detects dust particles floating in the air in the air-cleaning target room. The odor sensor 44 is made of a metal oxide semiconductor, and detects the odor component by utilizing the fact that the resistance value changes when gas is adsorbed. The dust sensor 43 and the odor sensor 44 function as a dirt detector that knows how dirty the air is in the air-cleaning target room.

  The tray water level detection switch 45 detects that the water level in the tray 15 has dropped and the water level has become “water shortage”. When it is detected that the water level in the tray 15 has become “water shortage”, the water supply from the water supply tank 16 to the tray 15 is no longer performed, that is, the water supply tank 16 becomes empty. Means that. That is, the tray water level detection switch 45 functions as a water level detection means of the humidifying water supply unit.

  The power supply synchronization signal generation circuit 54 performs half-wave rectification on the AC waveform of the commercial power supply, shapes the waveform using a transistor or the like, and generates a rectangular wave synchronized with the 60 Hz or 50 Hz AC waveform. The control unit 40 can monitor the rectangular wave to determine the power supply frequency or detect the interruption of energization.

  The operation buttons 48 include a plurality of buttons as shown in FIG. 2, and a signal is transmitted to the control unit 40 when the user operates each button. In addition, a control signal is transmitted from the control unit 40 that has received the signal to each of the lamps constituting the display lamp 49.

  When the user presses the operation on / off button 60 and puts the operation on / off button 60 in the “on” state when the air cleaner 1 is stopped, a signal is transmitted to the control unit 40 and the air The air cleaning operation of the cleaner 1 is started. The user stops driving of the air purifier 1 by pressing the operation on / off button 60 while the air purifier 1 is in operation to set the operation on / off button 60 to the “off” state. Can be selected. The operation on / off button 60 is an example of an operation instruction unit.

  When the user presses the humidification on / off button 61 to “on” while the air purifier 1 is in operation, a signal is transmitted to the control unit 40. The control unit 40 transmits a control signal to the humidification lamp 62 of the display lamp 49 so that the humidification lamp 62 is turned on. The control unit 40 transmits a control signal to the damper motor drive circuit 50 to control the damper 35 (FIGS. 3 and 6) so as to be in the state shown in FIG. In this way, the humidified air cleaning operation is started. On the other hand, if the humidification / off button 61 is pressed during the humidified air cleaning operation, that is, while the humidification lamp 62 is lit, and the humidification is turned off, the control unit 40 transmits a control signal to the humidification lamp 62. Then, it is turned off, and a control signal is transmitted to the damper motor drive circuit 50 to control the damper 35 (FIGS. 3 and 6) so as to be in the state shown in FIG. In this way, an air cleaning operation without humidification is performed.

  When the off timer button 65 is pressed during the humidified air cleaning operation or the air cleaning operation without humidification, a signal is transmitted to the control unit 40. The control unit 40 transmits a control signal to the turn-off timer lamp 66, and turns on the turn-off timer lamp 66. In addition, the control unit 40 transmits a control signal to the time measuring unit 53, and the off timer function operates. When the user presses the off timer button 65, the off timer time is initially set to 2 hours as the timer time. Thereafter, each time the user presses the off timer button 65, the off timer time is changed from 2 hours to 4 hours and from 4 hours to 8 hours. When the user presses the off timer button 65 when the off timer time is set to 8 hours, the off timer function is changed to release. The lighting state of the off timer lamp 66 changes from “2” to “4”, from “4” to “8”, and from “8” to off according to the off timer time. The off timer button 65 is an example of an input unit.

  When the sterilization ion on / off button 67 is pressed during either the air cleaning operation or the humidified air cleaning operation, a signal is transmitted to the control unit 40. The control unit 40 transmits a control signal to the sterilization ion lamp 68 to light the sterilization ion lamp 68. Further, the control unit 40 transmits a control signal to the ion generator drive circuit 52 to start the operation of the ion generator 17. When the sterilization ion on / off button 67 is pressed again, the control unit 40 stops driving the ion generator 17 and turns off the sterilization ion lamp 68.

  The switch-off timer changeover switch 69 indicates whether the user stops only the humidification or all functions when the switch-off timer time has elapsed since the user selected to stop the operation of the air purifier 1. This is a switch for selecting. When stopping only humidification, the user slides the switch to “humidification only”. To stop all functions, the user slides the switch to “all stop”. When the off timer changeover switch 69 is operated, a signal is transmitted to the control unit 40. The control unit 40 transmits a control signal to the damper motor drive circuit 50, the fan motor drive circuit 51, and the ion generator drive circuit 52 based on the signal received from the turn-off timer changeover switch 69. The off timer selector switch 69 is an example of a selection unit.

  The clean sign lamp 70 is lit in a different color when the control unit 40 that has received the detection results of the dust sensor 43 and the odor sensor 44 functioning as a dirt detector transmits a control signal. That is, for example, when the air in the air-cleaning target room is small, the light is turned on in green, when slightly dirty, the light is turned on in yellow, and when the dirt becomes severe, the light is turned on in red.

  The degree of indoor air contamination is a factor for determining the air volume when the air cleaning operation is performed “automatically”. That is, for example, if the dirt becomes severe, as much room air as possible is passed through the air cleaner 1 within a unit time to be purified. Based on the signals received from the dust sensor 43 and the odor sensor 44, the control unit 40 transmits a control signal to the fan motor drive circuit 51 to change the air volume from “low” to “medium” and from “medium” to “strong”. Change.

  In the case of the humidified air cleaning operation, the humidity in the air cleaning target room is also an air volume determining factor when the humidified air cleaning operation is performed “automatically”. That is, for example, if the humidity of the air in the air-cleaning target room decreases, as much room air as possible passes through the air purifier 1 within a unit time and is humidified. The control unit 40 transmits a control signal to the fan motor drive circuit 51 to change the air volume from “weak” to “medium” and from “medium” to “strong”.

  When the tray water level detection switch 45 detects that the water level in the tray 15 has dropped and the water level is “water shortage”, a signal is transmitted to the control unit 40. The control unit 40 transmits a control signal to the water supply lamp 71 to blink the water supply lamp 71 and prompt the user to supply water.

  The timer 53 is based on a signal transmitted from the controller 40 when the operation on / off button 60 of the operation button 48 is operated to stop the operation of the air cleaner 1 by the user. To measure the off timer time. The time measuring unit 53 transmits a signal to the control unit 40 when measuring the off timer time.

  In the air cleaning operation or the humidified air cleaning operation, the air volume is changed every time the air volume switching button 63 is pressed. As shown in FIG. 8, in step S001, the control unit checks whether or not the air volume switching button 63 is set to “ON”. If the air volume switching button 63 is set to “ON”, the process proceeds to step S002. If the air volume switching button 63 is not “ON”, the process proceeds to step S008.

  In step S002, the control unit 40 determines whether or not the air volume switching button 63 has been operated. If the air volume switching button 63 is not operated, the process proceeds to step S003. If the air volume switching button 63 is operated, the process proceeds to step S004. In step S003, the control unit 40 transmits a control signal to the fan motor drive circuit 51 to make the air flow rate of the blower 8 relatively strong.

  In step S004, the control unit 40 determines whether or not the air volume switching button 63 has been operated. If the air volume switching button 63 is not operated, the process proceeds to step S005. If the air volume switching button 63 is operated, the process proceeds to step S006. In step S005, the control unit 40 transmits a control signal to the blower 8 to set the air volume to “medium” which is relatively weaker than “strong”.

  In step S006, the control unit 40 determines whether or not the air volume switching button 63 has been operated. If the air volume switching button 63 is not operated, the process proceeds to step S007. If the air volume switching button 63 is operated, the process proceeds to step S008. In step S007, the control unit 40 transmits a control signal to the blower 8 to make the air volume “weak” which is relatively weaker than “medium”.

  In step S008, the control unit 40 determines whether or not the air volume switching button 63 has been operated. If the air volume switching button 63 is not operated, the process proceeds to step S009. If the air volume switching button 63 is operated, the process returns to step S003. In step S009, the control unit 40 controls the air volume “automatically”.

  As described above, when the user operates the air volume switching button 63, the air volume is changed to "automatic", "strong", "medium", and "weak". The lighting state of the air volume lamp 64 changes from “automatic” to “strong”, “strong” to “medium”, “medium” to “weak”, and “weak” to “automatic” according to the air volume. Further, the air cleaning operation and the humidified air cleaning operation remember the mode of the previous operation regardless of the user's operation, and may be started by the humidified air cleaning operation.

  Operation | movement of the air cleaner 1 comprised as mentioned above is demonstrated. The process from turning on the power of the air cleaner 1 to stopping the operation will be described with reference to FIGS. 1 to 11. In the flowcharts shown in FIG. 9 to FIG.

  In step S <b> 101, the user inserts the plug into an outlet and turns on the air cleaner 1. In step S102, initial setting at power-on is performed, the humidification mode is set to “ON”, and the OFF timer is set to “RELEASE”. Thereafter, the air cleaner 1 enters a standby state.

  In step S103, the control unit 40 determines whether or not the operation button is set to “ON”. If the operation button is not “ON”, the process returns to step S103. If the user presses the driving on / off button 60 and the driving button is set to “ON”, the process proceeds to step S104.

  In step S104, the operation of the air cleaner 1 is started. When the operation of the air cleaner 1 is started, the lamp corresponding to each mode is turned on.

  In step S105, the control unit 40 determines whether or not the humidification on / off button 61 has been pressed. If the humidification on / off button 61 is pressed, the process proceeds to step S106. If the humidification on / off button 61 is not pressed, the process proceeds to step S109 in FIG.

  In step S106, the control unit 40 initially determines whether or not the humidification mode is “ON”. If the initial humidification mode is “ON”, the process proceeds to step S107, the humidification mode is set to “OFF”, and the humidification lamp 62 is turned off. If the initial humidification mode is not “ON”, that is, if the initial humidification mode is “OFF”, the process proceeds to step S108, the humidification mode is set to “ON”, and the humidification lamp 62 is turned on. Thereafter, the process proceeds to step S109. If the humidification on / off button 61 is not pressed in step S105, the humidification mode remains at the initial setting.

  In step S109, the control unit 40 determines whether or not the off timer button 65 is “ON”. If the off timer button 65 is set to “ON”, the process proceeds to step S110. If the off timer button is not “ON”, the process proceeds to step S119.

  In step S110, the control unit 40 determines whether or not the off timer button 65 has been operated. If the off timer button 65 is operated, the process proceeds to step S113. If the off timer button 65 is not operated, the process proceeds to step S111.

  In step S111, the control unit 40 transmits a control signal to the time measuring unit 53, and sets the off timer time to 2 hours. Thereafter, the process proceeds to step S112, the two-hour lamp of the off timer lamp 66 is turned on, and then the process proceeds to step S120 in FIG.

  In step S113, the control unit 40 determines whether or not the off timer button 65 has been operated. If the off timer button 65 is operated, the process proceeds to step S116. If the off timer button 65 is not operated, the process proceeds to step S114.

  In step S114, the control unit 40 transmits a control signal to the time measuring unit 53, and sets the off timer time to 4 hours. Thereafter, the process proceeds to step S115, the lamp of the off timer lamp 66 is turned on for 4 hours, and then the process proceeds to step S120 in FIG.

  In step S116, the control unit 40 determines whether or not the off timer button 65 has been operated. If the off timer button 65 is operated, the process proceeds to step S119. If the off timer button 65 is not operated, the process proceeds to step S117.

  In step S117, the control unit 40 transmits a control signal to the time measuring unit 53, and sets the off timer time to 8 hours. Thereafter, the process proceeds to step S118, and the 8-hour lamp of the off timer lamp 66 is turned on, and then the process proceeds to step S120 in FIG.

  In step S119, the off timer is canceled and all off timer lamps 66 are extinguished. Then, it progresses to step S120 of FIG.

  As shown in FIG. 11, in step S <b> 120, the control unit 40 determines whether or not the operation on / off button 60 has been pressed and turned “off”. If the operation on / off button 60 is set to “OFF”, the process proceeds to step S121. If the operation on / off button 60 is not set to “OFF”, the process returns to step S105 in FIG.

  In step S121, the control unit 40 determines whether or not the off timer is cancelled. If the off timer is released, the process proceeds to step S129. If the off timer is not released, the process proceeds to step S122.

  In step S122, the control unit 40 transmits a control signal to the time measuring unit 53 to start measuring time.

  In step S123, the control unit 40 determines whether or not the time measured by the time measuring unit 53 has passed the cut-off timer time based on the signal received from the time measuring unit 53. If the time measured by the time measuring unit 53 has passed the cut-off timer time, the process proceeds to step S124. If the time measured by the time measuring unit 53 has not expired, the process returns to step S105 in FIG.

  In step S124, the control unit 40 determines whether or not the off timer changeover switch 69 is operated and is set to “all stop”. If the off timer selector switch 69 is not set to “all stop”, the process proceeds to step S125. If the off timer selector switch 69 is set to “all stop”, the process proceeds to step S128.

  In step S125, the control unit 40 controls to release the off timer operation. In step S126, the control unit 40 controls the damper 35 so that the humidification is set to the “off” mode. In step S137, the ion generator drive circuit 52 is controlled to increase the amount of ions. Thereafter, the process returns to step S105 in FIG.

  By doing in this way, only after the expiration | time-off timer time passes, only a humidification driving | operation can be stopped and an air purifying driving | operation can be performed continuously. The amount of ions generated from the ion generator 17 increases with the elapse of the off timer time. In order to increase the amount of ions, the output voltage of the ion generator drive circuit 52 is increased, or the output pulse of the ion drive circuit is increased.

  The reason why the amount of ions is increased by these methods is that the energy given to the discharge electrode is increased. Alternatively, the rotation speed of the fan motor 9 is increased in order to increase the amount of air passing through the ion generator 17. This is because the amount of ions generated in the immediate vicinity of the discharge electrode is very large, so the amount of ions delivered to the space substantially increases just by increasing the amount of blown air, and the amount of generated ions itself increases. This is because it has an effect.

  On the other hand, in step S128, the control unit 40 cancels the off timer operation. In step S129, the damper motor drive circuit 50, the fan motor drive circuit 51, and the ion generator drive circuit 52 are controlled so that the humidification function and the air purification function are stopped as in the conventional air purifier. Thereafter, the process returns to step S103 in FIG.

  In this embodiment, the slide switch is used as the switch-off timer changeover switch. However, the conventional operation of the button existing in the operation unit (long press, multiple simultaneous presses) causes the conventional switch after the switch-off timer time has elapsed. It may be switched whether the air purifying function is stopped as in an air purifier.

  As shown in FIG. 12, the operation of the air cleaner 1 may proceed to step S <b> 130 after step S <b> 127 shown in FIG. 11.

  In step S <b> 130, the control unit 40 sets the air volume to “weak” and controls the fan motor drive circuit 51 to rotate the blower 8 at the lowest output and the lowest speed. Thereafter, the process returns to step S105 in FIG. The other steps of the flowchart of FIG. 12 are the same as the steps of the flowchart shown in FIG.

  As described above, the air cleaner 1 according to the first embodiment includes the air purifying unit, the humidity adjusting unit, the control unit 40, the operation on / off button 60, the time measuring unit 53, and the off timer button 65. Prepare.

  The air purifier cleans the air. The humidity adjusting unit humidifies the air. The control unit 40 controls driving of the air cleaning unit and the humidity adjusting unit. The operation on / off button 60 is an operation on / off button 60 for the user to select to stop the operation of the air purifier 1. The timer 53 starts measuring time when the user selects to stop the operation of the air cleaner 1 by the operation on / off button 60. A user inputs a timer time to be measured by the timer 53 to the off timer button 65.

  When the time measured by the time measuring unit 53 has passed the timer time, the control unit 40 stops driving the humidity adjustment unit and continues to drive the air purification unit and the humidity adjustment unit. To control.

  If the user wants to continue humidification with the air cleaner 1 for a predetermined time after the user has selected to stop the operation of the air cleaner 1 through the operation on / off button 60, the user can continue the predetermined time. The timer time is input to the off timer button 65 as follows.

  When the user inputs a timer time to the turn-off timer button 65 and selects to stop the operation of the air purifier 1 with the operation on / off button 60, the time measuring unit 53 starts measuring time. When the time measured by the time measuring unit 53 has passed the timer time, the control unit 40 stops driving the humidity adjusting unit. When the driving of the humidity adjusting unit is stopped, the humidification of the air by the air cleaner 1 is stopped. On the other hand, after the user has selected to stop the operation of the air purifier 1, the control unit 40 continues to drive the air cleaning unit even if the time measured by the time measuring unit 53 has elapsed the timer time. To control. In this way, the air in the air-cleaning target room can be kept clean even after air humidification by the air cleaner 1 is stopped.

  By doing in this way, the air cleaner 1 which can clean air even after completion | finish of a cut-off timer operation can be provided.

  In the air purifier 1, the air purifier includes an ion generator 17 and a blower 8 that supply ions into the air purification target chamber. The control unit 40 controls the ion generator 17 and the blower 8 so as to continue driving the ion generator 17 and the blower 8 when the time measured by the time measuring unit 53 has passed the timer time.

  By supplying ions into the air-cleaning target chamber by the ion generator 17 and the blower 8, deodorization and sterilization effects by the ions can be obtained. Therefore, the air cleaner 1 is controlled by controlling the ion generator 17 and the blower 8 so as to continue driving the ion generator 17 and the blower 8 when the time measured by the time measuring unit 53 has passed the timer time. Even after the humidification of the air by is stopped, the air in the air-cleaning target room can be kept clean by the effect of the air purification by ions.

  Moreover, in the air cleaner 1, the control part 40 is the quantity of the ion supplied in the air purification object room | chamber by the ion generator 17 and the air blower 8, when the time measured by the time measuring part 53 passes timer time. The ion generator 17 and the blower 8 are controlled so as to increase.

  When the humidity adjustment unit is a humidity adjustment unit that humidifies the air, the humidity adjustment unit is stopped, so that the humidification in the air-cleaning target room is stopped. For this reason, when the driving of the humidity adjusting unit is stopped, the humidity in the air-cleaning target room may be lower than when the humidity adjusting unit is driven.

  In such a state where the humidity in the air-cleaning target room is low, even if ions are supplied to the air-cleaning target room, effects such as sterilization, sterilization, and deodorization by ions can be sufficiently obtained as compared with a state where the humidity is high. There may not be.

  Therefore, when the time measured by the time measuring unit 53 has passed the timer time, the ion generator 17 and the blower are configured to increase the amount of ions supplied into the air cleaning target chamber by the ion generator 17 and the blower 8. By controlling 8, the effect of ions can be maintained in the same manner as when the humidity adjusting unit is driven regardless of the humidity in the air.

  Moreover, in the air cleaner 1, the air-cleaning part contains the air blower 8 which sends out air. The control unit 40 controls the blower 8 so as to make the output of the blower 8 the lowest when the time measured by the time measuring unit 53 has passed the timer time.

  In the air cleaner 1, the power consumed by the blower 8 among the members is often relatively large. Therefore, when the time measured by the time measuring unit 53 has passed the timer time, the blower 8 is controlled to make the output of the blower 8 the lowest so as to save power. On the other hand, even if the output of the blower 8 is lowered and the amount of blown air is reduced, the supply amount of ions by the ion generator 17 is increased so that ions are sufficiently supplied into the air target chamber. By doing in this way, regardless of the humidity in the air, as in the case where the humidity adjusting unit is driven, it is possible to maintain the high effect of sterilization and deodorization by ions.

  Moreover, the air cleaner 1 is provided with the switch-off timer changeover switch 69 for a user to select the drive and drive stop of an air purifying part. When the user selects to stop the driving of the air cleaning unit with the switch-off timer changeover switch 69, the control unit 40 stops driving the air cleaning unit when the time measured by the time measuring unit 53 has passed the timer time. To do.

  By doing in this way, when it is not necessary to continue the air cleaning after the timer time elapses, all the operations are stopped similarly to the conventional air purifier 1 to prevent waste of energy. Can do.

  The air cleaner 200 is provided with a deodorizing filter and a dust collecting filter in the filter housing portion of the main body 201 as in the air cleaner 1 of the first embodiment. The deodorizing filter, the dust collecting filter, the cool air blower 214, the hot air blower 215, and the ion generator 217 constitute an air cleaning unit. The ion generator 217, the cool air blower 214, and the hot air blower 215 constitute an ion supply unit.

  The cool air blower 214 and the warm air blower 215 are configured by a fan motor and a fan, similarly to the blower 8 (FIG. 3) of the first embodiment.

  The outlet of the hot air blower 215 is formed to face upward. A damper 216 for switching the air blowing direction between the front side and the rear side is arranged above the hot air blower 215. An ion generator 217 is disposed between the damper 216 and the air outlet 202.

  The damper 216 is fixed to a support shaft (not shown) disposed above the blower 8 in the air passage, and is formed in an arc shape centered on the support shaft. The spindle is rotated by a motor (not shown). The damper 216 is rotated in the vertical plane with the rotation of the support shaft. The motor that rotates the spindle is a digital control motor such as a stepping motor, and the rotation angle of the damper 216 is always recognized.

  The ion generator 217 is the same as the ion generator 17 provided in the air cleaner 1 of the first embodiment.

  When the hot air blower 215 is driven, an air flow as shown by a dashed-dotted arrow in FIG. 13 is generated. Air outside the air cleaner 200 is sucked into the main body 201 from a front panel (not shown). The air sucked into the main body 201 passes through a ventilation path formed on the back side in the main body 201 and is blown out from the air outlet 202 into the air purification target chamber.

  When the ion generator 217 is driven, the ions generated by the ion generator 217 are sent out into the air purification target room mainly on the air current blown out from the outlet 202.

  As shown in FIG. 14, the operation / display unit 213 of the air purifier 200 of the second embodiment is different from the operation / display unit 13 (FIG. 2) of the air purifier 1 of the first embodiment. The button 248 includes a dehumidification on / off button 261 instead of the humidification on / off button 61, and a off timer changeover switch 269 instead of the off timer changeover switch 69. In addition, the display lamp 249 includes a dehumidification lamp 262 instead of the humidification lamp 62, and a drain lamp 271 instead of the water supply lamp 71. Other configurations of the operation / display unit 213 of the air cleaner 200 of the second embodiment are the same as those of the operation / display unit 13 of the air cleaner 1 of the first embodiment.

  As shown in FIG. 15, the control-related configuration of the air purifier 200 is different from the air purifier 1 of the first embodiment shown in FIG. A detection switch 245 is provided, an operation button 248 is provided instead of the operation button 48, and a display lamp 249 is provided instead of the display lamp 49. In addition, a refrigeration cycle drive circuit 255 is provided. The fan motor drive circuit 251 drives the cool air blower 214 and the hot air blower 215 shown in FIG.

  The drain tank water level detection switch 245 transmits a control signal to the control unit 40 when the water level in the drain tank 218 (FIG. 13) becomes full. The control unit 40 that has received the signal from the drain tank water level detection switch 245 informs the user that the drain tank 218 is full by blinking the drain lamp 271 (FIG. 14) of the display lamp 249, for example. Encourages people to drain.

  When the user presses the dehumidification on / off button 261 to turn on dehumidification while the air purifier 200 is in operation, a signal is transmitted to the control unit 40. The control unit 40 transmits a control signal to the dehumidification / intrusion lamp 262 of the display lamp 249 so that the dehumidification / intrusion lamp 262 is turned on. Further, the control unit 40 transmits a control signal to the refrigeration cycle drive circuit 255 to drive the refrigeration cycle including the evaporator 211 and the condenser 212, and transmits a control signal to the fan motor drive circuit 251 so that the blower for cold air 214 and the warm air blower 215 are driven. In this way, a dehumidified air cleaning operation is performed in which air is cleaned together with dehumidification. On the other hand, when the dehumidification / off button 261 is pressed during the dehumidification / air cleaning operation, that is, when the dehumidification lamp 262 is lit, the control unit 40 transmits a control signal to the dehumidification lamp 262 to turn it off, Further, a control signal is transmitted to the refrigeration cycle driving circuit 255 to control the driving of the refrigeration cycle to be stopped. In this way, the air cleaning operation without dehumidification is performed.

  In step S206, the control unit 40 initially determines whether or not the dehumidification mode is “ON”. If the initial dehumidification mode is “ON”, the process proceeds to step S207, the dehumidification mode is set to “OFF”, and the dehumidification input lamp 262 is turned off. If the initial dehumidification mode is not “ON”, that is, if the initial dehumidification mode is “OFF”, the process proceeds to step S208, and the damper motor drive circuit 50 and the fan motor drive circuit are set so as to set the dehumidification mode to “ON”. The dehumidification lamp 262 is turned on by controlling the 251 and the refrigeration cycle driving circuit 255. Thereafter, the process proceeds to step S209. If the dehumidification on / off button is not pressed in step S205, the dehumidification mode remains at the initial setting.

  In step S209, the control unit 40 determines whether or not the off timer button 65 is “ON”. If the off timer button 65 is set to “ON”, the process proceeds to step S210. If the off timer button is not “ON”, the process proceeds to step S219.

  In step S210, the control unit 40 determines whether or not the off timer button 65 has been operated. If the off timer button 65 is operated, the process proceeds to step S213. If the off timer button 65 is not operated, the process proceeds to step S211.

  In step S214, the control unit 40 transmits a control signal to the time measuring unit 53, and sets the off timer time to 4 hours. Thereafter, the process proceeds to step S215, and the 4-hour lamp of the off timer lamp 66 is turned on, and then the process proceeds to step S220 in FIG.

  In step S216, the control unit 40 determines whether or not the off timer button 65 has been operated. If the off timer button 65 is operated, the process proceeds to step S219. If the off timer button 65 is not operated, the process proceeds to step S217.

  In step S217, the control unit 40 transmits a control signal to the time measuring unit 53, and sets the off timer time to 8 hours. Thereafter, the process proceeds to step S218, and the 8-hour lamp of the off timer lamp 66 is turned on, and then the process proceeds to step S220 in FIG.

  In step S219, the off timer is canceled and all off timer lamps 66 are extinguished. Thereafter, the process proceeds to step S220 in FIG.

  As shown in FIG. 18, in step S220, the control unit 40 determines whether or not the operation on / off button 60 has been pressed to “off”. If the operation on / off button 60 is set to “OFF”, the process proceeds to step S221. If the operation on / off button 60 is not set to “OFF”, the process returns to step S205 in FIG.

  In step S221, the control unit 40 determines whether or not the off timer is cancelled. If the off timer is released, the process proceeds to step S229. If the off timer is not released, the process proceeds to step S222.

  In step S222, the control unit 40 transmits a control signal to the time measuring unit 53 to start measuring time.

  In step S223, the control unit 40 determines whether or not the time measured by the time measuring unit 53 has passed the cut-off timer time based on the signal received from the time measuring unit 53. If the time measured by the time measuring unit 53 has passed the cut-off timer time, the process proceeds to step S224. If the time measured by the time measuring unit 53 has not expired, the process returns to step S205 in FIG.

  In step S224, the control unit 40 determines whether or not the off timer changeover switch 69 is operated and is set to “all stop”. If the off timer selector switch 69 is not set to “all stop”, the process proceeds to step S225. If the off timer selector switch 69 is set to “all stop”, the process proceeds to step S228.

  In step S225, the control unit 40 controls to release the off timer operation. In step S226, the control unit 40 controls the damper motor drive circuit 50, the fan motor drive circuit 251, and the refrigeration cycle drive circuit 255 so that the dehumidification is set to the “off” mode. In step S227, the ion generator drive circuit 52 is controlled so as to increase the amount of ions. Thereafter, the process returns to step S205 in FIG.

  By doing in this way, only after dehumidification timer time passes, only dehumidification operation can be stopped and air cleaning operation can be performed continuously. The amount of ions generated from the ion generator 17 increases with the elapse of the off timer time. In order to increase the amount of ions, the output voltage of the ion generator drive circuit 52 is increased, or the output pulse of the ion drive circuit is increased.

  The reason why the amount of ions is increased by these methods is that the energy given to the discharge electrode is increased. Alternatively, the rotation speed of the fan motor 9 is increased in order to increase the amount of air passing through the ion generator 17. This is because the amount of ions generated in the immediate vicinity of the discharge electrode is very large, so the amount of ions delivered to the space substantially increases just by increasing the amount of blown air, and the amount of generated ions itself increases. This is because it has an effect.

  On the other hand, in step S228, the control unit 40 cancels the off timer operation. In step S229, the damper motor driving circuit 50, the fan motor driving circuit 51, and the ion generator driving circuit 52 are controlled so that the dehumidifying function and the air cleaning function are stopped as in the conventional air purifier. Thereafter, the process returns to step S203 in FIG.

  In this embodiment, the slide switch is used as the switch-off timer changeover switch. However, the conventional operation of the button existing in the operation unit (long press, multiple simultaneous presses) causes the conventional switch after the switch-off timer time has elapsed. It may be switched whether the air purifying function is stopped as in an air purifier.

  As shown in FIG. 19, the operation process of the air purifier 200 may proceed to step S <b> 230 after step S <b> 227 shown in FIG. 18.

  In step S230, the control unit 40 sets the air volume to “weak” and controls the fan motor drive circuit 251 to rotate the cool air blower 214 and the hot air blower 215 at the lowest speed and the lowest output. Thereafter, the process returns to step S205 in FIG. The other steps of the flowchart of FIG. 19 are the same as the steps of the flowchart shown in FIG.

  In this embodiment, a slide switch is used as the switch-off timer changeover switch 69. However, a conventional operation of a button (long press, multiple simultaneous presses) on the operation unit causes the conventional switch to operate after the switch-off timer time has elapsed. It may be switched whether the air purifying function is stopped as in the case of the air purifier.

  As described above, the air purifier 200 according to the second embodiment includes the air purifying unit, the humidity adjusting unit, the control unit 40, the operation on / off button 60, the time measuring unit 53, and the off timer button 65. Prepare.

  The air purifier cleans the air. The humidity adjusting unit dehumidifies the air. The control unit 40 controls driving of the air cleaning unit and the humidity adjusting unit. The operation on / off button 60 is an operation on / off button 60 for the user to select to stop the operation of the air purifier 200. The timer 53 starts measuring time when the user selects to stop the operation of the air purifier 200 by the operation on / off button 60. A user inputs a timer time to be measured by the timer 53 to the off timer button 65.

  When the time measured by the time measuring unit 53 has passed the timer time, the control unit 40 stops driving the humidity adjustment unit and continues to drive the air purification unit and the humidity adjustment unit. To control.

  If the user wants to continue dehumidification by the air purifier 200 for a predetermined time after the user has selected to stop the operation of the air purifier 200 through the operation on / off button 60, the user can continue the predetermined time. The timer time is input to the off timer button 65 as follows.

  When the user inputs a timer time to the turn-off timer button 65 and selects to stop the operation of the air purifier 200 with the operation on / off button 60, the time measuring unit 53 starts measuring time. When the time measured by the time measuring unit 53 has passed the timer time, the control unit 40 stops driving the humidity adjusting unit. When the driving of the humidity adjusting unit is stopped, the dehumidification of air by the air purifier 200 is stopped. On the other hand, after the user selects that the operation of the air purifier 200 is stopped, the time measured by the time measuring unit 53 has passed the timer time, and the controller 40 dehumidifies the air. Even after being stopped, control is performed so that the air purifier is continuously driven.

  By doing in this way, the air cleaner 200 which can purify air even after completion | finish of a cut-off timer operation can be provided.

  In the air purifier 200 of the second embodiment, the air purifier includes an ion generator 217 that supplies ions into the air cleaning target chamber, a cool air blower 214, and a hot air blower 215. When the time measured by the time measuring unit 53 has passed the timer time, the control unit 40 causes the ion generator 217 and the cool air to continue to drive the ion generator 217, the cool air blower 214, and the warm air blower 215. The air blower 214 and the hot air blower 215 are controlled.

  By supplying ions into the air-cleaning target chamber by the ion generator 217, the cool air blower 214, and the hot air blower 215, deodorization and sterilization effects by the ions can be obtained. Therefore, when the time measured by the time measuring unit 53 has passed the timer time, the ion generator 217 and the cool air blower 214 are continuously driven so that the ion generator 217, the cool air blower 214, and the hot air blower 215 are continuously driven. By controlling the hot air blower 215, the air in the air-cleaning target chamber can be kept clean by the effect of the air cleaning by the ions even after the dehumidification of the air by the air cleaner 200 is stopped.

  Moreover, in the air cleaner 200 of 2nd Embodiment, when the time measured by the time measuring part 53 passes the timer time, the control part 40 is the ion generator 217, the air blower 214 for cold air, and the air blower for hot air. The ion generator 217, the cool air blower 214, and the hot air blower 215 are controlled so as to increase the amount of ions supplied into the air-cleaning target room by 215.

  When the humidity adjustment unit is a humidity adjustment unit that dehumidifies air, the air is dehumidified while the humidity adjustment unit is being driven. When the humidity adjustment unit is stopped, It is thought that humidity is the lowest.

  In such a state where the humidity in the air-cleaning target room is low, even if ions are supplied to the air-cleaning target room, effects such as sterilization, sterilization, and deodorization by ions can be sufficiently obtained as compared with a state where the humidity is high. There may not be.

  Therefore, when the time measured by the time measuring unit 53 has passed the timer time and the driving of the humidity adjusting unit is stopped, the ion generator 217, the cold air blower 214, and the hot air blower 215 are used to clean the air-cleaning target room. The ion generator 217, the cool air blower 214, and the hot air blower 215 are controlled so as to increase the amount of ions supplied to the air. By doing in this way, the effect of ions can be maintained similarly to the case where the humidity adjusting unit is driven regardless of the humidity in the air.

  Moreover, in the air cleaner 200 of 2nd Embodiment, the air purifying part contains the air blower 214 for cold air which sends out air, and the air blower 215 for hot air. When the time measured by the timer unit 53 has elapsed, the control unit 40 causes the cool air blower 214 and the hot air blower 215 to minimize the outputs of the cool air blower 214 and the hot air blower 215. To control.

  In the air cleaner 200, power consumed by the cold air blower 214 and the hot air blower 215 is often relatively large among the members. Therefore, when the time measured by the time measuring unit 53 has passed the timer time, the cool air blower 214 and the hot air blower 215 are controlled so that the outputs of the cool air blower 214 and the hot air blower 215 are minimized. To save power. On the other hand, even if the output of the cool air blower 214 and the warm air blower 215 is lowered to reduce the amount of air flow, the ion generator 217 and the cool air blower 214 are sufficiently supplied to the air cleaning target chamber. And the supply amount of ions by the hot air blower 215 are increased. By doing in this way, regardless of the humidity in the air, as in the case where the humidity adjusting unit is driven, it is possible to maintain the high effect of sterilization and deodorization by ions.

  Moreover, the air cleaner 200 of 2nd Embodiment is provided with the switch-off timer changeover switch 269 for a user to select the drive and drive stop of an air purifying part. When the user selects to stop the driving of the air purifier with the off timer changeover switch 269, the control unit 40 stops driving the air purifying unit when the time measured by the time measuring unit 53 has passed the timer time. To do.

  In this way, when it is not necessary to continue air cleaning after the timer time has elapsed, all operations are stopped in the same manner as conventional air purifiers to prevent energy waste. it can.

  In addition, although 1st Embodiment demonstrated the air cleaner 1 which has a humidification function, and 2nd Embodiment demonstrated the air cleaner 200 which has a dehumidification function, the air cleaner which has a function of both a humidification function and a dehumidification function is demonstrated. The same effect can be obtained for the machine. That is, in the air cleaner having both the humidifying function and the dehumidifying function, when performing the off timer operation during the humidifying operation, the operation is performed as in the first embodiment, and the dehumidifying operation is performed. When the off timer operation is performed during the operation, the operation as in the second embodiment is performed. The air cleaner may have other functions.

  The embodiment disclosed above should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above embodiments but by the scope of claims, and includes all modifications and variations within the meaning and scope equivalent to the scope of claims.
