Description

  The present invention relates to a floor-standing type air conditioner that can perform dehumidification by operation of a refrigeration cycle.

  In an air conditioner such as a dehumidifier in which a refrigeration cycle is housed in a housing, a clothes drying operation for drying clothes is performed by using a dehumidifying function to heat and blow dry air with a heating element.

In such a clothing drying operation, the dehumidifier described in Patent Document 1 generates negative ions to eliminate indoor odors. At this time, as the control of the ion generation amount, the amount of laundry dried in the room is selected, and when the amount of laundry is large, the generation amount of negative ions is increased. Alternatively, when the indoor humidity is high at the beginning of operation, the amount of negative ions generated is increased, and the amount of negative ions generated is decreased as the humidity decreases. Or the generation amount of a negative ion is reduced according to the elapsed time of clothing drying.
JP 2003-240265 A

  When performing clothes drying operation, when the laundry is dried and the operation is started immediately, the humidity in the room is not yet high. For this reason, when the ion generation amount is controlled in accordance with the humidity in the initial stage of operation, the humidity is low, so the ion generation amount remains small, and the ion effect cannot be sufficiently obtained. When the amount of ion generation is controlled according to the elapsed time of clothes drying, odorous components and airborne bacteria increase in the room as the laundry dries. However, since the amount of ion generation decreases, a sufficient ion effect cannot be obtained as well. In addition, when controlling the amount of ion generation according to the quantity of laundry, a user must select and there exists a possibility that the ion generation suitable for humidity and an odor may not be performed.

  Thus, there is a problem that the amount of ions generated is small when it is desired to sufficiently exhibit the effect of ions. Therefore, in view of the above, an object of the present invention is to provide an air conditioner such as a dehumidifier that can reliably exhibit the effect of ions when performing a clothes drying operation while generating ions.

  The present invention includes a housing in which a refrigeration cycle including an evaporator, a condenser, and a compressor, an ion generator that generates ions for sterilization, a drive circuit that drives the ion generator, and an evaporator. To blow out the dehumidified wind with ions from the air outlet, a humidity detector that detects the ambient humidity, and when the clothes are dried by the dehumidified wind, the amount of ions generated is changed according to the humidity. And a control device for controlling the drive circuit so that when the clothes drying operation is started, the control circuit controls the drive circuit so that the ion generation amount is larger than the normal ion generation amount regardless of humidity. It is.

  When the clothes drying operation is started, a large amount of ions are generated and blown out into the room from the outlet. As moisture evaporates from the clothes and dries, the humidity increases and mold fungi grow more easily. However, airborne fungi such as fungi floating in the room are removed by a large amount of ions, and the activity of fungi is suppressed. That is, when necessary, the sterilization effect by ions is maximized.

  And a control apparatus performs the control of the normal time which changes ion generation amount according to humidity, when fixed time passes since the clothing drying driving | operation start. After a certain period of time, the room is dehumidified and the humidity is lowered by the operation of the refrigeration cycle. Therefore, the growth of mold fungi is suppressed. At this time, since the number of ions may be smaller than that at the start of operation, a normal ion generation amount is obtained. However, normal control according to humidity is performed so that the amount of ion generation increases as the humidity increases. As described above, sterilization can be efficiently performed by controlling ion generation according to the situation.

  The cool mode that guides the warmed wind through the condenser to the other outlets, and the warmed air that passes through the condenser and the cooled air that passes through the evaporator are mixed into the outlet. The lead dry mode can be switched freely, and the dry mode is selected for the clothes drying operation.

  In the cool mode, the cooled air that has passed through the evaporator is blown out from the outlet, and the warmed air is blown out from the other outlet. In the dry mode, the cool air and the warm air are mixed, and a warm and dry air is blown out. Therefore, a dry mode is suitable for drying clothes, and clothes can be dried quickly. When clothes are not dried, cool air can be blown out in the cool mode.

  A heating element is provided on the downstream side of the evaporator, and the control device drives the heating element to warm the cold air when performing the clothes drying operation. As a result, a warm wind blows out. In particular, when the dry mode is selected, the wind is warmer. Therefore, drying of clothes is promoted and drying time can be shortened.

  According to the present invention, at the start of clothes drying operation, the amount of ion generation is controlled to be higher than usual regardless of the humidity in the room, and the amount of ion generation changes according to the humidity after a certain period of time. It is possible to generate as many ions as necessary at a certain time and to exert its effect reliably.

  In addition, during the clothes drying operation, a dry mode is selected in which the wind warmed through the condenser and the wind cooled through the evaporator are mixed and led to the outlet, and provided on the downstream side of the evaporator. Since the generated heating element is driven to warm the cold air, more air can be applied to the laundry and the hot air is blown out, so that the drying time can be shortened.

  The dehumidifier of this embodiment is shown in FIG. The synthetic resin housing 1 of the dehumidifier is of a vertically long type and has a structure with a small depth in the front-rear direction. In the housing 1, an evaporator 2, a condenser 3, and a compressor 4 are provided, respectively, and a refrigeration cycle is configured by these. The interior of the housing 1 is divided into upper and lower parts, an evaporator 2 and a condenser 3 are arranged on the upper side, and a compressor 4 is arranged on the lower side. A drain tank 5 is disposed below the evaporator 2. The drain tank 5 can be taken in and out from the lower part of the side surface of the housing 1.

  A first air outlet 6 is formed in the upper part of the front surface of the housing 1, a suction port 7 is formed in the center of the back surface, and a second air outlet 8 is formed above the first air outlet 6. An operation unit and a carrying handle are provided on the upper surface of the housing 1, and casters 9 are attached to the four corners of the lower surface so that the housing 1 can be easily moved.

  Inside the housing 1, there are a cold air passage 10 extending from the suction port 7 through the evaporator 2 to the first air outlet 6, and a hot air passage 11 extending from the air inlet 7 through the condenser 3 to the second air outlet 8. And are formed. In the cold air passage 10, a first blower 12 is disposed on the downstream side of the evaporator 2. The first blower 12 blows out the wind that has passed through the evaporator 2 from the first outlet 6. In the warm air path 11, the second blower 13 is disposed on the downstream side of the condenser 3. The second blower 13 blows out the wind that has cooled the condenser 3 from the second outlet 8.

  An ion generator 15 for generating positive ions and negative ions is provided in the cold air passage 10, and positive ions and negative ions are released into the room together with the cold air. The ion generator 15 is disposed on the downstream side of the first blower 12. A heater 16 is provided in the cold air passage 10 as a heating element. The heater 16 is disposed on the downstream side of the first blower 12 and warms the wind that has passed through the evaporator 2. The first blower outlet 6 is provided with a louver. The louver is turned up and down by a motor. A vertical louver is provided integrally with this louver. The vertical louver is rotated in the left-right direction by another motor.

  The hot air passage 11 is branched in the middle and connected to the cold air passage 10. The branch point is located on the downstream side of the second blower 13, and a damper 17 that switches the flow direction of the wind is provided at the branch point. By rotating the damper 17, the hot air passage 11 is switched between a state independent of the cold air passage 10 and a state connected to the cold air passage 10. Therefore, by the operation of switching air blowing, it is possible to select a flow of wind toward the second air outlet 8 and a flow of air toward the first air outlet 6 by mixing the warm air and the cold air. The rotation of the damper 17 is performed by lever operation. Alternatively, the damper 17 may be rotated by a motor. Moreover, you may switch ventilation by using a switching valve instead of the damper 17.

  And the control apparatus 20 which controls the driving | operation of a refrigerating cycle is provided. As shown in FIG. 2, the control device 20 composed of a microcomputer includes a humidity detector 21 that detects indoor humidity, a temperature detector 22 that detects room temperature, and an evaporator temperature detector that detects the temperature of the evaporator 2. 23, a heater temperature detector 24 for detecting the temperature in the vicinity of the heater 16, a full water detection device 25 for detecting the full water in the drain tank 5, and a vibration detector 26 for detecting vibration applied to the housing 1 are connected. Further, the motor drive circuit 27 for driving the motors of the blowers 12 and 13, the compressor drive circuit 28 for driving the compressor 4, the heater drive circuit 29 for energizing the heater 16, and the ion generator 15 A high voltage unit drive circuit 30 for applying a high voltage and a louver drive circuit 31 for driving a louver motor are connected to each other.

  The humidity detector 21 and the temperature detector 22 are arranged in the vicinity of the suction port 7 and detect the temperature and humidity of the air sucked from the room. The evaporator temperature detector 23 detects the surface temperature of the evaporator 2. The heater temperature detector 24 is disposed in the vicinity of the first outlet 6 on the downstream side of the heater 16. When the heater temperature detector 24 detects the temperature of the wind that has passed through the heater 16, the temperature in the vicinity of the heater 16 is indirectly detected.

  The full water detection device 25 includes a float 32 that moves up and down according to the water level of the drain tank 5, a magnet 33 provided integrally with the float 32, and a magnetic sensor 34 such as a Hall sensor that detects magnetism. The float 32 and the magnet 33 are disposed in the drain tank 5, and the magnet 33 is provided to face the float 32 with the support shaft interposed therebetween, and both move like a seesaw. The magnetic sensor 34 is provided above the drain tank 5 and is disposed so as to face the magnet 33. When the drain tank 5 becomes full, the magnet 33 moves away from the magnetic sensor 34, and the magnetic sensor 34 outputs an OFF signal, whereby full water is detected. Further, when the drain tank 5 is removed from the housing 1, the magnet 33 is separated from the magnetic sensor 34, and when the drain tank 5 is attached to the housing 1, the magnet 33 is close to the magnetic sensor 34. Thereby, the presence or absence of the drain tank 5 can be detected. That is, the full water detection device 25 also serves as a drain tank detector that detects the presence or absence of the drain tank 5.

  The vibration detector 26 is a general seismic instrument including a sphere and a switch that is turned on and off in accordance with the movement of the sphere. The vibration detector 26 is disposed in the upper part in the housing 1.

  And the control apparatus 20 drive-controls each drive circuit based on the information input from these detectors according to the selected operation mode. As the operation mode, cold air operation, clothing drying operation, clothing drying (quick drying) operation, automatic dehumidifying operation, continuous operation, and air blowing operation can be selected. The operation mode is selected by operating the operation switching button on the operation unit.

  In addition, a cool mode and a dry mode can be selected by an operation of switching air blowing. In the cool mode, the hot air passage 11 and the cold air passage 10 are independent of each other, cool air is blown out from the first air outlet 6, and hot air is blown out from the second air outlet 8. In the dry mode, the hot air passage 11 communicates with the cold air passage 10, and the cold air and the hot air are blown out simultaneously from the first air outlet 6, and the hot air is slightly blown out from the second air outlet 8. When the damper 17 is rotated by the motor, the cool mode or the dry mode can be automatically switched according to the operation mode.

  In cool air operation, select cool mode. Indoor air is sucked through the filter from the suction port 7 by the first blower 12. The wind flowing through the cold air passage 10 is cooled when passing through the evaporator 2 and becomes cold air. At this time, moisture condenses on the surface of the evaporator 2 and the cold air is dehumidified. The condensed moisture is collected in the drain tank 5. The cold air that has been dehumidified and dried is blown out from the first air outlet 6. In addition, indoor air is sucked through the filter from the suction port 7 by the second blower 13. The wind flowing through the warm air passage 11 is heated by the condenser 3 to become warm air and is blown out from the second outlet 8. At this time, each air blower 12 and 13 is driven according to the set air volume.

  In the clothes drying operation, the dry mode is selected. The indoor air sucked from the suction port 7 passes through the evaporator 2 and becomes dehumidified cold air. The wind warmed by the condenser 3 flows from the hot air passage 11 to the cold air passage 10. The dry cold air and the warm air are mixed and blown out from the first air outlet 6. At this time, each air blower 12 and 13 is driven according to the set air volume.

  In the clothes drying (fast drying) operation, the dry mode is selected and the heater 16 is operated. The flow of wind is the same as during clothes drying operation. Due to the operation of the heater 16, the cold air is warmed and mixed with the hot air, and the air having a higher temperature is blown out from the first air outlet 6. At this time, each air blower 12 and 13 is driven according to the set air volume.

  When the clothes drying (fast drying) operation is performed, the heater 16 is driven in conjunction with the compressor 4. When starting the clothes drying (quick drying) operation, the control device 20 turns on the heater 16 after the compressor 4 is turned on. When the clothes drying (quick drying) operation is finished, the compressor 4 is turned off after the heater 16 is turned off. That is, the heater 16 can be turned on only when the compressor 4 is turned on. Therefore, since the heater 16 is not driven independently, overheating can be prevented. For example, it is possible to prevent the temperature around the heater 16 from becoming high and damaging the housing 1. Further, it is possible to prevent high-temperature wind from blowing out.

  In automatic dehumidifying operation, the dry mode is selected. The flow of wind is the same as during clothes drying operation. At this time, each air blower 12 and 13 is driven according to the set air volume. Further, the operation of the refrigeration cycle is controlled according to the room temperature and the indoor humidity, and the dehumidifying operation and the air blowing operation are switched. That is, when the humidity is equal to or higher than the specified value, the dehumidifying operation is performed. When the humidity is less than the specified value, the operation of the refrigeration cycle is stopped and the air blowing operation is performed. The specified value varies depending on the room temperature. When the room temperature is lower than the standard temperature, the specified value is set to the standard humidity. When the room temperature is higher than the standard temperature, the specified value is set to a humidity lower than the standard humidity, for example, 55%. . The standard temperature is 27 ° C. or 28 ° C. The standard humidity is 60%.

  In the automatic dehumidifying operation, when the room temperature is lower than the standard temperature, the fans 12 and 13 are driven so that the air volume increases. That is, when the temperature becomes low, for example, 15 ° C. or lower, the air volume automatically increases. Thereby, the dehumidification capability at the time of low temperature increases.

  In continuous operation, select either cool mode or dry mode. Continuous dehumidification operation is performed regardless of humidity. At this time, each air blower 12 and 13 is driven according to the set air volume.

  In the air blowing operation, either the cool mode or the dry mode is selected. The refrigeration cycle is not operated, and only the fans 12 and 13 are driven.

  The control device 20 drives the ion generator 15 to generate positive ions and negative ions, and performs an ion operation for releasing them into the room. The ion operation is arbitrarily performed for each of the above operations. That is, the ion operation is performed when the ion operation button is operated.

  The ion generating device 15 includes an ion generating element and a high voltage unit driving circuit 30 that drives a high voltage unit that applies a high voltage thereto. When the control device 20 drives the high-voltage unit drive circuit 30, a high voltage is applied to the ion generating element, and positive ions and negative ions are generated from the ion generating element. Positive ions and negative ions are blown out from the first outlet 6 by the cold air flowing through the cold air passage 10.

  The control device 20 controls the ion operation according to the selected operation mode and adjusts the ion generation amount. As shown in FIG. 3, when ion operation is performed during clothes drying operation or clothes drying (fast drying) operation, high concentration operation is performed for a certain period of time, for example, 15 minutes regardless of humidity. When a certain time has elapsed, normal control for controlling ion operation according to humidity is performed. Normally, when the humidity is less than a second specified value higher than the specified value, for example, less than 70%, a standard operation is performed in which the amount of ions generated is smaller than that during high concentration operation. When the humidity is equal to or higher than the second specified value, for example, 70% or higher, a medium operation is performed in which the amount of ion generation is larger than that in standard operation and the amount of ion generation is smaller than in high concentration operation.

  When the ion operation is performed during the automatic dehumidification operation, the ion operation is controlled according to the humidity. The medium operation is performed when the humidity is equal to or higher than the second specified value. When the humidity is less than the second specified value, standard operation is performed. When ion operation is performed during continuous operation, standard operation is performed. Moreover, when performing ion operation at the time of cold wind operation or ventilation operation, standard operation is performed.

  The control device 20 controls the phase of the high voltage unit drive circuit 30. The high voltage unit drive circuit 30 outputs the drive signal shown in FIG. 4 to the high voltage unit. The high voltage unit applies a high voltage pulse voltage to the ion generating element according to the drive output of the high voltage unit drive circuit 30. The number of discharges in the ion generating element changes, and the amount of ion generation increases or decreases.

  As shown in FIG. 4, in the high concentration operation, the drive output of the high voltage unit drive circuit 30 is a pulse signal for one clock out of four clocks, and the number of discharges is about 150 times / second. The ion generation amount at this time is about 400,000 to 500,000 positive ions and negative ions / cc. In the middle operation, the drive output is a pulse signal once per clock, and the number of discharges is about 60 times / second. The amount of ions generated at this time is about 200,000 positive ions and negative ions / cc. In standard operation, the drive output is a pulse signal once every two clocks, and the number of discharges is about 30 times / second. The amount of ions generated at this time is about 150,000 positive ions and negative ions / cc.

  In the clothes drying operation or clothes drying (rapid drying) operation, the ion generator 15 is operated at a high concentration as the operation starts, and a large amount of positive ions and negative ions are released into the room. Even if the humidity is low at the start of operation, mold fungi are likely to propagate if the indoor humidity increases as the laundry dries. Since a large amount of ions can be released at a time when such sterilization is necessary, it is possible to remove floating bacteria such as mold bacteria, and to suppress the mold odor when mold is propagated. When the time elapses, the humidity is reduced by the dehumidifying function, so that the sterilization effect by ions can be sufficiently exhibited even when switching from the high concentration operation to the middle operation or the standard operation.

  Further, in the operation of the refrigeration cycle, the control device 20 controls the driving of the compressor 4 according to the room temperature. When the room temperature becomes less than the first temperature, for example, less than about 5 ° C., the compressor 4 is stopped to prevent the dehumidified water from freezing. When the room temperature is equal to or higher than the second temperature, for example, approximately 40 ° C. or higher, the operation of the refrigeration cycle is stopped, and the apparatus is protected without causing excessive force on the apparatus. When the room temperature is equal to or higher than the third temperature, for example, about 35 ° C. or higher, the fans 12 and 13 are rotated at a high speed while the compressor 4 is driven, so that the temperature of the compressor 4 is lowered.

  Furthermore, the control device 20 also performs a defrosting operation when detecting frost formation on the evaporator 2. As detection of frost formation, it is judged as frost formation when a predetermined frosted condition is satisfied. For example, when the room temperature becomes lower than a set temperature, for example, 19 ° C. or lower, or when the surface temperature of the evaporator 2 becomes lower than a predetermined temperature, for example, 0 ° C. or lower. The control device 20 performs the defrosting operation when detecting that the condition is satisfied by the output from the temperature detector 22 or the evaporator temperature detector 23.

  When the defrosting operation is started, the control device 20 stops the compressor 4 and drives the fans 12 and 13. A motor drive circuit 27 is provided for each of the fans 12 and 13, and each of the fans 12 and 13 is driven independently. The rotation speeds of the blowers 12 and 13 are increased so that the air volume is higher than the air volume set during the dehumidifying operation. By this defrosting operation, the indoor air sucked from the suction port 7 passes through the evaporator 2 and the frost attached to the evaporator 2 is melted. The air that has passed through the evaporator 2 is blown out from the first outlet 6. At this time, the louver is rotated upward. When the wind blows upward from the first air outlet 6, the warm wind does not directly hit the user, and the user does not feel uncomfortable.

  During the operation of the refrigeration cycle, the indoor air is dehumidified and water is accumulated in the drain tank 5. When the water level of the drain tank 5 becomes a constant water level, the control device 20 detects full water based on an output signal from the full water detection device 25. That is, when the float 32 rises as the water level rises, the magnet 33 falls. When the water is full, the magnetic sensor 34 cannot detect the magnetism of the magnet 33, and the magnetic sensor 34 outputs an off signal.

  When detecting that the water is full, the control device 20 stops the operation of the refrigeration cycle and performs a full water stop for stopping the driving of the blowers 12 and 13. After the drain tank 5 is taken out from the housing 1, when the drain tank 5 that has been emptied is attached, the magnetic sensor 34 of the full water detection device 25 detects the magnetism of the magnet 33 in the drain tank 5. When the magnetic sensor 34 outputs an ON signal, the control device 20 detects that the drain tank 5 is attached and enters an operation standby state. In addition, when the drain tank 5 after drainage is mounted, control may be performed so that the operation before the full water stop is automatically resumed.

  Further, when vibration is applied to the housing 1 or the housing 1 falls, the vibration detector 26 detects this movement and outputs an ON signal. The control device 20 determines the degree of vibration based on the output of the vibration detector 26. In the case of slight vibrations, the output from the vibration detector 26 is an instantaneous on signal or a short on signal. On the other hand, in the case of strong vibration or falling, the output from the vibration detector 26 is a continuous on signal or a long on signal. When the ON signal is input when the predetermined time has elapsed, the control device 20 determines that the vibration is abnormal. When the ON signal is not input when the predetermined time has elapsed, the control device 20 has a slight vibration. Judge that it is not abnormal. In this way, a time lag of a predetermined time is provided from when the vibration is first detected until the control is started. This time lag time is a time from the time when the ON signal from the vibration detector 26 is input to the time when the determination is made.

  And when it is judged that it is abnormal vibration, the control apparatus 20 stops all the driving | operations immediately, and performs the abnormal stop which turns off a power supply. At this time, the control device 20 also stops operating. To recover from an abnormal stop, a special operation such as operating the operation button twice is required. When the special operation is performed, the power is turned on, the control device 20 is started, and the operation is controlled.

  When the operation is started immediately after the abnormal stop, the vibration detector 26 may shake and output an ON signal. In this case, when a special operation is performed, the control device 20 does not accept an input from the vibration detector 26 for a certain period of time. Even if the vibration detector 26 outputs an ON signal during a certain time, the control device 20 ignores this signal and does not perform an abnormal stop. When a certain time has elapsed, the operation is started. Therefore, the abnormal stop is not repeated and the operation can be started immediately.

  By the way, when the drain tank 5 becomes full, the drain tank 5 is taken out from the housing 1 and drained. The drain tank 5 that has been emptied is mounted on the housing 1. At the time of this attachment / detachment, an impact is applied to the housing 1 and the housing 1 is shaken. The vibration detector 26 detects this vibration.

  Therefore, when the control device 20 detects that the drain tank 5 is full, control by detecting vibration is prohibited. That is, since the drain tank 5 is attached and detached when the drain tank 5 is full, the control device 20 does not perform an abnormal stop even if it detects vibration.

  Thus, when the drain tank 5 is full, the drain tank 5 is attached and detached. At this time, vibration is applied to the housing 1 and the vibration detector 26 detects the vibration. However, this vibration is ignored and an abnormal stop is avoided. Therefore, it is not necessary to perform a special operation each time the drain tank 5 is attached / detached to restore the operation, and convenience can be improved.

  Moreover, after taking out the drain tank 5 which became full, the empty drain tank 5 is mounted | worn. Also at this time, the housing 1 vibrates, and the control device 20 may determine that the vibration is abnormal. Therefore, the control device 20 prohibits the control by detecting the vibration for a predetermined time when the water level in the drain tank 5 is detected and then a water level lower than a certain level is detected. That is, when the drain tank 5 is mounted during a full water stop, the control device 20 does not perform an abnormal stop even if vibration is detected.

  In this way, when the drain tank 5 that has been emptied is mounted, vibration is applied to the housing 1 and the vibration detector 26 detects vibration. However, this vibration is ignored only for a predetermined time, and an abnormal stop is avoided. This predetermined time is set to a time within which vibrations generated when the drain tank 5 is attached are not detected. Therefore, unnecessary abnormal stops can be eliminated, and convenience can be improved.

  In addition, when the dehumidifying operation of cold air driving, clothing drying operation, clothing drying (quick drying) operation, automatic dehumidifying operation, or continuous operation is stopped by operating the operation button, the control device 20 performs the re-operation. The drive of the compressor 4 is regulated. That is, after the dehumidifying operation is stopped, when the operation button is operated for re-operation, the compressor 4 is not driven for a certain time, for example, 3 minutes, and only the blowers 12 and 13 are driven. When a certain time elapses, the compressor 4 is driven and the operation of the refrigeration cycle is started. The same control is performed when the operation button is operated immediately after the power plug is inserted. As a result, the compressor 4 is not loaded, and the apparatus can be protected.

  In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added to the said embodiment within the scope of the present invention. In addition to the dehumidifier, the air conditioner may be a floor-mounted type that is movable, and examples include an integrated air conditioner, a cooler, and a cool air cooler. The operation of the refrigeration cycle that drives the heater is not limited to clothes drying (quick drying) operation, and the temperature of the blown air is adjusted by driving the heater during clothes drying operation, automatic dehumidification operation, and automatic operation.
