It was. Therefore, there has been a problem that the humidification operation is not resumed and the humidity cannot be controlled.

  Also, in order to control the humidity to the set humidity with the control of the conventional air conditioner, switching between dehumidifying operation and humidifying operation according to the humidity, it is uncomfortable to humidify in the summer with a prejudice image, It was very uncomfortable.

  Furthermore, the dehumidified liquid is unsanitary because it is a liquid containing dust and dust outside the main body. Performing a humidifying operation using the liquid is very unsanitary because it causes dust and dust to be released along with humidification outside the main body.

  Therefore, in view of the above problems, an object of the present invention is to provide an air conditioner having a control for reducing the frequency of switching to a humidifying operation while controlling the humidity to a set humidity.

  The air conditioner according to the invention of claim 1 is an air conditioner including a control unit that switches between a dehumidifying operation and a humidifying operation based on a humidity detected by the detecting unit, and includes a dehumidifying tank and a humidifying tank separately, The control means performs the dehumidifying operation when the detected humidity rises above a set humidity, and performs the humidifying operation when the detected humidity falls below a predetermined humidity lower than the set humidity. To do.

It is a block diagram which shows the structure of the air conditioner in one Example of this invention. It is a perspective view of an air conditioner same as the above. FIG. 3 is a perspective view showing a state in which the front panel member is removed in FIG. It is a chart figure which shows the operation control of an air conditioner accompanying a change of humidity same as the above.

  Hereinafter, preferred embodiments of an air conditioner according to the present invention will be described with reference to the accompanying drawings.

  1 to 4 show an embodiment of an air conditioner of the present invention. FIG. 1 shows a schematic configuration of the air conditioner. The control means 1 provided in the air conditioner is specifically composed of a microcomputer, for example, and performs a series of operations in accordance with a program control sequence stored in a storage means (not shown) of the microcomputer. It is configured. On the input side of the control means 1 are a temperature detection means 2 for detecting the temperature inside the room around the air conditioner, a humidity detection means 3 for detecting the humidity around the air conditioner, operation buttons, operation switches, a touch panel, etc. And operating means 4 comprising: Further, on the output side of the control means 1, a dehumidifying means 5 for performing dehumidifying operation for sending dry air from the air conditioner to the outside, and a humidifying means 6 for performing humidifying operation for sending humid air from the air conditioner to the outside. And an air blowing means 7 such as an air blowing fan that performs an air blowing operation for sending air from the air conditioner to the outside. Further, the control means 1 automatically performs on / off control of the dehumidifying means 5, the humidifying means 6 and the blowing means 7 based on the detection signals from the temperature detecting means 2 and the humidity detecting means 3 according to the control sequence of the program. An operation switching means 8 that automatically switches the operation to the dehumidifying operation, the humidifying operation, and the air blowing operation is provided.

  FIG. 2 shows the appearance of the air conditioner, and FIG. 3 shows a state where the front panel of the air conditioner is removed. A main body 9 formed in a hollow box shape indicated by reference numeral 9 includes the operation means 4 and a front panel member 10 in which a front surface portion of the main body 9 is detachably formed, and is provided in the dehumidifying means 5. A dehumidifying tank 11 and a humidifying tank 12 of the humidifying means 6 are detachably provided on the main body 9 independently of each other.

  Here, the dehumidifying means 5 in the present embodiment may be configured to store the condensed water collected inside the air conditioner after dehumidification in the dehumidifying tank 11, and the dehumidifying method is also a compressor using a compressor as a compressor. It is applicable to a formula (refrigeration cycle type), a desiccant type (zeolite type, silica gel type), a hybrid type combining a compressor type and a desiccant type, and the like.

  Further, the humidifying means 6 in this embodiment may be configured to receive water from the humidifying tank 12, and the humidifying system is a steam fan type in which water is boiled by electric heat from a heater or the like and the steam is discharged by the blowing means. It can be applied to an ultrasonic type that discharges humidified air into fine particles by ultrasonic waves, or a vaporized type that discharges humidified air by passing air through a filter or nonwoven fabric containing water by the blower 7. is there.

  Next, the operation of the air conditioner having the above configuration will be described. First, the air conditioner is turned on (not shown), and the operation means 4 is operated to perform various settings such as setting determination of the set humidity H1 and various operations such as start of operation.

  Based on the set humidity H1, the operation switching means 8 performs automatic operation switching control for automatically switching between the dehumidifying operation, the humidifying operation, and the air blowing operation. As shown in FIG. 4, for example, when the set humidity H1 is 50% and the indoor humidity detected by the humidity detecting means 3 at the start of the operation of the air conditioner is 60%, the dehumidifying operation is selected by the operation switching means 8. Is done. Thereafter, when the humidity in the room decreases due to the dehumidifying operation and reaches 49% (dehumidifying operation / fan operation switching set humidity H2) which is lower than 50% of the set humidity, the operation switching means 8 is not shifted to the humidifying operation. Thus, the dehumidifying means 5 is stopped and the operation is switched to the blowing operation in which only the blowing means 7 is operated. Here, if the dehumidifying operation is not performed in a state where the outside air is hot and humid as in summer, the indoor humidity increases. If the blowing operation is continued, the indoor humidity naturally increases. Then, after the air blowing operation is continued and the indoor humidity rises, the indoor humidity reaches around 55%, which is the air blowing operation / dehumidifying operation switching setting humidity H3, and then again from the air blowing operation to the dehumidifying operation by the operation switching means 8. If the dehumidifying operation is started, the indoor humidity can be controlled near the set humidity H1 without performing the humidifying operation.

  Further, when the indoor humidity is controlled by the automatic operation switching control by the operation switching means 8 and the air blowing operation is continued and the indoor humidity further decreases, the indoor humidity is set to the air blowing operation / humidification operation switching setting. When the humidity H4 drops to around 35%, if the operation switching means 8 switches from the blowing operation to the humidifying operation to start the humidifying operation, the dehumidifying operation and the humidifying operation are frequently switched around the set humidity H1. Therefore, the frequency of shifting to the humidifying operation can be reduced, and the burden of frequent water supply to the humidifying tank 12 in a humid summer can be reduced.

  Thus, the control means 1 performs the dehumidifying operation when the detected humidity rises from the set humidity H1 and reaches the blowing operation / dehumidifying operation switching set humidity H3 (H3> H1), and the detected humidity is reduced during the dehumidifying operation. When the dehumidifying operation / blower operation switching setting humidity H2 (H1> H2) lower than the set humidity H1 is reached, the operation is switched from the dehumidifying operation to the non-humidifying air blowing operation, and the detected humidity is the set humidity H1 and dehumidifying operation. The operation is switched from the air blowing operation to the humidifying operation when the air pressure is lower than the air blowing / humidifying operation switching setting humidity H4 (H1> H2> H4) as a predetermined humidity lower than the air blowing operation switching setting humidity H2.

  Further, since the body 9 is provided with the dehumidifying tank 11 and the humidifying tank 12 separately, the temperature and humidity in the room are read by the control means 1, and the dehumidifying operation, the humidifying operation and the air blowing operation by the operation switching means 8 are automatically switched. When performing the automatic operation switching control, the condensed water collected in the main body 9 during the dehumidifying operation is stored in the dehumidifying tank 11, and the water in the humidifying tank 12 is used for supplying water to the humidifying means 6 during the humidifying operation. The condensate collected by the dehumidifying operation is not used for the humidifying operation, and the dust and dirt floating in the indoor air that the condensed water has taken in during the dehumidifying operation is prevented from being released into the room during the humidifying operation. Can be humidified.

  As described above, in this embodiment, during the automatic operation, the dehumidifying operation is selected when the indoor humidity rises above the set humidity H1, and then the dehumidifying operation is performed, and the indoor humidity decreases below the set humidity H1. The dehumidifying operation / blower operation switching setting humidity H2 at the time is not immediately switched to the humidifying operation, and the operation is shifted to the humidifying operation at the air blowing / humidifying operation switching setting humidity H4 when the indoor humidity is significantly reduced. .

  In this case, by reducing the frequency of humidification operation and reducing the number of times of water supply to the humidification tank 12, the uncomfortable feeling of supplying water to the humidification tank 12 can be reduced as much as possible in high-temperature and high-humidity summertime where there is a prejudice image.

  In addition, this invention is not limited to the said Example, A various deformation | transformation implementation is possible. For example, the dehumidifying operation / blower operation switching setting humidity H2, the blowing operation / dehumidifying operation switching setting humidity H3, and the blowing operation / humidifying operation switching setting humidity H4 can be appropriately changed according to the set humidity H1, the room temperature, or the room humidity. It shall be Moreover, it is good also as a structure which provides alerting | reporting means, such as a buzzer, and alert | reports when the content volume of the water in the humidification tank 12 falls.
