Description

  The present invention relates to an air conditioner that can perform air conditioning of an air-conditioning target space by using a humidity control action of a humidity control rotor, and more specifically, a humidification type air conditioner that humidifies an air-conditioning target space, and an air-conditioning target space There is a dehumidification type air conditioner that performs dehumidification.

The humidification type air conditioner has the following configuration.
That is, an air supply / air blowing means that ventilates a supply air supply passage for supply air to be supplied to an air-conditioning target space, an exhaust air supply means that ventilates an exhaust air passage for discharge air discharged outside the air-conditioning target space, and a part Is arranged in the supply air passage and the other part is arranged in the exhaust air passage, and a portion of the humidity adjustment body located in the supply air passage and the exhaust air passage And a humidity control rotor provided with a driving means for driving and rotating the humidity control body so as to change the part positioned at the rotation, and at a location on the upper side of the ventilation direction than the humidity control body in the supply air path An air conditioning heating means is provided so as to heat the flowing air, the air conditioning heating means is brought into a heating action state, the supply air blowing means and the exhaust air blowing means are respectively operated, and the humidity control Rotates the body continuously The drive means is operated to supply the supply air to the air-conditioning target space in a state adjusted by the humidity control rotor, and the air in the air-conditioning target space is discharged as air by the ventilation action of the exhaust air blowing means. It is configured to discharge to the outside.

  Then, the supply air heated by the air conditioning heating means passes through the portion located in the air supply air passage in the humidity control body, and the exhaust air from the air conditioning target space is located in the exhaust air passage in the humidity control body. By operating in a form that passes through the part to be air-conditioned, water vapor in the air for discharge from the air-conditioning target space is absorbed by the humidity control body, and the moisture absorbed by the humidity control body is released to the supply air and supplied Since the working air is supplied to the air-conditioning target space in a humidified state, the air-conditioning target space can be humidified with no water supply. Therefore, the humidification operation can be performed as the air conditioning operation.

The dehumidifying type air conditioner has the following configuration.
That is, it is provided with an air supply air blowing means, an exhaust air blowing means, and a humidity control rotor similar to those described in the humidification type air conditioner, and is located on the upper side of the ventilation direction than the humidity control body in the exhaust air path The air-conditioning heating means is provided so as to heat the air flowing in the air-conditioner, the air-conditioning heating means is brought into a heating action state, the supply air blowing means and the exhaust air blowing means are respectively operated, and The driving means is operated so as to continuously drive and rotate the humidity control body, and the supply air is supplied to the air-conditioning target space in a state of humidity control by the humidity control rotor.

  And after the air for discharge from the air conditioning target space is heated by the air conditioning heating means, it passes through the portion located in the exhaust air passage in the humidity control body, and the supply air is in the air supply air passage in the humidity control body Since the water vapor in the supply air is absorbed by the humidity control body and supplied to the air-conditioning target space, it is possible to dehumidify the air-conditioning target space. Therefore, the dehumidifying operation can be performed as the air conditioning operation (see, for example, Patent Document 1).

  Although not described in Patent Document 1, in such an air conditioner, when it is not necessary to perform dehumidification or humidification, instead of performing the air conditioning operation as described above, the air in the ventilation target space is simply ventilated. There are also cases where normal ventilation operation is performed. In other words, the heating operation of the air conditioning heating unit is stopped, and the supply air blowing unit and the exhaust ventilation unit are operated in a state where the driving rotation of the humidity control body by the driving unit of the humidity control rotor is stopped. .

JP 2003-4255 A

  By the way, in the case where the room in the house is an air-conditioning target space, it may include a space where odors may be generated, such as a toilet or bathroom, and the outside air is supplied in addition to the air in the house. Even in such a case, the outside air supplied may contain odors. However, these odor components include, for example, water-soluble odors such as ammonia and formaldehyde. Ingredients may be included.

  In the air conditioner, the humidity control is performed when the normal ventilation operation is performed or when the operation of the air conditioning heating unit, the humidity control rotor, the supply air blowing unit, and the exhaust ventilation unit is stopped. When the air containing the odorous component as described above passes through the humidity control body in a state where the driving rotation of the humidity control body by the rotor driving means is stopped, the odorous component contained in the air is transferred to the humidity control body. There is a risk of adhesion.

  That is, when the air containing the water-soluble odor component passes through the humidity control body in the state where the driving rotation of the humidity control body is stopped as described above, the odor component contained in the air adheres to the humidity control body. Or, it may dissolve in moisture absorbed by the humidity control body, and odorous components may accumulate in the humidity control body.

  And conventionally, the dehumidifying operation and the humidifying operation are started after the state in which the normal ventilation operation is performed or the state where the operation of all devices is stopped and the operation is stopped for a long time. At that time, the operation is performed with the odorous component adhering and accumulating on the humidity control body, so that a part of the odorous component accumulated in the humidity control body is mixed into the supply air and returned to the air conditioning target space. There is a fear that there is a disadvantage that the comfort when dehumidifying and humidifying the air-conditioned space is reduced. In particular, if the accumulated amount of odorous components with respect to the humidity control body is increased, the amount of odorous components mixed into the supply air and returning to the air-conditioning target space will increase, making it impossible to comfortably air-condition the air-conditioning target space. There was a problem.

  By the way, in the configuration for performing the dehumidifying operation as described above, the exhaust air from the air-conditioning target space is heated by the air-conditioning heating means, and then passes through the portion located in the exhaust air passage in the humidity control body. Since it is discharged outside, the moisture contained in the humidity control body evaporates, so some of the odor components dissolved in the moisture are removed and discharged to the outside, but in this dehumidifying operation, Since the dehumidifying operation is performed while the humidity control rotor rotates continuously, the portion located in the exhaust air passage in the humidity control body is continuously replaced with the portion located in the air supply path. Rotate and move toward the portion located in the air supply path without sufficiently removing the odorous component. Therefore, since the odor component supplied to the air-conditioning target space remains, the air-conditioning target space may not be comfortably air-conditioned.

  An object of the present invention is to provide an air conditioner capable of removing such odorous components even if the odorous components adhere to the humidity control body.

An air conditioner according to the present invention includes an air supply air blowing means that ventilates an air supply air passage for supply air to be supplied to an air conditioning target space,
Exhaust air blowing means that ventilates the exhaust air path of the discharge air that is discharged outside the air conditioning target space;
A humidity control body arranged so that a part is located in the air supply air passage and another part is located in the exhaust air air passage, and a portion of the humidity control body located in the air supply air passage and the exhaust A humidity control rotor provided with a drive means for driving and rotating the humidity control body so as to change the part positioned in the air passage with rotation;
Heating means for air conditioning that heats the air that flows at a location closer to the ventilation direction than the humidity control body in the air supply air path;
An operation control means for controlling the operation,
The operation control means is
With the air conditioning heating means in a heating action state, the air supply and air exhaust means and the exhaust air blowing means are respectively operated, and the driving means is operated so as to continuously drive and rotate the humidity control body, It is configured to execute an air-conditioning operation for supplying the supply air to the air-conditioning target space in a state in which the humidity is adjusted by the humidity-control rotor,
The first characteristic configuration is provided with a deodorizing heating means that heats the air that flows in a location closer to the ventilation direction than the humidity control body in the exhaust air passage,
The operation control means is
The deodorizing heating means is brought into a heating action state, and at least the exhaust air blowing means of the supply air blowing means and the exhaust air blowing means is operated, and the humidity control is performed only while the set time for drying elapses. A process of stopping the rotation of the body and a process of rotating the humidity control body by a set angle in a form in which a part of the part positioned in the exhaust air passage in the humidity control body is replaced with another part are repeatedly executed. Thus, the drive means is operated so as to perform a deodorizing operation in which the moisture absorbed in the humidity control body is released to the exhaust air and removed.

  According to the first characteristic configuration, when the operation control means executes the deodorizing operation, the heating means for deodorization is brought into a heating action state, and at least the air blowing means and the exhaust air blowing means are Since the exhaust air blowing unit is operated, the exhaust air from the air-conditioning target space is operated in a form that passes through a portion of the humidity control body located in the exhaust air passage while being heated by the deodorizing heating unit. Thus, the moisture absorbed by the humidity control body is released to the exhaust air passing through the humidity control body, so that the odor component dissolved in the moisture absorbed by the humidity control body At the same time, the odor component that is removed while being released to the discharge air and adhered to the humidity control body is removed while being released to the discharge air or dissolved in the water vapor in the discharge air.

  In the deodorizing operation, the operation control means is one of a process for stopping the rotation of the humidity control body only during the set time for drying and a portion of the humidity control body that is positioned in the exhaust air passage. Since the driving means is operated so as to repeatedly execute the process of rotating the humidity control body by a set angle in a form in which the part is replaced with another part, the driving means is positioned in the exhaust air passage by driving rotation of the driving means. In all the regions of the humidity control body, the attached odorous component can be surely removed.

  In other words, since the rotation of the humidity control body is stopped only for the set time, the air heated by the deodorizing heating means is adjusted in such a state that the rotation of the humidity control body is stopped. Since it is supplied to the portion of the wet body that is positioned in the exhaust air passage, air continues to be supplied in a state where the rotation is stopped in the portion that is located in the exhaust air passage. It will be removed by evaporation. Along with that, the odorous component dissolved in the water is accurately removed.

  In addition, such a process of stopping the rotation of the humidity control body and a process of rotating the humidity control body by a set angle in a form in which a part of the part positioned in the exhaust air passage in the humidity control body is replaced with another part. Is repeatedly performed, moisture and odor components can be accurately removed from all regions of the humidity control body.

  In other words, the humidity control rotor changes the part positioned in the supply air path and the part positioned in the exhaust air path with rotation, so that the humidity control body is rotatably supported. A partition body for dividing the air passage is provided at a portion of the frame where the air supply air passage and the exhaust air passage are partitioned.

  Then, when the humidity control body is rotated by a set angle, all of the portions positioned in the exhaust air passage are replaced with other portions, for example, the supply air passage and the exhaust air passage are halved. If the humidity control body is configured to rotate 180 °, the portion covered by the partition body in the humidity control body is again covered by the partition body even if it is rotated. Removal may not be possible.

  On the other hand, as described above, since the humidity control body is rotated in such a manner that a part of the portion positioned in the exhaust air passage is replaced with another part, the rotation of the humidity control body is stopped. The portion covered with the partition body can be positioned in the exhaust air passage, and the odor component can be accurately removed from the portion covered with the partition body.

  Incidentally, such a deodorizing operation is considered to be necessary to remove odorous components, for example, to be performed every time the operation time reaches the set time or to be performed every time the air conditioning operation is started. It will be executed appropriately at the timing.

  Therefore, according to the first characteristic configuration, in the air conditioner capable of performing the humidification operation as the air conditioning operation, even if the odor component adheres to the humidity control body, such odor component is removed. It was possible to provide an air conditioner that would be possible.

The second characteristic configuration of the present invention is a supply air blowing means for ventilating the supply air supply passage for the supply air supplied to the air-conditioning target space,
Exhaust air blowing means that ventilates the exhaust air path of the discharge air that is discharged outside the air conditioning target space;
A humidity control body arranged so that a part is located in the air supply air passage and another part is located in the exhaust air air passage, and a portion of the humidity control body located in the air supply air passage and the exhaust A humidity control rotor provided with a drive means for driving and rotating the humidity control body so as to change the part positioned in the air passage with rotation;
A heating means for air conditioning that heats the air that flows at a location closer to the ventilation direction than the humidity control body in the exhaust air path;
An operation control means for controlling the operation,
The operation control means is
With the air conditioning heating means in a heating action state, the air supply and air exhaust means and the exhaust air blowing means are respectively operated, and the driving means is operated so as to continuously drive and rotate the humidity control body, An air conditioner configured to perform an air conditioning operation for supplying the supply air to the air conditioning target space in a state of being conditioned by the humidity control rotor,
The operation control means is
The air conditioner heating means is brought into a heating action state to operate at least the exhaust air blowing means of the air supply air blowing means and the exhaust air blowing means, and the humidity control body only during a set time for drying. The process of stopping the rotation of the humidity control body and the process of rotating the humidity control body by a set angle in such a manner that a part of the part positioned in the exhaust air passage in the humidity control body is replaced with another part are repeatedly executed. As described above, the driving means is operated so as to perform a deodorizing operation in which the moisture absorbed in the humidity control body is released to the exhaust air and removed.

  According to the second characteristic configuration, when the operation control means performs the deodorizing operation, the heating means for air conditioning is brought into a heating action state, and at least the exhaust air among the supply air blowing means and the exhaust air blowing means. Since the air blowing means will be operated, the exhaust air from the air-conditioning target space is operated in a form that passes through the portion located in the exhaust air passage in the humidity control body while being heated by the air conditioning heating means, Since the moisture absorbed in the humidity control body is released to the discharge air passing through the humidity control body, the odor component dissolved in the moisture absorbed in the humidity control body is discharged together with the moisture. The odor component that is removed while being released into the air and adhered to the humidity control body is removed while being released into the discharge air or dissolved in the water vapor in the discharge air.

  In the deodorizing operation, the operation control means is one of a process for stopping the rotation of the humidity control body only during the set time for drying and a portion of the humidity control body that is positioned in the exhaust air passage. Since the driving means is operated so as to repeatedly execute the process of rotating the humidity control body by a set angle in a form in which the part is replaced with another part, the driving means is positioned in the exhaust air passage by driving rotation of the driving means. In all the regions of the humidity control body, the attached odorous component can be surely removed.

  In other words, since the rotation of the humidity control body is stopped only while the set time for drying elapses, the air heated by the deodorizing heating means in a state where the rotation of the humidity control body is stopped in this manner. Is supplied to a portion of the humidity control body that is positioned in the exhaust air passage, and air is continuously supplied in a portion that is positioned in the exhaust air passage in a state where the rotation is stopped. It will be properly evaporated and removed. Along with that, the odorous component dissolved in the water is accurately removed.

  In addition, such a process of stopping the rotation of the humidity control body and a process of rotating the humidity control body by a set angle in a form in which a part of the part positioned in the exhaust air passage in the humidity control body is replaced with another part. Is repeatedly performed, the odorous component can be accurately removed from all regions of the humidity control body.

  In other words, the humidity control rotor changes the part positioned in the supply air path and the part positioned in the exhaust air path with rotation, so that the supply air path, the exhaust air path, Since the partition body for partitioning the air path is provided at the place where the air is partitioned, for example, when the humidity control body is rotated by a set angle, all of the portions positioned in the exhaust air path are all For example, if the supply air passage and the exhaust air passage are provided in half, and the portion to be positioned in the exhaust air passage and the other portion are each formed in a semicircular shape, If the humidity control body is rotated 180 °, the portion covered by the partition body after being rotated is again covered by the partition body, and there is a possibility that the odor component cannot be removed. However, as described above, since the humidity control body is rotated in a form in which a part of the part positioned in the exhaust air passage is replaced with the other part, the location covered by the partition body, It will be able to remove odorous components accurately.

  Incidentally, it is necessary to remove such odor components, for example, such that the deodorizing operation is performed every time the operation time reaches a preset time or the air conditioning operation is started. It will be executed appropriately at the timing considered.

  Therefore, according to the second feature configuration, even in the case where the odorous component may adhere to the humidity control body in the air conditioner capable of performing the dehumidifying operation as the air conditioning operation, such odorous component is removed. It was possible to provide an air conditioner that would be possible.

  According to a third feature configuration of the present invention, in addition to the first feature configuration or the second feature configuration, the operation control means performs ventilation by the exhaust air blowing means in the deodorizing operation as compared to when the air conditioning operation is performed. It is in the point which is comprised so that quantity may be reduced.

  According to the third feature, since the amount of ventilation by the exhaust air blowing means is reduced in the deodorizing operation compared to when the air conditioning operation is performed, the deodorizing heating means or the air conditioning heating is performed. The temperature of the air heated by the means is less likely to be lowered, and since it is ventilated toward the humidity control body at a high temperature, it is easier to accurately remove the odor component by evaporating the moisture. Become.

  Therefore, according to the third characteristic configuration, it becomes easier to more accurately remove the odor component adhering to the humidity control body.

  According to a fourth feature configuration of the present invention, in addition to any one of the first feature configuration to the third feature configuration, the operation control unit stops the ventilation operation of the air supply and blowing unit in the deodorizing operation. It is in the point which is comprised.

  According to the fourth characteristic configuration, since the ventilation operation of the air supply / air blowing means is stopped in the deodorizing operation, moisture containing odor components evaporated by executing the deodorizing operation is erroneously supplied. It does not enter the air duct and be supplied toward the air-conditioning target space.

  Therefore, according to the fourth characteristic configuration, it is possible to remove the odor component adhering to the humidity control body without impairing the comfort of the air-conditioning target space during execution of the deodorizing operation.

  According to a fifth characteristic configuration of the present invention, in addition to any one of the first characteristic configuration to the fourth characteristic configuration, the operation control unit performs the deodorizing operation when the start of the air conditioning operation is instructed. When the start of the air conditioning operation is instructed, and when the previous set time for determination has not elapsed since the end of the previous execution of the deodorizing operation, There exists in the point comprised so that the said air conditioning operation may be performed, without performing the said deodorizing operation.

  According to the fifth characteristic configuration, when the start of the air conditioning operation is instructed, the deodorizing operation is executed prior to the air conditioning operation, so even if the odor component may adhere to the humidity control body, The air conditioning operation is executed after the odor component is removed from the humidity control body by the deodorizing operation, and the odor component is mixed in the supply air supplied to the air conditioning target space when the air conditioning operation is executed. It is suppressed.

  Further, when the start of the air conditioning operation is instructed, if the set time for determination has not elapsed since the end of the previous execution of the deodorizing operation, the deodorizing operation is not performed. Since the air-conditioning operation is performed, the air-conditioning operation can be started immediately without a time delay in accordance with the start command in a state where there is little possibility of impairing the comfort of the air-conditioning.

  In other words, if the set time for determination has not elapsed since the previous execution of the deodorizing operation has been completed, the accumulated amount of odorous components with respect to the humidity control body is small, and the air conditioning operation is performed. It is considered that the supply air supplied to the air-conditioning target space has few odorous components mixed in when air conditioning is performed and there is little risk of impairing the comfort of air conditioning. Therefore, when the start of the air-conditioning operation is commanded, the air-conditioning operation is performed without executing the deodorizing operation unless the set time for determination has elapsed since the end of the previous execution of the deodorizing operation. By adopting a configuration for performing the operation, the air-conditioning operation can be started immediately without impairing the comfort of the air-conditioning due to the mixing of odorous components.

  Therefore, according to the fifth characteristic configuration, even if odorous components may adhere to the humidity control body, such odorous components can be removed, but air conditioning by mixing of odorous components is possible. When there is little risk of impairing comfort, the air conditioning operation can be started immediately, and an easy-to-use air conditioner can be provided.
