JP 2001-116276 A

In the conventional bathroom dryer, although the blowing direction of the drying air is changed with time in the drying target area, there is a possibility that the drying target may not be efficiently dried or the drying target is not uneven. There was a possibility that it could not be dried, and improvement was desired.
That is, in the drying target area, there are many places where it is difficult to dry due to high humidity and the like, and there are many places where drying is easy due to low humidity etc., but conventionally, the blowing direction of the drying air is Since it is changed in a uniquely determined form with the passage of time, there is a possibility that it cannot be efficiently dried and there is a possibility that uneven drying occurs.

In the case of drying an object to be dried such as laundry, even if the blowing direction of the drying air is changed with time in the region to be dried, the place where the object to be dried easily exists The air to be blown out is excessive and the air to be blown out is insufficient for the place where the object to be dried is difficult to dry. There was a possibility that the state could not be efficiently dried.
In addition, when drying a bathroom tub or wall as an object to be dried, there are places where it is easy to dry and places where it is difficult to dry. There was a possibility that the dried product could not be efficiently dried in a uniform state.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a bathroom dryer capable of drying an object to be dried efficiently and without unevenness.

The bathroom dryer of the present invention sucks the air in the bathroom and discharges it to the outside, and sucks and heats the air in the bathroom and then blows it as drying air to the drying target area in the bathroom. ,
A blowing direction changing means for changing a blowing direction of the drying air blown to the drying target area by the ventilation function-equipped ventilation means;
The ventilation function-equipped ventilation means and the control means for controlling the operation of the blowing direction changing means are provided, the first characteristic configuration is
A humidity detection sensor for detecting the humidity of the air in the bathroom sucked by the ventilation function-equipped ventilation means is provided,
The control means is
When a drying operation command is instructed, a set time for inspection with respect to each of a plurality of drying blowing directions in which the blowing direction of the drying air is directed to the drying target region and different from each other. The inspection blowing direction changing process for operating the blowing direction changing means so as to be directed one by one, and the detection of the humidity detection sensor in a state where the blowing direction of the drying air is directed to each of the plurality of drying blowing directions Based on the information, performing a humidity inspection process for obtaining an initial humidity for each of the plurality of drying blowing directions,
A blowing direction setting process for setting the blowing direction of the drying air to any one of the plurality of drying blowing directions based on the initial humidity and the blowing direction setting condition for each of the plurality of drying blowing directions. And, based on the setting result of the blowing direction setting process, the blowing direction changing means so that the blowing direction of the drying air is directed to the drying blowing direction set out of the plurality of drying blowing directions. It is characterized by the point comprised so that the blowing direction change process for drying which operates may be performed.

  That is, when the drying operation command is instructed, the control means inspects each of a plurality of drying blowing directions determined so that the drying air blowing direction is directed toward the drying target region and different from each other. Inspection direction change processing for operating the blowing direction changing means so as to be directed for a set time, and detection of the humidity detection sensor in a state where the blowing direction of the drying air is directed to each of the plurality of drying blowing directions Based on the information, a humidity inspection process for determining the initial humidity for each of the plurality of drying blowing directions is executed.

  That is, the drying air blown toward the drying target area by the ventilation function-equipped ventilation means passes through the drying target area, and is then sucked again as air in the bathroom by the ventilation function-equipped ventilation means. In the state where the blowing direction of the drying air is directed to each of the plurality of drying blowing directions by performing the inspection blowing direction changing process and the humidity checking process, the bathroom is sucked by the ventilation means with ventilation function The humidity of the air inside is detected by a humidity detection sensor, and the initial humidity for each of the plurality of drying blowing directions is obtained based on the detection information.

The initial humidity for each of the plurality of drying blowing directions is the humidity of the object to be dried in the drying air when the drying air blowing direction is in the drying blowing direction. Is a value corresponding to the size (hereinafter referred to as drying load).
That is, the initial humidity for each of the plurality of drying blowing directions represents a drying load when the drying air blowing direction is directed to the drying blowing direction.

  In addition, after the control means executes the inspection blowing direction change process and the humidity inspection process, the control unit determines the blowing direction of the drying air based on the initial humidity and the blowing direction setting condition for each of the plurality of drying blowing directions. Based on the setting result of the blowing direction setting process and the blowing direction setting process set to any one of the plurality of drying blowing directions, the drying air blowing direction is set from among the plurality of drying blowing directions. The drying blowing direction changing process for operating the blowing direction changing means is performed so as to be directed to the drying blowing direction, and the object to be dried existing in the drying target region is dried.

  That is, the initial humidity for each of the plurality of drying blowing directions represents a drying load when the drying air blowing direction is directed to the drying blowing direction as described above, and thus the initial humidity is large. The state in which the drying air is blown toward the drying blowing direction is present in the region to be dried by making the amount of drying air larger than the state in which the drying air is blown toward the drying blowing direction having a low initial humidity. The object to be dried can be efficiently and evenly dried, but the object to be dried existing in the drying target area can be efficiently and evenly dried by the blowing direction setting process. By setting the blowing direction of the drying air and changing the blowing direction of the drying air in the drying blowing direction changing process based on the setting result, the drying target existing in the drying target area is changed. Efficiently, and it will be able to dry in the absence of unevenness.

Incidentally, the blowing direction setting process in which the blowing direction of the drying air is set to any one of the plurality of drying blowing directions is a process for determining the blowing direction of the drying air and the timing of ending the blowing direction. That is, by this blowing direction setting process, the blowing direction of the drying air is set, and the timing for ending the blowing direction with the passage of time is set.
And as the blowing direction of the drying air set by the blowing direction setting process, when it is determined so as to be sequentially directed to all of the plurality of drying blowing directions, or when it is determined as a part of the plurality of drying blowing directions There is.
The timing for ending the set drying direction of the drying air with the passage of time refers to the case where the end timing is determined based on the elapsed time or the progress of drying is confirmed based on detection information from the humidity detection sensor. In some cases, the end timing is determined.

  In short, according to the first characteristic configuration of the present invention, it is possible to provide a bathroom dryer capable of drying an object to be dried efficiently and without unevenness.

The second feature configuration of the present invention is in addition to the first feature configuration described above.
The blowing direction setting condition is such that the drying air direction becomes the highest humidity among the initial humidity for each of the plurality of drying air blowing directions among the plurality of drying air blowing directions. It is characterized in that it is set to a condition that is preferentially set as the blowing direction.

  That is, the blowing direction setting condition is the blowing direction for drying air, which is the highest humidity among the initial humidity for each of the plurality of drying blowing directions among the plurality of drying blowing directions. As a result of the blow direction setting process, the blow direction of the drying air is set to the highest humidity among the initial humidity for each of the plurality of dry blow directions. It is set with priority over the blowing direction.

  In this way, the drying air blowing direction is set in preference to the drying blowing direction that is the highest humidity among the initial humidity for each of the plurality of drying blowing directions, and the drying blowing direction is set to the drying blowing direction. By blowing out the air for drying, it is possible to prioritize drying in the direction of blowing for drying with a large drying load, so that the object to be dried can be dried more efficiently and the dried substance can be made more uniform. It becomes easy to dry to the state.

  In other words, when the drying air blowing direction is set to one of a plurality of drying blowing directions and the drying air is blown out, the drying with respect to the drying load in the drying blowing direction can be accurately performed. However, in addition, since it also contributes to drying with respect to the drying load in the other drying blowing directions, the blowing direction of the drying air is set to the initial humidity for each of the plurality of drying blowing directions. Precisely set the drying blowing direction that gives the highest humidity, and blow the drying air toward the drying blowing direction, so that the drying load in the drying blowing direction with high initial humidity can be accurately dried. While performing, it becomes possible to perform drying with respect to the drying load in the drying blowing direction, drying the object to be dried more efficiently, and easily drying the dried object to a more uniform state By it becomes that.

  In short, according to the second characteristic configuration of the present invention, in addition to the operation and effect of the first characteristic configuration described above, it is possible to dry the object to be dried more efficiently and to dry the dried substance in a more uniform state. A bathroom dryer can be provided.

The third feature configuration of the present invention is in addition to the first feature configuration described above,
The blow direction setting condition is such that the drying air blowing direction is sequentially directed to each of the plurality of drying blowing directions and one of the plurality of drying blowing directions. It is determined to be maintained until it is satisfied, and is set to a condition that determines the order of the plurality of drying blowing directions based on the initial humidity for each of the plurality of drying blowing directions. It is characterized by that.

  That is, the end condition is satisfied when the blowing direction setting condition is such that the drying air blowing direction is sequentially directed to each of the plurality of drying blowing directions and one of the plurality of drying blowing directions. Therefore, by the blowing direction setting process, the blowing air blowing direction is sequentially directed to each of the plurality of drying blowing directions and the plurality of drying blowing directions. When the end direction is satisfied, it is determined to maintain the state toward the end until the end condition is satisfied. Based on the setting result, the blowing direction of the drying air is determined to satisfy the end condition by the blowing direction setting process. In the form changed to the next drying blowing direction, the direction is sequentially directed to each of the plurality of drying blowing directions.

  Thus, since the blowing direction of the drying air is sequentially directed to each of the plurality of drying blowing directions, the entire object to be dried existing in the drying target region can be dried well. It will be a thing.

  The blowing direction setting condition is set to a condition for determining the order of directing the blowing direction of the drying air to each of the plurality of drying blowing directions, based on the initial humidity for each of the plurality of drying blowing directions. Therefore, for example, the order in which the blowing direction of the drying air is directed is set so that the drying blowing direction in which the initial humidity is large is earlier than the drying blowing direction in which the initial humidity is small, and the drying blowing direction in which the initial humidity is large. The order of directing the blowing direction of the drying air to each of the plurality of drying blowing directions, such as promoting drying in other blowing blowing directions while accurately drying Can be efficiently dried, and the order can be set so that the object to be dried can be dried in a uniform state.

  In short, according to the third characteristic configuration of the present invention, in addition to the function and effect of the first characteristic configuration, the entire object to be dried existing in the region to be dried can be satisfactorily dried. It is possible to provide a bathroom dryer capable of drying an object efficiently and without unevenness.

The fourth feature configuration of the present invention is in addition to the third feature configuration,
The blowing direction setting condition is such that the order in which the blowing direction of the drying air is directed to each of the plurality of drying blowing directions is the drying blowing having a high initial humidity among the plurality of drying blowing directions. It is characterized in that the direction is set to the condition determined in the earlier order as the direction.

  That is, in the blowing direction setting condition, the order in which the blowing direction of the drying air is directed to each of the plurality of drying blowing directions, the drying blowing direction having a higher initial humidity among the plurality of drying blowing directions comes first. The order of directing the blowing direction of the drying air in the direction of each of the plurality of drying blowing directions by the blowing direction setting process, among the plurality of drying blowing directions, The higher the initial humidity, the higher the direction of the drying blowing direction.

  In this way, the order in which the blowing direction of the drying air is directed to the respective directions of the plurality of drying blowing directions is determined in the order of the drying blowing direction in which the initial humidity is higher among the plurality of drying blowing directions. Since the drying air is blown out toward each of the plurality of drying blowing directions, drying in the drying blowing direction with a large drying load can be prioritized so that the object to be dried is more efficient. It dries well, and it becomes easy to dry the dried product in a more uniform state.

  In other words, when the drying air blowing direction is set to one of a plurality of drying blowing directions and the drying air is blown out, the drying with respect to the drying load in the drying blowing direction can be accurately performed. However, in addition, since it also contributes to drying with respect to the drying load in other drying blowing directions, the order of directing the blowing direction of the drying air to each of the plurality of drying blowing directions is plural. The initial humidity is determined by blowing out the drying air toward each of the plurality of drying blowing directions by setting the drying blowing direction with higher initial humidity to the conditions determined in the preceding order. However, while accurately drying with respect to the drying load in the drying blowing direction, drying with respect to the drying load in other drying blowing directions can be performed, and the object to be dried is dried more efficiently. Ma The dried product is of becomes easy to dry even the absence unevenness.

  In short, according to the fourth characteristic configuration of the present invention, in addition to the operational effects of the third characteristic configuration described above, the material to be dried can be dried more efficiently, and the dried material can be easily dried to a more uniform state. A bathroom dryer can be provided.

In addition to the third or fourth feature configuration described above, the fifth feature configuration of the present invention includes:
Based on detection information of the humidity detection sensor in a state in which the control unit directs the drying air blowing direction to one of the plurality of drying blowing directions during execution of the drying blowing direction changing process. , Configured to execute a humidity detection process during drying to obtain a renewal humidity for the drying blowing direction,
After the blowing direction setting conditions direct the blowing direction of the drying air to all of the plurality of drying blowing directions, the renewal humidity for each of the plurality of drying blowing directions is set to the plurality of drying directions. It replaces with the said initial humidity about each of the air blowing directions, and the point which is set to the conditions which determine the blowing direction of the said drying air based on the initial humidity after this replacement is characterized.

  That is, during the execution of the drying blowing direction changing process, the control means executes a humidity detection process during drying, and detects the humidity in a state where the blowing direction of the drying air is directed to one of the plurality of drying blowing directions. Based on the detection information of the sensor, the renewal humidity in the blowing direction for drying is obtained.

  Then, after the blowing direction setting condition directs the drying air blowing direction to all of the plurality of drying blowing directions, the renewal humidity for each of the plurality of drying blowing directions is set to the plurality of drying blowing directions. Since the initial humidity for each is replaced with a condition for determining the blowing direction of the drying air based on the initial humidity after the replacement, a plurality of drying air blowing directions are set by the blowing direction setting process. After all of the drying blowing directions are directed, the order of directing the drying air blowing direction to each of the plurality of drying blowing directions is determined based on the replaced initial humidity. Will continue.

  In other words, after the drying air blowing direction is directed to all of the plurality of drying blowing directions, the initial humidity obtained in the temperature inspection process is replaced with the renewing humidity obtained in the drying humidity detection process. On the basis of the initial humidity, the order in which the blowing direction of the drying air is directed to each of the plurality of drying blowing directions is determined, and the blowing of the drying air is continued.

  Thus, after the drying air blowing direction is directed to all of the plurality of drying blowing directions, the drying air blowing direction is changed to the plurality of drying blowing directions based on the initial humidity replaced with the renewal humidity. Therefore, the air blowing direction of the drying air is continued and the air blowing direction of the drying air is directed to each of the plurality of drying air blowing directions. The drying can be continued while appropriately setting according to the change in the drying load in each of the blowing directions.

  In addition, based on the initial humidity obtained in the temperature inspection process, the order in which the blowing direction of the drying air is directed to each of the plurality of drying blowing directions is determined, and drying is performed while blowing the drying air. If it does, the drying with respect to the drying load in each of the plurality of drying blowing directions will be performed, and the progress of the drying with respect to the drying load in each of the plurality of drying blowing directions is in the plurality of drying blowing directions. Although it is not the same about each and it fluctuates, the dry load which considered the fluctuation | variation is calculated | required as renewal humidity.

  Accordingly, after the drying air blowing direction is directed to all of the plurality of drying blowing directions, the drying air blowing direction is set to each of the plurality of drying blowing directions based on the initial humidity replaced with the renewal humidity. The order of directing the blowing direction of the drying air to each direction of the plurality of drying blowing directions is appropriately adjusted according to the change in the drying load in each of the plurality of drying blowing directions. Since it can be set, the material to be dried can be dried well.

  In short, according to the fifth characteristic configuration of the present invention, in addition to the operational effects of the third or fourth characteristic configuration, the order in which the blowing direction of the drying air is directed to each of the plurality of drying blowing directions is dried. By setting according to the degree of progress, it is possible to provide a bathroom dryer that can dry an object to be dried satisfactorily.

In addition to the fifth feature configuration, the sixth feature configuration of the present invention includes:
The end condition in the blowing direction setting condition is characterized in that the renewal humidity is set to a condition that lowers the initial humidity in the drying blowing direction of the next rank.

  That is, the end condition for ending maintaining the blowing direction of the drying air in any of the plurality of drying blowing directions is that the renewal humidity required in the humidity detection process during drying is the next order. Since the condition is set to lower than the initial humidity in the drying blowing direction, when drying is performed with the drying air blowing direction directed to one of the drying blowing directions, When the renewal humidity for the drying blowing direction is lower than the initial humidity for the next drying blowing direction, the drying air blowing direction is changed to the next drying blowing direction. .

  Thus, when drying is performed in a state where the blowing direction of the drying air is directed to one of the plurality of drying blowing directions, the renewal humidity in the drying blowing direction is the next rank of drying. Since the drying air blowing direction is changed to the drying blowing direction of the next rank when the initial humidity in the blowing blowing direction is lowered, the drying air blowing direction is changed to any one of a plurality of drying blowing directions. When drying in a state facing the crab, it is possible to prevent the object to be dried in the blowing direction for drying from drying too much than the object to be dried in the blowing direction for other drying, The object to be dried can be accurately dried in a uniform state.

  In short, according to the sixth characteristic configuration of the present invention, in addition to the operational effects of the fifth characteristic configuration, it is possible to provide a bathroom dryer that can accurately dry an object to be dried in a uniform state.

In addition to the third or fourth characteristic configuration described above, the seventh characteristic configuration of the present invention includes:
After the control means directs the drying air blowing direction to all of the plurality of drying blowing directions, the inspection blowing direction changing process and the humidity checking process are executed again. ,
After the blowing direction setting condition directs the blowing direction of the drying air to all of the plurality of drying blowing directions, the plurality of drying blowing directions obtained by the humidity inspection process performed again is performed. Based on the initial humidity for each, the condition is set to determine the blowing direction of the drying air.

That is, after the control means directs the drying air blowing direction to all of the plurality of drying blowing directions, the inspection blowing direction changing process and the humidity inspection process are executed again.
Then, after the blowing direction setting condition directs the blowing direction of the drying air to all of the plurality of drying blowing directions, each of the plurality of drying blowing directions obtained by the humidity inspection process performed again is performed. Based on the initial humidity, it is set to a condition for determining the blowing direction of the drying air.After the blowing direction setting process has turned the blowing direction of the drying air to all of the plurality of drying blowing directions, The blowing direction of the drying air is determined based on the initial humidity for each of the plurality of drying blowing directions obtained by the executed humidity inspection process.

  Thus, after directing the blowing direction of the drying air to all of the plurality of drying blowing directions, the blowing direction changing process for inspection and the humidity inspection process are performed again, and the humidity inspection process performed again. Since the drying air blowing direction is determined based on the initial humidity for each of the plurality of drying blowing directions obtained by the above, the drying air blowing direction is directed to each of the plurality of drying blowing directions. It is possible to continue drying while appropriately setting the rank according to the change in the drying load in each of the plurality of drying blowing directions.

  In addition, based on the initial humidity obtained in the temperature inspection process, the order in which the blowing direction of the drying air is directed to each of the plurality of drying blowing directions is determined, and drying is performed while blowing the drying air. If it does, the drying with respect to the drying load in each of the plurality of drying blowing directions will be performed, and the progress of the drying with respect to the drying load in each of the plurality of drying blowing directions is in the plurality of drying blowing directions. Although it is not the same about each, and it fluctuates, the dry load which considered the fluctuation is calculated | required by the humidity test process performed again.

  Therefore, after directing the drying air blowing direction to all of the drying blowing directions, the drying air blowing direction is set to the plural drying directions on the basis of the initial humidity obtained by the humidity inspection process performed again. Since the order in which the blowing direction is directed to each direction is determined, the order in which the blowing direction of the drying air is directed to each direction of the plurality of drying blowing directions is determined according to the drying load in each of the plurality of drying blowing directions. Since it can set appropriately according to a change, a to-be-dried object can be dried favorably.

  In short, according to the seventh characteristic configuration of the present invention, in addition to the operational effects of the third or fourth characteristic configuration, the order in which the blowing direction of the drying air is directed to each of the plurality of drying blowing directions is dried. By setting according to the degree of progress, it is possible to provide a bathroom dryer that can dry an object to be dried well.

The eighth feature of the present invention, in addition to any of the fifth to seventh features described above,
The control means operates the ventilation function-equipped ventilation means in a ventilation function stop state in which the drying function is blown out in a ventilation function stop state at each periodic setting determination timing, and the ventilation function stop state is determined as a determination time. When the humidity detected by the humidity detection sensor rises more than the set value for end determination while continuing, a dry end determination process is performed to determine that it is in an undried state until it is determined not to be in the undried state The blowing direction setting process and the drying blowing direction changing process are continuously executed.

  That is, at each periodic setting determination timing, the control means executes the drying end determination process, and continues the blowing direction setting process and the drying blowing direction change process until it is determined that it is not in an undried state. By executing, the material to be dried is dried to an appropriate dry state.

  The drying end determination process is performed while the ventilation function-equipped ventilation means is operated in the ventilation function stopped state in which the drying air is blown out in the ventilation function stopped state and the ventilation function stopped state continues for the determination time. When the detected humidity rises by more than the set value for end determination, it is determined that it is in an undried state, so that it is possible to appropriately determine whether it is in an undried state.

  In other words, when the ventilation function with ventilation function is operated with the ventilation function stopped and the ventilation function is stopped with the ventilation function stopped, the moisture evaporating from the object to be dried in the drying target area increases the humidity of the air in the bathroom. Therefore, when the drying load in the drying target area is large, that is, when the humidity of the object to be dried in the drying target area is high, the humidity of the air in the bathroom detected by the humidity detection sensor gradually increases greatly. When the drying load on the drying target area is small, that is, when the humidity of the object to be dried in the drying target area is small, the humidity of the air in the bathroom detected by the humidity detection sensor does not increase or gradually increases. Even if it increases, the increase amount becomes small.

Therefore, the humidity detected by the humidity detection sensor while the ventilation function with the ventilation function is operated in the ventilation function stopped state in which the drying air is blown out in the ventilation function stopped state and the ventilation function stopped state continues for the determination time. When the value rises above the set value for end determination, it can be determined that the drying load in the area to be dried is large, that is, that the object to be dried in the area to be dried is in an undried state.
By the way, the end determination set value is obtained and set in advance through experiments or the like.

  In short, according to the eighth feature configuration of the present invention, in addition to the operational effects of any of the fifth to seventh feature configurations, it is appropriately determined whether the object to be dried in the drying target region is in an undried state. On the other hand, by continuously executing the blowing direction setting process and the drying blowing direction changing process until the undried state is eliminated, it is possible to provide a bathroom dryer capable of drying an object to be dried in an appropriate dry state.

  The ventilation fan 11 sucks air through a ventilation passage T formed inside the main body casing 7, sucks air in the bathroom from the suction port K of the grill plate 8, and passes through an exhaust duct 25 extended to the outside. The sucked air is exhausted to the outside.

Accordingly, the bathroom dryer A of the present embodiment is configured to perform a drying operation, a heating operation, a ventilation operation, and a mist operation.
That is, the air in the bathroom is sucked and discharged outside by operating the circulation fan 9 and the ventilation fan 11 in a state where the heat medium from the heat source unit N is passed through the heat exchanger 10 for air heating. In addition, a drying operation can be performed in which the air in the bathroom is sucked and heated and blown into the bathroom as drying air.

  In addition, the ventilation fan 11 is stopped, and the circulation fan 9 is operated in a state where the heat medium from the heat source unit N is passed through the air heating heat exchanger 10, thereby sucking and heating the air in the bathroom. Thus, the heating operation can be performed in which the air is blown into the bathroom as heating air.

  Further, the air in the bathroom is sucked by operating the ventilation fan 11 with the circulation fan 9 stopped and the flow of the heat medium from the heat source unit N to the air heating heat exchanger 10 stopped. Ventilation operation to discharge to the outside can be performed.

  Furthermore, by opening the water supply electromagnetic valve 20, a mist operation in which hot water from the water supply channel 12 is ejected from the mist nozzle 13 can be performed, and the heat medium from the heat source unit N is transferred to the heat exchanger air 14 for mist.

If it is, it will be in a cold water mist driving | running state.

  Incidentally, the bathroom dryer A of the present embodiment operates the circulation fan 9 and the ventilation fan 11 in a state where the heat medium from the heat source unit N is passed through the air heating heat exchanger 10 as described above. In this embodiment, the ventilation with ventilation function that sucks out the air in the bathroom and discharges it to the outside and sucks and heats the air in the bathroom and then blows it out into the bathroom as heating air. The means J is composed mainly of the circulation fan 9, the air heating heat exchanger 10, and the ventilation fan 11.

As shown in FIG. 1, the above-described movable louver 15 changes the blowing direction of the drying air blown to the drying target area E inside the bathroom Y in the drying operation. Further, the electric motor 25 for changing the direction is configured to be reciprocally swung around the rotation axis Z along the horizontal direction.
That is, the movable louver 15 is formed in a long cylindrical shape along the rotational axis direction, and is configured to blow out air over a wide range along the rotational axis direction.
Then, an electric motor 25 is disposed on one end side of the movable louver 15, and the electric motor 25 changes the blowing direction of the drying air into a plurality of drying blowing directions, that is, five blowing directions, as shown in FIG. 3. The movable louver 15 is configured to swing in order to change the drying blowing directions L4 to L8.

In the present embodiment, among the five drying blowing directions L4 to L8, the direction of L6 is determined to go directly below, the direction of L5 is set to go to the lower left, and the direction of L4 is set to L5. The direction of L7 is determined to face further left, the direction of L7 is determined to face lower right, and the direction of L8 is determined to face further right than L7.
In the following description, the L6 direction is referred to as a directly downward direction, the L5 direction is referred to as a lower left direction, the L4 direction is referred to as a left direction, the L7 direction is referred to as a lower right direction, and the L8 direction is referred to as a right direction.

Therefore, in the present embodiment, the blowing direction changing means F is configured by the movable louver 15 and the electric motor 25.
Incidentally, the movable louver 15 is swung by the electric motor 25 in order to change the blowing direction of the heating air even when performing the heating operation.
Moreover, although not illustrated, the movable louver 15 is configured to be operated in a lateral posture (hereinafter, abbreviated as a closed posture) that closes the air passage S.

In the present embodiment, the drying target area E inside the bathroom Y is an area in which an object to be dried such as laundry is placed in a posture suitable for drying, and the area E supports the object to be dried. A pair of rod-like bodies B is provided between the opposing wall surfaces of the bathroom Y in a posture along the rotational axis direction of the movable louver 15.
In addition, the rod-shaped body B is constructed with a support provided on the wall surface of the bathroom Y in a state in which both ends thereof are supported, and can be removed from the support and stored when not in use. Yes.

As shown in FIG. 2, a humidity detection sensor 26 that detects the humidity of the air in the bathroom sucked through the suction port K of the grill plate 8 is provided in the main body casing 7.
As shown in FIG. 4, the humidity sensor 26 includes a humidity measuring element G1 configured using an NTC thermistor sealed in glass and a temperature correcting element configured using an NTC thermistor sealed in glass. The sensor unit G provided with G2 is configured as a main part.

The humidity measuring element G1 and the temperature correcting element G2 are configured to have the same temperature characteristics.
Then, the humidity measuring element G1 is provided in a state where the outer periphery is opened so as to come into contact with the air sucked from the bathroom Y (measurement air), and the temperature correction element G2 is dried air (absolute humidity). Is housed in a sealed state in a metal case sealed with zero air.

  Then, a bridge circuit is formed by the humidity measuring element G1, the temperature correcting element G2, and the pair of resistors R1 and R2, and at both ends of the humidity measuring element G1 and the temperature correcting element G2 connected in series, A set voltage is applied using the power source H and the fixed resistor R3, and an output voltage Vm having a value corresponding to the absolute humidity of the measurement air contacting the humidity measuring element G1 is output between the pair of output terminals D. It is configured as follows.

That is, the humidity measuring element G1 and the temperature correcting element G2 generate heat when a current is applied, but when the absolute humidity of the measuring air is greater than zero, the temperature of the humidity measuring element G1 is the temperature correcting element. Since the humidity measuring element G1 and the temperature correcting element G2 are configured using NTC thermistors, the resistance of the humidity measuring element G1 is larger than the resistance of the temperature correcting element G2. Become.
Therefore, the output voltage Vm output between the pair of output terminals D changes in accordance with the change in the absolute humidity of the measurement air. By measuring this output voltage Vm, the absolute humidity of the measurement air is reduced. It can be measured.

  In the present embodiment, as described above, the dryer control means 1 functions as a control means for controlling the operation of the ventilation function-equipped ventilation means J and the blowing direction changing means F, and the bathroom remote controller 2 performs the drying operation. When the command is issued, the above-described drying operation is executed. During the execution, the blowing direction of the drying air is automatically set based on the detection information of the humidity detection sensor 26 and the blowing direction setting condition. Is configured to change automatically.

That is, when the drying operation command is instructed, the dryer control means 1 first executes a preliminary drying process.
In this preliminary drying process, the blowing direction of the drying air is directed to each of a plurality of drying blowing directions determined so as to be directed to the drying target region E and different from each other for each set time for the preliminary drying. And a process of operating the blowing direction changing means F.
In the present embodiment, the plurality of drying blowing directions are the above-described five drying blowing directions L4 to L8, and the set time for preliminary drying is set to 5 minutes, for example.
The order in which the blowing direction of the drying air is directed to the five drying blowing directions L4 to L8 is the order of the directly downward direction L6, the lower left direction L5, the left direction L4, the lower right direction L7, and the right direction L8.

When the preliminary drying process is completed, the dryer control unit 1 executes the inspection blowing direction change process and the humidity inspection process.
In the inspection blowing direction changing process, the blowing direction of the drying air is directed to each of a plurality of drying blowing directions determined to be different from each other toward the drying target region E by a set time for inspection. Thus, it is the process which operates the blowing direction change means F.
In the present embodiment, the plurality of drying blowing directions are the above-described five drying blowing directions L4 to L8, and the set time for inspection is set to 5 minutes, for example.
The order in which the blowing direction of the drying air is directed to the five drying blowing directions L4 to L8 is the order of the directly downward direction L6, the lower left direction L5, the left direction L4, the lower right direction L7, and the right direction L8.

  The humidity inspection process is based on the detection information of the humidity detection sensor 26 in the state where the blowing direction of the drying air is directed to each of the five blowing directions L4 to L8. The process for obtaining the initial humidity for the will be executed.

Specifically, in the state where the blowing direction of the drying air is directed to each of the drying blowing directions L4 to L8, the detection information of the humidity detection sensor 26 is sampled at a set sampling interval (100 mS), and the sampling is performed. The moving average value is obtained, and the finally obtained moving average value is set as the initial humidity in each of the drying blowing directions L4 to L8 within the set time for inspection.
By the way, in this embodiment, every time the detection information of the humidity detection sensor 26 is sampled for obtaining the moving average value, four samplings excluding the maximum and minimum sampling values among the past six sampling values are sampled. The average of the values is obtained.

In addition, the form which calculates | requires initial humidity may replace with the structure which calculates | requires a moving average value, and may obtain | require the simple average value of the sampling value sampled by the setting sampling interval as initial humidity within the setting time for a test | inspection. .
In the case of this embodiment, the average of the sample values of the second half of the set time for inspection (for example, the second half of the second half) is obtained, and the first half of the set time for inspection is calculated. It is conceivable that the sample value of (for example, the first half of 3 minutes) is not used for the data for obtaining the average value.

  Incidentally, when the dryer control means 1 obtains the initial humidity for each of the five drying blowing directions L4 to L8, a difference is detected in the initial humidity for each of the five drying blowing directions L4 to L8. If not, the humidity inspection process is repeated.

After completing the inspection blowing direction changing process and the humidity inspection process, the dryer control means 1 executes a blowing direction setting process and a drying blowing direction changing process.
In the blowing direction setting process, based on the initial humidity and the blowing direction setting condition for each of the five drying blowing directions L4 to L8, the blowing direction of the drying air is selected from any of the five drying blowing directions L4 to L8. The drying blowing direction changing process is a process of setting the blowing direction of the drying air among the plurality of drying blowing directions L4 to L8 based on the setting result of the blowing direction setting process. It is the process which operates the blowing direction change means F so that it may face in the blowing direction for drying.

  In the present embodiment, the above-described blowing direction setting conditions are such that the drying air blowing direction is sequentially directed to each of the five drying blowing directions L4 to L8 and the five drying blowing directions L4 to L8. Each direction of the five drying blowing directions is determined based on the initial humidity for each of the five drying blowing directions L4 to L8. It is set as a condition that determines the order of the turn.

Specifically, the blow direction setting condition is the initial order in which the blowing direction of the drying air is directed to each of the five drying blowing directions L4 to L8, among the five drying blowing directions L4 to L8. The higher the humidity, the higher the drying direction, is set to the condition determined in the previous order.
By the way, when the same values exist for the initial humidity in each of the five drying blowing directions L4 to L8, a predetermined priority order, that is, directly below L6, bottom left L5, left L4, bottom right The blowing direction of the drying air is determined in the order of the direction L7 and the right direction L8.

In the present embodiment, when there is an initial humidity in the five drying blowing directions L4 to L8 that is lower than the set humidity, the drying blowing direction is effective for drying an object to be dried. Therefore, the drying blowing direction is excluded from the direction selected as the drying air blowing direction.
That is, the blowing direction setting condition is excluded from the direction in which the drying blowing direction that is lower than the set humidity is selected as the blowing direction of the drying air among the initial humidity for the five drying blowing directions L4 to L8. The condition is set to

Further, the detection information of the humidity detection sensor in a state where the drying control unit 1 directs the drying air blowing direction to one of the five drying blowing directions L4 to L8 during execution of the drying blowing changing process. The drying humidity detection process for obtaining the renewal humidity in the blowing direction for drying is executed based on the above.
Incidentally, the form for obtaining the renewal humidity in the humidity detection process during drying is performed in the same form as the form for obtaining the initial humidity in the humidity inspection process described above.

Then, after the blowing direction setting condition directs the drying air blowing direction to all the five blowing blowing directions L4 to L8, the renewal humidity for each of the five drying blowing directions L4 to L8 is changed to five. Instead of the initial humidity for each of the drying blowing directions L4 to L8, the conditions are set to determine the blowing direction of the drying air based on the replaced initial humidity.
That is, every time when the blowing direction of the drying air is directed to all of the five drying blowing directions L4 to L8, the renewal humidity is replaced with the initial humidity, and based on the replaced initial humidity. The blowing direction setting process is executed, and the drying blowing direction changing process is executed based on the setting result of the blowing direction setting process.

In addition, the above-described end condition in the blowing direction setting condition is set such that the renewal humidity is lower than the initial humidity in the drying blowing direction of the next rank.
That is, the end condition is satisfied when the drying air blowing direction is sequentially directed to each of the five drying blowing directions L4 to L8 and any one of the five drying blowing directions L4 to L8. In order to maintain the above, the end condition is set such that the renewal humidity is lower than the initial humidity in the drying blowing direction of the next rank.
Accordingly, when the renewal humidity is lower than the initial humidity in the drying blowing direction of the next rank, the blowing direction of the drying air is changed to the next rank direction among the plurality of drying blowing directions L4 to L8. Will be.
By the way, in this embodiment, when the state in which the renewal humidity is lower than the initial humidity in the next blowing drying direction continues for a set time (for example, 30 seconds), the renewing humidity is dried in the next order. It is comprised so that it may discriminate | determine that it fell from the initial humidity about the blowing direction.

By the way, in the state where the blowing direction of the drying air is directed to the drying blowing direction having the lowest rank among the five drying blowing directions L4 to L8, there is no drying blowing direction of the next rank, In this embodiment, the renewal humidity detected in the state in which the blowing direction of the drying air is directed to the drying blowing direction with the lowest rank among the five blowing blowing directions L4 to L8, and the five drying drying directions Among the blowing directions L4 to L8, the highest renewal humidity among the renewal humidity for the four dry blowing directions that has already become the blowing direction of the drying air and the renewal humidity has already been obtained, It is configured to compare.
That is, the renewal humidity has already been obtained for the renewal humidity detected in the state where the dry air blow direction is directed to the dry blow direction with the lowest rank among the five dry blow directions L4 to L8. If the state of decreasing the highest renewal humidity among the renewal humidity for the four drying blowing directions is continued for a set time (for example, 30 seconds), the renewing humidity is the initial for the next drying blowing direction. It is configured to determine that the state is lower than the humidity.

  Incidentally, in the state where the blowing direction of the drying air is directed to the drying blowing direction having the lowest rank among the five drying blowing directions L4 to L8, the condition is set as a condition for ending the state. (E.g., 2 minutes) The time when the drying air is blown out in the second drying blowing direction from the lowest ranking among the five drying blowing directions L4 to L8. It is conceivable that the condition is terminated when the same time has elapsed.

In carrying out this embodiment, it is also possible to omit the direction of blowing the drying air from the drying blowing direction with the lowest rank among the five drying blowing directions L4 to L8. it can.
That is, by directing the blowing direction of the drying air to the four drying blowing directions with the highest rank among the five drying blowing directions L4 to L8, the drying in the drying blowing direction with the lowest rank is also advanced. Therefore, the present embodiment is carried out in a form that omits directing the blowing direction of the drying air to the drying blowing direction having the lowest rank among the five drying blowing directions L4 to L8. May be.

Also, the dryer control means 1 operates the ventilation function-equipped ventilation means in a ventilation function stopped state in which the drying function is blown out in the ventilation function stopped state at each periodic setting determination timing, and the ventilation function is stopped. When the humidity detected by the humidity detection sensor 26 rises by more than the set value for end determination while the state continues for the determination time, a dry end determination process is performed to determine that the state is undried, and the undried state is not reached. Until it determines with it, it is comprised so that the said blowing direction setting process and the said blowing direction change process for drying may be performed continuously.
And when this drying completion determination process is performed, the movable louver 15 is continuously swung so as to continuously change the blowing direction of the drying air between the plurality of drying blowing directions L4 to L8. The movable louver 15 is configured to swing.

  That is, during the execution of the blowing direction setting process and the drying blowing direction changing process, the ventilation fan 11 is stopped at every periodic setting determination timing (for example, 20 minutes), and the ventilation function-equipped ventilation means J is switched to the ventilation function. While it is operated in a ventilation function stop state that blows dry air in the stop state, and the movable louver 15 performs a swing operation, while the ventilation function stop state continues for a determination time (for example, 7 minutes), When the humidity detected by the humidity detection sensor 26 rises by the end determination set value or more, it is determined that it is in an undried state.

Then, the blowing direction setting process and the drying blowing direction changing process are continuously executed until it is determined that it is not in an undried state. The ventilation means J is stopped.
Incidentally, the form for obtaining the humidity in the drying completion determination process is performed in the same form as the form for obtaining the initial humidity in the humidity inspection process described above.

As described above, when the drying operation command is instructed, the dryer control means 1 performs preliminary drying processing, inspection blowing direction change processing, humidity inspection processing, blowing direction setting processing, drying blowing direction change processing,
The drying operation is performed by sequentially executing processes such as a drying humidity detection process and a drying end determination process.

  In the drying operation, the drying direction of the drying air is sequentially changed from a plurality of (five) drying blowing directions L4 to L8 from the high initial humidity to the low one, thereby drying. An object to be dried that has been dried in the target area E can be dried efficiently and evenly.

  Further, by continuing the drying operation until the humidity of the bathroom Y does not rise even when the ventilation function is stopped, the object to be dried dried in the drying target region E can be reliably dried. .

Next, the drying operation process executed for the dryer control means 1 to perform the drying operation will be described based on a flowchart.
Incidentally, the dryer control means 1 sequentially executes other processes such as a communication process with the bathroom remote controller 2 and a communication process with the heat source machine control means 3 in addition to the drying operation process. However, in the following description, a flowchart when it is assumed that the dryer control means 1 performs only the drying operation process will be described.

As shown in FIG. 5, first, it is determined whether or not a drying operation command has been commanded (# 1). If a drying operation command has been commanded, a drying operation start process is executed (# 2).
In this drying operation start process, the movable louver 15 is swung from the closed posture so that the blowing direction of the drying air is in the direct downward direction L6, the circulation fan 9 and the ventilation fan 11 are operated, and the control means 3 for the heat source machine is operated. This is a process of communicating a heat medium request command and opening the thermal valve 18 to operate.

After the drying operation start process is executed, a preliminary drying process is executed (# 3), and then an inspection blowing direction change process and a humidity inspection process are executed (# 4).
Since the preliminary drying process, the inspection blowing direction change process, and the humidity inspection process are as described above, description thereof is omitted here.

Next, the blowing direction setting process (# 5) and the drying blowing direction changing process (# 6) for changing the blowing direction of the drying air based on the setting result of the blowing direction setting process are executed, and this drying is performed. During the execution of the blowing direction changing process, the drying humidity detection process is executed.
The blowing direction setting process will be described later, but the drying blowing direction changing process and the drying humidity detecting process are as described above, and thus the description thereof is omitted here.

Next, it is determined whether or not the operation time in which the drying operation is performed is within 6 hours (# 7), and if it is not within 6 hours, a stop process is performed (# 13).
In this stop process, the movable louver 15 is swung to a closed position, the circulation fan 9 and the ventilation fan 11 are stopped, a heat medium unnecessary command is communicated to the heat source unit control means 3, and the heat valve 18 is closed and operated. It is processing.

If it is determined in # 7 that the operation time is within 6 hours, it is next determined whether or not it is a periodic setting determination timing (for example, 20 minutes) (# 8), and it is not the setting determination timing Sometimes, the process proceeds to the blowing direction setting process of # 5.
When it is determined in # 8 that it is the setting determination timing, the ventilation fan 11 is stopped, the process of measuring the humidity increase value D based on the detection information of the humidity sensor 26 (# 9), and the drying The swing operation (# 10) of the movable louver that continuously swings the movable louver 15 so as to continuously change the air blowing direction between a plurality of (five) drying blowing directions L4 to L8. This is performed until the determination time (for example, 7 minutes) elapses (# 11).

When it is determined at # 11 that the determination time (for example, 7 minutes) has elapsed, it is determined whether the humidity increase value D is equal to or less than the set value (# 12), and the humidity increase value D is the set value. If not, the process proceeds to # 5 blowing direction setting process.
The set value to be compared with the humidity increase value D is a value for determining whether or not the object to be dried is dry, and is determined and set in advance by an experiment or the like.

  If it is determined in # 12 that the humidity increase value D is equal to or less than the set value, the stop process of # 13 is executed.

Next, the blowing direction setting process will be described based on the flowchart of FIG.
First, it is determined whether or not it is the order setting timing (# 21).
That is, when it is immediately after finishing the above-described inspection blowing direction changing process and the humidity inspection process, or blowing the drying air in all of the plural (five) drying blowing directions L4 to L8. If it is immediately after ending, it is determined that it is the order setting timing.

  When it is determined in # 21 that the order is set, it is determined whether or not it is the first process immediately after finishing the inspection blowing direction changing process and the humidity test process (# 22). In step # 23, a process of replacing the renewal humidity detected in the dry humidity inspection process with the initial humidity is performed.

Next, based on the initial humidity, order setting processing for setting the order in which the blowing direction of the drying air is directed to each of the plurality of drying blowing directions is executed (# 24).
In other words, in the present embodiment, the order in which the blowing direction of the drying air is directed to each of the plurality of drying blowing directions is higher in the drying blowing direction with the higher initial humidity than the plurality of drying blowing directions. It will be determined in the ranking.
Thereafter, the first drying blowing direction is set based on the result of the rank setting process (# 25).
Incidentally, based on the setting result, the blowing direction of the drying air is changed in the drying blowing direction changing process described above.

When it is determined at # 21 that the timing is not set, it is determined whether or not an end condition for ending the state is satisfied in a state where the blowing direction of the drying air is directed to any one of the plurality of blowing directions. (# 26).
That is, in this embodiment, when the state in which the renewal humidity is lower than the initial humidity in the drying blow direction of the next order is continued for a set time (for example, 30 seconds), the renewal humidity is dried in the next order. It is determined that the humidity is lower than the initial humidity in the blowing direction, and it is determined that the end condition is satisfied.

When it is determined at # 26 that the termination condition is satisfied, the drying air blowing direction is set to the drying blowing direction of the next order (# 27).
Incidentally, when the current drying blowing direction is the last drying blowing direction, the drying blowing direction is not set in # 27.

In addition, in this 1st Embodiment, after performing the preliminary drying process, the case where the blowing direction change process for an inspection and a humidity test process are performed was illustrated, However, Even if it implements in the form which a preliminary | backup drying process is abbreviate | omitted Good.
Moreover, in this 1st Embodiment, although the case where the five drying blowing directions L4-L8 were set as several drying blowing directions was illustrated, the form which sets the blowing blowing directions more than five, , You may carry out in the form which sets the blowing direction for drying fewer than five.

[Second Embodiment]
Next, although 2nd Embodiment is described, this 2nd Embodiment shows another form of the blowing direction setting process described in the said 1st Embodiment, The structure of the bathroom dryer A, and Of the control operations executed by the dryer control means 1, the control operations excluding the blowing direction setting process are the same as those in the first embodiment, and therefore only the blowing direction setting process will be described below.

  That is, in the second embodiment, the blowing direction setting condition is such that the blowing direction of the drying air is sequentially directed to each of the plural (five) drying blowing directions L4 to L8 and plural (five). Is determined so as to be maintained until the end condition is satisfied, and is directed to each of a plurality of (five) drying blowing directions L4 to L8. The rank is set to a condition determined in a predetermined rank.

  As the order in which the blowing direction of the drying air is directed to each of the plurality of (five) drying blowing directions L4 to L8, the predetermined order is the same as the preliminary drying process and the inspection blowing direction changing process described above. , Right down direction L6, lower left direction L5, left direction L4, lower right direction L7, and right direction L8.

In the second embodiment, the end condition in the blowing direction setting condition is set to a condition determined as the drying time tn for maintaining each of the drying blowing directions L4 to L8.
Specifically, the end condition is set to a condition in which the drying time for each of the plurality of drying blowing directions L4 to L8 is set longer as the initial humidity for each of the plurality of drying blowing directions L4 to L8 becomes higher. Has been.

In the present embodiment, the drying time for each of the plurality of drying blowing directions L4 to L8 is tn, the initial humidity for each of the plurality of drying blowing directions L4 to L8 is dn, and the set reference time is T. The drying time tn is determined by the following formula.
tn = T · dn / (d4 + d5 + d6 + d7 + d8)
In other words, the time obtained by proportionally dividing the set reference time T in proportion to the magnitude of the initial humidity dn for each of the plurality of drying blowing directions L4 to L8 becomes the drying time tn for each of the plurality of drying blowing directions L4 to L8. It is configured to be determined.

Next, the blowing direction setting process which the dryer control means 1 performs is demonstrated based on the flowchart of FIG.
In the blowing direction setting process in the second embodiment, a process for calculating the drying time of # 24-A is performed instead of the order setting process of # 24 in the first embodiment.
And the process which calculates the drying time of this # 24-A performs the process which calculates drying time tn using said formula.

When the explanation is added, it is first determined whether or not it is the order setting timing (# 21).
That is, immediately after finishing the above-described inspection blowing direction changing process and humidity inspection process, or immediately after finishing blowing the drying air toward all of the plurality of drying blowing directions L4 to L8. If it is, it is determined that it is the order setting timing.

  If it is determined in # 21 that the order is set, it is determined whether or not it is the first process immediately after the above-described inspection blowing direction change process and humidity test process are completed (# 22). If not, the process of replacing the renewal humidity detected in the above-described drying humidity inspection process with the initial humidity is executed (# 23).

Next, processing for obtaining the drying time tn for each of the plurality of drying blowing directions L4 to L8 is executed based on the initial humidity (# 24-A).
Thereafter, the first drying blowing direction is set based on a predetermined order as the order in which the blowing direction of the drying air is directed to each of the plurality of drying blowing directions L4 to L8 ( # 25).
Incidentally, based on the setting result, the blowing direction of the drying air is changed in the drying blowing direction changing process described above.
