Description

  The present invention relates to a bathroom drying apparatus, a bathroom drying method, and a program.

  There has been proposed a bathroom ventilation dryer that includes four outlets and wind direction plates provided at the respective outlets, and that allows the airflow emitted from the outlets to flow to the side walls of the bathroom by the wind direction plates (see, for example, Patent Document 1). The bathroom ventilation dryer described in Patent Literature 1 flows an air flow toward the side wall of the bathroom during the bathroom drying operation, and downwards toward the clothing disposed below the bathroom ventilation dryer during the clothes drying operation. Air flow to

Japanese Patent No. 3764220

  By the way, since the ceiling of the bathroom is difficult to clean, the frequency of cleaning tends to be lower than that of the side walls and the floor (for example, once a year), and the adhered dirt often remains without being removed. Therefore, mold mycelium is likely to occur in an environment with much moisture. In addition, once the mold mycelium is generated, mold spores released from the generated mold mycelium fall to the side wall and the floor surface, and as a result, the mold mycelium propagates on the side wall and the floor surface.

  However, although the bathroom ventilation dryer described in patent document 1 can flow an airflow toward the side wall or floor surface of a bathroom from a blower outlet, it cannot flow an airflow along a ceiling from a blower outlet. Therefore, in the bathroom ventilation dryer described in Patent Document 1, when water droplets adhere to the ceiling of the bathroom, it takes time to remove the adhered water droplets, and the ceiling is exposed to a moisture-rich environment for a long time. become. If it does so, it will become easy to generate | occur | produce mold | fungi hypha on a ceiling, and, as a result, there exists a possibility that mold | mycelium mycelium may propagate easily also on the side wall and floor surface of a bathroom.

  The present invention has been made in view of the above reasons, and aims to provide a bathroom drying apparatus, a bathroom drying method, and a program that can save energy while effectively suppressing the generation of mold mycelia. To do.

In order to achieve the above object, a bathroom drying apparatus according to the present invention comprises:
A suction port for inhaling air;
An air outlet that blows out air;
A blower for circulation that circulates air by sucking air from the suction port and blowing the sucked air from the blowout port;
A heat exchanger that adjusts the humidity of the air blown from the blowout port by heating or cooling the air blown from the blowout port;
An airflow adjusting unit for adjusting the airflow coming out of the outlet;
A controller for controlling the air flow control unit and controlling supply of a heat medium to the heat exchanger,
The controller is
Controlling the air flow adjusting unit so that the air flow flows along the ceiling of the bathroom, and supplying the heat medium to the heat exchanger;
A second process of controlling the airflow adjusting unit so that the airflow flows in a direction toward the side wall or floor of the bathroom and stopping the supply of the heat medium to the heat exchanger is performed.

  In the present invention, the control device controls the airflow adjusting unit so that the airflow flows along the ceiling of the bathroom during the first process, and supplies the heat medium to the heat exchanger. As a result, the ceiling can be quickly dried, and the time for the ceiling to stand at high humidity is shortened, so that mold mycelium is less likely to propagate on the ceiling. Therefore, generation | occurrence | production of the mold mycelium in the whole bathroom including a side wall and a floor surface can be suppressed effectively. In addition, during the second process, the control device controls the airflow adjusting unit so that the airflow flows in the direction toward the side wall or floor of the bathroom, and stops the supply of the heat medium to the heat exchanger. Thereby, since the electric power required for supply of the heat medium to a heat exchanger can be deleted, the power consumption of a bathroom drying apparatus can be suppressed significantly.

The bathroom 1 is provided with a bathtub 3 and a washing place 4. The bathroom drying apparatus 100 blows air from the ceiling CE toward the side wall WA or the floor surface FL. At the entrance of the bathroom 1, a door 21 having a gallery (air inlet) 22 is installed.

  As illustrated in FIG. 1B, the housing 101 includes a suction port 112 that sucks air in the bathroom 1 and four blowout ports 111 a, 111 b, 111 c, and 111 d that blow air into the bathroom 1. As shown in FIG. 2A, the housing 101 includes a peripheral wall 101a and a partition wall 101b that divides a region surrounded by the peripheral wall 101a into two regions S1 and S2.

  Moreover, the bathroom drying apparatus 100 is provided with the wind direction board (airflow adjustment part) 110a, 110b, 110c, 110d which adjusts the airflow which comes out from each blower outlet 111a, 111b, 111c, 111d, as shown in FIG.1 (b). . The wind direction plates 110a, 110b, 110c, and 110d change the direction of the airflow that exits from the air outlets 111a, 111b, 111c, and 111d by changing the inclination of the airflow direction plates, and close the air outlets 111a, 111b, 111c, and 111d. Or shut off. The wind direction plates 110a, 110b, 110c, and 110d are all substantially rectangular in plan view. The wind direction plates 110a, 110b, 110c, and 110d are supported by the wind direction plate drive motors 113a, 113b, 113c, and 113d and the support portions 114a, 114b, 114c, and 114d, respectively, at one end in the short direction and both ends in the longitudinal direction. Has been.

  The wind direction plate drive motors 113a, 113b, 113c, and 113d are composed of, for example, stepping motors. The wind direction plate drive motors 113a, 113b, 113c, and 113d rotate the wind direction plates 110a, 110b, 110c, and 110d around an axis along the longitudinal direction, thereby moving the wind direction plates 110a, 110b, 110c, and 110d with respect to the horizontal direction. Change the slope.

  The bathroom drying apparatus 100 circulates the air in the bathroom 1 and the heat exchanger 102 interposed between the regions S1 and S2 separated by the partition wall 101b in the housing 101, as shown in FIG. A circulating blower 103 to be discharged, and an exhaust blower 105 for discharging a part of the air in the bathroom 1 to the outside of the bathroom 1. And the bathroom drying apparatus 100 is provided with the control apparatus 150 which controls the above-mentioned wind direction board drive motor 113a, 113b, 113c, 113d, the air blower 103 for circulation, and the exhaust air fan 105. FIG.

  The heat exchanger 102 is blown out from the outlets 111a, 111b, 111c, and 111d when hot water (heat medium) is supplied from, for example, a hot water supply source (heat medium supply source) 5 constituted by a gas instantaneous water heater. Heat the air. As shown in FIG. 2B, the heat exchanger 102 is disposed so as to surround the periphery of the fan 103a that is disposed in a substantially central portion of the housing 101 in a plan view. The heat exchanger 102 includes a pipe through which hot water flows, and fins that increase heat exchange efficiency between the hot water flowing through the pipe and external air. As shown in FIG. 3, the heat exchanger 102 is connected to a hot water supply pipe TU1 in which a pump 164 is inserted and a drain pipe TU2. The pump 164 supplies the hot water generated by the hot water supply source 5 to the heat exchanger 102 through the hot water supply pipe TU1. The hot water that has passed through the heat exchanger 102 flows to the drain pipe TU2. The pump 164 is composed of a spiral pump including an impeller driven by, for example, a three-phase brushless motor.

The circulation blower 103 is disposed in the housing 101 and sucks air into the housing 101 from the suction port 112 and blows out the sucked air from the blowout ports 111a, 111b, 111c, and 111d, thereby allowing the air in the bathroom 1 to flow. Circulate.
As shown in FIG. 2A, the circulation fan 103 includes a fan 103a and a circulation fan motor 103b that rotates the fan 103a. The fan 103a is composed of a centrifugal fan, for example. The circulation fan motor 103b is constituted by, for example, a three-phase brushless motor. When the fan 103a rotates, the air in the bathroom 1 flows into the region S1 of the housing 101 through the suction port 112, flows into the region S2 through the heat exchanger 102, and from the blowout ports 111a, 111b, 111c, and 111d. Blown out. Thereby, as shown in FIG. 3, the air in the bathroom 1 is sucked from the bathroom 1 through the suction port 112 (see arrow D1 in FIG. 3), and the bathroom 1 is discharged from the outlets (for example, 111a and 111c). It circulates in the bathroom 1 in the form of being blown in (see arrow D2 in FIG. 3).

  The exhaust blower 105 exhausts the air in the bathroom 1 to the outdoors. Specifically, the exhaust blower 105 discharges a part of the air sucked into the housing 101 from the bathroom 1 through the suction port 112 to the outside (outdoor) of the bathroom 1. As shown in FIG. 2A, the exhaust blower 105 includes a fan 105a, an exhaust blower motor 105b that rotates the fan 105a, and a duct 105c that is an air flow path communicating with the outdoors. The fan 105a is composed of, for example, a centrifugal fan. The exhaust blower motor 105b is composed of, for example, a three-phase brushless motor. When the fan 105a rotates, the air flowing into the region S1 of the housing 101 is discharged to the outside of the bathroom 1 through the duct 105c (see arrow D4 in FIG. 3). At this time, external air flows into the bathroom 1 from the gallery 22 of the door 21 of the bathroom 1 (see arrows D31 and D32 in FIG. 3) at a flow rate substantially the same as the flow rate of the air exhausted to the outside. Mix with the air inside. In this way, the exhaust blower 105 performs quantitative ventilation of the air in the bathroom 1.

  As shown in FIG. 3, the control device 150 is connected to a wind direction plate drive motor (eg, 113a) via a signal line (eg, L21), and controls the operation of the wind direction plate drive motor. The control device 150 is connected to the circulation fan motor 103b and the exhaust fan motor 105b via signal lines L1 and L3, respectively, and controls the operations of the circulation fan motor 103b and the exhaust fan motor 105b. Furthermore, the control device 150 is connected to the pump 164 via the signal line L4 and controls the operation of the pump 164.

  As shown in FIG. 4, the control device 150 includes a first inverter circuit 153a that drives the circulation fan motor 103b, a second inverter circuit 155a that drives the exhaust fan motor 105b, and a third inverter circuit that drives the pump 164. 156a. Further, the control device 150 includes inverter drive units 153b, 155b, and 156b that drive the inverter circuits 153a, 155a, and 156a, respectively. The control device 150 further includes motor drive units 154a, 154b, 154c, and 154d that drive the wind direction plate drive motors 113a, 113b, 113c, and 113d. Further, the control device 150 is input from the control unit 151 that controls the inverter drive units 153b, 155b, and 156b and the motor drive units 154a, 154b, 154c, and 154d, the storage unit 152 that stores various types of information, and the control unit 151. A signal generation unit 157 that generates a control signal based on the control information.

  The inverter circuits 153a, 155a, and 156a are configured by a circuit using a plurality of switching elements such as an IGBT (Insulated Gate Bipolar Transistor), and output three-phase AC power.

  The inverter drive units 153b, 155b, and 156b control the AC output of the inverter circuits 153a, 155a, and 156a based on the control signal supplied from the signal generation unit 157. The inverter drive units 153b, 155b, and 156b drive the inverter circuits 153a, 155a, and 156a based on, for example, PWM (Pulse Width Modulation) control. In this case, the control signal is composed of a PWM signal.

  The motor driving units 154a, 154b, 154c, and 154d are configured to include, for example, stepping motor drivers. The motor drive units 154a, 154b, 154c, and 154d operate the wind direction plate drive motors 113a, 113b, 113c, and 113d based on the control signals supplied from the signal generation unit 157, respectively. The motor drive units 154a, 154b, 154c, and 154d independently change the inclinations of the wind direction plates 110a, 110b, 110c, and 110d, respectively. The motor driving units 154a, 154b, 154c, and 154d can be configured such that the airflow direction plates 110a, 110b, 110c, and 110d close the blowing ports 111a, 111b, 111c, and 111d. As a result, the airflow exiting from the outlets 111a, 111b, 111c, and 111d is blocked.

  For example, the control unit 151 includes a CPU (Central Processing Unit). The control unit 151 performs, for example, a bathroom drying process. Details of the bathroom drying process will be described later. In addition, the control unit 151 includes a timer 151a that measures time.

The storage unit 152 is composed of, for example, a nonvolatile memory. The storage unit 152 stores a setting information table TA in which setting information such as the first inverter driving unit 153b and the motor driving units 154a, 154b, 154c, and 154d in the bathroom drying process is registered. In the setting information table TA, for example, as shown in FIG. 5, operation mode identification information, outlet identification information, execution time, wind direction plate angle, fan rotation speed, and hot water flow rate are associated with each other. Here, the operation mode identification information is information for identifying the operation mode of the bathroom drying apparatus 100. The operation mode identification information includes “IDA” indicating ceiling drying, “IDB” indicating sidewall drying, “IDC” indicating floor drying, and “IDD” indicating mold suppression operation. The air outlet identification information is information for identifying an air outlet that emits an air flow. The balloon identification information includes "ID1" indicating the balloon 111a, "ID2" indicating the balloon 111b, "ID3" indicating the balloon 111c, "ID4" indicating the balloon 111d, balloons 111a, 111b, 111c, It is composed of “ID0” indicating all of 111d. The execution time indicates the time for performing drying by continuing to generate airflow. The fan rotation speed indicates the rotation speed of the fan 103a of the circulation fan 103. The hot water flow rate indicates the flow rate of hot water supplied to the heat exchanger 102.
As shown in FIG. 5, the hot water flow rate Q2 corresponding to “IDD” indicating the mold suppression operation is larger than the hot water flow rate Q1 corresponding to “IDA” indicating the ceiling dry drying. The higher the hot water flow rate, the higher the temperature of the airflow. Therefore, at the time of the mold suppression process, a higher temperature airflow flows in the bathroom 1 than at the time of the ceiling drying process.

  As shown in FIG. 6, the wind direction plate angle corresponds to an angle formed by a horizontal plane HL orthogonal to the vertical direction and a wind direction plate (for example, the wind direction plate 110c). The wind direction plate angle θ1 is an angle when the airflow D21 exiting from the outlet 111c flows to the ceiling CE, and is set to an angle of less than 45 °. In this case, a part of the airflow that exits from the outlet 111c flows along the ceiling CE. The wind direction plate angle θ2 is an angle when the airflow D22 that exits from the outlet 111c flows to the side wall WA. The wind direction plate angle θ3 is an angle when the airflow D23 exiting from the outlet 111c flows to the floor surface FL.

  As shown in FIG. 4, the storage unit 152 identifies target operation mode identification information DA <b> 1 indicating the operation mode that the control unit 151 is currently executing, and a target that identifies the outlet that the control unit 151 is currently generating the airflow. The outlet identification information DA2 is stored. The initial value of the target operation mode identification information DA1 is set to “IDA” indicating ceiling drying, and the initial value of the target outlet identification information DA2 is set to “ID1” indicating the outlet 111a. The storage unit 152 also stores a program for controlling the operation of the bathroom drying apparatus 100 and the like. The storage unit 152 stores a program for executing a bathroom drying process, for example.

  The signal generation unit 157 individually supplies various control signals generated based on the control information input from the control unit 151 to the inverter drive units 153b, 155b, 156b and the motor drive units 154a, 154b, 154c, 154d. . When the control information including the drive commands for the inverter circuits 153a, 155a, and 156a is input from the control unit 151, the signal generation unit 157 starts supplying control signals to the inverter drive units 153b, 155b, and 156b. On the other hand, when the control information including the stop command for the inverter circuits 153a, 155a, and 156a is input from the control unit 151, the signal generation unit 157 stops the supply of the control signal to the inverter driving units 153b, 155b, and 156b. When the control information indicating the wind direction plate angle is input, the signal generation unit 157 supplies a control signal to the motor driving units 154a, 154b, 154c, and 154d based on the wind direction plate angle.

  Next, the bathroom drying process which the bathroom drying apparatus 100 which concerns on this Embodiment performs in order to dry the bathroom 1 is demonstrated, referring FIGS. 7-12. The bathroom drying process shown in FIG. 7 is started when the user turns on the power of the bathroom drying apparatus 100, for example. Moreover, the control part 151 shall operate the exhaust fan motor 105b by outputting the control information containing the drive command of the 3rd inverter circuit 156a to the signal generation part 157 immediately after the start of a bathroom drying process. Thereby, the air in the bathroom 1 is exhausted by a certain amount by the exhaust blower 105.

  First, the bathroom drying apparatus 100 performs a ceiling drying process (first process) (step S101). As a result, a high-speed airflow flows from any one of the four outlets 111a, 111b, 111c, and 111d of the bathroom drying apparatus 100 to the ceiling CE. For example, as shown in FIG. 6, in the ceiling drying process, water droplets WD adhering to the ceiling CE are blown off by flowing a high-speed airflow through the ceiling CE. Note that whether or not the water droplets WD are blown off by the high-speed airflow depends on the size of the water droplets WD and the speed of the high-speed airflow. The speed of the high-speed airflow is set to, for example, 10 m / s based on an empirical rule of the size of the water droplet WD that can adhere to the ceiling CE when used in a general method of using the bathroom 1. The details of the ceiling drying process will be described later.

  Next, the bathroom drying apparatus 100 performs a side wall / floor surface drying process (second process) (step S102). As a result, a warmer airflow than during the ceiling drying process flows from all of the outlets 111a, 111b, 111c, and 111d of the bathroom drying apparatus 100 to the side wall WA or the floor surface FL. The details of the side wall / floor surface drying process will be described later.

  Thereafter, the bathroom drying apparatus 100 performs a mold suppression process (step S103). As a result, a high-temperature airflow flows into the bathroom 1 from all of the outlets 111a, 111b, 111c, and 111d of the bathroom drying apparatus 100 as compared with the side wall / floor surface drying process. The inside of the bathroom 1 is maintained in a low humidity state by this high temperature air flow. When a low humidity shock is given to the mold mycelium in the bathroom 1 by maintaining the interior of the bathroom 1 in a low humidity state for a certain period of time, the moisture contained in the mold mycelium itself is deprived and the mold mycelium dries out, so-called mummy state It becomes. Since at least a part of the mold mycelium can be killed, the growth of the mold mycelium is suppressed. Details of the mold suppression process will be described later.

  Next, the contents of the ceiling drying process (step S101) in FIG. 7 will be described in detail with reference to FIG.

  First, the bathroom drying apparatus 100 specifies a blow-out port that emits a high-speed airflow (step S201). Specifically, based on the content of the target outlet identification information DA2 stored in the storage unit 152, the control unit 151 includes the four outlets 111a, 111b, 111c, and 111d shown in FIG. To specify the outlet from which high-speed air current is blown. For example, when the initial value of the target outlet identification information DA2 is set to “ID1” indicating the outlet 111a, the control unit 151 first specifies the outlet 111a.

  Next, the bathroom drying apparatus 100 acquires the implementation time, the wind direction plate angle, the fan rotation speed, and the hot water flow rate indicating the period during which the high-speed air current is delivered (step S202). Specifically, the control unit 151 refers to the setting information table TA based on the contents of the target operation mode identification information DA1 and the target outlet identification information DA2 stored in the storage unit 152, so that each information To get. Assume that the contents of the target operation mode identification information DA1 and the target outlet identification information DA2 are set to “IDA” indicating ceiling drying and “ID1” indicating the outlet 111a, respectively. In this case, the control unit 151 refers to the setting information table TA shown in FIG. 5 and acquires the execution time T11, the wind direction plate angle θ1, the fan rotation speed R1, and the hot water flow rate Q10.

  Returning to FIG. 8, after executing step S202, the bathroom drying apparatus 100 opens the air direction plate of the specified air outlet and closes the air direction plates of the other air outlets (step S203). Specifically, the control unit 151 transmits the control information including the acquired wind direction plate angle and the outlet identification information of the specified outlet to the signal generation unit 157. When the control information and the outlet identification information are input, the signal generation unit 157 supplies a control signal to the motor driving unit corresponding to the outlet identification information based on the wind direction plate angle. In addition, the signal generation unit 157 supplies a control signal to another motor driving unit that does not correspond to the blowing port identification information so that the blowing port is closed by the wind direction plate.

  For example, it is assumed that the bathroom drying apparatus 100 specifies the outlet 111a. In this case, the control unit 151 transmits the control information including the wind direction plate angle θ1 and the outlet identification information ID1 to the signal generation unit 157. On the other hand, the signal generation unit 157 supplies a control signal to the motor driving unit 154a corresponding to the wind direction plate 110a based on the acquired wind direction plate angle θ1. In addition, the signal generation unit 157 supplies a control signal to the other motor driving units 154b, 154c, and 154d so that the blowing ports 111b, 111c, and 111d are closed by the wind direction plates 110b, 110c, and 110d. On the other hand, the motor drive unit 154a operates the wind direction plate drive motor 113a according to the control signal to rotate the wind direction plate 110a so that the angle of the wind direction plate 110a with respect to the horizontal direction becomes the angle θ1. The other motor drive units 154b, 154c, and 154d operate the wind direction plate drive motors 113b, 113c, and 113d according to the control signal, and the wind direction plates 110b, 110c, and 110d close the air outlets 111b, 111c, and 111d. (Closed). In this case, as shown in FIG. 9A, all airflows flowing out to the region S2 in the housing 101 are concentrated on the outlet 111a (see the two-dot chain arrow in FIG. 9A). Thereby, for example, compared with a case where all of the outlets 111a, 111b, 111c, and 111d are in the open state, the outlet area of the air flow from the region S2 in the casing 101 to the outside of the casing 101 is reduced. The speed of the airflow coming out of 111a increases. Thereby, as shown in FIG. 6, the high-speed airflow which comes out of a blower outlet (for example, 111c) flows along the ceiling CE.

  Returning to FIG. 8, after executing step S203, the bathroom drying apparatus 100 starts the circulation fan motor 103b (step S204). Specifically, the control unit 151 outputs control information including the drive command for the first inverter circuit 153a and the acquired fan rotation speed R1 to the signal generation unit 157. Then, the signal generation unit 157 starts supplying the control signal to the first inverter driving unit 153b. The first inverter drive unit 153b drives the first inverter circuit 153a by the control signal to operate the circulation fan motor 103b at the same rotational speed as the fan rotational speed R1.

  Subsequently, the bathroom drying apparatus 100 starts supplying hot water to the heat exchanger 102 (step S205). Specifically, the control unit 151 transmits control information including a drive command for the third inverter circuit 156a and the acquired hot water flow rate Q1 to the signal generation unit 157. Then, the signal generation unit 157 starts supplying the control signal to the third inverter driving unit 156b. Here, the signal generation unit 157 holds in advance correlation information indicating a correlation between the rotation speed of the impeller of the pump 164 and the flow rate of the hot water flowing through the hot water supply pipe TU1. And the signal generation part 157 produces | generates a control signal so that a warm water flow volume may become the flow volume Q1 based on the correlation information currently hold | maintained previously and the received warm water flow volume. The third inverter drive unit 156b drives the third inverter circuit 156a by the control signal, and operates the pump 164 at a rotation speed corresponding to the hot water flow rate Q1. Thereby, the flow rate of the warm water flowing through the warm water supply pipe TU1 becomes the flow rate Q1.

  Thereafter, the bathroom drying apparatus 100 turns on the timer 151a (step S206).

  Next, the bathroom drying apparatus 100 determines whether or not the execution time has elapsed (step S207). Specifically, the control unit 151 determines whether or not the execution time has elapsed based on the acquired execution time and the count value of the timer 151a. The bathroom drying apparatus 100 maintains the standby state as long as the execution time does not elapse (step S207: No). During this time, high-speed airflow continues to flow from one outlet to the ceiling CE.

  As shown in FIG. 10, in the bathroom 1, areas to which airflows from the air outlets 111a, 111b, 111c, and 111d (see solid arrows in FIG. 10) are sent are area AR1, area AR2, area AR3, and area, respectively. Assume AR4. In this case, the area AR1 is the largest, and the area AR4, the area AR2, and the area AR3 are narrowed in this order. On the other hand, in the setting information table TA shown in FIG. 5, implementation times T11, T12, T13, and T14 are set corresponding to the outlet identification information ID1, ID2, ID3, and ID4. The implementation time T11 is the longest corresponding to the size of the area AR1, area AR2, area AR3, and area AR4 corresponding to the outlets 111a, 111b, 111c, and 111d, the implementation time T14, the implementation time T12, and the implementation time. It becomes shorter in the order of T13.

  Returning to FIG. 8, if it is determined in step S207 that the execution time has elapsed (step S207: Yes), the bathroom drying apparatus 100 stops supplying hot water to the heat exchanger 102 (step S208). Specifically, the control unit 151 transmits control information including a stop command for the third inverter circuit 156a to the signal generation unit 157. Then, the signal generator 157 stops the supply of the control signal to the third inverter driver 156b. Thereby, the pump 164 is stopped by stopping the third inverter circuit 156a, and the supply of hot water to the heat exchanger 102 is stopped.

  Next, the bathroom drying apparatus 100 turns off the timer 151a (step S209). At this time, the control unit 151 resets the count value of the timer 151a to the initial value.

  Thereafter, the bathroom drying apparatus 100 determines whether or not the high-speed air current has been sent out for all the outlets (step S210). Specifically, the control unit 151 is associated with each of the outlet identification information “ID1”, “ID2”, “ID3”, and “ID4”, the initial value is “OFF”, and the high-speed air current is transmitted. In this case, an execution confirmation flag that is changed to “ON” is held. The control unit 151 changes the execution confirmation flag corresponding to the performed outlet to “ON” every time the high-speed air current is sent out for one outlet. Then, when all of the execution confirmation flags are set to “ON”, the control unit 151 determines that the high-speed airflow has been sent out for all the outlets.

  If it is determined in step S210 that there is still a blow-out port that does not perform high-speed airflow delivery (step S210: No), the bathroom drying apparatus 100 performs the process of step S201 again. For example, when the bathroom drying apparatus 100 delivers high-speed airflow from the air outlet 111a, the bathroom drying apparatus 100 next identifies one of the air outlets 111b, 111c, and 111d. In step S208, as long as it is determined that there remains a blowout port that has not performed high-speed airflow delivery, the bathroom drying apparatus 100 repeats the processing from step S201 to step S206. As a result, for example, as shown in FIGS. 9A to 9D, the outlet for sending out the high-speed airflow changes from the outlet 111a → the outlet 111b → the outlet 111c → the outlet 111d (FIG. 9). 9 (a) to (d), see the two-dot chain line arrow).

  On the other hand, when it is determined in step S208 that the high-speed airflow has been sent out for all the outlets (step S210: Yes), the bathroom drying apparatus 100 returns to the bathroom drying process. At this time, the control unit 151 changes the content of the target operation mode identification information DA1 stored in the storage unit 152 from “IDA” indicating ceiling drying to “IDB” indicating sidewall drying. In addition, the control unit 151 changes the content of the target outlet identification information DA2 to “ID0” indicating all of the wind direction plates 110a, 110b, 110c, and 110d. In addition, the control unit 151 sets all the execution confirmation flags associated with the balloon identification information “ID1”, “ID2”, “ID3”, and “ID4” to the initial value “OFF”.

  Next, the contents of the side wall / floor surface drying process (step S102) in FIG. 7 will be described in detail with reference to FIG. In this side wall / floor surface drying treatment, the floor surface is dried after performing the side wall drying.

  First, the bathroom drying apparatus 100 acquires a hot water flow rate indicating an implementation time for performing side wall drying, a wind direction plate angle, a fan rotation speed, and a flow rate of hot water supplied to the heat exchanger 102 (step S301). Specifically, the control unit 151 refers to the setting information table TA, and calculates a hot water flow rate indicating an execution time for performing sidewall drying, a wind direction plate angle, a fan rotation speed, and a flow rate of hot water supplied to the heat exchanger 102. get. At this time, the target operation mode identification information DA1 is set to “IDB” indicating sidewall drying or “IDC” indicating floor drying, and the target outlet identification information DA2 is all of the outlets 111a, 111b, 111c, and 111d. Is set to “ID0”. Therefore, in the case of the setting information table TA shown in FIG. 5, the control unit 151 refers to the setting information table TA and calculates the execution time T21 or T22, the wind direction plate angle θ2 or θ3, the fan rotation speed R2 or R3, and the hot water flow rate. get. Here, since the hot water flow rate is set to “0”, the control unit 151 maintains the pump 164 in a stopped state in the ceiling drying process.

  Next, the bathroom drying apparatus 100 adjusts the wind direction plate angle (step S302). Specifically, the control unit 151 transmits the acquired control information including the wind direction plate angle θ2 or θ3 and the outlet identification information ID0 to the signal generation unit 157. When the control information including the wind direction plate angle θ2 and the outlet identification information ID0 are input, the signal generation unit 157 supplies a control signal to all the motor drive units 154a, 154b, 154c, and 154d based on the wind direction plate angle. To do. On the other hand, the motor drive units 154a, 154b, 154c, and 154d operate the wind direction plate drive motors 113a, 113b, 113c, and 113d according to control signals, respectively. Accordingly, the angle of the wind direction plates 110a, 110b, 110c, and 110d with respect to the horizontal direction becomes the angle θ2 or the angle θ3.

  Subsequently, the bathroom drying apparatus 100 adjusts the rotational speed of the circulation fan motor 103b (step S303). Specifically, the control unit 151 transmits control information including the acquired fan rotation speed R2 or R3 to the signal generation unit 157. Then, the signal generation unit 157 changes the control signal supplied to the first inverter driving unit 153b to a control signal corresponding to the fan rotational speed R2 or R3. The first inverter driving unit 153b drives the first inverter circuit 153a with the changed control signal to operate the circulation fan motor 103b at the same rotational speed as the fan rotational speed R2 or R3. Thereby, as shown in FIG. 6, the airflow which exits from a blower outlet (for example, 111c) flows toward side wall WA or the floor surface FL (refer arrow D22 or D23 in FIG. 6).

Next, the bathroom drying apparatus 100 turns on the timer 151a (step S304).
Subsequently, the bathroom drying apparatus 100 determines whether or not the execution time T21 has elapsed (step S305). Specifically, the control unit 151 determines whether or not the execution time T21 has elapsed based on the acquired execution time T21 and the count value of the timer 151a. The bathroom drying apparatus 100 maintains the standby state as long as the execution time T21 does not elapse (step S305: No). During this time, warm airflow continues to flow from all the outlets 111a, 111b, 111c, and 111d to the ceiling CE.

  In step S305, when it is determined that the execution time T21 has passed (step S305: Yes), the bathroom drying apparatus 100 turns off the timer 151a (step S306).

  Next, the bathroom drying apparatus 100 determines whether or not floor surface drying has been performed (step S307). Specifically, an operation execution confirmation flag that is associated with each operation mode identification information and is changed to “ON” when the initial value is “OFF” and the operation is performed in each operation mode. Is held. Each time the operation in each operation mode is performed, the control unit 151 changes the operation execution confirmation flag corresponding to the performed operation mode to “ON”. And the control part 151 determines with having performed floor surface drying, when the operation execution confirmation flag matched with the operation mode identification information IDC which shows floor surface drying is set to "ON".

  If it is determined in step S307 that floor drying is not performed (step S307: No), the bathroom drying apparatus 100 sets the drying target to the floor (step S308). Specifically, the control unit 151 changes the target operation mode identification information DA1 from “IDB” indicating sidewall drying to “IDC” indicating floor drying.

  Subsequently, the bathroom drying apparatus 100 performs the process of step S301 again. Here, the contents of the target operation mode identification information DA1 and the target outlet identification information DA2 are set to “IDC” indicating floor drying and “ID0” indicating all of the wind direction plates 110a, 110b, 110c, and 110d, respectively. Yes. Therefore, in the case of the setting information table TA shown in FIG. 5, the bathroom drying apparatus 100 acquires the execution time T21, the wind direction plate angle θ3, the fan rotation speed R3, and the hot water flow rate “0”. Then, the bathroom drying apparatus 100 performs the process after step S302.

  On the other hand, if it determines with having performed the floor surface drying process in step S307 (step S307: Yes), the bathroom drying apparatus 100 will return to a bathroom drying process. At this time, the control unit 151 changes the target operation mode identification information DA1 from “IDC” indicating floor drying to “IDD” indicating mold suppression.

  Next, the contents of the mold suppression process (step S103) in FIG. 8 will be described in detail with reference to FIG. In the mold suppression treatment, the humidity in the bathroom 1 is lowered and the mold mycelium generated in the bathroom 1 is dried, so that a so-called low-humidity shock is given to the mold mycelium to suppress the growth of mold mycelia.

  First, the bathroom drying apparatus 100 acquires a hot water flow rate indicating an execution time for performing mold suppression, a wind direction plate angle, a fan rotation speed, and a flow rate of hot water supplied to the heat exchanger 102 (step S401). Specifically, the control unit 151 refers to the setting information table TA, and calculates a hot water flow rate indicating an execution time for performing mold suppression, a wind direction plate angle, a fan rotation speed, and a flow rate of hot water supplied to the heat exchanger 102. get. Here, the contents of the target operation mode identification information DA1 and the target outlet identification information DA2 are set to “IDD” indicating mold suppression and “ID0” indicating all of the wind direction plates 110a, 110b, 110c, and 110d, respectively. . Therefore, in the case of the setting information table TA shown in FIG. 5, the control unit 151 refers to the setting information table TA and acquires the execution time T31, the wind direction plate angle θ1, the fan rotational speed R1, and the flow rate Q2.

  Next, the bathroom drying apparatus 100 adjusts the wind direction plate angle (step S402). Specifically, the control unit 151 transmits the control information including the acquired wind direction plate angle θ1 and the blowout port identification information ID0 to the signal generation unit 157. When the control information including the wind direction plate angle θ1 and the outlet identification information ID0 are input, the signal generation unit 157 sends a control signal to all the motor drive units 154a, 154b, 154c, and 154d based on the wind direction plate angle θ1. Supply. On the other hand, the motor drive units 154a, 154b, 154c, and 154d operate the wind direction plate drive motors 113a, 113b, 113c, and 113d according to control signals, respectively. Thereby, the angle with respect to the horizontal direction of wind direction board 110a, 110b, 110c, 110d becomes angle (theta) 1.

  Subsequently, the bathroom drying apparatus 100 adjusts the rotational speed of the circulation fan motor 103b (step S403). Specifically, the control unit 151 transmits control information including the acquired fan rotation speed R1 to the signal generation unit 157. Then, the signal generation unit 157 changes the control signal supplied to the first inverter driving unit 153b to a control signal corresponding to the fan rotational speed R1. The first inverter drive unit 153b drives the first inverter circuit 153a with the changed control signal to operate the circulation fan motor 103b at the same rotational speed as the fan rotational speed R1.

Thereafter, the bathroom drying apparatus 100 starts supplying hot water to the heat exchanger 102 (step S404). Specifically, the control unit 151 transmits control information including a drive command for the third inverter circuit 156a and the acquired hot water flow rate Q1 to the signal generation unit 157. Then, the signal generation unit 157 starts supplying the control signal to the third inverter driving unit 156b. The signal generation unit 157 generates a control signal based on the correlation information stored in advance and the received hot water flow rate Q2 so that the hot water flow rate becomes the flow rate Q2. The third inverter driving unit 156b drives the third inverter circuit 156a by the control signal, and operates the pump 164 at a rotation speed corresponding to the hot water flow rate Q2. Thereby, the flow rate of the warm water flowing through the warm water supply pipe TU1 becomes the flow rate Q2.
The warm water flow rate Q2 is set larger than the warm water flow rate Q1 during the side wall / floor surface drying process. As a result, the temperature of the airflow sent from the region S1 through the heat exchanger 102 to the bathroom 1 from the region S2 into the bathroom 1 in the housing 101 rises compared to the side wall / floor surface drying process, and the side wall / floor surface drying is performed. The humidity in the bathroom 1 is lower than that during processing.

  Next, the bathroom drying apparatus 100 turns on the timer 151a (step S405).

  Subsequently, the bathroom drying apparatus 100 determines whether or not the execution time T31 has elapsed (step S406). Specifically, the control unit 151 determines whether or not the execution time T31 has elapsed based on the acquired execution time T31 and the count value of the timer 151a. The bathroom drying apparatus 100 maintains the standby state as long as the execution time T31 does not elapse (step S406: No). During this time, high-temperature airflow continues to flow into the bathroom 1 from all the outlets 111a, 111b, 111c, and 111d.

  By the way, it is known that the generation of mold mycelia can be suppressed by repeating the maintenance of the state in which the humidity in the bathroom 1 is low for several hours in one day with one day as one cycle. For example, if the humidity in the bathroom 1 is kept below 40% for 2 hours a day, or if the humidity in the bathroom 1 is kept below 50% for 4 hours a day, It can be suppressed (see Japanese Patent No. 4042018). Thus, when a low-humidity shock is applied to the mold mycelium for several hours a day to maintain the inside of the bathroom 1 in a low humidity state, the moisture contained in the mold mycelium itself is deprived and the mold mycelium dries out, so-called mummy state. And die. From this, the execution time T31 in the mold suppression process is, for example, 2 hours or more when the humidity in the bathroom 1 is maintained at 40% or less, and 4 hours or more when the humidity in the bathroom 1 is maintained at 50% or less. Set to

  If it is determined in step S406 that the execution time T31 has elapsed (step S406: Yes), the bathroom drying apparatus 100 stops supplying hot water to the heat exchanger 102 (step S407). Specifically, the control unit 151 transmits control information including a stop command for the third inverter circuit 156a to the signal generation unit 157. Then, the signal generator 157 stops the supply of the control signal to the third inverter driver 156b, whereby the supply of hot water to the heat exchanger 102 is stopped.

  Thereafter, the bathroom drying apparatus 100 stops the circulation fan motor 103b (step S408). Specifically, the control unit 151 outputs control information including a stop command for the first inverter circuit 153a to the signal generation unit 157. Then, the signal generation unit 157 stops the first inverter circuit 153a by stopping the supply of the control signal to the first inverter driving unit 153b. As a result, the circulation fan motor 103b stops.

  Thereafter, the bathroom drying apparatus 100 turns off the timer 151a (step S409), and then returns to the bathroom drying process. At this time, the control unit 151 resets the count value of the timer 151a to the initial value.

  As described above, the bathroom drying apparatus 100 according to the present embodiment controls the wind direction plates 110a, 110b, 110c, and 110d so that the airflow flows along the ceiling CE of the bathroom 1 during the ceiling drying process, Hot water is supplied to the heat exchanger 102. Accordingly, the ceiling CE and the upper part of the side wall WA can be quickly dried, and the time during which the ceiling CE is left at a high humidity is shortened, so that mold mycelium hardly propagates on the ceiling CE. Therefore, generation | occurrence | production of the mold mycelium in the whole bathroom 1 including side wall WA and floor surface FL can be suppressed effectively. The ceiling CE of the bathroom 1 and the upper part of the side wall WA are difficult to care for and easily become a hotbed of mold mycelium. On the other hand, if the bathroom drying apparatus 100 which concerns on this Embodiment is used, the improvement of a mold prevention effect is realizable, without producing the load of a resident's mold mycelia removal work.

  In addition, the bathroom drying apparatus 100 has airflow direction plates 110a, 110b, 110c, and 110d so that the airflow flows in the direction toward the side wall WA of the bathroom 1 or the lower side (floor surface FL) of the bathroom 1 during the side wall / floor surface drying process. And the supply of hot water to the heat exchanger 102 is stopped. Thereby, since the electric power required for supply of warm water, specifically, the electric power required for driving the pump 164 can be deleted, the power consumption of the bathroom drying apparatus 100 can be significantly suppressed.

  Fig.13 (a) is an example of the time-dependent change of the power consumption of the bathroom drying apparatus concerning the conventional comparative example. Many conventional bathroom drying apparatuses supply hot water to the heat exchanger 102 even during the bathroom / floor drying process. As a result, as shown in FIG. 13A, the power consumption during the bathroom / floor drying process (between time TI1 and time TI2) is the same as that during the ceiling drying process (between time TI1 at the beginning of operation). It changes with the electric power P1 substantially the same as the power consumption. On the other hand, in the bathroom drying apparatus 100 according to the present embodiment, as shown in FIG. 13B, during the side wall / floor drying process (between time TI1 and time TI2), the heat exchanger 102 is used. In order to stop the supply of hot water, the power consumption P2 is lower than the power consumption P1 during the ceiling drying process. Thus, by stopping the hot water supply to the heat exchanger 102, power consumption can be significantly reduced.

  Many of the conventional bathroom dryers constantly flow even when the airflow is made to flow to the floor FL (side wall / floor drying treatment) where it is difficult to shorten the drying time even if the temperature of the airflow is increased, as in the above comparative example. Hot water was supplied to the heat exchanger 102. On the other hand, in the bathroom drying apparatus 100 according to the present embodiment, the heat exchange is performed by stopping the supply of hot water to the heat exchanger 102 when an air flow is passed to the floor surface FL (side wall / floor surface drying process). The warm water is not supplied to the vessel 102 wastefully. Thereby, in the bathroom drying apparatus 100 which concerns on this Embodiment, the energy-saving can also be achieved while improving the anti-mold effect.

  Moreover, the bathroom drying apparatus 100 according to the present embodiment opens only one of the four outlets 111a, 111b, 111c, and 111d and closes the other outlets in the ceiling drying process. As a result, the substantial opening area of the outlet is reduced. Thereby, since a high-speed air current can be flowed from the open outlet to the ceiling CE, water droplets attached to the ceiling CE can be blown off. Moreover, since the convection of the air in the vicinity of the ceiling CE is promoted by flowing a high-speed air current in the vicinity of the ceiling CE, the drying speed of the ceiling CE is increased, and as a result, the time required for drying the entire bathroom 1 can be shortened.

  As shown in FIG. 10, in the bathroom 1, the areas where the airflow is sent from the outlets 111a, 111b, 111c, and 111d are area AR1, area AR2, area AR3, and area AR4, respectively. Here, the area AR1 is the largest, and the areas are narrowed in the order of the area AR4, the area AR2, and the area AR3. In this case, the portion corresponding to the area AR1 in the ceiling CE is most difficult to dry, and the portion corresponding to the area AR3, the portion corresponding to the area AR2, and the portion corresponding to the area AR4 are most easily dried.

  On the other hand, in the setting information table TA, the execution time T11 for delivering the high-speed airflow from the outlet 111a is the longest, and the execution time T14 for delivering the high-speed airflow in the order of the outlets 111d, 111b, 111c. , T12 and T13 are shortened. That is, the time distribution of the execution times T11, T12, T13, and T14 for flowing high-speed airflow to each area AR1, AR2, AR3, AR4 is set to an appropriate time according to the area of each area AR1, AR2, AR3, AR4. ing. Thereby, since the part corresponding to each area AR1, AR2, AR3, AR4 in ceiling CE can be dried reliably, generation | occurrence | production of mold mycelium in ceiling CE can be suppressed reliably. Moreover, since it is possible to suppress the flow of high-speed airflow to the portions corresponding to the areas AR1, AR2, AR3, AR4 of the ceiling CE, the time for performing the ceiling drying can be shortened, and as a result, the entire bathroom 1 is dried. The time required to do this can be shortened. This also has the advantage that unnecessary power consumption in the circulation fan 103 can be suppressed.

  By the way, the method of evaporating the water droplet adhering to a ceiling by removing the air in the bathroom 1 or reducing the humidity in the bathroom 1 is also considered. However, in the case of this method, when the water droplets become large, it takes time for the water droplets to evaporate, and it may take a long time for the water droplets to be removed.

  On the other hand, the bathroom drying apparatus 100 according to the present embodiment blows off the water droplets WD adhering to the ceiling CE by flowing a high-speed air flow along the ceiling CE as shown in FIG. 6 in the ceiling drying process. To remove. Thereby, compared with the method of evaporating and removing the water droplet WD, for example, the time required to remove the water droplet WD can be remarkably shortened. In particular, in the state where many water droplets WD are attached to the ceiling CE immediately after the bathroom drying apparatus 100 starts operating, these water droplets WD can be efficiently removed, so that the drying time can be effectively shortened.

  Moreover, in the bathroom drying apparatus 100 according to the present embodiment, in the side wall / floor drying process, by supplying warm water to the heat exchanger 102, the temperature of the airflow is increased, and the air outlets 111a, 111b, 111c, 111d. Reduces the humidity of the air blown out from. Thereby, since air with low humidity can be sent to the side wall WA or the floor surface FL, drying of the side wall WA or the floor surface FL can be promoted.

(Embodiment 2)
In the present embodiment, even in the side wall / floor surface drying process, the air flow is supplied to the side wall WA or the floor surface FL from any one of the four outlets 111a, 111b, 111c, and 111d. Different from Form 1. Further, the present embodiment is also different from the first embodiment in that information indicating on / off of the exhaust blower motor 105b is registered in the setting information table TA.

  In the present embodiment, as shown in FIG. 10, the airflows (see solid arrows in FIG. 10) sent out from the outlets 111 a, 111 b, 111 c, and 111 d are respectively in the areas AR <b> 1, AR <b> 2, AR <b> 3 in the bathroom 1. It flows to AR4.

  In the setting information table TA, for example, as shown in FIG. 14, for the operation mode identification information “IDB” and “IDC” indicating sidewall drying and floor drying, the outlet identification information “ID1”, “ID1”, “ “ID2”, “ID3”, and “ID4” are associated with each other. In the setting information table TA, information indicating ON / OFF of the exhaust fan motor 105b is registered.

In the bathroom drying process according to the present embodiment, a ceiling drying process and a mold suppression process substantially the same as those in the first embodiment are performed. And the content of the side wall / floor surface drying process is different from the content of the side wall drying process in the first embodiment.
Next, the contents of the side wall / floor surface drying process according to the present embodiment will be described in detail with reference to FIG.

  First, the bathroom drying apparatus 100 specifies a blowout port corresponding to an area to be dried (step S501). Specifically, the control unit 151 identifies the outlet from which the air current is emitted from the four outlets 111a, 111b, 111c, and 111d shown in FIG. 1A based on the content of the target outlet identification information DA2. To do. Here, as explained in the first embodiment, when the ceiling drying process is finished, the control unit 151 sets the content of the target outlet identification information DA2 to “ID1” indicating the outlet 111a. Therefore, the control unit 151 first identifies the outlet 111a.

  Next, the bathroom drying apparatus 100 acquires the execution time, the wind direction plate angle, the fan rotation speed, the hot water flow rate, and the exhaust blower on / off information (step S502). Specifically, the control unit 151 acquires each piece of information by referring to the setting information table TA based on the contents of the target operation mode identification information DA1 and the target outlet identification information DA2. Assume that the contents of the target operation mode identification information DA1 and the target outlet identification information DA2 are set to “IDB” indicating sidewall drying and “ID1” indicating the outlet 111a, respectively. In this case, the control unit 151 refers to the setting information table TA and acquires information indicating the execution time T11, the wind direction plate angle θ1, the fan rotation speed R21, the flow rate Q11, and the exhaust blower off (see FIG. 14).

Subsequently, the bathroom drying apparatus 100 performs on / off setting of the exhaust fan 105 (step S503). Specifically, the control unit 151 outputs control information including a drive command or a stop command for the second inverter circuit 155a to the signal generation unit 157. When the signal generator 157 receives the control signal including the drive command, the signal generator 157 starts supplying the control signal to the second inverter driver 155b. Then, the second inverter drive unit 155b drives the second inverter circuit 155a so that the exhaust blower motor 105b rotates at a predetermined number of rotations based on a control signal. On the other hand, when the signal generation unit 157 receives the control signal including the stop command, the signal generation unit 157 stops the supply of the control signal to the second inverter driving unit 155b. In this case, the second inverter driving unit 155b stops the second inverter circuit 155a and stops the exhaust blower motor 105b.
When the target outlet identification information DA2 is set to “ID1”, the control unit 151 outputs control information including a stop command to the signal generation unit 157. On the other hand, when the target outlet identification information DA2 is set to “ID2”, “ID3”, and “ID4”, the control unit 151 outputs control information including a drive command. In this way, as shown in FIG. 10, the control unit 151 stops the exhaust blower motor 105 b when flowing an air flow from the outlet 111 a to the area AR <b> 1. On the other hand, the control unit 151 operates the exhaust blower motor 105b when airflow is allowed to flow from the outlets 111b, 111c, and 111d to the areas AR2, AR3, and AR4.

  Thereafter, the bathroom drying apparatus 100 opens the identified outlet and closes the other outlets (step S504). Specifically, the control unit 151 transmits the control information including the acquired wind direction plate angle and the outlet identification information of the specified outlet to the signal generation unit 157. When the control information and the outlet identification information are input, the signal generation unit 157 supplies a control signal to the motor driving unit corresponding to the outlet identification information based on the wind direction plate angle. In addition, the signal generation unit 157 supplies a control signal to another motor driving unit that does not correspond to the blowing port identification information so that the blowing port is closed by the wind direction plate. For example, in the case of the bathroom 1 shown in FIG. 10, when the air flow is made to flow to the portion of the floor FL corresponding to the area AR1 where the washing place 4 is provided, only the air outlet 111a is opened and the other air outlets 111b, 111c, 111d. Is closed. Thereby, a high-speed airflow flows from the outlet 111a to the washing place 4.

  Next, after performing the processing from step S303 to step S306, the bathroom drying apparatus 100 determines whether or not drying has been performed for all areas AR1, AR2, AR3, AR4 in the bathroom 1 (step S505). ). Specifically, the control unit 151 is associated with each of the outlet identification information “ID1”, “ID2”, “ID3”, and “ID4”, the initial value is “OFF”, and the high-speed air current is transmitted. In this case, an execution confirmation flag that is changed to “ON” is held. The control unit 151 changes the execution confirmation flag corresponding to the performed outlet to “ON” each time drying is performed for one area. And the control part 151 determines with having dried all the areas AR1, AR2, AR3, AR4 in the bathroom 1, when all the implementation confirmation flags are set to "ON".

  If it is determined in step S505 that there is an area where drying is not performed (step S505: No), the bathroom drying apparatus 100 performs the process of step S501 again. Here, the bathroom drying apparatus 100 specifies the blow-out port 111b corresponding to the area AR2 next when the area AR1 is dried immediately before. As long as it is determined in step S505 that there is an area where drying is not performed, the bathroom drying apparatus 100 repeats the processing from steps S501 to S308. Thereby, drying is performed in the order of area AR1, area AR2, area AR3, area AR4, for example (see FIG. 10).

  On the other hand, if it is determined in step S505 that drying has been performed for all areas AR1, AR2, AR3, and AR4 (step S505: Yes), the bathroom drying apparatus 100 performs the processing from step S307 onward.

  As described above, in the present embodiment, also in the side wall / floor surface drying process, the airflow is supplied to the side wall WA or the floor surface FL from any one of the four outlets 111a, 111b, 111c, and 111d. The Accordingly, a relatively high speed air flow can be made to flow toward the side wall WA or the floor surface FL while reducing the number of revolutions of the circulation fan motor 103b, so that the number of revolutions of the circulation fan motor 103b is reduced. Energy saving can be achieved.

  By the way, when the exhaust blower 105 operates, an airflow (refer to arrows D31 and D32 in FIG. 3) flowing from the gallery 22 of the door 21 toward the suction port 112 of the bathroom drying apparatus 100 is generated. This airflow hinders the airflow that flows in the direction from the outlet (for example, the outlet 111a) of the bathroom drying apparatus 100 toward the door 21 (for example, the airflow that flows to the area AR1 in the bathroom 1) and may hinder the drying of the area AR1. .

  In contrast, in the present embodiment, in the side wall / floor surface drying process, when the airflow is supplied from the outlet 111a to the area AR1 in the bathroom 1, the exhaust blower 105 is stopped. As a result, an airflow flowing from the louver 22 of the door 21 toward the suction port 112 is not generated, so that the airflow flowing from the outlet 111a to the area AR1 in the bathroom 1 is not obstructed by other airflows, and the side wall WA of the area AR1. And convection near the floor surface FL is promoted. Therefore, since the side wall WA and the floor surface FL can be dried quickly, generation of mold mycelia can be suppressed.

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments.
Although the bathroom drying apparatus 100 which concerns on each embodiment demonstrated the example provided with four outlets 111a, 111b, 111c, 111d, the number of outlets is not limited to four. For example, it may be 3 or less, or 5 or more.

  In addition, the bathroom drying apparatus 100 according to each embodiment has an example in which the opening areas of the four outlets 111a, 111b, 111c, and 111d are substantially equal, and the sizes of the wind direction plates 110a, 110b, 110c, and 110d are also substantially equal. explained. However, the opening area of each of the plurality of outlets may be set to a different size based on the size of the area that is dried by the airflow blown from each outlet in the bathroom 1, for example. Moreover, the magnitude | size of the wind direction board provided in each of several outlet may be set to the magnitude | size which can close each of several outlet, for example.

  For example, as shown in FIG. 16A, the bathroom drying apparatus 200 according to this modification has a configuration including three outlets 211a, 211b, and 211c. The outlet 211a has a larger opening area than the other two outlets 211b and 211c. Air outlet plates 210a, 210b, and 210c are provided at the respective outlets 211a, 211b, and 211c. The wind direction plate 210a is a highly directional wind direction plate that imparts high directivity to the airflow exiting from the outlet 211a, and is larger than the other two wind direction plates 210b and 210c. The wind direction plates 210a, 210b, and 210c are supported by wind direction plate drive motors 213a, 213b, and 213c and support portions 214a, 214b, and 214c, respectively, at one end in the short side direction and at both ends in the longitudinal direction.

  In the bathroom drying apparatus 200, as shown in FIG. 16B, the inner side of the peripheral wall 201a of the housing 201 is communicated with the suction port 112 by the partition wall 201b and the region communicated with the air outlet (for example, 211a). It is divided into S22. Fans 103a and 105a are arranged in the area S1. The bathroom drying apparatus 200 is installed, for example, in the vicinity of the side wall of the ceiling of the bathroom 1 such that the outlet 211a faces the side wall facing the side wall.

  For example, it is assumed that the bathroom 1 includes a washing place 4 as shown in FIGS. In this case, it is preferable to install the housing 201 on the ceiling CE so that the outlet 211a having a large opening area is located on the side of the area AR1 including the washing place 4. In this case, it is preferable that the airflow direction plate 210a is provided in the blowout port 211a which emits the airflow which flows into the area (washing area) AR1 including the washing place 4 in the bathroom 1.

According to this configuration, since the number of wind direction plates, wind direction plate drive motors, and support portions can be reduced, the configuration can be simplified by reducing the number of components.
Moreover, according to this structure, the wind direction board 210a is provided in the blower outlet 211a which outputs the airflow which flows into the area (washing area) AR1 including the washing place 4 in the bathroom 1, and has high directivity to the airflow which comes out of the blower outlet 211a. It is a highly directional wind direction plate. Thereby, since airflow with high directivity can be flowed to the area AR <b> 1 including the washing place 4, drying of the washing place 4 that is easily soiled can be promoted, and generation of mold mycelium at the washing place 4 can be suppressed.

  In the first embodiment, the flow rate of the hot water supplied to the heat exchanger 102 has been described as being substantially constant in each of the ceiling drying process, the side wall / floor drying process, and the mold suppression process. You may change according to the change of humidity.

  For example, as shown in FIG. 17, a bathroom drying apparatus 300 according to this modification includes a remote controller 361 that is installed outside the bathroom 1 and controls the control device 350. The remote controller 361 includes a first temperature sensor 361 a that measures the temperature outside the bathroom outside the bathroom 1, and a humidity sensor 361 b that measures the humidity outside the bathroom outside the bathroom 1. In addition, a second temperature sensor 315 that measures the temperature of the air sucked into the housing 301 from the suction port 112 (bathroom temperature) is provided inside the housing 301.

  The control device 350 controls the inverter circuit (not shown) that rotates the impeller of the pump 164, the inverter drive unit (not shown) that drives the inverter circuit, and the signal generation unit 157 as in the first embodiment. And a control unit 351 that supplies a control signal from the signal generation unit 157 to the inverter drive unit by outputting information. Further, the control device 350 includes an AD (Analog Digital) converter 358 connected to the first temperature sensor 361a, the humidity sensor 361b, and the second temperature sensor 315 via signal lines L31, L32, and L33, respectively. The control unit 351 can acquire the temperature or humidity indicated by the signals supplied from the first temperature sensor 361a, the humidity sensor 361b, and the second temperature sensor 315 via the AD converter 358.

  Next, the contents of the mold suppression process according to this modification will be described with reference to FIG. In FIG. 18, the same processes as those in the first embodiment are denoted by the same reference numerals as those in FIG.

  After the process of step S405, the bathroom drying apparatus 300 acquires the bathroom interior temperature T1, the bathroom exterior temperature T2, and the bathroom exterior humidity M2 (step S601). Specifically, the control unit 351, via the AD converter 358, the bathroom temperature T1, the bathroom outside temperature T2, and the bathroom indicated by signals supplied from the second temperature sensor 315, the first temperature sensor 361a, and the humidity sensor 361b. The outside humidity M2 is acquired.

  Next, the bathroom drying apparatus 300 estimates the bathroom humidity M1 based on the acquired bathroom temperature T1, bathroom outside temperature T2, and bathroom outside humidity M2 (step S602). Specifically, the control unit 351 estimates the bathroom humidity M1 using an estimation formula indicating the correlation between temperature and humidity. This estimation formula is composed of, for example, a formula that represents a function in which humidity decreases monotonously with temperature.

  Subsequently, the bathroom drying apparatus 300 determines whether or not the estimated bathroom humidity M1 is higher than a preset humidity upper limit value MT (H) (whether or not M1> MT (H)). Step S603). The humidity upper limit value MT (H) is set to 40%, for example.

  If it is determined in step S603 that the bathroom humidity M1 is higher than the humidity upper limit value MT (H) (step S603: Yes), the bathroom drying apparatus 300 increases the flow rate of the hot water supplied to the heat exchanger 102. After that (step S604), the processing after step S406 is performed. Specifically, the control unit 351 transmits control information including a new hot water flow rate larger than the current state to the signal generation unit 157. Then, the signal generation unit 157 starts supplying the control signal to the third inverter driving unit 156b. The signal generation unit 157 generates a control signal based on the correlation information held in advance and the received new hot water flow rate so that the hot water flow rate becomes the new hot water flow rate. The third inverter drive unit 156b drives the third inverter circuit 156a by the control signal to operate the pump 164 at a rotation speed corresponding to the new hot water flow rate. Thereby, the flow volume of the warm water which flows through the warm water supply pipe TU1 increases.

  On the other hand, if it is determined in step S603 that the bathroom humidity M1 is lower than the humidity upper limit value MT (H) (step S603: No), the bathroom drying apparatus 300 determines that the bathroom humidity M1 is lower than the humidity lower limit value MT (L ) Or not (whether M1 <MT (L)) (step S605). The humidity lower limit value MT (L) is set to 5%, for example.

  If it is determined in step S605 that the humidity M1 in the bathroom is lower than the humidity lower limit value MT (L) (step S605: Yes), the bathroom drying apparatus 300 decreases the flow rate of the hot water supplied to the heat exchanger 102. After that (step S606), the processing after step S406 is performed. Specifically, the control unit 351 transmits control information including a new hot water flow rate less than the current state to the signal generation unit 157, and the signal generation unit 157 sends a control signal corresponding to the new hot water flow rate to the third inverter. It supplies to the drive part 156b. The third inverter drive unit 156b drives the third inverter circuit 156a by the control signal to operate the pump 164 at a rotation speed corresponding to the new hot water flow rate. Thereby, the flow volume of the warm water which flows through the warm water supply pipe TU1 decreases.

  On the other hand, when it is determined in step S605 that the bathroom humidity M1 is higher than the humidity lower limit value MT (L) (step S605: No), the bathroom drying apparatus 300 performs the processing from step S406 onward.

  According to this configuration, the flow rate of the hot water supplied to the heat exchanger 102 is adjusted according to the humidity in the bathroom 1. Thereby, for example, compared to a configuration in which the flow rate of the hot water supplied to the heat exchanger 102 is constant regardless of the humidity in the bathroom 1, the humidity in the bathroom 1 can be quickly reduced, so that mold mycelia are generated. Can be effectively suppressed.

  Moreover, according to this structure, when the humidity in the bathroom 1 becomes lower than the humidity lower limit value MT (L), the flow rate of the hot water supplied to the heat exchanger 102 is decreased. Thereby, the flow rate of the hot water supplied to the heat exchanger 102 is not maintained in an unnecessarily large state, and the rotation speed of the pump 164 can be changed at a minimum required rotation speed. Therefore, power consumption in the pump 164 can be reduced.

  In addition, although the bathroom drying apparatus 300 estimated the humidity M1 in the bathroom based on the bathroom temperature T1, the bathroom outside temperature T2, and the bathroom outside humidity M2 in the above modification, the bathroom drying apparatus is in the bathroom. The method for obtaining the humidity M1 is not limited to this. For example, a configuration may be adopted in which a humidity sensor (not shown) is provided in the bathroom 1 and the bathroom drying apparatus acquires the bathroom humidity M1 from the humidity sensor. According to this configuration, since the process of estimating the bathroom humidity M1 in the bathroom drying apparatus can be omitted, the processing load on the bathroom drying apparatus, in particular, the control unit 351 can be reduced.

  In each embodiment, an example in which hot water is not supplied to the heat exchanger 102 in the ceiling drying process has been described. However, a configuration in which hot water is supplied to the heat exchanger 102 in the ceiling drying process may be used.

  For example, in the setting information table TA shown in FIG. 5, the hot water flow rate corresponding to the operation mode identification information IDA may be set to an appropriate flow rate (for example, the flow rate Q1). Then, for example, in step S202 of the ceiling drying process illustrated in FIG. 8, the bathroom drying apparatus may start supplying hot water to the heat exchanger 102 after acquiring the hot water flow rate.

  According to this configuration, the humidity of the high-speed airflow flowing along the ceiling CE can be reduced by supplying hot water to the heat exchanger 102 in the ceiling drying process. Thereby, drying of the ceiling CE can be promoted. Moreover, the temperature of the ceiling CE rises as the temperature of the high-speed airflow flowing along the ceiling CE rises. Thereby, evaporation of the water droplet WD adhering to the ceiling CE is promoted, and the drying time of the ceiling CE can be shortened.

Further, the method of reducing the humidity of the airflow is not limited to the method described in each embodiment, and for example, a configuration in which cold water or a low-temperature refrigerant is supplied to the heat exchanger 102 may be used. In this case, the airflow is dehumidified by causing moisture in the air to condense on the surface of the heat exchanger 102.
According to this structure, since the humidity of the air sent into the bathroom 1 can be lowered and the temperature can be lowered, the bathroom can be dried without the user feeling uncomfortable especially in summer. The fluid supplied to the heat exchanger 102 is not limited to hot water, and may be a refrigerant cooled by a heat pump, for example.

  In each embodiment, the example of supplying hot water to the heat exchanger 102 has been described. However, the type of the heat medium supplied to the heat exchanger 102 is not limited to this, for example, a refrigerant such as chlorofluorocarbon. Also good.

  The hot water supply source 5 of each embodiment is not limited to a gas instantaneous water heater, and may be, for example, a hot water storage type water heater or a heat pump type water heater. The heat exchanger 102 may be configured to be connectable to any of an instantaneous gas water heater, a hot water storage type water heater, or a heat pump type water heater.

  In each embodiment, although the example which supplies the hot water produced | generated with a gas instantaneous water heater directly to the heat exchanger 102 was demonstrated, the heat transport method to the heat exchanger 102 is not limited to this. For example, supplying hot water generated by a gas instantaneous water heater or hot water generated by a hot water storage water heater and brine (secondary refrigerant) heat-exchanged via the heat exchanger to the heat exchanger 102 Thus, heat transfer to the heat exchanger 102 may be performed.

  In each embodiment, the exhaust blower 105 is disposed above the circulation blower 103 and the example in which the air sucked from the suction port 112 common to the circulation blower 103 is exhausted has been described. However, the arrangement of the exhaust blower 105 is described. Is not limited to this. For example, the exhaust fan 105 may be disposed on the side of the circulation fan 103. Alternatively, the exhaust fan 105 may be configured to suck air in the bathroom 1 from another suction port different from the suction port 112 of the circulation fan 103.

  In each embodiment, although the example which can change the inclination of wind direction board 110a, 110b, 110c, 110d was demonstrated, the structure of wind direction board 110a, 110b, 110c, 110d is not limited to this. For example, the wind direction plate provided in each of the plurality of outlets may be fixed with an inclination to flow the airflow in the direction along the ceiling CE, in the horizontal direction, or in the vertical direction. In this case, air flows in multiple directions including the direction along the ceiling CE from the plurality of outlets, so that the ceiling CE can also be dried.

  Or as shown to Fig.19 (a) and (b), the bathroom drying apparatus 400 has the surrounding wall 401a and the surrounding wall of the housing | casing 101 via the wire 417a below the blower outlet 411a of the housing | casing 401 which has the partition 401b. You may provide the grill part 410 connected with 401a. In this configuration, the direction of the airflow can be changed by changing the distance between the casing 101 and the grill portion 410.

  The grill portion 410 has, for example, a flat box shape with one surface open. A first opening 410e is provided at a position corresponding to the suction port 112 at the bottom of the grill portion 410, and second openings 410a and 410c are provided at positions corresponding to the blowing ports (for example, 411a and 411c). Lids 415a and 415b are provided in the second openings 410a and 410c. In addition, a third opening (for example, 416a, 416c) is provided on the side wall of the grill portion 410. The grill portion 410 is disposed below the housing 401. As shown in FIG. 19A, the grill 410 has a first state in which the bottom is substantially in contact with the lower end of the peripheral wall 401a of the casing 401, and the bottom is in the casing 401 as shown in FIG. And a second state separated from the lower end of the peripheral wall 401a. A wire 417 a is connected to the grill portion 410. A part of the wire 417 a is wound up by a wire winder 417 b provided on the peripheral wall 401 a of the housing 401. By adjusting the winding amount of the wire 417a by the wire winder 417b, the grill portion 410 can be in either the first state or the second state.

  As shown in FIG. 19A, it is assumed that the grill portion 410 is in the first state and the lid portions 415a and 415c are open. In this case, the air sucked from the suction port 112 through the first opening 410e (see the broken line arrow D41 in FIG. 10A) is blown out from the blowing port 411a through the second openings 410a and 410c. (See broken line arrow D42 in FIG. 10A). On the other hand, as shown in FIG. 19B, the grill portion 410 is in the second state and the lid portions 415a and 415c are closed. In this case, the air sucked from the suction port 112 through the first opening 410e (see the broken line arrow D41 in FIG. 10A) is blown out from the blowout port 411a through the third openings 416a and 416c. (See broken line arrow D43 in FIG. 10A).

  In each of the embodiments, only one of the four outlets 111a, 111b, 111c, and 111d is in an open state, and the other three are in a closed state. An example of generating has been described. However, the method for generating the high-speed airflow is not limited to this, and for example, a configuration in which the high-speed airflow is generated by increasing the rotation speed of the circulation fan motor 103b of the circulation fan 103 may be used. Or the structure which produces | generates a high-speed airflow may be used by using together the method of concentrating airflow to one blower outlet, and the method of raising the rotation speed of the fan motor 103b for circulation. Further, the number of outlets to be opened is not limited to one and may be two or three.

  In each embodiment, an example of performing floor surface drying after performing side wall drying in the side wall / floor surface drying process has been described, but the order of performing side wall drying and floor surface drying is not limited thereto. The side wall may be dried after the floor surface is dried.

  In the second embodiment, the example in which the bathroom blower stops the exhaust blower 105 when the airflow is directed toward the gallery 22 (for example, the flow is directed toward the area AR1 in FIG. 10) has been described. It is not limited to the structure which stops. For example, when the bathroom drying apparatus flows the air flow toward the gallery 22, it may be configured to perform a so-called low speed operation in which the exhaust amount of the exhaust blower 105 is set to be equal to or less than a preset exhaust amount threshold value and the exhaust is continued. Here, the exhaust amount threshold value may be determined based on the velocity of the airflow flowing toward the gallery 22. The higher the airflow speed, the higher the displacement threshold value can be set.

  According to this configuration, even when the air flow is directed toward the gallery 22, since the quantitative replacement of the air in the bathroom 1 is continuously performed, the low humidity outside the bathroom 1 is continuously taken into the bathroom 1. Can do. Therefore, since the drying in the bathroom 1 can be accelerated, generation | occurrence | production of mold mycelia can be suppressed effectively by that much.

In the first and second embodiments, the example in which the hot water is supplied to the heat exchanger 102 during the ceiling drying process has been described. However, the present invention is not limited to this. For example, the hot water supply to the heat exchanger 102 is stopped during the ceiling drying process. It may be configured to. In this case, for example, in the setting information table shown in FIG. 5, the hot water flow rate corresponding to “IDA” indicating the ceiling dry drying may be set to “0”.
According to this configuration, since the operation of the pump 164 is stopped during the ceiling drying process, the power consumption of the pump 164 can be reduced.

  Moreover, the various functions which the bathroom drying apparatus which concerns on this invention implement | achieves are realizable using a normal computer system irrespective of a dedicated system. For example, to a computer connected to a network, a program for executing the above operation is stored in a non-transitory recording medium (CD-ROM or the like) that can be read by a computer system, and the program is distributed to the computer. You may comprise the bathroom drying apparatus which performs the above-mentioned process by installing in a system.

  Further, the method for providing the program to the computer is arbitrary. For example, the program may be uploaded to a bulletin board (BBS) on a communication line and distributed to a computer via the communication line. Then, the computer activates this program and executes it like other applications under the control of the OS. Thereby, a computer functions as a bathroom drying apparatus which performs the above-mentioned processing.
