FIG. 1 is a side view showing the internal configuration of the bathroom ventilation drying heater. FIG. It is the top view seen from. Moreover, FIG. 3 is a block diagram which shows the example of installation of the bathroom ventilation drying heater of 1st Embodiment.

  1 A of bathroom ventilation drying heaters of 1st Embodiment are attached to the ceiling of the bathroom 100 with the main-body part 3A which has 2 A of circulation ventilation fans exposed the front panel 4A.

  The bathroom ventilation dryer 1A is a circulation ventilation fan 2A that sucks and blows out air, and has a circulation ventilation inlet 20A through which the air in the bathroom 100 is sucked in and a blower outlet 21A through which the heater 5 is blown and hot air is blown out. Prepare.

  In addition, the bathroom ventilation dryer 1A includes a ventilation outlet 23A that exhausts air sucked from the circulation ventilation inlet 20A by the circulation ventilation fan 2A to the outside. Furthermore, the bathroom ventilation dryer 1A includes an air path switching damper 6A that switches an air path between the air outlet 21A and the air outlet 23A.

  The circulation ventilation fan 2A includes a multiblade impeller 25A, a circulation ventilation fan motor 26A that drives the impeller 25A, and a circulation ventilation fan case 27A that forms an air passage. The impeller 25A is driven and rotated by the circulation ventilation fan motor 26A to generate a flow of air blown in the centrifugal direction from the inner side to the outer peripheral side.

  The circulation ventilation fan case 27A rectifies air blown in the centrifugal direction of the impeller 25A in a shape combining a circular portion along the outer periphery of the impeller 25A and a portion along the tangential direction of the impeller 25A. Thus, a flow of air blown out along the tangential direction of the impeller 25A is generated.

  The circulation ventilation fan 2A is configured in such a manner that the direction of the rotation shaft of the impeller 25A is along the vertical direction in a state where the bathroom ventilation dryer 1A is installed on the ceiling of the bathroom which is a predetermined installation location.

  As a result, the circulation ventilation fan case 27A forms a blowout air passage 28A through which the circulation ventilation fan 2A blows air sucked from below along the rotation axis of the impeller 25A in the tangential direction of the impeller 25A.

  The circulation ventilation fan 2A includes a circulation ventilation inlet 20A through which air is sucked on the lower surface of the circulation ventilation fan case 27A. Further, the circulation ventilation fan 2A has air heated by driving the heater 5 on the lower surface of the circulation ventilation fan case 27A or air corresponding to the temperature in the bathroom 100 by deactivating the heater 5. A blowout port 21A is provided.

  Furthermore, the circulation ventilation fan 2A includes a ventilation outlet 23A through which air is blown out to the outside on the side surface of the circulation ventilation fan case 27A.

  The circulation ventilation suction port 20A is configured by providing a circular opening called a bell mouth below the rotation axis of the impeller 25A. The air outlet 21A is configured by providing a rectangular opening having a short side along the air blowing direction of the circulation ventilation fan case 27A on the lower surface of the blowing air passage 28A.

  The blowout air passage 28A configured by the circulation ventilation fan case 27A is widened at a portion where the air outlet 21A is provided, and is narrowed at a portion where the ventilation air outlet 23A is provided. In the air outlet 21A, the long side intersecting the side along the air blowing direction by the circulation ventilation fan case 27A is matched with the length in the width direction of the main body 3A.

  The air path switching damper 6A is an example of air path opening / closing means, and is rotated between an air outlet 21A provided on the lower surface of the circulation ventilation fan case 27A and a ventilation air outlet 23A provided on a side surface of the circulation ventilation fan case 27A. A shaft 60A for opening / closing operation is provided.

  The air path switching damper 6A receives a driving force of a damper motor (not shown), rotates around the shaft 60A as a fulcrum, and opens and closes the air outlet 21A and the ventilation air outlet 23A.

  In the bathroom ventilation dryer 1A, when the position of the air path switching damper 6A is set to a circulation position where the ventilation outlet 23A is closed as shown by a solid line in FIG. 1, the outlet 21A is opened and the air is blown from the circulation ventilation inlet 20A. A circulation air passage communicating with the outlet 21A is formed.

  Further, in the bathroom ventilation drying / heating machine 1A, when the position of the air path switching damper 6A is set to a ventilation position where the air outlet 21A is closed as shown by a one-dot chain line in FIG. 1, the ventilation air outlet 23A opens, and the circulation ventilation inlet A ventilation air passage communicating from 20A to the ventilation outlet 23A is formed.

  Furthermore, in the bathroom ventilation dryer 1A, when the position of the air path switching damper 6A is a circulation ventilation position between the circulation position and the ventilation position shown by the broken line in FIG. 1, both the outlet 21A and the ventilation outlet 23A are Open and form both a circulation air channel and a ventilation air channel.

  Thus, in the bathroom ventilation drying / heating machine 1A, the single circulation ventilation fan 2A sucks the air in the bathroom 100, blows the sucked air into the bathroom 100, exhausts the sucked air to the outside, and sucks the air. An operation of blowing a part of the air into the bathroom 100 and exhausting the remaining part outside the room is performed.

  The heater 5 is an example of a heating means. In this example, a PTC heater is attached to the air outlet 21A, and a heated air outlet air passage is formed at the air outlet 21A.

  When the heater 5 is driven and energized, the heater 5 is heated to heat the air passing through the air outlet 21A, and hot air is blown out from the air outlet 21A. Here, the heater 5 has a configuration in which a large number of fins are attached to the rod-shaped heater member along the longitudinal direction, and the direction in which the fins are arranged is attached to the air outlet 21A with the direction along the longitudinal direction of the air outlet 21A. .

  Further, the width in the short direction of the air outlet 21A has such a length that the two heaters 5 are mounted side by side. In this example, the two heaters 5 are mounted side by side in the short direction of the air outlet 21A. Note that the number of heaters 5 may be set according to, for example, a power supply voltage or the like, and one heater 5 may be attached. Further, in this example, the heater 5 driven by electricity as the heating means has been described as an example, but a heater such as a heat exchanger using warm water may be used.

  The main body 3A includes a main body chassis 30A that constitutes the circulation ventilation fan case 27A and a metal case 31A that covers the main body chassis 30A. The main body chassis 30A is made of a resin material, and a circulation ventilation fan case 27A covered with a metal case 31A and a flange portion 32A protruding outward from the peripheral edge of the lower end of the main body portion 3A are integrally formed.

  The main body chassis 30A has a lower cover 33A attached to the lower surface exposed from the metal case 31A. In the circulation ventilation fan 2A, a circulation ventilation suction port 20A and an outlet 21A are provided in the lower cover 33A.

  The metal case 31A has an opening facing the ventilation outlet 23A of the circulation ventilation fan 2A, and an exhaust duct joint 34A communicating with the ventilation outlet 23A is attached to the side surface.

  As for bathroom ventilation drying heating machine 1A, front panel 4A is attached to the undersurface of body part 3A. The front panel 4A opens a lower surface facing the circulation ventilation inlet 20A of the circulation ventilation fan 2A to form an inlet grill 40A.

  Further, the front panel 4A opens a lower surface facing the air outlet 21A of the circulation ventilation fan 2A to form an air outlet grille 41A.

  The blower outlet grill 41A is configured by a rectangular opening whose length in the direction along one side of the main body 3A is increased. The air outlet grille 41A is provided with a current plate so that air is blown out along the longitudinal direction.

  The bathroom ventilation dryer 1A includes a temperature sensor 7 at the circulation ventilation inlet 20A. The temperature sensor 7 is an example of an environment grasping means, and the temperature of the bathroom 100 is detected by detecting the temperature of air sucked from the circulation ventilation suction port 20A.

<Installation example of the bathroom ventilation drying heater of the first embodiment>
Next, with reference to each figure, the example of installation of 1 A of bathroom ventilation drying heaters of 1st Embodiment is demonstrated.

  The bathroom ventilation dryer 1A is installed on the ceiling panel 101 of the bathroom 100 as shown in FIG. The ceiling panel 101 of the bathroom 100 is formed with an opening to which the main body 3A of the bathroom ventilation dryer 1A is attached. For example, in the bathroom ventilation dryer 1A, the flange 32A is fixed to the reinforcing member with a screw (not shown). Attached to the ceiling panel 101.

  The bathroom ventilation dryer / heater 1A has the front panel 4A attached to the lower surface of the main body 3A, and the inlet grill 40A and the outlet grill 41A of the front panel 4A are arranged facing the bathroom 100.

  In the bathroom ventilation dryer 1A installed on the ceiling panel 101 of the bathroom 100, the exhaust duct 102 is attached to the exhaust duct joint 34A of the main body 3A. The exhaust duct 102 is connected to an outdoor grill 102a attached to an outer wall of a building (not shown) where the bathroom 100 is installed, and the bathroom ventilation / drying heater 1A is connected to the outdoors via the exhaust duct 102.

  The bathroom 100 includes a bathtub 103 and a washing place 104. The bathtub 103 is generally rectangular, and the bathtub 103 and the washing place 104 are arranged along the short direction of the bathtub 103.

  The bathroom 100 includes a land pipe 105 that is a clothes-drying member at the top of the bathtub 103. The land pipe 105 extends along the longitudinal direction of the bathtub 103 and is attached between the opposing wall surfaces 106 a and 106 b of the bathroom 100.

  In addition, the number of the land re-pipe 105 installed in the bathroom 100 is about one or two. In this example, an example in which one land re-pipe 105 is arranged is shown. Further, the clothes drying member is not limited to a pipe-like member, and may be a string or other members as long as an object to be dried such as laundry can be dried.

  The bathroom ventilation dryer 1A is installed in the upper part of the bathtub 103 so that the longitudinal direction of the outlet grille 41A is orthogonal to the longitudinal direction of the land pipe 105. Thereby, in the bathroom ventilation dryer 1A, the air blown out from the outlet grille 41A mainly spreads in a direction orthogonal to the land pipe 105.

<Control function example of bathroom ventilation dryer / heater according to the first embodiment>
FIG. 4 is a block diagram illustrating an example of a control function of the bathroom ventilation / drying heater according to the first embodiment. The bathroom ventilation dryer 1A includes a control unit 81A configured by a CPU, a memory, and the like, a circulation ventilation fan motor 26A described in FIG. 1 and the like, a damper motor 61A that drives the air path switching damper 6A, a heater 5, The temperature sensor 7 and the operation unit 82 are connected. The operation unit 82 is an example of an operation means, and is attached to, for example, a wall surface of a bathroom changing room adjacent to the bathroom 100 by a remote control device independent of the main body of the bathroom ventilation dryer 1A.

  The control unit 81A is an example of a control unit, and executes, for example, a heating operation mode, a ventilation operation mode, a cool air operation mode, and a drying operation mode by a program stored in a memory (not shown) or the like. The bathroom ventilation dryer 1A of this example includes a preheating mode and a bathing heating mode as heating operation modes.

  These operation modes are selected by a user such as a bather operating the operation unit 82. Based on the program for executing the selected operation mode, the control unit 81A drives the circulation ventilation fan motor 26A to control the fan rotation speed of the circulation ventilation fan 2A. Further, the heater 5 is driven to control the output of the heater 5. Further, the damper motor 61A is controlled to control the opening degree of the air path switching damper 6A.

  In the bathroom ventilation dryer 1A, the amount of air blown from the outlet 21A is controlled by controlling the fan rotation speed of the circulation ventilation fan 2A. Further, by controlling the output of the heater 5, the temperature of the air blown out from the outlet 21A is controlled. Furthermore, by controlling the opening degree of the air path switching damper 6A, the air path through which air is blown out and the air volume in each air path are controlled.

  In the bathroom ventilation dryer / heater 1A, state information based on the state of the bathroom 100 in which the bathroom ventilation dryer / heater 1A is installed, the state of another room such as a bathroom changing room adjacent to the bathroom 100, the operation in the operation unit 82, and the like. Obtained by status information obtaining means. In the bathroom ventilation dryer 1A, energy consumption, in this example, the heater 5 is driven by electricity according to the acquired state information, so that the air is blown out from the outlet 21A so that power consumption is suppressed. The output of the bathroom ventilation dryer 1A, such as the air volume and the temperature of the air blown from the outlet 21A, is controlled.

  In the bathroom ventilation dryer 1A, environment grasping information that is a reference for determining the state of the bathroom 100 is acquired as state information. In the bathroom ventilation dryer 1A, in order to acquire the temperature of the bathroom 100 as environment grasping information, a temperature detection unit including a temperature sensor 7 that detects the temperature of the bathroom 100 is provided as a state information acquisition unit.

  In a bathroom ventilation dryer, the fan speed and heater output are normally set in advance according to the operation mode. In the heating operation mode, the operation is executed with the preset fan speed and heater output and detected by the temperature sensor. When the temperature of the bathroom exceeds a predetermined threshold, control such as stopping the heater operation or lowering the fan rotation speed is performed.

  However, depending on the temperature state of the bathroom 100, when the operation is performed at a preset fan rotation speed and heater output, the heating performance at the start of the operation may be excessive and the power consumption may be excessive. Thus, in the bathroom ventilation dryer / heater 1A, in the heating operation mode, the bathroom ventilation dryer / heater is based on the temperature of the bathroom 100 or the like before starting the heating operation or within a predetermined time after starting the heating operation. The output of 1A is controlled.

  In the bathroom ventilation / drying / heating machine 1A, the temperature information of the bathroom 100 detected by the temperature sensor 7 is used as reference operation information for controlling the output of the bathroom ventilation / drying / heating machine 1A in an operation start state in which a desired operation mode is started. Accordingly, the fan rotation speed of the circulation ventilation fan 2A, the output of the heater 5 and the like are set in advance.

  Further, in the bathroom ventilation dryer 1A, as the output control information in the operation state in which the desired operation mode is started and the fan rotation speed of the circulation ventilation fan 2A and the output of the heater 5 are controlled based on the reference operation information, According to the temperature information detected by the temperature sensor 7, the fan rotation speed of the circulation ventilation fan 2A, the output of the heater 5, and the like are set in advance.

  In the bathroom ventilation dryer 1A, when the heating operation mode is selected, based on the temperature information detected by the temperature sensor 7 at the start of the operation in the heating operation mode, the fan rotation speed of the circulation ventilation fan 2A is determined based on the reference operation information. The output of the heater 5 is set.

  Further, in the bathroom ventilation dryer 1A, the temperature information detected by the temperature sensor 7 during execution of the heating operation mode according to the fan rotation speed of the circulation ventilation fan 2A and the output of the heater 5 set in the reference operation information. Based on the above, the fan speed of the circulation ventilation fan 2A and the output of the heater 5 are set by the output control information.

  FIG. 5 is an explanatory diagram illustrating an example of the reference operation information. In the reference operation information 200A, season determination information 201A for determining the season is set according to the temperature information 200T detected by the temperature sensor 7, and the fan speed information 202A of the circulation ventilation fan 2A is set according to the season determination information 201A. Then, the output information 203A of the heater 5 is set.

Usually, in the winter when the temperature of the outside air is low, the temperature of the bathroom 100 before bathing is considered to be low. Therefore, if the temperature T (° C.) of the bathroom 100 detected by the temperature sensor 7 is a predetermined temperature t ₁ (° C.) set in advance, it is determined that the season is winter.

  In the preheating mode of the heating operation mode, control is performed such that the temperature in the bathroom 100 is raised to a temperature suitable for bathing in a predetermined time set in advance. In order to increase the temperature of the bathroom 100 in a predetermined time, when the temperature of the bathroom 100 is low in the winter season or the like, compared with the case where the temperature of the bathroom 100 is high, the fan rotation speed of the circulation ventilation fan 2A and the heater 5 Need to increase output.

Therefore, in the reference operation information 200A, if the temperature of the bathroom 100 is t ₁ (° C.) based on the temperature information 200T detected by the temperature sensor 7, the season determination information 201A determines that the season is the winter season. In addition, when the temperature of the bathroom 100 is t ₁ (° C.), the fan rotation speed of the circulation ventilation fan 2A is set to “high” in the fan rotation speed information 202A as a setting for increasing the temperature of the bathroom 100 in a predetermined time. And the output of the heater 5 is set to “Large” in the output information 203A.

On the other hand, if the temperature is higher in spring or autumn than in winter, the temperature of the bathroom 100 before bathing is considered higher than in winter. Therefore, if the temperature T (° C.) of the bathroom 100 detected by the temperature sensor 7 is a predetermined temperature t ₂ (t ₂ > t ₁ ) (° C.) set in advance, it is determined that the season is spring / autumn. To do.

  When the season is spring or autumn and the temperature of the bathroom 100 is higher than that of the winter, in order to increase the temperature in the bathroom 100 for a predetermined time, it is necessary to increase the fan rotation speed of the circulation ventilation fan 2A and the output of the heater 5 to the same level as the winter There is no.

Therefore, in the reference operation information 200A, if the temperature of the bathroom 100 is t ₂ (° C.) based on the temperature information 200T detected by the temperature sensor 7, the season determination information 201A determines that the season is spring / autumn. . In addition, when the temperature of the bathroom 100 is t ₂ (° C.), the fan rotation speed of the circulation ventilation fan 2A is set to “small” in the fan rotation speed information 202A as a setting for increasing the temperature of the bathroom 100 in a predetermined time. And the output of the heater 5 is set to “small” in the output information 203A.

  In the reference operation information 200A shown in FIG. 5, the temperature of the bathroom 100 that switches the fan rotation speed of the circulation ventilation fan 2A and the output of the heater 5 is set in two stages, but may be set in two or more stages. Alternatively, a threshold temperature may be set, and the rotational speed of the circulation ventilation fan 2A and the output of the heater 5 may be switched depending on the temperature relative to the threshold.

<Operation Example of Bathroom Ventilation Dryer / Heater of First Embodiment>
Next, with reference to each figure, the operation example of 1 A of bathroom ventilation drying heaters of 1st Embodiment is demonstrated.

  When the heating operation mode is selected, the bathroom ventilation / drying heater 1A, at the start of the heating operation mode, at a predetermined timing in the operation start state before or after the circulation ventilation fan motor 26A is driven. Then, the temperature of the bathroom 100 is detected. In the operation of detecting the temperature of the bathroom 100 in the operation start state in the heating operation mode, air may stay in the front panel 4A. Therefore, the air sucked from the bathroom 100 by driving the circulation ventilation fan motor 26A. The temperature of the bathroom 100 can be detected more accurately by detecting the temperature of the bathroom.

  In the heating operation mode, based on the temperature information detected by the temperature sensor 7, the fan rotation speed of the circulation ventilation fan 2A and the output of the heater 5 are set by the reference operation information 200A described in FIG. 5, and the preliminary heating mode is started. The

  In the preheating mode, the airflow switching damper 6A is set to the circulation position indicated by the solid line in FIG. 1, and the circulation ventilation fan motor 26A is driven so as to achieve the fan rotation speed set based on the reference operation information 200A, thereby the impeller 25A. And the heater 5 is energized so that the output is set based on the reference operation information 200A.

  In the bathroom ventilation dryer 1A, the air in the bathroom 100 is sucked into the circulation ventilation inlet 20A from the inlet grill 40A of the front panel 4A by rotating the impeller 25A.

  In the heating operation mode, since the air path switching damper 6A is in the circulation position, substantially the entire amount of the air in the bathroom 100 sucked from the circulation ventilation inlet 20A flows to the outlet 21A. In the heating operation mode, the air flowing through the air outlet 21A is heated by the heater 5 so that warm air is blown out from the air outlet grille 41A of the front panel 4A.

  In the heating operation mode, based on the temperature of the bathroom 100 which is temperature information detected by the temperature sensor 7 at the start of operation, in the winter season when the temperature of the outside air is low, the circulation ventilation fan is used with the fan rotation speed information 202A of the reference operation information 200A The fan speed of 2A is set to “large”, and the output of the heater 5 is set to “large” in the output information 203A.

  Thereby, in the state where the temperature of the bathroom 100 before the heating operation is low in winter or the like, the temperature in the bathroom 100 is suitable for bathing within a predetermined time set in advance in the preheating mode without insufficient heating capacity. Temperature can be increased.

  On the other hand, in the state where the temperature of the bathroom 100 before heating operation is higher than that in winter, such as in spring and autumn, the heating capacity becomes excessive if the fan rotation speed and the heater output are made equal to those in winter from the start of operation. . Therefore, in the heating operation mode, based on the temperature of the bathroom 100 that is the temperature information detected by the temperature sensor 7 at the start of operation, if the outside air temperature is higher in spring or autumn than in winter, the reference operation information 200A The fan speed of the circulation ventilation fan 2A is set to “small” by the fan speed information 202A, and the output of the heater 5 is set to “small” by the output information 203A.

  Thereby, in the state where the temperature of the bathroom 100 before the heating operation is higher than that in winter, such as in spring or autumn, the heating capacity becomes excessive by lowering the fan speed and the heater output as compared with the case in winter. However, the temperature in the bathroom 100 can be raised to a temperature suitable for bathing within a predetermined time set in advance in the preheating mode while suppressing power consumption. Therefore, when a bather enters the bathroom 100, the feeling of heat and cold is suppressed, and a comfortable bathing environment can be provided while suppressing power consumption.

  In the preheating mode, the fan rotation speed of the circulation ventilation fan 2A set in the reference operation information and the output of the heater 5 are switched by the output control information based on the temperature information detected by the temperature sensor 7. As a result, control such as increasing the output of the heater 5 when the temperature in the bathroom 100 is low and decreasing the output of the heater 5 when the temperature in the bathroom 100 is high is possible, thereby eliminating excess or deficiency of the heating capacity. Can do.

  When the heating operation mode is started and a predetermined time has elapsed, the preliminary heating mode is switched to the bathing heating mode. In the bathing heating mode, the fan speed of the circulation ventilation fan 2A and the output of the heater 5 set in the reference operation information are switched by the output control information based on the temperature information detected by the temperature sensor 7. As a result, control such as increasing the output of the heater 5 when the temperature in the bathroom 100 is low and decreasing the output of the heater 5 when the temperature in the bathroom 100 is high is possible, thereby eliminating excess or deficiency of the heating capacity. Can do. Further, in the heating operation mode, if the temperature of the bathroom 100 detected by the temperature sensor 7 becomes higher than a predetermined mode switching temperature during the execution of the preheating mode, the preheating mode is heated while bathing regardless of the passage of time. It is good also as switching to a mode. Thereby, when the temperature in the bathroom 100 is high, control such as lowering the output of the heater 5 can be performed, and power consumption can be reduced.

  As another operation mode executed in the bathroom ventilation dryer / heater 1A, in the drying operation mode, the air path switching damper 6A is set to the circulation ventilation position indicated by the broken line in FIG. 1, and the circulation ventilation fan motor 26A is driven to operate the impeller. While rotating 25A, the heater 5 is energized.

  In the bathroom ventilation dryer 1A, when the impeller 25A rotates, the air in the bathroom 100 is sucked into the circulation ventilation inlet 20A from the inlet grill 40A of the front panel 4A.

  In the drying operation mode, since the air path switching damper 6A is in the circulation ventilation position, in the blowout air path 28A, the circulation air path communicating from the circulation ventilation inlet 20A to the outlet 21A and the ventilation outlet from the circulation ventilation inlet 20A Both ventilation air paths communicating with 23A are formed.

  Thereby, a part of air RA of the bathroom 100 sucked from the circulation ventilation suction port 20A by the rotation of the impeller 25A flows to the air outlet 21A. Further, the remaining air in the bathroom 100 sucked from the circulation ventilation inlet 20A flows to the ventilation outlet 23A, passes through the exhaust duct 102, and is exhausted to the outside as the exhaust EA from the outdoor grill 102a.

  In the drying operation mode, the air flowing through the air outlet 21A is heated by the heater 5 so that the hot air HA is blown out from the air outlet grill 41A of the front panel 4A.

  As a result, in the dry operation mode, it is possible to dry the object to be dried such as clothes hung on the land pipe 105 with hot air and exhaust the air including moisture in the bathroom 100 to the outside. Drying can be promoted by ventilating air in a washroom or the like.

  Specifically, if the humidity in the bathroom 100 is less than a predetermined humidity h that is a threshold value, the amount of air flowing to the air outlet 21A is increased so that a large amount of hot air is applied to an object to be dried such as clothing. If the humidity is equal to or higher than the predetermined humidity h, an operation of decreasing the humidity in the bathroom 100 by increasing the amount of air flowing to the ventilation outlet 23A is performed. Thereby, while the humidity in the bathroom 100 can be actively lowered, it can be dried by applying warm air to an object to be dried such as clothing, and drying can be promoted.

Moreover, the remainder of the air of the bathroom 100 sucked in from the circulation ventilation inlet 20A flows to the ventilation outlet 23A and is exhausted outdoors.

  In the circulation ventilation operation mode, the air flowing through the air outlet 21A is blown out from the air outlet grill 41A of the front panel 4A according to the room temperature because the heater 5 is not driven.

  As a result, in the circulation ventilation operation mode, air is circulated in the bathroom 100 and a part of the air in the bathroom 100 is exhausted to the outside for ventilation. Drying of wall surfaces, floor surfaces, etc. can be promoted.

  In the ventilation operation mode, the air path switching damper 6A is set to the ventilation position indicated by the one-dot chain line in FIG. 1, and the heater 5 is not driven, and the circulation ventilation fan motor 26A is driven to rotate the impeller 25A.

  In the bathroom ventilation dryer 1A, the air in the bathroom 100 is sucked into the circulation ventilation inlet 20A from the inlet grill 40A of the front panel 4A by rotating the impeller 25A.

  In the ventilation operation mode, since the air path switching damper 6A is in the ventilation position, substantially the entire amount of the air in the bathroom 100 sucked from the circulation ventilation inlet 20A flows to the ventilation outlet 23A and is exhausted to the outside. Therefore, in the ventilation operation mode, steam and moisture in the bathroom 100 can be discharged to suppress dew condensation and the like, thereby suppressing the occurrence of mold.

<Operation Example of Bathroom Ventilation Dryer / Heater of Second Embodiment>
FIG. 11 is an operation explanatory view showing the flow of air in the bathroom in the bathroom ventilation dryer of the second embodiment. Next, referring to each figure, the bathroom ventilation drying of the second embodiment An operation example of the heater 1B will be described.

  When the heating operation mode is selected, the bathroom ventilation dryer 1B has the temperature sensor 7 at a predetermined timing in the operation start state before or after the circulation ventilation fan motor 26B is driven when the heating operation mode is started. Then, the temperature of the bathroom 100 is detected. In the operation of detecting the temperature of the bathroom 100 in the operation start state in the heating operation mode, air may stay in the front panel 4B. Therefore, the air sucked from the bathroom 100 by driving the circulation ventilation fan motor 26B. The temperature of the bathroom 100 can be detected more accurately by detecting the temperature of the bathroom.

  In the heating operation mode, based on the temperature information detected by the temperature sensor 7, the fan rotation speed of the circulation ventilation fan 2B and the output of the heater 5 are set by the reference operation information 200B described in FIG. 10, and the preliminary heating mode is started. The

  In the preliminary heating mode, the fan passage switching damper 6B is set to the circulation position indicated by the solid line in FIG. 6 and the stirring air passage opening / closing damper 9B is set to the closed position indicated by the solid line in FIG. The circulation ventilation fan motor 26B is driven so that the numerical value becomes the same, and the impeller 25B is rotated, and the heater 5 is energized so as to have an output set based on the reference operation information 200B.

  In the bathroom ventilation dryer 1B, the air in the bathroom 100 is sucked into the circulation ventilation inlet 20B from the inlet grill 40B of the front panel 4B by rotating the impeller 25B.

  In the heating operation mode, since the air path switching damper 6B is in the circulation position, substantially the entire amount of air in the bathroom 100 sucked from the circulation ventilation suction port 20B flows to the first air outlet 21B. In the heating operation mode, the air flowing through the first air outlet 21B is heated by the heater 5 so that warm air is blown out from the first air outlet grill 41B of the front panel 4B.

  In the heating operation mode, based on the temperature of the bathroom 100, which is temperature information detected by the temperature sensor 7 at the start of operation, in the winter season when the temperature of the outside air is low, the fan speed information 202B of the reference operation information 200B is used as the circulation ventilation fan. The fan speed of 2B is set to “large”, and the output of the heater 5 is set to “large” in the output information 203B.

  Thereby, in the state where the temperature of the bathroom 100 before the heating operation is low in winter or the like, the temperature in the bathroom 100 is suitable for bathing within a predetermined time set in advance in the preheating mode without insufficient heating capacity. Temperature can be increased.

  On the other hand, in the heating operation mode, based on the temperature of the bathroom 100 that is the temperature information detected by the temperature sensor 7 at the start of operation, if the outside air temperature is high in spring or autumn compared with winter, the reference operation information 200B The fan speed of the circulation ventilation fan 2B is set to “small” by the fan speed information 202B, and the output of the heater 5 is set to “small” by the output information 203B.

  Thereby, in the state where the temperature of the bathroom 100 before the heating operation is higher than that in winter, such as in spring or autumn, the heating capacity becomes excessive by lowering the fan speed and the heater output as compared with the case in winter. However, the temperature in the bathroom 100 can be raised to a temperature suitable for bathing within a predetermined time set in advance in the preheating mode while suppressing power consumption.

  In the heating operation mode, warm air accumulates above the bathroom 100, and the temperature in the bathroom 100 may be differently stratified on the floor surface side and the ceiling side. In order to suppress the occurrence of such stratification, the air blown from the second outlet grille 42B is used as an auxiliary air for stirring the air in the bathroom 100.

Therefore, if the outside air temperature is low in winter, when the temperature T of the bath 100 detected by the temperature sensor 7, the temperature t ₃ when set in opening information 204B of the reference driving information 200B, stirring air path opening and closing dampers 9B is set to the open position indicated by a broken line in FIG. Further, if the spring or autumn, the temperature T of the bath 100 detected by the temperature sensor 7, becomes a reference operating information 200B temperature t ₄ when configured in opening information 204B of the agitating air path opening and closing dampers 9B Open To position.

  When the stirring air passage opening / closing damper 9B is set to the open position, the air flowing through the first air outlet 21B is heated by the heater 5 so that the hot air HA is blown out from the first air outlet grill 41B of the front panel 4B. The Since the air flowing through the second air outlet 22B does not pass through the heater 5, air A corresponding to the room temperature is blown out from the second air outlet grille 42B of the front panel 4B.

  In the bathroom ventilation dryer 1B, the air A blown out from the second outlet grille 42B is the wall surface 106a of the bathroom 100 on the side where the second outlet grille 42B is provided with respect to the first outlet grille 41B. Directed to.

  The air blown out from the second blowout grille 42B has an air velocity higher than the air blown out from the first blowout grille 41B because of the arrangement and size of the first blowout port 21B and the second blowout port 22B. Is fast.

  Thus, as shown in FIG. 11, the air A blown out from the second outlet grille 42B is applied to one wall surface 106a of the bathroom 100 and flows downward along the wall surface 106a as shown by an arrow A1. . The air flowing downward along the wall surface 106a flows in the vicinity of the lower layer of the bathroom 100 mainly toward the other wall surface 106b, as indicated by an arrow A2.

  In the bathroom ventilation dryer 1B, the air RA sucked from the suction grill 40B generates a flow of circulating air in the bathroom 100, so the air flowing in the vicinity of the lower layer of the bathroom 100 toward the other wall surface 106b. Flows upward along the wall surface 106b as indicated by the arrow A3, and is sucked from the suction grill 40B.

  As described above, in the bathroom ventilation dryer / heater 1B, the high-speed air blown out from the second outlet grille 42B heads downward along the one wall surface 106a of the bathroom 100, and the vicinity of the lower layer of the bathroom 100 is moved to the other side. It is possible to generate a flow of air toward the wall surface 106b and upward along the other wall surface 106b.

  Since the air blown from the first outlet grille 41B of the bathroom ventilation dryer 1B in the heating operation mode is warm air heated by the heater 5 and the relative humidity is lowered, the second outlet grille Lighter than air blown out from 42B.

  For this reason, the air blown out from the second blower outlet grille 42B, which is heavier than the air blown out from the first blower outlet grille 41B, flows to the lower layer of the bathroom 100 and agitates the air in the entire bathroom 100. Wind flow can be generated.

  From the relationship between the arrangement and size of the first air outlet 21B and the second air outlet 22B, the amount of warm air blown out from the first air outlet grill 41B is blown out from the second air outlet grill 42B. More than air. Therefore, a sufficient amount of hot air HA blown out from the first blower outlet grill 41B by the flow of air in the bathroom 100 stirred by the air blown out from the second blower outlet grille 42B is generated in the bathroom 100. It can be circulated from the ceiling side to the floor side.

  Thereby, the warm air collected near the ceiling of the bathroom 100 can be convected to the floor surface side, and the occurrence of stratification in which the temperature in the bathroom 100 differs between the floor surface side and the ceiling side can be suppressed. . Even if the heater output is lowered, warm air can be circulated on the floor side of the bathroom 100, so that power consumption can be reduced.

  In the preliminary heating mode, the fan rotation speed of the circulation ventilation fan 2B set in the reference operation information and the output of the heater 5 are switched by the output control information based on the temperature information detected by the temperature sensor 7. As a result, control such as increasing the output of the heater 5 when the temperature in the bathroom 100 is low and decreasing the output of the heater 5 when the temperature in the bathroom 100 is high is possible, thereby eliminating excess or deficiency of the heating capacity. Can do.

  When the heating operation mode is started and a predetermined time has elapsed, the preliminary heating mode is switched to the bathing heating mode. In the bathing heating mode, the fan rotation speed of the circulation ventilation fan 2B set in the reference operation information and the output of the heater 5 are switched by the output control information based on the temperature information detected by the temperature sensor 7. As a result, control such as increasing the output of the heater 5 when the temperature in the bathroom 100 is low and decreasing the output of the heater 5 when the temperature in the bathroom 100 is high is possible, thereby eliminating excess or deficiency of the heating capacity. Can do.

  As another operation mode executed in the bathroom ventilation dryer / heater 1B, in the drying operation mode, the air path switching damper 6B is set to the circulation ventilation position shown by a broken line in FIG. 6, and the stirring air path opening / closing damper 9B is opened by a broken line. At this position, the circulation ventilation fan motor 26B is driven to rotate the impeller 25B, and the heater 5 is energized.

  In the dry operation mode, since the air path switching damper 6B is in the circulation ventilation position, a part of the air in the bathroom 100 sucked from the circulation ventilation inlet 20B by the rotation of the impeller 25B is the first outlet 21B. And flows to the second outlet 22B. Moreover, the remainder of the air of the bathroom 100 sucked from the circulation ventilation inlet 20B flows to the ventilation outlet 23B and is exhausted outdoors.

  In the drying operation mode, the air flowing through the first air outlet 21B is heated by the heater 5 so that the hot air HA is blown out from the first air outlet grill 41B of the front panel 4B.

  Further, in the drying operation mode, since the stirring air path opening / closing damper 9B opens the second air outlet 22B, air also flows through the second air outlet 22B. Since the air flowing through the second air outlet 22B does not pass through the heater 5, air A corresponding to the room temperature is blown out from the second air outlet grille 42B of the front panel 4B.

  In the bathroom ventilation dryer 1B, even in the drying operation mode, the air is blown down along the one wall surface 106a of the bathroom 100 by the high-speed air blown out from the second outlet grille 42B, and the vicinity of the lower layer of the bathroom 100 is It is possible to generate a flow of air toward the other wall surface 106b and upward along the other wall surface 106b.

  Thereby, the warm air blown out from the first outlet grille 41B is also near the object to be dried hung on the land re-pipe 105 at a position away from directly below the first outlet grille 41B, which is difficult to hit directly, An air flow can be generated.

  Therefore, in the bathroom ventilation dryer / heater 1B, the moisture of the object to be dried easily evaporates, and if the output of the heater 5 is the same as the conventional one, the drying time can be shortened, and the energy required for drying the object to be dried. Can be reduced.

  Further, if the drying time is the same as that in the prior art, the output of the heater 5 can be reduced, and the energy required for drying the object to be dried can also be reduced. In addition, since part of the air in the bathroom 100 is exhausted to the outside and is ventilated, moisture and the like can be discharged to promote drying of the object to be dried. Even in the dry operation mode, based on the temperature information detected by the temperature sensor 7, the rotation speed of the circulation ventilation fan 2B and the output of the heater 5 and the opening and closing of the agitating air path opening / closing damper 9B based on the reference operation information at the start of operation. It is good also as controlling.

Specifically, if less than the predetermined temperature t ₅ the temperature of the bath 100 detected by the temperature sensor 7 is a threshold, and agitated air path opening and closing dampers 9B in the closed position shown in solid lines in FIG. 6, the heater 5 Driven and blows warm air from the first air outlet 21B. Further, if the temperature of the bath 100 detected by the temperature sensor 7 is a temperature t ₅ above, and agitated air path opening and closing dampers 9B to the open position shown in broken lines in FIG. 6, heated by the heater 5 from the second outlet 22B Unexpected air is blown into the bathroom 100.

  As a result, if the temperature in the bathroom 100 is high, the air in the bathroom 100 can be agitated to suppress the occurrence of stratification, and the entire clothing can be dried uniformly, and the drying operation time can be shortened. To reduce power consumption.

  Further, control based on humidity information of the bathroom 100 may be performed. That is, in order to acquire the humidity of the bathroom 100 as environment grasping information as a reference for determining the state of the bathroom 100, a humidity detection unit configured by a humidity sensor or the like that detects the humidity of the bathroom 100 is used as the state information acquisition unit. Prepare. In the dry mode, based on the humidity information detected by the humidity sensor, the opening degree of the air path switching damper 6B is changed during the operation, and the air RA in the bathroom 100 sucked from the circulation ventilation suction port 20B is the first blow. The amount of air flowing to the outlet 21B and the second outlet 22B and the amount of air flowing to the ventilation outlet 23B may be adjusted. Further, the opening degree of the stirring air passage opening / closing damper 9B may be changed to adjust the amount of air flowing to the first air outlet 21B and the amount of air flowing to the second air outlet 22B.

  Specifically, if the humidity of the bathroom 100 is less than a predetermined humidity h that is a threshold, the amount of air flowing to the first air outlet 21B and the second air outlet 22B is increased. In addition, the stirring air passage opening / closing damper 9B is set to the open position, and air heated by the heater 5 is blown out from the first air outlet 21B, and air that is not heated by the heater 5 is blown out from the second air outlet 22B into the bathroom 100. Then, while agitating the air in the bathroom 100, a large amount of hot air is applied to an object to be dried such as clothing. If the humidity is equal to or higher than a predetermined humidity h, the amount of air flowing to the ventilation outlet 23A is increased. The operation of lowering the humidity in the bathroom 100 is performed. Thereby, while the humidity in the bathroom 100 can be actively lowered, it can be dried by applying warm air to an object to be dried such as clothing, and drying can be promoted. Control based on temperature information of the bathroom 100 and control based on humidity information may be combined.

  In the circulation ventilation operation mode, the bathroom ventilation dryer 1B sets the air path switching damper 6B to the circulation ventilation position indicated by the broken line in FIG. 6, the stirring air path opening / closing damper 9B to the open position indicated by the broken line, and the heater 5 is not driven. Then, the circulating ventilation fan motor 26B is driven to rotate the impeller 25B.

  In the circulation ventilation operation mode, since the air path switching damper 6B is in the circulation ventilation position, a part of the air in the bathroom 100 sucked from the circulation ventilation suction port 20B is part of the first air outlet 21B and the second air outlet 22B. It flows to. Moreover, the remainder of the air of the bathroom 100 sucked from the circulation ventilation inlet 20B flows to the ventilation outlet 23B and is exhausted outdoors.

  In the circulation ventilation operation mode, the air flowing through the first air outlet 21B is blown out from the first air outlet grill 41B of the front panel 4B according to the room temperature because the heater 5 is not driven.

  Further, even in the circulation ventilation operation mode, the stirring air passage opening / closing damper 9B opens the second air outlet 22B, so that air also flows through the second air outlet 22B. Since the air flowing through the second air outlet 22B does not pass through the heater 5, air corresponding to the room temperature is blown out from the second air outlet grill 42B of the front panel 4B.

  In the bathroom ventilation dryer 1B, even in the circulation ventilation operation mode, the air is blown down along the one wall surface 106a of the bathroom 100 by the high-speed air blown out from the second outlet grille 42B, and near the lower layer of the bathroom 100 To the other wall surface 106b, and an upward air flow can be generated along the other wall surface 106b.

  Thereby, even in the circulation ventilation operation mode, it is possible to generate a flow of air that stirs the air in the entire bathroom 100, and in the bathroom 100, the air blown from the first outlet grille 41B is directly Even in places where it is difficult to hit, an air flow can be generated.

  Therefore, the drying time of each wall surface, floor surface, etc. of the bathroom 100 can be shortened. In addition, since a part of the air in the bathroom 100 is exhausted to the outside and ventilation is performed, moisture and the like can be discharged to promote drying of each wall surface and floor surface of the bathroom 100.

  In the ventilation operation mode, the air path switching damper 6B is set to the ventilation position indicated by the one-dot chain line in FIG. 6, the stirring air path opening / closing damper 9B is set to the closed position indicated by the solid line, and the circulation ventilation fan motor 26B is driven as the heater 5 is not driven. To rotate the impeller 25B.

  In the bathroom ventilation dryer 1B, the air in the bathroom 100 is sucked into the circulation ventilation inlet 20B from the inlet grill 40B of the front panel 4B by rotating the impeller 25B.

  In the ventilation operation mode, since the air path switching damper 6B is in the ventilation position, almost the entire amount of the air in the bathroom 100 sucked from the circulation ventilation suction port 20B flows to the ventilation outlet 23B and is exhausted outdoors. Therefore, in the ventilation operation mode, steam and moisture in the bathroom 100 can be discharged to suppress dew condensation and the like, thereby suppressing the occurrence of mold.

  The bathroom ventilation dryer 1B has a 24-hour ventilation operation mode. In the 24-hour ventilation operation mode, the above-described ventilation mode is always executed with an air volume that can ventilate the air in the building where the bathroom ventilation dryer 1B is installed in a predetermined time. Therefore, in the 24-hour ventilation operation mode, indoor air can be replaced with fresh air.

The fan rotation speed of the circulation ventilation fan 2B, the output of the heater 5, and the opening / closing of the stirring air path opening / closing damper 9B may be controlled according to the energy saving rate selected by operating the mode setting button 84g.

  FIG. 15 is an explanatory diagram illustrating another example of the operation unit that configures the bathroom ventilation dryer according to the third embodiment. In the operation unit 82C described in FIG. 13, the energy saving mode setting button 84g for selecting the presence / absence of the energy saving operation and the energy saving rate is provided independently from the button for selecting the operation mode. However, in the operation unit 82D, the operation mode is set. The presence or absence of energy saving operation and the energy saving rate may be selectable by the number of times the button to be selected is pressed.

  In this example, the number of times the heating mode button 84a for selecting the heating operation mode for selecting the heating operation mode using the heater 5 and the drying mode button 84b for selecting the drying operation mode are pressed, and the presence / absence of energy saving operation and energy saving are determined.
