Stepping motors 28 and 29 are provided at the opening edges of the outlet port 23 of the front panel 21, and links 30 and 31 are fixed to the rotation shafts of the stepping motors 28 and 29. The links 26 and 27 are connected to the links 30 and 31, and angle control of the louvers 24 and 25 is performed by adjusting the rotation angles of the stepping motors 28 and 29.

In addition to the main switch, the remote controller 20 is provided with a selection button B for executing various functions. The selection button B has a preliminary heating, bath heating, clothes drying, bathroom drying, wind blowing, ventilation, and a timer. "On", "Off", and other buttons are provided. The selection operation of the selection button B of the remote controller 20 is transmitted to the control device C, and the control device C controls the bathroom air conditioner 1 based on the transmitted selection mode. The clothing drying mode is a mode for drying clothes, and bathroom drying refers to a mode for drying a wall surface for removing water droplets attached to a ceiling surface, a side wall surface, a bottom surface, etc. of a bathroom.

That is, when the warm air or the positive wind blown out from the blowout port 8 is blown into the bathroom Br, the control device C controls the rotation angles of the stepping motors 28 and 29 so that the air blowing direction is within a narrow angle. It is narrowed, the air blowing direction is widened within a wide angle, or swings toward a certain direction.

Thus, this bathroom air conditioning apparatus 1 installs louvers 24 and 25 so that angle change is possible, and the louvers 24 and 25 are angled according to the selection operation mode of the selection button B of the remote controller 20. FIG. As it is possible to change, it is possible to perform heating without letting the bather feel cold when blowing the warm air at the time of bathing, and drying clothes such as the clothes hanging on a Londry pipe (LP) (see Fig. 9) when drying clothes. It is possible to provide a bathroom air conditioning apparatus capable of eliminating non-uniformity.

When the selection operation mode of the selection button B of the remote controller 20 is a preheating mode for warming the air in the bathroom before bathing, the fan motor 13 is turned on, and the damper 17 opens the circulation air passage side. The heater 19 is energized, and as shown in Fig. 1A, the plurality of louvers 24, 25 are inclined in an inverted " H " shape so as to narrow with respect to the direction in which air is blown.

As a result, the air warmed by the heater can be sent from the ceiling side to a distant position on the floor surface side of the shower room by increasing the wind speed, and the air in the entire bathroom can be agitated extensively to quickly warm without any unevenness.

The air blowing direction of the louvers 24 and 25 is narrowed within a narrow angle, so that the tips of the louvers 24 and 25 approach each other toward the air blowing direction and the air blowing angle is narrowed. Thereby, the pressure which blows air increases, and air reaches to a position far from the blowout port 8. In particular, when the warm air is sent out, warm air can be blown from the ceiling to the vicinity of the floor surface, so that the agitation of the air is performed in a wide range in the bathroom, and the air in the bathroom can be warmed in a short time by the preliminary heating.

In addition, when the selection operation mode of the selection button B of the remote controller 20 is a bath heating mode for warming the air in the bathroom during bathing, the fan motor 13 is turned on, and the damper 17 opens the circulation air passage side. The heater 19 is energized, and as shown in Fig. 1C, the plurality of louvers 24, 25 are inclined in a substantially "H" shape so as to widen with respect to the direction in which the air is blown, so that the air warmed by the heater Are dispersed so that they do not come in direct contact with the bather and are blown out of the outlet, preventing the bather from feeling cold.

The louvers 24 and 25 are inclined in a substantially "H" shape, and the air blowing direction is widened within a wide angle, so that the tips of the louvers 24 and 25 are separated from each other toward the air blowing direction to blow out the air. The angle is widened, whereby the direction of blowing air is dispersed so that air is sent along the wall surface of the bathroom spaced apart from the central direction of the blowout port 8. In particular, when the air is blown to a wet body such as while the body is being cleaned, the bather is likely to feel cold because the body becomes cold even by the vaporized heat of moisture even in the warmed air.

In such a case, even when the air warmed by the heater is circulated to the bathroom, the blowing range of the louvers 24 and 25 can be dispersed widely so that the air in the bathroom can be warmed without causing the bathing person to feel cold. At the same time, the air is blown in a wide range, so that warm air can be blown out over a wide range of bathrooms to warm the air in a short time.

In addition, in the bath heating mode, the louvers 24 and 25 may be the bath side only. In the bath heating mode, if the air is not closed to the bather directly, the warm air may be blown in the direction of the shower room Bb.

In addition, when the selection operation mode of the selection button B of the remote controller 20 is the clothes drying mode for drying clothes in the bathroom, the fan motor 13 is turned on, the heater 19 is energized, and the damper 17 is turned on. The damper 17 is opened at the position B, and the air is circulated in the bathroom so that a part of the air is exhausted from the exhaust port 16 to the outside, so that at least the top, bottom, left and right sides of the clothes caught in the bathroom are opened. The air blowing directions of the plurality of louvers 24, 25 are swinged to at least one of the up, down, left and right so that air is blown to either side.

As a result, air is blown to the entire clothes caught in the bathroom, and drying irregularities of the clothes are eliminated.

The air blowing direction of the louvers 24 and 25 swings, for example, at a predetermined angle (for example, ± 10 degrees) around the predetermined angle at which the louvers 24 and 25 blow air. It is the oscillating direction of blowing out in a range, and oscillating the direction which blows air in a predetermined range centering on a fixed extraction angle. This is because when the drying wind is blown only in a predetermined direction when the clothing is dried on a hanger pipe (LP) (drying pipe) on the opposite wall surface of the bathroom, the clothes hanger on the hanger, and the clothes are hanged on the hanger pipe. This is because only clothes of a predetermined position can be dried, and in some cases only a part of clothes can be dried. When sending dry air toward clothing, the air dried in a wide range can be sent by swinging louvers 24 and 25, and the drying nonuniformity of clothing is eliminated.

In addition, when the selection operation mode of the selection button B of the remote controller 20 is the airflow mode for blowing the wind in the bathroom, the fan motor 13 is turned on, and the damper 17 is at the position B in FIG. 1A. The heater 19 is turned off by turning off the circulation air passage side, and the air is blown between the plurality of louvers 24 and 25 so that air is blown to the shower room side in the bathroom.

Thereby, a cool wind is sent to a bather, and refreshing bathing becomes possible for bathing, such as a summer season. The remote controller 20 of the bathroom air conditioner includes a ventilation button for exhausting the air of the bathroom to the outside, a wind button for returning the air of the bathroom to the bathroom, and a bath for warming and returning the heater to return the air of the bathroom to the bathroom. And a button for executing various functions such as a heating button, a preheating button, and a clothes drying button, and the rotation of the motor of the bathroom air conditioning apparatus and the angle setting of the damper on the basis of the button selection of the remote controller 20; The energization of the heater is controlled.

This bathroom air conditioner 1 is a ventilation device which always performs ventilation, and it performs so that it may satisfy | fill the predetermined | prescribed ventilation frequency (for example, 0.5 times / hour) of the ventilation target area of a house, or another regular ventilation device (not shown) ), The bathroom air conditioning apparatus 1 may be configured to make up for the shortfall for satisfying the number of times of ventilation.

The air in each room is sucked from the air inlet 11, which is the inlet of the fan case, through the undercut of the door, through the insect screen of the bathroom door, and through the inlet 7 of the bathroom air conditioner. It is always discharged.

And when the auto mode button B1 is on, it is determined whether to heat regardless of whether it is bathing heating or preheating (step 2). If the auto mode button B1 is off, the ventilation operation is performed for 24 hours as it is. If heating is performed, the on / off of the current sensor 51 which detects that a current flows in the lighting of the bathroom is determined as to whether the lighting of the bathroom is on (step 3). If the current sensor 51 is in the off state, it waits until it is turned on.

When the current sensor 51 is turned on, the heater 19 is energized and the front end portions of the louvers 24 and 25 are narrowed and warm air is blown to the floor to start preheating, and the 24 hour ventilation stops in the bathroom. Or the damper motor 55 is controlled by the damper 17 so that the blowing cross-sectional area of the exhaust port 5 side may be made small (step 4).

In addition, although the bathroom air conditioner 1 stops the ventilation for 24 hours or reduces the air volume at the time of lighting of the bathroom lighting, as described in another embodiment described later, a ventilation dedicated ventilation fan for exhausting air in the bathroom and In the case of a bathroom air conditioner having a circulation fan that circulates the sucked air in the bathroom, the air in the bathroom is sucked through the ducts D2 and D3 from a ventilation device installed in the other room such as a dressing room or a toilet. If it exists, ventilation stop or air volume reduction is performed in a bathroom, but it is not necessary to stop ventilation or air volume reduction for 24 hours regarding ventilation of the whole house.

In the flowchart of Fig. 5A, when a bather enters the bathroom next, the pyroelectric sensor 54 is turned on (step 5), preheating is stopped and bath heating is started (step 6). If the pyroelectric sensor 54 is not turned on, it waits until it detects a bather. Here, if a bather does not enter a bathroom by a predetermined time, you may process so that it may move to the step 7 mentioned later.

When the bath heating is started in step 6, the heater 19 is energized and the tip ends of the louvers 24 and 25 are widened so that a warm wind is sent along the entire wall of the bathroom without direct wind. Start bathing heating. While bathing heating is maintained during bathing, other control may be entered. When bathing is complete and illumination of a bathroom turns off (step 7), bathing heating is stopped and a 24 hour ventilation resumption or restoration operation is performed (step 8).

After step 8, the humidity sensor 53 detects the humidity (step 9). If the humidity is equal to or greater than a predetermined value (for example, 60%), the flow advances to step 10 to energize the heater 19 and at the same time the louver 24, 25) Swing or open and close to blow hot air, start drying, and at the same time control the damper motor 55, and put the damper 17 in the B position to circulate air into the bathroom while circulating air to discharge a part of the circulation. The bathroom drying which starts is started (step 10). Unlike the clothes drying mode, the bathroom drying mode may allow air to be blown without energizing the heater.

Then, the humidity sensor 53 again determines the humidity in the bathroom (step 11), and when the predetermined value (for example, 60%) or less is reached, drying of the bathroom is stopped (step 12), and the auto mode is stopped (step 12). ). Since the operation is returned to the ventilation operation for 24 hours in step 8, the ventilation operation is continued for another 24 hours after the auto mode stop.

In addition, as shown in Fig. 5B, the drying process of the bathroom can be performed alone. In this case, when the control unit C of the bathroom air conditioning apparatus 1 presses the button B5 of the drying mode for drying clothes or drying the bathroom alone, the humidity sensor 53 after the start by the main switch-on. Humidity detection is performed to determine the dryness level in the bathroom. If the dryness level is equal to or greater than a predetermined value, the heater 19 is energized, and the exhaust port 16 is blocked or narrowed by the damper 17 to close the louvers 24 and 25. Swing or open and close the bathroom to dry. After this drying process, if drying level is more than predetermined value again, drying process will continue, and if it becomes below predetermined value, drying process will be complete | finished and ventilation will be restarted for 24 hours.

In the above-described embodiment, it is determined whether to perform heating (either preliminary heating or bath heating) in step 2 under auto mode, and when heating is not performed (for example, in summer bathing). In order to perform the automatic drying in advance, the process proceeds to Step 9, but even if Step 2 and Step 9 are omitted, the automatic operation is established, and there is an advantage that automatic drying of the bathroom can be performed.

6 to 8 show a flowchart of another energy saving operation of the bathroom air conditioning apparatus 1. The control device C of the bathroom air conditioner 1 of FIG. 6 is of a type without the humidity sensor 53 or the pyroelectric sensor 54.

When the main switch is turned on and the ventilation button B7 is selected for 24 hours, the ventilation operation is started for 24 hours (step 1), and the selection of the auto mode button B1 is determined (step 2). If the auto mode button B1 is on, the auto operation mode is entered. If the auto mode button B1 is off, the auto mode button B1 waits until the auto mode button B1 is on.

In the auto operation mode, the on / off of the illumination switch is discriminated (step 3). In step 3, when the light switch is turned on and the current sensor 51 is turned on, after 24 hours of stopping the ventilation of the bathroom or reducing the air volume, preheating is performed for a predetermined time (a few minutes of about 1 to 5 minutes). Then, the flow shifts to bathing heating (step 5). In this preliminary heating mode, the temperature sensor 52 detects the temperature to control the temperature of the heater 19, and the temperature of the warm air is within a predetermined temperature or a predetermined temperature range (for example, within ± 5% of the predetermined temperature). Control to maintain.

Under bath heating, temperature control of the heater 19 is performed to control the heater 19 to maintain a predetermined temperature (step 6). After step 6, the on / off determination of the illumination switch is performed (step 7). When the light switch is turned off after bathing and the current sensor 51 is turned off, the flow advances to step 8 to resume the ventilation or restore operation for 24 hours and to dry the bathroom (step 8). When the bathroom drying is finished (step 10), the operation returns to the auto operation standby state. Since this bathroom drying is the same as that of step 9-12 of FIG. 5A, the description is used.

Fig. 7 shows the flow of the treatment of the subroutine of bath heating. In this bathing heating subroutine, after the start of the subroutine, it is determined whether or not the temperature during bathing is equal to or higher than the set temperature (step SB1). If the temperature is lower than the set temperature (for example, 50 ° C), the heater 19 ) Is heated and the heater 19 is stopped when the set temperature (for example, 50 ° C) is reached (step SB2). After step SB2, it is determined whether the temperature in bathing is below a preset temperature (for example, 40 degrees C or less) (step SB3), and if bath temperature is below a preset temperature, bathing heating is restarted again (step SB4).

Fig. 7 determines the necessity of heating by checking the temperature of the air blown out of the outlet 18 to the bathroom or the air of the bathroom sucked from the inlet 7, and heating is automatically performed when the temperature is lower than the set temperature. If the temperature is higher than this, automatic operation without heating is indicated.

8 shows that the pre-heating mode is started when the auto mode switch is pressed, and the bath heating switch is switched to when the bathroom light switch is turned on. First, when the ventilation operation starts for 24 hours, it is determined whether or not it is in the auto mode (step SC1). In the case of the auto mode, the auto operation is started, and the preheating mode is stopped by stopping the ventilation for 24 hours or reducing the ventilation amount. It starts (step SC2). After the start of auto operation, the on / off of the light switch is monitored by the current sensor 51 (step SC3). When the light switch is turned on, bath heating is performed (step SC4). This bath heating (step SC5) may have described the feedback control of bath heating by FIG. 7, and is made to weaken the total amount of air blown in a bathroom, or the amount of heat generated by a heater. At that time, it is preferable that the louvers 24 and 25 face the direction other than the shower room side (for example, the bathtub side). Under bath heating, the lighting switch is monitored on / off (step SC6), and when the light switch is turned off, it is determined that the bathing is completed and the bathroom is restarted for 24 hours or the volume of ventilation is increased to dry the bathroom. (Step SC7). This bathroom drying determines the completion of a drying process with the passage of time, and it determines with the start of bathroom drying comparing a drying process time with a setting time (step SC8). When the drying treatment time reaches the set time, the bathroom drying is stopped (step SC9) to end.

Thus, in this bathroom air conditioning apparatus 1, the front end part of the louver 24, 25 in the extraction direction is narrowed (at the time of preheating), or the front end part of the louver 24, 25 in the extraction direction is expanded (at the time of bath heating). By swinging the louvers 24 and 25 within a predetermined angle around the predetermined ejection direction, heating of the bathroom before bathing (preliminary heating) or heating of the bathroom at the time of bathing (bathing heating) can be performed. . At that time, in the preliminary heating, the warm air blown out from the outlet 8 can be blown to the bottom surface of the shower room, and the air flow of the entire bathroom is increased to increase the heating efficiency of the bathroom. In addition, in bath heating, the inside of a bathroom can be warmed, preventing a direct wind from reaching the bather in a shower room.
