The heat source unit 7 heats a heat medium (for example, water) flowing through the circulation pipe 71. The heat source unit 7 circulates the heat medium between the bathroom device 1 and thereby heats the bathroom device 1. The heat source unit 7 is installed outside the bathroom (specifically, outside the house).

  As shown in FIG. 1, the bathroom device 1 includes a device main body 2, a fan 31, and a heating unit 34. The bathroom device 1 according to the present embodiment includes a circulation fan 32 and a ventilation fan 33 as the fans 31.

  The apparatus main body 2 forms an outline of the bathroom apparatus 1. The apparatus main body 2 includes a main body casing 21 and a grill plate 22. The main casing 21 opens downward (this opening is referred to as a lower opening). The grill plate 22 is attached so as to cover the lower opening of the main body casing 21.

  The grill plate 22 is attached so as to face the bathroom along the ceiling 8. The grill plate 22 is provided with an inlet 23 for taking in the air in the bathroom into the main body casing 21 and an outlet 25 for blowing out the air in the main body casing 21 into the bathroom. A filter 24 is attached to the inflow port 23.

  The circulation fan 32 takes in the air in the bathroom into the apparatus main body 2, blows out the air in the apparatus main body 2 into the bathroom, and thereby circulates the air in the bathroom. When the circulation fan 32 is driven, the air in the bathroom is taken into the device main body 2 from the inlet 23 and the air in the device main body 2 is blown out from the outlet 25.

  The heating unit 34 is provided in the apparatus main body 2. The heating unit 34 heats the air taken into the apparatus main body 2 by the circulation fan 32. The heating unit 34 of the present embodiment is a heat exchanger 35. The heat exchanger 35 is connected to the heat source unit 7 through a circulation pipe 71 and exchanges heat with air taken into the apparatus main body 2 to heat the air. The circulation of the heat medium into the heat exchanger 35 is performed by an on-off valve (hereinafter referred to as an on-off valve of the heat exchanger 35) provided in the circulation pipe 71 on the upstream side of the heat exchanger 35. Is called. As the on-off valve of the heat exchanger 35, for example, a thermal valve is used.

  The ventilation fan 33 takes in the air in the bathroom into the apparatus main body 2 and discharges the air taken into the apparatus main body 2 to the outdoors. When the ventilation fan 33 is driven, bathroom air is taken into the apparatus main body 2 from the inflow port 23, and the air taken into the apparatus main body 2 is discharged outside through the exhaust duct 6.

  The bathroom device 1 includes a control device 4. The control device 4 is configured by, for example, a microcomputer whose main component is a microprocessor. The control device 4 is configured to be able to transmit and receive signals to and from the remote controller 9 in a bidirectional manner, and controls the driving of the circulation fan 32, the ventilation fan 33, the heat source unit 7, and the like according to a command signal input from the remote controller 9. . The remote controller 9 is attached to, for example, a wall of a dressing room. As shown in FIG. 3, the control device 4 drives the circulation fan 32, the ventilation fan 33, the heat source unit 7, and the like, and determines whether or not the filter 24 needs to be cleaned. And a notification control unit 42.

  The operation control unit 41 controls driving of various valves such as the ventilation fan 33 and the circulation fan 32, the heat source unit 7, and the opening / closing valve of the heat exchanger 35. The operation control unit 41 controls the heat source unit 7, the circulation fan 32, the ventilation fan 33, the thermal valve, and the like to execute the bathroom ventilation operation, the drying operation, the heating operation, and the air blowing drying operation. The operation control unit 41 executes each operation as follows (see FIG. 1).

(Ventilation operation)
Ventilation operation ventilates the bathroom. When the ventilation operation is selected by the remote controller 9, the operation control unit 41 drives the ventilation fan 33. As a result, the bathroom device 1 takes in the air in the bathroom into the device main body 2 through the inlet 23 and discharges the air in the device main body 2 to the outside through the exhaust duct 6.

(Blow drying operation)
The blow drying operation (cool wind operation) circulates the air in the bathroom while performing the ventilation operation. When the air-drying operation is selected by the remote controller 9, the operation control unit 41 drives the ventilation fan 33 and the circulation fan 32. Thereby, the bathroom apparatus 1 takes in the air in the bathroom into the apparatus main body 2 through the inlet 23, blows out a part of the taken-in air into the bathroom as it is, and discharges the other part to the outside through the exhaust duct 6. .

(Dry operation)
In the dry operation, ventilation operation is performed while sending warm air into the bathroom. When the dry operation is selected by the remote controller 9, the operation control unit 41 opens the on-off valve of the heat exchanger 35 and drives the ventilation fan 33 and the circulation fan 32. Thereby, the bathroom apparatus 1 takes in the air in the bathroom into the apparatus main body 2 through the inlet 23, heats a part of the taken-in air by the heat exchanger 35, blows it out into the bathroom, and exhausts the other part. It is discharged outside through the duct 6. In addition, execution of drying operation is performed after a user presets operation time.

  The bathroom device 1 of the present embodiment includes a normal drying operation and an eco-drying operation as drying operations. In the normal drying operation, the drying operation is executed for the entire set time. In the eco-drying operation, the air-drying operation is performed as the main drying operation, and then the drying operation is performed as the finishing operation.

(Heating operation)
The heating operation circulates air in the bathroom while sending warm air into the bathroom. When the heating operation is selected by the remote controller 9, the operation control unit 41 opens the on-off valve of the heat exchanger 35 and drives the circulation fan 32. Thereby, the bathroom apparatus 1 takes in the air in the bathroom into the apparatus body 2 through the inflow port 23, heats the taken-in air by the heat exchanger 35, and blows it out into the bathroom.

  As shown in FIG. 3, the control device 4 of this embodiment includes a notification control unit 42. The notification control unit 42 determines whether or not the filter 24 provided at the inlet 23 of the grill plate 22 needs to be cleaned. When the notification control unit 42 determines that the filter 24 needs to be cleaned, the notification unit 91 provided in the remote controller 9 notifies that the filter 24 needs to be cleaned, as will be described later.

  The notification control unit 42 includes a timer 43, a dust index acquisition unit 44, a calculation unit 45, an integration unit 46, a threshold acquisition unit 47, and a determination unit 48. Further, the notification control unit 42 includes a memory 49. The memory 49 includes a dust index table storage unit 50, a cumulative dust amount storage unit 51, and a threshold table storage unit 52.

  The timer 43 measures the operation time of the bathroom device 1. For example, when the drying operation is executed (the drying operation is started), the timer 43 starts measuring time and continuously measures time until the stop process is performed. That is, the timer 43 measures the time from the start of operation to the stop of operation (that is, the operation time). The timer 43 outputs the measured operation time value (time value) data to the calculation unit 45.

  The calculation unit 45 multiplies the time value input from the timer 43 by the dust index input from the dust index acquisition unit 44 to calculate the estimated dust amount.

  Here, the dust index is a numerical value set by estimating the amount of dust per unit time accumulated on the filter 24. The dust index is set in accordance with the amount of ventilation to the filter 24 when the ventilation fan 33 and the circulation fan 32 are driven, and the presence or absence of heating by the heating unit 34. The larger the numerical value of the dust index, the easier it is for dust to accumulate in the filter 24.

  The dust index is determined based on the correlation between the humidity and the amount of accumulated dust. The larger the value, the lower the humidity of the air taken into the apparatus main body 2 through the filter 24. In other words, when the humidity is low, dust easily floats indoors, so it can be said that the filter 24 is in an environment where dust tends to accumulate. The dust index is stored in the dust index table stored in the dust index table storage unit 50 in association with each driving situation (see Tables 1 and 2).

  The dust index acquisition unit 44 acquires a predetermined dust index from the dust index table. The dust index acquisition unit 44 of the present embodiment acquires information on each driving situation from the driving control unit 41, and acquires a corresponding dust index based on the driving situation information. The information on the driving situation may be determined by receiving a signal transmitted from the remote controller 9 and determining the commanded driving situation.

  In the dust index table, several dust indexes associated with each driving situation are stored. Table 1 shows an example of the dust index table.

埃指数取得部４４は、表１に示すように、例えば、暖房運転が実行されると、埃指数テーブルから（埃指数）＝０．４を取得する。

As shown in Table 1, for example, when the heating operation is performed, the dust index acquisition unit 44 acquires (dust index) = 0.4 from the dust index table.

  Further, when the normal drying operation is performed as the drying operation, as shown in Table 2, the dust index acquisition unit 44 performs the time until 62.5% of the set operation time elapses (for example, the set time (In the case of 1 hour, until 37.5 minutes have passed), (Dust index) = 0.5 is acquired, and (Dust index) = 1.0 is acquired for the subsequent operation time. To do. That is, in this normal drying operation, the dust index is set larger as the operation time becomes longer.

  Further, when the eco-drying operation is executed as the drying operation, as shown in Table 2, the dust index acquisition unit 44 is (dust index) for the time to execute the main drying process (performs the air-drying operation). = 0.5 is acquired, and (Dust Index) = 1.0 is acquired for the finish drying step (performing the drying operation). That is, in this eco-drying operation, the dust index is set larger as the operation time becomes longer. The time ratio between the main drying step and the finish drying is arbitrarily determined by the user.

  The dust index acquisition unit 44 outputs the dust index data acquired from the dust index table to the calculation unit 45.

  When the dust index is input, the calculation unit 45 multiplies the time value input from the timer 43 by the dust index to calculate the dust accumulation amount. The dust accumulation amount is a value indicating the amount of dust accumulated on the filter 24 by the operation currently being performed. When the calculation unit 45 calculates the dust accumulation amount, the calculation unit 45 outputs the calculation result to the integration unit 46.

  When the dust accumulation amount data is input from the calculation unit 45, the accumulating unit 46 counts the accumulated dust amount by integrating the dust accumulation amount before the operation with the dust accumulation amount due to the running operation. The accumulated dust amount is a value obtained by accumulating the dust accumulation amount from the time when the dust is reset. The accumulating unit 46 cooperates with the accumulated dust amount storage unit 51 and accumulates the accumulated dust amount calculated during the operation to the accumulated dust amount before the operation. The accumulating unit 46 adds the dust accumulation amount calculated during the operation to the accumulated dust amount before the operation to newly calculate the accumulated dust amount, and the numerical value stored in the accumulated dust amount storage unit 51 is used as a new value. Update to accumulated dust. Note that the accumulated dust amount stored in the accumulated dust amount storage unit 51 is retained even when the bathroom apparatus 1 is turned off. When the accumulating unit 46 counts the accumulated dust amount, the accumulating unit 46 outputs the accumulated dust amount data to the determining unit 48.

  When the accumulated dust amount data is input from the integration unit 46, the determination unit 48 acquires a predetermined threshold value from the threshold acquisition unit 47, and compares the accumulated dust amount with the predetermined threshold value. The threshold acquisition unit 47 acquires a predetermined threshold from the threshold table stored in the threshold table storage unit 52. In this threshold value table, predetermined threshold values related to the notification time are stored, and a plurality of types are stored. The threshold value is a value of the accumulated dust amount that requires the filter 24 to be cleaned. Table 3 shows an example of the threshold table.

本実施形態の閾値テーブルには、報知時期として、「早め」「標準」「遅め」の３種類記憶されている。この報知時期は、ユーザーがリモコン９を操作することによって選択される。閾値取得部４７は、リモコン９によって設定された報知時期の信号を受信し、これに基づいて報知時期に対応する閾値を取得する。閾値取得部４７は、所定の閾値を取得すると判定部４８に出力する。

In the threshold value table of this embodiment, three types of “early”, “standard”, and “late” are stored as notification times. This notification time is selected by the user operating the remote controller 9. The threshold acquisition unit 47 receives the signal of the notification time set by the remote controller 9 and acquires a threshold corresponding to the notification time based on this signal. The threshold acquisition unit 47 outputs the predetermined threshold to the determination unit 48 when it acquires it.

  When data of a predetermined threshold is input from the threshold acquisition unit 47, the determination unit 48 compares the predetermined threshold with the accumulated dust amount, and if the accumulated dust amount exceeds the predetermined threshold, the filter 24 Is determined to be necessary, and a signal to that effect is output to the notification means 91.

  The notification means 91 notifies that the filter 24 needs to be cleaned. As shown in FIG. 4, the notification unit 91 of the present embodiment is provided in the remote controller 9. The informing means 91 is configured by arranging LEDs at a location labeled “filter cleaning”. When the signal indicating that the filter 24 needs to be cleaned is input from the determination unit 48, the notification unit 91 turns on the LED. Thereby, the notification means 91 notifies that the filter 24 needs to be cleaned.

  The “notification that the filter 24 needs to be cleaned” is substantially synonymous with, for example, a notification that the filter 24 is clogged, a notification that the filter 24 is to be replaced, and the like. Including. Moreover, the notification means 91 does not need to be based on the lighting of the LED, and may be notification by sound or display on a display.

  The bathroom device 1 is provided with reset means 92 for resetting the accumulated dust amount. The reset means 92 is provided on the remote controller 9 and is a button labeled “filter reset”. The reset means 92 can reset the accumulated dust amount by pressing and holding the “filter reset” button.

  As shown in FIG. 3, the reset unit 92 outputs a reset signal to the integrating unit 46. When the accumulation unit 46 receives the reset signal, the accumulation unit 46 erases the accumulated dust amount stored in the accumulated dust amount storage unit 51.

  FIG. 5 shows a flowchart for determining the cleaning timing of the filter 24 of the bathroom device 1 of the present embodiment. Hereinafter, based on a flowchart, operation | movement of the bathroom apparatus 1 is demonstrated.

  When the user operates the remote controller 9 to start driving, the control device 4 acquires a driving start command signal. The control device 4 determines whether or not the heating operation is performed (S1), and when the heating operation is performed, (dust index) = 0.4 is acquired from the dust index table (S2).

  On the other hand, if it is not the heating operation, it is determined whether or not it is a blow drying operation (S3), and if it is the blow drying operation, (dust index) = 0.5 is acquired from the dust index table (S4). .

  If it is not the ventilation drying operation, it is determined whether or not it is a ventilation operation (S5), and if it is a ventilation operation, (dust index) = 0.1 is acquired from the dust index table (S6).

  If it is not a ventilation operation, it is determined whether or not it is an eco-drying operation (S7), and if it is an eco-drying operation, it is determined whether or not it is in the finish drying process (S8). If the finish drying process is in progress, (dust index) = 1.0 is acquired from the dust index table (S9). On the other hand, when the finish drying process is not in progress, since it is the main drying process, (dust index) = 0.5 is acquired from the dust index table (S10).

  If it is not the eco-dry operation, it is determined whether or not the operation time has passed 62.5% of the set operation time (S11). When 62.5% of the set operation time has elapsed (dust index) = 0.5 is acquired from the dust index table (S12), and when it has not elapsed (dust index) = 1.0 is acquired from the dust index table (S13).

  Next, the control device 4 calculates the dust accumulation amount by multiplying the acquired dust index by the operation time measured by the timer 43 (S14). Thereafter, the control device 4 adds the newly calculated dust accumulation amount to the accumulated dust amount before operation to calculate a new accumulated dust amount, and whether the accumulated dust amount is equal to or greater than a predetermined value (threshold). It is determined whether or not (S15).

  When it is determined that the accumulated dust amount is equal to or greater than a predetermined value (threshold value), the control device 4 notifies the notification means 91 that the filter 24 needs to be cleaned (S16). When the accumulated dust amount is smaller than a predetermined value (threshold value), the process returns to the start again.

  As described above, the bathroom apparatus 1 according to the present embodiment includes the apparatus main body 2 having the inlet 23 for taking in air and the outlet 25 for blowing out the air inside, the filter 24 attached to the inlet 23, A ventilation fan 33, a circulation fan 32, and a heating unit 34 are provided. The ventilation fan 33 allows air to flow into the apparatus main body 2 through the filter 24 and exhausts the air flowing into the apparatus main body 2 to the outside. The circulation fan 32 causes air to flow into the apparatus main body 2 through the filter 24, and causes the air that has flowed into the apparatus main body 2 to blow out through the outlet 25. The heating unit 34 is provided in the apparatus main body 2 and heats the air taken into the apparatus main body 2 by the circulation fan 32. The bathroom device 1 includes a control device 4 that determines whether or not the filter 24 needs to be cleaned, and a notification unit 91. When the control unit 4 determines that the filter 24 needs to be cleaned, the notification unit 91 notifies that the filter 24 needs to be cleaned. The control device 4 includes a timer 43, a calculation unit 45, an integration unit 46, and a determination unit 48. The timer 43 measures driving time. The calculation unit 45 multiplies the time measured by the timer 43 by the dust index. The dust index is an estimated amount of dust per unit time that accumulates on the filter 24. The accumulating unit 46 accumulates the numerical values calculated by the calculating unit 45 and counts the accumulated dust amount. The determination unit 48 determines whether or not the cumulative dust amount counted by the integration unit 46 exceeds a predetermined value, and notifies the notification unit 91 when the cumulative dust amount exceeds the predetermined value. Make it. The dust index of this embodiment is set corresponding to the amount of ventilation to the filter 24 when the ventilation fan 33 and the circulation fan 32 are driven, and the presence or absence of heating by the heating unit 34.

  As described above, the bathroom apparatus 1 according to the present embodiment determines the dust index in consideration of the ventilation amount of the filter 24 that is strongly related to the amount of dust accumulated on the filter 24 and the presence or absence of heating by the heating unit 34, and uses this. Then, it is determined whether or not the filter 24 needs to be cleaned. For this reason, according to the bathroom device 1 of the present embodiment, for example, the dust accumulation amount on the filter 24 can be estimated in consideration of humidity without using a humidity sensor.

Since it is determined whether or not the filter 24 needs to be cleaned, the cleaning timing of the filter 24 can be notified with high accuracy.

  Moreover, in the bathroom device 1 of the present embodiment, the dust index is set to be larger as the operation time is longer in the drying operation in which the circulation fan 32 is driven while being heated by the heating unit 34.

  When the drying operation is continued, the interior of the bathroom is gradually dried and the humidity is lowered. According to the bathroom device 1 of the present embodiment, the dust index is changed in accordance with the decrease in the humidity in the bathroom. And the dust index can be made more accurate.

  Moreover, in the bathroom apparatus 1 of this embodiment, in the ventilation drying operation which drives the ventilation fan 33 and the circulation fan 32 in the state which the heating by the heating part 34 stopped, a dust index | exponent is set large, so that operation time is long.

If the ventilation drying operation is continued, the inside of the bathroom is gradually dried and the humidity is lowered. According to the bathroom device 1 of the present embodiment, the dust index is adjusted in accordance with the reduction of the humidity in the bathroom. The dust index can be made more accurate.

When the control unit 4 determines that the filter 24 needs to be cleaned, the notification unit 91 notifies that the filter 24 needs to be cleaned. The control device 4 includes a timer 43, a calculation unit 45, an integration unit 46, and a determination unit 48. The timer 43 measures driving time. The calculation unit 45 multiplies the time measured by the timer 43 by the dust index. The dust index is an estimated amount of dust per unit time that accumulates on the filter 24. The accumulating unit 46 accumulates the numerical values calculated by the calculating unit 45 and counts the accumulated dust amount. The determination unit 48 determines whether or not the cumulative dust amount counted by the integration unit 46 exceeds a predetermined value, and notifies the notification unit 91 when the cumulative dust amount exceeds the predetermined value. Make it. The bathroom device 1 further includes a humidity detector 54 that detects the humidity of the air in the bathroom. The dust index is set to be larger as the humidity detected by the humidity detector 54 is lower.

  For this reason, according to the bathroom apparatus 1 of this embodiment, since a dust index can be determined based on the humidity in a bathroom, a dust index can be made more accurate. As a result, according to the bathroom device 1 of the present embodiment, the cleaning timing of the filter 24 can be notified more accurately.
