  The dryer 4 is provided with a louver 18 that regulates the direction in which the hot air is blown, and a louver electric motor 19 (see FIG. 4) that can be rotated forward and backward as a louver drive mechanism is linked to the louver 18 to interlock it. The hot air blowing direction by 18 can be changed in the vertical direction. When adopting a configuration in which a rotary cam type crank mechanism is interposed to reciprocate up and down within a predetermined angle range, a louver electric motor of a type that does not rotate forward and backward can be used as the louver drive mechanism.

  In FIG. 1, reference numeral 20 denotes a remote control device provided in the bathroom 1 or a dressing room (not shown). Heating operation at the time of bathing, indoor drying operation for drying in the bathroom 1, objects to be dried such as clothes Can be manually operated, such as a drying preparation operation for hanging the object on the movable drying bar 6, a drying operation for drying an object to be dried, a ventilation operation for ventilating the inside of the bathroom 1, and a wind direction setting and an operation time setting.

  FIG. 4 is a block diagram showing a drive control system for the louver, which is based on weight sensors 21 and 21 such as a load cell and a strain gauge provided between the support plate 8 and the first and second support brackets 10 and 13, respectively. The measurement result is input to the adder 22, and the weight measuring means is used to measure the weight of the object to be dried hung on the movable clothes drying bar 6 with the initial value when the object to be dried is not hung on the movable object drying bar 6. 23 is configured.

The weight measuring means 23 is connected to a first controller 24 as louver drive control means, and the louver electric motor 19 is connected to the first controller 24.
The first controller 24 includes a louver weight change width deriving means 25, a first comparison means 26, a large weight change width storage means 27, a louver dry optimum position determining means 28, a motor rotation angle command means 29, a set rotation. An angle command means 30 is provided.

At the collection position, the object to be dried is hung on the movable drying bar 6 and the object to be dried is also hung on the stationary drying bar 7, and the remote control device 20 starts the drying operation with respect to the dried object. Thus, the louver 10 is stopped for a set time (for example, 10 seconds), the warm air is sent to the material to be dried, and the operation of the louver weight variation deriving means 25 is started.
When the set time elapses, a drive output is output from the set rotation angle command means 30 to the louver electric motor 19 and the dryer 4 is stopped, and the louver 18 is driven to change the blowing direction downward and stop. Then, after stopping, the dryer 4 is driven to send warm air to the object to be dried.

This operation will be described with reference to a graph showing the change over time in the measured weight in FIG.
First, at the uppermost position L1 in the drying operation state (see FIG. 3A), for example, the louver 18 is stopped for 10 seconds, and warm air is sent to the object to be dried. In the louver weight change width deriving means 25, the weight measured by the weight measuring means 23 is plotted, for example, every 0.5 seconds, and an average value in 10 seconds is obtained and multiplied by the object to be dried. It is derived as the range of change in weight from when it is not.
The louver electric motor 19 is driven, the blowing direction of the louver 18 is changed by a set angle, and the above operation is repeated at each position, and each of L2, L3, L4, L5 and L6 (see FIG. 3 (a)). The weight change width of is derived.

  When the number of stops reaches a set number of times such as six, that is, when the louver 18 moves to the lowest position in the drying operation state, the first comparison means 26 derives the weight change width deriving means 25 for louvers. The weight change width is compared with the largest weight so far stored in the large weight change width storage means 27 together with the position information, and the larger weight is stored in the large weight change width storage means 27 together with the position information. It has become. At the first blowing position, the previous weight becomes zero (or the weight when the object to be dried is not hung), so the weight measured by the weight measuring means 23 at the first blowing position is the large weight change width. It is stored in the storage means 27 together with the position information.

  In the louver drying optimum position determining means 28, the position information of the larger weight change width that is compared and taken out by the first comparing means 28 in a state where the louver 18 is moved to the lowest position in the drying operation state, that is, The position where the weight change width is maximized is obtained, and the position in the blowing direction of the louver 18 at that time is determined as the optimum drying position.

  In the motor rotation angle command means 29, the rotation angle of the louver electric motor 19 corresponding to the optimum drying position determined by the louver drying optimum position determination means 28 is calculated, and the louver electric motor 19 is set to the rotation angle. Is stopped by driving and the louver 18 is stopped at the optimum drying position.

  After the set drying time (for example, 15 minutes) has elapsed after stopping at the optimum drying position, the set rotation angle command means 30 causes the louver 18 blowing direction to be displaced downward by the set angle. The electric motor 19 is driven and stopped by a set rotation angle, and hot air is applied to the lower side of the object to be dried than at the optimum drying position. Further, this operation is repeated until the louver 18 is displaced to the blowing position which is the lowest position in the drying operation state.

  In the above embodiment, without repeating the operation of displacing the blowing direction of the louver 18 below the set angle, the louver electric motor is stopped once after the set drying time has elapsed after stopping at the optimum drying position and drying. 19 may be configured to be driven and stopped by a set rotation angle, so that the blowing direction of the louver 18 is displaced below the set angle so that the warm air is applied to the lower side of the object to be dried than at the optimum drying position. .

  According to the above configuration, when the hot air from the dryer 4 is applied to the object to be dried, the position where the weight change width is the largest, that is, the position where the hot air effectively hits the object to be dried is the optimum position. And the drying operation for the object to be dried can be efficiently performed in a short time.

FIG. 6 is a block diagram showing a drive control system for the screen and the movable clothes drying bar. The weight of the object to be dried measured by the weight measuring means 23 is set to the dehydration rate calculating means 31 every set time (for example, 15 minutes). To be input.
The weight before the start of drying is stored in the initial weight memory 32 as an initial weight. Based on the initial weight and the weight input thereafter, the dehydration rate calculating means 31 calculates the dehydration rate W (%) based on the following equation. Is calculated.
Dehydration rate W = (1−W2 / W1) × 100
W1: Initial weight, W2: Weight of the object to be dried measured by the weight measuring means 23. The dehydration rate calculated by the dehydration rate calculating means 31 and the set dehydration rate (for example, 20%) are the second comparing means 33. The drying end determination means 34 is configured to determine that the object to be dried hung on the movable drying bar 6 has reached the drying end timing based on the calculated dehydration rate being the set dehydration rate. Has been.

  A drive control unit 35 is connected to the second comparison unit 33 of the drying end determination unit 34, and in response to the comparison output from the second comparison unit 33, that is, the completion of drying is determined, The electric motor 11 for raising and lowering the clothesline 17 is driven, the screen 15 and the movable clothes bar 6 are moved to the drying assist position (see FIG. 3B), the space in the bathroom 1 is blocked by the screen 15, and the stationary clothes bar 7 is promoted to dry the object to be dried.

In addition, a humidity sensor 36 is provided in the bathroom 1, and the humidity measured by the humidity sensor 36 is input to the humidity difference calculation means 37 every set time (for example, 15 minutes).
The humidity input to the humidity difference calculating means 37 is stored in the humidity memory 38, and each time a new humidity is input to the humidity difference calculating means 37, the previous humidity is taken out from the humidity memory 38 and subtracted. The humidity difference at the set time is calculated.
The humidity difference calculated by the humidity difference calculating means 37 is input to the third comparing means 39, and whether or not the humidity difference has become 0, that is, the dry matter hung on the movable drying bar 6 and the fixed drying bar 7 is determined. The dry operation end determination means 40 is configured to determine the dry operation end timing from the dry state.

  Drive control means 35 is connected to the third comparison means 39 of the drying operation end determination means 40, and in response to the comparison output from the third comparison means 39, that is, the end of drying is determined, the clothes raising and lowering The electric motor 11 for raising and lowering the clothesline of the mechanism 17 is driven to move the movable object drying bar 6 and the screen 15 to the collection position (see FIG. 1), and the dryer 4 is stopped, and the object to be dried hung on the movable object drying bar 6 Is easy to capture.

  The comparison output from the third comparison means 39 is input to the take-in determination means 41, and after the movable drying bar 6 and the screen 15 are moved to the collection position, the weight of the object to be dried measured by the weight measurement means 23 is obtained. Based on this, it is determined that the weight is the weight that the object to be dried is not hung on the movable drying bar 6, and in response to the fact that the object to be dried is not hung, the drive control means 35 moves it. The clothes bar 6 and the screen 15 are moved to a standby position (position accommodated in the ceiling portion 3).

Next, a series of control operations based on the above configuration will be described in sequence with reference to the flowcharts of FIGS.
(1) Drying preparation process The drying preparation button is pushed by the remote control device 20. Thereby, the movable drying bar 6 and the screen 15 stored in the standby position are lowered to the collection position where the object to be dried is easily placed and stopped. Therefore, the object to be dried is hung on the movable drying bar 6 and the fixed drying bar 7. As an operation here, the object to be dried may be hung on the stationary drying bar 7 and then the drying preparation button may be pressed to move the movable drying bar 6 to the collection position, and the object to be dried may be hung there.

(2) Drying optimum position determination step After applying the object to be dried, the drying operation button is pushed. As the drying operation button is pressed (S1), the clothes-lifting mechanism 17 is automatically driven to move the movable clothes-drying bar 6 and the screen 15 to the drying position (FIG. 3A) (S2). 18 is stopped at the uppermost position L1 in the drying operation state (S3), and the dryer 4 is operated (ON) for a set time (for example, 10 seconds) (S4).
Next, a weight change width is derived based on the weight measured by the weight measuring means 23, and is stored in the large weight change width storage means 27 as a weight change width at the uppermost position L1 (S5).
Thereafter, the dryer 4 is stopped (OFF) for a set time (for example, 10 seconds) (S6), and the louver 18 is moved from the uppermost position L1 in the drying operation state to the position L2 that is set downward by the set angle and stopped ( S7) The dryer 4 is operated (ON) for a set time (for example, 10 seconds) (S8).

Meanwhile, the weight change width is derived based on the weight measured by the weight measuring means 23, and the large weight change width previously stored in the large weight change width storage means 27 (here, the weight change at the uppermost position L1). The larger weight change width is stored in the large weight change width storage means 27 together with the position information (S9).
Thereafter, the dryer 4 is stopped (OFF) for a set time (for example, 10 seconds) (S10), moved to a position L3 where the louver 18 is set downward at a set angle, and stopped, and the operations from step S8 to step S10 are performed. The same processing is repeated for each of the positions L4, L5 and L6 (S11).
As a result of the above process, the position having the maximum weight change width is determined as the optimum drying position (S12), and the blowing direction of the louver 18 is moved to the optimum drying position and stopped (S13).

(3) Drying operation step Before the dryer 4 is operated, the weight of the object to be dried is measured by the weight measuring means 23, and the measured weight W1 is stored in the initial weight memory 32 (S14). The dryer 4 is operated (ON) (S15).
Thereafter, for example, after confirming that a set time such as 15 minutes or 20 minutes has passed (S16), the louver electric motor 19 is driven and the blowing direction of the louver 18 is changed downward by a set angle ( S17). The operations from step S16 to step S18 are repeated until the blowing direction of the louver 18 reaches the lowest position L6 in the drying operation state.

After the drying operation is started by setting the blowing direction of the louver 18 to the lowest position L6 in the drying operation state, for example, after confirming that a set time such as 10 minutes has passed (S19), the dryer 4 is set. It is stopped (OFF) for a time (for example, 10 seconds) (S20), the weight of the object to be dried is measured by the weight measuring means 23, and the measured weight W2 and the initial weight W1 stored in the initial weight memory 32 are obtained. Based on this, the dehydration rate W is calculated (S21).
It is determined whether or not the dewatering rate W exceeds the set dewatering rate WS (S22). If not, the process proceeds to step S23, the dryer 4 is operated (ON), and the process returns to step S19.

(4) Drying auxiliary operation process When the dewatering rate W exceeds the set dewatering rate WS in step S22, it is determined that the drying of the object to be dried hung on the movable drying bar 6 has been completed, and the drying lifting mechanism 17 is automatically operated. The movable drying bar 6 and the screen 15 are moved to the drying assist position [(b) in FIG. 3] (S24), the dryer 4 is operated (ON) (S25), and the temperature from the dryer 4 is increased. The wind is blocked by the screen 15, and the indoor space in the bathroom 1 is narrowed to accelerate the drying of the object to be dried hung on the stationary drying bar 7.

(5) Drying operation end step Next, for example, after confirming that a set time of 10 minutes or the like has passed (S26), the humidity is measured by the humidity sensor 36 and stored in the humidity memory 38, and the previously stored humidity Is taken out and the humidity difference between the two is calculated (S27), and it is determined whether or not the calculated humidity difference becomes 0 (S28).
If the humidity difference is not 0 in step S28, the process returns to step S26. On the other hand, if the humidity difference is 0, the process proceeds to step S29, the dryer 4 is stopped (OFF), the clothes-lifting mechanism 17 is automatically driven, and the movable clothes-drying bar 6 and the screen 15 are moved to the collection position ( Move to FIG.

(6) Taking-in process After confirming that a set time of, for example, 10 minutes has passed (S30), the moving object drying bar 6 is dried based on the weight measured by the weight measuring means 23. Is determined, i.e., whether the object to be dried has been taken in from the movable clothes bar 6 (S31).
If the material to be dried has not been taken in at step S31, the process returns to step S30. On the other hand, if the to-be-dried object is taken in, it will transfer to step S32, for example, after confirming that setting time, such as 10 minutes, has passed, it will transfer to step S33, and the clothes raising / lowering mechanism 17 will be automatic. Driven to move the movable clothes bar 6 and the screen 15 to the standby position.
Thereby, the movable clothes bar 6 and the screen 15 are accommodated in the ceiling part 3, and a series of control operations are completed.

FIG. 10 is a block diagram showing a drive control system for the movable clothes drying bar in the bathroom drying system according to the second embodiment of the present invention, and the weight measuring means 23 is connected to the second controller 51 as the clothes drying bar drive control means. The clothes lift elevating electric motor 19 is connected to the second controller 51.
The second controller 51 includes clothes bar weight change width deriving means 52, fourth comparison means 53, large weight change width storage means 54, clothes bar dry optimum position determining means 55, motor rotation amount command means 56, A set rotation amount command means 57 is provided.

As the object to be dried is hung on the movable drying bar 6 at the collection position and the object to be dried is also hung on the stationary drying bar 7, and the drying operation for the dried object is started by the remote control device 20, the lowest position in the drying operation state Then, the movable drying bar 6 is stopped for a set time (for example, 10 seconds), the warm air is sent to the object to be dried, and the operation of the weight change width deriving means 52 for the drying bar is started.
When the set time elapses, the set rotation amount command means 57 outputs a drive output to the clothes raising / lowering electric motor 11, stops the dryer 4, drives the movable drying bar 6 and raises the set amount, and then stops. After stopping, the dryer 4 is driven to send warm air to the object to be dried.

This operation will be described with reference to the graph showing the time-dependent change in the measured weight in FIG. 11 and the overall schematic side view of the drying operation state in FIG.
First, at the lowest position P1 in the drying operation state, for example, the movable clothes drying bar 6 is stopped for 10 seconds, and warm air is sent to the object to be dried. The weight change width deriving means 52 for the clothes-drying bar plots the weight measured by the weight measuring means 23 every 0.5 seconds, for example, finds an average value for 10 seconds, and multiplies it by the object to be dried. It is derived as the range of change in weight from when it is not.
By driving the electric motor 11 for raising and lowering the clothesline, the fixed position of the movable clothes bar 6 is changed by the set height, and the above operation is repeated at each position to change the weight change width at each of P2, P3, P4, P5 and P6. It comes to derive.

  When the number of stops reaches a set number of times such as six, that is, when the movable drying bar 6 moves to the uppermost position P6 in the drying operation state, the fourth comparison means 53 causes the weight change width deriving means 52 for the drying bar. Is compared with the largest weight stored so far together with the position information in the large weight change width storage means 54, and the larger weight is stored in the large weight change width storage means 54 together with the position information. It comes to memorize. At the first fixed position, the previous weight becomes zero (or the weight when the object to be dried is not hung), so the weight measured by the weight measuring means 23 at the first fixed position is the large weight change width. It is stored in the storage means 54 together with the position information.

  In the drying bar optimum drying position determining means 55, the movable weight drying bar 6 is moved to the uppermost position P6 in the drying operation state, and the weight change width extracted and compared by the fourth comparison means 53 is larger. The position information, that is, the position where the weight change width is maximized is obtained, and the fixed position of the movable clothes bar 6 at that time is determined as the optimum drying position.

  The motor rotation amount command means 56 calculates the rotation amount of the electric motor 11 for lifting the clothesline corresponding to the optimum drying position determined by the drying position optimal determination means 55 for the drying bar, and for raising and lowering the clothesline so as to be the rotation amount. The electric motor 11 is driven and stopped, and the movable clothes bar 6 is stopped at the optimum drying position.

  After the set drying time (for example, 15 minutes) has elapsed after stopping at the optimal drying position and drying, the fixed rotation position of the movable clothes bar 6 is increased by the set rotation amount command means 57 so that the fixed position is raised. The raising / lowering electric motor 11 is driven and stopped by a set amount of rotation, and warm air is applied to the lower side of the object to be dried than at the optimum drying position. Further, this operation is repeated until the movable clothes bar 6 rises to the fixed position that is the uppermost position in the drying operation state.

Next, the drying control operation associated with the determination of the optimum drying position based on the above configuration will be described in order using the flowchart of FIG.
(1) Drying preparation process The drying preparation button is pushed by the remote control device 20. Thereby, the movable drying bar 6 and the screen 15 stored in the standby position are lowered to the collection position where the object to be dried is easily placed and stopped. Therefore, the object to be dried is hung on the movable drying bar 6 and the fixed drying bar 7. As an operation here, the object to be dried may be hung on the stationary drying bar 7 and then the drying preparation button may be pressed to move the movable drying bar 6 to the collection position, and the object to be dried may be hung there.

(2) Drying optimum position determination step After applying the object to be dried, the drying operation button is pushed. As the drying operation button is pushed, the clothes raising / lowering mechanism 17 is automatically driven to move the movable clothes drying bar 6 and the screen 15 to the lowest position P1 in the drying operation state and stop (N1).
Thereafter, the dryer 4 is operated (ON) for a set time (for example, 10 seconds) (N2), and a weight change width is derived based on the weight measured by the weight measuring means 23, and is calculated at the lowest position P1. The weight change width is stored in the large weight change width storage means 54 (N3).
Thereafter, the dryer 4 is stopped (OFF) for a set time (for example, 10 seconds) (N4), and the movable clothes-drying bar 6 and the screen 15 are moved to a position P2 where the set height is raised from the lowest position P1 in the drying operation state. It moves and stops (N5), and the dryer 4 is operated (ON) for a set time (for example, 10 seconds) (N6).

Meanwhile, the weight change width is derived based on the weight measured by the weight measuring means 23, and the large weight change width previously stored in the large weight change width storage means 54 (here, the weight change width at the lowest position P1). The larger weight change width is stored in the large weight change width storage means 54 together with the position information (N7).
Thereafter, the dryer 4 is stopped (OFF) for a set time (for example, 10 seconds) (N8), the movable clothes bar 6 and the screen 15 are moved to the position P3 where the set height is raised, and stopped, and the above-mentioned step N6 To N8 are repeated, and the same processing is performed for each of the positions P4, P5 and P6 (N9).
As a result of the above processing, the position having the maximum weight change width is determined as the optimum drying position (N10), and the movable clothes bar 6 and the screen 15 are moved to the optimum drying position and stopped (N11).

(3) Drying operation step Thereafter, the dryer 4 is operated (ON) (N12), and after confirming that a set time such as 15 minutes or 20 minutes has elapsed (N13), the electric motor for lifting and lowering the clothesline 11 is driven to raise the movable clothes bar 6 and the screen 15 to the set height (N14). The operations from Step N13 to Step N15 are repeated until the height of the movable clothes bar 6 and the screen 15 reaches the uppermost position P6 in the drying operation state.
Finally, the height of the movable clothes bar 6 and the screen 15 is set to the uppermost position P6 in the drying operation state, and the drying operation is performed until the drying operation is completed, for example, the dehydration rate reaches the set dewatering rate.

  In the second embodiment, the movable clothes-drying bar 6 is stopped at the optimum drying position without repeating the operation of raising the set height, and drying is performed. After the set drying time has elapsed, the electric motor for raising and lowering the clothes drying is performed only once. 11 may be configured to be driven and stopped by a set amount of rotation, and the movable drying bar 6 to be raised to a set height so that warm air is applied to the lower side of the object to be dried than at the optimum drying position.

  According to the above configuration, when the hot air from the dryer 4 is applied to the object to be dried, the position where the weight change width is the largest, that is, the position where the hot air effectively hits the object to be dried is the optimum position. And the drying operation for the object to be dried can be efficiently performed in a short time.

Although the structure which dries a to-be-dried object in the bathroom 1 was shown in the said Example, as a bathroom drying system of this invention, you may comprise so that a to-be-dried object may be dried in a dressing room.
Moreover, in the said Example, although the thing of the ceiling installation type was shown as the dryer 4, a wall hanging type may be sufficient.

  In the above embodiment, the movable clothes-drying bar 6 and the fixed clothes-drying bar 7 are provided as the clothes-drying bar. However, as the present invention, the fixed-drying bar 7 may not be provided.
