Fig. 3 shows a schematic perspective view of the wind direction variable device. FIG. 4 shows a control block diagram of the dehumidifier of this embodiment. FIG. 5 is a flowchart showing the operation of the dehumidifier according to the present embodiment during the clothes drying operation.

Referring to FIG. 1 , the housing of the dehumidifier J is constituted by a dehumidifier housing 100 (hereinafter referred to as the housing 100 ) configured to be self-supporting.

The housing 100 is provided with a suction port 101 for taking in indoor air A and an exhaust port 103 for discharging dry air B from which moisture has been removed from the housing 100 into the room. In addition, a water storage tank 102 is provided inside the housing 100 to store moisture removed from the air taken in through the suction port 101 .

The suction port 101 is opened on the back surface of the housing 100 , and a filter for preventing dust from entering the housing 100 is provided on the opening.

The wind direction variable device 1 capable of changing the wind direction of the dry air B is provided on the exhaust port 103 . The wind direction variable device 1 is composed of a vertical louver 1a capable of changing the wind direction in the vertical direction and a horizontal louver 1b capable of changing the wind direction in the horizontal direction.

The water storage tank 102 is mounted detachably from the inside of the housing 100 .

In addition, with reference to Fig. 2, be provided with in the inside of dehumidifier J: blower fan 2, produce the airflow that sucks room air A from suction port 101, discharges dry air B from exhaust port 103; Fan motor 2a, makes this blower fan 2 rotations; temperature sensor 3 (temperature detection device), detects the temperature of the indoor air A sucked from the suction port 101; humidity sensor 4 (humidity detection device), detects the humidity of indoor air A; dehumidification device 5, removes the humidity contained in the indoor Moisture in the air A and generate dry air B; the vertical variable motor 1c makes the vertical shutter 1a variable in the vertical direction; the horizontal variable motor 1d makes the horizontal shutter 1b change in the horizontal direction; the infrared sensor 6 is used as a surface temperature detection device; and a control loop 7 as a control device for controlling each part.

The dehumidifier 5 is located in the air path from the suction port 101 to the exhaust port 103, and removes moisture in the air and condenses it. As examples of the system used in this dehumidifier 5, a system in which a heat pump circuit is formed to condense moisture in the air in an evaporator, and a desiccant system in which moisture removed from the air by an adsorbent is condensed by a heat exchanger are used. Wait.

The moisture removed from the indoor air A by the dehumidifier 5 is stored as condensed water C in the water storage tank 102 . The air from which moisture has been removed becomes dry air B.

Next, referring to FIG. 3, it can be seen that the vertical louver 1a constituting the wind direction variable device 1 has a rectangular opening extending in the width direction of the frame body 100, and is configured so that it can basically take the rotation axis of the aforementioned vertical variable motor 1c as an axis. And variable along the vertical direction.

Thus, the wind direction can be changed in the vertical direction (vertical direction).

In addition, the horizontal louvers 1b are arranged at equal intervals in the vertical louver 1a, and can be variably supported in the horizontal direction on the inner side on the opposite side of the opening of the vertical louver 1a, and are driven by the aforementioned horizontal variable motor 1d. Gearing.

Thereby, it is comprised so that the wind direction can be changed laterally (left-right direction).

The infrared sensor 6 is attached to one surface of the horizontal louver 1b arranged substantially in the center of the vertical louver 1a.

Thus, the detection range of the surface temperature by the infrared sensor 6 is substantially the same as the direction of the dry air B that can be changed by the wind direction variable device 1 . That is, the infrared sensor 6 can detect the surface temperature of the entire area within the range in which the wind direction variable device 1 can blow air.

The infrared sensor 6 is, for example, a device that utilizes the thermoelectromotive force effect, and is composed of an infrared absorbing film 6a that receives heat radiation (infrared rays) emitted from the surface of a predetermined area, and a thermistor 6b that detects the temperature of the infrared absorbing film 6a (refer to image 3).

The infrared sensor 6 converts the difference between the temperature (hot junction) of the heat-sensitive part of the infrared absorption film 6a heated up by absorbing thermal radiation and the temperature (cold junction) of the infrared absorption film 6a detected by the thermistor 6b. It is an electrical signal such as a voltage, and is input to a control circuit 7 described later. The surface temperature of a predetermined area can be determined from the magnitude of the electric signal.

When the control circuit 7 detects that the dehumidification mode is selected through the switch operation of the operation part (not shown), it can drive the wind direction variable device 1 to blow air from the exhaust port 103, and drive the fan motor 2a to make the blower fan 2 rotates to drive the dehumidifier 5 so that the humidity in the room becomes the optimal humidity.

In addition, the control circuit 7 drives the vertical variable motor 1c and the horizontal variable motor 1d of the wind direction variable device 1 to blow air in the direction of a desired area in the room.

Thus, indoor air A is taken into the dehumidifier frame 100 from the suction port 101, and the temperature and humidity in the room are detected by the temperature sensor 3 and the humidity sensor 4, respectively, and then dehumidified by the dehumidifier 5 to form dry air. B, blowing out from the exhaust port 103 into the room.

Next, the control circuit 7 and various sensors and electronic components connected to the control circuit will be described with reference to FIG. 4 .

The control circuit 7 controls the overall operation of the dehumidifier J according to various sensors or various switch inputs and prescribed algorithms. The timing part 7e of the running time measuring device of the running time.

Moreover, the said algorithm for controlling each part of the dehumidifier J is memorize|stored in the memory|storage part 7d. This algorithm includes: an operation control program for determining operation control based on input from various sensors or switches; and a program for determining the subsequent operation time based on the detection signals of the temperature sensor 9 and the humidity sensor 10 and the output of the timer. Operation time determination procedure.

In the control circuit 7 constituted in this way, the operation switch 8 for switching on and off the operation of the dehumidifier J, the temperature sensor 9, the humidity sensor 10, the infrared sensor 6, and a device for inputting laundry by the user are connected via the input circuit 7a. Various sensors such as dryness evaluation switch 11 and various switches of evaluation input device for dryness evaluation.

In addition, the dryness evaluation switch 11 may be replaced by the operation switch 8 as shown in the description of the operation described later (step S11 and later). For example, the evaluation of the dryness may be estimated from the time when the user operates the operation switch 8 .

In addition, electrical components such as a display unit 12 for reporting the state of the dehumidifier, a dehumidifier 5, a fan motor 2a, a vertically variable motor 1c, and a horizontally variable motor 1d are connected to the control circuit 7 via an output circuit 7b. .

Next, with reference to FIG. 5 , the operation of the dehumidifier J configured with each part as described above during the clothes drying operation will be described.

In addition, in the following description, time measurement, humidity measurement, and temperature measurement are performed by the above-mentioned timer unit 7 e , humidity sensor 10 , and temperature sensor 9 , respectively, and various calculation processes are executed by the control circuit 7 .

In step S1, when the control circuit 7 of the dehumidifier detects that the laundry drying operation has started, it starts to drive each part necessary for the dehumidification operation, such as the dehumidifier 5 and the fan motor 2a, and proceeds to step S2. Then, in step S2, the measurement of the operating time t is started, and the process goes to step S3.

In step S3, the dehumidification operation is continued for a predetermined set time (core time), and when the core time is reached, the process goes to step S4. In addition, in this embodiment, the core time is set to 70 minutes. Here, the core time refers to the time for drying the laundry to some extent before reaching the next step.

In step S4, after the core time has elapsed, the relative humidity of the air detected by the humidity sensor 10 is determined at regular intervals (set to 10 minutes in this embodiment), and the humidity detection is continued until the preset humidity is detected. Set relative humidity (below 50% in this example) until (step S5). And when reaching the preset relative humidity, it transfers to step S6.

In step S6, the operation time t1 from the start of the operation when the relative air humidity (the humidity of the room air) is lower than 50%, and the detected temperature T as the air temperature (the temperature of the room air) detected by the temperature sensor 9 are obtained. , turn to step S7. Then, in step S7, the product of the detected temperature T and the operating time t1 is calculated, and the process proceeds to step S8.

Next, the coefficient D is calculated in step S8 and the process goes to step S9.

The coefficient D is a variable for changing the drying operation time of the laundry drying operation, and is calculated by the following equation obtained experimentally.

D=a×(T×t1)＾b (“＾” means power.)

Here, referring to FIG. 6 , it can be seen that the coefficient a and the coefficient b are respectively set for the application rank (rank) Dx.

This application sequence Dx is set with D1 to D5 according to the target dryness, has coefficient a and coefficient b corresponding to each, and is obtained and applied by the processing after step S11 described later in the previous operation.

In addition, in this embodiment, the application sequence Dx is set to 5 levels, if it is necessary to change the running time of the clothes drying operation more accurately, it can also be set to more than 5 levels, and if it is not necessary to change the The running time can also be set to less than 5 levels.

In addition, in the state of initial operation, an initial value D3 is set. In addition, with regard to the target dryness, the higher the numerical value, the higher the degree of dryness. That is, in this example, D5 is the order with the longest operation time, and D1 is the order with the shortest operation time.

In addition, the coefficients a and b of the order for each application order Dx are stored in the storage unit 7d in the control circuit 7, and the coefficient a of the applied order is read when the order rises and falls according to user evaluation information described later. and b for calculation.

Next, in step S9, using the coefficient D obtained in step S8, the formula obtained by experiment

Y=t1×(D-T/100)

Calculate the remaining dehumidification operation time Y, determine the remaining dehumidification operation time Y, and turn to step S10.

Subsequently, if the user does not stop the operation, the laundry drying operation is performed until the remaining dehumidification operation time Y elapses, but whether the operation time has reached Z is determined in step S10. The operating time Z is the time for the laundry to dry to a certain extent, which is set based on experimental values. After the operating time Z, the user's evaluation of the dryness of the laundry is effective. (The evaluation of the dryness of the clothes is obtained according to the user's usage pattern.)

When the operating time reaches Z in step S10, the process goes to step S11.

Here, the processing after step S11 is enabled on the condition that the predetermined operation time Z has elapsed. In the present embodiment, Y>Z is set to stop operation due to misoperation of the operation switch 8 or the like during the clothes drying operation.

For example, step S10 can exclude the evaluation of the degree of dryness when the clothes are not dry when the operation is stopped due to misoperation shortly after the start of the clothes drying operation, thereby preventing misjudgment and improving the accuracy of judgment.

Next, after step S11 is the flow of the user's evaluation of the dryness of the laundry.

In addition, in the present embodiment, the user's evaluation of the degree of dryness of the clothes is estimated from the time when the user stops the operation, that is, the time when the user operates the operation switch 8 .

In step S11, it is determined whether or not the operation is stopped before the dehumidification operation time Y elapses by the user operating the operation switch.

Originally, after step S12 of judging whether or not the remaining dehumidification operation time Y calculated in step S9 has been reached, the clothes drying operation is ended in step S13.

However, if the user checks the dryness of the laundry before the dehumidification operation time Y elapses, and judges that the subsequent drying operation is unnecessary, and stops the operation before turning to step S12, then turn to step S21 in this case.

Here, a determination count is provided in the storage unit 7d, and the count is increased or decreased based on the user's evaluation of the degree of dryness of the laundry estimated as described above. However, the initial value of the judgment count is set to 0.

In step S21, the judgment count is decremented by 1, and the result is stored in the storage unit 7d, and the process proceeds to step S22.

In step S22, it is determined whether or not the accumulated count of the determination count is equal to or less than a predetermined value ("-2" in this embodiment).

In the present embodiment, it is determined whether or not the user stopped the operation twice before the remaining dehumidification time Y elapsed during the current and past laundry drying operations. That is, in addition to judging whether or not the user does not need to operate until the dehumidification time Y, misjudgment due to erroneous input or mischief by someone other than the user is prevented.

Thereafter, the process goes to step S23, and the order of the aforementioned application order Dx is lowered by one, and the order of application at the next operation is determined. In addition, the judgment count is reset at the same time.

As described above, the user stops the operation before the remaining dehumidification operation time Y elapses, thereby making corrections during the subsequent operation to shorten the dehumidification operation time Y.

In addition, in this embodiment, in step S22, the cumulative count of the determination count is set to "-2", and if the order of the coefficient D is easily changed, the cumulative count may be set to "-1". , if it is set so that the D order is difficult to change, the cumulative count can be set to a value smaller than "-2".

In addition, when the stop is before the remaining dehumidification time Y, the determination count is decremented by 1, and the magnitude of the number of points subtracted from the stopped time may be changed. For example, the earlier the stop, the greater the number of subtracted points can be, and the closer to the dehumidification time Y, the smaller the number of subtracted points can be.

Next, in step S11, when the user does not stop the operation until the remaining dehumidification time Y elapses, it is determined in step S12 whether or not the time Y calculated in step S9 has been reached.

In step S12, when the operation end condition is met (when time Y has elapsed), the process goes to step S13 and the clothes drying operation is temporarily terminated. Thereafter, in step S14, it internally shifts to the standby state. Here, the standby state refers to a state in which dehumidification and air blowing are stopped.

In step S12, when the operation end condition is not satisfied (when the time Y has not passed), the process goes to step S11.

In this standby state, a time limit is set, and it is determined in step S16 whether or not a predetermined time has elapsed. When the predetermined time has elapsed in the standby state, the process goes to step S17 to end the operation. This limited time is set to 5 hours in this embodiment.

Here, when the dehumidifier is in the standby state, it is determined in step S15 whether or not the user has pressed the operation switch 8 again to start the clothes drying operation. The start of re-run means that the user confirms the dryness of the laundry and presumably judges that the re-drying operation is necessary. If the re-run has started before going to step S17, the process goes to step S31.

In step S31, the judgment count is incremented by 1, and the process goes to step S32. In addition, the result is stored in the storage unit 7d.

Then, in step S32, it is determined whether or not the accumulated count of the determination count has reached a predetermined value ("+2" in this embodiment) or more.

That is, in the present embodiment, it is determined whether the user has restarted the operation twice after the remaining dehumidification time Y has elapsed in the current and past clothes drying operations, that is, in addition to whether the user has operated In addition to judging that there is still a desire to dry the clothes again by the dehumidification time Y, misjudgment due to erroneous input or mischief by someone other than the user is also prevented.

Thereafter, the process turns to S33, and the above-mentioned application order Dx is increased by one, and the order of application in the next operation is determined. At the same time, the determination count is reset, and the process goes to step S34 to perform an additional laundry drying operation.

As described above, the user makes corrections by restarting the operation in the standby state, thereby prolonging the operation time.

The above control flow is summarized as follows.

(1) When the user turns off the operation before the remaining dehumidification operation time Y elapses.

It is presumed that the user has judged that dehumidification is sufficient before the set remaining dehumidification operation time Y. After the next operation, the remaining dehumidification operation time Y is shortened compared with this time (the application order Dx is decreased).

(2) When dehumidification is performed until the remaining dehumidification operation time Y (case where no additional operation is performed).

It is presumed that the user has judged that dehumidification is sufficient within the set remaining dehumidification operation time Y. That is, it is determined that there is no problem within the set remaining dehumidification time. After the next operation, the dehumidification operation time Y is obtained by the coefficient of the dehumidification operation time Y set this time (the application order Dx does not change).

(3) After performing dehumidification until the remaining dehumidification operation time Y, the user adds an operation.

It is presumed that the user judges that the dehumidification is insufficient. After the next operation, the remaining dehumidification operation time Y is extended (the application order Dx is changed upwards) compared with this time.

Here, in this embodiment, the user's evaluation of the degree of dryness of the clothes is estimated from the time when the user stops the operation, that is, the time when the user operates the operation switch 8, and this is regarded as an input of evaluation information, which is related to It is related to the correction of the running time during normal operation. Although this embodiment has been described as an example, it is not limited to this. A dryness evaluation switch 11 as shown in FIG. 4 may also be provided, and the user actively enter evaluation information.

In addition, when the user inputs the dryness evaluation through the dryness evaluation switch 11, the above-mentioned (1) to (3) respectively correspond to the evaluations, wherein the evaluation "too dry" corresponds to (1), and the evaluation "moderate" corresponds to the evaluation. " corresponds to (2), and the evaluation "insufficient drying" corresponds to (3).

According to the present embodiment as described above, regarding the degree of dryness of the laundry as the object to be dried, the operation time determined by the control circuit 7 is corrected according to the user's evaluation of the degree of dryness of the clothes, so that the corrected operation Time controls the operation.

In addition, the user's evaluation information input by the evaluation information input device may be stored in the storage unit 7d, and the correction amount of the operating time may be changed by the user's repeated evaluation. In this way, the user's satisfaction with drying is reflected in the operation time of the laundry drying operation as evaluation information, and the laundry drying operation suitable for personal preference can be performed.
