Fig. 2 is a schematic block diagram showing the internal structure of the dehumidifier of the first embodiment. Fig. 3 is a schematic perspective view of a variable wind direction means. Fig. 4 is a control block diagram of the dehumidifier of the first embodiment. Fig. 5 is a flow chart showing the operation of the dehumidifier in the clothes drying operation of the first embodiment.

Referring to Fig. 1, the outer casing of the dehumidifier J is constituted by a dehumidifier casing 100 (hereinafter referred to as a casing 100) which is constructed to be self-standing.

An exhaust port 101 for taking in the indoor air A into the interior and an exhaust port 103 for discharging the dry air B from which the moisture has been removed from the casing 100 are opened on the casing 100. Further, inside the casing 100, a water storage tank 102 is provided which stores moisture removed from the air taken in from the suction port 101.

The suction port 101 is opened on the back surface of the casing 100, and a screen for preventing dust from intruding into the inside of the casing 100 is provided in the opening.

A wind direction variable means 1 for changing the wind direction of the dry air B is provided in the exhaust port 103. The wind direction variable means 1 is composed of a longitudinal direction louver 1a in which the wind direction in the vertical direction is changed, and a horizontal direction louver 1b which can change the horizontal direction.

The water storage tank 102 is installed to be detachable from the inside of the casing 100.

Furthermore, see Figure 2, inside the dehumidifier J: for production A blower fan 2 that sucks in the indoor air A from the suction port 101 and discharges the airflow of the dry air B from the exhaust port 103; a fan motor 2a that rotates the blower fan 2; and detects the indoor air A sucked from the suction port 101 Temperature temperature sensor 3 (temperature detecting means); humidity sensor 4 for detecting the humidity of indoor air A (humidity detecting means); removing moisture contained in indoor air A to generate dehumidification of dry air B Means 5; a longitudinal variable motor 1c in which the longitudinal louver 1a is variable in the vertical direction; a lateral variable motor 1d in which the horizontal louver 1b is horizontally variable; and an infrared sensation as a surface temperature detecting means The detector 6 is a control circuit 7 as a control means for controlling each element.

Dehumidification means 5, located at the air path from the suction port 101 to the exhaust port 103 Medium is a device that removes moisture from the air and condenses it. The means used in the dehumidification means 5 is, for example, a method of constituting a heat pump circuit and condensing moisture in the air in the evaporator, or a desiccant for condensing moisture in the air removed by the adsorbent by a heat exchanger (Desiccant) ) Ways, etc.

The moisture removed from the indoor air A by the dehumidifying means 5 is condensed water C and accumulated in the water storage tank 102, and the air after removing the moisture becomes the dry air B.

Then, referring to Fig. 3, the longitudinal louver 1a constituting the wind direction variable means 1 has a rectangular opening extending in the width direction of the casing 100, and is configured to be capable of the above-described longitudinal variable motor 1c. The rotary axis changes the axis in the vertical direction.

Thereby, the wind direction can be changed in the longitudinal direction (up and down direction).

Further, the horizontal louver 1b is configured to be disposed at equal intervals in the longitudinal louver 1a, and is axially supported on the inner side opposite to the opening of the longitudinal louver 1a so as to be horizontally changeable, and the lateral direction Variable motor 1d Drive linkage.

Thereby, the wind direction can be changed in the horizontal direction (left-right direction).

The infrared sensor 6 is attached to one surface of the lateral louver 1b disposed in the center of the longitudinal louver 1a.

Thereby, the detection range of the surface temperature of the infrared ray sensor 6 is almost the same as the direction of the dry air B which is changed by the wind direction variable means 1. In other words, the infrared sensor 6 can detect the surface temperature of the entire region within the range in which the wind direction variable means 1 can supply air.

This infrared sensor 6 employs, for example, a device that utilizes a thermal power effect, an infrared ray absorbing film 6a that receives heat radiation (infrared rays) emitted from a surface of a predetermined region, and a thermal resistor that detects the temperature of the infrared absorbing film 6a. 6b (see Figure 3).

In the infrared sensor 6, the temperature (warm junction) of the heat sensitive portion of the infrared absorbing film 6a that absorbs heat and absorbs heat, and the temperature (cold junction) of the infrared absorbing film 6a detected by the thermistor 6b The difference is converted into an electric signal such as a voltage, and is input to the control circuit 7 to be described later. The surface temperature of a predetermined area can be judged by the magnitude of the electric signal.

When the control circuit 7 detects that the dehumidification mode is selected by the switching operation of the operation unit (not shown), the wind direction variable means 1 is driven to blow air from the exhaust port 103, and the fan motor 2a is driven to rotate the blower fan 2, and The dehumidification means 5 is driven to make the humidity in the room the optimum humidity.

Moreover, the control circuit 7 drives the longitudinal direction variable motor 1c and the lateral direction variable motor 1d of the wind direction variable means 1 to blow air in the direction of the desired area of the room.

Thereby, the indoor air A is sucked into the dehumidifier casing 100 from the suction port 101, and the temperature and humidity of the room are detected by the temperature sensor 3 and the humidity sensor 4, respectively, and then dehumidified by the dehumidifying means 5 to be dried. The air B is blown out from the exhaust port 103 to the inside of the room.

Next, referring to FIG. 4, the control circuit 7 and the control power are explained. Various sensors and electronic components connected to the road.

The control circuit 7 controls the overall operation of the dehumidifier J based on input from various sensors or various switches and a predetermined algorithm, and includes an input circuit 7a, an output circuit 7b, a CPU 7c, a memory unit 7d, and a measurement operation. The timer unit 7e of the operation time measuring means of the start time of the start of the calculation.

Furthermore, the memory unit 7d stores upper parts for controlling the dehumidifiers J. Descriptive algorithm. The algorithm includes: an operation control program for determining an operation control based on inputs of various sensors or switches, or an output signal based on the temperature sensor 9 and the humidity sensor 10 and an output of the timing unit to determine The running time of the running time determines the program.

The control circuit 7 thus constructed is connected through the input circuit 7a. The operation switch 8 for opening/closing the operation of the dehumidifier J, the temperature sensor 9, the humidity sensor 10, the infrared sensor 6, and the evaluation input means for evaluating the dryness of the user's input of the cleaning product Various sensors such as the switch 11 and various switches are evaluated.

Further, the dryness evaluation switch 11 may be replaced by the operation switch 8, as will be described later (after step S11). For example, the evaluation of the dryness can be estimated from the time when the user operates the switch 8.

Furthermore, the control circuit 7 is connected to the dehumidifier through the output circuit 7b. Electrical components such as the display unit 12, the dehumidifying device 5, the fan motor 2a, the longitudinal variable motor 1c, and the lateral variable motor 1d.

Next, referring to Fig. 5, the operation of each part of the dehumidifier J as described above in the drying operation of the clothes will be described.

In the following description, the time measurement, the humidity measurement, and the temperature measurement are performed by the timer unit 7e, the humidity sensor 10, and the temperature sensor 9, respectively, and the control circuit 7 performs various arithmetic processing based on the measured values.

In the control circuit 7 of the dehumidifier, when it is detected that the drying operation of the clothes is started, each element necessary for the dehumidification operation such as the dehumidification device 5 or the fan motor 2a is started to be driven, and the process proceeds to step S2. Next, in step S2, the measurement of the operation time t is started, and the process proceeds 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 proceeds to step S4. Furthermore, in the present embodiment, the core time is set to 70 minutes. Here, the so-called core time is used to dry the clothes to some extent before reaching the next step.

In step S4, after the core time has elapsed, the relative humidity detected by the humidity sensor 10 is judged every predetermined time (in the present embodiment, set to 10 minutes), and the humidity detection is continued until the pre-detection is detected. The relative humidity (in this example, 50% or less) is set (step S5). Then, when the preset relative humidity is reached, the process proceeds to step S6.

In step S6, the detection time t1 when the ambient relative humidity (humidity of the indoor air) exceeds 50% from the start of the operation, and the detection of the ambient temperature (the temperature of the indoor air) detected by the temperature sensor 9 are obtained. Temperature T, and move to step Step S7. Next, in step S7, the product of the detected temperature T and the operation time t1 is calculated, and the process proceeds to step S8.

Next, in step S8, the coefficient D is calculated and the process proceeds to step S9. This coefficient D is one of the variables for changing the drying operation time of the drying operation of the clothes, and is calculated based on the sub-form obtained by the experiment.

『D=a×(T×t1)^b』(“^” means power.)

Here, referring to Fig. 6, the coefficient a and the coefficient b are coefficients which are respectively set for each applicable level Dx.

The application level Dx is set in accordance with the dryness setting D1 to D5 of the target in advance, and each of the corresponding coefficient a and the coefficient b is obtained and applied in the previous operation by the processing after the step S11 described later. It.

Further, in the present embodiment, the application level Dx is set to five stages. However, if it is necessary to change the operation time of the clothes drying operation more finely, it is also possible to set it to five or more stages, and if not, It is necessary to change the running time in detail, or it can be set to less than 5 segments.

Furthermore, in the state of the first operation, the initial value D3 is set. In addition, the target dryness, the higher the value, the higher the degree of drying. That is, in this example, D5 is the level with the longest running time, and D1 is the level with the shortest running time.

Further, the coefficient a and the coefficient b of each level of the application level Dx are stored in the storage unit 7d of the control circuit 7, and when the level is increased or decreased depending on the evaluation information of the user, which will be described later, the coefficient in the applicable level is used. a and the coefficient b are read in and used for calculation.

Then, in step S9, the remaining dehumidification is calculated based on the coefficient "Y=t1×(D-T/100)" obtained from the experiment using the coefficient D obtained in step S8. The turning time Y determines the remaining dehumidifying operation time Y, and moves to step S10.

After that, if the user does not stop running, the clothes are dried. The operation is continued until the remaining dehumidification operation time Y has elapsed, but it is determined in step S10 whether or not the operation time has reached Z. The operation time Z is the time during which the drying of the washing material is carried out to some extent, which is set by the experiment. After the operation time Z, the user's evaluation of the dryness of the clothes is effective. (Evaluation of the dryness of clothing from the user's use form.)

When the operation time reaches Z in step S10, the process proceeds to step S11.

Here, the process after step S11 is effective on the condition that the predetermined operation time Z has elapsed. This is to stop the operation due to the erroneous operation of the operation switch 8 or the like during the drying operation of the clothes, and is excluded for use in step S11. In addition, in the present embodiment, the change of the applicable level Dx is evaluated as Y>Z.

For example, in the case of the operation of the step S10, when the operation is stopped due to an erroneous operation shortly after the start of the drying operation of the clothes, the evaluation of the degree of dryness in the state in which the clothes are almost completely dry can be eliminated, and the misjudgment can be prevented. Improve the accuracy of judgment.

Next, after step S11, the flow of the evaluation of the dryness of the clothes is provided for the user.

Further, in the present embodiment, the user's evaluation of the degree of drying of the clothes is estimated by the time point 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 user has stopped the operation before the dehumidification operation time Y has elapsed by operating the operation switch.

Originally, in step S12, it is determined whether or not the remaining dehumidification operation time Y calculated in step S9 has been reached, and then the clothes drying operation is ended in step S13.

However, the user confirms the degree of drying of the laundry before the dehumidification operation time Y, and determines that the subsequent drying operation is unnecessary. If the operation is stopped before the process proceeds to step S12, the process proceeds to step S21.

Here, a judgment count is provided in the memory unit 7d, which is based on the above. The presumed user evaluates the increase in the degree of dryness of the clothes. In addition, the initial value of the judgment count is 0.

In step S21, the calculation for judging the count down 1 is performed, and the result of the calculation is stored in the storage unit 7d, and the flow proceeds to step S22.

In step S22, it is determined whether the cumulative count of the judgment count is The predetermined value ("-2" in the present embodiment) is equal to or less.

In the present embodiment, it is determined whether or not the user has stopped the operation twice before the remaining dehumidification time Y has elapsed during the current and past clothes drying operation. In other words, whether the user indicates that it is not necessary to operate to the dehumidification time Y, and it is possible to prevent erroneous determination such as erroneous input or mischief other than the user.

Then, the process proceeds to step S23, and the aforementioned applicable level Dx, etc. The level is lowered by one level to determine the level to apply at the next run. In addition, the judgment count is reset at the same time.

As described above, the user stops the operation before the dehumidification operation time Y passes, whereby the dehumidification operation time Y is corrected in the direction of shortening in the subsequent operation.

Further, in the present embodiment, in step S22, it is determined that the cumulative count of the count is "-2", but if it is set to easily change the coefficient D level, The cumulative count may be "-1", and if it is set to be difficult to change the coefficient D level, the cumulative count may be a value lower than "-2".

In addition, when the remaining dehumidification operation time Y is stopped, the determination count is reduced by one point. However, the size of the subtraction point may be converted according to the time point of the stop time. For example, in the case of early stop, the number of points to be reduced can be increased, and the closer to the dehumidification time Y, the smaller the number of points to be subtracted.

Then, in step S11, if the user does not stop the operation before the remaining dehumidification time Y has elapsed, 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 satisfied (the time Y has elapsed), the process proceeds to step S13 to temporarily end the clothes drying operation. Thereafter, in step S14, the internal transition to the standby state. In addition, the so-called standby state is a state in which dehumidification and air supply are stopped.

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

The limit time is set in the above standby state, 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 proceeds to step S17, and the operation is ended. In the present embodiment, the time limit is 5 hours.

Here, when the dehumidifier is in the standby state, it is determined in step S15 whether the user presses the operation switch 8 again to start the clothes drying operation. When it is estimated that the user has confirmed the degree of dryness of the laundry, it is determined that the drying operation must be performed again. If the operation is restarted before the process proceeds to step S17, the process proceeds to step S31.

In step S31, the calculation of the judgment count accumulation 1 is performed, and the process proceeds to step S32. And the result is stored in the memory unit 7d.

Then, in step S32, it is determined whether or not the cumulative count of the determination count is equal to or greater than a predetermined value ("+2" in the present embodiment).

That is, in the present embodiment, it is determined whether or not the user has restarted the operation twice after the remaining dehumidification time Y has elapsed twice during the drying operation of the clothes in the past and the past. That is, whether the user indicates that the clothes have to be dried again after the operation to the dehumidification time Y is performed, and erroneous determination such as mis-inputation or mischief other than the user can be prevented.

Then, the process proceeds to step S33, and the level of the aforementioned applicable level Dx is increased by one step, and the level applicable at the next operation is determined. In addition, the judgment count is reset at the same time, and the process proceeds to step S34, and the additional clothes drying operation is executed.

As described above, since the user resumes the operation in the standby state, the operation time is corrected in the extended direction.

The above control process is organized as follows.

(1) The case where the user stops the operation before the remaining dehumidification operation time Y has elapsed.

It is presumed that the user has judged that dehumidification is sufficient at a stage earlier than the remaining dehumidification operation time Y that has been set. After the next operation, the remaining dehumidification operation time Y is shortened to be shorter than this time (change the applicable level Dx to decrease).

(2) The dehumidification is performed until the remaining dehumidification operation time Y (when the additional operation is not performed).

It is presumed that the user judges that dehumidification according to the remaining dehumidification operation time Y that has been set is sufficient. That is, it is determined that there is no remaining dehumidification time according to the setting. questionable. In the next and subsequent operations, the dehumidification operation time Y (the application level Dx is not changed) is obtained by using the coefficient of the dehumidification operation time Y set this time.

(3) When the dehumidification is performed until the remaining dehumidification operation time Y, the user additionally performs the operation.

It is speculated that the user judges that dehumidification is not enough. In the next operation, the remaining dehumidification operation time Y is extended to be longer than this time (change the applicable level Dx to increase).

Here, in the present embodiment, an example of the description is made by using When the user stops the operation (that is, the time when the user operates the operation switch 8), the user is estimated to evaluate the degree of dryness of the clothes, and is regarded as an input of the evaluation information, and the operation time is corrected when the general operation is performed. However, the present invention is not limited thereto, and the dryness evaluation switch 11 as shown in Fig. 4 may be provided, and the evaluation information may be actively input by the user.

In the case where the user inputs the evaluation of the dryness by the dryness evaluation switch 11, the above-mentioned (1) to (3) are respectively equivalent to the evaluation "excessive drying" and (2) the evaluation evaluation. It is just right, and (3) is equivalent to the evaluation of "under-drying".

According to the present embodiment, as described above, the cleaning as the object to be dried The degree of dryness of the laundry is corrected by the user's evaluation of the degree of drying of the clothes, and the operation time determined by the control circuit 7 is corrected, and the operation is controlled by the corrected operation time.

Further, the evaluation information of the user input by the evaluation information input means can be stored in the storage unit 7d, and the correction amount of the operation time can be changed by the repeated evaluation by the user. In this way, the user's satisfaction with the drying is used as the evaluation information and reflected in the running time of the drying operation of the clothes, and the personal preference can be performed. The dry operation of the cleaning products.
