Embodiment 1

Fig. 1 is a perspective view showing the appearance of a dehumidifier of the first embodiment. 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.

The suction port 101 for taking in the indoor air P into the inside and the exhaust port 103 for discharging the dry air Q 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.

The exhaust port 103 is provided with a wind direction that allows the wind direction of the dry air Q to be changed. Change means 1. 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. Further, the infrared sensor 6 is provided in the wind direction variable means 1.

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

Further, referring to Fig. 2, inside the dehumidifier J, a blower fan 2 for generating an air flow for sucking the indoor air P from the suction port 101 and discharging the dry air Q from the exhaust port 103 is provided; and the blower fan 2 is provided The rotating fan motor 2a; the temperature sensor 3 (temperature detecting means) for detecting the temperature of the indoor air P sucked from the suction port 101; and the humidity sensor for detecting the humidity of the indoor air P sucked from the suction port 101 4 (humidity detecting means); a dehumidifying means 5 for removing moisture contained in the indoor air P to generate dry air Q; a longitudinal direction variable motor 1c for making the longitudinal louver 1a variable in the vertical direction; The plate 1b is a horizontal direction variable motor 1d which is variable in the horizontal direction, an infrared sensor 6 as a surface temperature detecting means, and a control circuit 7 as a control means for controlling each element.

The dehumidification means 5 is located in the air passage from the suction port 101 to the exhaust port 103, and is a means for removing moisture from the air and condensing 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 P 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 Q.

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 is the axis Change 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 The driving of the variable motor 1d is interlocked.

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 Q 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.

The infrared ray sensor 6 employs, for example, a device that utilizes a thermal power-up effect, an infrared ray absorbing film 6a that receives heat radiation (infrared ray Z) emitted from a surface of a predetermined region, and a temperature resistance 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.

In the present embodiment, the infrared sensor 6 is used to distinguish the object to be dried R such as a cleaning object from the difference in surface temperature of the detected object.

Referring to FIGS. 5 and 6, the control circuit 7 separates the detectable area A of the infrared sensor 6 into a square of a predetermined size, and judges the surface temperature of each of the cells, thereby judging the position of the object R to be dried or The degree of dryness.

For example, it is detected that the portion B covered by the shadow in the detectable area A is in a state in which the temperature is lower than the other portions. In addition, the lower the temperature of the shadow in the figure, the lower the temperature.

Further, the control circuit 7 determines that the portion having a low surface temperature has a cleaning object, and controls the direction of the wind direction changing means 1 or the operation of the fan motor during the dehumidifying operation so that the dehumidified air is efficiently blown to the position.

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.

Further, the control circuit 7 drives the vertical direction variable motor 1c and the lateral direction variable motor 1d so as to blow air in the direction of the desired area in the room.

Thereby, the indoor air P 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 Q is blown out from the exhaust port 103 to the inside of the room.

Next, referring to Fig. 4, the control circuit 7 and various sensors and electronic components connected to the control circuit will be described.

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. Starting from the beginning The timing unit 7e of the operation time measuring means of the operation time.

Furthermore, the memory unit 7d stores the above algorithm for controlling each part of the dehumidifier J. 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 configured is connected to the on/off operation switch 8 that performs the operation of the dehumidifier J, the temperature sensor 9, the humidity sensor 10, the infrared sensor 6, and the user input through the input circuit 7a. Evaluation of the evaluation of the dryness of the laundry The various sensors such as the switch 11 and various switches are evaluated for the dryness of the input means.

Further, the dryness evaluation switch 11 may be replaced by the operation switch 8, as will be described later (after step S17). For example, the evaluation of the dryness can be estimated from the time when the user operates the switch 8.

Further, the control circuit 7 is connected to an electric component 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 that notify the state of the dehumidifier through the input circuit 7a.

Next, referring to Fig. 7, the operation of each part of the dehumidifier J as described above in the drying operation of the clothes will be described.

Further, 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, the temperature sensor 9, and the infrared sensor 6, respectively, and the control circuit 7 determines these measurements. The values are processed in various ways.

In the control circuit 7 of the dehumidifier, in step S1, when it is detected that the drying operation of the clothes is started, the dehumidifying operation such as driving the dehumidifying device 5 or the fan motor 2a is started. The required components are moved to step S2.

Then, in steps S2 to S9, the amount of the object to be dried R and the degree of drying of the object to be dried R are detected, and the applicable level Dx of the clothes drying operation and the amount and the amount of the object to be dried R are determined. The update value of the judgment count table of the applicable grade Dx table to which the drying operation of the dry matter R is the same as the drying state of the clothes.

Here, referring to Fig. 8, the application level Dx is set in advance in accordance with the dryness setting of the target D1 to D5, and each has a corresponding coefficient a and coefficient b. In the previous operation, step S17 described later is used. The subsequent processing is determined and applied to conditions such as the amount of the object to be dried R and the ease of drying of the object R to be dried.

Further, the coefficient a and the coefficient b are coefficients set for each applicable level Dx, and the dehumidification time Y is calculated in steps S14 and S15 which will be described later.

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 may be set to five or more stages, and if it is not necessary, it will be operated. Time changes can be set to less than 5 segments.

Then, referring to Fig. 9(b), the applicable level Dx is the "large", "medium", and "small" of the area occupied by the object R to be dried by the infrared sensor 6. And the ease of drying of the dried object R is "normal" and "easy to dry", and is set to six object values.

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.

In addition, the coefficient a and the coefficient b of each level of the applicable level Dx are stored in the control. In the memory unit 7d of the system 7, when the level is lowered in accordance with the evaluation information of the user, which will be described later, the coefficient a and the coefficient b in the applicable level are read and used for calculation.

Further, referring to Fig. 9(a), the update value of the count table is judged to be "large", "medium", or "small" in the size of the area occupied by the object R to be dried by the infrared sensor 6. And the ease of drying of the dried material R is "normal" and "easy to dry". The situation of the six patterned dried objects R ("large area, normal", "large area, easy to dry", "area" Medium, normal, "area, easy to dry", "small area, normal", "small area, easy to dry") Set the count value.

Then, the count value is changed in steps S41 and S31 to be described later, and the amount of each object to be dried R and the object to be dried R are easily dried in steps S42 to S43 and steps S32 to S33 based on the count. The change of the applicable level Dx shown in Fig. 9(b) is judged by the condition of the degree or the like.

Returning to Fig. 7, first, in step S2, the infrared ray sensor 6 and the wind direction variable means 1 on which the infrared ray sensor 6 is mounted are driven to measure the surface temperature of each of the regions in which the dehumidified air can be blown. And it goes to step S3.

Furthermore, the initial operation of the infrared sensor 6 can be performed before or after the driving of the dehumidifying device 5 or the fan motor 2a.

In step S3, the square (region) of the position of the object R to be dried is estimated from the surface temperature of the respective parties measured in step S2, and the number m1 of the squares is counted (shown in Fig. 6). The number of squares of part B (the portion covered by the shadow) is transferred to step S4. The estimation criterion of the square where the object R to be dried may be the position where the temperature is lower than the surrounding square, or the temperature Squares below the established temperature are the object.

Further, the square at the position where the object to be dried R is located is a special blowing region for actively blowing the dehumidified air by the wind direction variable means 1 during the dehumidifying operation.

Next, in step S4, based on the number m1 of the squares counted in step S3, the applicable area of the adaptation level Dx is determined, and the process proceeds to step S5. That is, in this step, the amount of the object R to be dried is observed. The larger the number m1 of squares, the larger the area of the square occupied by the laundry, so that it can be determined that the number of objects R to be dried is larger.

In the present embodiment, the number of squares corresponding to the applicable area is divided into three segments: "large (b≦m1)", "medium (a≦m1<b)", and "small (m1<a)".

Next, in steps S5 and S6, the dehumidification operation is performed for a predetermined period of time.

In the present embodiment, the dehumidification operation is performed for 60 minutes (step S6), and the process proceeds to step S7. In addition, during the dehumidifying operation, the infrared sensor 6 is used to measure the degree of drying of the special blowing region of the square in which the object R is to be dried every 10 minutes, and the drying count is added to the square determined to be dry. 1 point (step S5).

The addition of the dry count of the square is used to determine the degree of drying of the dried object R, and the more the dry count is added, the more the dried object R located at the square position can be judged to be dry.

In step S7, the number m2 of squares whose dry count is added to a predetermined number of points or more is calculated, and the flow proceeds to step S8. In the present embodiment, the number of squares added to two or more points is calculated. That is, the portion having the portion to be dried is calculated by the portion of the portion B which is reduced in the process of Fig. 6(a) to Fig. 6(b) The grid is the object.

In the step S8, m2/m1 is calculated. If the value is equal to or greater than the predetermined value, the process proceeds to step S9, and the drying easiness of the object to be dried R of the application level Dx is switched to "easy drying", and the process proceeds to step S10.

When the value of m2/m1 is less than the predetermined value, the ease of drying of the object R to be dried at the application level Dx is "normal", and the process proceeds to step S10.

In the present embodiment, the determination reference value of m2/m1 is set to 0.8, so that it is determined to be "easy to dry" if it is dried by 80% or more.

That is, in the step S8, the step of determining the easiness of drying of the dried object R to be dried is determined. In other words, the more the number of m2 in which the dried material R has dried in a predetermined period of time, the more the dried object R which is easy to dry.

Then, in step S10, the relative humidity of the environment detected by the humidity sensor 10 is determined every predetermined time (in the present embodiment, 10 minutes), and the humidity detection is continued until the preset relative is detected. The humidity (in this example, 50% or less) (step S11).

Then, when the preset relative humidity is reached, the process proceeds to step S12.

In step S12, 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. The temperature T is shifted to step S13. Next, in step S13, the product of the detected temperature T and the operation time t1 is calculated, and the process proceeds to step S14.

Next, in step S14, the coefficient D is calculated and the process proceeds to step S15.

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 subroutine obtained by the experiment, and the process proceeds to step S15. 『D=a×(T×t1)^b』(“^” means power.)

Here, the coefficient a and the coefficient b are values corresponding to the applicable level Dx selected in S2 to S9 (Fig. 8).

Then, in step S15, the remaining dehumidification operation time is calculated based on the coefficient "Y=t1 × (D-T/100)" obtained from the experiment using the coefficient D obtained in step S14, and the process proceeds to step S16.

Thereafter, if the user does not stop the operation, the clothes drying operation is performed until the remaining dehumidification operation time elapses, but it is determined in step S16 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 S16, the process proceeds to step S17.

Here, the process after step S17 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 S17. 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 S16, 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 S17, the flow of evaluation of the clothes dryness by the user is performed.

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 S17, 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 S18, it is judged whether or not the remaining dehumidification operation time Y calculated in step S15 has been reached, and then the clothes drying operation is ended in step S19.

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 S18, the process proceeds to step S31.

Here, the memory unit 7d is provided with a judgment count based on the evaluation of the degree of drying of the clothes by the user estimated as described above, and the increase or decrease of the count is performed. In addition, the initial value of the judgment count is 0.

In step S31, the calculation of the judgment count subtraction 1 which is the object value of the updated setting count table selected in S2 to S9 is executed, and the result of the calculation is stored in the storage unit 7d, and the flow proceeds to step S32.

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

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 S33, and the applicable level Dx of the condition of the object to be dried R corresponding to the drying operation of the clothes selected in S2 to S9 is selected. 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 S32, it is determined that the counted cumulative number of counts is "-2". However, if the coefficient D level is set to be easily changed, the cumulative count number may be "-1". Further, if it is set that it is difficult to change the coefficient D level, the cumulative count may be a value that is "-2" or lower.

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 S17, if the user does not stop the operation before the remaining dehumidification time Y has elapsed, it is determined in step S18 whether or not the time Y calculated in step S15 has been reached.

In step S18, when the operation end condition is met (the time Y has elapsed), the process proceeds to step S19 to temporarily end the clothes drying operation. Thereafter, in step S20, the interior is moved to the standby state. In addition, the so-called standby state is a state in which dehumidification and air supply are stopped.

In step S18, when the operation end condition is not satisfied (the time Y has not elapsed), the process proceeds to step S17.

The limited time is set in the above standby state, and it is determined in step S22 whether or not a predetermined time has elapsed. When the scheduled time has elapsed in the standby state, Then, the process proceeds to step S23, 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 S21 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 judged that it is necessary to perform the drying operation again. If the operation is restarted before the process proceeds to step S23, the process proceeds to step S41.

In step S41, the calculation of the judgment count accumulation 1 as the object value of the updated setting count table selected in S2 to S9 is executed, and the flow proceeds to step S42. And the result is stored in the memory unit 7d.

Then, in step S42, 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 S43, and the level of the application level Dx of the condition of the object to be dried R corresponding to the drying operation of the clothes selected in S2 to S9 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 S44, and the additional clothes drying operation is executed.

As described above, the user resumes the operation in the standby state, thereby correcting the operation time in the extended direction.

The control flow after the above step S17 is sorted 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 judged that there is no problem in accordance with the remaining dehumidification time set. 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 is described in which the user stops the operation (that is, the time when the user operates the operation switch 8), and the user is estimated to evaluate the degree of drying of the clothes. It is regarded as an input of 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 actively input by the user. Evaluation information is also available.

In addition, when the user inputs the evaluation of the dryness by the dryness evaluation switch 11, the above (1) to (3) are respectively equivalent to the evaluation "drying". Degrees and (2) correspond to the evaluation of "Exactly" and (3) to the evaluation of "Insufficient Dryness".

According to the present embodiment, the degree of drying of the laundry as the object to be dried R is corrected based on the evaluation of the degree of drying of the clothes by the user, 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. Thereby, the user's satisfaction with the drying is used as the evaluation information and is reflected in the operation time of the drying operation of the clothes, and the drying operation of the washing material suitable for the personal preference can be performed.

In particular, the coefficient of the formula for determining the dehumidification time or the determination count value for changing the coefficient is determined in accordance with the amount of the object to be dried R and the easiness of drying (the degree of drying) of the object to be dried R. The appropriate dehumidification time is set in accordance with the amount of the object to be dried R and the easiness of drying (dryness) of the object to be dried R.

Further, in the present embodiment, the position of the object R to be dried is detected by the infrared sensor 6, but it may be performed by image processing using an optical sensor such as a camera.

Further, the ease of drying (dryness) of the object to be dried R may be obtained from the value detected by the humidity sensor 4.
