Description

201235623 VI. Description of the Invention: [Technical Field 3 of the Invention] Field of the Invention The present invention relates to a dehumidifier. [Previously, the third aspect of the invention] The conventional dehumidifier for drying clothes is disclosed in Japanese Laid-Open Patent Publication No. 2003-42513. Hereinafter, the dehumidifier and the control method of the dehumidifier will be described with reference to the drawings. Fig. 11A is a perspective view of a conventional dehumidifier as seen from the front, and Fig. 11B is a perspective view of the dehumidifier seen from the rear, and Fig. 12 is a block circuit diagram of the dehumidifier. As shown in Figs. 11A, 11B, and 12, the dehumidifier includes a machine main body 101, a control unit 108, a temperature detecting unit 104, a humidity detecting unit 105, and an operation unit 102 that performs an operation operation of the machine. Here, the dehumidifying portion 112 and the air blowing portion 113 are provided in the machine body 101. The control unit 108 performs operation control of the dehumidifying unit 112 and the air blowing unit 113. The temperature detecting unit 108 detects the ambient temperature of the machine body 101. The humidity detecting unit 105 detects the peripheral humidity of the machine body 101. Figure 13 is a flow chart of the operation of a conventional dehumidifier. As shown in Fig. 13, when the clothes drying mode (not shown) of the operation unit operation switch is selected, the switch input is made in STEP111. Next, in STEP 112, the type of the input switch is distinguished, and when there is an input of the clothes drying switch 106, it is moved to STEP 113. Then, in STEP 113, the drying operation is started by the control unit 108, and the drying constant Dx is set. 3 201235623 The temperature and humidity detected by the temperature detecting unit 104 and the humidity detecting unit 105 are sent to the control unit 108 in the microcomputer 1 to 7 by the signal transmitting unit. The drying coefficient Tt is calculated by the control unit 1〇8 based on the detected temperature 'humidity' (STEP 116). The method for calculating the drying coefficient Tt (STEP 116) is described in detail with reference to Fig. 14 in a flow chart in which the drying coefficient Tt of the conventional dehumidifier is calculated. First, the absolute humidity Xr of the ambient gas and the total heat Ir (STEPl 21) are calculated from the detected temperature and humidity. The drying of the clothes here is reviewed on the Psychrometric Chart. Figure 15 is a humidity diagram for explaining the drying coefficient Tt of a conventional dehumidifier. In Figure 15, the ambient gas is in a normal air state. The air system in which the total heat Ir is not changed is in an enthalpy state. Since the air near the clothes when the clothes are dry becomes 100% humidity, it can be presumed to be an air state such as an ambient gas. Therefore, as shown in Fig. 14, the absolute humidity xc (steP123) in the vicinity of the laundry is calculated from the assumption that the air in the vicinity of the laundry is 100% humidity for the drying process and the total heat Ir' of the ambient gas calculated in STEP121. Next, the process proceeds to STEP 124, and the drying coefficient Tt is calculated from the absolute humidity xc near the laundry and the absolute humidity Xr of the ambient gas. The drying coefficient Tt becomes the difference between the absolute humidity Xc near the laundry and the absolute humidity Xr of the ambient gas on the humidity map of Fig. 15 (STEP 124). When the drying coefficient Tt becomes large, the transfer speed of moisture in the clothes toward the ambient gas becomes large. Therefore, when the drying coefficient Tt becomes large, the drying speed of the laundry becomes large. In the Fig. 13', based on the drying coefficient Tt (STEpU6) calculated as described above, the process proceeds to STEP 117 to determine the drying. The drying coefficient Tt is obtained for each pass of STEP 114 at a measurement interval of X minutes. The drying was judged based on the drying constant Dx in STEP 117. When the cumulative value of the drying coefficient Tt exceeds the drying constant Dx, it is determined that the laundry is dry, and the dry operation mode is stopped. Further, several kinds of drying constants Dx are prepared in advance, and are changed by the ambient gas at the start of the operation. When the laundry to be dried is hung above the air outlet of the dehumidifier 101 and the laundry drying operation is selected as described above, the dehumidification control unit 110 and the air supply control unit 111 are automatically set by the control unit 108 of the microcomputer 107. Then, the laundry drying operation mode is automatically stopped by the judgment of drying the laundry in STEP117. I. SUMMARY OF THE INVENTION In the control method of the conventional dehumidifier, the drying constant Dx which is the basis for determining the drying operation of the clothes is set at the start of the operation. However, there is a problem that the drying constant Dx cannot be adapted to the drying load at the start of the operation, such as the amount of the clothes, the moisture of the wall, the curtains, and the carpet, and the number of times of the air exchange with the outside air. Therefore, the present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a dehumidifier having a control method for determining the completion of drying of laundry in accordance with an unidentified drying load at the start of operation. Therefore, the dehumidifier of the present invention includes a dry operation mode, and includes a dehumidifying unit and a blowing unit in the machine body, a control unit that controls the operation of the dehumidifying unit and the air blowing unit, and a temperature of the peripheral temperature of the detecting device. Inspection and inspection unit, and humidity detection unit for detecting the humidity around the machine body, control unit

S 5 201235623 The drying constant initial setting control is performed, and the drying constant correction control is performed. The drying constant initial setting control is used for the first temperature detection of the temperature detecting unit and the first humidity detection value of the humidity detecting unit from the start of the dry operation mode. The drying constant Dx is determined by the dry operation mode, and the drying constant correction control uses the second temperature detection 温度 of the temperature detecting unit during the operation in the dry operation mode, the second humidity detection value of the humidity detecting unit, and the second temperature detection 値 and The drying constant Dx is corrected by at least one of the difference between the second temperature detecting enthalpy and the difference between the second humidity detecting value and the second humidity detecting value. Usually, when the clothes are dry indoors, the moisture is released into the room to increase the humidity in the room. The difference between the wet moisture released from the laundry, the wet moisture of the wall, the curtain and the carpet, the drying load of the wet moisture from the outside, and the dehumidification ability of the dehumidifier is exhibited by the change in the absolute temperature of the ambient gas. When the dehumidification is over, the absolute temperature of the ring will decrease, but the absolute temperature of the ambient gas will generally rise. However, as the drying of the clothes proceeds, the release of the wet water knife from the clothes will be less, and the dehumidification ability will be won. The dry load is much f @ The time when the dry load and the dehumidification capacity become equal change points will be longer than II and will become shorter when less. Since the drying constant Dx for determining the change point is corrected from the temperature_part_ and the detection value of the degree detecting unit in the dry operation mode, it is provided that the control for the completion of the laundry drying with higher precision in response to the drying load is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. The components having the same functions as those of the conventional dehumidifier are denoted by the same reference numerals and the detailed description is omitted. (Embodiment) FIG. 1 is a schematic cross-sectional view of a dehumidifier according to an embodiment of the present invention, and FIG. 2 is a block circuit diagram of the dehumidifier. As shown in Figs. 1 and 2, the dehumidifier includes a dehumidifying unit 112, a blowing unit 113, a control unit 1, a temperature detecting unit 104, a humidity detecting unit 105, and an operating unit in the main body 3. The control unit 1 enters 201235623 to control the operation of the dehumidifying unit 112 and the air blowing unit 113. The temperature detecting unit detects the ambient temperature of the machine body 3, and the humidity detecting unit 105 detects the peripheral humidity of the machine body 3. Further, the dehumidifier includes a dry operation mode. Fig. 3 is a flow chart showing the operation of the dehumidifier of the embodiment. As shown in Fig. 3, when the clothes drying mode (not shown) of the operation unit operation switch is selected, the switch input is performed in STEP111. Next, the type of the input switch is divided in STEP 112, and when the input of the clothes dryer switch is input, it is moved to STEP 113. Then, the drying operation is started by the control unit 1 in STEpiu, and the drying constant Dxe is set here, and the setting of the drying constant Dx for determining the completion of the drying operation mode will be described. The control unit 1 performs drying constant initial setting control, which sets the drying constant Dx initially to a predetermined standard test condition (size of the room, amount of laundry, temperature and humidity, etc.) and then seeks from the experiment. The value obtained is 0. Next, in the present invention, the correction of the drying coefficient 〇乂 value is performed. According to Fig. 14 and Fig. 13, the ambient temperature and peripheral humidity of the machine body 3 (step 115 in Fig. 13) detected from the mother test interval X minutes are obtained by taking the drying coefficient Tt (STEP 116 in Fig. 13) and drying. The constant Dx (STEP 117 of Fig. 13) was judged by drying. The drying was judged to be undried by subtracting the drying coefficient Tt from the drying constant Dx at X minutes per measurement interval, and when the subtraction value was 〇 or more, it was judged to be undried, and it was judged to be dry when the calculated value became smaller than 0. Here, the correction control of the drying coefficient Dx value of the present invention will be described using Figs. 4 to 10 . Fig. 4 is a flow chart showing the correction of the first dry constant Dx in 201235623 according to the embodiment of the present invention. First, the timer Time (STEP1) is started to start the dry operation mode, and the elapsed time is measured. Then, the temperature and humidity measured by the temperature detecting unit 1〇4 and the humidity detecting unit 105 are sent to the control unit 1 in the microcomputer 2 by the signal transmitting unit. Based on the temperature detected at the start of the dry operation mode, that is, the first temperature detected value Tempo and the first humidity detected value Rh 〇 (STEp2), the control unit 1 calculates the drying coefficient Tt0 (STEP 3), and uses each record as Initial value. Then, it enters the loop at the measurement interval of X minutes (STEP 4), and the second detected in the ηth round of the temperature detecting unit 丨〇4 and the humidity detecting unit 丨〇5 during the operation in the dry operation mode. The temperature detection value Temp(n) and the second humidity detection value Rh(n) (STEP5)' are sent to the control unit 1 in the microcomputer 2 by the signal transmission unit. The control unit 丨 calculates the absolute temperature Xr(n) (STEP6) and the calculated drying coefficient Tt (STEP7) based on the second temperature detected value Temp(6) and the second humidity detected value Rh(4) detected at the nth cycle. The drying was judged based on the drying constant Dx (STEP 8). When it is judged that it is not dry, it is judged whether or not the absolute temperature η(η) is lower than the previous data Xr(n-1) (STEP9-1), and it is returned to STEP4 when it is the same or not low. When it is low, the correction value Dh is calculated by the elapsed time Time to correct the drying constant Dx (STEPlO-1). Specifically, the correction value DH is calculated as a function of the elapsed time Time. The absolute humidity Xr(n) at the nth cycle is lower than the elapsed time Tx of the previous data x^nq). When the elapsed time is long, the correction value dh becomes a negative value in accordance with the ratio. When the elapsed time is short, the correction value DH is positive in response to its 201235623 ratio. As an example, the formula of DH=ax ( Τχ~Tjme ) is taken, and a is calculated by a fixed value. Then, the correction value DH is subtracted from the drying constant Dx to correct the drying constant Dx. When the indoor clothes are dry, the wet moisture is released into the room, and the humidity in the room rises. The difference between the drying load of the wet moisture released from the clothes, the wet moisture of the wall, the curtains and the carpet, the wet moisture from the outside, and the dehumidification ability of the dehumidifier is shown by the absolute humidity of the ambient gas; When the dehumidification capacity is exceeded, the absolute humidity Xr of the ambient gas is lowered, but usually the absolute fullness Xr of the ambient gas rises. However, as the drying of the clothes proceeds, the release of moisture from the clothes is reduced, and the dehumidification ability is more won. When the drying load is large, the time to the change point of the drying load and the dehumidification capacity becomes long, and when it is small, it becomes short. In other words, the correction is made from the dry operation mode to the time when the absolute temperature Xr(n) obtained by the second temperature detection value Temp(n) and the second humidity detection value Rh(n) starts to decrease. Dry constant Dx. Therefore, it is possible to judge the completion of the clothes drying with higher precision depending on the amount of the clothes, the wet moisture of the walls, the curtains and the carpet, and the number of times of the air exchange of the outside air. In the present embodiment, the absolute humidity Xr(n) is determined to be lower than the absolute humidity Xr(n-1) at the time of the previous measurement. However, the decrease may be determined when the continuous absolute humidity Xr(n) is decreased. Further, by determining the reduction of the absolute humidity Xr(n) by a plurality of times, it is possible to prevent erroneous judgment due to temporary interference. Next, Fig. 5 is a second drying constant Dx correction of the embodiment of the present invention.

S 201235623 - The flow chart. As shown in Fig. 5, the second drying constant Dx correction is performed from the dry operation mode to the second humidity detection value Rh (the time when the magical start is lowered. In Fig. 5, STEP 6 for calculating the absolute temperature is deleted, and The determination of the change point of the drying load and the dehumidification force is performed by the second humidity detection value humidity Rh(n) detected by the humidity detecting unit 105 at the nth cycle (STEP 9-2). The correction value DH is calculated as a function of the elapsed time Time. The second humidity detection value Rh(n) at the time of the η-under lap is lower than the elapsed time of the previous data Rh(nl). When the elapsed time is long, the ratio correction value DH is negative. In addition, when the elapsed time is short, the ratio correction value DH is positive. As an example, the formula of DH=ax(Tx—Time) is adopted. , a is calculated as a constant. Then, the correction constant DH is subtracted from the drying constant Dx to correct the drying constant 〇)^7^10-1). By this, the change point which becomes equal to the dehumidification capacity according to the relative humidity is replaced by the change point based on the absolute humidity, so that the same effect is obtained without performing complicated calculation. Next, Fig. 6 is a flow chart showing the third drying constant 〇乂 correction in the embodiment of the present invention. As shown in Fig. 6, the third drying constant Dx correction is performed by the time from the start of the dry operation mode to the start of the second temperature detection 値Rh(n) and the first temperature detection 値Tempo. In Fig. 6, in contrast to Fig. 5, only the correction value Dfi is calculated using the elapsed time Time and the first temperature detection 値 TempO to correct the difference of the drying constant Dx (STEpi 〇 2). Specifically, the correction value DH is calculated as a function of the elapsed time Time and the first temperature detection 値Tempo. The elapsed time as a reference is the difference between the elapsed time Tx when the second temperature detection 値Rh(8) is lower than the previous data Rhh-D, and the difference between the room temperature Trx and the first temperature detection 値TempO. And correct. In one example, Tx=Tx+bx (Trx~TempO) is adopted, and b is calculated by a fixed number. Based on the elapsed time Tx thus corrected, when the elapsed time is long, the ratio correction value DH becomes a negative value, and when the elapsed time is short, the ratio correction value DH becomes a positive value. As an example, j) H = ax (Tx - Time) is taken, and a is calculated as a fixed number. Then, the drying constant Dx is corrected by subtracting the correction value DH from the drying constant. As a result, the elapsed time when the drying load and the dehumidifying capacity according to the relative humidity become equal changes are long, and the drying load is long and becomes short. Further, when the room temperature is high, the time until the change point becomes short, and when the room temperature is low, the time until the change point becomes long. In this way, since the correction of the elapsed time in response to the change in the room temperature is performed, the drying load is judged more correctly. Further, although STEP9-2 (relative humidity Rh) is used as the judgment point of change, STEP9-1 (absolute humidity Xr) may be used, and the effect is not different. Next, Fig. 7 is the embodiment of the present invention. 4 drying coefficient 1 ^ correction of the flow chart. As shown in Fig. 7, the fourth drying constant 1 correction is obtained by detecting the drying coefficient TtO from the first temperature detection 値Tempo and the first humidity detection value Rh 、 and the second temperature detection 値Temp(n). The difference from the drying coefficient Tt calculated by the second humidity detection value Rh(n) is longer than the first time 値C1. In Fig. 7, with respect to Fig. 5, it is judged that the drying coefficient T t and the initial drying point are changed only at the change point where the drying load and the dehumidification capacity are equal.

S 12 201235623 The difference between the number of TMs is different from that of the fixed point C UX (STEP9-3). With ft a + ' a , tongue, and correction value DH is used as a function of the time of time to calculate the elapsed time of the drying coefficient Tt at the nth cycle and the initial drying coefficient Tt ( (fixed number). For the reference, the elapsed time Time~, the ratio correction value 1)1^ becomes a negative value. Further, the elapsed time Time is short 'the ratio correction value DH becomes a positive value. As an example, the formula of DH=axrTv τ., ~Tlme) is used, and is calculated as a fixed number. _, from the dry often ^ to correct the value 〇幵 and correct the drying constant Dx. j.L. and 6, when the drying coefficient Tt becomes larger than the initial drying coefficient Tt, the drying load is reduced from = to the inside, so the drying load is judged more accurately. -^ The fifth drying coefficient of the embodiment of the invention is corrected by the correction coefficient τ - "8th, the fifth drying constant Dx correction is made by drying the difference between the drying system and the drying system _ to exceed the drying coefficient τ_ Set negative to proceed. In Fig. 8, with respect to Fig. 7, it is judged that the dryness is equal to the change point of the drying initial force, and the difference is the value calculated by the initial drying coefficient (STEP 9-4). Different. Count. The positive value DH is the drying coefficient DX measured as a function of the elapsed time. The drying coefficient threshold is C2XTM (C2 is a fixed number) or more: the reference '(4) Japanese ime long day (four) recognition Negative value. In addition, the elapsed time w is short-lived in response to the ratio. Make a paste, take DH=ax(Tx_Time)^正正细 becomes positive ‘叫子, (4) fixed number

Dx. When the drying coefficient Tt becomes larger than the initial drying coefficient Tt, the change in the drying load in the room is small. The degree of change in the change point is small when the initial drying coefficient is one large, and the drying coefficient at the initial stage is increased by one (1) hour. Since the judgment that the change in the drying load in the room is small is corrected by the initial drying coefficient TtG, the drying load is more accurately determined. Next, Fig. 9 is a private diagram of the sixth drying coefficient 1^ correction of the embodiment of the present invention. As shown in Fig. 9, the sixth drying constant 〇\correction is obtained by the difference between the drying coefficient TtO and the drying coefficient Tt to the third time exceeding a certain value ci and the third time from the start of the dry operation mode. The detection by the temperature detecting unit 104 and the average temperature change value per unit time calculated by the temperature detection 値Temp〇 are performed. In Fig. 9, with respect to Fig. 7, the calculation of the correction value DH is performed using the elapsed time Time at this time and the temperature detection of the temperature detecting unit 104 from the nth cycle. 値 Temp(n) The average temperature change value per unit time calculated by the first temperature detection 値Temp〇 of the temperature detecting unit 104 is different from the point at which the drying constant Dx (STEpi〇_3) is corrected. Specifically, the correction value DH is calculated as a function of the elapsed time Time. The correction value DH is corrected by the elapsed time Τχ, the elapsed time Time, and the average temperature change value per unit time. Here, the elapsed time is obtained by the time difference between the drying coefficient of the first set drying constant 1 > and the initial drying coefficient Tto to a time exceeding C1 (fixed number), that is, the second time. The average temperature change value per unit time is the detected value Temp(n) of the temperature detecting unit 104 after the passage of the 201235623^ time from the start of the dry operation mode, and the first temperature detection 値Temp〇 of the temperature detecting unit 104. Calculated. As an example, TX=TX+bM(Temp(4)_Temp0)/Ti trace c} is taken, and b and c are calculated by a fixed number. When the elapsed time ra1Tx is used as the reference, the time-correction value DH becomes a negative value when the elapsed time w is long, and the ratio time correction value DH becomes a positive value when the elapsed time Time is short. As _, the formula 'a' of coffee (4), (4), and (4) is calculated by a fixed number. Then, the drying constant Dx is corrected by subtracting the correction value DH from the drying constant. Thereby, when the drying coefficient Tt becomes larger than the initial drying coefficient Tt〇, the change point of the so-called dry load in the room is shown. When the space in the room is small, the average temperature change value at room temperature tends to be large, and when the space in the room is wide, the average temperature change value at room temperature tends to be small. Since the drying coefficient Dx is corrected in response to the average temperature change value in the room, the drying load is judged more accurately. Fig. 10 is a flow chart showing the seventh drying coefficient Dx correction in the embodiment of the present invention. As shown in Fig. 10, the sixth drying constant Dx correction is such that the difference between the drying coefficient TtO and the drying coefficient Tt exceeds the second time according to the set value of the drying coefficient Tt, and from the start of the dry operation mode. The detection of the temperature detecting unit 1 〇 4 at the second time and the average temperature change value per unit time calculated by the second temperature detection 値 Temp 进行 are performed. In the first diagram, with respect to Fig. 9, only the change point is judged such that the difference between the drying coefficient Tt and the initial drying coefficient TtO is different from the point calculated by the initial drying coefficient Tt.

lS 15 201235623 Specifically, the correction value DH is calculated as a function of the elapsed time Time. The correction value DH is corrected by the elapsed time Τχ, the elapsed time Time, and the average temperature change value per unit time. Here, the difference between the drying coefficient 〇 when the first drying constant Dx is obtained and the initial drying coefficient TtO is C2xTt0 (C2 is a constant number). The average temperature change value per unit time is calculated from the first detection temperature (8) of the temperature detecting unit and the first temperature detection 値 Tempm of the temperature detecting unit 104 when the second time elapses from the start of the drying operation mode. Take as an example

Tx = TX + bx {(Temp(8)_Temp〇) / Time_c}, and c is calculated by a fixed number. Based on the Pb1Tx at the time of such correction, the elapsed time is long and the ratio is corrected to a negative value. When the elapsed time is short, the ratio is corrected to the positive value DH. As _, the formula taken :: is calculated by a fixed number. Then, the correction constant 减 is subtracted from the drying constant Dx to correct the drying constant Dx. Sea - becomes the initial drying coefficient added to the big day; the::: to the point where the drying load of the crucible becomes less. The change point is as small as =1 = when the number is increased, the change is small, and the change in the dry load at the beginning of the month is reduced. The drying constant Dx is corrected. In addition, when the 5 becomes larger, the inclination θ A 4 is the same as the average temperature of the temperature change + the temperature is changed.

The drying constant Dx is corrected by at least one of the difference between the second temperature detection 値Temp(n) and the difference between the first humidity detection 値RhO and the second humidity detection value Rh(n).
