(Embodiment 1)
FIG. 1 is a diagram showing an example of the configuration of a dehumidifier in an embodiment of the present invention.

  The dehumidifier body 1 is composed of a dehumidifying material such as silica gel, zeolite, or a polymer adsorbent that is rotationally driven by a dehumidifying rotor motor 2, and dehumidifying rotor dehumidifying that absorbs moisture and odor components contained in the passed air.

A heat exchanger 10 that cools by applying air, the regeneration fan 8, the regeneration heater 9, and the heat exchanger 10 are provided, and a regeneration process for flowing air when the regeneration fan 8 is driven is provided. 11 and a water tank 12 provided at the lower part of the heat exchanger 10, and further, a humidity sensor 13 and a temperature sensor 14 are provided in the dehumidifier body 1 to grasp the indoor temperature and humidity, and these signals are A control calculation unit 16 for receiving and controlling the dehumidifier body is provided in the body.

  As described above, the dehumidifying rotor 3 absorbs moisture from the room air by the dehumidifying material constituting the dehumidifying rotor, dehumidifies the dehumidifying rotor dehumidifying region 3b for dehumidifying the indoor air, and absorbs moisture from the dehumidifying material through the heated air. It is divided into a dehumidification rotor regeneration region 3a that repels moisture and regenerates the dehumidification material. The dehumidification rotor 3 is rotationally driven by the dehumidification rotor motor 2 and rotates in order with the dehumidification rotor dehumidification area 3b, then the dehumidification rotor regeneration area 3a, and then returns to the original dehumidification rotor dehumidification area 3b. The room air is dehumidified by repeatedly dehumidifying the room air and regenerating the dehumidifying material.

  Here, the dehumidification path 6 is configured to discharge the air sucked from the room through the heat exchanger 10 and indoors through the dehumidification rotor dehumidification region 3b of the dehumidification rotor 3 as indicated by arrows. .

  Further, the regeneration path 11 is a circulation path from the heat exchanger 10 to the regeneration heater 9 again through the dehumidification rotor regeneration region 3a of the dehumidification rotor 3 as indicated by an arrow.

An example of the temperature control configuration of the regenerative heater 9 in the present embodiment is shown in FIG. The regenerative heater 9 is configured so that the gate of a heater control triac 18 as a switching element is electrically connected to the control calculation unit 16 to control ON / OFF of the regenerative heater 9. Further, a regenerative thermistor 15 whose resistance value changes with temperature is adjacent to the regenerative heater 9, connected in series with the correction resistor 17, and electrically connected to the control calculation unit 16 so that the potential difference of the correction resistor 17 can be sampled. To do. With this configuration, the temperature of the regenerative heater 9 can be grasped. Regarding the temperature adjustment of the regenerative heater 9, a rectangular wave having a period T is applied to the heater control triac 18 by the control calculation unit 16. If the time T _ON for turning on the heater control triac 18 changes, the effective value of the voltage applied to the regenerative heater 9 also changes, so that the temperature of the regenerative thermistor 15 can be adjusted. In this embodiment, a triac is used, but the temperature can be adjusted by using a relay. Further, in the present embodiment, it is preferable that the temperature of the regenerative heater 9 can be adjusted from 0 ° C. to 400 ° C.

  Next, the configuration of the control calculation unit 16 is shown in FIG. The control calculation unit 16 receives signals from each sensor, etc., calculates the signal result, and outputs a command to each part of the dehumidifier body and the user turns on / off the dehumidifier body The unit 16b includes a display unit 16c for transmitting a driving state to the user, and a memory unit 16d for storing each parameter.

  Next, the calculation executed by the control calculation unit 16 will be described. FIG. 4 is a diagram showing the amount of moisture in the air at temperature and humidity. This data is stored in the memory unit 16d. Furthermore, the amount of moisture absorbed by the dehumidifying rotor 3 is measured in advance by measuring and storing the air inflow amount A per unit time by the air volume of the dehumidifying fan 5 and the moisture absorption efficiency X of the dehumidifying rotor dehumidifying region 3b in the memory unit 16d. That is, it becomes possible to calculate the moisture absorption amount. The calculation of the moisture absorption amount is one of the parameters necessary for obtaining the moisture storage amount of the dehumidifying rotor 3. FIG. 5 shows a flow showing the calculation of the moisture absorption amount. First, when the calculation is turned on, the temperature and humidity conditions in the room are grasped. Thereafter, the driving of the dehumidifying fan 5 is determined. If the dehumidifying fan 5 is not driven, the moisture absorption amount is determined to be zero. If it is driven, it communicates with the memory unit 16d, and reads the moisture content W in the air, the air inflow amount A per unit time and the moisture absorption efficiency X under the temperature and humidity conditions read earlier. The value obtained by multiplying these parameters is the moisture absorption amount K per unit time. In the present embodiment, the step for obtaining the parameter of the moisture absorption amount K is STEP1. Note that the air inflow amount A and the moisture absorption efficiency X per unit time of the dehumidifying fan 5 must be obtained in advance according to the configuration of the product.

  Further, in calculating the moisture accumulation amount of the dehumidification rotor 3, it is necessary to grasp the moisture separation amount in the dehumidification rotor regeneration region 3a in addition to the moisture absorption amount, so that the dehumidification rotor 3 of the dehumidification rotor 3 in advance as shown in FIG. It is necessary to measure the temperature-water separation characteristic and store it in the memory unit 16d. Further, the area and separation efficiency of the dehumidifying rotor regeneration region 3a are also measured and stored in the memory unit 16d. FIG. 7 shows a flow showing the calculation of the water separation amount of the present embodiment after grasping these. First, when the calculation is started, it is determined whether the regeneration heater 9 and the regeneration fan 8 are driven. When not driven, the water separation amount is determined to be zero. In the case of driving, the temperature of the regenerative heater 9 is read from the regenerative thermistor 15 and communicated with the memory unit 16d. The water separation amount B ′ per unit time at the previously read temperature and the area S of the dehumidifying rotor regeneration area 3a The separation efficiency Z is read from the memory unit 16d. A value obtained by multiplying these parameters is a water separation amount B per unit time. In this embodiment, the step of obtaining the parameter of the water separation amount B per unit time is referred to as STEP2.

  Next, FIG. 8 shows an operation flow in the present embodiment. First, when the operation is turned on, an operation for obtaining a moisture absorption amount K parameter in STEP 1 and a moisture separation amount B parameter in STEP 2 is executed. Thereafter, a value obtained by subtracting the moisture separation amount B per unit time from the obtained moisture absorption amount K per unit time is the moisture accumulation amount P ′ per unit time. The accumulated moisture amount P1 up to the previous time is added to this value to obtain the accumulated moisture amount P up to the present time. The process from this STEP 2 to the calculation of the moisture accumulation amount P up to the present is hereinafter referred to as STEP 3. Note that P1 during initial use is set to zero. If the value of the moisture accumulation amount P up to now is equal to or less than the minimum accumulation amount L, the heater output is lowered. If it is not less than the minimum accumulation amount L, it is determined whether or not it is not less than the high accumulation amount G. If less than the high accumulation amount G, the calculation from STEP1 is performed again. If it is equal to or greater than the high accumulation amount G, it is determined that the current moisture accumulation amount P of the dehumidifying rotor 3 is very large, the output of the regeneration heater 9 is increased, and STEPs 1 to 3 are executed. Thereafter, it is determined again whether or not it is higher than the high accumulation amount G. If it is higher than the high accumulation amount G, the heater output is increased again and the above operation is repeated. If it is less than the high accumulation amount G, the output of the regenerative heater 9 is decreased and the calculation from STEP1 is performed again. It should be noted that, after increasing the regeneration heater output, the process from executing STEP 1 to STEP 3 to determining the value of P is referred to as STEP 4 below. By performing these steps, it is possible to suppress the heater output with the minimum necessary power. Note that the parameters of the minimum accumulation amount L and the high accumulation amount G of the present embodiment are set so that the absorption efficiency of the dehumidification rotor 3 does not become a problem with respect to the minimum accumulation amount L, and the high accumulation amount G has an absorption efficiency. Set at the value just before the drop.

(Embodiment 2)
The configuration in the present embodiment will be described in the case where the air volume of the dehumidifying fan is controlled in the first embodiment. First, in the present embodiment, the rotational speed of the dehumidifying fan motor 4 can be changed. In order to do this, it is preferable to use a DC motor and to be able to control the rotational speed stepwise by the PWM method or the like. The configuration of the present embodiment is the same as the configuration except that the air volume of the motor of the dehumidifying fan can be changed, and the description thereof will be omitted.

  FIG. 9 is a flowchart showing the calculation method of the present embodiment.

  In the operation procedure, first, when the operation is turned on, the calculation of STEP1 and STEP2 is executed. Thereafter, a value obtained by subtracting the moisture separation amount B per unit time from the obtained moisture absorption amount K per unit time is the moisture accumulation amount P ′ per unit time. The accumulated moisture amount P1 up to the previous time is added to this value to obtain the accumulated moisture amount P up to the present time. The process from this STEP 2 to the calculation of the moisture accumulation amount P up to the present is hereinafter referred to as STEP 3. Note that P1 during initial use is set to zero. If the value of the moisture accumulation amount P up to now is equal to or less than the minimum accumulation amount L, the heater output is lowered. If it is greater than or equal to N, it is determined whether or not the accumulated amount is greater than or equal to G. If it is less than the high accumulation amount G, the calculation from STEP1 is performed again. If it is equal to or greater than the high accumulation amount G, it is determined that the current moisture accumulation amount P of the dehumidifying rotor 3 is very large, the output of the regeneration heater 9 is increased, and STEPs 1 to 3 are executed. Thereafter, it is determined again whether or not the value of the moisture accumulation amount P is equal to or greater than the high accumulation amount G. If it is equal to or less than the high accumulation amount G, the output of the regenerative heater 9 is decreased and the process returns to STEP1. If the accumulated amount is not less than G, it is determined whether the output of the regenerative heater 9 is maximum. If not, the heater output is increased again and the above operation is repeated. If it is the maximum, the output of the dehumidifying fan 5 is reduced, and the amount of water flowing into the dehumidifying rotor is reduced, thereby improving the efficiency of the regenerating work of the dehumidifying rotor 3. Thereafter, the operations of STEP 1 to 3 are performed, and it is determined whether or not the value of the moisture accumulation amount P is higher than the high accumulation amount G again. The process from the output reduction of the regeneration fan to the execution of STEPs 1 to 3 and the determination of the water accumulation amount P is hereinafter referred to as STEP5. If the water accumulation amount P is determined to be G or more in STEP5, the STEP5 process is executed again. If it is less than the high accumulation amount G, the output of the regeneration fan is increased, and then the heater output is decreased and the process returns to STEP1. By performing this operation, it is possible to improve the efficiency of the recovery operation when the recovery of the dehumidifying rotor 3 is not in time. In addition, when the specification is such that the air flow changes, the air inflow amount A per unit time area by the dehumidifying fan 5 in STEP 1 also varies, so the air inflow amount A ′ value per unit time area for each air volume is measured, Must be stored in memory.

(Embodiment 3)
Since the basic configuration of the present embodiment is the same as that of the first embodiment, description thereof is omitted.

It is a figure at the time of dividing the dehumidification rotor 3 into N equally as shown in FIG. The uppermost surface at the initial position when the dehumidifier body is activated is set as S ₁ and is named S ₂ , S ₃ ... _SN in the clockwise direction.

  In the present embodiment, the water accumulation amount for each surface divided into N is calculated. At that time, the moisture absorption amount for each surface is calculated by calculating STEP 1 in Embodiment 1 per unit area, that is, the air inflow amount per unit area. Similarly, since the water separation amount in the regeneration region is calculated per unit area, B ′ × Z is the separation amount per unit area.

  FIG. 11 is a flowchart showing the calculation in the present embodiment.

First, in this embodiment, the dehumidification rotor 3 is divided into 150 equal parts, and the dehumidification rotor makes one rotation in 60 seconds, and after 60 seconds, it returns to the book position. That is, in the example of the present embodiment, the unit time is calculated as 60/150 seconds. S _N represents each fixed coordinate, and T _N represents the coordinate after movement. That is, the position of the dehumidifying rotor is initially set to the initial position when the dehumidifying dryer is first started. Therefore, the initial value is T ₁ for the position at S ₁ , and S when the unit time has elapsed N times. _{The one} located at the position of ₁ is moved to the position of S _N , but the position as a parameter for representing the coordinates after the movement is defined as T _N. For example, those when the unit time has elapsed four times was in the position of S ₁ is T _4, and the thus came to the initial position of S ₄ is positionally. First, the variation coefficient in this block diagram is only _N in TN. First, when the dehumidifying dryer is started for the first time, S _N = T _N. Next, it is determined whether or not the N parameter of T _N is 151. In other words, since T ₁ is adjacent to T ₁₅₀ , conversion is performed so as to become T ₁ when T ₁₅₁ is reached. If the value of N is 150 or less, it is determined whether the value of N of T _N is in the range of 10-80. This is because the section of S ₁₀ to ₈₀ is the dehumidifying rotor dehumidifying region 3b in the present embodiment, that is, moisture is absorbed from the indoor air during this section, so that the moisture absorption amount can be calculated. Since the amount of accumulated moisture in this section only increases, the calculation method is to add the amount of moisture absorption to the previous amount of accumulated moisture. After these calculations, the number of N in T _N is counted by 1, and the process returns to the determination of N = 151 in T _N again. Further, if the range value of 10 to 80 of N T _N, then the value of N T _N determines whether the range of 90 to 120. This is because the section of S ₉₀ to ₁₂₀ in the present embodiment is the dehumidifying rotor regeneration area 3a, that is, the moisture is separated by the regeneration heater 9 during this section, so the amount of moisture separation can be calculated. Since the water accumulation amount in this section is only reduced, the calculation method is to subtract the water separation amount from the previous water accumulation amount. Further, since the moisture accumulation amount at the start of the dehumidifying dryer is 0, when the dehumidification rotor regeneration area 3a is in the initial state, it is calculated as 0 instead of being a negative value during the movement of this section. Thereafter, after these calculations, the number of N in T _N is counted by 1, and the process returns to the determination of N = 151 in T _N again. Incidentally, if the value of N T _N is outside the range of 90 to 120 is determined not to contain even dehumidification rotor dehumidification region 3b also dehumidification rotor reproducing area 3a, the water accumulation amount is unchanged, T _N the number of N 1 counted in, again, back up to the determination of T _N of N = 151. In this way, the water accumulation amount can be calculated more accurately by executing each part. In the present embodiment, the dehumidification rotor 3 is divided into 150 equal parts, but the number of divisions can be changed.

  Next, a method of controlling the regenerative heater 9 will be described after grasping the moisture absorption amount for each part. The heater temperature is adjusted based on the average value of the moisture accumulation amount of each portion existing in the dehumidification rotor regeneration region 3a obtained by the calculation method of FIG. Since these operation steps are the same as those in FIG. Thus, it becomes possible to calculate more accurately by finely dividing the dehumidifying rotor 3 and calculating the moisture accumulation amount.

Also, when the user turns off the power during these calculations, the state immediately before turning off is stored in the memory unit 16d, and when the power is turned on again, the state before turning off is read and restarted. It can also be a specification that can. In that case, in the operation in FIG. 11, at a timing of 1 counts the number of N in T _N, the moisture accumulation of the dehumidifying rotor 3 may be added a step that stores for each section. By doing in this way, the calculation which can respond also to a user's ON / OFF is attained.

  The calculation method of the present invention can be used not only for the dehumidification rotor composed of decicount and silica gel, but also for the calculation of the accumulated amount of a filter that collects dust and odors.
