  FIG. 5 is a block diagram showing the configuration of the controller 32 incorporated in the main body 1 and its periphery. In the figure, a controller 32 is provided in a microcomputer (hereinafter referred to as a microcomputer) 35 having a control means 33 and a blower rotation speed adjusting means 34 and a display / operation panel 36 (not shown) provided in the main body 1. A display unit 37 for displaying an operation state and the like and an operation unit 38 including various buttons are provided.

  As shown in FIG. 5, the control means 33 detects each temperature information from the temperature sensor 39 and the room temperature sensor 40 for detecting the temperature of the evaporator 7, an operation signal from the operation means 38, and a load current flowing through the compressor 3. Based on the detection information from the load current detection means 41, the time information of a built-in timer (not shown), and the humidity information from the humidity sensor 42 that detects the ambient humidity, A function for controlling the display of the display unit 37 and a dew condensation suppression control unit 43 are provided.

  As shown in FIG. 5, in the dew condensation suppression control means 43, a coefficient for weighting the operating time of the dehumidifier according to the humidity RH detected by the humidity sensor 42 is set for each predetermined humidity range. Storage means 44 pre-stored as set values, coefficient selection means 45 for selecting a coefficient corresponding to the detected humidity RH from a table of setting values preset in the storage means 44, and coefficient selection means 45 The operation time correction calculating means 46 for correcting the operation time by multiplying the coefficient selected according to the humidity RH by the operation time of the dehumidifier at the humidity RH (integration process), and the corrected operation time T (hereinafter referred to as the correction operation time T) The time counting means 47 that counts the corrected operation time T) and the total of the correction operation time T counted by the time measurement means 47 are determined to exceed a predetermined time (for example, 12 hours). Control of the compressor 3 and the blowers 18 and 19 based on a determination signal issued when the operation time determination means 48 and the operation time determination means 48 determine that the total corrected operation time T exceeds a predetermined time. Condensation suppression operation control means 49 is provided.

  The blower rotation speed adjusting means 34 adjusts the rotation speed of the blower 13 to, for example, either a strong air amount or a weak air amount based on a control signal from the control means 33.

  Next, the operation of the above configuration will be described. When the operation means 38 is operated to start the dehumidifying operation, the control means 33 outputs a signal for driving the compressor 3 and sends a signal for driving the blower 13 at a predetermined rotational speed to the blower rotational speed adjusting means. 34. As a result, the compressor 3 and the air blowing unit 13 are driven to start the dehumidifying operation of either the strong air amount or the weak air amount. During this dehumidifying operation, since the two-way valve 8 is closed by a control signal from the control means 33, the refrigerant compressed by the compressor 3 circulates through the cooling circuit 9 without passing through the two-way valve 8. That is, the refrigerant enters the condenser 4 from the compressor 3, where the heat in the refrigerant is released, and then enters the capillary tube 6 from the dryer 5 and is expanded. Thereafter, the refrigerant evaporates in the evaporator 7, takes heat from the evaporator 7, reduces the temperature of the evaporator 7, and returns to the compressor 3 again.

  At that time, the indoor air sucked into the main body 1 by the blower 13 touches the evaporator 7 to be cooled and dehumidified, and this cooling air is discharged from the first air outlet 16 to the outside of the main body 1 as dry air. In this case, the water adhering to the evaporator 7 (hereinafter referred to as drain water D) is dropped and dropped onto the drain pan 30 and then collected in the water storage tank 31.

  On the other hand, when the room temperature is low and frost adheres to the evaporator 7, the temperature detected by the evaporator 7 by the temperature sensor 39 decreases. The control means 33 detects the frost formation of the evaporator 7 when the detected temperature from the temperature sensor 39 is a predetermined temperature of, for example, 0 ° C. or lower for a predetermined time or longer, and the dehumidifying operation is changed to the defrosting operation. The control of the refrigeration cycle mechanism 2 is switched. Specifically, the two-way valve 8 is opened by the control means 33, and the refrigerant from the compressor 3 is sent directly to the evaporator 7 through the two-way valve 8 without passing through the condenser 4. As a result, the evaporator 7 acts to release the heat of the refrigerant and raise the temperature, thereby melting the frost attached to the evaporator 7. The refrigerant that has passed through the evaporator 7 returns to the compressor 3 again, and continues the defrosting operation until the temperature detected by the temperature sensor 39 rises.

  Further, during the dehumidifying operation, the control means 33 monitors the load state of the compressor 3 based on the detection information from the load current detection means 43. And when the load of the compressor 3 is less than a preset value, the operation | movement of the weak air quantity which makes the rotational speed of the ventilation part 13 low is performed. On the other hand, when the load of the compressor 3 is equal to or higher than the set value, the control unit 33 determines the current operating state of the air blowing unit 13 and keeps it if it is a strong air amount, and if it is a weak air amount, it imposes a burden on the compressor 3. In order to relieve, the operation is automatically switched to a high air flow operation in which the rotation speed of the blower 13 is increased.

  Thereafter, when the operation unit 38 performs an operation to stop the dehumidifying operation, the control unit 33 does not immediately stop the driving of the compressor 3 and the air blowing unit 13 but performs the same operation as the defrosting operation for a predetermined time or more. . That is, by opening the two-way valve 8 and forming the heating circulation path 10, the temperature of the evaporator 7 is raised, the water adhering to the evaporator 7 is evaporated, and the temperature detected by the temperature sensor 39 by the evaporator 7 is predetermined. For example, the refrigeration cycle mechanism 2 is controlled so as to be maintained at a temperature of 80 ° C. or higher for about 5 minutes. And when this state passes 5 minutes which are fixed time, the drive of the compressor 3 and the ventilation part 13 will be stopped as what the water | moisture content adhering to the evaporator 7 evaporated sufficiently.

Also, the air from the blower 13 is sucked inside the main body 1 is heated by touching the con den support 4, it is discharged from the second outlet 17 to the body 1 outside as hot air. As described above, the dehumidifier has a cold / hot air function capable of blowing out cold air and hot air from the first air outlet 16 and the second air outlet 17 provided separately.

  Subsequently, in the first air passage F1 through which the cool air passes in the operating dehumidifier, dew or the like adheres to a predetermined portion such as the first outlet 16 or the evaporator 7, and the dehumidifying function of the dehumidifier decreases. Dew condensation suppression control will be described.

  In this dew condensation suppression control, when the humidity RH detected by the humidity sensor 42 (for example, the humidity RH is a relative humidity) is equal to or higher than a predetermined humidity, the coefficient selection means 45 is stored in the storage means 44 in advance. A setting value corresponding to the detected humidity RH is selected from the setting values set for each humidity range, and the operation time calculating means 46 multiplies the operation time of the dehumidifier by using the set value as a coefficient (integration) The operation time is corrected. The corrected operating time T is counted by the time measuring means 47, and when it is determined that the total time of the corrected operating time T exceeds a predetermined value, a determination signal is issued from the operating time determining means 48. Based on this determination signal, the dehumidifier suppression operation control means 49 automatically stops the dehumidifier by the stop control of the compressor 3 and the blowers 18 and 19 or performs the stop control of the compressor 3 based on the determination signal. Is done.

  An example of the dew condensation suppression control will be described with reference to FIG. 6. When the humidity RH is RH ≧ 90% (step S1), the operation time is corrected by multiplying the operation time of the dehumidifier by the coefficient 2 (step S2). ).

  When the humidity RH is 90%> RH ≧ 85% (step S3), the operating time is corrected by multiplying the operating time of the dehumidifier by a coefficient 1.5 (step S4).

  Furthermore, when the humidity RH is 85%> RH ≧ 80% (step S5), the operating time is corrected by multiplying the operating time of the dehumidifier by a factor of 1.0 (step S6).

  If the humidity RH is 80%> RH ≧ 75% (step S7), the operating time is corrected by multiplying the operating time of the dehumidifier by a coefficient 0.5 (step S8).

  Further, when the humidity RH is less than 75% (step S9), it is determined that the dehumidifying function of the dehumidifier is operating normally without being affected by dew, etc., and the operating time in that case is multiplied by a coefficient 0. Since the processed correction is performed, the operation time of the dehumidifier with the humidity RH of less than 75% is not counted as the corrected operation time T by the time measuring means 47.

  Thereafter, the corrected operation time T is appropriately counted by the time measuring means 47, and it is determined whether or not the total of the corrected operation time T exceeds a predetermined time (for example, 12 hours) (step S10). When the corrected operation time T exceeds the predetermined time, stop control of the compressor 3 for automatically stopping the circulation of the refrigerant in the refrigeration cycle mechanism 2 and the blowers 18 and 19 of the blower 13 is performed (step). S11).

  Thus, when the dehumidifying function of the dehumidifier is lowered, the flow of air in the first air passage F1 is stopped by automatically controlling the stop of the compressor 3 and the blowers 18 and 19, and the first Since the low temperature of the first air outlet 16 and the evaporator 7 in the first air passage F1 is eliminated, the occurrence of dew condensation on the first air outlet 16 and the evaporator 7 in the first air passage F1 is generated. It is possible to prevent.

  In addition, although the operation | movement condition of the modification in a present Example is shown in a chart in FIG. 7, since step S1-step S10 are common with FIG. 6, detailed description is abbreviate | omitted.

  Hereinafter, although the control operation after step S10 will be described, it is determined whether the total of the corrected operation time T has exceeded a predetermined time (for example, 12 hours) (step S10), and when the corrected operation time T exceeds the predetermined time, In order to stop the circulation of the refrigerant in the refrigeration cycle mechanism 2, the stop control of the compressor 3 is performed (step S11).

  In this case, the dew condensation suppression operation control means 49 automatically performs stop control of the compressor 3 based on a determination signal issued when the operation time determination means 48 determines that the total corrected operation time T has exceeded a predetermined time. Shall. For this purpose, the compressor 3 is automatically stopped, and only the normal temperature air is blown by the first air blower 18 in the first air passage F1, so that the evaporator 7 in the air in the first air passage F1 Since the cooling due to the heat exchange is not performed and the low temperature of the first air outlet 16 and the evaporator 7 in the first air passage F1 is eliminated, the first air outlet 16 in the first air passage F1 is eliminated. It is possible to prevent the occurrence of condensation on the evaporator 7 and the like.

  Furthermore, although the operation state of another modified example in the present embodiment shown in FIG. 8 is shown in a chart diagram, steps S1 to S8 are the same as those in FIG. 6 and FIG.

  Hereinafter, although the control operation after step S9 will be described, the storage unit 44 is set with a humidity range (for example, humidity RH <70%) in which it is determined that the dehumidifying function of the dehumidifier is operating normally. It is stored in advance as a value.

  The humidity RH detected during operation of the dehumidifier is within the humidity range (hereinafter referred to as normal operating humidity) in which it is determined that the dehumidifier function of the dehumidifier stored in the storage means 44 is operating normally. If there is, the operation time corresponding to the normal operation humidity (hereinafter referred to as normal operation time) is counted by the time measuring means 47 (step S9), and it is determined that the normal operation time has continued for a predetermined time (for example, 1 hour) or more. If it is, the count of the total time of the corrected operation time T is cleared by the time measuring means 47 (step S10). Further, it is determined whether or not the total of the corrected operation time T exceeds a predetermined time (for example, 12 hours) (step S11), and when the corrected operation time T exceeds the predetermined time, the circulation of the refrigerant in the refrigeration cycle mechanism 2 is stopped. Therefore, the stop of the dehumidifier by the stop control of the compressor 3 and the air blowers 18 and 19 of the air blower 13 or the operation control of the compressor 3 is performed (step S12).

  In this case, after the dehumidifying function of the dehumidifier is reduced, when the reduced dehumidifying function is restored, the dew condensation suppression control by the dew condensation suppression control means 43 is canceled, and the dehumidifying operation is automatically continued. Switching judgment between the normal dehumidifying operation and the dew condensation suppression control is automatically performed. Therefore, the unnecessary dehumidification operation is prevented from being interrupted by the dew condensation suppression control, so that the influence on the dehumidification operation can be minimized while the automatic dew condensation suppression function is provided.

  Moreover, the opening part of each blower outlet 16 and 17 is provided with the grid | lattice body 25 formed so that the inside and outside of the dehumidifier main body 1 can be connected, and this grid | lattice body 25 is provided in the opening part of each blower outlet 16 and 17. Thus, it is possible to prevent a human body, a foreign object or the like from entering the inside of the dehumidifier body 1.

  By providing a flap 26 provided on the upper portion of the dehumidifier body 1 so that the angle of the surface of the flap body 27 can be varied with the rotation shaft 28 as an axis with respect to the blowing portion 12, each outlet 16 of the blowing portion 12 is provided. , 17 are provided so that the blowing angle of the cold air and the hot air blown out of the dehumidifier body 1 can be varied.

Further, the corrected operation time T is calculated by an integration time of the weighting coefficient corresponding to the room humidity and the operation time so far, so that it is possible to perform the operation control with good reactivity, and in the dehumidifier It is possible to improve the reliability of operation.

  Next, a second embodiment of the dehumidifier of the present invention will be described with reference to FIGS. Note that portions corresponding to those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  In the flap body 27 of the dehumidifier of the present embodiment, the flap 26 faces the inside of the main body 1 through the air outlets 16 and 17, and the surface from which the air from the air outlets 16 and 17 can contact, that is, the flap body 27. On the surface of the rear surface 50, a thin plate-like plate material 51, which is a dew condensation suppressing member made of a material excellent in thermal conductivity, is provided. For example, an aluminum plate is used as the material of the plate material 51, but other material excellent in thermal conductivity may be used.

  Further, as shown in FIG. 12, the plate member 51 is opposed to the first air outlet 16 on the back surface 50 of the flap body 27, and from the cold air contact portion 52 that can contact the cold air blown from the first air outlet 16. The hot air blown out from the second air outlet 17 is formed so as to continuously cover up to the hot air contact portion 53 with which the hot air can contact. In this case, the plate member 51 has the cold air side covering portion 54 formed so as to cover the cold air contact portion 52 on the back surface 50 of the flap body 27 and the warm air formed so as to cover the hot air contact portion 53 of the back surface 50 of the flap body 27. A side covering portion 55 and an intermediate portion 56 formed so as to connect the cold air side covering portion 54 and the hot air side covering portion 55 are provided.

  Further, as shown in FIGS. 9 to 11, in the flap body 27, one side 27 </ b> A in the longitudinal direction that is symmetrical with the rotation shaft 28 is parallel to the axial direction of the rotation shaft 28 toward the blowing portion 12. And a bent portion 57 formed by being bent. The plate member 51 is formed so as to cover almost the entire back surface 50 of the bent portion 57 in the flap body 27. In addition, the plate material 51 is not limited to covering substantially the entire back surface 50 of the bent portion 57, but covers the cold air contact portion 52 and the hot air contact portion 53 substantially uniformly on the back surface 50 of the flap body 27. If there is, the shape of the plate material 51 can be changed as appropriate. Further, the shape of the flap body 27 is not limited to the presence or absence of the bent portion 57.

  The operation of the above configuration will be described. The flap 26 is provided at the top of the dehumidifier body 1 so that the angle of the surface of the flap body 27 can be varied with the rotation shaft 28 as an axis with respect to the blowing portion 12. Thus, the blowing angles of the cold air and the hot air blown out from the respective outlets 16 and 17 of the blowing unit 12 to the outside of the dehumidifier body 1 are provided so as to be variable.

The hot air side covering portion 55 formed so as to cover is also heated like the hot air contact portion 53. Here, since the plate material 51 is an aluminum plate having excellent thermal conductivity, heat exchange is continuously performed between the cold air side covering portion 54 and the hot air side covering portion 55 via the intermediate portion 56 of the plate material 51. Is called.

  In the plate material 51, the low temperature of the cold air side coating portion 54 and the high temperature of the hot air side coating portion 55 are eliminated, and the local low temperature portion and the high temperature portion far from room temperature in the plate material 51 are eliminated, Eliminate temperature gaps. In this case, since the temperature difference of the flap main body 27 that is in close contact with the plate material 51 on the back surface 50 is also eliminated, it is possible to suppress the occurrence of condensation on the cold air contact portion 52 in the flap 26.

  Here, when the room air taken into the main body 1 passes through the evaporator 7 and is dehumidified, the moisture in the air in the first air passage F <b> 1 is removed from the evaporator 7 while passing through the evaporator 7. Adhere to the surface. Water droplets adhering to the evaporator 7 (hereinafter referred to as drain water D) are dropped onto a drain pan 30 provided at the lower portion of the evaporator 7 and then stored in a water storage tank 31.

  In this case, since the drain pan 30 is provided at a predetermined distance L from the evaporator 7, the drain pan 30 is disposed at a position not affected by the heat of the evaporator 7, the drain pan 30 itself is not cooled, and the outer surface of the drain pan 30 is the surrounding area. The dehumidification operation can be continued without causing condensation without falling below the dew point temperature of the air. Therefore, the temperature of the outer surface of the drain pan 30 is configured not to be affected by the heat of the evaporator 7, and therefore the drain pan 30 is cooled more than necessary even if it is disposed in the first space where the cold air circulates. Therefore, a dehumidifying operation can be performed without providing a heat insulating material to the drain pan 30 and without causing condensation on the drain pan 30.

  In addition, the rib 58 is provided from the bottom 30A of the drain pan 30 toward the evaporator 7 so that the air flow is inhibited from passing through the space between the evaporator 7 and the drain pan 30. Therefore, the air for dehumidification taken in from the 1st inlet 14 can pass through the evaporator 7 efficiently, and the ventilation path (1st ventilation path F1) with sufficient dehumidification efficiency is achieved, and the evaporator 7 is achieved. Therefore, the flow of the drain water D dripping from the air blower 13 can be inhibited, and the drain water D is prevented from scattering from the air outlets 16 and 17 of the air blower 13.

  As described above, in the present embodiment, the refrigeration cycle mechanism 2 that is the refrigeration apparatus having the evaporator 7 that is the evaporation portion in the main body 1 that is the predetermined portion, and the air blowing portion 13 that is the blowing means, and the drain water D generated by the evaporator 7 is provided. In the dehumidifier provided with the drain pan 30 as the water receiving portion for receiving the water, a third space 59 as a predetermined space is provided between the evaporator 7 and the drain pan 30, and the rib 58 is formed from the drain pan 30 toward the evaporator 7. As a result, the position of the drain pan 30 is separated to a position not affected by the heat of the evaporator 7, and a rib 58 is formed in a part of the third space 59 formed at that time to block the air flow. In addition, since the temperature of the outer surface of the drain pan 30 is not affected by the heat of the evaporator 7, it is not cooled more than necessary, and even if there is no heat insulating material, condensation does not occur. To allow continued operation. Further, by adding a rib 58 to the drain pan 30 in the direction of the evaporator 7, it is possible to achieve a blowing path (first blowing path F <b> 1) having a high dehumidifying efficiency while having the above-described effect, and further, the drain pan 30 is dropped from the evaporator 7. Scattering of the drain water D dripped can be prevented.

  In addition, this invention is not limited to the said Example, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, the shape of each fan may be different between the first blower and the second blower. In the first embodiment, various predetermined times (for example, 12 hours, 1 hour), each set value as a coefficient (2.0, 1.5, 1.0, 0.5, 0, etc.), each humidity range (RH ≧ 90%, 90%> RH ≧ 85%, 85%> RH ≧ 80%, 80%> RH ≧ 75%, RH <70%) and the like can be appropriately changed.
