  According to the dehumidifying apparatus of one embodiment of the present invention, the drying capacity can be increased to shorten the drying time of clothes and the like, and the defrosting capacity can be increased to shorten the defrosting time.

  That is, the heater provided between the blower outlet and the blower can increase the temperature of the air blown from the blower outlet during the warming and dehumidifying operation and shorten the drying time of clothes and the like.

  Moreover, air can be circulated inside the main body case of the dehumidifier during the de-ice operation or the like by the communication port that communicates the intake air passage and the blowout air passage. Furthermore, since the temperature of the air circulating inside the main body case can be increased by the heater, the defrosting capability can be increased and the defrosting time can be shortened.

  Moreover, it is possible to suppress air from flowing from the blowing air passage to the intake air passage through the communication port during the dehumidifying operation by the attracting rib protruding into the blowing air passage between the blower outlet and the blower. For this reason, even if there exists an opening called a communicating port, air can be blown out from a blower outlet favorably at the time of a dehumidification driving | operation.

  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
As shown in FIG. 1, the main body case 1 of the dehumidifying device 31 has a box shape, and is provided with an intake port 7 on the front side (one side) of the outer peripheral surface, and on the back side (the other side) of the top surface. The outlet 13 is provided.

  A tank 30 for storing water generated by dehumidification is provided below the dehumidifier 31.

  FIG. 2 is a cross-sectional view showing a vertical cross section of the dehumidifying device 31 in the A1-A2 cross section of FIG. In addition, in the A1-A2 cross section of FIG. 1, although the tank 30 is originally displayed, the compressor 2 in front is displayed for convenience.

  As shown in FIG. 2, the main body case 1 includes a heat pump, heat exchange means 6, and a blower 10.

  The heat pump includes a compressor 2, a radiator 3, a capillary tube 4 as an expansion means, and a heat absorber 5, which are connected in this order by a refrigerant pipe 19 to form a refrigeration cycle. This heat absorber 5 cools and dehumidifies air to be dehumidified.

  The radiator 3 and the heat absorber 5 are disposed to face each other. The radiator 3 is positioned closer to the back side (the other side) of the main body case 1, and the heat absorber 5 is positioned closer to the front side (one side) of the main body case 1.

  The heat exchanging means 6 is, for example, a cube whose lower surface is inclined, and is provided in the air path from the heat absorber 5 to the heat radiator 3 between the heat radiator 3 and the heat absorber 5.

  Specifically, the heat exchange means 6 is a cross-flow type heat exchanger, and a first heat exchange air passage 8 that is a vertical air passage and a second heat exchange that is a horizontal air passage. And an air passage 9. As shown in FIG. 3, the heat exchange means 6 is a sensible heat exchanger such as a cross flow type heat exchanger, for example, and includes a first heat transfer plate 6a and a second heat transfer plate made of resin or metal. It is formed by alternately laminating 6b.

  As shown in FIG. 2, the blower 10 is formed of a scroll-shaped casing portion 14, a motor portion 15 fixed to the casing portion 14, and a blade portion 16 that is rotated by the motor portion 15. The casing portion 14 includes a suction port 17 and a discharge port 18.

  The suction port 17 faces the radiator 3. That is, the heat absorber 5, the heat exchange means 6, the heat radiator 3, and the suction port 17 have an air path on a straight line.

  As indicated by arrows A and B by the blower 10, among the air sucked from the intake port 7, the one indicated by the arrow A is the inlet 8 a that is the upper surface of the heat exchange means 6 of the first heat exchange air passage 8. The heat exchange with the air that has already been cooled and dehumidified by the heat absorber 5 is precooled, and exits from the outlet 8b that is the lower surface of the heat exchange means 6. Then, it is cooled and dehumidified through the heat absorber 5. The cooled and dehumidified air enters the heat exchanging means 6 again from the inlet 9a of the heat exchanging means 6 of the second heat exchange air passage 9, is heated by the air flowing in from the inlet 8a, and exits from the outlet 9b to dissipate heat. It is further heated by the vessel 3 and is blown out of the machine from the blowout port 13 by the blower 10. This route is the dehumidifying air passage 11.

  In addition, the upper end part of the heat radiator 3 may be located above the upper end part of the heat absorber 5, the heat exchange means 6, and the opening / closing means 21 in the closed state. Furthermore, a part of the upper portion of the radiator 3 may face the air inlet 7. Thereby, the air indicated by the arrow B among the air sucked into the main body case 1 from the air inlet 7 by the blower 10 is blown to the air outlet 13 through the radiator 3. This is the bypass air passage 22. Thereby, a part of the air sucked into the main body case 1 from the air inlet 7 by the blower 10 is converted into the heat exchange means 6 (the first heat exchange air passage 8 and the second heat exchange air passage 9) and the heat absorber. The air can be blown to the radiator 3 without going through 5. In other words, by dividing the air into two parts, the air passing through the dehumidifying air passage 11 (arrow A) and the air passing through the bypass air passage 22 (arrow B), the amount of air blown to the heat exchange means 6 and the heat absorber 5 is dehumidified. However, since the amount of air blown to the radiator 3 can be increased while maintaining the optimum amount of air, the dehumidifying ability can be prevented from being lowered. Further, since the bypass air passage 22 is an air passage having less ventilation resistance than the dehumidifying air passage 11, an increase in the output of the blower 10 can be reduced.

  The feature of the present embodiment is that the dehumidifying device 31 further includes a heater 32 provided between the blower outlet 13 and the blower 10 and an attracting rib projecting into the blowout air passage 36 between the blower outlet 13 and the blower 10. 33 and a communication port 34 provided between the air outlet 13 and the attracting rib 33. If the air path between the air inlet 7 and the first heat exchange air path 8 is an intake air path 35, the communication port 34 forms an opening that connects the air intake path 35 and the blowout air path 36.

  FIG. 4 is a view in the vicinity of the communication port 34.

  First, the operation | movement at the time of each driving | operation of the dehumidification apparatus 31 is demonstrated using FIG.

  As shown in FIG. 6, each operation mode of the dehumidifying device 31 is provided in the compressor 2, the blower 10, the heater 32, the opening / closing means 21, and the outlet 13 according to the input signal from the operation unit. This is performed by controlling ON / OFF or opening / closing of the blown-out louver 37.

  As shown in FIG. 5, the operation modes of the dehumidifying device 31 include a dehumidifying operation, a warming dehumidifying operation, a deice operation, and an internal drying operation.

  During normal dehumidifying operation, the control means 20 turns on the blower 10, turns on the compressor 2, turns off the heater 32, closes the opening / closing means 21, and opens the blowout louver 37. Thereby, dehumidification can be performed efficiently.

  During the warming and dehumidifying operation, the control means 20 turns on the blower 10, turns on the compressor 2, turns on the heater 32, and opens the blowout louver 37. By the heater 32 provided between the blower outlet 13 and the blower 10, the temperature of the air blown from the blower outlet 13 at the time of warming dehumidification operation etc. can be raised, and drying time, such as clothing, can be shortened.

  At the time of de-ice operation in which frost adhering to the heat absorber 5 is melted, the control means 20 turns the blower 10 ON, the compressor 2 OFF, the heater 32 ON, and the blowout louver 37 closed.

  Air can be circulated inside the main body case 1 of the dehumidifying device 31 by the communication port 34 communicating the intake air passage 35 and the blowout air passage 36 during the de-ice operation or the like. Furthermore, since the temperature of the air circulating inside the main body case 1 can be increased by the heater 32, the defrosting capability can be increased and the defrosting time can be shortened.

  Here, although the opening / closing means 21 is not an essential configuration, based on the operation of the opening / closing means 21, the operation during the de-ice operation will be described in detail with reference to FIG.

  As shown in FIG. 7, during the de-ice operation, the control means 20 turns on the blower 10, turns off the compressor 2, turns on the heater 32, opens the opening / closing means 21, and closes the blowout louver 37.

  As a result, during the de-ice operation, a part of the air that has flowed from the blowing air passage 36 to the intake air passage 35 through the communication port 34 by the blower 10 is partly absorbed by the heat absorber 5 and the heat exchange means 6. 9. A first circulation air passage 70 that circulates to the blowout air passage 36 through the radiator 3 in order is formed. The first circulating air passage 70 can be opened and closed by the opening and closing means 21 connected to the control means 20. During the de-ice operation, the control means 20 opens the opening / closing means 21 so that the first circulation air passage 70 is formed. When the first circulation air passage 70 is formed, the pressure loss of the circulating air is reduced, and the air warmed by the heater 32 can be efficiently passed through the heat absorber 5. Therefore, frost adhering to the heat absorber 5 Can be efficiently dissolved. For this reason, defrosting capability can be improved and defrosting time can further be shortened.

  As shown in FIG. 8, the opening / closing means 21 may be closed during the de-ice operation. When the opening / closing means 21 is closed during the de-ice operation, the air that has flowed from the blowing air passage 36 to the intake air passage 35 through the communication port 34 by the blower 10 is sent to the first heat exchange air passage 8, the heat absorber 5, and the second A second circulation air passage 80 that circulates to the blowout air passage 36 through the heat exchange air passage 9 and the radiator 3 in this order is formed. As shown in FIG. 7, even when the opening / closing means 21 is opened during the de-ice operation, the second circulation air passage 80 exists, but most of the air circulates through the first circulation air passage 70 with low resistance. It will be.

  Next, the operation of the attracting rib 33 will be described using a schematic diagram in the vicinity of the communication port 34 of the dehumidifying device 31 shown in FIG. The left side of FIG. 9 represents a state in which the blowing louver 37 is open, and the right side represents a state in which the blowing louver 37 is closed.

  Since the dehumidifier 31 has a communication port 34 between the intake air passage 35 and the blowout air passage 36, when the blower 10 is operated, the pressure of the communication port 34 is lower than that of the blowout air passage 36. Become. That is, the portion of the communication port 34 has a negative pressure 41 and the portion of the blowing air passage 36 has a positive pressure.

  Without the attraction rib 33, even if the blowing louver 37 is open (left in FIG. 9), a part of the air flows from the blowing air passage 36 into the intake air passage 35. If it becomes like this, there exists a possibility that the dehumidification efficiency of a dehumidifier may fall.

  However, the dehumidifying device 31 of the present embodiment includes an attracting rib 33 that protrudes into the blowing air passage 36 between the blower outlet 13 and the blower 10. By having the attracting rib 33 upstream of the communication port 34, a part of the air conveyed from the blower 10 toward the blower outlet 13 is bent in the direction of the blower outlet 13 along the attracting rib 33. For this reason, air is suppressed from flowing from the blowing air passage 36 to the portion of the negative pressure 41 by the attraction rib 33, so that air flows from the blowing air passage 36 to the intake air passage 35 through the communication port 34 during the dehumidifying operation. Flow can be suppressed. As a result, even if there is an opening called the communication port 34, air can be blown out from the air outlet 13 during the dehumidifying operation.

  In addition, by adjusting the length and inclination angle of the attracting rib 33, the size of the communication port 34, etc., it is possible to satisfactorily prevent air from flowing into the negative pressure 41 portion.

  On the other hand, when the blowout louver 37 is closed as shown on the right side of FIG. 9, the air from the blower 10 toward the blowout port 13 flows through the communication port 34 to the intake air passage 35 and circulates. .

  As described above, the dehumidifying device 31 of the present embodiment particularly includes the heater 32, the attracting rib 33, and the communication port 34. Therefore, the drying capacity can be increased during the dehumidifying operation and the drying time of clothes can be shortened. The defrosting capacity can be increased and the defrosting time can be shortened.

  The heater 32 is preferably provided between the induction rib 33 and the blower 10. According to this configuration, since the heater 32 is provided upstream of the induction rib 33 and the induction rib 33 is provided upstream of the communication port 34, the heater 32 provided in the blowout air passage 36 is located near the communication port 34. It becomes difficult to disturb the air flow in the blowout air passage 36. For this reason, the air carried from the blower 10 during the dehumidifying operation flows more smoothly toward the blower outlet 13, and the air can be further suppressed from entering the intake air passage 35 through the communication port 34.

  In addition, the attracting rib 33 is preferably adjacent to the communication port 34. According to this configuration, air carried from the blower 10 during the dehumidifying operation or the like flows more smoothly toward the air outlet 13, and air further enters the intake air passage 35 through the communication port 34. Can be suppressed.

  In addition, as shown in FIG. 10, it is preferable to provide a wind pressure damper 42 at the communication port 34. In addition, the left side of FIG. 10 represents the state where the blowing louver 37 is opened, and the right side represents the state where the blowing louver 37 is closed. The wind pressure damper 42 is closed during the dehumidifying operation (left side in FIG. 10), and is open during the de-ice operation (right side in FIG. 10). According to this configuration, air carried from the blower 10 during the dehumidifying operation flows more smoothly toward the air outlet 13, and air can further be prevented from entering the intake air passage 35 through the communication port 34. .

  The wind pressure damper 42 is a non-electric wind pressure damper 42 and is preferably provided on the intake air passage 35 side of the communication port 34. According to this configuration, the wind pressure damper 42 becomes air resistance at the communication port 34, and air is prevented from entering the intake air passage 35 through the communication port 34 during dehumidifying operation without using electricity or a motor. it can.

  Moreover, as shown in FIG. 2, you may provide the temperature measurement means 38 which measures the temperature of the heat absorber 5. As shown in FIG. When the measured value of the temperature measuring unit 38 is higher than a predetermined temperature, the control unit 20 controls the dehumidifying device 31 to perform the dehumidifying operation or the warming dehumidifying operation. Further, when the measured value of the temperature measuring unit 38 is equal to or lower than the predetermined temperature, the control unit 20 controls the dehumidifying device 31 so as to perform the de-ice operation or the internal drying operation.

  Next, returning to FIG. 5, an internal drying operation which is another operation of the dehumidifying device 31 will be described. At the time of the internal drying operation, the control means 20 turns on the blower 10, turns off the compressor 2, turns on the heater 32, closes the opening / closing means 21 of the first circulation air passage 70 for a certain period of time, and opens the blower outlet 13. The blowout louver 37 is opened from the intermittently closed state.

  By closing the opening / closing means 21, a second circulation air passage 80 is formed as shown in FIG. 8, and the air heated by the heater 32 circulates. Since the inside of the dehumidifying device 31 is warmed in a wide range during this process, the water inside the dehumidifying device 31 evaporates. By circulating the warmed air to the second circulation air path 80, moisture in the inside of the heat exchange means 6 in particular will evaporate.

  After the air is circulated in the second circulation air passage 80 for a certain time, the first circulation air passage 70 is formed as shown in FIG. When the first circulation air passage 70 is formed, the pressure loss of the circulating air is reduced when the first circulation air passage 70 is formed, and the air heated by the heater 32 is efficiently supplied to the heat absorber 5. In particular, the moisture adhering to the heat absorber 5 can be efficiently evaporated.

  Further, if the blowing louver 37 is kept closed, moist air inside the dehumidifying device 31 is not discharged, and it is difficult to dry the inside of the dehumidifying device 31 sufficiently. For this reason, even when the opening / closing means 21 is opened or closed, the blowing louver 37 is opened from the intermittently closed state, and the humid air inside the dehumidifying device 31 is discharged. By doing so, the inside of the dehumidifying device 31 can be effectively dried.

  FIG. 11 is an example of a flowchart during the internal drying operation of the dehumidifier 31. The internal drying operation will be described in detail with reference to FIG.

  During the internal drying operation, the control means 20 first turns on the blower 10, turns off the compressor 2, turns on the heater 32, closes the opening / closing means 21 of the first circulation air passage 70, and closes the blowout louver 37. . This is the state shown in FIG.

Assuming that the accumulated time after starting the internal drying is the internal drying integrated time T _d , when T _d reaches T ₂ (15 minutes), the blowing louver 37 opens for T ₆ (3 minutes), and then the blowing louver. 37 is closed again.

When T _d reaches T ₁ (30 minutes), the opening / closing means 21 is opened, and the state shown in FIG. 7 is obtained.

Further, the T _d is T ₃ (30 min), blow louvers 37 are open between T ₆ (3 min), then blow louver 37 becomes closed again.

When T _d is T ₄ (45 min), blow louvers 37 are open between T ₆ (3 min), then blow louver 37 becomes closed again.

When T _d is T ₅ (60 min), the control unit 20, OFF blower 10, OFF to the compressor 2, OFF the heater 32, to close the opening and closing means 21 of the first air circulation duct 70, blowing louver 37 Is closed. This completes the internal drying operation.

  In the internal drying operation, the control means 20 may start the blowing louver to open intermittently before the opening / closing means 21 is opened. According to this configuration, the moist air inside the dehumidifying device 31 can be effectively discharged in the state shown in FIG. 8, and therefore, the water inside the heat exchanging means 6 can be effectively evaporated.

  In the dehumidifying device 31 of the present embodiment, the internal drying operation has been described, but the internal drying operation is not essential. Even if there is no internal drying operation, if there is at least a warm dehumidifying operation and a de-ice operation, the effect as the dehumidifying device 31 of this embodiment can be obtained.

  Further, although the dehumidifying device 31 includes the opening / closing means 21, the opening / closing means 21 is not essential. If the opening / closing means 21 is lost, the first circulation air passage 70 remains open without closing, but the de-ice operation or the internal drying operation can be performed.

  Further, the bypass air passage 22 is not essential. Even if the upper portion of the radiator 3 does not protrude upward and the bypass air passage 22 is not provided, the effect as the dehumidifying device 31 of the present embodiment can be obtained.

  The dehumidifying device of the present invention is expected to be used as a dehumidifying device for home use or office use.
