Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifying device used inside a closet, a washbasin, a kitchen, a sink, a chest or the like.

[0002]

2. Description of the Related Art Conventionally, there has been a dehumidifying device to which a heat pump has been applied, but it cannot be used in a narrow space because of its large size. Further, there was a dehumidifying device using a Peltier effect element, but there was a problem that it was not easy to use because it was necessary to lay a power cord and take out a drain hose.

On the other hand, a commercially available disposable dehumidifying device, in which a storage bag is filled with a dehumidifying agent made of calcium chloride, does not deliquesce when water is adsorbed and is in an adsorption saturated state. At that stage, the deliquescent water was discarded together with the bag.

[0004]

However, this disposable dehumidifier has a problem that the cost during use is high. On the other hand, there was also a dehumidifier that allowed the deliquescent water to drip and store it, but if the container was accidentally tilted, the deliquescent water would be spilled, which would be troublesome to handle. I had to be careful.

Further, a conventional example (Japanese Patent Laid-Open No. 48-70358) describes a fan which is blown by a fan to absorb a hygroscopic material, and the hygroscopic material is heated by a regenerating heater to be regenerated. The vapor discharged from the unit condenses on the inner surface between the partition plate forming the moisture absorbing unit and the discharge port, and this condensed water falls on the moisture absorbing unit, so that the moisture absorbing unit cannot be dried efficiently. Further, when there is a large amount of dew condensation water in the main body, the water that has fallen into the moisture absorption unit may reach the bottom portion of the main body from the lower portion of the moisture absorption unit and become submerged.

Therefore, an object of the present invention is that it is compact and easy to use and can be reused efficiently, and
An object of the present invention is to provide a dehumidifying device capable of preventing dew condensation inside the body.

[0007]

A dehumidifying device according to claim 1 is
A suction unit is formed in the lower part of the main body and a discharge port is formed in the upper part of the main unit, and a moisture absorption unit that allows the air taken in from the suction port to adsorb moisture and a heater that dries the moisture absorption unit are built into the main unit. In the above dehumidifying device, a water absorbing body that adsorbs dew condensation water generated during drying is provided inside the main body.

A dehumidifying apparatus according to a second aspect is the dehumidifying apparatus according to the first aspect, wherein the water absorbing body is provided in an air passage between a discharge side and a discharge port of the moisture absorbing unit.

[0009]

According to the dehumidifying apparatus of claim 1, when the air taken in from the suction port passes through the moisture absorption unit, the moisture contained in the air is adsorbed, and the dry air is discharged to the outside from the discharge port. The air is dehumidified. On the other hand, when removing the moisture absorbed by the moisture absorbing unit, the moisture absorbing device is taken out of the room to be dehumidified and the heater is energized to evaporate the moisture of the moisture absorbing unit and discharge it from the discharge port.

As described above, since the moisture is absorbed by the moisture absorbing unit, it is compact and easy to use. Further, since the moisture absorbing unit that has adsorbed moisture is dried by the heater, it can be reused efficiently. Furthermore, by providing a water absorber inside the main body,
Condensation water that condenses on the inner surface of the outer wall due to a temperature difference during drying can be prevented from reaching the moisture absorption unit, and the moisture absorption unit can be efficiently dried. Further, it is possible to prevent the dew condensation water from dripping outside. In addition, the water absorbing body can simultaneously adsorb the condensed water and the water contained in the vapor discharged from the moisture absorbing unit at the time of drying.

According to the dehumidifying device of claim 2, in claim 1, since the water absorbing body is provided in the air passage between the discharge side and the discharge port of the moisture absorbing unit, there is the same effect as in claim 1. .

And a power cord 16 of AC 100V having a crocodile plug on the other side is housed. Reference numeral 17 is a cord storage lid. The blower device 2 includes a propeller-shaped fan 18, a motor 19 having the fan 18 mounted on a shaft, and a motor 19
The holding frame 20 is fixed to the supporting wall 21 of the main body 1. In this blower device 2, the fan 18 is rotated by operating the motor 19,
Air is sent into the main body 1 through the suction port 5 and the filter 13 and discharged from the discharge port 6 through the moisture absorption unit 3.

The moisture absorbing unit 3 is a flat and thin box body formed by the inner wall of the double structure of the main body 1.
One of the front and back surfaces has a ventilation hole with a porosity of 50 to 60%, and the whole surface is formed by a heat dissipation lid 24 made of punching metal with a thickness of about 1 mm, which serves as a suction part, and the other has a porosity of 50 to 50%.
It has a mesh hole of 60% and the whole surface becomes an exhaust part.
The discharge plate 25 is made of 5 mm SPC punching metal. Then, the hygroscopic agent 23 whose example is silica gel is filled inside by opening the hygroscopic agent stopping lid 22. Further, a gap 26 between the heat radiation lid 24 and the outer wall of the main body 1 facing the heat radiation lid 24 communicates with the blower device 2 and the suction port 5 by a communication portion 27 as shown in FIG.
The gap 28 with the outer wall of the device communicates with the discharge port 6 through the communication part 29, and the suction port 5 → the communication part 27 → the gap 26 → the heat dissipation lid 24 of the moisture absorption unit 3 → the moisture absorbent 23 → the discharge plate 25 →
The air passage of the gap 28 → the communication portion 29 → the discharge port 6 is formed.

The heater 4 is provided in the moisture absorption unit 3, and is a heater which is made of aluminum and has a US-shaped radiator plate 30 and a positive temperature coefficient thermistor fixed to the central portion thereof by a mounting means 31 such as caulking studs. And element 32.
The lower half of the heat radiating plate 30 is formed shorter than the upper half, and fins 33 are provided on each piece in a branch shape. Then, the mounting means 31 for mounting the heater 4 at a position where the central portion of the heat dissipation plate 30 is located below the center of the heat dissipation lid 24 of the moisture absorption unit 3.
Are attached together by. When the heater element 32 is energized, heat is generated and the heat radiating plate 30 and the heat radiating lid 24 are simultaneously heated, so that the hygroscopic agent 23 can be evenly and uniformly dried throughout and the thermal efficiency can be improved. The reason for this is
It is as follows. That is, the distribution of moist air in a space such as a closet generally has higher humidity as it goes down,
In order to quickly take in such humid air into the dehumidifier, the suction port 5 is provided in the lower portion of the main body 1. in this case,
The distribution of the moist air taken in the gaps 26 in the main body 1 and the moisture absorption by the moisture absorbent 23 in the moisture absorption unit 3 are performed by the fan 1
Due to the influence of the blowing pressure of 8 on the flow path distance, a gentle moisture absorption difference from the lower bottom of the main body 1 to the upper side occurs. Therefore, the heater 4 is eccentrically arranged downward, so that the moisture absorbent 23
Can be dried almost uniformly. Further, although the moisture absorption particle size and the packing density are adjusted so that the ventilation resistance to the entire moisture absorption agent 23 in the moisture absorption unit 3 becomes substantially the same, the moisture absorption agent 23 due to dropping, vibration, etc. with use and aging The heater 4 is eccentrically arranged in consideration of prevention of uneven distribution and segregation in the downward direction. Further, when the heater 4 is energized and dried and regenerated after the moisture absorption unit 3 is full of moisture absorption, the air from the air blower 2 installed at the bottom of the main body 1 causes the heat from the heater 4 to rise into an upward airflow, thereby collecting heat and raising the temperature, and the discharge port 6 is formed.
Move in the direction of. Therefore, the heat (drying) energy in the upper portion is large and the drying tends to be accelerated, but by displacing the heater 4 below the center of the moisture absorption unit 3, the heat increasing effect can be equalized. As a result, it is possible to reduce the temperature rise of the box body near the discharge port 6 which is regulated by law, save the electric power of the heater, save the drying time, etc., and improve safety and efficiency. Furthermore, the moisture absorbent 2
The heat of evaporation (evaporation) is required for the release and drying of the water absorption in 3 and the low temperature air (indoor air) is taken in near the lower bottom of the main body 1 near the air blower 2, so that the hygroscopic agent 23 can be dried. Is disadvantageous, but the temperature of the low-temperature air can be increased by displacing the heater 4 downward.

Reference numeral 34 denotes a heat shield plate attached to the inside of the outer wall of the main body 1 facing the heat dissipation lid 24 of the moisture absorption unit 3, which has a function of reflecting the drying heat accumulated in the main body 1 and returning it to the moisture absorption unit 3 side. To do. The heat shield plate 34 is formed of an aluminum plate having a thickness of 0.1 mm. The heat shield plate 34 disperses and stirs the drying heat to make it uniform, and suppresses the temperature rise of the outer wall of the main body 1. The water absorber 35 is the main body 1 facing the discharge plate 25 of the moisture absorption unit 3.
The example is a felt (nonwoven fabric) attached to the inside of the outer wall of No. 3, which prevents dew condensation on the inner surface of the outer wall from falling to the hygroscopic agent 23 due to a temperature difference during drying, and when it is used upside down. It is installed to prevent the dripping of water.

The control means for controlling the motor 19 and the heater element 32 will be described. That is, this dehumidifying device operates the motor 19 by the storage battery 15 during dehumidification,
During charging and drying, commercial power is supplied from the power cord 16 to charge the storage battery 15 and operate the motor 19. This switching is performed by double pole double throw switches SW ₁ and SW ₂ as shown in FIG. 8, and the switch button 44 is slidably provided on the end wall of the outer wall of the main body 1. When the switch button 44 is slid from the cut position to the moisture absorption side, the two-pole double-throw switch SW ₁ opens and the two-pole double-throw switch SW ₂ closes to the contact b in FIG. Therefore, the storage battery 15 causes the control circuit 36 to operate,
The motor 19 operates. When the switch button 44 is slid from the cut position to the charging / drying side, the double pole double throw switch SW ₁ is closed and the contact a side of the double pole double throw switch SW ₂ is closed. As a result, when the plug of the power cord 16 is plugged into the outlet, the heater element 32 is supplied with power, the storage battery 15 is charged by the charging circuit G, and the motor 19 is supplied with power.

As shown in FIG. 9, the control circuit 36 detects the voltage of the storage battery 15 and outputs a signal when the voltage drops below a certain voltage to turn on the light emitting diode 37 for charging / drying prompting display, and the motor 19 A signal from a charge stimulating circuit 38 that cuts off the power supply to the motor, a timer circuit 39 that operates the motor 19 by an intermittent operation of 8 minutes on and 10 minutes off, and a sensor 40 whose resistance changes depending on humidity are input to set the resistance value. Accordingly, the moisture absorption meter 41 including the light emitting diode group 41a and its display window 41b is turned on. When the humidity is low, the upper two rows are turned on, when the humidity is medium, the central two rows are additionally turned on and the humidity is high. In this case, the lower two columns have an LED drive circuit 42 that is additionally turned on. Here, the control circuit 36
Is disposed inside the switch button 44 in the gap between the outer wall and the inner wall of the main body 1, and the light emitting diode 37 for charge and dry reminder display and the moisture absorption meter 41 are arranged in the switch button 44 on the end wall of the main body 1. It is located at the bottom. LED
The sensor 40 of the drive circuit 42 is arranged between the discharge part of the moisture absorption unit 3 and the discharge port 6, detects the relative humidity of the air blown out by the change of the adsorption force of the hygroscopic agent 23, and controls the hygroscopic state of the hygroscopic agent 23. The moisture absorption meter 41 is displayed by the circuit 36.

In FIG. 8, on the input side of the heater element 32 and the charging circuit G, a thermo switch 46 for detecting an abnormality due to thermal runaway of the heater 4 when the moisture absorption unit 3 is dried and turning off the power is connected in series. In addition to the connection, a timer 47 is connected to ensure safety by turning off the power within the dry regeneration time in order to prevent forgetting to turn off the power. The thermoswitch 46 is provided on the inner wall forming the moisture absorption unit 3 of the main body 1.

The number of rotations of the motor 19 depends on the storage battery 15
The control circuit 36 has means for controlling the number of rotations of the motor 19 so as to be small in the operation mode according to (4) and to be large in the operation mode by the AC power source through the power cord 16. Further, the capacity of the storage battery 15 and the capacity of the heater 4 are set so that the charging time of the storage battery 15 and the drying time by the heater 4 are approximately the same. This simplifies the transformer 14 and the like of the charging circuit G, balances the maintenance time by making the dry regeneration and the charging time of the storage battery 15 approximately the same, and facilitates handling and improves usability.

This dehumidifying device is used by placing it in a closet or the like. In this case, the power cord 16 is removed from the outlet. When the switch button 44 is slid to the moisture absorption side, the switch SW ₁ opens and the switch SW ₂ collapses to the contact b side as shown in FIG.
Since the motor 19 is operated via the fan and the fan 18 is rotated, the blower device 2 is in the operating state, and the wind is sucked from the suction port 5 and discharged from the discharge port 6. At this time, since the air containing moisture passes through the moisture absorption unit 3, the moisture is absorbed by the moisture absorbent 23 and the dry air is discharged from the discharge port.

Regarding the dry regeneration timing, the storage battery 15 is set to have a capacity equal to about one week required for operating the motor 19 until the moisture absorbent 23 reaches a full absorption state, and from this, the charge reminder display is displayed as a dry reminder display. Combined by means. When the battery is full, the fan 18 is stopped to save power and prevent the storage battery 15 from being over-discharged. The moisture absorption amount of the moisture absorption unit 3 is detected by the sensor 40 and displayed by the moisture absorption meter 41. When the amount of absorbed moisture is full, the switch button 44 is turned off, the dehumidifier is pushed out, and the plug of the power cord 16 is inserted into the outlet and the switch button 44
Slide to the charge / dry side. As a result, the heater 4
Heats up, the moisture absorbent 23 is heated to evaporate the moisture, and the motor 19 is operated by the AC power source to operate the blower 2, so that the air is sucked in through the suction port 5 and the evaporated moisture is discharged through the discharge port 6. Drying is performed.

According to this embodiment, when the blower 2 is operated, air is sucked into the main body 1 through the suction port 5 of the main body 1, and when the air passes through the moisture absorption unit 3, the moisture contained in the air is adsorbed. Then, the dried air is discharged to the outside from the discharge port 6. When removing the moisture absorbed by the moisture absorption unit 3, the dehumidifier is taken out of the room to be dehumidified, the blower 2 is operated, and the heater 4 is energized.
As a result, the moisture of the moisture absorbing unit 3 is evaporated and discharged from the discharge port 6.

As described above, the air containing moisture is sent to the moisture absorbing unit 3 by the air blower 2 to absorb the moisture, which is small and easy to use. In addition, the moisture absorption unit 3 that adsorbs moisture is attached to the heater 4
Since it is dried by the blower 2, it can be reused efficiently. Further, by providing the water absorbing body 35 inside the main body 1, it is possible to prevent condensed water that is condensed on the inner surface of the outer wall due to a temperature difference during drying from reaching the moisture absorbing unit 3, and the moisture absorbing unit 3 can be efficiently dried. . Further, it is possible to prevent the dew condensation water from dripping outside. Further, the water absorbing body 35 can simultaneously adsorb the condensed water and the water contained in the vapor discharged from the moisture absorbing unit 3 at the time of drying.

Regarding the location where the water absorbing body 35 is provided, it is desirable to provide it in the air passage between the discharge side of the moisture absorbing unit 3 and the discharge port 6 as in this embodiment, but it should be provided at another location. Good.
