Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dehumidifying device used inside closets, washrooms, kitchens, sinks, chests of drawers, and the like.

[Conventional technology]

Previously, there were dehumidifiers that utilized heat pumps, but they were too large to be used in confined spaces.

There was also a dehumidifying device using a Peltier effect element, but it was difficult to use because it required installing a power cord and taking out a drain hose.

In contrast, disposable dehumidifiers that are already commercially available have a storage bag filled with a dehumidifier made of calcium chloride, which deliquesces and disappears when it absorbs moisture.
Once the adsorption saturation was reached, the deliquescent water was discarded together with the bag.

[Problem to be solved by the invention]

However, this disposable dehumidifier has a problem in that it is expensive to use.

On the other hand, there was a dehumidifying device that dripped deliquescent water and collected it, but if the container was accidentally knocked over, the deliquescent water would spill out, making it difficult to handle.Moreover, if you hung it on a plant, it could wither, so it had to be disposed of. I had to be careful.

Therefore, an object of the present invention is to provide a dehumidifying device that is small, easy to use, and can be efficiently reused.

[Means to solve the problem]

The dehumidifying device of the present invention has a suction port for sucking in air at the bottom of the main body that has a built-in air blower, and a discharge port for blowing the air at the top of the main body, so that the air from the blower passes through and removes moisture. A heat absorbing unit is built into the main body. Further, a heater that generates heat when drying the moisture absorbing unit I is arranged to be offset downward from the center of the moisture absorbing unit I.

[Effect]

According to the configuration of this invention, when the blower is operated, air is sucked into the main body from the suction port of the main body, and when the air passes through the moisture absorption unit, moisture contained in the air is adsorbed, and dry air is discharged. It is discharged to the outside from the outlet. To remove moisture absorbed by the moisture absorption unit, take the moisture absorption device out of the room to be dehumidified, operate the blower, and energize the heater. This causes the moisture in the moisture absorption unit to bloom and is discharged from the discharge port. let

In this way, the air containing moisture is sent to the heat absorbing unit using the blower, so it is small and easy to use. Furthermore, since the moisture absorbing unit that has absorbed moisture is dried using a heater and blower, it can be reused efficiently. Further, since the heater is arranged to be offset downward from the center of the moisture absorbing unit 1, the entire moisture absorbing unit 1 can be uniformly dried.

This handle 10 makes it convenient to carry and take out the main body 1, and since the entire surface of the discharge port 6 is covered by the handle 1°, it supports hanging objects and prevents the discharge port 6 from being blocked. The shape of the discharge port 6 is such that a large number of slits are arranged in the longitudinal direction of the main body 1, and the ends of each slit extend to the front and back surfaces of the main body 1, and the thickness of the main body 1 is adjusted as shown by the first arrow. I'm trying to be able to spit it out in any direction.

The lower part of the main body 1 has two legs 1 extending in the longitudinal direction so that it can be placed on it.
1 is installed protrudingly. The suction port 5 is formed at the center of the lower part and extends to the front and back surfaces so as to straddle the leg 11 from the inside. Therefore, the wind enters the gap 12 between the legs 11 from the end of the main body 1 as shown by the arrow in FIG. 6, and also from the front and back sides. Further, a filter 13 is provided inside the suction [15].

Inside the main body 1, a double-layered bottom part is provided with an air bag W2 located inside the suction port 5, and an example of this is shown in the charging circuit G.

It is formed by a discharge plate 25 made of SPC punched metal. Then, a moisture absorbent 23 made of silica gel is filled inside with the moisture absorbent stopper lid 22 opened.

In addition, the gap 26 between the heat dissipation lid 24 and the outer wall of the main body 1 facing it communicates with the blower 2 and the suction port 5 through a communication portion 27 as shown in FIG. A gap 28 between the outer wall and the discharge port 6 communicates with the communication portion 29,
In the main body 1, an air passage is formed from the suction port 5, the continuous passage 27, the gap 26, the heat radiation lid 24 of the moisture absorbing unit 3, the moisture absorbent 23, the discharge plate 25, the gap 28, the continuous passage 29, and the discharge port 6.

The heater 4 is installed in the moisture absorption unit 3, and includes a heat dissipation plate 30 made of aluminum and shaped like an American letter, and a heater element 32, which is an example of a positive temperature coefficient thermistor fixed to the center of the heat dissipation plate 30 by a mounting means 31 such as a caulking stud. Consisting of The lower half of the heat dissipating plate 30 is shorter than the upper half, and fins 33 are provided in the shape of branches on its many pieces. The center portion of the heat sink 30 is attached to the heater 4 at a position lower than the center of the heat sink cover 24 of the moisture absorption unit 3 by means of attachment means 31. When the heater element 32 is energized, it generates heat, and the heat dissipation plate 30 and the heat dissipation lid 24 are simultaneously heated, thereby uniformly drying the moisture absorbent 23 as a whole and increasing thermal efficiency.

34 is the heat dissipation of the moisture absorption unit 3, and the main body 1 facing 124
This is a heat shield plate attached to the inside of the outer wall of the main body l, and serves to reflect the dry heat that accumulates inside the main body l and return it to the moisture absorption unit 3 side. This heat shield plate 34 is formed of a 0.1 mm aluminum plate, and aims at dispersing, stirring, and making the drying heat uniform, thereby suppressing a rise in the temperature of the outer wall of the main body 1.

Reference numeral 35 denotes a water absorbing body made of felt (nonwoven fabric) attached to the inside of the outer wall of the main body 1 facing the discharge plate 25 of the moisture absorbing unit 3, and the condensed water that condenses on the inner surface of the outer wall due to the temperature difference during drying is absorbed. This is installed to prevent water droplets from falling onto the agent 23 and to prevent water droplets from dripping when used upside down.

A control means for controlling the motor 19 and the heater element 32 will be explained. That is, this dehumidification device operates the motor 19 using the storage battery 15 during dehumidification, and operates the storage battery 15 by supplying commercial power from the power cord 16 during charging and drying.
This is to charge the battery and operate the motor 19.

As shown in FIG. 8, this switching is performed by a two-pole, double-throw switch 5W1SW2, whose switch button 44 is slidably provided on an end wall of the outer wall of the main body 1. When the switch button 44 is slid from the off position to the moisture absorption side, the eighth
At 0, the 2-pole double-throw switch SW1 opens, and the 2-pole double-throw switch SW2 closes the contact. For this reason, the storage battery 15
As a result, the control circuit 36 operates, and the motor 19 operates. When the switch button 44 is slid from the off position to the charging/drying side, the 2-pole double-throw switch sw1 closes and the contact a side of the 2-pole double-throw switch SW2 closes.

As a result, when the plug of the power cord 16 is inserted into the outlet, power is supplied to the heater element 32, the storage battery 15 is charged by the charging circuit G, and power is supplied to the motor 19.

As shown in FIG. 9, the control circuit 36 detects the voltage of the storage battery 15 and outputs a signal when the voltage falls below a certain level, lights up a light emitting diode 37 for displaying a charging/drying reminder, and energizes the motor 19. Charging reminder circuit 3 that cuts
8 and motor 1 by intermittent operation of 8 minutes on and 10 minutes off.
9 and a sensor 40 whose resistance changes depending on the humidity, the moisture absorption meter 41 consisting of a group of light emitting diodes 41a and its display window 41b is turned on according to the resistance value, and when the humidity is low, The LED drive circuit 42 has an LED drive circuit 42 in which the upper two rows are turned on when the humidity is medium, the middle two rows are additionally turned on when the humidity is medium, and the lower two rows are additionally turned on when the humidity is high. Here, the control circuit 36 is connected to the switch button 4.
A light emitting diode 3 is disposed in the gap between the outer wall and the inner wall of the main body 1 on the inside of the main body 4, and also serves as a charging reminder and a drying reminder display.
7 and the moisture absorption meter 41 are connected to the switch button 4 on the end wall of the main body 1.
It is located at the bottom of 4. Further, the sensor 40 of the LED drive circuit 42 is disposed between the discharge part and the discharge port 6 of the moisture absorption unit 3, and detects the relative humidity of the air blown out based on changes in the adsorption force of the absorbent 23, and detects the moisture absorption state of the absorbent 23. is displayed by the temperature absorption meter 41 from the control circuit 36.

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

Further, the rotation speed of the motor 19 is small when in the operation mode using the storage battery 15, and is large when the operation mode is using an AC power source through which the power cord 16 is passed. It has means for controlling.

Furthermore, 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 not only simplifies the transformer 14 and the like of the charging circuit G, but also makes the dry regeneration and charging times of the storage battery 15 approximately the same to balance the maintenance time, making it easier to handle and improve usability.

This dehumidifier is used by placing it in a closet, etc.

In this case, remove the power supply coat 6 from the outlet I. When the switch button 4-"4 is slid to the moisture absorption side, the switch sw1 opens and the switch SW2 falls to the contact side as shown in FIG.
Since the motor 19 is operated via the fan 18 and the fan 18 is rotated, the air blower 2 is put into operation, and air is sucked in through the suction port 5 and discharged from the discharge port 6. At this time, since air containing moisture passes through the moisture absorption unit 3, it is absorbed by the moisture absorption agent 232, and dry air is discharged from the discharge port.

Regarding the drying regeneration period, the capacity of the storage battery 15 is set to be equal to about one week required to operate the motor 19 until the moisture absorption agent 23 is fully absorbed, and from this point on, the charging reminder display is also used as the drying reminder display means. do. 18 fans when full
By stopping the storage battery 19, power is saved and over-discharge of the storage battery 19 is prevented.

The amount of moisture absorbed by the moisture absorption unit 3 is detected by a sensor 40 and displayed by a moisture absorption meter 41. When the amount of moisture absorption is full, the switch button 44 is turned off, the dehumidifier is taken out from the closet, the plug of the power cord 16 is inserted into the outlet, and the switch button 44 is slid to the charging/drying side. As a result, the heater 4 generates heat, the moisture absorbent is heated, and the moisture evaporates, and the AC power supply drives the motor 19.
is activated and the blowing device operates, so air is sucked in from the suction port 5 and evaporated moisture is discharged from the discharge port 6, thereby performing drying.

According to this embodiment, when the blower device 2 is operated, the main body 1
Air is sucked into the main body 1 through the suction port 5, and when the air passes through the moisture absorption unit 3, moisture contained in the air is adsorbed, and dry air is discharged to the outside through the discharge port 6. When removing moisture absorbed by the moisture absorption unit 3, the dehumidifier is taken out of the room to be dehumidified, the blower device 2 is activated, and the heater 4 is energized, thereby evaporating and discharging the moisture in the moisture absorption unit 3. Discharge from exit 6.

In this way, since the air containing moisture is sent to the moisture absorption unit 3 by the blower 2 and absorbed, it is small and easy to use. Furthermore, since the moisture absorbing unit 3 that has absorbed moisture is dried by the heater 4 and the blower 2, it can be efficiently reused. Furthermore, since the heater 4 is arranged to be offset downward from the center of the moisture absorption unit 3, the entire moisture absorption unit can be dried uniformly.
