Description

Description: TECHNICAL FIELD The present invention relates to a dehumidifying device for use inside a closet, a washbasin, a kitchen, a sink, a chest, and the like.

[Conventional technology]

Conventionally, there was a dehumidifier that applied a heat pump, but the size of the machine was too large to be used in a narrow space.

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, the commercially available disposable dehumidifier is one in which a dehumidifying agent made of calcium chloride is filled in a storage bag, and it does not deliquesce when water is absorbed,
The deliquescent water was discarded together with the bag when the adsorption saturated state was reached.

[Problems to be Solved by the Invention]

However, this disposable dehumidifying device has a problem in that it is not possible to efficiently dehumidify the entire inside such as a push-in, even if it can be downsized.

Therefore, an object of the present invention is to provide a dehumidifying device which is small in size, convenient in use, and capable of efficiently dehumidifying even in a narrow space.

[Means for Solving the Problems]

The dehumidifying device of the present invention forms a suction port at the bottom of a box-shaped main body with a vertical width and a thin width, forms a discharge port at the upper part of the main body, and a thin moisture absorption unit for adsorbing moisture inside the main body. It is arranged. The moisture absorption unit communicates with the suction opening through a first gap between the entire front surface of the moisture absorption unit and the inner surface of the main body which faces the front surface, and the entire rear surface of the moisture absorption unit and the inner surface of the main body which faces the first rear surface. An air blower is provided below the first gap so as to communicate a second gap between the discharge port and the discharge port and blow air from the suction port to the discharge port.

[Action]

According to the dehumidifying device of the present invention, when the blower is operated,
Air is sucked into the main body through the suction port of the main body, moisture contained in the air is adsorbed when the air passes through the moisture absorption unit, and dry air is discharged to the outside from the discharge port.

In this way, the air containing moisture is sent to the moisture absorbing unit by the air blower to absorb moisture, which is compact and easy to use. Further, since the suction port is arranged in the lower part of the main body, the suction port approaches the floor surface, so that the moisture can be sucked effectively and efficiently.
Further, by providing the discharge port on the upper portion of the main body, dry light air is likely to flow upward, which facilitates discharge. Moreover, since the first gap of the thin moisture absorption unit is communicated with the suction port, the second gap is communicated with the discharge port, and the blower is provided below the first gap, the main body can be made thin. However, the contact area of air is large and the moisture absorption efficiency is good.
Since the distance to the gap is short, the ventilation resistance is small, and a large amount of air can be passed, which is efficient. In addition, the air can be uniformly and efficiently passed through the dehumidifying agent to adsorb the moisture, and even if the moisture is adhered to the futon or the like, the first gap and the second gap of the moisture absorption unit are not blocked. Does not cause deterioration of performance. Furthermore, the thinning of the dehumidifying device enables its use and installation in a narrow space.

The heater 4 is provided in the moisture absorption unit 3, and includes a heat sink 30 made of aluminum and shaped like an American character, and a heater element 32 having a positive temperature coefficient thermistor fixed to the central portion thereof by a mounting means 31 such as caulking studs. Consists of. The lower half of the heat dissipation plate 30 is formed shorter than the upper half, and fins 33 are provided on each piece in a branch shape. Then, the central portion of the heat radiating plate 30 is attached together by the attaching means 31 for attaching the heater 4 to a position lower than the center of the heat radiating lid 24 of the moisture absorbing unit 3. 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 to evenly and uniformly dry the hygroscopic agent 23 and enhance the thermal efficiency.

Reference numeral 34 is 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, and serves to reflect the drying heat accumulated in the main body 1 and return it to the moisture absorption unit 3 side. This heat shield plate 34 is formed of a 0.1 mm aluminum plate,

Reference numeral 35 denotes a water absorbent body having a felt (nonwoven fabric) attached to the inside of the outer wall of the main body 1 facing the discharge plate 25 of the moisture absorption unit 3 as an example, and the dew condensation water that condenses on the inner surface of the outer wall due to a temperature difference during drying is absorbed. In addition to preventing it from falling into the agent 23,
It is installed to prevent dripping of water when it is used upside down.

A control means for controlling the motor 19 and the heater element 32 will be described. That is, in this dehumidifying device, the storage battery 15 operates the motor 19 during dehumidification, and during charging / drying, the 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 switch shown in FIG.
SW ₁ opens and switch SW ₂ closes to contact b. For this reason,
The control circuit 36 is operated by the storage battery 15, and the motor 19
Works. When the switch button 44 is slid from the off 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 circuit 15 is charged by the charging circuit G, and the motor 19 is supplied with power.

The control circuit 36, as shown in FIG.
When the voltage of is detected and it becomes a certain voltage or less, a signal is output,
Turn on the light emitting diode 37 for charging / drying reminder display,
Input the signal of the charge stimulus circuit 38 that cuts off the power supply to the motor 19, the timer circuit 39 that operates the motor 19 by the intermittent operation of 8 minutes on and 10 minutes off, and the sensor 40 whose resistance changes depending on the humidity. Depending on the value, 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, and when the humidity is medium, the central 2
The LED driving circuit 42 additionally lights up the columns and the lower two lines additionally light up when the humidity is high. Here, the control circuit 36 is arranged inside the switch button 44 in a gap between the outer wall and the inner wall of the main body 1, and the light emitting diode 37 for charging / drying reminder display and the moisture absorption meter 41 are the end walls of the main body 1. The switch button 44 is disposed below the switch button 44. Also LED drive circuit 4
The second sensor 40 is arranged between the discharge part of the moisture absorption unit 3 and the discharge port 6 to detect the relative humidity of the air blown out by the change of the adsorption force of the adsorbent 23, and the control circuit 36 detects the moisture absorption state of the hygroscopic agent 23. It is displayed by the moisture absorption meter 41.

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, and 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.

Further, the air flow rate of the air blower 2 in the dry regeneration mode is set to be larger than the air flow rate of the air blower 2 in the dehumidification mode, that is, the operation mode. That is, in the embodiment, the voltage applied to the motor 19 by the control circuit 36 is set so that the rotation speed of the motor 19 is small in the operation mode by the storage battery 15 and is large in the operation mode by the AC power supply through the power cord 16. I am lowering.

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 of the heater 4 are approximately the same. As a result, the transformer 14 of the charging circuit G can be simplified, and the dry regeneration and the charging time of the storage battery 15 can be made approximately the same to balance the maintenance time, and the handling is easy and the usability can be improved.

This dehumidifier is used by placing it in a closet or the like. In this case, disconnect the power cord 16 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.
Causes the motor 19 to operate via the control circuit 36,
Since the fan 18 rotates, the blower device 2 is in an operating state,
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 time, the storage battery 15 is made equal to the capacity required for operating the motor 19 up to the full absorption state of the hygroscopic agent 23 for about one week, and from this, the light emitting diode 37 is used to display the charge reminder display and the dry reminder display. Can be combined with. When the battery is full, the fan 18 is stopped to save power and
19 to prevent over-discharge.

On the other hand, 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 dehumidifying device is pushed out and taken out, 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 hygroscopic agent is heated to evaporate water, and the motor 19 is operated by the AC power source to operate the blower device 2. Therefore, the wind is sucked from the suction port 5 and evaporated from the discharge port 6. Water is discharged and drying is performed.

According to this embodiment, air containing moisture is sent to the moisture absorbing unit 3 by the air blower 2 to absorb moisture, which is small and easy to use.

Further, since the suction port 5 is arranged in the lower part of the main body 1, the suction port 5
Since it approaches the floor surface, the humidity can be inhaled effectively and efficiently. In other words, the humidity distribution during close-up is such that the water near the pillars at the corners of the closet, concrete wall, etc., or the wind and rain on the north side infiltrate the water, or the water in a wetland enters the foundation and penetrates the walls. By taking out, moisture is generated and distributed on the floor surface. Therefore, the suction port 5 of the main body 1 is located on the bottom surface close to the floor surface, and has a structure capable of effectively and efficiently sucking moisture.

Further, by providing the discharge port 6 on the upper portion of the main body 1, it is easy to discharge because dry light air easily flows upward. That is, when the discharge port 6 is provided above the main body 1, the discharge of the dry air is directed upward as a light air flow, the flow of the air flow is natural, and the sending force by the air supply from below is also added, so that the flowability is good. You can get a good air flow.

Moreover, since the gap 26 of the thin moisture absorption unit 3 is communicated with the suction port 5, the gap 28 is communicated with the discharge port 6, and the blower device 2 is provided below the gap 26, the main body 1 is made thin. In addition, since the air contact area is large and the moisture absorption efficiency is good, and the distance between the gap 26 and the gap 28 is short, the ventilation resistance is small, and a large amount of air can be passed, and the efficiency is high. Moreover, the air can be evenly and efficiently passed through the dehumidifying agent 23 to adsorb moisture, and even if the moisture is adhered to a futon or the like, the gap 26 and the gap 28 of the moisture absorption unit 3 are not blocked, so that the performance is improved. Does not cause a decline. Furthermore, the thinning of the dehumidifying device enables its use and installation in a narrow space.

The dehumidifying device of the present invention is compact and easy to use because the air containing moisture is sent to the moisture absorbing unit by the air blowing device to absorb the moisture. Further, since the suction port is arranged in the lower part of the main body, the suction port approaches the floor surface, so that the moisture can be sucked effectively and efficiently. Further, by providing the discharge port on the upper portion of the main body, dry light air is likely to flow upward, which facilitates discharge. Moreover, since the first gap of the thin moisture absorption unit is communicated with the suction port, the second gap is communicated with the discharge port, and the blower is provided below the first gap, the main body can be made thin. However, since the air contact area is large and the moisture absorption efficiency is good, and the distance between the first gap and the second gap is short, the ventilation resistance is reduced and a large amount of air can be passed, resulting in high efficiency. Good. In addition, the air can be uniformly and efficiently passed through the dehumidifying agent to adsorb the moisture, and even if the moisture is adhered to the futon or the like, the first gap and the second gap of the moisture absorption unit are not blocked. Does not cause deterioration of performance. Furthermore, the thinning of the dehumidifier has an effect that it can be used and installed in a narrow space.
