Abstract

PROBLEM TO BE SOLVED: To provide a dehumidifier capable of improving the dehumidifying capacity of a main body as a result of improving the regeneration efficiency of a dehumidifying part. SOLUTION: A dehumidifying rotor 5 is mounted to a flange part 42 by providing a gap (D) between the surface of the dehumidifying rotor 5 and the tip part of the flange part 42 so that the dehumidifying rotor 5 may be rotated smoothly. And the width (E) of the flange part 42 is formed in the size larger by several times of the gap (D). Therefore, the resistance in the case when regenerated air flows in the direction leaking outside is large, and the regenerated air entered into the gap is bent to the air blowing direction and blown toward the dehumidifying rotor 5. That is, the quantity of the regenerated air leaked outside from the gap is remarkably reduced and a large quantity of the regenerated air can be effectively passed through the dehumidifying rotor 5, therefore the regenerated effectiveness of the dehumidifying rotor 5 can be remarkably increased, and the trouble such as deterioration of the dehumidifying capacity of the main body is not caused.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifier for adjusting humidity by removing moisture from dehumidified air sucked in from the outside and blowing dry dehumidified air to the outside.

[0002]

2. Description of the Related Art Conventionally, there has been a dehumidifier as an air conditioner for adjusting the humidity of indoor air. As is well known, a dehumidifier adjusts humidity by taking indoor air (hereinafter, referred to as dehumidified air) into a main body, releasing moisture to be removed and drying dehumidified air. .

FIG. 11 is a diagram showing a schematic configuration of a conventional general dehumidifier. In the drawing, 51 is a suction port for sucking dehumidified air from the outside, 52 is an air filter for removing dust and dirt from the dehumidified air sucked into the main body, 53
Is a dehumidifying rotor for removing moisture from passing dehumidified air, 54
Is a heat exchanger for exchanging heat between dehumidified air passing through the dehumidification rotor 53 and regeneration air shown below, 55 is an outlet for blowing out dehumidified air, 56 is a suction port for dehumidified air from the suction port 51 to the inside of the main body. Is a dehumidifying fan that generates a flow of air released from the suction outlet 55 into the air. A regeneration fan 57 for generating a flow of regeneration air circulating inside the main body;
Reference numeral 58 denotes a reproducing unit having a heater or the like for heating the reproducing air;
Is a condensing section for condensing the regenerated air heated by the regenerating section 58 and passing through the dehumidifying rotor 53.

As shown in the figure, dehumidified air sucked from a suction port 51 is blown out from an outlet 55 through an air filter 52, a condenser 59, a dehumidifying rotor 53, and a heat exchanger 54, and the regenerated air is regenerated. 58 → dehumidification rotor 53 → condenser 59 → heat exchanger 54 → regenerating part 58. In addition, the position of the dehumidifying rotor 53 where the air to be dehumidified passes (the moisture absorbing portion) is different from the position where the regenerating air passes (the regenerating portion). Is changing over time.

[0005] Further, reference numeral 60 shown in the figure denotes a water receiving tank for temporarily storing water dewed by the condenser 59, 61 a water level sensor for detecting the water level in the water receiving tank 60, and 62 a water level in the water receiving tank 60. A pump 63 for sending water is a water storage tank for storing the water sent by the pump 62. The water storage tank 63 is detachable from the main body and can be removed from the main body to discard water accumulated inside. When the water level of the water receiving tank 61 exceeds a predetermined level, the pump 62 starts operating and sends the water in the water receiving tank 60 to the water storage tank 63.

Next, the operation of the dehumidifier will be briefly described. FIG. 12 is a diagram illustrating the concept of the operation of the dehumidifier.
In the dehumidifier, the operation of the dehumidifying fan 56 sucks dehumidified air into the main body from the suction port 51, the air filter 52 removes dust and dirt from the sucked dehumidified air, and the dehumidifying rotor 53 absorbs moisture. From the outlet 55. In this manner, the dehumidifier dehumidifies indoor air by blowing out moisture to be dried by absorbing moisture when passing through the dehumidification rotor 53 from the outlet 55.

[0007] The regeneration air sent by the operation of the regeneration fan 57 is supplied to a heater provided in the regeneration section 58 by the heater 200 to 2.
After being heated to 50 ° C., it passes through the dehumidifying rotor 53. At this time, the high-temperature and dry regeneration air is supplied to the dehumidifying rotor 53.
Deprives the water of the water and becomes hot and humid air. In the dehumidifying rotor 53 from which the moisture has been deprived, the ability to absorb moisture from the air to be dehumidified is regenerated. The regenerated air that has passed through the dehumidifying rotor 53 is cooled by the dehumidified air in the condenser 59, and water (moisture taken when passing through the dehumidifying rotor 53) is condensed to form air having a temperature close to room temperature. 5
9 to the heater 58. The water condensed here is collected in the water receiving tank 60.

On the other hand, the air to be dehumidified is supplied to the dehumidification rotor 5.
3, the air is heated by the heat of the dehumidifying rotor 53. The heat exchanger 54 recovers a part of the heat from the air to be dehumidified and heats the regenerated air. Further, the regeneration air is supplied to the regeneration unit 5.
Heated by the heater No. 8, the air becomes high-temperature and dry air, passes through the dehumidification rotor 53 again, and regenerates the dehumidification rotor 53.

[0009] By rotating the dehumidifying rotor 53, the dehumidifying rotor 53 that has absorbed moisture from the air to be dehumidified.
Is continuously performed.

In the dehumidifier, the water level in the water receiving tank 60 is constantly monitored by the water level sensor 61.
When it detects that the water level has reached a predetermined level, the pump 62 is operated to send the water stored in the water receiving tank 60 to the water storage tank 63.

[0011]

However, in order to enable continuous operation of the dehumidifier, the dehumidifier rotor 53 is rotated as described above. A gap was provided between the substrate and the surface (it was arranged in a non-contact manner). In the conventional dehumidifier, the regeneration unit 58 is arranged with respect to the dehumidification rotor 53 as shown in FIG. As shown in FIG.
A flange 58b is provided around 8a. The regenerated air blown out from the outlet 58a is blown out toward the dehumidifying rotor 53 facing the outlet 58a, but a part of the regenerated air passes through a gap between the flange portion 58b and the dehumidifying rotor 53. It leaks out. For this reason, the amount of regeneration air passing through the dehumidification rotor 53 decreases (the leaked regeneration air does not pass through the dehumidification rotor 53).
There is a problem that the regeneration efficiency of the moisture absorbing ability of the dehumidifying rotor 53 is not good. If the regeneration efficiency is not good, the dehumidifying ability of the dehumidifying rotor 53 decreases with the operation of the main body. As a result, the dehumidifying ability of the main body decreases.

It is an object of the present invention to provide a dehumidifier capable of improving the dehumidifying ability of a main body by improving the regeneration efficiency of a moisture absorbing portion.

[0013]

The present invention has the following arrangement as means for solving the above-mentioned problems.

(1) Moisture from the dehumidified air passing through a first air passage connecting a suction port for sucking the dehumidified air into the main body and an outlet for blowing the dehumidified air sucked into the main body to the outside of the main body. A moisture absorbing portion for absorbing moisture is disposed, a heater having a heater, a regeneration portion for blowing regeneration air heated by the heater into the moisture absorption portion, and a condensation portion for condensing moisture of the regeneration air passing through the moisture absorption portion. Placed,
A second air passage configured to circulate the regeneration air inside the main body, wherein the regeneration unit has a flange around an outlet for blowing the regeneration air, and the flange and the moisture absorbing unit Means that a gap is provided and non-contact is arranged, and the width of the flange portion is larger than the gap.

In this configuration, after the moisture of the air to be dehumidified sucked into the main body from the suction port is absorbed by the moisture absorbing portion, the dried air to be dehumidified is blown out from the outlet. Further, by passing high-temperature regenerated air heated by a heater through the moisture absorbing section, moisture absorbed from the air to be dehumidified is deprived, and the ability of the moisture absorbing section to absorb moisture from the air to be dehumidified is regenerated. Note that the regenerated air that has passed through the moisture absorbing section is condensed in the condensing section and returned to air at a temperature close to room temperature, and is heated again by the heater before passing through the moisture absorbing section.

Further, in the present invention, the width of the flange portion provided around the outlet of the regeneration air in the regeneration section is made larger than the gap between the regeneration section and the moisture absorbing section. Thereby, the resistance received when the regenerated air blown out from the outlet of the regenerating section toward the surface of the moisture absorbing section flows in the direction of leaking outside through the gap between the regenerating section and the moisture absorbing section increases. For this reason, it is possible to suppress the amount of the regeneration air blown out from the outlet of the regeneration section toward the surface of the moisture absorbing section to leak outside through the gap between the regeneration section and the moisture absorption section. Therefore, the regeneration efficiency for the moisture absorbing portion can be improved, and as a result, the dehumidifying ability of the dehumidifier body can be improved.

(2) The width of the flange portion is such that the resistance of the regeneration air blown from the regeneration portion when passing through the moisture absorbing portion is smaller than the resistance when passing through the gap. (Claim 2).

In this configuration, the resistance received when flowing in the direction leaking to the outside from the gap between the regenerating part and the moisture absorbing part is greater than the resistance received when flowing in the direction passing through the moisture absorbing part. The amount of regeneration air leaking outside from the gap between the regeneration section and the moisture absorbing section can be suppressed.

(3) The flange portion is formed so as to protrude from the surface of the outlet of the regeneration air.

(4) The flange portion has a shape inclined toward the outlet of the regeneration air.

In this configuration, since the flange portion is formed to be inclined toward the outlet of the regeneration air, the regeneration air blown out from the regeneration section flows along the inclination. That is, the regeneration air that has entered the gap also flows toward the moisture absorbing portion, and leakage of the regeneration air from the gap can be further suppressed. Therefore, the dehumidifying ability of the main body can be further improved.

(5) A recess having a size that allows the flange portion to be positioned in a non-contact manner is formed in the moisture absorbing portion.

In this configuration, since the concave portion is formed in the moisture absorbing portion, the thickness of the moisture absorbing portion is reduced. For this reason, the resistance which regeneration air receives when flowing in the direction which passes through a moisture absorption part becomes smaller, and the leakage of regeneration air from the said clearance gap can be suppressed further.

In the dehumidifier 1 having the above-described structure, the dehumidifying rotor 5 is formed by impregnating a band-shaped sheet-like base material such as ceramic paper with a solvent in which zeolite (hygroscopic material) is dissolved and supporting the sheet-like base material. 1 to 1.5 mm height, impregnated with a solvent in which a hygroscopic material such as zeolite is dissolved

The condenser 12 is a blow-molded product using a polypropylene resin containing an antibacterial agent, is composed of a plurality of leak-free condensed fluid passage tubes, and is lightweight. In particular,
The condenser 12 is provided on the upstream side of the dehumidification rotor 5 in the first passage, and includes two condensers. This condenser 1

In the dehumidifier 1 of this embodiment, the position of the dehumidifying rotor 5 through which the air to be dehumidified and the regenerated air pass is continuously changed by driving the dehumidifying rotor 5 to rotate. Is possible. In addition,
A gap is provided between the dehumidifying rotor 5 and the regenerating unit 10, and they are arranged in a non-contact manner.

Hereinafter, the operation of the dehumidifier according to this embodiment will be described. The dehumidifier 1 starts the dehumidifying operation when the power switch arranged on the operation unit (not shown) is turned on and the operation start switch is operated in that state. At this time, if the water storage tank 18 is not attached to the apparatus main body, the dehumidifying operation is not started. In the dehumidifier 1, the operation of the dehumidifying fan 7 and the regeneration fan 13 is started. By the operation of the dehumidifying fan 7, the dehumidified air sucked into the main body from the suction port 2 is subjected to removal of dust such as dust and dirt by the air filter 4, and the dehumidifying rotor 5 absorbs moisture to become dry air. The heat is taken away by the heat exchanger 6 and blown out from the outlet 4. The dehumidifying rotor 5 is driven to rotate by a motor (not shown).

In the regeneration path, the operation of the regeneration fan 13 causes the regeneration section 10 → the dehumidifying rotor 5 → the regeneration box 11 →
Condenser 12 → heat exchanger 6 → regeneration unit 10 → dehumidification rotor 5 →
The flow of the regeneration air circulating inside the main body in the order of... The regeneration unit 10 is provided with a heater, and the regeneration air blown from the regeneration unit 10 is heated to 200 to 250 ° C. The regeneration air blown out from the regeneration unit 10 is dry air. When the high-temperature and dry regeneration air passes through the dehumidification rotor 5, moisture (mainly moisture absorbed from the air to be dehumidified) is taken by the regeneration air.

The regenerated air deprived of moisture from the dehumidification rotor 5 becomes humid air and is cooled in the condenser 12. For this reason, the moisture contained in the regeneration air is condensed inside the condenser 12. The water condensed here is collected in the water receiving tank 20. Since the regenerated air that has passed through the condenser 12 is cooled by the dehumidified air, the temperature is close to the room temperature. In the heat exchanger 6, the regenerated air is heated by the heat recovered from the air to be dehumidified which has been heated when passing through the dehumidification rotor 13. In the regenerating section 10, the regenerating air is heated to 200 to 250 ° C. by a heater, and is blown out from the outlet to the dehumidifying rotor 5 again.

In this way, the regenerative air circulating inside the main body continuously regenerates the moisture absorption capacity of the dehumidifying rotor 5. The heat recovered from the air to be dehumidified in the heat exchanger 6 heats the regenerated air. Here, the amount of the regenerated air is increased by 200 to
The energy required to warm to 250 ° C. can be reduced. That is, the running cost of the dehumidifier can be reduced.

As described in the section of [Prior Art], a gap is provided between the outlet of the regeneration air in the regeneration section 10 and the surface of the dehumidification rotor 5 in order to rotationally drive the dehumidification rotor 5. When the regeneration air blown out from the outlet of the regeneration unit 10 leaks to the outside from this gap, the amount of regeneration air passing through the dehumidification rotor 5 decreases, and the regeneration efficiency of the moisture absorption ability of the dehumidification rotor 5 decreases, resulting in Since the dehumidifying ability of the main body is reduced, the dehumidifier 1 of this embodiment has a regeneration unit 10.
A configuration is provided to suppress the regenerated air blown out from the air outlet from leaking to the outside through the gap. Less than,
This configuration will be described in detail.

FIG. 4 is a front view of a regeneration unit of the dehumidifier of this embodiment, and FIG. 5 is a diagram showing a positional relationship between the regeneration unit and the dehumidification rotor (a cross section taken along the line AA shown in FIG. 4). FIG. 6 is an enlarged view of a portion K in FIG. The reproducing unit 10 includes a case 23 containing a heater 21 and a shielding plate 22, and a case 2
3 is provided. Case 23
Is formed by drawing a stainless steel plate, and an opening 31 for taking in the regeneration air is formed on the side surface. Also,
An outlet 41 for blowing out the regeneration air is formed at the center of the case lid 24, and a flange 42 is formed around the outlet 41. The flange portion 42 has a convex shape as shown.

In the dehumidifier 1 of this embodiment, a gap (D) is provided between the surface of the dehumidifying rotor 5 and the tip of the flange 42.
Is installed. That is, the dehumidification rotor 5 and the regeneration unit 10 are not in contact with each other, and the dehumidification rotor 5 can be smoothly rotated. The width (E) of the flange portion 42 is formed to be several times as large as the gap (D). Further, the regeneration unit 10 is configured to divide the regeneration air taken in from the opening 31 by the shielding plate 22 into a first path B passing through the heater 21 and a second path C not passing through the heater 21. The shielding plate 22 has a stepped shape, and a large number of small holes are formed on the surface.

The regeneration air taken into the regeneration unit 10 from the opening 31 is supplied to the first path B and the second path B as shown in FIG.
And the air is blown toward the surface of the dehumidifying rotor 5 from the outlet 41 of the case lid 24 with the blowing direction bent by 90 degrees. Here, the regeneration air blown out toward the surface of the dehumidification rotor 5 is in a positive pressure state, and the regeneration air heated to a high temperature by the heater 21 through the first path B as shown in FIG. And flows into the gap between the flange portion 41 and the outside. On the other hand, as described above, the width (E) of the flange 42 is set to be several times the gap (D) between the surface of the dehumidifying rotor 5 and the tip of the flange 42, and the regenerated air entering the gap is directed outward. High resistance when flowing in the leak direction. For this reason, the regenerated air entering the gap flows toward the dehumidification rotor 5 with its blowing direction bent as shown by the arrow in FIG. Therefore, the amount of regeneration air leaking to the outside from the gap can be reduced, and a large amount of regeneration air can efficiently pass through the dehumidification rotor 5. Therefore, the regeneration efficiency of the dehumidification rotor 5 can be improved, and as a result, the dehumidification capability of the dehumidifier can be improved.

In particular, the width (E) of the flange 42 and the size of the gap (D) between the surface of the dehumidifying rotor 5 and the tip of the flange 42 are determined by the direction in which the regenerated air entering the gap leaks out. If the resistance received when flowing in the gap becomes larger than the resistance received when flowing in the direction passing through the dehumidifying rotor 5, most of the regenerated air entering the gap is bent in the blowing direction, and Flowing towards.
Therefore, the amount of regeneration air leaking to the outside from the gap can be significantly reduced, and a large amount of regeneration air can pass through the dehumidification rotor 5 more efficiently.

The magnitude of the resistance received when flowing in the direction passing through the dehumidifying rotor 5 varies depending on the thickness of the dehumidifying rotor 5 and the like. Considering these, the size of the gap (D) between the surface and the front end of the flange portion 42 is taken into consideration, and the dehumidification rotor 5 is more rejected than the resistance received when the regenerated air entering the gap flows outward. The resistance received when flowing in the direction of passing through is made smaller.

In the above embodiment, the flange 41
Is formed in a convex shape, but may be a planar shape as shown in FIG. However, the width (E) of the flange portion 42 and the size of the gap (D) between the surface of the dehumidifying rotor 5 and the tip portion of the flange portion 42 are determined in such a direction that the regenerated air entering the gap leaks outside. The resistance received when flowing in the direction passing through the dehumidifying rotor 5 is smaller than the resistance received when flowing.

As a result, the regeneration efficiency of the dehumidifying rotor 5 can be greatly improved as in the above embodiment,
As a result, the dehumidifying ability of the dehumidifier can be improved.

Further, as shown in FIG. 8, the shape of the flange 42 may be inclined toward the outlet 41 for blowing out the regeneration air. In this way, the regenerated air blown out from the outlet 41 and entering the gap between the surface of the dehumidifying rotor 5 and the flange 42 flows along this inclination. That is, the regeneration air that has entered the gap also flows toward the dehumidification rotor 5, and leakage of regeneration air to the outside from the gap can be further suppressed. Therefore, the regeneration efficiency of the dehumidifying rotor 5 can be further improved.

Further, as shown in FIGS. 9 and 10, a concave portion 5a is formed on the surface of the
May be inserted into and attached to the recess 5a in a non-contact manner. In this manner, by providing the dehumidification rotor 5 with the concave portion, the thickness of the dehumidification rotor 5 is reduced, and the resistance received when the regeneration air flows in the direction passing through the dehumidification rotor 5 is further reduced. Therefore, leakage of the regeneration air from the gap to the outside can be further suppressed. Therefore, the regeneration efficiency of the dehumidifying rotor 5 can be further improved.

The resistance of the regeneration air blown from the outlet of the regeneration section toward the surface of the moisture absorbing section when flowing in the direction of leaking outside through the gap between the regeneration section and the moisture absorbing section is increased. Therefore, when the air that has entered the gap flows in a direction that leaks to the outside, the air blowing direction is bent and passes through the moisture absorbing portion. Therefore,
The regeneration efficiency for the moisture absorbing section can be improved, and as a result, the dehumidifying ability of the dehumidifier body can be improved.
