Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifier for removing moisture from indoor air, and more particularly to a dry dehumidifier using a moisture absorber.

[0002]

FIG. 23 is a schematic view showing a conventional dehumidifier. The indoor air is taken into the dehumidifier 1 through the moisture absorption path 7 by the blower 4 as the air for moisture absorption, and cools the condenser 3 through one path 3a of the condenser 3 having two paths. Thereafter, the moisture is absorbed by the moisture absorber through the moisture absorber 2a of the moisture absorber 2 having a rotating body (not shown) filled with a moisture absorber made of zeolite or the like, and discharged to the outside of the dehumidifier 1. The regeneration air taken into the dehumidifier 1 through the regeneration path 8 by the blower 6 is heated by the heater 5 and passes through the regeneration section 2b of the moisture absorber 2 to raise the temperature of the moisture absorbent containing moisture. Then, the moisture absorbed from the moisture absorbent is removed to regenerate the moisture absorbent.

[0003] The regenerated moisture absorber moves to the moisture absorbing portion 2 a by the rotation of the moisture absorber 2 in the direction of the arrow A, and absorbs moisture from the moisture absorbing air passing through the moisture absorbing path 7 again. The high-temperature and high-humidity regeneration air that has taken water from the moisture absorber and passed through the moisture absorber 2 passes through the other passage 3b of the condenser 3 and is cooled by the above-described moisture absorption air. The water contained in the regeneration air is condensed and stored in the water storage tank 10, and the regeneration air is discharged outside the dehumidifier 1. Further, as shown in FIG. 24, there is a case where a closed circuit is configured such that the regeneration air after passing through the condenser 3 is introduced into the heater 5, and only the regeneration air is replenished from outside the room.

The moisture absorber 2 is shown in FIG.
The rotating body 21 provided in the outer frame 28 is connected to a motor 25 by a belt 26, and is supported by a bearing 27 to rotate. The rotating body 21 is covered with a support frame 24 so as to be hollow, and the inside thereof is filled with a moisture absorbing body 22. The air for reproduction in the reproduction path 8 is formed so as to pass through the reproduction section 2b (see FIG. 23) in the direction of arrow B.

The heater 5 is connected to the moisture absorber 2 in the regeneration path 8.
26 (a) and 26 (b) show a top view and a front view, in which a curved electric heating element 5a is arranged facing the reproducing section 2b.

[0006]

In the dehumidifier having such a configuration, since the regeneration path 8a after passing through the condenser 3 reaches the dew point in FIGS. 23 and 24, dew condensation easily occurs and water leakage occurs. This requires a means for collecting water droplets and measures to prevent mold, and this has been a factor in increasing costs. Further, the heat of the heater 5 is released into the room together with the heat of adsorption when moisture in the air is adsorbed by the moisture absorbing body 22 (see FIG. 25) and the heat of condensation when moisture in the regeneration path is condensed by the condenser 3, and Is increased, which may cause discomfort to the user.

The regeneration section 2 of the moisture absorber 2 shown in FIG. 23 and FIG.
At b, the regeneration air heated by the heater 5 uniformly passes through the entire regeneration section 2b. Hygroscopic body 2
2 (see FIG. 25) is heated by the passing regeneration air to release moisture, and the regeneration air absorbs the moisture and is sent from the moisture absorber 2 to the condenser 3.

The moisture absorbing body 22 that has released the moisture is the rotating body 2
1 (see FIG. 25), the heat receiving area (regeneration unit 2)
Move from b) to the heat radiation area (moisture absorbing section 2a). At this time, since the temperature of the moisture absorbent 22 has already been raised by the regeneration air heated by the heater 5, the temperature of the moisture absorbent 22 near the regeneration section 2b also increases in the heat radiation area (the moisture absorption section 2a), and this heat is absorbed. There is room for the effective use of this released heat as well as raising the temperature inside the room by being released into the room by the use air.

The outer peripheral portion 10 of the regenerating section 2b in the moisture absorber 2
3 (see FIG. 26) has a larger amount of regeneration air than the inner peripheral portion 104 (see FIG. 26). Therefore, if the electric heating element 5a of the heater 5 arranged facing the regeneration section 2b is formed uniformly, The temperature of the outer peripheral portion 103 is lower than that of the inner peripheral portion 104. For this reason, the regeneration air causes a temperature difference between the outer peripheral portion 103 and the inner peripheral portion 104, thereby deteriorating the regeneration efficiency.
Was consuming power.

In FIG. 26, the regeneration air heated by the electric heater 5a of the heater 5 enters the regeneration section 2b, and the heated regeneration air passes through the moisture absorber 22 (see FIG. 25). 22 is heated to release the contained water. The temperature of the regeneration air behind the electric heating element 5a and the electric heating element 5
Since the way of contact of the regeneration air in contact with the electric heating element 5a is different from the temperature of the regeneration air behind the gap 5b between the gaps a, the air temperature is different, and a temperature difference occurs.

Since the electric heating element 5a is disposed substantially along the circumferential direction of the moisture absorber 2, even if the rotating body 21 (see FIG. 25) rotates, any point in the rotating body 21 has the same heater. 5
(For example, the point behind the electric heating element 5a is
Similarly, even if 1 rotates, it is located behind the electric heating element 5a), and the manner of contact between the electric heating element 5a and the air for regeneration does not change much. For this reason, the moisture absorbent 22 in the regeneration section 2b
There will be a temperature difference in the temperature of the regeneration air that enters. Therefore, due to the temperature difference of the regeneration air, the regeneration unit 2
b, the regeneration efficiency deteriorates, and the temperature of the heater 5 is set to an unnecessarily high temperature in order to increase the regeneration efficiency.

Since the condenser 3 is made of metal, it is heavy in weight, and its shape is uneven, rust is generated by dew condensation water, holes are formed, and water leakage occurs. Costly. In addition, as shown in FIG. 25, the moisture absorber 2 expands and contracts due to the heated regeneration air and the radiant heat of the heater 5 disposed close to the air. The support frame 24 of the rotating body 21 that rotates inside the moisture absorbing body 2 is thermally deformed by expansion and contraction due to heat, and comes into contact with the outer frame 28 to cause a failure such that the rotating body 21 does not rotate.

An object of the present invention is to provide a dehumidifier capable of improving power-saving efficiency to reduce power consumption and suppressing a rise in room temperature to obtain a comfortable environment.

Another object of the present invention is to provide a highly-reliable dehumidifier which realizes rust prevention, corrosion prevention and prevention of germ propagation by saving space and weight and reducing costs. I do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. 1 to 22, the same members as those in the conventional example are denoted by the same reference numerals. FIG. 1 shows a schematic view of the dehumidifier of the first embodiment. The difference from the conventional example (see FIG. 23) is that a heat exchanger 9 for performing heat exchange between the high-temperature and high-humidity regeneration air that has passed through the moisture absorber 2 and the regeneration air that has passed through the condenser 3 is provided. I have.

In such a configuration, the regeneration path 8 passes through the condenser 3 in the open circuit dehumidifier 1 and reaches the dew point such that the regeneration air after passing through the condenser 3 is discharged into the room. The temperature of the regeneration air that is present is raised by exchanging heat with the high-temperature and high-humidity regeneration air that has passed through the moisture absorber 2, so that dew condensation on the regeneration path 8 c after the heat exchanger 9 can be prevented.

FIG. 2 is a schematic view of a dehumidifier according to a second embodiment. According to the figure, the case where the regeneration path 8 for passing the regeneration air after passing through the condenser 3 into the heater 5 is a closed circuit is configured similarly to the first embodiment (see FIG. 1). With this configuration, as in the first embodiment, it is possible to prevent dew condensation on the regeneration path 8c after the heat exchanger 9, and to reduce the temperature of the regeneration air (regeneration path 8a) entering the heater 5. Since the heater 5 can be raised in advance, the power consumption of the heater 5 can be reduced.

Further, the air for regeneration (regeneration path 8b) entering the heat exchanger 9 is taken in from the room, and the air for regeneration (regeneration path 8c) after passing through the condenser 3 is discharged to the outside of the dehumidifier 1. When a circuit is used, the power consumption of the heater 5 can be reduced in the same manner as described above.

Next, a dehumidifier according to a third embodiment will be described with reference to FIG. According to the figure, in the recovery unit 2bb adjacent to the regeneration unit 2b of the moisture absorber 2 and in the rotation direction of the rotating body 21 (see FIG. 25) inside the moisture absorber 2, the moisture absorber 22 ( (Refer to FIG. 25). A branch path 7a is provided to branch from the moisture absorption path 7 so as to pass through the collecting section 2bb.
The heat of bb is recovered by the moisture absorbing air passing through the branch path 7a, and the heat is exchanged with the regeneration air before entering the heater 5 by the heat exchanger 9.

With such a configuration, as in the second embodiment, the temperature of the regeneration air entering the heater 5 can be increased in advance, so that the power consumption of the heater can be reduced. Further, before the moisture absorbing body 22 enters the moisture absorbing section 2a with the rotation of the rotating body 21, the temperature is lowered by the moisture absorbing air passing through the branch path 7a, so that the moisture absorbing efficiency in the moisture absorbing section 2a can be improved.

At this time, the moisture-absorbing air passing through the branch path 7a, which has become high in temperature, is recovered in heat by the heat exchanger 9, so that it becomes low in temperature and is discharged out of the dehumidifier 1, so that the room temperature is not raised. . Here, a part of the moisture in the hygroscopic body 22 is released to the outside of the dehumidifier 1 by the moisture-absorbing air passing through the branch path 7a, but the indoor humidity is increased by configuring the flow rate in the branch path 7a to be small. It is possible to lower the temperature of the moisture absorber without causing the moisture absorption.

Next, a dehumidifier according to a fourth embodiment will be described with reference to FIG. According to the figure, the third embodiment (see FIG. 3)
2 has the same configuration as that of FIG.
5) can be selected from forward rotation (arrow A) and reverse rotation (arrow A '). By doing so, the same effect as in the third embodiment can be obtained by rotating the rotating body 21 forward in the direction of arrow A.

When the rotating body 21 is reversed in the direction of the arrow A ', the temperature of the collecting section 2bb through which the branch path 7a passes is low, so that the branch path 7a and the moisture absorption path 7 are the same as in the conventional example (see FIG. 24). It can be regarded as the moisture absorption path 7. At this time, the rotation direction of the rotating body 21 with respect to the reproducing unit 2b (arrow A ')
The relatively high-temperature dry air for moisture absorption passing through the front high-temperature portion 2bc is discharged to the outside of the dehumidifier 1 as in the conventional example. Since the clothes can be dried using the high-temperature dry air, the user can selectively use applications such as priority on dehumidification or clothes drying by selecting the rotation direction of the rotating body 21.

Next, a dehumidifier according to a fifth embodiment will be described with reference to FIG. According to the figure, the third embodiment (see FIG. 3)
The blower 12 is provided in the branch path 7a. With such a configuration, the moisture absorbing air passing through the branch path 7a is absorbed by the hygroscopic body passing through the branch path 7a so that the amount of water released outside the dehumidifier 1 does not increase and the dehumidifying performance is reduced. The flow rate of the working air can be set optimally.

Next, a dehumidifier according to a sixth embodiment will be described with reference to FIG. According to the figure, a condensation prevention heater 17 is provided on the regeneration path 8 after passing through the condenser 3.
Thus, the condensation of the regeneration path 8c through which the regeneration air cooled to the dew point passes can be prevented.

Next, a dehumidifier according to a seventh embodiment will be described with reference to FIG. According to the figure, a branch path 7b is provided which branches from the moisture absorption path 7 so as not to pass through the moisture absorber 2. By doing so, the flow rate of the moisture-absorbing air passing through the condenser 3 can be increased, and the efficiency of condensation can be improved. When a predetermined amount or more of moisture-absorbing air is passed through the moisture absorber 2, the moisture-absorbing ability of the moisture-absorbing body 22 (see FIG. 25) is reduced. Therefore, the moisture-absorbing air of a predetermined amount or more is dehumidified without passing through the moisture-absorber 2 by the branch path 7b. It is released outside the machine 1.

In order to allow a predetermined amount of air for moisture absorption to pass through the moisture absorber 2, a limiting plate is provided in the moisture absorption path 7 so as to shield the moisture absorption air entering the moisture absorber 2 as shown in the detailed view of the main part of FIG. 3
2, and the limiting plate 32 is formed with a through hole 32a. By doing so, the amount of air passing through the limiting plate 32 becomes constant, and the flow of air entering the moisture absorber 2 becomes uniform, thereby improving moisture absorption efficiency. Similarly, a restriction plate 43 having a through-hole 43a may be provided between the heater 5 and the moisture absorber 2 in the regeneration path 8 so that the flow of the regeneration air entering the regeneration section 2b is made uniform. Thus, the temperature of the moisture absorbent 22 can be increased uniformly.

Next, an eighth embodiment will be described with reference to FIGS. 9A, 9B, and 9C show a top view, a front view, and a side view of the condenser 3 of the present embodiment.
FIG. 10 is a schematic perspective view showing a portion D in FIG.
According to these figures, the high-temperature and high-humidity regeneration air flowing into the condenser 3 from the air inlet 37 provided above the condenser 3 has a plurality of condensing passages 34 ( (First passage) and proceeds downward.

The through hole 3 is provided between the adjacent condensation passages 34.
6 is provided, and the low-temperature moisture-absorbing air is applied to the surface 3 as indicated by the arrow F.
d passes perpendicularly to d and exchanges heat with the regeneration air to condense the moisture in the regeneration air. The dried regeneration air is sent out from an air outlet 38 provided at the lower part of the condenser 3, and the condensed water flows down through a condensation passage 34 and is discharged from an outlet 39.

The air outlet 38 is provided at a position not in contact with the lower end surface 40b so that condensed water flowing down the lower end surface 40b does not leak from the air outlet 38. In addition, a guide surface 40a is provided to guide the regeneration air that has passed through each condensing passage 34 and merges to the air outlet 38.
The guide surface 40a prevents the regeneration air from leaking from the outlet 39, and the condensed water drops from the hole (not shown) provided in the guide surface 40a to the lower end surface 40b while flowing down the inclined guide surface 40a. It has become. The passage 35 (second passage) formed so as to be connected across the condensing passage 34 is provided to make the pressure in each condensing passage 34 uniform.

Such a condenser 3 is made of a resin. As shown schematically in FIG. 11, a resin 42 such as polypropylene is formed by a mold 41 while blowing air into the inside as shown by an arrow G. After performing blow molding or the like, the through-hole 36 can be easily formed by punching out by Thomson processing or the like. Therefore, the weight of the dehumidifier is reduced compared to the conventional metal condenser, the dehumidifier body is easily carried, and the material cost and the processing cost can be reduced. Further, since no rust is generated, it is possible to eliminate a cause of failure such as leakage of water from a hole due to rust and to improve reliability.

Although the heat conductivity is lower than that of a metal condenser, the condensation efficiency is reduced.
The thickness is reduced to 0.7 mm, and the cross-sectional shape of the condensing passage 34 is made to be a short slot in the width direction (see the portion H in FIG. 9).
The condensation efficiency is improved by increasing the number of passages 34 for condensation. Condensing passage 34 in the present embodiment
Has an inner diameter D = 8.6 mm in the width direction and W = 20.6 in the thickness direction.
mm, and the pitch in the width direction of the condensing passage 34 is P = 15.
mm.

Further, a plurality of condensers 3 may be arranged in parallel with the surface 3d and arranged so as to be shifted so that the through holes 36 are not arranged in a straight line. In this way, after the low-temperature air from the direction of arrow F passes through the through hole 36 of the first condenser 3,
Part of the air is supplied to the surface 3d of the second condenser 3 (condensing passage 3).
4), vortex is generated, and after stopping for a very short time, 2
Since it passes through the through hole 36 of the second condenser 3, the substantial contact area with the high-temperature air is increased, and the condensation efficiency is improved.

Next, a ninth embodiment will be described with reference to FIG. According to the figure, a primary water storage tank 10 for storing condensed water is provided.
And is connected to the outlet 39 of the condenser 3 of the eighth embodiment. A water level sensor 14 is installed in the primary water storage tank 10, and when a predetermined water level J is reached, water is sent out to a secondary water storage tank (not shown) by the pump 11, and when the water level falls (water level W), the pump 11 is stopped. It has become.

According to such a configuration, the outlet 39 of the condenser 3 is always filled with condensed water and is blocked, and the water surface further prevents the regeneration air from leaking from the outlet 39. Will be able to do it. Further, when the water level J is disposed below the lower end 38a of the air outlet 38, when the water level sensor 14 or the pump 11 fails, the water level rises and closes the air outlet 38 so that the outflow of the regeneration air flows out. The amount decreases.

As shown in the side view of FIG. 13, in the case of a closed circuit in which the regeneration air passing through the condenser 3 is introduced into the heater 5, when the flow rate of the regeneration air entering the heater 5 decreases, the heater 5 Since the temperature of the regeneration air exiting the heater 5 is higher than a predetermined temperature, the dehumidifier 1 detects that the temperature of the regeneration air exiting the heater 5 is high by the temperature sensor 13 or the like.
Can be stopped. This makes it possible to detect a failure of the water level sensor 14 and the pump 11 to prevent water leakage.

In the eighth and ninth embodiments, the condenser 3 has been described. However, since the heat exchange between high-temperature air and low-temperature air is performed, the condenser 3 is used in the first to fifth embodiments. The same configuration can be applied to the heat exchanger 9 as described above, and the same effect can be obtained.

Next, a tenth embodiment will be described with reference to FIG. FIG. 14 is a schematic diagram illustrating the configuration of the heater 5 of the present embodiment. According to FIG.
j and 8k denote first and second heating passages 5 passing through the heater 5.
c and 5d, and pass through the regeneration units 2b1 and 2b2 of the moisture absorber 2. The moisture absorber 22 of the regeneration unit 2b1 of the moisture absorber 2 (FIG. 25)
(See FIG. 25) is preheated through the regenerating section 2b2 behind the rotating body 21 (see FIG. 25) rotating in the moisture absorber 2 and thus has residual heat and releases moisture. Therefore, even if the temperature of the regeneration air passing through the regeneration path 8j is lower than that of the regeneration air passing through the regeneration path 8k, the moisture absorbed can be absorbed and the moisture absorbent 22 can be regenerated.

Therefore, by making the temperature of the regeneration air heated through the first temperature increasing passage 5c lower than the temperature of the regeneration air heated through the second temperature increasing passage 5d, moisture absorption is achieved. The temperature of the regenerating section 2b1 of the vessel 2 is not set to an unnecessarily high temperature.
Absorbing body 2 that moves to moisture absorbing section 2a with rotation of direction A in FIG.
2 can be kept low, so that the amount of heat released to the outside of the dehumidifier 1 by the moisture-absorbing air passing through the moisture-absorbing path 7 can be suppressed, and the power consumption can be reduced without using wasteful power. it can.

Further, the temperature of the regeneration air passing through the first temperature raising passage 5c may be prevented from rising. In this case, similarly, the moisture absorber 22 heated by the regeneration air passing through the regeneration path 8k may be used. Is absorbed by the regeneration air passing through the regeneration path 8j, and the temperature of the moisture absorber 22 is reduced before the moisture absorber 22 of the regeneration unit 2b1 enters the moisture absorber 2a with the rotation of the rotating body 21. The ability to absorb moisture can be improved.

Next, an eleventh embodiment will be described with reference to FIG. FIG. 15 is a schematic diagram illustrating the configuration of the heater 5 of the present embodiment. According to FIG.
The j and 8k pass through the inner peripheral portion 5e and the outer peripheral portion 5f of the heater 5, and pass through the regenerating portions 2b3 and 2b4 of the moisture absorber 2. The outer playback section 2b4 is the inner playback section 2b3.
Since the amount of the regeneration air is larger, the density of the electric heating element 5a (see FIG. 26) constituting the heater 5 is made smaller by making the inner peripheral portion 5e smaller than the outer peripheral portion 5f so that the temperature of the regeneration air passing through the regeneration path 8j is increased. Is lower than the temperature of the regeneration air passing through the regeneration path 8k, the temperature of the inner peripheral regeneration unit 2b3 does not become unnecessarily high, and the temperature of the moisture absorber 22 (see FIG. 25) rotating and passing through the regeneration unit 2b becomes uniform. Thus, power consumption can be reduced without using wasteful power.

Next, a twelfth embodiment will be described with reference to FIG. FIG. 16 is a front view showing the heater 5 of the present embodiment. The heater 5 is composed of an electric heating element 5a arranged so as to cover the regeneration section 2b of the moisture absorber 2, and the electric heating element 5a is connected to the regeneration section 2b.
Is formed so that at least 1/2 does not cross the center line J that bisects. In this way, when the rotating body 21 (see FIG. 25) rotates inside the moisture absorber 2 behind the heater 5, any point in the rotating body 21 contacts the electric heating element 5 a in the same manner. Are alternately heated to the regenerating air behind the electric heating element 5a and the regenerating air behind the gap 5b, so that the moisture absorbent 22 of the regenerating section 2b is uniformly heated, and wasteful electric power can be used. Power consumption can be reduced.

Here, when the length of the electric heating element 5a which is not orthogonal to the center line J becomes 以下 or less with respect to the entire length of the electric heating element 5a, the rotation of the rotating body 21 causes the electric heating element 5a or the gap 5b to be closed. The number of points that rotate and move only behind is increased, and uniform temperature rise of the reproducing unit 2b is not performed.

Further, as shown in the thirteenth embodiment of FIG. 17, the electric heating elements 5a are arranged so as to be arranged in a plurality of rows in the inflow direction of the regeneration air, and the inclination angle of the electric heating elements 5a with respect to the center line J in each row. It is desirable that the temperature is different because the temperature of the regenerating section 2b can be further uniformly increased.

Next, a fourteenth embodiment will be described with reference to FIG. In the present embodiment, the heater 5 (see FIG. 26)
Is not required, and the moisture absorbent is regenerated in the moisture absorber 2. According to FIG. 18A, a heat-absorbing material 52 such as glass fiber is melted while a moisture absorbent 53 such as zeolite is melted.
Is dipped, pulled up and cooled, a fibrous fibrous absorbent 54 can be formed.

The fibrous moisture absorber 54 is wound around the heating wire 51 and the rotating body 21 rotates inside the moisture absorber 2 (see FIG. 25).
By filling the inside and passing a current through the heating wire 51, the moisture absorbing body 53 can be heated to release moisture. In this case, the heater 5 is not required, so that the size of the dehumidifier 1 can be reduced. Further, as shown in (b), the fibrous moisture absorber 54 may be knitted in a net shape so as to cover around the heating wire 51.

As shown in FIGS. 19A and 19B, the rotating body 21 is divided into a plurality of blocks 21a to 21f, and a fibrous material filled in each block is shown. The heating wire 51 covered with the moisture absorbing body 54 (see FIG. 18) has a terminal 51a having a tip fixed to one end of the rotating body 21.
When each block rotates and passes through the reproducing section 2b (see FIG. 1), the terminal 51a is in contact with the electrode 31 provided on the bearing 27, thereby forming the moisture absorbent 53 (FIG. 18). (See FIG. 2) passes through the regeneration section 2b only when the temperature of the moisture absorbent 53 is increased.

Further, as shown in a fifteenth embodiment of FIG. 20, the integral member 55 in which the heating wire 51 is covered with the fibrous moisture absorber 54 is integrated with the flexible member 56 in a belt shape to form the moisture absorber 5.
3 can be set to a desired density and installed in the moisture absorber 2.

Next, a sixteenth embodiment will be described with reference to FIG. FIG. 21 is a front view showing the support frame 24 of the rotating body 21 (see FIG. 25) in the present embodiment. According to the figure, the grid holes 24c are formed with concentric ribs 24a and radial ribs 24b so that air for regeneration or air for moisture absorption can pass through.
And is formed by. Here, the radial ribs 24b connecting the three adjacent concentric ribs 24a are not formed on a straight line but are shifted.

The outer diameter of the support frame 24 is increased by the length of the outermost radial ribs 24b and the outermost concentric ribs 24a thermally expanded, and the thermal expansion is reduced as compared with the case where the radial ribs are provided in a straight line. be able to.
As a result, even if the moisture absorption body 22 repeatedly rises and falls in temperature, the support frame 24 repeatedly expands and contracts and deforms. The reliability can be improved.
