Description

The present invention relates to a dehumidifying device included in a drying device.

The air processing device described in Patent Document 1 below includes a cabinet and a suction hood provided on the back side of the cabinet. The suction hood is provided with a suction port. The cabinet is provided with an air passage communicating with the suction port, an air blower, a filter, and a dust collecting means arranged in the air passage, and an air outlet communicating with the air passage. When the blower operates, air around the air treatment device is sucked into the air path from the suction port and passes through the filter and dust collection means.

Filters remove oil smoke, water vapor, and odors from the air that passes through them. The dust collecting means includes a discharge electrode and a counter electrode that are arranged opposite to each other with a gap in between. Small oil smoke and water vapor that cannot be removed by the filter are charged and collected by the discharge generated between the discharge electrode and the counter electrode. The air that has flowed into the air passage is thus purified by passing through the filter and the dust collecting means, and then is blown out of the air processing device from the air outlet.

As a structure of an electrode used in so-called electrostatic precipitator, an electrode structure of a NAFCO electrostatic precipitator using a needle discharge electrode and a parallel plate electrode is known (see Non-Patent Document 1). For example, when considering the configuration of an electrode in a dehumidifying device that charges and collects moisture by the discharge of a discharge electrode in the air path of a drying device in which an air path is formed, in the electrode structure described above, the discharge electrode is needle-shaped. Therefore, it is difficult to uniformly generate an electric field within the air path.

As a means to solve this problem, a plurality of linear discharge electrodes are placed between the plate-shaped dust collection electrodes, and in order to keep the spacing between each linear discharge electrode constant, the lower end of each linear discharge electrode is swayed. It is possible to use a Cottrell type electrode in which a stopping weight is arranged (see Non-Patent Document 1).

Patent No. 4657168

https://www.nafco.info/page3 Nafco Corporation homepage

The Cottrell type electrode shown in Non-Patent Document 1 has a structure in which a weight is placed at the lower end of each linear discharge electrode to prevent sway, so the discharge electrodes can be arranged uniformly within the air path. There is a problem in that when high-velocity wind flows inside, each linear discharge electrode sways, making it impossible to maintain a constant gap and tension between each linear discharge electrode.

The present invention was made against this background, and it is possible to uniformly generate an electric field in the air passage, and to maintain the spacing and tension between each electrode even when high-velocity wind flows in the air passage. The purpose of the present invention is to provide a dehumidifying device that can maintain the following conditions.

The present invention is a dehumidifying device for dehumidifying air passing through a circulation path, and includes a case having an inlet and an outlet, and a ventilation path extending linearly from the inlet to the outlet as a uniform open space. , a dehumidification unit having a plurality of high-voltage electrode members and a plurality of low-voltage electrode members disposed in the ventilation path, each of the high-voltage electrode members comprising a frame made of an insulating material that partitions a window; A single wire line is stretched and held by the frame so as to cross the window multiple times at regular intervals, and a plurality of vertical lines of the discharge wire are provided. The frame is arranged in the ventilation passage so that the parts are lined up in order from the inlet to the exit in the ventilation passage, each of the low voltage electrode members is formed of a conductive thin plate, and the high voltage electrode member The discharge wire is disposed in the ventilation passage so as to face the discharge wire at a predetermined distance.

Further, in the present invention, the conductive thin plate and the discharge wire face each other at a predetermined interval S when viewed in a direction perpendicular to the air passage direction in the ventilation path, and the The plurality of vertical line portions of the discharge wire stretched across the discharge wire are arranged at regular intervals of 0.5S to 5S in the ventilation passage when viewed in the air passage direction.

Further, in the present invention, the frame is provided with a tension adjustment member that adjusts the tension of the discharge wire stretched on the frame.

Further, in the present invention, the tension adjustment member includes a tension adjustment spring that applies tension to the discharge wire with elastic force.

According to the present invention, the discharge wire, which is a high-voltage electrode member, and the conductive thin plate, which is a low-voltage electrode member, arranged in the ventilation path are provided in parallel to the air passage direction. Further, even if air passes through the ventilation path, the discharge wire does not sway, and the distance between it and the conductive thin plate does not change. Then, by applying a high voltage to the discharge wire, which is a high voltage electrode member, the discharge wire discharges and generates an electric field. Moisture (mist) contained in the air passing through the ventilation path is charged by the electric field and collected on the surface of the conductive thin plate, which is a low voltage electrode member. Therefore, the air passing through the ventilation path can be efficiently dehumidified.

Further, according to the present invention, in the ventilation passage, the discharge wire and the conductive thin plate face each other with a predetermined interval S in the direction perpendicular to the direction in which the air flows, and the discharge wire They are arranged at regular intervals of 0.5S to 5S along the flow direction. Therefore, an appropriate electric field is generated in the ventilation path by the discharge of the discharge wire, and the moisture (mist) contained in the air is charged and smoothly collected on the conductive thin plate.

According to the present invention, since the discharge wire is maintained at an appropriate tension by the tension adjustment member, a constant discharge capacity can always be ensured.

FIG. 4 is a perspective view of the dehumidifying device 30 taken from the upper right side of the front side, and the inside of the ventilation passage 31 is shown in a transparent state. FIG. 5 is an exploded perspective view of the dehumidifier 30. 6 is a front view of the dehumidifier 30, FIG. 7 is a plan view of the dehumidifier 30, and FIG. 8 is a rear view of the dehumidifier 30. Furthermore, FIG. 9 is a perspective view of the dehumidifying device 30 drawn from the upper left on the back side.

The dehumidifier 30 according to this embodiment will be described in detail with reference to FIGS. 4 to 9.

The dehumidifier 30 includes a case 32 provided with a ventilation passage 31 and a dehumidification unit 33 disposed within the ventilation passage 31. The case 32 is made of an insulating material, such as insulating plastic. The ventilation path 31 formed in the case 32 constitutes a part of the circulation path 12. The ventilation passage 31 has an inlet 34 that opens on the back side (Y2 direction) of the case 32 and an outlet 35 that opens on the front side (Y1 direction) of the case 32, and extends linearly from the inlet 34 to the outlet 35 in the Y direction. It defines an extending, approximately square opening space.

The dehumidification unit 33 disposed within the ventilation path 31 includes a plurality, for example, three, high voltage electrode members 36 and a plurality, for example, four, low voltage electrode members 37. The three high-voltage electrode members 36 function as a charging section that charges mist, water droplets, or water vapor contained in the humid air flowing through the ventilation path 31 that forms part of the circulation path 12 by electrical discharge. The four low voltage electrode members 37 function as a collector section that collects charged mist, water droplets, or water vapor.

FIG. 10 is a perspective view showing an example of the configuration of the high voltage electrode member 36. In the high voltage electrode member 36 shown in FIG. 10, the left side is the front (Y1 direction) when attached to the dehumidifier 30, and the right side is the rear (Y2 direction). The high voltage electrode member 36 has a substantially rectangular frame 38 made of an insulating material, and a substantially rectangular opening 39 surrounded by the frame 38 is defined. In the window 39, a plurality of discharge wires 40 vertically extending inside the window 39 are arranged at equal intervals from the front side (Y1 direction) to the rear side (Y2 direction) inside the window 39. The plurality of discharge wires 40 (six in the example of FIG. 10) running longitudinally within the window 39 are composed of one wire line in which six wires are connected in series. That is, one tungsten wire wire 40, for example, is stretched with a constant tension so as to run longitudinally within the window 39 from the front side of the upper frame 38U of the frame 38 to the front side of the lower frame 38D. It is sent to the side at a certain distance, is stretched with a certain tension so as to cross the inside of the window 39 from the lower frame 38D to the upper frame 38U, and is sent to the rear side at a certain distance along the upper frame 38U, and the upper frame 38U The discharge wires 40 are stretched with a constant tension so as to extend vertically through the window 39 toward the lower frame 38D, and by repeating this, six discharge wires 40 are stretched vertically through the window 39.

The front end of one tungsten wire 40 is connected to an electrode plate 41 provided above the front frame 38F of the frame 38.

Further, the rear end portion of one tungsten wire wire 40 is fixed to the rear frame 38B of the frame 38 via a tension adjustment member 42 provided on the rear frame 38B. The tension adjustment member 42 can be made of, for example, a spring member.

In this embodiment, a single tungsten wire is used as the discharge wire 40 that vertically traverses inside the window 39, and extends in parallel from the front Y1 to the rear Y2 in the vertical direction Z within the frame 38. Although six discharging wires 40 are illustrated as an example, the number of discharging wires 40 is not limited to six, but may be a plurality of discharging wires.

FIG. 11 is an example of the frame 38 that constitutes the high voltage electrode member 36. As shown in FIG. 11, the frame 38 may be a main frame 38M and a subframe 38S that are fitted together so as to be pasted together. If the frame 38 is made of a bonded and fitted structure of the main frame 38M and the sub-frame 38S, when the plurality of discharge wires 40 extending longitudinally through the window 39 of the frame 38 are stretched on the frame 38, the main frame 38M and the sub-frame 38S are bonded together. There is an advantage that both ends of the discharge wire 40 can be held between the sub-frame 38S and the discharge wire 40 can be easily stretched with a predetermined tension.

Furthermore, a projection 381 for tension adjustment may be provided on the outer edge of the main frame 38M, and similarly, a projection 382 for tension adjustment may be provided on the outer edge of the subframe 38S. By providing the protrusions 381 and 382, when the discharging wire 40 is sandwiched between the main frame 38M and the sub-frame 38S, unevenness is created in the pinched area, and tension is applied to the discharging wire 40 by the protrusions 381 and 382. It has the advantage that it can be tensioned and the applied tension is difficult to loosen.

Referring again to FIGS. 4 to 9, in the ventilation passage 31 of the case 32, when viewed from the front, the high voltage electrode members 36 are each vertically erected, and three high voltage electrodes are arranged at equal intervals in the left and right direction. Members 36 are arranged in parallel. Therefore, the plurality of discharge wires 40 of each high voltage electrode member 36 are arranged in the left-right direction X at equal intervals from the entrance 34 to the exit 35 of the ventilation passage 31. Therefore, the air flowing through the ventilation path 31 from the inlet 34 to the outlet 35 flows from the rear side to the front side on both sides of the window 39 along the window 39 of each high voltage electrode member 36, and flows through the plurality of discharge wires. 40 in order.

A wire support stay 43 is provided in order to maintain the arrangement of the three high voltage electrode members 36 arranged in parallel in the left-right direction X in the ventilation path 31 as described above. The wire support stay 43 is made of a conductive material, such as a metal such as copper, nickel, aluminum, or stainless steel, and is provided so as to cross the front side of the case 32 in the lateral direction (X direction). The wire support stay 43 is spaced a certain distance from the front of the case 32 toward the front Y1. A right end 431 and a left end 432 of the wire support stay 43 are bent at right angles toward the rear Y2 in plan view and are fixed to a fixing protrusion 44 protruding from the side surface of the case 32.

The wire support stay 43 is electrically connected to each electrode plate 41 of the three high voltage electrode members 36 arranged in the ventilation path 31 and holds the three high voltage electrode members 36.

In the ventilation passage 31 of the case 32, the four low voltage electrode members 37 are arranged to face the three high voltage electrode members 36 on both sides. The low voltage electrode member 37 has a thin plate shape made of a conductive plate such as a stainless steel plate or an aluminum plate. The low voltage electrode members 37 are disposed at the left and right ends of the ventilation passage 31 when viewed from the front, and are also disposed between the high voltage electrode members 36 and 36 .

Since the low voltage electrode member 37 has a thin plate shape, a holding protrusion 45 for receiving and holding the lower side thereof may be provided, for example, on the bottom surface of the ventilation passage 31, for example.

A collector support stay 46 made of a metal plate is provided on the back side of the case 32 and is electrically connected to the four low voltage electrode members 37 and holds the four low voltage electrode members 37. A left end portion 462 of the collector support stay 46 is bent downward along the left side surface of the case 32 so that it can function as a grounding electrode.

In the left-right direction X when viewed from the front, which is a direction perpendicular to the passing direction (Y direction) of air flowing through the ventilation passage 31, the opposing interval between the high voltage electrode member 36 and the low voltage electrode member 37 within the ventilation passage 31 is as follows: For example, the distance is S (see FIG. 6). The spacing S may be about 10 mm, for example.

On the other hand, the distance V between the discharge wires 40 and the discharge wires 40 described with reference to FIG. 10 may be set to V=0.5S to 5S, for example. That is, the interval V may be about 5 to 50 mm, for example.

The operation of the dehumidifier 30 in this embodiment is as follows.

A high voltage, for example, several kV to several tens of kV, is applied to the left end portion 432 of the wire support stay 43 from the high voltage circuit board 50. At this time, the left end portion 462 of the collector support stay 46 electrically connected to the four low voltage electrode members 37 is connected to the ground potential. When a high voltage is applied via the wire support stay 43, each discharge wire 40 of the high voltage electrode member 36 discharges. Then, the air around the discharge wire 40 becomes a plasma state, and the molecules of this air are positively ionized and move to the low voltage electrode member 37. As a result, a current of several tens of microamperes flows between the high voltage electrode member 36 and the low voltage electrode member 37.

In the ventilation passage 31 of the case 32, moisture (that is, mist, water droplets, or water vapor) contained in the air flowing between the high voltage electrode member 36 and the low voltage electrode member 37 is cationic ions generated by the discharge of the discharge wire 40. It becomes positively charged by colliding with electrons and electrons. Moisture (that is, mist, water droplets, or water vapor) charged to the positive electrode is attracted to and collected by the low voltage electrode member 37 at the ground potential. Thereby, the air passing through the ventilation path 31 is dehumidified.

As described above, the dehumidifier 30 according to the present embodiment charges moisture (that is, mist, water droplets, or water vapor) contained in the humid air flowing through the ventilation path 31 of the case 32 by electrical discharge from the discharge wire 40. A high voltage electrode member 36 is provided as a part. The dehumidifier 30 also includes a low voltage electrode member 37 as a collector section that collects charged moisture (that is, mist, water droplets, or water vapor).

Referring to FIG. 3, the high voltage circuit board 50 that applies a high voltage to the left end portion 432 of the wire support stay 43 of the dehumidifier 30 is provided on the back left side of the dehumidifier 30 in the left direction X1. desirable. This is because, in this embodiment, the left side of the case 32 of the dehumidifier 30 protrudes so that the left end 432 of the wire support stay 43 moves away from the ventilation path 31. Therefore, by providing the high voltage circuit board 50 on the left side, leakage of current in the high voltage circuit board 50 is prevented, and discharge defects and the like are less likely to occur.

The moisture collected on the low-voltage electrode member 37 becomes relatively large droplets on the surface of the thin plate-shaped low-voltage electrode member 37, and is transmitted through the surface of the low-voltage electrode member 37 due to its own weight to the bottom of the ventilation passage 31. run down.

The bottom surface of the ventilation passage 31 may have a downward slope. Then, the moisture collected by the low voltage electrode member 37 tends to flow through the bottom surface of the ventilation passage 31 toward the front Y1 side.

Since the case 32 is housed within the duct partition member 10B, moisture accumulated on the bottom surface of the ventilation passage 31 of the case 32 is drained through a dedicated drainage channel 17 that communicates with the duct partition member 10B. .

Referring to FIG. 3, in this embodiment, the heater 16 is arranged downstream of the dehumidifier 30 and adjacent to the dehumidifier 30 when viewed in the flow direction of the air flowing through the circulation path 12. . Further, in the dehumidifier 30 , a wire support stay 43 that supports the high voltage electrode member 36 is provided on the downstream side of the ventilation path 31 of the dehumidifier 30 . Therefore, the wire support stay 43 is always heated by the heater 16, and dew condensation is prevented.

In this embodiment, when viewed from the front, the case 32 of the dehumidifier 30 has a ventilation passage 31 partitioned on the right side, and a trapezoidal shape with a flat upper surface and an upwardly inclined lower surface on the left side of the ventilation passage 31. A configuration with an elongated case profile has been described. The reason why the case 32 is shaped as described above is to facilitate mounting the dehumidifier 30 on the circulation path 12 and to separate the ventilation path 31 and the high voltage electrode member 36. Therefore, the shape of the case 32 of the dehumidifier 30 is not limited to the above embodiment.

Furthermore, in the present embodiment, the dehumidification unit 33 disposed in the ventilation path 31 has been described as having a configuration including three high voltage electrode members 36 and four low voltage electrode members 37, but the cross-sectional area of the ventilation path etc. Depending on the situation, a plurality of high voltage electrode members may be arranged, and a plurality of low voltage electrode members may also be arranged. In that case, the high voltage electrode members and the low voltage electrode members may be arranged so as to alternately face each other when viewed in the X direction perpendicular to the air flow direction (Y direction) in the ventilation passage.

Further, in the present embodiment, a drying device incorporated in a washer/dryer has been described as an example, but the drying device and dehumidifying device according to the present invention can be used in a washing machine with a drying function, a clothes dryer, a dishwasher, etc. It can also be applied as a device or a dehumidifying device.

The present invention is not limited to the configuration of the embodiments described above, and various changes can be made within the scope of the claims.
