[0009] An embodiment of the present disclosure will be described below. Note that the following description is an example of an electronic dehumidifier according to the present disclosure, and the technical scope of the present disclosure is not limited to the illustrated example.

[0010] [Configuration of electronic dehumidifier 1] First, a configuration example of an electronic dehumidifier 1 according to this embodiment will be described. Fig. 1 is a cross-sectional view illustrating a state in which the electronic dehumidifier 1 according to this embodiment is installed in an equipment box 51. Fig. 2 is an enlarged cross-sectional view showing the electronic dehumidifier 1 shown in Fig. 1.

[0011] 1, electronic dehumidifier 1 is used to dehumidify the inside of equipment box 51 of electrical equipment 5, for example. This electronic dehumidifier 1 atomizes dehumidified water W removed from humid air A1 inside equipment box 51 and discharges mist (atomized dehumidified water) F to the outside of equipment box 51.

[0012] In the illustrated example, the electrical equipment 5 is provided with a door 52 on the front side (left side of the paper in FIG. 1) that can open the equipment box 51. The electronic dehumidifier 1 may be installed, for example, in a corner on the rear side (right side of the paper in FIG. 1) inside the equipment box 51.

[0013] As shown in Figure 2, the electronic dehumidifier 1 comprises a case 2 installed inside the equipment box 51, a dehumidifying section 3 that dehumidifies the humid air A1 inside the equipment box 51, and an exhaust section 4 that exhausts mist F formed by atomizing the dehumidified water W removed from the humid air A1 by the dehumidifying section 3 to the outside of the equipment box 51.

[0014] Electronic dehumidifier 1 has a configuration in which dehumidifying section 3 and exhaust section 4 are housed in case 2. In other words, electronic dehumidifier 1 is a single unit in which both dehumidifying section 3 and exhaust section 4 are housed in case 2. This makes it easy to install electronic dehumidifier 1 in equipment box 51.

[0015] (Case 2) Case 2 is, for example, a vertically long housing installed inside equipment box 51. Case 2 has an air intake port 21 on the front side for drawing in humid air A1. Case 2 also has an exhaust port 22 on the top side for discharging dehumidified dry air A2. Case 2 also has a mist outlet 23 on the back side for discharging mist F.

[0016] The mist outlet 23 is a through-hole for discharging the mist F generated in the tank 43 of the discharge unit 4, which will be described later, to the outside of the equipment box 51. The mist outlet 23 is formed by penetrating each of the tank 43, the case 2, and the equipment box 51.

[0017] Humid air A1 containing moisture tends to accumulate in the lower part of the interior of equipment box 51. For this reason, it is preferable that air intake 21 be located near the floor surface inside equipment box 51. This makes it possible to efficiently suck humid air A1 into the interior of case 2 through air intake 21, thereby enhancing the dehumidifying effect.

[0018] (Dehumidification section 3) The dehumidifying unit 3 is a structural unit that has the function of dehumidifying the humid air A1 sucked in through the intake port 21. The dehumidifying unit 3 is provided relatively above the intake port 21.

[0019] The dehumidifying unit 3 includes a Peltier element (cooling unit) 31, a cooling fin 32 connected to a cooling surface 31A of the Peltier element 31, and a heat dissipating fin 34 located above the cooling fin 32 and connected to a heat generating surface 31B of the Peltier element 31 via a heat conductor 33. The dehumidifying unit 3 also includes a power supply unit 35 located above the heat dissipating fin 34 and equipped with a control circuit 10 (see FIG. 3 ), and a fan 36 located above the power supply unit 35 for drawing in humid air A1 through the intake port 21 and discharging dehumidified dry air A2 through the exhaust port 22.

[0020] In this dehumidifying section 3, humid air A1 is drawn into the inside of the case 2 from the air intake 21 by the rotation of the fan 36, and is dehumidified and cooled by the cooling fins 32 cooled by the Peltier element 31. The air dehumidified by the cooling fins 32 is then heated by the heat dissipation fins 34 and becomes dry air A2, which is then exhausted from the exhaust port 22. The dry air A2 exhausted from the exhaust port 22 is only dehumidified, and the temperature of the dry air A2 is adjusted so that it changes little to the temperature of the humid air A1 drawn into the case 2.

[0021] (Discharge section 4) The discharge unit 4 is a structural unit that has the function of atomizing the dehumidified water W removed from the humid air A1 by the dehumidifying unit 3 and discharging it to the outside of the equipment box 51. The discharge unit 4 is provided relatively lower than the dehumidifying unit 3.

[0022] Discharge unit 4 is provided below cooling fins 32 and includes a water receiver 41 that receives dehumidified water W, a water conduit 42 that is connected to water receiver 41 and guides the dehumidified water W to tank 43, and tank 43 that stores the dehumidified water W received by water receiver 41. Discharge unit 4 also includes a water depth sensor 44 that detects the depth of the dehumidified water W stored in tank 43, and a piezoelectric vibrator (atomization unit) 45 that atomizes the dehumidified water W in tank 43 by ultrasonic vibration U.

[0023] The tank 43 has an insertion opening 43A on the top side, into which the water guide pipe 42 is inserted. The water guide pipe 42 is inserted and fitted into this insertion opening 43A. A sealing member may be provided to fill the gap between the inner circumferential surface of the insertion opening 43A and the outer circumferential surface of the water guide pipe 42 so that the mist F does not leak out from the gap.

[0024] The water depth sensor 44 is a sensor that detects the depth of the dehumidified water W accumulated in the tank 43. The water depth sensor 44 outputs a detection signal (water depth data) corresponding to the depth of the dehumidified water W to the control circuit 10. The control circuit 10 controls the piezoelectric vibrator 45 according to the water depth based on the detection signal acquired from the water depth sensor 44. The measurement method of the water depth sensor 44 may be ultrasonic, radio wave, pressure, differential pressure, capacitance, float, or other methods.

[0025] Piezoelectric vibrator 45 is an ultrasonic vibrator that atomizes dehumidified water W with ultrasonic vibrations U. Piezoelectric vibrator 45 generates ultrasonic vibrations U when a high-frequency voltage is applied, and these ultrasonic vibrations U vibrate the surface of dehumidified water W. This generates mist F, which is made up of fine water particles, from the surface of dehumidified water W. Piezoelectric vibrator 45 has an oscillation frequency and oscillation amplitude controlled according to the depth of dehumidified water W, and generates ultrasonic vibrations U according to the water depth. Note that the atomization unit of the present disclosure may be any unit that atomizes dehumidified water W using ultrasonic waves. Therefore, other ultrasonic vibrators may be used as the atomization unit of the present disclosure instead of piezoelectric vibrator 45.

[0026] In this discharge section 4, the dehumidified water W removed from the humid air A1 by the dehumidifying section 3 is led from the water receiver 41 through the water conduit 42 to the tank 43. The dehumidified water W accumulated in the tank 43 is atomized into mist F by the ultrasonic vibrations U generated by the piezoelectric vibrator 45, and is discharged from the mist discharge port 23 into the air outside the equipment box 51.

[0027] It should be noted that a mist discharge pipe 46 that connects the inside of the tank 43 with the outside of the equipment box 51 may be attached to the mist discharge port 23. The mist discharge pipe 46 is, for example, an L-shaped curved pipe, and in the example shown, is attached so as to discharge the mist F downward outside the equipment box 51. By attaching the mist discharge port 23 to the mist discharge port 23, it is possible to discharge the mist F outside the equipment box 51 while preventing the mist F generated inside the tank 43 from leaking into the case 2 or the inside of the equipment box 51.

[0028] Furthermore, water conduit 42 may have a backflow prevention structure that prevents mist F from flowing backward through water conduit 42. For example, water conduit 42 may be structured to extend close to the bottom of tank 43 so that tip end (lower end) 42A of water conduit 42 disposed inside tank 43 is positioned below the surface of the dehumidified water W stored in tank 43. This prevents mist F from flowing backward through water conduit 42, thereby suppressing leakage of mist F from electronic dehumidifier 1 into equipment box 51.

[0029] In this way, electronic dehumidifier 1 is configured so that dehumidified water W removed from humid air A1 by dehumidifying unit 3 is atomized by discharge unit 4 and discharged to the outside of equipment box 51. For this reason, electronic dehumidifier 1 can be installed even in places where there is no drainage equipment for draining dehumidified water W. Furthermore, periodic manual drainage of dehumidified water W is no longer necessary.

[0030] Furthermore, unlike conventional electronic dehumidifiers, there is no need to install an external water receiver and heating mechanism outside the equipment box 51. This allows the size of the part installed outside the equipment box 51 to be reduced. Also, since there is no heating mechanism outside the equipment box 51, safety is improved.

[0031] Fig. 3 is a schematic diagram showing the main functional blocks of the electronic dehumidifier 1. Fig. 3 shows the functional blocks related to the control of the exhaust unit 4 of the electronic dehumidifier 1.

[0032] As shown in Figure 3, the electronic dehumidifier 1 is equipped with a control circuit 10 that comprehensively controls the operation of the entire electronic dehumidifier 1. The control circuit 10 controls the operation of both the dehumidification unit 3 and the exhaust unit 4.

[0033] The control circuit 10 includes a water depth determination unit 11 and an appliance control unit 12. The water depth determination unit 11 determines whether the depth of the dehumidified water W in the tank 43 has reached a predetermined upper threshold S1 or lower threshold S2 based on a detection signal obtained from the water depth sensor 44. For example, an upper threshold S1 that defines the upper limit of the depth of the dehumidified water W and a lower threshold S2 that defines the lower limit of the depth are set in the tank 43 in advance. For example, if the depth of the dehumidified water W has increased to the upper threshold S1, the water depth determination unit 11 outputs the determination result to the appliance control unit 12. Furthermore, for example, if the depth of the dehumidified water W has decreased to the lower threshold S2, the water depth determination unit 11 outputs the determination result to the appliance control unit 12.

[0034] 3, the lower limit threshold S2 may be set vertically above the height position of the tip 42A of the water conduit 42. This results in a structure in which the tip 42A remains immersed in the dehumidified water W even when the depth of the dehumidified water W in the tank 43 has decreased to the lower limit threshold S2 (a backflow prevention structure). This prevents the mist F generated in the tank 43 from flowing into the water conduit 42, effectively preventing the backflow of the mist F. However, the upper limit threshold S1 and the lower limit threshold S2 may be set arbitrarily. For example, the lower limit threshold S2 may be set so that the depth of the dehumidified water W is zero.

[0035] The device control unit 12 controls each part of the electronic dehumidifier 1. For example, the device control unit 12 controls the power supply unit 35 to perform power supply control for supplying power to the dehumidifying unit 3 and the exhaust unit 4. The device control unit 12 also controls the piezoelectric vibrator 45 according to the depth of the dehumidified water W accumulated in the tank 43 to perform atomization control for atomizing the dehumidified water W. This atomization control is performed by the device control unit 12 controlling the piezoelectric vibrator 45 based on, for example, a detection signal output by the water depth sensor 44 and a determination result output by the water depth determination unit 11. Details of the atomization control will be described later.

[0036] [Electronic dehumidifier 1 operation] Next, a description will be given of an example of the operation of the electronic dehumidifier 1. The following operation is performed by the control circuit 10 controlling each part of the electronic dehumidifier 1.

[0037] After the electronic dehumidifier 1 starts operating, the control circuit 10 supplies a DC voltage from the power supply unit 35 to the Peltier element 31 and rotates the fan 36 as necessary. By supplying power to the Peltier element 31, the cooling fin 32 side is absorbed (cooled) by the Peltier element 31 and the heat dissipation fin 34 side is heated. Furthermore, the rotation of the fan 36 creates a negative pressure inside the case 2, and humid air A1 is taken into the case 2 through the air intake 21.

[0038] Humid air A1 taken in through intake port 21 first passes through cooling fins 32. As it passes through cooling fins 32, humid air A1 hits cooling fins 32, causing condensation and reducing the moisture content of humid air A1. The dehumidified air then passes through heat dissipation fins 34. As it passes through cooling fins 32, the dehumidified air is heated and its temperature rises, turning it into dry air A2. The dry air A2 is discharged from exhaust port 22 by fan 36.

[0039] Meanwhile, the dehumidified water W condensed on the cooling fins 32 drips into the water receiver 41, passes through the water guide pipe 42 and accumulates in the tank 43. The depth of the dehumidified water W accumulated in the tank 43 is detected by the water depth sensor 44 and output to the control circuit 10. The control circuit 10, which receives the detection signal from the water depth sensor 44, performs the atomization control shown below.

[0040] Fig. 4 is a flowchart showing an example of atomization control for atomizing the dehumidified water W. As shown in Fig. 4, first, the water depth determination unit 11 determines whether the depth of the dehumidified water W accumulated in the tank 43 has increased to an upper limit threshold S1 based on a detection signal obtained from the water depth sensor 44 (step S1). If the depth of the dehumidified water W is equal to or greater than the upper limit threshold S1 (YES in step S1), the water depth determination unit 11 outputs the determination result to the device control unit 12. On the other hand, if the depth of the dehumidified water W is less than the upper limit threshold S1 (NO in step S1), the water depth determination unit 11 repeats the process of step S1.

[0041] Next, when the device control unit 12 acquires the determination result from the water depth determination unit 11, it starts supplying power to the piezoelectric vibrator 45 to generate ultrasonic vibrations U. The piezoelectric vibrator 45 vibrates the surface of the dehumidified water W with the ultrasonic vibrations U, atomizing the dehumidified water W (step S2). As a result, the dehumidified water W turns into mist F, which is sequentially discharged to the outside of the equipment box 51 through the mist discharge port 23. At this time, because the tip 42A of the water conduit 42 is located below the surface of the dehumidified water W as described above, the mist F is prevented from flowing back up the water conduit 42.

[0042] Furthermore, by atomizing the dehumidified water W, the depth of the dehumidified water W in the tank 43 gradually decreases. At this time, the device control unit 12 controls the oscillation frequency and oscillation amplitude of the piezoelectric vibrator 45 according to the depth of the dehumidified water W, based on the detection signal obtained from the water depth sensor 44. By controlling the oscillation frequency and oscillation amplitude of the piezoelectric vibrator 45 in this way according to the change (decrease) in the depth of the dehumidified water W, mist F can be efficiently generated from the surface of the dehumidified water W.

[0043] Next, the water depth determination unit 11 determines whether the depth of the dehumidified water W in the tank 43 has decreased to the lower threshold value S2 based on the detection signal obtained from the water depth sensor 44 (step S3). If the depth of the dehumidified water W is equal to or less than the lower threshold value S2 (YES in step S3), the water depth determination unit 11 outputs the determination result to the equipment control unit 12. On the other hand, if the depth of the dehumidified water W exceeds the lower threshold value S2 (NO in step S3), the water depth determination unit 11 repeats the processing of step S3.

[0044] Next, when the determination result is acquired from the water depth determination unit 11, the device control unit 12 stops supplying power to the piezoelectric vibrator 45. As a result, the device control unit 12 stops atomizing the dehumidified water W (step S4).

[0045] The control circuit 10 repeatedly performs the above-described atomization control flow after starting operation of the electronic dehumidifier 1. This allows the depth of the dehumidified water W to be maintained within the range between the upper threshold value S1 and the lower threshold value S2.

[0046] [Effects of Electronic Dehumidifier 1] As described above, the electronic dehumidifier 1 includes a dehumidifying section 3 that includes a Peltier element 31 that cools the humid air A1 inside the equipment box 51 and dehumidifies the humid air A1, and a discharge section 4 that includes a piezoelectric vibrator 45 that atomizes the dehumidified water W removed from the humid air A1 by the dehumidifying section 3 using ultrasonic vibrations U and discharges the mist F to the outside of the equipment box 51.

[0047] In the electronic dehumidifier 1, the discharge unit 4 atomizes the dehumidified water W using ultrasonic vibrations U and discharges it outside the equipment box 51. Therefore, there is no need to install an external water receiver and heating mechanism outside the equipment box 51 as in the conventional case.

[0048] Therefore, according to this embodiment, it is possible to provide an electronic dehumidifier 1 that can reduce the size of the portion that is installed outside the equipment box 51. Furthermore, since there is no heating mechanism outside the equipment box 51, safety during use of the electronic dehumidifier 1 is improved.

[0049] [Modification] (First Modification) Fig. 5 is a cross-sectional view showing a discharge unit 4A which is a first modified example of the discharge unit 4 shown in Fig. 3. As shown in Fig. 5, the discharge unit 4A is placed inside the tank 43 and further includes a water-absorbing pad 47 which absorbs the dehumidified water W, and the piezoelectric vibrator 45 may atomize the dehumidified water W absorbed by the water-absorbing pad 47.

[0050] The water absorbent pad 47 is made of a water-absorbent material, such as a porous, nonwoven, or mesh-like material, that can absorb the dehumidification water W, and is laid on the bottom surface of the tank 43. In the discharge section 4A, the water absorbent pad 47 laid on the tank 43 is impregnated with the dehumidification water W, so the vertical thickness of the water absorbent pad 47 can be regarded as the depth of the dehumidification water W accumulated in the tank 43. Therefore, the control circuit 10 can atomize the dehumidification water W by operating the piezoelectric vibrator 45 at a constant oscillation frequency and oscillation amplitude that correspond to, for example, the thickness of the water absorbent pad 47. This eliminates the need to control the piezoelectric vibrator 45 in response to changes (decrease) in the depth of the dehumidification water W, as described above, and the control of the piezoelectric vibrator 45 can be simplified.

[0051] Furthermore, since it is no longer necessary to control the piezoelectric vibrator 45 according to the depth of the dehumidified water W, it is no longer necessary to install the water depth sensor 44 for detecting the depth of the dehumidified water W. This makes it possible to omit the water depth sensor 44, thereby simplifying the device configuration of the electronic dehumidifier 1.

[0052] If the water depth sensor 44 is omitted, the control circuit 10 may perform atomization control for atomizing the dehumidified water W at regular intervals regardless of the depth of the dehumidified water W. In other words, in the atomization control flowchart illustrated in Fig. 4, steps S1 and S3 performed by the water depth determination unit 11 may be omitted, and steps S2 and S4 may be repeatedly performed at regular intervals.

[0053] (Second Modification) Fig. 6 is a cross-sectional view showing a discharge unit 4B which is a second modified example of the discharge unit 4 shown in Fig. 3. As shown in Fig. 6, the discharge unit 4B further includes a water-absorbing stick 48 that sucks up the dehumidified water W stored in the tank 43, and the piezoelectric vibrator 45 may atomize the dehumidified water W sucked up by the water-absorbing stick 48.

[0054] The water absorbent stick 48 is made of a water-absorbent material, similar to the above-mentioned water absorbent pad 47. The discharge unit 4B is configured so that the rod-shaped water absorbent stick 48 hangs from the top of the tank 43 to suck up the dehumidified water W, and the sucked up dehumidified water W is atomized by the piezoelectric vibrator 45. In the discharge unit 4B, for example, the lower end 48A of the water absorbent stick 48 is immersed in the dehumidified water W, and the dehumidified water A sucked up from the lower end 48A side is atomized by the piezoelectric vibrator 45 attached to the upper end 48B of the water absorbent stick 48.

[0055] According to the discharge unit 4B, the dehumidified water W sucked up from the tank 43 by the water absorption stick 48 is atomized, so the capacity of the tank 43 can be reduced. This increases the degree of freedom in designing the arrangement, shape, etc. of the tank 43. Furthermore, as with the discharge unit 4A described above, it is possible to simplify the control of the piezoelectric vibrator 45 and omit the water depth sensor 44.

[0056] The discharge section 4B may include a storage section 49 for storing the piezoelectric vibrator 45 on the upper end 48B side of the water absorbent stick 48. The interior of this storage section 49 is connected to the mist discharge outlet 23, and the mist F generated inside the storage section 49 is discharged to the outside of the equipment box 51 through the mist discharge outlet 23. In this way, the inside of the storage section 49 may be an independent space partitioned off from the inside of the tank 43. This allows the mist F generated inside the storage section 49 to be efficiently discharged to the outside of the equipment box 51.

[0057] (Third Modification) Fig. 7 is a cross-sectional view showing discharge section 4C, which is a third modified example of discharge section 4 shown in Fig. 3. As shown in Fig. 7, discharge section 4C may have check valve 42B installed midway through water conduit 42 to prevent mist F from flowing backward through water conduit 42. Check valve 42B allows fluid (dehumidified water W) to pass only in the direction from water receiver 41 toward tank 43, and does not allow fluid (dehumidified water W and mist F) to pass in the direction from tank 43 toward water receiver 41. Discharge section 4C prevents mist F from flowing backward through water conduit 42, thereby suppressing leakage of mist F from electronic dehumidifier 1 into equipment box 51.

[0058] The discharge section 4C has a backflow prevention structure that includes both a structure in which the tip 42A of the water conduit 42 is located below the surface of the dehumidified water W, and a structure in which a check valve 42B is installed in the water conduit 42. This more reliably prevents the mist F from flowing back through the water conduit 42. However, the discharge section 4C may have a structure that includes either one of the backflow prevention structures.

[0059] 〔summary〕 The electronic dehumidifier according to aspect 1 of the present disclosure is an electronic dehumidifier that dehumidifies the inside of an equipment box, and includes a cooling unit (Peltier element 31) that cools the air (humid air A1) inside the equipment box and a dehumidifying unit that dehumidifies the air, and an atomizing unit (piezoelectric vibrator 45) that atomizes the dehumidified water removed from the air by the dehumidifying unit using ultrasonic vibrations and a discharge unit that discharges the atomized water to the outside of the equipment box.

[0060] In this configuration, the discharge unit atomizes the dehumidified water using ultrasonic vibrations and discharges it outside the equipment box. Therefore, there is no need to install an external water receiver or heating mechanism outside the equipment box, as in the past. Therefore, with this configuration, the parts installed outside the equipment box can be made smaller. Furthermore, since there is no heating mechanism outside the equipment box, safety is improved.

[0061] The electronic dehumidifier according to aspect 2 of the present disclosure is in aspect 1, and further includes a case that is installed inside the equipment box and has an air intake port for drawing in the air and a mist outlet port for discharging the atomized water, and the dehumidifying unit and the exhaust unit may be housed in the case.

[0062] According to the above configuration, the dehumidifying section and the exhaust section are housed in the case to form a single unit, which makes it easy to install the electronic dehumidifier in the equipment box.

[0063] In an electronic dehumidifier according to aspect 3 of the present disclosure, in aspect 1 or 2, the discharge section is arranged below the dehumidifying section and further includes a water receiver for receiving the dehumidified water, and a tank for storing the dehumidified water received by the water receiver, and the atomization section may atomize the dehumidified water inside the tank.

[0064] According to this configuration, the dehumidified water removed from the air by the dehumidifying section is collected in the tank, and can be efficiently atomized by the atomizing section.

[0065] In an electronic dehumidifier according to aspect 4 of the present disclosure, in aspect 3, the discharge section may further include a water conduit connected to the water receiver and guiding the dehumidified water received by the water receiver to the tank, and the water conduit may have a backflow prevention structure that prevents the atomized water from flowing back through the water conduit.

[0066] According to the above configuration, it is possible to prevent the atomized water from leaking from the electronic dehumidifier into the inside of the equipment box.

[0067] In an electronic dehumidifier according to aspect 5 of the present disclosure, in aspect 3 or 4, the discharge section may further include an absorbent pad placed inside the tank and absorbing the dehumidified water, and the atomization section may atomize the dehumidified water absorbed by the absorbent pad.

[0068] According to the above configuration, the thickness of the water-absorbing pad laid on the tank can be regarded as the depth of the dehumidified water accumulated in the tank, so that it is not necessary to control the atomization unit according to the water depth, and this control can be simplified.Furthermore, it is not necessary to install a water depth sensor for detecting the water depth, and the device configuration of the electronic dehumidifier can be simplified.

[0069] In an electronic dehumidifier according to aspect 6 of the present disclosure, in aspect 3 or 4, the discharge unit may further include an absorbent stick that sucks up the dehumidified water stored in the tank, and the atomization unit may atomize the dehumidified water sucked up by the absorbent stick.

[0070] In this configuration, the dehumidifying water is sucked up from the tank by the water-absorbing stick and atomized, so the tank capacity can be reduced. Therefore, this configuration increases the degree of design freedom in terms of the tank arrangement, shape, etc.
