As shown in FIG. 1 , the heat exchange ventilator 1 includes a blower unit 3 having a heat exchange element 2 , a humidification unit 5 having a humidification section 4 , and an electrolysis unit 7 having electrodes 6 .

First, the configuration of the blower unit 3 will be described with reference to FIGS. 1 to 3. FIG.

FIG. 1 is a perspective view showing the front side of a heat exchange ventilator according to Embodiment 1 of the present invention. FIG. 2 is a perspective view showing the rear side of the heat exchange ventilator according to Embodiment 1 of the present invention. FIG. 3 shows a schematic cross-sectional view of a heat exchange ventilator according to Embodiment 1 of the present invention.

The blower unit 3 includes a main body case 36, an air supply fan 8, an exhaust fan 9, an indoor air inlet 10, an outdoor air inlet 11, an air outlet 12, an air inlet 13, and an air supply air passage 14. , and an exhaust air passage 15 .

The body case 36 has a box shape and is used, for example, while being placed on the floor.

An external air intake port 11 , an air supply port 13 , an indoor air intake port 10 , and an exhaust port 12 are provided on, for example, the top surface of the main body case 36 .

The outside air intake port 11 is provided at a position adjacent to the indoor air intake port 10 and the exhaust port 12 . Also, the air supply port 13 is provided at a position adjacent to the indoor air suction port 10 and the exhaust port 12 . That is, the indoor air intake port 10 and the air exhaust port 12 are provided at positions adjacent to the outside air intake port 11 and the air supply port 13, respectively.

The external air intake port 11, the air supply port 13, the room air intake port 10, and the exhaust port 12 are shaped so that a duct can be connected to each. A duct connected to the outside air intake port 11 and the exhaust port 12 is routed to the outer wall surface of the building to communicate with the outdoor air outside the building. A duct connected to the air supply port 13 and the room air suction port 10 communicates with the ceiling surface or the wall surface of the room to communicate with the room air.

The body case 36 has a heat exchange element 2, an air supply fan 8, an exhaust fan 9, an air supply airway 14, and an air exhaustion airway 15 inside.

The supply air path 14 draws in outdoor air (supply air) from the outside air suction port 11 by the supply fan 8, passes through the heat exchange element 2, supplies the indoor air from the air supply port 13 via the humidification unit 5. It is an airway. That is, the air sucked from the outside air intake port 11 by the air supply fan 8 is blown out from the air supply port 13 after passing through the heat exchange element 2 and flows into the humidification unit 5 .

In the exhaust air passage 15 , the exhaust fan 9 sucks the indoor air from the indoor air suction port 10 and blows the indoor air through the heat exchange element 2 to the exhaust port 12 . The indoor air that has passed through the exhaust air passage 15 is exhausted to the outside.

The heat exchange element 2 is provided at a position where the supply air passage 14 and the exhaust air passage 15 intersect. The heat exchange element 2 is provided below the air supply fan 8 or the exhaust fan 9 .

The heat exchange element 2 has a humidity recovery (humidity exchange) function of recovering (exchanging) the humidity of the air sucked by the air supply fan 8 and passing through the inside of the blower unit 3 (in particular, the air supply air passage 14). there is The heat exchange element 2 is, for example, a total heat exchange element, but may be a desiccant type or heat pump type heat exchanger having a function of recovering (exchanging) temperature.

The heat exchange element 2 performs humidity exchange between the air passing through the exhaust air passage 15 and the air passing through the supply air passage 14 . The heat exchange element 2 may have a function of recovering (exchanging) temperature as well as humidity. Thereby, more comfortable air can be supplied indoors.

Also, the blower unit 3 may have a control section (not shown). The controller controls the operation of the air supply fan 8 and the operation of the exhaust fan 9 . As a result, even when the humidifying unit 5 is not in operation, the humidity of the air supplied to the room can be controlled by recovering the humidity with the heat exchange element 2 of the blower unit 3 .

In this embodiment, the blower unit 3 is placed on the floor and used, but the blower unit 3 may be configured such that the main body case 36 is installed sideways. That is, the air supply port 13 and the like of the blower unit 3 may be provided not on the top surface but on the side surface. At this time, the air path is configured such that the air is sucked in from the side of the main body case 36 and is blown out from the side of the main body case 36 . As a result, the blower unit 3 can be installed, for example, above the ceiling or under the floor, and the humidification unit 5 can be connected to various blower units 3 .

Further, the air whose humidity has been collected by the heat exchange element 2 may be bypassed so as not to pass through the humidification unit 5 and supplied into the room. As a result, for example, when only the blower unit 3 is operated without the humidifying unit 5, the air whose humidity has been recovered by the heat exchange element 2 can be efficiently supplied into the room.

Next, connection between the humidifying unit and the blower unit will be described. The details of the configuration of the humidifying unit will be described later.

As shown in FIG. 2 , the humidifying unit 5 is installed on the top surface of the blower unit 3 . For example, the humidification unit 5 and the blower unit 3 are connected by a support portion 46 having a leg portion 46a and a base portion 46b. At this time, the leg portion 46a and the blower unit 3 are fixed, and the pedestal portion 46b and the humidifying unit 5 are fixed. That is, as shown in FIG. 2, the humidifying unit 5 is placed on the support portion 46 (particularly, the pedestal portion 46b). As a result, since the humidifying unit 5 and the blowing unit 3 are provided separately, for example, the conditions such as routing of the duct connected to the top surface of the blowing unit 3 are relaxed, and the workability of the humidifying unit 5 and the blowing unit 3 is improved. improves.

Via the duct 45, the air supply port 13 of the blower unit 3 and the suction port 16 of the humidification unit 5 communicate with each other. That is, the duct 45 is connected to the air supply port 13 and the suction port 16 . As a result, the air blown out from the air supply port 13 by the air supply fan 8 of the blower unit 3 passes through the duct 45 and flows into the humidification unit 5 from the suction port 16 . Since a duct can be connected to the suction port 16 , the humidifying unit 5 can be installed additionally to the blower unit 3 , that is, can be retrofitted, and can be adapted to various blower units 3 .

The blower unit 3 is provided upstream of the humidifier unit 5 in the flow of air passing through the humidifier unit 5 and the blower unit 3 . In other words, the humidification unit 5 is provided downstream of the blower unit 3 . At this time, since the air whose humidity has been recovered by the heat exchange element 2 flows into the humidifying unit 5, the humidity can be controlled more efficiently. In addition, by performing humidity control at two locations, the heat exchange element 2 and the humidification unit 5, a sufficient amount of humidification can be ensured even when a heater or the like is not installed in the heat exchange element 2 or the humidification unit 5. . In addition, energy saving can be achieved by eliminating the need for a heater for securing the humidification amount.

Note that the humidifying unit 5 and the blower unit 3 may be detachable. As a result, the humidifying unit 5 and the air blowing unit 3 can be removed separately, thereby improving maintainability.

Next, the configuration of the electrolysis unit 7 will be described with reference to FIG. FIG. 4 is a perspective view showing the electrolysis unit 7. FIG.

The electrolysis unit 7 comprises electrodes 6 for electrically treating water. The electrode 6 is composed of a first electrode 6a and a second electrode 6b and is submerged in water inside the electrolysis unit 7 . The first electrode 6a and the second electrode 6b are connected to an external power source (not shown).

The electrolysis unit 7 is connected to the humidification unit 5 via a pipe 50 or the like.

Here, a method for generating electrolyzed water in the electrolysis unit 7 will be described in detail with reference to FIG.

Chloride ions are generated by putting the electrolysis promoting tablets into the electrolysis unit 7 . Then, by energizing the electrodes 6, a voltage is applied to the first electrode 6a and the second electrode 6b, and the generated chloride ions are electrochemically decomposed by the electrodes 6 to produce hypochlorous acid water ( Electrolyzed water) is generated. Then, the hypochlorous acid water generated by the electrolysis unit 7 is supplied to the humidifying section 4 . The humidifying unit 4 humidifies the air supplied into the room using the supplied hypochlorous acid water (electrolyzed water). A humidification method by the humidification unit 4 will be described later.

Here, the electrolysis-enhancing tablet is, for example, a sodium chloride tablet.

According to such a configuration, by humidifying the indoor air using the hypochlorous acid water, the indoor air can be disinfected and deodorized in addition to the humidification.

Further, the electrolysis unit 7 may be configured to include an electrolysis acceleration tablet loading device (not shown). As a result, the electrolysis-promoting tablet can be automatically fed. Also, at this time, a sensor (not shown) for detecting the pollution state of the indoor air may be provided separately. As a result, the electrolysis-enhancing tablet inserting device inserts the electrolysis-enhancing tablet based on the indoor air contamination state detected by the sensor, so that the humidification operation using the hypochlorous acid water can be performed efficiently.

The shape of the electrolysis unit 7 is not limited to the illustrated one, and may be appropriately set according to the connection method with the humidification unit 5 and the blower unit 3 .

Next, the configuration of the humidifying unit will be described with reference to FIGS. 5 to 7. FIG.

FIG. 5 is a perspective view showing the front side of the humidifying unit according to this embodiment. FIG. 6 is a perspective view showing the back side of the humidifying unit according to this embodiment. FIG. 7 shows a schematic cross-sectional view of a humidifying unit according to this embodiment.

As shown in FIGS. 5 and 6, the humidifying unit 5 includes an inlet 16, an outlet 17, an inner cylinder 19, an outer cylinder 23, and a water receiver . The humidification unit 5 is configured as a cylindrical container.

The air outlet 17 is an opening through which the air that has passed through the inside of the humidifying unit 5 is blown out, and is provided on the upper surface of the humidifying unit 5 . Also, the outlet 17 is formed in a region partitioned by an inner cylinder 19 and an outer cylinder 23, which will be described later. For example, the outlet 17 is provided around the inner cylinder 19 on the upper surface of the humidifying section 4 . Furthermore, the blowout port 17 is provided so as to be positioned above the suction port 16 . Moreover, the outlet 17 has a shape to which a cylindrical duct can be connected.

The air taken in (sucked in) from the suction port 16 is blown out (flowed out) from the blower port 17 .

The inner cylinder 19 is arranged near the center inside the humidifying section 4 . Further, as shown in FIG. 7, the inner cylinder 19 is formed in a hollow cylindrical shape having a ventilation port 21 that opens downward in the substantially vertical direction. The outer cylinder 23 is formed in a cylindrical shape and arranged so as to enclose the inner cylinder 19 .

A water receiving portion 26 is provided below the humidifying unit 5 . The water receiving portion 26 can store liquid that has not been completely stored in the water storing portion 24, which will be described later. As a result, even if excessive water is supplied or a problem occurs in the drain port 25 (see FIG. 7) or the like, the liquid can be prevented from overflowing into the house, the blower unit 3, and the like.

The shape of the water receiving portion 26 is not limited to the shape illustrated in FIG. Also, the humidifying unit 5 may not include the water receiver 26 .

As shown in FIG. 7 , the humidifying unit 5 has a humidifying section 4 , an inner cylinder air passage 18 , a suction communication air passage 20 , an outer cylinder air passage 22 and a water storage portion 24 .

The suction communication air passage 20 is a duct-shaped air passage that communicates the suction port 16 and the inner cylinder 19, and the air sucked from the suction port 16 reaches the inner cylinder 19 through the suction communication air passage 20. It is configured.

The inner cylinder air passage 18 passes through an opening (ventilation port 21) provided at the lower end of the inner cylinder 19 and an outer cylinder air passage 22 (indicated by the dashed arrow in FIG. 7) provided outside the inner cylinder 19. road).

The outer tube air passage 22 is formed between the inner tube 19 and the outer tube 23 . A portion of the outer tube air passage 22 is formed in a region partitioned by the inner tube 19 and the outer tube 23 .

The water storage part 24 is provided in the lower part of the humidification unit 5 and stores liquid. Moreover, the water storage part 24 is formed in a substantially mortar shape, and the side wall of the water storage part 24 is connected to the lower end of the outer cylinder 23 to be integrated therewith. The liquid stored in the water reservoir 24 is, for example, water or hypochlorous acid water. Hereinafter, the liquid stored in the water storage part 24 is assumed to be water for the purpose of explanation.
The humidifying unit 5 is provided with a water supply port 29 for supplying water to the water reservoir 24 and a drain port 25 for discharging water from the water reservoir 24 in order to continuously make the water finer. The water supply port 29 is provided in the outer cylinder 23, and water is stored up to the water surface 44 shown in FIG. Moreover, the drain port 25 is provided in the bottom surface of the mortar-shaped water storage portion which is the lower portion of the water storage portion 24 . The water supply port 29 is connected to a water supply pipe 30, and the water supply pipe is connected to, for example, water supply equipment such as a water supply or a water supply pump of a house or facility via opening/closing means such as an electromagnetic valve. Also, the drain port 25 is connected via a drain pipe 28 to a drain facility such as a drain port provided in a house or facility.

The humidifying section 4 has a suction pipe 32 , a rotating plate 33 and a motor 34 . The humidifying section 4 is provided inside the inner cylinder 19 , that is, at a position covered by the inner cylinder 19 .

The suction pipe 32 sucks up water from the water reservoir 24 by rotating. The suction pipe 32 is formed in the shape of a hollow truncated cone, and is provided so that the tip of the smaller diameter side is below the water level of the water stored in the water reservoir 24 . The rotating plate 33 is formed in a doughnut-shaped disc shape with an open center, and is arranged around the larger diameter side of the suction pipe 32 , in other words, around the upper portion of the suction pipe 32 . A plurality of openings are provided in the side surface of the suction pipe 32 with a large diameter, and the water sucked up is supplied to the rotating plate 33 through the openings. Then, the rotating plate 33 discharges the water sucked up by the suction pipe 32 in the rotating surface direction. A motor 34 rotates the suction pipe 32 and the rotary plate 33 .

Furthermore, the humidification unit 5 may be equipped with the humidification control part 27 on the side surface (refer FIG. 1). The humidification control section 27 controls the amount of humidification by controlling the operation of the humidification unit 5 , especially the humidification section 4 . As a result, the humidifying unit 5 can operate in conjunction with the air blowing unit 3, or can operate independently without interlocking.

Note that the position where the humidification control unit 27 is provided is not limited to the position shown in FIG. 1 and the like. Alternatively, the humidifying unit 5 may be configured to be controlled by a control unit that controls the blower unit 3 without the humidification control unit 27 .

The humidification unit 5 may also include a water storage tank 40 (see FIG. 1) that stores the electrolyzed water (for example, hypochlorous acid water) generated by the electrolysis unit 7 . Since the humidifying unit 5 includes the water storage tank 40 , the generated electrolyzed water can be stored in the water storage tank 40 . Thereby, when there is electrolyzed water in the water storage tank 40 and there is no need to generate electrolyzed water, that is, when there is no need to operate the electrolysis unit 7, the energization to the electrodes 6 can be stopped. As a result, energy saving can be improved.

The operation of the humidifying unit 5 will be described below with reference to FIG.

First, water is supplied from the water supply port 29 to the water reservoir 24 from a water supply facility (not shown), and the water is stored in the water reservoir 24 . Air sucked into the humidifying unit 5 from the suction port 16 by the blower unit 3 passes through the suction communication air passage 20, the inner cylinder air passage 18, the humidifying section 4, and the outer cylinder air passage 22 in this order. is blown out toward the outside, for example, into the room. At this time, the water droplets generated by the humidifying section 4 come into contact with the air passing through the inner cylinder air passage 18, and the water droplets evaporate, thereby humidifying the air. Moreover, the water stored in the water storage part 24 is discharged from the drain port 25 after a predetermined time has passed.

The detailed operation will be explained.

Air taken into the inner tube of the inner tube air path 18 from the suction port 16 through the suction communication air path 20 passes through the humidifying section 4 . When the suction pipe 32 and the rotary plate 33 are rotated by the operation of the motor 34 , the water stored in the water storage portion 24 rises along the inner wall surface of the suction pipe 32 . The rising water is stretched along the surface of the rotating plate 33 and discharged as fine water droplets from the outer peripheral edge of the rotating plate 33 toward the direction of the rotating surface. The discharged water droplets collide with the inner wall surface of the inner cylinder 19 and are crushed to become finer water droplets. The water droplets discharged from the rotating plate 33 and the water droplets collided with the inner wall surface of the inner cylinder 19 and crushed come into contact with the air passing through the inner cylinder 19, vaporize the water droplets, and humidify the air. Some of the generated water droplets do not evaporate, but since the humidifying unit 4 is arranged so as to be covered with the inner cylinder 19 , the water droplets that have not vaporized adhere to the inner surface of the inner cylinder 19 and to fall.

Then, air containing water droplets (humidified air) is blown out from a ventilation port 21 provided at the lower end of the inner cylinder 19 toward a water reservoir 24 provided below. Then, it flows toward the outer tube air passage 22 formed between the inner tube 19 and the outer tube 23 . Here, since the air passing through the outer cylinder air passage 22 is blown upward in the vertical direction, the blowing direction of the air flowing downward in the inner cylinder air passage 18 changes to the opposite direction.

At this time, the water droplets blown out together with the air from the ventilation port 21 cannot follow the air flow due to their inertia, and adhere to the water surface of the water reservoir 24 or the inner wall surface of the outer cylinder 23 . This effect increases as the weight of the water droplet increases. That is, the larger the diameter of the water droplet, which is less likely to vaporize, the greater the effect. Therefore, large droplets can be separated from the flowing air.

Air that has flowed from the inner cylinder air passage 18 into the outer cylinder air passage 22 through the ventilation port 21 flows upward through the outer cylinder air passage 22 . Then, the air is blown out from the outlet 17 . At this time, some of the water droplets fall into the reservoir 24 due to gravity, or adhere to the outer wall of the inner cylinder 19 or the inner wall of the outer cylinder 23 . Water droplets adhering to the outer wall of the inner cylinder 19 and the inner wall of the outer cylinder 23 flow along the outer wall surface of the inner cylinder 19 and the inner wall surface of the outer cylinder 23 and fall into the water reservoir 24 .

As described above, the humidifying unit 5 of the present invention can humidify the air by miniaturizing the liquid. The humidification unit 5 can control the amount of humidification by the rotation speed of the rotating plate 33 . As a result, for example, the heat exchange element 2 is such that the amount of humidification is fixed at a constant value depending on the state of the passing air, the humidity recovery efficiency, etc., and even if it is difficult to control the amount of humidification, the humidification unit Humidity can be controlled more appropriately by performing the humidification amount control by 4 together. That is, with the heat exchange element 2 and the humidifying unit 5 having a variable humidity amount, the overall humidity of the room can be more accurately set to the target humidity.

Here, the liquid to be humidified by the humidifying unit 5 may be hypochlorous acid water as described above. Specifically, the hypochlorous acid water generated by the electrolysis unit 7 may be supplied to the humidification unit 5, and the hypochlorous acid water may be used to humidify the air. As a result, the air supplied to the room can be disinfected and deodorized.

Furthermore, the liquid used for humidification in the humidification unit 5 may be another aqueous solution obtained by electrolyzing water and acquiring useful functions. Specifically, alkaline ionized water (alkaline electrolyzed water), weakly acidic electrolyzed water, slightly acidic electrolyzed water, ozone water, electrolyzed hypochlorite water, hydrogen water, and the like may be used. Further, for example, when alkaline ionized water is used, the electrolytic unit 7 serving as an electrolytic cell may be of a two-chamber type having a diaphragm. Thereby, humidification, sterilization, and deodorization of the air supplied to the room can be performed according to the characteristics of each electrolyzed water.

Moreover, the water supplied to humidification by the humidification unit 5 is not limited to water directly supplied from the water supply, but may be water after passing through a filtering member such as a filter provided in the humidification unit 5 . This makes it more difficult for scales to adhere to the interior of the humidifying unit 5 .

Next, the relationship between the operation of the humidification unit 5 and the operation of the blower unit 3 will be described.

The humidification operation by the humidification section 4 may be performed in conjunction with the operation of the blower unit 3 . Thereby, humidity control can be performed more appropriately.

For example, when the controller of the blower unit 3 determines that further humidification is necessary during operation in which only the humidity is controlled by the heat exchange element 2, the controller of the blower unit 3 controls the humidification controller 27. to start the humidification operation. After receiving this instruction, the humidification control section 27 instructs the humidification section 4 to start operation. This makes it possible to control the amount of humidification, that is, the indoor humidity, more appropriately and quickly.

The method of interlocking is not limited to the one described above, and an appropriate control method may be appropriately adopted in order to optimally control the indoor humidity according to the number of rooms in the house and user's preference. Further, the operation of the humidification unit 5 may be controlled by the humidification control section 27 or the control section of the blower unit 3 .

Furthermore, the humidification operation by the humidification section 4 may be performed independently of the humidity collection by the heat exchange element 2 of the blower unit 3 as described above. This makes it possible to control the humidification of the air supplied to the room regardless of whether or not the heat exchange element 2 is performing humidity recovery. Further, the amount of humidification can be increased by operating the humidifying section 4 without increasing the air volume of the blower unit 3. - 特許庁

Note that the electrolysis unit 7 may be separate from the humidification unit 5 . Since the electrolysis unit 7 and the humidification unit 5 are separated from each other, maintenance of the electrolysis unit 7 and the humidification unit 5 can be performed separately, thereby improving maintainability.

Also, the humidifying unit 5 may be provided with an eliminator. The eliminator collects large water droplets among the water droplets crushed by the humidifying section 4 . As a result, it is possible to prevent large water droplets from blowing out from the blowout port 17, thereby reducing discomfort to the user. The eliminator is provided in the inner cylinder 19 so as to cover the vicinity of the outlet 17 and the humidifying section 4, for example.

Furthermore, the outlet 17 may be provided not on the top surface of the humidifying unit 5 but on the side surface. As a result, the humidified air is blown out from the side surface of the humidifying unit 5, so that the humidifying unit 5 can be installed in a place where it cannot be installed in the case of blowing from above. versatility is improved.

Also, the arrangement of the outside air inlet 11, the air inlet 13, the room air inlet 10, and the air outlet 12 in the blower unit 3 is an example, and may vary depending on the type of the blower unit 3, the place where the blower unit 3 is installed, and the like. can be set as appropriate.

Furthermore, in the present embodiment, the humidification unit 5 is installed in the blower unit 3 via the support portion 46, but the connection method between the humidification unit 5 and the blower unit 3 is not limited to this. and the blower unit 3 should be communicated with each other.
