To achieve this object, the humidifier of the present invention comprises: an indoor air flow path for discharging indoor air flowing from the indoor to the indoor again; a humidification rotor composed of a humidification region provided on the indoor air flow path to pass the indoor air, an adsorption region for adsorbing moisture to be supplied to the humidification region, and an adsorbent that alternately passes through the humidification region and the adsorption region by rotation and adsorbs moisture in the adsorption region and evaporates the adsorbed moisture in the humidification region; a humidifying air flow path provided to pass through the adsorption region to flow humidifying air to be supplied with moisture to the adsorption region; a humidifying section for supplying moisture to the humidified air flowing in the humidified air flow path.
Description
Technical Field
The present invention relates to a humidifier, and more particularly, to a humidifier for supplying moisture to indoor air.
Background
A humidifier is an apparatus that artificially generates moisture and sprays the moisture in order to increase the humidity in a room.
As such a conventional humidifier, there are known: a heating humidifier that sprays water vapor generated by heating water stored in a water tank to a predetermined temperature into a room; an ultrasonic humidifier for spraying water particles, which are made fine by ultrasonically vibrating water stored in a water tank, into a room; the vaporizing humidifier vaporizes water adhering to the surface of the humidifying filter by blowing air by spraying water onto the wet porous filter or rotating the disc type humidifying filter in a state where a part of the filter is immersed in a water tank.
In the conventional humidifier, scale or scale is generated in the humidifying filter or the water tank as the humidifier is repeatedly operated. When tap water containing metal ions (calcium ions, magnesium ions, and the like) is used as a substance for humidifying air, the metal ions contained in the tap water chemically react with the air in the process of the tap water contacting the air. Such scale accumulates over time in the humidifying filter or the water tank, and there is a problem that the performance of the humidifier is reduced.
Further, in the conventional humidifier in which the outside air can be passed through the humidifying device, even if the humidifier includes an air cleaning filter, a sterilizing device, or the like for filtering contaminants, there is a problem that bacteria may grow in a flow path and a humidifying filter, which are always exposed to moisture, when the humidifier is used without replacing consumables such as the filter or when the humidifier is not regularly cleaned.
Further, since the water contaminated with bacteria is sprayed into a room without being sterilized, it is extremely harmful to human bodies (particularly, human bodies of patients and infants), and there is a problem that even when sterilized, odor remaining in the water may be diffused into the room during humidification.
Further, a desorption (Desiccant) humidifier is known as a conventional humidifier. The adsorption humidifier can realize humidification without water supply by adsorbing moisture of outside air using an adsorbent and then regenerating the adsorbed moisture using heat to supply the moisture to a room, and has an advantage that the interior of the humidifier is relatively sanitary.
However, the conventional adsorption humidifier has a large volume compared to the humidification capacity, and the humidification capacity varies greatly depending on the temperature and humidity of the outside air, and a large amount of humidification is required in countries having a low temperature and a low absolute humidity in winter, and in this case, there is a problem that the adsorption humidifier having a relatively weak humidification capacity cannot be commercialized.
Korean authorized utility model No. 20-468403 is disclosed as an example of a conventional disc-type vaporizing humidifier.

Detailed Description
Hereinafter, the configuration and operation of the preferred embodiment of the present invention will be described in detail with reference to the drawings.
< first embodiment >
A humidifier according to a first embodiment will be described with reference to fig. 1 and 2.
The humidifier according to the present invention includes: an indoor air flow path 150 for discharging indoor air flowing in from the room into the room again; a humidification rotor 200 composed of a humidification region 210 provided on the indoor air flow path 150 to pass the indoor air therethrough and an adsorption region 220 for adsorbing moisture to be supplied to the humidification region 210; a humidified air flow path 350 through which humidified air to be supplied with moisture to the adsorption region 220 flows; a humidifying section 330 for supplying moisture to the humidified air flowing in the humidified air flow path 350; a control unit (not shown) for controlling the rotation of the humidifying rotor 200 and the moisture supplied from the humidifying unit 330.
The indoor air flow path 150 includes a first indoor air flow path 151 connected to an inlet end of the humidification region 210 to form a flow path into which the indoor air flows, and a second indoor air flow path 152 connected to an outlet end of the humidification region 210 to form a flow path through which the indoor air is discharged.
The first indoor air flow path 151 is provided with a filter 110, a heat recovery heat exchanger 120, a first blower 130, and a heater 140 in this order. One side and the other side of the heat recovery heat exchanger 120 are connected to a first indoor air flow path 151 and a second indoor air flow path 152, respectively.
The filter 110 filters foreign substances contained in the indoor air flowing into the indoor air flow path 150.
The first blower 130 provides suction force for sucking indoor air into the indoor air flow path 150, and may be provided in the first indoor air flow path 151 or the second indoor air flow path 152.
The heater 140 heats the indoor air passing through the first indoor air flow channel 151 and supplies the heated air to the humidification region 210 of the humidification rotor 200. In the humidification region 210, the amount of moisture evaporation is increased by the heated air, and thus the humidification capability can be improved.
The air passing through the humidification region 210 is heated air, and the air passing through the humidification region 210 is also slightly high in temperature. Therefore, the heat recovery heat exchanger 120 exchanges heat between the high temperature air flowing through the second indoor air flow path 152 and the low temperature air flowing through the first indoor air flow path 151, and the air flowing from the indoor is once preheated by the heat recovery heat exchanger 120 and then flows to the heater 140, so that power consumption of the heater 140 for heating the indoor air can be reduced.
The humidifying rotor 200 is equipped with an adsorbent for adsorbing moisture of the humidified air in the inside thereof. The humidification rotor 200 is divided into an adsorption region 220 for adsorbing moisture of the humidified air by the adsorbent and a humidification region 210 for humidifying the indoor air by evaporating the moisture adsorbed in the adsorption region 220.
The humidifying rotor 200 is rotated about a centrally disposed shaft by a driving unit (not shown).
As shown in fig. 1, if the humidifying rotor 200 rotates in a clockwise direction, the moisture of the humidified air is absorbed by the adsorbent in the adsorption region 220, and if the humidifying rotor 200 further rotates, the adsorbed moisture is evaporated by the indoor air heated by the heater 140 while passing through the humidification region 210, thereby supplying the moisture to the indoor air.
Since the indoor air passing through the humidification region 210 is discharged to the indoor after the temperature thereof is lowered while passing through the heat recovery heat exchanger 120, the comfort of the indoor environment can be improved due to the discharge of the relatively low-temperature air.
In addition, the surface of the adsorbent may be coated with a polymeric desiccant. The Polymer Desiccant (Desiccant Polymer) is an electrolyte Polymer substance, which is ionized when it comes into contact with moisture, and when moisture comes into contact with the adsorbent of the adsorption region 220, bacteria are removed from the adsorbent by an osmotic pressure phenomenon due to a difference in ion concentration, thereby generating an antibacterial effect. Further, ammonia, hydrogen sulfide, or the like, which generates an odor, also adheres to the polymer desiccant ionized into polar molecules, thereby generating a deodorizing effect.
The humidified air flow path 350 includes a second blower 310, a filter 320, a humidifying unit 330, and a droplet separator 340.
The second blower 310 is provided in the humidified air flow path 350 to flow humidified air toward the inlet end of the adsorption region 220.
The filter 320 is provided between the outlet end of the adsorption region 220 and the humidifying part 330, thereby filtering foreign substances contained in the humidified air flowing in the humidified air flow path 350. Foreign substances may be included in the indoor air passing through the humidification region 210, and if the adsorbent rotates to the adsorption region 220 after the adsorption region 220 adsorbs the foreign substances, the humidification air passes through the adsorption region 220 while allowing the foreign substances to flow into the humidification air flow path 350. These foreign substances are filtered by the filter 320, so that the foreign substances can be removed from the indoor air and prevented from flowing into the humidifying part 330.
Referring to fig. 2, the humidifying part 330 is composed of: a humidification tub 331 having an inner space 331a connected to the humidification air flow path 350 in a communicating manner; a humidification filter 332 provided in the internal space 331a of the humidification tub 331; a supply water tank 335 for supplying water to the humidification tub 331; a drain water tank 338 for storing water drained from the humidification tub 331; a supply valve 334 provided in a supply water pipe 333 connecting the humidification tub 331 and the supply water tank 335; a drain valve 337 provided in a drain pipe 336 connecting the humidification tub 331 and the drain water tank 338.
Inside the humidification tub 331, water is filled to a predetermined level, and a portion of the humidification filter 332 provided as a lower end is immersed in the water. The humidification filter 332 may have the same structure as that of the vaporization humidifier disclosed in the related art, and the humidification filter 332 may be rotated by a driving unit (not shown).
After the humidified air having passed through the adsorption region 220 flows into the internal space 331a of the humidification tub 331, the water attached to the surface of the humidification filter 332 evaporates to receive the moisture, and the humidified air flows through the humidified air flow path 350 to the inlet end of the adsorption region 220.
Although the above illustrates the case where the humidification filter 332 is partially immersed in water, a configuration may be adopted in which an injection unit for injecting water to the humidification filter 332 is provided, and the humidification filter 332 is wetted with the water injected from the injection unit.
A water level sensing sensor (not shown) for sensing the water level of the humidification tub 331 may be provided, and the supply valve 334 and the supply water tank 335 for supplying the water to the humidification tub 331 function as water supply parts 334 and 335. Accordingly, the supply of water performed by the water supply parts 334 and 335 is controlled according to the water level measured at the water level sensing sensor, so that the degree to which the humidifying filter 332 is immersed in water can be adjusted to adjust the amount of humidification.
In the case where the humidification filter 332 is provided with an ejection unit that ejects water, the amount of humidification can be adjusted by adjusting the ejection amount of the ejection unit.
The supply valve 334 is opened and closed to supply water from the supply tank 335 to the humidification tub 331, and the drain valve 337 is opened and closed to drain water from the humidification tub 331 to the drain tank 338.
By providing the humidifying unit 330 having such a configuration, the amount of humidification can be adjusted, and the humidifying capability can be improved, so that a comfortable indoor environment can be created.
Although the case where the supply water tank 335 and the drain water tank 338 are separately configured has been described above, the supply water tank 335 and the drain water tank 338 may be configured to be integrated. The water tank may be detachably attached to the supply water tank 335 to replenish water or to discard water in the drain water tank 338.
In addition, instead of the supply water tank 335 and the drain water tank 338, a humidifying water pump (not shown) and a drain pump (not shown) may be provided, and hoses may be connected to the pumps, respectively, so that the humidifying water can be replenished and the water can be discharged.
Between the humidification bucket 331 and the inlet end of the adsorption area 220, a droplet separator 340 for separating water droplets from the humidified air is provided on a humidified air flow path 350. The sectional shape of the adsorbent provided to the humidification rotor 200 is formed in a honeycomb (honeycomb) shape, and if particles in a water droplet state are supplied to the adsorption region 220 through the humidification air flow path 350 in the humidification portion 330 to adhere to the adsorbent of the adsorption region 220, the shape of the adsorbent may be deformed, and thus performance may be degraded. Therefore, only the droplet separator 340 separates the droplet particles and returns the separated droplets to the humidification tub 331, and only the gas component is supplied to the adsorption region 220 through the droplet separator, thereby preventing the performance of the humidification rotor 200 from being degraded.
The humidified air flow path 350 is composed of a closed flow path so that the humidified air delivered by the second blower 310 is repeatedly circulated through the adsorption region 220, the filter 320, the humidification tub 331, and the droplet separator 340 in this order.
The humidified air flow path 350 is composed of a closed flow path, so that bacteria may proliferate inside the flow path. Therefore, the humidified air flow path 350 is made of a transparent material that can transmit ultraviolet rays, and the humidified air flow path 350 can be kept sanitary by providing an ultraviolet germicidal lamp that irradiates ultraviolet rays to the humidified air flow path 350.
The operation of the humidifier constituted as described above will be described.
When the humidifier is activated, the first blower 130, the second blower 310, and the heater 140 are turned on (on), and the humidifying rotor 200 is rotated. In this case, the humidification filter 332 immersed in the water is rotated in the humidification unit 330, or the water is sprayed to the humidification filter 332, so that the moisture is attached to the humidification filter 332. When water is sprayed to the humidification filter 332, if the amount of the sprayed water is small, the humidification filter 332 becomes dry, and scale may be accumulated on the surface of the humidification filter 332. Therefore, the amount of water sprayed to the humidification filter 332 is made larger than the amount of humidification, and the amount of spraying is periodically adjusted, thereby preventing the problem of scale accumulation.
When the second blower 310 is activated, the following cycle is repeated: the moisture adhering to the humidification filter 332 in the humidification unit 330 evaporates and flows into the humidification air flow path 350 together with the air, passes through the adsorption region 220 of the humidification rotor 200, adheres to the adsorbent in the adsorption region 220, and flows into the humidification water tank 331 of the humidification unit 330 through the filter 320.
Meanwhile, when the first blower 130 is activated, the indoor air flowing into the first indoor air flow path 151 passes through the filter 110, is once preheated in the heat recovery heat exchanger 120, and then is heated in the heater 140, and the indoor air heated while passing through the heater 140 passes through the humidification region 210 of the humidification rotor 200. In this case, since the adsorbent adsorbing the moisture from the adsorption region 220 rotates and is located in the humidification region 210, the moisture of the adsorbent is evaporated while the heated indoor air passes through the humidification region 210, and thus the humidified indoor air is formed. The indoor air passing through the humidification region 210 flows through the second indoor air flow path 152 while being cooled to a predetermined temperature by the heat recovery heat exchanger 120, and is then discharged into the room.
The humidifying operation is performed in the same manner as described above, and when the operation is stopped after the humidifying operation is completed or after the humidifying operation is performed for a predetermined time, the remaining water in the humidifying tub 331 is discharged to the drain tank 338, so that the high-concentration water can be prevented from causing scale to accumulate in the humidifying filter 332 or the driving unit for rotating the humidifying filter 332.
After the humidification operation is completed, the remaining water in the humidification tub 331 is discharged to the drain tank 338, and then the second air blower 310 is operated for a predetermined time, thereby drying the inside of the humidification tub 331 and the humidification air flow path 350. Through these processes, contamination due to residual moisture inside the humidification air flow path 350 and the humidification tub 331, which are closed flow paths, can be prevented.
< second embodiment >
A humidifier according to a second embodiment will be explained with reference to fig. 3.
The humidifier according to the second embodiment is different from the first embodiment in that the humidified air flow path 350-1 is not a closed flow path but is implemented to communicate with the outside, and the rest of the constitution is all the same.
One side end and the other side end of the humidified air flow path 350-1 communicate with the outside. Therefore, the outdoor air flows in through one side end of the humidified air flow path 350-1, and the outdoor air flowing in serves as the humidified air described in the first embodiment. The humidified air passes through the humidifying unit 330, the droplet separator 340, and the second blower 310 in this order, passes through the adsorption region 220 of the humidifying rotor 200, and is then discharged to the outside again. With this configuration, new air flows into the humidified air flow path 350-1 without generating residual moisture, thereby preventing contamination.
< Structure of moving by heating Motor >
A structure in which the indoor air is preheated by heat generated by the motor of the blower will be described with reference to fig. 4 and 5.
Referring to fig. 4, the first blower 130 is provided in the first indoor air flow path (151: 151a, 151 b). The first blower 130 is composed of a motor 131 and a blower fan 132 rotated by the motor 131. The motor 131 is provided adjacent to the first indoor air flow path 151a on the indoor air inflow side, and the indoor air flows while absorbing heat generated from the motor 131 to be preheated. The blowing fan 132 is provided adjacent to the first indoor air flow path 151b on the side where the indoor air is discharged after passing through the first blower 130, and flows the indoor air by the rotation of the blowing fan 132. Since the indoor air flowing to the first indoor air flow path 151b by the blowing fan 132 is once preheated by the motor 131 and then supplied to the heater 140, power consumption of the heater 140 can be reduced.
Fig. 5 shows a case where the air blowing part 400 is equipped with: the third blower 440 preheats the indoor air by heat generated by the motor 441 while rotating the two blower fans 442, 443 by one motor.
The air supply part 400 includes: a humidified air blowing space 410 communicating with the humidified air flow path (350: 350a, 350 b); an indoor air blowing space 430 communicating with the indoor air flow paths (150: 151a, 151 b); a partition wall 420 that blocks the humidified air supply space 410 and the indoor air supply space 430; the third blower 440 includes a motor 441 for integrally rotating a first blower fan 442 located in the indoor air blowing space 430 and a second blower fan 443 located in the humidified air blowing space 410.
The first blowing fan 442 and the second blowing fan 443 are integrally connected to a motor shaft 444 penetrating the partition wall 420, and the motor shaft 444 is connected to the motor 441, so that the first blowing fan 442 and the second blowing fan 443 are integrally rotated by one motor 441. The space for installing the blower can be reduced.
Further, since the motor 441 is provided in the indoor air blowing space 430 communicating with the indoor air flow path (150: 151a, 151b), the indoor air is preheated while passing through the motor 441 and is supplied to the heater 140, and thus, power consumption of the heater 140 can be reduced.
As described above, the present invention is not limited to the above-described embodiments, and those having a basic knowledge in the technical field to which the present invention pertains can realize modifications within the limits of the technical idea of the present invention without departing from the scope of claims, and these modified embodiments belong to the scope of the present invention.
