Description

Technical field

[0001] The present invention relates to a dehumidification and humidification device, a dehumidifier-air purifier, a humidifier-air purifier, and a method for their operation.

The level of technology

[0002] In general, the dehumidification and humidification device performs the function of dehumidification, the function of humidification and the function of air cleaning.

[0003] The dehumidification and humidification device can be implemented using different methods of dehumidification and humidification. As a drying method, a method using a heat exchanger is widely used, in which the drying efficiency is high, and a natural evaporation method using a moisturizing filter is widely used as a wetting method.

[0004] A dehumidification and humidification device that implements a method using a heat exchanger and a natural evaporation method comprises a heat exchanger and a humidifying filter in a single flow channel, preferably formed in the housing.

[0005] However, since the area of the heat exchanger is usually larger than the area of the moisturizing filter, an empty space is formed above the moisturizing filter, i.e. dead space in which air purification is not carried out.

[0006] The dehumidification and humidification device in accordance with the prior art has the disadvantage that the degree of humidification is lower than the size of the air flow, because when the air is humidified, there is air released outside without passing through the humidifying filter, due to dead space.

[0007] Thus, there is a need for a technology to increase the degree of humidification, so that when the air is humidified, as much air as possible sucked into the housing can pass through a humidifying filter.

[0008] At the same time, the air purifier dehumidifier may include a heat exchanger that performs the function of drying, and an air filter that performs the function of air purification, while the intake air can be cleaned by passing through the air filter and can be dried by passing through a heat exchanger.

[0009] In addition, in order for a dehumidifier-air purifier, if necessary, to perform the function of air purification and the function of dehumidification using a single blower fan, the air filter and heat exchanger are usually placed in the same flow channel.

[0010] If the air filter has a small area and a large thickness, then the negative pressure in the flowing air increases. If the heat exchanger has a large area and a small thickness, then the time of heat exchange with air is reduced, thereby reducing the drying characteristics. Therefore, the area of the inlet section of the air filter is usually made relatively larger than the area of the inlet section of the heat exchanger.

[0011] In the dehumidifier-air purifier in accordance with the prior art, due to the above-described difference between the areas of the inlet section of the air filter and the heat exchanger, the flow channel is significantly narrowed to the heat exchanger, therefore the amount of air intake decreases. As a result, the dehumidifier-air purifier has the disadvantage that the air purification characteristics are reduced.

[0012] To solve this problem, if the flow channel to the heat exchanger is enlarged so that it is located at a distance from the edge of the heat exchanger when the drainage function is performed, the amount of air bypassing the heat exchanger without passing through it increases, therefore there is a lack of that the drying characteristics are reduced.

[0013] In addition, to eliminate the above disadvantage, if you manufacture a heat exchanger with larger sizes, then there is a disadvantage that significantly increases production costs.

[0014] At the same time, the humidifier-air purifier performs the function of humidification, introducing moisture into the air, in addition to the function of air purification, in order to purify the air by removing the impurities it contains.

[0015] The air purifier humidifier can be implemented using different humidification methods. In detail, the natural evaporation method is widely used, in which moisture is introduced into the air through the use of a moisturizing filter, the lower part of which is immersed in a water tank.

[0016] Such a humidifier-air purifier that implements a natural evaporation method may include an air filter and a humidifier filter in the internal flow channel. Generally, since the area of the air filter is larger than the area of the humidifying filter, an empty space forms in the upper part of the humidifying filter, i.e. dead space in which air purification is not carried out.

[0017] In this case, when the air is subjected to humidification, due to the specified dead space, there is air which, without passing through the humidifying filter, is released into the room, therefore there is a disadvantage that the degree of humidification is lower than the air flow.

The preferred implementation

[0044] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that those skilled in the art will be able to easily implement the present invention. In the following description of the present invention, a detailed description of known functions and elements included in this document will be omitted so as not to obscure the understanding of the present invention. In addition, in all the drawings for parts that perform the same function, the same reference positions are used.

[0045] In addition, in the description, an element is called "connected" with another element not only when the elements are "directly connected", but also when they are "indirectly connected" with each other. In addition, some of the details “included” means that other details are not excluded and may be additionally included other details not specifically indicated otherwise.

[0046] First, with reference to FIGS. 1-4, a drying and wetting device according to an exemplary embodiment will be described.

[0047] As shown in FIGS. 1-4, a dehumidification and humidification device 100 in accordance with an exemplary embodiment may include a housing 110, a pressure fan 120, a condenser 130, a heat exchanger 140, a water tank 150, a moisturizing filter 160, an air filter 170 , the first flow channel P1, the second flow channel P2 and the adjustable part 180 of the flow channel.

[0048] The housing 110 forms the appearance of the dehumidification and humidification device 100 in accordance with an exemplary embodiment, and may include an air intake portion 112 that allows external air to be drawn into the housing 110, and an air discharge portion 114 that allows the air inside the housing 110 to be vented to the outside.

[0049] The injection fan 120 is installed in the housing 110 and is capable of creating air flow in order to suck the outside air into the housing 110 through the air intake portion 112 and then release it again through the air outlet portion 114.

[0050] In an embodiment, the injection fan 120 may be formed from a centrifugal blower installed at the rear end of the humidifying filter 160, which will be described below, based on the direction of air movement, but this embodiment is not limited to such an arrangement.

[0051] The condenser 130 is installed in the housing 110 and may contain a refrigerant condensed in the heat exchanger 140, which will be described below. Condenser 130 may form a cooling cycle for dehumidifying air using heat exchanger 140.

[0052] In an embodiment, the condenser 130 is installed at the front end of the heat exchanger 140, but this embodiment is not limited to such an arrangement.

[0053] The heat exchanger 140 is installed in the housing 110 and is able to dry the air through heat exchange with the air.

[0054] The heat exchanger 140 may be formed from an evaporator to transfer moisture into the air as a result of cooling the air by evaporating the refrigerant therein by receiving condensed refrigerant from the condenser 130, but this embodiment is not limited to this design.

[0055] In an embodiment, the heat exchanger 140 may be located at the rear end of the condenser 130 and may be located across the first flow channel P1 and the second flow channel P2, which will be described below.

[0056] Due to the above construction, the heat exchanger 140 is able to dry the air passing through the first flow channel P1 and the second flow channel P2 when the air is dried.

[0057] The water tank 150 is installed in the housing 110 and can store water for humidification. The water tank 150 may provide the water used for moistening to a wet filter 160, which will be described below.

[0058] The humidifying filter 160 is installed in the housing 110 and is capable of humidifying the air by introducing water into the air passing through it.

[0059] In an embodiment, the humidifying filter 160 may be formed from a submersible-type natural evaporation filter in which a portion of the lower end is immersed in water stored in the water tank 160, but this embodiment is not limited to this design. Alternatively, a moisturizing filter may be formed from a drum filter.

[0060] The humidifying filter 160 is installed in the water tank 150 and may be located at the rear end of the heat exchanger 140 in the second flow channel P2, which will be described below.

[0061] The air filter 170 is installed in the housing 110 and is able to clean the air sucked into the housing 110. In an embodiment, the air filter 170 may be installed in the front end of the condenser 130, but this embodiment is not limited to such an arrangement.

[0062] In an embodiment of the present invention, the air filter 170 is not particularly limited and may be formed from a plurality of filters with different functions.

[0063] The first flow path P1 is a part of the inner space of the housing 110 and can be designed to allow air to pass through the heat exchanger 140 and the discharge fan 120.

[0064] In other words, the first flow path P1 is a portion of the space in which air passes through the condenser 130 and the heat exchanger and then flows directly into the discharge fan 120.

[0065] The second flow channel P2 is part of the inner space of the housing 110 and can be designed to allow air to pass through the heat exchanger 140, the humidifying filter 160, and the blower fan 120.

[0066] In other words, the second flow channel P2 is a part of the space in which air passes through the condenser 130 and the heat exchanger 140, passes through the humidifying filter 160, and then enters the discharge fan 120.

[0067] As shown in FIGS. 1-3, in an embodiment, the first flow channel P1 and the second flow channel P2 may be arranged parallel to each other in the housing 110.

[0068] In other words, the first flow channel P1 and the second flow channel P2 are principally located so that the area in which the humidifying filter 160 is located in the flow channel is separated from the area in which the humidifying filter is absent in it, in the space in which air moves due to the injection fan 120. In addition, the first flow channel P1 and the second flow channel P2 do not constitute a pipe construction in which the first flow channel and the second flow channel are separated from each other so that the spirit does not pass.

[0069] The adjustable portion 180 of the flow passage is provided in the housing 110 and is capable of selectively opening and closing at least a portion of the first flow passage P1.

[0070] To implement the above operation, in an embodiment, the adjustable part 180 of the flow channel may include a baffle 182 and a drive motor 186, as shown in FIG. 4.

[0071] the Guide wall 182 is a plate element provided in the first flow channel P1 for directing air entering the first flow channel P1.

[0072] In an embodiment, the baffle 182 may be configured to rotate between the heat exchanger 140 and the discharge fan 120 in the first flow path P1.

[0073] The guide bulkhead 182 may be located downward toward the humidifying filter 160 when the guideline turns downward to close at least part of the first flow channel P1, as shown in FIG. 1, and may be located upward inclined the side opposite the moisturizing filter 160, i.e. to the upper end of the first flow channel P1, when the guide wall rotates upward to open the first flow channel P1, as shown in FIG. 2.

[0074] the Guide wall 182 can be combined with the support section 118, in which the rotating axis 184 is located in the frame 116 inside the housing 110 for rotation.

[0075] At the same time, in one embodiment, the guide wall 182 may be configured to allow the end portion to bend in the direction opposite to the direction of rotation of the guide wall 182, as shown in FIG. In this case, the baffle 182 can rotate without hindrance, elastically bending, even if the baffle collides with the heat exchanger casing 140 or the element inside the casing 110, as shown in FIG. 3, when the baffle wall rotates.

[0076] As an example, the baffle 182 may be made of a material with sufficient strength to withstand the pressure of the air flow sucked into the first flow channel P1, and may be in the form in which material with sufficient elasticity that is bent is attached to end portion, but this embodiment is not limited to such an implementation. The entire guide bulkhead 182 may be made of the same material and may have a small thickness to allow the end portion to bend.

[0077] The driving motor 186 may be connected to the rotating axis 184 of the baffle 182 in order to allow the baffle 182 to rotate.

[0078] In an embodiment, the driving motor 186 may be provided in the form of a stepping motor for adjusting the angle of rotation.

[0079] The driving motor 186 may be controlled by a control unit (not shown) for controlling the humidification function and the dehumidification function of the dehumidification and humidification device 100 in accordance with an exemplary embodiment.

[0080] In an embodiment, said control unit may control the driving motor 186 so as to allow the baffle 182 to be inclined downward when the air is humidified, and can control the driving motor 186 so as to allow the baffle 182 to be positioned under the inclination up when air is being drained.

[0081] The adjustable part 180 of the flow channel, having the configuration described above, can cover at least part of the first flow channel P1 when the baffle 182 is inclined downward, as shown in FIG. 1, while the humidifying filter has the function of moistening .

[0082] In this case, the adjustable part 180 of the flow channel may direct air entering the first flow channel P1 and passing through the heat exchanger 140 to the moistening filter 160.

[0083] In this case, the maximum amount of air sucked into the housing 110 can pass through the humidifying filter 160.

[0084] Alternatively, while the heat exchanger 140 performs the drying function, the adjustable part 180 of the flow channel may open the first flow channel P1 when the baffle 182 is tilted upwards, as shown in FIG.

[0085] In this case, the air entering the first flow channel P1 may pass through the upper part of the heat exchanger 140 and then may enter the discharge fan 120, and the air entering the second flow channel P2 may pass through the lower part of the heat exchanger and then fall into the discharge fan 120.

[0086] In this case, when the heat exchanger 140 performs the function of drying, the humidifying filter 160 may be removed from the second flow channel P2, or the water may be removed from the water tank 150.

[0087] Below, with reference to FIGS. 5 and 6, a dewatering and wetting device 100 ′ according to another embodiment will be described.

[0088] As shown in FIGS. 5 and 6, unlike the dehumidification and humidification device 100 in accordance with the exemplary embodiment described above with reference to FIGS. 1-4, the dehumidification and dehumidification device 100 'in accordance with another embodiment may additionally include a sealing partition 190.

[0089] The sealing wall 190 may be connected between the end of the guide wall 182 and the outer end of the first flow channel P1 and is configured to collapse and unfold under external force.

[0090] In another embodiment, the sealing wall 190 may be made of a material through which air can pass.

[0091] The sealing wall 190 may close the first flow path P1 at the end of the guide wall 182 when the guide wall 182 is inclined downward, as shown in FIG. 5, when the air is moistened.

[0092] In this case, the air entering the first flow channel P1 does not enter the dead space formed above the guide wall 182, and can be operatively guided towards the second flow channel P2 by means of the sealing partition 190.

[0093] Thus, the dehumidification and humidification device 100 'in accordance with another embodiment simplifies the characteristics of the air flow when the air is humidified, as compared with the dehumidification and humidification device 100 in accordance with the exemplary embodiment described above with reference to FIG. 1-4, thereby having the advantage of a relative improvement in air flow.

[0094] At the same time, when the air is humidified, in the case when the guide wall 192 is inclined upward, the sealing wall 190 collapses, as shown in FIG. 6, and is thus withdrawn from the first flow channel P1.

[0095] The dehumidification and humidification devices 100 and 100 'according to exemplary embodiments allow the maximum amount of intake air to pass through the humidification filter 160 by switching the flow channel when the air is humidified, even if the heat exchanger 140 and the humidification filter 160, having different areas, are located in the same flow channel, thereby having the advantage of increasing the degree of moisture.

[0096] Below with reference to Fig.7-9 will be described dehumidifier-air purifier in accordance with an exemplary embodiment of the implementation.

[0097] As shown in FIGS. 7-9, the air dryer-air cleaner 200 in accordance with an exemplary embodiment may include a housing 210, a pressure fan 220, a humidifying unit 230, an air filter 240, a condenser 250, a heat exchanger 260, an adjustable flow channel 270 and a device 280 that opens and closes the flow channel.

[0098] The housing 210 may form the appearance of the air dryer-air cleaner 200 in accordance with an exemplary embodiment, and may include an air intake portion 212 for drawing in outside air into the housing 210 and an air outlet portion 214 for exhausting air from the housing 210 to the outside.

[0099] Furthermore, in an embodiment, a frame section 216 may be provided in the case 210 for fixing the air filter 240 and the heat exchanger 260 in the case 210 by supporting the edge of the air filter 240 and the heat exchanger 260, as will be described below.

[00100] The frame portion 216 may form a flow passage to allow air sucked into the housing 210 through the air intake portion 212 to pass through the air filter 240 and heat exchanger 260.

[00101] The injection fan 220 may be installed in the housing 210, and air flow may occur allowing air sucked into the air intake portion 212 to pass through the air filter 240, heat exchanger 260 and the humidifying unit 230 and then pass to the air outlet 214.

[00102] In an embodiment, the injection fan 220 may be located behind the heat exchanger 260 and the moisturizing unit 230 based on the direction of air movement (the direction of the rear end in which air comes out based on the direction of air movement), but this embodiment is not limited to such an arrangement.

[00103] The moisturizing unit 230 is provided in the housing 210 and is capable of humidifying the air passing through it.

[00104] The wetting method and the configuration of the moisturizing unit 230 are not particularly limited.

[00105] As an example, a dehumidifier-humidifier-air purifier in accordance with an exemplary embodiment may use a humidification filter used for the humidification method through natural evaporation, and may include a water tank 232 to supply water to the humidification filter, which is shown in FIG. .7 and 8 as a moisturizing unit 230, but this embodiment is not limited to this design.

[00106] At the same time, in an embodiment, the moisturizing unit 230 may be located between the heat exchanger 260 and the blower fan 220, which will be described below, but this embodiment is not limited to this arrangement.

[00107] The air filter 240 is installed in the housing 210 and is capable of cleaning the air sucked into the housing 120.

[00108] In an embodiment, the air filter 240 may be located directly behind the air intake portion 212 in the housing 210, as shown in FIGS. 7 and 8.

[00109] As described above, due to the fact that the air filter 240 is located directly behind the air intake section 212, the air passing through the inside of the housing 210 is cleaned before it enters the condenser 250, the heat exchanger 260 and the humidifying unit 230, which will are described below, thereby having the advantage of preventing the elements behind the air filter 240 from being contaminated.

[00110] In an embodiment, the air filter 240 is not particularly limited and may be formed from a filter system in which a plurality of filters having different functions and shapes are combined with each other.

[00111] The condenser 250 is installed in the housing 210 and is capable of condensing the refrigerant and thus can supply the condensed refrigerant to the heat exchanger 260, which will be described below.

[00112] The capacitor 250 is not particularly limited and may be provided in the form of different types of capacitor 250 commonly used and known in the art.

[00113] In addition, the condenser 250 may be located between the air filter 240 and the heat exchanger 260, as shown in Figures 7 and 8, but this embodiment is not limited to this arrangement, and may be placed in the housing 210 in different positions.

[00114] The heat exchanger 260 may be installed behind the air filter 240 based on the direction of air movement in the housing 210.

[00115] Heat exchanger 260 is able to remove moisture by condensing moisture in the air by absorbing heat from the air participating in the heat exchange process, due to evaporation of the refrigerant.

[00116] In an embodiment, the heat exchanger 260 may be configured to have a smaller area compared to the area of the air filter 240, as shown in FIGS. 7 and 8.

[00117] In other words, the heat exchanger 260 may be sized to cover part of the air filter 240 when the heat exchanger overlaps with the air filter 240.

[00118] The adjustable flow passage 270 may form a passage around the heat exchanger 260.

[00119] In an embodiment, the adjustable flow channel 270 may correspond to the space between the frame portion 216 and the edge of the heat exchanger 260, as shown in FIGS. 7 and 8.

[00120] The adjustable flow channel 270 can be opened and closed by the device 280, which opens and closes the flow channel, which will be described later.

[00121] In an embodiment, in the region of the edge of the condenser 250 and the heat exchanger 260, a support rib 265 may additionally be provided to secure the condenser 250 and the heat exchanger 260 to the housing 210 and to separate the flow passage 270.

[00122] The device 280, opening and closing the flow channel, is provided for opening and closing the adjustable flow channel 270.

[00123] The device 280, opening and closing the flow channel, may be configured to open the adjustable flow channel 270 when the air dryer-air cleaner 200 in accordance with the exemplary embodiment performs air cleaning and close the adjustable flow channel 270 when the air is exposed draining.

[00124] Here, when the device 280, opening and closing the flow channel, closes the adjustable flow channel 270, the device 280, opening and closing the flow channel, can direct the air passing through the air filter 240 and moving towards the adjustable flow channel 270, the direction of the heat exchanger 260.

[00125] In order to carry out the above operation, as an example, the device 280 opening and closing the flow channel may include a guide plate 282, a drive unit 284, and a portion 286 of elastic material.

[00126] the Guide plate 282 is placed in the frame section 216 and can be made to rotate in the direction of the heat exchanger 260.

[00127] The guide plate 282 has a shape adapted to close the adjustable flow channel 270, and can direct the air moving in the direction of the adjustable flow channel 270 towards the heat exchanger 260 when the adjustable flow channel 270 is closed.

[00128] In addition, the drive unit 284 is located in the frame portion 216 and is able to rotate the guide plate 282.

[00129] The drive unit 284 may perform the function of opening and closing the adjustable flow channel 270 through the guide plate 282, depending on the user's control command, and may be connected to a control unit (not shown) to perform the function of opening and closing the adjustable flow channel 270 via the guide plate 282, in order to provide an automatic closure of the adjustable flow channel 270, when the dryer-air purifier in accordance with an exemplary embodiment is performed It doesn’t have a drainage function, and automatically opens the adjustable flow channel 270 when the air is cleaned.

[00130] In an embodiment, the drive unit 284 is formed of a stepper motor capable of adjusting the angle of rotation of the guide plate 282, and can be configured to control the opening area of the adjustable flow channel 270.

[00131] In addition, an elastic material portion 286 is provided at the end of the guide plate 282 and may be in tight contact with the heat exchanger body 260 when the said body is flexed, as shown in FIG. 8, when the adjustable flow channel 270 is closed.

[00132] The elastic material portion 286 is in tight contact with the support rib 265 so as not to form a gap between the guide plate 282 and the support rib 265, thereby preventing air from moving along the adjustable flow channel 270 when the adjustable flow channel 270 is closed.

[00133] In addition, the elastic material portion 286 has a cushioning effect in the connecting portion between the guide plate 282 and the support rib 265, so as to prevent vibrations from the air dryer-cleaner 200 in accordance with the exemplary embodiment from being transmitted to the guide plate 282 is activated and thus prevents noise due to collisions between elements in the process.

[00134] As an example, a portion 286 of elastic material may be made of extruded polyvinyl chloride (PVC), but this embodiment is not limited to this material.

[00135] The air dryer-air cleaner 200 in accordance with the above-described exemplary embodiment has the advantages of increasing the drying efficiency by preventing air from moving around the heat exchanger 260 when the air is being dried and increasing the cleaning efficiency of the air by increasing the area of the air intake area when the air is cleaned .

[00136] In addition, the air dryer-air cleaner 200 in accordance with an exemplary embodiment has the advantage of reducing product cost by optimizing the size of heat exchanger 260.

[00137] Figure 10 is a block diagram of a humidifier-air purifier in accordance with an exemplary embodiment.

[00138] With reference to figure 10, the humidifier-air cleaner 300 in accordance with an exemplary embodiment may include a cleaning unit 310, a moisturizing unit 320, a discharge unit 330, an adjustable part 340 of the flow channel, a sensor unit 350 and a control unit 360.

[00139] The cleaning unit 310 is provided for filtering contamination contained in the air moving, for example, in the air humidifier 300, and can remove the pollution so that air pollution moving in the air humidifier 300 is absorbed, or in a similar way.

[00140] The cleaning unit 310 may include one or more air filters. For example, the cleaning unit 310 may include various types of filters, such as a coarse filter, a functional filter, a high efficiency particulate air filter (HEPA filter), a deodorizing filter, or the like. A coarse filter is provided for remove relatively large particles of dust, hair, pet hair, or the like; a functional filter is provided to remove bacteria, pollen, mites, spores, microorganisms, or the like; a HEPA filter is provided to remove various particles, such as fine dust Either home molds or the like, and a deodorizing filter is provided to remove various household odors and harmful gases or the like.

[00141] The humidifier unit 320 is provided for introducing water into the air moving in the humidifier-air cleaner 300. For example, the moisturizing unit 320 may introduce water into the air by the method of natural evaporation. In this case, the moisturizing unit 320 may include a water tank 321 and a moisturizing filter 322, which will be described below with reference to FIGS. 11 and 12.

[00142] In the air flow channel in the humidifier-air cleaner 300, the above-described cleaning unit 310 may be located at the front end of the moisturizing unit 320, but the positions of the cleaning unit 310 and the moisturizing unit 320 are not limited to such positions.

[00143] In addition, in the air flow channel in the humidifier-air cleaner 300, the area of the cleaning unit 310 may be larger than the area of the moisturizing unit 120. In this case, the air entering the humidifier-air cleaner 300 can pass only through the cleaning unit 310 and can pass through the cleaning unit 310 and through the moisturizing unit 320. In other words, the flow channel for air in the humidifier-air cleaner 300 can be divided into a first flow channel (P1 shown in FIG. 11) in which air passes only through cleansing a second unit 310, and a second flow channel (P2, shown in FIG. 11), in which air passes through the cleaning unit 310 and through the moisturizing unit 320.

[00144] The discharge unit 330 is provided to create an air flow to allow outside air to penetrate the humidifier-air cleaner 300, and may include a pressure fan and an electric motor for driving this fan. In this case, the blower fan is made rotatable by means of an electric motor and can thus generate air flow. The operation of the electric motor can be controlled by the control unit 360, which will be described below.

[00145] The adjustable part 340 of the flow channel is provided for selectively opening and closing a part of the air flow channel in the air humidifier 300, depending on the control signal from the control unit 360. For example, the adjustable portion 340 of the flow passage may allow the first flow passage described above to open and close. Specific configurations and functions of the adjustable part 340 of the flow channel will be described below with reference to FIGS. 11-13.

[00146] The sensor unit 350 is formed from different sensors for obtaining information about air quality or environmental information in the space in which the humidifier / air purifier 300 is installed.

[00147] For example, the sensor unit 350 may include a humidity sensor for measuring the humidity of the air in the space in which the humidifier-air cleaner 300 is installed.

[00148] The sensor unit 350 may transmit a measurement signal to the control unit 360 to allow the control unit 360 to control the operation of the humidifier-air cleaner 300, as will be described below.

[00149] The control unit 360 is provided for controlling the operation of the humidifier-air purifier 300, may be provided in the form of a processor, for example, a central processing unit (CPU), a graphics processing unit (GPU), a microprocessor, a specialized integrated circuit ( application specific integrated circuit (ASIC), a user programmable gate array (field programmable gate array - FPGA) or the like, and may include memory for storing different types of data.

[00150] For example, the control unit 360 may control the operation of the humidifier-air purifier 300 based on user input or a signal transmitted from the sensor unit 350, and may control the operation of the adjustable part 340 of the flow channel when the humidifier-air purifier 300 performs the function moisturizing.

[00151] In detail, the control unit 360 may close part of the flow channel of the humidifier-air purifier 300 by controlling the adjustable part 340 of the flow channel, as will be described later with reference to FIG. 11, when the humidifier-air cleaner 300 starts to perform the humidification function. Thus, a larger amount of air passes through the humidifier unit 320, so that the efficiency of humidification can be increased.

[00152] In addition, the control unit 360 allows the sensor unit 350 to periodically measure the current humidity, while the humidifier-air purifier 300 performs the humidification function, and can allow the flow channel of the humidifier-air purifier 300 to open by controlling the adjustable part 340 of the flow channel, as will be described below with reference to FIG. 12, when the measured current humidity is within a predetermined desired humidity range (eg, from 40% to 60%). Thus, the amount of air passing through the humidifying unit 320 is reduced, so that a continuous increase in humidity is prevented and the required level of humidity is maintained.

[00153] In addition, the control unit 360 may terminate the humidification function of the humidifier-air purifier 300 when the measured current humidity exceeds a predetermined humidity level (for example, equal to 70%).

[00154] Fig.11 is a side view in section, showing the case in which part of the flow channel of the humidifier-air purifier in accordance with an exemplary embodiment of the implementation is closed, and Fig.12 is a side view in section, showing the case in which flow the humidifier-air purifier duct in accordance with an exemplary embodiment is open.

[00155] With reference to FIGS. 11 and 12, the housing 301 forms the appearance of the humidifier / air purifier 300, and the housing 301 may include an air intake opening 302, allowing external air to penetrate into the interior of the housing 301, and an air outlet 303, allowing air to escape from the housing 301 outward.

[00156] An air filter 311 forming the cleaning unit is installed in the case 301 to clean the air sucked into the case 301 through the air intake port 302. The air filter 311 may be provided at the front end of the humidifying filter 322, which will be described later based on the direction in which air moves in the flow channel of the humidifier-air cleaner 300, but the position of the air filter 311 is not limited to such a position.

[00157] In addition, the air filter 311 may be located across the first flow channel P1 and the second flow channel P2, which will be described below, and thus the air filter 311 can clean the air passing through the first flow channel P1 and the second flow channel P2.

[00158] The water tank 321 and the moisturizing filter 322 forming the wetting unit can be installed in the housing 301.

[00159] With this, the water tank 321 contains water for humidification and provides water for the wet filter 322, which will be described below.

[00160] The moisturizing filter 322 may introduce water into the air passing through it. For example, the humidifying filter 322 may be provided in the form of a submersible-type natural evaporation filter, in which a portion of the lower end of the humidifying filter is immersed in the water contained in the water tank 321, but this embodiment is not limited to this design. For example, the moisturizing filter 322 may be provided in the form of a drum filter.

[00161] In addition, the humidifying filter 322 may be located at the rear end of the air filter 311 based on the direction in which air moves in the flow channel of the humidifier-air purifier 300, but the position of the humidifying filter 322 is not limited to this location.

[00162] In addition, the humidifying filter 322 is located in the second flow channel P2, which will be described below, and introduces water into the air passing through the second flow channel P2.

[00163] The injection fan 311 forming the discharge unit is installed in the housings 301 and can create an air flow in order to suck the outside air into the casing 301 through the air intake 302, and then release it again through the air outlet 303.

[00164] The injection fan 311 may be provided at the rear end of the humidifying filter 322, which will be described below, based on the direction in which air moves in the flow channel of the air humidifier / air purifier 300, but the position of the delivery fan 311 is not limited to this location.

[00165] The first flow path P1 is a part of the internal space of the housing 301 in which air moves into the discharge fan 331 after the air passes only through the air filter 311.

[00166] In addition, the second flow channel P2 is another part of the inner space of the housing 301, in addition to the first flow channel P1, in which air moves to the injection fan 311 after the air passes through the air filter 311 and the humidifying filter 322.

[00167] As shown in FIGS. 11 and 12, the first flow channel P1 and the second flow channel P2 can be formed in parallel next to each other in the internal flow channel of the housing 301. In other words, the first flow channel P1 and the second flow channel P2 are in principle made so that the area in which the humidifying filter 322 is located is separated from the area in which the humidifying filter is missing in the flow channel, in which air moves due to the injection fan 331. In addition, the first flow channel P1 and the second flow channel P2 is not physically separated by a structure that does not allow air to move between them.

[00168] The adjustable part 340 of the flow channel is installed in the housing 301 and may allow the first flow channel P1 to open and close.

[00169] The adjustable part 340 of the flow channel may include a baffle 341 and a driving motor 342, as shown in FIG.

[00170] With this, the baffle 341 is a plate element provided in the first flow channel P1 to direct air entering the first flow channel P1, and is rotatable between the air filter 311 and the discharge fan 311 in the first flow channel P1. For example, a baffle 341 can be combined with a pivotal support portion in which its rotating axis is provided in a frame within the housing 301.

[00171] Guide baffle 341 may be inclined downward toward humidifying filter 322 when the first flow path P1 is closed when the guide bent is turned downward, as shown in FIG. 11, and may be positioned sloped upward to the side opposite the moistening filter 322, i.e., to the upper end of the first flow channel P1, when the first flow channel P1 is open, when the guide wall rotates upward, as shown in FIG. 12.

[00172] A driving motor 342 is provided to provide rotation of a baffle 341 connected to a rotating axis of the baffle 341, and may be provided, for example, in the form of a stepping motor capable of adjusting the angle of rotation. The operation of the driving motor 342 may be controlled by a control unit.

[00173] Fig.14 is a block diagram of the sequence of operations of the method works

s humidifier-air purifier in accordance with another embodiment.

[00174] With reference to FIG. 14, when the humidifying function of the humidifier-air purifier is turned on (S310), a part of the flow channel of the humidifier-air purifier, i.e. an adjustable flow channel, is closed (S320), and thus more air can pass through moisturizing filter.

[00175] Then, while the humidifier-air purifier performs the function of humidification, the current humidity is periodically measured (S330). If the measured current humidity is within a predetermined desired humidity range (for example, from 40% to 60%) (S340), open the adjustable flow channel (S350), and re-start the above step S330.

[00176] At the same time, if the measured current humidity exceeds a predetermined humidity (eg, equal to 70%) (S360), the humidifying function of the humidifier-air purifier is stopped (S370).

[00177] The operation method of the humidifier-air purifier, described above with reference to FIG. 14, may be implemented by hardware, such as a processor attached to the humidifier-air purifier, or the like.

[00178] Although the present invention is specifically shown and described with reference to exemplary embodiments thereof, it is not limited to them. It will be obvious to those skilled in the art that various changes and modifications thereof may be made within the spirit and scope of the present invention, and therefore it should be understood that such changes and modifications are within the scope of the appended claims.
