Description

DEHUMIDIFICATION-TYPE AIR CLEANER
The present invention relates to a dehumidification-type air cleaner and, more particularly, to a dehumidification-type air cleaner which is reduced in overall size but has an increased air purification effect and expels clean air by sterilizing a dehumidifying unit thereof in which a large amount of harmful microorganisms may propagate.
In general, an air cleaner draws in contaminated indoor air to filter out dust, odor particles, or the like, contained therein, to thus produce purified air. The purified air is expelled to the outside of the air cleaner, namely, to an indoor area.
Basically, an air cleaner is a device that draws in contaminated ambient air and expels clean air to the outer side thereof to purify ambient air.
To this end, the air cleaner may include an intake device for allowing ambient air to be introduced thereinto and expelling purified air, and a filter filtering out dust, odor particles, or the like, contained in the introduced air.
However, the air cleaner simply allows ambient air to be introduced thereinto, purifies it, and expels purified air, without removing moisture contained in the introduced air.
Thus, in the case that the air cleaner is driven in an environment in which a high level of humidity is present, such as during summer in certain climates, moisture contained in the air may be transmitted to a deodorization filter, or the like, and attached to a surface thereof, degrading performance thereof.
Namely, in the case that moisture is attached to the surface of the deodorization filter, moisture clings to contaminants in the air.
Thus, a degree of contamination of a filter may be increased, or air holes in the filter may be clogged, lowering intake efficiency of the filter, which leads to a shortening of a replacement cycle and a life span of the filter.
In order to solve these problems, recently, air cleaners including a dehumidifying unit to allow for simultaneous air purification and dehumidification functions have been used.
Here, in the related art air cleaner including the dehumidification function, as air, which has passed through a filter, passes through a dehumidifying unit, it is purified and moisture contained therein is removed.
In this case, however, moisture in the air may be condensed on (or congealed on) and attached to an evaporator included in the dehumidifying unit, so if the air cleaner continues to be used, various harmful microorganisms will propagate on the evaporator and air passing through such an evaporator will be introduced to an indoor area while containing various harmful microorganisms or odor particles.
In addition, in the dehumidifying unit of the related art air cleaner having a dehumidification function, the evaporator is sequentially disposed with a condenser, side by side, increasing a space in a horizontal direction within the air cleaner, which disadvantageously leads to an increase in the overall volume of the air cleaner.
Derived to solve the forgoing problems of the related art, a dehumidification-type air cleaner according to an embodiment of the present invention has an object to solve the problems as follows.
An aspect of the present invention provides a dehumidification-type air cleaner capable of filtering out harmful microorganisms or odor particles contained in the air, which has passed through a dehumidifying unit, to once again provide purified air.
Another aspect of the present invention also provides a dehumidification-type air cleaner having a relatively reduced overall volume by changing a disposition of a condenser and an evaporator therein.

Meanwhile, the dehumidification-type air cleaner 1000 according to an embodiment of the present invention will be described on the assumption that a portion in which the intake unit 500 is disposed within the housing 100 corresponds to a rear stage (or a rear portion) of the housing 100.
However, a front stage and a rear stage are used for the sake of explanation, and the dehumidification-type air cleaner 1000 according to an embodiment of the present invention is not limited thereto.
Constitutions of respective embodiments will be described in detail.
[First embodiment]
In the dehumidification-type air cleaner 1000 according to a first embodiment of the present invention, harmful microorganisms or odor particles contained in the air which has passed through the dehumidifying unit 300 are filtered out once again through a disposition of the dehumidifying unit 300 and the filter units 200 and 400, and the overall volume of the air cleaner can be relatively reduced.
With reference to FIG. 2, the dehumidifying unit 300 is disposed in a rear stage of the first filter unit 200 and removes moisture from the air which has passed through the first filter unit 200.
In general, a filter disadvantageously has performance degraded in an environment having a high level of humidity, and the dehumidification-type air cleaner 1000 according to an embodiment of the present invention complements the shortcomings of the degradation of performance of the filter by removing moisture from the air by disposing the dehumidifying unit 300 in a front stage of the second filter unit 400.
The dehumidifying unit 300 may include a compressor 330, a condenser 310, an expansion valve (or a capillary), and an evaporator 320 constituting a general refrigerating cycle.
Here, the condenser 310 and the evaporator 320 constituting the dehumidifying unit 300 may be installed in upper and lower portions in a straight line in a thickness direction.
Thus, in the dehumidification-type air cleaner 1000 according to an embodiment of the present invention, a space taken by the condenser 310 and the evaporator 320 within the air cleaner 1000 can be reduced, and thus, the overall volume of the air cleaner can be relatively reduced.
In case of the related art dehumidifier, a low air current force intake fan is used, having relatively low heat exchange efficiency, so a large capacity condenser 310 and evaporator 320 are disposed in a line in a direction in which air flows.
Thus, the overall volume of the related art dehumidifier is relatively increased.
However, the dehumidification-type air cleaner 1000 according to an embodiment of the present invention employs the relatively high air current force intake fan in comparison to the related art dehumidifier, thus obtaining effectiveness substantially equal to that of the related art dehumidifier although the capacity of the condenser 310 and the evaporator 320 is reduced.
Thus, by disposing the condenser 310 and the evaporator 320 at upper and lower portions, respectively, the effect of maintaining dehumidification performance while reducing the overall volume of the dehumidification-type air cleaner 1000 can be obtained.
Meanwhile, a plurality of fins having various shapes may be provided in the condenser 310 and the evaporator 320 to increase thermal efficiency.
Also, since the dehumidification-type air cleaner 1000 according to an embodiment of the present invention employs a high air current force intake fan, a rotational speed thereof can be reduced, and accordingly, noise that may be generated from the intake unit 500 can be reduced.
Meanwhile, the condenser 310 and the evaporator 320 may be disposed in upper and lower portions in a thickness direction, irrespective of disposition order.
Namely, the condenser 310 may be disposed in the upper portion while the evaporator 320 is disposed in the lower portion, or alternatively, the condenser 310 may be disposed in the lower portion while the evaporator 320 may be disposed in the upper portion.
Meanwhile, as shown in FIG. 3, the condenser 310 and the evaporator 320 constituting the dehumidifying unit 300 may be disposed in a length direction, namely, in a line in a direction in which air flows.
With reference to FIG. 2, the second filter unit 400 is disposed in a rear stage of the dehumidifying unit 300 to filter out foreign objects which have not been filtered in the first filter unit 200. Also, the second filter unit 400 may filter out various harmful microorganisms or odor particles that may be generated in the dehumidifying unit 300.
Namely, moisture present in the air congeals on and is attached to the surface of the evaporator 320. Thus, in the case that the dehumidification-type air cleaner 1000 continues to be used with the lapse of time, various harmful microorganisms may propagate, and also, particulates such as odor particles, or the like, may also adhere thereto as well.
In this state, if air introduced to the housing 100 is introduced to an indoor area through the evaporator 320, various harmful microorganisms or particulates including odor particles existing in the evaporator 320 are also introduced together.
However, since the dehumidification-type air cleaner 1000 according to an embodiment of the present invention includes the second filter unit 400 disposed in the rear stage of the dehumidifying unit 300, various harmful microorganisms or particulates including odor particles existing in the dehumidifying unit 300, as well as foreign objects, which have not been filtered out in the first filter unit 200, can be filtered out.
Accordingly, in comparison to the related art dehumidification-type air cleaner in which a filter unit is disposed only in the front stage of the dehumidifying unit 300, more clean purified air can be introduced to an indoor area.
Here, the second filter unit 400 may include at least one of a deodorization filter 410 for removing odor particles and a high efficiency particulate arresting air (HEPA) filter 420 for removing particulates from the introduced air.
It is obvious that, alternatively, the second filter unit 400 may be configured to include various other filters that are able to remove particulates.
Meanwhile, the second filter unit 400 may be formed in a detachable manner so as to be replaced. Here, the second filter unit 400 may be replaced in various manners. For example, as shown in FIGS. 4 and 5, the second filter unit 400 may be replaced through a lateral side in a sliding manner.
Alternatively, the second filter unit 400 may also be replaced through an upper or lower surface in a sliding manner.
With reference to FIG. 2 or 6, the housing 100 includes the inlet 110, and the first filter unit 200, the dehumidifying unit 300, the second filter unit 400, and the intake unit 500 are disposed within the housing 100.
Various switches including a switch for operating power of the dehumidification-type air cleaner 1000 according to an embodiment of the present invention, a switch for adjusting an air current force, and the like, may be installed on the housing 100.
Meanwhile, a handle unit 600 may be formed on an upper portion of the housing 100 for the convenience of a movement.
Here, the handle unit 600 may include a grasp portion 610 taken by the user’s hand and a pair of insertion portions 620 connected to the grasp portion 610 and formed to be inserted into the housing 100 (or extending from or retracted into the housing 100).
As shown in FIG. 6 or 7, the grasp portion 610 may be formed as a longitudinal member that can be grasped by the hand. Here, a lateral cross-sectional of the grasp portion 610 may have a quadrangular or circular shape.
A pair of insertion portions 620 are connected to both end portions of the grasp portion 610 and coupled to recesses formed in the housing 100 so as to be inserted into the housing 100.
After the dehumidification-type air cleaner 1000 according to an embodiment of the present invention is disposed in a certain location, the handle unit 600 may be inserted into the housing 100 to reduce the volume occupying a space.
Meanwhile, in the case that the dehumidification-type air cleaner 1000 according to an embodiment of the present invention is intended to be moved to a different location, the handle unit 600 may be protruded and the user may take the handle unit 600 to easily move the dehumidification-type air cleaner 1000 according to an embodiment of the present invention.
Here, the insertion portions 620 may be formed in a push latch button type that can be inserted and protruded by pressing.
Here, the insertion portions 620 may have a spring to allow the handle unit 600 to be protruded.
Also, a stopper is provided at one side of the insertion portions 620 to prevent the entirety of the insertion portions 620 from being protruded from the housing 100.
Meanwhile, the push latch button type may include any known techniques for inserting and protruding by pressing.
Here, the insertion portions 620 may be provided as a pair and coupled to both end portions of the grasp portion 610.
Also, as shown in FIG. 7, the insertion portions 620 include a projection 622 that can be inserted into and fixed in the housing 100, and the housing 100 may include a projection stopper 624 into which the projection 622 is coupled.
Here, a plurality of projections 622 having an arrow shape are formed on the insertion portion 620 and formed to be branched (or fork). The projection 622 may be made of a material having elasticity.
The projection stopper 624 may be formed to have sections whose sizes are varied (please see FIG. 7).
Namely, a recess is formed in an upper portion of the housing 100, and the projection stopper 624 having sections that vary in size may be installed in the recess.
Here, the projection 622 is fixedly caught in the projection stopper 624 as follows: When the projection 622 passes through the portions of the projection stopper 624 having the varied sections, the fork portions of the projection 622 are open to both sides due to an elastic action and the projection 622 formed to have an arrow shape is caught in the projection stopper 624.
Accordingly, the handle unit 600 is inserted in the housing 100 and maintained.
Meanwhile, in the case that a strong force is applied in an upward direction with the handle unit 600 held in a user’s hand, the projection 622 caught in the projection stopper 624 may be released out and the handle unit 600 can be protruded.
