## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of Korean Patent Application No. 10-2014-0001244, filed on Jan. 6, 2014 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
BACKGROUND
1. Field
Embodiments of the present disclosure relate to a dehumidifier, and more particularly, to a dehumidifier with an improved structure of a water tank in order to enhance convenience in use of the water tank.
2. Description of the Related Art
In general, a dehumidifier is an apparatus for to intake humid air in the indoor space, to pass the air through a heat exchanger including a condenser through which refrigerant circulates and an evaporator to lower the humidity of the air, and then to reintroduce the dehumidified air to the indoor space, thereby lowering the humidity of the indoor space.
That is, the dehumidifier evaporates refrigerant in the liquid state in the evaporator to take away heat from the ambient air. Then, when the refrigerant is evaporated, the temperature of the evaporator is reduced so that air passing through the evaporator is cooled accordingly.
Accordingly, the temperature around the evaporator gets lower so that moisture included in the air is condensed to form dewdrops on the surface of the evaporator.
A water tank for storing condensed water formed on the surface of the evaporator may be provided inside the dehumidifier. The water tank may include a handle for conveniently moving the water tank.
However, if the handle is installed in the water tank, a storage capacity of condensed water may be reduced. Furthermore, the internal structure of the water tank becomes complicated, which makes cleaning the water tank and maintaining cleanliness of the water tank difficult. In order to overcome the problem, a handle is desired to be attached to the outside of the water tank. However, in this case, when the water tank is separated and moved from the dehumidifier, the water tank may be inclined so that condensed water spills out of the water tank.

In detail, the heat exchanger 50 may be rested on a heat exchanger resting portion 42 formed on the plate 41. On the plate 41, a plurality of fixing protrusions 43 spaced away by the length of the heat exchanger 50, protruded upward, and configured to fix the heat exchanger 50 at both edges may be formed.
Air entering the main body 10 through the air entrance 15a may exchange heat with refrigerant circulating in the heat exchanger 50. The dehumidifier 1 may include one or more heat exchangers 50. When the dehumidifier 1 includes a plurality of heat exchangers, the heat exchangers may be arranged to face each other. Also, the heat exchangers may have the same size or different sizes. The heat exchanger 50 may include a plurality of ducts 51 including internal passages communicating with each other in order to accelerate heat exchange between air entered the main body 10 through the air entrance 15a and refrigerant.
The heat exchanger 50 may function as a compressor and an evaporator, which will be described later.
On the plate 41, a water passageway 44 to guide condensed water formed by heat exchange and condensed on the heat exchanger 50 to the water tank 100 may be formed.
The frame 40 may further include a blowing fan resting portion 45 that is coupled to the upper portion of the plate 41, and a water tank resting portion 46 that is coupled to the lower portion of the plate 41. That is, the plate 41 may partition the frame 40 into the blowing fan resting portion 45 and the water tank resting portion 46.
The blowing assembly 60 may function to expel air entered the main body 10 through the air entrance 15a through the air exit 16a. The blowing assembly 60 may include a blowing fan 61, a blowing fan housing 62, and a blowing motor 63.
The blowing fan 61 may rotate such that air is sucked in the air entrance 15a and expelled through the air exit 16a. The blowing fan housing 62 may receive the blowing fan 61 and support it. The blowing motor 63 may provide rotation power to the blowing fan 61 so that the blowing fan 61 can rotate.
The blowing fan housing 62 may be coupled to the blowing fan resting portion 45 facing the first direction A to face the inner side of the first panel 11. The blowing fan 61 received in the blowing fan housing 62 may be inserted into a resting hole 65 formed in the blowing fan resting portion 45.
The blowing motor 63 may be rested on a motor resting portion 66 formed in the first direction A in the blowing fan housing 62. The blowing fan 61 received in the blowing fan housing 62 may rotate with respect to a motor shaft 64 connected to the blowing motor 63. On the blowing fan housing 62, a plurality of coupling parts 67 arranged along the motor resting portion 66 and protruded in the first direction A may be formed. The blowing motor 63 may be fixed on the motor resting portion 66 by a motor mount 68 that is coupled to the plurality of coupling units 67.
The blowing fan housing 62 may be coupled to the blowing fan resting portion 45 to form a discharge passageway 69a. The discharge passageway 69a may be formed at a location corresponding to the discharge grille 16 formed in the third panel 13. In detail, a guide duct 69 formed in the upper portion of the blowing fan housing 62 may be connected to the discharge grille 16 to form the discharge passageway 69a. The guide duct 69 may be integrated into the blowing fan housing 62. Accordingly, air entering the main body 10 through the air entrance 15a may move along the discharge passageway 69a via the heat exchanger 50, and then be expelled through the air exit 16a. 
The compressor 70 to compress refrigerant circulating in the heat exchanger 50 may be mounted on a compressor receiving portion 71 formed in the fourth panel 14. The compressor 70 may be disposed below the plate 41 so that the compressor 70 is positioned below the heat exchanger 50. Also, the compressor 70 may be disposed in the interior of the second panel 12 such that the compressor 70 faces the water tank 100 coupled to the water tank resting portion 46 with the water tank resting portion 46 in between.
The dehumidifier 1 may further include an expansion valve (not shown) to decompress and expand refrigerant passed through the heat exchanger 50.
Refrigerant may be compressed by the compressor 70. Refrigerant passed through the compressor 70 may be transferred to the heat exchanger 50 that functions as a condenser, cooled by air entered the main body 10, and condensed. Refrigerant passed through the heat exchanger 50 functioning as a condenser may be transferred to the expansion valve, and then decompressed and expanded. The decompressed, expanded refrigerant may absorb heat from the air entered the main body 10 and thus evaporate in the heat exchanger 50 functioning as an evaporator. During heat exchange between the refrigerant and the air entered the main body 10, condensed water may be formed on the heat exchanger 50, and the condensed water may move along the water passageway 44 formed on the plate 41 and be stored in the water tank 100.
The dehumidifier 1 may further include one or more control boxes 80.
The control boxes 80 may be disposed in the interior of the first panel 11. The control boxes 80 may be mounted on the blowing fan housing 62 to face the inner side of the first panel 11. Each control box 80 may include a plurality of components such as a circuit board to control overall operations of the dehumidifier 1 through manipulation of the manipulation buttons provided on the first panel 11.
The water tank 100 may be detachably attached to the water tank resting portion 46 in order to store condensed water formed during heat exchange between air entered through the air entrance 15a and refrigerant.
The water tank resting portion 46 may be coupled to the fourth panel 14. If the water tank 100 may be attached to the water tank resting portion 46, the water tank 100 may be positioned between the plate 41 and the fourth panel 14. The water tank 100 attached to the water tank resting portion 46 may be rested on a recess portion 14a formed in the fourth panel 14, wherein the shape of the recess portion 14a corresponds to the bottom shape of the water tank 100. The water tank 100 attached to the water tank resting portion 46 and rested on the recess portion 14a forms the external appearance of the dehumidifier 1 facing the first direction A, together with the first panel 11 that is coupled to the upper part of the plate 41. The water tank resting portion 46 may be exposed to the outside in the first direction A, when the water tank 100 is detached from the water tank resting portion 46.
The water tank 100 may include a storage space 110 and a handle 120.
Condensed water may be stored in the storage space 110 formed in the water tank 100. In the upper portion of the water tank 100 that faces the lower side of the plate 41 when the water tank 100 is attached to the water tank resting portion 46, an inlet opening 140 may be formed so that condensed water transferred from the heat exchanger 50 along the water passageway 44 formed on the plate 41 is collected in the storage space 110. However, the location of the inlet opening 140 is not limited to the upper portion of the water tank 100. Also, the inlet opening 140 may be in the shape of a hole or slit, however, the shape of the inlet opening 140 is also not limited to these.
The handle 120 may be coupled to the water tank 100 in order for a user to easily carry the water tank 100 detached from the water tank resting portion 46. Also, the handle 120 may be coupled to the outer part of the water tank 100.
More specifically, the handle 120 may be coupled to the outer part of the water tank 100 in such a manner to be able to slide with respect to the outer part of the water tank 100.
The handle 120 may be coupled to the outer part of the water tank 100 in such a manner to be able to rotate with respect to the outer part of the water tank 100.
Hereinafter, for convenience of description, the humidifier 1 is assumed to have a structure in which the handle 120 is coupled to the outer part of the water tank 100 in such a manner to be able to slide with respect to the outer part of the water tank 100.
The handle 120 may be inclined with respect to the outer part of the water tank 100.
The handle 120 may be coupled to one side of the water tank 100, and inclined toward the other side of the water tank 100. More specifically, the handle 120 may be coupled to a handle coupling portion 130 of the water tank 100 that faces the water tank resting portion 46 such that the handle 120 is inclined upward in the first direction A. That is, the handle 120 may be coupled to the handle coupling portion 130 of the water tank 100 in the state of being inclined toward the center of the water tank 100, such that one end of the handle 120 is located on an extension line of the center of gravity of the water tank 100. This will prevent condensed water stored in the storage space 110 from spilling out due to inclination of the water tank 100 caused by the weight of the condensed water, in the case in which the handle 120 is coupled to one side of the water tank 100.
The handle coupling portion 130 may have a curved surface which is convex in the first direction A.
On the handle coupling portion 130 of the water tank 100, one or more guides 131 extending in an up-down direction may be formed. The guides 131 may be protruded in the second direction B. The height of each guide 131 in the second direction B may change in the up-down direction. More specifically, the protrusion height of each guide 131 may be lower at the upper portion.
The handle 120 may include one or more supporting units 121 and a holding unit 122.
The supporting units 121 may slide in the up-down direction along the guides 131.
The holding unit 122 may be connected to the upper ends of the supporting units 121 so that a user can grip the holding unit 122.
The number of the supporting units 121 corresponds to the number of the guides 131. For example, if two guides 131 are formed on the handle coupling portion 130 to be spaced away from each other, the handle 120 may include two supporting units 121 that can slide in the up-down direction along the guides 131. In this case, the holding unit 122 may connect the two supporting units 121.
However, the number of the guides 131 and the supporting units 121 is not limited as long as it is one or more.
On each supporting unit 121, a stopper 123 may be protruded in the first direction A. The stopper 123 may be caught by a catch element 133 formed on the upper end of the corresponding guide 131, and prevent the supporting unit 121 from being separated from or deviating out of the guide 131 when the handle 120 slides in the up direction.
A cover 150 to receive the guides 131 therein may be attached to the handle coupling portion 130 such that the cover 150 faces the water tank resting portion 46.
A portion of the cover 150 facing the water tank resting portion 46 may have a curved surface which is convex in the first direction A, like the handle coupling portion 130.
The cover 150 may be coupled to the guides 131 to form a plurality of engaging holes 151. The supporting units 121 may pass through the engaging holes 151 to slide in the up-down direction along the guides 131.
The holding unit 122 may be caught by the upper plate of the cover 150 protruding in the second direction B to thereby prevent the supporting units 121 from being separated from or deviating out of the guides 131 when the handle 120 slides downward.
The water tank 100 may include a first unit 101 and a second unit 102 that can be separated from each other. The first unit 101 and the second unit 102 may be coupled to form an external appearance of the water tank 100, and form the storage space 110 therein. The first unit 101 wherein the inlet opening 140 is formed in the upper portion may be made of a transparent material so that a user can check the amount of condensed water stored in the storage space 110.
The second unit 102 may also be made of a transparent material.
However, materials of the first and second units 101 and 102 are not limited to transparent materials.
FIG. 10 is a perspective view of the water tank 100 of the dehumidifier 1 according to an embodiment of the present disclosure when a handle of the water tank is drawn out.
As shown in FIG. 10, when the water tank 100 is attached to the water tank resting portion 46 to form the external appearance of the dehumidifier 1 facing the first direction A together with the first panel 11, the holding unit 122 of the handle 120 may closely contact the upper plate of the cover 150.
If a user separates the water tank 100 from the water tank resting portion 46, and then grips the holding unit 122 to pull the handle 120 upward, the handle 120 may be inclined in the first direction. Accordingly, condensed water stored in the storage space 110 of the water tank 100 may be prevented from spilling out due to inclination of the water tank 100.
FIG. 11 is a view for describing air flow of a dehumidifier according to an embodiment of the present disclosure.
As shown in FIG. 11, air flow in the main body 10 proceeds as follows.
If air in the indoor space is conditioned by passing through the filter 20, and then enters the main body 10, the air exchanges heat with refrigerant circulating in the heat exchanger 50. More specifically, air entered the main body 10 may exchange, as described above, heat with refrigerant while passing through the compressor 70, the heat exchanger 50 functioning as a condenser, the expansion valve (not shown), and the heat exchanger 50 functioning as an evaporator, in this order. Thereby, moisture in the air may be formed as condensed water on the heat exchanger 50, and the condensed water may be collected in the storage space 110 of the water tank 100 via the water passageway 44 formed on the plate 41. The dehumidified air may be expelled through the air exit 16a via the discharge passageway 69a. 
As described above, according to the embodiments of the present disclosure, since the handle is located on the outer part of the water tank, a storage space for condensed water in the water tank may increase, and the internal structure of the water tank may be simplified, so that it is easy to maintain cleanliness of the water tank.
