Hereinafter, the operation of the dehumidifier according to the present invention will be described in more detail with reference to FIG. 2.

First, when the dehumidifier is operated, the control unit installed in the control box 130 operates the compressor 10, the compressor 10 compresses the refrigerant and supplies it to the condenser 20, and the condenser 20 is The gas refrigerant is condensed into a liquid refrigerant, and the refrigerant condensed in the condenser 20 is expanded by the expansion liquid 30 into the liquid refrigerant in the sprayed state and then evaporated into gas in the evaporator 40.

At this time, the refrigerant evaporated into the gas in the evaporator 40 is heat-exchanged with the indoor air introduced into the cabinet 60 to cool the indoor air, the surface of the evaporator 40 in the cooling process of the indoor air Condensed water is generated by the temperature difference to dehumidify the indoor air.

Thereafter, the refrigerant evaporated in the evaporator 40 flows to an accumulator (not shown), is separated into a gas / liquid state, and then moved to the compressor 10 again.

Next, the process of moving the air by the dehumidifier with reference to Figure 2 or 3 as follows.

The control unit applies the power to the blower fan assembly 50 to operate the blower fan assembly 50 to introduce indoor air into the cabinet 60 and then discharge it back to the room.

At this time, indoor air is introduced into the cabinet 60 through the inlet 102a formed in the side panel 102 and the holes 142a / slit 104b formed in the front frame 142. Is moved to the filter assembly 120 and filtered.

Here, the indoor air passing through the filter assembly 120 is filtered while passing through the filter 128 installed in the filter case 124, and the air passing through the filter 128 passes through the filter frame 122. Heat exchange with the evaporator 40.

The filtration air is cooled while exchanging heat with a heat radiation fin (not shown) formed in the evaporator 40. During the cooling of the filtration air, moisture in the air is condensed to form on the surface of the evaporator 40. Condensed water is collected in the drain pan (83) disposed below the evaporator (40).

In addition, the air cooled while passing through the evaporator 40 exchanges heat again with the condenser 20 installed behind the evaporator 40, and the dehumidifying air passing through the evaporator 40 and the condenser 20 exchange heat with each other. The dehumidified air is heated again.

Here, in the condenser 20, heat is dissipated during the condensation of the gas refrigerant. In the heat exchange process between the dehumidifying air and the condenser 20, the dehumidifying air is heated again to a temperature similar to the room temperature.

Thereafter, the air passing through the condenser 20 is guided to the housing 52 of the blower fan assembly 50 and sucked into the housing 52, and the air sucked into the housing 52 is transferred to the housing. It is accelerated by the centrifugal fan 54 installed therein and discharged in the circumferential direction, and the discharged air is guided upward by the housing 52.

Here, the air discharged to the upper side of the housing 52 is discharged back into the room through the discharge port 106a formed in the upper panel 106 and the discharge hole 104a formed in the rear panel 104.

Therefore, the dehumidifier according to the present invention generates air flow in all directions of the room in which the dehumidifier is installed because the dehumidifier inhales air through the front / side and discharges the air to the top / rear.

On the other hand, the controller adjusts the rotation angle of the louver 107 installed in the upper panel 106 to adjust the direction and the flow rate of the discharged air.

Thus, when the air is discharged to the upper front of the cabinet 60, the louver 107 is rotated to the rear in the closed state to form a discharge port in the front, and when to discharge the air to the upper rear, rotates forward in the closed state To form a discharge port.

Next, look at the movement of the condensate in the dehumidifier according to the present invention with reference to FIG.

First, the condensed water condensed in the evaporator 40 and collected in the drain pan 83 flows into the bucket 94 through a water collecting port 83c of the drain pan 83, and is stored in the bucket 94. The amount of condensate stored in the inside is sensed by the water level detecting unit 110 or the weight sensing unit 150, and the control unit is connected to the display device 135 of the dehumidifier according to the amount of condensate stored in the bucket 94. This is indicated.

In particular, the weight sensing unit 150 measures the weight of the condensate, calculates the height of the condensate inside the bucket 94 by an empirical formula, and then displays the height of the condensate on the display device 135 so that the user stores the condensate. When the height is known and the condensed water is full in the bucket 94, an LED (not shown) of the display device is turned on to inform the user of the drainage time of the bucket 94.

In addition, the full water detection device 110 detects the condensate inside the bucket 94 is stored above a predetermined height, and transmits it to the control unit, the control unit stops the operation of the compressor 10 was operated to condensate Is prevented from overflowing in the bucket 94.

On the other hand, although not shown, the water level detecting device 110 is to intermittently install the power applied to the compressor 10 from the control unit to directly control the power applied to the compressor 10 from the control unit when the condensed water is full. It may be configured.

Next, the process of separating the bucket by the user will be described with reference to FIG. 2 or FIG. 4.

First, the user opens the front panel assembly 140 to drain the condensate of the bucket 94, the front panel assembly 140 is rotated about the bracket 145 of the left side panel 102, the other end is Open the inside of the cabinet 60.

In addition, the user pulls the handle 95 of the bucket 94 to separate the bucket 94 from the barrier 80.

At this time, the bucket 94 is seated on the bucket guide 92, the bucket guide 92 is a structure in which the hinge (92a) of the front is connected to the barrier 80, the user is the bucket The upper end of the bucket 94 is rotated forward by the operation of pulling 94 forward.

Here, the bucket 94 is moved to a position where the user can easily lift the upper part of the bucket from the inside of the barrier 80 by the user pulling the handle 95 of the bucket 94, The lower end of the bucket 94 is moved away from the bucket guide 92 by lifting the handle 95 pivoted forward.

Thus, since the bucket 94 is separated at a time while the user grasps the handle 95, the bucket 94 has a simple separation process.

On the other hand, the assembly process of the bucket 124 is performed in the reverse order of the separation process, a detailed description thereof will be omitted.

Next, the filter replacement process in the filter assembly will be described with reference to FIG. 2.

First, the user opens the front panel assembly 140 as in the separation process of the bucket 94.

Since the front frame 142 is hinged to the right side of the cabinet 60, the front panel assembly 140 is opened while being rotated in the left and right direction about the right side of the cabinet.

Then, the filter case 124 and the filter frame 122 are separated.

Here, the upper end of the filter case 124 and the filter frame 122 is fixed by the fixing mechanism 126, the user presses the upper end of the filter case 124 hook formed on the filter case 124 127 and the fixing mechanism 126 is separated.

On the other hand, since the lower end of the filter case 124 and the filter frame 122 is fixed by the hinge 124a, when the hook 127 and the fixing mechanism 126 are separated as described above, the filter case 124 ) Rotates forward about the hinge 124a.

In addition, the user removes the filter 128 inserted in the sliding direction to the sliding guide 124b formed in the filter case 124 in the upward direction.

On the other hand, the assembly process of the filter 128 is carried out in the reverse order of separation, detailed description thereof will be omitted.

The dehumidifier according to the present invention constituted as described above is operated by the opening and closing method of the front panel assembly, the filter case connected to the heat exchanger and the filter case for mounting the filter in a sliding manner is hinged, the simple manual installation and removal of the filter There is an advantage you can only do.
