Abstract

A dehumidifier is provided that may include a bucket; a drain pan including a drain passage configured to guide condensed water dropped from an evaporator to the bucket; a pump; a pump water inlet line connected to the pump, the pump water inlet line being configured to guide the condensed water in the bucket to the pump; a pump water outlet line connected to the pump, the pump water outlet line being provided with an outlet installed in the drain passage or disposed above the bucket, and an outer tube connected to the pump water outlet line in the drain passage or above the bucket.

First claim

What is claimed is:

1. A dehumidifier, comprising:
a bucket;
a drain pan having a drain passage configured to guide condensed water dropped from an evaporator to the bucket;
a pump;
a pump water inlet line connected to the pump, the pump water inlet line being configured to guide the condensed water in the bucket to the pump;
a pump water outlet line connected to the pump, the pump water outlet line being provided with an outlet installed in the drain passage or disposed above the bucket; and
an outer tube connected to the pump water outlet line in the drain passage or above the bucket, wherein a drain hose and the outer tube are selectively connected to the dehumidifier, wherein the drain pan comprises a drain conduit provided above the bucket, wherein the outlet is disposed inside the drain conduit, wherein the outer tube is connected to the outlet within the drain conduit, wherein the drain hose is connected with the drain conduit, wherein the outer tube is longer than the drain hose, and wherein the outer tube has an inner diameter less than an inner diameter of the drain hose.

2. The dehumidifier according to claim 1 , further comprising:
a casing defining an outer appearance, wherein an outer through-hole through which the outer tube passes is defined in the casing, and the drain conduit faces the outer through-hole.

3. The dehumidifier according to claim 1 , wherein the pump water outlet line comprises:
a water outlet fitting at least a portion of which is accommodated in the drain passage and to which the outer tube is connected; and
a water outlet tube connected to the water outlet fitting.

4. The dehumidifier according to claim 3 , wherein the pump water outlet line further comprises:
a pump tube connected to an outlet of the pump; and
a connecting fitting connected to each of the pump tube and the water outlet tube.

5. The dehumidifier according to claim 4 , wherein a hole is defined in one side of the drain pan, and the connecting fitting passes through the hole.

6. The dehumidifier according to claim 4 , wherein a pump tube connection portion of the connecting fitting to which the pump tube is connected is disposed outside of the drain pan, and a water outlet tube connection portion to which the water outlet tube is connected protrudes from the drain passage.

7. The dehumidifier according to claim 1 , wherein a fixing portion configured to fix the pump water outlet line to the drain pan is disposed in the drain passage.

8. The dehumidifier according to claim 1 , further comprising:
a barrier configured to partition a space within the dehumidifier into a bucket space in which the bucket is accommodated and a machine room in which the pump is accommodated; and
a waterproof wall that protrudes from the barrier to the machine room to cover an upper side of the pump.

9. The dehumidifier according to claim 1 , further comprising:
a barrier configured to partition a space within the dehumidifier into a bucket space in which the bucket is accommodated and a machine room in which the pump is accommodated; and
a pair of bucket covers bent from the barrier, wherein a bucket cover through-hole through which the outer tube passes is defined in one of the pair of bucket covers.

10. The dehumidifier according to claim 1 , further comprising:
a float configured to be elevated along a float guide disposed on the bucket;
a water level sensor configured to sense a full water level according to a height of the float; and
a controller configured to drive the pump when the full water level is sensed by the water level sensor and stop the pump when a predetermined time has elapsed after the pump is driven.

11. A dehumidifier, comprising:
a bucket;
a drain pan comprising a drain passage configured to guide condensed water dropped from an evaporator to the bucket;
a pump;
a pump water inlet line connected to the pump, the pump water inlet line being configured to guide the condensed water in the bucket to the pump; and
a pump water outlet line which is connected to the pump and to which the condensed water pumped by the pump is guided, wherein the drain pan comprises a drain conduit disposed above the bucket, and the pump water outlet line comprises an outlet accommodated in the drain conduit, wherein the condensed water of the pump water outlet line is drained through an outer tube connected to the outlet, or the condensed water of the drain conduit is drained through a drain hose connected to the drain conduit, wherein the outer tube is connected to the outlet within the drain conduit, wherein the drain hose and the outer tube are selectively connected to the dehumidifier, wherein the outer tube is longer than the drain hose, and wherein the outer tube has an inner diameter less than an inner diameter of the drain hose.

12. The dehumidifier according to claim 11 , wherein the water outlet fitting has a size less than a size of the drain conduit, and a whole or portion of the water outlet fitting is accommodated in the drain conduit.

13. The dehumidifier according to claim 11 , wherein an outlet of the water outlet fitting is disposed within the drain conduit.

14. The dehumidifier according to claim 11 , wherein an outlet of the water outlet fitting is disposed above the bucket.

15. The dehumidifier according to claim 11 , wherein a fixing portion configured to fix the water outlet fitting to the drain pan is disposed on the drain passage.

16. The dehumidifier according to claim 11 , wherein the pump water outlet line further comprises:
a water outlet tube connected to the water outlet fitting;
a pump tube connected to an outlet of the pump; and
a connecting fitting connected to each of the pump tube and the water outlet tube to pass through the drain pan.

17. The dehumidifier according to claim 11 , wherein further comprising:
a float configured to be elevated along a float guide disposed on the bucket;
a water level sensor configured to sense a full water level according to a height of the float; and
a controller configured to drive the pump when the full water level is sensed by the water level sensor and stop the pump when a predetermined time elapsed after the pump is driven.

18. A dehumidifier, comprising:
a bucket;
a drain pan configured to guide condensed water dropped from an evaporator to the bucket, the drain pan including a drain body, a water collection body, the drain body being inclined toward the water collection body, and a drain conduit;
a pump;
