Abstract

A dehumidifier may be provided that includes a water tank, a tank drawer, a frame, a main guide and a sub guide. The main guide on first and sides of the frame to guide the tank drawer when being moved inward and when being moved outward. The sub guide on the first and second sides of the frame to accommodate a rotation protrusion that protrudes from each of first and second side surfaces of the tank drawer.

First claim

What is claimed is:

1 . A dehumidifier comprising:
a main body in which a heat exchange module is provided; a water tank under the heat exchange module to collect condensed water from the heat exchange module; a tank drawer to accommodate the water tank, the tank drawer to be slidably provided at the main body; a frame to support the heat exchange module, the frame to partition a first space to accommodate the tank drawer from a second space to provide a compressor; a main guide on first and second surfaces of the frame to guide the tank drawer when the tank drawer is moved inward and when the tank drawer is moved outward; and a sub guide on the first and second sides of the frame to accommodate a rotation protrusion that protrudes from each of first and second surfaces of the tank drawer, the sub guide to guide slidable movement and rotation of the rotation protrusion at the tank drawer.

2 . The dehumidifier according to claim 1 , wherein the main guide includes a rack gear is provided in a direction in which the tank drawer is moved outward, and the dehumidifier further comprises:
a pinion gear, at the tank drawer, to be provided at the rack gear and to move along the main guide.

3 . The dehumidifier according to claim 2 , further comprising a driving motor to rotate the pinion gear.

4 . The dehumidifier according to claim 1 , wherein the main guide includes:
a horizontal part extending in a direction corresponding to inward movement of the tank drawer and outward movement of the tank drawer; and a rotation part extending from the horizontal part, the rotation part to guide rotation of the tank drawer.

5 . The dehumidifier according to claim 1 , wherein a guide member to protrude from each of the first and second surfaces of the tank drawer, and the main guide to include a guide hole to allow the guide member to be inserted therein, and to thereby guide movement of the guide member.

6 . The dehumidifier according to claim 1 , wherein the tank drawer includes a tilted part to allow the tank drawer to tilt such that the tank drawer is moved outward by a self-weight.

7 . The dehumidifier according to claim 1 , further comprising:
a main body support extending downward to prevent the dehumidifier from falling down when the tank drawer is moved outward; and a base plate to define a bottom of the dehumidifier.

8 . The dehumidifier according to claim 1 , wherein the tank drawer includes a rotation shaft at a rear of the tank drawer.

9 . The dehumidifier according to claim 1 , further comprising a locker and a latch to selectively connect with each other to maintain a closed state of the tank drawer, the locker provided at one of the tank drawer and the frame, and the latch provided at the other one of the tank drawer and the frame.

10 . A dehumidifier comprising:
a main body in which a heat exchange module is provided; a water tank under the heat exchange module to collect condensed water from the heat exchange module; a tank drawer to accommodate the water tank, the tank drawer to be slidably provided at the main body; a frame to support the heat exchange module, the frame to partition a first space to accommodate the tank drawer from a second space to provide a compressor; a drawer frame to rotatably couple to a rotation shaft at each of first and second surfaces of the tank drawer such that the tank drawer is rotatably supported; and a guide rail to couple the frame to the drawer frame, the guide rail to extend in a plurality of stages such that the tank drawer is moved inward and the tank drawer is moved outward, wherein when the tank drawer is moved outward, the tank drawer to rotate about the rotation shaft, and to expose a top surface of the water tank.

11 . The dehumidifier according to claim 10 , wherein the frame includes a rack gear on each of first and second surfaces of the frame, and
a pinion gear, at the guide rail, to be provided at the rack gear and to move along the rack gear.

12 . The dehumidifier according to claim 11 , wherein the guide rail includes:
a fixed rail to attach to the frame; and a movable rail to move along the fixed rail, the movable rail to couple to the drawer frame, wherein the pinion gear is to be rotatably provided at the movable rail.

13 . The dehumidifier according to claim 10 , wherein the tank drawer includes a guide protrusion to protrude from a surface of the tank drawer, and
the drawer frame includes a tilting guide hole to receive the guide protrusion when the tank drawer rotates.

14 . The dehumidifier according to claim 10 , wherein the tank drawer includes a tilted part to allow the tank drawer to tilt such that the tank drawer is moved outward by a self-weight.

15 . The dehumidifier according to claim 10 , further comprising:
a main body support extending downward to prevent the dehumidifier from falling down when the tank drawer is moved outward; and a base plate to define a bottom of the dehumidifier.

16 . The dehumidifier according to claim 10 , wherein the tank drawer includes the rotation shaft at a rear of the tank drawer.

17 . The dehumidifier according to claim 10 , further comprising a locker and a latch to selectively connect with each other to maintain a closed state of the tank drawer, the locker provided at one of the tank drawer and the frame, and the latch provided at the other one of the tank drawer and the frame.

18 . A dehumidifier comprising:
a body; a water tank to collect water from a heat exchange device provided at the body; a tank drawer to accommodate the water tank, the tank drawer to be slidably provided; a frame to support the heat exchange device; a first guide on a first side of the frame to guide the tank drawer; a second guide on a second side of the frame to guide the tank drawer; a first sub guide on the first side of the frame to accommodate a first rotation protrusion that protrudes from a first side of the tank drawer; and a second sub guide on the second side of the frame to accommodate a second rotation protrusion that protrudes from a second side of the tank drawer.

19 . The dehumidifier according to claim 18 , wherein the first guide includes a first rack gear, and the second main guide includes a second rack gear, and a first pinion gear to couple to the first rack gear and to move along the first main guide.

20 . The dehumidifier according to claim 18 , wherein the guide includes:
a horizontal part extending in a direction corresponding to inward movement of the tank drawer and outward movement of the tank drawer; and a rotation part extending from the horizontal part, the rotation part to guide rotation of the tank drawer.
