Abstract

An air purifier includes a display mounted between a front panel of a cabinet of the air purifier and an upper panel of the cabinet. The front panel includes a door which is configured and supported to be drawn in to the cabinet toward the display or drawn out from the cabinet away from the display. A display module including the display is disposed below the upper panel.

First claim

1 . (canceled)

2 . An air purifier comprising:
a cabinet, the cabinet including an upper panel configured to form a flat top surface of the cabinet; an electric plate configured to partition an inner space of the cabinet into an electric component space formed at an upper portion of the inner space of the cabinet and an air conditioned space formed at a lower portion of the inner space of the cabinet; an air filter and an air blowing fan disposed in the air conditioned space; and a wireless charging module disposed in the electric component space; wherein the electric plate includes an electric base on which the wireless charging module is disposed and positioned below the upper panel, and wherein the wireless charging module is configured to wirelessly charge an electronic device disposed on the upper panel.

3 . The air purifier according to claim 2 , wherein the lower portion of the inner space of the cabinet below the electric base defines a flow path for air blown through the air filter by the air blowing fan.

4 . The air purifier according to claim 2 , wherein the upper panel includes an area adapted for the placement of the electronic device to be wirelessly charged by the wireless charging module.

5 . The air purifier according to claim 2 , wherein the upper panel includes a sheet marking a charging position of the electronic device during wireless charging.

6 . The air purifier according to claim 2 , wherein the electric plate further includes a base support member extending upward along an edge of the electric base and contacting the upper surface panel.

7 . The air purifier according to claim 2 , wherein a discharge portion in communication with the air conditioned space is defined through one side of the upper panel.

8 . The air purifier according to claim 2 , further comprising:
a wired charging module disposed in the electric component space; and a USB port provided on one side of the cabinet and electrically connected to the wired charging module.

9 . The air purifier according to claim 8 , wherein the electronic device disposed on the upper panel is configured to be selectively charged by at least one of the wired charging module or the wireless charging module.

10 . The air purifier according to claim 2 , further comprising:
a Wi-Fi PCB disposed in the electric component space.

11 . An air purifier comprising:
a cabinet including an upper panel; an electric plate disposed inside the cabinet and positioned below the upper panel; an air blowing fan positioned under the electric plate; an air filter positioned under the electric plate and configured to purify air sucked into the air filter by the air blowing fan; and a wireless charging module supported by the electric plate, wherein the upper panel includes a charging groove formed in a bottom surface of the upper panel and spaced apart from an upper surface of the wireless charging module, and wherein a heat dissipation space is formed between the upper surface of the wireless charging module and the charging groove.

12 . The air purifier according to claim 11 , wherein the charging groove is positioned vertically above the wireless charging module.

13 . The air purifier according to claim 11 , wherein the upper panel further includes a rib extending downward from the charging groove and configured to press against the wireless charging module.

14 . The air purifier according to claim 13 , wherein the rib includes portions that extend orthogonally to each other and intersect with each other, and
the heat dissipation space is defined as a space between the intersecting portions of the rib.

15 . The air purifier according to claim 11 , wherein the electric plate includes:
an electric base with a surface configured for supporting the wireless charging module; and a wireless module boss and a wireless module bracket protruding upward from the electric base and configured to support the wireless charging module at a vertically spaced distance from the electric base.

16 . The air purifier according to claim 15 , wherein the wireless module bracket protrudes upward from the electric base so that the wireless charging module is positioned closer to the upper panel than other electric devices installed in the electric component space.

17 . The air purifier according to claim 11 , further comprising:
a water tub positioned under the electric base and positioned in a lower portion of the cabinet; a humidifying filter assembly positioned under the electric base and configured to absorb water stored in the water tub; a housing cover configured to allow air passing through the humidifying filter assembly to flow to a discharge portion formed on the upper panel, and configured to accommodate the air blowing fan; and a guide plate positioned on an upper end of the housing cover and shielding a partial area of the discharge portion.

18 . The air purifier according to claim 17 , wherein the wireless charging module is positioned in front of the guide plate.
