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

What is claimed is:

1. 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 first area overlapping the wireless charging module in a vertical direction,
a second area that does not overlap the wireless charging module in a vertical direction, and
a charging groove formed in a bottom surface of the first area 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 and defined by forming a first thickness of the first area thinner than a second thickness of the second area.

2. The air purifier according to claim 1 , wherein the charging groove is recessed upwardly from the bottom surface of the first area facing the upper surface of the wireless charging module.

3. The air purifier according to claim 1 , wherein the upper panel further includes a rib extending downward from the charging groove and configured to press against the wireless charging module.

4. The air purifier according to claim 3 , 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.

5. The air purifier according to claim 1 , 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.

6. The air purifier according to claim 5 , 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 plate.

7. The air purifier according to claim 1 , further comprising: a water tub positioned under the electric plate and positioned in a lower portion of the cabinet; a humidifying filter assembly positioned under the electric plate 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.

8. The air purifier according to claim 7 , wherein the wireless charging module is positioned in front of the guide plate.

9. The air purifier according to claim 1 , wherein the electric plate includes an electric base on which the wireless charging module is disposed, the electric base being positioned below the upper panel, and
wherein the upper panel forms a flat top surface of the cabinet, and
wherein the wireless charging module is configured to wirelessly charge an electronic device disposed on the upper panel.

10. The air purifier according to claim 9 , wherein the electric plate further includes a base supporter extending upward along an edge of the electric base, the base supporter contacting the upper panel.

11. The air purifier according to claim 1 , wherein the upper panel includes an area adapted for placement of an electronic device to be wirelessly charged by the wireless charging module.

12. The air purifier according to claim 1 , wherein the upper panel includes a sheet marking a charging position of an electronic device during wireless charging.

13. The air purifier according to claim 1 , further comprising:
a wired charging module installed in the electric plate; and
a USB port provided on one side of the cabinet and electrically connected to the wired charging module.

14. The air purifier according to claim 1 , further comprising a Wi-Fi printed circuit board (PCB) installed in the electric plate.

15. The air purifier according to claim 1 , wherein the wireless charging module includes a coil assembly positioned vertically below the charging groove.

16. The air purifier according to claim 3 , wherein the heat dissipation space is defined as a space between the bottom surface of the upper panel and the upper surface of the wireless charging module separated by the rib.

17. The air purifier according to claim 1 , wherein an upper portion of the wireless charging module is received in the charging groove.

18. The air purifier according to claim 6 , wherein the electric base further includes a support rib protruding upward from the electric base and configured to support a lower portion of the other electric devices at a vertically spaced distance from the electric base.

19. The air purifier according to claim 18 , wherein a protruding height of the wireless module boss is equal to a protruding height of the wireless module bracket and higher than a protruding height of the support rib.

20. The air purifier according to claim 1 , wherein the upper panel is made of wood material.
