On the other hand, referring to FIGS. 16 and 17A, when the user hits the display module 510 in the process of opening and closing the door assembly 200, the display module 510 can be smoothly moved backward. At this time, spring 518d is compressed and a restoring force is accumulated accordingly. The damper 478 is smoothly moved rearward along the damper guide 479 without resistance.

On the other hand, as shown in FIG. 17B, when the user's hand is removed from display module 510, display module 510 can be moved forward due to the restoring force accumulated in spring 518d. Spring 518d can be tensioned. The damper gear 478c is slowly moved forward along the damper guide 479 due to the resistance of the viscous fluid filled in the damper 478. As a result, the speed at which display module 510 moves forward is reduced.

Therefore, in the process of closing the door assembly 200, the user's hand is prevented from being caught between the display module 510 and the door assembly 200, and the display module 510 is prevented from hitting the user's hand strongly in the process of returning. Therefore, stability is improved.

As mentioned above, the wireless charging module 600 may be located under the first quadrant 105h of the top panel 105. That is, the seat installed in the first quadrant 105h of the upper panel 105 (see S in FIG. 2) may be positioned above the wireless charging module 600.

Wired charging module 560 may be positioned in front of and adjacent to wireless charging module 600.

A wired module bracket 565 is provided below the wired charging module 560 to support the wired charging module 560, and a wired module chip 566 is provided above the wired charging module 560 to push the wired charging module 560 downward. It is being The wired module bracket 565 protrudes upward from the electrical base 470, and both sides of the wired module chip 566 are bent downward and coupled to the wired module bracket 565.

Wireless charging module 600 may have a short hexahedral shape. A first module side 603 having a wireless module coupler 603a is formed on one side of the wireless charging module 600. The first module side 603 is recessed on the right side of the wireless charging module 600. Since the wireless module coupler 603a is provided on the first module side portion 603, the wireless module coupler 603a does not protrude from the right side of the wireless charging module 600.

Electrical base 470 includes a wireless module boss 568 coupled to wireless module coupler 603a. The wireless module boss 568 can protrude upward from the electrical base 470 and can be fastened to the wireless module coupler 603a with a screw S.

A second module side portion 604 having a fitting portion 604a is formed on the other side of the wireless charging module 600. The second module side 604 is recessed on the left side of the wireless charging module 600. Since the second module side portion 604 is provided with the fitting portion 604a, the fitting portion 604a does not protrude beyond the left side of the wireless charging module 600. For example, the mating portion 604a may be formed to protrude from two vertical surfaces of the second module side 604.

The electric base 470 includes a wireless module bracket 567 having a groove 567a into which the fitting part 604a is inserted. The wireless module bracket 567 protrudes upward from the electrical base 470, and the grooves 567a may be formed as recesses on both sides of the top of the wireless module bracket 567.

The wireless charging module 600 may be installed on the electric base 470 such that the fitting part 604a is inserted into the groove 567a and the wireless module coupler 603a is fastened to the wireless module boss 568. The heights of wireless module boss 568 and wireless module bracket 567 protruding from electrical base 470 may be equal to each other.

The height of the wireless module boss 568 and wireless module bracket 567 protruding from the electrical base 470 may be greater than the protruding height of the support rib 475e. Therefore, the installation height of the wireless charging module 600 may be greater than the installation heights of the other PCBs 520, 530, and 540. For example, the top surface of the wireless charging module 600 is in contact with the bottom surface of the top panel 105, while the top surfaces of the other PCBs 520, 530, 540 may be spaced downwardly from the bottom surface of the top panel 105.

Because the wireless charging module 600 is positioned relatively upward, the distance between the wireless charging module 600 and the mobile device M held on the top panel 105 may be formed to be small. Therefore, wireless charging efficiency can be improved.

A charging groove 105c recessed upward is formed in the lower surface 105f of the upper panel 105 at a position corresponding to the wireless charging module 600.

The position of the charging groove 105c is formed on the upper side of the wireless charging module 600. For example, charging groove 105c may have an area greater than or equal to the area of the top surface of wireless charging module 600.

The charging groove 105c may form a heat radiation space 105d for dissipating heat of the wireless charging module 600.

Referring to FIG. 23, the portion of the top panel 105 in which the charging groove 105c is formed may have a relatively small thickness (W-H1) in the vertical direction. Therefore, the distance between mobile device M and wireless charging module 600 may be relatively shortened to enhance wireless charging efficiency.

The distance between the centers of the mobile device M and the wireless charging module 600 may preferably be 10 mm or less. If this distance exceeds 10 mm, the wireless charging efficiency of the mobile device M may deteriorate significantly.

Additionally, the mobile device M may be equipped with a separate mobile case, which may increase its thickness. Therefore, considering the mobile device M equipped with a mobile case, the thickness of the upper panel 105 to which the wireless charging module 600 is supported is preferably formed to a minimum thickness. The criteria for the minimum thickness will be discussed later.

For example, the thickness W of the top panel 105 may be set to 15 mm. The thickness W-H1 of the upper panel 105 in which the charging groove 105c is formed may be set to 4 mm. The thickness (WH2) of the upper panel 105 on which pressure ribs 105b (described later) are formed may be set to 5 mm. Therefore, the distance between the wireless charging module 600 and the mobile device M may have a value of a minimum of 5 mm and a maximum of 10 mm. Therefore, it is possible to prevent a phenomenon in which wireless charging efficiency decreases.

As mentioned above, it may be advantageous to form the charging groove 105c as deep as possible from the lower surface 105f of the top panel 105 to increase wireless charging efficiency. That is, the charging groove 105c can be formed by being recessed as much as possible from the lower surface 105f of the upper panel.

However, the top panel 105 may be made of wood. The degree of thermal deformation, breaking strength, durability, lifespan, etc. of wood can vary depending on its thickness. Therefore, the top panel 105 can be set to a minimum thickness that satisfies minimum criteria such as degree of thermal deformation, breaking strength, and durability.

In one example, the minimum thickness may be determined to be a value of 25% to 30% of the total thickness W. That is, when the total thickness W of the upper panel 105 is 15 mm, the minimum thickness of the charging groove 105c is preferably 4 mm.

As a result, the top panel 105 in which the charging groove 105c is formed can be formed to a thickness that satisfies the above-mentioned minimum criteria and maximizes the distance according to wireless charging efficiency.

The top panel 105 may be formed with a pressure rib 105b that contacts the top surface of the wireless charging module 600 and supports the wireless charging module 600.

The pressure rib 105b may be formed to protrude downward from the charging groove 105c. For example, the pressure rib 105b may extend downward by a predetermined length from the lower surface 105f of the upper panel 105 in which the charging groove 105c is formed. The predetermined length may be set to 1 mm.

The predetermined length is proportional to the size of a heat radiation space 105d, which will be described later.

The pressure rib 105b may extend so as to cross the horizontal direction and the front-back direction. For example, the pressure rib 105b may protrude in a "+" shape.

That is, the pressure rib 105 can form a heat radiation space 105d. For example, the charging groove 105c may be configured by a pressure rib 105b and a heat radiation space 105d, which is a space formed by the pressure rib 105b.

Therefore, the pressure ribs 105b can effectively pressurize the wireless charging module 600 and fix the wireless charging module 600.

On the other hand, the charging groove 105c may form a heat dissipation space 105d that can dissipate heat generated by the operation of the wireless charging module 600.

The heat radiation space 105d may be defined as a space between the wireless charging module 600 and the lower surface 105f of the upper panel separated by the pressure rib 105b.

The heat radiation space 105d can prevent the upper panel 105 from being deformed or damaged due to heat generated by the wireless charging module 600 and the mobile device M.

FIG. 29 is a diagram illustrating a state in which fluid flows into the lower side of the upper panel according to an embodiment of the present invention, and FIG. 30 is a diagram illustrating an internal drainage flow path in an air purifier according to an embodiment of the present invention. It is.

FIG. 29 shows a state in which the user drops the cup C placed on the top panel 105 of the air purifier 10 and the fluid flows to the underside of the top panel 105. In particular, fluid may flow through the display groove 108 to the electrical unit 450 side. If the fluid flows into the electrical unit 450 and acts on the electrical components, there is a possibility that the air purifier will malfunction. Therefore, a fluid evacuation structure is required.

Referring to FIG. 30, the electric base 470 may be formed to be inclined downwardly toward the rear side by a set angle A°. Specifically, the vertical height H1 of the front support 481 is larger than the vertical height H2 of the rear support 485. The side support 483 is formed such that its vertical length gradually increases from the front end to the rear end.

In other words, electrical base 470 may be configured such that the front end of electrical base 470 is positioned higher than the rear end of electrical base 470.

Electrical base 470 may be arranged to slope downwardly toward the rear, and the height of the top of base support 480 may be the same. That is, the highest heights of the front support 481, the side supports 483, and the rear support 485 are equal to each other. Therefore, the top panel 105 can be horizontally and stably placed on the electrical board 460.

The fluid that has entered the front part of the electrical unit 450 falls toward the first top cover 518a or the second top cover 519a of the display cover 517 and flows downward along the first and second steps 518e, 518f. , flows into the cover channel 518g, and can be discharged to the outside.

A portion of the fluid then flows downward along the concave surface of the second depression 519e. The fluid flowing downward falls onto the top surface of electrical base 470.

The fluid present on the top surface of the electrical base 470 moves rearward along the top surface of the electrical base 470 that slopes downwardly toward the rear side and flows through the first drain port 488a or the second drain port 488c to the electrical base. 470 may leak out. A portion of the fluid can then be drained through the wire passage hole 483a.

Water discharged from the electric base 470 flows downward from the side of the main body frame 110 and falls along the drainage channel 111c. The discharged water may then finally be collected at the base 101 of the air purifier 10.

According to this configuration, even if water is injected into the air cleaner 10, the water that has flowed into the air cleaner 10 can be prevented from penetrating into the electrical components, and the introduced water can be directed backwards. Water can be effectively drained to the outside of the electrical unit while allowing natural movement to the outside of the electrical unit.
