Description

An air purifier comprising a pop-up discharging part capable of controlling discharge direction}

The present invention relates to an air cleaner including a pop-up discharge unit capable of adjusting the wind direction.

The air purifier includes an intake unit for sucking outside air, a filter unit for purifying intaken air, a fan for providing power for sucking outside air and discharging the purified air, and a discharge unit for discharging the purified air. Here, the intake portion is generally located on the side and the discharge portion is located on the upper surface.

As the discharge portion is located on the upper surface, the purified air is discharged above the air cleaner. When the purified air is discharged upward, the purified air in the space (eg, living room, room) in which the air cleaner is located increases and then moves to another position to have a large trajectory. Accordingly, the air in the space is purified as a whole by convection from the space far from the air purifier. That is, it starts to purify from the air in the space farther from the air purifier, and the air in the space adjacent to the air purifier is rather purified last.

In order to purify the air adjacent to the air cleaner more efficiently, there is an air cleaner in which the discharge portion is located on the side rather than the upper surface. In this case, the above-mentioned problem is solved by directly purifying the air to the space adjacent to the air purifier, but on the contrary, the entire area where the air purifier is located is not quickly cleaned. The disadvantage is that air can be directly discharged, which may cause safety problems.

In this connection, Korean Patent No. 10-1572850 B1 discloses an air cleaner having a variable discharge unit that can be changed to a first position and a second position. In the first position mainly used, the discharge cover is spaced apart from the upper side of the discharge unit provided on the upper surface of the air cleaner. As a result, the air passing through the discharge unit is discharged upward but rises slightly obliquely. Instead of the discharge cover completely closing the upper part of the discharge unit in the second position for the concentrated cleaning, the purified air is concentrated discharged through a separate discharge unit located at the side.

In the above technique, the air purifier aims to purify both the space far from the air purifier and the space adjacent to the air purifier in order to discharge the purified air at the first position obliquely upwards. It takes more time. In addition, in the second position, the purified air is directly discharged to the adjacent space, but there is a concern that safety problems caused by high wind pressure air are discharged to a person located nearby and a problem that the user's hand may be caught in the discharge portion.

Description of Air Purifier

The air purifier according to the present invention includes a casing 100 forming an outer surface, an intake unit 110 provided on the side surface of the casing 100 to suck outside air, and two discharge parts.

As illustrated in FIGS. 1 and 2, the two discharge parts include an upper discharge part 120 positioned on a portion of the upper surface of the casing 100, and a pop-up discharge portion 200 positioned on another portion of the upper surface.

The pop-up discharge part 200 can be raised. 1 illustrates a state in which the pop-up discharge unit 200 does not rise, and FIG. 2 illustrates a state in which the pop-up discharge unit 200 is completely raised. Although not shown, adjustment to half or other elevations is also possible.

The degree of rise of the pop-up discharge unit 200 may be controlled to provide various information. For example, the degree of rise of the pop-up discharge unit 200 may be automatically controlled in accordance with the RPM of the fan provided in the fan assembly 130. That is, when the RPM of the fan is high so that the most purified air is discharged, the pop-up discharge unit 200 may be fully raised as shown in FIG. 2, and the RPM of the fan is about half so that the purified air is discharged about halfway. In this case, the pop-up discharge unit 200 may be raised to about half. In this case, the user has an advantage of knowing at a glance how much the air purifier discharges the purified air from a distance. As another example, the rising degree of the pop-up discharge unit 200 may be manually controlled. The user may adjust the degree of ascending step by step according to the control of a separate button provided in the operation unit 201, and in particular, the degree of elevation may be adjusted according to various methods such as the time of pressing the button, the number of times of pressing, and the method of pressing.

The upper discharge grill 121 is positioned on the upper surface of the upper discharge unit 120. Accordingly, the air discharged from the upper discharge part 120 is discharged upwards to purify the air from a distant space. On the contrary, the pop-up discharge part 200 discharges air to the side through the pop-up discharge grill 255 located on the side. Therefore, the pop-up discharge unit 200 purifies the air from the close space.

Since the upper discharge unit 120 and the pop-up discharge unit 200 discharge the air in different directions, and the space for purifying the air is different, it is possible to implement a variety of modes by combining them. For example, a first mode in which only the upper discharge unit 120 discharges air, a second mode in which only the pop-up discharge unit 200 discharges air, and the upper discharge unit 120 and the pop-up discharge unit 200 together supply air. The discharge may be controlled in any one of the third modes. The first mode is preferable to purify the entire space or to purify the air from a distant space, and the second mode is preferable to purify the air from a space close to the air cleaner rather than the entire air.

An operation unit 201 having a plurality of buttons that can be operated by a user may be positioned on an upper surface of the pop-up discharge unit 200. Details of the pop-up discharge unit 200 will be described later.

A configuration inside the casing 100 will be described with reference to FIGS. 3 to 5. 3 to 5 are views for omitting a part of the casing 100 for explanation.

The filter assembly 115 is located inside the casing 100. Outside air taken in through the intake unit 110 is purified while passing through the filter assembly 115. The number and type of filters that may be included in the filter assembly 115 are not limited.

The pop-up discharge part inserting part 126 is a space opened up and down, and the pop-up discharge part 200 is inserted therein so as to be liftable.

The flow path guide 150 is positioned on the bottom surface of the discharge part housing 125.

One upper portion of the flow guide 150 forms a passage with the pop-up discharge portion inserting portion 126, the other upper portion forms a passage with the upper discharge portion 120, and the lower portion forms a passage with the fan assembly 131. do. That is, the flow path guide 150 has a Y shape and communicates with the pop-up discharge part 200, the upper discharge part 120, and the fan assembly 131, respectively.

The flow path switching power unit 141 and the flow path switching member 142 that can be rotated by the power is positioned inside the flow path guide 150.

As shown in FIG. 3, the flow path switching member 142 blocks communication with the pop-up discharge part inserting part 126, or blocks communication with the upper discharge part 120 as shown in FIG. 4, or pop-up discharge part as shown in FIG. 5. The insertion unit 126 and the upper discharge unit 120 can be rotated so as not to block the communication.

As shown in FIG. 3, when the flow path switching member 142 blocks communication with the pop-up discharge part inserting part 126, all of the purified air is discharged through the upper discharge part 120. As shown in FIG. 4, when the flow path switching member 142 blocks communication with the upper discharge part 120, all of the purified air is discharged through the pop-up discharge part 200. When not communicating with any one as shown in Figure 5 is discharged through both the upper discharge portion 120 and the pop-up discharge portion (200).

The popup power unit 210 provides power for the popup. The popup power unit 210 is firmly fixed to another structure of the air cleaner, and includes a popup power member 211 and a popup first gear 212 rotated thereby.

The outer housing 250 and the inner housing 240 may be inserted into the pop-up discharge part casing 220, and are fixed to the other structure of the air cleaner by the fixing part 221. The upper and lower surfaces are open. The inner housing 240 and the outer housing 250 which will be described later are lifted through the open top surface. The open lower surface communicates with the flow path guide 150 to allow the air purified by the filter assembly 115 to flow into the pop-up discharge unit 200.

The pop-up discharge part casing 220 includes a plurality of pop-up guide grooves 229 which are formed as grooves in the up-down direction on the inner surface thereof and which can be moved up and down by inserting the pop-up guide 259 of the outer housing 250. By the pop-up guide groove 229, even when the pop-up power member 211 is powered, the rotation of the outer housing 250 is restricted and lifted.

The pop-up screw unit 230 is a structure that can rotate without lifting. The pop-up screw unit 230 includes a pop-up screw 233 having a screw thread on the outside and a pop-up second gear 232 positioned at the bottom thereof. The popup second gear 232 meshes with the popup first gear 212.

The inner housing 240 and the outer housing 250 are shown well in FIGS. 6 and 9. In FIG. 6, the upper surface of the outer housing 250 is omitted for explanation.

The inner housing 240 and the outer housing 250 are elevated together when the pop-up discharge unit 200 is elevated. 7 shows the pop-up discharge part 200 in the raised state. That is, when the pop-up power member 211 of the pop-up power unit 210 applies power, the outer housing 250 is raised. At this time, the inner housing 240 rises together, and the pop-up screw unit 230 rotates. The pop-up discharge part casing 220 is fixed and does not rise or rotate. The same is true when descending.

In addition, the inner housing 240 and the outer housing 250 are concentric, and the inner housing 240 is rotatable relative to the outer housing 250. In detail, the outer housing 250 rotates only the inner housing 240 without being rotated. By the relative rotation, the wind direction of the air discharged from the pop-up discharge unit 200 is controlled. Details will be described later.

The inner housing 240 may include a wind direction control power member 241 for providing power for rotation of the inner housing 240, a wind direction control first gear 242 rotated by the wind direction control power member 241, and an inner housing ( A guide groove 244 for limiting the rotation range of the 240 and the opening 245 through which air flows.

The guide groove 244 is provided on the upper surface of the inner housing 240 by a predetermined angle, thereby limiting the rotation of the inner housing 240 by the corresponding angle. That is, the guide groove 244 is inserted into the protrusion 254 (see Fig. 9) of the outer housing 250, the rotation is limited because the guide groove 244 that rotates with respect to the fixed protrusion 254 is caught. .

The opening 245 is provided only on a part of the outer surface (ie, the side surface) of the inner housing 240 to allow air that flows from below to reach the outside. The air passes only to the place where the opening 245 is located, and the passed air is discharged to the outside through the pop-up discharge grill 255. Using this principle, the wind direction is controlled.

When the inner housing 240 rotates, all of the parts provided in the inner housing 240 rotate together. That is, when power is applied by the wind direction control power member 241, the wind direction control first gear 242 rotates about the gear center axis, and the inner housing 240 is fixed as the wind direction control second gear 252 engaged thereto is fixed. ) Rotates around the center of the outer housing 250, the wind direction control power member 241 as well as the wind direction control first gear 242 in accordance with the rotation of the inner housing 240. That is, the wind direction adjusting first gear 242 rotates about the center of the gear and also rotates about the center of the outer housing 250.

The outer housing 250 has a structure of lifting and lowering but not rotating. The operation unit 201 may be located on the upper surface of the outer housing 250, but the illustration is omitted in FIG. 6 and below.

The outer housing 250 is a pop-up screw 233 for raising the wind direction adjusting second gear 252, which is engaged with the wind direction adjusting first gear 242, and the outer housing 250 to help rotate the inner housing 240. Is inserted into the pop-up screw insertion portion 253, the projection 254 is inserted into the guide groove 244 to limit the rotation of the inner housing 240, the pop-up discharge grill 255 through which the purified air is discharged, and the outer housing It includes a pop-up guide 259 is inserted into the pop-up guide groove 229 so that the 250 is raised without rotating.

As illustrated in FIGS. 6 and 7, the wind direction adjusting second gear 252 is provided inside the upper surface of the outer housing 250. It may be provided to be fixed to the outer surface of the pop-up screw insertion portion 253, it is concentric with the outer housing 250. Even if the wind direction control first gear 242 rotates about the gear center axis, the wind direction control second gear 252 engaged thereto is fixed without rotation, so that the wind direction control first gear 242 is the center of the outer housing 250. Rotation around the inner housing 240 is rotated accordingly.

The pop-up screw inserting portion 253 is provided with a thread inside, which corresponds to the thread provided on the outer surface of the pop-up screw 233. When the pop-up screw inserting portion 253 inserted inside the pop-up screw inserting portion 253 rotates, the pop-up screw inserting portion 253 with which the threads are engaged with each other may also rotate, but the pop-up guide 259 and the pop-up guide groove 229 are rotated. Rotation is limited by the popup screw insertion portion 253 is raised. Accordingly, the outer housing 250 and the inner housing 240 connected thereto are raised at the same time.

The protrusion 254 is inserted into the guide groove 244 of the inner housing 240. As shown in FIG. 9, even when the inner housing 240 rotates, the rotation of the inner housing 240 is limited by a predetermined angle where the guide groove 244 is positioned by the protrusion 254. The guide groove 244 and the protrusion 254 may be provided in plurality.

The pop-up discharge grill 255 is a portion for discharging the purified air to the outside. The air purified by the filter assembly 115 flows through the open lower surface of the pop-up discharge part casing 220 into the inner housing 240, and discharges through the opening 240 and the pop-up discharge grill 255. do.

The pop-up guide 259 is a portion inserted into the pop-up guide groove 229 and is provided on the outer surface of the outer housing 250 and may be provided in plural.

Explanation of lifting method of pop-up discharge part

When power is applied to the pop-up power member 211 of the pop-up power unit 210, the pop-up first gear 212 rotates, and the pop-up second gear 232 engaged with the pop-up screw unit 230 and the pop-up screw unit 230 are provided. Pop-up screw 233 rotates.

When the pop-up screw 233 rotates, the pop-up screw insertion portion 253 and the outer housing 250 into which the pop-up screw 233 is inserted by the thread may rotate, but the pop-up guide 259 of the outer housing 250 may rotate. The rotational movement is limited because of the insertion into the pop-up guide groove 229. Therefore, the pop-up screw insertion portion 253 rises along the thread and the outer housing 250 rises. At this time, the pop-up guide 259 also rises along the pop-up guide groove 229 formed as a groove in the vertical direction.

In addition, as the outer housing 250 rises, the inner housing 240 connected thereto also rises together.

In this way, the pop-up discharge unit 200 rises, and the same principle applies when falling.

Explanation of the wind direction switching method of the pop-up discharge part

When the wind direction control first gear 242 is rotated by the power of the wind direction control power member 241 of the inner housing 240, the wind direction control second gear 252 is firmly fixed to the outer housing 250 and does not rotate. Since the wind direction adjusting first gear 242 rotates about the center of the wind direction adjusting second gear 252, that is, the center of the outer housing 250. Since the first wind gear 242 is provided in the inner housing 240, the inner housing 240 rotates about the center of the outer housing 250.

However, since the protrusion 254 of the outer housing 250 is inserted into the guide groove 244 of the inner housing 240, the rotation range is limited to a predetermined angle at which the guide groove 244 is formed.

The wind direction may be switched by the rotation of the inner housing 240. It demonstrates with reference to FIG.

The pop-up discharge grille 255 is located throughout the radial position and the opening 245 is located only over some radial angle. As shown in Figures 8 to 10, the opening 245 is located only at an angle of about 70 degrees radially, of course, this angle can be changed as much.

In a state arranged as shown in FIG. 10, air will be discharged in the direction of the large arrow shown in FIG. 10. At this time, if the inner housing 240 rotates in the direction of the small arrow, the position of the opening 245 is changed to change the wind direction of the discharged air.

Another embodiment of the pop-up discharge portion

Another embodiment of the pop-up discharge unit 200 will be described with reference to FIGS. 11 to 13.

Compared with the above-described embodiment, only the positions of the pop-up discharge grill 255 and the opening 245 are changed.

The pop-up discharge grille 255 is positioned over some radial angle. In the illustrated embodiment, the pop-up discharge grille 255 is positioned in four areas based on FIG. 13.

The opening 245 is divided into two groups. The first group is the openings 245a to 245d located at positions corresponding to the radial partial angles at which the pop-up discharge grille 255 is located. The second group is an opening 245f located between such openings 245a to 245d, that is, an opening 245f located at an angle at which the pop-up discharge grill 255 is not located. In the embodiment shown in Fig. 13, there are four openings 245a to 245d, and one opening 245f is not limited in number.

As shown in FIG. 13, in the state where the openings 245a to 245d of the first group are disposed corresponding to the respective positions of the pop-up discharge grille 255, they may be discharged in the radially forward direction as in the large arrow direction. . That is, the omnidirectional discharge mode is executed.

Although the arrangement of the openings is changed by the rotation of the inner housing 240, only the opening 245f of the second group may be disposed corresponding to some of the pop-up discharge grills 255. At this time, air is discharged only to the position of the opening portion 245f. This is because the pop-up discharge grille 255 is not positioned in the outer housing 250 corresponding to the openings 245a to 245d of the first group. That is, the concentrated discharge mode is executed. In the embodiment shown in FIG. 13, when the inner housing 240 rotates about 90 degrees counterclockwise, the air is discharged only upwards based on the drawing, so that the concentrated discharge may be performed.

Such a mode is combined with a mode for which one of the upper discharge part 120 and the pop-up discharge part 200 to be used as described above, thereby providing a user with a variety of customized air cleaning with a simple mechanical structure. It is especially preferable.

In the foregoing specification, the present invention has been described with reference to the embodiments shown in the drawings so that those skilled in the art can easily understand and reproduce the present invention. It will be appreciated that embodiments are possible. Therefore, the protection scope of the present invention will be defined by the claims.
