Description

The present invention relates to an air purifier, and more specifically, it is a humidified air purifier in which a water tank can be attached and detached. The present invention relates to an air purifier that is configured so that the water tank can be moved to a normal installation position in the process of mounting the water tub and can prevent the water tank from being erroneously installed.

An air purifier is a device that forcibly sucks polluted external air inside to purify it, and then discharges the purified filtered air to the outside. Recently, in order to increase the utilization of air purifiers, air purifiers with additional functions in addition to the air purification function have been introduced. An example of this is a humidified air purifier with a humidifying function.

Humidified air purifiers need to be managed such as cleaning the water tank to perform the humidifying function. For this reason, the water tank is generally provided in a removable form.

If the humidified air purifier provides a structure that allows the water tank to be attached and detached, there is a possibility that the user will remove the water tank during use and then reattach it, slightly deviating from the normal installation position in the housing. be. If the water tank is mispositioned in this way, the water tank and the water tub may not be properly attached, and it may be impossible to perform the humidifying function. Such inability to humidify can be easily resolved by the user by correcting the position of the aquarium, but if the user perceives this as a failure, unnecessary repair requests and unreasonableness to the product. Improvement is required as it can lead to image degradation.

On the other hand, the humidified air purifier that has been exhibited conventionally has a structure in which a water tank and a water tub are generally attached to and detached from the side surface of the air purifier. For example, the Korean published patent No. 10-2019-0029819 "humidified air purifier" of Duwinia Co., Ltd. has a structure in which a water tank 300 is attached and detached through a side surface of a main body 100 of an air purifier. Further, Korean Publication No. 10-2018-0073361 "humidifying air purifier" of Coway Co., Ltd. discloses a structure in which the water tank 130 can be attached to and detached from one side surface of the frame 120. When an air purifier is placed and used indoors, it is often difficult to secure a space for attaching and detaching the aquarium on its side due to other furniture, interiors, walls, and the like. Therefore, according to such a structure, there is an inconvenience that the air purifier must be moved from the installation position in order to attach / detach the water tank 130 in some cases.

In the air purifier 1 according to the embodiment of the present invention, the humidifying section 40 is arranged above the filter section 30. Along with this, the air purifier 1 can perform both functions as a humidifier as well as purifying the air. More specifically, the external air A1 flows into the intake port 121 formed in the lower portion of the front surface of the housing 10 of the air purifier 1 and is filtered by the filter unit 30 to be filtered by the filter unit 30 in the internal flow path of the air purifier 100. Depending on the setting, it is discharged by the filtered air A2 through the first discharge port 111 formed on the upper part of the housing 10 without passing through the humidifying portion 40, or is formed on the upper part of the front surface of the housing 10 through the humidifying portion 40 after filtration. 2 It is discharged by the filtered and humidified air A3 through the discharge port 122.

Referring to FIGS. 1 to 3, the air purifier 1 according to the embodiment of the present invention includes a housing 10, a blower unit 20, a filter unit 30, a humidifying unit 40, a guide unit 50, and a flow path setting unit 60. It is composed.

Hereinafter, each configuration of the air purifier 1 according to the embodiment of the present invention will be described in detail.

The housing 10 forms the outer shape of the air purifier 1. The housing 10 provides a space in which a ventilation unit 20, a filter unit 30, a humidifying unit 40, a guide unit 50, and a flow path setting unit 60 can be arranged. Further, on the outer surface of the housing 10, an intake port 121 into which the external air A1 flows, a first discharge port 111 for discharging the filtered air A2, a second discharge port 122 for discharging the filtered humidified air A3, and a water tub 43 described later are provided. A water tub insertion port 112 or the like for inserting the water tub is formed.

The housing 10 can include a housing body 11 and a front cover 12.

A first discharge port 111 and a water bucket insertion port 112 are formed on the upper surface of the housing main body 11. In this way, when the water tub insertion port 112 is provided on the upper surface of the housing 10, the water tub 43 of the humidifying portion 40 can enter downward through the water tub insertion port 112 and be mounted on the water tank 41 of the humidifying portion 40, and vice versa. When separated from the water tank 41, it can be pulled out toward the upper side of the air purifier 1.

Further, an intake port 121 for inflow of external air A1 is formed in the lower portion of the front cover 12, and a second discharge port 122 is formed in the upper portion of the front cover 12. In the embodiment of the present invention, the first discharge port 111 is formed in the form of a grill, and the intake port 121 and the second discharge port 122 are formed by a large number of through holes formed through the front cover 12. ing.

On the other hand, both sides of the front cover 12 are formed so as to extend rearward (toward the housing main body 11 in the drawing), and include the recessed portion 123 formed in the front portion on the upper side thereof. The invagination portion 123 prevents the filtered humidified air A3 to be discharged from receiving excessive flow path resistance at the second discharge port 122 to generate noise, and provides a passage through which a part of the filtered humidified air A3 can be discharged. This reduces noise in the process of using the air purifier 1.

In one embodiment of the present invention, the housing 10 has the shape of a square cylinder with the housing body 11 and the front cover 12 coupled to each other. Of course, the shape of the housing 10 is not limited by this, and may have different shapes. Further, the positions and shapes of the intake port 121, the first discharge port 111 and the second discharge port 122 can also be changed as needed. For example, the intake port 121 may be formed on a plurality of front, rear, left, and right surfaces of the housing 10 so that air can be sucked in various directions, and the positions and shapes of the first discharge port 111 and the second discharge port 122 may also be formed. Can be changed as needed.

The blower unit 20 provides the blower wind so that the external air A1 flows into the housing 10. Further, the blower portion 20 provides a flow force so that the air filtered inside the housing 10 is discharged to the outside. More specifically, in the blower unit 20, the external air A1 flowing into the intake port 121 becomes the filtered air A2 through the filter member 31 of the filter unit 30, and then toward the first discharge port 111 or the second discharge port 122. Provide wind power to flow. Specifically, the blower unit 20 may be configured to include a motor, an impeller, and the like.

The blower portion 20 is arranged behind the filter portion 30 on the lower side inside the housing 10. Of course, the position and form of the blower portion 20 are not limited to this, and may be changed as necessary in design.

The filter portion 30 is arranged on the lower side inside the housing 10 and filters the outside air A1 to create the filtered air A2. The filter unit 30 includes a filter member 31 through which the external air A1 passes and is filtered. Further, a pre-filter 32 provided with a plurality of inflow holes 32a through which the external air A1 passes may be arranged between the front of the filter member 31 and the rear of the front cover 12.

The filter member 31 is a ULPA (Ultra-Low Penetration Air) filter that collects and filters 0.1 to 0.3 μm ultrafine dust or 0.3 μm or more fine dust contained in air, and HEPA (High Efficiency). It may consist of a Particulate Air) filter, a dust filter such as a medium filter, or a functional filter that removes bacteria and microorganisms contained in the inhaled air.

On the other hand, in one embodiment of the present invention, the prefilter 32 is formed in a square grid shape. However, this is an example, and the pre-filter 32 is not limited to this, and can be formed in various forms depending on the dust collection efficiency.

The humidifying section 40 humidifies the filtered air A2 that has passed through the filter section 30. In the air purifier 100 according to the embodiment of the present invention, the humidifying section 40 is arranged on the upper side of the filter section 30. When the flow path is formed so that humidification is performed after filtration, the filtered air A2 filtered through the filter member 31 of the filter unit 30 flows into the humidifying unit 40, and the humidifying unit 40 supplies water to the filtered air A2. To form filtered humidified air A3.

Referring to FIGS. 2 to 5, the humidifying portion 40 of the air purifier 1 according to the embodiment of the present invention includes a water tank 41, a humidifying member 42, and a water tub 43.

The water tank 41 includes mounting portions 411 and 412 formed in the form of a container with an open top. The mounting portions 411 and 412 may include a first mounting portion 411 to which the humidifying member 42 is mounted, and a second mounting portion 412 to which the water tub 43 for supplying the water provided to the humidifying member 42 to the water tank 41 is mounted. can. The first mounting portion 411 and the second mounting portion 412 may be arranged adjacent to each other. Specifically, the first mounting portion 411 may be formed on one side of the water tank 41, and the second mounting portion 412 may be formed on the other side of the water tank 41 adjacent to the first mounting portion 411.

Further, the water tank 41 is detachably formed from the installation position inside the housing 10 to the outside of the housing 10. More specifically, in the embodiment of the present invention, the water tank 41 is detachably formed in front of the housing 10. Along with this, in the case of the embodiment of the present invention, even if there are other objects on the side surface of the air purifier 1 and the space is narrow, the water tank 41 is separated only from the front cover 12 at the position where the air purifier 1 is used. Since the water tank 41 can be attached and detached, the user can easily attach and detach the water tank 41.

On the other hand, the water tank 41 is provided with a water receiving unit 413 for storing the water overflowing from the water tank 41. The water receiving portion 413 prevents the water inside the water tank 41 from overflowing when an external force is applied when the water tank 41 is attached or detached or during the process of using the air purifier 1. The water receiving portion 413 may be provided in front of the water tank 41. Specifically, the water receiving portion 413 may be provided by being connected to the front of the water tank 41 so that the front side wall 41a of the mounting portions 411 and 412 of the water tank 41 becomes the rear side wall of the water receiving portion 413.

The height of the front side wall 413a of the water receiving portion 413 is formed to be the same as the height of the front side wall 41a of the mounting portions 411 and 412 of the water tank 41. In the embodiment of the present invention, the height of the front side wall 41a of the mounting portions 411 and 412 is formed so that the central portion is lower than the both side portions. The portion is formed lower than both sides. Such a structure makes it possible to maximize the capacity of the water receiver while minimizing the flow path resistance applied to the filtered humidified air A3 that has passed through the humidifying member 42.

On the other hand, as best shown in FIG. 2, in the embodiment of the present invention, a groove 113 is formed at a predetermined position on the inner surface of one side wall and the other side wall of the housing 10 forming the installation position, and the water tank 41 is formed. A protrusion 414 formed so as to be inserted into the groove 113 at the installation position may be formed on the outer surface of one side wall and the other side wall.

Through such a groove 113 and the protrusion 414, the user can easily grasp whether or not the water tank 41 is correctly positioned at the set installation position when the water tank 41 is inserted. Of course, the groove 113 and the protrusion 414 may be formed opposite to each other. In other words, it is possible that protrusions are formed at predetermined positions on the inner surface of one side wall and the other side wall of the housing 10, and grooves are formed on the outer surface of the one side wall and the other side wall of the water tank 41.

The humidifying member 42 is mounted on the first mounting portion 411 and receives water from the water tank 41 to supply water to the filtered air A2. The humidifying member 42 carries out humidification by a vaporization type (blower type) using the water supplied to the first mounting portion 411 of the water tank 41. In the embodiment of the present invention, the humidifying member 42 is installed behind the second discharge port 122 along with the front surface of the housing 10.

The humidifying member 42 is arranged after the blower portion 20 in the air flow path. When the humidifying member 42 is located in front of the blower portion 20 in the air flow path, the air that has passed through the humidifying member 42 and has a high humidity passes through the blower portion 20, which causes a failure of the blower portion 20. Problems can occur. When the flow path is formed in the humidification mode by the flow path setting unit 60 described later, the external air A1 flowing in by the operation of the blower unit 20 becomes the filtered air A2 through the filter member 31 of the filter unit 30, and then humidifies. It is discharged as filtered humidified air A3 through the second discharge port 122 via the member 42.

On the other hand, in the air flow path, the filter unit 30 is arranged in the front stage of the air blower unit 20, and the humidifying member 42 is arranged in the rear stage of the air blower unit 20, so that only the air cleaning function is performed by setting the flow path of the flow path setting unit 180. If this is the case, the flow of the air filtered by the filter unit 30 to the humidifying member 42 is restricted, and the air cleaning efficiency can be increased. Along with this, even if the impeller provided in the blower unit 20 is driven with a relatively low RPM and low power, a sufficient discharge amount can be secured and noise can be reduced.

The humidifying member 42 may be configured to have a material or shape having excellent hygroscopicity so that the water contained in the water tank 41 can be sufficiently absorbed. For example, the humidifying member 42 may have a structure of being immersed in water contained in the water tank 41. However, the humidifying member 42 is not limited to the above-mentioned structure, and if vaporization-type humidification is possible, various known vaporization-type humidification structures such as a rotary-driven disk form may be used. good.

The water tub 43 is mounted on the second mounting portion 412 to supply water to the water tank 41. The water supplied by the water tub 43 is supplied to the first mounting portion 411 of the water tank 41 to immerse the humidifying member 42. In an embodiment of the present invention, the water tub 43 includes a water tub body 431 for accommodating water for humidification and a valve member 432 which is opened and closed so as to allow water contained in the water tub body 431 to be discharged. ..

The water tub 43 has a structure separable from the air purifier 1 so that the inside of the water tub body 431 can be easily filled with water. Further, the valve member 432 may be installed with a cap structure screwed to the inlet (injection port) of the water tub body 431.

The valve member 432 includes an opening / closing portion 432a that is elastically supported by an elastic means (for example, a spring), and the opening / closing portion 432a is maintained in a closed state when the opening / closing portion 432a is not pressurized, and the opening / closing portion 432a is pressurized. In the state, it can have a mechanical valve structure that keeps it open. The details related to the opening of the opening / closing portion 432a through pressurization and the closing by releasing the pressurizing state will be described later.

The guide portion 50 is formed so as to project upward around the second mounting portion 412 of the water tank 41 in which the water tub 43 is mounted. The guide portion 50 is pressurized by the water tub 43 when the water tub 43 enters the periphery of the second mounting portion 412 in a state where the water tank 41 is separated from the installation position within a predetermined range and arranged inside the housing 10. When the guide portion 50 is pressurized by the water tub 43, the water tank 41 moves in the installation position direction due to the pressing force provided to the guide portion 50.

The guide portion 50 may be formed behind the second mounting portion 412 when the front-back direction of the air purifier 1 into which the water tank 41 is inserted is used as a reference. Along with this, if the water tank 41 is erroneously placed inside the housing 10 by moving forward from the normal installation position by a predetermined range, the water tank 41 guides when the water tub 43 enters the periphery of the second mounting portion 412. It is pressurized by the water tub 43 that comes into contact with the portion 50 and can move to a fixed position behind.

The guide portion 50 can include any one or more of the first guide member 51 and the second guide member 52.

The first guide member 51 may be formed of a wall body extending forward from the rear side wall 41b of the mounting portions 411 and 412. Specifically, the first guide member 51 may be formed of a wall body extending forward from the rear side wall 41b of the second mounting portion 412 of the water tank 41.

The first guide member 51 may be provided with an inclined portion 51a on the upper surface thereof, which is inclined upward from the front end portion to the rear side. When the first guide member 51 includes the inclined portion 51a inclined upward from the front end portion as described above, the valve member 432 portion of the water tub 43 is in the process of the water tub 43 entering the second mounting portion 412 of the water tank 41. Can effectively provide the water tank 41 with a rearward moving force while riding on the inclined portion 51a and descending.

The second guide member 52 is provided around the second mounting portion 412, and in a pressed state, opens the flow path between the water tub 43 and the water tank 41 to supply the water in the water tub 43 to the water tank 41 and press it. It can be formed by a flow path switch that closes the flow path between the water tub 43 and the water tank 41 in the unfinished state. The second guide member 52 is pressurized by the water tub when the water tub 43 enters the periphery of the second mounting portion 412 in a state where the water tank 41 is separated from the installation position within a predetermined range and arranged inside the housing 10. The head portion 521 is provided at the upper end. At this time, the head portion 521 of the second guide member 52 may be arranged behind the second mounting portion 412 to which the water tub 43 is mounted.

The head portion 521 of the second guide member 52 has the water tank 41 separated from the installation position in front of the housing 10 by a predetermined range and is arranged inside the housing 10, and the water tub 43 enters the periphery of the second mounting portion 412. If it is pressurized by the water tub 43, the water tank 41 moves backward by the pressing force.

The head portion 521 of the second guide member 52 can be provided with an inclined portion 521a formed so as to incline downward from the inside toward the second mounting portion 412. When the head portion 521 of the second guide member 52 includes the inclined portion 521a inclined downward from the inside to the outside in this way, the valve member of the water tub 43 is in the process of the water tub 43 entering the second mounting portion 412 of the water tank 41. The 432 portion can effectively provide the water tank 41 with a rearward moving force while riding on the inclined portion 521a and descending.

In the embodiment of the present invention, although the head portion 521 of the first guide member 51 and the second guide member 52 is arranged behind the second mounting portion 412, they may be arranged side by side with each other. In this way, when the guide portion 50 includes all the first guide member 51 and the second guide member 52, the pressure transmitted by the water tub 43 is more reliable and stable when the water tub 43 enters the water tub 41 in the erroneously mounted state. It can be transmitted to 41, and as a result, the movement of the water tank 41 to the installation position can be more reliably guaranteed.

FIG. 6 is a drawing showing a state in which the water tank is arranged away from the installation position in the air purifier according to the embodiment of the present invention, and FIG. 7 is the first in the process of mounting the water tub in the water tank in FIG. It is a drawing which showed the state which pressurizes a guide member and a 2nd guide member, and moves a water tank to an installation position.

Looking at FIG. 6 in detail, when the water tank 41 is inserted in front of the air purifier 1, it is in an erroneous position because it was not sufficiently pressed to a fixed position, and it is in a fixed position behind the first mounting portion 411. The first mounting portion 411 and the second mounting portion 412 are separated forward from the fixed position reference line P2 of the reference line P1 and the second mounting portion 412 by a predetermined distance, respectively.

In such a state, if the water tub 43 is mounted without moving to the originally set installation position, the water tub 43 is not mounted in the fixed position, so that the humidifying function cannot be normally performed.

Hereinafter, the operation of the air purifier 1 according to the embodiment of the present invention in the cleaning mode, the humidifying mode, and the drying mode will be described with reference to FIGS. 11 to 13.

First, as shown in FIG. 11, in the clean mode, the flow path setting unit 60 is positioned in the vertical direction so as to allow the filtered air A2 to flow in the direction of the first discharge port 111 formed in the upper part of the housing 10. As described above, when the body portion 61 of the flow path setting portion 60 is located in the vertical direction, the filtered air A2 blown from the blower portion 20 is the first formed on the upper portion of the housing 10 by the flow path resistance of the humidifying member 42. It is guided to be discharged through the discharge port 111.

At this time, since the pressurizing portion 63 of the flow path setting portion 60 is separated from the head portion 521 of the second guide member 52, the pressing portion 522 of the second guide member 52 adds the opening / closing portion 432a of the valve member 432. No more pressure. Therefore, the opening / closing portion 432a is maintained in a closed state, and water is not supplied from the water tub 43 to the water tank 41.

Next, as shown in FIG. 12, in the humidification mode, the flow path setting portion 60 is arranged so as to be inclined so that the filtered air A2 rising from the lower part of the housing 10 is guided to the humidification portion 40 side. The flow of air to the discharge port 111 side is blocked.

In this case, the upper end of the body portion 61 of the flow path setting portion 60 is adjacent to the internal partition wall W that partitions the air flow path of the housing 10, and the lower end is adjacent to the opposite side of the partition wall W. The rising air is blocked, and the flowing air flows into the humidifying portion 40 through the through hole WH formed in the partition wall W. Along with this, the air blown by the blower unit 20 becomes the filtered humidified air A3 humidified through the humidifying member 42 of the humidifying unit 40, and can be discharged to the outside of the housing 10 through the second discharge port 122.

At this time, the pressurizing portion 63 of the flow path setting portion 60 comes into contact with the head portion 521 of the second guide member 52 to pressurize the head portion 521. Therefore, the head portion 521 of the second guide member 52 has a rotation shaft. The pressing portion 522 moves downward with reference to the portion 524, and the pressing portion 522 moves upward with reference to the rotation shaft portion 524. Along with this, the pressing portion 522 of the second guide member 52 pressurizes the opening / closing portion 432a of the valve member 432 upward, and the opening / closing portion 432a moves upward. Therefore, the opening / closing portion 432a is opened and water is supplied from the water tub 43 to the water tank 41.

On the other hand, as shown in FIG. 13, the flow path setting unit 60 can have a third position (drying mode position) located between the cleaning mode position and the humidifying mode position. In such a case, the humidifying member 42 and / or the water tank 41 may be dried.

Specifically, the upper end of the flow path setting unit 60 is slightly separated from the partition wall W that partitions the air flow path, and the lower end is slightly separated from the opposite side of the partition wall W, so that some air is on the upper side. A part of the air flows into the humidifying portion 40 through the through hole WH formed in the partition wall W. Along with this, the air passing through the humidifying member 42 can carry out the drying of the humidifying member 42. Further, the humidifying member 42 can have a structure capable of absorbing the water contained in the water tank 41, and in such a case, the water contained in the water tank 41 can be dried by drying the humidifying member 42. ..

Further, when the flow path setting unit 60 rotates from the position of the humidification mode to the drying mode, the contact between the pressurizing unit 63 of the flow path setting unit 60 and the head portion 521 of the second guide member 52 is released. The opening / closing portion 432a provided in the valve member 432 is in a closed state, and the supply of water from the water tub 43 to the water tank 41 is cut off.

At this time, in order to increase the drying efficiency, the position of the flow path setting unit 60 in the drying mode may be set so as to sufficiently secure the amount of air blown to the humidifying unit 40. For example, the position of the flow path setting portion 60 in the drying mode is set in the humidification mode so that the contact between the pressurizing portion 63 and the head portion 521 of the second guide member 52 may be released and the opening / closing portion 432a may be closed. It can be done to the extent that it is slightly rotated from the position.
