Description

Air purifier with swirling air suction function

The present invention relates to an air purifier, and more particularly, to an air purifier that improves indoor air quality by purifying contaminated air in a home or commercial indoor space.

Conventionally, air purifiers commonly used in homes or commercial indoor spaces take a method of purifying pollutants by putting purification means such as filters in the air intake unit based on the range hood system. The range hood system is a system in which a simple prefilter is placed in front of it and the adjacent air is forcibly drawn through a sirocco fan to create a flow of air through a pressure difference and discharge it to the outside.

That is, since the range hood system of the Sirocco fan method does not cover contaminated or clean air, and inhales the air immediately adjacent to the Sirocco fan, the cooking table is placed at a certain distance, and thus occurs during the cooking process of food. There is a limit to removing pollutants by completely inhaling food odors or combustion gases before spreading indoors.

The air purifier employing such a sirocco fan-type range hood system also has a problem in that the purification diffusion speed is very slow due to the eddy flow in which only the surrounding air is sucked and purified, and the purified air is introduced again.

In addition, as the range hood system does not quickly and completely capture and discharge odors generated in the process of cooking food in the kitchen, which is an area of the indoor living space, the cooking odor spreads indoors and damages the health of residents. It is also unpleasant with a bad smell.

In addition, households with pets are increasing, and as pets live with residents in a structure like a closed apartment, the secretions and odors emitted by the pets spread throughout the room to offend visitors or to residents with a high concentration of odor. It is a factor that harms the health of people. There are a number of products in the form of a spraying agent to remove such bad odors, but they are only effective when spraying the spraying agent, and they are not able to remove persistent or fundamentally bad odors.

An object of the present invention is to provide an air purifier capable of quickly purifying the polluted air in the entire space by expanding the flow area capable of purifying indoor polluted air as much as possible regardless of surrounding obstacles without staying around.

The air purifier having a vortex air suction function according to the present invention for achieving the above object is a vortex forming housing, a vortex air intake fan, a filter housing, a dust collection filter set, a discharge housing, a discharge fan, and a deodorization filter. , And a controller. The vortex-forming housing has a shape in which the width of the internal space increases from the air outlet to the air inlet. As the vortex air intake fan rotates within the vortex-forming housing, it interacts with the inner surface of the vortex-forming housing to form a vortex in the surrounding air and send it from the air inlet. It has an inner wing for sucking the, and a suction motor for rotating the outer wing and the inner wing. The filter housing receives air from the air outlet of the vortex-forming housing through the inlet to the inner space and discharges it through the outlet. The dust collection filter set collects and removes dust in the air passing through the inner space of the filter housing. The discharge housing receives air from the outlet of the filter housing through the inlet to the inner space and discharges it through the outlet. The exhaust fan delivers air supplied into the exhaust housing to the outlet of the exhaust housing. The deodorizing filter removes odors in the air supplied to the filter housing. The controller controls the driving of the vortex air intake fan and the exhaust fan, and controls various sensors, lamps, and functions of speakers.

According to the present invention, it can be used to quickly purify contaminated indoor air, and it is possible to increase the purification speed of indoor air by expanding the flow area of the air purifier as much as possible to inhale and purify air from a distant area rather than adjacent air. .

According to the present invention, odors that are spread over the entire space are removed so that indoor residents can live in a healthy and comfortable environment. According to the present invention, it is possible to improve the limitation of removing only the smell of the local area due to the limitation of the existing eddy air purifier, the smell of food in the kitchen and the bad smell of pets that exist in the indoor space. In addition, according to the present invention, unlike the method of one-time removal of odors in the form of conventional sprays, odors are also removed in a continuous, fundamental and eco-friendly way for the entire space, and discarded in an environment-friendly manner even after using a deodorizing filter. can do.

1 to 5, the air purifier 100 according to an embodiment of the present invention includes a vortex forming housing 110, a vortex air suction fan 120, a filter housing 130, and a dust collection filter set. It includes 136, a discharge housing 140, a discharge fan 146, a deodorizing filter 150, and a controller 160.

The vortex-forming housing 110 has a shape in which the width of the internal space increases from the air outlet to the air inlet. For example, as the air inlet of the vortex forming housing 110 is located above the air outlet, the inner space of the vortex forming housing 110 forms a concentric circle and gradually widens as it goes from the flat bottom with the center open to the upper opening. The side may be made in an inclined shape. That is, the vortex-forming housing 110 may be formed in a shape in which a cut hollow cone is inverted, but the center of the lower surface is opened and the upper surface is opened as a whole.

In this case, in the vortex forming housing 110, the bottom central opening forms the air outlet, and the upper opening forms the air inlet. The vortex forming housing 110 of this shape surrounds the outer wing 121 of the vortex air intake fan 120 so that the wind caused by the rotation of the outer wing 121 can create a vortex in the surrounding air. Meanwhile, another example related to the shape of the vortex-forming housing 110 will be described later.

The vortex forming housing 110 may include a guide piece 111. The guide piece 111 is formed to extend in the same cross-sectional area from the air inlet of the vortex forming housing 110 to prevent the diffusion of vortex flow. For example, the guide piece 111 is made of a hollow cylinder having a concentric circle with the vortex forming housing 110, thereby minimizing the vortex flow created by the outer blade 121 from spreading to the outer region of the vortex forming housing 110 At the same time, it extends to a long distance and induces it to collect contaminated air from a distant place.

Accordingly, it may be prevented from causing obstacles or discomfort to objects or people in the outer region of the vortex-forming housing 110. The guide piece 111 may extend to a height of 10 mm or more from the air inlet of the vortex forming housing 110.

The vortex-forming housing 110 may be formed in a fan shape in which the angle θ formed between the bottom and the side is greater than 125° in a longitudinal section. The height of the vortex forming housing 110 may be set in connection with the heights of the inner wing 122 and the outer wing 121.

The inner surface of the vortex-forming housing 110 may be formed in a smooth shape, but is formed in an uneven shape to further promote vortex flow. For example, protruding bands 112 may be formed on the inner surface of the vortex forming housing 110. The protruding bands 112 are arranged to be spaced apart from each other in the height direction of the vortex forming housing 110. Each of the protruding bands 112 is formed continuously along the circumferential direction in an embossed shape on the inner surface of the vortex forming housing 110.

Accordingly, the inner surface of the vortex-forming housing 110 may be formed in a shape in which irregularities are repeated along the height direction. The protruding band 112 may be formed discontinuously along the circumferential direction of the vortex forming housing 110. Meanwhile, other examples related to the inner shape of the vortex-forming housing 10 will be described later.

The vortex air suction fan 120 includes an outer blade 121, an inner blade 122, and a suction motor 123. As the outer blade 121 rotates within the vortex-forming housing 110, it interacts with the inner surface of the vortex-forming housing 110 to form a vortex in the surrounding air and send it from the air inlet. That is, the outer wing 121 pushes air in a direction opposite to the direction in which the inner wing 122 sucks air.

The outer wing 121 may be formed in a form in which the outer wing pieces 121b are radially arranged along the outer circumference of the circular rim 121a. The outer wing pieces 121b each protrude from the outer periphery of the circular rim 121a with a predetermined thickness. The outer blade piece 121b is set to have a length along the axial direction of the circular rim 121a longer than the length along the circumferential direction of the circular rim 121a.

The protruding end of the outer wing piece 121b may have a structure connected to two convex curved surfaces of different shapes. On the other hand, the outer wing pieces (121b) may be formed evenly arranged and formed in the same shape, while coexisting in various forms, it is possible to quickly create a vortex flow.

The outer wing 121 cooperates with the vortex-forming housing 110 surrounding the outer periphery to flow the air outside the circular rim 121a in a direction opposite to the direction of the air pushed by the inner wing 122 to maximize the vortex air. Make a lot and send it away. In addition, the outer wing 121 serves to induce the air that vortex flows at a long distance to be sucked into the low pressure region created by the inner wing 122.

As the inner wing 122 rotates inside the outer wing 121, the surrounding air is sucked from the air intake port. The inner wing 122 rotates in one direction and pushes the ambient air from the air intake port to the air outlet port to inhale it. The inner wing 122 may be of an axial flow type that transports air in the same direction as the axial direction. That is, the inner wing 122 may be formed in a form in which the inner wing pieces 122b are radially arranged along the outer circumference of the hub 122a. The hub 122a is coaxially fixed to the drive shaft of the suction motor 123. Accordingly, the inner blade 122 rotates as the hub 122a rotates by the rotational force of the drive shaft of the suction motor 123.

The inner wing pieces 122b are formed in a shape that sucks ambient air from the air intake port and sends it to the air outlet port when rotating. The inner wing piece (122b) is formed in the shape of the wing of the propeller and has a relatively large area, so that it is possible to inhale as much air as possible. The number and shape of the inner wing pieces 122b are not limited to those illustrated, and may be appropriately set according to the conditions of the air outlet.

Each of the inner wing pieces 122b is connected to the inner circumference of the circular rim 121a with the protruding ends thereof, so that the hub 122a and the circular rim 121a may be mutually supported. As another example, the inner wing pieces (122b), each protruding end is separated from the circular rim (121a), the hub (122a) and the circular rim (121a) may be connected to each other by separate supports may be supported. Accordingly, when the inner blade 122 rotates in one direction by the suction motor 123, the outer blade 121 may rotate together in the same direction as the rotation direction of the inner blade 122.

The suction motor 123 rotates the outer blades 121 and the inner blades 122. In the suction motor 123, the body may be fixed in the filter housing 130 while the drive shaft is coaxially fixed to the hub 122a of the inner wing 122. The suction motor 123 rotates the outer blade 121 together with the inner blade 122 by providing rotational force to the hub 122a of the inner blade 122 through a drive shaft.

The vortex air intake fan 122, together with the vortex-forming housing 110, expands the air flow area of the air purifier 100 as much as possible to inhale and purify the air in a distant area rather than the adjacent air, thereby purifying the purifying speed of indoor air. To be able to increase.

The filter housing 130 receives air from an air outlet of the vortex-forming housing 110 through an inlet to an internal space and discharges it through an outlet. The filter housing 130 mounts a dust collection filter set 136 on an air passage discharged from an inlet through an inner space to an outlet. The inlet of the filter housing 130 is connected in communication with the air outlet of the vortex forming housing 110. The outlet of the filter housing 130 is formed in the center of the bottom.

The inner space of the filter housing 130 may be partitioned by a support plate 131 disposed close to the inlet side. The support plate 131 may support the body of the suction motor 123 in the center of the upper surface. The support plate 131 may send air supplied from the inlet of the filter housing 130 to the outlet of the filter housing 130 through edge holes.

The dust collection filter set 136 collects and removes dust in the air passing through the inner space of the filter housing 130. The dust collection filter set 136 may include a collision adsorption cloth 132, a prefilter 137, and a HEPA filter (High Efficiency Particulate Air filter 138). The pre-filter 137 first collects and removes dust in the air supplied into the filter housing 130. The HEPA filter 138 secondly collects and removes dust in the air that has passed through the pre-filter 137.

As shown in FIG. 12, the collision adsorption cloth 132 is disposed in the filter housing 130 to face the air outlet of the vortex-forming housing 110 to collect pollutants in the air supplied from the air outlet. The collision adsorption cloth 132 may be made of a fiber material or the like.

The dust collection filter set 136 may be wrapped and supported by the support frame 133. The support frame 133 may be formed in a form in which the lid is blocked and the side plate and the bottom plate are partially opened, or the lid and the bottom plate are separated, and wrap and support the dust collection filter set 136. The collision adsorption cloth 132 may be attached to the upper part of the lid of the support frame 133. In this case, as shown in FIG. 13, the support plate 131 may have exposed holes for exposing the collision adsorption cloth 132 around a central portion supporting the body of the suction motor 123. In addition, the support plate 131 has edge holes for sending air to the side of the dust collection filter set 136 around the exposed holes.

The first physical part where the pollutant sucked through the vortex-forming housing 110 passes through the air outlet and collides for the first time is the upper part of the lid of the dust collecting filter set 136, and the collision adsorption cloth 132 on the upper part of the lid is By primarily collecting pollutants (eg, liquids or thick particulate matter) in the collision process, the filtering efficiency of the dust collection filter set 136 and the deodorization filter 150 and the filtering efficiency of the dust collection filter set 136 and the deodorization filter 150 It plays a role in increasing the lifespan. The collision adsorption cloth 132 may be configured in a form detachable from the top of the lid so that it can be replaced with a new adsorption cloth at any time during the replacement process of the dust collection filter set 136 and the deodorization filter 150.

The pre-filter 137 may have a hollow cylinder shape. The pre-filter 137 may be disposed in the filter housing 130 in a state spaced apart from the inner circumferential surface of the filter housing 130 and the hollow lower side communicates with the outlet of the filter housing 130. The pre-filter 137 may be supported by a lower end contacting the inner bottom of the filter housing 130 and an upper end contacting the lower surface of the support plate 131. The HEPA filter 138 may be formed of a hollow cylinder having the same length as the prefilter 137 and may be coaxially inserted into the hollow of the prefilter 137 and disposed.

The discharge housing 140 receives air from an outlet of the filter housing 130 through an inlet to an internal space and discharges it through the outlet. The inlet of the discharge housing 140 is connected in communication with the outlet of the filter housing 130. The outlet of the discharge housing 140 may be formed on the side of the discharge housing 140. The discharge housing 140 mounts a discharge fan 146 in the inner space.

The exhaust fan 146 sends air supplied into the exhaust housing 140 to the outlet of the exhaust housing 140. The discharge fan 146 sucks air from the inlet of the discharge housing 140 as the discharge blade 147 rotates in one direction by the discharge motor 148 and sends it to the outlet of the discharge housing 140. 140). The exhaust fan 146 may be formed of a sirocco fan or the like.

The deodorizing filter 150 removes odors in the air supplied to the filter housing 130. The deodorizing filter 150 may be disposed in the filter housing 130. The deodorization filter 150 may remove odors in the air that has passed through the dust collection filter set 146. The deodorizing filter 150 may be formed of a hollow cylindrical shape, and may be coaxially inserted into the hollow of the HEPA filter 148 and disposed.

The deodorizing filter 150 may be formed in a sintered shape after natural charcoal is pulverized, molded and compressed. The deodorizing filter 150 may be made into a single lump by crushing white coal natural charcoal made of wood such as birch to a small size, compression molding, and then sintering. Accordingly, the deodorizing filter 150 is an eco-friendly filter, and removes bad smells such as odors generated in the kitchen and pet secretions that are spread throughout the room to make the indoor air pleasant.

As a comparative example, deodorizing filters for odor removal used in existing air purifiers are mostly coated on a cell-shaped surface made of paper such as honeycomb or triangular shape, or a multi-continuous cell-shaped space. The structure is filled with activated carbon in the form of a pellet and collects odors.

The deodorizing filter coated with a carbon material has a problem in that the adsorption area is limited only to the surface, so that the odor removal is effective only at the beginning, and the adsorption capacity is saturated so that the function of removing odor cannot be continuously achieved.

The deodorizing filter made of activated carbon has a larger adsorption capacity than the coated adsorption filter, but the activated carbon is made of pellets and is filled in the frame. Therefore, if the frame is upright, since the activated carbon pellets are filled only at the bottom of the individual cells, air escapes without contact with the activated carbon into the empty spaces at the top of the individual cells, and accordingly, all air goes through the deodorization process. As it cannot be passed, only partial deodorization is achieved.

In addition, even if the activated carbon pellets are completely filled in individual cell spaces, air can escape to the empty space formed between the pellets and the pellets without being deodorized and spread out into the indoor space without being purified. The pellet-type activated carbon deodorization filter needs to be replaced when the deodorizing function is poor. The filter is divided into three parts: cell, pellet-type activated carbon, and mesh, so it is inconvenient to separate each material and incinerate when disposed of as garbage. It is not an environmentally good method because it has to be handled only.

On the other hand, the natural charcoal deodorization filter 150 of this embodiment is made by crushing charcoal having a porous structure (retaining a cross-sectional area of 90 pyeong per 1 gram of charcoal), which is the characteristic of natural charcoal, into small grains, molding, pressing, and sintering to form a single mass. Therefore, the surface area is wider with a very small space formed between the charcoal grains, and in the process of passing contaminated air through the charcoal, most of it comes into contact with the charcoal and is deodorized, thereby having a high deodorizing efficiency.

Since the natural charcoal deodorization filter 150 can be easily molded in various shapes to maximize the contact area with air, it has a large filtration area and has excellent internal adsorption capacity due to the many pores of charcoal, which is superior to other existing deodorization filters. Have. In addition, even after using the natural charcoal deodorization filter 150, it is a single lump, so there is no need to separate it, and it can be disposed of in an environment-friendly manner in various ways such as burial or incineration.

As another example, as shown in FIG. 6, the deodorizing filter 150 ′ may be disposed in the discharge housing 140. The deodorization filter 150 ′ may be disposed closer to the outlet side of the discharge housing 140 than the discharge fan 146. The deodorizing filter 150 ′ is formed to have the same size as the outlet of the discharge housing 140, and may be exposed to the outside while being inserted into the outlet of the discharge housing 140.

Since the deodorizing filter 150 ′ is disposed on the outer surface of the discharge housing 140 and exposed, not only removes odors in the air introduced into the air purifier 100, but also natural when the air purifier 100 is not operated. It can have the effect of collecting and removing odors in the indoor air caused by convection.

The controller 160 controls the vortex air suction fan 120 and the discharge fan 146. The controller 160 may operate or stop the vortex air intake fan 120 and the exhaust fan 146 according to a power on/off command input through an input unit 161 such as a user interface. In this case, the controller 160 may control the operating speeds of the vortex air intake fan 120 and the exhaust fan 146 based on information provided from the dust sensor 162 and the odor sensor 163.

That is, based on the information provided from the dust sensor 162 and the odor sensor 163, the controller 150 increases the operation speed of the vortex air intake fan 120 and the discharge fan 146 step by step as the pollution degree increases, As the pollution level decreases, the operating speed of the vortex air suction fan 120 and the discharge fan 146 may be gradually reduced. The controller 150 may be incorporated in the filter housing 130, including an air purification processor, or the like.

As shown in FIG. 7, concave bands 212 may be formed on the inner surface of the vortex forming housing 110. The concave bands 212 are arranged to be spaced apart from each other in the height direction of the vortex forming housing 110. The concave bands 212 are formed continuously along the circumferential direction in an intaglio shape on the inner surface of the vortex forming housing 110, respectively. Accordingly, the inner surface of the vortex-forming housing 110 may be formed in a shape in which irregularities are repeated along the height direction. The concave band 212 may be formed discontinuously along the circumferential direction of the vortex forming housing 110.

As shown in FIG. 8, concave bands 312 may be continuously formed on the inner surface of the vortex forming housing 110 in the vertical direction, respectively. The concave bands 312 are arranged to be spaced apart from each other in the circumferential direction of the vortex forming housing 110. Accordingly, the inner surface of the vortex forming housing 110 may be formed in a shape in which irregularities are repeated along the circumferential direction. The concave band 312 may be formed discontinuously along the vertical direction of the vortex forming housing 110.

As shown in (a) of FIG. 9, polygonal embossing 412 may be formed to protrude in an embossed shape on the inner surface of the vortex forming housing 110. The polygonal embossing 412 may be formed to be concave in an intaglio shape. The polygonal embossing 412 may be arranged at uniform intervals, but may be non-uniformly arranged.

As another example, as shown in (b) of FIG. 9, circular embossing 512 may be formed to protrude in an embossed shape on the inner surface of the vortex forming housing 110. The circular embossing 512 may be formed to be concave in an intaglio shape. The circular embossing 512 may be arranged at uniform intervals, but may be arranged non-uniformly. In addition, it goes without saying that the inner surface of the vortex-forming housing 110 may be formed in various uneven shapes.

On the other hand, as shown in (a) of FIG. 10, the vortex forming housing 110' has a convexly curved side so that the inner space forms a concentric circle as it goes from the flat bottom with the center open toward the upper opening. That is, it may be formed in the shape of a curved bowl in which the center of the bottom is opened. In the vortex forming housing 110 ′, the above-described guide piece 111 may be extended to the upper opening.

As another example, as shown in (b) of FIG. 10, the vortex forming housing 110 ″ has a lower portion formed in a curved bowl shape as in the above-described example, and an extension portion in which the upper portion is expanded in an inclined shape ( 110a") may be connected to the guide piece 111 as a medium. The above-described protruding band 112, concave bands 212 and 312, polygonal embossing 412, and circular embossing 512 may be formed on the inner surfaces of the vortex forming housings 110 ′ and 110 ″.

Meanwhile, as shown in FIG. 11, the air purifier 100 may include an active noise reducer 170. The active noise reducer 170 notifies the operation state according to the air quality by sound when the vortex air intake fan 120 and the exhaust fan 146 operate, and reduces noise. The active noise reducer 170 may include a microphone 171, a speaker 172, and a noise reduction processor 173.

The microphone 171 detects noise according to the operation of the vortex air intake fan 120 and the exhaust fan 146. The speaker 172 outputs sound for an operating state according to air quality, and outputs sound or music for noise reduction. The microphone 171 and the speaker 172 may be mounted on the filter housing 130 or the like.

The noise reduction processor 173 outputs, through the speaker 172, an operation state set according to the pollution level based on information provided from the dust sensor 162 and the smell sensor 163. The noise reduction processor 173 outputs sound or music for sound masking through the speaker 172 based on the information provided from the microphone 171, or outputs sound to cancel the noise through the speaker 172. Print it out. The noise reduction processor 173 may be mounted on the controller 160.

As a comparative example, the conventional air purifier displays the operating state by displaying the air condition as "good", "normal", "bad", etc. using an LCD screen or an LED indicator. In this case, there is a limit to knowing the state of air quality only when the user approaches the air purifier and sees it with his own eyes. In addition, noise may be generated when the operating conditions of the air purifier are strongly operated due to "poor" air quality.

The active noise reducer 170 of the present embodiment is the air purifier 100 immediately before spreading to the entire indoor space when the pollutant source has a concentration higher than the reference value, particularly when the food smell in the kitchen suddenly occurs or the smell of a pet is detected. It notifies by sound or music that is changed to the strongest clean processing state, and at the same time, it emits sound or music suitable for noise reduction, eliminating noise and improving the sensitivity of residents. Accordingly, the active noise reducer 170 uses a method of displaying the operating state of the air purifier 100 using a user's hearing rather than a visual element, so that user convenience and comfort can be felt.

In addition, the air purifier 100 may include an alarm 180. The alarm 180 notifies at least one of a sound and a time according to the approach of a person or an animal to the air purifier 100. The alarm 180 may include a proximity sensor 181, a speaker 182, a lamp 183, and an alarm processor 184.

The proximity sensor 181 detects the approach of a person or an animal with the air purifier 100. The speaker 182 outputs sound when a person or an animal approaches. The speaker 182 may be replaced with the speaker 172 of the active noise reducer 170. The lamp 183 outputs light when a person or an animal approaches. The lamp 183 may be formed of an LED lamp or the like. The proximity sensor 181, the speaker 182, and the lamp 183 may be mounted on the filter housing 130 or the like.

The alarm processor 184 outputs sound and/or light through the speaker 182 and/or lamp 183 when a person or animal approaches, based on the information provided from the proximity sensor 181. The alert processor 184 may be mounted on the controller 160.

Such an alarm 180 makes it possible to block access of a pet to the air purifier 100. That is, when the air purifier 100 is placed near the pet in order to remove the odor of the pet, the alarm 180 causes the pet to contact the air purifier 100, causing a problem in the safety of the air purifier 100. It makes it possible to prevent it from occurring.

The present invention has been described with reference to an embodiment shown in the accompanying drawings, but this is only illustrative, and those of ordinary skill in the art will understand that various modifications and other equivalent embodiments are possible therefrom. I will be able to. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
