Description

Air Purifier {AIR CLEANER}

The present invention relates to an air cleaner, and more particularly, to an air cleaner that removes moisture from the discharged air or adds an additive to the discharged air.

In general, the air purifier sucks contaminated indoor air to filter dust, odor particles, etc. contained in the air with a filter to purify the inhaled air with clean air. The air thus purified is discharged back to the outside of the air cleaner, that is, the room.

In other words, the air cleaner purifies the ambient air in which the air cleaner is installed while purifying the contaminated ambient air by discharging the clean air to the outside.

On the other hand, in recent years, air purifiers with additional functions so that the air purifier can perform a variety of functions have been released one after another. That is, air purifiers that perform various additional functions such as dehumidification function, antibacterial function, fragrance dissipation function, and vitamin discharge function have been released.

However, these functions are not always operated when the air cleaner is driven, but are operated as needed. Accordingly, the air cleaner is generally discharged from the air passage through which air processed by the additional function is discharged and the air from which only air cleaning is performed is discharged. A dual flow path with a flow path is adopted.

However, when a double flow path is employed in the air purifier, the flowing air is divided into double flow paths and discharged, so that the air volume of the discharged air is reduced.

In addition, only some of the air discharged from the air cleaner is processed by the additional function, and the remaining air is discharged from the air cleaner without the additional function, thereby reducing the effect of the additional function.

In other words, only a part of the air discharged from the air cleaner is dehumidified or only a part of the discharged air contains antibacterial substances, fragrant substances, vitamins, etc., so that antibacterial substances, fragrant substances and vitamins are evenly distributed to the outside air. There is a problem that can not spread while spreading.

An object of the present invention is to provide an air purifier capable of minimizing a decrease in the amount of air even if it performs a function of removing moisture from the discharged air or adding an additive to the discharged air.

The air purifier according to the present invention includes a main body housing having a discharge port through which the introduced air is discharged, a flow path part for guiding the air flowing by the blower to be discharged through the discharge port by forming an arc, and into the discharge port. One side is connected to one region of the flow path portion disposed adjacent to the discharge port so that some of the flowing air flows, and the other side is a circulation flow passage portion connected to the flow path portion so that air is re-introduced into the flow passage portion, and the circulation flow passage And a circulating air processing unit mounted to the unit to remove moisture from the flowing air or to add an additive to the air.

The air purifier may further include an opening and closing part provided at one side of the circulation flow path part to control inflow or blocking of air from the flow path part to the circulation flow path part.

The circulating air processing unit is installed in the mounting groove provided in the circulation flow path unit to absorb heat to one side and radiate heat to the other side, and installed on one side of the thermoelectric element to cool the air to condense moisture It can be provided with a cooling plate.

The circulating air processing unit may further include a water tank disposed at a lower portion of the cooling plate to introduce condensed water.

The water tank is formed in the circulation flow path portion is provided to be disposed in the water discharge hole for discharging moisture concave groove for temporarily storing the water falling from the cooling plate, the inlet hole is formed extending from the recess groove It may be provided.

The circulation air processing unit may be installed in a mounting groove provided in the circulation flow path unit, and may include an additive discharge unit configured to discharge the additive into air circulating by receiving the additive therein.

The additive discharge unit may be configured to include an additive receiving member having an opening therein and having an opening through which the vaporized additive is discharged.

The additive discharging unit may include a heating member disposed to be in contact with an outer surface of the additive receiving member to heat and vaporize the additive contained therein.

According to the present invention, dehumidification may be performed from the air discharged to the outside through the circulation air processing unit or an additive may be added to the discharged air. Due to the negative pressure difference, it is introduced into the circulating flow path part and then re-introduced into the flow path part to be mixed with the discharged air and discharged, thereby minimizing the reduction of the air volume by performing the function of adding dehumidification or additives.

In addition, the air treated by the circulating air processing unit is re-introduced into the flow path unit and mixed with the air discharged through the discharge port, thereby improving the diffusion efficiency of the antimicrobial substance, the fragrance emitting substance and the vitamin.

Hereinafter, with reference to the drawings will be described in detail a specific embodiment of the present invention. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventive concept. Other embodiments which fall within the scope of the inventive concept may be easily suggested, but are also included within the scope of the present invention.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Hereinafter, an air cleaner according to an embodiment of the present invention will be described with reference to the drawings.

1 is a block diagram illustrating an air cleaner according to an embodiment of the present invention, FIG. 2 is a front view illustrating the air cleaner shown in FIG. 1, and FIG. 3 is an enlarged view of part 'A' shown in FIG. 1.

1 to 3, as an example, the air cleaner 100 may include a main body housing 120, a blower 130, a flow path 140, a circulation flow path 150, and a circulation air processor 160. It includes.

The main body housing 120 has a discharge port 122 through which the incoming air is discharged. That is, the air introduced into the body housing 120 and purified by the filter unit (not shown) is discharged to the outside through the discharge port 122.

Meanwhile, the main body housing 120 includes a partition member 124 on which the blower 130 is installed, and the blower 130 is disposed behind the partition member 124 on a flow path of air. The air introduced by the blower 130 may no longer flow to the blower 130 by the partition member 124, but may flow to the discharge port 122.

The blowing unit 130 provides a suction force for introducing external air into the body housing 120.

Since the blower 130 corresponds to a configuration well known in the art, the drawings and detailed description thereof will be omitted. That is, the blowing unit 130 includes a driving motor for driving the blowing fan and the blowing fan to flow air by the rotation of the blowing fan.

The flow path part 140 guides the air flowing by the blower 130 to flow while forming an arc to be discharged through the discharge port 122.

On the other hand, the flow path portion 140 is provided on one side of the partition member 124 of the main body housing 120 and one side of the circular arc-shaped flow path forming member 142 and the flow path forming member 142 together with the air It may be provided with a guide member 144 to form a flow path.

The flow path forming member 142 is guided so that the air introduced into the flow path part 140 by the blower 130 flows while forming an arc to be discharged to the discharge port 122, and is opened to the discharge port 122.

In addition, the flow path forming member 142 and the guide member 144 may be arranged such that the communication hole 142a is formed such that air flowing through the circulation flow path part 150 flows back into the flow path part 140.

That is, the air flowing into the circulation flow path part 150 and flowing along the circulation flow path part 150 flows back into the flow path part 140 through the communication hole 142a and flow path part 140 by the blower 130. Mixed with the air introduced into the furnace.

In addition, the guide member 144 is formed to have a bent shape serves to guide the flowing air to the circulation flow path 150. That is, part of the air flowing along the flow path forming member 142 is guided by the guide member 144 toward the circulation flow path part 150.

The circulation flow path part 150 is connected to one region of the flow path part 140 disposed adjacent to the discharge port 122 so that a part of the air flowing into the discharge port 122 flows in, and the other side of the air flow path ( It is connected to the flow path portion 140 to be re-flowed to 140.

Looking in more detail on this, the circulation flow path 150 is provided with a circulating air inlet 152 is guided by the guide member 144, the air flowing in. In addition, since the circulation flow path 150 communicates with the flow path part 140 through the communication hole 142a, the air introduced into the circulation flow path 150 from the circulation air inlet 152 again passes through the communication hole 142a. It may flow into the flow path 140.

On the other hand, the circulation flow path unit 150 may be provided with a mounting groove 154 on which the circulation air processing unit 160 is mounted. That is, the mounting flow passage 150 may be provided with a mounting groove 154 in which the circulation air processing unit 160 for removing moisture from the air flowing along the circulation flow passage 150 is installed.

The circulating air processor 160 is mounted on the circulating flow path 150 to remove moisture from the air flowing. To this end, the circulating air processor 160 may include a thermoelectric element 162, a cooling plate 164, a heat sink 166, and a water tank 168.

The thermoelectric element 162 absorbs heat through one side and radiates heat to the other side. The thermoelectric element 162 is generally referred to as a Peltier element, and simultaneously performs heat absorption and heat dissipation by a supplied current. That is, the thermoelectric element 162 is composed of a semiconductor element that radiates heat absorbed through one side to the other side when current flows.

The cooling plate 164 is installed on one side of the thermoelectric element 162 and is cooled by the thermoelectric element 162. Accordingly, the air in contact with the cooling plate 164 is cooled by the cooling plate 164, and as a result, the temperature of the air is lowered below the dew point, and moisture is condensed on the cooling plate 164.

That is, the cooling plate 164 is disposed such that one side is in contact with the thermoelectric element 162 and the other side is in contact with the air flowing through the circulation flow path part 150. Accordingly, the air flowing along the circulation flow path 150 is cooled by the cooling plate 164 to condense moisture contained in the air.

Thereafter, the air cooled by the cooling plate 164 flows back into the flow path part 140 through the communication hole 142a.

The heat sink 166 is installed on the other side of the thermoelectric element 162 to release heat transferred from the thermoelectric element 162. On the other hand, the heat sink 166 may be formed to have a large area in order to improve the heat radiation efficiency.

In addition, the heat sink 166 is disposed adjacent to the flow path part 140 to discharge heat to the flow path part 140 side. Accordingly, the air whose temperature is increased by the heat sink 166 may be mixed with the air cooled through the cooling plate 164 and discharged through the discharge port 122.

Therefore, even if the air cleaner 100 is driven by the dehumidifying function of removing moisture from the air, it is possible to reduce the temperature rise of the air discharged to the discharge port 122.

The water tank 168 is mounted to the body housing 120 to be disposed under the cooling plate 164, and the water condensed on the cooling plate 164 is finally dropped into the water tank 168 and stored.

That is, the water tank 168 is disposed below the circulation flow path 150 so that the water condensed on the cooling plate 164 may be dropped and stored, and the water condensed water may be stored in the circulation flow path 150. The water discharge hole 156 may be provided to flow into.

Meanwhile, as illustrated in FIG. 3, the water tank 168 may be provided at a lower portion of the water discharge hole 156 and may include a concave groove 168a in which condensed water may be dropped and temporarily stored. An inlet hole 168b may be provided at the central portion of the concave groove 168. Accordingly, the condensed water contained in the concave groove 158 may flow into the water tank 168 through the inflow hole 168b to be stored.

On the other hand, the water tank 168 is installed in the body housing 120 so that the concave groove 168a is disposed in the water discharge hole 156 so that air flowing along the circulation flow path 150 flows out through the water discharge hole 156. It may not be. That is, the water discharge hole 156 is closed by the water tank 168 so that air flowing along the circulation flow path 150 may not flow out to the water discharge hole 156.

In addition, the concave groove 158 is formed to be inclined toward the center side, and the inflow hole 168b is disposed at the central portion of the concave groove 158 to close the inflow hole 168b by the condensed moisture temporarily stored in the concave groove 158. Outflow of air through can be prevented.

As described above, since water may be removed from the air circulating through the circulation air processing unit 160 installed in the circulation flow path unit 150, it is possible to minimize the decrease in the air volume.

That is, due to the pressure difference between the flow path part 140 and the circulation flow path part 150, air may be introduced into the circulation flow path part 150 to be re-introduced into the flow path part 140. Since it is possible to remove moisture from the air introduced into the air volume reduction by the circulation air processing unit 160 that performs the dehumidification function can be minimized.

In other words, the air purifier 100 according to the exemplary embodiment of the present invention is a circulation passage part 150 in comparison with an air purifier having a double passage consisting of a passage through which only purified air flows and a passage through which only dehumidified air flows. After removing the moisture from the air introduced into the) to flow back into the flow path 140 may reduce the flow rate loss by performing the dehumidification function.

In addition, since the air whose temperature is increased by the circulating air processing unit 160 that performs the dehumidifying function may flow along the circulation flow path unit 150 and may be mixed with the cooled air and discharged through the discharge port 122, the discharged air Can reduce the temperature rise.

On the other hand, the air purifier 100 according to an embodiment of the present invention is provided on one side of the circulation flow path unit 150 and the opening and closing unit for controlling the inflow or blocking of air from the flow path unit 140 to the circulation flow path unit 150 ( 170) may be further included.

1 and 2, the opening and closing unit 170 is installed at the circulating air inlet 152 side of the circulation passage 150 to open and close the opening and closing member 172 to open and close the circulating air inlet 152. The driving source 174 may be provided to rotate the opening / closing member 172.

That is, the opening degree of the circulating air inlet 152 is controlled by the opening / closing member 172, and accordingly, the flow amount of air introduced into the circulating air flow path part 150 may be adjusted. Thereby, the amount of dehumidification from air can be adjusted.

In other words, when the opening / closing member 172 fully opens the circulating air inlet 152, the flow amount of air flowing into the circulating air flow path part 150 increases, thereby increasing the amount of dehumidification from the air.

On the other hand, when the opening and closing member 172 is rotated to open only a part of the circulating air inlet 152, the flow amount of air flowing into the circulating air flow path unit 150 is reduced, thereby reducing the amount of dehumidification from the air.

The drive source 174 may be formed of a stepping motor to adjust the degree of rotation of the opening and closing member 172.

As a result, the air cleaner 100 according to an embodiment of the present invention may discharge the air from which moisture is removed from the air introduced into the air cleaner 100 through the opening and closing unit 170, without using a dehumidifying function. Only the air purified by the filter part can be discharged.

In addition, the amount of dehumidification from air can also be adjusted.

Hereinafter, with reference to the drawings will be described the operation of the air purifier according to an embodiment of the present invention.

4 and 5 is an operation diagram for explaining the operation of the air purifier according to an embodiment of the present invention.

In more detail, FIG. 4 illustrates that the air cleaner 100 operates only with an air cleaning function in which air flowing into the flow path part 140 is discharged through the discharge port 122 without directly entering the circulation flow path part 150. 5 is an operation diagram illustrating an operation of FIG. 5, in which air is introduced into the circulating flow path unit 150 and air from which moisture is removed by the circulating air processing unit 160 is mixed with air introduced into the flow path unit 140 to discharge the air outlet ( 122 is an operation diagram showing an operation of operating the air cleaner 100 by the dehumidification function discharged to the 122.

First, it will be described with reference to FIG. 4. When the circulating air inlet 152 is closed by the opening / closing unit 170 installed in the circulating air inlet 152, the air introduced into the flow path part 140 does not flow into the circulating flow path 150 but the flow path part 140. Air flowing along the flows while forming an arc and is discharged to the discharge port 122.

In this case, the air discharged through the discharge port 122 is air that has passed through only the filter unit (not shown).

On the other hand, since the air flowing into the flow path portion 140 can be discharged through the discharge port 122 without the air flowing into the circulation flow path unit 150, the amount of air discharged through the discharge port 122 is reduced Can be prevented.

Since the air cleaner 100 is operated while performing the dehumidifying function, as shown in FIG. 5, the circulating air inlet 152 is opened by the opening / closing unit 170. Accordingly, a part of the air flowing into the flow path part 140 to form a circular arc flows into the circulation flow path part 150 by the pressure difference between the flow path part 140 and the circulation flow path part 150.

The air introduced into the circulation flow path unit 150 flows along the circulation flow path unit 150 and passes through the circulation air processing unit 160. At this time, the air flowing along the circulation flow path 150 is in contact with the cooling plate 164 of the circulation air processing unit 160, and eventually the temperature of the air is lowered to remove moisture from the air.

Thereafter, the air from which moisture is removed is re-introduced into the flow path part 140 through the communication hole 142a and mixed with the air introduced into the flow path part 140 by the blower 130 to be discharged through the discharge hole 122. Can be.

As described above, some of the air discharged to the discharge port 122 is introduced into the circulation flow path unit 150 by the pressure difference between the flow path unit 140 and the circulation flow path unit 150, and the circulation flow path unit ( Since the air introduced into 150 may be re-introduced into the flow path part 140 to be discharged through the discharge hole 122, it is possible to minimize the decrease in the air volume of the discharge air discharged to the discharge hole 122.

In addition, since the air heated by the heat dissipation plate 166 of the circulating air processing unit 160 may flow along the circulating flow path 150 and may be mixed with the cooled air and discharged through the discharge port 122, the temperature of the discharged air The rise can be reduced.

Hereinafter, an air cleaner according to another embodiment of the present invention will be described with reference to the drawings. However, the same components as those described in the above embodiments will be replaced with the above description, and illustration and detailed description in the drawings will be omitted.

6 is a block diagram showing an air cleaner according to another embodiment of the present invention.

Referring to FIG. 6, the air cleaner 200 according to another embodiment of the present invention is, for example, a main body housing 220, a blower 230, a flow path part 240, a circulation flow path part 250, and circulating air. And a processing unit 260 and an opening and closing unit 270.

Meanwhile, the main body housing 220, the blower 230, the flow path 240, the circulation flow path 250, and the opening / closing part 270 are the main body housing 120 and the blower 130 described in the above embodiments. The configuration corresponding to the same components as the flow path part 140, the circulation flow path part 150, and the opening and closing part 170 will be omitted.

The circulating air processing unit 260 is installed in the mounting groove 254 provided in the circulating flow path unit 250, and may be configured as an additive discharging unit 262 for discharging the additive into air circulating by receiving the additive therein. .

The additive discharge unit 262 may include an additive receiving member 264.

The additive receiving member 264 may include an opening 264a to discharge the additive vaporized on one side, and the circulation passage part 250 and the additive receiving member by the air flowing through the circulation passage part 150. The additive may be discharged to the opening 264a by the difference in the internal pressure of the 264.
