The present invention relates to an air purifier having a room temperature control function, and more particularly, by suctioning air from outside and filtering it, the filtered air can be cooled by a regenerative evaporation method, and exhaust of moisture generated during cooling. The present invention relates to an air cleaner that can change a direction to a direction desired by a user.

The air in the room is all the airflow generated from the opening and closing of the door, the movement of the occupants, and the ventilation through the window.In winter or in bad weather, the air is not ventilated through the window. Such stagnant air causes respiratory diseases, allergic skin diseases, headaches, and the like, which causes very unpleasant and harmful effects on the human body.

Therefore, in general, the circulation of air is indispensable in the dwelling or work space where people live, and all buildings have a ventilation system that is designed and installed by a prescribed law such as a building law. It can be divided into circulation type and forced circulation type and almost all houses such as public buildings, multi-unit houses and single-family houses are merged and installed.

Natural circulation is limited in the total amount of air circulation because the ventilation of the indoor air is not enough, the forced circulation ventilation system, that is, the air cleaner is configured to increase the amount of circulation of the air mechanically.

Hereinafter, a conventional air cleaner will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing the internal configuration of a conventional air cleaner.

As shown in FIG. 1, a conventional air cleaner includes a casing 10 having an inlet 12 and an outlet 14, and foreign substances and harmful substances contained in air introduced from the outside by being coupled to the inlet 12. It comprises a filter net for removing gas and the like 20 and the filtration filter 30, and a blower for introducing the outside air through the suction port 12 and discharged to the discharge port (14).

The sieve 20 serves to firstly remove foreign substances, such as hair or fibrous dust, that are somewhat large among foreign substances present in the air introduced from the outside, and the filtration filter 30 is firstly removed by the sieve 20. It plays a role in removing fine foreign matter such as micro dust and mites in the air. In this case, a carbon filter (not shown) for removing various odors, harmful gases, nicotine, and the like in the air may be further provided.

However, since the conventional air cleaner having the above structure only has a function of filtering air, it cannot cool the air or control the humidity, so that the user can adjust the air conditioner and the room humidity to lower the temperature of the air. The inconvenience of having to prepare a separate humidifier.

As described above, in addition to the air cleaner, there is a problem in that it is expensive to provide a separate air conditioner and a humidifier, and energy consumption is increased to operate each device.

In addition, when using a general air conditioner using a refrigerant for cooling the energy consumption is a lot, in order to solve this problem in recent years has been proposed various types of evaporative air conditioner using the latent heat of water. The evaporative air conditioner is divided into two types: the direct evaporative air conditioner and the regenerative evaporative air conditioner. The direct evaporative air conditioner introduces all moisture generated by evaporation of water into the room. There is a disadvantage, and the regenerative evaporative air conditioner exhausts all moisture generated by water evaporation to the outside, so that the indoor humidity does not increase excessively, but indoor humidification is performed by using the moisture generated when the room is dry. The disadvantage is that it can't be.

In addition, the evaporative air conditioner uses the latent heat of evaporation of water, and thus the cooling ability varies depending on various conditions such as the ambient temperature and humidity. There is a problem that becomes large.

It comprises a filtration filter 220 for removing fine foreign matter such as fine dust and mites. In this case, the filtration filter 220 for filtering fine dust in the air is similar in structure and function to the filtration filter 220 applied to a conventional air cleaner, and thus a detailed description thereof will be omitted.

In addition, the dehumidifying means 300 is manufactured to include a zeolite that absorbs moisture in the air, and serves to remove moisture in the air passing through the filtering means 200. In this case, the dehumidifying means 300 may be manufactured to include one or more of various materials having dehumidifying power such as activated carbon, diatomaceous earth, silica gel, starch, bentonite, and alumina in addition to zeolite. In this embodiment, the zeolite has an effect of about 20 times superior to other materials in repetitive regeneration ability and moisture absorption rate, and is included in the dehumidification means 300. And if necessary, by installing titanium oxide or a glass filter on both sides of the dehumidifying means 300 can have both the dust collection capacity and the deodorizing ability.

In addition, the dehumidifying means 300 applied to the present invention, as well as the filter structure shown in this embodiment can be changed to various kinds of dehumidifying members and devices.

As shown in FIGS. 4 and 5, the cooling means 400 applied to the air cleaner according to the present invention includes air introduced into the casing 100 by the blower 140 and discharged toward the outlet 120. The wet channel through which the main flow air a1 passes through the gun channel 422 through which the main flow air a1 passes, and is separated from the gun channel 422 by the diaphragm 426. 424 and a water supply unit 410 for supplying water (w) into the wet channel (424).

Water (w) supplied into the wet channel (424) is evaporated by the air passing through the wet channel (424), so that the temperature inside the wet channel (424) is lowered by the latent heat of evaporated water (w) The air inside the gun channel 422 in contact with the wet channel 424 is also cooled and discharged through the outlet 120.

The dry channel 422 and the wet channel 424 are alternately arranged in parallel so as to be in contact with each other so that heat exchange can occur more effectively, and increase the heat transfer rate inside the dry channel 422 and the wet channel 424. In order to achieve this, a dry channel cooling fin 423 and a wet channel cooling fin 425 made of a material having a high heat transfer rate such as aluminum are provided.

The dry channel cooling fin 423 and the wet channel cooling fin 425 are formed in a plate shape bent several times, and the longitudinal direction thereof is disposed in parallel with the flow direction of the air so as not to interfere with the flow of the air. At this time, the water supply unit 410 for supplying water (w) to the wet channel 424, the water supply is provided on the upper side of the wet channel 424 to distribute the water (w) evenly to each wet channel cooling fin 425. Water (W) is injected through the pipe 412 toward the broad surface of the wet channel cooling fin 425, that is, the direction perpendicular to the flow of air. In addition, the wet channel cooling fin 425 has a plurality of penetrating in the thickness direction so that the water (w) can be evenly distributed in the lower portion as well as the upper portion where the water (w) is directly injected from the water supply pipe (412). A water hole h is formed. As such, when the water hole h is formed in the wet channel cooling fin 425, the water w may be delivered to all parts, and the water w injected from the water supply pipe 412 may not be directly contacted. Water (w) can be distributed even to the bottom surface, it is possible to obtain a more active evaporation effect.

As the air flowing into the wet channel 424 is dried, the water (w) evaporation effect in the wet channel 424 is increased and the cooling performance is improved accordingly. The air cleaner according to the present invention has a dehumidifying means 300. After dehumidifying the air introduced into the casing 100 by using to deliver to the cooling means 400, there is an advantage that the cooling performance is further improved. In addition, even when the amount of air introduced into the wet channel 424 increases, the water (w) evaporation effect of the inside of the wet channel 424 is increased, and thus the cooling performance is also improved. Since the exhaust fan 600 is provided between the outlet of the wet channel 424 and the exhaust port 130 (see FIG. 3), the cooling capacity is further increased compared to the conventional evaporative air conditioner in which air flows only by the blower 140. It has the advantage of being better.

In addition, when the cooling air (a2) cooled by the evaporation of the water (w) is introduced into the room, the evaporation pad 430 directly around the outlet 120 to further lower the temperature of the cooling air (a2) ) May be provided. Since the direct evaporative pad 430 is a member that is commonly used in the direct evaporative cooling device, a detailed description thereof will be omitted. In this case, when the direct evaporation pad 430 is used, since the humidity of the air flowing into the room is increased, when the humidity of the indoor air is not desired to be increased, the direct evaporation pad 430 may be removed.

The operation of the cooling means 400 is as follows.

Cooling means 400 according to the present invention is configured to block the wet channel 424 by the additional air passage 421 when viewed from the air inlet side, it is transmitted to the cooling means 400 through the blower 140 The main flow air a1 flows only through the gun channel 422, and a part of the main flow air a1 that passes through the gun channel 422 enters the wet channel 424 to allow the main flow air a1 to flow. Flow in the opposite direction, the remaining main flow air (a1) is supplied to the room through the outlet 120.

Water (w) is supplied to the wet channel 424 by the water supply part 410, and the water (w) is lowered through the water hole h processed in the wet channel cooling fin 425. As it flows down, it evenly wets the cooling fin surface of the wet channel 424. On the surface of the wet channel cooling fin 425 moistened with water (w), the water (w) is evaporated by a part of the main flow air (a1) flowing into the wet channel (424), that is, the bleed air (a3). Due to latent heat of evaporation, the temperature of the wet channel cooling fin 425 is lowered, and heat transfer occurs from the dry channel 422 to the wet channel 424 due to the temperature difference between the dry channel 422 and the wet channel 424.

The heat transferred from the dry channel 422 to the wet channel cooling fins 425 maintains the temperature of the wet channel cooling fins 425 relatively higher than the temperature of the additional air (a3), thereby providing the wet channel cooling fins 425. This makes the water (w) evaporation from the surface more vigorous. The additional air a3 passing through the wet channel 424 is an exhaust port 130 (see FIG. 3) formed in the casing 100 through the additional air hole 428 of the additional air passage 421 and the upper plate 427. Exhausted.

The upper and lower portions of the gun channel 422 are blocked by the upper plate 427 and the lower plate 429, respectively, so that the water (w) supplied from the water supply unit 410 does not flow into the dry channel 422 and the wet channel. Supplied only at 424. A bucket 414 is provided at the bottom of the wet channel 424, and the remaining water w of the water w supplied to the wet channel 424 without being evaporated is collected again into the bucket 414, and the bucket 414 is provided. The collected water w is supplied back to the wet channel 424 by the pump 416 and the feed pipe 412.

As described above, the cooling means 400 applied to the present invention is that the additional air (a3) passing through the wet channel 424 to which water (w) is injected is not directly introduced into the room but is cooled by the wet channel 424. Since the cooling air (a2) passing through the channel 422 is introduced into the room, the humidity of the room does not increase even if used for a long time, and the water (w) evaporation amount is significantly smaller than that of the direct evaporative cooler, so that the water supply part 410 inside The advantage is that there is no need to continuously supply water (w).

Since the air cleaner according to the present invention is configured to dehumidify air introduced into the cooling means 400 using the dehumidifying means 300, the water (w) evaporation efficiency in the wet channel 424 is improved, and Therefore, it is possible to discharge the air at a lower temperature than the general regenerative cooler.

When using the latent heat of water, such as the cooling means 400 applied to the present invention, since the evaporation amount of water depends on the ambient temperature and humidity, the minimum temperature and cooling of the cooling air (a2) discharged through the outlet 120 according to the ambient temperature and humidity Force is determined.

Therefore, the air purifier according to the present invention includes a temperature and humidity detection sensor 152 for detecting a current temperature and humidity, and a display unit 154 for outputting a current cooling force by receiving a signal from the temperature and humidity detection sensor 152. The cooling force display means 150 further includes (see FIG. 2).

In this case, the cooling force display means 150 is provided with a plurality of operation buttons 156 for signal input so that the user can operate each unit under a desired condition. In addition, the display unit 154 is preferably configured to display various values related to cooling power, such as the minimum temperature and air flow rate of the air discharged through the current outlet 120.

Therefore, the user can see the numerical values appearing on the display unit 154, and it is possible to know how much cooling power the present air purifier according to the present invention can produce.

6 is a cross-sectional view showing an example of use of the air cleaner according to the present invention.

As shown in FIG. 6, the exhaust pipe 500 applied to the present invention is for guiding the exhaust direction of the humidified air while passing through the wet channel 424. The exhaust pipe 500 is formed in a corrugated pipe shape so that the user wants the humidified air. Can be exhausted in the direction.

Therefore, when the indoor humidity is sufficiently high, the outlet of the exhaust pipe 500 is placed outdoors so that the indoor humidity is not increased any more, and when the indoor humidity is low, the outlet of the exhaust pipe 500 is placed indoors. Air purifier by means of the role of the humidifier.

Thus, the air purifier according to the present invention has the advantage of cooling the air and the function of humidifying the room in addition to the basic function of purifying the air, there is an advantage that does not need to provide a separate cooler and humidifier.

In addition, the exhaust pipe 500 applied to the present invention is not limited to the corrugated pipe shape as shown in the embodiment shown in Figure 6, it may be made of a flexible material such as rubber or various synthetic resins.
