Description

  The present invention relates to an air cleaning device with a ventilation function, and more specifically, a ventilation flow path and an air cleaning flow path are configured separately to enable optimum operation when performing ventilation operation and air cleaning operation, respectively. The present invention relates to an air cleaning device with a ventilation function.

  In general, an air purifier is a device that cleans air by filtering dust, bacteria, etc. in the air, but recently, by providing not only a basic air purifying function but also a ventilation function of room air. It is also possible to perform two functions with one device.

  As an apparatus capable of performing an air cleaning function and a ventilation function in this way, there is an air cleaner with a ventilation function disclosed in Patent Document 1. This air purifier includes an electric heat exchanger for performing heat exchange between air flowing into the room and air discharged outside the room, and two air blowers for supplying or exhausting the outdoor air and the room air. In the process of performing the air cleaning function and the ventilation function, a filter for filtering the air discharged into the room is provided in the main body. In addition, the air purifier includes a plurality of shutters that allow the internal flow path to be changed according to the selection of either the air cleaning operation or the ventilation operation.

  When such an air purifier performs a ventilation operation, the air supplied from the outside to the room is supplied to the indoor space sequentially through the intake side air blower, the electric heat exchanger, and the filter in the main body, and from the room to the outside. The discharged air is discharged to the outside through the exhaust side air blower and the electric heat exchanger sequentially. At this time, heat exchange is performed while the air flowing from the outside and the air discharged from the room pass through the electric heat exchanger. On the other hand, when the air purifier performs the cleaning operation, indoor air flows into the main body and then is supplied to the indoor space again through the two blowers and the filter. At this time, a part of the air passing through the intake-side air blower in the process of circulating inside the main body passes through the electric heat exchanger, and then merges with the air passing through the exhaust air-side blower, and the joined air passes through the filter and passes through the room. To be supplied.

  However, such a conventional air purifier has a structure in which air passes through a high-performance filter not only in the air cleaning operation but also in the ventilation operation. There is a drawback that the filter must be replaced frequently because it is shortened.

  In addition, the conventional air purifier has a structure in which the external air containing dust passes through the filter after passing through the electric heat exchanger during the ventilation operation, so that the heat exchange performance deteriorates due to the accumulation of dust on the electric heat exchanger. There was a problem.

  In addition, the conventional air purifier has a structure in which air from the outside passes through a high-performance filter during ventilation operation, and part of the air wastefully passes through the electric heat exchanger during air purification operation. There was a problem that air flow resistance increased and static pressure loss occurred, noise and vibration became intense, and energy loss was large.

In addition, the conventional air purifier is formed so that the indoor intake port and the indoor exhaust port are adjacent to each other on the same surface of the main body, so that it is discharged into the indoor space during the ventilation and air cleaning operations. There is a problem that the air cleaning and ventilation effect of the indoor air is reduced due to the phenomenon that the air that is reflowed to the inlet side.

An exhaust fan 33 formed of a centrifugal fan is installed in the upper exhaust space 31 at a corresponding position to blow air from the lower exhaust space 32 to the upper exhaust space 31. At this time, the exhaust fan motor 33 a is fixed to the inner upper surface of the main body 10. The third partition plate 14 that divides the air supply space 20 vertically is provided with a through hole 14a so that the air in the upper air supply space 21 flows to the lower air supply space 22, and a position corresponding to the through hole 14a. The lower air supply space 22 is provided with an air supply fan 23 that blows air from the upper air supply space 21 to the lower air space 22. At this time, the air supply fan 23 is also a centrifugal fan.

  As shown in FIGS. 2 and 4, the exhaust space 30 is defined inside the main body so that the air in the upper exhaust space 31 can be discharged to the outdoor discharge port 46 when performing the ventilation operation. An exhaust passage 34 and an air supply passage 24 defined inside the main body 10 along with the exhaust passage 34 so that the external air sucked from the outdoor suction port 45 can flow into the upper air supply space 21.

Thus, the ventilation filter 53 is installed. At this time, the air purifying filter 52 is composed of a high-performance filter that is stacked so as to filter foreign substances in the circulating indoor air and perform deodorization, and the ventilation filter 53 is a foreign substance such as dust contained in the external air. It consists of a medium performance filter that can be filtered.

  In addition, the air purifying apparatus according to the present invention is configured to open and close the second indoor suction port 42 so that the flow path in the main body 10 is switched when the user selects the air cleaning operation or the ventilation operation. 1 damper 61, a second damper 62 that simultaneously opens and closes the outdoor suction port 45 and the outdoor discharge port 46, and a third damper 63 that opens and closes the communication hole 47 of the first partition plate 12. These dampers 61, 62, and 63 are all configured such that an opening / closing member that operates by driving of a motor can rotate to open and close the flow path.

  Next, operation | movement of the air purifying apparatus which concerns on this invention of such a structure is demonstrated.

  When performing the ventilation operation, as shown in FIGS. 2 and 5, the first damper 61 of the second indoor suction port 42 and the second damper 62 of the outdoor suction port 45 and the outdoor discharge port 46 open the flow paths, respectively. The third damper 63 operates so as to close the communication hole 47 of the first partition plate 12. When the exhaust fan 33 and the air supply fan 23 operate in this state, the indoor air flows into the lower exhaust space 32 from the second indoor intake port 42 by the suction input of the exhaust fan 33, and passes through the exhaust fan 33 to enter the upper exhaust space. 31, and then passes through the electric heat exchanger 51 of the exhaust passage 34 and is then discharged to the outside through the outdoor outlet 46. Then, the outdoor outdoor air flows into the air supply passage 24 from the outdoor suction port 45 by the suction input of the air supply fan 23, and then flows into the upper air supply space 21 through the ventilation filter 53 and the electric heat exchanger 51 in turn. The air is supplied to the indoor space from the indoor outlet 43 through the air supply fan 23 and the lower air supply space 22. In addition, as shown in FIG. 4, when the second indoor outlet 44 of the lower air supply space 22 is provided so as to communicate with other indoor spaces through the flow path of the building wall, The two indoor spaces are ventilated while a part of the air in the side air supply space 22 is also supplied to other indoor spaces. At this time, for smooth ventilation of the other indoor spaces, the wall provided between the two indoor spaces is provided with the main body by the amount of air supplied from the second indoor discharge port 44 to the other indoor spaces. It is preferable that a communication flow path is provided so that air can flow to the indoor space side where 10 is installed.

  When performing such a ventilation operation, the present invention is such that the air exhausted to the outside through the exhaust passage 34 and the air supplied to the room through the air supply passage 24 cross the electric heat exchanger 51 while passing. Since mutual heat exchange is performed, heat loss in the indoor space can be minimized and ventilation can be performed. Further, as shown in FIG. 5, the air discharged from the indoor space to the outside flows into the lower exhaust space 32 from the opened second indoor suction port 42, and therefore does not pass through the air purification filter 52. That is, most of the air discharged to the outside is sucked from the second indoor suction port 42 having a low flow resistance, and therefore hardly passes through the air cleaning filter 52. As described above, the air purifying apparatus according to the present invention can extend the life of the air purifying filter 52 to the extent that the air discharged outside while performing the ventilation operation does not pass through the air purifying filter 52 unnecessarily. Since the flow resistance of the discharged air can be reduced, the ventilation operation is performed smoothly, and the flow noise and the vibration of the device are reduced.

  Further, according to the present invention, when the ventilation operation is performed, the external air flowing into the indoor space through the air supply passage 24 is filtered while passing through the ventilation filter 53 upstream of the electric heat exchanger 51. The problem that foreign matter such as dust accumulates can be prevented, whereby the heat exchange efficiency of the electric heat exchanger 51 can be increased accordingly, and the life of the electric heat exchanger 51 can be extended. Further, the present invention has a structure in which indoor air discharged to the outside is sucked from the second indoor suction port 42 on the lower surface of the main body 10 and external air is supplied to the indoor space from the indoor discharge port 43 on the side surface of the main body. Since the phenomenon that the air supplied into the room reflows into the second indoor suction port 42 can be minimized, the indoor space can be smoothly ventilated.

  When the air cleaning operation is performed, as shown in FIGS. 3 and 6, the first damper 61 of the second indoor suction port 42 and the second damper 62 of the outdoor suction port 45 and the outdoor discharge port 46 respectively pass through the flow paths. The third damper 63 operates so as to close, and the third damper 63 operates so as to open the communication hole 47 of the first partition plate 12. That is, at this time, the second indoor suction port 42, the outdoor suction port 45, and the outdoor discharge port 46 are closed, and the communication hole 47 of the first partition plate 12 is opened. When the exhaust fan 33 and the air supply fan 23 operate in this state, the indoor air flows into the lower exhaust space 32 from the first indoor suction port 41 and passes through the air cleaning filter 52, so that foreign matter is filtered and deodorization is eliminated. Done. The purified air flows into the upper exhaust space 31 through the exhaust fan 33 and then flows into the upper supply space 21 through the communication hole 47 of the first partition plate 12, and is supplied to the supply fan 23 and the lower supply space 22. Then, the air is further supplied from the indoor outlet 43 to the indoor space. At this time, since the outdoor suction port 45 and the outdoor discharge port 46 are closed by the second damper 62, air does not flow to the exhaust flow channel 34 and the air supply flow channel 24 side, and only indoor air is circulated. The indoor air is purified. Also at this time, when purified air is supplied from the second indoor outlet 44 to another indoor space as in the case of the ventilation operation described above, the air in the two indoor spaces can be simultaneously cleaned. it can.

  When performing such an air cleaning operation, the present invention is such that the circulating indoor air does not pass through the electric heat exchanger 51, so that the flow resistance is reduced and the air circulation becomes smoother. Reduces vibration. Further, when the air cleaning operation is performed, the exhaust fan 33 and the air supply fan 23 are both used for the circulation of room air, so that the air blowing capacity is increased. Therefore, smooth air is sent while circulating air passes through the high-performance air purifying filter 52 having a large flow resistance.

  Further, according to the present invention, when the air cleaning operation is performed, the air sucked into the main body 10 is sucked into the first indoor suction port 41 on the lower surface of the main body, and the purified air is discharged into the indoor space on the side surface 11 of the main body 10. Since the structure is such that the air is discharged from the outlet 43 to the indoor space, the phenomenon that the air supplied into the room reflows into the first indoor suction port 41 can be minimized, so that the air cleaning operation of the indoor space can be performed smoothly. Can do.
