In general homes, offices, and other rooms in which the cooling/heating apparatus is installed, the rooms are maintained in a closed state to improve cooling/heating efficiency, and since the degree of air pollution increases when a predetermined time passes through the closed indoor space, foreign substances such as bad smell and floating dust may be generated in the rooms. Therefore, in order to remove such bad smell, dust, or the like from the indoor, indoor air is ventilated at predetermined time intervals, and at this time, a ventilation device for supplying fresh outdoor air to the indoor while maintaining the indoor temperature and discharging polluted indoor air to the outdoor is used.
If the ventilator is used for a predetermined time or more, foreign substances such as dust are accumulated in a filter provided in the ventilator, and thus it is necessary to periodically clean and replace the filter.
As an example, a pre-Filter for filtering large dust having a large particle size needs to be cleaned more than once between 1 month and 2 months, and a high efficiency particulate air Filter (HEPA Filter) for filtering fine dust having a small particle size needs to be replaced between 6 months and 1 year, so that the function of the Filter can be maintained normally.
As described above, since the inspection time for cleaning and replacing the filter is different according to the kind of the filter, there is inconvenience of cleaning or replacing the filter for at least 2 months or more, in the case where the filter is left without cleaning in time, the life of the filter becomes short to increase the replacement cost of the filter, and in the case where the filter is manually cleaned, there is inconvenience that the ventilation device cannot be used during the cleaning work.
Further, in the case where the ventilator is connected to a duct of a ceiling and the filter is installed inside the main body of the ventilator, it is difficult for an operator to access the inside of the main body of the ventilator when replacing the filter, and since it is necessary to disassemble the peripheral devices installed inside the main body of the ventilator to replace the filter, the replacement work of the filter is not easy, and there is a problem that a lot of time is consumed. The prior art related to the cleaning of the filter of the ventilating device is disclosed in korean patent laid-open publication No. 10-0563524, korean patent laid-open publication No. 10-0894362, etc.

However, the first and second connection pipes 310 and 320 may be omitted, the second air supply port 212 and the outdoor air inflow port 131 may be directly installed, and the first air discharge port 221 and the indoor air discharge port 121 may be directly installed.
Hereinafter, the operation of the ventilation mode, the air cleaning mode, and the filter cleaning mode of the ventilation device 1 according to the present invention configured as described above will be described with reference to fig. 3 to 5.
Referring to fig. 3, in the ventilation mode, the air supply damper 132 and the second damper 213 are opened, the first damper 223 is operated to close the communication port 202 and open the second exhaust port 222, and the exhaust fan 122 and the air supply fan 142 are driven.
In the ventilation mode, as indicated by arrows in fig. 3, the indoor air passes through the indoor air inflow port 111, the first exhaust chamber 110, the total heat exchanger 150, the second exhaust chamber 120, and the indoor air discharge port 121 of the main body 100, and then passes through the first exhaust port 221, the exhaust chamber 220, and the second exhaust port 222 of the filter cassette 200 via the second connection duct 320 to be discharged to the outdoor side. Meanwhile, the outdoor air is filtered through the first air supply port 211, the first filter 230, the air supply chamber 210, the second filter 240, and the second air supply port 212 of the filter cassette 200, and then supplied to the indoor side through the outdoor air inflow port 131, the first air supply chamber 130, the total heat exchanger 150, the second air supply chamber 140, and the outdoor air discharge port 141 of the main body 100 via the first connection duct 310.
According to this configuration, in the ventilation mode, the outdoor air passes through the first filter 230 to filter foreign substances of relatively large particles, and the micro-sized foreign substances that are not filtered by the first filter 230 pass through the second filter 240 to be filtered, thereby supplying the purified outdoor air to the indoor side. Since the indoor air and the outdoor air exchange heat while passing through the total enthalpy heat exchanger 150, the outdoor air is supplied to the indoor side in a state of receiving heat of the indoor air and increasing in temperature, and thus fresh outdoor air can be supplied to the indoor while maintaining the indoor temperature, and contaminated indoor air can be discharged to the outdoor.
Referring to fig. 4, in the air cleaning mode, the air supply damper 132 is opened, the first damper 223 is operated to open the communication port 202 and close the second exhaust port 222, the second damper 213 is closed, and the exhaust fan 122 and the air supply fan 142 are driven.
In the air cleaning mode, as shown by arrows in fig. 4, the indoor air flowing into the first air discharge chamber 110 through the indoor air inlet 111 of the main body 100 passes through the total heat exchanger 150, the second air discharge chamber 120, and the indoor air discharge outlet 121, passes through the first air discharge port 221, the air discharge chamber 220, the communication port 202, the air supply chamber 210, the second filter 240, and the second air supply port 212 of the filter cassette 200 through the second connection duct 320, passes through the outdoor air inlet 131, the first air supply chamber 130, the total heat exchanger 150, the second air supply chamber 140, and the outdoor air discharge outlet 141 of the main body 100 through the first connection duct 212, and is supplied into the room.
According to this configuration, in the air cleaning mode, the flow path of the indoor air is formed such that the air sucked from the indoor is circulated only through the second filter 240 without passing through the first filter 230, so that the pressure loss of the circulated indoor air can be reduced, and the indoor air can be smoothly flowed to improve the air cleaning function.
Referring to fig. 5, in the filter cleaning mode, the air supply damper 132 is closed, the first damper 223 is operated to open the communication port 202 and close the second exhaust port 222, and the second damper 213 is opened, so that the exhaust fan 122 is driven.
In the filter cleaning mode, as shown by arrows in fig. 5, the indoor air having flowed into the first air discharge chamber 110 through the indoor air inlet 111 of the main body 100 passes through the total heat exchanger 150, the second air discharge chamber 120, and the indoor air discharge port 121, and then passes through the first air discharge port 221, the air discharge chamber 220, the communication port 202, the air supply chamber 210, the first filter 230, and the first air supply port 211 of the filter cassette 200 through the second connection duct 320 to be discharged to the outside.
According to this configuration, in the filter cleaning mode, the air exhaust flow path is formed such that the indoor air passes through the first filter 230 that can regenerate and is discharged to the outside, so that foreign substances such as dust trapped in the first filter 230 are separated from the first filter 230 by the flow force of the air and are discharged to the outside of the room, and cleaning of the first filter 230 is automatically performed by such reverse cleaning, whereby the cycle of manually cleaning the first filter 230 can be matched with the replacement cycle of the second filter 240, and the convenience of the work of cleaning the first filter 230 can be improved and the life of the first filter 230 can be extended.
In the filter cleaning mode, the exhaust flow path of the air is formed such that the indoor air does not pass through the non-regenerative second filter 240 having a high static pressure loss, thereby reducing the power consumption of the exhaust fan 122, increasing the air volume and the static pressure, and improving the cleaning efficiency of the first filter 230.
As described above, the present invention is not limited to the above-described embodiments, and a person having ordinary knowledge in the art to which the present invention belongs can perform an obvious modified implementation without departing from the technical idea of the present invention claimed in the claims, and such modified implementation is within the scope of the present invention.
