[0022] The present invention will be described in detail below with reference to the attached drawings.

[0023] FIG. 1 is an exploded perspective view of a ventilation-type air purifier with solar power generation according to the present invention.

[0024] The ventilation type air purifier (100) is installed in the gap formed between the window sash and the window frame. After fixing the middle plate (171) to the window frame, the front cover (172) is attached to the front of the middle plate (171) and the rear cover (120) is attached to the rear to complete the installation.

[0025] An intake fan bracket (130) is attached to the upper part of the inner side of the rear cover (120), an exhaust fan bracket (140) is attached to the lower part, and a filter unit (160) is attached to the middle part and mounted.

[0026] Figure 3 shows the structure of the intake fan bracket in detail.

[0027] An intake fan (132) is housed inside the intake fan bracket (130), a junction unit (210) is mounted in the area (133) between the intake fans (132), a battery (230) is fitted and mounted in the area (131) outside each intake fan (132), a fan cover (134) is attached to the inside of the intake fan bracket (130) to cover them, and an adapter unit (220) is installed on the outer corner of the intake fan bracket (130).

[0028] Additionally, an exhaust fan (142) and a valve unit (144) are housed on one side of the exhaust fan bracket (140), and a control unit (240) and a cover (241) are installed on the opposite side of the exhaust fan bracket (140).

[0029] The valve unit (144) is opened by the flow of air discharged by the exhaust fan (142), and is closed by the restoring force of the spring when there is no flow of discharged air.

[0030] As described above, the intake fan (132), exhaust fan (142), valve unit (144), adapter unit (220), junction unit (210), control unit (241), and battery (230) are housed and mounted in the intake fan bracket (130) and exhaust fan bracket (140), respectively. By housing the intake fan bracket (130) and exhaust fan bracket (140) in the upper and lower regions of the rear cover (120), respectively, a compact structure can be maintained.

[0031] An external air intake slot is formed in the middle area of ​​the rear cover (130), and a filter unit (160) is formed and mounted by sequentially stacking a pre-filter (161), a composite filter (162), and a filter cover (164) in this area.

[0032] As is well known, the composite filter (162) can be composed of a HEPA (High Efficiency Particulate Air) filter that filters fine dust, a filter that removes harmful gases, and a filter that filters bacteria and germs.

[0033] A solar panel (110) is mounted on the outer side of the rear cover (120), and power converted from the solar panel (110) is supplied to the power supply through a supply plug (112).

[0034] Since the solar panel (110) is exposed to the outside, the supply plug (112) can be connected to the junction unit (210) through a waterproof connector (not shown) installed on the rear cover (120), as described later, so that the power connection path can be kept waterproof.

[0035] The shutter assembly (150) is installed between the filter unit (160) and the intake fan bracket (130) and serves to allow or block filtered outside air from being sucked in by the intake fan (132).

[0036] Figures 4(a) and 4(b) each show the adapter unit in detail.

[0037] The adapter unit (220) comprises a PCB (221), a USB connector (223) protruding from the front of the PCB (221), and an output connector (222) protruding from the rear of the PCB (221).

[0038] The USB connector (223) may be, for example, a USB-C type, and a 12V adapter and a sensing sensor for measuring air quality are connected in common to receive power from the 12V adapter and transmit and receive electrical signals to and from the sensing sensor.

[0039] The output connector (222) transmits power and electrical signals received from the USB connector (223) to the junction unit (210) through a cable via a conductive pattern formed on the PCB (221).

[0040] Figures 5(a) and 5(b) each show a junction unit.

[0041] The junction unit (210) is equipped with a solar jack (213) into which solar power is input, an input connector (212) connected to an output connector (222) of an adapter unit (220), a relay connector (214) connected to a control unit (240), and a battery jack (215) electrically connected to a battery (230).

[0042] Additionally, the junction unit (210) is equipped with an electronic switch (218) that selects one of the adapter power output from the input connector (212), the solar power output from the solar jack (213), and the battery power output from the battery jack (215) to supply as the operating power for the device.

[0043] Preferably, the electronic switch unit (218) has as its standard for power supply sequentially supplying solar power from a solar panel (110), battery power from a battery (230), and adapter power from an adapter (180) that supplies commercial power.

[0044] By supplying power in this manner and reducing commercial power consumption as much as possible, it is possible to respond to the zero energy consumption goal of carbon neutrality policies.

[0045] Figure 6 shows a configuration for supplying power to operate the device.

[0046] First and second voltage measuring sensors (111, 231) are installed on the output sides of the solar jack (213) to which solar power is supplied and the battery jack (215) to which battery power is supplied, respectively, and a current measuring sensor (181) is installed on the output side of the input connector (212) to which adapter power is supplied.

[0047] Based on the supply sequence of the device operation power, the electronic switch unit (218) preferentially supplies solar power as the device operation power.

[0048] To this end, if the voltage of the solar power measured by the first voltage measuring sensor (111) is greater than or equal to the reference voltage, the electronic switch unit (218) supplies the solar power as the operating power for the device.

[0049] On the other hand, if the voltage of the solar power measured by the first voltage measuring sensor (111) is less than the reference voltage and the voltage of the battery power measured by the second voltage measuring sensor (231) is greater than or equal to the reference voltage, the electronic switch unit (218) supplies the battery power as the operating power for the device, and if the voltage of the battery power measured by the second voltage measuring sensor (231) is less than the reference voltage, the electronic switch unit (218) supplies the adapter power as the operating power for the device.

[0050] Preferably, the electronic switch unit (218) measures the current of the power supplied to the device using a current measuring sensor (217), measures the current of the power supplied from the adapter (180), calculates the ratio of the adapter power to the power supplied to the device, and transmits it to a cloud server via communication.

[0051] As a result, the efficiency of the solar panel (110) can be analyzed by calculating the amount of power from the adapter used for operating the device.

[0052] Figure 7 shows the battery charging configuration.

[0053] The charging control unit (219) determines that the battery (230) needs to be charged when the battery voltage measured by the voltage measurement sensor (231) is less than or equal to the charging reference voltage.

[0054] The charging source is pre-set in the order of solar power -> adapter power, and the charging control unit (219) charges the battery (230) using solar power supplied from the solar panel (110) when the voltage measured by the voltage measurement sensor (111) is greater than or equal to the reference voltage.

[0055] On the other hand, if the voltage measured by the voltage measuring sensor (111) is less than the reference voltage, the charging control unit (219) charges the battery (230) using the 12V adapter power supplied from the adapter (180).

[0056] In this way, the utility of the solar panel (110) can be increased by primarily charging the battery (230) using solar power.

[0057] The operation of the ventilation-type air purifier is described below.

[0058] When the power button is pressed and the ventilation-type air purifier starts operating, the shutter assembly (150) opens according to the instructions of the control unit (240) and the intake fan (132) rotates to draw in outside air.

[0059] As described above, the supplied power is supplied in the order of solar power from the solar panel (110) by the electronic switch unit (218), and if the solar power does not reach the reference voltage, battery power from the battery (230) and adapter power from the adapter (180) that supplies commercial power.

[0060] Outside air introduced through the outside air inlet slot formed in the rear cover (120) is filtered while passing through the filter unit (160), and flows upward from the filter unit (160), passes through the shutter assembly (150), passes through the intake fan (132), and enters the interior.

[0061] When indoor air is discharged, the exhaust fan (142) rotates by the control unit (240), and the valve unit (144) opens according to the flow of the discharged air, so that the indoor air is discharged to the outside.

[0062] Although the present invention has been described above with reference to embodiments, it is understood that various modifications can be made by those skilled in the art. Accordingly, the scope of the present invention should not be interpreted as being limited to the above-described embodiments, but should be interpreted by the claims set forth below.
