[0067] The second cover (128) can be moved to open the opening (127), and with the second cover (128) opening the opening (127), the user can pull and separate the heating element (170), the filter (175, 176, 177), or the dust bin (195).

[0068] The above ventilation device (10) may include a main body (150) composed of main parts for the operation of the ventilation device (10).

[0069] The main body (150) may include a plurality of fan modules (161, 162) that generate air flow. The plurality of fan modules (161, 162) may include a first fan module (161) that sucks in indoor air and exhausts it outdoors, and a second fan module (162) that sucks in outdoor air and supplies it indoors. The first and second fan modules (161, 162) may each include a fan and a motor that rotates the fan.

[0070] The first fan module (161) may be arranged adjacent to the inner side of the second flange (160). The second fan module (162) may be arranged adjacent to the inner side of the fourth flange (165).

[0071] The above main body (150) may include a heating element (170). The heating element (170) is configured so that a first flow path of outdoor air and a second flow path of indoor air exchange heat with each other, and the first flow path and the second flow path may each be provided in multiple numbers and arranged to be stacked on top of each other.

[0072] The air flow flowing through the plurality of first flow paths and the air flow flowing through the plurality of second flow paths can be formed in directions that intersect each other (see arrows in Fig. 4).

[0073] The above heating element (170) has a roughly hexahedral shape, and among the multiple side surfaces of the heating element (170), the first and second side surfaces facing each other form an inlet surface and an outlet surface for outdoor air, respectively, and the third and fourth side surfaces facing each other can form an inlet surface and an outlet surface for indoor air, respectively.

[0074] The above heating element (170) can be placed approximately in the center of the internal space of the housing (100).

[0075] The main body (150) may include a plurality of filters (175, 176, 177). The plurality of filters (175, 176, 177) may include a first filter (175) arranged in an outdoor air flow path. The first filter (175) is arranged on the inside of a third flange (240) forming an outdoor air intake portion and may be arranged on the inlet side of the heat transfer element (170). Therefore, the outdoor air sucked through the third flange (240) may pass through the first filter (175) and flow into the first flow path of the heat transfer element (170).

[0076] The above-described plurality of filters (175, 176, 177) may include a second filter (176) arranged in a flow path of indoor air. The second filter (176) is arranged on the inside of the first flange (230) forming an intake portion of indoor air and may be arranged on the inlet side of the heating element (170). Accordingly, indoor air drawn in through the first flange (230) may pass through the second filter (176) and flow into the second flow path of the heating element (170).

[0077] The first filter (175) may be positioned so as to face the first side forming the outdoor air inlet surface of the heating element (170). The second filter (176) may be positioned so as to face the third side forming the indoor air inlet surface.

[0078] The above first filter (175) and second filter (176) can constitute a “pre-filter”.

[0079] The above-described plurality of filters (175, 176, 177) may include a third filter (177) arranged in the outdoor air path. The third filter (177) may be arranged on the discharge side of the first filter (175) and the inlet side of the heat transfer element (170). Accordingly, the outdoor air sucked through the third flange (240) may sequentially pass through the first filter (175) and the third filter (177) and flow into the first path of the heat transfer element (170).

[0080] For example, the third filter (177) may constitute a “HEPA filter.”

[0081] The above main body (150) may include a PCB device (180) including a control component for the operation of the ventilation device (10). For example, the PCB device (180) may be placed in a space between the first and second fan modules (161, 162) and mounted on a PCB bracket (182).

[0082] The above main body (150) may include a bypass blocking plate (185) to block the sucked outdoor air from being bypassed to the indoor air path side or to block the sucked indoor air from being bypassed to the outdoor air path side.

[0083] The above bypass blocking plate (185) may include a first blocking plate (185a) placed between the intake side of indoor air and the second fan module (162) and a second blocking plate (185b) placed between the intake side of outdoor air and the first fan module (161).

[0084] The first blocking plate (185a) may be placed in the space between the first flange (230) and the fourth flange (165), and the second blocking plate (185b) may be placed in the space between the third flange (240) and the second flange (160).

[0085] By means of the first blocking plate (185a), indoor air sucked in from the first flange (230) can be prevented from bypassing the heating element (170) and flowing toward the second fan module (162).

[0086] However, the first blocking plate (185a) may include an openable flap. When the flap is opened, indoor air sucked in from the first flange (230) may bypass the heating element (170) and be supplied to the indoor space through the second fan module (162) and the fourth flange (165).

[0087] By means of the second blocking plate (185b), the outdoor air sucked in from the third flange (240) can be prevented from bypassing the heating element (170) and flowing toward the first fan module (161).

[0088] The main body (150) may include a filter cleaning device (190) provided on one side of the first filter (175) and configured to clean foreign substances captured in the first filter (175). The filter cleaning device (190) may be configured to clean foreign substances filtered in the first filter (175) from air sucked in from outdoors.

[0089] The filter cleaning device (190) may include a filter driving motor for moving the first filter (175), a brush for scraping the surface of the first filter (175), and a suction motor for moving foreign substances separated from the first filter (175) to a dust bin (195). The dust bin (195) stores foreign substances separated from the first filter (175) and may be provided on the inlet side of the suction motor.

[0090] The above ventilation device (10) may include a duct connecting device (200) that constitutes the first flange (230) and the third flange (240) and is connected to a duct. For example, the duct connecting device (200) may include a first connecting device (200a) that constitutes the first flange (230) and a second connecting device (200b) that constitutes the third flange (240).

[0091] The first connecting device (200a) may be provided on the first edge side of the ventilation device (10), and the second connecting device (200b) may be provided on the second edge side. The first and second connecting devices (200a, 200b) may be arranged to face each other.

[0092] The above duct connecting device (200) can be mounted on the bottom surface (121) of the second housing (120). The bottom surface (121) can include a mounting portion (121a) that supports the duct connecting device (200). The mounting portions (121a) are provided in multiple numbers, and the first connecting device (200a) and the second connecting device (200b) can be mounted on each mounting portion (121a).

[0093] The above duct connecting device (200) can be coupled to the first housing (110) and the second housing (120). For example, when the first and second housings (110, 120) are coupled, a mounting groove in which the duct connecting device (200) is positioned can be formed on the corner side of the first and second housings (110, 120).

[0094] In detail, a first groove (115) that is in contact with a corner of the duct connecting device (200) may be formed on a corner side where a plurality of side portions of the first housing (110) meet. A second groove (125) that is in contact with a corner of the duct connecting device (200) may be formed on a corner side where a plurality of side portions of the second housing (120) meet.

[0095] The first home portion (115) may be formed in multiple numbers at the first corner and the second corner of the first housing (110) so that the first and second connecting devices (200a, 200b) are respectively mounted thereon.

[0096] The second home portion (125) may be formed in multiple numbers at the first and second corners of the second housing (120) so that the first and second connecting devices (200a, 200b) are respectively mounted thereon.

[0097] When the first housing (110) and the second housing (120) are combined, a mounting groove in which the first and second connecting devices (200a, 200b) are positioned can be defined by the first groove (115) and the second groove (125).

[0098] The first connecting device (200a) may include a first plate (210) and a second plate (220) bent from the first plate (210). The first and second plates (210, 220) may have a flat plate shape having a predetermined height.

[0099] The first plate (210) may constitute a portion of one of the multiple side portions (113) of the housing (100). The second plate (220) may constitute a portion of another of the multiple side portions (113).

[0100] The first connecting device (200a) may include a first flange (230) provided on the first plate (210). The first flange (230) may be configured to protrude from the first plate (210).

[0101] For example, the first flange (230) may be configured to protrude from the first side of the housing (100) at the first mounting position of the first connecting device (200a) (see FIG. 5). In addition, the first flange (230) may protrude in the X direction with reference to FIG. 1.

[0102] In the first mounting position, the first end portions of the first plate (210) and the second plate (220) can be mounted on the mounting portion (121a) of the second housing (120). The first end portion can be defined as the lower end.

[0103] Conversely, in the second mounting position of the first connecting device (200a), the first flange (230) may be configured to protrude from the second side of the housing (100) (see FIG. 9). In addition, the first flange (230) may protrude in the Y direction with reference to FIG. 7.

[0104] In the second mounting position, the second end portions of the first plate (210) and the second plate (220) can be mounted on the mounting portion (121a) of the second housing (120). The second end portion can be defined as the upper end portion.

[0105] That is, when the first and second plates (210, 220) are turned over at the first mounting position of the first connecting device (200a) and mounted on the mounting portion (121a), the direction in which the first flange (230) protrudes can be varied.

[0106] The configurations of the first connecting device (200a) and the second connecting device (200b) are identical. Therefore, the description regarding the first connecting device (200a) can also be applied to the second connecting device (200b).

[0107] In detail, the second connecting device (200b) may include a first plate (210) having a third flange (240) and a second plate (220) that is bent from the first plate (210).

[0108] As with the description of the mounting position of the first connecting device (200a), the direction in which the third flange (240) protrudes may vary depending on the direction in which the first and second plates (210, 220) are mounted on the mounting portion (121a).

[0118] Referring to FIGS. 7 to 10, a ventilation device (10a) according to an embodiment of the present invention may include a first connection device (200a) mounted at a second mounting position. The configuration of the ventilation device (10a) is different from that of the ventilation device (10) described in FIG. 1 only in the mounting position of the duct connection device (200), and many components constituting the ventilation device are the same.

[0119] In the second mounting position, the first plate (210) of the first connecting device (200a) may constitute at least a portion of a third side portion (113c) among the multiple side portions (113) of the housing (100). In addition, the first flange (230) provided on the first plate (210) may be arranged to protrude in the Y direction from the third side portion (113c).

[0120] That is, when the first connecting device (200a) in FIG. 1 is flipped upside down and mounted on the housing (100), it can have the same appearance as the first connecting device (200b) in FIG. 7.

[0121] Referring to FIGS. 9 and 10, the ventilation device (10) is installed on the ceiling (C) and can be placed between the first wall surface (W1) and the second wall surface (W2).

[0122] A plurality of ducts (D1', D2, D3, D4) may be connected to the housing (100) of the above ventilation device (10). The plurality of ducts may include an internal intake duct (D1'), an exhaust duct (D2), an external air intake duct (D3), and a supply duct (D4).

[0123] The above-mentioned air supply duct (D4) may be connected to a first side portion (113a) among the multiple side portions of the housing (100). The outside air intake duct (D3) and the exhaust duct (D2) may be connected to a second side portion (113b) among the multiple side portions of the housing (100). The first side portion (113a) and the second side portion (113b) may form surfaces facing each other.

[0127] That is, when the first connecting device (200a) is mounted at the second mounting position and the second connecting device (200b) is mounted at the first mounting position as shown in FIG. 9, the first flange (230) can protrude in the Y direction from the third side portion (113c), and the third flange (240) can protrude from the second side portion (113b).

[0128] Let me suggest another example.

[0129] Although not specifically disclosed in the drawing, when the first connecting device (200a) is mounted in the first mounting position as in FIG. 5 and the second connecting device (200b) is mounted in the second mounting position, the first flange (230) may protrude from the first side portion (113a) and the third flange (240) may protrude from the third side portion (113c).

[0130] Let me suggest another example.

[0131] When the first connecting device (200a) is mounted in the second mounting position as shown in FIG. 9 and the second connecting device (200b) is also mounted in the second mounting position, both the first flange (230) and the third flange (240) may protrude in the Y direction from the third side surface (113c).

[0132] Let me suggest another example.

[0133] In the above embodiment, the duct connection device (200a, 200b) is described as being applied to the first flange (230) and the third flange (240), but the duct connection device may also be applied to the second flange (160) or the fourth flange (165). In summary, the degree of freedom in duct connection can be increased by applying the duct connection device to at least one of the first to fourth flanges.

[0134] According to this configuration, the position of connecting the housing of the ventilation device and the duct can be easily changed according to the structure of the indoor space, so there is an advantage in that the installation of the ventilation device is simple and the duct flow path can be secured.

[0135] The present invention relates to a ventilation device, which comprises a duct connection device, allowing the position of the ventilation device's housing and duct to be easily changed according to the structure of the indoor space. Therefore, the invention has significant industrial applicability.
