[0034] For convenience in describing the composite ventilation device (A) according to the present invention, if a non-strict approximate directional reference is specified by referring to the bottom view of FIG. 3 [A] and the inverted front cross-sectional view of [B],

[0035] The cover (20) side is designated as the lower side and the opposite side as the upper side, and the left and right sides are designated in the illustrated state, and the direction is specified and described according to this standard in the detailed description of the invention and claims related to other drawings.

[0036] First, the first ventilation device of FIG. 1 [A-1, A-2, A-3] and FIG. 2 [A, B, C],

[0037] The second ventilation device of FIG. 1 [B-1, B-2, B-3] and FIG. 2 [D], and

[0038] The third ventilation device of FIG. 1 [C-1, C-2], FIG. 2 [E] and FIG. 3

[0039] As shown in the drawings and photographs serving as substitutes for the drawings,

[0040] A composite ventilation device (A) according to the present invention includes a body (10) embedded in the ceiling (see FIG. 2 [B] and FIG. 3) and a cover (20) coupled to the body and equipped with an indoor intake port (s) and an indoor exhaust port (d) exposed to the ceiling.

[0041] In particular, the above cover (20) can be configured to be a bespoke type so that consumers can select various cover designs and easily replace the cover when necessary.

[0042] The above indoor exhaust outlet (d) is positioned off-center on one side (right side in the drawing).

[0043] Next, as can be seen in FIG. 2 [B] and FIG. 3 [A,B], the composite ventilation device (A) according to the present invention,

[0044] It is preferable to further include a ventilation port (v) provided in the body (10) and connected to an air conditioning duct, an intake fan (F) built into the body (10) to provide indoor air intake force from the indoor intake port (s), and a heater (H) provided in the body to generate warm air when the intake fan (F) is exhausted (as shown in FIG. 3 [A], the heater is provided on the indoor exhaust port (d) side).

[0045] In addition, it is preferable that the above ventilation opening (v) be arranged so as to be offset toward the indoor exhaust opening (d).

[0046] In this way, an indoor air intake port (s) is formed overall on two sides of the front and rear, or on three sides of the front, rear, and left side, in a manner that surrounds the cover (20), particularly the shutter (S), from the other side, that is, the left side, to the area extending beyond the center, thereby increasing indoor air intake and exhaust efficiency, and

[0047] The indoor exhaust port (d) located on one side, that is, to the right, and the ventilation port (v) arranged on the outermost side are

[0048] Suitable for the arrangement of intake fans (F) and heaters (H), and for connecting air conditioning ducts (usually connected to ventilation openings (v) via circular corrugated pipes) installed on exposed ceiling materials such as textiles on the ceiling of a building, and for connecting ventilation openings.

[0049] It ensures the operation of the ventilation device's hair or body drying function through a smooth indoor air circulation mode and the ventilation mode that blows indoor air through the vents.

[0050] Next, as can be seen in the drawings related to the first ventilation device and the second ventilation device, the composite ventilation device (A) according to the present invention is,

[0051] The above cover (20) is equipped with a sliding shutter (S) so that the indoor exhaust port (d) or the indoor intake port (s), or both, can be opened according to the operation of a remote controller, and through this, the ventilation device can be covered when not in operation, thereby improving the aesthetics and protecting internal parts.

[0052] The drive of this shutter(S) can be powered by a motor and implemented in various ways, such as using a ball screw, rack gear, chain, or wire.

[0053] Meanwhile, as can be seen in the photograph serving as a drawing in Fig. 2 [E], which is a drawing related to the third ventilation device,

[0054] The above indoor exhaust port (d) is equipped with an exhaust concentrating nozzle (N) or an exhaust dispersing cap (C), so that drying efficiency and comfort can be increased when using the hair or body drying function of the ventilation device through an indoor air circulation mode according to the user's preference and needs, and drying efficiency inside the bathroom can be increased in conjunction with the operation of the heater (H).

[0055] In addition, as can be seen in the drawings related to the first ventilation device, FIG. 1 [A-2] and FIG. 2 [C],

[0056] The indoor exhaust port (d) exposed by the opening of the sliding shutter (S) is equipped with a wind direction control grille (g) so that the direction of airflow can be easily controlled.

[0057] In addition, the indoor intake port(s) or indoor exhaust port(d) is equipped with a sterilization UV lamp (L), so that the user can obtain high satisfaction regarding hygiene.

[0058] As illustrated in the superimposed projection form in the bottom view of FIG. 3 [A], the display (DP) illustrated as the central blue block,

[0059] When in operation, the temperature (°C) and humidity (%) are displayed on the left side, and

[0060] On the right side, a display unit is provided from top to bottom for power ON / OFF, ventilation mode, heater ON / OFF, dehumidification, hair or body drying in ventilation discharge mode, operation of the UV lamp for sterilization (this display unit is indicated as a UV lamp using the drawing symbol 'L' for convenience), shutter OPEN / CLOSE, etc.

[0061] Next, as can be seen in 3 [B], it is preferable to further include a damper (D) composed of a blade (B) that opens an indoor exhaust port (d) or ventilation port (v) according to the operation of a remote controller, and a motor (M) that moves the blade.

[0062] The above motor (M) is connected to the rotation axis (bS) of the blade (B), and the blade (B) lowers during ventilation mode (raises in the state as shown in FIG. 3 [B]) to close the indoor exhaust port (d),

[0063] In the hot and cold air circulation mode for hair or body drying, it rises (or descends as shown in Fig. 3 [B]) to close the ventilation port (v), and the end of the blade is stopped by the sealing jaw (Bt) of the body (10), thereby closing the ventilation port airtightly.

[0064] Alternatively, in order to improve user convenience by enabling a hybrid mode in which the ventilation mode and the circulation mode are performed simultaneously, and which is a partial opening mode of the indoor exhaust and ventilation vents,

[0065] There are two blades, and the motor can move each blade.

[0066] Depending on the need, the motor consists of two units to operate each blade.

[0067] To enable perfect ventilation and circulation modes by having two blades operate simultaneously, or

[0068] A hybrid mode in which ventilation mode and circulation mode are simultaneously achieved can be implemented by closing one half of the indoor exhaust port (d) with the operation of one motor and closing the other half of the ventilation port (v) with the operation of another blade and another motor.

[0069] Ultimately, depending on the operation of the remote controller, a circulation mode or ventilation mode in which the indoor exhaust or ventilation ports are fully opened or closed, or a hybrid mode in which the indoor exhaust and ventilation ports can be partially opened, can be selected.

[0070] Furthermore, in order to enhance price competitiveness and energy efficiency, as illustrated in the modified example of the upper dotted line block of FIG. 3 [B] (the first left block is a schematic front view of the blade, and the right block is a flowchart of the operation),

[0071] The above motor (M) is one, and the rotating shaft (bS) rotated by this motor is also one, and

[0072] The above blade is composed of first and second blades (B1, B2) that are respectively supported by first and second torsion coil springs (bs1, b2) so as to be arranged at different angles to the axis of rotation when no external force is applied (in the state of the second and third blades (B1, B2) within the right block of the upper dotted line block in FIG. 3 [B]),

[0073] The first and second blades (B1, B2) are mounted on a rotation axis (bS) and are coupled in a manner that allows for free rotation due to the tolerance between the outer diameter of the rotation axis and the inner diameter of the mounting portion of each blade.

[0074] The coil portions of the first and second springs (bs1, bs2) of the torsion coil are externally fitted onto the rotation axis, and each of the two ends of the first and second springs (bs1, bs2) is connected to the rotation axis (bS) and the first and second blades (B1, B2).

[0075] According to the rotation of a single rotating shaft by a single motor, the rotational force of the rotating shaft is transmitted to the first and second blades (B1, B2) without delay through the first and second springs (bs1, b2) to move each blade.

[0076] When the motor (M) operates in a circulation mode by the operation of a control unit (e.g., a remote controller), the second blade (B2) first closes the indoor exhaust port (d) (state of the second blade (B1, B2) in the right block).

[0077] As the motor (M) continues to operate (the second blade catches on the flange around the indoor exhaust port (d) and stops moving), the second spring (bs2) deforms (mainly the coil portion of the spring is deformed), thereby counteracting the additional rotation of the rotation shaft (bS), so that the second blade is not damaged even when stopped.

[0078] The first blade (B1) rotates further to close the indoor exhaust port (d) (state of the first blade (B1, B2) in the right block).

[0079] When the above motor (M) operates in ventilation mode, the first blade (B1) first closes the ventilation opening (v) (the state of the third blade (B1, B2) in the right block)

[0080] As the above motor continues to operate (the first blade catches on the flange around the ventilation opening (v), particularly the sealing jaw (Bt), and stops moving), the first spring (bs1) subsequently deforms to counteract additional rotation of the rotation axis (bS), so that the first blade is not damaged even when stopped.

[0081] The second blade (B2) rotates further and closes the ventilation opening (d) (state of the fourth blade (B1, B2) in the right block).

[0082] In order for indoor exhaust and ventilation to occur simultaneously when the above motor (M) operates in a hybrid mode, the second blade (B2) closes the indoor exhaust port (d) and the first blade (B1) is spaced apart from the indoor exhaust port (d) and the ventilation port (v) and is in a neutral position so that the indoor exhaust port (d) is partially closed and the ventilation port (v) is fully open (state of the third blade (B1, B2) in the right block), or the first blade (B1) closes the ventilation port (v) and the second blade (B2) is spaced apart from the indoor exhaust port (d) and the ventilation port (v) and is in a neutral position so that the indoor exhaust port (d) is fully open and the ventilation port (v) is partially closed (state of the fourth blade (B1, B2) in the right block).

[0083] In the above description, commonly known technologies related to the operation of the motor, the sterilization function of the UV lamp, etc., have been omitted, but a person skilled in the art can easily guess, infer, and reproduce them.

[0084] Furthermore, although the present invention has been described above with reference to the attached drawings and primarily focused on a ventilation device having a specific shape and structure, the present invention is capable of various modifications, changes, and substitutions by those skilled in the art, and such modifications, changes, and substitutions should be interpreted as falling within the scope of protection of the present invention.
