Description

Heated evaporative humidifier

[0001] The present disclosure relates to a humidifier, and more specifically, to a heated vaporizing humidifier that heats stored humidifying water to generate water vapor and discharges it to the outside.

[0002]

[0003] Humidifiers that artificially generate and spray moisture to increase indoor humidity can be classified according to the method of moisture generation into a heated humidifier, which sprays water vapor into the room generated by heating water stored in a water tank to a predetermined temperature using a heater; an ultrasonic humidifier, which sprays finely atomized water particles into the room by vibrating water stored in a water tank using ultrasound; or a hybrid humidifier that combines the heated humidification method and the ultrasonic humidification method.

[0004] Recently, evaporative (air-blowing) humidifiers are also used, which perform humidification by immersing a humidifying element (humidifying filter) in a water tank and then vaporizing the water absorbed by the humidifying element using a blower fan.

[0005] A heated humidifier forms a water tank groove (or humidification groove) for water collection on the upper surface of the humidifier body, and installs a heater in the water tank groove to heat the water supplied to the water tank groove by a water tank to generate steam. The steam generated in the water tank groove is atomized through an atomizing tube and discharged to the outside through the upper nozzle of the atomizing tube to humidify the room.

[0006] Heated humidifiers humidify using steam generated by heating water inside the unit, so they have excellent sterilization capabilities, making them hygienic, and the steam spreads well throughout the indoor space, allowing for good humidification effects.

[0007] However, since heated humidifiers heat the water inside to generate steam and discharge it to the outside, the steam temperature on the surface of the humidifier becomes high, and as a result, if a user unconsciously tries to touch the surface of the humidifier, they may suffer burns from the high-temperature steam, so safety improvements may be required.

[0008] A heated humidifier is disclosed in Korean Patent Publication No. 10-2024-0007983 (published on January 18, 2024).

[0009]

[0010] One embodiment of the present disclosure can provide a heated vaporizing humidifier that allows air sucked in by a blower fan to be vaporized by heating by a heater in the heating tank when the air passes over the humidifying water in the heating tank.

[0011] One embodiment of the present disclosure may provide a heated evaporative humidifier capable of sterilizing contaminated air by means of a UV sterilization lamp installed at the outlet of a duct that circulates external air sucked in by a blower fan.

[0012] One embodiment of the present disclosure can provide a heated evaporative humidifier that reduces the power consumption of a heater by moving water for humidification from a reservoir in which water for humidification is stored to a heating tank with a large surface area and then heating the heating tank by a heater.

[0013] One embodiment of the present disclosure can provide a heated vaporizing humidifier that can efficiently save energy by means of a duct that accelerates air and a groove that redirects the accelerated air toward a heated water bath.

[0014]

[0015] To achieve the purpose of the present disclosure, a humidifier according to one embodiment of the present disclosure comprises: a main body housing including a plurality of inlet holes; a water tank disposed at the bottom of the main body housing; an air filter disposed on the water tank, wherein the air filter includes a blower fan and a duct spatially connected to the blower fan, wherein the duct includes an inlet and an outlet, wherein the outlet cross-sectional area is formed smaller than the inlet cross-sectional area, so that air passing through the duct is accelerated; and a heating water tank disposed on the air filter, wherein the heating water tank includes a heater disposed at the bottom and connected to the water tank by at least one pipe, and heats the stored water by heating the heater, wherein air introduced into the main body housing through the inlet holes is directed to the duct via the air filter by the blower fan, and the accelerated air can be discharged to the outside of the main body housing in a humidified state by mixing with water vapor by the blower fan in the heating water tank.

[0016]

[0017] A heated vaporizing humidifier according to one embodiment of the present disclosure has the following advantages.

[0018] According to one embodiment, air sucked in by a blower fan passes through a narrowing space and, while the flow velocity increases, comes into contact with the heated water for humidification in a heating tank and moves along the surface of the water, and by discharging to the outside the water that includes moisture heated to a low temperature by a heater in the heating tank, the efficiency of the humidifier can be improved and energy can be saved.

[0019] In addition, according to one embodiment, contaminated air and bacteria can be sterilized by a UV sterilization lamp installed at the outlet of a duct that circulates external air sucked in by a blower fan.

[0020] In addition, according to one embodiment, humidifying water is transferred from a water reservoir in which humidifying water is stored to a heating tank with a large surface area, and the heating tank is heated by a heater, thereby reducing the operating time of the heater and reducing power consumption.

[0021] In addition, according to one embodiment, air is accelerated by the duct structure of the air filter, so that energy can be saved efficiently.

[0022] In addition, according to one embodiment, the air accelerated by the groove structure formed in front of the outlet can be diverted toward the heating tank, thereby allowing for efficient energy saving.

[0034]

[0035] Hereinafter, a heated vaporizing humidifier according to a preferred embodiment of the present disclosure will be described in detail with reference to the attached drawings.

[0036] Referring to FIGS. 1 to 6, a heated vaporizing humidifier according to one embodiment of the present disclosure is applied to a heated vaporizing humidifier (A), and a main body housing (30) (which may include a lower housing (30a) and an upper housing (30b)) in which an inlet hole (10) in the form of a grille for external air to be introduced is formed through a trihedron, and an exhaust grille (20) for discharging water vapor in an atomized state to the outside is formed on the upper part (as an example, it may be formed in the shape of a rectangular parallelepiped made of synthetic resin material, but is not limited thereto);

[0037] According to one embodiment, the humidifier (A) may include a water tank (40) formed inside the main body housing (30) and in which humidifying water, such as tap water, is stored at a predetermined water level (for example, it may be formed of stainless steel so as not to be corroded by the stored humidifying water).

[0038] According to one embodiment, the humidifier (A) may include a conventional air filter (70) for filtering and purifying airborne substances, such as dust, contained in the external air sucked into the main body housing (30) through the inlet port (10) by the suction force generated when a conventional blower fan (60) installed inside a duct (50) rotates (as an example, it may be formed in a cylindrical shape, but is not limited thereto);

[0039] According to one embodiment, the humidifier (A) may include a heating water tank (100) in which humidifying water, which is moved from a water tank (40) through a first pipe (80) by a pump (p), is stored at a predetermined water level, and which heats the humidifying water inside to generate steam by heating a conventional heater (90) mounted on the inner bottom surface (for example, a low temperature of 40 to 60°C); the heating water tank (100) may be formed of stainless steel so as not to be corroded by the stored humidifying water, and has relatively high thermal conductivity.

[0040] According to one embodiment, the humidifier (A) is formed as a replaceable modular type, wherein the pump module (210) includes a first pipe (80) for moving humidifying water stored in a reservoir (40) to a heating tank (100), and a pump (p) to which a suction pipe (500) (a tube-shaped hose may be used) for sucking water from the reservoir (40) into the pump (p) is detachably connected. This allows the user to replace the pump module directly. That is, when the pump (p) is broken or requires replacement due to the end of its service life, the pump module cover (700), which is detachably coupled to the opening of the rear cover (600) formed at the rear of the main body housing (30), is separated, and the first pipe (80) (a tube-shaped hose may be used) and the suction pipe (500) are separated from the pump module (210), thereby allowing the broken pump module (210) to be pulled out through the opening of the rear cover (600) and simply replaced with a new pump module (i.e., the process of separating (disassembling) the entire main body housing (30) to replace the pump (p) may become unnecessary).

[0041] According to one embodiment, the water tank (40) is characterized by being housed in a manner that allows for easy replenishment of humidifying water and cleaning of the interior through an opening formed on the front of the lower housing (30a). As a result, after withdrawing the water tank (40) from the lower housing (30a) by sliding it horizontally, humidifying water can be replenished through a through hole (40a) formed on the upper surface of the water tank (40).

[0042] In addition, according to one embodiment, the humidifier (A) can open a front cover (130) formed to be openable on the front of the main body housing (30) by rotating it around a hinge part, and then pull out a water tank (40) from the main body housing (30) to wash foreign substances such as water stains formed on the inner surface.

[0043] According to one embodiment, the humidifier (A) is mounted on the outer surface of the water tank (40) and is characterized by including a conventional LED display (110) that allows the location of the humidifier (A) to be easily identified at night. As a result, when sleeping with the humidifier (A) in operation at night, the LED of the LED display (110) mounted on the outer surface of the water tank (40) is turned on by a control signal from the control unit (180) (PCB), thereby allowing the location of the humidifier (A) to be easily identified even without turning on the indoor light separately. Accordingly, the user can move along a predetermined path by the LED light of the LED display (110), which maintains the illuminated state while sleeping and functions as a conventional stand.

[0044] According to one embodiment, the humidifier (A) is characterized by having an upper cover (120) formed on one side with an exhaust grille (20) formed thereon, which is formed to be openable and closable at the upper opening of the upper housing (30b). As a result, after opening the upper cover (120) at the upper opening of the upper housing (30b), it is possible to inspect or replace a heater (90) or an air filter (70) installed on the inner bottom surface of a heating tank (100) inside the upper housing (30b).

[0045] According to one embodiment, the humidifier (A) is characterized by having a front cover (130) on which an LED display (110) is mounted, which is formed to be openable and closable on the main body housing (30). As a result, the aforementioned front cover (130) can be rotated around a hinge part (not shown) as a central axis to open it against the main body housing (30), and then the LED display (110) fixed to the front cover (130) can be inspected or replaced.

[0046] According to one embodiment, the humidifier (A) may include a second pipe (140) for moving the humidifying water of the heating tank (100) to a reservoir (40) so as to maintain a constant level of the humidifying water filled in the heating tank (100); and a water level control valve (150) installed to be openable and closable in the second pipe (140), which switches to an open state when the humidifying water of the heating tank (100) exceeds a set level to drain the humidifying water of the heating tank (100) into the reservoir (40).

[0047] Although not shown in the drawing, the water level control valve (150) is characterized by the use of a conventional solenoid valve (not shown) to open the second pipe (140) when an electrical signal is applied from the control unit (180). As a result, the water level of the humidifying water filled in the heating tank (100) can be controlled according to the environment in which the aforementioned humidifier (A) is used.

[0048] According to one embodiment, the water level of the humidifying water filled in the heating tank (100) is maintained at a constant level. When a water level sensor (not shown) installed in the heating tank (100) detects that the water level exceeds the set level, a water level control valve (150) installed to be openable and closable in the second pipe (140) can be opened to drain the excess humidifying water from the heating tank (100) into the reservoir (40) through the second pipe (140). At this time, the technical content of opening the second pipe (140) by the water level control valve (150) (for example, a solenoid valve may be used) which is switched to an open state by an electrical signal applied from the control unit (180) is substantially the same as that commonly used in the technical field to which this disclosure belongs, so a detailed description thereof is omitted.

[0049] According to one embodiment, the capacity of the water tank (40) is formed to be larger than the capacity of the heating tank (100). That is, the capacity of the aforementioned water tank (40) is formed to be larger than that of the heating tank (100), but the heating tank (100), which has a smaller capacity but a larger surface area, is heated to a low temperature by the heater (90) to generate steam, and the amount of water evaporation is increased by the wind, thereby reducing the amount of power consumed to use the humidifier (A). That is, by heating a small amount of humidifying water filled in the heating tank (100) to a low temperature by the heater (90) and operating the humidifier (A) by the wind using the blower fan (60), steam can be generated and discharged with less power.

[0050] On the other hand, conventional heated humidifiers have a single large-capacity water tank for storing water for humidification, and thus a large-capacity heater is used to heat the large amount of water filled in the tank. Since humidification is achieved by utilizing the rising air pressure when the water boils, the time the heater is operated is prolonged, which can lead to an increase in power consumption.

[0051] According to one embodiment, the humidifier (A) is installed at the outlet (50a) of the duct (50) and is characterized by having an ultraviolet sterilization lamp (160) (as an example, a conventional UV sterilization lamp may be used) for sterilizing contaminated air and bacteria in the air by irradiating ultraviolet rays onto the air passing through the duct (50). As a result, external air is sucked into the main body housing (30) by passing through the inlet hole (10) formed through the main body housing (30) by the suction force generated when the aforementioned blower fan (60) rotates, and thus suspended substances such as dust contained in the external air can be filtered by the air filter (70) and then introduced into the duct (50). At this time, bacteria or contaminated air contained in the air passing through the outlet (50a) of the duct (50) can be sterilized by ultraviolet rays from an ultraviolet sterilization lamp (160) that is installed at the outlet (50a) of the aforementioned duct (50) and irradiates the air passing through.

[0052] Therefore, when the blower fan (60) rotates, external air passes through the inlet port (10) and is sucked into the main body housing (30), so that airborne particles can be filtered and purified by the air filter (70).

[0053] Additionally, after being purified by the air filter (70), the air passing through the outlet (50a) of the duct (50) is sterilized by irradiation of the ultraviolet sterilization lamp (160) and passed through the discharge grille (20) to be discharged outside the humidifier (A), thereby allowing clean air to be discharged into the room. At this time, if the ultraviolet sterilization lamp (160) installed at the outlet (50a) of the duct (50) is installed in the width direction of the elongated outlet (50a) to increase the irradiation area of ​​the air, the efficiency of sterilizing contaminated air and bacteria in the air can be increased (see FIG. 2).

[0054] As shown in FIG. 2, an ultraviolet sterilization lamp (220) may be installed to sterilize the humidifying water stored in the reservoir (40) at an arbitrary level. The ultraviolet sterilization lamp (220) is positioned above an opening formed with a predetermined area in a lid (40b) that is formed to be openable and closable at the opening of the reservoir (40), and is formed to irradiate ultraviolet rays into the interior of the reservoir (40) through the opening, thereby allowing the humidifying water stored in the reservoir (40) to be sterilized at all times.

[0055] As illustrated in FIG. 4, according to one embodiment, the humidifier (A) is provided with a groove (170) formed curvedly on the inner surface of the upper cover (120) so as to face the outlet of the duct (50) and a part of the bottom surface of the heating water tank (100), and is characterized in that when the blower fan (60) rotates, external air sucked into the main body housing (30) through the inlet hole (10) passes through the outlet (50b) of the duct (50), and after the direction of movement is changed by the groove (170), it moves toward the discharge grill (20) while coming into contact (or colliding) with the surface of the humidifying water of the heating water tank (100).

[0056] As a result, external air sucked in through the inlet port (10) of the main body housing (30) due to the rotation of the blower fan (60) may pass through the air filter (70) and then through the duct (50). At this time, the air pressure flow velocity may increase as it passes through the narrowed outlet (50a) of the duct (50), which is formed to be smaller than the cross-section of the duct (50) inlet. The air pressure, whose flow velocity has increased after passing through the outlet (50a) of the duct (50), may have its direction of movement changed toward the water surface for humidification of the heating tank (100) by the groove (170) formed on the inner surface of the upper cover (120). The air, whose direction of movement has been changed by the groove (170), comes into contact with the water surface for humidification of the heating tank (100) and may move toward the discharge grill (20). At this time, the water for humidification may be heated to generate steam by heating the heater (90) installed on the inner bottom surface of the heating tank (100) (for example, a low temperature of 40 to 60°C).

[0057] As described above, when air passing through the duct outlet (50b) comes into contact (or collides) with the surface of the humidifying water in the heating tank (100) and moves toward the discharge grill (20), the heater (90) that heats the humidifying water can be operated at a low temperature, and the operating time can be reduced to reduce power consumption.

[0058] As shown in FIG. 6, according to one embodiment, the humidifier (A) may be provided with a roller (190) that is rotatably formed at the four corners of the bottom surface of the main body housing (30), more specifically, the bottom surface of the water tank (40), and allows the vaporizing humidifier (A) to be easily moved. At this time, a bolt-shaped anti-movement member (200) may be provided that is screw-coupled to the bottom surface of the water tank (40) at a position close to the roller (190) so as to restrict the vaporizing humidifier (A) from moving freely by the roller (190). As a result, by rotating the anti-movement member (200) in the reverse direction (counterclockwise) to partially loosen it, the bottom surface of the anti-movement member (200) may be maintained at a lower position than the bottom surface of the roller (190) (at this time, the roller (190) is spaced apart from the bottom surface). Therefore, it is possible to prevent the vaporizing humidifier (A) from moving freely along the bottom surface. In the drawing, the unexplained reference numeral 400 is a third pipe for directly draining the washing water generated when washing the inside of the heating tank (100) into the reservoir (40).

[0059]

[0060] Hereinafter, a heated vaporizing humidifier (A) according to one embodiment of the present disclosure will be described in detail with reference to the attached drawings.

[0061] As shown in FIGS. 1 to 6, according to one embodiment, humidifying water is filled to maintain a predetermined water level through a through hole (40a) formed on the upper surface of a reservoir (40) that is formed to be removable on the front of a lower housing (30a), and then moved into the lower housing (30a). At this time, the humidifying water filled in the reservoir (40) can be moved to a heating water tank (100) through a first pipe (80) by driving a pump (p).

[0062] According to one embodiment, the humidifier (A) can be sucked into the interior through an inlet hole (10) formed through the main body housing (30) in a three-sided shape by operating a corresponding button of a control unit (180) formed on one side of the upper surface of the upper cover (120) to rotate a blower fan (60) installed at the inlet of a duct (50) inside the main body housing (30).

[0063] According to one embodiment, airborne substances such as dust contained in the indoor air passing through the inlet port (10) are filtered by a conventional air filter (70) installed inside the main body housing (30), thereby purifying the indoor air. At this time, since the technical content of purifying the airborne substances contained in the indoor air sucked into the main body housing (30) when the blower fan (60) rotates by filtering them by the air filter (70) is applied substantially identically to the filtration filters commonly used in the technical field to which this disclosure belongs, a detailed description of their configuration and function is omitted.

[0064] According to one embodiment, in a humidifier (A), air passing through an air filter (70) by the suction force of a blower fan (60) passes through the inlet of a duct (50), moves along an internal air passage, and can be discharged through a duct outlet (50b). At this time, as the cross-section of the outlet (50b) of the duct (50) is formed to be relatively smaller than the cross-section of the inlet, the discharge speed of the air pressure passing through the outlet (50b), where the width of the duct (50) is narrowed, can be increased.

[0065] Accordingly, the air pressure passing through the outlet (50b) of the duct (50) may collide with the groove (170) formed curvedly on the inner surface of the upper cover (120) so as to be opposite the bottom surface of the heating tank (100). The direction of movement of the air pressure colliding with the groove (170) may be changed to the upper side of the humidifying water of the heating tank (100) to come into contact (or collide) with the surface of the humidifying water, and may move along the surface of the humidifying water toward the discharge grill (20).

[0066] When the air pressure passing through the duct outlet (50b) comes into contact with the surface of the humidifying water in the heating tank (100) and moves toward the discharge grill (20), the humidifying water is heated and vaporized by the heating of the heater (90) installed on the inner bottom surface of the heating tank (100), thereby allowing the heating temperature of the heater (90) that heats the humidifying water to be lowered and the heating time to be reduced.

[0067] Accordingly, the water vapor generated by heating the humidifying water of the heating tank (100) by the heater (90) can be discharged to the outside of the humidifier (A) by passing through the discharge grille (20) formed on one side of the upper cover (120).

[0068] By forming the upper part of the heating tank (100) open and having a flat and wide surface area to increase the amount of humidifying water contained therein, the air passing through the duct outlet (50a) passes over the surface of the humidifying water that forms a large surface area of ​​the heating tank (100), thereby retaining a large amount of moisture and discharging it to the outside through the discharge grill (20), so that the humidification efficiency can be increased.

[0069] Meanwhile, the water level of the humidifying water filled in the heating tank (100) can be adjusted according to the environment in which the aforementioned humidifier (A) is used.

[0070] The water level of the humidifying water filled in the heating tank (100) is controlled to be maintained at a constant level. When the water level of the heating tank (100) exceeds a set value, the water level control valve (150), which is installed to be openable and closable in the second pipe (140) by an electrical signal applied from the control unit (180), is opened so that the excess humidifying water of the heating tank (100) can be drained into the reservoir (40) through the second pipe (140).

[0071] Although not shown in the drawings, the low-temperature heating type vaporizing humidifier according to the embodiment of the present disclosure is formed with a circulation structure that moves humidifying water from a water tank (40) to a heating tank (100) through a pump (p) and a first pipe (80), and allows drainage to the water tank (40) through a water level control valve (150) and a second pipe (140) when the water level of the heating tank (100) exceeds a set value or when the heating tank (100) is to be cleaned. Therefore, when cleaning of the humidifier is required, scale (referring to alkaline mineral components) adhering to the inside of the water tank (40), the heating tank (100), or the first pipe (80) and the second pipe (140) through which humidifying water passes can be easily removed using citric acid.

[0072]

[0073] Hereinafter, with reference to FIGS. 4 and 5, a duct structure and an air path according to one embodiment, through which blown air is accelerated, will be described. For reference, each dotted arrow (①-④) may be an arrow indicating an air path through which air moves.

[0074] Referring to FIGS. 4 and 5, according to one embodiment, the vaporizing humidifier may include a main body housing (30), a water reservoir (40) disposed at the bottom of the main body housing (30), an air filter (70), and a heating water tank (100). According to one embodiment, the water reservoir (40) may be disposed at the bottom of the main body housing (30), and the air filter (70) may be disposed between the water reservoir (40) and the heating water tank (100).

[0075] According to one embodiment, the air filter (70) may include a blower fan (60) and a duct (50). According to one embodiment, the blower fan (60) may be a device that blows air drawn in through a plurality of inlet holes (10) toward the duct (50) and the heating tank (100) and filters the air. According to one embodiment, the air filter (70) may include a duct (50) spatially connected to the blower fan (60).

[0076] According to one embodiment, the duct (50) may be an air path for sending air introduced into the main body housing (30) through a plurality of inlet holes (10) to a heating water tank (100) by a blower fan (60). According to one embodiment, the duct (50) may be a part of an air filter (70) and may include an inlet (50a) and an outlet (50b). According to one embodiment, the inlet (50a) of the duct (50) may be perpendicular to the direction in which the outlet (50b) faces.

[0077] According to one embodiment, the duct (50) may be formed such that the cross-sectional area of ​​the outlet (50b) is smaller than that of the inlet (50a). For example, the cross-sectional area of ​​the inlet (50a) and / or the outlet (50b) is substantially rectangular, but it is not limited to being rectangular and various shapes may be possible.

[0078] According to one embodiment, the cross-sectional area of ​​the duct (50) may be shaped to gradually decrease from the inlet (50a) toward the outlet (50b). For example, the rectangular cross-sectional area of ​​the inlet (50a) may be shaped to gradually decrease toward the outlet (50b). According to one embodiment, the duct (50) is formed such that the cross-sectional area of ​​the outlet (50b) is smaller than the cross-sectional area of ​​the inlet (50a), so that the air passing through the outlet (50b) can be accelerated.

[0079] According to one embodiment, the first width (w1) (e.g., vertical width) at the inlet (50a) is larger than the first width (w2) at the outlet (50b), and the first width (w1) at the inlet (50a) may have a shape in which the first width gradually decreases as it approaches the outlet (50b) compared to the first width (w) at the outlet (50b). According to one embodiment, the second width (w3) (e.g., horizontal width) of the duct (50) may have a shape that is approximately constant from the inlet (50a) to the outlet (50b) or may vary.

[0080] According to one embodiment, the duct (50) can have air introduced through an inlet (50a) in a first direction (①) by the operation of a blower fan (60), and can discharge air through an outlet (50b) in a second direction (②) perpendicular to the first direction (①). According to one embodiment, the air accelerated after passing through the outlet (50b) can move toward a third direction (③) perpendicular to the second direction (②) and pass over the heating water tank (100).
