Description

Low-temperature heating vaporizing humidifier

[0001] This specification relates to a humidifier, and more specifically, to a low-temperature heating type vaporization humidifier that heats stored humidifying water and discharges the generated water vapor to the outside.

[0002] Unless otherwise indicated herein, the materials described in this section are not prior art to the claims of this application, and their inclusion in this section is not intended to be admitted as prior art.

[0003] In general, humidifiers that artificially generate and spray moisture to increase indoor humidity are classified into heating humidifiers that spray water vapor generated by heating water stored in a tank to a predetermined temperature by a heater into the room, ultrasonic humidifiers that spray fine water particles into the room by vibrating water stored in a tank with ultrasonic waves, or composite humidifiers that combine heating and ultrasonic humidification methods.

[0004] Recently, vaporization type (ventilation type) 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] The aforementioned heated humidifier forms a water tank groove (or humidifying groove) for receiving water on the upper surface of the humidifier body, and a heater is installed in the water tank groove to heat 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] The aforementioned heated humidifier has excellent sterilizing power and is hygienic because it humidifies with the steam generated by heating water inside the humidifier, and the steam spreads well in the indoor space, providing a good humidifying effect.

[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, when the user unconsciously tries to touch the surface of the humidifier, he or she may be burned by the high-temperature steam, so there is a need to improve safety.

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

[0009] An embodiment of the present specification relates to a low-temperature heating type vaporizing humidifier, which allows air sucked in by a blower fan to pass over humidifying water in a heating tank and vaporize the air by heating it by a heater in the heating tank.

[0010] An embodiment of the present specification relates to a low-temperature heating vaporization humidifier capable of sterilizing contaminated air by a UV sterilizing lamp installed at the outlet of a duct that circulates outside air sucked in by a blower fan.

[0011] An embodiment of the present specification relates to a low-temperature heating type vaporization humidifier that moves humidifying water from a reservoir in which humidifying water is stored to a heating tank having a large surface area and then heats the heating tank by a heater, thereby reducing the power consumption of the heater.

[0012] In order to achieve the above and other purposes of this specification, according to one embodiment of this specification,

[0013] Applied to low-temperature heating type vaporization humidifiers,

[0014] A case in which an inlet hole for external air intake is formed through a three-sided surface and an exhaust grill is formed at the top to discharge water vapor to the outside;

[0015] A reservoir formed inside the case and storing humidifying water at a predetermined level;

[0016] An air filter for filtering and purifying foreign substances contained in the external air sucked into the case through the inlet hole when the blower fan installed inside the duct rotates;

[0017] A low-temperature heating type vaporization humidifier is provided, characterized in that it comprises a heating tank in which humidifying water moved from the above-mentioned reservoir through a first pipe connected to a pump is stored at a predetermined water level, and in which the humidifying water inside is heated by a heater mounted on the inner bottom surface to generate steam.

[0018] A low-temperature heating vaporization humidifier according to an embodiment of the present specification having the above-described configuration has the following advantages.

[0019] As the air sucked in by the blower fan passes through the narrowed space, its velocity increases and it comes into contact with the low-temperature heated humidifying water in the heating tank and moves along the upper surface of the water surface. By including the moisture heated to a low temperature by the heater in the heating tank and discharging it to the outside, the efficiency of the humidifier is improved and energy is saved.

[0020] Additionally, contaminated air and bacteria can be sterilized by a UV sterilizing lamp installed at the outlet of the duct that circulates the outside air sucked in by the blower fan.

[0021] In addition, by moving the humidifying water from the storage tank where the humidifying water is stored to a heating tank with a large surface area and heating the heating tank by a heater, the operating time of the heater can be reduced, thereby reducing power consumption.

[0023] Figure 2 is an exploded perspective view of the humidifier shown in Figure 1;

[0027] Fig. 6 is a drawing showing the bottom surface of the case of the humidifier illustrated in Fig. 1.

[0028] Hereinafter, a low-temperature heating type vaporization humidifier according to a preferred embodiment of the present specification will be described in detail with reference to the attached drawings.

[0029] Referring to FIGS. 1 to 6, a low-temperature heating vaporization humidifier according to one embodiment of the present specification

[0030] Applied to low-temperature heating type vaporizing humidifier (A),

[0031] A case (30) (including a lower case (30a) and an upper case (30b)) in which an inlet hole (10) in the shape of a grille through which outside air is introduced is formed penetrating a three-sided surface and an exhaust grille (20) is formed on the upper surface to discharge atomized water vapor to the outside (for example, it may be formed in the shape of a rectangular parallelepiped made of synthetic resin, but it is not meant to be limited thereto);

[0032] A reservoir (40) formed inside the case (30) and storing humidifying water such as tap water at a predetermined water level (for example, it may be formed of stainless steel to prevent corrosion by the stored humidifying water);

[0033] A conventional air filter (70) for filtering and purifying floating substances such as dust contained in the external air sucked into the case (30) through the inlet hole (10) by the suction force generated when a conventional blower fan (60) installed inside a duct (50) rotates (for example, it may be formed in a cylindrical shape, but it is not meant to be limited thereto);

[0034] It is characterized by having a heating tank (100) (for example, it may be formed of stainless steel material with relatively high thermal conductivity so as not to be corroded by the stored humidifying water) which is moved from a reservoir (40) through a first pipe (80) by a pump (p) to store the humidifying water at a predetermined water level, and which heats the humidifying water inside by heating (for example, at a low temperature of 40 to 60°C) by a conventional heater (90) mounted on the inner bottom surface to generate steam.

[0035] As shown in FIGS. 2 and 4, the pump module (210) including the first pipe (80) for moving the humidifying water stored in the aforementioned reservoir (40) to the heating water tank (100) and the pump (p) to which the suction pipe (500) (a tube-shaped hose can be used) for sucking the water in the reservoir (40) into the pump (p) is detachably connected is formed in a replaceable modular form so that the user can directly replace it.

[0036] That is, when the pump (p) is broken or the pump (p) whose service life has expired requires replacement, the pump module cover (700) that is detachably coupled to the opening of the rear cover (600) formed at the rear of the case (30) is separated, and then the first pipe (80) (a tube-shaped hose can be used) and the suction pipe (500) are separated from the pump module (210), so that the broken pump module (210) can be easily replaced with a new pump module by pulling it out through the opening of the rear cover (600) (that is, the process of separating (disassembling) the entire case (30) to replace the pump (p) becomes unnecessary).

[0037] According to a more preferred embodiment, as shown in FIGS. 2 and 3, the aforementioned reservoir (40)

[0038] It is characterized by being able to be withdrawn and stored through an opening formed on the front of the lower case (30a) to allow easy replenishment of humidifying water and cleaning of the interior.

[0039] Due to this, after the aforementioned reservoir (40) is horizontally slidably withdrawn from the lower case (30a), it becomes possible to replenish humidifying water through the through hole (40a) formed on the upper surface of the reservoir (40).

[0040] In addition, the front cover (130) formed to be openable on the front of the case (30) is opened by rotating it around the hinge, and then the water tank (40) is taken out from the case (30) to wash away foreign substances such as water stains formed on the inner surface.

[0041] As shown in FIG. 1, FIG. 2, and FIG. 3, it is characterized by including a conventional LED display unit (110) mounted on the outer surface of the aforementioned reservoir (40) and enabling easy identification of the location of the humidifier (A) at night.

[0042] Accordingly, when going to bed at night with the humidifier (A) running, the LED of the LED display unit (110) mounted on the outer surface of the water tank (40) is turned on by a control signal from the control unit (180) (PCB), so that the location of the humidifier (A) can be easily identified even without separately turning on the indoor lights.

[0043] Accordingly, the user can move along a predetermined path by the LED light of the LED display unit (110), which functions as a normal stand by maintaining the light state while sleeping.

[0044] As shown in Fig. 3, the upper cover (120) having the aforementioned exhaust grill (20) formed on one side is characterized in that it is formed so as to be openable and closable in the upper opening of the upper case (30b).

[0045] Due to this, after opening the upper cover (120) described above to the upper opening of the upper case (30b), it is possible to inspect or replace the heater (90) or air filter (70) installed on the inner bottom surface of the heating tank (100) inside the upper case (30b).

[0046] As shown in FIG. 1 and FIG. 3, the front cover (130) on which the aforementioned LED display unit (110) is mounted is formed to be openable and closable on the case (30).

[0047] Due to this, the front cover (130) described above can be opened with respect to the case (30) by rotating the hinge (not shown) around the central axis, and the LED display (110) fixed to the front cover (130) can be inspected or replaced.

[0048] As shown in Fig. 4, a second pipe (140) for moving humidifying water from the heating water tank (100) to the reservoir (40) so as to maintain the water level of the humidifying water filled in the aforementioned heating water tank (100) at a constant level;

[0049] It is characterized by having a water level control valve (150) that is installed in a manner that can be opened and closed in the second pipe (140) and is switched to an open state when the humidifying water in the heating water tank (100) exceeds the set water level to drain the humidifying water in the heating water tank (100) into the water storage tank (40).

[0050] Although not shown in the drawing, the water level control valve (150) mentioned above

[0051] It is characterized in that a conventional solenoid valve (not shown) is used to open the second pipe (140) by switching to an open state when an electric signal is applied from the control unit (180).

[0052] Due to this, it is possible to control the level of humidifying water filled in the heating tank (100) depending on the environment in which the aforementioned humidifier (A) is used.

[0053] As described above, the water level of the humidifying water filled in the heating tank (100) is maintained at a constant level. When the water level sensor (not shown) installed in the heating tank (100) detects that the set water level has been exceeded, the water level control valve (150) installed in a closable manner in the second pipe (140) is opened so that the excess humidifying water in the heating tank (100) can be drained to the reservoir (40) through the second pipe (140).

[0054] At this time, the technical content of opening the second pipe (140) by the water level control valve (150) (as an example, a solenoid valve may be used) that is switched to an open state in response to an electric signal applied from the control unit (180) is substantially the same as that commonly used in the technical field to which this specification pertains, so a detailed description thereof is omitted.

[0055] As shown in FIG. 2 and FIG. 4, the capacity of the aforementioned reservoir (40) is characterized by being formed to be larger than the capacity of the heating tank (100).

[0056] That is, the capacity of the aforementioned water reservoir (40) is formed to be larger than that of the heating water tank (100), and the heating water tank (100) with a small capacity but a large surface area is heated at a low temperature by the heater (90) to generate water vapor and increase the amount of moisture evaporated by the wind, thereby reducing the amount of power consumed to use the humidifier (A).

[0057] That is, by heating a small amount of humidifying water filled in a heating tank (100) to a low temperature by a heater (90) and operating the humidifier (A) with wind using a blower fan (60), water vapor can be generated and discharged with a small amount of electricity.

[0058] On the other hand, conventional heating humidifiers have a single reservoir for storing humidifying water and are formed with a large capacity, so they use a large-capacity heater to heat a large amount of humidifying water filled in the reservoir, and by humidifying using the rising air pressure when the water boils, the time for the heater to operate becomes longer, which increases the power consumption.

[0059] As shown in FIGS. 2 and 4, it is characterized by having an ultraviolet sterilizing lamp (160) (as an example, a conventional UV sterilizing lamp may be used) installed at the outlet (50a) of the aforementioned duct (50) and irradiating ultraviolet rays to the air passing through the duct (50) to sterilize polluted air and bacteria in the air.

[0060] Due to this, the external air is sucked into the case (30) by passing through the inlet hole (10) formed in the case (30) by the suction force generated when the aforementioned blower fan (60) rotates, so that floating substances such as dust contained in the external air are filtered by the air filter (70) and then introduced into the duct (50).

[0061] At this time, bacteria or contaminated air contained in the air passing through the outlet (50a) of the duct (50) are sterilized by ultraviolet rays from an ultraviolet sterilizing lamp (160) installed at the outlet (50a) of the aforementioned duct (50) and irradiating the air passing through.

[0062] Therefore, when the blower fan (60) rotates, the outside air passes through the inlet hole (10) and is sucked into the case (30), so that floating substances in the air can be filtered and purified by the air filter (70).

[0063] In addition, after being purified by the air filter (70), the air passing through the outlet (50a) of the duct (50) is sterilized by irradiation with an ultraviolet sterilizing lamp (160) and then discharged through the exhaust grill (20) to the outside of the humidifier (A), thereby enabling the discharge of clean air indoors.

[0064] At this time, if the ultraviolet sterilizing lamp (160) installed at the outlet (50a) of the duct (50) is installed in the width direction at the long-hole outlet (50a) to increase the irradiation area of ​​the air, the efficiency of sterilizing polluted air and bacteria in the air can be increased (see Fig. 2).

[0065] As shown in Fig. 2, an ultraviolet sterilizing lamp (220) may be installed to sterilize humidifying water stored at an arbitrary water level in the aforementioned reservoir (40). The ultraviolet sterilizing lamp (220) is positioned above an opening formed with a predetermined area in a lid (40b) that is formed to be openable and closable in the opening of the reservoir (40), and is formed to be able to irradiate ultraviolet rays into the interior of the reservoir (40) by penetrating the opening, thereby enabling constant sterilization of humidifying water stored in the reservoir (40).

[0066] As shown in Fig. 4, the outlet cross-section of the aforementioned duct (50) is reduced compared to the inlet cross-section, and a groove (170) is 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). When the blower fan (60) rotates, the external air sucked into the case (30) through the inlet hole (10) passes through the outlet (50a) of the duct (50), and after the direction of movement is changed by the groove (170), it moves toward the discharge grill (20) while contacting (or colliding with) the surface of the humidifying water of the heating water tank (100).

[0067] Due to this, the external air sucked in through the inlet hole (10) of the case (30) due to the rotation of the aforementioned blower fan (60) passes through the air filter (70) and then the duct (50).

[0068] At this time, the air pressure flow rate passing through the narrowed outlet (50a) of the duct (50), which is formed to be smaller than the cross-section of the duct (50) inlet, becomes faster. The air pressure flow rate that has become faster as it passes through the outlet (50a) of the duct (50), changes its direction of movement toward the humidifying water surface of the heating water tank (100) by the groove (170) formed on the inner surface of the upper cover (120).

[0069] The air, whose direction of movement has been changed by the groove (170), comes into contact with the surface of the humidifying water in the heating tank (100) and moves toward the discharge grill (20). At this time, the humidifying water is heated by the heater (90) installed on the inner bottom surface of the heating tank (100) (for example, a low temperature of 40 to 60°C) to generate steam.

[0070] As described above, when the air passing through the duct outlet (50a) moves toward the discharge grill (20) while coming into contact with (or colliding with) the humidifying water surface of the heating tank (100), 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.

[0071] As shown in Fig. 6, the bottom surface of the case (30) described above, more specifically, the bottom surface of the reservoir (40), may be provided with rollers (190) that are rotatably formed at the four corners and enable the vaporizing humidifier (A) to be easily moved.

[0072] At this time, a bolt-shaped flow prevention device (200) that is screw-connected to the bottom surface of the reservoir (40) at a position close to the roller (190) can be provided so as to restrict the free movement of the vaporizing humidifier (A) by the roller (190).

[0073] Due to this, the bottom surface of the flow prevention device (200) is maintained at a position lower than the bottom surface of the roller (190) by rotating the flow prevention device (200) in the reverse direction (counterclockwise) to partially relax it (at this time, the roller (190) is spaced from the bottom surface).

[0074] Therefore, it is possible to prevent the vaporizing humidifier (A) from freely moving along the floor surface.

[0075] In the drawing, the unexplained symbol 400 is a third pipe for directly draining the washing water generated when washing the inside of the heating water tank (100) into the storage tank (40).

[0076] Hereinafter, a low-temperature heating type vaporizing humidifier (A) according to one embodiment of the present specification is described in detail with reference to the attached drawings.

[0077] As shown in FIGS. 1 to 6, 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 withdrawable on the front surface of the aforementioned lower case (30a), and then moved into the lower case (30a). At this time, the humidifying water filled in the reservoir (40) is moved to the heating water tank (100) through the first pipe (80) by the operation of the pump (p).

[0078] By operating the corresponding button of the control unit (180) formed on one side of the upper surface of the upper cover (120) described above to rotate the blower fan (60) installed at the entrance of the duct (50) inside the case (30), indoor air is sucked into the interior through the inlet hole (10) formed through the three-sided case (30).

[0079] Floating substances such as dust contained in the indoor air passing through the inlet (10) are filtered by a conventional air filter (70) installed inside the case (30), so that the indoor air can be purified.

[0080] At this time, the technical content of filtering and purifying floating substances, etc. contained in the indoor air sucked into the case (30) when the aforementioned blower fan (60) rotates by the air filter (70) is substantially the same as the filtration filter commonly used in the technical field to which this specification pertains, so a detailed description of their configuration and function is omitted.

[0081] The air passing through the air filter (70) by the suction force of the aforementioned blower fan (60) passes through the inlet of the duct (50) and moves along the internal air movement passage and is discharged through the duct outlet (50a).

[0082] At this time, as the cross-section of the outlet (50a) of the duct (50) is formed relatively smaller than the cross-section of the inlet, the discharge speed of the air pressure passing through the narrowed outlet (50a) of the duct (50) becomes faster.

[0083] Accordingly, the air pressure passing through the outlet (50a) of the duct (50) collides with the groove (170) formed curvedly on the inner surface of the upper cover (120) so as to face the bottom surface of the heating tank (100).

[0084] The direction of movement of the air pressure colliding with the home (170) changes to the upper part of the humidifying water in the heating tank (100), contacts (or collides) with the surface of the humidifying water, and moves along the surface of the humidifying water toward the discharge grill (20).

[0085] As described above, when the air pressure passing through the duct outlet (50a) 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 lowering the heating temperature of the heater (90) that heats the humidifying water and reducing the heating time.

[0086] Accordingly, the water vapor generated by the humidifying water in the heating tank (100) being heated by the heater (90) passes through the exhaust grill (20) formed on one side of the upper cover (120) and is discharged to the outside of the humidifier (A).

[0087] By forming the upper part of the aforementioned heating tank (100) to be open and having a flat and wide surface area to increase the amount of humidifying water received, the air passing through the duct outlet (50a) passes over the surface of the humidifying water forming the large surface area of ​​the heating tank (100), thereby absorbing a lot of moisture and discharging it to the outside through the discharge grill (20), thereby increasing the humidifying efficiency.

[0088] Meanwhile, the water level of the humidifying water filled in the heating tank (100) can be adjusted depending on the environment in which the aforementioned humidifier (A) is used.

[0089] As described above, 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) installed in the second pipe (140) to be openable is opened by an electric signal applied from the control unit (180), thereby allowing the excess humidifying water in the heating tank (100) to be drained to the reservoir (40) through the second pipe (140).

[0090] Although not shown in the drawing, the low-temperature heating type vaporizing humidifier according to the embodiment of the present specification is formed with a circulation structure that moves humidifying water in a reservoir (40) to a heating tank (100) through a pump (p) and a first pipe (80), and when the water level of the heating tank (100) exceeds a set value or when the heating tank (100) is cleaned, drains the water to the reservoir (40) through a water level control valve (150) and a second pipe (140). Therefore, when the humidifier needs to be cleaned, scale (referring to an alkaline mineral component) stuck to the reservoir (40) and the heating tank (100), or the inside of the first pipe (80) and the second pipe (140) through which the humidifying water passes, can be easily removed using citric acid.

[0091] Although the above-described specification has been described with reference to exemplary preferred technical ideas, those skilled in the art to which the specification pertains will be able to make various modifications and equivalent other embodiments without departing from the essential characteristics of the specification.

[0092] In other words, the disclosed content is merely an example, and can be modified and implemented in various ways by a person having ordinary knowledge in the relevant technical field without departing from the gist of the claims claimed in the claims, so the scope of protection of the disclosed content is not limited to the specific embodiments described above.

[0093] Therefore, the embodiments disclosed in this specification are not intended to limit the technical idea but to explain it, and the protection scope of the specification should be interpreted by the technical idea of ​​the claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of rights of this specification.

[0094] The present invention relates to a low-temperature heating vaporization humidifier for humidifying an indoor space by heating humidifying water stored in a tank by a heater, generating vapor and discharging it to the outside in an atomized state.
