20240200803
This application claims priority under 35 U.S.C. § 119 to Korean Application No. 10-2022-0177793, filed in Korea on Dec. 19, 2022, whose entire disclosure(s) is/are hereby incorporated by reference.
This disclosure relates to a humidifier, and more particularly, to a humidifier that generates humidified air through heating or ultrasonic vibration.
A humidifier is an apparatus that evaporates water and discharges humidified air having high moisture content. A humidifier can generate humidified air by vaporizing water through natural evaporation, heat evaporation, or ultrasonic vibration.
Each evaporation method has advantages and disadvantages. In the case of natural evaporation, there is a problem in that a user must frequently manage the humidifying medium used.
In the case of evaporation by ultrasonic vibration, there is a problem that the humidified air may not flow actively into the indoor space as the supplied water is atomized by ultrasonic vibration, a problem that when unsterilized water is humidified, unpleasant humidified air flows into the indoor space, and a problem that ultrasonic vibrator is vulnerable to high temperature heat.
In the case of heat evaporation, safety accidents may occur if hot humidified air is discharged directly.
Korean registered patent KR 10-0158806 discloses a humidifier that humidifies water supplied from a water tank by heating and ultrasonic vibration.
However, the prior document discloses a structure in which a water heating space and a humidifying space are connected to each other. This causes a problem that the water cannot be completely sterilized when the water heating temperature is maintained below a set temperature in consideration of an ultrasonic vibrator. In addition, when water is heated to sterilize and sent to the ultrasonic vibrator, there is a problem that the ultrasonic vibrator may malfunction. That is, in the case of prior document, there is difficulty in completely sterilizing and humidifying water.
In addition, since a separate water level control device is not provided in a space for heating and a space for humidification, there is a problem in that it is difficult to directly control the water level inside a heating water tank or a humidifying water tank. In addition, since a pipe that supplies water from a water tank to the heating water tank is located below the water tank and the heating water tank, there is a problem that residual water occurs inside the pipe before and after use.

A second groove 204b, which is recessed upward in the direction in which the heating water tank 170 is disposed, is formed in the lower end of the exhaust pipe 202.
The first groove 204a and the second groove 204b may allow the air discharged from the air supply pipe 140 to easily flow into the exhaust pipe 202. The first groove 204a and the second groove 204b may allow humidified air discharged from the heating water tank 170 to easily flow into the exhaust pipe 202.
The first groove 204a and the second groove 204b may allow air flowing from the air supply pipe 140 to flow into the exhaust pipe 202, even if the humidifying water tank 130 is filled with water at a certain level. The first groove 204a and the second groove 204b may allow air flowing from the air flow pipe 230 to flow into the exhaust pipe 202, even if the humidifying water tank 130 is filled with water at a certain level. The first groove 204a and the second groove 204b are disposed in opposite directions.
The lower hole 202a is formed in the lower end of the exhaust pipe 202, and the upper hole 202b is formed in the upper end. Accordingly, humidified air generated in the humidifying chamber 130a may flow into the lower hole 202a and flow into the upper hole 202b. In the case of humidified air, due to its rising nature, it may flow from the lower hole 202a to the upper hole 202b and flow into the first discharge passage 74. However, condensed water generated in the first discharge passage 74 may flow into the upper hole 202b of the exhaust pipe 202 and flow into the lower hole 202a. Accordingly, condensed water generated in the first discharge passage 74 may flow into the humidifying chamber 130a.
A middle hole 202c may be formed in the exhaust pipe 202, in one side facing a flow pipe outlet 234 of the air flow pipe 230 of the second connector 220 described below. The middle hole 202c is disposed between the lower hole 202a and the upper hole 202b. The middle hole 202c may be disposed in the area where the humidifying chamber 130a is formed. The middle hole 202c may be disposed to face the flow pipe outlet 234 of the air flow pipe 230. Accordingly, the air flowing in the heating water tank 170 through the air flow pipe 230 may flow into the exhaust pipe 202 through the middle hole 202c. Water vapor discharged from the heating chamber 170a through the air flow pipe 230 may flow to the exhaust pipe 202 through the middle hole 202c or the lower hole 202a and then flow into the first discharge passage 74.

The first connecting plate 208 may have a shape bent upward from the first plate 206. The first connecting plate 208 may have a shape corresponding to the upper side of the air supply pipe 140.
Accordingly, the air flowing through the air supply pipe 140 may flow into the inner space of the humidifying water tank wall 132 along the first connecting plate 208. However, the air supplied through the air supply pipe 140 may flow downward inside the humidifying water tank wall 132 through the exhaust pipe 202 and flow to the exhaust pipe 202. That is, the air supplied through the air supply pipe 140 may flow inside the humidifying water tank wall 132 and flow to the exhaust pipe 202 together with the humidified air generated inside the humidifying water tank 130. This may increase the amount of humidified air flowing through the exhaust pipe 202.
The first connector 200 includes a second connecting plate 210 disposed in the upper side of the air flow pipe 230 of the second connector 220 described below. The second connecting plate 210 may have a shape bent upward from the first plate 206. The second connecting plate 210 may have a shape corresponding to the upper surface of the air flow pipe 230.
Accordingly, the air flowing through the air flow pipe 230 may flow into the inner space of the humidifying water tank wall 132 along the second connecting plate 210. The air supplied through the air flow pipe 230 may flow into the middle hole 202c of the exhaust pipe 202. In addition, the air supplied through the air flow pipe 230 may flow inside the humidifying chamber 130a and flow into the lower hole 202a of the exhaust pipe 202.

The lower protrusion 212 may have a structure that protrudes downward from the first plate 206. The lower protrusion 212 may be disposed in contact with the humidifying water tank wall 132 of the humidifying water tank 130. The lower protrusion 212 contacts the inside of the humidifying water tank wall 132, so that the disposition of the first connector 200 disposed in the upper side of the humidifying water tank 130 can be fixed.
The first connector 200 may include a blocking wall 214. The blocking wall 214 extends downward from the first plate 206. The blocking wall 214 may be disposed in the area where the water level sensor 160 is disposed. The blocking wall 214 has a bending structure, and has one end and the other end that are disposed in contact with the inside of the humidifying water tank wall 132.
The length 214L of the blocking wall 214 protruding downward from the first plate 206 may be longer than the length 202L of the exhaust pipe 202 protruding downward from the first plate 206. Accordingly, the blocking wall 214 may minimize changes in the water level vibrated by the ultrasonic vibrator 162a, 162b in the area where the water level sensor 160 is disposed.

In accordance with an aspect of the present disclosure, a humidifier includes: a water tank for storing water; a heating water tank which is disposed below the water tank, and heats water supplied from the water tank; a humidifying water tank which is disposed below the water tank, and generates humidified air by using water supplied from the heating water tank; a connection pipe which connects the heating water tank and the humidifying water tank so that water stored in the heating water tank flows to the humidifying water tank; and a floating valve which is disposed in the heating water tank and controls a water level of the heating water tank, wherein a water level of the humidifying water tank is controlled according to a disposition of the floating valve, thereby controlling the water levels of the humidifying water tank and the heating water tank by a floating valve disposed in the heating water tank.
The connection pipe is disposed below the floating valve, so that when the heating water tank is filled with water at a certain level, water can be supplied to the humidifying water tank.
A water discharge hole is formed in an area to which the connection pipe is connected, in the heating water tank, a water inlet hole is formed in an area connected to the connection pipe, in the humidifying water tank, and the water discharge hole and the water inlet hole are disposed lower than the lowest location of the floating valve, so that when water is supplied to the heating water tank, water may flow into the humidifying water tank before the floating valve moves.
The water inlet hole is disposed at the same level as or lower than the water discharge hole, so that when a certain level of water is supplied to the heating water tank, water can flow into the humidifying water tank.
The water discharge hole is disposed spaced apart upwards at a certain gap from a lower end of the heating water tank, so that heated water can be supplied from the heating water tank.
An exhaust pipe for discharging humidified air existing in the humidifying water tank is disposed in the humidifying water tank, and a lower end of the exhaust pipe is disposed higher than an upper end of the floating valve.
Since the water level is formed between the lower end and the upper end of the floating valve, a gap may be formed from the lower end of the exhaust pipe even if the water level in the humidifying water tank is at the highest level.
Even at the highest water level of the humidifying water tank, humidified air generated in the humidifying water tank can flow through the exhaust pipe.
When the floating valve is disposed at the highest movable location, a level of water stored in the humidifying water tank is lower than the lower end of the exhaust pipe, so that humidified air generated in the humidifying water tank can flow through the exhaust pipe even at the highest water level of the humidifying water tank.
A height of the connection pipe is inclined to decrease as it progresses from the heating chamber to the humidification chamber, so that water stored in the heating water tank may flow into the humidifying water tank.
A connection pipe valve that opens and closes an internal passage of the connection pipe is disposed in the connection pipe, thereby controlling the timing of supplying water stored in the heating water tank to the humidifying water tank.
The humidifier further includes a temperature sensor which is disposed in one side of the heating chamber, and detects a temperature inside the heating chamber, wherein the connection pipe valve is opened when water temperature inside the heating chamber detected by the temperature sensor is a set temperature or higher, so that water sterilized by heating can be supplied to the humidifying water tank.
A height at which the temperature sensor is disposed is lower than a height of the water discharge hole that is formed to allow water in the heating water tank to flow into the connection pipe, so that the temperature of the water can be detected even when water is supplied to the water discharge hole.
The heating water tank includes: an outer wall which forms a space where water is stored; and an inner wall which forms a space, inside the outer wall, where the floating valve is disposed, wherein water supplied from the water tank flows to the outer wall through the inner wall.
The heating water tank further comprises a heater which is disposed in a lower portion of the outer wall and heats water stored inside the outer wall, wherein the inner wall is disposed to be spaced upward from the heater.
The floating valve is disposed to be movable in an up-down direction inside the inner wall, so that the floating valve can move stably.
The inner wall includes: an inner peripheral wall which protrudes to the inside of the outer wall and forms a space in which the floating valve is disposed; and an inner lower wall which restricts a downward movement of the floating valve, wherein a communication hole is formed, in the inner lower wall, to communicate the inside of the inner wall and the inside of the outer wall, so that the movement of the floating valve is restricted by the inner wall, and the water supplied to the inner wall can be supplied to the inside of the outer wall through the communication hole.
The humidifier further includes a water supply tank in which a water supply hole is formed to supply water supplied from the water tank to the heating water tank, wherein the water supply tank is disposed in an upper side of the inner wall, so that a floating valve can control the water supplied to the water supply tank.
The floating valve opens and closes the water supply hole according to water level of the humidifying water tank.
In accordance with another aspect of the present disclosure, a humidifier includes: a heating water tank which forms a heating chamber for heating water therein; a humidifying water tank which is disposed in one side of the heating water tank, is connected to the heating water tank, and generates humidified air by using water supplied from the heating water tank; and a floating valve which is disposed to be movable in an up-down direction in the heating water tank, and controls a water level of the heating water tank, wherein a water level of the humidifying water tank is controlled according to a disposition of the floating valve, so that the water levels of the humidifying water tank and the heating water tank can be controlled by a floating valve disposed in the heating water tank.
In accordance with another aspect of the present disclosure, a humidifier includes: a heating water tank which forms a heating chamber for heating water therein; a humidifying water tank which is disposed in one side of the heating water tank, is connected to the heating water tank, and generates humidified air by using water supplied from the heating water tank; a connection pipe which sends water stored in the heating water tank to the humidifying water tank; an air flow pipe which is connected to allow a humidified air generated in the heating water tank and a humidified air generated in the humidifying water tank to flow; and a floating valve which is disposed to be movable in an up-down direction in the heating water tank, and controls a water level of the heating water tank and a water level of the humidifying water tank, wherein the floating valve is disposed to be movable in an up-down direction between the connection pipe and the air flow pipe, so that the water level can be controlled between the connection pipe through which water flows and the air flow pipe through which air flows.
In accordance with another aspect of the present disclosure, a humidifier includes: a water tank for storing water; a heating water tank which is disposed below the water tank, and heats water supplied from the water tank; a humidifying water tank which is disposed below the water tank, and generates humidified air by using water supplied from the heating water tank; a connection pipe which connects the heating water tank and the humidifying water tank so that water stored in the heating water tank flows into the humidifying water tank; a floating valve which is disposed in the heating water tank, and controls a water level of the heating water tank; and an exhaust pipe which discharges the humidified air existing in the humidifying water tank to the outside, wherein a lower end portion of the exhaust pipe is located inside the humidifying water tank, wherein the floating valve maintains a water level of the humidifying water tank at a certain gap below the lower end portion of the exhaust pipe located inside the humidifying water tank, thereby minimizing the disturbance of the humidified air discharged to the humidifying water tank by the water stored in the humidifying water tank.

These modifications should not be individually understood from the technical concept or scope of the present disclosure.
It will be understood that when an element or layer is referred to as being “on” another element or layer, the element or layer can be directly on another element or layer or intervening elements or layers. In contrast, when an element is referred to as being “directly on” another element or layer, there are no intervening elements or layers present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
It will be understood that, although the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section could be termed a second element, component, region, layer or section without departing from the teachings of the present invention.
Spatially relative terms, such as “lower”, “upper” and the like, may be used herein for ease of description to describe the relationship of one element or feature to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “lower” relative to other elements or features would then be oriented “upper” relative to the other elements or features. Thus, the exemplary term “lower” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Any reference in this specification to “one embodiment,” “an embodiment,” “example embodiment,” etc., means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with any embodiment, it is submitted that it is within the purview of one skilled in the art to effect such feature, structure, or characteristic in connection with other ones of the embodiments.
Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More particularly, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims.
