This application claims priority to Korean Patent Application No. 10-2022-0177798, filed Dec. 19, 2022, whose entire disclosures are hereby incorporated by reference.
The present disclosure relates to a humidifier.
A humidifier is an appliance that releases humidified air containing large amounts of moisture by vaporizing water. The humidifier is able to create humidified air by vaporizing water by natural evaporation, evaporation by heating, ultrasonic vibration, etc.
Unlike natural evaporative humidifiers and heated evaporative humidifiers, ultrasonic humidifiers produce a mist by atomizing stored water via ultrasonic vibration. The mist produced by ultrasonic vibration is tiny droplets of water which themselves tend to sink down by gravitational force, making it difficult to smoothly supply them to an indoor space.
The “ultrasonic humidifier” disclosed in Korean Patent Registration No. 2253576 includes: a lower housing; an upper housing spaced upward from the lower housing to form an air inlet flow path, and having an outlet section with an open top; an annular water reservoir provided inside the upper housing, for storing water; a blower fan disposed in a hollow portion in the annular water reservoir; and an inner cover disposed above the blower fan, that covers the hollow portion in the annular water reservoir, wherein a discharge flow path is formed between the inner cover and an inner surface of the upper housing, which communicates with the outlet section.
The conventional humidifier is problematic in that it requires a complex humidification flow path in order to create a flow of humidified air by which an air stream formed by the blower fan passes through the water surface in the water reservoir and is discharged to the outlet section, together with mist.
Moreover, due to the complex humidification flow path, the structural design becomes complex, and the user will have difficulty cleaning the inside of the humidifier.
Another drawback is that, due to the complex humidification flow path, an air stream formed by the blower fan is not discharged via the water surface in the water reservoir, forming eddy currents swirling in the water reservoir. This will result in failing to supply the mist in the water reservoir smoothly into an indoor space through the outlet section.
Besides, the water stored in the water reservoir is immediately atomized without sterilization, which may lead to contamination of the indoor space and be potentially harmful to the health of people in the indoor space.

A humidifier 1 will be described with reference to
The humidifier 1 includes a case 10 forming its exterior. The case 10 may extend vertically. Mist may be produced in the case 10. A flow path through mist flows may be formed in the case 10.
An inlet 20 for drawing in air is formed in the case 10. The inlet 20 may be formed below the case 10. The inlet 20 may be formed along the periphery of the case 10. Indoor air may be drawn into the case 10 through the inlet 20. The drawn-in indoor air may flow upward by a blower fan 24 (see
A outlet 50 through which humidified air is discharged is formed in the case 10. The outlet 50 has an open top at the case 10. The outlet 50 may be formed through the top of the case 10 and have an open top. Indoor air admitted to the inside of the case 10 through the inlet 20 may flow upward and be discharged through the upwardly open outlet, and mist produced in the case 10 may be discharged through the outlet 50, along with the indoor air.
The inlet 20 and outlet 50 formed in the case 10 may be spaced apart from each other. For example, the inlet 20 may be formed in a lower part of the case 10, and the outlet 50 may be formed in an upper part of the case 10. Thus, air returning may be prevented by spacing an incoming air stream and an outgoing air stream apart from each other.
The outlet 50 may be annular. As the outlet 50 is annular, the produced mist may be distributed uniformly in all directions of the indoor space.
The outlet 50 may include an inner outlet 54 and an outer outlet 56.
The inner outlet 54 may be spaced apart from the center of the top of the case 10. The inner outlet 54 may extend along the periphery of the case 10. For example, the inner outlet 54 may be an annular inner outlet 54 that extends circumferentially along the periphery of a cylindrical case 10.
The outer outlet 56 may be formed along the periphery of the top of the case 10. For example, the outer outlet 56 may be an annular outer outlet 56 formed along the periphery of the top of the cylindrical case 10. The annular outer outlet 56 may be radially spaced from the annular inner outlet 54.
The inner outlet 54 and the outer outlet 56 may be spaced apart from each other. For example, the outer outlet 56 may be radially spaced from the inner outlet 54. Since the inner outlet 54 and the outer outlet 56 are spaced apart from each other, air discharged through the inner outlet 54 and air discharged through the outer outlet 56 may be separated from each other. For example, humidified air discharged from the inner outlet 54 and filtered air discharged from the outer outlet 56 may be discharged separately. The humidified air may be humid air containing mist, and the filtered air may be dry air not containing mist. Hereinafter, the term “humidified air” may refer to air containing mist.
The case 10 may include a discharge assembly 5 where the outlet 50 is formed. The outlet 50 may be open through the top of the discharge assembly 5. For example, air admitted to the underside of the discharge assembly 5 may pass through the discharge assembly 5 through the outlet 50 and exit through the top of the discharge assembly 50.
The discharge assembly 5 may guide an outgoing air stream.
The discharge assembly 5 may be disposed above a humidification reservoir 33. Mist produced in the humidification reservoir 33 may ascend, and the ascending mist may pass through the outlet 50 formed in the discharge assembly 5 and be supplied to the indoor space.

Since the annular outer outlet 56 is separated radially from the annular inner outlet 54 by the annular discharge panel 55, the humidified air discharged from the inner outlet 54 and the filtered air discharged from the outer outlet 56 may be discharged separately.
A tank cap 42 may be disposed at the top of the discharge assembly 5. The tank cap 42 may be attached to or detached from the discharge assembly 5. The tank cap 42 may cover the open top of the tank 4.
The tank cap 42 may be disposed at the center of the top of the discharge assembly 5. The tank cap 42 may be spaced inward from the inner outlet 54. The inner outlet 54 may be spaced radially from the tank cap 42, and may be formed circumferentially along the periphery of the tank cap 42. For example, the outer outlet 56, extending circumferentially along the periphery, and the inner outlet 54, spaced radially from the outer outlet 56 and extending circumferentially, may be formed at the top of the cylindrical discharge assembly 5, the discharge panel 55 may be disposed between the outer outlet 56 and the inner outlet 54, and the tank cap 42 may be disposed at the center of the top of the discharge assembly 5.

Part of the ascending air stream formed in the blower assembly 2 may be discharged through the inner outlet 54 formed in the discharge assembly 5, and the rest of the ascending air stream formed in the blower assembly 2 may be discharged through the outer outlet 56. Air containing part of the ascending air stream discharged through the inner outlet 54 and mist produced in the humidification reservoir 33 may be humidified air. The rest of the ascending air stream may be filtered air.

The ascending air stream formed in the blower assembly 2 may flow between the guide shell 6 and the humidification reservoir 33. A blower flow path 330 may be formed between the guide shell 6 and the humidification reservoir 33. For example, a blower flow path 330 whose cross-section is annular may be formed between an inner peripheral surface of the guide shell 6 and an outer peripheral surface of the humidification reservoir 33. The blower flow path 330 may extend along the inner periphery of the guide shell 6. The blower flow path 330 may extend along the outer periphery of the humidification reservoir 33.
The guide shell 6 may form a discharge flow path 40 inside. The discharge flow path 40 may be positioned above the humidification assembly 3. The discharge flow path 40 may be positioned below the discharge assembly 5. The discharge flow path 40 may communicate with the outlet 50 formed in the discharge assembly 5. The mist produced in the humidification assembly 3 may flow upward through the discharge flow path 40, and be discharged through the outlet 50 formed in the discharge assembly 5 and supplied to the indoor space.
The humidifier 1 may include a tank 4 for storing water. The tank 4 may be disposed inside the case 10. The tank 4 may be attached to or detached from the case 10.
The tank 4 may be open at the top. The tank cap 42 may cover the open top of the tank 4. The tank cap 42 may be attached to or be detached from the tank 4.
The tank 4 may have the shape of a cylinder that extends upward. The tank 4 may be spaced inward from the guide shell 6. The discharge flow path 40 may be formed between the tank 4 and the guide shell 6. For example, a discharge flow path 40 whose cross-section is annular may be formed between a cylindrical tank 4 and a cylindrical guide shell 6. The outlet 50 may be adjacent to an upper end of the tank 4.
By disposing the tank 4 at the center of the discharge flow path 40, humidified air may flow upward smoothly within the case 10. The tank 4 may guide the humidified air within the case 10 upward. By disposing the tank 4 at the center of the discharge flow path 40, it is possible to reduce eddy currents which cause the humidified air to swirl in the discharge flow path 40 within the case 10.
The tank 4 may be disposed above the humidification reservoir 33. The tank may correspond in position to the center of the humidification reservoir. For example, the tank may extend upward from the center of the humidification reservoir. The tank may guide the mist produced in the humidification reservoir upward.
Referring to
The blower assembly 2 may form an ascending air stream. The ascending air stream may flow within the case 10.
A bypass guide 23 may be disposed above the blower assembly 2. The bypass guide 23 may guide an ascending air stream blown from the blower assembly 2. The ascending air stream blown from the blower assembly 2 may rise along the outer periphery of the humidification assembly 3. The blower flow path 330 may be formed between the humidification assembly 3 and the guide shell 6, and the ascending air stream blown from the blower assembly 2 may flow and rise through the blower flow path 330.
The humidifier 1 may include a humidifier assembly 3 disposed inside the case 10. The humidification assembly 3 produces mist. The humidification assembly 3 may include a humidification reservoir 33 that produces mist. The humidification assembly 3 may store water for producing mist.
The humidification assembly 3 may be open at the top. The mist produced in the humidification assembly 3 may flow to the open top of the humidification assembly 3.
The humidification assembly 3 may be disposed above the blower assembly 3. The ascending air stream blown from the blower assembly 2 may cause the mist produced in the humidification assembly 3 to rise. That is, the ascending air stream blown from the blower assembly 2 may flow up along the outer periphery of the humidification assembly 3, and, may flow up above the humidification assembly 3.
The center axis CA of the humidification assembly may correspond in position to the position of the center axis CA of the blower assembly 2.
The guide shell 6 may have the shape of a cylinder that extends upward. The guide shell 6 may form the blower flow path. For example, the blower flow path 330 may be formed between the inner periphery of the guide shell 6 and the outer periphery of the humidification reservoir 33.

The humidifier 1 may include a diversion guide 7 for guiding an ascending air stream.
The diversion guide 7 may divide an ascending air stream. For example, the diversion guide 7 may divide an ascending air stream passing through the blower flow path 330 into an inner discharge flow path 70 and an outer discharge flow path 60. That is, part of the ascending air stream passing through the blower flow path 330 may enter the inner discharge flow path 70 by the diversion guide 7, and the rest of the ascending air stream passing through the blower flow path 330 may enter the outer discharge flow path 60.
The diversion guide 7 may divert the flow of an ascending air stream. For example, the diversion guide 7 may divert the flow of an ascending air stream passing through the blower flow path 330 from upward to diagonal. By means of the diversion guide 7, the ascending air stream passing through the blower flow path 330 may be diverted from a direction in which it flows up along the outer periphery of the humidification assembly 3 to a direction in which it flows up above the humidification assembly 3. That is, the diversion guide 7 may redirect the flow of an ascending air stream to a lateral direction. Since the diversion guide 7 directs an ascending air stream to flow up above the humidification assembly 3, the mist produced in the humidification assembly 3 may flow much further upward.
The diversion guide 7 is disposed on the top of the humidification assembly 3. The diversion guide 7 may be seated on the top of the humidification assembly 3. A lower end of the diversion guide 7 may be inserted into the open top of the humidification reservoir 33, and the diversion guide 7 may be seated on the humidification reservoir 33.

As such, an ascending air stream flowing up along the outer periphery of the humidification reservoir 33 may enter the inner discharge flow path 70 through the guide opening 72. Alternatively, the ascending air stream flowing up along the outer periphery of the humidification reservoir 33 may be diverted to a direction in which it flows upward of the humidification reservoir 33 by means of the guide opening 72

For example, the guide wall 74 may have the shape of a cylinder that extends upward.
The center axis CA of the guide wall 74 may correspond in position to the center axis CA of the blower assembly 2, the center axis CA of the guide shell 6, and/or the center axis CA of the humidification assembly 3.
The guide wall 74 may be spaced inward from the case 10. The guide wall 74 may be spaced inward from the guide shell 6. A flow path may be formed between the guide wall 74 and the guide shell 6. For example, an annular outer discharge flow path 60 may be formed between a cylindrical guide wall 74 and a cylindrical guide shell 6.
The inner discharge flow path 70 may be formed inside the guide wall 74.
The outer periphery of the guide wall 74 may be positioned outward from the outer periphery of the humidification reservoir 33. That is, the radius of the guide wall 74 may be larger than the radius of the humidification reservoir 33. Thus, the mist produced in the humidification reservoir 33 may flow upward inside the guide wall 74. Also, the guide opening 72 may keep the mist produced in the humidification reservoir 33 from flowing out to the outer discharge flow path 60.
The humidifier 1 may include a tank 4 for storing water. The tank 4 may supply the stored water to the humidification reservoir 33.
The tank 4 may be disposed inside a case. The tank 4 may be disposed above the humidification reservoir 33. The tank 4 may be disposed above the humidification reservoir 33 and extend upward. The upwardly extending tank 4 may guide the mist produced in the humidification reservoir 33 upward. The upwardly extending tank 4 may form the discharge flow path 40. For example, the discharge flow path 40 may be formed between an outer peripheral surface of the tank 4 and an inner peripheral surface of the guide shell 6. Moreover, an inner discharge flow path 70 whose cross-section is annular may be formed between the outer peripheral surface of the tank 4 and an inner peripheral surface of the guide wall 74.
The tank 4 may guide the mist produced in the humidification reservoir 33 to the outlet 50. For example, the tank 4 may guide the mist produced in the humidification reservoir 33 to flow upward and be discharged through the inner outlet 54.
The tank 4 may be attached to and detached from the case 10. The tank 4 may be open at the top so as to be filled with water. The tank 4 may be disposed in an inner upper part of the case 10.

An annular discharge flow path 40 may be formed between a cylindrical tank 4 and a cylindrical guide shell 6. An annular inner discharge flow path 70 may be formed between a cylindrical tank 4 and a cylindrical guide wall 74.
The center axis CA of the tank 4 may correspond in position to the center axis CA of the blower assembly 2, the center axis CA of the guide shell 6, the center axis CA of the guide wall 74, and/or the center axis CA of the humidification assembly 3.
The discharge assembly 5 may be disposed above the tank 4. The discharge assembly 5 may be inserted through the open top of the guide shell 6. The discharge assembly 5 may form an upper surface of the case 10.

For example, an upper end of the tapered flow path 58 may form the outlet 50, and a lower end of the tapered flow path 58 may be connected to the discharge flow path 40. Since the surface of the tapered flow path 58 becomes smaller from upstream to downstream, the density of the humidified air to be discharged may increase.
Therefore, the user is able to see the humidifier's operating state easily and visually from a long distance.
The outer discharge guide 52b and the inner discharge guide 52a may form the tapered flow path 58. The outer discharge guide 52b may be slanted inwardly upward.
