Description

TECHNICAL FIELD

The present disclosure relates to an easy-to-clean heated humidifier and, more particularly, to an easy-to-clean heated humidifier having a water container that may be separated from the humidifier and easily cleaned.

BACKGROUND ART

In general, a humidifier is a device that increases humidity in a room by generating steam. In winter when humidity is decreased significantly, the humidifier is used to artificially generate steam to create a comfortable indoor environment. Recently, as the use of heaters in homes and offices is sharply increased, the demand for the humidifier is gradually increased.

The humidifier is classified into a heated humidifier and an ultrasonic humidifier according to humidification methods. Specifically, the heated humidifier is operated by a method of naturally spraying steam generated by heating water in a water container to a predetermined temperature, and the ultrasonic humidifier is operated by a method of spraying fine water particles by vibrating water in a water container with ultrasonic waves.

The heated humidifier may kill bacteria contained in water by heating the water, but has a small amount of humidification because the heated humidifier humidifies using vaporized steam. However, the ultrasonic humidifier spraying fine water particles generated by ultrasonic waves has an amount of humidification relatively larger than the amount of humidification of the heated humidifier, but the ultrasonic humidifier without heating process by the heating means cannot sterilize water therein.

In the ultrasonic humidifier, water is supplied to a vibrator constituting the ultrasonic humidifier to spray fine water particles with ultrasonic waves, and the vibrator vibrates the supplied water to generate the fine water particles.

The ultrasonic humidifier spraying the fine water particles by using ultrasonic waves has an environment in which bacteria in the water can easily grow. Therefore, in order to solve the above problem, various ultrasonic humidifiers that can easily clean the water container have been released on the market.

On the other hand, in the case of the heated humidifier that can kill bacteria in water, heated humidifiers that can clean the water container are less common in the market than ultrasonic humidifiers. However, the inside of the water container may be contaminated due to floating matter in the water in the heated humidifier, so the heated humidifier also needs a method for easily cleaning the inside thereof.

The cover 140 includes the spraying port 150 as described above. A steam transport pipe is provided in the cover 140 to supply steam to the spraying port 150.

The main body 120 is located at a lower end of the cover 140, and includes the operation means 130 adjusting an amount of steam sprayed through the spraying port 150 of the cover 140. As described above, the operation means 130 may be applied to the main body as various methods such as a dial or a button.

The main body 120 includes an outer casing 121 and an inner casing, and the inner casing includes a preheating casing 122 and a heating casing 123. The main body 120 may consist of two areas of the outer casing and the heating casing. Hereinafter, for convenience of description, the main body will be described as including the outer casing, the preheating casing, and the heating casing, but the main body may consist of four areas rather than the three areas, if necessary.

The preheating casing 122 is located inside the outer casing 121, and the heating casing 123 is located inside the preheating casing 122. Adding additional descriptions, the main body 120 is configured such that the outer casing 121, the preheating casing 122, and the heating casing 123 are arranged in order from an outer portion of the main body 120. Shapes and structures of the outer casing 121, the preheating casing 122, and the heating casing 123 will be described later.

In the easy-to-clean heated humidifier proposed by the present disclosure, the preheating casing and the heating casing constituting the main body may be separated from the main body. A user can remove the preheating casing and the heating casing from the outer casing that is a portion storing water and simply perform cleaning. In detail, the user can separate the preheating casing and the heating casing from the main body for cleaning, and can easily clean the preheating casing and the heating casing after separating them, and can simply clean the inside of the outer casing in a state without the preheating casing and the heating casing.

FIG. 3 is a view showing the outer casing according to the embodiment of the present disclosure. Hereinafter, the structure and shape of the outer casing according to the embodiment of the present disclosure will be described in detail with reference to FIG. 3.

The outer casing 121 has a hollow cylinder shape, and an upper end thereof is open and a lower surface is partially open at a center portion thereof. The rest of the lower surface of the outer casing 121 except for the open center portion is closed. The outer casing 121 may be preferably formed to be integrated with the main body into a single body, but the outer casing 121 may also be separated from the main body.

Except for the center portion of the lower surface of the outer casing 121, the rest of the lower surface thereof is closed, and an extended portion 121b extended to a predetermined length in a vertical direction (height direction of the outer casing) is formed at an end of the lower surface.

The extended portion 121b includes a first extended portion 121b-1 extended downward from a lower end of the lower surface of the outer casing to a predetermined length in the vertical direction and a second extended portion 121b-2 extended downward from the first extended portion 121b-1 to a predetermined length while being partially bent. The second extended portion 121b-2 has a diameter relatively smaller than a diameter of the first extended portion 121b-1.

The lower surface of the outer casing 121 has protrusions 121c inserted into holes formed on a lower main body so as to be coupled to the lower main body. The protrusions 121c formed on the lower surface of the outer casing 121 are inserted into the holes formed on the main body, so that the outer casing may maintain a fixed state to the main body.

Hereinafter, a bottom surface structure of the outer casing 121 will be described. The outer casing 121 has two gaps at a bottom surface therein. The gaps are formed at different distances from the center of the bottom surface in the outer casing. A first gap 121a-1 is formed on the first extended portion 121b-1 provided at a relatively long distance from the center of the bottom surface in the outer casing, and a second gap 121a-2 is formed on the second extended portion 121b-2 provided at a relatively short distance therefrom. A lower end of the preheating casing is in close contact with the first extended portion 121b-1 having the first gap 121d-1, and a lower end of the heating casing is in close contact with the second extended portion 121a-2 having the second gap 121a-2.

FIG. 4A and 4B are views showing a structure of the preheating casing according to the embodiment of the present disclosure. Hereinafter, the structure and shape of the preheating casing according to the embodiment of the present disclosure will be described in detail with reference to FIGS. 4A and 4B.

As shown in FIGS. 4A and 4B, the preheating casing 122 has a cylinder shape. In particular, the preheating casing 122 has a shape with open upper and lower surfaces.

The lower end of the preheating casing 122 is in close contact with the first extended portion formed on the lower surface of the outer casing 121 to prevent water stored in a space between the preheating casing 122 and the outer casing 121 from being introduced into the preheating casing 122. However, when the lower end of the preheating casing 122 is in close contact with the first extended portion formed on the outer casing 121, the water stored in the space between the preheating casing 122 and the outer casing 121 may be introduced into the preheating casing 122 through the first gap formed on the outer casing 121. Only through the first gap formed on the first extended portion, the water stored in the space between the preheating casing 122 and the outer casing 121 is introduced into the preheating casing 122.

FIG. 5 is a view showing a structure of the heating casing according to the embodiment of the present disclosure. Hereinafter, the structure and shape of the heating casing according to the embodiment of the present disclosure will be described in detail with reference to FIG. 5.

Referring to FIG. 5, like the shape of the preheating casing 122, the heating casing 123 has a cylinder shape, and an upper end and a lower surface thereof are open. In the present disclosure, steam generated in the heating casing 123 is sprayed outward by its own pressure.

In detail, when water heated by the heating means is changed into steam, a volume of the water is increased in the heating casing 123, and high pressure is generated due to the increased volume. The high pressure allows the steam to be sprayed to the outside of the humidifier.

The lower end of the heating casing 123 is in close contact with the second extended portion provided on the bottom surface of the outer casing 121 to prevent water stored in a space between the heating casing 123 and the preheating casing 122 from being introduced into the heating casing 123. However, in the state in which the lower end of the heating casing 123 is in close contact with the second extended portion provided on the outer casing 121, the water stored in the space between the heating casing 123 and the preheating casing 122 is introduced into the heating casing 123 through the second gap formed on the outer casing 121. In other words, the water stored in the space between the heating casing 123 and the preheating casing 122 is introduced into the heating casing 123 only through the second gap formed on the second extended portion.

The heating means 115 is provided at an upper end the lower main body, i.e. the lower surface of the heating casing 123, and the water introduced into the heating casing 123 is heated by the heating means and is changed into steam. Preferably, an amount of water introduced into the heating casing 123 through the second gap is supplied to the same level as an amount of steam sprayed by the heating means 115, so that the water in the heating casing 123 may be maintained at a predetermined level.

The second gap is formed at a portion lower than the lower surface of the outer casing 121, i.e. a minimum water level of the heating casing 123. In other words, the second gap is formed at a position lower than the lower surface of the outer casing 121 located outside the preheating casing 122. In addition, a portion between the second gap and the spraying port is sealed to allow the steam generated in the heating casing 123 to be sprayed through the spraying port. A lower end portion of the heating casing may have a shape protruding outward at a predetermined length.

The present disclosure does not propose a water container having a single structure, but a water container having at least a double structure consisting of the outer casing, the preheating casing, and the heating casing, as described above. As the present disclosure proposes the water container having at least double structure, the heating means 115 may reduce the time required to spray steam by heating only a portion of water stored in the heating casing instead of the whole water stored in the main body.

The water stored in the space between the preheating casing and the heating casing has been heated by being transmitted with a portion of heat from the water stored in the heating casing. Therefore, when the water is introduced into the heating casing, the time required to heat the water introduced into the heating casing and spraying steam changed from the water may be reduced.

In addition, the temperature of the water stored in the space between the outer casing and the preheating casing is lowered than the temperature of the water stored in the space between the preheating casing and the heating casing. Therefore, even when the user touches an outer portion of the outer casing, the user would not be burned.

In particular, the present disclosure has the water container consisting of a plurality of structures, so noise generated when the water in the heating casing is heated may be prevented.

Furthermore, the present disclosure may be preferably configured to arrange the first gap and the second gap not on the same radial circumference. Therefore, the outer casing has the first gap and the second gap formed on different locations thereof, and the first gap and the second gap are preferably located at opposite sides to each other.

FIG. 6 is a view showing a sectional structure of the main body according to the embodiment of the present disclosure. Hereinafter, the sectional structure of the main body according to the embodiment of the present disclosure will be described in detail with reference to FIG. 6. In particular, FIG. 6 will be described with a focus on the structures of the outer casing, the preheating casing, and the heating casing.

As described above, the outer casing 121 is formed in a cylinder, and the lower surface thereof is closed except for the open center portion of the lower surface. Hereinbelow, a lower structure of the outer casing 121 will be described in detail. The lower surface of the outer casing includes a bottom portion 121a, the first extended portion 121b-1, and the second extended portion 121b-2. The bottom portion 121a is a remaining portion of the outer casing except for the open center portion thereof, and the first extended portion 121b-1 is provided by being vertically extended downward from the bottom portion 121a to the predetermined length and the second extended portion 121b-2 is provided by being bent from the first extended portion 121b-1 and extended downward to the predetermined length. As described above, the lower surface of the outer casing proposed by the present disclosure includes the bottom portion 121a, the first extended portion 121b-1, and the second extended portion 121b-2. The diameter of the second extended portion 121b-2 is smaller than the diameter of the first extended portion 121b-1.

The preheating casing 122 is formed in a cylinder with an open lower surface. The lower end of the preheating casing 122 is inserted in close contact with the first extended portion 121b-1 of the outer casing 121. In detail, the lower end of the preheating casing 122 has a protrusion 122a extended outward to a predetermined length, and the protrusion 122a is inserted into the lower end of the outer casing 121 while being in close contact with an upper end of the first extended portion 121b-1.

As described above, the heating casing 123 has a cylinder shape with an open lower surface. In addition, the lower end of the heating casing 123 has a protrusion 123a extended outward to a predetermined length, and the protrusion 123a is inserted into the lower end of the outer casing 121 while being in close contact with an upper end of the second extended portion 121b-2. In detail, in the present disclosure, while the heating casing 123 is inserted in the outer casing 121, the preheating casing 122 is inserted into a space between the outer casing 121 and the heating casing 123.

The present disclosure is configured to move water from an upper main body through the gaps, but the present disclosure is not limited thereto, and may be configured to move the water from the upper main body through a groove or other methods.

The present disclosure describes the humidifier, but is not limited thereto. Various devices using steam may use the outer casing, the preheating casing, and the heating casing proposed by the present disclosure to generate steam and use the generated steam. In this case, variously shaped discharge means discharging steam are provided in the device using steam.
