Dual structure humidifier with noise reduction function {DUAL STRUCTURE HUMIDIFIER WITH NOISE REDUCTION FUNCTION}

This specification relates to a dual structure humidifier, and more specifically, to a dual structure floating humidifier including a noise reduction function.

Humidifiers are a representative seasonal home appliance that is mainly used during the dry winter months. However, recently, humidifiers are used in spring and fall when there is a lot of fine dust due to the atmospheric environment, and even in summer when air conditioners are used, to prevent indoor humidity from dropping excessively due to air conditioner coolant.

In this way, humidifiers have become a representative home appliance used all year round. However, the humidifier generates various noises inside the humidifier, such as noise generated in the process of generating fine water droplets, noise generated when the blowing fan rotates, and noise generated by fine vibration.

Typically, humidifiers are placed and used not only in the living room but also in the bedroom for a comfortable sleep. Therefore, in order to prevent stress-related insomnia, etc., there is a need for technology to reduce noise generated from humidifiers.

Figure 1 is a perspective view of a conventional floating humidifier.

Referring to the drawings, the floating humidifier 1 may include a water tank 10, a floating body 20, and a water tank cover 30.

The water tank 10 contains a fluid inside, and the fluid may be water, for example. Below, for convenience of explanation, explanation will be made on the assumption that the fluid is water.

The floating body 20 floats in the water tank 10 containing the fluid and performs a humidifying operation. The bottom surface of the floating body 20 is formed to slope downward from the edge to the center, and a blowing fan (not shown) may be provided to introduce external air into the floating body 20 through rotational power.

The water tank cover 30 may be fitted to the upper part of the water tank, and may have a hollow formed in the center so that the upper part of the floating body 20 penetrates and is fixed. Accordingly, the upper part of the floating body 20 protrudes to the outside through the hollow, and performs a humidifying operation by discharging water vapor generated inside the floating body 20 to the outside.

Meanwhile, on one upper side of the water tank 10, a plurality of through holes 11 may be provided through which external air sucked through the blowing fan inside the floating body 20 passes. At this time, the noise generated inside the water tank 10 can be discharged in the reverse direction of the external air inflow direction through the plurality of holes 11, which is generated as the plurality of through holes 11 are located at the upper part of the water tank 10. Noise is discharged to the outside without filtration. Accordingly, there is a problem in that a large noise is generated when the humidifier operates.

It is a side view of a dual structure humidifier according to an embodiment, and Figure 8 is a rear perspective view of a dual structure humidifier according to an embodiment of the present specification. Hereinafter, the dual structure humidifier will be described with reference to FIGS. 2 to 8.

2 to 8, the dual structure humidifier 100 includes a water tank 110, a floating body 120, a water tank case 130, a water tank cover 140, a fluid particle discharge rod 150, and a station 160. ) may include.

The water tank 110 is a space in which a fluid is accommodated, and the floating body 120 floats within the water tank 110 in which the fluid is accommodated.

A buoyancy space for generating buoyancy may be formed inside the floating body 120, and a fluid inlet hole 123 and an ultrasonic module 122 may be formed on the bottom of the floating body 120 in a space protruding from the bottom of the floating body 120. ) can be provided.

The fluid inlet hole 123 may be formed in a circular shape, and water may flow into the floating body 120 through the fluid inlet hole 123. The ultrasonic module 122 is inserted and installed inside the floating body 120, and atomizes water flowing into the lower part of the floating body 120 through the fluid inlet hole 123 into water particles through ultrasonic vibration.

As shown in FIG. 3, a separate power cable 161 may be connected to the ultrasonic module 122, and the power cable may extend to the outside through the floating body 120. The power cable 161 may supply power to the blowing fan 121 together with the ultrasonic module 122.

In one embodiment of the present specification, the floating body 120 may include a blowing fan 121. The blowing fan 121 introduces external air into the water tank 110 and the floating body 120, or discharges the air inside the floating body 120 to the outside.

Specifically, referring again to FIG. 2, the blowing fan 121 introduces external air into the water tank 110 and the floating body 120 through the air intake port 131 of the water tank case 130, which will be described later (A ->B->C1 or A->B->C2), the introduced air passes through the hole formed in the upper part of the floating body 120 together with the fluid particles (water particles) atomized by the ultrasonic module 122 to the outside. It is discharged as (D). The floating body 120 performs a humidifying operation to supply moisture to a specific space through this operation.

In this embodiment, the blowing fan 121 is expressed as being included in the floating body 120 and provided on the side of the floating body 120, but the location of the blowing fan 121 is not necessarily limited to this, and the air intake port 131 It may include all locations that can perform the function of introducing external air into the water tank 110 and the floating body 120, such as the surroundings, the upper part of the water tank 110, and the inner peripheral surface of the water tank case 130.

Referring to Figures 4 to 7, the water tank case 130 is provided to form a predetermined distance from the water tank and surround the outer circumference of the water tank 110. Accordingly, the diameter of the water tank case 130 is formed to be larger than the diameter of the water tank 110, and covers the outer peripheral surface of the water tank 110, forming a dual structure of the water tank 110 and the water tank case 130.

On one side of the water tank case 130, an air intake port 131 communicating with the power cable guide portion 132 and the blowing fan 121 may be formed that protrudes outward to accommodate the power cable 161 on the inner peripheral surface. Accordingly, when the blowing fan 121 rotates, external air flows into the dual structure humidifier 100 through the air intake port 131.

Meanwhile, inside the dual structure humidifier 100, various noises may occur, such as noise due to the vibration of the ultrasonic module 122, noise due to the rotational movement of the blowing fan 121, and noise due to friction of water inside the water tank 110. there is.

In order to reduce such noise, the air intake port 131 may be formed at a height lower than the top of the water tank 110 based on the bottom surface of the water tank.

Since sound travels in a straight line like light, passing through a curved section has the effect of reducing noise. Therefore, it is important to form a structure that prevents the generated noise from being discharged directly to the outside from the top of the water tank 110.

Since the emission path of noise is opposite to the inflow direction of external air shown in FIG. 2 through the air intake port 131 (C1->B->A or C2->B->A), the air intake port 131 When formed at a height lower than the top of the water tank 110, the path through which noise is emitted through the curved section becomes longer. Through this path, noise is reduced through friction between the outer peripheral surface of the water tank 110 and the inner peripheral surface of the water tank case 130.

In addition, the higher the height of the top of the water tank 110, the longer the noise emission path, which improves the noise reduction effect of the dual structure humidifier 100, so the height from the bottom of the top of the water tank 110 can be formed to be sufficiently high.

In one embodiment, the air intake port 131 may have the shape of an open surface at the bottom of the water tank case 130, as shown in FIG. 8, but the shape of the air intake port 131 is not necessarily limited thereto. , can be formed in various shapes such as multiple perforated holes, open surfaces, and lines.

Meanwhile, in Figure 8, the smaller the height or size of the air intake port 131, the better the noise reduction effect. In other words, if the height or size of the air intake port 131 is small, the amount of external air flowing in decreases, so the amount of noise generated also decreases.

However, if the inflow of external air decreases, the discharged water particles also decrease, which may reduce the humidification effect. Therefore, it is desirable to determine the size of the air intake port 131 within a range that maintains an appropriate humidification effect.

The water tank cover 140 is provided on the upper part of the water tank case 130 and may be formed to correspond to the shape of the water tank case 130. The water tank cover 140 can be fitted with the upper part of the water tank case 130 and can be mounted to be easily separated.

In addition, the water tank cover 140 is formed to correspond to the shape of the water tank case 130, thereby sealing the upper part of the dual structure humidifier 130 together with the water tank case 130, preventing fluid loss in the water tank 110, and reducing noise. It can be reduced.

Referring again to FIG. 2, the water tank cover 140 may be provided with a water drain perforation 141. The water tank cover 140 may be formed to slope downward toward the center, and water generated on the outer surface of the water tank cover 140 due to a water droplet phenomenon is guided to the center of the water tank cover 140 along the slope. Thereafter, the water contained in the center of the water tank cover 140 flows into the dual structure humidifier 100 along the water drain perforation 141.

In this embodiment, the water drain perforation 141 is expressed as a curved surface, but it is not necessarily limited thereto and may be formed in various shapes at various positions on the water tank cover 140.

The fluid particle discharge rod 150 is coupled to the upper part of the floating body 120 and guides the fluid particles generated through the humidifying operation of the floating body 120 to be discharged upward to the outside. In one embodiment, the fluid particle discharge rod 150 may be formed integrally with the water tank cover 140 and the water tank case 130. When formed integrally, the sealing force is improved, thereby improving humidification and noise reduction effects. You can.

Additionally, in one embodiment, the water tank 110 may be formed integrally with the water tank case 130. In this case, there is an effect of reducing noise generated by friction in the space between the water tank 110 and the water tank case 130.

Additionally, in another embodiment, the dual structure humidifier 100 may further include a noise reduction member (not shown) in the space between the water tank case 130 and the water tank 110. The noise reduction member may be a material that can absorb shock, such as a sponge, and the noise reduction member can reduce the flow of the water tank case 130 and prevent collisions between the water tank case 130 and the water tank 110. . Therefore, by using a noise reduction member, damage to the water tank case 130 due to collision can be prevented and noise can be reduced.

The station 160 is in surface contact with the bottom of the water tank 110 and may include a power source (not shown), a control unit (not shown), and a lighting device 162 therein.

The power unit receives power from the outside and supplies power to the blower fan 121 and the ultrasonic module 122 through the power cable 161, and the control unit controls the overall humidification operation of the dual structure humidifier.

The lighting device 162 may be a lighting device using, for example, LEDs, and may provide a visual effect to the user through various color light sources and illuminance control.

Figure 9 is a perspective view of a dual structure humidifier according to another embodiment of the present specification.

Referring to the drawing, the lower part of the water tank case 130 is bent in the direction of the water tank 110 to form a closed structure connected to the lower part of the water tank 110, and the air intake port 131 extends in the circumferential direction of the water tank case 130. Accordingly, it can be formed with multiple perforations.

The size of the air intake port 131 may be different from each other. As the size of the air intake port 131 decreases, the noise decreases, but the amount of humidification decreases, so the size of each air intake port 131 determines the level of noise and the amount of humidification. It can be decided taking into account.

In this way, when the air intake port 131 is formed with a plurality of perforated holes along the circumferential direction of the water tank case 130, the dual structure humidifier 100 can be arranged regardless of the direction of the air intake port 131, improving convenience. It can be.

Figure 10 is a table showing noise measurement results using a noise meter in an embodiment of the present specification.

Referring to the drawings, humidifiers have different noise levels depending on the amount of humidification. In the case of the conventional invention shown in Figure 1, the humidification amount is 63.9 dB in stage 1, 62.8 dB in stage 2, and 59.9 dB in stage 3, whereas in the case of the present invention, the humidification amount is 36.2 dB in stage 1, 38.5 dB in stage 2, and 38.5 dB in stage 3. At 42dB, it can be seen that the noise reduction effect is greatly improved compared to the conventional one at all stages.

As above, the dual structure humidifier according to an embodiment of the present specification can reduce noise generated inside the water tank through the dual structure of the water tank and the water tank case.

In addition, the dual structure humidifier according to an embodiment of the present specification can adjust the degree of noise reduction through various types of air intake ports.

In addition, the dual structure humidifier according to an embodiment of the present specification can efficiently reduce noise through a noise reduction member provided between the water tank and the water tank case.

As described above, the present invention has been described with reference to the illustrative drawings, but the present invention is not limited to the embodiments and drawings disclosed herein, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that transformation can occur.
