Description

Air humidifying device

Technical Field

The utility model relates to an air humidifying device.

Background

With the development of economy and the improvement of the living standard of people, the requirements of people on the quality of life and health are higher and higher, and meanwhile, the requirements on the humidity of the air environment in industrial applications such as textile papermaking, cold fresh storage, laboratories and the like are more and more strict. Therefore, air humidifiers that humidify air and control the humidity of air have been widely used.

As shown in fig. 1, fig. 1 is a schematic diagram of a conventional air humidifier with a water reservoir and a rotary spray structure, which includes a water reservoir 110 and a rotary spray structure 120. The rotary spraying structure 120 includes a funnel-shaped rotating portion 121, a motor for driving the rotating portion 121 to rotate, and a water breaking wall 122. When the rotary spraying structure is operated, the rotating part 121 is rotated at a high speed by the driving of the motor, and the water in the water storage part 110 is sucked to the upper part of the rotating part 121 and is separated from the upper end of the rotating part 121 to be sprayed out in a centrifugal direction under the action of the centrifugal force generated thereby. The water droplets flying at high speed are further broken by hitting the water breaking wall 122. Thereby, the water droplets are broken into finer mist, and are mixed with the air flow passing through the rotary centrifugal type atomizing structure 120 and then blown out from the air outlet.

As shown in fig. 1, the air may be humidified by a rotary spray structure, but when the air is sufficiently dry or a higher amount of humidification is required for a certain period of time, the amount of humidification mixed into the air is increased by increasing the speed of the motor or shortening the distance between the water-breaking wall and the rotary part to increase the speed at which the water droplets collide with the water-breaking wall.

However, increasing the rotational speed of the motor consumes more energy such as electric power. Further, when higher humidification efficiency is required, the motor may not meet the requirement even if the rotation speed of the motor reaches the maximum, and the motor with the higher rotation speed needs to be replaced, which increases the cost.

Further, shortening the distance between the water-breaking wall and the rotating portion causes an excessively narrow air passage through which air passes, increasing pressure loss, and decreasing the air volume, which may in turn decrease the amount of humidification that can be mixed within a certain period of time.

In summary, there is a need for an air humidifier that does not increase the rotational speed of the motor or replace the motor, does not shorten the distance between the water-breaking wall and the rotating portion, and can also improve the humidification efficiency.

To assist in further comminution of the liquid.

The above is the structure of the air humidifier 200.

As shown in fig. 9, the following description will be made of a process of humidifying air flowing through the air humidifying device 200.

When the air humidifying device 200 is operated, the water absorbing part 250 rotates at a high speed under the driving of the motor 610, and because the lower end of the water absorbing part 250 is soaked in the liquid stored in the water storage part 240, the liquid in the water storage part 240 enters the inner peripheral side of the water absorbing part 250 through the water absorbing opening 310 under the action of centrifugal force generated by the high-speed rotation of the water absorbing part 250 and ascends along the inner peripheral wall surface of the cylinder wall 330 of the water absorbing part 250.

In this embodiment, since the notch 510 extending toward the water discharge port 320 is provided on the outer periphery of the water inlet 310 of the water absorbing section 250, when the water absorbing section 250 rotates at a high speed, the liquid on the outer periphery side of the water absorbing section 250 can more easily enter the inner periphery side of the water absorbing section 250, and the liquid can be prevented from entering the inner periphery side of the water absorbing section 250 due to the vacuum formed on the inner periphery side of the water absorbing section 250,

since the water absorbing part 250 is provided with the plurality of water absorbing ribs 350, when the water absorbing part 250 rotates at a high speed, the water absorbing ribs 350 rotate at a high speed around the shaft 840. When the water absorption ribs 350 are soaked in the liquid, the liquid is stirred at a high speed in the liquid, so that the liquid can climb upwards more easily. Further, since the water absorption rib 350 is inclined to the opposite side to the rotation direction, the liquid more easily ascends along the water absorption rib 350 when entering the inner circumferential side of the cylindrical wall 330 of the water absorption part 250. This can increase the water absorption amount of the water absorption unit 250, thereby increasing the humidification amount.

The notch 510 is provided on the opposite side of the rotation direction of the water absorbing rib 350, and the distance from the lower edge 420 of the water absorbing rib 350 located on the opposite side of the rotation direction of the notch 510 is smaller than the distance from the upper edge 410, so that when liquid enters the inner peripheral side of the cylinder wall 330 from the notch 510, the liquid will climb up to the upper edge 410 along the lower edge 420 of the water absorbing rib 350 by being pushed by the water absorbing rib 350.

Since the fine water spray holes 340 are provided between the top water breaker plate 710 and the sub-water breaker plate 720, and the sub-water breaker plates 720, when part of the liquid rises up to the fine water spray holes 340, the friction force with the cylinder wall 330 is lost, and the liquid passes through the fine water spray holes 340 by the centrifugal force, is sprayed toward the outer peripheral side of the water suction portion 250, and flows toward the outer periphery of the sub-water breaker plates 720 along the upper surface of the sub-water breaker plates 720.

However, under air resistance, the liquid will have a reduced velocity as it flies off tangentially.

Since the atomizing part 270 is provided with the guide rib 730, the guide rib 730 rotates at the same speed as the water absorbing part 250. At this time, the liquid will impact on the diversion surface 830 on the diversion rib 730 on one side of the rotation direction, at this time, friction force will be generated between the liquid and the diversion surface 830, the diversion rib 730 generates thrust force to the liquid in the rotation direction, and the friction force and the thrust force will generate resultant force to the outer periphery side of the auxiliary water crushing disc 720. When the liquid maintains or increases the speed under the action of the resultant force, the liquid flows to the outer circumferential side along the auxiliary water crushing disc 720 and the flow guide ribs 730 until the liquid is separated from the outer circumferential edge of the auxiliary water crushing disc 720, and then the liquid is sprayed to the outer circumferential side from the auxiliary water crushing disc 720. That is, the speed of the liquid flying out is increased by the auxiliary water crushing disk 720 and the guide ribs 730, thereby increasing the efficiency of crushing the liquid.

Since the guide ribs 730 are inclined to the opposite side of the rotation direction, the liquid smoothly moves to the outer circumferential end 820 of the guide ribs 730 along the direction of the guide ribs 730. The closer the liquid is to the outer circumferential end 820 of the guide rib 730 when it is separated from the guide rib 730, the greater the thrust force is applied, and the greater the acceleration when it is separated from the guide rib 730.

Similarly, when a portion of the liquid rises to the spout 320 without passing through the fine water jet holes 340, it spreads to the outer circumferential side along the top water breaker plate 710.

The liquid discharged from the water discharge ports 320 and the fine water discharge holes 340 is discharged to the outer circumferential side along the top water breaker plate 710 and the sub breaker plate, and then collides against the water breaker wall 280 on the outer circumferential side of the water absorbing part 250.

The greater the velocity at which the liquid is discharged to the outer peripheral side of the water absorbing portion 250, the greater the velocity at which the liquid impinges on the water disintegrating wall 280 on the outer peripheral side of the water absorbing portion 250, and the finer the disintegration can be.

When air enters from the air inlet 210 of the air humidifier 200 and flows through the air passage 230 formed between the atomizing unit 270 and the water breakup wall 280, the liquid broken up by the water breakup wall 280 is mixed and blown out from the air outlet 220.

Since the flow guide surface 830 of the flow guide rib 730 is a curved surface that is convexly curved to the opposite side of the rotation direction, the liquid can be more smoothly diffused to the outer circumferential side along the flow guide surface 830, and the liquid is prevented from being pressed back to the inner circumferential side when hitting the flow guide surface 830, thereby increasing the humidification amount.

In addition, when the water guard 620 is provided above the upper water-breaking pan, there is a possibility that the speed of water spraying may be insufficient.

Since the water guard 620 is disposed above the top water breaker 710, when the distance between the water guard 620 and the top water breaker 710 is small, the liquid diffused from the water jet 320 to the top water breaker 710 moves to the outer circumferential side in the gap formed between the top water breaker 710 and the water guard 620 under the action of tension, and can be ejected to the outer circumferential side at high speed even without the flow guide rib 730. However, when the distance between the water guard 620 and the top water breaker plate 710 is large, a space formed by them cannot apply pressure to the liquid, and the speed of the liquid spreading to the outer circumferential side along the top water breaker plate 710 is insufficient, resulting in difficulty in further breaking the liquid.

Therefore, as shown in fig. 10, the top water breaker plate 710 may be provided with the guide ribs 730, so that the liquid can be ejected to the outer circumferential side at a sufficient speed even if the distance between the water guard plate 620 and the top water breaker plate 710 is large.

Thereby increasing the amount of humidification of the air humidification device 200.
