Description

Technical Field

[0001] This invention relates to air conditioning equipment technology, and more specifically, to a humidification component and an air conditioner. Background Technology

[0002] When an air conditioner is heating, the relative humidity of the indoor air decreases, resulting in a poor user experience. Therefore, humidifying the indoor air becomes necessary when the air conditioner is heating. Existing humidification solutions for air conditioners include ultrasonic humidification, wet film humidification, steam humidification, waterless humidification, and centrifugal humidification.

[0003] Ultrasonic humidification solution: Ultrasonic vibrating plates are easily affected by scale and other factors, resulting in short lifespan and easy damage. This solution is only partially used in portable humidifiers and not in air conditioners.

[0004] Wet membrane humidification solution: Wet membranes have problems such as short lifespan, easy growth of bacteria, need to be replaced regularly, and high purchase cost. This solution is only partially used in machines such as cabinet air conditioners that can be easily replaced, and is not used in machines such as duct air conditioners that require climbing to operate.

[0005] Steam humidification solutions have several drawbacks: high power consumption, loud boiling noise, secondary heating of air by high-temperature steam leading to poor user comfort, rapid condensation of high-temperature steam during humidification through pipes resulting in poor air delivery distance and effectiveness, high manufacturing costs, and high operating costs. This solution is only partially used in central humidifiers and not in air conditioners.

[0006] Waterless humidification solutions include structures such as rotary moisture absorption (using MOF (porous crystalline material) membrane to extract moisture from the outside), heating dehumidification, and fan-driven moisture delivery. These solutions suffer from problems such as system complexity, high cost, and low humidification capacity. Furthermore, when the outdoor humidity is low, the MOF membrane cannot effectively extract moisture from the outside.

[0007] Centrifugal humidification solution: In order to obtain a high water output speed, the water needs to be continuously rotated and accelerated. Therefore, the radius of the rotating disc for accelerating the water needs to be relatively large (generally not less than 80mm, which cannot be used in air conditioners due to its large space occupation). Summary of the Invention

[0008] This invention provides a humidification component that has the advantages of simple structure, low manufacturing cost, low energy consumption, and good humidification effect.

[0009] This invention also provides an air conditioner.

[0017] In some exemplary embodiments, the jet nozzles include a plurality of nozzles, which are arranged sequentially along the axial direction of the waterwheel.

[0018] In some exemplary embodiments, the jet nozzles include a plurality of nozzles, which are sequentially arranged circumferentially and axially on the water impeller.

[0019] In some exemplary embodiments, the water-spraying wheel includes: a base ring; and a plurality of curved and sheet-like blades located outside the base ring and arranged sequentially along the circumference of the base ring, each blade being connected to the base ring via an end adjacent to the base ring, and the water-spraying area of ​​each blade being located on its protruding side.

[0020] In some exemplary embodiments, the water-spraying wheel includes: a plurality of curved and sheet-like water-spraying plates; and a plurality of connecting plates, wherein the plurality of water-spraying plates and the plurality of connecting plates are arranged in a circumferentially alternating and correspondingly grouped together, wherein the radially outer ends of the water-spraying plates in the same group are connected to the radially outer ends of the connecting plates to form the wheel blades, and the radially inner ends of adjacent water-spraying plates in adjacent groups are connected to the radially inner ends of the connecting plates, wherein the water-spraying area of ​​each wheel blade is located on the protruding side of the water-spraying plate.

[0021] In some exemplary embodiments, the water jet further includes: a base plate, a plurality of water jet plates and a plurality of connecting plates located on one side of the base plate and connected to the base plate, and the base plate having a recessed groove facing the inner side of the area enclosed by the plurality of water jet plates and the plurality of connecting plates, the bottom of the groove having a shaft hole and a drainage hole.

[0026] The humidification component provided in this invention uses a driving device to drive a water-spraying wheel to rotate, spraying water from the spray nozzle into the atomizing chamber.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0042] The humidification components provided in the embodiments of the present invention, such as Figures 1 to 8 As shown, it includes: an atomizing chamber 100, which has a spray nozzle 110 and a mist outlet 120; a water-spraying wheel 200, which is disposed inside the atomizing chamber 100, with the spray nozzle 110 facing the blade 210 of the water-spraying wheel 200, and the area of ​​the blade 210 used for spraying water is curved; and a driving device, which is connected to the water-spraying wheel 200 and is configured to drive the water-spraying wheel 200 to rotate.

[0043] This humidification component uses a drive unit to rotate a water-spraying wheel 200, spraying water from a nozzle 110 into an atomizing chamber 100. The water sprayed from the nozzle 110 (forming a water column 500) continuously impacts the blades 210 of the rotating water-spraying wheel 200. The impact of the blades 210 with the water breaks up and atomizes the water to form water mist. The water mist flows out of the mist outlet 120 from the atomizing chamber 100 and is supplied to a designated space (such as an indoor space) to humidify the air in the designated space. This solution is not only simple in structure, low in manufacturing cost, low in energy consumption, and has a good humidification effect, but it is also easy to apply to air conditioners. Moreover, the area of ​​the blades 210 used for spraying water is curved, and the curved surface has a better atomization effect on the water impacting it, so more water mist is generated in the atomizing chamber 100, thus the humidification effect of the humidification component is better.

[0044] Better, such as Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the area of ​​the impeller 210 used for spraying water is a convex surface. The convex surface is preferably set as an involute surface 211. By reasonably setting the involute surface 211 and the spray nozzle 110, the water breaking angle (i.e., the water breaking angle) can always be close to or at the optimal breaking angle of 90 degrees. In this way, the impeller 210 will generate more water mist by breaking and atomizing the water impacted on it.

[0045] In some examples, such as Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the axis of the nozzle 110 and the axis of the water impeller 200 are perpendicular straight lines of different planes, with a distance of R. The involute surface 211 is constructed with R as the base circle from one end near the axis of the water impeller 200 to the end away from the axis of the water impeller 200 (that is, the part of the impeller 210 that contacts the water column is an involute surface 211 constructed with R as the base circle). In this way, the angle between the water column impacting the involute surface 211 and the involute surface 211 (this angle is the water breaking angle) is always a right angle, that is, the water column and the involute surface 211 always collide perpendicularly (that is, the water breaking angle of the impeller 200 blade 210 to the water is always 90 degrees). Therefore, the involute surface 211 has a better water breaking and atomization effect. Figure 9 and Figure 10 As shown, for the technical solution where the impeller 210 is a straight plate impeller 210', the angle at which the straight plate impeller 210' breaks up the water varies. Taking a technical solution with R≥15mm and n≥7 as an example, the angle at which the straight plate impeller 210' breaks up the water gradually changes from 38 degrees to 90 degrees. At most, the angle between each straight plate impeller 210' and the water column is 90 degrees. It can be seen that the water breaking and atomization effect of the straight plate impeller 210' is significantly worse than that of this application.

[0046] In some embodiments, the number of blades 210 n ≥ 360 ° / θ, θ=arcos(R / R) max ), R max Let θ be the maximum rotation radius of the water impeller 200, and θ be the central angle of the area traversed by the water column on a single impeller blade. This scheme ensures that during the rotation of the water impeller 200, the water ejected from the nozzle 110 always impacts the involute surface 211, meaning the involute surface 211 is constantly breaking up the water ejected from the atomizing nozzle 110. Therefore, more water mist is generated within the atomizing chamber 100, resulting in better humidification of the humidification component. Preferably, n≥4, R≥15mm. In this application, if... Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, n is set to 7.

[0047] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the nozzle 110 is located on the peripheral wall of the atomizing chamber 100 and its axis is arranged horizontally. The axis of the water impeller 200 is set vertically. At this time, the axis of the nozzle 110 and the axis of the water impeller 200 are perpendicular straight lines with different planes, and the nozzle 110 faces the water impeller 200. The mist outlet 120 is located on the top wall of the atomizing chamber 100 and is set upward. In the rotation direction of the water impeller 200, the involute curved surface 211 is located on the front side of the impeller blade 210. In this scheme, the water column and the involute curved surface 211 always collide perpendicularly to each other (that is, the breaking angle of the impeller blade 210 on the water is always 90 degrees), which realizes the optimal breaking and atomization of water by the involute curved surface 211.

[0048] The water velocity of the jet nozzle 110 can be set relatively low, the rotational speed of the impeller 200 (e.g., 2000 rpm to 3000 rpm) can be set relatively high, and the diameter of the impeller 200 can be set relatively small. However, at the impact point, the relative velocity between the water and the impeller 200 can be exceptionally high. For example, if the water velocity is only 20 mm / s, the rotational speed of the impeller 200 is set to 2000 rpm to 3000 rpm, and the maximum radius of the impeller 200 can be set to no less than R+4 mm, the relative velocity between the water and the impeller 200 can easily reach 4400 mm / s. This is equivalent to a 220-fold increase in water velocity (i.e., the water undergoes an acceleration process). Figure 11 As shown in the image, the water atomization effect is particularly good. Therefore, this humidification component can be designed to be relatively small and can be applied to air conditioners.

[0049] It can be, such as Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the injection port 110 includes one; or it can be, as shown in the figure. Figure 6As shown, the spray nozzle 110 includes multiple nozzles, which are sequentially arranged circumferentially around the water impeller 200 and all facing the impeller blades 210. That is, the multiple spray nozzles 110 are sequentially arranged circumferentially on the peripheral wall of the atomizing chamber 100 and all facing the impeller blades 210. Alternatively, the spray nozzle 110 may include multiple nozzles, which are sequentially arranged axially around the water impeller 200 and all facing the impeller blades 210. That is, the multiple spray nozzles 110 are sequentially arranged vertically on the peripheral wall of the atomizing chamber 100 and all facing the impeller blades 210. The impeller 200 has blades 210; or it can be that the spray nozzles 110 include multiple nozzles, which are arranged sequentially in the circumferential and axial directions of the impeller 200. That is, some spray nozzles 110 are arranged circumferentially on the peripheral wall of the atomizing cavity 100, and some spray nozzles 110 are also arranged axially (such as multiple spray nozzles 110 being arranged in multiple rows and columns on the peripheral wall of the atomizing cavity 100). All of these spray nozzles 110 face the impeller blades 210 of the impeller 200. All of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this invention. They will not be elaborated here, and should all fall within the protection scope of this application.

[0050] In one embodiment, such as Figure 6 As shown, in the circumference of the atomizing chamber 100, the spray nozzle 110 and the impeller 210 correspond one-to-one. This makes the impeller more efficient at atomizing water. Compared with only one spray nozzle 110, this scheme increases the amount of water mist generated by n times, which means that the humidification capacity of the humidification component is increased by n times.

[0051] In some embodiments, such as Figure 8 As shown, the water-pumping wheel 200 includes: a base ring 220 with a shaft hole formed inside, through which a drive device is connected for transmission, thereby driving the water-pumping wheel 200 to rotate; and multiple curved, sheet-like blades 210, which are located outside the base ring 220 and arranged sequentially along the circumference of the base ring 220. Each blade 210 is connected to the base ring 220 through one end adjacent to the base ring 220, and an involute curved surface 211 is located on the convex side of the blade 210. This water-pumping wheel 200 has a simple structure and is easily integrally injection molded. The number of blades 210 can be 4, 5, 6, 7, or 8, etc., all of which can achieve the purpose of this application. Their intent does not depart from the design concept of this invention and will not be elaborated further here; all such examples should fall within the protection scope of this application.

[0052] In other embodiments, Figure 3 , Figure 4 and Figure 6As shown, the water jet 200 includes: multiple curved and sheet-like water jet plates 231; and multiple connecting plates 232. The multiple water jet plates 231 and multiple connecting plates 232 are arranged in a circumferential alternation and correspond one-to-one in a group. The radial outer ends of the water jet plates 231 in the same group are connected to the radial outer ends of the connecting plates 232 to form a wheel blade 210. The radial inner ends of the adjacent water jet plates 231 of the adjacent wheel blades 210 are connected to the radial inner ends of the connecting plates 232. The involute curved surface 211 is located on the convex side of the water jet plate 231. With this design, the wheel blade 210 has higher strength and is less prone to breakage and damage.

[0053] Furthermore, if Figure 2 As shown, the water-spraying wheel 200 also includes: a base plate 233, multiple water-spraying plates 231 and multiple connecting plates 232 located on one side of the base plate 233 and connected to the base plate 233, and the base plate 233 is provided with a recessed groove 234 facing the inner side of the area enclosed by the multiple water-spraying plates 231 and multiple connecting plates 232, and the bottom of the groove 234 is provided with a shaft hole and a drain hole. The driving device is connected to the shaft hole for transmission, thereby driving the water-spraying wheel 200 to rotate. The base plate 233 is located on the upper side of the multiple water-spraying plates 231 and multiple connecting plates 232, so that the water falling on the base plate 233 will flow into the groove 234 under the action of gravity, and then flow down from the drain hole through the inner side of the area enclosed by the multiple water-spraying plates 231 and multiple connecting plates 232.

[0054] Furthermore, such as Figure 2 As shown, the humidification assembly also includes a first baffle 400, located between the water jet 200 and the bottom wall of the atomizing chamber 100. The first baffle 400 is configured to block the downward-blowing airflow generated by the operation of the water jet 200, preventing the water jet 200 from rotating and stirring the water below the first baffle 400 in the atomizing chamber 100, thus preventing the water below the first baffle 400 from oscillating and generating noise. The water level in the atomizing chamber 100 is below the first baffle 400. Furthermore, water falling onto the substrate 233 will flow into the settling tank 234 under gravity, and then fall from the drain hole through the inner side of the area enclosed by multiple water jet plates 231 and multiple connecting plates 232 onto the first baffle 400.

[0055] Furthermore, such as Figure 2 As shown, the side of the first baffle 400 facing the water wheel 200 is inclined (as the first baffle 400 is tilted), so that the water falling on the first baffle 400 can more easily flow to the bottom of the atomizing chamber 100 under the action of gravity.

[0056] In some examples, such as Figure 1 and Figure 2As shown, the driving device includes a fan 300, which is located outside the atomizing chamber 100 and is connected to the water impeller 200. The air inlet and outlet of the fan 300 are both connected to the outside of the atomizing chamber 100. The mist outlet 120 is located on the top wall of the atomizing chamber 100 and faces upwards. The axis of the mist outlet 120 is vertically aligned. The air outlet of the fan 300 is on one side of the axis of the mist outlet 120 and faces it. The air blown from the air outlet of the fan 300 passes above the mist outlet 120, creating a negative pressure at the mist outlet 120. Under this negative pressure, the water mist inside the atomizing chamber 100 is blown from the mist outlet 120 into a space following the airflow direction from the air outlet of the fan 300. The water impeller 200 is driven by the fan 300, thus eliminating the need for a separate motor.

[0057] In one embodiment, such as Figure 1 and Figure 2 As shown, the fan 300 includes a motor 310, an impeller 320, and a volute 330. The volute 330 is located outside the atomizing chamber 100 and installed on top of the atomizing chamber 100. The impeller 320 is located inside the volute 330. The motor 310 is located above the volute 330 and is drivenly connected to the impeller 320. The shaft of the impeller 320 extends into the atomizing chamber 100 and is drivenly connected to the shaft hole of the water jet 200. The air inlet 332 of the volute 330 is located on the top of the volute 330 and faces upwards. The air outlet 331 of the volute 330 is located on the peripheral wall of the volute 330 and serves as the air outlet of the fan 300. The motor 310 is equipped with a motor cover 311.

[0058] In some examples, such as Figure 1 As shown, the bottom of the atomizing chamber 100 is provided with a drain outlet 130. The humidification assembly also includes a water pump, which is located outside the atomizing chamber 100. The inlet of the water pump is connected to the drain outlet 130, and the outlet of the water pump is connected to the end of the spray nozzle 110 facing the outside of the atomizing chamber 100. The end of the spray nozzle 110 facing the inside of the atomizing chamber 100 faces the impeller 210 of the water agitator 200. Of course, the atomizing chamber 100 can also be provided with a water inlet, etc., which can also achieve the purpose of this application. The purpose does not depart from the design concept of this invention, and will not be elaborated here. All of these should fall within the protection scope of this application.

[0059] The air conditioner provided in this embodiment of the invention (not shown in the figure) includes a main body with an indoor heat exchange duct and a humidification component as described in any of the above embodiments. The humidification component is disposed on the main body, and the mist outlet is connected to the indoor heat exchange duct.

[0060] This air conditioner possesses all the advantages of the humidification component proposed in any of the above embodiments, which will not be repeated here.

[0061] Among them, the air conditioner includes split air conditioners, integrated air conditioners, air duct machines, central air conditioners, etc.

[0062] In summary, for the humidifying component provided by the embodiment of the present invention, the driving device drives the water wheel to rotate, sprays water from the self-spraying port into the atomizing cavity, and the water sprayed from the spraying port continuously impacts on the blades of the rotating water wheel. The blades break and atomize the water impacting on them to form water mist, and the water mist flows out of the atomizing cavity from the mist outlet and is supplied to the room to humidify the indoor air. This solution not only has a simple structure, low manufacturing cost, low energy consumption, and good humidifying effect, but is also very easy to be applied to air conditioners. Moreover, the area of the blade for hitting water is a curved surface, and the curved surface has a better effect of breaking and atomizing the water impacting on it, generating more water mist, so that the humidifying effect of the humidifying component is better.
