Description

Technical Field

[0001] The utility model relates to air conditioning equipment technology, and more specifically, to a humidifying component and an air conditioner. Background Art

[0002] When the air conditioner is heating, the relative humidity of the indoor air decreases, resulting in a reduced user experience. Therefore, it becomes necessary to humidify the indoor air 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 vibration plates are easily affected by scale and have problems such as short life and easy damage. This solution is only partially used in portable humidifiers and not in air conditioners.

[0004] Wet film humidification solution: The wet film has problems such as short life, easy breeding of bacteria, need for regular replacement, and high purchase cost. This solution is only partially used in machines that can be easily replaced, such as cabinet machines, and is not used in machines that require high-altitude operation, such as duct machines.

[0005] Steam humidification solution: There are problems such as high power consumption, loud noise when boiling water, secondary heating of air by high-temperature steam resulting in poor user comfort, rapid condensation of high-temperature steam when wet air is delivered through pipes, short delivery distance of wet air and poor effect, high manufacturing cost and high use cost. This solution is only partially used in central humidifiers and is not used in air conditioners.

[0006] Waterless humidification solution: including rotary wheel moisture absorption (using MOF (porous crystalline material) membrane to take moisture from the outside), heating dehumidification, fan moisture supply and other structures. There are problems such as complex system, high cost, small humidification capacity, etc. Moreover, when the outdoor humidity is low, the MOF membrane cannot effectively take moisture from the outside.

[0007] Centrifugal humidification solution: In order to obtain a higher water outlet speed, the water needs to be continuously accelerated in rotation. Therefore, the radius of the turntable that accelerates the water is required to be relatively large (generally not less than 80mm, which is not suitable for air conditioners because it occupies a large space).

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0042] The humidification component provided in the embodiment of the utility model is as follows Figures 1 to 8 As shown, it includes: an atomizing chamber 100, the atomizing chamber 100 is provided with an injection port 110 and a mist outlet 120; a water-pumping wheel 200, the water-pumping wheel 200 is arranged in the atomizing chamber 100, the injection port 110 faces the wheel blades 210 of the water-pumping wheel 200, and the area of ​​the wheel blades 210 used for pumping water is a curved surface; and a driving device, the driving device is transmission-connected to the water-pumping wheel 200, and the driving device is configured to drive the water-pumping wheel 200 to rotate.

[0043] In the humidifying component, a driving device drives the water-beating wheel 200 to rotate, and water is sprayed from the injection port 110 into the atomizing chamber 100. The water sprayed from the injection port 110 (the formed water column 500) continuously impacts the wheel blades 210 of the rotating water-beating wheel 200. The wheel blades 210 collide with the water to break the water into atomized form and form water mist. The water mist flows out of the atomizing chamber 100 from the mist outlet 120 and is supplied to a set space (such as indoors), so as to humidify the air in the set space. This solution is not only simple in structure, low in manufacturing cost, low in energy consumption, and good in humidification effect, but also very easy to be applied to air conditioners. Moreover, the area of ​​the wheel blade 210 used for pumping water is a curved surface, and the curved surface has a better effect of breaking and atomizing the water impacting thereon, so that more water mist will be generated in the atomizing chamber 100, and thus the humidification effect of the humidifying component is better.

[0044] Better, if Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the area of ​​the impeller 210 used for hitting water is a convex surface, and the convex surface is preferably set to an involute surface 211. By reasonably setting the involute surface 211 and the injection port 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, so that the impeller 210 has a breaking and atomizing effect on the water impacting it, and can generate more water mist.

[0045] In some examples, such as Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the axis of the jet port 110 and the axis of the water wheel 200 are skew vertical straight lines, and the distance between them is R. The involute surface 211 is constructed from one end close to the axis of the water wheel 200 to the end away from the axis of the water wheel 200 with R as the base circle (that is, the part of the blade 210 that contacts the water column is the 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 (the angle is the water crushing angle) is always right angles, that is, the water column and the involute surface 211 are always vertically colliding (that is, the water crushing angle of the blade 210 of the water wheel 200 is always 90 degrees), so the involute surface 211 has a better effect of crushing and atomizing water. Fig. 9 and Fig.10 As shown, for the technical solution in which the blade 210 is a straight blade 210', the breaking angle of the straight blade 210' on water is variable. Taking a technical solution with R ≥ 15 mm and n ≥ 7 as an example, the breaking angle of the straight blade 210' on water gradually changes from 38 degrees to 90 degrees, and the angle between each straight blade 210' and the water column is 90 degrees at most for a moment. It can be seen that the breaking and atomizing effect of the straight blade 210' on water is significantly worse than that of the present application.

[0046] In some embodiments, the number n of blades 210 is ≥ 360. ° / θ,θ=arcos(R / R max ), R max is the maximum rotation radius of the water wheel 200, and θ is the central angle of the area where the water column passes on a single blade. This solution can ensure that during the rotation of the water wheel 200, the water ejected from the jet port 110 always hits the involute surface 211, that is, the involute surface 211 is always breaking up the water ejected from the atomizing jet port 110, so more water mist will be generated in the atomizing cavity 100, so the humidification effect of the humidification component is better. 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, Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the injection port 110 is located on the peripheral wall of the atomizing chamber 100, and the axis is arranged horizontally, and the axis of the water-beating wheel 200 is set vertically. At this time, the axis of the injection port 110 and the axis of the water-beating wheel 200 are skewed vertical straight lines, and the injection port 110 faces the water-beating wheel 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-beating wheel 200, the involute surface 211 is located on the front side of the blade 210. In this scheme, the water column and the involute surface 211 are always in vertical collision with each other (that is, the blade 210 of the water-beating wheel 200 always has a 90 degree crushing angle to the water), thereby realizing the optimal crushing and atomization of the water by the involute surface 211.

[0048] In the present application, the water outlet speed of the jet port 110 can be set relatively low, the rotation speed of the water wheel 200 (such as 2000rpm to 3000rpm) can be set relatively high, and the diameter of the water wheel 200 can be set relatively small, while at the impact point, the relative speed of the water and the water wheel 200 can be particularly large. For example, if the water speed is only 20mm / s, the rotation speed of the water wheel 200 is set to 2000rpm to 3000rpm, and the maximum radius of the water wheel 200 can be set to be no less than R+4mm, the relative speed of the water and the water wheel 200 can easily reach 4400mm / s, which is equivalent to the speed of the water being increased by 220 times (that is, the water speed is increased, such as Fig.11 As shown in FIG. 1 , the water atomization effect is particularly good. Therefore, the humidification component can be designed to be relatively small and can be applied to air conditioners.

[0049] It can be, for example Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the injection port 110 includes one; or it can be, as Figure 6As shown, the injection port 110 includes a plurality of injection ports 110, which are sequentially arranged in the circumferential direction of the water wheel 200 and all face the blades 210 of the water wheel 200, that is, the plurality of injection ports 110 are sequentially arranged on the peripheral wall of the atomizing chamber 100 along the circumferential direction and all face the blades 210 of the water wheel 200; or it may be that the injection port 110 includes a plurality of injection ports 110, which are sequentially arranged in the axial direction of the water wheel 200 and all face the blades 210 of the water wheel 200, that is, the plurality of injection ports 110 are sequentially arranged on the peripheral wall of the atomizing chamber 100 along the up-down direction and all face the blades 210 of the water wheel 200. The blades 210 of the water wheel 200; or it may be that the jet port 110 includes a plurality of jet ports 110, and the plurality of jet ports 110 are sequentially arranged in the circumferential direction and the axial direction of the water wheel 200, that is, some jet ports 110 are arranged in the circumferential direction on the peripheral wall of the atomizing chamber 100, and some jet ports 110 are also arranged in the axial direction (such as the plurality of jet ports 110 are arranged in multiple rows and columns on the peripheral wall of the atomizing chamber 100), and these jet ports 110 are all facing the blades 210 of the water wheel 200; the above can all achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present utility model, and will not be repeated here, and should all fall within the protection scope of the present application.

[0050] In one embodiment, if Figure 6 As shown, in the circumferential direction of the atomizing chamber 100, the injection port 110 and the impeller 210 correspond one to one, so that the impeller has a better atomization efficiency for water. Compared with only setting one injection port 110, the amount of water mist generated in this solution is increased by n times, that is, the humidification amount of the humidification component is increased by n times.

[0051] In some embodiments, Figure 8 As shown, the water wheel 200 includes: a base ring 220, an axial hole is formed inside the base ring 220, and the driving device is connected to the axial hole in a transmission manner to drive the water wheel 200 to rotate; and a plurality of curved and sheet-shaped blades 210, the plurality of blades 210 are located outside the base ring 220 and are arranged in sequence 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 the involute surface 211 is located on the convex side of the blade 210. The water wheel 200 has a simple structure and is easy to be integrally injection molded. It can be that the plurality of blades 210 are set to 4, 5, 6, 7 or 8, etc., which can achieve the purpose of this application, and its purpose does not deviate from the design concept of the utility model, and will not be repeated here, and should all belong to the protection scope of this application.

[0052] In other embodiments, Figure 3 , Figure 4 and Figure 6As shown, the water wheel 200 includes: a plurality of water-spraying plates 231 that are curved and sheet-shaped; and a plurality of connecting plates 232. The plurality of water-spraying plates 231 and the plurality of connecting plates 232 are arranged in groups alternately in the circumferential direction and one by one. The radial outer ends of the water-spraying plates 231 in the same group are connected to the radial outer ends of the connecting plates 232 to form the blades 210. The radial inner ends of adjacent water-spraying plates 231 of adjacent 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-spraying plates 231. In this scheme, the blades 210 have higher strength and are less likely to break and be damaged.

[0053] Furthermore, if Figure 2 As shown, the water wheel 200 further includes: a base plate 233, a plurality of water-spraying plates 231 and a plurality of 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 sink 234 which is recessed toward the inner side of the area enclosed by the plurality of water-spraying plates 231 and the plurality of connecting plates 232, and the bottom of the sink 234 is provided with an axial hole and a drainage hole.

The base plate 233 is located on the upper side of the plurality of water-spraying plates 231 and the plurality of connecting plates 232, so that the water falling on the base plate 233 will flow into the sink 234 under the action of gravity, and then flow down from the drainage hole through the inner side of the area enclosed by the plurality of water-spraying plates 231 and the plurality of connecting plates 232.

[0054] Furthermore, if Figure 2 As shown, the humidification assembly also includes: a first baffle plate 400, the first baffle plate 400 is located between the water wheel 200 and the bottom wall of the atomizing chamber 100, and the first baffle plate 400 is configured to block the downwardly blowing wind beam formed by the operation of the water wheel 200, to prevent the water wheel 200 from rotating and stirring the water in the atomizing chamber 100 below the first baffle plate 400, causing the water in the atomizing chamber 100 below the first baffle plate 400 to vibrate and generate noise. The water surface in the atomizing chamber 100 is below the first baffle plate 400. Furthermore, the water falling on the base plate 233 will flow into the sink 234 under the action of gravity, and then fall onto the first baffle plate 400 from the drainage hole through the inner side of the area surrounded by multiple water plates 231 and multiple connecting plates 232.

[0055] Furthermore, if Figure 2 As shown, the side of the first baffle plate 400 facing the water wheel 200 is an inclined surface (eg, the first baffle plate 400 is tilted), so that water falling onto the first baffle plate 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 wheel 200 by transmission. The air inlet and the air 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 is arranged upward. The axis of the mist outlet 120 is arranged vertically. The air outlet of the fan 300 is on one side of the axis of the mist outlet 120 and faces the axis of the mist outlet 120. The wind blown out of the air outlet of the fan 300 passes above the mist outlet 120, so that negative pressure is formed at the mist outlet 120. Under the action of negative pressure, the water mist in the atomizing chamber 100 is blown from the mist outlet 120 to the wind direction setting space blown by the air outlet of the fan 300. The water wheel 200 is driven by the fan 300, so that a motor can be saved.

[0057] In one embodiment, if Figure 1 and Figure 2 As shown, the fan 300 includes a motor 310, a wind wheel 320 and a volute 330. The volute 330 is located outside the atomizing chamber 100 and is installed on the top of the atomizing chamber 100. The wind wheel 320 is located inside the volute 330. The motor 310 is located above the volute 330 and is transmission-connected with the wind wheel 320. The rotating shaft of the wind wheel 320 extends into the atomizing chamber 100 and is transmission-connected with the shaft hole of the water wheel 200. The air inlet 332 of the volute 330 is located at the top of the volute 330 and is arranged upward. The air outlet 331 of the volute 330 is located on the peripheral wall of the volute 330 and is the air outlet of the fan 300. Among them, the motor 310 is equipped with a motor cover 311.

Of course, the atomizing chamber 100 can also be provided with a water inlet, etc., and the purpose of this application can also be achieved. Its purpose does not deviate from the design concept of the utility model, and will not be repeated here, and should all fall within the protection scope of this application.
