Detailed Description
The embodiment of the invention provides an air conditioner indoor unit. Fig. 1 is a schematic configuration view of an air conditioning indoor unit according to one embodiment of the present invention, fig. 2 is a schematic side view of the air conditioning indoor unit according to one embodiment of the present invention, fig. 3 is a schematic front view of the air conditioning indoor unit according to one embodiment of the present invention, fig. 4 is a schematic cross-sectional view taken along a sectional line B-B in fig. 3, fig. 5 is a schematic structural exploded view of the air conditioning indoor unit according to one embodiment of the present invention, and fig. 6 is a schematic cross-sectional view taken along a sectional line a-a in fig. 3. Referring to fig. 1 to 6, an air conditioning indoor unit 1 according to an embodiment of the present invention includes a casing 10, a heat exchanging device 20 disposed in the casing 10, a fan assembly 30 disposed at a rear side of the heat exchanging device 20, and a first ion wind generating device 40 and a second ion wind generating device 50.
The cabinet 10 has a first intake vent 121 located at an upper portion of a rear side thereof, a second intake vent 122 located at a front side of the cabinet 10, and a first lateral air outlet 112 and a second lateral air outlet 113 located at both sides of the cabinet 10, respectively. Specifically, in some embodiments of the present invention, the first and second lateral air outlets 112 and 113 may face both lateral sides of the cabinet 10. In some preferred embodiments of the present invention, the first and second lateral outlets 112 and 113 may face a lateral front of the cabinet 10. Accordingly, the wind sent out through the first and second lateral outlets 112 and 113 is blown toward the lateral front of the cabinet 10. That is, the air sent out from each air outlet can directly reach the normal moving area of the user, thereby forming the effect of air supply from the left front side and the right front side, weakening the limit on the installation position of the indoor unit 1 of the air conditioner, increasing the air supply angle of the indoor unit 1 of the air conditioner, enlarging the air supply range and improving the cooling/heating efficiency.
The heat exchanging device 20 is configured to exchange heat with air flowing therethrough to change the temperature of the air flowing therethrough into heat exchanging air (cold air or hot air). The fan assembly 30 is configured to cause the natural air entering from the second air inlet 122 to flow to the heat exchanging device 20, and to cause the heat exchanged air after heat exchange by the heat exchanging device 20 to flow towards the first lateral air outlet 112 and the second lateral air outlet 113 via the air duct of the fan assembly 30, respectively. The first ion wind generating device 40 and the second ion wind generating device 50 are laterally disposed at the rear side of the fan assembly 30 side by side, and are configured to induce the natural air entering from the first air inlet 121 to directly flow to the first lateral air outlet 112 and the second lateral air outlet 113 via the first ion wind generating device 40 and the second ion wind generating device 50, respectively, by an electric field force, so that the natural air and the heat exchange air after heat exchange by the heat exchange device 20 are mixed at the first lateral air outlet 112 and the second lateral air outlet 113. It should be emphasized that the natural air referred to in the present invention means air that has not been heat-exchanged by the heat exchanging device 20, i.e. the ambient air of the ambient space where the indoor unit 1 of the air conditioner is located. The heat exchange air referred to in the present invention means air after heat exchange by the heat exchange device 20, and when the indoor unit 1 of the air conditioner is in a heating mode, the heat exchange air may be hot air, and when the indoor unit 1 of the air conditioner is in a cooling mode, the heat exchange air may be cold air.
After the partial heat exchange air after the heat exchange of the heat exchange device 20 and the natural air which is not subjected to the heat exchange of the heat exchange device 20 are mixed at the two lateral air outlets, soft, uniform and comfortable mixed air can be formed. The mixed air only enables the user to feel cool but not cold, warm but not hot comfortable experience, and does not bring sensory stimulation to the user or damage the physical health of the user. For example, in summer, when the indoor temperature of the air-conditioning indoor unit 1 is 26 to 35 ℃ for cooling, the temperature of the cooling air blown out is about 18 ℃. However, after natural air and 18 ℃ refrigerating air are mixed through the ion wind generating device, the outlet air temperature can be raised to about 23 ℃, and the 23 ℃ refrigerating wind is softer and more comfortable than the 18 ℃ refrigerating wind and is closer to the comfort degree of a human body. Meanwhile, the air sent out by the two lateral air outlets can form the effect of air supply on the left front side and the right front side, so that the impact of local high-speed cold air flow is reduced, and the air supply range of the indoor unit 1 of the air conditioner is expanded.
Meanwhile, the air-conditioning indoor unit 1 of the invention is driven by the fan assembly 20 to send out heat exchange air, and is driven by the single ion air generating device to introduce natural air, so that on one hand, the air-conditioning indoor unit 1 is ensured to have larger integral air quantity and air speed, the requirement of indoor integral refrigerating capacity is met on the premise of ensuring the comfort of users, the balance of indoor temperature is ensured, and the refrigerating/heating efficiency and the refrigerating/heating effect of the air-conditioning indoor unit 1 are improved; on the other hand, the ion wind generating device relies on the electric field force to make the particles in the air obtain kinetic energy, so as to form soft, uniform and comfortable ion wind without local high-speed airflow (since the generating principle of the ion wind is easily obtained and known by those skilled in the art, the description is omitted here). Compared with a rotary air supply assembly (such as a fan), the ion wind generating device has the advantages of pressure loss, low energy consumption, low noise and the like, so that the overall noise of the air conditioner indoor unit 1 during operation is reduced to a certain extent. Meanwhile, the ion wind generated by the ion wind generating device is not generated by pressure, but is a soft wind close to nature generated by electric field force, so that the comfort level of the air-conditioning indoor unit 1 can be further improved.
In addition, it should be noted that, according to the present invention, the first air inlet 121 is disposed at the upper portion of the rear side of the casing 10, the second air inlet 122 is disposed at the front side of the casing 10, and the heat exchanging device 20, the fan assembly 30 and the ion wind generating device 40 are sequentially arranged from front to back, such that the distance between the first air inlet 121 and the second air inlet 122 can be increased, thereby preventing the natural air flowing from the first air inlet 121 to the two ion wind generating devices and the natural air flowing from the second air inlet 122 to the heat exchanging device 20 from interfering with each other or generating phenomena such as mixed flow and turbulent flow, and further reducing airflow resistance, increasing the air inlet speed and the air inlet volume of the indoor air conditioner 1, and further increasing the air supply speed and the air supply volume of the indoor air conditioner 1.

Further, the rear liner 34 abuts against the upper portion of the casing 10 to separate the natural air flowing from the first air inlet 121 to the first ion wind generating device 40 and the second ion wind generating device 50 from the natural air flowing from the second air inlet 122 to the heat exchanging device 20. Therefore, mutual interference between the natural air flowing to the two ion wind generating devices and the natural air flowing to the heat exchange device 20 can be avoided, phenomena such as turbulent flow, turbulent flow or mixed flow are avoided, the air inlet speed of the indoor unit 1 of the air conditioner is increased, and the air outlet speed of the indoor unit is increased.
In some alternative embodiments of the present invention, the inner side of the top wall of the cabinet 10 may be provided with a partition wall, which may extend vertically downward from a position between the first air inlet 121 and the second air inlet 122 to a position between the first ion wind generating device 40 and the heat exchanging device 20 and between the second ion wind generating device 50 and the heat exchanging device 20 or to a rear side of the air inlets of the first ion wind generating device 40 and the second ion wind generating device 50.

The outer ports of the two first side air ducts 151 and the two second side air ducts 152 form a first side air outlet 112 and a second side air outlet 113, respectively. That is, the outer ports of the two first side air ducts 151 form the first side air outlet 112 together, and the outer ports of the two second side air ducts 152 form the second side air outlet 113 together.
It is emphasized that the outside ports of the first and second side wind scoops 151 and 152 mean their respective ports exposed to the outside of the cabinet 10, and accordingly, the first and second side wind scoops 151 and 152 also have inside ports hidden inside the cabinet 10, respectively.
Further, a fixing bracket 80 for fixing the heat exchanging device 20 may be disposed between the fan assembly 30 and the heat exchanging device 20, and the heat exchanging device 20 and the fixing bracket 80, and the fixing bracket 80 and the rear housing 14 may be fixed together by screw connection, clamping connection, or other suitable connection methods.

The inner side ports of the first side air duct 151 and the second side air duct 152 on the front side are respectively connected to two lateral air duct outlets of the fan assembly 30, so as to form a first sealed air duct between the second air inlet 122, the heat exchanging device 20, the fan assembly 30, the first side air duct 151 on the front side and the second side air duct 152 on the front side. The inner side ports of the first side air duct 151 and the second side air duct 152 at the rear side are respectively connected to the air outlets of the first ion wind generating device 40 and the second ion wind generating device 50, so that a second sealed air duct completely separated and independent from the first sealed air duct is formed among the first air inlet 121, the first ion wind generating device 40, the second ion wind generating device 50, the first side air duct 151 at the rear side, and the second side air duct 152 at the rear side. Therefore, heat exchange air inside the indoor unit 1 of the air conditioner and natural air are not interfered with each other and not influenced with each other, and therefore the condition that disturbance is generated among air flows to influence the flow direction and the flow speed of the air flows is avoided.
Specifically, two lateral air duct outlets of the air duct of the fan assembly 30 are respectively used for supplying air to front portions of the first lateral air outlet 112 and the second lateral air outlet 113, and the two lateral air duct outlets can be respectively volute air outlets of the first centrifugal fan 31 and the second centrifugal fan 32. The air outlets of the first ion wind generating device 40 and the second ion wind generating device 50 are respectively used for supplying air to the rear parts of the first lateral air outlet 112 and the second lateral air outlet 113. Specifically, the first side air duct 151 and the second side air duct 152 on the front side may be respectively fixed to the fan assembly at the inner ports thereof by screws, clamping, or other suitable means, and the first side air duct 151 and the second side air duct 152 on the rear side may be respectively fixed to the two ion wind generating devices at the inner ports thereof by screws, clamping, or other suitable means.
In some embodiments of the present invention, referring to fig. 5, the rear case 14 has a body 141 extending vertically, and upper and lower edges 142 and 143 extending forward from upper and lower sides of the body 141. The first air inlet 121 is formed in the upper edge portion 142. This simplifies the structure of the housing 10 and makes the whole housing more beautiful. Specifically, the body 141 may be provided with a hanging hole for hanging the indoor unit 1 of the air conditioner on a wall. The first air inlet 121 may include a plurality of uniformly distributed vent holes to ensure the uniformity of the inlet air.
Further, referring to fig. 2, the front panel 13 is configured to be pivotally connected to the front side of the rear housing 14 in the front-rear direction about its bottom pivot axis extending in the lateral direction to form a second air intake opening 122 between the front panel 13 and the rear housing 14 when the front panel 13 is controllably pivoted forward about its bottom pivot axis to the open position.
Specifically, the bottom of the front panel 13 is pivotably connected to the bottom front side of the rear housing 14 in the front-rear direction, and the front panel 13 is configured to be controllably pivoted between its open position and closed position. When the air conditioning indoor unit 1 is started, the front panel 13 is controllably pivoted forward about its bottom pivot axis to the open position, so that the second air intake opening 122 is formed at the upper portion and both lateral side portions between the front panel 13 and the rear casing 14. When the front panel 13 is controllably pivoted backward about its bottom pivot axis to the closed position after the air conditioning indoor unit 1 stops operating, the circumferential edge of the front panel 13 abuts against at least a part of the circumferential edge of the rear casing 14 and the edges of other components, so that the second air inlet 122 of the casing 10 disappears. Therefore, the front panel 13 is specially designed, so that a normal air inlet can be formed at the front side of the air-conditioning indoor unit 1 when the air-conditioning indoor unit 1 operates, and the shell 10 of the air-conditioning indoor unit 1 can form a whole with a compact structure and a uniform appearance when the air-conditioning indoor unit 1 stops operating, so that the occupied space of the air-conditioning indoor unit 1 in a non-operating state is reduced, and the appearance effect of the air-conditioning indoor unit is improved.
In some embodiments of the present invention, referring to fig. 4 and 5, the air conditioning indoor unit 1 further includes a first fan air guiding passage 61, a second fan air guiding passage 62, a first ion air guiding passage 63, and a second ion air guiding passage 64. The first fan guiding duct 61 and the second fan guiding duct 62 respectively extend from two lateral sides of the fan assembly 30 to the front portions of the first lateral air outlet 112 and the second lateral air outlet 113 in a bending manner, so as to respectively guide air flowing to the first lateral air outlet 112 and the second lateral air outlet 113 through the air duct of the fan assembly 30. The first ion wind guiding channel 63 and the second ion wind guiding channel 64 respectively extend from the lateral outer ends of the first ion wind generating device 40 and the second ion wind generating device 50 to the rear portions of the first lateral wind outlet 112 and the second lateral wind outlet 113, so as to respectively guide the air flowing to the first lateral wind outlet 112 via the first ion wind generating device 40 and the air flowing to the second lateral wind outlet 113 via the second ion wind generating device 50. That is, the first fan guiding duct 61 and the second fan guiding duct 62 are respectively communicated with the front half parts of the first lateral air outlet 112 and the second lateral air outlet 113, and the first ion guiding duct 63 and the second ion guiding duct 64 are respectively communicated with the rear half parts of the first lateral air outlet 112 and the second lateral air outlet 113. Therefore, the air sent out from the two lateral air outlets can be blown to the left front side and the right front side of the shell, and independent air supply channels which are not influenced mutually can be formed between the fan assembly 30 and the ion wind generating device. The air conditioner indoor unit 1 can further ensure that an encircling air supply effect is formed, the resistance in the air flow flowing process can be reduced, and the air speed and the air volume of the two lateral air outlets are improved.
Specifically, the first and second fan guide air passages 61 and 62 may be respectively formed in the first and second side air funnels 151 and 152 at the front side, and the first and second ion air guide passages 63 and 62 may be respectively formed in the first and second side air funnels 151 and 152 at the rear side.
In some embodiments of the present invention, the first fan guiding air passage 61 and the first ion guiding air passage 63 are both in a cylindrical shape, the first fan guiding air passage 61 extends along a first circular arc-shaped curve from inside to outside, and the first ion guiding air passage 63 extends along a second circular arc-shaped curve from inside to outside. It will be understood by those skilled in the art that the terms "inner" and "outer" as referred to herein mean the interior and exterior of the enclosure 10, respectively. The second fan air guide channel 62 and the first fan air guide channel 61 are symmetrically arranged, and the second ion air guide channel 64 and the first ion air guide channel 63 are symmetrically arranged.
Further, the center of the circle of the first circular arc-shaped curve is located on the front side of the first circular arc-shaped curve, and the center of the circle of the second circular arc-shaped curve is located on the front side of the second circular arc-shaped curve. That is, each of the first circular arc-shaped curve and the second circular arc-shaped curve has a shape convexly curved rearward. Therefore, airflow can flow more smoothly, airflow resistance is further reduced, and the air speed and the air volume of the lateral air outlet are improved; and the first lateral air outlet 112 and the second lateral air outlet 113 can more easily form a looping air supply effect, so that the indoor unit 1 of the air conditioner is ensured to have the best comfort level.
Furthermore, the radius of the circle on which the first circular arc-shaped curve is positioned is larger than that of the circle on which the second circular arc-shaped curve is positioned. That is, the second circular arc-shaped curve has a shape convexly curved more rearward than the first circular arc-shaped curve. Therefore, the forward inclination degree of the natural air which is sent out by the two lateral air outlets and guided by the first ion air guiding channel 63 and the second ion air guiding channel 64 is larger than the forward inclination degree of the heat exchange air which is sent out by the two lateral air outlets and guided by the first fan air guiding channel 61 and the second fan air guiding channel 62, so that the natural air at the rear side and the heat exchange air at the front side are more favorably mixed in a cross mode, and the mixing effect of the two kinds of air is better.
In some alternative embodiments of the invention, the first circular arc shaped curve is located at the center of a circle at the rear side of the first circular arc shaped curve, and the second circular arc shaped curve is located at the center of a circle at the front side of the second circular arc shaped curve. That is, the first circular arc-shaped curve has a forwardly convexly curved shape, and the second circular arc-shaped curve has a rearwardly convexly curved shape. As a result, the heat exchange air guided through the first fan air guiding passage 61 and the second fan air guiding passage 62 can be blown obliquely rearward, and the natural air guided through the first ion air guiding passage 63 and the second ion air guiding passage 64 can be blown obliquely forward, so that the heat exchange air and the natural air can be mixed more favorably.
In some embodiments of the present invention, referring to fig. 3, an inner side edge 1121 of the first lateral air outlet 112, which is close to a vertical bisecting plane S extending in the front-rear direction of the air conditioning indoor unit 1, is located more forward than an outer side edge 1122 of the first lateral air outlet 112, which is far from the vertical bisecting plane S, so that the first lateral air outlet 112 faces the outer side front of the casing 10. That is, the inner edge 1121 and the outer edge 1122 of the first lateral air outlet 112 are located at different positions in the lateral direction and the front-rear direction, the inner edge 1121 is closer to the vertically bisected plane of the air conditioning indoor unit 1 extending in the front-rear direction than the outer edge 1122 thereof, and the inner edge 1121 is located laterally forward of the outer edge 1122 thereof, so that the first lateral air outlet 112 is directed obliquely outward toward the front of the cabinet.
Further, the second lateral air outlet 113 and the first lateral air outlet 112 are symmetrically disposed. That is, the inner edge 1131 of the second lateral outlet 113 is more forward than the outer edge 1132 of the second lateral outlet 113. In other words, the inside edge 1131 and the outside edge 1132 of the second lateral air outlet 113 are located at different positions in the lateral direction and the front-rear direction, the inside edge 1131 is closer to the vertical bisecting plane S of the indoor unit 1 extending in the front-rear direction than the outside edge 1132, and the inside edge 1131 is located laterally forward of the outside edge 1132, so that the second lateral air outlet 113 faces obliquely outward toward the front of the cabinet.
Therefore, the two lateral air outlets of the indoor air conditioner 1 can respectively supply air towards the front of the transverse outer side of the casing 10 to form an encircling air supply effect, so that the air supply range of the indoor air conditioner 1 is further expanded, cold air or hot air is prevented from directly blowing to a human body, the uniformity of indoor temperature is improved, the comfort level of the indoor air conditioner 1 is further improved, and the use experience of a user is better.
Fig. 7 is a schematic exploded view of a discharge module of the ion wind generating device according to an embodiment of the present invention. In some embodiments of the present invention, referring to fig. 7, each of the first ion wind generating device 40 and the second ion wind generating device 50 includes at least one discharge module 410. Each discharge module 410 has a metal mesh 411 and a plurality of discharge needles 412 located inside the metal mesh 411 and arranged in an array. The needle point of the discharge needle 412 is close to the metal net 411, positive and negative high voltage electrodes are respectively applied on the discharge needle 412 and the metal net 411, the discharge needle 412 is equivalent to a radiation electrode for generating corona discharge, and the metal net 411 is equivalent to a receiving electrode.
It should be emphasized that the inner side referred to herein means a side of the metal net 411 toward the geometric center of the cabinet 10, and the outer side opposite to the inner side means a side of the metal net 411 toward the outside of the cabinet 10. That is, the flow direction of the ion wind generated by each discharge module 410 is from the inside to the outside, and the arrangement direction of the plurality of discharge needles 412 and the metal mesh 411 is the same as the flow direction of the ion wind.
Fig. 8 is a schematic cross-sectional view of a discharge module according to an embodiment of the present invention. Referring to fig. 8, in order to increase the blowing speed of the ion wind generating apparatus, the designer of the present invention has performed a number of wind speed measurement experiments, and as a result of the experiments, it was found that the distance L between the tip of each discharge needle 412 and the metal mesh 411 is set to satisfy L ═ aL1(wherein a is any constant in the range of 0.7-1.3, i.e. a can be 0.7, 0.8, 0.9, 1.0, 1.1, 1.2 or 1.3, L1So that the wind speed of the ion wind at the wind speed center point of the metal mesh 411 reaches the maximum wind speed VmaxThe distance between the tip of the discharge needle 412 and the metal mesh 411, the metal mesh 4The wind speed center point of 11 is the projection point of the needle tip of the discharge needle 412 on the metal mesh 411), on the one hand, the wind speed of the ion wind generated by the two ion wind generating devices can better meet the normal use requirement of a user, and on the other hand, the discharge needle 412 can be partially overlapped in the area where the metal mesh 411 generates effective ion wind to achieve the projection effect of the shadowless lamp, so that the ion wind distribution of the metal mesh 411 is more uniform.
In order to increase the amount of air supplied to the ion wind generating apparatus, the designer of the present invention has performed a large number of experiments for measuring the projection radius of the tips, and as a result of the experiments, it has been found that the distance R between the tips of two adjacent discharge needles 412 is set to satisfy the requirement of R ═ aR1(wherein, R1For the wind speed to reach the maximum wind speed VmaxB times the distance between the wind speed measuring point and the wind speed central point, wherein b is any constant in the range of 0.3-0.7, namely b can be 0.3, 0.4, 0.5, 0.6 or 0.7, and the value of a is the same as the above), the air volume of the ion wind generated by the two ion wind generating devices can better meet the normal use requirement of a user. Meanwhile, after the distance between two adjacent discharge needles 412 is specially designed, the mutual offset of wind speeds caused by too close distance between two adjacent discharge needles 412 can be avoided, and the reduction of wind volume and the uneven distribution of wind volume caused by too far distance between two discharge needles 412 can be avoided.
Therefore, the ion wind generating device can generate the ion wind with uniform and large wind quantity by reasonably designing the spatial position relationship between the discharge needles 412 and the metal mesh 411 and reasonably arranging the position relationship between the discharge needles 412, so that the wind speed, the wind quantity and the wind efficiency of the ion wind generating device are improved.
In some embodiments of the present invention, each of the first ion wind generating device 40 and the second ion wind generating device 50 includes a plurality of discharge modules 410 arranged in sequence and connected in parallel or in series, and each of the discharge modules 410 has a metal mesh 411 and a plurality of discharge needles 412 located inside the metal mesh 411 and arranged in an array. Therefore, a corona discharge phenomenon is generated between the discharge needle 412 in each discharge module 410 and the corresponding metal mesh 411, so that the ion wind can be accelerated for multiple times through the plurality of discharge modules 410, the superposition of the wind speed can be realized, and the higher wind outlet speed can be obtained. And negative pressure can be formed under the action of high-speed air outlet, so that the air inlet volume is further increased, and the air supply speed, the air supply volume and the air supply efficiency of the multi-stage ion air supply module are improved.
In some embodiments of the present invention, the discharge needles 412 of two adjacent discharge modules 410 are arranged in a straight pair, that is, the projections of the discharge needles 412 of each two adjacent discharge modules in the air outlet plane of the ion wind generating device coincide. Therefore, a larger and stronger electric field is generated in the region corresponding to the tip of each discharge needle 412, so that an ion wind with a higher local wind speed is generated in the region, and the ion wind blows on the user body and has a stronger wind feeling. In other words, this arrangement can obtain a local large wind speed near each wind speed center point of the metal mesh 411, so as to improve the wind feeling when the air-conditioning indoor unit 1 is driven by the ion wind generating device to supply wind alone.
In some alternative embodiments of the present invention, the discharge needles 412 of two adjacent discharge modules 410 are arranged in a staggered manner. One of the dislocation arrangement modes is as follows: the discharge needles 412 of every two adjacent discharge modules are arranged in a staggered manner in a direction perpendicular to the air outlet surface of the ion wind generating device 10, and the projections of the corresponding discharge needles 412 of every two adjacent discharge modules in the air outlet surface of the ion wind generating device 10 are on the same horizontal line (i.e., the discharge needles 412 of every two adjacent discharge modules are arranged in a staggered manner, but the heights of the corresponding discharge needles 412 are the same). Therefore, uniform soft wind can be generated in a plurality of linear regions in the horizontal direction, and the superposition of a plurality of discharge modules can form a larger and stronger electric field in the linear regions, so that the wind speed of the ion wind in the linear regions is relatively higher. Further, the projections of each group of three adjacent discharge needles formed by the discharge needles 412 of the plurality of discharge modules in the horizontal plane all form an isosceles triangle, so as to ensure that the ion wind generated by the ion wind generating device is distributed uniformly.
Another staggered arrangement mode is as follows: the discharge needles 412 of every two adjacent discharge modules are arranged in a staggered manner in the direction perpendicular to the air outlet surface of the ion wind generating device and in the vertical direction. Therefore, the ion wind generated by the ion wind generating device can be uniformly distributed in the wind outlet surface of the ion wind generating device, so that soft, uniform and large-wind-volume air supply can be realized under the conditions of low voltage, low electric field intensity and low power. That is, the discharge needles 412 of each two adjacent discharge modules 410 are staggered from each other, so that the gaps between the discharge needles 412 of each discharge module 410 can be filled. Accordingly, relatively uniform ion wind can be formed in the entire area of the expanded metal 411, and the entire amount of wind can be increased. Further, the projections of each group of three adjacent discharge needles formed by the discharge needles 412 of the plurality of discharge modules in the air outlet surface of the ion wind generating device all form an equilateral triangle, so as to ensure that the ion wind generated by the ion wind generating device is distributed more uniformly.
In some embodiments of the present invention, referring to fig. 7, each discharge module 410 further includes a housing 416, a conductive metal strip 413 having a plurality of conductive metal strips 414, and at least one PCB multi-layer board 415 electrically connected to the conductive metal strip 413 and perpendicular to the conductive metal strip 413. The upper end of the housing 416 is hollowed out or provided with a vent hole for air to enter the housing 416. The PCB multi-layer board 415 has front and rear insulating protective layers and a conductive layer between the two insulating protective layers, and the conductive layer is electrically connected to the conductive metal sheet 414. The bottom wall of the housing 416 is opened with a buckle 4161, and the metal conductive sheet 414 of the metal conductive strip 413 is buckled in the buckle 4161 of the housing 416.
The number of PCB multi-layer boards 415 may be one, which is substantially rectangular; or the number of PCB multi-layer boards 415 may be plural, each PCB multi-layer board 415 having an elongated strip shape extending perpendicular to the metal conductive strips 413.
The plurality of discharge needles 412 are uniformly distributed on the outer side of the at least one PCB multi-layer board 415 facing the metal mesh 411. Specifically, each PCB multi-layer board 415 is provided with a plurality of pin holes on the outer surface thereof for mounting the discharge needles 412. The aperture of the pinhole is slightly smaller than the diameter of the discharge needle 412 so that the pinhole is in interference fit with the discharge needle 412. The filling layer filled by the welding process is arranged around the pin hole inserted into the discharge needle 412, that is, the filling layer filled by the welding process is arranged around the discharge needle 412 of the pin hole, so as to ensure that the discharge needle 412 is well electrically connected with the conductive layer in the PCB multi-layer board 415, and simultaneously, the conductive layer can be strictly prevented from being exposed to the outside, thereby avoiding the phenomena of random discharge or sparking.
