Description
Technical Field
The invention relates to the air conditioning technology, in particular to an air conditioner indoor unit.
Background
The air-out mode of traditional wall-hanging air conditioning indoor set is mostly air-out down, and this kind of air supply mode can lead to cold wind or hot-blast direct blowing to the human body, is unfavorable for user's comfort level to experience and healthy. The air outlet of the indoor unit of the air conditioner is usually provided with a guide plate so as to adjust the air outlet direction of the air outlet through the up-and-down swinging or the left-and-right swinging of the guide plate. However, this method has a limited adjustment range, and it is difficult to achieve a blowing requirement in a wide range. Even if the fluid is blown upwards or laterally by some unconventional means on the basis of the traditional wall-mounted air conditioner indoor unit, the loss of the wind speed and the wind pressure is large, so that the power consumption of the air conditioner indoor unit is high, and the noise is large.
In order to reduce noise, some of the air conditioning indoor units disclosed in the patent documents disclosed so far simply replace a fan with an ion wind device, however, the speed of the ion wind generated by the ion wind device is extremely limited, and the speed of the replaced air conditioning indoor unit is greatly reduced, which hardly meets the most basic use requirements of users. Due to the defects and impracticality of the existing technical solutions, the technology of blowing air by using ion wind has only remained on the most basic theoretical level.
In order to expand the air supply range, some air conditioning indoor units in the prior art are provided with a pair of air outlets at the left and right ends of the air conditioning indoor unit, and the air outlets at the left and right ends face the left side and the right side of the casing respectively. Although such an air conditioning indoor unit seems to achieve a relatively large air supply range, a wall-mounted air conditioning indoor unit is generally installed on a wall adjacent to a corner in a room, and air supplied through air outlets at left and right ends of the wall-mounted air conditioning indoor unit is generally blown directly onto or away from another wall perpendicular to the wall on which the indoor unit is installed, and both areas do not belong to a normal activity area of a user. Therefore, the actual air supply range of the air conditioning indoor unit is not much different from the air supply range of the conventional air conditioning indoor unit with only the lower air outlet. That is to say, the air conditioner indoor unit not only does not really enlarge the air supply range, but also greatly increases the manufacturing cost and the power consumption because two air outlets are additionally arranged and two fans are additionally arranged. To put it back, even if the installation position of the air-conditioning indoor unit is not considered, the air sent out by the air outlets of the air-conditioning indoor unit is directly blown out towards two opposite directions or mutually perpendicular directions, the air supply ranges of the air outlets are discontinuous and discontinuous, so that the indoor temperature cold and hot are uneven, and the comfort experience of users is seriously influenced.

Referring to fig. 1 to 7, an air conditioning indoor unit 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 casing 10 has an air inlet 120 at a front side thereof and a first lateral air outlet 112 and a second lateral air outlet 113 at two sides of the casing 10 and facing a lateral front of the casing 10, respectively. Specifically, the design of the orientation of each air outlet of the invention can be such that: the air sent out from the first lateral air outlet 112 and the second lateral air outlet 113 is blown to the lateral front of the casing 10, and the air sent out from each air outlet can directly reach the normal moving area of the user, so that the air supply effect of the left front side and the right front side can be achieved, the limitation on the installation position of the indoor unit 1 of the air conditioner is weakened, the air supply angle of the indoor unit 1 of the air conditioner is increased, the air supply range is expanded, and the refrigerating/heating efficiency is improved.
Meanwhile, the special design of the present invention that the air inlet 120 is disposed at the front side of the casing 10 and the heat exchanging device 20, the fan assembly 30 and the two ion wind generating devices are sequentially disposed from front to back not only allows the indoor unit 1 of the air conditioner to be installed at a position where there is no gap between the top of the indoor unit and the ceiling (that is, even if the top of the indoor unit 1 of the air conditioner abuts against the indoor wall, the indoor unit can still normally enter and exit the air), thereby further weakening the limitation on the installation position, improving the installation flexibility, enlarging the use environment, but also the air after heat exchange by the heat exchanger 20 directly flows to the ion wind generator from front to back through a specific wind path, so that the air flow flows linearly as much as possible, the frequency of changing the direction of the air flow is reduced, thereby reducing the flowing resistance of the airflow and improving the air quantity and speed of the air supply of the ion wind generating device.
The heat exchanging device 20 is configured to exchange heat with air flowing therethrough to change the temperature of the air flowing therethrough into cold air or hot air. The fan assembly 30 is configured to promote the air heat exchanged by the heat exchanging device 20 to flow towards the first lateral air outlet 112 and the second lateral air outlet 113 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 promote the air heat-exchanged by the heat exchanging device 20 to flow toward the first lateral wind outlet 112 and the second lateral wind outlet 113, respectively, by an electric field force. That is, the present invention supplies air to the two side air outlets through the fan assembly 30 and the two ion wind generating devices, so that on one hand, the whole air supply amount and the air supply speed of the air conditioner indoor unit 1 are ensured, and on the other hand, the two ion wind generating devices make particles in the air obtain kinetic energy by means of electric field force, thereby forming ion wind. 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. Compared with the condition that the fan is used for supplying air, the invention reduces the whole noise of the air conditioner indoor unit 1 during operation 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 improved.
In summary, the air-conditioning indoor unit 1 of the present invention is designed and reasonably arranged in a special way for the structures and positions of the air inlet, the air outlet, the heat exchange device, the fan assembly and the two ion wind generating devices, and the ion wind blowing technology staying on a theoretical level for a long time is improved in an original way, so that the ion wind blowing technology is perfectly combined with the fan type blowing component, and the technical problems of small blowing range, large noise, poor experience effect, poor appearance effect, etc. existing in the prior art are solved with a simple structure. Meanwhile, the technical scheme of the invention has better realizability and economic value, is an innovation of the air supply form of the air conditioner and has better popularization value.
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.
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. 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.
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 used herein refer to both the interior and exterior of the enclosure 10. 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 circle centers of circles where the first circular arc-shaped curve and the second circular arc-shaped curve are located on the front sides of the respective circular arc-shaped curves, that is, the first circular arc-shaped curve and the second circular arc-shaped curve both have a shape which is convexly curved backward. 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.
In some embodiments of the present invention, referring to fig. 1 and 2, the cabinet 10 includes a rear case 14 for constituting a rear portion thereof and a front panel 13 for constituting a front portion thereof. The front panel 13 is configured to be pivotably 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 an air intake opening 120 of the cabinet 10 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 an 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 air inlet opening 120 of the cabinet 10 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 air inlet 120 of the cabinet 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.
Further, referring to fig. 5 and 6, the rear case 14 may have a body 141 extending vertically and upper and lower edge portions 142 and 143 extending forward from upper and lower sides of the body 141 in a bent manner. The body 141 may be provided with a hanging hole for hanging the indoor unit 1 of an air conditioner on a wall.
In some embodiments of the present invention, the casing 10 further includes two first side air ducts 151 arranged side by side in the front-rear direction and two second side air ducts 152 arranged side by side in the front-rear direction. The first side air guiding ducts 151 and the second side air guiding ducts 152 are respectively located at two lateral ends between the rear shell 14 and the front panel 13, that is, the two first side air guiding ducts 151 and the two second side air guiding ducts 152 are both located in a space defined between the rear shell 14 and the front panel 13 and are respectively located at two lateral ends of the space. 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. The inner side ports of the first and second side air ducts 151 and 152 on the front side are respectively connected to two lateral air outlets (i.e. volute air outlets of two centrifugal fans described later) of the fan assembly 30. Specifically, the first and second side air ducts 151 and 152 may be respectively fixed with the fan assembly 30 at the inner ports thereof by screwing, clipping, or other suitable means. Similarly, the inner side ports of the first side air duct 151 and the second side air duct 152 on the rear side are respectively connected to the two lateral air outlets of the first ion wind generating device 40 and the second ion wind generating device 50.
Further, a first fan wind guiding passage 61 and a first ion wind guiding passage 63 are respectively formed in the two first side wind guiding cylinders 151, and a second fan wind guiding passage 62 and a second ion wind guiding passage 64 are respectively formed in the two second side wind guiding cylinders 152. Specifically, the first fan guide passage 61 may be formed in the first side air guide duct 151 located on the front side, and the first ion guide passage 63 may be formed in the first side air guide duct 151 located on the rear side. The second fan guide duct 62 may be formed in the second side air guide duct 152 on the front side, and the second ion guide duct 64 may be formed in the second side air guide duct 152 on the rear side. Specifically, taking the first side air duct 151 located at the front side as an example, the first side air duct 151 may be a tubular body that is bent and extended along the arc-shaped curve from one of the lateral air outlets (for example, a volute air outlet of the first centrifugal fan 31) of the fan assembly 30 to the first lateral air outlet 112, and the first fan guiding passage 61 is defined in the tubular body. Similarly, the second side air guiding duct 152 at the front side may be a tubular body that is bent and extended along the arc-shaped curve from another lateral air outlet (for example, a volute air outlet of the second centrifugal fan 32) of the fan assembly 30 to the second lateral air outlet 113, and the second fan air guiding passage 62 is defined in the tubular body. This can reduce the thickness of the air conditioning indoor unit 1 in the front-rear direction, thereby further reducing the size of the space occupied by the air conditioning indoor unit.
In some embodiments of the present invention, the fan assembly 30 and the first ion wind generating device 40 and the second ion wind generating device 50 are configured to be selectively activated to operate the indoor unit 1 in a fast cooling/fast heating mode in which the fan assembly 30 is used to drive the air supply or a silent mode in which the first ion wind generating device 40 and the second ion wind generating device 50 are used to drive the air supply. That is to say, the air-conditioning indoor unit 1 can have at least two working modes of rapid cooling/rapid heating and silencing by controlling the start and stop of the fan assembly 30 and the two ion wind generating devices, so that various use requirements of different users or the same user under different conditions are met, and the use experience of the user is improved.
Furthermore, a wind guiding plate (not shown) for controllably conducting and/or blocking the wind guiding channel is respectively disposed in the first fan wind guiding channel 61, the second fan wind guiding channel 62, the first ion wind guiding channel 63, and the second ion wind guiding channel 64. The air deflectors in the first fan air guiding channel 61 and the second fan air guiding channel 62 are configured to be controlled to respectively conduct the first fan air guiding channel 61 and the second fan air guiding channel 62 in a fast cooling/fast heating mode, and to respectively block the first fan air guiding channel 61 and the second fan air guiding channel 62 in a mute mode. The air guiding plates in the first ion air guiding channel 63 and the second ion air guiding channel 64 are configured to be controlled to respectively conduct the first ion air guiding channel 63 and the second ion air guiding channel 64 in a mute mode, and to respectively block the first ion air guiding channel 63 and the second ion air guiding channel 64 in a fast cooling/fast heating mode. Therefore, the phenomenon that an unexpected air path is formed inside the machine shell 10 or air flow leaks outside under any mode can be avoided, so that certain pressure can be formed inside the machine shell 10 under two modes, and the air speed and the air volume of the corresponding air outlet are improved.
Specifically, in the rapid cooling/rapid heating mode, the two ion wind generation devices are not started to operate, and the indoor unit of the air conditioner drives and supplies air to the two side air outlets simultaneously only through the fan assembly 30. Since the fan assembly 30 has a relatively large air supply amount and a relatively high cooling efficiency or heating efficiency, the indoor temperature can be rapidly relieved. This mode is suitable for the case where the air conditioning indoor unit 1 starts to operate or other cases where rapid cooling or heating is required. In a silent mode, the fan assembly 30 is not started to operate, and the indoor unit of the air conditioner drives the air supply to the two side air outlets only through the two ion air generating devices respectively, so that on one hand, the air is supplied through the two side air outlets simultaneously, the air supply range is expanded, and the air supply quantity is increased; on the other hand, the working noise of the ion wind generating device in operation is close to or even lower than the indoor background noise, the integral noise of the indoor unit 1 of the air conditioner in operation is greatly reduced, and the industrial problem of ultra-low silence air supply is solved. The mode is suitable for use environments such as medical treatment and child monitoring, and the situation that the indoor unit 1 of the air conditioner runs for a period of time.
Of course, in other embodiments of the present invention, the indoor unit 1 may have a high-speed air supply mode in addition to the rapid cooling/rapid heating mode and the mute mode. In this mode, the fan assembly 30 and the two ion wind generating devices can be controlled to start and operate simultaneously to supply wind to the two side wind outlets simultaneously. The mode is suitable for the situations of more rapid cooling or rapid heating and other situations with higher requirements on wind speed.
In some embodiments of the present invention, referring to fig. 4-6, the fan assembly 30 includes two centrifugal fans, such as a first centrifugal fan 31 and a second centrifugal fan 32, disposed side by side in the transverse direction. The first centrifugal fan 31 and the second centrifugal fan 32 may be forward-direction centrifugal fans or backward-direction centrifugal fans. The heat exchange device 20 is a flat plate evaporator to improve heat exchange efficiency and reduce the thickness of the indoor unit 1 in the front-rear direction, thereby reducing the volume of the indoor unit 1. The width of the evaporator in the transverse direction is approximately equal to the sum of the widths of the two centrifugal fans in the transverse direction, so that the air subjected to heat exchange by the evaporator flows into the air ducts of the two centrifugal fans.
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.
In some embodiments of the invention, the fan assembly 30 further includes a rear liner 34 attached to the rear of the two centrifugal fans, which together with the volutes of the centrifugal fans defines the wind path of the centrifugal fans. The rear liner 34 is provided with vent holes 341 in the area opposite to the air inlet of each centrifugal fan and the area opposite to the gap between the volutes of the two centrifugal fans, so that the air heat-exchanged by the heat exchanging device 20 passes through and flows to the first ion wind generating device 40 and the second ion wind generating device 50. Specifically, the first centrifugal fan 31 and the second centrifugal fan 32 have their respective volutes and centrifugal impellers accommodated in the volutes, respectively. An air inlet is formed in one side, facing the heat exchange device 20, of the volute, the rear lining plate 34 is arranged on one side, facing away from the heat exchange device 20, of the volute, and the rear lining plate 34 and the volutes of the two centrifugal fans jointly form an air channel of the fan assembly 30.
The air outlet of the volute 311 of the first centrifugal fan 31 and the air outlet of the volute 321 of the second centrifugal fan 32 face away from each other toward the two lateral sides of the casing 10. Specifically, the air outlet of the volute 311 of the first centrifugal fan 31 faces the left side of the casing 10, i.e. the side where the first lateral air outlet 112 is located, and the air outlet of the volute 321 of the second centrifugal fan 32 faces the right side of the casing 10, i.e. the side where the second lateral air outlet 113 is located. The volute 311 of the first centrifugal fan 31 and the volute 321 of the second centrifugal fan 32 are independent from each other, so that the airflows blowing to the first lateral air outlet 112 and the second lateral air outlet 113 are independent from each other and do not affect each other, thereby avoiding airflow disorder.
When the air conditioning indoor unit 1 is driven by the fan assembly 30 to supply air, under the driving of the centrifugal impeller, ambient air flows to the heat exchanging device 20 through the air inlet 120, cold air or hot air after heat exchange by the heat exchanging device 20 enters the air duct of the fan assembly 30 through the volute air inlets of the first centrifugal fan 31 and the second centrifugal fan 32, and finally flows to the first lateral air outlet 112 and the second lateral air outlet 113 through the volute 311 air outlet of the first centrifugal fan 31 and the volute 321 air outlet of the second centrifugal fan 32, so that the air outlet effect of the left front side and the right front side in an encircling manner is achieved.
When the air conditioning indoor unit 1 is driven by only two ion wind generating devices to supply air, under the action of an electric field force, ambient air flows to the heat exchanging device 20 through the air inlet 120, directly flows to the first ion wind generating device 40 and the second ion wind generating device 50 through the vent 341 on the rear liner 34, and respectively flows to the first lateral air outlet 112 and the second lateral air outlet 113 under the action of the electric field force, so that the effect of surrounding air supply on the left front side and the right front side is achieved. At this time, the centrifugal impeller of the fan assembly does not produce any driving action.
Therefore, the structure of the fan assembly 30 is specially designed, so that a special air flow path with a short path and a smooth trend can be provided for the ion wind generating device 40 when the ion wind generating device drives the air supply independently, the structure of the air-conditioning indoor unit 1 is simplified, and the volume of the air-conditioning indoor unit is reduced.
Fig. 8 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. 8, 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. 9 is a schematic cross-sectional view of a discharge module according to an embodiment of the present invention. With reference to figure 9 of the drawings,in order to increase the blowing speed of the ion wind generating apparatus, the designer of the present invention has performed a large number of wind speed measurement experiments, and as a result of the experiments, it has been found that the distance L between the tip of each discharge needle 412 and the metal mesh 411 is set so as 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 needle point of the discharge needle 412 and the metal mesh 411, and the wind speed center point of the metal mesh 411 is the projection point of the needle point 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 of the metal mesh 411 generating 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. 6, each discharge module 410 further includes a housing 414 having at least four peripheral wall panels, wherein the wall panel opposite to the front surface of the fan assembly 30 is provided with a plurality of uniformly arranged air inlet holes 4141. Each discharge module 410 further includes a plurality of metal conductive bars 413. Each of the metal conductive bars 413 has an insulating protective layer formed on the outside thereof and a conductive layer formed on the inside thereof, which is electrically connected to the metal discharge needles 412.
Specifically, the plurality of discharge needles 412 are uniformly distributed on the outer side of the metal conductive strip 413 facing the metal mesh 411. The outer surface of each metal conductive bar 413 is provided with a plurality of pinholes for installing 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 and the conductive layer in the metal conductive bar 413 are kept in good electrical connection, and simultaneously, the conductive layer can be strictly prevented from being exposed to the outside, thereby avoiding the phenomena of random discharge or sparking.
