Detailed Description
The embodiment of the invention provides an air conditioner indoor unit. Fig. 1 is a schematic structural view of an air conditioning indoor unit according to one embodiment of the present invention, fig. 2 is a schematic bottom view of the air conditioning indoor unit according to one embodiment of the present invention, fig. 3 is a schematic structural exploded view of the air conditioning indoor unit according to one embodiment of the present invention, and fig. 4 is another schematic structural exploded view of the air conditioning indoor unit according to one embodiment of the present invention. Referring to fig. 1 to 4, 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 in front of the heat exchanging device 20, and an ion wind generating device 40 disposed in front of the fan assembly 30.
The cabinet 10 has a first intake vent 121 and a second intake vent 122 located at an upper portion thereof and arranged in front and rear, a lower outlet vent 111 located at a lower portion of the cabinet 10, and a first lateral outlet 112 and a second lateral 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 blown out through the first and second lateral outlets 112 and 113 is blown toward the lateral front of the cabinet 10, and the wind blown out through the lower outlet 111 is blown toward the lower 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, the right and the lower surfaces, 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 lower air outlet 111, the first lateral air outlet 112 and the second lateral air outlet 113 via the air duct of the fan assembly 30. The ion wind generating device 40 is configured to cause the natural air entering from the first air inlet 121 to directly flow to the lower air outlet 111 via the ion wind generating device 40 by an electric field force, so that the natural air is mixed with a part of the heat-exchanged air after heat exchange by the heat exchanging device 20 at the lower air outlet 111. 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 heat exchange air after the heat exchange of the heat exchange device 20 is partially mixed with the natural air which is not subjected to the heat exchange of the heat exchange device 20 at the lower air outlet 111, soft, uniform and comfortable mixed air can be formed. Even if the mixed air is directly blown to the user, the user can only feel cool but not cold or warm but not hot comfortable experience, and sensory stimulation cannot be brought to the user or the physical health of the user is not damaged. 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 is mixed with the 18 ℃ refrigerating air by the ion wind generating device 40, 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, another part of the heat exchange air after heat exchange by the heat exchange device 20 is blown out through the first lateral air outlet 112 and the second lateral air outlet 113, and is not directly blown to the user to cause discomfort, and can be matched with the lower air outlet to form an effect of air outlet from the left side, the right side and the lower side, so that the impact of local high-speed cold airflow 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 40 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 40 utilizes the electric field force to make the particles in the air obtain kinetic energy, so as to form a soft, uniform and comfortable ion wind without local high-speed airflow (since the generation 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 40 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 40 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 two air inlets are disposed at the upper portion of the casing 10, and the ion wind generating device 40, the fan assembly 30 and the heat exchanging device 20 are sequentially disposed from front to back, such that the thickness of the indoor unit 1 of the air conditioner in the front-back direction can be reduced, so as to reduce the volume of the indoor unit 1 of the air conditioner during the standing and the working operation, so as to meet the high requirements of the user on the installation space and the use space of the indoor unit 1 of the air conditioner, and improve the overall appearance of the indoor unit 1 of the air conditioner, and the distance between the natural air flowing to the lower air outlet 111 through the ion wind generating device 40 and the part of the heat exchanging air flowing to the lower air outlet 111 through the heat exchanging device 20 can be reduced, so that the natural air and the.
In summary, the air-conditioning indoor unit 1 according to the embodiment 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 exchanging device 20, the fan assembly 30, and the ion wind generating device 40, and the ion wind blowing technology staying on the 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, and the like 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.
The ion wind generating device 40 ionizes air to generate a large amount of charged particles, which adsorb solid particles, dust, pollutants, or the like, and then move in a certain direction by an electric force. The ion wind is formed by high voltage electric field, so it has high effect of sterilizing and decomposing harmful gas pollutant.
In some embodiments of the present invention, referring to fig. 3 and 4, the fan assembly 30 includes two centrifugal fans (for example, a first centrifugal fan 31 and a second centrifugal fan 32) arranged side by side in the transverse direction and a front liner plate 34 connected to the front portions of the two centrifugal fans, wherein the front liner plate 34 and the volutes of the two centrifugal fans jointly define an air duct out of the fan assembly 30. 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 front liner plate 34 is arranged on one side, facing away from the heat exchange device 20, of the volute, and the front liner plate 34 and the volutes of the two centrifugal fans form an air channel of the fan assembly 30 together. The first centrifugal fan 31 and the second centrifugal fan 32 may be forward-direction centrifugal fans or backward-direction centrifugal fans.
Further, the front 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 ion wind generating device 40 from the natural air flowing from the second air inlet 122 to the heat exchanging device 20. Therefore, mutual interference of natural air flowing to the ion wind generating device 40 and the heat exchange device 20 can be avoided, phenomena such as turbulent flow, turbulent flow or mixed flow can be 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.

The design can also isolate the natural air flowing from the first air inlet 121 to the ion wind generating device 40 from the natural air flowing from the second air inlet 122 to the heat exchanging device 20.
In some embodiments of the present invention, the cabinet 10 includes a rear case 14, a front panel 13, and a first side air duct 151 and a second side air duct 152. The rear case 14 serves to constitute a rear portion of the cabinet 10. The front panel 13 is disposed at a front side of the rear case 14 to constitute a front portion of the cabinet 10. The first side air duct 151 and the second side air duct 152 are respectively located at two lateral ends between the rear casing 14 and the front panel 13, that is, the first side air duct 151 and the second side air duct 152 are both located in a space defined between the rear casing 14 and the front panel 13 and are respectively located at two lateral ends of the space. The outer ports of the first and second side air ducts 151 and 152 form the first and second lateral outlets 112 and 113, respectively.
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.
Fig. 5 is a schematic structural view of an air conditioning indoor unit according to an embodiment of the present invention after a front panel is hidden. Referring to fig. 3 to 5, the air duct of the fan assembly 30 has two lateral air duct outlets facing the lateral sides and a bottom air duct outlet facing the lower air outlet 111. The inner side ports of the first side air duct 151 and the second side air duct 152 are respectively connected to two lateral air duct outlets of the fan assembly 30, so as to form a sealed air duct completely separated and independent from the first air inlet 121 and the ion wind generating device 40 between the second air inlet 122, the heat exchanging device 20, the fan assembly 30, the first lateral air outlet 112, and the second lateral air outlet 113. That is, except for the lower air outlet 111, the air path driven by the fan assembly 30 and the air path driven by the ion wind generating device 40 are completely isolated from each other, and do not interfere with each other or affect each other, so as to avoid disturbance between air flows to affect the flow direction and the flow rate of the air flows.

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, the air-conditioning indoor unit 1 can be further ensured to form an encircling air supply effect, 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.
Further, the first air guiding channel 61 is cylindrical and extends along an 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 air guiding channel 62 and the first air guiding channel 61 are symmetrically arranged, that is, the second air guiding channel 62 is also tubular, and the cross section of the second air guiding channel extends along the same circular arc-shaped curve from inside to outside. The circle center of the circle of the circular arc curve is positioned at the front side of the circular arc curve, namely the circular arc curve has a shape which is convexly curved backwards. 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, the second lateral air outlet 113 and the lower air outlet 111 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.
Specifically, 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 side air duct outlets of the fan assembly 30 (for example, a volute outlet of the first centrifugal fan 31) to the first side air outlet 112, and the tubular body defines the first air guiding channel 61 therein. Similarly, the second side air duct 152 may be a tubular body that is bent and extended along the arc-shaped curve from the other side air duct outlet of the fan assembly 30 (for example, the volute outlet of the second centrifugal fan 32) to the second side air outlet 113, and the second air guiding channel 62 is defined in the tubular body.

In some embodiments of the present invention, referring to fig. 6, 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 three air outlets of the indoor air conditioner 1 can supply air towards the front of the transverse outer side of the casing 10 and the front of the lower part of the casing respectively 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 being directly blown 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 cross-sectional view taken along a sectional line a-a in fig. 6. In some embodiments of the present invention, referring to fig. 7, the fan assembly 30 and the ion wind generating device 40 each include a bottom air guiding channel for guiding air to flow toward the lower air outlet 111, and the bottom air guiding channel extends obliquely forward or curves from top to bottom to the lower air outlet 111. The inclination or curvature of the bottom air guiding channel 33 of the fan assembly 30 is greater than that of the bottom air guiding channel 44 of the ion wind generating device 40. Specifically, the bottom air guiding channel 33 may communicate with the rear half of the lower air outlet 111, and the bottom air guiding channel 44 may communicate with the front half of the lower air outlet 111. Therefore, the forward inclination degree of the heat exchange air blown out from the lower air outlet 111 and guided by the bottom air guide channel 33 of the fan assembly 30 is larger than the forward inclination degree of the natural air blown out from the lower air outlet 111 and guided by the bottom air guide channel 44 of the ion wind generating device 40, so that the cross mixing of the heat exchange air at the rear side and the natural air at the front side is facilitated, and the mixing effect of the two air is better.
Further, the inclination or curvature of the bottom air guiding channel 33 of the fan assembly 30 and the inclination or curvature of the bottom air guiding channel 44 of the ion wind generating device 40 are configured such that: the lower air outlet 111 is located below the horizontal plane where the air outlet is located and supplies air within the range of 0-85 degrees with the horizontal plane. Specifically, after being guided by the two bottom air guide channels, the lower air blowing opening 111 can blow air in the area between the broken line m and the broken line n in fig. 7, where the curved arrow between the broken line m and the broken line n is the approximate flow direction of the air flow. Therefore, when the air-conditioning indoor unit 1 heats, the lower air outlet 111 can blow down hot air which forms an angle of 85 degrees with the horizontal plane, thereby overcoming the technical problems that the hot air is easy to rise and is difficult to blow down.
In some embodiments of the present invention, referring to fig. 3 and 4, the heat exchanging device 20 may be a flat plate evaporator to improve heat exchanging efficiency, reduce the thickness of the indoor unit 1 in the front-rear direction, and thus reduce the volume of the indoor unit 1.
Further, a fixing bracket 80 for fixing the heat exchanging device 20 may be disposed between the rear housing 14 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.
Fig. 8 is a schematic structural view of a discharge module of the ion wind generating apparatus according to an embodiment of the present invention. In some embodiments of the present invention, referring to fig. 3, 4 and 8, the ion wind generating device 40 comprises at least one discharge module 410. Each discharge module 410 has a metal mesh 411 and a plurality of discharge needles 412 arranged in an array above the metal mesh 411. Specifically, the needle point of the discharge needle 412 is close to the metal mesh 411, positive and negative high voltage electrodes are respectively applied to the discharge needle 412 and the metal mesh 411, the discharge needle 412 corresponds to a radiation electrode for generating corona discharge, and the metal mesh 411 corresponds to a receiving electrode. The flow direction of the ion wind generated by each discharge module 410 is from top to bottom, 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. Referring to FIG. 9, areThe air blowing speed of the ion wind generating apparatus is increased, and a 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 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, the ion wind generating device 40 includes a plurality of discharge modules 410 arranged in sequence and connected in parallel or in series, and 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. Therefore, when the discharge needles 412 (corresponding to the emitters) are connected to the high-voltage positive electrode and the metal mesh 411 (corresponding to the receiver or the ground electrode) is grounded, corona discharge occurs between the discharge needle 412 and the corresponding metal mesh 411 in each discharge module 410, so that the ion wind can be accelerated multiple times through the plurality of discharge modules 410, and the superposition of the wind speed can be realized to obtain a high wind outlet speed. 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, each discharge module 410 further includes a housing 414 having at least four peripheral wall plates, and the housing 414 is hollowed out or provided with air inlet holes at the top to allow natural air to flow into the housing 414. 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 lower side of the metal conductive strip 413 facing the metal mesh 411. The lower surface of each metal conductive strip 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.
