FIG. 1 is a schematic front view of the vertical air conditioner indoor unit according to an embodiment of the present invention; FIG. 2 is the vertical air conditioner indoor unit in FIG. Schematic diagram when the air outlet 110 is opened; FIG. 3 is an enlarged view of part A of FIG. 2 .

As shown in FIGS. 1 to 3 , the vertical air conditioner indoor unit according to the embodiment of the present invention includes a casing 100 , an air outlet 110 , air outlet microholes 150 and an air guiding device. Wherein, the air outlet 110 is opened on the front side of the casing 100 , and the cold or hot air in the casing 100 is blown out of the casing 100 through the air outlet 110 . A plurality of air outlet microholes 150 are opened on the casing 100 and distributed outside the periphery of the air outlet 110 , and are also used to allow cold or hot air in the casing 100 to blow out of the casing 100 through the air outlet 110 . The air guiding device is arranged at the air outlet 110. When the vertical air conditioner indoor unit is running, the air guiding device is used to open and close the air outlet 110, and can also guide the direction of the air outlet 110.

In the embodiment of the present invention, the indoor unit of the vertical air conditioner is provided with a plurality of air outlet microholes 150 outside the periphery of the air outlet 110. After the air outlet 110 is completely closed by the air guiding device, the wind can still be sent out from the air outlet microholes 150. Enhanced the diversity of air supply modes. Because the caliber of the air outlet microhole 150 is small (specifically, the air outlet microhole 150 can be a round hole, and its aperture can be less than 5mm), the wind speed is small, and the indoor unit of the vertical air conditioner can achieve a similar airless cooling effect. Effect. The opening of multiple air outlet microholes 150 is also equivalent to increasing the total air outlet area of the casing 100 and improving the air supply effect.

In some embodiments, the air outlet 110 can be opened in a circular area on the surface of the casing 100, and a plurality of air outlet microholes 150 are distributed (preferably evenly distributed) between the outer contour 130 and the outer contour of the circular area. In the area between the periphery of the air outlet 110 . In this way, the entire air supply area of the casing 100 can present a circular appearance, with novel structure and beautiful appearance. Preferably, the air outlet 110 can also be made in a square shape.

In some embodiments, the center of the air outlet 110 may coincide with the center of the circular area. It is also possible to further make the four corners of the air outlet 110 on the outer contour of the circular area (refer to FIG. 1 ), and arrange a plurality of air outlet microholes 150 evenly on the four sides of the air outlet 110 outside, so that the appearance is more beautiful, and the air supply more uniform.

In some other embodiments, the air outlet 110 can also be replaced by other regular shapes from a square shape, and the distribution area of the air outlet microholes 150 can be replaced by other shapes from the above-mentioned circle, so that the surface of the casing 100 presents a more unique appearance. Appearance.

In some embodiments, the air guiding device includes a plurality of outer swing leaves 200, which are arranged parallel to each other at the air outlet 110, and the two ends of each outer swing leaf 200 are hinged to the casing 100, so that the plurality of outer swing leaves The layer swing blades 200 can open and close the air outlet 110 or guide the air outlet direction of the air outlet 110 synchronously. As shown in FIG. 1 and FIG. 2 , a plurality of outer swing vanes 200 may extend in the horizontal direction, and the state when the air outlet 110 is closed by the outer swing vanes 200 is shown in FIG. 1 . When the plurality of outer swing blades 200 swing synchronously at an angle to the state shown in FIG. 2 , the wind inside the casing 100 will be guided to blow out downward. A plurality of horizontally extending outer layer swing blades 200 can adjust the air output from the air outlet 110 in the up and down direction, and guide the air to blow upward, front upper, front, front lower and lower. Specifically, a linkage rod can be used to connect the plurality of outer swing leaves 200 to realize synchronous rotation, and the specific structure will not be repeated here. Further, a plurality of inner swing leaves can also be arranged at the air outlet 110 , both ends of the inner swing leaves are also hinged to the casing 100 , and the extending direction of the inner swing leaves is perpendicular to the outer swing leaves 200 . For example, the outer swing blade 200 is extended horizontally, and the inner swing blade is vertically extended. The inner swing blade can adjust the air outlet of the air outlet 110 along the left and right directions, and cooperates with the outer swing blade 200 to expand the air supply angle.

In the embodiment of the present invention, the air outlet 110 is set to a regular shape (such as a square), and the distribution area of the air outlet microhole 150 is designed to be a circle (or other irregular shape), for the convenience of designing the outer swing blade 200 , to realize the connection and sealing between the outer swing leaf 200 and the edge of the air outlet 110 . Those skilled in the art should be able to understand that if the air outlet is directly designed as a circular shape, in order to make the outer swing leaf swing smoothly, its edge will be far away from the edge of the air outlet, making it difficult to achieve sealing.

In some embodiments, as shown in FIG. 1 and FIG. 2 , only one aforementioned air outlet 110 may be provided on the front side of the casing 100 , and a plurality of air outlet microholes 150 may be provided outside the periphery of the air outlet 110 . In some other embodiments, in order to enhance the air supply volume, a plurality of (such as two arranged up and down) air outlets 110 can also be set on the front side of the casing 100, and a plurality of air outlets 110 can be arranged outside the periphery of each air outlet 110. Micropore 150.

Fig. 4 is a schematic diagram of the internal structure of a vertical air conditioner indoor unit according to an embodiment of the present invention. As shown in Figure 4, in one embodiment of the present invention, the vertical air conditioner indoor unit also includes an air inlet 120 opened on the rear side of the casing 100, a heat exchange device 300 located in the casing 100, an axial flow fan 500 and ion Wind generating device 400 . Wherein, the heat exchange device 300 is configured to perform heat exchange with the airflow entering the casing 100 through the air inlet 120 . The axial flow fan 500 is configured to force the airflow in the casing 100 to flow toward the air outlet 110 and the plurality of air outlet micro-holes 150 in a controlled manner. The ion wind generating device 400 is configured to make the airflow in the housing 100 flow toward the air outlet 110 and the plurality of air outlet micro-holes 150 by using the force of the electric field in a controlled manner. Specifically, the heat exchange device 300 may be an evaporator.

The ion wind generating device 400 can drive the air flow through the electric field force (the principle of the ion wind flow generated by the ion wind generating device 400 is relatively well known and easily obtained by those skilled in the art, so it will not be repeated here), the axial flow fan 500 The ion wind generating device 400 can be arranged in parallel or in series to blow cold air or hot air out of the casing 100 individually or jointly. The ion wind generating device 400 makes the particles in the air obtain kinetic energy by electric field force, thereby forming ion wind. Compared with rotating air supply components (such as fans), it has the advantages of small pressure loss, low energy consumption, and low noise.

Specifically, in some embodiments, as shown in FIG. 4 , the ion wind generator 400 is arranged in front of the axial flow fan 500 , and the axial flow fan 500 is arranged in front of the heat exchange device 300 , forming a series arrangement.

In other embodiments not shown in the drawings, the axial flow fan 500 and the ion wind generator 400 are arranged in parallel on the air flow path from the air inlet 120 to the air outlet 110 in the casing 100 . It should be noted that "connected in parallel" in the present invention means that the airflow sent by one of the above-mentioned axial flow fan 500 and the ion wind generator 400 will not pass through the other. Specifically, the axial flow fan 500 and the ion wind generator 400 may be arranged perpendicular to the flow direction of the airflow in the casing 100 . In this way, the uniform air outlet on the line and surface can be realized, and the problem of excessive wind speed in some areas and too small wind speed in some areas can be avoided, thereby expanding the air supply range and air volume of the indoor unit of the vertical air conditioner, and making the vertical air conditioner The airflow sent by the indoor unit is more balanced.

In some embodiments, the axial flow fan 500 and the ion wind generating device 400 are configured to be controlled to start one of them or to start them at the same time, so that the indoor unit of the vertical air conditioner works at a speed that is only driven by the axial flow fan 500. The cooling/speed heating mode or the silent mode in which the air supply is only driven by the ion wind generator 400 or the large air volume mode in which the axial flow fan 500 and the ion wind generator 400 simultaneously drive the air supply. That is to say, by controlling the start and stop of the axial flow fan 500 and the ion wind generator 400, the present invention can make the indoor unit of the vertical air conditioner have at least three working modes: fast cooling/heating, silent and large air volume, thereby simultaneously It satisfies various usage requirements of different users or the same user in different situations, and improves user experience.

Specifically, in the fast cooling/speed heating mode, the ion wind generator 400 does not start to operate, and the vertical air conditioner indoor unit only drives the air supply to the above-mentioned air outlet 110 and the air outlet microhole 150 through the axial flow fan 500, and the driven The airflow flows through the air passage in the ion wind generating device 400, and the ion wind generating device 400 does not produce any driving effect on the air flow. Since the axial flow fan 500 has relatively large air supply volume and relatively high cooling efficiency or heating efficiency, the indoor temperature can be quickly relieved. This mode is suitable for the situation where the indoor unit of the vertical air conditioner just starts to run, or other situations that require rapid cooling or heating. In silent mode, the axial flow fan 500 does not start to operate, and the indoor unit of the vertical air conditioner only drives the air supply to the air outlet 110 and the air outlet microhole 150 through the ion wind generator 400, and the driven airflow flows through the axial flow fan 500, The axial flow fan 500 does not produce any driving effect on the airflow. Since the operating noise of the ion wind generator 400 is close to or even lower than the indoor background noise, the overall noise of the indoor unit of the vertical air conditioner is greatly reduced, and the industry problem of ultra-low quiet air supply is solved. This mode is suitable for use environments such as medical care and child care, as well as situations where the vertical air conditioner indoor unit has been running for a period of time. In the large air volume mode, the axial flow fan 500 and the ion wind generating device 400 can be controlled and started to operate at the same time, so as to supply air to the air outlet 110 and the air outlet microhole 150 at the same time, that is, the air flow passes through the axial flow fan 500 and the ion wind. It is sent out after multiple actuation actions of the generating device 400. Therefore, this mode is suitable for situations with higher requirements on air volume and speed, faster cooling or faster heating, and other situations with higher requirements on wind speed.

Fig. 5 is a schematic exploded view of a discharge module of the ion wind generator 400 according to an embodiment of the present invention. In some embodiments of the present invention, referring to FIG. 5 , the ion wind generator 400 includes 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 behind the metal mesh 411 . The metal mesh 411 extends in a plane perpendicular to the front-rear direction. Circular holes, square holes, rhombus holes or through holes of other shapes are evenly distributed on the metal mesh 411 . The discharge needle 412 has a discharge tip, and the discharge tip can go straight to the center of a through hole of 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 is equivalent to the emitter electrode for generating corona discharge, and the metal mesh 411 is equivalent to the receiver electrode.

That is to say, the flow direction of the ion wind generated by each discharge module 410 is from the back to the front, 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. 6 is a schematic cross-sectional view of a discharge module according to an embodiment of the present invention. Referring to Fig. 6, in order to improve the air supply speed of the ion wind generating device 400, the designer of the present invention has carried out a large amount of wind speed measurement experiments, and the experimental results have found that the distance L between the needle tip of each discharge needle 412 and the metal mesh 411 is set to Make it satisfy L=aL ₁ (wherein, a is any constant between 0.7～1.3 in the scope, namely a can take the value of 0.7, 0.8, 0.9, 1.0, 1.1, 1.2 or 1.3, L ₁ is to make the metal mesh The distance between the tip of the discharge needle 412 and the metal mesh 411 when the ion wind velocity at the wind speed center point of 411 reaches the maximum wind speed _Vmax , the wind speed center point of the metal mesh 411 is the projection of the needle point of the discharge needle 412 on the metal mesh 411 point), on the one hand, the ion wind speed generated by the ion wind generator 400 can better meet the normal use needs of users; The areas can be partially overlapped 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 improve the air supply volume of the ion wind generating device 400, the designer of the present invention has carried out a large number of experiments on the measurement of the projection radius of the needle point, and the experimental results have found that the distance R between the needle points of two adjacent discharge needles 412 is set to make It satisfies R=aR ₁ (wherein, R ₁ is the distance between the wind speed measurement point and the wind speed center point where the wind speed reaches b times of the maximum wind speed _Vmax , and b is any constant between 0.3～0.7 in the range, i.e. b The possible values are 0.3, 0.4, 0.5, 0.6 or 0.7, and the value of a is the same as above), the ionized wind volume generated by the ionized wind generator 400 can better meet the normal use needs of users. At the same time, after the distance between two adjacent discharge needles 412 is specially designed, it can not only avoid the wind speed offsetting each other between two adjacent discharge needles 412 because the distance is too close, but also avoid the gap between the two discharge needles 412. If the distance between them is too far, the air volume will be reduced and the air volume distribution will be uneven.

It can be seen that the present invention can make the ion wind generating device 400 generate a uniform and comparatively high temperature by rationally designing the spatial positional relationship between the discharge needle 412 and the metal mesh 411, and at the same time rationally arranging the positional relationship between a plurality of discharge needles 412. The ion wind with a large air volume improves the air supply speed, air supply volume and air supply efficiency of the ion wind generating device 400 .

In some embodiments of the present invention, the ion wind generating device 400 includes a plurality of discharge modules 410 arranged in sequence along the front-to-back direction and connected in parallel or in series, each discharge module 410 has An extended metal mesh 411 and a plurality of discharge needles 412 located behind the metal mesh 411 and arranged in an array. Thus, a corona discharge phenomenon will be 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 multiple times through multiple discharge modules 410, and the wind speed can be adjusted. Superimposed to obtain higher wind speed. And under the action of high-speed air outlet, negative pressure can be formed to further increase the air intake, and improve the air supply speed, air supply volume and air supply efficiency of the multi-stage ion air supply module.

In some embodiments of the present invention, the discharge needles 412 of two adjacent discharge modules 410 are arranged directly opposite each other, that is to say, the discharge needles 412 of every two adjacent discharge modules are located at the outlet of the ion wind generator 400 The projections within the plane coincide. Thus, the area corresponding to the tip of each discharge needle 412 will generate a larger and stronger electric field, so this area will generate an ion wind with a higher local wind speed, and the ion wind blowing on the user will make the user have a strong sense of wind. In other words, this arrangement can obtain a local higher wind speed near each wind speed center point of the metal mesh 411, so as to improve the wind feeling when the indoor unit of the vertical air conditioner is driven by the ion wind generator 400 to blow air.

In some alternative implementations of the present invention, the discharge needles 412 of two adjacent discharge modules 410 are arranged in a staggered position. The embodiment shown in FIG. 7 is one of the dislocation arrangements, wherein the OZ axis represents the height direction, and the OY axis represents the lateral direction. For ease of understanding, the structures of two adjacent discharge modules 410 are shown in solid lines and dashed lines, respectively. The dislocation arrangement is: the discharge needles 412 of every two adjacent discharge modules are arranged in a lateral displacement, and the corresponding discharge needles 412 of every two adjacent discharge modules are within the air outlet surface of the ion wind generating device 400. The projections are on the same horizontal line (that is, the discharge needles 412 of every two adjacent discharge modules are arranged in a staggered position, but the corresponding discharge needles 412 are located at the same height). As a result, a relatively uniform soft wind can be generated in several linear regions in the horizontal direction, and the superposition of multiple discharge modules can form a larger and stronger electric field in this linear region, so the ions in this linear region The wind speed is relatively high. Furthermore, 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 form an isosceles triangle, so as to ensure that the ion wind generated by the ion wind generator 400 is evenly distributed.

The embodiment shown in FIG. 8 is another dislocation arrangement, wherein the OZ axis represents the height direction, and the OY axis represents the lateral direction. For ease of understanding, the structures of two adjacent discharge modules 410 are shown in solid lines and dashed lines, respectively. The other dislocation arrangement is: the discharge needles 412 of every two adjacent discharge modules are arranged in a dislocation in both the horizontal and vertical directions. Thus, the ionized wind generated by the ionized wind generator 400 can be uniformly distributed in its air outlet surface, so as to realize soft, uniform and large-volume air supply under the condition of low voltage, low electric field strength and low power. That is to say, the discharge needles 412 of every two adjacent discharge modules 410 are offset from each other, which can fill the gap between the plurality of discharge needles 412 of each discharge module 410 . As a result, a relatively uniform ion wind can be formed in the entire area of the metal mesh 411, and the overall air supply volume can be improved. Further, the discharge needles 412 of a plurality of discharge modules form an equilateral triangle in each group of three adjacent discharge needle projections formed in the wind outlet surface of the ion wind generating device 400, so as to ensure that the ion wind generating device 400 The resulting ion wind is more evenly distributed.

In some embodiments of the present invention, referring to FIG. 5 , each discharge module 410 further includes a housing 416, a metal conductive strip 413 having a plurality of metal conductive strips 414, and a metal conductive strip 413 electrically connected to the metal conductive strip 413 and perpendicular to the metal conductive strip 413. At least one PCB multilayer board 415 of the conductive strip 413 . The PCB multilayer board 415 has two layers of insulating protection layers, front and rear, and a conductive layer located between the two layers of insulating protection layers. The conductive layer is electrically connected to the metal conductive sheet 414 . A buckle 4161 is provided on the bottom wall of the housing 416 , and the metal conductive piece 414 of the metal conductive strip 413 is buckled into the buckle 4161 of the housing 416 .

The number of PCB multilayer boards 415 can be one, and it is roughly rectangular; .

A plurality of discharge needles 412 are evenly distributed on the outer side of at least one PCB multilayer board 415 facing the metal mesh 411 . Specifically, several pinholes for installing discharge needles 412 are opened on the outer surface of each PCB multilayer board 415 . The diameter of the pinhole is slightly smaller than the diameter of the discharge needle 412 so that the pinhole and the discharge needle 412 have an interference fit. A filling layer filled by a welding process is provided around the pinhole where the discharge needle 412 is inserted, that is, a filling layer filled by a welding process is provided around the discharge needle 412 of the pinhole to ensure that the discharge needle 412 and the PCB multilayer board The conductive layer in 415 maintains good electrical connection, and at the same time, it can strictly prevent the conductive layer from being exposed to the outside, so as to avoid random discharge or sparking.
