Description
Technical Field
The invention relates to the air conditioning technology, in particular to an air conditioner indoor unit.
Background
At present, the air outlet mode of the traditional wall-mounted air conditioner indoor unit is mostly lower air outlet, and a guide plate is usually arranged at the air outlet of the traditional wall-mounted air conditioner indoor unit 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.
Some indoor units of air conditioners in the prior art are respectively provided with an air outlet at the lower part and the left and right ends thereof, and a fan is arranged in the casing corresponding to each air outlet. The lower part air outlet faces the lower part front side of the casing, and the air outlets at the left end and the right end face the left side and the right side of the casing respectively, so that the air supply effect in a large range is achieved through lower part air outlet and left end air outlet. However, the noise generated by the rotating part of the fan in the operation process is relatively large, so that the overall noise of the air conditioner indoor unit is relatively large, and the use trouble is brought to users. In addition, the air-conditioning indoor unit seems to have a relatively large air supply range, but the wall-mounted air-conditioning indoor unit is usually installed on a wall adjacent to a corner in a room, and air supplied through air outlets at the left end and the right end of the wall-mounted air-conditioning indoor unit is usually directly blown to another wall perpendicular to the wall where the indoor unit is located or blown out of the other wall, and the two areas do not belong to normal activity areas of users. 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 and 2, an air conditioning indoor unit 1 according to an embodiment of the present invention includes a casing, a heat exchanger 20, a main ion wind generator 33, a first side ion wind generator 31, and a second side ion wind generator 32.
The casing has at least one air inlet, a lower air outlet 111 at a lower portion of the casing, and a first lateral air outlet 112 and a second lateral air outlet 113 at both sides of the casing and facing a lateral front of the casing, respectively. Specifically, the air sent out through the first lateral air outlet 112 and the second lateral air outlet 113 is blown to the lateral front of the casing, the air sent out through the lower air outlet 111 is blown to the lower front of the casing, and the air sent out through each air outlet can directly reach the normal moving area of the user, so that the air supply effect of the left, right and lower surfaces can be achieved, the limitation on the installation position of the air-conditioning indoor unit 1 is weakened, the air supply angle of the air-conditioning indoor unit 1 is increased, and the air supply range of the air-conditioning indoor unit 1 is expanded.
The heat exchanging device 20 is disposed in the cabinet and configured to exchange heat with air flowing therethrough to change the temperature of the air flowing therethrough into cold air or hot air. Further, the heat exchanging device 20 may include a folded plate evaporator surrounding the main ion wind generating device 33, so that the wind flowing to the main ion wind generating device 33, the first side ion wind generating device 31 and the second side ion wind generating device 32 is the wind after heat exchange by the heat exchanging device 20. The folded plate type evaporator can comprise three sections of evaporators which are connected in a bent mode.
The main ion wind generating device 33 is disposed in a flow path from the heat exchanging device 20 to the lower outlet 111 in the housing, so as to force the air heat-exchanged by the heat exchanging device 20 to flow toward the lower outlet 111 by an electric field force. The first and second lateral ion wind generating devices 31 and 32 are respectively disposed on a flow path from the heat exchanging device 20 to the first and second lateral wind outlets 112 and 113 in the cabinet, so as to force the air heat-exchanged by the heat exchanging device 20 to flow toward the first and second lateral wind outlets 112 and 113, respectively, through an electric field force.
The main ion wind generating device 33, the first side ion wind generating device 31 and the second side ion wind generating device 32 all obtain kinetic energy from particles in the air by means of electric field force, thereby forming ion wind. Compared with a rotary air supply assembly (such as a fan), the ion air generating device has the advantages of pressure loss, low energy consumption, low noise and the like, so that the noise generated when the air conditioner indoor unit 1 operates is reduced. Meanwhile, since the ion wind generated by the main ion wind generating device 33, the first lateral ion wind generating device 31 and the second lateral ion wind generating device 32 is not generated by pressure, but is a soft wind close to nature generated by electric field force, the comfort level of the air-conditioning indoor unit 1 can be improved.
Specifically, the heat exchanging device 20 may be located upstream of the main ion wind generating device 33, the first side ion wind generating device 31 and the second side ion wind generating device 32 in the air flow direction inside the cabinet.

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, so that the air conditioner indoor unit can 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. Specifically, the first lateral ion wind generating device 31 and the first lateral wind outlet 112 are respectively located at two ends of the first wind guiding channel 61, and the second lateral ion wind generating device 32 and the second lateral wind outlet 113 are respectively located at two ends of the second wind guiding channel 62.
Referring to fig. 2 and 3, in some embodiments of the present invention, the first wind guiding channel 61 is a cylinder shape, and extends along a circular arc curve from inside to outside.

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.
In some embodiments of the present invention, an inner side edge 1121 of the first lateral air outlet 112, which is close to a vertical bisecting plane 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, so that the first lateral air outlet 112 faces the outer side front of the casing. 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 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-conditioning unit 1 can form an encircling air supply effect, so that the air supply range of the indoor air-conditioning unit 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-conditioning unit 1 is further improved, and the use experience of a user is better.
In some embodiments of the invention, the enclosure comprises: a rear case 14 for constituting a rear portion of the cabinet; a cover 16 covering the rear case 14; a front panel 13 provided at a front side of the cover 16 to constitute a front portion of the cabinet; and two side end caps 151 and 152 respectively located at both lateral ends of a pre-assembly member formed by assembling the front panel 13, the rear case 14, and the cover 16, for constituting both side portions of the cabinet. That is, two side end caps 151 and 152 are adjacent to both lateral sides of the cabinet, respectively. The main ion wind generating device 33 can be fixedly supported on the rear casing 14, so that the rear casing 14 can be used as a load-bearing framework of the whole air conditioning indoor unit 1. The rear casing 14 may be provided with a hanging hole for hanging the whole indoor unit 1 of the air conditioner on a wall.
Further, the first and second lateral outlets 112 and 113 are formed at front sides of the two side end caps 151 and 152, respectively. That is, the first side outlet 112 is opened in the front wall of the side cover 151, and the second side outlet 113 is opened in the front wall of the side cover 152. Specifically, the first and second lateral outlets 112, 113 may be substantially circular, oval, kidney-shaped, or other suitable shapes. Specifically, in the embodiment of the present invention, each of the first lateral air outlet 112 and the second lateral air outlet 113 has a substantially oval shape, and the major axis thereof extends in the vertical direction.
Further, the casing of the indoor unit 1 may have an air inlet 12, the air inlet 12 may be formed at the top of the cover 16, and a plurality of air-inducing grills are disposed at the air inlet 12. In other embodiments of the present invention, the casing of the indoor unit 1 may further have two or more air inlets, and other air inlets than the air inlet 12 may be disposed between the bottom of the rear casing 14 and the bottom of the front panel 13 of the casing, for example.
In some embodiments of the present invention, the first air guiding passage 61 and the second air guiding passage 62 are formed inside the two side end caps 151 and 152, respectively. Specifically, the side end cap 151 may be provided with a tubular body that is bent and extended along the arc-shaped curve from a position adjacent to the first lateral ion wind generating device 31 in the housing to the first lateral wind outlet 112, and the tubular body defines the first wind guiding channel 61 therein. Similarly, a tubular body extending from a position adjacent to the second lateral ion wind generating device 32 in the housing to the second lateral wind outlet 113 along the arc-shaped curve may be disposed inside the side end cap 152, and the second wind guiding channel 62 is defined in the tubular body.
In some embodiments of the present invention, the indoor unit 1 of the air conditioner further includes a first movable air guiding mechanism 51 disposed between the first side ion wind generating device 31 and the first side wind outlet 112, and a second movable air guiding mechanism 52 disposed between the second side ion wind generating device 32 and the second side wind outlet 113, so as to adjust wind outlet angles of the first side wind outlet 112 and the second side wind outlet 113, respectively. Specifically, the first movable air guiding mechanism 51 and the second movable air guiding mechanism 52 may be respectively disposed in a position adjacent to the first lateral ion wind generating device 31 in the first air guiding passage 61 and a position adjacent to the second lateral ion wind generating device 32 in the second air guiding passage 62. Thus, both the first movable air guiding mechanism 51 and the second movable air guiding mechanism 52 can be hidden inside the casing of the indoor unit 1 of the air conditioner. In the normal use process of the indoor air conditioner 1, a user cannot see the two movable air guide mechanisms, so that the indoor air conditioner 1 is attractive in appearance, and can shield noise generated by a motor driving the two movable air guide mechanisms to rotate and noise generated by the two movable air guide mechanisms when the two movable air guide mechanisms rotate to a certain extent, thereby reducing the noise generated when the indoor air conditioner 1 operates integrally.
Further, each of the first movable air guiding mechanism 51 and the second movable air guiding mechanism 52 has: the first movable air deflector extends along the vertical direction and is configured to controllably rotate back and forth around a rotating shaft extending vertically; and at least one second movable air deflector which is vertical to the first movable air deflector and is configured to be controlled to rotate up and down around a rotating shaft extending horizontally. Specifically, taking the first movable air guiding mechanism 51 as an example, it has a vertically disposed first movable air guiding plate 511 and two second movable air guiding plates 512. Each second movable air deflector 512 is perpendicular to the first movable air deflector 511. Each second movable air deflector 512 has a slot extending horizontally, and the first movable air deflector 511 is inserted into the slots of the two second movable air deflectors 512, so that two parts of each second movable air deflector 512 separated by the slot are respectively located at two sides of the first movable air deflector 511, thereby more evenly guiding the air flow passing through the second movable air deflector 512.
The first movable air guiding mechanism 51 can adjust the air outlet angle of the first side ion wind generating device 31 in the front-rear direction through the first movable air guiding plate 511, and can adjust the air outlet angle of the first side ion wind generating device 31 in the up-down direction through the second movable air guiding plate 512. That is, the first movable air guiding mechanism 51 can adjust the direction of the air flow in the first air guiding channel 61 in multiple directions, i.e., up, down, front, and back, so as to increase the adjustable angle range, thereby expanding the air supply range of the indoor unit 1 of the air conditioner.
Since the second movable air guiding mechanism 52 is disposed symmetrically to the first movable air guiding mechanism 51, it is not described herein again.
In some embodiments of the present invention, the air conditioning indoor unit further includes two fixing support members 71 and 72 respectively provided between both lateral ends of the rear case 14 and the two side end caps 151 and 152. That is, the fixed support member 71 is located between one of the lateral side ends of the rear housing 14 and the side end cap 151 for indirectly fixing the side end cap 151 to the rear housing 14 and for supporting the first lateral ion wind generating device 31. The fixed support member 72 is located between the other lateral side end of the rear housing 14 and the side end cap 152 for indirectly fixing the side end cap 152 to the rear housing 14 and for supporting the second lateral ion wind generating device 32. Further, a through hole is opened in the middle of each of the two fixed support members 71 and 72, so that the first and second lateral ion wind generating devices 31 and 32 are respectively fixed on the fixed support members 71 and 72 through the through holes, and thus the wind sent out by the first and second lateral ion wind generating devices 31 and 32 respectively flows to the first wind guiding channel 61 and the second wind guiding channel 62. The size of the through hole can be consistent with the external sizes of the two lateral ion wind generating devices and the sizes of the air inlets of the two air guide channels, which are positioned in the shell.
Specifically, the two fixing support members 71 and 72 and the rear case 14 may be fixed together by means of screwing or clipping. The fixing support member 71 and the side end cap 151, and the fixing support member 72 and the side end cap 152 may be fixedly connected together by means of screw connection or snap connection.
In some embodiments of the present invention, vertically extending partition plates 34 are disposed between the main ion wind generating device 33 and the first side ion wind generating device 31, and between the main ion wind generating device 33 and the second side ion wind generating device 32, so as to form three independent air supply ducts respectively communicating the main ion wind generating device 33 and the lower air outlet 111, the first side ion wind generating device 31 and the first side air outlet 112, and the second side ion wind generating device 32 and the second side air outlet 113 in the housing. Therefore, the air flows at the air inlets of the main ion wind generating device 33 and the two lateral ion wind generating devices can be prevented from interfering with each other, and the air outlet speed and the air outlet volume of the lower air outlet 111, the first lateral air outlet 112 and the second lateral air outlet 113 are improved. The first side ion wind generating device 31 and the second side ion wind generating device 32 are respectively arranged at two transverse sides of the main ion wind generating device 33, so that the thickness of the indoor unit 1 of the air conditioner in the front and back directions is reduced, the appearance effect of the indoor unit 1 of the air conditioner is optimized, and the requirement of a user on a small installation space of the indoor unit 1 of the air conditioner is met.
Specifically, two partition plates 34 may be respectively snap-fitted on the rear housing 14 and respectively located at both lateral ends of the main ion wind generating device 33.
Fig. 4 is another schematic cross-sectional view of an indoor unit of an air conditioner according to an embodiment of the present invention, referring to fig. 2 and 4, in some embodiments of the present invention, the primary ion wind generating device 33, the first ion wind generating device 31, and the second ion wind generating device 32 each include at least one pair of emitter and receiver electrodes disposed opposite to each other, wherein the emitter electrode has at least one electrode plate and a plurality of discharge needles disposed on the at least one electrode plate and directed toward the receiver electrode.
Further, the main ion wind generating device 33 includes a plurality of pairs of oppositely disposed emitting electrodes 331 and receiving electrodes 332 arranged at intervals to the lower air outlet 111 by the heat exchanging device 20, and the relative positions between the emitting electrodes 331 and the receiving electrodes 332 of each pair are the same. Specifically, the emitter 331 of each pair is located above the receiver 332 of the pair, so that the emitters 331 and the receivers 332 are spaced apart. Therefore, the amount of the ion wind generated by the main ion wind generating device 33 can be increased to a certain extent, and the indoor unit 1 of the air conditioner is ensured to have larger wind output and certain wind output speed.
In some embodiments of the present invention, the primary ion wind generating device 33 includes four pairs of oppositely disposed emitter 331 and receiver 332 poles. The emitter 331 of each pair has an electrode plate and a plurality of discharge needles disposed on the electrode plate and directed toward the receiver 332. In other embodiments of the present invention, the emitter 331 of each pair may further have two or more electrode plates, each of which is provided with a plurality of discharge needles.
Specifically, taking the first lateral ion wind generating device 31 as an example, fig. 5 is a schematic structural view of the first lateral ion wind generating device according to an embodiment of the present invention. Referring to fig. 2 and 5, the first lateral ion wind generating device 31 includes an emitter 311 and a receiver 312, the emitter 311 having an electrode plate 3111 and a plurality of discharge needles 3112 disposed on the electrode plate 3111 and directed toward the receiver 312. The receiver electrode 312 is substantially a porous network structure, such as a network structure having circular holes, a network structure having square holes, or a network structure having diamond holes. The radiating tips of the plurality of discharge needles 3112 of the discharge electrode 311 can be inserted into and adjacent to the plurality of holes of the receiving electrode 312 to form a high voltage corona field in the holes, increasing the discharge amount, thereby increasing the wind speed and the wind amount of the ion wind generated by the first lateral ion wind generating device 31.
When a certain voltage is applied between the emitter 311 and the receiver 312, corona discharge is generated at the tips of the plurality of discharge needles 3112 of the emitter 311, and gas around the discharge needles 3112 is ionized to form hundreds of millions of ions, which bind to and electrically charge gas molecules or dust particles in the air. Charged gas molecules or dust particles are quickly attracted by the receiving electrode under the action of the high-voltage electric field, so that ion wind is formed.
In another embodiment of the present invention, the first lateral ion wind generating device 31 may further include two or more electrode plates 3111 arranged side by side, and each electrode plate 3111 is provided with a plurality of discharge needles 3112 to increase the amount of ion wind generated by the first lateral ion wind generating device 31, thereby increasing the wind output of the first lateral wind outlet 112.
Since the second lateral ion wind generating device 32 has the same structure as the first lateral ion wind generating device 31, it will not be described in detail here.
