Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings.

The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit of the air conditioner.

For the sake of description, the air conditioning indoor unit 100 is defined such that the rear panel 15 side is the rear side and the front panel 14 side is the front side.

The air conditioning indoor unit 100 may be an on-hook mounted to a wall with the rear panel 15 against the wall, however, embodiments of the present disclosure are not limited thereto.

The upper panel 17 includes an upper panel body 171, a plurality of air inlet guide portions 172 are disposed in the middle of the upper panel body 171, the length of the air inlet guide portions 172 extends in the left-right direction, the air inlet guide portions 172 are arranged in parallel at intervals along the front-back direction of the upper panel 17, and the air inlets 11 are formed at intervals between the air inlet guide portions 172.

With continued reference to FIG. 3, the heat exchanger 2 is disposed between the fan 31 and the intake vent 11 and is disposed in the air flow path of the intake vent 11 and the exhaust vent 12 for absorbing heat from or transferring heat to air flowing in through the intake vent 11.

A drain pipe extending to the outside of the case 1 may be connected to the water collector 8 to discharge the condensed water to the outside of the case 1. A spaced path 72 is provided between the front outer surface of the drip tray 8 and the front panel 14 and the rear surface of the drip tray 8 is provided for collecting water condensed in the heat exchanger 2.

A plurality of micropores 91 are distributed on the front panel 14 and the air deflector 4, and the size of the micropores 91 is far smaller than that of the air outlet 12.

The air outlet path 71 forms a soft air outlet path when communicating with the spacing path 72, and the air outlet path 71 forms a strong air outlet path when communicating with the air outlet 12 when the air deflector 4 rotates to open the air outlet 12. That is, when the air deflector 4 is opened, the air in the air outlet path 71 can send out a strong heat exchange airflow from the air outlet 12; when the air deflector 4 is closed, the air in the air outlet path 71 can send out a weak heat exchange airflow from the micro-hole 91 along the soft air outlet path.

For example, during a cooling operation, the air conditioner indoor unit 100 may open the air deflector 4 first, send out strong cold air into the room through the air outlet 12, reduce the temperature in the room as soon as possible, close the air deflector 4 after the room temperature meets a requirement, and send out soft cold air into the room through the micro holes 91, so that the temperature in the room is kept in a stable state, and the soft air does not cause a problem of blowing people, thereby greatly improving the use experience of a user.

An avoiding part 81 is arranged on the water receiving tray 8, and the avoiding part 81 can reserve a rotating space for the upper end of the air deflector 4.

The micro holes 91 are distributed on the air deflector 4 and the front panel 14, and the air supply range of the soft wind can be expanded, and it can be understood that the micro holes 91 are arranged on the parts of the air deflector 4 and the front panel 14, and the soft wind can be sent out only within a set angle.

The housing 1 may further comprise a front frame 13, the front frame 13 being attached to the upper front side of the drip tray 8, and the front frame 13 being located within a front panel 14, the front panel 14 being removably attached to the front frame 13, for example in the form of a snap-fit.

The gap between the front surface of the front frame 13 and the front panel 14 serves as a part of the spacing path 72 and extends the spacing path 72.

In the embodiment of the present disclosure, the heat exchanger 2 and the partition path 72 need a partition to separate, and the water pan 8 and the front frame 13 serve as a partition, the partition path 72 gradually narrows from bottom to top, and the minimum distance from the front surface of the water pan 8 and the front frame 13 to the front panel 14 is not less than 2mm, that is, the minimum width of the partition path 72 is not less than 2mm, so that when air is discharged from the micro-holes 91 of the front panel 14, too much condensation is generated on the inner wall of the front panel 14 due to the narrow air outlet space.

As shown in fig. 3, the front panel 14 and the upper panel 17 are curved panels, both of which have a small arc, the arc of the front panel 14 can enlarge the air outlet area of the micro-holes 91, the micro-holes 91 can radiate a larger air supply area, the arc of the upper panel 17 can enlarge the air inlet area, and the air inlet 11 can radiate a larger air inlet area, so that the air inlet area and the air supply area are maximized in the indoor unit with the same volume, the heat exchange efficiency of the indoor unit 100 of the air conditioner is improved, the temperature in the room can reach the set value as soon as possible in strong wind, the maximum air supply area is covered in soft wind, and the time for maintaining the temperature in the room is as long as possible.

Specifically, the curvature P1 of the upper panel 17 and the curvature P2 of the front panel 14 satisfy: p1 is more than or equal to 0.002 and less than or equal to 0.014; 0.002 is less than or equal to P2 is less than or equal to 0.014, wherein P1 and P2 can be the same or different; if the curvature is too large, the space inside the shell 1 can be reduced, the arrangement of the heat exchanger 2 and the fan 3 and the flow design of the air channel are influenced, the refrigerating and heating effects can be influenced from the air conditioning performance, and if the curvature is too small, the effect of increasing the air inlet and outlet area cannot be achieved.

On the projection of the side panel 16 of the indoor unit 100 of the air conditioner, the included angle α between the connecting line of the two ends of the upper panel 17 and the connecting line of the two ends of the front panel 14 satisfies: alpha is more than 50 degrees and less than 85 degrees, and the included angle beta between the air deflector 4 and the wall pasted by the rear panel 15 when the air deflector is opened to the maximum state meets the following requirements: beta is more than 60 degrees and less than 90 degrees; too large values of alpha and beta can bring the risk of short circuit of air flow and influence the heat exchange effect of the air conditioner, and too small values of alpha and beta can make the air supply angle biased to the rear wall and also influence the indoor heating efficiency; therefore, the arrangement of the alpha and the beta can realize better air inlet angle and air supply angle so as to achieve better heat exchange effect.

The matching arrangement of the P1, P2, alpha and beta values realizes the maximum inlet and outlet area, and also gives consideration to the proper inlet and outlet wind angle, and the structure of the air conditioner is more compact.

More specifically, when P1 is more than or equal to 0.005 and less than or equal to 0.008, P2 is more than or equal to 0.005 and less than or equal to 0.008 and alpha is more than or equal to 65 and less than or equal to 75 degrees, the internal structure and the air inlet and outlet angle of the air conditioner are most reasonable.

With continued reference to fig. 3, in the upper panel 17, the vertical center line of the air intake guide portion 172 is parallel to the wall on which the rear panel 15 is hung, and does not follow the radian of the upper panel 17 to change obliquely, and because the air state near the wall is the most stable, with this structure, the air intake 11 can draw air from the area near the wall as much as possible, and as much as possible, the air intake is prevented from being affected by the turbulence of the air discharged from the front panel 14, thereby ensuring the effectiveness of the air intake and the possibility of the maximum air volume.

The air intake guide portions 172 are connected by a connecting rod 173 to reinforce the overall strength of the upper panel 17. The upper end of the connecting rod 173 is lower than the upper surface of the air inlet guide 172, so that the influence of the connecting rod 173 on the air inlet angle is reduced as much as possible. A grid-shaped air inlet grille is formed between the air inlet guide part 172 and the connecting rod 173.

The upper end of the air inlet guide part 172 is higher than the upper surface of the upper plate body 171, so that the air guiding range can be extended, and the cleaning and maintenance operation of the air inlet guide part 172 is facilitated. The upper surface of the air intake guide 172 has the same curvature of curvature as the upper panel 17.

Still be provided with a plurality of blind holes 92 on the front panel 14, blind hole 92 can regard as the mould thimble position when the front panel shaping, blind hole 92 distributes sporadically between micropore 91, for the convenience of description, it includes micropore 91 and blind hole 92 to define hole 9, hole 9 arranges according to setting for regular row on the front panel, interval between adjacent hole 9 is roughly equal, and blind hole 92 is more dispersed, the relative micropore 91 of quantity is also less, influence to the exhaust air can be ignored, utilize this kind of structure, can guarantee that the air conditioner discharges the gentle breeze uniformly, the neat unanimous outward appearance effect of front panel 14 has been ensured simultaneously.

Specifically, the area S1 of the air outlet 12 is substantially 1/4-1/2 of the area of the front panel 14, the total area of the micropores 91 on the front panel 14 is S2, and S1/S2 is more than 0.5 and less than 10. With this structure, when the air deflection plate 4 opens the outlet 12, air can be easily blown to the outlet 12, not to the minute holes 91. The area S of the minute hole 91 may be set to 0.03mm²≤S≤3mm²And the dispersion softness of the outlet air is ensured.

Similarly, the air deflector 4 can also be provided with the blind holes 92 and the micro-holes 91, so that the appearances of the air deflector 4 and the front panel 14 are neat and consistent, the arrangement of the holes 9 on the air deflector 4 is the same as the arrangement of the holes 9 on the front panel 14, when the front panel 14 is in a closed state, the holes 9 on the air deflector 4 and the holes 9 on the front panel 14 are distributed according to a uniform and regular arrangement, and the uniformity and symmetry of the soft air outlet at any position are ensured.

The axes of the micro-holes 91 are parallel and do not change along with the radian of the panel, so that the same air outlet direction of the micro-holes 91 can be realized.

As an example, as shown in fig. 5 and fig. 6, the air deflector 4 is located at a position above and below the front panel 14, the area of the micro-hole 91 in the region above the air deflector 14 on the front panel 14 is larger, and the area of the micro-hole 91 in the other region on the front panel 14 is smaller, so that the air outlet region of the air conditioner located in the middle part can be fully utilized.

The shape of the micro holes 91 is not limited, and may be circular holes or waist-shaped holes, or specific patterns may be designed by the arrangement of the micro holes 91 to increase the appearance of the air conditioner.

In some embodiments of the present disclosure, as shown in fig. 5 and fig. 6, the air deflector 4 is closed only in the mode of blowing air through the micro holes 91 on the front panel 14 and the air deflector 4, and there is a large possibility of forming condensation even when the air deflector 4 is completely closed, so in the present air conditioning indoor unit 100, when the air deflector 4 is completely closed, a gap Δ not less than 1mm is formed between the peripheral portion of the air deflector 4 and the front panel 14, and the probability of generating condensation at the air deflector 4 in the soft air blowing mode can be reduced.

The gap delta has the same width in the longitudinal direction and the transverse direction, so that the consistency of the appearance of the air conditioner and the uniformity of air outlet can be ensured when the air deflector 4 is closed.

The width of the gap delta can be smaller than five times of the vertical width of the micropores, so that more strong wind can be prevented from flowing out when the gap delta is too wide in the soft wind mode of the air conditioner.

Fig. 7 illustrates a perspective view of an air conditioning indoor unit according to an embodiment of the present disclosure.

the relationship between the area S1 of the outlet 12 and the total area S2 of the micro holes 91 on the front panel 14 is: 0.5 < S1/S2 < 10; the sum of the areas of all micro-holes 91 in side panel 16, S3, and the sum of the areas of micro-holes 91 in front panel 14, S2, are related: S3/S2 is more than or equal to 0.25 and less than or equal to 2; by using the structure, the effects of soft wind output from the panel, strong wind output from the wind outlet 12 and shunt wind output from the side wall are preferably considered.

Because the side panel 16 is far away from the air outlet path 71, the air flow in the air outlet path 71 flows to the side panel 16 and loses much air flow, so that the micropores 91 on the side panel 16 can be arranged smaller than the micropores 91 on the front panel 16, the air supply range can be expanded through the micropores 91 on the side panel 16, most of the air flow can be discharged from the front panel 14 and the air guide plate 16, and the loss of heat exchange air flow is reduced.

In addition, the micro-holes 91 can be arranged on only a partial area of the side panel 16 close to the front panel 14, so that the loss of the air flow continuing to flow to the rear side of the side panel 16 is avoided.

The distances among the micropores 91 on the side panel 16, the front panel 14 and the air deflector 4 are the same, so that the consistency of appearance and the uniformity of air exhaust are ensured.

The insertion pieces 102 may have one or more, a plurality of insertion pieces 102 are distributed at intervals along the length direction of the sealing strip 10, and the plurality of insertion pieces 102 are inserted between the fins, so that the positional stability of the sealing strip 10 and the heat exchanger 2 can be ensured.

The fixing of the up-and-down direction position of the sealing strip 10 is realized by means of the hook 103 hanging on the refrigerant pipe 23 at the end part of the heat exchanger 2, specifically, the end part of the sealing strip 10 is formed with the hook 103, when the sealing strip 10 is placed at the top end of the heat exchanger 2, the hook 103 can be hung on the refrigerant pipe 23, and therefore the sealing strip 10 can be prevented from moving up and down.

One or more hooks 103 may be provided, and a plurality of hooks 103 may be respectively hung on the front section heat exchanger 21 and the rear section heat exchanger 22 to ensure the positional stability of the sealing strip 10 and the heat exchanger 2.

The hook 103 includes a connection portion 1031 and a hanging portion 1032, wherein the connection portion 1031 is connected to the sealing strip 10, the hanging portion 1032 may have one or more, if there are more, the hanging portions 1032 are connected to the connection portion 1031 at intervals, that is, the connection portion 1031 extends outward to form a plurality of hanging portions 1032, the hanging portions 1032 may be hung on different refrigerant pipes 23, and the reliability and stability of the hanging are increased. The front hook 103 has two hooking portions 1032 in this embodiment, and the rear hook 103 has one hooking portion 1032.

The hook 103, the inserting piece 102 and the sealing strip 10 are integrally formed through injection molding, and the production and processing efficiency is improved.
