In this way, the air flow of the active heat exchange of the blower 14 is reduced while the overall cooling capacity is satisfied, thereby reducing the load of the blower 14, i.e., reducing the operating noise of the blower 14 while ensuring the cooling capacity. Meanwhile, the first cavity 102 is arranged in the middle of the two second cavities 104, and the fan 14 is arranged in the first cavity 102, so that the fan 14 can supply air to two sides at the same time, the air supply range of the air conditioner indoor unit 1 is ensured, the running path of air is reduced, the wind intensity of each position of the air conditioner indoor unit 1 is ensured, the installation space is reasonably utilized, and the arrangement rationality of the air conditioner indoor unit 1 is improved.

The heat exchange is carried out for indoor air in a natural convection mode, the whole heat exchange process does not need the fan 14 to work, and noise generated by the operation of the fan 14 is avoided under the condition of ensuring good heat exchange capacity.
In the strong wind mode, the fan 14 is turned on, and part of the airflow enters the housing 10 from the air inlet 106, enters the second cavity 104 through the jet nozzle 16, and is discharged from the air outlet 108. In this process, due to the driving of the fan 14, the air is sprayed into the second cavity 104 by the jet nozzle 16, so that the flow speed of the air in the second cavity 104 is increased, the air outlet volume of the air conditioner indoor unit 1 is increased, further the negative pressure effect in the second cavity 104 is enhanced, the air inlet volume and the air outlet volume of the second cavity 104 in the natural convection process are increased, that is, when the fan 14 is started, the air outlet of the air conditioner indoor unit 1 comprises jet air and natural convection air, the air outlet volume is further improved by two air outlet modes of the jet air and the natural convection air, and the air outlet effect of the jet air and the natural convection air can be relatively improved, so that the effect of gain effect is achieved.

It can be understood that the air conditioning indoor unit 1 further comprises a heating mode, wherein air is driven to circulate between the indoor space and the casing 10 by the fan 14, and meanwhile, the heating effect of the air conditioning indoor unit 1 is realized by the heat exchange effect of the heat exchanger 12.
Further, the air is blown to two sides simultaneously through the fan 14, so that the air blowing range of the air conditioner indoor unit 1 is ensured, the running path of air is reduced, the wind intensity of each position of the air conditioner indoor unit 1 is ensured, the installation space is reasonably utilized, and the arrangement rationality of the air conditioner indoor unit 1 is improved.

Example nine:
according to a second aspect of the present invention, there is also provided an air conditioner, comprising: the air conditioning indoor unit 1 according to any of the embodiments described above.
The air conditioner according to the second aspect of the present invention includes the air conditioner indoor unit 1 according to any one of the embodiments, and therefore has all the advantages of the air conditioner indoor unit 1.
Further, the air conditioner further comprises a control system, the control system can acquire an operating mode instruction of the air conditioner, and the air conditioner indoor unit 1 is controlled to perform natural heat convection according to the operating mode instruction, or the self-heating heat convection and the active heat exchange of the fan 14 are performed together, so that different requirements of users are met, and comfort of the users is improved to the greatest extent.
Specifically, the air conditioner indoor unit 1 provided by the invention can be applied to a plurality of products such as household air conditioners, central air conditioner multi-split air conditioners, commercial air curtain machines, commercial air conditioner indoor tail ends and the like.
Example ten:
according to an embodiment of the present invention, there is provided an integrated air conditioning indoor unit 1 combining a jet active mode and a natural convection passive mode, including a first cavity 102, a second cavity 104, an air inlet 106 and an air outlet 108, wherein the air outlet 108 is disposed on a bottom wall of the casing 10 along a first direction, and the second cavity 104 is disposed on two sides of the first cavity 102 along a second direction; the heat exchanger 12 is arranged in the shell 10, and at least one part of the heat exchanger 12 is arranged in the second cavity 104; the fan 14 is disposed in the first cavity 102, and the fan 14 includes an inlet end 1420 and an outlet end 1422, where the inlet end 1420 is in communication with the air inlet 106; the jet nozzle 16 is arranged on the shell 10, the air inlet end of the jet nozzle 16 is communicated with the outlet end 1422, and the air outlet end of the jet nozzle 16 is communicated with the second cavity 104; wherein, part of the air flows through the air inlet 106, enters the shell 10, enters the jet nozzle 16 through the fan 14, is sprayed into the second cavity 104, and is discharged from the air outlet 108; part of the air flow is discharged through an air outlet 108 after being subjected to heat exchange through the air inlet 106 and the part of the heat exchanger 12 positioned in the second cavity 104.
Firstly, the difference from the conventional indoor unit 1 is that the scheme of the indoor unit 1 of the air conditioner provided by the invention has at least two working modes: a strong wind mode in which the blower 14 operates and a natural wind mode in which the blower 14 does not operate. In the natural wind mode that the fan 14 does not work, the natural convection effect of cold air sinking is enhanced by the special arrangement scheme of the heat exchanger 12 and the parameter design of the heat exchanger 12, and the refrigeration effect without the noise and wind sense of the fan 14 is achieved.
Specifically, in the strong wind mode, the fan 14 sucks indoor return air from the jet air inlet 1060 area, passes through the first heat exchanger 12 in the first cavity 102, supplies air to two sides through the jet air duct 18 after the return air is cooled (or heated), jets the return air through the jet air duct 18, forms a high-speed low-pressure fluid area below the jet nozzle 16, and flows in from the area of the guided air inlet 106 through the indoor return air, is mixed with jet air after passing through the heat exchanger 12 in the second cavity 104, and flows downwards from the air outlet 108 into the room along the Z direction. Specifically, as shown in fig. 1 to 3, the first heat exchange portion 120 and the second heat exchange portion 122 enclose a first heat exchange area 126, and after the fan 14 is turned on, air supply of the bidirectional single-jet air duct 18 is achieved. As shown in fig. 4 to 6, the first heat exchange portion 120 and the second heat exchange portion 122 are surrounded to form two first heat exchange areas 126, and after the fan 14 is turned on, bidirectional dual jet air supply is realized. As shown in fig. 7 to 9, the first heat exchange portion 120 and the second heat exchange portion 122 enclose three first heat exchange areas 126, and after the fan 14 is turned on, air supply in the bidirectional three-jet air duct 18 is realized.
In the natural wind mode, the fan 14 does not work completely, so that no jet flow is used for supplying air, the arrangement form of the heat exchanger 12 region is completely relied on to generate the effects of fully exchanging heat and strengthening the cold air sinking effect and reducing the air flow resistance, indoor return air enters the indoor unit from the guided air inlet 106 under the effect of natural convection and then enters the indoor unit downwards from the air outlet 108 along the Z direction, and the indoor cooling is accomplished quietly while the user hardly senses the wind sensation.
The second difference is that the air conditioner indoor unit 1 adopts the blower 14 in the middle to blow air jet flow to two sides, and utilizes jet flow to guide indoor return air to be cooled by the heat exchanger 12 and then mixed and sent out from the lower part. The effect of this is that the fan 14 only provides a small portion of the total air volume, and the diverted return air can reach more than 60% of the total air volume, thereby reducing the load of the fan 14 under the condition of meeting the total capacity, and further achieving the effect of reducing noise.
Further, two fans 14 may be disposed in the first cavity 102, so that air is blown to the second cavities 104 on two sides through one fan 14, thereby further improving the blowing efficiency of the active heat exchange mode of the fan 14.
In order to achieve a better technical effect, the following points need to be satisfied: 1. the heat exchanger 12 is configured to fully cover the primary air intake 1062 and the jet air intake 1060 in the third direction and the first direction to ensure that no wind is allowed to enter through the heat exchanger 12; 2. the projections of the heat exchanger 12 in the first direction and the second direction also cover the air circulation area as much as possible, so as to ensure that the air sinking effect in the two modes is optimal; 3. the heat exchanger 12 requires a drip tray 24 for the condensate in both the positions shown in fig. 6 and 9 to avoid that condensate is not collected in the drip chamber.
The beneficial effects brought by the invention are as follows: the air conditioner indoor unit 1 has two operation modes of strong wind and natural wind, and the strong wind mode can reduce the load of the air quantity of the fan 14 under the condition of meeting the total capacity, so that the effect of reducing noise is achieved to a certain extent; the natural wind mode completely has no noise of the fan 14, and indoor cooling without wind sense is realized by using a special heat exchanger 12 arrangement mode; the air conditioner indoor unit 1 of the invention adopts the arrangement mode that the middle fan 14 supplies air to the two ends, so that the problems of overlarge air duct resistance and uneven jet distribution caused by overlong air supply jet distance can be avoided when the fan 14 is arranged at one end; such an arrangement also reduces the load on the blower 14, improving the compactness of the overall structure.
