Referring to fig. 1 to 3, the utility model discloses an air-conditioning indoor unit 1 includes casing 40, and casing 40's inside is formed with mutually independent first heat transfer wind channel 42 and second heat transfer wind channel 43, and first heat transfer wind channel 42 and second heat transfer wind channel 43 all have the heat transfer air current export, and all are equipped with heat exchanger and fan in first heat transfer wind channel 42 and the second heat transfer wind channel 43 to make the heat transfer air current in first heat transfer wind channel 42 and the second heat transfer wind channel 43 through the fan send out through its self heat transfer air current export. The air paths of the first heat exchange air duct 42 and the second heat exchange air duct 43 are independent from each other, the first heat exchange air duct 42 has a first heat exchange airflow outlet 421, a first heat exchanger 61 and a first fan 51 are arranged in the first heat exchange air duct 42, the first heat exchanger 61 is used for exchanging heat with the airflow in the first heat exchange air duct 42 to generate heat exchange airflow, and the first fan 51 is used for promoting the heat exchange airflow to flow to the first heat exchange airflow outlet 421 and flow out through the first heat exchange airflow outlet 421. Similarly, the second heat exchange air duct 43 has a second heat exchange air outlet 431, and a second heat exchanger 62 and a second fan 52 are disposed therein. The second heat exchanger 62 is configured to exchange heat with the air flow in the second heat exchange air duct 43 to generate a heat exchange air flow, and the second fan 52 is configured to promote the heat exchange air flow to the second heat exchange air flow outlet 431 and flow out through the second heat exchange air flow outlet 431.
In particular, the indoor unit 1 further includes a jet air duct 10, a jet fan 20, and a fresh air duct 70. The jet air duct 10 is independent of the first heat exchange air duct 42 and the second heat exchange air duct 43, and has a jet air inlet 12 and a jet air outlet 11 communicated with an indoor space where the indoor unit 1 of the air conditioner is located. The fresh air duct 70 has one end communicating with the jet inlet 12 and the other end extending outwardly of the housing 40 to facilitate communication of the jet duct 10 with the outdoor environment through the fresh air duct 70. The jet fan 20 is disposed in the jet air duct 10 to controllably drive outdoor fresh air to flow into the jet air duct 10 through the fresh air duct 70, and to flow out through the jet air outlet 11 to be mixed with the heat exchange air flow sent out through the heat exchange air flow outlets of the first heat exchange air duct 42 and the second heat exchange air duct 43.
That is to say, the outdoor fresh air can be introduced into the jet air duct 10 through the fresh air duct 70 by the jet fan 20, the outdoor fresh air sent out through the jet air duct 10 is mixed with the heat exchange air flowing out through the first heat exchange air duct 42 and the second heat exchange air duct 43 to form softer mixed air, thereby avoiding the air-out supercooling or overheating of the indoor unit 1 of the air conditioner, and the outdoor fresh air is continuously introduced into the room in the air supply process of the indoor unit 1 of the air conditioner, so that the comfort experience of the user can be improved in the two aspects of the air-out temperature and the air freshness.
Meanwhile, the jet fan 20 can actively introduce outdoor fresh air into the air supply path of the indoor unit 1 of the air conditioner, compared with the traditional negative pressure passive drainage mode, the active jet fan 20 actively jets the air, the jet air quantity is greatly improved, the air supply distance is increased, the soft air supply effect of the indoor unit 1 of the air conditioner is improved, the whole air supply quantity is increased, and the air supply range is expanded.
In some embodiments, the indoor air conditioner 1 may be a cabinet. At this time, the fans in the first heat exchange air duct 42 and the second heat exchange air duct 43 and the jet fan 20 are all cross flow fans whose rotation axes extend in the vertical direction. That is, the first fan 51, the second fan 52 and the jet fan 20 are all cross-flow fans extending vertically, and the jet air duct 10 is a long air duct extending vertically. The height of the cross flow fan in the vertical direction is high, the air outlet height of the indoor unit 1 of the air conditioner in the vertical direction can be increased, and the air supply range of the indoor unit is expanded. And, three cross-flow fans are combined, so that the air supply quantity of the air conditioner indoor unit 1 can be increased to a great extent. The first and second heat exchangers 61 and 62 are V-shaped or arc-shaped heat exchangers disposed laterally outside the first and second fans 51 and 52, respectively.

One end of the fresh air duct 70, which is communicated with the jet flow air inlet 12, only covers a part of the air inlet area of the jet flow air inlet 12, so that the other air inlet areas of the jet flow air inlet 12 except the part of the air inlet area are communicated with the indoor space where the indoor unit 1 of the air conditioner is located. That is to say, a partial region of the jet air inlet 12 is communicated with the outdoor environment through the fresh air pipe 70, and other regions of the jet air inlet 12 are directly communicated with the indoor space, so that the jet fan 20 can not only promote outdoor fresh air to sequentially enter the jet air duct 10 through the fresh air pipe 70 and the jet air inlet 12, but also promote indoor natural air to enter the jet air duct 10 through the jet air inlet 12, thereby not only ensuring larger jet air volume, but also avoiding the problem that the fresh air pipe 70 is difficult to be applied in practice because the fresh air pipe 70 covers the whole jet air inlet 12 extending vertically, which results in larger volume of the fresh air pipe 70.
Further, the heights of the first heat exchange airflow outlet 421, the second heat exchange airflow outlet 431, the jet flow air outlet 11, and the jet flow air inlet 12 in the vertical direction are all equal, and the positions of the first heat exchange airflow outlet, the second heat exchange airflow outlet, the jet flow air outlet and the jet flow air inlet 12 in the vertical direction are all the same. That is, the tops of the first heat exchange airflow outlet 421, the second heat exchange airflow outlet 431, the jet airflow outlet 11, and the jet airflow inlet 12 are aligned in the vertical direction, and the bottoms of the first heat exchange airflow outlet 421, the second heat exchange airflow outlet 431, the jet airflow outlet 11, and the jet airflow inlet 12 are aligned in the vertical direction. Therefore, the heat exchange airflow flowing out from any height position in the vertical direction through the first heat exchange airflow outlet 421 and the second heat exchange airflow outlet 431 can be mixed with the outdoor fresh air and the natural air flowing out through the jet flow air outlet 11, so that the uniformity of the air supply temperature of the indoor unit 1 of the air conditioner is ensured in the vertical direction, and the phenomenon of uneven air supply temperature of the upper part and the lower part is avoided.
In some embodiments, the other end of the fresh air duct 70 extending outwardly of the cabinet 40 is configured to operatively telescope in a radial direction of the fresh air duct 70. Therefore, before the indoor air conditioner 1 is installed, the fresh air pipe 70 can be retracted, so that the indoor air conditioner 1 is prevented from occupying too much space or interfering with other devices, and the convenience of carrying or transporting the indoor air conditioner 1 is improved; when the indoor unit 1 of the air conditioner is installed, the fresh air duct 70 can be extended out so as to be communicated with the outdoor environment through the wall, and the convenience of installing the indoor unit 1 of the air conditioner is improved.
In some embodiments, the indoor unit 1 further includes a cleaning module 71 disposed at the jet inlet 12 to clean the air flowing through the jet inlet 12 to the jet duct 10. Specifically, the purification module 71 may include a filtration unit and an adsorption unit. The filtering unit is used for filtering outdoor fresh air or larger impurities in indoor air, and the filtering unit can be a dust filtering net, for example. The adsorption unit is used for removing harmful substances in outdoor inlet air or indoor air. In addition, the purification module 71 may further include other units capable of purifying air.

Because the jet flow air outlet 11 is communicated with the through channel 41, and the first heat exchange air duct 42 and the second heat exchange air duct 43 are respectively arranged at two transverse sides of the through channel 41, the indoor natural air and the outdoor fresh air flowing out of the jet flow air outlet 11 are arranged between the two heat exchange air flows flowing out of the two heat exchange air ducts, so that the two heat exchange air flows can be mixed simultaneously, and the uniformity of the air supply temperature of the air conditioner indoor unit 1 can be ensured in the transverse direction.
In some embodiments, the heat exchange airflow outlets of the first heat exchange air duct 42 and the second heat exchange air duct 43 face the front side of the casing 40, and the jet air outlet 11 is formed on the front side of the jet air duct 10. It should be noted that the front side of the casing 40 of the present invention may include the front side of the casing 40, and may also include the inclined front side of the casing 40, as long as the orientation of the heat exchange airflow outlet has a forward direction component to be able to blow air toward the front side of the casing 40.

When the fan and/or the jet fan 20 in the heat exchange air duct operate, a certain negative pressure is generated in the air inducing channel 44, and under the action of the negative pressure, indoor air is introduced into the air inducing channel 44 and is sent out from the air inducing channel 44 to be mixed with heat exchange air flow flowing out of the heat exchange air duct and outdoor fresh air and natural air flowing out of the jet air duct 10, so that the amount of natural air which is not subjected to heat exchange and is introduced into the indoor unit 1 of the air conditioner is increased, and the whole air supply amount is increased.
Further, in the embodiment shown in fig. 4, two lateral duct walls 10f of the jet duct 10 are respectively adjacent to two lateral side walls 41a of the through channel 41, and each lateral duct wall 10f and one lateral side wall 41a adjacent thereto are spaced apart from each other to form an air inducing channel 44 on two lateral outer sides of the jet duct 10, so as to introduce natural air from two lateral sides simultaneously, thereby facilitating more uniform mixing of the natural air and the heat exchange air flow.
Further, in the embodiment shown in fig. 4, the jet air duct 10 is fixedly disposed above the right lower casing 4821, and the jet air duct 10 is closer to the right casing 482 in the through channel 41, so that the width of the air inducing channel 44 adjacent to the left casing 481 is wider than the width of the air inducing channel 44 adjacent to the right casing 482, thereby alleviating the problem of the oversized air conditioning indoor unit 1 caused by the arrangement of the jet air duct 10 behind the right casing 482 to some extent.
Other technical solutions of other embodiments shown in fig. 4 are the same as or similar to those of the embodiments shown in fig. 1 to 3, and are not described herein again.
It should be further understood by those skilled in the art that the terms "upper", "lower", "front", "rear", and the like used in the embodiments of the present invention to indicate the orientation or the positional relationship are based on the actual use state of the air conditioning indoor unit 1, and these terms are only used for convenience of description and understanding of the technical solution of the present invention, and do not indicate or imply that the indicated device must have a specific orientation, be configured and operated in a specific orientation, and therefore, should not be construed as limiting the present invention.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
