When a feature "includes or contains" one or some of the features it covers, unless otherwise specifically described, this indicates that other features are not excluded and may further include other features.

[0031] In the description of the present embodiment, the description with reference to the terms "one embodiment", "some embodiments", "some examples", "an example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0032] The utility model provides an air conditioner indoor unit 10. The utility model does not limit the form of the air conditioner indoor unit 10, and the air conditioner indoor unit 10 can be a vertical indoor unit, a wall-mounted indoor unit, a window indoor unit or other indoor units in various forms.

[0033] Figure 1 is a schematic cross-sectional view of an air-conditioning indoor unit 10 according to an embodiment of the present utility model. Figure 2 1 is a schematic diagram of the air outlet principle of an air conditioner indoor unit 10 according to an embodiment of the utility model. Figure 1 and Figure 2 An embodiment of a vertical type indoor unit is shown.

[0034] like Figure 1 and Figure 2 As shown, the air conditioner indoor unit 10 of this embodiment may include a housing 100 and a first induced draft fan 210, wherein a first lateral side of the housing 100 is provided with a first air outlet 101 and a first induced draft port 103, a first induced draft duct 110 is formed in the housing 100, an inlet of the first induced draft duct 110 is communicated with the first induced draft port 103, and an outlet of the first induced draft duct 110 is communicated with the first air outlet 101. The first induced draft fan 210 is disposed in the first induced draft duct 110, and is used to cause indoor air to flow to the first air outlet 101 through the first induced draft port 103 and the first induced draft duct 110.

[0035] With the above structure, when the air is blown out through the first air outlet 101, the first induced draft fan 210 can introduce indoor air into the outlet air flow through the first air outlet 103 and the first induced draft duct 110. The outlet air temperature after the outlet air flow is mixed with the indoor air will not be too cold or too hot, which is beneficial to improving the user's blowing experience when passing near the first air outlet 101.

[0036] In an optional embodiment, a first air inlet 105 is opened on the first longitudinal side of the shell 100, and a first heat exchange air duct 130 is formed in the shell 100. The inlet of the first heat exchange air duct 130 is connected to the first air inlet 105, and the outlet is connected to the first air outlet 101, and the outlet of the first air duct 110 is formed on the air duct wall of the first heat exchange air duct 130.

[0037] With the above structure, after the indoor air enters the first heat exchange duct 130 through the first air inlet 103 and the first air duct 110, it can flow along the first heat exchange duct 130 for a path and then be blown out from the first air outlet 101. When flowing through the first heat exchange duct 130, the indoor air can be more evenly mixed with the outlet air flow during the flow process, thereby improving the uniformity of the outlet air temperature.

[0038] In some embodiments, the air conditioning indoor unit 10 may also include a first heat exchanger 310 and a first heat exchange fan 230, wherein the first heat exchanger 310 is arranged in the shell 100 adjacent to the first air inlet 105, and is used to exchange heat with the indoor air flowing in from the first air inlet 105, and the first heat exchange fan 230 is arranged in the first heat exchange air duct 130, and is used to promote the airflow after heat exchange to be blown out from the first air outlet 101 along the first heat exchange air duct 130.

[0039] The first air outlet 101 is the main air outlet of the air conditioner indoor unit 10. Without introducing indoor air through the first air inlet 103, if the air conditioner indoor unit 10 is in cooling mode, the air flow blown out from the first air outlet 101 is cooling air flow; if the air conditioner indoor unit 10 is in heating mode, the air flow blown out from the first air outlet 101 is heating air flow. If the air conditioner indoor unit 10 also has purification, dehumidification and other functions, the air flow blown out from the first air outlet 101 can be the corresponding purification air flow or dehumidification air flow.

[0040] It should be noted that in the embodiment shown in the accompanying drawings of the present utility model, the lateral direction of the shell 100 refers to the left and right direction, for example, the first air outlet 101 and the first air inlet 103 are located on the left side of the shell 100, and the longitudinal direction of the shell 100 refers to the front and back direction, for example, the first air inlet 105 is located on the rear side of the shell 100.

[0041] In an optional embodiment, a first horizontal swing blade 431 and a first vertical swing blade 441 are provided in the first heat exchange air duct 130. The first horizontal swing blade 431 and the first vertical swing blade 441 are arranged in sequence along the air outlet direction of the heat exchange air duct. When the air is blown out through the first air outlet 101, the first horizontal swing blade 431 can swing up and down in a controlled manner, and the first vertical swing blade 441 can swing left and right in a controlled manner. The first horizontal swing blade 431 and the first vertical swing blade 441 break up the airflow in the first heat exchange air duct 130 through their respective swings, so that the air outlet of the first air outlet 101 is softer.

[0042] Further, the first vertical swing blade 441 can be located at a side of the outlet of the first air duct 110 away from the first air outlet 101. In this way, when the air conditioner indoor unit 10 is in cooling mode, the first vertical swing blade 441 can be better wrapped by cold air, thereby reducing the condensation problem.

[0043] It should be noted that the above-mentioned first horizontal swing blade 431 and the first vertical swing blade 441 are widely used in the field of air conditioning, and their structures and principles are well known to those skilled in the art and will not be described herein.

[0044] In an optional embodiment, the inlet of the first air duct 110 may be in a flared shape, thereby increasing the air inlet area of ​​the first air outlet 103 and further increasing the mixed air volume in the outlet air flow.

[0045] It can be understood that introducing indoor air into the outlet air flow does not change the supply of cooling or heat of the air-conditioning indoor unit 10, that is, the cooling and heating speeds of the air-conditioning indoor unit 10 remain unchanged, and the more indoor air is introduced, the closer the outlet air temperature of the outlet air flow is to the indoor temperature, and the wind feeling when the user passes near the air-conditioning indoor unit 10 is more natural, which can effectively prevent the problem of human discomfort caused by cold or hot air blowing directly on the human body.

[0046] In an optional embodiment, the outlet of the first air induced duct 110 is inclined toward the first air outlet 101, so that the indoor air can be inclined to flow into the first heat exchange duct 130 after flowing out of the first air induced duct 110. This can reduce the air outlet resistance in the first heat exchange duct 130 and allow the air flow to be blown out from the first air outlet 101 more smoothly.

[0047] Furthermore, a first air induction plate 421 may be provided at the outlet of the first air induction duct 110, and the first air induction plate 421 is used to rotate around a vertical axis in a controlled manner to adjust the air outlet angle at the outlet of the first air induction duct 110. When adjusting the air outlet angle, the first air induction plate 421 will also change the outlet opening of the first air induction duct 110, thereby reasonably controlling the amount of air induction.

[0048] In an optional embodiment, the number of the first air inlets 103 may be two, and the two first air inlets 103 are arranged on both sides of the first air outlet 101 along the longitudinal direction of the shell 100, and the two first air inlets 103 are each connected to the first air outlet 101 through a first air duct 110, and a first air duct fan 210 is provided in each of the two first air ducts 110.

[0049] With the above structure, when the air is blown out through the first air outlet 101, the indoor air can be introduced from the two first air inlets 103 at the same time, which is not only conducive to increasing the mixed air volume of the outlet air flow, making the outlet air temperature of the outlet air flow closer to the indoor temperature, but also can make the mixing of indoor air and the outlet air flow more uniform, avoiding the problem of alternating hot and cold during the air outlet process.

[0050] Furthermore, the two first air inlet ports 103 may be symmetrically or asymmetrically arranged on both longitudinal sides of the first air outlet 101 , and the above-mentioned first air inlet plate 421 may be arranged at the outlet of each first air inlet duct 110 .

[0051] In one example, a first air guide plate 411 may be provided at the first air outlet 101, and the number of the first air guide plates 411 may be two or more, and they are arranged sequentially along the longitudinal direction of the first air outlet 101. By driving each first air guide plate 411 to rotate around its vertical axis in a controlled manner, the opening and closing of the first air outlet 101 can be controlled, and the air outlet direction of the first air outlet 101 can be adjusted.

[0052] In an optional embodiment, the second lateral side of the housing 100 is respectively provided with a second air outlet 102 and a second air induction port 104, and a second air induction duct 120 is formed in the housing 100, and the inlet of the second air induction duct 120 is communicated with the second air induction port 104, and the outlet is communicated with the second air outlet 102. The air conditioner indoor unit 10 further includes a second air induction fan 220, which is arranged in the second air induction duct 120, and is used to cause the indoor air to flow to the second air outlet 102 through the second air induction port 104 and the second air induction duct 120.

[0053] By adopting the above structure, during the operation of the air-conditioning indoor unit 10, indoor air can be introduced into the first air outlet 101 through the first air inlet 103, and indoor air can be introduced into the second air outlet 102 through the second air inlet 104, so that when the air-conditioning indoor unit 10 discharges air through the first air outlet 101 and the second air outlet 102 at the same time, a mirrored wind curtain is formed on both sides of the air-conditioning indoor unit 10, giving the user a better air outlet experience.

[0054] In an optional embodiment, a second air inlet 106 is opened on the second longitudinal side of the shell 100, and a second heat exchange air duct 140 is formed in the shell 100. The inlet of the second heat exchange air duct 140 is connected to the second air inlet 106, and the outlet is connected to the second air outlet 102, and the outlet of the second air duct 120 is formed on the air duct wall of the second heat exchange air duct 140.

[0055] With the above structure, after the indoor air enters the second heat exchange duct 140 through the second air inlet 104 and the second air duct 120, it can flow along the second heat exchange duct 140 for a path and then be blown out from the second air outlet 102. When flowing through the second heat exchange duct 140, the indoor air can be more evenly mixed with the outlet air flow during the flow process, thereby improving the uniformity of the outlet air temperature.

[0056] In some embodiments, the air conditioning indoor unit 10 may further include a second heat exchanger 320 and a second heat exchange fan 240, wherein the second heat exchanger 320 is arranged in the shell 100 adjacent to the second air inlet 106 for exchanging heat with the indoor air flowing in from the second air inlet 106, and the second heat exchange fan 240 is arranged in the second heat exchange air duct 140 for causing the airflow after heat exchange to be blown out from the second air outlet 102 along the second heat exchange air duct 140.

[0057] The second air outlet 102 is another main air outlet of the air conditioner indoor unit 10. Without the indoor air introduced by the second air inlet 104, if the air conditioner indoor unit 10 is in cooling mode, the air flow blown out from the second air outlet 102 is cooling air flow; if the air conditioner indoor unit 10 is in heating mode, the air flow blown out from the second air outlet 102 is heating air flow. If the air conditioner indoor unit 10 also has purification, dehumidification and other functions, the air flow blown out from the second air outlet 102 can be the corresponding purification air flow or dehumidification air flow.

[0058] It should be noted that in the embodiments shown in the accompanying drawings of the present utility model, the lateral direction of the shell 100 refers to the left-right direction, for example, the second air outlet 102 and the second air inlet 104 are located on the right side of the shell 100, and the longitudinal direction of the shell 100 refers to the front-back direction, for example, the second air inlet 106 is located on the front side of the shell 100.

[0059] In this embodiment, the first heat exchange fan 230 , the second heat exchange fan 240 , the first induced draft fan 210 , and the second induced draft fan 220 may all be cross-flow fans.

[0060] In an optional embodiment, a second horizontal swing blade 432 and a second vertical swing blade 442 are provided in the second heat exchange air duct 140. The second horizontal swing blade 432 and the second vertical swing blade 442 are arranged in sequence along the air outlet direction of the heat exchange air duct. When the air is blown out through the second air outlet 102, the second horizontal swing blade 432 can swing up and down in a controlled manner, and the second vertical swing blade 442 can swing left and right in a controlled manner. The second horizontal swing blade 432 and the second vertical swing blade 442 break up the airflow in the second heat exchange air duct 140 through their respective swings, so that the air outlet of the second air outlet 102 is softer.

[0061] Further, the second vertical swing blade 442 can be located at a side of the outlet of the second air duct 120 away from the second air outlet 102. In this way, when the air conditioner indoor unit 10 is in cooling mode, the second vertical swing blade 442 can be better wrapped by cold air, thereby reducing the condensation problem.

[0062] Similarly, the inlet of the second air duct 120 may be in a flared shape, thereby increasing the air inlet area of ​​the second air duct 104 and further increasing the mixed air volume in the outlet airflow.

[0063] The outlet of the second air induced duct 120 is inclined toward the second air outlet 102, so that the indoor air can be inclinedly merged into the second heat exchange duct 140 after flowing out from the second air induced duct 120. This can reduce the air outlet resistance in the second heat exchange duct 140 and make the air flow blow out from the second air outlet 102 more smoothly.

[0064] A second air induction plate 422 may be provided at the outlet of the second air induction duct 120, and the second air induction plate 422 is used to rotate around a vertical axis in a controlled manner to adjust the air outlet angle at the outlet of the second air induction duct 120. When adjusting the air outlet angle, the second air induction plate 422 will also change the outlet opening of the second air induction duct 120, thereby reasonably controlling the amount of air induction.

[0065] The number of the second air inlets 104 can be two, and the two second air inlets 104 are arranged on both sides of the second air outlet 102 along the longitudinal direction of the shell 100. The two second air inlets 104 are respectively connected to the second air outlet 102 through a second air duct 120, and a second air duct fan 220 is provided in each of the two second air ducts 120.

[0066] With the above structure, when the air is blown out through the second air outlet 102, indoor air can be introduced from the two second air inlets 104 at the same time. This is not only conducive to increasing the mixed air volume of the outlet air flow, making the outlet air temperature of the outlet air flow closer to the indoor temperature, but also can make the mixing of indoor air and the outlet air flow more uniform, avoiding the problem of alternating hot and cold during the air outlet process.

[0067] Furthermore, the two second air inlet ports 104 may be symmetrically or asymmetrically arranged on both longitudinal sides of the second air outlet port 102 , and the above-mentioned second air inlet plate 422 may be arranged at the outlet of each second air inlet duct 120 .

[0068] The second air outlet 102 may be provided with a second air guide plate 412, and the number of the second air guide plates 412 may be two or more, and they are arranged in sequence along the longitudinal direction of the second air outlet 102. By driving each second air guide plate 412 to rotate around its vertical axis in a controlled manner, the opening and closing of the second air outlet 102 can be controlled, and the air outlet direction of the second air outlet 102 can be adjusted.

[0069] In an optional embodiment, the second air outlet 102 and the first air outlet 101 are symmetrically arranged on both sides of the housing 100, so that the air conditioner indoor unit 10 can symmetrically eject air outward. In this embodiment, the first air outlet 101 and the second air outlet 102 are located in the middle of the left and right sides of the housing 100.

[0070] Furthermore, the first heat exchange air duct 130 can extend from the first air inlet 105 from the back to the front, gradually to the left to the first air outlet 101, and the second heat exchange air duct 140 can extend from the second air inlet 106 from the front to the back, gradually to the right to the second air outlet 102. In this way, the first heat exchanger 310, the second heat exchanger 320, the first heat exchange fan 230 and the second heat exchange fan 240 can be installed in the housing 100 in a relatively reasonable manner, making the internal layout of the housing 100 more reasonable and compact.

[0071] The air conditioner indoor unit 10 of the embodiment of the utility model is suitable for the middle position in a large space environment, such as a supermarket, an office building, etc. Since the first heat exchanger 310 and the second heat exchanger 320 have a large power and a high energy efficiency, the outlet air temperature has a large difference from the indoor temperature. In order to provide a better air outlet experience and reduce energy consumption, the air conditioner indoor unit 10 can be controlled in the following manner.

[0072] First, a human sensor can be set at the first air outlet 101 and the second air outlet 102 of the air conditioner indoor unit 10. The sensing angle of the human sensor can be 160° and the sensing distance can be 2.5m, which is used to detect whether there is a human body in the surrounding area. The air conditioner indoor unit 10 can have a closed wind curtain mode, a close-distance wind curtain mode, and a normal wind curtain mode.

[0073] In the closed air curtain mode, only the first heat exchange fan 230 and the second heat exchange fan 240 operate normally, and the two first induced draft fans 210 and the two second induced draft fans 220 are stopped.

[0074] In the close-range wind curtain mode, it is assumed that the flow of people in the environment where the air-conditioning indoor unit 10 is located is small, and the first heat exchange fan 230 and the second heat exchange fan 240 keep running. If the left human sensor detects a human body, the two first induced draft fans 210 are turned on, and if the right human sensor detects a human body, the two second induced draft fans 220 are turned on. In this way, the energy loss problem caused by starting the first induced draft fan 210 and the second induced draft fan 220 when no one is passing by can be avoided.

[0075] In the normal wind curtain mode, it is assumed that there is a large flow of people in the environment where the air-conditioning indoor unit 10 is located, and the first heat exchange fan 230, the second heat exchange fan 240, the two first induced draft fans 210 and the two second induced draft fans 220 are running at the same time. In this way, the noise change experience caused by frequent starting and stopping of the two first induced draft fans 210 and the two second induced draft fans 220 can be avoided.

[0076] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
