With this air outlet mode, the air outlet direction is generally the same whether in cooling or heating mode. If the conventional downward air outlet mode is used, the cold air will blow directly at people at a certain angle. In addition, theoretically, the density of cold air is greater than that of hot air, so it is more suitable for the upward air outlet mode; and when the temperature of the feet is higher than that of the head, the comfort of the person is better, so hot air is more suitable for the downward air outlet mode.

[0003] In order to improve the comfort of air supply, the relevant technology discloses an air-conditioning indoor unit, comprising: a heat exchange shell, which is provided with a heat exchange outlet, and the heat exchange shell includes a heat exchange bottom shell, and the heat exchange outlet is located on the front side of the heat exchange bottom shell; an air uniforming arm, which is internally provided with an air uniforming component facing the heat exchange outlet, and the air uniforming component is used to introduce indoor air into the heat exchange outlet, and mix it with the air at the heat exchange outlet and then blow it out; wherein the air uniforming arm is arranged on the heat exchange bottom shell.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] In the related art, the air leveling component works to introduce the indoor air into the heat exchange outlet, which is active air leveling. Since the air leveling component needs to work, it will generate noise from the air leveling component and increase the energy consumption of the indoor unit.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0008] The embodiments of the present disclosure provide an indoor unit of an air conditioner and an air conditioner to solve the problems of working noise of a wind uniforming component and energy consumption of the indoor unit in the related art.

[0009] According to a first aspect of an embodiment of the utility model, an indoor unit of an air conditioner is provided, comprising: a heat exchange body, comprising a heat exchange shell and a heat exchanger arranged in the heat exchange shell, the heat exchange shell being provided with a heat exchange air outlet for blowing out heat exchange air; a uniform wind arm, provided with a through hole passing through it, in a uniform wind mode, the uniform wind arm is arranged below the heat exchange body and the first end of the through hole faces the heat exchange air outlet, for introducing indoor air from the second end of the through hole and flowing to the first end of the through hole to mix with the heat exchange air flowing out of the heat exchange air outlet.

[0010] According to a second aspect of the embodiments of the utility model, an air conditioner is provided, comprising an indoor unit of the air conditioner as described in any one of the above embodiments.

[0011] The indoor unit of the air conditioner and the air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0012] When the heat exchange outlet blows out air, a low-pressure area will be generated at the heat exchange outlet, so that the indoor air near the low-pressure area will be sucked into the low-pressure area, and then merged into the heat exchange air for mixing. This part of the indoor air passively attracted is passive uniform wind.

[0013] In the uniform wind mode, the uniform wind arm is arranged below the heat exchange body, a part of the indoor air is sucked into the low pressure area from between the uniform wind arm and the heat exchange body, and a part of the indoor air flows to the low pressure area through the second end of the through hole and the first end of the through hole, and both parts of the indoor air form passive uniform wind, increasing the uniform wind volume of the passive uniform wind. When the uniform wind volume of the passive uniform wind is large enough, there is no need to set the uniform wind component in the related art, thereby avoiding the noise problem of the uniform wind component and reducing the energy consumption of the air conditioner.

[0050] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0051] Embodiment 1:

[0052] Combination Figure 1-17 As shown, an embodiment of the present disclosure provides an air-conditioning indoor unit 100, the air-conditioning includes the indoor unit 100 and an outdoor unit, the indoor unit 100 and the outdoor unit are connected by a connecting pipe to realize the circulation of refrigerant between the indoor unit 100 and the outdoor unit.

[0053] The indoor unit 100 includes a heat exchange body 1 and an air uniforming arm 2 .

[0054] The heat exchange body 1 includes a heat exchange shell 11, which defines an air duct 122, in which a heat exchanger 123 is arranged, and the heat exchange shell 11 is provided with a heat exchange air outlet 114 connected to the air duct 122, and the heat exchange air outlet 114 is used to blow out heat exchange air. Specifically, the heat exchange body 1 also includes a fan 121 arranged in the air duct 122, and the heat exchange shell 11 is also provided with a heat exchange air inlet. Driven by the fan 121, air enters from the heat exchange air inlet, and forms heat exchange air after heat exchange with the heat exchanger 123, and the heat exchange air is blown out from the heat exchange air outlet 114.

[0055] The wind uniforming arm 2 is movably connected to the heat exchange body 1, such as a rotating connection or a sliding connection. The wind uniforming arm 2 can be in a closed position (such as a closed position) relative to the heat exchange body 1 to close the heat exchange outlet 114. Figure 1 as shown) and the working position of opening the heat exchange air outlet 114 (as shown Figure 6 shown).

[0056] like Fig.15 As shown, the wind uniforming arm 2 is provided with a first air inlet and outlet 211 and a second air inlet and outlet 212 that are connected. In the working position, the wind uniforming arm 2 is used to introduce air from one of the first air inlet and outlet 211 and the second air inlet and outlet 212 and blow it out from the other. At this time, the first air inlet and outlet 211 and the second air inlet and outlet 212 used to introduce air is the uniform air inlet, and the other is the uniform air outlet.

[0057] like Fig.15 As shown, the wind uniforming arm 2 includes a wind uniforming shell 21 and a wind uniforming component arranged in the wind uniforming shell 21. The wind uniforming shell 21 is provided with a first air inlet and outlet 211 and a second air inlet and outlet 212. One of the first air inlet and outlet 211 and the second air inlet and outlet 212 serves as an air inlet (wind uniforming inlet), and the other serves as an air outlet (wind uniforming outlet). The wind uniforming component is used to introduce air (indoor air or heat exchange air) from the wind uniforming inlet and blow it out from the wind uniforming outlet.

[0058] In one embodiment, in the working position, the wind uniforming arm 2 is used to introduce indoor air (indoor wind) from the first air inlet and outlet 211 and blow it from the second air inlet and outlet 212 to the heat exchange outlet 114, so as to achieve mixing of indoor wind and heat exchange air, so as to change the temperature and / or outlet direction of the heat exchange air and achieve soft wind.

[0059] In another embodiment, in the working position, the wind uniforming arm 2 is used to introduce the heat exchange air blown out of the heat exchange air outlet 114 from the second air inlet and outlet 212 and blow it out from the first air inlet and outlet 211 to change the outlet direction of the heat exchange air.

[0060] When the air uniforming arm 2 switches from the working position to the closed position, the air uniforming arm 2 moves toward the heat exchange body 1 to close the heat exchange air outlet 114 in the closed position, thereby reducing the area of ​​the air uniforming arm 2 exposed to the outside and reducing dust accumulation on the air uniforming arm 2.

[0061] The indoor unit 100 further includes a connecting arm 3 , which is connected between the wind uniforming arm 2 and the heat exchange body 1 , and at least one of the wind uniforming arm 2 and the heat exchange body 1 is movably connected to the connecting arm 3 .

[0062] The connecting arm 3 is movably connected (for example, rotating or sliding) to the heat exchange body 1, and the air uniforming arm 2 is switched between the working position and the closed position by adjusting the position of the connecting arm 3 relative to the heat exchange body 1. At this time, the connecting arm 3 and the air uniforming arm 2 are movably connected (for example, rotating or sliding) or fixedly connected.

[0063] The connecting arm 3 is movably connected (for example, rotating or sliding) to the uniform wind arm 2, and the uniform wind arm 2 is switched between the working position and the closed position by adjusting the position of the uniform wind arm 2 relative to the connecting arm 3. At this time, the connecting arm 3 and the heat exchange body 1 are movably connected (for example, rotating or sliding) or fixedly connected.

[0064] At least one of the air uniforming arm 2 and the heat exchange body 1 is rotatably connected to the connecting arm 3 so that the air uniforming arm 2 can move between a closed position and a working position relative to the heat exchange body 1 .

[0065] Compared with the sliding connection, the rotating connection does not require the design of a slide rail, occupies less space, and can make the indoor unit 100 more compact.

[0066] like Figure 3 , Figures 6 to 8 As shown, the connecting arm 3 includes a first connecting section 31 , a second connecting section 32 and a third connecting section 33 .

[0067] The first connecting section 31 is connected to the heat exchange body 1; the second connecting section 32 is connected to the uniform wind arm 2; the third connecting section 33 is connected between the first connecting section 31 and the second connecting section 32, and there are angles between the first connecting section 31 and the third connecting section 33 and between the second connecting section 32 and the third connecting section 33. The first connecting section 31 and the second connecting section 32 are located on the same side of the third connecting section 33.

[0068] In the working position, the uniform wind arm 2 is located below the heat exchange body 1. In the closed position, the uniform wind arm 2 moves toward the heat exchange body 1 and moves to a position that closes the heat exchange air outlet 114. The connecting arm 3 is generally U-shaped, so that when the connecting arm 3 rotates relative to the heat exchange body 1, it can drive the uniform wind arm 2 to move between the working position and the closed position.

[0069] like Figure 1 , Figure 4and Figure 5 As shown, the heat exchange shell 11 includes a front side wall 111, a heat exchange bottom wall 112 and a main body side wall 113, and the front side wall 111, the heat exchange bottom wall 112 and the main body side wall 113 jointly surround a heat exchange air outlet 114; wherein, the main body side wall 113 is provided with a mounting groove 1131, and in the closed position, the wind uniforming arm 2 is located in the mounting groove 1131.

[0070] There are two main body side walls 113, which are arranged opposite to each other. One of the main body side walls 113 is connected to one end of the front side wall 111 and the heat exchange bottom wall 112 in the length direction, and the other main body side wall 113 is connected to the other end of the front side wall 111 and the heat exchange bottom wall 112 in the length direction.

[0071] The main body side wall 113 is provided with a mounting groove 1131, and in the closed position, the wind uniform arm 2 is located in the mounting groove 1131, so that the length of the wind uniform arm 2 protruding forward from the front surface of the heat exchange main body 1 in the closed position can be reduced, or, in the closed position, the front surface of the wind uniform arm 2 is flush with the front surface of the heat exchange main body 1, so that the aesthetics of the indoor unit 100 can be further improved. Alternatively, in the closed position, the front surface of the wind uniform arm 2 is located at the rear side of the front surface of the heat exchange main body 1, that is, the wind uniform arm 2 does not protrude forward from the front surface of the heat exchange main body 1.

[0072] The mounting groove 1131 penetrates the heat exchange bottom wall 112 , so that when the wind uniforming arm 2 moves from the working position to the closed position driven by the connecting arm 3 , interference between the wind uniforming arm 2 and the heat exchange bottom wall 112 can be avoided.

[0073] Along the air outlet direction of the heat exchange outlet 114, the top wall 1143 of the heat exchange outlet is inclined upward; the uniform wind arm 2 includes a first uniform wind side wall 213 adapted to the top wall 1143 of the heat exchange outlet, wherein in the closed position, the first uniform wind side wall 213 corresponds to the top wall 1143 of the heat exchange outlet.

[0074] The top wall 1143 of the heat exchange air outlet is located below the front side wall, connected to the front side wall, and located on the same side of the air duct as the front side wall.

[0075] In the closed position, along the air outlet direction of the heat exchanger outlet 114, the first uniform wind side wall 213 is inclined upward. Compared with the downward inclination, the upward inclination enables the uniform wind arm 2 to be more easily inserted into the mounting groove 1131 in the closed position, thereby enhancing the tolerance for assembly of the uniform wind arm 2 to the heat exchange body 1 in the closed position and reducing the requirements for the manufacturing precision of the uniform wind arm 2 and the heat exchange body 1.

[0076] The wind uniforming housing 21 includes a second wind uniforming side wall 214 . In the closed position, the bottom wall surface of the second wind uniforming side wall 214 is parallel to or located in the same plane as the bottom wall surface of the heat exchange bottom wall 112 .

[0077] like Figure 5 As shown, in the closed position, when the bottom wall surface of the second uniform wind side wall 214 is parallel to or located in the same plane as the bottom wall surface of the heat exchange bottom wall 112, the transition between the second uniform wind side wall 214 and the heat exchange bottom wall 112 can be achieved, thereby improving the aesthetics of the indoor unit 100.

[0078] The heat exchange bottom wall 112 is inclined upward in the direction from back to front. In the closed position, the second uniform wind side wall 214 is matched with the heat exchange bottom wall 112, that is, the second uniform wind side wall 214 is inclined upward in the direction from back to front.

[0079] like Figure 5 As shown, in the closed position, the outer surface of the air uniforming shell 21 smoothly transitions with the front side wall and the heat exchange bottom wall to improve the aesthetics of the indoor unit 100 and avoid affecting the appearance of the indoor unit 100 due to the setting of the air uniforming arm 2.

[0080] The heat exchange body 1 further includes an air guide plate 5 , which is disposed in the air duct 122 and is used to adjust the flow direction of the heat exchange air flowing out through the heat exchange air outlet 114 .

[0081] The air guide plate 5 is movably connected to the side wall of the air duct 122, for example, rotatably connected. The air guide plate 5 rotates relative to the side wall of the air duct 122 to adjust the flow direction of the heat exchange air and play a role in guiding the air.

[0082] In the closed position, Fig. 9 As shown, the wind uniforming arm 2 is located outside the wind guide plate 5, so that the wind uniforming arm 2 will not affect the wind guide plate 5 when switching between the working position and the closed position, and the wind guide plate 5 does not need to move.

[0083] The present application also provides an air conditioner, comprising an indoor unit 100 of the air conditioner as described in any one of the above embodiments.

[0084] The air conditioner provided in the present application includes the indoor unit 100 of the air conditioner as described in any one of the above embodiments, and thus has all the beneficial effects of the indoor unit 100 of the air conditioner as described in any one of the above embodiments, which will not be repeated here.

[0085] The air conditioner also includes a first driving device and a second driving device.

[0086] The first driving device is connected to the uniform wind arm 2 for driving the uniform wind arm 2 to move between the closed position and the working position relative to the heat exchange body 1; the second driving device is connected to the air guide plate 5 for driving the air guide plate 5 to move relative to the heat exchange outlet 114; the controller is connected to both the first driving device and the second driving device to control the first driving device and the second driving device to respectively drive the uniform wind arm 2 and the air guide plate 5 to move, so as to realize at least one of the shutdown mode, the refrigeration direct blowing prevention mode, the uniform wind mode, the heating downward blowing mode and the surrounding air supply mode. In the shutdown mode, the refrigeration direct blowing prevention mode, the uniform wind mode, the heating downward blowing mode and the surrounding air supply mode, the uniform wind arm 2 is respectively located at the closed position, the refrigeration direct blowing prevention position, the uniform wind position, the heating downward blowing position and the surrounding air supply position, and the working position of the uniform wind arm includes the refrigeration direct blowing prevention position, the uniform wind position, the heating downward blowing position and the surrounding air supply position.

[0087] The first driving device includes a first motor 4. The first motor 4 directly drives the wind uniforming arm 2 to move, or drives the wind uniforming arm 2 to move through a transmission mechanism such as a gear.

[0088] When the connecting arm 3 is movably connected to the heat exchange body 1 and the connecting arm 3 is movably connected to the uniform wind arm 2, the position of the connecting arm 3 relative to the heat exchange body 1 is adjusted, and the position of the uniform wind arm 2 relative to the connecting arm 3 is adjusted to jointly achieve a change in the position of the uniform wind arm 2 relative to the heat exchange body 1.

[0089] There are multiple first motors, at least one of which is driven and connected to the connecting arm 3 to drive the connecting arm 3 to rotate relative to the heat exchange body 1, and the remaining first motors 4 are driven and connected to the uniform wind arm 2 to drive the uniform wind arm 2 to rotate relative to the connecting arm 3.

[0090] The second driving device includes a second motor 7. The second motor 7 directly drives the air guide plate 5 to move, or drives the air guide plate 5 to move through a transmission mechanism such as a gear, so as to adjust the air outlet direction of the heat exchange air outlet 114.

[0091] In shutdown mode, the wind uniforming arm 2 closes the heat exchange outlet 114 , the angle between the wind uniforming arm 2 and the horizontal plane is 67°, the front end of the wind uniforming arm 2 is higher than the rear end, and the wind uniforming arm 2 is located on the outside of the wind guide plate 5 .

[0092] like Fig.11 In the cooling and direct blowing prevention mode, the wind arm 2 moves toward the working position and rotates downward by 34°. The angle between the wind arm 2 and the horizontal plane is 20°, and the front end of the wind arm 2 is higher than the rear end, located at +20°. The angle between the wind guide plate 5 and the horizontal plane is 20°, and the front end of the wind guide plate 5 is higher than the rear end, located at +20°. At this time, the indoor air is introduced through the first air inlet and outlet 211 and blown from the second air inlet and outlet 212 to the heat exchange outlet 114. The wind arm 2 participates in the air guiding, which can achieve a 15° rise in cold air to prevent the cold air from blowing directly on the user.

[0093] like Fig.10 In the uniform wind mode, the uniform wind arm 2 is horizontally arranged, the angle between the wind guide plate 5 and the horizontal plane is 20°, and the front end of the wind guide plate 5 is lower than the rear end, and is located at a position of -20°. At this time, the indoor air is introduced through the first air inlet and outlet 211 and blown to the heat exchange outlet 114 from the second air inlet and outlet 212, increasing the uniform wind volume (the amount of indoor air sucked into the first air inlet and outlet 211), providing comfortable and soft wind, cool but not cold. Among them, the arrow at G indicates the flow direction of passive uniform wind, and the arrow at F indicates the flow direction of heat exchange air.

[0094] like Fig.12 As shown, in the heating downward blowing mode, the angle between the wind uniform arm 2 and the horizontal plane is 70°, and the front end of the wind uniform arm 2 is higher than the rear end, located at +70°, and the angle between the wind guide plate 5 and the horizontal plane is 30°, and the front end of the wind guide plate 5 is lower than the rear end, located at -20°. At this time, the indoor air is introduced through the first air inlet and outlet 211 and blown from the second air inlet and outlet 212 to the heat exchange outlet 114. The wind uniform arm 2 participates in the air guiding, and the hot air can be blown vertically downward, warming the body first and the feet first.

[0095] like Fig.13 As shown, in the encircling air supply mode, the angle between the wind uniform arm 2 and the horizontal plane is 32°, and the front end of the wind uniform arm 2 is higher than the rear end, located at +32°, and the angle between the wind guide plate 5 and the horizontal plane is 20°, and the front end of the wind guide plate 5 is lower than the rear end, located at -20°. At this time, the indoor air is introduced through the first air inlet and outlet 211 and blown from the second air inlet and outlet 212 to the heat exchange outlet 114. The wind uniform arm 2 participates in the air guiding, and the upper and lower air flows are discharged. The indoor temperature is more uniform, the vertical temperature difference is small, and the user feels good.

[0096] like Fig.14 As shown, the heat exchange shell 11 includes a heat exchange bottom wall 112. In the uniform wind mode, the uniform wind arm 2 is arranged below the heat exchange bottom wall 112, and the ratio of the maximum distance L2 and the minimum distance L1 between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is in the range of 1.1-2.0.

[0097] The heat exchange outlet 114 and the second air inlet and outlet 212 will respectively generate low-pressure areas at the heat exchange outlet 114 and the second air inlet and outlet 212 when blowing out air, so that the indoor air near the low-pressure area will be sucked into the low-pressure area and then merged into the heat exchange air for mixing. This part of the indoor air passively attracted is passive uniform wind.

[0098] In the uniform wind mode, the uniform wind arm 2 is arranged below the heat exchange bottom wall 112, and a passive air induction distance is formed between the uniform wind arm 2 and the heat exchange bottom wall 112. The existence of the passive air induction distance enables the indoor air to flow from the gap between the air outlet top of the second air inlet and outlet 212 and the heat exchange bottom wall 112 to the second air inlet and outlet 212 and the heat exchange air outlet 114, thereby achieving passive uniform wind, thereby allowing more indoor air to mix with the heat exchange air, improving the mixing degree of the indoor air and the heat exchange air, and improving the air supply comfort in the air-conditioned room.

[0099] In the uniform wind mode, the distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 will affect the size of the low-pressure area or the air flow gap between the heat exchange body 1 and the uniform wind arm 2. If the ratio is less than 1.1, it means that the maximum distance and the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 are close, which will cause the pressure in the low-pressure area to be not significantly reduced, so that the air near the low-pressure area cannot flow to the low-pressure area in large quantities, resulting in a decrease in uniform wind volume; if the ratio is greater than 2, it means that the maximum distance and the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 are quite different, which will cause the pressure reduction in the low-pressure area to be unable to match the air flow gap between the heat exchange body 1 and the uniform wind arm 2, which will also cause the air near the low-pressure area to be unable to flow to the low-pressure area in large quantities, resulting in a decrease in uniform wind volume.

[0100] Therefore, in the uniform wind mode, the ratio of the maximum distance to the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is in the range of 1.1-2.0, ensuring the uniform wind volume of the passive uniform wind. For example, in the uniform wind mode, the ratio of the maximum distance to the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9 or 2.0.

[0101] Optionally, in the uniform wind mode, the ratio of the maximum distance to the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is in the range of 1.4-1.6, ensuring a larger passive uniform wind volume.

[0102] In the uniform wind mode, the ratio of the maximum distance to the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is in the range of 1.4, 1.46, 1.5 or 1.6.

[0103] In the uniform wind mode, the maximum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is in the range of 33.6-58.4 mm.

[0104] In the uniform wind mode, if the maximum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is less than 33.6 mm, while ensuring that the ratio of the maximum distance to the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is within the range of 1.1-2.0, the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 will be too small, affecting the flow of sufficient air to the low-pressure area; if the maximum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is greater than 58.4 mm, the pressure in the low-pressure area will not be low enough, affecting the flow of sufficient air to the low-pressure area.

[0105] Therefore, in the uniform wind mode, the maximum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is in the range of 33.6-58.4 mm, for example, 33.6 mm, 38 mm, 41.6 mm, 45.6 mm, 50.6 mm or 58.4 mm, to ensure passive uniform air volume.

[0106] In the uniform wind mode, the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is in the range of 23-40 mm.

[0107] In the uniform wind mode, if the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is less than 23mm, the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 will be too small, affecting the flow of sufficient air to the low-pressure area; if the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is greater than 40mm, while ensuring that the ratio of the maximum distance to the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is within the range of 1.1-2.0, the maximum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 will be too large, causing the pressure in the low-pressure area to be not low enough, affecting the flow of sufficient air to the low-pressure area.

[0108] In the uniform wind mode, the minimum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is in the range of 23-40 mm, such as 23 mm, 26 mm, 31 mm, 35 mm or 40 mm, to ensure passive uniform air volume.

[0109] In the uniform wind mode, in the width direction of the uniform wind arm 2 (such as Fig.14 The upper surface of the wind-uniform arm protrudes toward the heat exchange body 1. The wind-uniform arm 2 is cut by the plane where the width direction of the wind-uniform arm 2 is located, and the cross section of the wind-uniform arm 2 is obtained as shown in FIG. Fig.14 As shown, the upper surface of the wind uniforming arm protrudes toward the heat exchange body 1.

[0110] In the uniform wind mode, a straight line passing through the highest point of the upper surface of the uniform wind arm 2 in the thickness direction of the uniform wind arm 2 divides the area near the uniform wind arm 2 into two areas, one forming a low-pressure area where the second air inlet and outlet 212 is located, and the other forming an area near the low-pressure area. The pressure in the area near the low-pressure area is greater than the pressure in the low-pressure area, and the active flow low-pressure area forms passive uniform wind.

[0111] In the uniform wind mode, in the width direction of the uniform wind arm 2, the upper surface of the uniform wind arm is in a shape with a high middle portion and low ends.

[0112] This shape ensures the pressure difference between the low-pressure zone and the area near the low-pressure zone, and makes the minimum distance between the uniform wind arm 2 and the heat exchange bottom wall 112 smaller, so that the air in the area near the low-pressure zone can flow into the low-pressure zone at a higher speed, so that more air in the area near the low-pressure zone can flow into the low-pressure zone.

[0113] like Fig.14 As shown, the upper surface of the wind uniforming arm includes a first surface segment 221 and a second surface segment 222, the second surface segment 222 is connected to the first surface segment 221, and the first surface segment 221 and the second surface segment 222 are arranged in sequence from the back to the front; wherein, in the width direction of the wind uniforming arm 2, the first surface segment 221 is an arc surface protruding toward the heat exchange body 1.

[0114] This arrangement enables the air in the vicinity of the low-pressure area to flow smoothly toward the low-pressure area along the curved surface, thereby reducing the wind resistance of the air flowing through the first surface segment 221 .

[0115] In the width direction of the wind uniforming arm 2 , the second surface segment 222 is a plane inclined downward from the back to the front or a curved surface convex toward the heat exchange body 1 .

[0116] This arrangement ensures that the area of ​​the low-pressure zone is large enough so that the air in the vicinity of the low-pressure zone, such as after the low-pressure zone, can be fully mixed with the heat exchange air.

[0117] In the width direction of the wind uniforming arm 2 , the length of the first surface segment 221 is smaller than the length of the second surface segment 222 .

[0118] This arrangement ensures that the area of ​​the low-pressure zone is large enough so that the air in the vicinity of the low-pressure zone, such as after the low-pressure zone, can be fully mixed with the heat exchange air.

[0119] In the uniform wind mode, the lowest point of the first surface segment 221 is higher than the lowest point of the second surface segment 222 or is flush with the lowest point of the second surface segment 222 .

[0120] In the uniform wind mode, the maximum distance between the upper surface of the uniform wind arm and the heat exchange bottom wall 112 is the distance between the lowest point of the second surface segment 222 and the heat exchange bottom wall 112, ensuring that the area of ​​the low-pressure zone is large enough so that the air in the vicinity of the low-pressure zone, such as the air behind the low-pressure zone, can be fully mixed with the heat exchange air.

[0121] In the uniform wind mode, the uniform wind arm 2 is arranged below the heat exchange body 1, and the uniform wind shell 21 includes a first uniform wind side wall 213 and a second uniform wind side wall 214. The first uniform wind side wall 213 is arranged in front of the second uniform wind side wall 214 and is arranged opposite to the second uniform wind side wall 214. The second air inlet and outlet 212 is arranged on the first uniform wind side wall 213.

[0122] Compared with the second air inlet and outlet 212 being arranged at the top of the wind uniforming arm 2 in the wind uniforming mode, the second air inlet and outlet 212 in the present application is arranged at the first wind uniforming side wall 213, which reduces the impact force of the indoor air flowing out of the second air inlet and outlet 212 on the heat exchange air, thereby minimizing the impact on the air supply distance of the heat exchange air, and can increase the action time of the indoor air flowing out of the second air inlet and outlet 212 and the heat exchange air, thereby enhancing the mixing effect of the indoor air and the heat exchange air.

[0123] In the uniform wind mode, Fig.10 As shown, the width directions of the first uniform wind side wall 213 and the second uniform wind side wall 214 are both in the up-down direction, and the length direction is parallel to the length direction of the heat exchange outlet 114. In other words, in the uniform wind mode, the plane where the first uniform wind side wall 213 and the second uniform wind side wall 214 are located is a vertical plane. The first uniform wind side wall 213 is located at the rear side of the front wall of the heat exchange outlet 114 and at the front side of the rear wall 1142 of the heat exchange outlet, and the second uniform wind side wall 214 is located at the rear side of the rear wall 1142 of the heat exchange outlet.

[0124] The wind uniformity shell 21 also includes a third wind uniformity side wall 215, which is connected between the first wind uniformity side wall 213 and the second wind uniformity side wall 214, and in the wind uniformity mode, the third wind uniformity side wall 215 is located at the bottom of the wind uniformity arm 2, and the first air inlet and outlet 211 is arranged on the third wind uniformity side wall 215.

[0125] The third wind uniforming side wall 215 forms the bottom wall of the wind uniforming arm 2 in the wind uniforming mode. Compared with setting the first air inlet and outlet 211 on the second wind uniforming side wall 214, the present application sets the first air inlet and outlet 211 on the third wind uniforming side wall 215, which can reduce the influence of the first air inlet and outlet 211 on passive wind uniformity and ensure the uniform air volume of passive wind uniformity.

[0126] like Fig.15 As shown, the wind uniformity component includes a centrifugal fan 6, which is arranged in the wind uniformity housing 21, and is used to introduce indoor air from the first air inlet and outlet 211 and blow it from the second air inlet and outlet 212 to the heat exchange outlet 114.

[0127] The centrifugal fan 6 rotates the rotor to make the air in the centrifugal direction be subjected to the centrifugal force to generate a high-speed rotating airflow, so that the indoor air can enter from the third uniform wind side wall 215 and be blown out from the first uniform wind side wall 213 .

[0128] The air uniforming housing 21 extends along the length direction of the heat exchange air outlet 114 . There are multiple centrifugal fans 6 , which are sequentially arranged along the length direction of the air uniforming housing 21 .

[0129] Under the action of the centrifugal fan 6, the indoor air enters the uniform wind arm 2 from the first air inlet and outlet 211 and blows toward the heat exchange outlet 114 from the second air inlet and outlet 212. This part of the indoor air forms active uniform wind. Fig.15 The curved arrow starting from the heat exchange outlet indicates the flow direction of the heat exchange air, the curved arrow flowing through the heat exchange body and the wind uniforming arm indicates the flow direction of the passive wind uniforming, and the straight arrow passing through the wind uniforming arm indicates the flow direction of the active wind uniforming. When the heat exchange outlet 114 and the second air inlet and outlet 212 blow out air, a low pressure area will be generated at the heat exchange outlet 114 and the second air inlet and outlet 212 respectively, so that the indoor air will be passively sucked into the low pressure area to form passive wind uniforming. Therefore, a centrifugal fan 6 is provided to form active wind uniforming. The formation of active wind uniforming can increase the low pressure area at the second air inlet and outlet 212, thereby increasing the air volume of passive wind uniforming.

[0130] like Fig.16 As shown, a plurality of centrifugal fans 6 are provided, and the plurality of centrifugal fans 6 are arranged in sequence along the length direction of the wind uniformity housing 21, so that the air volume of active wind uniformity can be increased, and the air volume of passive wind uniformity can also be increased.

[0131] The number of the centrifugal fans 6 is greater than two, and the second air inlet and outlet 212 are arranged corresponding to the centrifugal fans 6 .

[0132] The second air inlet and outlet 212 is arranged corresponding to the centrifugal fan 6 , which means that the orthographic projection of the centrifugal fan 6 on the second wind uniforming side wall 214 at least partially overlaps with the second air inlet and outlet 212 .

[0133] When the number of centrifugal fans 6 is greater than two, the second air inlet and outlet 212 can be divided into a plurality of second sub-air inlet and outlet 2121 areas, the number of the second sub-air inlet and outlet 2121 is equal to and corresponds to the number of centrifugal fans 6, and the first air inlet and outlet 211 is divided into a plurality of first sub-air inlets and outlets, the number of the first sub-air inlets and outlets is equal to and corresponds to the number of centrifugal fans 6. Each centrifugal fan 6 inhales indoor air from the corresponding first sub-air inlet and outlet, and blows it out from the corresponding second sub-air inlet and outlet 2121.

[0134] like Fig.16 As shown, the number of the centrifugal fans 6 is 5, and the number of the second sub-air inlet and outlet 2121 is 5.

[0135] like Fig.17As shown, the plurality of centrifugal fans 6 include a first centrifugal fan 61 and a second centrifugal fan 62. The first centrifugal fan 61 is disposed at one end of the wind uniformity housing 21 in the length direction; the second centrifugal fan 62 is disposed at the other end of the wind uniformity housing 21 in the length direction, and the second air inlet and outlet 212 is staggered with the first centrifugal fan 61 and the second centrifugal fan 62, and is disposed in an area between the first centrifugal fan 61 and the second centrifugal fan 62 on the first wind uniformity side wall 213.

[0136] The second air inlet and outlet 212 and the first centrifugal fan 61 and the second centrifugal fan 62 are staggered, which means that the orthographic projections of the first centrifugal fan 61 and the second centrifugal fan 62 on the first uniform wind side wall 213 do not overlap with the second air inlet and outlet 212. The second air inlet and outlet 212 is arranged in the area between the first centrifugal fan 61 and the second centrifugal fan 62 on the first uniform wind side wall 213, so that the air outlets of the first centrifugal fan 61 and the second centrifugal fan 62 can both flow out from the second air inlet and outlet 212, thereby reducing the setting area of ​​the second air inlet and outlet 212, and reducing the flow rate of the indoor air flowing out of the second air inlet and outlet 212, increasing the mixing time of the indoor air flowing out of the second air inlet and outlet 212 and the heat exchange air, and improving the mixing effect.

[0137] The first air inlet and outlet 211 are disposed correspondingly to the first centrifugal fan 61 and the second centrifugal fan 62 .

[0138] The first air inlet and outlet 211 is divided into two first sub-inlet and outlets, which correspond to the first centrifugal fan 61 and the second centrifugal fan 62 respectively. The first centrifugal fan 61 inhales indoor air from one of the first sub-inlet and outlet and blows it toward the second sub-inlet and outlet 2121. The second centrifugal fan 62 inhales indoor air from the other first sub-inlet and outlet and blows it toward the second sub-inlet and outlet 2121.

[0139] There are two centrifugal fans 6 , namely a first centrifugal fan 61 and a second centrifugal fan 62 . This solution can reduce the number of centrifugal fans 6 and reduce the cost of the wind uniforming arm 2 .

[0140] Embodiment 2:

[0141] The difference from the first embodiment is that Figures 18 to 21 As shown, the wind uniforming arm 2 is provided with a through hole 23 running through it. In the wind uniforming mode, the wind uniforming arm 2 is arranged below the heat exchange body 1 and the first end 231 of the through hole faces the heat exchange air outlet 114, and is used to introduce indoor air from the second end 232 of the through hole and flow to the first end 231 of the through hole to mix with the heat exchange air flowing out of the heat exchange air outlet 114.

[0142] When the heat exchange outlet 114 blows out air, a low pressure area will be generated at the heat exchange outlet 114. In the uniform wind mode, the uniform wind arm 2 is arranged below the heat exchange body 1, and a part of the indoor air is sucked into the low pressure area from between the uniform wind arm 2 and the heat exchange body 1, and a part of the indoor air flows to the low pressure area through the second end 232 of the through hole and the first end 231 of the through hole. Both parts of the indoor air form passive uniform wind, which increases the uniform wind volume of the passive uniform wind. When the uniform wind volume of the passive uniform wind is large enough, there is no need to set the uniform wind component in the related art, thereby avoiding the noise problem of the uniform wind component and reducing the energy consumption of the air conditioner.

[0143] The through hole 23 extends in a thickness direction or a width direction of the wind uniforming arm 2 .

[0144] In the uniform wind mode, the thickness of the uniform wind arm 2 is along the up-down direction, and the width of the uniform wind arm 2 is along the front-back direction.

[0145] The extension direction of the through hole 23 extends along the thickness direction or the width direction of the wind uniforming arm 2 , so that the airflow flowing out of the first end 231 of the through hole can be directed toward the heat exchange air outlet 114 .

[0146] The extending direction of the through hole 23 may not be along the thickness direction or the width direction of the wind uniforming arm 2. For example, in the wind uniforming position, the through hole 23 is inclined upward from the back to the front.

[0147] The extending direction of the through hole 23 may not be a straight line, but may include a curve and a straight line, or a broken line.

[0148] The cross section of the through hole 23 is circular, and the inner diameter of the through hole 23 is in the range of 3 mm to 6 mm.

[0149] The inner diameter of the through hole 23 is less than 3 mm, resulting in the inner diameter of the through hole 23 being too small, and the wind resistance of the indoor air flowing in the through hole 23 is large, reducing the amount of indoor air passing through the through hole 23; the inner diameter of the through hole 23 is greater than 6 mm, resulting in the size of the through hole 23 being too large, and the structural strength of the wind uniforming arm 2 cannot be guaranteed.

[0150] Therefore, the inner diameter range of the through hole 23 is 3 mm-6 mm, for example, 3 mm, 4 mm, 5 mm or 6 mm, so as to increase the amount of indoor air passing through the through hole 23 while ensuring the structural strength of the wind uniforming arm 2.

[0151] The cross section of the through hole 23 may be in various shapes, such as an ellipse or a polygon.

[0152] There are multiple through holes 23, which are divided into multiple groups. Each group of through holes 23 includes multiple through holes 23. The multiple through holes 23 in each group are arranged in sequence along the length direction of the wind uniforming arm 2, and the multiple groups of through holes 23 are arranged in sequence along the width direction of the wind uniforming arm 2.

[0153] Multiple through holes 23 in each group are arranged in sequence along the length direction of the wind uniforming arm 2, so that the passive uniform air volume near each position in the length direction of the wind uniforming arm 2 is roughly equal. Multiple groups of through holes 23 are arranged in sequence along the width direction of the wind uniforming arm 2, so that the passive uniform air volume near each position in the width direction of the wind uniforming arm 2 is roughly equal.

[0154] The plurality of groups of through holes 23 are arranged correspondingly or staggered.

[0155] The corresponding arrangement of multiple groups of through holes 23 means that among two adjacent groups of through holes 23, the orthographic projection of one group of through holes 23 on the plane where the other group of through holes 23 is located at least partially overlaps with the other group of through holes 23, thereby improving the regularity of the multiple through holes 23 and avoiding mutual interference of airflows flowing out of the multiple through holes 23.

[0156] like Fig.21 As shown, multiple through holes in each group are arranged in sequence from left to right (along the length direction of the wind uniforming arm), and multiple groups of through holes are arranged in sequence from top to bottom (along the width direction of the wind uniforming arm).

[0157] The working position of the wind uniforming arm 2 includes the wind uniforming position. In the wind uniforming mode, the wind uniforming arm 2 is in the wind uniforming position.

[0158] The staggered arrangement of multiple groups of through holes 23 means that the orthographic projection of one group of through holes 23 on the plane where another group of through holes 23 is located does not overlap with the other group of through holes 23. When the wind uniforming arm 2 is in the closed position of closing the heat exchange air outlet 114, the heat exchange air flowing out of the heat exchange air outlet 114 can flow out through multiple through holes 23. The staggered arrangement of multiple through holes 23 can more fully disperse the heat exchange air, so that the user does not feel the cold wind blowing directly, forming a breeze mode, such as Fig.19 Improve user comfort.

[0159] In the closed position, the length direction (extension direction) of the through hole 23 is not parallel to the outlet direction of the heat exchange air.

[0160] In the breeze mode, after the heat exchange air flows out through the heat exchange air outlet 114, the direction needs to be deflected before it can flow into the through hole 23, which further avoids direct blowing of cold air.

[0161] In the closed position, the through hole 23 is inclined downward along the outlet direction of the heat exchange air.

[0162] Embodiment three:

[0163] The difference from the first and second embodiments is that Figure 22 to Figure 25As shown, the wind uniforming arm 2 includes a wind uniforming body and a grille 25, and the wind uniforming body includes a wind uniforming housing 21. The wind uniforming body is provided with a vent 24. In the closed position, the wind uniforming arm 2 is arranged at the heat exchange air outlet 114, and the first end 241 of the vent is connected to the heat exchange air outlet 114. The heat exchange air flowing out of the heat exchange air outlet 114 enters through the first end 241 of the vent and flows out from the second end 242 of the vent.

[0164] In the closed position, the heat exchange air flows in through the first end 241 of the ventilation hole and flows out from the second end 242 of the ventilation hole. The grille 25 is arranged at the second end and protrudes outwardly from the wind uniformity body. The grille 25 can disperse the heat exchange air flowing out from the second end 242 of the ventilation hole to avoid direct blowing of the heat exchange air, thereby realizing a breeze mode. Fig.23 shown.

[0165] There is a non-zero angle between the grille 25 and the ventilation hole 24 in the length direction, so that the air flowing out of the ventilation hole 24 can change its flow direction after passing through the grille 25, without affecting the function of the wind uniforming arm 2 in the working position, so that the air outlet direction in the breeze mode meets the user's needs.

[0166] In the closed position, the grille 25 extends in a horizontal direction or is inclined upward in the air outlet direction.

[0167] The grille 25 divides the heat exchange air flowing out from the second end 242 of the ventilation hole into multiple small air flows, so that the air flow is blown horizontally or upwards, so that the user does not feel the direct blowing of cold air, thereby improving the user's comfort.

[0168] In the closed position, the angle between the grille 25 and the horizontal direction ranges from 0° to 10°, such as 0°, 2°, 4°, 6°, 8° or 10°.

[0169] In the closed position, if the angle between the grille 25 and the horizontal direction is less than 0°, the heat exchange air will blow downward after passing through the grille 25, causing cold air to blow directly in the cooling mode; in the closed position, if the angle between the grille 25 and the horizontal direction is greater than 10°, the heat exchange air will blow upward at a greater amplitude and it will take a longer time to reach the ground, reducing the cooling speed.

[0170] The grille 25 is fixedly connected to the air uniformity body; or, the grille 25 is rotatably connected to the air uniformity body to adjust the angle between the grille 25 and the air uniformity body.

[0171] The grille 25 is fixedly connected to the air uniforming body, and the grille 25 and the air uniforming body are an integrated structure, or the grille 25 and the air uniforming body are a split structure connected, in which case screw connection or clamping can be used. The way in which the grille 25 is fixedly connected to the air uniforming body makes the structure of the air uniforming arm 2 simple.

[0172] When the grille 25 is rotationally connected to the air leveling body, the grille 25 can rotate relative to the air leveling body to change the angle between the grille 25 and the air leveling body, thereby changing the flow direction of the heat exchange air flowing out through the grille 25. When the grille 25 is rotationally connected to the air leveling body, the grille 25 can rotate relative to the air leveling body between a first position and a second position. In the first position, the angle between the grille 25 and the horizontal plane is 0°, and in the second position, the angle between the grille 25 and the horizontal plane is 10°. The way in which the grille 25 is rotationally connected to the air leveling body allows the user to automatically adjust the position of the grille 25 according to their own needs or the air conditioner can automatically adjust the position of the grille 25 according to environmental parameters, etc., to achieve a variety of air supply directions.

[0173] There are multiple ventilation holes 24 , each of which extends along the length direction of the wind uniforming arm 2 , and the multiple ventilation holes 24 are arranged in sequence along the width direction of the wind uniforming arm 2 .

[0174] There are multiple grilles 25, which are equal to and correspond to the number of ventilation holes 24. Each grille 25 extends along the length direction of the air distribution body, and multiple grilles 25 are sequentially arranged along the width direction of the air distribution body.

[0175] In this way, the heat exchange air flowing out from different positions of the wind uniforming body can be blown out through the corresponding grilles 25, so that the overall airflow flow direction is roughly the same, and the airflows flowing out from different grilles 25 will not interfere with each other.

[0176] In the closed position, the multiple grilles 25 have the same inclination degree, which reduces the mutual interference between the airflows flowing out through different grilles 25 .

[0177] like Fig. 22 As shown, the height L3 of the grille 25 protruding from the air uniforming body ranges from 5 mm to 10 mm, for example, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm.

[0178] When the height of the grille 25 protruding from the air uniforming body is less than 5 mm, the effect of the grille 25 on extending the air supply distance and changing the air flow direction will not be obvious; when the height of the grille 25 protruding from the air uniforming body is greater than 10 mm, the grille 25 will affect the landing of the air flow and reduce the cooling speed.

[0179] In the closed position, the angle between the length direction of the ventilation hole 24 and the air outlet direction of the heat exchange air outlet 114 is less than or equal to 30°, for example, 0°, 10°, 20° or 30°.

[0180] The angle between the length direction of the ventilation hole 24 and the air outlet direction of the heat exchange air outlet 114 is greater than 30°, resulting in a larger angle between the ventilation hole 24 and the air outlet direction of the heat exchange air outlet 114. In this way, the heat exchange air flowing out of the heat exchange air outlet 114 needs to be deflected at a large angle before it can flow into the ventilation hole 24, which will cause a large energy loss of the heat exchange air.

[0181] In the direction from the rear to the front, the ventilation holes 24 are inclined downward.

[0182] The heat exchange air flowing out of the air duct 122 is blown forward and downward as a whole. Along the direction from back to front, the ventilation holes 24 are tilted downward, so that the extension direction of the ventilation holes 24 is roughly consistent with the flow direction of the heat exchange air flowing out of the air duct 122, thereby reducing the energy loss of the heat exchange air entering the ventilation holes 24 from the air duct 122.

[0183] The ventilation holes 24 penetrate through two opposite side walls of the wind uniforming body.

[0184] The wind uniformity housing 21 further includes a fourth wind uniformity side wall 216, which is arranged opposite to the third wind uniformity side wall 215. The third wind uniformity side wall 215 and the fourth wind uniformity side wall 216 are arranged in sequence along the outflow direction of the heat exchange air. The ventilation hole 24 passes through the third wind uniformity side wall 215 and the fourth wind uniformity side wall 216. The first end 241 of the ventilation hole is arranged on the fourth wind uniformity side wall 216, and the second end 242 of the ventilation hole is arranged on the third wind uniformity side wall 215.

[0185] The ventilation holes 24 penetrate the two opposite side walls of the wind uniforming body, which can reduce the wind resistance of the airflow flowing through the ventilation holes 24, so that the airflow entering the first end 241 of the ventilation hole can smoothly flow out from the second end 242 of the ventilation hole.
