Thus, the features defined with "first", "second" may explicitly or implicitly include at least one such feature. Additionally, the meaning of "and / or" appearing throughout the text is that it includes three parallel scenarios. Taking "A and / or B" as an example, it includes scenario A, or scenario B, or the scenario where both A and B are satisfied simultaneously.

[0047] The present invention provides a floor-standing air conditioner indoor unit.

[0048] Please refer to Figures 1 to 3 , the present invention provides a floor-standing air conditioner indoor unit 100, which includes a housing 110 and a fresh air module 130. A fresh air inlet 112 is provided on the back of the housing 110, and an air outlet panel 113 is provided on the front side of the housing 110. An air outlet cavity 118 is formed on one side of the air outlet panel 113 close to the fresh air inlet 112, and the air in the air outlet cavity 118 can be blown out through the air outlet panel 113. The fresh air module 130 is disposed in the housing 110, and the fresh air module 130 has a fresh air duct 131, and the fresh air duct 131 communicates the fresh air inlet 112 with the air outlet cavity 118.

[0049] In the embodiments of the present invention, the housing 110 extends integrally in the up and down direction. The cross-sectional shape of the housing 110 can be circular, elliptical, rectangular, etc., which can be selected according to actual usage requirements and will not be specifically limited herein. The housing 110 can be integrally formed, and of course, the housing 110 can also be a split structure. For example, the housing 110 includes a back panel and a front panel, the fresh air inlet 112 is opened on the back panel, and the air outlet panel 113 is disposed on the front panel. Among them, the air outlet panel 113 can be integrally formed on the front panel, but is not limited thereto. It can be understood that the front panel can be integrally formed or a split structure. For example, the front panel includes an upper panel and a lower panel, and the air outlet panel 113 can be disposed on the upper panel or the lower panel. It is worth mentioning that if the air outlet panel 113 is disposed at the upper end of the front panel, that is, on the upper panel, the fresh air blown out through the air outlet panel 113 will not be blocked by sofas or tables in the room, thus not affecting the fresh air ventilation efficiency. Similarly, the back panel can be integrally formed or a split structure. For example, the back panel includes an upper back panel and a lower back panel, and the fresh air inlet 112 can be disposed on the upper back panel or the lower back panel.

[0050] The air outlet panel 113 can be arranged in a flat plate shape. Of course, in order to increase the air outlet range, the air outlet panel 113 can also be arranged in an arc plate shape, without specific limitation. At least one fresh air outlet 114 is provided on the air outlet panel 113, so that the air outlet area of the fresh air can be increased, the air supply range of the fresh air can be increased, the fresh air can be diffused throughout the room, with good uniformity, fast air change speed, and at the same time, the noise can be reduced and the power can be decreased. There can be various structures for the air outlet panel 113. For example, the air outlet panel 113 can be a perforated plate or a grille plate, but it is not limited thereto, and will be introduced in detail below. An air outlet cavity 118 is formed on one side of the air outlet panel 113 close to the fresh air inlet 114, that is, an air outlet cavity 118 is formed on the air inlet side of the air outlet panel 113. The fresh air duct 131 of the fresh air module 130 is communicated with the air outlet cavity 118, so that the fresh air entering the fresh air duct 131 can further enter the air outlet cavity 118, and then is blown out through the air outlet panel 113. Among them, the fresh air module 130 can be arranged on the side of the air outlet cavity 118 away from the air outlet panel 113, or can be arranged below the air outlet cavity 118, without specific limitation here.

[0051] The floor-standing air conditioner indoor unit 100 of the present invention is provided with a fresh air inlet 114 on the back of the housing 110 and an air outlet panel 113 on the front side of the housing 110. An air outlet cavity 118 is formed on one side of the air outlet panel 113 close to the fresh air inlet 114. The air outlet cavity 118 is communicated with the fresh air duct 131 of the fresh air module 130, so that the fresh air entering the fresh air duct 131 can further flow into the air outlet cavity 118 and is blown out through the air outlet panel 113. In this way, the air outlet area of the fresh air is increased, the air supply range of the fresh air is increased, and the fresh air ventilation efficiency of the floor-standing air conditioner indoor unit 100 is improved, so that the user can feel the freshness of the fresh air.

[0052] In order to achieve the air outlet effect of a gentle breeze or no wind for the fresh air blown out through the air outlet panel 113, in an embodiment, the floor-standing air conditioner indoor unit 100 further includes a swirl module 150. The swirl module 150 is installed on the side of the air outlet panel 113 close to the air outlet cavity 118, that is, the swirl module 150 is located in the air outlet cavity 118. The swirl module 150 is suitable for allowing air flow to pass through and diffusing the air flow passing through it. After the air flow passes through the swirl module 150, the original flow direction is changed and can flow into different flow channels, so as to realize the diffusion flow of the air flow and achieve the air outlet effect of a gentle breeze or no wind. The swirl module 150 can include a diffuser grille structure, a swirl wind wheel 155 structure, a microporous plate structure, etc., as long as it can realize the diffusion of the air flow passing through it.

[0053] Please refer to Figure 1, at least one fresh air outlet 114 is formed on the air outlet panel 113, and the swirl module 150 includes at least one swirl air wheel 155, and at least one of the swirl air wheels 155 is correspondingly installed at at least one of the fresh air outlets 114. The swirl air wheel 155 can be fixedly installed at the fresh air outlet 114 or rotatably installed at the fresh air outlet 114. It can be understood that the swirl air wheel 155 means that the blades of the swirl air wheel 155 are curved or arranged at an angle with the air inlet direction, so that the air flow passing through the swirl air wheel 155 forms a swirl, or the air inlet direction is inconsistent with the air outlet direction. In this way, the air flow of the air outlet can be effectively broken up and agitated, making the air outlet softer, with small air resistance and air loss, and the air volume without wind feeling can be effectively improved. Specifically, the swirl air wheel 155 is an axial flow air wheel. Specifically, the swirl air wheel 155 is an axial flow air wheel. In some embodiments, the swirl air wheel 155 can also be a double-layer blade structure, where one layer of blades is a stationary blade and the other layer of blades is a rotating blade. When the outer rotating blade rotates, the size of the pure area is continuously changed, so that the size of the fresh air outlet air flow can be adjusted, and the fresh air supply angle is increased.

[0054] Please refer to Figure 8 , in some embodiments, the swirl module 150 further includes a mounting plate 153, the mounting plate 153 is mounted on the surface of the air outlet panel 113 close to the air outlet cavity 118, and a mounting through hole 154 corresponding to the fresh air outlet 114 is provided on the mounting plate 153, and the swirl air wheel 155 is correspondingly installed at the mounting through hole 154.

[0055] Please refer to Figure 8 , in this embodiment, the swirl air wheel 155 includes a first air wheel 156 and a second air wheel 157, the first air wheel 156 is fixedly connected to the mounting through hole 154; the second air wheel 157 is rotatably installed at the mounting through hole 154, so that the blades of the second air wheel 157 and the blades of the first air wheel 156 are arranged in a stacked or staggered manner in the air passing direction of the mounting through hole 154. In order to make the air flow blown out from the mounting through hole 154 all be the air flow broken up and blown out by the first air wheel 156 and the second air wheel 157, it is preferably that the mounting through hole 154 is circular and adapted to the sizes of the first air wheel 156 and the second air wheel 157.

[0056] The first air wheel 156 is fixedly installed at the mounting through hole 154 of the mounting plate 153, then the first air wheel 156 can be integrally formed with the mounting plate 153 or fixed on the mounting plate 153 by means of welding, bonding, pressing, etc. The rotation of the second air wheel 157 can be specifically driven by a driving motor, or a rolling bearing and other structures can be provided so that the second air wheel 157 can automatically rotate under the drive of the air flow.

[0057] It should be noted that both the first wind wheel 156 and the second wind wheel 157 are installed at the installation through hole 154, and they are arranged in a stacked or staggered manner in the air passing direction of the installation through hole 154, so that the first wind wheel 156 and the second wind wheel 157 are arranged in sequence in the air passing direction of the installation through hole 154. The installation through hole 154 plays a role in guiding and leading the air flow. The number and size of the blades of the first wind wheel 156 can be the same as or different from those of the second wind wheel 157. The first wind wheel 156 is fixed at the installation through hole 154, and the second wind wheel 157 is rotatably installed at the installation through hole 154. By continuously rotating the second wind wheel 157, on the one hand, it drives the air flow to blow out from the installation through hole 154, reduces the wind resistance and wind loss, effectively improves the air volume, and can flexibly control the strength of the blown air flow. On the other hand, the blades of the second wind wheel 157 overlap or are misaligned with the blades of the first wind wheel 156, so that the air flow passing through the installation through hole 154 is continuously cut, scattered, shunted and stirred by the first wind wheel 156 and the second wind wheel 157, making the blown air softer, greatly improving the no-wind feeling effect, and making the divergence direction of the air flow controllable and adjustable.

[0058] Please refer to again Figure 2 and Figure 3 , without loss of generality, the housing 110 is provided with an indoor air inlet 111, a main air outlet 115 and a heat exchange air duct connecting the indoor air inlet 111 and the main air outlet 115. In an embodiment, the floor-standing air conditioner indoor unit 100 further includes a first valve assembly 120, and the first valve assembly 120 is used to conduct or cut off the air outlet cavity 118 and the heat exchange air duct.

[0059] In this embodiment, the first valve assembly 120 has a conducting position and a cutting-off position. When the valve assembly is in the conducting position, the air outlet cavity 118 is in communication with the heat exchange air duct, so that the air flow in the heat exchange air duct can flow into the air outlet cavity 118 and mix and exchange heat with the fresh air in the air outlet cavity 118, so that the temperature of the fresh air blown into the room through the air outlet panel 113 is not too cold or too hot, effectively solving the problem of user discomfort caused by the too cold outdoor fresh air in winter and the too hot outdoor fresh air in summer. In addition, by fully mixing the air flow in the heat exchange air duct with the fresh air, the blowing speed and distance of the fresh air are effectively improved, so that the fresh air quickly fills the room, improving the fresh air ventilation efficiency. When the first valve assembly 120 is in the cutting-off position, the air outlet cavity 118 is not in communication with the heat exchange air duct, so that the air flow in the heat exchange air duct is blown out through the main air outlet 115, and rapid heating or cooling can be achieved.

[0060] Specifically, the first valve assembly 120 includes a valve and a driving device, and the driving device is connected to the valve to drive the valve to move to connect or block the air outlet cavity 118 and the heat exchange air duct. The valve and the housing 110 can be slidably connected or rotatably connected, that is, the valve can switch between a connecting position and a blocking position by sliding or rotating.

[0061] In one embodiment, the main air outlet 115 includes a left air outlet 116 and a right air outlet 117 located on opposite sides of the air outlet panel 113, and the heat exchange air duct includes a left air duct connected to the left air outlet 116, and a right air duct connected to the right air outlet 117. Here, by blowing the fresh air sucked in by the fresh air module 130 out of the air outlet panel 113, the airflow blown out of the left and right air ducts is effectively utilized to fully mix the fresh air twice outside the air outlet panel 113, so as to achieve a longer air supply distance, effectively improve the mixing speed of the fresh air and the indoor air, and enable the fresh air to quickly fill the room.

[0062] For ease of description, the valve includes a left valve 121 and a right valve 122. The left valve 121 is used to connect or block the air outlet chamber 118 and the left air duct, and the right valve 122 is used to connect or block the air outlet chamber 118 and the right air duct. In this embodiment, the left valve 121 is rotatably connected to the housing 110, and the right valve 122 is rotatably connected to the housing 110. Both the left valve 121 and the right valve 122 have an axis extending in the up-down direction. In order to better drive the left valve 121 and the right valve 122 to rotate, the driving device further includes a first driving device and a second driving device, wherein the first driving device is connected to the left valve 121 to drive the left valve 121 to rotate around an axis extending in the up-down direction to connect or block the air outlet cavity 118 and the left air duct; the second driving device is connected to the right valve 122 to drive the right valve 122 to rotate around an axis extending in the up-down direction to connect or block the air outlet cavity 118 and the right air duct. Specifically, the first driving device and the second driving device are both driving motors, but are not limited thereto.

[0063] See also Figure 3 , Figure 4 and Figure 5 The floor-standing air-conditioning indoor unit 100 also includes a partition 119 spaced apart from the air outlet panel 113. The partition 119 is disposed between the left air duct and the right air duct, and connects the left air duct and the right air duct. The partition 119, the left valve 121, the right valve 122 and the air outlet panel 113 together enclose the air outlet cavity 118.

[0064] Specifically, the floor-standing air conditioner indoor unit 100 further includes a left volute assembly and a right volute assembly. The left volute assembly includes a left volute and a left volute tongue, and the left volute and the left volute tongue enclose to form the left air duct. The right volute assembly includes a right volute and a right volute tongue, and the right volute and the right volute tongue enclose to form the right air duct. Wherein, cross-flow fans 160 are respectively arranged in the left air duct and the right air duct. Here, it should be noted that when the left valve 121 is in the cut-off position, the free end of the left valve 121 abuts against the end of the left volute. Similarly, when the right valve 122 is in the cut-off position, the free end of the right valve 122 abuts against the end of the right volute. It can be understood that in other embodiments, the left valve 121 can also be rotatably connected to the left volute, and the right valve 122 is rotatably connected to the right volute.

[0065] Please refer to Figure 3 , in this embodiment, a left switch 171 is provided at the left air outlet 116 for opening or closing the left air outlet 116, and a right switch door 172 is arranged at the right air outlet 117 for opening or closing the right air outlet 117. It can be understood that when the left switch door 171 opens the left air outlet 116, the gas in the left air duct can be blown out from the left air outlet 116; when the right switch door 172 opens the right air duct, the gas in the right air duct can be blown out from the right air outlet 117. It can be understood that the floor-standing air conditioner indoor unit 100 further includes two switch door driving devices, and the two switch door driving devices respectively drive the left switch door 171 and the right switch door 172 to move. The specific structure of the switch door driving device is not limited, as long as it can drive the left and right switch doors to open or close.

[0066] In order to better achieve the effect of high-efficiency windless air output, rotatable air guide strips 170 can be respectively arranged at the left air outlet 116 and the right air outlet 117 (as Figure 3 shown), and a plurality of air dispersion holes are formed in the air guide strips. When the air guide strip 170 rotates to be perpendicular to the air flow direction (as Figure 10 shown), the air flow can be blown out through the air dispersion holes on the air guide strip 170, so as to achieve the effect of windless air output. When the air guide strip 170 rotates to be parallel to the air flow direction (as Figure 11 shown), the air flow can be blown out through the left and right air outlets, so as to achieve the effect of rapid cooling or heating.

[0067] Please refer to Figure 2 , Figure 6 and Figure 7, in one embodiment, the floor-standing air conditioner indoor unit 100 further includes a second valve assembly 140, which is installed in the fresh air duct 131 or the air outlet cavity 118 to conduct or cut off the air outlet cavity 118 and the fresh air duct 131. By providing the second valve assembly 140, fresh air can be selectively mixed with swirl air supply or separately supplied with swirl air, so that swirl air supply of fresh air can be achieved while not affecting the draft-free air supply at the upper part of the air conditioner.

[0068] Specifically, the fresh air duct 131 is located below the air outlet cavity 118. The fresh air inlet 112 is provided on the lower back panel, and a fresh air pipe is installed at the fresh air inlet 112. The fresh air pipe is communicated with the outside, and the air outlet panel 113 is provided on the upper panel. In this way, outdoor fresh air is introduced into the fresh air duct 131 from the fresh air pipe, flows into the air outlet cavity 118, and finally blows into the room through the air outlet panel 113, thereby changing the indoor air quality.

[0069] In some embodiments, the fresh air duct 131 includes an air inlet duct 132 and an air outlet duct 133 that are communicated with each other. The air inlet duct 132 is communicated with the fresh air inlet 112, and the air outlet duct 133 is communicated with the air outlet cavity 118. The second valve assembly 140 is installed in the air outlet duct 133 to conduct or cut off the air outlet duct 133 and the air outlet cavity 118. Of course, in other embodiments, the second valve assembly 140 may also be provided at one end of the air outlet cavity 118 close to the air outlet duct 133.

[0070] In this embodiment, an air passing opening 136 is provided at the upper end of the air outlet duct 133 and opens forward. The swirl module 150 includes a first swirl part 151 corresponding to the air outlet cavity 118 and a second swirl part 152 corresponding to the air passing opening 136. The second swirl part 152 is located below the first swirl part 151. The air outlet panel 113 includes a first air outlet part corresponding to the first swirl part 151 and a second air outlet part corresponding to the second swirl part 152. Here, it should be noted that the air passing opening 136 is located below the air outlet cavity 118, corresponding to the air outlet cavity 118 means directly facing the air outlet cavity 118, and corresponding to the air passing opening 136 means directly facing the air passing opening 136.

[0071] When the second valve assembly 140 conducts the air outlet duct 133 and the air outlet cavity 118, part of the air flow blown out from the air passing opening 136 of the air outlet duct 133 can be diffused out through the second swirling part 152, and the other part can be diffused out through the first swirling part 151. When the second valve assembly 140 cuts off the air outlet duct 133 and the air outlet cavity 118, all the air flow blown out from the air passing opening 136 of the air outlet duct 133 is diffused out through the second swirling part 152.

[0072] In this embodiment, the second valve assembly 140 includes a switching valve 141 and a third driving device 142.
