Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an indoor air conditioning unit and an air conditioner. Background Technology

[0002] Currently, cabinet air conditioners typically have two air outlets at different heights. When cooling, cold air flows out from the higher air outlet, and when heating, hot air flows out from the lower air outlet to achieve a warming effect on the feet. However, because the fan inside the cabinet air conditioner is fixed, the fan outlet can only consistently face one air outlet. When switching to another air outlet, the airflow blown out by the fan will directly hit the air guide plate because the air outlet that the fan was facing is closed, resulting in insufficient airflow and difficulty in simultaneously achieving both cooling and heating effects.

[0003] In related technologies, a rotatable air guide plate is installed at the outlet of the fan. By rotating the air guide plate, the airflow direction of the fan can be changed, thereby guiding the airflow blown by the fan to another air outlet. However, for this method, since the air guide plate will block part of the fan outlet, the air volume of the fan will be reduced, and the air outlet effect is not ideal. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an indoor air conditioning unit that can change the air supply direction of the fan, taking into account both cooling and heating effects, achieving a comfortable cooling and heating effect, and with minimal air volume loss when switching between cooling and heating.

[0005] This utility model also proposes an air conditioner having the above-mentioned indoor air conditioning unit.

[0006] An indoor air conditioning unit according to a first aspect embodiment of the present invention includes:

[0007] The housing has a cavity, and a first air inlet communicating with the cavity is provided on one side of the housing, and a first air outlet and a second air outlet communicating with the cavity are provided on the other side of the housing, with the first air outlet and the second air outlet arranged sequentially from top to bottom;

[0008] A fan is rotatably mounted inside the cavity;

[0009] A first driving device is used to drive the fan to rotate so that the fan delivers air toward the first air outlet or the second air outlet.

[0010] The air conditioner indoor unit according to the first aspect of the present invention has at least the following beneficial effects: the air conditioner indoor unit can drive the fan to rotate through the first driving device, thereby changing the air delivery direction of the fan. For example, when cooling, the first driving device can be controlled to drive the fan to deliver air towards the first air outlet. When heating, the first driving device can be controlled to drive the fan to deliver air towards the first air outlet or the second air outlet, thereby changing the air delivery direction of the fan. This facilitates the smooth flow of air from the fan out of the specific air outlet, and can simultaneously take into account the air delivery effect of cooling and heating, achieving a comfortable cooling and heating effect. Furthermore, since there are no obstructions at the air outlet of the fan, the impact on the air volume of the fan is small, the air delivery effect is better, and the air volume loss during the switching between cooling and heating is small.

[0011] According to some embodiments of the present invention, a first air guide component is provided at the first air outlet, and a second air guide component is provided at the second air outlet;

[0012] When the indoor unit of the air conditioner is configured to be in cooling mode, the first air guide component opens the first air outlet and the second air guide component closes the second air outlet, and the first drive device drives the fan to rotate so that the fan blows air toward the first air outlet.

[0013] or:

[0014] When in heating mode, the first air guide component closes the first air outlet, and the second air guide component opens the second air outlet. The first drive device drives the fan to rotate, so that the fan blows air toward the second air outlet.

[0015] According to some embodiments of the present invention, there are two fans, which are arranged at intervals along the height direction of the housing. There are two first driving devices, which drive the two fans to rotate respectively. The two fans are arranged corresponding to the first air outlet and the second air outlet respectively.

[0016] According to some embodiments of the present invention, the inner wall of the cavity defines an air guide channel arranged along the height direction of the housing. The air guide channel connects the first air outlet and the second air outlet. The air guide channel has an opening. The fan includes a volute and a fan wheel.

The heat exchanger is shrouded on the side of the fan away from the air guide channel and covers the second air inlet.

[0018] According to some embodiments of the present invention, the outer wall of the volute is provided with a sealing part, which is used to seal the gap between the volute and the opening.

[0019] According to some embodiments of the present invention, the sealing part includes a first sealing plate and a second sealing plate. The first sealing plate is located above the second sealing plate. When the air outlet is facing the first air outlet, the first sealing plate seals the gap between the lower side of the volute and the opening. When the air outlet is facing the second air outlet, the second sealing plate seals the gap between the upper side of the volute and the opening.

[0020] According to some embodiments of the present invention, the indoor unit of the air conditioner further includes a rotating shaft, a first gear and a second gear. The inner wall of the housing is provided with a shaft hole. The rotating shaft is rotatably connected to the shaft hole. The rotating shaft is fixedly connected to the fan. The first gear is fixedly connected to the rotating shaft. The second gear is fixedly connected to the output end of the first drive device. The second gear meshes with the first gear.

[0021] According to some embodiments of this utility model, an air guide assembly is provided at the first air outlet or the second air outlet. The air guide assembly includes a swing arm, two air guide plates, a second driving device, a third driving device, and a fourth driving device. The swing arm is rotatably connected to the housing, and the two air guide plates are respectively rotatably connected to the swing arm. The second driving device is used to drive the swing arm to rotate relative to the housing. The third driving device and the fourth driving device respectively drive the two air guide plates to rotate relative to the swing arm, so that the two air guide plates are at an angle to each other or parallel to each other.

[0022] An air conditioner according to a second aspect of the present invention includes an indoor unit of the air conditioner according to the first aspect of the present invention.

[0023] The air conditioner according to the second aspect of the present utility model, since it includes the indoor unit of the air conditioner according to the first aspect embodiment, has at least the above-mentioned beneficial effects, which will not be repeated here.

[0024] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0045] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0046] Currently, traditional floor-standing air conditioners only have a single air outlet, which is quite high off the ground. This results in poor heating performance, difficulty in pushing hot air down to the ground, poor foot warmth, and an inability to achieve optimal cooling and heating simultaneously. Therefore, some floor-standing air conditioners typically have two air outlets at different heights on their casing. During cooling, cold air flows from the higher outlet, while during heating, to achieve foot warmth, hot air flows from the lower outlet. However, because the internal fan of a floor-standing air conditioner is usually fixed, the fan outlet can only consistently face one outlet. When switching to another outlet, the airflow is directly impacted by the air deflector because the outlet the fan was facing is closed, leading to insufficient airflow and making it difficult to achieve optimal cooling and heating performance simultaneously.

[0047] To address this issue, related technologies include installing a rotatable air guide plate at the fan outlet. Rotating the air guide plate changes the fan's airflow direction, directing the airflow to another outlet. However, this method has drawbacks. The air guide plate partially blocks the fan outlet, reducing the fan's airflow and resulting in less than ideal airflow performance. Furthermore, the power required for the motor to drive the air guide plate is relatively high, as the air guide plate needs to resist the thrust of the fan's airflow to rotate.

[0048] Based on this, refer to Figures 1 to 3 As shown, the indoor unit 1000 of this utility model includes a housing 100, a fan 200, and a first drive device 300. The indoor unit 1000 can be a cabinet air conditioner.

[0049] Reference Figures 1 to 3As shown, the housing 100 has a cavity 110. A first air inlet 120 is provided on one side of the housing 100, which is connected to the cavity 110. A first air outlet 130 and a second air outlet 140 are provided on the other side of the housing 100, both of which are connected to the cavity 110. The first air outlet 130 and the second air outlet 140 are arranged sequentially from top to bottom. For example, the first air inlet 120 can be arranged on the rear side of the housing 100, and the first air outlet 130 and the second air outlet 140 can be arranged on the front side of the housing 100. Air is drawn in from the rear side of the housing 100 and air is discharged from the front side of the housing 100. The fan 200 is rotatably disposed within the cavity 110. The first drive device 300 is used to drive the fan 200 to rotate, or it can be understood that the first drive device 300 drives the entire fan 200 to swing up and down. It should be noted that the first drive device 300 drives the entire fan 200 to rotate, so that the air outlet of the fan 200 can deliver air towards the first air outlet 130 or the second air outlet 140. The first drive device 300 can be a motor.

[0050] In this embodiment, the indoor unit 1000 of the air conditioner can drive the fan 200 to rotate via the first drive device 300, thereby changing the airflow direction of the fan 200. This facilitates the airflow from the fan 200 out of a specific air outlet. For example, during cooling, the first drive device 300 can be controlled to drive the fan 200 towards the first air outlet 130; during heating, the first drive device 300 can be controlled to drive the fan 200 towards the second air outlet 140. This greatly improves the effect of pressing down the hot air during heating and significantly enhances the cooling efficiency. It achieves both foot warming effect and uniform heating layering, and can simultaneously take into account the air output effect of cooling and heating, thus achieving a comfortable temperature. Furthermore, since there are no obstructions at the air outlet of the fan 200, the air volume of the fan 200 is not affected, resulting in better air output effect, better cooling comfort, better uniformity, and less air volume loss when switching between cooling and heating. Compared with the related technology where the air guide plate at the air outlet of the fan is rotated, the resistance of driving the entire fan 200 to rotate alone in this embodiment is lower, so the power of the first drive device 300 is lower.

[0051] It should be noted that when there is only one fan 200, the fan 200 can be positioned at either the first air outlet 130 or the second air outlet 140. That is, the fan 200 can be at the same height as either the first air outlet 130 or the second air outlet 140, ensuring that the fan 200's outlet faces either the first air outlet 130 or the second air outlet 140. It should be noted that regardless of which air outlet the fan 200 corresponds to, the first drive device 300 will always drive the fan 200 to deliver air towards the designated outlet. When there are two fans 200, such as... Figure 2As shown, the two fans 200 can be arranged corresponding to the first air outlet 130 and the second air outlet 140 respectively. The two fans 200 are arranged at intervals along the height direction of the housing 100. This arrangement allows the two fans 200 to deliver air to the first air outlet 130 and the second air outlet 140 respectively. There are two first drive devices 300, and the two first drive devices 300 drive the two fans 200 to rotate independently.

[0052] Reference Figures 1 to 3 As shown, in some embodiments, a first air guide assembly 400 is provided at the first air outlet 130, and a second air guide assembly 500 is provided at the second air outlet 140. The first air guide assembly 400 can open or close the first air outlet 130, and the second air guide assembly 500 can open or close the second air outlet 140. The air conditioner indoor unit 1000 has a cooling mode and a heating mode, as shown in the figure. Figure 4 and Figure 5 As shown, when the indoor unit 1000 of the air conditioner is in cooling mode, the following control can be executed: the first air guide assembly 400 opens the first air outlet 130, and the second air guide assembly 500 closes the second air outlet 140. The first drive device 300 drives the fan 200 to rotate, causing the fan 200 to deliver air towards the first air outlet 130. In this way, cold air can flow out from the higher-positioned first air outlet 130. Since the fan 200 delivers air towards the first air outlet 130, and the airflow direction of the fan 200 is consistent with the airflow direction of the first air outlet 130, it does not affect the airflow volume of the fan 200, resulting in good airflow performance. The cold air flowing out from the first air outlet 130, due to its higher density, will naturally fall, resulting in good cooling performance. (Refer to...) Figure 6 and Figure 7 As shown, when the indoor unit 1000 of the air conditioner is in heating mode, the following control can be executed: the air guide assembly closes the first air outlet 130, and the second air guide assembly 500 opens the second air outlet 140. The first drive device 300 drives the fan 200 to rotate, so that the fan 200 delivers air towards the second air outlet 140. In this way, hot air can flow out from the lower-positioned second air outlet 140. Since the fan 200 delivers air towards the second air outlet 140, and the airflow direction of the fan 200 is consistent with the airflow direction of the second air outlet 140, the airflow volume of the fan 200 is not affected, and the airflow effect is good. The cold air flowing out from the second air outlet 140 will naturally rise due to its lower density, resulting in a better heating effect.

[0053] In some other embodiments, the first drive device 300 can drive the fan 200 to swing up and down repeatedly. At this time, the indoor unit 1000 of the air conditioner can be understood as being in the up-and-down sweep mode, and the airflow intermittently flows out from the first air outlet 130 and the second air outlet 140 to achieve the air outlet effect of up-and-down sweep.

[0054] Reference Figures 1 to 3As shown, in some embodiments, the fan 200 is a centrifugal fan with its axis arranged horizontally. The first drive device 300 drives the entire fan 200 to rotate around the horizontal axis. The fan 200 includes a motor 230, a volute 220, and a rotor 210. The rotor 210 is located inside the volute 220. The motor 230 drives the rotor 210 to rotate. The volute 220 is also provided with an air outlet 221. When the first drive device 300 drives the fan 200 to rotate, the air outlet 221 rotates together with the volute 220, thereby changing the orientation of the air outlet 221 and changing the air outlet direction of the fan 200. The fan 200 draws air in axially and discharges air radially. The volute 220 has a second air inlet 222 on one side along the axial direction. In this case, the fan 200 can be understood as a single-suction centrifugal fan. Alternatively, the volute 220 may have a second air inlet 222 on both sides along the axial direction. In this case, the fan 200 can be understood as a double-suction centrifugal fan.

[0055] Reference Figures 2 to 3 As shown, in some embodiments, the inner wall of the cavity 110 defines an air guide channel 150, which is arranged along the height direction of the housing 100. The air guide channel 150 connects the first air outlet 130 and the second air outlet 140. (Refer to...) Figure 2 As shown, the air guide channel 150 has an opening 151 on the side opposite to the first air outlet 130. A portion of the structure of the air outlet 221 extends into the opening 151, allowing the air outlet 221 to directly deliver air into the air guide channel 150. The air guide channel 150 can guide the airflow from the air outlet 221 to the first air outlet 130 or the second air outlet 140. The airflow within the air guide channel 150 will not flow towards the first air inlet 120, thus avoiding interference between the air inlet and outlet. Alternatively, the air guide channel 150 can be understood as forming an air outlet cavity, with the portion of the cavity 110 outside the air guide channel 150 serving as the air inlet cavity. The air guide channel 150 divides the cavity 110 into the air inlet cavity and the air outlet cavity. The air inlet of the fan 200 is located within the air inlet cavity, and the air outlet of the fan 200 is located within the air outlet cavity, thus preventing interference between the air inlet and outlet.

[0056] Reference Figure 2 and Figure 3As shown, in some embodiments, the indoor unit 1000 of the air conditioner also includes a heat exchanger 600, which can be an evaporator. The heat exchanger 600 is arranged in the cavity 110 and is set corresponding to the first air inlet 120, so that the heat exchanger 600 covers the first air inlet 120, ensuring that the outside airflow enters the cavity 110 from the first air inlet 120 and directly exchanges heat with the heat exchanger 600, resulting in high heat exchange efficiency. Because the air outlet 221 of the fan 200 extends into the opening 151 of the air guide channel 150, the second air inlet 222 of the fan 200 is located outside the air guide channel 150. This can be understood as the air guide channel 150 separating the second air inlet 222 and the air outlet 221, thus preventing mutual interference between the incoming and outgoing air. Furthermore, the heat exchanger 600 is mounted on the side of the fan 200 away from the air guide channel 150, covering the second air inlet 222. This arrangement allows the airflow to exchange heat with the heat exchanger 600 before entering the second air inlet 222, resulting in higher heat exchange efficiency. Specifically, as... Figure 3 As shown, viewed from above, the heat exchanger 600 has an n-shaped structure and is enclosed on the rear side of the fan 200.

[0057] It should be noted that since the entire fan 200 is rotatable, the air outlet 221 also rotates with the fan 200. Therefore, there is a certain gap between the air outlet 221 and the opening 151 to allow the air outlet 221 to move. This can also be understood as the size of the opening 151 being larger than the size of the air outlet 221. Based on this, refer to... Figure 5 As shown, in some embodiments, the outer wall of the volute 220 is provided with a sealing part, which is used to seal the gap between the volute 220 and the opening 151. This can reduce air leakage in the air guide channel 150 and avoid mutual interference between the inlet and outlet air. The sealing part can be a sealing plate, foam or sealing cotton, etc.

[0058] Reference Figure 5As shown, in some embodiments, the sealing part includes a first sealing plate 223 and a second sealing plate 224. The first sealing plate 223 is located above the second sealing plate 224. The first sealing plate 223 and the second sealing plate 224 can be flat plate structures. Both the first sealing plate 223 and the second sealing plate 224 extend radially along the volute 220. In some embodiments, the interval angle between the first sealing plate 223 and the second sealing plate 224 can be set according to the rotatable angle of the fan 200. For example, the first driving device 300 can drive the fan 200 to rotate 90 degrees to adjust the air outlet direction. The first sealing plate 223 and the second sealing plate 224 can be spaced 90 degrees apart from each other. When the fan 200 is in two extreme positions, the first sealing plate 223 or the second sealing plate 224 just seals the gap between the volute 220 and the opening 151. In this embodiment, by setting the first sealing plate 223 and the second sealing plate 224, the upper and lower sides of the volute 220 can be sealed, resulting in a better sealing effect and reducing air leakage in the air guide channel 150.

[0059] Specifically, refer to Figure 5 As shown, taking a higher-positioned fan 200 as an example, when the air outlet 221 of the fan 200 faces the first air outlet 130, the second sealing plate 224 is in contact with the outer wall of the air guide channel 150, thereby sealing the gap between the lower side of the volute 220 and the opening 151. Meanwhile, the upper edge of the air outlet 221 is in contact with the upper edge of the opening 151, thus sealing the gap between the upper side of the volute 220 and the opening 151. (Refer to...) Figure 7 As shown, taking a higher-positioned fan 200 as an example, when the air outlet 221 of the fan 200 faces the second air outlet 140, the first sealing plate 223 fits against the outer wall of the air guide channel 150, thereby sealing the gap between the upper side of the volute 220 and the opening 151. Meanwhile, the outer wall of the volute tongue of the volute 220 fits against the lower edge of the opening 151, thus sealing the gap between the lower side of the volute 220 and the opening 151. In this way, when the fan 200 supplies air to the first air outlet 130 or the second air outlet 140, the air leakage in the air guide channel 150 can be reduced. The sealing effect is roughly the same for the lower-positioned fan 200.

[0060] Reference Figure 3As shown, in some embodiments, the indoor unit 1000 of the air conditioner further includes a rotating shaft 310, a first gear 320, and a second gear 330. The inner wall of the housing 100 has a shaft hole, and the rotating shaft 310 is rotatably connected to the shaft hole. The rotating shaft 310 extends horizontally and is fixedly connected to the fan 200. The rotating shaft 310 can drive the entire fan 200 to rotate together. The first gear 320 is fixedly connected to the rotating shaft 310, and the rotating shaft 310 rotates along with the first gear 320. The second gear 330 is fixedly connected to the output end of the first drive device 300, which can be a motor. The second gear 330 meshes with the first gear 320. When the output end of the first drive device 300 rotates, the second gear 330 can drive the first gear 320 to rotate, thereby driving the fan 200 to rotate through the rotating shaft 310. This embodiment mainly uses gears to achieve transmission, resulting in relatively smooth transmission.

[0061] Reference Figure 11 As shown, in some embodiments, the first air guide assembly 400 and the second air guide assembly 500 have the same structure. Taking the first air guide assembly 400 as an example, the first air guide assembly 400 includes a swing arm 410, two air guide plates 420, a second drive device 430, a third drive device 440, and a fourth drive device 450. The swing arm 410 is rotatably connected to the housing 100, and the two air guide plates 420 are respectively rotatably connected to the swing arm 410. The rotation axis 310 of the swing arm 410 and the rotation axis 310 of the air guide plate 420 are respectively parallel to the rotation axis 310 of the fan 200, that is, the rotation axis 310 of the swing arm 410 is set in the horizontal direction. The second drive device 430 is used to drive the swing arm 410 to rotate relative to the housing 100. The third drive device 440 and the fourth drive device 450 respectively drive the two air guide plates 420 to rotate relative to the swing arm 410. The second drive unit 430, the third drive unit 440, and the fourth drive unit 450 can be motors.

[0062] In this embodiment, refer to Figure 5 As shown, the swing arm 410 can retract the two air guide plates 420 into the air guide channel 150, bringing them closer to the air outlet 221 of the fan 200, resulting in better air guiding effect. Since the two air guide plates 420 do not protrude from the air outlet, they reduce the space they occupy. The two air guide plates 420 can be parallel to each other, such as... Figure 4 and Figure 5 As shown, when the fan 200 delivers air to the first air outlet 130, both air guide plates 420 tilt upwards, further guiding the airflow from the first air outlet 130 upwards, thus increasing the air outlet height and improving the cooling effect. Figure 6 and Figure 7As shown, when the fan 200 delivers air to the second air outlet 140, both air guide plates 420 tilt downwards, further guiding the airflow from the second air outlet 140 downwards. This reduces the air outlet height, improves the effect of pressing down the hot air during heating, and enhances the foot warming effect and the uniformity of heating stratification. Figure 8 and Figure 9 As shown, when both the first air outlet 130 and the second air outlet 140 are in the open state, the air guide plate 420 at the first air outlet 130 is tilted upward and the air guide plate 420 at the second air outlet 140 is tilted downward, with a large span of air outlet angle, thereby achieving the effect of dual airflow from top to bottom and further expanding the air outlet angle of the whole machine.

[0063] Since the third drive unit 440 and the fourth drive unit 450 each independently control the rotation of the two guide vanes 420 relative to the swing arm 410, in some embodiments, the two guide vanes can be made to form an angle with each other, such as... Figure 10 As shown, the two deflectors form a V-shape, which guides part of the airflow upwards and part of the airflow downwards, resulting in a larger airflow angle, a wider airflow coverage area, and better performance.

[0064] In some other embodiments, the third drive device 440 and the fourth drive device 450 can also drive the two air guide plates 420 to swing up and down synchronously, thereby achieving an up-and-down sweeping effect at the corresponding air outlet.

[0065] It is understood that the third drive device 440 and the fourth drive device 450 are both fixedly connected to the swing arm 410. It can be understood that the swing arm 410 provides a mounting fulcrum for the third drive device 440 and the fourth drive device 450, which can save the mounting frame structure used to install the third drive device 440 and the fourth drive device 450 and reduce the space occupied.

[0066] In some embodiments, a third air outlet can be arranged between the first air outlet 130 and the second air outlet 140. The third air outlet is connected to the air guide channel 150, which can realize air outlet from the middle position of the housing 100. Combined with the first air outlet 130 and the second air outlet 140 in the above embodiment, the vertical dual-flow air outlet or four-way air outlet effect can be formed, which can realize five-dimensional air supply, with diverse air supply effects, and can meet most of the user's air supply needs.

[0067] Some embodiments of this utility model also provide an air conditioner, including the air conditioner indoor unit 1000 of the above embodiments. By using the air conditioner indoor unit 1000 of the above embodiments, the air supply direction of the fan 200 can be changed, which is conducive to the smooth flow of air from the fan 200 out of a specific air outlet. It can simultaneously take into account the air supply effect of cooling and heating, and achieve a comfortable cooling and heating effect. Furthermore, since there is no obstruction at the air outlet of the fan 200, the air volume of the fan 200 will not be affected, the air supply effect is better, the cooling comfort is better, the uniformity is better, and the air volume loss when switching between cooling and heating is smaller. Compared with the related technology where the air guide plate at the air outlet of the fan is rotated, the resistance of driving the entire fan 200 to rotate alone in this embodiment is lower, so the power of the first drive device 300 is lower.
