Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly, to an air conditioner. Background Art

[0002] During the operation of an air conditioner, the blower sucks indoor air into the air duct, and after flowing through the heat exchanger, it is sent out through the air duct again to heat or cool the indoor air, so as to achieve the effect of adjusting the indoor temperature.

[0003] In the related art, in order to ensure that the heat exchanger operates at a reasonable operating point, there is often a large temperature difference between the air blown out from the air conditioner and the environment. For example, when the air conditioner operates in the cooling mode and the ambient temperature is about 25°C, the outlet air temperature is often less than 8°C. If the too cold air is directly blown on people, it will make people feel very uncomfortable. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, the present invention provides an air conditioner.

[0006] The present invention provides an air conditioner, comprising: a housing, an air duct is arranged in the housing, and the air duct includes a communicating air inlet and an air outlet; a heat exchanger, arranged in the air duct and located between the air inlet and the air outlet; a driving device, arranged in the air duct, driving air flow to enter the air duct from the air inlet, and at least part of the air flow is discharged from the air outlet after being heat-exchanged by the heat exchanger; a mixing mechanism, movably arranged in the air duct, when the mixing mechanism moves to the first position, part of the air flow is discharged from the air outlet without passing through the heat exchanger.

[0007] The air conditioner proposed by the present invention includes a housing, a driving device, a heat exchanger and a mixing mechanism. Among them, an air duct is arranged in the housing, and the air duct includes a communicating air inlet and an air outlet. The heat exchanger is arranged in the air duct and is located between the air inlet and the air outlet, and the heat exchanger realizes the cooling and heating capabilities of the air conditioner. The driving device is arranged in the air duct and can drive the external air flow to enter the air duct from the air inlet during operation, and then be discharged from the air outlet through the air duct, realizing the air supply of the air conditioner.

[0008] In addition, the air conditioner proposed by the present invention further includes a mixing mechanism. Among them, the mixing mechanism is arranged in the air duct, and the user can adjust the air conditioner to different operating states through the mixing mechanism, adjust the temperature of the air flow blown out from the air outlet, and ensure that the temperature difference between the air flow blown out from the air outlet and the room temperature is small, avoiding causing discomfort to the user.

[0009] Specifically, when the air mixing mechanism moves to the first position, part of the air flow entering the air duct will directly pass over the heat exchanger and flow towards the air outlet, and this part of the air flow will not exchange heat with the heat exchanger; correspondingly, part of the air flow entering the air duct will pass through the heat exchanger and then flow towards the air outlet, and this part of the air flow exchanges heat with the heat exchanger. The air flow that has exchanged heat and the air flow that has not exchanged heat are mixed in the air duct and then discharged, ensuring that the difference between the air outlet temperature of the air conditioner and the temperature of its surrounding environment is reduced, so as to improve the adaptability of the air conditioner.

[0010] Specifically, when the air mixing mechanism moves to the second position, all the air flow entering the air duct passes through the heat exchanger and then flows towards the air outlet, and all the air flow in the air duct exchanges heat with the heat exchanger. At this time, the ambient temperature of the air conditioner can be quickly adjusted to achieve the effect of rapid cooling or heating.

[0011] Therefore, the air conditioner proposed by the present invention, through the setting of the air mixing mechanism, enables part of the air flow entering the air duct to exchange heat with the heat exchanger, and enables part of the air flow in the air duct to flow directly through the air mixing port without exchanging heat with the heat exchanger; moreover, the air flow that has exchanged heat and the air flow that has not exchanged heat can be mixed in the air duct and then discharged, effectively ensuring that the difference between the air outlet temperature of the air conditioner and the temperature of its surrounding environment is reduced, improving the comfort of using the air conditioner. Furthermore, the user can also control all the air flow in the air duct to exchange heat with the heat exchanger and then be discharged, achieving rapid cooling and heating, making the air conditioner have extremely strong adaptability and functionality.

[0020] In some possible design solutions, the flow dividing member includes a first flow dividing plate and a second flow dividing plate connected to each other. At least part of the first flow dividing plate extends towards the inner wall of the air duct, and at least part of the second flow dividing plate extends upwards.

[0021] In some possible design solutions, a first partition plate is arranged in the housing, and at least part of the first partition plate extends upwards; the mixing air inlet is located between the first partition plate and the heat exchanger.

Specific Embodiments

[0056] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0057] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways than those specifically described herein, and thus, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0058] The following refers to Figures 1 to 21 to describe an air conditioner provided according to some embodiments of the present invention, where the dashed arrows in the figures indicate the air flow direction.

[0059] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a first embodiment of the present invention provides an air conditioner, including: a housing 102, a driving device 110, a heat exchanger 112, and a mixing air mechanism 114.

[0060] Among them, a duct 104 is provided inside the housing 102, and the duct 104 includes an air inlet 106 and an air outlet 108 that are connected and communicate with each other. The heat exchanger 112 is disposed inside the duct 104, and the heat exchanger 112 can achieve the cooling and heating capabilities of the air conditioner. The driving device 110 is disposed inside the duct 104, and can drive the external air flow to enter the duct 104 from the air inlet 106 during operation, and then be discharged from the duct 104 through the air outlet 108 to achieve the air supply of the air conditioner.

[0061] In addition, as Figure 2 , Figure 3 and Figure 4 shown, the air conditioner proposed by the present invention further includes a mixing air mechanism 114. Among them, the mixing air mechanism 114 is disposed inside the duct 104, and the user can adjust the temperature of the air flow blown out from the air outlet 108 through the mixing air mechanism 114 to ensure that the temperature difference between the air flow blown out from the air outlet 108 and the room temperature is small, so as to avoid causing discomfort to the user.

[0062] Specifically, as Figure 4 and Figure 7 shown, when the mixing air mechanism 114 moves to the first position, a part of the air flow entering the duct 104 will directly bypass the heat exchanger 112 and flow to the air outlet 108, and this part of the air flow will not exchange heat with the heat exchanger 112; correspondingly, a part of the air flow entering the duct 104 will flow to the air outlet 108 after passing through the heat exchanger 112, and this part of the air flow exchanges heat with the heat exchanger 112. And, the air flow that has exchanged heat and the air flow that has not exchanged heat are mixed in the duct 104 and then discharged, ensuring that the temperature difference between the air output of the air conditioner and the temperature of its surrounding environment is reduced, so as to improve the adaptability of the air conditioner.

[0063] Specifically, as Figure 3 and Figure 6As shown in the figure, when the air mixing mechanism 114 moves to the second position, all the air flowing into the air duct 104 passes through the heat exchanger 112 and then flows towards the air outlet 108, and all the air in the air duct 104 exchanges heat with the heat exchanger 112. At this time, the ambient temperature of the air conditioner can be quickly adjusted to achieve the effect of rapid cooling or heating.

[0064] In addition, as Figure 2 and Figure 5 shown, when the air mixing mechanism 114 moves to any position between the first position and the second position, a small amount of air will pass through the air mixing port 120 and directly flow towards the air outlet 108, and a small amount of air exchanges heat with the heat exchanger 112.

[0065] Therefore, for the air conditioner proposed by the present invention, the user can divide the air flowing into the air duct 104 into two parts through the air mixing mechanism 114, so that a part of the air exchanges heat with the heat exchanger 112, a part of the air does not exchange heat with the heat exchanger 112, and the air that has exchanged heat and the air that has not exchanged heat are mixed in the air duct 104 and then discharged, effectively ensuring that the difference between the air outlet temperature of the air conditioner and the ambient temperature of its location is reduced, and improving the comfort of using the air conditioner. Moreover, the user can also control all the air in the air duct 104 to exchange heat with the heat exchanger 112 and then be discharged to achieve rapid cooling and heating, making the air conditioner have strong adaptability and functionality.

[0066] In addition, as Figure 8 and Figure 9 shown, the air mixing mechanism 114 can be arranged on the top of the heat exchanger 112, the air mixing mechanism 114 can be arranged at the bottom of the heat exchanger 112, or the air mixing mechanism 114 can be arranged on both the top and the bottom of the heat exchanger 112 at the same time.

[0067] The second embodiment of the present invention proposes an air conditioner. On the basis of the first embodiment, further:

[0068] As Figure 2 、 Figure 3 and Figure 4 shown, the air conditioner further includes an air mixing port 120. Among them, the air mixing port 120 is located between the heat exchanger 112 and the inner wall of the air duct 104, and the air mixing mechanism 114 is movably arranged in the air duct 104 and can be used to open or close the air mixing port 120.

[0069] Specifically, as Figure 4 and Figure 7As shown, when the air mixing mechanism 114 moves to the first position, the air mixing mechanism 114 opens the air mixing port 120. At this time, a part of the air flow entering the air duct 104 will directly flow through the air mixing port 120 to the air outlet 108, and this part of the air flow will not exchange heat with the heat exchanger 112; correspondingly, a part of the air flow entering the air duct 104 will flow through the heat exchanger 112 and then to the air outlet 108, and this part of the air flow exchanges heat with the heat exchanger 112. Moreover, the air flow that has exchanged heat and the air flow that has not exchanged heat are mixed in the air duct 104 and then discharged, ensuring that the temperature difference between the air outlet temperature of the air conditioner and the ambient temperature of its location is reduced, so as to improve the adaptability of the air conditioner.

[0070] Specifically, as Figure 3 and Figure 6 shown, when the air mixing mechanism 114 moves to the second position, the air mixing mechanism 114 closes the air mixing port 120. At this time, all the air flow entering the air duct 104 flows through the heat exchanger 112 and then to the air outlet 108, and all the air flow in the air duct 104 exchanges heat with the heat exchanger 112. At this time, the ambient temperature of the air conditioner can be quickly adjusted to achieve the effect of rapid cooling or heating.

[0071] Specifically, as Figure 2 and Figure 5 shown, the air mixing mechanism 114 moves to the third position. At this time, the air mixing mechanism 114 opens a part of the air mixing port 120, thereby ensuring that a small amount of air flow will directly flow through the air mixing port 120 and then to the air outlet 108, and a small amount of air flow exchanges heat with the heat exchanger 112.

[0072] Specifically, the above-mentioned first position is the position where the flow dividing member 132 fully opens the air mixing port 120, the above-mentioned second position is the position where the flow dividing member 132 fully closes the air mixing port 120, and the first position is the position where the flow dividing member 132 partially opens the air mixing port 120.

[0073] The third embodiment of the present invention proposes an air conditioner. On the basis of the first embodiment, further:

[0074] The air mixing mechanism 114 includes a flow dividing member 132. The flow dividing member 132 is movably disposed in the air duct 104 and can be used to open or close the air mixing port 120.

[0075] Specifically, as Figure 4 and Figure 7As shown, when the flow diverter 132 moves to the first position, the flow diverter 132 opens the air mixing opening 120. At this time, a part of the air flow entering the air duct 104 will directly flow through the air mixing opening 120 to the air outlet 108, and this part of the air flow will not exchange heat with the heat exchanger 112; correspondingly, a part of the air flow entering the air duct 104 will flow through the heat exchanger 112 and then to the air outlet 108, and this part of the air flow exchanges heat with the heat exchanger 112. Moreover, the air flow that has exchanged heat and the air flow that has not exchanged heat are mixed in the air duct 104 and then discharged, ensuring that the temperature difference between the air outlet temperature of the air conditioner and the ambient temperature of its location is reduced, so as to improve the adaptability of the air conditioner.

[0076] Specifically, as Figure 3 and Figure 6 shown, when the flow diverter 132 moves to the second position, the flow diverter 132 closes the air mixing opening 120. At this time, all the air flow entering the air duct 104 flows through the heat exchanger 112 and then to the air outlet 108, and all the air flow in the air duct 104 exchanges heat with the heat exchanger 112. At this time, the ambient temperature of the air conditioner can be quickly adjusted to achieve the effect of rapid cooling or heating.

[0077] Specifically, as Figure 2 and Figure 5 shown, the flow diverter 132 moves to the third position. At this time, the flow diverter 132 opens a part of the air mixing opening 120, so as to ensure that a small amount of air flow will directly flow through the air mixing opening 120 and then to the air outlet 108, and a small amount of air flow exchanges heat with the heat exchanger 112.

[0078] The fourth embodiment of the present invention proposes an air conditioner. On the basis of the first embodiment, further:

[0079] As Figure 2 、 Figure 3 and Figure 4 shown, the heat exchanger 112 is located in the middle of the air duct 104, and the air duct 104 further includes an air inlet section 116 and an air mixing section 118 that are connected and communicate. Among them, the air inlet section 116 is located between the air inlet 106 and the heat exchanger 112, and the air mixing section 118 is located between the heat exchanger 112 and the air outlet 108. In this way, during the operation of the air conditioner, the air flow outside the air conditioner first enters the air inlet section 116 of the air duct 104 through the air inlet 106 and flows to the positions where the heat exchanger 112 and the air mixing mechanism 114 are located.

[0080] At this time, when the flow divider 132 moves to the first position, part of the air flow in the air inlet section 116 will flow through the heat exchanger 112 to the air mixing section 118, and this part of the air flow exchanges heat with the heat exchanger 112; part of the air flow in the air inlet section 116 will directly flow from the air mixing port 120 to the air mixing section 118, and this part of the air flow does not exchange heat with the heat exchanger 112; in the air mixing section 118, the heated air flow and the unheated air flow are mixed and then discharged. In addition, when the flow divider 132 moves to the second position, all the air flow in the air inlet section 116 will exchange heat with the heat exchanger 112 and flow to the air mixing section 118.

[0081] Therefore, through the above settings of the air inlet section 116 and the air mixing section 118, it can be ensured that when the flow divider 132 moves to the first position, the heated air flow and the unheated air flow are mixed inside the air duct 104 and then discharged, which ensures that on the one hand, the temperature of the air flow discharged from the air outlet 108 is appropriate, and on the other hand, the temperature of the air flow discharged from the air outlet 108 is uniform. Furthermore, while ensuring that the air supply of the air conditioner does not cause discomfort to the user, the comfort of the air supply of the air conditioner is further improved.

[0082] In addition, the air conditioner proposed in this embodiment has all the beneficial effects of the air conditioner in Embodiment 1, and can mix and discharge the heated air flow and the unheated air flow in the air duct 104, effectively ensuring that the difference between the air outlet temperature of the air conditioner and the temperature of its surrounding environment is reduced, and improving the comfort of using the air conditioner. This will not be specifically elaborated here.

[0083] The fifth embodiment of the present invention proposes an air conditioner, which further:

[0084] The air conditioner further includes a detection device (not shown in the figure) and a control device (not shown in the figure). Among them, the detection device can be used to detect the ambient temperature of the air conditioner, and the controller is connected to the detection device and the air mixing mechanism 114, and can be used to control the operation of the air mixing mechanism 114 according to the detection result of the detection device, and then adjust the proportion of the air flow in the air duct 104 that does not exchange heat with the heat exchanger, so as to increase the temperature of the air flow discharged from the air outlet 108. And through the cooperation of the above detection device and the control device, the intelligence of the air conditioner can be greatly improved, and the automatic control and adjustment of the air conditioner can be realized.

[0085] Specifically, taking the air mixing mechanism 114 moving to the first position and opening the air mixing port 120 as an example, the working principle of the above detection device and control device will be explained:

[0086] During the operation of the air conditioner, the detection device can detect the ambient temperature of the air conditioner; as Figure 2 and Figure 6As shown, when the difference between the ambient temperature of the air conditioner and the set temperature of the air conditioner is large, the control device controls the opening degree of the air mixing mechanism 114 to decrease. At this time, a small part of the air mixing opening 120 is in the open state. At this time, only a small part of the air flow directly passes through the air mixing opening 120 without exchanging heat with the heat exchanger 112. Therefore, the proportion of the air flow that has exchanged heat in the mixed air flow is relatively large, which can ensure that the temperature of the mixed air flow is relatively low for rapid refrigeration.

[0087] As Figure 4 and Figure 7 shown, when the difference between the ambient temperature of the air conditioner and the set temperature of the air conditioner is small, the control device controls the opening degree of the air mixing mechanism 114 to increase. At this time, most of the air mixing opening 120 is in the open state. At this time, most of the air flow directly passes through the air mixing opening 120 without exchanging heat with the heat exchanger 112. Therefore, the proportion of the air flow that has not exchanged heat in the mixed air flow is relatively large, which can ensure that the mixed air flow is close to the room temperature and can ensure the comfort of the user.

[0088] In a specific embodiment, the above detection device can adopt a temperature sensor; in addition, the detection device can be arranged on the housing 102.

[0089] In addition, the air conditioner proposed in this embodiment has all the beneficial effects of the air conditioner in Embodiment 1, and can mix the air flow that has exchanged heat with the air flow that has not exchanged heat in the air duct 104 and then discharge it, effectively ensuring that the difference between the air outlet temperature of the air conditioner and the ambient temperature where it is located is reduced, and improving the comfort of using the air conditioner. Details are not described herein again.

[0090] The sixth embodiment of the present invention proposes an air conditioner. On the basis of Embodiment 3, further:

[0091] As Figure 2 and Figure 9 shown, the heat exchanger 112 is an annular structure distributed around the circumference of the driving device 110. That is to say, the heat exchanger 112 is an annular heat exchanger and is distributed on the periphery of the driving device 110. The air flow in the air duct 104 can exchange heat 360° on the periphery of the driving device 110. In this way, on the one hand, it can ensure the heat exchange area of the air flow in the air duct 104, thereby improving the refrigeration and heating capabilities of the air conditioner. On the other hand, it can ensure the beautiful overall appearance of the air conditioner and ensure that the overall size of the air conditioner is appropriate.

[0092] In this embodiment, further, the flow splitter 132 is located between the heat exchanger 112 and the driving device 110. In this way, when the flow splitter 132 moves to the first position, the flow splitter 132 opens the air mixing port 120, and a part of the air flow entering the air duct 104 will directly flow through the air mixing port 120 to the air outlet 108, and this part of the air flow will not exchange heat with the heat exchanger 112; correspondingly, a part of the air flow entering the air duct 104 will flow through the heat exchanger 112 and then flow to the air outlet 108, and this part of the air flow exchanges heat with the heat exchanger 112. The heated air flow and the unheated air flow are mixed in the air duct 104 and then discharged, ensuring that the temperature difference between the air outlet temperature of the air conditioner and the ambient temperature where it is located is reduced, so as to improve the adaptability of the air conditioner.

[0093] The seventh embodiment of the present invention proposes an air conditioner. On the basis of the sixth embodiment, further:

[0094] After the air conditioner is assembled, there is a certain area between the heat exchanger, the driving device, and the inner wall of the air duct 104, and then the air mixing port is directly formed through this area. Specifically, the air mixing port 120 is an annular port distributed along the circumference of the driving device 110.

[0095] In addition, as Figure 2 、 Figure 3 and Figure 4 shown, the flow splitter 132 is liftably arranged in the air duct 104. In this way, when the flow splitter 132 moves to the first position, the flow splitter 132 is at a relatively high position, and at this time the air mixing port 120 is in an open state; when the flow splitter 132 moves to the second position, the flow splitter 132 is at a relatively low position, and at this time the air mixing port 120 is in a closed state. Moreover, the heat exchanger 112 is located on the circumferential side of the driving device 110, which can effectively ensure the heat exchange area between the heat exchanger 112 and part of the air flow, and thus improve the cooling and heating capabilities of the air conditioner.

[0096] In addition, regarding the driving method of the flow splitter 132, no specific limitation is made in this embodiment. The engagement of a rack and a gear can be used for driving (that is, a rack is provided on the flow splitter 132, and the motor drives the flow splitter 132 to lift through the engagement of the gear and the rack). As long as the lifting of the flow splitter 132 can be achieved, it is feasible, and those skilled in the art can also understand it.

[0097] In this embodiment, further, the flow splitter 132 includes a first flow splitting plate 122 and a second flow splitting plate 124 that are connected. Among them, at least part of the first flow splitting plate 122 is horizontally arranged and extends towards the inner wall of the air duct 104; at least part of the second flow splitting plate 124 extends upwards.

[0098] In this way, when the flow diverter 132 moves to the first position, the flow diverter 132 is at a relatively high position. At this time, the first flow dividing plate 122 can open the air mixing opening 120, and since at least a part of the first flow dividing plate 122 is horizontally arranged, the extending direction of the first flow dividing plate 122 is the same as the flowing direction of the air flow in the air inlet section 116 of the air duct 104, so that the first flow dividing plate 122 can play a role in flow diversion to guide the first part of the air flow into the air mixing opening 120. In addition, since at least a part of the second flow dividing plate 124 is vertically arranged, it can play an isolating effect between the air mixing opening 120 and the heat exchanger 112. On the one hand, it ensures that the air flow entering the air mixing opening 120 does not contact the heat exchanger 112, and on the other hand, it ensures that the second flow dividing plate 124 guides the air flow in the air mixing opening 120 to flow.

[0099] In this embodiment, further, as Figure 5 、 Figure 6 and Figure 7 shown, a first partition plate 126 is arranged in the housing 102. Among them, the first partition plate 126 extends upward, and the extending height of the first partition plate 126 matches the extending height of the second flow dividing plate 124. In addition, the air mixing opening 120 is located between the first partition plate 126 and the heat exchanger 112, and the extending directions of the first partition plate 126 and the second flow dividing plate 124 are the same.

[0100] In this way, as Figure 6 shown, when the flow diverter 132 moves to the second position, the flow diverter 132 is at a relatively low position. At this time, the edge of the first flow dividing plate 122 abuts against the top of the first partition plate 126, thereby closing the air mixing opening 120, so that all the air in the air duct 104 exchanges heat with the heat exchanger 112.

[0101] In this embodiment, further, as Figure 2 、 Figure 3 and Figure 4 shown, the air mixing openings 120 are distributed around the driving device 110; the air mixing openings 120 are annular openings distributed along the circumference of the driving device 110 and are located between the driving device 110 and the heat exchanger 112. Correspondingly, the air outlet 108 is also an annular opening distributed along the circumference of the driving device 110 and is located on the outer periphery of the heat exchanger 112. In this way, firstly, it ensures that the air conditioner blows air towards the peripheral side, and secondly, it ensures the heat exchange area of the heat exchanger 112, thereby improving the cooling and heating capabilities of the air conditioner.

[0102] In a specific embodiment, the controller can control the first flow dividing plate 122 and the second flow dividing plate 124 to open or close the air mixing opening 120 according to the detection results of the detection device, and can control and adjust the opening degree of the air mixing opening 120 to adjust the proportion of the air flow in the air duct 104 that does not exchange heat with the heat exchanger 112.

[0103] In addition, the air conditioner proposed in this embodiment has all the beneficial effects of the air conditioner in Embodiment 1. It can mix the heat-exchanged air flow and the non-heat-exchanged air flow in the air duct 104 and then discharge them, effectively ensuring that the temperature difference between the air outlet temperature of the air conditioner and the ambient temperature where it is located is reduced, and improving the comfort of using the air conditioner. Details are not elaborated herein.

[0104] The eighth embodiment of the present invention proposes an air conditioner. On the basis of Embodiment 6, further:

[0105] As Figure 15 、 Figure 16 and Figure 19 shown, a second partition plate 130 is provided in the housing 102. Among them, at least part of the second partition plate 130 is horizontally arranged and extends between the driving devices 110 where the heat exchanger 112 is located, ensuring that the peripheral edge of the second partition plate 130 abuts against the inner side wall of the heat exchanger 112. In addition, the air mixing port 120 is provided at the peripheral edge of the second partition plate 130.

[0106] In this embodiment, further, the flow dividing member 132 is disposed in the air duct 104 in a manner that it can be lifted or rotated. When the flow dividing member 132 is disposed in the air duct 104 in a manner that it can be lifted, when the flow dividing member 132 moves to the first position, there is a gap between the flow dividing member 132 and the inner wall of the air duct 104 to ensure that the flow dividing member 132 opens the air mixing port 120. When the flow dividing member 132 is disposed in the air duct 104 in a manner that it can be rotated, when the flow dividing member 132 moves to the first position, the flow dividing member 132 is staggered with the air mixing port 120 to ensure that the flow dividing member 132 opens the air mixing port 120.

[0107] In addition, regarding the driving manner of the flow dividing member 132, no specific limitation is made in this embodiment. The engagement of a rack and a gear can be used for driving (that is, a rack is provided on the flow dividing member 132, and the motor drives the flow dividing member 132 to lift through the engagement of the gear and the rack). As long as the lifting or rotation of the flow dividing member 132 can be achieved, it is feasible, and those skilled in the art can also understand it.

[0108] As Figure 10 、 Figure 11 、 Figure 17 、and Figure 21 shown, the flow dividing member 132 includes a third flow dividing plate 128. Among them, the third flow dividing plate 128 is disposed in the air duct 104 in a manner that it can be lifted or rotated and can be used to open or close the air mixing port 120.

[0109] As Figure 15 、 Figure 16 、 Figure 18 、 Figure 19 and Figure 21As shown, when the flow divider 132 moves to the first position, the third flow dividing plate 128 opens the air mixing port 120, and the air inlet 106 and the air outlet 108 are in a conducting state. At this time, a part of the air flow entering the air duct 104 will directly flow through the air mixing port 120 to the air outlet 108, and this part of the air flow will not exchange heat with the heat exchanger 112; correspondingly, a part of the air flow entering the air duct 104 will flow through the heat exchanger 112 and then to the air outlet 108, and this part of the air flow exchanges heat with the heat exchanger 112. The heated air flow and the unheated air flow are mixed in the air duct 104 and then discharged, ensuring that the difference between the air outlet temperature of the air conditioner and the ambient temperature of its location is reduced, so as to improve the adaptability of the air conditioner.

[0110] Specifically, as Figure 12 and Figure 20 shown, when the flow divider 132 moves to the second position, the third flow dividing plate 128 closes the air mixing port 120. At this time, the air inlet 106 is disconnected from the air outlet 108. At this time, all the air flow entering the air duct 104 flows through the heat exchanger 112 and then to the air outlet 108, and all the air flow in the air duct 104 exchanges heat with the heat exchanger 112. At this time, the ambient temperature of the air conditioner can be quickly adjusted to achieve the effect of rapid cooling or heating.

[0111] In this embodiment, further, as Figure 15 、 Figure 16 and Figure 19 shown, the air mixing port 120 is an arc-shaped port. Among them, the number of air mixing ports 120 is multiple, and the multiple arc-shaped ports are axially distributed on the periphery of the driving device 110. Correspondingly, the air outlet 108 is an annular port and is located on the outer periphery of the heat exchanger 112. In this way, firstly, it is ensured that the air conditioner blows air towards the periphery, and secondly, the heat exchange area of the heat exchanger 112 is ensured, thereby improving the cooling and heating capabilities of the air conditioner.

[0112] In a specific embodiment, the controller can control the third air flow plate to open or close the air mixing port 120 according to the detection result of the detection device, and can control and adjust the opening degree of the air mixing port 120 to adjust the proportion of the air flow in the air duct 104 that does not exchange heat with the heat exchanger 112.

[0113] In addition, the air conditioner proposed in this embodiment has all the beneficial effects of the air conditioner in Embodiment 1. The heated air flow and the unheated air flow can be mixed in the air duct 104 and then discharged, effectively ensuring that the difference between the air outlet temperature of the air conditioner and the ambient temperature of its location is reduced, and improving the comfort of using the air conditioner. This will not be specifically described here.

[0114] On the basis of Embodiment 7 and Embodiment 8, further, as Figure 8 and Figure 9As shown, the air mixing inlet 120 and the air mixing mechanism 114 can be arranged at the top of the heat exchanger 112, or at the bottom of the heat exchanger 112, or can be arranged at both the top and the bottom of the heat exchanger 112 simultaneously.

[0115] Based on Embodiments 1 to 8, further, as Figure 2 、 Figure 3 and Figure 4 shown, the air inlet 106 of the air duct 104 is arranged towards the bottom of the housing 102, and the air outlet 108 of the air duct 104 is arranged towards the side of the housing 102. During the operation of the air conditioner, the air duct 104 continuously sucks air from the bottom of the air conditioner and sends it to the periphery of the air conditioner. In this way, during the use of the air conditioner, it can be avoided that the air flow blown out from the air outlet 108 directly blows towards the user, and when the air conditioner operates in the cooling or heating mode, it can be further avoided from causing discomfort to the user.

[0116] Based on Embodiments 1 to 8, further, as Figure 2 、 Figure 3 and Figure 4 shown, the housing 102 is an annular housing, the driving device 110 is a centrifugal fan, the heat exchanger 112 is an annular heat exchanger, and the driving device 110 is located in the middle of the heat exchanger.

[0117] In the related art, the air conditioner is provided with two sets of temperature sensors, and the two sets of temperature sensors respectively detect the temperature near the copper tube of the heat exchanger (tube temperature) and the temperature of the space near the air conditioner (ambient temperature). When the fan rotates to send air to the heat exchanger for heat exchange, the compressor works to send refrigerant to the copper tube in the heat exchanger, and the control system enables the two to work together to keep the tube temperature in a relatively constant working condition range, so that the compressor works in the high-efficiency range. However, in order to make the compressor work in the most efficient range, the temperature of the heat exchanger generally can only fluctuate near the designed temperature point, which results in that the air outlet temperature cannot be adjusted by changing the temperature of the heat exchanger, resulting in a large temperature difference between the air sent out by the air conditioner in the related art and the room temperature all the time. If the air flow passing through the heat exchanger directly blows on people without being mixed with the indoor air, it will cause discomfort.

[0118] A specific embodiment of the present invention provides an air conditioner, which is provided with an air mixing mechanism 114, so that the air flow sent out from the fan is divided into two parts, one part is sent to the heat exchanger 112 for heat exchange, and the other part is used to mix with the air flow that has already undergone heat exchange, and then is sent out from the air outlet 108, so that the difference between the air outlet temperature and the ambient temperature becomes smaller, improving the comfort.

[0119] In a specific embodiment, the air conditioner includes a housing 102, a driving device 110, a heat exchanger 112, and a mixed air mechanism 114; a wind channel 104 is provided inside the housing 102, and the wind channel 104 includes an air inlet 106 and an air outlet 108 that are connected and communicate with each other; the driving device 110 is arranged inside the wind channel 104; the heat exchanger 112 is arranged inside the wind channel 104 and is located in the middle of the wind channel 104; a mixed air opening 120 is provided between the heat exchanger 112 and the inner wall of the wind channel 104; the mixed air mechanism 114 includes a movable flow dividing plate. In this way, by controlling the flow dividing plate, the opening degree of the mixed air opening 120 is controlled, and further the air volume passing through the heat exchanger 112 and the air volume used for internal mixing are distributed, so as to achieve the effect of adjusting the outlet air temperature.

[0120] In a specific embodiment, as Figure 2 , Figure 3 and Figure 4 shown, the mixed air mechanism 114 is arranged in the wind channel 104 in a liftable manner, and the mixed air mechanism 114 includes a first flow dividing plate 122 and a second flow dividing plate 124 that are connected; the mixed air opening 120 is annularly located between the heat exchanger 112 and the inner wall of the wind channel 104.

[0121] As Figure 3 and Figure 6 shown, in the stage where the air conditioner needs to quickly refrigerate, the mixed air mechanism 114 is in a closed state. At this time, the first flow dividing plate 122 and the second flow dividing plate 124 close the mixed air opening 120, and all the air sent out from the driving device 110 passes through the heat exchanger 112 for heat exchange; at this time, the refrigeration capacity of the air conditioner is the same as that when the mixed air mechanism 114 is not provided, that is, the mixed air mechanism 114 does not reduce the refrigeration capacity in the stage of quickly refrigerating.

[0122] As Figure 2 , Figure 4 , Figure 5 and Figure 7 shown, when the room temperature is close to the set temperature, the required refrigeration power of the air conditioner decreases, and the mixed air mechanism 114 is in an open state. At this time, the first flow dividing plate 122 and the second flow dividing plate 124 open the mixed air opening 120, a part of the air sent out from the driving device 110 passes through the heat exchanger 112 for heat exchange, and a part flows through the mixed air opening 120 and is used for mixing with the heat-exchanged air; the air blown out by the air conditioner is closer to the room temperature than in the related art, and the comfort of the user will be significantly improved.

[0123] In a specific embodiment, taking the set room temperature as 25 °C, the ratio of the heat-exchanged air flow to the non-heat-exchanged air flow as 1:1 (that is, Figure 2 and Figure 5 shown semi-open state), and the pipe plate temperature of the heat exchanger 112 as 8 °C as an example. Through calculation, the temperature of the air discharged by the air conditioner after mixing is about 16 °C. Compared with the outlet air temperature of 8 °C in the related art, the comfort will be significantly improved.

[0124] In addition, as Figure 11 , as Figure 12 , Figure 13 and Figure 14 shown, an arc-shaped air mixing port 120 can also be directly provided on the housing 102, and the air mixing mechanism 114 is disposed in the air duct 104 in a liftable manner. The air mixing mechanism 114 includes a third diverter plate 128. The third diverter plate 128 is located below the air mixing port 120 and can be used to open or close the air mixing port 120 to adjust the air outlet temperature of the air conditioner.

[0125] In addition, as Figure 11 , as Figure 12 , Figure 13 and Figure 14 shown, an arc-shaped air mixing port 120 can also be directly provided on the housing 102, and the air mixing mechanism 114 is disposed in the air duct 104 in a liftable manner. The air mixing mechanism 114 includes a third diverter plate 128. As Figure 15 and Figure 16 shown, the third diverter plate 128 is located below the air mixing port 120 and can be lifted to open or close the air mixing port 120 to adjust the air outlet temperature of the air conditioner.

[0126] In addition, as Figure 18 , Figure 20 and Figure 21 shown, an arc-shaped air mixing port 120 can also be directly provided on the housing 102. The air mixing mechanism 114 is rotatably disposed in the air duct 104. The air mixing mechanism 114 includes a third diverter plate 128. As Figure 19 shown, the third diverter plate 128 is located below the air mixing port 120 and can be rotated to open or close the air mixing port 120 to adjust the air outlet temperature of the air conditioner.

[0127] In addition, the air mixing port 120 and the air mixing mechanism 114 can be provided at the bottom of the heat exchanger 112, can also be provided at the top of the heat exchanger 112, or can be provided at both the bottom and the top of the heat exchanger 112 at the same time.
