Abstract
Description
Technical Field
[0001] The present application relates to the technical field of air conditioners, and particularly to an indoor air conditioner. Background Art
[0002] An air conditioner, i.e., an air regulator, refers to a device that uses artificial means to adjust and control parameters such as the temperature, humidity, and flow rate of the air in the environment of a building or structure. An air conditioner includes an indoor unit and an outdoor unit, and exchanges heat between the indoor air through the refrigerant flowing between the indoor unit and the outdoor unit to achieve the adjustment of the indoor temperature.
[0003] In the prior art, an indoor air conditioner includes a body, an indoor heat exchanger and a heat exchange fan disposed inside the body, and an air outlet of the air conditioner is provided on the body; a wind deflector is provided at the air outlet of the air conditioner. The heat exchange fan outputs the air flow heat-exchanged by the indoor heat exchanger to the room through the air outlet of the air conditioner; the direction of the wind is changed by the flipping of the wind deflector.
[0004] However, in the above solution, because there is a volute tongue inside the body, the air flow will be output along the tangential direction of the air flow, so the air flow will tend to be output to the side close to the volute tongue, resulting in partial deviation of the air flow. The air outlet direction of the air conditioner wind output through the air outlet of the air conditioner is fixed and single, the bundled wind has a strong sweeping feeling, and the comfort is poor. Moreover, the air outlet mode generally has periodicity, the mixing efficiency of the air is low, and the energy consumption is high. Summary of the Invention
[0005] The present invention solves at least one of the technical problems in the related art to a certain extent.
[0006] For this reason, the present application aims to provide an indoor air conditioner. The air conditioner wind flowing close to the first air outlet wall is the first air flow; the first air flow is divided into a second air flow and a third air flow after contacting the diversion port; because the diversion port is arc-shaped, the second air flow is guided into the diversion cavity. The third air flow is not guided by the diversion port and is directly output through the air outlet of the air conditioner. After the third air flow is output, because its flow rate is fast, under the Bernoulli effect, the indoor air will be driven to form a vortex outside the body.
[0007] The second air flow is output from the side of the diversion plate close to the heat exchange fan, and the flow direction of the second air flow is towards the second air outlet wall. Therefore, the second air flow will blow the first air flow to change the flow direction of the first air flow. Therefore, the first air flow will not blow to the diversion port to form the second air flow and the third air flow for a short time, so no vortex will be generated outside the body or the vortex speed will decrease. And because the second air flow is not formed, the first air flow will not be affected by the second air flow, and it will re-form the second air flow and the third air flow and repeat the above steps, so that the air conditioner wind output through the air outlet of the air conditioner is disturbed, and vortices are repeatedly formed outside the body many times. To achieve the disorder of the air conditioner wind, avoid the air conditioner wind blowing directly at the user for a long time, and improve the user experience.
[0008] In addition, the air deflector guides the air conditioner air so that when the air flow is output in a direction biased towards the second air outlet wall, the side of the air deflector close to the heat exchange fan is close to the flow splitter. Therefore, when the first air flow flows towards the air deflector, the air flow will be split into a fourth air flow, a fifth air flow, and a sixth air flow. The fourth air flow will directly enter the flow splitting chamber and be output through the side of the flow splitter away from the heat exchanger fan; the fifth air flow will contact the flow splitter and be guided out along the arc of the flow splitter, and the sixth air flow will contact the air deflector and be guided out by the air deflector. The output directions of the fourth air flow, the fifth air flow, and the sixth air flow are all towards the side biased towards the second air outlet wall, thereby achieving all-round air guiding.

[0025] Next, the present invention will be specifically described by way of exemplary embodiments. However, it should be understood that, without further recitation, the elements, structures, and features in one embodiment can also be beneficially incorporated into other embodiments. In this application, the air conditioner performs the refrigeration cycle of a wall-mounted air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, throttling, and evaporation, and supplies cold or heat to the air that has been conditioned and heat-exchanged. The compressor compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the refrigerant gas in a high-temperature and high-pressure state. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The expansion valve throttles the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure gas-liquid two-phase refrigerant.
[0026] In the evaporator, after the refrigerant expanded in the expansion valve absorbs heat and evaporates, it is in a low-temperature and low-pressure state, and then the refrigerant gas returns to the compressor. The evaporator can achieve a refrigeration effect by using the latent heat of vaporization of the refrigerant to perform a heat exchange with the material to be cooled.
[0027] The air conditioner includes an air conditioner indoor unit and an air conditioner outdoor unit, and the indoor unit includes a body. Throughout the cycle, the air conditioner indoor unit can adjust the temperature of the indoor space. The outdoor unit of the wall-mounted air conditioner refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger. The indoor unit of the wall-mounted air conditioner includes an indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger can be used as a condenser or an evaporator respectively. When the indoor heat exchanger is used as a condenser, the air conditioner indoor unit serves as a heater in the heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner indoor unit serves as a cooler in the cooling mode.
[0028] Hereinafter, the embodiments of the present application will be described in detail with reference to the accompanying drawings. As shown in the attached Figures 1 to 3 and Figures 7 to 13As shown, in a schematic embodiment of the air conditioner indoor unit 100 of the present invention, the air conditioner indoor unit 100 includes: a body, a heat exchange fan 200, a volute tongue, an indoor heat exchanger, an air conditioner air outlet, a wind deflector 300, a flow splitting chamber 700, a flow splitting plate 600, and a diversion opening 800; wherein, the heat exchange fan 200 is arranged inside the body; the indoor heat exchanger is arranged inside the body; under the action of the heat exchange fan 200, indoor air is heat-exchanged by the indoor heat exchanger and then output to the room.
[0029] The air conditioner air outlet is opened on the body; the two side walls in the width direction of the air conditioner air outlet are respectively a first air outlet wall 400 and a second air outlet wall 500; the second air outlet wall 500 is in an arc shape, and the opening of its center is directed towards the side away from the first air outlet wall 400; the first air outlet wall 400 is inclined from the side away from the heat exchange fan 200 towards the side away from the second air outlet wall 500; the wind deflector 300 is arranged at the air conditioner air outlet, and the wind deflector 300 is located between the first air outlet wall 400 and the second air outlet wall 500. The volute tongue is a part of the body, and the first air outlet wall 400 is connected to and tangent to the volute tongue.
[0030] The flow splitting chamber 700 is arranged on the side of the first air outlet wall 400 away from the heat exchange fan 200; the flow splitting plate 600 is arranged at the flow splitting chamber 700, the flow splitting plate 600 is in an arc shape and the opening is directed towards the second air outlet wall 500; the diversion opening 800 is opened on the side of the flow splitting chamber 700 away from the first air outlet wall 400; the inner wall of the diversion opening 800 is arranged in an arc shape and the opening is directed towards the flow splitting plate 600; wherein, the length directions of the first air outlet wall 400, the flow splitting plate 600, and the diversion opening 800 are the same as the length direction of the air conditioner air outlet.
[0031] As shown in the appendix Figures 1 to 3 and Figures 7 to 13 As shown, in addition, the present application also provides an air conditioner indoor unit 100, which includes: a body, a heat exchange fan 200, a volute tongue, an indoor heat exchanger, an air duct, a wind deflector 300, a flow splitting chamber 700, a flow splitting plate 600, and a diversion opening 800; wherein, the heat exchange fan 200 is arranged inside the body; the indoor heat exchanger is arranged inside the body; under the action of the heat exchange fan 200, indoor air is heat-exchanged by the indoor heat exchanger and then output to the room.
[0032] The air duct includes a first air outlet wall 400 and a second air outlet wall 500, and the first air outlet wall 400 and the second air outlet wall 500 form the air conditioner air outlet; the second air outlet wall 500 is in an arc shape, and the opening of its center is directed towards the side away from the first air outlet wall 400; the first air outlet wall 400 is inclined from the side away from the heat exchange fan 200 towards the side away from the second air outlet wall 500. The volute tongue is a part of the body, and the first air outlet wall 400 is connected to and tangent to the volute tongue.
[0033] The air deflector 300 is arranged at the air outlet of the air conditioner, and the air deflector 300 is located between the first air outlet wall 400 and the second air outlet wall 500; the flow dividing cavity 700 is arranged on the side of the first air outlet wall 400 away from the heat exchange fan 200; the flow dividing plate 600 is arranged at the flow dividing cavity 700, the flow dividing plate 600 is arc-shaped and the opening faces the second air outlet wall 500; the diversion port 800 is opened on the side of the flow dividing cavity 700 away from the first air outlet wall 400; the inner wall of the diversion port 800 is arranged in an arc surface and the opening faces the flow dividing plate 600.
[0034] Among them, the length directions of the first air outlet wall 400, the flow dividing plate 600 and the diversion port 800 are the same as the length direction of the air outlet of the air conditioner.
[0035] In this application, through the above scheme, the air flow of the air conditioner flowing close to the first air outlet wall 400 is the first air flow 900; after the first air flow 900 contacts the diversion port 800, it is separated into a second air flow 110 and a third air flow 120; because the inner wall of the diversion port 800 is in an arc surface, the second air flow 110 is guided into the flow dividing cavity 700. The third air flow 120 is not guided by the diversion port 800 and is directly output through the air outlet of the air conditioner. After the third air flow 120 is output, because its flow velocity is relatively fast, under the action of Bernoulli's principle, the indoor air will be driven to form a vortex outside the body of the air conditioner.
[0036] The second air flow 110 is output through the side of the flow dividing plate 600 close to the heat exchange fan 200, and the flow direction of the second air flow 110 faces the second air outlet wall 500. Therefore, the second air flow 110 will blow the first air flow 900 to change the flow direction of the first air flow 900. Therefore, the first air flow 900 will not blow to the diversion port 800 to form the second air flow 110 and the third air flow 120 for a short time, so no vortex will be generated outside the body of the air conditioner or the speed of the vortex will decrease. And because the second air flow 110 is not formed, the first air flow 900 will not be affected by the second air flow 110 either, and it will re-form the second air flow 110 and the third air flow 120 and repeat the above steps, so that the air flow of the air conditioner output through the air outlet of the air conditioner is disturbed, and vortices are repeatedly formed outside the body of the air conditioner for many times. To achieve the disorder of the air flow of the air conditioner, avoid the air flow of the air conditioner blowing directly at the user for a long time, and improve the user experience. And through the above scheme, the efficiency of air mixing is also improved, and energy consumption is saved.
[0037] In addition, the air deflector 300 guides the air of the air conditioner so that when the air flow outputs in a direction biased towards the second air outlet wall 500. The side of the air deflector 300 close to the heat exchange fan 200 is close to the flow dividing plate 600. Therefore, when the first air flow 900 flows towards the air deflector 300, the air flow will be divided into a fourth air flow 130, a fifth air flow 140, and a sixth air flow 150. The fourth air flow 130 will directly enter the flow dividing cavity 700 and be output through the side of the flow dividing plate 600 away from the heat generating fan; the fifth air flow 140 will contact the flow dividing plate 600 and be guided along the arc of the flow dividing plate 600 for output, and the sixth air flow 150 will contact the air deflector 300 and be guided by the air deflector 300 for output. The output directions of the fourth air flow 130, the fifth air flow 140, and the sixth air flow 150 are all towards the side biased towards the second air outlet wall 500, so as to achieve all-round air guiding.
[0038] Please refer to Figures 7 to 13 , in some embodiments, a first reference plane 160 is defined. The first reference plane 160 is tangent to the side of the first air outlet wall 400 close to the flow dividing cavity 700; the flow dividing plate 600 is located on the side of the first reference plane 160 away from the second air outlet wall 500. Through this design, it is ensured that the first air flow 900 flowing close to the first air outlet wall 400 will not be affected by the flow dividing plate 600 during output, and it is ensured that the first air flow 900 can contact the diversion port 800 and be divided by the diversion port 800 to form a second air flow 110 and a third air flow 120.
[0039] In some embodiments, the side of the flow dividing plate 600 close to the heat exchange fan 200 is the first flow dividing side 601, and the side away from the heat exchange fan 200 is the second flow dividing side 602. Both the first flow dividing side 601 and the second flow dividing side 602 are located on the side of the first reference plane 160 away from the second air outlet wall 500. To ensure that the flow dividing plate 600 is completely located on the side of the first reference plane 160 away from the second air outlet wall 500. Since the first reference plane 160 is the tangent plane of the side of the first air outlet wall 400 close to the flow dividing cavity 700, the output direction of the first air flow 900 output along the first air outlet wall 400 is within the first reference plane 160. By placing the first flow dividing plate 600 on the side of the first reference plane 160 away from the second air outlet wall 500, the first flow dividing plate 600 can be arranged on the side of the first air flow 900 away from the second air outlet wall 500, so that the first air flow 900 will not contact the flow dividing plate 600 during output, ensuring that the first air flow 900 will blow towards the diversion port 800.
[0040] In some embodiments, the first reference plane 160 intersects the diversion port 800. Through this design, it is ensured that the air conditioner air flowing close to the first air outlet wall 400 will contact the diversion port 800, and part of it will enter the flow dividing cavity 700 under the diversion of the diversion port 800.
[0041] Please refer to Figures 7 to 13, in some embodiments, one side of the diversion opening 800 close to the second air outlet wall 500 is the first diversion side 801, and the side away from the second air outlet wall 500 is the second diversion side 802; the first diversion side 801 and the second diversion side 802 are respectively located on both sides of the first reference plane 160. Since the first reference plane 160 is the tangent plane of the first air outlet wall 400 close to the diversion cavity 700, the output direction of the first air flow 900 output along the first air outlet wall 400 is within the first reference plane 160. Through the above design, it can be ensured that the output direction of the first air flow 900 is located between the first diversion side 801 and the second diversion side 802, that is, it is ensured that the first air flow 900 will contact the diversion opening 800 and be divided into a second air flow 110 and a third air flow 120 by the diversion opening 800.
[0042] In some embodiments, the distance from the second diversion side 602 to the first diversion side 801 is greater than the distance from the second diversion side 602 to the second diversion side 802. Through this solution, the flow rate entering the diversion opening 800 is increased, and the flow velocity of the second air flow 110 on the second diversion side 802 of the diversion opening 800 is increased, so that a relatively large impact velocity is generated by the second air flow 110 in the diversion cavity 700 at the first diversion side 601, disturbing the first air flow 900, so that the first air flow 900 is briefly blown towards the side biased towards the second air outlet wall 500.
[0043] Please refer to Figures 7 to 13 , in some embodiments, the depth direction of the air conditioner air outlet is the output direction of the air conditioner air, and the length direction of the air conditioner air outlet is the same as the length directions of the first air outlet wall 400, the second air outlet wall 500, the diversion cavity 700, the diversion plate 600, the diversion opening 800 and the air guide plate 300. The air guide plate 300 rotates along the rotation axis in the air conditioner air outlet, and the direction in which the air guide plate 300 guides the air flow out of the body is the air guiding direction. The air guiding direction of the air guide plate 300 is used to guide the air output through the air conditioner air outlet. A second reference plane 170 is defined, and the second reference plane 170 is tangent to the first diversion side 801; the angle between the second reference plane 170 and the width direction of the air guide plate 300 is between 0° and 90°, and this angle is α.
[0044] Through this design, when the air guide plate 300 is deflected so that the airflow is directed toward the direction of the second air outlet wall 500 for output. The side of the air guide plate 300 close to the heat exchange fan 200 is close to the diverter plate 600. Therefore, when the first airflow 900 flows toward the air guide plate 300, the airflow will be divided into the fourth airflow 130, the fifth airflow 140 and the sixth airflow 150; wherein, the fourth airflow 130 will directly enter the diverter cavity 700 from the first diverter side 601 and be output through the first guide side 801; the fifth airflow 140 will contact the diverter plate 600 and be guided along the curvature of the diverter plate 600 to be output from the second diverter side 602; the sixth airflow 150 will contact the air guide plate 300 and be guided by the air guide plate 300 for output. The output directions of the fourth airflow 130, the fifth airflow 140 and the sixth airflow 150 are all toward the side biased toward the second air outlet wall 500, thereby achieving all-round wind guidance.
[0045] In some embodiments, a plurality of air guide plates 300 are provided at intervals in the width direction of the air-conditioning outlet. The airflow output through the air-conditioning outlet is guided by the plurality of air guide plates 300. However, it is worth noting that when the air guide plate 300 is deflected so that the airflow is directed toward the direction of the second air outlet wall 500, only the air guide plate 300 closest to the first air outlet wall 400 will affect the first airflow 900. Moreover, the first airflow 900 is only a part of the air-conditioning wind output through the air-conditioning outlet, and does not represent all the air-conditioning wind.
[0046] In some embodiments, an air outlet grille is provided between the air guide plate 300 and the heat exchange fan 200. The air outlet of the air conditioner is blocked by the air outlet grille. Specifically, the two sides of the air outlet grille are respectively connected to the first air outlet wall 400 and the second air outlet wall 500. The air conditioning air is output through the holes on the air outlet grille. The air outlet grille is used to prevent external foreign matter from entering the interior of the machine body and protect the machine body.
[0047] Please refer to Figures 4 to 6 In the prior art, the air outlet of the air conditioner is opened at the front side of the machine body. When the air guide plate 300 is not used to guide and deflect the airflow, the width direction of the air guide plate 300 is parallel to the front of the machine body, that is, the air outlet direction of the air-conditioning air is toward the front of the machine body. At this time, the state of the air guide plate 300 is the initial state. However, due to the design reasons inside the machine body, the first air outlet wall 400 and the second air outlet wall 500 are not parallel to the front of the machine body, that is, as described above, the first air outlet wall 400 is inclined from the side away from the heat exchange fan 200 to the side away from the second air outlet wall 500. Therefore, when the air-conditioning air is output, the air outlet direction of the first air flow 900 close to the side of the first air outlet wall 400 will be along the setting direction of the first air outlet wall 400, that is, when the first air flow 900 is output, it will be inclined to the side away from the second air outlet wall 500.
[0048] Please refer to Figures 7 to 13, in this application, the air flow of the air conditioner includes the first air flow 900 which is the air flow close to the first air outlet wall 400, and the remaining air flow is the main air flow.
[0049] Through the setting of the diversion port 800, the first air flow 900 is divided into a second air flow 110 and a third air flow 120 after hitting the diversion port 800. The third air flow 120 is obliquely output in the direction of the second air outlet wall 500. And because it has hit the diversion port 800, the flow rate of the third air flow 120 is slower than that of the main air flow. The third air flow 120 is mixed with the main air flow, so that in the initial state, the air flow of the air conditioner output through the air outlet of the air conditioner is output in the front direction of the body.
[0050] Moreover, the third air flow 120 just passing through the air outlet of the air conditioner is inclined towards the second air outlet wall 500. Therefore, the indoor air will be driven by the third air flow 120. The principle is Bernoulli's principle. The flow rate of the indoor air is slow and the pressure is high, while the flow rate of the third air flow 120 is fast and the pressure is low. Under the action of the pressure, the indoor air flow approaches the third air flow 120. Then, the third air flow 120 is mixed with the main air flow. Because the flow rate of the main air flow is fast, it will blow the third air flow 120 and the indoor air flow to generate a vortex on the side of the main air flow far from the second air outlet wall 500, thus realizing the mixing of the indoor air and the air flow of the air conditioner and increasing the air volume.
[0051] At the same time as the above process occurs, the second air flow 110 flows through the diversion cavity 700 in the direction close to the first diversion side 601 and is output between the first diversion side 601 and the first air outlet wall 400. The second air flow 110 blows towards the first air flow 900 in the direction close to the second air outlet wall 500. Therefore, the first air flow 900 will deflect towards the side of the second air outlet wall 500. At this time, the first air flow 900 will not blow towards the diversion port 800, so the second air flow 110 and the third air flow 120 will not be formed. At this time, the vortex caused by the third air flow 120 in the room is stopped or decelerated. And because the second air flow 110 is not formed, the second air flow 110 in the diversion cavity 700 is interrupted, and the second air flow 110 cannot blow towards the first air flow 900 to change the direction of the first air flow 900. The first air flow 900 blows towards the diversion port 800 again and repeats the above actions.
[0052] Finally, the achieved effect is that the second air flow 110 repeatedly appears in the diversion cavity 700, the first air flow 900 is repeatedly guided, and the third air flow 120 outside is repeatedly formed. While correcting the deviation of the air flow of the air conditioner, disordered vortices are formed in the room to disrupt the normal output of the air flow of the air conditioner, so as to simulate the effect of natural wind, avoid the discomfort caused by the direct blowing of the air flow of the air conditioner on the user, and improve the user experience.
[0053] It should be noted that the reciprocating frequency of the above process is related to the flow rate of the air flow.
[0054] In addition, in the present application, when the air deflector 300 deflects to direct the air flow to output in the direction biased towards the second air outlet wall 500, the side of the air deflector 300 close to the first flow splitting side 601 approaches the flow splitting plate 600, and part of it blocks the air flow passing between the air deflector 300 and the flow splitting plate 600. When the first air flow 900 outputs, the air flow is split into a fourth air flow 130, a fifth air flow 140, and a sixth air flow 150 at the air deflector 300 and the first flow splitting side 601; among them, the fourth air flow 130 directly enters the flow splitting cavity 700 from the first flow splitting side 601 and is output through the first flow guiding side 801, and the output of the fourth air flow 130 is biased towards the second air outlet wall 500; The fifth air flow 140 and the sixth air flow 150 merge and impact the air deflector 300. The fifth air flow 140 and the sixth air flow 150 are split on the air deflector 300. The fifth air flow 140 flows towards the direction close to the flow splitting plate 600, and the sixth air flow 150 flows along the air deflector 300 in the direction away from the flow splitting plate 600 and merges with the main air flow for output. The fifth air flow 140 flows towards the flow splitting plate 600 and contacts the side of the flow splitting plate 600 facing the second air outlet wall 500. The fifth air flow 140 is guided along the arc of the flow splitting plate 600 and is output from the second flow splitting side 602, and its output direction is biased towards the second air outlet wall 500.
[0055] Because the output directions of the fourth air flow 130 and the fifth air flow 140 are biased towards the second air outlet wall 500, they will merge with the main air flow and be output, so as to realize that all the air flows of the air conditioner wind are output along the direction required by the user, improving the air volume and the user experience.
[0056] It should be noted that the solution in the present application is preferably applied to floor-standing air conditioners, but it is not limited to floor-standing air conditioners only. It can also be applied to other types of air conditioners such as wall-mounted air conditioners and duct machines.
