Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a top-outlet air conditioning outdoor unit. Background Art

[0002] A top-outlet outdoor unit is a common type of air conditioner outdoor unit. In a top-outlet air conditioner outdoor unit, the casing air outlet is opened at the top of the outdoor unit, the casing air inlet is arranged at the periphery of the outdoor unit, the heat exchanger is arranged along the height direction of the outdoor unit and extends along the inner peripheral wall of the outdoor unit, and the outdoor fan is located in the casing and arranged corresponding to the casing air inlet in the casing height direction. The operation of the outdoor fan generates negative pressure inside the casing, and the air outside the casing enters the casing through the casing air inlet, exchanges heat with the heat exchanger, and is output to the outside of the casing through the casing air outlet.

[0003] Since the outdoor fan is arranged near the top of the casing, the air induction effect of the outdoor fan on the air gradually weakens from top to bottom along the height direction of the casing inside the casing. The upper end of the heat exchanger is closer to the outdoor fan, so the air speed flowing through the upper end of the heat exchanger is fast, and the heat exchange effect of the upper end of the heat exchanger is good; while the bottom position of the heat exchanger is far away from the outdoor fan, so the air flow through the bottom of the heat exchanger is relatively poor, resulting in poor heat exchange effect at the bottom of the heat exchanger. In addition, in the design of the refrigeration system pipeline, when the heat exchanger is used as a condenser, the pipeline at the bottom of the heat exchanger is the last section through which the refrigerant flows in the entire condenser pipeline, so the temperature difference between the refrigerant in this pipeline and the outdoor air temperature is very small, which will also lead to poor heat exchange effect at the bottom of the heat exchanger. In the prior art, the heat exchange effect of the heat exchanger is uneven and cannot meet the requirements of the air conditioner outdoor unit well.

[0004] In view of this, this application is filed. Utility Model Content

The induced draft fan 900 operates to introduce the air at the bottom of the outdoor heat exchanger 600 into the air guide 800 from the air inlet of the air guide, and then the heat exchange fan 400 operates to output the air in the air guide 800 from the air outlet of the air guide through the air outlet 101 of the casing to the outside of the casing 100.

[0104] like Figure 4-Figure 6 As shown, the top-discharge air-conditioning outdoor unit includes a driving member 700, which is installed on the air guide member 800 and located at the upper end of the air guide member 800, and is used to drive the induced draft fan 900 to operate.

[0105] like Fig.11 and Fig.12 As shown, the driving member 700 includes a rotating member 710 , which is located in the accommodating chamber 610 and is used to drive the induced draft fan 900 to rotate.

[0106] The rotating member 710 is connected to the induced draft fan 900 , and the rotating member 710 and the induced draft fan 900 rotate along the same axis. The airflow in the casing 100 drives the rotating member 710 to rotate, so that the rotating member 710 drives the induced draft fan 900 to rotate synchronously, thereby realizing automatic rotation of the induced draft fan 900 .

[0107] Through the operation of the heat exchange fan 400, an airflow is formed inside the casing 100, flowing from the casing air inlet 102 to the casing air outlet 101. The rotating member 710 rotates under the action of the airflow and drives the induced draft fan 900 to rotate synchronously.

[0108] By operating the heat exchange fan 400, the airflow generated inside the casing 100 drives the rotating part 710 to rotate and drives the induced draft fan 900 to rotate synchronously, so that the induced draft fan 900 can be driven without power, that is, there is no need for a motor to drive the induced draft fan 900 to rotate, which can not only make full use of resources but also save resource waste.

[0109] like Figure 8 As shown, at least part of the rotating member 710 is located outside the air guide member 800, so that the rotating member 710 is in contact with the airflow in the housing 100, so that the airflow can drive the rotating member 710 to rotate.

[0110] It should be noted that the closer to the heat exchange fan 400, the stronger the air-inducing effect of the heat exchange fan 400 is, and the higher the air flow rate is. Therefore, in some embodiments, the rotating member 710 is installed at the upper end of the air guide member 800 so that the airflow can better drive the induced draft fan 900 to rotate.

[0111] Since the induced draft fan 900 is located inside the air guide member 800 , when the rotating member 710 is disposed at the upper end of the air guide member 800 , at least a portion of the rotating member 710 is located above the induced draft fan 900 .

[0112] The rotation axis of the rotating member 710 is arranged along the height direction of the housing 100 , and correspondingly, the rotation axis of the induced draft fan 900 is also arranged along the height direction of the housing 100 .

[0113] like Fig.11 and Fig.12 As shown, the rotating member 710 includes a hood 711, which is located on the top of the air guide member 800. The hood 711 is used to drive the induced draft fan 900 to rotate.

[0114] A cavity is defined inside the hood 711, and a hood opening is provided on the periphery of the hood 711, and the opening direction of the hood opening intersects with the direction of the normal line of the hood 711, so that the hood 711 rotates under the action of the lateral airflow; the hood opening is provided in plurality, and the plurality of hood openings are distributed along the circumference of the hood 711. It should be noted that the airflow driving the hood 711 to rotate belongs to the prior art in the art, and will not be described in detail here.

[0115] It should be noted that since the hood 711 is located at the upper end of the air guide member 800, and the air outlet of the air guide member is also arranged at the upper end of the air guide member 800, in order to prevent the hood 711 from blocking the air outlet of the air guide member, the hood opening on the periphery of the hood 711 is connected to the through cavity inside the air guide member 800, so that the air inside the air guide member 800 can flow out of the air guide member 800 through the hood opening.

[0116] like Fig.12 As shown, the rotating member 710 includes a connecting shaft 712, and the connecting shaft 712 is used to connect the hood 711 and the induced draft fan 900, and the connecting shaft 712 is arranged on the rotation axis of the induced draft fan 900. The hood 711 drives the induced draft fan 900 to rotate synchronously through the connecting shaft 712. It should be noted that the upper end of the connecting shaft 712 is arranged in the cavity and fixedly connected to the hood 711, and the lower end of the connecting shaft 712 is fixedly connected to the induced draft fan 900, so it can be known that at least part of the connecting shaft 712 is arranged in the internal cavity of the hood 711.

[0117] like Fig.11 and Fig.12 As shown, the driving member 700 includes a fixing member 720 for supporting the rotation of the rotating member 710 ; the fixing member 720 is installed on the air guide member 800 , and the rotating member 710 is connected to the fixing member 720 , and the rotating member 710 can rotate relative to the fixing member 720 .

[0118] The rotating member 710 is provided with a connecting portion 713 which is sleeved on the outer circumference of the fixing member 720 . When the rotating member 710 rotates, the connecting portion 713 slides relative to the fixing member 720 along the circumference of the fixing member 720 , so that the fixing member 720 supports the rotating member 710 to rotate.

[0119] like Fig.12 As shown, a through cavity is provided inside the fixing member 720, and the through cavity inside the fixing member 720 is interconnected with the through cavity inside the air guide member 800, and the through cavity inside the fixing member 720 is interconnected with the cavity of the wind cap 711 to achieve air circulation.

[0120] A support portion 721 is provided on the inner wall of the through cavity, and the connecting shaft 712 is arranged through the support portion 721 along the extension direction of the through cavity to support the rotation of the connecting shaft 712. When the connecting shaft 712 is deflected during the synchronous rotation of the connecting shaft 712 and the hood 711, the support portion 721 imposes constraints on the connecting shaft 712 to ensure that the connecting shaft 712 rotates reliably, and avoids the tilt of the rotation axis of the induced draft fan 900 caused by the tilt of the connecting shaft 712 during rotation, thereby causing the induced draft fan 900 to collide with the inner wall of the air guide 800.

[0121] The working principle of the top-outlet air-conditioning outdoor unit is as follows: through the operation of the heat exchange fan 400, an airflow is generated inside the casing 100 from the casing air inlet 102 to the casing air outlet 101. When the airflow flows through the hood 711, it drives the hood 711 to rotate, and the hood 711 drives the induced draft fan 900 to rotate synchronously through the connecting shaft 712. Through the operation of the induced draft fan 900, the air at the bottom of the outdoor heat exchanger 600 enters the air guide member 800 from the air guide member inlet and flows into the guide member 800. Air outlet of the air piece; due to the operation of the heat exchange fan 400, the air inside the casing 100 flows to the casing air outlet 101, and the air outlet of the air guide piece is close to the heat exchange fan 400. Therefore, the air flowing to the air outlet of the air guide piece flows to the casing air outlet 101 under the action of the heat exchange fan 400, and is output to the outside of the casing 100 from the casing air outlet 101. The air fluidity at the bottom of the outdoor heat exchanger 600 increases, and the heat exchange effect at the bottom of the outdoor heat exchanger 600 also increases accordingly.

[0122] like Fig.13 As shown, the flow path of the airflow in the above-mentioned top-outlet air-conditioning outdoor unit is as follows: under the operation of the heat exchange fan 400, the air outside the casing 100 enters the interior of the casing 100 through the casing air inlet 102 and flows to the casing air outlet 101; when the air flows to the casing air outlet 101, it drives the hood 711 to rotate, and after the hood 711 rotates, it drives the induced draft fan 900 to rotate synchronously. After the induced draft fan 900 rotates, the air located at the bottom of the outdoor heat exchanger 600 enters the interior of the air guide 800 through the air guide inlet and flows to the air guide outlet. The air flowing to the air guide outlet flows to the casing air outlet 101 again under the operation of the heat exchange fan 400, and is finally output to the outside of the casing 100 from the casing air outlet 101.

[0123] The above-mentioned top-outlet air-conditioning outdoor unit is configured by arranging an air guide member 800 in the accommodating cavity 610 defined by the outdoor heat exchanger 600, so that the lower end of the air guide member 800 is arranged close to the bottom of the outdoor heat exchanger 600, and the upper end of the air guide member 800 is arranged close to the heat exchange fan 400. The air at the bottom of the outdoor heat exchanger 600 is transported to a position close to the heat exchange fan 400 by utilizing the air guide member 800, so as to increase the fluidity of the air at the bottom of the outdoor heat exchanger 600, thereby increasing the heat exchange effect at the bottom of the outdoor heat exchanger 600.

[0124] The above-mentioned top-discharge air-conditioning outdoor unit utilizes the airflow generated inside the casing 100 when the heat exchange fan 400 is running to drive the rotating part 710 to rotate, so that the rotating part 710 drives the induced draft fan 900 to rotate synchronously. There is no need to set up a motor to drive the induced draft fan 900 to operate. It can not only simplify the overall structure and facilitate layout, but also save electricity and make full use of resources.
