Technical Field

[0002] At present, the existing wind frame structure generally only has a separate air supply function. When the wind frame is used as an air outlet frame, the airflow can be directly discharged through the wind frame, and when the wind frame is used as an air inlet frame, the airflow entering the wind frame is directly discharged into the air conditioner. Then, the untreated airflow will directly exchange heat with the heat exchange component of the air conditioner, causing dust in the airflow to adhere to the surface of the heat exchange component, which will affect the heat exchange effect of the heat exchange component in the long run.

Therefore, it is impossible to set a filter at the air vent position.

[0069] Background

[0070] At present, the existing wind frame structure generally only has a separate air supply function. When the wind frame is used as an air outlet frame, the airflow can be directly discharged through the wind frame, and when the wind frame is used as an air inlet frame, the airflow entering the wind frame is directly discharged into the air conditioner. Then, the untreated airflow will directly exchange heat with the heat exchange component of the air conditioner, causing dust in the airflow to adhere to the surface of the heat exchange component, which will affect the heat exchange effect of the heat exchange component in the long run.

[0071] Especially for cabinet air conditioners with up and down reversible air supply function, the air vents at the top and bottom of the cabinet air conditioner can be used as both air inlets and air outlets. Therefore, it is impossible to set a filter at the air vent position. This will result in the air flow entering the air conditioner from outside the air conditioner not being effectively filtered when the air vents are used as air inlets.

[0072] Based on this, Figure 1-Figure 9 As shown, a first aspect of an embodiment of the present application provides a wind frame structure, and the wind frame structure 1000 includes:

[0073] The wind frame 100 defines a wind cavity inside, has first and second wind ports 101 and 102 connected to the wind cavity at both ends, and has a side wind port 103 between the first and second wind ports at the periphery, one end of the side wind port 103 is connected to the wind cavity, and the other end is connected to the external environment of the wind frame 100;

[0074] The filter assembly 200 is disposed around the outer periphery of the wind frame 100 and covers the side air outlet 103, and is used to filter the airflow passing through the side air outlet 103;

[0075] The wind frame 100 can be used as an air outlet frame when the first air outlet 101 is opened, and can be used as an air inlet frame when the first air outlet 101 is closed; when the wind frame 100 is used as an air outlet frame, the airflow entering the air cavity through the second air outlet 102 can be discharged through the first air outlet 101, and when the wind frame 100 is used as an air inlet frame, the airflow outside the wind frame can enter the air cavity through the side air outlet 103 after being filtered by the filter assembly 200, and be discharged through the second air outlet 102, so as to filter the intake airflow entering the wind frame.

[0076] In the embodiment of the present application, a side air outlet 103 is provided on the outer peripheral side of the air frame 100, and a filter assembly 200 is provided on the outer periphery of the side air outlet 103. In this way, when the first air outlet 101 of the air frame 100 is closed and the air frame 100 is used as an air inlet frame to take in air, the airflow outside the air frame 100 can enter the air cavity after being filtered through the side air outlet 103 and be discharged through the second air outlet 102, so as to achieve the filtering effect of the airflow when the air frame 100 is used as an air inlet frame. When the first air outlet 101 of the air frame 100 is opened and the air frame is used as an air outlet frame to discharge air, the airflow can directly enter the air cavity through the second air outlet 102 and be discharged through the first air outlet 101. That is, the air frame structure 1000 provided in the embodiment of the present application can be used as both an air outlet frame and an air inlet frame, and the air frame 100 can also effectively filter the intake air flow when taking in air as an air inlet frame, so as to improve the intake effect of the intake air flow.

[0077] Specifically, Figure 5 As shown, when the wind frame structure 1000 is used as an air outlet frame to discharge air, the air flow can enter through the second air outlet 102 at the bottom and be discharged through the first air outlet 101 at the top, as shown in FIG. Figure 6 As shown, when the wind frame structure 1000 is used as an air inlet frame to take in air, the airflow can enter the air cavity from the side air outlet 103 after being filtered by the filter assembly 200, and be discharged through the second air outlet 102 at the bottom thereof.

[0078] Further, in some possible implementations, such as Figure 2 and Figure 3 As shown, the wind frame 100 is designed as a cylindrical frame structure, and the first air outlet 101 and the second air outlet 102 are arranged on both sides of the height direction of the cylindrical wind frame;

[0079] There are several side vents 103, which are designed into multiple groups from the first vent side to the second vent side. It is worth noting that the first vent side refers to the side of the wind frame where the first vent 101 is located, and the second vent side refers to the side of the wind frame where the second vent 102 is located.

[0080] In the embodiment of the present application, by providing a plurality of side air ports 103 on the outer periphery of the wind frame 100 , it is possible to improve the filtering effect of the intake airflow while ensuring the intake air volume of the wind frame 100 .

[0081] Further, in some possible implementations, such as Figure 2-Figure 3 As shown, the wind frame 100 is designed as a grille tube, and the grille tube includes a plurality of grille bars 100a distributed from the first air outlet 101 side to the second air outlet 102 side;

[0082] A side air outlet 103 is defined between two adjacent grille bars 100a.

[0083] In the embodiment of the present application, by setting the wind frame in the form of a grille tube, on the one hand, it is convenient to form the wind frame 100, and on the other hand, by setting the wind frame in the form of a grille tube, the grille bars 100a can be used to guide the airflow to achieve the airflow guidance effect.

[0084] Specifically, in some possible implementations, such as Figure 2 and Figure 3 As shown, the plurality of grille bars 100a are designed to be inclined from the second air outlet 102 side to the first air outlet 101 side;

[0085] A side air outlet 103 for inclined air discharge is defined between two adjacent grille bars 100a among the plurality of grille bars 100a arranged obliquely.

[0086] In the embodiment of the present application, the grille bars 100a are designed to be inclined, so that the airflow entering the air cavity can be guided. Figure 5 As shown, when the wind frame structure 100 is used as an air outlet frame to discharge air, the airflow entering the air cavity from the second air outlet 102 at the bottom can be guided to the central area of ​​the air cavity by the grille bars 100a to increase the air volume of the wind frame structure as an air outlet frame.

[0087] Further, in some possible implementations, the wind frame 100 gradually extends from the second air outlet 102 side to the first air outlet 101 side;

[0088] The connecting line of the extended ends of the grille bars 100 a inclined from the second air outlet 102 side to the first air outlet 101 side in the height direction of the wind frame 100 is adapted to the tapered shape of the wind frame 100 .

[0089] In the embodiment of the present application, the air frame 100 is configured to be tapered, and the grille bars 100a are also configured to be inclined to match the shape of the air frame 100a, so that the air supply effect of the air frame 100 can be further improved.

[0090] Further, in some possible implementations, such as Figure 4 As shown, the filter assembly 200 includes a filter bracket 201 adapted to the shape of the wind frame 100, the filter bracket 201 is hollowed out and sleeved on the outer periphery of the wind frame 100, and a filter guide rail is defined between the inner periphery of the filter bracket 201 and the outer periphery of the wind frame 100; the filter guide rail has a filter insertion port;

[0091] The filter assembly 200 further includes a filter {not shown in the figure}, which is inserted into the filter track through a filter insertion port and covers the side air outlet 103 on the outer peripheral side of the wind frame 100 .

[0092] Specifically, the wind frame 100 is inserted into the filter bracket 201, and a filter guide rail is formed between the two parts. After the filter is inserted, it goes around the outside of the wind frame in the filter guide rail to fully cover the side air outlets on the outer periphery of the wind frame 100.

[0093] Furthermore, the second aspect of the embodiment of the present application also provides a cabinet air conditioner, such as Figure 7-Figure 9 As shown, the air conditioner includes:

[0094] A machine body 300, wherein the top of the machine body 300 is provided with an upper air outlet 301, the bottom of the machine body 300 is provided with a lower air outlet 302, and an air supply duct connecting the upper air outlet 301 and the lower air outlet 302 is provided inside the machine body 300; and

[0095] A fan assembly 400 disposed in the air supply duct, the fan assembly 400 comprising an upper fan assembly 401 disposed near the upper air outlet 301 and a lower fan assembly 402 disposed near the lower air outlet 302; and

[0096] A heat exchanger assembly 500 disposed in the air supply duct, wherein the heat exchanger assembly 500 is disposed between the upper fan assembly 401 and the lower fan assembly 402; and

[0097] The wind frame structure 1000 provided in the first aspect of the embodiment of the present application;

[0098] There are two groups of wind frame structures 1000 , one group of wind frame structures 1000 is arranged between the upper air outlet 301 and the upper fan assembly 401 , and the other group of wind frame structures 1000 is arranged between the lower air outlet 302 and the lower fan assembly 402 .

[0099] The cabinet air conditioner provided in the second aspect of the embodiment of the present application adopts the wind frame structure provided in the first aspect of the embodiment of the present application, so that the air flow entering the air conditioner can be effectively filtered regardless of whether the air conditioner is in a single downward air supply mode or a single upward air supply mode.

[0100] Specifically, when the cabinet air conditioner supplies air in a single upward air supply mode with air intake through the lower air outlet 302 and air outlet through the upper air outlet 301, the wind frame structure 1000 located below can be used as an air inlet frame, and the wind frame structure located below can be used as an air outlet frame, so that the airflow entering the interior of the air conditioner from the lower air outlet 301 can be filtered by the filter mesh assembly 200 of the lower wind frame structure, and after filtering, enters the wind cavity of the wind frame structure through the side air outlet of the lower wind frame structure, and is discharged through the second air outlet of the lower wind frame structure to exchange heat with the heat exchanger assembly, and the airflow after heat exchange directly passes through the second air outlet 102 and the first air outlet 101 of the upper wind frame structure, and is finally discharged into the room from the upper air outlet 301 of the air conditioner, thereby realizing the downward air intake and upward air outlet effect of the cabinet air conditioner.

[0101] Similarly, when the cabinet air conditioner supplies air in the single downward air supply mode with the upper air outlet 301 taking in air and the lower air outlet 302 exhausting air, it is only necessary to use the wind frame structure 1000 located above as the air inlet frame and the wind frame structure 1000 located below as the air outlet frame. The specific air supply principle refers to the above description of the single upward air supply mode, and the specific air supply distance of the single downward air supply mode is not elaborated in the embodiment of the present application.

[0102] Further, in some possible implementations, such as Figure 7-Figure 9 As shown, the first air outlet 101 of the wind frame structure 1000 located between the upper air outlet 301 and the upper fan assembly 401 is arranged close to the upper air outlet 301, and the second air outlet 102 is arranged close to the upper fan assembly 401;

[0103] The first air outlet 101 of the wind frame structure 1000 located between the lower air outlet 302 and the lower fan assembly 402 is arranged close to the lower air outlet 302 , and the second air outlet 102 is arranged close to the lower fan assembly 402 .

[0104] Further, in some possible implementations, such as Figure 7-Figure 9 As shown, the upper fan assembly 401 and the lower fan assembly 402 are both axial flow fan assemblies, and the air inlet and outlet directions of the upper fan assembly 401 and the lower fan assembly 402 can be controlled and switched.

[0105] Specifically, the upper fan assembly 401 and the lower fan assembly 402 each include an axial flow fan casing and axial flow fan blades disposed in the axial flow fan casing;

[0106] The rotation direction of the axial flow fan blades can be controlled and changed, so that the inlet and outlet directions of the fan can be switched by changing the rotation direction of the axial flow fan blades.

[0107] Of course, in some alternative embodiments, when the air outlet direction of the axial flow fan needs to be switched, the switching of the air inlet and outlet directions can also be achieved by controlling the flipping of the entire axial flow fan assembly.

[0108] Further, in some possible implementations, the heat exchanger assembly 500 includes a V-shaped heat exchanger disposed between the upper fan assembly 401 and the lower fan assembly 402;

[0109] The expanding end of the V-shaped heat exchanger faces the upper fan assembly 401 , and the contracting section of the V-shaped heat exchanger faces the lower fan assembly 402 .

[0110] In the embodiment of the present application, by configuring the heat exchanger assembly 500 to be a V-shaped structure, the heat exchange effect between the airflow and the heat exchanger assembly 500 can be improved when the airflow flows from top to bottom or from bottom to top.

[0111] Further, in some possible implementations, such as Figure 7-Figure 9 As shown, the air supply mode of the air conditioner includes a single upper air supply mode and a single lower air supply mode;

[0112] in

[0113] When the air conditioner supplies air in a single upward air supply mode, the upper fan assembly 401 and the lower fan assembly 402 are both controlled to discharge air upward, and the first air outlet 101 of the upper wind frame structure is controlled to be opened, and the first air outlet 101 of the lower wind frame structure is controlled to be closed;

[0114] When the air conditioner supplies air in a single downward air supply mode, the upper fan assembly 401 and the lower fan assembly 402 are both controlled to discharge air downward, and the first air outlet 101 of the wind frame structure located at the bottom is controlled to be opened, and the first air outlet 101 of the wind frame structure located at the top is controlled to be closed.

[0115] Furthermore, in some possible implementations, the air conditioner further includes:

[0116] The switch component 600 includes a first switch component 601 and a second switch component 602;

[0117] A first on-off component 601 is provided at the first air outlet 101 of the upper wind frame 100, and the first on-off component 601 is used to open or close the first air outlet 101 of the upper wind frame 100. A second on-off component 602 is provided at the first air outlet 101 of the lower wind frame 100, and the second on-off component 602 is used to open or close the first air outlet 101 of the lower wind frame 100.

[0118] Further, in some possible implementations, such as Figure 7-Figure 9 As shown, the axial flow blades of the upper fan assembly 401 face upward, and the axial flow blades of the lower fan assembly 402 face downward;

[0119] in

[0120] The axial flow blades of the upper fan assembly 401 discharge air downward when rotating forward, and discharge air upward when rotating reversely;

[0121] The axial flow fan of the lower fan assembly 402 blows air upward when rotating forward, and blows air downward when rotating reversely.

[0122] Specifically, when the air conditioner is turned on for single down-flow air outlet, the upper fan assembly 401 rotates forward and the lower fan assembly 402 rotates reversely; when the air conditioner is turned on for single up-flow air outlet, the upper fan assembly 401 rotates reversely and the lower fan assembly 402 rotates forward.

[0123] Specifically, when the air conditioner is turned on in heating mode, the air conditioner only blows out from the bottom, the upper fan assembly 401 rotates forward, and the lower fan assembly 402 rotates reversely. The control of the rotation direction can make the airflow at the top of the air conditioner be quickly sucked into the inside of the air conditioner, and at the same time, the first on-off assembly 602 located at the top is closed, and the second on-off assembly 602 located at the bottom is opened. The indoor airflow is sucked into the body 300 from the upper air outlet at the top of the air conditioner, and then enters the air cavity of the air frame structure 1000 from the oblique grille of the upper air frame structure 1000, and passes downward through the upper fan assembly 401 and the V-shaped heat exchanger assembly 500 in turn, and enters the room through the air cavity of the lower air frame structure 1000 and the lower air outlet 302 after heat exchange. Since the hot air has a low density, it floats up and mixes with the indoor air in the room, so that the indoor temperature quickly reaches the set temperature. It is worth noting that when the air conditioner is set to heating mode and the operating windshield is at a super-strong wind speed, the upper fan assembly 401 and the lower fan assembly 402 are turned on at the same time. If the operating windshield is not a super-strong windshield, the lower fan assembly 402 is not turned on.

[0124] More specifically, when the air conditioner is in cooling mode, the air conditioner only discharges air from the upper part, the lower fan assembly 402 rotates forward, and the upper fan assembly 402 rotates reversely. The control of the rotation direction can make the airflow at the bottom of the air conditioner be quickly sucked into the air conditioner, and at the same time, the second on-off assembly 602 located at the bottom is closed, and the first on-off assembly 601 located at the top is opened. The indoor airflow is sucked into the body 300 from the lower air outlet 302 at the bottom of the air conditioner, and enters the air cavity of the lower air frame structure 1000 from the oblique grille of the lower air frame structure 1000, and passes through the lower fan assembly 402 and the V-shaped heat exchanger assembly 500 upward in sequence, and enters the room through the air cavity of the upper air frame structure 1000 and the upper air outlet 301 after heat exchange. Due to the large density of cold air, it sinks indoors and mixes with the indoor air, so that the indoor temperature quickly reaches the set temperature. It is worth noting that when the air conditioner is set to cooling or dehumidification mode and the operating windshield is at a super-strong wind speed, the upper fan assembly 401 and the lower fan assembly 402 are turned on at the same time. When the operating windshield is not at a super-strong wind speed, the upper fan assembly 401 is controlled not to be turned on.
