Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and more specifically, to a fan frame structure and a cabinet air conditioner. Background Technology

[0002] Currently available air filter structures generally only have a single air supply function. When the air filter is used as an air outlet, the airflow can be directly discharged through the air filter. However, when the air filter is used as an air inlet, the airflow entering the air filter will directly exchange heat with the heat exchange components of the air conditioner when it is directly discharged into the air conditioner. This causes dust in the airflow to adhere to the surface of the heat exchange components, which, over time, affects the heat exchange efficiency of the heat exchange components.

[0003] Especially for cabinet air conditioners with 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 install filters at the air vents. This means that when the air vents are used as air inlets, the airflow entering the air conditioner from the outside cannot be effectively filtered. Summary of the Invention

[0004] This application provides a fan frame structure and a cabinet air conditioner. By providing side air vents on the outer periphery of the fan frame and a filter assembly around the side air vents, when the first air vent of the fan frame is closed, allowing air to enter the air cavity after being filtered through the side air vents and exit through the second air vent, the fan frame achieves a filtering effect when used as an air inlet. When the first air vent of the fan frame is open, allowing air to exit through the second air vent, the airflow can directly enter the air cavity and exit through the first air vent. Therefore, the fan frame structure provided in this application can be used as both an air outlet and an air inlet, and when used as an air inlet, it can effectively filter the incoming airflow to improve the intake effect. Specifically:

[0005] The first aspect of this application provides a windshield frame structure, the windshield frame structure comprising:

[0006] The ventilation frame has an internal ventilation cavity defined by the ventilation frame, a first air inlet and a second air inlet formed at both ends that communicate with the ventilation cavity, and a side air inlet formed on the outer periphery between the first air inlet and the second air inlet. One end of the side air inlet is connected to the ventilation cavity and the other end is connected to the external environment of the ventilation frame.

[0007] A filter assembly surrounds the outer perimeter of the air frame and covers the side air vents, used to filter the airflow passing through the side air vents.

[0008] When the first air vent is open, the air frame can function as an air outlet frame; when the first air vent is closed, the air frame can function as an air inlet frame. When the air frame functions as an air outlet frame, the airflow entering the air cavity through the second air vent can be discharged through the first air vent. When the air frame functions as an air inlet frame, the airflow outside the air frame can be filtered by the filter assembly and then enter the air cavity through the side air vent, and be discharged through the second air vent, thereby filtering the incoming airflow into the air frame.

[0009] In the above technical solution, the wind frame is designed as a cylindrical frame structure, and the first air inlet and the second air inlet are located on both sides of the height direction of the cylindrical wind frame.

[0010] The side air vents are provided in several groups, and these side air vents are designed in multiple groups from the first air vent side to the second air vent side.

[0013] In the above technical solution, multiple grille bars are designed to be inclined from the second air vent side to the first air vent side;

[0014] The inclined grille bars define the side air vents for inclined airflow between two adjacent grille bars.

[0015] In the above technical solution, the wind frame gradually extends from the second air outlet side to the first air outlet side;

[0016] The line connecting the extended ends of the grille strips that slope from the second air vent side to the first air vent side in the height direction of the air frame is adapted to the tapered shape of the air frame.

[0017] In the above technical solution, the filter assembly includes a filter support adapted to the shape of the air frame. The filter support has a hollow design and is fitted onto the outer periphery of the air frame. A filter guide rail is defined between the inner periphery of the filter support and the outer periphery of the air frame. The filter guide rail has a filter insertion port.

[0018] The filter assembly also includes a filter screen, which is inserted into the filter screen track through a filter screen insertion port and covers the side air vents on the outer periphery of the air frame.

[0019] A second aspect of this application provides a cabinet-type air conditioner, the air conditioner comprising:

[0020] The body has an upper air vent at the top, a lower air vent at the bottom, and an internal air supply duct connecting the upper and lower air vents; and

[0021] The fan assembly, located within the air supply duct, includes an upper fan assembly positioned near the upper air outlet and a lower fan assembly positioned near the lower air outlet; and

[0022] The heat exchanger assembly is located within the air supply duct, between the upper fan assembly and the lower fan assembly; and

[0023] The wind frame structure provided in the first aspect of the embodiments of this application;

[0024] The wind frame structure consists of two sets. One set is located between the upper wind inlet and the upper fan assembly, while the other set is located between the lower wind inlet and the lower fan assembly.

[0025] In the above technical solution, the first air outlet of the wind frame structure located between the wind outlet and the wind turbine assembly is set close to the wind outlet, and the second air outlet is set close to the wind turbine assembly.

[0026] The first air vent of the air frame structure located between the downwind vent and the downwind fan assembly is positioned close to the downwind vent, and the second air vent is positioned close to the downwind fan assembly.

[0027] In the above technical solution, both the upper fan assembly and the lower fan assembly are axial flow fan assemblies, and the air inlet and outlet directions of both the upper fan assembly and the lower fan assembly can be controlled and switched.

[0028] In the above technical solution, both the upper fan assembly and the lower fan assembly include an axial fan housing and axial fan blades disposed inside the axial fan housing.

[0029] The rotation direction of the axial flow fan blades can be controlled and changed, so that the air inlet and outlet directions of the fan can be switched by changing the rotation direction of the axial flow fan blades.

[0030] In the above technical solution, the axial fan blades of the upper fan assembly face upwards, and the axial fan blades of the lower fan assembly face downwards.

[0031] in

[0032] The axial fan blades of the aforementioned fan assembly discharge air downwards when rotating clockwise and upwards when rotating counterclockwise.

[0033] When the axial fan of the lower fan assembly rotates forward, it blows air upward; when it rotates in reverse, it blows air downward.

[0034] In the above technical solution, the heat exchanger assembly includes a V-shaped heat exchanger disposed between the upper fan assembly and the lower fan assembly;

[0035] The expanding end of the V-shaped heat exchanger faces the upper fan assembly, while the contracting section of the V-shaped heat exchanger faces the lower fan assembly.

[0036] In the above technical solutions, the air supply methods of the air conditioner include single-top air supply and single-bottom air supply.

[0037] in

[0039] When the air conditioner supplies air in a single downward air supply mode, both the upper fan assembly and the lower fan assembly are controlled to supply air downwards, and the first air vent of the lower air frame structure is controlled to open, while the first air vent of the upper air frame structure is controlled to close.

[0040] In the above technical solution, the air conditioner also includes:

[0041] A switching component, comprising a first switching component and a second switching component;

[0042] The upper air frame has a first on / off component at the first air vent, which is used to open or close the first air vent of the upper air frame. The lower air frame has a second on / off component at the first air vent, which is used to open or close the first air vent of the lower air frame.

[0043] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0044] In this embodiment, a side air vent is provided on the outer periphery of the air frame, and a filter screen assembly is provided on the outer periphery of the side air vent. In this way, when the first air vent of the air frame is closed and the air frame is used as an air inlet, the airflow outside the air frame can be filtered through the side air vent and enter the air cavity and be discharged through the second air vent, so as to achieve the airflow filtration effect when the air frame is used as an air inlet. When the first air vent of the air frame is opened and the air frame is used as an air outlet, the airflow can directly enter the air cavity through the second air vent and be discharged through the first air vent. That is, the air frame structure provided in this embodiment can be used as both an air outlet and an air inlet.

[0069] Background Introduction

[0070] Currently available air filter structures generally only have a single air supply function. When the air filter is used as an air outlet, the airflow can be directly discharged through the air filter. However, when the air filter is used as an air inlet, the airflow entering the air filter will directly exchange heat with the heat exchange components of the air conditioner when it is directly discharged into the air conditioner. This causes dust in the airflow to adhere to the surface of the heat exchange components, which, over time, affects the heat exchange efficiency of the heat exchange components.

[0071] Especially for cabinet air conditioners with 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 install filters at the air vents. This means that when the air vents are used as air inlets, the airflow entering the air conditioner from the outside cannot be effectively filtered.

[0072] Based on this, such as Figures 1-9 As shown, the first aspect of this application provides a windshield frame structure, the windshield frame structure 1000 including:

[0073] The ventilation frame 100 has an internal ventilation cavity defined by the ventilation frame 100, and a first air inlet 101 and a second air inlet 102 that communicate with the ventilation cavity are formed at both ends. A side air inlet 103 is formed on the outer periphery between the first air inlet and the second air inlet. One end of the side air inlet 103 is connected to the ventilation cavity and the other end is connected to the external environment of the ventilation frame 100.

[0074] A filter assembly 200 surrounds the outer periphery of the air frame 100 and covers the side air vent 103, and is used to filter the airflow passing through the side air vent 103.

[0075] When the first air vent 101 is open, the air frame 100 can be used as an air outlet frame, and when the first air vent 101 is closed, the air frame 100 can be used as an air inlet frame. When the air frame 100 is used as an air outlet frame, the airflow entering the air cavity through the second air vent 102 can be discharged through the first air vent 101. When the air frame 100 is used as an air inlet frame, the airflow outside the air frame can be filtered by the filter assembly 200 and then enter the air cavity through the side air vent 103, and be discharged through the second air vent 102, so as to filter the incoming airflow entering the air frame.

[0076] In this embodiment, a side air vent 103 is provided on the outer periphery of the air frame 100, and a filter assembly 200 is provided on the outer periphery of the side air vent 103. When the first air vent 101 of the air frame 100 is closed, allowing the air frame 100 to act as an air inlet, the airflow outside the air frame 100 can be filtered through the side air vent 103 and enter the air cavity, and then discharged through the second air vent 102. This achieves the airflow filtration effect when the air frame 100 acts as an air inlet. When the first air vent 101 of the air frame 100 is opened, allowing the air frame to act as an air outlet, the airflow can directly enter the air cavity through the second air vent 102 and be discharged through the first air vent 101. That is, the air frame structure 1000 provided in this embodiment can be used as both an air outlet and an air inlet. When the air frame 100 acts as an air inlet, it can also effectively filter the incoming airflow to improve the air intake effect.

[0077] Specifically, such as Figure 5 As shown, when the air frame structure 1000 is used as an air outlet frame, the airflow can enter through the second air vent 102 at its bottom and exit through the first air vent 101 at its top, as... Figure 6 As shown, when the air frame structure 1000 is used as an air inlet frame, the airflow can be filtered by the filter assembly 200 and enter the air cavity from the side air inlet 103, and then discharged through the second air inlet 102 at its bottom.

[0078] Furthermore, in some possible implementations, such as Figure 2 and Figure 3 As shown, the wind frame 100 is designed as a cylindrical frame structure, with the first air inlet 101 and the second air inlet 102 located on both sides of the cylindrical wind frame in the height direction.

[0079] The side air vents 103 are provided in several groups, and these side air vents 103 are designed in multiple groups from the first air vent side to the second air vent side. It is worth noting that the first air vent side refers to the side of the air frame where the first air vent 101 is located, and the second air vent side refers to the side of the air frame where the second air vent 102 is located.

[0080] In this embodiment of the application, by setting a number of side air vents 103 on the outer periphery of the air frame 100, the filtration effect of the incoming airflow can be improved while ensuring the air intake volume of the air frame 100.

[0081] Furthermore, in some possible implementations, such as Figure 2-Figure 3 As shown, the wind frame 100 is designed as a grid cylinder, which includes multiple grid strips 100a distributed from the first air outlet 101 side to the second air outlet 102 side;

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

[0083] In this embodiment, by setting the wind frame in the form of a grid tube, it is convenient to form the wind frame 100. On the other hand, by setting the wind frame in the form of a grid tube, the grid strips 100a can be used to guide the airflow to achieve the effect of guiding the airflow.

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

[0085] Among the multiple inclined grille bars 100a, an inclined side air outlet 103 is defined between two adjacent grille bars 100a.

[0086] In this embodiment, by designing the grille bar 100a to be inclined, the airflow entering the air cavity can be guided. Specifically, as shown... Figure 5 As shown, when the air frame structure 100 is used as an air outlet frame, the airflow entering the air cavity from the bottom second air inlet 102 can be guided by the grille strip 100a to the central area of ​​the air cavity, so as to improve the airflow volume of the air frame structure when it is used as an air outlet frame.

[0087] Furthermore, 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 line connecting the extended ends of the grille strip 100a, which is inclined from the second air vent 102 side to the first air vent 101 side, in the height direction of the air frame 100 is adapted to the tapered shape of the air frame 100.

[0089] In this embodiment, by setting the air frame 100 to a tapered shape and adjusting the grille strip 100a to fit the shape of the air frame 100a, the air delivery effect of the air frame 100 can be further improved.

[0090] Furthermore, in some possible implementations, such as Figure 4 As shown, the filter assembly 200 includes a filter support 201 adapted to the shape of the air frame 100. The filter support 201 has a hollow design and is fitted around the outer periphery of the air frame 100. A filter guide rail is defined between the inner periphery of the filter support 201 and the outer periphery of the air frame 100. The filter guide rail has a filter insertion port.

[0091] The filter assembly 200 also includes a filter screen (not shown in the figure), which is inserted into the filter screen track through the filter screen insertion port and covers the side air vents 103 on the outer periphery of the air frame 100.

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

[0093] Furthermore, a second aspect of the embodiments of this application also provides a cabinet-type air conditioner, such as... Figures 7-9 As shown, the air conditioner includes:

[0094] The body 300 has an upper air vent 301 at the top, a lower air vent 302 at the bottom, and an internal air supply duct connecting the upper air vent 301 and the lower air vent 302; and

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

[0096] A heat exchanger assembly 500 is installed in the air supply duct, and the heat exchanger assembly 500 is located 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 embodiments of this application;

[0098] The wind frame structure 1000 is provided in two sets. One set of wind frame structure 1000 is located between the upper wind outlet 301 and the upper fan assembly 401, and the other set of wind frame structure 1000 is located between the lower wind outlet 302 and the lower fan assembly 402.

[0099] The cabinet air conditioner provided in the second aspect of this application adopts the air frame structure provided in the first aspect of this application, which enables the air conditioner to effectively filter the airflow entering the air conditioner regardless of whether the air conditioner is in single-down air supply mode or single-up air supply mode.

[0100] Specifically, when the cabinet air conditioner supplies air in a single top-supply mode with air intake at the lower air vent 302 and air outlet at the upper air vent 301, the lower air frame structure 1000 can be used as an air intake frame and the lower air frame structure can be used as an air outlet frame. In this way, the airflow entering the air conditioner from the lower air vent 301 can be filtered by the filter assembly 200 of the lower air frame structure. After filtration, the airflow enters the air cavity of the air frame structure through the side air vent of the lower air frame structure and is discharged through the second air vent of the lower air frame structure to exchange heat with the heat exchanger assembly. The airflow after heat exchange passes directly through the second air vent 102 and the first air vent 101 of the upper air frame structure and is finally discharged into the room from the upper air vent 301 of the air conditioner, realizing the effect of lower air intake and upper air outlet of the cabinet air conditioner.

[0101] Similarly, when the cabinet air conditioner supplies air in the single-downward air supply mode with air intake at the upper air vent 301 and air outlet at the lower air vent 302, it is only necessary to use the upper air frame structure 1000 as the air intake frame and the lower air frame structure 1000 as the air outlet frame. The specific air supply principle is the same as described above for the single-upward air supply mode. The specific air supply distance of the single-downward air supply mode will not be elaborated in the embodiments of this application.

[0102] Furthermore, in some possible implementations, such as Figures 7-9 As shown, the first air vent 101 of the wind frame structure 1000 located between the upper air vent 301 and the upper air fan assembly 401 is set close to the upper air vent 301, and the second air vent 102 is set close to the upper air fan assembly 401.

[0103] The first air vent 101 of the air frame structure 1000 located between the downwind vent 302 and the downwind fan assembly 402 is positioned close to the downwind vent 302, and the second air vent 102 is positioned close to the downwind fan assembly 402.

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

[0105] Specifically, both the upper fan assembly 401 and the lower fan assembly 402 include an axial fan housing and axial fan blades disposed within the axial fan housing;

[0106] The rotation direction of the axial flow fan blades can be controlled and changed, so that the air 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 implementations, when it is necessary to switch the air outlet direction of the axial flow fan, the air inlet and outlet directions can also be switched by controlling the rotation of the entire axial flow fan assembly.

[0108] Furthermore, 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 this embodiment, by setting the heat exchanger assembly 500 into a V-shaped structure, the heat exchange effect between the airflow and the heat exchanger assembly 500 when the airflow flows from top to bottom or from bottom to top can be improved.

[0111] Furthermore, in some possible implementations, such as Figures 7-9 As shown, the air supply methods of air conditioners include single-top air supply and single-bottom air supply;

[0112] in

[0113] When the air conditioner supplies air in the single upward air supply mode, both the upper fan assembly 401 and the lower fan assembly 402 are controlled to supply air upward, and the first air vent 101 of the upper air frame structure is controlled to open, while the first air vent 101 of the lower air frame structure is controlled to close.

[0114] When the air conditioner supplies air in a single downward air supply mode, both the upper fan assembly 401 and the lower fan assembly 402 are controlled to supply air downwards, and the first air vent 101 of the lower air frame structure is controlled to open, while the first air vent 101 of the upper air frame structure is controlled to close.

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

[0116] The switching component 600 includes a first switching component 601 and a second switching component 602.

[0117] A first on / off component 601 is provided at the first air vent 101 of the upper air frame 100. The first on / off component 601 is used to open or close the first air vent 101 of the upper air frame 100. A second on / off component 602 is provided at the first air vent 101 of the lower air frame 100. The second on / off component 602 is used to open or close the first air vent 101 of the lower air frame 100.

[0118] Furthermore, in some possible implementations, such as Figures 7-9 As shown, the axial fan blades of the upper fan assembly 401 face upwards, and the axial fan blades of the lower fan assembly 402 face downwards.

[0119] in

[0120] The axial fan blades of the aforementioned fan assembly 401 discharge air downwards when rotating clockwise and upwards when rotating counterclockwise.

[0121] When the axial fan of the down fan assembly 402 rotates forward, it blows air upward; when it rotates in reverse, it blows air downward.

[0122] Specifically, when the air conditioner is turned on with single downward air outlet, the upper fan assembly 401 rotates forward and the lower fan assembly 402 rotates in reverse; when the air conditioner is turned on with single upward air outlet, the upper fan assembly 401 rotates in reverse and the lower fan assembly 402 rotates forward.

[0123] Specifically, when the air conditioner is in heating mode, it blows air out from the bottom. The upper fan assembly 401 rotates forward, and the lower fan assembly 402 rotates in reverse. This control of rotation direction allows the airflow at the top of the air conditioner to be quickly drawn into the air conditioner. Simultaneously, the first on / off component 602 at the top is closed, and the second on / off component 602 at the bottom is opened. Indoor airflow is drawn into the unit 300 from the upper air vent at the top of the air conditioner, then enters the air cavity of the air frame structure 1000 through the slanted grille, and sequentially passes downward through the upper fan assembly 401 and the V-shaped heat exchanger assembly 500. After heat exchange, it passes through the air cavity of the lower air frame structure 1000 and the lower air vent 302 into the room. Because hot air has a lower density, it rises and mixes with indoor air, causing the indoor temperature to quickly reach the set temperature. It is worth noting that when the air conditioner is set to heating mode and the fan speed is set to high, the upper fan assembly 401 and the lower fan assembly 402 will be turned on simultaneously. If the fan speed is not set to high, the lower fan assembly 402 will not be turned on.

[0124] More specifically, when the air conditioner is in cooling mode, it only blows air from the top. The lower fan assembly 402 rotates forward, and the upper fan assembly 402 rotates in reverse. This control of rotation direction allows airflow from the bottom of the air conditioner to be quickly drawn into the unit. Simultaneously, the lower second on / off assembly 602 is closed, and the upper first on / off assembly 601 is open. Indoor airflow is drawn into the unit 300 from the lower air vent 302 at the bottom of the air conditioner. It then enters the air cavity of the lower air frame structure 1000 through the slanted grille, and sequentially passes upward through the lower fan assembly 402 and the V-shaped heat exchanger assembly 500. After heat exchange, it passes through the air cavity of the upper air frame structure 1000 and the upper air vent 301 before entering the room. Due to the higher density of cold air, it sinks and mixes with indoor air, causing the indoor temperature to quickly reach the set temperature. It is worth noting that when the air conditioner is set to cooling or dehumidifying mode and the fan speed is set to high, the upper fan assembly 401 and the lower fan assembly 402 will be turned on simultaneously. When the fan speed is not set to high, the upper fan assembly 401 will not be turned on.
