A cabinet type air conditioner

Abstract

The application provides a cabinet type air conditioner, and belongs to the field of air conditioners. A new air module of the air conditioner is communicated with a machine body shell passage. When new air is introduced, the new air can enter into an air duct component through the machine body shell passage, so that the new air can follow the air duct component to switch the air supply path to achieve the air supply effect of different positions. Meanwhile, the air inlet of the air conditioner can be controlled to be opened or closed. In this way, when the air inlet is closed, the new air module can be used as the air inlet of the air conditioner to provide air volume for the air conditioner, so that an independent new air supply mode is realized. When the air inlet is opened, the new air module can also provide the air inlet for the whole air conditioner, so that a mixed new air supply mode with large air volume is realized.

Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more particularly to a cabinet-type air conditioner. Background Technology

[0002] The fresh air function of existing air conditioners mainly draws fresh outdoor air into the room to improve indoor air quality.

[0003] There are three types of fresh air outlets in existing air conditioners. One type is to directly exhaust the fresh air into the room through the air outlet on the air inlet casing. Another type is to set the fresh air outlet at the main air outlet of the air conditioner and blow the fresh air away with the help of the main fan. This type is mainly used in cross-flow fans. The third type is to place the fresh air outlet near the air inlet side of the evaporator component and blow it out after heat exchange in the evaporator.

[0004] All three fresh air outlet methods are applied to air conditioners with rear air intake. On the one hand, the fresh air outlet method and location cannot change with changes in indoor air quality. On the other hand, the fresh air only serves as a fresh air function and cannot increase the air volume of the air conditioner. Summary of the Invention

[0005] To overcome the problems in related technologies where the air outlet mode and location of fresh air cannot change with changes in indoor air quality, and where the fresh air module can only function as a fresh air unit without increasing air volume, this invention proposes an air conditioner with a fresh air function and reversible air supply and return. The fresh air module is connected to the air conditioner's casing channel. When fresh air is introduced, it enters the ductwork component through the casing channel, thus following the ductwork component's air supply path to achieve fresh air supply at different locations. Simultaneously, the air inlet of the air conditioner can be controlled to open or close. When the inlet is closed, the fresh air module acts as the air inlet, providing air volume to the air conditioner, thus achieving an independent fresh air supply mode. When the inlet is open, the fresh air module can also provide air volume to the entire air conditioner, thus achieving a large-volume mixed fresh air supply mode.

[0006] This invention provides a cabinet-type air conditioner, comprising:

[0007] The casing has an upper air vent at the top and a lower air vent at the bottom.

[0008] The air duct component is located inside the housing and defines a channel between the air duct component and the housing. The top of the air duct component is provided with an upper air duct opening that connects to the upper air vent, and the bottom is provided with a lower air duct opening that connects to the lower air vent.

[0009] The flow path control mechanism is used to control the air duct components to form different air supply paths. The air supply paths of the air duct components include a single downward air supply path with air entering from the fuselage housing channel and exiting from the lower air outlet, a single upward air supply path with air entering from the fuselage housing channel and exiting from the upper air outlet, and a dual air supply path with air entering from the fuselage housing channel and exiting from both the upper and lower air outlets simultaneously.

[0010] The fresh air module has an air inlet and an exhaust end. The air inlet is used to connect to the outdoor environment, and the exhaust end is connected to the casing channel. The fresh air module can introduce outdoor fresh air into the casing channel when the air duct component delivers air through different air delivery paths.

[0011] The unit is also equipped with an air inlet that connects to the main body casing channel. The air inlet can be controlled to open or close, so that when outdoor fresh air is introduced into the main body casing channel, the external airflow of the air conditioner can be selectively introduced through the air inlet to mix with the fresh air, so that the air conditioner has different fresh air outlet modes.

[0012] In the above technical solution, the air inlet includes an upper air inlet located at the top of the casing and / or a lower air inlet located at the bottom of the casing.

[0013] In the above technical solution, the cabinet air conditioner has a front side facing the user when installed, and a rear side opposite to the front side;

[0014] The lower air vent is located at the bottom front of the air conditioner, while the fresh air module is located at the bottom rear of the air conditioner.

[0015] In the above technical solution, the air duct component has an upper air supply duct, an upper fan duct, an intermediate air duct, a lower fan duct, and a lower air supply duct arranged sequentially and connected to each other. The upper part of the upper air supply duct is connected to the upper air outlet, and the lower part of the lower air supply duct is connected to the lower air outlet.

[0016] The flow path control mechanism includes an upper flow path control mechanism and a lower flow path control mechanism installed on the air duct component;

[0017] The upstream flow control mechanism can connect the upstream fan duct and the upstream air supply duct while simultaneously blocking the connection between the upstream fan duct and the intermediate air duct. The upstream flow control mechanism can also block the upstream fan duct and the upstream air supply duct while simultaneously connecting the upstream fan duct and the intermediate air duct.

[0018] The downstream flow control mechanism can connect the downstream fan duct and the downstream air supply duct while simultaneously blocking the connection between the downstream fan duct and the intermediate air duct. The downstream flow control mechanism can also block the downstream fan duct and the downstream air supply duct while simultaneously connecting the downstream fan duct and the intermediate air duct.

[0019] In the above technical solution, the upper flow path control mechanism can also connect the upper fan duct and the upper air supply duct at the same time, and the upper flow path control mechanism can also block the connection between the upper air supply duct and the middle air duct at the same time.

[0020] The downstream flow control mechanism can also connect the downstream fan duct and the downstream air supply duct while simultaneously connecting the downstream air supply duct and the intermediate air supply duct. Furthermore, the downstream flow control mechanism can also block the connection between the downstream air supply duct and the intermediate air supply duct while simultaneously blocking the connection between the downstream fan duct and the downstream air supply duct.

[0021] In the above technical solution, the upwind and downwind vents can be controlled to open or close.

[0022] The upper air supply duct has an upper return air inlet on its duct wall that connects the fuselage casing and the upper air duct, and the lower air supply duct has a lower return air inlet on its duct wall that connects the fuselage casing and the lower air duct.

[0023] The upper flow path control mechanism can close the upper return air outlet while connecting the upper air supply duct and the upper fan duct, and open the upper return air outlet when blocking the connection between the upper air supply duct and the upper fan duct;

[0024] The downflow control mechanism can close the downflow return air outlet while connecting the downflow air duct and the downflow fan duct, and open the downflow return air outlet when blocking the connection between the downflow air duct and the downflow fan duct.

[0025] In the above technical solution, the cabinet air conditioner also includes an upper fan installed in the upper fan duct and a lower fan installed in the lower fan duct.

[0026] The upper air supply duct has an upper air supply duct A side close to the upper fan side and an upper air supply duct B side close to the upper air outlet side. The upper air supply duct includes a first upper air supply duct and a second upper air supply duct that are separated on the upper air supply duct A side and connected on the upper air supply duct B side.

[0027] The downflow duct has a downflow duct A side near the downflow fan and a downflow duct B side near the downflow outlet. The downflow duct includes a first downflow duct and a second downflow duct that are separated on the downflow duct A side and connected on the downflow duct B side.

[0028] The upper flow path control mechanism includes an upper baffle mechanism rotatably disposed at the connection position between the upper fan duct and the first upper supply air duct, and an upper volute mechanism capable of circumferentially sliding around a preset rotation axis of the upper fan. The upper baffle mechanism has a first upper rotation position and a second upper rotation position when rotating, and the upper volute mechanism has a first upper sliding position and a second upper sliding position when sliding. When the upper baffle mechanism is in the first upper rotation position, the upper return air inlet is opened while blocking the connection between the upper fan duct and the first upper supply air duct. When the upper baffle mechanism is in the second upper rotation position, the upper return air inlet is closed while connecting the upper fan duct and the first upper supply air duct. When the upper volute mechanism is in the first upper sliding position, the upper fan duct maintains connection with the intermediate air duct while blocking the connection between the upper fan duct and the second upper supply air duct. When the upper volute mechanism is in the second upper sliding position, the upper fan duct connects with the second upper supply air duct while blocking the connection between the upper fan duct and the intermediate air duct.

[0029] The downstream flow control mechanism includes a lower baffle mechanism rotatably positioned at the connection point between the downstream fan duct and the first downstream air supply duct, and a lower volute mechanism capable of circumferentially sliding around a preset rotation axis of the downstream fan. The lower baffle mechanism has a first lower rotation position and a second lower rotation position when rotating, and the lower volute mechanism has a first lower sliding position and a second lower sliding position when sliding. When the lower baffle mechanism is in the first lower rotation position, the downstream return air inlet is opened while simultaneously blocking the connection between the downstream fan duct and the first downstream air supply duct. When the lower baffle mechanism is in the second lower rotation position, the downstream return air inlet is closed while simultaneously connecting the downstream fan duct and the first downstream air supply duct. When the lower volute mechanism is in the first lower sliding position, the downstream fan duct remains connected to the intermediate air supply duct while simultaneously blocking the connection between the downstream fan duct and the second downstream air supply duct. When the lower volute mechanism is in the second sliding position, the downstream fan duct connects to the second downstream air supply duct while simultaneously blocking the connection between the downstream fan duct and the intermediate air supply duct.

[0030] In the above technical solution, the upper fan and the lower fan are centrifugal fans, and the upper fan and the lower fan rotate in opposite directions.

[0031] In the above technical solution, the cabinet air conditioner also includes:

[0032] The heat exchange component includes an upper heat exchange section and a lower heat exchange section disposed in the housing channel of the fuselage. The upper heat exchange section is opposite to the axial air inlet of the upper fan, and the lower heat exchange section is opposite to the axial air inlet of the lower fan.

[0033] In the above technical solution, the upper fan and the lower fan are double-suction centrifugal fans that can be inhaled from both sides of the axial direction. The heat exchange component, which is composed of the upper heat exchange section and the lower heat exchange section, is constructed as a V-shaped heat exchange component with the notch facing the air inlet of the centrifugal fan.

[0034] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0035] This invention proposes an air conditioner with a fresh air function and reversible air supply and return. The fresh air module is connected to the air conditioner's casing channel. When fresh air is introduced, it can enter the air duct component through the casing channel and switch with the air supply path of the air duct component to achieve fresh air supply effect at different locations. At the same time, the air inlet of the air conditioner can be controlled to open or close. When the air inlet is closed, the fresh air module can act as the air inlet of the air conditioner to provide air volume, thereby realizing an independent fresh air supply mode. When the air inlet is opened, the fresh air module can also provide air volume for the entire air conditioner, thereby realizing a large-volume mixed fresh air supply mode.

[0061] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0062] Current air conditioners have several drawbacks when introducing fresh air. First, the air outlet method and location cannot change with variations in indoor air quality. Second, the fresh air module can only function as a fresh air unit and cannot increase the overall airflow. To address these issues, this invention proposes an air conditioner with a fresh air function and reversible air supply and return. The fresh air module is connected to the air conditioner's casing. When fresh air is introduced, it enters the ductwork through the casing and follows the ductwork's airflow path to achieve different locations of fresh air delivery. Simultaneously, the air inlet can be controlled to open or close. When the inlet is closed, the fresh air module acts as the air conditioner's intake, providing airflow for an independent fresh air delivery mode. When the inlet is open, the fresh air module also provides airflow to the entire air conditioner, achieving a high-volume mixed fresh air delivery mode.

[0063] The following is in conjunction with the appendix Figure 1 - Appendix Figure 14 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0064] Example

[0065] like Figures 1-14 As shown, this embodiment proposes a cabinet-type air conditioner, including:

[0066] The housing 1 has an upper air vent 11 at the top and a lower air vent 12 at the bottom.

[0067] Air duct component 2 is located inside the housing 1 and defines the housing channel 3 between the housing 1 and the housing 1. The top of the air duct component 2 is provided with an upper air duct opening 21 that connects to the upper air vent 11, and the bottom is provided with a lower air duct opening 22 that connects to the lower air vent 12.

[0068] The flow path control mechanism is used to control the air duct component 2 to form different air supply paths. The air supply paths of the air duct component 2 include a single downward air supply path with air entering from the fuselage housing channel 3 and exiting from the lower air outlet 22, a single upward air supply path with air entering from the fuselage housing channel 3 and exiting from the upper air outlet 21, and a dual air supply path with air entering from the fuselage housing channel 3 and exiting from both the upper air outlet 21 and the lower air outlet 22.

[0069] Fresh air module 4 has an air inlet end and an air outlet end. The air inlet end is used to connect to the outdoor environment, and the air outlet end is connected to the housing channel 3. The fresh air module 4 can introduce outdoor fresh air into the housing channel 3 when the air duct component 2 delivers air through different air delivery paths.

[0070] The housing 1 is also provided with an air inlet that connects to the housing channel 3. The air inlet can be controlled to open or close so that when outdoor fresh air is introduced into the housing channel 3, the external airflow of the air conditioner can be selectively introduced through the air inlet to mix with the fresh air, so that the air conditioner has different fresh air outlet modes.

[0071] The cabinet air conditioner provided in this embodiment of the invention enables the air duct component to form different air supply paths by setting a flow control mechanism in the air duct component. At the same time, a fresh air module is set and connected to the air conditioner's body casing channel. In this way, when the fan in the air duct component runs and introduces fresh air, the fresh air can enter the air duct component 2 through the body casing channel 3 and switch with the air supply path of the air duct component to achieve the effect of supplying fresh air to different positions. Meanwhile, the air inlet on the air conditioner casing 1 can be controlled to open or close. When the air inlet is closed, the fresh air module can act as the air inlet of the air conditioner to provide air volume to the air conditioner, thereby realizing an independent fresh air supply mode. When the air inlet is opened, the fresh air module can also provide air volume to the entire air conditioner, thereby realizing a large air volume mixed fresh air supply mode.

[0072] In some implementations, such as Figure 7 and Figure 8 As shown, the air inlet includes an upper air inlet 13 located at the top of the housing 1 and / or a lower air inlet 14 located at the bottom of the housing 1.

[0073] Preferably, air inlets are provided at both the top and bottom of the casing 1, which can increase the air intake of the entire air conditioner.

[0074] In some embodiments, the opening and closing of the upper air inlet 13 and the lower air inlet 14 are controlled by baffles, i.e. Figures 11-14 As shown, an upper baffle plate 1i is rotatably installed at the upper air inlet 13 to control the opening and closing of the upper air inlet 13, and a lower baffle plate 1h is rotatably installed at the lower air inlet 14 to control the opening and closing of the lower air inlet 14.

[0075] Of course, in some alternative implementations, the opening and closing of the upper air inlet 13 and the lower air inlet 14 can also be achieved by other mechanisms, such as setting on / off valves or other on / off components at the positions of the upper air inlet 13 and the lower air inlet 14. In this embodiment, the specific on / off structure of the upper air inlet 13 and the lower air inlet 14 is not limited.

[0076] In some implementations, such as Figure 7and Figure 8 As shown, the cabinet air conditioner has a front side facing the user when installed, and a rear side opposite the front side;

[0077] The downvent 12 is located at the bottom front of the air conditioner, and the fresh air module 4 is located at the bottom rear of the air conditioner.

[0078] By placing the downvent 12 at the bottom front of the air conditioner, the hot air can fully contact the bottom surface and rise when the air conditioner is in heating mode, thereby improving the heating effect of the air conditioner. By placing the fresh air module 4 at the bottom rear of the air conditioner, it is convenient to connect the air inlet pipe of the fresh air module to the outside, and it is convenient to install the pipeline of the fresh air module 4.

[0079] In some implementations, such as Figures 3-6 As shown, the air duct component 2 has an upper air supply duct 2a, an upper fan air duct 2b, an intermediate air duct 2c, a lower fan air duct 2d and a lower air supply duct 2e arranged vertically and connected to each other. The upper part of the upper air supply duct 2a is connected to the upper air outlet 11, and the lower part of the lower air supply duct 2e is connected to the lower air outlet 12.

[0080] The flow path control mechanism includes an upper flow path control mechanism and a lower flow path control mechanism installed on the air duct component;

[0081] The upper flow path control mechanism can connect the upper fan duct 2b and the upper air supply duct 2a while blocking the connection between the upper fan duct 2b and the middle air duct 2c. The upper flow path control mechanism can also connect the upper fan duct 2b and the middle air duct 2c while blocking the upper fan duct 2b and the upper air supply duct 2a.

[0082] The downstream flow control mechanism can connect the downstream fan duct 2d and the downstream air supply duct 2e while simultaneously blocking the connection between the downstream fan duct 2d and the intermediate air supply duct 2c. The downstream flow control mechanism can also connect the downstream fan duct 2d and the intermediate air supply duct 2c while simultaneously blocking the downstream fan duct 2d and the downstream air supply duct 2e.

[0083] By setting up upper and lower flow path control mechanisms, the air duct components can achieve air delivery effects with different air delivery paths. Specifically:

[0084] When the air conditioner needs to achieve simultaneous airflow from both the top and bottom, the upper fan duct 2b can be connected to the upper air supply duct 2a while simultaneously blocking the connection between the upper fan duct 2b and the middle air duct 2c by controlling the upper flow path control mechanism. Simultaneously, the lower fan duct 2d can be connected to the lower air supply duct 2e while simultaneously blocking the connection between the lower fan duct and the middle air duct by controlling the lower flow path control mechanism. Then, the upper fan in the upper fan duct and the lower fan in the lower fan duct are started simultaneously. Figures 9-12As shown, the ductwork component can simultaneously deliver air from both the top and bottom. When fresh air needs to be introduced, the fresh air module 4 can be opened to bring in outside fresh air. It's worth noting that when the ductwork component simultaneously delivers air from both the top and bottom to introduce outside fresh air, different modes of fresh air delivery can be achieved by controlling the opening and closing of the air inlet on the air conditioner casing. Specifically, as... Figure 9 As shown, when an independent fresh air mode is needed, the air inlet on the air conditioner casing can be closed, at which point only the fresh air module 4 will receive air. More specifically, as... Figure 12 As shown, when a mixed fresh air mode is required, the air inlet on the air conditioner casing can be opened. At this time, not only fresh air module 4 can take in air, but also the air inlet on the air conditioner casing can take in air.

[0085] When the air conditioner needs to achieve a single-upper-ventilation effect, the upper fan duct 2b can be connected to the upper air supply duct 2a while simultaneously blocking the connection between the upper fan duct 2b and the intermediate duct 2c by controlling the upper flow path control mechanism. Then, the upper fan in the upper fan duct can be started alone, achieving a single-upper-ventilation effect. Simultaneously, when fresh air needs to be introduced, the fresh air module 4 can be opened to bring outside fresh air into the room. It is worth noting that when the duct component introduces outside fresh air in a single-upper-ventilation mode, different modes of fresh air supply can be achieved by controlling the opening and closing of the air inlet on the air conditioner casing. Specifically, when an independent fresh air mode is needed, the air inlet on the air conditioner casing can be closed, at which point only the fresh air module 4 receives air. More specifically, when a mixed fresh air mode is needed, the air inlet on the air conditioner casing can be opened, at which point not only the fresh air module 4 receives air, but also the air inlet on the air conditioner casing receives air.

[0086] When the air conditioner needs to achieve a single-downward air supply effect, the lower fan duct 2d can be connected to the lower air supply duct 2e while simultaneously blocking the connection between the lower fan duct 2d and the intermediate duct 2c by controlling the lower airflow control mechanism. Then, the lower fan in the lower fan duct can be started alone, achieving a single-downward air supply effect. Simultaneously, when fresh air needs to be introduced, the fresh air module 4 can be opened to bring outside fresh air into the room. It is worth noting that when the duct component introduces outside fresh air in a single-downward air supply mode, different modes of fresh air supply can be achieved by controlling the opening and closing of the air inlet on the air conditioner casing. Specifically, when an independent fresh air mode is needed, the air inlet on the air conditioner casing can be closed, at which point only the fresh air module 4 receives air. More specifically, when a mixed fresh air mode is needed, the air inlet on the air conditioner casing can be opened, at which point not only the fresh air module 4 receives air, but also the air inlet on the air conditioner casing receives air.

[0087] As can be seen, when the air conditioner in this embodiment delivers fresh air, the fresh air introduced from the outside can flow to different positions in the room by switching the flow path of the air duct component, thereby achieving a variable fresh air delivery effect. At the same time, when delivering fresh air, an independent fresh air mode or a mixed fresh air mode can be selected. Since the exhaust side of the fresh air module in this embodiment is directly connected to the air intake side of the air duct component's housing channel, when the air conditioner is running in mixed fresh air mode, the outside airflow introduced from the fresh air module 4 and the indoor airflow introduced from the air inlet of the air conditioner can be mixed in the housing channel and then uniformly discharged into the room. Thus, in this mode, the air volume of the air conditioner can be increased, and the air delivery effect can be improved.

[0088] In some implementations, such as Figures 3-6 As shown, the upper flow path control mechanism can also connect the upper fan duct 2b and the upper air supply duct 2a to the middle air duct 2c at the same time as connecting the upper fan duct 2b and the upper air supply duct 2a. The upper flow path control mechanism can also block the connection between the upper air supply duct 2a and the middle air duct 2c at the same time as blocking the upper fan duct 2b and the upper air supply duct 2a.

[0089] The downstream flow control mechanism can also connect the downstream fan duct 2d and the downstream air supply duct 2e to the intermediate air supply duct 2c at the same time. The downstream flow control mechanism can also block the connection between the downstream air supply duct 2e and the intermediate air supply duct 2c while blocking the downstream fan duct 2d and the downstream air supply duct 2e.

[0090] The advantages of configuring the upper flow path control mechanism and the lower flow path control mechanism as described above in this embodiment are:

[0091] When the air conditioner needs to achieve a single-top air supply effect, the upper fan duct 2b and the upper air supply duct 2a can be connected by controlling the upper flow path control mechanism. At the same time, while blocking the upper fan duct 2b and the middle duct 2c, the upper air supply duct 2a and the middle duct are connected. Then, the upper fan in the upper fan duct and the lower fan in the lower fan duct are started simultaneously. In this way, the lower fan in the lower fan duct 2d can discharge the intake airflow through the middle duct 2c into the upper air supply duct 2a and finally discharge it from the top, thereby improving the air supply power of the air conditioner when it is in single-top air supply, and thus improving the air supply distance and air supply intensity of the air conditioner in single-top air supply.

[0092] Similarly, when the air conditioner needs to achieve a single downward air supply effect, the downward air supply duct 2e can be connected by controlling the downward flow path control mechanism. At the same time, while blocking the downward air supply duct 2d and the intermediate air supply duct 2c, the downward air supply duct 2e and the intermediate air supply duct 2c are connected. Then, the upper fan in the upper fan duct and the lower fan in the lower fan duct are started simultaneously. In this way, the upper fan in the upper fan duct 2b can discharge the intake airflow through the intermediate air supply duct 2c into the downward air supply duct 2e and finally discharge it from the bottom. This improves the air supply power of the air conditioner when it is supplying air only from the top, thereby increasing the air supply distance and air supply intensity of the air conditioner when it is supplying air only from the top.

[0093] In some implementations, such as Figures 3-6 As shown, the upper air vent 11 and the lower air vent 12 can be controlled to open or close; the upper air supply duct 2a has an upper return air vent 23 on its duct wall that connects the fuselage housing channel 3 and the upper air supply duct 2a, and the lower air supply duct 2e has a lower return air vent 24 on its duct wall that connects the fuselage housing channel 3 and the lower air supply duct 2e.

[0094] The upper flow path control mechanism can close the upper return air outlet 23 while connecting the upper air supply duct 2a and the upper fan duct 2b, and open the upper return air outlet 23 when blocking the connection between the upper air supply duct 2a and the upper fan duct 2b.

[0095] The downflow control mechanism can close the downflow return air inlet 24 while connecting the downflow air duct 2e and the downflow fan duct 2d, and open the downflow return air inlet 24 when blocking the connection between the downflow air duct 2e and the downflow fan duct 2d.

[0096] In this embodiment, by providing return air vents on the walls of both the upper air supply duct 2a and the lower air supply duct 2e, and further modifying the upper and lower flow path control mechanisms, the air volume supplied by the air conditioner when only the upper or lower air outlet is located can be further increased. Specifically:

[0097] like Figure 9 and Figure 12As shown, when the air conditioner needs to achieve a single upward air supply effect, the upper fan duct 2b and the upper supply duct 2a can be connected by controlling the upper flow path control mechanism. At the same time, while blocking the upper fan duct 2b and the middle duct 2c, the upper supply duct 2a and the middle duct 2c are connected, and the upper return air vent 23 is closed accordingly. Then, the lower fan duct 2d and the lower supply duct 2e are disconnected by controlling the lower flow path control mechanism. While blocking the lower supply duct 2e and the middle duct 2c, the lower return air vent 24 is opened. Then, the upper fan in the upper fan duct and the lower fan in the lower fan duct are started simultaneously. In this way, the lower fan in the lower fan duct 2d can draw air from the bottom of the air conditioner into the lower supply duct 2e when it is running. The air entering the lower supply duct 2e passes through the lower return air vent 24 and the body casing channel in sequence and is then drawn into the fan of the duct component, and finally discharged from the top of the air conditioner, thereby increasing the air supply volume of the air conditioner when it is in single upward air supply mode.

[0098] Similarly, such as Figure 10 and Figure 14 As shown, when the air conditioner needs to achieve a single downward air supply effect, the lower fan duct 2d and the lower supply duct 2e can be connected by controlling the lower flow path control mechanism. At the same time, while blocking the lower fan duct 2d and the middle duct 2c, the lower supply duct 2e and the middle duct 2c are connected, and the lower return air vent 24 is closed accordingly. Then, the upper fan duct 2b and the upper supply duct 2a are disconnected by controlling the upper flow path control mechanism. While blocking the upper supply duct 2a and the middle duct 2c, the upper return air vent 23 is opened. Then, the upper fan in the upper fan duct and the lower fan in the lower fan duct are started simultaneously. In this way, the upper fan in the upper fan duct 2b can draw air from the top of the air conditioner into the upper supply duct 2a when it is running. The air entering the upper supply duct 2a passes through the upper return air vent 23 and the body casing channel in sequence and is then drawn into the fan of the duct component and finally discharged from the bottom of the air conditioner, thereby increasing the air supply volume of the air conditioner when it is in single downward air supply mode.

[0099] In some implementations, such as Figures 2-5 As shown, the cabinet air conditioner also includes an upper fan 5 located in the upper fan duct 2b and a lower fan 6 located in the lower fan duct 2d.

[0100] The upper air supply duct 2a has an upper air supply duct A side close to the upper fan 5 and an upper air supply duct B side close to the upper air outlet 11. The upper air supply duct 2a includes a first upper air supply duct 2a1 and a second upper air supply duct 2a2 that are separated on the upper air supply duct A side and connected on the upper air supply duct B side.

[0101] The downflow duct 2e has a downflow duct A side close to the downflow fan 6 and a downflow duct B side close to the downflow outlet. The downflow duct 2e includes a first downflow duct 2e1 and a second downflow duct 2e2 that are separated on the downflow duct A side and connected on the downflow duct B side.

[0102] The upper flow path control mechanism includes an upper baffle mechanism 71 rotatably positioned at the connection point between the upper fan duct 2b and the first upper supply air duct 2a1, and an upper volute mechanism 72 capable of circumferentially sliding around a preset rotation axis of the upper fan 5. The upper baffle mechanism 71 has a first upper rotation position and a second upper rotation position when rotating, and the upper volute mechanism 72 has a first upper sliding position and a second upper sliding position when sliding. When the upper baffle mechanism 71 is in the first upper rotation position, the upper return air vent 23 is opened, simultaneously blocking the upper fan duct 2b and the first upper supply air duct 2a1. When the upper baffle mechanism 71 is in the second upper rotating position, the upper return air vent 23 is closed and the upper fan duct 2b and the first upper supply air duct 2a1 are connected. When the upper volute mechanism 72 is in the first upper sliding position, the upper fan duct 2b is connected to the middle air duct 2c while blocking the connection between the upper fan duct 2b and the second upper supply air duct 2a2. When the upper volute mechanism 72 is in the second upper sliding position, the upper fan duct 2b is connected to the second upper supply air duct 2a2 while blocking the connection between the upper fan duct 2b and the middle air duct 2c.

[0103] The downstream flow control mechanism includes a lower baffle mechanism 81 rotatably positioned at the connection point between the downstream fan duct 2d and the first downstream air supply duct 2e1, and a lower volute mechanism 82 capable of circumferentially sliding around a preset rotation axis of the downstream fan 6. The lower baffle mechanism 81 has a first downward rotation position and a second downward rotation position when rotating, and the lower volute mechanism 82 has a first downward sliding position and a second downward sliding position when sliding. When the lower baffle mechanism 81 is in the first downward rotation position, the downstream return air inlet 24 is opened, simultaneously blocking the downstream fan duct 2d and the first downstream air supply duct. When the lower baffle mechanism 81 is in the second lower rotation position, the lower return air vent 24 is closed while simultaneously connecting the lower fan duct 2d and the first lower supply air duct 2e1. When the lower volute mechanism 82 is in the first lower sliding position, the lower fan duct 2d is connected to the middle air duct 2c while simultaneously blocking the connection between the lower fan duct 2d and the second lower supply air duct 2e2. When the lower volute mechanism 82 is in the second sliding position, the lower fan duct 2d is connected to the second lower supply air duct 2e2 while simultaneously blocking the connection between the lower fan duct 2d and the middle air duct 2c.

[0104] In this embodiment, both the upper flow path control mechanism and the lower flow path control mechanism adopt a baffle plus volute motion mode, thereby realizing multiple air supply modes of the air conditioner.

[0105] It should be noted that the worm tongue motion mechanism provided in this embodiment adopts a mature mechanism, and the specific composition and operating principle of the worm tongue motion mechanism will not be described in detail in this embodiment.

[0106] In some implementations, such as Figure 7 and Figure 8As shown, the upper fan 5 and the lower fan 6 are centrifugal fans, and the rotation directions of the upper fan 5 and the lower fan 6 are opposite.

[0107] In some implementations, such as Figure 7 and Figure 8 As shown, the cabinet air conditioner also includes:

[0108] The heat exchange component 9 includes an upper heat exchange section 91 and a lower heat exchange section 92 disposed in the housing channel 3. The upper heat exchange section 91 is opposite to the axial air inlet of the upper fan 5, and the lower heat exchange section 92 is opposite to the axial air inlet of the lower fan 6.

[0109] By placing the heat exchange components in the casing channel 3 and placing them opposite the axial air inlet of the fan, the airflow entering the fan can be fully heat-exchanged, thus improving the heat exchange effect.

[0110] In some embodiments, the upper fan 5 and the lower fan 6 are double-suction centrifugal fans that can be axially inlet from both sides, wherein the heat exchange component 9, which is composed of the upper heat exchange section 91 and the lower heat exchange section 92, is configured as a V-shaped heat exchange component with the notch facing the air inlet of the centrifugal fan.

[0111] In this embodiment, by setting the heat exchange component 9 in a V-shape, the airflow flowing from top to bottom or from bottom to top inside the air conditioner can fully contact the heat exchanger, thereby improving the heat exchange effect of the airflow.

[0112] In some implementations, such as Figure 1 As shown, the aforementioned cabinet air conditioner can be composed of the following components, specifically including: front panel 1a, right side panel 1b, air outlet frame component 1c, lower channel 1d, left side panel 1e, top cover 1f, and chassis 1g. The front panel 1a, right side panel 1b, left side panel 1e, and right side panel 1b form the outer perimeter of the cabinet air conditioner. The top cover 1f is located on the top of the air conditioner, and the chassis 1g is located at the bottom of the air conditioner. The air outlet frame component 1c is located on the top of the air duct component 2, with its upper end connected to the upper air outlet 11 on the air conditioner casing and its lower end connected to the upper air duct opening 21 on the top of the air duct component 2. The lower channel 1d is located at the bottom of the air duct component, with its upper end connected to the lower air duct opening 22 at the bottom of the air duct component 2 and its lower end connected to the lower air outlet 12 at the bottom of the air conditioner casing.

[0113] It should be noted that the air outlet frame component 1c and the lower channel 1d can be either separate or integrally molded with the air duct component. That is, the air outlet frame component 1c and the lower channel 1d can be part of the air duct component.

[0114] It is worth noting that the upper return air vent 23 and lower return air vent 24 mentioned above can also be set on the air outlet frame component 1c or the lower channel 1d, respectively, and can achieve the same air outlet effect.

[0115] This invention proposes an air conditioner with fresh air supply and reversible return air. The fresh air module is placed at the lower rear of the air conditioner, and the air outlet of the fresh air module is located in the housing channel 3 inside the air conditioner. Wind deflectors are set at corresponding positions of the upper air inlet 13 and the lower air inlet 14 of the air conditioner housing. Opening and closing the wind deflectors causes the upper air inlet 13 and the lower air inlet 14 to open and close synchronously. The air blown out by the fresh air module 4 passes through the heat exchange component 9 and, depending on the air inlet and outlet modes of the air conditioner, achieves different fresh air outlet modes.

[0116] Specifically, the cabinet air conditioner in this embodiment of the invention may include, but is not limited to, the following operating modes.

[0117] Independent fresh air mode

[0118] When the user selects the fresh air mode, the upper wind deflector 1i and the lower wind deflector 1f are closed, as are the upper air inlet 13 and the lower air inlet 14.

[0119] Mode 1: When the user selects the single top air outlet mode, the upper baffle mechanism 71 closes the upper return air vent 23, the middle air duct 2c connects to the first upper supply air duct 2a1, the upper volute mechanism 72 connects the upper fan duct 2b to the second upper supply air duct 2a2, the lower baffle mechanism 81 opens the lower return air vent 24, the middle air duct 2c disconnects from the first lower supply air duct 2e1, the lower volute mechanism 82 connects the lower fan duct 2d to the middle air duct 2c, the lower air outlet 12 closes, the upper centrifugal fan system and the lower centrifugal fan system start simultaneously, the fresh air module 4 starts, outdoor air enters through the air inlet of the fresh air module 4, and is blown out through the fresh air outlet under the filtration effect of the fresh air module 4. The blown fresh air enters the casing channel 3, and after the fresh air in the casing channel 3 is heat-exchanged by the heat exchange component 9, part of the air enters the two centrifugal fan systems from the rear air inlet of the air duct component 2, and the other part of the air enters through the ventilation opening 25 on the air duct component 2. Figure 3 and Figure 4 As shown, the air enters the cavity formed by the sealing cover 26 and the duct casing, and enters the two centrifugal fan systems through the air inlet on the front side of the duct component. Part of the air, under the action of the upper centrifugal fan system, passes through the second upper air supply duct 2a2 and the air outlet frame component 1c, and is blown out from the upper air outlet 11. The other part of the air, under the action of the lower centrifugal fan system, passes through the middle air duct 2c, the first upper air supply duct 2a1, and the air outlet frame component 1c, and is blown out from the upper air outlet 11. The air from both centrifugal fan systems converges on the air outlet frame component 1c and is finally blown out from the upper air outlet 11, achieving single-top fresh air output and rapidly purifying the air quality in the upper part of the room. Figure 10 As shown.

[0120] Mode 2: When the user selects the single-downward air outlet mode, the upper baffle mechanism opens the upper return air vent 23, the middle air duct 2c is disconnected from the first upper supply air duct 2a1, the upper volute mechanism 72 connects the upper centrifugal fan system to the middle air duct 2c, the lower baffle mechanism closes the lower return air vent 24, the middle air duct 2c connects to the first downward supply air duct 2e1, the lower volute mechanism 82 connects the lower centrifugal fan system to the second downward supply air duct 2e2, the upper air vent 11 is closed, the upper and lower centrifugal fan systems are turned on simultaneously, the fresh air module 4 is turned on, outdoor air enters through the fresh air module 4 inlet, is filtered by the fresh air module 4 and blown out through the fresh air outlet, the blown fresh air enters the casing channel 3, and the fresh air in the casing channel 3 passes through the heat exchange components. 9. After heat exchange, a portion of the air enters the two centrifugal fan systems through the rear air inlet of the duct component, while the other portion enters the cavity formed by the sealing cover 26 and the volute through the vent 25 on the duct component, and then enters the two centrifugal fan systems through the front air inlet of the duct component. A portion of the air, under the action of the upper centrifugal fan system, passes through the middle air duct 2c, the first lower air supply duct 2e1, and the lower channel 1d, and is blown out from the lower air outlet 12. The other portion of the air, under the action of the lower centrifugal fan system, passes through the second lower air supply duct 2e2 and the lower channel 1d, and is blown out from the lower air outlet 12. The air from both centrifugal fan systems converges into the lower channel 1d and is finally blown out from the lower air outlet 12, achieving single-bottom fresh air output and rapidly purifying the air quality in the lower indoor area. Figure 11 As shown.

[0121] Mode 3: When the user selects the simultaneous upper and lower air outlet mode, the upper baffle mechanism 71 closes the upper return air vent 23, the lower baffle mechanism 81 closes the lower return air vent 24, the upper volute mechanism 72 connects the upper fan duct 2b to the second upper supply air duct 2a2, and the lower volute mechanism 82 connects the lower fan duct 2d to the second lower supply air duct 2e2. The upper and lower centrifugal fan systems are turned on simultaneously, and the fresh air module 4 is turned on. Outdoor air enters through the air inlet of the fresh air module 4, is filtered by the fresh air module 4, and is blown out through the air outlet of the fresh air module 4. The blown fresh air enters the casing channel 3, and the fresh air in the casing channel 3 passes through the heat exchange components. After heat exchange, part of the air enters the two centrifugal fan systems through the rear air inlet of the duct component 2, while the other part enters the cavity formed by the sealing cover 26 and the volute through the vent 25 on the duct component, and then enters the two centrifugal fan systems through the front air inlet of the duct component 2. Part of the air, under the action of the upper centrifugal fan system, passes through the second upper air supply duct 2a2 and the air outlet frame component 1c, and is blown out from the upper air outlet 11. The other part of the air, under the action of the lower centrifugal fan system, passes through the second lower air supply duct 2e2 and the lower channel 1d, and is blown out from the lower air outlet 12, achieving simultaneous fresh air supply from both the upper and lower sections, rapidly purifying the air quality in any location within the room. Figure 9 As shown.

[0123] When the user selects the mixed fresh air mode, the upper wind deflector 1i and the lower wind deflector 1f open, and the upper air inlet 13 and the lower air inlet 14 open.

At the air inlet, both the upper and lower centrifugal fan systems are activated simultaneously, and the fresh air module 4 is turned on. Outdoor air enters through the air inlet of the fresh air module 4, is filtered by the fresh air module 4, and is blown out through the air outlet of the fresh air module 4. The blown-out fresh air enters the casing channel 3. Part of the indoor air enters from the lower air inlet 12, passes through the lower channel 1d and the lower return air inlet 24, and enters the casing channel 3. The other part of the air enters the machine through the upper air inlet 13 and the lower air inlet 14 respectively. In the casing channel 3, all the air mixes within the casing channel 3 and then passes through the heat exchange component 9. Part of the air enters the two centrifugal fan systems from the rear air inlet of the air duct component 2, while the other part enters the cavity formed by the sealing cover 26 and the volute through the vent 25 on the air duct component. It then enters the two centrifugal fan systems through the front air inlet of the air duct component 2. Part of the air, under the action of the upper centrifugal fan system, passes through the second upper air duct 2a2 and the air outlet frame component 1c, and is blown out from the upper air outlet 11. The other part of the air, under the action of the lower centrifugal fan system, passes through the middle air duct 2c, the first upper air duct 2a1, and the air outlet frame component 1c, and is blown out from the upper air outlet 11. The air from both centrifugal fan systems converges at the air outlet frame component 1c and is finally blown out from the upper air outlet 11. This achieves both cooling and fresh air output from the upper air outlet 11, increasing the airflow of the air conditioner and allowing users to intuitively feel that the air is fresher during cooling. Figure 13 As shown.

[0125] Mode 2: When the air conditioner is in heating mode, the user selects the single-downward air outlet mode. The upper baffle mechanism 71 opens the upper return air vent 23, the middle air duct 2c is disconnected from the first upper supply air duct 2a1, the upper volute mechanism 72 connects the upper centrifugal fan system to the middle air duct 2c, the lower baffle mechanism 81 closes the lower return air vent 24, the middle air duct 2c is connected to the first downward supply air duct 2e1, the lower volute mechanism 82 connects the lower centrifugal fan system to the second downward supply air duct 2e2, and the upper air vent 11 is converted... With the air inlet 11 and both the upper and lower centrifugal fan systems activated simultaneously, the fresh air module 4 is turned on. Outdoor air enters through the air inlet of the fresh air module 4, is filtered by the fresh air module 4, and is blown out through the air outlet of the fresh air module 4. The blown-out fresh air enters the casing channel 3. Part of the indoor air enters from the upper air inlet 11, passes through the air outlet frame component 1c and the upper return air inlet 23, and enters the casing channel 3. The other part of the air enters from the upper air inlet 13 and the lower air inlet 14 respectively. The air enters the casing channel 3. After mixing within the channel 3 and passing through the heat exchange component 9, a portion of the air enters the two centrifugal fan systems from the rear air inlet of the duct component 2. The other portion enters the cavity formed by the sealing cover 26 and the volute through the vent 25 on the duct component 2, and then enters the two centrifugal fan systems through the front air inlet of the duct component 2.

The other portion of the air, under the action of the lower centrifugal fan system, passes through the second lower air supply duct 2e2 and the lower channel 1d, and is blown out from the lower air outlet 12. The air from both centrifugal fan systems converges into the lower channel 1d and is finally blown out from the lower air outlet 12. This achieves both heating and fresh air output from the lower air outlet 12, increasing the airflow of the air conditioner and allowing users to intuitively perceive cleaner air during heating. Figure 14 As shown.

[0126] Mode 3: When the air conditioner is in rapid cooling or rapid heating mode, the user selects the simultaneous upper and lower air outlet mode. The upper baffle mechanism 71 closes the upper return air vent 23, and the lower baffle mechanism 81 closes the lower return air vent 24. The upper volute mechanism 72 connects the upper centrifugal fan system to the second upper air supply duct 2a2, and the lower volute mechanism 82 connects the lower centrifugal fan system to the second lower air supply duct 2e2. The upper and lower centrifugal fan systems are turned on simultaneously, and the fresh air module 4 is turned on. Outdoor air enters through the air inlet of the fresh air module 4, is filtered by the fresh air module 4, and is blown out through the air outlet of the fresh air module 4. The blown fresh air enters the casing channel 3. Indoor air enters the casing channel 3 from the upper air inlet 13 and the lower air inlet 14 respectively. All the air enters the casing channel 3. After mixing in channel 3 and heat exchanged by heat exchange component 9, part of the air enters the two centrifugal fan systems through the rear air inlet of duct component 2, while the other part enters the cavity formed by the sealing cover 26 and the volute through the vent 25 on duct component 2, and then enters the two centrifugal fan systems through the front air inlet of duct component 2. Part of the air, under the action of the upper centrifugal fan system, passes through the second upper air supply duct 2a2 and the air outlet frame component 1c, and is blown out from the upper air outlet 11. The other part of the air, under the action of the lower centrifugal fan system, passes through the second lower air supply duct 2e2 and the lower channel 1d, and is blown out from the lower air outlet 12, achieving simultaneous airflow from both the upper and lower sections. This increases the airflow of the air conditioner by introducing fresh air and promotes rapid indoor air circulation, accelerating indoor air purification. Figure 12 As shown.
