When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices consistent with some aspects of the present invention as detailed in the appended claims.

[0076] At present, the fresh air device in the existing cabinet air conditioner cannot introduce outdoor fresh air into the room after shutdown. An embodiment of the present invention provides a cabinet air conditioner. By providing two air outlets for the fresh air module, wherein the first air outlet communicates with the internal air duct of the air conditioner, and the second air outlet communicates with the indoor environment, and when one of the two air outlets is opened, the other can be controlled to close. In this way, when the fresh air module in the air conditioner fails and cannot be started, the first air outlet communicating with the internal air duct of the air conditioner can be opened, and the second air outlet communicating with the indoor environment can be closed. Thus, when the fresh air module is shut down or fails to start to provide fresh air for the room, the negative pressure in the internal cavity of the whole machine can suck the outdoor fresh air into the casing through the first air outlet, and discharge it into the room through the upper air outlet and / or the lower air outlet on the casing, achieving the fresh air effect.

[0077] The following will Figure 1 - be Figure 17 elaborate on the technical solutions of this embodiment in detail. Without conflict, the following embodiments and examples can be combined with each other.

[0078] Embodiment

[0079] As Figures 1 - 6 shown, this embodiment provides a cabinet air conditioner, including:

[0080] A casing 2, with an upper air outlet 21 at the top of the casing 2, a lower air outlet 22 at the bottom of the casing 2, and an air supply channel between the upper air outlet 21 and the lower air outlet 22 inside the casing 2. A heat exchange component 3 is provided in the air supply channel. The air conditioner has a single lower air outlet mode with upper air inlet and lower air outlet, and a single upper air outlet mode with lower air inlet and upper air outlet;

[0081] A fresh air module 4, which is provided with an air inlet 41, an air outlet 42, and a fresh air control mechanism for controlling the air outlet 42;

[0082] The air inlet 41 is used to communicate with the outdoor environment. The air outlet 42 includes a first air outlet 421 communicating with the air supply channel and a second air outlet 422 communicating with the indoor environment;

[0083] The fresh air control structure can control the opening of the first air outlet 421 while controlling the closing of the second air outlet 422, and control the opening of the second air outlet 422 while controlling the closing of the first air outlet 421.

[0084] In the embodiment of the present utility model, by providing two air outlets for the fresh air module 4 {the first air outlet 421 and the second air outlet 422}, where the first air outlet 421 communicates with the air supply channel inside the air conditioner, and the second air outlet 422 communicates with the indoor environment. When one of the two air outlets is opened, the other can be controlled to close. In this way, when the fresh air module 4 in the air conditioner fails and cannot be turned on, the first air outlet 421 communicating with the air supply channel inside the air conditioner can be opened, and the other second air outlet 422 communicating with the indoor environment can be closed. In this way, when the fresh air module 4 stops operating or fails to turn on to provide fresh air for the room, the fresh air outside can be sucked into the housing 2 through the first air outlet 421 by the negative pressure of the air supply channel inside the whole machine, and discharged into the room through the upper air outlet 21 / or the lower air outlet 22 on the housing 2, achieving the fresh air effect.

[0085] That is, the cabinet air conditioner in the embodiment of the present utility model can achieve the fresh air effect without turning on the fresh air module 4. When the user wants to turn off the fresh air function of the air conditioner, when setting the fresh air function to be turned off, the fresh air control mechanism can be used to control the first air outlet 421 to close and control the second air outlet 422 to open. At this time, the air outlets of the fresh air module {the first air outlet 421 and the second air outlet 422} are not connected to the air supply channel inside the housing 2, and fresh air cannot be sucked into the housing 2 without the power provided by the fresh air fan blade.

[0086] It should be noted that in the embodiment of the present utility model, the upper air outlet 21 on the housing 2 does not require it to be completely at the top of the housing. Similarly, the lower air outlet 22 on the housing 2 does not require it to be completely at the bottom of the housing. In some embodiments not shown, the upper air outlet 21 only needs to be arranged close to the top of the housing 2, and similarly, the lower air outlet 22 only needs to be arranged close to the bottom of the housing 2.

[0087] It should also be noted that for the existing mass-produced cabinet machines, their air intake method is rear-side air intake, and the air intake cross-sectional area is large enough, so there is no need to set the air outlet of the fresh air module 4 on the air intake side of the whole machine to provide the air intake volume.

[0088] Furthermore, as Figure 1 、 Figure 2 and Figure 4 shown, the housing 2 includes a front side with a front panel, a rear side opposite to the front side, and an outer peripheral side between the front side and the rear side;

[0089] wherein the second air outlet 422 of the fresh air module 4 opens on the outer peripheral side of the housing 2.

[0090] In the embodiment of the present utility model, by arranging the second air outlet 422 of the fresh air module on the outer peripheral side of the casing 2, it is possible to avoid affecting the overall appearance of the unit due to the opening at the front of the casing 2.

[0091] Furthermore, the fresh air module 4 is arranged closer to the lower air outlet 22 of the casing 2 relative to the upper air inlet 21 and the lower air outlet 22 of the casing 2. In this embodiment, by arranging the fresh air module 4 closer to the lower air outlet 22 of the casing 2, it is convenient to install the fresh air module 4.

[0092] In any of the above embodiments, as Figure 6 shown, the fresh air module further includes:

[0093] A fresh air volute 4a, on which the above-mentioned fresh air inlet 41, the first air outlet 421 and the second air outlet 422 are formed;

[0094] A fresh air fan 4b, which is arranged inside the fresh air volute 4a and is used for sucking the outdoor ambient air flow into the fresh air volute 4a and discharging it through the first air outlet 421 and / or the second air outlet 422; wherein the fresh air fan 4b includes a blade driving motor and a centrifugal blade;

[0095] A fresh air filter screen 4c, which is arranged at the position of the fresh air inlet 41 and is used for filtering the outdoor ambient air flow sucked into the fresh air volute 3a;

[0096] The fresh air control mechanism includes a baffle 4d rotatably arranged between the first air outlet 421 and the second air outlet 422. The baffle 4d is used for controlling the opening and closing of the first air outlet 421 and the opening and closing of the second air outlet 422. When the baffle is driven to rotate, it has a first rotation position and a second rotation position;

[0097] Wherein when the baffle 4d is in the first rotation position, the baffle 4d can open the first air outlet 421 while closing the second air outlet 422. When the baffle 4d is in the second rotation position, the baffle 4d can close the first air outlet 421 while opening the second air outlet 422.

[0098] That is, in the embodiment of the present utility model, by controlling the rotation of the baffle 4d, the communication state between the first air outlet 421 and the second air outlet 421 can be controlled.

[0099] In any of the above embodiments, as Figure 1 、 Figure 2 and Figure 4 shown, the cabinet air conditioner further includes a fresh air module auxiliary air outlet 25 arranged on the outer peripheral side of the casing 2. One end of the fresh air module auxiliary air outlet 25 communicates with the external environment of the casing 2, and the other end communicates with the air supply channel inside the casing 2;

[0100] The outer peripheral side of the cabinet 2 includes a left side and a right side of the outer periphery of the cabinet that are oppositely arranged between the front side and the rear side of the cabinet. One of the fresh air module auxiliary air outlets 25 and the second air outlet 422 is provided on the left side of the outer periphery of the cabinet, and the other is provided on the right side of the outer periphery of the cabinet;

[0101] Among them, the shape of the fresh air module auxiliary air outlet 25 is adapted to the shape of the second air outlet 422, and the fresh air module auxiliary air outlet 25 and the second air outlet 422 are opposite in the left-right direction of the cabinet 2. Preferably, grilles are provided at both the fresh air module auxiliary air outlet 25 and the second air outlet 422.

[0102] In the embodiment of the present invention, by providing the fresh air module auxiliary air outlet 25 on the cabinet 2, on the one hand, the air intake volume of the cabinet can be increased, and on the other hand, by setting the fresh air module auxiliary air outlet 25 opposite to the second air outlet 422 of the fresh air module 4, the consistency of the overall appearance of the air conditioner can be ensured.

[0103] As can be seen from the above, the cabinet-type air conditioner in the embodiment of the present invention is a reversible air supply air conditioner, and its air intake method is different from the back air intake method of the existing air conditioner. Its air intake is from the top and the bottom, and the rear panel and the front panel cooperate to form a closed space in the front-rear direction of the whole machine. The air flow direction is from the vertical direction of the whole machine into the position of the heat exchange component, and then blown out by the centrifugal fan blade of the internal air duct component 100 of the cabinet 2.

[0104] The air conditioner includes a heat exchanger component, a front panel component, a rear panel component, an air duct component 100, an upper air outlet component, a lower air outlet component and a fresh air module.

[0105] The fresh air module of the air conditioner includes a fresh air filter screen 4c, a centrifugal fan blade, a fan blade drive motor, a fresh air pipe, a fresh air filter screen mounting rack, a fresh air volute 3a, a first air outlet 421, a second air outlet 422 and a baffle 4d. The fresh air module 4 can provide the air intake volume for the operation of the whole machine. The specific implementation method is as follows:

[0106] When the fresh air mode is turned on during the operation of the air conditioner, the fresh air module baffle is default to the open state {as Figure 4 and Figure 5 shown), at this time the first air outlet 421 is controlled to be closed, and the second air outlet 422 is controlled to be opened. At this time, the fresh air introduced by the fresh air module 4 from the outside through the air inlet 41 is drawn into the room by the centrifugal fan blade. At this time, the fresh air has not been heat-exchanged by the heat exchange component in the cabinet, which is the same as the existing technical solution.

[0107] When the air conditioner is set to the fast cooling or fast heating mode, the air conditioner needs a larger air intake volume in the super strong wind gear. At this time, the fresh air module baffle rotates to the closed state {as Figure 2 and Figure 3As shown in the figure, at this time, the first air outlet 421 of the fresh air module 4 is controlled to open, and the second air outlet 422 is controlled to close. At this time, the fresh air module 4 will draw the fresh air from the outside introduced through the air inlet 41 into the air supply duct in the casing 2 through the centrifugal fan blades, and after being heat-exchanged by the heat exchange component 3 in the air supply duct, it is blown out from the upper air outlet and / or the lower air outlet on the casing 2. In this way, the fresh air not only achieves the heat exchange effect, but also increases the air intake of the whole machine.

[0108] In addition, when the fresh air module 4 stops running or fails to start, the baffle 4d of the fresh air module 4 can be rotated to a closed state {as Figure 3 shown}, at this time, the first air outlet 421 is open and the second air outlet 422 is closed. Through the negative pressure formed in the air supply duct during the operation of the whole machine, the fresh air from the outside is inhaled. This function can achieve the fresh air effect without turning on the fresh air module 4. If the user wants to turn off the fresh air function of the air conditioner, when the fresh air function is set to be turned off, the baffle 4d rotates to the default open position. At this time, the first air outlet 421 of the fresh air module 4 is controlled to close, and the second air outlet 422 is controlled to open. The first air outlet 421 of the fresh air module 4 is not connected to the air supply duct in the casing 2, and the fresh air cannot be drawn into the casing 2 without the power provided by the fresh air fan blades.

[0109] In any of the above embodiments, as Figures 7 - 17 shown, the cabinet air conditioner further includes an air duct structure:

[0110] The air duct structure is arranged in the air supply passage and forms a body housing passage with the casing 2. The heat exchange component 3 is arranged in the body housing passage, and the body housing passage is communicated with the first air outlet 421 of the fresh air module 4;

[0111] The air duct structure includes an air duct component 100, and the air duct component 100 includes:

[0112] An air duct housing 10, an air blower installation cavity is formed inside the air duct housing 10 and an air blower air outlet passage communicated with the air blower installation cavity. The air duct housing 10 has opposite A side and B side in its thickness direction. The air duct housing 10 is also provided with a ventilation passage 12 penetrating through the A side and the B side in its thickness direction. The ventilation passage 12 includes a ventilation passage opening A121 opening on the A side of the air duct housing and a ventilation passage opening B122 opening on the B side of the air duct housing;

[0113] The double-suction fan 20 is disposed in the fan installation cavity. The double-suction fan 20 forms a fan air inlet A201 and a fan air inlet B202 on both sides in its axial direction. The fan air inlet A201 opens to the A side of the air duct housing, and the fan air inlet B202 opens to the B side of the air duct housing. The double-suction fan 20 further includes a fan air outlet communicating with the fan air inlet A201 and the fan air inlet B202, and the fan air outlet communicates with the fan air outlet passage;

[0114] The seal 30 is covered on the B side of the air duct housing. An auxiliary air duct 40 of the air duct component is formed between the seal 30 and the B side of the air duct housing. The air inlet end of the auxiliary air duct 40 of the air duct component communicates with the ventilation passage 12, and the air outlet end communicates with the fan air inlet B202 of the double-suction fan 20;

[0115] Wherein, the A side of the air duct component 100 faces the heat exchange component 3 in the air conditioner, so that a part of the air flow after heat exchange by the heat exchange component 3 can directly enter the double-suction fan 20 through the fan air inlet A201 opening on the A side of the air duct component, and another part can enter the double-suction fan 20 through the ventilation passage 12 and the auxiliary air duct 40 of the air duct component from the fan air inlet B202 opening on the B side of the air duct component.

[0116] In the air duct structure proposed in the embodiment of the present utility model, by opening a ventilation passage 12 on the air duct component 100 where the double-suction fan 20 is installed, and arranging a seal 30 on the air duct component 100, an auxiliary air duct 40 of the air duct component can be formed between the seal 30 and the ventilation passage 12. The auxiliary air duct 40 of the air duct component can introduce the air flow on one side of the axial direction of the double-suction fan 20 to the other side of the axial direction of the double-suction fan 20, so that when the air duct component 100 is installed in the air conditioner, only a heat exchanger needs to be arranged on one side of the axial direction of the double-suction fan 20 to enable the air flow after heat exchange to enter the double-suction fan 20 from the air inlets on both sides of the axial direction of the double-suction fan, thus eliminating the need to arrange heat exchangers on both sides of the axial direction of the double-suction fan 20, thereby reducing the production cost of the air conditioner and the size of the air conditioner while reducing the production cost of the air conditioner.

[0117] Specifically, when the air duct structure is installed in the air conditioner, the A side of the air duct component 100 in the air duct structure is opposed to the heat exchange component in the air conditioner. When the air flow in the air conditioner passes through the heat exchange component for heat exchange, a part of the air flow after heat exchange directly enters the double-suction fan 20 through the fan air inlet A201 on the A side of the air duct component, and another part of the air flow after heat exchange can enter the double-suction fan 20 through the ventilation passage 12 and the auxiliary air duct 40 of the air duct component from the fan air inlet B202 opening on the B side of the air duct component.

[0118] Further, as Figures 9 - 10As shown, the air outlet channel of the fan includes an air outlet channel one 13 and an air outlet channel two 14 with opposite openings in the height direction of the air duct component 100;

[0119] The air outlets of the double-suction fan 20 include an air outlet one 203 and an air outlet two 204. The air outlet one 203 is communicated with the air outlet channel one 13, and the air outlet two 204 is communicated with the air outlet channel two 14;

[0120] The double-suction fan 20 further includes a volute tongue movement mechanism 205 that can circumferentially slide around a preset rotation axis of the double-suction fan 20. The volute tongue movement mechanism 205 has a first sliding position and a second sliding position during circumferential sliding;

[0121] Wherein the volute tongue movement mechanism is designed such that when the volute tongue movement mechanism 205 is in the first sliding position, it is used to open the air outlet one 203 and shut off the air outlet two 204, so that the air flow discharged through the double-suction fan 20 can be discharged from the air outlet channel one 13 communicated with the air outlet one 203. When the volute tongue movement mechanism 205 is in the second sliding position, it is used to close the air outlet one 203 and open the air outlet two 204, so that the air flow discharged through the double-suction fan 20 can be discharged from the air outlet channel two 14 communicated with the air outlet two 204.

[0122] That is, the double-suction fan 20 in the embodiment of the present invention can control the air outlet of the air duct component 100 in different directions by setting a rotatable volute tongue movement mechanism 205 and controlling the sliding position of the volute tongue movement mechanism 205.

[0123] It should be noted that the volute tongue movement mechanism 205 in this embodiment borrows a mature mechanism and will not be introduced in detail.

[0124] In any of the above embodiments, as Figure 9 shown, a bypass air duct 50 is further formed inside the air duct housing 10:

[0125] One end of the bypass air duct 50 is arranged on the same side as the air outlet end of the air outlet channel one 13, and the other end is communicated with the air outlet channel two 14;

[0126] An air return opening 501 is formed on the air duct wall of the bypass air duct 50. One end of the air return opening 501 is communicated with the fuselage housing channel, and the other end is communicated with the bypass air duct 50;

[0127] A moving mechanism 60 is provided at the position of the return air outlet 501, and the moving mechanism 60 has a first moving position and a second moving position when moving. When the moving mechanism is in the first moving position, the return air outlet 501 is closed while the bypass air duct 50 and the fan air outlet channel 2 14 are connected. When the moving mechanism 60 is in the second moving position, the return air outlet 501 is opened while the connection between the bypass air duct 50 and the fan air outlet channel 2 14 is cut off.

[0128] In the embodiment of the utility model, a bypass air duct 50 is provided, and one end of the bypass air duct 50 is provided on the same side as the fan outlet channel 13, and the other end is communicated with the fan outlet channel 2 14. Preferably, the end of the bypass air duct 50 and the fan outlet channel 13 provided on the same side is communicated with the same air outlet on the air conditioner, and a return air outlet 501 and a motion mechanism 60 are provided at the air duct wall position of the bypass air duct 50, and the position of the volute tongue motion mechanism 205 is adjusted. In this way, when one of the fan outlet channel 13 and the fan outlet channel 2 14 in the air duct component 100 is discharging air, the other can take in air, thereby realizing the reversible air supply effect of the air conditioner.

[0129] Specifically, when the air duct component 100 is installed in the air conditioner, taking the fan outlet channel 13 in the air duct component 100 as an example, the return air port 501 can be opened at this time, and the bypass air duct 50 is connected to the fan outlet channel 2. Since the return air port 501 is in an open state at this time, the bypass air duct 50 is also connected to the inside of the air conditioner at this time, and because the inside of the air conditioner is also connected to the axial air inlet of the double-suction fan 20, when the fan outlet channel 13 is discharging air, the fan outlet channel 2 14 can take in air, and the airflow entering from the fan outlet channel 2 14 enters the inside of the air conditioner through the return air port 501, and enters through the axial air inlet of the double-suction fan 20 after heat exchange through the heat exchange component, and is finally discharged through the fan outlet channel 13.

[0130] Similarly, when the fan outlet channel 2 14 in the air duct component 100 is discharging air, the return air port 501 is also opened. At this time, the bypass air duct 50 is not connected to the fan outlet channel 2 14. At this time, the airflow located on the side of the fan outlet channel 1 13 passes through the bypass air duct 50 and enters the interior of the air conditioner from the return air port 501. After heat exchange in the heat exchange component, it enters through the axial air inlet of the double-suction fan 20, and is finally discharged through the fan outlet channel 2 14.

[0131] That is, when the air duct component 100 provided in the embodiment of the utility model is installed in an air conditioner, the reversible air supply effect of the air conditioner can be achieved by controlling the motion mechanism 60 and the volute motion mechanism 205 in the air duct component 100.

[0132] In any of the above embodiments, if Figures 7 - 9As shown, the side air duct 50 and the first blower outlet air duct 13 are located on both sides of the ventilation air duct 12 in the width direction of the air duct component 100.

[0133] In any of the above embodiments, as Figures 7 - 11 shown, the air duct structure includes two sets of air duct components 100, and the height direction of the air duct structure is the same as the height direction of the air duct component 100;

[0134] Among them, the two sets of air duct components 100 are in fluid communication through two blower outlet air ducts 14 in the two sets of air duct components, and two air duct component auxiliary air ducts 40 on the two sets of air duct components are connected to form an air duct structure auxiliary air duct;

[0135] Among them, the two air duct components 100 in the air duct structure include an upper air duct component located on the upper side and a lower air duct component located on the lower side in the height direction of the casing 2. The side air duct 50 and the first blower outlet air duct 13 in the upper air duct component are both communicated with the upper air outlet 21, and the side air duct 50 and the first blower outlet air duct 13 in the lower air duct component are both communicated with the lower air outlet 22;

[0136] Preferably, the two sets of air duct components 100 are symmetrically arranged in the height direction of the air duct structure;

[0137] Preferably, an intermediate air duct 70 is further formed between the two sets of symmetrically arranged air duct components 100. One end of the intermediate air duct 70 communicates with the external environment of the air duct structure, and the other end communicates with the air duct structure auxiliary air duct.

[0138] It should be noted that the intermediate air duct 70 has the same function as the ventilation air duct 12 in the above air duct component 100, that is, when the air duct structure is arranged in the air conditioner, a part of the air flow after heat exchange by the heat exchange component can directly enter the double-suction blower 20 through the blower air inlet A201 opening on the A side of the air duct component, and the other part can also enter the double-suction blower 20 through the ventilation air duct 12, the intermediate air duct 70 and the air duct component auxiliary air duct 40 and then through the blower air inlet B202 opening on the B side of the air duct component.

[0139] In any of the above embodiments, the seal 30 is a sealing cover covering the A side of the air duct housing. The material of the sealing cover can be made of pp material, so as to further reduce the noise of the air conditioner.

[0140] In summary, in the embodiment of the present invention, by arranging the above air duct structure in the casing 2, the reversible up and down air outlet effect of the cabinet air conditioner can be realized.

[0141] Specifically, the above cabinet air conditioner has a single upper air outlet cooling mode, a single lower air outlet heating mode, and an upper and lower simultaneous air outlet cooling or heating mode;

[0142] When the cabinet air conditioner operates in the upper air outlet cooling mode, the movement mechanism 60 in the upper air duct component is controlled to move to the first movement position to close the air return opening 501 of the upper air duct component while conducting the bypass air duct 50 and the second blower air outlet passage 14 in the upper air duct component. The scroll tongue movement mechanism 205 in the upper air duct component is controlled to slide to the first sliding position to conduct the first blower air outlet and the first blower air outlet passage 13 in the upper air duct component while shutting off the connection between the second blower air outlet and the second blower air outlet passage 14 in the upper air duct component. The movement mechanism 60 in the lower air duct component is controlled to move to the first movement position to open the air return opening 501 of the lower air duct component while shutting off the connection between the bypass air duct 50 and the second blower air outlet passage 14 in the lower air duct component. The scroll tongue movement mechanism 205 in the lower air duct component is controlled to slide to the second sliding position to shut off the first blower air outlet and the first blower air outlet passage 13 in the lower air duct component while conducting the second blower air outlet and the second blower air outlet passage 14 in the lower air duct component. At this time, when the double-suction blowers 20 in the upper and lower air duct components in the air duct structure operate synchronously, the lower air outlet 22 of the air conditioner is converted into an air inlet, and indoor air enters from the lower air outlet 22, passes through the air return opening 501 in the lower air duct component and enters the body housing passage. The air in the body housing passage is heated by the heat exchange component 3. Part of the heated air flow enters the two double-suction blowers 20 from the A side of the two air duct components 100, and the other part of the heated air flow enters the air duct component auxiliary air duct 40 formed by the seal 30 and the air duct component 100 through the ventilation passage 12 and the intermediate passage 70, and enters the two double-suction blowers 20 through the air inlet of the double-suction blowers 20 on the B side of the two air duct components 100. Part of the heated air flow is blown out through the upper first blower air outlet passage 13 under the action of the upper double-suction blower 20, and the other part of the heated air flow, under the action of the lower double-suction blower 20, successively passes through the lower second blower air outlet passage 14, the upper second blower air outlet passage 14 and the bypass air duct 50 and is blown out from the upper air outlet 21. The air blown by the upper and lower double-suction blowers 20 will converge into the upper passage 2e and be finally blown out from the upper air outlet 21, as Figure 12 and Figure 13 shown.

[0143] When the cabinet air conditioner operates in the single-bottom-air-outlet heating mode, the movement mechanism 60 in the upper air duct component is controlled to move to the second movement position to turn off the connection between the bypass air duct 50 and the fan air outlet channel two 14 in the upper air duct component while opening the air return port 501 of the upper air duct component. The volute tongue movement mechanism 205 in the upper air duct component is controlled to slide to the second sliding position to turn on the connection between the fan air outlet two and the fan air outlet channel two 14 in the upper air duct component while turning off the fan air outlet one and the fan air outlet channel one 13 in the upper air duct component. The movement mechanism 60 in the lower air duct component is controlled to move to the first movement position to turn on the connection between the bypass air duct 50 and the fan air outlet channel two 14 in the lower air duct component while closing the air return port 501 of the lower air duct component. The volute tongue movement mechanism 205 in the lower air duct component is controlled to slide to the first sliding position to turn off the connection between the fan air outlet two and the fan air outlet channel two 14 in the lower air duct component while turning on the connection between the fan air outlet one and the fan air outlet channel one 13 in the lower air duct component. At this time, the upper air outlet 21 on the air conditioner is converted into an air inlet, and the double-suction fans 20 located above and the double-suction fans 20 located below are turned on simultaneously. The indoor air enters from the upper air outlet 21, passes through the air return port 501 in the upper air duct component and enters the body housing channel. The air in the body housing channel is heated by the heat exchange component 3. Part of the heated air flow enters the two double-suction fans 20 from the A side of the two air duct components 100, and the other part of the heated air flow enters the air duct component auxiliary air duct 40 formed by the seal 30 and the air duct component 100 through the ventilation channel 13 and the middle channel 70, and enters the two double-suction fans 20 through the air inlet of the double-suction fans 20 on the B side of the two air duct components 100. Part of the heated air flow is blown out from the lower air outlet 22 after passing through the upper and lower connected fan air outlet channels two 14 under the action of the upper double-suction fan 20, and the other part of the heated air flow is blown out from the lower air outlet 22 after passing through the lower fan air outlet channel one 13 under the action of the lower double-suction fan 20. The air affected by the upper and lower double-suction fans 20 will converge into the lower channel 2f and finally be blown out from the upper air outlet 21 as shown in Figure 14 and Figure 15 shown

[0144] When the cabinet air conditioner operates in the mode of simultaneous upward and downward air supply for cooling or heating, the movement mechanism 60 in the upper air duct component is controlled to move to the first movement position, the air return opening 501 in the upper air duct component is closed, and the volute tongue movement mechanism 205 in the upper air duct component is controlled to slide to the first sliding position, so as to turn on the connection between the first air outlet of the blower in the upper air duct component and the first air outlet channel 13 while turning off the connection between the second air outlet of the blower in the upper air duct component and the second air outlet channel 14. The movement mechanism 60 in the lower air duct component is controlled to move to the first movement position, the air return opening 501 in the lower air duct component is closed, and the volute tongue movement mechanism 205 in the lower air duct component is controlled to slide to the first sliding position, so as to turn on the connection between the first air outlet of the blower in the lower air duct component and the first air outlet channel 13 while turning off the connection between the second air outlet of the blower in the lower air duct component and the second air outlet channel 14. At this time, the two double-suction blowers 20 above and below are turned on simultaneously. Indoor air enters the body shell channel from the upper air outlet 21 and the lower air outlet 22 respectively. After the air in the body shell channel exchanges heat through the heat exchange component 3, a part of the heat-exchanged air flow enters the two double-suction blowers 20 from the A side of the two air duct components 100, and another part of the heat-exchanged air flow enters the auxiliary air duct 40 of the air duct component formed by the seal 30 and the air duct component 100 through the ventilation channel 13 and the middle channel 70, and enters the two double-suction blowers 20 through the air inlet of the two double-suction blowers 20 on the B side of the two air duct components 100. A part of the heat-exchanged air flow is blown out from the upper air outlet 21 of the air conditioner after passing through the first air outlet channel 13 above and the upper channel 2e under the action of the upper double-suction blower 20, and another part of the heat-exchanged air flow is blown out from the lower air outlet 22 of the air conditioner after passing through the first air outlet channel 13 below and the lower channel 2f under the action of the lower double-suction blower 20, thus realizing the simultaneous upward and downward air supply of the air conditioner, as Figure 16 and Figure 17 shown

[0145] It should be noted that the positions of the air supply outlet and the air return outlet of traditional air conditioners are relatively unchanged. However, the indoor air temperature is stratified in the height direction. The hot air with low density gathers at the high position due to its low density, and the cold air with high density gathers at the low position due to its high density. As a result, the air conditioner with fixed air supply and return positions cannot take into account various working conditions, and there is an uneven phenomenon of temperature stratification in the height direction {thermal stratification phenomenon} in a certain working condition, and both energy conservation and comfort cannot reach the optimal level

[0146] Taking the floor-standing air conditioner with upward air supply and downward or rearward air return as an example, the air supply outlet is located at a relatively high position above the air conditioner. When cooling in summer and supplying cold air, the jet flow can quickly reach above the human activity area. Then, taking advantage of the fact that cold air flow has a large density and can naturally sink, it can achieve rapid cooling and a small blowing feeling, taking into account both the temperature drop and comfort effect. At the same time, since the air return outlet is located at the lower part of the air conditioner, the air return temperature is about 2°C lower than that in the middle and upper parts. Compared with the middle and upper part air return, the energy-saving effect is better. However, when heating in winter and supplying hot air, due to the principle that hot air rises, the heat jet flow cannot come down in the upper part of the room, resulting in the phenomenon of hot at the top and cold at the bottom. At this time, only the lower part returns air. Compared with the middle and upper part air return, more energy needs to be consumed to reach the same air supply temperature, and the energy-saving effect is poor. For air conditioners with fixed air supply and air return positions, the energy conservation and emission reduction and comfort experience in different refrigeration / heating working conditions cannot reach the best at the same time. Therefore, the traditional unidirectional air inlet and outlet circulation method cannot take into account both the energy conservation of refrigeration and heating and the comfort requirements. It is urgent to realize the transformation of the air inlet and outlet circulation method from unidirectional circulation to bidirectional reversible circulation. There are two existing implementation methods for reversible air supply air conditioners. One is to set a reversible axial flow fan and control the forward and reverse rotation of the motor of the axial flow fan to achieve reversible air supply. This method has high requirements for the manufacturing cost of the motor, and the axial flow fan has problems such as short air supply distance and small air pressure. The other is to set a mixed flow fan and achieve reversible air supply through the mixed flow fan blades. This method has a high fan speed, large noise, low work efficiency, and the energy-saving effect does not meet the requirements. Both of the above methods have problems such as large noise and small air volume, resulting in the energy conservation and comfort of the air conditioner not meeting the requirements and being unable to be productized. Moreover, the existing reversible air conditioners have a single air inlet and outlet passage, and the air passage cross-section is small and the process is long, resulting in a large air inlet resistance, and the air supply volume and noise of the air outlet cannot meet the requirements, and the air inlet and outlet methods are not diverse enough.

[0147] Due to the adoption of the above-mentioned air duct structure in the floor-standing air conditioner in the embodiment of the present invention, it can not only achieve the up and down reversible air supply effect of the air conditioner, but also reduce the production cost of the air conditioner while achieving the up and down reversible air supply effect {in the air conditioner in the embodiment of the present invention, only a heat exchanger needs to be set on one side of the air duct component}, and at the same time, it can also reduce the size of the air conditioner {since only a heat exchange component is set on one side of the air duct component in the air conditioner, the size of the air conditioner can be avoided from being large}, in addition, since the heat exchange component is only set on one side of the air duct component, the heat exchange component is easier to assemble during the whole machine manufacturing, so that the assembly efficiency during the production of the whole machine can also be improved.

[0148] It is worth noting that, as Figures 12 - 17 shown, the air conditioner further includes an upper auxiliary air outlet 23 located at the top of the housing 2 and a lower auxiliary air outlet 24 located at the bottom of the housing 2;

[0149] Both the upper auxiliary air outlet 23 and the lower auxiliary air outlet 24 communicate with the body housing passage.

[0150] In the embodiment of the present utility model, by providing an upper auxiliary air outlet 23 and a lower auxiliary air outlet 24 on the air conditioner housing 2 that communicate with the body housing channel, it is also possible to increase the air intake volume of the air conditioner during operation, thereby increasing the air output volume of the air conditioner.

[0151] In any of the above embodiments, as Figures 12 - 17 shown, the heat exchange component 3 includes a first heat exchanger 31 and a second heat exchanger 32. The first heat exchanger 31 and the second heat exchanger 32 are vertically butted to form a V-shaped heat exchange component with an opening facing the side of the air duct component B in the air duct structure;

[0152] Among them, the first heat exchanger 31 is opposite to the axial air inlet of the double-suction fan 20 in the upper air duct component, and the second heat exchanger 32 is opposite to the axial air inlet of the double-suction fan 20 in the lower air duct component.

[0153] Since the air conditioner in the embodiment of the present utility model is a cabinet-type air conditioner, and the air flow enters the air conditioner housing 2 from top to bottom or from bottom to top when the air conditioner intakes air, the heat exchange component 3 is arranged as two heat exchangers, and the V-shaped heat exchange component 3 with two heat exchangers has an opening facing the air inlet of the fan in the air duct structure, which can maximize the heat exchange effect on the air flow without increasing the size of the air conditioner.

[0154] In any of the above embodiments, as Figure 11 shown, the housing 2 includes:

[0155] a front panel 2a, an air intake component 2b, a left side panel 2c and a right side panel 2d. The front panel 2a, the air intake component 2b, the left side panel 2c and the right side panel 2d are enclosed together to form the housing 2;

[0156] The cabinet-type air conditioner further includes:
