Description

Technical Field

[0001] The invention relates to the technical field of air conditioners, and in particular provides a suspended air conditioner. Background Art

[0002] Ceiling air conditioners are a type of air conditioner that is suspended from the indoor ceiling and is widely used in indoor buildings such as shopping malls and office buildings.

[0003] In the prior art, ceiling air conditioners are usually embedded, that is, the main body of the air conditioner is embedded in the ceiling, with only the bottom panel exposed. The return air inlet and the supply air outlet are both arranged on the bottom panel, which causes a 180-degree reversal of air flow from the return air inlet to the supply air outlet, resulting in greater wind resistance.

[0004] Accordingly, the art needs to provide a new technical solution to solve the above problems. Summary of the invention

[0005] In order to at least partially overcome the above-mentioned defects, the present invention is proposed. Specifically, the present invention provides a suspended air conditioner that can at least partially solve the technical problem of large wind resistance of ceiling air conditioners.

[0006] The first aspect of the present invention provides a suspended air conditioner, comprising: a shell having a return air outlet and an air supply outlet; a fan assembly, which is arranged in the shell; wherein the return air direction corresponding to the return air outlet includes a vertical direction, and the supply air direction corresponding to the supply air outlet includes a direction having an angle with the vertical direction.

[0007] It can be seen that there is an angle between the return air direction and the supply air direction of the suspended air conditioner in the embodiment of the present invention. In this way, the reversing angle of the air from the return air outlet to the supply air outlet will be less than 180 degrees, which makes the suspended air conditioner in the embodiment of the present invention have smaller wind resistance than the suspended air conditioner provided in the prior art. At the same time, the supply air direction includes a direction having an angle with the vertical direction, which helps to increase the air supply range of the suspended air conditioner.

[0008] In a technical solution of the above-mentioned suspended air conditioner, the air supply direction corresponding to the air supply port includes a horizontal direction.

[0009] Through such a structure, a possible arrangement method of the air outlet is provided, and this arrangement method can prevent cold air from blowing directly on the user during cooling by the suspended air conditioner.

[0010] In a technical solution of the above-mentioned suspended air conditioner, at least a portion of the return air outlet is located on the top wall of the shell.

[0011] Through such a structure, a possible setting method of the return air outlet is provided.

[0012] In a technical solution of the above-mentioned suspended air conditioner, the fan assembly includes a diagonal flow fan, and when projected along the air outlet direction of the diagonal flow fan, the projection surface of the air supply outlet completely covers the projection surface of the air outlet of the diagonal flow fan.

[0013] With such a configuration, the wind resistance of the suspended air conditioner can be further reduced.

[0014] In a technical solution of the above-mentioned suspended air conditioner, the suspended air conditioner includes: a baffle, which is movably connected to the position of the shell corresponding to the return air outlet; and / or a dust collection structure, which is arranged in the position of the shell corresponding to the return air outlet.

[0015] With such a configuration, it is possible to reduce dust from entering the housing and / or adhering to related components in the housing.

[0016] In a technical solution of the above-mentioned suspended air conditioner, the baffle includes a plurality of sub-parts, and the plurality of sub-parts are movable relative to each other.

[0017] Such a configuration provides a possible structural form of the baffle.

[0018] In a technical solution of the above-mentioned suspended air conditioner, the suspended air conditioner includes: an air guide assembly, which is arranged at a position of the shell corresponding to the air supply port, and the air guide assembly includes a first group of air guide plates and a second group of air guide plates, wherein one of the first group of air guide plates and the second group of air guide plates can be switched between an open state and a closed state independently of the other of the first group of air guide plates and the second group of air guide plates.

[0019] Through such a structure, the air supply distance of the suspended air conditioner can be adjusted to meet the different usage requirements of users.

[0020] In a technical solution of the above-mentioned suspended air conditioner, the first group of air guide plates corresponds to a first area of ​​the air supply port, the second group of air guide plates corresponds to a second area of ​​the air supply port, and the area of ​​the first area is smaller than that of the second area.

[0021] With such a configuration, the adjustable range of the air blowing distance can be expanded.

[0022] In a technical solution of the above-mentioned suspended air conditioner, the first area is below the second area.

[0023] In a technical solution of the above-mentioned suspended air conditioner, the first group of air guide plates is fixedly connected to the shell and thus always remains in an open state.

[0024] With such a configuration, a driving mechanism may be provided only for the second group of air guide plates, without providing a driving mechanism for the first group of air guide plates, which reduces the cost and facilitates control during actual use. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0034] The embodiment of the present invention first provides a suspended air conditioner, referring to Figure 1-Figure 4 The suspended air conditioner includes a housing 1 and a fan assembly 2, wherein the housing 1 has a return air port 11 and an air supply port 12. The fan assembly 2 is disposed in the housing 1, and is used to guide air to enter the housing 1 from the return air port 11, flow to the air supply port 12 in the housing 1, and flow out of the housing 1 from the air supply port 12. The return air direction corresponding to the return air port 11 includes a vertical direction, and the air supply direction corresponding to the air supply port 12 includes a direction having an angle with the vertical direction.

[0035] The return air direction and the supply air direction of the suspended air conditioner in the embodiment of the present invention have an angle, so that the reversing angle of the air from the return air outlet 11 to the supply air outlet 12 will be less than 180 degrees, which makes the suspended air conditioner in the embodiment of the present invention have smaller wind resistance than the suspended air conditioner provided in the prior art. At the same time, the supply air direction includes a direction having an angle with the vertical direction, which helps to increase the air supply range of the suspended air conditioner.

[0036] The return air direction corresponding to the return air port 11 here refers to the flow direction of the air when it enters the housing 1 through the return air port 11 during the actual operation of the suspended air conditioner. The vertical direction here can be vertically upward or vertically downward. Similarly, the supply air direction corresponding to the supply air port 12 refers to the flow direction of the air when it flows out of the housing 1 through the supply air port 12.

[0037] The direction having an angle with the vertical direction may include but is not limited to the horizontal direction, and the horizontal direction here may refer to any direction in the horizontal plane. In a possible implementation, there may be multiple air supply directions corresponding to the air supply port 12, in which case, at least part of the multiple air supply directions should have an angle with the vertical direction.

[0038] It is understandable that after the shell 1 is installed on the ceiling, the air outlet 12 needs to be exposed outside the ceiling to realize its function. In order to make the air supply direction of the air outlet 12 include a direction having an angle with the vertical direction, the wall of the shell 1 corresponding to the air outlet 12 needs to have an angle with the vertical direction. Therefore, a part of the shell 1 corresponding to the air outlet 12 is bound to protrude from the ceiling. In the case where there is a suspended ceiling on the ceiling, since the suspended ceiling has occupied a part of the floor height, the height of the shell 1 protruding from the ceiling should not be too high, otherwise it will bring a sense of oppression to the user. In this case, the air supply direction can be set to a direction that is at an acute angle to the vertical direction according to the actual situation to avoid the above problem to a certain extent. In the case where there is no suspended ceiling on the ceiling, this problem will not exist.

[0039] In one possible implementation, refer to Figure 1 and Figure 2 , at least a part of the structure of the housing 1 may be a columnar structure, for example Figure 1 The cylindrical structure shown in Figure 2The prismatic structure shown in FIG. The return air outlet 11 can be located at one or both ends of the housing 1 in the axial direction, and the air outlet 12 can be arranged along the circumference of the columnar structure. When the housing 1 is mounted on the ceiling, the air outlet 12 faces multiple directions in the horizontal plane, that is, the air supply direction corresponding to the air outlet 12 includes multiple directions in the horizontal plane. This arrangement enables the suspended air conditioner to supply air in all directions, with a larger air supply range, and can supply air in a direction roughly parallel to the ceiling to prevent cold air from blowing directly on people.

[0040] Obviously, the setting mode of the shell 1 is not limited to this, such as the shell 1 can also be set to a truncated cone structure, a prism structure, a pyramid structure or even an irregular structure. The setting mode of the return air outlet 11 is also not limited to this, such as the return air outlet 11 can also be set on the top wall of the shell 1, or the return air outlet 11 can be set on both the top wall and the bottom wall of the shell 1. The setting mode of the air supply outlet 12 is also not limited to this, for example, the air supply outlet 12 can have only one direction. Those skilled in the art can set it according to actual use requirements.

[0041] Further, refer to Figure 3 In the above embodiment, the fan assembly 2 may include a centrifugal fan 21. The dotted line in the figure shows the approximate flow direction of the air under the guidance of the centrifugal fan 21. Since the air supply port 12 in this embodiment is arranged circumferentially around the columnar structure, the centrifugal fan 21 can be a centrifugal fan with annular air outlet.

[0042] Further, in the above embodiment, referring to Figure 3 The air conditioner may include a heat exchange component 3. In this embodiment, at least a portion of the heat exchange component 3 may be an annular structure, and the annular structure may be located between the air outlet and the air supply port 12 of the centrifugal fan 21. Obviously, the arrangement of the heat exchange component 3 is not limited to this, such as the heat exchange component 3 may also be arranged between the return air port 11 and the centrifugal fan 21, but compared with this arrangement, the arrangement of this embodiment can reduce the overall thickness of the suspended air conditioner, thereby improving its aesthetics.

[0043] In the embodiments described above, the return air port 11 is located on the bottom wall of the housing 1 . However, in some possible embodiments, at least a portion of the return air port 11 may also be located on the top wall of the housing 1 .

[0044] In the case where the return air port 11 is located on the top wall of the housing 1, refer to Figure 4, the fan assembly 1 may include a diagonal flow fan 22. A diagonal flow fan is a type of fan between an axial flow fan and a centrifugal fan, and its impeller can make the air do both centrifugal motion and axial motion, so its air outlet direction is diagonally downward, for this reason, in this embodiment, the air supply port 12 is arranged at a position diagonally below the diagonal flow fan 22, specifically, when projected along the air outlet direction of the diagonal flow fan 22, the projection surface of the air supply port 12 completely covers the projection surface of the air outlet of the diagonal flow fan 22, so that all the air blown out by the diagonal flow fan 22 can flow directly to the air supply port 12 without changing direction.

[0045] Such a setting can further reduce the wind resistance of the suspended air conditioner. Experimental data show that, under the condition that other conditions are roughly the same, the wind resistance of the traditional suspended air conditioner with both the return air vent and the air supply vent facing vertically downward is about 100 Pa, the wind resistance of the suspended air conditioner described in some embodiments above, where the air inlet 11 is located on the bottom wall, the air supply direction is horizontal, and the centrifugal fan 21 is used, is about 60 Pa, while the wind resistance of the suspended air conditioner in this embodiment is about 40 Pa.

[0046] Obviously, those skilled in the art can understand that when the return air outlet 11 is located on the top wall of the shell 1, the centrifugal fan 21 can also be selected. When the return air outlet 11 is located on the bottom wall of the shell 1, the diagonal flow fan 22 can also be selected. In a possible embodiment, the return air outlet 11 can include multiple return air outlets, a part of the return air outlet 11 can be located on the top wall of the shell 1, and another part of the return air outlet 11 can be located on the bottom wall of the shell 1, that is, the suspended air conditioner can take in air from both sides. In this case, the fan assembly 2 can include two centrifugal fans / diagonal flow fans, or the fan assembly 2 can include one centrifugal fan and one diagonal flow fan.

[0047] Furthermore, when at least a portion of the return air inlet 11 is located on the top wall of the shell 1, dust can more easily enter the shell 1 through the return air inlet 11. Therefore, in these cases, the suspended air conditioner may also include a baffle 4 and / or a dust collection structure 5.

[0048] The baffle 4 is movably arranged at a position of the housing 1 corresponding to the return air outlet 11, so that it can switch between the state of shielding the return air outlet 11 and the state of exposing the return air outlet 11. Therefore, when the suspended air conditioner is not needed, the return air outlet 11 can be shielded by the baffle 4 to prevent dust from entering the housing 1, and when the suspended air conditioner is needed, the baffle 4 can be removed to expose the return air outlet 11. As an example, the baffle 4 may include a plurality of sub-parts, and the plurality of sub-parts can move relative to each other so that the baffle 4 can switch between the state of shielding the return air outlet 11 and the state of exposing the return air outlet 12. The advantage of this embodiment is that it can shorten the movable space required for the baffle 4 to switch between the state of shielding the return air outlet 11 and the state of exposing the return air outlet 12.

[0049] The dust collection structure 5 can be any suitable container, which can be set in the housing 1 at a position corresponding to the return air port 11, so that dust will be collected in the dust collection structure 5 after entering the housing 1 through the return air port 11, so as to avoid dust accumulation in positions such as the fan assembly 2 and the heat exchange assembly 3, which may increase the wind resistance of the suspended air conditioner and deteriorate the cooling / heating effect. In a possible embodiment, the dust collection structure 5 may also have the ability to actively absorb dust, for example, it may include an electrostatic adsorption structure, and those skilled in the art may set it according to actual needs.

[0050] Further, in the case where at least a portion of the return air outlet 11 is located on the top wall of the housing 1, the space on the bottom wall of the housing 1 is released. Figure 1 and Figure 2 The bottom wall of the housing 1 may be provided with a functional component 6, which may include one or more of a lighting component, a sound component, and a display component. The lighting component may include devices such as LED lights, the sound component may be devices such as audio, and the display component may be devices such as electronic display screens. These functional components 6 usually need to be hung on the ceiling or other indoor walls for use. Integrating these functional components 6 on the suspended air conditioner can improve the cleanliness of the indoor ceiling and bring a better experience to users.

[0051] In one possible implementation, refer to Figure 1 and Figure 2 The suspended air conditioner also includes an air guide assembly 7 , which is arranged at a position of the shell 1 corresponding to the air outlet 12 , and the air guide assembly 7 may include a first group of air guide plates 71 and a second group of air guide plates 72 .

[0052] exist Figure 1 and Figure 2In the embodiment shown in FIG. 1 , the first group of air guide plates 71 includes air guide plates arranged along the circumference of the housing 1, but those skilled in the art will readily appreciate that the arrangement of the first group of air guide plates 71 is not limited thereto, such as the first group of air guide plates 71 may include only one air guide plate. The structure of the air guide plate may be adapted to the structure of the housing 1. For example, in the case of using Figure 1 In the case of the cylindrical housing shown in the figure, the air guide plate can be a curved plate structure, while in the case of Figure 2 In the case of the prismatic shell shown, the air guide plate may be a flat plate structure. In the case where the first set of air guide plates 71 includes a plurality of air guide plates, the plurality of air guide plates may also be arranged along other directions, and the plurality of air guide plates may have the same structure or may have different structures, and those skilled in the art may make specific arrangements according to actual use requirements. Similarly, the second set of air guide plates 72 is also the same.

[0053] The first group of air guide plates 71 and / or the second group of air guide plates 72 may have an open state and a closed state. The open state refers to a state in which the windward surface of one or more air guide plates in the group forms a certain angle with the surface where the air outlet 12 is located. In the open state, air can flow out of the housing 1 in the area corresponding to the air outlet 12 and the group of air guide plates. The closed state refers to a state in which the windward surfaces of all air guide plates in the group cover the surface where the air outlet 12 is located. In the closed state, air cannot flow out of the housing 1 in the area corresponding to the air outlet 12 and the group of air guide plates.

[0054] The first set of air guide plates 71 and / or the second set of air guide plates 72 can be switched between an open state and a closed state by being movably connected to the housing 1. The specific mode of the movably connected state can be a rotating connection, a sliding connection, or a combination of the two, etc., and the air guide plates can be driven to move relative to the housing 1 by means of a suitable driving mechanism, so as to switch between an open state and a closed state. The specific setting mode can refer to the setting mode of the air guide plates in the prior art of the present invention, and will not be described in detail here.

[0055] Further, in this embodiment, one of the first group of air guide plates 71 and the second group of air guide plates 72 can be switched between an open state and a closed state independently of the other of the first group of air guide plates 71 and the second group of air guide plates 72. This function can be achieved by providing independent driving mechanisms for the first group of air guide plates 71 and the second group of air guide plates 72, or can also be achieved in other ways to be described below.

[0056] It can be seen that, through such a configuration, the air guide assembly can have at least two use states. In the first use state, Figure 5 , the first set of air guide plates 71 and the second set of air guide plates 72 are both in an open state. In the second use state, refer to Figure 6, one of the first group of air guide plates 71 and the second group of air guide plates 72 can be in an open state, and the other can be in a closed state. When the fan speed of the air conditioner 2 remains unchanged, after the air guide assembly switches from the first use state to the second use state, the area of ​​the air outlet 12 that allows air to pass through will decrease, so that the air flow rate is accelerated, thereby increasing the air supply distance of the air conditioner 2. In other words, the air guide assembly of this embodiment can change the air supply distance of the air conditioner, so that the air conditioner 2 can supply air in a more diverse air supply mode to meet the different usage needs of users.

[0057] The advantages of the above-mentioned air guide assembly in specific use will be described below by way of example through two usage scenarios.

[0058] The first usage scenario is that the air conditioner 2 is in heating mode, where the air conditioner 2 blows out hot air. It is understandable that when there is both cold air and hot air in the room, the hot air will move upward under the action of buoyancy. If the air conditioner 2 can only send the hot air to a position at a certain height from the ground, it may take a long time for the hot air to diffuse to a position close to the ground, and the user may feel hot head and cold feet, which is a poor experience. In this scenario, the first set of air guide plates 71 can be opened and the second set of air guide plates 72 can be closed, thereby increasing the air supply distance of the air conditioner so as to send the hot air to a position closer to the ground and improve the user experience.

[0059] The second usage scenario is that the air conditioner 2 is in cooling mode, and the air conditioner 2 blows out cold air. In this usage scenario, both the first set of air guide plates 71 and the second set of air guide plates 72 can be opened, thereby ensuring that the entire indoor environment is cooled relatively quickly and preventing cold air from blowing directly onto the user's body, thereby improving the user experience.

[0060] In a possible embodiment, the first group of air guide plates 71 and / or the second group of air guide plates 72 may have multiple opening states. In different opening states, the angles formed by the windward surfaces of the air guide plates in the group and the surfaces where the air outlets 12 are located may be different, thereby guiding the air to flow along different angles.

[0061] For example, refer to Figure 6 and Figure 7 The second set of air guide plates 72 in the two figures are in different opening states. Figure 6 In the open state shown, the windward surface of the second set of wind guide plates 72 is approximately in a horizontal plane, so that the air can be guided to flow in an approximately horizontal direction. Figure 7 In the open state shown, the windward surface of the second set of wind guide plates 72 has an angle with the vertical direction, so that the air can be guided to flow in a direction having an angle with the vertical direction.

[0062] In a possible embodiment, the air outlet 12 includes a first area and a second area, a first group of air guide plates 71 are arranged at positions of the shell 1 corresponding to the first area, and a second group of air guide plates 72 are arranged at positions of the shell 1 corresponding to the second area, and the area of ​​the first area may be smaller than the area of ​​the second area.

[0063] The advantage of this arrangement is that the adjustable range of the air supply distance can be expanded, thereby better meeting the user's usage needs. Specifically, when both the first set of air guide plates 71 and the second set of air guide plates 72 are open, the air supply distance is at a minimum value. When the first set of air guide plates 71 is closed and the second set of air guide plates 72 is open, the air supply distance is at an intermediate value. When the first set of air guide plates 71 is open and the second set of air guide plates 72 is closed, the air supply distance is at a maximum value.

[0064] In a possible implementation, the first area is below the second area. The advantage of this arrangement is that, when the first air guide plate 71 is opened and the second air guide plate 72 is closed, that is, when the air supply distance is at the maximum value, the wind will be blown out from the lower half of the air outlet 12, that is, from a position closer to the ground, which will further ensure that the blown wind reaches the vicinity of the ground, thereby achieving a better heating effect.

[0065] Further, in the above situation, the first group of air guide plates 71 can be fixedly connected to the shell 1 and thus maintained in an open state, while the second group of air guide plates 72 can be movably connected to the shell 1 and switch between an open state and a closed state by movement relative to the shell 1.

[0066] The advantage of this setting method is that it is only necessary to set up a driving structure for the second group of air guide plates 72, thereby reducing costs. In actual use, it is only necessary to control the activities of the second group of air guide plates 72 without controlling the first group of air guide plates 71, thereby simplifying the control logic.

[0067] It is understandable that the fixed connection between the first set of air guide plates 71 and the housing 1 means that the flow direction of the gas flowing under the guidance of the first set of air guide plates 71 is not adjustable. In this embodiment, since the area of ​​the first region is smaller than the area of ​​the second region, when both the first set of air guide plates 71 and the second set of air guide plates 72 are in an open state, most of the air will flow out of the housing 1 from the position corresponding to the second region, especially when the angle between the windward surface of the second set of air guide plates 72 and the surface where the air supply port 12 is located is greater than the angle between the windward surface of the first set of air guide plates 71 and the air supply port 12 (in this case, the wind resistance at the second region will be smaller than the wind resistance at the first region, so that more air will flow through the second region). Therefore, only adjusting the angle between the windward surface of the second set of air guide plates 72 and the air supply port 12 can obtain a better air supply angle adjustment effect.

[0068] In a possible implementation, the suspended air conditioner may further include a controller, which may be used to: obtain an operation mode switching instruction; and control the first group of air deflectors and / or the second group of air deflectors according to the operation mode switching instruction. The controller is specifically used in the step of "controlling the first group of air deflectors and / or the second group of air deflectors according to the operation mode switching instruction" to: if the operation mode switching instruction indicates switching to the heating mode, then one of the first group of air deflectors and the second group of air deflectors is opened, and the other of the first group of air deflectors and the second group of air deflectors is closed.

[0069] As described above, this control method can increase the air supply distance of the air conditioner in the heating mode so as to deliver the hot air to a position closer to the ground, thereby improving the user experience. Further, in some embodiments, the first set of air guide plates 71 may be kept in an open state, in which case, only the second set of air guide plates need to be closed.

[0070] In a possible implementation, in the step of "controlling the first group of air guide plates and / or the second group of air guide plates according to the operating mode switching instruction", the controller opens both the first group of air guide plates and the second group of air guide plates if the operating mode switching instruction indicates switching to the cooling mode.

[0071] In a possible implementation, the cooling mode may include a conventional cooling mode, and after the step of "opening both the first set of air guide plates and the second set of air guide plates", the controller is further configured to: if the operation mode switching instruction indicates switching to the conventional cooling mode, at least move the second set of air guide plates to a position where air can be guided to flow in a substantially horizontal direction. In this embodiment, in the conventional cooling mode, air is guided to flow in a substantially horizontal direction, thereby preventing cold air from blowing directly onto the user and achieving a better cooling effect.

[0072] In a possible embodiment, the cooling mode may also include a rapid cooling mode, and after the step of "opening both the first group of air guide plates and the second group of air guide plates", the controller is also used to: if the operating mode switching instruction indicates switching to the rapid cooling mode, then at least the second group of air guide plates are moved to a position where the air can be guided to flow in a direction that is acute angled to the direction of gravity.

[0073] It can be understood that although under normal circumstances users do not want to be blown directly by cold wind, in some special situations, such as when the user has just come indoors from the hot outdoors, the user may want the cold wind to blow directly on his body so that he can quickly feel the coolness. For this reason, a rapid cooling mode is provided in the present embodiment. In the rapid cooling mode, the air is guided to flow in a direction forming an acute angle with the direction of gravity, so that the user can quickly feel the coolness.

[0074] As an example, in the normal cooling mode, the second set of air guide plates 72 can be moved to the position shown in FIG. 6 so that the windward surface thereof is approximately in a horizontal position, thereby guiding the air to flow in an approximately horizontal direction. Figure 7 The position shown directs the air to flow in a direction that is at an acute angle to the direction of gravity.

[0075] As described above, the first set of air guide plates 71 can be fixedly connected to the housing 1. In this case, only the second set of air guide plates 72 can be moved in the above manner. In the case where the first set of air guide plates 71 can be moved relative to the housing 1, the first set of air guide plates 71 and the second set of air guide plates 72 can be moved in the above manner together, or only the second set of air guide plates 72 can be moved in the above manner.

[0076] In a possible implementation, in the rapid cooling mode, the air supply angle may also be determined according to a control instruction from the user, that is, the user is allowed to select the air supply angle in the rapid cooling mode by himself, thereby providing the user with a better user experience.

[0077] An embodiment of the present invention further provides a control method for a suspended air conditioner, the method comprising the following steps: obtaining an operation mode switching instruction; controlling a first group of air deflectors and / or a second group of air deflectors according to the operation mode switching instruction. The step of "controlling the first group of air deflectors and / or the second group of air deflectors according to the operation mode switching instruction" specifically comprises: if the operation mode switching instruction indicates switching to the heating mode, one of the first group of air deflectors and the second group of air deflectors is opened and the other is closed.

[0078] In a possible implementation, the step of "controlling the first group of air guide plates and / or the second group of air guide plates according to the operation mode switching instruction" specifically includes: if the operation mode switching instruction indicates switching to the cooling mode, both the first group of air guide plates and the second group of air guide plates are opened.

[0079] In one possible embodiment, the cooling mode may include a conventional cooling mode. After the step of "opening both the first group of air guides and the second group of air guides", the method may include: if the operating mode switching instruction indicates switching to the conventional cooling mode, then at least the second group of air guides is moved to a position capable of guiding air to flow in a substantially horizontal direction.
