[0036] Combination Figure 1 and Figure 2 The embodiment of the utility model provides an air guide device, which is arranged at the air outlet of the air conditioner 6, and the air guide device includes: a support member 1, a telescopic connecting rod member and a plurality of blades 3; the support member 1 is installed on the air conditioner 6 and is located at the side of the air outlet; the telescopic connecting rod member is installed on the support member 1 and can be telescopically moved along the side of the air outlet; the plurality of blades 3 are installed on the telescopic connecting rod member, and the telescopic connecting rod member is used to link the plurality of blades 3 to unfold and protect the air outlet when extending, and to link the plurality of blades 3 to gather and retract to the side of the air outlet when contracting.

[0037] The air guide device of this embodiment is preferably used in the air conditioner 6 of the computer room air conditioner. In order to realize that the air conditioner 6 can be flexible under some working conditions, for example, when the air outlet of the air conditioner 6 is working, if there is no interference nearby, it is hoped that there is no blade 3 in the air outlet to block the air flow (such as Figure 1 and Figure 4 If there is someone nearby, it is desirable that the air outlet be protected by blades 3 to prevent the person from accidentally touching the fan 61 in the air outlet (e.g. Figure 2 and Figure 5To this end, in this embodiment, a movable air guide device is provided at the air outlet of the air conditioner 6.

[0038] When it is necessary to prevent people from accidentally touching the fan 61 in the air outlet, the air guiding device of this embodiment drives the multiple blades 3 to extend to the maximum extent and protect the air outlet by the telescopic connecting rod; when efficient cooling is required, the telescopic connecting rod drives the multiple blades 3 to retract to the side of the air outlet to the maximum extent to avoid the blades 3 blocking the wind path of the air outlet, thereby ensuring the efficiency of cooling; that is, different modes can be switched according to different environmental conditions, which is flexible and changeable, and can not only avoid the air outlet to ensure the air outlet efficiency, but also act as a protective cover to protect the air outlet to prevent people from accidentally touching it.

[0039] In one embodiment, the air guiding device further includes at least one sensor 4 for monitoring whether a target object is close to the air guiding device; the sensor 4 is disposed on the support 1 or the air conditioner 6 .

[0040] In this embodiment, in order to facilitate the identification of the use environment of the air conditioner 6, a sensor 4 can be set on the support 1 or the air conditioner 6, and the sensor 4 can be an infrared sensor 4; when the sensor 4 does not detect someone approaching, the air guide device is in the first state to work; when the sensor 4 detects someone approaching, the air guide device switches to the second state to work.

[0041] In some embodiments, multiple sensors 4 (for example, 4) may be provided, and multiple sensors 4 may be provided on multiple sides (for example, 4 sides) of the air conditioner 6 to achieve multi-directional target recognition, so as to accurately identify the use environment of the air conditioner 6. It can be understood that multiple sensors 4 may also be provided on the four support portions 11 in the following example.

[0042] In one embodiment, the support member 1 includes: a support portion 11 and a guide rail 12; the support portion 11 is installed on the air conditioner 6 and is located on the side of the air outlet; the guide rail 12 is installed on the support portion 11 and is parallel to the side of the air outlet; the telescopic link member includes a driving member and a folding link 2 formed by a plurality of cross frames pivotally connected, the driving member is installed on the support portion 11, the folding link 2 is slidably connected to the guide rail 12, and the driving member is used to drive the folding link 2 to telescopically move on the guide rail 12 along the side of the air outlet; a plurality of blades 3 are installed side by side on the folding link 2 along the telescopic direction of the folding link 2.

[0043] In this embodiment, the support part 11 can be a column structure, and the support part 11 can be distributed at the side corners of the air outlet. The guide rail 12 can be a linear guide rail 12 with a slide groove, and the end of the guide rail 12 is fixed on the support part 11 and the guide rail 12 is parallel to the side of the air outlet; the driving member can be fixedly installed in the support part 11, one end of the folding link 2 is connected to the driving member, and the pivot position between the cross frames on the folding link 2 can be slidably connected to the slide groove of the guide rail 12 through a connecting shaft, and the folding link 2 can be driven by the driving member to perform telescopic movement on the guide rail 12; based on this, the blade 3 is installed on the folding link 2 and the blade 3 is perpendicular to the guide rail 12. Then, when the folding link 2 is driven to perform telescopic movement, the blade 3 can be linked to move in the air outlet, thereby realizing the retraction and expansion of the blade 3, that is, realizing the switching between the first state and the second state.

[0044] In this embodiment, the multiple cross frames of the folding link 2 can be folded or extended by pivoting, and the entire folding link 2 can be linked to be folded or extended by simply adjusting the cross angle of the cross frame on one end of the folding link 2; therefore, the driving member can be a motor, and the motor can rotate and drive the cross frame on one end of the folding link 2 to adjust the cross angle to achieve the folding or extension of the entire folding link 2; or the driving member can adopt a linear driving structure, and the connecting shaft at the pivot position between the driving cross frames can move in the slide groove of the guide rail 12, so that the entire folding link 2 can be folded or extended. The specific selection can be made according to the actual situation.

[0045] In one embodiment, a plurality of support members 1 are provided and distributed on opposite sides of the air outlet, a plurality of telescopic connecting rods are provided and installed one by one on corresponding support members 1; and both ends of the blade 3 are respectively connected to two opposite telescopic connecting rods.

[0046] In this embodiment, in order to ensure that the multiple blades 3 can avoid the air outlet as much as possible when they are retracted, the multiple blades 3 can be divided into two groups and distributed on the two sides of the air outlet. For this purpose, multiple support members 1 and multiple telescopic connecting rods need to be provided for cooperation. The guide rails 12 in the multiple support members 1 can be shared to reduce the complexity of the structure. For example, in some specific embodiments, four support parts 11 can be provided and distributed at the four corners of the air outlet, and two guide rails 12 can be provided and distributed on the opposite sides of the air outlet, the two ends of one guide rail 12 are respectively connected to two of the support parts 11, and the two ends of the other guide rail 12 are respectively connected to the other two support parts 11, and four telescopic connecting rods can be provided, and the four driving members of the telescopic connecting rod are provided on the four support parts 11 one by one, and the four folding links 2 of the telescopic connecting rod slide on the two guide rails 12.

[0047] Based on this specific embodiment, multiple blades 3 can be divided into two groups, with the two ends of one group of blades 3 respectively connected to two of the opposite folding links 2, and the two ends of the other group of blades 3 respectively connected to the other two opposite folding links 2; in this way, the two groups of blades 3 can be distributed on the two sides of the air outlet (i.e., the sides perpendicular to the guide rail 12) when they are contracted, and the two groups of blades 3 can cooperate to protect the air outlet when they are unfolded.

[0048] The following is a detailed introduction to further optimization schemes of this application.

[0049] In one embodiment, a rotating member 5 is provided at the pivot position of the folding link 2 , and at least one end of the blade 3 is connected to the corresponding rotating member 5 on the folding link 2 through the rotating member 5 ; the rotating member 5 is used to drive the blade 3 to rotate.

[0050] In this embodiment, a control power supply can be built into the support part 11, and the control power supply is connected to each rotating member 5 provided at the pivot position of the folding link 2. When the unit is shut down or encounters an accident and stops, the blades 3 will switch from the first state to the second state first, and then on the basis of the second state, the control power supply controls the rotating member 5 to work, and the rotating member 5 drives the blades 3 to rotate (the rotation angle is 90°), so that the multiple blades 3 completely close the air outlet (such as Figure 3 and Figure 6 In the third state, the unit can be shut down for a long time, and no wind blows out of the top air outlet, causing foreign matter and dust to fall into the unit and damage the unit.

[0051] For details, please refer to Figure 7 The rotating member 5 includes a fixed shaft 51, a micro motor 52 and a rotating shaft 53. The micro motor 52 is fixed at the pivot position of the folding link 2 through the fixed shaft 51. The micro motor 52 is electrically connected to the control power supply. The rotating shaft 53 is connected to the end of the blade 3. The micro motor 52 is controlled by the control power supply to work and drive the rotating shaft 53 to rotate to link the blade 3 to rotate.

[0052] In one embodiment, a cooling channel is provided inside the blade 3 along its length direction; the cooling channel is used to inject a coolant for cooling.

[0053] In this embodiment, the blade 3 can protect the air outlet in the second state and can also perform secondary cooling on the outlet air to improve indoor cooling efficiency. Specifically, a cooling channel can be opened in the blade 3 along its own length direction, and by injecting coolant for cooling into the cooling channel, the temperature of the blade 3 is reduced, thereby performing secondary cooling on the outlet air.

[0054] The utility model embodiment also provides an air conditioner, including a water receiving tray 62 (such as Figure 8), multiple cooling circulation pipes and air guide devices; the water receiving tray 62 is arranged inside the air conditioner 6 and is used to collect condensed water; the water receiving tray 62 and the cooling channels opened in the multiple blades 3 along their own length direction are circulated and connected one by one through multiple cooling circulation pipes.

[0055] In this embodiment, if the waste condensed water generated by the operation of the air conditioner 6 is directly discharged, it will cause a waste of air conditioning cooling capacity. Therefore, this embodiment makes effective use of the condensed water; the blades 3 in the above embodiment are designed with cooling channels. If the water receiving tray 62 of this embodiment is connected to the cooling channel of the blade 3, the recovered condensed water can be transported to the cooling channel for effective use, thereby achieving energy saving. Specifically, a plurality of cooling circulation pipes with the same number as the blades 3 can be added to the air conditioner 6, and the water receiving tray 62 and the cooling channels in the plurality of blades 3 are circulated and connected one by one through a plurality of cooling circulation pipes.

[0056] Combination Figure 8 The cooling circulation pipe fittings of this embodiment may include: a water pump 63, a first pipe 64 and a second pipe 65; the water pump 63 is arranged on the water receiving tray 62; one end of the first pipe 64 is connected to the water pump 63, and the other end of the first pipe 64 is connected to one end of the cooling channel corresponding to the blade 3; one end of the second pipe 65 is connected to the other end of the cooling channel corresponding to the blade 3, and the other end of the second pipe 65 is connected to the water receiving tray 62.

[0057] In this embodiment, a water level monitor can be set in the water receiving tray 62. When the water level monitor detects that the amount of condensed water reaches a set capacity, the air guide device switches to the second state, and then the water pump 63 extracts the condensed water in the water receiving tray 62 and transports it to one end of the cooling channel of the blade 3 through the first pipe 64. The condensed water is transported from one end of the cooling channel of the blade 3 to the other end to achieve heat exchange with the blade 3, and then flows back from the other end of the cooling channel to the second pipe 65, and then flows back to the water receiving tray 62 from the second pipe 65, thereby forming a circulating heat exchange. During this heat exchange process, the operating power of the compressor in the air conditioner 6 can be reduced, and the cooling capacity of the condensed water can be fully utilized to cool the outlet air, which has the advantages of reducing the energy consumption of the air conditioner 6 while avoiding waste of cooling capacity.

[0058] More specifically, when the heat exchange reaches a certain level, the built-in temperature sensor in the water receiving pan 62 detects that the water temperature reaches the set temperature, and then opens the water valve of the water receiving pan 62 to discharge the condensed water from the unit. At the same time, the air guide device switches back to the first state, and the compressor resumes normal operation, and waits for the water receiving pan 62 to collect the condensed water again.

[0059] In one embodiment, the air conditioner 6 also includes two limit bars 66, which are arranged on the air conditioner 6 and are respectively located on opposite sides of the air outlet; a limit opening is opened on the limit bar 66 along its own length direction, and the first pipe 64 and the second pipe 65 respectively enter the interior of the air conditioner 6 through the limit openings on the two limit bars 66.

[0060] In this embodiment, since the first pipe 64 and the second pipe 65 will move with the extension and retraction of the folding connecting rod 2, in order to ensure the stability of movement, a limit bar 66 is provided on the air conditioner 6. The limit bar 66 is installed on the air conditioner 6 and is located below the guide rail 12. The first pipe 64 and the second pipe 65 respectively enter the interior of the air conditioner 6 through the limit openings on the two limit bars 66 and then are connected to the water receiving tray 62. The first pipe 64 and the second pipe 65 are limited in movement through the limit openings, thereby ensuring stability during movement.

[0061] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
