Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an air outlet mechanism and a cabinet air conditioner using the same. Background Technology

[0002] Air conditioners have become standard equipment in modern home environments. Among them, cabinet air conditioners are widely used in large spaces such as living rooms due to their large cooling capacity and long air delivery distance. However, the current mainstream cabinet air conditioners on the market generally suffer from the technical bottleneck of having a single air outlet mode.

[0003] For example, Chinese patent "CN112178781B" discloses "a cabinet-type air conditioner". This air conditioner reduces the floor space occupied by the air conditioner, improves the cooling and heating effect, solves the problem of difficult cleaning of the rear air intake, and enhances the installation convenience of the air conditioner. However, the above-mentioned air conditioner adopts a design with a large air vent in the middle, and the airflow blows directly on the user when in use, which reduces the user experience.

[0004] For example, Chinese patent "CN113503588B" discloses "a cabinet-type air conditioner", which can increase the air outlet area and increase the sweeping angle of the airflow at the air outlet, thereby improving the indoor heat exchange effect. However, when the above air conditioner is in use, the overall air volume of the air conditioner is still relatively small, and it cannot meet the needs of users when they need direct fan blowing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an air outlet mechanism and a cabinet air conditioner using the same, which solves the problem that existing cabinet air conditioners cannot achieve top, middle, and bottom air outlets.

[0006] On one hand, according to an embodiment of the present invention, an air outlet mechanism includes:

[0007] The air outlet bracket is located in the middle of the air conditioner and has a channel running through both ends of it;

[0008] The soft wind bracket is located in the channel and includes two rotating surfaces and a sealing surface between the two rotating surfaces. The two rotating surfaces are respectively rotatably located on the inner side of the air outlet bracket.

[0009] The adjustment mechanism is located on the air outlet bracket and connected to one of the rotating surfaces. It is used to drive the sealing surface to rotate around the rotating surface as the axis, so as to seal or release the sealing of the passage opening.

[0010] Preferably, the adjustment mechanism is a first motor, which is located on the side of the air outlet bracket, and the output end of the first motor passes through the channel and is connected to one of the rotating surfaces.

[0011] Preferably, the air outlet mechanism also includes:

[0012] Mounting plate, located at the bottom of the sealing surface;

[0013] Several soft wind blades, each of which is equipped with a mounting shaft, and the mounting shafts are rotated at intervals on the mounting plate.

[0014] The drive assembly, located on the soft wind bracket and connected to each mounting shaft, is used to synchronously drive each mounting shaft to rotate.

[0015] Preferably, the driving component includes:

[0016] Several transmission gears are rotatably mounted on the mounting plate and correspond one-to-one with several mounting shafts, and the mounting shafts pass through the mounting plate and are connected to the transmission gears.

[0017] Several driven gears are rotatably mounted on the mounting plate and are respectively meshed between two adjacent transmission gears;

[0018] The driving component is connected to one of the transmission gears.

[0019] Preferably, the driving component includes:

[0020] A sector bevel gear, connected to one of the transmission gears;

[0021] The driving bevel gear is rotatably located inside the rotating surface, and the driving bevel gear meshes with the sector bevel gear;

[0022] The second motor is located on the outer side of the rotating surface, and the output end of the second motor is connected to the driving bevel gear.

[0023] Preferably, the mounting plate is provided with several clips, all of which are engaged with the inner side of the sealing surface.

[0024] Preferably, a cover plate is bolted to the inner side of the rotating surface, and the cover plate is fastened to the driving bevel gear.

[0025] Preferably, the end of the air outlet bracket is provided with a fixing frame, and the fixing frame is provided with several mounting holes.

[0026] Preferably, the end of the air outlet bracket away from the fixed frame is bent to form a contact surface, and several supporting ribs are provided between the contact surface and the outer side of the air outlet bracket.

[0027] On the other hand, according to an embodiment of the present invention, a cabinet air conditioner includes a housing, a lower air outlet channel and an upper air outlet channel disposed in the housing, a centrifugal fan disposed in the lower air outlet channel and the upper air outlet channel, and an air outlet mechanism, wherein the end of the lower air outlet channel or the end of the upper air outlet channel extends through the outside of the housing, and an air outlet bracket is disposed at the end of the lower air outlet channel or the end of the upper air outlet channel.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] By setting an air outlet bracket with a channel in the middle of the air conditioner, and configuring a rotatable soft-wind bracket inside the channel, combined with an adjustment mechanism to drive the sealing surface of the soft-wind bracket to rotate around the axis, the channel of the air outlet bracket can be dynamically blocked and opened. This allows for flexible switching between a concentrated direct blowing mode and a soft-wind diffusion mode according to user needs. When the sealing surface releases the blockage of the channel, the airflow is concentrated and ejected to meet the user's needs for strong wind speed and long-distance air delivery. When the sealing surface completely blocks the channel, the airflow is dispersed and guided to achieve gentle airflow from top to bottom, avoiding direct airflow to the human body, and significantly improving comfort.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0038] Because existing air conditioners use an up-and-down air outlet method, they cannot meet the requirement of direct airflow into the center. Therefore, this utility model embodiment proposes an air outlet mechanism, including:

[0039] The air outlet bracket 3 is located in the middle of the air conditioner and has a channel 301 that runs through both ends of it;

[0040] The gentle breeze bracket 4 is located in the channel 301 and includes two rotating surfaces 403 and a sealing surface 402 disposed between the two rotating surfaces 403. The two rotating surfaces 403 are respectively rotatably disposed on the inner side of the air outlet bracket 3.

[0041] An adjustment mechanism is provided on the air outlet bracket 3 and connected to one of the rotating surfaces 403. It is used to drive the sealing surface 402 to rotate around the rotating surface 403 as the axis, so as to seal or release the sealing of the opening of the channel 301.

[0042] In the embodiments of this utility model, such as Figure 2 and Figure 3 As shown, by setting an air outlet bracket 3 with a channel 301 in the middle of the air conditioner, the air conditioner can deliver air to the center through the channel 301. A rotatable soft-wind bracket 4 is configured inside the channel 301. Combined with an adjustment mechanism that drives the sealing surface 402 of the soft-wind bracket 4 to rotate around its axis, dynamic sealing and opening of the channel 301 of the air outlet bracket 3 is achieved. This allows for flexible switching between a concentrated direct blowing mode and a soft-wind diffusion mode according to user needs. When the sealing surface 402 is completely separated from the end of the channel 301, the sealing of the channel 301 is released, and the airflow is concentrated, meeting the user's needs for strong wind speed and long-distance air delivery. When the sealing surface 402 completely blocks the channel 301, the airflow is dispersed and guided, achieving gentle airflow from top to bottom and avoiding direct airflow onto the body, significantly improving comfort. The adjustment mechanism can be a handwheel structure for manual adjustment, or it can be replaced by other electric structures for automatic adjustment.

[0043] Based on the above scheme, in order to achieve automated adjustment, such as Figure 4 As shown, the adjustment mechanism is optimized. The adjustment mechanism is a first motor 5, which is located on the side of the air outlet bracket 3. The output end of the first motor 5 passes through the channel 301 and is connected to one of the rotating surfaces 403. By using the first motor 5 as the driving source, the user can open and close the channel 301 without manual operation. Specifically, with the controller and wireless module, the user can also remotely control it through mobile phones and other devices.

[0044] Based on the above solutions, such as Figure 5 and Figure 6 As shown, the air outlet mechanism also includes:

[0045] Mounting plate 401 is located at the bottom of sealing surface 402;

[0046] A plurality of soft wind blades 6, each of which is provided with a mounting shaft 603, and the plurality of mounting shafts 603 are rotatably mounted on the mounting plate 401 at intervals.

[0047] The drive assembly is located on the soft wind bracket 4 and connected to each mounting shaft 603, and is used to synchronously drive each mounting shaft 603 to rotate.

[0048] By setting an mounting plate 401 at the bottom of the sealing surface 402 and installing multiple soft wind blades 6 with independent mounting shafts 603 at intervals on it, the airflow can be further subdivided and guided, thereby decomposing the airflow in a single direction into multiple small airflows, effectively dispersing the wind force and improving the comfort of air delivery. At the same time, under the action of the drive component, each mounting shaft 603 can be driven to rotate synchronously, and the direction of airflow can be changed by changing the angle of the soft wind blades 6. When each mounting shaft 603 is driven to slowly rotate in both directions, the air sweeping function can be realized.

[0049] Specifically, the driver components include:

[0050] A plurality of transmission gears 601 are rotatably mounted on a mounting plate 401 and correspond one-to-one with a plurality of mounting shafts 603, and the mounting shafts 603 pass through the mounting plate 401 and are connected to the transmission gears 601.

[0051] A plurality of driven gears 602 are rotatably mounted on the mounting plate 401 and respectively mesh between two adjacent transmission gears 601;

[0052] The driving component is connected to one of the transmission gears 601.

[0053] By meshing several driven gears 602 between two adjacent transmission gears 601, when one of the transmission gears 601 is driven to rotate, it can drive all the other transmission gears 601 to rotate in the same direction, thereby achieving synchronous adjustment of the angle of all the soft wind blades 6. The driving component can be a motor or a motor structure. By mounting the motor on the sealing surface 402 and connecting it to one of the transmission gears 601, synchronous adjustment is achieved under the action of each driven gear 602.

[0054] Preferably, the structure of the driving component is optimized, and the driving component includes:

[0055] The sector bevel gear 7 is connected to one of the transmission gears 601;

[0056] The driving bevel gear 801 is rotatably disposed inside the rotating surface 403, and the driving bevel gear 801 meshes with the sector bevel gear 7;

[0057] The second motor 8 is located outside the rotating surface 403, and the output end of the second motor 8 is connected to the driving bevel gear 801.

[0058] Due to the limited installation space, the second motor 8 used for driving is installed on the side of the soft wind bracket 4, i.e., the rotating surface 403. The driving direction is reversed through the active bevel gear 801 and the sector bevel gear 7. When the second motor 8 rotates, the output end of the second motor 8 rotates, driving the active bevel gear 801, which in turn drives the sector bevel gear 7 to rotate. Since the sector bevel gear 7 is fixedly connected to one of the transmission gears 601, preferably the transmission gear 601 located at the very end, the sector bevel gear 7 can drive the transmission gear 601 to rotate. The axis of the transmission gear 601 and the axis of the sector bevel gear 7 are the same axis. Through the forward and reverse rotation of the second motor 8, the reciprocating oscillation of the soft wind blades 6 is achieved.

[0059] Specifically, for ease of installation and subsequent disassembly and maintenance, such as Figure 6 As shown, the mounting plate 401 is provided with several clips 404, which are all snapped onto the inner side of the sealing surface 402. The clips 404 are elastic structures, which not only ensure a tight connection between the mounting plate 401 and the sealing surface 402, but also allow the mounting plate 401 to be quickly removed by simply releasing the clips 404 when the soft wind blades 6 or the drive assembly need to be inspected, cleaned or replaced. At the same time, a cover plate 405 is bolted to the inner side of the rotating surface 403. The cover plate 405 is fastened to the active bevel gear 801. The cover plate 405 serves as a support and enclosure component for the active bevel gear 801, and achieves axial limitation of the active bevel gear 801. When it is necessary to replace or repair the internal components later, it is only necessary to remove the bolts and remove the cover plate 405.

[0060] Specifically, such as Figure 6 As shown, the end of the air outlet bracket 3 is provided with a fixing frame 9, and the fixing frame 9 is provided with several mounting holes 901. Through the several mounting holes 901 on the fixing frame 9, the air outlet mechanism can be easily and precisely aligned and firmly connected with the inside of the air conditioner, ensuring the stability of the air outlet mechanism after installation. At the same time, the air outlet mechanism can also be disassembled as a whole for convenient later maintenance.

[0061] Furthermore, the end of the air outlet bracket 3 away from the fixed frame 9 is bent to form an abutment surface 302. Several support ribs 303 are provided between the abutment surface 302 and the outer side of the air outlet bracket 3. The abutment surface 302 increases the contact area between the air outlet bracket 3 and the abutment position inside the air conditioner, ensuring stability. At the same time, under the action of the support ribs 303, the structural strength of the abutment surface 302 is increased, ensuring the stress-bearing effect of the abutment surface 302.

[0062] like Figure 1As shown, this utility model embodiment also proposes a cabinet air conditioner, including a housing 1, a lower air outlet channel 101 and an upper air outlet channel 102 disposed in the housing 1, a centrifugal fan 2 disposed in the lower air outlet channel 101 and the upper air outlet channel 102, and an air outlet mechanism. The end of the lower air outlet channel 101 or the end of the upper air outlet channel 102 extends through the outside of the housing 1, and the air outlet bracket 3 is disposed at the end of the lower air outlet channel 101 or the end of the upper air outlet channel 102. The air inlets of the cabinet air conditioner are located on the rear side of the casing 1, and there are two air inlets. The two air inlets correspond to the lower air outlet duct 101 and the upper air outlet duct 102, respectively. The bottom end of the lower air outlet duct 101 passes through the bottom of the casing 1, and the top end of the upper air outlet duct 102 passes through the top of the casing 1. When the two centrifugal fans 2 are driven, the air force generated by the centrifugal fans 2 is discharged through the top and bottom of the casing 1 to achieve upper and lower air outlet. In the design, the bottom end of the upper air outlet duct 102 or the top end of the lower air outlet duct 101 passes through the middle of the casing 1 to support the installation of the air outlet bracket 3. When the soft wind bracket 4 of the air outlet bracket 3 opens its end, the airflow generated by the lower air outlet duct 101 or the upper air outlet duct 102 is discharged through the air outlet bracket 3 to achieve upper, middle and lower exhaust and direct blowing.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
