[0002] At present, most of the air-conditioning fans on the market are installed inside the air conditioner and fixed by fasteners. A grille is installed in front of the fan for protection, and the grille is also fixed by fasteners. When the user needs to repair the fan or clean the fan blades, the grille needs to be manually removed and the air conditioner power supply needs to be disconnected. When the fan is in the state inside the air conditioner, personnel perform operations such as repairing or cleaning the fan or the fan blades, which is extremely inconvenient, time-consuming and laborious; in order to overcome the above deficiencies, in the related art, the fan assembly is arranged on the sliding assembly so that the fan assembly can be pulled out from inside the air conditioner when the fan needs to be maintained. This method requires the operator to first remove the corresponding fan grille, and then pull out the fan assembly manually. The assembly of the fan grille mostly uses threaded fasteners at the four corners. On the one hand, the operation of screwing the threaded parts is not convenient and time-consuming, and on the other hand, frequent disassembly and assembly are likely to cause the occurrence of thread slipping, resulting in after-sales complaints.

Detailed implementation manners

[0031] Combined with reference to Figure 1 and Figure 8As shown, according to an embodiment of the present invention, an outdoor unit of an air conditioner is provided, including a housing (not shown in the figure). The housing forms a blower accommodation space, and a blower module 2 is accommodated in the blower accommodation space. The blower module 2 specifically includes a blower impeller and a motor for driving the blower impeller to rotate. The blower accommodation space has an opening (not labeled in the figure) on the maintenance side (i.e., the side that facilitates the user or operator to maintain the blower module 2), and further includes a blower grille 31 and an opening / closing driving device 4. The blower grille 31 is configured with a flow-through grille and a wind guiding ring (not labeled in the figure). The opening / closing driving device 4 is connected to the first side of the blower grille 31. The opening / closing driving device 4 is specifically fixedly assembled on a corresponding carrier component. The aforementioned carrier component can be, for example, the aforementioned housing or a separate assembly bracket fixed to the housing. The present invention does not particularly limit it. The blower grille 31 can rotate towards or away from the opening under the drive of the opening / closing driving device 4 to block and open the opening, thereby realizing the switching of the open or closed position of the blower grille 31. In addition, it is worth noting that the blower grille 31 automatically opens the aforementioned opening in a flipping and opening manner, which can make full use of the overhanging space on the outer side of the building, reduce the dimensional requirements of the installation space for the outdoor unit of the air conditioner, and further reduce the risk of interference with the installation structure.

[0032] In this technical solution, the opening / closing driving device 4 can drive the blower grille 31 to open or close. Specifically, when it is necessary to maintain or clean the blower module 2, control the opening / closing driving device 4 to operate to drive the blower grille 31 to open. After the maintenance or cleaning is completed, control the opening / closing driving device 4 to operate in the reverse direction to drive the blower grille 31 to close. During the process, there is no need to disassemble the thread, thus eliminating the problems of inconvenient operation and low efficiency caused by disassembling the thread and the thread slipping caused by repeated disassembly.

[0033] In a specific embodiment, the opening / closing driving device 4 includes a rotary motor. The output rotating shaft of the rotary motor is fixedly connected to the blower grille 31. Specifically, for example, a socket block is provided on the first side of the blower grille 31, and the socket block is fixedly sleeved on the output rotating shaft, so that the rotation of the output rotating shaft drives the rotation of the blower grille 31 to achieve the purpose of opening and closing. In a preferred embodiment, the rotary motor is a double-ended output shaft motor, that is, the rotating shaft of the rotary motor extends out of the end covers at both ends of the motor housing. At this time, two socket blocks are provided, and the two socket blocks are respectively sleeved on both ends of the double-ended output shaft. In this way, the blower grille 31 is fixedly connected to the double-ended output shaft of the double-ended output shaft motor, and thus the rotary motor can more reliably and stably control the opening and closing of the blower grille 31. The aforementioned rotary motor is preferably a motor with a built-in brake structure (also called a locking structure) to be able to keep the rotating shaft stationary when the motor does not operate, thereby realizing the control of the opening angle position of the blower grille 31, and at the same time, the position reliability of the blower grille 31 in the closed position can also be realized.

[0034] In another embodiment, referring to Figure 4 as shown, a lower positioning detection piece 311 is provided on the first end of the double-ended output shaft for determining the position when the fan grille 31 blocks the opening; and / or, an upper positioning detection piece 312 is provided on the first end of the double-ended output shaft for determining the position when the fan grille 31 opens the opening. In this technical solution, the lower positioning detection piece 311 and the upper positioning detection piece 312 respectively correspond to the closed state and the open state of the fan grille 31. Specifically, they form pairs with corresponding proximity sensors. When the corresponding positioning detection piece moves to the corresponding proximity sensor following the rotation of the rotating shaft, the proximity sensor will be triggered to form a corresponding signal and transmit it to the corresponding control system, such as Figure 3 the control component 8 shown in

[0035] and then, via the control component 8, the rotation of the rotating motor is controlled to stop, so that the fan grille 31 stops at the corresponding limited position, realizing precise motion control of the fan grille 31. In a specific embodiment, the aforementioned lower positioning detection piece 311 specifically corresponds to the position where the angle between the fan grille 31 and the vertical plane is 0°, and the aforementioned upper positioning detection piece 312 specifically corresponds to the position where the angle between the fan grille 31 and the vertical plane is 120°.

[0036] Referring to in combination Figure 1 、 Figure 6 and Figure 7 , in another preferred embodiment, the outdoor unit of the air conditioner further includes a magnetic locking device. The magnetic locking device includes a locking member 32 connected to the second side of the fan grille 31, a blocking member 33 rotatably connected to the base 1 of the housing, and an electromagnetic member 34 fixedly connected to the housing. The aforementioned second side and the aforementioned first side are respectively the bottom side and the top side of the fan grille 31 in the closed state. The blocking member 33 has a locking position under the magnetic attraction of the electromagnetic member 34 and an unlocking position where the magnetic attraction with the electromagnetic member 34 is released. When the blocking member 33 is in the locking position, the blocking member 33 restricts the displacement of the locking member 32. When the blocking member 33 is in the unlocking position, the blocking member 33 does not restrict the displacement of the locking member 32. In this technical solution, the position locking of the fan grille 31 can be realized by the setting of the magnetic locking device. Fixing the fan grille 31 in this way can further avoid the disadvantages of low efficiency and inconvenient operation brought by the method of using threaded connection to fix it in the prior art.

[0037] See Figure 6 As shown, the base 1 in this figure shows the situation in the use state, where the locking member 32 is vertically connected to the bottom side of the fan grille 31, and the blocking member 33 and the electromagnetic member 34 are arranged at intervals from each other. When it is necessary to lock the fan grille 31, the locking member 32 will be in the aforementioned interval. At this time, the electromagnetic member 34 is controlled to be energized to generate a magnetic force, and at least part of the blocking member 33 can be attracted by the aforementioned magnetic force, so as to realize the rotation of the blocking member 33 under the suction force and be adsorbed and attached to the electromagnetic member 34, thus realizing the position locking of the blocking member 33 to the locking member 32. In one embodiment, a torsion spring is provided between the blocking member 33 and the base 1, and the unlocking and resetting of the blocking member 33 can be realized by the torsion force of the torsion spring when the electromagnetic member 34 is powered off and demagnetized. In another more optimal embodiment, when the electromagnetic member 34 is powered off and demagnetized, the blocking member 33 rotates relative to the housing under its own weight. At this time, it is necessary for the blocking member 33 to be rotatable relative to the housing in the vertical plane, and thus the structural design can be realized. The aforementioned magnetic locking device can be provided with two, and the two magnetic locking devices are arranged at intervals along the horizontal direction.

[0038] The outdoor unit of the air conditioner further includes a control switch 6. The control switch 6 has a first trigger state and a second trigger state. When the control switch 6 is in the first trigger state, the power supply of the fan module 2 is disconnected. When the control switch 6 is in the second trigger state, the power supply of the fan module 2 is connected. Further, the outdoor unit of the air conditioner further includes a fan position switching driving device 5. When the control switch 6 is in the first trigger state, the opening and closing driving device 4 drives the fan grille 31 to rotate away from the opening to open the opening, and the fan position switching driving device 5 drives the fan module 2 to move out of the fan accommodation space. When the control switch 6 is in the second trigger state, the opening and closing driving device 4 drives the fan grille 31 to rotate towards the opening to block the opening, and the fan position switching driving device 5 drives the fan module 2 to move back into the fan accommodation space. The aforementioned control switch 6 can specifically be a control button. At this time, the first trigger state is on, and the corresponding second trigger state is off. In this technical solution, when it is necessary to maintain the fan module 2, the user or operator operates (such as pressing) the control switch 6 to realize the switching of different control instructions, and thus the maintenance and cleaning of the fan are very convenient. It should be particularly noted that in the present invention, the on-off of the power supply of the fan module 2 is automatically controlled and switched through the trigger state of the control switch 6, which can effectively prevent the occurrence of electric shock hazards during the maintenance process of the fan module 2.

[0039] In a specific embodiment, the fan position switching drive device 5 includes a screw motor. The fan module 2 is assembled on the fan bracket 21. The rotation of the screw 51 can drive the fan bracket 21 to move linearly. Specifically, a threaded sleeve is fixedly connected to the fan bracket 21, and the threaded connection with the screw 51 is achieved through this threaded sleeve. The movement drive of the fan bracket 21 by the threaded connection drive method is more accurate and reliable, and the self-locking characteristic of the threaded connection can be used to position the position of the fan module 2, preventing the position change of the fan module 2 during maintenance or cleaning. For specific reference, see Figure 5 As shown, the fan position switching drive device 5 includes a device housing 52. The screw motor is placed inside the device housing 52. Along the extending length direction of the screw of the screw motor, fan movement detection plates are respectively arranged at the front end and the rear end of the linear movement path inside the device housing 52, and the precise positioning of the displacement drive of the fan position switching drive device 5 is achieved through the fan movement detection plates.

[0040] In another preferred embodiment, the outdoor unit of the air conditioner further includes a linear sliding component 7. The linear sliding component 7 is connected between the fan bracket 21 and the base 1 of the housing, and the sliding guiding direction of the linear sliding component 7 is parallel to the driving movement direction of the screw motor. Specifically, the fan position switching drive device 5 and the linear sliding component 7 are respectively located at the top and the bottom of the fan bracket 21, so as to form precise and stable movement control for the extension and retraction of the fan module 2.

[0041] According to the embodiment of the present invention, a control method for the outdoor unit of an air conditioner is further provided, which is used to control the above-mentioned outdoor unit of the air conditioner, and includes the following steps:

[0042] Obtain the trigger state of the control switch 6;

[0043] Control the running directions of the opening and closing drive device 4 and the fan position switching drive device 5 according to the obtained trigger state.

[0044] Specifically, when the obtained trigger state is the first trigger state, control the opening and closing drive device 4 to operate to drive the fan grille 31 to switch from the blocking position to the open position, and control the fan position switching drive device 5 to operate to drive the fan module 2 to move out of the fan accommodation space; or,

[0045] When the obtained trigger state is the second trigger state, control the opening and closing drive device 4 to operate to drive the fan grille 31 to switch from the open position to the blocking position, and control the fan position switching drive device 5 to operate to drive the fan module 2 to move back into the fan accommodation space.

[0046] In some embodiments, when the trigger state is the first trigger state, the operation of the fan position switching drive device 5 is after the opening and closing drive device 4 operates to drive the fan grille 31 to the open position, so as to prevent interference between the extension of the fan module 2 and the fan grille 31. Or, when the trigger state is the second trigger state, the operation of the opening and closing drive device 4 is after the fan position switching drive device 5 operates to drive the fan module 2 to move and retract in place, so as to prevent interference between the closing fan grille 31 and the retracting fan module 2.

[0047] In another preferred embodiment, when a magnetic locking device is included and the trigger state is the first trigger state, the electromagnetic member 34 of the magnetic locking device is powered off before controlling the operation of the opening and closing drive device 4; or, when a magnetic locking device is included and the trigger state is the second trigger state, the electromagnetic member 34 of the magnetic locking device is powered on after the fan grille 31 is switched to the shielding position. In this way, the locking and unlocking of the magnetic locking device are matched with the operation purpose of the operator. In a preferred embodiment, the power-off of the electromagnetic member 34 occurs simultaneously when the control switch 6 is controlled to be in the first trigger state, while the power-on of the electromagnetic member 34 occurs with a time delay when the control switch 6 is controlled to be in the second trigger state. The aforementioned time delay should ensure that the fan grille 31 is already in the shielding position. Thus, in the present invention, only by controlling the state switching of the aforementioned control switch 6 can the extension and retraction of the fan module 2 be realized, thereby making the maintenance of the fan very convenient and achieving one-key operation.

[0048] The following further elaborates on the technical solution of the present invention in conjunction with a specific operation example as Figure 8 shown.

[0049] When the control switch 6 (specifically, it can be a differential pressure switch, as Figure 8 shown) is turned on, the controller (i.e., the control component 8 mentioned above, the same below) disconnects the air conditioner power supply. At the same time, the electromagnet (i.e., the electromagnetic member 34 mentioned above, the same below) in the fan grille locking and opening module (i.e., the magnetic locking device mentioned above, the same below) loses magnetic force, and the device loses the locking function, and the fan grille is in a rotatable state; the controller controls the operation of the fan grille drive module (i.e., the opening and closing drive device 4 mentioned above, the same below), and the motor (i.e., the rotary motor mentioned above) drives the fan grille to move and rotate it by 120° (as Figure 3As shown, after the fan grille rotates 120°, the 120° rotation detection plate of the fan grille (i.e., the upper positioning detection piece 312 mentioned above) feeds back to the controller, and the controller controls the fan grille drive module to stop running, and the rotation action of the fan grille is completed; the controller controls the fan drive module (i.e., the fan position switching drive device 5 mentioned above, the same below) to run, and the power is provided by the stepping motor (i.e., the screw motor mentioned above) to make the fan assembly (i.e., the fan module 2 mentioned above) move on the screw and the fan slide rail (i.e., the linear sliding assembly 7). After the fan assembly moves 300 mm outward from the air conditioner as Figure 3 shown, the fan movement detection plate feeds back to the controller, and the controller controls the fan drive module to stop running, and the fan pushing action is completed.

[0050] When the control switch is turned off, the controller controls the fan drive module to run, so that the fan assembly moves 0 mm inward to the air conditioner (the position where the fan assembly is located when the air conditioner is running normally) as Figure 2 shown, the fan movement detection plate feeds back to the controller, and the controller controls the fan drive module to stop running; then the controller controls the fan grille drive module to run, so that the fan grille rotates downward close to the air conditioner to 0° (the position where the fan grille is located when the air conditioner is working normally) as Figure 2 shown, the 0° rotation detection plate of the fan grille (i.e., the lower positioning detection piece 311 mentioned above) feeds back to the controller, and the controller controls the fan grille drive module to stop running; the controller controls the air conditioner to be powered on, so that the electromagnet of the fan grille locking and opening module obtains magnetic force, attracts the iron blocking block (i.e., the blocking piece 33) to stick tightly, the device plays a locking role, the fan grille obtains a fastening effect, and the fan recovery action is completed.

[0051] It is easy for those skilled in the art to understand that, on the premise of no conflict, the advantageous technical features of the above various methods can be freely combined and superimposed.

[0052] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
