[0025] See also Figure 1 and Figure 2 The embodiment of the utility model provides a cleaning mechanism 1, which is applied to an air conditioner. The air conditioner includes an air conditioner body 2. The air conditioner body 2 is provided with a drain port 21 and a drain pipe 22 connected to the drain port 21. The cleaning mechanism 1 includes a driving component 11, a transmission component 12 and a cleaning component 13. The driving component 11 and the transmission component 12 are both arranged in the air conditioner body 2. The driving component 11 drives the transmission component 12, and the cleaning component 13 is connected to the transmission component 12. The cleaning component 13 can reciprocate in the drain pipe 22 under the drive of the transmission component 12.

[0026] In this embodiment, a cleaning mechanism 1 is arranged on the air conditioner body 2, specifically at a position close to the drain port 21, so that the cleaning component 13 can extend into the drain pipe 22, and the cleaning component 13 is used to clean the dirt in the drain pipe 22, so that the drain pipe 22 can drain normally. The specific working principle of the cleaning mechanism 1 is: by starting the driving component 11 to drive the transmission component 12 to drive, and then drive the cleaning component 13 to reciprocate in the drain pipe 22, so as to clean the dirt in the drain pipe 22. The entire cleaning mechanism 1 solves the problem of dirt blockage in the drain pipe 22, so that the air conditioner can be used normally.

[0027] In a specific embodiment, Figure 1 As shown, the transmission assembly 12 is a connecting rod assembly, one end of the connecting rod assembly is connected to the driving assembly 11, and the cleaning assembly 13 is connected to the other end of the connecting rod assembly. Starting the driving assembly 11 can drive one end of the connecting rod assembly to rotate around the driving assembly 11, thereby driving the cleaning assembly 13 connected to the other end of the connecting rod assembly to reciprocate in the drain pipe 22 and clean the dirt. After cleaning for a certain period of time, the drain pipe 22 is flushed with condensed water collected by an external water source or a condensed water collection device to discharge the dirt and dirty water.

[0028] Specifically, Figure 1 As shown, the connecting rod assembly includes a first connecting rod 121 and a second connecting rod 122, one end of the second connecting rod 122 is hinged to one end of the first connecting rod 121, the other end of the second connecting rod 122 is connected to the cleaning assembly 13, and the other end of the first connecting rod 121 is hinged to the driving assembly 11.

[0029] In this embodiment, the driving assembly 11 drives the first connecting rod 121 to rotate, and then drives the second connecting rod 122 to move, thereby driving the cleaning assembly 13 to reciprocate in the drain pipe 22. By setting the connection between the driving assembly 11 and the connecting rod assembly and the connecting rod assembly and the cleaning assembly 13 to be hinged, a crank connecting rod movement mechanism is formed, so that the other end of the second connecting rod 122 performs a rotational telescopic movement, and then drives the cleaning assembly 13 to fit the inner wall of the drain pipe 22, so that the cleaning assembly 13 can rub more fully with the inner wall of the drain pipe 22, thereby achieving a better cleaning effect.

[0030] Since the cleaning mechanism 1 needs to be installed according to the position of the drain outlet 21, if there is no extra space near the drain outlet 21 to install the cleaning mechanism 1, the connecting rod assembly can be set as a multi-connecting rod assembly according to the distance between the installation position and the drain outlet 21, so that the cleaning assembly 13 can be smoothly extended into the drain pipe 22.

[0031] Specifically, the driving assembly 11 includes a driving base, a driving shaft and a driving member all disposed on the driving base. The driving member can drive the driving shaft to rotate, and the other end of the first connecting rod 121 is hinged to the driving shaft.

[0032] In this embodiment, the driving assembly 11 includes a driving base, a driving shaft and a driving member. The driving base is installed at a position close to the drain outlet 21 to facilitate the cleaning assembly 13 to extend into the drain pipe 22. The driving shaft is arranged on the driving base and connected to the other end of the first connecting rod 121. When the driving member drives the driving shaft to rotate, the driving shaft can drive the first connecting rod 121 to rotate around the driving shaft in the corresponding direction. Figure 1 As shown in the direction of the rotating arrow, the second connecting rod 122 is then driven to move, thereby driving the cleaning assembly 13 to move.

[0033] In addition, a rotating mechanism may be added between the other end of the second connecting rod 122 and the cleaning assembly 13. The rotating mechanism may have its own driving device, or may be driven by a driving member. The rotating mechanism drives the cleaning assembly 13 to rotate (e.g., 360°) about the central axis of its own length direction, so that the pipeline can be cleaned in all aspects at a more fitting angle in the pipeline of the drain pipe 22, thereby improving the cleaning efficiency. In this embodiment, the cleaning assembly 13 should be set to a wider shape so that it can fit the inner wall of the drain pipe 22 for cleaning.

[0034] In other embodiments, another rotating mechanism may be added between the other end of the second connecting rod 122 and the cleaning assembly 13. The rotating mechanism may have its own driving device, or may be driven by a driving member. The rotating mechanism drives the cleaning assembly 13 to move in a circle (e.g., a 360° circle) with the central axis of its own length direction as the axis. During the circular motion, the cleaning assembly 13 may fit the inner wall of the drain pipe 22, so that the pipe can be cleaned in all aspects at a more fitting angle in the pipe, thereby improving the cleaning efficiency. In this embodiment, the cleaning assembly 13 should be set to a narrower shape so that it can fit the inner wall of the drain pipe 22 for cleaning.

[0035] In this embodiment, the driving component 11 is provided so that the air conditioner can control the cleaning mechanism 1 to work, and the automatic cleaning of the drain pipe 22 can be realized without the need for professionals, thereby improving the cleaning efficiency.

[0036] In a specific embodiment, the cleaning component 13 is a retractable structure, and the transmission component 12 can drive the cleaning component 13 to retract in the drain pipe 22 .

[0037] In this embodiment, the cleaning component 13 may include multiple telescopic arms, which are arranged in sequence. When it is necessary to retract, the other telescopic arms can be retracted in sequence from front to back in the bottom telescopic arm. When it is necessary to extend, the other telescopic arms can be extended from the bottom telescopic arm in sequence from back to front. The above-mentioned extension and retraction actions can be driven by the driving component 11 driving the transmission component 12, and then the transmission component 12 drives the telescopic arm to extend and retract. Compared with the aforementioned connecting rod component, the telescopic cleaning component 13 saves more space and can also achieve a better cleaning effect.

[0038] In a specific embodiment, the length of the cleaning component 13 is adapted to the length of the drain pipe 22 (this adaptation does not mean that the length is completely consistent, as long as it meets the cleaning requirements), and the cleaning component 13 is divided into multiple telescopic arms according to the predetermined length according to the length of the cleaning component 13, and each telescopic arm cooperates with each other to correspond to different positions of the drain pipe 22, and then multiple detectors are installed in the wall of the drain pipe 22 (the detectors are described in detail below). If the detector at a certain position detects dirt, the cleaning component 13 is controlled to extend multiple telescopic arms matching the dirt position into the drain pipe 22 to clean the dirt. It should be noted that if dirt is detected at multiple positions in the drain pipe 22, the distance from the position where the dirt appears to the cleaning component 13 is the farthest, and then the corresponding number of telescopic arms are controlled to extend.

[0039] Specifically, the cleaning component 13 is made of soft material.

[0040] In this embodiment, in order to make the cleaning component 13 fit with the drain pipe 22 during the reciprocating motion, the cleaning component 13 is preferably set to a soft material, which is convenient for removing dirt at any position of the drain pipe 22 and improving the cleaning effect. In particular, in the scenario where the transmission component 12 is a connecting rod component, since the cleaning component 13 does not move linearly at this time, it is necessary to set the cleaning component 13 to a soft material so as to increase the activity space of the cleaning component 13 and meet the cleaning requirements.

[0041] Specifically, the cleaning component 13 is a metal wire structure.

[0042] In the present embodiment, it can be known from the foregoing embodiments that the cleaning component 13 can be set as a retractable structure, and the transmission component 12 can be set as a connecting rod assembly. Regardless of the scenario of the retractable structure or the connecting rod assembly, when the cleaning component 13 is not working, in order to save space, the cleaning component 13 is usually placed on one side of the drain pipe 22 (that is, all or most of the cleaning component 13 is located in the drain pipe 22). At this time, the size of the cleaning component 13 cannot affect the normal use of the drain pipe 22. The cleaning component 13 needs to be set as a small structure that can clean dirt. Therefore, it is preferred to set the cleaning component 13 to a metal wire structure. Moreover, due to the ductility of the metal, it is convenient for the cleaning component 13 to reciprocate in the drain pipe 22.

[0043] In a specific embodiment, the cleaning component 13 can be made into a brush shape using metal wire, and a thorn-like structure is provided on the periphery of the cleaning component 13, so that the cleaning component 13 can scrub dirt more labor-savingly through the thorn-like structure, so as to better clean the inner wall of the drain pipe 22. However, since the cleaning component 13 is provided with a thorn-like structure on the surface, the drain pipe 22 is easily worn out by using the cleaning component 13 to clean the inner wall of the drain pipe 22 many times, and even worn out in severe cases, causing the drain pipe 22 to leak, so it is necessary to inspect and maintain the inner wall of the drain pipe 22 at predetermined intervals, or install a protective layer on the inner wall of the drain pipe 22 to prevent the drain pipe 22 from being damaged, so as not to affect the subsequent use of other functions of the air conditioner. In addition, the cleaning component 13 can also be set as a plurality of metal wire-like structures, so that the contact area between the cleaning component 13 and the drain pipe 22 can be increased, thereby improving the cleaning effect.

[0044] In addition, a bending sensor can be provided in the drain pipe 22, and the bending sensor can monitor the bending state of the thorn-like structure in real time to prevent the cleaning component 13 from being overused, thereby reducing the cleaning effect. If the friction between the cleaning component 13 and the pipe wall causes the shape of the thorn-like structure to change from upright to curved, it is determined that the cleaning component 13 is overused, and it is necessary to contact a professional to replace the cleaning component 13. In a specific embodiment, the connection between the connecting rod assembly and the cleaning component 13 can be set as a detachable connection, which is convenient for disassembly and replacement of the cleaning component 13, so that the cleaning mechanism 1 always maintains a high cleaning ability.

[0045] It should be noted that the cleaning component 13 is prone to rust after being immersed in water for a long time, and needs to be checked and replaced at regular intervals. A protective layer can also be provided on the outer layer of the cleaning component 13 to extend the service life of the cleaning component 13.

[0046] like Figure 2 As shown, an embodiment of the utility model further provides an air conditioner, which includes an air conditioner body 2, on which a drain outlet 21 and a drain pipe 22 connected to the drain outlet 21 are provided, and the air conditioner also includes the cleaning mechanism 1 as described above.

[0047] In this embodiment, the cleaning mechanism 1 is arranged near the drain port 21, the drain port 21 is connected to the drain pipe 22, and the cleaning assembly 13 extends into the drain pipe 22 through the drain port 21 for cleaning. Figure 2 It can be seen that the drain pipe 22 is relatively long, so the cleaning component 13 also needs to be set as a metal wire with a relatively long structure, so that the cleaning component 13 can clean most of the dirt in the drain pipe 22, so that the drain pipe 22 can drain normally.

[0048] In addition, a condensate collection device can be provided on the air conditioner body 2. After the cleaning mechanism 1 has cleaned for a period of time, the condensate collection device is started to collect condensate, and the condensate is used to flush the dirt scrubbed off the drain pipe 22, so that the dirt flows out of the drain pipe 22 to avoid blockage of the drain pipe 22.

[0049] Specifically, the air conditioner further includes a detection component 23 for detecting whether the drain pipe 22 is blocked. The detection component 23 is arranged in the drain port 21 and / or the drain pipe 22 .

[0050] In this embodiment, in order to quickly solve the blockage problem of the drain pipe 22, a detection component 23 is preferably set in the drain outlet 21 and / or the drain pipe 22. The detection component 23 and the cleaning mechanism 1 are both communicatively connected to the main control device of the air conditioner. When the detection component 23 detects that the drain pipe 22 is blocked, the air conditioner starts the cleaning mechanism 1 to clean the drain pipe 22, thereby improving the cleaning efficiency and preventing the blockage problem of the drain pipe 22 to a certain extent.

[0051] In a specific embodiment, the detection component 23 is a water flow sensor for detecting the water flow velocity, which can be arranged at the drain outlet 21 or in the drain pipe 22. If the water flow sensor detects that the water flow velocity slows down, it means that the drain pipe 22 is blocked, and at this time, the cleaning mechanism 1 is started; if the water flow velocity is normal, it means that there is no abnormality in the drain pipe 22, and the air conditioner can be used normally. In addition, the detection component 23 can also be set as a pressure sensor, which can be installed on the drain pipe 22 to monitor the pressure change in the pipe, so as to judge the thickness of the dirt in the drain pipe 22. If it is detected that the pressure in the drain pipe 22 increases and the dirt thickness exceeds a predetermined value, it means that the drain pipe 22 is blocked; if it is detected that the pressure in the drain pipe 22 decreases and the dirt thickness is lower than a predetermined value, it means that there is no abnormality in the drain pipe 22, and the air conditioner can be used normally.

[0052] In a specific scenario, the detection component 23 can also be set as an ultrasonic sensor and an optical sensor, both of which can detect the thickness of dirt in the drain pipe 22. Specifically, the ultrasonic sensor detects the thickness of dirt in the drain pipe 22 by sending ultrasonic waves and measuring the time of echoes, and the optical sensor detects the thickness of dirt in the drain pipe 22 by sending light beams and measuring the changes in light intensity. Among them, the optical sensor is more suitable for transparent or translucent drain pipes 22.

[0053] It should be noted that, whether the detection component 23 is set as a water flow sensor or other sensors such as a pressure sensor, in order to prevent dirt and particles from entering the sensor, a protective cover can be installed outside the sensor to avoid affecting the accuracy of the sensor.

[0054] In a specific embodiment, a timing device and an alarm device connected to the air conditioner main control device can also be set in the air conditioner body 2. The timing device and the alarm device are both connected to multiple sensors for communication. The timing device sets corresponding instructions for each sensor. When the corresponding instruction is received, the alarm device is used to alarm and send professionals to perform corresponding maintenance. For example, a water leakage sensor is set on the drain pipe 22. The sensor detects whether the drain pipe 22 is leaking by sound or humidity, thereby judging the health status of the drain pipe 22. The sensor effectively prevents excessive friction between the cleaning component 13 and the inner wall of the drain pipe 22, which may cause the drain pipe 22 to rupture.

[0055] 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.
