Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to a cleaning device, an outdoor unit of an air conditioner, and a cleaning control method. Background Art

[0002] The main function of the outdoor unit of an air conditioner is to transfer the heat indoors to the outdoors through a refrigerant and dissipate the heat into the atmosphere through a condenser. The condenser generally consists of multiple metal fins, and a fan is used to enhance air flow to improve the heat dissipation efficiency. However, after long-term operation, a large amount of dust will accumulate on the surface of the condenser, affecting the heat dissipation effect, resulting in a decrease in the efficiency of the air conditioner, an increase in energy consumption, and even possible equipment failures.

[0003] Currently, the dust removal methods for the outdoor unit of an air conditioner mainly include manual cleaning and automatic cleaning systems. Manual cleaning usually requires users to regularly turn off the power and use tools such as brushes, vacuum cleaners, or water guns for cleaning, which is time-consuming and laborious, and is prone to poor heat dissipation due to incomplete cleaning. Although the automatic cleaning system can reduce manual intervention, the existing systems are usually based on a fixed cleaning cycle and cannot be dynamically adjusted according to the actual dust accumulation situation. There may be cases where dust removal is not started when there is too much dust or the dust removal function is misactivated in a dust-free state. Summary of the Invention

[0053] Such as Figures 1 to 5 , an embodiment of the present invention provides a cleaning device for cleaning the condenser 3 of an air conditioner outdoor unit, including:

[0054] A skeleton 11, mounted on the air conditioner outdoor unit and located outside the condenser 3;

[0055] A cleaning assembly 12, slidably mounted on the skeleton 11 and capable of moving and cleaning on the outer surface of the condenser 3;

[0056] The cleaning assembly 12 includes a cleaning roller 121 and a driving member. The cleaning roller 121 is movably mounted on the skeleton 11; the driving member is mounted on the skeleton 11 and is used to drive the cleaning roller 121 to perform moving cleaning on the outer surface of the condenser 3;

[0057] A pressure detection assembly, arranged on the air conditioner outdoor unit and located inside and outside the condenser 3, for detecting the pressure difference between the inside and outside of the condenser 3;

[0058] A vibration assembly, arranged on the cleaning assembly 12, and the vibration function is turned on when the pressure difference reaches a preset threshold.

[0059] In this embodiment, the skeleton 11 can be a metal frame, which has sufficient strength and stability to support the cleaning component 12 to slide outside the condenser 3 of the outdoor unit of the air conditioner. At the same time, the material of the skeleton 11 also needs to have a certain corrosion resistance to adapt to the changes in the outdoor environment. The cleaning component 12 can perform reciprocating motion to clean the outside of the condenser 3 (i.e., the heat dissipation fins of the condenser 3) back and forth. The pressure detection component can detect the pressure difference between the inside and outside of the condenser 3. The more dust there is on the outside and the more serious the blockage is, the greater the pressure difference will be. The vibration component has a vibration function. When the vibration component starts the vibration function, it will cause the cleaning component 12 to vibrate, thereby improving the cleaning ability of the cleaning component 12.

[0060] More specifically, the pressure difference between the inside and outside of the condenser 3 can be regularly collected by the pressure detection component. When the pressure difference does not reach the preset threshold, it indicates that the dust amount is small and does not affect heat dissipation, so there is no need to clean. When the pressure difference reaches the preset threshold, it indicates that the dust amount has reached the level that affects heat dissipation and cleaning is required. During the cleaning process, the cleaning component 12 and the vibration component can be enabled at the same time. At this time, under the drive of the driving component, the cleaning roller 121 can move smoothly on the outer surface of the condenser 3, thereby cleaning the dust on the outer surface of the condenser 3, and cooperating with the vibration function of the vibration component to improve the cleaning effect, effectively cope with the situation of too thick dust accumulation, improve the cleaning effect, and further ensure the heat dissipation ability of the condenser 3.

[0061] In one embodiment, the moving mode of the cleaning roller 121 can be set to perform translational and rolling motions at the same time. The driving component can adopt a motor drive structure, and the driving component can drive the cleaning roller 121 to perform translational and rolling motions on the outer surface of the condenser 3. The specific implementation method is as follows:

[0062] In some implementation methods, the driving component can include: a driving motor 122, a driving wheel 124, and a transmission belt 123. The driving motor 122 is installed on the skeleton 11. The driving wheel 124 is installed at the output end of the driving motor 122. The transmission belt 123 is sleeved on the driving wheel 124. One end of the cleaning roller 121 is connected to the transmission belt 123, and the other end of the cleaning roller 121 is slidably limited on the slide rail 112 provided on the skeleton 11. In this way, by driving the driving wheel 124 to rotate by the driving motor 122, the transmission belt 123 can be driven to transmit, and then the cleaning roller 121 can be driven to perform translational and rolling motions on the skeleton 11.

[0063] In some preferred examples, two driving motors 122 and two driving wheels 124 can be used. The two driving motors 122 are installed at both ends of one side of the skeleton 11. The two driving wheels 124 are respectively installed at the output ends of the two driving motors 122. The transmission belt 123 is sleeved on the two driving wheels 124.

[0064] In this implementation, in order to clean the condenser 3 more effectively, a motion mechanism needs to be designed to drive the cleaning roller 121 to move stably to achieve the cleaning function. This implementation adopts a belt drive method (such as a leather belt). The cleaning roller 121 is driven to rotate by the driving wheel 124 and the transmission belt 123. One end of the cleaning roller 121 obtains power through the transmission belt 123, and the other end of the cleaning roller 121 is stably slidably limited on the slide rail 112 of the framework 11, ensuring that the cleaning roller 121 can move back and forth on the framework 11 while rolling smoothly, so as to achieve a comprehensive cleaning of the condenser 3.

[0065] In addition, by adjusting the rotation speed of the driving motor 122, the movement speed and force of the cleaning roller 121 can be further controlled to meet the cleaning requirements in different scenarios.

[0066] In some other embodiments, bristles are provided on the outer peripheral surface of the cleaning roller 121, and the bristles can effectively remove dust and dirt on the outer surface of the condenser 3.

[0067] In one embodiment, a first clamping portion 111 is provided on the framework 11, and a second clamping portion 27 is provided on the housing 2 of the outdoor unit of the air conditioner. The first clamping portion 111 and the second clamping portion 27 are used for clamping and cooperating with each other so that the framework 11 is clamped to the housing 2.

[0068] In this embodiment, the shape of the framework 11 can be rectangular, and the first clamping portion 111 can be two buckles provided on both sides of the framework 11. The housing 2 is composed of structures such as a top cover 21, a panel 22, a left side plate 23, a right side plate 24, and a chassis 25. Two buckles can be provided on the left side plate 23 and the right side plate 24. Based on this, through the snap-in installation of the first clamping portion 111 and the second clamping portion 27, the overall assembly of the cleaning device 1 is realized, and then it is reinforced with screws to ensure the installation stability of the cleaning device 1.

[0069] The framework 11 of this embodiment can solve the problems of the placement position and installation of the entire cleaning device 1 on the outdoor unit of the air conditioner. The external cleaning device 1 does not occupy the internal space and does not affect the performance of the outdoor unit of the air conditioner. Moreover, the framework 11 can be installed according to requirements, which is convenient for operation and also convenient for the maintenance and replacement of the cleaning device 1.

[0070] As Figure 6 shown, in one embodiment, the pressure detection component includes a first pressure sensor 13 and a second pressure sensor 14; the first pressure sensor 13 is installed on the outdoor unit of the air conditioner and is located inside the condenser 3, and the first pressure sensor 13 is used to detect the pressure inside the condenser 3; the second pressure sensor 14 is installed on the outdoor unit of the air conditioner and is located outside the condenser 3, and the second pressure sensor 14 is used to detect the pressure outside the condenser 3.

[0071] In this embodiment, in order to better clean the condenser 3 under different conditions, a detection and control function is designed to intelligently clean the condenser 3 under different conditions (i.e., different dust amounts). Specifically, this embodiment is designed with two pressure sensors, which can be assembled on the motor bracket 26 of the outdoor unit of the air conditioner and are located outside and inside the condenser 3 respectively. The internal pressure P1 and external pressure P2 of the condenser 3 are monitored through the pressure sensors. When there is a lot of dust in the condenser 3 and the blockage is serious, the value of the internal and external pressure difference △P = P1 - P2 increases, and vice versa. Through this principle, the pressure values P1 and P2 are collected and fed back by the first pressure sensor 13 and the second pressure sensor 14, and the controller calculates the pressure difference △P to know the dust amount, providing a judgment basis for subsequent cleaning. That is, when the detected pressure difference △P reaches the preset threshold, the cleaning component 12 and the vibration component need to be enabled to perform the cleaning work.

[0072] In addition, this embodiment is also designed with an intelligent reminder function. When it is detected that the condenser 3 needs to be cleaned, it is prompted through an indicator light or a buzzer, etc.

[0073] As Figure 7 shown, in one embodiment, the vibration component includes: a permanent magnet 15, two limiting cavities 16, and a plurality of energized coils 17; the permanent magnet 15 is arranged inside the cleaning drum 121 and can rotate; the two limiting cavities 16 are fixed on the cleaning drum 121 and are respectively sleeved at both ends of the permanent magnet 15 to limit the rotation range of the permanent magnet 15; the plurality of energized coils 17 are arranged on the cleaning drum 121 and are distributed around the permanent magnet 15.

[0074] In this embodiment, when different energized coils 17 are energized, due to the different magnetic field directions generated by the electro-magnetic induction, the directions of the forces received by the permanent magnet are different. When different two coils are alternately energized, the direction of the force received by the permanent magnet also changes periodically with the different energized coils 17, so that the permanent magnet will perform forward and reverse rotational movements under the limitation of the limiting cavity 16 and will have small-amplitude and high-speed impacts with the limiting cavity 16. Since the permanent magnet 15 is installed on the cleaning drum 121, the rotational impact of the permanent magnet 15 will cause the cleaning drum 121 to vibrate, which can solve the problem that the dust adhesion force is too large to be cleaned, enhance the cleaning strength, and increase the reliability of cleaning.

[0075] In addition, based on the aforementioned obtained pressure difference, the rotation speed of the permanent magnet can be controlled by controlling the magnitude of the current under different pressure differences, that is, when the pressure difference increases, the current is controlled to increase, so as to realize the vibration of the cleaning drum 121 with different intensities and achieve different cleaning function modes. This adaptive cleaning mode not only improves the user experience but also demonstrates the high intelligent level of modern cleaning technology.

[0076] In one embodiment, the rotation axis of the permanent magnet 15 is coaxial with the central axis of the cleaning roller 121 .

[0077] In this embodiment, the coaxial design helps to improve the stability of the permanent magnet 15 during rotation, reduce mechanical wear, and make the cleaning roller 121 more stable and reliable during operation.

[0078] An embodiment of the present invention further provides an air conditioner outdoor unit, comprising the cleaning device as described above.

[0079] See also Figure 8 The embodiment of the present invention further provides a cleaning control method, which is applied to the air conditioner outdoor unit as described above, comprising:

[0080] S801, detecting the pressure difference between the inside and outside of the condenser 3 by means of a pressure detection component;

[0081] S802 , when the pressure difference reaches a preset threshold, the driving member is controlled to drive the cleaning roller 121 to move and clean the outer surface of the condenser 3 , and the vibration component is controlled to start the vibration function.

[0082] In this embodiment, the pressure difference between the inside and outside of the condenser 3 is regularly collected through the pressure detection component. When the pressure difference does not reach the preset threshold, it means that the amount of dust is small and does not affect the heat dissipation, and no cleaning is required; when the pressure difference reaches the preset threshold, it means that the amount of dust has reached the level that affects the heat dissipation and needs to be cleaned. During the cleaning process, the cleaning component 12 and the vibration component can be enabled at the same time, so that the cleaning component 12 adds a vibration effect when moving and cleaning, thereby enhancing the cleaning force, effectively dealing with the situation where the dust is too thick, improving the cleaning effect, and then ensuring the heat dissipation capacity of the condenser 3.

[0083] See also Figure 9 In one embodiment, step S802 includes:

[0084] S901, when the pressure difference reaches a preset threshold, the driving member is controlled to drive the cleaning roller 121 to move and clean the outer surface of the condenser 3;

[0085] S902: Control the vibration component to generate a vibration action of a corresponding intensity according to the corresponding pressure difference value, wherein the greater the pressure difference value, the greater the intensity of the vibration action.

[0086] In this embodiment, in order to better clean the condenser 3 under different conditions, a detection and control function is designed to intelligently clean the condenser 3 under different conditions (ie, conditions with different dust amounts).

[0087] Preferably, three different cleaning modes with different intensities can be set. When the detected pressure difference △P < 0.5 kp (i.e., the preset threshold is not reached), the condenser 3 is relatively clean and no cleaning is performed; when 0.5 kp ≤ △P < 1.0 kp, the cleaning condition is reached and the condenser 3 is slightly blocked. The first current value is controlled to be passed through the energized coil 17 to control the permanent magnet to vibrate slightly to perform a mild cleaning mode; when 1.0 kp ≤ △P < 1.5 kp, the condenser 3 is moderately blocked. The second current value (i.e., greater than the first current value) is controlled to be passed through the energized coil 17 to control the permanent magnet to vibrate moderately to perform a medium cleaning mode; when △P ≥ 1.5 kp, the condenser 3 is severely blocked. The third current value (i.e., greater than the second current value) is controlled to be passed through the energized coil 17 to control the permanent magnet to vibrate severely to perform a heavy cleaning mode. During the whole cleaning process, different cleaning modes are continuously switched according to the pressure difference until the cleaning stops after △P < 0.5 kp.

[0088] It should be noted that the number of gears of the cleaning mode is not fixed at three, and can be flexibly set according to actual needs. For example, it can be set to four, five or more different cleaning intensity modes to adapt to different degrees of blockage of the condenser 3. At the same time, the preset threshold can also be adjusted according to the actual operating conditions and use environment of the condenser 3 to ensure the optimization of the cleaning effect. In addition, during the cleaning process, other sensor data, such as temperature, humidity, etc., can be combined to more finely control the cleaning mode, further improving the cleaning efficiency and operating stability of the condenser 3.

[0089] In summary, it is easy for those skilled in the art to understand that, on the premise of no conflict, the above-mentioned advantageous technical features can be freely combined and superimposed.

[0090] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
