Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a control method for cleaning an air conditioner and an air conditioner. Background Art

[0002] The coil fins of the air conditioner are prone to adhesion and accumulation of dust. When the amount of accumulated dust is large, it is easy to cause blockage, resulting in a decrease in the heat exchange capacity of the coil and an increase in the heat exchange airflow resistance, which in turn leads to an increase in the power consumption of the air conditioner and an increase in the failure rate. In the prior art, the coil is usually cleaned and dusted by water washing after the air conditioner is shut down. On the one hand, when the temperature is low, after the coil is washed with water, the water is easy to freeze on the surface of the coil, which is not conducive to restarting the air conditioner. On the other hand, when the air conditioner is heating, a large amount of condensed water is usually not generated.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0064] Figure 1 FIG. 1 is a schematic flow chart of a control method for air conditioning cleaning according to an embodiment of the present invention. Figure 1 As shown, combined with Figure 2-13 The present invention provides a control method for cleaning an air conditioner, wherein the air conditioner comprises a coil 1 and a cleaning system 2, wherein the cleaning system 2 comprises a dust collecting device 7. The control method comprises:

[0065] S1 obtains the dust accumulation form on the surface of the coil 1, and the dust accumulation form includes dry dust accumulation and wet dust accumulation;

[0066] S2 performs a cleaning operation.

[0067] Among them, cleaning operations include:

[0068] In response to the dust accumulation being dry dust, the dust collecting device 7 is controlled to remove the dust accumulated on the surface of the coil 1 in step S21.

[0069] In the present application, the air conditioner may be a combined air conditioner or an air handling unit, etc. A dust collecting device 7 is provided in the cleaning system 2 of the air conditioner. When it is determined that the dust accumulation on the surface of the air conditioning coil 1 is in the form of dry dust accumulation, it means that the coil 1 may have been operating in a heating mode, or an air supply mode, a ventilation mode, etc., and the coil 1 did not produce condensed water. Dust is usually attached to the surface of the coil 1 by electrostatic force and is relatively easy to remove. At this time, the dust accumulated on the surface of the coil 1 can be directly removed by the dust collecting device 7. Since the water washing cleaning in the prior art is not adopted, on the one hand, water will not adhere to the surface of the coil 1, thereby causing ice to form. On the other hand, there is no need to access a water source, which leads to a complex structure.

[0070] In some embodiments of the control method of the present application, Figure 2 As shown, the method of obtaining the dust accumulation form on the surface of the coil 1 includes:

[0071] S111 obtains the most recent operating condition of coil 1, where the operating condition includes a condition with condensed water and a condition without condensed water;

[0072] S112, in response to the operating condition being a condition without condensed water, determining that the dust accumulation form is dry dust accumulation;

[0073] In response to the operating condition being a condensed water condition, S113 determines that the dust accumulation form is wet dust accumulation.

[0074] In this embodiment, the dust accumulation form on the surface of the coil 1 is determined by obtaining the most recent operating condition of the coil 1. When the air conditioner is running, the coil 1 is usually not cleaned, otherwise dust may enter the indoor space with the temperature-controlled airflow. Generally speaking, the time to clean the coil 1 is when the air conditioner is shut down and the coil 1 stops working. Of course, it can also be when the air conditioner temperature reaches a preset value and the coil 1 is temporarily dormant. The most recent operating condition of the coil 1 is the operating condition before the coil 1 stops working or temporarily dormant.

[0075] In this embodiment, the working condition without condensation water may include heating, blowing, ventilation, etc. In this working condition, the coil 1 will not generate condensation water, which can be determined as dry dust accumulation. At this time, the dust will not solidify on the surface of the coil 1 through moisture. The dust usually adheres to the surface of the coil 1 through electrostatic force and is easier to remove. The working condition with condensation water may include cooling, humidification, etc. In this working condition, the coil 1 may generate condensation water, and the dust may solidify on the surface of the coil 1 through moisture, which can be determined as wet dust accumulation. Wet dust is more difficult to remove by suction.

[0076] In some embodiments of the control method of the present application, Figure 8 As shown, the cleaning system 2 also includes a humidity detection device. The method of obtaining the dust accumulation form on the surface of the coil 1 includes:

[0077] S121 detects the humidity of the surface of the coil 1 through a humidity detection device;

[0078] S122: in response to the humidity condition being dry, determining that the dust accumulation form is dry dust accumulation;

[0079] In response to the humidity condition being damp, S123 determines that the dust accumulation form is wet dust accumulation.

[0080] In this embodiment, the humidity detection device may include a humidity sensor, etc., which can detect the humidity on the surface of the coil 1. When the surface of the coil 1 is dry, the dust accumulation form is determined to be dry dust accumulation. When the surface of the coil 1 is wet, the dust accumulation form is determined to be wet dust accumulation.

[0081] It should be understood that this embodiment can be implemented together with the previous embodiment to improve the accuracy of determining the form of dust accumulation.

[0082] In some embodiments of the control method of the present application, Fig. 9 As shown, the cleaning system 2 further includes a first moving device 8a, which is configured to drive the dust collecting device 7 to move in a first plane, and the first plane is close to and parallel to the surface of the coil 1. The control of the dust collecting device 7 to remove dust accumulated on the surface of the coil 1 includes:

[0083] S211 controls to start the dust collecting device 7; and

[0084] S212 controls the first moving device 8a to drive the dust collecting device 7 to scan and move along the first plane.

[0085] The coil 1 is usually of small thickness and is arranged perpendicular to the heat exchange air duct. In this embodiment, the first plane may be a plane parallel to the coil 1, the first plane is perpendicular to the heat exchange air duct, and is located upstream or downstream of the coil 1. Preferably, the first plane is located upstream of the coil 1. For the dust collection device 7, the closer to the surface of the coil 1, the higher the dust collection efficiency, therefore, the first plane may be as close to the surface of the coil 1 as possible. The first moving device 8a may have a telescopic structure, so that it can be retracted when the coil 1 is working normally to avoid blocking or affecting the heat exchange airflow; it can be extended when cleaning the coil 1, and drive the dust collection device 7 to scan and move within the first plane to remove dust from every area of ​​the surface of the coil 1 as much as possible.

[0086] In some embodiments of the control method of the present application, Figure 5As shown, the dust collecting device 7 may include a dust collecting chamber 71, a motor compartment 72, a sewage pipe 73, a suction nozzle 74 and a suction pipe 75. The suction nozzle 74 is arranged toward the coil 1. The dust collecting device 7 as a whole or at least the suction nozzle 74 can be driven by the first moving device 8a to scan and move along the first plane.

[0087] In some embodiments of the control method of the present application, Figure 7 As shown, the first moving device 8a may include a moving device base 81, a transverse sliding beam 82 and a longitudinal sliding beam 83, and the dust collecting device 7 is slidably arranged at one end of the transverse sliding beam 82 or the longitudinal sliding beam 83. The transverse sliding beam 82 and the longitudinal sliding beam 83 form a plane, which is parallel to the first plane and the plane of the surface of the coil 1. The dust collecting device 7 performs transverse scanning movement along the transverse sliding beam 82 and performs longitudinal scanning movement along the longitudinal sliding beam 83. Through the transverse scanning movement and the longitudinal scanning movement, the dust collecting device 7 can remove the dust accumulated in each area of ​​the surface of the coil 1.

[0088] In some embodiments of the control method of the present application, the cleaning system 2 further includes a water washing device 9. The cleaning operation further includes:

[0089] In response to the dust accumulation being in the form of wet dust accumulation, the water washing device 9 is controlled to clean the dust accumulation on the surface of the coil 1.

[0090] In this embodiment, a water washing device 9 is provided in the cleaning system 2 of the air conditioner. When it is determined that the dust accumulation on the surface of the air conditioner coil 1 is wet dust accumulation, it means that the coil 1 may have been running in a cooling mode or a humidification mode, and the coil 1 has generated condensed water. Dust is usually firmly attached to the surface of the coil 1 by moisture, and is not easily removed by the dust collecting device 7. At this time, the dust accumulation on the surface of the coil 1 can be removed by water washing through the water washing device 9. The water washing device 9 can spray moisture toward the surface of the coil 1 to remove the dust accumulation.

[0091] In this embodiment, the water washing device 9 can use condensed water for water washing, and can also be connected to an additional water source through a pipeline, and can be set up according to needs.

[0092] In some embodiments of the control method of the present application, Figure 6 and Fig.10 As shown, the water washing device 9 includes a water spray device 91 and a brush 92. The cleaning system 2 also includes a second moving device 8b, which is configured to drive the water washing device 9 to move in a second plane, and the second plane is close to and parallel to the surface of the coil 1. The control of the water washing device 9 to remove dust accumulated on the surface of the coil 1 includes:

[0093] S221 controls the water washing device 9 to start; and

[0094] S222 controls the second moving device 8b to drive the water washing device 9 to scan and move along the second plane.

[0095] In this embodiment, the second plane may be a plane parallel to the coil 1, the second plane is perpendicular to the heat exchange air duct, and is located upstream or downstream of the coil 1. Preferably, the second plane is located upstream of the coil 1. The second moving device 8b may have a telescopic structure, so that it can be retracted when the coil 1 is working normally to avoid blocking or affecting the heat exchange airflow; it can be extended when cleaning the coil 1, and drive the dust collecting device 7 to scan and move in the second plane to remove dust from every area on the surface of the coil 1 as much as possible.

[0096] In this embodiment, in order to thoroughly remove the dust firmly accumulated on the surface of the coil 1, a water spray device 91 and a brush 92 are provided. The water spray device 91 is spaced apart from the coil 1 and is used to spray water toward the surface of the coil 1. The brush 92 is provided in contact with the surface of the coil 1 and is used to remove the dust firmly accumulated on the surface of the coil 1. The brush 92 can brush each area of ​​the surface of the coil 1 when moving with the second moving device 8b.

[0097] In some embodiments of the control method of the present application, the second plane may be coplanar with the first plane.

[0098] In some embodiments of the control method of the present application, the second moving device 8b may be the same device as the first moving device 8a. That is, the dust collecting device 7 and the water washing device 9 are both arranged on the first moving device 8a, and the dust collecting device 7 and the water washing device 9 are arranged adjacently or at intervals.

[0099] In some embodiments of the control method of the present application, Figure 6 As shown, the water washing device 9 may include a water spraying device 91, a brush 92, a water chamber 93 and a water pump chamber 94. The water spraying device 91 is arranged toward the coil 1. The dust collecting device 7 as a whole or at least the water spraying device 91 and the brush 92 may be driven by the second moving device 8b to scan and move along the second plane.

[0100] In some embodiments of the control method of the present application, Figure 7 As shown, the second moving device 8b may include a moving device base 81, a transverse sliding beam 82 and a longitudinal sliding beam 83, and the dust collecting device 7 is slidably arranged at one end of the transverse sliding beam 82 or the longitudinal sliding beam 83. The transverse sliding beam 82 and the longitudinal sliding beam 83 form a plane, which is parallel to the second plane and the plane of the surface of the coil 1. The water washing device 9 realizes transverse scanning movement along the transverse sliding beam 82 and realizes longitudinal scanning movement along the longitudinal sliding beam 83. Through the transverse scanning movement and the longitudinal scanning movement, the dust accumulated in each area of ​​the surface of the coil 1 can be removed.

[0101] In some embodiments of the control method of the present application, Figure 6 and Fig.11 As shown, the dust collecting device 7 further includes a dust collecting chamber 71, a water spray pipe (not shown) connected to the dust collecting chamber 71, and a sewage discharge pipe 73 connected to the dust collecting chamber 71. After the dust collecting device 7 is controlled to remove dust accumulated on the surface of the coil 1, the control method further includes:

[0102] S31 flushes the dust collecting chamber 71 through a water spray pipe; and

[0103] S32 discharges sewage through the sewage pipe 73.

[0104] In this embodiment, the dust collecting device 7 can automatically clean the dust collecting chamber 71 to prevent the dust collecting chamber 71 from being full of dust, thereby saving trouble and effort and requiring no manual maintenance.

[0105] In some embodiments of the control method of the present application, Figure 4 As shown, the air conditioner further comprises a water baffle 5, which is movably arranged on a side of the coil 1 away from the water washing device 9. Before the water washing device 9 is controlled to remove dust accumulated on the surface of the coil 1, the cleaning operation further comprises:

[0106] S41 controls the water baffle plate 5 to at least partially block the side of the coil 1 away from the water washing device 9 .

[0107] In this embodiment, the water washing device 9 can be arranged upstream of the coil 1, and the water baffle 5 can be arranged downstream of the coil 1. When the coil 1 is working normally, the water baffle 5 opens the heat exchange air duct to avoid blocking and affecting the heat exchange air flow. When cleaning the coil 1, the water baffle 5 completely or partially blocks the heat exchange air duct to prevent moisture, dust, etc. from entering the heat exchange air duct during the cleaning process, polluting the inner wall of the air duct, and even entering the indoor space.

[0108] In some embodiments of the control method of the present application, Fig.12 As shown, before obtaining the dust accumulation form on the surface of the coil 1, the control method further includes:

[0109] S51 obtains a cleaning mode of the air conditioner, where the cleaning mode includes an automatic cleaning mode and a manual cleaning mode;

[0111] S53 responds to the cleaning mode being the manual cleaning mode, and starts to execute the above-mentioned acquisition of the dust accumulation form on the surface of the coil 1 when the coil 1 stops running.

[0112] In this embodiment, the air conditioner is provided with an automatic cleaning mode, which can automatically clean the coil 1, saving trouble and labor, and requiring no manual maintenance. Specifically, the cleaning can be automatically performed after a preset time interval, for example, 1 hour after the coil 1 stops running. Exemplarily, the air conditioner is shut down at the user's off-duty time, for example, at 6 pm. If cleaning is performed at this time, noise may be generated, affecting people who are still stranded indoors. The time for performing cleaning can be set to 1 hour or 2 hours after shutdown. At this time, the probability of people still stranded in the room is low, and the cleaning will not affect the people.

[0113] In this embodiment, the air conditioner is also provided with a manual cleaning mode. When the user thinks that the coil 1 needs to be cleaned, the user can input relevant instructions. When the coil 1 stops running or when the air conditioner is temporarily dormant, the cleaning is performed. Of course, the user can also input instructions to control the coil 1 to stop running immediately and perform cleaning. Alternatively, the user can also input instructions to control the coil 1 to perform cleaning after a preset time interval after it stops running.

[0114] In some embodiments of the control method of the present application, before obtaining the dust accumulation form on the surface of the coil 1, the control method further includes: in response to the cleaning mode being an automatic cleaning mode, starting to execute the obtaining the dust accumulation form on the surface of the coil 1 at a preset time and when the coil 1 stops running.

[0115] In this embodiment, the automatic cleaning mode can also be set to a fixed preset time every day, for example, 12 o'clock in the evening. At this time, if the coil 1 is in a stopped state, cleaning will automatically start. It saves worry and labor, does not require manual maintenance, and will not affect the user.

[0116] In some embodiments of the control method of the present application, Figure 3 As shown, the control method includes:

[0117] S91 determines whether the air conditioner cleaning mode is the automatic cleaning mode, is at the preset time at night, and the coil 1 stops running; or

[0118] S92 determines whether the air conditioner cleaning mode is the manual cleaning mode and the coil 1 stops running;
