Referring to FIG. 1 , FIG. 1 shows a schematic diagram of the structure of a cleaning device for an air-conditioning unit in an embodiment of the present invention. The cleaning device provided in an embodiment of the present invention includes an instruction acquisition module 110, a control module 120, a drive module 130, a transmission module 140 and a cleaning module 150 as shown in FIG. 3 ; the instruction acquisition module 110 is used to acquire and send a cleaning instruction to the control module 120; the control module 120 is used to drive the drive module 130 to drive the cleaning module 150 to move through the transmission module 140 when receiving a cleaning instruction, so as to clean the filter 210 and/or the surface cooler 220 of the air-conditioning unit.

Wherein, referring to Figures 1 to 3, the air conditioning unit includes: a shell 230, a filter 210 and a cooler 220; the shell 230 has an air outlet, the filter 210 is arranged at the air outlet, and the cooler 220 is arranged in the shell 230 and corresponds to the air outlet. As an example, the cleaning module 150 of the cleaning device is used to wash the filter 210 and the cooler 220. It should be noted that the cleaning module 150 uses a cleaning agent (such as water) to clean the filter 210 and/or the cooler 220, and brushes away the dust on the filter 210 and/or the cooler 220 through its own movement, wherein the cleaning process and the brushing process can be carried out simultaneously, or the brushing can be carried out first and then the cleaning.

As an example, the control module 120 is a PLC (Programmable Logic Controller). The control module 120 may be the same control module 120 as the control module 120 of the air conditioning unit.

As described above, in the cleaning device for the air-conditioning unit, the instruction acquisition module 110 acquires and sends a cleaning instruction to the control module 120. When the control module 120 receives the cleaning instruction, it drives the drive module 130 to drive the transmission module 140 to move, and then drives the cleaning module 150 to move, so as to realize the cleaning of the filter 210 and/or the cooler 220 of the air-conditioning unit. It can be seen that the cleaning device can automatically clean the filter 210 and/or the cooler 220 of the air-conditioning unit, avoiding the need to remove the filter 210 and/or the cooler 220 from the air-conditioning unit before cleaning, and there is no need to manually clean the filter 210 and/or the cooler 220, which can reduce labor intensity and provide user experience.

Regarding how the instruction acquisition module 110 acquires the cleaning instruction, the embodiment of the present invention provides two examples.

Example (1): The instruction acquisition module 110 includes a timing switch, which is used to generate and send a cleaning instruction to the control module 120 when the air conditioning unit runs for a preset time. It should be noted that when the cleaning of the air conditioning unit is completed this time, the timing switch is reset to zero and the timing is restarted. As an example, the timing switch can count the running time of the fan of the air conditioning unit, and when the running time reaches the preset time, it generates and sends a cleaning instruction to the control module 120.

Example (2): The instruction acquisition module 110 includes a pressure difference switch, which is used to generate and send a cleaning instruction to the control module 120 when the internal and external pressure difference of the air-conditioning unit reaches a preset pressure difference. It can be understood that the internal and external pressure difference of the air-conditioning unit refers to the pressure difference between the internal environment of the air-conditioning unit near the filter 210 and the external environment of the air-conditioning unit near the filter 210. Among them, the size of the preset pressure difference can be set according to the actual working conditions. For example, it can be set to 0.1MPa, 0.5MPa, 1MPa, etc. Compared with the example (1), the method provided by this example can avoid interference from the external environment (for example, when the air quality of the air-conditioning unit is poor, the filter 210 and/or the surface cooler 220 of the air-conditioning unit need to be cleaned before the air-conditioning unit has not been running for a preset time), and the filter 210 and/or the surface cooler 220 of the air-conditioning unit can be cleaned in time to ensure the normal operation of the air-conditioning unit.

In some embodiments of the present invention, the driving module 130 can drive the transmission module 140 to drive the cleaning module 150 to move in a first direction and a second direction, wherein the first direction is opposite to the second direction; the control module 120 is used to drive the driving module 130 to drive the cleaning module 150 to move in the first direction for a first preset time and in the second direction for a second preset time through the transmission module 140. In this way, the cleaning module 150 can enhance the dust removal effect on the filter 210 and/or the cooler 220.

Optionally, the first preset time length and the second preset time length are both equal to the length of the filter 210 or/and the cooler 220 along the first direction divided by the movement speed of the cleaning module 150. The number of movement rounds of the cleaning module 150 can be determined according to the degree of dirtiness of the filter 210 or/and the cooler 220, or the internal and external pressure difference of the air-conditioning unit, or the operating time of the air-conditioning unit, wherein one movement round refers to movement from one end of the filter 210 or/and the cooler 220 to the other end along the first direction and movement from one end of the filter 210 or/and the cooler 220 to the other end along the second direction.

Of course, in some other embodiments of the present invention, the first preset time length and the second preset time length may also be less than the length of the filter 210 and/or the cooler 220 along the first direction divided by the movement speed of the cleaning module 150. The embodiment of the present invention does not limit the specific movement path of the cleaning module 150, as long as the cleaning area of the filter 210 and/or the cooler 220 is fully covered.

Furthermore, in some embodiments of the present invention, the control module 120 is also used to drive the driving module 130 to reset the cleaning module 150 through the transmission module 140 after the cleaning module 150 is cleaned. In this way, it is convenient for the cleaning module 150 to clean the filter 210 and/or the cooler 220 next time.

In some embodiments of the present invention, as shown in FIG. 1 and FIG. 2 , the drive module 130 includes a motor. Such a drive module 130 structure. The drive module 130 can be installed in the housing 230 of the air conditioning unit through the mounting bracket 160 shown in FIG. 2 . Of course, in some other embodiments of the present invention, the drive module 130 can be a structure in which a hydraulic cylinder (or pneumatic cylinder) and a connecting rod are combined. The connecting rod can convert linear motion into rotational motion, and the connecting rod has a rotatable output end, which is connected to the transmission module 140.

In some embodiments of the present invention, as shown in Figures 1 to 3, the driving module 130 has a rotatable output end, and the transmission module 140 includes: a driving wheel 141, a first driven wheel 142, a second driven wheel 143, a third driven wheel 144, a conveyor belt 145 and a first rotating shaft 146 and a second rotating shaft 147 that are all rotatable; the driving wheel 141 is arranged on the output end of the driving module 130 and meshes with the first driven wheel 142; the first driven wheel 142 and the second driven wheel 143 are fixedly connected to the first rotating shaft 146, and the third driven wheel 144 is fixedly connected to the second rotating shaft 147; the conveyor belt 145 is tensioned on the second driven wheel 143 and the third driven wheel 144 and connected to the cleaning module 150. The output end of the driving module 130 drives the driving wheel 141 to rotate, and the first driven wheel 142 rotates under the engagement of the driving wheel 141, and at the same time drives the second driven wheel 143 to rotate, so that the conveyor belt 145 moves around the second driven wheel 143 and the third driven wheel 144, and the cleaning module 150 moves under the action of the conveyor belt 145.

Optionally, the first rotating shaft 146 and the second rotating shaft 147 can be rotatably disposed in the housing 230 of the air conditioning unit through the support bracket 170 shown in FIG2 . It is understandable that an axial hole is disposed on the support bracket 170. A bearing can be installed in the axial hole, and the first rotating shaft 146 or the second rotating shaft 147 is passed through the inner ring of the corresponding bearing.

Optionally, as shown in FIG. 4 and FIG. 5 , a connecting rack 151 is provided on the cleaning module 150, and the connecting rack 151 is meshed with the conveyor belt 145. In this way, it is convenient to disassemble and assemble the cleaning module 150. Specifically, the conveyor belt 145 can be a chain conveyor belt. The connecting rack 151 can be meshed with the upper belt plane or the lower belt plane of the conveyor belt 145 according to actual needs, so as to facilitate the installation of the cleaning module 150.

As shown in FIG3 , the air conditioning unit is provided with a first guide portion 231 and a second guide portion 232 which are spaced apart from each other, the first end of the cleaning module 150 moves along the first guide portion 231, and the second end moves along the second guide portion 232, wherein the first end and the second end of the cleaning module 150 are relatively distributed. By limiting the first guide portion 231 and the second guide portion 232, the cleaning module 150 can be prevented from falling off the conveyor belt 145 during the movement. The first guide portion 231 and the second guide portion 232 are both provided with guide grooves, and the first end and the second end of the cleaning module 150 extend into the guide grooves on the first guide portion 231 and the second guide portion 232, respectively. Referring to FIG3 , the first guide portion 231 and the second guide portion 232 can be provided on the outer wall of the housing 230 of the air conditioning unit to guide the cleaning module 150 used for washing the filter 210. The first guide portion 231 and the second guide portion 232 may also be disposed on a wall of the condenser 220 away from the filter 210 to guide the cleaning module 150 for cleaning the condenser 220 .

Further, as shown in FIG. 1 and FIG. 2 , the number of the second driven wheel 143, the third driven wheel 144, the conveyor belt 145 and the cleaning module 150 are all two; the second driven wheel 143 is spaced apart along the axial direction of the first rotating shaft 146, and the third driven wheel 144 is spaced apart along the axial direction of the second rotating shaft 147; the conveyor belt 145 is stretched on the corresponding second driven wheel 143 and the corresponding third driven wheel 144 and connected to the corresponding cleaning module 150. In this way, a common driving module 130 can be used to drive the two cleaning modules 150 to operate at the same time, so as to realize the cleaning of the filter 210 and the surface cooler 220, which can reduce the processing cost and cleaning cost of the cleaning device. It can be understood that one of the second driven wheels 143, one third driven wheel 144, one conveyor belt 145 and one cleaning module 150 are distributed near the cooler 220 as shown in Figure 2, and another second driven wheel 143, another third driven wheel 144, another conveyor belt 145 and another cleaning module 150 are distributed near the filter 210 as shown in Figure 3.

Of course, in some other embodiments of the present invention, the number of the driving modules 130 and the transmission modules 140 are both two, and one driving module 130 drives one cleaning module 150 to move through one transmission module 140. The transmission module 140 may include a lead screw connected to the rotatable output end of the driving module 130 and a lead screw nut sleeved on the lead screw, and the lead screw nut is connected to the corresponding cleaning module 150. The transmission module 140 of this type of structure is simple in structure, but the use of two driving modules 130 will increase the cleaning cost.

As shown in Figure 5, in some embodiments of the present invention, the water inlet pipe 152 has a plurality of water outlet holes on its side wall, and the water inlet pipe 152 is connected to the transmission module 140; the cleaning brush 153 is arranged on the water inlet pipe 152 and distributed around the water outlet holes.

Optionally, as shown in FIG5 , the cleaning brush 153 includes: a base 1531 and bristles 1532 arranged on the wall of the base 1531 away from the water inlet pipe 152. The base 1531 is provided with an opening opposite to the water outlet. As shown in FIG5 , the water inlet pipe 152 is fixed to the base 1531 of the cleaning brush 153 by a clamp. As shown in FIG5 , the connecting rack 151 is arranged on the base 1531 of the cleaning brush 153.

Optionally, one end of the water inlet pipe 152 is closed, and the other end is connected to the control valve 240 of the air conditioning unit. The control valve 240 is electrically connected to the control module 120. The control module 120 is used to control the control valve 240 to close the water passage between the cooler 220 and the water pipe and to open the water passage between the cleaning module 150 and the water pipe when receiving a cleaning instruction. In this way, it is convenient to clean the cooler 220 and/or the filter 210.

It is understandable that when the air conditioning unit is running, the control module 120 controls the control valve 240 to open the water passage between the surface cooler 220 and the water pipe and close the water passage between the cleaning module 150 and the water pipe. It should be noted that the control module 120 is used to open the drive module 130 when receiving the cleaning instruction and close the drive module 130 when the air conditioning unit is running. Among them, the control valve 240 can be a three-way structure.

An embodiment of the present invention provides an air conditioning system, which includes: an air conditioning unit and any one of the cleaning devices described above; the cleaning module 150 of the cleaning device is used to clean the filter 210 and/or the surface cooler 220 of the air conditioning unit.

In the air-conditioning system described above, the instruction acquisition module 110 of the cleaning device acquires and sends a cleaning instruction to the control module 120. When the control module 120 receives the cleaning instruction, it drives the driving module 130 to drive the transmission module 140 to move, and then drives the cleaning module 150 to move, so as to realize the cleaning of the filter 210 and/or the cooler 220 of the air-conditioning unit. It can be seen that the cleaning device can automatically clean the filter 210 and/or the cooler 220 of the air-conditioning unit, avoiding the need to remove the filter 210 and/or the cooler 220 from the air-conditioning unit before cleaning, and there is no need to manually clean the filter 210 and/or the cooler 220, which can reduce labor intensity and provide user experience.

In some embodiments of the present invention, as shown in FIG3 , the air conditioning unit is provided with a first guide portion 231 and a second guide portion 232 that are spaced apart; the first end of the cleaning module 150 moves along the first guide portion 231, and the second end moves along the second guide portion 232, wherein the first end and the second end of the cleaning module 150 are relatively distributed. By limiting the first guide portion 231 and the second guide portion 232, the cleaning module 150 can be prevented from falling off the conveyor belt 145 during the movement. The first guide portion 231 and the second guide portion 232 are both provided with guide grooves, and the first end and the second end of the cleaning module 150 extend into the guide grooves on the first guide portion 231 and the second guide portion 232, respectively. Referring to FIG3 , the first guide portion 231 and the second guide portion 232 can be provided on the outer wall of the housing 230 of the air conditioning unit to guide the cleaning module 150 used to wash the filter 210. The first guide portion 231 and the second guide portion 232 may also be disposed on a wall of the condenser 220 away from the filter 210 to guide the cleaning module 150 for cleaning the condenser 220 .

In some embodiments of the present invention, as shown in FIG1 , a control valve 240 is provided on the air-conditioning unit; the control module 120 is used to control the control valve 240 to close the water passage between the surface cooler 220 and the water pipe and to open the water passage between the cleaning module 150 and the water pipe when receiving a cleaning instruction. It is understandable that when the air-conditioning unit is running, the control module 120 controls the control valve 240 to open the water passage between the surface cooler 220 and the water pipe and to close the water passage between the cleaning module 150 and the water pipe. It should be noted that the control module 120 is used to open the drive module 130 when receiving a cleaning instruction and to close the drive module 130 when the air-conditioning unit is running. Among them, the control valve 240 can be a three-way structure.

Another embodiment of the present invention further provides a method for cleaning an air conditioning unit, the cleaning method comprising:

Step S100, obtaining and sending a cleaning instruction;

Step S200: Based on the cleaning instruction, the driving module 130 of the cleaning device drives the cleaning module 150 of the cleaning device to move through the transmission module 140 of the cleaning device to clean the filter 210 and/or the surface cooler 220 of the air-conditioning unit.

The cleaning method of the air-conditioning unit as described above can automatically clean the filter 210 and/or the surface cooler 220 of the air-conditioning unit, avoiding the need to remove the filter 210 and/or the surface cooler 220 from the air-conditioning unit before cleaning, and also eliminating the need for manual cleaning of the filter 210 and/or the surface cooler 220, thereby reducing labor intensity and improving user experience.

In some embodiments of the present invention, step S100 may include: generating and sending a cleaning instruction when the internal and external pressure difference of the air-conditioning unit reaches a preset pressure difference. It is understandable that the internal and external pressure difference of the air-conditioning unit refers to the pressure difference between the internal environment of the air-conditioning unit near the filter 210 and the external environment of the air-conditioning unit near the filter 210. Among them, the size of the preset pressure difference can be set according to the actual working conditions. For example, it can be set to 0.1MPa, 0.5MPa, 1MPa, etc. In this way, interference from the external environment can be avoided (for example, when the air quality of the air-conditioning unit is poor, the filter 210 or/and the cooler 220 of the air-conditioning unit needs to be cleaned before the air-conditioning unit has not run for a preset time), and the filter 210 or/and the cooler 220 of the air-conditioning unit can be cleaned in time to ensure the normal operation of the air-conditioning unit.

In some embodiments of the present invention, step S200 may include: driving the driving module 130 to drive the cleaning module 150 to move along the first direction for a first preset time and along the second direction for a second preset time through the transmission module 140, wherein the first direction is opposite to the second direction. In this way, the cleaning module 150 can enhance the dust removal effect on the filter 210 and/or the surface cooler 220.

Optionally, the first preset time length and the second preset time length are both equal to the length of the filter 210 or/and the cooler 220 along the first direction divided by the movement speed of the cleaning module 150. The number of movement rounds of the cleaning module 150 can be determined according to the degree of dirtiness of the filter 210 or/and the cooler 220, or the internal and external pressure difference of the air-conditioning unit, or the operating time of the air-conditioning unit, wherein one movement round refers to movement from one end of the filter 210 or/and the cooler 220 to the other end along the first direction and movement from one end of the filter 210 or/and the cooler 220 to the other end along the second direction.

Of course, in some other embodiments of the present invention, the first preset time length and the second preset time length may also be less than the length of the filter 210 and/or the cooler 220 along the first direction divided by the movement speed of the cleaning module 150. The embodiment of the present invention does not limit the specific movement path of the cleaning module 150, as long as the cleaning area of the filter 210 and/or the cooler 220 is fully covered.

Furthermore, in some embodiments of the present invention, the cleaning method further includes: step S300, driving the driving module 130 to reset the cleaning module 150 through the transmission module 140. In this way, it is convenient for the cleaning module 150 to clean the filter 210 and/or the cooler 220 next time.

In some embodiments of the present invention, as shown in FIG1 , a control valve 240 is provided on the air conditioning unit; before the driving module 130 drives the cleaning module 150 to move through the transmission module 140, the cleaning method further includes: step 400, when a cleaning instruction is received, the control valve 240 is controlled to close the water passage between the cooler 220 and the water pipe and to open the water passage between the cleaning module 150 and the water pipe. In this way, it is convenient to clean the cooler 220 and/or the filter 210.

Another embodiment of the present invention provides a computer-readable storage medium having a computer program stored thereon, and when the computer program is executed by a processor, the steps of any one of the cleaning methods described above are implemented.
