Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, specifically to an automatic dust removal system for an electrical control box, an air conditioner, and a dust removal control method. Background Technology

[0002] Rooftop air conditioners are typically placed outdoors or on rooftops, where dust levels are higher than indoors. Although existing control boxes use a sealed structure, there are still areas that allow dust to enter, such as door gaps and wiring inlets. Over time, this dust accumulation can lead to a thick layer of dust covering the inside of the control box and the casings of all components. This can easily increase the level of contamination, reduce electrical clearances and creepage distances, and even damage the unit. In more serious cases, it can cause safety issues such as component burnout.

[0003] To prevent the above situation from occurring, it is necessary to clean the outdoor electrical control box regularly. This requires personnel to regularly inspect and maintain it, thus increasing labor costs.

[0004] Therefore, existing technologies need further development. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide an automatic dust removal system for an electrical control box, an air conditioner, and a dust removal control method to solve the technical problem that automatic dust removal cannot be performed inside the electrical control box in related technologies.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: An automatic dust removal system for an electrical control box is provided, comprising: an electrical control box, the bottom of which is provided with a dust discharge port and a light sensor; the dust discharge port is used to discharge dust from inside the electrical control box, and the light sensor is used to detect the thickness of the dust; a dust collection component, one end of which is connected to the dust discharge port, and the other end of which is provided with an air valve and a first actuator; the dust collection component is used to collect and transport dust discharged from the dust discharge port; the first actuator controls the opening and closing of the air valve; a filter assembly, connected to the dust collection component, and containing an electrostatic dust removal device; and an air supply assembly, which is connected to the filter assembly. The components are connected, and the air supply component is equipped with a dust removal port, a fan, and a second actuator. The second actuator controls the opening and closing of the dust removal port. The control module is connected to the light sensor, the first actuator, the electrostatic precipitator, the fan, and the second actuator. When the light sensor detects that the dust thickness at the bottom of the electrical control box is greater than the preset value N, the light sensor transmits a signal to the control module. The control module starts the first actuator and the second actuator to open the air valve and the dust removal port respectively. At the same time, it starts the fan and the electrostatic precipitator. The electrical control box generates negative pressure, which draws the dust inside the electrical control box through the dust collection component to the electrostatic precipitator for ionization, and then discharges it from the dust removal port.

[0007] Furthermore, the dust collection component also includes an air duct that connects to the dust outlet; and an air valve that is located between the air duct and the filter assembly.

[0008] Furthermore, a bracket is provided on the filter assembly, and the electrostatic dust removal device is fixed on the bracket.

[0011] Furthermore, the air duct is located below the electrical control box, and a connecting port is provided on the air duct, with the dust discharge port corresponding to the connecting port.

[0012] Furthermore, the automatic dust removal system of the electrical control box also includes a fixed frame, on which the air duct is mounted, and the air duct has a cuboid structure.

[0013] An air conditioner includes an evaporator and an automatic dust removal system with an electrical control box as described above. The evaporator is disposed between a filter assembly and an air supply assembly. The filter assembly is provided with a fresh air inlet and a third actuator. Outside air enters through the fresh air inlet. The third actuator is signal-connected to a control module, and the control module transmits a signal to the third actuator to open or close the fresh air inlet. The air supply assembly is also provided with an air outlet and a fourth actuator. The fourth actuator is signal-connected to the control module, and the control module transmits a signal to the fourth actuator to open or close the air outlet.

[0014] A dust removal control method includes an air conditioner as described above. A control module is connected to the on / off signal of the air conditioner. When the air conditioner is detected to be in a closed state and the light sensor detects that the dust thickness at the bottom of the electrical control box is greater than a preset value N, the automatic dust removal system of the air conditioner's electrical control box operates as follows:

[0015] Step 1: The control module transmits signals to the third and fourth actuators respectively, so that the third actuator closes the fresh air inlet and the fourth actuator closes the air supply outlet;

[0016] Step 2: The control module transmits signals to the first actuator and the second actuator respectively, so that the first actuator opens the air valve and the second actuator opens the dust collection port;

[0017] Step 3: Turn on the electrostatic dust removal device and start the fan to draw air from inside the air conditioner so that the dust in the electrical control box is attracted into the electrostatic dust removal device for ionization and dust removal.

[0018] A dust removal control method includes the dust removal control method described above, and further includes: setting a time detector on the air conditioner, the time detector being used to set a dust removal cycle, and a control module being signal-connected to the time detector; when the air conditioner is detected to be in a closed state and the time detector reaches a preset value T, the control module activates the automatic dust removal system of the air conditioner's electrical control box.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] According to an embodiment of the present invention, an automatic dust removal system for an electrical control box is provided. Please refer to [link / reference]. Figures 1 to 5 The system includes: an electrical control box 1, with a dust outlet 11 and a light sensor 12 at its bottom. The dust outlet 11 is used to discharge dust from inside the electrical control box 1, and the light sensor 12 is used to detect the thickness of the dust. A dust collection component 2 is connected at one end to the dust outlet 11, and a damper 22 and a first actuator 23 are provided at the other end. The dust collection component 2 is used to collect and transport the dust discharged from the dust outlet 11. The first actuator 23 controls the opening and closing of the damper 22. A filter assembly 3 is connected to the dust collection component 2, and an electrostatic dust removal device 31 is provided inside the filter assembly 3. An air supply assembly 4 is connected to the filter assembly 3, and a dust collection port 41 and a fan 4 are provided on the air supply assembly 4. 2. Second actuator 45, which controls the opening and closing of dust removal port 41; Control module, which is connected to light sensor 12, first actuator 23, electrostatic dust removal device 31, fan 42 and second actuator 45 respectively; When light sensor 12 detects that the dust thickness at the bottom of the electrical control box 1 is greater than the preset value N, light sensor 12 transmits the signal to the control module, and the control module starts the first actuator 23 and the second actuator 45 to open the air valve 22 and dust removal port 41 respectively, and at the same time starts the fan 42 and electrostatic dust removal device 31. The electrical control box 1 generates negative pressure to suck the dust inside the electrical control box 1 to the electrostatic dust removal device 31 through the dust suction component 2 for ionization, and then discharges it from the dust removal port 41.

[0033] In this embodiment of the automatic dust removal system for the electrical control box, when the light sensor 12 detects that the dust thickness at the bottom of the electrical control box 1 reaches a preset value N, it transmits a signal to the control module. The control module then activates the first actuator 23 and the second actuator 45. The first actuator 23 and the second actuator 45 respectively open the air valve 22 and the dust collection port 41. Then, the fan 42 of the air supply assembly 4 and the electrostatic dust removal device 31 of the filter assembly 3 are activated. At this time, a huge negative pressure is generated inside the electrical control box 1, causing the dust inside the box to be discharged from the dust outlet 11 and enter the dust collection component 2. The dust collection component 2, acting as a dust flow channel, carries the adsorbed dust into the electrostatic dust removal device 31 of the filter assembly 3. After being ionized and decomposed by the electrostatic dust removal device 31, a very small amount of unionized dust, along with the internal airflow, is discharged from the dust collection port 41. This automatic dust removal device for the electrical control box eliminates the need for manual disassembly and cleaning of the electrical control box 1, and achieves automatic cleaning, saving time and effort and significantly reducing maintenance costs. The automatic dust removal device for the electrical control box in this embodiment solves the technical problem in the related art that automatic dust removal cannot be performed inside the electrical control box.

[0034] Specifically, the outer shells of the filter assembly 3 and the air supply assembly 4 are both made of foam board, which fully seals the outdoor unit of the automatic dust removal system in the electrical control box, so that a large negative pressure is generated inside the fan 42 when it is working to achieve the function of adsorbing dust.

[0035] Specifically, the electrostatic dust removal device 31 consists of two main parts: an electrostatic dust collection unit and a high-voltage generator. The high-voltage generator converts low voltage into DC high voltage through an oscillation circuit, a boost circuit, and a rectifier and filter circuit, and applies it to the discharge electrode (corona wire) and dust collection plate of the dust collection unit. Under the action of high voltage, the corona wire and the dust collection plate generate a strong corona discharge, ionizing the air and forming an electrostatic field in the area. When the air containing dust passes through this area, the dust is charged and collected on the dust collection plate under the action of the electrostatic field, thereby achieving the function of ionizing and decomposing dust.

[0036] Specifically, the dust removal port 41 is also equipped with a damper blade, which works in conjunction with the second actuator 45 to open and close the dust removal port 41 and adjust the opening degree of the dust removal port 41.

[0037] See Figures 2 to 4 In the automatic dust removal system of the electrical control box in this embodiment, the dust collection component 2 also includes an air duct 21, which is connected to the dust discharge port 11; and an air valve 22, which is disposed between the air duct 21 and the filter assembly 3. One end of the air duct 21 of the dust collection component 2 is connected to the dust discharge port 11, and the other end is connected to the filter assembly 3. An air valve 22 and a first actuator 23 are disposed on the air duct 21. The first actuator 23 is connected to the control module via a signal, and the control module transmits a signal to the first actuator 23, which controls the opening and closing of the air valve 22.

[0038] See Figure 2 The air valve 22 adopts a blade structure and is used in conjunction with the first actuator 23. It not only controls the opening and closing of the air duct 21, but also adjusts the opening degree of the air duct 21 outlet.

[0039] See Figure 3 The length of the air duct 21 can be set according to the actual size of the work site. In the automatic dust removal system of the electrical control box in this embodiment, the electrical control box 1 is installed outdoors, and the filter assembly 3 and the air supply assembly 4 are installed indoors. The electrical control box 1 is connected to the indoor equipment by adjusting the length of the air duct 21.

[0040] See Figure 4 In the automatic dust removal system of the electrical control box in this embodiment, a bracket 32 ​​is provided on the side of the filter assembly 3 near the air supply assembly 4, and the electrostatic dust removal device 31 is fixed on the bracket 32. The dust drawn in is ionized and decomposed inside the filter assembly 3.

[0041] See Figure 4 In the automatic dust removal system of the electrical control box in this embodiment, there are multiple brackets 32 and multiple electrostatic dust removal devices 31, with each electrostatic dust removal device 31 arranged and fixed on a separate bracket 32. The multiple brackets 32 are arranged in a grid, with one electrostatic dust removal device 31 placed in each grid. When dust removal is performed on the electrical control box 1, air flows from the air duct 21 through the filter assembly 3 and is blown towards the air supply assembly 4, with some dust being blown out from the dust removal port 41 of the air supply assembly 4.

[0042] See Figure 3 In the automatic dust removal system of the electrical control box in this embodiment, the dust discharge port 11 is composed of several micro-holes. Inside the electrical control box 1, the top of the dust discharge port 11 is covered with accumulated dust. The dust discharge port 11 is composed of dense micro-holes to prevent the falling dust from falling into the air duct 21 connected to the dust discharge port 11, thereby providing a smooth adsorption channel for the air duct 21 and ensuring that the dust can normally enter the electrostatic dust removal device 31.

[0043] See Figure 3 In the automatic dust removal system of the electrical control box in this embodiment, the air duct 21 is located below the electrical control box 1, and the air duct 21 is provided with a connecting port, with the dust discharge port 11 corresponding to the connecting port. The connecting port of the air duct 21 is located below the dust discharge port 11 of the electrical control box 1 to facilitate better suction of dust inside the electrical control box 1.

[0044] See Figure 4 In the automatic dust removal system of the electrical control box in this embodiment, the system also includes a fixing frame 6, and an air duct 21 is mounted on the fixing frame 6. The air duct 21 has a cuboid structure. The cuboid structure of the air duct 21 facilitates more secure fixation to the fixing frame 6, thereby improving the robustness of the automatic dust removal system of the electrical control box.

[0045] See Figure 1 In this embodiment of the air conditioner, there are an automatic dust removal system and an evaporator 5 as described above. The evaporator 5 is disposed between the filter assembly 3 and the air supply assembly 4. The filter assembly 3 is provided with a fresh air inlet 33 and a third actuator 34. Outside air enters through the fresh air inlet 33. The third actuator 34 is signal-connected to the control module. The control module transmits a signal to the third actuator 34 to open or close the fresh air inlet 33. The air supply assembly 4 is also provided with an air outlet 43 and a fourth actuator 44. The fourth actuator 44 is signal-connected to the control module. The control module transmits a signal to the fourth actuator 44 to open or close the air outlet 43. The air conditioner's electrical control box 1, compressor, condenser fan, and condenser are located outdoors, while the filter assembly 3, evaporator 5, and air supply assembly 4 are located indoors. The air conditioner's fresh air inlet 33 is located on the filter assembly 3, and the third actuator 34 controls the opening and closing of the fresh air inlet 33 according to the signal transmitted by the control module. The air conditioner's air supply outlet 43 is located on the air supply assembly 4, and the fourth actuator 44 controls the opening and closing of the air supply outlet 43 according to the signal transmitted by the control module.

[0046] See Figure 5 In the dust removal control method of this embodiment, an air conditioner as described above is used. The control module is connected to the switch signal of the air conditioner. When the air conditioner is detected to be in a closed state and the light sensor 12 detects that the dust thickness at the bottom of the electrical control box 1 is greater than the preset value N, the operation steps of the automatic dust removal system of the air conditioner's electrical control box are as follows:

[0047] Step 1: The control module transmits signals to the third actuator 34 and the fourth actuator 44 respectively, so that the third actuator 34 closes the fresh air inlet 33 and the fourth actuator 44 closes the air outlet 43.

[0048] Step 2: The control module transmits signals to the first actuator 23 and the second actuator 45 respectively, so that the first actuator 23 opens the air valve 22 and the second actuator 45 opens the dust collection port 41.

[0049] Step 3: Turn on the electrostatic dust removal device 31 and start the fan 42 to draw air from inside the air conditioner so that the dust in the electrical control box 1 is adsorbed and enters the electrostatic dust removal device 31 for ionization and dust removal.

[0050] When the air conditioner is not running, the light sensor 12 detects that the dust layer thickness is greater than the set value N. This causes the third actuator 34 to close the fresh air inlet 33, and the fourth actuator 44 to close the supply air outlet 43. The first actuator 23 is activated, opening the air valve 22, and the second actuator 45 is activated, opening the dust collection port 41. The fan 42 and the electrostatic precipitator 31 are then activated. At this moment, the electrical control box 1 instantly generates a huge negative pressure, drawing the dust layer covering or suspended inside the electrical control box 1 through the air duct 21 into the filter assembly 3. Upon encountering the electrostatic precipitator, the dust layer is decomposed and ionized under high pressure. The remaining unionized dust is blown out of the unit through the dust collection port 41.

[0051] When the light sensor 12 detects that the thickness of the dust layer is less than the set value N, the control module first transmits a signal to the first actuator 23 and the second actuator 45, causing the first actuator 23 to close the air valve 22, thereby closing the air duct 21, and the second actuator 45 to close the dust removal port 41; then, the fan 42 and the electrostatic dust removal device 31 are turned off; next, the control module transmits a signal to the third actuator 34 and the fourth actuator 44, causing the third actuator 34 to open the fresh air inlet 33 and the fourth actuator 44 to open the air supply port 43, that is, the dust removal and cleaning process ends.

[0052] When the air conditioning unit is working, the air conditioning unit will not enter the dust removal control program temporarily. After the air conditioning unit finishes normal operation, the above-mentioned dust removal control method will be executed.

[0053] See Figure 5 In this embodiment of the dust removal control method, the method further includes setting a time detector on the air conditioner. The time detector is used to set the dust removal cycle, and the control module is signal-connected to the time detector. When the air conditioner is detected to be in a closed state and the time detector reaches a preset value T, the control module activates the automatic dust removal system in the electrical control box. The time detector on the air conditioner, signal-connected to the control module, allows the customer to set the detection cycle according to the environment of the air conditioner unit. When the time detector reaches the preset value T, the above dust removal and cleaning procedure is repeated. This procedure is connected in parallel with the light sensor 12 detecting whether the dust layer thickness reaches a preset value N; both can execute the dust removal and cleaning procedure when they reach their preset values. The same unit does not execute this dust removal control method during operation.
