[0037] Combine the following Figure 1 to Figure 7 The technical solution provided by the utility model is described in more detail.

[0038] The utility model provides a self-cleaning process plate for an air conditioner outdoor unit, such as Figure 1 As shown, the board body 100 , a heat-generating element 110 and a heat-conducting layer 120 are included. The heat-generating element 110 is disposed on the board body 100 , and the heat-conducting layer 120 is disposed on the heat-generating element 110 .

[0039] The board body 100 is provided with a power supply interface 150 , and the power supply interface 150 is connected to the heating element 110 .

[0040] The utility model provides a self-cleaning process plate for an air-conditioning outdoor unit, comprising a plate body 100, a heating element 110 and a heat-conducting layer 120. The plate body 100 is used to carry the air-conditioning outdoor unit, and then the plate body 100 is transported through a conveying line 210 to complete processes such as refrigerant filling and functional operation testing. A heating element 110 is arranged on the plate body 100, and a heat-conducting layer 120 is arranged on the heating element 110. An electrical interface 150 is arranged on the plate body 100, and the electrical interface 150 is connected to the heating element 110 to heat the heating element 110 through the electrical interface 150 on the plate body 100. The heated heating element 110 conducts heat through the heat-conducting layer 120, and then the dirty mixture such as the refrigerant remaining on the plate body 100 is subjected to thermal evaporation treatment, thereby realizing rapid cleaning of the self-cleaning process plate for the air-conditioning outdoor unit. The cleaning process is simple and quick, which improves work efficiency, reduces labor costs and labor intensity, improves product cleanliness, reduces the failure rate of air conditioner dirtiness and blockage, and effectively ensures stable operation of the air-conditioning outdoor unit.

[0041] Compared with the prior art, the self-cleaning process plate of the air conditioner outdoor unit provided by the utility model is heated by the heating element 110, thereby achieving the treatment of dirty mixtures and avoiding the problem of waste of manpower and material resources caused by manual cleaning; at the same time, it solves the problem that the externally installed automatic cleaning equipment cannot effectively clean the process plate, and avoids the safety risks and cost waste caused by frequent disassembly, cleaning and maintenance.

[0042] It can be understood that the heat-conducting layer 120 is arranged above the heating element 110, and can conduct the heat generated by the heating element 110, make the heat distribution even, and appropriately increase the heat transfer range, thereby ensuring that the dirty mixture above the plate body 100 can be removed at one time, thereby realizing the thermal evaporation treatment of the dirty mixture on the self-cleaning process plate of the air conditioner outdoor unit.

[0043] The installation positions of the heat-conducting layer 120 and the heating element 110 are determined according to the position of the dirty mixture such as the refrigerant which is likely to remain on the plate body 100 during the actual operation. Since the position of the dirty mixture is limited to one area, when the self-cleaning process plate of the air conditioner outdoor unit is actually set, the heating element 110 and the heat-conducting layer 120 are set in the designated area of ​​the residual dirty mixture.

[0044] It should be noted here that the dirty mixture mainly refers to the refrigerant, which is liquid at normal temperature and pressure. The most commonly used refrigerants are R32 and R410A. The critical temperature of R32 is 51.7 degrees Celsius, and the critical temperature of R410A is 96.67 degrees Celsius. The heating temperature of the heating element 110 can meet the requirements of heating and evaporating the dirty mixture, which is sufficient to evaporate the refrigerant remaining on the self-cleaning process board of the air conditioner outdoor unit.

[0045] In some embodiments of the present invention, Figure 2 As shown, a positioning groove 140 is provided on the board body 100 , the heat generating element 110 and the heat conducting layer 120 are both arranged in the positioning groove 140 , and the top surface of the heat conducting layer 120 is flush with the top surface of the board body 100 .

[0046] In some of the above-mentioned embodiments of the utility model, by setting a positioning groove 140 on the plate body 100, the heating element 110 and the heat-conducting layer 120 are both set in the positioning groove 140, and the top surface of the heat-conducting layer 120 is flush with the top surface of the plate body 100, so that the heat is conducted to the top surface of the plate body 100 through the heat-conducting layer 120, so that the thickness and other dimensions of the plate body 100 do not change, and the corresponding other components on the plate body 100 for installing the air conditioner outdoor unit do not need to change the setting position.

[0047] In some embodiments of the present invention, the heat-conducting layer 120 is made of heat-conducting silica gel, and the heat-conducting silica gel is filled in the positioning groove 140 to wrap around the heating element 110 .

[0048] In some of the above-mentioned embodiments of the utility model, the heat-conducting layer 120 is made of heat-conducting silicone, and the heat-conducting silicone is used to make the heat distribution more uniform to avoid local overheating of the process board, and the heat-conducting silicone is filled in the positioning groove 140 to wrap around the heating element 110, thereby ensuring that the heat of the heating element 110 can be used for thermal evaporation of the dirty mixture in a larger range, improving the cleaning effect, improving the cleaning efficiency, reducing labor costs and labor intensity, improving product cleanliness, reducing the failure rate of air conditioner dirt and blockage, and effectively ensuring the stable operation of the air conditioner outdoor unit.

[0049] In some embodiments of the present invention, Figure 2-Figure 3 As shown, a heat-conducting insulating plate 130 is further included. The heat-conducting insulating plate 130 is disposed on the plate body 100 , and the heat-conducting layer 120 is connected to the heat-conducting insulating plate 130 .

[0050] In some of the above-mentioned embodiments of the utility model, a heat-conducting insulating plate 130 is further provided on the plate body 100, and the heat-conducting insulating plate 130 is connected to the plate body 100, and the heat-conducting layer 120 is connected to the heat-conducting insulating plate 130, and the heat derived from the heat-conducting layer 120 is conducted to the heat-conducting insulating plate 130, and the dirty mixture is cleaned by the heat-conducting insulating plate 130, and the heat-conducting insulating plate 130 is connected to the plate body 100, which can increase the strength of the plate body 100 and ensure that the plate body 100 can meet the load-bearing capacity required for the transportation of the air-conditioning outdoor unit.

[0051] Specifically, the thermally conductive insulating plate 130 is connected to the plate body 100 by bolts, and countersunk holes corresponding to the bolt nuts are provided on the thermally conductive insulating plate 130 to prevent the bolts from leaking out of the surface of the thermally conductive insulating plate 130; at the same time, the thermally conductive insulating plate 130 and the plate body 100 can be separated, and when the thermally conductive insulating plate 130 is damaged or destroyed, it can be replaced in time.

[0052] Furthermore, the heat-conducting insulating plate 130 is made of polyimide, and has the characteristics of high mechanical strength and high temperature resistance, which effectively ensures the load-bearing capacity of the heat-conducting insulating plate 130 and the plate body 100 .

[0053] In some embodiments of the present invention, the thermally conductive insulating plate 130 is disposed in the countersunk groove 220 on the plate body 100 .

[0054] In some embodiments of the present invention, the heating element 110 is a PTC heating tube.

[0055] In some of the above-mentioned embodiments of the utility model, the PTC heating tube is a solid constant temperature heating tube with the characteristics of safety, energy saving, long life and environmental protection. It is composed of a PTC ceramic chip, an electrode plate, wires, a polyimide insulation layer and an aluminum shell. Multiple wires are connected to the electrode plate and led out to the outside of the plate body 100 to form a power interface 150 fixed on the plate body 100.

[0056] In addition, the maximum heating temperature of the PTC heating tube can reach 200 degrees Celsius, which is sufficient to evaporate the refrigerant and other dirty mixtures remaining on the process board, and the board body 100 will not be affected by the heating temperature of the PTC heating tube and can work normally.

[0057] It should be noted that the PTC heating principle is based on the characteristics of the positive temperature coefficient thermistor (PTC). PTC is a temperature-sensitive semiconductor resistor. When a certain temperature (Curie temperature) is exceeded, its resistance value will increase stepwise as the temperature rises.

[0058] The utility model also provides an air conditioner outdoor unit production line, such as Figure 4-Figure 5 As shown, it includes a conveyor line 210 and an air conditioner outdoor unit self-cleaning process plate, and the conveyor line 210 is used to convey the air conditioner outdoor unit self-cleaning process plate;

[0059] The conveyor line 210 is provided with an electric docking device and a positioning device, the positioning device includes a blocker 160 and a driving structure (not shown in the figure), the blocker 160 is arranged in the conveying direction of the conveyor line 210, and the driving structure (not shown in the figure) is connected to the blocker 160 to drive the blocker 160 to move up and down to position the self-cleaning process plate of the air conditioner outdoor unit;

[0060] The power-on docking device includes a moving component 170 and a connection terminal 180 . The connection terminal 180 is disposed on the moving component 170 . The moving component 170 drives the connection terminal 180 to move back and forth to connect or disconnect the power-on interface 150 .

[0061] The utility model also provides an air-conditioning outdoor unit production line, including a conveyor line 210 and an air-conditioning outdoor unit self-cleaning process board. After the air-conditioning outdoor unit completes all processes on the air-conditioning outdoor unit self-cleaning process board, the conveyor line 210 is used to convey the air-conditioning outdoor unit self-cleaning process board. The conveyor line 210 can convey the air-conditioning outdoor unit self-cleaning process board to the self-cleaning position, complete the self-cleaning of the air-conditioning outdoor unit self-cleaning process board, and then continue to convey it through the conveyor line 210 to complete the next cycle process; a positioning device and a power-on docking device are provided on the conveyor line 210, and the positioning device includes a blocker 160 and a driving structure (not shown in the figure). The blocker 160 is arranged in the conveying direction of the conveyor line 210, and the driving structure (not shown in the figure) is connected to the blocker 160 to drive the blocker 160 to move up and down to position the air-conditioning outdoor unit self-cleaning process board, so that the air-conditioning outdoor unit self-cleaning process board stays in the self-cleaning position.

[0062] The power-on docking device includes a moving component 170 and a wiring terminal 180. The wiring terminal 180 is arranged on the moving component 170. The moving component 170 drives the wiring terminal 180 to move back and forth to connect or disconnect the power-on interface 150. When the positioning device positions the self-cleaning process board of the air-conditioning outdoor unit in the self-cleaning position, the moving component 170 drives the wiring terminal 180 to move to connect the power-on interface 150. At this time, the power is turned on, and the heating element 110 starts to work. The heat generated by the heating element 110 is dissipated through the heat conduction layer 120 and the heat-conducting insulating plate 130 to evaporate the dirty mixture on the heat-conducting insulating plate 130, thereby completing the thermal evaporation treatment of the dirty mixture.

[0063] It should be noted here that the conveyor line 210 is used to convey the air-conditioning outdoor unit self-cleaning process board to the self-cleaning position after all processes are completed on the air-conditioning outdoor unit self-cleaning process board. After cleaning is completed, the air-conditioning outdoor unit self-cleaning process board is conveyed to the starting point of the next cycle process to continue to complete the refrigerant filling of the air-conditioning outdoor unit, the whole machine function operation test and other processes.

[0064] For example, in some embodiments, Figure 6 As shown, it also includes a plate delivery line 200. The plate delivery line 200 and the conveyor line 210 are arranged in the upper and lower layers. The plate delivery line 200 is used to transport the air-conditioning outdoor unit to complete the refrigerant filling of the air-conditioning outdoor unit, the whole machine function operation test and other processes. The conveyor line 210 is used to transport the self-cleaning process board of the air-conditioning outdoor unit to complete the self-cleaning, and then transport the self-cleaning process board of the air-conditioning outdoor unit to the plate delivery line 200.

[0065] It can be understood that the driving structure (not shown in the figure) is used to drive the blocker 160 to move up and down, thereby ensuring that the blocker 160 can extend upward to limit the self-cleaning process plate of the air-conditioning outdoor unit, or move downward to release the self-cleaning process plate of the air-conditioning outdoor unit; or move downward to limit the self-cleaning process plate of the air-conditioning outdoor unit, and move upward to release the self-cleaning process plate of the air-conditioning outdoor unit.

[0066] In addition, in order to increase the self-cleaning efficiency of the air conditioner outdoor unit self-cleaning process board, multiple sets of positioning devices and power-on docking devices can be set on the conveyor line 210, which can complete self-cleaning of multiple sets of air conditioner outdoor unit self-cleaning process boards at the same time.

[0067] In some other embodiments, a driving structure (not shown in the figure) is used to drive the blocker 160 to move tiltedly or forward and backward to achieve the positioning of the self-cleaning process plate of the air conditioner outdoor unit.

[0068] Correspondingly, the moving component 170 is an upper electric cylinder, and the moving component 170 is used to drive the connection terminal 180 to move, so as to complete the electrical connection between the connection terminal 180 and the power interface 150, and complete the power connection of the heating element 110.

[0069] It is understandable that the function of the moving component 170 is to realize the reciprocating movement of the terminal 180. In some other embodiments, the moving component 170 can also use the reciprocating moving component in the prior art to complete the driving of the terminal 180, thereby ensuring the docking of the terminal 180 and the power interface 150.

[0070] In some embodiments of the present invention, the moving assembly 170 is a three-axis guide rod cylinder.

[0071] In some of the above-mentioned embodiments of the present invention, the moving assembly 170 adopts a three-axis guide rod cylinder, which has higher ability to resist torque and lateral load.

[0072] Specifically, the three-axis guide rod cylinder is mainly composed of four parts: the cavity, the piston, the cylinder push rod, and the spring. In addition to the cylinder push rod axis, the push rod also has two guide rods, which have high anti-torque and anti-lateral load capabilities. When the cylinder is working, the solenoid valve controls the air source to enter from the rear chamber of the piston, and the boost pushes the piston to drive the cylinder push rod to extend. When the cylinder reaches the maximum stroke, the terminal 180 is connected to the power interface 150 on the board body 100. After the power-on heating is completed, the solenoid valve is reversed, and the air source enters from the front chamber of the piston, pushing the piston to drive the cylinder push rod to move to the rear chamber of the cylinder, and the terminal 180 is disconnected from the power interface 150 on the board body 100.

[0073] In some embodiments of the present invention, a limit block 190 is provided on the self-cleaning process board of the air conditioner outdoor unit, and the limit block 190 corresponds to the position of the blocker 160 .

[0074] In some of the above-mentioned embodiments of the utility model, a limit block 190 is provided on the self-cleaning process plate of the outdoor unit of the air conditioner, and the limit block 190 corresponds to the position of the blocker 160. When the self-cleaning process plate of the outdoor unit of the air conditioner follows the conveyor, the blocker 160 is driven by a driving structure (not shown in the figure) to move up and down to limit the self-cleaning process plate of the outdoor unit of the air conditioner. At this time, the blocker 160 is in rigid contact with the self-cleaning process plate of the outdoor unit of the air conditioner. In order to ensure that the self-cleaning process plate of the outdoor unit of the air conditioner has a longer service life, a limit block 190 is provided on the self-cleaning process plate of the outdoor unit of the air conditioner. The limit block 190 is used to directly contact with the blocker 160, thereby effectively protecting the self-cleaning process plate of the outdoor unit of the air conditioner, improving its durability and increasing its service life.

[0075] Optionally, the limiting block 190 is made of metal.

[0076] In some embodiments of the present invention, a detection device is further included. The detection device includes a beam sensor. The beam sensor includes a transmitting end and a receiving end. The transmitting end and the receiving end are respectively arranged on both sides of the conveying line 210.

[0077] In some of the above-mentioned embodiments of the utility model, the detection device is used to detect whether the self-cleaning process board of the air-conditioning outdoor unit enters the self-cleaning position area. When the detection device detects that the self-cleaning process board of the air-conditioning outdoor unit enters the self-cleaning position area, the control driving structure (not shown in the figure) drives the blocker 160 to move up and down to limit the self-cleaning process board of the air-conditioning outdoor unit. The moving component 170 is extended to connect the power terminal and the power interface 150. The power is turned on to complete the heating of the heating element 110. When it is detected that the heating temperature of the heat-conducting insulating plate 130 on the self-cleaning process board of the air-conditioning outdoor unit reaches the set range, the moving component 170 is controlled to return to the starting position to disconnect the power terminal from the power interface 150. At this time, the driving structure (not shown in the figure) drives the blocker 160 to move up and down to release the self-cleaning process board of the air-conditioning outdoor unit, and the conveyor line 210 continues to convey it.

[0078] Specifically, the detection device is a through-beam sensor, which includes a transmitting end and a receiving end, and the transmitting end and the receiving end are respectively arranged on both sides of the conveying line 210 .

[0079] Since the through-beam sensor is a prior art, it will not be described in detail here. When the through-beam sensor is applied to the air-conditioning outdoor unit production line provided by the utility model, it can automatically detect the self-cleaning process board of the air-conditioning outdoor unit, realize automatic cleaning of the self-cleaning process board of the air-conditioning outdoor unit, and greatly improve work efficiency.

[0080] Furthermore, the detection device also includes a heat sensor, which is arranged on the self-cleaning process board of the air conditioner outdoor unit.

[0081] In this further improvement scheme, by setting a heat sensor on the self-cleaning process plate of the air conditioner outdoor unit, the heat sensor can detect the heating temperature of the self-cleaning process plate of the air conditioner outdoor unit, ensuring that the dirty mixture can be evaporated and removed, effectively ensuring the cleaning effect.

[0082] Furthermore, a thermal sensor is disposed below the thermally conductive insulating plate 130 to detect the temperature of the thermally conductive insulating plate 130. Since the thermally conductive insulating plate 130 is in direct contact with the dirty mixture, when the temperature of the thermally conductive insulating plate 130 reaches the set temperature, it can ensure that the dirty mixture can be evaporated and removed, thereby effectively ensuring the cleaning effect.
