[0044] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.
[0045] For the sake of explanation, Figure 1 , Figure 2 , Figure 3 and Figure 4 The condenser assembly includes a housing and a drawer, wherein the housing is composed of a cap 111, a condenser upper cover 112 and a condenser lower cover 113, and a Figure 1 and Figure 2 The cap 111 is mounted on the upper surface of the condenser upper cover 112, the condenser upper cover 112 is engaged with the condenser lower cover 113, the condenser upper cover 112 and the condenser lower cover 113 form a receiving cavity, and the drawer is inserted into the receiving cavity. Figure 3 As shown, the drawer includes a drawer upper cover 131 and a drawer lower cover 132, wherein the drawer upper cover 131 is installed on the drawer lower cover 132. It is worth noting that a cavity is provided in the drawer lower cover 132, and a filter 134 is installed in the cavity. It is worth noting that water is stored in the cavity. In order to facilitate the water to flow into the dryer, a hole is opened on the bottom wall of the cavity. In addition, in combination with Figure 1 and Figure 3In order to facilitate the control of the flowability of water in the hole, a valve cover 140 is installed in the cavity. A sealing ring 142 is installed on one end of the valve cover 140, and the hole is sealed by the valve cover 140 and the sealing ring 142; a connecting shaft 143 is provided on the two side walls of the other end of the valve cover 140, and the connecting shaft 143 is movably connected to the inner wall of the cavity, so that the valve cover 140 can rotate with the connecting shaft 143 as the rotation center, thereby realizing the opening and closing between the valve cover 140 and the hole in the inner cavity.
[0046] Furthermore, in order to control the opening and closing of the hole and the degree of opening and closing, a torsion spring 141 is installed on the side where the connecting shaft 143 is provided, and both ends of the torsion spring 141 are installed on the connecting shaft 143, and the torsion spring 141 is in contact with the bottom wall of the cavity; in addition, a movable groove 133 is provided on one side of the drawer lower cover 132, and the connecting shaft 143 on one side of the valve cover 140 extends out of the movable groove 133, and an external lever 150 is installed on the protruding end of the connecting shaft 143, that is, the external lever 150 is located in the movable groove 133.
[0047] It is worth noting that the outer lever 150 is engaged with the protruding end of the connecting shaft 143. When either the outer lever 150 or the valve cover 140 rotates, the other one will also rotate accordingly. Figure 1 and Figure 2 A mounting groove 114 is provided on the lower cover 113 of the condenser, and a solenoid valve 120 is arranged in the mounting groove 114. The top end of the valve stem 121 on the solenoid valve 120 contacts the outer lever 150. When the solenoid valve 120 is working, the valve stem 121 is controlled to move up and down, thereby driving the outer lever 150 to rotate, that is, driving the valve cover 140 to rotate.
[0048] In the prior art, during the production process of the condenser assembly, the various parts of its accessories are generally produced by the manufacturing manufacturers. During the production process, different manufacturers only focus on whether the performance of the simply processed parts themselves meets the requirements. Therefore, whether the assembled condenser assembly meets the requirements is not involved. For example, during the assembly process of the condenser assembly, there are certain deviations in the welding, assembly and other processes, which leads to deviations in the overall quality of the entire device assembled later, and cannot meet the needs of the high-end market.
[0049] For the condenser assembly, the key point is to control the opening and closing degree between the valve cover 140 and the hole, so as to control the amount of water flowing out of the condenser assembly, so as to achieve the purpose of accurately controlling the amount of water. On the one hand, it can effectively ensure the ratio of detergent and water added by the subsequent dryer when washing clothes, which is beneficial to the washing of clothes; on the other hand, it can make full use of water resources, thereby saving water resources.
[0050] In order to ensure that subsequent clothes dryer products have high production quality, it is particularly important to test the performance of the valve cover 140 in the condenser assembly.
[0051] Example 1
[0052] In order to solve the above problems, combined Figure 5 , a detection device for a clothes dryer condenser assembly of this embodiment includes a positioning fixture 300, a pressing positioning unit, a pushing positioning unit and a pressure probe 700 installed on a workbench 200; wherein, as Figure 5 As shown, the condenser assembly has been installed in the positioning jig 300. In order to ensure the accuracy of the subsequent performance test of the valve cover 140 in the condenser assembly, that is, to ensure the accuracy of whether the opening and closing degree between the valve cover 140 and the hole meets the requirements, this embodiment presses the condenser assembly in the positioning jig 300 by pressing the positioning unit, so as to achieve the stability of the longitudinal installation of the condenser assembly; at the same time, the condenser assembly is positioned laterally by pushing the positioning unit, so as to ensure the stability and firmness of the condenser assembly installed in the positioning jig 300.
[0053] In addition, the pressure probe 700 of the present embodiment is vertically mounted on the workbench 200 and passes through the positioning fixture 300. When the condenser assembly is mounted on the positioning fixture 300, the top end of the pressure probe 700 contacts one end of the valve cover 140, and the force value on the pressure sensor connected to the pressure probe 700 is zero.
[0054] In this embodiment, the pressure probe 700 contacts one end of the valve cover 140 on which the sealing ring 142 is installed. The pressure probe 700 is subsequently controlled to move up and down, thereby driving the valve cover 140 to rotate. During the whole process, the magnitude of the applied force is measured by the pressure probe 700, and the result is compared with the preset force value range to detect whether it meets the requirements, that is, to detect the performance of the valve cover 140 in the condenser assembly.
[0055] In this embodiment, the pressure probe 700 is driven by a motor to move up and down.
[0056] It is worth noting that the upper surface of the positioning fixture 300 of this embodiment may be provided with a corresponding groove, the shape of which matches the shape of the lower part of the condenser assembly, thereby facilitating the installation of the condenser assembly. In addition, the drawers in the condenser assembly of this embodiment are assembled together in an inserting manner. Therefore, during the installation process, the drawer is movably connected to the shell, and the valve cover 140 is installed on the drawer lower cover 132. Therefore, in order to ensure the accuracy of the test results, the condenser assembly needs to be fixed by the combined action of the compression positioning unit and the push positioning unit. When the push positioning unit of this embodiment is fixed horizontally, the push positioning unit contacts the drawer, and the push positioning unit fixes the insertion direction of the drawer.
[0057] A detection method of a detection device for a clothes dryer condenser assembly of this embodiment adopts the detection device for a clothes dryer condenser assembly of this embodiment, and the process is as follows:
[0058] Step a, placing the assembled condenser assembly on the positioning fixture 300;
[0059] Step b, starting the pressing and positioning unit and the pushing and positioning unit, realizing longitudinal positioning of the condenser assembly by the pressing and positioning unit; realizing transverse positioning of the condenser assembly by the pushing and positioning unit;
[0060] The valve cover 140 is in contact with the pressure probe 700, and the force value detected by the pressure probe 700 is zero, that is, Fig. 9 As shown, at this time, the top end of the pressure probe 700 is at the initial position a;
[0061] Step c: The motor drives the pressure probe 700 to move upward. Under the action of the torsion spring 141 and the connecting shaft 143, the valve cover 140 rotates with the connecting shaft 143 as the rotation center. Fig. 9 As shown, when the top end of the pressure probe 700 moves upward to position b, the force f1 at this time is detected by the pressure probe 700, and the detected result is compared with the standard range F1-F2; if the detected result is within the standard range, it is qualified, and if it is not within the standard range, it is unqualified;
[0062] That is, when F1≤f1≤F2, the condenser always becomes a qualified product; when f1<F1 or f1>F2, the condenser always becomes an unqualified product.
[0063] It is worth noting that when the condenser assembly fails to meet the requirements, stop testing it, replace the next condenser assembly and re-test it according to the above steps.
[0064] Step d: When the condenser assembly tested in step c becomes a qualified product, the motor continues to drive the pressure probe 700 to move upward, such as Fig. 9 As shown, when the top end of the pressure probe 700 is controlled to move to position c, the force f2 at this time is detected by the pressure probe 700, and the detected result is compared with the standard range F3-F4; if the detected result is within the standard range, it is qualified, and if it is not within the standard range, it is unqualified;
[0065] That is, when F3≤f2≤F4, the condenser always becomes a secondary qualified product; when f2<F3 or f2>F4, the condenser always becomes an unqualified product.
[0066] It is worth noting that when the condenser assembly fails to meet the requirements, stop testing it, replace the next condenser assembly and re-test it according to the above steps.
[0067] Step e: When the condenser assembly tested in step d becomes a secondary qualified product, the solenoid valve 120 is energized to move the valve stem 121 upward, and the valve stem 121 pushes the outer lever 150 to rotate upward, that is, the valve cover 140 is driven to rotate upward. During this process, the valve cover 140 is separated from the pressure probe 700. Fig. 9 As shown, the control valve cover 140 moves to the maximum position d, and the force f3 at this time is detected by the pressure probe 700. If the magnitude of f3 is zero, it is a qualified product for three times; if the magnitude of f3 is not zero, it is a failed product;
[0068] When the condenser assembly fails to meet the requirements, stop testing it, replace the next condenser assembly and re-test it according to the above steps.
[0069] Step f, when the condenser assembly tested in step e becomes a qualified product three times, the solenoid valve 120 is powered off, and the valve stem 121 is reset, that is, the valve cover 140 rotates downward and contacts the top of the pressure probe 700 again;
[0070] Step g, the motor controls the pressure probe 700 to move downward to reset, so that the top of the pressure probe 700 returns to the initial position a. During this process, the valve cover 140 also rotates downward to return to the original position;
[0071] When the top of the pressure probe 700 is located at the initial position a, the force f4 at this time is detected by the pressure probe 700. If the magnitude of f4 is zero, the condenser assembly is a qualified product, that is, the processed and produced condenser assembly meets the high quality requirements; if the magnitude of f3 is not zero, the condenser assembly is an unqualified product.
[0072] When the condenser assembly fails to meet the requirements, stop testing it, replace the next condenser assembly and re-test it according to the above steps.
[0073] By controlling the up and down rotation of the valve cover 140, the magnitude of the force applied to the pressure probe 700 is detected during the process, and the detection result is compared with the standard range or standard value at the corresponding position, so as to detect whether the valve cover 140 installed in the condenser assembly meets the requirements during use, thereby ensuring the quality of subsequent dryers. The whole process is simple to operate and highly intelligent.
[0074] In addition, by testing the valve cover 140 in multiple different positions and strictly controlling whether the test results in each process meet the requirements, the high quality requirements of the subsequent dryers can be guaranteed, and the water intake required for the dryers to perform different programs can be accurately controlled to achieve full utilization of water resources.
[0075] Example 2
[0076] The detection device for the condenser assembly of the clothes dryer of this embodiment is basically the same as that of the first embodiment, and further, combined with Figure 5 , Figure 6 and Figure 7 The pressing and positioning unit of this embodiment includes a housing 410 vertically mounted on the workbench 200, and a guide groove 411 is provided on the housing 410. The guide groove 411 of this embodiment is arranged along the height direction of the housing 410, and a rotating cylinder 420 is provided inside the housing 410 of this embodiment. Figure 7 As shown, the telescopic rod 421 of the rotary cylinder 420 is connected to the mounting rod 430 , and a pressing head 440 is installed on the mounting rod 430 , and the pressing head 440 is vertically facing the workbench 200 .
[0077] It is worth noting that the installation rod 430 of this embodiment extends from the guide slot 411 , and an avoidance slot is provided at the upper end of the guide slot 411 , so as to facilitate the subsequent rotation of the installation rod 430 .
[0078] When the condenser assembly is placed on the positioning fixture 300, the rotating cylinder 420 is started to control the telescopic rod 421, the mounting rod 430 and the pressure head 440 to rotate as a whole. When the pressure head 440 rotates to the top of the condenser assembly, it stops rotating, and the rotating cylinder 420 controls the telescopic rod 421 to move downward, that is, controls the pressure head 440 to move toward the direction of the condenser assembly, so that the pressure head 440 is pressed on the condenser assembly, thereby realizing the longitudinal positioning of the condenser assembly.
[0079] Furthermore, if Figure 7 As shown, the mounting rod 430 of this embodiment is divided into two sections, one of which is V-shaped, and the open end of the V-shaped is connected to the telescopic rod 421, and the two sides of the V-shaped are connected by a pressing rod 431; the other section of the mounting rod 430 is straight, and one end of the straight section is connected to the V-shaped section, as shown in FIG. Figure 7 As shown, a pressure head 440 is installed at the other end.
[0080] By designing the shape of the mounting rod 430 and providing a pressure rod 431 on the mounting rod 430, the pressure head 440 is pressed on the condenser assembly, and when the pressure probe 700 moves upward or the valve stem 121 moves upward, it is ensured that the condenser assembly will not move during the entire process. At the same time, the pressure rod 431 ensures the stability of the force on the pressure head 440 and the mounting rod 430, thereby ensuring the accuracy and reliability of the test results. Because during the test process, once the position of the condenser assembly changes, the test results of the entire process will also change, causing the entire test result to be inaccurate, thereby seriously affecting the quality of the product.
[0081] In addition, combined Figure 6 In this embodiment, a limit block 450 is provided in the housing 410. The limit block 450 is located below the guide groove 411 to limit the downward movement range of the mounting rod 430. Figure 7 As shown, when the telescopic rod 421 drives the mounting rod 430 to move downward and presses the condenser assembly, the mounting rod 430 contacts the limit block 450, thereby preventing the mounting rod 430 from continuing to move downward and causing damage to the condenser assembly.
[0082] like Figure 8 As shown, the propulsion positioning unit of this embodiment includes a mounting bracket 510, a cylinder 520, a connecting rod 530, and a push rod 540, wherein the mounting bracket 510 is arranged below the workbench 200, and the cross-section of the mounting bracket 510 is U-shaped, the cylinder 520 is arranged in the U-shaped cavity, and the tail end of the cylinder 520 is hinged to one side of the U-shaped mounting bracket 510, the telescopic rod of the cylinder 520 is hinged to one end of the connecting rod 530, and the other end of the connecting rod 530 is fixedly installed with a push rod 540, and the push rod 540 is installed along the horizontal direction.
[0083] It is worth noting that in this embodiment, a hole is opened at a corresponding position on the mounting bracket 510, and the connecting rod 530 passes through the hole on the mounting bracket 510, and the connecting rod 530 is hinged to the mounting bracket 510. Figure 8 In this embodiment, a hole for the connecting rod 530 to extend is provided on the workbench 200, as shown in FIG. Figure 6 As shown, when the condenser assembly is placed on the positioning fixture 300, the cylinder 520 on the positioning unit is started, and the telescopic rod at the front end of the cylinder 520 is controlled to extend and retract, thereby driving the connecting rod 530 to move. Since the connecting rod 530 is hinged to the mounting bracket 510, when the telescopic rod of the cylinder 520 drives the connecting rod 530 to move, the connecting rod 530 rotates with the hinge with the mounting bracket 510 as the rotation center, thereby driving the push rod 540 to move, and making the push rod 540 contact with the outer wall of the drawer of the condenser assembly, pressing the drawer in the condenser assembly laterally, thereby achieving the effect of fixing the drawer laterally, that is, fixing the condenser assembly laterally.
[0084] The present embodiment provides a detection method for a detection device for a condenser assembly of a clothes dryer. The detection device for a condenser assembly of the present embodiment described above is used. The basic process is the same as that of embodiment 1. Furthermore, in step b of the present embodiment, when fixing the condenser assembly, first, the positioning unit is pushed to work, and its cylinder 520 works to control the rotation of the connecting rod 530 through the telescopic rod, and the push rod 540 is controlled to contact the outer wall of the drawer in the condenser assembly, and the push rod 540 is continuously controlled to move, so as to press the drawer into the condenser assembly, thereby ensuring the position of the drawer when it is fixed, so as to facilitate the subsequent contact between the pressure probe 700 and the valve cover 140, thereby performing corresponding operations. This process realizes the lateral positioning of the condenser assembly.
[0085] Afterwards, the pressing and positioning unit works, and the rotating cylinder 420 starts to control the telescopic rod 421, the mounting rod 430 and the pressure head 440 to rotate as a whole. When the pressure head 440 rotates to the top of the condenser assembly, the rotation is stopped; the rotating cylinder 420 controls the telescopic rod 421 to move downward, that is, controls the pressure head 440 to move toward the direction of the condenser assembly, so that the pressure head 440 is pressed on the condenser assembly, thereby realizing the longitudinal positioning of the condenser assembly.

[0087] The detection device for the condenser assembly of the clothes dryer of this embodiment is basically the same as that of the second embodiment, and further, combined with Figure 5 and Figure 6 In this embodiment, a sensing probe 1 610 and a sensing probe 2 620 are vertically arranged on the workbench 200. The sensing probe 1 610 and the sensing probe 2 620 of this embodiment are arranged along the length direction of the workbench 200, and the sensing probe 1 610 and the sensing probe 2 620 pass through the workbench 200, and the top ends of the sensing probe 1 610 and the sensing probe 2 620 are located in the grooves on the positioning fixture 300. When the condenser assembly is placed on the positioning fixture 300, the top ends of the sensing probe 1 610 and the sensing probe 2 620 are in contact with the lower surface of the condenser assembly, thereby sensing that the condenser assembly has been placed, and subsequent corresponding detection operations can be performed. This process is identified by the sensing probe, which is the beginning of the detection of the entire detection equipment, without the need for human judgment, so that the mechanization and automation degree of the entire equipment is improved.
[0088] It is worth noting that, since the shape of the groove on the positioning fixture 300 matches the shape of the lower part of the condenser assembly, the shape is uneven. When the condenser assembly is placed in the groove, when the condenser assembly is not placed properly, the tops of the sensing probe 1 610 and the sensing probe 2 620 will not all contact the condenser assembly, and the subsequent corresponding detection process will not be performed. Only when the sensing probe 1 610 and the sensing probe 2 620 are in contact with the condenser assembly, can the subsequent detection process be performed.
[0089] In addition, in order to facilitate the understanding of the entire detection process, a control panel 910 and an alarm 920 are also provided on the workbench 200, wherein the control panel 910 is used to set the entire detection control program, and to display the force value of subsequent detection, and to compare the detection result with the set value or the set range. When it does not meet the requirements, the alarm 920 will sound an alarm to inform the operator that the condenser being tested is always a failed product, so that a new product is replaced for testing.
[0090] like Figure 6 As shown, a power contact 800 is provided on the workbench 200 , and the power contact 800 is used to supply power to the solenoid valve 120 , so as to facilitate the solenoid valve 120 to perform corresponding work.
[0091] A detection method of a detection device for a clothes dryer condenser assembly of this embodiment adopts the detection device for a clothes dryer condenser assembly of this embodiment, and the process is as follows:
[0092] Step a: Place the assembled condenser assembly on the positioning fixture 300, and after both the sensing probe 1 610 and the sensing probe 2 620 are in contact with the condenser assembly, the detection begins;
[0093] Step b, starting the pressing and positioning unit and the pushing and positioning unit, realizing longitudinal positioning of the condenser assembly by the pressing and positioning unit; realizing transverse positioning of the condenser assembly by the pushing and positioning unit;
[0094] Specifically: first, the positioning unit is pushed to work, and its cylinder 520 works, and the connecting rod 530 is controlled to rotate through the telescopic rod, and the push rod 540 is controlled to contact the outer wall of the drawer in the condenser assembly, and the push rod 540 is continued to be controlled to move, and the drawer is pressed into the condenser assembly to ensure the position of the drawer when it is fixed, so as to facilitate the subsequent contact between the pressure probe 700 and the valve cover 140, thereby performing corresponding operations to achieve lateral positioning of the condenser assembly.
[0095] Afterwards, the pressing and positioning unit works, and the rotating cylinder 420 starts to control the telescopic rod 421, the mounting rod 430 and the pressure head 440 to rotate as a whole. When the pressure head 440 rotates to the top of the condenser assembly, the rotation is stopped; the rotating cylinder 420 controls the telescopic rod 421 to move downward, that is, controls the pressure head 440 to move toward the direction of the condenser assembly, so that the pressure head 440 is pressed on the condenser assembly to achieve the longitudinal positioning of the condenser assembly.
[0096] When the condenser assembly is positioned, the valve cover 140 is in contact with the pressure probe 700, and the force value detected by the pressure probe 700 is zero, and the top end of the pressure probe 700 is at the initial position a;
[0097] Step c, the motor drives the pressure probe 700 to move upward, and under the action of the torsion spring 141 and the connecting shaft 143, the valve cover 140 rotates with the connecting shaft 143 as the rotation center; when the top end of the pressure probe 700 moves upward to position b, in this embodiment, the distance between position b and position a is 2 mm, the pressure probe 700 detects the force f1 at this time, and the result is displayed on the control panel 910, and the detected result is compared with the set standard range F1-F2; if the detected result is within the standard range, it is qualified, and if it is not within the standard range, it is unqualified;
[0098] When the condenser assembly is unqualified, the alarm 920 will sound an alarm, and the detection thereof will be stopped at the same time, the pressing positioning unit and the pushing positioning unit will be reset, and the operator will replace the next condenser assembly and re-detect it according to the above steps.
[0099] Step d: When the condenser assembly tested in step c becomes a qualified product, the motor continues to drive the pressure probe 700 to move upward, such as Fig. 9 As shown, when the top end of the pressure probe 700 is controlled to move to position c, in this embodiment, the distance between position c and position a is 23 mm, and the result is displayed on the control panel 910. The force f2 at this time is detected by the pressure probe 700, and the detected result is compared with the set standard range F3-F4; if the detected result is within the standard range, it is qualified, if it is not within the standard range, it is unqualified. At this time, the alarm 920 will sound an alarm, stop detecting it, clamp the positioning unit and push the positioning unit to reset, and the operator replaces the next condenser assembly and re-detects it according to the above steps.
[0100] Step e: When the condenser assembly tested in step d becomes a secondary qualified product, the energized contact 800 energizes the solenoid valve 120, so that the valve stem 121 moves upward, and the valve stem 121 pushes the outer lever 150 to rotate upward, that is, drives the valve cover 140 to rotate upward. In this process, the valve cover 140 is separated from the pressure probe 700. Fig. 9 As shown, the control valve cover 140 moves to the maximum position d, and the force f3 at this time is detected by the pressure probe 700, and the result is displayed on the control panel 910. If the size of f3 is zero, it is a qualified product for three times; if the size of f3 is not zero, it is an unqualified product, and the alarm 920 will sound an alarm, stop its detection, clamp the positioning unit and push the positioning unit to reset, and the operator replaces the next condenser assembly and re-tests it according to the above steps.
[0101] Step f, when the condenser assembly tested in step e becomes a qualified product three times, the solenoid valve 120 is powered off, and the valve stem 121 is reset, that is, the valve cover 140 rotates downward and contacts the top of the pressure probe 700 again;
[0102] Step g, the motor controls the pressure probe 700 to move downward to reset, so that the top of the pressure probe 700 returns to the initial position a. During this process, the valve cover 140 also rotates downward to return to the original position;
[0103] When the top of the pressure probe 700 is located at the initial position a, the force f4 at this time is detected by the pressure probe 700, and the result is displayed on the control panel 910. If the size of f4 is zero, the condenser assembly is a qualified product, that is, the processed and produced condenser assembly meets the high quality requirements; if the size of f3 is not zero, the condenser assembly is an unqualified product, the alarm 920 will sound an alarm, stop detecting it, tighten the positioning unit and push the positioning unit to reset, and the operator replaces the next condenser assembly and re-tests it according to the above steps.
[0104] In order to facilitate the unified treatment of unqualified products, the present embodiment provides a defective product recovery area below the workbench 200. During the entire inspection process, the operator can put the unqualified condenser assembly into the area.
[0105] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
