Description

Technical Field

[0001] The invention belongs to the technical field of automatic measurement of dehumidification capacity of a dehumidifier, and in particular relates to a dehumidifier performance detection method. Background Art

[0002] In recent years, with the improvement of living standards, people's pursuit of comfortable life has been growing, and dehumidifiers have gradually become common equipment in ordinary families. At present, most household dehumidifiers are of integrated design.

[0003] With the popularity of dehumidifiers, their energy-saving performance has also attracted widespread attention. Many countries and regions have formulated standards for dehumidifier performance or energy efficiency.

[0004] At present, the test method for dehumidification is to place the dehumidifier in an environmentally controlled test room and adjust its distance from the surrounding walls to meet the standard requirements. After the dehumidifier reaches a stable operating state, the data is recorded every 10 minutes. After recording for 7 consecutive times to meet the standard requirements, the arithmetic mean of these recorded data is taken as the calculation result, and the weight of the condensed water is collected for measurement.

[0005] However, there are some problems during this testing process:

[0006] 1. Requirements for test platform construction: Currently, most companies use enthalpy difference laboratories (operating condition laboratories) to conduct dehumidification tests, which can provide operating condition and power data collection. However, the collection of weight data requires an additional electronic scale, and most electronic scales cannot currently be directly connected to enthalpy difference software to achieve real-time data collection, so manual data recording is required;

[0007] 2. Placement of the dehumidifier: During the test, since the dehumidification capacity may be large, it is sometimes necessary to lead out the drain pipe of the dehumidifier. This requires the dehumidifier to be placed in a higher position, and there is usually no platform above the ground in the test room, so different items need to be found each time to raise the dehumidifier, which is time-consuming and inconvenient. If the dehumidifier is placed on an electronic scale as a whole, the vibration generated when the dehumidifier is working will cause the electronic scale reading to be unstable, affecting the test results. In addition, the electronic scale may be subjected to pressure for a long time, which may lead to a decrease in sensitivity due to problems such as sensor damage, mechanical structure deformation, or zero drift;

[0008] 3. Frequent manual operations affect the test environment: During the test, after the dehumidifier and electronic scale are running stably in the working laboratory, the test personnel need to enter the laboratory to record the weight. If the dehumidifier water tank is full of water during the test, the test personnel need to enter the laboratory to pour water and re-weigh, which is a cumbersome process. Frequent manual operations will lead to instability of the laboratory environment and affect the test results;

[0009] 4. High error rate caused by manual operation: Since the test requires manual operation and recording, once the experimenter misses the recording time, the test will be invalid and need to be repeated, which not only wastes the experimenter and laboratory resources, but may also affect the accuracy of the test results. Summary of the invention

[0010] The purpose of the present invention is to provide a dehumidifier performance detection method, which aims to solve the problems existing in the prior art in the dehumidifier performance detection, such as unstable electronic scale readings, unstable test environment caused by frequent manual operations, and high error rate. Through the detection method of the present invention, accurate and efficient detection of dehumidifier performance can be achieved, the tediousness and errors of manual operations can be reduced, and the detection efficiency and accuracy can be improved.

[0011] To achieve the above object, the present invention provides a dehumidifier performance detection method, which mainly comprises the following steps:

[0012] S1: Install the electronic scale and the timing lifting structure on the water tank bracket, place the external water tank on the water tank bearing plate, and ensure that the water tank bearing plate of the timing lifting structure is naturally placed on the electronic scale;

[0013] S2: Perform zero calibration on the electronic scale;

[0014] S3: Operate the timing lifting structure to ensure that the water tank carrier plate can be completely removed from the electronic scale;

[0015] S4: Use a heightening bracket to place the dehumidifier to be tested on the external water tank, and provide power to the dehumidifier to be tested;

[0016] S5: connecting an external drainage pipe between the water outlet of the dehumidifier to be tested and the external water tank, and fixing the external drainage pipe with a pipe clamp;

[0017] S6: Set the weighing time interval, and start the electronic scale, the timing lifting structure and the dehumidifier to be tested to enter the test state;

[0018] S7: The built-in instant communication module of the electronic scale will upload the weighing data to the control system in real time, and the timed lifting structure will lower the water tank bearing plate after reaching the preset weighing time to weigh the condensate water once;

[0019] S8: Repeat step S7 until the test is completed.

[0020] Furthermore, when setting the weighing time in step S6, the following formula must be satisfied:

[0021] t3 = t - t1 - t2;

[0022] Wherein: t represents the standard time required for the test, t1 is the time required for the timing lifting structure to perform a lifting action on the electronic scale, and t2 is the time required for the condensate water to start shaking and finally come to rest when the external water tank is fully loaded with condensate water and the timing lifting structure moves; t3 is the preset weighing time interval; in step S2, the stable data within the t2 time period is collected as the weighing data of the condensate water.

[0023] Furthermore, the timed lifting structure described in step S1 includes a water tank supporting plate, which is hinged to the water tank bracket through a parallel connecting rod, and a driving assembly is arranged near the water tank supporting plate, and the driving assembly is used to push the water tank supporting plate so that it can be placed on the electronic scale or removed from the electronic scale.

[0024] Furthermore, one side of the water tank bearing plate is bent downward by 90° to form a push plate, and the driving assembly includes a driving cylinder, a cylinder body of the driving cylinder is transversely arranged on the bracket, and a telescopic rod thereof is adapted to the push plate.

[0025] Furthermore, a roller connected to the end of the telescopic rod abuts against the push plate.

[0026] Furthermore, the driving cylinder is any one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder.

[0027] Furthermore, the external drainage pipe is fixed to the water tank bracket and / or the raising bracket by a pipe clamp.

[0028] Furthermore, a control panel is installed on the water tank bracket, and the control panel is equipped with a start-stop button and a timing weighing knob. The start-stop button is connected to the control circuit of the electronic scale and the timing lifting structure to control the opening and closing of these two circuits, and the timing weighing knob is connected to the control circuit of the timing lifting structure to set the weighing time interval.

[0029] Furthermore, the raising bracket and the water tank bracket adopt an integrated structure, and the dehumidifier to be tested is placed on the raising bracket via a shock-absorbing platform, and leveling feet are also installed at the bottom of the water tank bracket.

[0030] Furthermore, the raising bracket and the water tank bracket adopt a split structure, and leveling feet are respectively installed at the bottom of the two.

[0031] Compared with the prior art, the present invention has the following remarkable effects:

[0032] (1) The dehumidifier performance detection method of the present invention effectively solves the problems of large fluctuations in electronic scale readings, frequent manual operations leading to unstable test environment, and high error rates in traditional testing methods. By integrating the electronic scale with the timed lifting structure, the timed automatic weighing of condensed water is achieved, while reducing manual intervention, significantly improving the accuracy and efficiency of the test. This method is not only suitable for household dehumidifiers, but can also be widely used in the performance testing of industrial dehumidifiers, providing solid technical support for energy efficiency evaluation and quality control in the dehumidifier industry;

[0033] (2) The electronic scale with integrated instant messaging module realizes automatic data collection during the dehumidifier performance testing process, effectively avoiding the tediousness and instability of manual data recording. The electronic scale is connected to the control system through the instant messaging module, and can transmit the condensation water weight data to the control system in real time without manual reading, thus reducing human errors;

[0034] (3) The design of the external water tank makes it more convenient to collect condensed water. At the same time, the external drain pipe is connected to the external water tank to avoid frequent manual water pouring operations, reduce the interference of test personnel on the test environment, and improve the stability of the test;

[0035] (4) The timed lifting structure can automatically lift the external water tank from the electronic scale at a preset time interval to prevent the electronic scale from being under pressure for a long time and causing a decrease in sensitivity. While meeting the requirements of the experimental standards, the accuracy of the test results can be ensured as much as possible;

[0036] (5) In the timed lifting structure, the water tank bearing plate is constrained by parallel connecting rods, which is conducive to ensuring the stability of the lifting process and avoiding shaking or tilting, thereby ensuring the stability of the water tank and the water inside. The push plate, as a transmission component of the driving force, works closely with the drive cylinder to achieve rapid response and precise control of the lifting action. The roller reduces friction and loss during the lifting process, further enhancing the stability and reliability of the lifting process;

[0037] (6) The integrated or split elevated bracket design not only solves the problem of dehumidifier placement, but also improves the accuracy of the test by setting up a shock-absorbing platform or independently placing the dehumidifier to be tested, and reduces the impact of dehumidifier vibration on the electronic scale reading.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0050] Figure 1 The first embodiment of the present invention is shown: a dehumidifier performance detection method, comprising the following steps:

[0051] S1: Install the electronic scale 2 and the timing lifting structure 3 on the water tank bracket 1, place the external water tank 4 on the water tank bearing plate 301, and ensure that the water tank bearing plate 301 of the timing lifting structure 3 is naturally placed on the electronic scale 2;

[0052] S2: Perform zero calibration on electronic scale 2;

[0053] S3: controlling the timing lifting structure 3 to ensure that the water tank supporting plate 301 can be completely removed from the electronic scale 2;

[0054] S4: Use the heightening bracket 5 to place the dehumidifier 6 to be tested on the external water tank 4, and provide power to the dehumidifier 6 to be tested;

[0055] S5: connecting the external drainage pipe 7 between the water outlet of the dehumidifier 6 to be tested and the external water tank 4, and fixing the external drainage pipe 7 by using the pipe clamp 701;

[0056] S6: setting the weighing time interval, and starting the electronic scale 2, the timing lifting structure 3 and the dehumidifier 6 to be tested, so that they enter the test state;

[0057] S7: The built-in instant communication module of the electronic scale 2 will upload the weighing data to the control system in real time, and the timing lifting structure 3 will lower the water tank bearing plate 301 after reaching the preset weighing time to weigh the condensed water once;

[0058] S8: Repeat step S7 until the test is completed.

[0059] In specific implementation, when setting the weighing time in step S6, the following formula must be satisfied:

[0060] t3 = t - t1 - t2;

[0061] Wherein: t represents the standard time required for the test, t1 is the time required for the timing lifting structure 3 to perform a lifting action on the electronic scale 2, and t2 is the time required for the external water tank to be fully loaded with condensate water, accompanied by the timing lifting structure action, from the condensate water starting to shake to the final resting time; t3 is the preset weighing time interval; in step S7, the stable data in the t2 time period is collected as the weighing data of the condensate water. In order to ensure the accuracy of the weighing data, in the t2 time period, the control system closely monitors the reading changes of the electronic scale through the preset algorithm. If the reading changes fluctuate within the preset threshold range, it is regarded as stable data, and the data at this time will be recorded as a valid weighing of the condensate water. If the reading changes exceed the preset threshold, the weighing data will be regarded as invalid, the system will issue a warning, and re-execute step S7. In addition, during the entire test process, all weighing data will be stored in the database of the control system in real time for subsequent analysis and processing. In this way, the amount of condensate water generated by the dehumidifier in different time periods can be accurately obtained, so as to accurately evaluate its dehumidification performance.

[0062] like Figures 2 to 6 As shown, in the specific implementation, the timing lifting structure 3 described in step S1 includes a water tank bearing plate 301, the water tank bearing plate 301 is hinged to the water tank bracket 1 through a parallel connecting rod 302, and a driving assembly 303 is arranged near the water tank bearing plate 301, and the driving assembly 303 is used to push the water tank bearing plate 301 so that it can be placed on the electronic scale 2 or removed from the electronic scale 2. One side of the water tank bearing plate 301 is bent downward by 90° to form a push plate 3011, and the driving assembly 303 includes a driving cylinder 3031, the cylinder body of the driving cylinder 3031 is transversely arranged on the bracket, and its telescopic rod is adapted to the push plate 3011. The roller 3032 connected at the end of the telescopic rod is against the push plate 3011. As a preference, considering the smoothness of operation, the driving cylinder 3031 uses an electric cylinder. In some other embodiments, a cylinder or a hydraulic cylinder can also be used.

[0063] During use, the telescopic rod of the drive cylinder 3031 pushes the roller 3032, and the roller 3032 then presses against the push plate 3011, so that the water tank bearing plate 301 and the external water tank 4 are slowly lifted from the electronic scale 2. At this time, the external water tank 4 is separated from the electronic scale 2, which effectively avoids unnecessary external force interference on the electronic scale 2 during the detection process and ensures the accuracy of the measurement data. The condensed water generated by the dehumidifier 6 to be tested is discharged into the external water tank 4 through the water outlet. As the amount of water in the external water tank 4 gradually increases, when the preset detection time is reached, the timing lifting structure 3 is started again, and the telescopic rod of the drive cylinder 3031 is retracted. Through the action of the roller 3032 and the push plate 3011, the water tank bearing plate 301 and the external water tank 4 containing the condensed water are smoothly dropped onto the electronic scale 2. The electronic scale 2 then begins to measure the weight of the external water tank 4 and the condensed water inside it. This measurement data is accurately recorded and used for subsequent calculation of the dehumidification efficiency of the dehumidifier 6. During the entire testing process, the precise control of the timing lifting structure 3 ensures the timely separation and contact between the external water tank 4 and the electronic scale 2, effectively improving the accuracy and reliability of the test results.

[0064] from Figure 7 It can be seen that in actual application, the external drain pipe 7 is fixed to the water tank bracket 1 and / or the pad bracket 5 by a pipe clamp 701. This design not only ensures the stability of the external drain pipe 7, and prevents it from interfering with the normal discharge of condensed water due to movement or shaking during the detection process, but also facilitates the operator to adjust the position and height of the external drain pipe 7 according to actual needs, reducing the interference of the external drain pipe 7 on the weighing data caused by the external drain pipe 7 placed on the external water tank 4. In addition, the fixing method of the pipe clamp 701 is simple and easy, without the need for additional complex tools or equipment, reducing the difficulty of operation and time cost. Through reasonable layout and stable fixation, the structure of the entire detection device is more compact and stable, further improving the stability and reliability of the detection process.

[0065] See also Figure 3 and Figure 6Specifically, a control panel 101 is installed on the water tank bracket 1, and the control panel 101 is equipped with a start-stop button 102 and a timing weighing knob 103. The start-stop button 102 is connected to the control circuit of the electronic scale 2 and the timing lifting structure 3 to control the opening and closing of the two circuits, and the timing weighing knob 103 is connected to the control circuit of the timing lifting structure 3 to set the weighing time interval. This design allows the operator to easily control the detection process in real time through the control panel 101. The setting of the start-stop button 102 allows the operator to easily start or stop the entire detection process without frequently contacting the complex circuit system, which not only improves the safety of the operation, but also simplifies the operation process. At the same time, the addition of the timing weighing knob 103 allows the operator to flexibly set the weighing time interval according to actual needs, thereby realizing an accurate evaluation of the performance of the dehumidifier. In addition, the installation position of the control panel 101 is reasonable, and the operation interface is clear and intuitive, so that the operator can quickly become familiar with and master its use method, further improving the efficiency and accuracy of the detection work. Through this innovative design, the operability, practicality and intelligence level of the entire detection device have been effectively improved.

[0066] like Figure 4 and Figure 6 As shown, in this embodiment, the elevation bracket 5 and the water tank bracket 1 adopt an integrated structure, and the dehumidifier to be tested is placed on the elevation bracket 5 through a shock-absorbing platform 501, and a leveling foot is also installed at the bottom of the water tank bracket 1. This integrated structural design not only enhances the stability and load-bearing capacity of the entire device, but also simplifies the assembly process and improves the manufacturing efficiency of the device. The setting of the shock-absorbing platform 501 effectively reduces the vibration generated by the dehumidifier to be tested during operation, reduces the influence of external factors on the test results, and thus ensures the accuracy and reliability of the test data. At the same time, the installation of the leveling foot allows the operator to fine-tune the water tank bracket 1 according to the actual ground conditions to ensure that the device is in a horizontal state, further improving the detection accuracy. This detailed design reflects the high attention to the practicality and accuracy of the device, and provides users with a more convenient and efficient detection experience.

[0067] Figure 8 A second embodiment of the present invention is shown, in which the heightening bracket 5 and the water tank bracket 1 are separated and are each provided with a leveling foot at the bottom. Since there is no connection between the heightening bracket 5 and the water tank, it helps to reduce the interference of the vibration generated when the dehumidifier is running on the detection process.

[0068] In summary, the invented dehumidifier performance detection method effectively solves the problems of large fluctuations in the readings of the electronic scale 2, frequent manual operations leading to unstable test environment and high error rate in the traditional test method. By integrating the electronic scale 2 with the timed lifting structure 3, the timed automatic weighing of condensed water is realized, while reducing manual intervention, significantly improving the accuracy and efficiency of the test. This method is not only suitable for household dehumidifiers, but also can be widely used in the performance testing of industrial dehumidifiers, providing solid technical support for energy efficiency evaluation and quality control in the dehumidifier industry; by integrating the electronic scale 2 with an instant messaging module, automatic data collection is realized during the dehumidifier performance detection process, effectively avoiding the tediousness and instability of manual data recording. The electronic scale 2 is connected to the control system through the instant messaging module, and can transmit the condensed water weight data to the control system in real time without manual reading, thereby reducing human errors; the design of the external water tank 4 makes it more convenient to collect condensed water. At the same time, the external water tank 4 is connected to the external drain pipe 7 to avoid frequent manual water pouring operations, reduce the interference of test personnel on the test environment, and improve the stability of the test; the timed lifting structure 3 can automatically lift the external water tank 4 from the electronic scale 2 within a preset time interval to prevent the electronic scale 2 from being under pressure for a long time and causing a decrease in sensitivity. While meeting the requirements of the experimental standards, the accuracy of the test results is ensured as much as possible; in the timed lifting structure 3, the water tank bearing plate 301 is constrained by the parallel connecting rod 302, which is conducive to ensuring the stability during the lifting process and avoiding shaking or tilting, thereby ensuring the stability of the water tank and the water inside it. The push plate 3011, as a transmission component of the driving force, closely cooperates with the drive cylinder 3031 to achieve rapid response and precise control of the lifting action. The roller 3032 reduces friction and loss during the lifting process, further enhancing the stability and reliability of the lifting process; the integrated or split elevated bracket 5 design not only solves the problem of the placement of the dehumidifier, but also improves the accuracy of the test by setting a shock-absorbing platform 501 or independently placing the dehumidifier 6 to be tested, thereby reducing the impact of the dehumidifier vibration on the reading of the electronic scale 2.
