Description

Technical Field

[0001] The present invention relates to the technical field of dehumidifiers, and particularly to a control method, a control system and a dehumidifier for high-temperature protection. Background Art

[0002] In the current dehumidifier market, the high-temperature protection control logic generally adopts the method of setting a fixed temperature protection point. For example, specific temperature values such as 36°C and 40°C are set. Once the detected ambient temperature is higher than these preset values, the high-temperature protection mechanism is activated. Due to the differences in the characteristics of different dehumidifier products, the actual tripping temperature points are different. This is because the high-temperature protection point of the product does not depend solely on a single factor of the ambient temperature, and the ambient humidity also plays a key role. In fact, humidity has an important impact on the operation of the dehumidifier. At a relatively high ambient temperature, if the humidity is low, the dehumidifier may still operate normally; while at a relatively low ambient temperature, if the humidity is high, the dehumidifier may also trip.

[0003] Since each dehumidifier product has unique performance characteristics, it is unreasonable and inaccurate to simply rely on a fixed ambient temperature point to determine whether to perform high-temperature protection, making it difficult to balance the safety of the product and the user experience of consumers, and unable to meet the diverse and refined requirements of the market for high-temperature protection control of dehumidifiers.

[0004] Therefore, it is necessary to provide a new control method, a control system and a dehumidifier for high-temperature protection. Summary of the Invention

[0005] Based on the above problems existing in the prior art, the purpose of the embodiments of the present invention is to provide a control method, a control system and a dehumidifier for high-temperature protection, which ensure the safe and stable operation of the equipment and improve the reliability and service life of use.

[0006] To achieve the above purpose, on the one hand, the present invention provides a control method for high-temperature protection, including:

[0019] Further, in S5, the obtaining of the operation time of the dehumidifier includes: by setting a dedicated timer chip inside the dehumidifier, associating the timer chip with the power supply line or control line of the compressor. When the compressor of the dehumidifier is powered on and starts working, it triggers the timer chip to start timing. Once the compressor stops working, in the way of switching to the stop state through a control signal, the timer chip pauses timing and records the duration data of this operation.

[0020] Further, in S6, the second preset condition is that the number of circulation periods within the operation interval is less than or equal to the preset number of periods. Wherein, the preset number of periods is X, that is, the second preset condition is that the number of circulation periods within the operation interval ≤ X.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0050] The first embodiment:

[0051] The first embodiment of the present invention provides a control method for high-temperature protection, including: obtaining the first environmental temperature and the first environmental humidity of the dehumidifier through a first temperature sensor and a humidity sensor respectively; obtaining the continuous coil temperature data of the dehumidifier in the operation interval in real time through a second temperature sensor; dividing a cycle period according to the continuous coil temperature data in the operation interval; judging whether the coil temperature data in the cycle period satisfies a first preset condition; in response to the coil temperature data in the cycle period satisfying the first preset condition, obtaining the operation time of the dehumidifier; judging whether the number of cycle periods in the operation interval satisfies a second preset condition and judging whether the operation time of the dehumidifier satisfies a third preset condition; in response to the number of cycle periods in the operation interval satisfying the second preset condition and the operation time of the dehumidifier satisfying the third preset condition, controlling the dehumidifier to perform high-temperature protection; in response to the dehumidifier performing high-temperature protection, recording the high-temperature protection duration; when the high-temperature protection duration reaches a preset duration, obtaining the second environmental temperature and the second environmental humidity of the dehumidifier through the first temperature sensor and the humidity sensor respectively; judging whether the second environmental humidity satisfies a fifth preset condition based on the first environmental temperature, the first environmental humidity, and the second environmental temperature. If the second environmental humidity satisfies the fifth preset condition, restart the dehumidifier and return to the initial step; if not, continue with the high-temperature protection. The control method for high-temperature protection of the present invention can effectively monitor the operation of the dehumidifier, prevent it from being damaged under abnormal working conditions such as high temperature, ensure the safe and stable operation of the equipment, and improve the use reliability and service life by obtaining data through multiple sensors, judging the operation state based on conditions such as coil temperature, and implementing high-temperature protection and restart mechanisms.

[0052] The implementation details of the high-temperature protection control method in this embodiment will be specifically described below. The following content is only the implementation details provided for convenient understanding and is not necessary for implementing this solution. The specific process of this embodiment is as Figure 1 shown, and this embodiment is applied to the high-temperature protection control system.

[0053] Step S1, obtain the first ambient temperature and the first ambient humidity of the dehumidifier through the first temperature sensor and the humidity sensor respectively.

[0054] Specifically, install the first temperature sensor at a relatively open position outside the body that can represent the ambient temperature, so as to avoid interference from the internal heating components of the dehumidifier to the temperature measurement, ensure that the obtained is the real external ambient temperature, facilitate accurately grasping the temperature state of the entire usage environment, and thus the first ambient temperature T of the dehumidifier can be obtained through the first temperature sensor m , with the unit of °C.

[0055] Install the humidity sensor at a relatively open position outside the body, so as to avoid interference from the internal heat exchange process of the dehumidifier to the humidity sensor, ensure that the measured humidity is the real external ambient humidity, help to grasp the humidity situation from the perspective of the overall environment, and at the same time facilitate users to intuitively understand the actual humidity level of the environment where they are located. Thus, the first ambient humidity H of the dehumidifier can be obtained through the humidity sensor m , with the unit of %RH.

[0056] Step S2, continuously obtain the coil temperature data of the dehumidifier in the operating interval in real time through the second temperature sensor.

[0057] Specifically, install the second temperature sensor on the surface of the evaporator coil, and try to select a position with better air circulation, so as to accurately measure the coil temperature after air heat exchange; thus, the coil temperature T of the dehumidifier can be obtained through the second temperature sensor p , with the unit of °C. As Figure 2 shown, use a data recorder to continuously receive the coil temperature T of the dehumidifier collected by the second temperature sensor at a set frequency p , and then obtain the continuous coil temperature T of the dehumidifier in the operating interval in real time p data, and display it in the form of a line chart.

[0058] Step S3, divide the cycle period according to the continuous coil temperature data in the operating interval.

[0059] Specifically, as Figure 2 shown, dividing the cycle period according to the continuous coil temperature data in the operating interval includes: according to the coil temperature T pis divided according to the change characteristics. A complete cycle is determined according to the specific change pattern of the pipe temperature T p of. A complete cycle includes the coil temperature T p descent stage, the coil temperature T p rise stage and the coil temperature T p rises to the maximum value.

[0060] As an example, during the descent stage of the coil temperature T p The cycle starts at the moment when the coil temperature T p starts to decline, that is, when the coil temperature T p begins to decrease, it is regarded as the start of a new cycle; the coil temperature T p rise stage. After the coil temperature T p declines, there will then be a process of the coil temperature T p rising; when the coil temperature T p rises to the maximum value: this rising process continues until the coil temperature T p reaches the maximum value. When the coil temperature T p rises to the highest value, a complete cycle ends.

[0061] Furthermore, as Figure 3 shown, the duration of the cycle is greater than or equal to the first preset duration. That is to say, the entire time length from when the coil temperature T p starts to decline until the coil temperature T p rises to the maximum value constitutes a complete cycle. And there is a lower limit requirement for the duration of this cycle, that is, the time of the entire cycle cannot be less than the first preset duration. That is to say, if the temperature drops and then rises quickly, and the entire process is less than the first preset duration, then this cannot be regarded as a complete cycle. Among them, the first preset duration is a preset value, and relevant technical personnel can adjust the specific value of the first preset duration based on the gear of the dehumidifier during actual application.

[0062] As an example, the first preset duration is 1 minute. That is to say, the pipe temperature T p first drops and then rises, and the entire cycle from the start of the drop to the rise to the maximum value is not less than 1 minute.

[0063] Step S4, determine whether the coil temperature data within the cycle satisfies the first preset condition.

[0064] Specifically, the first preset condition is that the coil temperature T within the cycle pThe data are all greater than the first temperature threshold, and the difference between the maximum value and the minimum value of the coil temperature within the same cycle is greater than or equal to the second temperature threshold. Among them, the first temperature threshold is preset to M, the second temperature threshold is preset to N, the maximum value of the coil temperature within the same cycle is T pmax , and the minimum value of the coil temperature within the same cycle is T pmin , that is, the first preset condition is: all coil temperatures T within the cycle p > M, and T pmax -T pmin ≥ N. The first humidity threshold and the second temperature threshold are preset values, and relevant technicians can adjust the specific values of the first humidity threshold and the second temperature threshold based on the gear of the dehumidifier during actual application.

[0065] As an example, the first temperature threshold is preset to 0 °C, and the second temperature threshold is preset to 3 °C.

[0066] Step S5, in response to the coil temperature data within the cycle satisfying the first preset condition, obtain the operating time of the dehumidifier.

[0067] Specifically, the obtaining of the operating time of the dehumidifier includes: by setting a dedicated timer chip in the dehumidifier, associating the timer chip with the power supply line or the control line of the compressor, when the compressor of the dehumidifier is powered on and starts to work, triggering the timer chip to start timing, and once the compressor stops working, by means of switching the control signal to the stop state, making the timer chip pause timing and recording the duration data of this operation.

[0068] Step S6, determine whether the number of cycles within the operating interval satisfies the second preset condition and determine whether the operating time of the dehumidifier satisfies the third preset condition.

[0069] Specifically, according to the cycles divided in step S2, obtain the number of cycles within the operating interval. The second preset condition is that the number of cycles within the operating interval is less than or equal to the preset number of cycles. Among them, the preset number of cycles is X, that is, the second preset condition is that the number of cycles within the operating interval ≤ X. The preset number of cycles is a preset value, and relevant technicians can adjust the specific value of the preset number of cycles based on the gear of the dehumidifier during actual application.

[0070] As an example, the first preset number of cycles is 3.

[0071] The third preset condition is that the operating time is greater than or equal to the second preset duration Y, that is, the third preset condition is that the operating time ≥ Y. The second preset duration is a preset value, and relevant technicians can adjust the specific value of the second preset duration based on the gear of the dehumidifier during actual application.

[0072] As an example, the second preset duration is 4.5 h.

[0073] Step S7, in response to the number of cycle periods within the operating interval satisfying the second preset condition and the operating time of the dehumidifier satisfying the third preset condition, control the dehumidifier to perform high-temperature protection.

[0074] Specifically, the control of the dehumidifier to perform high-temperature protection includes that the control unit inside the dehumidifier will immediately execute the control logic to turn off the output of the compressor, that is, the compressor stops working and no longer performs the refrigeration cycle. After the compressor stops working, the heat generated by it will gradually decrease, thereby preventing the compressor from being damaged due to overheating.

[0075] Furthermore, in addition to turning off the compressor, the control system of the dehumidifier may also operate on other related components. As an example, the fan may continue to run to help with heat dissipation. The continuous operation of the fan can accelerate air flow, dissipate the heat around the compressor and the exhaust pipe, and reduce the temperature of the dehumidifier.

[0076] Step S8, in response to the dehumidifier performing high-temperature protection, obtain the high-temperature protection duration.

[0077] Specifically, the obtaining of the high-temperature protection duration includes that the control system of the dehumidifier uses a timer set inside to start timing from the start of performing high-temperature protection, and thus obtains the high-temperature protection duration.

[0078] Step S9, when the high-temperature protection duration reaches the fourth preset condition, obtain the second ambient temperature and the second ambient humidity of the dehumidifier through the first temperature sensor and the humidity sensor respectively.

[0079] Specifically, the fourth preset condition is that the high-temperature protection duration is greater than the third preset duration Z, that is, the third preset condition is that the high-temperature protection duration > Z. The third preset duration is a preset value, and relevant technical personnel can adjust the specific value of the third preset duration based on the gear of the dehumidifier during actual application.

[0080] When the high-temperature protection duration is greater than the third preset duration Z, the first temperature sensor measures the ambient temperature at this time, and this temperature value is called the second ambient temperature T n . As an example, if the dehumidifier is operating indoors, when the high-temperature protection duration is greater than the third preset duration Z, the first temperature sensor will detect the indoor temperature at that time, such as 28 °C, and this 28 °C is the second ambient temperature. The humidity sensor measures the ambient humidity when the high-temperature protection duration is greater than the third preset duration Z, and this humidity value is called the second ambient humidity H n. As an example, when the humidity sensor detects that the indoor humidity is 60% when the high-temperature protection duration is greater than the third preset duration Z, then 60% is the second environmental humidity value.

[0081] Step S10, based on the first environmental temperature, the first environmental humidity, and the second environmental temperature, determine whether the second environmental humidity meets the fifth preset condition. If the second environmental humidity meets the fifth preset condition, restart the dehumidifier and return to step S1; if not, continue with high-temperature protection.

[0082] Specifically, the fifth preset condition is that the second environmental humidity is less than the dynamic humidity threshold obtained based on the first environmental temperature, the first environmental humidity, and the second environmental temperature;

[0083] The fifth preset condition is: H n <H m +(T m -T n )*5%

[0084] Wherein, H n is the second environmental humidity, H m is the first environmental humidity, T m is the first environmental temperature, T n is the second environmental temperature.

[0085] Specifically, in the high-temperature protection control mechanism of the dehumidifier, there is an initial jump temperature point A determined by specific conditions and a fixed slope of -5. Based on these two key elements, a straight-line equation with specific significance can be constructed. When the dehumidifier is running, continuously monitor the environmental temperature and humidity, and substitute them into the fifth preset condition: H n <H m +(T m -T n )*5% for judgment. If the fifth preset condition is met, it means that the current temperature and humidity conditions are below the straight line, and the dehumidifier can continue to work normally. In the actual operation scenario, after the dehumidifier starts working, the system continuously monitors various parameters. Assume that initially, at a certain combination of environmental temperature and humidity, the calculated point is below the straight line, and the dehumidifier runs normally. As the environmental temperature gradually rises or the humidity changes, if the new temperature and humidity combination still satisfies the fifth preset condition, the dehumidifier continues to run. But when it is found during a certain monitoring that the new parameters substituted do not satisfy the inequality, that is, when it is above the straight line, the high-temperature protection mechanism will be triggered at this time, and the current environmental state will be recorded. After that, the system will re-adjust the calculation according to the new environmental data. This process is like continuously calibrating a boundary line. After multiple such adjustments and re-calculations, a stable critical point will finally be found, and the straight line corresponding to this critical point Figure 4The red line. After determining this critical point, as long as the operating parameters of the dehumidifier remain below the range defined by this red line, stable operation in a high-temperature environment can be ensured, avoiding frequent tripping due to high temperature and affecting customer use, while also ensuring the safety of the product and preventing safety issues caused by overheating of components such as compressors, thereby enhancing customer satisfaction.

[0086] The control method for high-temperature protection provided by the first embodiment of the present invention includes: obtaining the first ambient temperature and the first ambient humidity of the dehumidifier through a first temperature sensor and a humidity sensor respectively; obtaining continuous coil temperature data of the dehumidifier within the operating range in real time through a second temperature sensor; dividing a cycle period according to the continuous coil temperature data within the operating range; determining whether the coil temperature data within the cycle period meets a first preset condition; in response to the coil temperature data within the cycle period meeting the first preset condition, obtaining the operating time of the dehumidifier; determining whether the number of cycle periods within the operating range meets a second preset condition and determining whether the operating time of the dehumidifier meets a third preset condition; in response to the number of cycle periods within the operating range meeting the second preset condition and the operating time of the dehumidifier meeting the third preset condition, controlling the dehumidifier to perform high-temperature protection; in response to the dehumidifier performing high-temperature protection, recording the high-temperature protection duration; when the high-temperature protection duration reaches a preset duration, obtaining the second ambient temperature and the second ambient humidity of the dehumidifier through the first temperature sensor and the humidity sensor respectively; determining whether the second ambient humidity meets a fifth preset condition based on the first ambient temperature, the first ambient humidity, and the second ambient temperature. If the second ambient humidity meets the fifth preset condition, restart the dehumidifier and return to the initial step; if not, continue with high-temperature protection. The present invention divides the cycle period according to the change characteristics of the coil temperature and sets a lower limit for the cycle period duration, making the judgment of the operating state of the dehumidifier more scientific and reasonable; by determining whether the coil temperature data within the cycle period meets the preset condition and whether the number of cycle periods and the operating time within the operating range meet the standards, the working state of the dehumidifier can be comprehensively and accurately evaluated, effectively preventing the equipment from being damaged due to long-term high-intensity operation; when the high-temperature protection condition is met, the compressor is timely shut down and auxiliary heat dissipation measures are taken to prevent the compressor from overheating and being damaged, extending the service life of the equipment; after the high-temperature protection duration reaches a certain condition, the ambient temperature and humidity are detected again, and it is determined whether to restart the dehumidifier based on the dynamic humidity threshold, realizing the intelligent control of the equipment, ensuring the safety of the equipment and enabling it to resume operation under suitable environmental conditions, improving the use efficiency and intelligence level of the dehumidifier, and at the same time avoiding unnecessary energy consumption.

[0087] The step division of the above various methods is only for clear description. When implemented, they can be combined into one step or some steps can be split into multiple steps. As long as the same logical relationship is included, it is within the protection scope of this patent; adding insignificant modifications to the algorithm or process or introducing insignificant designs, but without changing the core design of the algorithm and process, is within the protection scope of this patent.

[0088] Second Embodiment:

[0089] As Figure 5 shown, the second embodiment of the present invention provides a control system for high-temperature protection. The system includes: a first ambient temperature and humidity acquisition module 201, a coil temperature acquisition module 202, a cycle period division module 203, a first judgment module 204, an operation time acquisition module 205, a second judgment module 206, a high-temperature protection control module 207, a high-temperature protection duration acquisition module 208, a second ambient temperature and humidity acquisition module 209, and a third judgment module 210.
