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 fluorine deficiency protection. Background Art

[0002] If a dehumidifier lacks refrigerant, the compressor will repeatedly operate in a cycle. For a dehumidifier without refrigerant, heat dissipation cannot be achieved through the circulation of the refrigerant. Without heat dissipation, the compressor will run idly. If the idle time is too long, a large amount of heat will accumulate. When a certain temperature is reached or it lasts for a long time, there will be a risk of the compressor catching fire or leaking electricity, which poses a great safety hazard. At the least, the machine will be burned out, at the worst, it may damage related property such as the consumer's house, and even more seriously, it may pose a risk to personal safety.

[0003] In the prior art, some dehumidifiers have no protection against lack of refrigerant, or simply judge whether the dehumidifier leaks refrigerant by the difference between the ambient temperature and the temperature of the exhaust pipe. Dehumidifiers without refrigerant deficiency judgment have great safety hazards, while products with refrigerant deficiency protection judged by the simple difference between the ambient temperature and the temperature of the exhaust pipe have a high possibility of misjudgment, resulting in problems such as reporting refrigerant deficiency protection when there is no refrigerant deficiency or not protecting and reporting faults when there is a real refrigerant deficiency.

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

[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. Apparently, 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 scope of protection of the present invention.

[0050] The first implementation manner:

[0051] The first implementation manner of the present invention provides a control method for fluorine-deficiency protection, including: starting the compressor working timer when the compressor is in the working state; obtaining the ambient humidity of the dehumidifier in real time through a humidity sensor; determining whether the ambient humidity meets a first preset condition; in response to the ambient humidity meeting the first preset condition, obtaining the ambient temperature of the dehumidifier in real time through a first temperature sensor; determining whether the ambient temperature meets a second preset condition or whether the ambient humidity and ambient temperature meet a third preset condition; in response to the ambient temperature meeting the second preset condition or the ambient humidity and ambient temperature meeting the third preset condition, obtaining the continuous running time and the sustained running time of the compressor, and determining whether the continuous running time and the sustained running time of the compressor meet a fourth preset condition; in response to the continuous running time and the sustained running time of the compressor meeting the fourth preset condition, obtaining the coil temperature of the dehumidifier in real time through a second temperature sensor; determining whether the difference between the ambient temperature and the coil temperature meets a fifth preset condition; in response to the difference between the ambient humidity and the coil temperature meeting the fifth preset condition, controlling the dehumidifier to perform fluorine-deficiency protection. The control method for fluorine-deficiency protection of the present invention integrates multiple key parameters such as humidity, temperature, compressor running time, and coil temperature for judgment, greatly reducing the misjudgment that may be caused by single-parameter judgment and improving the accuracy of judging whether the dehumidifier is fluorine-deficient; as the ambient temperature and humidity change in real time, the system automatically detects and judges according to the set logic, timely adjusts the operating state of the device or triggers the fluorine-deficiency protection mechanism, and relevant preset conditions such as humidity thresholds and temperature thresholds in the first to fifth preset conditions can be adjusted according to different dehumidifier models, usage environments, and user requirements, improving the versatility and adaptability of the product.

[0052] The implementation details of the control method for fluorine-deficiency protection in this implementation manner 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 implementation manner is as Figure 1 shown. This implementation manner is applied to a control system for fluorine-deficiency protection.

[0053] Step S1, start the compressor working timer when the compressor is in the working state.

[0054] Specifically, by setting a dedicated timer chip inside the dehumidifier and associating the timer chip with the power supply line or control line of the compressor, when the compressor is powered on and starts working, the timer chip is triggered to start timing. Once the compressor stops working, in a way that the control signal is switched to the stop state, the timer chip pauses timing and records the duration data of this operation.

[0055] Step S2: Obtain the ambient humidity of the dehumidifier in real time through a humidity sensor.

[0056] Specifically, the humidity sensor is installed at a relatively open position on the outer side of the body, so as to avoid interference from processes such as internal heat exchange of the dehumidifier to the humidity sensor, ensure that the measured humidity is the real ambient humidity, help to master the humidity situation from the overall environmental perspective, and at the same time facilitate the user to intuitively understand the actual humidity level of the environment where they are. Thus, the ambient humidity H of the dehumidifier can be obtained through the humidity sensor. r , with the unit of %RH.

[0057] Step S3: Determine whether the ambient humidity meets the first preset condition.

[0058] Specifically, the first preset condition is that the ambient humidity is less than or equal to the first humidity threshold. Among them, the first humidity threshold is preset as N, that is, the first preset condition is that the ambient humidity ≤ N. The first humidity threshold is a preset value, and relevant technical personnel can adjust the specific value of the first humidity threshold based on actual needs during the actual application process.

[0059] Step S4: In response to the ambient humidity meeting the first preset condition, obtain the ambient temperature of the dehumidifier in real time through the first temperature sensor;

[0060] Specifically, the first temperature sensor is installed at a relatively open position on the outer side of 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 ambient temperature, facilitate accurately mastering the temperature state of the entire usage environment, and thus the ambient temperature T of the dehumidifier can be obtained through the first temperature sensor. r , with the unit of °C.

[0061] Step S5: Determine whether the ambient temperature meets the second preset condition or whether the ambient humidity and ambient temperature meet the third preset condition.

[0062] Specifically, as Figure 2 shown, the second preset condition is that the ambient temperature is less than or equal to the first temperature threshold. Among them, the first temperature threshold is preset as M, that is, the second preset condition is that the ambient temperature ≤ M. The first temperature threshold is a preset value, and relevant technical personnel can adjust the specific value of the first temperature threshold based on actual needs during the actual application process.

[0063] The third preset condition is that the environmental humidity threshold is that the environmental humidity is less than or equal to the first dynamic humidity threshold obtained based on the environmental temperature; and the environmental temperature is greater than the first temperature threshold and less than or equal to the second temperature threshold.

[0064] Among them, the first temperature threshold is M, the second temperature threshold is S, and S > M. The second temperature threshold is a preset value, and relevant technical personnel can adjust the specific value of the second temperature threshold based on actual needs during actual application.

[0065] The third preset condition is: H rx ≤T H0 -(T r -T0)×A and M < T r ≤S.

[0066] In the formula, H rx is the environmental temperature measured in real time, T r is the environmental temperature measured in real time, A is a preset fixed humidity parameter value, and A is a positive number, T H0 is a preset value, and T is obtained according to the first humidity threshold H0 = N - A, T0 is a preset value, and T0 = M + 1 is obtained according to the first temperature threshold, M is the first temperature threshold, S is the second temperature threshold, and S > M.

[0067] It should be noted that no specific limit is placed on the specific value of A here, and relevant technical personnel can change the specific value of A based on actual needs.

[0068] Furthermore, through the setting of the third preset condition, the determination range of the lack of refrigerant protection is expanded. Since there is a close relationship between the environmental temperature and the saturated moisture content of the air, when the temperature is different, the appropriate humidity range corresponding to ensuring the reasonable operation of the dehumidifier is also different. The first dynamic humidity threshold obtained based on the environmental temperature is adopted in the third preset condition. Therefore, the determination standard of humidity is not fixed, but will change with the change of the environmental temperature. By judging whether the environmental temperature and humidity meet the third preset condition, it is possible to more accurately understand the environmental state of the dehumidifier, and then more accurately judge whether the compressor lacks refrigerant, and thus can effectively reduce misjudgments caused by fluctuations in environmental factors, improve the accuracy and reliability of judging the lack of refrigerant in the compressor, and thus better guide the repair and maintenance work.

[0069] Step S6, in response to the environmental temperature satisfying the second preset condition or the environmental humidity and environmental temperature satisfying the third preset condition, obtain the continuous operation time and the continuous running time of the compressor, and judge whether the continuous operation time and the continuous running time of the compressor meet the fourth preset condition.

[0070] Specifically, the continuous operation time of the compressor refers to the duration during which the compressor operates without interruption. The total operation time of the compressor refers to the total duration of operation of the compressor within one working cycle.

[0071] The fourth preset condition is that the continuous operation time of the compressor is greater than or equal to the first time threshold and less than the second time threshold, and the total operation time of the compressor is greater than the third time threshold.

[0072] Among them, the first time threshold is T1, the second time threshold is T2, the third time threshold is T3, and T1 < T2 < T3. The first time threshold, the second time threshold, and the third time threshold are preset values.

[0073] As an example, the first time threshold is 1 min, the second time threshold is 3 min, and the third time threshold is 10 min. Relevant technical personnel can adjust the specific values of the first time threshold, the second time threshold, and the third time threshold based on actual needs during actual application.

[0074] The fourth preset condition is: T1 ≤ T L < T2 and T Q > T3.

[0075] In the formula, T L is the continuous operation time of the compressor, T Q is the total operation time of the compressor, T1 is the first time threshold, T2 is the second time threshold, T3 is the third time threshold, and T1 < T2 < T3.

[0076] Step S7, in response to the continuous operation time and the total operation time of the compressor satisfying the fourth preset condition, the coil temperature of the dehumidifier is obtained in real time through the second temperature sensor.

[0077] Specifically, the second temperature sensor is installed on the surface of the evaporator coil, and a position with better air circulation is preferably selected, so as to accurately measure the coil temperature after air heat exchange. Thus, the coil temperature T p of the dehumidifier can be obtained through the second temperature sensor, and the unit is °C.

[0078] As an example, the second temperature sensor is installed in the middle or at the outlet of the coil to obtain representative temperature data. Avoid installing it at the dead ends or blocked positions of the coil to avoid measuring inaccurate temperatures.

[0079] Step S8, determine whether the difference between the ambient temperature and the coil temperature satisfies the fifth preset condition.

[0080] Specifically, the fifth preset condition is that the difference between the ambient temperature and the coil temperature is less than or equal to a third temperature threshold. Here, the third temperature threshold is R, where R is a fixed positive integer in °C. The third temperature threshold is a preset value, and relevant technicians can adjust the specific value of the third temperature threshold based on actual requirements during actual application.

[0081] The fifth preset condition is: T r -T p ≤R.

[0082] In the formula, T r is the ambient temperature of the dehumidifier, T p is the coil temperature of the dehumidifier, and R is the third temperature threshold, where R is a fixed positive integer.

[0083] Step S9, in response to the difference between the ambient humidity and the coil temperature satisfying the fifth preset condition, control the dehumidifier to perform underfluorine protection.

[0084] Specifically, when the dehumidifier simultaneously satisfies the above first preset condition, second preset condition, fourth preset condition, and fifth preset condition, or when the dehumidifier simultaneously satisfies the above first preset condition, third preset condition, fourth preset condition, and fifth preset condition, at this time, control the dehumidifier to perform underfluorine protection.

[0085] Controlling the dehumidifier to perform underfluorine protection includes: sending the corresponding fault code to the display screen driving circuit. The display screen can be a liquid crystal display screen or a light-emitting diode display screen. Control the dehumidifier to, through the display chip of the display screen, display a specific code representing underfluorine or lack of refrigerant on the screen according to the preset fault code display rule; and reduce the operating frequency of the compressor or even temporarily stop the operation of the compressor to prevent the compressor from being damaged due to overwork in the underfluorine state.

[0086] The control method for fluorine-deficiency protection provided by the first embodiment of the present invention includes: starting the compressor operation timing when the compressor is in the working state; obtaining the ambient humidity of the dehumidifier in real time through a humidity sensor; determining whether the ambient humidity meets a first preset condition; in response to the ambient humidity meeting the first preset condition, obtaining the ambient temperature of the dehumidifier in real time through a first temperature sensor; determining whether the ambient temperature meets a second preset condition or whether the ambient humidity and the ambient temperature meet a third preset condition; in response to the ambient temperature meeting the second preset condition or the ambient humidity and the ambient temperature meeting the third preset condition, obtaining the continuous operation time and the sustained operation time of the compressor, and determining whether the continuous operation time and the sustained operation time of the compressor meet a fourth preset condition; in response to the continuous operation time and the sustained operation time of the compressor meeting the fourth preset condition, obtaining the coil temperature of the dehumidifier in real time through a second temperature sensor; determining whether the difference between the ambient temperature and the coil temperature meets a fifth preset condition; in response to the difference between the ambient humidity and the coil temperature meeting the fifth preset condition, controlling the dehumidifier to perform fluorine-deficiency protection. The control method for fluorine-deficiency protection of the present invention integrates multiple key parameters such as humidity, temperature, compressor operation time, and coil temperature for judgment; ambient humidity is an important factor affecting the operation and dehumidification effect of the dehumidifier, and the demand and performance for the refrigerant amount are different in different humidity environments; ambient temperature not only affects the moisture content of the air, but also has a significant impact on the working efficiency of the compressor and the state of the refrigerant. Through the comprehensive judgment of these two, the working conditions of the dehumidifier can be more comprehensively understood; the continuous operation time and the sustained operation time of the compressor reflect the working intensity and stability of the equipment; if the compressor operation time is abnormal, it may imply problems such as refrigerant leakage, resulting in it always being in the working state to make up for insufficient refrigeration or dehumidification. Incorporating it into the judgment system can assist in judging whether there is a lack of fluorine from the perspective of the equipment operation state; the difference between the coil temperature and the ambient temperature is directly related to the state of the refrigerant; normally, the refrigerant circulates in the coil to achieve heat exchange, making the coil temperature and the ambient temperature have a reasonable temperature difference range. If this difference deviates from the normal range, it is very likely due to insufficient refrigerant amount resulting in a change in refrigeration capacity; through the comprehensive judgment of these multi-dimensional parameters, the misjudgment caused by single-parameter judgment is greatly reduced, and the accuracy of judging whether the dehumidifier lacks fluorine is improved; and the relevant preset conditions such as the humidity threshold and temperature threshold in the first to fifth preset conditions can be adjusted according to different dehumidifier models, usage environments, and user requirements, improving the versatility and adaptability of the product.

[0087] The step divisions of the above various methods are 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 relationships are included, they are all within the protection scope of this patent. Making insignificant modifications to the algorithm or process or introducing insignificant designs, but without changing the core design of the algorithm and process, are all within the protection scope of this patent.
