Description

Technical Field

[0001] This invention relates to the field of dehumidifier control, and in particular to a control method and system for a dehumidifier. Background Technology

[0002] The working principle of a dehumidifier is that indoor air enters through the air inlet area driven by a fan, first passes through the evaporator to cool down and produce condensate, and then the dried air passes through the condenser to cool it down before being discharged through the air outlet. Therefore, according to the principle of energy conservation, the temperature of the air blown out by the dehumidifier will always be higher than the ambient temperature. In a high-temperature and high-humidity environment, although it can dehumidify, the excessively high outlet air temperature can also cause discomfort to the user. Summary of the Invention

[0003] One objective of this invention is to provide a control method for a dehumidifier to solve the problem of excessively high air outlet temperature in existing dehumidifiers, which leads to a poor user experience.

[0004] A further objective of this invention is to enable the evaporator to operate selectively, thereby improving the efficiency of the dehumidifier evaporator.

[0005] Specifically, the present invention provides a control method for a dehumidifier, the dehumidifier including an evaporator having a first flow pipe and a second flow pipe with a length shorter than the first flow pipe, the control method comprising the following steps:

[0006] Obtain the current ambient humidity.

[0007] Subtract the first ambient humidity from the preset humidity to obtain the first humidity difference value;

[0008] The first flow line and / or the second flow line of the evaporator are selectively opened according to the magnitude of the first humidity difference.

[0009] Further, selectively opening the first flow pipe and / or the second flow pipe of the evaporator according to the magnitude of the first humidity difference includes the following steps:

[0010] When the first humidity difference is greater than the first preset humidity value and less than or equal to the second preset humidity value, only the first flow pipeline is opened.

[0011] Furthermore, after opening only the first flow pipe when the first humidity difference is greater than the first preset humidity value and less than or equal to the second preset humidity value, the method further includes the following steps:

[0012] Obtain the second ambient humidity after a first preset time has elapsed since the first flow pipeline was opened;

[0013] Subtract the second ambient humidity from the preset humidity to obtain the second humidity difference value;

[0014] Determine whether the second humidity difference is less than or equal to the first preset humidity value. If so, only the second flow pipe is opened; otherwise, only the first flow pipe is opened.

[0015] Further, selectively opening the first flow pipe and / or the second flow pipe of the evaporator according to the magnitude of the first humidity difference includes the following steps:

[0016] When the first humidity difference is greater than the second preset temperature value, the first flow pipeline and the second flow pipeline are opened simultaneously.

[0017] Furthermore, after simultaneously opening the first flow pipe and the second flow pipe when the first humidity difference is greater than the second preset temperature value, the method further includes the following steps:

[0018] Obtain the third ambient humidity after a second preset time has elapsed since the first and second flow pipelines were simultaneously opened.

[0019] Subtract the third ambient humidity from the preset humidity to obtain the third humidity difference value;

[0020] Determine whether the third humidity difference is greater than the first preset humidity value and less than or equal to the second preset humidity value. If so, only the first flow pipe is opened; otherwise, both the first flow pipe and the second flow pipe are opened simultaneously.

[0021] Further, selectively opening the first flow pipe and / or the second flow pipe of the evaporator according to the magnitude of the first humidity difference includes the following steps:

[0022] When the first humidity difference is less than or equal to the first preset humidity value, only the second flow pipeline is opened.

[0023] Furthermore, it also includes the following steps:

[0024] Obtain the current ambient temperature and the temperature around the first human body;

[0025] The second ambient temperature of the human body is obtained when the ambient temperature is greater than the first preset temperature and the second humidity difference is greater than the first preset humidity value and less than or equal to the second preset humidity value.

[0026] Determine whether the temperature difference between the ambient temperature of the first human body and the ambient temperature of the second human body is greater than a second preset temperature. If so, only the second flow pipeline is opened; otherwise, the first flow pipeline continues to operate for a third preset time until the temperature difference is greater than the second preset temperature.

[0027] Furthermore, it also includes the following steps:

[0028] Obtain the current ambient temperature and the temperature around the first human body;

[0029] The third ambient temperature of the human body is obtained when the ambient temperature is greater than the first preset temperature and the second humidity difference is greater than the second preset humidity value.

[0030] Determine whether the temperature difference between the ambient temperature of the first human body and the ambient temperature of the third human body is greater than a second preset temperature. If so, only the first flow pipe is turned on. Otherwise, continue to turn on the first flow pipe and the second flow pipe simultaneously for a fourth preset time until the temperature difference is greater than the second preset temperature.

[0031] Furthermore, the step of determining whether the temperature difference between the ambient temperature of the first human body and the ambient temperature of the third human body is greater than a second preset temperature, and if so, then only the first flow pipe is opened; otherwise, the first flow pipe and the second flow pipe continue to be opened simultaneously for a fourth preset time until the temperature difference is greater than the second preset temperature, also includes the following steps:

[0032] Determine whether the temperature difference between the ambient temperature of the first human body and the ambient temperature of the third human body is greater than the second preset temperature and less than or equal to the third preset temperature. If so, only the first circulation pipe is opened; otherwise, the first circulation pipe continues to work for a fifth preset time until the third humidity difference is greater than the first preset humidity value and less than or equal to the second preset humidity value.

[0033] The present invention also discloses a control system for a dehumidifier, including a control module. The control module includes a memory and a processor. The memory stores an executable program, which is executed by the processor to implement the control method of the dehumidifier described above.

[0034] After obtaining the ambient humidity, this invention subtracts the first ambient humidity from the preset humidity to obtain a first humidity difference. Then, based on the magnitude of the first humidity difference, it selectively opens the first flow pipe and / or the second flow pipe of the evaporator, thereby enabling the evaporator of the dehumidifier to be in different working states, thus adjusting the outlet air temperature and solving the problem of excessively high outlet air temperature in existing dehumidifiers, which leads to a poor user experience.

[0035] Furthermore, by setting a first flow pipe and a second flow pipe with a length shorter than the first flow pipe, the present invention enables the evaporator to operate through different pipes, thereby improving the efficiency of the dehumidifier evaporator.

[0048] Example 1

[0049] Figure 1 This is a three-dimensional schematic diagram of an evaporator structure according to an embodiment of the present invention. Figure 2 This is a side view of an evaporator structure according to an embodiment of the present invention. Figure 3 This is a first control flowchart according to an embodiment of the present invention. In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the evaporator 1 for the dehumidifier includes a first inlet pipe 10 and a second inlet pipe 20. The first inlet pipe 10 is connected to the outlet pipe 40 through a three-way valve 30 to form a second flow path. The second inlet pipe 20 is also connected to the outlet pipe 40 through a three-way valve 30 to form a first flow path. The length of the first flow path is greater than that of the second flow path, so that the evaporator 1 has different working areas, thereby enabling the evaporator 1 to work selectively.

[0050] Furthermore, when evaporator 1 has different flow lines, the control method for evaporator 1 includes the following steps:

[0051] S1. Obtain the current ambient humidity.

[0052] S2. Subtract the first ambient humidity from the preset humidity to obtain the first humidity difference value;

[0053] S3. Based on the magnitude of the first humidity difference, selectively open the first flow line and / or the second flow line of the evaporator.

[0054] In this embodiment, after the dehumidifier obtains the ambient humidity, it subtracts the first ambient humidity from the preset humidity to obtain a first humidity difference. Then, based on the magnitude of the first humidity difference, it selectively opens the first flow pipe and / or the second flow pipe of the evaporator, thereby enabling the evaporator of the dehumidifier to be in different working states, thereby adjusting the outlet air temperature and solving the problem of excessively high outlet air temperature of dehumidifiers in the prior art, which leads to a poor user experience.

[0055] Furthermore, by setting a first flow pipe and a second flow pipe with a length shorter than the first flow pipe, the present invention enables the evaporator to operate through different pipes, thereby improving the efficiency of the dehumidifier evaporator.

[0056] In a specific embodiment, such as Figure 2 and Figure 4 As shown, after selectively opening the first flow pipe and / or the second flow pipe of the evaporator according to the magnitude of the first humidity difference, if the first humidity difference is greater than the first preset humidity value and less than or equal to the second preset humidity value, then the dehumidifier evaporator is controlled to only open the first flow pipe, so that the dehumidifier evaporator only operates the first flow pipe for a first preset time to complete the dehumidification of the environment.

[0057] After the evaporator has operated only through the first flow path for a first preset time, the following sub-steps are also included:

[0058] S31. Obtain the second ambient humidity after the first preset time when the first flow pipeline is opened;

[0059] S32. Subtract the second ambient humidity from the preset humidity to obtain the second humidity difference value;

[0060] S33. Determine whether the second humidity difference is less than or equal to the first preset humidity value;

[0061] S34. If so, then only the second flow path is opened;

[0062] S35. If not, continue to open only the first flow pipe and make the evaporator continue to work only with the first flow pipe for a first preset time to complete the dehumidification of the environment.

[0063] In this embodiment, the dehumidifier operates by opening only the first flow pipe, without needing to open all the working pipes of the dehumidifier. This reduces the dehumidifier's energy consumption and saves user costs. Furthermore, since the dehumidifier is not fully operational, its service life can be extended.

[0064] In a specific embodiment, such as Figure 2 and Figure 5As shown, after selectively opening the first flow pipe and / or the second flow pipe of the evaporator according to the magnitude of the first humidity difference, if the first humidity difference is greater than the second preset temperature value, the evaporator of the dehumidifier is controlled to simultaneously open the first flow pipe and the second flow pipe, so that the evaporator of the dehumidifier operates the first flow pipe and the second flow pipe for a second preset time to complete the dehumidification of the environment.

[0065] After the dehumidifier evaporator has been operating simultaneously through the first and second flow lines for a second preset time, the following sub-steps are also included:

[0066] S41. Obtain the third ambient humidity after a second preset time when the first and second flow pipelines are simultaneously opened.

[0067] S42. Subtract the third ambient humidity from the preset humidity to obtain the third humidity difference value;

[0068] S43. Determine whether the third humidity difference is greater than the first preset humidity value and less than or equal to the second preset humidity value;

[0069] S44. If so, then only the first flow pipe is opened, so that the dehumidifier evaporator operates only through the first flow pipe.

[0070] S45. If not, continue to open the first circulation pipe and the second circulation pipe simultaneously, and make the first circulation pipe and the second circulation pipe continue to work for a second preset time, until the dehumidifier evaporator works only with the first circulation pipe.

[0071] In this embodiment, if the ambient humidity is greater than the second preset ambient humidity, the evaporator is controlled to operate at maximum power, that is, the first and second flow pipes are opened simultaneously, so that the dehumidifier can quickly dehumidify the environment. After the dehumidifier has been working for the second preset time, the ambient humidity is detected again to determine whether the ambient humidity has changed. If the ambient humidity drops to the second ambient humidity, the dehumidifier is controlled to operate at the second ambient humidity, thereby achieving the purpose of saving dehumidifier energy consumption and avoiding the dehumidifier from always operating at full load.

[0072] Furthermore, by retesting the ambient humidity and adjusting the working flow pipeline of the dehumidifier evaporator in real time based on the retested ambient humidity, the energy consumption of the dehumidifier can be greatly reduced, thereby improving the user experience.

[0073] In other embodiments, if the first humidity difference is less than or equal to the first preset humidity value, the ambient humidity value is not high. It is only necessary to control the dehumidifier evaporator to only open the second flow pipe and make the dehumidifier evaporator work for a specified time with only the second flow pipe open.

[0074] In Example 1, the dehumidifier selects different evaporator working flow pipelines according to different humidity differences. This allows the dehumidifier's working state to be adjusted according to different environmental humidity differences, thereby reducing the dehumidifier's energy consumption. Furthermore, the dehumidifier can be downgraded or upgraded according to different humidity differences, thereby further improving the dehumidifier's working efficiency.

[0075] Example 2

[0076] The difference between Example 2 and Example 1 is that Example 1 is a dehumidifier that operates at a low temperature, and it does not need to consider the impact of high temperature on the dehumidifier. However, Example 2 is a dehumidifier that operates in a high temperature environment. In a high temperature environment, it is necessary not only to ensure the working efficiency of the dehumidifier, but also to ensure that the temperature of the air output by the dehumidifier reaches the preset outlet temperature.

[0077] In one embodiment, such as Figure 2 and Figure 6 As shown, when the dehumidifier detects a first humidity difference greater than a first preset humidity value and less than or equal to a second preset humidity value, it only opens the first flow pipe, causing the dehumidifier evaporator to operate through the first flow pipe. After the dehumidifier evaporator has operated through the first flow pipe for a first preset time, the following sub-steps are also included:

[0078] S51. Obtain the current ambient temperature and the temperature around the first human body;

[0079] S52. Obtain the second ambient temperature of the human body when the ambient temperature is greater than the first preset temperature and the second humidity difference is greater than the first preset humidity value and less than or equal to the second preset humidity value.

[0080] S53. Determine whether the temperature difference between the ambient temperature of the first human body and the ambient temperature of the second human body is greater than the second preset temperature.

[0081] S54. If so, then only the second flow pipe is opened, and the dehumidifier evaporator is controlled to work through the second flow pipe.

[0082] S55. If not, continue to open the first flow pipe so that the dehumidifier evaporator works for the third preset time until the temperature difference is greater than the second preset temperature.

[0083] In this embodiment, the dehumidifier operates in a high-temperature environment, requiring not only the acquisition of ambient temperature via thermal sensors or infrared sensors, but also the acquisition of the ambient temperature around the human body. The ambient temperature around the human body refers to the environmental temperature that can affect a person's perception. By acquiring the current ambient temperature and the ambient temperature around the human body, the dehumidifier evaporator can further adjust the working flow pipeline of the dehumidifier evaporator after detecting the ambient temperature and the ambient temperature around the human body, so that the air output by the dehumidifier reaches the preset temperature, thereby achieving control of the outlet temperature.

[0084] In a further embodiment, such as Figure 2 and Figure 7 As shown, if the dehumidifier detects that the first humidity difference is greater than the second preset temperature value, it controls the dehumidifier evaporator to simultaneously open the first flow pipe and the second flow pipe, so that the dehumidifier evaporator operates the first flow pipe and the second flow pipe for a second preset time to complete the dehumidification of the environment.

[0085] After the dehumidifier evaporator has been operating simultaneously through the first and second flow lines for a second preset time, the following sub-steps are also included:

[0086] S61. Obtain the current ambient temperature and the temperature around the first human body;

[0087] S62. Obtain the third ambient temperature of the human body when the ambient temperature is greater than the first preset temperature and the second humidity difference is greater than the second preset humidity value.

[0088] S63. Determine whether the temperature difference between the ambient temperature of the first human body and the ambient temperature of the third human body is greater than the second preset temperature;

[0089] S64. If so, then only the first flow pipe is opened, and the dehumidifier evaporator is controlled to work through the first flow pipe.

[0090] S65. If not, continue to open the first and second circulation pipes simultaneously, so that the dehumidifier evaporator continues to open the first and second circulation pipes simultaneously and continue to work together for a fourth preset time until the temperature difference is greater than the second preset temperature.

[0091] Furthermore, after the temperature difference is greater than the second preset temperature, it is determined whether the temperature difference between the ambient temperature of the first human body and the ambient temperature of the third human body is greater than the second preset temperature and less than or equal to the third preset temperature. If so, only the first circulation pipe is opened; otherwise, the first circulation pipe continues to work for a fifth preset time until the third humidity difference is greater than the first preset humidity value and less than or equal to the second preset humidity value.

[0092] In this embodiment, by acquiring the current ambient temperature and the ambient temperature of the first human body, the dehumidifier evaporator can further adjust the working flow pipeline of the dehumidifier evaporator after detecting the ambient temperature and the ambient temperature of the first human body, so that the air output by the dehumidifier reaches the preset temperature, thereby realizing the control of the outlet temperature.

[0093] Furthermore, after the dehumidifier has been working for a specified period of time, by re-measuring the ambient humidity and human body temperature, and adjusting the working flow pipeline of the dehumidifier evaporator in real time based on the difference between the re-measuring ambient humidity and human body temperature, the energy consumption of the dehumidifier can be greatly reduced, thereby improving the user experience.

[0094] like Figure 8 As shown, the present invention also discloses a dehumidifier control system 700, wherein the control system 700 includes a control module 70, and the control module 70 includes a memory 702 and a processor 701. The memory 702 stores an execution program 7021, which is executed by the processor 701 to implement the above-mentioned dehumidifier control method.

[0095] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
