Description

Technical Field

[0001] This invention relates to the technical field of dehumidifier control, and particularly to an intelligent control method for dehumidifiers based on temperature and humidity sensors. Background Technology

[0002] Existing dehumidifiers are all fixedly placed in specific locations within an indoor space and operate according to a predetermined mode. This predetermined mode means the dehumidifier can only operate at a fixed suction power, and it cannot adapt its dehumidification to the actual temperature and humidity of the indoor space. Furthermore, the fixed placement of existing dehumidifiers limits their actual dehumidification coverage within the indoor space, making it impossible to guarantee a balanced humidity level throughout the room. This increases power consumption and reduces the level of intelligence in their operation. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an intelligent control method for dehumidifiers based on temperature and humidity sensors. Multiple temperature and humidity sensors are distributed across different sub-spaces within the indoor space where the portable dehumidifier is located to collect temperature and humidity data for the corresponding areas. Simultaneously, the portable dehumidifier is instructed to circulate through all sub-spaces in a predetermined sequence. Based on the temperature and humidity data, the fan speed of the portable dehumidifier and the duration of dehumidification operation in each sub-space during a single cycle are determined. Thus, as the portable dehumidifier circulates within the indoor space, it performs dehumidification for different durations and adjusts the fan speed for different sub-spaces, ensuring overall humidity balance in the indoor space, reducing power consumption, and enhancing the dehumidifier's intelligent operation.

[0004] This invention provides an intelligent control method for dehumidifiers based on temperature and humidity sensors, comprising the following steps:

[0005] Step S1: Divide the indoor space where the portable dehumidifier is located into several sub-spaces, and install the same number of temperature and humidity sensors in each sub-space; instruct all temperature and humidity sensors in each sub-space to collect temperature and humidity data of their respective areas;

[0006] Step S2: Based on the collected temperature and humidity data, determine the weighted average temperature value and weighted average humidity value of each subspace; and instruct the portable dehumidifier to sequentially and cyclically traverse all subspaces in a predetermined order.

[0012] It instructs all temperature and humidity sensors in each cuboid subspace to synchronously collect temperature and humidity data for their respective areas at the same sampling frequency.

[0013] Furthermore, in step S2, determining the weighted average temperature value and weighted average humidity value for each subspace based on the collected temperature and humidity data specifically includes:

[0014] Using the formula (1) below, the weighted average temperature and weighted average humidity values ​​for each subspace are determined based on the collected temperature and humidity data.

[0016] In the above formula (1), W(a) represents the weighted average temperature value of the a-th subspace; Q(a) represents the weighted average humidity value of the a-th subspace; w(a_i) represents the temperature value collected by the i-th temperature and humidity sensor in the a-th subspace; q(a_i) represents the humidity value collected by the i-th temperature and humidity sensor in the a-th subspace; H(a_i) represents the installation height of the i-th temperature and humidity sensor in the a-th subspace in the indoor space; and n(a) represents the total number of temperature and humidity sensors installed in the a-th subspace.

[0017] Furthermore, in step S2, instructing the portable dehumidifier to sequentially and cyclically traverse all subspaces in a predetermined order specifically includes:

[0018] The movable dehumidifier is instructed to move sequentially and cyclically through all cuboid subspaces along a preset path; wherein the preset path includes sub-path segments corresponding to each cuboid subspace, and all sub-path segments have the same length.

[0019] Furthermore, in step S3, controlling the fan speed of the portable dehumidifier based on the weighted average temperature value and the weighted average humidity value specifically includes:

[0020] Using the formula (2) below, the rotational speeds of the dehumidifying fan located at the front of the portable dehumidifier and the exhaust fan located at the back of the portable dehumidifier are determined based on the weighted average humidity value.

[0021]

[0022] In the above formula (2), v(a) represents the rotational speed of the dehumidifying fan and the exhaust fan when the portable dehumidifier moves to the a-th subspace; v max The maximum rotational speed of the dehumidifying fan and the exhaust fan of the portable dehumidifier is indicated; m represents the total number of cuboid subspaces contained in the indoor space, and m = 6; Q0 represents the unit temperature value, and Q0 = 1℃; | represents taking the absolute value.

[0023] Furthermore, in step S4, based on the weighted average temperature value and the weighted average humidity value, the duration of dehumidification operation in each subspace during one cycle of movement through all subspaces of the portable dehumidifier specifically includes:

[0024] Using the formula (3) below, based on the weighted average temperature value, determine the duration of dehumidification operation in each subspace during one cycle of movement through all subspaces of the portable dehumidifier.

[0027] Furthermore, in step S4, when the portable dehumidifier is stationary in each subspace performing dehumidification, instructing the portable dehumidifier to perform a 360° circumferential rotation specifically includes:

[0029] Compared to existing technologies, this intelligent control method for dehumidifiers based on temperature and humidity sensors involves distributing multiple temperature and humidity sensors across different sub-spaces within the indoor space where the portable dehumidifier is located. These sensors collect temperature and humidity data for the corresponding areas and instruct the portable dehumidifier to circulate through all sub-spaces in a predetermined sequence. Based on the temperature and humidity data, the method determines the fan speed and the duration of dehumidification in each sub-space during a single cycle. This allows the portable dehumidifier to perform dehumidification for varying durations and fan speeds in different sub-spaces as it circulates within the indoor space, ensuring overall humidity balance, reducing power consumption, and enhancing the dehumidifier's intelligent operation.

Based on the temperature and humidity data, the fan speed of the portable dehumidifier is determined, as well as the duration of dehumidification operation in each sub-space during a single cycle. Thus, when the portable dehumidifier circulates back and forth within the indoor space, it performs dehumidification operations and adjusts the fan speed for different sub-spaces it passes through, ensuring overall humidity balance in the indoor space, reducing power consumption, and improving the intelligent operation of the dehumidifier.

[0041] Preferably, in step S1, dividing the indoor space where the portable dehumidifier is located into several sub-spaces and distributing the same number of temperature and humidity sensors in each sub-space specifically includes:

By dividing the indoor space into equal volumes, it is possible to ensure that the humidity of each rectangular sub-space can be adjusted in a targeted manner during the subsequent mobile dehumidification process in the indoor space.

[0044] Preferably, in step S1, instructing all temperature and humidity sensors in each subspace to collect their own temperature and humidity data for that area specifically includes:

[0045] It instructs all temperature and humidity sensors in each cuboid subspace to synchronously collect temperature and humidity data for their respective areas at the same sampling frequency.

In this way, the portable dehumidifier can adapt to the dehumidification of subspaces located in different positions in the indoor space during the movement, ensuring the uniformity of dehumidification of the indoor space by the portable dehumidifier.

[0055] Preferably, in step S3, controlling the fan speed of the portable dehumidifier based on the weighted average temperature value and the weighted average humidity value specifically includes:

In this way, while ensuring that each subspace can independently carry out dehumidification to a certain degree, the temperature and humidity adjustment of the space can also be made more even, and the overall dehumidification time of the portable dehumidifier remains unchanged.

[0065] Preferably, in step S4, when the portable dehumidifier is stationary in each subspace performing dehumidification, instructing the portable dehumidifier to perform a 360° circumferential rotation specifically includes:

[0066] When the portable dehumidifier is stationary in each subspace to perform dehumidification, it is instructed to rotate 360° circumferentially at half the speed of the dehumidifying fan and the exhaust fan.

[0067] The beneficial effect of the above technical solution is that the portable dehumidifier can rotate 360° circumferentially at half the speed of the dehumidifying fan and the exhaust fan, which enables the portable dehumidifier to perform all-round dehumidification treatment on each subspace.

[0068] As can be seen from the above embodiments, this intelligent control method for dehumidifiers based on temperature and humidity sensors involves distributing multiple temperature and humidity sensors in different sub-spaces corresponding to the indoor space where the portable dehumidifier is located. These sensors collect temperature and humidity data for the corresponding areas and instruct the portable dehumidifier to sequentially circulate through all sub-spaces in a predetermined order. Based on the temperature and humidity data, the method determines the fan speed of the portable dehumidifier and the duration of dehumidification operation in each sub-space during a single cycle. Thus, as the portable dehumidifier circulates back and forth within the indoor space, it performs dehumidification operations and adjusts the fan speed for different sub-spaces, ensuring overall humidity balance in the indoor space, reducing power consumption, and improving the dehumidifier's intelligent operation.
