Description

[Technical field]

[0001] The invention relates to the field of air purification, and in particular to a formaldehyde detection display and formaldehyde removal method. [Background technology]

[0002] Formaldehyde is a colorless gas with a pungent odor. It is a type of carcinogen. If you live in an environment with high formaldehyde concentration for a long time, your health will be greatly threatened.

[0003] In recent years, as formaldehyde products have been widely used in interior decoration, the selection and construction of home decoration materials have inevitably caused the problem of excessive indoor formaldehyde. For this reason, users usually need to ask a special formaldehyde detection company to conduct multiple tests and treatments until the formaldehyde concentration is detected to be within a safe range before moving in. However, the economic cost is high. In fact, the release cycle of harmful gases such as formaldehyde is very long and cannot be completely removed in a short time. In addition, the formaldehyde volatilization situation changes under different ambient temperature conditions. Users often cannot predict the indoor formaldehyde volatilization situation and cannot detect the formaldehyde concentration in real time, so they cannot improve the indoor air in a timely and effective manner.

[0004] Therefore, a formaldehyde detection, display and formaldehyde removal method is proposed, which can monitor the indoor formaldehyde concentration in real time and promptly remove the excessively concentrated formaldehyde by wind, with high automation and removal efficiency. [Summary of the invention]

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a formaldehyde detection display and formaldehyde removal method, which can monitor the indoor formaldehyde concentration in real time and promptly remove the excessively concentrated formaldehyde by wind, with high automation and removal efficiency.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A formaldehyde removal method, comprising:

[0008] The formaldehyde sensor is started, and detection data of the formaldehyde sensor is synchronously processed to obtain synchronization data X1 of the current formaldehyde sensor;

[0009] Compare the formaldehyde concentration value X1 with a preset formaldehyde concentration threshold;

[0010] When the formaldehyde concentration value X1 is higher than the preset formaldehyde concentration threshold, if the indoor formaldehyde concentration value is higher than the preset formaldehyde concentration threshold, the air inlet flow rate of the current device is controlled to a small air inlet flow rate to perform formaldehyde removal operation;

[0011] After controlling the air flow rate of the current device to a low-speed air flow rate to perform a formaldehyde removal operation, the method further includes: after a time T1, detecting a current indoor formaldehyde concentration value X2;

[0012] When the current indoor formaldehyde concentration value X2 is still higher than the preset formaldehyde concentration threshold, the air flow rate of the current device is controlled to the mid-range air flow rate;

[0013] After time T2, the current indoor formaldehyde concentration value X3 is detected;

[0014] When the current indoor formaldehyde concentration value X3 is still higher than the preset formaldehyde concentration threshold, the air inlet flow rate of the current device is controlled to a high-end air inlet flow rate;

[0015] Among them, the real-time formaldehyde concentration value P in the calculation environment is calculated, and the calculation formula is P=[K*(X3-X2)-(K-1)*(X2-X1)] / Q, Q is the wind speed, and k is a constant.

[0016] If the formaldehyde concentration value X2 is less than the formaldehyde concentration value X1, the air inlet flow rate of the current device is controlled to a low-speed air inlet flow rate.

[0017] If the formaldehyde concentration value X3 is less than the formaldehyde concentration value X2, the air inlet flow rate of the current device is controlled to a mid-range air inlet flow rate.

[0018] If the formaldehyde concentration value X3 is less than the formaldehyde concentration value X1, the air inlet flow rate of the current device is controlled to a low-speed air inlet flow rate.

[0019] The running time T1 ranges from 0 to 2 hours.

[0020] The running time T2 ranges from 2 to 5 hours.

[0021] If |X2-X1|≤|K*(X3-X1)|, it is judged that the aldehyde content in the environment has changed, otherwise it is judged that only the interfering gas content in the environment has changed.

[0022] A formaldehyde detection display, using the above-mentioned formaldehyde removal method, includes a start module for starting a formaldehyde sensor, and synchronously processing the detection data of the formaldehyde sensor to obtain the current synchronization data X1 of the formaldehyde sensor;

[0023] The comparison module and the wind speed adjustment module are used to compare the formaldehyde concentration value X1 with the preset formaldehyde concentration threshold; when the formaldehyde concentration value X1 is higher than the preset formaldehyde concentration threshold, if the indoor formaldehyde concentration value is higher than the preset formaldehyde concentration threshold, the air inlet flow rate of the current device is controlled to a small air inlet flow rate to perform formaldehyde removal operation;

[0024] After controlling the air flow rate of the current device to a low-speed air flow rate to perform a formaldehyde removal operation, the method further includes: after a time T1, detecting a current indoor formaldehyde concentration value X2;

[0025] When the current indoor formaldehyde concentration value X2 is still higher than the preset formaldehyde concentration threshold, the air flow rate of the current device is controlled to the mid-range air flow rate;

[0026] After time T2, the current indoor formaldehyde concentration value X3 is detected;

[0027] When the current indoor formaldehyde concentration value X3 is still higher than the preset formaldehyde concentration threshold, the air intake flow rate of the current device is controlled to a high-end air intake flow rate.

[0028] It also includes a selection function key. During the operation of the formaldehyde detection display, when the selection function key is triggered, the air purifier is controlled to operate in the wind speed operation mode corresponding to the selection function key.

[0029] A computer-readable storage medium stores a computer program, which implements the steps of the above method when executed by a processor.

[0030] The beneficial effects of the present invention are as follows:

[0031] 1. Start the formaldehyde sensor and perform synchronous processing on the detection data of the formaldehyde sensor to obtain the current synchronization data X1 of the formaldehyde sensor;

[0032] Compare the formaldehyde concentration value X1 with a preset formaldehyde concentration threshold;

[0033] When the formaldehyde concentration value X1 is higher than the preset formaldehyde concentration threshold, if the indoor formaldehyde concentration value is higher than the preset formaldehyde concentration threshold, the air inlet flow rate of the current device is controlled to a small air inlet flow rate to perform formaldehyde removal operation;

[0034] After controlling the air flow rate of the current device to a low-speed air flow rate to perform a formaldehyde removal operation, the method further includes: after a time T1, detecting a current indoor formaldehyde concentration value X2;

[0035] When the current indoor formaldehyde concentration value X2 is still higher than the preset formaldehyde concentration threshold, the air flow rate of the current device is controlled to the mid-range air flow rate;

[0036] After time T2, the current indoor formaldehyde concentration value X3 is detected;

[0037] The current indoor formaldehyde concentration value X3 is still higher than the preset formaldehyde concentration threshold, and the air flow rate of the current device is controlled to a high-end air flow rate;

[0038] The real-time formaldehyde concentration value P in the calculated environment is calculated by the formula P = [K*(X3-X2)-(K-1)*(X2-X1)] / Q, where Q is the wind speed and k is a constant. The low-speed air flow is smaller than the medium-speed air flow, and the medium-speed air flow is smaller than the high-speed air flow. The larger the air flow, the better the formaldehyde removal effect.

[0039] For example, X3 is 0.4, X2 is 0.215, X1 is 0.112, K is 2, Q is 3.2, and P=0.147.

[0040] If the formaldehyde concentration value X2 is less than the formaldehyde concentration value X1, the air inlet flow rate of the current device is controlled to a low-speed air inlet flow rate.

[0041] The wind speed is the highest at the wind speed center and gradually decreases towards the surrounding areas. Only relying on formaldehyde detectors to monitor formaldehyde in the air will result in large errors and may easily lead to multiple jumps in low-speed wind mode, medium-speed wind mode and high-speed wind mode. In order to avoid multiple jumps in the indoor formaldehyde concentration value between higher than the preset formaldehyde concentration threshold and lower than the preset formaldehyde concentration threshold in a short period of time, resulting in increased operating power consumption and even braking problems, relevant calculations are performed in a timely manner based on the formaldehyde concentration and the operating wind speed. On the basis of effectively reducing the formaldehyde concentration, energy consumption is reduced, and at the same time, it is convenient for users to grasp the formaldehyde concentration-related information conveniently and intuitively.

[0042] 2. If the formaldehyde concentration value X3 is less than the formaldehyde concentration value X2, the air inlet flow rate of the current device is controlled to a mid-range air inlet flow rate.

[0043] If the formaldehyde concentration value X3 is less than the formaldehyde concentration value X1, the air inlet flow rate of the current device is controlled to a low-speed air inlet flow rate.

[0044] 3. If |X2-X1|≤|K*(X3-X1)|, it is judged that the aldehyde content in the environment has changed, otherwise it is judged that only the interfering gas content in the environment has changed.

[0045] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

Brief Description of the Drawings

[0046] The present invention will be further described below in conjunction with the accompanying drawings:

[0047] Figure 1 This is a flow chart of Embodiment 1 of the present invention. [Specific implementation method]

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] The following first describes the concepts involved in this application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of this application easier to understand and does not limit the scope of protection of this application.

[0050] Embodiment 1:

[0051] A formaldehyde removal method, such as Figure 1 Shown, including

[0052] The formaldehyde sensor is started, and detection data of the formaldehyde sensor is synchronously processed to obtain synchronization data X1 of the current formaldehyde sensor;

[0053] Compare the formaldehyde concentration value X1 with a preset formaldehyde concentration threshold;

[0054] When the formaldehyde concentration value X1 is higher than the preset formaldehyde concentration threshold, if the indoor formaldehyde concentration value is higher than the preset formaldehyde concentration threshold, the air inlet flow rate of the current device is controlled to a small air inlet flow rate to perform formaldehyde removal operation;

[0055] After controlling the air flow rate of the current device to a low-speed air flow rate to perform a formaldehyde removal operation, the method further includes: after a time T1, detecting a current indoor formaldehyde concentration value X2;

[0056] When the current indoor formaldehyde concentration value X2 is still higher than the preset formaldehyde concentration threshold, the air flow rate of the current device is controlled to the mid-range air flow rate;

[0057] After time T2, the current indoor formaldehyde concentration value X3 is detected;

[0058] The current indoor formaldehyde concentration value X3 is still higher than the preset formaldehyde concentration threshold, and the air flow rate of the current device is controlled to a high-end air flow rate;

[0059] The real-time formaldehyde concentration value P in the calculation environment is calculated using the formula P = [K*(X3-X2)-(K-1)*(X2-X1)] / Q, where Q is the wind speed and k is a constant. The low-speed air intake flow is smaller than the medium-speed air intake flow, and the medium-speed air intake flow is smaller than the high-speed air intake flow. The larger the air intake flow, the better the formaldehyde removal effect, and the preset formaldehyde concentration threshold is 0.05.

[0060] For example, X3 is 0.4, X2 is 0.215, X1 is 0.112, K is 2, Q is 3.2, and P=0.147.

[0061] If the formaldehyde concentration value X2 is less than the formaldehyde concentration value X1, the air inlet flow rate of the current device is controlled to a low-speed air inlet flow rate.

[0062] The wind speed is the highest at the wind speed center and gradually decreases towards the surrounding areas. Only relying on formaldehyde detectors to monitor formaldehyde in the air will result in large errors and may easily lead to multiple jumps in low-speed wind mode, medium-speed wind mode and high-speed wind mode. In order to avoid multiple jumps in the indoor formaldehyde concentration value between higher than the preset formaldehyde concentration threshold and lower than the preset formaldehyde concentration threshold in a short period of time, resulting in increased operating power consumption and even braking problems, relevant calculations are performed in a timely manner based on the formaldehyde concentration and the operating wind speed. On the basis of effectively reducing the formaldehyde concentration, energy consumption is reduced, and at the same time, it is convenient for users to grasp the formaldehyde concentration-related information conveniently and intuitively.

[0063] If the formaldehyde concentration value X3 is less than the formaldehyde concentration value X2, the air inlet flow rate of the current device is controlled to a mid-range air inlet flow rate, and the gear is changed in time to save energy.

[0064] If the formaldehyde concentration value X3 is less than the formaldehyde concentration value X1, the air inlet flow rate of the current equipment is controlled to a small-gear air inlet flow rate, and the gear is changed in time to save energy.

[0065] The value range of the running time T1 is 0-2h, and the running time can be changed as needed, such as 15min.

[0066] The value range of the running time T2 is 2-5h, and the running time can be changed as needed, such as 30min. Generally, the running time T2 is greater than the running time T1.

[0067] If |X2-X1|≤|K*(X3-X1)|, it is judged that the aldehyde content in the environment has changed, otherwise it is judged that only the interfering gas content in the environment has changed.

[0068] A formaldehyde detection display, using the above-mentioned formaldehyde removal method, includes a start module for starting a formaldehyde sensor, and synchronously processing the detection data of the formaldehyde sensor to obtain the current synchronization data X1 of the formaldehyde sensor;

[0069] The comparison module and the wind speed adjustment module are used to compare the formaldehyde concentration value X1 with the preset formaldehyde concentration threshold;

[0070] When the formaldehyde concentration value X1 is higher than the preset formaldehyde concentration threshold, if the indoor formaldehyde concentration value is higher than the preset formaldehyde concentration threshold, the air inlet flow rate of the current device is controlled to a small air inlet flow rate to perform formaldehyde removal operation;

[0071] After controlling the air flow rate of the current device to a low-speed air flow rate to perform a formaldehyde removal operation, the method further includes: after a time T1, detecting a current indoor formaldehyde concentration value X2;

[0072] When the current indoor formaldehyde concentration value X2 is still higher than the preset formaldehyde concentration threshold, the air flow rate of the current device is controlled to the mid-range air flow rate;

[0073] After time T2, the current indoor formaldehyde concentration value X3 is detected;

[0074] When the current indoor formaldehyde concentration value X3 is still higher than the preset formaldehyde concentration threshold, the air intake flow rate of the current device is controlled to a high-end air intake flow rate.

[0075] It also includes a selection function key. During the operation of the formaldehyde detection display, when the selection function key is triggered, the air purifier is controlled to operate in the wind speed operation mode corresponding to the selection function key.
