Description

Technical Field

[0001] The present invention relates to the technical field of air conditioner filters, and particularly to a high-efficiency particulate capture air conditioner filter. Background Art

[0002] The air conditioner filter has a concave-convex honeycomb structure and can be widely used in air filtration and sewage filtration systems. During the spinning stage, antibacterial agents (DEP) and mildew-proof agents (TBZ) are directly incorporated into the PP resin raw material, so that the produced filter screen achieves antibacterial and mildew-proof effects.

[0003] After the air conditioner is used for a period of time, a large amount of dust, dirt, a large number of bacteria and viruses will accumulate on the filter screen, evaporator and air supply system. These harmful substances circulate in the room with the air, pollute the air, spread diseases, and seriously endanger human health. And the dirt will reduce the cooling efficiency of the air conditioner, increase energy consumption, and shorten the service life of the air conditioner. Therefore, the air conditioner must be cleaned after being used for a period of time or when shutting down for seasonal change. Only in this way can you ensure a healthy and fresh air environment.

[0004] In the prior art, manual cleaning is carried out for the particulate matter accumulated on the surface of the air conditioner filter screen. After the particulate matter accumulates on the surface of the air conditioner filter screen, timely cleaning warning and automatic capture of the particulate matter cannot be carried out, which is not conducive to the cleaning and use of the air conditioner filter screen. Summary of the Invention

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention. Specific embodiment one:

[0033] Such as Figures 1 - 3As shown in the figure, an efficient particulate capture air conditioner filter screen includes a filter screen main body 1 and a filter screen frame 3. The filter screen main body 1 is arranged inside the filter screen frame 3. An installation support plate 8 is provided at the bottom edge of the filter screen main body 1. Lighting lights 4 are provided at both side edges of the filter screen frame 3. A density sensor 5, a particulate capturer 6 and a wind speed sensor 7 are sequentially arranged on the surface of the installation support plate 8. A control processor is externally connected to the particulate capturer 6, the wind speed sensor 7 and the density sensor 5. The method for capturing particulates on the surface of the filter screen main body 1 is as follows:

[0034] Sp1: Installation of the filter screen main body 1. The filter screen main body 1 is installed at the air outlet position of the air conditioner, and the lighting lights 4 are powered on;

[0035] Sp2: Particulate capture. The particulate capture is the intermittent lighting of the lighting lights 4. During the lighting, the particulate capturer 6, the density sensor 5 and the wind speed sensor 7 move synchronously to detect the particulate density, the amount of particulates and the wind speed parameters of the filter screen main body 1 on the surface of the filter screen main body 1;

[0036] Sp3: Integration of particulate data. The particulate capture is to transmit the detection data of Sp2 to the control processor for sorting and analysis;

[0037] Sp4: Particulate concentration analysis and early warning. The particulate concentration analysis and early warning is to integrate and analyze the three items of data of Sp3. According to the thresholds and relationships set for particulate density, concentration and wind speed, if the analyzed value exceeds the set threshold range, a cleaning early warning is given.

[0038] Filter screen bars 2 are arranged inside the filter screen frame 3, and the filter screen bars 2 are vertically distributed in longitude and latitude. The filter screen main body 1 is adhesively bonded to the surface of the filter screen bars 2. Lighting lights 4 are arranged on both sides of the surface of the filter screen main body 1 for intermittent lighting, and the amount, distribution density of particulates on the surface of the filter screen main body 1 and the wind speed data of the surface of the filter screen main body 1 affected by the particulates are collected through the particulate capturer 6, the wind speed sensor 7 and the density sensor 5 arranged at the bottom, and the collected data is transmitted to the control processor for integration and analysis. Through the integration and analysis of the three items of data, an early warning is given in time after the threshold value on the surface of the filter screen main body 1 is exceeded, realizing an integrated structure for the collection, analysis and early warning of particulates on the surface of the air conditioner filter screen main body 1. Once the particulate concentration exceeds the set threshold value, an early warning is given and the personnel are prompted to carry out timely maintenance and cleaning, so as to ensure the normal use of the air conditioner. Specific Embodiment 2:

[0040] As Figures 1 - 3As shown, in actual use, since the control processor is connected to an external mobile terminal, the external mobile terminal sets the detection thresholds of the particulate trap 6, the wind speed sensor 7, and the density sensor 5 through the control processor. The control processor is electrically connected to the lighting lamp 4, and the external terminal sets the light intensity, light time, and light interval of the lighting lamp 4 through the control processor. After initializing each sensor module, when the device is powered on, initialization is performed. After the initialization is completed, the particulate trap 6 can detect the particulate concentration on the surface of the filter mesh body 1 in real time, generally substances such as dust and fluff, transmit it to the control processor, and display it. The control processor summarizes and transmits the data detected by each sensor, so as to realize the unified transmission of the particulate concentration data of each sensor to the storage device for unified management and display. Then, it is judged whether the parameters set by the sensor meet the requirements of the device for dust. If not, the parameters of the sensor are reset through the remote communication interface. At the same time, the relationship between the dust concentration and the threshold that the detected device can withstand is judged. Once the dust concentration exceeds the threshold, an alarm is issued to prompt the staff to clean the particles on the corresponding device in time, so as to ensure the normal use of the device.

[0041] In actual use, it is necessary to set the thresholds of the particulate trap 6, the wind speed sensor 7, and the density sensor 5. For example, the concentration of particles captured by the particulate trap 6 is set to m, the density of particles captured by the density sensor 5 is set to n, the wind speed of the filter mesh body 1 captured by the wind speed sensor 7 is set to v, the standard gear wind speed of the air conditioner is set to V, and W is the difference between the standard gear wind speed V of the air conditioner and the actual wind speed v of the filter mesh body 1. When the control processor analyzes, it mainly analyzes the values of m, n, and W. If two or more of the three data exceed the set threshold, a warning is issued. For example, if the particulate density is greater than m, the actual wind speed of the filter mesh body 1 is less than W, and the particulate density n is within the threshold range, a cleaning warning is issued. Specific Embodiment Three:

[0043] As Figures 1 - 3 shown, when the entire system is controlled and used, the control processor internally is provided with a power processing unit, a signal acquisition unit, a data storage and processing unit, a control unit driving unit, and a communication unit.

[0044] Preferably, each unit inside the control processor further includes the following:

[0045] The power processing unit is used to connect to each sensor and control the power supply, and control the on / off of the lighting lamp 4 for power supply;

[0046] The signal acquisition unit is used to pre-process the signals sent by the signal acquisition unit through AD sampling and frequency input capture, then through the analysis and calculation of the processor, and then output drive signals to the control drive unit through the PWM and I / O modules;

[0047] The data storage and processing unit is used to store the collected data;

[0048] The control drive unit is used for the setting control of multiple sensors and lighting tubes;

[0049] The communication unit is used for information transmission and data display and warning.

[0050] The entire control method and acquisition method are based on computer measurement and control technology. Computer measurement and control technology has a wide range of applications in actual production activities. It is an interdisciplinary subject involving computer technology, communication technology, network technology, and automation technology. The measurement and control system uses sensors to convert physical parameters of the measured object, such as temperature, pressure, flow rate, etc., into electrical signals, and then converts these electrical signals into digital signals recognizable by a computer through an experimental device, and displays the numbers, curves, or graphics through a display device. The computer system can store the collected data information in a memory for data analysis, processing, and display, and can transmit the data to the monitoring center as needed. When it is necessary to control the monitored object, it is necessary to judge through the monitoring center and according to the set values of the parameters collected by the measurement and control unit and the actual change situation, etc., in accordance with the specific process requirements, to decide whether to send a control command to the measurement and control unit. The measurement and control unit then outputs corresponding electrical signals in the output device according to a certain control algorithm, and at the same time drives the execution device to perform actions. Specific Embodiment 4:

[0052] As Figures 1 - 3 shown, the surface of the filter screen body 1 is made of fine-denier core-sheath composite monofilament, and the organic-inorganic nano-silver antiviral finishing agent is fixed on the surface of the filter screen body 1 by using chemical cross-linked film coating technology to increase the antiviral and disinfection effects on the surface of the filter screen body 1. During actual use, structures such as automatic disinfection spraying can be added at the installation position of the filter screen body 1 and controlled by a control processor. When the filter screen body 1 is installed, the control processor controls the automatic disinfection spraying structure to spray surface disinfectants such as alcohol and hydrogen peroxide.
