Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment for central air conditioning ventilation ducts, and more specifically, to a dust removal device for central air conditioning ventilation ducts. Background Technology

[0002] A central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. Unlike traditional refrigerant-based air conditioners, this system centrally processes air to achieve comfort requirements. After prolonged use, modern central air conditioning systems accumulate a large amount of dust inside the ventilation ducts. This not only pollutes the indoor air and causes illness, but also increases the resistance of the duct system, thereby reducing the airflow of the central air conditioning system.

[0003] Currently, the main methods for cleaning and dust removal of central air conditioning ventilation ducts are professional robot cleaning and manual vacuum cleaner cleaning. Manual vacuum cleaning is labor-intensive and inconvenient to operate in narrow ventilation ducts. Professional robot cleaning requires manual judgment to ensure that the dust removal is thorough. In addition, disinfectant is usually sprayed after cleaning to kill bacteria. This process leaves the ducts damp and has a strong odor, and the sterilization effect needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a dust removal device for central air conditioning ventilation ducts.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A dust removal device for central air conditioning ventilation ducts includes a central air conditioning ventilation duct and a cleaning robot body. The cleaning robot body is placed inside the central air conditioning ventilation duct to scrape off and suck out the dust inside the duct. The cleaning robot body is equipped with a photocatalytic sterilization component, a dust concentration detector, and a voice prompt device electrically connected to the dust concentration detector.

[0007] This device automates the cleaning of the interior of central air conditioning ventilation ducts using a cleaning robot, significantly reducing the labor intensity of manual cleaning. It can also automatically notify users when the interior of the central air conditioning ventilation ducts meets the cleanliness standards, eliminating the need for manual judgment. The device automatically detects and announces the detection results using a dust concentration detector and voice prompts, making it more intelligent. In addition, there is no need to spray disinfectant after the dust removal process. The photocatalytic sterilization component can achieve efficient sterilization without making the interior of the central air conditioning ventilation ducts wet, and it does not produce any odors during the sterilization process, resulting in better sterilization effect.

[0008] Furthermore, the photocatalytic sterilization component includes a U-shaped frame, a photocatalytic substrate, and ultraviolet germicidal lamps. The cleaning robot body is provided with a U-shaped frame, and the U-shaped frame is provided with slots and several ultraviolet germicidal lamps. The photocatalytic substrate is fitted into the slots.

[0009] Furthermore, the cleaning robot body is equipped with a servo motor, which is connected to a U-shaped frame.

[0010] The above solution allows the controller to operate the ultraviolet germicidal lamp while simultaneously removing and exhausting dust. This lamp irradiates the photocatalyst substrate, catalyzing and decomposing the photocatalyst to sterilize and disinfect the interior of the central air conditioning ventilation duct. At the same time, the servo motor controls the photocatalyst sterilization component to rotate at a uniform speed, thereby expanding the sterilization range.

[0011] Furthermore, filters are movably installed at both ends of the central air conditioning ventilation duct.

[0012] Furthermore, the central air conditioning ventilation duct is provided with an insertion hole, the filter screen is attached to the inner wall of the central air conditioning ventilation duct, and a sealing plate that matches the size of the insertion hole is provided on the filter screen, and a handle is provided on the sealing plate.

[0013] The above solution reduces the probability of dust from the surrounding environment of the indoor and outdoor units entering the central air conditioning ventilation duct by installing filters at both ends of the central air conditioning ventilation duct. After a period of use, the filters can be removed by the handle for cleaning or replacement, making the operation convenient.

[0014] Furthermore, the central air conditioning ventilation duct is equipped with a temperature and humidity sensor and a heater electrically connected to the temperature and humidity sensor.

[0015] The above-mentioned solution incorporates temperature and humidity sensors and heaters for two purposes: First, it automatically detects and activates the heaters when the ambient humidity is high, thereby reducing the humidity inside the central air conditioning ventilation ducts, which effectively reduces bacterial growth. Second, it provides heating for the entire central air conditioning ventilation duct system during cold winters, preventing duct freezing and cracking. Furthermore, the central air conditioning duct heaters optimize airflow, reducing the likelihood of moisture condensation on the ducts and extending their lifespan.

[0016] Furthermore, the inner wall of the central air conditioning ventilation duct is provided with an antibacterial and antiviral nano-coating.

[0017] The above solution can further reduce the probability of bacteria or germs growing in the ventilation ducts of central air conditioning through antibacterial and antiviral nano-coating.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Compared to existing technologies, this device automates the cleaning of the interior of central air conditioning ventilation ducts using a cleaning robot, significantly reducing the labor intensity of manual cleaning. It can also automatically notify users when the interior of the ventilation ducts meets cleanliness standards, eliminating the need for manual judgment. A dust concentration detector paired with a voice prompt automatically detects and announces the results, making it more intelligent. Furthermore, after the dust removal process, there is no need to spray disinfectant; the photocatalytic sterilization component achieves efficient sterilization without wetting the interior of the central air conditioning ventilation ducts, and it does not produce any odors during the sterilization process, resulting in superior sterilization effectiveness.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0026] like Figure 1 and Figure 2 As shown, a dust removal device for central air conditioning ventilation ducts includes a central air conditioning ventilation duct 1 and a cleaning robot body 2. The cleaning robot body 2 is placed inside the central air conditioning ventilation duct 1 to scrape off and suck out the dust inside the duct. The cleaning robot body 2 is equipped with a photocatalytic sterilization component, a dust concentration detector 24, and a voice prompt device 25 electrically connected to the dust concentration detector 24.

[0027] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the photocatalytic sterilization component includes a U-shaped frame 22, a photocatalytic substrate 222, and ultraviolet germicidal lamps 23. The cleaning robot body 2 is provided with a U-shaped frame 22, and the U-shaped frame 22 is provided with a slot 221 and a number of ultraviolet germicidal lamps 23. The photocatalytic substrate 222 is fitted inside the slot 221 (the photocatalytic substrate 222 has been fully disclosed in the announcement number CN218328570U, which proposes a photocatalytic disinfection and sterilization machine, and belongs to the prior art without modification).

[0028] In a further optimization of the above embodiment, a servo motor 21 is provided on the cleaning robot body 2, and the servo motor 21 is connected to a U-shaped frame 22.

[0029] In a further refinement of the embodiment of this utility model, an antibacterial and antiviral nano-coating is provided on the inner wall of the central air conditioning ventilation duct 1; the antibacterial and antiviral nano-coating can effectively reduce the probability of bacteria or germs growing in the central air conditioning ventilation duct 1.

[0030] It should be noted that the cleaning robot body 2, ultraviolet germicidal lamp 23, servo motor 21, dust concentration detector 24, and voice prompt device 25 are all electrically connected to the controller, which is not shown in the figure.

[0031] The working process of this utility model is as follows:

[0032] First, a construction door is opened on the central air conditioning ventilation duct 1 to house the cleaning robot body 2 and the sealing airbag. Neither the construction door nor the sealing airbag is shown in the diagram. The sealing airbag is used to block both ends of the central air conditioning ventilation duct 1 during the cleaning process. The placement of the cleaning robot body 2 and its placement into the central air conditioning ventilation duct 1 are existing technologies; commercially available central air conditioning ventilation duct cleaning robots can be used. After the cleaning robot is placed, it is controlled by an external control box and a camera to move along the interior of the central air conditioning ventilation duct 1 and begin the dust removal process. As dust removal progresses, the dust inside the duct is sucked into a dust collector located outside the duct for collection. (The dust removal and suction principles are not described in this application.) After a period of dust removal and cleaning, the dust accumulated inside the central air conditioning ventilation duct 1 is gradually cleaned up. At this time, the dust concentration inside the central air conditioning ventilation duct 1 will decrease. The dust concentration value is detected in real time by the dust concentration detector 24. When the dust concentration values ​​at multiple points inside the central air conditioning ventilation duct 1 drop to the value range set in the controller, the dust concentration detector 24 will send a signal to the controller. The controller will then control the voice prompt 25 to issue a prompt "cleaning completed". The operator outside can then know that the cleaning has been completed and the central air conditioning ventilation duct can be put into normal use.

[0033] While the dust is being removed and the exhaust is being pumped out, the controller controls the ultraviolet germicidal lamp 23 to work and then irradiate the photocatalyst substrate 222. At this time, the photocatalyst can be catalyzed and decomposed to sterilize and disinfect the interior of the central air conditioning ventilation duct 1. At the same time as sterilization, the servo motor 21 can control the photocatalyst sterilization component to rotate at a uniform speed, thereby expanding the sterilization range.

[0034] After sterilization is completed, the staff will drive the cleaning robot to the vicinity of the construction door, then take out the cleaning robot and close the construction door. At this time, the efficient dust removal process inside the central air conditioning ventilation duct 1 can be completed.

[0035] Compared to existing technologies, this device uses a cleaning robot to automatically clean the interior of the central air conditioning ventilation duct 1, significantly reducing the labor intensity of manual cleaning. It can also automatically notify when the interior of the central air conditioning ventilation duct 1 meets the cleaning standards, eliminating the need for manual judgment. The dust concentration detector 24, combined with a voice prompt 25, automatically detects and broadcasts the detection results, making it more intelligent. In addition, after completing the dust removal process, there is no need to spray disinfectant for sterilization. The photocatalytic sterilization component can achieve efficient sterilization without making the interior of the central air conditioning ventilation duct 1 moist, and no odor is generated during the sterilization process, resulting in better sterilization effect.

[0036] In other embodiments, such as Figure 1 and Figure 3As shown, filter screens 3 are movably installed at both ends of the central air conditioning ventilation duct 1. Specifically, the central air conditioning ventilation duct 1 has an insertion hole (not shown in the figure). The filter screen 3 is fitted to the inner wall of the central air conditioning ventilation duct 1, and a sealing plate 32 adapted to the size of the insertion hole is provided on the filter screen 3. A handle 31 is provided on the sealing plate 32. In this embodiment, by installing filter screens 3 at both ends of the central air conditioning ventilation duct 1, the probability of dust from the surrounding environment of the indoor unit and the outdoor unit entering the central air conditioning ventilation duct 1 can be reduced. After a period of use, the filter screen 3 can be removed through the handle 31 for cleaning or replacement, which is convenient. In further optimization of the solution, a sealing element is also provided at the joint between the sealing plate 32 and the insertion hole to ensure the sealing effect during the use of the central air conditioning.

[0037] In some embodiments, such as Figure 1 As shown, a temperature and humidity sensor 4 and a heater 5 electrically connected to the temperature and humidity sensor 4 are installed inside the central air conditioning ventilation duct 1. The temperature and humidity sensor 4 and the heater 5 serve two purposes in this embodiment: First, when the ambient humidity is high, the heater 5 is automatically activated to reduce the humidity inside the central air conditioning ventilation duct, thereby effectively reducing bacterial growth. Second, the heater 5 provides heating for the entire central air conditioning ventilation duct 1 in cold winters, preventing the duct from freezing and cracking. In addition, the heater 5 can also optimize air circulation and reduce the probability of water vapor molecules in the air condensing on the duct, thereby extending the service life of the duct.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
