Description

Technical Field

[0001] This invention relates to a ventilator that removes dust, moisture, bacteria, and provides sound absorption, noise reduction, and heat exchange. It is installed in a ventilation opening on a building wall. Outdoor air containing moisture, dust, bacteria, harmful substances, and noise flows into the ventilator through the air pressure difference between indoors and outdoors. This process purifies the air, removes moisture, and provides sound absorption, noise reduction, and heat exchange, improving the indoor air environment and space for human health. It also contributes to energy conservation, carbon reduction, and emission reduction in the fields of air conditioning and environmental protection. Background Technology

[0002] Exposure to cold air containing moisture, dust, and harmful substances, along with noise, can disrupt sleep and health, leading to respiratory, cardiovascular, and nervous system disorders. Currently, residential natural ventilation and fresh air systems lack the functions of dust removal, dehumidification, sterilization, sound absorption, noise reduction, and heat exchange for the air flowing into the room. To prevent and eliminate the spread and harm of moisture, dust, and harmful substances, along with noise, existing natural ventilation and fresh air systems should be innovatively designed with dust removal, dehumidification, sterilization, sound absorption, noise reduction, and heat exchange technologies. This can reduce the health hazards posed by airborne dust, bacteria, harmful substances, and noise. Summary of the Invention

[0015] The aforementioned dust removal, dehumidification, noise reduction, and purification device baffles and strong adhesive are fixed to the two sides of the circular filter plate on the right and left sides of the air inlet and the central shaft. This ensures the unobstructed flow of airflow filtration channels within the dust removal, dehumidification, noise reduction, and purification device, forming a dust removal, dehumidification, noise reduction, and purification device with four or more geometrically shaped gas filtration channels. Within one geometrically shaped gas filtration channel, there are two right-side C-shaped grooves and two left-side C-shaped grooves, as well as two left-side herringbone-shaped collection grooves.

[0016] After being heated by the cold air through four or more air intake channels in the Venturi heating device, the air flows into the dust removal, dehumidification, noise reduction, and purification device through four or more geometrically shaped gas filtration channels. The cold air contacts the geometrically shaped plate wall within one of the gas filtration channels, resulting in boundary friction and inertial rigid collisions. It also contacts the left and central sound-absorbing baffles, resulting in flexible collisions, forming a vortex backflow and centrifugal force. Under the action of centrifugal force, sixteen negative pressure zones can be formed. Utilizing the principle of air heat exchange, the indoor hot air and the heated outdoor cold air flowing in from the left exhaust port and right air intake port within one of the gas filtration channels undergo convection and collisions, resulting in a delay in flow velocity. After heat and cold exchange treatment, the air flows out into the room; then, under the action of centrifugal force, the moisture, dust and noise in the air containing moisture, dust and noise are captured and condensed in the negative pressure area, while the left sound-absorbing baffle and the central sound-absorbing baffle treat the noise reduction; the catalytic oxidation material of titanium dioxide coated and set in the dust removal, dehumidification and noise reduction purification device and the LED light strip, when the switch connecting the LED light strip to the LED light strip wires and the transformer and the indoor power supply is turned on, the white light source of the LED light strip can drive the catalytic oxidation ability of the titanium dioxide material, decompose the germs and harmful substances adhering to the dust in the airflow filtration channel and negative pressure area and play a sterilization role.

[0023] The device of this invention has a simple, compact, and reasonable structure. Its working principle is as follows: A ventilator for dust removal, dehumidification, sterilization, sound absorption, noise reduction, and heat exchange is installed on the ventilation opening of the building wall. The heating electric heating wire inside the Venturi heating device is connected to an external indoor power supply line, socket, and temperature heating controller. The temperature sensor and temperature sensor wire inside the Venturi heating device are connected to a temperature display and power supply. The wires connecting the LED light strip and the LED light strip, as well as the transformer and power supply, are turned on to start the temperature heating controller and temperature sensor. The cold outdoor air containing moisture, bacteria, harmful substances, and noise adhering to dust is induced by the pressure difference between indoor and outdoor air. It flows through the rain cover, air intake grille, and pressure difference between the insect filter and air guide pipe inside the ventilator for dust removal, dehumidification, sterilization, sound absorption, noise reduction, and heat exchange, and is heated by the Venturi heating device. After coarse filtration of dust and moisture by the outdoor dust removal filter cloth, it enters the dust removal, dehumidification, noise reduction, and purification device. Based on the principles of Fourier series transform and inverse transform, sine and cosine functions, and linear transformation of periodic phase angle, a filter module for a dust removal, dehumidification, noise reduction, and purification device is constructed with air inlet and outlet holes to form a certain waveform frequency domain. This module incorporates sound-absorbing material within the airflow filtration channel and negative pressure area. When air comes into contact with the titanium dioxide, sound-absorbing material, and LED light strips coated and installed within the device, the illuminated white light from the LED strips drives the catalytic oxidation of the titanium dioxide material. This catalytic oxidation decomposes bacteria and harmful substances adhering to moisture and dust, resulting in dust removal, dehumidification, sterilization, sound absorption, noise reduction, and heat exchange treatment of the cold air. After purification by the indoor dust filter cloth, the air flowing into the room reaches a temperature above 16 degrees Celsius. This achieves a 95% removal rate of moisture and PM2.5 particles, a sterilization effect of over 95%, and a sound absorption and noise reduction effect of over 33 decibels.

After being heated by cold air through four or more air intake channels within the Venturi heating device, the air flows into four or more geometrically shaped gas filtration channels within the dust removal, dehumidification, and noise reduction purification device. The cold air encounters boundary friction and inertial rigid collisions with the geometrically shaped plate walls within one of the gas filtration channels, and also experiences flexible collisions with the left and central sound-absorbing baffles, forming a vortex backflow and centrifugal force. Under the action of centrifugal force, sixteen negative pressure zones can be created. Utilizing the principle of air heat exchange, the indoor hot air convects and collides with the heated outdoor cold air flowing in from the left exhaust port and right air intake port within one of the gas filtration channels, resulting in a delay in flow velocity. After heat and cold exchange, the air flows out into the room; then, under the action of centrifugal force, the moisture, dust and noise in the air containing moisture, dust and noise are captured and condensed in the negative pressure area, while the left sound-absorbing baffle and the central sound-absorbing baffle treat the noise reduction; the catalytic oxidation material of titanium dioxide coated and set in the dust removal, dehumidification and noise reduction purification device and the LED light strip, when the switch connecting the LED light strip to the LED light strip wires and the transformer and indoor power is turned on, the white light source of the LED light strip can drive the catalytic oxidation ability of the titanium dioxide material, decompose the germs and harmful substances adhering to the dust in the airflow filtration channel and negative pressure area and play a sterilization role.
