Description

[0002] Traditional indoor air purifiers mainly focus on filtering and purifying air to remove pollutants in the air, such as particulate matter, bacteria, viruses, harmful gases, etc., so as to improve indoor air quality and reduce the impact on human health. However, as people's requirements for energy efficiency and comfort continue to increase, the shortcomings of traditional purifiers in energy consumption and heat exchange efficiency have gradually become apparent. In terms of reducing heating or cooling requirements, traditional heat exchange devices usually include heat exchange devices that can use the heat or cold in the exhaust air to pre-treat the fresh air.

[0044] Example 1

[0045] See also Figure 1-Figure 16 As shown, the purpose of this embodiment is to provide an indoor air purifier, including a shell 3, and the side wall of the shell 3 is provided with a plurality of air holes. Through the design of the air holes, a channel is provided for the exchange of indoor and outdoor air with the air inside the purifier, ensuring that the air can smoothly enter and exit the shell 3, thereby realizing the ventilation function of the purifier. The inside of the shell 3 is provided with a plurality of blowing structures 2 around its central array. The blowing structure 2 stirs the air so that the air flows from one diagonal side of the shell 3 to the other diagonal side. This diagonal flow path can effectively separate the fresh air and the exhaust air, avoid cross contamination of the air flow, and optimize the air flow path at the same time. The fresh air and the exhaust air are respectively along the two diagonal directions of the shell 3. Linear flow increases the contact area between fresh air and exhaust air, realizes efficient heat exchange between fresh air and exhaust air, reduces air flow resistance at the same time, and improves the operating efficiency of the purifier. A filter plate 4 is installed between the blowing structure 2 and the outer shell 3. The filter plate 4 filters the air to remove dust, particulate matter and pollutants in the air, thereby improving the air quality. The blowing structure 2 allows the air to pass through the side wall of the outer shell 3 and the filter plate 4 in sequence before entering the blowing structure 2, and then passes through the filter plate 4 and the side wall of the outer shell 3 from the other side of the blowing structure 2 in sequence, ensuring that the air has been purified before entering the blowing structure 2, and at the same time passes through the filter plate 4 and the side wall of the outer shell 3 again when discharged, further improving the purification effect.

[0046] See also Figure 1-Figure 7 As shown, diamond holes are arranged between several blowing structures 2, and a heat exchange core structure 1 is arranged in the diamond holes. Through the heat exchange core structure 1, fresh air and exhaust air exchange heat during the flow process, which can effectively recover the heat in the exhaust air, improve energy utilization efficiency, and reduce energy consumption. The heat exchange core structure 1 guides the air so that the air flows through the two blowing structures 2 on the two diagonals of the outer shell 3 respectively, further optimizing the air flow path and improving the purification efficiency. The heat exchange core structure 1 includes several vertical rods 13, and an air duct control structure 12 is arranged between the several vertical rods 13. Through the combined design of the vertical rods 13 and the air duct control structure 12, the air flow path inside the heat exchange core structure 1 is optimized, and the heat exchange efficiency is improved. A staggered sliding structure 11 is arranged above the air duct control structure 12, and the staggered sliding structure 11 is used to realize dynamic adjustment of the air duct cross-section height, thereby controlling the air flow rate according to needs and improving the flexibility and adaptability of the equipment.

A vertical air duct is disposed between the first variable pitch structure 123 and the second variable pitch structure 124, and the fresh air and the exhaust air flow along the air duct. This design can further optimize the air flow path, reduce resistance, and improve the heat exchange efficiency. The dislocated sliding structure 11 moves to change the cross-sectional height of the air duct between the first variable pitch structure 123 and the second variable pitch structure 124, and the Bernoulli theorem is used to control the air flow rate. By reducing the cross-sectional area of ​​the air duct, the air flow rate is significantly increased, thereby enhancing the heat exchange efficiency of the fresh air and the exhaust air in the heat exchange core, which can effectively improve the energy-saving performance and purification efficiency of the purifier.

The first variable pitch structure 123 includes two fresh air lifting rods 1233 fixedly connected between the two rising rods 1111. The two fresh air lifting rods 1233 are respectively arranged below the opposite sides of the rising plate 111. Through the arrangement of the fresh air lifting rods 1233, the movement of the rising rods 1111 is transmitted to the fresh air top strip 1231, thereby realizing the structure. The fresh air top strips 1231 are arranged on the lower side of the fresh air duct through the design of the fresh air top strips 1231, which directly act on the fresh air duct, and provide key components for adjusting the cross-sectional height of the fresh air duct. The rising plate 111 slides upward, and drives the fresh air top strips 1231 to slide upward through the rising rod 1111 and the fresh air lifting rod 1233, thereby reducing the cross-sectional height of the fresh air duct from the bottom.

Through this vertical layout, the fresh air and the exhaust air flow alternately in the heat exchange core, which significantly increases the contact area and contact time between the two, thereby improving the heat exchange efficiency between the fresh air and the exhaust air. The rising plate 111 slides upward to drive the exhaust top bar 1241 to slide upward through the rising rod 1111 and the exhaust lifting rod 1243, thereby reducing the cross-sectional height of the exhaust air duct from the bottom.

Through the design of the exhaust pressure strips 1232, they directly act on the upper part of the exhaust duct, providing a key component for adjusting the cross-sectional height of the exhaust duct from the top, further enhancing the ability to control the exhaust flow rate. The descending plate 112 slides downward, driving the exhaust pressure strip 1232 to slide downward through the descending rod 1121 and the exhaust pressure rod 1234, reducing the cross-sectional height of the exhaust duct from the top, realizing two-way adjustment of the cross-sectional height of the exhaust duct at the top and bottom, further optimizing the exhaust flow rate, improving the heat exchange efficiency, and enhancing the flexibility and adaptability of the equipment.

The existence of the third grooves provides precise guidance for the movement of the exhaust top strip 1241, ensuring its smooth and reliable movement while avoiding displacement or jamming during the movement, and a plurality of fourth grooves perpendicular to the third grooves are provided on the bottom surface of the exhaust heat exchange plate 1245, and the fresh air pressure strip 1242 is slidably inserted in the fourth grooves from below, thereby realizing dynamic adjustment of the cross-sectional height of the fresh air duct.

[0055] See also Fig.13As shown, an upper fixing plate 121 is fixedly installed below the top plate 14, and a lower fixing plate 122 is fixedly installed above the bottom plate 15, which provides additional support and stability for the entire heat exchange core structure 1, and also provides a basis for the installation and movement of the air duct control structure 12. Fresh air shields 125 are fixedly installed on both sides above the fresh air heat exchange plate 1235 parallel to the fresh air top strip 1231, and exhaust air shields 126 are fixedly installed on both sides below the fresh air heat exchange plate 1235 parallel to the exhaust top strip 1241, forming a fresh air duct and an exhaust air duct. The physical separation of the air duct ensures that the fresh air and the exhaust air do not interfere with each other during the flow process, and guides the airflow along the predetermined path. A number of fresh air heat exchange plates 1235 and exhaust air heat exchange plates 1245 are connected in turn through the fresh air wind shield 125 and the exhaust air wind shield 126. This design enables the fresh air heat exchange plates 1235 and the exhaust air heat exchange plates 1245 to be interconnected through the fresh air wind shield 125 and the exhaust air wind shield 126 to form an integral heat exchange structure, further optimizing the air flow path, while enhancing the stability and reliability of the entire structure. The air blowing structure 2 includes a ventilation frame 21, and a plurality of fans 22 are fixedly installed on the outer wall of the ventilation frame 21. The fan 22 stirs the air flow by rotating the fan blades to provide power for the flow of fresh air and exhaust air, ensuring that the air can circulate efficiently inside the purifier. The fan 22 on the ventilation frame 21 on a diagonal line of the shell 3 drives the air into the fresh air duct parallel to the fresh air shield 125 until it is blown into the room. The fan 22 on the ventilation frame 21 on another diagonal line of the shell 3 drives the air into the fresh air duct parallel to the exhaust air shield 126. The exhaust air duct is blown out to the outside. This design utilizes the diagonal layout inside the shell 3 to separate the flow paths of fresh air and exhaust air. The fresh air is driven into the fresh air duct and the fresh air shield 125 through the fan blade fan 22 on one diagonal line, and is blown into the room after heat exchange; the exhaust air is driven into the exhaust duct and the exhaust air shield 126 through the fan blade fan 22 on another diagonal line, and is discharged to the outside after heat exchange. This layout not only optimizes the air flow path, but also improves the heat exchange efficiency, while avoiding cross contamination between fresh air and exhaust air.

[0056] When this embodiment is used, indoor air enters the purifier through the air holes on the side wall of the shell 3, and is preliminarily filtered through the filter plate 4 to remove dust and impurities to ensure air cleanliness; the fresh air and exhaust air enter the heat exchange core structure 1 along the diagonal flow paths inside the shell 3 respectively. In areas where it is cold in winter and hot in summer, the temperature difference between indoor and outdoor air is large. This device uses the fresh air heat exchange plate 1235 and the exhaust air heat exchange plate 1245 in the heat exchange core structure 1 to fully exchange heat between the fresh air and the exhaust air in the vertically staggered air duct. The fresh air obtains heat or cold from the exhaust air, thereby significantly reducing the load of the air conditioning or heating equipment and improving energy utilization efficiency. For example, in winter, the temperature of the fresh air increases after heat exchange, reducing the heating amount of the indoor heating equipment; in summer, the fresh air temperature decreases and is dried, reducing the indoor The refrigeration load of the indoor air conditioner; the motor 16 drives the shaft to rotate, and the gear on the shaft is engaged with the rising tooth plate 1112 and the descending tooth plate 1122 fixed on the rising plate 111 and the descending plate 112. When the gear rotates, the rack drives the rising plate 111 and the descending plate 112 to slide up and down alternately, and the movement of the rising plate 111 and the descending plate 112 is transmitted to the first variable pitch structure 123 and the second variable pitch structure 124 in the air duct control structure 12 through the linkage components of the fresh air top bar 1231 and the exhaust air top bar 1241, thereby reducing the cross-sectional height of the fresh air and exhaust air ducts. According to Bernoulli's theorem, reducing the cross-sectional area of ​​the air duct can increase the air flow rate, thereby enhancing the heat exchange efficiency, ensuring that under the condition of large temperature difference, the heat recovery effect is still significant, avoiding energy waste caused by large temperature difference.
