The left side of the main exterior surface 131 is connected to the second connection surface 133 . A display panel 139 for displaying control information is further attached to the main exterior surface 131 .

As shown in FIGS. 2a, 2b and 2c, the air purification and ventilation device includes an intake chamber 22, an air purification chamber 23, an airflow distribution chamber 24 and an exhaust chamber 25. FIG. Both the intake chamber 22 and the airflow distribution chamber 24 communicate with the air purification chamber 23 .

As shown in FIGS. 2b and 2c, the intake chamber 22 is provided with an intake fan 31 . An air purification assembly 32 is provided in the air purification chamber 23 . An exhaust fan 33 is provided in the exhaust chamber 25 .

As shown in Figures 1a and 2b, the intake chamber 22 has air vents 221/222 for communicating with the interior space.

As shown in FIGS. 1a, 2b and 2c, the airflow distribution chamber 24 has a new air inlet 2411/2412 for communicating with the outdoor space and a suction inlet 2421/2422 for communicating with the indoor space. When the intake fan 31 rotates, the air purification and ventilation device can realize the following three basic working patterns.

The first basic operating pattern is the fresh air intake operating pattern, which draws in fresh air from the outdoor space, purifies it, and then sends it to the indoor space. Air enters the airflow distribution chamber 24 through the fresh air vents 2411 / 2412 and then flows to the air purification chamber 23 . The air intake chamber 22 takes in the air purified from the air purification chamber 23 and sends it to the indoor space through the air outlets 221/222.

The second basic operating pattern is the internal circulation operating pattern, which draws in turbid air from the indoor space, purifies it, and then delivers it to the indoor space. Air enters airflow distribution chamber 24 through inlets 2421 / 2422 and then flows to air purification chamber 23 . The air intake chamber 22 takes in the air purified from the air purification chamber 23 and sends it to the indoor space through the air outlets 221/222.

The third basic operation pattern is an operation pattern in which fresh air is introduced and internal circulation is performed at the same time. It sucks in air, purifies it, and then sends it to the indoor space. Outdoor air enters the airflow distribution chamber 24 through the fresh air vents 2411 / 2412 and then flows to the air purification chamber 23 . At the same time, room air enters the airflow distribution chamber 24 through the inlets 2421/2422 and flows to the air purification chamber 23 as well. The air intake chamber 22 takes in the air purified from the air purification chamber 23 and sends it to the indoor space through the air outlets 221/222.

Air purification and ventilation devices can also implement an exhaust operating pattern. Among them, the exhaust chamber 25 has a return air port 251 for communicating with the indoor space and exhaust ports 252a/252b for communicating with the outdoor space. When the exhaust fan 33 rotates, the air enters the exhaust chamber 25 through the return air port 251 and is then discharged to the outdoor space through the exhaust ports 252a/252b.

Each of the above three basic actuation patterns can be performed independently. The exhaust actuation pattern can be done individually. The exhaust actuation pattern can also be performed simultaneously with any one of the three basic actuation patterns.

The exhaust chamber 25 is installed separately. Exhaust chamber 25 does not communicate with airflow distribution chamber 24 , air purification chamber 23 , or intake chamber 22 . In the air cleaning and ventilating device, when exhausting air, the airflow of the exhaust air collides with the airflow in the airflow distribution chamber 24, the air purification chamber 23, or the air intake chamber 22, causing turbulence and turbulence in the airflow. never It does not interfere with the normal operation of the inner circulation operation pattern and the fresh wind introduction operation pattern.

When the air cleaning and ventilating device is used, the air cleaning and ventilating device is installed indoors, and the new air vents 2411/2412 and the exhaust vents 252a/252b are communicated with the outdoor space. The air purification and ventilation device has a fresh air introduction operation pattern, an internal circulation operation pattern, an operation pattern in which fresh air introduction and internal circulation are performed at the same time, and a single exhaust operation pattern, or an exhaust operation pattern and any one of the above operations. A combination with a pattern can be realized. Moreover, since the airflow paths for the exhaust gas are individually provided, there is no possibility that the airflow will collide with other airflow paths and cause disturbance or turbulence in the airflow. As can be seen, various operating patterns of air purification and ventilation devices can be matched and combined to effectively treat indoor air and improve indoor air quality. In addition, the air purification and ventilation device has a compact structure, reasonable layout and small volume.

The air purifying and ventilating device has a columnar structure throughout its profile. Specifically, the case 1 may be thick at one end and thin at the other end, thick in the middle and thin at both ends, or may have a cylindrical or prismatic structure, for example. The specific structure of the case 1 is determined according to the dimensions and shapes of the parts contained therein and the actual needs. As shown in FIGS. 2a, 2b, and 2c, the intake chamber 22, the air purification chamber 23, the airflow distribution chamber 24, and the exhaust chamber 25 are all provided within the case 1, and the case 1 are distributed in order from the first end to the second end of the . The overall columnar structure is easy to install and can also blend better with the interior space.

In order to accommodate the structural arrangement of the air purification and ventilation device, in a preferred embodiment, the air purification assembly 32 is a cylindrical filter mesh, as shown in Figures 2b and 2c. This allows the profile of the air purifying assembly 32 to better match the air purifying chamber 23, resulting in higher space utilization. If desired, the filter net may be distributed in layers above and below. The air purification chamber 23 achieves compression of air and acceleration of the airflow velocity, making it easier for the airflow to enter the intake fan 31 . A filter mesh is mounted within the air purification chamber to form an airflow passageway. The airflow uniformly enters the filter mesh of the air purification assembly 32 . The utilization rate of the filter net area is improved, and the purification efficiency is also improved. Also, the filter network may be provided with any one or a combination of modules of an early effect filter network module, a PM2.5 filtration module and an activated carbon filtration module. It is also possible to remove noxious gaseous substances in the air in indoor or outdoor spaces by placing some reactants in the filter mesh that can remove other contaminants such as formaldehyde.

2b and 2c, in a preferred embodiment, one end of air purifying chamber 23 communicates with intake chamber 22 and the other end of air purifying chamber 23 communicates with airflow distribution chamber 24 . The structure of such layout is compact and the volume of the air purification and ventilation device can be small. In order to facilitate communication of the air purification chamber 23 with the intake chamber 22 and the airflow distribution chamber 24, the upper end of the air purification chamber 23 is communicated with the intake chamber 22 and the lower end of the air purification chamber 23 is communicated with the airflow distribution chamber 24. can be done. After the air in the airflow distribution chamber 24 flows into the air purification chamber 23 and is purified by the purification device, it flows into the intake chamber 22 .

In addition, the case 1 includes an electrostatic precipitator module, a streamer energy module, an electric heat-supplying module, etc., for example, in a filter mesh housing chamber, in air flow distribution.

In order to facilitate the electrical supply or control of the electrical elements in the air purification and ventilation device, as shown in FIGS. 21 are further provided. The containment chamber 21 may be provided with other electrical control elements such as a power supply, a controller, and the like. Since the housing chamber 21 housing the electric control element is close to the display panel 139, wiring and communication from the housing chamber 21 to the display panel 139 are facilitated.

As can be seen with reference to FIGS. 1b and 2b, the return air port 251 is provided in the end face of the second end of the case 1. As shown in FIG. That is, the return air port 251 is provided on the end surface of the second end cap 12 .

As shown in FIGS. 1a, 1b and 2a, the fresh air inlets 2411/2412 and the air inlets 2421/2422 are exposed from the side walls of the case 1 in the airflow distribution chamber 24. FIG. Air outlets 221 / 222 are exposed from the sidewall of case 1 in intake chamber 22 . When fresh air is introduced from the outdoor space to the indoor space, the air in the outdoor space enters the airflow distribution chamber 24 through the fresh air outlets 2411/2412, flows upward into the air purification chamber 23, and is purified by the air purification assembly 32. , further upwards into the intake chamber 22 and finally into the interior space through the air outlets 221 / 222 in the side wall of the case 1 . When the air in the indoor space needs to be internally circulated and purified, the air in the indoor space enters the airflow distribution chamber 24 through the inlets 2421 / 2422 and then flows upward into the air purification chamber 23 to the air purification assembly 32 . After being purified by , it further upwardly enters the intake chamber 22 and finally returns to the interior space through the air outlets 221 / 222 in the side wall of the case 1 . As can be seen with reference to FIGS. 2b and 2b, the exhaust ports 252a/252b are exposed from the side walls of the case 1 at the exhaust chamber 25. FIG. The return air port 251 is provided on the end surface of the second end cap 12 . When it needs to be exhausted, the room air enters the exhaust chamber 25 through the end face of the second end cap 12 and is exhausted into the interior space through the exhaust ports 252a/252b in the side walls of the case 1 .

In an air purification and ventilation device, the airflow distribution chamber 24 can introduce air entering the fresh air vents 2411 / 2412 into the air purification chamber 23 . Also, the air entering through the inlets 2421 / 2422 can be introduced into the air cleaning chamber 23 . In order to realize this function, in a preferred embodiment, the case 1 is provided with an airflow distributor 14, as shown in FIGS. 2b and 2c. An airflow distribution chamber 24 is provided in the airflow distributor 14 . As shown in FIGS. 3a, 3b, 3c, 3d and 3e, the airflow distribution chamber 24 includes a fresh air partition chamber 241 and a suction partition chamber 242. As shown in FIGS. There is a partition wall 141 between the fresh air partition chamber 241 and the suction partition chamber 242 . The new wind partition chamber 241 communicates with the air cleaning chamber 23 . A communication port 2413 is provided in the partition wall 141 . A communication port 2413 communicates between the fresh air partition chamber 241 and the suction partition chamber 242 .

The suction ports 2421 / 2422 are provided in the side walls of the suction partition chamber 242 . The upper end of the new wind partition chamber 241 communicates with the air purification chamber 23 . The upper end of the suction partition chamber 242 does not communicate with the air cleaning chamber 23 . Air entering the fresh air partition chamber 241 through the fresh air ports 2411/2412 can enter the air purification chamber 23 directly. The air entering the suction partitioned chamber 242 through the suction ports 2421 / 2422 can enter the fresh air partitioned chamber 241 through the communication port 2413 and then enter the air purification chamber 23 . In order to control the entry of air into the airflow distribution chamber 24, the side wall of the fresh air partition chamber 241 is provided with two fresh air vents, as shown in FIGS. 3a, 3b, 3d and 3e. there is One of them is the first new air outlet 2411 and the other is the second new air outlet 2412 .

The first valve plate 41 is driven by the first drive mechanism 42 to close the first new air port 2411 , close the communication port 2413 , and between the first new air port 2411 and the communication port 2413 . You can move to each of the states located in . A second valve plate 43 is provided at the second fresh air port 2412 . The second valve plate 43 is driven by the second drive mechanism 44 to close or open the second fresh air port 2412 . By controlling the first valve plate 41 and the second valve plate 43, it is possible to switch the operation pattern of the air purification and ventilation device. Both the first drive mechanism 42 and the second drive mechanism 44 may be rotary motors. The control device controls the rotation angle of the rotary shaft of the rotary motor, thereby controlling the opening degree of the first valve plate 41 or the second valve plate, thereby controlling the magnitude of the air flow rate. .

Another preferred embodiment of the airflow distributor 14 is shown in Figure 3f. The communication port 2413 includes a first communication port 2413a and a second communication port 2413b provided in the partition wall.

The first communication port 2413a approaches the first valve plate 41 side, and the second communication port 2413b approaches the second valve plate 43 side. Since the structures of the left and right sides of the airflow distributor 14 are basically symmetrical structures, manufacturing and mounting are easy. Moreover, since both the first valve plate 41 and the second valve plate 43 rotate inside the fresh air partition chamber, they do not protrude from the outer wall of the airflow distributor. Therefore, the first valve plate 41 and the second valve plate 43 do not interfere with parts or walls on the exterior of the flow distributor. Also, since the first valve plate 41 and the second valve plate 43 move in the same manner, when the second new air inlet 2412 is closed and fresh air is sucked through the first new air outlet 2411 Also, when the first new air outlet 2411 is closed and fresh air is taken in via the second new air outlet 2412, the indoor air treatment device has a fresh air introduction operation pattern, an inner circulation operation pattern, Since the logic of control for the operating pattern in which fresh wind introduction and internal circulation are simultaneously performed is similar, such a control method is simpler and less likely to cause user confusion during use.

In order to detect the concentration of PM2.5 in the air in the indoor space and the outdoor space, an outdoor PM2.5 detection sensor is installed in the fresh air partition chamber 241, and an indoor PM2.5 detection sensor is installed in the suction partition chamber 242. can do. Both the outdoor PM2.5 detection sensor and the indoor PM2.5 detection sensor are connected to the control device. Based on the data detected by the outdoor PM2.5 detection sensor and the indoor PM2.5 detection sensor, the control device controls the movement of the first drive mechanism 42, the second drive mechanism 44, the intake fan, and the exhaust fan 33. can be controlled, thereby regulating the room air.

Both the first air outlet 221 and the second air outlet 222 introduce air into the indoor space. A turbo fan may be used as the intake fan 31 so that the air currents sent out from the first air outlet 221 and the second air outlet 222 form a surrounding air current. As shown in FIG. 1c, the airflow emitted from the first air outlet 221 flows to one side wall, and the airflow emitted from the second air outlet 222 flows to the vertical wall on the other side, resulting in two streams joins along the wall from the opposite direction and is surrounded. Such fluid flow allows the airflow to be distributed more evenly throughout the room and not blown out onto the human body, thereby significantly improving the comfort of the human body.

(3) Modifications (3-1) Modifications of Air Purification Chamber Air purification chambers shown in FIGS. 5a, 5b, and 5c are provided in place of the air purification chamber 23 provided with the air purification assembly 32 described above. may be adopted. This air purification chamber is provided with an air filter 21A. Air filter 21A includes filter cartridge 211A. Filter cartridge 211A has an inner chamber 2111 . Filter cartridge 211A has a first end 2112 and a second end 2113 . An airflow outlet 2114 is provided at the second end 2113 of the filter cartridge 211A. One side of the central axis 2112c of the first end 2112 of the filter cartridge 211A is the windward side (windward side is the diameter EF of the first end 2112 of the filter cartridge 211A, see FIGS. 5c and 6a). and the diameter CD of the second end 2113, and the side closer to the position into which the airflow flows). The other side of the central axis 2112c of the first end 2112 of the filter cartridge 211A is the leeward side (leeward side is the diameter EF of the first end 2112 of the filter cartridge 211A, see FIGS. 5c and 6a). and the diameter CD of the second end 2113 and farther from the position into which the airflow flows). The space on one side of the filter cartridge 211A is the upwind space S24. The space on the other side of the filter cartridge 211A is the leeward space S25. The center O' of the second end 2113 of the filter cartridge 211A is near the upwind space S24 and is distanced from the central axis 2112c of the first end 2112 of the filter cartridge 211A. When filtering the air, the air passes through the side wall of the filter cartridge 211A on the side closer to the upwind space S24, enters the inner chamber 2111 of the filter cartridge 211A, and exits through the air outlet 2114 at the second end 2113.

As can be seen with reference to FIGS. 5c and 6b, when the air purifier is in use, air passes through the sidewall of the filter cartridge 211A on the side closer to the upwind space S24 and enters the inner chamber 2111 of the filter cartridge 211A. , out of the airflow outlet 2114 at the second end 2113 . One side of the central axis 2112c of the first end 2112 of the filter cartridge 211A is the windward side, and the other side is the leeward side. A space on one side of the filter cartridge 211A is an upwind space S24. The space on the other side of the filter cartridge 211A is the leeward space S25. The center of the second end 2113 of the filter cartridge 211A is near the upwind space S24 and is distant from the central axis 2112c of the first end 2112 of the filter cartridge 211A. As a result, the filter cartridge 211A inclines toward the windward space S24 and moves away from the leeward space S25. Then, the area of the filter cartridge 211A on the side facing the windward space S24 increases, the effective utilization area of the air filter 21A increases, the air filter 21A is fully utilized, and the filtration efficiency improves. As a result, even the short air filter 21A has a high filtering efficiency, so there is no need to increase the size of the filter in order to increase the filtering efficiency, which is advantageous for reducing the volume of the entire machine.

As shown in FIGS. 5c and 6b, the sidewall facing the windward space S24 of the filter cartridge 211A is the windward surface 2115. FIG. A side wall facing the leeward space S25 of the filter cartridge 211A is a leeward surface 2116 . The windward surface 2115 faces the direction in which the airflow enters. Most of the airflow enters the inner chamber 2111 of the filter cartridge 211A from the windward surface 2115 because the windward surface 2115 is the closest distance to where the airflow enters. A second end 2113 of the filter cartridge 211A slopes toward the upwind space S24. As a result, the area of the windward surface 2115 of the filter cartridge 211A is increased, and the filtration area of the filter cartridge 211A is increased, so that the filter cartridge 211A is fully utilized. As shown in Figures 5c and 6b, less airflow enters the inner chamber 2111 of the filter cartridge 211A from the leeward surface 2116 due to the greater distance of the leeward surface 2116 to the location of the airflow entry. Therefore, the area of the leeward surface 2116 is smaller than the area of the windward surface 2115 . Usage requirements can be met without increasing the area of the leeward surface 2116 .

As can be seen with reference to Figures 5a, 5b and 5c, both the first end 2112 and the second end 2113 of the filter cartridge 211A are circular. As shown in Figures 5c and 6a, the first end 2112 and the second end 2113 of the filter cartridge 211A are provided on different axes. The diameter of first end 2112 of filter cartridge 211A is smaller than the diameter of second end 2113 . The center of the second end 2113 of filter cartridge 211A is biased toward the windward surface 2115 . As shown in FIG. 6a, the edge of the second end 2113 of the filter cartridge 211A includes a windward arc 2113a near the windward space S24 and a leeward arc 2113b near the leeward space S25. The boundary points between the windward arc 2113a and the leeward arc 2113b are points C and D. The midpoint of the windward arc 2113a is the B point. The midpoint of the leeward arc 2113b is the A point. Point O in FIG. 6a is the center of the first end 2112 of the filter cartridge 211A. A central axis 2112c of the first end 2112 of the filter cartridge 211A passes through the O point. The distance between the midpoint A of the leeward arc 2113b and the central axis 2112c of the first end 2112 of the filter cartridge 211A is d1. The distance between the midpoint B of the windward arc 2113a and the central axis 2112c of the first end 2112 of the filter cartridge 211A is d2. d2>d1. Since d2>d1, the second end 2113 of the filter cartridge 211A is inclined toward the upwind space S24. This increases the area of the windward surface 2115 of the filter cartridge 211A. As shown in FIG. 5c, the connecting line between the center O of the first end 2112 and the center O' of the second end 2113 of the filter cartridge 211A is OO'. There is an angle between the connecting line OO' and the central axis 2112c of the first end 2112 of the filter cartridge 211A, which is inclined toward the upwind space S24. The tie OO' lies in the plane of the diameter EF of the first end 2112 and the diameter CD of the second end 2113 of the filter cartridge 211A.

As shown in Figures 5a, 5b and 5c, the filter cartridge 211A presents an inclined frusto-conical shape. Also, the first end 2112 of the filter cartridge 211A may be provided to be closed. A circular sealing plate 212 is connected to the first end 2112 of the filter cartridge 211A, as shown in Figures 5a, 5b and 5c. An annular end plate 213 is connected to the second end 2113 of the filter cartridge 211A. The inner hole of the annular end plate 213 is the air outlet 2114 .

(3-2) Modification of Intake Chamber Instead of the intake chamber 22, an intake means 13A having an intake port 1311 for sucking air shown in FIGS. 7a, 7b, and 7c is adopted. good too. The suction port 1311 is provided with a guide cover 12A as a cover. A plurality of guide holes 1221 are provided in the guide cover 12A. An airflow passage 15 is formed between the guide cover 12A and the intake means 13A. When the suction port 1311 sucks air, a part of the air enters the suction port 1311 through the guide holes 1221 and the other part of the air enters the suction port 1311 through the airflow passage 15 .

In the indoor air processing device, a guide cover 12A is provided as a cover for the intake port 1311 of the intake means 13A. A plurality of guide holes 1221 are provided in the guide cover 12A. An airflow passage 15 is formed between the guide cover 12A and the intake means 13A. When the suction port 1311 sucks air, a part of the air enters the suction port 1311 through the guide holes 1221 and the other part of the air enters the suction port 1311 through the airflow passage 15 . Therefore, the airflow flows to different parts of the suction port 1311 via two paths. Then, the airflow can uniformly flow from the suction port 1311 to the suction means 13A of the indoor air treatment device. As a result, the airflow in the room becomes uniform, and the comfort of use for the user is improved. In addition, since the guide cover 12A is covered by the suction port 1311, the user cannot directly observe the internal structure of the indoor air treatment device through the suction port 1311, which improves the appearance of the product and reduces noise. reduced.
