The intake chamber 22 takes in the purified air from the air purifying chamber 23 and sends it to the indoor space from the blower ports 221/222.

Also, the air purification and ventilation device can realize the exhaust operation pattern. Among them, the exhaust chamber 25 has a return air port 251 for communicating with the indoor space and an exhaust port 252a / 252b for communicating with the outdoor space. When the exhaust fan 33 rotates, air enters the exhaust chamber 25 through the return air port 251, and is then exhausted to the outdoor space through the exhaust ports 252a/252b.

▽ Each of the above three basic operation patterns can be performed individually. The exhaust operation pattern can be performed individually. Further, the exhaust operation pattern can be performed at the same time as any one of the above three basic operation patterns.

(3) Modification example (3-1) Modification example of air purification chamber The air purification chamber shown in FIGS. 5a, 5b, and 5c is replaced with the air purification chamber 23 provided with the above air purification assembly 32. May be adopted. An air filter 21A is provided in this air purification chamber. The air filter 21A includes a filter cartridge 211A. The filter cartridge 211A has an inner chamber 2111. The 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 windward (the windward is the diameter EF of the first end 2112 of the filter cartridge 211A with reference to FIGS. 5c and 6a. And the diameter CD of the second end 2113 as a boundary, which means the side closer to the position where the air flow enters. The other side of the central axis 2112c of the first end 2112 of the filter cartridge 211A is the leeward side (the leeward side is the diameter EF of the first end 2112 of the filter cartridge 211A with reference to FIGS. 5c and 6a. And the diameter CD of the second end 2113 and the plane where the air flow is defined as a boundary. 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 close to the windward space S24 and is at a distance from the central axis 2112c of the first end 2112 of the filter cartridge 211A. When filtering 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 flows out from the airflow outlet 2114 at the second end 2113.

As can be seen with reference to FIGS. 5c and 6b, when using the air purifier, air passes through the side wall 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 air flow outlet 2114 of 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. 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 of the second end 2113 of the filter cartridge 211A is close to the upwind space S24 and is away from the central axis 2112c of the first end 2112 of the filter cartridge 211A. As a result, the filter cartridge 211A is inclined toward the upwind space S24 and separated from the downwind space S25. Then, the area of the filter cartridge 211A on the side toward the upwind space S24 increases, the effective 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 filtration efficiency, so that it is not necessary to increase the size of the filter in order to increase the filtration efficiency, which is advantageous for reducing the volume of the entire machine.

As shown in FIGS. 5c and 6b, the side wall of the filter cartridge 211A facing the windward space S24 is the windward surface 2115. The side wall of the filter cartridge 211A toward the leeward space S25 is the leeward lower surface 2116. The wind surface 2115 is directed in the direction in which the airflow enters. Since the distance of the wind surface 2115 to the position where the air flow enters is the shortest, most of the air flow enters the inner chamber 2111 of the filter cartridge 211A from the wind surface 2115. The second end 2113 of the filter cartridge 211A is inclined toward the upwind space S24. As a result, the area of the windward surface 2115 of the filter cartridge 211A is increased, the filtration area of the filter cartridge 211A is further increased, and the filter cartridge 211A is fully utilized. As shown in FIGS. 5c and 6b, since the distance of the wind surface 2116 to the position where the air flow enters is long, the air flow from the wind surface 2116 to the inner chamber 2111 of the filter cartridge 211A is small. Therefore, the area of the wind lower surface 2116 is smaller than the area of the wind upper surface 2115. Even if the area of the windward surface 2116 does not become large, it is possible to meet the usage requirement.

As can be seen by referring to FIGS. 5a, 5b, and 5c, the first end 2112 and the second end 2113 of the filter cartridge 211A are both circular. As shown in FIGS. 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 the first end 2112 of the filter cartridge 211A is smaller than the diameter of the second end 2113. The circular center of the second end 2113 of the filter cartridge 211A is biased to the wind surface 2115. As shown in FIG. 6a, the edge of the second end 2113 of the filter cartridge 211A includes an upwind arc 2113a close to the upwind space S24 and a leeward arc 2113b close to the leeward space S25. The boundary points between the upwind arc 2113a and the downwind arc 2113b are points C and D. The midpoint of the windward arc 2113a is point B. The midpoint of the leeward arc 2113b is point A. The point O in FIG. 6a is the center of the first end 2112 of the filter cartridge 211A. The central axis 2112c of the first end 2112 of the filter cartridge 211A passes through the point O. 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 upwind 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 windward space S24. As a result, the area of the wind surface 2115 of the filter cartridge 211A becomes large. 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 tie line OO′ and the central axis 2112c of the first end 2112 of the filter cartridge 211A, and the inclination is toward the windward space S24. The tie line OO' lies in the plane of 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 FIGS. 5a, 5b, and 5c, the filter cartridge 211A has an inclined truncated cone shape. Further, the first end 2112 of the filter cartridge 211A may be provided so as to be closed. As shown in FIGS. 5a, 5b, and 5c, a circular sealing plate 212 is connected to the first end 2112 of the filter cartridge 211A. 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 airflow outlet 2114.

(3-2) Modified Example of Intake Chamber In place of the above-mentioned intake chamber 22, an intake means 13A having an intake port 1311 for intake of air shown in FIGS. 7a, 7b, and 7c is adopted. May be good. The suction port 1311 is provided with a flow guide cover 12A as a cover. A plurality of flow guiding holes 1221 are provided in the flow guiding cover 12A. An airflow passage 15 is formed between the flow 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 via the flow guide hole 1221 and the other part of the air enters the suction port 1311 via the airflow passage 15.

In the indoor air treatment device, a flow guide cover 12A is provided as a cover at the suction port 1311 of the intake means 13A. A plurality of flow guiding holes 1221 are provided in the flow guiding cover 12A. An air flow passage 15 is formed between the flow guide cover 12A and the intake means 13A. When the suction port 1311 takes in air, a part of the air enters the suction port 1311 through the guide hole 1221, and the air of the other part enters the suction port 1311 through the air flow passage 15. Therefore, the airflows flow through the two paths to different portions of the suction port 1311. Then, the airflow can uniformly flow from the suction port 1311 to the intake means 13A of the indoor air treatment device. As a result, the airflow in the room becomes uniform, and the comfort of use by the user is improved. Further, since the flow guide cover 12A is covered by the suction port 1311, the user cannot directly observe the internal structure of the indoor air treatment device from the suction port 1311, which improves the aesthetic appearance of the product and also causes noise. It will be reduced.
