Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to a vertical air conditioning indoor unit. Background Technology

[0002] A vertical air conditioner indoor unit includes a main body, which comprises a first cavity and a casing. The casing includes a heat exchange air inlet and a heat exchange air outlet, both of which communicate with the first cavity. The main body also includes an indoor heat exchanger and a heat exchange fan, both located within the first cavity. The heat exchange fan is positioned in front of the indoor heat exchanger. The rotation of the heat exchange fan causes indoor air to enter the first cavity through the indoor air inlet. After exchanging heat with the indoor heat exchanger, the indoor air flows out through the heat exchange air outlet. To improve indoor air quality, a fresh air module can be added to a traditional air conditioner indoor unit. This module introduces fresh outdoor air into the room, thus refreshing the indoor air and improving indoor environmental quality.

[0003] For vertical air conditioner indoor units, to facilitate the introduction of fresh air and the arrangement of components, the fresh air module is typically located at the bottom of the indoor unit. A second chamber is located below the first chamber, and the fresh air volute is housed within the second chamber. The fresh air inlet for introducing outdoor fresh air is located at the rear of the unit casing. The fresh air module usually includes a fresh air fan and a fresh air volute. The fresh air volute internally defines a fan chamber, where the fresh air fan is located. The fan chamber is connected to the fresh air inlet, and the rotation of the fresh air fan draws outdoor fresh air into the room through the fan chamber and the fresh air inlet. To ensure the quality of the introduced indoor fresh air, a purification device for purifying the outdoor fresh air is usually installed. This purification device is typically installed between the fresh air inlet and the fresh air volute.

[0004] The purification device is typically inserted into the casing from top to bottom. Since the rear of the indoor unit faces the wall, installing and removing the purification device is inconvenient. Although some existing indoor units have the purification device's insertion port on the side of the casing away from the wall, the purification device is generally inserted horizontally into the fresh air module. This horizontal pull-out method requires a large space on the outer side of the vertical indoor unit. When this space is limited, removing the purification device becomes difficult, severely impacting the feasibility of installation. Therefore, this horizontal insertion method is unsuitable for situations where the installation space on the outer side of the vertical indoor unit is limited. Installing the purification device in the second cavity inevitably occupies a significant amount of space within that cavity. To avoid making the overall lower part of the casing too large, the structure and installation position of the purification module can be adjusted, but this will affect the purification area. Furthermore, the lack of guiding and restraining structures during insertion makes the purification device difficult to install and its final position uncertain.

[0005] Furthermore, the location of the fresh air inlet, the location of the purification inlet, and the position of the purification device installed in the second chamber all have a significant impact on the fresh air volume and fresh air transmission efficiency. When the locations of the fresh air inlet and the purification inlet are not coordinated, it often causes changes in the structural length and thickness of the purification device, which seriously affects the size of the second chamber, the overall size of the casing, and reduces the fresh air volume and fresh air transmission efficiency, thus affecting the normal operation of the purification device and the fresh air module.

[0006] Therefore, this application proposes a vertical air conditioner indoor unit. Summary of the Invention

[0092] A fresh air hood, which is arranged in the second cavity and behind the fresh air volute;

[0094] The first purification device is inserted into the fresh air hood and is used for purifying the fresh air entering the fan cavity through the fresh air hood;

[0095] Define a horizontally arranged straight line perpendicular to the front and back direction of the main body as the first straight line;

[0096] A first purification guide rail is formed on the fresh air hood and is used to define the insertion trajectory of the first purification device;

[0097] The first purification device is inserted into the first purification guide rail through the first purification insertion port or pulled out from the first purification guide rail.

[0098] The first purification guide rail includes:

[0099] A first guide rail, wherein the first purification device is located in front of the first guide rail; the first guide rail includes:

[0100] An insertion segment, including an insertion plane located on its front side;

[0101] A guide section is located on the side of the insertion section away from the first purification insertion port and on the rear side of the front end of the insertion section. The guide section includes a guide plane disposed on its front side.

[0102] The first limiting segment is located on the side of the guide segment away from the insertion segment and its front end is located in front of the guide segment. The first limiting segment includes a first limiting plane disposed on its front side.

[0103] The insertion plane, the guide plane, and the first limiting plane define the insertion trajectory of the first purification device;

[0104] The insertion plane includes an insertion contour line parallel to the horizontal plane. The projection of the straight line containing the insertion contour line onto the first straight line on the same horizontal plane forms a first angle, and the first angle is an acute angle.

[0105] The guide plane includes a guide contour line parallel to the horizontal plane. The projection of the straight line containing the guide contour line and the straight line containing the insertion contour line on the same horizontal plane forms a second angle. The second angle is an obtuse angle and the opening direction is towards the first purification device.

[0106] The first limiting plane includes a first limiting contour line parallel to the horizontal plane. The projection of the straight line containing the first limiting contour line and the straight line containing the guide contour line on the same horizontal plane forms a third angle. The third angle is an obtuse angle and the opening direction is towards the first purification device.

[0107] According to embodiments of this disclosure,

[0108] The windward surface of the first filter element includes a first windward surface outline that is parallel to the horizontal plane.

[0109] The center of the fresh air inlet is point E, and the center of the fresh air fan is point F;

[0111] According to embodiments of this disclosure,

[0112] The center of the fresh air inlet is point E, and the center of the fresh air fan is point F;

[0113] The projection of the line connecting points E and F onto the line connecting points A and B on the same horizontal plane forms an angle D5, where 70°≤D5≤110°.

[0114] According to embodiments of this disclosure,

[0115] The center of the fresh air inlet is point E, and the center of the fresh air fan is point F;

[0116] In the width direction of the main body, the distance between point E and point F is L25; where 10mm≤L25≤50mm;

[0117] The intersection of the line connecting points E and F with the windward side of the first filter element is point G.

[0118] In the width direction of the main body, the distance between point G and point C is L26, where 5mm≤L26≤50mm.

[0119] Beneficial effects:

[0120] (1) Setting point B in front of point A and setting the length direction of the first filter element to form an angle D1 with the width direction of the main body, and setting point B in front of point A and setting the line connecting point A and point B to form an angle D4 with the width direction of the main body, both ensure that the first filter element can always maintain a forward and sideways tilt around point B during insertion into the main body or after insertion. Specifically, inserting the first purification device backward and away from the first purification insertion port in the width direction of the main body, during the installation and removal of the first purification device, the user can be positioned in front of or to the side of the main body, pushing the first filter element towards the rear of the main body or towards the main body. Pulling out from the front allows the first filter element to be installed in the second cavity following the user's operating action. The first filter element is placed at an angle, which effectively shortens the pushing or pulling operation stroke, reduces the space occupied by the first filter element during the pushing or pulling process, and improves the efficiency of the pushing or pulling operation. Furthermore, during the installation and disassembly of the first purification device, the first purification device can always be installed or disassembled around the first purification insertion port in an arc-shaped trajectory on the front side of the indoor unit body. Therefore, the space occupied by the first purification insertion port and the side away from the main body is relatively small, which can avoid the problem of difficult disassembly caused by the vertical air conditioner indoor unit being installed near the wall.

[0121] (2) On the basis of the above (1), further, since point B is set in front of point A, the length direction of the first filter element forms an angle D1 with the width direction of the main body, and point B is set in front of point A and the line connecting point A and point B forms an angle D4 with the width direction of the main body, the first filter element is inclined after being inserted into the main body. On the basis of the inclined setting of the first filter element, taking advantage of the thickness space in the front-back direction of the vertical air conditioner indoor unit, L21 < L22 < L23 and 5 mm ≤ L23 - L21 ≤ 50 mm are set, and L21 < L29 < L23 and 5 mm ≤ L23 - L21 ≤ 50 mm are set, which limits the minimum value of the difference between the two ends of the first filter element in the front-back direction of the main body, so as to relatively increase the space at the rear of the first filter element and corresponding to the fresh air inlet, and improve the storage capacity of the fresh air introduced into the space.

[0122] (3) On the basis of the above (1) and (2), further, since the fresh air inlet and the first purification insertion port are set on the same side, the connection line between the center of the fresh air inlet and the center of the fresh air fan can be made close to perpendicular to the windward surface of the first filter, thus improving the air inlet efficiency of the fresh air from the fresh air inlet passing through the windward surface of the first filter.

[0170] This application discloses a vertical air conditioner indoor unit, as described below. Figures 1-31 Describe the indoor unit of a floor-standing air conditioner.

[0171] The indoor unit of a vertical air conditioner is a component of an air conditioner, which also includes the outdoor unit.

[0172] refer to Figure 1 and Figure 4 The indoor unit of the vertical air conditioner includes a main body 100, which includes a casing 1, an indoor heat exchanger 21, and a heat exchange fan 22.

[0173] The main body has a top and a bottom, with the height from the top to the bottom of the main body being the height direction. The main body also has a width direction, with the width from one side to the other being the width direction. The main body has a front and a rear side positioned opposite each other, with the side of the main body facing the user being the front side, and the distance from the front side to the rear side being the front-rear direction.

[0174] refer to Figure 4 and Figure 6 The main body includes at least a first cavity 131 and a second cavity 132 located within the main body, wherein the first cavity is located above the second cavity.

[0175] refer to Figures 1-4 The casing has a heat exchange air inlet 141, a heat exchange air outlet 1421 and a fresh air inlet 143, wherein the heat exchange air inlet is connected to the first cavity, the heat exchange air outlet is connected to the first cavity, and the fresh air inlet is connected to the second cavity.

[0176] The heat exchange air inlet is located at the rear of the main body, and the heat exchange air outlet is located at the front of the main body. The fresh air inlet is located at the rear of the main body.

[0177] An indoor heat exchanger is located in the first chamber and is used to exchange heat with the indoor air entering the first chamber.

[0178] The heat exchange fan is located in the first chamber, in front of the indoor heat exchanger, and is used to provide power for the flow of indoor air.

[0179] The rotation of the heat exchange fan causes indoor air to enter the first chamber through the heat exchange inlet and exchange heat with the indoor heat exchanger. The indoor air after heat exchange is discharged from the first chamber through the heat exchange outlet.

[0180] An air conditioner outdoor unit includes the outdoor unit casing, the outdoor heat exchanger, and the outdoor fan.

[0181] The outdoor unit casing has an outdoor housing space, in which the outdoor fan and outdoor heat exchanger are located.

[0182] The outdoor unit casing is equipped with an outdoor air inlet and an outdoor air outlet, both of which are connected to the outdoor enclosure. The outdoor air inlet is used to introduce outdoor air into the outdoor enclosure, and the outdoor air outlet is used to exhaust air from the outdoor enclosure to the outside.

[0183] The rotation of the outdoor fan causes outdoor air to enter the outdoor enclosure through the outdoor air inlet and exchange heat with the outdoor heat exchanger. After heat exchange, the outdoor air flows out of the outdoor enclosure through the outdoor air outlet.

[0184] An air conditioner also includes a compressor and a throttling device, wherein the throttling device is used to limit airflow. The compressor is located in the outdoor enclosure, and the throttling device is also located in the outdoor enclosure.

[0185] Air conditioners execute a refrigeration cycle using a compressor, condenser, throttling device, and evaporator. The refrigeration cycle involves a series of processes including compression, condensation, expansion, and evaporation, supplying refrigerant to the conditioned and heat-exchanged air.

[0186] The compressor compresses the refrigerant gas in a low-temperature, low-pressure state and discharges it in a high-temperature, high-pressure state.

[0187] The discharged refrigerant gas flows into the condenser.

[0188] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0189] The throttling device causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand into a low-pressure liquid refrigerant.

[0190] The evaporator evaporates the refrigerant that expands in the throttling device and returns the refrigerant gas, which is in a low-temperature and low-pressure state, to the compressor.

[0191] An evaporator achieves a cooling effect by exchanging heat with the material being cooled using the latent heat of refrigerant evaporation. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0192] In the indoor heat exchanger and the outdoor heat exchanger, one is a condenser and the other is an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in heating mode. When the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in cooling mode.

[0197] refer to Figure 3 The fan chamber can be connected to the heat exchange outlet. The rotation of the fresh air fan allows outdoor fresh air to enter the casing through the fresh air inlet, and then flows through the fan chamber to the room through the heat exchange outlet. Alternatively, a fresh air outlet 1422 is formed on the casing, which is connected to the fan chamber. The rotation of the fresh air fan allows outdoor fresh air to enter the casing through the fresh air inlet, and then flows through the fan chamber to the room through the fresh air outlet.

[0212] Specifically, looking down at the first included angle, the projection corresponding to the first straight line is rotated clockwise around the vertex of the first included angle by the angle of the first included angle and then coincides with the projection corresponding to the inserted contour line.

[0213] Furthermore, the first included angle α can be any value greater than 0° and less than 80°. Furthermore, the first included angle α can be any value between 20° and 70°.

This first angle is acute and serves as a guide for the first purification device, facilitating insertion into the air conditioner housing from the front to the rear, avoiding the difficulty in insertion caused by the limited insertion stroke on the side of the air conditioner. The first guide rail also includes a guide section and a first limiting section, as well as a guide contour line, an insertion contour line, and an angle between the first limiting contour line and the guide contour line. This allows the guide section and the limiting section to guide and limit the first purification device, enabling it to be inserted into the main body along the guide section and the limiting section.

[0293] Specifically, looking down at the twelfth included angle, the projection corresponding to the third limiting contour line coincides with the projection corresponding to the first limiting contour line after rotating clockwise by the angle of the twelfth included angle around the vertex of the twelfth included angle.

[0294] When the projections of the straight lines where the third limiting contour line and the first limiting contour line are located on the same horizontal plane are parallel, the third limiting plane and the first limiting plane are coplanar or parallel and non-coplanar.

The straight line where the first windward surface contour line is located is arranged at a fourth included angle d with the projection on the same horizontal plane as the first straight line, and the fourth included angle is an acute angle, 0° < d < 15°, to avoid increasing the front and rear dimensions of the main body due to too large an angle.

[0304] The first purification device includes a purification first end and a purification second end that are oppositely arranged. The purification first end is inserted into the first purification guide rail through the first purification insertion port or pulled out from the first purification guide rail.

The first length L3 is greater than the second length L4, that is, L3 > L4; and, the first length L3 is less than 1.3 times the second length L4, that is, L3 < 1.3L4.

[0307] Setting the straight line where the first windward surface contour line is located to form a fourth included angle with the projection of the first straight line on the same horizontal plane can increase the windward area and improve the air passing volume; setting L4 < L3 < 1.3L4 and setting the first length within a suitable range can avoid the first length being too small to meet the needs of the fresh air volute and avoid overly increasing the overall size of the body.

[0354] In the present application:

[0355] (1) Setting point B in front of point A and setting an angle D1 between the length direction of the first filter element and the width direction of the main body can both make the first filter element inclined after being inserted into the main body, so that the space at the rear end of point B of the first filter element is larger. Inclining the first filter element in the second cavity is convenient for the installation and disassembly of the first purification device; among them, by inserting the first purification device backward and in the width direction of the main body away from the first purification insertion port, during the installation and disassembly process of the first purification device, the space occupied on the side of the first purification insertion port away from the main body is relatively small, which can avoid the problem of difficult disassembly caused by installing the indoor unit of the vertical air conditioner near the wall;

[0356] (2) Set point B to be in front of point A and set the included angle D1 between the length direction of the first filter element and the width direction of the main body, so that the first filter element is inclined after being inserted into the main body. On the basis of the inclined setting of the first filter element, set L21 < L22 < L23 and 5 mm ≤ L23 - L21 ≤ 50 mm. Based on the advantages of the vertical air conditioner indoor unit in the front-back direction, the minimum value of the difference between the two ends of the first filter element in the front-back direction of the main body is limited, so as to relatively increase the space at the rear of the first filter element and corresponding to the fresh air inlet, and improve the storage capacity of the fresh air introduced into the space;

[0357] (3) Set point B to be in front of point A and set the included angle D1 between the length direction of the first filter element and the width direction of the main body, so that the first filter element is inclined after being inserted into the main body. On the basis of the inclined setting of the first filter element, set the fresh air inlet and the first purification insertion port on the same side, so that the fresh air inlet is set at a position where the space between the fresh air inlet and the filter element is larger, and improve the storage capacity of the fresh air introduced into the space; Moreover, it can make the connection line between the center of the fresh air inlet and the center of the fresh air fan close to being perpendicular to the windward surface of the first filter screen, and improve the air inlet efficiency of the fresh air;

[0358] In some embodiments of the present application, the first purification insertion port is formed on the casing and is located on the side of the main body. And, in the width direction of the main body, the center of the fresh air inlet is located on the side of the center of the main body close to the first purification insertion port.

[0359] The windward surface of the first filter element is an arc surface.

[0360] After the first purification device is inserted into the preset position, in the front-back direction of the main body, point B is in front of point A.

[0361] Define the plane passing through the rear end point of the casing and extending along the height direction and width direction of the main body as the second plane.

[0362] The midpoint of the connection line between point A and point B is point H.

[0363] The distance from point A to the second plane is L21, the distance from point H to the second plane is L29, and the distance from point B to the second plane is L23; where, L21 < L29 < L23, and 5 mm < L23 - L21 ≤ 50 mm.

[0364] In some embodiments of the present application, the first purification insertion port is formed on the casing and is located on the side of the main body. And, in the width direction of the main body, the center of the fresh air inlet is located on the side of the center of the main body close to the first purification insertion port.

[0365] The windward surface of the first filter element is an arc surface.

[0366] The endpoint of the first end of the filter element is point A, and the endpoint of the second end of the filter element is point B; the midpoint of the line connecting point A and point B is point H.

[0367] After the first purification device is inserted to the preset position, the line connecting point A and point B is arranged at an angle D4 with the width direction of the main body, where 5° ≤ D4 ≤ 30°. L21 < L29 < L23, and 5mm < L23 - L21 ≤ 50mm.

[0368] In this application:

[0369] (1) Setting point B in front of point A and setting the line connecting point A and point B to have an angle D4 with the width direction of the main body can both make the first filter element tilt after being inserted into the main body, resulting in a larger space at the rear end of point B of the first filter element. Tilt the first filter element in the second cavity, which is convenient for the installation and disassembly of the first purification device; among them, the first purification device can be inserted backward and to the side away from the first purification insertion port in the width direction of the main body. During the installation and disassembly process of the first purification device, the space occupied on the side of the first purification insertion port away from the main body is relatively small, which can avoid the problem of difficult disassembly caused by installing the vertical air conditioner indoor unit near the wall;

[0370] (2) Setting point B in front of point A and setting the line connecting point A and point B to have an angle D4 with the width direction of the main body makes the first filter element tilt after being inserted into the main body. On the basis of the tilted first filter element, setting L21 < L29 < L23 and 0mm < L23 - L21 ≤ 50mm is based on the advantages of the vertical air conditioner indoor unit in the front-back direction, limiting the minimum value of the difference between the two ends of the first filter element in the front-back direction of the main body, so as to relatively increase the space at the rear of the first filter element and corresponding to the fresh air inlet, and improve the storage capacity of the fresh air introduced into the space;

[0371] (3) Setting point B in front of point A and setting the line connecting point A and point B to have an angle D4 with the width direction of the main body makes the first filter element tilt after being inserted into the main body. On the basis of the tilted first filter element, setting the fresh air inlet and the first purification insertion port on the same side makes the fresh air inlet be set at a position where the space between the fresh air inlet and the filter element is larger, improving the storage capacity of the fresh air introduced into the space; and it can make the line connecting the center of the fresh air inlet and the center of the fresh air fan be close to perpendicular to the windward surface of the first filter screen, improving the fresh air inlet efficiency.

[0372] In some embodiments of this application, the windward surface of the first filter element includes a first windward surface contour line parallel to the horizontal plane.

[0373] The center of the fresh air inlet is point E, and the center of the fresh air fan is point F.

[0374] When the windward surface of the first filter element is a plane, the line connecting points E and F is set at an angle D7 with the projection of the outline of the first windward surface on the same horizontal plane, wherein 70°≤D7≤110°. This makes the line connecting the center of the fresh air inlet and the center of the fresh air fan nearly perpendicular to the windward surface of the first filter, thereby improving the fresh air intake efficiency.

[0375] In some embodiments of this application, the windward side of the first filter element includes a first windward side profile line parallel to the horizontal plane.

[0376] The center of the fresh air inlet is point E, and the center of the fresh air fan is point F; the distance between point E and point F in the width direction of the main body is L25; where 10mm≤L25≤50mm.

[0377] Point G is the intersection of the line connecting points E and F with the windward side of the first filter element.

[0378] In the width direction of the main body, the distance between point G and point C is L26, where 5mm≤L26≤50mm; this makes the line connecting the center of the fresh air inlet and the center of the fresh air fan nearly perpendicular to the windward surface of the first filter, which can improve the fresh air intake efficiency and make the fresh air intake area as close as possible to the middle of the first filter element, so as to make full use of the air intake area of ​​the first filter element.

[0379] In some embodiments of this application, the center of the fresh air inlet is point E, and the center of the fresh air fan is point F.

[0380] The projection of the line connecting points E and F onto the line connecting points A and B on the same horizontal plane forms an angle D5, where 70°≤D5≤110°. This ensures that the line connecting the center of the fresh air inlet and the center of the fresh air fan is nearly perpendicular to the windward side of the first filter, thereby improving the fresh air intake efficiency.

[0381] The windward surface of the first filter element can be either flat or curved.

[0382] In some embodiments of this application, the center of the fresh air inlet is point E, and the center of the fresh air fan is point F.

[0383] In the width direction of the main body, the distance between points E and F is L25; where 10mm≤L25≤50mm; this staggered arrangement of points E and F allows for a more convenient setup when the first filter is tilted, ensuring that the line connecting the center of the fresh air inlet and the center of the fresh air fan is nearly perpendicular to the windward side of the first filter, thereby improving the fresh air intake efficiency.

[0384] The intersection of the line connecting points E and F with the line connecting points A and B is point I.

[0385] In the width direction of the main body, the distance between point I and point H is L30, where 5mm≤L30≤50mm.

[0386] This design ensures that the line connecting the center of the fresh air inlet and the center of the fresh air fan is nearly perpendicular to the windward surface of the first filter, thereby improving the fresh air intake efficiency. Furthermore, it ensures that the fresh air intake area is as close as possible to the center of the first filter element, thus making full use of the air intake area of ​​the first filter element.

[0387] In some embodiments of this application, in the width direction of the main body, the center of the fresh air fan is located on the side of the center of the main body close to the first purification inlet, and the distance between the center of the fresh air fan and the center of the main body is L27, wherein 5mm≤L27≤50mm.

[0388] In some embodiments of this application, the distance between the center of the fresh air inlet and the center of the main body in the width direction of the main body is L28, wherein 5mm≤L28≤50mm.

[0389] This design ensures that the center of the fresh air inlet and the center of the fresh air fan are at a certain distance from the center of the main body, enabling the fresh air inlet and the purification air inlet to be on the same side, while avoiding the main body being too large in width, making full use of the space inside the main body, and avoiding the overall size of the main body being too large.

[0390] In some embodiments of this application, the central axis of the fresh air inlet is set along the front-rear direction of the main body, and the rotation axis of the fresh air fan and the projection of the central axis of the fresh air inlet on the same horizontal plane are set at an angle D2, wherein 5°≤D2≤20°, so as to facilitate setting the line connecting the center of the fresh air inlet and the center of the fresh air fan to be close to perpendicular to the windward surface of the first filter.

[0391] In some embodiments of this application, the rotation axis of the fresh air fan passes through the fresh air inlet, which makes the line connecting the center of the fresh air inlet and the center of the fresh air fan nearly perpendicular to the windward surface of the first filter.

[0392] In some embodiments of this application, the fresh air volute includes a volute windward plane, and the outline of the volute windward plane parallel to the horizontal plane is the volute windward surface outline. The projections of the volute windward surface outline and the first windward surface outline on the same horizontal plane are set at an angle D3, wherein 5°≤D3≤20°, which can make better use of the space in the width direction of the main body.

[0393] In some embodiments of this application, the fresh air volute includes a volute windward plane, and the outline of the volute windward plane parallel to the horizontal plane is the volute windward surface outline. The volute windward surface outline is set at an angle D6 with the width direction of the main body, wherein 5°≤D6≤20°, which facilitates setting the volute windward surface to be parallel to the approximate extension direction of the first filter.

[0394] In some embodiments of this application, the housing is provided with a purification air inlet 144, which is connected to the second cavity.

[0395] The purification air inlet is located at the rear of the main body, on the side of the fresh air inlet away from the first purification insertion port.

[0396] The air intake is connected to the space inside the fresh air hood.

[0397] When the air inlet for purification is open and the air inlet for fresh air is closed, the fresh air fan rotates, causing indoor air to enter the casing through the air inlet for purification, and then flow into the room through the fresh air hood and fresh air chamber.

[0398] When the air inlet for purification is closed and the air inlet for fresh air is open, the fresh air fan rotates to allow outdoor fresh air to enter the casing through the fresh air inlet, and then flow into the room through the fresh air hood and fresh air chamber.

[0399] When the purification air inlet and the fresh air inlet are opened, the fresh air fan rotates, causing indoor air to enter the casing through the purification air inlet, and the fresh air fan drives outdoor fresh air to enter the casing through the fresh air inlet.
