Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a vertical air conditioning indoor unit. Background Art

[0002] The vertical air conditioner indoor unit includes a main body, the main body includes a first cavity arranged in the main body and a casing, the casing includes a heat exchange air inlet and a heat exchange air outlet arranged on the casing, wherein the heat exchange air inlet and the heat exchange air outlet are both connected to the first cavity. The main body also includes an indoor heat exchanger and a heat exchange fan, the indoor heat exchanger and the heat exchange fan are both arranged in the first cavity, the heat exchange fan is arranged on the front side of the indoor heat exchanger, and the rotation of the heat exchange fan causes indoor air to enter the first cavity from the indoor air inlet, and the indoor air entering the first cavity exchanges heat with the indoor heat exchanger and then flows out from the heat exchange air outlet. In order to improve the air quality of the indoor environment, a fresh air module can be added to the traditional air conditioner indoor unit, and the fresh air module can be used to introduce outdoor fresh air into the room, thereby realizing the renewal of indoor air, thereby improving the quality of the indoor environment.

[0003] For a vertical air conditioner indoor unit, in order to facilitate the introduction of fresh air and the arrangement of the components of the air conditioner indoor unit, a fresh air module is generally arranged at the bottom of the air conditioner indoor unit, a second cavity is arranged below the first cavity, a fresh air volute is arranged in the second cavity, and a fresh air inlet for introducing outdoor fresh air is opened on the rear side of the casing. The fresh air module usually includes a fresh air fan and a fresh air volute, a fan cavity is defined inside the fresh air volute, a fresh air fan of the fresh air fan is arranged in the fan cavity, the fan cavity is connected to the fresh air inlet, and the rotation of the fresh air fan causes the outdoor fresh air to be introduced into the room from the fresh air inlet through the fan cavity. In order to ensure the quality of the fresh air introduced into the room, a purification device for purifying the outdoor fresh air is usually installed, and the purification device is usually installed between the fresh air inlet and the fresh air volute.

[0004] The purification device is usually inserted into the casing from top to bottom. Since the rear side of the air conditioner indoor unit faces the wall, it is inconvenient to install and disassemble the purification device. Although in the prior art, there are also some air conditioner indoor units that open the insertion port of the purification device on the side of the casing away from the wall, the purification device is generally inserted into the fresh air module in the horizontal direction. This horizontal pull-out method requires a larger space on the outer side of the vertical air conditioner indoor unit. When the space on the outer side of the vertical air conditioner indoor unit is smaller, it makes it difficult to disassemble the purification device, which seriously affects the feasibility of installing the purification device. Therefore, this horizontal insertion method is not suitable for use in the case where the installation space on the outer side of the vertical air conditioner indoor unit is small; the purification device is installed in the second cavity, which will inevitably make the purification device occupy a larger space in the second cavity. In order to avoid making the overall size of the lower part of the casing larger, the structure and installation position of the purification module can be adjusted, but it will affect the purification area of ​​the purification device; and the lack of guiding and limiting structures during the insertion of the purification device makes it difficult to install the purification device and the final position is not easy to define.

[0005] Moreover, the setting position of the fresh air inlet, the setting position of the purification insertion port and the position where the purification device is installed in the second cavity have a great influence on the fresh air volume and the fresh air penetration efficiency. When the setting position of the fresh air inlet is not coordinated with the setting position of the purification insertion port, it often causes changes in the structural length and thickness of the purification device, seriously affecting the size of the second cavity, affecting the overall size of the casing, and reducing the fresh air volume, reducing the fresh air penetration efficiency, and affecting the normal operation of the purification device and the fresh air module.

[0006] Therefore, the present application proposes a vertical air-conditioning indoor unit. Summary of the invention

[0081] (2) On the basis of the foregoing (1), further, since point B is set in front of point A and the connection line between 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, and based on the thickness space advantage of the vertical air conditioner indoor unit in the front-back direction, set L21 < L29 < L23 and 5 mm ≤ L23 - L21 ≤ 50 mm, 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.

[0082] (3) On the basis of the foregoing (1) and (2), further, since the fresh air inlet and the first purification insertion port are set on the same side, it can make the connection line between the center of the fresh air inlet and the center of the fresh air fan be approximately perpendicular to the windward surface of the first filter screen, thereby improving the air inlet efficiency of the fresh air from the fresh air inlet passing through the windward surface of the first filter screen.

[0314] In the present application:

[0315] (1) Setting point B in front of point A and setting an included angle D1 between the length direction of the first filter element and the width direction of the main body can both enable the first filter element to always tilt forward and sideward around point B during or after being inserted into the main body. Among them, when the first purification device is 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 of the first purification device, the user can be in front of or on the side of the main body, push the first filter element along the rear side of the main body or pull it out along the front side of the main body, and follow the user's operation action to install the first filter element in the second cavity. The inclined placement of the first filter element can effectively shorten the operation stroke of pushing or pulling, reduce the space occupied by the first filter element during the pushing or pulling process, and improve the operation efficiency of pushing or pulling; moreover, during the installation and disassembly of the first purification device, the first purification device can always be centered around the first purification insertion port and be installed or disassembled along an arc trajectory on the side front of the indoor unit main body. Therefore, the space occupied on the side away from the main body at the first purification insertion port is relatively small, which can avoid the problem of difficult disassembly caused by installing the vertical air conditioner indoor unit near the wall.

[0316] (2) On the basis of the above (1), further, due to setting point B in front of point A and setting an included angle D1 between the length direction of the first filter element and 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, considering the thickness space advantage of the vertical air conditioner indoor unit in the front-back direction, set L21 < L22 < L23 and 5mm ≤ L23 - L21 ≤ 50mm, 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 corresponding to the fresh air inlet, and improve the storage capacity of the fresh air introduced into the space.

[0317] (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, it can make the connection line between the center of the fresh air inlet and the center of the fresh air fan approximately perpendicular to the windward surface of the first filter screen, thus improving the air intake efficiency of the fresh air from the fresh air inlet passing through the windward surface of the first filter screen.

[0318] In some embodiments of the present application, the first purification insertion port is formed on the casing and 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.

[0319] The windward surface of the first filter element is an arc surface.

[0320] After the first purification device is inserted to the preset position, in the front-back direction of the main body, point B is in front of point A.

[0321] Define the plane passing through the rear endpoint of the casing and extending in the height and width directions of the main body as the second plane.

[0322] The midpoint of the line connecting point A and point B is point H.

[0323] 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 5mm < L23 - L21 ≤ 50mm.

[0324] In some embodiments of the present application, the first purification insertion opening 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 opening.

[0325] The windward surface of the first filter element is an arc surface.

[0326] 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.

[0328] In the present application: (1)

[0330] Setting point B in front of point A and setting an angle D4 between the line connecting point A and point B and the width direction of the main body can both make the first filter element always tilt forward and sideward around point B during or after being inserted into the main body. Among them, when the first purification device is inserted backward and to the side away from the first purification insertion opening in the width direction of the main body, during the installation and disassembly of the first purification device, the user can be in front of or on the side of the main body, push the first filter element toward the rear side of the main body or pull it toward the front side of the main body, following the trend of the user's operation action to install the first filter element in the second cavity. The inclined placement of the first filter element can effectively shorten the operation stroke of pushing or pulling, reduce the space occupied by the first filter element during the process of pushing or pulling, and improve the operation efficiency of pushing or pulling; and, during the installation and disassembly of the first purification device, the first purification device can always be centered around the first purification insertion opening and be installed or disassembled along an arc trajectory in the front side of the indoor unit main body. Therefore, the space occupied on the side away from the main body at the first purification insertion opening is relatively small, and it can avoid the problem of difficult disassembly caused by installing the vertical air conditioner indoor unit near the wall.

[0331] (2) On the basis of the foregoing (1), further, since point B is set in front of point A and the connection line between 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, and based on the thickness space advantage of the vertical air conditioner indoor unit in the front-rear direction, set L21 < L29 < L23 and 5 mm ≤ L23 - L21 ≤ 50 mm, which limits the minimum value of the difference between the two ends of the first filter element in the front-rear 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.

[0332] (3) On the basis of the foregoing (1) and (2), further, since the fresh air inlet and the first purification insertion port are set on the same side, it can make the connection line between 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, thus improving the air inlet efficiency of the fresh air from the fresh air inlet passing through the windward surface of the first filter screen.

[0336] In some embodiments of the present application, the windward surface of the first filter element includes a first windward surface contour line parallel to the horizontal plane.

[0337] The center of the fresh air inlet is point E, and the center of the fresh air fan is point F; in the width direction of the main body, the distance between point E and point F is L25; where 10 mm ≤ L25 ≤ 50 mm.

[0338] The intersection point of the connection line between point E and point F and the windward surface of the first filter element is point G.

[0339] In the width direction of the main body, the distance between point G and point C is L26, where 5 mm ≤ L26 ≤ 50 mm; it can make the connection line between 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, can improve the air inlet efficiency of the fresh air, and make the air inlet area of the fresh air as close as possible to the middle of the first filter element, so as to make full use of the air inlet area of the first filter element.

[0340] In some embodiments of the present application, the center of the fresh air inlet is point E, and the center of the fresh air fan is point F.

[0341] The projections of the line connecting point E and point F and the line connecting point A and point B on the same horizontal plane are set at an angle D5, wherein 70°≤D5≤110°, which can make the line connecting the center of the fresh air inlet and the center of the fresh air fan close to perpendicular to the windward surface of the first filter, thereby improving the fresh air intake efficiency.

[0346] In the width direction of the main body, the distance between point I and point H is L30, where 5mm≤L30≤50mm.

[0347] The line connecting 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, thereby improving the fresh air intake efficiency and making the fresh air intake area as close as possible to the middle of the first filter element, thereby making full use of the air intake area of ​​the first filter element.

[0349] In some embodiments of the present application, in the width direction of the main body, the distance between the center of the fresh air inlet and the center of the main body is L28, where 5mm≤L28≤50mm.

[0350] The center of the fresh air inlet and the center of the fresh air fan are all at a certain distance from the center of the main body, so that the fresh air inlet and the purification air inlet can be on the same side and the main body can be prevented from being too large in the width direction.
