Fig. 1 is a schematic structural view of a part of the structure of an indoor unit of an air conditioner according to an embodiment of the present utility model, as shown in fig. 1, and referring to fig. 2 to 5, an embodiment of the present utility model provides an indoor unit of an air conditioner. The air conditioner indoor unit includes an air duct frame 100 and a heat exchanger 200.
The air duct frame 100 includes an air duct plate 110. The duct plate 110 is vertically disposed at one side of a duct of the air conditioner indoor unit.
Heat exchanger 200 includes a tube sheet 210, tube sheet 210 being fixedly attached to one lateral end of air duct plate 110.
The side of the duct plate 110 remote from the duct is fixedly connected with a plurality of protruding ribs 300 arranged at vertical intervals. In the horizontal direction, the raised ribs 300 are spaced apart from and adjacent to the tube sheet 210, and one end of the raised ribs 300 near the tube sheet 210 is higher than the other end.
In this embodiment, the air duct frame 100 is directly contacted with the heat exchanger 200, and in the operation process of the air conditioner, the temperature of the heat exchanger 200 is different from the room temperature, and the air duct frame 100 is directly contacted with the heat exchanger 200 to generate heat exchange, so that condensed water is easy to generate on the air duct frame 100. The protruding ribs 300 inclined towards the lower side far away from the heat exchanger 200 enable condensed water to be guided to one side far away from the heat exchanger 200, so that the situation that condensed water formed on the air duct frame 100 is accumulated on the heat exchanger 200 is avoided, the situation that the heat exchanger 200 fails due to excessive condensed water on the heat exchanger 200 is avoided, and the service life of the indoor unit of the air conditioner is prolonged.
The air duct frame 100 is easily deformed due to the influence of internal and external pressure, temperature change and other factors in the long-term use process, so that air leakage occurs between the air duct frame 100 and the heat exchanger 200. The protruding ribs 300 are designed on one side of the air duct plate 110 close to the tube plate 210, and play a role in strengthening the structural strength of the air duct frame 100, so that the air duct is not easy to deform, and the sealing effect between the air duct frame 100 and the heat exchanger 200 is improved.
In order to ensure the tightness between the air duct frame 100 and the heat exchanger 200 and the connection stability between the air duct frame 100 and the heat exchanger 200, a large number of sealing sheet metal parts are used for connecting between the air duct frame 100 and the heat exchanger 200 in the existing part of the indoor air conditioner. The use of the sealing sheet metal part not only increases the manufacturing cost of the indoor unit of the air conditioner, but also reduces the sealing effect due to improper installation or long-term use of the sealing sheet metal part. The air duct board 110 provided with the protruding ribs 300 replaces the function of part of the sealing sheet metal parts to a certain extent, so that the number of the sealing sheet metal parts is reduced, the cost of the air conditioner indoor unit is reduced, and the maintenance and the service work of the air conditioner indoor unit are simplified.
In some embodiments of the present utility model, as shown in fig. 1, the duct board 110 is located at one lateral side of the outlet 600 of the indoor unit of the air conditioner.
In the horizontal direction, the protruding ribs 300 are spaced apart from the air outlet 600.
In this embodiment, a certain distance exists between the protruding rib 300 and the air outlet 600, so as to prevent condensed water from flowing to or splashing to the air outlet 600 in the flowing process, and causing the condensed water to be blown out from the air outlet 600 along with the heat exchange air.
In some embodiments of the utility model, the length of the raised bead 300 is between 30mm and 80 mm.
In this embodiment, the length of the protruding rib 300 is too short, so that the drainage effect of the protruding rib 300 on the condensed water is poor, which is not beneficial for the protruding rib 300 to guide the condensed water to the side far away from the heat exchanger 200, and the protruding rib 300 with too short length cannot provide enough support to ensure the strength of the air duct plate 110. When the length of the protruding rib 300 is excessively long, the molding difficulty and the manufacturing cost of the protruding rib 300 are increased.
The length of the protruding ribs 300 is between 30mm and 80mm, so that the condensate water guiding effect is considered, the structural strength of the air duct plate 110 is also considered, the forming difficulty of the protruding ribs 300 is simpler, and the manufacturing cost of the air conditioner indoor unit is reduced.
In some embodiments of the present utility model, the angle between the raised bead 300 and the horizontal is between 10 ° and 45 °.
In this embodiment, an included angle exists between the protruding rib 300 and the horizontal plane, so that the condensed water can flow along the protruding rib 300 to the end far away from the heat exchanger 200 under the action of gravity, and then flows to the lower side of the air duct frame 100 along the air duct plate 110.
The larger the angle between the protruding bead 300 and the horizontal plane, the greater the flow rate of the condensed water, but the larger the angle between the protruding bead 300 and the horizontal plane, the longer the length and length of the protruding bead 300 is required, making the manufacture of the protruding bead 300 more difficult, when the end of the protruding bead 300, which is away from the heat exchanger 200, is at a certain distance from the heat exchanger 200 in the horizontal direction.
When the included angle between the protruding rib 300 and the horizontal plane is between 10 ° and 45 °, the condensate water can be ensured to flow along the protruding rib 300 at a faster speed, and manufacturing inconvenience caused by the overlong length of the protruding rib 300 can be avoided.
In some embodiments of the present utility model, as shown in fig. 3 and 5, the bottom of the air channel frame 100 is provided with a water tray 400.
The projection of the protruding rib 300 in the vertical direction is inside the water pan 400.
In the present embodiment, the water pan 400 is disposed at the bottom of the air duct frame 100 for collecting and storing condensed water dropped from the heat exchanger 200 or the air duct frame 100, etc. The projection of the protruding rib 300 in the vertical direction is inside the water receiving tray 400 to ensure that the condensed water is effectively guided into the water receiving tray 400 when the protruding rib 300 guides the condensed water.

Seal 500 is fixedly attached to tube sheet 210 at an end adjacent to duct plate 110. The first flange 111 and the second flange 112 are both in interference connection with the sealing structure 500.
In the present embodiment, a sealing structure 500 is provided between the air channel plate 110 and the tube sheet 210 to improve sealing performance between the air channel frame 100 and the heat exchanger 200. The first flange 111 and the second flange 112 are arranged to semi-surround the outer circumference of the sealing structure 500, so that the connection of the sealing structure 500 is more stable. The first flange 111 and the second flange 112 form an interference fit connection with the sealing structure 500 to ensure that no gap exists between the air duct plate 110 and the sealing structure 500, so as to further improve the sealing performance between the air duct frame 100 and the heat exchanger 200.
In some embodiments of the present utility model, as shown in fig. 2, at least one first fixing seat 113 extending away from the air duct is fixedly connected to the air duct plate 110, and a first connection hole is formed in the first fixing seat 113. The tube plate 210 is fixedly connected with a second fixing seat 211 corresponding to the first fixing seat 113, and a second connecting hole is formed on the second fixing seat 211. The first connecting hole and the second connecting hole are aligned.
In this embodiment, the first fixing base 113 is formed with a first connection hole, and the second fixing base 211 is formed with a second connection hole aligned with the first connection hole, so that the first fixing base 113 and the second fixing base 211 are fixedly connected by a fastener, so that the connection between the air duct frame 100 and the heat exchanger 200 is firmer, and the sealing performance between the air duct frame 100 and the heat exchanger 200 is improved.
In some embodiments of the present utility model, the first fixing base 113 is disposed at a middle portion of the air duct plate 110 in a vertical direction.
In this embodiment, the support in the middle of the air duct board 110 is less, and the first fixing base 113 and the second fixing base 211 are provided to connect the air duct board 110 with the heat exchanger 200 more stably, so as to further improve the sealing performance between the air duct frame 100 and the heat exchanger 200.
In some embodiments of the present utility model, the first fixing bases 113 are plural, and the plural first fixing bases 113 are uniformly spaced apart in the vertical direction.
In some embodiments of the present utility model, as shown in fig. 1 or 2, the duct board 110 and the protruding ribs 300 are integrally formed.
In this embodiment, the air duct plate 110 and the protruding ribs 300 are integrally formed, so that the protruding ribs 300 are prevented from falling off from the air duct plate 110, the connection strength of the air duct plate 110 and the protruding ribs 300 is improved, and the service life of the indoor unit of the air conditioner is prolonged.
In addition, the integrally formed structure of the air duct plate 110 and the raised ribs 300 does not need to be assembled separately, so that the manufacture and the installation of the air duct plate 110 and the raised ribs 300 are simpler, and the manufacture time and the cost of the air duct plate 110 and the raised ribs 300 are saved.

The embodiment of the utility model also provides an air conditioner. The air conditioner comprises the air conditioner indoor unit and the air conditioner outdoor unit in any one of the embodiments. The air conditioner outdoor unit is connected with the air conditioner indoor unit.
In this embodiment, the air duct frame 100 is in direct contact with the heat exchanger 200, so that condensed water is easy to be generated on the air duct frame 100, and the protruding ribs 300 inclined towards the lower side far away from the heat exchanger 200 enable the condensed water to be guided to one side far away from the heat exchanger 200, so that the situation that the condensed water formed on the air duct frame 100 is accumulated on the heat exchanger 200 is avoided, and further the situation that the heat exchanger 200 fails due to excessive condensed water on the heat exchanger 200 is avoided, and the service life of the indoor unit of the air conditioner is prolonged.
The air duct frame 100 is easily deformed due to the influence of internal and external pressure, temperature change and other factors in the long-term use process, so that air leakage occurs between the air duct frame 100 and the heat exchanger 200. The protruding ribs 300 are designed on one side of the air duct plate 110 close to the tube plate 210, and play a role in strengthening the structural strength of the air duct frame 100, so that the air duct is not easy to deform, and the sealing effect between the air duct frame 100 and the heat exchanger 200 is improved.
In order to ensure the tightness between the air duct frame 100 and the heat exchanger 200 and the connection stability between the air duct frame 100 and the heat exchanger 200, a large number of sealing sheet metal parts are used for connecting between the air duct frame 100 and the heat exchanger 200 in the existing part of the indoor air conditioner. The use of the sealing sheet metal part not only increases the manufacturing cost of the indoor unit of the air conditioner, but also reduces the sealing effect due to improper installation or long-term use of the sealing sheet metal part.
