Detailed Description
The first embodiment is as follows:
in the first embodiment shown in fig. 1 and 2, the high-efficiency air conditioner indoor unit comprises a base shell (not shown), a cross-flow fan 1 driven by a driving motor (not shown) is horizontally arranged in the base shell, and a serpentine heat exchange tube 2 connected by vertical cooling fins 21 is semi-surrounded at the upper rear of the cross-flow fan 1; the cross-flow fan 1 is made of metal, and the outer periphery of the cross-flow fan is fixed with inner rings 31 of a plurality of fan bearings 3 which are uniformly distributed along the axis of the cross-flow fan; the outer ring 32 of each fan bearing 3 is in heat-conducting contact with the serpentine heat exchange tube 2.
In the air conditioner indoor unit, the vertical radiating fins 21 and the cross flow fan 1 are made of metal aluminum, so that the air conditioner indoor unit has light weight and good heat conductivity.
When the high-efficiency air conditioner indoor unit works, the metal cross flow fan 1 is in direct heat conduction contact with the heat exchange tube 2 through the fan bearings 3, so that heat or cold of the heat exchange tube 2 is transferred to the cross flow fan 1 in a large quantity through heat conduction, and then through the rapid rotation of the cross flow fan 1, air flow flowing through the cross flow fan 1 and fan blades of the cross flow fan exchange heat rapidly and repeatedly, so that the heat exchange efficiency is improved to a greater extent, and the energy-saving effect of the air conditioner is improved.
Example two:
in the second embodiment shown in fig. 3 and 4, unlike the first embodiment, an axial tube 41 fixed to the cross flow fan 1 is further provided on the axial line of the cross flow fan 1; one end of the shaft tube 41 is closed, and the other end is open; one end of the shaft tube 41 is also fixed with a gear coupled with a driving motor; of course, the gear may be formed on the outer periphery of the cross flow fan 1; and the wall of the shaft tube 41 is made of porous material, such as ceramic filter material; as shown in FIG. 4, a thin water cavity 410 is formed in the wall of the shaft tube 41; a top pipe 411 which extends along the axis of the shaft tube and is communicated with the thin water cavity 410 is further arranged at the bottom of the shaft tube 41, and an electromagnetic valve 412 is connected in series in the top pipe 411; the shaft tube 41 is matched with a water storage tube 42 which can be inserted into the shaft tube, the outer end of the water storage tube 42 is provided with a sealing cover 421, and the sealing cover 421 is also internally provided with a one-way valve which points to the inside of the tube from the outside of the tube; a top open valve 422 is arranged at the bottom of the water storage pipe 42, when the water storage pipe 42 is completely inserted into the shaft tube 41, the top open valve 422 is pushed open by the top tube 41, and the water storage pipe 42 is communicated with the thin water cavity 410 through the electromagnetic valve 412; the side surface of the base shell is provided with a plugging hole for plugging the water storage pipe 42 in the shaft pipe 41.
According to the second embodiment, after the water storage tube 42 storing the water is inserted into the shaft tube 41, due to the rapid rotation of the cross flow fan 1, the water in the water storage tube 42 enters the thin water cavity 410 of the shaft tube 41 and is passed through the porous tube wall of the water storage tube 42 under the centrifugal action, and then is volatilized near the cross flow fan 1 in a water mist shape, so that the heat exchange efficiency near the cross flow fan 1 is greatly improved, the heat or the cold on the heat exchange tube 2 is rapidly dissipated into the room, and meanwhile, the air conditioner has the indoor humidifying function. In the second embodiment, the water storage tube 42 is also very convenient to disassemble and assemble, and compared with the air conditioning humidification scheme in the related prior art, the practicability of the second embodiment is greatly improved.
Preferably, in the second embodiment, the inner cavity of the water storage tube 42 is in a circular truncated cone shape, and is thinner near the cover 421 and thicker near the top-open valve 422. Therefore, under the centrifugal action, the water in the water storage pipe 42 flows from the cover 421 to the top open valve 422 to enter the thin water cavity 410. The one-way valve in the cover 421 is used to make the water in the water storage tube 42 fill with air after the water in the water storage tube 42 enters the thin water cavity 410. When the air conditioner is turned off or humidification is not needed, the electromagnetic valve 412 is closed; so as to prevent the water in the water storage tube 42 from continuously seeping out through the tube wall of the shaft tube 41; the more optimized mode is that a humidity sensor is arranged in an air conditioner internal unit, and after the air conditioner is turned off, the cross flow fan 1 is still enabled to continue to rotate for a period of time until the humidity sensed by the humidity sensor is reduced to a set threshold value; therefore, before the air conditioner stops working completely, the water in the shaft tube 41 can be drained, so as to avoid the problems of water dripping caused by gradual seepage and the like.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
