The invention is described in further detail below with reference to the following figures and detailed description:
in order to solve the problem that the air guide plate is prone to frost in the air conditioner in the prior art in the refrigeration mode, as shown in fig. 1 to 7, a first aspect of the present application provides an anti-condensation device, including: circulating fan 1, guide duct 2 and aviation baffle subassembly 3, specifically, aviation baffle subassembly 3 includes: the air guide device comprises an inner air guide plate 4 and an outer air guide plate 5 which are connected, a cavity is formed between the inner air guide plate 4 and the outer air guide plate 5, a cavity is formed in an air guide plate assembly 3, one end of an air guide pipe 2 is communicated with the circulating fan 1, and the other end of the air guide pipe is communicated with the cavity.
In a refrigeration mode, the circulating fan 1 conveys high-temperature indoor air into the inner cavity of the air deflector assembly 3 through the air guide pipe 2, so that the temperature of the inner surface of the air deflector assembly 3 close to the air outlet side of the indoor unit is increased, the temperature difference of the inner surface and the outer surface of the air deflector assembly 3 is effectively reduced, and the phenomenon of frost condensation is avoided, wherein the indoor air is generally 20-25 ℃ and is far higher than cold air blown out by the indoor unit, specifically, the amount of indoor air sucked through the circulating fan 1 is small, and only the temperature of the air deflector assembly 3 can be ensured to be increased without influencing the suction amount of the outlet air temperature of the indoor unit.
Specifically, as shown in fig. 6, the circulating fan 1 includes a casing, a fan blade and a motor, the motor is installed on the casing, the fan blade is installed in the circumferential direction of the motor, an air inlet 7 for allowing indoor air to enter is formed at the top end of the casing, an air outlet 8 communicated with the air guide pipe 2 is formed in the side wall surface of the casing, when the circulating fan 1 is used, firstly, the indoor air is sucked into the circulating fan 1 through the air inlet 7 under the action of the motor, then, the indoor air is conveyed into the inner cavity of the air guide plate assembly 3 through the air guide pipe 2, and at this time, the indoor air flows along the length direction of the air guide plate, so that the temperature of the portion, in contact with cold air, of the inner air guide plate 4 is increased, and the anti-frost effect is ensured.
According to another embodiment of the present invention, as shown in fig. 1, fig. 3 and fig. 4, the inner air guiding plate 4 is provided with a plurality of air outlet micro holes 6, and the specific size of the air outlet micro holes 6 is set to be 2mm, and in order to ensure the frost prevention effect, preferably, the plurality of air outlet micro holes 6 are arranged at equal intervals along the length direction of the inner air guiding plate 4.
