Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments.
Referring to fig. 1, fig. 1 illustrates an exemplary wall-mounted air conditioning indoor unit 100, which includes a casing 110, a heat-exchange air inlet duct 120, a heat exchanger 130, a heat-exchange air outlet duct 140, a fan 150, and a non-heat-exchange air outlet duct 160; the housing 110 generally includes a frame 111 and a cover 112 installed at the front side of the frame 111, the cover 112 is formed with an air inlet 113, the frame 111 is formed with an air outlet 114, and is located at the lower part of the frame 111; the heat exchange air inlet duct 120 is formed in the housing, is communicated with the air inlet 113, and forms an air inlet channel of indoor air flow to be subjected to heat exchange with the heat exchanger 130; the heat exchanger 130 is arranged in the heat exchange air inlet duct 120 and is used for exchanging heat with indoor air flowing into the heat exchange air inlet duct 120 from the air inlet 113 to form heat exchange air; the heat-exchange air outlet duct 140 is formed in the casing 110, is communicated with the heat-exchange air inlet duct 120, and is used for guiding heat-exchange air to the air outlet 114; the fan 150 is disposed in the heat-exchanging air outlet duct 140, and is configured to drive the indoor airflow entering the casing to flow toward the air outlet 114; the non-heat-exchange air guide duct 160 is communicated with the air inlet 113 and is positioned below the heat exchanger 150, and the non-heat-exchange air guide duct 160 is simultaneously communicated with the heat-exchange air outlet duct 140, so that indoor air flow entering the non-heat-exchange air guide duct 160 through the air inlet 113 is directly mixed with heat-exchange air at the heat-exchange air outlet duct 140; and the non-heat-exchange air-guiding duct 160 has an opening/closing mechanism 190 for opening/closing the non-heat-exchange air-guiding duct 160.
When the fan 150 operates, the air flow entering the indoor unit from the air inlet 113 is divided into two paths, one path passes through the heat exchange air inlet duct 120 and then exchanges heat with the heat exchanger 130, and the heat exchange air formed after heat exchange enters the heat exchange air outlet duct 140 along with the operation of the fan 150; the other path of the mixed air enters the non-heat-exchange air guide duct 160 and is directly mixed with the heat-exchange air at the heat-exchange air outlet duct 140 to form mixed air, and the mixed air is blown out from the air outlet 114 along with the operation of the fan 150. The airflow direction of the wall-mounted air conditioner indoor unit is as shown by the arrow in fig. 1, and because the temperature of indoor airflow which is not subjected to heat exchange is higher than that of heat exchange air, the indoor airflow and the heat exchange air are mixed to output air more softly and cool rather than cool, and the comfort level is improved. Meanwhile, only a non-heat exchange air guide duct 160 is formed in the indoor unit and is guided by the air inlet 113, and no additional guide hole is needed, so that the change of the existing wall-mounted air conditioner indoor unit is reduced as much as possible; furthermore, through setting up opening and closing structure 190 for the break-make to non-heat exchange wind drainage wind channel 160 is controlled, and when non-heat exchange wind drainage wind channel 160 switched on, the air conditioner possessed the even wind air supply function of mixture, and when non-heat exchange wind drainage wind channel 160 cut off, the conventional forced cooling state was resumeed to the air conditioner, in order to satisfy the different requirements of different crowds to the cooling effect of blowing.
Further, in order to not change the shape, size and volume of the original wall-mounted air conditioner indoor unit as much as possible, in this embodiment, the heat exchanger 130 is a two-section heat exchanger, and is located below the air inlet 113 and above the non-heat-exchange air guiding duct 160, and the two heat exchangers are arranged front and back, that is, the two-section heat exchanger includes a front-section heat exchanger 131 and a rear-section heat exchanger 132 as shown in fig. 1, meanwhile, the air inlet 113 is located on a top side plate of the casing 110, specifically, on the top side plate of the casing 112, and the non-heat-exchange air guiding duct 160 is located on the front side of the. At this time, the lowest section of the three-section heat exchanger in the prior art is removed, so that the non-heat-exchange air guide duct 160 is formed, and other structures of the wall-mounted air conditioner indoor unit do not need to be changed.
And a water receiving baffle is arranged below the front section heat exchanger of the heat exchanger and is in contact with the water receiving baffle.
Further, as shown in fig. 1, a water receiving baffle 170 is disposed below the front-stage heat exchanger 131 of the heat exchanger 130, a gap 180 is formed between the water receiving baffle 170 and a front side plate of the casing 110 (specifically, a front side plate of the casing 112), and the gap communicates the air inlet 113 with the non-heat-exchange air guide duct 160. The water receiving baffle 170 can contain condensed water and be used as a water receiving tray. Wherein, the water receiving baffle plate 170 can be fixedly connected with a water baffle plate structure on the inner wall of the housing 112, and the realization is easy.
As shown in fig. 2 and 3, the opening and closing mechanism 190 includes a driving motor 191, a first crank 192, a connecting rod 193, a second crank 194, and an air deflector 195 that turns over to open and close the non-heat-exchange air guiding duct 160, the driving motor 191 is fixedly disposed on the casing 110, specifically on the inner wall of the framework 111, specifically fixed by a motor base, the driving motor 191 is drivingly connected to one end of the connecting rod 193 through the first crank 192, the connecting rod 193 is also drivingly connected to one end of the air deflector 195 through the second crank 194, and the other end of the air deflector 195 is reversibly connected to the inner wall of the casing 110, specifically on the inner wall of one end plate of the casing 112, through a shaft sleeve. The driving motor 191 works, and the crank-link mechanism formed by the first crank 192, the link 193 and the second crank 194 drives the air deflector 195 to turn over, so as to turn on or off the non-heat-exchange air guiding duct 160.
