The fan 300 is preferably a crossflow fan with a central axis of rotation extending in a transverse direction. The evaporator 200 is preferably a three-stage evaporator covering the space in front of and above the crossflow blower, and further, may be a finned evaporator.
The number of the fans 300 may be one or more. In the present invention, the number of the fans 300 is preferably 2 to 4. Further, the fan 300 is a cross-flow fan, and the air supply port 110 of the indoor unit 10 corresponds to an air outlet of a volute of the cross-flow fan. When the number of the fans 300 is one, the number of the corresponding air supply outlets 110 may be multiple, each air supply outlet 110 is arranged at intervals, and the air outlet of the volute of the fan 300 corresponds to multiple air supply outlets 110 of the indoor unit 10; when the number of the fans 300 is plural, preferably 2 to 4, each fan 300 may correspond to one air supply outlet 110, the air outlet of the volute of the fan 300 corresponds to the air supply outlet 110 of the indoor unit 10 one by one, and of course, the number of the air supply outlets 110 may be larger than the number of the fans 300.
Preferably, each of the fans 300 is coaxially disposed in a transverse direction of the wall-mounted air conditioning indoor unit 10 and has the same diameter; the air supply outlets 110 have the same transverse width distance, so that uniform air supply is realized, and the overall appearance of the indoor unit 10 is ensured.
In the prior art, the problems of small air induction amount, single air mixing direction, uneven air mixing and the like of an indoor hanging machine exist.
Aiming at the technical problems, the invention provides a technical scheme of additionally arranging the air guide groove 400. The method comprises the following specific steps: the wind guide groove 400 is provided between the air supply ports 110 so that an interval is provided between the adjacent air supply ports 110; wherein the content of the first and second substances,
the induction groove 400 is formed by a gap formed by the supply port 110 to allow the indoor air at the rear of the casing 100 to flow to the supply port 110 through the induction groove 400, and to be mixed with the heat-exchange air to form mixed flow to be blown into the room again.
The forming process of the air guide groove 400 and the forming process of the shell 100 are carried out simultaneously, namely the shell 100 is obtained by deformation in the forming process, the air guide groove 400 is arranged at the interval of the air supply outlets 110 which are independent from each other, and the high-speed airflow of the two adjacent air supply outlets 110 enables the interval of the air supply outlets 110 to form strong negative pressure to form the guide airflow. During air conditioner refrigeration, the induced air groove 400 air current interlude of interval department is inside heat exchange air current wind post, directly mixes wind and temperature exchange at the wind post is inside, thereby form the even mixed wind post of wind that is cold and not cold, because its interval department forms powerful negative pressure, can form the fast-speed induced air current of the big amount of wind, so, the technical scheme of this embodiment not only can realize cold and hot air current interlude formula intensive mixing, can promote the drainage volume simultaneously greatly, thereby promote the cool and comfortable air supply of not cold of user and experience.
As shown in fig. 4, the flow direction of the wind guide groove 400 and the wind delivery opening 110 is visually shown. As shown, the guide groove 400 is located at the middle of the indoor unit 10. The air guide grooves 400 arranged at the interval of the main air columns conduct flow, the main air flow is interrupted, plug-in air guide is formed, the drainage quantity can be improved, meanwhile, the plug-in air guide can be formed inside the main air flow to form air guide mixing, the uniformity of mixed air is greatly improved due to the fact that the air guide flow and the main air flow are fully mixed, and comfortable experience is improved.
In the cooling mode, the temperature of the mixed flow air is higher than that of the heat exchange air, and in the heating mode, the temperature of the mixed flow air is lower than that of the heat exchange air. The invention can avoid the heat exchange wind with too low or too high temperature from blowing to the human body to cause discomfort to the human body. In a word, the air-conditioning indoor unit 10 blows the mixed flow air to the indoor, so that the air is softer, the comfort level of air supply is improved, and the wind sensation experience of a user is improved. Meanwhile, since the additional indoor air is mixed into the heat exchange air, the total air volume of the supply-air outlet 110 is increased, and the cooling/heating speed is increased.
In some preferred embodiments, the upper portion of the wind-inducing groove 400 extends from the rear to the front in an arc shape along the housing 100. Further, in the process of extending from the rear to the front, both side walls of the air guide groove 400 include an air blowing section extending smoothly from the rear end to the front, and an air guide section extending obliquely from the front end of the air blowing section to the front end of the air guide groove 400 toward the air blowing port 110 side.
In the forming process of the air inducing groove 400, the shape of the air inducing groove 400 is ensured to be arranged along the flowing direction of the airflow as much as possible, the upper part of the air inducing groove 400 extends in an arc shape, the air at the rear side of the indoor unit 10 is facilitated to flow to the front part of the indoor unit 10, and the flowing resistance of the air is reduced; an air supply section and an air guide section are formed on the side wall of the air guide groove 400, wherein the air supply section helps to change the flow direction of the air flow sent to the front of the indoor unit 10, the air guide section helps to make the air flow more to the direction of the air supply opening 110 of the indoor unit 10 and be sufficiently mixed with the heat exchange air to be sent to the indoor, and the air supply section and the air guide section further help to reduce the wind noise.
Preferably, in order to achieve a better air guiding effect, the horizontal distance of the air guiding section is 3-5 cm. If the horizontal distance of the air guide section is too short, a good air guide effect cannot be achieved on the air flow, the air flow of the air guide groove 400 is easily dispersed before meeting with the main air flow, the wind noise is large in the flowing process, the mechanical energy loss is large, and a good air mixing effect cannot be achieved.
The lateral width of the wind guide groove 400 is smaller than the lateral width of the air blowing port 110. The air mixing area is increased to the maximum extent, so that the air mixing quantity and the air mixing effect reach the maximum extent.
Preferably, the ratio of the transverse width of the air induction groove 400 to the transverse width of the air supply opening 110 is 1: 10-1: 5, and the transverse width of the air induction groove 400 is selected to make the heat exchange air from the air supply opening 110 account for most of the air supplied into the room, and the mixed air is finally supplied into the room under the guidance of the air deflector 500, so as to ensure the stability of the indoor temperature and provide cool but not cold air supply experience for users.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
